It is the conceptual diagram which showed the volume reduction roller shown.

  The container collection device collects containers such as empty cans and empty plastic bottles after the beverage has been drunk and collects them. As shown in FIG. 1, the main body cabinet 1 and the front opening of the main body cabinet 1 are collected. It has the outer door 2 which provided the part so that closure was possible.

  As shown in FIG. 2, the inside of the main body cabinet 1 is divided into an upper region and a lower region by a partition plate 1A. The upper region constitutes a machine room 1B, and the lower region constitutes a recovery chamber 1C. .

  As shown in FIGS. 2 and 3, the machine room 1 </ b> B is provided with a loading port unit 3, a container transport unit 4, a reading unit 5, a sorting unit 6, a sending unit 7, and a volume reduction processing unit 8. .

  The inlet 3 is attached to the inner surface of the upper part of the outer door 2 and has an inlet 10 for inserting a container 9 such as an empty can or an empty plastic bottle, as shown in FIGS. . A door body 11 that opens and closes the inlet 10 is slidably attached to the inlet 3. A motor 12 that opens the door 11 is attached to the insertion port 3. A pinion gear 13 is fixed to the drive shaft of the motor 12, and a rack 14 that meshes with the pinion gear 13 is attached to the door body 11. Therefore, when the motor 12 is rotated counterclockwise in the closed state of the insertion port 10 shown in FIG. 5, power is transmitted to the door body 11 through the pinion gear 13 and the rack 14, and the door body 11 is moved to the left.

On the other hand, when the motor 12 is rotated clockwise in the open state of the insertion port 10, the door body 11 moves to the right and closes the insertion port 10 as shown in FIG. 5.

  As shown in FIG. 6, the auxiliary door 15 is slidably attached to the door 11. Between the door body 11 and the auxiliary door body 15, a spring 16 that urges the auxiliary door body 15 in a direction protruding from the door body 11 is stretched. In addition, a switch 17 that outputs a signal when the auxiliary door body 15 moves backward with respect to the door body 11 is attached between the door body 11 and the auxiliary door body 15. For this reason, when a foreign object such as a finger is interposed in the insertion port 10 during the closing operation of the door body 11, the foreign object comes into contact with the auxiliary door body 15, so that the auxiliary door body 15 retreats against the urging force of the spring 16. Moving. When the auxiliary door 15 moves backward with respect to the door 11, the switch 17 outputs a signal and determines that the closing operation of the door 11 is prevented. Then, the closing operation of the door body 11 is interrupted, and the motor 12 is rotated counterclockwise to open the door body 11.

  As a result, when a foreign object such as a finger is present in the insertion port 10 during the closing operation of the door body 11, the closing operation of the door body 11 is interrupted and the door body 11 is opened. Even if it is mistaken, a situation where foreign matter is caught between the insertion port 10 and the door body 11 is prevented, and there is no possibility that both the foreign matter and the door body 11 are damaged.

  As shown in FIG. 3, a slot sensor composed of a light projecting element 18 and a light receiving element 19 is disposed in the depth of the slot 3. The insertion port sensor outputs a signal when the light irradiated from the light projecting element 18 to the light receiving element 19 is interrupted, and can detect whether the container 9 has been inserted and whether the container 9 has been charged.

  In the back of the input port sensor, a container transport unit 4 communicating with the input port 10 extends toward the back side of the machine room 1B. The container transport unit 4 transports the container 9 introduced from the insertion port 10 to the back of the machine room 1B, rotates the container, and measures the weight of the container.

  The container conveyance part 4 has the housing | casing 20 and a pair of guide roller 21, as shown in FIG. The housing 20 is attached to the partition plate 1A. The pair of guide rollers 21 supports the container 9 introduced from the insertion port 10 between them and rotates the supported container 9, and a drive mechanism 22 disposed on the back side of the housing 20. Further, it is detachably attached to a support mechanism 23 disposed on the front side of the housing 20.

