BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ticket separating / conveying mechanism which separates and conveys a plurality of tickets inserted in an overlapping state.

[0002]

2. Description of the Related Art Conventionally, as a ticket separating / conveying mechanism, a separating mechanism incorporated into an automatic ticket gate installed at a station ticket gate of transportation such as a railway is known. As an automatic ticket gate apparatus, an automatic ticket gate apparatus of a type that allows a plurality of tickets to be piled up and put together at a time has become popular in recent years. In this type of automatic ticket gate, a separating mechanism provided immediately after the slot makes it possible to transfer a plurality of tickets that have been batch-inserted through the slot.
The sheets are separated one by one and transported to the subsequent processing unit.

The separating mechanism has a pair of rollers, that is, a feed roller and a separating roller, which are opposed to each other with a certain gap therebetween. The gap between the rollers is adjusted to a value such that only one ticket can be passed through the transportation path. Then, by rotating the feed roller located below the transport path in the forward direction along the transport direction of the ticket, and rotating the separation roller located above the transport path in the opposite direction to the transport direction of the ticket, A plurality of tickets that have been transported via the transport path are separated one by one.

[0004]

However, since the feed roller and the separation roller are rubber rollers, they thermally expand with time and the gap between the rollers becomes narrow. In this way, when the gap between the rollers becomes narrow, it becomes difficult for the ticket to pass through the gap, the separating performance of the ticket deteriorates, and problems such as ticket jamming occur.

In order to solve this kind of problem, in the conventional separating mechanism, when the ticket cannot be separated, the retry process is performed in which the ticket is temporarily returned in the opposite direction and the separating operation is performed again. However, even if the retry process is performed with the gap between the rollers narrowed due to thermal expansion, the tickets cannot be separated well, and the friction of the rollers scratches the surface of the tickets and the friction heat This has caused a problem that the passenger ticket is undesirably heat-sensitive.

The present invention has been made in view of the above points, and an object thereof is to provide a ticket separating / conveying mechanism capable of surely separating and transferring a plurality of stacked tickets. .

Each of the sensors 30 to 43 has a light emitting unit and a light receiving unit sandwiching the transportation path, and detects the passage of the ticket by blocking the optical axis of the ticket conveyed through the transportation path extending between them. To do. That is, when the ticket is inside the separating mechanism 100, at least one of the sensors 30 to 43 can detect the ticket.

The sensors 30 to 43 are the smallest at the target position with respect to the center line of the conveyance path so that even the ticket having the smallest width among the tickets that can be handled by the automatic ticket gate apparatus can be detected. Two pairs are provided at positions spaced apart in the front-rear direction of the device so that the respective optical axes pass through positions narrower than the width of the train ticket.

Specifically, two sets of sensors 30 and 31 for detecting that a ticket has been inserted through the slot 1.

One is provided. That is, the two thickness detection sensors 6 can detect the thicknesses of all sizes of tickets.

FIG. 3 schematically shows the separation roller 17 and the feed roller 16 described above. In addition, here, the state where the two tickets P1 and P2 are overlapped and conveyed is illustrated.

Separation roller 17 and feed roller 16
Are both composed of rubber rollers having a relatively high friction coefficient. That is, if the friction coefficient between the separating roller 17 and the feed roller 16 and the boarding tickets P1 and P2 is μ1, and the friction coefficient between the overlapping boarding tickets P1 and P2 is μ2, the relationship of μ2 <μ1 is established. .

The separating roller 17 and the feed roller 1
6 are arranged to face each other with a gap T2 (mm) therebetween. That is, the separation roller 17
Is pressed against the feed roller 16 by the spring S with a tension F1 (g weight), and is locked at a position separated from the feed roller 16 by a gap T2 (mm) by a gap forming mechanism described later.

The gap T2 (mm) is T3 ≦ T2 ≦ 2 × with respect to the thickness T3 (mm) of the ticket P shown in FIG.
The relationship of T3 is satisfied. That is, the rollers 16, 17
The gap T2 (mm) between them is set to an interval in which one ticket can pass and two or more tickets cannot pass.

That is, one ticket is separated by the separating roller 17.
When passing through the gap between the feed roller 16 and the feed roller 16, tension from the separating roller 17 is not applied to the ticket, and a plurality of tickets in an overlapping state are inserted between the rollers 16 and 17. Only at a certain time, a constant tension F1 (g weight) is applied to the ticket.

The separating roller 17 is composed of the rollers 16, 1
When passing one ticket in the gap between the seven, it rotates in the forward direction along the transportation direction of the ticket, and when passing a plurality of overlapping tickets, the transportation direction of the ticket It is controlled to rotate in the opposite direction, that is, in the direction of the arrow in the figure. It should be noted that the feed roller 16 rotates normally in the direction of sending out the ticket, that is, in the direction of the arrow in the figure, when sending out the ticket regardless of the number of tickets.

