DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a mechanical parking device, and more particularly, to a device for surely stopping a vehicle entering a storage berth at a predetermined position.

[0002]

2. Description of the Related Art At present, there are various types of mechanical parking devices. Among them, a type in which a traveling cart is used for delivery of a vehicle between a parking room and the outside is excellent in operation efficiency and the number of vehicles that can be accommodated. Is the best thing to increase.

As shown in FIGS. 9 to 11, the mechanical parking device is often installed in an underground portion of a building 1, such as an office building, a store, a warehouse, or the like. And, in order to be able to accommodate more vehicles inside, it is formed by combining a plurality of units 2, 3 and the like arranged side by side. These units 2 and 3 are configured as follows.

[0004] Inside one unit 2, a traveling path 4
And a traveling rail 6 of a traveling vehicle 5 erected on the traveling path 4.
And a plurality of parking rooms 7 arranged in tandem on both left and right sides of the traveling path. Each parking room 7 is formed on parking shelves 8 (FIG. 11) arranged in multiple stages (for example, two stages), and a plurality of traveling vehicles 5 are arranged in the traveling path 4 corresponding to each parking shelf 8. Have been. The unit 3 is also the same as the unit 2
And its description is omitted.

On the other hand, an entrance / exit passage 10 is provided on the first floor of the building 1 and the like, and an entrance room 11 having an entrance berth, which will be described later, and an exit room 12 are arranged in the middle thereof. And
The storage room 11 and the storage room 12 are connected to the unit 2 by the elevating device 13. In addition, the traveling carriage 5, the parking room 7, the entrance room 11, the exit room 12, and the elevating device 13 are provided with a front-wheel traverse conveyor 14 and a rear-wheel traverse conveyor 15 for transferring vehicles between each other. doing. By the way, as shown in FIG. 9 and FIGS.
Is wider in the front-rear direction with respect to the front-wheel lateral feed conveyor 14. This is to accommodate different vehicles with different wheelbases. In the conventional mechanical parking device, the front wheel of the vehicle 9 is used by being positioned at a predetermined position of the front-wheel lateral feed conveyor 14. At this time, since the rear wheel position differs depending on the wheelbase,
The rear-wheel lateral feed conveyor 15 is formed to be long so as to absorb the difference in the rear wheel position.

The unit 3 has a storage room 11,
The retrieval room 12 and the elevating device 13 are shared with the unit 2. Then, by communicating between the lifting device 13 and the traveling carriage 5 of the unit 3 by the front and rear transfer traverse conveyors 14 and 15 for the transfer chamber 16 provided for transfer between the units, the vehicle 9 Delivery has been done. The traveling trolley 5, the parking room 7,
The front and rear wheel lateral feed conveyors 14 and 15 provided in the entrance room 11, the exit room 12, the elevating device 13 and the transfer path 16, respectively, can be rotated in synchronization with each other when the vehicle 9 is delivered. Yes, delivery of vehicles can be performed smoothly.

FIG. 12 shows the traveling carriage 5. As shown, the traveling vehicle 5 includes a main frame 18 and can travel on the traveling rail 6 by traveling wheels 17.
The main frame 18 has a traverse conveyor 14 for front wheels,
The rear-wheel lateral feed conveyor 15, the traveling motor 19, and the like are mounted. By driving the traveling wheels 17 with the traveling motor 19, the vehicle can travel on the rail 6 by itself. Further, the front wheel lateral conveyor 14 is provided with a front wheel stopper 20 for holding the front wheel 9a of the vehicle 9. The front wheel stopper 20 is for preventing the vehicle 9 from falling off when the hand brake is not applied to the vehicle 9.

FIGS. 13 and 14 show a storage berth 21 provided in the storage room 11. As shown, storage berth 21
The front and rear wheel side feed conveyors 14 and 15 are arranged on substantially the same plane as the floor surface 22 of the storage room, and a passage 23 higher than the floor surface 22 is provided in front of and side of the floor surface 22. (For moving people). Further, the front-wheel lateral feed conveyor 14 of the storage berth 21 has a transfer surface (upper surface) having a flat flat portion 14a and an inclined portion 14b whose transfer surface becomes higher toward the end. In FIG. 13, a plurality of arrows shown on the front-wheel lateral feed conveyor 14 schematically show how the inclination angle of the shaft of the conveyor roller gradually increases at the inclined portion 14b. This inclined portion 14b
It has a role as a display means for indicating the stop position of the vehicle.

