The placement surface 41a is configured to be positioned substantially on the same plane as the extension surface of the placement region 7, for example. Thereby, the level | step difference between the mounting surface of the trolley | bogie main body 41 and the extension surface of the mounting area | region 7 is eliminated, and the fork main body 32 mentioned later can be extended and shortened smoothly. The cart body 41 includes a second fork guide (not shown) that guides a second fork 47 described later in the second direction D2.

  The cart drive mechanism 42 moves the transport cart 31 in the first direction D1. Thereby, the cart drive mechanism 42 conveys the mounted passenger car V in the first direction D1. In the form illustrated in the present embodiment, the cart drive mechanism 42 includes a wheel 43 having a rotation shaft extending in the second direction D2 and a drive motor 44 that rotates the wheel 43. The wheel 43 is attached to the transport carriage 31 via a bearing (not shown). The wheel 43 is configured to roll on the end edge of the storage space 5.

  The fork main body 32 includes a first fork 46 and a second fork 47, and is configured to expand and contract in the second direction D2. The second fork 47 is attached to the transport carriage 31 so as to be able to move forward and backward relative to the transport carriage 31 in the second direction D2. The first fork 46 is attached to the second fork 47 in the second direction D2. The second fork 47 is attached to the second fork 47 so as to be able to move forward and backward. Hereinafter, an example of a detailed configuration of the fork main body 32 will be described, but the configuration is not limited to this configuration.

  The second fork 47 is a columnar body that is located at a substantially central portion in the first direction D1 of the carriage main body 41 and extends in the second direction D2. The second fork 47 is guided by the second fork guide portion of the carriage main body 41 described above, and is configured to be able to move forward and backward relative to the carriage main body 41 in the second direction D2. One end 47a and the other end 47b of the second fork 47 are provided with wheels 45 configured to roll on the mounting surface 41a of the carriage main body 41 in the second direction D2, and the second fork 47 is supported by wheels 45.

  The first fork 46 is attached to the second fork 47 so as to be movable back and forth in the second direction D2.

  The first fork 46 is a columnar body that is positioned substantially at the center of the carriage body 41 in the first direction D1 and extends in the second direction D2. That is, the first fork 46 extends in the same direction as the second fork 47. As shown in FIG. 4, the first fork 46 includes a pair of opposing side walls 46c and an upper wall 46d that connects the upper ends of the pair of side walls 46c. The second fork 47 is disposed in the space S surrounded by the pair of side walls 46 c and the upper wall 46 d of the first fork 46, and is covered with the first fork 46. Further, the cable 38, the first chain 55, the second chain 56, and the third chain 57 for driving each driving device are also arranged in the space S. That is, the first fork 46 protects the second fork 47, the cable 38, the first chain 55, the second chain 56, the third chain 57, and the like located in the space S. Therefore, it is not necessary to separately provide a protective cover for protecting these devices, and the transporter 3 can be configured compactly.

  The first fork 46 is guided by the second fork 47 and is configured to be movable back and forth in the second direction D2 with respect to the second fork 47. That is, for example, the guide rollers 50 having the rotation shaft extending in the vertical direction are provided on both side surfaces of the second fork 47, respectively. The guide roller 50 is slidably in contact with the inner surface of the side wall 46c. Therefore, the fork main body 32 has a so-called telescopic structure.

  A wheel 59 is also provided on the other end 46b of the first fork 46, and is configured to roll on the mounting surface 41a of the carriage body in the second direction D2.

