Description

[Technical Field]

[0001] The present invention relates to a parking system for parking a vehicle such as an automobile. [Background technology]

[0002] A known vehicle parking system is a multi-level parking system in which multiple pallets on which vehicles can be placed are stacked to park multiple vehicles. When a user wants to enter or exit a vehicle in a multi-level parking system, the user operates a control panel to move the pallets up and down or sideways, and the desired pallet is called up to the entrance or exit.

[0003] As disclosed in Patent Document 1, for example, a multi-level parking system includes a lifting guide that engages with a guide rail that is attached to a support and extends in the vertical direction, in order to stabilize the lifting and lowering movement of the pallet. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-209644 Summary of the Invention [Problem to be solved by the invention]

[0005] However, because the parking system also allows pallets to move laterally, the guide rails must be spaced apart to allow the lift guide to move laterally. As a result, there are areas without guide rails, and when a pallet on an upper level moves up or down, the tip of the lift guide leaves the end of one guide rail, passes through the area without a guide rail, and enters the start of the other guide rail.

[0006] If the parking system is operated incorrectly during a typhoon or other strong wind, the pallet may be blown around by the strong wind. When the pallet is blown around by the strong wind, in areas without guide rails, the tip of the lifting guide cannot properly enter the beginning of the guide rail, and there is a risk that it may come off the guide rail. If there is no vehicle on the pallet, it is lighter in weight and particularly susceptible to being blown around.

[0007] Therefore, an object of the present invention is to provide a parking system that can ensure safety even when operating in the event of strong winds such as a typhoon. [Means for solving the problem]

[0008] A parking system according to one embodiment of the present invention comprises a pallet for placing a vehicle on it, a lifting guide attached to the pallet and linked to the pallet, a plurality of guide rails arranged vertically at intervals, a lifting device that moves the pallet vertically so that the lifting guide follows the guide rails, an anemometer that measures the surrounding wind speed, and a control unit that, when it determines that the wind speed is equal to or greater than a first wind speed, controls the lifting device so that a first movement speed of the pallet when a portion of the lifting guide is located in the interval is slower than a second movement speed of the pallet when the entire lifting guide is located on the guide rail.

[0009] With this configuration, even if the parking system is operated during a strong wind such as a typhoon, if the wind speed around the parking system exceeds the first wind speed, the lifting / lowering speed of the pallet when part of the lifting / lowering guide is positioned between the guide rails (first movement speed) is controlled to be slower than when the entire lifting / lowering guide is positioned on the guide rails. Therefore, even if the lifting / lowering guide is about to come off the guide rails or has come off the guide rails, the user can immediately perform an emergency stop on the parking system, ensuring safety. If the lifting / lowering guide is not about to come off the guide rails, the pallet can continue to move up and down as is.

[0010] A parking system according to one embodiment of the present invention further includes a traverse carriage connected to the pallet, and a traverse device that moves the traverse carriage laterally, wherein the plurality of guide rails include a plurality of first guide rails fixed to pillars and a second guide rail that is linked to the traverse carriage and is located between adjacent first guide rails, and when the traverse device moves the traverse carriage in the lateral direction, all of the lifting guides may be located between adjacent first guide rails, and part of the lifting guides may be engaged with the second guide rails.

[0011] In a parking system according to one embodiment of the present invention, when the control unit determines that the wind speed is equal to or greater than the first wind speed, the control unit may control the lifting device to make the first movement speed slower than the first movement speed when the wind speed is less than the first wind speed.

[0012] In the parking system according to one embodiment of the present invention, when the control unit determines that the wind speed is equal to or higher than the first wind speed, the control unit may output a predetermined first display to the display unit.

[0013] A parking system according to one embodiment of the present invention further includes an operation unit that accepts user operations, and the control unit may stop the movement of the pallet when it determines that the wind speed is equal to or greater than a second wind speed that is greater than the first wind speed while the pallet is being moved.

[0014] In a parking system according to one embodiment of the present invention, after the control unit determines that the wind speed is equal to or greater than the second wind speed, the control unit may maintain the pallet stopped regardless of operation on the operating unit.

