The rotation power of the speed reducer 37 is transmitted to the lower rotation shaft 33 by a structure directly coupled to the hollow shaft of the speed reducer 37 and the lower rotation shaft 33.

In this case, it is preferable that the driving motor 35 and the speed reducer 37 are fixed to the front frame 21 in a state where the driving motor 35 and the speed reducer 37 are vertically disposed. This is because the lubricating oil leaking from the speed reducer 37 flows into the driving motor 35 Thereby preventing a malfunction from occurring.

The link unit 40 is configured to swing the door plate 13 by the rotational force transmitted through the driving unit 30 and to rotate in a state in which the posture is maintained while the door plate 13 is rotated. 31) and a lower rotary shaft (33), which are disposed on the upper drive arm (41), the lower drive arm (43) and the rear frame (23) An upper end arm 45 and a lower end arm 47 both of which are hingedly fixed to the coupling hole 15 of the door plate 13 in the fixed state and both ends of the upper and lower ends of the upper and lower drive arms 41, And a connecting arm 49 rotatably fixed to the other end of the connecting rod 43.

The upper driving arm 41 and the lower driving arm 43 are formed of link members having the same link length and are fastened to the upper rotation shaft 31 and the lower rotation shaft 33 at the same positions on both ends in the longitudinal direction, And a hinge member to be fixed to the connection arm 49. The hinge member is fixed to the upper rotation shaft 31 and the lower rotation shaft 33 at the same inclination angle with respect to the bottom surface.

The link length means a length between hinge connection points and does not mean the entire length.

The upper longitudinal arm 45 and the lower longitudinal arm 47 are also made of link members having the same link length and are fastened to the upper rotary shaft 31 and the lower rotary shaft 33 at the same positions on both ends in the longitudinal direction. And a hinge member to be fixed to the coupling hole 15. The hinge member is fixed to the upper rotation shaft 31 and the lower rotation shaft 33 at the same inclination angle with respect to the bottom surface.

The connection arm 49 transmits part of the rotational force transmitted to the lower rotary shaft 33 through the hollow shaft of the speed reducer 37 to the upper rotary shaft 31.

Therefore, when the drive arms 41 and 43 have the same inclination angle with respect to the bottom surface and the connecting arms 49 are hinged to the same length points from the rotating shafts 31 and 33, When the driving motor 35 is rotated, the door plate 13 maintains the set posture by hinging the coupling springs 15 at the same length from the rotary shafts 31 and 33 with the same inclination angle with respect to the floor surface Swinging state.

4 is a front view showing the opening and closing process of the automatic gate for a ticket gate according to the present invention. 3 to 4, the control unit controls the swing rotation of the door plate 13, and includes a control circuit and an encoder 51 installed in the drive motor 35. [

A spring fixing member 53d is formed on the upper driving arm 41 and an elastic supporting member 53 is connected between the spring fixing member 53d and the front frame 21. [

A stopper 55 is horizontally disposed on the lower portion of the front frame 21 and a locking protrusion 57 engaged with the stopper 55 protrudes from a side surface of the lower driving arm 43, Thereby preventing abnormal rotation.

As shown in FIG. 4, the door plate 13 has an arc-shaped locus that is located at top dead center points A and A 'when the door is opened and closed. In order to achieve stable swing rotation, , It is required that the rotational speed gradually decelerates as it approaches the top dead center point (A, A ') so that an excessive load is applied to all the components.

The control circuit controls the acceleration and deceleration of the driving motor 35 according to the position of the door plate 13 by calculating the speed related sensing signal of the driving motor 35 generated by the encoder 51 .

The elastic supporter 53 has a structure for relieving an impact by canceling a moment due to the weight of the door plate 13 at the top dead center A and A 'and is provided at a position below a vertical line C passing through the upper rotary shaft 31 A spring fixing piece 53d protruding from one end of the lower fixing pin 53b while being fixed to the upper driving arm 41 and a spring fixing piece 53d provided on the spring fixing piece 53d, An upper fixing pin 53c provided at a position having a phase difference of 180 degrees from the hinge member of the upper longitudinal arm 45, that is, on the longitudinal direction of the spring fixing piece 53d, And a spring 53a fixed to the upper fixing pin 53c.

Particularly, the upper driving arm 41 extends transversely to the longitudinal direction of the spring fixing piece 53d in the direction of 80 ° to 100 ° and is connected to the connecting arm 49, It is preferable that a moment opposite to the moment due to the self weight of the door plate 13 is applied by the connected spring 53a.

More specifically, the spring fixing piece 53d is disposed on the opposite line from the hinge member of the upper vertical arm 45 with respect to the upper rotary shaft 31 so that the spring fixing piece 53d acts on the upper rotary shaft 31 by the elastic force of the spring 53a Of the door plate 13 is always opposite to the moment due to the weight of the door plate 13 during swing rotation so that the impact caused by the inertia resistance of the door plate 13 which is stopped at the top dead center points A and A ' do.

In this case, the spring 53a applies a constant current to both ends of the spring 53a so as to be heated to about 100 ° C in a state where the spring 53a is stretched to suppress the generation of noise due to the impact caused by the elastic deformation And coating an epoxy layer on the surface of the spring 53a by powder coating.

When the door plate 13 rotates out of range due to a malfunction of the control circuit or the encoder 51, the stopper 57 and the stopper 57 are engaged with the stopper 55, Thereby preventing excessive rotation of the plate 13.

In this case, the stopper 55 is a modification of the stopper 55. The stopper 55 includes a projection accommodating groove 55a for partially accommodating the engaging projection 57, And a buffer pad 55c formed on the bottom of the buffer pad 55c.

In the present invention, the width of the enclosure 11 of the gate main body 10 may differ depending on the gate installation site, which can be easily adjusted by adjusting the setting range for the rotation swing of the control circuit, The locking protrusion 57 adjusts the fixing position in the longitudinal direction of the lower vertical arm 47 to prevent the locking of the stopper 55 and the locking protrusion 57 from improper engagement.

Meanwhile, in another embodiment of the present invention, the door plate 13 can be opened / closed by reversing the door through a simple design change.

6, a door guide 59 for supporting the lower end of the door plate 13 is installed at a lower portion of the rear frame 23, and an upper end arm 45 and a lower end arm 47, If the slot 15a corresponding to the top dead center A and the top dead center B of the bottom dead center B is formed at the binding site 15 at which the hinge member a of the top dead center B is engaged, The door plate 13 does not swing through the hinge member a and the slot 15a which are constrained by the connection arm 49 and the relative movement of the lower arm arm 45 and the lower arm arm 47, It moves forward / backward without bottoming point and opens / closes Kate exit.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
