  According to this configuration, the plurality of first cutting blades are transmitted with the rotational force of the motor and rotate around the eccentric shaft near the fixed blade.

  Therefore, the distance between the first cutting blade and the fixed blade can be increased when the first cutting blade and the fixed blade are separated from each other than when the first cutting blade is rotated about the central axis, and the distance between the two is approaching. Can be reduced.

  Therefore, solid incombustible material becomes easy to fit between the 1st cutting blade and the fixed blade rather than the case where the 1st cutting blade rotates centering on the central axis. Further, the force applied to the solid incombustible material when cutting the solid incombustible material can be increased without increasing the diameter of the first cutting blade.

  As a result, it is possible to reduce the size of the recovery device without reducing the cutting efficiency of the solid incombustible material.

  Each of the plurality of first cutting blades may have a recess into which the solid incombustible material is fitted.

A first recovery unit for recovering the cut incombustible material; It may be.

  According to this configuration, the magnet separates into solid incombustibles (for example, steel cans) attracted to the magnets and solid incombustibles (for example, aluminum cans, plastic bottles, glass bottles) that are not attracted to the magnets. Can easily separate solid incombustibles.

  For example, the second transport member may be either a mesh member or a porous member.

  According to this configuration, the liquid in the solid incombustible material mixed with the cut solid incombustible material flows to the lower part through the hole before being recovered in the first or second recovery unit. It is preferable for hygiene.

  Furthermore, a lower part of the second conveying member may include a waste liquid recovery unit that recovers the waste liquid mixed in the cut incombustible material.

  According to this configuration, since the liquid mixed in the cut incombustible material is collected by the waste liquid collection unit while passing through the second transport member, the waste liquid can be easily processed.

  Further, the cutting device further orthogonally crosses the solid incombustible material cut in a predetermined direction by the first cutting blade while rotating in a direction facing each other with a cutting direction by the first cutting blade. A pair of cutting rollers for further cutting in the direction, wherein the pair of cutting rollers includes a gap portion, and the gap portion is a position into which the tip of the solid incombustible material cut by the plurality of first cutting blades enters. May be provided.

  According to this configuration, the gap portion of the cutting roller that further cuts the incombustible material to be cut in a direction orthogonal to the cutting direction by the first cutting blade is provided at a position where the front end of the incombustible material cut by the first cutting blade enters. Therefore, the tip of the cutting incombustible material obtained by the first cutting blade smoothly reaches the second cutting portion without being caught by the cutting roller or other components in the casing. Therefore, the cutting by the second cutting unit is smooth.

  A pair of inlets for introducing the solid incombustible material is provided symmetrically with respect to a vertical center line that is a center line from the ground toward the upper surface of the housing, and the cutting device is provided in the housing. The first conveying member and the second conveying member may be provided in a pair symmetrically with respect to the vertical center line.

  According to this configuration, the pair of the cutting device, the first transport member, and the second transport member are provided symmetrically with respect to the vertical center line that is the center line from the ground toward the upper surface of the housing. Therefore, compared with the case where each component is not provided symmetrically, it is easier to arrange each component in the housing. As a result, cost reduction can be achieved.

  Further, at least the pair of cutting devices may be provided at a left end and a right end in the casing.

  According to this configuration, since the pair of cutting devices are provided at the left end and the right end of the casing, the weight is balanced to the left and right, so that the balance of the collection device can be improved.

The housing 2 is provided with two doors 20 on the front surface (surface opposite to the Y-axis direction). Each door 20 is provided with a handle 3. A person who collects the incombustible material hooks a finger on the handle 3 and opens the door 20 to the front.

  And in the front upper part of the housing | casing 2, opening 21A (1) and 21A (2) for throwing in a solid incombustible material are each a center line which goes to the upper surface of the housing | casing 2 from a ground as an inlet. They are provided symmetrically with respect to the vertical center line C. The opening 21A (1) is provided with a lid 21 (1) that opens and closes by rotating around the rotation shaft 21B (1). The opening 21A (2) is also provided with a lid 21 (2) that opens and closes by rotating about the rotation shaft 21B (2).

