It arrange | positions in the state made to fully approach the side-plate part of the body 259. FIG. Note that the upward dovetail groove 15 or the like of the upper frame member 10 may be used for connection with the branch conveyors 261A and 261B. Reference numeral 270 denotes an article.

Hereinafter, in the first embodiment described above, the conveyance and branching operations of the article 270 will be described.
That is, both endless chains 40 can be moved 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 moving the both endless chains 40, the article support 50 group is supported and guided to the upper support surfaces of the both guide rail portions 18 and 26 via the rotating body 64, and the guide rail portion 18 and the upper end are supported via the side rollers 65. It can move in a stable state by guiding it to the lateral guide surface of the extension portion 29. At this time, the upper end extension 29 is positioned above the rotating body 64 on the return path side, so that the rotating body 64 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 270 supplied on 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 259 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.

  The article laterally pressing body 70 that moves integrally with the article support 50 group during such transport is guided by the guide rollers 100 and 200 to guide the length of the article support 50. It reciprocates in the vertical direction 51, or moves linearly along the main transport path 45 together with the article support 50. At that time, the reciprocating movement of the article laterally pressing body 70 is in a state of being guided by being fitted to the guide portion 57 of the article support body 50 via the fitted portion 79, that is, suitable sliding contact friction is generated. In this state, there is no backlash and the posture (orientation) is not changed greatly, so that it can always be performed stably.

  For example, in the outward guide device 100, the guide roller 86 guided to the one-side starting end guide portion 101A is linearly guided when the distribution means 110A is in the linear distribution posture as shown in FIG. It will go straight without receiving. That is, the cylinder device 130 is contracted to swing the sorting guide body 120 inwardly around the longitudinal axis 126, and the shaft sorting surface 120e is moved with respect to the guide surface 105 and the shaft guide surface 111d of the straight traveling zone 105c. Position it in a straight line.

Then the guide roller 86, for example, as shown in (b) of FIG. 12, is greeted encased by aligning guiding the starting end zone portion 103a of the guide surface 103 of the guided body guiding portion 102. At this time, the roller shaft 85 is positioned in the introduction zone 105a. Next, the guide roller 86 is aligned and guided from the starting end zone portion 103a to the intermediate zone portion 103b. When the guide roller 86 moves, the roller shaft 85 moves as shown in FIG. The alignment is guided by the alignment zone 105b. That is, the roller shaft 85 is centered and guided by the support shaft guide portion 104 while the guide roller 86 is centeringly guided by the guided body guide portion 102.

  The roller shaft 85 is guided to alignment by the aligning zone 105b and then moved to the rectilinear zone 105c. As shown in FIG. 12C, the roller shaft 85 is maintained in the aligning state in the rectilinear zone 105c. Moved downstream. Therefore, since the roller shaft 85 coming out from the straight traveling zone portion 105c is in a centering state and there is almost no positional deviation in the left-right direction, the distribution guide body 120 of the distribution means 110A can be suitably disposed. As shown in 12 (d), it will pass through the shaft distribution surface 120 e of the distribution guide body 120 without contacting or colliding with it, or in a light sliding contact state, so that collision noise and wear can be almost eliminated.

  Then, the roller shaft 85 that has passed through the portion of the distribution guide body 120 is guided to the shaft guide surface 111d of the block body 111, and further, as shown by the imaginary line in FIG. The guide roller 86 is guided by the roller guide surface 115a, and thereafter, the guide roller 86 is moved straight without receiving a guide action. As a result, the article laterally pressing body 70 does not act on the article 270, and the article 270 is conveyed in a straight line on the main conveyance path 45. The same applies to the opposite side, and the guide roller 86 of the start end guide portion 101B goes straight in a state where it does not receive a guide action in the sorting means 110B.

