Description

[Technical Field]

[0001] The present invention relates to a pallet for a mechanical parking device and a mechanical parking device. [Background technology]

[0002] Mechanical parking systems are used to park multiple vehicles in a limited space. Mechanical parking systems are installed underground in apartment buildings, office buildings, shopping centers, etc., or above ground adjacent to the buildings.

[0003] An underground parking system is an example of a mechanical parking system. A horizontal circulation type parking system (hereinafter referred to as a "horizontal circulation type parking system") is an example of an underground parking system.

[0004] The horizontal circulation parking system comprises a loading / unloading section, pallets, a lift, and multiple storage sections. The loading / unloading section is a space where vehicles are loaded and unloaded. Vehicles that have been loaded forward from the loading / unloading section are placed (loaded) on the pallets. The pallets are transported up and down the elevator shaft by the lift rising and falling, and are also transported horizontally through the underground storage space. The elevator shaft is a vertical transport path for the pallets that connects the loading / unloading section and the storage floor where the storage sections are located. The shape of the pallet in a plan view is rectangular. The pallet is transported in the longitudinal direction of the pallet (the front-to-rear direction of the vehicle placed on the pallet) and the lateral direction of the pallet (the width direction of the vehicle placed on the pallet). The operation of transporting the pallet in the longitudinal direction is called "vertical feeding," and the operation of transporting the pallet in the lateral direction is called "horizontal feeding." The lift raises and lowers pallets with vehicles placed on them or pallets without vehicles placed on them (hereinafter referred to as "empty pallets") in the hoistway. The storage section is an area on the storage floor where pallets (including empty pallets) are stored. The storage section is divided into multiple storage spaces.

[0005] When a pallet carrying a vehicle is transported vertically, the vehicle may move from its resting position on the pallet due to acceleration caused by the vertical transport or inertia caused by the pallet stopping during transport (movement). In other words, when a pallet carrying a vehicle is transported vertically, the position of the vehicle's tires may be displaced. Such displacement of tire position is particularly likely to occur when the parking brake of the vehicle placed on the pallet is forgotten to be applied. If the tire position is displaced during vertical transport, the vehicle may fall off the pallet. To solve this problem, a pallet has been proposed in which tire chocks (wheel stop devices) that restrict the movement of the vehicle's tires are arranged on the top surface of the pallet (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-129374

[0007] The tire stopper (car stop device) disclosed in Patent Document 1 includes multiple rod-shaped members (car stoppers) fixed to the top surface of a pallet. The multiple rod-shaped members are arranged at predetermined intervals on one side of the shorter side (for example, on the side of the vehicle's right front tire) at the front end side of the pallet's length (the front side in the direction of entry when a vehicle advances onto the pallet). The spaces between each rod-shaped member on the top surface of the pallet form tire stopping positions. The stopping positions are positions where the tire (right front tire) of a vehicle placed on the pallet is placed. The rod-shaped members arranged before and after the stopping positions restrict longitudinal displacement of the tire when the vehicle is placed on the pallet (when the tire is placed at the stopping position).

[0008] The tire stopper disclosed in Patent Document 1 has rod-shaped members positioned in front and behind the tire when the vehicle is placed on the pallet. The tire stopper disclosed in Patent Document 1 can restrict the tire's longitudinal displacement with the rod-shaped members even if acceleration or inertia occurs during vertical transport of the pallet. As a result, the vehicle is prevented from falling off the pallet.

[0009] In recent years, there has been a demand for barrier-free pallets to make it easier for vehicles to enter (store) pallets. Barrier-free pallets can be achieved by eliminating tire chocks. However, with pallets without tire chocks, the problem of vehicles falling off the pallet during vertical transport cannot be solved. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, with reference to the drawings, an embodiment of a pallet for a mechanical parking device and a mechanical parking device according to the present invention will be described.

[0015] The embodiment described below is an example in which the mechanical parking system according to the present invention (hereinafter referred to as "the system") is a horizontal circulation type parking system that allows forward parking.

[0016] In the following description, the direction in which the vehicle approaches the pallet (hereinafter referred to as the "approaching direction") is the "forward" direction in this specification, and the opposite direction to the approaching direction is the "rear" direction in this specification. The left side of the approaching direction is the "left" direction in this specification, and the right side of the approaching direction is the "right" direction in this specification.

[0017] ●Mechanical parking device● ●Configuration of mechanical parking device FIG. 1 is a cross-sectional view showing an embodiment of the present device. The figure shows a schematic diagram of multiple vehicles stored (parked) in an underground storage space. The storage space is provided on multiple floors (two floors). The specific structure of the pallets, which will be described later, is not shown in the figure.

[0018] The device 1 stores a plurality of vehicles C (C1, C2). The device 1 includes a storage space SP, an elevator shaft UD, a pallet 10, an entry / exit section 20, an entry / exit gate 30, a lift 40, a transport device 50, a pallet support section 60 (see FIG. 3), an anti-tilt stopper 70 (see FIG. 3), and a drive device 80 (see FIG. 3). The device 1 stores the vehicles C (C1, C2) by transporting the pallet 10 in the forward / backward and left / right directions in the underground storage space SP.

[0019] For example, vehicle C1 is a vehicle with a long front overhang. Vehicle C2 is a vehicle with a short front overhang (shorter than vehicle C1). In the following description, when there is no need to particularly distinguish between vehicles C1 and C2, the term "vehicle" will be collectively referred to as vehicle C.

[0020] "Front overhang" is the horizontal distance from the centerline of the front tire axle to the very front end of the vehicle.

[0021] The storage space SP stores multiple vehicles C. The storage space SP has multiple storage floors (first storage floor B1, second storage floor B2). The first storage floor B1 is located above the second storage floor B2 (on the ground level: the upper side of the paper in FIG. 1). The second storage floor B2 is located below the first storage floor B1. That is, for example, the first storage floor B1 is the first basement floor. The second storage floor B2 is the second basement floor.

[0022] 2, the first storage floor B1 includes a plurality of storage sections B11, B12, ... B1n (n = integer). Each of the plurality of storage sections stores a pallet 10 (10a, 10b, ..., 10i, 10z) and a vehicle C placed on the pallet 10.

