Description

The present invention relates to a mechanical parking installation comprising a stop adjustment equipment to stop the elevator for raising and lowering the carriage.

  Conventionally, three-dimensional warehouses and mechanical parking facilities, etc., are moved up and down by means of a rope (“cord” in this specification and claims refers to “wire rope”, “chain”, etc.) An elevator that drives the elevator to be moved up and down is provided. This elevator lifts / lowers a cord-like body to hold the elevator body at a desired height, and loads / unloads luggage and vehicles.

  For example, in the case of an elevator parking facility that is an example of a mechanical parking facility, a transporter (elevating body) that transports a pallet on which a vehicle is mounted to a predetermined storage shelf is provided, and the transporter is suspended by a cable-shaped body. The rope-like body is moved up / down to be moved to a desired storage shelf position. As an elevator which winds up / down the hoisting and lowering the cord-like body, there is a hoisting / rolling-down type using a driving motor to wind / lower the cord-like body.

  And after moving a carrier to the position of a desired storage shelf by the hoisting / lowering of a cord-like body and hold | maintaining to the parking equipment side, carrying in / out of a pallet is performed between storage shelves. Also in the case of the above-described three-dimensional warehouse, the lifting / lowering body is moved to the position of a desired storage shelf by winding / lowering the cord-like body, and then the cargo is carried in / out of the storage shelf.

  As a prior art of this type, for example, a swinging member that drives four corners of a transporter moved to a desired storage shelf position by winding / lowering a cord (wire) with an individual linear actuator. Is held on the storage shelf side (parking equipment side), and the end plate of the cable (wire) moving downward from the held carrier is detected by the sensor to stop the descending of the cable (For example, refer to Patent Document 1).

JP-A-7-166732

  However, in the case of the above prior art, since the sensor detects the lowering of the end plate provided at the end of the cord (wire), the load acting on the cord at the time of stoppage is subject to load fluctuation (pallet If the load changes due to, for example, loading / unloading, it is difficult to control the load acting on the cable so that it does not rise from the storage shelf side, and the carrier is held stably. It is difficult.

  In addition, due to the secular change of the cable-like body, the amount of expansion and contraction of the cable-like body changes due to the load change acting on the cable-like body, creating a step between the transporter and the storage shelf, and smooth dispensing / retraction is achieved. There is a risk of damage.

  Furthermore, it is possible to adjust the load acting on the cord at the time of stopping using a timer, but in that case, the load is indirectly adjusted by the time, so the load state and secular change When the ascending / descending speed fluctuates according to the above, there is a possibility that it cannot be adjusted to a predetermined load. In addition, the operation of converting “load” into “time” is required, and control is difficult.

Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. In the following embodiments, an elevator parking facility (FIG. 7) will be described as an example of a mechanical parking facility provided with a stop adjustment device. Further, in this embodiment, "Wai to do-loop" (hereinafter, simply referred to as "ropes 62") as a wick member is described as an example. In addition, the concept of the front-back / left-right direction in the document of this specification and a claim shall correspond with the concept of the front-back / left-right direction in the state which went to the elevator type parking equipment 50 shown in FIG.

  As shown in FIGS. 1 and 2, the stop adjustment device 1 of this embodiment is a horizontal beam (fixed-side support portion) of a steel structure constituting a parking tower 51 of a parking facility 50 (FIG. 7) that is a fixed structure portion. A cord-like support 2 is provided at 57. The horizontal frame 57 is fixed with the fixed frame 3 of the cord support 2.

  The fixed frame 3 is fixed to the upper plate 4, the side plate 5 that extends downward from the left and right positions of the upper plate 4, the back plate 6 that connects the left and right side plates 5, and the back plate 6 and the lower portion of the side plate 5. And a lower plate 7. The upper plate 4 is fixed to the horizontal beam 57 with bolts and nuts.

