Abstract

Method and apparatus for transferring large stacks of endless paper from a printing machine onto a pallet. The stacks are laid out on the air cushion of a delivery table (1) constructed as a pneumatic table and, suspended on the air cushion, are conveyed to the receiving table (3) of a stack turner (4), which is likewise constructed as a pneumatic table. In the stack turner (4), the pallet is placed on top and the package comprising stack and pallet is pressed together and turned over. <IMAGE>

Description

The invention relates to a method and a direction for the transfer of continuous paper large stacks of a printing press on a pallet.

The invention is therefore concerned with a method and a device with which, for example, zigzag folded endless stacks with a height of 1 m from the printing press to a standardized Euro pallet should be set. Since such stacks with a Height of 1 m due to its heavy weight, for example no longer assign 50 to 80 kg to the Pa by hand Latvians can be implemented, so far With the help of cranes, shafts etc. on the pallets raised. It is extremely difficult to do several such stacks complete in every common format to put on a pallet since the stacks are at an angle directed and in the same flight or direction have to stand on the pallets. The previous procedure, to lift the individual piles onto the pallets and there aligning is extremely complex and with high difficulty in aligning the stacks connected.

The object underlying the invention is therefore in an apparatus and method for order placing stacks of continuous paper from a printing press to create a pallet that enables the stacks in a simple and easy way correct alignment on the pallet.

This object is achieved according to the invention by Training solved that in the hallmark of Patentan say 1 or 4 is specified.  

In the method according to the invention and he The device according to the invention thus becomes the stack from the printing press completely to the pile turner held on the air cushions by air tables so that easily transported to and from the pile turner can be directed. In the pile turner, the lower one Is also designed as an air table, the desired pallet is placed on top of the stacks arranges, whereupon the stack and pallet package squeezed and completely turned over. There with the whole process the stacks on an air cushion the use of cranes is unnecessary etc. and can align the stack easily respectively.

The following is based on the associated drawing a particularly preferred embodiment of the Er described in more detail. Show it

Fig. 1 is a plan view of an embodiment of the device according to the invention and

Fig. 2 is a side view of the embodiment of the device according to the invention.

The game Ausführungsbei shown in the drawing, the device according to the invention comprises a designed as an air table delivery table 1 , which is arranged so that the zig-zag folded expression of the printing machine in the form of a stack is laid out on the delivery table 1 .

Air tables are known per se and consist of perforated tables, the holes of which attach to an air pressure location are connected. The seal is made by Metal balls through the stack of paper be depressed, the stack then through the Air is slightly raised and floats on the air cushion.  

When the stack is placed on the delivery table 1 , it settles downwards until it has reached the desired height.

In addition to the delivery table 1, namely in the direction of the side of it, another air table is arranged as an intermediate buffer table 2 , the height of the delivery table 1 with the stack being selected so that the stack can be pushed from the delivery table 1 onto the intermediate pouf 2 . The buffer table 2 can have a size that is sufficient to accommodate multiple stacks and corresponds to the size of the pallet to which the stacks are to be transferred.

Subsequent to the intermediate buffer table 2 , a pile turner 4 is arranged, the receiving table 3 of which is also designed as an air table. Under this on receiving table 3 , the forks 9 of the pile turner 4 are arranged. As is particularly shown in Fig. 2, the height of the three tables 1 , 2 , 3 is selected so that the stack can be easily pushed from table 1 to table 2 and from table 2 to table 3 . For this purpose, the intermediate buffer table 2 is provided with a corresponding base 7, and has the on acquisition table 3 of the pile turner a structure 8, on which the holding table 3 is such that in the base of the table 3 position higher than the frame 10 of the pile turner 4 is and the table surface of the table 3 is below that of the table 2 .

The pile turner 4 is provided with suitable markings for the different print formats.

The embodiment of the he described above The device according to the invention operates in the following Wise.  

So that the discharge direction of the printed matter is correct again after being transferred to the pallet, it follows the printout of the printed matter of the printing press so that the zigzag folded sheets of paper are laid out with the head part forward on the delivery table 1 . The large pile formed on the delivery table 1 is pushed floating on the air cushion onto the buffer table 2 and aligned there in the position and location desired for later inclusion on the pallet. If necessary, further stacks of paper can be conveyed from the delivery table 1 to the intermediate buffer table 2 and aligned there in the desired manner.

The one or more stacks on the buffer table 2 are then conveyed onto the receiving table 3 of the pile turner 4 and the markings provided on the pile turner, for example on the receiving table 3 , are accordingly aligned and arranged. A cardboard lower part and, for example, a standardized Euro pallet are placed on top of the stacks aligned and arranged in this way. The package of stacks and pallet is then pressed together and turned over by the pile turner, so that the stacks on the pallet come to the exact desired orientation.

The entire operation, in particular the Ar work of the pile turner 4 , is controlled from a control panel 5 , which is provided on one side of the pile turner 4 .
