Description

The present invention relates to a traversing device for traversing a pallet and a mechanical parking facility equipped with the traversing device.

Conventionally, in some mechanical parking facilities and the like, the pallets are traversed in a predetermined traversing step. An example of this is a mechanical parking facility that has multiple rows and multiple stages of storage positions and moves pallets between these storage positions.

As a prior art of this type, there is a mechanical parking facility equipped with a loading / unloading lift that raises / lowers a pallet for loading / unloading an automobile to / from a storage shelf at the loading / unloading section (see, for example, Patent Document 1). This mechanical parking facility is equipped with a swing-type traversing device provided with a guide roller that supports a guide frame (trailing rail) of a pallet that is lowered by a loading / unloading lift. In this traversing device, a movable frame provided with a guide roller is swung so that the guide roller is arranged at a support position or retracted from the support position.

Further, as another prior art, there is an underground multi-stage parking facility in which a pallet stored underground is moved laterally from the warehousing / delivery section (see, for example, Patent Document 2). In this parking facility, swingable flaps are provided on the lower surfaces of all traversing pallets, and the flaps are supported by the rollers of the traversing device in a horizontally overhanging state and traversed.

However, in the traversing device of Patent Document 1, the position of supporting the movable frame and the position of the guide roller are swung in an arc shape. Therefore, when the guide roller is arranged at the support position or retracted from the support position, the distance for releasing the pallet upward becomes large. Therefore, the operation time for moving the pallet becomes long.

In addition, the height of the advancing / retreating device that swings the movable frame is required. For this reason, in the case of a layout in which a vehicle that allows vehicles to enter and leave the pallet passes below the traversing device, such as above the warehousing / delivery section, a height dimension for arranging the traversing device is required in addition to the height dimension that the vehicle passes through. become. Therefore, the height dimension of the mechanical parking facility becomes high.

Further, in the case of Patent Document 2, it is necessary to equip all the traversing pallets with a mechanism for swinging the flap. Therefore, the traversing pallet is costly and it is necessary to supply power to the traversing pallet. In addition, when lowering the traverse pallet, in order to swing and store the flap provided at the bottom of the traverse pallet, it is necessary to release the traverse pallet to a position far away from the traverse device, and the traverse pallet is moved. Because of the longer operating time.

Therefore, an object of the present invention is to provide a traversing device capable of suppressing a height dimension at which a pallet escapes when the traversing drive unit advances and retreats, and a mechanical parking facility equipped with the traversing device.

In order to achieve the above object, the traversing device according to the present invention is a traversing device arranged on a hoistway of a pallet and traversing the pallet in a predetermined stage, and is a traversing drive that supports the pallet from below and traverses. A unit, an advance / retreat drive unit that advances the traverse drive unit to the hoistway or retracts it from the hoistway, and a guide unit that regulates the advance / retreat operation of the traverse drive unit when the traverse drive unit advances or retreats by the advance / retreat drive unit. When the pallet is moved up and down, the traverse drive unit is retracted from the hoistway, and when the pallet is traversing, the traverse drive unit is advanced to the hoistway and controlled to support the pallet. The advance / retreat drive unit is configured to advance / retreat the traverse drive unit in the horizontal direction by rotational power.

With this configuration, the traverse drive unit arranged in the hoistway of the pallet or retracted from the hoistway can be moved forward and backward in the horizontal direction. Therefore, it is possible to suppress the height dimension in which the pallet is released when the traverse drive unit is advanced or retracted. Moreover, the height dimension of the traversing device can be kept low.

Further, the advancing / retreating drive unit includes a drive unit that generates the rotational power and a horizontal movement mechanism that moves the traverse drive unit horizontally along the guide unit by the rotational power of the drive unit. You may.

With this configuration, the transverse drive unit of the transverse device is moved in the horizontal direction via the horizontal movement mechanism by the rotational power of a drive such as a motor that generates rotational power, so that the height dimension of the transverse device is kept small. be able to.

Further, the horizontal movement mechanism is provided in the arm member rotated by the drive machine, a cam member rotated by the arm member at a position separated from the drive machine by a predetermined distance, and the traverse drive unit. It may be composed of a groove cam mechanism having a groove portion with which the cam member is engaged.