  A through hole 8 is provided at the center of the lower plate 7. The through hole 8 is formed in a size that allows the cord-like member 10 that supports the end of the rope 62 that is the cord-like body to enter. The end of the rope 62 is suspended from the connection fitting 11 supported by the cord-like member coupling member 10. In addition, a fixed-side support member 12 is provided at the center of the upper surface of the lower plate 7. The fixed side support member 12 is provided with a guide hole 13 at the center, and is fixed to the lower plate 7 with bolts and nuts 14.

  A shaft member 18 extending upward is provided at the center of the cord-like member 10. The shaft member 18 is inserted into the guide hole 13 of the fixed side support member 12, and a movable side support member 15 is provided at the upper end. The movable side support member 15 of this embodiment is attached to the end portion of the shaft member 18 by a nut 17 that is screwed into a screw portion 16 provided at the upper end of the shaft member 18.

  A support spring (compression spring) 20 that is an elastic body is provided between the fixed support member 12 and the movable support member 15. The support spring 20 is held between the upper surface of the fixed support member 12 and the lower surface of the movable support member 15.

  A hollow portion of the support spring 20 is provided with a guide hole 22 through which the shaft member 18 is inserted, and a cylindrical stopper member 21 having an outer diameter slightly smaller than the inner diameter of the support spring 20 is provided. ing. In this embodiment, the stopper member 21 is fixed to the upper surface of the stationary support member 12.

  The stopper member 21 has an outer diameter slightly smaller than the inner diameter of the support spring 20 so as to have a predetermined gap from the inner diameter of the support spring 20 so as to prevent buckling when the support spring 20 contracts. I have to. Further, by setting the height of the stopper member 21 to a predetermined height, the contraction of the support spring 20 is limited by a predetermined amount. Further, the stopper member 21 guides the shaft member 18 inserted into the guide hole 13 of the stationary support member 12 by the guide hole 22 so as to move in the axial direction of the rope 62.

  Further, as shown in FIG. 3, a detent member 25 that prevents the cord-like member coupling member 10 from rotating is provided below the fixed-side support member 12. The anti-rotation member 25 is fixed to the fixed-side support member 12 from the lower surface with a bolt portion 26, and the lower portion is inserted into a through hole 27 provided in the cord-like member coupling member 10. By this rotation preventing member 25, the cord-like member coupling member 10 is turned in the horizontal direction by the rotation generated when the helical shape of the support spring 20 (compression spring) is compressed or the rotation caused by the tension generated when the rope 62 is a stranded wire. The rope 62 can be moved straight in the axial direction by preventing the fluctuation of the spring constant of the support spring 20 and the malfunction of the detection unit 30 described later.

  Therefore, the load of the transporter (elevating body) 54 acting on the rope 62 is supported by the support spring 20 that supports the movable support member 15 provided at the upper end of the shaft member 18 via the cord-like member 10. When the support spring 20 contracts, the stopper member 21 contracts the support spring 20 in the axial direction of the rope 62 without deforming the support spring 20 in the lateral direction. In this embodiment, since the support spring 20 is a compression spring, the stopper member 21 prevents a buckling phenomenon that occurs when a compression spring having a large slenderness ratio (elongated) is used.

  In addition, when the load acting on the rope 62 is large, even if the movable support member 15 provided at the upper end of the support spring 20 is in contact with the upper surface of the stopper member 21 and the load acting on the transporter 54 changes. The load acting on the rope 62 is always supported on the fixed side (horizontal beam 57) via the fixed frame 3, and the transporter 54 can be stably supported.

As shown in FIGS. 1 and 2, a detection unit that detects that the load acting on the rope 62 has decreased between the fixed frame 3 of the cord support unit 2 and the cord connection member 10. 30 is provided. The detection unit 30 protrudes downward from the fixed frame 3 and is bent toward the cord-like member coupling member 10, a proximity switch 32 provided on the support plate 31, and the proximity switch 32. And the detection plate 33 provided on the cord-like member coupling member 10 so as to be located on the front surface. The proximity switch 32 provided on the support plate 31 is disposed so as to face the opening 34 of the detection plate 33 provided on the cord-like member coupling member 10. Supporting plate 31, with screws 38 serves to allow vertical adjustment of the fixing position, so the relative position of the proximity switch 32 and the detection plate 33 by adjusting the position of the support plate 31 is cut with adjustment Yes.

