Description

[Detailed explanation of the idea] The present invention relates to an accumulative coin mechanism.

Conventionally, storage type coin mechanisms have complicated structures, and those using hammer mechanisms have the possibility of the coins being stored falling off due to the weight of the storage coins and the impact of the hammer. It was necessary to set a severe spring pressure in the sorting lever mechanism that flicks out fraudulent coins.

The object of the present invention is to provide an accumulating coin mechanism which is simple in structure and reliable in operation, while eliminating the above-mentioned drawbacks.

Hereinafter, the present invention will be explained based on the illustrated embodiments.

As shown in FIG. 1, the base plate 1 and the back plate 3 on which the coin passage 2 is formed are overlapped and are substantially integrally formed.

A drive shaft 4 protrudes above the substrate 1 via a motor and a speed reduction mechanism (not shown) provided on the back plate 3.
A cam 5 and a pawl lever 6 are coaxially fixed and rotated in the direction of arrow a.

The board 1 has a support shaft 7. 8. 9 is fixedly mounted, and a cross-shaped switch lever 10 is rotatably mounted on the support shaft 7.

The tip of the first arm 11 of the switch lever 10 rises up to form a retaining portion 11a.

The tip of the second arm 12 also rises to form the retaining part 12 in the same way as above.
a is formed.

Further, the third arm 13 protrudes in the opposite direction to the first arm 11, and its tip rises up to form an engaging end 13a in the same manner as described above.The fourth arm 14 is connected to the second arm 12. The switch lever 10 protrudes in the opposite direction and is heavier than the second arm 12, and is given the habit of rotating in the direction of the arrow about the support shaft 7.

A holding lever 15 is attached to the support shaft 7, and a holding lever 15 is attached to the switch lever 1.
0 and is rotatably provided.

The holding lever 15 is formed in a Y-shape, and the tip of the first arm 16 is formed in a hook shape and serves as an abutment 16a.
The second arm 17 is in contact with the second arm 12 of the switch lever 10 .

A movable contact 21 is fixed to the tip of the third arm 18 via an insulator 19 and a leaf spring 20.

The holding lever 15 is moved by an arrow C by a spring (not shown).
A rotational behavior is given in the direction, that is, the direction in which the movable contact 21 is opened.

A fixed contact 2 is connected to the substrate 1 via an insulator 22 and a leaf spring 23.
4 is fixed and is provided opposite to the movable contact 21.

An actuator 25 is rotatably supported on a support shaft 9 fixed to the substrate 1, and one end of the actuator 25 serves as a detection end 25a and projects into the coin passage 2.

The other end is formed to have a larger weight than the detection end 25H, giving the actuator 25 the ability to rotate in the direction of the arrow d, and is also formed with a locking portion 25b, which allows the switch lever 10 to rotate. It is adapted to lock the engaging portion 11a.

A stop lever 26 having three arms is rotatably supported on a support shaft 8 fixed to the substrate 1.

The tip of the first arm 27 is formed into a hook shape, and the contact end 27 a
and is opposed to the cam 5.

The tip of the second arm 28 becomes a retaining portion 28a formed in the shape of a "he" and becomes the first arm 11 of the switch lever 10.
It is engaged with the engaging portion 11a of.

Further, the tip of the third arm 29 is bent and positioned in a recess 32 provided along the periphery of the coin passage 2 rather than a window 30 protruding from the base plate 1.

The stop lever 26 is moved in the direction of arrow e by a spring (not shown).
The rotational behavior of the direction is given.

Since the embodiment of the present invention is configured as described above, when a specific coin C1 is first inserted into the coin passage 2 from the input port 31, it falls along the coin passage 2 as shown in FIG. and is ejected from the aircraft.

At that time, the coin C1 is detected at the detection end 25 of the actuator 25.
At step a, the actuator 25 is rotated about the support shaft 9 against the rotational habit.

Due to the above rotation, the locking portion 25 of the actuator 25
The engagement portion 11a of the first arm 11 of the switch lever 10, which had been engaged with the switch lever 10b, is disengaged, and the switch lever 10
follows its rotational behavior and rotates in the direction indicated by the arrow.

Due to the above rotation, the engaging end 12a of the second arm 12 of the switch lever 10 rotates the second arm 17 of the holding lever 15 in the direction opposite to the arrow C against its rotational behavior.

By rotating the holding lever 15, the movable contact 21 fixed to the tip of the third arm 18 and the fixed contact 24 fixed to the substrate 1 are closed, and a motor (not shown) is started.

The rotation of the actuator 25 is also controlled by the stop lever 2.
6, the stop lever 25 is rotated along the engaging portion 28a formed on the second arm 28 in the direction opposite to the arrow e against its rotational tendency.

When the stop lever 25 is rotated, the blocking end 29a formed at the tip of the third arm 29 projects into the coin passage 2 from the recess 32 provided at the periphery of the coin passage 2, thereby blocking the coin following the first coin C0. C2 and C3 are prevented from passing and are stacked and accumulated in the coin passage 2.

By closing the contacts 21, 24, the motor (not shown) rotates, and the cam 5 and the pawl lever 6 rotate in the direction of the rotation arrow a as shown in FIG. 4 via the speed reducer and drive shaft 4 (not shown).

Due to the rotation of the cam 5, the holding lever 15 is moved to the contact point 21.
．． 24 is kept open, and the blocking end 29a of the stop lever 26 is projected into the coin passage 2 to keep the coins C2 and C3 blocked.

When the cam 5 and pawl lever 6 further rotate from this state,
Since the engaging end 13a formed at the tip of the third arm 13 of the switch lever 10 is located within the rotation locus of the claw lever 6, the switch lever 10 is prevented from rotating by the claw lever 6. Turn the first arm 11 in the direction of the arrow.
the engaging portion 11a of the actuator 25 and the locking portion 25 of the actuator 25
The actuator 2, which had been pressed down by the coin C1 (see Figure 3), is engaged again with the coin C1 (see Figure 3).
The detection end 25a of No. 5 returns to its initial state again.

At this time, since the contact end 16a of the first arm 16 of the holding lever 15 is in contact with the circumferential surface of the cam 5, the movable contact 21 is not released from the fixed contact 24.

When the cam 5 further rotates from the above state, as shown in FIG.
a falls into the recess on the circumferential surface of the cam 5 and moves significantly, so that the blocking end 29a of the third arm 29 is pushed from inside the coin passage 2.
It is drawn into a recess 32 formed on its circumferential surface.

Therefore, the coin C2 falls. Since the distance between the blocking end 29a and the detecting end 25a is approximately the length of one coin, the coin C that falls from the blocking end 29a is
2 rotates the actuator 25 again as shown in FIG. 7, and simultaneously the stop lever 26 rotates and the blocking end 29 a
prevents the coin C3 from falling after protruding into the coin passage 2.

The operations shown in Figures 3 to 7 above are repeated until the accumulated coins run out, and after the cam 5 has made one revolution, it returns to the initial state shown in Figure 1, and the contacts 21 and 24 are opened and connected to the motor and load. energization is stopped.

As an alternative embodiment to the above embodiment, the relationship between the stop lever and the cam can be operated in the same manner using another lever as a medium.

Furthermore, the stop lever and the switch lever do not need to be engaged; instead, the stop lever may be directly linked to the actuator.

As described above, by using the storage type coin mechanism of the present invention, the structure is simpler and the operation is more reliable than the conventional one, and the current capacity of the contacts can also be increased.

Furthermore, by making the coin passage longer, the amount of storage can be easily increased.
