(Cl. 340-1725) ABSTRACT OF THE DISCLOSURE A system for reading and recording information from a number of sources which are selectively grouped for recording purposes. A programmer couples information accumulators with pro-selected and pre-set information sources. Where information is to be recorded for production and payroll control in a manufacturing plant as derived from production-information accumulators and production and employee identification pre-set sources, the system reads the accumulators then records from combinations of the read information and preset production information sources for production control, and from combinations of the read information, pre-set production information and pre-set employee information for payroll control. The programmer Will simultaneously process two information source groupings by staggering and overlapping the sequential functions of reading, storing, recording, resetting the information accumulators, resetting the storing means, and verifying the recorded information. Such that, for example, one group stores information while another is recording its stored information, or one group resets its information accumulators while another group is recording.
This invention relates to apparatus for and methods of recording information.
Production monitoring techniques have become highly refined in the present technology such that it is frequently required to periodically ascertain and record a substantial number of factors concerning the work stations in a plant. For example the Work periods assigned each station are programmed automatically and during each work period the production time interval, the down time interval, the number of productive operations, the code identification of the operation, the part number, the code identification of the assigned employee or employees and various other production control and payroll data is collected and must be recorded. The present invention is concerned with the recording and the verification of the recording of such date as on punch cards together with the control of the sequencing of the operations necessary to derive the data. In particular this invention is intergrated with the apparatus for reading, storing, and resetting information accumulators as disclosed in the United States patent application of Donald J. Collom and Charles G. Mann, Ser. No. 391,084 filed herewith and entitled System For Reading, Recording and Resetting Registered Data.
The present invention is concerned with the means for expeditiously sequencing the aforenoted apparatus and applying the information stored thereby together with certain preset information into recording means. In the case of punch card recording illustrated here the sequence for a given work station involves memorizing the information accumulated in registers for that station, punching a card according to that memorized information, verifying the punched information on that card against the memorized information, resetting the registers from which the information was memorized and resetting the memorizing means.
Frequently a plant includes a plurality of Work stations tion for memory purposes,
which can be operated on the same or different time programs. Accordingly, means for selectively memorizing and recording work stations is required according to their assigned work schedules so that one or a plurlity of work stations up to the total in the plant can be subject to a read-transfer operation in which the information recorded on registers for each station is read and then transferred to a recording medium. Further, a number of alternate work assignments can be made available at the work stations. Thus one or a plurality of employees can be monitored at a station depending upon these assignments.
In order to facilitate the maintenance of plant records it is desirable to record production information and our ployee information selectively. In the punch card recording system of this invention a production record card is produced for each work station and a payroll record car-d is produced for each employee or employee team assigned to the work station. The payroll record includes the information of the production record plus additional information pertinent to the individual employee.
Only a limited interval is available for read-transfer operations. Accordingly, the operation is expedited by avoiding the production of record cards for station and employees which are to be skipped in the program. The cards are verified while the next succeeding card is punched in those instances where succeeding cards receive the same information. Two memory banks are employed so that Work station information can be memorized in one bank while that in the other bank connected to another work station is being utilized in the punch-verify sequences. The driver of the aforenoted copending patent application can thus be alternately applied to a memorizing function for one work station, then while that station is in its punch-verify sequence it is applied to another stait next resets the registers in which information was accumulated for the first station. Shortly thereafter the memory associated with the first station is reset and connected to the registers for a third station so that the driver can apply the information in those registers to the memory while the information in the second memory is being employed in the punch-verify cycle for the second station. The registers of the second station are reset after a card with the information they contain has been verified. Upon completion of the punchverify cycles utilizing the information in the second memory it is reset and the fourth station registers are read into that memory. This occurs while the third stations cards are being punched and verified. It is thus seen that an oddeven sequencing is associated with the two sets of memories in this alternate and overlapping recording.
In accordance with the above, one object of this invention is to facilitate the recording of information from a plurality of sources.
Another object is to expedite the recording operation.
A third object is to avoid unproductive recording cycles of the apparatus.
A fourth object is to verify all recorded information against the memorized information.
