Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coin sorting device, and more particularly, to a coin sorting device of the type that includes a check member, commonly referred to as a cradle, which has the function of nicking the diameter and weight percent of an input coin.

Generally, the cradle of such a coin sorting device has two engaging pieces 2 and 3 spaced back and forth at a predetermined interval corresponding to the diameter of the coins to be sorted, as shown by 1 in FIG. two parallel spaced side plates 5, 6 defining the sorting passage 4;
is pivotally connected to a pivot pin 7 provided on one side of the
The above-mentioned two engaging pieces 2 and 3 are projected into the passage 4 through the arcuate windows 8 and 9 of the side plate 5, respectively, and have a balance weight 10 to insert a defective coin S having a smaller diameter than the normal diameter. When the small-diameter defective coin S is held in a predetermined balance position where it can pass between the engaging pieces 2 and 3 downward as shown by arrow A, the inserted coin R of the normal diameter is held in the cradle. When engaging both engaging pieces 2 and 3 and riding on the cradle, the cradle 1 loses its balance and rotates as shown by arrow B, causing the coin R to rotate into the passageway 4 and move in the direction of arrow C. It is configured to advance as shown.

The above-mentioned cradle is a drop-type coin sorter in which coins are inserted from the coin input slot located almost directly above the cradle 1 as shown by the arrow in Figure 2, and fall almost vertically between the two holding pieces 2 and 3. Although the device can perform highly accurate diameter and weight percent nicking functions, as shown in FIG.
4, and one of the side plates 5 and 6 is integrally fixed to the back side of the top plate 11. When the cradle is attached to a front-type coin sorting device, the coin slot 12 is located at an upper side position of the cradle. Because of this, the coin path from the coin slot to the cradle varies depending on the pushing force when inserting the coin, as shown for example at A, B, and C in Figure 3, and the coin engages with the cradle. Because the kinetic energy of the actual coin is different, sometimes even a small-diameter defective coin S engages with the front engagement piece 2 and gets on the cradle and rotates, just like a regular-diameter coin. There is a drawback that it passes through.

In order to eliminate the above-mentioned drawbacks, the applicant has pivoted the engaging lever 15 to the side plate 6 by means of a pin 16, as shown in FIG. A piece 17 is provided, and this interlocking finger piece 17 is attached to the window 18 of the side plate 6.
The balance weight portion 19 is made to protrude into the passage 4 through the
is provided on the engagement lever 15 to urge the engagement portion 20 of the balance weight portion 19 to engage with the stopper 21, thereby moving the engagement finger piece 17 at the upper end of the engagement lever 15 into the passageway at a position almost directly above the front side engagement piece 2. 4, so that a coin inserted from the coin slot 12 hits the engaging finger piece 17 before engaging the front engaging piece 2 of the cradle 1,
Even if the pushing force of the coin varies, the kinetic energy due to the pushing force is absorbed by rotating the engaging lever 15 by an amount corresponding to the magnitude of the kinetic energy of the coin, thereby directing the coin toward the cradle 1. It was configured to fall almost vertically.

However, as a result of testing with the above-mentioned engaging lever 15 installed, it was found that on rare occasions, approximately once for every hundreds of small-diameter coin insertion tests, small-diameter coins rotated through the cradle and passed forward. It turned out that there may be cases.

Therefore, in order to completely prevent such small-diameter coins from passing through, as a result of various considerations and experiments, it was found that the small-diameter coins S inserted from the coin input port 12 located at the upper side position of the cradle do not pass through the latch finger at the upper end of the latch lever 15. When engaging the piece 17, the small-diameter coin S rotating in the forward direction as shown by arrow A pushes the engaging lever 15 forward as shown by arrow B via the engaging finger piece 17 and engages the front engaging claw. 2, and when the small diameter coin S falls vertically toward the cradle 1 in this state, it engages the front retaining piece 2 and rotates the cradle 1, thereby causing both the engaging pieces 2, 3 to rotate. It has been confirmed that there are cases where the coin advances directly to the coin sorting passageway 4 without falling through the gap.

