Abstract

PURPOSE: To perform an operation by a device with the cutting-off working of the top and the bottom of a waste can and a compression press integrated. CONSTITUTION: A pair of cutting blades 8 cutting off the top plate and the bottom plate of a waste can, is provided symmetrically to the right and the left. And, after cutting off the top plate Wa and the bottom plate Wb of the waste can W by the cutting blade 8, which is supplied sideways, the side surface Wc of the waste can W is compressed from an upside by a compression plate 6 mounted on a cylinder 7, and is pressed to a flat plate shape. Since a process cutting the top and the bottom of the waste can and a compression process are set to a series of processes with one device, contamination by waste liquid in a site is prevented. Also, after cutting off the top plate and the bottom plate of the waste can, since the waste can is compressed from a side surface, a pressure force necessary for compression becomes small. At the same time, the waste can be made to a sheet, and capacity reducing efficiency is very high.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for compressing waste cans such as one-tower cans, pail cans, and drum cans into flat plates.

[0002]

2. Description of the Related Art Conventionally, as a method for compressing waste drums, there is a technique disclosed in Japanese Utility Model Laid-Open No. 5-70792. According to such a method, a drum can or the like is compressed from the ceiling portion with the pressing force of the cylinder from the ceiling with the top and bottom facing up and down.

There is also a method of cutting the top and bottom of a waste can in a separate process before performing compression pressing, but this requires a lot of work and the waste liquid remaining inside the waste can flows out at the time of cutting. There was a problem.

[0004]

When the above method is used,
Since the drum or the like is compressed in the vertical direction, it is necessary to increase the pressing force required for compression, the compression cylinder has a large diameter, and the hydraulic source for operation also needs to have a high pressure specification. Further, when the waste cans are compressed in the vertical direction, they are not completely plate-shaped and the volume reduction rate is low. In view of these points, the present invention provides a pressing method and a device thereof that can compress waste cans into a flat plate shape to improve volume reduction efficiency and save energy, and prevent leakage of residual waste oil. With the goal.

[0005]

A method for pressing a waste can according to a first aspect of the invention for achieving the above object is to provide a pair of cutting blades for cutting a top plate and a bottom plate of a waste can on left and right sides, and supply them sideways. The gist of the invention is to cut the top plate and bottom plate of the waste can with the cutting blade, and then compress the side surface of the waste can from above with a compression plate attached to a cylinder to press it into a flat plate shape. .

A second aspect of the present invention relates to a waste can pressing apparatus for carrying out the above method, and in a waste can pressing apparatus for compressing a can by pressing force of a cylinder from above, the upper part of the frame is connected to a compression cylinder. And a pair of cutting blades for cutting the top plate and the bottom plate of the waste can on the left and right side parts of the frame body, and the cutting plate of the can top plate and the bottom plate are advanced by advancing the cutting blades. The gist of the present invention is to sequentially perform cutting and compression of the waste can side portion by a compression plate provided above.

[0007]

[Operation] By cutting off the bottom plate of the waste cans, it becomes easy to compress the side parts of the waste cans by a compression board and press them into a flat plate.

[0008]

[Examples] The figures show examples of the present invention. The waste can press device 1 includes a frame body 2 composed of a top plate 3, side walls 4, and a floor plate 5, the front and rear of which are open, a compression cylinder 7 attached to the top plate 3 for raising and lowering a compression platen 6, and side walls. 4 is provided with a punching cylinder 9 for advancing and retracting left and right cutting blades 8 for cutting the top plate Wa and the bottom plate Wb of the waste cans W. A large number of waste liquid holes 10 are formed in the floor plate 5 so that when the top and bottom of the waste cans are cut, the waste liquid and the like remaining inside the waste cans flow out to the inclined plate 11 provided below, and the inclined plate 11 allows the waste liquid reservoir to be collected. (Not shown). Reference numeral 12 denotes a fixing member for waste cans, which is preferably made of an elastic member such as rubber or sponge so as to absorb the pressing force of the compression platen 6. Note that FIG. 5 shows, as an example, a fixing member for a rectangular parallelepiped waste can such as a one-tower can.

As the cutting blade 8 for cutting the top plate Wa and the bottom plate Wb of the waste cans W, as shown in FIGS. 3 to 4, a cutting blade having an appropriate structure is selected and used according to the shape of the waste can. FIG. 3 shows a cylindrical waste can such as a pail can and a drum can. The cutting blade 8a is formed on a cylindrical body portion 13a and a tip thereof corresponding to the shapes of the top plate and the bottom plate of the waste can. And a saw blade-shaped cutting portion 13b. For a rectangular parallelepiped waste can such as an Ito can, the cutting blade 8b shown in FIG. 4 is used. The cutting blade 8b is similarly composed of a prismatic body portion 14a that conforms to the shapes of the top plate and the bottom plate, and a saw blade-shaped cutting portion 14b formed at the tip thereof. Both cutting blades are designed to cut the top plate and the bottom plate by pushing them.

Reference numeral 15 denotes a line sensor attached to the left and right side walls 4, which detects when a worker's limb or the like enters the apparatus during work and stops the operation thereof.

In the above structure, the waste canister W is laterally fed and placed on the fixing member 12, and the left and right punching cylinders 9 (columnar waste canister in the figure) are simultaneously operated toward the inside of the apparatus, After cutting the top plate Wa and the bottom plate Wb of the waste can W by the cutting blade 8, the cut top plate Wa and the bottom plate W are cut.
The cylinder 9 is retracted to the original position while leaving b inside the waste can W. After that, the compression platen 6 is lowered by the compression cylinder 7, and the side surface Wc of the waste can W is compressed and pressed. After a while
The compression platen 6 is raised to its original position, and a waste can compressed into a sheet by a proper means is taken out from the apparatus by a proper means.

The cutting blades 8 on the top plate and the bottom plate are cutting blades which are cut by being pushed in by a cylinder, but a rotating cutting blade may be used when the waste can is a column.

[0013]

As described above, according to the present invention, the step of cutting the top and bottom of the waste cans and the step of compressing are made into a series of steps by one device, so that the contamination of the site by the waste liquid is prevented. . Also, since the top and bottom plates of the waste can are cut off and then compressed from the side surface, the pressing force required for compression is small and it is possible to save power consumption. Since it can be made into a sheet shape, the volume reduction efficiency is extremely high. Furthermore, it can be applied to various waste cans by appropriately replacing the fixing member and the cutting blade.
