Description

  The present invention relates to a vertical circulation parking facility configured to accommodate a plurality of vehicles and circulate in a vertical direction, and a driving method thereof.

  Conventionally, as a parking facility provided on a limited area, a vertical circulation parking facility (hereinafter also simply referred to as “parking facility”) that circulates a plurality of cages vertically in a parking tower (tower) is known. ing.

  An example of this vertical circulation parking facility is shown in the front view of FIG. 5 (see, for example, Patent Document 1). In the following description, it is referred to as the right side and the left side when facing the front of the vertical circulation parking facility 51.

  As shown in FIG. 5, the vertical circulation parking facility 51 is provided with an upper sprocket 55 and a lower sprocket 56 at positions spaced apart from each other inside the parking tower 52, and the upper sprocket 55 and the lower sprocket 56 are separated from each other. A main chain 57 is wound around. The main chain 57 is provided with attachment links 58 for each predetermined pitch, and a cage 60 on which the vehicle V is mounted is suspended from these attachment links 58.

  Then, the upper sprocket 55 is rotated by a drive motor 66 provided on the upper frame of the parking tower 52, whereby the main chain 57 is rotated, and a cage group 62 consisting of the plurality of cages 60 (this specification and In the claims, a plurality of circulating cages are called “cage groups”). The circulation operation of the cage group 62 moves in an arc shape in the upper and lower parts of the parking tower 52 and moves in a straight line in the vertical portion at the left and right positions. The cage 60 is stopped at the entrance 70 located at the lowermost part of the parking tower 52, and the vehicle V is loaded or unloaded on the pallet 61 of the cage 60. The boarding unit 70 is provided with a sensor 71 that detects the vehicle V.

Japanese Patent No. 2549872

  By the way, in the vertical circulation parking facility 51, when the vehicle V is circulated while being accommodated in the cage 60, the load balance at the left and right positions of the cage group 62 (the difference in the total weight of the accommodated vehicles, (Also called) changes. Therefore, when the load on one of the left and right positions increases due to the circulation operation, the torque for raising the large load side to cause the circulation operation increases, and the load torque of the drive motor 66 also increases accordingly. This becomes larger as the load balance at the left and right positions becomes worse, and the load for circulating the cage group 62 becomes larger. In addition, at the time of starting to circulate the large load side in the winding direction, a load in the reverse direction is abruptly applied to the drive motor 66 by releasing the brake. Further, the load of the drive motor becomes maximum when the acceleration and speed are large during acceleration during the circulation operation.

  Therefore, the capacity of the drive motor 66 is a large drive output that can be rotated against the load, and can be accelerated even by rotation in the winding direction when the load unbalance amount at the left and right positions of the cage group 62 is maximum. It is preferable to select such that

  However, when such a drive motor 66 is selected, it is necessary to make the drive equipment and power supply equipment including the drive motor 66 large. Therefore, a large amount of cost is required for the drive equipment such as the drive motor 66 and the equipment constituting the power supply facility. Moreover, in order to increase the power supply capacity by increasing the power supply equipment, it is necessary to increase the contract power supply capacity of the parking equipment, which requires a lot of running costs.

  On the other hand, in the vertical circulation parking facility, since the entry and exit of the vehicle V are generally performed arbitrarily, the probability that the cage 60 accommodating the vehicle V in one of the left and right positions is very low. Therefore, in order to reduce the cost of the drive motor 66 and the like, the cost of the power supply equipment, and the power capacity, the drive device such as the drive motor 66 is moved to a predetermined unbalance that is smaller than the maximum load unbalance amount at the left and right positions. It can be considered to be small enough to start up to the balance amount. However, in this case, as described above, when the vehicle is shifted to the left and right and the load unbalance amount at the left and right positions is maximized, stable circulation operation may be difficult. For example, the rotational direction in which the cage group 62 is circulated is the direction in which the calling cage 60 arrives in the shortest time regardless of the load on the left and right, but the shortest when the unbalance amount is close to the maximum. It may be difficult to operate in the direction of calling.

  In addition, when the temperature is low, the viscosity of the lubricating oil of the drive equipment increases, the speed of the speed reducer decreases, and the load that can be rolled up decreases. Therefore, if the high load side is rotated in the winding direction in a state where the temperature is low and the unbalanced state is obtained, a start-up failure or the like may occur.