[0023] The second storage floor B2, like the first storage floor B1, is equipped with a plurality of storage sections.

[0024] In the present invention, the number of storage floors arranged in the storage space is not limited to "2." That is, for example, the number of storage floors may be "1," or may be "3" or more.

[0025] The elevator shaft UD is a passageway that connects the loading / unloading section 20 and the storage space SP. A lift 40 moves up and down in the elevator shaft UD.

[0026] FIG. 2 is a schematic plan view showing the storage space SP. The figure shows a schematic plan view of the first storage floor B1 in the storage space SP. However, for ease of explanation, the vehicle C is omitted from the illustration. The figure shows that the first storage floor B1 includes 11 storage sections B1-B111. The figure shows that pallets 10 are placed in 9 of the 11 storage sections B1-B111. In other words, the first storage floor B1 shows that two empty spaces are placed. In other words, the device 1 can store 9 vehicles C on the first storage floor B1. The configuration of the storage sections placed on the second storage floor B2 is the same as the configuration of the storage sections placed on the first storage floor B1.

[0027] In the present invention, the number of storage sections arranged on each storage floor and the number of vehicles that can be stored in each storage section are not limited to the above-mentioned numbers.

[0028] The following description of the configuration of the device 1 will also refer to Figure 1. In the following description, the planar (horizontal) transportation of pallets 10 will be described using the case where they are transported on the first storage floor B1 as an example. In the following description, when describing individual pallets specifically, they will be described with individual reference numerals (10a-10i, 10z), and when describing pallets collectively, they will be described simply as pallet 10.

[0029] The pallets 10 (10a-10i, 10z) are used to place vehicles C. The pallets 10 are placed movably on the lift 40 and on one of the storage sections B11-B111 via the transport device 50. The pallets 10 are transported between the loading / unloading section 20 and the storage space SP, and move horizontally on the first storage floor B1. The shape of the pallets is rectangular in plan view. The pallets 10 are an example of a pallet for a mechanical parking device of the present invention. The specific configuration of the pallets 10 will be described later.

[0030] The loading / unloading section 20 is a space where the vehicle C enters and leaves the garage. The loading / unloading section 20 is located, for example, on the ground floor. When entering the garage, the vehicle C enters the loading / unloading section 20. When leaving the garage, the vehicle C leaves the garage forward from the loading / unloading section 20. The loading / unloading section 20 has a platform 21 and an opening 22h.

[0031] The platform 21 forms the floor of the loading / unloading area 20.

[0032] The opening 22h is a rectangular hole that connects the loading / unloading section 20 (the space excluding the opening 22h) with the elevator shaft UD. The pallet 10 is transported between the loading / unloading section 20 and the elevator shaft UD through the opening 22h. The opening 22h is placed on the platform 21. The opening area of the opening 22h is slightly larger than the planar area of the pallet 10. When the vehicle C is ready to load / unload the loading / unloading section 20, the pallet 10 is placed at the opening 22h. In other words, the position of the opening 22h is an entry position where the vehicle C can enter the pallet 10. When the pallet 10 is placed at the opening 22h, the upper surface (surface) of the platform 21 forms a substantially flat surface with the upper surface (surface) of the pallet 10.

[0033] The entrance / exit section is not limited to a configuration that allows a vehicle to enter or exit the parking lot in a forward direction. For example, the entrance / exit section may be a configuration that allows a vehicle to enter or exit the parking lot in a backward direction.

[0034] The entrance / exit 30 is an entrance / exit for the vehicle C to / from the entrance / exit section 20. The entrance / exit 30 is provided with an openable / closable door 31.

[0035] The door 31 prevents the movement of the vehicle C between the inside and outside of the loading / unloading section 20. The door 31 opens and closes when an operation panel (not shown) is operated by a user of the device 1, an administrator of the device 1, or the like. That is, for example, when the door 31 is "open," the vehicle C can move between the inside and outside of the loading / unloading section 20. When the door 31 is "closed," the vehicle C cannot move between the inside and outside of the loading / unloading section 20. The door 31 is located behind the vehicle C that has advanced into the loading / unloading section 20.

[0036] The "user" is, for example, the driver or passenger of the vehicle C. The "manager" is, for example, a person who guides the user of the device 1 in entering and leaving the facility, or a manager or maintenance person of the device 1.

[0037] The lift 40 raises and lowers the pallet 10 in the elevator shaft UD, moving the pallet 10 between the loading / unloading section 20, the first storage floor B1, and the second storage floor B2. The lift 40 moves the pallet 10 to the opening 22h (storage position) of the loading / unloading section 20. The lift 40 places the pallet 10 via the conveying device 50. The pallet 10 placed on the lift 40 is a pallet on which a vehicle C is placed, or an empty pallet. The lift 40 is equipped with a swivel unit (not shown).

[0038] The swivel unit swivels the pallet 10.

[0039] In addition, the loading / unloading section does not need to be equipped with a turning section.

[0040] The conveying device 50 conveys the pallets 10 horizontally (front-back and left-right) on the first storage floor B1. The conveying device 50 is equipped with drive rollers 51. The drive rollers 51 are rotated by the power of a drive device (not shown). The drive rollers 51 support the underside of the pallet 10 (vertical rails 12a and horizontal rails 12b described below). The conveying device 50 is equipped with a first conveying device 50a mounted on the lift 40 and a second conveying device 50b mounted on each of the storage sections B11-B111. The configuration of the first conveying device 50a is the same as the configuration of the second conveying device 50b. That is, the first conveying device 50a is equipped with drive rollers 51a, and the second conveying device 50b is equipped with drive rollers 51b.

[0041] The first conveying device 50a moves the pallet 10 placed on the lift 40 over the drive rollers 51a by the rotation of the drive rollers 51a, and conveys it to the second conveying device 50b. The second conveying device 50b moves the pallet 10 placed on the second conveying device 50b over the drive rollers 51b by the rotation of the drive rollers 51b, and conveys it to another second conveying device 50b or the first conveying device 50a.

