The invention relates to a device for stacking carrier bags made of plastic film and provided with a grip hole.

So far, the individual, one behind the other, have been ejected from a manufacturing machine for such carrier bags Tote bags stacked on stops. There was a maximum stacking of 50 to 75 bags in a stack possible.

With a production speed of around 130 carrier bags per minute, one batch took the production of one half a minute and then had to be promoted; for example on a step conveyor. The step conveyor could for its part only accept a limited number of stacks; an operator eventually had to carry the stacks away. This took a considerable amount of time.

In contrast, the object of the invention is to assemble stacks with a larger number of bags in order to reduce the operating effort.

To solve this problem, the device is characterized by a conveyor which can be moved forward step-by-step and which is shown in FIG a stacking area protruding upwards, the handle holes of the carrier bags adapted stacking plates for the carrier bags carries and by an aleger for grasping and placing the carrier bags supplied to him on the stacking plates.

Step conveyors with stacking mandrels are state of the art. However, this sponsor has so far been possible do not use for stacking carrier bags. This was only possible thanks to the stacking plates that were now provided.

It has been found to be particularly useful that the two offshoots are arranged on both sides of the conveyor Has stars of suction gripping arms for the carrier bags.

To achieve that. Stern does not hinder the filing and stacking of the carrier bags, but on the other hand close can run around the stacking edges in order to enable error-free stacking, the stacking plates are preferred inclined towards this star.

The lining up of the carrier bags on the stacking plates is facilitated by the fact that the side edges of the stacking r plates next to their upper ends run somewhat towards one another via first roundings and via second roundings merge into an upper transverse edge.

With the device according to the invention, 300 bags at a time can be placed on a stacking plate without difficulty stack, i.e. at least quadruple the stack sizes compared to the state of the art, which increases the workload significantly reduced for the removal of the bags.

The invention is described below using an exemplary embodiment with reference to the accompanying drawings described:

The drawing shows an offshoot 2 with two on both sides of the conveyor 4 for the removal of the stacks arranged and revolving stars 6 and 8, with suction arms 10 for gripping from the manufacturing machine carrying bags 14 emerging and each provided with a handle hole 12. The handle holes 12 are preferably reinforced, for example by doubling the material or applying reinforcement material.

The conveyor 4 can be moved step by step and carries upwardly projecting handles that are adapted to the handle holes 12 in the carrier bags 14 Stacking plates 16 for the carrier bags 14.

The star 8 grips the carrier bags 14 by their edge outside of the handle holes 12 and runs as close as possible to the stacking plates 10 to the To be able to line up carrying bags 14 securely on the stacking plates 16.

The stacking plates 16 are in the direction of this star 8 inclined. If the carrier bags 14 when lined up on the stacking plates 16 by the suction arm 10, which they on the star 8 ,. holds, are stripped, they move away from the suction arm 10 because of the inclination of the stacking plates 16, so that the suction arm 10 can sweep unhindered past the edge of the stack that has already been deposited.

The side edges 18 of the stacking plates run next to their upper ends over the first Roundings 20 slightly towards each other and then go over second roundings 22 in an upper transverse edge 24 over.
