Description

  The present invention relates to a cleaning member for cleaning a conveyance path of a medium processing apparatus and a medium processing apparatus having a medium conveyance path.

  2. Description of the Related Art Conventionally, for example, in an automatic transaction apparatus as a medium processing apparatus, an optical sensor for detecting a banknote is disposed on a conveyance path for conveying a banknote as a medium. When this sensor is contaminated with paper dust or dust, or when a piece of paper remains on the conveyance path, it is necessary to clean the conveyance path. In such a case, conventionally, a patrol ticket is transported to remove paper dust and dust adhering to the sensor, while removing a piece of paper remaining on the transport path. As what discloses conveying a patrol ticket and cleaning a conveyance path, patent document 1 (Unexamined-Japanese-Patent No. 10-91840) is mentioned, for example.

The patrol ticket disclosed in Patent Document 1 has a structure in which a cloth as a cleaning material is attached to a base material having the same size and shape as a banknote, for example, a 10,000 yen banknote, and reciprocates the patrol ticket. By transporting, the sensor disposed in the transport path is cleaned. (See Patent Document 1, paragraph 0027, etc.)
Japanese Patent Laid-Open No. 10-91840

  However, in the conventional cleaning member (patrol ticket), the cleaning range is limited to a sensor provided so as to protrude into the conveyance path, and paper dust or dust or There has been a problem that a piece of paper cannot be completely removed by reciprocating conveyance of the cleaning member. If paper dust or dust remains, it may adhere to the sensor again, and if a piece of paper remains, it may cause a jam when the medium (banknote) is conveyed.

  Moreover, since the cleaning member (patrol ticket) disclosed in Patent Document 1 has the same shape as the medium (banknote), the width of the medium is shorter than the width of the conveyance path. As a result, a portion that cannot be cleaned is formed between the cleaning member and the widthwise end of the conveyance path. In order to solve this, the cleaning position of the cleaning member must be changed with respect to the transport path and cleaned and transported at least twice.

In order to solve the above-described problems, a cleaning member according to the present invention is a cleaning member for cleaning a transport path for transporting a medium by a transport unit, and includes a base material made of a flexible material and the transport unit in the base material. It consists of a cleaning material provided on both surfaces of the base material except for the opposing transport means facing portion, the width (C) of the cleaning member is substantially the same as the width (B) of the transport path, and The width (D) of the substrate-facing portion facing portion of the base material is the difference (B-C) between the width (B) of the transport path and the width (C) of the cleaning member. It is more than the added value .

  According to the cleaning member of the present invention, since the base material is provided with a high-friction flexible and stretchable cleaning material, paper dust and dust at a position deeper from the conveyance position of the medium can be removed. Is possible.

  Further, according to the cleaning member of the present invention, the length in the width direction of the base material is substantially the same as the width of the transport path, and the length is such that excessive resistance does not act on the end surface in the width direction of the base material during transport. By doing so, it is possible to satisfactorily clean the end portion in the width direction of the conveyance path with a small number of conveyances.

Furthermore, in the banknote storage part 3, if the banknote M inserted from the user P can be used as a withdrawal banknote, the banknote M is stored from the separating and feeding part 3a.

  During normal operation, when the user P selects the deposit transaction and inserts the banknote M into the customer service unit 2, the inserted banknote M is transported from the customer service unit 2 through the transport path 7 and sent to the discrimination unit 4. If it determines with it being usable for payment here, it will be sent to the banknote storage part 3 of a corresponding denomination and stored. Further, when withdrawing money to the user P, when the user P inputs a withdrawal amount, a bill M corresponding to the amount is paid out from the bill storage unit 3 and sent to the discrimination unit 4. If it is determined by the discrimination unit 4 that there is no problem with the withdrawal, it is transported through the transport path 7 and sent to the customer service unit 2. When the banknote M corresponding to the withdrawal amount is accumulated in the customer service unit 2, a shutter (not shown) is opened, and the user P takes out the banknote M.

  FIG. 2 is a schematic front view showing the conveyance path 7. In FIG. 2, upper transport rollers 11a and 11b and lower transport rollers 12a and 12b are rotatably provided in the transport path 7. The upper transport roller 11a is pressed against and opposed to the lower transport roller 12a, and the upper transport roller 11b is transported in the lower transport. It is in pressure contact with the roller 11b. The upper transport rollers 11 a and 11 b are attached to the shaft 13, and a gear 14 and a knob 15 are attached to the end of the shaft 13. The knob 15 is used when the conveyance path 7 is cleaned as will be described later.

