In view of such a situation, the present invention contributes to the empty can recycling system by pressing the empty can volume to a fraction of a size and selecting magnetic cans from non-magnetic cans.

[0002]

2. Description of the Related Art Regarding conventional empty can pressing machines, particularly small machines, there are many manual machines for selecting and loading empty cans. As for a large-sized device, since a hydraulic press device or the like is used, there is a problem that the entire device becomes large. Further, the sorting device for magnetic cans and non-magnetic cans is complicated and oversized.

[0003]

By automatically selecting, transporting and loading empty cans, and pressing the empty cans, the empty cans can be efficiently collected and the safety of people involved can be secured. Even if the apparatus is downsized, the press processing capacity for empty cans can be increased. It is an object of the present invention to provide an apparatus having a large processing capacity per hour by carrying and loading empty cans, pressing them, and discharging and sorting them in parallel.

[0004]

In order to achieve the above object, in the empty can pressing device of the present invention, a storage hopper capable of storing empty cans without sorting is installed at a high place, and a lower part of the storage hopper is installed. Provide a vibration generator. Then, the base is set at a position slightly lower than this, and the following means are taken on this base.

Two blocks are arranged close to each other, and one of them is fixed to a base. Then, an introduction pipe, which is a passage for an empty can, is provided in the center of one fixed block, and a press chamber for pressing the empty can is provided on the left and right of the outlet of the introduction pipe. And
A gate that controls the loading of empty cans is installed near the exit of the introduction pipe. In this way, the introduction pipe, which is the passage of the empty can, is connected to the bottom of the storage hopper.

The other block, which opposes the fixed one block, is constructed so as to be able to move laterally with respect to the introduction pipe. Then, two empty can loading chambers are provided in the other block. The two empty can loading chambers are arranged in parallel with the introduction pipe in the series direction. Then, the press hammers are built in the empty can loading chambers, and the drive parts of the press hammers are fixed behind them. A guide for traversing is provided on the back surface of the other block configured as described above. Then, a rail is provided so as to project from the base, and a traverse guide provided on the back surface of the other block is slidably inserted into the rail. A traverse pneumatic cylinder is arranged on the base, and both ends of the pneumatic cylinder are connected to the base and the other block. When compressed air is supplied to the pneumatic cylinder in this way, the piston rod of the pneumatic cylinder expands and contracts so that the fixed block of the introduction pipe can move laterally in the other block.

A detailed description will be given. As a means for transporting empty cans to the empty can loading chamber, an introduction pipe which is a passage for empty cans is provided at the center of one block fixed to the base. And
The left and right sides of the introduction pipe are broken into a substantially cylindrical shape so that the empty can passing through the introduction pipe can be seen from the outside. Then, a pair of left and right rubber rollers are arranged here. The pair of left and right rubber rollers can be opened and closed so that an empty can passing through the introduction pipe can be directly sandwiched. Further, the pair of left and right rubber rollers is configured to be rotatable by an electric motor or the like, and can transport an empty can to the empty can loading chamber.

As a means different from the above, empty cans can be conveyed in the air. Plural through-holes for floating the empty can are provided near the center lower part of the introduction pipe just before the gate provided near the exit of the introduction pipe. The through hole is formed at a right angle to the center line of the introduction pipe. Then, on the circumference of the introduction pipe before this, a plurality of through holes for transporting empty cans are radially formed from the center, but this through hole is at an angle slightly larger than the right angle to the introduction pipe center line. It is tilted and drilled. Further, the through holes for transportation are formed at positions corresponding to the length of the can type. The empty cans can be floated in the air by blowing compressed air to the empty cans through these through holes. When the gate is opened, the empty cans can be conveyed to the empty can loading chamber in the air.

Two empty can loading chambers are arranged in parallel in the series direction with the introduction pipe in the other block which can be moved laterally to the left and right. A press hammer is built in this empty can loading chamber, and a groove is provided on the end surface of this press hammer. And
A hammer drive unit fixed to the press hammer is fixedly provided behind the press hammer. If the hammer drive is a pneumatic cylinder, supplying compressed air to it will cause the press hammer to move forward, and the empty can will be pinched between the press hammer and the press receiving surface of the press chamber, and then crushed to a minimum. Pressed to size.