  As shown in FIGS. 2 and 3, one end 46 a of the first fork 46 is supported by a first base 71 of a first holding part 61 described later. That is, the first fork 46 is provided so as to protrude outward from the side wall 46c, for example, and the first fork 46 of the first holding part 61 is interposed via a pair of pins 48 whose axis extends in a direction perpendicular to the second direction D2. 1 base 71 is connected. As a result, when the first fork 46 moves back and forth in the second direction D2, the first holding portion 61 also moves back and forth in the second direction D2 in conjunction with the operation of the first fork 46. The first fork 46 is configured to rotate relative to the first holding portion 61 around the axis of the pair of pins 48. Accordingly, when the ground contact surface of the wheel 59 of the first fork 46 and the ground contact surface of each wheel 78 and / or the auxiliary wheel 77 of the first holding portion 61 are not located in the same plane, the first holding portion 61 is a pair. The wheel 48 and / or the auxiliary wheel 77 of the first holding part 61 are maintained in a grounded state by rotating around the axis of the pin 48. As a result, an excessive load is applied to the connecting portion between the first holding portion 61 and the first fork 46, and this portion can be prevented from being damaged. The first fork 46 is supported by the wheels 59 and the first holding portion 61 of the first fork 46, and is configured such that the bottom surface is separated from the placement surface 41a.

The portion on the other end 55b side of the portion wound on 52 is wound on the first sprocket 51, and the other end 55b is attached on the other end 47b side in the second direction D2 of the second fork 47. ing.

  The second chain 56 has one end 56 a attached to the one end 41 b side in the second direction D 2 of the carriage body 41 and the other end 56 b attached to the one end 46 a side in the second direction D 2 of the first fork 46. The intermediate portion is wound around the fourth sprocket 54.

  The third chain 57 has one end 57 a attached to the other end 41 c side in the second direction D 2 of the carriage body 41 and the other end 57 b attached to the other end 46 b side in the second direction D 2 of the first fork 46. The intermediate portion is wound around the third sprocket 53.

  The fork drive unit 58 moves the first chain 55 in the extending direction by rotational driving of the output shaft. Hereinafter, an example of a detailed configuration of the fork drive unit 58 will be described, but the configuration is not limited to this configuration.

  The 1st sprocket 51, the 2nd sprocket 52, the 3rd sprocket 53, and the 4th sprocket 54 are comprised by the well-known sprocket. However, the present invention is not limited to this, and instead of this, for example, a roller may be used.

  The first sprocket 51 is attached to an end of the carriage main body 41 on the side where the first storage space 5A is located, and is configured to rotate around an axis that is orthogonal to the second direction D2 and extends in the horizontal direction. ing.

  The second sprocket 52 is attached to the end of the carriage main body 41 on the side where the second storage space 5B is located, and is configured to rotate around an axis that is orthogonal to the second direction D2 and extends in the horizontal direction. ing.

  The third sprocket 53 is attached to the end of the second fork 47 on the side where the first storage space 5A is located, and is configured to rotate around an axis that is orthogonal to the second direction D2 and extends in the horizontal direction. Has been.

  The fourth sprocket 54 is attached to the end of the second fork 47 on the side where the second storage space 5B is located, and is configured to rotate around an axis that is orthogonal to the second direction D2 and extends in the horizontal direction. Has been.

  The first chain 55, the second chain 56, and the third chain 57 are configured by well-known roller chains. However, the present invention is not limited to this, and instead of this, for example, a belt may be used.

  The first chain 55 has one end 55 a fixed to the one end 47 a side in the second direction D 2 of the second fork 47. The other end 55b is fixed to the other end 47b side in the second direction D2 of the second fork 47. The second sprocket 52 and the first sprocket 51 are engaged with each other. The first chain 55 is “touched” by the carriage main body 41 and the second fork 47 when viewed from the direction orthogonal to the second direction D2.

  Further, one end 56 a of the second chain 56 is fixed to the one end 41 b side in the second direction D 2 of the carriage body 41, and the other end 56 b is the one end 46 a side in the second direction D 2 of the first fork 46. The intermediate portion meshes with the fourth sprocket 54.

  The third chain 57 has one end 57 a fixed to the other end 41 c side in the second direction D 2 of the carriage body 41 and the other end 57 b on the other end 46 b side in the second direction D 2 of the first fork 46. The intermediate portion meshes with the third sprocket 53.