  One end 210 of the guide roller 21 is provided with a mounting hole 211 for mounting on the drive mechanism 22 and a groove (not shown) across the mounting hole 211, and the other end 212 has A mounting hole 213 that gradually expands from the end 212 of the guide roller 21 to the inner side of the guide roller 21 is formed for mounting on the support mechanism 23.

  A low friction surface 21 a and a high friction surface 21 b are formed on the outer peripheral surface of the guide roller 21 along the axial direction. For example, the portion that becomes the low friction surface 21a exposes vinyl chloride, which is the material of the guide roller 21, and the portion that becomes the high friction surface 21b is pasted with rubber.

  As shown in FIGS. 9 and 10, the drive mechanism 22 has a pair of drive shafts 24 on which the guide rollers 21 are mounted, and a motor 25 that rotates these drive shafts 24. The drive shaft 24 is rotatably attached to the housing 20, and a pin 241 is fixed to the end portion 240 of the drive shaft 24 on the guide roller mounting side so as to cross the drive shaft 24. A timing pulley 26 is fixed to an end 242 of the drive shaft 24 opposite to the guide roller mounting side. A timing pulley 27 is fixed to the drive shaft of the motor 25, and a timing belt 28 is wound around these timing pulleys 26 and 27. For this reason, when the motor 25 is rotated, the drive shaft 24 rotates in the same direction.

  As shown in FIG. 9, the support mechanism 23 includes a pair of support shafts 29 and a flange 30 attached to the support shaft 29. The support shaft 29 is for mounting the guide roller 21 and is rotatably attached to the housing 20. The flange 30 is slidable with respect to the support shaft 29 and is urged by a spring 31 toward the guide roller mounting side end 291 of the support shaft 29.

  When the guide roller 21 is mounted between the drive mechanism 22 and the support mechanism 23 configured as described above, the shaft core of the support shaft 29 and the shaft core of the mounting hole 213 are aligned to resist the biasing force of the spring 31. After mounting one end of the guide roller 21 on the support shaft 29 so as to push the flange 30 in, the shaft core of the mounting hole 211 of the guide roller 21 and the shaft core of the drive shaft 24 are aligned, and the pin 241 is a groove (see FIG. (Not shown).

  When the guide roller 21 is mounted between the drive mechanism 22 and the support mechanism 23, the pin 241 fits into a groove (not shown), the drive shaft 24 and the guide roller 21 are integrated, and the flange 30 is urged by the urging force of the spring 31. And the guide roller 21 are integrated. For this reason, when the motor 25 is rotated, the pair of guide rollers 21 rotate in the same direction.

  The support mechanism 23 is provided with an attachment / detachment restricting means 32 for restricting attachment / detachment of the guide roller 21 between the housing 20 and the flange 30. The attachment / detachment restricting means 32 restricts the movement of the flange 30 by restricting the gap between the housing 20 and the flange 30 and is removed when the container collection device is stopped to allow the guide roller 21 to be attached / detached.

  As shown in FIG. 3, a container detection sensor for detecting the container 9 is disposed above the guide roller 21 and includes a light projecting element 33 and a light receiving element 34. The container detection sensor outputs a signal when the light irradiated from the light projecting element 33 to the light receiving element 34 is blocked.

  A conveying means 35 is disposed between the pair of guide rollers 21. As shown in FIG. 11, the conveying means 35 includes a roller 36 that is rotatably disposed on the front side of the housing 20, a roller 37 that is disposed at the back, a roller 39 that is fixed to a motor 38, and these rollers. And a conveyor belt 40 stretched between them. A flexible rib 40 a is formed on the conveyance surface of the conveyance belt 40. The rib 40a is formed at a position where the conveying belt 40 is equally divided. The rib 40a contacts the charged container 9, and conveys the container 9 to the back. When the transported container 9 is transported to the innermost position, the rib 40a bends and passes through the lower side of the container 9 to circulate.

  The conveying means 35 further has a belt position detection sensor 40b. The belt position detection sensor 40b detects the position of the conveyor belt 40. Specifically, the position of the conveyance belt 40 is detected by detecting the rib 40a. When the belt position detection sensor 40b detects the rib 40a one or more times, it is determined that the container 9 has been conveyed to the innermost reading area.

