Japanese Utility Model Publication No. 4-107166

However, in the configuration described in Patent Document 1, since the fluid pressure source and control means necessary for operating the cylinder unit mounted on the transporting vehicle itself must be mounted on each transporting vehicle, In the transportation facility using a large number of transportation vehicles, the facility cost becomes very high. Of course, in general, since the turntable is rotated while the transporting traveling body is stopped at the constant stopping position set in the traveling route of the transporting traveling body, the turntable is attached to this fixed stopping position. It is possible to configure so that the fluid pressure source and control means on the ground side can be used, but for the fluid pressure supply path and the control means between the carrier body for transport and the fluid pressure source and control means on the ground side. It is not a fundamental solution because it requires a detachable connector for the current path. Therefore, it is most desirable to install the turntable rotation driving means itself on the ground side of the fixed stop position of the transporting vehicle, but a suitable configuration that can be easily implemented has not been proposed.

The present invention proposes a transportation facility capable of solving the above-mentioned conventional problems, and the transportation facility according to the present invention is intended to facilitate the understanding of the relationship with the examples described later. The reference numerals used in the description of the embodiment are shown in parentheses, and are set on the travel route of the transporting vehicle (1) provided with the turntable (8) for loading transported objects. A turntable rotation drive means (32) for rotating and driving the turntable (8) of the transporting vehicle (1) stopped at the constant stop position is provided at a constant stop position of the transporting vehicle (1). In the transport facility using a transporting vehicle with a turntable, at least one driven portion for rotation drive (13) is provided at the bottom eccentric position of the turntable (8), and the turntable rotation drive means ( 32) is a movable table (36) that reciprocates between a retracted position and an operating position that are separated in the horizontal lateral direction orthogonal to the traveling direction of the transporting vehicle (1), and on this movable table (36). Is provided with a movable body (39) that reciprocates between a backward limit position and a forward limit position that are separated from each other in the traveling direction of the transporting vehicle (1), and the movable table (39) includes the movable table ( An engaging portion (recessed groove portion 39a) is provided for engaging and disengaging the driven portion for rotation (13) in the reciprocating movement direction of the movable table (36) by reciprocating movement of (36), and traveling for transport at a fixed stop position. When the body (1) is stopped, the movable body (39) in either the retreat limit position or the forward limit position on the movable table (36) in the retracted position is the driven portion for rotation drive ( 13) is located on the lateral side, and the movable base (36) is moved from this state to the operating position so that the rotation drive driven portion (13) engages with the engaging portion (concave groove portion) of the movable body (39). 39a) and the movable body (39) moves from this state to the forward limit position or the backward limit position, whereby the turntable (8) is rotationally driven in a forward or reverse direction by a predetermined angle. It is configured to be.

According to the present invention having the above-mentioned structure, the turntable rotation driving means needs only the at least one rotation driving driven part attached to the bottom of the turntable as the turntable side, and the traveling path of the transporting vehicle. At the fixed stop position for rotating the turntable, which is set inside, there are only the movable table and its driving means as the turntable rotational driving means, and the movable body and its driving means on the movable table. It can be carried out at a very low cost as a whole even in the transportation facility using the traveling body. Moreover, in order to rotate the turntable in the positive direction by a fixed angle at the fixed stop position, it is necessary to rotate the turntable in the reverse direction by the fixed angle at another fixed stop position lower than this to return the turntable to the original direction. Although it may occur, the turntable rotation drive means of the same configuration is installed at any fixed stop position, and simply selects whether the reciprocating movement of the movable body is performed from the backward limit position or the forward limit position. Since the turntable can be driven to rotate by a fixed angle in either forward or reverse directions, it can be implemented at a very low cost compared with the case where two types of turntable rotation driving means having different configurations are required. You can

