  However, in the conventional transport facility, a part of the downstream side wall on the downstream side is formed of a nonmagnetic material, and the roller guided by the branch rail does not go around the end of the permanent magnet due to the magnetic force of the permanent magnet. However, there is a problem that a separate member is required.

  In addition, an electromagnet and a permanent magnet are arranged from the upstream side at the branching portion of the branch rail with the main rail, a gap is provided between the electromagnet and the permanent magnet, the permanent magnet's magnetic force passes through the electromagnet, and the electromagnet is energized. Measures have been taken to prevent the rollers from being drawn when there is not (especially at low speeds or acceleration / deceleration), but conversely, because of the gaps, there is a risk that the rollers will not be drawn and the rollers will not be branched rails. (Especially at high speeds).

  Therefore, the present invention can prevent the roller from wrapping around the end of the permanent magnet due to the magnetic force of the permanent magnet without increasing the number of members at the branching portion between the branch rail and the main rail, and can reliably rotate the roller even at a high speed. The purpose is to provide a transfer facility that can be branched.

In order to achieve the above-mentioned object, the invention described in claim 1 of the present invention is provided with a plurality of article supports for carrying and carrying articles on an endless rotating body arranged along a conveyance path, Each article support is provided with an article laterally pushing body that is guided by being externally fitted to the article support and acts on the side of the article on the article support, and the article support is driven by driving the endless rotating body. A transport facility for moving a body along the transport path and transporting an article supported by the article support in the transport direction;
A linear guide portion for providing a guided body having at least an outermost layer made of a magnetic material at a lower portion of each article laterally pushing body, and guiding the guided body in a straight direction along the transport path; A branch guide part is provided that branches from the straight guide part and guides in a direction orthogonal to the conveyance path, and distributes the guided body to the straight guide part and the branch guide part at the start end of the branch guide part. A first magnet unit that functions as an electromagnet in order from the upstream side to act on the magnetic body of the guided body and guides the guided body toward the branch guide section, and a permanent magnet. A second magnet part that functions and acts on the magnetic body of the guided body and guides the guided body toward the branch guide part is arranged, and the second magnet part is a lower blade made of a plate-like magnetic body. And laminated on this lower blade A plate-like permanent magnet and an upper blade made of a plate-like magnetic material laminated on the permanent magnet, and the lower blade is extended downstream and formed longer than the permanent magnet. To do.

  According to the above configuration, when the article lateral pusher is guided in a direction orthogonal to the conveyance path and the article on the article support is carried out to the side, the guided body of the article lateral pusher is branched and guided by the sorting means. Guide to the department. At this time, the guided body is attracted by the function of the first magnet part as an electromagnet, and then attracted by the function of the second magnet part as a permanent magnet. In the second magnet unit, the magnetic flux generated by the permanent magnet is linked to the magnetic body of the guided body via the upper blade (or lower blade), and the interlinked magnetic flux is transferred from the lower blade (or upper blade) to the permanent magnet. Thus, the guided body is attracted to the second magnet portion by the attraction force generated at that time.

  Further, since the lower blade of the second magnet part is extended, the attracting force is weakened when the guided body is guided by the extended part, and when the guided body comes out of the extended part, the guided body becomes the second magnet. It is prevented from going around the part. In this way, by extending the lower blade of the second magnet portion, it is possible to eliminate the need to arrange other members and prevent the guided body from wrapping around.

  The invention according to claim 2 is the invention according to claim 1, wherein the first magnet portion is provided in a lower blade made of a plate-like magnetic body and a central portion of the upper surface of the lower blade. The first magnet includes a plate-shaped iron core, a coil wound around the outer peripheral surface of the iron core, and an upper blade made of a plate-shaped magnetic body disposed so as to sandwich the iron core and the coil together with the lower blade. Ends of the lower blades of the first and second magnet parts on the side of guiding the guided body are bent upward, and the upper blades of the first and second magnet parts are guided on the guided body. The guide portion of the guided body is formed by bending the end portion of the guide member downward.

  According to the above configuration, when the coil is energized, a magnetic flux is generated in the iron core, and the generated magnetic flux is linked from the iron core to the magnetic body of the guided body via the upper blade (or the lower blade). From the blade (or upper blade) to the iron core, the guided body is attracted to the first magnet portion by the attraction force generated at that time.

In addition, the guided body is stably moved by bending the end of each blade to form the guided surface of the guided body.
The invention according to claim 3 is the invention according to claim 1 or 2, wherein the downstream end portion of the first magnet portion and the upstream end portion of the second magnet portion are opposed to each other. In this way, it is characterized in that it is cut diagonally and the diagonal cutout portions are arranged to face each other.