[0015] In a parking system according to one embodiment of the present invention, when the control unit determines that the wind speed is equal to or greater than a second wind speed but less than a third wind speed, the control unit may maintain the pallet stopped regardless of operation on the operating unit until a predetermined time has elapsed at which the wind speed is equal to or less than a fourth wind speed that is lower than the second wind speed, and when the determined wind speed is equal to or greater than the third wind speed, the control unit may maintain the pallet stopped regardless of operation on the operating unit.

[0016] In the parking system according to one embodiment of the present invention, when the control unit determines that the wind speed is equal to or higher than the second wind speed, the control unit may cause the display unit to output a predetermined second display.

[0017] A parking system according to one embodiment of the present invention further includes an operation unit that accepts user operation, and when the user operates the control unit, if the control unit determines that the wind speed is equal to or greater than a second wind speed that is greater than the first wind speed and the pallet is not being moved, the control unit may maintain the pallet stopped regardless of the operation of the operation unit.

[0018] A parking system according to one embodiment of the present invention further includes an operation unit that accepts user operation, and when the control unit determines that the wind speed is equal to or greater than a second wind speed that is greater than the first wind speed when the pallet is not being moved during user operation, the control unit may, when the determined wind speed is equal to or greater than the second wind speed but less than a third wind speed, maintain the pallet stopped regardless of operation on the operation unit until the wind speed becomes equal to or less than a fourth wind speed that is smaller than the second wind speed, and when the determined wind speed is equal to or greater than the third wind speed, maintain the pallet stopped regardless of operation on the operation unit until the wind speed remains equal to or less than the fourth wind speed for a predetermined time.

[0019] A parking system according to one embodiment of the present invention further includes a traverse carriage connected to the pallet, and a traverse device that moves the traverse carriage laterally, and when the traverse device moves the traverse carriage laterally, all of the lifting guides may be positioned within the interval. [Effects of the Invention]

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. To clarify the description, the drawings may show the width, thickness, shape, etc. of each part more schematically than the actual embodiment, but these are merely examples and are not intended to limit the interpretation of the present invention. In this specification and each drawing, elements similar to those previously described with reference to the previous drawings are designated by the same reference numerals, and detailed descriptions may be omitted as appropriate.

[0023] <Parking system configuration> A parking system according to one embodiment of the present invention will be described below. Fig. 1 is a front view showing an outline of the parking system 1. Fig. 2 is a side view showing an outline of the parking system 1.

[0024] As shown in Figures 1 and 2, the parking system 1 has a framework formed by a plurality of support columns 500 erected on the ground and extending in the vertical direction, and a plurality of beams 600 (not shown in Figure 2) erected on the support columns 500 and extending in the horizontal direction. An entrance / exit gate for vehicles 700 to enter and exit the parking system is formed on the ground, and a gate 60 is installed to prohibit unauthorized entry. In this specification, the side of the parking system 1 with the gate 60 thereon is referred to as the front, and the opposite side is referred to as the back. The left and right directions will be described based on facing the front of the parking system 1.

[0025] (Parking area) As shown in Fig. 1, the parking system 1 can partition a total of 16 parking areas A, with four rows in the vertical direction and four rows in the horizontal direction. The number of parking areas A is not limited to this. In this specification, rows are counted from the ground as the first row, second row, third row, fourth row, and so on, and rows are counted from the left end as the first row, second row, third row, fourth row, and so on.

[0026] In the parking system 1, vehicles 700 parked in parking areas A other than the first level (second to fourth levels) must move up and down (hereinafter referred to as "lifting and lowering movement") between the parking areas A and the ground. When attempting to lift and lower a vehicle 700 parked in the top level (fourth level) of parking area A, the pallets 10 other than the top level (first to third levels) in that row must move to either the left or right (hereinafter referred to as "lateral movement"). When lateral movement is taken into account, a maximum of 13 vehicles 700 can actually be parked in 16 parking areas A, as shown in FIG. 1.

[0027] As shown in FIGS. 1 and 2, the parking system 1 includes a pallet 10, a lifting device 20, a traversing cart 30, a traversing device 40, an anemometer 50, a gate 60, and an operation panel 70.

[0028] (palette) The pallets 10 have a rectangular shape in a plan view so that vehicles 700 can be placed thereon, but the shape is not limited to this. In Fig. 1, a total of 13 pallets 10 are arranged, but the number of pallets 10 is not limited to this and may be arranged according to the number of vehicles 700 to be parked.