  The person who puts the solid incombustible material opens the lids 21 (1) and 21 (2) and puts the solid incombustible material into the openings 21A (1) and 21A (2). Then, the solid incombustible material is cut into chips in the housing 2 and then separated into those that are attracted to the magnet and those that are not, and each is recovered in the specified recovery boxes 40, 41, and 42, respectively.

  In the case 2, as shown in FIG. 2, the following components are provided symmetrically with respect to the vertical center line C as a reference. Hereinafter, components on the right side R of the vertical center line C will be described.

  The components on the left side L of the vertical center line C are the rotational directions of the cutting blade 27 (1) and the cutting blade 27 (2), the first conveying belt 25 (1) and the first conveying belt 26 (2). ), The rotation direction of the second conveyance belt 29 (1) and the second conveyance belt 29 (2), and the rotation direction of the transmission belt 80 are opposite to each other, and the rollers 26A to 26F, 30, And 31 are the same as those of the right side R except that the left side L and the right side R are opposite to each other.

  As described above, the opening 21 </ b> A (1) through which the solid incombustible material is introduced is provided as an input port for injecting the solid incombustible material in the upper front portion of the housing 2. And, other than solid incombustibles, for example, rain and dust do not enter the opening 21A (1), or a person who puts solid incombustibles does not accidentally put a hand into the opening 21A (1). A lid 21 (1) that closes the opening 21A (1) is provided. The lid 21 (1) exposes or closes the opening 21A (1) by rotating about the rotation shaft 21B (1). FIG. 2 shows a state in which the lid 21 (1) is opened and the opening 21A (1) is exposed.

  The lid 21 (1) is urged in the depth direction of the housing 2 by a pair of elastic members 21C such as a helical spring and is normally closed. When the lid 21 (1) is pulled forward by a person, the lid 21 (1) rotates about the rotation shaft 21B (1) against the urging force of the elastic member 21C. Thereby, it will be in the state where lid 21 (1) opened and solid incombustible material can be thrown into opening 21A (1).

  A detector 22 that detects whether the lid 21 (1) is closed corresponding to the lid 21 (1) and outputs a detection signal indicating the result to the control unit 100 (see FIG. 8). Has been placed. Any detector 22 may be used as long as it can detect whether or not the lid 21 (1) is closed. For example, a light receiving element and a light emitting element are provided, and the optical axis from the light emitting element is covered. When 21 (1) is blocked, an off signal is output to indicate that the lid 21 (1) is closed, and when the optical axis is not blocked by the lid 21 (1), an on signal is output. Therefore, the optical sensor may indicate that the lid 21 (1) is open. Alternatively, it may be a mechanical switch that is turned off in the process of closing the lid 21 (1) and turned on in the process of opening the lid 21 (1).

  From the opening 21A (1), a conveyance path 24 (1) leading to the cutting device 50 (1) is provided. As shown in FIG. 3, the conveyance path 24 (1) has a bent portion 240, and has an inclination of approximately 45 degrees in the depth direction from the opening 21 </ b> A (1) toward the bent portion 240. It is comprised so that it may become a perpendicular | vertical direction with respect to the ground toward the cutting apparatus 50 (1) from the part 240. FIG.

  Then, as shown in FIG. 2, the first conveying belt (first conveying member) that rotates in the horizontal direction with respect to the ground and toward the cutting device 50 (1) is directly below the bent portion 240. 25 (1) is provided.

  The first transport belt (first transport member) 25 (1) is stretched over the rollers 26A to 26F. At least one of the rollers 26 </ b> A to 26 </ b> F is given a rotational force that rotates the first transport belt 25 (1) in the clockwise direction. This 1st conveyance belt 25 (1) conveys the solid incombustible material thrown into opening 21A (1) horizontally to the cutting apparatus 50 (1).