With this configuration, by rotating the link portion with the drive machine, the cam member provided in the link portion moves along the groove portion of the transverse drive portion. As a result, the traverse drive unit guided by the guide unit can be horizontally moved. Therefore, the height dimension of the traversing device can be kept small.

Further, the arm member may be configured so that the axis of the cam member can be rotated in a horizontal direction with a rotation angle of 180 ° or more with respect to the axis of the drive machine.

With this configuration, even if a load acts in the direction of advancing or retracting the traverse drive unit while the traverse drive unit is retracted or advanced, a force acts in the direction of blocking the movement of the groove portion by the cam member. Therefore, it is possible to prevent the arm member from moving in the advancing direction.

Further, the groove cam mechanism is configured as a suspension type in which the arm member is rotated downward by the drive machine, and the arm member is the cam member in a state where the traverse drive portion is retracted. It may be provided with an urging means for urging in the direction of the end of the groove. As the urging means for urging the cam member toward the end of the groove, the means for urging the cam member toward the end of the groove by manipulating the position of the center of gravity of the arm member, and the means for urging the cam member toward the end of the groove with a spring. Includes means of encouraging, etc. Further, the "end direction of the groove portion" means a direction opposite to the direction in which the cam member moves when the traverse drive portion starts advancing and retreating.

With this configuration, in a configuration in which the cam member is rotated downward by the arm member, even if the drive machine and the power transmission unit fail, the traverse drive unit can be prevented from advancing and retreating by the urging means.

On the other hand, the mechanical parking facility according to the present invention has at least two rows and two stages of storage space, and the pallet on which the automobile to be loaded and unloaded from the warehousing / delivery section is mounted is moved up and down and traversed between the storage spaces to store the pallet. This is a mechanical parking facility in which a predetermined stage is configured as a traversing stage, and the traversing stage is equipped with any of the traversing devices.

With this configuration, the height of the pallet retracted when the pallet is supported by the traversing drive unit of the traversing device is lowered, and the height of the mechanical parking facility can be suppressed. Moreover, the operation time for mounting or dismounting the pallet on the traversing device can be shortened, and the pallet can be smoothly moved.

In addition, it is a mechanical parking facility that has at least two rows and two stages of storage space, and stores the pallet that mounts an automobile that enters and exits from the warehousing / delivery section by moving it up and down between the storage spaces. The upper stage of the entry / exit unit is configured as a traverse stage, and the advance / retreat drive unit of the traverse device in the upper stage of the entry / exit unit includes the traverse device according to any one of claims 3 to 5. The groove cam mechanism is configured so that the arm member is rotated downward by the drive machine to advance and retreat the traverse drive unit.

With this configuration, it is possible to suppress the downward protrusion amount of the traversing device provided above the warehousing / delivery section and secure the height dimension in the warehousing / delivery section. Therefore, the height dimension can be suppressed even in a mechanical parking facility having a warehousing / delivery section below the traverse step.

According to the present invention, it is possible to keep the height dimension at which the pallet escapes low when advancing and retreating the traversing drive unit of the traversing device that traverses the pallet. Therefore, it is possible to operate the traversing device efficiently and move the pallet quickly.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following embodiment, a mechanical parking facility 1 having a storage space 8 having four stages and three rows will be described as an example. The concept of the vertical and horizontal directions in this specification and the documents of the claims shall be consistent with the concept of the vertical and horizontal directions in the state facing the mechanical parking facility 1 shown in FIG. In addition, each stage may be called a "floor".

(Structure of mechanical parking equipment)
The mechanical parking facility 1 will be described with reference to FIG. The mechanical parking facility 1 of this embodiment is a partially underground type in which up to the second floor is arranged underground. The mechanical parking facility 1 includes a pillar 2 vertically provided at a front-rear position, a front-rear beam material (not shown) connecting the pillars 2 in the front-rear direction, and a left-right beam material (not shown) connecting the pillars 2 in the left-right direction. ) Is provided. The mechanical parking facility 1 includes the first row F1 at the bottom, the second F2, the third F3, the fourth F4 at the top, the first row L1 at the left end row, and the second row L2 at the center. It is a multi-column multi-stage system having a storage space 8 of 4 columns × 3 columns, which is the third column L3 of the right end column. In each row of the first row L1 to the third row L3, the vertical space in which the pallet 100 moves up and down is the hoistway 9. In the mechanical parking facility 1 of this embodiment, the third stage F3 is the entry floor of the ground G, and the first row L1 is the entry / exit section 6. A front movable fence 7 that can be opened and closed in the vertical direction is provided on the front surface of the warehousing / delivery unit 6.