  According to the above configuration, by arranging the oblique notch portions to face each other, a gap is formed between the first magnet portion and the second magnet portion, and the magnetic force of the second magnet portion flows to the first magnet portion and is first. The guided body is prevented from being attracted even if the magnet part is not energized, and the guided body is always driven by the magnetic force of either the first magnet part or the second magnet part in these oblique notches. It is sucked and the separation of adsorption is prevented.

  Since the lower blade of the second magnet unit is extended when the guided body is sequentially attracted to the first magnet unit and the second magnet unit, the conveyance facility according to the present invention is configured so that the guided body is When guided, the attraction force (magnetic force) becomes weak, and when the guided body comes out of the extension portion, the guided body can be prevented from wrapping around the second magnet portion, and other members can be arranged to arrange the guided body. There is an effect that it is possible to eliminate the need to prevent the wraparound and reduce the cost.

  As shown in detail in FIGS. 1 to 3, the suction device 72 is provided on an aluminum mounting base 74, and functions in turn as an electromagnet from the upstream side to act on the magnetic body 59 a of the guide roller 59. The first magnet portion 75 that guides the guide roller 59 and the second magnet portion 76 that functions as a permanent magnet and acts on the magnetic body 59a of the guide roller 59 to guide the guide roller 59 are arranged.

  The first magnet unit 75 is downstream of the alignment support shaft guide 71, and is a turning point 79 between a straight path 77 in which the article laterally pushing body 57 (guide roller 59) goes straight and a branch path 78 that branches to the moving guide rail 64. The second magnet part 76 is arranged along the branch path 78 continuously to the first magnet part 75. The second magnet part 75 is arranged along the straight path 77 on the upstream side and the branch path 78 on the downstream side.

  The first magnet portion 75 is wound around a lower blade 80 made of a thin plate-shaped magnetic body, a thin plate-shaped iron core 81 provided at the center of the upper surface of the lower blade 80, and an outer peripheral surface of the iron core 81. The coil 82 and the lower blade 80 are composed of a thin plate-like magnetic body disposed so as to sandwich the iron core 81 and the coil 82 together with the lower blade 80, and an end portion of the lower blade 80 on the side for guiding the guide roller 59 is provided. A side (guide surface) 80a is formed by bending upward, and an end of the upper blade 83 on the side for guiding the guide roller 59 is bent downward to form a side (guide surface) 83a. Guide surfaces 80a and 83a are opposed to each other to form slits 84 and filled with resin 85 inside. As described above, the iron core 81 and the coil 82 are disposed between the lower blade 80 and the upper blade 83, and the slit 84 is provided on the side where the guide roller 59 is guided. The generated magnetic flux is linked from the iron core 81 to the magnetic body 59a of the guide roller 59 via the upper blade 83 (or the lower blade 80), and the interlinked magnetic flux is fed from the lower blade 80 (or the upper blade 83) to the iron core. 81, the guide roller 59 is attracted to the first magnet unit 75 by the attraction force generated at that time. That is, by supplying power to the coil 82, the first magnet unit 75 functions as an electromagnet and attracts the guide roller 59. Further, when the guide roller 59 is attracted to and moved by the first magnet portion 75, it is stably moved by being guided by the side portions (guide surfaces) 80a and 83a of the first magnet portion 75.

  The second magnet portion 76 is laminated on the lower blade 87 made of a thin plate-like magnetic body, the thin plate-like permanent magnet 88 laminated on the lower blade 87, and the permanent magnet 88. It is composed of an upper blade 89 made of a thin plate-like magnetic material, and the end of the lower blade 87 that guides the guide roller 59 is bent upward to form a side portion (guide surface) 87a. The end of the upper blade 89 on the guiding side is bent downward to form a side (guide surface) 89a, and the ends of these side (guide surfaces) 87a and 89a are opposed to form a slit 90. As described above, the lower blade 87, the permanent magnet 88, and the upper blade 89 are provided so as to be laminated, so that the magnetic flux generated by the permanent magnet 88 is transmitted through the upper blade 89 (or the lower blade 87) to the magnetic body of the guide roller 59. The magnetic flux interlinked with 59 a reaches the permanent magnet 88 from the lower blade 87 (or the upper blade 89), and the guide roller 59 is attracted to the second magnet portion 76 by the attractive force generated at that time. Further, when the guide roller 59 is attracted to and moved by the second magnet portion 76, it is stably moved by being guided by the side portions (guide surfaces) 87a and 89a of the second magnet portion 76. Further, the lower blade 87 of the second magnet portion 76 is provided with an extended portion 87b extending downstream, and the lower blade 87 is formed longer than the permanent magnet 88 and the upper blade 89 only by this extended portion 87b. ing. In the extension portion 87b, the attractive force (magnetic force) acting on the guide roller 59 is reduced.

