Abstract

A compacting apparatus (1) for compacting receptacles has a compacting unit (3) with at least one first advancing device (4) for transporting at least one receptacle (G) in an insertion direction (E). The compacting unit (3) is configured to compact the receptacle (G) while the receptacle (G) is transported in the insertion direction (E). A post-compacting unit (5) is downstream of the compacting unit (3) in the insertion direction (E) and has at least one second advancing device (6) for transporting the at least one receptacle (G) through the post-compacting unit (5). The post-compacting unit (5) is configured to compact the at least one receptacle (G) further. Positions of the at least one first advancing device (4) of the compacting unit (3) and the at least one second advancing device (6) of the post-compacting unit (5) are changeable with respect to one another in the insertion direction (E).

First claim

The invention claimed is:

1. A compacting apparatus for compacting receptacles, comprising:
a compacting unit having at least one first advancing device for transporting at least one receptacle in an insertion direction, the compacting unit being configured to compact the at least one receptacle while the at least one receptacle is being transported in the insertion direction;
a post-compacting unit arranged downstream of the compacting unit in the insertion direction, said post-compacting unit having at least one second advancing device for transporting the at least one receptacle through the post-compacting unit, wherein the post-compacting unit is configured to compact the at least one receptacle further, wherein positions of the at least one first advancing device of the compacting unit and of the at least one second advancing device of the post-compacting unit are changeable with respect to one another in the insertion direction; and
wherein the compacting unit has a first housing on which the at least one advancing device is arranged, and the post-compacting unit has a second housing on which the at least one second advancing device is arranged, wherein the positions of the first housing and the second housing are changeable with respect to one another in the insertion direction.

2. The compacting apparatus of claim 1 , wherein the first housing of the compacting unit and the second housing of the post-compacting unit are guided longitudinally together in the insertion direction.

3. The compacting apparatus of claim 1 , further comprising a spring-elastic pretensioning device which pretensions the first housing and the second housing against changing position with respect to one another in the insertion direction.

4. The compacting apparatus of claim 1 , wherein the at least one first advancing device of the compacting unit and the at least one second advancing device of the post-compacting unit form a compression space between one another, wherein the at least one first advancing device of the compacting unit is configured to convey the at least one receptacle into the compression space, and the at least one second advancing device of the post-compacting unit is configured to convey the at least one receptacle out of the compression space, and a size of the compression space is changeable by changing the position of the at least one first advancing device and of the at least one second advancing device with respect to one another.

5. The compacting apparatus of claim 1 , further comprising a control device, wherein the at least one first advancing device of the compacting unit is operable at a first conveying speed for conveying the at least one receptacle and the at least one second advancing device of the post-compacting unit is operable at a second conveying speed for conveying the at least one receptacle and the control device is configured to control the first conveying speed and the second conveying speed.

6. The compacting apparatus of claim 1 , further comprising a first drive apparatus for driving the at least one first advancing device and a second drive apparatus, different than the first drive apparatus, for driving the at least one second advancing device.

7. The compacting apparatus of claim 6 , wherein the first drive apparatus is operatively connected to a plurality of first advancing devices in order to synchronously drive the first advancing devices and/or the second drive apparatus is operatively connected to a plurality of second advancing devices in order to synchronously drive the second advancing devices.

8. A compacting apparatus for compacting receptacles, comprising:
a compacting unit having at least one first advancing device for transporting at least one receptacle in an insertion direction, the compacting unit being configured to compact the at least one receptacle while the at least one receptacle is being transported in the insertion direction, and
a post-compacting unit arranged downstream of the compacting unit in the insertion direction, said post-compacting unit having at least one second advancing device for transporting the at least one receptacle through the post-compacting unit, wherein the post-compacting unit is configured to compact the at least one receptacle further, wherein positions of the at least one first advancing device of the compacting unit and of the at least one second advancing device of the post-compacting unit are changeable with respect to one another in the insertion direction;
wherein the at least one first advancing device and the at least one second advancing device are arranged in an offset manner with respect to one another in a circumferential direction around the insertion direction.

9. The compacting apparatus of claim 1 , wherein the at least one first advancing device of the compacting unit is configured to convey the at least one receptacle for compacting into a hopper formed by the compacting unit.

10. The compacting apparatus of claim 9 , wherein the compacting unit has plural advancing devices arranged in a circumferential direction around the insertion direction around the hopper.

11. The compacting apparatus of claim 1 , wherein the at least one first advancing device of the compacting unit is formed by a chain drive formed from chain links, wherein the chain drive is configured to move in an advancing direction along an outer lateral surface of a hopper during operation of the compacting apparatus such that the at least one receptacle is conveyed into the hopper in the insertion direction.

12. The compacting apparatus of claim 1 , wherein the at least one second advancing device of the post-compacting unit is formed by a chain drive formed from chain links, wherein the chain drive is configured to transport the at least one receptacle further in the insertion direction.

13. The compacting apparatus of claim 1 , further comprising at least one piercing tool for piercing the at least one receptacle, the piercing tool being arranged on the at least one first advancing device and/or on the at least one second advancing device.

14. The compacting apparatus of claim 13 , wherein the at least one piercing tool comprises plural piercing tools arranged respectively on every second chain link on the at least one first advancing device, which is formed by a chain drive having chain links, while a piercing tool ( 601 ) is arranged on every chain link on the at least one second advancing device, which is formed by a chain drive having chain links.