In this way, when carrying one ticket,
By controlling the separation roller 17 to rotate in the forward direction, even if the ticket is inserted in a bent state, a problem such as a jam of the ticket may occur near the separation roller 17. It can be prevented. In addition, when separating a plurality of overlapping tickets, the feed roller 1
Only the lowermost ticket contacting 6 is allowed to pass through the gap and conveyed in the forward direction, and the other tickets are stopped in place by the separating roller 17 rotating in the reverse direction. At this time, since the friction coefficient μ1 between each of the rollers 16 and 17 and the ticket is larger than the friction coefficient μ2 between the tickets, the tickets are slipped and the plurality of overlapping tickets are separated.

For example, in the case of separating two overlapping tickets P1 and P2 as shown in FIG. 3, the feed roller 16 is used.
F3 = F1μ1−F1μ2, where F3 (g weight) is the force applied to the lower ticket P1 sent in the forward direction by
And the upper ticket P2 separated by the separation roller 17
If F4 (g weight) is applied in the opposite direction to F, F4 = F
It becomes 1 μ1-F1 μ2. That is, F3 = F4> 0 (μ1
> Μ2), the lower ticket P1 is sent out by the rotation of the feed roller 16, and the upper ticket P2 is separated by the reverse rotation of the separation roller 17.

Next, the transportation speed of the ticket will be considered.

In order to process as many tickets as possible within a unit time, it is desirable that the tickets inserted into the automatic ticket gate are transported as fast as possible and processed at high speed.
In response to such a demand for shortening the processing time, generally, an automatic ticket gate conveys a ticket at an extremely high speed. Therefore, the separating mechanism 100 is also required to convey the tickets at high speed to separate them. However, as the processing speed increases, the ticket, the separation roller 17 and the feed roller 1
The frictional force between 6 and 6 is reduced, and the occurrence of separation errors and double feeding increases.

Therefore, the carrying speed (first speed) when one ticket is inserted is V1 (mm / s), and the carrying speed (second speed) when a plurality of tickets are stacked and inserted. ) To V
It is adapted to switch to V2 (mm / s) which is slower than 1.
Thereby, when separating a plurality of tickets, each roller 1
Sufficient frictional force can be secured between Nos. 6 and 17 and the ticket, and it becomes possible to prevent the occurrence of separation errors and double feeding.

As described above, when the transportation speed of the ticket is switched according to the number of the tickets, the rotation speed of the feed roller 16 is also switched. That is, the peripheral speed of the feed roller 16 is V1 (mm / s) when conveying one ticket.
The peripheral speed of the feed roller 16 is switched to V2 (mm / s) when a plurality of tickets are conveyed and separated.

On the other hand, as described above, the separating roller 17 rotates in the forward direction when conveying one ticket, and reverses in separating a plurality of tickets. Separation roller 17 at this time
The peripheral speed is V3 (mm / s) in both forward and reverse rotation
Is set to. The peripheral speeds of the pickup rollers 18 and 19 on the downstream side of the separation roller 17 and the feed roller 16 are V4 (mm) higher than the peripheral speed of the feed roller 16.
/ S). That is, the magnitude relationship of the peripheral speeds of the rollers described above is V2 <V1 <V4.

FIG. 5 is a front view partially showing the upper and lower conveyor belts 23 and 24 and showing the front tension roller 9 and the front roller 10, and FIG. 6 is a side view thereof.

The upper conveyor belt 23 and the lower conveyor belt 24 are
As partially shown in FIG. 7, they are arranged in parallel with a gap T1 (mm). The gap T1 is the thickness T3 of the ticket.
It is larger than (mm). That is, the upper transport belt 23 and the lower transport belt 24 usually have the gap T1 (m
m) are separated from each other.

Therefore, the ticket entered with only one ticket is
While being placed on the lower conveyor belt 24, it is conveyed like a belt conveyor. In this state, the upper conveyor belt 23
Since the passenger ticket is not gripped between the lower conveyor belt 24 and the lower conveyor belt 24, there is almost no carrier force acting on the passenger ticket, and there is a high probability that the passenger will get a ticket jam.

Therefore, the front tension roller 9 and the rear tension roller 11 are directed toward the front roller 10 and the rear roller 12 only when one ticket that cannot be gripped is conveyed between the upper conveyance belt 23 and the lower conveyance belt 24. By pushing and pushing down, the upper transport belt 23 and the lower transport belt 24 grip the ticket to secure its transport force.

However, when a plurality of tickets are put in, the upper conveyor belt 23 and the lower conveyor belt 2 as described above.
When the ticket is gripped with 4, there is a high possibility that separation errors and double feeding will occur. In this case, therefore, the front tension roller 9 and the rear tension roller 11 are pushed up to release the grip of the ticket. .

Here, the mechanism for moving the front tension roller 9 and the rear tension roller 11 up and down will be described. Since the front tension roller 9 and the rear tension roller 11 are moved by substantially the same mechanism, the mechanism for moving the front tension roller 9 will be described here as a representative.