[0042] The pallet 10 is transported in the front-to-back direction (longitudinal direction) and left-to-right direction (transverse direction) on the first storage floor B1 by the rotation of the drive rollers 51a, 51b. The operation of transporting the pallet 10 in the front-to-back direction is called "vertical feeding," and the operation of transporting the pallet 10 in the left-to-right direction is called "horizontal feeding."

[0043] FIG. 3 is a schematic plan view of the entrance position of the vehicle C in the entrance / exit section 20. As shown in FIG. FIG. 4 is an enlarged schematic side view of the pallet support portion 60. As shown in FIG. Figure 5 is a schematic plan view showing the operation of the pallet support unit 60 at the storage position of vehicle C, where (a) shows the pallet support unit 60 in the pallet support position, and (b) shows the pallet support unit 60 in the retracted position.

[0044] For ease of explanation, the pallet 10 and the vehicle C are omitted from Figures 3, 4, 5(a), and 5(b). Also, for ease of explanation, the first stopper portion 72, the second stopper portion 73, and the third stopper portion 74 are omitted from Figures 5(a) and 5(b).

[0045] The pallet support parts 60 support the pallet 10 placed in the opening 22h (storage position). The pallet support parts 60 are arranged and fixed to the underside (underground surface) of the platform 21 so as to support the pallet 10 at two points on each of the front and rear ends. In other words, the number of pallet support parts 60 is "4." The pallet support parts 60 arranged on the front side of the platform 21 are spaced apart in the direction along the short side of the pallet 10 when the pallet 10 is placed in the opening 22h. Similarly, the pallet support parts 60 arranged on the rear side of the platform 21 are spaced apart in the direction along the short side of the pallet 10 when the pallet 10 is placed in the opening 22h.

[0046] Each pallet support section 60 is driven by a drive device 80 to be able to move back and forth between a pallet support position and a retracted position.

[0047] The "pallet support position" is a position that supports the pallet 10. As shown in FIG. 5(a), when the pallet support part 60 is in the pallet support position, a portion of the pallet support part 60 is located within the opening 22h in a plan view. In other words, when the pallet support part 60 is in the pallet support position, the pallet 10 is supported by the pallet support part 60. The pallet support position is an example of a "support position" in the present invention.

[0048] The "retracted position" is a position where support for the pallet 10 is released and the pallet 10 is allowed to pass through the opening 22h. When the pallet support part 60 is in the retracted position, the pallet support part 60 is positioned so as to overlap with the platform 21 in a plan view (see, for example, FIG. 5(b)).

[0049] When the pallet 10 is placed in the opening 22h, the pallet support section 60 advances to the pallet support position. When the pallet 10 moves out of the opening 22h (when it has moved), the pallet support section 60 retreats to the retreat position.

[0050] Each pallet support portion 60 includes a main body portion 61 , an arm portion 62 , and a protrusion portion 63 .

[0051] The main body 61 is disposed on the lower surface of the platform 21 and fixed thereto.

[0052] The arm portion 62 is attached to the main body portion 61 and is movable back and forth between a pallet support position and a retracted position. The arm portion 62 is a plate-shaped member.

[0053] The protrusion 63 is disposed on the upper surface (the surface facing upward in FIG. 4) of the arm portion 62. The protrusion 63 supports the underside of the pallet 10 when the pallet support portion 60 is in the pallet support position. The protrusion 63 is, for example, a square steel pipe.

[0054] The tilt prevention stopper 70 restricts the swinging of the tire stoppers 17 (see FIG. 6; a first swinging plate 171 and a second swinging plate 173, which will be described later) of the pallet 10. The tilt prevention stopper 70 is arranged (attached) to the tip of the front right pallet support section 60 out of the four pallet support sections 60. In other words, the number of tilt prevention stoppers 70 is "1". Driven by the drive unit 80, the tilt prevention stopper 70 is able to move back and forth between a swing restriction position and a swing restriction release position together with the advance and retreat of the pallet support section 60.

[0055] The "swing restriction position" is a position that restricts the swing of the tire stopper 17. When the tilt prevention stopper 70 is in the swing restriction position, the tilt prevention stopper 70 is located within the opening 22h in a plan view. The swing restriction position is an example of the "restriction position" in the present invention.

[0056] The "swing restriction release position" is a position where the restriction on the swing of the tire stopper 17 is released, allowing the tire stopper 17 to swing. When the tilt prevention stopper 70 is in the swing restriction release position, the position of the tilt prevention stopper 70 is a position where it overlaps with the platform 21 in a plan view (see, for example, FIG. 5(b)). The swing restriction release position is an example of the "restriction release position" in the present invention.

[0057] When the pallet 10 is placed in the opening 22h, the tilt prevention stopper 70 advances to the swing restriction position, and when the pallet 10 moves out of the opening 22h (when it has moved), the tilt prevention stopper 70 Oscillation restriction release That is, when the pallet 10 is placed in the opening 22h, the pallet support portion 60 advances to the pallet support position, and the tilt prevention stopper 70 advances to the swing restriction position. Similarly, when the pallet 10 moves (has moved) from the opening 22h, the pallet support portion 60 Oscillation restriction release The tilt prevention stopper 70 is Oscillation restriction release Evacuate to a position.

[0058] The tilt prevention stopper 70 includes a base portion 71 , a first stopper portion 72 , a second stopper portion 73 , and a third stopper portion 74 .

[0059] The base portion 71 is a plate-like member that is placed (attached) to the tip of the arm portion 62. In other words, the base portion 71 and the arm portion 62 form a single plate-like member.

[0060] The first stopper portion 72, the second stopper portion 73, and the third stopper portion 74 each restrict the swinging of the tire stopper 17. The first stopper portion 72, the second stopper portion 73, and the third stopper portion 74 are each disposed on the upper surface of the base portion 71 (the surface facing upward in the plane of the paper in FIG. 4). The first stopper portion 72, the second stopper portion 73, and the third stopper portion 74 each support the lower surface of the tire stopper 17. The first stopper portion 72, the second stopper portion 73, and the third stopper portion 74 are each, for example, columnar members.