In each of the illustrated rows (1st row L1 to 3rd row L3), all the pallets 100 in that row are placed between the lowermost first stage F1 and the uppermost fourth stage F4 by the elevating drive unit 10. Can be raised and lowered together (simultaneously) as shown by the arrow H. The elevating drive unit 10 hooks a locking member (not shown) provided on each pallet 100 to a locking hook (not shown) of an elevating chain 12 that rotates via a drive shaft 13 that is rotationally driven by an elevating motor 11. It is designed to move up and down.

Then, in the first stage F1 which is the lowermost stage and the fourth stage F4 which is the uppermost stage shown in the drawing, each pallet 100 can be traversed individually as indicated by an arrow W. The first stage F1 is the lower traverse stage, the fourth stage F4 is the upper traverse stage, and these are predetermined stages that can be traversed. The traversal of each pallet 100 is carried out by the traversing drive units 21 and 31 (the description of the traverse drive unit of the first stage F1 is omitted) described later, so that each pallet 100 is arranged in one row between the first row L1 and the third row L3. It is possible to make it rampant every time. The traversing operation of each pallet 100 may be a sequential operation for each column or a simultaneous operation for a plurality of columns.

In the mechanical parking facility 1 of this embodiment, the fourth stage F4 of the upper traversing stage is provided with the second traversing device 30 in a portion adjacent to the upper part of the warehousing / delivery unit 6 of the first row L1. The first traversing device 20 is provided in L2 and L3 in the third column. By equipping the fourth stage F4, which is the upper stage of the warehousing / delivery unit 6 of the first row L1, with the second traversing device 30, the height T2 from the pallet 100 to the second traversing device 30 in the warehousing / delivery unit 6 can be increased by 2. The height from the pallet 100 to the first traversing device 20 in the row L2 and the third row L3 is higher than the height T1.

Further, when the pallet 100 is supported by the first traversing device 20 and the second traversing device 30 provided in the fourth step F4 of the upper traversing step, the traversing drive units 21 and 31 (the portion that supports and traverses the pallet 100) once. Is retracted from the hoistway 9. After that, after moving the pallet 100 upward, it is necessary to advance the traversing drive units 21 and 31 to the hoistway 9 and then mount and support the pallet 100. Therefore, the traversing devices 20 and 30 of the fourth stage F4 have a function of advancing and retreating the traversing drive units 21 and 31 to the hoistway 9 or retracting from the hoistway 9. The traversing device 40 in the first stage F1 of the lower traversing stage in this embodiment does not have an advancing / retreating function. Since the traversing device 40 of the first stage F1 may have the same configuration as the traversing drive unit 21 described below, detailed description thereof will be omitted.

The traversing devices 20, 30, 40 for traversing each of the pallets 100 and the elevating drive unit 10 for raising and lowering the pallets 100 in each row are driven and controlled by the control unit 5. The control unit 5 includes a processor, a volatile memory, a non-volatile memory, an I / O interface, and the like. The control unit 5 also controls the elevating position of the pallet 100 and the advance / retreat of the traversing drive units 21 and 31 of the first traversing device 20 and the second traversing device 30. According to the mechanical parking facility 1, the control unit 5 drives and controls the elevating drive unit 10 and the traversing devices 20, 30, 40, and elevates and traverses the pallet 100 on which the automobile V is mounted between the storage spaces 8. Let it move to the target position.

(Structure of the first traversing device)
The first traversing device 20 will be described with reference to FIGS. 2 to 7. As shown in FIGS. 2 and 3, the first traversing device 20 is provided with a traversing drive unit 21 above the beam member 22 fixed to the frame 3 of the mechanical parking facility 1. The beam member 22 is fixed to the frame body 3 on the left and right end faces. The beam member 22 is provided with slide rails 23 at the upper left and right positions. The slide rail 23 has a U-shaped cross section in which guide surfaces 23a are formed on the upper part and the lower part.