In the case of carrying out the present invention, a cylinder unit (40) is provided as a drive means for reciprocating the movable body (39) with respect to the movable table (36), and the movable table (36) includes the movable body (39). A stopper means (41/42) for receiving the (39) at the backward limit position or the forward limit position is provided, and the stopper main body (43) for receiving the movable body (39) at the fixed position is provided on the stopper means (41/42). Then, a buffer damper (44) that is pressed by the movable body (39) immediately before the movable body (39) abuts on the stopper body (43). According to this structure, the cylinder unit has a simple structure in which the movable body is reciprocally moved on the movable table, and at least the turntable on which the objects to be conveyed are loaded from the forward limit position and the backward limit position of the movable body. The stopper means should be provided on the side where the movable body travels when it is rotated (both the forward limit position and the backward limit position when the transported object is loaded in either forward or reverse rotation). This allows the cylinder unit to absorb the shock when the movable body collides with the stopper at the stroke limit, even if the movable body is simply driven at the required speed. It is possible to change the direction of the object to be conveyed efficiently, safely and accurately, since it is possible to prevent the object from being unduly displaced.

Further, the driven parts for rotation driving (13, 14) are separated from each other in the traveling direction of the transporting vehicle (1) by a constant angle of less than 180 degrees on a virtual arc line concentric with the rotation center of the turntable (8). The turntable rotation driving means (32) may be provided at two places, and one of the two rotation driving driven parts (13, 14) may be used. According to this structure, even when the turntable needs to be rotated at an unreasonably large angle in one rotation operation, the turntable is rotated at the first fixed stop position set in the traveling route of the transporting vehicle. One of the two rotary drive driven parts is used to rotate forward (or reverse) by a fixed angle, and at the next constant stop position, the other rotary drive driven part of the two rotary drive driven parts is used. Thus, the turntable can be further rotated forward (or reverse) in the same direction by a fixed angle, which facilitates implementation.

A turntable lock releasing means 33 for releasing the locked state of is provided. Further, the transporting body locking means 34 for transportation is disposed at all the fixed stop positions.

As shown in FIGS. 5 to 9, the turntable rotation driving means 32 is laterally moved laterally with respect to the traveling direction of the transporting vehicle 1 by a plurality of slide guide rails 35a to 35c provided on the base 35. A movable strip 36, which is movably supported and is long in the traveling direction of the transporting vehicle 1, is disposed between the movable strip 36 and the base 35, and the movable strip 36 is moved to each fixed stop position. Cylinder unit 37 for lateral movement between the retracted position laterally laterally away from the rotation axis of the turntable 8 of the transporting vehicle 1 stopped at the operating position and the operating position close to the rotation axis of the turntable 8 A movable body 39 supported by a slide guide rail 38 laid on the strip-shaped movable base 36 so as to be reciprocally movable in parallel with the traveling direction of the transport traveling body 1, and between the movable body 39 and the strip-shaped movable base 36. A cylinder unit 40 that is arranged to move the movable body 39 back and forth between a backward limit position and a forward limit position, and a belt-shaped movable table 36 for stopping the movable body 39 at the backward limit position and the forward limit position. It is composed of stopper means 41, 42 disposed in the.

On the movable body 39, there is provided a recessed groove portion 39a penetrating in the left-right lateral direction orthogonal to the reciprocating movement direction thereof. As shown in FIG. 8, the recessed groove portion 39a has such a height that the rotary drive driven portions 13, 14 (rollers 31a, 31b) disposed below the turntable 8 can be just fitted in the lateral direction. It has a width. Further, as shown in FIG. 9, the stopper means 41, 42 are composed of a stopper body 43 and a shock absorbing damper 44. The stopper body 43 has a screw shaft 43b which penetrates the support member 43a mounted on the belt-shaped movable base 36 in parallel with the reciprocating direction of the movable body 39, a lock nut 43c for positioning the screw shaft 43b, and a tip of the screw shaft 43b.

It is configured.

