Description

Dual ticketing prevention device of a pass ticket generator {APPARATUS FOR PREVENTING DOUBLE ISSUING OF PASSAGE PUBLISHER}

The present invention relates to a dual ticketing prevention device of a pass ticket generator, and more particularly, to a dual ticketing prevention device of a pass ticket generator that can prevent the dual ticketing by passing only one pass, even if two passes are supplied. .

Generally, in a closed toll highway in which an entrance toll gate and an exit toll gate of a highway are installed, a ticket issuing machine for issuing a ticket for the purpose of collecting a fee according to the highway traffic is provided at the entrance toll gate. A toll gate is installed at the toll gate to read the toll collection information recorded on the toll and collect the toll.

1 is a view showing the inside of the pass ticket issuer according to the prior art.

As shown in FIG. 1, the pass ticket issuing machine according to the related art includes a housing 100 in which components are mounted therein, a pass storage unit 110 installed upright on a lower side of the housing 100, and a pass storage unit ( It is roughly divided into a pass right transfer unit 120 for drawing and transferring a right of passage (not shown) from 110 and a ticketing unit 130 for issuing the transferred right.

The pass ticket machine is provided with a pass cassette 112 in which the pass 140 is stored in the pass storage unit 110, and the pass cassette is located at a position adjacent to the pass cassette 112 by a rotational force of a driving motor (not shown). The withdrawal roller 160 is rotatably provided so that the right of passage in 112 may be withdrawn. In addition, the feed roller 170 is rotatably positioned at a position adjacent to the take-out roller 160, and the feed roller 170 is connected to the take-out roller 160 by the timing belt 180 to take out the roller 160. It is comprised so that the passage right 140 withdraw | derived by it may be conveyed.

In such a prior art automatic ticket issuing machine, the ticket is transferred to the transfer part by detecting a vehicle type entering the toll gate at the entrance while the ticket is drawn out of the ticket cassette 112 by a drawing device (not shown). It is transferred and ticketed.

However, in the conventional ticket issuing machine, when the ticket stored in the ticket cassette is withdrawn in the overlapped state and is transferred to the conveying unit, two tickets are not provided to detect the overlapped state of the ticket or to separate the overlapped ticket. There was a problem that the ticket was incorrectly issued with overlapping passes.

This problem could be somewhat resolved by the Republic of Korea Patent No. 10-0263335 (notice date: October 02, 2000).

That is, as shown in FIGS. 2 and 3, the separator roller 190 is installed at a predetermined distance from the conveying roller 170, and the separator roller 190 is configured as a pass right from the pass cassette cassette 112. 140) is overlapped and configured to prevent two or more wrong fetches. In other words, the separator roller 190 is connected to the rotary shaft 191a of the motor 191 to be rotated by the operation of the motor 191, and in particular, the torque limiter 192 is connected to the rotary shaft 191a of the motor 191. When the rotation load is applied to the separator roller 190 more than specified, the joint portion for transmitting the rotational force slips or falls so that the rotational force of the motor 191 is not transmitted to the separator roller 190. As a result, the separator roller 190 stops rotation when the pass is overlapped.

In the conventional art of this structure, when the pass ticket 140 is abnormally overlapped and two or more sheets are incorrectly drawn out by the withdrawal roller 160, the overlapping pass ticket 140 is disposed between the feed roller 170 and the separator roller 190. Inflow to the conveying path formed in the feed roller 170 continues to rotate in a clockwise direction, the separator roller 190 is stopped by receiving the rotational force of the motor 191 by the torque limiter, accordingly The overlapped pass 140, ie, the lower pass 144, receives the force to move forward by the transfer roller 170, and the upper pass 142 receives the force to stop by the separator roller 190. In addition, the separation force of the transfer roller 170 and the separator roller 190 is greater than the overlapping frictional force of the pass 140 so that the pass 140 is separated into an upper pass 142 and a lower pass 144. That is, the lower right of the pass 140, 144 is transferred to the transfer unit 120 issued through the ticketing unit 130, and remains after the transfer and ticketing of the lower pass (144) by the pass detection sensor 200 is confirmed. The upper pass right 142 was then transferred to the transfer unit 120 is issued from the ticketing unit 130.

However, the pass ticket issuing machine according to the related art has a problem in that it is difficult to separate the overlapping pass when the torque limiter malfunctions.

In addition, when the surface of the separator roller 190 is worn, even if the torque limiter does not malfunction, there is a problem in that overlapping passage passes through a larger distance between the feed rollers 170.

Referring to the operation of the dual ticketing prevention device of the pass ticket generator according to the present invention configured as described above based on Figure 9a, 9b, 9c, 9d, 9e as follows.

When the right of travel is transferred to the guide unit 60 by the pickup roller 20, if two passes are transported as shown in FIG. 9A, the two passes are entered between the upper guide plate 62 and the lower guide plate 64. do.

At this time, of the two passes entering between the upper guide plate 62 and the lower guide plate 64, the right of contact with the lower guide plate 64 is guided to the guide inclined portion 82 as shown in Figs. 9B, 9C, and 9D. It is transferred between the feed roller 30 and the idle roller 40 through a gap T formed at the end of the jaw 74A and the end of the gap forming block 80 and then transferred to the next step.

In this way, when one pass passes the gap T formed with the thickness of one pass, the front end portion of the other pass that enters between the upper guide plate 62 and the lower guide plate 64 in contact with the upper guide plate 62 is spaced. The movement stops by being caught by the locking jaw 74A of the adjustment block 74 of the adjustment block 70.

Thus, the interval adjusting block 70 and the interval forming block 80 can pass only one pass even if two passes enter.

On the other hand, since the pick-up roller 20 keeps pushing the remaining passage right that has been caught by the stopping jaw 74A, the gap adjusting block 70 and the gap forming block 80 are caught by the gap adjusting block 70 by the traveling force of the pass. The jaw 74A is pushed. The gap adjustment block 70 is rotated by a predetermined angle in the counterclockwise direction while overcoming the elasticity of the first elastic body 92. In this operation, the upper shaft 76 is rotatably installed about the lower shaft 84 in a state in which the upper shaft 76 and the lower shaft 84 are integrated, and the gap adjusting block 70 is formed of the first elastic body ( 92 and the second elastic body 94 are elastically supported. As the gap adjusting block 70 is rotated at a predetermined angle in the counterclockwise direction while overcoming the elasticity of the first elastic body 92, the locking jaw 74A forms an obtuse angle with the guide surface 62B, thereby causing the locking jaw to fall. The rest of the pass that was taken at 74A is entered and transported at interval T.

After the passage passes, the space adjusting block 70 and the space forming block 80 are returned to their original state by the elasticity of the first elastic body 92 and the second elastic body 94, and thus the locking jaw 74A and the guide surface. 62B again maintains a right angle.

In this way, the gap adjusting block 70 and the gap forming block 80 form an interval T which is not arbitrarily variable, and the gap is formed by the block flow means 90 while forming an interval T that is not variable. By changing the position of T), it is possible to effectively pass a double pass for each pass.
