DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a shoe distribution device according to the present invention will be described based on the following embodiments. However, the present invention is not limited to this embodiment. FIG. 7 is a top view schematically showing a sorting conveyor. In the sorting conveyor 1, a conveying surface is constituted by a plurality of slats 2 arranged orthogonally to the conveying direction (the direction of arrow F). End blocks 3 provided at both ends in the longitudinal direction are connected to a drive chain (not shown) of the sorting conveyor 1, and the slats 2 move in the transport direction by driving the drive chain.

As shown in FIG. 8, the sorting conveyor 1 performs sorting while placing the articles Z from the conveyor A and moving them in the direction of arrow F, and the conveyor B on the downstream side.
Or C, and a return area 6 that is located on the opposite side of the transport surface of the transport area 5 and moves in the direction of arrow R. The slat 2 is provided with a guide wheel 7 that is connected to the moving shoe 4 and protrudes on the opposite side to the transport surface (slat surface). The guide wheel 7
When the slat 2 reaches the sorting position with the movement of the slat 2, for example, a Y-shaped guide rail (not shown) branched in two directions.
Is guided to the sorting mechanism 8 including While the guide wheel 7 moves on the guide rail of the sorting mechanism 8, a transport path by the moving shoe 4 as shown in FIG. 7 is formed, and desired sorting of the articles Z is performed.

After the sorting, the slats 2 move in the return area 6 and the guide wheels 7 are distributed to the left or right end in the longitudinal direction of the slats by the shoe distribution device 9 accordingly. FIG. 1 shows a first embodiment of a shoe sorting device 9 according to the present invention. The shoe distributing device 9 includes a shoe centering guide rail 10 including a pair of left and right side walls having a width slightly larger than the outer diameter of the guide wheel 7,
Arrow D following the shoe centering guide rail 10
Guide rails 11a and 11 directed in the direction and the E direction
b, a plurality of electromagnets 12 (two electromagnets 12a, 12a in the illustrated example) disposed near the entrance of a branch portion of one branch guide rail (in the illustrated example, the branched guide rail 11a);
b), and a permanent magnet 13 disposed downstream of the electromagnet 12.

As long as the electromagnet 12 is composed of a plurality of electromagnets, the number thereof and the arrangement of each electromagnet are not limited. For example, as shown in FIGS. 1 and 2, the electromagnet 12 is formed of a first electromagnet 12 a and a second electromagnet 12 b which are separate bodies, and is arranged in parallel along the branch guide rail 11 a (FIG. 2A). ) Or vertically (Fig. 2
(B)) They may be arranged side by side.

As shown in FIG. 3 (a view taken along the arrow AA in FIG. 1), a pair of upper and lower coils are wound around a single core 15 to form a first electromagnet 12a and a second electromagnet 12b. You can also. By sharing the core 15, the size of the electromagnet 12 can be reduced, and the degree of freedom in designing the branch portion can be increased. Further, a yoke 16a made of a magnetic material which forms a closed magnetic path indicated by the symbol M between the two poles of the electromagnet 12 and the guide wheel 7 of the moving shoe 4 and forms a part of the side wall of the branch guide rail 11a. , 16b may be connected.

The ends of the yokes 16a and 16b on the guide rail side may be opposed to each other in parallel, or one end (the lower yoke 16b in the example in the figure) may be inclined as shown. And a magnetic flux can be generated effectively. Further, as shown in FIG.
a and 16b are omitted, and the core 15 of the electromagnet 12 is processed so as to form a closed magnetic path with the guide wheel 7,
The first and second electromagnets 12a and 12b may be formed by winding a pair of coils around the core 15. FIG. 4 (a)
Shows a case where the coils constituting the electromagnets 12a and 12b are wound around the core 15 in parallel with respect to the guide wheel 7, while FIG. 2B shows a case where the coils are wound vertically with respect to the guide wheel 7. Things.

Here, by forming one end of the core 15 on the guide rail side as in FIG. 3, the magnetic flux can be generated effectively. Permanent magnet 13
May be a single member, or may be divided into a plurality of members and provided continuously along the branch guide rail 11a. Also, the permanent magnet 1
The magnet 3 and the electromagnet 12 may be connected by yokes 16a and 16b connected to the magnetic poles of the electromagnet 12. Further, an electromagnet can be used instead of the permanent magnet 13.

On the other hand, the guide wheel 7 moves from the upper side to the lower side (in the direction of arrow R) in the shoe sorting device 9 having the above structure in FIG. It is led to 11a or 11b. A sensor 14 for detecting passage of the guide wheel 7 is provided at an upstream end of the shoe centering guide rail 10, and controls the energization of the electromagnets 12a and 12b by calculating a passage detection signal of the guide wheel 7 and sorting information.

The shoe sorting device 9 configured as described above
When the moving shoe 4 after sorting is moved to the right end in the longitudinal direction of the slat 2 at the upstream end (upper end in the drawing) of the sorting conveyor 1 shown in FIG.
The movable shoe 4 is guided in the direction of arrow D by energizing one of the electromagnets 12a or 12b to attract the guide wheel 7 and then moving it along the permanent magnet 13 to guide it to the branch guide rail 11a. I do.

