For this purpose, the sensing unit 10 is installed at the front of the front wheel alignment unit 3 and at the rear of the rear wheel alignment unit 4 in order to sense the left-right alignment state of the front and rear wheels of the vehicle entering the vehicle alignment apparatus 1 do. The sensing units 10 of the front wheel and the rear wheel are configured to sense the widths of the front wheel and the rear wheel with the same structure, And the sensing unit 10 shown in FIG. 4 senses the width of the rear wheel tire.

The sensing unit 10 is arranged in the thickness direction of the wheel, i.e., the tire, in the bracket 12 arranged in the width direction at the normal entry position of the wheel, in the recessed groove 11 formed in the frame 5 A plurality of sensors 13 in the illustrated embodiment and a housing 14 which houses the sensors 13 together with the bracket 12 and which is open at the bottom, And one end is operated between a sensing position protruded above the upper surface of the frame so as to sense the wheels of the vehicle entered by the sensors 13 and a receiving position accommodated in the recess 11.

The sensors 13 of the sensing unit 10 are configured as optical sensors including a light emitting unit and a light receiving unit that emit an optical signal to the front side and receive the light reflected by the wheels of the vehicle.

The sensors 13 provided on the sensing portions 10 on both sides of the front and rear wheels are arranged in the housing 14 at the predetermined intervals in consideration of the variation range of the width of the vehicle and the allowable error range Respectively.

The housing 14 of the front and rear wheel sensing portions 10 functions as a stopper when entering the vehicle. To this end, the front wheel sensing portion 10 normally protrudes to serve as a stopper for stopping the front wheels of the incoming vehicle. At this time, the front wheel of the incoming vehicle is detected by the sensing sensor 40 provided on both sides of the front wheels When the detection is made, the rear wheel sensing portion 10 protrudes and the housing 14 functions as a stopper for the rear wheel. To this end, a lifting means is provided which allows at least one end of the housing 14 to protrude above the upper surface of the frame 5.

The front and rear wheel sensing portions 10 detect whether the wheels are left-right aligned by the sensors in a state where the housing is protruded, and the vehicle is laterally aligned by the left-right alignment device, And the vehicle is transported to the parking area with the vehicle being lifted by a transporting truck, not shown in the figure.

The lifting means includes a rotary shaft 18 rotatably supported at one end of the housing by a motor 17 and extending in the width direction of the housing 14 and an upper end fixed to both ends of the rotary shaft 18, And a link arm 19 which is rotated so as to be raised against the bottom of the recessed portion of the frame. The upper ends of the link arms 19 are fixed to the rotary shaft 18 and are rotated together with the rotary shaft 18. The lower ends of the link arms 19 are movably disposed at the bottom of the housing. Is rotatably supported by a support member (20) fixed to the bottom of the recessed portion (11) of the frame (5).

The link arm 19 is provided at the lower end of the link arm 19 so that the link arm 19 is rotated by the motor 17 in the state of being laid on the floor of the recessed groove 11 So that one end of the housing 14 is raised and lowered. At this time, the roller 22 provided at the lower end portion of the link arm 19 rolls on the bottom of the recessed portion, so that the rising operation of the link arm is smoothly performed.

A stopping member 25 is provided at the bottom of the recessed groove 11 so as to be stopped at a position where the linking arm 19 is erected so that the roller 22 provided at the lower end of the linking arm 19 contacts the stopping member 25 So that the link arm 19 is kept standing.

Thus, when the motor 17 is driven, the link arm 19 is rotated together with the rotary shaft 18 so as to be elevated upward, so that one end of the housing is lifted and detected by the sensors housed in the housing, At this time, the other end of the housing is rotated by the hinge at the support member 20.

