Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a dressing sheet, a dressing method using the dressing sheet,
The present invention also relates to a sheet medium processing apparatus, and particularly to a dressing method for a roller that conveys a sheet-shaped medium, a dressing sheet applied to the method, and a sheet medium processing apparatus.

[0002]

2. Description of the Related Art Automatic ticket gates that handle various types of tickets such as ordinary tickets, commuter tickets, prepaid cards, etc. as sheet media include an insertion slot, an alignment section, a reading section, a writing section, a printing section, and a punch section. , Outlet, etc. In such an automatic ticket gate, tickets are transported at a high transport speed of approximately 2 m / s through most of the processing units. A rubber roller is often used in a transport mechanism for transporting tickets. The rubber roller produces a driving force (conveying force) due to the contact with the sheet medium due to the high friction coefficient.

However, when the surface of the rubber roller is contaminated with ink or oil, the coefficient of friction is greatly reduced. For this reason, the original conveying force of the rubber roller cannot be transmitted to the sheet-shaped medium.

In particular, an automatic ticket gate, which has recently been put into practical use and is capable of receiving a plurality of tickets, has a slot and an aligning section so that even when a plurality of tickets are stacked, they can be processed. In between, there is provided a separation unit that separates a plurality of tickets one by one and sends them out to the downstream side in the transport direction.

In this separating unit, a plurality of sheets are formed by a conveyance driving body for driving the conveyance toward the downstream side in the conveyance direction and a reverse feeding drive body for driving the conveyance backward facing the upstream side in the conveyance direction. The sheet-shaped medium is separated. These driving bodies are constituted by rubber rollers or conveyor belts. Since the driving force is transmitted to the sheet-shaped medium by friction with these driving bodies, in order to separate a plurality of sheet-shaped mediums, the sliding resistance, that is, the frictional force between the overlapping sheet-shaped mediums is more than the driving force. The condition is that the frictional force between the body and the sheet medium is high.

However, in an automatic ticket gate that processes a huge amount of sheet-shaped medium, that is, tickets, every day, the outer peripheral surface of the rubber roller is contaminated by the contact with the sheet-shaped medium, and a high friction coefficient is always maintained. I can't. Therefore, there is a possibility that problems such as being unable to convey the sheet-shaped medium at the originally required speed and feeding multiple sheets without being able to separate the sheet-shaped medium may occur.

When oil adheres to the rubber roller, it swells and the shape of the roller changes. When the sheet-shaped medium passes through the rubber roller whose outer periphery is deformed, skew (rotation) or deviation may occur. In the separation section, it is necessary to form an appropriate gap between a pair of rubber rollers that form the conveyance driving member and the reverse feeding driving member in order to separate a plurality of sheet-shaped media. Changes, which makes it difficult to separate a plurality of sheet-shaped media.

These problems are caused by the fact that the outer peripheral surface of the rubber roller is contaminated by the ink printed on the sheet-shaped medium. Especially in automatic ticket gates, the amount of processing is enormous, so it is necessary to clean it daily, but it is difficult to remove the rubber roller daily to clean the dirt adhering to the outer peripheral surface, and it has not been practically implemented. is the current situation.

Sheet-shaped media coated with such inks are used not only in tickets, but also in banknotes, various labels, and entrance tickets to facilities, and process these sheet-shaped media. The same problem occurs in the apparatus and the manufacturing apparatus.

[0010]

As described above, in the sheet medium processing apparatus such as the automatic ticket gate, the ink or hand grease applied to the sheet medium adheres to the outer peripheral surface of the rubber roller, and the friction coefficient is lowered. As a result, there is a risk of impairing the transporting ability and the separating ability. In addition, when the rubber roller swells due to the adhered dirt and the outer periphery is deformed,
There is a possibility that skew may occur, transport capability may be reduced, and separation capability may be reduced. Further, in a sheet-shaped medium processing device having a huge amount of processing such as an automatic ticket gate, the rubber roller becomes dirty in a short time, but frequently removing and cleaning the rubber roller increases the burden on the staff. There is a risk.

Therefore, the present invention has been made in view of the above-mentioned problems, and an object thereof is to make it possible to remove dirt adhering to the roller surface in a short time and maintain a high friction coefficient of the roller. Another object of the present invention is to provide a dressing sheet capable of preventing the roller from being deformed due to swelling, and a dressing method using the same.

[0012]

A dressing sheet according to a first aspect of the present invention comprises a sheet-like substrate and a dressing portion having irregularities formed on at least one surface of the substrate, It is characterized in that the dressing portion is brought into pressure contact with a carrying roller for carrying a medium to polish the surface of the carrying roller.