At the time of storage, the vehicle 9 enters the storage berth 21 while moving forward in the direction of arrow C. Then, when the front wheel 9a reaches the inclined portion 14b of the front-wheel lateral feed conveyor 14, the front wheel gradually climbs the inclined portion 14b. At this time, the driver of the vehicle can recognize that the vehicle has reached the stop position without feeling a strong impact. Then, after the vehicle 9 is stopped at a predetermined position, the front and rear wheel lateral feed conveyors 14 and 15 are driven to move the vehicle 9 in the direction shown by the arrow D, and the elevating device 13 (FIGS. 11)).

[0010]

The mechanical parking device having the above configuration has the following problems. The stop position of the vehicle 9 is determined based on the front wheels 9a.
Therefore, a vehicle having a front overhang longer than a range assumed in advance may collide with a parking device at the time of delivery of the vehicle, and the device cannot be used. In addition, assuming that the vehicle 9 is not subjected to the hand brake, a traverse conveyor for the front wheels of the traveling vehicle 5 is used.
14 has a front wheel stopper 20.
Due to the 20 installation spaces, the width of the front-wheel traverse conveyor 14 in the front-rear direction is also practically limited. Further, since the front wheel stopper 20 becomes a protrusion on the carrier of the traveling vehicle, it is necessary to limit the minimum ground clearance of the vehicle that can be mounted. Therefore, in the conventional mechanical parking device, a device for determining the minimum ground clearance has become indispensable. When discriminating a vehicle that cannot be parked as described above, if the applicant uses the vehicle type discriminating device disclosed in Japanese Patent Application Laid-Open No. 9-217514, it is possible to determine the suitability of the vehicle with high accuracy. . However, in order to reduce equipment costs and operation costs and to improve the usability of the apparatus, further simplification of the entire apparatus has been desired.

The present invention has been made in view of the above problems, and an object of the present invention is to improve the usefulness of a mechanical parking device by rationalizing the entire device and reducing costs. .

[0012]

According to a first aspect of the present invention , there is provided a vehicle, comprising: a plurality of parking rooms arranged along a traveling path of a traveling vehicle; In a mechanical parking device provided with a traverse conveyor for transferring vehicles in a direction crossing the traveling path in each of the car room and the parking berth, the parking area or running range of the parking room is provided.

Further, in the invention according to claim 2 of the present invention, the traverse conveyor includes a front-wheel traverse conveyor and a rear-wheel traverse conveyor having the same width and arranged in parallel. It is desirable to become.

In the present invention, in the approach direction of the vehicle,
The stop position of the vehicle (the stop position of the wheel) can be changed by the movable stop . Therefore, even if the widths of the front wheel traverse conveyor and the rear wheel traverse conveyor are the same, by changing the stop position of the vehicle, the front and rear wheels of various vehicles having different wheelbases can be moved forward and rearward. It is possible to reliably place it on the rear conveyor. In addition, by sharing the front and rear wheel traverse conveyors, cost reduction and uniform load conditions of the front and rear wheel conveyors are achieved.

[0016] In the invention according to claim 3 of the present invention ,
It is also possible that the vehicle type discriminating device is installed in a storage berth, and that the front and rear wheel traverse conveyors of the storage berth are installed so as to be movable in a vehicle entering direction. Then, when the vehicle enters the storage berth, the suitability of parking and the vehicle stop position at the storage berth are simultaneously determined.

[0017]

Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, the same or corresponding portions as in the conventional example are denoted by the same reference numerals, and detailed description thereof will be omitted.

