Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mechanical parking facility and a positioning mechanism of a vehicle turning device therefor. More specifically, a mechanical parking facility equipped with a vehicle turning device that turns a vehicle entering and leaving the mechanical parking device to change its front-rear direction, and positioning the vehicle turning device at a predetermined position. Related to the mechanism.
[0002]
[Prior art]
As a mechanical parking facility provided with the vehicle turning device, for example, one disclosed in Japanese Patent No. 2649739 is known. This mechanical parking facility is an elevator-type parking facility, in which parking shelves (hereinafter simply referred to as shelves) for accommodating pallets for vehicle mounting are arranged in multiple stages along both sides of the elevator hoistway. It is. Then, the elevator moves to the designated shelf and transfers (transfers) the pallet between the shelf and the elevator.
[0003]
A vehicle turning device (hereinafter, referred to as a turning device) that turns a pallet so that a vehicle can enter and leave the vehicle in the forward direction is installed on the entrance and exit floor of the parking facility. This turning device is provided in the elevator itself and moves up and down together with the elevator. However, as will be described below, the turning device and the elevator can be relatively displaced up and down relative to each other by a small dimension.
[0004]
When turning the pallet, the turning device rotates the pallet 180 ° with the pallet slightly lifted from the pallet mounting portion of the elevator, and lowers when the vehicle is positioned in a predetermined direction, and lowers the pallet on the pallet mounting portion of the elevator. Place and position. This positioning is performed by engaging a vertical engaging groove of a guide plate fixed to the pallet with a horizontal engaging pin fixed to the elevator as the pallet descends. This positioning prevents the pallet from being inadvertently displaced in the turning direction.
[0005]
However, in order to perform the above-described positioning, it is necessary to move the pallet up and down from the elevator by the turning device. Further, since the elevator is provided with a positioning mechanism that engages with the engaging pin of the pallet, the turning stop position of the pallet is limited. For example, as described above, positioning can be performed only at the 180 ° inversion position.
[0006]
The present invention has been made in order to solve such a problem, and when defining a pallet turning position, positioning is performed when the pallet stops turning without requiring lifting and lowering of the pallet. It is an object of the present invention to provide a turning device having an improved degree of freedom in selecting a position and a mechanical parking facility provided with the turning device.
[0007]
[Means for Solving the Problems]
The positioning mechanism of the turning device according to the present invention,
A turning device mounted on a mechanical parking facility for placing and turning a pallet for mounting on a vehicle, an engaging portion disposed on the pallet, and the engaging device installed on the mechanical parking facility A pallet holding device that engages with and disengages from the engaging portion with the horizontal movement of the portion to regulate the turning position of the pallet. A rotating body having a recess is provided.
[0008]
With this configuration, the engaging portion that moves horizontally with the rotation of the pallet contacts the rotating body and engages with the engaged recess. Therefore, there is no need to raise and lower the pallet to engage the engaging portion of the pallet with the engaged recess of the pallet holding device.
[0009]
In addition, it is preferable that the pallet holding device has a positioning mechanism having a stopping device for stopping and rotating the rotating body.
[0010]
Further, a plurality of engaged recesses of the rotating body are formed, and the stopping device engages and stops the rotating body by rotating into and out of the one engaged recess so as to freely rotate. A positioning mechanism having a projection is preferable. This is because the rotating body can be stopped and rotated by a simple operation.
[0011]
In addition, a positioning mechanism in which a roller is rotatably attached to the tip of the engaging projection is preferable. This is because the engagement convex portion smoothly enters and retracts into the engaged concave portion.
[0012]
Alternatively, a positioning mechanism is preferably configured such that the stopping device can stop the rotation by applying a braking force by friction to the rotating body. Because it is easy to obtain.
[0013]
Further, it is preferable that the pallet holding device be provided with a detent mechanism which is provided with a detent mechanism capable of elastically stopping the rotating body corresponding to the position of each engaged recess. This is because the posture in which the rotating body receives the engagement of the engaging portion of the pallet can be maintained. The term "elastically stop" means that the stop is released because the stop force is released by an external force greater than a predetermined value.