  Accordingly, an object of the present invention is to provide a vertical circulation parking facility capable of performing a stable circulation operation and a driving method thereof while reducing the size of a drive device such as a drive device to suppress the power supply capacity.

  In order to achieve the above object, a vertical circulation parking facility according to the present invention is characterized in that a main chain is wound between an upper sprocket and a lower sprocket that are spaced apart from each other, and an attachment link provided on the main chain. A vertical circulation parking facility configured to circulate a cage group composed of a plurality of cages suspended on the sprocket by rotating the sprocket with a drive device, and rotating the drive device for circulating the cage group A control unit that outputs a start command by designating a direction, and when the control unit determines that the load balance at the left and right positions of the cage group is in an unbalanced state exceeding a set value, The start-up command in which the heavy load side of the cage group is in the lowering direction is output to the drive device. The “unbalanced state” in the specification and claims refers to a state in which the load balance at the left and right positions of the circulating cage group with respect to the center of the vertical circulation parking facility is unbalanced.

  With this configuration, when the control unit determines that the load balance at the left and right positions of the cage group exceeds the set value, the rotation direction is determined so that the heavy load side of the cage group is in the lowering direction at the next start-up. Thus, the drive device is started, and it is possible to reduce the load on the drive device at the time of starting by avoiding the reverse load acting when the brake is released. Further, since the load on the driving device when accelerating can be reduced, the capacity of the driving device can be reduced. Moreover, even if the temperature drops and the viscosity of the lubricating oil increases and the efficiency of the reducer, etc. decreases, it starts with the heavy load side in the lowering direction, so it is possible to avoid overload of the drive device at the time of startup it can. Therefore, the driving device and the power source capacity can be reduced.

  Further, the control unit may be configured to manage the vehicle accommodation state in the cage group as an actual empty state and determine the unbalanced state at the left and right positions from the actual empty state. The “real sky state” in the specification and claims refers to a state including a “real vehicle state” in which the vehicle is mounted and an “empty vehicle state” in which the vehicle is not mounted.

  If configured in this way, the actual empty state in the cage group is managed by the control unit, the difference in the number of actual vehicles in the left and right cages is calculated from the actual empty state, and if the difference exceeds the set value, the unbalanced state Since the drive device is started by determining the rotation direction so that the large load side of the cage group is in the lowering direction at the next start-up, the drive device capacity is reduced, and the drive device and power supply are reduced in size. Can be planned.

  Moreover, the said control part may be comprised so that the vehicle accommodated in the said cage in an entrance part may be detected with a real vehicle detection sensor, and the actual empty state in each cage of the said cage group may be managed.

  If comprised in this way, it can detect in which cage the vehicle is accommodated in the boarding part, and can determine rapidly an unbalanced state from the actual sky state of the vehicle in the left-right position of the cage group 12.

  Moreover, the said control part may be comprised so that the unbalanced state in a left-right position may be determined from the load of the drive device just before the circulation operation stop of the said cage group. As the “load of the driving device”, a load torque of the driving device, a load of a current value, or the like can be used.

  If comprised in this way, the imbalance state in the left-right position of a cage group can be determined from the load of a drive device, and the circulation operation | movement direction of a cage group in the next starting can be determined according to it.

  The control unit may be configured to be switchable between a setting for determining the unbalanced state and a setting for not performing the determination.

  If comprised in this way, in cold districts etc., it can set arbitrarily so that determination of an imbalance state may be performed according to temperature, and an operating condition can be changed according to temperature and time. This switching can be automatic or manual.

  In addition, the control unit may be configured to select a cage of a newly accommodated vehicle at a position where the cage group does not cause the unbalanced state in the left-right position.

  With this configuration, the control unit manages the actual empty state of the cage and the unbalanced state at the left and right positions, and selects and accommodates the cage so that it does not become unbalanced at the left and right positions when the vehicle is housed. it can.

  On the other hand, in the operation method of the vertical circulation parking facility according to the present invention, a main chain is wound between an upper sprocket and a lower sprocket that are separated from each other in the vertical direction, and is suspended on an attachment link provided on the main chain. An operation method of a vertical circulation parking facility configured to rotate a cage group composed of a plurality of cages by rotating with a drive device, wherein the load balance at the left and right positions of the cage group exceeds a set value. When it is determined that the vehicle is in a balanced state, the drive device is activated so that the heavy load side of the cage group is in the lowering direction at the next activation.

