The body 103 is configured to be elastically deformable in the front-rear direction. A front abutting portion 103a is formed at the free ends of both forward tongue pieces 103, and the abutting portion 103a is formed to project forward from the front and rear guided surfaces 96a, thereby forming a front leg plate portion. 55 is configured to be elastically contactable from the inside.

  In the article laterally pressing body 80 having the above-described configuration, the upper plate member 81, the front plate member 82, and the rear plate member 83 are formed so that a part of the plate thickness is not uniform. That is, the front plate member 82 and the rear plate member 83 are formed so that the plate thickness gradually increases toward the opposite side (center side) as it extends downward with respect to the upper plate member 81.

That is, as described above, the front plate portion 57 and the rear plate portion 58 of the article support 50 are inclined inward (inner diaphragm shape) so as to approach each other as they extend downward with respect to the article placement plate section 54. since there, by use of the space caused by it, before the thickness t of the upper end portion of the plate member 82 and rear plate 83, the thickness T ₁ of the lower end portion is formed thick. The thickness T ₂ of the bottom plate member 84 is formed to be continuous with the thickness T ₁ of the lower end portions of the front plate member 82 and the rear plate member 83 and is formed to be continuous with the lower ends of the front plate member 82 and the rear plate member 83. as from extending to the central portion, is substantially the thickness T ₃ across the cavity 84A is formed to be gradually thicker. That is, it is formed as [t <T ₁ ≈T ₂ <T ₃ ]. Due to such a change in thickness, the overall strength of the article lateral pressing body 80 is increased without increasing (increasing) the longitudinal length of the article lateral pressing body 80.

  At that time, the bottom plate 84 is formed in a thick portion with a flat central portion and an inclined portion where the periphery gradually increases from the front and rear ends and the left and right ends, but the lower surface 84a is formed in a flat shape as a whole. Thus, it is possible to eliminate the catch with other objects. Furthermore, on the lower surface of the article laterally pressing body 80 on the upper plate member 81 side, there are three concave groove portions 104 facing the convex portion 52 formed on the article mounting plate portion 54 of the article support 50 from above.

  The cover body 140 has the lower upright plate portion 141A in contact with the upright portion 11 from the outside and with the lower end of the lower upright plate portion 141A in contact with the receiving surface 11a from above. A bolt body 145 passed from the outside to the lower end portion of 141A is screwed into a nut body 146 previously positioned in the outward groove portion 14, thereby being detachably fixed to the standing portion 11 of the upper frame material 10. obtain. At that time, the uppermost surface 142a of the horizontal plate portion 142A of the upper plate portion 142 is at a level that is flush with the upper surface 54a of the article placement plate portion 54 and slightly lower than the flat surface 52a. The inclined upper surface 142b of the end inclined portion 142B is a low position that is lowered with respect to the upper surface 54a of the article placing plate portion 54.

  As shown in FIGS. 4, 5, and 16, branch conveyors 151 </ b> A that form branch paths 150 </ b> A and 150 </ b> B that are inclined outward and inferior to the main transport path 45 on both sides outward of the main body frame 1. , 151B are provided. These branch conveyors 151A and 151B are configured by supporting a large number of rollers 153 on a conveyor frame 152. At that time, the conveyor frame 152 and the rollers 153 are positioned at the ends of the upper frame material 10 in the step 12 of the upper frame material 10. And arranged in a state of being sufficiently close to the side plate portion 141 of the cover body 140.

  Here, the branch conveyance surfaces 150a and 150b of the branch paths 150A and 150B are flush with the upper surface 54a of the article placement plate 54 and the uppermost surface 142a of the horizontal plate 142A. The end of the conveyor frame 152 is provided with a restricting body 155 for preventing unintentional movement of the cover body 140, and the inner end of the restricting body 155 contacts the upper upright plate portion 141C of the side plate portion 141. It is considered as a tangent. At that time, the restricting body 155 is connected to the conveyor frame 152 side so that the restricting position can be adjusted by screwing the screw body 157 passed through the elongated hole 156 from above to the conveyor frame 152 side. 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.

In the following, the assembly of the basic conveyor equipment described above and the conveyance and branching operations of the article 160 will be described.
When constructing the conversion 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 on the upper ends of both upper frame materials 10. Let

  That is, the pair of insertion portions 63 of the side bracket 61 are inserted into the pair of front and rear space portions formed in the article support 50, and the inner surface side of the side bracket 61 is brought into contact with the end face side of the article support 50. A bolt body 69 passed from the outside through the hole 64 is screwed and coupled to one 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 portion 67, the rotating body 70, and the side roller 71 are set on the side bracket 61 side. That is, the cylindrical connecting portion 67 is inserted into the cylindrical body 65 from the outside, and the flange portion 67A is positioned in contact with the outer end surface of the cylindrical body 65, and the outside of the tongue piece portion 67B group is positioned. By elastically engaging the direction convex portion 67D with the annular groove 65A, the connecting portion 67 can be connected to the cylindrical body 65 with an internal fit, and thus the cylindrical connecting portion 67 is provided on the side bracket 61 side. Can be set. Then, the rotating body 70 is externally fitted to the cylindrical body 65, and the side roller 71 is attached to the protruding piece 62A via the vertical axis 72 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 portion 67, so that 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. 1, by moving a predetermined portion of the endless chain 40 to the outside (bending), the predetermined portion is moved outward through the upright portion 11, and thus 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 insertion hole 68 of the cylindrical connection part 67 oppose each other, the protrusion part of the long connection pin 43 is inserted into the insertion hole 68 from the outside, and the tongue piece part The long connecting pin 43 can be coupled to the side bracket 61 by elastically engaging the inward convex portion 67C of the 67B group with the outward concave portion 44.

