Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can crushing device for automatically conveying and crushing empty cans such as soft drinks.

[0002]

2. Description of the Related Art Conventionally, as described in, for example, Japanese Utility Model Laid-Open No. 6-591, an empty can carrier path is installed in a machine frame and is inclined downward in a direction in which an empty can is carried by gravity. Provided in this empty can conveying path from front to rear, a swingable weight sorter, a substrate portion and a swingable crushing plate that sandwich and crush the empty can, an aluminum can and a steel using a magnet. There is known an empty can crushing device provided with a swingable separating body for separating the cans. In particular, the separating body interlocks with the crushing plate, and when the crushing plate is raised, that is, when the crushing plate is opened, it is located on the same plane as the substrate, receives the crushed empty can, and the magnet whose position is fixed is positioned downward Contact and adsorb only the steel can. Also, when the crushing plate descends, the separating body tilts to the opposite side,
The magnets separate to allow the aluminum can to fall to the side opposite the steel can.

Further, there has been proposed an empty can crushing device in which the crushing plate is electrically operated, and the crushing plate is made to interlock with the separating body as described above, and the selection body is also operated. The reason why the sorting body is interlocked is that, for example, when the crushing plate is raised, the sorting body is forcibly opened to eliminate an empty can or the like that has adhered due to the viscosity of the remaining juice liquid.

[0004] In the past, basically, an interlocking mechanism consisting of a wire was used to interlock a sorting body and a sorting body with a crushing plate.

[0005]

However, in the interlocking mechanism made of wire, the construction and adjustment are troublesome, and the operation tends to be unstable and uncertain because the wire stretches during use. In addition, since the separation body of aluminum cans and steel cans received empty cans from the substrate part in a tilted state, the adsorption force changes depending on the crushed shape of the steel can and the degree of adhesion of residual liquid, and the rotation separation At times, there was the problem that the steel can passed past the exact stop position and popped out in the rear aluminum can processing direction. Further, with respect to the aluminum can, there is a problem that the sliding force is too high and the aluminum can jumps out of a predetermined position. In order to prevent the steel can from popping out, the force of the magnet for adsorbing the steel can must be strong, and therefore an opening for exposing the magnet to the separating body is required. There has been a problem that dust is clogged to cause malfunction. Also, when the magnetic force is increased, the force to separate the empty can becomes larger than necessary,
The wire was stretched or recoiled when it was released, resulting in abnormal noise or a poor sorting rate.

The present invention is intended to solve such problems, and in the empty can crushing device, the structure of the interlocking mechanism between the pressing body such as the crushing plate and the weight sorting body is simplified, and The purpose of the present invention is to make the operation stable and reliable, and also to make the operation timing of the sorting body appropriate. In addition, the structure of the interlocking mechanism between the pressing body and the separating body is simplified, the operation is stable and reliable, and the timing of the operation of the separating body is also appropriate to ensure the separation. The purpose is to be able to.

[0007]

In order to achieve the former object, an empty can crushing device according to a first aspect of the present invention is an empty can conveying path that is inclined in a downward descending direction in a machine frame. In the empty can transport path, a sorting body that opens when a load of a predetermined amount or more is provided, and a substrate portion that is continuous below the sorting body are provided, and the pressing body and the pressing body are provided above the substrate portion. Each of the lower empty can guides is swingably opened and closed at its rear end with the left-right direction as the axis of rotation, and an interlocking mechanism consisting of a link arm that interlocks the sorting body and the empty can guide with the pressing body is provided. The interlocking mechanism rotates the empty can guide when the pressing body is moved upward and then opens the sorting body, closes the sorting body when the pressing body descends, and rotates the empty can guide downward.