  Thus, since the 1st conveyance belt 25 (1) conveys a solid incombustible material horizontally to the cutting apparatus 50 (1), the thickness of the collection | recovery apparatus 1 can be reduced. Further, since the opening 21A (1) and the cutting device 50 (1) are separated from each other, it is safe even if a person accidentally puts a hand into the opening 21A (1).

  In addition, a plate-like magnet 70 (1) such as a permanent magnet is provided at the bottom of the first transport belt 25 (1).

  The magnet 70 (1) has magnetized cutting incombustible material (solid incombustible material cut by the cutting device 50 (1)) conveyed by the second conveyance belt (second conveyance member) 29 (1). If the material is made of a material that can be used, the cut incombustible material (first cut incombustible material) is adsorbed.

  Further, immediately below the cutting device 50 (1), a second conveying member 29 (1) made of either a mesh member or a porous member is stretched between the roller 30 and the roller 31.

  Hereinafter, the rotation of the first conveyor belt 25 (2) and the second conveyor belt 29 (2) will be described with reference to FIG. FIG. 4 is a perspective view schematically showing the first conveyor belt 25 (2), the second conveyor belt 29 (2), and components around them.

  In the following description, the portion on the left side of the vertical center line C will be described, but the portion on the right side of the vertical center line C is also connected to the first conveyor belt 25 (2) and the second conveyor belt 29 (2). Since the relationship is the same, detailed illustration and description of the positional relationship between the first conveyor belt 25 (1) and the second conveyor belt 29 (1) are omitted.

  As shown in FIG. 4, a transmission gear 260E for transmitting the rotational force of the roller 26F to the second conveyor belt 29 (1) is attached to the front end of the roller 26E. The transmission gear 32 meshes with the transmission gear 260E. The transmission gear 32 is rotatably attached to the housing 2 or a dedicated attachment portion.

  A bridging portion 310 for bridging the transmission belt 80 is provided at the front end of the roller 31. The transmission belt 80 is bridged between the bridge 310 at the front end of the roller 31 and the transmission gear 32.

  According to such a configuration, when the first conveyor belt 25 (2) rotates counterclockwise, the transmission gear 32 rotates clockwise, so that the transmission belt 80 rotates clockwise. Then, since the bridging portion 310 also rotates clockwise, the roller 31 provided with the bridging portion 310 also rotates clockwise.

  As a result, the first conveyor belt 25 (2) rotates counterclockwise, while the second conveyor belt 29 (2) rotates clockwise.

  Therefore, the solid incombustible material 300 is transported in the direction of the first cutting blade 27 (2) by the first transport belt 25 (2), and is cut into chips there to become a cut product extending in the horizontal direction, which will be described later. By the cutting blade, a chip-shaped cut incombustible material 302 is obtained. The chip-shaped cut incombustible material 302 then falls onto the second conveyor belt 29 (2). The cut incombustible material 302 that has dropped onto the second conveyor belt 29 (2) is conveyed rightward by the rotation of the second conveyor belt 29 (2).

  Further, as shown in FIG. 2, in the housing 2, a waste liquid path 50 is provided in the vertical direction below the second transport belt 29 (1) on the roller 30 side of the second transport belt 29 (1). In the lower part of the waste liquid path 50, a waste liquid tank (waste liquid recovery part) 51 for recovering waste liquid such as the remaining juice collected in solid incombustibles is provided. In FIG. 2, the waste liquid is indicated by hatching in the waste liquid tank 51. Further, the second conveyor belt 29 (1) is not limited to the mesh member or the porous member, and may be provided with a hole for dropping the waste liquid to the lower part.

