Systems and methods for stacking product
A product stacking system may include an open bag detection subsystem and a product stacking subsystem. The open bag detection subsystem may agitate bags to cause product to be displaced out of open bags and determine if a bag is open by comparing a weight of the bag after the agitation to a target threshold. The product stacking subsystem may include a robotic arm and a controller that moves the robotic arm between posts of a bin based on an orientation of the bin. A turntable rotates the bin and can operate as an additional axis of movement of the robot.
1. A product stacking system, comprising:
a turntable to support a bin comprising a plurality of posts that extend above an opening of the bin, the turntable to:
rotate the bin during a loading process during which a robotic arm stacks a product within the bin,
track an orientation of the bin as rotation of the bin occurs, and
provide the orientation of the bin to the robotic arm; and
a wrap dispenser to automatically apply a wrap around the plurality of posts as the turntable rotates the bin.
2. The product stacking system of claim 1 , further comprising a robotic arm comprising a securing mechanism to selectively engage a product for manipulation or movement by the robotic arm, wherein during the loading process the robotic arm positions itself based on the orientation of the bin while stacking the product in the bin.
3. The product stacking system of claim 2 , wherein the robotic arm moves in reference to the bin using a plurality of axes, one of which is provided by rotation of the turntable.
4. The product stacking system of claim 2 , wherein the robotic arm moves in reference to the bin using 7 axes, including rotation of the bin by the turntable.
5. The product stacking system of claim 2 , wherein the turntable is integrated with the robotic arm.
6. The product stacking system of claim 2 , wherein the robotic arm determines a position to move the product between the plurality of posts while stacking the product until a height of the product stacked in the bin reaches a threshold level.
7. The product stacking system of claim 1 , wherein the wrap dispenser begins to apply the wrap after a stacked product height reaches a threshold level in the bin.
8. The product stacking system of claim 7 , wherein the threshold level is such that the robotic arm can position the product in the bin over a top edge of the wrap.
9. The product stacking system of claim 7 , wherein the stacked product height is based on an elevation of the robotic arm when stacking the product.
10. A product stacking system, comprising:
a robotic arm comprising a securing mechanism to selectively engage a product for manipulation or movement by the robotic arm; and
a turntable to support a platform to support one or more stacks of the product, the turntable to rotate the platform during a loading process,
wherein, during the loading process, the robotic arm stacks the product on the platform based on the orientation of the platform.
11. The product stacking system of claim 10 , wherein the robotic arm moves in reference to the bin with a plurality of axes, one of which the rotation of the turntable.
12. The product stacking system of claim 11 , wherein the robotic arm moves in reference to the bin with 7 axes, one of which is rotation of the bin by the turntable.
13. The product stacking system of claim 10 , wherein the turntable is integrated with the robotic arm, the turntable to track an orientation of the platform and provide the orientation of the platform to the robotic arm.
14. The product stacking system of claim 10 , wherein the turntable supports a container comprising a set of posts, and wherein a position of the robotic arm during the loading process is based on positions of the set of posts.
15. The product stacking system of claim 14 , wherein the robotic arm determines the position to move the product between the set of posts while stacking the product until a height of the product stacked in the container reaches a threshold level.
16. A method for mechanically stacking a product, comprising:
positioning a bin on a turntable, wherein the bin comprises a plurality of posts that extend above an opening of the bin;
rotating the turntable to rotate the bin; and
positioning a robotic arm to mechanically place a product in the bin based on the orientation of the bin and a location of posts of the bin.
17. The method of claim 16 , further comprising applying shrink wrap around the plurality of posts as the turntable rotates the bin upon a level of product in the bin reaching a threshold level.
18. The method of claim 16 , further comprising positioning the robotic arm between the plurality of posts while stacking the product until a height of the product stacked in the bin reaches a threshold level.
19. The method of claim 16 , further comprising:
agitating a bag containing the product;
weighing the bag after being agitated;
comparing a weight of the bag to a target threshold; and
directing the bag to one of a reject area and a shipping area based on the comparison.