[0061] The drive device 80 advances and retreats the pallet support section 60 between the pallet support position and the retracted position, and advances and retreats the tilt prevention stopper 70 between the swing restriction position and the swing restriction release position. That is, the drive device 80 advances and retreats the pallet support section 60 between the pallet support position and the retracted position at the same time as advancing and retreating the tilt prevention stopper 70. That is, when the drive device 80 advances the tilt prevention stopper 70 to the swing restriction position, the drive device 80 advances the pallet support section 60 to the pallet support position, and when the drive device 80 retracts the tilt prevention stopper 70 to the swing restriction release position, the drive device 80 retracts the pallet support section 60 to the retracted position. The drive device 80 drives the pallet support sections 60 arranged on the front side of the platform 21 between each other, and between the pallet support sections 60 arranged on the front side of the platform 21. backward The drive units 80 are arranged and fixed to the underside of the platform 21 between the pallet support units 60 arranged on the side. That is, the number of drive units 80 is "2". The drive units 80 are, for example, motors. The drive units 80 include a link mechanism 81.

[0062] The link mechanism 81 connects the drive unit 80 to each of the pallet support units 60 arranged on both sides of the drive unit 80. The link mechanism 81 driven by the drive unit 80 moves the arm unit 62 (pallet support unit 60) forward and backward. In other words, the link mechanism 81 driven by the drive unit 80 moves the base unit 71 (tilt prevention stopper 70) forward and backward.

[0063] ●Pallets for mechanical parking systems FIG. 6 is a plan view of a pallet 10 of the mechanical parking device according to the present invention. FIG. 7 is a cross-sectional view of the pallet 10 taken along line AA. FIG. 8 is a cross-sectional view of the pallet 10 taken along line BB.

[0064] The pallet 10 comprises a pallet body 11, vertical rails 12a, horizontal rails 12b, a turning portion 13, a vertical frame 14, a horizontal frame 15, an opening 16h, a tire stopper 17, a first swing adjustment plate 18, and a second swing adjustment plate 19.

[0065] A vehicle C (see FIG. 1) is placed on the pallet body 11. The pallet body 11 is, for example, a plate-like member made of steel. The pallet body 11 has a rectangular shape.

[0066] The vertical rails 12a are arranged on the underside (backside) of the pallet body 11 and extend in the longitudinal direction of the pallet body 11 (the vertical direction on the paper in FIG. 6). The vertical rails 12a are supported by the drive rollers 51 when the pallet 10 is fed vertically. The vertical rails 12a are, for example, H-shaped steel, and are made of the same steel material as the pallet body 11. Two vertical rails 12a are arranged with a gap between them in the short side direction of the pallet body 11 (the horizontal direction on the paper in FIG. 6). The vertical rails 12a are discontinuous at a predetermined location in the longitudinal direction.

[0067] The horizontal rail 12b is disposed on the underside (back surface) of the pallet body 11 and extends in the short side direction (left-right direction on the paper in Figure 6). The horizontal rail 12b is supported by the drive roller 51 when the pallet 10 is fed laterally. The horizontal rail 12b is, for example, an H-shaped steel, and is made of the same steel material as the pallet body 11. Two horizontal rails 12b are disposed with a gap in the longitudinal direction. The horizontal rails 12b are discontinuous at a predetermined location in the short side direction. The discontinuous location of the horizontal rail 12b is the intersection with the discontinuous location of the vertical rail 12a. A turning portion 13 is disposed between the discontinuous location of the vertical rail 12a and the discontinuous location of the horizontal rail 12b.

[0068] The turning units 13 change the conveying direction of the pallets 10 to switch between vertical feeding and horizontal feeding. The turning units 13 are arranged at intersections. The number of turning units 13 is, for example, "4." The turning units 13 are equipped with turning rails (not shown).

[0069] The diverting rail is disposed on the underside of the pallet body 11 at the diverting section 13. The diverting rail rotates between the longitudinal direction and the lateral direction of the pallet body 11, with a rotation axis in a direction perpendicular to the planar direction of the pallet body 11 (the direction toward the front of the paper in FIG. 6). That is, the diverting rail can be switched between facing the longitudinal direction and facing the lateral direction. That is, when the diverting rail faces the longitudinal direction, it is located on an extension of the vertical rail 12a, and when the diverting rail faces the lateral direction, it is located on an extension of the horizontal rail 12b. In other words, when the diverting rail faces the longitudinal direction, the pallet 10 is fed longitudinally, and when the diverting rail faces the lateral direction, the pallet 10 is fed transversely.

[0070] The vertical frame 14 is disposed on the underside (rear surface) of the pallet body 11 and extends in the longitudinal direction. The vertical frame 14 is disposed along both short sides of the pallet body 11. The ends of the horizontal rails 12b are disposed (fixed) to the vertical frame 14. The vertical frame 14 is made of the same steel material as the pallet body 11, for example, a square steel pipe.

[0071] The horizontal frames 15 are disposed on the underside (rear surface) of the pallet body 11 and extend in the short direction. The horizontal frames 15 are disposed along both longitudinal sides of the pallet body 11. The horizontal frames 15, together with the vertical frames 14, reinforce the strength of the pallet 10. The ends of the vertical rails 12a are disposed (fixed) to the horizontal frames 15. The horizontal frames 15 are, for example, square steel pipes, and are made of the same steel material as the pallet body 11.

[0072] A tire stopper 17 is placed in the opening 16h. The opening 16h is a rectangular hole formed on the front right side of the pallet body 11. The opening area of the opening 16h is slightly larger than the combined planar area of a first rocking plate 171 and a second rocking plate 173, which will be described later.

[0073] The tire stopper 17 restricts displacement of the vehicle C placed on the pallet 10, i.e., restricts movement of the tire T of the vehicle C on the pallet 10. The tire stopper 17 is disposed in the opening 16h. That is, the tire stopper 17 restricts movement of the right front tire T of the vehicle C.

