A pair of turning sheaves 54 are arranged behind the space above the hoistway.
The four cables 40 are composed of a pair of first cables 41 and a pair of second cables 42.
The pair of first cables 41 suspend the front of the lift cage 30.
The pair of second cables 42 suspend the rear of the lift cage 30.
A pair of first cables 41 are connected to the lift cage 30 at one end that is lowered downward from the hoisting sheave 53, and horizontally spanned between the hoisting sheave 53 and the turning sheave 54. 54 and the drive sheave 51 are horizontally stretched, wound over a horizontal arc of the drive sheave over 180 degrees, wound around the idle sheave 52, and lowered from the idle sheave 52 to the lower end.

The hoisting device 50 winds up the cable 40 and stops the lift cage 30 next to one of the plurality of storage shelves. The cage support device 70 supports the lift cage 30 on the main structure of the building.
A transfer device (not shown) transfers the pallet on which the vehicle is placed to the storage shelf, and the warehousing is completed.

Next, the operation when the vehicle is taken out from the parking device will be described.
The hoisting device 50 winds up the cable 40 and stops the lift cage 30 next to one of the plurality of storage shelves. The cage support device 70 supports the lift cage 30 on the main structure of the building.
The transfer device transfers the pallet on which the vehicle is mounted from the storage shelf to the lift cage.

The cable 40 wound around the drive sheave has one end connected to the lift cage 30 and the other end connected to the counterweight.
When the weight of the counterweight is appropriately selected, the power consumed by the hoisting device can be minimized.
For example, the weight of the lift cage is selected as 2500 kg, the weight of the pallet as 500 kg, and the weight of the counterweight as 3500 kg. In this way, when a vehicle having a weight of 2500 kg is put on the lift cage, a weight of 5500 kg acts on one end of the cable and a weight of 3500 kg acts on the other end of the cable. When the vehicle is not placed in the lift cage, a weight of 2500 kg acts on one end of the cable, and a weight of 3500 kg acts on the other end of the cable. The lift cage is accelerated or decelerated and moved up and down into the hoistway while supporting a torque that is the difference between the torque caused by the force acting on one side of the cable and the torque acting on the other side.

The type of the hoisting device may be a type in which a cable is wound around a sheave that is rotationally driven, and torque acting on the sheave is transmitted to the cable by a frictional force between the sheave of the cable. This type of hoisting device has a characteristic that torque transmission becomes unstable when the difference between the weight acting on one end of the cable wound around the sheave and the weight acting on the other end of the cable becomes large. Have.
Generally, weight reduction of the lift cage, pallet, and counterweight can reduce the weight of the parking device and save driving power. However, if the weight of the lift cage and the weight of the pallet and counterweight are reduced Even if the weight of the counterweight is properly selected, the above weight difference cannot be kept within a certain value when the vehicle is mounted or not mounted, and torque transmission becomes unstable. Become.

  In the first type of operation format, the auxiliary drive sheave 61 is rotationally driven or idling according to the weight of the vehicle placed on the lift cage 30 when the vehicle enters and exits.

When the weight of the vehicle placed on the lift cage 30 is less than a predetermined weight, the drive mechanism 55 may rotationally drive the drive sheave 51 and the auxiliary drive mechanism 62 may idle.
For example, the vehicle type of the vehicle that has been requested to enter or leave is checked, and the standard weight (standard weight) of the vehicle type is compared with a predetermined weight.

The cable 40 is wound up and down by the frictional force of the drive sheave 51 alone, and the lift cage 30 is moved up and down.
Further, when the weight of the vehicle placed on the lift cage 30 exceeds a predetermined weight, both the drive mechanism 55 and the auxiliary drive mechanism 62 are operated. The cable 40 is wound up and down by the frictional force of both the drive mechanism 55 and the auxiliary drive mechanism 62, and the lift cage 30 is moved up and down.

