Description

[Technical field]

[0001] The present invention relates to a vehicle guidance device for a mechanical parking system. [Background technology]

[0002] In mechanical parking devices, the vehicle is generally parked in front of the entrance door of the loading / unloading room, and the user gets off the vehicle and operates the parking operation on the operation panel. There are also mechanical parking devices in which the user holds a remote control and operates the parking operation without getting off the vehicle, but in either case, the position where the user stops the vehicle in front of the entrance door is not constant, and since the vehicle is parked in front of the entrance door when the entrance door is closed, the vehicle is stopped without knowing the position of the tray located inside the loading / unloading room. In other words, the position and stopping angle of the vehicle relative to the tray are not constant each time.

[0003] In addition, recent vehicles are not only designed with a wider passenger compartment to improve passenger comfort, but also have thicker doors to improve side collision safety, which leads to an increase in vehicle width.In addition, to improve driving stability and braking performance, the treads are wider and the tires fitted to them are wider, resulting in an increase in vehicles with larger outer tire dimensions. When parking such a vehicle in a mechanical parking device, the user must take great care not to allow the outer surface of the tire to come into contact with the raised portion of the tray.

[0004] In view of this situation, Patent Document 1 describes a pair of left and right support members 23 provided on a platform 9 inside an entrance / exit 3 of a building 2, corresponding to the left and right end positions of a vehicle loading pallet 7 arranged at a vehicle transfer position. Nylon rolls 22 are rotatably attached to support shafts 24a on each support member 23 to form left and right entrance guides 21. The left and right position of a vehicle 17 is adjusted so that the vehicle 17 can pass inside the left and right entrance guides 21, and the vehicle is guided to an appropriate position for entering the vehicle loading pallet 7. In the unlikely event that the tire or wheel of the vehicle 17 comes into contact with the entrance guide 21, the contact point is made into a nylon roller 22, thereby preventing damage to the wheel or tire, and dissipating the load acting on the nylon roller 22 itself by rotating the nylon roller 22.

[0005] Furthermore, Patent Document 2 describes a tire guide that is placed at the entrance opening of a parking lot to prevent contact with erected members. The tire guide is fixedly placed on the left and right sides of the lower part of the opening, and has inclined surfaces that extend to the left and right from the ground surface upward, and when an incoming vehicle gets too close to the left or right of the entrance, the tires of the vehicle slide along the inclined surfaces to guide the vehicle to the center of the opening. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2008-150905 A [Patent Document 2] JP 2013-096222 A Summary of the Invention [Problem to be solved by the invention]

[0007] The storage guide described in Patent Document 1 adjusts the left-right position of the vehicle so that it can pass inside the left and right storage guides, thereby guiding it to an appropriate position for entering onto the vehicle loading pallet. However, when the tires or wheels of the vehicle come into contact with the storage guide, the nylon roll is rotatably attached to the support shaft on each support member, and the nylon roll is damaged by the physical impact of the tire or wheel, requiring the nylon roll to be replaced within a short period of time. Furthermore, if a large force is applied to the support shaft on which the nylon roll is rotatably attached and damaged, the support shaft must be replaced as well.

[0008] In addition, the tire guiding member described in Patent Document 2 has an inclined surface that extends from the ground surface upward to the left and right, and when a vehicle entering the vehicle gets too close to the left or right of the entrance, the tires of the vehicle slide on the inclined surface, but the tires may ride on the inclined surface and be unable to slide. Also, in the case of a vehicle that is wide and has a large distance between the left and right tires (tread), the left and right tires ride on the tire guiding member, and the tires cannot slide left and right.

[0009] In order to eliminate the inconveniences of the above-mentioned prior art, the present invention aims to provide a vehicle guide device for a mechanical parking device that prevents tires and wheels from coming into contact with the tray by detecting the outer-to-outer tire dimensions in advance in relation to the entire width of the road on both sides of the tray before the vehicle enters the loading / unloading room and moving the vehicle itself left and right. [Means for solving the problem]

[0010] A vehicle guidance device for a mechanical parking device according to a first embodiment is a mechanical parking device comprising an entry / exit room having an entrance / exit door that allows vehicles to enter and exit a tray, and a driveway continuing to the front of the entrance / exit door of the entry / exit room, in which the tray has a shape with raised portions on both the left and right sides of the loading surface on which the vehicle is placed, and the device has a tire outer surface detection sensor having an optical axis that emits and receives light in close proximity in a direction along the side of the raised portion, and a vehicle position adjustment device that is provided on the driveway and, when the tire outer surface detection sensor detects the outer surface of the tire of the vehicle entering the parking lot, moves the vehicle in a direction in which the outer surface of the tire is not detected.