  8 and 9 are diagrams illustrating an example of the operation of the fork drive unit 58. FIG.

  The fork drive unit 58 is constituted by a motor, for example, and is attached to the carriage main body 41. A drive sprocket 49 that meshes with the first chain 55 via a speed reducer is attached to the output shaft of the fork drive unit 58. Therefore, the drive sprocket 49 is rotated by the drive of the fork drive unit 58, and the first chain 55 is moved in the extending direction.

  The fork drive unit 58 includes a first brake 58a (see FIG. 7). By operating the first brake 58a, the rotation of the output shaft of the fork drive unit 58 is restricted. By releasing one brake 58a, the output shaft of the fork drive unit 58 is allowed to rotate. Therefore, by operating the first brake 58a, the first holding portion 61 with respect to the carriage main body 41 via the first chain 55, the second chain 56, the third chain 57, the first fork 46, and the second fork 47. Movement is regulated. In addition, by releasing the first brake 58a, the driving force or the external force of the fork drive unit 58 causes the first chain 55, the second chain 56, the third chain 57, the first fork 46, and the second fork 47 to pass through. Thus, the first holding part 61 can be moved in the second direction D2.

  Therefore, as shown in FIG. 8, when the fork drive unit 58 rotates the drive sprocket 49 in the first rotation direction R1, the other end 55b of the first chain 55 moves in the direction toward the first storage space 5A. The second fork 47 is pulled by the first chain 55 and moves in the direction toward the first storage space 5A. When the second fork 47 moves and the third sprocket 53 attached to the second fork 47 moves in the direction toward the first storage space 5A, the third chain 57 meshing with the third sprocket 53 is obtained. Tries to pull the cart main body 41 to which one end 57a is attached and the first fork 46 to which the other end 57b is attached in the second direction D2. However, since the carriage main body 41 is configured not to move in the second direction D2, only the first fork 46 has the same distance as the second fork 47 in the same direction as the movement distance of the second fork 47. Moving. In this way, the fork drive unit 58 can extend the fork main body 32 toward the first storage space 5A.

  Similarly, the fork drive unit 58 rotates the drive sprocket 49 in the first rotation direction R1, thereby shortening the fork main body 32 extended toward the second storage space 5B toward the first storage space 5A. it can.

  As shown in FIG. 9, when the fork drive unit 58 rotates the drive sprocket 49 in the second rotation direction R2, one end 55a of the first chain 55 moves in the direction toward the second storage space 5B, and The two forks 47 are pulled by the first chain 55 and move in the direction toward the second storage space 5B. When the second fork 47 moves and the fourth sprocket 54 attached to the second fork 47 moves in the direction toward the second storage space 5B, the second chain 56 meshing with the fourth sprocket 54 is obtained. Tries to pull the cart body 41 to which the one end 56a is attached and the first fork 46 to which the other end 56b is attached in the second direction D2. However, since the carriage main body 41 is configured not to move in the second direction D2, only the first fork 46 has the same distance as the second fork 47 in the same direction as the movement distance of the second fork 47. Moving. In this manner, the fork drive unit 58 can extend the fork main body 32 toward the second storage space 5B.

  Similarly, the fork main body 32 extended toward the first storage space 5A can be shortened toward the second storage space 5B by the fork drive unit 58 rotating the drive sprocket 49 in the second rotation direction R2. it can.

  Thus, the fork drive mechanism 33 drives the fork main body 32 to move the fork main body 32 in the second direction D2, that is, in the direction from the first storage space 5A to the second storage space 5B and from the second storage space 5B. This is a mechanism that expands and contracts in the direction toward the first storage space 5A.