  Further, as shown in FIG. 3, the downstream end portion 75a of the first magnet portion 75 and the upstream end portion 76a of the second magnet portion 76 are notched obliquely so as to oppose each other, and the oblique notch portions are opposed vertically. As described above, the gap 91 is provided obliquely. The slits 84 and 90 are continuous.

  With the configuration of the suction device 72, the guide roller 59 is attracted by the first magnet unit 75 when it is supplied with power to the coil 82 (guided so as to incline toward the branch paths B and C), and the first magnet unit 75. Are guided by the side portions (guide surfaces) 80a and 83a of the second magnet portion 76, moved along the slit 84, and subsequently attracted by the second magnet portion 76 and guided by the side portions (guide surfaces) 87a and 89a of the second magnet portion 76. While moving along 90, the roller shaft 58 is guided by the start end guide 73, guided by the moving guide rail 64, and moved inward. As a result, the article laterally pushing body 57 crosses the main transport path A while moving in the transport direction, and acts laterally on the article D to change the direction of the article D to the main transport path A. On the other hand, it is branched and moved in an inclined state, and passed to the other branch conveyor 17.

  When the guide roller 59 moves along the second magnet portion 76, it moves along the extension 87b of the lower blade 87 at the downstream end. Since the extension portion 87b reduces the attractive force acting on the guide roller 59, when the guide roller 59 passes through the extension portion 87b, it is prevented from turning inward from the downstream end portion of the second magnet portion 76.

  Further, when the guide roller 59 moves from the first magnet portion 75 to the second magnet portion 76, the diagonal cutout portions are arranged to face each other, and a gap 91 is formed between the first magnet portion 75 and the second magnet portion 76. As a result, the magnetic force of the second magnet portion 76 flows to the first magnet portion 75 and the guide roller 59 is prevented from being attracted when the first magnet portion 75 is not energized. The guide roller 59 is always attracted by the magnetic force of one of the first magnet portion 75 and the second magnet portion 76 to prevent the adsorption from being separated.

Further, when the coil 82 is not supplied with power, the guide roller 59 goes straight without being attracted by the first magnet portion 75, and the article laterally pushing body 57 passes (does not branch and move).
In this way, the article side pusher 57 is distributed to the main transport path A or the branch paths B and C by the forward branch guide unit 61.

  Further, as shown in FIG. 12, the article support 50 is moved by the forward branch guide 61 on the return path in which the article support 50 moves in the direction opposite to the conveyance direction of the article D and on the horizontal connecting member 15 of the lower frame member 25. A return path guide portion 67 for moving and aligning the article laterally pushing body 57 to one side in the left-right direction is provided. The return path guide unit 67 returns (guides) the guide roller 59 of the article laterally pushing body 57 to the one side (the side opposite to the branch paths B and C), and from the other side (the branch paths B and C side). A moving guide rail 68 that inclines inward toward the downstream side and reaches one side (the side opposite to the branch paths B and C), and a guide roller of the article laterally pressing body 57 disposed at the end of the moving guide rail 68. 59, and a return guide rail 69 for guiding 59 straight.

The operation of conveying and branching the article D according to the above configuration will be described.
The both endless chains 40 are moved by operating the electric motor 35 of the drive device 34 and forcibly rotating the drive sprocket 39 via the drive shaft 31 interlocked with the speed reducer 36. By moving the both endless chains 40, the article support 50 group is supported and guided on the upward support surfaces of the guide rail portions 22 and 26 via the rotating body 55, and the outward guide rail portion 22 is connected via the side rollers 56. Further, the article support 50 group moves in a stable state by being guided by the lateral guide surface of the upper end extension 29. As a result, the article support 50 group circulates and moves, so that the article D supplied onto the starting article support 50 group is conveyed along the main conveyance path A.

  When such conveyance is performed, the article laterally pushing body 57 that moves integrally with the article support 50 group is guided by the guide roller 59 by the forward branch guide 61 and the backward guide 67. It reciprocates in the length direction 51 of the support body 50, or moves linearly along the main transport path A together with the article support body 50. At that time, the reciprocating movement of the article laterally pushing body 57 is in a state of being guided by the article support body 50, that is, in a state where a suitable sliding friction is generated, and there is no backlash and the posture (orientation) changes greatly. It can always be performed stably.