[0014]
The rotating body is formed in a substantially disk shape, the engaged recesses are formed at a plurality of positions at an equal angle with respect to the center of the rotating body, and the detent mechanism includes a rotating body. A plurality of recesses formed in the rotating body at the same angle as the engagement recess with respect to the center of the body, and an engagement body urged to engage with the recess. A positioning mechanism is preferred.
[0015]
Further, the rotating body is formed in a disk shape, and the engaged recess is formed by a notch extending in a radial direction from an outer peripheral edge of the rotating body, and the notch is formed with respect to a center of the rotating body. It is formed at a plurality of positions at an equal angle, and has a shape in which the degree of opening is increased outwardly for the entrance of the engaging projection at the opening of the notch at the outer peripheral edge of the rotating body. A positioning mechanism formed with a portion is preferable.
[0016]
This is because when the rotating body is in a position to accept the engagement of the engaging portion of the pallet, the engaging portion that has moved horizontally can easily enter the notch.
[0017]
In addition, a plurality of the pallet holding devices are installed on a fixed portion of a mechanical parking facility existing below the pallet mounted on the turning device, and the arrangement of each pallet holding device is determined by the rotation of the pallet. It is preferable to use a positioning mechanism that is positioned substantially on the rotation locus of the engaging portion.
[0018]
This is because the pallet can be stopped and positioned at a plurality of desired positions.
[0019]
Mechanical parking equipment of the present invention,
The vehicle includes a pallet for mounting a vehicle, a turning device for mounting and turning the pallet installed on the entrance / exit floor of the mechanical parking facility, and any one of the positioning mechanisms described above.
[0020]
With such a configuration, the operation described above can be achieved.
[0021]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a turning device according to an embodiment of the present invention and a mechanical parking facility including the turning device will be described with reference to the accompanying drawings.
[0022]
FIG. 1 is a front sectional view showing an elevator-type parking facility which is one embodiment of a parking facility having a turning device according to the present invention. FIG. 2 is a diagram taken along the line II-II of FIG.
[0023]
In the parking facility 1, an elevator 3 for raising and lowering a pallet 2 on which a vehicle M is mounted is hung by a wire 4. A driving device (a hoisting device) 5 for winding up and feeding out the wire 4 to raise and lower the elevator 3 and A counterweight 6 is provided. On both sides of the hoistway 7 of the elevator 3, a multi-stage parking shelf (hereinafter simply referred to as a shelf) 8 is provided. A rail 22 (see FIG. 2) on which the pallet 2 can traverse is provided on each shelf 8, and the pallet 2 is placed on the rail 22.
[0024]
The elevator 3 moves up and down between the shelves 8 on both sides, moves to the shelf 8 of the called pallet 2, receives the pallet 2, and transports it to the loading / unloading floor E. In this parking facility 1, the entrance / exit floor E is the lowest floor (the first floor). The elevator 3 is provided with a moving device (not shown) for receiving and returning the pallets 2 from the shelves 8.
[0025]
The elevator 3 is provided with a turning device 10 for turning the placed pallet 2 in a horizontal plane. As will be described later, the turning device 10 can be operated only when the elevator 3 lands on the entrance / exit floor E.
[0026]
3, 4, 5 and 6 show the elevator 3 and the turning device 10 mounted on the elevator 3. FIG. 3 is a perspective view showing the elevator 3, and FIG. 4 is a plan view thereof. FIG. 5 is a vertical sectional view showing the elevator 3 in a state where the elevator 3 has landed on the entrance / exit floor E, and FIG. 6 is a vertical sectional view showing the elevator 3 in a suspended state away from the entrance / exit floor E upward. The elevator 3 includes an elevating body 11, a frame base 12 and a turning frame 13 integrated via a bearing 14. Therefore, the revolving frame 13 is configured to be revolvable with respect to the frame base 12. The frame base 12 and the lifting / lowering main body 11 are not allowed to turn relative to each other. As will be described later, the lifting / lowering main body 11 and the integrated body of the frame base 12 and the revolving frame 13 are assembled so as to be relatively displaceable in the vertical direction by a slight dimension (see FIGS. 5 and 6). .