  The second fork 47 is between the position where the other end 55b of the first chain 55 is aligned with the first sprocket 51 and the position where the one end 55a of the first chain 55 is aligned with the second sprocket 52 in the second direction D2. It is supposed to move. Therefore, the second fork 47 can be configured to move in the second direction D2 over a distance exceeding the dimension of the second fork 47 in the second direction D2, and the stroke of the second fork 47 can be increased. Accordingly, in the parking system in which the placement area 7 is provided on both sides of the transport carriage 31 and the stroke of the second fork 47 needs to be increased, the length dimension of the second fork 47 in the second direction D2. Thus, the transporter 3 can be made compact. As a result, the parking system 100 can be made compact.

  Further, since the driving force of the fork drive unit 58 is transmitted to the first fork 46 and the second fork 47 via the first chain 55, the second chain 56, and the third chain 57, the expansion and contraction of the fork main body 32 is achieved. Even when there is a step or gradient in the direction and the attitude of the fork main body 32 with respect to the carriage main body 41 changes, the driving force of the fork drive unit 58 is reliably transmitted to the first fork 46 and the second fork 47, and the fork main body 32 can be expanded and contracted smoothly.

  As shown in FIG. 2, the vehicle holding mechanism 34 is attached to the first fork 46 and holds the passenger automobile V. Hereinafter, an example of a detailed configuration of the vehicle holding mechanism 34 will be described, but the configuration is not limited to this configuration.

  The vehicle holding mechanism 34 holds the first holding portion 61 that holds one of the left and right front wheels Tf and the left and right rear wheels Tr of the passenger car V, and the other of the left and right front wheels Tf and the left and right rear wheels Tr of the passenger car V. A second holding unit 62 and a second holding unit driving mechanism 63.

  The first holding unit 61 includes a first base 71 and a pair of left and right holding mechanisms 72.

  As described above, the first base portion 71 is connected to one end portion 46 a of the first fork 46 via the pair of pins 48.

  Wheels 78 configured to support the first holding unit 61 and roll in the second direction D2 are attached to, for example, the four corners of the first base 71 viewed from the vertical direction. The wheel 78 supports the first holding unit 61 and the passenger vehicle V held on the first holding unit 61. The first base 71 is formed so as to cover the first fork 46, and is configured so that a gap is formed between the first fork 46. As a result, the load of the first holding unit 61 and the passenger vehicle V held on the first holding unit 61 is not applied to the first fork 46.

  Each holding mechanism 72 includes a pair of holding arms 73 and a holding arm drive mechanism 74.

  The holding arm 73 includes a shaft rod 75, an outer cylinder 76, and an auxiliary wheel 77. The shaft rod 75 is formed in a round bar shape, for example. The base end portion is attached so as to be swingable around an axis extending in the vertical direction. Then, the shaft rod 75 of the pair of sandwiching arms 73 includes a pair of the sandwiching angle position P1 extending in the direction intersecting the second direction D2, that is, the left or right of the first base 71, and the pair of sandwiching angle positions P1. The holding arm 73 is configured to swing between the release angle position P2 that swings in the direction in which the distal end portion thereof is separated.

  The outer cylinder 76 is formed in a cylindrical shape, for example, and is fitted and attached to the shaft rod 75 so as to be rotatable relative to the shaft rod 75 around the axis of the shaft rod 75. As a result, when the pair of sandwiching arms 73 are swung from the release angle position P2 to the sandwiching angle position P1, when the pair of sandwiching arms 73 come into contact with the wheels of the passenger car V, the outer cylinder 76 is brought into contact with the shaft rod 75. By rotating relative to the wheel, deformation of the wheel can be prevented. As a result, wheel damage or the like can be prevented.

  The auxiliary wheel 77 is attached to the tip end portion of the shaft rod 75 and is attached so as to be rotatable around the axis of the shaft rod 75. The auxiliary wheel 77 has a diameter larger than that of the outer cylinder 76, and at least when the holding arm 73 is located at the holding angle position P1, it is located on the same plane as the ground contact surface of the wheel 78. It is configured. Therefore, the load of the passenger car V is supported by the wheels 78 and the auxiliary wheels 77 in a state where the pair of sandwiching arms 73 located at the sandwiching angle position P1 holds the wheels of the passenger car V. Yes.

