Description

  The present invention relates to a sorting apparatus that can separate used PET bottles from empty cans (aluminum cans, steel cans) with a simple mechanism that does not use sensors or power.

PET bottles, steel cans, aluminum cans, and the like are used as beverage containers. In order to recycle these containers, it is first necessary to separate them.
A plastic bottle sorter for separating used plastic bottles, bottles, iron cans and aluminum cans is described in Japanese Patent Application Laid-Open No. 2000-254591 (Patent Document 1).

Japanese Patent Laid-Open No. 2000-254591

In the plastic bottle sorter described in Patent Document 1, paying attention to the fact that the length of the plastic bottle is longer than the length of the bottle or can, the plastic bottle is separated from the bottle or can. That is, the plastic bottle is sorted by the sorting bar provided immediately below the container inlet.
In recent years, however, beverage cans of various lengths have been provided, and some of them can be as long as a plastic bottle.

  An object of the present invention is to provide an apparatus that can separate empty PET bottles from empty cans (aluminum cans and steel cans) at low cost, in other words, an apparatus that can separate them with a simple mechanism that does not use sensors or power. It is another object of the present invention to enable separation even when the empty can is the same length as the empty PET bottle.

A PET bottle sorting apparatus characterized by that.

According to the first configuration, the receiving unit 1 that drops the plastic bottle 6 that has been put in the sideways direction, and the mouth region 63 of the PET bottle 6 that falls from the receiving unit 1 below the receiving unit 1 should be in contact with each other. Temporary hooking means 2 provided with a stopper 20 and a plate-like part 35 (36) provided below the temporary hooking means 2 for dividing the destination of the fallen object 6/7 at the upper edge 30 The temporary latching means 2 has a plastic bottle 6 that is latched by the latching part 20 and separated from the plastic bottle 6, and a bottom part 65 of the upper part 30 of the plate-like part 35 (36). The upper edge 30 of the plate-like portion 35 (36) of the sorting means 3 is provided at a height that does not interfere with the bottom portion 65 of the plastic bottle 6 rotated by the temporary hooking means 2. Since this is a PET bottle sorting device characterized by The Tobotoru 6, can be fed to the side beyond the upper edge 30 of the plate-like portion 35 of the dividing means 3 (36). In addition, the driving force, the driving force transmission mechanism, or a simple mechanism that does not use a sensor or the like is low in cost.

