A slide 13, a support shaft 17 that is coupled to the shoe slide 13 and protrudes downward, and a rotatable wheel 18 that is supported by the support shaft 17 and serves as a contact portion when the guide rail 5 is moved. And a vane 19 supported by a support shaft 17 above the wheel 18, and these are referred to as a slide shoe. Since the shoe cap 14 can be handled integrally with the shoe slide 13, it may be collectively referred to as a shoe slide, and the shoe slide in the claims may include a shoe cap.

  Note that the configuration of the slide shoe 4 is not limited to this, and includes a slidable member on the upper surface of the conveyor and a rotatable member at the lower portion of the conveyor. In short, the slide shoe 4 is interlocked with the rotatable member. Any mechanism that can move the article can be used. As shown in FIG. 3, the vane 19 below the shoe slide 13 and the wheel 18 below the vane 19 are not necessarily positioned in this order, and the upper and lower sides of the vane 19 and the wheel 18 may be interchanged. A plurality of them may be provided, and the positional relationship between the wheels and vanes in that case is not limited. Furthermore, the above may be configured as individual parts or as an integral part.

Will be led to 7. In this way, the branching operation is completed without the vane 19 colliding with the nose block 29. Further, when no external force is applied to the vane 19, the vane does not rotate to the branch side, the wheel 18 also goes straight, and no branching occurs.

  As shown above, by applying an external force to the vane 19 and tilting its tip slightly to the branch side, the article 6 can be guided to the branch path 7 through the slide shoe 4 without occurrence of a collision. The details, that is, the outline of applying an external force to the vane 19 according to the first embodiment will be described with reference to FIGS. 3, 4, and 5.

Light is irradiated on the surface. Then, the photovoltaic generator b2 generates power, and as shown in FIG. 7, the electrical energy is guided to the V electromagnetic coil L2 inside the vane 19 to temporarily generate a magnetic field in the V magnetic body 192. At this time, if the magnetic field polarities of the S magnetic body 132 and the V magnetic body 192 are set to be different, both are attracted. Thereby, the V magnetic body 192 of the vane 19 is attracted to the S magnetic body 132 side, the tip of the vane 19 is directed in the branching direction, and the article is branched by the shoe slide 13.

  Note that a current limiting circuit or the like may be added to the electromagnetic circuit including the battery b1 and the S electromagnetic coil L1. Also, control to generate a magnetic field may be performed only when necessary. Further, the S magnetic body 132 and the V magnetic body 192 are not particularly required as long as a sufficient magnetic flux can be obtained only by the S electromagnetic coil L1 and the V electromagnetic coil L2. Note that a plurality of light emitters 231 may be provided as necessary.

  Next, a third embodiment will be described. In the third embodiment, as shown in FIG. 8, the place where the magnetic field is generated by the permanent magnet in the case of the first embodiment is replaced with the place where the magnetic field is generated by the light emitter and the electromagnetic coil connected thereto. It is a thing.

  In the third embodiment, when the article 6 is rotated to the branch path 7 side, when the slide shoe 4 reaches a predetermined place by the method similar to that shown in FIG. Light is applied to the surface of the vane 19. Then, the photovoltaic generator b2 generates power, and as shown in FIG. 8, the electrical energy is guided to the V electromagnetic coil L2 inside the vane 19 to temporarily generate a magnetic field in the V magnetic body 192. At this time, if the permanent magnet M1 and the V magnetic body 192 are set to have different magnetic field polarities, both are attracted. As a result, the V magnetic body 192 of the vane 19 is attracted to the permanent magnet M1 side of the slide shoe 4, the tip of the vane 19 is directed in the branching direction, and the article is branched by the shoe slide 13.

  The V magnetic body 192 may not be provided as long as a sufficient magnetic flux can be obtained only by the V electromagnetic coil L2. A plurality of light emitters 231 may be provided as necessary.

  Next, a fourth embodiment will be described. In the fourth embodiment, as shown in FIG. 9, the vane 19 is provided with a permanent magnet M1 and a photovoltaic generator b2. The electrical energy generated by the photovoltaic generator b2 is guided to the V electromagnetic coil L2 installed on the shoe slide 13 side to generate a magnetic field in the electromagnetic body 192.

  In the fourth embodiment, when the article 6 is rotated to the branch path 7 side, when the slide shoe 4 reaches a predetermined place by the method similar to that shown in FIG. Light is applied to the surface of the vane 19. Then, the photovoltaic generator b2 generates electric power, and as shown in FIG. 9, the electrical energy is guided to the V electromagnetic coil L2 inside the shoe slide 13, and a magnetic field is temporarily generated in the V magnetic body 192. At this time, if the permanent magnet M1 and the V magnetic body 192 are set to have different magnetic field polarities, the permanent magnet M1 of the vane 19 is attracted to the V magnetic body 192 side of the shoe slide 13 so that the first The article is rotated as in the embodiment.

  Furthermore, the V magnetic body 192 may not be provided as long as a sufficient magnetic flux can be obtained only by the V electromagnetic coil L2. Note that a plurality of light emitters 231 may be provided as necessary.

  Next, a fifth embodiment using both a magnetic field generated by a battery and a magnetic field generated by a permanent magnet will be described with reference to FIGS. FIG. 6 is a plan view showing this turning pattern. FIG. 6 is a view of the shoe slide 13 seen from below, and is a view seen through the wheel 18 so that the vane can be seen. As shown in FIGS. 4 and 10, the photovoltaic generator b 2, the V electromagnetic coil L 2, and the V electromagnetic body 192 are installed on the vane 19, and the battery b 1, the S electromagnetic coil L 1, and the S electromagnetic body 132 are installed on the shoe slide 13. Further, a permanent magnet M1 is installed.

