[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an elevator type multi-story parking apparatus, and more particularly, to a vehicle direction change countermeasure on an entry floor.
[0002]
[Prior art]
In general, an elevator type multi-story parking apparatus is equipped with a turning device for moving a vehicle in front and advancing in consideration of the convenience of the user, and the usage of this turning device varies depending on the purpose. For example, various types of elevator type multi-story parking devices as described below have been developed.
[0003]
(1) Elevator elevator mounted with a turning device with a lift device (see Japanese Patent Laid-Open Nos. 4-281969 and 9-60327),
(2) A turning device having only a turning function without a lift device installed in a pit which is the lowermost end of the elevator hoistway (see Japanese Patent Application Laid-Open Nos. 7-150800 and 7-102814), and its turning device A lift device on both sides (see Japanese Patent No. 26799749),
(3) Elevator platform is equipped with a swing device that does not have a lift device and has only a swing function so that it can move up and down, and a claw that supports the swivel device from below is placed at the location corresponding to the entrance / exit of the swing device or elevator shaft Provided (see Japanese Utility Model Publication No. 7-25157 and Japanese Patent Application Laid-Open No. 7-48946),
Etc.
[0004]
[Problems to be solved by the invention]
However, in the elevator type multilevel parking apparatus of the type (1), the turning device has not only a turning function but also a lifting function. Therefore, this turning device with a lifting device is more than a turning device having only a turning function. The structure is complicated and the weight is increased. As a result, the maintainability of the elevator platform becomes worse, the wire rope that suspends the elevator platform is extended excessively, and a large capacity hoisting drive motor is used. Problems such as having to do this also occur.
[0005]
In the elevator type multilevel parking apparatus of the type (2), as shown in FIG. 4 (b), when the vehicle is turning, in order to support the pallet a from below with the turning device b, the turning device b is an elevator lift. The center opening d of c must pass up and down, and therefore there is a restriction that the size of the turning device b must be smaller than the size of the center opening d of the elevator platform c, The pallet support area of the apparatus b is reduced. Accordingly, the pallet a can be supported only at the center portion of the lower surface when the vehicle is turning, the support state of the pallet a (vehicle e) becomes unstable, and both ends in the width direction of the pallet a are easily bent. Some means for increasing the rigidity of the pallet a is required, such as attaching a reinforcing frame to the back surface. Therefore, in the above-mentioned JP-A-7-102814, a reinforcing member f having a large support area is placed around the central opening d of the elevator platform c, and the pallet a is supported from below by the turning device b when the vehicle turns. At this time, as indicated by phantom lines, the reinforcing member f is interposed therebetween to stably support the pallet a and increase the rigidity of the pallet a, but the reinforcing member f is not essential for the direction change. There is no denying that there is another. In the elevator type multilevel parking device of the type mentioned in (2) above, the turning device has only a turning function and no lifting function, but the same applies to a turning device with a lift device having both functions. I can say that.
[0006]
In the elevator type multi-story parking apparatus of the type (3), both publications require an operating mechanism for retracting and retracting the pawl, so that the structure is complicated and the entire weight of the turning device is applied to the pawl. You should also pay attention to the strength of your nails. In particular, in both of these publications, since the turning device is mounted on the elevator platform so as to be movable up and down, the turning device moves in the horizontal direction due to the inertial force generated at the start of the turn and at the end of the turn. In order to avoid this, it is necessary to extremely control the starting / stopping speed of the swivel device, and this lowers the loading / unloading efficiency.
[0007]
The present invention has been made in view of the above points, and its main purpose is to make the structure of the elevator platform complicated and increase its weight, to ensure the excessive rigidity of the pallet, The purpose is to eliminate the interposition of reinforcing members in between and the decrease in storage / exit efficiency.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is characterized in that, in the elevator type multilevel parking apparatus of the type (2), the turning device is mounted on the elevator lift so as to be movable up and down, and is not displaced. And
[0009]
Specifically, the present invention turns the vehicle together with the pallet in a horizontal plane by a turning device to change the direction of the vehicle and raises and lowers the elevator hoist along the elevator hoistway extending in the vertical direction. The following solution was taken for an elevator type multi-story parking system that delivers vehicles with pallets between a plurality of storage shelves provided in a layered manner on the side and the elevator platform. .
