Description

Technical Field

[0001] The invention relates to textile machinery technology, in particular to a textile shaping device with meter weight detection and a meter weight detection method technology. Background Art

[0002] In the textile shaping process, the measurement of fabric weight (grams per meter) plays an important role in the cost and production quantity of the product. The traditional method of measuring fabric weight is to manually measure the length of the fabric and weigh it. Manual operation is time-consuming and labor-intensive, and the error of fabric weight detection is large. It cannot be tested continuously, which easily leads to waste of raw materials and large deviation in production quantity. Summary of the invention

[0003] In view of the defects existing in the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a textile shaping device with meter weight detection and a meter weight detection method which can detect the meter weight of fabric and has a small meter weight detection error.

[0004] In order to solve the above technical problems, the present invention provides a textile shaping device with meter weight detection, comprising a frame and a shaping oven for drying fabrics; the frame is provided with a fabric conveyor chain for conveying fabrics, the shaping oven is provided with a heater for heating its inner cavity, the fabric conveyor chain passes through the inner cavity of the shaping oven from left to right, and the front and rear side edges of the fabric conveyor chain are provided with shaping needle plates for fixing fabrics, characterized in that:

[0005] The right end of the fabric conveyor chain is provided with a tail frame, on which a cloth-moving seat capable of sliding left and right is provided, and a cloth-moving guide rail for guiding the cloth-moving seat to slide left and right is provided, and the tail frame is provided with a plurality of flat cloth-guide rollers, wherein the first cloth-guide roller from the right is located directly above the cloth-moving guide rail;

[0006] Two horizontal cloth-moving rods are fixed on the cloth-moving seat, the two cloth-moving rods are arranged in parallel, and a gap is left between the two cloth-moving rods for the fabric to pass through, and an electronic scale for weighing is arranged directly below the cloth-moving guide rail;

[0007] A monitoring terminal is provided on the frame, a first photoelectric sensor and a second photoelectric sensor are provided on the left side of the frame, and a third photoelectric sensor is provided on the tail frame, wherein the first photoelectric sensor is used to detect the shaping needle plate located at the front or rear edge of the fabric conveyor chain, the second photoelectric sensor is used to detect the fabric on the fabric conveyor chain, and the third photoelectric sensor is used to detect the sliding times of the cloth-moving seat, the first photoelectric sensor, the second photoelectric sensor, and the third photoelectric sensor are respectively connected to the data acquisition port of the monitoring terminal, and the electronic scale is connected to the monitoring terminal via a serial communication cable.

[0008] The method for detecting the weight in grams of a textile shaping device with a weight in grams detection provided by the present invention is characterized in that:

[0009] When the second photoelectric sensor detects the fabric on the fabric conveyor chain, it sends a counting enable signal to the monitoring terminal, otherwise it sends a counting stop signal to the monitoring terminal;

[0010] When the monitoring terminal receives the counting stop signal, it stops counting the shaping needle plates. When the monitoring terminal receives the counting enable signal, it counts the number of shaping needle plates passing the position where the first photoelectric sensor is located through the first photoelectric sensor.

[0011] The monitoring terminal implements segmented detection on the shaped fabric through the third photoelectric sensor.

[0012] The calculation formula of the segmented weight in grams is: F=G÷M, where F is the segmented weight in grams in grams during the segmented detection period, G is the weight of the shaped fabric falling on the electronic scale during the segmented detection period detected by the monitoring terminal through the electronic scale, and M is the length of the shaped fabric falling on the electronic scale during the segmented detection period;

[0013] Among them, M = k × A, k is the count value of the shaping needle plate within the segmented detection time period, and A is the distance between the center lines of adjacent shaping needle plates.

[0014] The textile shaping device with meter-gram weight detection and the meter-gram weight detection method provided by the present invention use a photoelectric sensor to count the shaping needle plate and the cloth-displacing seat to calculate the total length and segment length of the fabric, and then combine the weighing value of the electronic scale to conveniently calculate the meter-gram weight of the shaped fabric, and the meter-gram weight detection error is small.

