[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical circulation type multi-story parking device for storing a vehicle by circulating a plurality of cages on which a pallet for mounting a vehicle is mounted in a vertical direction. The present invention relates to an improvement of a mechanism for lifting a pallet placed on a circulated cage from the cage and turning the pallet.

[0002]

2. Description of the Related Art A vertical circulation type multi-story parking device of this type is known, for example, from Japanese Utility Model Laid-Open No. 1-62462. In this device, generally, a large number of cages are circulated vertically from a lower end position in a state of being suspended at predetermined pitch intervals by an endless chain, and a pallet for mounting on a vehicle can be lifted in each cage. It is placed in a state. Further, a pallet lifting mechanism for lifting a pallet on the cage circulated and moved from the cage to the lower end position and turning the pallet is installed at a lower end position of the cage which is a loading / unloading position of the vehicle. A lifting frame which is raised and lowered by the means, and a turning frame provided on the lifting frame and supporting the pallet mounted on the cage at the lower end position and turning in a horizontal plane by the turning means. Then, at the time of entry, after the vehicle is driven in a forward state on the pallet of the cage at the entry / exit position, the pallet is lifted to a predetermined height position by the lifting mechanism, and the direction of the vehicle is reversed by 180 ° in the horizontal plane, This allows the vehicle to move out of the entrance / exit position in the forward state when leaving the vehicle.

On the other hand, the above vertical circulation type multi-story parking device includes:
There is a need to increase the number of storage vehicles by increasing the number of cages, and in order to respond to this, in order to make the pitch of the suspension of the cage as small as possible,
It is intended to minimize the vertical dimension of each cage. In this case, when the pallet is lifted from the cage at the loading / unloading position, it is necessary to reliably prevent the pallet and the vehicle mounted on the pallet from interfering with the cage when turning. is there.

[0004]

By the way, in the conventional vertical circulation type multi-story parking device, the pallet can always be lifted to a predetermined height position at the loading / unloading position, but the cage can be lifted from the fixed position. May also be lower. This is the case, for example, when the number of stowed vehicles is large and the load causes the endless chain to stretch, in which case the pallet's relative lift with respect to the cage is increased more than necessary due to the lowered cage. As a result, the vehicle on the pallet may come into contact with the upper part of the cage or the like at the time of turning. Therefore, the vertical dimension of the cage must be set slightly larger in anticipation of the lowering of the cage, which hinders minimizing the vertical dimension of the cage.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to improve a pallet lifting mechanism of a vertical circulation type multi-story parking device, so that the height of a cage at a lower end position can be improved. Another object of the present invention is to make it possible to stabilize the relative lifting amount of the pallet with respect to the cage, and thereby to properly minimize the vertical dimension of the cage.

[0006]

In order to achieve the above object, according to the first aspect of the present invention, the lifting frame is always stopped at the same relative position with respect to the cage at the lower end position. The relative lift of the pallet with respect to the cage was made constant.

Specifically, according to the present invention, there are provided a plurality of cages on which a pallet for a vehicle is movably mounted upward and circulates vertically between a rising end position and a falling end position. A lifting frame provided below the cage at the lower end position and raised and lowered by lifting means; and a horizontal plane provided by the lifting frame and supported by the pallet mounted on the cage at the lower end position and turned by the turning means. A vertically circulating three-dimensional body comprising: a rotating frame that rotates inside; a lifting mechanism that lifts the pallet on the cage at the lower end position by raising the lifting frame with the rotating frame, and changes the direction of the pallet by rotating the rotating frame. The premise is a parking device.

A detecting means provided on the elevating frame for detecting that the position of the turning frame with respect to the cage has reached a predetermined position after the turning frame starts lifting the pallet when the elevating frame is raised; When the detecting means detects that the position of the frame with respect to the cage has reached a predetermined position, the control means controls the elevating means so as to stop the raising of the elevating frame.