[0010]
That is, the invention described in claim 1 A central opening is formed in the center of the elevator platform. On the other hand, the swivel device includes a swivel base having a pallet support area formed larger than the size of the central opening of the elevator lift so that the entire width direction of the pallet can be supported. And The swivel device Cover the central opening with a swivel Elevator lift above It can be moved up and down. Further, the elevator hoistway corresponding to the entrance / exit port is a pit at the lower end of the elevator hoistway, and a turning device support means is provided in the pit, and when turning the vehicle, the turning device is moved from below the central opening of the elevator hoisting platform. It is supported by a turning device support means and is moved up relatively with respect to the elevator platform so that the pallet is kept in a separated state so as not to interfere with the elevator platform. Further, the movement in the horizontal direction is restricted by the restricting means while the turning device is supported by the turning device supporting means.
[0011]
With the configuration described above, in the invention described in claim 1, since the swivel device moves up relative to the elevator lift in relation to the swing support means, it is necessary to mount the lift device on the elevator lift. The structure of the elevator platform is simplified and the weight is reduced accordingly. In addition, this makes maintenance of the elevator platform easy, and the wire rope that suspends the elevator platform does not extend excessively, and it is also necessary to employ a large capacity hoisting drive motor. Absent.
[0012]
Also, when turning the vehicle, it is only the turning device support means that passes through the central opening of the elevator platform, and the turning device does not pass, Also Of swivel Pallet support area of swivel Than the size of the central opening of the elevator platform Too large Kiki Because The wide pallet support area of the swiveling device enables stable support of the pallet, and the swiveling device has a reinforcing function and does not require a reinforcing member.
[0013]
Further, since the swivel device is restricted from moving in the horizontal direction by the restricting means, even if the inertial force at the start of the turn and at the end of the turn acts on the swivel device, it moves in the horizontal direction and is displaced or dropped. Therefore, it is not necessary to control the starting / stopping speed of the turning device at extremely low speed, and the loading / unloading is performed efficiently. In addition, since the central part of the swivel device is stably supported from below by the swivel support means, there is no need for a nail as in the case where the periphery of the swivel device is supported by the nail. No mechanism is required, and the swivel support means has a simple structure.
[0014]
According to a second aspect of the present invention, in the first aspect of the present invention, a lift device is employed as the turning device support means, and the turning device is stopped at the entry level by the lifting operation of the lift device when the vehicle turns. The lift is lifted by the lift device from the elevator lift.
[0015]
With the above configuration, in the invention according to claim 2, the vehicle can be turned with the elevator platform being stopped at the entry level, and in this state, the vehicle can be put into and out of the pallet. Therefore, the loading / unloading operation is performed smoothly.
[0016]
According to a third aspect of the present invention, in the first aspect of the present invention, a fixed support base is adopted as the swivel support means, and the swivel device is received by the fixed support base from the elevator lift by the lowering operation of the elevator lift. It is characterized by doing so.
[0017]
With the above configuration, in the invention described in claim 3, since the turning device is delivered to the fixed support base by the lowering operation of the elevator lift, there is no lift device on the fixed support base side, and the structure is simplified. .
[0018]
According to a fourth aspect of the present invention, in the first aspect of the present invention, the restricting means includes an engaging pin provided on one of the turning device and the turning device supporting means, and an engagement provided on the other. The engaging pin is engaged with and disengaged from the engaging hole by a relative vertical movement of the turning device with respect to the turning device support means.
[0019]
With the above configuration, the claim 4 In the invention described in the above, the configuration of the restricting means is embodied. In this restricting means, since the engagement / disengagement between the engagement pin and the engagement hole is performed in conjunction with the operation of the elevator lifting platform and the turning device support means at the time of turning of the vehicle, there is no dedicated operation means, and the structure Becomes simple.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0021]
(Embodiment 1)
FIG. 2 schematically shows the overall configuration of the elevator type multilevel parking apparatus according to Embodiment 1 of the present invention. In this first embodiment, the elevator type multilevel parking apparatus is a lower entry type.
