Description

  The present invention relates to a sorting conveyor including a plurality of conveyance units that move along a conveyance route formed in a loop shape, and in particular, includes a cross sorter in which a conveyance surface that travels in a direction orthogonal to the movement direction is arranged in each conveyance unit. It relates to sorting conveyors.

  Among sorting conveyors that connect a large number of transport units that move along a transport route formed in a loop, a cross sorter conveyor having a transport surface such as an endless belt conveyor or a roller conveyor is provided above each transport unit. It is generally known to move a conveyed product in a direction orthogonal to the moving direction of the transfer unit by a cross sorter conveyor. As a method for driving a conveyor for a cross sorter provided in each transport unit, a method of driving by a motor driven by a transport unit side power feeding using a current collector that moves in contact with a rail-shaped power feeding unit provided on the ground side, a generator, Examples include a method in which a power supply device including a storage battery is provided in the transport unit and driven by a motor driven by power supply generated by rotation of a generator rotor transmitted from a rotating mechanism that contacts a ground rail or the like. In addition to this, a wheel provided in the transport unit is rotated while contacting a ground-side guide rail provided so as to protrude and retract at an appropriate position on the transport route, and the rotational force of the rotating wheel is transmitted. Thus, a technique for driving the transport surface of the cross sorter conveyor according to a predetermined sorting unit has been devised.

  However, in the case where the motor is driven by supplying power by collecting current that is slid to the ground-side power feeding unit, or the motor is driven by power feeding by rotating the generator by a rotating mechanism that contacts the ground-side rail, each transport unit Since the drive motor for the conveyor for the cross sorter is provided, the structure of the transport unit is complicated or the number of parts constituting the conveyor is increased, so that the maintenance efficiency and the initial cost are deteriorated.

  On the other hand, the wheel provided in the transport unit is rotated while being in contact with the ground-side guide rail provided so as to protrude and retreat at an appropriate position on the transport route, and the cross sorter conveyor is driven by transmitting the rotational force of the wheel. In this case, for example, when a wheel made of a compound such as urethane is used, when the wheel first contacts the ground side guide rail that protrudes when sorting, there is a risk that the wheel will receive an impact and be damaged. In addition, if the contact force between the wheel and the guide rail is increased to ensure driving reliability, the wheel will be damaged or wear will be accelerated even if it does not reach it, and if the contact force is weak, the wheel will rotate well. Therefore, the rotational force of the wheel cannot be properly transmitted to the cross sorter conveyor.

  The present invention provides a sorting conveyor equipped with a cross sorter that can be driven reliably and with a simple structure as a mechanism without mounting a drive motor that requires electric power on each transport unit as a drive mechanism for a cross sorter conveyor.

A plurality of transport units connected in a loop, and when the transport unit moves to a preset position, the transport surface can travel in a direction orthogonal to the moving direction of the transport unit, A cross sorter conveyor held by a holding frame, a plurality of iron cores arranged on the ground side corresponding to the preset position on the transport route, and disposed along the transport route, and the plurality of cores It is composed of an electric wire having the same number of windings to the plurality of iron cores, the winding direction being reversed in a plan view with respect to adjacent iron cores among the iron cores, and at the time of power feeding An electromagnet unit that generates magnetic poles with alternating polarities in the direction along the feeding route and a plurality of permanent magnets with polarities alternately arranged in the rotational direction are arranged on the outer peripheral surface and arranged on the ground side. Depending on the attractive force and repulsive force of the magnetic pole generated in the electromagnet unit that is horizontally supported by the transport unit so as to approach through a predetermined gap even when the position of the electromagnet unit is reached. A non-contact rotating magnetizing rotor; and a transmission mechanism for transmitting the rotation of the magnetizing rotor to the cross sorter conveyor to travel the transport surface of the cross sorter conveyor. When traveling the transport surface to the right with respect to the direction of movement of the transport route with respect to the preset position, the electromagnet unit is moved to the magnetized low position. The electromagnet is disposed on the ground side so as to be located below the conveyor, and when the conveyor surface of the cross sorter conveyor is caused to travel to the left with respect to the direction of movement of the conveyor route with respect to the preset position. The unit is provided to be disposed on the ground side so as to be positioned above the magnetized rotor.

