Description

  The present invention relates to a transfer device for transferring a hanger member with a work to a take-out point after attaching a work to the hanger member at the work place, and more specifically, a first transfer path for transferring the hanger member to the work place, And a second transfer path for transferring the hanger member with the work from the work location to the removal location.

  This type of transfer device typically includes a pair of upper and lower transfer paths, attaches a work to a hanger member at a work site to form a hanger member with a work, and then conveys the hanger member with the work to an extraction site. At this time, the hanger member is transferred to the work location on the upper transfer path, and the hanger member with the work is transferred from the work location to the removal location on the lower transfer path. For example, in the device disclosed in Patent Literature 1, a transfer path having a substantially horizontal V-shape in a side view is provided between a work location and an extraction location. The upper transfer path is gradually inclined downward toward the work site, and the lower transfer path is gradually inclined downward as the work site is separated from the work site. Then, when the hanger member is set in the upper transfer path, the hanger member is transferred to the work site through the upper transfer path by its own weight. Therefore, at a work location, a work is attached to a hanger member to form a hanger member with a work, and the hanger member with a work is set in a lower transfer path. In this way, the hanger member with the work is transferred to the unloading point by its own weight through the lower transfer path.

  By the way, in a general transport device, since a work is attached to a hanger member manually, it is necessary to minimize the concentration of a plurality of hanger members at a work location. For this reason, the apparatus of the prior art is provided with a one-piece feeding device, a stopper device, and a sending-out device, and the hanger members can be sequentially arranged at the work site by these devices. That is, the hanger members are transferred one by one from the upper transfer path to the work site by the single feeder. Next, the hanger member is stopped at a work site by a stopper device, and a work is attached to the hanger member to form a hanger member with a work. Then, after the hanger member with the work is sent out to the lower transfer path by the feeding device, the next hanger member is transferred to the work site by the single feed device.

  By the way, in the device of the known art, from the viewpoint of workability and the like, a single feed device, a stopper device and a feed device are provided, and these devices are driven by individual actuators (electric components). For this reason, the configuration of the known technology tends to increase the number of components of the electrical components and complicate the configuration of the device, and is not a configuration that can be easily adopted from the viewpoint of power saving. The present invention has been made in view of the above points, and a problem to be solved by the present invention is to provide a transport device that contributes to power saving while improving workability.

  As means for solving the above problems, the transport device of the first invention includes a work place where a work is attached to a hanger member to form a hanger member with a work, an unloading place provided at a position different from the work place, It has a first transfer path for transferring the hanger member to the work site and a second transfer path for transferring the hanger member with the work from the work site to the removal site. The first transfer path and the second transfer path are vertically separated from each other, and the corresponding hanger members are transferred by their own weight by being inclined at a predetermined angle. In the present invention, the hanger members are sequentially sent out to the work site to improve the workability. However, it is desired that this type of device configuration contribute to power saving.

  Therefore, an elevating part capable of accommodating the hanger member and being movable up and down is provided at the work site of the transport device of the present invention. The elevating unit is urged in the ascending direction, and moves the hanger member with the work to the second position by the weight of the hanger member with the work from the ascending state in which one hanger member transferred from the first transfer path is housed. It is configured to be displaced to a lower state where it can be transferred to a transfer path. On the first transfer path side, there is provided an upper lock mechanism which penetrates into the movement path of the hanger member on the first transfer path and is locked by a hanger member arranged in the immediate vicinity of the elevating section. The upper lock mechanism is configured such that the pressing force of the elevating unit that rises from the descending state is mechanically transmitted to retreat from the movement path of the hanger member on the first transfer path, and that the hanger member housed in the elevating unit in the ascending state is moved. The pressing force is transmitted mechanically and penetrates into the movement path of the hanger member on the first transfer path. Further, on the second transfer path side, there is provided a lower lock mechanism which is locked by the elevating unit in the lowered state. The lower lock mechanism is configured to mechanically transmit the pressing force of the hanger member with a work transferred from the elevating unit in the lowered state onto the second transfer path, and release the engagement with the elevating unit.

