DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for transporting coins, bills, cards, and other plate-like members against a smooth conveying road surface with a straight portion of a belt and sliding the belt on the conveying road surface. The present invention relates to a transfer device for a plate-shaped member which increases a take-in force at an upstream pulley in a transfer direction and a sending output at a downstream pulley to improve transfer reliability.

[0002]

2. Description of the Related Art A conventional example will be described with reference to the drawings. FIG. 2 is a side view of one conventional example, and FIG. 3 is a plan view thereof, which are common to the later-described embodiments. In these figures, a coin 30 as a plate-like member is conveyed rightward by a round belt 3 on a conveying road surface 4. That is, the round belt 3 is wound around each of the upstream and downstream pulleys 27 (indicated by parentheses in the figure) related to the conveyance, and the lower straight portion moves close to and parallel to the conveyance path surface 4. The pulley 27 on the downstream side is driven by the motor 10 and is fixed to the shaft 8 via a gear without a reference numeral, and is driven to rotate in the direction of the arrow. The shaft 8 is connected to the pulley 27 on the downstream side.
Is positioned so that the gap between the outer peripheral surface of the belt 3 and the transport path surface 4 is less than the thickness of the coin 30. Further, a shaft 6 is fixed to the left end of an arm 9 swingably supported by the shaft 7, and an upstream pulley 27 is attached as a driven side so as to be rotatable around the shaft 6. In addition,
In FIG. 2, a counterclockwise bias is applied to an arm 9 around a shaft 7 by a torsion spring (not shown), and the arm 9 is positioned by a stopper.
Is adjusted so that the gap in the initial state between the outer peripheral surface and the transport path surface 4 is less than the thickness of the coin 30. Therefore, the lower straight portion of the round belt 3 moves to the right side in proximity to and parallel to the conveyance path surface 4 at an interval less than the thickness of the coin 30.

In this case, coins 30 classified by denomination in the previous process slide down from a left chute (not shown) and are fed into this conventional example. Coins sent in 30
Is slid on the conveying road surface 4 and is taken into the pulley 27 on the left side of the round belt 3 by being pressed against the conveying road surface 4 by the round belt 3 and subsequently conveyed. , And passed to a post-process not shown. The round belt 3 and the pulley 27 will be described in more detail with reference to FIG. FIG. 5 is a front view including a related part of a pulley in one conventional example. In FIG.
The pulley 27 has a winding portion 27a having a semicircular groove on the outer peripheral surface,
Each disk-shaped flange 27b is sandwiched from both sides. The diameter of the flange 27b is approximately equal to the distance between the centers of the semi-circular grooves of the wrap 27b. Therefore, only the outer peripheral surface of the wound round belt 3 is pressed and brought into contact with the coin 30.

Here, as the plate-shaped member to be conveyed, there are, for example, bills and cards in addition to the coins 30. In addition, ordinary coins 30 are conveyed by a method of being sandwiched between a pair of belts that move in the same direction in opposition to each other.
However, the overall transport system configuration, space,
Due to restrictions on cost and the like, there are many methods in which a smooth conveying path surface is used instead of one lower belt as in this conventional example. By the way, in the round belt 3, since there is a possibility of slipping on the semicircular groove surface of the pulley 27, a set of a toothed belt and a toothed pulley is used particularly when it is desired to sufficiently provide a conveying force. FIG. 6 is a perspective view of a toothed pulley and a toothed belt in another conventional example. In FIG. 6, a toothed belt 29 is wound around a toothed pulley.

[0005]

In one conventional example and another conventional example, the round belt 3 and the gear belt 29 contact the coin 30.
There is a problem that the capturing force and the sending output are weakened because only a part of the outer peripheral surface is used, and the capturing and sending are unstable because the force is applied to only one location. In particular, as in the conventional example, when one is the conveying road surface 4 and has no conveying force itself, and only the frictional force based on the pressing of the round belt 3 in a narrow area is the only take-in force and sending output Appears remarkably. In addition, if the take-in force is weak, the take-in becomes uncertain, and the receiving direction is shifted, which may hinder subsequent conveyance. If the sending power is weak, the sending direction is shifted, which may hinder delivery to the subsequent process. There is. in short,
As a result, the reliability related to the transportation is reduced.

SUMMARY OF THE INVENTION The object of the present invention is to solve the above problems of the prior art, and to increase the take-in force at the location of the upstream pulley in the transport direction and the sending power at the location of the downstream pulley. An object of the present invention is to provide a transfer device for a plate-like member for improving the reliability of transfer.

The dimensions. The flanges 22 and 23 may not be entirely made of a rubber material, but may be formed only on the outer peripheral surface, or conversely, the pulley 2 may be entirely made of a rubber material. Further, one or more grooves may be added to the outer peripheral surface of the flange 22. By the way, in each pulley 1 and 2,
If the belt to be wound is a toothed belt and the winding part is a toothed structure, slipping with the belt is prevented, and the take-in force, transport force, and feed output are further increased, and transport reliability is improved. it can.