  The sandwiching arm drive mechanism 74 rotates one sandwiching arm 73 and the other sandwiching arm 73 in opposite directions to swing the pair of sandwiching arms 73 between the sandwiching angular position P1 and the release angular position P2. Mechanism. The sandwiching arm drive mechanism 74 is, for example, a rack and pinion mechanism (not shown), and one sandwiching mechanism in which a pinion gear that meshes with the rack is attached to the base end when the drive unit moves the rack in the second direction D2. The arm 73 is rotated in a predetermined direction, and the other holding arm 73 having a base end portion and a pinion gear meshing with the rack via a reversing gear is rotated in a direction opposite to the one holding arm 73. Has been. Then, by swinging the pair of sandwiching arms 73 from the release angle position P2 to the sandwiching angle position P1, the pair of sandwiching arms 73 advances forward and rearward of the corresponding wheels of the passenger car V, and the lower part of the wheels. Pinch. Thereby, the wheel moves so as to escape upward, and the passenger automobile V is lifted from the mounting surface. Further, by swinging the pair of sandwiching arms 73 from the sandwiching angle position P1 to the release angle position P2, the corresponding wheels of the passenger car V are lowered onto the placement surface, and the passenger automobile V is placed on the placement surface. Is done. Then, the pair of sandwiching arms 73 moves away from the front and rear of the corresponding wheel of the passenger car V. Thus, when the fork main body 32 is extended and shortened, the holding arm 73 located at the release angle position P2 and the wheels of the passenger car V can be prevented from interfering with each other.

  The second holding part 62 includes a second base part 81 and a pair of left and right holding mechanisms 72. Since the pair of left and right holding mechanisms 72 of the second holding unit 62 has the same configuration as the pair of left and right holding mechanisms 72 of the first holding unit 61, the same reference numerals are given and description thereof is omitted.

  The second base 81 is connected to the other end 46b of the first fork 46 through a second holding part drive mechanism 63 described later.

  Wheels configured to support the second holding unit 62 and roll in the second direction D2 are attached to, for example, the four corners of the second base 81 viewed from the vertical direction. Since this wheel has the same configuration as that of the wheel 78 of the first base 71, the same reference numerals are given and the description thereof is omitted.

  FIG. 6 is a diagram illustrating a configuration example of the second holding unit driving mechanism 63.

  The second holding unit driving mechanism 63 is a mechanism that moves the second holding unit 62 in the second direction D2. Hereinafter, an example of a detailed configuration of the second holding unit driving mechanism 63 will be described, but the configuration is not limited to this configuration.

  As shown in FIG. 6, the second holding unit driving mechanism 63 includes a guide chain 91 and a second holding unit driving unit 92 (see also FIG. 7).

  The guide chain 91 extends in the second direction D2, and one end and the other end thereof are fixedly attached to the first fork 46 by a guide chain end holding portion 94.

  10 and 11 are diagrams illustrating an operation example of the second holding unit driving mechanism 63. FIG.

  The second holding unit driving unit 92 is constituted by a motor, for example, and is fixedly attached to the second holding unit 62. A drive sprocket 93 that meshes with the guide chain 91 is attached to the output shaft of the second holding unit drive unit 92 via a speed reducer. Therefore, the second holding unit driving unit 92 rotates the drive sprocket 93 to move the second holding unit 62 along the guide chain 91, and the second holding unit 62 extends in the extending direction of the guide chain 91, that is, the first Move in two directions D2.