[0011] The second aspect of the vehicle guidance device for a mechanical parking device is the vehicle guidance device for a mechanical parking device of the first aspect, wherein one of the tire outer surface detection sensors is installed at the rear side of the tray in the loading / unloading room in the vehicle entry direction, and the other sensor is installed at the front side of the vehicle position adjustment device on the rear wheel side of the road in the vehicle entry direction.

[0012] The vehicle guidance device for a mechanical parking device of the third aspect is the vehicle guidance device for a mechanical parking device of the first or second aspect, in which the tire outer surface detection sensor and the front wheel position detection sensor are installed in a state where a portion of the sensor is buried in the floor of the roadway.

[0013] In the vehicle guidance device of a mechanical parking device of the fourth aspect, in the vehicle guidance device of a mechanical parking device of the first or second aspect, when the entrance / exit door begins to open and the tire outer surface detection sensor detects the tire outer surface, the entrance / exit door is temporarily stopped and an entrance guide light installed at or near the entrance / exit door informs the vehicle user to adjust the position of the vehicle, and when the vehicle position adjustment device has completed adjusting the position of the vehicle, the opening operation of the entrance / exit door is resumed.

[0014] The vehicle guidance device for a mechanical parking device of the fifth aspect is the vehicle guidance device for a mechanical parking device of the first or second aspect, in which the vehicle position adjustment devices are installed separately for the front wheels and the rear wheels, and adjust the position of the vehicle individually in the left-right direction, and are equipped with a front wheel position detection sensor that corresponds to the vehicle position adjustment device for the front wheels and emits and receives an optical axis in a direction intersecting the optical axis of the tire outer surface detection sensor to detect that the front wheels of the vehicle are stopped within the range of the vehicle position adjustment device for the front wheels.

[0015] The vehicle guidance device of a mechanical parking device in the sixth aspect is the vehicle guidance device of a mechanical parking device in the first or second aspect, in which the vehicle position adjustment device is a plate-shaped vehicle position adjustment plate that moves laterally in a direction perpendicular to the vehicle's entrance direction.

[0016] The seventh aspect of the vehicle guidance device for a mechanical parking device is the vehicle guidance device for a mechanical parking device of the first or second aspect, wherein the vehicle position adjustment device is a vehicle position adjustment conveyor that rotates endlessly in a direction perpendicular to the vehicle's entrance direction. Effect of the Invention

[0017] According to the vehicle guiding device of the mechanical parking device of the first aspect, it is possible to prevent the tires or wheels from coming into contact with the raised portion of the tray when the vehicle enters the tray.

[0018] The vehicle guidance device of the mechanical parking device of the second aspect is capable of detecting the outer surfaces of the tires of the front and rear wheels of a vehicle entering the parking lot, compared to a tire outer surface detection sensor that corresponds only to the front wheel side or only to the rear wheel side, and is able to guide the vehicle in an almost straight direction relative to the tray.

[0019] According to the vehicle guidance device of the mechanical parking device of the third aspect, the sensor can function without hindrance even when the vehicle tires run over the sensor, compared to a sensor that is installed so as to rise up into the roadway.

[0020] According to the vehicle guidance device of the mechanical parking device of the fourth aspect, the vehicle position can be adjusted while the vehicle is stopped, compared to a device that notifies the user to adjust the vehicle's position after the entrance / exit door is fully opened.

[0021] According to the vehicle guidance device of the mechanical parking device of the fifth aspect, it is possible to confirm that the position of the front wheels of the vehicle is stopped on the vehicle position adjustment device, compared to a device that does not detect the stopping position of the front wheels.

[0022] According to the vehicle guidance device for a mechanical parking device according to the sixth aspect, the structure is simpler than that of a conveyor type, and an increase in costs can be suppressed.

[0023] According to the vehicle guidance device of the mechanical parking device of the seventh aspect, fine adjustment of the lateral position of the vehicle becomes easier than with a plate type device. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] An example of a vehicle guide device for a mechanical parking device according to the present embodiment will be described with reference to the drawings. Note that although the tires will be described as front wheels or rear wheels when the front wheels and rear wheels are described separately, the front wheels and rear wheels will be described collectively as tires.

