  The present invention relates to a roller rubber that can be attached to and detached from a roller mechanism that separates a medium, and a medium processing apparatus equipped with the roller rubber.

  In recent years, financial services provided by ATMs (automated teller machines) have a tendency to become longer, such as 24-hour operation and holiday operation. Such ATM stores a sufficient amount of banknotes so that it can be withdrawn according to the operating time. FIG. 8 shows the appearance of a general ATM. Reference numeral 21 denotes an ATM main body. A passbook insertion port 22, a card insertion port 23, a customer operation display unit 24, and a customer service port 25 are provided on the front surface of the main body 21. A customer stands in front of the main body 21 and inserts a passbook or card from the passbook insertion port 22 or the card insertion port 23 according to the procedure displayed on the customer operation display unit 24, and then the banknotes possessed from the customer service port 25 according to the procedure. Or withdrawing the banknotes accumulated in the customer service port 25.

  FIG. 9 shows a configuration diagram of the structure of the main body 21 as viewed from the side. 26 is a temporary storage unit for accumulating and temporarily accumulating banknotes inserted by customers into the customer service port 25, 27 is a reject storage for accumulating banknotes determined to be defective banknotes by a not-shown discrimination unit, and 28 is It is a denomination banknote storage in which the denomination part identifies the denomination of the banknote and the banknote is distinguished and stored for each denomination type, for example, 10,000 yen, 1,000 yen, 5,000 yen, etc. A plurality of banknote storages are prepared for each denomination and sorted according to the result of denomination discrimination. Further, when a predetermined amount of banknotes is withdrawn by a customer transaction, a banknote of an amount desired by the customer is dispensed from the delivery service port 25 as necessary from the denomination-type banknote storage. A banknote separating mechanism 30 is provided at the entrance of each storage of the denominated banknote storage 28 and the stored banknotes are separated and fed out by the operation of the apparatus.

  In the above apparatus, if the frictional force of the roller rubber 1 mounted on the roller portion 13a is reduced, the separation force of the banknotes is reduced, causing double sheet feeding and jamming. The roller rubber 1, which has reached the end of its life due to long-term use and whose frictional force has deteriorated, needs to be replaced periodically. However, when replacing the roller rubber 1, parts around the rotating shaft of the roller portion 13a must be removed, and the work takes time. It was a burden.

  In order to solve the above-described problems, in the present invention, as a first aspect of the present invention, in a medium treatment apparatus for separating a medium by rotating a roller equipped with a roller rubber, a groove and two end portions are formed in the center of the roller rubber in the width direction. The structure was provided, and the belt rubber was stretched along the groove portion to fix the roller rubber to the roller portion.

  According to a second aspect of the present invention, there is provided a medium treatment apparatus for separating a medium by rotating a roller equipped with a roller rubber, wherein the roller rubber is configured by providing two end portions and two engaging portions at the two end portions. The stoppers are fixed to the roller by engaging with each other.

  According to a third aspect of the present invention, there is provided a medium treatment apparatus for separating a medium by rotating a roller equipped with a roller rubber. The roller rubber has two ends, a protrusion at one end, and a recess at the other end. The protrusion and the recess are connected to each other so as to be fixed to the roller.

  According to the above invention, it is possible to easily attach the roller rubber without removing the peripheral parts of the roller portion, so that it is possible to reduce the man-hour for ATM maintenance work.

  Examples 1 to 3 which are the best modes for carrying out the present invention will be described below.

  The roller rubber according to the first embodiment of the present invention is provided with a groove portion in the center in the width direction, and by cutting a part of the roller rubber on the circumference to form two end portions. After the end portion is gripped and wound around the roller portion, a belt separately provided along the groove portion of the roller rubber is stretched to be mounted and fixed on the circumference of the roller portion.