The press chambers provided on the left and right of the introduction pipe outlet have a substantially concave cross section. And the lower part is opened and the chute is connected. Further, it has a volume sufficiently larger than the volume of the empty can pressed by the press hammer. The press receiving surface of this press chamber is provided with a groove similar to the groove provided on the end surface of the press hammer, and a magnetic sensor is embedded in the press receiving surface. The lower part of the press chamber is open and a chute through which empty cans can pass is connected. It is not long but the middle of the shoot is branched to the left and right, and a distribution mechanism is installed at this branch point.
At the end of the chute, a stacking basket of empty cans is provided, and a magnetic sensor and a sorting mechanism are controlled via an external control mechanism.
Nonmagnetic cans can be integrated on the other side.

In the above apparatus, the introducing pipe and the empty can loading chamber are connected in series, but these are installed with an appropriate inclination angle with respect to the ground.

[0012]

Function: The vibration generator provided in the lower portion of the storage hopper is activated to slightly vibrate the storage hopper, thereby moving the empty cans that have been unsorted into the storage hopper to the introduction pipe.
The gate provided near the outlet of the introduction pipe is opened and closed vertically by a pneumatic cylinder, etc., the gate is opened and one empty can is passed by the empty can transport mechanism, and after loading the empty can loading chamber, the gate is opened immediately after that. Close. The opening and closing of the gate is controlled to prevent multiple empty cans from being transported to the empty can loading chamber.

In order to convey an empty can from the introduction pipe to the empty can loading chamber, a single or a plurality of empty can conveying mechanisms are provided in the introduction pipe. This empty can transport mechanism has a pair of left and right rubber rollers. Then, the pair of left and right rubber rollers is arranged on a roller base in which the left and right sides of the introduction pipe are broken into a substantially cylindrical shape, and the cylindrical side surface of the empty can is directly sandwiched by the pair of left and right rubber rollers. It is possible to rotate the rubber rollers in directions opposite to each other and convey the empty cans to the empty can loading chamber so as to send them out.

It is also possible to convey empty cans in the air.
That is the next point. A plurality of through holes are formed near the lower center of the gate near the exit of the introduction pipe. The through hole is formed substantially at right angles to the center line of the introduction pipe, and by appropriately adjusting and supplying the compressed air to the through hole, the empty can can be floated almost at the center of the introduction pipe. Further, a plurality of through holes are radially formed from the center on the circumference of the introduction pipe. However, this through hole is formed at an angle slightly larger than the right angle with respect to the center line of the introduction pipe and is inclined in the transport direction of the empty can. After floating the empty can that arrived in front of the gate in the air, blow compressed air toward the can lid or bottom of the empty can. When the gate is opened, empty cans can be transported to the empty can loading chamber in the air.

One block provided with an introduction pipe and a press chamber on the left and right sides thereof is fixed to the base. The other block, which is configured to be movable laterally, has two empty can loading chambers arranged in parallel in the direction in series with the introduction pipe. That is, the empty can is conveyed straight from the introduction pipe and loaded into the empty can loading chamber. Here, the gate provided near the exit of the introduction pipe is opened, and one empty can is loaded into the empty can loading chamber. The other empty can loading chamber is connected in series with one of the press chambers, and is in the process of pressing the empty can loaded in the previous step.

The empty can is loaded in front of a press hammer built in the empty can loading chamber. When the drive unit fixed to the rear of the press hammer is activated, the press hammer moves forward and pushes the empty can toward the press chamber. Although the end surface of the empty can collides with the press receiving surface of the press chamber, the press hammer is moved forward regardless. The empty can is gradually crushed, and at this time, the air in the empty can is discharged to the atmosphere from the drinking mouth, but the drinking mouth is in contact with either of the groove formed on the end surface of the press hammer and the press receiving surface. It is discharged from the groove on the surface. The empty can is then pressed to the minimum size.

The press chambers provided on the left and right of the introduction pipe have a substantially concave shape and have a volume sufficiently larger than the volume of an empty can pressed by a press hammer. The lower part of the press chamber is opened and connected with a chute through which empty cans can pass. The middle of a shot that is not so long is branched, and a distribution mechanism is provided at this branch point. At the end of the chute, a stacking basket of empty cans is provided, and a magnetic can can be stacked on one side and a non-magnetic can on the other.

A magnetic sensor is embedded in the press receiving surface of the press chamber in order to control the distribution mechanism. A control mechanism that amplifies and controls the signal from the magnetic sensor is installed externally to distinguish the empty can from the magnetic can and the non-magnetic can. The empty cans that have been minimized by the above-mentioned squeeze press fall under their own weight to the chute that is opened below the press chamber and connected. The magnetic can and the non-magnetic can can be separately collected by interlocking the sorting mechanism provided in the middle of the chute through the identification function of the magnetic sensor and the external control mechanism.

In the present invention, the introduction pipe for conveying the empty cans and the empty can loading chamber for loading the empty cans are connected in series and installed at an appropriate inclination angle with respect to the ground.

