It is attached.

  As shown in FIGS. 6 to 8 and 13, the upper frame member 10 (upper part of the main body frame 1) is provided with an endless chain 40 and an endless guide rail portion 18. A cover body (chain cover) 140 for closing the upper side of the chain 40 and the rotating body 70 is disposed. The cover body 140 is formed in a reverse L-shaped rail shape in cross section by a side plate portion 141 and an upper plate portion 142 bent at a right angle from the upper portion of the side plate portion 141 inward. The cover body 140 has a bolt body 143 passed from the outside through the lower end portion of the side plate portion 141 in a state where the side plate portion 141 is in contact with the upright portion 11 from the outside, and is previously positioned in the outward groove portion 14. The nut body 144 can be screwed into the upright portion 11 of the upper frame material 10 so as to be detachable. At that time, the uppermost surface of the upper plate portion 142 is level with the upper surface of the article placement plate portion 54.

  As shown in FIGS. 2 and 8, branch conveyors 151 </ b> A and 151 </ b> B that form branch transport paths 150 </ b> A and 150 </ b> B that are inclined outwardly and inferior to the main transport path 45 on both sides outward of the main body frame 1. Is provided. These branch conveyors 151A and 151B are configured by supporting a number of rollers 152 on a conveyor frame. Note that the upward dovetail groove 15 or the like of the upper frame material 10 may be used for connection with the branch conveyors 151A and 151B. Reference numeral 160 denotes an article.

Hereinafter, in the above-described first embodiment, the assembly of the conveyor equipment, the conveyance of the article 160, and the branching action will be described.
When constructing the conveyor equipment, the main body frame 1 is assembled into a frame shape, and the endless chain 40 and the article support 50 are assembled into the main body frame 1, and then the cover body 140 is disposed at the upper ends of both upper frame materials 10. To do.

  That is, after inserting the pair of connecting protrusions 62A of the side bracket 61 into the pair of front and rear space portions formed on the article support 50, the inner surface side of the side bracket 61 is brought into contact with the end face side of the article support 50. The bolt body 69 passed from the outside to the through hole 63 is screwed and coupled to either of the screwing portions 55A and 55B. As a result, the side brackets 61 can be attached to both ends of the article support 50, and at that time, before the both side brackets 61 are attached or after one of the side brackets 61 is attached, the article is laterally pushed against the article support 50. The body 80 is externally fitted. Furthermore, before attaching both side brackets 61 or after attaching both side brackets 61, the cylindrical connecting body 67, the rotating body 70, and the side rollers 71 are set on the side bracket 61 side.

  That is, the cylindrical connecting body 67 is inserted into the insertion hole 65 of the cylindrical body 64 from the outside. At this time, the insertion causes the tongue piece 67C group to be elastically deformed to the cylindrical axis side, This is performed while the directional convex portion 67D group is slidably contacted with the inner peripheral surface of the insertion hole portion 65. With such insertion, as shown in FIG. 13, the flange portion 67B is positioned in contact with the outer end surface 64a of the cylindrical body 64, and the outward convex portion 67D of the tongue piece portion 67C group is inclined and enlarged in diameter. By placing the separation space L on the surface 65a so as to be opposed from the inside to be in an engaged state, the cylindrical connecting body 67 can be connected to the cylindrical body 64 with an internal fit, and thus the side bracket A cylindrical connector 67 can be set on the 61 side. And after fitting the to-be-fitted body 75 with respect to the cylindrical body 64, the rotating body 70 is fitted outside, and the retaining ring 73 is mounted | worn, and also it is a side via the longitudinal axis 72 with respect to the protrusion part 62B for support. A roller 71 is attached so as to be freely rotatable.

  Thus, after attaching the side bracket 61 to the both ends of the article support body 50, the specific long connection pin 43 in the endless chain 40 is inserted into and coupled to the cylindrical connection body 67, whereby both ends of the article support body 50 are connected. Can be coupled to the endless chain 40 via the side brackets 61, respectively. That is, as shown in FIG. 14, by moving a predetermined portion of the endless chain 40 to the outside (bending), the predetermined portion is moved to the outside through the upright portion 11, so that the long connecting pin 43 protrudes. The part is positioned above the lubricating oil receiver 13.