  In the present invention, the work can be attached to the hanger member with good workability by sending out and storing one hanger member in the elevating portion in the ascending state at the work location. At this time, the locking state of the hanger member on the first transfer path and the upper lock mechanism (the intrusion state of the same mechanism) is released by using the pressure at the time of lifting of the lifting / lowering part, so that the lifting / lowering part in the raised state is released. One hanger member can be sent out and stored. Further, the upper lock mechanism is returned to the original state (intruded state) again by using the pressing force of the hanger member accommodated in the elevating unit, so that the upper lock mechanism can be locked to the hanger member on the first transfer path. Thus, in the present invention, the upper lock mechanism is configured to contribute to power saving by mechanically transmitting the pressing force of the lifting / lowering portion and the hanger member. Further, in the present invention, the lifting section is lowered by the weight of the hanger member with the work, and the lowering mechanism maintains the lowered state of the lifting section, so that the hanger member with the work is stably moved from the lifting section to the second transfer path. Can be sent to Then, the lock of the lower lock mechanism is released by mechanically transmitting the pressing force of the hanger member with the work on the second transfer path, so that power is saved.

  The transport device according to a second aspect of the present invention is the transport device according to the first aspect, wherein the first transfer path includes a nearest hanger member disposed immediately adjacent to the elevating unit and another hanger member disposed adjacently. I have. The upper lock mechanism has a first arm portion that enters the movement path of the hanger member on the first transfer path and is locked by the nearest hanger member, and enters the movement path of the hanger member on the first transfer path. A second arm portion locked to another hanger member is provided so as to be mechanically interlockable. Then, the first arm unit is mechanically transmitted with the pressing force of the elevating unit that ascends from the descending state, retreats from the movement path of the hanger member on the first transfer path, and receives the latest force stored in the elevating unit in the ascending state. In this configuration, the pressing force of the hanger member is mechanically transmitted and enters the movement path of the hanger member on the first transfer path. In addition, the second arm portion enters the movement path of the hanger member on the first transfer path in conjunction with the retreat of the first arm portion, and the hanger member on the first transfer path in conjunction with the entry of the first arm portion. This is a configuration to retreat from the moving route. In the present invention, one hanger member (nearest hanger member) is accommodated in the elevating unit by moving the first arm of the upper lock mechanism using the pressing force of the elevating unit and the hanger member. At this time, by associating the second arm with the first arm, it is possible to more reliably accommodate one hanger member in the elevating unit. That is, when the first arm portion is in the retracted state (unlocked state), the second arm portion is locked to another hanger member, whereby this another hanger member is erroneously moved to the lifting / lowering portion side. That can be avoided as much as possible. Further, when the first arm is in the intruded state (locked state), another hanger member is transferred to the first arm side by the second arm being in the retracted state, and the other hanger member is moved to the next arm. Will be arranged in the immediate vicinity of the elevating part as a hanger member immediately adjacent to the above.

Has been fixed. In addition, on the upper surface of the upper positioning portion 40 on the right side, a maintenance bolt SB for maintaining the standing posture of the weight link portion 8c is provided. The retaining bolt SB is fixed to the upper positioning portion 40 via a bolt bracket SBB, and supports the weight link portion 8c in a substantially upright posture from the front. The right end side of the connecting rod 10c is fixed midway in the vertical direction of the weight link portion 8c, and the tilting arm portion 12c is fixed to the left end side of the connecting rod 10c. Here, the connecting rod 10c shown in FIGS. 12 and 13 is a shaft-like portion extending leftward from the weight link portion 8c, and is inserted into the upper portions (through holes) of the pair of rear lower support portions 52 and 53. It is supported in a rotatable state. The tilt arm 12c is a rod-shaped member extending downward from the left end side of the connecting rod 10c. The tilting arm portion 12c enters the movement path (P2) of the hanger member on the second transfer path 80 while extending downward.

