Definitions

  • the present invention relates to a sheet processing apparatus.
  • Patent Literature (hereinafter referred to as "PTL") 1 discloses a sheet storage mechanism for storing a sheet by winding a tape and the sheet around a drum.
  • PTL 1 discloses a technique of controlling a drum driving source such that a tape speed detected by a tape speed detection unit is constant.
  • PTL 1 also discloses a technique of controlling, based on the tape speed detected by the tape speed detection unit and a reel speed detected by a reel detection unit, a reel driving source such that the tape has a certain level of tension.
  • PTL 2 discloses a method of controlling a banknote store comprising at least one winding means and at least one elongate support means
  • PTL 3 discloses a paper sheet feeding device wherein a pair of guide members are arranged separated from each other in a mounting part
  • PTL 4 discloses a paper money temporary storage apparatus provided with one recycling roller assembly.
  • banknotes with a security thread and a banknote with a seal have been used.
  • Such banknotes are not uniform in thickness.
  • a thick portion and a thin portion exist in one banknote.
  • the shape of a roll may be an inappropriate shape that is not a cylindrical shape; for example, the shape of the roll may be a truncated cone shape.
  • the sheet storage mechanism disclosed in PTL 1 is incapable of detecting that the shape of a roll formed from the tape and sheets wound around the drum is an inappropriate shape.
  • a sheet processing apparatus is a sheet processing apparatus comprising: a storage unit that stores a sheet and feeds the sheet stored; and a control unit that controls the storage unit, characterized in that the storage unit comprises: a first reel around which a first tape is wound; a second reel around which a second tape is wound; a drum that winds the sheet together with the first tape drawn from the first reel and the second tape drawn from the second reel to form a roll; a first sensor that detects movement of the first tape; and a second sensor that detects movement of the second tape, a position at which the first tape is wound around the drum and a position at which the second tape is wound around the drum are different from each other in an axial direction of the drum, and the control unit controls the storage unit based on a detection result of the first sensor and a detection result of the second sensor.
  • the control unit is capable of obtaining, based on the detection result of the first sensor, a size of the roll at the position at which the first tape is wound. Further, the control unit is capable of obtaining, based on the detection result of the second sensor, a size of the roll at the position at which the second tape is wound. Therefore, the control unit is capable of detecting that the shape of the roll is an inappropriate shape that is not a cylindrical shape being substantially uniform in diameter. In addition, when detecting that the shape of the roll is an inappropriate shape, the control unit is capable of controlling the storage unit suitably to that situation. It is thus possible, for example, to prevent deterioration of the situation or improve the situation.
  • the sheet includes a banknote, check, ticket, coupon, and voucher.
  • the first tape and the second tape may be wound around the drum while being in contact with the same surface of the sheet wound around the drum.
  • the storage unit may comprise a third reel around which a third tape is wound, and a fourth reel around which a fourth tape is wound.
  • the third tape is wound around the drum in such a manner as to overlap the first tape
  • the fourth tape is wound around the drum in such a manner as to overlap the second tape.
  • the third tape is wound around the drum in a state where the sheet is sandwiched between the third tape and the first tape
  • the fourth tape is wound around the drum in a state where the sheet is sandwiched between the fourth tape and the second tape.
  • the first tape and the second tape may be wound around the drum while in contact with respective different surfaces of the sheet wound around the drum.
  • the first tape and the second tape do not overlap each other, but sandwiches the sheet from above and below. Therefore, when the drum, the first reel, and the second reel rotate reversely to unwind the roll, and the sheet comes out of the roll, the sheet cannot remain attached to the roll. In other words, it is possible to smoothly discharge the sheet from the storage unit.
  • the storage unit may comprise a fifth reel around which a fifth tape is wound.

  • the storage unit may comprise a fifth sensor for detecting the movement of the fifth tape. By using three of the first sensor, the second sensor, and the fifth sensor, it is possible to detect the shape of the roll more accurately. It is possible to detect that the roll has a barrel shape, for example.
  • the storage unit may comprise at least one of a first roller and a second roller, the first roller being a roller which is in contact with the first tape stretched between the first reel and the drum and rotation of which is detected by the first sensor, the second roller being a roller which is in contact with the second tape stretched between the second reel and the drum and rotation of which is detected by the second sensor.
  • the first roller may be disposed to be in contact with the first tape on a first tape path between the first reel and the drum along which the first tape is drawn from the first reel and reaches the drum.
  • the second roller may be disposed to be in contact with the second tape on a second tape path between the second reel and the drum along which the second tape is drawn from the second reel and reaches the drum.