FIG. 1 shows a storage berth 21 of a mechanical parking device according to a first embodiment of the present invention, and a vehicle 9 positioned at the storage berth 21. In the present embodiment, a front-wheel traverse conveyor 14 and a rear-wheel traverse conveyor 15 having the same width are used. Side wheel conveyor 14 for front wheels
Is provided with a bollard 23 that indicates the stop position of the vehicle . Car stop
A roller 23a is provided on the lower surface of 23, and an actuator is provided.
It is supported by 24 push rods 25. Therefore, with the operation of the actuator 24, the wheel stop 23 can move in the approach direction of the vehicle (the left-right direction in FIG. 1). Further, the actuator 24 includes a position detecting unit 26, a load detecting unit 27, and a buffering unit 28.

Here, an example of a method of using the storage berth 21 and the car stop 23 having the above-described configuration will be described with reference to FIG. As shown in FIG. 2A, when the vehicle 9 to be stored is a vehicle having a relatively long wheelbase (a large passenger car or the like), the vehicle stop 23 is placed in front of the front-wheel lateral feed conveyor 14 (the left side in FIG. 2). Position. In this state, storage berth 21
When the front wheel 9a of the vehicle 9 that has entered the vehicle comes into contact with the vehicle stop 23, the driver of the vehicle 8 knows the stop position of the vehicle. Under this condition, the rear wheels 9b of the vehicle 9 are located on the rear-wheel lateral feed conveyor 15.

Further, if the form of the vehicle is grasped in advance by a vehicle type discriminating device to be described later, the front and rear wheels 9a and 9b can be used for the front and rear wheels even if the front overhang or the rear overhang of the vehicle 9 is excessive. Traverse conveyor 14,
The stop position of the vehicle 9 can be adjusted by moving the wheel stop 23 within a range in which the vehicle 9 does not fall off, so that the vehicle 9 can be stored. After the vehicle 9 is stopped at a predetermined position as described above, the wheel stop 23 can be evacuated outside the front-wheel lateral feed conveyor 14 so as not to hinder the delivery of the vehicle.

As shown in FIG. 2 (b), when the vehicle 9 to be stored is a vehicle having a relatively short wheelbase (light vehicle, etc.), the bollard 23 is provided with a greater degree than in the case of FIG. 2 (a). Position backward. Then, the rear wheel 9b is placed on the rear-wheel traverse conveyor 15 by moving the stop position of the vehicle backward. Also in this case, if the vehicle type is grasped in advance by a vehicle type discrimination device described later, the vehicle 9
Even if the front overhang or the rear overhang is excessive, the vehicle 9 is stopped by moving the wheel stop 23 within a range in which the front and rear wheels 9a, 9b do not fall off from each of the front / rear wheel traverse conveyors 14, 15. The position can be adjusted to enable storage.

The operation and effect obtained from the first embodiment of the present invention having the above configuration are as follows. The bollard 23 provided on the entrance berth 21 is movable in the front-rear direction by controlling the actuator 24, and the stop position of the vehicle 9 can be freely set. Therefore, wheelbase, front overhang, rear overhang, etc.
It is possible to indicate a stop position most suitable for the type of the vehicle. Therefore, while having a wheelbase suitable for parking as before, it is possible to accommodate as many types of vehicles as possible, while minimizing the inconvenience that the suitability of parking is divided depending on the size of the front overhang. And

Further, even if the width of the front-wheel traverse conveyor 14 and the width of the rear-wheel traverse conveyor 15 are the same, various types of vehicles can be mounted by adjusting the stop position of the vehicle. Further, by sharing the front-wheel lateral feed conveyor 14 and the rear-wheel lateral feed conveyor 15, it is possible to reduce the cost and to make the load conditions of the front and rear wheel conveyors uniform. This effect can be obtained not only in the storage berth 21 but also in each of the traveling vehicle 5, the parking room 7, the storage room 11, the storage room 12, the lifting device 13, and the transfer path 16 (see FIGS. 9 to 11). By making the feed conveyor 14 and the rear-wheel lateral feed conveyor 15 common, the size becomes larger.