  In this embodiment, with reference to FIGS. 12 and 14, the tilt arm 12 c and the lower lock body 2 c are interlocked via the connecting rod 10 c by the pressing force of the hanger member with work WH described later. It has a moving configuration. For example, as shown in FIG. 14, when the tilting arm portion 12c is pushed by the hanger member with work WH transferred in the second transfer path 80, the tilting arm portion 12c gradually tilts backward as it moves downward while rotating the connecting rod 10c. Becomes When the connecting rod 10c rotates, the weight link portion 8c gradually inclines backward toward the lower side similarly to the tilt arm portion 12c, and the movement of the weight link portion 8c is locked via the connecting link portion 4c. It is transmitted to the link 6c. That is, by pushing the connecting link portion 4c forward while the weight link portion 8c is tilted, the locking link portion 6c gradually tilts rearward as it goes downward with the front shaft member 7c as a base point. For this reason, the lower part of the locking link 6c moves in the engaging and disengaging direction (rear in each drawing) away from the locking projection 7a of the elevating part AM.

  Further, when the hanger member with work WH in FIG. 14 moves backward while pushing the tilt arm 12c upward, the pressing force of the hanger member with work WH is not applied to the tilt arm 12c. In this case, the weight link portion 8c returns to the original state at the weight portion 9c as shown in FIG. 12, whereby the entire lower lock mechanism CM returns to the original state. That is, the movement to return to the original position of the weight link portion 8c is transmitted to the tilting arm portion 12c through the connecting rod 10c, and also transmitted to the locking link portion 6c via the connecting link portion 4c. In this way, the tilting arm portion 12c returns to the original state in which it has entered the movement path (P2) of the hanger member on the second transfer path 80. Also, by returning the locking link 6c to the original state, the lower portion of the locking link 6c is located at a position where it can be locked to the locking projection 7a of the lifting / lowering unit AM.

[Regulatory Department]
The restricting portion DM shown in FIGS. 5, 13, and 15 is a member that restricts the movement of the hanger member with work WH on the second transfer path 80 from returning to the elevating portion AM. Referring to FIG. 15, the restricting portion DM is a rectangular plate material extending vertically below the second transfer path 80, and has a lower end that is thick and protrudes left and right. The upper front side of the regulating portion DM has a tapered shape that gradually inclines backward as it goes upward. The restricting portion DM is attached to the pair of lower support columns 40 and 41 of the base 10 and is disposed below the second transfer path 80 as shown in FIGS. For example, a plate-like mounting plate portion 2d is fixed below the tip of the lower support column 41 on the left side shown in FIG. 15, and the mounting plate portion 2d is in a state of being gradually inclined downward toward the outside. The mounting shaft 4d protrudes from the lower surface of the mounting plate 2d, and the front edge of the mounting plate 2d is provided with a thickening stop 6d. Therefore, by attaching and fixing the mounting shaft 4d in the vertical center of the restricting portion DM, the restricting portion DM is disposed so as to be tiltable back and forth with respect to the mounting shaft 4d. At this time, the upper side of the restricting portion DM is arranged so as to be in contact with the detent portion 6d, and the lower side of the restricting portion DM can ride on the detent portion 6d while slightly floating from the mounting plate portion 2d. Keep it in a state.

  In the present embodiment, when the hanger member with work WH of FIG. 15 is transferred on the second transfer path 80 as described later, each locking wire portion 4h of the hanger member with work WH corresponds to the regulating portion DM. Respectively in contact with the tapered upper front side. Then, the locking wire portion 4h climbs over each restricting portion DM while tilting it rearward, whereby the rearward movement of the hanger member with work WH is allowed. In the restricting portion DM in this state, the upper side in contact with the hanger member with work WH is inclined rearward and separated from the detent portion 6d, and the lower side of the restricting portion DM rides on the detent portion 6d while tilting forward. State. Then, after the hanger member with work WH has passed, the restricting portion DM naturally returns to its original state with the weight of the lower portion of the thickened portion. Further, it is assumed that the hanger member WH with a work tries to move to the lifting / lowering part AM side (the front side in FIG. 15). At this time, even if the locking wire portion 4h presses the regulating portion DM and tries to incline it in the opposite direction, the upper side of each regulating portion DM abuts against the locking portion 6d, so that the regulating portion DM is tilted in the opposite direction. Will be blocked. For this reason, since the locking wire portion 4h abuts on the upper side of the regulating portion DM and further movement is regulated, the movement of the hanger member with work WH to the elevation portion AM side is prevented.