[0029] The pallets 10 include a lower pallet 10 arranged in the first parking area A, which is the lowest level, an upper pallet 10 arranged in the fourth parking area A, which is the highest level, and a middle pallet 10 arranged in the second and third parking areas A other than the lowest and top levels.

[0030] (Traveling cart, traveling device and lifting device) The lower pallet 10 does not need to move up and down, but does need to move laterally. For this reason, the lower pallet 10 is not connected to the lifting device 20, but is connected to a lateral movement device (not shown). The lateral movement device includes rails extending in the left-right direction, a plurality of wheels attached to the lower pallet 10 that engage with the rails, and a drive unit that drives the wheels. By driving the drive unit of the lateral movement device, the lower pallet 10 can be moved laterally.

[0031] The middle pallet 10 needs to move both laterally and vertically. For this reason, the middle pallet 10 is connected to the traverse carriage 30 via a lifting device 20. The traverse carriage 30 surrounds the vehicle 700 and has a square-shaped configuration in a plan view, but the shape is not limited to this. The lifting device 20 is installed on the traverse carriage 30. The lifting device 20 includes a hoisting chain 22 that suspends and supports the middle pallet 10, and a drive unit 21 that is installed on the traverse carriage 30 and reels in and out the hoisting chain 22. The drive unit 21 drives to reel in the hoisting chain 22, thereby lowering the pallet 10 to the ground, and the drive unit 21 drives to reel in the hoisting chain 22, thereby raising the middle pallet 10 from the ground to the traverse carriage 30. The traverse carriage 30 is also connected to a traverse device 40. The traverse device 40 is installed on the beam 600 and includes rails extending in the left-right direction, a plurality of wheels attached to the traverse carriage 30 and engaging with the rails, and a drive unit that drives the wheels. By driving the drive unit of the traverse device 40, the traverse carriage 30 can be moved laterally, and therefore the middle pallet 10 can also be moved laterally.

[0032] The upper pallet 10 does not need to move laterally, but does need to move up and down. For this reason, the upper pallet 10 is not connected to the lateral travelling cart 30, but is connected to the lifting device 20. The lifting device 20 includes a suspending chain 22 that suspends and supports the upper pallet 10, and a drive unit 21 that is installed on the beam 600 and that reels out and takes up the suspending chain 22. By driving the drive unit 21 of the lifting device 20, the upper pallet 10 can be moved up and down between the ground.

[0033] As shown in Figures 1 and 2, the parking system 1 is equipped with an elevation guide 31 that moves in conjunction with the elevation movement of the pallet 10 to stabilize the elevation movement of the pallet 10, and a plurality of guide rails 32 that extend in the vertical direction and are arranged along the vertical direction.

[0034] Fig. 3 is a front view showing an outline of the relationship between the lift guide 31 and the guide rail 32 at the boundaries of the parking areas A of the first row of the second tier, the second row of the second tier, the first row of the third tier, and the second row of the third tier in Fig. 1. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3. Fig. 5 is a cross-sectional view taken along line VV in Fig. 3. The boundaries of the parking areas A of the second and third tiers have a similar structure.

[0035] (Lifting guide) As shown in Figures 1, 3, and 4, the lifting guides 31 include a right lifting guide 31R located on the right side of the pallet 10 and a left lifting guide 31L located on the left side of the pallet 10. The lifting guides 31 are made of plate-like members, but the shape is not limited to this as long as they can engage with the guide rails 32. The right lifting guide 31R is fixed to the right end of the rear side of the pallet 10, and the left lifting guide 31L is fixed to the left end of the rear side of the pallet 10 via connecting members (not shown). In Figures 3 and 4, the right lifting guide 31R is fixed to the right end of the rear side of the first pallet 10 in the third tier, and the left lifting guide 31L is fixed to the left end of the rear side of the second pallet 10 in the third tier.