According to a second aspect of the present invention, in the first aspect of the present invention, the detecting means is provided on the elevating frame so as to be vertically movable, and when the elevating frame is raised, the contact surface is at a predetermined position of the cage at the lower end position. A movable member which is brought into contact with the part from below and moves downward with respect to the elevating frame, and which comes into contact with the movable member when the movable member descends to a predetermined position with respect to the elevating frame when the elevating frame is raised. Switch means for detecting that the position of the revolving frame with respect to the cage has reached a predetermined position.

According to a third aspect of the present invention, in the first aspect of the present invention, the detecting means is provided when the cage at the lower end position moves down to a predetermined position relative to the lifting frame when the lifting frame is raised. It is constituted by switch means for contacting a predetermined portion of the cage from below to detect that the position of the revolving frame with respect to the cage has reached a predetermined position.

According to a fourth aspect of the present invention, in the first aspect of the present invention, the detecting means is provided at a plurality of positions on the periphery of the lifting frame. Then, the control means is configured to stop the raising of the lifting frame by controlling the lifting / lowering means when all the detection means detect that the position of the turning frame with respect to the cage has reached the predetermined position.

[0012]

According to the above construction, when the lifting frame is raised by the lifting means with respect to the cage circulated to the lower end position, the turning frame on the lifting frame is placed on the cage. After the swivel frame contacts the pallet from below during the ascent, the pallet is lifted from the cage in accordance with the rise of the lifting frame while being supported by the swivel frame from below. . When the position of the pallet with respect to the cage becomes a predetermined position after the pallet is started to be lifted by the revolving frame with the rise of the lifting frame, the detecting means provided on the lifting frame detects this. Further, the elevating means is controlled by the control means having received the signal from the detecting means, and the elevating frame is stopped from being lifted while the pallet is being lifted from the cage. At this time, the height difference between the pallet and the cage supported by the revolving frame is determined by the position of the revolving frame with respect to the cage, and the position is always constant. As a result, the amount of lifting of the pallet from the cage is substantially constant irrespective of the height difference of the cage itself.

According to the second aspect of the present invention, the lifting frame is raised by the lifting means together with the turning frame with respect to the cage at the lower end position, and the pallet is lifted from the cage by the turning frame in the middle of the lifting. Then, the contact surface of the movable member provided on the elevating frame comes into contact with a predetermined portion of the cage from below as the elevating frame rises. At this time, since the abutting surface can abut on the cage in a spread in a plane direction intersecting with the ascending direction, even if there is a displacement in the horizontal plane direction between the movable member and the cage, the range of the spread is As a result, the movable member after the contact moves downward relative to the lift frame in accordance with the rise of the lift frame. The switch means of the lifting frame contacts the movable member when the movable member moves down to a predetermined position with respect to the lifting frame,
This detects that the position of the turning frame with respect to the cage has reached a predetermined position. Further, the elevating means is controlled by the control means which receives the signal from the switch means, and the elevating frame is stopped from being lifted while the pallet is lifted from the cage. Therefore, even if the cage at the lower end position and the lifting frame are relatively displaced in the horizontal plane direction, the detection of the cage by the detecting means is reliably performed by the mechanical operation, and the predetermined lifting amount of the pallet from the cage is secured. Is done.

According to the third aspect of the invention, when the elevating frame is raised by the elevating means together with the revolving frame with respect to the cage at the lower end position, the cage moves downward relative to the elevating frame. The pallets on the cage are lifted by the pivot frame during the ascent. Then, the detecting means provided on the elevating frame detects that the position of the turning frame with respect to the cage has reached a predetermined position. Further, the elevating means is controlled by the control means having received the signal from the detecting means, and the elevating frame is stopped from being lifted while the pallet is being lifted from the cage. At this time, the detecting means comprises a switch means, and the switch means contacts the predetermined portion of the cage directly from below when the cage relatively moves down to a predetermined position with respect to the elevating frame, so that the turning frame is provided. Since it is detected that the position with respect to the cage has reached the predetermined position, the configuration of the detecting means is simplified as compared with the second aspect of the present invention.

