Description

  The present invention relates to a conversion facility used, for example, for transferring an article being conveyed on a main conveyance path to a branch conveyance path provided outside the side of the main conveyance path.

Conventionally, the following configuration is provided as this type. That is, the rotating body of the moving means provided slidably on the slat is formed of a ferromagnetic material, and this rotating body is guided to a guide rail composed of a main rail and a branch rail laid on the lower surface of the conveyor. . An electromagnet and a magnet are arranged at the downstream side of the branch rail with the main rail. When conveying an article in the branching direction, the electromagnet is energized to attract the rotating body, and then moved along the magnet to guide the branching rail (see, for example, Patent Document 1).

In this case, the rotating body is separated (displaced) from the electromagnet. ) When guided on the side, there is a possibility that the suction of the rotating body by the electromagnet is disturbed. Further, slightly upstream of the branching portion, the rotating body is guided by one guide rail side wall of the guide rail, and the support shaft is guided by the support guide member disposed on the other side. Since the same surface of the support shaft (the arcuate side surface on the other side) is always slidably guided by the support shaft guide member, wear of the support shaft becomes severe and the replacement frequency including expensive rotating bodies is high. In some cases, the sliding member is replaced in units.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a conversion facility capable of always suitably distributing and reducing wear on the guided body side during distribution.

At this time, the left-right swing angle restricted by the suction side guide portions 101A and 101B and the stopper portions 105A and 105B is set to a small angle of about 1 degree, for example. The above 91A, 91B to 109A, 109B, etc. constitute an example of the sorting means 90A, 90B.

  Permanent magnets 111A and 111B are provided on the lower side of the attracting side guide portions 101A and 101B. When the magnetic material 66a of the guide roller 66 is attracted by the permanent magnets 111A and 111B, the guide roller 66 is guided inward. It is configured as follows. That is, the side surfaces of the permanent magnets 111A and 111B are formed on the suction side surface 111n that is continuous with the suction side surface 101n of the suction side guide portions 101A and 101B.

  As shown in FIGS. 1 and 4, distribution guide bodies 115 </ b> A and 115 </ b> B are provided on the lower side of the distribution means 90 </ b> A and 90 </ b> B so as to act on the lower end protruding portion of the roller shaft 65 and guide in the distribution direction. . Here, the outer side surfaces of the sorting guide bodies 115A and 115B are formed as straight traveling guide surfaces 115m parallel to the start ends of the intermediate guide portions 75A and 75B, and the inner side surfaces are the same as the attracting side surfaces 111n of the permanent magnets 111A and 111B. It is formed on the inclined guide surface 115n inclined in the direction. Further, width-adjusting guide portions 118A and 118B for guiding the guide roller 66 in a width-adjusting manner are provided on the upper side of the distributing means 90A and 90B. Here, the width adjusting guide portions 118A and 118B are composed of a pair of left and right guide bodies, and at this time, the front half portion is gradually inclined to receive and guide the guide rollers 66 from the start end guide portions 71A and 71B. In addition, the latter half portion is formed on a parallel guide surface for passing the guide roller 66 to the fitting grooves 92A and 92B of the fitting guide portions 91A and 91B.

  As shown in FIG. 2, reverse guide bodies 120A, 120B, 121A, and 121B that allow the guide rollers 66 to be fitted are attached to the shafts 30 and 31 so that the guide rollers 66 are guided at the reverse portions at the beginning and end. It has been. As shown in FIGS. 7 and 8, the upper frame material 10 (upper part of the main body frame 1) has an endless chain 40 and a portion formed with the forward guide rail portion 18. A cover body (chain cover) 123 for closing the upper portion of the guide roller 56 is disposed. This cover body 123 is formed in a reverse L-shaped mold rail shape in cross section. The cover body 123 is detachably fixed to the upright portion 11 of the upper frame material 10 by a connector 124 made of a bolt and a nut using the outward groove portion 14.