  Further, as shown in FIG. 11, the guide roller 86 guided by the one-side starting end guide portion 101A is tilted inward when the distribution means 110A is in the inclined distribution posture, and is guided to the inner movement guide portion 107A. It will be guided and moved inward. That is, the cylinder device 130 is extended to swing the distribution guide body 120 outward about the longitudinal axis 126, and the guide surface 105 of the straight traveling zone 105c and the shaft guide surface 111e are connected by the shaft distribution surface 120f. Let

  Then, the roller shaft 85 is guided to be aligned by the alignment zone 105b in the same manner as described above, and then moved to the rectilinear zone 105c, and is moved downstream while maintaining the alignment state in the rectilinear zone 105c. . Therefore, since the roller shaft 85 that has come out of the straight traveling zone portion 105c is in a centering state, it is guided in a light slidable contact state without excessively colliding with the shaft distribution surface 120f of the distribution guide body 120. This can reduce impact noise and wear.

  Then, the roller shaft 85 that has passed through the portion of the distribution guide body 120 is guided to the shaft guide surface 111e of the block body 111, and further, as indicated by the imaginary line in FIG. After being guided by the roller guide surface 115b, the guide roller 86 is moved inward by being guided by the inner movement guide portion 107A, and then moved to the outer movement guide portion 108B via the upper switching device 150. Guided by the guide unit 108B and moved outward. As a result, the group of article laterally pressing bodies 70 traverses the main transport path 45 while moving in the transport direction, so that the lateral pushing action portion 76 is brought into contact with the article 270 via the laterally pushing contact member 78 on the other side. By laterally acting, the article 270 is branched and moved with respect to the main transport path 45 while changing its direction, and is transferred to the other branch conveyor 261B.

  The same applies to the opposite side, and the guide roller 86 of the start end guide portion 101B is guided by the sorting means 110B, the inner side movement guide portion 107B, the upper switching device 150, and the outer side movement guide portion 108A. The side pushing action portion 76 side-presses the article 270 via the one-side transverse pushing contact member 78, and passes the article 270 to one branch conveyor 261A.

  The guide roller 86 that has reached the end in this manner is guided by the reverse guide bodies 44A and 44B and reversed. In the return path guide device 200, the guide roller 86 is first guided by the inner guide surfaces 202A and 202B facing each other of the inner movement guide portions 201A and 201B and moved to the center portion. That is, the guide roller 86 is guided from the start end taper portion 203a to the intermediate taper portion 203b and moved to the center portion, and after being guided in alignment, is moved to the end parallel portion 203c. As shown in FIG. The parallel part 203c is moved downstream while maintaining the alignment state. Next, after the guide roller 86 is distributed to the left and right by the lower switching device 210, the guide roller 86 is guided to the outer guide surfaces 206A and 206B in the outer movement guide portions 205A and 205B and moved outward. After that, after being guided and reversed by the reversing guide bodies 43A and 43B, it is moved to one of the start end guide portions 101A and 101B.

  For example, as shown in FIG. 21, in the backward guide device 200, the guide roller 86 that is centered and guided by the terminal end parallel portion 203c is linearly guided when the distribution guide portion 221 is in the linear distribution posture, and performs a guide action. It will go straight without receiving. That is, the cylinder device 230 is contracted to swing the sorting guide body 222 inwardly around the longitudinal axis 226, and the shaft sorting surface 222e is moved with respect to the guide surface 215 and the shaft guide surface 252d of the straight travel zone 215b. Position it in a straight line.

  Then, the roller shaft 85 is positioned in the introduction zone portion 215a in the merging guide portion 211 immediately before the guide roller 86 that is aligned and guided by the end parallel portion 203c, just leaves the end parallel portion 203c. Next, the roller shaft 85 is guided to be aligned by the introduction zone portion 215a, and is moved downstream while maintaining the alignment state in the straight traveling zone portion 215b. Therefore, since the roller shaft 85 that has come out of the straight traveling zone portion 215b is in a centering state and there is almost no positional deviation in the left-right direction, the distribution guide body 222 of the distribution guide portion 221 can be suitably disposed. The collision guide body 222 does not collide or come into contact with the shaft distribution surface 222e, or passes through in a light sliding contact state, so that collision noise and wear can be almost eliminated.

