Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for flattening or flattening a cylindrical body such as a can which is no longer needed by crushing it.

[0002]

2. Description of the Related Art Used beverage cans and cans that have become defective in the manufacturing process are discarded as garbage and reused. , A small number will occupy a large space. Therefore, conventionally, in order to improve the stock efficiency and the transportation efficiency of these cans, the cans that have become unnecessary are crushed to reduce the volume as much as possible. As a simple device for crushing a can, a manual or foot-operated device using a lever is known, and a press-type device equipped with a drive device is known.

[0003]

[Problems to be Solved by the Invention] Although a crusher such as a manual type or a foot-operated type crusher is effective in installing it near a source of unnecessary cans such as a place where canned beverages are consumed, it is a waste treatment facility. In the case of handling a large amount of unnecessary cans such as in a can manufacturing factory and the like, a processing capacity is insufficient, and therefore, a device equipped with a drive device such as a press type is excellent for large-scale processing. However, since the press-type crusher crushes in a predetermined chamber, it requires a discharge device for discharging the crushed cans from the chamber, and it is inevitable that it is a so-called batch process. It is necessary to take timing with the drive of the press. Therefore, the press-type crusher has a problem that the size of the device is increased as a whole or the control device is complicated.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a device capable of continuously and reliably crushing a cylindrical body such as a can and reducing the size thereof. To do.

[0006]

[Operation] In this invention, they are diagonally adjacent to each other in the vertical direction.
The rollers are rotated in opposite directions. That rotation
Is a rotation in which the ridges attached to the outer peripheral surface of each roller oppose each other on a straight line connecting the centers of the adjacent rollers , and move downward from the opposing position. When the ridge of one roller is caught on the cylindrical body dropped from above between the rollers, the ridge of the other roller is also caught on the cylindrical body. So the cylinder is
These ridges push the rollers into place without rotating or being knocked out between them. Since the distance between the outer peripheral surfaces of the rollers is smaller than the outer diameter of the cylinder, the cylinder is crushed while passing between the rollers .
Also, in the unlikely event that the roller is not crushed smoothly,
Even if there is a cylinder body that is repelled, the cylinder

It is embedded and crushed. That is, the circles on the outside of both rollers
Accidents that would cause the cylinder to come off greatly will be prevented.

[0007]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a layout view of rollers in an embodiment of the present invention. In the example shown here, a can 1 which is an object to be crushed.
Is crushed by four rollers 2, 3, 4, 5.

The first of these rollers 2, 3, 4, 5
As shown schematically in FIG. 2, the roller 2 has a plurality of ridges 6 having a height corresponding to the outer diameter of the target can 1 and an axial line on the outer peripheral surface at a pitch p corresponding to the outer diameter of the can 1. It is formed in parallel with the direction, and is laid out in a substantially horizontal manner by rotatably supporting both ends of the rotary shaft 7 by bearings 9 attached to the machine frame 8. Further, the second roller 3 has its rotary shaft 1 mounted diagonally above the above-mentioned first roller 2 (obliquely above left in FIG. 1).
0 is rotatably supported by a bearing 11 attached to the machine frame 8 and is arranged parallel to the first roller 2.
The minimum width between the outer peripheral surfaces of the first and second rollers 2 and 3 is set narrower depending on the outer diameter of the can 1.
Further, on the outer peripheral surface of the second roller 3, as in the case of the first roller 2, a plurality of ridges 12 having a height corresponding to the outer diameter of the can 1 are provided.
It is formed at the same pitch as the pitch p of the protrusions 6 on the roller 2.