The clutch mechanism may separate the rotation of the auxiliary drive mechanism and the rotation of the auxiliary drive sheave when the weight of the vehicle placed on the lift cage falls below a predetermined weight.
For example, the vehicle type of a vehicle that has requested entry or exit is checked, and the standard weight of the vehicle type is compared with a predetermined weight.
For example, when the standard weight of the vehicle type on the lift cage falls below a predetermined weight, the clutch mechanism is operated to separate the rotation of the auxiliary drive mechanism 62 from the rotation of the auxiliary speed reducer 64 and idle the auxiliary drive sheave 61. The drive sheave 51 is rotated by operating the drive mechanism. The cable 40 is wound up and down by the frictional force of the drive sheave 51 alone, and the lift cage 30 is moved up and down.
In addition, when the weight of the vehicle placed on the lift cage exceeds a predetermined weight, the clutch mechanism is operated to connect the rotation of the auxiliary drive mechanism 62 and the rotation of the auxiliary speed reducer 64 to thereby connect the drive mechanism 55 and the auxiliary drive mechanism.

The auxiliary drive mechanism 62 is idled to cause the auxiliary drive sheave 61 to idle, and the drive mechanism is operated to drive the drive sheave 51. Drive to rotate. The cable 40 is wound up and down by the frictional force of the drive sheave 51 alone, and the lift cage 30 is moved up and down.

The cable 40 is wound up and down by the frictional force of both the drive mechanism 55 and the auxiliary drive mechanism 62, and the lift cage 30 is moved up and down.

The clutch mechanism 63 may separate the rotation of the auxiliary drive mechanism 62 and the rotation of the auxiliary drive sheave 61 when the lift cage is not loaded with a vehicle.
For example, when the lift cage 30 is not loaded with a vehicle, the clutch mechanism 63 is operated to separate the rotation of the auxiliary drive mechanism 62 and the rotation of the auxiliary speed reducer 64 to idle the auxiliary drive sheave and operate the drive mechanism 55. Thus, the drive sheave 51 is rotationally driven. The cable 40 is wound up and down by the frictional force of the drive sheave 51 alone, and the lift cage 30 is moved up and down.
When the lift cage 30 is on the vehicle, the clutch mechanism 63 is operated to connect the rotation shaft of the auxiliary drive mechanism 62 and the rotation shaft of the auxiliary speed reducer 64, and both the auxiliary drive mechanism and the drive mechanism are operated. Thus, both the drive sheave 51 and the auxiliary drive sheave 61 are rotationally driven. The cable 40 is wound up and down by the frictional force of both the drive mechanism 55 and the auxiliary drive mechanism 62, and the lift cage 30 is moved up and down.

  In the third type of operation format, the auxiliary drive sheave 61 is rotationally driven or idling according to the magnitude of the suspension force that suspends the lift cage when the vehicle enters and exits.

When the lifting force for hanging the lift cage falls below a predetermined value, the drive mechanism 55 may rotationally drive the drive sheave 51 and the auxiliary drive mechanism 62 may idle.
For example, when the lifting force for suspending the lift cage is less than a predetermined value, power is not supplied to the auxiliary drive mechanism 62. The auxiliary drive mechanism 62 is idled to cause the auxiliary drive sheave 61 to idle, and the drive mechanism is operated to drive the drive sheave. 51 is rotated. The cable 40 is wound up and down by the frictional force of the drive sheave 51 alone, and the lift cage 30 is moved up and down.
When the lifting force for hanging the lift cage exceeds a predetermined value, both the drive mechanism 55 and the auxiliary drive mechanism 62 are operated, and both the drive sheave 51 and the auxiliary drive sheave 61 are rotationally driven. The cable 40 is wound up and down by the frictional force of both the drive mechanism 55 and the auxiliary drive mechanism 62, and the lift cage 30 is moved up and down.

The clutch mechanism may separate the rotation of the auxiliary drive mechanism and the rotation of the auxiliary drive sheave when the lifting force for hanging the lift cage is below a predetermined value.
For example, when the load for hanging the lift cage is less than a predetermined weight, the clutch mechanism is operated to separate the rotation of the auxiliary drive mechanism 62 and the rotation of the auxiliary speed reducer 64 to idle the auxiliary drive sheave and operate the drive mechanism 55 Thus, the drive sheave 51 is rotationally driven. The cable 40 is wound up and down by the frictional force of the drive sheave 51 alone, and the lift cage 30 is moved up and down.
When the lifting force for hanging the lift cage exceeds a predetermined value, both the drive mechanism 55 and the auxiliary drive mechanism 62 are operated, and both the drive sheave 51 and the auxiliary drive sheave 61 are rotationally driven. The cable 40 is wound up and down by the frictional force of both the drive mechanism 55 and the auxiliary drive mechanism 62, and the lift cage 30 is moved up and down.