Furthermore, since the bogie 23 can be moved freely, it is possible to determine whether the hand brake of the vehicle 9 is activated. For example, after the vehicle 9 is stopped in a state where the vehicle 9 comes into contact with the stop 23, the actuator 24 is operated to press the front wheel 9 a with the stop 23. At this time, if the user has forgotten to apply the handbrake (or the operation state is insufficient), the vehicle 9 is pushed by the bollard 23 and moves. It is confirmed. When the handbrake is sufficiently operated, a large reaction force is detected by the load detection means 27 provided on the actuator 24, but no large reaction force is detected when the vehicle 9 moves. From the above,
It is possible to accurately determine whether or not the handbrake has been activated, and warn the driver. Therefore, according to the device of the present embodiment, forgetting to apply the handbrake of the vehicle 9 can be eliminated.

This has the following effects.
Since the hand brake is always applied to the vehicle 9, the front wheel stopper 20 (FIG. 12) of the traveling vehicle 5 becomes unnecessary. That is, since the front wheel stopper 20, which is a protrusion on the carrier of the traveling vehicle 5, can be eliminated, there is no need to limit the minimum ground clearance of the vehicle 9. Therefore, a minimum ground clearance determination device is not required. In addition, it is possible to eliminate the restriction of entry due to the minimum ground clearance, and to enter more types of vehicles.

In addition, the elimination of the front wheel stopper 20 makes it possible to freely set the width in the front-rear direction of the front-wheel traverse conveyor 14, thereby realizing the common use of the front and rear-wheel traverse conveyors 14, 15. can do. In addition, since the front and rear wheel side-feed conveyors 14 and 15 are shared, there is no restriction on the entry and exit directions of the vehicle 9, so that it is not necessary to distinguish the entry room 11 and the exit room 12. Therefore, it is necessary to change the storage room 11
It is also possible to use the storage room 12 as the storage room 11 as the storage room 12.

Next, a mechanical parking device according to a second embodiment of the present invention will be described below. The mechanical parking device according to the second embodiment includes a movable car stop 23.
And a vehicle type discriminating device suitable for the storage berth 21 including The vehicle type discriminating apparatus can be installed before the storage berth 21 or can be installed on the storage berth 21 itself. In the present embodiment, the former will be described as an example. Note that the same parts as those in the first embodiment or corresponding parts are denoted by the same reference numerals, and detailed description is omitted.

In this embodiment, a vehicle type discrimination area 29 as shown in FIG. 3 is provided in front of the entrance room 11 of the entrance / exit passage 10 shown in FIGS. This vehicle type identification area 29
Is set to be the same as the range where the vehicle 9 can be placed on the parking space of the parking room 7 or the carriage 5 (or the lifting device 13). Also, this vehicle type discrimination area
29, a virtual front / rear wheel traverse conveyor 3 is provided at a position corresponding to the installation location of the front / rear wheel traverse conveyor in the actual parking room 7 or the traveling carriage 5 (or the elevating device 13).
0 and 31 are set.

At the rear end and the front end of a virtual rear-wheel lateral feed conveyor (hereinafter simply referred to as a rear conveyor) 31, sensors for detecting passage of a vehicle are arranged. Similarly, sensors for detecting the passage of the vehicle are arranged at the rear end and the front end of a virtual front-wheel lateral feed conveyor (hereinafter, simply referred to as a front conveyor) 30. further,
Sensors for detecting the passage of the vehicle 9 are also provided at the rear end and the front end of the vehicle type determination area 29. And
The form of the vehicle passing through the vehicle type determination area 29 (the suitability of the vehicle's wheelbase, front overhang, and rear overhang for the mechanical parking device) is determined using the above-described sensors.

The procedure for judging the form of the vehicle by the vehicle type discriminating apparatus having the above configuration will be described below. The procedure for determining the form of the vehicle includes the steps shown in FIG.

(1) The entry of the vehicle into the vehicle type determination area 29 is detected, and the vehicle type determination work is started. (2) First, it is determined whether the wheelbase of the vehicle is a long wheelbase or a short wheelbase. At this time, when the relationship of (width of one of the front and rear conveyors) + (installation interval of the front and rear conveyors) <(wheel base) holds, it is determined that the wheel base is long. When the opposite relationship is established, it is determined that the wheelbase is the short wheelbase. Depending on the result at this time, the procedure for determining the front and rear overhangs described later differs. In addition, when the relationship of (the width of one of the front and rear conveyors) + (the installation interval of the front and rear conveyors) = (wheel base) is established, it is regarded as one of the long wheel base or the short wheel base,
The determination procedure described below is applied.