  Here, as shown in FIG. 26, the conveyance belt 40 has a contact amount between the container 9 supported between the pair of guide rollers 21 (guide members) and the front end surface of the rib 40a in the conveyance direction. It is preferable that they are arranged in a manner that gradually decreases.

  As described above, the contact amount between the container 9 supported by the guide roller 21 and the front end surface of the rib 40a formed on the transport belt 40 gradually decreases in the transport direction, that is, from the near side of the housing 20 to the back. If the transport belt 40 is arranged in this manner, as shown in FIG. 27A, the front end surface of the rib 40a and the container 9 come into contact with each other immediately after the start of transport, while FIGS. 27B to 27E show. Thus, after the container 9 reaches the reading area, the amount of contact between the rib 40a and the container 9 gradually decreases, and the rib 40a smoothly passes through the lower surface of the container 9. Therefore, an excessive load is not imposed on the motor 38 that drives the conveyor belt 40, and the life of the motor 38 can be extended.

  In addition, as shown in FIG. 28, in order that the conveyor belt 40 can bend downward, the teeth formed on the conveyor belt 40 and the teeth formed on the rollers 36, 37, and 39 do not jump out. The conveyor belt 40 may be wound around 36, 37, 39. 28 is partially provided with a belt guide 40c so as to reliably transport the container 9 immediately after the start of transportation.

  As described above, when the conveyor belt 40 is gently wound around the rollers 36, 37, and 39, as shown in FIG. 28 (a), the tip end surface of the rib 40a and the container 9 come into contact immediately after the start of the conveyance. 28 (b) to (e), after the container reaches the reading area, the conveying belt 40 is bent and the contact amount is reduced, and the rib 40a smoothly passes through the lower surface of the container 9. . Accordingly, the conveyor belt 40 can be bent to reduce the load without imposing an excessive load between the lower surface of the container supported between the pair of guide rollers 21 and the rib 40a formed on the conveyor belt 40. it can. As a result, the life of the motor 38 can be extended.

  The casing 20 to which the guide roller 21, the drive mechanism 22, the support mechanism 23, and the conveying means 35 are attached is supported by a cantilever mechanism 41 having a weight measuring means 41a as shown in FIG. When the container 9 is placed between the guide rollers 21, the weight can be measured through the weight measuring means 41a. The weight measuring unit 41a is, for example, a load cell, and measures the weight as a change in voltage with a strain gauge. The cantilever mechanism 41 is provided with protection means 42. The protection means 42 is used to support the load in place of the weight measurement means 41a when a container having a weight exceeding the upper limit set in the weight measurement means 41a, for example, a container that has left the beverage unloaded, is placed. Is. Specifically, a stopper is disposed on the lower surface of the free end of the cantilever mechanism 41 so that an overload is not applied to the weight measuring means 41a when a load exceeding the upper limit is applied.

  As shown in FIG. 3, a reading unit 5 (reading unit) that reads product information attached to the loaded container 9 is disposed obliquely above the container transport unit 4. The product information attached to the container 9 is product information such as a manufacturer code and a product item code indicated by a barcode. The reading unit 5 includes a barcode reader 43 and a motor 44 that rotates the barcode reader 43.

  The weight measuring unit 41a and the reading unit 5 are connected to an identification unit (not shown). The identification unit (not shown) identifies whether or not the charged container 9 has been set as a collection target in advance. Regarding the containers to be collected, the product information and the weight are registered in advance in association with each other. The identification unit (not shown) determines whether or not the product information read by the reading unit 5 and the weight measured by the weight measuring means 41a are registered in association with each other, and only when the product information is registered in advance. Handle as a container for collection.

  As shown in FIG. 7, a sorting unit 6 is disposed above the container transport unit 4. The distribution unit 6 distributes the container 9 placed between the pair of guide rollers 21 to the volume reduction processing unit 8 side when the container 9 is a collection target, and rotates the bail 45 and the bail 45. And a motor 46.