  The lower conveying rollers 12 a and 12 b are attached to the shaft 16, and a gear 17 is attached to one end of the shaft 16. The gear 17 meshes with the gear 14 described above, and both shafts 13 and 16 are simultaneously rotated in opposite directions by one driving means.

  A conveyance guide 18 is provided in the conveyance path 7, and a conveyance region 20 in which the banknote M is conveyed is formed by the conveyance guide 18. The width B of the transport area 20 is formed to be sufficiently larger than the width of the banknote M. The conveyance guide 18 is provided with a detection sensor 21 for detecting the banknote M. The detection sensor 21 includes a light emitting element 21-1 and a light receiving element 21-2 that are disposed with the banknote M interposed therebetween.

  FIG. 3 is a perspective view showing transport rollers 11 and 12 as transport means. In FIG. 3, the banknotes M are transported in the direction of the arrow X by the upper transport rollers 11a and 11b and the lower transport rollers 12a and 12b rotating in the direction of the arrows, respectively. The conveyance rollers 11 and 12 are circular wheel-shaped components, and when the rotational force is transmitted to the shafts 13 and 16 passing through the center, the conveyance rollers 11 and 12 rotate. The peripheral speed of the transport rollers 11 and 12 is expressed by (number of rotations × roller diameter × circumferential ratio) per unit time. As shown in FIG. 2, the transport rollers 11 and 12 protrude into the transport area 20 and are disposed so as to be in contact with both front and back surfaces (in some cases, only one surface) of the banknote M transported through the transport area 20.

  The transport rollers 11 and 12 have elasticity, and the surface thereof is formed of a high friction material. When the transport rollers 11 and 12 rotate, friction is generated on the contact surface with the banknote M, and the banknote M is transported by the transport roller 11. , 12 and are transported together.

  FIG. 4 is a perspective view showing a conveying belt 22 as conveying means. The conveyance belt 22 as another conveyance means which conveys the banknote M is demonstrated. In FIG. 4, the conveyor belts 22a and 22b are stretched over pulleys 23a, 24a, 23b, and 24b arranged at positions separated from each other. Rotates. The outer surfaces of the conveyor belts 22a and 22b are formed of a high friction material and have a frictional force. As the conveyor belts 22a and 22b rotate, friction is generated on the contact surface with the banknote M, and the banknote M is transported.

  FIG. 5 is a front view showing the cleaning member 30 of the first embodiment, and FIG. 6 is a perspective view showing the cleaning member 30 of the first embodiment. In both figures, the cleaning member 30 includes a base material 31 and a cleaning material 32 erected on both surfaces of the base material 31. The base material 31 is formed of a flexible material, for example, paper or plastic, a film, or a fiber material, and is desirably a material that does not impair the function even when wet. The material of the cleaning material 32 has a high friction property and is made of a material that is flexible or stretchable / compressible. For example, mohair (long raising) is used.

  The cleaning material 32 is erected almost vertically on both surfaces of the base material 31. There are methods for attaching the cleaning material 32 to the base material 31 such as sticking with a double-sided tape, sticking with an adhesive, or sewing, but the transport path 7 of the automatic transaction apparatus 1 also has a curved portion. A method that does not impair flexibility as the cleaning member 30 is taken. The cleaning material 32 is attached to a predetermined position of the base material 31. That is, it is attached to all the front and back surfaces except the contacting portions as the portions facing the conveying rollers 11 and 12 or the conveying belt 22.

  Reference numeral 33 shown in FIGS. 5 and 6 denotes a contact portion as a portion of the base material 31 facing the transport rollers 11, 12 or the transport belt 22. The contact portion 33 is a contact portion that comes into contact with the base material 31 because it is transported by the transport rollers 11, 12 or the transport belt 22, and the cleaning material 32 is not erected on the contact portion 33.

  FIG. 7 is a perspective view showing a conveyance state of the cleaning member 30 by the conveyance rollers 11 and 12, and FIG. 8 is a front view showing a conveyance state of the cleaning member 30 by the conveyance rollers 11 and 12. FIG. 9 is a perspective view showing a conveyance state of the cleaning member 30 by the conveyance belt 22, and FIG. 10 is a front view showing a conveyance state of the cleaning member 30 by the conveyance belt 22. As shown in these figures, when the cleaning member 30 is transported, the transport rollers 11a, 11b, 12a, and 12b are transported in contact with the contact portion 33 of the cleaning member 30, and the transport belts 22a, 22b, 25a, and 25b are transported. In this case as well, the cleaning member 30 is conveyed in contact with the contact portion 33. The height of the cleaning member 30 is substantially the same as the height of the transport area 20 of the banknote M. Since the cleaning material (mohair) 32 extends from the contact position of the transport roller or the transport belt with the base material 31 to the transport guide 18 in the back side (vertical direction in FIGS. 8 and 10), the cleaning material (mohair) 32 is deepened in the transport region 20. Can be cleaned.