In the dressing method according to the second aspect of the present invention, a dressing sheet having a dressing portion having irregularities formed on at least one surface of a sheet-like substrate is fixed, and the dressing portion of the dressing sheet is fixed. It is characterized in that it is sandwiched between a pair of transport rollers that are driven by rotating independently of each other, and the surface of the transport rollers is polished by rotating the pair of transport rollers.

According to a third aspect of the present invention, there is provided a sheet medium processing apparatus which includes a receiving means capable of receiving a plurality of sheet mediums, and a separation roller which separates the plurality of sheet mediums received by the receiving means. Means, a processing means for performing a predetermined process on the sheet medium separated by the separating means, and the dressing portion of the dressing sheet based on receiving a dressing sheet having a dressing portion by the receiving means. And a control means having a dressing mode for polishing the separation roller by driving the separation roller while fixing the dressing sheet in a state of being pressed against the separation roller.

According to this dressing sheet and the dressing method using the same, the surface of the carrying roller can be dressed by rotating the carrying roller while the dressing portion of the dressing sheet is pressed against the surface of the carrying roller. it can. This makes it possible to remove the dirt attached to the surface of the transport roller in a short time.

Therefore, the transport roller can maintain a high friction coefficient. Further, it is possible to prevent the deformation of the transport roller due to the adhesion of dirt. For this reason,
It is possible to prevent a decrease in the carrying capacity of the carrying roller and a decrease in the separating capacity. In addition, since it is not necessary to frequently remove the transport roller for cleaning, it is possible to reduce the burden on the staff.

BEST MODE FOR CARRYING OUT THE INVENTION A dressing sheet and a dressing method using the same according to an embodiment of the present invention will be described below with reference to the drawings. (First Embodiment) As shown in FIGS. 1A and 1B, a dressing sheet 10 according to the first embodiment includes a sheet-shaped substrate 12 and at least one of the substrates 12. And a dressing portion 14 formed on the surface. Also, this dressing sheet 10
Is provided with a cleaning unit 16 formed on at least one surface of the substrate 12 as necessary.

In this embodiment, the dressing portion 14 and the cleaning portion 16 are both formed on both sides of the substrate 12. In addition, in the example shown in FIG. 1, the dressing portion 14 and the cleaning portion 16 are both formed at only one location, but it goes without saying that they can be variously changed according to the positional relationship of the rollers to be dressed.

The substrate 12 has a predetermined thickness. It is desirable that the thickness of the substrate 12 be close to the gap formed between the pair of rollers to be dressed. The thickness of the substrate 12 is several times the gap between the rollers, that is, about 5 times the thickness (gap) of the sheet medium when the roller shaft is elastically fixed.

The substrate 12 is made of a metal such as stainless steel, a resin (plastic) such as PET (polyethylene terephthalate), a ceramic such as carbon fiber paper, etc., as long as it is durable against bending. .

The dressing portion 14 has irregularities and is pressed against a driver to be dressed, for example, a roller to polish the surface of the roller. This dressing portion 14 is provided on the substrate 1

The second predetermined area, that is, the area corresponding to the position of the dressing target roller when the dressing sheet 10 is fixed is formed. For example, the dressing unit 14
Are formed in a strip shape substantially parallel to the rotation axis of the dressing target roller. As a result, it is possible to prevent undesired wear of various transport mechanisms such as other rollers and belts that are not subject to dressing, that is, dressing is unnecessary.

As the abrasive grains constituting the dressing portion 14, hard abrasive grains such as emery polishing paper, for example, white alundum, silicon carbide, diamond, etc. can be applied. The abrasive grains are bonded to a predetermined region on the surface of the substrate 12 with an adhesive such as an epoxy adhesive to form the dressing portion 14.

The dressing section 14 performs etching processing on the substrate 12 itself by a photo-etching technique,
It may be configured by forming irregularities on the surface of the substrate 12. Such a method is particularly effective when a metal material is used as the material of the substrate 12.

Even if the roller to be dressed is a rubber roller, it is formed by mixing particles of carbon black or silica as a reinforcing material. Therefore, when dressing such a rubber roller, the dressing portion 14 is used.
Wear progresses. Therefore, the dressing sheet 10
In order to maintain the above performance for a long time, the dressing sheet 10 in which stainless steel is adopted as the substrate 12 and diamond abrasive grains are dispersed and electrodeposited by the nickel electrodeposition method on the surface of the substrate 12 is optimal.

Therefore, in the third embodiment, a sheet-shaped dressing jig, for example, the dressing sheet used in the above-described second embodiment is adopted to efficiently remove the dirt on the separation roller portion 228. Is what you are trying to do.