[0036] (guide rail) As shown in FIGS. 1 and 3 , the guide rails 32 include a first guide rail 321 fixed to the support 500 and a second guide rail 322 fixed to the transverse carriage 30 and moving in conjunction with the transverse carriage 30. The first guide rail 321 includes a right-side first guide rail 321R that engages with the right-side lift guide 31R and a left-side first guide rail 321L that engages with the left-side lift guide 31L. The second guide rails 322 include a lower second guide rail 322D installed on the right side of the transverse carriage 30 and an upper second guide rail 322U installed on the left side of the transverse carriage 30. In FIGS. 3 and 4 , the upper second guide rail 322U is installed on the left side of the second transverse carriage 30 of the third tier. In FIG. 3 , the lower second guide rail 322D is installed on the right side of the first transverse carriage 30 of the third tier.

[0037] As shown in Fig. 3, the first guide rails 321R, 321L are made up of members that extend in the vertical direction. Also, as shown in Fig. 5, the right-side first guide rail 321R has a U-shape that opens to the left in a cross-sectional view, and the left-side first guide rail 321L has a U-shape that opens to the right in a cross-sectional view. The shapes of the first guide rails 321R, 321L are not limited to these, as long as they can engage with the lift guides 31R, 31L.

[0038] As shown in Fig. 3, the second guide rails 322U and 322D are configured by connecting two members extending in the vertical direction. Furthermore, as shown in Fig. 4, the upper second guide rail 322U is configured, in cross section, by a U-shaped member opening on the left side, a U-shaped member opening on the right side, and a plate-shaped connecting member connecting these. The shape of the upper second guide rail 322U is not limited to this, as long as it can engage with the lift guide 31. The lower second guide rail 322D has a configuration similar to that of the upper second guide rail 322U.

[0039] As shown in FIG. 3, the first guide rails 321 are spaced apart in the vertical direction to allow the lift guides 31R and 31L to move laterally. The vertical size of the lift guides 31R and 31L is smaller than the distance between the first guide rails 321R and 321L. The vertical sizes of the upper second guide rail 322U and the lower second guide rail 322D are each smaller than the vertical size of the lift guides 31R and 31L. The upper second guide rail 322U and the lower second guide rail 322D complement the distance between the first guide rails 321R and 321L. When the pallet 10 moves laterally, all of the lift guides 31R and 31L are positioned in the space between the adjacent first guide rails 321R and 321L, and portions of the lift guides 31R and 31L are engaged with the second guide rails 322U and 322D.

[0040] Figure 6 is a diagram showing an outline of the positional relationship between the lifting and lowering guides 31R, 31L and the guide rail 32 when the second pallet 10 in the third tier in Figure 3 is moved laterally to the third tier, third parking area A. As shown in Figure 6, when the second pallet 10 in the third tier is moved to the right, the left lifting and lowering guide 31L of the second pallet 10 in the third tier moves to the right while engaging with the upper second guide rail 322U.

[0041] Figure 7 is a diagram showing an outline of the positional relationship between the lift guide 31 and the guide rails 32 when the second pallet in the third tier in Figure 3 is moved laterally to the third tier parking area A. As shown in Figure 7, an area NL without guide rails 32 exists between the left first guide rail 321L and the lower second guide rail 322D in the second tier. Also, an area NR without guide rails 32 exists between the upper second guide rail 322U in the second tier in the third tier and the right guide rail 321R in the second tier in the second tier. Similarly, areas NL and NR without guide rails 32 exist at the boundary between the second and third tier parking areas A.

[0042] 8 and 9 are schematic diagrams illustrating the positional relationship between the lift guide 31 and the guide rail 32 when the upper pallet 10 in the second row of the fourth row in FIG. 7 (in the parking area A for the second row of the third row) is being lowered to the ground. As shown in FIG. 8, the left lift guide 31L of the second row of the fourth row pallet 10 leaves the end of the left first guide rail 321L, passes through the area NL where no guide rail 32 is present, and enters the start of the lower second guide rail 322D. At the same time, as shown in FIG. 9, the right lift guide 31R of the second row of the fourth row pallet 10 leaves the end of the right first guide rail 321R and immediately enters the upper second guide rail 322U. Then, it leaves the end of the second guide rail 322U, passes through the area NR where no guide rail 32 is present, and enters the start of the right first guide rail 321R. When strong winds occur due to a typhoon or the like, if the pallet 10 is blown by the strong wind in the areas NL and NR where there are no guide rails 32, the lifting guide 31 may not properly enter the starting end of the guide rail 32, and the lifting guide 31 may come off the guide rail 32.