[0022]

An elevator hoistway 6 extending in the vertical direction is provided below the machine room 5 inside the building 1 so as to reach the entrance floor 3. An elevator hoistway 7 is disposed in the elevator hoistway 6. A large number of storage shelves 9 composed of two shelf rails 8 are provided on both sides.
[0023]
In the machine room 5, a plurality of pulleys 10 and a hoisting drive motor 11 driven and connected to one of them are respectively attached to a beam 12, and each pulley 10 has four pulleys. The middle part of the wire rope 13 is stretched over. One end of each of these wire ropes 13 is connected to the four corners of the elevator lift 7 so as to suspend and support the elevator lift 7 horizontally, and the other end of each wire rope 13 is connected to a counterweight 14. Then, each pulley 10 is rotated by starting up the hoisting drive motor 11, and each of the wire ropes 13 is wound or unwound to raise and lower the elevator lift 7 along the elevator hoistway 6. The vehicle C is delivered with the pallet P between the elevator lift 7 and each storage shelf 9.
[0024]
As shown in FIGS. 1 (a) to 1 (c), a pit 15 is provided in a recessed portion of the elevator hoistway 6 corresponding to the entry / exit port 2 as a turning device support means. The lift device 16 is installed. The lift device 16 includes a pair of X links 18 that expand and contract in the vertical direction by operation of a fluid pressure cylinder (not shown) on a base 17, and a support base 19 is attached to these X links 18.
[0025]
On the other hand, a central opening 20 through which the support base 19 of the lift device 16 can pass is formed at the center of the elevator lift 7 so as to correspond to the upper side of the lift device 16. It is mounted so as to be movable up and down so as to correspond to the portion 20. As shown in FIG. 4A, the swivel device 21 includes a swivel base 22 that extends over the entire width direction of the pallet P. The swivel base 22 has a pallet support area larger than the size of the central opening 20 of the elevator lift 7 so as to support the entire width direction of the pallet P, and is mounted on the elevator lift 7. Covers the central opening 20. Also, Although the detailed structure is omitted at the center of the rear surface of the swivel base 22, a known swirl comprising a gear meshing system disclosed in, for example, Japanese Patent Laid-Open No. 7-48946 cited in (3) as the above-described conventional example. A drive unit 23 is installed, and the turning table 22 is turned by driving the turning drive unit 23, and the vehicle C is turned 180 ° in the horizontal plane together with the pallet P so as to change the direction to the exit position of the previous advancement warehouse. It has become. In other words, the vehicle C enters the pallet P waiting on the entry floor 3 by the forward driving and enters the pallet P while moving out from the pallet P by the forward driving.
[0026]
When the vehicle turns, it is necessary not to disturb the turning operation of the vehicle C. For this reason, as shown in FIG. 1B, the lift device 16 prevents the pallet P from interfering with the elevator lift 7. The X-link 18 is extended and the center of the turning device 21 (the turning drive unit 23) is stopped by the floor 3a which is the entrance level of the entrance floor by the ascending operation of the support base 19. The support base 19 is supported from below the central opening 20 and is moved upward with respect to the elevator lift 7. That is, the support base 19 of the lift device 16 is passed through the central opening 20 of the elevator lift 7, and In 19, the swivel device 21 is lifted from the elevator lift 7 and the pallet P and the elevator lift 7 are kept separated.