Here, the energization of the electromagnets 12a and 12b is distributed to the electromagnets 12a and 12b by switch means (not shown).
It is switched every time, every predetermined number of times, or every predetermined time. As described above, by forming the electromagnet 12 by the first and second electromagnets and alternately energizing the coils of each electromagnet, the number of energization times per electromagnet can be reduced, and the amount of heat generated by energization can be halved. it can.

On the other hand, when the moving shoe 4 is moved to the left end of the slat 2 in the longitudinal direction, the guide wheel 7 is moved straight down along the shoe centering guide rail 10 without energizing the electromagnet 12. The movable shoe 4 is guided to the branch guide rail 11b in the direction of arrow E. In the above description, the electromagnet 12 is configured by a plurality of electromagnets, and the amount of heat generated by the electromagnet 12 is reduced by sequentially switching the respective electromagnets and energizing at the time of distribution, but the electromagnet 12 and the permanent magnet 13 are provided. The same effect can be obtained by arranging a plurality of branch guide rails 11a in the same branch direction and guiding the guide wheel 7 sequentially to each branch guide rail.

Hereinafter, a second embodiment of the shoe sorting device 9 according to the present invention will be described with reference to FIG. As shown in the figure, the shoe distribution device 9 includes a shoe centering guide rail 10 and a branch guide rail 1 that is continuous with the shoe centering guide rail 10 in the directions of arrows D and E.
1a and 11b, in addition to the electromagnet 12 disposed near the entrance of the branch portion of one of the branch guide rails (the branch guide rail 11a in the illustrated example) and the permanent magnet 13 disposed downstream of the electromagnet 12, Electromagnet 12 and permanent magnet 13
And a branch guide rail 19 extending in the same direction (arrow F direction) as the branch direction of the branch guide rail 11a on the side where the electromagnet 17 and the permanent magnet 18 are disposed near the entrance of the branch portion. You.

The energization of the electromagnets 12 and 17 is alternately switched once every distribution, every predetermined number of times, or every predetermined time by switch means (not shown). Here, the shoe distribution device 9 can be variously modified. For example, as shown in the first embodiment, the electromagnet 12 and the electromagnet 17 are each composed of the first and second electromagnets. You can also. Similarly, the permanent magnets 13 and 18
May be constituted by a single member, or may be divided into a plurality of members and connected to each other along the branch guide rails 11a and 19. Also, electromagnets can be used instead of the permanent magnets 13 and 18.

The mechanism for distributing the moving shoes after sorting using the guide rails configured as described above to either the left or right end of the conveying surface of the sorting conveyor is the same as in the first embodiment. When approaching to the right end of the transfer surface, this is performed by energizing one of the electromagnets 12 and 17. For example, when the electromagnet 17 is energized,
The guide wheel 7 is attracted by energization, and then moved along the permanent magnet 18 to be guided to the branch guide rail 19.
Next, when the moving shoe 4 is moved to the right end of the transport surface, the electromagnet 12 is energized to guide the guide wheel 7 to the branch guide rail 11a. As a result, the moving shoe 4 moves in the direction of the arrow F or D and is distributed to the right end of the transport surface.

As described above, since the guide wheel 7 can be guided in the same direction regardless of whether the electromagnet 12 or the electromagnet 17 is energized, the energization per electromagnet can be performed by energizing the electromagnets 12 and 17 alternately. The number of times can be reduced, and the amount of heat generated by energization can be halved. On the other hand, in the case of approaching to the left end, the guide wheel 7 is directly moved downward in the drawing and guided to the branch guide rail 11b without energizing both the electromagnets 12 and 17. As a result, the moving shoe moves in the direction of arrow E and is distributed to the left end of the transport surface.

As described above, the shoe distribution device according to the present invention is, for convenience of explanation, an example in which the electromagnet is constituted by two electromagnets for the sake of explanation, and in the second embodiment, a branch guide rail directed to the same branch direction. Was described with two branch guide rails, but the number of electromagnets in the first embodiment and the number of branch guide rails in the second embodiment are not limited to the above embodiment as long as they are plural.
Various changes can be made.

[0030]

As described above, the shoe distributing apparatus of the sorting conveyor according to the present invention has a configuration in which a plurality of electromagnets are configured and the respective electromagnets are sequentially switched when the shoes are distributed, or the same. Since a plurality of branch guide rails extending in the branch direction are configured, and the electromagnets disposed on each branch guide rail are sequentially switched to energize, the number of energizations per electromagnet is reduced, and the amount of heat generated by energization is reduced. Can be greatly reduced as compared with the related art.

As a result, deterioration of the magnetic force of the electromagnet and combustion of the electromagnet can be prevented, the life of the apparatus can be extended, and maintenance and repair costs can be reduced.