On the other hand, the transverse drive unit 21 has a support frame 24 extending in the left-right direction, a plurality of transverse rollers 25 provided on the support frame 24 at predetermined intervals, and a roller drive unit 26 for rotating the transverse roller 25. ing. The transverse roller 25 is rotatably supported by a support shaft 25a projecting laterally from the support frame 24. The roller drive unit 26 has a drive motor 26a provided in the lower part of the support frame 24 and a drive chain 26c driven by a sprocket 26b rotated by the drive motor 26a. By rotating the drive motor 26a, each transverse roller 25 is rotated by the drive chain 26c via the sprocket 25b provided on each transverse roller 25. The rotation of each traversing roller 25 causes the pallet 100 mounted on the upper portion to traverse (FIG. 1). As the pallet 100, for example, a rail member 101 is provided on the lower surface thereof, and the rail member 101 can be placed on the traversing roller 25 and traversed (FIG. 1). The portion that supports and traverses the pallet 100 from below is not limited to the rail member 101, and may be another portion such as under the tire running surface.

FIG. 4 is a perspective view of the first traversing device 20 viewed from diagonally above one side, and FIG. 5 is a perspective view of the first traversing device 20 viewed from diagonally above the other. The first traversing device 20 is provided with a traversing drive unit 21 above the beam member 22 fixed to the frame body 3. The traversing drive unit 21 has a support frame 24 extending in the left-right direction of the pallet 100, and a plurality of traversing rollers 25 provided on the support frame 24. The roller drive unit 26 that rotationally drives the transverse roller 25 is not shown. With such a traversing drive unit 21, the pallet 100 can be traversed by rotationally driving the traversing roller 25 after the rail member is placed on the traversing roller 25.

On the other hand, as shown in FIG. 6, the movement of the traversing drive unit 21 of the first traversing device 20 is restricted by the guide unit 27 so as to advance and retreat in the horizontal direction above the beam member 22. The guide unit 27 advances and retreats the traverse drive unit 21 in the horizontal direction along the slide rail 23. A bracket 27a is provided downward on the support frame 24 of the traverse drive unit 21. The bracket 27a is provided at a left-right position close to the slide rail 23. The bracket 27a is provided with a slide roller 27b so as to move in the front-rear direction along the guide surface 23a of the slide rail 23. As a result, the support frame 24 of the traverse drive unit 21 is restricted so that the slide roller 27b provided on the bracket 27a moves horizontally along the slide rail 23.

Then, as shown in FIG. 2, the first traversing device 20 is provided with an advancing / retreating driving unit 50 that advances / retreats the traversing driving unit 21 in the horizontal direction above the beam member 22. The advancing / retreating driving unit 50 is provided between the guide units 27 at the left and right positions for advancing / retreating the support frame 24 in the horizontal direction.

As shown in FIGS. 7A and 7B, the advancing / retreating driving unit 50 of the first traversing device 20 includes a driving machine 51 that generates rotational power. As the drive machine 51, an electric motor can be used. The advancing / retreating drive unit 50 includes a horizontal movement mechanism 52 that moves the traverse drive unit 21 in the horizontal direction by the guide unit 27 by the rotational power of the drive machine 51. The horizontal movement mechanism 52 has an arm member 53 that is rotated upward by the drive machine 51.

As shown in FIG. 3, the arm members 53 are provided at left and right positions, and they are connected by a connecting shaft 54. The connecting shaft 54 is supported by a support plate 22a projecting upward from the beam member 22. The connecting shaft 54 is rotatable by a bearing provided on the support plate 22a. A chain 51b is hung between the sprocket 51a provided on the drive machine 51 and the sprocket 54a provided on the connecting shaft 54. Therefore, by rotating the drive machine 51, the connecting shaft 54 is rotated in a predetermined direction.

