Although it is a shape developed on a plane, the magnetic field changes in the direction indicated by the arrow in FIG. 5, and as a result, the glass waste bottles that are transferred through the transfer path portions 81a, 81a ′, 81b, 81b ′ due to vibration are mainly In non-ferrous scraps such as aluminum scrap h, an induced current is generated by the magnetic flux of the linear motor 82 that changes in the direction of the arrow, and the resulting magnetic flux interacts with the moving magnetic field of the linear motor 82. Transferred in the direction of arrow e. Of course, this is being transferred by vibration, and is thus transferred in an oblique direction. As a result, the openings 84a, 84 formed adjacent to the side wall of the trough 61 are connected to this downstream side.
The waste bottle D that has fallen into the inside b and is not affected by the magnetic field of the linear motor 82 is configured to be transferred to the downstream side through the transfer path portion 85 between them.

And the diameter L2 of the small diameter bottle D3 is larger than the diameter of the small diameter bottle D3.

Next, the details of the aligning device 6 will be described with reference to FIGS.

The medium diameter bottle D2 is sorted by the large diameter sorting section 5D located on the most downstream side of the upstream conveyor device 5 and is supplied to the aligning device 6. It is assumed that the waste bottle D1 of No. 1 is supplied to the color sorter by the same aligning device as described below and similarly sorted by color.
The aligning device 6 comprises a moving belt conveyor 100 and an aligning conveyor 105, and the belt 103 of the moving belt conveyor 100 is wound around a driving roller 120 and a driven roller 121 as shown in FIG. The outer race side of the bearing that is supported on the ground is integrated by a horizontal bar 104, and the drive rod 106 of the air cylinder device 107 is connected to the center of the bearing through a mounting plate 105. It should be noted that on both sides of the belt 103, in order to stably support the waste bottle D2 and transfer it in the direction indicated by the arrow, ridges 103a and 103b are formed on both side edge portions. The air cylinder device 107 has a predetermined stroke in the extending direction of the drive rod 106 and a predetermined order in the s direction by a control device (not shown).
It is configured to drive 06. Large diameter sorting section 5D

2H are provided, and these gates 102A to 102A are provided.
When the drive rod 106 is moved to the step shown in FIG.
At 0, it is configured to move from above to below and from below to above.

Next, referring to FIGS. 11 and 12, FIG.
Details of the sorting mechanisms 110A and 110B will be described. Since they have the same configuration, only 110A will be described. This is mainly the belt conveyor 11
1, a driving roller 112 for driving the driving roller 112 (a belt is wound between a driven roller (not shown)), and one side of the belt conveyor 111. Guide chutes 121, 122 and 12 for guiding the waste bottles to be sorted into
3 are connected to each other, and one end of each of the belt conveyors 111 is provided on the other side of the shafts 113a, 114a and 1 in correspondence therewith.
Gate plates 113, 11 pivotally attached to the stationary portion at 15a
4, 115 are provided, which are configured to receive the identification signal of the color sorter 90 on the upstream side and take the position shown by the solid line or the one-dot chain line by the drive rod of the air cylinder (not shown).

The waste bottle sorting apparatus according to the embodiment of the present invention is constructed as described above, and its operation will be described below.

The waste mainly consisting of the waste bottles in the reversing machine 2 is shown in FIG.
It is supplied with the gate 32 opened in the container 31 in the above, but these are generally in the form of cardboard boxes with their mouths facing upward, or in a state where multiple containers are contained in a plastic bag, or for each bottle. Supplied with the top facing up. After closing the gate plate 32, the gate plate 32 is rotated about the shaft 34, for example, 180 degrees in the clockwise direction, and then the gate plate 32, which is now below, is opened again, but at this time, the open position is gradually taken. As a result, the waste bottle is gently discharged onto the trough 36 of the vibrating feeder 35 disposed below this with its mouth inclined obliquely downward, and the trough 36 is stably transferred to the right in the figure by the vibration v. It It should be noted that, in some cases, instead of 180 degrees, it may be rotated about 150 degrees from the position shown in the figure and discharged obliquely. When empty, the gate plate 32 is closed, and now the gate plate 33 above is opened and a waste bottle is supplied.