In order to achieve the latter object, the empty can crushing device according to the second aspect of the present invention provides an empty can conveying path inclined in a downward descending direction in the machine frame. A substrate part and a continuous separating body are provided in the rear of the substrate part in the transport path, and a pressing body is swingably opened / closed at its rear end on the upper side of the substrate part with the left-right direction as the rotation axis direction. The separating body is supported so as to be swingable with the left-right direction as the rotation axis direction, and a magnet fixed at a position contacting and separating from the separating body is provided below the swinging body, and the separating body is attached to the pressing body. Equipped with an interlocking mechanism consisting of a link arm that interlocks
This interlocking mechanism rotates the rising-time sorting body of the pressing body in a direction tilting to one side and the descending-time sorting body of the pressing body in a direction tilting to the other side, and the rear end of the rising pushing body and the substrate portion. When a crushed empty can is passed between and, a separation body is made almost horizontal.

[0009]

In the empty can crushing device according to the first aspect of the invention, the empty can to be crushed is conveyed downward and rearward through the empty can conveying path by gravity in the machine frame. An empty can or the like placed in the machine frame is first placed on the sorting body, but when a foreign substance such as a heavy bottle is placed on the sorting body, the sorting body is opened and the foreign substance falls and is eliminated. On the other hand, when a light empty can is placed, the sorting body does not open, and the empty can moves from the sorting body to the substrate portion due to gravity. After that, the pressing body descends, and the empty can is crushed between the pressing body and the substrate portion. By the way, the interlocking mechanism including the link arm operates the sorting body and the empty can guide on the substrate unit in conjunction with the pressing body. The sorting body is forcibly opened when the pressing body is in the raised position, and eliminates empty cans and the like that have adhered to the sorting body due to the viscosity of the residual liquid of juice. On the other hand, the empty can guide on which the empty can is mounted rises as the pressing body rises and the inclination angle increases, leading the empty can to the lower side of the pressing body reliably, but lowering as the pressing body descends, Close to the department. In particular, when the pressing body is raised, the empty can guide rises before the sorting body is opened, but this ensures that the empty can that has been laid over the sorting body and the substrate section is sent to the back of the substrate section. Therefore, it is possible to prevent an erroneous operation in which the sorting body removes an empty can that can be crushed as a foreign matter.

In the empty can crushing device according to the second aspect of the invention, the empty can crushed between the pressing body and the substrate portion is sufficiently located between the rear end of the pressing body and the substrate portion when the pressing body is raised. When a large gap is formed, gravity moves through the gap and moves to the rear lower separating body, but at this time, the separating body is almost horizontal. Then, the separating body rotates in conjunction with the pressing body by the interlocking mechanism including the link arm, but when the pressing body rises, the separating body turns in the direction tilting to one side and rests on the magnet. At this time, the aluminum can slides down from the separating body to one side, but the steel can is attracted to the magnet and stops. Then,
When the pressing body descends, the separating body turns in the direction tilting to the other side and separates from the magnet. As a result, when the steel can is placed on the separating body, the adsorption to the steel can is released, and the steel can slides down from the separating body to the other. Thus, the aluminum can and the steel can are separated.

Also, the motor 71 is controlled via the motor driving means 143 according to the signal from the timer 142.

Next, the operation of the above configuration will be described. First, the usage method will be described. When the green lamp 8 is lit, empty can crushing can be performed. The user
It is only necessary to put the empty can A into the charging port 7. At this time, the axial direction of the empty can A is made to coincide with the axial direction of the charging port 7. And
By inserting the empty can A into the charging port 7, the empty can crushing device is activated to perform a certain operation, and the empty can crushing is automatically performed. If the empty can A placed in the charging port 7 advances, the next empty can A can be inserted. Thus, the green lamp 8 is always lit, but when the green lamp 8 is turned off and the white lamp 9 is lit, the containers 18 and 19 inside are full, so the door 22 is opened. Empty container A in containers 18 and 19
Dispose of. Further, the lighting of the red lamp 10 informs that the apparatus has stopped due to some abnormality. At this time, by pressing the reset button 11, the apparatus can be forcibly restarted. However, for example, if the reset button 11 is not pressed and it does not operate normally,
An inspection should be done.

