DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for compressing and cutting aluminum cans and the like, which simultaneously compresses and cuts the collected aluminum cans into strips.

[0002]

2. Description of the Related Art Conventionally, as means for transporting used aluminum cans that have been collected and used, means for transporting the cans in a container (so-called loose pile) is usually employed. However, this method has a problem that the method is bulky and requires a lot of trouble for transportation. For this reason, it is compressed (so-called press can)
Means of transporting as a lump have been attempted.

[0003]

However, this press can requires a press using a high-pressure hydraulic device. This is problematic in that it is expensive and requires time and effort for maintenance and repair. SUMMARY OF THE INVENTION In view of the above problems , an object of the present invention is to simultaneously compress and cut an aluminum can with one device.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, a compression breaking device for an aluminum can or the like according to the present invention comprises: a rotary blade having a number of rotary cutting blades and collars alternately mounted; The pressure of an aluminum can or the like with a fixed blade
In the compression cutting device, the rotary cutting blade is provided with a number of cutting blades in the circumferential direction, the fixed blade is mounted obliquely, is formed in a comb shape, and the protruding portion has a length reaching the collar inserted between the cutting blades. has is, the outer periphery of the collar is formed in a sawtooth, gripping quality single bite the cans by the cutting blade of the rotary blade, and cut into strips as well as a result compressed to the fixed blade, color
Slide down along the comb blade of the fixed blade installed at an angle
Locks the cut piece and compresses it downwards as the collar rotates.
It is characterized in that it is released .

The apparatus for compressing and cutting an aluminum can or the like (hereinafter simply referred to as an aluminum can) of the present invention having the above-described structure cuts into an aluminum can by the rotation of a rotary blade, compresses it with a fixed blade, and then cuts it into strips.

Then, it slides down along the comb blade of the fixed blade.
Lock and compress the cut piece and release it downward as the collar rotates.
To prevent the fragments from remaining.

[0007]

1 shows an embodiment of the present invention. A compression cutting device 1 such as an aluminum can is rotatably supported in a housing 2 which is open up and down and has a large number of rotary cutting blades. 4
And a collar 5 are alternately mounted on a support shaft 6, and a fixed blade 7 provided opposite the cutting blade 4. The fixed blade 7 is inclined toward the rotary blade 3 to form a comb blade, and the protruding comb blade 7a is inserted between the rotary cutting blades 4, that is, to the position facing the collar 5 and reaches the collar 5. A fixed shearing blade 8 is mounted at an appropriate position on the upper surface, and a fixed compression blade 9 is mounted on the upper surface of the concave portion facing the rotary cutting blade 4.

The rotary cutting blade 4 is provided with a large number of cutting blades 4a (five in the example in the figure) projecting in the circumferential direction, and is appropriately scooped so that the can W is bittenly gripped by the cutting blades 4a by the rotation of the rotary blade 3. The fixed shearing blade 8 is shaped like scissors so as to perform a shearing action on the can W. Further, it is preferable that the mounting positions are sequentially shifted so that the cutting blades 4a of the parallel cutting blades 4 are not straight but inclined in the axial direction. The fixed compression blade 9 is opposed to the tip of the cutting blade 4a of the rotary cutting blade 4 with a small gap, and performs compression and shearing of cans by the rotary cutting blade 4. Further, when the fixed blade 7 is made of a wear-resistant material having a required hardness, it is not always necessary to attach the fixed shear blade 8 and the fixed compression blade 9, and these blades are worn by a long use. It is installed in an easy place, and has the effect of increasing durability by replacement.

[0009] The collar 5 has cut-piece locking irregularities 5a formed on the outer periphery. The unevenness is preferably in the form of a saw blade, so that the cut piece that slides down along the comb blade is locked and compressed, and is released downward by rotation. In the drawing, reference numeral 10 denotes a cover plate inserted on the opposite side of the fixed blade 7 and between the rotary cutting blades 4, M denotes a rotary blade drive motor, and G denotes a speed reducer.

The operation of the above arrangement will be described with reference to FIG. The supplied can W moves to the rotary blade 3 side along the inclination of the fixed blade 7, and the cutting blade 4 a of the rotary cutting blade 4 bites into this, and with the rotation, the fixed compression blade 9
Thus, the can W is first compressed (FIG. 4). As the rotation further proceeds, the rotating cutting blade 4 and the fixed shearing blade 8 compress and shear one side of the can W into a comb blade shape by a shearing action. FIG. 8 shows the condition of the sheared can Wb, and FIG. 9 shows the short cut piece b. However, FIG. 2 shows a case where the diameter of the supplied can W is larger than the height h of the cutting blade 4a. When the diameter is smaller than the height h, the fixed blade 7 is compressed by the protruding portion of the comb blade 7a, and cut by the rotation of the rotary blade.

Then, as the cutting blade 4a rotates, the can W
b becomes free and moves along the comb blade 7a of the fixed blade 7 by its own weight, stops at the position where it reaches the cutting blade 4a, is cut in the above-described manner, and the short cut piece b cut off by the cutting blade 4a falls. The long cut piece a on the comb blade 7a slides down on the comb blade 7a to reach the collar 5, and the collar 5
Is fed downward with the rotation of. In the case of a still larger diameter can, the above-described cutting procedure is repeated.

Although the case where the can W is supplied in parallel with the rotary blade 3 has been described above, even when the can is supplied at a right angle, it is similarly cut into strips. However, in this case, the cut piece a is longer than the illustrated example,
In any case, the bulk is reduced, and the amount of storage in the container can be increased.

[0013]

As described above, according to the present invention, cans to be supplied can be cut into strips at the same time as compression, so that cans having a large volume can be reduced. Can be stored and transported.
In addition , the cutting piece that slides down along the fixed
Shrink and release downward as the collar rotates
And pull out the remaining pieces on the fixed blade to remove the remaining fragments.
Can be prevented.