The arm member 53 is formed in a curved portion 53a that protrudes unilaterally from a portion fixed to the connecting shaft 54 and whose tip portions are curved in opposite directions. An advancing / retreating roller 55, which is a cam member, is provided at the end of the curved portion 53a. The advancing / retreating roller 55 is provided so as to rotate at an axial center in the same direction as the axial center of the connecting shaft 54. By providing the curved portion 53a at the tip end portion of the arm member 53, the advancing / retreating roller 55 is arranged at a position separated from both ends of the connecting shaft 54 in the left-right direction. The advancing / retreating roller 55 has an axial center arranged at a position separated by a predetermined distance close to the axial center of the connecting shaft 54, and has a small turning radius. The cam member may be a non-rotating pin or the like in addition to the advancing / retreating roller 55.

On the other hand, as shown in FIG. 7A, the guide plate 56 is projected from the support frame 24 in the direction of the advancing / retreating roller 55. The guide plate 56 is provided with a groove portion 57 extending in the vertical direction. The advance / retreat roller 55 is engaged with the groove 57. Therefore, in the advancing / retreating drive unit 50 of this embodiment, the advancing / retreating roller 55 is rotated by a predetermined radius by the arm member 53 by rotating the connecting shaft 54 by the driving machine 51. In this way, the horizontal movement mechanism 52 is a groove cam mechanism 58 in which the advancing / retreating roller 55 moves along the groove portion 57, and the guide plate 56 provided with the groove portion 57 moves in the horizontal direction integrally with the support frame 24. ing. In the groove cam mechanism 58, the advancing / retreating roller 55 is a cam member.

Further, in the arm member 53, the center of the advancing / retreating roller 55 is rotated upward with respect to the rotation center of the arm member 53 at a rotation angle θ of 180 ° or more. Here, 180 ° or more includes, for example, setting a positive tolerance such as 180 ° −0 ° / + 4 ° or setting a reference value to a value exceeding 180 ° such as 185 °. Further, at least one of the angle on the arm rotation side formed by the line (virtual line) connecting the axis of the connecting shaft 54 and the axis of the advancing / retreating roller 55 and the groove center line of the groove portion 57 is set to be 90 ° or less. You may. By setting the rotation angle θ to 180 ° or more, even if a load is applied in the direction of advancing the traverse drive unit 21 in a state where the traverse drive unit 21 is retracted, the advance / retreat roller 55 moves toward the end of the groove portion 57. It is prevented that the arm member 53 is pushed and rotates in the advancing direction. The rotation angle θ of the arm member 53 can be changed by changing the height of the contact member 22c provided on the drive machine base 22b, adjusting the limit switch or encoder for detecting the stop position, or the like.

In this way, according to the advance / retreat drive unit 50, the arm member 53 is rotated by the drive machine 51 via the connecting shaft 54. As a result, the advancing / retreating roller 55 provided in the curved portion 53a at the tip of the arm member 53 moves along the groove portion 57 provided in the guide plate 56 of the support frame 24. Then, by the movement of the advancing / retreating roller 55, the slide roller 27b provided on the bracket 27a of the guide portion 27 is moved in the horizontal direction along the guide surface 23a of the slide rail 23. As a result, the traverse drive unit 21 is moved in the horizontal direction integrally with the support frame 24. The amount of movement S in the horizontal direction is approximately twice the turning radius of the advancing / retreating roller 55 provided on the arm member 53.

Therefore, the traverse drive unit 21 can be moved in the horizontal direction between the state of being advanced to the hoistway 9 and the state of being retracted from the hoistway 9 by the advance / retreat drive unit 50. Since the traversing drive unit 21 is moved forward and backward in the horizontal direction, the height of the first traversing device 20 can be suppressed. Therefore, according to the first traversing device 20, when the traversing drive unit 21 is retracted when the pallet 100 is moved up and down, the traversing drive unit 21 can be retracted if the pallet 100 is released slightly upward. This makes it possible to shorten the time for raising and lowering the pallet 100 and to move the pallet 100 quickly. Further, even when the pallet 100 is supported by the traverse drive unit 21, if the pallet 100 is slightly released upward from the traverse drive unit 21 with the traverse drive unit 21 retracted from the hoistway 9, the traverse drive unit 21 Can advance to the hoistway 9. Then, if the lifted pallet 100 is lowered and supported by the traverse drive unit 21, a series of operations can be performed quickly. As described above, according to the first traversing device 20, the pallet 100 can be quickly moved to the target position.