Next, the operation of the empty can crushing device will be described.
As shown in FIG. 1, the state where the crushing plate 61 is at the upper limit and stopped is the standby state. The device is always stopped in this standby state. The device is activated when the sensor 58 detects that the empty can A or the like has entered the transfer body 32 from the charging port 7. Further, as will be described in detail later, in the case of an emergency stop of the device, it may be possible to restart the device by pressing the reset button 11. When the device is activated, the rod 73 is moved forward by driving the motor 71, and the crushing plate 61 is lowered. As shown in FIG. 2, the crushing plate 61 reaches the lower limit,
When this is detected by the second limit switch 82, the motor 71 reverses, the rod 73 retracts, and the crush plate 61 rises. The first limit switch 81 detects that the crushing plate 61 has reached the ascending limit, whereby the apparatus stops.

The transfer body 3 is interlocked with the operation of the crushing plate 61.
2. The sorting body 54, the empty can guide 86, and the sorting body 35 operate as follows. First of all, the transfer body 32
In the standby state, as shown in FIGS. 1 and 4, 32 is in the lower limit position by its own weight, is placed on the transfer body receiver 41, and is positioned coaxially with the opening 7 that is opened.
At this time, the push-up plate 102 is pulled downward by the wire 107 and is in the lower limit position against the spring 105. As the crushing plate 61 descends from such a standby state, the wire 107 loosens, and as shown in FIG. 2 and FIG.
The spring 105 pulls the push-up plate 102 accordingly. The push-up plate 102 pushes up the transfer body 32, and the transfer body 32 rotates. When the transfer body 32 is turned sideways to some extent, the empty can A and the like drop from the transfer body 32 onto the sorting body 54 of the weight sorter 33. When the crush plate 61 reaches the lower limit, the transfer body 32 also reaches the upper limit. After that, when the crushing plate 61 rises, the wire 107 pulls the push-up plate 102 to lower it, and accordingly, the transfer body 32 also rotates downward. As the transfer body 32 rotates upward, the lid portion 45 closes the input port 7 from the bottom, and when the transfer body 32 reaches the upper limit, the input port 7 is also completely closed. Therefore,
With the transfer body 32 not connected to the inlet 7, the inlet 7
Empty can A etc. will not be put in.

When the crushing plate 61 moves up, the drive arm 111 is initially kept at the lower limit position by gravity. During this time, the link arm 113 mounted on the roller 115 of the crushing plate 61 rotates with respect to the drive arm 111.
When the crushing plate 61 approaches the upper limit position, the bending piece 114 of the link arm 113 is caught on the crushing plate 61 from above, and thereafter,
As the crush plate 61 rises, the drive arm 111 is pulled upward via the link arm 113, and the drive arm 111 turns upward. Thus, when the drive arm 111 rotates upward, the push-up bar 116 rises and pushes up the sorting body 54, as shown in FIGS. 1 and 4. As a result, the sorting body 54 turns against the gravity and turns sideways. Further, when the crushing plate 61 descends, the opposite operation is performed, and immediately the drive arm 11
1 turns downward. Along with that, due to the gravity applied to the weight 56, the sorting body 54 rotates in the opposite direction and faces upward.

Further, as described above, when the drive arm 111 rotates upward, at least the interlocking piece 121 of the drive arm 111 is moved to the empty can guide 86.
After hitting the upper receiving piece 123 of the
Turns upwards. On the other hand, when the drive arm 111 rotates downward, the empty can guide 86 rotates downward due to gravity. At this time, the interlocking piece 121 of the drive arm 111 hits the lower receiving piece 122 of the empty can guide 86 from above, so that the empty can guide 86 surely descends.

