Description

  The present invention relates to a vertical circulation parking device for parking a vehicle and a parking device management method for managing the vertical circulation parking device. In particular, the present invention relates to a vertical circulation parking device and a parking device management method that are characterized by a configuration that allows stable driving.

The pallet cage is a bowl-like structure on which a vehicle is placed.
An upper sprocket is provided above the lower sprocket.
The main chain is an infinite loop-shaped mechanical element that spans between the upper sprocket and the lower sprocket. The pallet cage is connected to the main chain at a predetermined pitch.
The chain rail is a rail-like structure that guides the main chain movably in the vertical direction between the upper sprocket and the lower sprocket.

The chain is a mechanical element in which a chain plate is connected to a chain pin at a predetermined pitch. The guide roller is a flanged roller having a rotation axis that matches the rotation axis of the chain pin. The chain attachment is a structural member that is supported by the chain and suspends the pallet cage at the tip.

When the upper sprocket rotates, the lower sprocket follows and rotates, the right part of the endless loop of the main chain moves to one of the upper and lower sides, and the left part of the endless loop of the main chain moves to the other upper and lower side .
The roller portion of the guide roller fits in the guide groove of the chain rail and rolls up and down.
The roller part is fitted in the guide groove. Usually, the depth at which the roller portion is fitted in the guide groove is set to be deeper than a predetermined design limit value in design.
The actual depth of fitting is constantly changing.
This is due to deformation of the pallet cage, chain rail, and chain attachment, and overall rattling.
Since the stability of driving of the parking device is impaired when the depth of the fitting becomes shallow, it is a subject of periodic inspection. When a sign that the depth of insertion is less than the design limit value is found, the device is adjusted and parts are replaced.

Further, when a vehicle having a weight more than the design schedule is parked, the pallet cage may be elastically deformed more than the design schedule, and the depth at which the pallet cage is temporarily fitted may become shallow.
Accordingly, there has been a demand for continuous monitoring of how the chain rail guides the main chain.

In addition, the service person can monitor the state of the parking apparatus in charge at the service station and see a warning signal.
As a result, the service person knows that the engagement between the main chain 50 and the chain rail 60 is loose for some reason.

Next, the detection output value processing procedure of the parking apparatus according to the second embodiment will be described.
FIG. 9 is an operation explanatory view of the parking apparatus according to the second embodiment of the present invention.
In the second embodiment, the front detection distance Xf to the front surface of the front service chain 50f detected using the front proximity sensor 70f and the rear surface of the rear service chain 50r detected by the rear proximity sensor 70r. When the total detection distance Xf + Xr, which is the sum of up to the rear detection distance Xr, exceeds a predetermined value, a warning signal is output.
The front detection distance Xf corresponds to the shortest front detection output value Sfi that appears at predetermined time intervals in the time-series front detection output value Sf output by the front proximity sensor 70f, and the rear detection distance Xr is the rear proximity sensor. This corresponds to the shortest rear detection output value Sri that appears at predetermined time intervals in the time-series rear detection output value Sr output by 70r.

When selecting the shortest rear detection output value Sri or the shortest front detection output value Sfi, the notch-like or spike-like detection output value in the time-series detection output value may be ignored as an abnormal value.
The remote monitoring system outputs a warning signal when the sum Xfi + Xri of the front detection distance and the rear detection distance in the same time interval exceeds a predetermined value.

Select the shortest total detected output value that appears at intervals. The total detection distance Xfi + Xri (i = 1, 2, 3,...) Corresponding to the shortest total detection output value Sfi + Sri is calculated and displayed on the display device. At this time, the notch-shaped or spike-shaped total detected output value in the time-series total detected output value may be ignored as an abnormal value.
When the total detection distance Xfi + Xri (i = 1, 2, 3,...) Exceeds a predetermined value, the remote monitoring system outputs a warning signal.
When the monitor receives the warning signal, the monitor notifies the service station accordingly.
Further, at the service station, the service person can monitor the status of the parking device in charge and see a warning signal.
As a result, the serviceman has noticed that the distance Y between the front service chain 50f and the rear service chain 50r is shortened or the distance Z between the front chain rail 60f and the rear chain rail 60r is increased. I can know.

A difference detection distance is a predetermined difference in a time-series difference detection output value Sf-Sr, which is a difference between a front detection output value output by the front proximity sensor 70f and a rear detection output value output by the rear proximity sensor and r. This corresponds to the longest difference detection output value Sfi-Sri that appears at time intervals.