  The configuration of this embodiment will be described. As described above, the separation roller 13 can swing above the stacked banknotes B by the swing mechanism A of the banknote separation mechanism 30 of FIG. The roller rubber 1 is mounted around the roller portion 13 a of the separation roller 13. At the time of banknote separation, when the swing mechanism A is operated so that the member approaches the banknote B, the separation roller 13 rotates and contacts the stacked uppermost banknote B, and the banknote B is pulled by friction of the roller rubber 1. One sheet is separated and the bill B is sent out to the transport path by the rotation of the transport roller 14. FIG. 1A is a view showing a roller rubber 1 of this embodiment. The roller rubber 1 is formed in an annular shape, and a part of the circumference is cut. Thereby, two end portions 3 and 4 are formed. Further, since the roller rubber 1 has an appropriate softness when being removed from the roller portion 13a, the gap between the end portions 3 and 4 can be determined by gripping the end portions 3 and 4 and moving them to the left and right. Can be opened easily. A groove 2 is formed around the roller rubber 1 at the center in the width direction. The roller rubber 1 is formed so that the inner diameter of the roller rubber 1 is smaller than the outer diameter of the roller portion 13a in a state in which the end portions 3 and 4 are attracted to each other to the extent that they are in contact with each other.

  FIG. 1B shows a cross section of the roller rubber 1 of FIG. 1A viewed from a direction orthogonal to the rotation axis direction of the roller portion 13a. Surfaces 5 on which the roller rubber 1 comes into contact with the banknotes are formed on both sides of the groove portion 2, and anti-slip nicks are applied to prevent slippage when feeding the medium. FIG. 2 shows a belt 6 used for fixing the roller rubber 1 to the roller portion 13a. Terminals 7 and 8 made of metal are provided at both ends of the belt 6. One terminal 7 is provided with a protrusion 7a, and the other terminal 8 is provided with a hole 8a. The protrusion 7a is formed thinner than the width of the belt 6, and the tip is bent at a right angle. The length of the belt 6 is substantially equal to the circumferential length of the roller rubber 1. Further, the surface of the belt 6 that comes into contact with the rubber roller 1 is subjected to surface processing such as roughening and fine notches so as to have higher friction than the opposite surface.

  FIG. 3 shows a structure in which the roller rubber 1 and the belt 6 are mounted on the roller portion 13a as viewed from the rotation axis direction of the roller portion 13a. When attaching the roller rubber 1, the end portions 3 and 4 are gripped and moved to the left and right to open a gap between the end portions 3 and 4, for example, one end portion, for example, the end portion 3 and the lower portion of the roller portion 13a It inserts in the direction orthogonal to the rotating shaft of the roller part 13a in the gap formed between the uppermost medium. One end 3 inserted from the rear of the lower portion of the roller portion 13a is pulled out, and the roller rubber 1 is pulled out to a position about half the length.

  One end portion 4 of the roller rubber 1 remaining in front of the roller portion 13a is supported by another hand, the end portion 3 is gripped by one hand, and the end portion 4 is gripped by the other hand. 3 and 4 are pulled up above the roller portion 13a, and the end portions 3 and 4 are brought close to each other above the roller portion 13a so that the roller rubber 1 is wound around the roller portion 13a. Thereby, the roller rubber 1 maintains its shape due to its own elasticity and is temporarily fixed on the circumference of the roller portion 13a.

  Thereafter, the protrusion 7 a and the terminal 7 are inserted below the roller portion 13 a and the roller rubber 1 in the same manner as the roller rubber 1, and the belt 6 is wound around the roller rubber 1 along the groove portion 2. Above the roller belt 1, the protrusion 7a and the hole 8a are brought close to each other by hand and the belt 7 is pulled. As a result, the roller rubber 1 expands, the inner diameter thereof becomes substantially the same as the outer diameter of the roller portion 13a, and the end portions 3 and 4 are attracted to come into contact with each other. Thereafter, a portion bent at a right angle at the tip of the protrusion 7a is inserted into the hole 8a, and the belt 6 is fixed. The bent portion of the tip of the protrusion 7a that penetrates the hole 8a during fixing is sandwiched in the gap between the ends 3 and 4 of the roller belt 1. As a result, the roller rubber 1 is brought into close contact with the contact surface with the roller portion 13a and is fixed without any play.