These waste bottles are supplied to the bag crushing machine 3 in FIG. 1, where the cardboard box and the vinyl bag are ruptured by a blade not shown, and since these are light, they are sucked into the air suction port arranged above them. Also, the film is discharged to the film storage box 13 through a guide pipe (not shown). Thus, the cardboard box and the waste bottles containing these are removed and supplied to the PET bottle sorter 4. In FIG. 3, the waste B mainly consisting of waste bottles is supplied from the bag breaking machine 3 to the supply port 51a of the wind separator, but these fall on the inclined plate 54, slide down there, and during this drop. The PET bottle C having a relatively small specific gravity is blown off to the left in the figure and is led out from the first outlet 51b to the guide pipe, and the PET bottle C passes through the guide pipe. And is discharged into the PET bottle storage box 14 shown in FIG. The waste D mainly consisting of waste bottles discharged from the second discharge port 51c of the wind separator is discharged to the end of the trough 61, which is connected to the base block 63 by the pair of left and right leaf springs 62. However, the vibration n of the trough 61 causes the trough 61 to be transferred to the right in the figure.

Next, when it reaches the iron separating portion 5A, as shown in FIG. 4, a magnetic separator 70 is disposed immediately above the trough 61 in this portion, which has a known structure. Since the belt 75 is wound around the driving roller 73a, the driven roller 73b, and the guide rollers 74a and 74b as shown in the drawing, the permanent magnet 76 is disposed in the vicinity of the running portion. The iron dust f mixed with the waste bottle D in the trough 61 receives the magnetic attraction force in the trough 61, and the belt 7 receives the magnetic flux.
5 is sucked by the belt 5, is transferred to the right in the figure together with the belt 75, and is discharged to the guide pipe 77 when it leaves the range of the magnetic field of the permanent magnet 70. These are discharged into the iron-containing box 15 through the guide pipe 18 in FIG. In this case, the scrap iron f has a smaller capacity than the waste bottles D, and therefore the jump amount is much larger even if the same vibration force of the trough 61 is received. The belt D5 is attracted to the belt D5 by being attracted thereto and can be easily guided to the guide pipe 77. Note that FIG. 4 shows an electromagnet 72 in which a coil is wound on a base block 63, and a movable core 71 is fixed to the bottom wall portion of the trough 61 with a gap therebetween, whereby the electromagnet 72 in FIG. The trough T, which is a movable part of the entire conveyor device 5, is vibrated in the direction of m.

Next, the non-ferrous dust separating section 5B shown in FIG. 5 is reached. The linear motor 82 is a well-known spreader of a stator of an induction motor, and the AC voltage applied to this coil is used. A magnetic field is generated in the direction of arrow e, which causes an induced current to flow in non-ferrous scraps, such as aluminum scraps h, which are transferred by vibration thereover,
Due to the interaction between the magnetic flux and the magnetic flux generated by the linear motor 82, the transfer force indicated by the arrow e is received, and thus the trough 61
Are transferred along the both side wall surfaces of and fall into the grooves 84a and 84b. These are discharged to the non-ferrous metal containing box 56 through the guide pipe 19 in FIG. The waste D mainly consisting of waste bottles is vibrated in the transfer path 85 without being affected by the moving magnetic field of the linear motor 82, and is guided to the downstream side. In order to reliably guide the waste bottle D to the transfer path 85, the width of the grooves 84a and 84b should be made smaller than the diameter of the smallest waste bottle, or the transfer path portion 8
1a, 81a ', 81b, 81b' are separated by partition walls 83a, 83
You may make it incline downward toward b, and the driving force shown by the arrow e of the linear motor 82 is the transfer path part 81a,
81 a ′, 81 b, 81 b ′ is stronger than the transfer force toward the center due to the gravitational action due to the inclination, and the aluminum scrap h is surely discharged into the grooves 84 a and 84 b, and the waste bottle D is vibrated on the transfer path 85 by vibration. Can be led to the downstream side.