  With this configuration, if it is determined that the load balance at the left and right positions of the cage group is in an unbalanced state exceeding the set value, the drive device is activated so that the heavy load side of the cage group is in the lowering direction at the next activation, and the brake It is possible to reduce the load on the driving device at the time of starting by avoiding a reverse load acting when opened. Further, since the load on the driving device when accelerating can be reduced, the capacity of the driving device can be reduced. Moreover, even if the temperature drops and the viscosity of the lubricating oil increases and the efficiency of the reducer, etc. decreases, it starts with the heavy load side in the lowering direction, so it is possible to avoid overload of the drive device at the time of startup it can. Therefore, the drive motor capacity and the power supply capacity can be reduced.

  The housing state of the vehicle housed in the cage may be managed as a real sky state, and the unbalanced state at the left and right positions of the cage group may be determined from the real sky state.

  If comprised in this way, it determines the rotation direction so that the heavy load side of a cage group may become a lowering direction at the time of the next starting by determining the unbalanced state of the left-right position from the actual sky state of the vehicle in a cage group, and a drive device Therefore, the capacity of the drive device can be reduced, and the drive device and the power supply can be reduced in size.

  Further, the unbalanced state at the left and right positions may be determined from the load of the driving device immediately before stopping the circulating operation of the cage group.

  If comprised in this way, the imbalance state in the left-right position of a cage group can be determined from the load of a drive device, and the circulation operation | movement direction of a cage group in the next starting can be determined according to it.

  According to the present invention, even when the cage group is in a large unbalanced state at the left and right positions, it is possible to start up so that the heavy load side is in the lowering direction and perform stable circulation operation. This makes it possible to reduce the capacity of the drive device and the power supply capacity. Moreover, even if the mechanical efficiency of the drive device is reduced due to an increase in the viscosity of the lubricating oil due to a low temperature, the operation becomes possible.

FIG. 5 is a front view showing an example of cage arrangement in a general vertical circulation parking facility.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following embodiment, an example of the vertical circulation parking facility 1 in which one cage 10 is arranged at each of the upper end and the lower end and 11 cages 10 are arranged at the left and right positions and can accommodate a total of 24 vehicles V. Explained. In addition, the vehicle V accommodated in the cage 10 actually has a difference in weight depending on the size of the vehicle V, but in the following description, it is assumed that the weights of all the vehicles V are substantially equal. Furthermore, in the following embodiment, the drive motor 16 having a capacity that can be activated in the winding direction even when the vehicle V is housed in twelve cages 10 that are half of all the cages 10 and shifted to the left and right sides and become unbalanced. As described above, it is necessary to increase the size of the drive equipment and the equipment constituting the power supply equipment, which requires a large amount of money, and to increase the contract power supply capacity of the parking equipment. Therefore, an example in which a drive motor (drive device) 16 that can be activated in the winding direction up to an unbalanced load of the vehicle V for seven vehicles will be described in order to reduce the cost and power supply capacity of the drive equipment and the like.

  As shown in FIG. 1, the vertical circulation parking facility 1 of this embodiment includes a pair of front and rear upper sprockets 5 and 6 and a pair of front and rear sprockets 6 provided at positions spaced apart from each other inside the parking tower 2. An endless main chain 7 is wound between the upper sprocket 5 and the lower sprocket 6. The main chain 7 is provided with attachment links 8 at predetermined pitches, and cages 10 on which the vehicles V are mounted are suspended from the attachment links 8.

  Then, the upper sprocket 5 is rotated by a drive motor 16 as a drive device provided on the upper frame 3 of the parking tower 2, whereby the main chain 7 is rotated and a cage group comprising the plurality of cages 10. 12 is circulated inside the parking tower 2. The speed of the circulation operation of the cage group 12 is controlled by secondary resistance control and frequency control of the drive motor 16.

  The cage group 12 circulated by the drive motor 16 moves in an arc shape in the upper and lower portions of the parking tower 2 and moves in the vertical direction in the vertical portion of the left and right positions. The cage 10 is stopped at the entry portion 4 located at the lowermost part of the parking tower 2, and the vehicle V is loaded into or out of the pallet (floor plate) 11 of the cage 10.

  In the vertical circulation parking facility 1 in the state shown in FIG. 1, one cage 10 is disposed at the upper end and the lower end, and 11 cages 10 are disposed at the left and right positions. The actual empty state of the cage 10 in this embodiment is an actual vehicle state in which ten vehicles V are accommodated in the right cage 10 and two in the left cage 10, and a total of 12 vehicles are accommodated. It is in a state.