These objects are realized by a system which includes as a feature a pair of memory means which are employed alternately and in overlapping sequences.
Another feature is the verification of punched information against that stored in the memory set to establish the punched information.
Another feature is a sequencing means for the Work stations and a similar sequencing means for the panels containing the production and employee data for each work station including means for selectively skipping stations and/or panels without consuming the usual read transfer or record cycle intervals.
The above and additional objects and features of this invention will be appreciated more fully from the following detailed description of an illustrative embodiment of the invention in which:

Before undertaking a detailed description of the illustrative embodiment of this invention the mode of depicting the circuits in across the line form Will be described. In these diagrams relay actuating coils are shown with their control circuits and the contacts operated by the coils are not physically associated therewith in the drawings. Accordingly the relationship of the contacts to their actuating coils is set forth in a marginal index. The diagrams are divided into numbered zones or lines in the right hand margin beginning with the number 301 in FIG. 8. Each actuating coil is listed by its reference symbol in the index to the right of the line number with which it is aligned. Contacts controlled by the actuating coil are listed by the number of the line in which they appear next to the reference symbol and where shown the relay symbol is applied to the contact. In order to distinguish back contacts, those closed when the relay armature is dropped, from front contacts, those open when the relay is dropped, the back contact index position numbers are underlined.
As a further aid in reading the diagrams a list of the relays is set forth in the alphabetical order of their symbols. This includes a brief functional name for the relay and the location of its actuating coil according to the index.

These stations have been designated as H1 through H13, B, F, C, D, E, G, A3-l, A3-2, A3-3 and GS in the left side of the rectangles representing the individual panels in the central station for the monitoring system.
Each work station is provided with a plurality of panels from which information is read into recording equipment such as a punch card machine according to the illustrative embodiment. These panels have several functions and have been assigned classifying designations according to those functions. Each work station has at least one panel designated AA1 for accumulating production information both as to quantity and time. One work station, station B, is provided with two AA1 panels to enable monitoring at two sections of the station. Each work station has a panel designated A2 into which identifying machine and production data can be set. Each work station has at least one panel designated BB1 into which identifying employee data can be set. In the example stations H1 through H13, F, A3-1, A3-2 and A3-3 are each monitored by means of live panels comprising AA1, A2 and three BB1 panels; stations C and D each have AA1, A2 and four BB1 panels; station E has two AA1 panels, one A2 panel and six BB1 panels; station E has an AA1, an A2 and two BB1 panels and stations G and GS each have an AA1, an AA2 and a BB1 panel.
The panels as illustrated in FIG. 2 comprises a production monitoring AAI panel including five register groups, four of which provide information for storage and recording. A work station control (not shown) includes a switch actuated mechanically, photo-electrically, or magnetically, for example, for each significant productive operation whereby units impulses are fed to solenoids driving register wheels 31 on which a count of the units produced is accumulated to form digits. A piece count is similarly accumulated on register wheels 32, for example, as some fraction of the units count or independently thereof depending upon the nature of the operation being monitored. A master clock issues impulses every hundredth of an hour and these impulses are selectively applied to the driving solenoids for down time count on register Wheels 33 and productive time count on register Wheels 34 as determined by the setting of selector switch 35.
A signalling means for indicating conditions at the work station, for example a switch (not shown) manually actuated by the attendant, causes illumination of signal lamps 36 singly or in combination to convey information to the central station production monitoring panel. Within the discretion of the central station attendant the assignment of the work station can be established according to the signals and supplemental information as obtained by telephone through the setting of switch 35 whereby the units and pieces register can be connected or disconnected and the time registers can be conditioned to accumulate production time intervals or down time intervals. In addition, tap switches 37 and 38 can be set to indicate the machine status according to a predetermined code as displayed in the windows 39 and 40 individual to those switches.
Balance register 41 provides a descending count from a preset value as established by setting wheel 42 for either quantity or time as determined by the setting of timequantity switch 43. Thus register 41 can indicate the amount of time remaining of an allocated period for a run or the number of units remaining to be produced to complete a run.
