Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulation type parking facility, and more particularly to a so-called circular circulation type parking facility in which a pallet is circularly moved between two upper and lower horizontal planes by endless circulation movement means.

[0002]

2. Description of the Related Art Circular mobile parking equipment, especially so-called circular circulating mobile parking equipment in which a pallet circulates between two upper and lower horizontal planes, is disclosed in Japanese Patent Laid-Open No. 2-27069. An endless chain that wraps around a pair of sprockets that are spaced apart from each other and that circulates in a vertical plane, and a plurality of pallets are held in the endless chain by a holding arm that is provided in the endless chain, and the endless chain circulates. Accordingly, the pallet is circularly moved between the upper and lower horizontal planes.

A pair of rails is provided above and below the endless chain to support the pallet when the pallet horizontally moves. The pair of rails supports the pallet being horizontally moved. There is.

On the other hand, when the pallet is moved up or down, all the weight of the pallet including the vehicle is received by the circulation moving means. Therefore, the weight of the vehicle W mounted on the pallet acts as a weight load on the motor that drives the endless chain, and particularly when the pallet is moved upward, a large weight load acts.

Since the weight of the vehicle mounted on the pallet varies, the maximum weight of the vehicle that can be mounted on the pallet (maximum loading weight of the pallet) is set to a certain value, and the maximum loading weight of the pallet can be allowed by the motor. The weight load (allowable load) of the vehicle is set, and the required power of the motor is set based on this allowable load.

[0006]

By the way, in the actual operation of the above-mentioned circular circulation type parking facility, it is sometimes strongly desired to store a vehicle exceeding a small allowable load for various vehicles. It is required that the maximum payload be as large as possible so that a heavy vehicle can be parked.

In response to such a request, if the weight of the vehicle exceeds the maximum loading weight of the pallet, the weight load at that time exceeds the value of the allowable load, so that a large vehicle exceeding the maximum loading weight is accepted at all. I can't. In order to be able to accept the heavy vehicle,
The required power of the motor had to be increased.

The present invention has been made in view of the above point, and installs a pallet capable of mounting a vehicle corresponding to an allowable load and exceeding a mounting weight without increasing the required power of a motor for driving an endless chain. The purpose is to be able to.

[0009]

In order to achieve the above-mentioned object, the present invention provides a weight that moves downward with the downward movement of one of a predetermined pair of pallets, and another upper weight is provided. By reducing the weight load of a vehicle placed on a pallet, it is possible to mount a vehicle that exceeds the loading weight corresponding to the allowable load determined by the power required to drive the circulating means on another pallet. is there.

[0010] Specifically, a solution means taken by the invention according to claim 1 is that a plurality of pallets on which a vehicle is mounted and a pair of rotating bodies provided separately in the horizontal direction are wound around and endless in a vertical plane. A circulation type having a circulation moving means for circulating movement to each of the plurality of pallets and a pair of upper and lower rails for placing and supporting the pallets when the pallets horizontally move. Targeting parking equipment, one pallet of a pair of pallets provided at positions symmetrical to each other with respect to a predetermined point between the pair of rotating bodies is placed on another pallet that moves upward. A weight is provided to reduce the weight load of the vehicle.

Further, the solution means taken by the invention according to claim 2 is a state in which a plurality of pallets on which a vehicle is mounted and a pair of rotating bodies provided separately in the horizontal direction are wound around and hold the plurality of pallets. And a pair of upper and lower rails for mounting and supporting the pallet when the pallet moves horizontally, in which the pallet moves endlessly on a vertical plane in an endless manner. Of a circulating movement means for holding one pallet of a pair of pallets provided at positions symmetrical to each other with respect to a predetermined point between the pair of rotating bodies. The part is provided with a weight that reduces the weight load of the vehicle placed on another pallet that moves upward.

[0012]

With the above construction, in the invention according to claim 1,
A plurality of pallets are circulated and moved by the circulatory moving means. When one pallet of a pair of pallets provided at positions symmetrical with respect to a predetermined point between the pair of rotating bodies of the circulation moving means moves downward on the side of one rotating body, The pallet moves to the side of the other rotating body. The weight provided on one pallet reduces the weight load of the vehicle placed on the other pallet that moves upward. Therefore, a vehicle having a weight corresponding to the weight of the weight can be mounted on the other pallet, and the maximum weight (maximum loading weight) of the vehicle that can be mounted on the other pallet is when the weight is not provided on one pallet. It will be larger than that.

In the invention according to claim 2, a weight is provided at a portion of the circulation moving means for holding one pallet of the pair of pallets. The weight is increased by the weight of the weight as compared with the case where the weight is not provided on the pallet having one load.

[0014]

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

FIG. 1 shows a circulation type parking facility according to a first embodiment of the present invention. The circulation type parking facility is a so-called circular circulation type parking facility, and includes eight pallets 3A, 3B, 5A, 5 on which a vehicle W is mounted between two upper and lower horizontal planes.
B, 7A, 7B, 9A, 9B are configured to be circulated.

Specifically, the above-mentioned circulation type parking facility is provided with two rows of endless chains 1 as a circulation moving means in the front-rear direction. The two rows of endless chains 1 are wound around sprocket wheels 11A and 11B as a pair of rotating bodies, which are provided separately in the horizontal direction (left and right direction in the figure), and are circularly moved in a vertical plane. There is.

On the other hand, between the two rows of endless chains 1, 8
Individual pallets 3A, 3B, 5A, 5B, 7A, 7B, 9
A and 9B are arranged, and two predetermined two out of eight are provided at positions symmetrical with respect to a predetermined point T between the pair of sprockets 11A and 11B to form pairs. One of the three pallets 3A, 5
When A, 7A and 9A are located on the side of one sprocket 11A, the other pallets 3B, 5B, 7B and 9B are located on the side of the other sprocket 11B.

