Abstract

A method for containing a bale of compressible material without straps or wires includes compressing a quantity of compressible material into a bale and introducing the bale of compressed material into a container in the compressed state. The container can be sealed following receipt of the bale. A baler can be used with a press for compressing the material, and a bagging station can facilitate transfer of the bale to the container without straps or wires securing the bale following compression.

First claim

What is claimed is:

1. A strap-less baler for use with a press for compressible materials, comprising:
a frame;
a conveyor, the conveyor including a mobile portion and a load carriage, the load carriage movably mounted to the mobile portion and including a region for receiving a bale from the press; and
a bagger, the bagger including a chute having an entrance and a discharge, the discharge having a bagging mandrel, the bagger configured to receive a bale and move the bale from the entrance to the discharge and the bagging mandrel,
wherein the load carriage is configured to receive the bale in an orientation and reorient the bale about 180 degrees to transfer the bale to the bagger entrance, and
wherein the bale is introduced into the bagger without straps or wires on the bale.

2. The strap-less baler of claim 1 wherein the load carriage includes a plurality of fork sets mounted for rotation about a common axis, the fork sets rotating to reorient the bale.

3. The strap-less baler of claim 2 wherein the load carriage is pivotally mounted to the mobile portion.

4. The strap-less baler of claim 3 including a pivot axis about which the load carriage is pivotally mounted to the mobile portion.

5. The strap-less baler of claim 4 including springs extending between the load carriage and the mobile portion.

6. The strap-less baler of claim 1 including a pusher mounted within the fork sets to facilitate pushing the bale from the fork sets.

7. The strap-less baler of claim 6 wherein the pusher is a transfer plate.

8. The strap-less baler of claim 1 including a transfer station to facilitate transfer of the bale from the load carriage to the bagger.

9. The strap-less baler of claim 8 including a support element mounted to the pusher and a transfer drive cooperating with the support element to facilitate transfer of the bale to the bagger.

10. The strap-less baler of claim 9 wherein the transfer drive is a reciprocating cylinder.

11. The strap-less baler of claim 1 wherein the bagger entrance is located on a side of the bagger and including a discharge transverse to the entrance.

12. The strap-less baler of claim 11 including a bag mandrel at the bagger discharge.

13. The strap-less baler of claim 1 wherein the conveyor includes a track for moving the mobile portion and load carriage between the press and the bagger.

14. The strap-less baler of claim 2 wherein the bagger entrance includes guides configured to cooperate with the fork sets for transferring the bale from the load carriage to the bagger.

15. The strap-less baler of claim 1 including a controller.