As shown in FIGS. 8 and 9, the moving mechanism for moving the front tension roller 9 includes a support shaft 50.
A bracket 52 rotatably attached to the support shaft 50 via a bearing 51; a roller bearing 54 attached to a rotation end of the bracket 52 via a roller shaft 53; and a bracket 52 pivoted downward. And a spring 55 that urges the The roller shaft 53 to which the front tension roller 9 is rotatably attached has a solenoid 1 for moving the front tension roller 9 upward against the biasing force of the spring 55.
3 is connected.

The front tension roller 9 includes a solenoid 13
In a normal state in which is not excited, the spring 55 pushes it down toward the front roller 10. This allows
The roller bearing 54 pushes down the upper conveyor belt 23 to bring it into contact with the lower conveyor belt 24. Lower conveyor belt 24
Are supported by the front rollers 10, so that when the upper transport belt 23 is pushed down,
It is gripped between the lower conveyor belt 24 and the lower conveyor belt 24 with a predetermined tension.

Further, for example, when it is detected through the thickness detection sensor 6 that a plurality of tickets have been inserted, the solenoid 13 is excited. As a result, the roller shaft 53 is pushed up against the biasing force of the spring 55,
The roller bearing 54 rises and the front tension roller 9
Is pushed up. When the front tension roller 9 is pushed up, the upper conveyor belt 23 is separated from the lower conveyor belt 24, a gap T1 (mm) is formed between the two, and the grip of the ticket is released.

Further, when it is detected by the thickness detecting sensor 6 that one inserted ticket has been inserted, the solenoid 13 is demagnetized. As a result, the roller shaft 53 is lowered by the urging force of the spring 55, the roller bearing 54 is lowered, and the front tension roller 9 is pushed down. When the front tension roller 9 is pushed down, the upper conveyor belt 23 is pressed against the lower conveyor belt 24, and the ticket is gripped between them.

FIG. 10 shows a pushing roller 1 for pushing a ticket between the separating roller 17 and the feed roller 16.
4 is shown, and a side view thereof is shown in FIG.

The urging mechanism of the pushing roller 14 includes a support shaft 60, a bracket 62 rotatably attached to the support shaft 60 via a bearing 61, and a shaft 63 at the rotating end of the bracket 62. And a spring 65 for urging the roller bearing 63 so as to press the roller bearing 63 against the lower drive roller 15. The ticket is gripped by the biasing mechanism between the pushing roller 14 and the lower driving roller 15 with tension F2 (g weight). The pushing roller 14 is formed of a metal roller, and the lower drive roller 15
Is formed of a rubber roller having a relatively high coefficient of friction.

For example, as shown in FIG. 12, when the two tickets P1 and P2 are conveyed in an overlapping state, the friction coefficient between the lower ticket P1 and the lower drive roller 15 is μ3. And the upper ticket P2 and the metal pushing roller 14
If the friction coefficient between and is μ4, the relationship of μ4 << μ3 is established. That is, since the pressing roller 14 is formed of a metal roller, μ4 has a very small value.

The force applied to the lower ticket P1 sent out in the forward direction by the feed roller 16 is F5 (g weight), and the reverse force applied to the upper ticket P2 separated by the separating roller 17 is F6 ( g), F5 = F1μ1−F
1μ2 + F2μ3-F2μ2 and F6 = F1μ1-
F1μ2-F2μ2-F2μ4. Here, since F2 is set to a much smaller load than F1,
The relationship of 5>F6> 0 is established.

On the other hand, compared with the force acting on the tickets P1 and P2 when the pushing roller 14 and the lower driving roller 15 are not provided (the state shown in FIG. 3), F5> F3 = F4
The relationship of>F6> 0 is established. Or F2
Considering that μ2 and F2μ4 are extremely small forces, it can be said that the relationship of F5> F3 = F4 = F6> 0 holds.

That is, by providing the pushing roller 14 and the lower drive roller 15, it is possible to increase only the carrying force of the lowest ticket in the overlapped state and to minimize the resistance to the remaining tickets. it can. Thereby, the separating performance of a plurality of tickets can be improved.

Even when a single ticket is conveyed, by providing the pushing roller 14 and the lower drive roller 15, the conveying force of the ticket can be increased by the load F2μ3 (g weight). , It has become possible to prevent ticket jams more effectively.

In FIG. 13, the separation roller 17 is opposed to the feed roller 16 with a constant gap T2 (mm), and the separation roller 17 is directed toward the feed roller 16 with a predetermined tension F1 (g weight). The structure for urging is shown in FIG. FIG. 14 shows a side view of the structure shown in FIG.

The support mechanism of the separation roller 17 includes a support shaft 70, a bracket 72 rotatably attached to the support shaft 70 via a bearing 71, and a roller bearing attached to the rotating end of the bracket 72. 78 and an arm 74 that supports the support shaft 70.
A spring S for urging the arm 74 downward with a constant urging force, and a spring S for contacting the lower end of the arm 74 with each other.
A stepping motor 76 that adjusts a gap T2 between the separation roller 17 and the feed roller 16 that is urged toward the feed roller 16 by. The stepping motor 76 functions as a gap forming mechanism.