(3) Next, it is determined whether or not the wheelbase is suitable for storing. At this time, the relationship of (front conveyor width) + (rear conveyor width) + (front / rear conveyor installation interval)> (wheel base) or (front / rear conveyor installation interval) <(wheel base) If so, it is determined that it is suitable for storage. (4) If it is determined in step (3) that the wheelbase is suitable for storing, then it is determined whether the front and rear overhangs are suitable for storing. (5) Based on the results up to step (4), determine whether the vehicle is suitable for warehousing.

Next, an example of a specific procedure for making a judgment in each step based on the operation state of each of the above-mentioned sensors is shown in a schematic diagram of a vehicle type discrimination area shown in FIG. 3 and flowcharts shown in FIGS. This will be described below with reference to FIGS. In FIG. 3, it is assumed that the vehicle 9 advances in the vehicle type determination area 29 from right to left. The long-wheel-based vehicle 9 is indicated by a dashed line, and the short-wheel-based vehicle 9 is indicated by a dotted line.

(1.0) The vehicle 9 enters the storage area 29 (FIG. 5). (1.1) The sensor is turned on, and a control device (not shown) recognizes the entry of the vehicle 9. Then, the following vehicle type identification work is started.

(2.1) When the front wheel 9a of the vehicle passes the rear end of the rear conveyor 31, the sensor is turned on. The control device determines that the front wheel 9a is on the rear conveyor 31. (2.2) Subsequently, when the front wheel 9a passes through the front end of the front conveyor 31, the sensor is turned on. The control device is a front wheel 9a.
Has passed through the rear conveyor 31. (2.3) Next, when the sensor is turned on, it means that the front wheel 9a has passed the rear end of the front conveyor 30. At this time, since the sensor is not turned on again, the rear wheel 9b
Has not yet reached the conveyor 31. That is, (width of rear conveyor) + (installation interval of front and rear conveyors) <
(Wheel base) relationship holds. (2.4) Therefore, it can be determined that this vehicle is a long wheelbase vehicle. (2.5) If the sensor is turned on before the sensor is turned on, it means that the rear wheel 9b has passed the rear end of the rear conveyor 31. At this time, since the sensor is not turned on, the front wheel 9a has not yet reached the front conveyor 30.
That is, (width of rear conveyor) + (installation interval of front and rear conveyors)>
(Wheel base) relationship holds. (2.6) Therefore, this vehicle can be determined to be a short wheelbase vehicle.

Steps (3) and thereafter will be described separately for the case where it is determined that the vehicle is a long wheelbase vehicle and the case where it is determined that the vehicle is a short wheelbase vehicle in step (2).

In the case of a long wheel base vehicle (see FIG. 6): (3.1) When the sensor is turned on, the front wheels 9a are moved to the front conveyor.
It means that you have passed 30. At this time, since the sensor is not turned on again, the rear wheel 9b is still in the rear conveyor.
31 has not been reached. That is, since the relationship of (width of the front conveyor) + (width of the rear conveyor) + (installation interval of the front / rear conveyor) <(wheel base) is established, the front and rear wheels 9a, 9b connect the front / rear conveyors 30, 31 with each other. You will straddle it. (5.1) Therefore, at this point, it can be determined that warehousing is not possible (wheelbase is excessive).

(3.2) When the sensor is turned on, the rear wheel 9b
Is on the rear conveyor 31. At this time, the front wheel 9a is on the front conveyor 30 because the sensor is not turned on again. That is, the following relationship holds: (width of front conveyor) + (width of rear conveyor) + (installation interval of front / rear conveyor)> (wheel base). (3.3) Therefore, it can be determined that the wheelbase is suitable for storage.