  In such a vertical circulation parking facility 1, when newly entering the vehicle V, the empty cage 10 at a position away from the cage 10 in which the vehicle V is already accommodated is called and the load at the left and right positions of the cage group 12 is called. Does not become a big unbalanced state. However, since the entry and exit of the vehicle V are arbitrarily performed, the cage 10 housing the vehicle V on the right side may be shifted and stopped as illustrated. In this embodiment, the vertical circulation parking facility 1 in the state shown in FIG. 1 is taken as an example.

  FIG. 2 is a configuration diagram for detecting the actual empty state of the vehicle V in the vertical circulation parking facility 1. An actual vehicle detection sensor 20 is provided in the entry section 4, and the actual vehicle / sensor of each cage 10 is detected by the actual vehicle detection sensor 20. An empty vehicle condition is detected. The actual vehicle detection sensor 20 is connected to the control unit 30, and the control unit 30 indicates that the actual empty state at the time when the loading and unloading at the loading unit 4 is completed is the identification information of each cage 10 (for example, the cage 10 Number). Therefore, even if the cage 10 is moved by the circulation operation, the control unit 30 stores in which cage 10 the vehicle V is accommodated and at which position. The control unit 30 drives the drive motor 16 by the drive unit 15.

  In addition, the control unit 30 is provided with an inversion threshold setting unit 31 that determines an unbalanced state in which the large load side at the left and right positions of the cage group 12 is activated in the direction of lowering as described below. The inversion threshold setting unit 31 assumes that the unbalanced state at the left and right positions of the cage group 12 is proportional to the number of actual vehicles housed in the cage 10 at the left and right positions. It is set as (setting value). That is, in the vertical circulation parking facility 1 of this embodiment, the magnitude of the unbalance load is determined by the difference in the number of vehicles V (hereinafter also referred to as “unbalanced number”). The difference in the number of actual vehicles is calculated, and if the difference in the number of vehicles exceeds a threshold value, it is determined that a large unbalanced state has occurred in the left and right positions of the cage group 12. As described above, the vertical circulation parking facility 1 includes the drive motor 16 that can start up to seven unbalanced loads, so that the difference in the number of the seven vehicles is set as a threshold value (set value). If an unbalanced load is set due to a difference in the number of units that is set in the unit 31 and exceeds the threshold value (which will also be referred to as “overloaded number” in the following description), as will be described below, The drive motor 16 is controlled so as to start in the direction to wind down.

  Next, a flowchart of an example of cage circulation operation in the vertical circulation parking facility 1 will be described with reference to FIG. When starting, it is determined whether there is a call registration of the cage 10 (S1). If there is a call registration, the number of unbalanced vehicles V (unbalanced load) at the left and right positions of the cage group 12 at that time is calculated (S2).

  Then, it is determined whether the unbalanced number obtained by the calculation of the unbalanced number is an overloaded number or exceeds it (S3). If the unbalanced number is less than the overloaded number in this determination (S3) (7 or less in this embodiment), the rotation direction is set so that the drive motor 16 is rotated by a normal procedure (S4). That is, the rotation direction in which the time for moving the call cage 10 to the loading section 4 is the shortest is set.

  On the other hand, if the number of unbalanced vehicles is overloaded or exceeded (8 or more in this embodiment) in the above determination (S3), the number of accommodated vehicles in the left and right positions regardless of the position of the call cage 10. The rotation direction of the drive motor 16 is set in the direction of lowering the large heavy load side (S5). That is, the rotation direction is set regardless of whether or not the time for moving the call cage 10 to the loading section 4 is the shortest.

  Thereafter, in any of the above cases, an operation command is issued and activated (S6), the cage group 12 is circulated, and the calling cage 10 arrives at the entry section 4 (S7). Then, a stop command is issued (S8).

  Thus, in the above example, when the unbalanced state at the left and right positions is determined from the actual sky state of the vehicle V, and it is determined that the number of unbalanced items exceeds the threshold value, the heavy load at the left and right positions of the cage group 12 is determined. Since a rotation command is issued to the drive motor 16 so as to lower the side, a load in the reverse direction is not applied by releasing the brake when the drive motor 16 is activated. Therefore, even with a downsized drive device, stable circulation operation can be started.