Below the second roller 3, a third roller 4 rotatably supporting both ends of a rotary shaft 14 by a bearing 13 attached to a machine frame 8 is arranged substantially horizontally.
The third roller 4 is for further crushing the can 1 already crushed to some extent by the first roller 2 and the second roller 3 between the first roller 2 and the first roller 2. The minimum width between the outer peripheral surfaces of the first roller 2 and the second roller 3 is set to be smaller than the minimum width between the outer peripheral surfaces of the first roller 2 and the second roller 3. Also,
In order to improve the biting of the can 1, a plurality of ridges 15 parallel to the axial direction are also formed on the outer peripheral surface of the third roller 4. Further, below the first roller 2, a fourth roller 5 is arranged which is rotatably supported at both ends of a rotary shaft 17 by a bearing 16 attached to the machine frame 8 and is arranged substantially horizontally. The fourth roller 5 is for further crushing the can 1 between the third roller 4 and the third roller 4, and the minimum width between the outer peripheral surfaces of the third and fourth rollers 4 and 5 is It is set to be narrower than the minimum width between the outer peripheral surfaces of the first and third rollers 2 and 4. The outer peripheral surface of the fourth roller 5 has an axial direction in order to reduce interference with the ridges 15 formed on the outer peripheral surface of the third roller 4 or the can 1 deformed by the ridges. A plurality of concave grooves (not shown) are formed at regular intervals.

Rollers 2, 3, 4, arranged as described above
5, a hopper 18 opened from the upper side is provided between the first roller 2 and the second roller 3, and the can 1 put into this
Are dropped between the first roller 2 and the second roller 3.

FIG. 3 shows a drive mechanism for the rollers 2, 3, 4, and 5 described above. The example shown here uses a motor 19 as a drive source, and the motor 19 and the rotation shaft 17 of the fourth roller 5 are connected by a chain 20 and a sprocket (not shown). The rotating shaft 17 of the roller 5, the rotating shaft 7 of the first roller 2, and the second
The rotary shaft 10 of the roller 3 and the rotary shaft 14 of the third roller 4 are connected by another chain 21 and 22 and a sprocket (not shown), respectively. On the other hand, the rotary shaft 7 of the first roller 2 and the rotary shaft 10 of the second roller 3 are connected by a pair of gears 23 and 24 which are attached to each other and mesh with each other. The tooth number ratio of these gears 23, 24 is made to correspond to the ratio of the outer diameter of the first roller 2 and the outer diameter of the second roller 3, and the protrusions formed on the outer peripheral surfaces of these rollers 2, 3 respectively. Articles 6 and 12 are rollers 2,
They are meshed so as to face each other on a straight line connecting the centers of 3. Therefore, the peripheral velocities of the first roller 2 and the second roller 3 are substantially equal to each other, and one of the protrusions 12 of the second roller 3 is always synchronized with the protrusion 6 of the first roller 2. There is. It should be noted that the rotation direction of the motor 19 depends on the rotation shafts 7,
10, 14 and 17 are directions of rotation in the arrow direction of FIG. Further, in FIG. 3, reference numerals 25, 26 and 27 each represent a chain tensioner.

Therefore, in the configuration shown in FIG. 1, between the first roller 2 and the second roller 3 and between the first roller 2 and the third roller 3.
Between the roller 4 and the third roller 4 and the fourth roller 5
The three crushed portions between and are the crushed portions of the can 1, and these crushed portions are arranged in a zigzag order in order from the top, and the can 1 is crushed while being dropped as shown by the arrow in FIG. 1 and discharged from below. It is like this.

Flanges 28 are attached to both ends of the first roller 2 described above. This flange 2
The outer diameter of 8 is set so as to reach substantially both sides of the above-mentioned three crushed portions, as shown by the chain line in FIG. 1, and its flange 28 extends to the end side of the rollers 2, 3, 4, 5. It prevents the can 1 from popping out. Although not particularly shown, the outer periphery of the crusher shown in FIG. 1 is almost entirely covered by the casing except the opening of the hopper 18.