The empty can 4a is sandwiched between the press hammer 18a and the press receiving surface 63 of the press chamber 10a, and is gradually crushed. The pressing process of the empty can 4a is completed by the stroke end of the piston 15a, and the empty can 4a is pressed to the minimum size.

When compressed air is supplied to one of the rod ports 71a (not shown), the piston 15a retracts, and the piston rod 16a fixedly attached to this piston and the press hammer 18a fixed to this end start to retract. The pressed empty can 4a falls under its own weight onto a chute 27a which is opened below the press chamber 10a and is connected to the chute 27a. However, the magnetic sensor 64 embedded in the press receiving surface 63 of the press chamber 10a immediately responds when the empty can 4a pushed out by the press hammer 18a comes into contact with the magnetic can 64 via an external control mechanism (not shown). The non-magnetic can was identified as follows, and the chute 27a (27
The drive motor 29 of the distribution mechanism provided by branching in the middle of b) is activated to switch the damper 28 and separate the magnetic can and the non-magnetic can.

EFFECT OF THE INVENTION A gate provided in the immediate vicinity of the outlet of the introduction pipe and a pair of left and right rubber rollers serve as a mechanism for surely transporting empty cans to the empty can loading chamber one by one. Then, as another means, a plurality of through holes formed near the lower part of the introduction pipe immediately before the gate can float the empty can in the air when compressed air is supplied. Further, the plurality of through holes radially formed from the center on the circumference of the introducing pipe are formed by inclining in the conveying direction of the empty can at an angle slightly larger than a right angle with respect to the center line of the introducing pipe. When compressed air is supplied to the through hole, compressed air is blown toward the center of the can lid or the bottom of the empty can inside the introduction pipe, and the empty can is conveyed to the empty can loading chamber in the air. As described above, in the present invention, the second means is used to convey empty cans. Since one means uses compressed air, empty cans can be transported to the empty can loading chamber in the air very quickly.

Further, according to the present invention, since the introduction pipe which is the passage of the empty can is provided in the center of the fixed block, the press chamber of the empty can can be arranged on the left and right of the introduction pipe. Then, a traverse block configured to traverse movement is provided at a position close to and opposite to the fixed block, and an empty can loading chamber is provided therein in a direction in series with the introduction pipe.
Another empty can loading chamber was arranged in parallel. In the present invention thus configured, one of the empty can loading chambers is connected in series with the introduction pipe by moving the transverse block laterally to the left and right around the introduction pipe, and at the same time, the other empty can loading chamber is connected to the press chamber. Can be connected in series. Also, by expanding and contracting the traverse cylinder, one empty can loading chamber is connected in series with one press chamber, and the other empty can loading chamber is connected in series with the introduction pipe. As described above, the process is always performed in parallel.

The empty cans are conveyed to the empty can loading chamber through the introduction pipe by the empty can conveying mechanism. Even during this conveying process, the empty cans loaded in the other empty can loading chamber are
As the press hammer moves forward, it is pinched and crushed by the press receiving surface of the press chamber. At this time, the air in the empty can is discharged to the atmosphere through the drinking opening provided on the can lid. However, when the end surface of the press hammer or the press receiving surface and the outer edge of the can lid are in flat contact with each other, the air in the empty can is not easily discharged to the atmosphere. Naturally, the thrust for pressing the empty can increases, and therefore the power unit becomes large, which is uneconomical. Therefore, according to the present invention, a groove having a semicircular cross section is provided longitudinally and laterally on the press hammer and the press receiving surface, and the air ejected when the empty can is pressed is allowed to escape from the groove to the atmosphere, whereby the press thrust can be reduced.
Therefore, the device can be made compact and the manufacturing cost can be reduced.

The magnetic sensor embedded in the press receiving surface of the press chamber can discriminate whether the empty can is a magnetic can or a non-magnetic can at the moment of contact with the empty can. Therefore, it is possible to switch the damper provided in the middle of the chute before the empty can is completely pressed. As described above, since the present invention employs extremely simple means, it is possible to provide a maintenance-free device with few failures.

The introduction pipe provided in the center of the fixed block and the empty can loading chamber arranged in the transverse block are connected in series. And these are installed with an appropriate inclination angle with the ground. Since the present invention has such a feature, the empty can will drop by its own weight so as to slide in the inclined introduction pipe even with a slight vibration caused by the vibration generator provided in the lower portion of the storage hopper. Therefore, since natural force acts on the empty can, there is an advantage that a small amount of power is required to load the empty can into the empty can loading chamber.
