The present invention relates to a vending machine, and when the coin is put into the coin input unit, the drawer is rotated 1/2 turn, and the sorting process and the withdrawal process of the coin are sequentially performed, so that the product can be easily withdrawn.

Conventional vending machines are divided into coin input unit, coin sorting unit, and product takeout unit.In case of mechanical type, the internal structure is complicated.In case of electronic type, the electronic circuit is connected to each part, so the price is high and breakdown. There are many defects that are difficult to operate in case of power failure and disconnection, and difficult to repair in case of failure.

The present invention provides an automatic vending machine that does not require an electronic circuit and power source to solve these shortcomings, but after coin input, the coin sorting and product withdrawal process is made by the rotation of each part coupled to the working shaft and driving shaft connected in a single axis. By making the structure simple, the manufacturing cost is low, and in case of failure, the repair will be described in detail with reference to the accompanying drawings as follows.

In the vending machine consisting of two product storage unit (2) attached to the inside of the case (1) and the product take-out unit (3) in which the operation draw (32) fixed to the product take-out cam 31 is fixed to the lower part, One side of the operation shaft 32 of the product take-out unit 3 and the square drive shaft 41 of the coin input unit 4 is connected to the side opening 5, but the pull-out handle 6 is connected to the other end of the square drive shaft 41. A plurality of rotary plates 7 and a plurality of diaphragms 8 are formed to be fixed to each other so that the insertion grooves 71 into which the coins 17 are inserted therebetween are fitted to each other so that each rotary plate 7 is fitted with a square drive shaft 41. To rotate together and to be fixed to the case (1) by fixing bolts (9) and rings (10) of each of the diaphragm (8) of the anti-rotation plate (11) coupled to the end of the square drive shaft (41) In order to rotate with the teeth, the ends of the stop lever 12 fixed to the diaphragm 8 are connected to each other by a spring 13, and a plurality of hollow portions 141 are perforated between the diaphragms 8. The top plate 14 is rotated by the fixed shaft 15 and the pin 16 is arranged in the hollow part 141 to restrict the rotation of each stopper 14 so that each rotary plate 7 is rotated and stopped. In the drawing, reference numeral 18 denotes a coin input groove formed in the diaphragm 8, 19 is a sales braking port stored in the product storage unit 2, 20 is a product withdrawal hole, 21 is a coin storage, 22 is a product, and 23 is an operating shaft. (32) is a support.

Here, the two insertion grooves 71 formed to correspond to the rotating plate 7 are formed to have the same outer diameter of the coin 17 according to the selling price of the product 22, and the number of the rotating plates 7 according to the total selling price. The increase or decrease is used to couple to the square drive shaft (41).

The present invention configured as described above has the coin 17 as introduced in the insertion groove 71 of the rotating plate 7 through the coin insertion groove 18 as shown in Figs. ) Rotate clockwise, the drawer handle 6 rotates the square drive shaft 41, and the rotating plate 7 rotates together with the square drive shaft 41 to move the coin 17 to the state of FIG. 4 (8). Will be moved. At this time, the outer diameter portion of the coin 17 pushes the stopper 14 counterclockwise, so that the end of the stopper 14 is displaced from the outer diameter of the rotary plate 7, that is, the end of the insertion groove 71. The rotating plate 7 is rotated one-half and the coin 17 is dropped into the holder 21 while the rotating plate 7 is rotated and the hooked portion 5 is connected to the square drive shaft 41 by the connector 5. The lower end product 22 in which the cams 31 of the actuating shafts 32 are laminated on the product storage unit 2 as shown in FIGS. Push back to draw the product withdrawal hole (20).

As described above, the coin 17 is inserted into the insertion groove 71 of each rotating plate 7 through the coin feeding groove 18, and then the drawer knob 6 is abducted by 1/2 so that two products 22 are provided. After the goods 22 are sold out, the brakes 19 stacked on the goods storage part 2 as shown in FIG. 3 (c) are located at the bottom end of the product storage part 2 of FIG. By the copper ball 19, the rotation of the cam 31 of the goods extraction part 3 is stopped, and even if the coin 17 is thrown in, the pull-out handle 6 will not be rotated. In addition, if the takeout knob 6 is rotated clockwise without inserting the coin 17, the stopper 14 rotates clockwise around the fixed shaft 15 by its own weight as shown in FIG. And the end of the pivoted stopper 14 is fitted into the insertion groove 71 of the rotary plate 7, so that the end of the stopper 14 and the inner end of the insertion groove 71 are not caught and are no longer rotated. ) Is not withdrawn, and when the takeout knob 6 is rotated in reverse, the teeth of the reverse rotation prevention plate 11 are caught by the end of the stop lever 12 as shown in FIG. ) Can be withdrawn.

In this way, when the user inserts coins and rotates the drawer knob by 1/2, the coins are sorted and goods are taken out sequentially at the moment of rotation. The structure is simple and the production cost is low. Is a useful design that is simple and easy to use.

Claims (1)

In the vending machine envisioned by the product taking-out part (3) in which the operating shaft 32, which is fixed to the two product storage part (2) and the product take-out cam 31 is fixed to the lower part of the case (1), One side of the operation shaft 32 of the product take-out unit 3 and the square drive shaft 41 of the coin input unit 4 is connected to the connector 5, and the pull-out handle 6 is fixed to the other end of the square drive shaft 41. And the plurality of rotating plates 7 and the plurality of diaphragms 8 formed therebetween so that the insertion grooves 71 correspond to each other, so that each of the rotating plates 7 and the plurality of diaphragms 8 are fitted to each other so that each rotating plate 7 It is rotated together with the square drive shaft (4) and the four sides of each diaphragm (8) to be fixed to the case (1) by the fixing ball (9) and the ring 10 and the reverse coupled to the end of the square drive shaft (41) The end of the stop lever 12 fixed to the toothed plate 8 of the anti-rotation plate 11 is connected by a spring 13 and a plurality of hollows 141 perforated between the diaphragm 8 The topper 14 is coupled to the fixed shaft 15 to be rotated, and the pin 16 is arranged in the hollow part 141 to restrict the rotation of each stopper 14 so that each rotary plate 7 is rotated and stopped.
