DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste container sorting apparatus for sorting empty waste containers such as steel cans, plastic cans, aluminum cans, and glass bottles containing soft drinks or alcoholic beverages. Along with separating relatively heavy waste containers such as glass bottles and cans containing leftovers,
The present invention relates to a separation device for waste containers that separates magnetically adherent containers such as steel cans from non-magnetically adherent containers such as aluminum cans.

[0002]

2. Description of the Related Art Conventionally, as this type of waste container sorting apparatus, for example, one disclosed in Japanese Patent Application Laid-Open No. 6-156609 is known. This waste container sorting apparatus is shown in FIG.
As shown in FIG. 1, an input port 2 provided in the machine frame 1 and into which the waste container H is inserted with its axis substantially constant, and a receiving portion for temporarily receiving and releasing the waste container H input into the input port 2. Mechanism 3
And receiving the waste container H released from the receiving mechanism 3 and dividing the waste container H into a waste container H having a predetermined weight or more and a waste container H having a predetermined weight or less.
And a waste container H having a predetermined weight or less separated by the primary separation mechanism into a magnetically-attached container and a non-magnetically-attached container. And a secondary sorting mechanism 5 for guiding to the container storage area LA.

[0003] The receiving mechanism 3 has a plurality of blades 6 which extend radially and receive the waste container H put into the inlet 2.
An impeller 7 is rotatably supported by the machine frame 1 and releases the waste container H temporarily received by the blade 6 by this rotation to drop. The primary sorting mechanism 4 has two positions, an upper support position X for supporting the waste container H released from the receiving portion mechanism 3 and falling and rolling forward, and a drop position Y for dropping the waste container H to the rear. A support member 8 rotatably supported by the machine frame 1 so as to be movable to a predetermined position, and a waste container H provided at a front side of the support member 8 and positioned at the support position X and supported by a predetermined position. When the weight is greater than the bearing member 8
Is rotated to the drop position Y to drop the waste container H to the heavy container storage area GA. The secondary sorting mechanism 5 includes a rolling plate 10 for rolling the waste container H rolling the support member 8 of the primary sorting mechanism 4, and a non-magnetic material such as an aluminum can provided on the upstream side of the rolling plate 10. Hole 11 for dropping an adhesive container into non-magnetically-attached container housing area LA
And a magnet 12 provided above the first hole 11 for pulling a magnetically adhering container such as a steel can and passing the position of the first hole 11 to roll downstream, and a magnet 12 downstream of the rolling plate 10. A second hole 13 for dropping a magnetically-adhesive container such as a steel can into the magnetic-adhesive container housing area SA.

[0004] When the waste container H is supplied from the input port 2, the waste container H is transferred to the blade 6 of the impeller 7 of the receiving mechanism 3.
Is temporarily released by the rotation of the impeller 7, falls, and is supported by the support member 8 of the primary sorting mechanism 5. In this case, if the waste container H is a relatively heavy waste container H such as a glass bottle or a can containing leftovers, and if the waste container H is a predetermined weight or more, the support member 8 rotates rearward. H is dropped into the heavy container housing area GA. When the weight is equal to or less than the predetermined weight, the support member 8 does not rotate but guides the waste container H to the downstream side, and rolls on the rolling plate 10 of the secondary sorting mechanism 5. In this case, if the waste container H is a nonmagnetic container such as an aluminum can, the waste container H falls from the first hole 11 of the rolling plate 10 to the nonmagnetic container housing area LA. If the waste container H is a magnetically adhered container such as a steel can, the waste container H is pulled by the magnet 12, passed through the position of the first hole 11, and rolled downstream. When the waste container H reaches the second hole 13 of the rolling plate 10, the waste container H falls into the magnetically-adhesive container storage area SA. Sorting is performed in this manner.