Further, the separating body 35, in the standby state,
As shown in FIG. 1, due to gravity, the rear portion of the stopper piece 92
It is placed on the upper surface and is located on the same plane as the crushed substrate portion 34. Then, as the crush plate 61 descends, the link arm 131 descends on the front side and rises on the rear side with the spring 135 serving as a fulcrum. As a result, the sorting body 35 gradually turns in the direction in which the front side descends while the roller 134 thereof slides in the engagement groove 133 of the link arm 131. Further, when the crushing plate 61 is lowered to some extent, the link arm 131 abuts against the roller 136 of the crushing plate 61 from above. After that, the link arm 131 continues to rotate in the same direction with the roller 136 as a fulcrum, and the sorting body 35 also continues to rotate in the same direction. On the other hand, when the crushing plate 61 is lifted from the state shown in FIG.
The link arm 131 turns in the opposite direction with 136 as the fulcrum, and then the spring 135 serves as the fulcrum.
Rotate in the same opposite direction. Meanwhile, the sorting body 35 also continues to rotate in the opposite direction and returns to the standby state. It should be noted that the roller 134 is positioned in the middle of the engaging groove 133 when the separating body 35 is horizontal.

Next, the movement of one empty can A will be described.
In the machine casing 1, the empty can A is conveyed in a state in which the longitudinal direction of the machine casing 1 and the axial direction thereof coincide with each other when projected onto a horizontal plane. First, in the standby state shown in FIG. 1 and FIG.
The empty can A, which has entered the transfer body 32 from the above, slides downward and downward due to gravity, hits the end face plate 44 of the transfer body 32, and stops.
At this time, since the center angle of the transfer body 32 is as large as about 225 ° and the transfer body 32 is shaped so as to cover the empty can A from above, especially on the side opposite to the weight sorter 33, the transfer body 32 is thrown in. It is possible to prevent the empty can A from jumping out of the transfer body 32, especially on the side opposite to the weight selector 33.

Next, when the transfer body 32 turns upward around the support shaft 43 and turns sideways, as shown in FIG.
Drops from the transfer body 32 onto the sorting body 54 of the weight sorter 33. At this time, since the empty can A is only in line contact with the transfer body 32 at its protrusion 46, the empty can A is reliably transferred from the transfer body 32 onto the sorting body 54 even if there is viscosity such as juice residual liquid. Listed. If the empty can A is empty, the sorting body 54 will not rotate downward even if it is loaded.
Will slide down on the sorting body 58 rearward and downward due to gravity. At this point, as shown in FIG. 2, the crushing plate 61 is near the lower limit, and the empty can A temporarily stops by hitting the front end of the crushing plate 61.

After that, when the crushing plate 61 rises, the empty can A
Is the crushed substrate portion below the sorting body 54 due to gravity.
34 It slips up and goes under the crushing plate 61. At this time, since the empty can A is only in line contact with the sorting body 54 at its protrusion 57, the sorting body is not affected even if there is viscosity such as juice residual liquid.
It is easy to transfer from 54 to the substrate 34. And the crushing plate 61
As a result, the empty can A gradually slides backward and downward on the substrate portion 34. At this time, the axial direction of the empty can A coincides with the carrying direction. Note that as the crushing plate 61 rises, the empty can guide 86 also turns upward and its inclination angle with respect to the horizontal plane increases. As a result, the empty can A reliably slides down into the space between the substrate portion 34 and the crushing plate 61 against the viscosity of the residual juice of the juice.

Then, when the crushing plate 61 descends, the empty can A
Is crushed between the crushing plate 61 and the substrate portion 34. In addition,
When the crushing plate 61 starts to descend, the empty can guide 86 rotates downward and closes on the substrate portion 34, and the load at the time of crushing is surely received by the substrate portion 34. When this crushing is performed, the axial direction of the empty can A is in a state substantially orthogonal to the rotation axis direction of the crushing plate 61, and the empty can A is crushed from one end to the other end in order. .

At this time, first, the end portion of the empty can A is caught in one of the recesses 64 of the crushing plate 61, and the non-slip protrusions 63 of the crushing and crushing plate 61 bite into the peripheral surface of the empty can A.
As a result, the empty can A is prevented from being displaced particularly in the returning direction, and the empty can A is reliably crushed. When the empty can A shifts in the return direction and only the rear part is crushed, and the front part of the uncrushed empty can A protrudes from the substrate portion 34 to the front, the front part is caught and the empty can A is There is a risk that it will stop flowing after that, but this can be prevented. Especially, non-slip protrusions
Since the 63 are formed so as to be distributed over the entire front, rear, left, and right of the crush plate 61, the empty can A is reliably prevented from returning. For example, even if the empty can A is laterally displaced and the anti-slip projections 63 in the central portion do not bite well, the anti-slip projections 63 on the left and right sides bite into the empty can A, and the empty can A is reliably prevented from returning. .

