In the hanging device of the present embodiment, the hanging rod 4 is inserted into the hanging position B by the hanging rod moving body 5, and the suspension rod 4 is smoothly moved out after the hanging rod, thereby shortening the stop time of the conveyor. Since it is the main purpose, it is preferable that the hanging position B is near the curved portions on both sides of the conveyor 2, and the supply / discharge position A is on the side of the carrying position B and does not conflict with the conveyor 2. Is preferable.

First, the hook 1 will be described with reference to FIGS. 3 and 4 (a) and 4 (b). The hook 1 divides one plate-shaped hook body into upper and lower parts, and has a base end portion 11 connected to the conveyor 2 and a tip portion (hanging portion 12c) for hanging toward the tip end direction. It has a part 12. A plate-shaped auxiliary connecting portion 13 fixed by a screw is provided on the side surface of the base end portion 11, and a rotating shaft 14 is inserted into a shaft hole 15 below the auxiliary connecting portion 13. A pinion 16 serving as a drive transmission portion is arranged on the base end side, which is one end of the rotating shaft 14, and is fixed to the side surface of the tip portion 12 on the tip end side, which is the other end.

The hook 1 is obtained by dividing the base end portion 11 and the tip end portion 12, but can be molded with the base end portion 11 and the tip end portion 12 divided from the beginning, or even if a ready-made hook is cut. good. As will be described later, since the tip portion 12 is rotated by the rotation shaft 14, a predetermined gap 17 is provided between the base end portion 11 and the tip portion 12 so that the thickness of the tip portion 12 does not come into contact during this rotation. Has.

The base end portion 11 is formed with hook-shaped conveyor connecting portions 11a and 11a for connecting to the conveyor 2 (see FIGS. 1 and 2) at the upper portion. In the present embodiment, the hook-shaped body is formed at two upper and lower positions, but there may be only one place or a connecting means other than the hook-shaped body. The base end portion 11 is formed with an extension portion 11c that inclines downward from the connection portion 11b having the conveyor connection portions 11a and 11a toward the tip end portion 12 and extends forward.

The tip portion 12 is formed with an extension portion 12a that inclines downward and extends forward and forward like the extension portion 11c of the base end portion 11, and a burrs portion 12b that jumps up laterally and forward from the tip of the extension portion. Between the extension portion 12a and the burrs portion 12b, a hooking portion 12c is formed which is a portion cut out so as to be curved downward in a front view (see FIG. 4A). The sausage-like substance 3 can be hung on the hanging portion 12c. The form of the tip portion 12 is not necessarily limited to the present embodiment, and may be a hook shape in which the sausage-like object 3 can be hung with an open upper portion.

A cylindrical pinion 16 having an unevenness at one end of the rotating shaft 14 is arranged, and is rotated by a rack 41 (see FIG. 9) described later to transmit the rotational power to rotate the tip portion 12. The rotating shaft 14 is inserted into a shaft hole 15 opened below the auxiliary connecting portion 13, and the shaft hole 15 serves as a shaft center. In the front view shown in FIGS. 4A and 4B of the present embodiment, the shaft hole 15 is in the vicinity of the hooked portion 12c of the tip portion 12, and specifically, is closer to the curved surface of the hooked portion 12c. It is located below. That is, by locating the axis that rotates slightly below the sausage-like object 3 suspended from the hanging portion 12c, the hanging portion 12c is rotated around the sausage-like object 3 so that the hanging portion 12c can be stably hung. I have to.

The rotating shaft 14 is provided with a step portion 14a that is bent upward between the shaft hole 15 and the tip portion 12 and further bent in the direction of the tip portion, and is further extended and fixed to the upper side surface of the tip portion 12. ing. The fixing position with the tip portion 12 is the upper edge of the side surface of the tip portion 12, and is fixed to the side surface in the direction opposite to the direction in which the tip portion 12 is rotated. As a result, the hooking portion 12c is rotated about the center, and the tip portion 12 is rotated so as to push down from above, so that the rotation can be stably performed even if the power for rotation is reduced.

The stepped portion 14a of the rotating shaft 14 of the present embodiment is in a two-step bent form, but is not necessarily limited to this, and may be curved in a substantially S shape or the like. Further, the fixing means with the tip portion 12 may not be fixed to the side surface but may be connected to the surface on the rotating shaft side.