[0005]

In this conventional waste container separation apparatus, the waste container H is provided with a receiving mechanism 3.
Is temporarily received by the impeller 7, but is released by the rotation of the impeller 7 and falls, so that when it gains momentum, the weight is not detected by the support member 8 of the primary sorting mechanism 4, and the primary separation mechanism 4 jumps out downstream. It may fall from the first hole 11 downstream to the non-magnetic container housing area LA, or may drop from the second hole 13 to the magnetic container housing area SA. There was a problem. In particular, since the impeller 7 is more likely to rotate as the waste container H to be loaded is heavier, the separation accuracy in the primary separation mechanism 4 is deteriorated. Further, when the impeller 7 is released by the rotation of the impeller 7 and falls and collides with the support member 8, the posture is changed. For example, the axis of the waste container H is displaced by about 90 degrees (FIG. 7Ha), and the rolling can be performed. There is also a problem that container clogging may occur due to disappearance, and operation efficiency may be deteriorated due to maintenance or the like.

In addition, there is a distance between the inlet 2 and the blade 6 of the impeller 7, and the waste container H that is thrown into the blade 6 has a momentum. Tends to occur. Furthermore, since the magnet 12 for separating the magnetically adhered container is provided above, the influence of the magnetic force differs depending on the shape and size of the waste container H, and separation errors easily occur. For example, if the steel can is thin, there is a high probability that the steel can falls from the first hole 11 to the non-magnetizing storage area SA without being affected by magnetic force, and if the can is thick, it is magnetically attached to the magnet 12 and sticks. And the probability of container clogging increases.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and enables a waste container to be rolled as slowly as possible so as not to fly out due to momentum and to prevent a change in posture. In addition, it is an object of the present invention to provide a waste container sorting apparatus that improves sorting accuracy, prevents clogging of containers, and improves operating efficiency.

A waste container separation apparatus comprising: a waste container divided into a magnetically magnetized container and a non-magnetically magnetized container; and a secondary separation mechanism for guiding the waste container to the magnetically magnetized container-containing area and the non-magnetically magnetized container-containing area, respectively. The receiving mechanism has a receiving surface for receiving the waste container, and has a receiving surface. A receiving plate rotatably supported by the machine frame so as to be movable to two positions, an upper receiving position for receiving the waste container and a lower releasing position for rolling and releasing the waste container forward. When the waste container is received, the receiving plate is urged toward the receiving position provided on the rear side of the receiving plate, and when the waste container is received, the receiving plate rotates by its own weight toward the release position side. An allowable weight and a stopper for stopping the receiving plate, which is rotated upward by the urging force of the weight, at the receiving position, are provided. As a result, a load is applied to the receiving plate of the receiving portion mechanism on the opposite side with a weight so that the receiving plate does not suddenly rotate, and the waste container is stopped on the receiving plate for a short time, so that the waste container vigorously Since there is no pop-out and the posture is hard to change, mistakes in separation at the downstream are reduced, and the separation accuracy is improved.

[0009] If necessary, the primary sorting mechanism may be brought into contact with the receiving plate when the receiving plate of the receiving portion mechanism is moved to the release position, and the receiving surface may continue to roll from the receiving surface.

It comprises. With this, when the receiving plate is moved to the release position, the receiving surface of the receiving plate and the supporting surface of the supporting plate are connected and the waste container is transferred, so that there is no step, so the impact of transferring is relieved, The transfer of the waste container is performed smoothly, so that the waste container does not pop out vigorously and the posture is adjusted, so that the waste container is prevented from being caught and clogged, and mistakes in separation at the downstream are prevented. It is reduced and the sorting accuracy is improved.

[0010] If necessary, the secondary sorting mechanism may be connected to the waste container which is continuous with the bearing surface of the bearing plate at the bearing position of the primary sorting mechanism and rolls on the bearing surface of the bearing plate.

If necessary, the inlet is formed in such a size that the waste container can be inserted and inserted in the axial direction thereof, and the receiving position of the receiving plate of the receiving mechanism is adjusted to the position of the waste container. The waste container is set at a position where the waste container can come into contact with the receiving surface during insertion into the insertion port. As a result, since the waste container is brought into contact with the receiving surface during insertion and received, the waste container does not collide with the receiving plate by being thrown, and since there is almost no impact, the waste container does not pop out vigorously, In addition, since the posture is also adjusted, the situation where the waste container is caught and clogged is prevented, the mistake in sorting downstream is reduced, and the sorting accuracy is improved.

