A fixed body having a surface portion, and a compression surface portion disposed along the vertical direction in the apparatus main body and having a lower end portion pivotally supported by a pivot and facing a compression surface portion of the fixed body, and the compression surface portion is provided on the compression surface portion of the fixed body. A movable pressing body that swings between a position where the empty can is compressed together with the fixed body and a position separated from the compression surface portion of the fixed body, and a driving device that swings and drives the movable pressing body. There is. The compression surface of the fixed body and the compression surface of the movable pressing body are made of a hard material in consideration of compressing the empty can.

[0003] In this empty-can compression device, when waiting for an empty can to be inserted from an input port of the device body, the movable pressing member is located at a position separated from the compression surface portion of the fixed member, and the movable pressing member is in contact with the movable pressing member. The fixed body is opened toward the upper end with the lower ends of both being centered to form a V-shaped space. When the empty can is inserted from the inlet of the apparatus main body, the empty can enters the V-shaped space formed by the movable pressing body and the fixed body from its upper end and descends along the compression surface of the fixed body. When the empty can is inserted from the charging port, the movable pressing body is swung about the pivot axis toward the position approaching the fixed body by the driving device to close the V-shaped space. As a result, the empty can is pressed by the compression surface of the movable pressing member, pressed against the compression surface of the fixed member, and compressed by the movable pressing member and the fixed member. Thereafter, the movable pressing body is swung again around the center toward the separated position by the driving device, and the space between the movable pressing body and the fixed body is opened, and the compressed empty can falls from between the movable pressing body and the fixed body.

As shown in FIG. 1 and FIG. 3, a horizontally long slot 4 is formed in the upper part of the front of the apparatus body 1 facing the processing section 2, and the inside of the apparatus body 1 is combined with the slot 4. An input port body 5 is provided. The charging port body 5 is rotatably supported on a side wall 52 by a horizontal shaft 6 provided at a lower part of the side surface, and is vertically upright and forwardly inclined toward a position where the charging port 4 is closed. It can rotate between the position where the mouth 4 is opened. Normally, the center of gravity is set so that the charging port body 5 is in the closed position, and the input port 4 is opened when a force is applied so as to be pulled down toward the outside of the main body and turned toward the open position on the outside. The inside of the charging port 5 receives an empty can V as a lightweight article and an empty bottle W as a heavy article.

That is, the charging port body 5 is turned to the open position outside the main body to open the charging port 4, and the empty can V or the empty bottle W is placed inside the charging port body 5. Next, when the charging port body 5 is rotated to the closing position, the empty can V or the empty bottle W placed on the charging port body 5 is transported to the inside of the apparatus main body 1 and falls from the charging port body 5.

In the figure, reference numeral 7 denotes a horizontally long shutter having the same size as the input port body 5. The shutter 7 is supported by a horizontal shaft 8 provided on a side wall 52 and has a shielding position which hangs down and an open position where it is swung up. It is designed to rotate between. Reference numeral 9 denotes an elastic body that connects the shutter 7 and the input port body 5, for example, a coil spring 9

That is, the lever 10 enables the shutter 7 to rotate from the open position to the closed position when the input port 5 rotates from the closed position to the open position, and the input port 5 closes from the open position. When the shutter 7 is turned to the formation position, the shutter 7 is turned from the shielding position to the open position. Thus, the shutter 7 is in the blocking position when the input port body 5 is in the open position, and the input port 4 of the apparatus main body 1 is closed to prevent a hand or the like from being put into the apparatus main body 1.

As shown in FIG. 1 and FIG. 3, an empty can V
Alternatively, a seesaw-shaped weight sorter 13 is provided as an example of a weight sorter that receives an empty bottle W and sorts by weight discrimination. The horizontally long weight selector 13 is disposed below the input port 5, and a portion close to the input port 5 has a shaft 6 provided on the side wall 52.
The solid position 13A, which is supported by a horizontal shaft 14 parallel to and receives the empty can V or empty bottle W inserted from the charging opening body 5 in FIG. It turns between the downward position 13B shown.

A weight 15 is attached to an end of the weight selector 13 close to the input port 5, and the weight selector 13 is rotated clockwise by a stopper (not shown) provided on the apparatus main body 1. Has been blocked. For this reason, the weight sorter 13 is always stopped at the steady position 13A inclined downward from the charging port body 5 toward the compression device 16 to be described later by the action of the weight 15 and the stopper. The empty cans V and empty bottles W that have been loaded are lowered.