  And after making the protrusion part of the long connection pin 43 and the cylindrical part 67A of the cylindrical connection body 67 oppose each other, the protrusion part of the long connection pin 43 is inserted into the cylindrical part 67A from the outside. When this insertion is approaching the end, the tip of the long connecting pin 43 comes into contact with the inward convex portion 67E group. At this time, since the outward convex portion 67D is spaced apart from the inclined enlarged diameter surface 65a with the separation space L inward, the tongue piece portion 67C is deformed to the side away from the cylindrical axis against elasticity. Thus, the insertion of the long connecting pin 43 is performed while the inward protruding portion 67E group is slidably brought into contact with the outer peripheral surface of the distal end of the long connecting pin 43. And as shown in FIG. 13, the long connecting pin 43 can be couple | bonded with the side bracket 61 side by elastically engaging the inward convex part 67E of the tongue piece part 67C group with respect to the cyclic | annular recessed part 44. As shown in FIG.

  Thereby, both ends of the article support 50 can be connected to the endless chain 40 via the side brackets 61 respectively. In this case, the insertion (connection) from the outside of the long connection pin 43 can be easily and quickly performed with improved workability without being disturbed by the standing portion 11. By sequentially performing such connection, a large number of article supports 50 can be attached between the pair of left and right endless chains 40. In that case, the fitting part 66 of the side bracket 61 is externally fitted to the to-be-fitted body 75 in the adjacent side bracket 61.

  That is, as shown in FIG. 1, the external fitting is performed by relatively moving the fitting portion 66 of the side bracket 61 and the fitting body 75 of the adjacent side bracket 61 so as to be parallel to each other in the fitting portion 66. The pair of upper and lower fitting surfaces 66a is paired with a pair of flat surfaces 75a displaced by 180 degrees of the member 75 to be fitted so that there is almost no gap between them. At that time, since the flat flat surface 75a is formed at eight locations on the outer periphery of the cylindrical portion 75A, it is continuously connected to the pair of flat surfaces 75a that are closely opposed to the fitting surface 66a. The pair of flat surfaces 75a located on the fitting direction side are positioned in a slanted direction and serve as a guide, thereby causing the external fitting to be relatively moved and caught. It can always be done smoothly.

  Next, the cover body 140 is disposed on the upper ends of the upper frame members 10. That is, the bolt body 143 passed from the outside is screwed into the nut body 144 previously positioned in the outward groove portion 14 with the lower portion of the side plate portion 141 in contact with the upright portion 11 from the outside. Thus, the upper frame material 10 can be detachably fixed to the upright portion 11. Before and after the attachment of the article support 50 and the arrangement of the cover body 140, the forward guide device 110, the backward guide device 116, the upper switching device 130, the lower switching device 131, and the sorting device are provided on the main body frame 1 side. 132A, 132B, etc. are provided. Thereby, the conveyor equipment can be assembled.

  The conveyor equipment thus assembled can rotate both endless chains 40 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. By rotating the both endless chains 40, the article support 50 group is supported and guided by the upper support surfaces 18 a and 26 a of the both guide rail portions 18 and 26 via the rotating body 70, and the guide rails are connected via the side rollers 71. By being guided by the lateral guide surface 18b of the part 18 or the lateral guide surface 29a of the upper end extension 29, the guide can move in a stable state. At that time, the upper end extension 29 is positioned above the rotating body 70 on the return path side, so that the rotating body 70 can be prevented from rising, and thus the article support 50 group does not rattle up and down. Can move in a stable state. As a result, the article support 50 group circulates and moves, so that the article 160 supplied onto the starting article support 50 group can be conveyed on the main conveyance path 45.

  During transport, the movement of both endless chains 40 in the forward path is performed below the cover body 140 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 performing such conveyance, the article laterally pressing body 80 that moves integrally with the article support 50 group is guided by the guide devices 110 and 116 to guide the guided portion 91. The article support 50 is reciprocated in the longitudinal direction 51 of the article support 50, or is moved linearly along the main transport path 45 together with the article support 50.

  That is, for example, the guide roller 101 guided by the one-side start guide portion 111A is guided in a straight line when the sorting means 132A is in the linear sorting posture, and after straight running in a state in which no guide action is received, the end guide unit 114A. Will be guided to. As a result, the article laterally pressing body 80 does not act on the article 160, and the article 160 is conveyed in a straight line on the main conveyance path 45. The same applies to the opposite side, and the guide roller 101 of the start end guide portion 111B moves from the sorting means 132B to the end guide portion 114B.

