Description

Coin injection machine of the vending machine that can insert coins of different sizes {Copper injection chapter of vending machine}

The present invention relates to a mechanical coin dispenser of a vending machine that can insert a plurality of coins at a time.

In general, the vending machine is provided with a coin injector in the front to receive the desired product if you put a coin in accordance with the price of the product being sold.

In the conventional vending machine coin dispenser structure, there is an operating wheel 3 provided with a coin mounting groove 4 inside the cover frame 1 having a coin inlet 2 as shown in FIG. The shaft S which rotates (3), the operation lever R which rotates the shaft S, and the sensor piece 5 which discriminate | determine the specification of the coin put and conveyed are provided. The sensor piece 5 has a property of being inserted into the moving path of the coin mounting groove 4 by the elastic force of the spring 6, and is caught by the top end of the coin mounting groove 4 facing the top to prevent rotation. The jaw 7 is formed.

Injecting a coin into the coin injector of such a configuration and then rotate the operating lever (R) shaft (S) to rotate the operation wheel (3) and the coin mounted with it is also transported with rotation. The coin to be transported is rotated while lifting the sensor piece (5), if the size of the coin is small, the lifting jaw (7) is caught on the top of the coin loading groove (4) can not lift the sensor piece (5) completely The rotation of the wheel 3 is blocked, and if the size of the coin is larger than the standard, it is caught at the trajectory entrance to which the coin is initially inserted and is caught at the lower end of the sensor piece 5 which is blocked or lifted so that it cannot pass inside, and is discharged again to the outside. There is no choice but to make it.

However, such a conventional coin dispenser has a coin loading groove 4 formed in the coin inlet and the operation wheel not only has a size to input a single coin, but also a sensor for discriminating a coin also has a structure for discriminating only one coin. Only coins can be put into each one. For this reason, the buyer has to inject coins several times when using the vending machine, which causes inconvenience such as delayed time for withdrawing the goods.

In addition, there are cases where coins of different sizes are put in accordance with the price of the goods being sold. At this time, there is no device to determine this, which inevitably raises or lowers the price so that only coins of the same size can be put.

The present invention is devised to solve the shortcomings of the conventional coin injector to be put only one coin.

The purpose of the present invention is to improve the structure of the coin-mounting groove of the operation wheel and the discrimination device for determining the standard of the coin so that a plurality of coins of different sizes can be superimposed and put into the vending machine quickly and easily. It is to provide a vending machine coin dispenser which can make it possible and recognize it stably without error.

As shown in the drawings, the configuration of the coin injector 10 of the present invention includes a cover frame 11 having a coin inlet 12 and an operation wheel 20 for transporting coins into the cover frame 11. And a coin support piece (26a, 26b) for supporting and fixing the inserted coin, the support plate (50) for supporting them, the discriminating device (30) for sensing the size of the coin when the inserted coin is transferred, and to prevent the reverse rotation A ratchet device, a shaft S for rotating them, and a drive gear 70 for operating the vending machine drive by the complete rotation of the shaft S, these operating wheels 20, and coin support pieces 26a, 26b. , Shaft (S) is formed in the center of the ratchet device and the drive gear 70 is inserted into it to control the integral rotation.

The cover frame 11 has a coin inlet 12 at the center as a part exposed to the outside. Since the coin inlet 12 has a structure that penetrates to the lower portion thereof, a guide portion 13 is formed at an upper portion thereof to facilitate the input of coins, and the guide portion 13 has a structure that protrudes to the rear side. And the coin inlet 12 has a size as much as the coin thickness can be inserted at one time to enable a plurality of inputs.

An operating wheel 20 is installed at a lower portion of the coin inlet 12, and the operating wheel 20 is provided with coin mounting grooves 22a and 22b for mounting coins introduced from the coin inlet 12. Coin-mounted grooves (22a, 22b) is a coin that is divided into sizes according to the price to expand the width of the coin is added according to the price plus the thickness of the other coins in order to be able to stack a plurality of coins It is formed according to the standard. In other words, a coin of large size enters inside, and a coin of small size enters in front thereof, and coin mounting grooves 22a and 22b are provided for each coin size in the same number as the number of coins.

