1. Field of the Invention
The invention relates to a deliverer module for a folder of a press, the deliverer module having a paddle wheel receiving products from a folder and delivering the products to a delivery belt.
2. Description of the Related Art
U.S. Pat. No. 6,443,062 discloses a paddle wheel deliverer for a web-fed rotary press in which a paddle wheel of the paddle wheel deliverer receives products from a folder for subsequent deposition on a deliverer belt. According to U.S. Pat. No. 6,443,062, the paddle wheel of the paddle wheel deliverer is driven by its own controlled-position drive for controlling or regulating the rotational angle position of the paddle wheel in relation to the incoming products via a control system for the motor. The controlled position drive allows the paddle wheel to be displaced to a certain extent to increase the delivery quality of products transferred from the folder to the paddle wheel deliverer. However, the possible adjustments or possible displacements of the paddle wheel deliverer according to U.S. Pat. No. 6,443,062 are limited for adapting the paddle wheel deliverer to product changes.
An object of the present invention is to provide a novel type of deliverer module for a folder of a press that is adaptable for product changes.
The object is met by a deliverer module in which at least the paddle wheel is displaceable in the horizontal and/or vertical direction relative to the folder.
In the horizontal direction, at least the paddle wheel may be displaced relative to the folder such that the products are always transferred centrally or symmetrically to the paddles of the paddle wheel, irrespective of the product width.
By means of displacing at least the paddle wheel in the vertical and, if appropriate, the horizontal direction relative to the folder, it is possible to ensure that the products are transferred to the paddles of the paddle wheel in an accurate position, irrespective of the product thickness. In this way, the delivery quality can be improved considerably as compared with the prior art.
Preferred developments of the invention emerge from the following description. An exemplary embodiment of the invention will be explained in more detail by using the drawing, without being restricted thereto.
Other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings. It is to be understood, however, that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims. It should be further understood that the drawings are not necessarily drawn to scale and that, unless otherwise indicated, they are merely intended to conceptually illustrate the structures and procedures described herein.
In the drawings, wherein like references denote similar elements throughout the several views:
To provide a fold on a copy divided off from the printing material 15, the cutting blade cylinder 12, the folding blade cylinder 13 and the folding jaw cylinder 14 interact such that, as a copy is divided off from the printing material 15 with the aid of a cutting blade 16 of the cutting blade cylinder 12, the copy divided off is held by a pinning device 18 at the start of the sheet and is moved onwards with the rotation of the folding blade cylinder 13. In this way, the copy divided off is moved into a relative position, defined for the folder, between folding blade cylinder 13 and folding jaw cylinder 14. When this relative position is reached, a folding blade 17 of the folding blade cylinder 13 forces the copy into the folding region between the open folding jaws 19 of the folding jaw cylinder 14, and the pinning device 18 releases the copy. The copy held in this way by the folding jaw cylinder 14 is then moved onwards with the rotation of the folding jaw cylinder 14 and, at a suitable position, is transferred from the folding jaw cylinder 14 to the deliverer module 10 according to the present invention.
The deliverer module 10, according to
In addition to the paddle wheel 20, the deliverer module 10 also includes a deliverer belt 23, the paddle wheel 20 depositing the folded copies or products on the deliverer belt 23. A further transport belt 24 can follow the deliverer belt 23. As can be gathered from
At least the paddle wheel 20 is designed such that it can be displaced in the horizontal and/or vertical direction relative to the folder 11, specifically in relation to the folding jaw cylinder 14 of the folder 11. The entire deliverer module. 10 is preferably designed such that it can be displaced in the horizontal and/or vertical direction relative to the folding jaw cylinder 14. In this preferred case, the paddle wheel 20 is displaceable in the horizontal and/or vertical direction together with the individual drive 25, the deliverer belt 23 and stripping devices, not illustrated. Using a deliverer module 10 that can be displaced in this way, the deliverer module may be optimally adapted to changing products, in particular to changing product widths and changing product thicknesses.
The deliverer module 10 can be displaced in the horizontal direction in the sense of the double arrow 26 of
In addition, in the preferred exemplary embodiment, the deliverer module 10 according to the invention may be displaced in the sense of the double arrows 27 and 28 shown in
Accordingly, the deliverer module 10 according to the present invention is distinguished by a large number of possible displacements to adapt the same to varying product thicknesses and product widths of a folded product. For this purpose, the deliverer module 10 can be moved as a unit in the horizontal and vertical direction and parallel to the drop direction of a folded product into the paddle wheel 20 of the deliverer module 10.
In the sense of the invention here, the deliverer module 10 is designed such that it can be displaced both during a machine run and during the machine stoppage.
The deliverer module 10 is mounted and guided in a rail system such that it can be displaced in the horizontal and/or vertical direction.
As indicated in
It is also possible to keep the deliverer module according to the invention in its appropriate functional position by its being pressed pneumatically or hydraulically or in a spring-loaded manner against stops which can be displaced manually or under automatic control. The position of these stops is in turn influenced on the basis of the product, that is to say on the basis of the product thickness and/or product width of a folded copy.
Thus, while there have shown and described and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit of the invention. For example, it is expressly intended that all combinations of those elements which perform substantially the same function in substantially the same way to achieve the same results are within the scope of the invention. Moreover, it should be recognized that structures and/or elements shown and/or described in connection with any disclosed form or embodiment of the invention may be incorporated in any other disclosed or described or suggested form or embodiment as a general matter of design choice. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
