Difficult problems of dynamic checkweigher in production line
With the continuous improvement of industrial control automation, more and more processing plants have transformed from the original traditional manpower removal of checkweighing to data IoT technology automation plants. For automated technology production lines in fields such as food, pharmaceuticals, freight logistics, etc., dynamic checkweighers must be run efficiently and accurately every day. In order to ensure the delivery of large quantities of goods with net weights up to standard, it is necessary to frequently check checkweighers when operating. The difficult problems of the checkweigher are dealt with quickly. The following will tell everyone about the difficult problems of the dynamic checkweigher: Difficult problems of the dynamic checkweigher in the production line 1. No information is displayed on the touch screen of the checkweigher machine 1. Poor contact of the switching power supply 2. The fuse wire in the main box is burned out. 3. The mobile phone charging cable is loose or dropped. 2. The checkweigher touch screen displays no information. The data information vibrates greatly and fluctuates abnormally. 1. The screw of the checkweigher pedestal is loose 2. The sensor suffers significant impacts, such as central air-conditioning wind, cyclones, etc. 3. Road shaking, vibration, such as the influence of peripheral equipment rotation, car experience, etc. 4. The conveyor belt suffers from viscous objects. 5. The sensor base has dirt deposits or jams. 6. The filter index is set too small, the desktop display of the checkweigher is always zero 1. The object is light, and the net weight falls within the zero range. It should be handled according to the zero range again. 2. The machinery and equipment are found to be zero at this time. Adjust the automatic zero-tracking new item in the system software calibration options to deal with 3. The sensor mobile phone charging line is loose, and the contact is bad. 4. The page data information display information appears abnormal when the checkweigher is operating 1. Appears The reason for the deviation is very large, and the scale must be re-calibrated. 2. The product number is incorrectly selected. You should click to convert the product again and select the matching product number of the supporting facilities. 3. The working temperature exceeds the range of the sensor in all normal working conditions. 4. The sensor electronic device is embrittled or deformed. 5. The automatic program flow cannot be started when the checkweigher machine is in operation. 1. First check whether the feeding cylinder is turned off. When the cylinder is turned off, whether the position sensor is loose or not, the position sensor in time is actually dry. The reed power switch depends on the ring-shaped permanent magnet material in the cylinder to complete the closing and opening. 2. When the sensor position is wrong, the permanent magnet material in the cylinder becomes weaker, which will cause the data signal to be uncontrollable, and the automatic program will not start. . When the adjustment sensor fails, emergency treatment can be done: connect the sensor output line, which does not harm the application. VI. problem check. There are five LED lights on the dashboard of the computer motherboard to indicate the operating status, as shown in the figure: LED1 : Touch screen communication indicator LED2: Customer RS485 communication indicator LED3: Soft starter communication indicator LED4: AD abnormal indicator LED5: indicator In addition to the above 6 difficult problems of checkweighing scales, also consider the external connection Whether the equipment is problem-free can ensure the high-efficiency operation of all production lines, and the high-precision checkweigher machinery and equipment, showing the technical and professional checkweigher after-sales service technical explanation service items, make customers more at ease.
