Description

Technical Field

[0001] The present invention relates to the technical field of intelligent fabric detection, and in particular to a multi-directional automatic control fabric detection device and a detection method. Background Art

[0002] During the production and processing of clothing, it is necessary to perform performance tests on the fabrics used to obtain the limit data of various performances of the clothing, so as to provide experimental data for the subsequent fabric production process. Therefore, testing devices for clothing fabric performance are developed accordingly.

[0003] At present, most of the testing devices for the performance of clothing fabrics on the market are mainly unable to test the pulling properties and friction resistance of the fabrics, or they can be provided with testing devices for the pulling properties and friction resistance, but they require multiple energy-consuming driving forces to work, resulting in a large amount of energy consumption. In addition, during the process of pulling the clothing fabrics, the clamping force of the clamping plate cannot increase with the pulling distance, making the fabrics easy to detach.

[0004] Nowadays, more and more equipment for fabric performance testing is being developed. For example, Chinese patent invention patent CN112945783A discloses an energy-saving and environmentally friendly clothing fabric pulling and friction resistance testing device, including a frame, a motor assembly is connected to the rear side of the frame, a first movement chamber is fixedly connected to the right side of the first connecting rod, a clamping plate is slidably connected to the inner side of the first movement plate, an operating rod is arranged on the front side of the clamping plate, the upper and lower sides of the first sliding rod are fixedly connected to the first guide rod, and the right side of the first rotating shaft is fixedly connected to the friction roller. The energy-saving and environmentally friendly clothing fabric pulling and friction resistance testing device drives the first connecting rod to slide back and forth, so that the clamping plate drives the fabric to pull back and forth, and at the same time, the first rotating shaft drives the friction roller to rotate synchronously, so that the first rotating shaft and the fabric rub against each other, and only one driving force that consumes energy is required. This structure can achieve the effect of pulling and friction resistance testing and energy saving and environmental protection.

[0005] However, the above-mentioned fabric detection device still has the following defects: 1. It can only detect a fixed section of fabric, and cannot perform online detection during the fabric conveying process; 2. It still uses the friction between the rotating shaft and the fabric for detection, that is, it can only detect one side of the fabric, and cannot perform double-sided detection; 3. The detection of pulling performance and friction performance is performed separately, and it is impossible to simulate the pulling and friction performance detection of the fabric at the same time; 4. It is impossible to detect the fabric in multiple directions at the same time.

In addition, features described in some examples may be combined in other examples.

[0028] Example 1: Please refer to Figure 1 , which is only one embodiment of the present invention, is a multi-directional automatic control fabric detection device, comprising a first transmission roller 1, a second transmission roller 2, a first guide roller 51 and a second guide roller 52; so that the fabric 6 is guided by the first guide roller 51, then passes through the first transmission roller 1 and the second transmission roller 2 in sequence, and finally is transmitted out through the second guide roller 52; In the present invention, the roller diameters of the first transfer roller 1 and the second transfer roller 2 are the same, the two transfer rollers are arranged in parallel, and the first guide roller 51 and the second guide roller 52 are both located on one side between the first transfer roller 1 and the second transfer roller 2, so that the fabric cloth 6 has a larger area to contact the first transfer roller 1 and the second transfer roller 2, and the first transfer roller 1 and the second transfer roller 2 are both in contact with the same side of the fabric cloth 1, hereinafter referred to as the inner side of the fabric cloth.

[0029] Of course, the direct transmission power of the fabric cloth comes from the first guide roller 51 and / or the second guide roller 52, and then the inner side of the fabric cloth can be pulled and rubbed at the first transmission roller 1 and the second transmission roller 2.

[0031] It should be noted that among the plurality of first friction rollers 31, two adjacent first friction rollers 31 are not directly connected, so that the rotation of the first friction rollers 31 will not be directly affected, and the plurality of first friction rollers 31 can rub against the outer side of the fabric 6 in the same direction and at the same speed; On the contrary, two adjacent second friction rollers 41 are meshed and connected, so that the two adjacent second friction rollers 41 rotate in opposite directions to rub the outer side of the fabric cloth 6 .

