[Industrial applications]

 The present invention relates to a mechanical parking facility.

[0002]

[Prior art]

 An elevator type is generally known as an example of a mechanical parking facility. This one is equipped with an elevator platform that puts a vehicle up and down, and multiple parking shelves that house the vehicle are arranged in multiple stages on both sides of the elevator shaft, and the lowest part of the elevator shaft is used for vehicle entry. It is formed in the above-mentioned section, and is designed to raise and lower the vehicle between the entry section and each parking rack of the parking section by the above-mentioned lifting platform.

In such an elevator parking facility, as described in Japanese Patent Laid-Open No. 2-85472, wire ropes connected to the front end and the rear end of the elevator are deflected above the ascending / descending path. It is usually wrapped around a car and then wrapped around the drum of the hoist. And in the thing of the same publication, the said drum is arrange | positioned at the side of the said hoistway.

[0004]

[Problems to be solved by the device]

 When the drum of the hoisting machine is not arranged right above the hoistway as in the above-mentioned conventional technique, the rope (wire rope or chain) connected to the front end of the ascending / descending platform and the rope connected to the rear end are The lengths from the drum (winding cylinder or sprocket) to the connecting point of the lift are often different. Therefore, when the vehicle is placed on the lift table and lifted up and down, the front part and the rear part of the lift table may deviate in height.

That is, since the amount of elongation of the above-mentioned rope due to elasticity is proportional to the length of the rope, when the ropes have different lengths as described above, the ropes when the vehicle is mounted on the lifting platform. The amount of expansion of the elevators differs from each other, which appears as a difference in height between the front part and the rear part of the lifting platform. This leads to a tilt of the lift and causes a positioning error when the lift is moved up and down to position it at a desired height, and between the lift and the parking shelves of the parking section. This will hinder the transfer of vehicles, and will also cause a difference in the service life of the ropes used for raising and lowering.

[0006]

[Means for Solving the Problems]

 To solve this problem, the present invention detects the front and rear wheel loads of a vehicle mounted on an elevator, and the wheel with the larger wheel load is placed on the side of the elevator where the shorter rope is connected. It is to be arranged.

That is, the first means for solving the above-mentioned problems (the invention according to claim 1) is to connect an elevator table on which a vehicle is mounted and a front end and a rear end of the elevator table in the vehicle entry direction. And a hoist for moving the hoisting platform up and down between the entry part and the parking part of the vehicle by feeding and hoisting these tethers, and from the drum of the hoisting machine to the hoisting platform. The front parking line and the rear parking line, which have different lengths to the front end and the rear end of the vehicle, are different from each other, and the front wheels of the vehicle are installed in the passenger compartment and mounted on the lift. And the load measuring means for measuring the load of each wheel of the rear wheels, the direction changing means for changing the direction of the vehicle provided in the riding section, and the wheel load measured by the load measuring means based on the front and rear of the vehicle. Out of the weight If the threshold side is not located on the side of the front and rear ropes of the elevator that is connected to the short rope, the positional relationship is changed before the vehicle is transported to the parking section by the elevator. And a control means for activating the direction changing means so as to be arranged.

A second means (the invention according to claim 2) is a development of the first means, wherein the parking section accommodates a vehicle together with a pallet, and Provided on the upper side of the vehicle, the direction changing means is provided on the boarding section, and includes a turntable for rotating the vehicle together with the pallet, and the lifting platform moves the vehicle up and down together with the pallet. In addition, a table hole is provided in the center for passing the turntable up and down, and the load measuring means are respectively provided on the turntable at intervals in the vehicle loading direction. Is constituted by a pair of load cells for detecting the vehicle through the pallet, and the control means has to change the direction of the vehicle before it is transferred to the parking section by the elevator. In this case, the above-mentioned direction changing means is operated so as to change the direction of the vehicle at the time of leaving.

