Description

Technical Field

[0001] The invention belongs to the technical field of knitted socks production, and in particular relates to a device and method based on a knitted socks finished product weight detection system. Background Art

[0002] The current technology of knitted socks is quite mature. In order to pursue more beautiful socks or meet different needs, knitted socks are made of a variety of yarns. It is of great significance to accurately calculate the weight of various yarns for subsequent cost analysis and performance analysis. The traditional weighing method is just to weigh the yarn, which cannot directly reflect the weight of the finished socks. This requires manual weighing of the socks. If the sampling method is adopted, it will not only consume manpower, but also may not reflect the accurate data of this batch of socks. If the method of full inspection is adopted, it is undoubtedly a great waste of manpower.

[0003] The Chinese invention patent CN116972945A proposes an automatic weighing device and method for knitted socks yarn feeding. The invention describes the weighing and calculation method of the raw materials of the sock machine, and conducts an in-depth study of the calculation process. It does not test the produced products. The operator also needs to test the weight of the finished socks separately, and does not solve the problem of improving the yield of socks.

[0004] Chinese utility model patent CN211477342U is a finished product weight detection device for a hosiery machine. It solves the problem of electronic scale accuracy affected by the impact of socks outflow by analyzing the influence of errors caused by different yarn tensions on the finished product to a certain extent.

[0005] Chinese utility model patent CN21805170U discloses a collection device for a Lonati sock machine. The utility model patent weighs the socks in the collection device and compresses the weighed socks by squeezing. This operation affects the accuracy of the electronic weighing and causes a greater deviation in the detection of the finished socks. Summary of the invention

[0043] Figure 1 , Figure 5 , Figure 6 As shown, the method for detecting the weight of finished knitted socks includes the following steps:

[0044] Operate the knitting sock machine to make samples according to production requirements, make the pattern program based on the sample process sheet, configure the yarn required to produce the pattern, check and burn the sock machine, and officially start it after it works correctly;

[0045] By analyzing the product process, the operator manually transmits the yarn weight data of each type of yarn needed and the weight of a single sock finished product to the system according to the process sheet; the above collected data is used as the system initial value, and the system sets an error value for the yarn weight and an error value for the weight of a single sock finished product;

[0046] When the sock machine starts working, data is collected on the weight of each yarn used in a single sock during normal operation; data is collected on the weight of a single finished sock; and the product is tested by transmitting the collected data to the data processing module;

[0047] The weighing device transmits the collected data information to the data processing module of the sock machine, and compares the real-time data used in the production of each sock with the system initial value data. Through comparative analysis, the data processing module can determine whether the sock is qualified and record the detailed data of each sock production;

[0050] Production efficiency: the ratio of the number of qualified products in unit time to the total number of products produced. The production efficiency reflects the ratio of the normal working condition of this sock machine to the total working condition.

[0051] The yarn data collection device uses a yarn weighing module to measure the weight of the yarn fed into the sock machine when it is working, and the initial weight of a single yarn roll is measured as b 1， When a single sock is knitted, the weight of the yarn roll is measured as m1, and the weight of a certain roll of yarn consumed when producing a single sock is h1 = (m1-b1); when there are multiple yarn rolls to work, these yarn rolls are numbered 1, 2, 3...N, and the initial mass of each yarn roll is b1, b2, b3...b n ; When a single sock is knitted, the yarn weight is measured as m1, m2, m3…m n The consumption of yarn rolls for the production of any finished sock is h1, h2, h3…h n ; It is installed on the yarn frame behind the sock machine.

[0055] The finished product data acquisition device measures the weight of the socks made by the sock machine by the finished product weighing module. When there is no production, there is no finished socks output, and the measured value is w0=0. After the socks are processed by the sock machine, the finished socks are transported out of the sock machine outlet and enter the finished product weighing module. At this time, the finished product weighing module will record the data changes as w1, w2, w3...w n , the finished socks are numbered 1, 2, 3...N according to the production order, then the weight of any one of the finished socks is w n .

[0056] The finished product data collection device is a device that collects the socks coming out of the sock machine. By changing the production quantity of the finished socks, the value of the electronic weighing device below will change, and the data will be collected and transmitted to the next step.

[0057] The finished product collection module is installed below the sock outlet of the sock machine and is mainly composed of a suction cylinder, a collection port, an electronic scale, a weighing box, a suction motor and an opening motor; the collection port is installed above the weighing box, the opening motor is installed between the collection port and the weighing box, an electronic scale is installed at the lower part of the box, the internal opening is connected to the suction cylinder, the middle section of the suction cylinder is connected to the suction motor, and the other end is connected to the weighing outlet.

[0058] The data storage module records the data measured by the yarn data acquisition device and the finished product data acquisition device, and calculates the yarn weight H consumed by the sock machine when producing each finished sock through the calculation unit. n And the weight of each finished sock produced by the sock machine is w n .

[0059] Data storage, the data measured by the yarn data acquisition device and the finished product data acquisition device are saved through the internal memory, and according to the actual production needs, the data are imported into the database for storage.

[0060] The data processing module compares the data stored in the data storage unit. The operator can set the standard yarn weight and finished product weight range for a certain type of socks according to actual production needs. The data processing module compares the data information collected by the data storage module with the set value. If the group of data is within the error range allowed by the module, it continues to operate normally and the alarm light is green; if the group of data is not within the range allowed by the module, the operation module will judge it again. If it does not exceed the conditions set by the module, it will continue to operate and the alarm light will be yellow; if the group of data is not within the range allowed by the module, the operation module will judge it again. If it exceeds the conditions set by the module, the machine will stop working and the alarm light will be red.