  The bail 45 is mounted on a frame 47 attached to stand on the front side of the housing 20 and a frame 48 attached to stand on the back side of the housing 20 around a substantially horizontal axis along the front-rear direction. Is attached to be rotatable. Specifically, a rotating shaft 49 is attached to the bail 45, and the rotating shaft 49 is supported by the frame bodies 47 and 48. A timing pulley 50 is fixed to the rotating shaft 49, and a motor 46 is attached to the frame 48. A timing pulley 51 is fixed to the drive shaft of the motor 46, and a timing belt 52 is wound between the timing pulley 50 and the timing pulley 51. Accordingly, when the motor 46 is driven, the bail 45 rotates as shown in FIG. 13, and the container 9 on the guide roller 21 can be distributed to the delivery unit 7 (volume reduction processing unit side).

  The distribution unit 6 further includes distribution operation prohibiting means 53. The distribution operation prohibiting means 53 prohibits the operation of the bail 45 when the insertion port 10 is opened, and more specifically, a hole 54 formed in the bail 45 and a plunger inserted into and extracted from the hole 54. 55. The plunger 55 is driven by a solenoid (not shown) attached to the frame 48 on the back side. The plunger 55 penetrates the hole 54 when no power is supplied, and the operation of the bail 45 is prohibited. The bail 45 is allowed to operate by being pulled out of the hole 54.

  As shown in FIG. 7, a delivery unit 7 is disposed on the left side of the container transport unit 4. As shown in FIGS. 14 and 15, the delivery unit 7 includes a base 56, a shooter 57, and a pusher 58. The base 56 is attached to the partition plate 1 </ b> A, and a shooter 57 is attached above the base 56. The shooter 57 receives the containers 9 distributed by the allocating unit 6, has a slit 57a (see FIG. 7) at the center, and is formed in such a manner that the width gradually increases upward.

  The pusher 58 is a mode in which the received container 9 is slid on the shooter 57, and is sent to the volume reduction processing unit 8. As shown in FIG. 16, the pusher 58 can be pulled out from the base 56 together with its guide 58a. is there. A drive mechanism 59 that causes the pusher 58 to travel as shown in FIG. As shown in FIG. 17, the drive mechanism 59 includes a motor 60 disposed on the front side of the machine room 1B, a timing pulley 61 fixed to the motor 60, a timing pulley 62 rotatably attached to the back side, The timing belt 63 is wound between the timing pulleys 61 and 62, and a leading portion 64 is fixed to the timing belt 63. For this reason, when the motor 60 is rotated, the leading portion 64 travels from the near side to the far side of the machine room 1B. The leading portion 64 and the pusher 58 are connected via a tension coil spring 65 and travel in such a manner that the pusher 58 follows the leading portion 64.

  The pusher 58 further has a tilting mechanism 66. The tilting mechanism 66 makes the pusher 58 tilt backward toward the volume reduction processing unit 8 when the container 9 is conveyed, and makes the pusher 58 upright when the container 9 reaches the volume reduction processing unit 8. As shown in FIGS. 18 and 19, the base portion 67, the tilt plate 68, the first link 69, and the second link 70 are provided. A tilting plate 68 is rotatably attached to the base portion 67, and the base portion 67 and the tilting plate 68 are connected by a first link 69 and a second link 70 to form a so-called four-bar link. Have

  The base 56 is provided with a stopper 71 (see FIG. 14) that shifts the tilting plate 68 to an upright state when the container 9 is received from the distribution unit 6. When the pusher 58 is in the standby position, the stopper 71 presses the portion where the first link 69 and the second link 70 of the tilting mechanism 66 intersect to shift the tilting plate 68 from the rearward tilted state to the upright state.

  Below the shooter 57, as shown in FIG. 14, a collar portion 72 inclined in the lower right direction is disposed. For this reason, the undried liquid leaking from the container during delivery flows through the slit 57a of the shooter 57 in the lower right direction by the collar 72, so that undried liquid flows into the drive mechanism 59, causing the drive mechanism 59 to become dirty. There is nothing to do. Moreover, the collar 72 is held by the guide 58a of the pusher 58 described above, and can be pulled out together with these. Therefore, the collar portion 72 can be easily cleaned.

