Abstract

A packing cell for packing products in boxes includes a picking system for picking products and stacking them according to a stacking pattern, a support unit for the stacking process, with a rotatable horizontal shaft for placing a support platform in a predetermined angular position for the stacking process, and a box handling robot to transfer empty boxes towards the support unit and full boxes away from the support unit. A method includes placing the support platform in a predetermined angular position adjacent a product picking system, picking and stacking a number of products according to a stacking pattern on the support unit, and removing from the support unit, with a box handling robot, a box containing the stacked products.

First claim

The invention claimed is:

1. A packing cell for packing products in boxes, comprising:
a picking system for
picking products and
stacking them according to a stacking pattern,

a support unit for the stacking process, the support unit comprising
a support platform comprising a tool changer master plate, and
a rotatable horizontal shaft for placing the support platform in a predetermined angular position for the stacking process, and

a box handling robot arranged to transfer
empty boxes towards the support unit and
full boxes away from the support unit.

2. A packing cell according to claim 1 ,
the packing cell further comprising one or more build-up bases, each provided with a tool changer tool plate adapted to be coupled to the tool changer master plate of the support unit.

3. A packing cell according to claim 2 , one or more of the build-up bases comprising a bottom and one or more walls defining between them a holding space.

4. A packing cell according to claim 3 , one or more of the walls being one or both rotatable and linearly displaceable.

5. A packing cell according to claim 2 , one or more of the build-up bases being adapted to support boxes for receiving the products from the picking system.

6. A packing cell according to claim 1 , comprising at least two support units for the stacking process, each of the at least two support units comprising a support platform with a tool changer master plate and a rotatable horizontal shaft for rotating the support platform.

7. A packing cell according to claim 1 , further comprising a box feeding conveyor, arranged within reach of the box handling robot, for feeding empty boxes to the packing cell.

8. A packing cell according to claim 1 , further comprising a box output conveyor arranged within reach of the box handling robot, for removing full boxes from the packing cell.

9. A packing cell according to claim 1 , the picking system comprising a product feeding conveyor and picking robot arranged to pick products from conveyor and stack them on the support units.

10. A packing method for packing products in boxes, comprising:
operating a support unit to place a support platform mounted on a rotatable shaft in a predetermined angular position adjacent a product picking system,
operating the picking system to pick and stack a number of products according to a predetermined stacking pattern on the support unit, and
operating a box handling robot to remove from the support unit a box containing the stacked products; and
providing at least two build-up bases adapted to different box types and mounting one of the build-up bases on the support platform of the support unit before placing the support platform of the support unit in a predetermined angular position.

11. A method according to claim 10 , the operating the box handling robot to remove from the support unit the box containing the stacked products further comprising:
operating the handling robot to place an empty box on the stacked products on the support unit, and
operating the support unit to rotate the support platform to transfer the stacked products into the empty box, and
operating the handling robot to remove the box from the support unit.

12. A method according to claim 11 , the operating the support unit to rotate the support platform to transfer the stacked products into the empty box further comprising operating the box handling robot to rotate the box synchronized with the rotation of the support platform.

13. A method according to claim 10 , further comprising,
before the operating the picking system to pick and stack products on the support unit, operating the box handling robot to place an empty box on the support unit to receive the products from the picking system.

14. A method according to claim 10 , comprising
providing the support platform of the support unit with a tool changer master plate, and
providing each build-up base with a tool changer tool plate adapted to be coupled to the tool changer master plate of the support platform, and
the mounting one of the build-up bases on the support platform of the support unit further comprising
coupling together the tool changer master plate of the support platform and the tool changer tool plate of the build-up base.

15. A packing cell for packing products in boxes, comprising:
a picking system for picking products and stacking them according to a predetermined stacking pattern;
a support platform for the stacking process;
a rotatable horizontal shaft for placing the support platform in a predetermined angular position for the stacking process;
a box handling robot arranged to transfer empty boxes towards the support platform and full boxes away from the support platform;
one or more build-up bases defining a holding space; and
a tool changer system for attachment of the build-up bases to the support unit, the tool changer system comprising a master plate and one or more tool plates,
the support platform being provided with the master plate of the tool changer system and each build-up base being provided with a tool plate of the tool changer system.
