Abstract

A transfer and dispensing apparatus is disclosed for the conveying and separation of packaging material, cushions or pillows when needed by the operator. When a packer working over a conveyor receives a box that requires void fill, an operating switch such as a foot pedal is depressed to dispense pillows from the apparatus and into the box in a connected strip. When the operating switch is released, the apparatus stops dispensing pillows, separates the continuous strip of pillows along a transverse perforation in the strip, and ejects the end of the separated segment. The packer can then complete packing the box by placing the severed end of the pillows into the box, advance to the next box, and repeat the process. The transfer and dispensing apparatus may be positioned in any convenient location including adjacent to, above or attached to the inflation device.

First claim

What is claimed is:

1. A packaging material transfer apparatus for transferring a chain of inflated pillows connected to each other end to end, comprising:
a motor;
a driving mechanism that includes a plurality of traction members driven around an axis by the motor and positioned circumferentially at predetermined distances from each other corresponding to the distance between valleys of the chain of inflated pillows disposed between inflated portions of the chain of inflated pillows, wherein the traction members are:
operable to move the chain along a curved path around the exterior of the driving mechanism; and
disposed to simultaneously engage separate valleys of the chain of inflated pillows; and

an intake arranged with respect to the axis of the driving mechanism such that the intake and the driving mechanism define a portion of the path that extends upwardly from the intake and curved around the driving mechanism, wherein the intake and the driving mechanism are operable to direct the chain along the path.

2. The transfer apparatus of claim 1 , wherein the plurality of traction members include a radially extending flat surface.

3. The transfer apparatus of claim 2 , wherein the plurality of traction members include bars positioned about an interior support member driven in rotation by the motor.

4. The transfer apparatus of claim 2 , wherein the plurality of traction members comprise paddles that extend radially from the axis such that the paddles rotate about the axis and engage the valleys between the inflated portions of the pillows.

5. The transfer apparatus of claim 1 , wherein the plurality of traction members include rods driven in rotation by the motor.

6. The transfer apparatus of claim 1 , wherein the separate valleys are adjacent to one another.

7. The transfer apparatus of claim 1 , wherein the axis of rotation of the driving mechanism is at an elevated position with respect to the intake, such that the intake directs the chain of inflated pillows up to the driving mechanism.

8. The transfer apparatus of claim 1 , further comprising a storage bin containing the chain of inflated pillows, with the driving mechanism positioned at or above the top of the storage bin such that the driving mechanism receives the chain of inflated pillows from the storage bin and engages the chain of inflated pillows on the traction members.

9. The transfer apparatus of claim 8 , wherein the intake is positioned between the driving mechanism and a storage bin.

10. The transfer apparatus of claim 1 , wherein the intake is tapered allowing the chain to be drawn from the holding bin without catching, breaking or tearing.

11. The transfer apparatus of claim 1 , wherein the intake is adjustable in width allowing for differing widths of chains of inflated pillow.

12. A packaging material transfer apparatus for transferring a chain of inflated pillows connected to each other end to end, comprising:
a motor;
a driving mechanism that includes a plurality of traction members defining radially extending flat surfaces and rotated around an axis by the motor, the plurality of traction members positioned at predetermined circumferential distances from each other corresponding to distances between valleys of the chain of inflated pillows, such that the traction members are operable to draw the chain from a storage unit and move the chain of inflated pillows along a path around the exterior of the driving mechanism; and
an intake arranged with respect to the driving mechanism to align the chain onto a path for tangential movement and engagement of the chain onto the driving mechanism.

13. The transfer apparatus of claim 12 , wherein the intake includes a first portion disposed with respect to the driving mechanism to align the path between the first portion and the driving mechanism.

14. The transfer apparatus of claim 13 , wherein the first portion of the intake is disposed above the path to direct the chain upwardly and tangentially onto the driving mechanism.

15. The transfer apparatus of claim 12 , wherein the intake comprises lateral guide portions positioned on opposite transverse sides of the path to locate the chain transversely with respect to the driving mechanism as the chain passes through the intake while being pulled onto the driving mechanism.

16. The transfer apparatus of claim 15 , wherein the intake adjustable in width to allow the transfer apparatus to be used with pillows of different widths.

17. The transfer apparatus of claim 15 , wherein the lateral guide portions are adjustable to selectively accommodate a first chain of inflated pillows having a first width and a second chain of inflated pillows having a second width.

18. The transfer apparatus of claim 17 , wherein the lateral guide portions include a plurality of walls surrounding the path.

19. The transfer apparatus of claim 12 , wherein the intake includes a flare end that smooths a transition to the intake from the holding bin.

20. The transfer apparatus of claim 12 , wherein separate traction members are disposed to simultaneously engage separate valleys of the chain of inflated pillows.

21. A packaging material transfer apparatus for transferring a chain of inflated pillows connected to each other end to end, comprising:
a storage unit that holds the chain of inflated pillows;
a motor;
a driving mechanism that includes a plurality of traction members rotated around an axis by the motor and positioned at predetermined circumferential distances from each other corresponding to distances between valleys of the chain of inflated pillows, such that the traction members are operable to draw the chain from the storage unit and move the chain of inflated pillows along a path around the exterior of the driving mechanism; and
an intake arranged between a storage bin and the driving mechanism to align the chain onto a path for tangential movement and engagement of the chain onto the driving mechanism, wherein the intake comprises lateral guide portions positioned opposite transverse sides of the path to locate the chain transversely with respect to the driving mechanism as the chain passes through the intake while being pulled onto the driving mechanism.

22. The transfer apparatus of claim 21 , wherein the storage unit comprises a storage bin that holds the chain.

23. The transfer apparatus of claim 21 , wherein the intake includes a first portion disposed above the path and with respect to the driving mechanism to align the path upwardly between the first portion and the driving mechanism to engage the driving mechanism tangentially.

24. The transfer apparatus of claim 21 , wherein the lateral guide portions are adjustable to selectively accommodate a first chain of inflated pillows having a first width and a second chain of inflated pillows having a second width.

25. The transfer apparatus of claim 21 , further comprising the chain, which is fed from the storage unit and which has valleys engaged with the traction members.

26. A packaging material transfer apparatus for transferring a chain of inflated pillows connected to each other end to end, comprising:
a motor;
a driving mechanism that includes a plurality of traction members defining radially extending flat surfaces and driven around an axis by the motor, the plurality of traction members comprising paddles positioned circumferentially at predetermined distances from each other corres
