Abstract

PURPOSE:To prevent the clogging of tickets by providing additionally a shutter provided to the carrying path of tickets and a roller retaining plate interlocking therewith. CONSTITUTION:A retaining plate 2 provided additionally to the shutter 1 releases the pressure from a driving roller 3 at the closing of the shutter by releasing the pressure by the driving roller 3 exerted on the carrying part 5 and the carrying force exerted to a ticket 4 in standby becomes very weak. When the processing of the preceding ticket is finished, the shutter 1 opens the carrying path, the retaining plate 2 presses the drive roller 3 in interlocking therewith and the strong carrying force is exerted to the ticket 4 in standby. Thus, the mechanism varying the drive roller pressure by the retaining plate 2 is adopted to attain the control of the carrying force being a cause to the fault simply by the mechanical mechanism.

Description

[Detailed Description of the Invention] [Summary] This is a mechanism that changes the drive roller pressure in order to change the general feeding force of the ticket inserted into the refund operation vehicle, and the mechanism that changes the general feeding force of the ticket inserted into the refund operation vehicle, and which continuously feeds subsequent tickets while processing the inserted ticket. Even if the material is injected, the shutter prevents it from entering the processing section and weakens the conveying force.
Conventionally, a steady strong conveyance force was applied to the blocked ticket, which caused jamming (ticket jamming).

[Industrial application field]

The present invention relates to a refund operation console that automatically performs the calculation process for refunding winning betting tickets as part of the automation of selling winning betting tickets for public horse racing.

To be more specific, when operating the refund operation console, if you insert the next ticket while processing one ticket, mechanically the ticket inserted during processing will enter the processing section. However, this method has been a source of jamming problems.

Therefore, jamming problems can be avoided by inserting the next ticket after the processing is completed, but since the refund counter for pari-mutuel betting tickets is flooded with refund customers after the race ends, it is necessary to make the refund calculation process more efficient. There is a strong demand for a refund operation console that does not cause problems even when a pari-mutuel betting ticket is inserted.

[Conventional technology]

A mechanical diagram of a conventional refund operation console is shown in FIG. 3 (al).

If the next ticket is subsequently inserted while one ticket is being processed, the shutter 31 prevents it from entering the calculation processing section, and the system waits until the processing of the previous ticket is completed. .

A constant conveying force is constantly applied to the waiting ticket 34 from the drive roller 33, and this may cause the waiting ticket to deform due to the pressure of the conveying force, causing a jam. .

However, this type of failure is dealt with as a follow-up maintenance process, and each time a failure occurs, the jammed ticket is manually removed and recovery measures are taken, and no particular consideration is given to mechanical jam prevention measures. It wasn't.

[Problem that the invention seeks to solve]

As described above, the conventional mechanism of the refund operation console, which requires manual handling when a jam occurs, has the following problems.

(1) When one ticket is inserted for refund processing, the shutter 31 closes the conveyance path as shown in FIG. and waits until processing of the preceding ticket is completed.

However, a conveying force is constantly applied to the waiting ticket 34 by the drive roller 33, and this causes the ticket 34 to push up the shutter 31 and enter the interior.
Otherwise, a problem such as the tip being pushed and bent may occur.

FIG. 3 (bl, (C)) illustrates the state in which defects occur due to such a conventional mechanism.

FIG. 3(b) shows that the shutter 31 that closes the conveyance path is
It is a diagram showing a state where the ticket 34 is pushed up by a waiting ticket 34 whose entry is blocked.

The figure (C1) shows a state in which the ticket 34, which is blocked from entering by the shutter 31 and is waiting, has its leading end bent by a strong conveying force that is constantly applied even during the waiting period.

When the situation shown in FIG. 6B occurs, the next ticket enters the processing section while the preceding ticket is being processed, interfering with the processing.

Furthermore, if the state shown in FIG. 2C occurs, a jam occurs in the conveyance path, and in either case, the function of the refund operation console is interrupted.

[Means for solving problems]

FIG. 1 shows a principle diagram of the variable drive roller pressure mechanism of the present invention.

When a ticket requiring processing is inserted into the refund operation console, a shutter 1 interlocked with a solenoid 5 closes the conveyance path and prevents the subsequently inserted ticket 4 from entering the processing section.

At this time, a holding plate 2 attached to the rear of the shutter 1
As a result, the drive roller 3 that had been pressurized until then is released.

When the drive roller 3 is released from the pressure of the pressing plate 2, the conveyance force applied to the conveyance path 5 weakens.

In this way, even if the next ticket is inserted while one ticket is being processed, a strong conveying force will not be applied to the waiting ticket 4 as in the conventional system, as explained above.

By providing the above-described mechanism, the above-mentioned problem of the refund operation console being interrupted can be solved.

[Effect]

While one ticket is being inserted into the refund operation console and being processed, the shutter 1 closes the conveyance path and blocks the entry of the subsequently inserted ticket 4 until the processing capacity of the preceding ticket is exceeded. In the standby mechanism, a pressing plate 2 attached to the shutter 1 releases the pressure on the drive roller 3 when the shutter is closed. As a result, the pressure applied by the drive roller 3 to the conveyance path 5 is also removed, and the conveyance force applied to the waiting ticket 4 becomes extremely weak.

When the processing of the preceding ticket is completed, the shutter 1 opens the conveyance path, and in conjunction with this, the pressing plate 2 presses the drive roller 3, applying a strong conveyance force to the ticket 4 that has been kept on standby.

In this way, the mechanism for varying the drive roller pressure by the pressing plate 2 has made it possible to easily control the conveying force, which was a factor in countermeasures against failures, using a mechanical mechanism.

〔Example〕

FIG. 2 is a diagram showing an embodiment of the present invention.

When a ticket that requires refund processing is inserted into the refund operation console, the shutter 1 driven by the solenoid 6 closes the conveyance path, and the shutter 1 closes the conveyance path to prevent the subsequently inserted ticket 4 from entering the interior. An example of a mechanism is shown in which a presser plate 2 interlocked with the drive roller 3 acts on the drive roller 3 to vary the conveying force applied to the ticket 4.

(1) FIG. 2 (al) is a type in which pressure by a presser 2 is indirectly applied to the rotating portion of the drive roller 3 via a friction plate 7.

(2) FIG. 2 (bl) is a type in which the pressing plate 2 that interlocks with the shack 1 is Y-shaped and acts directly on the rotation axis of the drive roller 3.

〔Effect of the invention〕

As described above, the present invention makes it possible to solve the problem of function interruption, which was a problem with conventional refund operation consoles, by adding simple parts, and it can be integrated with the automatic pari-mutuel betting ticket vending machine. This is extremely useful from a practical point of view, as it can improve the efficiency of refund counter operations.