[0043] (anemometer) 1 and 2, the parking system 1 includes an anemometer 50. The anemometer 50 is installed on the top shelf, but the installation location is not limited to this.

[0044] 1 and 2, the parking system 1 includes an operation panel 70. The operation panel 70 is installed near the gate 60, but the installation location is not limited to this. As shown in FIG. 10, the operation panel 70 includes a control unit 71, a display unit 72, an operation unit 73, and a memory unit 74. The control unit 71 and the memory unit 74 may be separated from the operation panel 70, so that the operation panel 70 includes the display unit 72 and the operation unit 73, and the control panel includes the control unit 71 and the memory unit 74.

[0045] The display unit 72 displays the status of the parking system 1. The operation unit 73 inputs user commands such as calling the pallet 10, opening / closing the gate 60, and emergency stopping of the pallet 10. The memory unit 74 stores a control program in which control methods for the lifting device 20, the traversing device 40, the anemometer 50, and the gate 60 are set. The memory unit 74 can also store data measured by the anemometer 50.

[0046] (Control unit) 11, the control unit 71 is communicatively connected to the lifting device 20, the traversing device 40, the anemometer 50, and the gate 60. Based on a control program stored in a memory unit 74, the control unit 71 controls the lifting device 20, the traversing device 40, the anemometer 50, and the gate 60 in accordance with user commands input through an operation unit 73. The control unit 71 also receives wind speed data measured by the anemometer 50.

[0047] In the control program, the control unit 71 is set so as to cause the traverse carriage 30 to move laterally at a predetermined speed.

[0048] When the control unit 71 determines that the wind speed measured by the anemometer 50 is less than the first wind speed, that is, during normal operation, the ascending and descending movement of the pallet 10 is set, for example, to accelerate toward a maximum speed of 90 mm / s during ascending and descending (if the maximum speed is exceeded, the speed is decelerated toward the maximum speed; similarly below), and to accelerate toward a maximum speed of 120 mm / s during descending. The first wind speed is set, for example, to 8 m / s.

[0049] When the control unit 71 determines that the wind speed measured by the anemometer 50 is equal to or greater than the first wind speed, the first movement speed, which is the speed of the ascending and descending movement of the pallet 10 when a portion of the lift guide 31 is located in the area NL, NR where there are no guide rails 32, is set to be slower than the second movement speed, which is the speed of the ascending and descending movement of the pallet 10 when the entire lift guide 31 is located in the area where there are guide rails 32. For example, the first movement speed is set to a speed that accelerates toward a maximum speed of 60 mm / s during ascending and descending, and a speed that accelerates toward a maximum speed of 50 mm / s during descending. The second movement speed is set to a speed that accelerates toward a maximum speed of 90 mm / s, preferably 70 mm / s, during ascending and descending, and a speed that accelerates toward a maximum speed of 120 mm / s, preferably 70 mm / s, during descending. Furthermore, the first movement speed when it is determined that the wind speed measured by the anemometer 50 is equal to or greater than the first wind speed can be set to be slower than the first movement speed when it is determined that the wind speed is less than the first wind speed.

[0050] When the control unit 71 determines that the wind speed measured by the anemometer 50 is equal to or greater than the first wind speed, the control unit 71 causes the display unit 72 to output a predetermined first display, such as by turning on a yellow lamp on the indicator light.

[0051] When the control unit 71 determines that the wind speed measured by the anemometer 50 is equal to or greater than a second wind speed that is greater than the first wind speed while the pallet 10 is being moved, the control unit 71 stops the movement of the pallet 10. In this case, the control unit 71 causes the display unit 72 to output a predetermined second display, such as by turning on a red lamp on the indicator light. The second wind speed is set to, for example, 10 m / s.