When the weight of the article to be received is 80 g, the weight selection body 13 is used as a reference point for operation. The empty can V is guided to the compression device 16 while being stopped at the position. Further, when the weight sorter 13 receives the empty bottle W having a weight of 80 g or more inserted from the input port body 5, the weight sorter 13 moves downward from the steady position 13A to the downward position 13B against the weight of the weight 15 by its weight. Rotate.
The empty bottle W separates from the weight sorter 13 and falls,
From the collection box 3 provided in the collection unit 3 into the empty bottle storage unit 32. In this manner, the weight of the empty bottle W is determined, and the empty bottle W is sorted and recovered from the empty can V.

After the empty bottle W falls, the weight sorter 1
3 rotates to the steady position 13A by acting on the weight 15.

In FIGS. 1 and 4, reference numeral 16 denotes a compression device. The compression device 16 is provided inside the apparatus main body 1 at an obliquely lower side with respect to the end of the weight sorter 13 on the empty can drop side. The compression device 16 is a vertically long fixed body 17 arranged vertically along the vertical direction and fixed to the side wall 52, and faces the fixed body 17 at a position opposite to the weight sorting body 13 with respect to the fixed body 17. And a horizontally-long movable pressing body 18 supported by a pivot 19 provided on a side wall 52 so as to be swingable with its lower end as a fulcrum.

On the other hand, the fixed body 17 serves as a partition for guiding the empty bottle W dropped from the weight sorting body 13 to the empty bottle collecting section 32 of the collection box 31, and on the other hand, the empty bottle W dropped from the weight sorting body 13. It has a role of partitioning the can V to the empty can collection portion 33 of the collection box 31 and a role of compressing the empty can V together with the movable pressing body 18. The fixed body 17 is in the form of a plate made of a hard material such as a metal, for example.
It has been. A number of convex portions are formed on the compression surface portion 17a. In this embodiment, a large number of ridges 17b having a triangular cross section extending in the horizontal direction are formed on the compression surface 17a.
Are formed side by side in the vertical direction. In addition, the fixed body 17
Side plates 17c are provided on both side edges in the length direction toward the movable pressing body 18, respectively. This is to prevent the empty can V from moving laterally and dropping. In FIG. 1, the movable pressing member 18 has a plate shape formed of a hard material such as a metal. Fixed body 17 in this movable pressing body 18
A compression surface body (compression surface portion) 180 is attached to a surface facing the compression surface portion 17a. This compression plane 180
Is a substrate 181 formed of a hard material such as a metal.
And a flat sheet-shaped compression face plate 182 formed of an elastic synthetic resin such as urethane rubber or the like and bonded to the substrate 181, and other elastic materials. Here, the material having elasticity means that the material is pressed by the empty can and immerses to press the empty can and, after the empty can is removed, is restored to its original state by elasticity. The substrate 181 is attached to the movable pressing body 18 by, for example, screwing so as to facilitate replacement. That is, the movable pressing member 18 has a compression surface portion made of the above-described elastic material facing the compression surface portion 17a of the fixed body 17.

The movable pressing member 18 is moved from the position 18A farthest from the fixed member 17 to the fixed member 17 indicated by a chain line.
Where the empty can V is pressed against the fixed body 17 closest to
8B around the pivot 19. That is, when the movable pressing body 18 is at the separated position 18A, the V-shaped space portion X is opened between the movable pressing body 18 and the fixed body 17 centering on the lower ends thereof and moving toward the upper end. The left and right width dimensions of the movable pressing body 18 are large enough to enter the inside of the pair of side plates 17c and swing.

In FIGS. 1 and 4, reference numeral 20 denotes a drive unit, which is provided inside the apparatus main body 1 adjacent to the compression unit 16. The driving device 20 includes an electric motor 21 and a side wall 52 parallel to the pivot 19 of the movable pressing body 18.
, A cam 23 attached to the rotating shaft 22, and a cam follower 24 attached to the upper end of the movable pressing body 18 and in contact with the outer peripheral surface of the cam 23.

The rotation shaft 22 is provided on the side wall 52.
The cams 23 are mounted as a pair at locations spaced apart in the axial direction as shown in FIGS. The cam followers 24 are arranged in a pair at the upper end of the side surface of the drive unit of the movable pressing body 18 facing the pair of cams 23 and are rotatably supported by the movable pressing body 18.

The rotation of the electric motor 21 is performed via a pulley 25 attached to the output shaft of the electric motor 21, a pulley 26 attached to the rotary shaft 22, and a belt 27 wound around the pulley 25 and the pulley 26. 22. As shown in FIG. 4, a pressure is applied to the movable pressing member 18 by a tension coil spring 28 which is an example of an urging member so that the cam follower 24 is always in contact with the outer peripheral surface of the cam 23.