Further, in this embodiment, even if the proximity switch 32 does not operate due to a failure or the like, a limit switch 35 is provided that detects that the detection plate 33 has moved up beyond the detection position of the proximity switch 32. The limit switch 35 is provided on a support plate 37 projecting downward from the fixed frame 3 and has a detection rod 36 projecting toward the opening 34 of the detection plate 33. The detection rod 36 does not operate in a state where the transporter 54 is suspended or stopped by the proximity switch 32, but when the lower end of the opening 34 of the detection plate 33 rises to the position of the detection rod 36, this limit The switch 35 is activated to stop the elevator 60. The limit switch 35 prevents the load acting on the rope 62 from becoming too small. The support plate 37 also serves to allow vertical adjustment of the fixing position by screws 38, so cut with a relative position adjustment of the limit switch 35 and the detection plate 33 by adjusting the position of the support plate 37 ing.

As shown in FIGS. 4 (a) to 4 (c), according to the stop adjusting device 1, after the weight of the transporter 54 is supported on the fixed side at the position of the predetermined storage shelf 56, the rope is adjusted as follows. The elevator 60 (FIG. 7) can be stopped in a state where the load acting on 62 is reduced to a predetermined amount.

  As shown in FIG. 4 (a), the detection unit 30 supports the rope 62 when the weight of the carrier 54 or the weight of the pallet 80 and the vehicle V (FIG. 7) mounted on the carrier 54 is applied. The spring 20 contracts and is supported in a mechanical stop state (FIG. 1) in which the movable side support member 15 abuts against the stopper member 21. In this state, since the opening 34 of the detection plate 33 is positioned in front of the proximity switch 32, detection by the proximity switch 32 is not performed.

  Then, as shown in FIG. 4B, when the carrying device 54 is held at a predetermined position of the storage shelf 56 and then the suspended rope 62 is unwound, the load acting on the rope 62 is reduced. When the spring force of the support spring 20 exceeds the load acting on the rope 62, the detection plate 33 is moved upward together with the cord-like member 10 supporting the rope 62 by the spring force. As the detection plate 33 rises, the front surface of the proximity switch 32 is blocked by the detection plate 33, so that the transporter 54 is placed in the storage shelf 56 (a shelf-side receiving bracket 71 provided on a shelf column 58 in FIG. 9 described later). , 72), it is detected that the load acting on the rope 62 has decreased to a predetermined amount. By the detection of the detection plate 33 by the proximity switch 32, the elevator 60 that suspends the transporter 54 is stopped.

That is, as shown in FIG. 4 (c), cord-shaped binding member 10, the movable-side support member 15 from the state of the most upper portion of the wick member coupling member 10 is in contact with the lower surface of the fixed-side supporting member 12 There has lifting stroke a to the state of the outermost lower portion in contact with the upper surface of the stopper member 21. The stroke A is a stroke B in which the proximity switch 32 detects that the load acting on the rope 62 has decreased to a predetermined load from the lowermost state where the movable support member 15 contacts the stopper member 21. In this position, as described above, when the proximity switch 32 cannot detect the failure due to the failure of the proximity switch 32, the limit switch 35 has a stroke C for detecting the load reduction of the rope 62. In FIG. 4 (c), the stroke D at which the cord-like member 10 is brought into contact with the lower surface of the fixed-side support member 12 when the cord-like support 2 is assembled is also shown at the top. ing. In FIG. 4 (c), the detection of the stroke B and the stroke C is shifted, but it is configured to detect continuously.