In addition, since the lower part of the coin mounting grooves 22a and 22b has an open structure, the coin supporting pieces 26a and 26b are installed at the lower part so as to support the lower part of the coin. The coin support pieces (26a, 26b) is not only to support the lower part of the coin but also to maintain the height of the coins to be stable, there is also a body composed of one body and the same number as the number of coins is installed, It is preferable that the coin is installed in a one-to-one correspondence structure.

In addition, the gap between the upper end of the coin mounted in the coin mounting grooves 22a and 22b and one end 14 of the coin inlet 12 in the rotational direction of the operation wheel 20 and the alignment jaw 35 is almost close. It is desirable to have. This is to initially block the input of coins larger than the standard.

Determination device 30 for determining whether the coin is the standard coin is installed on the back of the cover frame 11 as shown in Figure 5, in particular located on the side of the coin inlet 12 in the direction in which the operating wheel 20 is rotated do.

The site where the discriminating device 30 is installed is open so that the sensor pieces 32a and 32b can be in contact with the circumference of the operation wheel 20, and the sensor pieces 32a and 32b are located near the coin inlet 12. An alignment jaw 35 is formed to protrude from the engaging jaw 34 formed at one end. By this alignment jaw 35, the sensor pieces 32a and 32b are aligned to a suitable depth without difficulty in conveying coins.

In addition, on the opposite side of the alignment jaw 35, a shaft groove 36 is formed to axially rotatably couple the sensor pieces 32a and 32b at a predetermined angle. The shaft groove 36 has a side opening toward the alignment jaw 35 so that the sensor pieces 32a and 32b to be described later are rotatably coupled within a predetermined angle through the opening. The shape is like a structure having a longitudinally long incision in the side of the cylinder.

The sensor pieces 32a and 32b have a structure in which a circular pivot shaft 33 is formed at one side and a locking step 34 is caught at the alignment jaw 35 at the other side. At this time, the pivot shaft 33 simply forms one end of the sensor pieces 32a and 32b in a circular shape, and has a constricted connection portion between the pivot shaft 33 and the sensor pieces 32a and 32b. The pieces 32a and 32b stack and insert the sensor pieces 32a and 32b in such a manner as to couple the circular pivot shaft 33 to the above-described shaft groove 36 by positioning the narrow connection portion at the opening of the connection groove.

In addition, a spring 37 is provided on the rear side of the sensor pieces 32a and 32b to push the sensor pieces 32a and 32b toward the operation wheel 20. In particular, the springs 37 are provided for the respective sensor pieces 32a and 32b. 32b) to have a one-to-one correspondence.

This sensor device is particularly important because the structure of the coin mounting grooves (22a, 22b) of the operating wheel 20 is determined because the determination is made in connection with the operation wheel 20, the function of discriminating coins, not the standard. That is, the sensor piece of the sensor device (to be described later) is large so that it is caught on the lower ends of the sensor pieces 32a and 32b so as not to pass therethrough, and when the size of the coin is small, the coin-mounting groove of the operation wheel 20 ( This is because further rotation is blocked in conjunction with the upper end of the rear side (position based on the rotating direction) of 22a and 22b).

Therefore, importantly, since the coins of different sizes to be fed and transported are simultaneously introduced in a superimposed state, the sensor pieces 32a and 32b for discriminating them must be individually configured, and in the form of the coin mounting grooves 22a and 22b. Accordingly, the position of the sensor pieces 32a and 32b, that is, the depth projecting into the coin transfer trajectory should be adjusted.

If the coin height is kept constant, the positions of the sensor pieces 32a and 32b may be the same. In this case, however, the position of the coin support pieces 26a and 26b at the bottom of the coin-mounting grooves 22a and 22b into which the small coins are inserted is increased by the coin size difference, so that the height of the top of the coin is designed to be the same.