  As described above, since the second conveyor belt 29 (1) is composed of either a mesh member or a porous member, the waste liquid mixed in the incombustible material cut from the cutting device 50 (1) While being transported on the transport belt 29 (1), it falls to the waste liquid tank 51 (1) through the second transport belt 29 (1) and the waste liquid path 50. Accordingly, the amount of waste liquid in the steel can collection box 41 or the plastic bottle collection box 40 can be reduced, which is beneficial for hygiene.

  On the other hand, a plastic bottle collection box (second collection unit) 40 is provided below the second conveyance belt 29 (1) so as to be adjacent to the waste liquid tank 50. The aluminum can collection box 42 on the left side L of the housing 2 also constitutes a second collection unit.

  In addition, a steel can collection box (first collection unit) 41 is provided in the lower part of the first conveyance belt 25 (1) so that the opening is located directly below the left end of the magnet 70 (1). The steel can collection box 41 is arranged such that the vertical center line thereof overlaps the vertical center line C of the housing 2. Therefore, the steel can collection box 41 is symmetrical with respect to the vertical center line C.

  According to the above-described configuration, the solid incombustible material thrown into the opening 21A (1) is transported horizontally to the cutting device 50 (1) by the first transport belt 25 (1). The cutting incombustible material generated by the cutting device 50 (1) falls on the second conveyor belt 29 (1) and is conveyed leftward. The waste liquid mixed in the cut incombustible material falls into the waste liquid tank 51 (1) while being transported by the second transport belt 29 (1).

  Of the cut incombustible material conveyed by the second conveyor belt 29 (1), the second cut incombustible material (here, the plastic bottle cut material) that is not attracted by the magnet 70 is conveyed as it is, and is collected in a plastic bottle collection box. Fall to 40. On the other hand, the first cut incombustible material (here, the steel can cut material) attracted by the magnet 70 is attracted to the first conveying belt 25 (1) by the magnetic force, and the steel can collection box 41 is near the roller 26E where the magnetic force disappears. Fall into.

  Thus, since the 1st cutting incombustible material attracted to a magnet and the 2nd cutting incombustible material not attracted to a magnet can be distinguished by whether it is attracted by magnetic force, the cost concerning separation can be controlled. .

  In the collection device 1 according to the present embodiment, the above-described components are provided symmetrically with respect to the vertical center line C of the housing 2. Therefore, it is easy to arrange each component in the housing 2 as compared with the case where the respective components are not provided symmetrically. As a result, the recovery device 1 can be easily manufactured and the cost can be reduced.

  In the cutting device 50 (1), the first cutting blade 27 (1) rotates about the eccentric shaft 60 (1) to cut solid incombustibles. The cutting device 50 (1) rotates around the first cutting blade 27 (1) and the central shaft 61 (1) so that the solid incombustible material is orthogonal to the cutting direction of the first cutting blade 27 (1).

  As described above, the first cutting blade 27 (2) rotates about the eccentric shaft 60 (2) near the fixed blade 71 (2), so the first cutting blade 27 (2) is centered on the central axis 65. When the first cutting blade 27 (2) and the fixed blade 71 are separated from each other, the distance between them can be increased, and when both are approaching, the distance can be decreased.

  Therefore, the solid incombustible material 300 fits between the first cutting blade 27 (2) and the fixed blade 71 (2), compared to the case where the first cutting blade 27 (2) rotates about the central axis 65. It becomes easy. Further, the force applied to the solid incombustible material 300 when the solid incombustible material 300 is cut can be increased without increasing the diameter of the first cutting blade 27 (2).

  As a result, the collection device 1 can be downsized without reducing the cutting efficiency of the solid incombustible material 300.

  Furthermore, since the shape of the first cutting blade 27 (2) is substantially cam-shaped, the first cutting blade 27 (2) is located inside the housing 2 as compared with the case where the first cutting blade 27 (2) is circular. Since the area occupied by can be reduced, the collection apparatus 1 can be further downsized.