A third means (the invention according to claim 3) is a development of the first means, wherein the parking portion accommodates a vehicle together with a pallet, and Provided on the upper side of the vehicle, the direction changing means is provided on the boarding section, and includes a turntable for rotating the vehicle together with the pallet, and the lifting platform moves the vehicle up and down together with the pallet. In addition, a table hole is provided in the center for passing the turntable up and down, and the load measuring means are respectively provided on the turntable at intervals in the vehicle loading direction. It is configured by a pair of load cells that detect the vehicle through the pallet, and whether or not the vehicle has been loaded into the pallet of the loading section by the forward movement. Vehicle direction detection means for detecting is provided, and the control means detects forward movement of the vehicle by the vehicle direction detection means and changes the direction of the vehicle before the vehicle is conveyed to the parking portion by the elevator. When the vehicle is not moving, or when the vehicle direction detecting means detects that the vehicle is moving backward, and the vehicle is being turned before it is transported to the parking section by the elevator, the vehicle is turned when the vehicle exits. There is a feature in that the above-mentioned direction changing means is operated so as to cause it.

[0011]

[Action]

 In the first means described above, when the larger side of the wheel loads before and after the vehicle to be parked is not arranged on the side of the elevator where the short rope of the hoisting machine is connected, parking by the elevator is performed. Before being conveyed to a section, the direction of the vehicle is changed so that the vehicle is placed in the above positional relationship. In this case, the elastic elongation of the rope depends on the length of the rope and the load acting on it, but since a large wheel load acts on the shorter one, the difference in the length of the rope is increased. The difference in elastic elongation caused by the difference is canceled by the difference in elastic elongation generated by the difference in wheel load. In other words, the height difference between the front and rear of the lift is small.

[0012] In the second means, at the time of warehousing, the turntable is passed through the table hole of the lift table so that the lift table is arranged at a relatively lower position than the turntable, and the pallet is placed on the turntable. Drive the vehicle forward. Then, when a pair of load cells detects the wheel loads of the front wheels and the rear wheels of the vehicle, and the side with the larger wheel load of the front and rear wheels is arranged on the shorter side of the front and rear ropes. Lifts the platform without changing the direction of the vehicle, picks up the vehicle together with the pallet from the turntable and raises it to the parking area. Then, in such a warehousing mode, when the warehousing is performed, the direction of the vehicle is changed by the turntable. Therefore, the vehicle can be embarked from the pallet by moving forward in the direction opposite to the direction when the vehicle is loaded.

When the wheel load side of the front and rear wheels is not arranged on the short side of the front and rear ropes, the vehicle is in that direction before being transported to the parking section, as in the case of the first means. The vehicle will not change direction when leaving the warehouse because it will be changed. Therefore, also in this case, the vehicle can be moved out of the pallet by moving forward.

The third means is to enable the vehicle to move out forward when leaving the vehicle, regardless of whether the vehicle is moved in forward or backward. Yes, vehicle direction detection means is provided for that purpose.

That is, it is necessary to change the direction of the vehicle at the time of leaving the vehicle, when the vehicle is moved in by the forward movement and the direction of the vehicle is not changed when the vehicle is moved in, and when the vehicle is moved in the backward movement. In addition, this is the case when the direction of the vehicle is changed at the time of storage. Then, in such a case, the vehicle can be moved out of the pallet by moving forward because the vehicle is turned around when the vehicle is unloaded.

[0016]

[Effect of device]

 Therefore, according to the first means, when the large side of the front and rear wheel loads of the vehicle is not arranged on the side of the elevator where the short rope of the hoisting machine is connected, Since the direction of the vehicle is changed so that the vehicle is placed in the above-mentioned positional relationship before transportation, the heavy side of the vehicle is placed on the side of the lifting platform to which the short cable is connected, and the length of the cable is shortened. It is possible to prevent the tilt of the lift by reducing the difference in the amount of elastic elongation caused by it, and to stop the lift at the desired position, and between the lift and the parking part of the parking area. It is possible to transfer the data smoothly and extend the useful life of each rope.

