Description

  The present invention relates to a vehicle guidance device that guides a vehicle to accurately stop at a parking position when the vehicle is received in a mechanical parking device.

  A mechanical parking device is a facility in which a mechanical device is arranged in a building built on the ground or in a space formed in the basement to store a large number of vehicles in three dimensions, such as an elevator type, a vertical circulation type, a horizontal circulation type, Various systems such as a plane reciprocating system are used. Each of these types of mechanical parking devices has an entry / exit room for the vehicle to get into the machine device, and the vehicle runs on the pallet or cage for transporting the vehicle in the entry / exit room. I am doing so.

  The pallets, cages, etc. are of the minimum necessary size with respect to the size of the vehicle so that the space of the parking device can be utilized to the maximum, and the number of drivers of the vehicle is very limited. The driving operation is required to guide the vehicle to a certain position. In view of such circumstances, conventionally, a mirror is installed at the back of the vehicle with respect to the vehicle entry direction of the entry / exit room, and the driver visually confirms the appearance of the vehicle reflected in the mirror to assist the guidance of the vehicle. In addition, in a parking device using a pallet, a tire passing portion on the pallet is formed in a groove shape, and the lateral position where the vehicle enters is regulated so that the vehicle fits within the pallet width. (For example, refer to Patent Document 1).

On the other hand, recently, awareness of barrier-free has increased, so that wheelchair users can also use mechanical parking devices so that pallets and cages are flush with the floor in the entry / exit room, and steps are eliminated. It has been proposed that the floor surface in the loading / unloading room is configured to be flat (see, for example, Patent Document 2 and Patent Document 3).

  However, when the floor surface of the entry / exit room is configured to be flat, there is a problem that it is difficult for the driver of the vehicle to recognize the vehicle stop position. In other words, if it is a type that rides on a pallet having a groove shape as described above, the driver may operate the vehicle with the groove as a target when entering, and after the front wheel gets on the pallet, the tire tends to come off the groove. However, since the tire comes into contact with the rising surface of the groove and this feeling is transmitted to the steering wheel, the driver can easily change the direction. On the other hand, when the floor is made flat, there is no such groove, so the driver must rely on the figure of the vehicle in the mirror in front of the approach direction, and stop accurately. I feel a little anxious to guide the vehicle to the position.

  The present invention has been made in view of such circumstances, and it is possible for the driver of the vehicle to easily recognize the stop position of the vehicle in the loading / unloading room of the mechanical parking device. An object of the present invention is to provide a vehicle guidance device capable of stopping a vehicle by approaching the stop position.

In order to solve this problem, the configuration of the present invention is such that when the pallet having a flat upper surface is stopped in the loading / unloading chamber, the entrance of the mechanical parking device in which the upper surface and the floor surface of the pallet are substantially at the same level. A vehicle guidance device for guiding a vehicle to a stop position in a warehouse room, wherein a mirror provided in front of the entry / exit room in the vehicle entry direction and a floor surface of the entry / exit room along the vehicle stop position of the pallet A light-emitting body embedded in a rectangle around the periphery and a sensor for detecting the position of the vehicle in the entry / exit room, and the vehicle in the entry / exit room is brought to a normal position based on a signal from the sensor; It is determined whether or not there is a light emission state of the light emitter in a case where the vehicle in the entry / exit room is in a regular position and a case in which the vehicle in the entry / exit room is not in a regular position. It is a feature.

According to the configuration of the present invention, a light emitter is embedded in a rectangular shape on the floor surface, and the light emitter flashes or emits light to indicate the stop position of the vehicle. Therefore, when the pallet is stopped in the entry / exit room, Even in a flat mechanical parking device where the top surface and floor surface of the pallet are almost the same level, the driver can easily recognize the stop position, and particularly when it is used in a parking device in a building, the visibility is good. It becomes easy to recognize effectively.

  Hereinafter, details of the present invention will be described with reference to the drawings. FIG. 2 is a longitudinal sectional view of an elevator parking apparatus shown as an example of a mechanical parking apparatus. In the figure, a parking apparatus 11 is housed in a building 10 erected on the ground.

  A hoistway 15 passes through the central portion of the parking device 11 in the vertical direction, and parking rooms 16, 16,... Are provided on the left and right along the hoistway 15. A hoisting device 17 is installed on the upper portion of the parking device 11, and a plurality of wire ropes 18, 18,. One end of the wire ropes 18, 18,... Is fixed to the counterweight 19, and the other end is fixed to the four corners of the lift lift 20 by descending the hoistway 15. A pallet 21 and a vehicle 13 are mounted on the lift 20, and the wire ropes 18, 18,... Are driven by the hoisting device 17 to move up and down the hoistway 15 and stop at the designated parking room 16 position. Thereafter, the pallet 21 and the vehicle 13 are driven transversely, and the vehicle 13 and the pallet 21 are moved between the lifting lift 20 and the parking chamber 16 to be stored or taken out. The first floor portion of the parking device 11 serves as an entry / exit room 12 for the vehicle 13 to enter the building 10 from the outside and enter the pallet 21.

  FIG. 1 is a perspective view of the entry / exit chamber 12 as viewed from the vehicle entrance side. The central part of the floor surface 30 in the loading / unloading chamber 12 is the lowermost part of the hoistway 15, and the vehicle enters the hoisting lift 20 or the pallet 21 stopped here. Thereafter, when the driver gets out of the vehicle and exits from the loading / unloading room 12, the vehicle moves up the hoistway 15 and is transferred to a predetermined parking room 16. The upper surface of the pallet 21 is a flat plane, and when the pallet 21 is stopped in the loading / unloading chamber 12, the upper surface of the pallet 21 and the floor surface 30 are substantially at the same level so that the entire floor is on the same plane. I have to. By doing so, the floor of the entry / exit room 12 is flat with no steps, and even a driver such as a wheelchair user can easily get on and off the vehicle, and has a barrier-free structure. Can do. Around the outer periphery of the pallet 21, a plurality of light emitters 31 are embedded in the floor 30 at regular intervals, and the light emitters 31 emit light or blink in accordance with the position of the entering vehicle as will be described later. I am doing so.