[0032] In this way, the outer side of the fabric cloth 6 is pulled and rubbed at the first friction roller 31 and the second friction roller 41 .

[0033] Finally, a plurality of detection probes 7 are provided at the place where the fabric cloth 6 is transmitted. In fact, the detection probes 7 include a first probe provided in front of the first guide roller 51 for detecting the side of the fabric cloth close to the first transmission roller, a second probe provided between the first guide roller 51 and the first transmission roller 1 for detecting the side of the fabric cloth away from the first transmission roller, a third probe provided between the first transmission roller 1 and the second transmission roller 2 for detecting the side of the fabric cloth away from the first transmission roller, a fourth probe provided between the first transmission roller 1 and the second transmission roller 2 for detecting the side of the fabric cloth close to the first transmission roller, a fifth probe provided between the second guide roller 52 and the second transmission roller 2 for detecting the side of the fabric cloth away from the second transmission roller, and a sixth probe provided behind the second guide roller 52 for detecting the side of the fabric cloth close to the second transmission roller.

[0034] That is, the first probe, the fourth probe and the sixth probe acquire images of the inner side of the fabric; The second probe, the third probe and the fifth probe acquire images of the outer side of the fabric cloth.

[0035] In summary, the present invention is directly arranged on the conveying line of the fabric cloth, and the fabric cloth is transmitted in the form of a cloth belt in the structure of the present invention. The transmission power of the fabric cloth comes from the guide roller, the inner side of the fabric cloth is pulled and rubbed at the transmission roller, and the outer side of the fabric cloth is pulled and rubbed at the friction roller; and the fabric cloth can be detected on both sides online during the transmission process, and the transmission, pulling and rubbing are all carried out synchronously, and multi-directional detection can be performed on both sides of the fabric.

[0036] When the present invention is used, the steps are: Fabric pre-arrangement: after the front end of the fabric is guided into the first guide roller, it passes through the first transmission roller and the second transmission roller in sequence, and is transmitted out through the second guide roller; Probe turned on; turn on the detection probe where the fabric passes through, and ensure that the detection probe obtains the fabric image; Double-sided contact; the first friction roller of the first roller group contacts the side of the fabric away from the first transmission roller; the second friction roller of the second roller group contacts the side of the fabric away from the second transmission roller; Fabric transmission; the first guide roller and the second guide roller drive the fabric to be transmitted; Acquire data; the detection probe acquires the fabric image at a predetermined interval and uploads it, and the computer performs image recognition and analysis.

[0037] The invention discloses a multi-directional automatically controlled fabric detection device, which can perform online detection on both sides of the fabric during fabric transmission, and utilize the force transmitted by the fabric to simultaneously perform fabric performance detection of pulling and friction, and the fabric is automatically detected in multiple directions during detection, with high detection accuracy and low energy consumption.

[0038] Example 2: See Figure 1 , 2 , is only one of the embodiments of the present invention. On the basis of Embodiment 1, in a multi-directional automatic control fabric detection device of the present invention, the first guide roller 51 is connected to a third drive motor; the second guide roller 52 is connected to a fourth drive motor, so that the first guide roller 51 and the second guide roller 52 have the same rotation direction and the same rotation angular velocity.

[0039] In another case, the third driving motor of the first guide roller 51 and the fourth driving motor of the second guide roller 52 are the same driving source, or the first guide roller 51 and the second guide roller 52 are linked by a belt.

[0040] It is only necessary to ensure that the fabric cloth is transported at a constant speed under the traction of the first guide roller 51 and / or the second guide roller 52 .

[0041] In the present invention, the first guide roller 51 and the second guide roller 52 are both rubber rollers, which can increase friction, effectively guide the transmission of the fabric, and prevent the fabric from slipping during friction and pulling detection.

[0042] Embodiment 3: Still refer to Figure 1 , 2 , is only one embodiment of the present invention. On the basis of any of the above embodiments, in a multi-directional automatic control fabric detection device of the present invention, friction protrusions are provided on the outer sides of the first friction roller 31 and the second friction roller 41; the friction protrusions are used to perform friction detection on the outer side of the fabric.