On the other hand, if the height of the coin mounting groove (22a, 22b) is variable, as well as the size of the coin, the sensor piece (32a, 32b) corresponding to each coin is also inevitably variable position. That is, the small sensor pieces 32a and 32b are formed so as to protrude in the movement trajectory of the coin smaller in size than the sensor piece that is responsible for the large sensor pieces 32a and 32b. As a result, the alignment is different. At this time, the rear end of the coin mounting groove on which the small coin is mounted is slightly lower than the rear end 24 of the large coin mounting groove 22a, and when the standard coin passes, the ends of the sensor pieces 32a and 32b are coined. It is preferable not to be caught by the rear end 24 of the mounting grooves 22a and 22b.

At this time, the coin mounting grooves (22a, 22b) of the operation wheel 20, the rear upper end 24 is configured slightly higher than the tip. The height may vary depending on the structure of the sensor pieces 32a and 32b of the determination device 30 to be described later. Therefore, when the operation wheel 20 rotates in a state in which the sensor pieces 32a and 32b are not lifted to an appropriate height, the ends of the sensor pieces 32a and 32b are coin-mounted grooves 22a and 22b of the operation wheel 20. It is caught on the rear top 24 of the to prevent rotation.

And the lower end portion 321 of the sensor piece (32a, 32b) in close proximity to the pivot shaft 33 is mounted on the coin mounting groove (22a, 22b) even if the sensor piece (32a, 32b) has the maximum rotational state It is designed to keep the distance very close to the top of the coin. This is to block the input of coins larger than the standard. When coins larger than the standard are inserted, the sensor pieces 32a and 32b are rotated to prevent the rotation of the operation wheel 20. The lower end 321 of the 32a, 32b is to prevent the rotation further.

In addition, in order to provide more reliability to the sensing function of the sensor, the separation plate 28 may be installed by aligning the intervals of coins inside the coin mounting grooves 22a and 22b. In other words, the distance between the coin and the coin so that the sensor piece (32a, 32b) does not interfere with the adjacent coin to ensure the reliability of the discrimination function.

At this time, the separation plate 28 may be integrally formed in the coin-mounting grooves (22a, 22b) as shown in Figure 4c, as shown in Figure 4b by forming a plurality of coin support pieces (26a, 26b) to correspond to each coin one-to-one It may be configured to be separated and coupled to each other through the separating plate 28 between the coin support pieces (26a, 26b).

In addition, the secondary discriminating unit 40 having the same structure may be sequentially formed on the rear side of the discriminating device in order to increase the accuracy of the discriminating operation.

On the other hand, the support plate 50 for supporting these devices is screwed to the back of the cover frame 11 on the rear side where the discriminating device 30 and the operation wheel 20 are installed. The central portion of the support plate 50 is open, through which the ratchet device is axially coupled to the shaft (S) is rotated together. The ratchet device is provided with a ratchet wheel 60 which is axially coupled to the shaft, and the ratchet 64 is engaged with the teeth 62 of the ratchet wheel 60 by the ratchet spring 65 on the support plate 50. The wheel 60 is rotated in only one direction, and the driving gear 70 for operating the driving device of the vending machine is rotated together with the operation wheel 20 to be coupled together to rotate the shaft hole in the center shaft (S). It is installed.

In particular, since the ratchet wheel 60 does not have the teeth 62 in the section in which the discriminating device 30 is located in the initial state, the ratchet wheel 60 can be rotated back to the initial state.

Looking at the operating state of the subject innovation by this configuration as follows.

When the coin is placed in the initial state, that is, coin mounting grooves 22a and 22b coincide with the coin inlet 12, the coin is large, as shown in Figs. It is aligned with the mounting grooves 22a and 22b. At this time, when the separating plate 28 is located in the coin mounting grooves 22a and 22b, the separating plates 28 are positioned between the coins so that the coins are aligned at a predetermined interval. If the bent or bent coins are put in the same state because the thickness is thickened it is impossible to initially put in the coin mounting groove (22a, 22b).