Keep it in a state. By rotating the horizontal holding portion 10e about the axis by the depression of the operation arm 30e, the connection shaft portion 5e at the front end of the operation portion 4e is pushed down, thereby releasing the connection portion EM gradually inclined upward toward the rear. Posture can be. When the downward pressing of the operation portion 4e is stopped, the connecting portion EM returns to the original horizontal state by its own weight.

[Placement work of the trolley on the transfer device (unloading point)]
Prior to the mounting work of the work W, the cart TM is arranged at the take-out point 6 of the transfer device 2 as shown in FIGS. At this time, by moving the cart TM forward along each of the positioning portions 30 to 33 of the transport device 2, the transport device 2 and the truck TM can be arranged so as to substantially coincide in the left-right direction. In the position thus positioned, the carry-in transfer path 7t of the cart TM is disposed at a position substantially coincident with the first transfer path 70 of the transport device 2 in the left-right direction, and the carry-out transport path 8t of the cart TM is connected to the transport device. The second transfer path 80 is disposed at a position substantially coincident with the second transfer path 80. Then, the cart TM is connected to the transfer device 2 and fixed in position by a connecting portion EM provided on the base 10.

After the connecting column 4t on the front side of the bogie TM gets over the inclined plate portion 7e, the connecting portion EM rotates downward around the holding column 20e and returns to the original horizontal state. After the connecting portion EM returns to the horizontal state in this way, the inclined plate portion 7e is fitted and locked (connected) between the pair of connecting pillar portions 4t of the cart TM. Then, in a state where the transport device 2 and the truck TM are connected, the front sides of the carry-in transfer path 7t and the carry-out transport route 8t of the truck TM shown in FIG. 3 are released by the release arms 72 and 82 of the transport device 2. To open.

[Transfer work of hanger members]
Referring to FIGS. 1 and 18, a plurality of hanger members H are arranged in carry-in transfer path 7 t of cart TM, and the plurality of hanger members H are sent out from carry-in transfer path 7 t to first transfer path 70. I will go. At this time, the carry-in transfer path 7t and the first transfer path 70 are arranged so as to be substantially connected to each other, and the two transfer paths are gradually inclined downward as going forward. Therefore, each hanger member H can be sent out from the carry-in transfer path 7t to the first transfer path 70 by its own weight. As described above, since each hanger member H is naturally sent out from the cart TM to the transport device 2, it is not necessary to transfer each hanger member H manually, and the configuration contributes to improvement of workability. Then, each hanger member H is transferred through the first transfer path 70, and is locked by the upper lock mechanism BM before the elevating unit AM. That is, as shown in FIG. 9, in the upper lock mechanism BM, the rear claw portion 12b of the first arm portion 10b in the locked state is in a state of entering the transfer path of the hanger member H on the first transfer path 70. . For this reason, each hanger member H is locked by the front claw portion 13b in front of the elevating section AM and is prevented from being transferred to the elevating section AM, and the first hanger member H1 is held immediately near the elevating section AM. Then, the second hanger member H2 is retained.

  Next, referring to FIGS. 9 and 10, the lock of the upper lock mechanism BM (first arm portion 10 b) is released, and the first hanger is moved from the first transfer path 70 to the elevating portion AM of the work location 4. The member H1 is sent out and stored. The first arm portion 10b is configured to retreat from the movement path (P1) of the hanger member on the first transfer path 70 by mechanically transmitting the pressing force of the elevating section AM rising from the lowered state. That is, the first arm 10b is swung from the locked state of FIG. 9 to the unlocked state of FIG. 10 by raising the elevating part AM and pushing up the first arm 10b by the push-up portion 2a of the elevating part AM. It can be moved and displaced. At this time, the rear claw portion 12b of the first arm portion 10b gradually moves upward from the state of entering the moving path (P1) and retreats from the moving path (P1). By retracting the rear claw portion 12b of the first arm portion 10b from the movement path (P1) in this manner, the first hanger member H1 is moved up and down from the first transfer path 70 as shown in FIGS. It is transferred to AM.

