The multi-head microcomputer combination weighs
The working principle of multi-head microcomputer combination scale:
1.The product is in the cross-cutting bucket, vibrated by the main vibrating machine, so that the material is evenly distributed on the conical funnel to the linear vibrating plate.
2. The driving device, that is, the stepper motor works, the feed hopper opens, and the product falls into the weighing hopper. When the product in the weighing hopper does not reach the preset weight requirement, the product will be automatically replenished.
3. In the weighing hopper, the product generates a weight signal through the sensor, and then transmits it to the main board of the control device through the lead. The CPU on the main board reads and records the weight of each weighing hopper, and then calculates, analyzes, and combines. Select a multi-head microcomputer combination weighing hopper that is close to the target weight. When there is a signal to allow discharging, the CPU issues a command to start the driver to open the selected weighing hopper to unload the product into the sorting trough and enter the collection hopper. Directly into the vertical packaging machine.
AFC is an automatic control vibration tracking mode. The AFCT mode means that the number of combined buckets is used as the tracking item. The program automatically corrects all line amplitudes simultaneously to meet the requirements of the combination. The AFCI mode is based on the single bucket weight as the tracking mode, and its reset interval is executed once, which is to achieve a re-correction of the linear vibration machine amplitude. The AFC function is more suitable for materials with large volume and poor fluidity. In order to ensure accuracy, the speed can be appropriately reduced to achieve.
Compared with the general photoelectric detection, the combination of 3 generations of multi-head microcomputers researched by Compaq is said to realize the detection of the main vibration sensor. It is more sensitive than the general photoelectric detection, and also makes the information feedback more accurate, which is beneficial to the material transportation of the elevator.
Generally, the multi-head microcomputer combination is said to work in the workshop, and there are often power motor equipment running in the workshop to produce vibration on the ground. The human body generally cannot feel this vibration, but it will be sensed for the high-sensitivity multi-head microcomputer combination. The quantitative data is unstable. For this reason, the multi-head microcomputer combination weighs an additional vibration sensor in addition to the load cell, and removes the sensed vibration component from the load cell data to obtain reliable data.