Since it has as a plate-shaped part, the extracted PET bottle 6 can be sent into the PET bottle accommodating part 96 with a simple mechanism.
In the configuration 3, in the configuration 2, the fallen object 7 that has not reached the ramp 35 is sent to the second accommodating portion 97 below the position where the upper edge 30 of the upper slope 351 of the ramp 35 is removed. Since the second ramp 4 is provided, falling objects that have not been sent to the plastic bottle storage portion 96 can be sent to the second storage portion 97.
In the configuration 4, in the configuration 1, the sorting means 3 has a partition wall 36 for forming a region beyond the upper edge 30 as a plastic bottle storage chamber 96A as the plate-like portion. The bottle 6 can be stored in the PET bottle storage chamber 96A with a simple mechanism.
In the configuration 5, in any one of the configurations 1 to 4, the receiving unit 1 drops the loaded can 7 sideways, and the upper edge 30 of the sorting means 3 falls from the receiving unit 1. Since the plastic bottle 6 detached from the temporary latching means 2 is located between the position just below the center of gravity 7c and the position just below the latching portion 20 of the temporary latching means 2, the side opposite the upper edge 30 of the sorting means 3 ( The can 7 can be fed more reliably to the side beyond the upper edge 30 and the can 7 detached from the temporary latching means 2 can be more reliably dropped to the side not exceeding the upper edge 30 of the sorting means 3. Can do.
Configuration 6 is that in Configuration 5, the upper edge 30 of the sorting means 3 is directly below the position of the center of gravity 7c of the can 7 falling from the receiving portion 1 and directly below the position of the center of gravity 6c of the PET bottle 6 falling from the receiving portion 1. The plastic bottle 6 that has been detached from the temporary latching means 2 can be more reliably fed to the side opposite to the upper edge 30 (the side beyond the upper edge 30) of the sorting means 3, and The can 7 detached from the temporary latching means 2 can be more reliably dropped to the side not exceeding the upper edge 30 of the sorting means 3.
In the configuration 7 according to any one of the configurations 1 to 6, the receiving unit 1 biases the introduced plastic bottle 6 or can 7 in the direction of the latching portion 20 of the temporary latching means 2. Since the biasing means 15 is provided, the mouth area 63 of the plastic bottle 6 falling from the receiving part 1 can be brought into contact with the hooking part 20 more reliably.
In the configuration 8 according to any one of the configurations 1 to 7, the latching portion 20 of the temporary latching means 2 is located at a position where the mouth area 63 of the plastic bottle 6 falling from the receiving portion 1 should abut. Since the rod 20 is installed, the latching portion can be realized with a simple and low-cost mechanism.
Configuration 9 is any one of Configurations 1 to 7, wherein the temporary latching means 2 is used as the latching portion at a position where the mouth area 63 of the PET bottle 6 falling from the receiving portion 1 should come into contact. Since it has the vertical board 21 in which the upper edge part 20 is located, and the support shaft 25 which supports this vertical board 21 rotatably, the plastic bottle which falls from the receiving part 1 is latched by the temporary latching means 2. Thus, it is possible to more reliably exert the action of separating and rotating.

BRIEF DESCRIPTION OF THE DRAWINGS The apparatus structure of embodiment is shown, (a) is the front view typically shown through the inside of an apparatus, (b) is the same side view. FIG. 4A is a front view schematically showing the inside of an apparatus according to an embodiment different from that in FIG. 3. (B) is explanatory drawing which shows the structural example of the temporary latching means 2 different from the temporary latching means used by FIGS. 1-3, FIG.4 (a), (c)-(e) (B) The example of the vertical board 21 seen from the inner arrow C / D / E direction is shown, respectively.

Embodiments of the present invention will be described with reference to the drawings.
(1) Separation Principle of PET Bottle 6 FIG. 1 shows the principle of feeding a PET bottle (empty PET bottle) 6 onto the upper slope 351 of the ramp 35 beyond the upper edge 30 of the ramp 35. Here, the ramp 35 is formed by providing a flat plate with an inclination.
In the illustrated apparatus, the PET bottle 6 that rolls and falls by being placed on the loading ramp 10 of the receiving portion 1 is temporarily latched by a rod (bamboo chin) 20 that is a specific example of the temporary latching means 2. After that, rotate while leaving. As a result, the PET bottle 6 falls on the upper slope 351 beyond the upper edge 30 of the ramp 35 and is sent out from the lower part 353 to the outside.

  As described above, in order to “rotate the PET bottle 6 after being temporarily latched by the rod 20 and then released”, it is necessary to bring the mouth region 63 of the PET bottle 6 into contact with the rod 20. is there. As shown in FIG. 1 (c), the mouth area 63 includes a right end of the projecting ring 62 in the vicinity of the mouth 61 of the PET bottle 6 and a left end (tapered constriction of the cylindrical same-diameter portion of the PET bottle 6. The part that starts with). Here, the right end and the left end are based on FIG.

  In order to satisfy the requirement that the mouth region 63 of the plastic bottle 6 is brought into contact with the rod 20, in the example of FIG. 1, the size of the receiving unit 1 is used in a standard plastic bottle (500cc container; used for vending machines). Adapted). That is, the length of the receiving portion 1 in the left-right direction in FIG. 1A is set to be slightly longer than the length of the 500 cc container. In other words, the 500 cc container is long enough to accept with some play. For this reason, when a standard plastic bottle (500 cc container) is inserted, the vicinity of the front end side of the mouth area 63 (near the projecting ring 62) comes into contact with the rod 20, and as a result, the plastic bottle 6 rotates reliably. It falls on the upper slope 351 beyond the upper edge 30 of the ramp 35.