Further, according to the advance / retreat drive unit 50, the advance / retreat roller 55 is urged downward by the own weight of the advance / retreat roller 55 provided on the arm member 53 and the curved portion 53a at the tip thereof. Therefore, even if a failure occurs in the drive system (drive machine 51, chain 51b, etc.) that rotates the connecting shaft 54, the advance / retreat roller 55 does not move upward. That is, that state is maintained in both the retracted state and the advanced state of the traversing drive unit 21.

(Structure of the second traversing device)
The second traversing device 30 provided above the warehousing / delivery unit 6 will be described with reference to FIGS. 8 to 10. In the second traversing device 30, the traversing drive unit 31 is a hanging type. As shown in FIG. 8, the second traversing device 30 is provided with a traversing drive unit 31 below the beam member 32 fixed to the frame 3 of the mechanical parking facility 1. The beam member 32 is provided with slide rails 33 at the lower portions of the left and right positions. The slide rail 33 is formed in a U-shaped cross section having guide surfaces 33a formed in the upper part and the lower part.

On the other hand, as shown in FIG. 9, the traversing drive unit 31 rotates a support frame 34 extending in the left-right direction, a plurality of traversing rollers 35 provided on the support frame 34 at predetermined intervals, and the traversing roller 35. It has a roller drive unit 36 for driving. The transverse roller 35 is rotatably supported by a support shaft 35a projecting laterally from the support frame 34. The roller drive unit 36 has a drive motor 36a provided under the support frame 34 and a drive chain 36c driven by a sprocket 36b rotated by the drive motor 36a. By rotating the drive motor 36a, each transverse roller 35 is rotated by the drive chain 36c via the sprocket 35b provided on each transverse roller 35. The rotation of each traversing roller 35 causes the pallet 100 mounted on the traversing roller 100 to traverse (FIG. 1). As the pallet 100, for example, a rail member 101 is provided on the lower surface thereof, and the rail member 101 can be placed on the traversing roller 35 and traversed (FIG. 1).

On the other hand, the movement of the advancing / retreating drive unit 60 of the second traversing device 30 is restricted by the guide unit 37 so as to advance / retreat in the horizontal direction below the beam member 32. The guide unit 37 advances and retreats the traverse drive unit 31 in the horizontal direction along the slide rail 33. The support frame 34 of the transverse drive unit 31 is provided with a bracket 37a facing upward. The bracket 37a is provided at a left-right position close to the slide rail 33. The bracket 37a is provided with a slide roller 37b so as to move in the front-rear direction along the guide surface 33a of the slide rail 33. As a result, the support frame 34 of the traverse drive unit 31 is restricted so that the slide roller 37b provided on the bracket 37a moves horizontally along the slide rail 33.

Then, as shown in FIG. 8, the second traversing device 30 is provided with an advancing / retreating driving unit 60 that advances / retreats the traversing driving unit 31 in the horizontal direction below the beam member 32. The advancing / retreating driving unit 60 is provided between the guide units 37 at the left and right positions for advancing / retreating the support frame 34 in the horizontal direction.

As shown in FIGS. 10A and 10B, the advancing / retreating driving unit 60 of the second traversing device 30 includes a driving machine 61 that generates rotational power. As the drive machine 61, an electric motor can be used. The advancing / retreating drive unit 60 includes a horizontal movement mechanism 62 that moves the traverse drive unit 31 in the horizontal direction by the guide unit 37 by the rotational power of the drive machine 61. The horizontal movement mechanism 62 has an arm member 63 that is rotated downward by the drive machine 61.

As shown in FIG. 9, the arm members 63 are provided at left and right positions, and they are connected by a connecting shaft 64. The connecting shaft 64 is supported by a support plate 32a projecting downward from the beam member 32. The connecting shaft 64 is rotatable by a bearing provided on the support plate 32a. A chain 61b is hung between the sprocket 61a provided on the drive machine 61 and the sprocket 64a provided on the connecting shaft 64. Therefore, by rotating the drive machine 61, the connecting shaft 64 is rotated in a predetermined direction.