According to the fourth aspect of the present invention, the lifting frame is raised by the lifting means together with the revolving frame with respect to the cage at the lower end position, and the pallet is lifted from the cage by the revolving frame being raised. Each of the detecting means provided on the peripheral portion of the elevating frame detects that the position of the turning frame with respect to the cage has reached a predetermined position as the elevating frame rises. Further, the elevating means is controlled by the control means which receives signals from all the detecting means, and the elevating frame is stopped from being lifted while the pallet is being lifted from the cage. At this time, when the raising and lowering frame is stopped when all of the detecting means have detected, the part of the cage corresponding to the detecting means that has been detected most recently among all the detecting means, that is, each detecting means A predetermined lifting amount of the pallet is secured for a part of the corresponding cage where the lifting amount of the pallet is the smallest as compared with the other parts. This allows
Even if the cage at the lower end position is twisted or tilted and the parts of the cage have variations in the vertical direction, a predetermined lifting amount of the pallet is secured for the entire cage.

On the other hand, each of the cages 1 has a cage lower member 1a composed of a rectangular frame, and both ends of each side portion of which both ends are located in front and rear of the longitudinal direction of the cage lower member 1a. And a pair of inverted U-shaped hanger members 1b, 1b which are connected to
1b is provided with a stay 1c connected between the upper ends in the longitudinal direction of the cage lower member 1a, and both ends of which are supported by the endless chain via an attachment (not shown). A pallet 3 is mounted on the cage lower member 1a so as to be liftable.
The central portion of a is configured such that the revolving frame 8 when ascending and descending can pass in the vertical direction.

At the four corners of the upper surface of the elevating frame 6, when the elevating frame 6 is raised, the position of the swivel frame 8 relative to the cage 1 in the loading / unloading position 2 after the swivel frame 8 starts lifting the pallet 3 is at a predetermined position. Detecting means 10 for detecting that the condition has been reached are provided. The detecting means 10 is provided on the elevating frame 6 so as to be movable up and down. When the elevating frame 6 is lifted, the contact surface 11a is brought into contact with a predetermined portion of the cage lower member 1a from below, and the detecting means 10 is moved relative to the elevating frame 6. And that when the movable member 11 descends to the predetermined position with respect to the elevating frame 6, the movable member 11 comes into contact with the movable member 11 and the position of the revolving frame 8 with respect to the cage 1 becomes the predetermined position. And a limit switch 12 as a switch means for detecting the

More specifically, the movable member 11 is vertically guided and supported by respective guide holes (not shown) penetrating in the vertical direction of the elevating frame 6.
b, and a contact plate 11c provided at the upper end of the shaft portion 11b and extending in the horizontal plane direction. The contact surface 11a is constituted by an upper surface of the contact plate 11c having the horizontal extension. The movable member 11 is constantly urged upward by a compression coil spring 13 interposed between the contact plate 11c and the elevating frame 6 around the shaft portion 11b. The shaft portion 11b is prevented from coming out of the guide hole upward by a retaining member (not shown) provided at the lower end. On the other hand, the limit switch 12 has a lever 12a that can swing downward from an upper position in the vertical plane. And the lifting frame 6
When the movable member 11 moves down to the predetermined position relative to the elevating frame 6 when the abutment surface 11a abuts on the cage lower member 1a from below after the revolving frame 8 starts lifting the pallet 3 The lever 12a of the limit switch 12 is moved to the contact plate 11c of the movable member 11.
The lower surface is pushed downward to detect that the position of the turning frame 8 with respect to the cage 1 has reached a predetermined position.

Basically, each part of the cage lower member 1a with which each of the movable members 11 abuts is located in the same horizontal plane. On the other hand, the tip of the lever 12a of each of the limit switches 12 is also located in the same horizontal plane. When the pallet 3 is lifted from the cage lower member 1a by a predetermined lifting amount H when the cage 1 at the loading / unloading position 2 is in a twisted state and an inclined state within an appropriate range, each movable member 11 Switch 12
Are set so as to simultaneously push the levers 12a.

As shown in FIG. 3, the detection signals of all the limit switches 12 are inputted to the control device 9, and the control device 9
When all the detection means 10 detect that the position with respect to the predetermined position, the actuator of the jack 5 is controlled to stop the lifting of the lifting frame 6.