The bracket 72 having the separation roller 17 attached to the tip thereof is rotatable around the support shaft 70, and the separation roller 17 can be retracted upward when a ticket is passed.

Further, the thickness detecting sensor 6 detects the thickness of the boarding ticket and detects the number of boarding tickets according to a plurality of slice levels set for the output.

The slice level is the output level of the thickness detection sensor 6 when the ticket is not inserted and the ticket 1
/ 2 sheets output level (slice level 1), 3/2 outputs level (slice level 2), 5/2 sheets output level (slice level 3), 7/2 sheets output level (slice level 4) Is set for each.

If the slice level is 1 or less, 0
1 sheet if slice level 1 or more and 2 or less, 2 sheets if slice level 2 or more and 3 or less, slice level 3
If the number is 4 or less, the number is 3, and if the slice level is 4 or more, the number is 4, or more.

That is, the thickness detection sensor 6 allows the above-mentioned five kinds of states (0, 1, 2, 3, 4 or more).
Can be determined. The operation of the separating mechanism 100 is controlled in the following manner according to the number of tickets that are detected by the thickness detecting sensor 6.

In this embodiment, the thickness detecting sensor 6
The slice level was set at 4 levels, which means that the number of tickets that can be inserted during normal processing of the automatic ticket gate is 3
It is set from the product specification of less than one sheet,
It can be changed arbitrarily.

FIG. 15 is a block diagram showing the drive control system of the separating mechanism 100 described above.

The drive control system of the separation mechanism 100 has a control means 82 which functions as the control unit of the present invention. The thickness detecting sensor 6 and a plurality of ticket detecting sensors 30 to 43 are connected to the control means 82. Further, the control means 82 includes the first to third drive motors 20, 21,
22, solenoid 13, and stepping motor 76
Are connected.

The control means 82 detects the number of tickets and the transportation position based on the detection signals from the thickness detection sensor 6 and the sensors 30 to 43, and the first to third drive motors 20 and 21 ,. 22 and the solenoid 13 are driven and controlled.

Next, the separating mechanism 1 configured as described above.
The operation of separating and transporting a ticket by 00 will be described with reference to the flowcharts shown in FIGS. 16 to 20.

As shown in FIG. 16, first, the main loop is started (step 1), and it is judged whether or not the sensor 30 or the sensor 31 is obstructed by the ticket and becomes dark (step 2). When it is determined that the sensor 30 or the sensor 31 is dark (step 2; YES), a timer for counting the time T1 (s) is set (step 3), and the retry count W is reset (step 4). ).

Then, triggered by such a ticket insertion, the second drive motor 21 is driven at a speed V1 (m / s).
The conveyor belts 23 and 24, the lower drive roller 1
5 and the feed roller 16 are rotated in the forward direction (step 5). At the same time, the third motor 22
The lower pickup roller 19 is normally rotated at a speed V4 (m / s) higher than 1 (m / s), and the lower pickup roller 19 is rotated in the forward direction (step 6). At this time, the solenoid 13 is not excited, and the front tension roller 9 and the rear tension roller 11 are the front roller 10 and the rear roller 1, respectively.
It is pressed to 2.

When the ticket is conveyed in this state, the thickness detection sensor 6 determines whether or not there is one or more tickets (step 7). If it is determined that the number is one or more (step 7; YES), the output of the thickness detection sensor 6 is compared with a plurality of preset slice levels to determine the number of tickets (step 8).

When it is judged in step 8 that the number of the passenger tickets inserted is one (step 9; NO), the sensor 3
On the condition that any of 6 to 41 becomes dark (step 10; YES), the first drive motor 20 is driven at the speed V3.
The separation roller 17 is rotated in the forward direction at (m / s), and is rotated in the forward direction (step 11).

Then, the time T set in step 3
On condition that at least one of the sensor 42 and the sensor 43 becomes dark within 1 (s) (step 12; Y
ES), a timer for counting the time T2 (s) is set (step 14). Furthermore, time T2
Under the condition that both the sensors 40 and 41 become clear in (s) (step 15; YES), the first drive motor 2
0 and the second drive motor 21 are stopped (steps 17 and 18).

In this way, one ticket is used for the sensor 40,
When passing 41, the first and second motors 20, 21
By stopping the operation, even if a plurality of tickets are inserted one by one without being stacked, it is possible to prevent the second and subsequent tickets from being continuously sent out.

As described above, when the thickness detecting sensor 6 detects that the ticket is a single ticket, the separation roller 17 is rotated in the normal direction to cause a jam of a bent ticket. It is possible to reliably send out from the separating mechanism 100 without.

On the other hand, when it is judged in step 8 that the inserted tickets are two or three stacked tickets (step 9; YES, step 19; N).
O) under the condition that at least one of the sensor 36 and the sensor 37 is dark (step 20; YE
S), the solenoids 13 and 13 are turned on (step 2)
1). As a result, the gripping force of the transport belts 23 and 24 is released, and the overlapping tickets become separable.