[0027]
A pallet placing portion 23 for placing the pallet 2 is formed on the turning frame 13. A traversing rail 24 for placing the pallet 2 and guiding the pallet 2 on the lifting / lowering main body 11 is provided. The traversing rail 24 extends in the width direction of the lifting / lowering main body 11, and corresponds to the rail 22 of the shelf 8 when the elevator 3 stops at a predetermined position corresponding to the shelf 8. The frame base 12 is supported by the elevating body 11 so as to be vertically movable. When the elevator 3 descends to the entrance / exit floor E, the frame base 12 lands on the floor F in the pit and does not descend any further, but the elevating body part 11 continues to descend slightly. Is slightly displaced upward by a certain dimension (FIG. 5). As a result, the pallet 2 is placed on the pallet placing portion 23 of the turning frame 13.
[0028]
When the lifting / lowering main body 11 is lifted, the lifting / lowering main body 11 is slightly displaced upward relative to the frame base 12 by a certain dimension, and the traversing wheel 25 of the pallet 2 is placed on the traversing rail 24 of the lifting / lowering main body 11. (Figure 6). At this time, a guide roller 26 for guiding the pallet 2 so that the traversing wheel 25 is properly placed on the traversing rail 24 is disposed on the elevating body 11 (FIGS. 3 and 4).
[0029]
FIG. 7 is a perspective view showing a front half (or a rear half) of the pallet 2. As shown in FIG. 7, a traverse wheel 25 is provided on the lower surface of the pallet 2 via brackets 25a fixed near four corners of the pallet 2, and the traverse wheel 25 is mounted on the traverse rail 24 and the rail of the shelf 8. Roll on 22. Further, the pallet placing portion 23 of the revolving frame 13 is shaped so that the lower surface of the pallet 2 directly rests thereon.
[0030]
The relative vertical movement between the frame base 12 and the elevating main body 11 can be easily understood by comparing FIG. 5 and FIG. It is the lifting main body 11 that is actually lifted during lifting and lowering, and as shown in FIG. 6, a contact portion 15 formed on the lifting and lowering main body 11 abuts on the frame base 12 to support it from below. The table 12 is lifted together with the turning frame 13. At this time, the lifting / lowering main body 11 moves upward relative to the frame base 12. As shown in FIG. 5, when the elevator 3 has landed on the floor of the entrance / exit floor E, the frame base 12 has landed. That is, the frame base 12 is supported by the floor surface, so to speak, and the elevating body 11 is moved downward by its own weight relatively to the frame base 12.
[0031]
A turning drive for turning the turning frame 13 with respect to the frame base 12 is attached to the elevating body 11. This turning drive includes a first motor 16a and a second motor 16b. By these motors 16a, 16b, the revolving frame 13 is revolved via first and second revolving arms 17a, 17b which can reciprocate. That is, as is apparent from FIGS. 4 and 5 together, when the elevator 3 lands, the engaging projection 18 formed at the tip of the first turning arm 17a and the engaging member formed on the turning frame. Since the joint portion 19 is engaged, the revolving frame 13 is revolved by revolving the revolving arms 17a and 17b. The engaged portion 19 has a shape that allows the engaging projection 18 to pass in the vertical direction, but does not allow relative movement in the rotational direction when engaged. In this way, the turning device 10 can be operated only when the elevator 3 lands on the entry / exit floor E. The frame base 12, the turning frame 13 and the turning drive constitute a turning device 10.
[0032]
As shown in FIG. 8, a positioning mechanism for positioning the pallet 2 when the pallet 2 is turned by the turning device 10 and stopped at a predetermined position indicated by a two-dot chain line is provided. This positioning mechanism directly and temporarily fixes the pallet 2, and includes a pallet holding device 30 installed on the floor surface, which is a fixing portion of the loading / unloading floor E, and the pallet holding device fixed on the lower surface of the pallet 2. And an engaging pin 31 (see also FIG. 7) which engages with the engaging pin 30. The engaging pin 31 is provided in a horizontal direction on a bracket 31a projecting downward from the lower surface of the pallet. The engagement pin 31 moves in the horizontal direction as the pallet 2 turns, and abuts and engages with the pallet holding device 30.