  As a result, the second holding unit drive mechanism 63 moves the second holding unit 62 to change the interval between the first holding unit 61 and the second holding unit 62 according to the wheel base of the passenger car V. it can. That is, when the passenger vehicle V1 having a relatively long wheel base WB1 as shown in FIG. 10 is held, the second holding unit drive mechanism 63 causes the first holding unit 61 and the second holding unit 62 to be separated from each other. 2 The holding part 62 is moved. Thus, the distance between the intermediate line L1 of the pair of holding arms 73 of the first holding part 61 and the intermediate line L3 of the pair of holding arms 73 of the second holding part 62 in the second direction D2 is set to the wheel base WB1 of the passenger car V1. Can be matched. Further, when the passenger automobile V2 having a relatively short wheel base WB2 as shown in FIG. 11 is held, the second holding part drive mechanism 63 is arranged so that the first holding part 61 and the second holding part 62 approach each other. The second holding part 62 is moved. Thus, the distance between the intermediate line L1 of the pair of holding arms 73 of the first holding part 61 and the intermediate line L3 of the pair of holding arms 73 of the second holding part 62 in the second direction D2 is set to the wheel base WB2 of the passenger car V2. Can be matched.

  The pair of guide sprockets 95 are attached to the second holding portion 62 so as to be located on both sides of the drive sprocket 93 in the second direction D2. The drive sprocket 93 is attached so as to rotate around a rotation axis extending in a direction orthogonal to the second direction D2. The pair of guide sprockets 95 guides the guide chain 91 so that the guide chain 91 and the drive sprocket 93 are securely engaged with each other.

  Further, the second holding unit driving unit 92 has a second brake 92a (see FIG. 7). By operating the second brake 92a, the output shaft of the second holding unit driving unit 92 is rotated. By restricting and releasing the second brake 92a, the rotation of the output shaft of the second holding unit drive unit 92 is allowed. Accordingly, the movement of the second holding portion 62 relative to the first fork 46 is restricted by operating the second brake 92a. Further, by releasing the second brake 92a, the second holding unit 62 can be moved in the second direction D2 by the driving force or the external force of the second holding unit driving unit 92.

  Since the second holding part 62 and the first fork 46 are connected via the guide chain 91 as described above, the first fork 46 and the second holding part 62 are relatively separated in the vertical direction. The guide chain 91 is bent and the guide chain 91 absorbs the displacement when the first fork 46 is inclined or when the inclination angle of the first fork 46 with respect to the second holding portion 62 changes. Thereby, the state where each wheel 78 and / or auxiliary wheel 77 of the second holding part 62 is grounded is maintained. As a result, it is possible to prevent this portion from being damaged by applying an excessive load to the connection portion between the first holding portion 61 and the first fork 46.

[Configuration example of control unit]
FIG. 7 is a block diagram schematically showing a configuration example of a control system of the parking system 100.

  The controller 6 included in the parking system 100 includes, for example, a control unit 21 having a computing unit such as a CPU and a storage unit 22 having a memory such as a ROM and a RAM. The controller 6 may be composed of a single controller that performs centralized control, or may be composed of a plurality of controllers that perform distributed control in cooperation with each other.

  The control unit 21 is a pair of right and left of the lifting platform driving mechanism 15, the cart driving mechanism 42, the fork driving unit 58 of the fork driving mechanism 33, the second holding unit driving unit 92 of the second holding unit driving mechanism 63, and the first holding unit 61. The holding arm driving mechanism 74 provided in each holding mechanism 72 and the holding arm driving mechanism 74 provided in each of the pair of left and right holding mechanisms 72 of the second holding unit 62 are driven.

  The storage unit 22 stores a predetermined control program, and the operation of the parking system 100 is controlled by the control unit 21 reading and executing these control programs. Moreover, the memory | storage part 22 is the position information of the left-right paired front wheel Tf and rear-wheel Tr of the receipt vehicle input from the detection sensor 11 linked | related with the identification information of the passenger car V (entrance vehicle), the identification information of the receipt vehicle, The actual vehicle / empty vehicle information of each placement area 7 associated with the vehicle identification information is stored.

[Operation example]
Next, an operation example of the parking system 100 will be described.

