Abstract

PURPOSE:To improve the handling characteristic of compressed matter by providing three compressors which compress empty cans successively in different directions and boxes. CONSTITUTION:A press box 4 is constituted by connecting the three boxes 1-3 opened upward. The empty cans, introduced and stacked in a hopper 9, fall into the 1st press chamber 5 and the 2nd press chamber 6 and part thereof enter the 3rd press chamber 7. The 1st compressor 10 is driven to primarily compress the empty cans by a press plate 11. The plate 11 is held in a position 12 and the 2nd compressor 15 is driven. The primarily compressed matter is force-fed into the press chamber 7 and are secondarily compressed together with the empty cans in the press chamber 6. The 3rd compressor 25 is driven in the press chamber 7 to compactly compress the empty cans. The variance of the compressive strength is thereby decreased and the handling characteristic of the compressed matter is improved.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an apparatus for compressing empty cans.

(Prior Art) Generally, empty cans of juice, beer, canned goods, etc. are bulky and are therefore compressed during or after collection. One method of compression is to flatten empty cans one by one, but since it is inconvenient to handle a large number of separate flat bodies after compression, many empty cans are compressed at once into blocks. For post-processing, it is preferable to use the scrap as a compression device for this purpose.
As shown in No. 1 and Japanese Unexamined Patent Publication No. 57-62899, a device has been proposed that presses a large number of empty cans placed into a cylindrical body strongly in the uniaxial direction to obtain a compressed product in the shape of a rectangular parallelepiped or short cylinder. has been done.

(Problems to be Solved by the Invention) However, since each of the above-mentioned devices compresses a large number of empty cans only in one axis direction in one process, the empty cans near the center of the compressed product are not compressed. The volume reduction rate is sufficient and the volume reduction rate is low, and the obtained compressed material is a relatively simple flat aggregate.
The flat body is easy to separate into pieces, making it easy to transport compressed materials,
It was difficult to handle in post-processes such as storage and dissolution.

This invention solves the above-mentioned conventional problems, and aims to provide an empty can compression device that has excellent volume reduction properties and can obtain a compressed product that is integrated and difficult to separate.

(Means for Solving the Problems) However, the empty can compression device of the present invention includes a third box having a lid that can be opened and closed at one end, and a press plate that moves back and forth within the third box. a third compressor provided at the other end of the third box; a second box having one end opening into a side wall of the third box; and a press plate that reciprocates within the second box. A second compressor provided at the other end of the second box, a first box having an input port in the side wall and one end opening in the side wall of the second box, and a reciprocating movement within the first box. This empty can compression device includes a moving press plate and a first compressor provided at the other end of the first box.

In this invention, the side wall of the box refers to the wall of the box located on the side with respect to the moving direction of the press plate, and when the moving direction is horizontal or inclined, the upper side wall (ceiling) and the lower It shall also cover the side walls (bottom wall).

(Function) In the empty can compression device of the present invention, the empty cans input from the input port are first compressed in the uniaxial direction by the first compressor in the first box and the second box, and then in the first compressor. The press plate is compressed in the second box and the third box in a direction perpendicular to the compression direction by a second compressor that operates while holding the press plate in a protruding state. By performing the above steps in an appropriate number of directions, the compressed empty cans that are compressed in one direction and then in a direction perpendicular to this are compressed and accumulated in the third box, and then the press plate of the second compressor is compressed. While being held in the protruding state, a third compressor applies a compression force in the third box in a direction perpendicular to the compression direction of the second compressor, thereby obtaining the desired empty can compressed product. This empty can compressed product can be taken out from the third box by opening the lid of the third box.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In the figure, reference numeral 4 denotes a press box, which is formed by integrally connecting a first box 1 and a second box 2, which are substantially box-shaped and open upward, and a third box 3, which is shaped like a rectangular tube.
One end 1a opens to a side wall 2C of the second box 2, and one end 2a of the second box 2 opens to a side wall 3C of the third box 3. As a result, the first press chamber 5 formed in the first box 1 communicates with the second press chamber 6 formed in the second box 2 from the side, and the second press chamber 6 is formed in the third box 3. It communicates from the side with a third press chamber 7 formed in . The first box 1 and the second box 2 are provided with an input port 8 that opens upward, and a lower end portion of a hopper 9 is connected to the input port 8. 10
is a hydraulic cylinder type first compressor attached to the other end 1b of the first box 1, and a press plate 11 attached to the piston rod is movable in the direction of arrow X within the first press chamber 5, and the piston At the time of zero protrusion, it reaches the position shown by the chain line 12 and becomes substantially flush with the side wall portion of the second press chamber 6. 1
3 (see FIG. 4) is a shirt plate whose base is fixed to the press plate 11, and is used to prevent empty cans in the hopper 9 from falling to the rear side of the press plate 11. Further, 15 is a second compressor of a hydraulic cylinder type attached to the other end 2b of the second box 2, and a press plate 16 attached to the piston rod is movable in the direction of arrow Y within the second press chamber 6. When the piston rod protrudes, it reaches the position indicated by the chain line 17 and becomes substantially flush with the side wall surface of the third press chamber 7. 18
(See FIG. 2) is a shirt plate whose base is fixed to the press plate 16, and is used to prevent empty cans in the hopper 7 from falling to the rear side of the press plate 16. Further, as shown in FIG. 2, cutting blades 19 and 20 made of a hard material such as tool steel are provided at the upper edge of the press plate 16 and the lower edge of the upper side wall 2d of the second box 2 opposite thereto. are screwed over the entire width, and constitute a cutter for cutting empty cans caught between them.