The shape of the cam 23 is such that when the cam 23 is at the initial position shown in FIG. 1, the movable pressing body 18 is tilted to the separated position 18A with respect to the fixed body 17 and the empty can V is On the way to pass between the movable pressing body 18 and the
Is swung to the approach position 18B to press and compress the empty can V. The apparatus body 1 has an input port 5
Is provided with a drive switch (not shown) that is operated by rotating from the open position to the closed position to drive the electric motor 21.

That is, the movable pressing member 18 is moved to the separated position 18
Waiting for empty cans at A. When the loading port body 5 is opened and the articles are placed and then returned from the open position to the closed position, the articles are thrown into the weight sorter 13 and the drive switch operates to start the electric motor 21. Input port 5
Is empty can V, the empty can V falls from the weight sorting body 13 and descends between the stationary body 17 and the movable pressing body 18 which are waiting. When the electric motor 21 is driven to rotate, the rotation is transmitted to the rotating shaft 22 and the rotating shaft 22 is rotated.
At the same time, the cam 23 rotates in the direction of the arrow shown in FIG.

When the cam 23 rotates, the cam follower 24 moves in a direction in which the tip of the movable pressing member 18 approaches the fixed member 17. When the cam 23 rotates by a predetermined angle and reaches the approaching position 18B approaching the fixed body 17, the movable pressing body 18 becomes almost upright with respect to the fixed body 17, and the movable pressing body 18 and the fixed body 17 Is pressed and compressed by the movable pressing member 18 and the fixed member 17. Thereafter, as the cam 23 rotates, the cam follower 24 moves the movable pressing body 18.
Is moved in a direction away from the fixed body 17, and the rotation of the cam 23 causes the movable pressing body 18 to reach the separated position 18A and return to the initial state. The electric motor 21 stops when the cam 23 makes one rotation.

Further explanation will be given. When waiting for the empty can V to be inserted from the input port of the apparatus body 1, the movable pressing member 18 is located at a position 18A separated from the compression surface portion 17b of the fixed member 17, and the movable pressing member 18 and the fixed member 17 Are opened toward the upper end with the lower ends of both as the center, forming a V-shaped space portion X. As shown in FIGS. 6 and 7, when the empty can V is inserted from the input port of the apparatus main body 1,
The empty can V is a V formed by the movable pressing body 18 and the fixed body 17.
It enters into the character-shaped space portion X from its upper end and descends along the compression surface portion 17a of the fixed body 17. The position 18B at which the movable pressing body 18 approaches the fixed body 17 by the driving device 20
To swing around the pivot 19 to close the V-shaped space X. As a result, as shown in FIG. 8, the empty can V is pushed by the compression face plate 182 of the compression face body 180 of the movable pressing body 18 and pressed against the compression surface portion 17a of the fixed body 17, and is sandwiched between the movable pressing body 18 and the fixed body 17. Compressed.

Here, as shown in FIGS. 6 and 7, the movable pressing member 18 is a substrate 1 made of a hard material for the compression surface member 180.
The empty can V is pressed by the compression face plate 182 via 81. Then, the compression face plate 182 is pushed by the empty can V and is immersed by elasticity, and a part of the compression face plate 182 comes into pressure contact along the peripheral surface of the empty can V. The portion of the compression face plate 182 which is immersed and pressed against the peripheral surface of the empty can V is pressed in the direction in which the empty can V is pushed away from the swing fulcrum (the pivot 19) of the movable pressing body 18 by pressing the empty can V, that is, the upper side. It is a resistance that prevents the robot from moving upward. Then, the movable pressing body 18 is fixed to the fixed body 1.
7, a force is applied to the empty can V in a direction away from the pivot (the pivot 19) of the movable pressing body 18, but the compression face plate 182 acts as a resistance and the empty can V
Are prevented from moving in said direction. Also, since a large number of ridges 17b are formed on the compression surface portion 17a of the fixed body 17 in a horizontal direction, that is, in a direction that hinders the movement of the empty can V, a large number of ridges of the fixed body 17 are formed. 1
7b also prevents the empty can V from moving in a direction away from the pivot (the pivot 19) of the movable pressing body 18. Accordingly, even if the empty can V is subjected to a force directed in a direction away from the pivot (the pivot 19) of the movable pressing body 18, it can be prevented from moving upward and floating. Furthermore, empty can V
Is pressed at a position close to the swing fulcrum (the pivot 19) of the movable pressing body 18, so that it can be pressed with a smaller force than when it is pushed away from the swing fulcrum (the pivot 19). The load on the electric motor 21 of the driving device 2 at the time can be reduced.