  As shown in FIGS. 7 and 13, a buffer means 73 is provided between the container transport unit 4 and the delivery unit 7. The buffering means 73 suppresses the impact of the container 9 on the shooter 57 of the delivery part 7 when the container 9 is distributed from the container transport part 4 to the delivery part 7, and has a mounting plate 74 and a chain 75. Yes. The attachment plate 74 is attached to the base 56 of the delivery unit 7, and three chains 75 are suspended from the attachment plate 74. For this reason, the shock at the time of distribution is absorbed by the chain 75, and the impact of the container 9 on the shooter 57 is suppressed. As a result, the posture of the container 9 at the time of distribution can be stabilized.

  As shown in FIGS. 3 and 8, a volume reduction processing unit 8 is disposed in the back of the sending unit 7. As shown in FIGS. 20 to 22, the volume reduction processing unit 8 includes a pair of a first delivery roller 76 and a second delivery roller 77, a pair of a first volume reduction roller 78 and a second volume reduction roller 79. have. The first delivery roller 76 and the second delivery roller 77 are disposed to face each other, and the container 9 is supplied to the volume reduction rollers 78 and 79 through the pair of delivery rollers 76 and 77. The first delivery roller 76 and the second delivery roller 77 are made of a material that can be elastically deformed and has a large friction coefficient, such as rubber. These feed rollers 76, 77 are connected to ribs 76c, 77c that elastically deform the rotary shaft portions 76a, 77a and the outer peripheral portions 76b, 77b. Therefore, when the container is supplied between the first sending roller 76 and the second sending roller 77, the ribs 76c and 77c are elastically deformed, and the outer peripheral surface of the first sending roller 76 and the outer peripheral surface of the second sending roller 77 are deformed. The container 9 is sandwiched and sent between the first volume reduction roller 78 and the second volume reduction roller 79.

  As shown in FIG. 23, the first volume reduction roller 78 and the second volume reduction roller 79 are arranged to face each other. The first volume reduction roller 78 is provided with a row of first volume reduction teeth 78a along the axial direction. The second volume reduction roller 79 has a phase that is alternately positioned with the first volume reduction teeth 78a and has a phase that is set to be different in a range that intersects the phase of the rotation direction of the first volume reduction teeth 78a. Two rows of reduced-volume teeth 79a are arranged side by side.

  In addition, gaps 78 b and 79 b through which a specific portion of the container 9 passes are formed in a substantially central portion of the first volume reduction roller 78 and a substantially central portion of the second volume reduction roller 79. For example, when the container 9 is a plastic bottle, the specific portion of the container 9 is a hard portion that is formed to be thick, such as a drinking mouth portion or a bottom portion. Further, the gaps 78 b and 79 b are formed by missing the first reduction tooth 78 a at the substantially central portion of the first reduction roller 78 and the second reduction tooth 79 a at the substantially central portion of the second reduction roller 79. It is.

  The first volume reduction roller 78 has an outer shell 78c formed with first volume reduction teeth 78a that are in circumferential contact with the container 9, and a rotary shaft 80 to which the drive is transmitted. For example, an elastic body 81 such as rubber is interposed therebetween. Further, the relative rotation between the rotation of the outer shell 78c and the rotation of the rotary shaft 80 is regulated by a regulating means. The restricting means integrally rotates the outer shell 78c and the rotating shaft 80, and forms convex portions 78d and 80a on the outer shell 78c and the rotating shaft 80, respectively. Concave portions 81a and 81b are formed. In addition, it is preferable that the outer shell 78c of the first volume reduction roller 78 and the elastic body 81 are sequentially assembled to the rotary shaft 80 as a divided structure.

