Example Embodiment
[0050] Example one
[0051] The feeding device group 1 is composed of two feeding devices. The conveying device is located under the feeding device. The sensor group 4 is composed of two weighing sensors. Each weighing sensor is located under the corresponding feeding device. Each weighing sensor is installed. On the fixed plate 22 of the conveying device 2. When the conveying device 2 steps by one station distance, there will be a material weighing container 3 set on a weighing sensor, and the supporting pallet 5 will evenly transfer the gravity of the material weighing container 3 to the weighing sensor; The control system can analyze whether there is a material weighing container 3 above and whether the added weight reaches the preset value by monitoring the weight on the load cell; when the first material weighing container 3 is transported to the first feeding device 11 Below the discharge port, the control system controls the first feeding device 11 for forward rotation an...
Example Embodiment
[0052] Example two
[0053] The feeding device group is composed of three feeding devices, namely the first feeding device 11, the second feeding device 12 and the third feeding device 13. The conveying device 2 is arranged under the feeding device, and the sensor group 4 is composed of two load cells. They are the second load cell 42 and the third load cell 43 respectively. The second load cell 42 is located below the second feeding device 12, and the third load cell 43 is located below the third feeding device 13, each The load cells are all installed on the fixed plate 22 of the conveying device 2. When the conveying device 2 steps by one station distance, there will be a material weighing container 3 set on a weighing sensor, and the supporting pallet 5 will evenly transfer the gravity of the material weighing container 3 to the weighing sensor; The control system can analyze whether there is a material weighing container 3 above and whether the added weight reaches the pres...
Example Embodiment
[0054] Example three
[0055] The feeding device group 1 is composed of three feeding devices, namely a first feeding device 11, a second feeding device 12, and a third feeding device 13; the sensor group 4 is composed of three sensors, respectively A first load cell corresponding to the position of the first feeding device 11, a second load cell 42 corresponding to the position of the second feeding device 12, and a third load cell 43 corresponding to the position of the third feeding device 13. The control system controls the conveying device 2 to step by one station distance at intervals. When the material weighing container 3 is conveyed to the position below the discharge port of the first feeding device 11, the control system controls the first feeding device 11 to rotate and discharge materials. The system detects the increased weight of the material weighing container 3 through the first weighing sensor. When the increased weight of the material weighing container 3 reach...