  The transmission mechanism includes a gear train that transmits the rotational force of the magnetized rotor to the upstream end or the downstream end in the moving direction of the transport route of each cross sorter conveyor, and the rotation of the gear train end is transported to the cross sorter conveyor. It is preferably composed of an endless timing belt or an endless chain that transmits to a surface level, and a toothed pulley or sprocket that drives a member that forms the conveyor transport surface for the cross sorter.

  The transport route includes a center rail on the ground side that guides a moving direction of the transport unit moving along the transport route, and the transport unit has a vertical portion of the center rail at a link connecting portion. It is preferable to have a guide wheel that rotates by being brought into contact with the cutting surface.

  According to the present invention, the permanent magnets are provided on the outer peripheral surface with their polarities alternately arranged in the rotation direction, and are supported on the transport unit so as to approach through the predetermined gap even when reaching the position of the electromagnet unit. The cross sorter can be easily and reliably configured with the magnetized rotor and the electromagnet unit which is arranged on the ground side and generates the magnetic poles alternately only when the polarity is alternately arranged in the direction along the transport route. The conveyor can be driven. In addition, since the magnetizing rotor is arranged so as to approach through a predetermined gap even when it reaches the position of the electromagnet unit, the magnetizing rotor and the electromagnet unit are not subjected to impact due to a collision at the time of sorting, The rotation of the magnetized rotor is accelerated while allowing slipping, and then the rotation of the magnetized rotor is given a predetermined number of rotations in synchronization with the magnetic pole pitch of the electromagnet unit and the magnetic pole pitch of the magnetized rotor.

  In addition, since the magnetized rotor is rotated using the magnetic pole generated by the electromagnet unit, the position of the magnetized rotor with respect to the electromagnet unit can be reduced without performing the positional accuracy of the magnetized rotor with high accuracy. Since the arrangement pitch and the magnetic pole pitch of the different magnetic pole band of the electromagnet unit are synchronized immediately after the magnetizing rotor starts rotating, the cross sorter conveyor can be driven reliably.

  FIG. 1 is a plan view of a sorting conveyor equipped with the cross sorter of the present invention. The sorting conveyor 10 of the present invention moves (runs) along a loop-shaped transport route in a state where a large number of transport units 11 are connected to each other. The sorting conveyor 10 is driven by a drive unit (not shown). As a method of this drive unit, a well-known friction drive method can be cited. Specifically, in this method, a large number of lateral surfaces of a link 22 (to be described later) extending along the transport route direction at the lower part of the transport unit 11 are provided at the tips of arms fixed to a support cylinder with a built-in torsion spring. When the friction roller moves from the back side of the friction belt in the direction of pressure contact with the link, it is clamped by a pair of forward friction belts and rotates a pair of endless friction belts to send out the link 22 of the transport unit 11 as a whole. Is to drive.

  When the sorting conveyor 10 is driven, each transport unit 11 moves in the direction A in the figure. When each transport unit 11 moves, a transported object that is carried and transported by a transport conveyor 15 disposed on the upstream side is placed on each transport unit 11. Even after the transported object is transferred and placed, the transport unit 11 moves in the direction A in the drawing, and moves to the position of the target sorting conveyor 16 or sorting chute 17 disposed on the downstream side. The provided cross sorter conveyor is driven. By this drive, the conveyed product placed on the conveyance unit 11 moves toward the sorting conveyor 16 and the sorting chute 17 (B direction in the figure), and the conveyed item is sorted.

  Hereinafter, the endless belt conveyor 20 will be described as an example of the cross sorter conveyor. Further, a position where the cross sorter conveyor is driven and paid out to the sorting conveyor 16 or the sorting chute 17 will be referred to as a sorting position.