The above-mentioned passage of small diameter coins becomes a problem when the regular diameter coin R is, for example, a 100 yen coin and the small diameter coin S is a 50 yen coin. This is because the 50 yen coin and the 100 yen coin are made of the same material. This is because it cannot be sorted out later by checking the material quality.

Therefore, the purpose of the present invention is to rotate the cradle 1 and pass the 50 yen coin, which is a small diameter coin, to the coin sorting passage 4 without falling through between the engaging pieces 2 and 3 of the cradle 1. The aim is to provide a means to completely prevent this.

The present invention was developed by paying attention to the fact that the 50F3 coin has serrations on its outer periphery, and the above-mentioned latching finger piece 17 at the free end of the latching lever 15 is provided with an engaging pawl that can engage with the serrations on the outer periphery of the coin. The coin reverses its own rotation by engaging with the notches on the outer circumference of the coin, that is, as mentioned above, the coin that is rotating in the forward direction is reversed in the opposite direction. This prevents the small-diameter 50 yen coin from engaging with the front engagement piece of the cradle, and even if it does engage, the engagement position is misaligned and the cradle cannot be completely rotated. This completely prevents 50 yen coins from being fed into the coin sorting passage.

FIG. 5 is a view showing one embodiment of the present invention, and in the illustrated example, a thin plate piece 22 capable of engaging with the coin outer circumferential serrations is riveted to the above-mentioned engaging lever 15, and the edge of the thin plate piece 22 is protrudes from the engaging finger piece 17 and attaches the engaging claw 2 to the free end of the engaging lever 15.
There are 3.

In the drawings, reference numeral 25 denotes an elastic connecting piece that hinges the upper edge of the movable side plate 5 to the fixed side plate 6 fixed to the top plate 11, and 26 denotes an elastic connecting piece that is rotated by the cradle 1 and transferred into the coin sorting passage 4. A magnetic device 27 applies a magnetic braking action to moving coins to check the material, and a magnetic device 27 is located at the branch point between the passage to the regular coin outlet 28 and the passage to the defective coin return chute 29. Check piece 31
a pendulum lever whose upper end is pivotally connected to the side plate 6 by a pin 32 so that the pendulum lever is swingably suspended; 33 is a regular coin detection microswitch provided at the coin outlet 28; 34
is the switch lever, 35 and 36 are the return lever 1
3 and a passive plate fixed to the movable side plate 5, which are configured to cooperate with each other at a contact surface formed by an involute curve.

FIG. 6 shows the action of the engaging pawl 23 provided at the free end of the above-mentioned engaging lever 17, and shows that a 50 yen coin S, which is a small-diameter coin, inserted from the coin slot 12, as shown by arrow A in FIG. When hitting the engaging pawl 23 while rotating in the forward direction, the engaging pawl 23
When the coin S engages with the jagged groove on the outer circumference of the coin S, the rotation direction is reversed to the direction shown by arrow B in the opposite direction.

Due to this reversal in the opposite advancing direction B, the force to push the engaging lever 17 also weakens, and the coin S continues its course into the cradle 1.
It falls between the two locking pieces 2 and 3.

As described above, according to the present invention, when the coin pushed into the coin slot located at the upper side of the cradle is a coin with a diameter smaller than the normal diameter and has a serration on the outer periphery, the small-diameter serration coin is The horizontal momentum caused by the pushing force engages with the front retaining piece of the cradle to reliably prevent the cradle from rotating and moving forward into the coin sorting passage. It is possible to completely prevent unauthorized use of the 50 yen coin when it is a used coin.

In carrying out the present invention, the present invention is not limited to the embodiment shown in FIG. 5, and for example, an engaging claw capable of engaging with a notch on the outer circumference of a coin may be directly formed on the engaging finger piece 17 at the free end of the engaging lever 15. Of course, the lever 15 may be suspended from above, and the lower free end thereof may be positioned directly above the front retaining piece of the cradle.
