Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides an endless chain that is attached to a pair of sprocket wheels provided vertically on both sides, and connected to several dozen turntables and rotating wheels via attachments. A cage in a vertical circulation parking facility, in which a car storage cage with a tray inside is suspended and supported, and each cage is driven to circulate vertically by rotating one side of the sprocket wheel using a suitable drive device. This relates to a rotation stop device.

(Prior Art) As shown in Fig. 1, the above-mentioned type of vertical circulation parking equipment has a parking system that is stretched between a pair of upper and lower sprocket wheels 1 and 2 that are arranged opposite to each other and are provided on the entrance side and the rear side. Several cages 5 are suspended from two endless bands, such as an endless link chain 3, via attachments 4, and motors 7, brakes 8. The upper tin rocket is rotated by a drive device 11 consisting of a speed reducer 9, a machine stand 10, etc., so that each of the cages moves and circulates in the vertical direction. In this case, the endless link chain 3 It is desirable that a chain guide 12 and a guide roller 13 be installed in the cage 5 to prevent it from swinging during circulation drive.
In addition, vehicles are entered and exited by changing direction using a turntable 14 provided in front of the entrance.

However, in soft-soil parking facilities, even if a car enters the parking lot by moving forward and climbing onto the cage 5, it must exit by reversing when leaving the parking facility, which can be extremely difficult for drivers with inexperienced driving skills. .

Therefore, there is a need for a parking facility that allows parking to be entered and exited by moving forward, and for this purpose, it is necessary to turn the car on the cage that has been entered by moving forward.

For this reason, the applicant of the present invention differs from Japanese Patent Application Laid-open No. 59-220569.
, a tray consisting of a rotating stand for a rotating tray with a turntable function, a circular rail integrally formed on the upper surface of the cage member on the back surface, a group of main rollers for support, and a friction transmission means for rotating. A rotating drive mechanism and a tray rotating pedestal elevating mechanism for supporting and raising and lowering the rotating pedestal are installed, and the rotating tray is arranged to be superimposed on the cage and on which a car or the like is to be placed. A vertical circulation parking system was proposed.

That is, the turntable/swivel tray provided on the cage member is pivotally mounted on a center post and has a structure in which it can rotate around the post, and the rotation of the turntable/swivel tray is caused by the rotation of the storage cage or the cage member. This is done by a tray turning drive mechanism installed below the stop position (car loading/unloading position). Stopping and positioning of the table/swivel tray is performed by a proximity switch or limit switch installed on the fixed floor.

The sensing plate is attached to the underside of the rotating tray,
It is adapted to be adjusted to a position compatible with the proximity switch or limit switch.

However, in the above-mentioned vertical circulation type parking equipment in which the tray on which the car is placed is superimposed on the cage and is rotated, it is common for a certain amount of error to occur when the cage is stopped. For this reason, when controlling the stop of a rotating tray using a proximity switch or limit switch installed on a fixed bed, variations in rotational stopping accuracy occur due to the influence of the cage stopping position error. This will cause the problem of not stopping at the correct position. in this way.

If the error in the stop position of the rotating tray exceeds the allowable amount for use, it is normal practice to center the main body of the drive unit so that it follows the stop position of the cage, but this can result in major structural damage. This has the disadvantage that economic efficiency is reduced.

(Problems to be Solved by the Invention) The present invention provides a pusher unit with a detection arm installed on a fixed floor, on which a proximity switch or limit switch for detecting the position of the cage and a proximity switch or limit switch for stopping rotation of the rotating tray are attached. Provided is a cage rotation device that can accurately stop and position the cage and the rotating tray by connecting and connecting the switches so as to be able to freely raise and lower, and making both the switches follow the cage that has stopped circulating and the rotating tray that has stopped rotating. This is what I am trying to do.

(Means for Solving Problem c) Therefore, according to the present invention, a power cylinder and a guide cylinder with a guide groove are installed on the fixed floor on either the left or right side when viewed from the exit for one person. A guide shaft that is fitted and rotated in the guide cylinder and has a guide roller is drivingly connected to the power cylinder by a rotary joint, and a proximity switch or limit switch for detecting a cage stop position is provided at the end of the guide shaft. Also, a detection arm to which a proximity switch or limit switch for stopping rotation of the rotating tray is attached is fixed.