[0074] The tire stopper 17 includes a first swing plate 171 , a first swing shaft 172 , a second swing plate 173 , and a second swing shaft 174 .

[0075] The first rocking plate 171 is disposed in the opening 16h and rocks. The first rocking plate 171 is rectangular in plan view and is an isosceles trapezoid in side view. The planar area of the first rocking plate 171 is approximately two-thirds the size of the opening area of the opening 16h. In other words, the planar area of the first rocking plate 171 is smaller than the opening area of the opening 16h. The first rocking plate 171 is disposed on the rear side within the opening 16h. The first rocking plate 171 rocks (tilts) rearward and forward around a first rocking shaft 172 as a fulcrum. The first rocking plate 171 is made of the same steel material as the pallet body 11. The first rocking plate 171 is an example of a rocking plate defined in the present invention.

[0076] When the first rocking plate 171 rocks rearward about the first rocking shaft 172 as a fulcrum, the rear side of the first rocking plate 171 drops into the opening 16h, and the front side of the first rocking plate 171 protrudes from the upper surface of the pallet body 11. On the other hand, when the first rocking plate 171 rocks forward about the first rocking shaft 172 as a fulcrum, the rear side of the first rocking plate 171 protrudes from the upper surface of the pallet body 11, and the front side of the first rocking plate 171 drops into the opening 16h.

[0077] When a pallet 10 is placed in the opening 22h (when the pallet 10 is placed in the storage position), the tilt prevention stopper 70 is advanced to the swing restriction position, and therefore the swing of the first swing plate 171 is restricted by the first stopper portion 72 and the second stopper portion 73. That is, the rearward swing of the first swing plate 171 is restricted by the first stopper portion 72, and the forward swing of the first swing plate 171 is restricted by the second stopper portion 73. When the swing of the first swing plate 171 is restricted, the upper surface of the pallet body 11 is flat.

[0078] When the pallet 10 is not placed in the opening 22h (when the pallet 10 has moved out of the opening 22h), the first rocking plate 171 is released from the restriction by the tilt prevention stopper 70 and rocks. When the first rocking plate 171 is rocking with the vehicle C placed on the pallet 10, the first rocking plate 171 restricts the movement of the right front tire T of the vehicle C (particularly vehicle C1).

[0079] The first swing shaft 172 supports the first swing plate 171 so that it can swing within the opening 16h. The first swing shaft 172 is disposed to pass through a shaft hole (not shown) of the first swing plate 171, thereby supporting the first swing plate 171 so that it can swing in a seesaw manner around the first swing shaft 172. One end of the first swing shaft 172 is attached (joined) to the vertical rail 12a, and the other end is attached (joined) to the vertical frame 14. That is, the first swing shaft 172 extends in the short direction of the pallet main body 11. That is, the extending direction (axial direction) of the first swing shaft 172 is a direction perpendicular to the entry direction. The first swing shaft 172 is an example of a swing shaft in the present invention.

[0080] The "approaching direction" refers to a direction intersecting the short side direction of the pallet 10 (not limited to a direction perpendicular to the short side direction), and is broadly interpreted to mean any direction intersecting the short side direction of the pallet 10. In other words, a direction perpendicular to the short side direction of the pallet 10, as well as any direction other than a direction perpendicular to the short side direction of the pallet 10, are all "approaching directions." In other words, even when "vehicle C approaches pallet 10 at a slight angle," the approaching direction is a direction along the longitudinal direction of the pallet 10.

[0081] The second rocking plate 173 is disposed in the opening 16h and rocks. The second rocking plate 173 is rectangular in plan view and a right-angled trapezoid in side view. The plane area of the second rocking plate 173 is approximately one-third the size of the opening area of the opening 16h. That is, the plane area of the second rocking plate 173 is smaller than the opening area of the opening 16h and smaller than the plane area of the first rocking plate 171. The second rocking plate 173 is disposed on the front side within the opening 16h. That is, the second rocking plate 173 is disposed forward of the first rocking plate 171. The second rocking plate 173 rocks rearward about the second rocking shaft 174. When the second rocking plate 173 rocks rearward about the second rocking shaft 174, the rear side of the second rocking plate 173 falls into the opening 16h. The second swing plate 173 is made of the same steel material as the pallet body 11.

[0082] When the pallet 10 is placed in the opening 22h (when the pallet 10 is placed in the storage position), the tilt prevention stopper 70 is advanced to the swing restriction position, and therefore the rearward swing of the second swing plate 173 is restricted by the third stopper portion 74. When the swing of the second swing plate 173 is restricted, the upper surface of the pallet body 11 is flat.

[0083] When the pallet 10 is not placed in the opening 22h (when the pallet 10 has moved out of the opening 22h), the second rocking plate 173 is released from the restriction by the tilt prevention stopper 70 and rocks. When the second rocking plate 173 is rocking with the vehicle C placed on the pallet 10, the second rocking plate 173 restricts the movement of the right front tire T of the vehicle C (particularly vehicle C2).

[0084] The second swing shaft 174 swingably supports the second swing plate 173 within the opening 16h. The second swing shaft 174 is disposed to pass through a shaft hole (not shown) of the second swing plate 173, thereby supporting the second swing plate 173 swingably in a cantilever manner with the second swing shaft 174 as a fulcrum. One end of the second swing shaft 174 is attached (joined) to the vertical rail 12a, and the other end is attached (joined) to the vertical frame 14. That is, the second swing shaft 174 extends in the short direction of the pallet main body 11. That is, the extending direction (axial direction) of the second swing shaft 174 is parallel to the extending direction (axial direction) of the first swing shaft 172. The second swing shaft 174 is disposed forward of the first swing shaft 172.