  Further, in the present embodiment, referring to FIGS. 9 and 10, the second arm 20b is interlocked with the first arm 10b which is displaced to the unlocked state, and the second hanger member is connected to the second arm 20b. H2 transfer can be prevented. In the second arm portion 20b, the rear side of the second arm portion 20b gradually moves downward as the first arm portion 10b is displaced (oscillated) from the locked state to the unlocked state. That is, the second arm portion 20b swings in the opposite direction to the first arm portion 10b, and the rearmost claw portion 22b of the second arm portion 20b moves along the movement path (P1) of the hanger member on the first transfer path 70. Is invaded. In this way, as shown in FIG. 10, the last claw portion 22b enters the movement path (P1) and comes into contact with and is locked by the second hanger member H2. In this manner, the second hanger member H2 is locked and retained by the last claw portion 22b, so that only the first hanger member H1 can be more reliably transferred to the elevating section AM.

  Then, as shown in FIG. 11, after the first hanger member H1 is accommodated in the elevating section AM, the upper lock mechanism BM is returned to the original state. At this time, the first arm portion 10b of the upper lock mechanism BM transmits the pressing force of the hanger member H accommodated in the elevating section AM in the ascending state mechanically to the moving path of the hanger member on the first transfer path 70 ( P1) (return to the original state). That is, in the unlocked first arm portion 10b of FIG. 10, the front claw portion 13b is arranged at a position where the hanger member H accommodated in the elevating portion AM in the ascended state can be received. Then, the first hanger member H1 presses the front claw portion 13b while moving into the elevating section AM, whereby the front claw portion 13b is jumped upward by the pressing force of the first hanger member H1. When the front claw portion 13b is flipped up, the first arm portion 10b rotates around the first shaft member 3b of the fixed plate 2b, and returns to the locked state in which the rear side relatively faces downward. It will be. Further, in the second arm portion 20b of this embodiment, as the first arm portion 10b is displaced (oscillated) from the unlocked state to the locked state, the rear side of the second arm section 20b gradually moves upward. In this way, as shown in FIG. 10, the rear claw portion 22b is retracted upward from the movement path (P1), so that the second hanger member H2 is transferred beyond the rear claw portion 22b to the rear locking claw, The next hanger member is in a state of being held immediately adjacent to the elevating unit AM.

[Attaching work to hanger member]
Then, at the work location 4 of the transport device 2 shown in FIG. 18, the elevating part AM in the ascending state is arranged in a state where one hanger member H is housed. Since the elevating part AM is urged in the ascending direction, it is stably held in the ascending state. For this reason, the work W can be attached to the hanger member H of the elevating part AM with good workability at the work location 4. The lifting unit AM is configured to be displaced from the raised state to the lowered state in FIG. 19 in which the hanger member with work WH can be transferred to the second transfer path 80 by the weight of the hanger member with work WH. Therefore, the work W is locked to the hanger member H in the housing portion to form a hanger member with work WH. When the work W is attached to the hanger member H of the elevating section AM in this way, as shown in FIG. 4, the wire material 12a is pulled toward the elevating section AM that houses the relatively heavy hanger member WH with a work. For this reason, the lifting / lowering portion AM containing the hanger member WH with the work descends along the left and right guide bars 60 and 61 while pulling up the weight portion 10a via the wire material 12a.