As shown in FIGS. 5 to 7, the turntable unlocking means 33 includes a vertical support shaft 46a erected on a base 45, an operation arm 46b rotatably supported around the vertical support shaft 46a, Below the operation arm 46b, a driven lever 46c rotatable integrally with the operation arm 46b, a support member 47a mounted on the base 45, and a swinging motion of the support member 47a around a vertical support shaft 47b. The cylinder unit 47c is freely supported, and the piston rod of the cylinder unit 47c is connected to the free end of the driven lever 46c. 10 and a working posture in which the operated portion 29 at the tip of the lock lever 25 of the turntable locking means 15 is pushed to switch the lock lever 25 to the unlocked posture, as shown in FIG. It is constructed so that it can be swung within a range. As a matter of course, when the operation arm 46b is in the retracted posture, the transporting vehicle 1 can pass through the fixed stop position without being interfered by the turntable lock releasing means 33.

As shown in FIG. 5, the transporting traveling body locking means 34 disposed at the constant stop position can clamp the pinched columnar body 6 of the transporting traveling body 1 stopped at the constant stop position from both front and rear sides. A pair of holding pieces 48a and 48b that can be horizontally opened and closed and a cylinder unit 49 that drives the pair of holding pieces 48a and 48b to open and close are provided. As shown by the solid line in FIG. , 48b are open, the transporting vehicle 1 can be run without interfering with the transporting vehicle locking means 34.

When the transporting vehicle 1 is traveling forward on the travel route, as shown in FIG. 5, in the turntable 8, the locking roller 26 of the lock lever 25 in the turntable locking means 15 is located inside the protrusion 20. The front end in the length direction of the transported object W supported by the transported object support base 9 by being fitted in the adjacent locking recesses 17 is locked in a direction facing the forward traveling direction of the transporting vehicle 1. .. The driven portions 13 and 14 (rollers 31a and 31b) for rotation drive on the lower side of the turntable 8 are arranged side by side in the lateral direction orthogonal to the traveling direction of the transporting vehicle 1. If the transporting vehicle 1 that has traveled forward in this state is stopped at the first constant stop position for rotating the turntable in the forward direction by 90 degrees, the pair of clamping pieces 48a of the transporting vehicle locking means 34, By closing 48b to clamp the pinched columnar body 6 of the transporting vehicle 1 from both front and rear sides, the transporting vehicle 1 can be locked at the first fixed stop position. By operating the turntable rotation driving means 32, the turntable 8 is rotated by 90 degrees in the positive direction (counterclockwise in the illustrated example), and the length direction of the transported object W supported is changed to a horizontal direction at a right angle. Can be changed.

That is, the cylinder unit 37 is operated to move the movable strip 36 laterally from the retracted position to the working position, and as shown in FIG. 10, the movable body 39 at the retracted limit position on the movable strip 36 is moved to the transporting body. The rotation driving driven portion 13 on the first side is moved closer to the side, and the roller 31a, which is the rotation driving driven portion 13, is relatively moved into the concave groove portion 39a of the movable body 39. Thereafter, the cylinder unit 47c of the turntable lock releasing means 33 is operated to switch the operation arm 46b from the retracted posture shown in FIG. 5 to the working posture shown in FIG. 10, and the turntable of the transporting vehicle 1 is moved by the operation arm 46b. The operated portion 29 of the lock lever 25 in the lock means 15 is pushed toward the center of rotation of the turntable 8 to switch the lock lever 25 to the unlocked posture against the biasing force of the compression coil spring 27f of the biasing means 27. As a result, the locking roller 26 of the lock lever 25 withdraws inward from the locking recess 17 of the guide member 16 on the turntable 8 side, and the lock on the turntable 8 is released.