At the same time, the first drive motor 20 drives the speed V3.
(M / s), the separation roller 17 is rotated in the reverse direction (step 22), and the second drive motor 21 is rotated at the speed V1.
The speed is reduced from (m / s) to V2 (m / s) (step 23). As a result, the transportation speed of the ticket is V2 (m / m
The speed is reduced to s) to improve the separation performance, and a plurality of tickets are separated and sent out one by one.

Then, the time T set in step 3
On condition that the separated first ticket reaches the pickup rollers 18 and 19 and at least one of the sensors 42 and 43 becomes dark within 1 (s) (step 24; YES). The second drive motor 21 is stopped and the transportation of the ticket is interrupted (step 26), and the timer for counting the time T3 (s) is set (step 27).

Further, on condition that both the sensors 42 and 43 have become clear within the time T3 (s) set in step 27 (step 28; YES), the first ticket is separated by the separating mechanism 100. The first drive motor 20 is stopped, the separation roller 17 is stopped (step 30), and the excitation of the solenoid 13 is released (step 31).

As described above, when the separated first ticket arrives at the pickup rollers 18 and 19, the second drive motor 21 is stopped to interrupt the transportation of the second ticket. It is possible to prevent the second ticket from being conveyed in a state where it overlaps with the first ticket.

After the first drive motor 20 is stopped in step 18 and the solenoid is de-energized in step 31, it is determined whether or not there is a subsequent ticket to be conveyed (step 32). . If it is determined in step 32 that there is no subsequent ticket (step 32; N
O), the main loop is terminated and the operation of the separation mechanism 100 is terminated (step 33).

On the other hand, when it is determined in step 32 that there is a subsequent ticket (step 32; YES), the second drive motor 21 is rotated forward at the speed V2 (m / s) to convey the ticket. Is restarted (step 34), and it is determined whether the number of subsequent tickets is one (step 3).
5).

Then, in step 35, the succeeding ticket is 1
If it is determined that the number of tickets is one, the process proceeds to step 10 and the remaining one ticket is processed. At this time, the separation roller 17 is normally rotated, the ticket is conveyed at a speed V1 (m / s), and the excitation of the solenoid 13 is released. In other words, in this case, the processing is the same as when one ticket is inserted.

On the other hand, if it is determined in step 35 that there are two subsequent tickets, the process proceeds to step 20 and two tickets are processed. At this time, the separation roller 17 is reversed and the ticket is conveyed and processed at the speed V2 (m / s). The solenoid 13 remains excited.

On the other hand, when it is determined in step 8 that the inserted tickets are four or more overlapping tickets (step 19; YES), the process by the automatic ticket gate is impossible. It is determined that there is, the first drive motor 20 and the second drive motor 21 are stopped (step 36), and it is determined whether or not it can be returned by communication with the host (step 37).

If it can be returned (step 37; YE)
S), the first and second drive motors 20 and 21 have a speed V5.
It is reversely rotated at (m / s) (step 38), and all the tickets are returned through the slot 1. Then, it is determined whether or not the return of the ticket has been completed (step 39),
If all the tickets have been removed and returned (step 39; YES), the upper ticket is notified and the next ticket reception wait state is entered, and the first and second drive motors 2
The rotations of 0 and 21 are stopped (step 40).

FIG. 21 is a flow chart for explaining the details of the operation for determining the number of sheets in step 8.

When the number of sheets is judged through the thickness detection sensor 6, first, at least one of the sensors 32 and 33 becomes dark (step 101;
If YES, the slice level S is reset (step 102). Then, the output level S of the thickness detection sensor 6
1 is compared with a preset slice level S (steps 103 and 104), and the number of tickets is determined (step 105). Further, on condition that both the sensor 30 and the sensor 31 become clear (step 106; YE
S), the number of sheets determination processing operation is ended.

That is, the above-described thickness detection sensor 6 has a constant cycle until the separating operation of all the inserted tickets is completed or all the tickets are returned through the slot 1. Monitor the ticket thickness. And
Whenever there is a change in the thickness of the ticket, the separation mechanism 100 executes a predetermined processing operation according to the thickness.

For example, for two tickets that are inserted in a squeezed state, the judgment value may change to two even if the thickness detection sensor 6 first judges that the ticket is one. . Particularly, when the determination result by the thickness detection sensor 6 changes from one sheet to two sheets after the sensor 36 or the sensor 37 becomes dark, the first drive motor 20 has already been normally rotated and the separation roller 17 is normally rotated. From the rotated state, the first drive motor 20 is instantaneously stopped and rotated in the reverse direction, and the separation roller 17 is rotated in the reverse direction. At the same time, the second drive motor 21, which is rotating forward at the speed V1 (m / s), moves at the speed V2 (m / s).
And the solenoid 13 is excited.

That is, as for the output level of the thickness detection sensor 6, the maximum value is constantly updated and stored, the number of boarding tickets is determined according to this maximum value, and a predetermined process according to the number of boarding tickets is performed. It is supposed to be done.