[0033]
FIG. 9 shows the arrangement of the positioning mechanism in plan view. First, a rectangular first pit P1 in a plan view is formed on the floor surface of the entrance / exit floor E for landing the elevator 3 thereon. Further, in order to define a space for the pallet 2 to turn, a circular shallow second pit P2 centering on the center of the first pit P1 in plan view is formed. In the present embodiment, the engaging pins 31 are fixed at diagonal positions on the lower surface of the pallet 2 respectively, and the pallet is held at a predetermined position on the turning locus of the engaging pins 31 on the floor surface of the second pit P2. The device 30 is arranged. This means that the stop position of the pallet 2 is each position where the pallet 2 is turned by 180 °, and positioning is performed at this stop position. Of course, the installation position of the pallet holding device 30 is not limited to the above. It is easy to set the arrangement so that it can be stopped and positioned at a desired angular position.
[0034]
FIG. 10 shows the pallet holding device 30. FIG. 10A is a front view of the pallet holding device 30, and FIG. 10B is a side view thereof. The pallet holding device 30 is constituted by a mechanism called a so-called Geneva mechanism, and has a disk-shaped Geneva segment (hereinafter referred to as a rotating plate) in which a plurality of notches 32 as recesses to be engaged with the engaging pins 31 are formed. 33), a support base 34 for rotatably supporting the rotary plate 33, a stopping device 35 for stopping the rotation of the rotary plate 33, and an elasticity corresponding to the position of each notch 32 for the rotary plate 33. And a detent mechanism 36 that can be stopped temporarily. Reference numeral 34a is a bearing member that rotatably supports the rotating shaft 33a of the rotating plate 33. As shown in the figure, the surface of the rotating plate 33 extends substantially vertically. Therefore, the above-described engagement pin 31 extends substantially in the horizontal direction.
[0035]
In the present embodiment, the notches 32 are formed at four positions so as to extend in the radial direction from the outer peripheral edge of the rotating plate 33 at equal intervals of 90 °. Of course, the number is not limited to four, but may be five or more, two or three. As shown, the open end of each notch 32 extends outwardly so that both sides of the notch are approximately 90 ° from each other so as to guide the engaging pin 31 to be engaged. . In other words, it constitutes the guide portion 32a.
[0036]
As shown in the figure, the height position of the rotating plate 33 is a height at which the engaging pin 31 of the pallet 2 is located slightly above the rotation center of the rotating plate 33 when the elevator 3 has landed on the pit. Further, as shown in FIG. 10A, when the notch 32 is at a position of 45 ° with respect to the vertical direction and the horizontal direction (position for receiving the engaging pin), the rotating plate 33 is horizontally moved. The mating pin 31 is located at a height where it can enter the notch along the lower side of the guide portion 32a of the notch 32. As a result, the engaging pin 31 pushes and rotates the rotating plate 33, and the engaging pin 31 can be engaged with the vicinity of the deep end of the notch 32 when the engaging pin 31 reaches just above the rotation center of the rotating plate 33.
[0037]
The detent mechanism 36 includes four concave portions 37 formed at equal intervals of 90 ° on the outer periphery of the rotating plate 33, and a resilient engaging device 38 provided on the floor of the second pit P2. It is composed of In the present embodiment, each recess 37 is formed at a position 45 ° away from the center of each notch 32 on the outer circumferential circle of the rotating plate 33. In short, the recesses 37 may be formed at positions corresponding to the respective notches 32. If the number of the notches is 5 or more, 2 or 3, the number of the recesses 37 is 5 or more, 2 or 3 It is formed. The elastic engagement device 38 includes an engagement body 38a formed of a ball or the like engaged with the recess 37, an urging member 38b such as a coil spring for urging the engagement body 38a toward the recess 37, and And a housing 38c for accommodating the union 38a and the urging member 38b.
