A pulley 3 is rotatably provided on the top via a bearing 2, and this pulley 3 has a pair of first pulley pieces 3a as an upper flange and a lower flange provided at a distance from each other. It is composed of a second pulley piece 3b.

A belt guide recess 4a for suspending a belt 5 made of rubber or the like and having an O-shaped cross section is formed in the gap between the first pulley piece 3a and the second pulley piece 3b. for,
A coin guide recess 4 for guiding coins is formed located on the second pulley piece 3b side and communicating with the second pulley piece 3b. The second pulley piece 3b is held in the recess 1a of the substrate 1, and the upper surface 3c of the second pulley piece 3b
and the upper surface 1b of the substrate 1 are formed so as to be substantially on the same plane, so that the coin 6 is easily guided.

Further, on the upper surface 1b side of the substrate 1 and on the outer peripheral side of the pulley 3, there is provided a first coin guide member that is generally L-shaped in its entirety and that corrects the course of the coin 6 and prevents it from flying outward. 7 is provided. Further, a second coin guide member 8 is provided on the upper surface 1b side of the substrate 1 and on the coin outlet side of the pulley 3 for guiding the course of the coin 6 whose trajectory has been corrected to the downstream side.

The configuration shown in FIGS. 2 and 3 described above shows the coin bending conveyance unit 9 consisting of the pulley 3, belt 5, etc., and the configuration in which this coin bending conveyance unit 9 is attached to the coin processing machine 10 is as follows. As shown in FIG.

That is, in FIG. 1, the coin bending and conveying section 9 is disposed at a corner 1c of the base plate 1, and a holding member 11 for bearing and holding the upper part of the pulley 3 is attached by a mounting means (not shown). It is fixedly mounted on the substrate 1. This holding member 11
A guide pulley 12 is rotatably provided on the upper part of the guide pulley 12, and the pulley 3 and the guide pulley 12 are integrally connected to each other by a shaft (not shown).

On the coin entrance section 13 side of the coin bending conveyance section 9, there is provided a belt conveyor mechanism (not shown) for guiding the coins 6 from the coin supply section 14 provided on the base plate 1 while being held in the passage. A coin transport section 15 is provided, and this coin transport section 15
The coins 6 conveyed by are guided to the coin entrance section 13 of the coin bending conveyance section 9. Further, a coin guide conveyance section 17 is provided on the coin outlet section 16 side of the coin bending conveyance section 9 for storing the direction-changed coins 6 in a downstream storage section or coin sorting section (not shown). The belt 5 is coaxially suspended from a guide pulley 18 constituting the coin guide conveyance section 17 . Therefore, the pulley 3
Both the guide pulley 18 and the guide pulley 18 are configured to rotate in synchronization.

Next, a case will be described in which the coin transport mechanism is operated based on the above configuration.

The coins 6 supplied from the coin supply section 14 are
The coins are guided through the coin transport section 15 to the coin entrance section 13 of the coin bending transport section 9 . This coin entrance section 13
The coin 6 guided by is inserted between the belt 5 and the base plate 1, and at this time, the belt 5 is driven by a driving means (not shown), and the pulley 3 is synchronously driven. Due to the rotation,
As the movement of the coin 6 further progresses, it is guided and placed on the second pulley piece 3b of the pulley 3, further advances to the coin guide recess 4, and is held between the belt 5 and the second pulley piece 3b. As the pulley 3 rotates in the direction of arrow A, it is transported while being placed on the second pulley piece 3b, and changes direction by about 90 degrees from the direction of arrow B to the direction of arrow C. will be carried out. During this bending and conveyance, the coin 6 tends to fly outward due to its centrifugal force, but the side wall 7a of the first coin guide member 7 prevents the coin from jumping out.

On the other hand, when the coin 6 reaches the coin outlet section 16 and is released from the grip between the belt 5 and the second pulley piece 3b, a centripetal force acts that causes the center of the coin 6 to deviate inward from the belt 5. A second coin guide member 8 disposed near the coin outlet portion 16 guides the coin 6 so that it is accurately guided along the changed course. Thereafter, the coin 6 is fed into a coin storage section, a coin sorting section, etc. (not shown) by the coin guiding and conveying section 17.

Although the case where the coin guide member 7 is constructed separately on the substrate 1 has been described, the same effect can be obtained when the coin guide member 7 is constructed integrally with the substrate 1.

Further, although the case where the pulley 3 is housed in the concave portion 1a of the substrate 1 has been described, the same effect can be obtained even when the concave portion 1a is not formed and a tapered portion is formed on the substrate 1 to guide the coin. It is something that can be done.

g. Effects of the invention Since the coin conveyance mechanism according to the invention has the above-described structure and operation, the coin is placed on the pulley piece and is held between the O-shaped belt and the pulley piece. The coins can be conveyed integrally and the course can be changed in a state where the coins are conveyed, and the coins can be reliably conveyed without causing conveyance errors or coin jams in the middle of the conveyance path.
