Japanese Utility Model Publication No. 4-107166

  However, in the configuration described in Patent Document 1, the turntable is directly connected to the turntable cylinder unit. Therefore, there is no possibility that the turntable will rotate without permission unless the cylinder unit is operated. When adopting a configuration in which the turntable of the transporting traveling body stopped at the fixed stop position is rotated by the turntable rotation driving means installed on the traveling route side at the fixed stop position, the transporting traveling body is moved from the fixed stop position. When the turntable is separated from the turntable rotation driving means while traveling, a turntable locking means is required to prevent the turntable from rotating unexpectedly. As a turntable lock means in this case, it is generally conceivable to automatically switch to a lock state in which the turntable is engaged when the turntable rotates a predetermined angle. Unlocking means for unlocking the turntable is required. In this case, the unlocking means can be installed at a fixed stop position of the transporting traveling body together with the turntable rotation driving means, but the turntable locking means on the transporting traveling body side and the unlocking means on the traveling route side can be installed. There has not been proposed a suitable configuration that can easily be put into practical use as a whole.

  The present invention is to propose a transport facility that can solve the conventional problems as described above, the transport facility according to the present invention, in order to make it easier to understand the relationship with the embodiments described below. When the reference numerals used in the description of the embodiment are shown in parentheses, the turntable (8) provided for the transported traveling body (1) for loading the transported object has the turntable (8). Turntable locking means (15) for locking the rotation of the transfer table (8) is provided, and the turntable locking means (15) is provided at a fixed stop position for the turntable rotation operation set in the traveling route of the transporting traveling body. In the transport equipment provided with the turntable lock releasing means (33) for releasing the lock of (15), the turntable lock means (15) is provided with a guide member (16) attached to the lower side of the turntable (8). And a support on the transporting carrier (1) side The guide member (16) has an inner peripheral edge concentric with the turntable (8) and a locking recess (17-19) formed at a predetermined angular interval on the inner peripheral edge. The lock lever (25) abuts and rolls on the inner peripheral edge of the guide member (16), and is a locking roller (26) that can be fitted to and removed from the locking recesses (17 to 19). And an operated portion (29), and an urging means (27) for urging the lock lever (25) in a direction in which the locking roller (26) is brought into contact with the inner peripheral edge of the guide member (16), The turntable unlocking means (33) includes an operating arm (46b) and a driving means (cylinder unit 46c) for operating the operating arm (46b). The operating arm (46b) 1) The driving means (cylinder unit 46c) moves the retracted position of the lock lever (25), which is located outside the movement path of the operated portion (29), along with the travel of the lock lever (25). By being swung to the working posture, the operated portion (29) of the lock lever (25) is pressed to swing the lock lever (25) against the urging means (27), The locking roller (26) is detached from the locking recesses (17 to 19).

  According to the present invention having the above-described configuration, when the turntable is rotated, the locking roller of the lock lever rolls in a state of contact with the turntable-side guide member and the concentric inner peripheral edge of the turntable, When the turntable rotates by a predetermined angle, the locking roller fits into one of the locking recesses on the inner peripheral edge to lock the turntable. When the transporting vehicle stops at the fixed stop position for the turntable rotation operation, the locking means is operated by operating the driving means of the turntable unlocking means to swing the operation arm from the retracted position to the operating position. The locking roller is pivoted in a direction in which the lever is disengaged from the locking concave portion against the urging means, and the lock on the turntable is released.

