Abstract

The present invention discloses an improved apparatus for driving a flap door in a flap type automatic dog tag.

In the conventional flap drive, the driving motor is responsible for driving in both opening and closing directions, so that the rapid operation is difficult and the structure is complicated, but the impact force applied to the flap door is directly transmitted to the drive motor and the electric system to damage the device and cause a safety accident. There was a fear of causing.

In the present invention, the flap door is elastically biased to one side so that the driving motor is responsible only for driving in the other direction, and the movement of the flap door is elastically limited at the other end to enable inexpensive configuration and absorb the impact force efficiently. To improve the durability and prevent accidents.

Description

Flap drive device of flap type automatic dog ticketing machine

The present invention relates to a flap driving apparatus used for a flap type automatic dog marking machine, particularly a flap for an automatic dog marking machine.

Automatic kennels are devices used to control traffic between free and paid areas by counting and counting tickets, and currently, mainly tickets for subways and trains, and some amusement parks. It is used to recount tickets of the tickets (hereafter exemplified by comparing them with the subway and its tickets).

Conventionally, the method mainly used as the automatic dog tag is a turret or turn-table (hereinafter referred to as a turret method), which allows a plurality of limit bars arranged on one turret. The passer who passes through it rotates one by one, and when the passer who does not have a ticket wants to pass, the brake is applied to the turret to block the passage.

This turret type automatic dog ticketing machine has the advantage of simple mechanical structure due to the small number of driving parts, but because of its structure, it can pass only one direction at a time, so the processing speed is low, so rush hour, etc. In the case of a large number of passers-by, the automatic ticketing system itself forms a bottleneck in the passage, which is a major obstacle to the transportation capacity of the subway, and there is a problem that a separate ticketing system must be installed depending on the passing direction. In addition, there was a problem that it was difficult for the elderly to pass because of the considerable manpower required to pass, and apparently it was possible to determine whether the pass was allowed, so that the passer who was allowed to pass in case the ticket counter recognized the ticket incorrectly. There was a risk of safety accidents such as injuries due to the shock to the passersby.

In order to solve the problem of the turret method, a flap type automatic dog ticketing machine related to the present invention has appeared, which has a flap door that is opened and closed with a normal or closed state for a passage. Can be set arbitrarily. In other words, in the time zone where many passers pass such as rush hour, it is set to be always open and prevented only when the unacceptable passers are recognized. In other times, it is set to be always closed and the flap door is opened only when the passers are recognized. .

In this way, the flap type automatic dog ticketing system not only causes bottlenecks in traffic, but also handles two or more passers at the same time, achieving a processing speed of more than 60 people per minute, which is several times the turret type. In addition, it is possible to handle in both directions, so in a place or time zone where traffic is low, one ticket can handle the passers in both directions, which can reduce the required number.

Due to these advantages, despite the structural complexity of the flap type automatic dog ticketing system, the overall economic efficiency is superior to that of the turret type, and the newly installed automatic dog tagging machines are generally dominated by the flap type.

Figure 1 shows the overall configuration of such a flap type automatic dog ticket, the front and rear of the front and rear of the main body (M), which is provided with a ticket transfer machine not shown, respectively, the left and right opening and closing with respect to the main body (M) A pair of flap doors (D) are provided, and a side bar (B) having a sensor array (S) for recognizing a passer is provided on an upper portion of the main body (M). These dog tags are installed on the left and right of the passage so that the N dog marks constitute (N-1) passages.

FIG. 2 shows a flap driving device which is installed at the front and rear ends of the main body M in such an automatic dog tag, and opens and drives a pair of flap doors D on both sides thereof. It is partly used in Korea.

In FIG. 2, a pair of flap doors D are hinged to the hinge axis 107 on the left and right sides of the drive body 101 and a pair of drives to drive each flap door D on the right side of the drawing. The motor 102 is provided. The drive motor 102 has a drive pulley 103 arranged in a staggered structure staggered with each other to reduce the width of the drive body 101 and the dog mark body M, and coupled to the drive shaft. The cam pulley 104 connected by the hinge shaft 107 of each flap door D and the link 105 is electrically driven by an electric belt 106 such as a timing belt. Combined.

Such a driving device rotates the cam pulley 104 through the driving pulley 103 and the electric belt 106 when the driving motor 102 rotates by a predetermined angle according to a command of a controller (not shown). Accordingly, the flap door D rotates by opening and closing the passage by the rotation of the link 105 to control the passer-by.

In such a conventional drive device, the drive motor 102 is composed of an AC brake motor provided with an electromagnetic brake. In the conventional flap drive device, although the AC motor can only be rotated in one direction, the drive motor 102 is driven. The motor 102 should be responsible for both opening and closing the flap door D. In this bidirectional drive, the flap door D is closed when the drive motor 102 rotates the cam pulley 104 180 degrees in the dotted line in the solid state of FIG. 2 and is opened when the drive motor 102 is rotated 180 degrees in the same direction. Is done in such a way that

Accordingly, since the drive motor 102 must be continuously operated, particularly in rush hour, the power consumption is not only large, but also the opening and closing of the flap door D is not fast, so there is a problem that it is difficult to control the appropriate passer-by.

