Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a coin center hole checking device in a coin sorting device equipped with a cradle for checking the diameter and weight of coins, etc.

(Prior Art) Conventionally, as a coin center hole checking device for a coin sorting device equipped with a cradle, there is known a device as described in, for example, Japanese Utility Model Publication No. 35-11004.

In the coin center hole checking device described in the above-mentioned publication, the center hole check lever is pivotably pivoted to rotate in a plane perpendicular to the rotating surface of the cradle, and the coin hooking end of the check lever is The coin retaining end of the check lever is configured to protrude from the outside of the coin passage into the space between the arms of the cradle through a hole in the side plate of the coin passage, and when the cradle is at a balanced and resting position, the coin hooking end of the check lever is attached to the cradle. The coin hooking end is engaged with the upper edge of the arm and held without protruding into the coin passage through the opening hole of the side plate, and the inserted coin is engaged with both engaging pieces of the cradle and placed in the cradle. When the cradle rotates due to a coin being placed on it, the arm of the cradle that engages and holds the coin latching end descends, causing the coin latching end to disengage from the cradle arm and cause the arm to hang. When the coin is no longer held and the coin latching end always protrudes at a fixed position into the coin passage through the opening hole in the side plate, and the coin resting on the cradle has a center hole,
The coin hanging end part enters into the coin center hole and engages with the upper end of the inner peripheral edge of the center hole of the coin, so that the pseudo coin with the center hole is suspended and stopped in the cradle by the coin hanging end part. A mechanism for removing pseudo coins with a center hole is described.

(Problems to be Solved by the Invention) However, in the coin center hole check lever which is pivotally mounted so as to be swingable, the coin center hole check lever extends almost perpendicularly from the pivot portion toward the opening hole, Since the coin hanging end of the end protrudes into the coin passage at a certain position, the coin hanging end engages with the upper end of the inner peripheral edge of the center hole of the coin placed on the cradle. When the coin is stopped in the coin passage, the coin is suspended only by the coin hooking end of the swingable coin center hole check lever, and is suspended in an unstable state where it floats up from the cradle. . Therefore, if an impact is applied from the outside in such an unstable holding position, the inner peripheral edge of the coin center hole and the coin latching end will disengage, and the cradle will rotate again due to the coin's own weight. A problem arises in that coins with a center hole are accepted as good coins.

An object of the present invention is to solve the problem of the conventional device, which is caused by the fact that a coin with a center hole, which is hooked to the coin hooking end at the tip of the center hole check lever, easily comes off from the coin hooking end, as described above. The coin hooking end at the tip of the center hole check lever is fully inserted into the center hole of the coin with a center hole, and when the center hole check lever is tilted to a near horizontal position, the coin hooking end will not hold the coin. It is an object of the present invention to provide a coin center hole checking device suitably constructed to engage a center hole and hold a center hole coin.

(Means for Solving the Problems) According to the present invention, as shown in the drawings, a coin passage 5 is formed between the two side plates 1 and 2, and the coin passage 5 is formed at intervals corresponding to the diameters of prescribed coins to be sorted. A cradle 6 having two engaging pieces 8 and 9 protruding apart from each other.
is rotatably pivoted to one side plate 1, and the engaging pieces are projected into the coin passage 5 through holes 10 and 11 formed in the side plate 1, and the inside of the coin passage is directed between the engaging pieces. When the input coin falling substantially vertically engages with both of the engaging pieces and rides on the cradle, the cradle rotates to the coin sending side and sends the coins on the cradle to the next coin sorting passage. In the constructed coin sorting device, the coin center hole check lever 20 is connected to the stationary support portion 13d on the side plate 1 by a pivot portion 20a that is perpendicular to the lever body at one end of the coin center hole check lever 20. The central hole of the coin, which is mounted on the cradle 6 and engaged with both engaging pieces 8 and 9 of the cradle 6, moves as the cradle rotates. The side plate 1 is provided with an opening hole 21 that opens in a corresponding area, and the coin center hole check lever 20 is inclined upwardly from the pivot portion 20a toward the opening hole 21 and extends. A support part 20c provided at the middle part of the cradle 6 is supported on the support surface 6a on the coin sending arm of the cradle 6, and when the cradle is not in operation, the coin hooking end part 20b at the extended end of the coin center hole check lever 20 is It is configured to be located in the opening hole 21, so that as the cradle rotates with the support portion 20c being engaged and held by the support surface 6a while the cradle is being rotated by a coin placed on the cradle, The coin latching end 20b enters into the center hole of the coin in the coin passage 5 from the opening hole 21, and the coin latching end 20b cradle the coin with the check lever 20 tilted to a near horizontal position. It is characterized by being held at the top.

(Function) According to the present invention, when the cradle 6 is rotated by a coin having the center hole and the coin hooking end portion 20b protrudes into the coin passage 5 and engages with the coin center hole, the coin center hole check lever is opened. Since the check lever support portion 20c is held in a stable position by being engaged with the support surface 6a of the cradle 6 when the entire check lever 20 is in a substantially horizontal position, the check lever 20 is not moved greatly by an external impact. Therefore, the coin hooking end portion 20b and the hardened center hole will not come out of engagement.

Embodiment FIGS. 1 through 6 illustrate the structure and operation of a coin center hole checking device according to an embodiment of the present invention.