  As shown in FIGS. 2 to 4, the transport unit 11 includes a holding frame 21 including an endless belt conveyor 20 and a link 22. The holding frame 21 is composed of a plurality of members. Pulleys 31 and 32 are rotatably attached to both end portions of the side frames 25 and 26 constituting the holding frame 21 via bearings 30. The pulleys 31 and 32 are arranged so that the axial direction thereof is the same as the longitudinal direction of the link 22. Of these pulleys 31 and 32, the rotation shaft 31a of the pulley 31 protrudes from the side frame 26, and a toothed pulley 73 constituting a transmission mechanism 62 described later is fixed to the protruding portion. Thereby, the pulley 31 becomes a drive pulley and the pulley 32 becomes a driven pulley. Hereinafter, the pulley 31 will be referred to as a driving pulley 31 and the pulley 32 will be referred to as a driven pulley 32.

  V-grooves 34 are provided at both ends of the drive pulley 31, and V-grooves 35 are provided at both ends of the driven pulley 32. Protrusions (not shown) are provided in the vicinity of the left and right ends of the back surface of the endless belt 33 wound around the drive pulley 31 and the driven pulley 32. When the endless belt 33 is wound around the drive pulley 31 or the driven pulley 32, The protrusions provided on the endless belt 33 are engaged with the V grooves 34 and 35 described above. Thereby, the meandering of the traveling endless belt 33 is prevented when the endless belt conveyor 20 is driven. The V-groove described above can also be provided at one end of the drive pulley 31 and the driven pulley 32. By providing a protrusion on the back surface of the endless belt 33, a similar V groove 36 is provided in the slide bed 28 of the holding frame 22.

  Members 41 and 42 having a U-shaped cross section are fixed to the lower portions of the side frames 25 and 26, respectively. The holding frame 21 and the link 22 are fixed through these members 41 and 42. Among these members 41, 42, brackets 43, 44 are attached to both ends of the member 42 attached to the side frame 26 of the transport unit 11 and extend rearward in the movement direction on the transport route of the transport unit 11. Under the brackets 43 and 44, a pair of traveling wheels 45 and 46 are pivotally supported by shafts extending in the vertical direction, and are attached to be rotatable in the horizontal direction.

  The traveling wheel pair 45 includes two traveling wheels 47 and 48 having a predetermined gap, and a holder 49 to which the traveling wheels 47 and 48 are rotatably attached. A gap is formed between the traveling wheels 47 and 48. A ground-side guide rail 57 having horizontal contact surfaces formed on both sides thereof along the conveyance route enters the gap formed between the traveling wheels 47 and 48. The traveling wheel pair 46 also has the same configuration as the traveling wheel pair 45, that is, two traveling wheels 51 and 52, and a holder 53 to which these traveling wheels are rotatably attached. A gap is also formed between the traveling wheels 51 and 52, and the ground side guide rail 58 having a horizontal contact surface formed along the transport route enters.

  Thus, when the sorting conveyor 10 is driven, the traveling wheel 47 of the traveling wheel pair 45 is on the upper surface of the horizontal contact surface of the ground side guide rail 57, and the traveling wheel 48 is the lower surface of the horizontal contact surface of the ground side guide rail 57. Rotate while being in contact with each other. The traveling wheel 51 of the traveling wheel pair 46 rotates while being in contact with the upper surface of the horizontal contact surface of the ground side guide rail 58 and the traveling wheel 52 is in contact with the lower surface of the horizontal contact surface of the ground side guide rail 58. . Reference numeral 59 denotes a gap plate provided at the front and rear ends of the holding frame 21 of each transport unit 11.

  In this way, the traveling wheel pair 45 is pivotally supported by the shaft extending in the vertical direction with respect to the bracket 43 and is rotatable in the horizontal direction, and the traveling wheel pair 46 is pivotally supported by the shaft extending in the vertical direction with respect to the bracket 44 and horizontally. By mounting so as to be rotatable in the direction, the traveling wheel pairs 45 and 46 are inclined at an angle according to the curve in the process of moving the curve provided in the transport route. For this reason, the operation | movement of the conveyance unit 11 when moving the curve provided in a conveyance route can be made smooth. In addition, since the rotation center of each conveyance unit is located at the center (focus point) of the curve in the curve portion of the conveyance route, it is possible to suppress noise generated when moving within the curve.