In addition, since the driving device rotates the flap door D in both directions by the driving motor 102 rotating in one direction, either the open or closed state is maintained by the electromagnetic brake provided in the driving motor 102. This leads to very large problems during power outages. For example, when the flap door (D) is a power failure in the closed state, the electronic brake is in a locked state, so it is difficult for a passer-by to pass through it, and there is a risk of a safety accident. 102) there is a risk of damage.

That is, the impact force exerted on the flap door D, which is passed through by the intentional or negligence, is transmitted directly to the brake, and the impact force applied to the flap door D while the brake is released, for example, during opening or closing, There is a risk of being directly transmitted to the drive motor 102 to damage each. In addition, when opening from the closed state, the flap door (D) at the end of the open side collides with the drive unit body 101 to apply an impact force to the drive motor (102).

As a result, in the conventional structure, the structure in which the link 105 of the hinge shaft 107 is connected to the cam pulley 104 through the long transmission belt 106 instead of being directly connected to the driving pulley 103 is basically used. In order to protect the expensive drive motor 102 can be seen.

In other words, the configuration of FIG. 2 is intended to protect the drive motor 102 and its electric system by indirectly transmitting the impact force by the electric belt 106, but the electric belt 106 has the timing as described above. When the belt is composed of slip, the slip is very small, and there is little effect of alleviating the impact force. On the contrary, when the flat belt or the V belt is used, the slip is excessive and the flap door D cannot be opened and closed correctly. A problem arises.

In view of such a conventional problem, the object of the present invention is to open and close quickly, efficiently damping the impact force transmitted from the flap door to prevent damage to the drive motor and its electric system, and further simplify the overall structure It is to provide a flap drive that can be.

* Explanation of symbols for main parts of the drawings

D: flap door 1: main body (of flap drive)

2: drive motor 3: drive pulley (pulley)

4: cam pulley 5: link

6: electric belt 7: hinge shaft (of flap door)

8: torsion spring (elastic bias means)

9: stopper (elastic stopper means)

The flap drive device according to the present invention for achieving the above object is an elastic bias means for elastically biasing the hinge axis of the flap door or its link to the closed or open side, and the opposite side of the bias direction of the elastic bias means. And an elastic stopper means for elastically restricting the movement of the hinge shaft or its link at the open or closed end.

According to this configuration, the flap door is always kept in either the closed or open state, and is switched to the open or closed state in the opposite direction only when the drive motor is driven. The flap door can be opened and closed. Since the flap door is in contact with the elastic stopper means at the end of the transition of the open or closed state, the impact force is attenuated so that no impact force is generated on the drive motor and its electric system. The biasing means immediately returns to the closed or open state of the windmill which is always in the state without driving the driving motor.

In addition, since the brake does not need to be applied in the always-on state of the elastic bias side, there is no fear of damage or safety accident in case of power failure.

Accordingly, the present invention enables fast and economical driving of the flap door, protection of passers and devices in case of power failure, and the impact force at the time of opening and closing is effectively attenuated to provide a driving device with high durability and simple structure. .

EXAMPLE

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 (a) and 3 (b) show the closed state and the open state of the drive device of the present invention, respectively. In this embodiment, the bias direction of the elastic bias means, that is, the similar state of the flap door D is It is closed. On the right side of the drawing of the drive body 1, a pair of drive motors 2 driving each flap door D in only one direction of an open or closed state (in this embodiment, an open direction) is preferable. The drive pulleys 3, which are arranged in a staggered configuration and coupled to the drive shafts of the respective drive motors 2, are respectively connected to the cam pulleys 4 to which the links 5 of the hinge shafts 7 of the flap doors D are connected. It is electrically coupled to the electric belt (6).

In the illustrated embodiment, the link 5 of the hinge shaft 7 is developed at an angle of about 60 °, preferably with the flap door D not closed vertically, but rather in the forward direction of the passage. This is a preferred configuration to prevent shock and subsequent safety accidents caused by the closing of the flap door (D) as soon as the passer is allowed to pass through the passage, and the flap door (D) completely blocks the passer. Instead, it indicates to the passer that it is not allowed and calls the manager through a separate alarm.

Here, the hinge shaft 7 of the flap door D (in the link 5 coupled thereto as necessary) is provided with a torsion spring 8 (not shown in the third (a) diagram as a resilient biasing means and the third (b). ) Is coupled to the flap door D so that the hinge shaft 7 is elastically biased to the open state of FIG. 3 (a).

Accordingly, since the drive motor 2 only needs to be driven in the direction when the flap door D is kept in the normally closed state, the drive motor 2 only needs to be driven in one direction even if the drive motor 2 is configured as a conventional AC brake motor. The flap door (D) can be opened and closed quickly even by electric power, so that the appropriate passer can be controlled.

On the other hand, the stopper 9 is provided at the end opposite to the ordinary state, that is, at the open end, as an elastic stopper means for elastically restricting rotation of the hinge shaft 7 or its link 5. The stopper 9 is in the form of a roller, the middle of which is hinged to the main body 1 and one end of the lever 10 to be in contact with the link 5 when it reaches the open end. And a tension spring (12) coupled to the head (11) and the end of the lever (10) opposite the head (11) to provide an elastic contact force to the head (11).