A master program clock (not shown) is available to all work stations. That clock selectively enables the master timer during work intervals assigned to the work station and automatically causes the read-transfer operation according to this invention at suitable times, usually at the end of a work interval. The program setting for each work station is made on tap switch 44 and displayed at window 45. Read-transfer of information from the work station can also be instituted manually by closing read-transfer switch 46.
Complete production control information is provided by the information established in an AAl panel and an A2 panel as shown in FIG. 2. The A2 panel comprises sixteen tap switches which can be set to coded designations for each run. Switches 47 identify the department number as displayed in windows 47A to which the operation is charged. Switches 48 are set to the machine number for producing the part. The type product is set on switch 49 and the operation is coded at switches 50. The part number comprising up to eight digits is set on switches 51.
Payroll or employment information is set on the BB1 panel for each employee, or where appropriate each team of employees assigned the work station. The BB1 panels each have thirteen tap switches for setting a four digit employee code on switches 52, a wage code on switch 53, a labor code on switch 54, a minimum wage code on switches 55, machine quantity code on switch 56, and any special code information on switches 57.
Each of the aforenoted tap switches have ten positions designated as digits 0 through 9. The registers similarly have a wheel for each decade and can be stepped to positions 0 through 9. Information for either production control or employee (payroll) records can be obtained by reading and manually recording the registers and switch settings as displayed at the windows corresponding to each switch.
In accordance with this invention the information is recorded by punching cards of the form depicted in FIG. 3. Two forms of cards are produced. A production control card suitable for ascertaining work station efiiciency, inventory control and the like is produced from the production monitoring panel AAl and the production identification panel A2. A payroll or employee record is afforded by the information available from the production monitoring panel AAl, the production identification panel A2. and an employee identification panel BB1.
As illustrated in FIG. 3 a commercially available punch card having a two coordinate array made up of eighty vertical columns each containing ten digit positions in vertical alignment in the order zero, one through nine is employed as the recording medium. Production control cards are produced by punching columns 1 through 39. The first four columns represent two month digits and two day digits obtained from calendar controls. The fifth through twenty-third columns record information from production monitoring panel AAl as shift in column five, machine status in columns six and seven (derived from the setting of switches 37 and 38), down time" in columns nine, ten and eleven (from registers 33), run time" in columns thirteen, fourteen and fifteen (from registers 34), pieces count" in columns sixteen through nineteen (from registers 32), and units count in columns twenty through twenty-three (from registers 31.). The production identification panel A2 information is recorded in columns twenty-four through thirty-nine of the card as department number in columns twenty-four and twenty-five (from switches 47), machine number in columns twenty-six through twentyeight (from switches 48), product identification in column twenty-nine (from switch 49), operation number in columns thirty and thirty-one (from switches 50), and part number in columns thirty-two through thirty-nine (from switches 51).
The employee or payroll cards contain all of the information of the production control cards plus the individual employee or employee team information as set up on the switches of the appropriate BB1 panel. Columns one through thirty-nine of an employee card are punched as set forth above. The employee information is recorded in columns forty through fifly-two as employee number in columns forty through forty-three (from switches 52), wage code in columns forty-four and forty-five (from switches 53), labor code" in column forty-six (from switch 54), minimum wage code" in columns forty-seven and forty-eight (from switches 55), machine quantity code in column forty-nine (from switch S6), and three special digit columns for supplemental coding in columns fifty through fifty-two (from switches 57).
The remaining columns on the card, columns fiftythree through eighty are available for recording information supplemental to that to be considered here.
In practice a read-transfer operation involves reading the information on the digit registers of panel AAl and that set into switches on panels AAl and A2 and, when appropriate BB1 and causing that information to be punched into one or more cards of the type shown in FIG. 3. Ordinarily not all work stations will be operated on the same time program and some employee panels for work stations which are operating will be ineffective. Accordingly, the system is arranged to expeditiously scan and skip those work stations in the scanning sequence which are not to be subject to a read-transfer operation during the program currently under consideration and those panels for each work station are similarly scanned and skipped when it is desired to avoid punching a card as where the employee for a given BB1 panel is not assigned to the station.