When the crushing plate 61 reaches the lower limit, the crushing is completed, but thereafter, as the crushing plate 61 rises,
The crushed empty can A slides further rearward and downward through the gap between the rear end of the crushing plate 61 and the upper surface of the substrate portion 34, and is sent onto the substantially horizontal sorting body 35. Then the separated body
The 35 turns in the direction in which the rear side descends and rests on the magnet 93,
The aluminum can (aluminum can) A is not attracted to the magnet 93, and slides down on the separating body 35 as it is rearward and downward, falls from the rear end of the separating body 35, and the aluminum can on the rear side. It is stored in the storage container 19. On the other hand, the steel empty can (steel can) A is adsorbed by the magnet 93 and stops on the separating body 35. Then, when the crushing plate 61 descends and the sorting body 35 rotates in the direction in which the front side descends, the empty can A adsorbed by the magnet 93 and the sorting body 35 and the magnet 93 on the stopper piece 92 are attracted. After that, the suction is released and the inclined separating body 35 slides down to the front, falls from the front end of the separating body 35, and is stored in the steel can storage container 18 on the front side. In this way, aluminum cans and steel cans are automatically separated.

When a foreign substance such as a stone, a glass bottle or a can containing juice is put into the transfer body 32 through the inlet 7, if the foreign substance has a weight of a predetermined value or more, the foreign substance is After being transferred from the transfer body 32 to the weight sorter 33, it is eliminated in the weight sorter 33. That is, when the foreign matter dropped from the transfer body 32 is placed on the sorting body 54, the gravity exerted by the foreign matter exceeds the gravity exerted by the weight 56 on the sorting body 54, so that the sorting body 54 turns downward and moves sideways. open. As a result, the foreign matter falls from the sorting body 54 into the foreign matter storage container 17 and is eliminated, and is not sent to the crushed substrate portion 34. Then, the sorting body 54 rotates upward again by the load of the weight 56.

By the way, in the sorting body 54 and the empty can guide 86, after the empty can guide 86 rises, the sorting body 54
Is the timing to open sideways. This allows
The empty can A, which is laid over the sorting body 54 and the crushed substrate part 34, is surely sent to the back of the substrate part 34, and the empty can A which can be crushed is eliminated as a foreign matter by the weight sorter 33. It is possible to reduce malfunctions that would occur.

Further, in the standby state, the sorting body 54 is
The squeeze plate 61 is forcibly opened sideways in association with the crushing plate 61, whereby the empty can A or the like attached to the sorting body 54 due to the viscosity of the residual juice of the juice is forcibly dropped and eliminated.
Therefore, the operation of the device thereafter is not hindered.

As is clear from the above description of the operation of the apparatus, after a certain empty can A enters between the crushing plate 61 located at the ascending limit and the base plate portion 34, the next empty can A enters the charging port. The crushing plate 61 descends only after it is put into the transfer body 32 from 7, and the empty can A below it is crushed.

Further, when the empty can A rises up from the containers 18 and 19, the sensor 21 detects it and the green lamp 8 which is always lit up to that time is turned off, and the white lamp 9 is lit. . At the same time, the device returns to the standby state and stops, and even if the empty can A is inserted into the charging port 7 or the reset button 11 is pressed, the device does not operate unless the sensor blocker is removed.