  Further, as described above, the solid incombustible material 300 is inserted into the first cutting blade 27 (2) and the fixed blade 71 (2) in a state where the solid incombustible material 300 is fitted in the recess 270 of the first cutting blade 27 (2). Therefore, the solid incombustible material 300 can be cut in a state in which the solid incombustible material 300 is firmly sandwiched between the first cutting blade 27 (2) and the fixed blade 71. Further, since the recess 270 exists, the solid incombustible material 300 having a larger volume can be cut without changing the positional relationship between the first cutting blade 27 (2) and the fixed blade 71. As a result, the collection device 1 can be further downsized.

<Functional configuration of collection device 1>
FIG. 9 is a diagram illustrating an example of functional blocks of the collection apparatus 1.

  The collection apparatus 1 includes a control unit 100, a timer 101, a motor 23 (1) as a first cutting motor, a motor 23 (2) as a second cutting motor, a first transport motor 102 (1), A second transport motor 102 (2), a detector 22 (1) as a first detector, and a detector 22 (2) as a second detector are provided.

  The control unit 100 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a RAM (Read Only Memory), and the like, and is realized by the CPU executing a predetermined control program. The control unit 100 controls the following units.

  The timer 101 is used in the operation of the collection device 1 (described later) and measures time. The first cutting motor 23 (1) includes a motor 23 (1) for driving the cutting device 50 (1). The second cutting motor 23 (2) includes a motor 23 (2) for driving the cutting device 50 (2).

  The first transport motor 102 (1) is a motor for driving the transport system on the right side R of the housing 2, and specifically, the first transport belt 25 (1) and the second transport belt 29 ( A rotational force is given to 1).

  The second conveyance motor 102 (2) is a motor for driving the conveyance system on the left side L of the housing 2, and specifically, the first conveyance belt 25 (2) and the second conveyance belt 29 ( Apply rotational force to 2).

  The first cutting motor 23 (1) and the first transport motor 102 (1) constitute a first cutting system on the right side R of the housing 2, while the second cutting motor 23 (2) and the second transport motor. 102 (2) constitutes the second cutting system on the left side L of the housing 2.

  The first detector 22 (1) detects whether or not the right lid 21 (1) of the housing 2 is closed. The second detector 22 (2) detects whether or not the left lid 21 (2) of the housing 2 is closed.

<Operation of Collection Device 1>
Next, operation | movement of the collection | recovery apparatus 1 is demonstrated using FIG.2, FIG.9 and FIG.10.

  FIG. 10 is a flowchart showing an example of the operation of the collection apparatus 1. In the following description, the first detector 22 (1) and the second detector (2) are constituted by optical sensors, and an off signal indicates that the lids 21 (1) and 21 (2) are closed. On the other hand, the ON signal indicates that the lids 21 (1) and 21 (2) are open.

  The control unit 100 is in a standby state until one of the first detector 22 (1) and the second detector 22 (2) does not detect that the lids 21 (1) and 21 (2) are closed. To maintain. In the following description, it is assumed that the lid 21 (1) on the right side of the housing 2 is opened.

  When the lid 21 (1) can no longer be closed (YES in step S1), the controller 100 then puts solid incombustible material into the opening 21A (1). When the controller 100 detects that the lid 21 is closed (YES in step S2), the controller 100 starts measuring time by the timer 101 (step S3). It should be noted that which of the first cutting system and the second cutting system starts the operation to be described later is which lid 21 (1), 21 (2) has been opened first from the viewpoint of the allowable current. It depends on whether or not.

  When a predetermined first set time (for example, 5 to 10 seconds) has elapsed since the time measurement by the timer 102 has started (YES in step S4), the first transport motor 102 (1) and the first cutting motor 23 (1) is driven (steps S5 and S6).

  Thereby, the solid incombustible material thrown into the opening 21A is transported to the cutting device 50 (1) by the first transport belt 25 (1), and is cut into chips by the cutting device 50 (1). Become. The cut incombustible material falls onto the second transport belt 29 (1) and is transported toward the first transport belt 25 (1).

