Description

[Detailed explanation of the idea] The present invention relates to an improvement of a manual vending machine.

Generally, this type of vending machine is constructed so that when a predetermined amount of money is held in the coin holding mechanism, the product can be ejected by rotating an operating knob provided outside the machine.

However, even if a predetermined amount of money is not held in the holding mechanism, depending on the coin insertion operation and the timing of the picking operation, the coin may be stopped and retained in the coin receiving opening of the holding mechanism, so that the coin may not be properly inserted. The conventional structure had a drawback in that it could be sold with one coin without the regular input of a predetermined amount in order to create the same condition as the final coin of the predetermined amount.

In view of the above points, it is an object of the present invention to provide a vending machine that can eliminate the above drawbacks.

An embodiment of the present invention will be described below in detail based on the drawings.

First, an operating knob 2 that can be rotated left and right is provided on the outside of the machine body 1 of the vending machine, and a horizontal shaft 3 is provided horizontally inside the machine body 1, and a cylindrical body 4 and the knob 2 are mounted on the horizontal shaft 3. A rotation transmission mechanism 6 connects the rotation shaft 5 connected to the rotation shaft 5 .

The transmission mechanism 6 includes a worm gear 7 provided at the end of the rotating shaft 5.
and a worm wheel 8 formed on the peripheral surface of the cylinder 4.
When the knob 2 is rotated in one direction, the cylinder body 4 is rotated in one direction via the transmission mechanism 6, and when the knob 2 is rotated in the other direction, the cylinder body 4 is rotated in the other direction.

A circular coin holding body 9 is fixed to the other end of the cylinder 4.

The holding body 9 is formed by overlapping three plates, and has coin receiving openings 10, 10 arranged vertically in pairs on the outer periphery, and holds coins inside. A lower end opening 12 of a hard coin drop chute 11 that drops from a coin sorting device (not shown) is exposed to the receiving opening 10.

On the other hand, at the end of the horizontal shaft 3, a circular ratchet plate 14 with ratchet teeth 13 carved in the horizontal direction and a 8-shaped cam plate 15 smaller than the ratchet plate 14 are integrally formed. The operating gear 16 is fixed.

The ratchet plate 14 and the coin holding body 9 have protrusions 17, 17 and receiving protrusions 18, 18 on the opposing surfaces thereof, respectively.
are provided and brought into contact with each other using springs not shown.

That is, if the coin holding body 9 rotates in the direction in which the receiving protrusion 18 presses the protruding piece 17 of the ratchet plate 14 (in the direction of the arrow in FIG. 3), the holding body 9 and the operating gear 16 are integrally formed. When the horizontal shaft 3 is rotated and the receiving projection piece 18 is in the direction away from the projection piece 17, the holding body 9 rotates independently and the operating gear 1
6 and the horizontal axis 3 are not rotated.

Therefore, when the horizontal shaft 3 rotates, the product delivery blade 3a fixed to the horizontal shaft 3 also rotates, making it possible to deliver the product.

There are two windows 1 at the top and bottom at positions facing the coin storage paths 9a, 9a communicating with the coin receiving opening 10.10 of the coin storage body 9.
9, 19, 20, and 20 respectively.

In this embodiment, the windows 19, 19 and 20 are arranged so that the coins closest to the receiving port 10, 10 of the plurality of coins stored in the storage channels 9a, 9a, that is, the last coin and the next previous coin, can be viewed.
, 20 respectively.

Then, through the windows 19 and 19, the coin storage paths 9a, 9
A first locking member 22, whose one end is pivotally supported in a manner that it can move forward and backward from the operating gear 16 side, and which is biased in the withdrawal direction by a spring 21, is fixed to the coin holding body 9, and the first locking member 22 is fixed to the coin holding body 9. The second end is pivoted at one end so that it can move forward and backward from the other side into the coin storage path 9a, 9a through the coin storage path 9a, and is biased in the entering direction by a leaf spring 23 and normally abuts against the coin storage body 9. Locking member 24
, 24 are provided.

Notches 25 and 25 are formed on the periphery of the ratchet plate 14 at positions corresponding to the receiving openings 10, 10 of the coin holding body 9.

Further, a plate spring 28 fixed to the wall body 27 is biased to a position where it can come into contact with the first locking member 22 so as to engage the one notch 25 in the waiting state for sales. A locking member 29 is rotatably supported.

However, the bent portion 26 at one end of the locking member 29 abuts against the wall 27 and its rotation is restricted.

The leaf spring 28 is the spring 21 of the first locking member 22.
It has a stronger urging force than the urging force of .

Reference numeral 30 denotes a stopper, which comes into contact and locks when the first locking member 22 is pushed away by the locking member 29 when the knob 2 is rotated even though no coins are stored inside the coin storage body 9. This is to prevent the coin holder 9 from rotating any further.

The cam plate 15 urges the horizontal shaft 3 to rotate, and presses against a roller 32 at the tip of a pressing frame 31 whose one end is pivotally supported, so that when the horizontal shaft 3 rotates, the roller 32 moves it to the normal position. This makes it easier to stop.

Reference numeral 33 designates a coin holding member, whose end is biased toward the front of the body 1 by a coil spring 34, and a fixing pin 36 is inserted into a guide hole 35 formed at the other end.

Therefore, when the coin holding body 9 rotates in the direction of the arrow in FIG.
9b comes into contact with the hook portion 33a of the clamping member 33, and the clamping member 33 slides on the coin dropping chute 11 against the coil spring 34.

In addition, in FIG. 2, the right side of the clamping member 33 is composed of two plates, and in the standby state, the dropping chute 11 is opened and coins can fall, but the coins cannot be dropped into the dropping chute 11. When an attempt is made to rotate the coin holding body 9 when there is a coin, the coin is held by the coin holding member 33 without falling, and therefore the coin holding body 9 cannot be rotated due to the held coin. This is the result.