  Similarly to the first volume reduction roller 78, the second volume reduction roller 79 has an outer shell 79c formed with second volume reduction teeth 79a that are in circumferential contact with the container 9, and a rotary shaft 82 to which the drive is transmitted. An elastic body 83 is interposed between the outer shell 79 c and the rotating shaft 82. Further, the relative rotation between the rotation of the outer shell 79c and the rotation of the rotation shaft 82 is restricted by the restriction means. The restricting means is to rotate the outer shell 79c and the rotating shaft 82 in an integrated manner. The outer shell 79c and the rotating shaft 82 are respectively formed with convex portions 79d and 82a, and the elastic body 83 is fitted with these. Recesses 83a and 83b are formed. In addition, it is preferable that the outer shell 79c of the second volume reduction roller 79 and the elastic body 83 are sequentially assembled to the rotary shaft 82 as a divided structure.

  A collection shooter 84 for guiding the volume-reduced container 9 ′ to the collection box 1 D of the collection chamber 1 C is disposed further back in the volume reduction processing unit 8. The collection shooter 84 is formed so as to secure a space larger than the total length of the container 9 ′ separated from between the first volume reduction roller 78 and the second volume reduction roller 79.

  Next, the operation of the container recovery device will be described. In the container recovery device, the door 11 opens the insertion port 10 in the standby state, and the sorting operation prohibiting means 53 prohibits the operation of the bail 45. For this reason, even if a hand is inserted from the insertion port 10, the hand does not reach the volume reduction processing unit 8 due to being blocked by the bail 45.

  When the container 9 is inserted between the guide roller 21 and the guide roller 21 through the insertion port 10, signals are output in the order of the insertion port sensor and the container detection sensor, and the conveyance belt 40 is driven by the output from the container detection sensor. Begins. Note that the conveyance belt 40 may start running after the hand is removed from the insertion port 10 and the signal output of the insertion port sensor is stopped.

  The rib 40a comes into contact with the container 9 by the travel of the transport belt 40, and the container 9 in contact with the rib 40a is transported to the back side of the machine room 1B in a manner of sliding on the guide roller 21. When the container 9 is transported to the back side of the machine room 1B, the rib 40a bends and passes below the container 9. When a belt detection sensor (not shown) detects the rib 40a one or more times, it is determined that the container 9 has been transported to the far side of the machine room 1B.

  When it is determined that the container 9 has been transported to the back side of the machine room 1B, the motor 12 is rotated to move the door body 11 to the right in FIG. Subsequently, the reading unit 5 reads the product information while rotating the guide roller 21 counterclockwise in FIG. Since the product information is read while rotating the container 9, the product information attached to the container 9 can be read reliably.

  When product information cannot be read as in the case where product information is not attached to the container 9, the motor 12 is rotated to move the door body 11 to the left and the insertion port 10 is opened. At the same time, the conveyor belt 40 is caused to travel from the back of the machine room 1B to the near side, and is conveyed to the vicinity of the insertion port 10 so as to return the container 9.

  If the product information can be read, an identification unit (not shown) determines whether or not the product information is registered in advance. When the product information is registered in advance, the weight measuring unit 41a measures the weight of the container. On the other hand, when the product information is not registered in advance, the motor 12 is rotated to move the door body 11 to the left, the insertion port 10 is opened, and the transport belt 40 is moved from the back side of the machine room 1B. The container 9 is transported to the vicinity of the insertion port 10 by traveling forward.

  An identification unit (not shown) compares the measured weight of the container 9 with a value associated with product information in advance, and if the measured weight is included in the associated value, determines that the object is a collection target, and sets the associated value. If it is not included, it is judged not to be collected. If it is determined that the object is not to be collected, the motor 12 is rotated to move the door body 11 to the left, the input port is opened, and the transport belt 40 runs from the back side to the front side of the machine room 1B. Then, the container 9 is transported to the vicinity of the insertion port 10.

  When it is determined that it is a collection target, the distribution unit 6 is operated to distribute the containers 9 to the delivery unit 7 side (volume reduction processing unit 8 side). The containers 9 distributed to the delivery unit 7 side are de-energized by the buffer means 73 and then released to the shooter 57.