  As described above, the lock of the turntable is automatically performed, and the unlocking of the turntable can be performed only by swinging one lock lever by the driving means on the traveling path side. According to the configuration, the turntable can be accurately locked at a predetermined angle simply by providing the locking recesses at the inner peripheral edge of one guide member at an angular interval for locking the turntable, and locking the turntable. In comparison with the case where a plurality of stoppers must be separately mounted on the transporting traveling body side for each angle to be performed, the structure is much simpler and can be implemented easily. Moreover, the lock lever needs to be urged by the urging means in the locking action direction, but after the lock lever is swung against the urging means to release the lock, even the turntable starts to rotate. Then, only by releasing the lock lever, the locking roller automatically abuts and rolls on the inner peripheral edge of the guide member to prepare for the automatic lock of the turntable at the next angle. It is not necessary to hold the lock lever in the unlocked position until the lock angle is reached, and it is not necessary to hold the lock lever in the standby position in which the stopper corresponding to the next lock angle can be automatically engaged. In other words, the desired turntable locking action can be accurately and reliably achieved, despite the fact that the structure is extremely simple and can be implemented at low cost.

  When carrying out the present invention, at both ends of the inner peripheral edge of the guide member (16), provided with projections (20, 21) for receiving the locking roller (26) of the lock lever (25), at least the The locking recesses (17, 19) can be provided at two places adjacent to the inside of the projections (20, 21). According to this configuration, not only the stopper member when the turntable reaches the end of the rotation range can be constituted by one guide member forming the locking concave portion, but also the turntable can be moved in the rotation range. When reaching the end, the locking roller on the lock lever side can be securely fitted into the corresponding locking concave portion.

  Further, the lock lever (25) is arranged horizontally left and right and transversely perpendicular to the traveling direction of the transport traveling body (1), and has one end pivotally supported by the transport traveling body (1). ), The pin-shaped operated portion (29) can be protruded downward from the free end. According to this configuration, the lock lever and the turntable unlocking means for operating the operated portion of the lock lever can be arranged side by side in the left-right and lateral directions of the transporting traveling body. It becomes easy to install the turntable lock releasing means in a state where it does not interfere with the lever and various members attached thereto.

  Further, a support means (28) for supporting between the operated portion (29) at the free end of the lock lever (25) and the locking roller (26) is provided on the transporting traveling body (1) side. The support means (28) includes a support member (28b) having one end attached to the mounting member (28a) on the side of the transport traveling body (1) and extending downward of the lock lever (25). A support plate (28c) attached to the upper end of the support member (28b) and supporting the lock lever (25) can be provided. According to this configuration, it is not necessary to constitute the long lock lever with a member having a large bending strength and to make the play at the pivot portion serving as the pivot center of the lock lever sufficiently small. The lock lever can be configured to be lightweight and inexpensive.

And the operating portion 29 at the tip of the lock lever 25 of the turntable locking means 15 as shown in FIG. And it is configured to be able to swing within a range of 90 ° between the working position for switching the lock lever 25 in the unlocking posture. Of course, when the operation arm 46b is in the retracted position, the transport traveling body 1 can travel through the fixed stop position without being interfered by the turntable lock releasing means 33.

  As shown in FIG. 5, the transport traveling body locking means 34 disposed at the fixed stop position can clamp the nipped columnar body 6 of the transport traveling body 1 stopped at the fixed stop position from both front and rear sides. 5, a pair of holding pieces 48a, 48b that can be opened and closed horizontally and a cylinder unit 49 that opens and closes the pair of holding pieces 48a, 48b. As shown by a solid line in FIG. , 48b are open, the transport traveling body 1 can travel without interfering with the transport traveling body locking means 34.

  As shown in FIG. 5, when the transporting traveling body 1 is traveling forward on the traveling route, the turntable 8 is configured such that the locking roller 26 of the lock lever 25 of the turntable locking means 15 is positioned inside the projection 20. The longitudinal front end of the transported object W supported by the transported object support table 9 is locked in a direction facing the forward traveling direction of the transport traveling body 1 by fitting into the adjacent locking recess 17. . The driven portions 13 and 14 (rollers 31 a and 31 b) for rotation driving on the lower side of the turntable 8 are arranged side by side in the horizontal direction perpendicular to the traveling direction of the transport traveling body 1. If the transporting traveling body 1 that has been traveling forward in this state is stopped at the first fixed stop position for rotating the turntable forward 90 degrees, a pair of holding pieces 48a, 48b is closed, and the columnar body 6 to be clamped of the transporting traveling body 1 is clamped from both front and rear sides, whereby the transporting traveling body 1 can be locked at the first fixed stop position. By operating the turntable rotation drive means 32, the turntable 8 is rotated by 90 degrees in the forward direction (counterclockwise in the illustrated example), and the length direction of the supported transported object W is set to the right angle sideways. Can be changed.