[0085] The first swing adjusting plate 18 restricts the swing range of the first swing plate 171. The first swing adjusting plate 18 is a plate-shaped member having one longitudinal side (rear side) attached (joined) to the horizontal rail 12b and the other longitudinal side (front side) protruding forward. That is, the first swing adjusting plate 18 is supported by the horizontal rail 12b in a cantilever manner. When the first swing plate 171 swings rearward about the first swing shaft 172 as a fulcrum, the first swing adjusting plate 18 supports the rear portion of the first swing plate 171 and restricts the swing range of the first swing plate 171 toward the rear. That is, the maximum swing range of the first swing plate 171 toward the rear is limited to the first swing adjusting plate 18. In other words, when the first rocking plate 171 rocks rearward, the rear portion of the first rocking plate 171 does not go lower than the lower end of the horizontal rail 12b (the end on the right side of the paper in FIG. 7).

[0086] The second swing adjustment plate 19 restricts the swing range of the first swing plate 171 and also restricts the swing range of the second swing plate 173. One end of the second swing adjustment plate 19 is attached (joined) to the vertical rail 12a, and the other end is attached (joined) to the vertical frame 14 (the lower surface of the vertical frame 14). When the second swing plate 173 swings rearward about the second swing shaft 174 as a fulcrum, the second swing adjustment plate 19 supports the rear part of the second swing plate 173, thereby restricting the swing range of the second swing plate 173 toward the rear side. In addition, when the first swing plate 171 swings forward about the first swing shaft 172 as a fulcrum, the second swing adjustment plate 19 supports the front part of the first swing plate 171, thereby restricting the swing range of the first swing plate 171 toward the front side. That is, the maximum swing range of the second rocking plate 173 toward the rear side is up to the second rocking adjustment plate 19. The maximum swing range of the first rocking plate 171 toward the front side is up to the second rocking adjustment plate 19. In other words, when the second rocking plate 173 swings toward the rear side and when the first rocking plate 171 swings toward the front side, the rear end of the second rocking plate 173 and the rear end of the first rocking plate 171 do not go lower than the lower end of the vertical rail 12a (the end on the lower side of the paper in FIG. 8).

[0087] ● Operation of mechanical parking devices Next, the operation of the device 1 will be described together with the operation of the vehicle C parked in the device 1.

[0088] ●Receiving operation First, after vehicle C is parked in front of door 31 of loading / unloading entrance 30, when a user or manager operates the operation panel, device 1 causes conveying device 50 to convey empty pallet 10 (pallet 10z) within storage space SP, and causes lift 40 to lift empty pallet 10 (pallet 10z) within elevator shaft UD to opening 22h of loading / unloading section 20. At this time, first swing plate 171 and second swing plate 173 are both in a swinging state. Lift 40 lifts pallet 10z slightly above opening 22h (to a position where the bottom surface of pallet body 11 is higher than the top surface of platform 21). At this time, pallet support section 60 is in the retracted position, and tilt prevention stopper 70 is in the swing restriction release position.

[0089] Next, the pallet support part 60 advances from the retracted position to the pallet support position by the drive device 80. At this time, the tilt prevention stopper 70 advances together with the pallet support part 60 from the swing restriction release position to the swing restriction position.

[0090] After the pallet support parts 60 and the tilt prevention stoppers 70 have advanced to their corresponding positions, the lift 40 lowers the pallet 10z to the position of the opening 22h, and the pallet 10z is supported by the pallet support parts 60. At this time, the swinging of the first swing plate 171 and the second swing plate 173 is restricted by the tilt prevention stoppers 70, and the top surface of the pallet body 11 becomes flat.

[0091] When the pallet 10z is placed in the opening 22h of the loading / unloading section 20, the door 31 opens.

[0092] FIG. 9 is a schematic side view showing a state in which the vehicle C has entered the entrance / exit section 20. As shown in FIG. 10. This figure shows a state in which a vehicle C1 with a long front overhang is placed on the pallet 10z, and the right front tire T is placed on the upper surface of the first swing plate 171.

[0093] Next, when the vehicle C1 enters the loading / unloading section 20 from the loading / unloading entrance 30, the device 1 provides instructions such as "go forward," "backward," and "stop" to the driver of the vehicle C1 by voice guidance from a speaker (not shown) or by displaying instructions on a display panel (not shown). When the vehicle C1 enters the loading / unloading section 20 from the loading / unloading entrance 30 and stops at a predetermined location (stop position) on the pallet 10z (the tire T of the vehicle C1 is placed in a predetermined position), the door 31 is closed by the user or manager operating the operation panel. The direction in which the vehicle C1 enters the loading / unloading section 20 (pallet 10z) is along the longitudinal direction of the pallet 10z. In FIG. 9, the vehicle C1 enters from the left to the right of the page.

[0094] After the user stops the vehicle C1 at a predetermined position on the pallet 10z, the user gets off the vehicle C1 and exits the device 1.

[0095] The "predetermined location on the pallet 10" is a location where any of the ends of the front, rear, left, and right sides of the vehicle C fits within the space on the top surface of the pallet 10.

[0096] The "stop position" is the position on the top surface of the pallet 10 where the tire stoppers 17 (first swing plate 171 and second swing plate 173) are arranged.

[0097] Furthermore, when the vehicle is not in the designated location on the pallet (when at least one of the front, rear, left, or right ends of the vehicle protrudes from the space on the top surface of the pallet) or when the vehicle's tires are not in the parked position, the door will not close even when the control panel is operated.When the mechanical parking device detects that the vehicle is not in the designated location on the pallet, it will notify the driver that the vehicle is not in the designated location on the pallet by audio guidance from a speaker or by displaying on a display panel.

[0098] The "notice that the vehicle is not in the designated place on the pallet" is, for example, a notice to re-enter the pallet or a notice informing the user that the vehicle being stored is out of specification and cannot be stored. The fact that the vehicle is not in the designated place on the pallet is detected, for example, by a sensor (not shown) that detects vehicles protruding from the pallet and is arranged in the storage / retrieval section.

[0099] Next, after the door 31 is closed, the lift 40 lowers the pallet 10z on which the vehicle C1 is placed down the elevator shaft UD. At this time, the lift 40 first raises the pallet 10z to a position slightly above the opening 22h.

[0100] Next, the pallet support section 60 is retracted from the pallet support position to the retracted position by the drive device 80. At this time, the tilt prevention stopper 70 retracts together with the pallet support section 60 from the swing restriction position to the swing restriction release position.