  At this time, the pusher 58 is in the standby position, and the tilting mechanism 66 is in an upright state. The sending unit 7 sends the container 9 on the shooter 57 to the volume reduction processing unit 8.

  The operation until the container 9 is delivered to the volume reduction processing unit 8 will be described more specifically. First, the leading portion 64 and the pusher 58 start traveling from the standby position toward the delivery position. When the travel is started, the pusher 58 shifts from the upright state to the rearward tilted state. When the container 9 comes into contact with the lower end of the pusher 58, the delivery of the container 9 is started. The interval between the leading portion 64 and the pusher 58 gradually increases, and the leading portion 64 first reaches the sending position. Subsequently, when the container 9 reaches the volume reduction processing unit 8, the pusher 58 is brought into an upright state, and the delivery of the container 9 is completed.

  The container sent to the volume reduction processing unit 8 is sent out between the first volume reduction roller 78 and the second volume reduction roller 79 by the first delivery roller 76 and the second delivery roller 77. More specifically, the first delivery roller 76 and the second delivery roller 77 sandwich the container 9 between the first delivery roller 76 and the second delivery roller 77 by deforming the ribs 76c and 77c. Then, it is fed between the first volume reduction roller 78 and the second volume reduction roller 79.

  The container 9 sent between the first volume reduction roller 78 and the second volume reduction roller 79 passes between the first volume reduction roller 78 and the second volume reduction roller 79 and performs volume reduction processing. More specifically, the first volume reduction teeth 78a of the first volume reduction roller 78 and the second volume reduction teeth 79a of the second volume reduction roller 79 gradually press the container, and the outer peripheral surface of the container 9 is entangled. In a manner, volume reduction treatment is performed.

  The container 9 ′ thus volume-reduced is guided by the collection shooter 84 and collected in the collection box 1D accommodated in the collection chamber 1C.

  In the container recovery apparatus according to the embodiment of the present invention described above, the outer peripheral surface of the guide roller 21 is formed with the low friction surface 21a and the high friction surface 21b along the axial direction on the outer peripheral surface of the guide roller 21. May be formed only by the high friction surface 21b.

  Further, the container 9 is transported by the transport belt 40 in which the ribs 40a are formed. However, as shown in FIG. 24, the transport belt 40 is convex with a high friction material without forming the ribs 40a. The part 140 may be attached, and the convex part 140 and the container 9 may be attached and conveyed. If an inclination is formed in the front end portion 140a and the rear end portion 140b of the convex portion 140, an impact generated when the container and the convex portion 140 abut can be buffered.

  Here, as shown in FIG. 30, the conveyor belt 40 is such that the upper surface of the convex portion 140 gradually separates from the lower surface of the container 9 supported between the pair of guide rollers 21 (guide members) in the conveying direction. It is preferable that they are arranged in a manner.

  In this way, the lower surface of the container 9 supported by the guide roller 21 and the upper surface of the convex 140 part formed on the conveyor belt 40 are gradually separated from each other in the conveyance direction, that is, from the front side of the housing 20 to the back side. If the transport belt 40 is disposed on the belt, as shown in FIG. 31 (a), the convex portion 140 and the container 9 are strongly engaged immediately after the start of transport, as shown in FIGS. 31 (b) to 31 (e). After the container 9 reaches the reading area, the engagement between the container 9 and the convex portion 140 gradually weakens, and the convex portion 140 smoothly passes through the lower surface of the container 9. Therefore, an excessive load is not imposed on the motor 38 that drives the conveyor belt 40, and the life of the motor 38 can be extended.

  In addition, as shown in FIG. 32, the rollers 36 are within a range in which the teeth formed on the conveyor belt 40 and the teeth formed on the rollers 36, 37, 39 do not skip so that the conveyor belt 40 can bend downward. , 37, 39 may be wound around the conveyor belt 40. 32 is partially provided with a belt guide 40c so as to reliably transport the container 9 immediately after the start of transportation.