The arm member 63 is formed in a curved portion 63a that protrudes unilaterally from a portion fixed to the connecting shaft 64 and whose tip portions are curved in opposite directions. An advancing / retreating roller 65 is provided at the end of the curved portion 63a. The advancing / retreating roller 65 is provided so as to rotate at an axial center in the same direction as the axial center of the connecting shaft 64. By providing the curved portion 63a at the tip end portion of the arm member 63, the advancing / retreating roller 65 is arranged at a position separated from both ends of the connecting shaft 64 in the left-right direction. In the advancing / retreating roller 65, the axial center of the advancing / retreating roller 65 is arranged at a position close to the axial center of the connecting shaft 64, and the turning radius is small.

On the other hand, as shown in FIG. 10A, the guide plate 66 is projected from the support frame 34 in the direction of the advancing / retreating roller 65. The guide plate 66 is provided with a groove portion 67 extending in the vertical direction. The advance / retreat roller 65 is engaged with the groove portion 67. Therefore, in the advancing / retreating drive unit 60 of this embodiment, the advancing / retreating roller 65 is rotated by a predetermined radius by the arm member 63 by rotating the connecting shaft 64 by the driving machine 61. In this way, the horizontal movement mechanism 62 becomes a groove cam mechanism 68 in which the advancing / retreating roller 65 moves along the groove portion 67, and the guide plate 66 provided with the groove portion 67 moves in the horizontal direction integrally with the support frame 34. ing. In the groove cam mechanism 68, the advancing / retreating roller 65 is a cam member. The rotation angle of the arm member 63 can be set by the height of the contact member 32c provided on the drive machine base 32b.

Further, as shown in FIGS. 11A and 11B, in the second traversing device 30, the connecting shaft 64 connecting the arm member 63 is provided with a weight 69A as an urging means 69. The weight 69A is provided on the bracket 54b that projects in the direction opposite to the projecting direction of the arm member 63 with respect to the axis of the connecting shaft 64. As shown in FIG. 11B, with respect to the rotational moment M1 acted by the advancing / retreating roller 65 provided at the tip end portion of the arm member 63 projecting to one side with respect to the axial center of the connecting shaft 64 by the weight 69A. A rotational moment M2 in the opposite direction is applied to the axial center of the connecting shaft 64. The rotational moment M2 due to the weight 69A is larger than the rotational moment M1 due to the advancing / retreating roller 65. As a result, even if the advancing / retreating roller 65 is located either in the front or rear with respect to the connecting shaft 64, the advancing / retreating roller 65 is urged upward by the rotational moment M2 by the weight 69A and urged toward the end of the groove portion 67. The state is maintained (FIG. 10 (A)).

Therefore, in the case of the second traversing device 30, even if a failure occurs in the drive system (drive machine 61, chain 61b, etc.) that rotates the connecting shaft 64 by providing the weight 69A as the urging means, the advancing / retreating roller 65 Is maintained in a state of being urged toward the end of the groove 67 and does not hang downward. That is, the state is maintained when the traverse drive unit 31 is retracted, and the state is maintained when the traverse drive unit 31 is advanced.

FIG. 12 is a side view showing another urging means. FIG. 12 is a diagram in which an urging means is added to FIG. 10 (A). The urging means 69 of this example is a spring member 69B hung between the drive machine base 32b fixed to the beam member 32 and the shaft of the advancing / retreating roller 65. The upper end of the spring member 69B is supported by the drive machine base 32b at a position above the axis of the connecting shaft 64. According to the spring member 69B, when the advancing / retreating roller 65 is rotated forward or backward beyond the lower axis of the connecting shaft 64, the advancing / retreating roller 65 is urged toward the end of the groove portion 67 by the spring force of the spring member 69B. The state of being kept is maintained.

The urging means may be another configuration as long as it is a traversing device having a configuration in which the arm member 63 is rotated downward and the position of the advancing / retreating roller 65 is maintained even if a failure occurs in the drive system. May be good.