  First, the passenger car V driven by the driver enters the loading / unloading room 1 and is placed on the lifting platform 14. Here, the driver gets off the passenger car V and exits the loading / unloading room 1.

  Then, the control unit 21 measures the positions of the pair of left and right front wheels Tf and rear wheels Tr of the passenger car V on the lift 14 based on the signal input from the detection sensor 11, and stores the position information in the storage unit 22. Is stored.

  Next, the control unit 21 lowers the lifting platform 14 to position the lifting platform 14 on the level where the target placement area 7 is located.

  Next, the control unit 21 positions the transport carriage 31 in front of or behind the lifting platform 14 that is positioned at the level where the target placement region 7 is located.

  Next, the control unit 21 calculates the wheel base of the passenger car V based on the wheel position information stored in the storage unit 22. And the 2nd holding | maintenance part 62 is moved to the 2nd direction D2 so that the space | interval of the 1st holding | maintenance part 61 and the 2nd holding | maintenance part 62 in the 2nd direction D2 may correspond with the wheel base of the passenger car V.

  Next, the control unit 21 extends the fork main body 32 and inserts the fork main body 32 under the floor between the front wheels Tf and under the floor between the rear wheels Tr of the passenger car V. Based on the wheel position information stored in the storage unit 22, the first holding unit 61 and the second holding unit 62 are positioned between the pair of left and right front wheels Tf and between the pair of left and right rear wheels Tr.

  FIG. 12 is a flowchart illustrating an operation example of the fork drive unit 58 in the wheel clamping operation. FIG. 13 is a plan view illustrating an operation example of the fork drive unit 58 in the wheel clamping operation. FIG. 14 is a plan view showing an operation example of the second holding unit drive mechanism 63 in the wheel clamping operation.

  Next, the control unit 21 releases the pair of holding arms 73 of the pair of left and right holding mechanisms 72 of the first holding unit 61 and the pair of holding arms 73 of the pair of left and right holding mechanisms 72 of the second holding unit 62 at the release angle position. Swing from P2 toward the clamping angle position P1. Accordingly, the passenger car V is lifted from the elevator 14 and is held by the first holding part 61 and the second holding part 62.

  Then, the control unit 21 controls the first brake 58a of the fork drive unit 58 as follows when the pair of clamping arms 73 is rotated from the release angle position P2 toward the clamping angle position P1. 1 The position of the holding unit 61 is corrected.

  That is, first, when the control unit 21 starts swinging the pair of sandwiching arms 73, the control unit 21 determines whether or not the pair of sandwiching arms 73 is positioned at a predetermined angular position (step S12), and the pair of sandwiching arms 73. This determination is repeated until is positioned at a predetermined angular position (No in step S12).

  When it is determined that the pair of sandwiching arms 73 are positioned at a predetermined angular position (Yes in step S12), the first brake 58a of the fork drive unit 58 is released (step S13). For example, as shown in FIG. 13, due to a measurement error of the detection sensor 11, the intermediate line L <b> 1 of the pair of sandwiching arms 73 of the pair of left and right holding mechanisms 72 in the second direction D <b> 2 when viewed from the vertical direction. Does not coincide with the axis L2 of the front wheel Tf or the rear wheel Tr, and when only one of the pair of sandwiching arms 73 comes into contact with the corresponding wheel, the pair of sandwiching arms 73 is sandwiched therefrom. By rotating toward the angular position P1, the first holding portion 61 moves in the second direction D2 so that the intermediate line L1 of the pair of sandwiching arms 73 coincides with the wheel axis L2 of the passenger automobile V. In this way, by moving the pair of sandwiching arms 73 from the release angle position P2 to the sandwiching angle position P1, the first line is such that the intermediate line L1 of the pair of sandwiching arms 73 coincides with the wheel axis L2 of the passenger vehicle V. The position of the holding unit 61 can be corrected autonomously.

