【Example】

 Hereinafter, an embodiment of the vertical circulation type multi-level parking facility of the present invention will be described with reference to FIG. 1, which is an overall plan view of the circulation mechanism A, FIG. Description will be made based on a schematic front view, the control flowchart of FIG. 4, and the graph of FIG.

As shown in FIG. 1 and FIG. 3, the vertical circulation type multi-level parking facility according to the embodiment of the present invention is arranged in a pair in a vertical direction in a parking building H having a loading / unloading room H1, and a pair of front and rear sprockets. A chain (an example of a rope) 2 is stretched in an annular shape on each of 1 and a large number of cages 4 for mounting a vehicle C are suspended on the chains 2 via pins 3 and the like.

A main motor M1 for driving a circulation mechanism A for circulating the chain 2 in a vertical plane is arranged at an intermediate position between the front and rear sprockets 1, and the circulation mechanism A is The brake 6, the speed reducer 7 and the coupling 9, which are arranged in order to connect the rotary shaft 1a of the sprocket 1 to one side 5a of the output shaft 5 of the main motor M1, and the output shaft 5 of the main motor M1. The other side 5b is composed of a speed reducer 8, a coupling 9 and the like which are sequentially arranged to connect the rotating shaft 1b of the other sprocket 1.

Further, as shown in FIGS. 1 and 2, an auxiliary motor M2 is arranged side by side with the main motor M1, and the output shaft 10 of the auxiliary motor M2 is connected to the main mechanism 11 and an electromagnetic clutch 12 so that the main shaft 11 The output shaft 5 of the motor M1 can be connected to and detached from one side 5a of the output shaft 5. A roller chain or the like may be used instead of the gear mechanism 11. A current value detector (not shown) is connected to the main motor M1.

Further, the parking equipment of the present invention is provided with a control device (not shown) for controlling the drive of the main motor M1, the auxiliary motor M2 and the electromagnetic clutch 12, and the control device includes the current detector. It has a function of outputting a drive signal to the electromagnetic clutch 12 and a drive signal to the auxiliary motor M2 in accordance with a current value detection signal from a predetermined value or more.

In the above-described configuration, the facility is used by the administrator, and the administrator selects which cage 4 the vehicle C is to be placed in and stores the vehicle C in the parking building H in a well-balanced manner.

The drive control of the control device at this time will be described with reference to FIG. As shown in the figure, when the cage 4 for the purpose of loading and unloading is called by an operation button or the like, the control device controls to start driving the main motor M1. When the current value detection signal from the current detector is 250% or less of the rating of the main motor M1 when the main motor M1 is driven, the drive of the main motor M1 is continued. As a result, the sprocket 1 rotates, and the target cage 4 suspended by the chain 2 approaches the loading / unloading chamber H 1, so a deceleration signal is output to the main motor M1 at an appropriate timing, and the driving is stopped. The goods have been put in and taken out. Then, it waits for the vehicle C to be placed on the cage 4 or to be output from the cage 4, and again outputs a drive signal to the main motor M1.

By the way, when the manager cannot sufficiently manage the warehousing and unloading, a large number of the vehicles C may be placed on the cage 4 suspended on one side of the chain 2. In such a case, when it is detected that the current value supplied to the main motor M1 is 250% or more of the rated value when the main motor M1 is driven, that is, the main motor M1 is suspended on one side of the chain 2. When a large number of vehicles C are placed in the cage 4 (for example, the difference from the number of vehicles C placed in the cage 4 suspended on the other side of the chain 2 is 9 or more), The control device outputs a drive signal to the auxiliary motor M2 and also outputs a drive signal to the electromagnetic clutch 12. Then, the output shaft 5 of the main motor M1 is connected to the output shaft 10 of the auxiliary motor M2, the driving force of the auxiliary motor M2 is added to the driving force of the main motor M1, the sprocket 1 rotates, and the cage 4 moves in the vertical plane. To rotate. After that, when the cage 4 approaches the loading / unloading room H1, a deceleration signal is output to the main motor M1 and the auxiliary motor M2, then the driving of the main motor M1 and the auxiliary motor M2 is stopped, and the drive stop signal is sent to the electromagnetic clutch 12. Is output and the output shaft 10 of the auxiliary motor M2 is disengaged from the output shaft 5 of the main motor M1 to complete the loading / unloading.

It should be noted that in FIG. 5, a graph D indicated by a one-dot chain line is a conventional one, and the predicted maximum number of single loads (the number of vehicles C mounted on the cage 4 on one side of the chain 2 and The case where the circulation mechanism A is driven by using a motor having a large driving force determined by the difference between the number of vehicles C mounted on the cage 4 on the other side of the vane 2) is shown. Further, graphs E1 and E2 shown by the solid line below the graph D indicate those of the present embodiment, and E1 has a maximum number of single loads of, for example, 9 units, and the circulation mechanism A is formed using only the main motor M1. E2 indicates the case where the circulation mechanism A is driven by using both the main motor M1 and the auxiliary motor M2.

Further, 90% of the entire facility operating rate is between 1 and 9 single-loading units, and if the number of single-loading units is 1 to 13, 95% or more of the overall facility operating rate is occupied. In other words, 90% of the total facility operation rate will drive only the main motor M1, and the power consumption equivalent to the area of the shaded area F1 in the figure can be saved. Even if the circulation mechanism A is driven by using both the main motor M1 and the auxiliary motor M2, the power consumption corresponding to the area of the shaded portion F1 can be saved.

In this way, the auxiliary motor M2 having the output shaft 10 which can be freely connected and disconnected is provided on the output shaft 5 of the main motor M1, and when the current value supplied to the main motor M1 exceeds a predetermined value, the auxiliary motor M2 If the output shaft 10 of M2 is connected to the output shaft 5 of the main motor M1 to drive it, even the main motor M1 having a smaller driving force than the conventional one can be suspended on one side of the chain 2. This can be dealt with by applying the driving force of the auxiliary motor M2 at the time of loading and unloading when many vehicles C are placed in the cage 4.

Further, in a normal use state in which the vehicle C is placed on an arbitrary cage 4 hung on both sides of the chain 2, the main motor M1 having a small driving force is sufficient for the consumption. Electric power is saved and energy can be saved.