Automatic control of the system is afforded by a master program clock which at predetermined instants of the time institutes a searching operation for a work station assigned to the time program under consideration. Several time programs are simultaneously available from the master program clock. In the example five programs are illustrated. Each work station can be assigned to any one of these programs by means of selector switch 44 on its AAl panel. If all work stations illustrated in FIG. 1 and all panels for those work stations are set to the same program ninety-four cards must be produced in the allotted read-transfer interval. Since this interval is usually brief, as between work shifts, it is essential that the read-transfer be accomplished expeditionsly.
The present sequencing system is employed with apparatus for reading the registers of panel AAl as a digital count and converting that digital count to a binary memory which is employed to establish a digital readout to a card punch machine emitter or other recording device. The recorded information is then verified against the memory settings and when a verification signal is issued the registers are reset by pulsing them to zero according to pulse trains established by the memory values. If those registers are properly reset, the memory and readout are verified and the system operation proceeds, if not, the system is locked up and an indicator is actuated. Much of the above equipment is described in the copending United States patent application Ser. No. 391,084 filed herewith for Systems for Reading, Recording and Resetting Registered Data in the names of Donald J. Collom and Charles G. Mann.
In order to expedite the read-transfer, the system is provided with two memories 63 and 64 as shown in FIG. 4 and has the work stations divided into an odd and even group whereby information previously stored in one memory can be employed in the card punch operation and verification of punched cards for one work station while the information from another work station in the opposite group is being stored. The various sequencing controls of this invention are arranged to enable such overlap and to accommodate it with respect to the skipping of work stations, the skipping of panels, the verification of cards, the reset of registers, the verification of memories and the reset of memories.
P16. 4 depicts a block diagram of the system. A plurality of odd and even work station AAl recording panel groups 61a and 62a are represented in an array with a selecting means represented as individual transfer control relay contacts AAITCR. The AAl panels include digit registers which set up memory circuits 63 and 64 in the odd-even sequence mentioned above. If an odd work station is subject to read transfer, odd-even controls represented by switches 65a, 65b, 65c, 65d, 65c and 65 are as shown. The driver applies a pulse train to the registers of 61a through 65a and contact TCR for the station so that memory 63 is set by a signal applied through 65b. With the memory set according to the reading of the registers, it issues a signal through 658 to emitter 66 which causes the recorder 67 to operate. Information in the BB1 and A2 panels 611) and 62b of the work station being read is set on tap switches which are connected directly to the emitter by means of transfer control relay contacts A2 TCR and subject to the control represented by odd-even selector 65;. In the case of a punch card machine type recorder the card is advanced after it is punched to a vertifier 68 in the form of a card reader. If the punched card reads in accordance with the input signals from emitter 66, operation continues without incident. If a disparity between the emitter 66 signal and the verifier 68 signal exists the recorder is stopped by recorder lockout 69. With the verification of the card and the continuation of operation of the recorder during the final portion of its card cycle it issues a reset actuating signal on lead 70 to the driver. The driver issues a series of pulses to the register reset and only certain of those pulses are effective on the various registers of the AAl panel as determined by the setting of the memory 63 or 64 and the odd-even control 650 from the memory to the register reset. The signal pulses from the register reset are passed through odd-even control a to the registers in the AAI panel to drive those registers in step-by-step fashion to their reset values. If all registers are properly reset the memory is then reset and conditioned to receive information from the next effective work station of its group.
General operation In the above general description referring to FIG. 4 symbolic representations have been employed to simplify the system concepts. In actual practice a number of sequences are interrelated to effect the coupling and decoupling of the information sources, the driver, the card punch machine used as a recorder, and the card reader used as a verifier of the recorded information. Accordingly, the odd-even switches 65 are only symbolic of those coupling means and a number of relay contacts and sequences must be considered in the detailed description which follows to accomplish those transfer results. The transfer control relay contacts shown in FIG. 4 are also only symbolic. As will be noted below, for example, transfer control relays for the information in BB1 panels are employed as adjuncts to the transfer control relays AZTCR in coupling BB1 panels to the punch and verify equipment.
