A device that outputs printed products fed in a product stream into two mutually independent stacks

Abstract

Equipment for outputting printed products fed in a product stream into at least two mutually independent stacks, having: a conveyor belt; a first deflecting roller fixed to a frame; a second deflecting roller movable downstream; The third turning roller that is under the roller and can move together with the second turning roller; the fourth turning roller that the conveyor belt is guided to and is fixed to the frame under the third turning roller; the second and third turning rollers are parallel to The horizontal plane is moved from a first output position to an actuator in a second output position, in which the printed product is conveyed with its leading side first to the first product arranged for the first stack On the first stop above the receiving space, in the second output position the printed product is conveyed with its leading side first to another stop arranged above the other product receiving space for another stack ; first and second adjustment means for changing the distance between the bottom of the first and second product receiving spaces and the horizontal plane.

Description

technical field [0001] The present invention relates to a device for outputting printed products, in particular book blocks or books, supplied in a product stream, into at least two mutually independent stacks. Background technique [0002] From DD 233545 A1, CH 663385 A5, DE 19628128 B4 and DE 19628129 B4, cross stackers and book block stackers are known, which are arranged behind a bookbinding machine during the production of printed products supplied in a continuous product stream. No suggestion can be drawn from the above-mentioned document to output printed products with different specifications into a plurality of mutually independent stacks without production stoppage, and the apparatus disclosed in the above-mentioned document likewise does not allow production without production stoppages. Change the specification settings. [0003] Furthermore, the above-mentioned cross stackers and book block stackers are relatively complex in terms of technology and because the ...

AI Technical Summary

Problems solved by technology

No suggestion can be drawn from the above-mentioned documents to output printed products with different formats into several mutually independent stacks without production interruption, and the equipment disclosed in the above-mentioned documents also does not allow Change specification settings

[0003] Furthermore, the above-mentioned cross stackers and book block stackers are relatively technically complex and, since the components that move with the machine cycle are prone to disturbances and are expensive, these machines are mainly used in conjunction with high-production printing machines, which however are Small batch orders are usually too expensive

[0004] Another problem with the above-mentioned cross stackers and book block stackers is that they cannot be used simultaneously as output devices for multiple perfect binders, or for processing products from one or more digital printing machines, because due to lack of Mixed runs with different print products or print products with different formats not possible due to changeover during standstill for different formats