Then, the movable pressing body 1 is driven by the driving device 20.
8 is again swung toward the inclined separating position 18A to open between the movable pressing body 18 and the fixed body 17, and the compressed empty can V slides on the surface of the compressed surface body 18b of the inclined movable pressing body 18. And the movable pressing body 18 and the fixed body 17
And falls into the empty can storage section 33 of the collection box 31 provided in the collection section 3 of the apparatus main body 1.

As described above, in the driving device 20, when an article is put in, the cam 23 is rotated once by the electric motor 21 to cause the movable pressing body 18 of the compression device 16 to swing one reciprocating motion to compress the empty can V.

In this embodiment, since the compressed surface body 18b made of an elastic material of the movable pressing body 18 has a flat sheet shape (because the ridges are not formed side by side), the compressed empty can V is It can smoothly slide on the surface of the flat compression surface body 18b and fall. Also, a large number of ridges 17
Since b is formed on the compression surface portion 17a of the rigid fixed body 17, when foreign matter other than the empty can V enters between the fixed body 17 and the movable pressing body 18, a large number of ridges are formed by the foreign matter. 17b is not damaged.

It is also possible to provide a compression body made of an elastic material on the fixed body, and to form a large number of ridges on the compression surface of the movable pressing body made of a hard material. What is formed in order to prevent floating of the empty can on the compression surface of the fixed body or the movable pressing body made of a hard material is not limited to a large number of ridges,
For example, a large number of small projections may be used. In short, it is sufficient that a large number of projections for preventing floating are formed.

The inside of the collection box 31 provided in the collection section 3 of the apparatus main body 1 has an open upper surface and is partitioned into an empty bottle storage section 32 and an empty can storage section 33.

In FIG. 1, reference numeral 29 denotes a horizontally long bottle guide provided at the lower end of the fixed body 17, which is bent in an L-shape. The bottle guide body 29 guides the empty bottle W, which has been sorted by the weight sorter 13 and falls along the fixed body 17, to the empty bottle accommodating portion 32 inside the collection box 31, and also receives an impact due to the drop of the empty bottle W. It is alleviating. The bent portion 29a of the bottle guide body 29 is formed in an arc so as not to be clogged when the empty bottle W falls. 30 is the bottle guide 2
9 is a partition provided on the lower side.

In FIG. 1, reference numeral 34 denotes an elimination body formed as a projection protruding downward on the side surface of the charging port body 5, and the elimination body 34 removes the weight sorting body 13 every time the charging port body 5 is opened. This is to move the empty can V and the empty bottle W, which are the articles on the weight selection body 13, to a position where they can be separated. In this embodiment, it is formed on the side surface of the charging port body 5 as a projection projecting downward.

In FIGS. 1 to 4, reference numeral 35 denotes a holding body.
The presser 35 presses the empty can V or the empty bottle W, which is the article received from the input port body 5 and received by the weight separator 13, and temporarily stops the same, and the driving device 20 drives the movable pressing body 18. It is driven in conjunction with the release to release the press of the empty can V and the empty bottle W. For this reason, the pressing body 34 is rotatably supported by the side wall 52, and is operated by the driving device 20 every time the electric motor 21 makes one rotation.

1 and 3, reference numeral 36 denotes a collection box 32.
Is a sensor for detecting that the amount of empty cans V and empty bottles W accommodated in the collecting sections 32 and 33 has reached the limit.

As shown in FIGS. 1, 3 and 4, reference numeral 41 denotes a reverse switch. This reverse switch 41 is
The motor 21 of the driving device 20 is rotated in a direction opposite to the direction of rotation when the movable pressing body 28 is driven.

That is, for some reason, the input port 5
, A plurality of empty cans V may be supplied at one time, and the plurality of empty cans V may be fed between the fixed body 17 and the movable pressing body 18 of the compression unit 16 by the weight sorter 13. In addition, a plurality of crushed and deformed empty cans V are overlapped, and the weight sorter 13 is moved from the fixed body 17 to the movable pressing body 18.
May be sent between In such a case, a large resistance is applied to the movable pressing body 18 as compared with a case where one cylindrical empty can V is normally pressed and compressed. Then, the movable pressing member 18 is pushed by the cam 23 of the driving device 20 and swings in a direction approaching the fixed member 17 to try to press the empty can V. The pressing force is insufficient to press and compress the can V, and the can V stops when the compression is started.

