weight Measuring part (600)

In the present invention, the weight measuring unit 600 is composed of a measuring member 620 and a pressing member 640. The measurement member 620 inputs the measured weight of the hellet to the control unit 700 and may include a balance, an electronic balance, a weight sensor, a load cell, or the like. In addition, a device in which the rod supported by the spring descends to come into contact with the measuring member 620 and then returns to its original position may be used if a load equal to or greater than a certain level is applied to the measuring member 620.

The pushing member 640 includes a center shaft 642 having both ends rotatably mounted on the side frame, a linkage 660 connected to the center shaft, a free end 644, and a presser foot 646 attached to the free end And the pressing member is mounted on the upper surface of the measuring member.

When the pellet loaded on the conveyor belt 420 presses the connecting rod 660 during movement, the weight measuring part 600 having such a configuration moves the free end 644 downward about the center shaft 642, (646) pushes the measuring member (620) so that the weight of the pellet is measured or sensed.

On the other hand, reference numeral 662 denotes a hole, which reduces the weight of the connecting rod and allows the weight to be accurately measured.

The output unit 740 may output a motor abnormality, a conveyor deflection or a lack of pellets through a panel, Method, and the like.

The control unit 700 basically controls the driving motor 520 by comparing the measured value inputted from the weight measuring unit 600 with a reference value inputted previously.

If the measured value is larger than the reference value, the control unit slows down the driving motor. That is, this state slows down the pellet feed rate of the pellet because the pellet can be excessively injected into the ringing machine 20.

Conversely, if the measured value is too low, the speed of the drive motor may be increased.

In another embodiment of the present invention, the dosage may be adjusted according to the season. In other words, in consideration of the fact that the state of the ripping machine and the frying temperature are changed during the summer and winter, the amount of the input is stored in the CPU, and the drive motor can be controlled using this database. In addition, the CPU of the present invention can calculate the feed rate in accordance with the conveying speed of the conveyor and the time, and calculate the average value to measure the production amount.

Detection sensor 720 and brush (800)

The detection sensor 720 is installed on both sides or one side of the conveyor belt 420. When the conveyor belt is pushed to the left or right side during pellet conveyance, .

In other words, the conveyor belt 420 may be deviated to one side due to mechanical vibration or external force during rotation. At this time, when the detection sensor 4720 installed on the side of the conveyor belt detects this and inputs the signal to the control unit 700, the control unit 700 recognizes and adjusts to the operator in the form of voice, character output or lamp lighting, It is possible to prevent the second failure of the shaft motor or other components and to prevent the supply amount from varying with the displacement.

Further, the present invention is also equipped with a sensor in the supply hopper and the drive motor so that the motor is abnormal or the supplementary signal of the pellet is output.

The brush 800 is fixed to a supporting frame and the sole portion 820 is brought into close contact with the conveyor belt 4520 to remove the pellets adhered to the conveyor belt during pellet conveyance.

Hereinafter, the operation of the present invention will be described.

The quantitative dosing apparatus 100 of the present invention starts by injecting pellets into the feed hopper 300. When the operator presses the operation button, the driving motor 520 operates to rotate the conveyor belt 420, and the conveyor belt 420 feeds the pellets injected from the supply hopper 300.

At this time, when the pellet reaches the weight measuring unit 600, the free end 644 and the pressure plate 646 descend by the weight, and the weight is measured by pressing the measuring member 620, (700) and compared with a preset reference value.

In this case, if the compared value is large, the control unit controls the drive motor to slow the moving speed of the conveyor belt. Conversely, if the comparison value is small, the speed of the driving motor can be increased.

As described above, the present invention is equipped with a weight measuring unit so that a predetermined amount of pellets is put into a picking machine.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken in limiting the scope of the present invention It will be understood by those skilled in the art that various changes, modifications, and alterations can be made therein by those skilled in the art to which the present invention belongs.
