Driven rollers 23, 24 are attached to both ends of the frame 17 so as to freely rotate, and a drive roller 25, a guide roller 26, a take-up roller 27, etc. are attached to an intermediate upper portion, and between the rollers 23-27. The belt 28 is wound around. The upper driven roller 23 also uses the shaft 19 as a roller shaft. The frame 17 is provided with a drive device 29 that interlocks with the drive roller 25, and a receiving plate 30 that comes into contact with the lower path portion of the belt 12 from above.

The frame 31 of the press roller device 11 has its downstream end side attached to a downstream support member 32 from the machine frame 7 via a shaft 33 in the width direction, so that it can swing up and down around a width direction axis 34. Becomes The upstream end of the frame 31 is attached to the upstream support member 35 from the machine frame 7 via a shock absorber 36, and the shock absorber 36 is composed of a spring or the like.

A large-diameter press roller 37 is rotatably mounted on the upstream end side of the frame 31, and a plurality of small-diameter press rollers 38 are rotatably mounted on the downstream side. Cylindrical members 39, 40 are externally fitted and fixed to these press rollers 37, 38. The press rollers 37, 38 are interlockingly connected to a drive device 41 attached to the frame 31 via a winding transmission device 42 and the like. The belts 12, 28 and the tubular members 39, 40 have rough top shapes with uneven surfaces.

A main conveyor device 43 is arranged between the outer ends of the respective conveying press devices 3, and the main conveyor device 43 forms a broken material conveying main line 44 in the form of a belt. Reference numeral 45 is an empty cardboard box which is an example of a broken material, and a portion corresponding to the upper lid is cut and removed as shown in FIG. 7, for example. The end of the broken material transfer main line 44 reaches the processing unit 46 and the like.

 Next, the pressing work in the above embodiment will be described.

The empty cardboard box 45 generated on the shelf side is loaded into the nearby conveyor device 1 and transported on the broken material transport line 2. Then, the cardboard box 45 reaching the end of the conveyor device 1 is transferred onto the lower conveyor 4 of the transfer press device 3 and conveyed on the press line 15. While being conveyed on this press line 15, first the belt driven in the conveying direction
The upper portion of the cardboard box 45 comes into contact with 28, and due to the inclination of the belt 28, the cardboard box 45 is conveyed while being tightly inserted between the belts 12 and 28, and is gradually crushed.

As described above, the flat cardboard box 45 crushed by the press conveyer 5 restores its height to about 1/2 to 1/3 when it is dropped after being pressed, for example, by pulling in air by elastic force. Although it bulges, it is difficult to restore by crushing again by the press roller device 6 immediately after the press conveyor 5 because strong bending and the like occur in the bent portion generated during crushing.

The cardboard box 45 crushed in this way is transferred onto the main conveyor device 43, and the processing section is moved along the broken material transfer main line 44.
It is transported to 46. When the press conveyor 5 and the press roller device 6 are pressed against each other, the frames 17 and 31 automatically move up against the shock absorbers 22 and 36. The press roller device 6 can be prevented from being damaged.

Advantageous Effects of Invention According to the present invention having the above-described configuration, the crushed material conveyed on the crushed material conveying line is passed from its end to the conveyance type press device,
Here, the material can be crushed while being transported, deformed into a flat plate shape, and then transferred to the broken material transportation main line. Therefore, even if there is a large amount of merging, the flat material will merge into the broken material transfer main line, and it will not be clogged. There is no such thing.

In addition, in the conveying press machine, the broken material conveyed by the lower conveyor can be put in a difficult-to-understand shape under the press conveyor and flattened by sequentially crushing it. It can be crushed by the roller device,
As a result, the bent portion generated during the crushing by the press conveyor is given a strong bending tendency, and a flat plate shape that is difficult to restore (bulge) can be formed.

At that time, the crushing by the press conveyor or the press roller device can be efficiently performed while continuously conveying the crushed material, and the control for the crushing operation can be eliminated. Moreover, when the press conveyor or the press roller device is unable to crush, the press conveyor and the press roller device will automatically escape against the shock absorber, thus avoiding the crushing force. It is possible to prevent the press roller device from being damaged.