In FIG. 7, since the screen 90 is stretched in the sediment separating section 5C, all the waste bottles D are transferred on the sieve by vibrating and the sediment is passed through the mesh of the screen 90 and sieved. As the bottom, it falls downward and passes through the guide pipe 20 in FIG.
Is discharged to. Next, the bottle diameter selection section 5D shown in FIG. 8 is reached. Here, the distance L1 between the uppermost strips 91, 91 is larger than the diameters of the medium diameter bottle D2 and the small diameter bottle D3. The large diameter bottles D2 and the small diameter bottles D3 all pass through here and fall downward, and only the large diameter bottle D1 is received by a pair of adjacent strips 91 as indicated by the one-dot chain line and is transferred downward by vibration. Further, the medium-sized bottle D2 is received by the pair of intermediate strips 92 close to each other and is transferred by vibration to the downstream side, and the small-sized bottle D3 is shown by the one-dot chain line by the pair of adjacent strips 93 at the bottom. It is received and transferred to the downstream side by vibration. The rubber members g1, g2, and g3 attached to the upper ends of the strips 91, 92, and 93 are used for the large diameter bottle D1 and the medium diameter bottle D2.
Also, since the small diameter bottle D3 is received and transferred by vibration, the small diameter bottle D3 is not damaged even if the swing is relatively large, the noise is small, and it can be smoothly transported to the downstream side.

In the diameter selection section 5D, the trough 94
Is much larger than the depth of the upstream trough 61, but is integrally formed.

Next, referring to FIG. 9, in the bottle diameter selection section 5D, the large diameter bottle D1 and the medium diameter bottle D2 are processed as described above.
The small diameter bottle D3 and the small diameter bottle D3 are sorted and supplied to the respective aligning apparatuses. To explain the operation of the medium diameter bottle D2 aligning apparatus, the moving conveyor 100 is at the position shown in FIG. A pair of adjacent strips 92, 9 facing the gate 102B and corresponding to the gate 102B.
Medium-sized bottle D2 that has been received by 2 and transferred by vibration
Passes below the now open gate 102D,
As shown in the figure, it is stably supported on the belt 103 of the belt conveyor 100 by the ridges 103A and 103B on both sides.
Transferred to the right in the figure, the single-row belt conveyor 10
5, and is supplied to the color sorter 9 on the downstream side. The belt conveyor 100 is then moved one pitch downward from the position shown in the drawing to move the belt 1
03 stops at a position facing the gate plate 102E. Note that, in FIG. 9, a medium diameter bottle is not shown in the medium diameter bottle transfer path formed by the adjacent strips 92 corresponding to the gate plate 102E.
It is assumed that the vehicle comes into contact with and is stopped. Belt conveyor 10
0 stops at a position facing the gate plate 102E, and the gate plate 102E moves upward after a predetermined time elapses.
0 is vibrated and transferred to the right and is then transferred to the alignment belt conveyor 105. Immediately thereafter, the belt conveyor 100 further moves one pitch in the s direction, stops at a position facing the gate plate 102F, and performs the same operation as described above, but the belt conveyor 100 moves one pitch in the s direction. Gate plate 1
Instead of moving at a predetermined pitch opposite to 02A to 102H, when the supply speed of the medium diameter bottle D2 is smaller, a limit switch is provided on the gate plates 102A to 102H and this is pushed by the medium diameter bottle to turn on. You may make it stop facing this gate plate only when it is. In this case, the belt conveyor 100 is not limited to one pitch, and when the drive rod 106 is moving forward as described above, the belt plate is closest to the gate plate that operates the limit switch in this direction. It suffices if they are opposed to each other and stopped. Furthermore, the gate plate 10
When it reaches the position facing 2H, it may return to the position facing the uppermost gate plate 102A all at once in FIG. 9, but it may be a predetermined pitch from the gate plate 102H to the gate plates 102A to 102H, or recently. The limit switch may be brought into contact with the gate plate to stop the limit switch at a position facing the gate plate.

