Grain Automatic Weighing Vending Machine {omitted}

The present invention relates to a grain vending machine that quantitatively measures and sells grains such as rice, barley, glutinous rice, beans, and red beans, and more specifically, is installed at the outlet side of the storage tank according to the accurate weighing of the load cell installed in the weighing container. The present invention relates to a grain automatic weighing vending machine which controls two motor drives to enable rapid grain weighing.

Due to the development of the industry, the family culture is changing to small families, and the number of working couples and singles is gradually increasing, so the dietary culture is changing. As a result, the demand for eating out and convenience foods is gradually increasing. Many families are eating rice.

However, in the current small family structure, the existing grain distribution method does not respond to such changes.

For example, a single or double working couple may have to buy more rice than they need to have a poor-quality meal after a long storage period, and buy small amounts while feeling the need for wholesome grains. As a result, there is a limit to the types of grains that consumers can choose in existing markets and retail stores.

Of course, some types of grains are packaged and sold in small quantities in department stores or large retail stores. However, several kinds of grains are packaged in small quantities, which is accompanied by many inconveniences in storage. .

Therefore, to solve this inconvenience, a grain vending machine for selecting and purchasing various kinds of grains has been developed and has been filed as a patent 2001-15762.

1 is a schematic view showing a structure of a conventional grain vending machine, which individually opens and closes outlets of a rice storage tank 1, a plurality of grain storage tanks 2, a rice storage tank 1, and a grain storage tank 2; Electronic switchgear (3a, 3b, 3c), rice polisher (4), hopper member (5) to collect and guide the rice and grains down, packing machine (6) for packing rice and grains, cash recognizer ( (7), selection button (8), rice detection sensor (9), grain detection sensor (10), collection box detection sensor (11), and the cash recognizer (7), selection button (8), each sensor (9) The controller 12 is configured to control the electronic switch 3a, 3b and 3c, the rice mill 4 and the packing machine 6 in response to the signals output from the (10) and (11).

The hopper member 5 collects the rice flowing out of the outlet of the rice mill 4 and the grains flowing out of the outlet of the grain storage tank 2 and guides them down, and flows out from the outlet of the grain storage tank 2. The first hopper (5a) to collect and guide the mixed grains, the rice flowing out of the outlet of the rice mill 4 and the grains flowing out of the outlet of the first hopper (5a) is collected and flows to the inlet to the packing machine (6) It is comprised by the 2nd hopper 5b.

Therefore, if a user who wants to use a vending machine of grains inputs a coin or a bill into a cash machine 7 and then selects rice in the process of pressing the selection button 8, the controller 12 recognizes this and the rice mill 4 Since driving the packing machine 6, the polished rice is transferred to the packing machine 6 in the rice cleaning machine, and then the work is finished after the packing is completed.

That is, after the rice or other grains flow into the packing machine 6 and outflow into the packaged product 20, the controller 12 stops the driving of the rice mill 4 and the packing machine 6.

However, the conventional packaging vending machine having such a structure has the advantage of supplying high quality rice to consumers because it sells rice on the spot, but it is necessary to have a separate rice mill in the vending machine, so the volume of the vending machine becomes large and space limitation due to installation Of course, there was a realistic problem that the sale of fresh grains is impossible due to the delay of waiting time according to the net.

In addition, the electronic switchgear is operated by pressing the selection button of the consumer so that the grain contained in the storage tank is discharged, so that it is impossible to accurately determine the amount of grain discharged, thereby reducing the reliability of the amount of grain discharged. There was a problem.

Moreover, there is a fatal defect that makes it impossible to withdraw grains when expensive electronic switchgear fails.

The present invention has been made to solve such a conventional problem, by improving its structure to install a measuring vessel equipped with a load cell directly below the discharge pipe connected to each storage tank so that it is possible to withdraw the correct amount of grain Its purpose is to.

Another object of the present invention is to ensure that the grains in each storage tank are initially discharged in large quantities, and then the grains of the value set in the load cell are discharged slowly until the final withdrawal is reached so that It is to make it possible to withdraw grains quickly.

Hereinafter, with reference to Figures 2 to 5 showing the present invention as an embodiment in more detail as follows.

Figure 2 is a perspective view schematically showing the structure of the present invention, Figure 3 is a longitudinal sectional view showing a storage tank of the present invention and Figure 4 is a cross-sectional view taken along line A-A of Figure 3, the present invention is in the body (not shown) Storage tanks 13a, 13b, 13c, 13d, and 13e containing different grains (rice, barley, glutinous rice, beans, red beans, etc.) are installed and stored on the outlet 14 of each storage tank. Discharge screw 15 for discharging grain in the tank is provided, the discharge screw 15 is fixed to the shaft 17 of the motor 16 installed on the outside of each storage tank is rotated as the motor is driven have.