Since the posture of the waste container is adjusted by the regulating plate, a situation in which the waste container is caught and clogged is prevented, mistakes in sorting on the front side are reduced, and sorting accuracy is improved. In this configuration, when the waste container inserted from the inlet is a magnetically-adhesive container, the regulating plate may be provided with a magnet that regulates the waste container so that its axis is oriented in a substantially constant direction. It is valid. Since the magnet provided on the regulating plate acts to draw the waste container toward the regulating plate to some extent, this also regulates the waste container so that its axis is oriented in a substantially constant direction, and adjusts the posture of the waste container. Furthermore, if necessary, a weight adjusting section for adjusting the predetermined weight is provided for changing the position of the weight and separating the waste container into a waste container having a predetermined weight or more and a waste container having a predetermined weight or less. Further, if necessary, a rotation speed adjusting unit for changing the position of the weight and changing the rotation speed of the receiving plate due to its own weight of the waste container is provided.

Further, if necessary, a weight adjusting portion for adjusting the predetermined weight for changing the position of the weight to separate the waste container having the predetermined weight or more from the waste container having the predetermined weight or less is provided. . Thereby, the magnetically-attached container that contains the liquid left undrinked and is heavy is separated from the non-magnetically-attached container such as a glass bottle, and the separation accuracy is improved. Further, in this configuration, if necessary, the separate sorting mechanism may include a rolling surface for rolling the waste container having a predetermined weight or more separated by the primary sorting mechanism, and the waste container may be continuously connected to the rolling surface. A guide plate having a curved surface that can be released in a tangential direction along the rolling surface, an extended surface that is continuous with the curved surface and extends forward, and a magnet provided on the guide plate and reaching the curved surface. And a separate magnet that guides the adhesive container to the magnetic container housing area of the magnetic container separated by the secondary sorting mechanism along the extension surface.

Therefore, the rolling speed of the waste container H can be adjusted, and optimal conditions can be achieved. Further, in the receiving mechanism 30, a stopper 40 stops the receiving plate 31, which is rotated upward by the urging force of the weight 35, at the receiving position A, and is constituted by a lower edge of a regulating plate 42 described later. Reference numeral 41 denotes a limit stopper that determines a moving end of the receiving plate 31 to the release position B side. The limiting stopper 41 is formed of a pin that abuts a rear end of the receiving plate 31 and is provided on the machine frame 20. In addition, before and after the receiving surface 32 at the receiving position A of the receiving plate 31 of the receiving portion mechanism 30, the waste container H supplied from the input port 21 is regulated so that its axis is oriented in a substantially constant direction,

There is provided a magnet 44 for regulating the magnetically-adhered container inserted from above so that its axis is oriented in a substantially constant direction.

The primary sorting mechanism 50 has a support plate 51 for supporting the waste container H transferred from the receiving mechanism 30. When the receiving plate 31 of the receiving mechanism 30 is moved to the release position B, the supporting plate 51 is brought into contact with the receiving plate 31 so that the receiving surface 32 is continuous and the waste container is rolled and released from the receiving surface 32. Bearing surface 5 that supports H and rolls forward
Two. The support plate 51 has a support position X inclined downward to the downstream side supporting the waste container H on the support surface 52 and a falling position Y inclined reversely to drop the waste container H rearward at the intermediate portion thereof. Are rotatably supported by the machine frame 20 via bearings 53 so as to be movable to two positions. The rotating shaft 54 is connected to the receiving mechanism 30.