[0027]
A plurality of engagement pins 24 project downward from the lower end of the turning drive unit 23 of the turning device 21, while a plurality of engaging holes 25 are formed at the upper end of the support base 19 of the lift device 16. It is formed corresponding to the combined pin 24. Then, as shown in FIG. 1B, in a state where the X link 18 of the lift device 16 is extended and the swivel device 21 is lifted and supported by the support base 19, the engagement pins 24 are moved to the engagement holes. 25, the horizontal movement of the swivel device 21 is restricted, and the X link 18 of the lift device 16 is contracted to support the swivel device 21 on the elevator lift 7 so that each of the above engagements is achieved. The pins 24 are detached from the respective engagement holes 25 to allow the swiveling device 21 to move in the horizontal direction. Therefore, the engaging pin 24 and the engaging hole 25 constitute a restricting means for restricting the movement of the turning device 21 in the horizontal direction. Contrary to the above, this restricting means forms a plurality of engagement holes 25 at the lower end of the turning drive unit 23 of the turning device 21, while raising the plurality of engaging pins 24 at the upper end of the support base 19 of the lift device 16. You may comprise by projecting to. Further, the regulating means may utilize surface contact due to the engagement of the concavo-convex shape between the lower surface of the turning drive unit 23 and the upper surface of the support base 19.
[0028]
In FIGS. 1A to 1C, reference numeral 26 denotes a transfer device such as a slide fork type or a chain conveyor method provided on the elevator lift 7. The transfer device 26 allows the elevator lift 7 to be connected to the elevator lift 7. The vehicle C is transferred together with each pallet P between the storage shelves 9. Reference numeral 27 denotes a movable deck provided on the entrance / exit 2 side at the upper end of the pit 15, and this movable deck 27 rotates upward when the vehicle C enters or exits the entry floor 3 and moves horizontally. While connecting the floor 3a of the entrance floor 3 and the pallet P on the elevator platform 7 in a posture, when the elevator platform 7 is raised and lowered or the turning device 21 is turned, it is rotated downward and is in a suspended posture. Interference with these is avoided.
[0029]
Next, a description will be given of how to change the direction of the incoming vehicle C by 180 ° in preparation for outgoing.
[0030]
First, an empty pallet P is transferred from the storage shelf 9 to be stored to the elevator lift 7, and the elevator lift 7 is lowered to the floor 3 a of the entry floor 3 as shown in FIG. At this time, the lift device 16 is in a lowered state, and the turning device 21 and the lift device 16 are separated from each other.
[0031]
Next, the movable deck 27 is rotated upward and held in a horizontal position, and after the floor 3a of the entry floor 3 and the pallet P on the elevator lift 7 are connected, the warehousing vehicle C is moved onto the pallet P by forward operation. Get in.
[0032]
Thereafter, as shown in FIG. 1 (b), the movable deck 27 is rotated downward so as not to interfere with the pallet P when the vehicle turns, and is held in a suspended position. 19 is passed through the central opening 20 of the elevator lift 7 and brought into contact with the turning drive unit 23 of the turning device 21 from below, and each engagement pin 24 is engaged with each engagement hole 25 from above, The swivel device 21 is lifted upward by the lift device 16. As a result, the incoming vehicle C is lifted from the elevator lift 7 together with the pallet P.
[0033]
After that, the turning drive unit 23 of the turning device 21 is driven to prepare for delivery so that the incoming vehicle C can be turned 180 ° in the horizontal plane and exited by forward driving.
[0034]
Thereafter, as shown in FIG. 1C, when the lift device 16 is lowered, the support base 19 of the lift device 16 moves downward from the central opening 20 of the elevator lift 7, and by this operation, the turning device 21 is moved. Is delivered to and supported by the elevator platform 7 and does not descend thereafter. Thereby, each engagement pin 24 is disengaged from each engagement hole 25, and the support 19 of the lift device 16 is separated from the turning drive unit 23 of the turning device 21. From this state, the elevator lift 7 rises to the target storage shelf 9 and transfers the warehousing vehicle C to the storage shelf 9 together with the pallet P.
[0035]
In the case of delivery, the elevator lift 7 on which the delivery vehicle C is mounted together with the pallet P is lowered to the floor 3a of the entry floor 3, and the movable deck 27 is rotated upward to move the floor 3a of the entry floor 3 and the elevator. After communicating with the pallet P on the elevator 7, the unloading vehicle C may be withdrawn from the loading / unloading port 2 by forward driving.