  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. In addition, the outside connection (release of connection) of the long connection pin 43 can be easily and quickly performed with improved workability without being disturbed by the upright 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. At that time, the fitting portion 66 of the side bracket 61 is externally fitted to the cylindrical body 65 in the adjacent side bracket 61.

  Next, the cover body 140 is disposed on the upper ends of the upper frame members 10. That is, the lower standing plate portion 141A is brought into contact with the standing portion 11 from the outside, and the lower end of the lower standing plate portion 141A is brought into contact with the receiving surface 11a from above, and the lower standing plate portion 141A is brought into contact with the lower end portion of the lower standing plate portion 141A. The bolt body 145 passed from the outside can be detachably fixed to the upright portion 11 of the upper frame member 10 by screwing the bolt body 145 into the nut body 146 previously positioned in the outward groove portion 14.

  At that time, the uppermost surface 142a of the horizontal plate portion 142A in the upper plate portion 142 may be at a level that is flush with the upper surface 54a of the article placement plate portion 54 and slightly lower than the flat surface 52a. The inclined upper surface 142b of the end inclined portion 142B can be a lower position that is lowered with respect to the upper surface 54a of the article placing plate portion 54. And this positional relationship can always be maintained constant by abutting the lower end of the lower upright plate portion 141A on the receiving surface 11a from above.

  Before and after the attachment of the article support 50 and the cover 140, the forward guide device 110, the backward guide device 116, the upper switching means 130, the lower switching means 131, and the sorting means are provided on the main body frame 1 side. 132A, 132B, etc. are provided. Thereby, the conversion equipment can be assembled.

  The conversion equipment assembled in this way can move 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. The movement of both endless chains 40 causes the article support 50 group to be supported and guided to the upper support surfaces 18a and 26a of the both guide rail portions 18 and 26 via the rotating body 70, and to both guide rails via the side rollers 71. It can move in a stable state by being guided by the lateral guide surfaces 18b and 29a of the portions 18 and 26. 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 such conveyance is performed, the article laterally pressing body 80 that moves integrally with the article support 50 group moves the guided portion 96 by guiding the guide roller 108 to the guide device groups 110 and 116. 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 108 guided to the start guide part 111A on one side is guided in a straight line when the sorting unit 132A is in the linear sorting position, and then advances straight in a state where it does not receive a guide action, and then the end guide part 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 108 of the start end guide portion 111B moves from the sorting means 132B to the end guide portion 114B.

  Further, the guide roller 108 guided to the one-side starting end guide portion 111A is inclined and guided inward when the distribution means 132A is in the inclined distribution posture, and is guided and moved inward by the inward movement guide portion 112A. After that, it moves to the outer movement guide part 113B via the upper switching means 130, is guided by this outer movement guide part 113B, is moved outward, and is 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 108 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 108 that has reached the end portions of the end guide portions 114A and 114B is guided by the reversal guide bodies 136A and 136B to be reversed. The return path guide device 116 is first guided by the inward movement guide portions 117A and 117B and 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.

  During such reversal, the front and rear side brackets 61 are relatively expanded and contracted, whereby the fitting portion 66 and the ring body 75 are slidably moved. 66 and the resin ring body 75, that is, sliding contact made of a material having a different fitting surface, for example, wear and noise compared to sliding contact made of the same material for the fitting surface. The occurrence of can be reduced.

  As described above, when the article lateral pusher 80 is moved, when the article lateral pusher 80 is in a no-load state without performing the lateral push movement or in a light load state in which the light article 160 is laterally pushed and moved, both upwards The abutting portion 101a of the tongue piece body 101 abuts on the flat surface 53a of the convex portion 53 from below, and the lower guided surfaces 96b and 97b are pressed against the lower guide surfaces 59b and 60b by the pressing force due to the elastic repulsive force. The contact portions 103a of both forward tongue pieces 103 abut against the front and rear guide surfaces 59a of the guide portion 59 from the inside, and the front and rear guided surfaces 97a are pressed against the front and rear guide surfaces 60a of the guide portion 60 by the back pushing force due to the elastic repulsion force. It will be.

  Thereby, in the reciprocating movement of the article laterally pressing body 80 in the longitudinal direction 51 of the article support 50, the contact portion 101a is in elastic contact with the flat surface 53a and is in sliding contact, and the lower guided surfaces 96b and 97b are lower. The abutting portion 103a is elastically abutted against and slidably contacted with the front and rear guide surfaces 59a, and the front and rear guided surface 97a is abutted against and slidably contacted with the front and back guide surfaces 60a. .