A weight 55 is provided to allow the first to rotate to the drop position Y side. In the primary sorting mechanism 50, 56
Is a stopper for stopping the support plate 51 rotated upward by the urging force of the weight 55 at the support position X. As shown in FIG. 6, the stopper 56 is formed by an upper end portion of a curved surface 62 of a discharge plate 61 described later. In addition, a concave portion 58 that allows the weight 55 to pass when the support plate 51 rotates is provided at the upper end of the discharge plate 61 so as not to interfere. As shown in FIG. 6, reference numeral 57 denotes a waste container H having a weight equal to or greater than a predetermined weight and a waste container H having a weight equal to or less than a predetermined weight.
And a weight adjustment unit that adjusts the predetermined weight to separate the weight. The weight adjusting portion 57 includes a hanging piece 57a for hanging the weight 55, and a long hole 57 provided in the hanging piece 57a.
and a screw 57c that is inserted into the elongated hole 57b and relatively moves in the elongated hole 57b and is screwed into the front side of the support plate 51 to fix the hanging piece 57a.
By changing the fixed position with respect to 7c, the weight 5
The biasing force can be adjusted by changing the position of the so-called force point with respect to the bearing surface 52 of No. 5. Thereby, the predetermined weight can be adjusted, so that it is easy to set the optimum sorting conditions.

The secondary sorting mechanism 60 is fixed to the machine frame 20, receives the waste container H having a weight equal to or less than a predetermined weight separated by the primary sorting mechanism 50, and discharges the waste container H into a magnetically magnetized container and a non-magnetically magnetized container. The discharge plate 61 is provided. The discharge plate 61 substantially follows the supporting surface 52 of the waste container H that is continuous with the supporting surface 52 of the supporting plate 51 at the supporting position X of the primary sorting mechanism 50 and rolls on the supporting surface 52 of the supporting plate 51. It has a curved surface 62 that is tangential and can be released toward the non-magnetically magnetized container housing area LA, and an extended surface 63 that is continuous with the curved surface 62 and extends rearward. At an appropriate position on the back side of the discharge plate 61, a magnet 64 is provided which draws the magnetically-adhesive container that has reached the curved surface 62 and drops the magnetic-adhesive container along the extension surface 63 onto the magnetically-adhesive container housing area SA.

The separate sorting mechanism 70 includes a rolling surface 72 for rolling the waste container H having a predetermined weight or more separated by the primary sorting mechanism 50, and the rolling surface 72 which is continuous with the rolling surface 72 and rolls the waste container H. Face 72
And a guide plate 71 having a curved surface 73 that can be released in a tangential direction along the curved surface 73 and an extension surface 74 that is continuous with the curved surface 73 and extends forward. The rolling surface 72 of the guide plate 71 supports the support plate 51 that has been turned to the drop position Y.
And is located at a position continuous with the bearing surface 52 in contact with the rear end. The guide plate 71 draws the magnetically-adhesive container that has reached the curved surface 73, and draws the magnetic-adhesive container storage area SA of the magnetic-adhesive container separated by the secondary sorting mechanism 60 along the extension surface 74. Is provided. The release plate 61 and the guide plate 71 are formed of a non-magnetically adherent metal plate so that the drawn-in magnetically adhered container can be easily separated from the magnet 64 and the separate magnet 75.

Therefore, according to the waste container sorting apparatus according to the embodiment of the present invention, the waste container H is treated as follows. First, as shown in FIG. 1 and FIG.
Is input from the input port 21. In this case, since the introduction port 21 is provided with the cylindrical guide 22, the waste container H is surely introduced with the axis line substantially in a fixed direction, and the posture is maintained in a normal position. The receiving plate 31 of the receiving mechanism 30
Is set at a position where the waste container H can come into contact with the receiving surface 32 during the insertion of the waste container H into the insertion port 21, so that the waste container H comes into contact with the receiving surface 32 during the insertion. The waste container H does not strongly collide with the receiving plate 31 by being thrown, and there is almost no impact. Therefore, the waste container H does not pop out vigorously and the posture is adjusted. When the water flows to the front side, it is possible to prevent a situation where the user accidentally jumps into another area, to reduce a sorting error, and to prevent the waste container H from being caught and clogged.