[0026] [First embodiment] <Overall configuration of the area surrounding the entrance and exit room of a mechanical parking device> Fig. 1 shows an example of the periphery of the loading / unloading room of the mechanical parking device of the present invention. As shown in Fig. 1, the periphery of the loading / unloading room of the mechanical parking device 1 includes the loading / unloading room 2 and a front open space 10, and the front open space 10 is provided with vehicle position adjustment devices 20 for the front and rear wheels of the vehicle 50.

[0027] [Storage room] As shown in FIG. 1, the loading / unloading room 2 is formed in a part of the building 1A, and in this embodiment, the building 1A is composed of a framework. The loading / unloading room 2 is provided with a floor 4 in which an opening 5 is formed. The upper surface of the floor 4 is at the same level as the boarding level L where the vehicle 50 boards the tray 40. In addition, an entrance door 6 is provided in a part of the wall of the loading / unloading room 2 in the direction in which the vehicle 50 advances and retreats, and an operation panel 7 for users to operate the loading and unloading is installed beside the entrance door 6. In addition, at the back side in the loading direction of the vehicle 50, there are provided an entrance guide light 8 that guides the user of the vehicle 50 to enter the parking lot, and a mirror for the user to check the position of the vehicle when the vehicle 50 enters the parking lot. In addition, although not shown, in this embodiment, a storage room that stores the tray via a lift is provided below the loading / unloading room 2. In addition, at the back side of the loading / unloading room 2 in the tray 40, a pair of light-emitting side sensors of the tire outer surface detection sensor 30 described later are provided.

[0028] [Roadway] In this embodiment, the roadway 10 is formed by a skeleton, and a floor 11 of the skeleton is at the same level as the floor of the loading / unloading room 2. On the floor 11 of the roadway 10, vehicle position adjustment devices 20 (described later) are installed separately on the front wheel side and the rear wheel side, and a sensor on the light receiving side of a tire outer surface detection sensor 30 and a pair of front and rear front wheel position detection sensors 32 are also provided.

[0029] 〔tray〕 2, the tray 40 includes a pair of left and right support surfaces 42 on which the tires of the vehicle 50 run and are placed, raised portions 44 that rise continuously from the left and right outer sides of each support surface 42, and side surfaces 46 of the raised portions 44 facing the inner surface of the tray 40. The support surfaces 42, raised portions 44, and side surfaces 46 of the tray 40 are each formed of a steel plate, and generally, a checkered plate or flat steel is used. Note that the optical axis 38, which will be described later, is located close to the side surfaces 46 and is projected along the side surfaces 46.

[0030] <Main components> Here, the configuration of the main part will be described with reference to FIG. 1 to FIG. [Vehicle position adjustment device] As shown in Fig. 1, a vehicle position adjustment device 20 for front wheels is provided on the floor 11 of the roadway 10 on the side close to the entrance door 6 of the loading / unloading room 2, and a vehicle position adjustment device 20 for rear wheels is provided on the opposite side of the entrance door 6 from the vehicle position adjustment device 20 for front wheels. Although the vehicle position adjustment devices 20 are divided into those for the front wheels and those for the rear wheels, the structure is the same, so an explanation will be given based on the vehicle position adjustment device for front wheels shown in Fig. 3.

[0031] [Vehicle position adjustment plate] The vehicle position adjustment device 20 comprises a vehicle position adjustment plate 22 installed horizontally in a pit 12 formed on the floor 11 of the roadway 10 so as to be movable in a direction intersecting the entrance direction of the vehicle 50, and rails 26 for moving the vehicle position adjustment plate 22 provided on the pit bottom 14, and rollers 24 provided on the underside of the vehicle position adjustment plate 22 are placed movably on the rails 26. The underside of the vehicle position adjustment plate 22 is connected via a bracket 23 to a drive unit 28 fixed to the pit bottom 14, and the vehicle position adjustment plate 22 can be moved in the left-right direction of the vehicle 50 by driving the drive unit 28.

[0032] A deck 18 is fixed to a pit edge 16, which is the upper edge of the pit 12, so as to cover the end of the vehicle positioning plate 22. The deck 18 has a size sufficient to allow the amount of movement associated with left and right movement of the vehicle positioning plate 22, and is designed so that the floor 11 does not open even if the vehicle positioning plate 22 moves.