Further, as shown in FIG. 3, in the hook 1 of the present embodiment, an elastic body 14b having an urging force is arranged so as to maintain a non-rotating state, and when the pinion 16 is suddenly rotated, the tip portion 12 is placed. I try not to rotate it. Further, as shown in FIG. 4, a plunger 19 is arranged on the pinion 16, and a plunger pin 19 that can be retracted so as not to rotate unless a strong driving force is applied by the rack 41 is inserted into the rotation shaft 4. , The unexpected rotation of the pinion 16 is suppressed. Further, the guide plate 18 is arranged so that when the tip portion 12 returns from the rotating state to the non-rotating state, the tip portion 12 does not return too much.

Next, the hanging rod moving body 5 and the parallel running portion 6 will be described with reference to FIGS. 5 to 8. As described above, the hanging rod moving body 5 moves the hanging rod 4 so as to insert and exit the supply / discharge position A and the hanging position B, and the parallel running portion 6 is related to the pinion 16. The matching rack 41 is run in parallel with the hanging rod 4. The hanging rod moving body 5 has the same longitudinal direction as the hanging rod 4, and the rod holding portion 32 and the rod receiving portion 33 extend in the loop direction from both ends thereof.

The hanging rod moving body 5 inserts the hanging rod 4 into the loop of the sausage-like object 3 and causes it to exit after being hung, but the hanging rod moving body 5 itself is outside the loop of the sausage-like object 3. To position. The moving position of the hanging rod moving body 5 outside the loop in the present embodiment is below the hook 1 suspended from the transport conveyor 2 and to the side of the loop of the sausage-like object 3 on the conveyor side. That is, the hanging rod moving body 5 moves in the same direction as the direct delivery direction of the conveyor, and moves below the base end portion 11 in the side view of the continuous hook 1. The hanging rod moving body 5 has a rod holding portion 32 arranged on the side thereof at one end in the longitudinal direction via an arm, and the rod holding portion 32 holds one end of the hanging rod 4. Further, a rod receiving portion 33 is arranged at the other end in the longitudinal direction via an arm, and the other end of the hanging rod 4 is supported from below by the rod receiving portion 33. With this configuration, the hanging rod moving body 5 located below the base end portion 11 of the hook 1 outside the loop inserts only the hanging rod 4 into the loop of the sausage-like object 3 suspended from the tip end portion 12. Can be held as possible. In this way, the hanging rod moving body 5 is moved outside the loop, and only the hanging rod 4 is inserted into and exits from the loop, so that the movement of the hanging rod 4 is speedy and there are few mistakes. Can be done. Further, in the present embodiment, the rod holding portion 32 and the receiving portion 33 are also located on the front side and the rear side in the longitudinal direction of the loop and are located outside the loop, and only the hanging rod 4 is inserted into the loop. It is supposed to be.

As shown in FIG. 6, the rod holding portion 32 projects from the side of the hanging rod moving body 5 to hold the end portion of the hanging rod 4 on the supply / discharge position A side, and is a receiver that supports from below. It is composed of a portion 32a and a chuck 32b that is gripped from above, and can firmly hold the end portion of the hanging rod 4. Further, as shown in FIG. 7, the rod receiving portion 33 has a receiving portion 33a that supports from below, and the receiving portion 33a rotates downward and is accommodated under the hanging rod moving body 5. It has a swivel cylinder 33b, which is a release mechanism for releasing the support of the hanging rod 4. With this configuration, the swivel cylinder 33b, which is a release mechanism, is operated to release the support of the rod receiving portion 33, and the hanging rod 4 can be held in a cantilever state only by the rod holding portion 32, and the rod receiving portion 33 can be held. It is possible to change the state of holding both sides as appropriate.

As shown in FIG. 5, the hanging rod moving body 5 can reciprocate between the hanging position B and the supply / discharging position A on the arranged rails 31 and 31 (see FIG. 8). This travel is controlled by a control means (not shown). The hanging rod moving body 5 is provided with front and rear cylinders 34 that extend forward and backward so as to project the rod holding portion 32 and the rod receiving portion 33, and the rod holding portion 32 and the rod receiving portion 33 as described later. Can be moved so as to extend the arm further toward the side of the hanging rod moving body 5.

As shown in FIG. 7, in the hanging rod moving body 5, the parallel running portion 6 runs in parallel, and a rack 41 having continuous unevenness is arranged on the upper portion of the parallel running portion 6. The parallel running portion 6 is located further back than the hanging rod moving body 5 (the side opposite to the hook 1) so that the rack 41 moves below the pinion 16 in the side view of the hook (the rack 41 moves below the pinion 16). (See FIG. 3). The hanging rod moving body 5 causes the parallel running portion 6, the rod holding portion 32, and the hanging rod 4 held by the rod receiving portion 33 to move in parallel so as to move at the same time.

