Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an empty container volume reduction device.
[0002]
[Prior art]
The conventional empty container compression device that is the background of the present invention can be roughly divided into a roller type in which introduction of an empty container and compression volume reduction are performed by a pair of rollers, or a oscillating compression plate. There is a rocking plate type that compresses and reduces volume.
[0003]
[Problems to be solved by the invention]
However, in the conventional roller type compression device, in order to improve the reliability of the compression process, a roller having a larger diameter is required, and the device itself tends to be enlarged. In addition, the conventional swing plate type compression device also requires a large space for the compression process, and similarly, the device tends to be enlarged.
Furthermore, in the above-described conventional compression device, since both types of empty containers are transported to the compression processing section by free-falling along a guide section such as a guide plate, residual liquid from the empty container is transferred to the guide section. It sometimes adhered. In some cases, the residual liquid in the empty container may increase in stickiness when it is dried. In that case, there is a problem that the empty container is attached to the dried portion of the residual liquid that has adhered and stops in the middle of the transfer.
That is, both types of compression devices have large external shapes and weights, and also have many problems in the reliability of compression processing.
The present invention has been made to solve such problems, and an object of the present invention is to provide an empty container volume reducing device that is reduced in size and weight and improved in reliability. .

DETAILED DESCRIPTION OF THE INVENTION
【Example】
FIG. 1 is a front view showing an embodiment of the present invention, and FIG. 2 is a plan view thereof. The empty container volume reducing device 10 of the present embodiment includes a compression volume reducing mechanism portion disposed in the housing. The compression / volume reduction mechanism portion includes, for example, a pair of introduction rollers 2 and 2 that are spaced apart from each other by a predetermined interval. The introduction rollers 2 and 2 are rotatably supported between support frames 3 and 3 provided in the housing. The introduction roller 2 is provided with a plurality of protrusions 2a at a predetermined interval around the circumference thereof. In this embodiment, as shown in FIG. 1, for example, one introduction roller 2 rotates clockwise and the other introduction roller 2 rotates counterclockwise.
[0008]
Further, for example, a pair of compression rollers 1 and 1 are disposed below the introduction rollers 2 and 2 at a predetermined interval. The compression rollers 1 and 1 are, for example, for compressing and reducing the volume by sandwiching a cylindrical empty container 7 therebetween, and are rotatably supported between the support frames 3 and 3. The compression rollers 1 and 1 are structured to rotate in the same rotational direction as the introduction rollers 2 and 2 described above.
[0009]
The empty container volume reduction device 10 includes an empty container transfer mechanism section that is disposed above the compression volume reduction mechanism section and that transfers and supplies the empty container 7 to the introduction rollers 2 and 2. The empty container transfer mechanism includes a transfer arm 4 for transferring the empty container 7 to be introduced into the volume reduction device 10 between the introduction rollers 2 and 2 of the compression volume reduction mechanism. The transfer arm 4 is rotatably supported between the support frames 3 and 3 by the pivot portion 4a. In this embodiment, the transfer arm 4 is constituted by a link mechanism, for example. For example, when viewed in FIG. 1, the transfer arm 4 can move forward by rotating to the right with the pivot 4 a as a fulcrum, and can move backward by rotating to the left. A pair of hand members 5 that grip the body of the empty container 7 are formed at the tip of the transfer arm 4.
[0010]
Furthermore, the empty container volume reduction device 10 includes an input table 6 for placing the empty container 7 to be input at a predetermined position. The input stand 6 is formed in a dish shape, for example, and is disposed in the vicinity of the compression / volume reduction mechanism portion. Also, appropriate detection means (not shown) such as an optical sensor for detecting the empty container 7 when the empty container 7 is placed on the input table 6 is provided in or near the input table 6. Be placed. In this embodiment, the transfer arm 4 is actuated by receiving an electrical signal from the detection means, and the empty container 7 is transferred between the introduction rollers 2 and 2.
[0011]
The operation of the empty container volume reducing device 10 according to this 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 an object (empty container 7) to be subjected to the compression / volume reduction process by the apparatus 10. Then, in response to the electrical signal from the detection means, the transfer arm 4 operates to move forward, and the hand container 5 grips the empty container 7. Further, the transfer arm 4 moves backward to transfer the empty container 7 between the introduction rollers 2 and 2.
Furthermore, the empty container 7 is guided and introduced between the lower compression rollers 1 and 1 by the rotation of the introduction rollers 2 and 2 while being sandwiched between the protrusions 2a and 2a. The empty container 7 guided between the compression rollers 1 and 1 is compressed and reduced by the rotation of the compression rollers 1 and 1. Thereafter, the compressed and reduced empty container 7 is stored in a processed container recovery box 8 provided in the lower part of the housing, and is appropriately recovered.
[0012]
In the empty container volume reduction device 10 according to the present embodiment, the compression volume reduction processing is performed by a two-stage roller configuration of a pair of introduction rollers 2 and 2 and a pair of compression rollers 1 and 1, thereby reducing the diameter of each roller. It can be significantly reduced. In addition, due to the cooperative action of the transfer arm 4 and the hand member 5, the inlet 6 of the empty container 7 to be compressed can be arranged at a low position on the front surface of the apparatus 10. Therefore, the volume reduction device 10 for the empty container according to the present embodiment can contribute to a significant reduction in the size of the entire processing unit, and can be reduced in size and weight.
[0013]
Further, in the empty container volume reducing device 10 according to the present embodiment, the empty container 7 is transferred in a vertical posture substantially upright by the hand member 5 and the transfer arm 4, and in this state, between the introduction rollers 2 and 2. Since it can be pinched and guided between the compression rollers 1 and 1, the empty container 7 does not fall freely. Therefore, unlike the prior art, the residual liquid in the empty container 7 does not adhere to the introduction rollers 2 and 2. Therefore, the conventional inconvenience that the empty container 7 is attached to the dried portion of the attached residual liquid and stops during the transfer does not occur, and a series of operations of the compression volume reduction process can be stably performed. it can.
[0014]
【The invention's effect】
According to the present invention, it is possible to obtain an empty container volume reduction device that is reduced in size and weight and improved in reliability.