Accordingly, the end portion of the link 5 positioned on the right side of the cam pulley 4 in the normally closed state of FIG. 3 (a) is rotated by the cam pulley 4 by the rotation of the drive motor 2 to the left of the drawing. When it reaches, the end of the link 5 comes into contact with the head 11 of the stopper 9 so that the impact force is elastically absorbed by the elastic force of the tension spring 12 and is switched to the open state of FIG. 3 (b). .

In the open state of FIG. 3 (b), when the drive motor 2 stops providing the driving force to the open side, the flap door D tries to return to the closed side by the elastic biasing force of the torsion spring 8, It is necessary. The separate brake means is not shown in this embodiment because it is assumed that the drive motor 2 is composed of an AC brake motor incorporating its own electromagnetic brake as described above.

Meanwhile, in the closed state of FIG. 3 (a), since the flap door D is elastically biased toward the closed side, the flap door D can be kept closed even without applying a brake, so that the passer is placed on the flap door D. The external force that collides or tries to forcibly open it is transmitted to the torsion spring 8 to be elastically absorbed, so that it does not affect the driving motor 2 and its electric system at all, and there is no damage to the driving device. The transmitted impact force is also greatly reduced elastically so that there is no possibility of a safety accident.

In particular, even in the event that the capacitive lamp drive device cannot be operated while the flap door D is closed, the passer can open the flap door D only by applying a force greater than the elastic biasing force of the torsion spring 8. Therefore, the problem of safety accident or device damage does not occur.

On the other hand, the flap door D, which is opened in the state of FIG. 3 (b) by the rotational drive of the drive motor 2, can be opened without impact since the link 5 is elastically contacted with the stopper 9 at the open end. It can be kept open by a built-in or separate brake, and upon release of the brake it is immediately returned to the closed state of FIG. 3 (a) by the elastic restoring force of the torsion spring 8. Accordingly, it is possible to quickly control the unacceptable passer, in this case, even if the passer collides with the flap door (D), it is an elastic force, not by the forced mechanical force of the drive motor 102 as in the prior art, and moreover the flap door (D). ) Is closed at about 60 degrees instead of 90 degrees, so the impact force is small and there is little possibility of a safety accident.

(In the above description, the closed state of the flap door (D) is described as a normal state, but it refers to a state of returning without applying an external force, and in the actual use of the automatic stopper with the drive device of the present invention, the operator opens or closes it). Please note that any state of can be set and operated as required at any time.)

Since the external impact force is hardly transmitted to the driving motor 2 and the electric system according to the characteristic configuration of the present invention as described above, even if the link 5 of the hinge shaft 7 is directly connected to the driving pulley 3, there is no problem. Will not occur.

4 shows such a direct connection, in which a link 5 coupled to the hinge shaft 7 of the flap door D is coupled directly to the drive pulley 3 instead of a separate cam pulley 4. (In this embodiment, since there is no driven pulley such as a cam pulley, the term driving loose is not appropriate, but the same name is used for uniformity of terms with the embodiments of FIGS. 3 (a) and 3 (b). Shall be)

Accordingly, since the cam pulley 4 and its supporting shaft do not need to be provided, the structure of the driving device is simplified, and the required length of the main body 1 is significantly shortened, thereby enabling the construction of a compact driving device. . In this way, even when the link 5 is directly connected to the driving pulley 3, the impact force of the flap door D is attenuated by the twisted spring 8 and the stopper 9, so that the driving motor 2 has little effect. There will be no strain on the operation at all.

In the embodiment of FIG. 4, the relative length difference between the two links 5 is directly connected to the end of the link 5 of each flap door D to the drive pulley 3 of the two alternatingly arranged drive motors 2. Becomes large. In order to reduce the length difference between the links 5, in the embodiment of FIG. 4, the lower portion of the driving pulley 3 in which the tension spring 12 of the stopper 9 of the long link 5 is coupled to the short link 5. In FIG. 4, for convenience of illustration, the tension spring 12 is shown on the drive pulley 3, so that the structure supported on the main body 1 of the pulley 3 is selected. This structure has the advantage of reducing the length difference between the two links 5 and further shortening the required length of the main body 1.

Although the flap doors D are shown as synchronously acting in the city of FIGS. 3 and 4 for convenience of illustration, the flap doors D are used to control the respective passages on both sides of the main body 1 at all times. The states are identical to each other, but it will be obvious that the switching operation to the open or closed is made independently of each other by a separate drive motor 2.

As described above, in the present design, the elastically biased flap door (D) in one always state allows the drive motor to be in charge of only one direction switching drive, thereby enabling rapid passage control with low power consumption. The elastic stopper means can effectively block the impact force applied to the drive motor 2 and its electric system, and at the same time reduce the impact on the passer-by. Accordingly, the overall structure of the drive device can be simplified, and the present invention has a very good effect of providing a flap driving device that is small in size and simple in structure, low in manufacturing cost, and improved in durability and safety to ensure long life and safe operation. .