  As shown in FIG. 2, branch conveyors 127 </ b> A and 127 </ b> B that form branch transport paths 126 </ b> A and 126 </ b> B that are inclined outward and inferior to the main transport path 45 are provided on both outer sides of the main body frame 1. . These branch conveyors 127A and 127B are configured by supporting a number of rollers on a conveyor frame. Reference numeral 130 denotes an article.

Hereinafter, in the first embodiment described above, the conveyance and branching operations of the article 130 will be described.
Both endless chains 40 can be moved (turned) by operating the electric motor 35 of the drive device 34 and forcibly rotating the sprocket 39 via the drive shaft 31 interlocked with the speed reducer 36. The movement of the both endless chains 40 causes the article support 50 group to be supported and guided on the upward support surfaces of the guide rail portions 18 and 26 via the guide rollers 56, and the guide rail portions 18 of the both guide rail portions 18 are supported via the side rollers 57. It can move in a stable state by guiding it to the lateral guide surface. As a result, the article support 50 group circulates and moves, so that the article 130 supplied onto the article placement surface 52 of the starting article support 50 group can be conveyed on the main conveyance path 45. At the time of conveyance, the movement of both endless chains 40 in the forward path is performed below the cover body 123 and above the lubricating oil receiver 13, and the movement of both endless chains 40 in the return path is performed by the upper end extension 29. And above the lubricating oil receiver 25.

  When such conveyance is performed, the article laterally pressing body 60 that moves integrally with the article support 50 group is guided by the guide device groups 70 and 76, so that the article support body 50. It reciprocates in the length direction 51 or moves linearly along the main transport path 45 together with the article support 50. That is, in FIG. 4, for example, the guide roller 66 guided by the one-side starting end guide portion 71A is linearly guided when the distribution means 90A is in the linear distribution state, and is linearly moved while being guided by the intermediate guide portion 75A. After that, it is guided to the end guide part 74A. As a result, the article laterally pressing body 60 does not act on the article 130, and the article 130 is conveyed in a straight line on the main conveyance path 45. The same applies to the opposite side, and the guide roller 66 of the start end guide portion 71B is guided by the intermediate guide portion 75B from the distributing means 90B and moves straight to the end guide portion 74B.

  Further, the guide roller 66 guided to the one-side starting end guide portion 71A is guided to be inclined inward when the distribution means 90A is in the inclined distribution state, and is guided to the inner movement guide portion 72A to be moved inward. After that, it moves to the outer movement guide part 73B via the upper switching means 85, is guided by this outer movement guide part 73B, is moved outward, and is then guided to the terminal guide part 74B. As a result, the group of article laterally pressing bodies 60 crosses the main transport path 45 while moving in the transporting direction, so that the lateral side pushing action part 62 on the other side contacts the article 130 via the laterally pushing contact member 64. By laterally acting, the article 130 is branched and moved with respect to the main transport path 45 while changing its direction, and is delivered to the other branch conveyor 127B. The opposite side is the same, and the guide roller 66 of the start end guide portion 71B is guided by the sorting means 90B, the inner movement guide portion 72B, the upper switching means 85, the outer movement guide portion 73A, and the end guide portion 74A. The side pushing action part 62 on one side of the push body 60 group acts on the article 130 via the side pushing abutment member 64, and passes the article 130 to one branch conveyor 127A.

  In this way, the guide roller 66 that has reached the end portions of the end guide portions 74A and 74B is guided by the reverse guide bodies 121A and 121B to be reversed. In FIG. 5, the return path guide device 76 is first guided by the inward movement guide portions 77A and 77B and moved to the center portion, and then distributed to the left and right by the lower switching means 86, and then the outer movement guide portions 78A and 78B. It is moved outward by guidance. After that, after being guided and reversed by the reversal guide bodies 120A and 120B, it is moved to one of the start end guide portions 71A and 71B.