  The driving of the endless belt conveyor 12 described above is executed by the electromagnet unit 60, the magnetizing rotor 61, and the transmission mechanism 62 shown in FIG. The electromagnet unit 60 is provided on the ground side of the transport route. For example, when considering a sorting position, it is necessary to surely pay out a specific transported item to a sorting chute or a sorting conveyor at this sorting position. For this reason, the position where the electromagnet unit 60 is arranged is determined so that the endless belt conveyor 12 is driven before the transport unit 11 reaches the sorting position.

  As shown in FIGS. 6A and 6B, the electromagnet unit 60 is an electric wire wound around each of a base 65 having a plurality of iron cores 65a arranged in a straight line and a plurality of iron cores 65a. A winding 66 and a cover 67 are included. The winding 66 is wound around the iron core 65a a predetermined number of times. The number of turns of the winding 66 for each of the iron cores 65a is the same. Moreover, the winding direction of the coil | winding 66 wound around each of the adjacent iron core 65a becomes a reverse direction. That is, when the winding 66 is wound clockwise around a certain iron core 65a, the winding 66 may be wound counterclockwise around the iron core 65a adjacent to the iron core 65a. The winding 66 wound around the iron core 65a may be a winding provided for each iron core, or a single winding may be wound around each iron core. As a result, when power is supplied to the electromagnet unit 60, the magnetic poles generated in the windings wound around the iron cores 65a are different between the adjacent iron cores 65a. The presence or absence of power supply to the electromagnet unit 60 is controlled by a control unit (not shown). In addition, the strength of the magnetic pole in the electromagnet unit 60 is set as appropriate, and FIG. 6 shows an example thereof. Therefore, the number of iron cores around which the winding is wound, the number of turns of the winding, and the like are set as appropriate.

  The magnetized rotor 61 has a plurality of permanent magnets (12 in FIG. 7) on its outer peripheral surface so that adjacent polarities are different, that is, the polarities generated on the outer peripheral surface of the rotor are N poles, S poles, It arrange | positions so that it may become N pole, S pole .... In FIG. 7, the polarity of the outer peripheral surface of the magnetized rotor 61 is shown in the permanent magnet in order to prevent the drawing from being complicated. This magnetized rotor 61 has a predetermined width between the upper surface of the electromagnet unit 60 and the lowest point of the magnetized rotor 61 so that it does not collide with the electromagnet unit 60 arranged on the transport route when the transport unit 11 moves. It is pivotally supported by an axis that is horizontally downward from the holding frame 21 and orthogonal to the moving direction of the transport route so that an H gap is formed. The magnetized rotor 61 is fixed to a rotating shaft 75a of a bevel gear 75 described later.

  FIG. 7 shows the relationship between the magnetized rotor 61 and the electromagnet unit 60 when the magnetized rotor 61 moves in the A direction. For example, when power is supplied to the electromagnet unit 60, the magnetic poles are alternately formed in the electromagnet unit 60. As described above, a plurality of permanent magnets are arranged on the outer peripheral surface of the magnetized rotor 61 so that the magnetic poles are alternated, so that they are affected by the magnetic poles generated by the electromagnet unit 60. For example, when the magnetized rotor 61 moves above the electromagnet unit 60, for example, if the opposing magnetic poles are S poles or N poles, they are repelled, and the magnetized rotor 61 rotates in the C direction. Thereafter, when the opposing magnetic poles of the magnetized rotor 61 and the magnetic pole of the ground-side electromagnet unit 60 are attracted to the S pole and the N pole, the iron core arrangement pitch of the electromagnet unit 60 and the different pole arrangement pitch of the magnetized rotor 61 are obtained. In synchronization, the magnetized rotor 61 rotates according to the iron core arrangement pitch of the electromagnet unit 60. The iron core arrangement pitch of the electromagnet unit 60 and the different pole arrangement pitch of the magnetized rotor 61 are strongly synchronized by the repulsive force between the different poles and the adjacent different pole. On the other hand, when no power is supplied to the electromagnet unit 60, no magnetic pole is generated in the electromagnet unit 60, so the magnetized rotor 61 does not rotate.