The large-diameter bottle D1 received on the uppermost strip plate 91 shown in FIG. 8 is also supplied to the color sorter on the downstream side in a single row by the same configuration as in FIGS. 9 and 10. .

Next, in FIG. 8, the small-diameter bottle D3 received by the lowermost strip 93 and transferred by vibration is guided by the guide pipe 2 on the vibrating parts feeder 7 shown in FIG.
The vibrating parts feeder 7 is constructed in a known manner, and a spiral track is formed on the inner peripheral wall of the bowl, and the vibrating parts feeder 7 is transferred by torsional vibration on the track. However, due to its known operation, the small-diameter waste bottle D3 is transferred along the spiral track and with its longitudinal direction directed in the transfer direction, and the discharge end of this track directs the single bottle to the longitudinal direction in the transfer direction. It is discharged toward the alignment belt conveyor.

As described above, all the waste bottles, that is, the large diameter bottle D1, the medium diameter bottle D2, and the small diameter bottle D3 are supplied to the large diameter bottle color selectors 9 and 10 (not shown).

Although various types of color sorters 9 and 10 are known, for example, color detection is performed by the color signal of a signal picked up by a video camera of a color television developed by the present applicant. A drive signal based on the color detection signal is supplied to a gate drive air cylinder selector (not shown) of the sorting machines 110A and 110B on the downstream side. The waste bottles whose colors are identified by the color sorters 9 and 10 for each diameter are introduced into the sorting mechanisms 110A and 110B.
Now, the medium-sized bottle will be described with reference to FIGS. 11 and 12. When the color sorter 9 determines that the medium-sized bottle is colorless, for example, a shochu bottle, the medium-sized bottle D21 is a colorless bottle storage box. It should be discharged to 124, but at this time, none of the gate plates 113, 114, and 115 is driven, and is in the shielded position. Therefore, the colorless bottle D21 coming from the upstream side is the gate plate 113, and FIG.
In Fig. 1, the open position is shown by a chain line, and the open position is shown by a solid line.
13 also shows a closed position, and the medium-sized bottle D21 guided by the gate plate 113 and transferred by the belt conveyor 111 is guided by this and rolled on the guide chute 121 to be stored in the colorless bottle storage box 124. Is discharged.

Next, when the color-selected medium-sized bottle D22 is brown like a beer bottle, a signal indicating that it is brown is supplied to the driving devices of the gate plates 113, 114 and 115. However, in this case, the air cylinder (not shown) connected to the gate plate 113 on the most upstream side is driven to take the open position shown by the solid line, but the gates of the other gate plates 114 and 115 remain closed. . As a result, the medium-sized bottle D22 conveyed by the belt conveyor 111 is guided by the second gate plate 114 from the upstream side and drops onto the guide chute 122 as shown in the figure, and slides there to slide in the brown bottle storage box. It is arranged at 125. Further, when the medium-sized bottle D23 supplied next is judged to be black (for example, whiskey bottle), the two gate plates 113, 114 on the upstream side are driven by the air cylinder device (not shown) to take the open position. Further, the gate plate 115 on the most downstream side remains in the closed position. As a result, the medium-sized bottle D23 transferred by the belt conveyor 111 is guided by the gate plate 115 and guided by the guide chute 1.
13 is slid and discharged into the black bottle storage box 126.

The large-sized bottles are similarly sorted, and the large-sized bottles are color-selected and discharged into the colorless bottle storage box, the brown bottle storage box, and the black bottle storage box, respectively.