  The permanent magnet M1 is disposed at a position facing the S electromagnetic body 132 as shown in FIG. 10, and the polarities of the magnetic fields of the S electromagnetic body 132 and the permanent magnet M1 by the S electromagnetic coil L1 are reversed. When light is applied to the photovoltaic generator b2 of the vane 19 to generate power, the V electromagnetic body 192 of the vane 19 is attracted to the S electromagnetic body 132 side and repels the permanent magnet M1, and the tip of the vane 19 is applied with a greater force. Will rotate to the branch side.

  It should be noted that when light is applied to the photovoltaic power generator, it is only necessary to generate a force that finally rotates the vane to the branch side, and the positions of the S magnetic body 132 and the permanent magnet M1 are set at predetermined positions. Any distance and positional relationship may be used as long as force can be obtained. Further, instead of generating a magnetic field in the magnetic body by the battery b1 and the S electromagnetic coil L1, a permanent magnet may be used, or both may be a battery, an electromagnetic coil, and a magnetic body.

  In the fifth embodiment, when the article 6 is rotated to the branch path 7 side, when the slide shoe 4 reaches a predetermined place by the method similar to that shown in FIG. Light is applied to the surface of the vane 19. Then, the photovoltaic generator b2 generates power, and as shown in FIG. 10, the electrical energy is guided to the V electromagnetic coil L2 inside the vane 19 to temporarily generate a magnetic field in the V magnetic body 192. At this time, if the magnetic field polarities of the S magnetic body 132 and the V magnetic body 192 are different and the polarity with the permanent magnet M1 is set to be the same, the S magnetic body 132 and the V magnetic body 192 are attracted. Then, the S magnetic body 132 and the permanent magnet M1 are repelled. As a result, the tip of the vane 19 is sucked to the branch side, so that the article is rotated as in the first embodiment.

  Note that a current limiting circuit or the like may be added to the electromagnetic circuit including the battery b1 and the S electromagnetic coil L1. Also, control to generate a magnetic field may be performed only when necessary. Further, the S magnetic body 132 and the V magnetic body 192 are not particularly required as long as a sufficient magnetic flux can be obtained only by the S electromagnetic coil L1 and the V electromagnetic coil L2. Note that a plurality of light emitters 231 may be provided as necessary, for example, when branched to both sides.

  In the description so far, the magnetic field is generated by the photovoltaic generator, but the magnetic field may be generated by energy transmission means other than light. Alternatively, energy from the outside may be stored and an electromagnetic circuit for branching may be activated by light, radio waves, ultrasonic waves, or the like. Further, another power source may be used instead of the battery.

  In addition, as a power source, it is also possible to generate electricity by incorporating a generator in the wheel of the slide shoe, and store the obtained electric power in a capacitor (condenser) built in the slide shoe and use it. Large power may be obtained.

  Furthermore, by rotating the vane by rotating the vane by using pressure other than magnetic field, pressure by gas, liquid, physical contact force, use of shape memory alloy or springy resin, use of piezo element, etc. It doesn't matter.

  Next, a sixth embodiment will be described with reference to FIG.

In addition, the shoe slide 13 is provided with a battery 21 as a driving source (power source), a photovoltaic power generation body b2, and a photocurrent detection switch 22.

  Here, an electric circuit for connecting the stepping motor 20, the battery 21, and the photocurrent detection switch 22 is formed. Further, the photovoltaic generator b2 is associated to operate the photocurrent detection switch 22. A light emitter 231 (not shown) is provided outside.

  The operation of the sixth embodiment having such a configuration is as follows. When the slide shoe 4 needs to be branched, the light emitter 231 emits light toward the photovoltaic generator b2. Then, an electromotive force is generated thereby, and this is transmitted to the photocurrent detection switch 22. Then, the photocurrent detection switch 22 is activated, the circuit of the stepping motor 20 -battery 21 -photocurrent detection switch 22 is closed, the current from the battery is transmitted to the stepping motor 20, and the connection of the stepping motor 20 is caused by the rotation of the stepping motor 20. The vane 19 is rotated.

  Note that the rotation angle of the vane 19 is given to the stepping motor 20 by a control unit (not shown) or is based on a mechanical vane angle regulating mechanism (not shown).

  Further, the rotation drive unit is not limited to the stepping motor, and any other mechanism may be used as long as it can be rotated by energization, such as other motors and solenoids. For example, an electromagnetic powder clutch may be used.

  The photocurrent detection switch 22 may be any switch as long as it can perform the function of opening and closing the circuit by the electromotive force of the photovoltaic generator 231, and may be configured integrally with the photovoltaic generator for mounting. Good.

  In the description so far, there is a case where an operation of returning to the initial position is necessary after the rotation of the vane 19. In this case, a coil spring or the like is arranged coaxially with the vane 19 or outside the vane 19. An elastic body such as a leaf spring may be added.

  In the above description, various components are independent components. However, a composite component in which some of these components are combined may be used. Any name, shape, and the like are included in the scope of the technical idea of the present invention as long as they can substantially function as independent components.

  The present invention can be applied to prevent an event that generally occurs when an object driven by an external magnetic force is insufficiently operated. Therefore, it has sufficient possibility of being used in the distribution industry.