The support member 20 is fixed to the upper surface of the frame 5 and has an upper opened hole 21 so that the free end of the support pin 24 extending to both sides at the rear end of the motor is inserted into the hole 21, Whereby the support pin 24 provided at the rear end of the motor 17 is guided to the open top of the hole 21 of the support member 20, The housing 14 provided with the motor 17 together with the motor 17 can be easily removed from the rotary shaft 18, the motor 17 and the link arm 19 together with the recess 17 of the frame 5 Maintenance work can be performed quickly.

As a result, one end of the housing 14, that is, the end of the vehicle on the wheel side is disposed to protrude above the upper surface of the vehicle alignment device 1, and the sensor 13 detects the front- A signal that detects the presence or absence of wheels is generated in a control unit not shown in the figure.

The control unit receiving signals from the sensors 13 includes a sensor 13 for detecting the presence of wheels among the sensors 13 arranged in the tire width direction of the wheels of the entry vehicle in the sensing units 10 on the left and right sides, It is determined that the left and right sides of the vehicle are equally aligned in the vehicle alignment apparatus 1. If the number of sensors 13 that detect the existence of the vehicle wheel in the left and right sensing units 10 is different It is judged that the entering vehicle has entered an unbalanced state in the vehicle alignment apparatus.

The control unit receives signals of the sensors 13 in the sensing units 10 and determines whether the alignment state of the vehicle is acceptable according to whether the number of the sensors 13 sensing the presence of the left and right wheels of the entering vehicle is the same , It is judged that the wheels on the left and right sides of the vehicle are not arranged at an equal distance in a predetermined range in accordance with the width of the vehicle according to the vehicle type, centering on the passage 2 located at the center of the frame 5 The vehicle alignment apparatus is operated to move the wheels of the front and rear wheels in the lateral direction of the vehicle so that the wheels on both sides of the passage 2 are arranged at equal distances. Then, if the number of the sensors 13 disposed in the width direction of the wheel tire and sensing the tires is the same in the left and right sensing units 10, it is determined that the vehicle is correctly aligned.

Such alignment of the vehicle in the lateral direction causes the vehicle load to act evenly to the transfer means in a lateral direction to subsequently transfer the vehicle to the parking zone in the parking installation with the transfer means lifting the vehicle.

That is, in the vehicle alignment apparatus, the front of the vehicle body is adjusted in the vehicle width direction by the rotation of the turntable 6 on which the front wheels are located, and the wheels of the rear wheels are moved in the vehicle width direction by the rotation of the rollers 20 shown in FIG. The rear side of the vehicle body is adjusted in position in the vehicle width direction so that the entrance vehicles are arranged laterally so that the wheels on both sides of the passage 2 located at the center of the frame 5 are arranged at equal distances.

The operation of the vehicle left-right alignment detecting apparatus according to the present invention will be described with reference to Figs.

A sensor 30 for detecting both front wheel wheels is provided at both sides of the frame 5 corresponding to the center of the turntable 6 so that the light irradiated by the sensor 30 on one side is transmitted to the sensor 30 on the opposite side An alarm signal is generated to determine that the vehicle has entered the control unit not shown in the drawing, and the vehicle left-right alignment detecting apparatus according to the present invention operates.

At this time, the housing 14 of the sensing unit 10 provided at the front of the front wheel alignment unit 3 is normally kept protruded upward so as to act as a stopper for preventing the front wheels of the entry vehicle from advancing further, Thereby preventing excessive entry thereof. One end of the housing 14 of the sensing portion 10 of the rear wheel alignment portion 4 on the rear wheel side of the entrance vehicle also protrudes to serve as a rear wheel side stopper and the front wheel and the housing 10 of the sensing portion 10 on the rear side The sensors 13 received in the wheels 14 sense the tire of the vehicle wheel.

The protrusions of the housing 14 of the sensing portion 10 of the front wheel alignment portion and the rear wheel alignment portion are formed so as to protrude from one side of the housing 14 opposed to the vehicle wheel as the motor 17 is operated and the link arm 19 is raised The other end of the housing 14 is rotated as a hinge shaft in the hole 21 of the support member 20 so that the support pin 24 arranged in the width direction is rotated .