Next, with reference to the flowcharts shown in FIG. 22 to FIG. 25, together with the flowcharts shown in FIG. 16 to FIG.

In the above-described automatic ticket gate apparatus for a plurality of sheets, generally, the jam of the ticket in the separating mechanism 100 is a major factor that impairs the reliability of the apparatus. In order to reduce the jam in the separating mechanism 100, the separating mechanism 100 according to the present embodiment is configured to perform the separation retry processing of the ticket. The separation retry process is a process of separating the ticket that has not been normally separated through the separation mechanism 100 again.

The jam of the ticket is determined as follows, for example. The ticket entered through the slot 1 has a speed V1 when triggered by passing through the sensors 30 and 31.
When the conveyance is started at (m / s) and the conveyance is normally performed, at least one of the sensor 42 and the sensor 43 is reached within the time T1 (s). That is, even if the time T1 (s) elapses after the sensors 30 and 31 become dark, the sensor 42
Alternatively, when the sensor 43 does not go dark, the jam of the ticket is determined. In addition, even if at least one of the sensor 42 and the sensor 43 becomes dark and the sensor 40 and the sensor 41 do not become visible even after the time T2 (s) has passed, the jam of the ticket is determined.

That is, if the time-out is determined in step 13 of FIG. 17 (step 13; YES) or if the time-over is determined in step 16 (step 16; YES), the jam of the ticket is determined. In addition, when the time-over is determined in step 25 of FIG. 18 (step 25; YES), or when the time-over is determined in step 29 (step 29; YE).
S), the jam of the ticket is judged.

When a jam is generated in a single ticket (step 13; YES, step 16; YE)
S), first, the retry count W reset in step 4 of FIG. 16 is incremented by 1 (FIG. 22; step 41).
Then, on condition that the number of retries W has not reached the preset number W1 (step 42; NO), the separation retry process is performed, and the first drive motor 20 which is normally rotated is stopped ( At the same time as step 43), the second drive motor 21 that is rotating forward is stopped (step 44). The number of separation retries W1 can be arbitrarily set.

At the same time, the timer for counting the time T4 (s) is set (step 45), and the first drive motor 20 and the second drive motor 21 are set to the speed V5 (m).
/ S) is reversed (steps 46 and 47). And
After time T4 (s) has elapsed (step 48; YE
S), the first drive motor 20 and the second drive motor 2
1 is stopped together (steps 49 and 50). In this state, one jammed ticket is returned to the vicinity of the slot 1.

Further, the second drive motor 21 is driven at the speed V1.
While being rotated forward at (m / s) (step 51),
The first drive motor 20 is normally rotated at the speed V3 (m / s) (step 52), and the transportation of the ticket is restarted. At the same time, a timer for counting the time T1 (s) is set (step 53). After that, the process proceeds to step 12 of FIG. 17, and it is monitored whether the ticket is normally passed through the separation mechanism 100.

By the way, at step 42, the number of retries W
Is determined to exceed the preset number of times W1 (step 42; YES), it is determined that the separation retry process cannot eliminate the jam (FIG. 23; step 5).
4) All the drive motors 20, 21, 22 are stopped (steps 55, 55, 57) and the solenoid 1
3 is excited (step 58).

After that, the predetermined jam processing is performed by the operator and the boarding ticket having the jam is removed (step 59; YES), and the separation retry operation is ended.

On the other hand, when a jam occurs in a ticket in which two or three sheets are stacked (FIG. 18, step 25; Y).
ES, step 29; YES), first, the retry count W reset in step 4 of FIG. 16 is incremented by 1 (FIG. 24; step 60). Then, on condition that the number of retries W has not reached the preset number W1 (step 61; NO), the separation retry process is performed,
The reversely rotating first drive motor 20 is stopped (step 62), and the forward rotating second drive motor 21 is stopped (step 63). at the same time,
The solenoid 13 is demagnetized (step 64).

At this point, the stop positions of a plurality of jammed tickets (hereinafter, simply referred to as jammed tickets) are determined through the plurality of sensors 30 to 43 (steps 65 and 6).
6, 67), the separation retry processing of a plurality of patterns according to the jam occurrence position is executed.

First, when the leading edge of the jam ticket exceeds the pickup rollers 18 and 19 and at least one of the sensors 42 and 43 is dark (step 6).
5; YES), or when the jam ticket has not reached the separation roller 17 and the sensors 38 to 43 are all bright (step 65; NO, step 66; NO,
(Step 67; NO) As in the case of jamming one ticket, the timer for counting the time T4 (s) is set (step 68), and the first drive motor 20 and the second drive motor are set. 21 is reversed at speed V5 (m / s) (steps 69 and 70). And time T4
After (s) has passed (step 71; YES), both the first drive motor 20 and the second drive motor 21 are stopped (steps 72, 73), and the jam ticket is returned to the vicinity of the slot 1.