  4 (a) and 4 (b) show that the number of unbalanced vehicles exceeds the threshold (set value) in the cage circulation operation example shown in FIG. 3 from the vertical circulation parking facility 1 in the state shown in FIG. This is an example in which the vehicle V marked with “☆” is issued. In the state shown in FIG. 1, two vehicles V are accommodated in the left cage 10, and ten vehicles V are accommodated in the right cage 10 while being offset. Therefore, the load balance at the left and right positions of the cage group 12 is in an unbalanced state in which unbalance loads for eight (10 units−two units) act on the right side.

  Therefore, in the determination of (S3) in FIG. 3 above, it is determined that the number of unbalanced vehicles exceeds the threshold value, and when the vehicle V is delivered by the normal means, the rotation direction of the circulation operation is the shortest time for the calling cage 10 The rotation direction is set so that the side with the larger number of units (the heavy load side) becomes the lowering direction, not the arrival rotation direction.

  That is, even when the call cage 10 is located on the left side at the time of activation (FIG. 1), as shown in FIG. 4 (a), the cage group 12 is driven so as to rotate clockwise to wind down the right heavy load side. The motor 16 is activated.

  Therefore, according to the vertical circulation parking facility 1, even when the drive motor 16 can be activated in the winding direction only up to seven unbalance loads as described above, the heavy load side is lowered. It is possible to start up stably without stopping due to overload during startup. The state shown in FIG. 4 (a) is a diagram in the middle of calling the vehicle V indicated by ☆, and in this state, there are four vehicles V in the left cage 10 and seven vehicles V in the right cage 10. Since it is in the housed state, the load balance at the left and right positions is an unbalanced load of (7 units−4 units =) 3 units, and the cage group 12 can be stably circulated.

  Then, as shown in FIG. 4 (b), the calling cage 10 is disposed in the loading section 4, and the vehicle V is discharged from the cage 10. The load balance at the left and right positions in the state shown in FIG. 4 (b) is an unbalanced state in which the unbalanced load of (7 units−3 units =) 4 units acts on the left side. The vertical circulation parking facility 1 is provided with the drive motor 16 that can be activated in the winding direction up to the unbalanced load of the vehicle V for seven vehicles. Can be started by rotating the drive motor 16 in the direction in which is shortest.

  By the way, in the above example, the left / right position unbalanced state is determined based on the difference in the number of actual vehicles in the left / right position of the cage group 12. However, the determination of the unbalanced state may be made based on the load torque of the drive motor 16. In the determination of such an unbalanced state, the control unit 30 monitors the load torque of the drive motor 16, and when the load torque exceeds a predetermined threshold value (set value), the cage group 12 is unloaded at the left and right positions. It is determined that the balance state has been reached, and the drive motor 16 is controlled to start in the direction of lowering the heavy load side at the next startup. For example, in the case of the inverter-controlled drive motor 16, the determination of the unbalanced state may be performed by monitoring the load torque of the drive motor 16 in the inverter.

  Further, the determination of the unbalanced state at the left and right positions of the cage group 12 may be performed from the output (load) and the rotation direction immediately before the drive motor 16 is stopped. In the determination of such an unbalanced state, the control unit 30 monitors the output of the drive motor 16 and the rotation direction, and whether or not the output immediately before the stop exceeds a predetermined threshold (for example, 80% of the rated output). If the output at the time of stop exceeds the threshold value (set value), the drive motor 16 is controlled to start in the direction of lowering the large load side (reverse rotation from the stop time) at the next start. .

  The determination of the unbalanced state and the determination of the unbalanced state based on the difference in the number of actual vehicles may be determined according to the size of the vertical circulation parking facility 1 and the driving method of the drive motor 16.

  On the other hand, when the driving equipment such as a speed reducer provided in the parking facility 1 becomes low temperature, the viscosity of the lubricating oil increases and the mechanical efficiency decreases. However, as described above, the unbalanced state is determined based on the difference in the number of actual cars in the cage group 12, the torque of the drive motor 16, the output of the drive motor 16, and the like, and the unbalanced state exceeds a predetermined threshold (set value). Even if it starts, the circulation operation | movement can be performed by starting in the direction which winds down a heavy load side, Therefore A starting failure does not arise. Then, once the cage group 12 is circulated, the temperature of the lubricating oil rises and the viscosity can be weakened, and the mechanical efficiency of the speed reducer and the like can be improved.