[0052] If the control unit 71 determines that the wind speed measured by the anemometer 50 is equal to or greater than the second wind speed and less than the third wind speed, the control unit 71 maintains the stoppage of the movement of the pallet 10 until the wind speed reaches or falls below a fourth wind speed, which is slower than the second wind speed, for a predetermined time, regardless of the operation of the operation unit 73. Once the predetermined time has passed at or below the fourth wind speed, the stoppage of the pallet 10 is released, and the pallet 10 can be moved again by operating the operation unit 73. If the control unit 71 determines that the wind speed is equal to or greater than the third wind speed, the stoppage of the pallet 10 is maintained regardless of the operation of the operation unit 73. In this case, the control unit 71 cannot release the stoppage of the pallet 10. The third wind speed is set to, for example, 15 m / s. The fourth wind speed is set to, for example, less than the second wind speed, preferably less than the first wind speed. The predetermined time is set to, for example, 300 s.

[0053] If the control unit 71 determines that the pallet 10 is not moving and the wind speed measured by the anemometer 50 is equal to or greater than a second wind speed that is greater than the first wind speed, the control unit 71 maintains the stoppage of the movement of the pallet 10 regardless of the user's operation on the operation unit 73.

[0054] If the control unit 71 determines that the wind speed measured by the anemometer 50 is equal to or greater than the second wind speed and less than the third wind speed, the stop of the movement of the pallet 10 is maintained regardless of operation by the operation unit 73 until the wind speed becomes equal to or less than a fourth wind speed that is slower than the second wind speed. Once the wind speed becomes equal to or less than the fourth wind speed, the stop of the pallet 10 is released, and the pallet 10 can be moved by operation by the operation unit 73. If the control unit 71 determines that the wind speed is equal to or greater than the third wind speed, the stop of the movement of the pallet 10 is maintained regardless of operation by the operation unit 73 until a predetermined time has passed at a fourth wind speed that is lower than the second wind speed and less than the fourth wind speed. Once the predetermined time has passed at a fourth wind speed and less than the fourth wind speed, the stop of the pallet 10 is released, and the pallet 10 can be moved by operation by the operation unit 73.

[0055] <Parking system operation> Next, the operation of the parking system according to one embodiment of the present invention will be described. Fig. 12 is a flow diagram of the parking system 1 when the power of the parking system 1 is turned on. Fig. 13 is a flow diagram of the parking system 1 when the control unit 71 is moving the pallet 10. It is assumed that wind speed is measured by the anemometer 50 at all times.

[0056] First, a flow of the parking system 1 when the parking system 1 is powered on will be described. In Fig. 12, the user operates the operation unit 73 to power on the parking system 1 (S210). When the parking system 1 is powered on, the control unit 71 determines the wind speed (S220).

[0057] If the control unit 71 determines that the wind speed is less than the first wind speed of 8 m / s (No in S221), the control unit 71 accepts input from the user via the operation unit 73. This allows the user to input commands by operating the operation unit 73 to perform operations such as calling up the pallet 10 (S230). If the control unit 71 determines that the wind speed is equal to or greater than 8 m / s and less than the second wind speed of 10 m / s (Yes in S221, No in S222), the control unit 71 limits the first movement speed of the up-and-down movement of the pallet 10 when a part of the lift-and-low guide 31 is located in the areas NL and NR where there are no guide rails 32 to a speed that accelerates toward a maximum speed of 60 mm / s during lift-up and a speed that accelerates toward a maximum speed of 50 mm / s during descent (S240). Furthermore, the second movement speed of the pallet 10 in the region where the entire lift guide 31 is on the guide rail 32 is set to a speed that accelerates toward a maximum speed of 90 mm / s when lifting and a speed that accelerates toward 120 mm / s when lowering. Furthermore, the control unit 71 turns on a yellow lamp among the indicator lights on the operation panel 70. Then, the control unit 71 accepts input from the user via the operation unit 73 (S230).

[0058] In step S220, if the control unit 71 determines that the wind speed is equal to or greater than 10 m / s and less than the third wind speed of 15 m / s (No in S223), the control unit 71 rejects input from the user via the operation unit 73 (S250). Thereafter, the control unit 71 again determines the wind speed measured by the anemometer 50 (S260). If the wind speed determined by the control unit 71 is less than the fourth wind speed of 5 m / s (Yes in S260), the control unit 71 accepts input from the user via the operation unit 73 (S230). If the wind speed is not less than 5 m / s (No in S260), the control unit 71 continues to reject input from the user via the operation unit 73 (S250).