[0043] The first transmission roller 1 and the second transmission roller 2 are both metal rollers, and the outer sides of the first transmission roller 1 and the second transmission roller 2 are both provided with friction patterns, and the inner side of the fabric cloth is rubbed by the friction patterns.

[0044] As one of the embodiments of the present invention, the first transmission roller 1 is connected to a first driving motor, so that there is a speed difference between the rotation of the first transmission roller 1 and the transmission of the fabric cloth 6, so that the friction pattern of the first transmission roller 1 can effectively rub the inner side of the fabric cloth.

[0045] As one of the embodiments of the present invention, the second transmission roller 2 is connected to a second driving motor; so that there is a speed difference between the rotation of the second transmission roller 2 and the transmission of the fabric cloth 6, and there is a speed difference between the rotation of the second transmission roller 2 and the rotation of the first transmission roller 1.

[0046] In this way, the friction pattern of the second transmission roller 2 can effectively rub the inner side of the fabric cloth; at the same time, there is a speed difference between the rotation of the second transmission roller 2 and the rotation of the first transmission roller 1, so that there is a pulling force on the fabric cloth when it passes through the guide roller, the first transmission roller 1 and the second transmission roller 2, so that the speed difference between the first transmission roller 1 and the second transmission roller 2 can rub and pull the inner side of the fabric cloth at the same time, so that when the first probe, the fourth probe and the sixth probe acquire images of the inner side of the fabric cloth, at least one can acquire the image of the inner side of the fabric cloth after friction and pulling at the same time, so as to detect and analyze the inner side of the fabric cloth.

[0047] In the present invention, the number of the first friction rollers 31 is at least two, and two adjacent first friction rollers 31 are connected by a connecting roller 32, the first friction roller 31 is meshed and connected with the connecting roller 32, and the connecting roller 32 does not contact the fabric cloth 6; all the first friction rollers 31 have the same specifications, and all the connecting rollers 32 have the same specifications, so that all the first friction rollers 31 can rotate synchronously at the same speed to rub the outer side of the fabric cloth; Furthermore, all the second friction rollers 41 have the same specifications, so that the adjacent second friction rollers 41 rotate in opposite directions at the same speed to rub and pull the outer side of the fabric; In this way, when the second probe, the third probe and the fifth probe acquire images of the outer side of the fabric, at least one of them can acquire images of the outer side of the fabric after friction and pulling, thereby detecting and analyzing the outer side of the fabric.

[0048] It should be noted that the number of the second friction rollers 41 is an odd number, so that the number of the second friction rollers 41 rotating in one direction is one more than the number of the second friction rollers 41 rotating in the opposite direction. In this way, the area of ​​the outer side of the entire fabric portion subjected to the friction force in one direction is a little larger, and generally, the number of the second friction rollers 41 in the same direction as the fabric transmission direction is one more.

[0049] As one of the embodiments of the present invention, one of the first friction rollers 31 is connected to a fifth driving motor, so that the first friction roller 31 is no longer passively rotated with the transmission of the fabric cloth, but can actively perform differential friction and pulling on the outer side of the fabric cloth.

[0050] In another case, one of the second friction rollers 41 is connected to the sixth drive motor, and the second friction roller 41 can also actively perform differential friction and pulling on the outer side of the fabric.

[0051] Embodiment 4: Still refer to Figure 1 , 2 , is only one embodiment of the present invention.

[0052] Similarly, the second roller group 4 further includes a second shaft frame 42, and the rotating shafts of the second friction rollers 41 are connected to the second shaft frame 42 through connecting bearings; the second shaft frame 42 is connected to a second adjusting rod for driving the second shaft frame 42 to approach or move away from the second transmission roller 2; That is, the first roller group 3 can be far away from the first transfer roller 1. After the fabric cloth is arranged and wound, the first roller group 3 is close to the first transfer roller 1, so that the first friction roller 31 contacts the outside of the fabric cloth.

[0053] Similarly, the second roller set 4 can be away from the second transfer roller 2. After the fabric cloth is arranged and wound, the second roller set 4 is close to the second transfer roller 2, so that the second friction roller 41 contacts the outside of the fabric cloth.
