Retail-ready packaging of pouched product
An apparatus for placing pouches in retail-ready cartons includes pouch placer having an elevator assembly having paddles for receiving pouches provided by a first conveyor, and lifting the pouches, and a first robot arm for retrieving a pouch from a paddle of the elevator assembly and placing it in a retail-ready carton.
1. An apparatus for placing pouches in retail-ready cartons, said apparatus comprising a pouch placer comprising an elevator assembly having paddles for receiving pouches provided by a first conveyor, and lifting said pouches, and a first robot arm for retrieving a pouch from a paddle of said elevator assembly and placing said pouch in a retail-ready carton, wherein said first robot arm is configured to retrieve at most one pouch from a paddle and to place no more than one pouch at a time into said retail-ready carton.
2. The apparatus of claim 1 , further comprising a weight-measurement device for weighing a pouch while said pouch is being moved.
3. The apparatus of claim 2 , wherein said weight measurement device is integrated with at least one of said first robot arm and a second robot arm.
4. The apparatus of claim 2 , further comprising a second robot arm for causing pouches to be provided to said pouch placer, said weight measurement device being integrated with said second robot arm.
5. The apparatus of claim 1 , wherein said first robot arm comprises an effector, wherein said effector comprises a clamp having a spatula, an upper gripper, and a lower gripper, wherein said upper and lower grippers have faces opposed to each other for gripping a pouch, wherein said spatula extends from said lower gripper, and wherein, when said clamp lifts a pouch off a paddle, said spatula supports said pouch.
6. The apparatus of claim 5 , further comprising a vacuum source, wherein said spatula comprises a surface having holes in communication with said vacuum source.
7. The apparatus of claim 1 , further comprising a pouch filling machine for providing filled pouches to said pouch placer.
8. The apparatus of claim 1 , wherein said pouch placer is further configured for erecting retail-ready cartons for receiving said pouches and providing said erected cartons to said first robot arm.
9. The apparatus of claim 1 , wherein said elevator assembly comprises a first elevator tower, and a chain for conveying paddles up a vertical section of said first elevator tower.
10. The apparatus of claim 9 , further comprising a second elevator tower and a chain conveying paddles up a vertical section of said second elevator tower, wherein said vertical section of said second tower faces said vertical section of said first tower.
11. The apparatus of claim 10 , further comprising a horizontal guide, wherein said first and second towers are mounted to be horizontally movable along said horizontal guide to accommodate pouches of different sizes.
12. The apparatus of claim 1 , wherein said robot arm comprises an interchangeable effector.
13. The apparatus of claim 1 , wherein said conveyor imparts said pouches with sufficient velocity to reach said paddles from said first conveyor.
14. The apparatus of claim 1 , wherein said paddles are disposed beyond an end of said first conveyor.
15. The apparatus of claim 1 , further comprising a backstop to prevent a pouch from overshooting said paddle.
16. The apparatus of claim 1 , wherein each paddle comprises a lip at an edge thereof for preventing a pouch from falling off said paddle.
17. The apparatus of claim 1 , wherein each paddle is oriented so as to urge a pouch supported thereon to fall off said paddle.
18. The apparatus of claim 1 , wherein said elevator assembly comprises clips for engaging said paddles, thereby permitting said paddles to be interchangeable to accommodate pouches of different sizes.