  Further, when the article lateral pusher 80 is in a heavy load state in which the heavy article 160 is laterally moved, the article lateral pusher 80 is slightly displaced with respect to the article support 50 by the lateral push bias load. That is, on the contact side with the article 160, the guided portions 96 and 97 rise against the elastic force of the upward tongue piece 101, and the upper guided surfaces 96 c and 97 c are flat surfaces 53 a of the convex portion 53. The front and rear guided surfaces 96a abut against the front and rear guide surfaces 59a from the inner side against the elastic force of the forward tongue piece 103 on the side opposite to the side in contact with the article 160. Become.

  As a result, the reciprocating movement of the article laterally pressing body 80 in the longitudinal direction 51 of the article support 50 causes the upper guided surfaces 96c and 97c and the contact portion 101a to come into sliding contact with the flat surface 53a, and the lower guided surface. 96b and 97b are in contact with the lower guide surfaces 59b and 60b to be in sliding contact, the front and rear guided surfaces 96a and the contact portion 103a are in contact with and in sliding contact with the front and rear guide surfaces 59a, and the front and rear guided surfaces 97a are in contact with the front and rear guide surfaces 60a. This can be done in a state of abutting and sliding.

  Accordingly, the reciprocating movement of the article laterally pressing body 80 is guided and fitted to the guide portions 59 and 60 of the article support 50 through the front and rear guided portions 96 and 97, that is, suitable. In a state where sliding friction is generated, there is no backlash and the posture (orientation) is not greatly changed, and it can always be performed stably. Further, the group of tongue pieces 101 and 103 are formed so as to be distributed to both ends in the length direction 51, so that the movement of the article laterally pressing body 80 causes the same suitable sliding friction in both reciprocation. It can be done in the state.

  In addition, a downward convex portion 53 is formed on the lower surface of the article placing plate portion 54, a lower portion of the convex portion 53 is formed on the flat surface 53a, and upper surfaces of the guided portions 96 and 97 are formed on the flat surface. By forming the upper guided surfaces 96c and 97c facing the lower side of 53a, the upper guided surfaces 96c and 97c move on the flat surface 53a when the article laterally pressing body 80 group moves in the length direction 51. Since the sliding is performed, the movement can be performed in a state where the frictional resistance is small, so that the intended movement can be smoothly performed without damaging the article laterally pressing body 80 and without wearing the article support 50 side.

  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. At this time, the article 160 is supported between the flat surfaces 52a of the convex portion 52 group and slides on the flat surfaces 52a. Therefore, the desired branching movement can be performed smoothly without damaging the article 160 and without wearing the article support 50 side.

  The side portion of the lateral pushing action portion 85 is laterally abutted in a state where the left and right corners of the front end portion 81A are formed on the arc-shaped side surface 81b, and the laterally pushing contact surface 90a continues to the rear end of the arc-shaped side surface 81b. Since the member 90 is provided, almost the entire length of the side portion of the lateral pushing action portion 85 can be used as the lateral pushing action surface, so that stable lateral pushing movement can be achieved, and the front and rear article side pushing bodies 80 can be provided. The gap S (see FIG. 5) between the side pushing action portions 85 at the side can be reduced to enable the intended side pushing movement in a state where the article 160 does not enter.

  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, and is connected to the inclined upper surface 86a at the front end part with respect to the inclined upper surface 86a. 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.

  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. At this time, the article 160 on the article support 50 is placed above the cover 140 fixed to the upper frame member 10 so that the upper part of the endless chain 40 is closed. By climbing over, it is possible to prevent dust or the like adhering to the article 160 from falling to the endless chain 40 side.

  At this time, the uppermost surface 142a of the cover body 140 is positioned at the same level as the upper surface 54a of the article support 50, and the branch conveyance surfaces 150a and 150b of the branch paths 150A and 150B are placed on the same plane as the uppermost surface 142a. By being positioned at a single level, the article 160 from the article support 50 side can smoothly branch and move from the top surface 142a to the branch conveyance surfaces 150a and 150b without rattling up and down. Thus, damage to the article 160 and generation of noise can be prevented.

Furthermore, by forming the inner end portion of the cover body 140 on the inclined upper surface 142b that descends with respect to the upper surface 54a, for example, the article 160 itself is soft or the package body of the article 160 is soft. Even if it is in contact with the hanger 54a, when it moves from the upper surface 54a to the uppermost surface 142a at the time of branching movement, it is first received by the inclined upper surface 142b and guided to the uppermost surface 142a side. The cover body 140 can be reliably branched and moved without entering under the cover body 140.

In addition, since the concave portion 144 is formed on the inner surface side of the corner portion 143 formed by the side plate portion 141 and the upper plate portion 142 of the cover body 140, the article 160 from the article support body 50 side contacts the uppermost surface 142a. When there is a large impact, the upper plate portion 142 is bent through the recess 144, so that the impact can be buffered.