[0018] The right end of the fabric conveyor chain 4 is provided with a tail frame 8, on which a cloth-moving seat capable of sliding left and right is provided, and a cloth-moving guide rail 10 for guiding the cloth-moving seat to slide left and right is provided, and the tail frame 8 is provided with a plurality of flat cloth-moving rollers 14, wherein the first cloth-moving roller 14 from the right is located directly above the cloth-moving guide rail 10;

[0019] Two horizontal cloth-moving rods 11 are fixed on the cloth-moving seat. The two cloth-moving rods 11 are arranged in parallel, and a gap is left between the two cloth-moving rods 11 for the fabric 12 to pass through. An electronic scale 9 for weighing is provided directly below the cloth-moving guide rail 10.

[0020] A monitoring terminal 7 is provided on the frame, a first photoelectric sensor 1 and a second photoelectric sensor 2 are provided on the left part of the frame, and a third photoelectric sensor 3 is provided on the tail frame, wherein the first photoelectric sensor 1 is used to detect the shaping needle plate 6 located on the front or rear edge of the fabric conveyor chain 4, the second photoelectric sensor 2 is used to detect the fabric on the fabric conveyor chain 4, and the third photoelectric sensor 3 is used to detect the sliding times of the cloth-moving seat, the first photoelectric sensor 1, the second photoelectric sensor 2, and the third photoelectric sensor 3 are respectively connected to the data acquisition port of the monitoring terminal 7, and the electronic scale 9 is connected to the monitoring terminal 7 via a serial communication cable.

[0021] The embodiment of the present invention is used for textile shaping operation, and can detect the weight of fabric in grams per meter during the shaping operation. The working method is as follows:

[0022] A trolley 13 for loading shaped fabrics is placed on the electronic scale 9. Both sides of the fabric 12 are fixed by the shaping needle plates 6 on the fabric conveyor chain 4 and are conveyed from left to right through the fabric conveyor chain 4. During this process, the fabric first enters the shaping oven 5 for drying and shaping, and then is conveyed to the right end of the fabric conveyor chain 4. Then, the fabric is guided by the guide roller 14 on the tail frame 8, bypasses the first guide roller 14 from the right, passes through the gap between the two manipulator rods 11, and then falls onto the trolley 13. During this process, the manipulator seat slides back and forth left and right along the manipulator guide rail 10, so that the shaped fabric that falls on the trolley 13 can be repeatedly stacked left and right.

[0023] When the fabric conveyor chain 4 conveys the fabric 12 from left to right, there is a gap between the adjacent shaping needle plates 6 on the left and right, so that the first photoelectric sensor 1 can count the shaping needle plates 6 through the gap between the adjacent shaping needle plates 6. Each time the first photoelectric sensor 1 detects the gap between the adjacent shaping needle plates 6, it sends a counting signal to the monitoring terminal 7.

[0024] When the second photoelectric sensor 2 detects the fabric on the fabric conveyor chain 4, it sends a counting enable signal to the monitoring terminal 7, otherwise it sends a counting stop signal to the monitoring terminal 7;

[0025] When the monitoring terminal 7 receives the counting stop signal, it stops counting the shaping needle plates 6. When the monitoring terminal 7 receives the counting enable signal, it counts the number of shaping needle plates 6 passing the position of the first photoelectric sensor 1 through the first photoelectric sensor 1.

[0026] The monitoring terminal 7 implements segmented detection on the shaped fabric through the third photoelectric sensor 3. The segmented detection method is as follows: the monitoring terminal counts the number of times the cloth-placing seat passes the position of the third photoelectric sensor from zero through the third photoelectric sensor, and when the count value reaches a preset segmented number threshold, the length of time it takes to count the count value from zero to the segmented number threshold is defined as a segmented detection time period, and the segmented meter-gram weight of the segmented detection time period is calculated, and then the next segmented detection is implemented on the shaped fabric;

[0027] The calculation formula of the segmented weight in grams is: F=G÷M, where F is the segmented weight in grams in grams during the segmented detection time period, G is the weighing value of the shaped fabric falling on the electronic scale (that is, falling on the cart 13) during the segmented detection time period detected by the monitoring terminal through the electronic scale 9, and M is the length of the shaped fabric falling on the electronic scale during the segmented detection time period;

[0028] Among them, M = k × A, k is the count value of the shaping needle plate within the segmented detection time period, and A is the distance between the center lines of adjacent shaping needle plates.