[0101] After the pallet support part 60 and the tilt prevention stopper 70 have retreated to their respective positions, the lift 40 lowers the pallet 10z within the hoistway UD. The first swing plate 171 and the second swing plate 173 each swing as the restriction imposed by the tilt prevention stopper 70 is released. The swing range of the first swing plate 171 is restricted by the first swing adjustment plate 18, and the swing range of the second swing plate 173 is restricted by the second swing adjustment plate 19.

[0102] FIG. 10 is a schematic side view showing a state in which the restriction on the swinging of the wheel stopper 17 (first swinging plate 171, second swinging plate 173) is released. The figure shows a state in which the first swing plate 171 and the second swing plate 173 are both swinging rearward, and the movement of the tire T is restricted by the swing of the first swing plate 171.

[0103] When the vehicle C placed on the pallet 10z is a vehicle C1 with a long front overhang as in this embodiment, the stopping position of the tire T of the vehicle C1 is the rear side of the first rocking plate 171. Because the first rocking plate 171 rocks rearward, a portion of the tire T placed on the first rocking plate 171 falls into the opening 16h. As a result, a portion of the tire T falls into the opening 16h and is in two-point contact with the first rocking plate 171 and the pallet main body 11 in the front-rear direction. In addition, the front side of the first rocking plate 171 protrudes from the upper surface of the pallet main body 11. Therefore, movement of the tire T in the front-rear direction is restricted.

[0104] The pallet 10z descends down the elevator shaft UD as the lift 40 descends, and stops at the first storage floor B1 under the control of a control unit (not shown). The pallet 10z that has stopped at the first storage floor B1 is fed vertically or horizontally by the rotation of the drive roller 51a, and is transported to the adjacent second transport device 50b.

[0105] The second conveying device 50b conveys the pallet 10z vertically or horizontally to another adjacent second conveying device 50b by rotating the drive roller 51b. In this way, the device 1 stores the pallet 10 in a desired storage section (an empty space where no other pallets 10a-10i are placed). When the second conveying device 50b conveys the pallet 10z to a desired storage section, the other pallets 10a-10i placed on the second conveying device 50b are conveyed vertically or horizontally as appropriate. In other words, the device 1 stores the pallet 10z in a desired storage section by moving the pallet 10z and the other pallets 10a-10i placed on the second conveying device 50b like a puzzle.

[0106] When the vehicles C1 placed on the pallet 10z and the other vehicles C placed on the other pallets 10a-10i are transported vertically by the second transport device 50b, a portion of the tire T of each vehicle falls into the opening 16h and comes into contact with the first rocking plate 171 and the pallet body 11 at two points in the front-to-rear direction. In addition, the front side of the first rocking plate 171 protrudes from the upper surface of the pallet body 11. Therefore, movement of the tire T in the front-to-rear direction is restricted.

[0107] ●Removal operation The following description will be given of the retrieval operation by the device 1, taking as an example the case where a vehicle C placed on a pallet 10z stored in the storage section B16 is retrieved (the pallet 10z is not shown in FIG. 2). The retrieval operation is substantially the opposite of the retrieval operation. Therefore, a description of the retrieval operation that is common to the retrieval operation will be omitted.

[0108] First, when a user or manager of the vehicle C placed on the pallet 10z operates an operation panel (not shown), the device 1 calls the pallet 10z.

[0109] The pallet 10z is transported vertically or horizontally by the rotation of the drive roller 51b of the second transport device 50b placed in the storage section B16, and is transported to the first transport device 50a placed on the lift 40 in the elevator shaft UD. When the pallet 10z is transported from the second transport device 50b placed in the storage section B16 to the first transport device 50a, the pallets 10a-10i placed on each of the second transport devices 50b are transported vertically or horizontally as appropriate.

[0110] When the vehicles C1 placed on the pallet 10z and the other vehicles C placed on the other pallets 10a-10i are transported vertically by the second transport device 50b, a portion of the tire T of each vehicle falls into the opening 16h and comes into contact with the first rocking plate 171 and the pallet body 11 at two points in the front-to-rear direction. In addition, the front side of the first rocking plate 171 protrudes from the upper surface of the pallet body 11. Therefore, movement of the tire T in the front-to-rear direction is restricted.

[0111] After the pallet 10z is placed on the first conveying device 50a, the pallet 10z ascends up the elevator shaft UD by the lift 40. The lift 40 raises the pallet 10z slightly above the opening 22h. At this time, the pallet support part 60 is in the retracted position, and the tilt prevention stopper 70 is in the swing restriction release position.

[0112] Next, the pallet support part 60 advances from the retracted position to the pallet support position by the drive device 80. At this time, the tilt prevention stopper 70 advances together with the pallet support part 60 from the swing restriction release position to the swing restriction position.

[0113] After the pallet support parts 60 and the tilt prevention stoppers 70 have advanced to their respective positions, the lift 40 lowers the pallet 10z to the position of the opening 22h, and the pallet 10z is supported by the pallet support parts 60. At this time, the swinging of the first swinging plate 171 and the second swinging plate 173 is restricted (the swinging state is released) by the tilt prevention stoppers 70, and the top surface of the pallet main body 11 becomes flat.

[0114] The pallet 10z stops at the opening 22h of the loading / unloading section 20 under the control of the control unit, and in a state in which the pallet 10z supported by the pallet support section 60 stops at the opening 22h of the loading / unloading section 20, the vehicle C placed on the pallet 10z is positioned with the rear side of the vehicle C facing the door 31. The pallet 10z is rotated 180 degrees by the rotation of a swivel section (not shown), and the front side of the vehicle C is positioned facing the door 31.

[0115] Next, the door 31 opens, and the user gets into the vehicle C and drives it forward out of the loading / unloading section 20 (the device 1). After the vehicle C has left the parking lot, the door 31 closes by the user or the caretaker operating the control panel.

