Reference numeral 24 denotes an oil tank 24 installed on a box that covers the fitting / disengaging cylinder 5.
A hydraulic pump 23 with an electric motor 28 is provided. When the compressor main body 21 is mounted on the vehicle, the input shaft of the hydraulic pump 23 can be connected and driven to the vehicle engine transmission via predetermined connecting means. The input shaft of the hydraulic pump 23 can be connected to the electric motor 28 when the compressor body 21 is used with the compressor body 21 fixed to the ground. Therefore, when the compressor body 21 is used by being loaded on a truck bed, the hydraulic pump 2
By connecting the input shaft 3 to the vehicle engine transmission, the hydraulic pump 23 can be driven to rotate on the carrier. On the other hand, when the compressor body 21 is used while being fixed to the ground, the input shaft of the hydraulic pump 23 is connected to the electric motor 2.
8, the hydraulic pump 23 can be driven to rotate on the ground.

When the compressor body 21 is to be loaded on a truck carrier vehicle, the compressor body 21 is arranged in front of the truck bed as shown in FIGS. In this case, the compressor body 21 and the charging hopper 1 are arranged so as to be arranged in the width direction of the carrier. The crane body 16 is loaded on the rear part of the truck bed. Here, the crane main body 16 is fixed to the rear part of the cargo bed via the outrigger 18. The lower boom 1 is located above the crane body 16.
The lower end of the lower boom 19 is rotatably moved via the working cylinder 17. An upper boom 20 is attached to the upper end of the lower boom 19 so as to be able to expand and contract, and a magnetic separator 15 is suspended from a tip of the upper boom 20. The magnetic separator 15 generates a magnetic force when energized, and as shown in FIG. 13, sorts and holds an empty can by suction.
The empty space on the carrier between the crane main body 16 and the compressor main body 21 is a place where the compressed products 22 are stacked.

Next, when the empty can is compressed, the fitting / unloading cylinder 5 is set in the expanded state in advance and the compression cylinder 3
Is shortened. Thereby, the cylinder shaft 7 is positioned above the charging port 14 to open the charging port 14, and the bottom plate 9 is positioned immediately below the compression chamber 2 to form a bottom surface of the compression chamber 2. Then, empty cans are collected and put into the charging hopper 1. Collection of empty cans is carried out on the crane body 16
The magnetic separator 15 is moved to the collection place by the operation described above, and only the iron empty cans are selected and held by suction by energizing the magnetic separator 15. In this state, the magnetic separator 15 is moved to a position directly above the input hopper 1, and the power supply to the magnetic separator 15 is turned off.
Then, the empty cans sucked and held by the magnetic separator 15 fall into the charging hopper 1, and are charged into the compression chamber 2 through the charging port 14. This operation is repeated until the empty cans are completely filled in the charging hopper 1 and the compression chamber 2 (see FIGS. 14 to 16).

In order to compress the stored empty cans, the cylinder shaft 4 may be lowered by the extension operation of the compression cylinder 3. Then, the inlet 14 is closed by the shutter 7 as the cylinder shaft 4 descends, and the empty can is compressed by the compression plate 8 by further descending the cylinder shaft 4. Thereby, as shown in FIGS. 17 to 19, the first compression-processed product 12 is obtained on the bottom plate 9. Thereafter, the cylinder shaft 4 is positioned above the inlet 14 by the shortening operation of the compression cylinder 3. Then, as shown in FIG. 20 to FIG.
, The empty cans are automatically loaded into the compression chamber 2, and new empty cans are stacked and stored on the compressed product 12.

Then, when the cylinder shaft 4 is lowered by the extension operation of the compression cylinder 3 again, the empty can is compressed by the compression plate 8, and as shown in FIGS. Then, the second compression-processed product 13 is obtained. By repeating the above-described operation a plurality of times, as shown in FIG. 26 to FIG. Obtained.

Thereafter, the compression cylinder 3 is slightly shortened so that the cylinder shaft 4 is lifted and separated from the compression-processed product 13. Also, by shortening the fitting cylinder 5,
The bottom plate 9 is moved backward with respect to the compression chamber 2. Then, the bottom plate 9 descends along the fixed support 11 while detaching from the fitted state, and as shown in FIGS. 29 to 31, the compression-processed products 12 and 13 are moved to the base plate 27 between the pair of fixed supports 11. Fall on.

When the fitting cylinder 5 is extended again, the bottom plate 9 moves forward to the compression chamber 2 side. 32 to 3
As shown in FIG. 4, as the bottom plate 9 advances, the compression-processed products 12 and 13 are pushed out by the pushing member 10. When the bottom plate 9 reaches the forward end, the compressor body 21
The bottom plate 9 fits between the lower end surface of the base plate and the fixed support base 11 and stops. When the bottom plate 9 stops, the cylinder shaft 4 is being raised by the shortening operation of the compression cylinder 3, and the input port 14 is still closed by the shutter 7.

Next, when the cylinder shaft 4 is raised by the further shortening operation of the compression cylinder 3, the shutter 7 moves over the inlet 14 and the inlet 14 is opened, and as shown in FIGS. Then, the empty cans fall from the charging hopper 1 into the compression chamber 2 and are stored. After that, the compression cylinder 3 and the fitting / removing cylinder 5 repeat the above-mentioned compression operation, so that the next empty can is similarly compressed to obtain the compressed processed products 12 and 13. In addition, the obtained compression-processed products 12 and 13 are sequentially stacked on a loading platform as a rectangular compression-processed product 22 having a predetermined thickness.

The present invention is not limited to the above embodiment.
In the above-described embodiment, the object to be compressed is an empty can, but a plastic bottle or a paper container for a beverage may be compressed.