Next, the operation of the above crusher will be described. By starting the motor 19, each roller 2,
3, 4, 5 rotate in the direction of the arrow in FIG.
The roller 2 and the second roller 3 have opposite rotation directions,
Each of the ridges 6 and 12 moves downward at the position of the minimum width that should be the crushed portion. The can 1 loaded from the hopper 18 is guided by the hopper 18 to the first roller 2 and the second roller 2.
A can 1 that was fed between the roller 3 and fell horizontally
Is first fitted between the protrusions 6 of the first roller 2. The space between the rollers 2 and 3 is a space formed by an arcuate surface and is opened upward in a taper shape.
The can 1 that is in contact with the outer peripheral circular surface is held by the ridge 6 of the first roller 2 and is pressed between the first roller 2 and the second roller 3 by the pressing force received from the ridge 6. . On the other hand, the second roller 3 is connected to the first roller 2 via gears 23 and 24 so as to rotate synchronously. Therefore, the second roller 3 is synchronized with the ridge 6 of the first roller 2. Ridge 12
Are moving at almost the same peripheral speed. Therefore, the can 1 held by the ridge 6 of the first roller 2 is not
2 acts so as to press down from the upper side, so that the can 1 is forcibly pushed between the rollers 2 and 3 which are the crushing portions by the ridges 6 and 12 of the rollers 2 and 3, and the can 1 is crushed. Be done.

The cans 1 fed from the hopper 18 between the first roller 2 and the second roller 3 are mixed in various directions and are not always horizontally fallen, but other than the horizontally fallen cans 1. The edges of both ends of the can 1 are hooked on the surfaces of the rollers 2 and 3 and the ridges 6 and 12, and are pushed between the rollers 2 and 3 by the force generated at that portion . Example here
If this happens, the first roller 2 and the
While dancing with the two rollers 3, is it the center side of both rollers 2, 3?
Even if there is a can 1 that moves toward the end from the
The inner surface of the flange 28 bounces off the rollers 2, 3
Returned to the upper side. After all, the can 1 has the ridges 6, 1
It is hooked on 2 and pushed into the crushed part. as a result,
Be crushed.

The can 1 deformed by being crushed between the first roller 2 and the second roller 3 is pushed downward as the rollers 2 and 3 rotate, and then the first roller 2 and the second roller 3 are rotated. It is caught between the roller 3 and the roller 3. In that case, since the can 1 is deformed to a flat shape to some extent, these rollers 2,
Between the rollers 4, even if it is difficult to bite due to the crushed shape and the feeding posture, the ridges 6, 15 formed on the outer circumference of the rollers 2, 4 can Since they can be caught by 1, the cans 1 are pushed between the rollers 2 and 4 and crushed. Since the space between the first roller 2 and the third roller 4 is narrower than the space between the first roller 2 and the second roller 3, the can 1 is further flattened and crushed, and from there, the third roller 4 is pressed. And the fourth roller 5. Finally, the sheet is further crushed by the third roller 4 and the fourth roller 5 and discharged below. Even when the can 1 is bitten between the third roller 4 and the fourth roller 5, the can 1 is caught in the protrusion 15 of the third roller 4 or the groove of the fourth roller 5, and the can 1 Is quickly caught between the rollers 4 and 5 and crushed.

When the can 1 is crushed at the above-mentioned three places, it becomes thin locally or is broken to form a thin projection, and these thin parts may get caught in some gaps and get caught. However, in the above-described device, the flanges 28 attached to both ends of the first roller 2
Since the side portions of the above-mentioned three crushed portions are almost completely covered, the gaps that may bite the thin portion of the crushed can 1 are reduced, and as a result, a large number of cans 1 can be smoothly and continuously connected. You can crush it.

In the above-mentioned apparatus, the four rollers are vertically displaced from each other and are arranged in a zigzag manner, so that the apparatus can have a crushing portion at three positions. Therefore, the can can be crushed to a considerably thin thickness in one step. You can However, the present invention is not limited to the embodiment shown in the drawings, and may have a configuration in which only a pair of rollers, a first roller and a second roller, are provided, and in that case, those rollers are vertically arranged. No need to shift. Further, the present invention is not limited to a can, but can be applied to a device for crushing a wide range of general cylindrical bodies such as bottles. Further, although the chain and the gear are used for transmitting the torque in the above-described embodiment, the drive mechanism of the present invention may be any mechanism that can reliably transmit the torque. It is not limited to one.

[0019]

As is apparent from the above description, according to the present invention, since the cylindrical body is caught and crushed between the rollers, continuous and automatic crushing and discharging can be performed. In addition, it is possible to reduce the size of the device and eliminate the need for special control. On the outer periphery of each roller was or