  On the other hand, for a plastic bottle slightly smaller than the standard size (350 cc), an elastic lip (elastic piece) 15 attached to the receiving portion 1 is used to place the small plastic bottle 6 in the direction of its mouth 61 (see FIG. 1 (a) to the left) and the mouth area 63 is adjusted so as to contact the rod 20.

  In order to confirm the effect of the elastic lip 15, an experiment was conducted using a 350 cc container. With the configuration in which the elastic lip 15 was removed, the success rate was about 30% (about 30% exceeded the upper edge 30 of the ramp 35 and the upper slope 351. On the other hand, in the configuration in which the elastic lip 15 is provided, the success rate is improved to about 70%. That is, about 70% dropped over the upper slope 351 beyond the upper edge 30 of the ramp 35.

  Although the success rate of about 70% is still insufficient, considering the fact that the effect of the elastic lip 15 has been confirmed, the material, elasticity, size, thickness, angle, etc. of the elastic lip 15 are adjusted, and the input ramp By adjusting the inclination angle of 10, the material of the slope, the length (rolling distance), etc., and by appropriately adjusting the falling distance etc. from the lower end of the receiving part 1 to the rod 20, It is considered that sufficiently high accuracy can be obtained.

  On the other hand, when the elastic lip 15 pushes the plastic bottle 6 too much, not the mouth area 63 but a portion near the bottom 65, that is, the cylindrical same-diameter portion of the plastic bottle 6 comes into contact with the rod 20. As a result, the force for rotating the shaft becomes insufficient, and the upper edge 30 of the ramp 35 cannot be crossed. For this reason, you may add the means to eliminate the malfunction by the excessive push of the plastic bottle 6 as needed.

For example, an appropriate stopper may be provided in front of the plastic bottle 6 pushed by the elastic lip 15, and the mouth area 63 may be guided so as to contact the rod 20 while the plastic bottle 6 is stopped. An example thereof is shown as a stopper 16 in FIG. In FIG. 4A, the stopper 16 has a curved surface shape, but is not limited to a curved surface, and may be a planar shape. In short, it is only necessary to prevent the plastic bottle 6 from being pushed too much and guide the mouth area 63 so that the mouth area 63 can slide against the rod 20 and can be hooked on the projecting ring 62.
In the above description, the function of the elastic lip 15 is described as “a function of pushing the plastic bottle 6”, but instead of the “function of pushing the plastic bottle 6” or together with the “function of pushing the plastic bottle 6”. The elastic lip 15 may be configured as a ramp so as to exhibit a “function of sliding the PET bottle 6 on the elastic lip 15 toward the mouth 61”.

  The elastic lip 15 and the stopper 16 are mechanisms for guiding the plastic bottle 6 and bringing the mouth area 63 into contact with the rod 20. Further, the projecting ring 62 of the plastic bottle 6 is rotated by being temporarily latched / removed by the temporary latching means 2 (the latching portion 20), so that the upper edge 30 of the ramp 35 can be more reliably exceeded. Good.

An example thereof is shown in FIGS.
In FIG. 1, the rod 20 is used as the temporary latching means 2, but in FIG. 4B, the vertical plate 21 in the vertical direction and the horizontal plate 22 connected in a horizontal direction from the lower end of the vertical plate 21. And a support shaft 25 that rotatably supports the distal end side of the horizontal plate 22, and a configuration in which the upper edge portion of the vertical plate 21 is formed as a hook portion 20 is a temporary hook means 2.