  That is, the guide roller 59 guided by the start guide rail 62 is guided straight when the first magnet portion 75 of the distribution means 63 does not generate a magnetic force (when the magnetic body 59a of the guide roller 59 is not attracted). Subsequently, the vehicle travels straight while being guided by the intermediate guide rail 66. As a result, the article lateral pusher 57 does not act on the article D, and the article D is conveyed in a straight line on the main conveyance path A.

  The guide roller 59 guided by the start guide rail 62 is supplied with power to the coil 82 of the suction device 72 when the first magnet portion 75 of the distribution means 63 exerts an attracting action on the magnetic body 59a of the guide roller 59. At this time, the magnetic force of the first magnet portion 75 and the second magnet portion 76 of the suction device 72 is attracted from the start guide rail 62 to the moving guide rail 64 side. Then, first, the roller shaft 58 is guided by the start end guide 73, and subsequently, the guide roller 59 is guided to the moving guide rail 64, guided to the moving guide rail 64, moved inward, and guided to the end guide rail 65. Is done. As a result, the group of article laterally pushing bodies 57 crosses the main transport path A while moving in the transportation direction, and the group of article laterally pushing bodies 57 acts laterally against the article D, causing the article D to change its direction. While changing, it is branched and moved with respect to the main transport path A and is transferred to the outer branch conveyor 17.

  The guide roller 59 that has reached the end of the end guide rail 65 in this way is reversed at the end of the main transport path A. In the return path guide section 67, first, it is guided by the movement guide rail 68 and moved to the one side, reaches the return guide rail 69, and is aligned on one side.

When the roller 59 is attracted by the first magnet unit 75 and the second magnet unit 76, the roller 59 can be stably moved.

  Moreover, according to this Embodiment, the notch location of the 1st magnet part 75 and the 2nd magnet part 76 was arrange | positioned facing, and the clearance gap 91 was formed between the 1st magnet part 75 and the 2nd magnet part 76. This prevents the guide roller 59 from being attracted when the magnetic force of the second magnet part 76 flows to the first magnet part 75 and the first magnet part 75 is not energized. The roller 59 can be attracted by the magnetic force of either the first magnet portion 75 or the second magnet portion 76, and can prevent the adsorption from being separated.

  In the present embodiment, as shown in FIG. 3, the gap 91 between the first magnet portion 75 and the second magnet portion 76 is formed so as to be inclined downward from the upstream side to the downstream side. 13, as shown in FIG. 13, it is formed so as to be inclined downward from the downstream side to the upstream side, or the inclination of the gap between the lower blades 80 and 87 and the gap between the upper blades 83 and 89 is reversed. You may form so that it may become.

In the embodiment, at least the outermost layer of the guide roller 59 is configured as a magnetic body 59a, but the entire guide roller 59 may be configured as a magnetic body.
In the embodiment, the article support 50 is a slat configured in a mold rail shape. However, the article support 50 is not limited to a mold rail shape, and may be a cylindrical shape or a rod shape. Anything that can be supported is acceptable.

  In the embodiment, as shown in FIGS. 6 and 7, the article D is carried out to the branch paths B and C on the right side in the conveyance direction from the main conveyance path A by the action of the article lateral pusher 57. As shown in FIG. 14A, the article D can be carried out to the right branch path B or the left branch path E according to the flow of conveyance, and arranged at the same position as shown in FIG. One of the right branch path B and the left branch path E can be selected and carried out. Further, as shown in FIG. 14C, the article D carried in from a plurality of (two in the figure) carry-in paths F arranged in parallel at the upstream end of the main transport path A by the action of the article side pusher 57. , The position of the article D can be moved in accordance with the position of the carry-out path G while the article D is being carried, or when the article D is carried out to the single carry-out path G arranged at the downstream end, or FIG. As shown in (d), a plurality of (two in the figure) unloading of articles D loaded from one loading path F arranged at the upstream end of the main conveying path A are arranged in parallel at the downstream end. When selecting and carrying out to the path | route G, it can also be made to move according to the one carrying-out path | route G which selected the position of the article | item D during conveyance. Further, as shown in FIG. 14 (e), the position of the article D being conveyed along the main conveyance path A can be simply moved in the left-right direction by the action of the article lateral pusher 57. In FIGS. 14C to 14E, the plurality of article laterally pushing bodies 57 are simultaneously moved in the left-right direction to move the article D in parallel, but these are shown in FIGS. 14A and 14B. As described above, it is also possible to move the plurality of article laterally pushing bodies 57 obliquely in order and move the article D obliquely to a desired left and right position.