  The linear distribution state and the inclined distribution state in the distribution means 90A and 90B described above are performed as follows. That is, for example, in the one-side sorting means 90A, the guide roller 66 from the starting end guide portion 71A is received by the width-shifting guide portion 118A and guided while being corrected for width-alignment at the inclined guide surface portion of the first half, and the second half After being guided on the parallel guide surface of the portion, it is passed to the fitting groove 92A of the fitting guide portion 91A. At that time, the fitting guide portion 91A is in a state (free state) that can swing in the left-right direction around the vertical axis 93A because the suction side guide portion 101A has no suction action (non-excitation). . Therefore, when the guide roller 66 from the width adjusting guide portion 118A is slightly shifted in the left-right direction (shifted) and comes into contact with any of the inclined guide surfaces 92m, the guide roller 66 swings due to the contact pressure. As a result, the guide roller 66 can enter the fitting groove 92A smoothly and constantly with less contact noise regardless of the deviation.

  When the guide roller 66 is drawn and guided by the inclined guide surface 92m and then enters the parallel guide surface 92n, the roller shaft 65 is reliably detected by the detection body 94A, and the detection signal is transmitted to the control device via the wiring 96A. Be put in. At this time, when the guide roller 66 of the article support 50 that has reached the fitting groove 92A (the sorting means 90A) is not intended, the whole is controlled by the control device, and the suction side guide portion 101A from the control device. Is not energized, and therefore the suction side guide portion 101A is off and no suction action occurs.

  Therefore, as shown in FIGS. 9 and 11, the guide roller 66 has come out of the fitting groove 92 </ b> A of the fitting guide portion 91 </ b> A that is swingable in the left-right direction around the longitudinal axis 93 </ b> A (free state). After that, as indicated by the imaginary line (a) in FIG. Next, the lower end protrusion of the roller shaft 65 is guided by the straight guide surface 115m of the sorting guide body 115A, so that the guide roller 66 (the article laterally pressing body 60) moves straight as shown by the imaginary line B in FIG. You will be guided.

  Further, when the guide roller 66 of the article support 50 that has reached the fitting groove 92A (the sorting means 90A) is the target, the suction side guide portion 101A is energized by the control of the control device, thereby causing the suction side. When the direction guide portion 101A is turned on, an adsorption action occurs. Accordingly, as shown in FIGS. 1 and 10, the attracting action of the attracting side guide portion 101A causes the fitting guide portion 91A to be attracted and oscillated via the magnetic body 97A, and the portion of the magnetic body 97A is related to the stepped portion 102A. They are abutted together. Thereby, the fitting guide portion 91A can be positioned, and the swing side parallel guide surface 92n which is the swing side inner surface of the fitting groove 92A is connected to the suction side surface 101n of the suction side guide portion 101A.

  Therefore, the outer peripheral surface 66b of the guide roller 66 coming out of the fitting groove 92A is attracted to the suction side surface 101n of the suction side guide portion 101A via the magnetic body 66a. At this time, the guide roller 66 is smoothly moved without impact while being idled from the continuous parallel guide surface 92n to the suction side surface 101n. 1, the guide roller 66 is guided to be inclined inward while in contact with the suction side surface 101n in the suction state and idle. Subsequently, the guide roller 66 (the article laterally pressing body 60) is inclined inward while contacting and swinging from the suction side surface 101n of the suction side guide portion 101A to the suction side surface 111n of the continuous permanent magnet 111A. In addition to being guided, the lower end protruding portion of the roller shaft 65 is guided to the inclined guide surface 115n of the distribution guide body 115A, so that the roller shaft 65 is inclined and guided inward as indicated by an imaginary line D in FIG.

As described above, the guide roller 66 (the article laterally pressing body 60) can always be properly distributed, and the fitting guide portion 91A is automatically attracted and swayed inward to prevent wear of the guide roller 66 during the distribution. Therefore, the replacement frequency of the expensive guide roller 66 or the replacement frequency in the unit of the article laterally pressing body 60 can be lowered. The above operation is performed in the same way in the other-side distribution means 130B.

