Abstract

The invention relates to a supply device for the supply of filled sacks to a palletizing device, comprising a main supply belt for the supply of a first row of filled sacks on a sliding area of the palletizing device, wherein beneath the main supply belt at least one secondary feed belt is assembled for the supply of another row of filled sacks on the sliding area beneath a first row of filled sacks.

First claim

What is claimed is:

1. Supply device for supplying of filled sacks to a palletizing device, comprising:
a main supply belt for the supply of a first row of filled sacks onto a sliding area of the palletizing device, said main supply belt having a first width;
a secondary feed belt located beneath said main supply belt for the supply of another row of filled sacks onto the sliding area, said secondary feed belt having a second width, said secondary feed belt configured to supply said another row of filled sacks beneath the first row of filled sacks;
a turning device having first and second turning positions corresponding to each of said main supply belt and said secondary feed belt, said turning device being configured to orient respective filled sacks for respective first and second widths, said second width being smaller than said first width, said respective filled sacks thereby being differently oriented for said main supply belt and said secondary feed belt;
wherein the main supply belt consists of a single belt and the secondary feed belt is a single belt, the secondary feed belt comprising an actuation device configured to drive said secondary feed belt faster than said main supply belt, to account for said respectively different orienting of said filled sacks, said actuation device comprising one member of the group consisting of:
a motor for driving said secondary feed belt, said motor being faster than a motor driving said main supply belt,
a gear, and
a common actuation device with two output drives and respective transmissions.

2. Supply device according to claim 1 ,
wherein
the main supply belt is designed as a belt conveyor.

3. Supply device according to claim 1 ,
wherein
the main supply belt and the at least one secondary teed belt have parallel conveyance directions.

4. Supply device according to claim 1 ,
wherein
the secondary teed belt comprises an actuation device for a faster actuation than an actuation device of the main supply belt.

5. Palletizing device for a stacking of filled sacks to a sack stacking, comprising a lifting device and a sliding device with a sliding area, a sliding table and a slider for movement of a layer of filled sacks from a sliding area to a sliding table,
wherein
for the supply of the filled sacks a supply device with the features of claim 1 is assembled beneath the sliding device.

6. Palletizing device according to claim 5 ,
wherein
the secondary feed belt of the supply device is shifted beneath the main supply belt in the direction of the sliding direction of the sliding device.

7. Palletizing device according to claim 1 ,
wherein
the turning device comprises at least one member of the group consisting of:
gripper
air pressure nozzles
turning belts with different speeds
slider.

8. Supply device according to claim 1 ,
wherein
the at least one secondary feed belt is designed as a belt conveyor.

9. Supply device for supplying of filled sacks to a palletizing device, comprising:
a main supply belt for the supply of a first row of filled sacks onto a sliding area of the palletizing device, said main supply belt having a first width;
a secondary feed belt located beneath said main supply belt for the supply of another row of filled sacks onto the sliding area, said secondary feed belt having a second width, said secondary feed belt configured to supply said another row of filled sacks beneath the first row of filled sacks;
a turning device having first and second turning positions corresponding to each of said main supply belt and said secondary feed belt, said turning device being configured to orient respective filled sacks for respective first and second widths, said second width being smaller than said first width, said respective filled sacks thereby being differently oriented for said main supply belt and said secondary feed belt, wherein the main supply belt comprises a single belt and the secondary feed belt is a single belt, the secondary feed belt comprising an actuation device, said actuation device comprising one member of the group consisting of:
a motor for driving said secondary feed belt,
a gear, and
a common actuation device with two output drives and respective transmissions.

10. Supply device for supplying of filled sacks to a palletizing device, comprising:
at least one main supply belt for the supply of a first row of filled sacks onto a sliding area of the palletizing device, said main supply belt having a first width;
at least one secondary feed belt located beneath said main supply belt for the supply of another row of filled sacks onto the sliding area, said secondary feed belt having a second width, said secondary feed belt configured to supply said another row of filled sacks beneath the first row of filled sacks;
a turning device having first and second turning positions corresponding to each of said main supply belt and said secondary feed belt, said turning device being configured to orient respective filled sacks for respective first and second widths, said second width being smaller than said first width, said respective filled sacks thereby being differently oriented for said main supply belt and said secondary feed belt;
the secondary feed belt comprising an actuation device configured to drive said secondary feed belt faster than said main supply belt, to account for said respectively different orienting of said filled sacks, said actuation device comprising one member of the group consisting of:
a motor for driving said secondary feed belt,
a gear, and
a common actuation device with two output drives and respective transmissions.