Although the configuration and operation of the embodiment of the present invention have been described above, as is clear from the above, the waste bottle sorting apparatus of the present embodiment can be fully automated and color-coded bottles of each diameter. it can. Also, other miscellaneous debris such as iron debris, aluminum debris, earth and sand, etc. are removed before being applied to the color sorter, so that the color of the bottle is reliably selected by the color sorter, and no malfunction occurs. .

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiments, a conventionally known wind separator was used as the PET bottle sorter 4. However, by omitting this, the size of the air suction port in the bag breaking machine 3 and its suction force are appropriate. When set to 1, not only the plastic bag and the corrugated cardboard chips but also the PET bottle having a small specific gravity can be sucked together with these and discharged into the films storage box 13. In this case, of course, the wind sorter 4 as a PET bottle sorter can be omitted.

Further, in the above embodiment, the trough T in which the iron separating section 5A, the non-ferrous separating section 5B, the earth and sand separating section 5C, and the large diameter selecting section 5D are integrated in one belt conveyor device 5.
Although they are provided inside or close to them, they may be provided separately. That is, a vibrating feeder with a magnetic separator installed above, a vibrating feeder with a linear motor attached to the bottom wall of a trough, a vibrating screener for sieving for selecting soil and sand, and a vibrating conveyor for selecting large diameters. You may make it arrange | position and arrange | position each as a separate body, and you may make it isolate | separate ferrous metals, nonferrous metals, and earth and sand refuse in the same order as the said Example.

Further, in the above embodiment, the linear motor 82 is used for separating non-ferrous dust, but instead of this, a known belt conveyor type non-ferrous metal separating device, that is, a driving roller and a larger diameter than this is used. Yes A belt is wound around a cylindrical body made of non-metal, for example, plastic, and the belt is run at a first running speed, and is concentric with the inside of a driven roller made of non-metal, and a permanent magnet on the outer periphery. One side is N pole,
The rotating body mounted by alternately changing with the S pole is rotated in the same direction at a rotation speed much higher than that of the driven roller on the outer peripheral side of the rotating body, whereby the non-ferrous metal, for example, aluminum reaching above is rotated. An alternating current of permanent magnets attached to the outer periphery of the rotating body causes an induced current to flow through the aluminum scrap, and the interaction between the resulting magnetic flux and the magnetic flux due to the rotation of the permanent magnets causes a vertical component to be received from the discharge end of this belt. This is a conveyor that separates non-ferrous metal waste in a splashing manner, but such a non-ferrous metal separating device is also applicable to the present invention.

In the above embodiment, the aligning device 6 is provided for the large diameter bottle and the medium diameter bottle as shown in FIGS. Although the alignment belt conveyor 105 was used, instead of this, the diameter of the balls of the vibrating parts feeder 7 used for the small diameter bottle D3 was determined for the large diameter bottle and the medium diameter bottle. Known feeders are small ones for electronic parts or large iron ingots such as billets.) These are used for large diameter bottles and medium diameter bottles, respectively. The large diameter bottle or medium diameter bottle, which was supplied all at once into the ball only by the vibrating parts feeder, is moved along the spiral track formed on the inner peripheral wall of the ball, and By the action, directed in the longitudinal direction in the transport direction from the discharge end of the track, and articulated thereto in a row, and then supplied to the same belt conveyor and aligned belt conveyor 8, as shown in FIG.

In the above embodiment, the color sorters 9, 10 are used.
As the above, the image pickup signal of the video camera developed by the present applicant was used, but instead of this, a reflection type color sensor which has been conventionally used in a component sorting device of a vibrating parts feeder is used, and white light is emitted. Alternatively, the color may be selected according to the level of reflected light from the bottle. Alternatively, the colors may be selected by analyzing the transmitted light.