As shown in FIGS. 7 and 8, the rack 41 has a length substantially equal to the longitudinal length of the hanging rod 4, and can engage with the unevenness of the pinion 16 of the hook 1 on the upper surface of the rack 41. Unevenness is formed. The rack 41 is moved to a lower position slightly away from the pinion 16 of the hook 1 so as not to unexpectedly engage with the pinion 16 during traveling.

The rack 41 is raised and lowered by the rack raising and lowering cylinder 42. It is located below the pinion 16 of the hook 1 in a state of traveling from the supply / discharge position A to the hanging position B by the hanging rod moving body 5. In this state, it is raised by the rack elevating cylinder 42 and meshes with the unevenness of the rack 41 and the unevenness of the pinion 16 of the hook 1 so as to engage with each other. With the rack 41 and the pinion 16 in mesh with each other, the rack 41 is slightly moved upstream (filling machine 9 side) to rotate the pinion 16, and the rotational power is transmitted to the tip 12 of the hook 1 to hook the hook. The tip portion 12 of 1 rotates as shown in FIG. 4 (b). Since the length of the rack 41 in the longitudinal direction extends from the hook 1 on the downstream side of the hook group 1a to the hook 1 on the upstream side, all the pinions 16 and 16 of the hook group 1a can be rotated together. become.

The movement of the hanging rod 4 by the hanging rod moving body 5 will be described. The rod receiving portion 33 is supported from below by the receiving portion 33a having a recess, but when the receiving portion 33a is swiveled downward by the swivel cylinder 33b which is a release mechanism to release the support, the hanging rod 4 holds the rod. Only the part 32 is in a cantilever state. When the hanging rod 4 held by the hanging rod moving body 5 outside the loop is inserted into the loop of the sausage-like object 3, if both ends of the hanging rod 4 are held, the holding portion comes into contact with the loop. Will end up. Therefore, it is necessary to release the support of the rod receiving portion 33, which is the support on the insertion side of the hanging rod 4, so that the hanging rod 4 can be cantilevered. By setting this cantilever state, the hanging rod 4 can be inserted into the loop without the hanging rod moving body 5 coming into contact with the moving body 5.

When the tip portion 12 of the hook 1 is rotated by the rack 41 at the hanging position B, the sausage-like object 3 falls on the hanging rod 4, and the sausage-like object can be hung from the hook 1 to the hanging rod 4. .. At this time, before the tip portion 12 is rotated before being hung, the receiving portion 33a of the rod receiving portion 33 is swiveled upward by the swivel cylinder 33b to support both ends of the hanging rod 4. It is possible to smoothly hang the object 3 without falling off from the hanging rod 4 in the hung state. That is, the support by the rod receiving portion 33 is released and the cantilever state is set only when the hanging rod 4 is inserted into the loop, and other than that time, when the sausage-like object 3 is hung or described later. When the hanging rod 4 is supplied and discharged, it is in a double-sided state.

Further, by causing the hanging rod moving body 5 to run the rack 41, the rod holding portion 32, and the rod receiving portion 33 in parallel, positioning at the hanging position B becomes easy, and the operating hook 1 and the hanging rod 4 are operated. By determining both ends of the above, there is also the effect of significantly reducing operational mistakes.

Next, a supply / discharge device 7 for supplying and discharging the hanging rod 4 to the hanging rod moving body 5 will be described with reference to FIGS. 9 to 16. As described above, the supply / discharge device 7 is arranged in the vicinity (side) of the supply / discharge position A, which is on the downstream side of the curved portions (both ends of the direct delivery portion) of the conveyor 2 (see FIG. 2). As shown in FIG. 9, the supply / discharge device 7 is installed on the downstream side and side of the conveyor 2, and has a supply unit 50 for supplying the hanging rod 4 in the lower stage and a sausage-like material 3 in the upper stage. It has a two-stage configuration with a discharge unit 60 that discharges the suspended hanging rod 4, and lifters 70 are arranged on the sides of these.