Next, by operating the cylinder unit 40 of the turntable rotation drive means 32 to move the movable body 39 forward from the backward limit position shown in FIG. 10 to the forward limit position shown in FIG. 11, the concave groove portion of the movable body 39 is moved. The turntable 8 is rotationally driven by 90 degrees in the positive direction via the driven part for rotation driving 13 (roller 31a) fitted to the 39a, and thereafter, as shown by a phantom line in FIG. The operation unit 46b is returned to the original retracted posture by the cylinder unit 47c of the releasing means 33, and the lock lever 25 is returned from the unlocked posture to the lock acting posture by the urging force of the compression coil spring 27f of the urging means 27 to lock the lock. The turntable 8 is locked by fitting the locking roller 26 of the lever 25 into the locking recess 18 at the intermediate position of the guide member 16 of the turntable 8 which is rotated 90 degrees in the forward direction. When the movable body 39 reaches the forward limit position, the movable body 39 is received by the stopper body 43 of the stopper means 42. At this time, the movable body 39 does not collide with the stopper body 43 in a shocking manner, but rather the shock absorber damper 44 moves. Since it is received by the stopper body 43 in a state of being decelerated by the action, it is possible to avoid a dangerous situation in which the transported object W shifts due to a reaction when the turntable 8 rotates 90 degrees in the positive direction and stops.

By the above-described series of operations, the transported object support base 9 on the turntable 8 of the transporting traveling body 1 in the forward direction stopped at the first constant stop position rotates in the positive direction by 90 degrees, and the transported object support base 9 is rotated. The length direction of the transported object W supported above is a right-angled lateral direction rotated by 90 degrees in the positive direction. From this state, the cylinder unit 37 of the turntable rotation drive means 32 at the first fixed stop position is operated to laterally return the belt-shaped movable base 36 to the original retracted position, and the movable body 39 is rotated on the turntable 8 side. The driven part 13 for driving is laterally separated from the driven part 13 so that the driven part 13 (roller 31a) for rotational driving is relatively ejected from the concave groove 39a of the movable body 39, and the transporting body locking means 34 for transporting is provided. By opening the pair of holding pieces 48a and 48b and unlocking the transporting vehicle 1, the transporting vehicle 1 stopped at the first fixed stop position can be moved forward. As a result of the belt-like movable base 36 returning to the retracted position in the lateral direction, the movable base 39 separated from the rotary drive driven part 13 on the turntable 8 side is returned to the retracted limit position by the cylinder unit 40.

As described above, the turntable 8 of the transporting vehicle 1 stopped at the first fixed stop position is moved to 90 by using one of the rotation driving driven parts 13 and 14 for rotation driving. Is conveyed in the state in which the length direction of the conveyed object W supported on the conveyed object support base 9 is switched to the right-angled sideways direction rotated by 90 degrees in the positive direction by rotating the conveyed object W in the forward direction. It is possible to convey from the first fixed stop position to the lower side by the traveling body 1, but on the lower side from the first constant stop position, the second constant stop for additional 90 degree rotation of the turntable in the forward direction. If the position is set and the transporting vehicle 1 is stopped at the second constant stop position, the transporting vehicle locking means 34 at the second constant stop position is operated to move the transporting vehicle 1 concerned. Locked at the second fixed stop position. As shown in FIG. 12A, the turntable rotation drive means 32 at the second fixed stop position stops at the second fixed stop position because the strip-shaped movable base 36 is at the retracted position and the movable body 39 is at the retracted limit position. The rotation-driven driven portion 14 on the turntable 8 side of the transporting traveling body 1 is located laterally to the concave groove portion 39a of the movable body 39. In this state, the band-shaped movable base 36 is laterally moved to the working position by the cylinder unit 37, so that the movable body 39 at the retracted limit position moves closer to the rotary drive driven portion 14 on the turntable 8 side, and the movable body 39 moves. The rotary drive driven portion 14 (roller 31b) on the turntable 8 side is relatively fitted into the concave groove portion 39a of the body 39.