As shown in FIG. 2, the waste container H supplied from the input port 21 is received on the receiving surface 32 of the receiving plate 31 of the receiving mechanism 30. In this case, the waste container H is sandwiched between the front and rear regulating plates 42 and 43 and is regulated such that its axis is directed in a substantially constant direction. Therefore, the posture of the waste container H is adjusted, and therefore, the waste container H flows forward. In this case, the situation in which the waste container H is caught and clogged is prevented, and sorting errors at the front side are reduced. When the waste container H is a magnetically-adhered container, the magnet 44 provided on the regulating plate 43 acts,
Since the waste container H is drawn to the restricting plate 43 to some extent, the waste container H is also regulated so that its axis is oriented in a substantially constant direction. At this point, the posture of the waste container H is adjusted, and therefore, the waste container H flows forward. When going, the situation where the waste container H is caught and clogged is prevented. Then, as shown in FIG. 3, the receiving portion mechanism 30 receiving the waste container H on the receiving surface 32
The receiving plate 31 rotates toward the release position B side against the urging force of the weight 35 by the weight of the waste container H. in this case,
Since a load is applied to the receiving plate 31 of the receiving unit mechanism 30 on the opposite side by the weight 35, the receiving plate 31 does not suddenly rotate, and the waste container H moves downstream while being stopped on the receiving plate 31. Moved. Therefore, the waste container H does not pop out vigorously and the posture is hard to change, so that when flowing forward, it is prevented that the waste container H jumps into another area by mistake, and sorting errors are reduced. This prevents the waste container H from being caught and clogged.

As shown in FIG. 3, when the receiving plate 31 rotates to the release position B, the receiving plate 31 comes into contact with the supporting plate 51 of the primary sorting mechanism 50, and the receiving surface 32 and the supporting surface 52 are continuously connected. Therefore, the waste container H rolls and is transferred to the bearing surface 52. In this case, the waste container H in which the receiving surface 32 of the receiving plate 31 and the supporting surface 52 of the supporting plate 51 roll continuously.
Since the delivery, there is no step, the impact of the delivery is relieved, and the delivery of the waste container H is performed smoothly, so that the waste container H does not pop out vigorously and the posture is hard to change. Therefore, when flowing to the front side, it is possible to prevent a situation where the user accidentally jumps into another area, reduce sorting errors, and prevent a situation where the waste container H is caught and clogged. Then, as shown in FIG. 4, when the receiving plate 31 is rotated to the release position B and the load of the waste container H is applied to the support plate 51, the waste container H is made of a relatively small material such as a glass bottle or a can containing leftovers. In the case of a heavy waste container H, if this is a predetermined weight or more, the support plate 51 is placed in the falling position Y against the urging force of the weight 55.
And the waste container H is dropped to the rear side.

As shown in FIG. 4, at the falling position Y of the bearing plate 51, the bearing plate 51 comes into contact with the rolling surface 72 of the guide plate 71 of the separate sorting mechanism 70, and the bearing surface 52 and the rolling surface 72. And the rolling waste container H is delivered to the rolling surface 72. This waste container H has a rolling surface 72.
When the waste container H is a non-magnetizable container such as a glass bottle, it is discharged in a tangential direction along the rolling surface 72 and falls into the heavy container housing area GA when the waste container H is a non-magnetic container such as a glass bottle. I will do it. On the other hand, in the case where the waste container H reaching the curved surface 73 is a magnetically adherent container such as a steel can or the like that contains the liquid left over and is heavy, the waste container H is separated by the separate magnet 75. Is drawn along the extension surface 74,
It falls into the magnetically-adhesive container storage area SA. in this case,
Since the magnetically-adhesive container that contains the liquid left behind and is heavy is separated from the non-magnetically-adhesive container such as a glass bottle, the separation accuracy is improved. It should be noted that the heavy aluminum can that contains the liquid left behind is dropped into the heavy container housing area GA and mixed with the glass bottle, but may be manually separated later. In this case, since at least the magnetically-adhesive container is removed, the separation is extremely easy, and the separation efficiency is improved. In the separation of the separate sorting mechanism 70, the bearing surface 52 of the support plate 51 and the rolling surface 72 of the guide plate 71 are transferred continuously, and the waste container H is transferred. The container H is softened, and the delivery of the waste container H is performed smoothly. Therefore, the waste container H does not pop out vigorously.
Since the posture does not easily change, a situation where the user accidentally jumps into another area is prevented, a sorting error is reduced, and a situation where the waste container H is caught and clogged is prevented.