  Returning to FIG. 5, the transmission mechanism 62 includes a gear box 71 having a gear train composed of a plurality of gears, toothed pulleys 72 and 73, and a timing belt 74. The gear box 71 is attached to the lower surface of the lower frame 27 that connects the side frames 42 and 43 below the transport unit 11 and to the rear end side in the moving direction of the transport route. Examples of the gear train provided in the gear box 71 include two bevel gears 75 and 76. Of these bevel gears 75, 76, the magnetized rotor 61 is fixed to the rotating shaft 75 a of the bevel gear 75, and the toothed pulley 72 is fixed to the rotating shaft 76 a of the bevel gear 76. The bevel gears 75 and 76 are engaged with each other, so that the rotation direction when the magnetized rotor 61 rotates can be converted and the rotation can be transmitted to the toothed pulley 72 in the subsequent stage. Note that the bevel gear 75 also rotates in the C direction by the rotation of the magnetized rotor 61 in the C direction. The bevel gear 76 meshing with the bevel gear 75 converts the rotation of the bevel gear 75 in the C direction into the rotation in the D direction.

  As described above, the toothed pulley 72 is fixed to the rotating shaft 76 a of the bevel gear 76, and the toothed pulley 73 is fixed to the rotating shaft 31 a of the driving pulley 31. A timing belt 74 is wound around these toothed pulleys. As described above, when the magnetized rotor 61 is rotated in the C direction, the bevel gear 76 that meshes with the bevel gear 75 rotates in the D direction. Since the toothed pulley 72 is fixed to the rotating shaft 76 a of the bevel gear 76, the toothed pulley 72 rotates in the D direction, like the bevel gear 76. The rotation of the toothed pulley 72 pushes the wound timing belt 74 in the E direction, and the timing belt 74 travels. Thereby, the toothed pulley 73 rotates in the F direction. Since the pulley 73 is fixed to the rotation shaft 31a of the drive pulley 31, the drive pulley 31 rotates in the F direction in accordance with the rotation of the toothed pulley 73. If the conveyed product is placed on the endless belt conveyor 12, the endless belt of the endless belt conveyor 12 travels in the B direction by the rotation of the drive pulley 31.

  In the present embodiment, the gear train incorporated in the gear box 71 is composed of the two bevel gears 75 and 76. However, if the configuration is such that the rotation of the magnetized rotor 61 can be transmitted to the endless belt conveyor 12. It is not necessary to be limited to. The configuration of the transmission mechanism 62 is not necessarily limited to the above-described configuration, and may be a combination of an endless chain and a sprocket instead of the combination of the timing belt 74 and the toothed pulleys 72 and 73. It may be set appropriately in consideration of the configuration of the holding frame 21, the configuration of the cross sorter conveyor, or the configuration of the transport route.

  The link 22 is composed of a rectangular tube beam so as to withstand torsion caused by an unbalanced load when a conveyance object is placed on the conveyance unit 11. Adjacent transport units 11 are connected to each other using a connecting unit 81. The connecting unit 81 is attached to the end of the link 22.