Therefore, according to this embodiment, when one cage 1 on which an empty pallet 3 is placed is stopped at the loading / unloading position 2, the jack 5 is extended and the lifting frame 6 is moved relative to the cage 1 by the turning frame. 8, the pallet 3 is lifted from the cage lower member 1a by the rotating frame 8 in the middle of the lifting. Then, when the position of the turning frame 8 with respect to the cage 1 becomes a predetermined position after the lifting of the pallet 3 is started, the detecting means 10 of the elevating frame 6 detects this. At this time, the height difference between the lower surface of the pallet 3, that is, the upper surface of the revolving frame 8 and the cage lower member 1a is determined by the position of the revolving frame 8 with respect to the cage 1, and the position is always constant. That is, it is relatively lifted from the cage 1 by a certain amount H. In this embodiment, the lifting amount H is substantially equal to the height difference L between the upper surface of the revolving frame 8 and the tip of the lever 12a of the limit switch 12, and strictly speaking, the thickness of the contact plate 11c is determined by the height difference L. The value is obtained by subtracting the dimension T (H = LT). And in this state jack 5
Is stopped by the control device 9, and the lifting of the lifting frame 6 is stopped. By these things, the warehouse position 2
, The pallet 3 can be lifted with respect to the cage 1 by a predetermined lift amount H, which is a constant value, even if the cage 1 is displaced in the vertical direction from the fixed position due to elongation of the chain. Therefore, by minimizing the lifting amount H, the vertical dimension of the cage 1 can be minimized, so that the number of cages of the parking device can be increased and the number of stored vehicles can be increased.

When the detecting means 10 performs the detection,
The movable member 11 has a contact surface 11 having a spread in a horizontal plane direction.
a, the movable member 11 and the cage lower member 1a surely come into contact with the predetermined portion within the range of the spread even if there is a displacement in the horizontal plane direction between the movable member 11 and the cage lower member 1a. . In other words, even if the cage 1 at the loading / unloading position 2 and the lifting frame 6 are relatively displaced in the horizontal plane direction, the detecting operation of the detecting means 10 with respect to the cage lower member 1a is reliably performed, and the predetermined lifting amount H of the pallet 3 is obtained. Will be secured.

Further, all the detecting means 1 confirm that the position of the turning frame 8 with respect to the cage 1 has reached a predetermined position.
Since the lifting of the lifting frame 6 is stopped when 0 is detected, the portion of the cage lower member 1a corresponding to the detection unit 10 that has detected the latest among all the detection units 10, that is, each of the detection units 10 Corresponding cage lower member 1a
Among the parts, the predetermined lift amount H of the pallet 3 is ensured also for a part where the lift amount of the pallet 3 is the smallest compared to the other parts. For this reason, even if each part of the cage lower member 1a has a variation in height as compared with an appropriate state due to the twist or inclination of the cage 1, the pallet 3 is moved at least to a predetermined position with respect to all the parts of the cage lower member 1a. It can be lifted to a position where the lifting amount H can be secured.

In the first embodiment, the respective portions of the cage 1 where the movable members 11 contact each other are in the same horizontal plane, and the levers 12a of the limit switches 12
Although the tips are located in the same horizontal plane, the abutting portions may be located in different horizontal planes. However, in that case, each movable member 11
If the thickness dimensions of the contact plates 11c are the same, it is necessary to set the vertical position of the tip of the lever 12a of the limit switch 12 according to the vertical position of each contact portion.

In the first embodiment, the lifting frame 6
The detection means 10 is disposed at the four positions described above.
It is sufficient to dispose it only at the location.

(Embodiment 2) FIG. 4 and FIG.
And the same parts as those in the first embodiment are denoted by the same reference numerals. In the vertical circulation type multi-story parking device, in the pallet lifting mechanism A, detection means for detecting that the position of the turning frame 8 with respect to the cage 1 has reached a predetermined position is constituted by a limit switch 14 as a switch means. Reference numerals 14 are arranged at the four corners of the upper surface of the lifting frame 6 similarly to the first embodiment. And each limit switch 14
When the cage 1 at the loading / unloading position 2 moves down to a predetermined position relative to the lifting frame 6 when the lifting frame 6 is raised, the cage 1 directly comes into contact with a predetermined portion of the cage lower member 1a from below, and It is configured to detect that the position with respect to the cage 1 has reached a predetermined position. In other words, when the end of the lever 14a of the limit switch 14 is pushed downward by the cage lower member 1a when the lifting frame 6 is raised, the limit switch 14 outputs a detection signal.