[0033] As described above, the vehicle position adjustment plate 22 for the front wheels is installed on the side closer to the entrance door 6, and the vehicle position adjustment plate 22 for the rear wheels is installed at a distance from the vehicle position adjustment plate 22 for the front wheels on the side farther from the entrance door 6 (see FIG. 1). Also, the vehicle position adjustment plate 22 for the rear wheels has a larger dimension in the entrance direction of the vehicle 50 than the vehicle position adjustment plate 22 for the front wheels in order to accommodate the wheelbases of the vehicles 50 having various lengths.

[0034] [Tire outer surface detection sensor] As shown in Fig. 1, the tire outer surface detection sensor 30 has a light-emitting sensor installed at the rear side of the tray 40 in the loading / unloading room 2, and a light-receiving sensor installed on the side of the vehicle position adjustment plate 22 for the rear wheels away from the entrance / exit door 6, i.e., on the rear side of the vehicle 50. As shown in Fig. 2, the optical axis 38 of the tire outer surface detection sensor 30 emits and receives light in close proximity to a direction along a side surface 46 of a rising portion 44 of the tray 40. A photoelectric tube, a laser sensor, or the like is used as the sensor.

[0035] [Front wheel position detection sensor] 1 and 3, the front wheel position detection sensor 32 is provided on the front wheel vehicle position adjustment plate 22 so that an optical axis 38 emits and receives light at positions corresponding to the front and rear of the front wheels in a direction intersecting the entrance direction of the vehicle 50. This front wheel position detection sensor 32 detects that the front wheels of the vehicle 50 are stopped on the front wheel vehicle position adjustment plate 22. The front wheel position detection sensor 32 also uses a photoelectric tube, a laser sensor, or the like as a sensor.

[0036] [Configuration and installation of tire outer surface detection sensor and front wheel position detection sensor] In this embodiment, the tire outer surface detection sensor 30 and the front wheel position detection sensor 32 have the same structure. As shown in Fig. 6 to Fig. 8, the tire outer surface detection sensor 30 and the front wheel position detection sensor 32 are substantially rectangular in plan view, and have an embedded part 35 embedded in the floor 11, and a trapezoidal shape formed from the embedded part 35, with a hole 34 through which an optical axis 38 of the sensor passes drilled in one surface of the trapezoidal protruding part 33. The sensor main body is provided inside the protruding part 33 exposed above the floor 11, and the embedded part 35 and the protruding part 33, and the wiring of the signal system of the sensor (not shown) is connected to a control panel of the mechanical parking device 1 (not shown).

[0037] 7 and 8, the protruding portions 33 of the tire outer surface detection sensor 30 and the front wheel position detection sensor 32 are installed in a form in which the embedding portions 35 are embedded and fixed in the floor 11, and only the protruding portions 33 are exposed on the floor 11. The tire outer surface detection sensor 30 and the front wheel position detection sensor 32 are shaped so as not to damage the tires even if the tires of the vehicle 50 run over them.

[0038] [Function of main parts] Here, the operation of the main parts will be described with reference to FIGS.

[0039] [Vehicle location determination] 1, a vehicle 50 is stopped with its tires positioned on the vehicle position adjustment plate 22 of the vehicle position adjustment device 20 for front and rear wheels installed on a roadway 10. The front wheel position detection sensor 32 provided corresponding to the vehicle position adjustment plate 22 for the front wheels has the optical axis 38 for projecting and receiving light both in front and behind the tire in a receiving state, i.e., in an ON state, and thus determines that the front wheels are stopped within the range of the vehicle position adjustment plate 22 for the front wheels.

[0040] [Vehicle position adjustment] As shown in Figure 4, the tire outer surface 54 of the tire 52 of the vehicle 50 is positioned in the width direction of the vehicle position adjustment plate 22 between the two optical axes 38 (see Figure 1) of a pair of left and right tire outer surface detection sensors 20. When the vehicle 50 stops in this state, the vehicle position adjustment plate 22 does not move, and when an empty tray 40 has landed in the loading / unloading room 2 and is ready to be loaded, the entrance / exit door 6 opens, and the user can load the vehicle 50 onto the tray 40.