Here, the operation of the crushing plate 61 will be supplementarily described. If it is an empty can A of a normal beverage can, the crushing plate 61
Is lowered only once, and is lowered until the second limit switch 82 is actuated, and then raised to the standby position.
On the other hand, the empty can A is considerably hard, or the empty can A is in a fixed position, that is, the substrate portion 34 and the crush plate.
When it comes to a stop at a position deep inside 61, the load of the motor 71 increases as the crushing plate 61 descends. The current of the motor 71 is detected by the overcurrent detecting means 141. If this exceeds the reference value, the second current is detected.
The crushing plate 61 rises to the standby position regardless of the limit switch 82. Further, even when a predetermined time has passed after the first limit switch 81 was activated, the crushing plate 61 is operated by the timer 142 regardless of the second limit switch 82.
Goes up to the standby position. As a result, the empty can A, which has been crushed to some extent, is sent to the back by gravity. After that, the crush plate 61 descends again to try to crush. In this way, the crushed empty can A is further sent to the fulcrum of the crushing plate 61, and then the crushing is tried again, whereby one crushing plate
You can now crush an empty can A that could not be crushed by descending 61. This attempt to lower the crush plate 61 is repeated, for example, up to three times. Meanwhile, if the second limit switch 82 is actuated, the crushing is completed, the crushing plate 61 is moved up to the standby position, and the device can continue to operate thereafter. On the other hand, 3
If the second limit switch 82 is not actuated even if the turning is attempted, the red lamp 10 lights up, the crushing plate 61 returns to the standby position, and the apparatus stops. Here, if the reset button 11 is pressed, the crushing operation is retried.

The reason why the motor 71 is controlled by the timer 142 in addition to the detection of the overcurrent of the motor 71 is as follows. That is, in the case of a foreign substance, the force to return the crushing plate 61 to the upper side may act, and there is instability in the electric circuit only by detecting the overcurrent, and the crushing plate 61 remains stopped at the intermediate position. Sometimes. In order to prevent this, a crushing plate is forcibly set by a timer when a predetermined time has passed after the last operation of the first limit switch 81.
Raise 61 to the standby position and stop. Even if the reset switches 81 and 82 are broken, the crush plate 61 can be returned to the standby position by the detection of the overcurrent or the timer 142 described above. Therefore, the motor 71 does not burn.

According to the configuration of the above-described embodiment, the transfer body 32 is provided below the charging port 7, and the weight sorter 33 is provided side by side with the transfer body 32. Rotate the transfer body 32 around a rotation axis parallel to the empty can A
Is transferred from the transfer body 32 to the weight sorter 33, the front-rear longitudinal dimension of the entire apparatus can be reduced. This allows it to be placed side by side with vending machines with small front and rear dimensions without problems.

Even if a hand, an umbrella, or the like is put in the input port 7 by mischief or the like by bending the empty can carrying path 31 from the input port 7 to the weight selector 33 by the transfer body 32,
These hands and umbrellas do not reach the crushing plate 61 and are safe.

Further, since the drive arm 111 and the link arms 113 and 131 are used for interlocking the sorting body 54, the empty can guide 86 and the separating body 35 with the crushing plate 61, compared with the case where a wire is used. , While reducing the number of parts,
The operation can be made reliable and stable.

In particular, with respect to the sorting body 54 and the empty can guide 86, the timing for opening the sorting body 54 sideways after raising the empty can guide 86 is used. However, by interlocking with the drive arm 111 and the link arm 113, In manufacturing the device, it becomes easy to take the above timing.

Further, since the crushing plate 61 and the separating body 35 are interlocked by using the link arm 131, the separating body 35 can be slowly operated at a constant speed. As a result, as described above, the separating body 35 is not tilted and positioned on the same plane as the crushing substrate portion 34 but is in a substantially horizontal state, and an empty can is placed on the separating body 35 from the crushing substrate portion 34. It is possible for A to transfer. Therefore, the aluminum can is prevented from popping out behind the aluminum can storage container 19 due to excessive force. In addition, the steel cans are not adsorbed excessively and are not stored in the steel can storage container 18, and the sorting can be ensured. Along with this, the force of the magnet 93 for adsorbing the steel can may be weak. As a result, the opening that exposes the magnet 93 is separated into a separate body.
It is not necessary to form it in 35, and it is possible to prevent malfunction due to clogging of dust in the opening. Also, the separation body 35
The operation of is slow, and the force for separating the steel can is small, so that the generation of abnormal noise can be reduced.