  That is, the cylinder unit 37 is operated to move the band-shaped movable table 36 from the retracted position to the operation position, and the movable body 39 at the retreat limit position on the band-shaped movable table 36 is moved as shown in FIG. The roller 31a, which is the driven portion 13 for rotation, relatively moves into the concave groove portion 39a of the movable body 39 by moving the roller 31a closer to the driven portion 13 for rotation drive on the first side. Thereafter, the cylinder unit 47c of the turntable unlocking means 33 is operated, and the operation arm 46b is switched from the retracted posture shown in FIG. 5 to the operation posture shown in FIG. The operated portion 29 of the lock lever 25 in the lock means 15 is pushed toward the rotation center of the turntable 8, and the lock lever 25 is switched to the unlocked position against the urging force of the compression coil spring 27 f of the urging means 27. As a result, the locking roller 26 of the lock lever 25 retreats 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, the cylinder unit 40 of the turntable rotation driving means 32 is operated to move the movable body 39 forward from the retreat limit position shown in FIG. 10 to the forward limit position shown in FIG. The turntable 8 is driven to rotate in the positive direction by 90 degrees through the rotation driving driven part 13 (the roller 31a) fitted to the turntable 39a, and thereafter, as shown by a virtual line in FIG. The operation arm 46b is returned to the original retracted position by the cylinder unit 47c of the release unit 33, and the lock lever 25 is returned from the unlocked position to the lock operation position by the urging force of the compression coil spring 27f of the urging unit 27, and the lock is released. The locking roller 26 of the lever 25 is rotated 90 degrees in the forward direction to the intermediate position of the guide member 16 of the turntable 8. By fitting the Rukakaritome recess 18, to lock the turntable 8. 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, but is Since the stopper main body 43 is received by the stopper body 43 in a decelerated state by the action, a dangerous situation in which the transferred object W moves and shifts due to the reaction when the turntable 8 rotates in the forward direction by 90 degrees and stops is avoided.

  By the above-described series of operations, the transported object support 9 on the turntable 8 of the forward traveling transporting body 1 stopped at the first fixed stop position rotates in the forward direction by 90 degrees, and the transported object support 9 The length direction of the transported object W supported above becomes a right angle sideways direction rotated by 90 degrees in the forward direction. From this state, the cylinder unit 37 of the turntable rotation driving means 32 at the first fixed stop position is actuated to return the band-shaped movable table 36 to the original retracted position, and the movable body 39 is rotated on the turntable 8 side. The rotation driven unit 13 (the roller 31 a) is relatively moved out of the groove 39 a of the movable body 39 by moving the driven unit 13 laterally away from the driven unit 13, and the transporting unit lock unit 34 is provided. By opening the pair of holding pieces 48a and 48b to release the lock on the transporting traveling body 1, the transporting traveling body 1 stopped at the first fixed stop position can be moved forward. As a result of the band-shaped movable base 36 returning to the retracted position in the lateral direction, the movable base 39 separated from the rotation driving driven part 13 on the turntable 8 side is returned to the retreat limit position by the cylinder unit 40.