Next, as shown in FIG.
Returning to 0, when the receiving plate 31 of the receiving mechanism 30 rotates to the release position B and the load of the waste container H acts on the support plate 51, the waste container H is relatively light, such as an empty aluminum can or steel can. In the case of the waste container H, when the weight is equal to or less than the predetermined weight, the support plate 51 does not rotate, so the waste container H rolls on the support surface 52 and is guided to the secondary sorting mechanism 60. The bearing surface 52 of the bearing plate 51 is attached to the secondary sorting mechanism 6.
Since the waste container H is continuous with the curved surface 62 of the zero discharge plate 61, the waste container H rolls on the curved surface 62. When reaching the curved surface 62, when the waste container H is a non-magnetically adhered container such as an aluminum can, the waste container H is discharged in a tangential direction substantially along the rolling surface 72, and falls into the non-magnetically adhered container housing area LA. To go. On the other hand, when the waste container H reaching the curved surface 62 is a magnetically-adhesive container such as a steel can, the waste container H is drawn in along the extension surface 63 by the magnet 64, and the magnetic-adhesive container storage area is drawn. Falling to SA. In this case, since the extension surface 63 extends rearward, the retracted waste container H is easily dropped and separated easily. Further, since the magnet 64 is provided on the discharge plate 61 and exerts a magnetic force from below unlike the conventional case, the magnet 64 can be pulled in regardless of the thickness of the container, and the magnetically-adhesive container can be reliably separated. Further, in the separation by the secondary separation mechanism 60, the waste container H does not pop out vigorously and the posture is hard to change, so that a situation in which the waste container H jumps into another area by mistake is prevented, and separation errors are reduced. As a result, the sorting accuracy is improved, and the waste container H is prevented from being caught and clogged. Further, since the magnetically-adhered container is stored in the same magnetic-adhesive-container storage area SA as the waste container H having the predetermined weight or more and the waste container H having the predetermined weight or less, the separation efficiency is improved.

As described above, according to the waste container sorting apparatus of the present invention, the receiving portion mechanism is provided with a receiving plate rotatable between two positions, a receiving position and a releasing position for receiving the waste container, and the receiving plate. Since the weight is applied to the receiving plate by the weight and the weight of the waste container is allowed to rotate to the release position by the weight of the waste container. As a result, the receiving plate does not rotate suddenly, and the waste container can be gently rolled downstream while being stopped on the receiving plate. Therefore, the waste container does not pop out vigorously, and the posture is hard to change, so that when flowing to the front side, it is possible to prevent the situation that it accidentally jumps into another area, and it is possible to reduce sorting errors. Therefore, the separation accuracy can be improved, and the waste container is less likely to be caught and clogged, so that maintenance is reduced and the operation efficiency can be improved.

When the receiving plate of the receiving mechanism is moved to the release position, the primary sorting mechanism has a supporting surface that abuts the receiving plate, makes the receiving surface continuous, supports the waste container, and rolls forward. When the supporting plate includes a rotatable support plate and a weight that allows the support plate to rotate to the drop position side when the waste container supported on the support surface has a predetermined weight or more, the receiving plate is released. When the waste container is transferred, the receiving surface of the receiving plate and the supporting surface of the supporting plate
Because there are no steps, the impact of delivery is reduced,
The transfer of waste containers is carried out smoothly, so that the waste containers do not pop out vigorously and the posture is hard to change, so that when flowing to the front side, it is possible to prevent accidental jumping into another area Since the sorting error can be reduced, the sorting accuracy can be further improved, and the waste container is less likely to be caught and clogged, and the operating efficiency can be further improved accordingly.

