Description

[Detailed description of the invention] This invention is suitable for gate opening/closing when implemented in a gate bar opening/closing machine that is used at the entrances and exits of unmanned parking lots, railroad crossings, venues, etc. to manage the entrance and exit of cars and people. Regarding a drive device.

The opening/closing drive device used in conventional gate bar opening/closing machines starts the drive motor using an automatic or manual switch, etc., and transmits the rotational force of this motor directly or indirectly through gears to open/close the gate bar. However, there were some problems in usage and functionality, and it was necessary to take countermeasures.

For example, when the gate bar is closed, if an unscrupulous person tries to forcibly lift the gate bar to illegally enter or exit the warehouse, the gate bar may easily open and cause unauthorized access or unauthorized entry and exit. In addition, when the gate bar that operates to open and close is stopped at the open/close position, the gate bar directly hits the stopper and stops at a constant speed, so the balancing device when stopped is very large and requires bearings and transmission. There are problems such as wear and tear of parts, etc., and it has been desired to solve these problems.

The present invention was devised to solve the above-mentioned problems, and its purpose is to configure the gate bar so that once it is closed, the gate bar cannot be opened by hand unless the drive motor is driven. It is an object of the present invention to provide a gate opening/closing drive device for a parking lot, etc., in which the speed at which the gate bar opens and closes is gradually reduced from before the stopping point, so that the balance during stopping is reduced as much as possible, Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, Figure 1 shows the state where the gate bar 1 is closed, and Figure 1 shows the state where the gate bar 1 is closed.
The figure shows the state in which the gate bar 1 is open, and the plate end of the gate bar 1 is fixed to a mounting body 11, and this mounting body 11 is attached to the opening/closing machine body (shown in the figure, but the reference numeral is omitted) with a bearing ( (not shown) is fixed to one end of a rotating shaft 7 rotatably supported, and the plate end of an actuating arm 8 is fixed to the other end of this rotating shaft 7.

Reference numeral 3 denotes a connecting rod whose tip is rotatably connected to the tip of the operating arm 8 using an arm pin 8a, and the plate end of this connecting rod 3 is rotatably attached to the side surface of the peripheral edge of the toggle gear 2 using a connecting pin 2a. It is pivoted freely.

The toggle gear 2 is rotated in conjunction with a drive gear 10 of a drive motor 9 installed in the main body of the opening/closing machine,
When the toggle gear 2 is rotated in the direction of the arrow in FIG. 1, the gate bar 1 is closed as shown in the figure. Conversely, when the toggle gear 2 is rotated in the direction of the arrow in FIG.
The mechanism is such that it is operated in the open position as shown in the figure.

Note that 5 is a gear shaft of the toggle gear 2.

Next, in Fig. 1, 4 hits the connecting pin 2a of the toggle gear 2 which is being rotated in the direction of the arrow (counterclockwise rotation direction), and the rotation of the toggle gear 2 is stopped at the position where the gate par 1 is closed. , the centers of the connecting pin 2a and the arm pin 8a are located on a vertical line (indicated by line A-B in FIG. 1) passing through the center of the toggle gear shaft 5, and the upper stopper is stopped. , when the closing movement of the gate par 1 is stopped, the connecting rod 3 is located at a completely upright dead point,
Even if you try to push up the gate par 1 by hand, it is completely locked and cannot be opened, and the gate par 1 can only be opened when the drive motor 9 is started and the toggle gear 2 is rotated clockwise in Fig. 1. I'm confused by the structure.

Further, in Fig. 2, 6 is a lower stopper that hits the connecting pin 2a and stops the rotation of the toggle gear 2 at the open position of the gate par 1, and these upper and lower stoppers 4 and 6 are both operated by the opening/closing device. It is attached to the main body side.

Since the gate opening/closing drive device according to the present invention has the configuration as described above, the gate opening/closing drive device according to the present invention has the structure as described above.
In order to open and move, it is sufficient to start the drive motor 9 in normal rotation and rotate the toggle gear 2 in the clockwise direction in the drawing, and also,
In order to close the gate par 1 opened as shown in FIG. 2 by the rotation of the toggle gear 2, the drive motor 9 is started in reverse and the toggle gear 2 is rotated counterclockwise in the drawing.

When the toggle gear 2 rotates in the forward and reverse directions as described above, the connecting rod 3 moves up and down the operating arm 8 to open and close the gate par 1, and this opening and closing operation is performed when the connecting pin 2a is locked to the upper and lower stoppers 4 and 6. However, in the present invention, the opening/closing speed of the gate par 1 is controlled to be approximately 1/4 of the maximum speed from approximately 40 degrees before the stopping position of the connecting pin 2a by the action of the toggle gear 2 and the connecting rod 3. It can be decelerated to 1/7 before 30 degrees, making gate par 1.
It is possible to significantly reduce the balance applied to the upper and lower stoppers 4 and 6, which are the opening/closing stopping points.

Therefore, according to the gate opening/closing drive device of the present invention, once the gate is closed, it is locked in the closed state by the connecting rod located at the tee point, and cannot be opened unless the drive motor is started. In addition, since the opening/closing speed of the gate par is gradually reduced from just before the stopping point, the balance on bearings and transmission members, etc. It has the advantage of protecting the equipment from wear and tear and minimizing breakdowns, and combined with the fact that it has a simple configuration and is easy to implement, it can be implemented in various gate bar opening/closing machines. suitable for