  As described above, when the conveyor belt 40 is gently wound around the rollers 36, 37, and 39, as shown in FIG. 33A, the convex portion 140 and the container 9 are strongly engaged immediately after the start of the conveyance. 33 (b) to 33 (e), after the container reaches the reading area, the conveying belt 40 is bent, and the convex portion 140 passes through the lower surface of the container 9 smoothly. Therefore, the conveyor belt 40 is bent to reduce the load without imposing an excessive load between the lower surface of the container supported between the pair of guide rollers 21 and the convex portion 140 formed on the conveyor belt 40. Can do. As a result, the life of the motor 38 can be extended.

  Further, it is preferable that the convex portion 140 is provided shorter than the conveyance distance of the conveyance belt 40 and the conveyance belt 40 is stopped so as to be positioned on the back side of the conveyance surface when the container 9 is rotated. If the conveying belt 40 is stopped in this way, the bail and the container are not caught when the container 9 is distributed.

  In addition, the pusher 58 is brought into an upright state when the container 9 reaches the volume reduction processing unit 8, and the delivery of the container 9 is completed when the upright state of the pusher 58 is detected. 1 and a second interval corresponding to the completion of delivery of the container 9 are determined in advance, and the leading portion 64 and the pusher 58 are separated with a first interval by starting delivery of the container 9. After that, the delivery of the container may be completed on condition that the leading portion 64 and the pusher 58 are close to each other with a second interval.

  Further, an elastic body 81 is interposed between the outer shell 78 c of the first volume reduction roller 78 and the rotary shaft 80, and an elastic body 83 is interposed between the outer shell 79 c of the second volume reduction roller 79 and the rotary shaft 82. However, an elastic body may be interposed between the outer shell of at least one of the first volume reduction roller 78 and the second volume reduction roller 79 and the rotating shaft.

  Further, the phase in the rotational direction of the second volume reducing tooth 79a is set to be different from the phase in the rotational direction of the first volume reducing tooth 78a, but as shown in FIG. 25, the second volume reducing tooth 79a ′. The rotation direction phase may be set to coincide with the rotation direction phase of the first volume reducing tooth 78a ′. In addition, when it sets so that the phase of the rotation direction of 2nd volume reduction tooth 79a 'may correspond with the phase of the rotation direction of 1st volume reduction tooth 78a', 1st volume reduction tooth 78a 'and 2nd volume reduction are set. It is preferable that the teeth 79a ′ are arranged so as to have a predetermined gap in the inter-axis direction between the first volume reduction roller 78 and the second volume reduction roller 79. In this way, the first volume reduction roller 78a ′ and the second volume reduction tooth 79a ′ have a predetermined gap in the axial direction between the first volume reduction roller 78 and the second volume reduction roller 79. If the 78 and the second volume reduction roller 79 are provided, the occurrence of tearing of the container 9 when the volume of the container 9 is reduced can be suppressed.

  Further, as shown in FIG. 25, first rollers 85 are disposed at both ends of the first volume reduction roller 78, and second rollers 86 facing the first roller 85 at both ends of the second volume reduction roller 79. May be provided. The first roller 85 and the second roller 86 are preferably formed of an elastic body such as rubber and disposed so as to be in pressure contact with each other. In this way, when the first roller 85 is disposed at both ends of the first volume reduction roller 78 and the second roller 79 is disposed at both ends of the second volume reduction roller 79 so as to be in pressure contact with the first roller 85, For example, the end portion of the container 9 having resilience such as an empty plastic bottle is pressed and creased, so that when the volume is reduced, the shape is difficult to return, and the volume reduction rate can be improved.

  In addition, gaps 78b and 79b through which a specific portion of the container passes are formed at substantially the center of the first volume reduction roller 78 and the second volume reduction roller 79, but the gap need not necessarily be formed.

  According to the container recovery apparatus according to the above-described embodiment of the present invention, the container 9 that extends from the insertion port 3 to the site that reaches the distribution unit 6 is placed between the containers 9 that are input from the insertion port 3. And a transporting means 35 for transporting the container supported between the pair of guide rollers 21 to the distribution unit 6 in such a manner as to slide, the container 9 is placed in the distribution unit 6.