According to the second means, the parking section is arranged above the boarding section, the turntable is provided in the boarding section, and the pair of load cells for measuring the front and rear wheel loads of the vehicle are provided on the turntable. There is a table hole in the front of the vehicle so that when the larger of the front and rear wheel loads of the vehicle is located on the shorter rope side of the lift, the vehicle is turned around when leaving the vehicle. It is possible to obtain the effect that both the vehicle and the vehicle can be started by moving forward.

According to the third means, the vehicle orientation detecting means is provided in the entry section, forward entry of the vehicle is detected, and the larger side of the front and rear wheel loads of the vehicle is arranged on the short rope side of the elevator. If the vehicle is being driven backwards and the larger side of the front and rear wheel loads of the vehicle is not located on the short rope side of the elevator, the vehicle will change direction. Since the vehicle is carried out from time to time, the vehicle can be moved forward from the pallet when leaving the garage, regardless of whether the vehicle is moved forward or backward.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a tower-shaped parking structure that supports a mechanical parking facility, and an elevator platform 3 on which a vehicle V is mounted together with a pallet 2 is installed in a central portion of the parking structure 1. It is provided so that it can be raised and lowered. The lowermost part of the hoistway of the hoisting platform 3 is formed in the loading section 4 into which the vehicle is put in for parking, and the upper part of the hoisting section 4 is along the hoistway and has a number of parking shelves 5 on both sides thereof. Is formed in the parking portion.

The elevating table 3 has a rectangular shape, and front and rear ropes (wire ropes) 6a and 6b are connected to a total of four positions at both ends of a front end and a rear end in the vehicle entry direction. It As shown in FIG. 2, the front and rear cords 6a and 6b are wound around the front and rear deflecting wheels 7a and 7b arranged on the ceiling portion of the parking structure 1. In the case of this example, the drum 9 of the hoisting machine 8 is arranged beside the front shifting wheel 7a. For this reason, the rear rope 6b wound around the rear deflector 7b is further wound around the second deflector 7c arranged near the front deflector 7a, and together with the front rope 6a. The balance weight 12 is hung around the drum 9 and the balance weight 12 is suspended via the idle 11 at the end.

Therefore, the length of the front side cord 6a from the drum 9 of the hoisting machine 8 to the front end of the lift table 3 is larger than the length of the rear side cord 6b from the drum 9 to the rear end of the lift table 3. It's getting shorter.

As shown in FIG. 3, the parking structure 1 is formed with an entrance / exit opening 13 that opens in the entrance direction with respect to the entrance part 4, and the entrance / exit opening 13 is provided with a door 14. A pit 15 is formed below the hoistway in the entry section 4, and a directional change means 16 for changing the direction of the vehicle is provided in the pit 15. The direction changing means 16 includes a turntable 17 on which the vehicle V is placed and rotated together with the pallet 2, and a front wheel load and a rear wheel load of the vehicle V are applied to the turntable 17 via the pallet 2. A pair of load cells (load measuring means) 18a, 18b for detecting each of them are provided at a distance in front of and behind in the vehicle entry direction.

The direction changing means 16 is provided with a rotational position sensor for the turntable 17 in order to detect which of the pair of load cells 18a, 18b is arranged forward in the boarding direction. Has been.

In addition, a table hole is formed in the center of the lift table 3 to pass the turntable 17 of the direction changing means 16 up and down. In this case, the elevator 2 is lowered further than the turntable 17 so that the pallet 2 is passed from the elevator 3 to the turntable 17, and the elevator 3 is lifted to turn the pallet from the turntable 17 to the pallet 3. 2 will be passed.

Further, as shown in FIG. 4, the loading section 4 has a first optical sensor as a vehicle direction detecting means for detecting whether or not the vehicle V is loaded on the pallet 2 of the turntable 17 by forward movement. And a second optical sensor.