Sensors 13 mounted on the bracket 12 in the housing 14 having one end raised and lowered in this manner raise the sensors for receiving the light reflected from the wheels by irradiating the light forward, The control unit senses the wheels of both the front and rear wheels to determine whether the number of the sensors 13 generating the light receiving signal is the same to judge the alignment state of the wheels of the vehicle.

That is, in the embodiment shown in Fig. 6, the circular portion shown at the top is a turntable 6 in which both front wheels of the entry vehicle are disposed, and the front wheels indicated by imaginary lines in Fig. 6 are biased to one side, Three sensors 13 transmit signals to the control unit on the right side of the wheel, four sensors 13 transmit signals to the control unit on the left side sensing unit, The control unit determines that the front wheels of the entry vehicle are not aligned at a predetermined position.

In this case, the driving means of the vehicle alignment device (not shown) operates by the control signal of the control unit, and the front side of the vehicle is displaced in the width direction as the turntable is rotated in the arrow direction. When the number of the sensors 13 receiving the reflected light from the tires of both side front wheels at the displaced position and generating the light receiving signal becomes equal, that is, when the number of the sensors 13 arranged in the width direction of both tire tires When the four sensors 13 generate a light receiving signal, it is determined that both front wheels of the vehicle are aligned at equal distances from both sides of the frame center.

In addition, in the sensing portion 10 disposed on the rear side of each of the rear wheels of the rear wheels with respect to both the rear wheels, the sensing portion 10 shown in phantom in Fig. 8 in the same manner as described above for the front wheel side sensing portions 10 In the sensor 13 arranged in the width direction of the rear wheel tire of the entry vehicle, four sensors in the left wheel side sensing unit 10 detect the wheels and three sensors 13 in the right wheel side sensing unit 10 The control unit determines that the rear wheels of the vehicle are not aligned at a predetermined position from the received light signals detected.

In this case, the control unit rotates the rollers 20 schematically shown in Fig. 1 to move the rear wheels in the width direction to the left as shown by the arrows in the figure, so that four sensors 13 Upon receiving the reflected light and sending a light receiving signal to the control unit, the control unit determines that the right and left wheels of both rear wheels are aligned (see FIG. 9).

Then, the motor 17 is driven in the reverse direction by the control unit so that the rotation shaft 18 is rotated in the opposite direction, and the link arm 19 in the erected state is laid down again so that the left and right sensing units 10 on the front wheel side, (14) is again laid down in a position accommodated in the bottom of the recessed portion.

Thus, in a state in which the front and rear wheels of the vehicle are spaced apart from each other by a uniform distance from the center and are aligned in the width direction, the vehicle is lifted with the wheels by the forwarding bogie entering the center of the frame, And is conveyed to the parking zone by the conveyance truck in a state in which it acts equally to the left and right sides with respect to the conveyance truck.

The structure in which the turntable 6 on which the both front wheels of the vehicle are arranged and the rollers 20 on which the rear wheels are disposed are arranged to align the vehicle is described in detail in the "Vehicle Arrangement for Parking Facilities" filed by the present applicant . The turntable 6 is rotated forward and backward by a drive motor provided below the turntable 6, and the rollers 20 are rotated forward and backward through a transmission gear by a motor rotating forward and backward so that the front side of the vehicle is shifted to left and right in FIG. 6 and aligned .

Thus, by allowing the entrance vehicle to be aligned at a predetermined position, the load of the vehicle, which is lifted and lowered by the conveying device that enters the passage 2 located at the center of the frame 5, It is possible to easily and accurately prevent the occurrence of various problems in the case where it is not supported.

The vehicle alignment detecting device of the present invention can be used to align the vehicle entering the parking facility with the load applied to the right and left sides evenly with respect to the conveying means.