That is, the control section 300 controls the drive of the separating section 112 based on the instruction to execute the dressing mode. More specifically, the control unit 300 controls the dressing sheet 40 to be the loading slot 102 of the automatic ticket gate 100.
Then, the dressing sheet 40 is transported toward the downstream side in the transport direction by rotationally driving the transport roller pair 224 and the transport belt pair 226 in the forward direction.

Then, the control unit 300 has the stopper unit 42.
Even if the intrusion of the paper is regulated by the inlet 102, the conveying roller pair 224, the conveying belt pair 226, and the return roller 228A and the feed roller 228B that form the separation roller unit 228 are further driven in the forward direction. At this time, the dressing section 14 of the dressing sheet 40 is in a state of being sandwiched by the separation roller section 228, and the cleaning section 16 is in a state of being sandwiched by the transport roller pair 224 and the transport belt pair 226.

As a result, the separation roller portion 228 is rotationally slid relative to the dressing portion 14, and the surfaces of the return roller 228A and the feed roller 228B are polished. At the same time, the pair of transport rollers 224 and the pair of transport belts 226 are slid relative to the cleaning unit 16 so that their surfaces are cleaned.

Then, the control unit 300 determines that the conveying roller pair 224 and the conveying belt pair 2 have been operated based on the elapse of a predetermined time.
26 and the separating roller portion 228 are driven to rotate in the opposite direction, so that the dressing sheet 40 is loaded into the loading port 102.
Discharge from.

By the steps described above, the automatic ticket gate 1
The dressing mode at 00 is terminated.

As described above, the dirt adhering to the rubber roller forming the separation roller portion is brought in from the tickets to be processed and an unspecified number of passengers, and the source of the dirt cannot be eliminated. . Therefore, in order to maintain the conveyance ability and the separation ability of the separation roller portion, it is necessary to take measures to remove the dirt adhering to the rubber roller,
Moreover, in the case of an automatic ticket gate, there is a demand for a method of removing dirt on the rubber roller on the machine in a short time.

According to the third embodiment, when the instruction to execute the dressing mode is received as necessary, the dressing sheet is inserted into the dressing sheet by inserting the dressing sheet from the insertion slot like the ticket. Intrusion of the stopper portion provided is regulated by the insertion port, and in this state, by driving another driving body with respect to the dressing sheet, dressing or cleaning of the driving body can be performed. In this way, it becomes possible to efficiently dress and clean the separating section on the automatic ticket gate in a short time.

As described above, in a sheet-shaped medium processing device such as an automatic ticket gate that processes tickets as sheet-shaped media, a dressing sheet having a dressing portion is rubbed on a driving body to be dressed, for example, a rubber roller. By moving it, it becomes possible to efficiently polish or dress the surface of the driving body. As a result, the shape of the driving body can be maintained, and at the same time, the carrying ability and the separating ability of the driving body can be maintained at sufficient performance.

Further, in the rubber roller pair arranged so as to face each other, it is possible to correct the imbalance between the rollers caused by the insufficient accuracy of the parallelism of the shafts or the swelling of the rubber rollers themselves.

Further, even if dirt such as grease that cannot be easily cleaned adheres to the surface of the driving body, the dirt can be removed by dressing the surface of the driving body, and the friction coefficient of the driving body is set to a predetermined value. Can be maintained at value.

Further, since the inside of the machine is dressed using the dressing sheet, it is not necessary to open and close the sheet medium processing device, and the driving body can be cleaned easily and in a short time. Therefore, anyone who is not a trained maintenance staff can carry out the inspection at the time of daily start-up inspection.

Further, since the dressing sheet is provided with the cleaning section, the rubber roller, the belt, the magnetic head, etc., which only needs to be wiped off a slight stain, can be easily cleaned in a short time.

The present invention is not limited to the above-described embodiments, and various modifications and changes can be made at the stage of carrying out the invention without departing from the spirit of the invention. Further, the respective embodiments may be carried out in an appropriate combination as much as possible, and in that case, the effect of the combination can be obtained.

For example, in the above-mentioned third embodiment,
Although the method of dressing the separating section has been described by taking an automatic ticket gate as an example of a sheet medium processing device, other sheet medium conveying devices that employ friction separating rollers, such as a mail sorting machine, a cash processing machine, a ticket issuing machine, and a card reading device. The same can be applied to machines and registers. Even in the case of a single roller instead of a pair, a similar in-machine dressing can be performed by using a dressing sheet provided with a polishing surface on one side and providing a counterpart component such as a pinch roller that can hold the dressing sheet. It goes without saying that you can do it.

[0087]

As described above, according to the present invention, dirt adhering to the roller surface can be removed in a short time, and the friction coefficient of the roller can be maintained at a high level.
A dressing sheet capable of preventing deformation of a roller due to swelling and a dressing method using the same can be provided.