  Then, the roller shaft 85 that has passed through the portion of the distribution guide body 222 is guided to the shaft guide surface 252d of the support shaft distribution guide portion 252c, and the guide roller 86 is guided by the guide body distribution guide as indicated by the phantom line in FIG. Guided by the roller guide surface 255a of the body 255, then the guide roller 86 is guided to the outer guide surface 206A in the outer movement guide portion 205A and moved outward. That is, the guide roller 86 is guided from the start end branching portion 207a to the intermediate inclined portion 207b and moved outward, and is guided to the end portion 207c and moved outward. After that, the guide roller 86 is guided by the reverse guide body 43A and reversed, and then moved to the start end guide portion 101A.

  Further, as shown in FIG. 22, the guide roller 86 that is centered and guided by the end parallel part 203c is tilted inward when the distribution guide part 221 is in the inclined distribution posture, and is guided to the outer movement guide part 205B. It will be guided and moved to the outside. That is, the cylinder device 230 is extended to swing the sorting guide body 222 outward around the longitudinal axis 226, and the guide surface 215 and the shaft guide surface 252e of the rectilinear zone 215b are moved by the shaft sorting surface 222f. Connect.

  Then, in the same manner as described above, the roller shaft 85 moved to the downstream side while maintaining the alignment state in the rectilinear zone portion 215b, and the roller shaft 85 coming out of the rectilinear zone portion 215b is in the alignment state. It will be guided in a light sliding contact state without colliding with the shaft distribution surface 222f of 222, so that collision noise and wear can be reduced.

  The roller shaft 85 that has passed through the portion of the distribution guide body 222 is guided to the shaft guide surface 252e of the support shaft distribution guide portion 252c, and the guide roller 86 is guided by the guided body distribution guide as indicated by the phantom line in FIG. Guided by the roller guide surface 255b of the body 255, the guide roller 86 is then guided to the outer guide surface 206B in the outer movement guide part 205B and moved outward. That is, the guide roller 86 is guided from the start end branching portion 207a to the intermediate inclined portion 207b and moved outward, and is guided to the end portion 207c and moved outward. Thereafter, the guide roller 86 is guided by the reverse guide body 43B and reversed, and then moved to the start end guide portion 101B.

  As described above, the guide roller 86 is inclined and guided inward by the distribution means 110A and 110B in the inclined distribution posture, and is guided and moved inward by the inner movement guide portions 107A and 107B, and then the upper switching device 150. To the outer movement guide sections 108B and 108A, and can be guided by the outer movement guide sections 108B and 108A, thereby moving the group of article laterally pressing bodies 70 across the main transport path 45 while moving in the transport direction. become. As a result, the lateral pushing action portion 76 is caused to laterally push the article 270, the article 270 is branched and moved, and distributed to the branch conveyors 261A and 261B.

  At that time, the switching operation of the upper switching device 150 can be automatically performed using the moving force of the roller shaft 85. That is, for example, when the guide roller 86 is guided by the inner movement guide portion 107A on one side and moved inward, and then moved to the outer movement guide portion 108B via the switching device 150, the switching device 150 is 15 and 16, the cam body 161 is swung to the other side (right side) around the upper support shaft axis 163, and the upper guide body 166 and the lower guide body 168 are The long link body 165 and the short link body 167 are swung to one side (left side) around the lower support shaft center 170 integrally.

  At this time, the side surface of the long link body 165 and the convex portion 167 c of the short link body 167 are in contact with the buffer member 178. Further, one (left side) upper guide surface 166a of the upper guide body 166 abuts on the stepped receiving surface 152e of the side portion forming member 152, so that the other (right side) upper guide surface 166a is on one side (abuts). The lower guide surface 168a of the lower guide body 168 is linearly connected to the upper guide surface 166a of the other (right side) of the upper guide body 166 in a straight line. And the lower guide surface 168a is linearly continued to the inclined surface 153a of the rear forming member 153.

  Therefore, the guide roller 86 from the inner side movement guide portion 107A on one side (left side) passes through the linearly continuous front inclined surface 152b, upper guide surface 166a, lower hand guide surface 168a, and inclined surface 153a. That is, it moves to the outward movement guide part 108B through the straight groove-shaped branch guide part 157B, and thus the group of article laterally pushing bodies 70 is traversed from the left side to the right side in the main transport path 45. At that time, as indicated by an imaginary line A in FIG. 16, the guide roller 86 that moves the cam body 161 is regulated and guided by the front inclined surface 152b and the regulating surface 158b, and the roller shaft 85 is It can pass without making it contact | abut to the cam surface 161a, and can maintain the attitude | position of the upper guide body 166 or the lower guide body 168.