[0038]
As shown in the figure, the detent mechanism 36 elastically stops the rotary plate 33 so that the direction of the notch 32 is in the above-described receiving posture. Thereby, the engagement pin 31 can easily engage with the notch 32. When the rotating plate 33 rotates, the engagement body 38 a rolls on the outer peripheral edge of the rotating plate 33. Even when the engagement body 38a reaches the notch 32, the engagement body 38a is held by the housing 38c, and therefore does not spill out. In addition, since the guide portion 32 a is formed in the notch 32, the engaging body 38 a can easily escape from the notch 32.
[0039]
The position where the concave portion 37 is formed is not particularly limited to the outer periphery of the rotating plate 33. For example, a predetermined number may be formed on a circle centered on the rotation center on the side surface of the rotating plate 33. In this case, it is necessary that the engagement body of the engagement device be urged laterally toward the concave portion.
[0040]
The stopping device 35 is also provided on the floor of the second pit P2, and is constituted by a driving cylinder 39 having a rod 39a as an engaging projection that enters and retracts into the notch 32. As the drive cylinder 39, a hydraulic cylinder, an air cylinder, or the like can be employed, but a solenoid actuator, a motor, or the like can also be employed. The rod 39a is provided with a roller 39b at the tip thereof in order to facilitate the approach and retreat to the notch 32. When the pallet 2 stops at a predetermined position and the engagement pin 31 engages with the notch 32, that is, when the rotary plate 33 stops at a position where each notch 32 faces in the vertical direction and the horizontal direction, The rod 39a enters one notch 32 facing the direction. As a result, the stop of the rotating plate 33 is ensured, and the pallet is positioned.
[0041]
The pallet positioning operation performed by the positioning mechanism when the vehicle M enters the warehouse will be described with reference to FIGS. 11 and 12. FIG. 11 is a plan view showing the entry operation of the vehicle M, and FIG. 12 is a front view showing the movement of the positioning mechanism corresponding to the turning of the pallet when the vehicle is entered.
[0042]
Before the vehicle M enters the warehouse, the pallet 2 is in a state of being lifted and lowered by the elevator 3, and faces in that direction (FIG. 11A). Then, when an operation for storing is performed, the pallet 2 turns counterclockwise to face a direction corresponding to the storing (FIG. 11B). Accordingly, the engaging pin 31 of the pallet 2 approaches the pallet holding device 30 (FIG. 12A). The rotating plate 33 of the pallet holding device 30 is in a receiving position in which the notch 32 is oriented at 45 ° to the vertical direction, and is elastically stopped in this position by the detent mechanism 36.
[0043]
The pallet 2 stops turning when the pallet 2 reaches a direction corresponding to the entry direction of the vehicle M. This is a position turned by 90 ° from the initial state (FIG. 11C). In this state, the engagement pin 31 rotates the rotating plate 33 to orient the notch 32 in the vertical direction, and enters toward and engages with the notch 32 at the far end (FIG. 12B). Next, the rod 39a of the stopping device 35 enters the notch 32 oriented in the horizontal direction to fix the rotating plate 33 (FIG. 12B). In this state, the positioning of the pallet 2 is completed, and the vehicle M gets on the pallet 2 (FIG. 11C).
[0044]
It is detected that the vehicle M has entered the pallet, and the rod 39a is retracted from the notch 32 by the detection signal or the operation of the operator. Next, the pallet 2 on which the vehicle M is mounted starts to turn counterclockwise in the direction for moving up and down (FIG. 11D). Accordingly, the engagement pin 31 releases the engagement with the notch 32 by rotating the rotary plate 33 (FIG. 12C). The engagement is smoothly released by the presence of the notched guide portion 32a. On the other hand, the rotating plate 33 is in the receiving posture and is elastically stopped by the detent mechanism 36 (FIG. 12C). Then, the pallet 2 on which the vehicle M is mounted is turned by 90 ° and stopped at a position facing the direction in which the pallet should be moved up and down.
[0045]
As described above, the positioning of the pallet rotation stop position is performed by directly holding the pallet by the pallet holding device fixed to the pit floor, which is a fixed portion of the entrance / exit floor. Therefore, for example, when the vehicle rides on the pallet side, when the wheel gets on or hits a rising portion (reference numeral 2a in FIGS. 5 to 7), a lateral impact force is applied to the pallet. Does not affect the turning drive device, and the pallet is not accidentally moved.