The supply unit 50 holds both ends of the hanging rod 4 by two flat plate-shaped receiving plates 51, which will be described as one receiving plate 51 and a transfer plate 52 for the sake of description of the drawings. As shown in FIG. 10, both of the receiving plates 51 are formed with the receiving plate recesses 51a and 51a recessed downward from the upper edge at the same predetermined pitch, and are formed in the receiving plate recesses 51a and 51a of the pair of receiving plates 51. The hanging rod 4 can be engaged and supported and held from below.

The transfer plate 52 is used as a means for sending the hanging rod 4 held in the receiving plate recesses 51a and 51a formed at a predetermined pitch to the supply side (transferring to the receiving plate recesses 51a and 51a at the next pitch destination). To place. The transfer plate 52 is a pair of plate-like bodies like the receiving plates 51 and 51, and is recessed from the upper edges of the transfer recesses 52a and 52a at the same pitch as the receiving plate recesses 51a and 51a. The transfer plates 52 are lined up on the outside of the receiving plates 51 so as to be in contact with the receiving plates 51 and 51, and are slightly below the receiving plates 51 during normal times when they are not in operation.

Further, the transfer plate 52 of the supply unit 50 is provided with an elevating cylinder 53 so as to be movable in the vertical direction with respect to the receiving plates 51 and 51, and the front and rear cylinders 54 are also arranged so that the receiving plates 51 and 51 can be moved. It is possible to move in the front-back direction. In the present embodiment, the elevating cylinder 53 and the front-rear cylinder 54 that transfer the transfer plate 52 back and forth and up and down are used as the transfer mechanism.

A lifter 70 in the vertical direction is arranged on the supply side (front side) of the supply unit 50. The lifter 70 has a pair of upper and lower gears 71 and a chain 72 that spans the gears 71. A pair of lifter recesses 73 are arranged in the lifter 70 so as to be able to move up and down. Like the receiving plate recess 51a and the transfer recess 52a, the lifter recess 73 has a portion recessed from the upper edge so that the end portion of the hanging rod 4 can be held.

The lifter recess 73 of the lifter 70 has the same length as the pitch between the receiving plate recesses 51a and 51a of the receiving plate 51, and is located further from the position on the supply side (front side) to the supply side (front side). Therefore, when the transfer plate 52 transfers the hanging rods 4 held by the receiving plate recesses 51a and 51a on the supply side of the hanging rods 4 held by the receiving plate 51, they are held by the lifter recesses 73. It will be.

The transfer of the hanging rod 4 of the supply unit 50 will be described with reference to FIGS. 11 and 12. As shown in FIG. 11A, the hanging rod 4 is held in the receiving plate recesses 51a and 51a of the receiving plate 51. From this state, as shown in FIG. 11B, only the transfer plate 52 is moved up and down by the elevating cylinder 53, so that the transfer recesses 52a and 52a of the transfer plate 52 support the hanging rod 4. The engagement with the receiving plate recesses 51a and 51a is released and the rod stands up. Then, as shown in FIG. 12A, the transfer plate 52 is advanced by the front-rear cylinder 54 to the next receiving plate recesses 51a and 51a on the supply side (front side) and overhangs. Then, as shown in FIG. 12B, the elevating cylinder 53 further lowers the vehicle. By this operation, the hanging rod 4 held in the transfer recesses 52a and 52a of the transfer plate 52 is transferred to the next receiving plate recesses 51a and 51a on the supply side of the receiving plate 51. The transfer plate 52 advances to the supply side to transfer the hanging rod to the next receiving plate recesses 51a and 51a, and then further lowers by the elevating cylinder 53 to hold the hanging rod 4 only by the receiving plate 51. Then, it is retracted by the front and rear cylinders 54 and returned to the initial position. Due to the above supply, the hanging rod 4 that was closest to the supply side (front side) in the state shown in FIG. 11A is delivered to the lifter recess 73 of the lifter 70 by transfer by the transfer plate 52.

The lifter 70 can push up the lifter recess 73 in the vertical direction, and can lower the lifter recess 73 from the pushed up state. As shown in FIG. 16, when the hanging rod 4 is supplied to the lifter recess 73, the lifter 70 pushes the lifter recess 73 above the discharge portion 60 (arrow line Z). In this state, by moving the rod holding portion and the rod receiving portion 33 of the hanging rod moving body 5 to the discharge side and moving them to the delivery position (arrow line Y), the rod holding portion and the rod receiving portion 33 are moved below the lifter recess 73 located above. The rod holding portion 32 and the rod receiving portion 33 are positioned. By further operating the lifter 70 in this state and lowering the lifter recess 73, only the hanging rod 4 can be delivered and supplied to the rod holding portion 32 and the rod receiving portion 33.

