Definitions

  • the present invention relates to a coin hopper that separates and dispenses coins one by one by means of a rotary disc.
  • the present invention relates to a coin hopper that prevents occurrence of coin bridges (the phenomenon that coins clump to form a space above the rotary disc) by means of simple equipment.
  • coin bridges the phenomenon that coins clump to form a space above the rotary disc
  • the term "coin” used herein is a collective term for circular discs such as currency and tokens.
  • the first conventional art faces the problem that a coin bridge cannot be prevented when a coin bridge is formed using a wall surface of storage bowl other than the rotary circular plate as a scaffold.
  • the second conventional art faces the problem that the position of the wall surface which is elastically supported balances with the weight of coin or the like so that it becomes substantially a stationary wall and fails to eliminate coin bridges.
  • the third conventional art is advantageous in that the coin being in contact with a lower wall surface of holder is actively moved because the lower wall surface moves along a predetermined length, so that a scaffold for coin bridge is not formed and hence coin bridge does not occur.
  • the belt is disposed right above the rotary disc, and receives weights of plenty of coins, a problem of large consumed energy for driving the belt arises.
  • the belt is driven by a common driving mechanism for the rotary disc, the belt is attached to an upper part of the rotary disc integrally with the rotary disc.
  • FR-A-2199602 discloses an element rotating about an axis parallel to that of the rotary coin-feeding disc, the function of which however is to singulate coins to prevent jamming at the point of exit of coins from the hopper. This is not concerned with solving the problem addressed by the present invention.
  • EP-A-1544805 describes a coin hopper which includes an agitator. Smooth agitation and efficient transport of coins is promoted by setting the rotation direction of the agitator as the same direction as the rotary disc.
  • GB-A-2355104 also discloses a coin hopper having a stirring body above the top surface of the rotary coin feeding disc at or close to the axis of rotation of the disc so as to eliminate blockage of the coin dispensing apparatus.
  • a coin hopper which dispenses coins one by one via a rotary disc disposed below a coin storage bowl, wherein an outer circumferential face of a stirring member adapted to rotate around an axial line which is substantially parallel with a rotation axial line of the rotary disc forms a part of an inner wall of the storage bowl.
  • the present invention prevents coin bridges in a storage bowl without significantly increasing the energy consumption.
  • the present invention also provides a coin hopper having a coin bridge preventing function that enables easy response to troubles of rotary disc.
  • a part of the outer circumferential face of the stirring member forms a part of an inner wall of the storage bowl.
  • the stirring member is rotated about an axial line which is substantially parallel with the rotation axial line of the rotary disc.
  • the coin in the storage bowl that is in contact with the circumferential face of the actively moving stirring member is actively moved by the friction force with the stirring member.
  • the stirring member extends linearly from bottom to top of the storage bowl.
  • the stirring member will not be subject to most of the weight of the coins in the storage bowl because it is in linear contact with the coins.
  • the stirring member rotates about an axial line which is substantially parallel with the rotation axial line of the rotary disc.
  • This provides an advantage of applicability in a small coin hopper because only a space that is enough for the stirring member to rotate about the axial line is required.
  • the stirring member is preferably in the form of a drum in which diameter at the center is larger than those at both ends in the coin hopper.
  • the stirring member is in the form of a drum in which diameter at the center is larger than those at both ends, the coin is moved two-dimensionally because it receives a moving force toward the rotation axial line of the rotary disc, as well as a moving force of a lateral direction which is parallel with the rotary disc, due to rotation of the stirring member.
  • the moving direction of the coin is diversified so that occurrence of coin bridge is effectively prevented.
  • the circumferential face of the stirring member is preferably formed with a spiral groove in the coin hopper.
  • a coin is pushed down or up by a wall defining the spiral groove by rotation of the stirring member, while receiving a moving force in the lateral direction which is parallel with the rotary disc.
  • the coin is moved three-dimensionally because it is moved in the vertical direction while moved two-dimensionally as described above, so that the moving direction of coin is diversified and an advantage of efficiently preventing a coin bridge is provided.
  • the rotary disc may be disposed at a slant to the horizontal, and the stirring member extends from the lowermost end of the rotary disc.
  • the storage bowl may have a cylindrical part extending along the axial line of the rotary disc, and an increased amount storage part having a slant bottom face which is substantially parallel with the rotary disc, and the circumferential face of the stirring member is arranged in the inner wall surface of the cylindrical portion above an extended line of the slant bottom face in the coin hopper.
  • a part of a wall surface of the cylindrical part is formed by the circumferential face of the stirring member.

  • the storage bowl When a coin is nipped by the rotary disc, the storage bowl is removed from the rotary disc side prior to conducting an operation.
  • the stirring member is rotatably attached to the storage bowl, and connected to the driving unit of the rotary disc via a clutch, it can be removed integrally with the storage bowl from the rotary disc side.
  • the storage bowl when the storage bowl is attached to the rotary disc, the storage bowl can be attached to the rotary disc side by connecting the clutch, so that easy attachment/detachment is enabled.
  • the clutch may be a meshing clutch which is axially connectable and disconnectable in the coin hopper.
  • the meshing clutch When the storage bowl is detached from the rotary disc side, the meshing clutch can be disconnected by axially leaving and the meshing clutch can be connected by axially approaching.

  • a lateral stirring member is provided in addition to the stirring member.
  • a coin bridge is prevented by movement in the circumferential direction of the rotary disc or movement in the vertical direction of the wall surface of the storage bowl through rotation of the stirring member about axial line which is parallel with the axial line of the rotary disc.
  • the lateral stirring member rotates about an axial line which is substantially orthogonal to the wall surface of the storage bowl, the coin that contacts therewith receives a lateral rolling force above the rotary disc.