[0046]
FIG. 13 shows another pallet holding device 40. The pallet holding device 40 uses a brake 41 instead of the drive cylinder 39 as a device for stopping the rotating plate 33. That is, the rotating shaft 33a of the rotating plate 33 extends rearward from the bearing 34a of the support base 34, and the brake 41 is disposed so as to grip the extended portion of the rotating shaft 33a. As the brake 41, various kinds of brakes such as an electromagnetic clutch, a disc brake, a drum brake and the like that apply a frictional force to the rotating shaft 33a to apply a brake can be applied. Of course, the brake 41 and the above-described stopping device 35 may be used in combination.
[0047]
In the positioning mechanism described above, the engaging pin 31 of the pallet extends horizontally, and the rotating plate 33 extends along the vertical direction. However, the present invention is not limited to this configuration. For example, the engaging pin may be provided to project downward from the lower surface of the pallet, and the rotating plate may be installed so that the surface thereof is horizontal. In addition, both may be inclined in a direction between the vertical direction and the horizontal direction. In short, what is necessary is just to install so that an engagement pin and a rotating plate may become substantially perpendicular.
[0048]
In the parking facility described above, the pallet holding device 30 is installed at one place, and the pallet is provided with two engaging pins, so that the pallet can be positioned at each of the positions where the pallet is turned by 180 °. However, the present invention is not limited to this configuration. For example, the pallet holding device may be installed at a plurality of desired positions on the turning locus of the engaging pin.
[0049]
In the positioning mechanism described above, the engaging pin is attached to the pallet, and the rotating plate, the detent mechanism, and the stopping device are installed on the floor of the pit. However, the present invention is not limited to such a configuration. For example, it is possible to install the rotating plate and the detent mechanism on the lower surface of the pallet, and to install the engaging pin and the stopping device on the pit floor.
[0050]
Next, the aforementioned moving device for the elevator 3 to receive and return the pallets 2 from the shelves 8 will be described. The swing arms 17a and 17b perform the function of the moving device. That is, after the engagement roller 20 provided at the tip of the second swing arm 17b engages with the engagement groove 21 (see FIGS. 6 and 7) provided on the lower surface of the pallet 2, the swing arm 17a , 17b are swiveled to traverse the pallet. As shown in FIGS. 7 and 8, the engagement groove 21 is shaped so as to allow the engagement roller 20 to pass in the longitudinal direction of the pallet and not allow the relative movement in the pallet width direction (the traverse direction of the pallet).
[0051]
The pallet returning operation and the receiving operation (traversing operation) will be briefly described with reference to FIG. As shown in FIG. 14A, the first turning arm 17a is turned in a predetermined direction by the two motors 16a and 16b so that the angle between the two turning arms 17a and 17b does not change, and the engagement roller 20 is engaged. The groove 21 is engaged. Next, as shown in FIG. 14B, the engagement rollers 20 are appropriately driven by the two motors 16a and 16b so as to move in the pallet width direction. Thus, the pallet 2 is traversed toward the shelf 8. As shown in FIG. 14C, when the pallet 2 is settled on the shelf 8, the second turning arm 17b is turned so that the first turning arm 17a does not rotate, and the engaging roller 20 is disengaged from the engaging groove 21. (Indicated by the two-dot chain line). When receiving a pallet from the shelf 8, the two turning arms 17a and 17b are operated in the reverse procedure. The driving of the swing arms 17a and 17b is described in detail in Japanese Patent Application No. 2001-239116 filed by the present applicant.
[0052]
The positioning mechanism of the vehicle turning device according to the present invention is not limited to the above-described embodiment, and may be applied to a vehicle turning device having another structure.
[0053]
【The invention's effect】
According to the present invention, when the turning position of the pallet is defined, the positioning is performed when the turning is stopped without requiring the pallet to go up and down, and the freedom of selecting the turning stop position accompanying the positioning is improved.