  The attracting side guide portions 151A and 151B are made of electromagnets (magnet switches) and are opposed to each other at a predetermined interval. When the magnetic body 66a of the guide roller 66 is attracted, the guide roller 66 is moved to either the left or right side. It is configured to guide in one direction. That is, the side surfaces of the suction side guide portions 151A and 151B are formed as suction side surfaces 151n that are gradually separated from each other and inclined in an arc shape. At this time, the suction action is such that the guide roller 66 of the target article laterally pushing body 60 reaches the fitting groove 142, the roller shaft 65 is detected by the detecting body 144, and a detection signal is sent to the control device via the wiring. Upon entering, one of the suction side guides 151A and 151B is energized via the control device, so that either one is performed. And the fitting guide part 141 is comprised by the adsorption | suction effect | action of adsorption | suction side guide part 151A, 151B through the magnetic body 146A, 146B so that adsorption | suction rocking | fluctuation may be carried out in any one direction of right and left.

  Here, notch-shaped stepped portions 152A and 152B are formed in the upstream side portions of the suction side guide portions 151A and 151B and the suction side surface 151n, and when the fitting guide portion 141 is swung by suction, A downstream side portion of the fitting guide portion 141, that is, a portion of the magnetic bodies 146A and 146B is configured to engage with and contact with the step portions 152A and 152B. When the fitting guide portion 141 is sucked and swung, the swing-side parallel guide surface 142n, which is the swing-side inner surface of the fitting groove 142, is connected to the suction side surface 151n of the suction-side guide portions 151A and 151B.

It is configured to lead to one side. That is, the side surfaces of the permanent magnets 161A and 161B are formed on the suction side surface 161n that is continuous with the suction side surface 151n of the suction side guide portions 151A and 151B. A distribution guide body 165 that acts on the lower end protruding portion of the roller shaft 65 and guides it in the distribution direction is provided below the distribution means 140. Here, both side surfaces of the sorting guide body 165 are formed on inclined guide surfaces 165n that are inclined in the same manner as the attracting side surfaces 161n of the permanent magnets 161A and 161B.

Hereinafter, the operation of the second embodiment will be described.
The left inclined distribution state and the right inclined distribution state in the distribution unit 140 are performed as follows. That is, the guide roller 66 is received by the width alignment guide portion 118A, guided while being corrected in width alignment at the inclined guide surface portion in the first half portion thereof, and guided on the parallel guide surface in the second half portion, and then the fitting guide portion 141. To the fitting groove 142. At this time, the fitting guide part 141 is free to swing in the left-right direction around the vertical axis 143 because the suction side guide parts 151A and 151B have no suction action (non-excitation). It is in. Therefore, when the guide roller 66 from the width adjusting guide portion 118A is slightly shifted (shifted) in the left-right direction and comes into contact with any of the inclined guide surfaces 142m, the guide roller 66 swings due to the contact pressure. As a result, the guide roller 66 can be smoothly inserted into the fitting groove 142 regardless of the deviation, and can always be smoothly performed with less contact noise.

  Then, when the guide roller 66 is squeezed and guided by the inclined guide surface 142m and then enters the parallel guide surface 142n, the roller shaft 65 is reliably detected by the detection body 144, and the detection signal is sent to the control device via the wiring. Can be put. At this time, the whole is controlled by the control device, and the control of the control device is performed based on whether the guide roller 66 of the article support 50 that has reached the fitting groove 142 (the distributing means 140) is distributed to the left or right. As a result, one of the suction side guides 151A and 151B is energized, so that one of the suction side guides 151A and 151B is turned on to generate an adsorption action.

  Therefore, as shown by the solid line in FIG. 12, the attracting action of the attracting side guide portion 151B causes the fitting guide portion 141 to be attracted and swung to the right side via the magnetic body 146B, and the portion of the magnetic body 146B is moved to the stepped portion 152B. Engage and abut. Accordingly, the fitting guide portion 141 can be positioned on the right side, and the swing side parallel guide surface 142n, which is the swing side inner surface of the fitting groove 142, is connected to the suction side surface 151n of the suction side guide portion 151B.