(4.1) At the time of step (3.3), the vehicle 9 is located at the rearmost mounting position on the front / rear conveyors 30 and 31 (both front and rear wheels 9a and 9b, as indicated by a chain line in FIG. 3). (The most rearward position that can be placed on the conveyors 30 and 31). In this state, it is determined whether the front and rear overhangs of the vehicle are suitable for entering the warehouse. (5.2) That is, if the sensor is turned on at the rearmost mounting position, it is determined that the front overhang is excessive, and the vehicle cannot enter the parking place.

(4.2) At the time of step (3.3), if the sensor is off and the sensor is off, both the front overhang and the rear overhang are in the storage area 29. (5.3) Therefore, the vehicle is wheelbase, front,
It is determined that all the rear overhangs are within the parking area and that parking is possible.

(4.3) In step (3.3), if the sensor is off and the sensor is on, the rear overhang is protruding from the storage area 29 when the vehicle 9 is at the rearmost mounting position (FIG. 3). In the state indicated by a chain line). In this case, if the mounting position of the vehicle 9 is moved forward, there is a possibility that the rear overhang will fit in the storage area 29. Therefore, the front and rear wheels 9a and 9b are
The sensor is on (the front wheel 9a passes through the front conveyor 30) or the sensor is on (the front overhang jumps out of the storage area 29) while the vehicle is on the top of the vehicle 30 and 31 and the vehicle further advances from the rearmost mounting position. If the sensor is turned off by any of the earlier times, the rear overhang is within the storage area 29 at that point. (5.4) That is, when the condition of step (4.3) is satisfied, it can be determined that the vehicle is within the range where all of the wheelbase, front and rear overhang can be stored, and that the vehicle can be stored. (5.5) If the condition of step (4.3) is not satisfied, it is determined that the rear overhang is excessive, and the vehicle cannot be parked.

In the case of a short wheel base vehicle (see FIG. 7): (3.4) When the sensor is turned on, the rear wheel 9b is moved to the rear conveyor.
It means that it passed 31. At this time, since the sensor is not turned on again, the front wheel 9a is still in the front conveyor.
30 has not been reached. That is, since the relationship of (front and rear conveyor installation intervals)> (wheel base) is established, the front and rear wheels 9a and 9b fall between the front and rear conveyors 30 and 31. (5.6) Therefore, at this point, it can be determined that warehousing is not possible (wheelbase is too small).

(3.5) If the sensor is turned on, the front wheel 9a
Is on the front conveyor 30. At this time, the rear wheel 9b is on the rear conveyor 31 because the sensor is not turned on again. That is, the relationship of (front and rear conveyor installation intervals) <(wheel base) holds. (3.6) Therefore, it can be determined that the wheelbase is suitable for storage.

(4.4) At the time of step (3.6), the vehicle 9 is at the rearmost mounting position on the front / rear conveyors 30, 31 as shown by the dotted lines in FIG. In this state, it is determined whether the front and rear overhangs of the vehicle are suitable for entering the warehouse. (5.7) That is, if the sensor is on at the rearmost mounting position, it is determined that the front overhang is excessive, and the vehicle cannot enter the parking place.

(4.5) If the sensor is off and the sensor is off at step (3.6), both the front overhang and the rear overhang are in the storage area 29. (5.8) The vehicle therefore has a wheelbase, front,
It is determined that all the rear overhangs are within the parking area and that parking is possible.

(4.6) In step (3.6), if the sensor is off and the sensor is on, it means that the rear overhang is protruding from the storage area 29 when the vehicle 9 is at the rearmost mounting position. In this case, if the mounting position of the vehicle 9 is moved forward, there is a possibility that the rear overhang will fit in the storage area 29. Therefore, front and rear wheels 9
a, 9b are on the front and rear conveyors 30, 31 and the sensor is turned on (the rear wheel 9b passes through the rear conveyor 31) or the sensor is turned on (front) while the vehicle further advances from the rearmost mounting position. If the sensor is turned off by the earlier of the overhang jumps out of the storage area 29), the rear overhang has been stored in the storage area 29 at that time. (5.9) That is, when the condition of step (4.6) is satisfied, the vehicle can be determined to be in a parking area in which all of the wheelbase, front and rear overhangs can be stored. (5.10) If the condition of step (4.6) is not satisfied, it is determined that the rear overhang is excessive, and the vehicle cannot be parked.

