It consists of the drive part 200 which drives SV20. In particular, the balance scale 2 is configured as a differential transformer to more finely measure the weight of the container and the raw material contained in the container.

The operation of the present invention configured as described above will be described.

When the operation of the system is started with a fragment of the selection panel, which is not shown, the PLC 100 checks which of the programs stored in the memory is mixed with a plurality of raw materials. That is, the PLC 100 checks which of the programs for producing different products is selected to produce a product, and reads a database corresponding thereto to read a plurality of raw materials (in the present invention, six raw materials will be described as an example. The number of raw materials varies depending on the product to be produced).

Of course, the display unit displays data on the selected product or the mixing ratio (weight) of the raw materials for producing the product, such as a monitor not shown so that the operator can check it.

And it is confirmed whether the monorail transfer (3) is located at the starting point of the rail (5). At this time, the position of the monorail transfer 3 is determined by the PLC 100 to recognize the operating state of the micro switch installed on the starting line of the rail 5.

When it is determined that the mono rail transfer 3 is located on the starting line of the rail 5, the PLC 100 detects the container (s) detected by the balance scale 2 seated on the upper part of the mono rail transfer 3. According to the weight of 1), it is checked whether the container 1 is seated on the upper part of the monorail transfer 3, furthermore, the weight of the container 1 before the raw material is contained, and this is the PLC 100 Will be stored inside.

In addition, the PLC 100 outputs a driving signal to the driving unit 200 to drive the motor M1 installed in the monorail transformer 3 so that the monorail transfer 3 moves along the rail 5. Do it. At this time, the movement distance of the mono rail transfer 3 by the motor M1 is to stop when the mono rail transfer 3 is located below the first storage hopper 4a, which is the first of the mono rail transfer 3 The driving of the motor M1 is controlled under the control of the PLC 100 which recognizes the operation state of the micro switch M / S1 installed to operate when located below the storage hopper 4a.

When the monorail transfer 3 on which the container 1 is seated is positioned under the first storage hopper 4a, the PLC 100 outputs a control signal to the drive unit 200 to thereby provide the inside of the screw feeder 7a. A pair of motors (M2) installed in the operation of the balance scale is mounted on the upper portion of the monorail transfer (3) while the raw material stored in the storage hopper (4a) and the hopper guide (6a) is introduced into the container ( The weight change state of the container 1 detected by 2) is recognized.

The weight of the first raw material input to the container 1 is calculated by subtracting the weight of the first detected container from the weight of the continuously changing container 1, and comparing the weight of the first raw material with the weight set in the database. It is determined whether the amount is correctly input. This operation continues until the first raw material is input by the set amount, and when the input of the first raw material is finished, the operation of the screw feeder 7a is stopped and the preparation for the second raw material is made.

At this time, the PLC 100 drives the solenoid valve SV5 and SV6 to control the amount of raw material discharged by the screw peter 7a interlocked with the pair of motors M2, while driving the solenoid valve SV. By driving the air vibrator 30 is configured on the side of the hopper guide (6a) so that the raw material stored in the storage hopper (4a) and the hopper guide (6a) can be lowered more smoothly.

In the present invention, since a plurality of storage hoppers (4a) (4b) (4c) (4d) (4e) (4f) in which the raw materials are stored are installed on the same line in pairs of two, the mono raw material is finished after the input of the first raw material is finished. After only stopping the operation of the first screw feeder 7a without moving the rail transfer 3, the second screw feeder 7b is operated again to obtain the raw materials stored in the storage hopper 4b and the hopper guide 6b. As described above, the container sensed by the balance scale (2) and the weight of the raw material input thereto are sensed as described above, and then the weight of the container at the time when the first raw material is finished is subtracted from the second. The input weight of the raw material is recognized.

Then, the screw feeder 7b is operated until the weight of the second raw material is equal to the weight of the second raw material in comparison with the weight of the second raw material set in the database. Of course, as described above, the solenoid valve SV7 and SV8 are operated to adjust the input amount of the raw material, and the vibrator 30 is operated to store the raw material stored in the storage hopper 4b and the hopper guide 6b. Go down smoothly. In the following description, since these operations are the same, they are omitted.

After finishing the input of the raw materials stored in the first and second storage hoppers 4a and 4b and the guide hoppers 6a and 6b, the motor M1 installed in the monorail transfer 3 is operated to operate. While moving the monorail transfer 3, check whether the micro switch M / S2 installed on the rail 5 of the lower part of the third storage hopper 4c, 4d and the guide hopper 6c, 6d is operated. do.

After the micro switch M / S2 is in operation, the motor M1 is stopped and the raw materials stored in the storage hoppers 4a and 4b and the guide hoppers 6a and 6b are put into the container 1 as described above. Then, the motor M1 is driven again to move the monorail transfer 3, and then the fifth and sixth raw materials are introduced at the point where the micro switch M / S3 is operated. In this case, the weight of the raw material contained in the container 1 is sensed, and the weight of the previously detected container 1 and the raw material wrapped in the container is subtracted from the weight of the currently input raw material to recognize the weight of the raw material. To control.

Here, the shoe 31a, 31b, 32c provided in the middle of the hopper guides 6a, 6b, 6c, 6d, 6e, 6f in pairs is screwed under the control of the PLC 100, respectively. The feeders 7a, 7b, 7c, 7d, 7e and 7f are operated so that the fine powder raw material is stored in the storage hoppers 4a, 4b, 4c, 4d, 4e and 4f. It serves to absorb the powder generated when introduced into the container 1 from the guides 6a, 6b, 6c, 6d, 6e, and 6f. That is, while discharging the raw materials stored in the storage hoppers 4a, 4b, 4c, 4d, 4e, and 4f, the solenoid valve, not shown, is operated under the control of the PLC 100, and the flow of air is controlled by the powder filter. In this case, the powder generated as the raw material is introduced is collected by the shoes 31a, 32b, and 3c, and is introduced into the powder filter and filtered. Accordingly, the raw material in the powder state is added to the inside of the container where the weighing is finished, thereby preventing the weight from increasing, and also preventing the raw material in the powder state from being discharged to the outside and damaging the health of the worker in advance. .

