[0002]

2. Description of the Related Art A conventional empty container compression apparatus which is the background of the present invention is roughly classified into a roller type in which introduction of an empty container and compression and volume reduction are performed by, for example, a pair of rollers, or a swing type. There is an oscillating plate type that compresses and reduces the volume with a moving compression plate.

[0003]

However, in the conventional roller-type compression device, a roller having a larger diameter is required in order to improve the reliability of the compression process, and the device itself tends to be larger. Further, even in the conventional rocking plate type compression device, a large space is required for the compression process, and similarly, the size of the device tends to be large. Furthermore, in the above-described conventional compression apparatus, in both types, the empty container is transferred to the compression processing unit by freely falling along a guide unit such as a guide plate, so that the residual liquid of the empty container is transferred to the guide unit. May adhere. When the remaining liquid in the empty container is dried, the tackiness may increase. In this case, there is a problem that an empty container is attached to the dried portion of the attached residual liquid and stops during the transfer. That is, both types of compression devices have large external dimensions and weight, and also have many problems in reliability of compression processing. The present invention has been made to solve such a problem, and an object of the present invention is to provide an empty container volume reducing device which is reduced in size and weight and improved in reliability. .

For example, as viewed in FIG. 1, the transfer arm 4 can move forward by rotating to the right and rotate backward by rotating to the left with the pivot 4 a as a fulcrum. A pair of hand members 5 for gripping the body of the empty container 7 are formed at the distal end of the transfer arm 4.

Further, the empty container volume reducing device 10 includes a loading table 6 for placing the empty container 7 to be charged at a predetermined position. The loading table 6 is formed in a dish shape, for example, and is arranged near the compression volume reduction mechanism. Also, in the input table 6 or in the vicinity of the input table 6, when the empty container 7 is placed on the input table 6, an appropriate detection means (not shown) such as an optical sensor for detecting the empty container 7 is provided. Be placed. In this embodiment, the transfer arm 4 is operated in response to an electric signal from the detection means, and the empty container 7 is transferred between the introduction rollers 2 and 2.

The operation of the empty container volume reducing device 10 according to the present embodiment will be described with reference to FIGS. First, the empty container 7 is loaded and placed on the loading table 6.
At this time, the empty container 7 is detected by the detecting means, and it is confirmed that the placed article is the object (empty container 7) to be subjected to the compression and volume reduction process by the present apparatus 10. Then, in response to the electric signal of the detection means, the transfer arm 4 operates and moves forward,
The empty container 7 is gripped by the hand member 5. Further, the transfer arm 4 retreats and transfers the empty container 7 between the introduction rollers 2 and 2. Further, by the rotation of the introduction rollers 2, 2, the empty container 7 is guided and introduced between the compression rollers 1, 1 below while being held between the projections 2a, 2a. The empty container 7 guided between the compression rollers 1 and 1
The compression volume is reduced by one rotation. Thereafter, the compressed and reduced empty container 7 is stored in a treated container collection box 8 provided at the lower part of the housing, and is collected as appropriate.