Then, when it is determined that the parking is possible,
At step (5.3), (5.4), (5.8), and (5.9), the vehicle 9 is located at a position corresponding to the vehicle stop position determined to be possible to enter.
In order to stop the vehicle, the position of the wheel stop 23 of the entrance berth 21 is controlled. Then, the driver of the vehicle is guided to the storage room 11 (FIGS. 10 and 11) by some display means. If it is determined that the vehicle cannot be parked, the vehicle driver is guided to a parking space other than the mechanical parking device (a place where parking is possible regardless of the type of vehicle).

The operation and effect obtained by the second embodiment of the present invention having the above configuration are as follows. With the above-described vehicle type discriminating device, the vehicle 9 entering the storage berth 21 is subjected to wheelbase, front overhang,
It is possible to check the form of the vehicle, such as rear overhang, and to instruct a stop position suitable for the vehicle on the storage berth 21 by the bollard 23. Conventional storage berth 21
In the mechanical parking device where the stop position at the station is fixed,
Despite the fact that the wheel base is suitable for storage,
The front and rear overhangs were determined to be unsuitable for storage,
Some vehicles were unable to park. According to the present device, it is possible to store the vehicle even in such a vehicle. Therefore, it is possible to greatly increase the types of vehicles to be stored and provide a more convenient mechanical parking device. The description of the other operations and effects similar to those of the first embodiment is omitted.

Next, a mechanical parking device according to a third embodiment of the present invention will be described. In the third embodiment,
The vehicle type discriminating apparatus described in the second embodiment is connected to a berth
It is set to 21 and the berth 21 itself is also improved. Note that the same parts as those in the first and second embodiments or corresponding parts are denoted by the same reference numerals,
Detailed description is omitted.

FIG. 8 shows a storage berth 21 of a mechanical parking device according to a third embodiment of the present invention. The front-wheel lateral conveyor 32 and the rear-wheel lateral conveyor 33 are provided on a bogie 35 that can move within a pit 34 formed on the floor surface of the storage berth 21. Front / rear wheel side feed conveyor 3
2 and 33 are front and rear wheel side feed conveyors 14 and 15 shown in FIG.
In comparison with, a wider one in the front-rear direction (the left-right direction in FIG. 8) is used. The bogie 35 includes wheels 36 and is driven by an actuator 37 in the front-rear direction. Note that, depending on the position of the truck 35, a gap may be formed between the floor surface 22 of the storage berth 21 and the truck 35, and therefore, a bridge plate 38 for bridging the two is provided. As the crossover plate 38, for example, a plurality of plate members or the like which are slidably overlapped with each other and which can be expanded and contracted as a whole is used.

Then, the vehicle type discrimination area 29 is added to the berth 21.
Set. Further, the sensors for detecting the vehicle in the vehicle type determination area 29 are set to have the same positional relationship as in the second embodiment. These vehicle type determination areas 29 and sensors are fixed at fixed positions regardless of the movement of the bogie 35.

In the storage berth 21 having the above-described structure, the procedure for performing the vehicle type identification work and the subsequent storage work is as follows. (i) The bogie 35 and the bogie 23 are set at the forefront position (or a preset position). (ii) The front wheel 9a of the vehicle 9 is brought into contact with the bollard 23. Previous·
Because the wide rear conveyors 32 and 33 for the rear wheels are used, regardless of the size of the wheel base,
The rear wheels 9a and 9b are mounted on front and rear wheel lateral feed conveyors 32 and 33, respectively. (iii) In step (ii), the sensor checks whether the front overhang of the vehicle 9 is within the vehicle type determination area 29 or not. (iv) In step (ii), the front and rear wheels 9a, 9b
To see if are located between the sensors ~ and ~ respectively. (v) If the detection results in steps (iii) and (iv) indicate that the vehicle cannot enter, the trolley 35 is moved backward while the sensors
Use to search for a location where you can enter. (vi) The trolley 35 is stopped at a position where the conditions for warehousing are complete. Then, the vehicle stop 23 is retracted outside the front-wheel lateral feed conveyor 32. (vii) The front / rear-wheel lateral feed conveyors 32 and 33 are operated to deliver the vehicle.