After all the raw materials to be mixed are put into the container 1, the PLC 100 moves the solenoid valve SV18 (SV19) to move the container 1 on the rail 5 to the belt conveyor 24. By driving and applying air pressure, the mining plate 18 is moved along the base plate 17 to move to the top of the container 1. In addition, the plate 20 is lowered by the operation of the cylinder 21 by driving the solenoid valve SV20 to apply air pressure to the cylinder 21. At this time, the PLC 100 drives the solenoid valve SV17 so that air pressure is applied to the cylinder 23 so that the collectors 22a and 22b are lowered in the open state. The PLC 100 then operates the cylinders 23, 21 and the moving plate 18 in the reverse order described above to pick up the container 1 and move it to the top of the belt conveyor 24 and then to the belt conveyor 24. It will be seated on top of it.

At this time, the moving distance of the moving plate 18 and the stopping position of the moving plate 18 moving on the base plate 17 are connected to a plurality of photosensors PS3 and PS4 installed on the side of the moving plate 18. The position data of the moving plate 18 detected by the controller 100 is recognized.

Accordingly, the container 1 seated on the upper part of the belt conveyor 24 is moved along the rounding conveyor 27, the belt conveyor 25, the rounding conveyor 28, and the belt conveyor 26 to the front end of the mixing container. Lose. At this time, the position of the container (1) to be moved is by the photosensors installed on the side of the belt conveyor 24, the rounding conveyor 27, the belt conveyor 25, the rounding conveyor 28, the belt conveyor 26 Since it is sensed and applied to the PLC 100, the PLC 100 can recognize the position of the container 1 to be moved and prepare for the next operation, and also a wading belt conveyor installed in the movement path of the container 1 By the weight of the container 1 sensed by (29) it is possible to detect the weight of the container (1) in which all the raw material is put, and confirm whether the raw material is correctly input.

Preferably, when the raw material is not correctly input, the PLC 100 outputs a warning signal by driving the display means, which is not shown, to prevent further progress of the container containing the raw material.

Subsequently, when the container 1 containing the raw material is moved to the end point of the conveyor, that is, to the side of the mixing container, the PLC 100 can feed the raw material contained in the container 1 seated on the belt conveyor 26 to the mixing container. The solenoid valve SV2 and SV2 are driven to apply air pressure so that the mining plate 9 is moved along the base plate 8 to the upper portion of the container 1. The plate 11 is lowered by the operation of the cylinder 12 by driving the solenoid valve SV4 so that the air pressure is applied to the cylinder 12. At this time, the PLC 100 descends while the solenoid valve (not shown) is operated to supply air pressure to the cylinders (13a) and (13b) so that the operation sections (14a) and (14b) with pads (15a) and (15b) at their ends are opened. Be sure to

Subsequently, when the pads 15a and 15b, which are defective at the ends of the operation periods 14a and 14b by the operation of the cylinder 12, move to the side of the container 1, the cylinders 13a and 13b again. Press both sides of the container 1 by the pads 15a and 15b, and then operate the cylinder 12 by air pressure to operate the container 1, the plate 11 and the operation 14a and 14b. Let it rise.

When the ascending of the container 1 ends, the PLC 100 operates the solenoid valves SV2 and SV3 again so that the moving plate 9 is moved on the base plate 8 to contain the raw materials for mixing. ) Is placed on top of the mixing vessel. Then, the solenoid valve SV1 is driven to rotate the rotary cylinder 16 installed on one side of the pad 15b to pour the raw material contained in the container 1 into the mixing vessel.

The PLC 100 then continuously operates the solenoid valves SV2 and SV3 such that the moving plate 9 is continuously moved on the base plate 8 to the upper part of the starting point of the rail 5. Then, the cylinder 12 and the cylinders 13a and 13b are operated at the upper portion of the starting point of the rail 5 so that the container 1 containing no raw material is placed on the upper portion of the monorail transfer 3 seated on the rail 5. After mounting, the operation of the cylinder 12 causes the plate 11 to rise between the operation sections 14a and 14b having the pads 15a and 15b.

At this time, the moving distance of the moving plate 9 and the stop position of the moving plate 9 moving on the base plate 8 are detected by the photosensors PS1 and PS2 installed on the side of the moving plate 9. It is made under the control of the PLC (100) recognized the position data of the moving plate (9).

Accordingly, the raw materials to be mixed are introduced into the mixing vessel and proceed to the next step, and the container into which the raw materials are mixed is placed in the monorail transfer 3 again to the input mixing ratio of the PLC 100 having a computer function. Accordingly, the above operation is repeatedly performed.

As described above, the present invention takes out a randomly set amount of raw material from the storage hopper while gradually moving the mono rail transfer on which the balance scale is seated to the lower portion of the storage hopper, and puts it in a container seated on the upper portion of the mono rail transfer. By moving along the belt conveyor and the rounding conveyor, it can be added to the mixing container, so that different raw materials can be added in a predetermined amount, and a plurality of raw materials can be mixed by one system.

In particular, the balance scale seated on the upper part of the mono rail transfer is composed of a differential transformer to sense the weight of the raw material contained in the container and the container and to measure the amount of each raw material, thereby not only inputting the correct amount of raw material, but also the container. It is possible to measure and mix a more accurate amount of raw materials by filtering by using a chute and a powder filter so that powder raw materials not contained in the container are not contained in the container.