[0116] In this way, the pallet 10z is flat in the loading / unloading section 20, with the swinging of the first swing plate 171 and the second swing plate 173 restricted by the tilt prevention stopper 70. On the other hand, when the pallet 10z is moving from the loading / unloading section 20 (when it is moving up and down the elevator shaft UD, or when it is being fed vertically or horizontally in the storage space SP), the restriction by the tilt prevention stopper 70 is released, and the first swing plate 171 and the second swing plate 173 become swingable.

[0117] ●Summary● According to the embodiment described above, the device 1 includes the anti-tilt stopper 70. The pallet 10 included in the device 1 includes the tire stopper 17. The tire stopper 17 includes a first rocking plate 171 and a second rocking plate 173. In the loading / unloading section 20, the first stopper portion 72, second stopper portion 73, and third stopper portion 74 of the anti-tilt stopper 70 restrict the rocking of the first rocking plate 171 and the second rocking plate 173, thereby making the pallet 10 flat. A vehicle C entering through the loading / unloading entrance 30 can travel on the flat upper surface (surface) of the pallet 10, without having to travel on an uneven pallet like a conventional tire stopper. This makes the pallet 10 barrier-free, facilitating entry of vehicles C onto the pallet 10.

[0118] On the other hand, when the pallet 10 is moving from the loading / unloading section 20 (when it is moving up and down the elevator shaft UD, or when it is being fed vertically or horizontally through the storage space SP), the restriction by the first stopper portion 72, the second stopper portion 73, and the third stopper portion 74 of the tilt prevention stopper 70 is released, and the first rocking plate 171 and the second rocking plate 173 become able to rock. The first rocking plate 171 rocks rearward, and the rocking range of the first rocking plate 171 is restricted by the first rocking adjustment plate 18. The second rocking plate 173 rocks rearward, and the rocking range of the second rocking plate 173 is restricted by the second rocking adjustment plate 19. Due to the rocking of the first rocking plate 171, some of the tires T of the vehicle C placed on the first rocking plate 171 in the loading / unloading section 20 fall into the opening 16h. As a result, a part of the tire T falls into the opening 16h and comes into contact with the first rocking plate 171 and the pallet body 11 at two points in the front-rear direction. In addition, the front side of the first rocking plate 171 protrudes from the upper surface of the pallet body 11. Therefore, movement of the tire T in the front-rear direction is restricted. As a result, it is possible to prevent the vehicle C from falling off the pallet 10.

[0119] In the embodiment described above, an example has been described in which a vehicle C1 with a long front overhang is placed on the pallet 10. However, when a vehicle C2 with a short front overhang is placed on the pallet 10, the position at which the tire T is placed is different from when the vehicle C1 is placed on the pallet 10.

[0120] FIG. 11 is a schematic side view showing another state in which the restriction on the swinging of the wheel stopper 17 (first swinging plate 171, second swinging plate 173) is released.

[0121] The figure shows that the tire T of the vehicle C2 is placed across the first rocking plate 171 and the second rocking plate 173. The figure also shows a state in which the first rocking plate 171 rocks forward and the second rocking plate 173 rocks rearward, and the movement of the tire T is restricted by the rocking of the first rocking plate 171 and the rocking of the second rocking plate 173.

[0122] Moreover, the pallet 10 shown in the figure has the same configuration as the pallet 10 in the embodiment previously described.

[0123] When the pallet 10 is moving from the loading / unloading section 20 (when it is moving up and down the elevator shaft UD, or when it is being fed vertically or horizontally through the storage space SP), the restriction by the first stopper portion 72, the second stopper portion 73, and the third stopper portion 74 of the tilt prevention stopper 70 is released, and the first rocking plate 171 and the second rocking plate 173 become able to rock. The first rocking plate 171 rocks forward, and the rocking range of the first rocking plate 171 is restricted by the second rocking adjustment plate 19. The second rocking plate 173 rocks backward, and the rocking range of the second rocking plate 173 is restricted by the second rocking adjustment plate 19.

[0124] Due to the swinging of the first rocking plate 171 and the second rocking plate 173, a portion of the tire T of the vehicle C2, which has been placed across the first rocking plate 171 and the second rocking plate 173 in the loading / unloading section 20, falls into the opening 16h. As a result, the portion of the tire T falls into the opening 16h and comes into contact with the first rocking plate 171 and the second rocking plate 173 at two points in the front-to-rear direction. Therefore, movement of the tire T in the front-to-rear direction is restricted. As a result, the vehicle C can be prevented from falling off the pallet 10.

[0125] The position where the tire stopper is placed is not limited to the right side of the front side of the pallet body. That is, for example, the tire stopper may be placed on the left side of the front side of the pallet body or on both the left and right sides of the front side.

[0126] The tire stoppers may also be arranged on both the left and right sides of the rear side of the pallet body, or on either the left or right side of the rear side.

[0127] Furthermore, the tire stops may be arranged on both the front and rear of the pallet body, on either the left or right side, or on both the left and right sides.

[0128] When tire stops are disposed at positions other than the right front side of the pallet body, the openings may be configured to correspond to the positions where each tire stop is disposed. In this case, an anti-tilt stopper corresponding to each tire stop is disposed at the tip of the pallet support part.

[0129] Furthermore, the second rocking plate may be a seesaw-shaped rocking plate similar to the first rocking plate.

[0130] Furthermore, the tire stopper may be provided with a seesaw-shaped rocking plate similar to the first rocking plate, or a cantilever-shaped rocking plate similar to the second rocking plate, or both, behind the first rocking plate.

[0131] Furthermore, in the embodiment described above, in the loading / unloading section 20, the swinging of the first rocking plate 171 and the second rocking plate 173 was restricted by the first stopper portion 72, the second stopper portion 73, and the third stopper portion 74 of the tilt prevention stopper 70. However, in the loading / unloading section, the force that tends to cause the first rocking plate and the second rocking plate to swing (the load acting on the first rocking plate and the second rocking plate) increases due to the weight of the vehicle. In order to more reliably restrict the swinging of the first rocking plate and the second rocking plate, the mechanical parking device may be provided with an auxiliary member. The auxiliary member is attached to the lift or the first transport device. The auxiliary member supports the tilt prevention stopper from below and reinforces the force restricting the swinging.