  Further, the increase in the viscosity of the lubricating oil in the driving device or the like due to the low temperature occurs depending on the region or season in which the vertical circulation parking facility 1 is installed. Therefore, a low temperature setting unit 32 for low temperatures may be provided in the control unit 30 (FIG. 2). The low temperature setting unit 32 determines that the temperature of the lubricating oil has decreased and the efficiency has been lowered when a state of no operation at a predetermined low temperature state continues for a certain period of time, and the high load side of the unbalanced state at the left and right positions of the cage group 12 is determined. It starts up in the direction of lowering. Even if the low temperature setting unit 32 automatically determines the low temperature state according to the temperature and the season, the manager of the parking facility 1 manually turns on the low temperature setting unit 32 arbitrarily according to the temperature and the season. The low temperature state may be determined by switching. Further, the low temperature setting unit 32 reduces the control of starting the drive motor 16 in the direction of lowering the heavy load side at the next start-up in the unbalanced state due to the difference in the number of eight or more at low temperatures to seven. May be.

  As a result, even in a state where a large unbalanced load is applied such that the viscosity of the lubricating oil in the drive device or the like increases at a low temperature, the mechanical efficiency decreases, and the left and right positions of the cage group 12 are in an unbalanced state. The motor 16 can be started. And after rotating once and lubricating oil becomes warm and viscosity becomes weak, it can judge that the temperature of lubricating oil rose and can operate in a normal state.

  As described above, according to the vertical circulation parking facility 1, even if the load is shifted to the left and right due to the accommodation state of the vehicle V in the cage group 12 and the unbalanced state exceeds the set value, the heavy load side is wound. Since it starts in the lowering direction, it is possible to avoid a sudden load in the reverse direction when the brake is released, and it is possible to reduce the driving force required for the driving motor 16 and reduce the load on the driving motor 16 when accelerating. Accordingly, it is possible to configure the vertical circulation parking facility 1 capable of stable circulation operation while reducing the capacity of the drive motor 16 and reducing the size of the drive device and the power supply capacity of the parking facility 1.

  Further, the determination of the unbalanced state at the left and right positions of the cage group 12 is based on whether the vehicle V is in an actual sky state, the torque immediately before the drive motor 16 is stopped, the load on the drive motor 16, etc. exceeds a threshold value (set value). It can be detected and activated in the direction of lowering the heavy load side of the cage group 12 at the next activation, and it is suitable for the size and area of the vertical circulation parking facility 1 and the drive system of the drive motor 16. It is possible to configure the vertical circulation parking facility 1 that can determine the balance state.

  Further, even in the case of the vertical circulation parking facility 1 in a cold region, even if the viscosity of the lubricating oil increases and the mechanical efficiency of the driving equipment decreases, the heavy load of the cage group 12 in an unbalanced state A vertical circulation parking facility 1 that can be stably activated by starting in the direction in which the side is lowered, and capable of a stable circulation operation while reducing the size of the driving device and the power supply capacity of the parking facility 1 is configured. It becomes possible.

  In the above-described embodiment, a drive motor (drive device) 16 that can be activated in the winding direction up to an unbalanced load of the vehicle V for 7 vehicles is provided for the load of the vehicle V for 12 vehicles, which is half of the entire cage 10. Although the example which was made to explain was explained, it suffices to determine how many vehicles V are equipped with a drive motor (drive device) 16 that can be activated in the winding direction depending on conditions such as the number of units accommodated and the installation location. The invention is not limited to the above embodiment.

  In the above embodiment, the vertical circulation parking facility 1 capable of accommodating 24 cars has been described as an example. However, the number of vehicles V accommodated is an example, and the load balance unbalanced state at the left and right positions is also an example. It is not limited to the configuration of the embodiment. Furthermore, in the above embodiment, the description has been made assuming that all the vehicle weights are substantially equal. However, since the difference in vehicle weight due to the size of the vehicle V actually affects the driving load, the vehicle weight difference of the vehicle V is taken into consideration. You may comprise.

  Furthermore, in the above-described embodiment, the lower-entry-type vertical circulation parking facility 1 has been described as an example. However, the upper-entry method and the intermediate-entry method can be applied in the same manner. It is not limited to.

  Moreover, the said embodiment has shown an example, The various change in the range which does not impair the summary of this invention is possible, and this invention is not limited to the said embodiment.

  The vertical circulation parking facility according to the invention of the present application can be used when it is desired to perform a stable circulation operation while miniaturizing a drive device to suppress a power source capacity.
