(54) DEVICE FOR ISSUING COINS

one

The invention relates to monetary. mechanisms installed in vending or other vending machines and is intended for issuing coins of various denominations as a change in the payment of 5 lats for goods (services) dispensed by the machine or for exchanging a received coin into coins of lesser value.

A coin dispenser is known, comprising vertical coin cassettes 10 and an ejector having reciprocating motion in a horizontal plane. The device provides for the issuance of a single ejector coins from several. 5 placed in one row of cassettes 1.

The disadvantage of such a device is low productivity due to the loss of time to reverse, idling. 20

The closest technical solution is a coin dispenser, comprising vertical cassettes mounted on a base, on which a 25-driver ejector is fixed and a roller with a spring.

The drawback of the device is the low productivity, complexity of the device, since for each kdset two ejectors are required, 30

and only one works. In addition, there is not always a good adhesion of the ejector to the coin, especially if the coin is deformed, there is no control over the coins.

The aim of the invention is to increase the reliability and performance of the device.

This goal is achieved by introducing photoelectric converters, an electromagnet, a rod and a shutter, rigidly connected to the ejector at an angle to it, an electromagnet through a rod and a spring connected to the ejector, which is placed between two cassettes and made with a protrusion. whose height is less than the minimum thickness of the coin, photoelectric converters are electrically connected to electromagnets.

FIG. 1 and 2 the proposed device is shown; 3 - key tab.

The coin dispenser contains a base 1, on which, for example, cassettes 2 are placed in two rows, an ejector equipped with a Zyos-existing drive, rotating an ejector, an electromagnet 4 controlling the operation

ejector; photoelectric converters 5. Cassettes 2 are made in the form of cylindrical tubes for stacking horizontal coins with radius grooves a in the bottom.

Between each pair of cassettes is placed an ejector, which is a hollow roller 6, at one end of which a radius key 7 with a projection b (fig. 3) is hinged for engaging with the coin and withdrawing it. The height of the protrusion is determined by the thickness of the coin. The key and the protrusion have a slope that provides a reliable grip even with a deformed coin, the height of which is placed in the maximum thickness of the coin. The key 7 is provided with a shutter 8 made in the form of a thin plate and placed under the protrusion of the key with a radius of rotation greater than the radius of rotation of the key half a diameter of the coin. The shutter provides overlap of the photovoltaic converter 5 installed near each cartridge in the exit zone of the coin and the shutter 8 of the ejector from the cartridge. Sht B is located under the key 7, below the bottom. cassette. On the key there is a roller 9, fixing the depth of the key protrusion entering the cassette. The movement of the key restricts the stop 10. Inside the roller is placed the rod 11, which through a flat spring 12 puts the key in the position of issuing a coin. The rod 11 is moved downwards by the electromagnet 4, and the spring 13 is returned.

The device works as follows.

Coins are preloaded manually or automatically placed in cassettes. The drive is turned on. The ejector starts to rotate constantly in one direction along the arrow (Fig. 2). In the case of coins, only from one cassette after passing the shutter in the photoelectric converter zone of the opposite cassette, an enabling signal to turn on the electromagnet is given. The anchor of the electromagnet 4 lowers the rod 11, which presses on the spring 12 and raises the key; when it is rotated, it coalesces with the coin and one coin is emitted. After the passage of the coin and the shutter, the photoelectric converter issues two pulses, confirming the passage of the coin ,. The possibility of picking up two pulses allows you to control the issuance of a coin. In the case of a photoelectric converter with only one pulse, the passage of one ejector is noted. After confirmation of the coin issue by the photoelectric converter, the electromagnet is turned off. When the coin is re-issued from the same cassette, the lowered key passes under the opposite cassette in the area of its photoelectric converter, the electromagnet turns on and the raised key removes the second coin, if necessary, the coins are not turned off from the Two cassettes, and the key alternately turns in one turn gives out a coin from two cassettes.

The key is raised and lowered with a rotating ejector, and the key lifting time is much less than the time it takes the ejector to turn to the opposite cash register where the coin is issued.

The use of one ejector on two cassettes reduces the size and simplifies the design of the device for extracting coins of several denominations. The number of ejectors will be halved.

 If a handler is used to hand over a change, the likelihood of errors in handing out a hand or changing coins will be reduced due to the presence of control over the output of coins from the cassette with increased productivity.