In this embodiment, the horizontal shaft 3 is used as the motive force for delivering the product, but it is well known that the rotating shaft 3 connected to the operating knob 2 can also be used.

The operation of the above configuration will be explained below.

Let us now assume that the price is set at 400 yen, and that four hundred yen coins can be stored in the coin storage paths 9a, 9a of the coin storage body 9.

First, when 400 yen is inserted into an input slot (not shown) to purchase a product, the coin passes through a coin sorting device, flows out from the lower end opening 12 of the coin drop chute 11, and enters the coin receptacle of the coin holding body 9. The coins are stored in the coin storage path 9a through the entrance 10.

Then, the last coin C1 and the next preceding coin C2 are stored at a position facing the window 19.20 opened in the storage body 9.

In this state, when the operating knob 2 is rotated in one direction, for example, to the right, the coin holding body 9 is rotated counterclockwise in FIG. 2 via the rotation transmitter 6.

At this time, as shown in FIG. 5, the locking member 29 and the first locking member 22 come into contact with each other, and even if the locking member 22 attempts to enter the coin storage path 9a, the coin C1 prevents the locking member 22 from entering the coin storage path 9a. The movement is restricted and, on the contrary, the locking member 29 is pushed against the leaf spring 28 by the locking member 22.

Therefore, the locking member 29 is attached to the notch 25 of the ratchet plate 14.
The rotation of the operating gear 16 is now possible.

At this time, since the second locking member 24 is also biased by the leaf spring 23, even if the second locking member 24 attempts to enter the coin storage path 9a through the window 20, it is blocked by the coin C2.

Since the receiving protrusions 18, 18 of the holding body 9 are engaged with the protruding pieces 17, 17 of the ratchet plate 14, the operating gear 16 also rotates together with the holding body 9, so that the horizontal axis 3 also rotates.

At this time, due to the rotation of the holding body 9, the claw piece 9b engages with the hook portion 33a, and the coin holding member 33 moves to the left in FIG. After the connection is released, the spring 34 returns to its original state.

Therefore, as described above, when the horizontal shaft 3 rotates, the product delivery blade 3a fixed to the shaft 3 also rotates, making it possible to deliver the product.

At the same time, when the coin holding body 9 rotates approximately 180 degrees, the holding path 9
Let the coins in a fall under their own weight and store them in a safe.

Further, the roller 32 enters the recessed part of the cam plate 15 to stop the rotation of the operating gear 16, etc., and the locking member 29 again engages with the notch 25 of the ratchet plate 14 by the leaf spring 28, and the coin holding body 9 and the operating gear 16 stop rotating. The free rotation of the gear 16 is prevented - the vending operation is terminated.

Next, based on FIG. 6, the operation will be explained in the case where an attempt is made to take the coin without inserting a coin or when an attempt is made to play a trick by inserting 100 yen or 200 yen which is less than the set price.

As mentioned above, when the operation knob 2 is rotated, the rotation transmission mechanism 6
The coin holding body 9 is slightly rotated (by the play range) in the counterclockwise direction in FIG.

At this time, the first locking member 22 is pushed away by the locking member 29, and since there are no coins stored, the first locking member 22 closes the window 19 of the coin storage body 9.
The vehicle enters the reservation path 9a via the road.

That is, since the leaf spring 28 biasing the locking member 29 has a stronger biasing force than the spring 21 biasing the first locking member 22, the locking member 22 is not in the retention path 9a. enter in.

At this time, if it is attempted to further rotate the knob 2, the locking member 22 engages with the stopper 30 via the holding body 9.

Further, the second locking member 24 is also biased by the leaf spring 23 and the window 2
0 into the reservation path 9a.

Therefore, the coin holding body 9 and the operating gear 16 cannot be rotated, and the product is not discharged.

As described above, the present invention provides a coin holding body that temporarily holds coins through a rotation transmission mechanism by rotating an operating knob on the outside of the machine body when a plurality of coins are inserted, and a coin holding body that temporarily holds the coins through a rotation transmission mechanism. In a vending machine that can be sold when an engageable ratchet plate having ratchet teeth formed on its periphery rotates in a predetermined direction, among the coins temporarily held in the holding path of the coin holding body. We have opened two windows, one above the other and one above, facing each other, allowing you to view the final reserved coin and the next previously reserved coin.
A first member that can move forward and backward into the holding path from one side of the holding body through the one window and is biased in the exit direction by a spring.
a second locking member that can be moved forward and backward from the other side via the other window and is biased in the entry direction;
Also, a spring that can come into contact with the first locking member and has a stronger biasing force than the spring of the first locking member so as to engage the notch formed in the ratchet plate in the sales waiting state. The lock member is biased by the lock member.

Therefore, the tenth locking member cannot enter into the holding path due to the last held coin among the plurality of temporarily held coins, and the first locking member pushes the locking member. escapes from the notch of the ratchet plate, and since the second locking member cannot enter into the holding path due to the second to last held coin, the coin holding body and the ratchet are removed by rotating the operation knob. The board rotates in a predetermined direction and the product is sold.

In the conventional structure of a vending machine that can be sold by inserting a plurality of coins, for example, the coin holding body is unlocked by only the last inserted coin among the temporarily held coins, and the coin holding body and ratchet plate are unlocked. In the case of a structure in which the holding body is rotated, it was possible to unlock the holding body with a single coin depending on the timing of inserting the coin and rotating the operation knob. Since it was made possible to sell only when both the last reserved coin and the next reserved coin in the reservation existed, even if you tried to achieve the above timing with two coins, the first coin would receive less weight. It is extremely rare for both of them to be in a position where they can be seen from the window, and such mischief can be definitely avoided.