  As described above, the turntable 8 of the transporting traveling body 1 stopped at the first fixed stop position is moved to 90 by using one of the rotation driving driven members 13 and 14 among the rotation driving driven members 13 and 14. The transported object W is transported in a state where the length direction of the transported object W supported on the transported object support table 9 is switched to the right angle sideways direction rotated by 90 degrees in the forward direction. Can be conveyed from the first fixed stop position to the lower side by the traveling body 1, but on the lower side from the first fixed stop position, the second fixed stop for the additional 90-degree rotation of the turntable in the forward direction. If the position has been set and the transporting vehicle 1 has stopped at the second fixed stop position, the transporting vehicle locking means 34 at the second fixed stop position is operated to operate the transporting vehicle 1. At the second fixed stop position. As shown in FIG. 12A, the turntable rotation driving means 32 at the second fixed stop position stops at the second fixed stop position because the band-shaped movable base 36 is at the retracted position and the movable body 39 is at the retreat limit position. The driven part 14 for rotation drive on the turntable 8 side of the transporting traveling body 1 is located to the side of the concave groove 39a of the movable body 39. In this state, by moving the band-shaped movable base 36 to the operation position by the cylinder unit 37, the movable body 39 at the retreat limit position moves closer to the rotary drive driven part 14 on the turntable 8 side, and the movable body 39 moves. The rotation driving driven portion 14 (the roller 31b) on the turntable 8 side relatively fits into the concave groove portion 39a of the body 39.

  In this state, similarly to the turntable unlocking means 33 and the turntable rotation driving means 32 at the first fixed stop position, as shown in FIG. Switching the lock lever 25 of the turntable lock means 15 to the release position, and moving the movable body 39 of the turntable rotation drive means 32 from the retreat limit position to the forward limit position in a state where the lock of the turntable 8 is released. Accordingly, the turntable 8 can be further rotationally driven in the forward direction by 90 degrees via the rotationally driven driven portion 14 (the roller 31b) fitted into the concave groove portion 39a of the movable body 39. Also at this time, the movable body 39 is stopped by the function of the buffer damper 44 of the stopper means 42 without any impact on the stopper body 43 at the forward limit position, so that the movable body 39 is supported on the turntable 8 via the transferred object support 9. There is no need to cause a shift in the supported transferred object W. When the turntable 8 is additionally rotated by 90 degrees in the forward direction, the locking concave portion 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 position. The locking lever 25 of the turntable locking means 15 is switched to the operating position, and the locking roller 26 is moved to the locking recess 19 of the guide member 16 in the same manner as in the operation at the first fixed stop position. The turntable 8 can be locked by being fitted. Thereafter, the band-shaped movable base 36 of the turntable rotation driving means 32 is returned to the retracted position in the horizontal direction, and the rotationally driven driven part 14 on the turntable 8 side is moved from within the concave groove 39a of the movable body 39 at the forward limit position. At the same time, the movable body 39 is moved backward to the original backward limit position.

  As described above, at the second constant stop position, the turntable 8 rotated in the forward direction by 90 degrees at the first constant stop position is further rotated by 90 degrees in the same direction. The length direction of the transported object W supported on the table 9) is 180 degrees reversed from the direction of the turntable 8 when traveling toward the first fixed stop position, and the second fixed stop position. The transported object W supported on the transporting traveling body 1 that travels poorly from above is transported in an opposite state in which the longitudinal front end is located at the rear end side of the transporting traveling body 1. Become.

  Lower than the second fixed stop position, a third fixed stop position for rotating the turntable 8 on the transport traveling body 1 by 90 degrees in the reverse direction by 90 degrees, and further lower than the third fixed stop position, A fourth fixed stop position for additionally rotating the turntable 8 on the transporting traveling body 1 in the reverse direction by 90 degrees can be set. The retracted position of the movable body 39 of the turntable rotation driving means 32 disposed at the third constant stop position or the fourth constant stop position is set as the forward limit position on the belt-shaped movable table 36, and the transport traveling body 1 Is locked at the third fixed stop position, the rotation driving driven part 14 of the two rotation driving driven parts 13 and 14 of the transporting traveling body 1 on the turntable 8 side turns the turntable rotationally. The movable member 39 is positioned at the side of the movable body 39 waiting at the forward limit position of the means 32. Therefore, after the transporting vehicle 1 is stopped and locked at the third fixed stop position, when the belt-like movable base 36 of the turntable rotation driving means 32 is moved to the operation position by the cylinder unit 37, the belt-like movable base 36 The movable body 39 waiting at the forward end position moves closer to the rotary drive driven portion 14 on the turntable 8 side, and the rotary drive driven portion 14 fits into the concave groove 39a of the movable body 39. Become.