  For example, in the state shown in FIG. 4 (b), as shown in FIG. 5, the load applied to the rope 62 becomes a predetermined load that balances the spring force of the support spring 20, as shown in FIG. The descent is stopped and the descent of the transporter 54 is stopped. In this state, the load acting on the rope 62 is balanced with the spring force of the support spring 20, so that the rope 62 is prevented from loosening after the transporter 54 is held by the storage shelf 56, and the rope 62 A predetermined tension can be maintained. That is, the movable side support member 15 to which the end portion of the rope 62 is connected is separated from the stopper member 21 and supports the rope 62 with the tension due to the spring force of the support spring 20. Thereby, the tension | tensile_strength of the rope 62 can be maintained in a preferable state, and when the carrier 54 hold | maintained with the storage shelf 56 is raised again, it can raise smoothly.

  In addition, since the spring constant of the support spring 20 can be manufactured with a certain accuracy and generally does not change with time, by incorporating the stopper member 21 that has been processed to a predetermined length in advance, the rope 62 in the detector 30 can be easily adjusted. The load reduction amount detection can be matched with a preferable load of the rope 62 when the elevator 60 is stopped.

  The state shown in FIG. 5 is the state shown in FIG. 4B. In the state where the detection plate 33 blocks the front surface of the proximity switch 32 and the elevator 60 is stopped as described above, the movable support member 15 is The load acting on the rope 62 is a state separated from the stopper member 21 and is determined by the spring constant of the support spring 20 and the like due to the spring force of the support spring 20. Therefore, the load acting on the rope 62 in a state where the transporter (elevating body) 54 is held at the position of the predetermined storage shelf 56 can be made almost constant without being affected by the load on the transporter side. Moreover, since the spring constant of the support spring 20 has very little secular change, load change due to secular change can also be suppressed.

  In this embodiment, the stopper member 41 is provided with a buckling prevention portion 42 having a predetermined gap and an inner diameter of the support spring 20 so as not to buckle when the support spring 20 contracts. A shaft portion 43 formed with a diameter guided in the guide hole 13 of the support member 45 is provided.

  The connection fitting 11 to which the end portion of the rope 62 is connected is supported by a cord-like member coupling member 44 provided on the shaft portion 43 of the stopper member 41. Thereby, the stopper member 41 moves in the axial direction integrally with the rope 62.

  A movable support member 46 is integrally provided on the opposite side of the stopper member 41 from the shaft portion 43. The movable support member 46 is integrally formed on the upper portion of the buckling prevention portion 42 so that the upper end of the support spring 20 is locked. The support spring 20 is provided between the movable side support member 46 and a spring seat formed on the upper surface of the fixed side support member 45.

  Therefore, in this embodiment, when the load acting on the rope 62 is large, the lower surface of the buckling prevention portion 42 of the stopper member 41 is in contact with the upper surface of the fixed support member 45 and acts on the rope 62. Even when the load changes, the load acting on the rope 62 is always supported by the fixed frame 3 via the stopper member 41, and the transporter 54 can be stably suspended.

  In addition, according to this embodiment, the buckling prevention portion 42 of the stopper member 41 provided in the hollow portion of the support spring 20 prevents the support spring 20 from being laterally deformed when the support spring 20 contracts, thereby supporting the support spring 20. The spring 20 can be contracted in the axial direction of the rope 62.

  Since the other configurations and the operations shown in FIGS. 4A to 4C are the same as those of the stop adjustment device 1 of the first embodiment described above, detailed description thereof is omitted.

Thereafter, in this state, the transporter 54 is lowered at a slow speed and is held at a predetermined position on the storage shelf 56 by the fixed position holding device 70. Thereby, the load of the transporter 54 is held by the fixed position holding device 70.

