Description

Rack Forward, Reverse Rotation Control Apparatus for Vending Machine}

The present invention relates to a rack rotating device of an automatic vending machine that sells various goods, in particular, to sell a plurality of products in one vending machine to rotate a plurality of racks in the forward and reverse directions to enable the fastest product discharge according to the situation. It relates to a rack forward and reverse rotation control device of a vending machine.

As is well known, a vending machine that sells a variety of products in one vending machine is widely used and is widely used. Looking at its structure, the vending machines are filled with a plurality of racks arranged vertically. Is rotated by the rotating rod installed in the center is that the product is selectively discharged through the outlet formed in the bottom of the rack when the rotation is stopped by the motor. Therefore, to discharge the goods from the selected rack was to cause inconvenience because the rack loaded with the selected goods must wait until the goods outlet is reached.

It is an object of the present invention to provide a vending machine forward and reverse rotation apparatus that allows a rack selected from a plurality of racks to reach the outlet upwards most quickly in order to solve this problem.

In order to achieve the above object, the present invention rotates a plurality of racks installed in one enclosure so that the selected rack is stopped above the outlet, and the direction in which the outlet can be quickly reached above the rack according to the position of the rack. This paper proposes a rack forward and reverse rotation device of a vending machine that stores the rotation angle and the rotation angle in a memory and reads it out by a microprocessor so that the selected rack can reach the top of the outlet in the shortest time.

Accordingly, in the present invention, the rack loaded with the product selected by the consumer can reach the outlet upwards in the shortest time, so that the consumer can quickly and quickly release the selected product at the same time as pressing the selection button of the product. Will be.

Referring to the present invention in more detail with reference to the accompanying drawings as follows.

1 and 6 show the overall configuration of the present invention. As can be seen from the present invention is to select a product corresponding to the amount of money detected by the coin discriminator (2) and the coin discriminator (2) to recognize that the coin is inserted into the coin inlet (1) and banknote inlet And a rack 10 on which a selected product among the plurality of racks 10, 10 ', 10 ", 10"' is loaded by the selection of the selection button 3 and the selection button 3. With a microprocessor 7 and a driving circuit 8 for driving the motor 5 so as to reach the motor, and a rotating shaft 6 installed in the center of the plurality of racks 10 to rotate the plurality of racks 10 In known ones,

The index switch 12, which is stepped once by the rotary cam 11 and rotated once per 1 / n (the number of racks) by the operation of the motor 5, is installed at the center of the rack 10 and rotates electrically. The cam switch 14 intermittently intermittently rotated by the rotation cam 13 interlocked by the cam 11 and the index switch 12 and the cam switch 14 are connected to the input port. The processor 7 and the memory in which the rotation direction of the motor 5 and the data map in which the number of times of the index switch 12 are specified are stored according to the product selected by the consumer.

According to the present invention as described above, when a consumer inputs coins or bills corresponding to the price of a product into a currency discriminator (2), the microprocessor (7) detects this and the product corresponding to the input amount is supplied. Which one is displayed.

When the consumer presses the selection button 3 of the desired product, the microprocessor 7 recognizes this and rotates the rack associated with the selection button 3 to move above the outlet 4.

To this end, the microprocessor 7 must know which position the rack currently selected by the selection button 3 is in place, and for this purpose it is inserted into the groove 16 'of the cam 16 fixed to the rotating shaft 6 or turned off. The state of the cam switch 14 is detected.

If the initial setting is set to the rack 10 number 1 with the cam switch 14 turned on by the groove 16 'of the cam 16, the consumer may load the goods in the rack 1 rack 10. When selected, the microprocessor 7 causes the cradle to be released by the motor on the top of the rack 10 without rotating the rack 10 by the data map of the memory as shown in FIG. To allow the product to be discharged immediately (see Figure 5 "A").

In addition, when the next consumer selects the product of rack 4, the microprocessor generates contact points of the index switch 12 in the counterclockwise direction by referring to the present position 1 using the map data stored in the memory. After rotating the rotating shaft (6) until the operation is stopped. As a result, the goods of rack 4 are located above the goods outlet, and the microprocessor 7 shows that the number 4 of the goods rack 10 is located directly above the goods outlet 4. I will remember. In this manner, the clamp is released by the motor at the top of the rack 10 and the outlet driving means is operated to immediately discharge the goods. (See FIG. 5 "b").

Subsequently, when the consumer selects the product of the product rack 10, the product rack stored in the microprocessor 7 is located in position 4, so that the rotating shaft 6 is rotated counterclockwise using the memory map. In this case, the index switch 12 stops the operation after the single-speed operation is performed once (see FIG. 5 "C").

In this way, the present invention can minimize the time required to rotate to selectively discharge the different kinds of goods loaded on the plurality of racks 10, so that the time required for the discharge of the product selected by the consumer can be greatly shortened. Will be.

In addition, although the example shown using four racks 10 is shown in the above-described embodiment, it is possible to add or subtract as needed. For this design change, the index switch 12 corresponds to the number n of racks 10. Of course, to be intermittent every 1 / n revolutions.

In addition, in the present invention, the rotating cam 13 having the grooves 13 'arranged at a plurality of uniform intervals so that the index-position 12 is interrupted every 1 / n revolution and the pins 15 and 15 interlocked therewith. It is possible to implement in the form having a rotary cam 11 having a ') and an index switch 12 operated by the groove 11' of the rotary cam 11. In this embodiment, when the motor 5 is operated while the index switch 12 lever is inserted into the groove 11 ′ of the rotary cam 11, the rotary cam 11 is interlocked with each other. The pins 15 and 15 'rotate the rotating cam 13 by the rotation. As a result, the rotary shaft 6 coaxial with the rotational cam 13 rotates, and the cam 16 rotates to operate the cam switch 14. According to this structure, the number of times of the rack 10 is reversed. The number of the grooves 13 'and the interval between the pins 15 and 15' are designed so that the rotation cam 11 rotates one rotation when it is rotated by one value. ) To g).

As can be seen from the present invention, the rotation cam 13 is rotated by the rotation cam 11 rotated by the motor 5 as shown in Figure 4 a), as shown in Figure 4 b). When the pins 15 and 15 'of the rotary cam 11 are fitted into the grooves 13' of the rotary cam 13, the rotation cam 13 continues to rotate by the pins 15 and 15 '.

Subsequently, the rotational cam 13 is continuously rotated by two pins 15 and 15 'as shown in FIGS. 4 c) and d), and the groove of the rotary cam 11 is shown in FIG. 4 e). The index switch 12 lever is inserted into the position 11 ', and this state is rotated counterclockwise.

If the rotation continues in such a state, as shown in Fig. 4 (f), g), the rotation cam 13 rotates by 90 ° every one rotation of the rotary cam 11, and the index switch 12 lever is operated. .

In this way, the present invention can minimize the time required for discharging the product in the discharge of the specified product according to the consumer's choice by loading several kinds of goods in one enclosure useful effects that can facilitate the user's convenience There is.