As described above, also according to the third embodiment of the present invention, the form of the vehicle 9 is examined, and the stop position suitable for the vehicle is adjusted while the vehicle 9 is stopped on the entrance berth 21. be able to. Therefore, similarly to the second embodiment, it is possible to significantly increase the number of types of vehicles to be stored and provide a more convenient mechanical parking device as compared with the conventional mechanical parking device. Moreover, the vehicle type discrimination area
The same effect can be obtained without setting 29 at a position different from the storage berth 21. The description of the other operations and effects similar to those of the first embodiment is omitted.

[0054]

According to the present invention, the following effects are obtained. According to the mechanical parking device according to claim 1 of the present invention, when the wheel comes into contact with the vehicle stop,
The vehicle driver is informed that the vehicle has reached the stop position.
Driver can be surely grasped. Therefore, it is possible to indicate the stop position suitable for the type of the vehicle at the storage berth by the above-mentioned bollard , and has a wheelbase suitable for parking like a conventional mechanical parking device in which the stop position is fixed. On the other hand, it is possible to eliminate a problem that the suitability of parking is divided depending on the size of the front and rear overhangs, to significantly increase the number of types of vehicles to be stored, and to provide a more convenient mechanical parking device.

In addition, when the vehicle enters the vehicle type discriminating area of the vehicle type discriminating apparatus, the vehicle stop position at the entrance berth taking into account the wheel base, front overhang, and rear overhang of the vehicle using each of the sensors. Can be requested. Also, at this time, it is possible to accurately determine whether parking is appropriate or not. Therefore, even if the vehicle has a configuration that has conventionally been determined to be impossible to park, it is possible to increase the possibility of entry into the vehicle. Therefore, it becomes possible to increase the types of vehicles to be stored and provide a more convenient mechanical parking device.

Further, after the vehicle stops in a state where the vehicle is in contact with the bollard, the wheels are pressed by the bollard, whereby
You can check the operation of the handbrake to avoid forgetting to apply. Therefore, the front wheel stopper of the traveling vehicle, which is indispensable in the conventional mechanical parking device, can be eliminated. Since the front wheel stopper is a protrusion on the carrier of the traveling vehicle, it has conventionally been necessary to limit the minimum ground clearance of the vehicle to be mounted, and a minimum ground clearance discriminating device has been indispensable. According to the present invention, by eliminating the front wheel stopper, it is possible to eliminate the entry restriction due to the minimum ground clearance and to enter more types of vehicles.

According to the mechanical parking device of the second aspect of the present invention, the stop position of the vehicle (the stop position of the wheel) can be appropriately indicated by the stop for various vehicles having different wheelbases. Therefore, the front and rear wheels can be reliably mounted on the front-wheel lateral-feed conveyor and the rear-wheel lateral-feed conveyor having the same width. The cost can be reduced by sharing the front / rear wheel side-feeding conveyor. In addition, by equalizing the load conditions of the front and rear wheel conveyors, it is possible to keep the strength setting of the structure forming the apparatus as a whole at a low level, thereby promoting simplification and weight reduction of the entire apparatus. be able to. These effects can be achieved not only by the berths in the warehouse, but also by the common use of the front / rear wheel traverse conveyors in traveling trolleys, parking rooms, warehouses, etc.
It will be bigger. In addition, the common use of the front / rear wheel side-feeding conveyor eliminates the need to set restrictions on the vehicle entry and exit directions, and accordingly, it is not necessary to distinguish between the entry room and the exit room. Therefore, the storage room can be used as a storage room and the storage room can be used as a storage room as needed.

In addition, according to the mechanical parking device of the third aspect of the present invention, when the vehicle enters the storage berth,
It is possible to simultaneously determine the suitability of parking and the vehicle stop position at the entrance berth. Even when the stop position of the vehicle needs to be adjusted, the adjustment can be performed while the vehicle is stopped on the entrance berth, and the operation of adjusting the stop position at the time of entrance can be easily and reliably performed.