  FIG. 8 is a top view of the connecting unit, and FIG. 9 is a side view of the connecting unit. The connection unit 81 includes a connection protrusion 82 provided on the rear end side in the movement direction of the transport route of the link 22 of the upstream transport unit 11 and the transport of the link 22 of the downstream transport unit 11 among the adjacent transport units 11. It comprises a connection receiving part 83 and a connection pin 84 provided on the front end side of the route in the moving direction. The connection protrusion 82 is attached to the front end portion in the movement direction of the conveyance route of the link 22 of the conveyance unit 11 on the rear side in the movement direction of the conveyance route among the adjacent conveyance units 11. The connection receiving portion 83 is attached to the rear end portion in the movement direction of the conveyance route of the link 22 of the conveyance unit 11 ahead of the conveyance route in the adjacent conveyance unit 11. In addition, since the connection protrusion 82 should just be provided in any one of the links 22 of the adjacent conveyance unit 11, and the connection receiving part 83 was provided in the other, the arrangement | positioning relationship between these connection protrusions 82 and the connection receiving part 83 is It is not necessary to be limited to the above.

  A take-up spacer 85 is provided between the link 22 and the connection protrusion 82 or between the link 22 and the connection receiving portion 83. The take-up spacer 85 absorbs the extension of the link 5 by being removed when the link 22 is extended.

  The connecting projection 82 is provided with a spherical sliding bearing (not shown). By providing this spherical sliding bearing, it is possible to realize stable movement of the transport unit 11 without being affected by the adjacent transport units 11 being bent in the left-right and vertical directions. In addition, noise such as running noise generated in a normal connecting unit is suppressed. The connection receiving part 83 is composed of two connection pieces 83a and 83b with a predetermined gap in the vertical direction. Here, the predetermined width is a width that exceeds at least the thickness of the connecting protrusion 82.

  The connection pin 84 inserts the connection protrusion 82 into the gap between the two connection pieces 83a and 83b provided in the connection receiving portion 83. For example, an opening provided in the connection pieces 83a and 83b and a spherical slip of the connection protrusion 82 are provided. It is suspended while being inserted into the bearing. As a result, the connection projection 82 and the connection receiving portion 83 are rotatable around the connection pin 84.

  A guide wheel (horizontal guide wheel) 86 that is rotatable about the connection pin 84 is attached to the lower end portion of the connection pin 84. The horizontal guide wheel 86 is held in a state of being inserted into a gap between the center rails 87 and 88 provided on the conveyance route.

  By providing the sorting conveyor having such a configuration, if only the presence / absence of power supply to the electromagnet unit 60 is controlled, the presence / absence of rotation of the magnetized rotor 61 can be controlled. In addition, by using a method in which the magnetized rotor 61 is rotated by magnetic poles generated by the electromagnet unit 60, a method in which a wheel formed of a synthetic resin such as urethane on its outer peripheral surface is in contact with the guide rail is rotated. The wheel does not come into contact with the guide rail, or the wheel does not come into contact with the guide rail. An endless belt conveyor can be driven. Further, since only the electromagnet unit 60 and the magnetizing rotor 61 need only be provided on the transport route, the transport unit 11 is provided with a mechanism for rotating an endless belt conveyor such as a motor and a device for supplying power to the motor. Since it is not necessary, the endless belt conveyor can be reliably driven with a simple configuration.

  In the present embodiment, an endless belt conveyor is described as an example of the cross sorter conveyor provided in the transport unit, but the present invention is not limited to this, and the cross sorter conveyor can be used in addition to the endless belt conveyor. It is also possible to use a roller conveyor.

  In the present embodiment, as a specific example in the case of driving the endless belt conveyor by alternately generating different magnetic poles by supplying power to the electromagnet unit and rotating the magnetized rotor provided in the moving transport unit, In addition to the case where the conveyed items are sorted into the sorting conveyor and the sorting chute, the endless belt conveyor of each conveying unit is also used when the conveyed items are sent from the conveying conveyor on the upstream side to each conveying unit. It is necessary to drive. In this case, the above-described electromagnet unit may be disposed above the magnetized rotor so that the endless belt conveyor travels at a position where the conveyed product is sent from the upstream conveyor to the conveyor unit. In addition to this, in the case where sorting conveyors and sorting chutes are provided on the left and right of the transport route, the electromagnet units may be arranged both above and below the magnetized rotor.