  The belt 6 is stretched on the circumference of the roller rubber 1 along the groove portion 2 of the roller rubber 1, and the width of the belt 6 is slightly narrower than the width of the groove portion 2, so that the belt 6 is completely of the groove portion 2. Even when the roller rubber 1 comes into contact with the bill B, the belt 6 does not come into contact with the medium at the time of separation, and the tip of the protruding portion 6a also does not protrude from the surface of the roller rubber 1. The separation operation can be performed smoothly without interfering with the separation. Further, since the surface of the belt 6 that contacts the rubber roller 1 is formed with higher friction than the surface on the opposite side, no slip occurs on the contact surface between the roller rubber 1 and the belt 6, and the roller rubber is being fed while the bill B is being fed. 1 and the belt 6 are not loosened.

  In the first embodiment of the present invention described above, the belt 6 provided separately from the roller rubber 1 is fixed. However, the belt and the roller rubber 1 may be integrally formed.

  In the second embodiment of the present invention, two locking portions are provided at the end portions 3 and 4 of the roller rubber 1 of the first embodiment, and the two locking portions are locked to each other so as to be fixed around the roller portion 13a. It is a thing. In this embodiment, the belt 6 is not used, and the roller rubber 1 can be fixed to the roller portion 13a alone.

  FIG. 4 is a view showing the structure of the roller rubber 1 according to the second embodiment. Reference numerals 9 and 10 denote locking portions made of metal fittings attached to the end portions 3 and 4, respectively. As in the first embodiment, the roller rubber 1 is formed so that the inner diameter of the roller rubber 1 is smaller than the outer diameter of the roller portion 13a when the end portions 3 and 4 are pulled toward each other so that the end portions 3 and 4 are in contact with each other. When the roller rubber 1 of this embodiment is mounted, the roller rubber 1 is wound around the roller portion 13a and temporarily fixed to the roller rubber 1 body as in the first embodiment, and then the end portions 3 and 4 are pulled to extend the roller rubber 1 and to engage. Stops 9 and 10 are locked together. The inner diameter of the roller rubber 1 is the same length as the outer diameter of the roller portion 13a, and the resulting pulling force causes the locking portions 9 and 10 to be pulled to the left and right, thereby fixing the roller rubber 1 in close contact with the roller portion 13a. The

  In Embodiment 3 of the present invention, protrusions and recesses are provided at the end portions 3 and 4 of the roller rubber 1 of Embodiment 1, and the protrusions are press-fitted into the recesses and connected. The roller rubber 1 is attached to the roller portion 13a alone without the need for the belt 3. FIG. 5 is a view showing the roller rubber 1 of the third embodiment.

  Reference numeral 11 denotes a recess provided at the end 3 of the roller rubber 1. The diameter in the vicinity of the outlet of the recess is formed to be smaller than the diameter of the tip portion of the protrusion 12 described later. Reference numeral 12 denotes a protrusion provided on the other end 4, and the tip of the protrusion 12 is formed in a spherical shape having a diameter larger than that of the root. The roller rubber 1 is formed so that the inner diameter of the roller rubber 1 is smaller than the outer diameter of the roller portion 13a in a state in which the roller rubber 1 is pulled to the extent that the end portions 3 and 4 are in contact with each other. In fixing the roller rubber 1 to the roller portion 13a, after the roller rubber 1 is wound around the roller 13a, the two end portions 3 and 4 are pulled, the projection portion 12 is pressed against the recess portion 11, and force is applied by hand. Is added, the head is pushed and pushed into the recess.

  The inner part of the recess is formed so as to have a spherical space with the same diameter as the spherical part at the tip of the protrusion 12, and as a result of being pushed in by hand, the protrusion 12 and the recess 11 are brought into close contact with each other. Connected. When the protrusion 12 and the recess 11 are connected, the main body of the roller rubber 1 is extended, and the inner diameter thereof is substantially the same as the outer diameter of the roller part 13a. Due to the above structure, the protrusion 12 and the recess 11 do not come out unless they are pulled with a certain amount of force or more, so that when the banknote B is separated, even if an unexpected force is applied to the roller rubber 1, it easily comes off. There is nothing. Further, since an appropriate tensile force is generated by the extension of the roller rubber 1, the roller rubber 1 is fixed in close contact with the roller portion 13a.