  Further, the guide roller 101 guided by the one-side starting end guide portion 111A is guided to be inclined inward when the distribution means 132A is in the inclined distribution posture, and is guided to the inner movement guide portion 112A to be moved inward. After that, it moves to the outer movement guide part 113B via the upper switching means 130, and is guided by the outer movement guide part 113B and moved outward and then guided to the terminal guide part 114B. As a result, the group of article laterally pushing bodies 80 traverses the main transport path 45 while moving in the transport direction, so that the lateral side pushing action portion 85 on the other side laterally acts on the article 160 to cause the article 160 to move. While changing its direction, it is branched and moved with respect to the main transport path 45, and handed over to the other branch conveyor 151B.

  The same applies to the opposite side, and the guide roller 101 of the start end guide portion 111B is guided by the sorting means 132B, the inner movement guide portion 112B, the upper switching means 130, the outer movement guide portion 113A, and the end guide portion 114A. The lateral pushing action portion 85 on one side of the push body 80 group laterally acts on the article 160 via the transverse pushing abutting member 90, and the article 160 is delivered to one branching conveyor 151A.

  As described above, the guide roller 101 that has reached the end portions of the end guide portions 114A and 114B is guided and reversed by the reverse guide bodies 136A and 136B. In the return route guidance device 116, first, it is guided by the inner movement guide portions 117A and 117B, moved to the center portion, and then distributed to the left and right by the lower switching means 131, and then is guided to the outside by the guidance of the outer movement guide portions 118A and 118B. Moved to. After that, after being guided and reversed by the reversing guide bodies 135A and 135B, it is moved to one of the start end guide portions 111A and 111B.

  When the reversing guide bodies 135A, 135B, 136A, and 136B are guided and reversed, the front and rear side brackets 61 are relatively expanded and contracted in the rotational direction of the endless chain 40 and relatively bent. It becomes a state. In that case, relative expansion and contraction is performed in a state where the flat surface 75a of the body 75 to be fitted and the fitting surface 66a of the fitting portion 66 are in surface contact at two upper and lower positions, thereby causing rattling at the reversing portion. Further, the expansion and contraction due to the surface contact may make it difficult to wear the flat surface 75a and the fitting surface 66a which are contact portions. The relative bending is smoothly performed by the relative rotation between the cylindrical body 64 and the fitted body 75. Furthermore, since it is a surface sliding contact movement between the iron fitting portion 66 and the resin fitting object 75, that is, a surface sliding movement made of a different material, for example, compared to a surface sliding movement made of the same material, Wear and noise generation can be further reduced.

  The reciprocating movement of the article laterally pressing body 80 described above is guided and fitted to the guide portions 59 and 60 of the article support 50 via the front and rear guided portions 91 and 92, that is, the tongue piece body. In a state in which a suitable sliding friction is generated by the elastic repulsive force of the 94th and 96th groups, there is no backlash and the posture (orientation) is not greatly changed, and it can always be performed stably. Furthermore, the tongue piece bodies 94 and 96 are formed so as to be distributed to both ends in the length direction 51, so that the movement of the article laterally pushing body 80 causes the same suitable sliding friction in both reciprocations. It can be done in the state.

  As described above, when the article laterally pressing body 80 group moves in the transport direction and crosses the main transport path 45, the laterally pushing action portion 85 is laterally pushed to the article 160, and the article 160 is branched and moved. Although it is handed over to the branch conveyors 151A and 151B, the article 160 is supported between the convex parts 52 and slides on the convex parts 52. Therefore, the desired branching movement can be performed smoothly without damaging the article 160 and without wearing the article support 50 side. Further, the article 160 to be branched and moved moves over the cover body 140 fixed to the upper frame member 10 so that the upper part of the endless chain 40 is closed, so that dust or the like attached to the article 160 can be removed from the endless chain. It can prevent falling to the 40 side.