Further, in the above embodiment, the waste bottles are sorted into colorless, brown and black. However, the waste bottles may be sorted into a larger number of colors such as blue-green (like a bottle of vinegar) and other colors. You may

Further, in the above embodiment, the diameter is classified into the large diameter bottle, the medium diameter bottle and the small diameter bottle by the sorting vibration conveyor section 5D. However, the large diameter bottle, for example, one bottle is a medium diameter bottle. Since the amount is much smaller than the amount of small bottles,
These may be manually removed by a worker separately.

Further, in the above embodiments, the three-stage strips 91, 92 and 93 in the height direction are used to classify the large diameter bottle, the medium diameter bottle and the small diameter bottle, but instead of this, Although the levels are the same, a group of strips arranged linearly from the upstream side to the downstream side may be provided so that the distance between the strips gradually increases toward the downstream side.

Further, in the above embodiment, the electromagnet driving unit is provided to drive the trough T which is the movable unit of the conveyor device 5 provided with the various dust separating units, but instead of this, the motor and the crank driving unit are provided. A linear vibrating force may be generated by a crank type vibrating mechanism or a pair of vibrating motors to vibrate the trough. All other known vibration mechanisms can be applied, but when the iron dust separating portion 5A, the non-ferrous dust separating portion 5B, the earth and sand separating portion 5C, and the large diameter sorting portion 5D are separately provided as described above. Alternatively, the type of the vibration exciter may be changed according to the vibration required by each separating action. In this case, the magnitude of the exciting force, the frequency of the exciting force, the vibration angle, etc. can be changed. For example, in the earth and sand sorting unit, it is possible to increase the sieve sharpness by increasing the vibration angle as is known.

Further, as the magnetic separator, a drum type magnetic separator can be applied instead of the belt type one described above.

Further, although the reversing machine 1 and the bag-breaking machine 3 are provided on the most upstream side in the above embodiments, they may be omitted depending on the method of supplying the waste bottles to the PET bottle sorter. Further, a vibration sorter 200 as shown in FIG. 13 may be applied as the sorting device. FIG. 13 shows a part of this device, but as a whole, it vibrates in the direction of arrow 201, and gate plates 203, 204 and 205 are arranged at a predetermined pitch in the transfer path 202. , Its pivot shaft 203A by an air cylinder device (not shown),
Positions indicated by solid lines and alternate long and short dash lines can be selectively taken around 204A and 205A. In FIG. 13, the gate plate 203 is in the open position and the gate plates 204 and 205 are in the closed position. . That is, normally, these gate plates 203, 204 and 205 are in the closed position, in which case the medium diameter bottle D2 vibrates above these gate plates 203, 204 and 205 which are part of the transfer path 202. Is transferred to the downstream side by means of the gate plates 203, 20 when sorting is performed.
4 and 205 are selectively held in the open position. That is, when the medium diameter bottle D21 is colorless, the gate plate 2
03 takes the position shown by the solid line, and the medium diameter bottle D21 that has arrived from here on the upstream side has the gate plate 20 in the open position.
3 is slid as shown in the drawing, and discharged into the colorless bottle storage box 124. Also, a medium-sized bottle D22 coming from the upstream side
If is brown, the gate plate 203 is closed, but the gate plate 204 is in the open position as indicated by the alternate long and short dash line. As a result, when it is transferred on the gate plate 203 by vibration and reaches the position of the gate plate 204, it slides on the gate plate 204 in the open position and falls into the brown bottle storage box 125. The same is true for black brown bottles.

As described above, according to the waste bottle sorting apparatus of the present invention, the diameters of waste bottles can be sorted completely automatically, and the bottles of each diameter can be surely sorted for each color. It is possible to sort waste bottles of each diameter for each. Therefore, regarding waste bottles of each color of each diameter, you can use them as raw bottles, or
Alternatively, it is possible to appropriately select whether to destroy the cullet and melt it for recycling. In case of melting with cullet, if the bottles with different colors are mixed, the desired glass product cannot be obtained.
With the present invention, there is no such fear.