(Example) The apparatus of the present invention is normally used as shown in FIG. 2(a).

It is installed on the fixed floor 15 on the right side (in principle, the left side) back side when viewed from the entrance side of the vertical circulation parking facility,
Mainly, a power cylinder 17 pivotally mounted to a pair of brackets 16 provided on the floor, a guide shaft 19 that slides and rotates by fitting into a guide cylinder 18 provided on the floor, and an end of the shaft. In this case, the rod 21 of the power cylinder is drivingly connected to the guide shaft via a rotary joint 22, and the rod 21 of the power cylinder is fixedly attached to the shaft. A guide roller 2
Reference numeral 3 denotes a revolving tray 27 which fits and slides into a guide groove 26 consisting of a straight groove part 24 and a spiral groove part 25 carved in the guide cylinder, and forms a cage 5 at the free end of the detection arm and inside thereof. and a proximity switch (or limit) 29,30 for detecting the stop position which cooperates with the cage member 28.

(Function) In the above-mentioned vertical circulation type parking equipment, during the vertical circulation drive of the storage cage 5 carrying a car that has entered from the direction of the arrow as shown in Fig. 3 (a), as shown in Fig. 2 (a) As shown, by the operation of the power cylinder 17, the guide roller 23 of the guide shaft 19 fits into the guide groove 26 of the guide cylinder 1, slides in the direction of arrow A, and reaches the dotted line position.
The guide shaft rotates in the direction of arrow B shown in FIG. 2 (b),
The detection arm 20 attached to the end of the guide shaft is in a collapsed state as shown in FIG. In order to improve driving safety and parking efficiency, turn the turntable/swivel tray 27 counterclockwise.
It turns 80 degrees.

In this case, after pressing a call button (not shown) as appropriate to stop the storage cage 5, which has been circulated to the transporter position of the automobile, at a predetermined position, as described in Japanese Patent Application Laid-Open No. 59-220569.

When the rotating tray 27 is lifted upward from the cage member 28 by the tray rotating gantry lifting mechanism provided with the tray receiving roller, the fringe rollers of the tray rotating mechanism move against the lower surface of the circular rail provided on the back surface of the rotating tray. in elastic contact with.

The rotary tray rotates counterclockwise from the state shown in FIG. 3(A) due to the frictional force caused by the drive of the motor.

Next, when the rotating tray 27 rotates counterclockwise and passes over the detection arm 20, the power cylinder 17 is activated, as shown in FIG. 2(A).

The guide roller 23 shown by the dotted line is the spiral groove part 2 of the guide groove 26.
5 in the direction of the arrow C, the guide shaft 19 rotates in the direction of the arrow C, and the detection arm 2 is moved at the end point of the spiral groove.
0 is in the upright state, and subsequently, the linear groove portion 24 of the guide groove 26 is moved in the direction of the arrow E by the operation of the power cylinder, and at the solid line position, the proximity switch for detecting the stop position is moved as shown in FIG. 3 (b). The limit switch 29 comes into contact with the cage member 28 forming the cage 5, and the power cylinder is stopped and positioned.

As shown in FIG. 309, due to the rotation of the rotating tray 27,
The side surface of the rotating tray comes into contact with the rotation stop proximity switch or limit switch 30, the rotating motor is stopped, the rotating tray is positioned, and the vehicle moves forward to leave the garage in the direction of the arrow.

(Effects of the Invention) According to the present invention, the proximity switch or limit switch for detecting the stop position attached to the detection arm is positioned by following the cage or cage member that has been stopped in circulation, and the detection arm is Since the tray is made to stop when the tray rotation stop proximity switch or limit switch attached to the free end comes into contact with the rotating tray, a centering structure is required for the main body of the drive device that follows the cage stop position. Since there is no rotation, it is possible to improve economic efficiency, and there is no variation in the position at which the rotating tray stops rotating.

It is easy to adjust the position of each switch on-site, and the cage can always be stopped at a fixed position.
This eliminates the need for mid-rotation stop and corrective action, which were conventionally required, and has the advantage of eliminating time lag.