  Next, a mirror 32, a guidance display device 33, a speaker 34, and a vehicle width detection sensor 35 are provided on the wall surface in the front direction of the vehicle, and a plurality of vehicle length detection sensors 36 are provided on the left and right wall surfaces. The mirror 32 reflects the image of the vehicle so that the driver can visually recognize the vehicle and perform the driving operation while confirming the position of the vehicle. The vehicle width detection sensor 35 and the vehicle length detection sensor 36 detect the position of the moving vehicle. For example, a photoelectric sensor is used to detect that the vehicle has blocked the light path, and this is detected by the vehicle position. The signal is output as a signal, and the vehicle is detected on a limit line where the vehicle can stop at a normal position. The vehicle position signals detected from these sensors are input to a controller (not shown), and the controller controls the guidance display device 33, the speaker 34, and the light emitter 31 based on the position signals. The guidance display device 33 is a device that displays characters or graphics and gives instructions to the driver, and the speaker 34 emits instructions similar to these instructions by voice.

  In the above configuration, the following operation is performed. First, when the lift 20 or the pallet 21 stops in the entry / exit chamber 12 and the vehicle can enter, the entrance door (not shown) of the entry / exit chamber 12 opens and the vehicle can enter. At this time, all the light emitters 31 on the floor 30 emit light or blink, and the vehicle driver recognizes the stop position of the vehicle by visually recognizing this. Next, on the guidance display device 33 provided on the front wall, a message such as “Please move forward” is displayed, and a similar announcement is also given from the speaker 34. At this time, the light emitters 31 arranged on the left and right of the pallet 21 blink so that the blinking sequentially flows from the near side to the back. By doing in this way, the driver can recognize that the entry into the entry / exit room 12 is possible.

  When the vehicle enters the entry / exit room 12, the vehicle width detection sensor 35 detects the position of the vehicle in the width direction. That is, when the vehicle travels in a direction shifted to the left or right with respect to the normal stop position, the vehicle width detection sensor 35 on the shifted side detects the vehicle and sends a signal to the controller. For example, if the vehicle is displaced to the right in the direction of travel, the right vehicle width detection sensor 35 on the front wall reacts to generate a signal, and the controller causes the guidance display device 33 to “go to the left” based on this signal. And a similar announcement from the speaker 34 is controlled. At this time, one row of the light emitters 31 on the right side of the pallet 21 is controlled to repeat blinking. By doing so, the driver of the vehicle can recognize well that the vehicle is displaced and the direction in which the vehicle is displaced by the light emitter 31 reflected directly or in the mirror 32, and the traveling direction of the vehicle is set to a normal position. It becomes easy to correct as follows. When the vehicle returns within the width of the normal stop position, the light emitter 31 stops blinking and enters a normal light emission state. The illuminant 31 may emit a single color, but the illuminant 31 emits red light so that the color of the light beam can be changed. In the case of a normal position, it is still effective to emit green light.

  Subsequently, when the vehicle travels in the entry / exit room 12, the vehicle length detection sensor 36a detects the front end of the vehicle, and this vehicle length detection sensor 36a detects the vehicle until the rear end of the vehicle finishes passing. to continue. When the vehicle further travels and the rear end of the vehicle has passed the position of the vehicle length detection sensor 36a, the vehicle length detection sensor 36a does not detect the vehicle. In response to this signal, the controller causes the guidance display device 33 to display “Please stop” and controls the speaker 34 to make a similar announcement. At this time, the light emitters 31 on the floor surface 30 are controlled so that all the light emitters 31 blink or are colored green, and the driver visually recognizes them with the mirror 32 and moves the vehicle. Stop. In this way, the vehicle stops at a regular position on the pallet 21.

  On the other hand, when the vehicle has passed the normal stop position, the front vehicle length detection sensor 36b detects the vehicle and issues a signal, which causes the controller to “retreat” to the guidance display device 33, etc. In addition to the display, the speaker 34 is controlled to make a similar announcement. Further, at this time, the light emitter 31 on the floor 30 is set so that the foremost horizontal row flashes or emits red light, and when the vehicle returns to the normal stop position, the light emitting body 31 is in a normal light emitting state. On the contrary, when the rear sensor of the vehicle detects the rear end portion of the vehicle, the display and announcement are “please move forward” or the like, and the light emitter 31 emits light in the last horizontal row. By doing so, the driver can easily recognize whether the vehicle is displaced forward or backward.

  Next, when the vehicle width or the vehicle length exceeds a predetermined size and a vehicle that does not fit on the pallet 21 enters, the vehicle width detection sensor 35 or the vehicle length detection sensor 36 detects the vehicle. In this case, the guidance display device 33 and the speaker 34 are displayed and announced such as “too big to enter”, and the light emitters 31 on the floor 30 have left and right columns from the back side to the entrance / exit side. Blinks so that blinking sequentially flows toward. By doing so, the driver recognizes that the vehicle is not suitable for warehousing.

  As mentioned above, although the operation | movement of each apparatus in the storage / exiting room 12 was demonstrated, the display of the guidance display apparatus 33, the announcement in the speaker 34, and the aspect which the light-emitting body 31 light-emits are not limited to the aspect demonstrated above. Any display method or light emission mode that the driver can easily recognize may be used.