After that, the timer for counting the time T1 (s) is set (step 74), and the process is returned to step 21 in FIG. And solenoid 1
3 is excited and the first drive motor 20 drives the speed V3 (m / m
s), the second drive motor 21 rotates at the speed V2 (m
/ S) for normal rotation, and the separation retry process for the jam ticket is executed.

Secondly, the leading edge of the jam ticket is the separating roller 17
And at least one of the sensors 40 and 41 is dark beyond the feed roller 16, and the sensor 4
When both 2 and 43 are clear (step 65;
NO, step 66; YES), that is, when the leading edge of the jam ticket is between the separation roller 17 and the pickup roller 18, as shown in FIG.
Is excited and the restraint force by the conveyor belts 23 and 24 is released (step 75). And the jam ticket is the distance H
(Mm) so that the first drive motor 20 and the second drive motor 21 return at a speed V6 (m /
In s), it is reversely rotated and stopped (steps 76, 7).
7). In this state, the leading edge of the jam ticket is returned to near the separation roller 17 and the feed roller 16.

After that, the first driving motor 20 is rotated in the forward direction and the separating roller 17 is rotated to the extent that the uppermost ticket which is in rolling contact with the separating roller 17 is conveyed in the forward direction by the distance I (mm). Forward rotation is performed at speed V7 (m / s) (step 7
8) At the same time, to the extent that the second drive motor 21 is rotated in the forward direction and the lowest ticket that is in rolling contact with the feed roller 16 is conveyed in the forward direction by a distance J (mm) shorter than the distance I described above. The feed roller 16 is normally rotated at a peripheral speed V8 (m / s) (step 79). As a result, the uppermost ticket is conveyed in the forward direction by a distance (IJ) more than the lowermost ticket, and the uppermost ticket is sent out prior to the lowermost ticket. This state is shown in FIG.

The above-mentioned magnitude relation of the distance is K (m) from the nip between the separation roller 17 and the feed roller 16 to the nip between the pickup rollers 18 and 19.
m), the relationship of K>I>J> H is satisfied. In addition, the magnitude relation of the speeds described above is V4>V1> V
It is assumed that the relationships of 2> V6 and V4>V1>V2>V7> V8 are satisfied.

Then, in this state, the outputs of the sensors 42 and 43 are monitored (steps 80 and 81), and after at least one of the sensors 42 and 43 becomes dark, both sensors 42 and 43 become bright. On the condition (step 80; YES, step 81; YES), it is determined that the uppermost ticket has been sent out from the separating mechanism 100 by the pickup rollers 18 and 19, and the process proceeds to step 31 in FIG. To be done.

On the other hand, even if the jam ticket is shifted as described above, both the sensor 42 and the sensor 43 remain bright (step 80; NO), or at least one of the sensor 42 and the sensor 43 becomes dark. When it is not clear by either one of the sensors 42, 43 (step 80; YES, step 81; NO), this time, the first drive motor 20 speeds so as to convey the uppermost ticket by the distance I. At the same time as the normal rotation of V7 (m / s) (step 82), the second drive motor 21 moves at the speed V8 (m) so as to convey the bottommost ticket in the opposite direction by the distance J.
/ S) is rotated in the reverse direction (step 83).

In this state, the outputs of the sensors 42 and 43 are monitored again (steps 84 and 85), and at least one of the sensors 42 and 43 becomes dark and then both sensors 42 and 43 become bright. Under the condition (step 84; YES, step 85; YES), the uppermost ticket is separated by the pickup rollers 18 and 19 from the separation mechanism 1.
It is determined that the data has been sent from 00, and the process proceeds to step 31 in FIG.

However, both sensor 42 and sensor 43 still remain clear (step 84; N).
O) or when at least one of the sensors 42 and 43 is dark but neither one of the sensors 42 and 43 is bright (step 84; YES, step 85; NO), step 60 in FIG. Processing is transferred.

Thirdly, the leading edge of the jam ticket is the separating roller 17
And the sensors 40 to 43 are located in front of the nip between the feed roller 16 and all of them (step 6
5; NO, step 66; NO), and sensors 38, 3
If at least one of 9 is dark (Step 6
5; NO, step 66; YES), that is, when the leading edge of the jam ticket is immediately before the nip between the separation roller 17 and the feed roller 16, the solenoid 13 is excited (step 86). Then, steps 76 and 7 of FIG.
Step 7 except the processing of 7 (processing of returning the jam ticket)
The process shifts to the process of No. 8.

That is, when the leading edge of the jam ticket exceeds the nip between the separation roller 17 and the feed roller 16 as in the second pattern, it is necessary to return the jam ticket once in the opposite direction. When the leading edge of the jam ticket is in front of the nip between the separation roller 17 and the feed roller 16 as in the case of the pattern No. 3, it is not necessary to return the jam ticket. In other words, in the second pattern, if the jam tickets are sent out in the forward direction as they are, the jam tickets may be pulled out by the pickup rollers 18 and 19 and overlapped, but in the third pattern. Even if the jam ticket is conveyed in the forward direction as it is, there is no risk of double feeding.