In the figure, 6 is a cradle rotatably supported on a cradle pivot pin 7 implanted in the side plate 1.
This cradle 6 has two engaging pieces 8 and 9 that project forward and backward at a predetermined interval corresponding to the diameter of the prescribed coins to be sorted, and these engaging pieces 8 and 9 are attached to the side plate. An arcuate groove 10 formed in 1
The cradle 6 is moved by the balance weight 12 to a position where both the engaging pieces 8 and 9 can engage an inserted coin that is projected into the coin passage 5 through the coin passage 5 and 11 and dropped substantially vertically into the coin passage 5. When the inserted coin has a specified diameter and a specified weight, the coin engages with both engaging pieces 8 and 9 and rides on the cradle 6, and the cradle 6 is placed under the weight of the coin. As a result, the balance weight 12 loses its balance and rotates around the pivot pin 7 toward the coin delivery side, so that the coins on the cradle 6 are rolled and delivered to the next coin sorting passage (not shown). There is. Reference numeral 13 denotes a cradle support arm which is always placed in the illustrated position under a spring load.The upper end 1 of the cradle support arm 13 is attached to a pair of pivot parts 14, 14 protruding from the side plate by a pivot pin 15.
3a is pivotally mounted so that its lower end 13b is located on the cradle pivot pin 7, a cradle restraining cap 16 is provided on the lower end 13b of this cradle support arm 13, and this cap 16 is attached to the cradle pivot pin 7. Fit into the protruding tip and cradle 6
is constructed so that it does not fall off the pivot pin.

According to the present invention, as described above, a pair of upper and lower projecting ears 17 and 18 are provided protruding from the lower end support portion 13d of the support arm 13 that is always fixed to the side plate 1, and a pivot hole 19 is provided between these projecting ears. The coin center hole check lever 20 is bent at right angles to the lever body of the coin center hole check lever 20 and the extended pivot portion 20a is inserted into the pivot hole 19, whereby the coin center hole check lever 20 is inserted into the pivot portion 20a
The cradle 6 is pivotally mounted to be pivotable about the horizontal axis of the cradle 6 in a plane perpendicular to the rotation plane of the cradle 6. The coin center hole check lever 2 has the pivot portion 20a pivotally attached to the pivot hole 19 in this manner.
0 extends obliquely upward from the pivot portion 20a at right angles toward the side plate 1, and the coin hooking end 20b of the check lever 20 is positioned within the opening hole 21 provided in the side plate 1. In the illustrated example, the center hole B of the coin A placed on the cradle 6 is moved by the rotation of the cradle 8 by appropriately selecting the position of the opening hole 21 and engaging both the engaging pieces 8 and 9 of the cradle 6. The opening hole 21 is positioned within a moving range C (see FIG. 5).

Further, the coin center hole check lever 20 is provided with a bending support portion 20c at an intermediate position between the pivot portion 20a and the coin hooking end portion 20b, and this bending support portion 20c is supported by the upper edge of the coin delivery side arm of the cradle 6. Face 6
a, thereby supporting the cradle 6
When the coin-dispensing arm rotates toward the coin dispensing side, as the support surface 6a on the coin dispensing arm descends, the bending support portion 20c, which is engaged and supported on the coin dispensing arm, also descends. The lever 20 rotates around the axis of the pivot portion 20a, and the coin hooking end 20b located in the opening hole 21 descends as shown by 20'b (see Figures 4 to 6). Therefore, as the cradle 6 rotates, the coin hooking end 20b is configured to protrude from the opening hole 21 into the coin passage 5. In addition,
End 20d of the check lever 20 on the pivot portion 20a side
By bending the check lever to the side opposite to the coin hooking end 20b, the check lever is prevented from shifting in the horizontal direction. Further, the tip 20e of the coin hooking end 20b is bent to form a rounded end so that sliding contact with the side surface of the coin without a center hole can be made smoothly.

The operation of the apparatus configured as described above will now be described.

If the inserted coin is a regular coin that does not have a center hole, the coin engages with both engaging pieces 8 and 9 of the cradle 6 and rides on the cradle 6, so that the cradle 6 is attached to the pivot pin. 7 in the coin feeding direction.

Along with this rotation, the position of the support surface 6a on the coin sending arm is lowered, and as a result, the coin hooking end 20b of the coin center hole check lever 20 is moved to the opening hole 2.
However, the rounded tip 20e comes into contact with the side surface of the coin on the cradle 6, thereby preventing the coin hooking end 20b from entering the coin passage 5.

Therefore, regular coins that do not have a center hole are delivered to the next coin sorting passage by rotation of the cradle 6 toward the coin delivery side.

Next, when the inserted coin A has a center hole B, the cradle 6 on which the coin A is placed rotates in the coin dispensing direction in the same way as in the case of regular coins, and with this rotation, the coin dispensing side The position of the bearing surface 6a on the arm is lowered.

As a result, unlike the above-mentioned case of regular coins, the coin hooking end 20b of the coin center hole check lever 20 is opened from the opening hole 21 to the coin A on the cradle 6 in the coin passage 5, as shown in FIG. The coin hooking end 20b engages with the coin center hole B while the check lever 20 is tilted to a substantially horizontal position.

Therefore, even if the cradle 6 rotates toward the coin delivery side, the coin A having the center hole B cannot be held at the coin hooking end 2.
It is retained on the cradle 6 by the engagement between the center hole B and the center hole B.

Coin A held on cradle 6 like this
As is conventionally known, when the side plate 1 is opened by operating the return lever, the cradle 6 is opened.
When it loses engagement with the engaging pieces 8 and 9, it falls and is returned.

(Effects of the Invention) According to the present invention, when the coin retaining end of the check lever is engaged with the inner peripheral edge of the coin center hole and the coin is retained on the cradle, an external shock or the like is applied. Even if something happens, the coin hooking end part will not come off the center hole of the coin, and the coin with the center hole can be reliably prevented from being accepted as a good coin.