  Further, the load acting on the rope 62 is gradually reduced by the further lowering operation of the transporter 54 by the elevator 60, and the load acting on the rope 62 is provided in the cord support portion 2 of the stop adjusting device 1. When it becomes smaller than the spring force of the support spring 20, the movable support member 15 is raised by the spring force of the support spring 20 (state of FIG. 5).

  As the movable support member 15 is pushed up by the support spring 20, the cord-like member coupling member 10 to which the end of the rope 62 is coupled and the detection plate 33 provided on the cord-like member coupling member 10 are integrated. And the front surface of the proximity switch 32 is blocked by the detection plate 33. Then, the detection of the detection plate 33 by the proximity switch 32 determines that the load acting on the rope 62 has decreased to a predetermined amount, and the elevator 60 is stopped.

  Thus, according to the elevator type parking facility 50 provided with the stop adjusting device 1, during normal operation, the weight of the transporter 54 and the large weight when the pallet 80 and the vehicle V are mounted on the upper part thereof are It is supported by the fixed support member 12 through the cord-like member coupling member 10 connected to the end, the shaft member 18 and the stopper member 21.

  In other words, even if the load acting on the rope 62 differs greatly between when the pallet 80 moved up and down by the transporter 54 is an empty vehicle and when it is a real vehicle, even when there is no load when the pallet 80 is not mounted on the transporter 54, Then, the movable side support member 15 is used in a state in which the support spring 20 is contracted and in contact with the stopper member 21.

  When the transporter (elevating body) 54 is held at the position of the predetermined storage shelf 56, the load acting on the rope 62 decreases after the weight of the transporter 54 is supported by the fixed support member 12 and reaches a predetermined amount. Since the support spring 20 is extended and the proximity switch 32 detects the detection plate 33, the load acting on the rope 62 with the transporter 54 held by the storage shelf 56 is the spring constant of the support spring 20 or the like. By setting this, the load acting on the rope 62 in the holding state of the transporter 54 can always be kept at a stable load.

  Therefore, even if the load acting on the rope 62 changes due to secular change or the like, the load acting on the rope 62 can always be made almost constant by the spring force of the support spring 20, and the elevator 60 is stopped. The rope 62 suspending the transporter 54 can be in a state where a predetermined load is always applied without being slackened, and the transporter (elevating body) 54 can always be stably driven up and down.

  In addition, the configuration in which the elevator 60 is stopped in a state where a predetermined load is applied to the rope 62 can be a simple configuration (for example, a complicated mechanism for forcibly constraining is not required), and the detection can be performed. Since the part 30 can be configured simply as ON / OFF, the reliability of the stop adjustment device 1 that stops the elevator 60 in a state where a predetermined load is applied to the rope 62 and the maintenance performance are improved. Is possible.

  In the above embodiment, a mechanical parking facility has been described as an example of the facility including the stop adjustment device 1 for the elevator 60. However, the present invention can be similarly applied to any facility including an elevator that lifts and lowers the elevator. The same applies to equipment.

  In the above-described embodiment, the lower drive type elevator parking facility 50 has been described as an example. However, the mechanical parking facility may be any parking facility that lifts and lowers the transporter 54 with a rope-like body (rope, chain, etc.). An upper drive system or other types of mechanical parking equipment may be used, and the present invention is not limited to the above embodiment. Furthermore, although the elevator-type parking equipment 50 example in which the transporter 54 has become the suspension method of the moving pulley system has been described, the suspension method for raising and lowering the transporter 54 is not limited to the above-described embodiment, There may be. The fixed position holding device 70 may be another type.

  Moreover, although the said embodiment demonstrated the example which provided the rope support part 2 of the elevator 60 in the parking tower 51 which is a fixed structure part, it seems that the rope support part 2 is provided in the carrier (elevator) 54. Alternatively, the cord-like support 2 may be provided on either the fixed structure or the lifting body, and is not limited to the above embodiment.

  Furthermore, the said embodiment has shown an example, The various change in the range which does not impair the summary of this invention is possible, and this invention is not limited to the said embodiment.