  Of the cut incombustibles, those that are attracted to the magnet 70 (1) (for example, a steel can) remain attached to the first conveyor belt 25 (1) under the attraction force of the magnet 70 (1). Further, it is transported and dropped to the steel can collection box 41 when the attraction force disappears at the left end of the magnet 70 (1).

  On the other hand, of the cut incombustibles, those that are not attracted to the magnet 70 (1) (for example, aluminum cans) do not receive the attractive force in the direction of the first conveyor belt 25 (1), so the second conveyor belt 29 (1 ) Drops to the plastic bottle collection box 41 when it reaches the left end.

  Thereby, the cutting incombustible material having the property of being attracted to the magnet 70 (1) and the cutting incombustible material having the property of not being attracted to the magnet 70 (1) are separated and collected.

  By the way, when the lid 21 has been opened during the cutting of the solid incombustible material (YES in step 7), as a safety measure, the time measurement by the timer is ended (step S8), and the first cutting motor 23 (1) and The driving of the first transport motor 102 (1) is stopped (steps S9 and S10).

  On the other hand, if the lid 21 is not opened during cutting (NO in step S7), a predetermined second set time (for example, 15 to 20 seconds) from the time when the timer 102 starts measuring in step S3. When the time has elapsed (YES in step S11), the timing by the timer 102 is terminated (step S12), and the driving of the first cutting motor 23 (1) and the first transport motor 102 (1) is stopped (steps S13 and S14). ). Thereafter, the control unit 100 returns to the standby state.

  In the above-described embodiment, the control unit 100 detects the opening / closing of the lid 21 by using optical sensors as the first detector 22 (1) and the second detector 22 (2). A mechanical switch that is turned off in the process of closing the lid 21 and turned on in the process of opening the lid may be used.

  Further, from the viewpoint of energy saving, when the person for putting solid incombustible material opens the lid 21, the mechanical switch is turned on to turn on the power of the recovery device 1, and a series of cutting processes and When the transport process is completed, the power of the collection device 1 may be turned off.

  According to the said structure, when separating and collect | recovering as a solid incombustible material in each of an aluminum can, a steel can, and a PET bottle, it is useful.

<Modification>
FIG. 11 is a view showing another example of the recovery apparatus according to the embodiment of the present invention.

  The recovery device 1A includes an opening 21A (3) for inserting a glass bottle, a glass bottle conveyance path 24 (3), and a glass bottle collection box 43 for collecting the glass bottle as it is, on the right side R of the housing 2. Is different from the recovery device 1 in that the magnet 70 (1) is not provided on the first conveyor belt 25 (1).

  According to this configuration, when the opening 21 </ b> A (3) is opened and a glass bottle is inserted, the glass bottle is conveyed through the conveyance path 24 (3) as it is and reaches the glass bottle collection box 43.

  On the other hand, if the lid 21 (1) is opened, a plastic bottle is put into the opening 21A (1), and the lid 21 (1) is closed, the lid 21 (1) is conveyed rightward by the first conveying belt 25 (1), and the cutting device 50 It is cut into chips by (1) and falls onto the second conveyor belt 29 (1). Then, the chip-shaped cut material is conveyed by the second conveyance belt 29 (1), and when it reaches the left end of the second conveyance belt 29 (1), it is dropped into the plastic bottle collection box 40 and collected.

  The reason why the glass bottle is not cut is that the glass bottle is less sold and less frequently collected than aluminum cans, steel cans, and PET bottles. Or, if a glass bottle is cut, the cut is dangerous for the human body.

  According to this structure, it is useful when separating and collecting each of aluminum cans, steel cans, glass bottles, and PET bottles as solid incombustibles.

  The present invention can be applied to a recovery device that is provided near a convenience store, a vending machine, or the like and collects solid incombustibles such as aluminum cans.
