Polyester filament single filament cake fixed weight batch weighing device and weighing method thereof

Abstract

The invention discloses a polyester filament single filament cake fixed weight batch weighing device comprising conveying belts used for conveying a filament trolley. There are two conveying belts which are arranged in parallel. The conveying belts are driven by a conveying motor. The input end and the output end of the conveying belts are respectively provided with an inlet inductor and an outlet induction switch. The external side of the conveying belts is also provided with filament holding supports, filament holding support guide rails, a horizontal moving cylinder which drives the filament holding supports to horizontally slide on the filament holding support guide rails and an elevating cylinder which drives the filament holding supports to vertically move on the filament holding support guide rails. The filament holding supports are provided with filament holding rods which are matched with the filament cakes of the filament trolley. The number of the filament holding rods on each filament holding support is not less than the number of the filament cakes of one side of the filament trolley. Each filament holding rod is provided with an electronic scale used for weighing the filament cakes and a weighing timer. According to the polyester filament single filament cake fixed weight batch weighing device, the whole operation can be completed by one person, and the enterprise of the same scale of production and the same position can save 4-8 persons in comparison with conventional sampling monitoring so as to be time-saving and labor-saving and high in efficiency.

Description

Technical field: [0001] The invention is applicable to the field of polyester spinning production, and is used to monitor and control the fixed weight (design weight) of a given item to prevent it from exceeding or falling below the allowable standard range. It is a batch weighing of a single filament cake of polyester filament Device and its weighing method. Background technique: [0002] At present, in the polyester filament production industry, due to the characteristics of the industry chain, the products on the production line are generally transported by wire cars, and each wire car can hold 24-48 silk cakes, and the filaments are AAA or AA grade ( High-quality products) silk cakes are all required to be fixed in length and weight, and the fixed length can generally be accurately controlled by the mechanical speed and time of the production equipment, but the weight of the silk cake is controlled by a mechanical metering pump, and there are several hidden dangers: 1. ...

Problems solved by technology

[0002] At present, in the polyester filament production industry, due to the characteristics of the industry chain, the products on the production line are generally transported by wire cars, and each wire car can hold 24-48 silk cakes, and the filaments are AAA or AA grade ( High-quality products) silk cakes are all required to be fixed in length and weight, and the fixed length can generally be accurately controlled by the mechanical speed and time of the production equipment, but the weight of the silk cake is controlled by a mechanical metering pump, and there are several hidden dangers: 1. When the mechanical metering pump is used in a high temperature environment (about 290°C) for a long time, it will wear to a certain extent, the measurement error will be too large, and the fixed weight of the silk cake will be biased; 2. The viscosity fluctuation of the spinning melt of the filament will also cause the fixed weight 3. Other abnormal fluctuations in production lead to deviations in the fixed weight of the silk cake

The deviation of the fixed weight of the silk cake will lead to the thickness of the filament fiber, which will cause quality problems such as thickness and uneven surface of the subsequent fabric.

Generally, this kind of lightness and heavyness cannot be distinguished by human eyes, and must be detected by sophisticated weighing instruments, while the traditional weight monitoring of silk cakes is done manually, and the output of polyester filament enterprises in the polyester industry is relatively low. High, based on an annual output of 200,000 tons, the number of silk cakes in 24 hours a day is about 40,000, so the production efficiency of relying on manual weighing is very low, and the surface of the silk cakes is easily damaged during manual operation, which affects product quality