Note that if the press plate 16 and the upper side wall portion 2d themselves are made of a hard material that can withstand wear, the provision of these cutting blades can be omitted. On the other hand, a lid 21 is fitted and supported in one end 3a of the third box 3 so as to be movable up and down, and is further guided so as to be movable up and down by a column of a gate-shaped frame 22 which is erected and fixed on the one end 3a. Reference numeral 23 denotes a hydraulic cylinder for opening and closing M21 attached to the folded portion of the frame 22, and the tip of its piston rod is connected to the lid 21. Further, 25 is a third compressor of a hydraulic cylinder type attached to the other end 3b of the third box 3, and a press plate 26 attached to the piston rod is movable within the third press chamber 7 in the two directions of the arrow. .

Next, the operation of the empty can compression device 230 having the above configuration will be explained. First, empty cans are charged and accumulated in the hopper 9, and then the empty cans are transferred from the input port 8 into the first press chamber 5 and the second press chamber 6. A part of the liquid falls and enters the third press chamber 7 via the second press chamber 6. Next, the first compressor 10 is driven to move the press plate 11 in the direction of the arrow X to perform primary compression of the empty can, and while the press plate 11 is held at the chain line 12 position, the second compressor 15 is driven to press the can. When the plate 16 is moved in the direction of the arrow Y, the primary compressed material compressed by the press plate 11 is forced into the third press chamber 7 through the second press chamber 6,
Together with the uncompressed empty cans that had entered the second press chamber 6,
Secondary compression is applied. Next, the first compression 11110 and the second
If the compressor 15 is returned to its original state and the above steps are repeated one or two more times as necessary, the secondary press compressed in the X direction and subsequently in the Y direction will be created in the third press chamber 7. Compressed material? ! It is multiplied by i. Therefore, the third compressor 25 is driven while the press plate 16 is held at the position shown by the chain line 17, and the press plate 26 is advanced to the position shown by the chain line 27, and the secondary compressed material is moved between the press plate 26 and the lid 21 in the closed state. is further compressed in the direction of arrow Z to obtain a block-shaped tertiary compressed product. After that, M21 is opened by the hydraulic cylinder 23, and the press plate 26 is further advanced by the third compressor 25 to discharge the tertiary compressed material out of the third press chamber 7, thereby completing one cycle of compression. Thereafter, the same steps as above are repeated to compress the empty cans in the hopper 9.

In this way, the empty can is moved in the X direction, then in the Y direction perpendicular to this,
Furthermore, since it is sequentially compressed in three different directions (two directions orthogonal to this), the obtained compressed product is compressed and reduced in volume almost uniformly in each part, and the empty can does not become a simple flat body but is folded. Since they are curved and intertwined with each other, the compressed amount of empty cans that make up the compressed product is difficult to separate and separate, which is extremely convenient for handling the compressed product.

The present invention is not limited to the above embodiments, and for example, the first box 1, the second box 2, and the third box 3.
etc. may have a cylindrical shape in addition to a rectangular tube shape. Also the third
The box 3 is installed horizontally parallel to the first box 1, and also installed vertically so that the Z direction is vertical.
The installation direction of each box may be other than the above. In addition, in the above embodiment, the input port 8 is provided over a wide range by penetrating the upper side walls of the first box 1 and the second box 2, so that empty cans are stored in the first press chamber 5 and the second press chamber 6 for a short period of time. It has the advantage of being able to quickly and reliably perform the compression process by filling the space with a large amount of air.
may be provided at least on the side wall of the first box 1.

Further, when the input port is oriented upward, empty cans may be loaded into the input port by a conveyor or manually without using a hopper.

(Effects of the Invention) As explained above, according to the present invention, an empty can is sequentially compressed in three stages in different directions to form a compressed product, so there is little variation in the degree of compression in each part of the compressed product, so the volume is reduced. In addition, the empty cans are deformed into a folded shape, resulting in an integrated compressed product that is difficult to separate, resulting in a compressed product that is easy to handle in subsequent processes such as transportation, storage, and melting after compression. be able to.
