Abstract

A device for continuously delivering bags includes at least one bag transferring device and at least one linear conveyor. The bag transferring device transfers the bags to the at least one linear conveyor. An objective of the invention is to provide a device for delivering bags, which ensures a continuous subsequent processing of the bags at a high rate and with a high degree of reliability. To this end, the device includes a continuously operating linear conveyor with bag holding fixtures. The width of the bag holding fixtures, in the direction of conveyance, is greater than the width of the bags to be held. This enables the linear conveyor to avoid having to be stopped during the delivery of the bags by the bag transferring device, and a continuous delivery of the bags to a next bag handling device can be ensured.

Claims

1. A device for continuous delivery of bags with at least one bag delivery device and at least one linear continuously operating conveyor, whereby the bag delivery device delivers the bags to at least one linear continuously operating conveyor, and wherein the at least one continuously operating linear conveyor includes bag receivers and a width of the bag receivers is greater in conveying direction than a width of the bags to be received.

2. The device of claim 1, wherein the bag receivers are attached to the at least one linear conveyor or have receiving elements formed on the at least one linear conveyor.

3. The device of claim 1 or 2, wherein the linear conveyor is provided with at least one lateral guide rail guiding the bags.

4. The device of claim 2, wherein the receiving elements are provided with at least one opening in the cross-sectional surface perpendicular to the conveying direction and the at least one opening is adapted to a lateral guide rail.

5. The device of claim 1, wherein a second, continuously operating linear conveyor with bag receivers is provided and the two linear conveyors are installed across from and parallel to each other.

6. The device of claim 5, wherein the two linear conveyors across from each other are laid out so as to converge conically in the conveying direction.

7. The device of claim 5, wherein the width of the bag receivers of the two linear conveyors is greater than or equal to the double width of the bags to be received.

8. The device of claim 1, wherein a plurality of bag transfer devices is provided.

9. The device of claim 8, wherein the plurality of bag transfer devices are provided with feeder stations equipped with a hopper.

10. The device of claim 1, wherein at least one belt conveyor is provided as the at least one linear conveyor.

11. The device of claim 1, wherein the linear conveyor is provided with at least one lower guide rail guiding the bags.

12. The device of claim 5, wherein a plurality of bag transfer devices is provided.

13. The device of claim 12, wherein the plurality of bag transfer devices are provided with feeder stations equipped with a hopper.

14. The device of claim 5, wherein a belt conveyor is provided as the second linear conveyor.
