Description

Detailed Description of the Invention This invention is mainly installed at an approach road to a sales floor, automatically opens when a person arrives at this approach road, and automatically closes after a certain period of time to close this approach road. The present invention relates to an automatic gate that prohibits exiting from this entrance road.

This type of gate is generally operated by a motor controlled by a photovoltaic circuit, for example, around one vertical axis.
It has one horizontal section that is rotated by four rotations.

According to current regulations, such games should, if the need arises, be opened from the closed position and opened for human access.
Ai-? It must be possible to get it out.

Therefore, the horizontal section of the rotating machine in an automatic game is generally controlled by the push 'F' that acts on this horizontal section. It is engaged with the vertical shaft through a spring stop adapted to prevent release of the gate in the opposite direction, unless the force exceeds a set value that can be adjusted mechanically by a spring or similar means. has been done.

It is often the case that this stop is adjusted to oppose the maximum resistance of opening the gate in the opposite direction, and prohibits people from exiting the access path, whether they like it or not. be.

If a person trying to get out of this platform applies a large force to the horizontal part 4A of the gate in order to open the gate 1, this force will cause the cage to be held by the spring stopper. If the horizontal part 11N is in contact with the gate and the length of the arm is multiplied by the length of the arm, the force is transmitted from the spring L to the drive shaft. , the gate quickly malfunctions or is destroyed.

The purpose of this invention is to eliminate these inconveniences in order to improve human safety in the event of a collapse.

In order to achieve this object, the present invention includes a substantially horizontal arm integrated with a vertical Iil+, which is installed in the approach path of the sales floor'\ and is rotatably supported by a column, and which is driven to rotate. The motor and the sales floor pass through the approach road.
516 In the automatic game 1, the motor control means is operated to move the motor λ, and the motor control means is supervised by a person or a trolley, and simultaneously controls the brake of the vertical axis. ”． This brake [depends on the vertical axis of November, January 1 hour]
To provide an automatic game (1) characterized in that the braking force is approximately zero and the braking force is made equal to a set value when the motor is stopped by a motor control means.

Therefore, according to the present invention, when the gear 1 is stopped at the position where it closes the approach path to the sales floor, a force of a predetermined magnitude is constantly applied to the drive shaft of the gear 1. The force is generated by the activation of the gear 1 drive motor.
When the gate is opened in the entry direction, it is offset, allowing people to enter the sales floor.

On the other hand, when a person attempts to exit from a fully prepared approach road, all he has to do is apply a pressing force to the gate that overcomes the braking force exerted by the brake. It is enough. This pressing force is absorbed by the brake, not by the support of the game 1.

When this brake is applied to the control means (= J force, the adjustment is 1t
Preferably, the brake is connected to I+ and released when the control means is deenergized.

This brake PJ1. (a) of the gate closing the L entryway; and (b), it may consist of one friction disc fixed to a vertical shaft forming the body and another rotating friction disc. These two discs can be fully tightened using a preset force via electromagnetic means.

Therefore, the rotation of the vertical axis when opening the game I- in the opposite direction is 11.
11, it does not mean that force is intensively transmitted to the support part of the iris.

As the torque limit jj3, it is preferable to interpose the same scale device between the vertical shaft 1 and the output shaft of the drive motor.

Hereinafter, one N, i example of the present invention will be described in detail with reference to the accompanying drawings.

The automatic gate shown in Attachment 1ifJ diagram is fixed to the floor,
It also includes a pillar (10) that rotatably supports the vertical axis U through a bearing.

A horizontal arm (16) is integrally attached to the upper end of the vertical shaft (16). It is connected to the output shaft via a torque limiter (18j).

A movable contact plate (20) is fixed to the vertical shaft (141),
A disc-shaped electromagnet L221t, which is attached to the support column 00) and passes through the vertical axis 00, is opposed to the movable contact plate (20), thereby forming an electromagnetically controlled brake. The movable contact plate (20) and the electromagnet (20) are
A friction lining is provided.

'When the electromagnet (221) is excited, the movable contact plate (221
Aspirate @ and tighten the friction lining between these two parts; then brake. When the electromagnet (221) is not energized, the clamping force (=1) on the friction lining becomes zero and the brake is released, allowing the vertical axis (+41) to rotate freely.

Since it uses an electromagnetic control type brake, the braking force that attempts to prevent the rotation of the vertical axis ([4J] when the brake is tightened can be adjusted to a value that complies with current regulations. However, during sales floor maintenance, it is difficult or impossible to change these preset values.

To open the closing position of the entrance, turn it vertically +1'll+ (+41 f, c, in the direction shown by the arrow (28) in Figure 2. Then the game The direction of approach to the sales floor (opens to the left in this direction).

The photovoltaic cell (C2) kll is provided at a constant angle fi1 with respect to the vertical axis (Hl) so as to face the one notch (2t;) when the gate is in the position to close the approach path. The photocell (C6) is rotated by an angle of 90 degrees or slightly less than 90 degrees from the vertical axis (14I) closing the approach path (S'L) in the direction of rotation indicated by the arrow C2+<l. , and is provided at an angular position facing the notch (20) of the disc C24).