In the longitudinal direction of the hanging rod 4, the rod holding portion 32 and the rod receiving portion 33 are located inside the lifter recesses 73 and 73, respectively, so that they do not come into contact with each other. Therefore, the hanging rod 4 can be delivered to the rod holding portion 32 and the rod receiving portion 33 by the vertical movement of the lifter recesses 73 and 73. The rod holding portion 32 holds the hanging rod 4 by chuck-type engagement holding, but at the time of this delivery, the chuck holding is released, and only the receiving member 32a holds the hanging rod 4 by receiving from below.

The supply unit 50 and the lifter 70 of the present embodiment are not necessarily limited to the present embodiment. For example, the lifter 70 may be raised and lowered by a cylinder, and the supply unit 50 may also be in the shape of a rail having a predetermined thickness.

Next, the discharge unit 60 will be described. As shown in FIGS. 9 and 13, in the discharge unit 60, similarly to the supply unit 50, a plurality of plate-shaped receiving plate recesses 61a and 61a are arranged at appropriate pitches on a pair of flat plate-shaped receiving plates 61. Further, a transfer plate 62 is provided side by side, and a plurality of transfer recesses 62a and 62a are arranged on the transfer plate 62 at the same pitch. It is the same as the supply unit 50 that the transfer plate 62 moves up and down by the elevating cylinder 63 (transfer mechanism) and moves back and forth by the front-rear cylinder 64 (transfer mechanism). The pitch interval is also the same as that of the supply unit 50 and the discharge unit 60.

Since the discharge unit 60 discharges the hanging rod 4, the transfer by the transfer plate 62 is in the opposite direction to the supply unit 50. In the supply unit 50, the transfer plate 52 lifts the hanging rod 4 and transfers it to the next pitch, but in the discharge unit 60, the transfer plate 62 is lowered by the elevating cylinder 63 and engaged with the receiving plate recesses 61a and 61a. The engagement with the held hanging rod 4 is released. Then, the front and rear cylinders 64 move to the supply side. Further, since the rod holding portion 32 and the rod receiving portion 33 of the hanging rod moving body 5 are projected and moved to the discharge side by the front-rear cylinder 54 so that the arm extends, the receiving plate recesses 61a and 61a of the discharge portion 60 The rod holding portion 32 and the rod receiving portion 33 are located at positions having the same pitch from the most front position of the rod. This position is the delivery position (see FIG. 16).

As shown in FIG. 14 (b), the transfer plates 62, 62 are moved from the state shown in FIG. 14 (a) to the front supply side. Then, as shown in FIG. 15A, when the rod is raised by the elevating cylinder 63, the support of the hanging rod 4 supported from below by the rod holding portion 32 and the rod receiving portion 33 is released, and the transfer plate 62 is lifted. It can be delivered to the transfer recess 62a. Then, as shown in FIG. 15B, the front and rear cylinders 64 retract the receiving plate 61 to the upper side of the receiving plate recesses 61a and 61a. Then, the transfer plates 62 and 62 are pushed down by the elevating cylinder 63 until they are arranged side by side with the receiving plates 61 and 61. By this operation, the hanging rod 4 is discharged from the rod holding portion 32 and the rod receiving portion 33 of the hanging rod moving body 5, and the hanging rod 4 discharged before the discharge is also gradually transferred in the discharge direction. can do.

Supply stock and discharge stock are arranged in the supply unit 50 and the discharge unit 60 from the terminal positions (end positions on the discharge side) of the receiving plates 51, 51, 61, 61 (not shown). The supply stock has a rail shape that inclines upward from the terminal positions of the receiving plates 51 and 51 of the supply unit 50, and the hanging rod 4 before supply is stocked in the stock. When the receiving plate recesses 51a and 51a are sequentially transferred by the receiving plates 51 and 51 and the transfer plates 52 and 52, the hanging rod 4 that has slid down from the inclination is supplied to the receiving plate recesses 51a and 51a located on the most discharge side. I am trying to do it.