According to such a second traversing device 30, even when the traversing device is provided above the warehousing / delivery unit 6, the warehousing / delivery unit is provided by arranging the drive system upward and rotating the arm member 63 downward. The height T2 above 6 can be secured. That is, unlike the first traversing device 20, the drive system can be prevented from being positioned below the traversing drive unit 21 having the traversing roller 25. Therefore, it is possible to keep the height of the mechanical parking facility 1 low.

Moreover, the second traversing device 30 can be used with the vertical direction reversed depending on the location to be mounted as having the same structure as the first traversing device 20 described above. By doing so, the parts of the first traversing device 20 and the second traversing device 30 can be shared, and the cost of the traversing device can be reduced.

Further, by providing the advancing / retreating drive unit 60 with the urging means 69 as described above, a failure occurs in the drive system, for example, when the brake of the drive machine 61 fails or when the drive chain 61b breaks. Also, the arm member 63 can be prevented from rotating downward.

Then, even with this second traversing device 30, if the arm member 63 is rotated via the connecting shaft 64 by the drive machine 61 of the advance / retreat drive unit 60, the advance / retreat roller 65 provided on the arm member 63 becomes the support frame 34. It moves in an arc along the groove 67 provided in the guide plate 66 of the above. Then, by the movement of the advancing / retreating roller 65, the slide roller 37b provided on the bracket 37a of the guide portion 37 is moved in the horizontal direction along the guide surface 33a of the slide rail 33. As a result, the traverse drive unit 31 is moved in the horizontal direction integrally with the support frame 34. The amount of movement S in the horizontal direction is twice the turning radius of the advancing / retreating roller 65 provided on the arm member 63.

Therefore, the traverse drive unit 31 can be moved in the horizontal direction between the state of being advanced to the hoistway 9 and the state of being retracted from the hoistway 9 by the advance / retreat drive unit 60. Since the traversing drive unit 31 is moved forward and backward in the horizontal direction, the height of the second traversing device 30 can be suppressed. Therefore, even with the second traversing device 30, when the traversing drive unit 31 is retracted when the pallet 100 is moved up and down, the traversing drive unit 31 can be retracted if the pallet 100 is released slightly upward. This makes it possible to shorten the time for raising and lowering the pallet 100 and to move the pallet 100 quickly. Further, even when the pallet 100 is supported by the traverse drive unit 31, if the pallet 100 is slightly released upward from the traverse drive unit 31 with the traverse drive unit 31 retracted from the hoistway 9, the traverse drive unit 31 Can advance to the hoistway 9. Then, if the lifted pallet 100 is lowered and supported by the traverse drive unit 31, a series of operations can be performed quickly. In this way, the second traversing device 30 also makes it possible to quickly move the pallet 100 to the target position.

Further, by rotating the sprocket 71a in the opposite direction and rotating the connecting shaft 74 in the opposite direction by the drive machine 71, the link member 75A rotates in the opposite direction to the support frame 24 via the bracket 77. The provided traversing roller 25 can be advanced to the hoistway 9.

The traversing roller 25 provided on the frame 24 can be retracted from the hoistway 9. Further, by rotating the drive machine 81 in the opposite direction (for example, counterclockwise in the drawing), the traverse is provided on the support frame 24 integrally with the moving frame 84 via the other chain 83 (not shown). The roller 25 can be advanced to the hoistway 9. The horizontal movement mechanism 83 is provided at two locations near both ends in the width direction, the connecting shaft 54 is rotated by the drive machine 81 as shown in FIG. 4, and the moving frame 84 is moved by the connecting shaft 54 via the chain 83.

(Summary)
As described above, according to the first traversing device 20 and the second traversing device 30, in the mechanical parking facility 1 having a configuration in which the pallet 100 is moved up and down and traversed to store the automobile V, the traversing is advanced and retreated to the hoistway 9. The drive units 21 and 31 can be moved forward and backward in the horizontal direction. Therefore, it is possible to suppress the heights of the traversing devices 20 and 30 and keep the height of the mechanical parking facility 1 low. Moreover, since the distance for releasing the pallet 100 upward when the pallet 100 is placed on the traversing devices 20 and 30, the distance can be reduced, so that the pallet 100 can be efficiently moved. Therefore, it is possible to shorten the moving time of the pallet 100 in the mechanical parking facility 1.
