Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a waste compressing apparatus, and more particularly to a waste compressing apparatus for reliably compressing metallic waste without using a compression lid or the like.

[Conventional technology]

The waste compression device stores irregularly shaped metal-based waste in a compression chamber in a bulky state with many voids, compresses the waste from above by compression, and laterally compresses it with a lateral pushing member. That is, it is compressed from the biaxial direction to form a compressed body.

FIG. 5 shows the structure of a conventional waste compression device.
In FIG. 5, 10 is a compression chamber, 16 is a compression lid of the compression chamber 10, 28 is a bottom plate of the compression chamber 10, and 30 is a lateral pushing member of the compression chamber 10. The side wall 12 is erected integrally with the bottom plate 28, the compression lid 16 is configured to be rotatable about a support shaft 14 provided on the upper portion of the side wall 12, and a surface 18 on the compression chamber 10 side is formed. In addition, a lateral pushing member 30 that reciprocates toward the side wall 12 and moves on the bottom plate 28 is provided on the surface opposite to the side wall 12. Reference numeral 36 is a cover member integrally attached to the upper end of the lateral pushing member 30. The side pushing member 30 has a rod
38 is provided and incorporated in a hydraulic cylinder 42 attached to a support 40. Reference numeral 46 is a mount for the support base 40. By operating the hydraulic cylinder 42, the lateral pushing member 30 can move on the bottom plate 28. Reference numeral 34 indicates the compression surface of the lateral pushing member 30, and is formed so as to be substantially parallel to the compression surface 13 of the side wall 12.

The compression lid 16 is rotated around the support shaft 14 by applying a force to another support shaft 20 by the operation of the hydraulic cylinder 24 attached to the member 22 outside the side wall 12 with the swing support shaft 26, Compression chamber
10 top faces open or closed on one side.

To store metal waste in the compression chamber 10, the compression lid 16 is opened, and the lateral pushing member 30 is retracted from the compression chamber 10
10 is performed under the condition that the space is sufficiently expanded, and then the lateral pushing member 30 is advanced toward the side wall 12 of the compression chamber 10 so that the waste is compressed on the compression surface 34 of the lateral pushing member 30 and the side wall 12. It is compressed in the lateral direction between itself and the compression surface 13. In this way, when the waste is compressed in the compression chamber 10 to some extent in the horizontal direction, a part of the waste protrudes upward from the upper part of the compression chamber 10 and escapes. It is closed by the operation of the hydraulic cylinder 24, and the waste 18 is pushed into the compression chamber 10 from above by the surface 18 on the compression chamber 10 side and compressed. By repeating the operations of the lateral compression and the pressing compression from above, the lateral pushing member 30 is advanced to the limit where it can be forwardly laterally compressed, while the surface 18 of the compression lid 16 on the compression chamber 10 side is compressed. The upper end of the chamber 10 is pushed and compressed to a substantially horizontal position, and the waste is compressed into the space in the compression chamber 10 formed by the surface 18, the compression surface 13 of the side wall 12 and the compression surface 34 of the lateral pushing member 30. , Formed into a compressed body. (Actual exploitation 62-9209
(Problems to be solved by the invention) However, in the above-described conventional waste compression device, waste is stored and filled in the compression chamber and compressed by the compression lid from above, and further from the lateral direction. Since it is compressed, the use of the compression lid not only complicates the device for mounting or rotating the operation, but also requires the operation time of the rotation operation of the compression lid, which is necessary for the compression treatment of waste. There is a problem in that the whole cycle time is extended and the processing capacity of the waste compression device is hindered.

The present invention solves such a conventional problem,
Without using the compression lid of the compression chamber, bulk metal waste with many voids, etc. is applied in addition to sufficient horizontal force and downward force,
It is an object of the present invention to provide an excellent waste compression apparatus capable of preventing the waste from escaping above the compression chamber and compressing the waste into a compression body in which the amount of residual voids is significantly reduced.

[Means for solving problems]

In order to achieve the above object, the present invention accommodates metal waste in a compression chamber including a bottom plate, a side wall integrally provided on the bottom plate, and a lateral pushing member that reciprocates facing the side wall. In the waste compressing device for compressing, the compression surface of the side wall and / or the compression surface of the horizontal pushing member is formed such that the compression surface interval formed by the compression surface of the side wall and the compression surface of the horizontal pressing member is narrower in the upper portion than in the lower portion. Is inclined from the upper part to the lower part, and the upper part of the side wall is projected above the upper end of the lateral pushing member.

Also, the present invention provides a compression surface of the side wall and / or a compression surface to the lateral pushing member such that a compression surface interval formed by the compression surface of the side wall and the compression surface of the lateral pushing member is narrower in the upper portion than in the lower portion. It is characterized in that only a part of the two compression surfaces is inclined from the upper part to the lower part.