Rotating the operating lever (R) in the state where the coin is mounted while rotating the shaft (S) operating wheel 20, ratchet wheel 60 and the drive gear 70 at the same time.

When the operation wheel 20 rotates in the forward direction, the coin mounted in the coin mounting grooves 22a and 22b is primarily passed through the lower end of the coin inlet 12. At this time, since the end of the coin inlet 12 is very close to the height of the coin inserted, if the coin is larger than the standard does not pass because the first operation wheel 20 can not rotate anymore, the coin does not meet the standard Can be filtered first.

When the coin passes through the end of the coin inlet 12, it is in contact with the sensor piece (32a, 32b) aligned with the alignment jaw 35 and aligned in the trajectory through which the coin moves, while passing through the sensor piece (32a) as shown in Figure 6b , 32b). In this case, when the size of the coin is less than the standard size, the sensor pieces 32a and 32b cannot be lifted to the specified height, so that the upper end of the rear side of the coin-mounting grooves 22a and 22b that the ends thereof subsequently approach as shown in FIG. 6C. (24) is caught and can no longer rotate.

In addition, when the coin has a size larger than the standard, the upper end of the coin is caught by the lower end 321 of the raised sensor piece, as shown in Figure 6d will not pass through.

In addition, when the thickness of the coin to be fed and conveyed is thin, it is caused to flow left and right by the sensor pieces 32a and 32b protruding in the coin trajectory by the elastic force of the spring 37 to move the sensor pieces 32a and 32b. As a result, the rear end 24 of the coin mounting grooves 22a and 22b of the operation wheel 20 is caught by the ends of the sensor pieces 32a and 32b so that rotation is no longer blocked. Therefore, even thin coins can be effectively identified.

If the size of the coin is larger than the standard, the first coin passed through the lower end of the coin inlet 12 is secondly blocked again by the lower end of the sensor piece (32a, 32b). That is, even if the sensor pieces 32a and 32b are lifted by coins, the lower end of the sensor pieces 32a and 32b is always close to the height of the standard coins so that coins larger than the standard cannot pass and are blocked by the sensor pieces 32a and 32b. .

In particular, in this operation, when the separating plate 28 is configured between the coins mounted there is a certain space between the coins and coins, so each coin corresponds one-to-one to each sensor piece (32a, 32b), so that adjacent coins It does not interfere with other adjacent coins, which can increase the accuracy of the coin specification.

In addition, when the sensor pieces 32a and 32b are lifted by coins, they move while compressing the springs 37, and when the coins are removed, the sensor pieces 32a and 32b return to their original positions. ), Since the other sensor pieces 32a and 32b, that is, the coins pieces 32a and 32b corresponding to one-to-one correspondence with each other, are independently identified and operated, the reliability of the coin specification is secured. .

As such, when the coin is blocked, the operation wheel 20 is in the absence of the teeth 62 of the ratchet wheel 60, so the reverse rotation is possible, so that the reverse rotation is performed in the initial state to discharge the defective coin.

If the coin mounted in the coin mounting grooves 22a and 22b of the operation wheel 20 passes through the sensor pieces 32a and 32b entirely, it is sensed again by the secondary discrimination apparatus 30 in the same manner, and passes through When it is removed from the coin mounting groove (22a, 22b) by the weight is discharged to the coin box along the guide, the operation wheel 20, ratchet wheel 60 and the drive gear 70 is rotated 360 ° to return to the initial state do. By this operation, the drive gear 70 drives the driving device for discharging the goods of the vending machine to provide the goods.

As described above, the present invention has a coin loading groove formed on the operation wheel of the coin puter so as to have a width corresponding to the thickness of the coin put in a layer and an error according to the one-to-one correspondence of the sensor piece of the discriminating device for determining the standard. Without having a function that can accurately determine the quantitative coin that does not perfectly meet the standard, it is possible to put a plurality of coins at a time, and thereby has the advantage that the coin can be carried out quickly and simply.