Therefore, according to the second embodiment, when it is detected that each limit switch 14 has reached a predetermined position with respect to the cage lower member 1a, each limit switch 1
4 is pushed and operated by directly contacting the tip of the lever 14a with the cage lower member 1a.
Means that the position of the revolving frame 8 with respect to the cage 1 has reached a predetermined position, which is directly detected by mechanical operation. Then, in a state where the pallet 3 is lifted from the cage 1 by a predetermined lifting amount H, the jack 4 is controlled by the control device 9 and the lifting of the lifting frame 6 is stopped. As a result, the detection operation of the limit switch 14 with respect to the cage lower member 1a is reliably performed mechanically without using a separate member, and the predetermined lifting amount H of the pallet 3 from the cage 1 can be secured. The movable member of the first embodiment can be omitted, and the lifting amount can be made constant with a small number of parts.

In the second embodiment, the limit switch 14 is used as the switch means, and the detection is performed by the lever 14a of the limit switch 14 directly contacting the cage 1. When a non-contact sensor such as a proximity switch is used as the means, the position of the lifting frame relative to the cage is determined when the detection means approaches a predetermined distance from the corresponding part of the cage, that is, when the pallet is lifted from the cage by a predetermined lifting amount. May reach a predetermined position.

For the parking device lifted from the cage, the lifting frame is provided with detection means for detecting that the position of the revolving frame with respect to the cage has reached a predetermined position, and the lifting of the lifting frame is stopped when the detection means detects the rotation frame. By doing so,
The lifting frame can be stopped with the pallet lifted from the cage by a certain amount, and the lifting amount of the pallet with respect to the cage can be made substantially constant regardless of the height difference of the cage at the lower end position. As a result, it is possible to reduce the vertical height of the cage without interfering with the vehicle at the time of turning, by minimizing the lifting amount, thereby increasing the number of cages of the parking device and reducing the number of stored vehicles. Increase can be achieved.

According to the second aspect of the present invention, a vertically movable movable member having a contact surface capable of contacting a predetermined portion of the cage at the lower end position, and the movable member is moved to a predetermined position with respect to the lifting frame. The switch means for detecting that the position of the revolving frame with respect to the cage at the predetermined position with respect to the cage when the movable member relatively lowers is moved, thereby forming a detecting means, The movable member can be reliably brought into contact with a predetermined portion of the cage in the range of the spread in the direction, so that the position of the lifting frame with respect to the cage at the predetermined position can be reliably detected by mechanical operation. Therefore, even when there is a horizontal displacement between the cage and the elevating frame, it is possible to secure a constant lifting amount of the pallet with respect to the cage.

According to the third aspect of the present invention, when the cage at the lower end position is relatively moved down to the predetermined position with respect to the elevating frame when the elevating frame is raised, the detecting means contacts the cage from below. The moving member according to the second aspect of the present invention can be omitted by using the switch means for detecting that the position of the revolving frame with respect to the cage has reached a predetermined position, and the lifting amount of the pallet with respect to the cage can be reduced with a small number of parts. Can be stabilized.

According to the fourth aspect of the present invention, the detecting means is provided at a plurality of positions of the lifting frame, and all the detecting means detect that the predetermined position is reached for each part of the cage at the lower end position. When the lifting frame is stopped from rising, the lifting frame can be stopped when the lifting frame reaches a predetermined position with respect to the highest part of each part of the cage. Of the cage at the highest position in the cage can be secured. Therefore, even when the cage at the lower end position is twisted or tilted, the pallet can be raised to a position where at least a predetermined lifting amount required for turning can be secured for all of the parts of the cage.