[0036]
As described above, in the first embodiment, since the lift device 16 is installed in the pit 15 and only the turning device 21 is mounted on the elevator lift 7, both are mounted on the elevator lift 7. In comparison with the lift device 16, the structure of the elevator lift 7 can be simplified and the weight can be reduced. In addition, this makes it possible to improve the maintainability of the elevator platform 7 and to eliminate the excessive elongation of the wire rope 13 that suspends the elevator platform 7, and the hoisting drive motor 11. As a result, it is possible to eliminate the need for a large capacity.
[0037]
In the first embodiment, when the vehicle turns, only the support base 19 of the lift device 16 passes through the central opening 20 of the elevator lift 7 and the turning device 21 passes through the central opening 20. Without , Also The size of the swivel base 22 of the swivel device 21 (Pallet support area) Is set to a size that can support the entire width direction of the pallet P without being restricted by the size of the central opening 20 of the elevator lift 7. Because Further, the pallet P can be stably supported by the wide pallet support area of the swivel base 22, and since the swivel base 22 also serves as a reinforcement, it is possible to eliminate the provision of a separate reinforcing member (FIG. 4). (See (a)).
[0038]
Further, in the first embodiment, since the horizontal movement of the swivel device 21 is restricted by the engagement between the engagement pin 24 and the engagement hole 25 that are restricting means, Even if the inertial force at the end of turning acts, the turning device 21 can be integrated with the lift device 16 so as not to be displaced or dropped in the horizontal direction. It is possible to eliminate the need for extremely low speed control and efficiently enter and exit. Moreover, since the center part (swivel drive part 23) of the turning apparatus 21 is stably supported from below by the support base 19 of the lift apparatus 16, it is not necessary to provide a nail as in the case where the periphery of the turning apparatus 21 is supported by the nail. Therefore, the structure of the lift device 16 side can be simplified without worrying about the strength of the nails and the mechanism for operating the nails. Furthermore, the engagement pin 24 and the engagement hole 25 are engaged / disengaged simultaneously with the operation of lifting the swivel device 21 from the elevator lift 7 or depositing it in the elevator lift 7 by the lift operation of the lift device 16. Therefore, there is no need for a dedicated operating mechanism, and a simple structure can be achieved.
[0039]
In addition, in the first embodiment, when the vehicle turns, the turning device 21 is lifted from the elevator lift 7 that is lowered to the floor 3a of the entry floor 3 and stopped by the lifting operation of the lift device 16. The vehicle C can be turned in a state where the elevator lift 7 is stopped on the floor 3a. Moreover, since the vehicle C can be put into and taken out from the pallet P in this state, the loading / unloading operation is performed. It can be done smoothly.
[0040]
(Embodiment 2)
3 (a) to 3 (c) show an elevator type multilevel parking apparatus according to Embodiment 2, and this Embodiment 2 uses the lift device 16 employed as the turning device support means in Embodiment 1 above. This is a substitute for the fixed support base 28 having the support portion 28a, and other configurations are the same as those in the first embodiment, and therefore, the same components are denoted by the same reference numerals and detailed description thereof is omitted. However, in the second embodiment, since the turning device support means is the fixed support base 28 without a lifting function, the turning device 21 is received from the elevator lift 7 by the fixed support stand 28 by the lowering operation of the elevator lift 7. For this reason, the procedure for changing the direction of 180 ° by preparing the warehousing vehicle C for delivery is slightly different from that of the first embodiment, and the procedure will be described below.
[0041]
First, an empty pallet P is transferred from the storage shelf 9 to be stored to the elevator lift 7, and the elevator lift 7 is lowered to the floor 3a of the entry floor 3 as shown in FIG. At this time, the turning device 21 and the fixed support base 28 are separated from each other.
[0042]
Next, the movable deck 27 is rotated upward and held in a horizontal position, and after the floor 3a of the entry floor 3 and the pallet P on the elevator lift 7 are connected, the warehousing vehicle C is moved onto the pallet P by forward operation. Get in.