Further, as described above, by increasing the anti-slip protrusions 63 of the crushing plate 61, it is possible to reliably prevent the empty can A from shifting in the returning direction due to the crushing. The front ends of the plate 61 and the crushed substrate portion 34 are located at substantially the same position. This allows the weight sorter 33
A foreign substance such as a bottle transferred to is placed on the front part of the substrate part 34. It is possible to prevent the weight sorting from being not properly performed.

Further, when the overcurrent of the motor 71 is detected and the crushing plate 61 cannot be crushed by one downward movement, for example, the crushing of the empty can A is repeated up to three times. Even a hard empty can A can be crushed securely while preventing an excessive load. Moreover, the timer further improves the reliability.

FIG. 8 shows another embodiment of the present invention.
In this embodiment, the optical sensor 58a for the transfer body 32,
Two pairs of 58b are provided in front and back. The distance between the two sensors 58a and 58b along the empty can conveying path is larger than the axial length of the empty can A of the 500 ml can. Therefore, when the empty can A is correctly inserted, the sensor 58a on the front side is
Is detected and turned on, then turned off, and then the sensor on the rear side
58b detects empty can A and turns it on. In this case, the motor
71 starts up. On the other hand, when a foreign material such as a hand or a weekly magazine is mistakenly inserted into the inlet 7, the front sensor 58a is turned on, and the rear sensor 58b is also turned on. In this case, the motor 71 does not start and the buzzer sounds to warn the user. When the foreign matter is pulled out, it returns to the initial state. Further, in the former case, and when a foreign object is immediately put in the insertion port 7, the sensor 58a on the front side is also turned on, but the motor 71 continues to operate. But,
When returning to the initial state again, both the sensors 58a and 58b are in the ON state, so that the device is stopped and the buzzer sounds. Even in this case, since the transfer body 32 is operated by the force of the spring 105, it does not crush the empty can A or the hand.

The present invention is not limited to the above embodiment, and various modifications can be made. For example,
In the above-described embodiment, the foreign matter storage container 17 is provided on the upper side of the cross rail 16, and the steel can storage container 18 and the aluminum can storage container 19 are provided side by side on the lower side. On the lower side, a foreign substance storage container, a steel can storage container, and an aluminum can storage container may be provided side by side in this order from front to back. Further, in the above-mentioned embodiment, the transfer body 32 is arranged on the left side and the weight sorter 33 is arranged on the right side.

According to the invention of claim 1, since the interlocking mechanism for interlocking the selecting body and the empty can guide with the pressing body is composed of the link arm, the structure of the interlocking mechanism can be simplified. The operation can be made reliable and stable, and the timing of the operation of the sorting body and the empty can guide can be easily adjusted in manufacturing. Then, after the empty can guide for surely feeding the empty cans on the board part is raised, the sorting body is opened sideways to remove the empty cans that could not be fed. Therefore, the empty can that seems to be laid over the substrate part is reliably sent to the back of the substrate part, and it is possible to reduce malfunctions such that the empty can that can be crushed is removed as a foreign substance by the weight sorter. .

According to the invention of claim 2, since the interlocking mechanism for interlocking the separating body with the pressing body is composed of the link arm, the structure of the interlocking mechanism can be simplified and its operation is reliable and stable. In addition, the separation body can be operated slowly at a constant speed. Then, with the sorting body almost horizontal, an empty can can be transferred from the substrate part onto the sorting body, so that it is possible that the aluminum can or the steel can jumps out of the predetermined position due to excessive force. It is possible to prevent it, to ensure the separation, and to weaken the force of the magnet for adsorbing the steel can. Therefore, it is not necessary to form an opening for exposing the magnet in a separate body, and it is possible to prevent malfunction due to clogging of the opening with dust. Together with this, the operation of the separating body can be slowed down, so that the force for separating the empty can can be reduced and the generation of abnormal noise can be prevented.