In this state, like the turntable lock release means 33 and the turntable rotation drive means 32 at the first fixed stop position, the turntable lock release means 33 at the second fixed stop position is activated as shown in FIG. 12B. The lock lever 25 of the turntable lock means 15 is switched to the release position, and the movable body 39 of the turntable rotation drive means 32 is moved forward from the backward limit position to the forward limit position while the lock of the turntable 8 is released. Thus, the turntable 8 can be further rotationally driven by 90 degrees in the positive direction via the rotationally driven portion 14 (roller 31b) fitted in the concave groove portion 39a of the movable body 39. At this time also, the movable body 39 is stopped by the function of the buffer damper 44 of the stopper means 42 without impact on the stopper body 43 at the forward limit position. Therefore, the movable body 39 is supported on the turntable 8 via the transported object support base 9. It is not necessary to cause the supported object W to be displaced. When the turntable 8 is additionally rotated by 90 degrees in the forward direction, the locking recess 19 adjacent to the protrusion 21 of the guide member 16 on the turntable 8 side corresponds to the locking roller 26 of the lock lever 25 in the released posture. Therefore, the lock lever 25 of the turntable locking means 15 is switched to the operating position, and the locking roller 26 thereof is set in the locking recess 19 of the guide member 16 as in the case of the operation at the first fixed stop position. The turntable 8 can be locked by fitting. After that, the strip-shaped movable base 36 of the turntable rotation drive means 32 is horizontally returned to the retracted position, and the rotary drive driven portion 14 on the turntable 8 side is moved from the recessed groove portion 39a of the movable body 39 at the forward limit position. The movable body 39 is moved backward to the original retracted limit position while being relatively separated.

As described above, at the second constant stop position, the turntable 8 that has been rotated 90 degrees in the positive direction at the first constant stop position is additionally rotated 90 degrees in the same direction. The longitudinal direction of the transported object W supported on the table 9 is 180 degrees inverted from the direction of the turntable 8 when traveling toward the first fixed stop position, and the second fixed stop position is obtained. The article W supported on the transporting traveling body 1 that travels from the bottom is transported in a state in which the front end in the longitudinal direction is located at the rear end side of the transporting traveling body 1 in the opposite direction. Become.

Below the second constant stop position, a third constant stop position for rotating the turntable 8 on the transporting carrier 1 in the opposite direction by 90 degrees, and further below this third constant stop position. It is possible to set a fourth fixed stop position for additionally rotating the turntable 8 on the transporting vehicle 1 in the opposite direction by 90 degrees. The retracted position of the movable body 39 of the turntable rotation drive means 32 disposed at the third fixed stop position or the fourth fixed stop position is set as the forward limit position on the belt-shaped movable table 36, and the transporting vehicle 1 is transported. Is stopped and locked at the third fixed stop position, the rotary drive driven part 14 of the two rotary drive driven parts 13, 14 on the turntable 8 side of the transporting vehicle 1 is driven by the turntable rotary drive. It is positioned laterally of the movable body 39 waiting at the forward limit position of the means 32. Therefore, after the transport traveling body 1 is stopped and locked at the third fixed stop position, when the strip-shaped movable base 36 of the turntable rotation driving means 32 is laterally moved to the working position by the cylinder unit 37, the strip-shaped movable base 36 is moved. When the movable body 39 waiting at the forward limit position moves closer to the rotary drive driven portion 14 on the turntable 8 side, the rotary drive driven portion 14 is fitted into the concave groove portion 39a of the movable body 39. Become.

In this state, the turntable lock releasing means 33 is operated to switch the lock lever 25 of the turntable locking means 15 to the lock releasing posture, and then the movable body 39 is moved by the cylinder unit 40 from the forward limit position to the backward limit position. As a result, the turntable 8 rotates 90 degrees in the opposite direction from the state shown in FIG. 12B to the state shown in FIG. 12A, and the transported object W supported by the transported object support base 9 moves from the first fixed stop position to the first position. (2) It is returned to the state of being oriented at a right angle when transported to the fixed stop position. Also at this time, the buffer damper 60 works to avoid a dangerous situation in which the transported object W moves with the transported object support base 9. When the movable body 39 reaches the retracted limit position and the turntable 8 is completely rotated by 90 degrees in the reverse direction and is locked by the turntable locking means 15, the cylinder unit 37 moves the belt-shaped movable base 36 to the original retracted position. The movable unit 39 is moved back to the forward limit position which is the retracted position by the cylinder unit 40.