[0043]
Thereafter, as shown in FIG. 3 (b), the movable deck 27 is rotated downward so as not to interfere with the pallet P when the vehicle turns, and is held in a suspended position, and the elevator lift 7 is further lowered from this state. As a result, the support portion 28a of the fixed support base 28 is passed through the central opening 20 of the elevator lift 7 and the turning drive portion 23 of the turning device 21 comes into contact with the support portion 28a of the fixed support stand 28 from above. Supported, each engagement pin 24 engages with each engagement hole 25 from above. When the elevator lift 7 is further lowered from this state, the turning device 21 is supported by the fixed support stand 28, so that it is not lowered any further, and the incoming vehicle C is lifted from the elevator lift 7 together with the pallet P. It becomes.
[0044]
After that, the turning drive unit 23 of the turning device 21 is driven to prepare for delivery so that the incoming vehicle C can be turned 180 ° in the horizontal plane and exited by forward driving.
[0045]
Thereafter, as shown in FIG. 3C, the elevator lift 7 is raised. As a result, the turning device 21 is supported by the elevator lift 7 and lifted from the fixed support table 28, whereby each engagement pin 24 is detached from each engagement hole 25, and the fixed support table 28 is moved to the turning device 21. It is separated from the turning drive unit 23. From this state, the elevator lift 7 rises to the target storage shelf 9 and transfers the warehousing vehicle C to the storage shelf 9 together with the pallet P.
[0046]
In the case of exiting, as in the case of the first embodiment, the elevator lift 7 on which the exiting vehicle C is mounted together with the pallet P is lowered to the floor 3a of the entry floor 3, and the movable deck 27 is rotated upward. Then, after connecting the floor 3a of the entry floor 3 and the pallet P on the elevator platform 7, the unloading vehicle C may be withdrawn from the loading / unloading port 2 by forward driving.
[0047]
Therefore, in the second embodiment, the same operational effects as in the first embodiment can be achieved. In addition, since the swivel device 21 is transferred to the fixed support base 28 by the lowering operation of the elevator lift 7, the structure can be made as simple as it is not necessary to provide a lift device on the fixed support base 28 side. it can.
[0048]
In each of the above embodiments, the direction change of the vehicle C is the 180 ° turning type, but it may be a 90 ° turning type.
[0049]
【The invention's effect】
As described above, according to the present invention, the turning device is mounted on the elevator lift so as to be movable up and down so as to correspond to the central opening, and the turning device is installed in the pit corresponding to the entrance / exit of the elevator hoistway. Supporting means is provided, and when the vehicle turns, the turning device is supported by the turning device supporting means from below the central opening of the elevator lift and is moved up relative to the elevator lift so that the pallet moves up and down. The separation state of both was kept so as not to interfere with the table. Therefore, the structure of the elevator platform can be made simple and lightweight by the amount that the lift device is not mounted on the elevator platform, and the maintainability of the elevator platform can be improved, and the elevator platform can be suspended. It is possible to eliminate the excessive elongation of the wire rope and the adoption of a large capacity hoisting drive motor. Also, Since the pallet support area of the swivel of the swivel device is formed larger than the size of the central opening of the elevator lift so that the entire width direction of the pallet can be supported, When turning the vehicle, only the turning device support means passes through the central opening of the elevator platform, and the turning device passes. Without The size of the swivel device is not limited, the pallet can be stably supported with a wide pallet support area, and no reinforcing member is required. Further, since the horizontal movement is restricted by the restricting means while the turning device is supported by the turning device supporting means, the turning device is operated by the inertial force at the start of turning and at the end of turning. Can be eliminated, and the extremely low speed control of the swivel device can be eliminated, so that loading and unloading can be performed efficiently. Furthermore, since the central part of the swivel device is stably supported from below by the swivel device support means, there is no need for a nail as in the case where the periphery of the swivel device is supported by the nail, and there is a concern about the strength of the nail and the operation of the nail. A mechanism is unnecessary and a turning device support means can be made into a simple structure.