  The side portion of the lateral pushing action portion 85 is laterally abutted in a state in which the left and right corners of the front end portion 81A are formed on the arc-shaped side surface 81b, and the lateral pushing contact surface 87a is connected to the rear end of the arc-shaped side surface 81b. Since the member 87 is provided, the substantially full length of the side portion of the lateral pushing action portion 85 can be used as the lateral pushing action surface, thereby enabling stable lateral pushing movement and the front and rear article lateral pushing bodies 80. The gap S (refer to FIG. 8) between the lateral pushing action portions 85 in FIG. 8 can be reduced to enable the intended lateral pushing movement without the article 160 entering.

  Further, the upper part of the lateral pushing action part 85 is formed with an intermediate part in the front-rear direction on an inclined upper surface 86a that extends forward and downward. By forming the start-side concave arcuate upper surface 81a having a gentle angle, for example, when the article 160 is sandwiched between the front and rear article laterally pressing bodies 80 at the start of the lateral pushing, the article 160 is placed. First, the concave arcuate upper surface 81a having a gentle angle is smoothly submerged, and the article 160 is lifted by the inclined upper surface 86a. Thereby, the intended lateral pushing movement can be made possible without being pinched, and thus the article 160 and the article lateral pushing body 80 can be prevented from being damaged. In addition, since the left and right corners of the front end portion 81A are formed on the arc-shaped side surface 81b, the dive under the article 160 can be performed more smoothly.

  During operation as described above, when a force in a direction in which the endless chain 40 and the article support 50 are relatively moved apart in the longitudinal direction 51 is applied due to a secondary disaster such as a failure or an accident, that is, As shown in FIG. 15 (a), when the force in the direction in which the long connecting pin 43 and the cylindrical body 64 are relatively pulled out is applied, the cylinder that is about to be pulled out integrally with the long connecting pin 43. The outwardly projecting portion 67D group of the connecting body 67 contacts the inclined enlarged diameter surface 65a, and the inclined surface 44a contacts the inwardly protruding portion 67E group. Therefore, when the outward convex portion 67D group comes into contact with the inclined enlarged diameter surface 65a, it is possible to prevent the tubular connecting body 67 from being pulled out of the cylindrical body 64, and the inclined surface 44a contacts the inward convex portion 67E group. By making contact, it is possible to prevent the long connecting pin 43 from being pulled out of the cylindrical connecting body 67. That is, it is possible to prevent the long connecting pin 43 and the cylindrical body 64 from moving out relatively, and thus it is possible to automatically prevent a disaster such as a failure or an accident from being enlarged.

  Further, in order to perform repair or inspection work such as replacing the article laterally pressing body 80, first, the long connecting pin 43 is moved outward (disconnected) from the cylindrical body 64. At this time, as shown in FIG. 15 (b), a tool such as a screwdriver is positioned outside the flange 67B in a state where the long connecting pin 43 is coupled to the side bracket 61 side. 67B is applied with an external force P to be brought into contact with the outer end surface 64a of the cylindrical body 64, and the outward projecting portion 67D of the tongue piece portion 67C group is placed from the inner side with the separation space L with respect to the inclined enlarged diameter surface 65a. Keep them facing each other. When the long connecting pin 43 is moved outward while maintaining this state, the inclined surface 44a comes into contact with the inward convex portion 67E group, and the tongue piece portion 67C group is elastically resisted from the cylinder axis. Attempt to deform away. At this time, the outward convex portion 67D is opposed to the inclined enlarged diameter surface 65a from the inner side with a space L, so that the deformation against the elasticity of the tongue piece 67C group can be performed without any trouble. Therefore, the long connecting pin 43 can be pulled out to the outside while the cylindrical connecting body 67 is left on the side bracket 61 side. That is, extraction (connection release) to the outside of the long connection pin 43 can be performed easily and quickly with improved workability in the same manner as insertion (connection) from the outside of the long connection pin 43.

In addition, when some wear occurs on the pair of flat surfaces 75a in a long-term operation, the front and rear side brackets 61 are removed in the state where the long connecting pin 43 is pulled out (disconnected) as described above. Are moved away from each other in the rotational direction of the endless chain 40 and the fitted body 75 is extracted from the fitting portion 66, and then the fitted body 75 is rotated by a predetermined angle (45 degrees) with respect to the cylindrical body 64. By doing so, a pair of new (different) flat surfaces 75a that are not worn can be brought into surface contact with the fitting surface 66a. Therefore, in the case of the regular octagon-shaped to-be-fitted body 75, it can be used economically because it can be used by switching three times (four times in total).
[Embodiments 2 to 4]