[0059] In step S220, if the control unit 71 determines that the wind speed is 15 m / s or higher (if Yes in S223), the control unit 71 rejects input from the user via the operation unit 73 (S270). Furthermore, the control unit 71 turns on the red lamp of the indicator light on the operation panel 70. Thereafter, the control unit 71 again determines the wind speed measured by the anemometer 50 (S280). If the wind speed determined by the control unit 71 is less than 5 m / s and a predetermined time of 300 seconds has elapsed (if Yes in S280), the control unit 71 accepts input from the user via the operation unit 73 (S230). If the wind speed is less than 5 m / s and the predetermined time has not elapsed (if No in S280), the control unit 71 continues to reject input from the user via the operation unit 73 (S270).

[0060] Next, the flow of the parking system 1 when the control unit 71 is moving the pallet 10 will be described. In Fig. 13, the control unit 71 receives input from the user via the operation unit 73 and moves the pallet 10 (S290). Thereafter, the control unit 71 determines the wind speed measured by the anemometer 50 (S300). Note that if the desired pallet 10 has arrived on the ground before the control unit 71 again determines the wind speed measured by the anemometer 50, the flow ends.

[0061] In step S300, if the control unit 71 determines that the wind speed is less than 8 m / s (No in S301), the control unit 71 determines whether the first movement speed is limited (S310). If the first movement speed is limited (Yes in S310), the control unit 71 cancels the limit on the first movement speed (S320) and moves the pallet 10 (S290). If the first movement speed is not limited (No in S310), the control unit 71 moves the pallet 10 as is (S290). If the control unit 71 determines that the wind speed is equal to or greater than 8 m / s and less than 10 m / s (Yes in S301, No in S302), the control unit 71 limits the first movement speed of the pallet 10 to a speed that accelerates toward a maximum speed of 60 mm / s when ascending or descending, and a speed that accelerates toward a maximum speed of 50 mm / s when descending, and limits the second movement speed to a speed that accelerates toward a maximum speed of 90 mm / s when ascending or descending, and a speed that accelerates toward a maximum speed of 120 mm / s when descending (S330).Then, the control unit 71 moves the pallet 10 (S290).

[0062] In step S300, if the control unit 71 determines that the wind speed is equal to or greater than 10 m / s and less than 15 m / s (Yes in S302, No in S303), the control unit 71 stops the movement of the pallet 10 (S340). The pallet 10 remains stationary regardless of the user's operation on the operation unit 73 (S350). The control unit 71 then again determines the wind speed measured by the anemometer 50 (S360). If the wind speed determined by the control unit 71 is less than 5 m / s and a predetermined time of 300 seconds has elapsed (Yes in S360), the control unit 71 accepts input from the user's operation unit 73 (S370). If the wind speed is less than 5 m / s and the predetermined time has not elapsed (No in S360), the control unit 71 maintains the pallet 10 stationary regardless of the user's operation on the operation unit 73 (S350).

[0063] In step S300, if the control unit 71 determines that the wind speed is 15 m / s or more (Yes in S303), the control unit 71 stops the movement of the pallet 10 (S380). Then, regardless of the user's operation on the operation unit 73, the control unit 71 maintains the pallet 10 stopped (S390). In this case, the control unit 71 does not release the pallet 10 from being stopped, and the user cannot call the pallet 10.

[0064] <Modification> Although the parking system according to one embodiment of the present invention has been described above, the present invention is not limited to this. For example, in the parking system 1, even if the wind speed determined by the control unit 71 is equal to or greater than the second wind speed, if it is less than the third wind speed, the control unit 71 can release the maintenance of the stopped pallet 10. However, if the wind speed becomes equal to or greater than the second wind speed, the control unit 71 can prevent the maintenance of the stopped pallet 10 from being released.

[0065] Furthermore, in the parking system 1, the second guide rails 322 are installed on the traverse carriage 30, but the traverse carriage 30 may be configured not to have the second guide rails 322. In this case, the intervals between adjacent first guide rails 321 become areas NL and NR where no guide rails 32 are installed.

[0066] The present embodiment has been described above, but other effects and advantages brought about by the aspects described in the present embodiment that are clear from the description in this specification or that can be appropriately conceived by a person skilled in the art are naturally understood to be brought about by the present invention.
