Description

[Detailed Description of the Invention] The present invention relates to an improvement in adjusting the gap between the coin sending rotary body of a coin processing machine and the coin passage board.

A coin processing machine arranges coins supplied on a rotating disk in one line and guides them onto a coin passage, and sends the coins along this passage into a packaging section or a collecting cylinder using a delivery belt. While the coin is running, processing such as sorting and counting of denominations is performed.

Conventionally, however, the gap between the delivery rotating body for rotating the delivery belt and the passage board in the coin passage was fixed.

There is only a slight difference in the thickness of various domestic coins (0.25 mm).
) Since we were targeting only coins with no L size, the gap between the sending rotary body and the passage board, which was installed at the position where coins were introduced one by one from the rotating disk and counted by the star gear, was fixed. However, when dealing with foreign coins where the difference in the thickness of the coins is significant (approximately 2.0 mm), the gap is adjusted to the thinnest coin, so in the case of thick coins. In some cases, the coins were pressed too tightly against the board, which caused problems with the coin delivery and caused the delivery to be interrupted, or the coins got caught in a part of the sorting opening, significantly impeding work efficiency.

That is, as shown in FIG. 3, in the case of the conventional fixed delivery rotating body 6, thick coins 1 are
5' is strongly pressed at the tip in the sending direction, and the coin 15
'' passes through the coin passage 26 in an unstable posture with its tip slightly falling into the sorting hole 27, and when it reaches the passage board 22, the tip gets caught in the corner of the passage board 22, obstructing the smooth passage of coins.

In order to eliminate these drawbacks, the present invention has a simple structure that reliably corresponds to thick and thin denominations, and by adjusting the gap between the delivery rotor and the board, it maintains the optimum coin delivery condition and improves work efficiency. It measures the improvement of

Next, a description will be given based on the embodiment shown in the drawings.A shaft 3K passing through a support 2 fixed to the fuselage 1 is rotatably mounted on one side of the left side of the holder 4 in FIG. A delivery rotary body 6 is fixedly provided at one end of a rotatable main shaft 5 passing through a holder 4 in parallel with the shaft 3, and a drive pulley 25 is provided at the other end.
The belt 8 is configured to drive the rotary transfer body 6 by attaching the belt 8.

In addition, a pulley arm 10 is loosely fitted into the boss portion of the bearing 9 of the main shaft 5 provided on the holder 4, and a torsion spring 11 is installed between the two, so that the pulley arm 10 is constantly rotated downward by the elasticity of the torsion spring 11. A shaft 12 fixedly provided at the tip of the arm 10
A rotatable driven pulley 6' is attached to the belt, and a delivery belt 13 is stretched between the delivery belt 13 and the delivery rotation body 6. The coin 15 is moved inside the coin passage 26 to the left in FIG.

-i As a known device, a width setting cam 17 of the coin passage 26 and a gap adjustment cam 18 corresponding to the thickness of the coin can be mounted on the denomination selection knob shaft 16 by fixing them with a half-moon key with their mounting positions related to each other. be.

Therefore, when the knob shaft 16 is rotated by operating a denomination selection knob (not shown), the denomination setting cam 17 and the clearance adjustment cam 18 are also rotated, and a position corresponding to the denomination selected by the knob is selected. At the same time, a rotatable roller 21 is provided on a roller shaft 20 fixedly provided on the other side of the holding body 4 with respect to the negative side, that is, on the driven pulley 6' side of the main shaft 5, and this roller 21 is connected to the gap adjusting cam 18. By pressing against the cam surface of the holding body 4, the height position of the holding body 4 changes around the shaft 3, and the position of the delivery rotary body 6 also changes.

This change in the position of the delivery rotary body 6 changes around the shaft 3, which is parallel to the main shaft 5 that supports the delivery rotary body 6 and opposite to the side where the driven pulley 6' is located. It is located on the side.

Therefore, the plane including the rotation locus of the rotating body 6 through the holder 4 and the main shaft 5 about the shaft 3 changes its position above the coin passage 26 and always in the passage direction perpendicular to the plane of this passage. .

That is, the delivery belt 13 stretched around the delivery rotating body 6 has a flat contact surface parallel to the surface of the coin 15 on the coin passage 26, and the entire width of the contact surface is in contact with the coin 15 to ensure delivery of the coin. However, in the case of the present invention, even if the delivery rotating body 6 changes in height as described above, the contact surface and the surface of the coin are always in parallel motion, so the delivery belt can move regardless of the thickness of the coin. The entire width of the coin 13 contacts the coin 15 uniformly to ensure delivery.

However, if the holder 4 is pivoted at a position where the shaft 3 is perpendicular to the main shaft 5, for example at the drive pulley 25, and the delivery rotor 6 is adjusted in height depending on the thickness of the coin,
The contact surface of the delivery belt 13 and the surface of the coin do not move in parallel, and depending on the thickness of the coin, the one side of the delivery belt 13 that falls in the width direction is strongly pressed, and the other side is weakly pressed. There is a drawback that the coins are delivered unevenly.

Therefore, the gap between the passage board 22 and the delivery belt 13 is
It is possible to preferably regulate the gap to the optimum gap for the denomination.

In order to press the roller 21 and the gap adjustment cam 18, the roller 21 is held by a locking pin 23 provided on two parts of the holder 4, and is held by a spring 24 stretched between the roller 21 and the body 1. It is made to come into pressure contact with the surface of the cam 18.

Since the present invention is constructed as described above, the structure is simple, and the optimum gap is reliably set for both thick and thin coins, and the coins are pressed into good contact with the delivery belt, so that the coins can be processed smoothly. This significantly improves work efficiency.