Clocking of the sequences is based upon the operation of the recording device, the card punch machine. That clocking is accomplished as the completion of a card cycle is approached by briefly opening a normally closed circuit so that as each cycle is terminated the circuit is opened and is then reestablished immediately prior to the initiation of the next cycle. In the specific card punch employed each card cycle comprises ten punch cycles, one for each of the values zero through nine. During each punch cycle all digits of that value are punched by energizing their punch solenoids and following withdrawal of the punches the card is advanced to place its next punch position in the machine punch station or in the case of the final punch value, nine, the card is advanced out of the punch section and a new card introduced. Each punch cycle for the value nine involves a cam rotation which opens the clocking contact for one half cycle between the second and seventh tenth of that cycle, i.e. between cycle 9.2 and cycle 9.7. It is this operation that sequences the system.
Once a read-transfer is initiated the card punch issues two blank cards and then punched cards according to the programming of the system. The first card cycle sets up the proper sequencing of the equipment such that during the second card cycle the first programmed odd work station registers are coupled to the driver and the odd memory and the driver is actuated to a read cycle. The drop of relay X-CR at Q41 of FIG. 9 initiates the driver read pulse train. The driver pulses the registers with ten pulses to advance each through a cycle and a marker signal is issued from the registers as each reaches its nine value to set the memory relay matrix in accordance with a complement in digital form of the count in the register. These matrices establish paths from a plurality of pulse sources derived from the driver to admit the number of pulses required to advance the register to its zero position and establish a path for one digit value representative of that in the regis ter to the cardpunch emitter.
In the chart of FIG. 5 the card cycle in which the second blank card is issued by the card punch is designated the zero cycle. The remainder of this general discussion will refer to the chart and will designate card cycles according to the chart numbering system so that the first productive card cycle, cycle 1 of the chart, is in fact the cyc e in which the third card is advanced through the card punch. Operating intervals in this chart are numbered 0 through 15 across its top. The operations performed in each card cycle are listed in vertical columns of the table as M for setting a memory, P for punching a card, V
for verifying a card, R for resetting a memory, for resetting registers of a work station AAl panel, and D for a dry run of resetting a register group. The horizontal lines in the table represent the sequences to he followed in producing a card from a given combination of panels as information sources. In the extreme left column the reiay selecting the work station is listed.
The column to the right of that containing the selection relay designation identifies the nature of the card being processed as A2 for a production control card including information from panels AAl and A2, and BB1 for an employee card including information from panels AAl, A2 and BB1. In initiating a read-transfer operation assumed for illustration wherein the information for work stations GS, H1, H2 and H3 is to be recorded with only one BB1 card for panel GS, and three BB1 cards for each of panels H1 and H2 and only one BB1 for H3, the initial operation is the reading and transposing the digital count in the registers of the AAI panel for Work station GS into a binary code memorized in odd memory 63.
Following the setting of the odd memory, the information in that memory together with that in the tap switches of panels AAI and A2 is connected to the card punch emitter 66 through transfer control relay AZTCR of FIG. 17 under the influence of the work station stepping sequence of FIGS. 13 and 14 as represented in FIG. 4 by odd-even switching means 65e coupling emitter 66 to memory 63 through contact AZTCR and by odd-even switching means 65f coupling panel A2 through contact AZTCR. During this card cycle the card is punched.
Once the successive read-transfer sequences are initiated, the reading of information into one memory is followed by the reset of the registers associated with the other memory whereby that memory is conditioned to read a new set of registers in the following card cycle. The reset involves actuating the driver to issue a train of pulses by dropping relay VCR at 343 in FIG. 9 and selectively applying through the AAl panel transfer control relay for that station, shown in FIG. 16, pulses from that train, as established by the memory for each register, to the respective registers to drive those registers from their read positions to their reset positions, zero in the example. Thus, during the first productive card cycle the drive is actuated to issue a reset pulse train as indicated at D in the third line of the chart. Since the even memory is not associated with an even work station at this time no AAITCR relay for the even stations is energized in FIG. 16, thus reset train has no effect.