In locking the lower lock mechanism CM, referring to FIG. 12, the locking projection 7a of the lifting / lowering portion AM is locked to the locking link 6c of the lower lock mechanism CM (lower lock main body 2c). . In other words, the locking convex portion 7a moves along with the lifting edge AM while pushing the front edge of the locking link portion 6c slightly backward while descending together with the elevating portion AM. After the elevating part AM is displaced to the lowered state, the locking convex part 7a is locked to the lower end of the locking link part 6c, so that the elevating part AM is prevented from moving upward. . Then, as shown in FIG. 20, the hanger member with work WH is sent out from the elevating section AM to the second transfer path 80, and further transferred to the unloading point 6 through the second transfer path 80. In this embodiment, the movement of the hanger member WH with the workpiece to the lifting / lowering portion AM is regulated by the action of each regulating portion DM attached to the second transfer path 80 side. For this reason, the hanger member with work WH can be more reliably transferred to the extraction location 6 through the second transfer path 80.

  Then, referring to FIG. 20, after the hanger member with work WH is sent out to the second transfer path 80, the lock of the lower lock mechanism CM is released to disengage the elevating unit AM. At this time, referring to FIG. 14, the lower lock mechanism CM mechanically transmits the pressing force of the hanger member WH with the workpiece transferred onto the second transfer path 80 from the elevating part AM in the lowered state, and the elevating part AM Is released. In other words, in the lower lock mechanism CM, the tilting arm portion 12c is pushed by the hanger member with work WH transferred in the second transfer path 80, and is gradually tilted backward as it goes downward while rotating the connecting rod 10c. Becomes By transmitting the rotation of the connecting rod 10c to the locking link 6c through the weight link 8c and the connecting link 4c, the locking link 6c gradually moves rearward as it goes downward with the front shaft 7c as a base point. Incline. By moving the lower portion of the locking link 6c in the engaging and disengaging direction away from the locking projection 7a of the elevating part AM in this manner, the elevating part AM can be disengaged from the lower lock mechanism CM. When the hanger member WH with the workpiece moves rearward beyond the tilt arm 12c, the lower lock mechanism CM uses the weight of the weight 9c of the weight link 8c to return to the original state shown in FIG. Will be returned. In addition, the lifting part AM (empty lifting part AM) disengaged from the lower lock mechanism CM is also displaced from the lowering state to the rising state by the weight of the weight 10a as shown in FIGS. Then, by moving the upper lock mechanism BM again in the ascending / descending section AM, the next first hanger member H1 is transferred from the first transfer path 70 into the ascending / descending section AM in the ascending state.

  In this embodiment, as shown in FIG. 20, the hanger member with work WH is sequentially transferred to the take-out point 6 through the second transfer path 80, and further sent out to the carry-out transfer path 8t of the bogie connected to the take-out point 6, as shown in FIG. I will go. After the sufficient hanger member WH with work is loaded on the carry-out transfer path 8t of the bogie TM shown in FIGS. 1 and 3, the connecting portion EM is operated to release the bogie from the transporting device 2 and the bogie. Remove TM.

One hanger member H can be sent out and stored in the elevating section AM. Further, the upper lock mechanism BM is returned to the original state (intrusion state) again by utilizing the pressing force of the hanger member H accommodated in the elevating section AM, thereby locking the hanger member H on the first transfer path 70. Make it possible. Thus, in the present invention, the upper lock mechanism BM is configured to contribute to power saving by mechanically transmitting the pressing force of the elevating unit AM and the hanger member H and moving the same. Further, in the present embodiment, the lifting / lowering portion AM is lowered by the weight of the hanger member with work WH, and the lowered state of the lifting / lowering portion AM is maintained by the lower lock mechanism CM, whereby the hanger member with work WH is moved from the lifting / lowering portion AM. It can be sent to the second transfer path 80 stably. Since the locking of the lower lock mechanism CM is released by mechanically transmitting the pressing force of the hanger member with work WH on the second transfer path 80, the configuration contributes to power saving. Therefore, according to the present embodiment, it is possible to provide the transfer device 2 that contributes to power saving while improving workability. In particular, as described above, the transfer device 2 of the present embodiment performs the work of attaching the work W at the work location 4 manually, but does not rely on human work as much as possible for other transfer work and loading / unloading work to the cart (touchless). ) Configuration.