  In this state, the turntable lock release means 33 is operated to switch the lock lever 25 of the turntable lock means 15 to the lock release posture, and then the movable body 39 is moved from the forward limit position to the backward limit position by the cylinder unit 40. By this, the turntable 8 rotates 90 degrees in the reverse direction from the state shown in FIG. 12B to the state shown in FIG. 12A, and the transferred object W supported by the transferred object support 9 moves from the first fixed stop position to the first fixed stop position. It is returned to the right-angled horizontal state when transported to the fixed stop position. Also at this time, by the function of the buffer damper 60, a dangerous situation in which the transferred object W moves together with the transferred object support table 9 can be avoided.

It is possible to return to the initial state, that is, the initial state when the article W is being conveyed toward the first fixed stop position.

  That is, the turntable rotation drive means 32 provided at the fourth fixed stop position also retracts the movable body 39 of the turntable rotation drive means 32, similarly to the turntable rotation drive means 32 provided at the third fixed stop position. The position is a forward limit position on the belt-shaped movable base 36. When the transport traveling body 1 is stopped and locked at the fourth fixed stop position, the two positions of the transport traveling body 1 on the turntable 8 side are set. The rotational drive driven part 14 of the rotational drive driven parts 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. The turntable 8 is turned 90 degrees in the reverse direction from the state shown in FIG. 12A to the first state shown in FIG. Rotate the orientation of the objects to be conveyed W supported by the object to be conveyed support 9 on the turntable 8, the front end can be restored to the initial state facing the front end side of the conveying traveling body 1.

  In the above description, on the transporting traveling body 1 traveling toward the first fixed stop position, the transported object W is in a forward-facing state in which the longitudinal front end is located on the front end side of the transporting traveling body 1. The direction of the transferred object W is rotated 90 degrees in the forward direction at the first fixed stop position and switched to the right angle sideways direction, and further rotated 90 degrees in the forward direction at the next second fixed stop position to be turned in the opposite direction. And at the third constant stop position, rotate 90 degrees in the reverse direction and switch back to the original right angle sideways again, and at the final fourth constant stop position, rotate further 90 degrees in the reverse direction to switch back to the original forward direction. As described above, this description only describes how to use the turntable rotation driving means 32 provided at each fixed stop position, and in fact, from the first fixed stop position to the fourth fixed stop position. Any of the fixed stop positions or these turntables At the fixed stop position for loading and unloading the transferred object set separately from the fixed stop position for the rotation operation, the transferred object W can be unloaded and loaded on the transferred object support 9 on the turntable 8. . In other words, the switching of the direction of the turntable 8 (conveyed object support table 9) at each fixed stop position can be performed by loading / unloading the conveyed object on / from the transporting traveling body 1 or performing an operation on the conveyed object W being transported. It will be done in connection. The work on the transferred object W supported and transferred on the transferred object support table 9 on the turntable 8 and the unloading operation of the transferred object W on the transferred object support table 9 on the turntable 8 include: It can be performed by an operator.

  Incidentally, the present invention relates to a turntable locking means on the transporting traveling body and a turntable lock release means on the fixed stop position side, wherein the turntable is set on the traveling route of the transporting traveling body. The setting of the fixed stop position of the transporting traveling body for rotationally driving the rotary table, the rotation angle and the rotating direction of the turntable at each fixed stop position, and the like are not limited to those described in the above embodiment.
