Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a vehicle detection device for a mechanical parking facility.

[0002]

[Prior Art]

 As a vehicle detection device for a mechanical parking facility, a device that projects a light beam or an ultrasonic wave to a passenger compartment where a vehicle is parked for parking to detect the presence or absence of a vehicle, particularly the presence or absence of a vehicle protruding from a specified size range is generally used. It is known (see Japanese Examined Patent Publication No. 57-61869). That is, for example, when the door mirror is protruding or the door of the vehicle is opened, it may come into contact with the structure of the parking facility when the vehicle is transported from the entry section to the parking section. In order to prevent this, the presence or absence of the above-mentioned vehicle protrusion is detected.

[0003]

[Problems to be solved by the device]

 By the way, for example, the mounting position of the door mirror differs depending on the vehicle type. Therefore, in order to reliably detect the presence or absence of the protrusion of the door mirror, it is desirable that the vehicle sensor itself is large, that is, the detection width is wide. However, when the vehicle sensor becomes large, it causes a problem that it interferes with the vehicle transportation means passing through the sensor mounting position. Therefore, in practice, use a method that widens the detection width while providing multiple small sensors so as not to interfere with the vehicle transportation means, or use a large sensor to add space for the passenger compartment. In the case of the former, the position adjustment of each sensor becomes troublesome, and in the case of the latter, a large design change of the conventional parking equipment is required and a wasteful space is produced. Even so, there is a feeling that the cost is high.

[0004]

[Means for Solving the Problems]

 In order to solve this problem, the present invention supports the vehicle sensor on a support member beside the transportation path of the vehicle transportation means so that when the presence or absence of a vehicle is detected, the vehicle sensor is projected onto the transportation path, and When moving the vehicle, the vehicle sensor is retracted to the side of the transportation path.

That is, a concrete means includes a vehicle carrying means for carrying a vehicle and carrying the vehicle, and a machine provided with a boarding section on which a vehicle is parked for parking a vehicle on a carrying route of the vehicle carrying means. A vehicle detection device for a parking system, comprising: a detection member projecting on the above-mentioned conveyance path on a supporting member on the side of the above-mentioned conveyance path to detect the presence or absence of a vehicle by projecting a light beam or an ultrasonic wave to the entry section. A vehicle sensor that is movably supported between a retracted position that is retracted to the side of the transport path to allow movement of the vehicle transport means, and the vehicle sensor detects the presence or absence of a vehicle in the entry section. And driving means for driving the vehicle transportation means to move to the retracted position when the vehicle transportation means moves on the transportation path.

[0006]

[Action]

 In the above vehicle detection device, when the vehicle is detected in the entry section, the vehicle sensor can be made to project onto the conveyance path, so that it is easy to project light rays or ultrasonic waves at a proper position for vehicle detection in the entry section. become. When the vehicle conveying means moves on the conveying path, the vehicle sensor can be retracted to the side of the conveying path, so that the interference between the vehicle sensor and the vehicle conveying means can be avoided.

[0007]

[Effect of the device]

 Therefore, according to the present invention, the vehicle sensor is supported on the supporting member on the side of the transportation path of the vehicle transportation means, and when the vehicle sensor detects the presence or absence of the vehicle in the entry section, the vehicle sensor is projected onto the transportation path and the vehicle transportation means. When the vehicle moves, it is evacuated to the side of the transportation path, so even if a relatively large vehicle sensor is used, there is a problem of interference between the vehicle sensor and the vehicle transportation means without enlarging the space for the passenger compartment. It is possible to project light rays or ultrasonic waves to a position suitable for vehicle detection of the above-mentioned entry part while solving the above, and thus it is possible to increase the detection width by using a large sensor, Since it is not necessary to use a small sensor, the sensor mounting and position adjustment work is simple and cost can be reduced.

【Example】

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

This example relates to an elevator parking facility. In FIGS. 1 and 2, reference numeral 1 denotes a vehicle lift (vehicle carrying means) on which a vehicle W is mounted and which moves up and down. A large number of parking shelves 21 for accommodating vehicles W for parking are arranged on both sides of the vehicle hoistway 2 by the vehicle hoisting base 1 in multiple stages along the hoistway 2, and The lower part is formed in the loading section 3 for loading the vehicle W for parking. The vehicle elevating platform 1 is for elevating and lowering a vehicle W on a pallet 4, and each parking shelf 21 accommodates the vehicle W together with the pallet 4.