  Next, the control unit 21 determines whether or not the pair of sandwiching arms 73 is positioned at the sandwiching angle position P1 (step S14), and repeats this determination until the pair of sandwiching arms 73 is positioned at the sandwiching angle position P1. (No in step S14).

  When the control unit 21 determines that the pair of clamping arms 73 are located at the clamping angle position P1 (Yes in step S14), the control unit 21 operates the first brake 58a of the fork drive unit 58 (step S15). As a result, the movement of the first holding portion 61 relative to the carriage main body 41 is restricted.

  Further, the control unit 21 controls the second brake 92a of the second holding unit driving unit 92 when the pair of clamping arms 73 is rotated from the release angle position P2 toward the clamping angle position P1, and the pair of clamping arms 73 is controlled. The position of the second holding portion 62 is corrected so that the intermediate line L3 of the sandwiching arm 73 coincides with the wheel axis L4 of the passenger automobile V. Since this control is the same as steps S11 to S15, the description thereof is omitted.

  Then, when the pair of holding arms 73 of the first holding unit 61 and the second holding unit 62 are positioned at the holding angle position P1, the control unit 21 shortens the fork main body 32 and then moves the main body of the transporting carriage 31. The passenger automobile V is drawn into and positioned on the placement surface 41a of 41.

  Next, the control unit 21 moves the transport vehicle 31 in the first direction D1 and moves the passenger car V so that the passenger car V is positioned in front of the target placement region 7.

  Next, the control unit 21 extends the fork main body 32 and conveys the passenger car V onto the placement area 7.

  Next, the control unit 21 sandwiches the pair of sandwiching arms 73 of the pair of left and right holding mechanisms 72 of the first holding unit 61 and the pair of sandwiching arms 73 of the pair of left and right holding mechanisms 72 of the second holding unit 62. Swing from P1 toward the release angle position P2. As a result, the passenger car V is lowered and placed in the placement area 7.

  Next, the control unit 21 shortens the fork main body 32 and positions the first holding unit 61 and the second holding unit 62 on the carriage main body 41.

  Thus, the parking system 100 conveys the vehicle located in the loading / unloading room 1 to the placement area 7.

  In addition, when the vehicle located in the loading area 7 is transported to the loading / unloading chamber 1, the control unit 21 performs the fork drive of the lifting platform drive mechanism 15, the cart drive mechanism 42, and the fork drive mechanism 33 according to the procedure reverse to the above procedure. 58, the second holding unit driving unit 92 of the second holding unit driving mechanism 63, the holding arm driving mechanism 74 provided in the pair of left and right holding mechanisms 72 of the first holding unit 61, and the left and right of the second holding unit 62 By driving the holding arm driving mechanism 74 provided in each of the pair of holding mechanisms 72, the passenger car V is transported from the placement area 7 to the loading / unloading chamber 1.

  As described above, in the parking system 100 of the present invention, the second fork 47 has a position where the other end 55b of the first chain 55 is aligned with the first sprocket 51 in the second direction D2, and one end of the first chain 55. 55a moves between positions aligned with the second sprocket 52. Therefore, the second fork 47 can be configured to move in the second direction D2 over a distance exceeding the dimension of the second fork 47 in the second direction D2, and the stroke of the second fork 47 can be increased. Accordingly, in the parking system in which the placement area 7 is provided on both sides of the transport carriage 31 and the stroke of the second fork 47 needs to be increased, the length dimension of the second fork 47 in the second direction D2. Thus, the transporter 3 can be made compact. As a result, the parking system 100 can be made compact.

  Further, since the driving force of the fork drive unit 58 is transmitted to the first fork 46 and the second fork 47 via the first chain 55, the second chain 56, and the third chain 57, the expansion and contraction of the fork main body 32 is achieved. Even when there is a step or gradient in the direction and the attitude of the fork main body 32 with respect to the carriage main body 41 changes, the driving force of the fork drive unit 58 is reliably transmitted to the first fork 46 and the second fork 47, and the fork main body 32 can be expanded and contracted smoothly.