On the outlet 14 of each storage tank 13, as shown in FIG. 3 and FIG. 4, only one discharge screw 15 is installed and the motor 16 for driving the discharge screw is made of grain. At the initial discharge, the controller rotates at high speed so that the grains contained in the storage tank can be discharged quickly, and then the motor 16 rotates at a low speed as the desired load cell 18 detects 80-90% of the withdrawal amount. By omitting), the grains in the storage tank can be discharged quickly even if only one motor 16 and the discharge screw 15 are installed.

However, as shown in FIG. 5, two discharge screws 15a and 15b are installed on the discharge port 14 of each storage tank, so that one discharge screw 15a is rotated by the high speed motor 16a. The other discharge screw 15b is configured to rotate by the low speed motor 16b so that two motors 16a and 16b are driven at the same time so that a large amount of grain is discharged and the load cell 18 is discharged. By detecting 80-90% of the drawing amount, the high speed motor 16a may be stopped and only the low speed motor 16b may be driven until 100% of the drawing amount is detected.

And the discharge pipe 19 is installed directly below the discharge screw 15 installed in each storage tank 13 so that the discharge port which is the end of each discharge pipe is collected at one time, and the measuring container in which grain is contained directly below the discharge pipe. 20 is installed, and one side of the weighing container is provided with a load cell 18 for controlling the driving of the motor 16 by measuring the weight of the grain contained in the weighing container.

The shutter 21 for opening and closing the lower portion of the measuring container is installed directly below the measuring container 20 so that the load cell 18 detects that a predetermined amount of grain is discharged to the measuring container and stops driving the motor 16. After that, the shutter 21 opens the lower portion of the weighing container by driving the driving means 22 to discharge the grains from the weighing container 20, and a hopper 23 is placed below the weighing container 20. As the grains in the weighing container 20 fall freely, a well-known packing machine 24 for automatically packing the grains and discharging them to the outlet side is provided.

As the driving means 22 for moving the shutter 21 to one side, a cam plate that rotates according to the driving of a cylinder or a motor is applicable.

Since the configuration of the packaging machine 24 is not different from the configuration of the known packaging machine, a detailed description thereof will be omitted.

Referring to the operation of the present invention configured as described above are as follows.

First, when a consumer inputs a certain amount of money to purchase a desired grain and presses a selection button (not shown) according to the type of grain, the control unit calculates the amount of money inputted according to the price of the selected grain, and then selects the selected amount. Since the motor 16 is driven on the storage tank 13 containing the grain, the discharge screw 15 fixed to the shaft 17 of the motor rotates.

Accordingly, the grain in the storage tank 13 is discharged along the discharge pipe 19 to be contained in the metering vessel 20. In this process, when only one motor 16 is installed on the storage tank 13, the motor When the high speed motor 16a and the low speed motor 16b are installed, the two motors 16a and 16b are driven at the same time so that a large amount of grain is stored in the storage tank 13 at the initial discharge of the grain. Eject quickly from.

As the grains in the storage tank 13 are contained in the weighing vessel 20 through the discharge pipe 19 by the operation as described above, the load cell 18 detects the weight of the grains 80-90 of the grains to be purchased by the load cell. When it is detected that the percentage has been reached by the control of the control unit to rotate the motor 16 that rotates at high speed at a low speed.

On the other hand, when the high speed and low speed motors 16a and 16b are installed in the storage tank 13, the high speed motor 16a is stopped and the grains in the storage tank 13 are gradually discharged to the weighing container 20 side. This is to allow more accurate weighing of the grains withdrawn from the storage tank 13.

As described above, when the load cell 18 detects that the grain in the storage tank 13 is gradually discharged to contain a certain amount of grain to be purchased in the weighing container 20 and the driving of the motor 16 is stopped under the control of the control unit. Since the shutter 21 installed on the bottom surface of the weighing container 20 moves to one side by a cam plate rotating according to the driving of a cylinder or a motor to open the lower part of the weighing container, grains in the weighing container are transferred to a known packing machine 24. At the same time it is packaged by the cutting is taken out through the outlet (not shown) located in the lower it will be more convenient for consumers to purchase the desired grain.

As described above, the present invention is provided with a weighing container equipped with a load cell directly below the discharge pipe connected to each storage tank, so that accurate amount of grain can be taken out, so that the consumer's reliability can be greatly improved. do.

In addition, a large amount of grain is quickly discharged during the initial discharge of the selected grain during the purchase of the desired grain by the consumer, and the discharge rate is slowed down when the discharge is almost completed, so that the correct amount of grain is measured in a shorter time. It provides the convenience of being able to purchase.