[0041] When the entrance door 6 of the loading / unloading room 2 opens, the tire position detection sensor 20 is energized to emit and receive light along the optical axis 38, and when the entrance door 6 closes, the power supply is cut off to stop the emission and reception of light along the optical axis 38. In other words, when the entrance door 6 of the loading / unloading room 2 begins to open, the tire outer surface detection sensor 30 is energized and the optical axis 38 emits and receives light.

[0042] On the other hand, as shown in Fig. 5, when the optical axis 38 detects the tire outer surface 54 of the tire 52 on the left side of the vehicle 50, it is determined that the left-right position of the vehicle 50 is shifted to the left with respect to the tray 40. In this case, the vehicle position adjustment plate 22 moves in the direction of arrow A. That is, the vehicle 50 is moved to the right until it is moved to a position where the optical axis 38 does not detect the left tire outer surface 54. This state is as shown in Fig. 4.

[0043] As a result, the left and right tire outer surfaces 54 of the vehicle 50 are positioned inside the side surfaces 46 of the left and right rising portions 44 of the tray 40, and even if a user places the vehicle 50 in this state on the tray 40, the left and right tire outer surfaces 54 do not come into contact with the side surfaces 46 of the rising portions 44 of the tray 40.

[0044] During the adjustment of the left-right position of the vehicle 50, the entrance guide light 8 displays "Stop," "Vehicle position being adjusted," etc., and also issues an audio notification to encourage the user to keep the vehicle 50 stopped. This display and audio notification are also performed from a display panel and a speaker provided on the operation panel 7. The entrance guide light 8 is installed in the entrance / exit room 2, but as shown in FIG. 1, a thin LED display panel can be provided on one surface of the entrance / exit door 6, or the entrance / exit door 6 can be built in to display multiple warnings to the user. In this case, the LED display panel may be provided on the entrance / exit door 6, or on a wall above the three-sided frame of the entrance / exit door 6, or on the left and right of the three-sided frame, or on either one of them.

[0045] In addition, when adjusting the position of the vehicle 50 by the tire outer surface detection sensor 30, the entrance / exit door 6 begins to open, and power is applied to the sensor to begin emitting and receiving light from the optical axis 38. However, when the entrance / exit door 6 begins to open and the tire outer surface detection sensor 30 detects the tire outer surface 54, the entrance / exit door 6 is temporarily stopped, and the entrance / exit door 6 or the entrance / exit door 8 installed in its vicinity informs the user riding in the vehicle 50 that the position of the vehicle 50 should be adjusted. The opening operation of the entrance / exit door 6 may be controlled to be resumed when the position adjustment of the vehicle 50 by the vehicle position adjustment device 20 is completed.

[0046] <Modification> Here, the modified example will be described with reference to Figures 9 to 11. In the modified example, new components are given new reference numerals, and components that are the same as those in the above embodiment are given the same reference numerals.

[0047] 9, the modified example is configured by replacing the vehicle position adjustment device 120 with a vehicle position adjustment conveyor 122 instead of the vehicle position adjustment plate 22. To facilitate maintenance, the drive unit 126 is located outside the vehicle position adjustment conveyor and is covered by a cover bolted to the floor 11. The tire outer surface detection sensor 30 and the front wheel position detection sensor 32 are the same as in the above embodiment, so a description thereof will be omitted.

[0048] [Vehicle position adjustment conveyor] As shown in Fig. 10, the vehicle position adjustment conveyor 122 is a conveyor that rotates in a direction intersecting the entrance direction of the vehicle 50 in the pit 12. The vehicle position adjustment conveyor 122 is hung on rotating shafts 124 at the left and right ends, and a number of plate-like bodies are attached to a cord-like body to make it rotatable. In this modified example, one of the rotating shafts 124 is connected to a drive unit 126.

[0049] 10 shows a state in which the tire outer surface 54 on the left side of the vehicle 50 is detected by the optical axis 38 (see FIG. 1) of the tire outer surface detection sensor 30. From this state, the vehicle position adjustment conveyor 122 rotates rightward to move the vehicle 50 in the direction of arrow A, so that the tire outer surface 54 of the tire 52 on the left side of the vehicle 50 moves in a direction away from the optical axis 38 of the tire outer surface detection sensor 30.