Then, a supporting frame 5 is erected on the side of the hoistway 2 and the supporting frame 5 is provided with or without the vehicle W of the riding section 3, in this case, the door mirror of the vehicle W is riding. A light projecting side sensor 6 for detecting whether or not it projects beyond the specified width of the receiving portion 3 is supported. The upper end of the support frame 5 is connected to the beam 8 extending between the columns 7 and 7. On the other hand, a pit 9 is formed under the boarding section 3, and a light receiving side sensor 11 corresponding to the light projecting side sensor 6 is supported by a support base 10 standing on the bottom of the pit 9. 1 and 2, reference numeral 12 is a wire rope that suspends the vehicle lift 1 for lifting.

The support structure of the light-projecting side sensor 6 is shown in FIGS. 3 to 5.

The light emitting side sensor 6 has its lower end pivotally supported by the support frame 5 via a bracket 13, while its upper end passes through a bracket 14 and first and second arms 15 and 16 to reducer. It is connected to the output shaft of an attached drive motor 17, and by the operation of this drive motor 17, it moves to the detection position when detecting the vehicle in the entry section 3, and when the vehicle lift 1 moves in the hoistway 2. It is designed to move to the retracted position.

That is, as shown in FIG. 4, the detection position is inclined such that the light-emission-side sensor 6 has its lower end as a fulcrum so that the upper end projects above the hoistway 2, and the detection light beam is hoisted. It is a position along which the image is projected toward the light-receiving side sensor 11. Further, in the retracted position, as shown in FIG. 5, the upper end of the light emitting side sensor 6 is moved to the support frame 5 so that the light emitting side sensor 6 is along the support frame 5 and passes through the hoistway 2. It is a position retracted to the side of the hoistway 2 so as not to interfere with the vehicle lifting platform 1.

Here, the moving mechanism of the light projecting side sensor 6 will be described. One end of the first arm 15 is pivotally attached to the bracket 14 at the upper end of the light projecting side sensor 6, and the other end is the second arm. It is pivotally attached to one end of 16. The other end of the second arm 16 is connected to the output shaft of the drive motor 17, and is rotated by the operation of the drive motor 17. A guide arm 18 is provided to regulate the movement mode of the light-projecting side sensor 6. That is, the guide arm 18 has a guide hole 18a extending in the longitudinal direction, one end of which is pivotally attached to the support frame 5, and the guide hole 18a is provided with the first arm 15 and the second arm 16. The pivot shaft 19 is engaged.

In this case, the light projecting side sensor 6 moves to the detection position and the retracted position by the rotation of the second arm 16 by the operation of the drive motor 17, but the guide arm 18 does not move the light projecting side sensor 6. It acts as a stopper that regulates the detection position, and also prevents the light projecting side sensor 6 from moving in the direction opposite to the rotation direction of the second arm 16.

Therefore, in the case of the above elevator type parking equipment, when detecting the protrusion of the door mirror of the vehicle W placed on the vehicle lift 1 of the entry section 3, the projection side sensor 6 is used as the detection position for detection. It is possible to widely project the light rays to appropriate positions for detecting the presence or absence of the projection of the door mirror. When the vehicle lift 1 moves along the hoistway 2, the light projecting side sensor 6 can be set to the retracted position to avoid interference between the light projecting side sensor 6 and the vehicle lift 1.

In the above embodiment, the light emitting side sensor is movable and the light receiving side sensor is fixed, but the arrangement may be reversed.

As the vehicle sensor, an ultrasonic sensor that emits ultrasonic waves and detects the vehicle based on the presence or absence of reflection of the ultrasonic waves may be used instead of the above optical sensor. However, the present invention is not limited to this, and may detect whether or not other parts of the vehicle protrude beyond the specified range, or whether or not the vehicle itself exists in the entry section.

Further, the present invention is not limited to the above elevator type parking equipment, the chain is suspended on the sprockets arranged above and below, and the cage for vehicle mounting is suspended in a chain form on the chain, and is placed on the transportation path of the cage. It is equipped with a vertical circulation parking facility that forms a vehicle entry area, and a rectangular horizontal circulation transportation path that transports a vehicle on a pallet, for example, with a vehicle entry area on the transportation path or above the transportation path. It is needless to say that the invention can be applied as a vehicle detection device for other mechanical parking equipment such as a horizontal circulation parking equipment in which a vehicle entrance portion is provided and the transportation path and the entrance portion are connected by vehicle elevating and conveying means.
