The embodiment also provides a counterweight sorting method, which is applied to the counterweight sorting system, and the method comprises the following steps:
s1, obtaining the weight of the material in the transmission process, which comprises: recording the weight of the container 1, acquiring the weighing data of the container 1 for containing the materials in a plurality of time periods at the end of the weighing time in the material conveying process, averaging to obtain the total weight of the materials and the container 1, and subtracting the weight of the container 1 from the total weight of the materials and the container 1 to obtain the weight of the materials.
Wherein, splendid attire container 1 itself has certain weight, need subtract the weight of splendid attire container 1 with the total weight of material and splendid attire container 1 for the accuracy of weighing and obtain the weight of material. Each container 1 on the counterweight sorting system has a constant number in the program. Before formal work of the container 1, the container runs for two circles in an idle load mode, the weight of the container 1 is recorded twice, an average value is calculated, and then the average value is written into a program storage space for permanent memory, so that the weight of the container 1 before formal weight collection is reduced, and the accurate weight of the material is obtained. In order to improve the sorting speed, the counterweight sorting system adopts a dynamic weighing mode, the weighing time of each container 1 is short (about 200 ms), and in order to make the weighing result correct as much as possible, data are acquired in 5 time periods at the end of the weighing time and the average value is calculated, so that the result is more accurate.
S2, analyzing and calculating the blanking position of the material;
and S3, controlling the rejecting mechanism 5 to lift each container 1 to enable the material to fall into the corresponding feed opening 6.
Wherein, the unloading position of analysis and calculation material includes:
setting the upper limit and the lower limit of a counterweight range as A and B, setting the weight of the minimum individual material as C, analyzing the existing material weight weighted by a feed opening 6 and the total mass of the current material and the located interval after the materials are weighed, and controlling a rejecting mechanism 5 to flip a container 1 to enable the materials to fall into the feed opening 6 if the existing material weight is in the interval [0, A-C ] or the interval [ B, A ]; if the material is in the interval (A-C, B) or the interval (A, infinity), the blanking port 6 stops blanking, the existing material weight of the next blanking port counterweight is analyzed, and the total mass after the current material and the interval in which the current material is located are added, so that a new round of judgment is carried out.
The interval (A-C, B) is an anti-locking interval, the existing material weight of the balance weight of the feed opening plus the total mass of the current material and once the balance weight enters the interval, the feed opening 6 is locked, and the minimum material weight is put into the interval and exceeds the upper limit A. Therefore, the interval is set to be an anti-locking interval, and materials cannot enter the interval. In addition, when the total mass sum of the materials meets the interval [0, A-C ], the materials are only simply removed, and when the total mass sum of the materials meets the interval [ B, A ], a full-blending mark is set while the materials are removed, and the full-blending mark controls the indicator light to be on, so that the total mass sum of the materials of the blanking port 6 can be taken away. Before the material is taken away, the full-matching mark can control other materials not to enter the feed opening 6 until the material is taken away, and the full-matching mark is cancelled.
The user needs to set a weight range to be sorted in advance, such as 500g +/-50 g of potatoes, so that the weight range is 450g-550g, the upper limit of the weight range is 550g, and the lower limit of the weight range is 450 g. Therefore, the total mass and the weight of the container 1 can be obtained after the materials pass through the weighing sensor 42, the position of the feed opening 6 suitable for the materials to fall is calculated through the PLC 8, and when the materials are transmitted to the corresponding position of the feed opening 6, the PLC 8 controls the rejecting mechanism 5 to act, so that the container 1 is overturned, and the materials fall to the correct feed opening 6. Assuming that the minimum weight of the potatoes is 150g, after the materials are weighed, judging the weight of the existing materials of the feed opening 6 plus the total mass of the current materials and the section where the existing materials are located, and controlling the removing mechanism 5 to turn over the container 1 to enable the materials to fall into the feed opening 6 if the existing materials are located in the section [0g, 400g ] or the section [450g, 550g ]; when the current time is within the interval (400g, 450g) or the interval (550g, infinity), the feeding of the feed opening 6 is stopped, and the PLC controller 8 analyzes the total mass sum of the materials at the next feed opening 6 to perform a new round of judgment. After the agricultural products at the feed opening 6 reach the set numerical value, the preset indicator lamp of the feed opening 6 is turned on until the agricultural products are taken away and the agricultural product taking-away signal is received, the indicator lamp is turned off, the balance weight sorting of a new round of agricultural products is continued, and the process is repeated. According to the invention, a plurality of feed openings 6 are set, each feed opening 6 operates independently and can be independently set to be sorting or counterweight, and the balance weight sorting efficiency is greatly improved.
The counterweight sorting method further comprises the step of calibrating the weighing mechanism 4, wherein the calibration is completed before the counterweight sorting system is formally operated, the calibration is divided into two steps, and the first step is to determine a 0-point value which is a numerical value when no object exists on the weighing mechanism 4. And in the second step, 100g of standard weight is put on the weighing mechanism 4, the test value is recorded, two points determine a straight line, and the weighing mechanism 4 can be accurately calibrated according to the standard weight and the 0-point value.