Then, the operator operates the reverse rotation switch 41 to rotate the electric motor 21 of the driving device 20 in a direction opposite to the direction of rotation when the movable pressing body 18 is swung to the approach position 18B. Accordingly, the cam 23 also rotates in the direction opposite to the direction of rotation when the movable pressing body 18 is swung to the approach position 18B. Specifically, the motor 21 is rotated so that the cam 23 rotates in the direction of the dashed arrow. Thereby, the movable pressing body 18 moves from the position toward the approach position 18B to the separation position 1
Return to 8A. Thereafter, the reverse rotation switch 41 is intermittently operated to alternately rotate the electric motor 21 in the forward and reverse directions, thereby causing the movable pressing body 18 to reciprocate and swing, thereby compressing the empty can V. In this way, the compression operation can be continued without canning.

The reversing switch 41 is provided, for example, at an open portion facing the recovery portion 3 of the apparatus main body 1 in consideration of operational points.

As shown in FIGS. 1, 2 and 4, reference numeral 42 denotes a forcible cam, which is attached to the center of the rotating shaft 22 of the drive unit 20. For this reason, when the rotating shaft 22 rotates, it rotates together with the cam 23. 4
Reference numeral 3 denotes a cam receiving member provided on the movable pressing member 18, and the cam receiving member 43 is attached to a shaft 45 attached to an arm 44 provided at a lower portion of the movable pressing member 18 at the lower center of the driving device side surface as shown in FIG. It is rotatably supported. The cam receiving member 43 operates the movable pressing member 18 when the forcible cam 42 comes into contact therewith. That is, the operation by the combination of the forced cam 42 and the cam receiver 43 is as follows. When the movable pressing member 18 is pressed by the cam 23 and is being followed by a normal compression operation, the forcible cam 42 does not contact the cam receiving member 43 provided on the movable pressing member 18 and does not operate the movable pressing member 18.

However, when the movable pressing body 18 swings toward the fixed body 17 in the compression device 16 to compress the empty can V, the empty can V is compressed and the pull tab (opening) provided on the end face thereof is provided. The stopper (plug) may enter the gap between the side plate 17c of the fixed body 17 and the side edge of the movable pressing body 18 and may not come off. As a result, the empty can V and the movable pressing member 18 are locked, and the movable pressing member 18 cannot stop returning to the separated position due to the force of the spring 28 and is in a stopped state. Then, the driving of the compression device 16 is stopped and the compressed empty can V cannot be taken out.

As described above, when the movable pressing body 18 compresses the empty can V, a part of the compressed empty can V enters the gap between the movable pressing body 18 and other members, and the empty can V does not move. In the state where the movable pressing body 18 cannot return to the separated position 18A, when the next empty can V is inserted by opening and closing the charging opening body 5, the electric motor 21 of the driving device 20 is driven to drive the cam 23. And the forced cam 42 rotates. In other words, the forcible cam 42 forcibly presses the movable pressing body 18 to swing toward the separated position 18A against the cam receiving body 43 provided on the movable pressing body 18 while rotating in the direction of the arrow.
Therefore, the movable pressing body 18 is forcibly returned to the separated position 18A. As a result, the compressed empty can V between the movable pressing body 18 and the fixed body 17 falls and is collected in the empty can collection section 32 of the collection box 31.

In particular, this configuration is effective when the movable pressing body 18 cannot be moved by the force of the reverse rotation of the electric motor 21 of the driving device 20 and a stronger force needs to be applied to the movable pressing body 18. . Further, in the configuration using the forcible cam 42 as means for forcibly returning the movable pressing member 18 to the separated position 18A, the forcible cam 42 and the cam receiving member 43 are combined because the forcible cam 42 and the cam receiving member 43 are combined by contact. It is not necessary to provide a large strength for transmitting the rotational force of the electric motor to the movable pressing body 18, and the configuration is simple and inexpensive.

Further, when both the reverse switch 41 and the forcible cam 42 are provided, the case where the movable pressing body 18 stops at the start of the empty can compression operation by the compression device and the case where the movable pressing body stops at the time of the progress of compression respectively correspond. Then, the movable pressing body 18 can be moved to perform the compression operation.

The present invention is not limited to the above-described embodiment, but can be implemented with various modifications.

[0053]

According to the first aspect of the present invention, the movable pressing body is swung toward the position approaching the fixed body to form a V-shaped space between the movable pressing body and the fixed body. When the empty can is compressed by closing, the compressed surface portion made of an elastic material is pressed by the empty can and is immersed by elasticity, so that the empty can rises in a direction away from the swing fulcrum of the movable pressing body to hold the empty can. Therefore, it is possible to prevent the compression operation from being hindered by the lifting of the empty can, and to prevent the occurrence of a situation in which a large compression force is required when the empty can is lifted and compressed. The load on the driving device can be reduced.

According to the empty can compression apparatus of the second aspect,
When the empty can is compressed, it is possible to more reliably prevent the empty can from being lifted.
