Description

Technical Field

[0001] The present invention belongs to the field of material weight acquisition, and particularly relates to a control method for weighing raw materials in a silo. Background Art

[0002] In the detection of raw materials in the silo of a pharmaceutical glass furnace, the next place for the raw materials in the silo is the furnace. In order to ensure the uninterrupted supply of raw materials for the furnace production, it is necessary to take goods from the silo of raw materials in real time to ensure the timely and sufficient supply of raw materials. In order to ensure the reasonable and efficient operation of the furnace, it is necessary to monitor the quality of the raw materials. Therefore, each time the raw materials are poured, quality control is required. Currently, most in the industry use manual detection methods, which are inefficient. There are also simple monitoring programs for automatic detection, but the handling of emergencies is not timely.

[0003] Therefore, it is necessary to design a control method for weighing raw materials in a silo to solve the above problems, which greatly reduces manual intervention and improves work efficiency.

[0004] For example, a Chinese patent document discloses a weighing control method, device and material weighing system [Patent Application No.: CN201711342656.1]. The weighing control method includes: storing weighing experience data of multiple weighing sensors for weighing materials; for the current weighing process, determining whether a weighing sensor fails; in the case of a weighing sensor failure, predicting the expected weight detection value of the failed weighing sensor in the current weighing process according to the weighing experience data; and combining the expected weight detection value with the current weight detection value of the weighing sensors without failure to determine the weight of the materials in the current weighing process. Summary of the Invention

[0005] The object of the present invention is to provide a control method for weighing raw materials in a silo for the above problems.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A control method for weighing raw materials in a silo, wherein a management system is connected to a weighing module collector, and the weighing module collector feeds back weight information to the management system in real time;

[0008] Step 1: Before the first run, the management system determines whether the tare weight is completed and the maximum load capacity is set;

[0009] Step 1.1: If it is determined in Step 1 that the tare weight is not completed and the maximum load capacity is not set, the human-machine interaction interface of the management system automatically pops up a setting interface for the staff to select;

[0010] Step 1.2: Select the peeling operation, place the carrier on the weighing module, record the weight G0 of the carrier, and clear the weighing data;

[0011] Step 1.3: Select to set the maximum load capacity and set the maximum load capacity to G1;

[0012] Step 2: After completing Step 1.2 and Step 1.3, exit the human-machine interaction interface. At this time, the management system determines that the peeling and setting of the maximum load capacity are completed, and proceeds to the weighing step.

[0013] In the above control method for weighing raw materials in a silo, after completing Step 2, proceed to the weighing step;

[0014] Step 3: Place the carrier on the weighing module. The weighing module re-collects the weight of the carrier and compares it with the recorded weight G0 of the carrier;

[0015] Step 4: If it is determined that the value is the same as G0, load the carrier with materials and collect the weight of the materials.

[0016] In the above control method for weighing raw materials in a silo, in Step 3, if the collected weight of the carrier is different from the value of G0, repeat Step 1.2. In this Step 1.2, the management system automatically performs and changes the record of the new weight G0 of the carrier. After performing Step 1.2, proceed to Step 4.

[0017] In the above control method for weighing raw materials in a silo, after performing Step 4;

[0018] Step 5: After the carrier is loaded with materials, compare the collected weight of the materials with G1;

[0019] Step 6: If the collected weight of the materials is less than or equal to G1, complete the loading and pick up the goods;

[0020] Step 7: Select to reload or end the operation. If reloading is selected, start from Step 3.

[0021] In the above control method for weighing raw materials in a silo, in Step 6, if the collected weight of the materials is greater than G1;

[0022] Step 6.1: Then upload it to the management system and issue a warning, and let the staff choose whether to continue.

[0023] In the above control method for weighing raw materials in a silo, Step 6.2: If it is selected not to continue, retrieve the materials. After retrieving the materials, proceed to Step 7.

[0024] In the above control method for weighing raw materials in a silo, in Step 6.1, if it is selected to continue, complete the loading and pick up the goods, and then proceed to Step 8;

[0025] Step 8: At this time, since the material weight exceeds G1, choose whether to reset the maximum load G1. If not, proceed to step 7.

[0026] In the above-mentioned control method for weighing raw materials in a silo, in step 8, if you choose to reset the maximum load capacity G1, proceed to step 1.3. In this step 1.3, the management system automatically performs and changes the record of the new maximum load capacity G1. After performing step 1.3, perform step 3 for reloading.

[0027] In the above-mentioned control method for weighing raw materials in a silo, all detection and execution elements and communications with peripheral devices are controlled by a PLC controller.

[0028] In the above-mentioned control method for weighing raw materials in a silo, when it is necessary to calibrate the weighing module, real-time online calibration can be performed through the human-computer interaction interface.

[0029] Compared with the prior art, the advantages of the present invention are:

[0030] The weight of materials is monitored in real time through system detection, and in case of emergencies, timely processing or warnings can be issued to remind staff, which greatly reduces manual intervention and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In Step 6.1, if the choice is to continue, complete the loading and pick up the goods, and then proceed to Step 8;

[0052] Step 8: At this time, since the weight of the materials exceeds G1, choose whether to reset the maximum load capacity G1. If not, proceed to Step 7.

[0053] In Step 8, if the choice is to reset the maximum load capacity G1, proceed to Step 1.3. In this Step 1.3, the management system automatically performs and changes the recorded new maximum load capacity G1. After performing Step 1.3, proceed to Step 3 for reloading.

[0054] All detection, execution elements and communication with peripheral devices are controlled by the PLC controller.

[0055] When the weighing module needs to be calibrated, real-time online calibration can be performed through the human-computer interaction interface.