The temporary latching means 2 of FIG.4 (b) functions as follows.
The PET bottle 6 in which the mouth area 63 abuts on the upper edge 20 (/ 201) of the vertical plate 21 slides on the upper edge 20 (/ 201) while falling, and the end portion of the mouth area 63 When the projecting ring 62 reaches the upper edge 20, the projecting ring 62 is temporarily latched by the upper edge 20.
On the other hand, the vertical plate 21 and the horizontal plate 22 integrated with the vertical plate 21 are pushed by the PET bottle 6 as the PET bottle 6 is dropped, and rotate in the direction of the arrow r about the support shaft 25 as an axis. Is stopped by the stopper 23 (when the vertical plate 21 faces horizontal).

In the middle of the rotation in the direction of the arrow r or when the rotation is stopped by the stopper 23, the PET bottle 6 is separated from the upper edge portion 20 of the vertical plate 21 and lower left (lower left in FIG. 1A). Rotate in response to the force to the top, fall over the upper edge 30 of the ramp 35 and drop onto the upper slope 351.
On the other hand, the temporary latching means 2 from which the plastic bottle 6 is detached is biased by a spring (not shown) and rotates in the direction of the arrow s, so that the original position (the vertical plate 21 is in the vertical direction and the horizontal plate 22 is in the horizontal direction). When it returns to the (facing position), it is stopped by the stopper 24. The spring is a spring having such a force that the rotation in the direction of the arrow r pushed by the plastic bottle 6 is allowed and the vertical plate 21 and the horizontal plate 22 can be rotated in the direction of the arrow s after the PET bottle 6 is detached. I just need it.

In the above, the rotation with the support shaft 25 as the axis may be configured to rotate the support shaft 25 integrally with the horizontal plate 22 (= both ends of the support shaft 25 are rotatably supported on the housing side). The shaft 25 may be fixed and the horizontal plate 22 may be rotated around the shaft 25.
Further, the upper end edge of the vertical plate 21 may be a horizontal straight line as shown in FIG. 4 (e), but it also serves as a latching portion 20 that is inclined toward the center of the upper end edge 20 as shown in FIG. 4 (d). The guide portion 201 may be configured as shown in FIG. 4C, and at the tip of the guide portion 201 (center position in FIG. 4C), the diameter of the mouth portion 61 of the PET bottle 6 is approximately the same. You may provide the latching | locking part 20 which comprises a circular arc.

  In order for the PET bottle 6 to “can exceed the upper end edge 30 of the sorting means 3”, the bottom portion 65 of the PET bottle 6 that rotates to the lower left (lower left in FIG. 1A) while rotating, and the ramp 35 It is necessary to secure a gap t (FIG. 4A) between the upper edge 30 of the two. In other words, the height 30h of the upper edge 30 of the plate-like portion of the sorting means 3 (slope 35 / partition wall 36 (see FIG. 4A)) is lower than the lowest end 65b through which the bottom 65 of the PET bottle 6 passes. It is necessary to set it lower by at least the gap t. Here, t is a gap that can prevent the interference between the bottom 65 of the plastic bottle 6 when it passes above the upper edge 30 of the sorting means 3.

  However, the bottom end 65b through which the bottom portion 65 of the PET bottle 6 passes is the falling locus of the PET bottle, the rotation angle when reaching the top edge 30 of the plate-like portion (slope 35 / partition wall 36), and the length of the PET bottle 6. These are determined by, for example, “the material, elasticity, size, thickness, angle, etc. of the elastic lip 15, the inclination angle of the feeding ramp 10, the material of the slope, the length (rolling distance), etc. In addition to the “falling distance from the lower end of the rod 20 to the rod 20”, the position of the latching portion (the rod 20 / the upper edge portion 20 of the vertical plate 21) in the lateral direction (left-right direction in FIG. 1A), Appropriate values are obtained by repeating the experiment using a container to be separated, such as a 500 cc container or a 350 cc container, because it is affected by the surface shape, position, material, etc., as well as the shape and center of gravity of the PET bottle. Considered to be able to ask .

