All devices are located on an alignment table for receiving a ream of cuts to be individualized and wrapped with band stock, with each ream of cuts consisting of multiple rows and stacks of cuts, where the depths and number of rows in each ream of cuts is variable.

Description

The invention relates to a device for multiple Bundling of cut stacks, with a variety of side-by-side banding devices, with an upstream feed slide unit, with an investment table to accommodate one to be separated and trimmings to be banded, the trimmings from a large number of rows of blanks exists, and with one of the rows of blanks moving out of the supplied tri and individual moving unit.

With multiple bundlers, such as are known from DE 26 27 610 A1, are by means of Scatter cutters from large sheets of printed sheets Blank stacking giant, for example of postcards, Labels, pocket calendars and the like for the further processing isolated and the isolated Banded sheets or blanks of strips.

Such multiple bundlers can by feed slide units be loaded, such as are known from DE 298 04 929 U1. With such a Feed slide unit will be the individual rows of blanks of a cutting giant to be separated Stack after stack by 90 ° from the working direction shifted by another 90 °, one To be able to feed multiple bundling stations.

A multiple bundler is known from CH-PS 652 675, where the loaded blank stack by a Cross cutters are separated. After this separation the resultant rows of blanks of the same size bundled several times and to individual Cut up stacks of pieces.

Finally, DE 195 02 535 A1 describes a so-called bar bundler known, in which several adjacent Cutting packages separated and into a cutting bar be bundled. For this purpose, this device takes one Strand of blanks lying flat against one another from which a rod to be bundled is then separated becomes.

The object of the present invention is the method of operation to simplify a multiple bundling station and the processing of the cutting giant is more variable shape.

This task is solved by the rows of blanks extend across the working direction 0 and from finished cut stacks with same blank stack depths and same or different Blank stack widths exist, the blank stack depths the rows of blanks can be varied are the rows of blanks with the removal unit back and forth from the supplied trimmings are separable, the feed slide unit, the moving unit and the banding devices arranged side by side straight in the direction of work arranged one behind the other as a common structural unit are formed and the stack of blanks is removed Row of blanks can be individually banded are.

The trimmings consist of pre-cut pieces Blank stack rows of blank stacks with the same Blank stack depths and the same or variable blank stack widths, and in a device for Processing of such a giant is intended that the Feed slide unit, the removal unit and the bundling station straight in a row in one direction are arranged.

With previous multiple bundlers, the tailored ones had to be cut Stack of blanks placed on a feed table and pushed further with a slider of the same width become. To separate them, they had to be moved away and through a cross slide through 90 ° into a bundle position from where they are brought with you further sliders were transported further. This The slide was again set at 90 ° to the cross slide, around the blank stacking rows of the actual bundling station to be able to supply.

With the present invention, the cutting giant with already cut blank stacks of the most varied Row depth and stack width charged and processed in a straight line become. Angled transport feed paths will be avoided and the plant table of the multiple bundler can right from the upstream face cutter be loaded from.

The detachment unit is able to handle the most varied Row depths and stack widths within a trimming line to recognize and move away. The number the blank stack within a blank stack row can be as different as the number the rows of blanks within a blanket.

An operator to be assigned specifically for the multiple bundler can be dispensed with because the staff of the front machine, usually a plan cutter, bundling can trigger with.