  • the storage unit comprises the second roller, and the second sensor detects the rotation of the second roller. Accordingly, the second sensor is capable of reliably detecting the movement of the second tape.
  • At least one of the first tape and the second tape may be a tape that is given a repetitive mark throughout its length.
  • the mark can be given by printing.
  • the mark can also be given by forming the tape from a colored material.
  • the first sensor may be a sensor that reads the mark given to the first tape.
  • the second sensor may be a sensor that reads the mark given to the second tape.
  • the amount of movement of the tape can be detected based on the number of passed marks.
  • the moving speed of the tape can be detected based on the moving speed of the passed mark or the number of passed marks per unit time.
  • the first sensor may be disposed at a position adjacent to the first tape stretched between the first reel and the drum, and the second sensor may be disposed at a position adjacent to the second tape stretched between the second reel and the drum.
  • the first sensor may be disposed at a position adjacent to the first tape path and the second sensor may be disposed at a position adjacent to the second tape path.
  • Such sensors are capable of detecting the movement of the tapes without making contact with the tapes.
  • At least one of the first sensor and the second sensor may be a sensor for detecting the amount of movement of the tape.

  • the first reel may be driven by a first motor
  • the second reel may be driven by a second motor.
  • the second motor is a different motor from the first motor. That is, the first reel and the second reel may be driven by the separate motors.
  • a case is considered where a sheet is to be wound further in a state in which the roll has the shape of a truncated cone, specifically, in a state in which the diameter of the roll at the position at which the first tape is wound (hereinafter, sometimes referred to as the first position) is larger than the diameter of the roll at the position at which the second tape is wound (hereinafter, sometimes referred to as the second position).
  • the first position the diameter of the roll at the position at which the first tape is wound
  • the second position the diameter of the roll at the first position
  • the first motor and the second motor are driven so that the tension applied to the first tape is greater than the tension applied to the second tape.
  • the degree of increase in the diameter of the roll at the second position can be greater than the degree of increase in the diameter of the roll at the first position. That is, it is possible to gradually change the truncated cone shape into the cylindrical shape.
  • the first reel and the second reel may be configured to be rotatable independently of each other by a single motor. That is, the motor may be configured such that the rotation of the single motor is transmitted via a transmission mechanism to the first reel and second reel at respective different transmission ratios.

  • the first reel and the second reel may be coaxially arranged. With such an arrangement, it is possible to equalize the distance from the first reel to the drum and the distance from the second reel to the drum, and thus to adjust the tension of the first tape and the tension of the second tape in the same manner.
  • the first reel and the second reel may be arranged such that the axis of the first reel and the axis of the second reel are on respective different straight lines. With such an arrangement, it is possible to increase the degree of freedom in the layout of the first reel and the second reel, and thus to optimize the layout of elements constituting the storage unit.
  • the drum may be driven by a drum motor.
  • the drum motor is a different motor from the first motor for driving the first reel and the second motor for driving the second reel. With this configuration, it is possible to drive the drum independently of the first reel and the second reel. Driving the drum independently of the driving of each of the reels makes it possible to finely adjust the tension applied to the first tape and the second tape.

  • the transport orientation may be a concept including the position of the transported sheet in the width direction of the transport surface (in other words, in a direction orthogonal to the transport direction).
  • the transport orientation may be a concept including an inclination of the sheet (whether or not the sheet is skewed) with respect to the transport direction.
  • the transport orientation may be a concept including a relationship between the long edge and the short edge of a rectangular sheet and the transport direction (whether so-called short-edge leading transport or long-edge leading transport).
  • the transport orientation relates to the position, in the axial direction of the drum, of a thick portion or a thin portion of a sheet not uniform in thickness during winding of the sheet around the drum.
  • the recognition unit may recognize at least one of the denomination, fitness, authenticity, or degree of soiling of the banknotes.

  • the control unit may control the storage unit based on whether or not the ratio between the diameters or the ratio between the radii exceeds a predetermined threshold.
  • the predetermined threshold may be changed according to a change in size of the diameter or the radius of the roll. For example, the difference of 1 cm between the diameter at the first position and the diameter at the second position is assumed. With respect to this value of 1 cm, it is indicative that the truncated cone shape is more distinctive when the diameters of the roll are smaller than when the diameters of the roll are larger.

The same applies to the radius.
  • the predetermined threshold may be set small when the diameters or the radii of the roll are small, or may be set largely when the diameters or the radii of the roll are large. Further, when it is to be determined whether or not the ratio between the diameters or the ratio between the radii exceeds a predetermined threshold, the predetermined threshold may be set small when the diameters or the radii of the roll are small, or may be set largely when the diameters or the radii of the roll are large.

Prohibition of the storage of such banknotes makes it possible to prevent the shape of the roll from becoming an inappropriate shape such as a truncated cone shape, or to prevent an increase in the degree of such a shape. Determination of whether or not the denomination is a predetermined denomination can be made based on a recognition result of the recognition unit.

The slippery surface brings about a lower friction coefficient of the sheet. The sheet having a low friction coefficient is likely to slip with respect to the tape and other sheets with which the sheet having a low friction coefficient is in contact in the roll. Therefore, when a sheet soiled to a great degree is wound in the case where the roll has a truncated cone shape, the inner side and the outer side of the roll with respect to the sheet soiled to a great degree serving as a border are displaced from each other in the axial direction of the roll, and in some cases, the roll may collapse.