That is, the first photosensors are arranged at a front and rear interval so that the light reception is blocked by the door Vd when the door Vd on the right side in the vehicle V entry direction is released. It is composed of a light projector 21a and a light receiver 21b. Further, the second optical sensor is provided with a light emitter 22a and a light receiver 22a, which are arranged at a front and rear so that light reception is blocked by the left door when the left door when viewed in the vehicle V entry direction is released. 22b and.

The vehicle direction detection means assumes that the driver's seat of the vehicle V is on the right side, and when the first optical sensors 21a and 21b detect the opening of the door, the vehicle V is put in by the forward movement. When the second optical sensors 22a and 22b detect the opening of the door, it can be determined that the vehicle V has been entered by the reverse drive.

Then, as shown in FIG. 5, the mechanical parking equipment is provided with a direction changing means based on the outputs of the load cells 18a, 18b, the first optical sensors 21a, 21b and the second optical sensors 22a, 22b. Control means 23 for controlling the operation of 16 are provided. That is, the control means 23, when the rear side of the front and rear wheel loads of the vehicle V is larger when the vehicle V is stored, and when the vehicle V is facing forward in the boarding direction when the vehicle is stored, Each of the above-mentioned direction changing means 16 is operated so as to change the direction of the vehicle.

The control flow of the direction changing means 16 at the time of storage by the control means 23 is shown in FIG. 6, and the outputs of the load cells 18a, 18b, the first optical sensors 21a, 21b and the second optical sensors 22a, 22b. Is read, and when the vehicle V is getting in by moving forward, the flag process of F ← 1 is performed (steps S1 to S3). This flag F is for determining whether or not the vehicle V is facing forward in the entry direction when leaving the garage. When F = 1, the vehicle is facing forward in the entry direction. When the wheel load on the rear side in the riding direction is larger than that on the front side, the direction of the vehicle V is changed, and the direction of the vehicle is changed by the direction change, so the reversal process of the flag F is performed. (Steps S4 to S6).

The control flow of the direction changing means 16 at the time of leaving the vehicle by the control means 23 is shown in FIG. 7. When the flag F is read and F = 1, the direction of the vehicle V 1 is changed. Is performed (steps S7 to S9).

Therefore, in the above-described embodiment, in both forward and backward entry of the vehicle V, the vehicle V is changed in direction when the wheel load on the rear side in the entry direction is larger, The pallet 2 is lifted up and conveyed by the lifting platform 3 to the position of the planned parking rack 5, and is stored in the parking rack 5.

Therefore, when the vehicle V is raised by the elevating table 3, a larger load acts on the short front side rope 7a of the hoisting machine 8 than on the long rear side rope 7b. Therefore, the difference in elastic elongation caused by the difference in length between the ropes 7a and 7b is canceled by the difference in elastic elongation caused by the difference in wheel load, and the difference in height between the front part and the rear part of the lifting table 3 is reduced. The size is reduced, and it becomes easy to stop the lift 3 at a desired position, and the transfer of the vehicle V between the lift 3 and the parking rack 5 can be smoothly performed.

In addition, even when the vehicle V is transferred from the parking rack 5 to the lift 3 at the time of exit, a larger load is applied to the short front rope 7a than to the long rear rope 7b. Therefore, the height difference between the front part and the rear part of the lifting table 3 becomes small, and the stopping of the lifting table 3 at the loading section 4 becomes easy. Then, in the entry section 4, when the flag F = 1, that is, when the vehicle V is facing forward in the entry direction, the direction change means 16 operates to change the direction of the vehicle V. The driver can get the vehicle V out of the pallet 2 by driving forward.

The above embodiment is an example in which the vehicle can be loaded into the pallet 2 at the time of warehousing either forward or backward, but when the loading is limited to forward only, , The flag F = 1 is processed only when the vehicle is not turned at the time of warehousing, and whether or not the vehicle is to be turned is determined depending on whether F = 1 at the time of warehousing. You can do it like this.
