2. Description of the Related Art Generally, in the restaurant industry, employee cafeterias, ramen chains, etc., it is difficult to dispose of raw garbage. In particular, it is necessary to select a storage place and secure a space for the storage place, and also to take into consideration hygiene problems in the food handling business. Further, there is a problem that the cost of transportation and post-treatment is high.

For these reasons, a garbage press machine capable of compressing and processing the volume of garbage has been put into practical use. As a means for compressing such a bulky object as raw garbage, a large-capacity dust storage section is formed, dust is put in, and one side is pressed by a pressing member to compress the raw garbage in the dust storage section. are doing. Examples of the compression means include a jack type manual type, a motor power automatic type, and a rotary type crushing / combining type.

The use of such a food waste pressing machine has the effect that the water is not removed by the press and does not give off an odor, storage is facilitated, and transportation and post-treatment are simplified. .

However, although the compressed solid material has a thin plate shape, its area is the same as the projected area of the first storage portion, and it cannot be made into a small solid material. For this reason, since it has to be compressed in a large area, there is a problem that the pressing force per unit area cannot be increased and the compression ratio cannot be increased.

In view of the above, a compression method has been considered in which the dust container is formed in a movable type and the object is compressed from multiple directions. As a result, objects such as garbage can be compressed into small lumps, the compression ratio can be increased to reduce the volume of solids, and the transportation and post-treatment can be facilitated. .

[0007]

If an object such as garbage is to be compressed into small lumps, it must be compressed from multiple directions as described above, and the structure of the device becomes extremely complicated. , Motion control is not easy. In addition, complicated processes must be set, and it is inevitable that the compression time is lengthened due to the multiple processes. In addition, the manufacturing cost of the device also rises.

[0008]

It is composed of a piston that is deformed according to the shape of the diameter reducing compression portion by a spring body, and reciprocates the piston from the reservoir portion to the diameter reducing compression portion, thereby compressing the object to be compressed in the reservoir portion. It was designed to be compressed in the holding part.

Since the inner diameter of the reservoir portion and the outer diameter of the piston are substantially the same, the object to be compressed in the reservoir portion is compressed by the pressing operation in the position direction of the piston, and the piston is compressed in the diameter reducing compression portion. By deforming according to the shape of the radial compression part, it is possible to compress the object to be compressed while reducing the compression area, which increases the compressive force per unit area and efficiently compresses the object to be compressed. It can be compressed into small lumps and solidified in the compressed object holding part, and the storage part can be made to have a large volume and a large amount of compressed objects to be processed can be charged from the charging port, and compressed objects to be compressed Can be easily taken out from the compressed material outlet formed at the end of the compressed material holding portion , and the storage portion and the compressed material holding portion are formed in a cylindrical shape.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. The present embodiment relates to a garbage compression device.
First, the cylinder 1 is provided with the axis Φ horizontal. This cylinder 1 has a cylindrical reservoir 2 with a large diameter.
And a conical diameter-reducing / compressing portion 3 having the inner diameter of the reservoir 2 as the maximum inner diameter, and a compressed object holding portion 4 having the inner diameter of the diameter-reducing / compressing portion 3 as the inner diameter. is there. An input port 6 connected to a hopper 5 is provided above the storage section 2.
Are formed. A lid 7 that firmly closes the input port 6 is openably and closably provided at the input port 6. In addition, a compressed product outlet 8 is provided at the end of the compressed product holding portion 4, and a lock mechanism (not shown) having high mechanical strength is formed at the compressed product outlet 8 so as to withstand a high pressure. The provided opening / closing lid 9 is hinged.

Next, the piston 10 is provided on the axis Φ. The piston 10 has an outer shape that substantially matches the outer diameter of the reservoir portion 2 and a spring body 12 formed by spirally winding a circular base plate 11 having a large number of holes for draining water and a belt-shaped member. And consists of. This spring body 12
Is wound so as to allow moisture to pass therethrough, and the outer peripheral end portion is fixed to the substrate 11. The inner peripheral end of the spring body 12 is fixed to a piston rod 13 which slidably penetrates through the center of the base plate 11. The spring body 12 of the piston rod 13
A pressing plate 14 having an outer shape that substantially matches the outer diameter of the compressed object holding portion 4 is fixed to the end portion to which is fixed. Next, the other end of the piston rod 13 is connected to the hydraulic cylinder device 15. That is, the piston rod 1
The reference numeral 3 also serves as a piston rod 13 connected to the piston 10 of the hydraulic cylinder device 15.

In such a structure, the piston 10 is moved to the right end of the reservoir 2 and the trash 5 to be compressed is put into the hopper 5 with the lid 7 opened. As a result, the object to be compressed is stored in the storage section 2 via the charging port 6. When a predetermined amount is stored in the storage part 2, the lid 7 is closed. Then, the hydraulic cylinder device 15 is driven. As a result, the piston rod 13 moves the piston 10 leftward and compresses the object to be compressed in the reservoir 2. At this time, the object to be compressed moves to the reduced-diameter compression unit 3 and the compressed object holding unit 4 while being pressed by the piston 10 and compressed. Piston 10
Since the compressive force is weak while is moving in the reservoir 2,
The spring body 12 moves without changing its original shape as shown by the broken line in FIG. 1. Movement is stopped. Therefore, as the piston rod 13 moves, the outer peripheral portion of the spring body 12 is left in contact with the inner diameter portion of the diameter reducing and compressing portion 3, and the piston 10 apparently advances while reducing its diameter to compress the object to be compressed. At the time of this compression, the pressing area of the object to be compressed is gradually reduced, and even if the pressing force of the hydraulic cylinder device 15 is constant, the compressive force per unit area of the object to be compressed is sequentially increased, resulting in a very strong force. Will be compressed in. Further, since the spring body 12 is a belt-shaped member, there is a gap between the members so that water can pass therethrough, and the water contained in the object to be compressed is squeezed by the compression and passes through the piston 10, and finally the reservoir 2 Is discharged from the open part on the right side of.

As a result of being compressed in this way, all the objects to be compressed are pushed into the compressed object holding portion 4, and the pressing plate 14 is pressed.
It is pressed by and changes into a fixed object with a small diameter and small shape.
Then, the compressed solid matter is discharged from the compressed matter take-out port 8 only by opening the opening / closing lid 9 and advancing the piston rod 13 slightly.

In this way, the piston 10 is returned to its original position after the compression process in which the piston 10 is advanced in one direction is completed, until the pressing plate 14 enters the reservoir 2 from the reduced-diameter compression portion 3. Causes the spring body 12 to return to its original shape. Then, the piston 10 stops in a state where it reaches the right end of the reservoir 2 and stands by for the next compression work.

In the above embodiment, the cylinder 1
Although the description has been made assuming that the axis line Φ of the cylinder 1 is horizontal, the cylinder 1 may be erected vertically in practice.
Further, although the state of being driven by the hydraulic cylinder device 15 has been described, any drive source can be used. Further, the object to be compressed can be applied as needed as long as it is a compressible object. The point of the present invention is that the conical diameter reducing compression portion and the piston that deforms according to the shape of the diameter reducing compression portion cause the object to be compressed not only in the compression direction but also in the compression direction by one-way operation of the piston. The point is that it can be compressed three-dimensionally in the direction of movement.