  Further, when the guide roller 86 is switched so as to be guided to the other end (right side) start end guide portion 101B and guided from the sorting means 110B to the inward movement guide portion 107B by operating the lower switching device 210, as shown in FIG. Furthermore, when the rearmost guide roller 86 from the inner side movement guide part 107A on one side (left side) reaches the lower guide surface 168a of the lower side guide body 168, the inner side movement guide part 107B on the other side (right side). The frontmost guide roller 86 reaches the merging guide portion 156 and is in a position where the roller shaft 85 is brought close to (abuts) the cam surface 161a as shown by a solid line B in FIG.

  When the group of article supports 50 moves from this state, the roller shaft 85 comes into contact with the cam surface 161a, and the moving force of the roller shaft 85 pushes the cam body 161 to the opposite side (left side), as shown in FIG. Thus, the cam body 161 is swung to the left around the upper support shaft axis 163. At this time, the swing of the cam body 161 is transmitted to the long link body 165 via the arm portion 161b, the arm-like body 172, the rod-like body 174, the arm-like body 173, and the arm portion 165b. That is, the upper guide body 166 is swung to the right around the lower spindle axis 170. At that time, in the first half of the switching operation of the upper guide body 166, only the long link body 165 swings by a set length L obtained by subtracting the stopper section width 165w from the fitting section width 167w, and the short link body 167 is Since the upper guide body 166 is swung to the right side, the lower guide body 168 is not swung to the right side, so that the lower end guide body 168 guides the rearmost guide roller 86 without any trouble. It can be done smoothly.

  Then, when the article support 50 group further moves, the cam body 161 is continuously pushed to the opposite side (left side) by the moving force of the roller shaft 85, and as described above, the upper end of the article support 50 group is improved through the swing interlocking mechanism 171 and the like. The guide body 166 is swung further to the right around the lower support shaft axis 170. At this time, the set length L is absorbed (the long link body 165 swings by the set length L), and the stopper portion 165d is in contact with the convex portion 167c. Therefore, the upper guide body 166 is cut. In the latter half of the replacement operation, that is, thereafter, the long link body 165 and the short link body 167 are integrated and swung around the lower support shaft 170.

  Accordingly, as shown in FIG. 18, the other (right side) upper guide surface 166a of the upper guide body 166 abuts on the stepped receiving surface 152e of the side portion forming member 152, so that one (left side) upper guide surface 166a. Is continuous with the front inclined surface 152b on the other (abutting) side in a straight line, and one (left side) of the lower guide body 168 with respect to the upper guide surface 166a of one (left side) of the upper guide body 166 The lower guide surface 168a is continued in a straight line, and the lower guide surface 168a is continued in a straight line to the inclined surface 153a of the rear forming member 153.

  Accordingly, the foremost guide roller 86 from the inner side movement guide portion 107B on the other side (right side) has a linearly continuous front inclined surface 152b, upper guide surface 166a, lower guide surface 168a, and inclined surface 153a. Through the straight groove-shaped branch guide portion 157A and move to the outer movement guide portion 108A, thereby causing the group of article laterally pressing bodies 70 to cross from the right side to the left side in the main transport path 45. become.

  At this time, when the moving roller shaft 85 reaches the end portion of the cam surface 161a of the cam body 161, the guide roller 86 attached to the roller shaft 85 faces the upper guide surface 166a of the upper guide body 166. As a result, the guide roller 86 prevents the cam body 161 from rattling due to an impact when the roller shaft 85 is detached from the cam surface 161a and the upper guide body 166 is about to leave the step receiving surface 152e. As a result, the guide roller 86 can always be moved smoothly.

  As described above, the switching guide length in the upper switching device 150 can be sufficiently ensured by continuing the upper guide surface 166a of the upper guide body 166 and the lower guide surface 168a of the lower guide body 168, and the upper guide is provided. Switching between the body 166 and the lower guide body 168 can always be performed smoothly.