[0050] 11 shows a state in which the outer tire surface 54 on the left side of the vehicle 50 is moved away from the left optical axis 38 (see FIG. 1) by the right rotation of the vehicle position adjustment conveyor 122 and to a position where it does not contact the side surfaces 46 of the left and right raised portions 44 of the tray 40. In this manner, in this modified example, by replacing the vehicle position adjustment plate 22 with the vehicle position adjustment conveyor 122, the left and right position adjustment of the vehicle 50 can be finer than with the vehicle position adjustment plate 22.

[0051] In this way, the vehicle guidance device for the mechanical parking device of the present invention is a mechanical parking device 1 comprising an entry / exit room 2 having an entrance / exit door 6 that allows a vehicle 50 to enter and exit the tray 40, and a vehicle path (front open space) 10 that continues to the front of the entrance / exit door 6 of the entry / exit room 2, in which the tray 40 is shaped with raised portions 44 on both the left and right sides of the loading surface 42 on which the vehicle 50 is placed, and the tray 40 has a tire outer surface detection sensor 30 having an optical axis that emits and receives light in close proximity in a direction along the side surface 46 of the raised portion 44, and a vehicle position adjustment device 20 that is provided on the vehicle path 10 and, when the tire outer surface detection sensor 30 detects the outer surface of the tire of the vehicle 50 entering the parking lot, moves the vehicle 50 in a direction where the outer surface of the tire is not detected.

[0052] This makes it possible to prevent the tires and wheels from coming into contact with the raised portion 44 of the tray 40 when the vehicle 50 enters the tray 40.

[0053] In addition, one of the tire outer surface detection sensors 30 is installed at the rear side of the tray 40 in the loading / unloading room 2 in the vehicle entry direction, and the other sensor is installed at the front side of the vehicle position adjustment device 20 on the rear wheel side of the roadway 10 in the vehicle entry direction.

[0054] This makes it possible to detect the tire outer surfaces of the front and rear wheels of the entering vehicle 50, compared to when the tire outer surface detection sensor 30 corresponds only to the front wheel side or only to the rear wheel side, and allows the vehicle 50 to be guided in an almost straight direction relative to the tray 40.

[0055] Moreover, the tire outer surface detection sensor 30 and the front wheel position detection sensor 32 are installed on the roadway 10 with a part of each sensor buried in the floor 11 of the roadway 10 .

[0056] This allows the sensor to function without hindrance even when the tires of the vehicle 50 run over the sensor, as compared to a sensor that is installed so as to rise up from the roadway 10.

[0057] In addition, when the entrance / exit door 6 begins to open and the tire outer surface detection sensor 30 detects the tire outer surface 54, the entrance / exit door 6 is temporarily stopped, and the entrance guide light 8 installed at or near the entrance / exit door 6 informs the user in the vehicle 50 to adjust the position of the vehicle 50, and when the vehicle position adjustment device 20 has completed adjusting the position of the vehicle 50, the opening operation of the entrance / exit door 6 is resumed.

[0058] This allows the position adjustment of the vehicle 50 to be performed while the vehicle 50 is stopped, as compared with a system in which the user is notified of the position adjustment of the vehicle 50 after the entrance door 6 is fully opened.

[0059] In addition, the vehicle position adjustment devices 20 are installed separately for the front wheels and rear wheels, and adjust the position of the vehicle 50 individually in the left-right direction. In addition, corresponding to the vehicle position adjustment device 20 for the front wheels, a front wheel position detection sensor 32 is provided which emits and receives an optical axis in a direction intersecting the optical axis of the tire outer surface detection sensor 30 to detect that the front wheels of the vehicle 50 are stopped within the range of the vehicle position adjustment device 20 for the front wheels.

[0060] This makes it possible to confirm that the position of the front wheels of the vehicle 50 is stopped on the vehicle position adjustment device 20, as compared to a system that does not detect the stopping position of the front wheels.

[0061] The vehicle position adjustment device 20 is a plate-shaped vehicle position adjustment plate 22 that moves laterally in a direction perpendicular to the entrance direction of the vehicle 50 .

[0062] This simplifies the structure compared to the conveyor type, and reduces the cost.

[0063] The vehicle position adjustment device 20 is a vehicle position adjustment conveyor 122 that rotates endlessly in a direction perpendicular to the entrance direction of the vehicle 50 .

[0064] This makes it easier to fine-tune the lateral position of the vehicle compared to a plate-type device.