At the end of the first productive card cycle the first punched card is advanced to the card reader for verification against its information sources; the memories and tap switches for the odd AAl and A2 panels, another card is punched, in this instance With information from the same information sources and the tap switches of a BB1 panel for the station; and the memories for the even work stations are set by reading the registers of the AAI panel of the next programed even work station.
The first punched card is verified against its information sources by coupling the card reader to those sources through contacts of its AZTCR and punch-verify PVCRA relays of FIG. 17 as shown in detail in FIG. 7. These relays are dependent upon the sequence established by the work station stepping sequences of FIGS. 13 and 14 and the punch card stepping sequences of FIGS. 10, 11 and 12 all synchronized by the master clocking of the card punch. Verification, represented in the chart by the V in the first line column 2, is performed by reading the punched holes in the card against the digit values in the information sources which supply the punch signals for those digits. Thus a transfer control relay of the A2 series is energized during the punching and verifying of each card to couple the information source to either the punch and/or verify means.
The second card to be punched is punched during verification of the first card as represented by the F in the first and second lines of column 2. Since it is an employee card for the same work station as the first card it includes the information of the first card from the AAI and A2 panels and that from an appropriate BB1 panel. This information is coupled to the punch solenoids by the transfer control relay of the A2 series in FIG. 17 so that portions of the same signal path from the same signal sources are utilized simultaneously to punch the second and verify the first card. The supplemental information from the BB1 panel is fed to the punch solenoids for appropriate digits by a transfer control relay and a punch-verify for that panel. The transfer control relay shown in FIG. 20, is controlled by the transfer control relay of the A2 series and by the punch card stepping sequence of FIGS. 10 and 11. The punch-verify relay shown in FIG. 18, is controlled by the punch card stepping sequence of FIGS. 10 and 1 1. Those connections are represented in FIG. 4 where the BB1 panel 61!; is connected through a transfer control contact BB1TCR for the panel of the selected station and odd-even switching means 65 to the emitter 66.
The memory for the next work station is set during the second productive card cycle by coupling the driver, the even memory group and the registers of the next pro grammed even memory group. This is represented in FIG. 5 by M at the third line column 2. The master clocking from the card punch institutes this setting of the memory and establishes the proper interconnections through operation of the punch card stepping sequence and the work station stepping sequence. The appropriate transfer control relay of the AAI series is energized in FIG. 16 to couple the elements and the read operation of the driver is instituted by dropping relay XCR at 341.
In the third punching card cycle the second punched card is verified, the odd registers are reset, the third card is punched and since only two cards are programmed for the first work station the odd memory is reset following the verification of the last card for that work station. These functions are represented in column 3 at the first and second lines by V for verification, in the first line by O for reset of the first odd station registers, and by P in the third line for the first even station card punch. In column 4 at line 1 the memory reset is represented by an R with an arrow to the dividing line between columns 3 and 4 to indicate the reset of the memory group accomplished r by opening the holding circuits for the memory relays through deencrgization of relay MlCR at 494 for the odd memories and relay MZCR at 496 for the even memories. This occurs in the final portion of the card cycle in which the last card for the work station previously punched is verified.
Primary control of the functions in the third card cycle is accomplished by the card punch clocking, the punch card stepping sequence and the work station stepping sequence. Verification of the second card is accomplished through maintenance of the A2 transfer control relay for its work station the BB1 transfer control relay for its panel, the drop of its punch-verify relay PVCRA and the drop of its BB1 punch verify relay for the effective panel. These transfer control relays are dropped during the terminal portion of the card cycle in which the final card of the work station is verified.
The productive card for the next even work station is punched in the third card punching cycle by the coupling, through its A2 series transfer control relays, of its information sources for its AAl and A2 panels to the card punch emitter. At this time that work station AAl series transfer control relay is deenergizcd to avoid the coupling of the driver during the reset by the driver of he opposite group of registers. The punch operation also involves energization of the punch-verify relay PVCRB at 553. In order that the even station punch operation for its first card has its signal separated from the odd station verification for its last card the punch-verify separation relay ZXCR is energized for each card cycle in which