  Therefore, the outer peripheral surface 66b of the guide roller 66 coming out of the fitting groove 142 is adsorbed to the adsorption side surface 151n of the adsorption side guide portion 151B via the magnetic body 66a. At this time, the guide roller 66 is smoothly moved without impact while being idled from the continuous parallel guide surface 142n to the suction side surface 151n. Then, the guide roller 66 is inclined and guided to the right side while making contact with the suction side surface 151n in an attracted state and swinging as shown by an imaginary line E in FIG. Subsequently, the guide roller 66 is inclined and guided to the right side while being swung in contact with the suction side surface 161n of the continuous permanent magnet 161B from the suction side surface 151n of the suction side guide portion 151B, and is rotated in the right direction. When the lower end protrusion 65 is guided by the inclined guide surface 165n of the distribution guide body 165, it is inclined and guided to the right as shown by the phantom line in FIG.

  Also, as shown by the phantom line in FIG. 12, the attracting action of the attracting side guide portion 151A causes the fitting guide portion 141 to be attracted and oscillated to the left side via the magnetic body 146A, and this magnetic body 146A portion becomes the step portion 152A. Is engaged and contacted. Accordingly, the fitting guide portion 141 can be positioned on the left side, and the swing side parallel guide surface 142n, which is the swing side inner surface of the fitting groove 142, is connected to the suction side surface 151n of the suction side guide portion 151A. Become.

  Therefore, the outer peripheral surface 66b of the guide roller 66 coming out of the fitting groove 142 is adsorbed to the adsorption side surface 151n of the adsorption side guide portion 151A via the magnetic body 66a. At this time, the guide roller 66 is smoothly moved without impact while being idled from the continuous parallel guide surface 142n to the suction side surface 151n. Then, the guide roller 66 is inclined and guided to the left side while being in contact with the suction side surface 151n side in a suction state and rotating freely. Subsequently, the guide roller 66 is guided to be tilted to the left while contacting and swinging from the attracting side surface 151n of the attracting side guide portion 151A to the attracting side surface 161n of the continuous permanent magnet 161A. The lower end protruding portion 65 is guided to the left side by being guided by the inclined guide surface 165n of the sorting guide body 165.

The minimum width of 92 W is maintained.

  The operation of this configuration is the same as that of the second embodiment described above. However, if one of the suction side guides 151A and 151B is turned on and the suction action is generated, for example, as shown by the solid line in FIG. When an attracting action is generated in the direction guide portion 151B, the right fitting guide member 171B is attracted and swung to the right side via the magnetic body 146B, and the portion of the magnetic body 146B engages and contacts the step portion 152B. At this time, the left fitting guide member 171A swings to the right side via the link member 172, so that the fitting guide part 141 can be positioned to the right side. Further, when an attracting action is generated in the left attracting side guide portion 151A, the left fitting guide member 171A is attracted and swung to the left side via the magnetic body 146A, and the portion of the magnetic body 146A is engaged with the step portion 152A.

The portion 141 is provided by the fitting groove 142 so that the guide roller 66 can be fitted and guided and can swing in the left-right direction. In the first embodiment, similarly, the fitting guide portions 91A and 91B on the upper side are respectively divided into left and right fitting guide members 171A and 171B, and these members 171A and 171B. It is also possible to provide the link member 172 to be linked so as to be swingable in the left-right direction. In addition, although the link member 172 is provided so that the outer peripheral surface 66b of the guide roller 66 may slide-contact with the left and right parallel guide surfaces 142n of the fitting groove 142, the link member 172 is eliminated and a slight gap is generated. It may be in the form of guidance.

  In the first and second embodiments described above, when the fitting guide portions 91A, 91B, 141 are sucked and swung, the parallel guide surfaces (swing side inner surfaces) 92n, 142n of the fitting grooves 92A, 92B, 142 are sucked. Although a form configured to be continuous with the suction side surfaces 101n and 151n of the side guide portions 101A, 101B, 151A, and 151B is shown, this may be a form that is connected in a state where some steps are generated.
