Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a hopper-type coin that is installed inside a slot machine, a money changer, a vending machine, etc., and is mainly used to dispense a required number of coins, medals, and other coins. Use the cheek dispensing device.

The present invention is an improvement of the known invention relating to the coin dispenser shown in FIG. 7.

This is related to U.S. Patent No. 3,942,544, and there is a hopper (a) that accommodates coins, a hopper (a) that picks up coins one by one, and a carry-out section (b).
An inclined rotary disk (C) to be transferred to the head yarn, and three ball bearing links that rotatably support this head yarn/one rotation disk (C) by engaging it at three points on its peripheral edge (d). Also, ゛ is Laura (
Below, ρ(e) (e) represents ball bearing ζ
(e) and between the tilted rotating disk (C) and the non-integral -va)
Therefore, it is equipped with a drive device (IJI) that transmits rotational force to this. Take this conventional example, (-fi

b) characterized in that the bending moment, thrust force, etc. acting on the ball bearing (e) are supported by the ball bearings (e), while the bending moment, etc. is not transmitted to the drive device; Ru.

A device that precedes this known invention? L had the following problems because it had a configuration in which the inclined rotary disk (c) was integrally attached to the output shaft of the drive device. The first problem is that a bending moment is exerted by the gravity of the many coins acting on the lower part of the tilted rotary disk (c), causing the output shaft to bend downward. The second problem is +'+iJ
Since the bending moment changes with the rotation of the tilted rotary disk (C), the bending moment repeatedly acts on the output shaft. The third problem is that when the tilted rotary disk (-) rotates while stirring the large number of coins in the hopper (a), a variable torsional moment acts directly on the output shaft due to the resistance of the coins. As a result of these problems, the above device cannot smoothly rotate the inclined rotary disk (C), leading to poor coin feeding and coin jams, and also causes the #4 inclined rotating disk (C) to rotate. It takes a large amount of driving force to do this, and it also lacks durability.

The above-mentioned known invention solves the drawbacks of the previous device in that the bending moment and torsional moment are 1iIkA moving device l.
The drive device +ffi and the amount of inclination +[
114 with a non-integral relationship with the disc (C), and #
, i'l east 1 rotating disk (c) is solved by supporting the 31-ball bearing (e) (e) (e).

However, even with this invention, there is a drawback that after long-term use, the tilted rotating disk (c) swings out significantly, leading to poor coin feeding and coin jamming. This is the bending moment acting on the tilted rotating disk (C) -! 'If the expected variable screw moment is exceeded, the ball bearing (e) (e) fe) will be worn out and the ball bearing (e) (e) (e) will rotate eccentrically with respect to its spindle. This causes the precession of the inclined rotating disk (C) to be exaggerated, causing vibrations in the IJ4 inclined rotating disk (C), and furthermore, this vibration causes the ball bearing (e
) (e) (e) This results in a vicious cycle in which the wear and tear of (e) becomes even more severe.

SUMMARY OF THE INVENTION An object of the present invention is to correct the drawbacks of the conventional example and provide a popper type coin dispensing device that can be used for a long period of time.

Another object of the present invention is to provide a hopper type coin dispensing device equipped with an inclined rotary inner plate support member that is lower in cost than the conventional example.

3) The inserted coin is delivered to a desired location.The present invention can be implemented in various ways in addition to those shown in the above embodiments. For example, four or more supporting parts 47j (5) (5) that rotatably support the inclined rotary disk (3) by engaging with one of four or more places on its peripheral edge (4) - - It can be made into a 41゛q configuration with one.

In addition, the bearing part 4, t (5) may be made of other types of fluororesin in addition to the fluororesin sliding bearing part 4 shown in the embodiment shown in -1- above. I can do it.

For example, +) iJ support member (5) is made of mica, talc, silica 11
The sliding bearing member may be formed from polytetrafluoroethylene mixed with aluminum or silicate powder such as glass.

Furthermore, as shown in FIG. 6, it is preferable to configure the mounting position of the support member (5) so that it can be adjusted in the direction of the centripetal force. In the direction shown in FIG. 6, (48) is the substrate (13).
The elongated hole (49 x 49) provided in is a lock nut.

The present invention is described in 1i! Because it has precepts, it has the following functions and effects.

First of all, since the tilted rotary disk (3) is rotated by the drive device (6) which is not integrally connected to the tilted rotary disk (3), the tilted rotary disk (3) is rotated by the drive device (6). Repeated bending moments and fluctuating torsional moments do not affect the drive device E: (6), and the tilting rotary shaft (3) can be rotated smoothly.

Second, the 11.11 oblique rotating disk (3) is
)'s 3t9: 3 that engages at or above the i position and supports rotatably
The supporting member (5) (5) of 111'l1 or more has an arcuate engagement (7) of approximately the same curvature as the peripheral edge (4a) of the inclined rotating disk (3), and is made of fluorine. Since it is made up of a sliding bearing member made of a sliding bearing made of resin, the tilting rotating disk (3) and the supporting member (5) (5) --
The Q friction coefficient between u4 is the smallest, and the tilted rotating disk (3)
The rotation is smoother than that of the known invention shown in No. 701. Therefore, the positive (Al
f71 operation can be expected, the coin force i can be smoothly fed out, and less power is consumed to rotate the inclined rotary disk (3).

Although the third action and effect are the most important, the drawbacks of the known invention shown in t1°', 71:'4 do not occur even after long-term use. Nanarara, sliding bearing (supporting member) made of fluororesin (5H5) --1 to 11! Because of its circular arc shape and 11 grooves (force and tilted rotating disk)
3) The friction between them is small, and the friction between them is also small. Therefore, even after long-term use, the 1111 oblique rotary disk (3) can be supported by the supporting members (5) (5) in the same state as when set, and the work of sending out the coin turtle can be carried out smoothly. I can do it. Regarding the known invention shown in FIG.
) (e) Or the rollers are easily worn out, which causes them to rotate eccentrically with respect to their spindles, which tends to have a negative effect on the rotation of the inclined rotating disk (c). In the present invention, since the support j, 1; material (5J(5) 4117) is formed by a sliding bearing made of fluororesin, there is no possibility of the above-mentioned drawback occurring.

Fourthly, the fluorine-based 'o'rJ)'M slide bearing (bearing part lit) (5) can be purchased at less than half the price of ball bearings, so manufacturing costs can be reduced. I can do it.

Fifth, a sliding bearing (supporting member) made of fluorine-based resin (5)
does not require lubrication, so dirt, etc.
) and the peripheral edge (4) of the tilted rotary disk (3), which is advantageous in maintaining normal rotation of the tilted rotary disk (3).

f, 'J, As in the embodiments described in l, the sliding bearing (support member) (5) is attached to its support shaft (or support bolt) (20).
(23) is advantageously supported so as to be swingable, since it is possible to absorb dimensional errors caused by distortion of the tilted rotary disk (3). Further, as shown in Fig. 6, the mounting position of the support member (5) can be adjusted in the centripetal direction by 11.? When it is done,
The arcuate retaining groove (preferable because it can deal with force loss).