Further, the secondary sorting mechanism is connected to the curved surface which is continuous with the bearing surface of the bearing plate at the bearing position of the primary sorting mechanism and which can discharge the waste container in a tangential direction substantially along the bearing surface direction. In the case of comprising a discharge plate having an extension surface that is continuous and extending to the rear side, and a magnet that is provided on the discharge plate and that pulls in the magnetically adhered container that has reached the curved surface and drops along the extension surface. Since the extension surface extends rearward, the retracted waste container easily falls and can be easily separated. In addition, since the magnet is provided on the discharge plate and exerts a magnetic force from below unlike the related art, it can be pulled in regardless of the thickness of the container, and the magnetically adhered container can be reliably separated. Separation accuracy can be improved.

Further, the inlet is formed in such a size that the waste container can be inserted into the waste container by inserting it in the axial direction, and the receiving position of the receiving plate of the receiving mechanism is adjusted during the insertion of the waste container into the inlet. When the waste container is set at a position where it can be brought into contact with the receiving surface, the waste container is brought into contact with the receiving surface during insertion, and the container is received. Because there is no waste container, the waste container does not pop out vigorously and the posture is hard to change, so when flowing to the front side, it is possible to prevent the situation that it accidentally jumps into another area, and mistakes in sorting Since it can be reduced, the accuracy of sorting can be improved, and the waste container is less likely to be caught and clogged, so that the operation efficiency can be improved accordingly.

Further, in the case where a pair of regulating plates are provided before and after the receiving position of the receiving plate of the receiving mechanism so as to regulate the axis of the waste container to be inserted from the charging port so that its axis is directed in a substantially constant direction. Since the posture of the waste container can be adjusted by the regulating plate, it is possible to prevent the waste container from being caught and clogged, to reduce a separation error on the front side, and to improve the separation accuracy. In this case, the regulation plate
When the waste container introduced from the inlet is a magnetically adhered container, if the waste container is provided with a magnet for regulating the axis of the waste container so as to be directed in a substantially constant direction, the introduced magnetically adhered container can be used. Since the magnet provided on the regulating plate acts and is drawn to the regulating plate side to some extent, the waste container can also be regulated so that its axis is oriented in a substantially constant direction.
The posture of the waste container can be adjusted, and the situation in which the waste container is caught and clogged when flowing to the front side can be prevented.

Further, in the case where a weight adjusting portion for adjusting the predetermined weight for changing the position of the weight and separating the waste container into a waste container having a predetermined weight or more and a waste container having a predetermined weight or less is provided. Since the biasing force can be adjusted by changing the position of the so-called power point with respect to the surface, it is possible to easily set the optimum sorting conditions. Also,
In the case where a rotation speed adjusting unit that changes the position of the weight and changes the rotation speed of the receiving plate due to the weight of the waste container is provided, the position of the so-called force point with respect to the receiving surface of the weight is changed to adjust the biasing force. Therefore, the rolling speed of the waste container can be adjusted, and the optimum conditions can be easily set.

Further, when a separate sorting mechanism is provided for separating the magnetically-adhesive container from among the waste containers having a predetermined weight or more separated by the primary sorting mechanism, the liquid left behind is contained and is heavy. Since such a magnetically adhered container is separated from a non-magnetically adhered container such as a glass bottle, the accuracy of separation can be improved accordingly. Further, the separate sorting mechanism is provided on a guide plate having a curved surface capable of discharging the waste container in a tangential direction along the rolling surface, and a guide plate having an extension surface continuous with the curved surface and extending forward. A separate magnet that draws in the magnetically-adhered container that has reached the curved surface and guides the magnetic-adhesive container to the magnetic-adhesive container housing area of the magnetically-adhered container separated by the secondary separation mechanism along the extension surface. In this case, in the magnetically adhered container, both the waste container having the predetermined weight or more and the waste container having the predetermined weight or less can be stored in the same magnetically magnetic container storage area. Can be improved.