Further, the discharge stock has a rail shape that inclines downward from the end position of the discharge unit 60, and is automatically discharged when it is located in the receiving plate recesses 61a, 61a at the position on the most discharge side of the discharge unit 60. The slope of the stock 65 is slid down. In order to smoothly perform this, the end side of the recesses 61a and 61a of the receiving plate recesses 61a and 61a at the position on the most discharge side of the discharge unit 60 is cut off to the discharge stock side, and the discharge stock is discharged when the transfer plates 62 and 62 move. I try to slide down. In this case, the edge of the receiving plate recess 61a on the terminal side comes into contact with the hanging rod 4 so as to slightly poke it, and the hanging rod 4 is rolled and led to the discharge stock. Since it has a horizontal stock position after the discharge stock is tilted, the hanging rod 4 can be taken out at that stock position.

Next, the flow of the operation of supplying, discharging, and delivering the hanging rod 4 to the sausage-like object 3 according to the present invention will be described.

First, the hanging rod moving step will be described. The sausage-like substances 3 filled by the filling machine 9 are suspended from the hook group 1a and conveyed to the conveyor 2 at appropriate intervals. When the transfer conveyor 2 is in the transfer state, the filling machine 9 sequentially performs the filling operation. The hanging rod 4 is inserted into the loop of the sausage-like object 3 by the hanging rod moving body 5 while the sausage-like object 3 is in the transporting operation state to reach the hanging position B. At this time, before the insertion, the support by the receiving portion 33a of the rod receiving portion 33 that holds the hanging rod 4 is released, and only the rod holding portion 32 is inserted as a cantilever state. In the hanging step after the insertion is completed, the rod receiving portion 33 is restarted and supported by the receiving portion 33a (in a double-sided state).

Next, the crossing step will be described. The hanging rod 4 is inserted into the loop of the sausage-like object 3, and when the transfer by the transfer conveyor 2 reaches the hanging position B, the transfer of the transfer conveyor 2 is stopped. At this time, filling by the filling machine 9 is also stopped. Then, the rack 41 running in parallel with the hanging rod 4 is raised, and the rack 41 and the pinions 16 and 16 of the hooks 1 and 1 of the hook group 1a are engaged with each other. Then, the rack 41 is further moved slightly upstream, the pinions 16 and 16 are rotated, the tip portion 12 of the hook 1 is rotated, and a sausage-like object suspended on the hook portion 12c of the tip portion 12. By dropping 3 onto the hanging rod 4, the sausage-like object 3 is hung from the hooks 1 and 1 to the hanging rod 4.

Next, the step of leaving the hanging rod will be described. When the hanging of the sausage-like material 3 to the hanging rod 4 is completed, the transport stopped state of the transport conveyor 2 is released and the transport is restarted (filling by the filling machine is also restarted). Then, the hanging rod 4 that has been hung is restarted to convey the conveyor so as not to conflict with the sausage-like object 3 hung on the next hook group 1a located behind the hung hook group 1a. Exit toward the supply / discharge position A at the same time or in close proximity.

In addition, the supply / discharge step will be described. The supply / discharge device 7 of the hanging rod 4 supplies / discharges the hanging rod 4 in conjunction with the above-mentioned delivery. First, the hanging rods 4 and 4 appropriately arranged in the supply unit 50 supply the suspension rod 4 to the lift rod holding unit 73 by the operation of the above-mentioned supply unit. The supplied lift rod holding portion 73 is raised by the operation of the lifter 70.

With the lift rod holding portion 73 raised and standing by, the hanging rod 4 to which the sausage-like object 3 has already been delivered moves to the front side of the supply / discharge device 7 by the hanging rod moving body 5. Then, the rod holding portion 32 and the rod receiving portion 33 project and move the hanging rod 4 on which the sausage-like object 3 is hung in front of the discharging portion 60 by the protruding moving mechanism, and suspend by the operation of the discharging portion 60 described above. Discharge the rod 4. Then, the lift rod holding portion 73 that has been standing by is lowered by the lifter 70, so that the suspended rod 4 to be supplied is delivered to the rod holding portion 32 and the rod receiving portion 33 that are protruding and moving. The hanging rod moving body 5 releases the protruding rod holding portion 32 and the rod receiving portion 33 to return to their original positions, and is further aligned with the rack 31 by the hanging rod moving body to the next hook group 1a. Run and move.

By the above method, it is possible to improve the efficiency of the hang-up operation by shortening the stop of the transfer of the transfer conveyor as much as possible. Since it is not necessary to stop the conveyor when the hanging rod 4 is inserted and when the rod 4 is removed, the conveyor 2 is stopped only when the hanging rod 4 is hung, so that the time saving effect of shortening the working time can be exhibited. Further, as for the hanging, since the hook is rotated and dropped, the quick hanging can be performed, so that a further time saving effect can be exhibited.