(2) Principle of processing of empty can 7 FIG. 2 shows the principle of dropping the empty can 7 so as not to cross the upper edge 30 of the ramp 35, in other words, without feeding it onto the upper slope 351 of the ramp 35. The configuration of the apparatus is the same as in FIG.
In the illustrated apparatus, the can 7 that rolls on the charging ramp 10 and falls from the receiving portion 1 by being placed on the charging ramp 10 of the receiving portion 1 is a rod (bamboo) that is a specific example of the temporary latching means 2. It is bounced back in contact with the chin 20 and falls while rotating.

  As shown in the figure, the left and right positions of the center of gravity 7c of the empty can 7 at the time of contact with the rod 20 (here, “left and right” are the left and right with reference to FIG. 1 (a) and FIG. 4 (a); ) Is on the right side of the upper edge 30 of the ramp 35 and is not on the upper slope 351 side of the ramp 30. For this reason, even if the can 7 comes into contact with the upper edge 30 of the ramp 35 during the fall, the can 7 does not enter the upper slope 351 side of the ramp 35 but falls as it is, and the can ramp (second (Slope) 4 and sent to the outside. When experimenting with empty cans 7 of various lengths, 100% of them all did not enter the upper slope 351 side, dropped and sent out from the can ramp 4 to the outside.

(3) Left and right positions of the upper edge 30 of the ramp 35 As is clear from the above “(2) Principle of processing of the empty can 7”, the upper edge 30 of the ramp 35 (= the upper edge 30 of the partition wall 36; FIG. 4A). The rightmost position of (see) can be defined as a position immediately below the center of gravity 7c of the empty can 7 from the request that “the empty can 7 is dropped without being sent to the upper slope 351 side of the ramp 35”. Accordingly, a desirable allowable range of the position of the upper edge 30 in the left-right direction is a region on the left side of the empty can 7 immediately below the center of gravity 7c. Even if the upper edge 30 of the ramp 35 and the partition wall 36 is set in a region on the right side of the position directly below the center of gravity 7c of the empty can 7, it is completely impossible to immediately drop the empty can directly onto the can ramp 4 as it is. Not that.

On the other hand, as apparent from “(1) Principle for separating PET bottles 6”, the leftmost end position of the upper end edge 30 of the ramp 35 (= the upper end edge 30 of the partition wall 36) is “ It can be defined as a position immediately below the rod (holding portion) 20 from the request of “urging to be fed onto the inclined surface 351”. Therefore, a preferable allowable range of the position of the upper edge 30 in the left-right direction is a region on the right side of the rod (the latching portion) 20. Furthermore, since it is possible to define the position directly below the center of gravity 6c of the plastic bottle 6 from the request that “the plastic bottle 6 is urged to be surely fed onto the upper slope 351 of the ramp 35”, the upper end A more preferable allowable range of the position of the edge 30 in the left-right direction is a region on the right side of the plastic bottle 6 immediately below the center of gravity 6c.
Even if the upper edge 30 of the ramp 35 and the partition wall 36 is set in a region on the left side of the position immediately below the rod (holding portion) 20, the PET bottle 6 can be immediately fed onto the upper slope 351 of the ramp 35. It is not impossible at all.

From the above, the desirable range of the horizontal position of the upper edge 30 of the ramp 35 of the sorting means 3 (= the desirable range of the horizontal position of the upper edge 30 of the partition wall 36) is
(A) “Right side from the position directly below the rod (holding portion) 20 to the left side from the position directly below the center of gravity 7c of the empty can 7” (“p” in FIG. 4A);
And more preferably
(B) “Right side from a position directly below the center of gravity 6c of the plastic bottle 6 to a left side from a position just below the center of gravity 7c of the empty can 7” (“q” in FIG. 4A);
It is.

From the steel can opening 5, the steel can is delivered to the steel can receiving portion 98.

  Further, in order to prevent the steel can 8 from being attracted to the magnet 52 and stopping, the resin sheet piece 54 is suspended from the upper edge of the steel can opening 5.