As described above, the conveying roller or the conveying belt can be arranged without considering the thickness of the cleaning material 32 by standing the cleaning material 32 on the base material 31 while avoiding the contact portion 33.

  Next, the width of the contact portion 33 will be described. FIG. 11 is an explanatory diagram for explaining the width of the contact portion 33 of the cleaning member 30. In FIG. 11, the width of the contact portion 33 of the cleaning member 30 is determined by the widths of the transport rollers 11 a and 11 b, the width of the transport region 20, and the width of the cleaning member 30. When the width of the transport rollers 11a and 11b is A, the width of the transport region 20 is B, and the width of the cleaning member 30 is C, the width D of the contact portion 33 is set as D ≧ A + (B−C). With this dimension setting, even when the cleaning member 30 approaches one end of the transport region 20, the transport rollers 11 a and 11 b do not come into contact with the cleaning material 32.

  The width C of the cleaning member 30 is set to be approximately the same as the width B of the transport region 20, but if it is completely the same, the end face of the cleaning member 30 and the transport guide that forms the transport region 20 rub against each other and become resistance. For this reason, the end face in the width direction of the cleaning member 30 is set to be short enough to prevent resistance.

  Moreover, the height of the cleaning member 30 including the thickness of the base material 31 is set to be substantially the same as the height of the transport region 20 as described above. Accordingly, the cleaning material 32 can reach the back side from the contact portion 33, that is, the height at which the banknote M does not reach when the banknote is transported, and thus the cleaning can be performed up to these positions.

  Next, operation | movement in the case of cleaning the cleaning conveyance path 71 of the automatic transaction apparatus 1 using the cleaning member 30 of 1st Embodiment is demonstrated. FIG. 12 is a configuration diagram illustrating the automatic transaction apparatus 1 that performs cleaning using the cleaning member 30. When a sensor detection failure occurs due to a jam of the banknote M or dust accumulation, the cleaning conveyance path 71 that needs to be cleaned out of the conveyance path 7 is cleaned. In this case, the maintenance staff inserts the cleaning member 30 from the insertion port 71-1 corresponding to the cleaning conveyance path 71. After the insertion, the maintenance staff manually rotates the knob 15 shown in FIG. All the conveyance rollers 11 and 12 in the cleaning conveyance path 71 are interlocked, and by rotating the knob 15, the cleaning member 30 is conveyed from the insertion port 71-1 to the extraction port 71-2. The inside of the cleaning conveyance path 71 is cleaned by the passage of the cleaning member 30, and when the cleaning member 30 reaches the outlet 71-2, the maintenance staff takes out the cleaning member 30.

  The removed cleaning member 30 can be washed and reused. When paper is used for the base material 31, it can be reused by washing by dry cleaning, for example. Further, when a plastic, film or fiber material is used for the base material 31, it can be washed with water.

  Paper powder and dust, which are powders of the banknote M, accumulate in the conveyance path 7 of the automatic transaction apparatus 1. Detection sensors 21 that detect banknotes M are arranged at a plurality of locations on the conveyance path 7, and dust or the like adheres to the detection sensor 21, thereby causing a malfunction. The malfunction of the detection sensor 21 can be prevented by periodically cleaning the conveyance path 7.

  When performing maintenance at the site where the automatic transaction apparatus 1 is installed, the apparatus cannot be disassembled on the spot. For this reason, removing dust and paper dust in the transport path 7 is a time-consuming operation. In the present embodiment, it is possible to perform cleaning only by passing the cleaning member 30 once through the conveyance path 7, and therefore, the cleaning operation can be performed in a very short time.

  Further, since mohair or the like is erected as the cleaning material 32 and can be cleaned by entering the back side of the transport region 20 of the transport path 7, not only the detection sensor 21 but also the corner of the inner wall of the transport guide 18 of the transport path 7. It is possible to clean up. Furthermore, when mohair is used, dust and dust removed from the inside of the conveyance path 7 are collected in itself, so that it can be cleaned without being left behind. Further, according to the first embodiment, the cleaning material 32 is attached to the base material 31 while avoiding the contact portion 33 with the transport rollers 11, 12 or the transport belt 22, so that the transport roller 11 by the cleaning material 32 is used. , 12 or the conveyor belt 22 can be eliminated.