After the retry processing of the above-mentioned first to third patterns is executed, when a plurality of boarding tickets are jammed again, the conveyance positions of the jam tickets are plural sensors 30 to 43.
It is determined through the step S1, and the separation retry process according to the jam occurrence position is executed again.

However, when it is determined in step 61 that the number of retries W exceeds the preset number W1 (step 61; YES), it is determined that the jam cannot be eliminated by the separation retry process (FIG. 23; step 5).
4) All the drive motors 20, 21, 22 are stopped (steps 55, 55, 57) and the solenoid 1
3 is excited (step 58).

After that, the predetermined jam processing is performed by the operator and the boarding ticket in which the jam has occurred is removed (step 59; YES), and the separation retry operation is ended.

As described above, in the present embodiment, when the ticket jam occurs before and after the nip between the separation roller 17 and the feed roller 16 as described in the above-mentioned pattern 2 and pattern 3, the separation roller is used. The 17-side ticket (upper ticket) is sent before the feed roller 16-side ticket (lower ticket). As a result, at the time of the separation retry process, the method of separating the tickets can be changed to the opposite of the conventional one, and the separation performance can be improved. Further, according to the present embodiment, since the separation retry processing of the different plural patterns described above is executed according to the position of the jam ticket, it is possible to perform the appropriate processing according to the state of the jam ticket and further improve the separation performance. I was able to improve.

Here, referring to FIGS. 26 and 27,
The behavior of the jam ticket and the behavior of the separation roller 17 during the above-described separation retry processing of the patterns 2 and 3 will be described. In this case, 2
The behaviors of the jam ticket and the separation roller 17 will be described by taking as an example the case where a jam occurs on each of the boarding tickets P1 and P2.

In the separation retry processing of the above-mentioned patterns 2 and 3, as shown in FIG. 26, the ticket P2 on the separation roller 17 side is sent out prior to the ticket on the feed roller 16 side. That is, the upper ticket P2 is first sent to the nip between the pickup rollers 18 and 19.

At this time, the pickup rollers 18 and 19
Force F1 in the pull-out direction on the ticket P2 leading from
0 means that when the tension with which the upper pickup roller 18 is pressed against the lower pickup roller 19 is F7 (g-weight), F10 = F7μ1- (F), assuming that the separation roller 17 and the feed roller 16 are stopped.
1 μ1 + F1 μ2). That is, the ticket P2 is F
When 10> 0 is satisfied, it is pulled out by the pickup rollers 1 and 19.

On the other hand, the separation roller 17 and the feed roller 1
Lower ticket P that is pinched and restrained by 6 and remains in place
1, the force of F1μ2 is applied from the upper ticket P2 that is pulled out by the pickup rollers 18 and 19, but the feed roller 16 is stopped and the ticket P1 is applied.
Is larger than F1μ1 (F1μ1-F1μ2>
Therefore, the ticket P1 on the lower side stays on the spot.

By the way, in the state in which the two tickets P1 and P2 are interposed between the separation roller 17 and the feed roller 16, as shown in FIG.
The separation roller 17 retracts slightly upward. In this case, as shown in detail in FIGS. 13 and 14, the separation roller 1
The bracket 7 moves upward as the bracket 72 swings around the support shaft 70. That is, another force for retracting the separation roller 17 acts on the upper ticket P2 that is pulled out by the pickup rollers 18 and 19. In other words, the ticket P2 is additionally applied with the resistance force F8 in the direction opposite to the pulling-out direction.

Therefore, if the resistance F8 is large, the upper ticket P2 may not be pulled out. Specifically, the pull-out direction force F10 ′ = F7μ1− (F1μ1 + F1) applied to the ticket P2 in consideration of the resistance force F8.
.mu.2 + F8), and if F8 is so large that F10 'becomes F10'<0, the ticket P2 cannot be pulled out.

On the other hand, the rotational moment M acting on the separation roller 17 when the ticket P2 is pulled out is determined by the bracket 72.
Is L and the angle formed by the moving direction of the separating roller 17 with respect to the pulling-out direction of the ticket P2 is θ, M = F
1 μl Lcos θ. In other words, this moment M reduces the resistance force F8 and allows the passenger ticket P2 to be pulled out. That is, when the resistance force after being reduced by the moment M is F9, F7μ1- (F1μ1 +
By satisfying F1μ2 + F9)> 0, the ticket P2 can be pulled out.

As described above, according to the present embodiment, when the pick-up rollers 18 and 19 pull out the ticket, the separating roller 17 can be retracted upward, so that the separating roller 17 gives it to the ticket. The resistance can be reduced. As a result, the ticket can be pulled out easily and reliably, and unnecessary stress is not applied to the ticket. Therefore, it is possible to prevent a trouble that the passenger ticket is damaged due to friction or the like when the passenger ticket is pulled out and the passenger feels heat.

The present invention is not limited to the above-described embodiments, but can be variously modified within the scope of the present invention.