As described above, the transported object W supported by the transported object support base 9 is transported from the third fixed stop position to the fourth fixed stop position in the state of being laterally oriented at a right angle again. When the body 1 arrives at the next fourth fixed stop position and is stop-locked, the turntable lock releasing means 33 and the turntable rotation driving means 32 provided at the fourth constant stop position are activated to turn the turntable. 8 is further rotated in the opposite direction by 90 degrees, so that the transported object W supported by the transported object support base 9 on the turntable 8 has its front end in the length direction directed to the front end side of the transporting carrier 1. It is possible to return to the initial state, that is, the initial state when the transported object W is transported toward the constant stop position.

That is, the turntable rotation driving means 32 provided at the fourth fixed stop position also retracts the movable body 39 of the turntable rotation driving means 32, similarly to the turntable rotation driving means 32 provided at the third constant stop position. The position is the forward limit position on the movable strip 36, and when the transporting vehicle 1 is stop-locked at the fourth fixed stop position, the transporting vehicle 1 has two positions on the turntable 8 side. Since the driven part for rotation drive 14 among the driven parts for rotation drive 13 and 14 is located on the lateral side of the movable body 39 waiting at the forward limit position of the turntable rotation drive means 32, By operating the turntable unlocking means 33 and the turntable rotation driving means 32 from the state, the turntable 8 is additionally rotated in the reverse direction by 90 degrees from the state shown in FIG. 12A to the state shown in FIG. The orientation of the transported object W supported by the upper transported object support base 9 can be returned to the initial state in which the front end thereof faces the front end side of the transporting vehicle 1.

In the above description, on the transporting traveling body 1 traveling toward the first fixed stop position, the transported object W is in the forward direction in which the front end in the longitudinal direction is located on the front end side of the transporting traveling body 1. Yes, the direction of the transported object W is rotated 90 degrees in the forward direction at the first constant stop position to switch to the right-angled lateral direction, and further rotated at 90 degrees in the forward direction at the next second constant stop position to reverse the direction. Then, at the third fixed stop position, it is rotated 90 degrees in the reverse direction to switch to the original right-angled sideways direction again, and at the final fourth fixed stop position, it is further rotated 90 degrees in the reverse direction to switch to the original positive direction. However, this description merely describes how to use the turntable rotation drive means 32 provided at each fixed stop position. In practice, the turntable rotation drive means 32 is actually moved from the fourth fixed stop position to the fourth fixed stop position. One of the fixed stop positions, or a fixed stop position for loading and unloading the transferred objects set separately from the fixed stop position for rotating the turntable, and the transferred object support base 9 on the turntable 8 It is possible to load and unload the objects W to be conveyed. In other words, switching the direction of the turntable 8 (transport target support 9) at each fixed stop position is for loading and unloading the transport target 1 on the transport body 1 or for working on the transport target W being transported. It will be related. In addition, the work for the transported object W supported and transported on the transported object support base 9 on the turntable 8 and the loading/unloading operation for the transported object W on the transported object support base 9 on the turntable 8 are performed as follows. It can be done by the operator.

Incidentally, the present invention relates to a driven part for rotation driving of a turntable on the transporting vehicle and a turntable rotation driving means on the side of the fixed stop position, which is set on the travel route of the transporting vehicle. The setting of the fixed stop position of the traveling body for rotationally driving the turntable, the rotation angle and the rotation direction of the turntable at each fixed stop position, etc. are not limited to those shown in the above-mentioned embodiment.

INDUSTRIAL APPLICABILITY The transport facility of the present invention can be utilized as a transport facility that can change the direction of loaded objects to be transported depending on the travel route section of the transporting vehicle.