[Action]

The present invention has the following effects due to the above-mentioned configuration. That is, when metal-based waste or the like is housed and compressed in a compression chamber composed of a side wall and a lateral pushing member that reciprocates facing the side wall, when the lateral pushing member is reciprocated, the compression surface of the side wall and / or Alternatively, the compression surface of the lateral pushing member generates sufficient horizontal force and downward force to compress and deform the waste, and even if a part of the waste is projected upward from the upper portion of the compression chamber, the lateral pushing member is The compression and deformation of the waste proceeds by repeating the reciprocating motion of the above, and finally, the waste can be prevented from escaping from the upper part of the compression chamber and formed into a compression body conforming to the shape of the compression chamber. You can In this way, the apparatus can be simplified, the extension of the total cycle time can be prevented, and the processing capacity of the waste compression apparatus can be increased. Further, it is possible to compress the compressed body in which the residual voids are significantly reduced, and it is possible to effectively utilize the compressed body.

In addition, the compression surface of the side wall and / or the compression surface to the lateral pushing member extends from the upper part to the lower part so that the compression surface interval formed by the compression surface of the side wall and the compression surface of the lateral pressing member is narrower in the upper part than in the lower part. By inclining only a part of the two compression surfaces, good compression performance can be achieved corresponding to the shapes and properties of the waste and the compression body, and a sufficiently compressed compression body can be obtained.

〔Example〕

1 to 4, the same members as the constituent members shown in FIG. 5 are designated by the same reference numerals, and the duplicate description thereof will be omitted.

The compression surface 12a of the side wall 12 and the compression surface 30b of the lateral pushing member 30 are arranged so that the compression surface interval formed by the compression surface 12a of the side wall 12 and the compression surface 30b of the lateral pushing member 30 is narrower than that of the lower portion. From the bottom to the bottom.

In the embodiment shown in FIG. 1, the compression surface 12 a of the side wall 12 and the compression surface 30 b of the lateral pushing member 30 are relative to the bottom plate 28. They are inclined to the compression chamber 10 side at an angle, for example, about 60 °. Then, the upper portion of the side wall 12 is extended and projected so as to be located above the upper end of the lateral pushing member 30.

Thus, the sectional shape of the compression chamber 10 is formed into a substantially trapezoidal shape.

In FIG. 1, when the lateral pushing member 30 is retracted in the direction opposite to the side wall 12, the upper side of the compression chamber 10 is at least the lateral pushing member.
By opening the reciprocating range length of 30 and expanding the space of the compression chamber 10, a large amount of irregular-shaped metallic waste (not shown) is directly stored in a bulky state. It shows that it is possible. The side pushing member 30
The retreat is performed under the operation of the hydraulic cylinder 42.

In FIG. 2, when the lateral pushing member 30 is moved forwards to the limit of the side wall 12 under the operation of the hydraulic cylinder 42, it is shown that the waste is laterally compressed. There is. That is, the waste contained in the compression chamber 10 is deformed by compression and is sufficiently compressed to conform to the shape of the compression chamber 10 formed by the side wall 12 and the lateral pushing member 30.

In FIG. 3 (e), following the state of FIG. 3 (d), the lateral pushing member 30 is moved toward the side wall 12 again as indicated by the arrow A, so that the waste 50 whose compression degree has progressed further. The residual voids are significantly reduced and formed in the compact. When the compressed body is not sufficiently formed, by repeating the operation of FIGS. 3 (d) and (e) again, it is possible to avoid the escape of the waste from the upper part of the compression chamber 10. As a result, the waste 50 can form a compressed body having a substantially trapezoidal cross-section that matches the cross-sectional shape of the compression chamber 10 with the residual voids being significantly reduced.

During compression according to FIGS. 3 (a) to 3 (e), the compression surface 12a of the side wall 12 and / or the compression surface 30b of the lateral pushing member 30 exerts a downward force as well as a horizontal force on the compression chamber 10. The waste is generated and the compressive force also acts sufficiently under the concentration force directed toward the center of the waste, and the waste 50 is pressed into the compression chamber 10 to be compressed, so that the waste is sufficiently compressed and the void of the compression body is generated. The residual amount of is small, and the usage condition can be significantly improved.

[Effect of device]

As is apparent from the above-described embodiment, the present invention directly compresses metal waste into a compression chamber without using a compression lid opened upward when compressing and deforming the metal waste. In a state where the compression chamber is housed and the compression chamber is opened upward, the compression surface of the side wall and / or the compression surface of the compression member of the lateral compression member can be sufficiently inclined in accordance with the shape of the compression chamber by the reciprocating motion of the lateral compression member. A downward force is generated to compress and deform the waste, and even if a part of the waste protrudes upward from the upper part of the compression chamber, the reciprocating motion of the lateral pushing member causes the waste to be compressed and deformed. It is further advanced, and finally, it is possible to prevent the waste from escaping from the upper part of the compression chamber and form a compression body having a substantially trapezoidal cross section conforming to the shape of the compression chamber. Further, since the compression lid is omitted, the apparatus can be simplified, the extension of the entire cycle time can be prevented, and the processing capacity of the waste compression apparatus can be increased.