The endless chain 1 has eight holding arms 1.
, And each of the holding arms 13 engages with one side portion of the lower surface of the corresponding pallet 3A, ... to hold eight pallets 3A ,. Are configured to cyclically move each of the eight pallets 3A ,. The pallet 3 is provided on the side of the pair of sprockets 11A and 11B in the horizontal movement direction.
A pair of horizontal supporting arms 15, 15 for supporting the other side of the lower surface of A, ... Is provided.

Another sprocket 1 around which the endless chain 1 is wound by a chain drive is mounted on the circulation type parking facility.
A motor 17 is provided for driving the 1B and the horizontal supporting arm 15 to rotate simultaneously. The holding arm 13 and the horizontal supporting arm 15 provided on the endless chain 1 are simultaneously rotated at the same rotation angle by the drive of the motor 17, and when the pallets 3A, ... ,… Are kept horizontal.

When the pallets 3A, ... Are moved up, the weight of the vehicle W mounted on the pallets 3A ,. The required power of the motor 17 is
Weight load of the vehicle W that the motor 17 can tolerate (allowable load)
Is set to be 1700 kg, for example.

Above and below the endless chain 1, a pair of upper and lower rails 19, which extend in the horizontal movement direction of the endless chain 1 and mount and support the pallets 3A, ... When the pallets 3A ,. 19 are provided. The pair of upper and lower rails 19 is configured so that a pair of upper and lower rollers 21 and 21 provided on the pallets 3A, ...

One pallet 3A of the pair of pallets 3A, 3B is provided with a weight 23 for reducing the weight load of the vehicle W placed on the other pallet 3B moving upward. The weight of the weight 23 is set to 200 kg, for example.

Next, in the above circulation type parking facility, 17
The operation when the vehicle W having an allowable load of 00 kg is mounted on another pallet 3B will be described. Particularly, when the vehicle W is placed on the other pallet 3B moving upward and the vehicle W is not placed on the one pallet 3A moving downward, the motor 1
Since the weight load of the vehicle W on the vehicle 7 becomes the maximum, this case will be described.

In FIG. 1, one pallet 3A provided with a weight 23 is located to the side (left side in the figure) of one sprocket 11A moving downward, and the other pallet 3A is not provided. The pallet 3B is located laterally (to the right in the drawing) of the other sprocket 11B that moves upward.

Weight 23 provided on one pallet 3A
(200 kg) reduces the weight load of the vehicle W placed on another upward moving pallet 3B by 200 kg. Therefore,
If the allowable load is 1700 kg, the maximum weight of the vehicle that can be loaded on the other pallet 3B (maximum loading weight) is 17
It is 1900 kg, which is 200 kg more than 00 kg. When the vehicle W is placed on the one pallet 3A, the weight load on the motor 17 is further reduced by the weight of the vehicle W acting as a weight.

On the other hand, in a pair of pallets in which the weight 23 is not provided on one pallet 3A, for example, 5A and 5B, the weight load is not reduced by the weight 23 on the other pallet 5B, so that the maximum weight of the other pallet 5B is reduced. The loading weight is 1700 kg, which is the same as the allowable load.

According to this embodiment, one pallet 3A has two pallets.
By providing a weight 23 of 00 kg, the maximum load weight (1
It is possible to provide another pallet 3B capable of mounting a vehicle W of 1900 kg exceeding 700 kg). Therefore, the parking facility can be adapted to the parking of the heavy vehicle W, and the actual operation of increasing the maximum weight of the other pallet 3B can be performed as much as possible.

Further, in one pallet 3A, the maximum loading weight is reduced by the amount of the weight 23 having a weight of 200 kg provided.
Although it is 500 kg, since there are vehicles W of various weights, having one pallet 3A with a small maximum loading does not hinder, and even if the maximum loading weight of one pallet 3A decreases, other pallets can be used. Increasing the maximum loading weight of 3B is useful because the parking facility can accommodate vehicles W of various weights.

Next, a second embodiment of the present invention will be described. Although not shown, in the present embodiment, the weight 23 is used as a part of the circulation moving means for holding one pallet 3A of the pair of pallets 3A, 3B, that is, in the vicinity of or for holding one pallet 3A in the endless chain 1. It is provided on the arm 13. According to this embodiment, the same operational effect as the first embodiment can be exhibited.

As for the installation position of the weight including the first and second embodiments, one pallet 3A, one pallet 3A in the endless chain 1 and at least one of the holding arms 13 are provided. I wish I had it.

[0031]

As described above, according to the invention of claim 1, one of the pair of pallets provided at positions symmetrical to each other with respect to a predetermined point between the pair of rotating bodies. A weight is provided on the pallet to reduce the weight load of the vehicle placed on another pallet that moves upward by the weight, and the maximum load weight of another pallet can be increased by the weight of the weight. Therefore, it is possible to install a pallet capable of mounting a vehicle that exceeds the mounting weight corresponding to the allowable load without increasing the required power. Therefore, the parking facility can be adapted to the parking of a heavy vehicle to match the actual operation.

According to the second aspect of the present invention, the weight is provided at the portion of the circulation moving means for holding one of the pair of pallets, and the maximum loading weight of the other pallets is one. As compared with the case where the pallet is not provided with a weight, the weight is increased by the weight, and like the first aspect, a pallet capable of mounting a vehicle exceeding a mounting weight corresponding to an allowable load is installed without increasing required power. be able to.
