Description

Technical Field

[0001] The present invention relates to the technical field of cloth detection, and in particular to a cloth monitoring static sampling device based on clamping of a clamping plate and a control method thereof. Background Art

[0002] Traditional fabric monitoring includes testing of defects, elasticity, stretchability and other properties, many of which are still done manually, with few automated testing methods. With the rapid advancement of science and technology, automated defect detection for textiles has also developed rapidly.

[0003] At present, fabric monitoring is carried out in a dynamic environment by continuously photographing and sampling with industrial cameras. Since the fabric is continuously transported under the traction of the transmission mechanism, it is impossible to provide a static sampling environment. It is not realistic to stop the machine for static sampling. However, when continuously photographing and sampling with industrial cameras, at the moment of taking pictures, the fabric being transported at this stage is a blind spot, which greatly affects the accuracy of fabric monitoring, and there are problems such as missed detection and low local detection accuracy. Moreover, the existing dynamic sampling environment for fabric monitoring has a complex transmission structure and poor stability. The static fabric is in a state of jitter and offset, and the sampling accuracy is not high, which naturally affects the subsequent fabric monitoring results.

[0004] Therefore, how to ensure that the cloth enters and exits the machine at a constant speed, has a simple structure, is easy to operate, and can build a static sampling environment for the cloth to provide the accuracy of the cloth monitoring data source is a problem that needs to be solved at present. Summary of the invention

The slideway can adjust the height up and down to change the fabric length of the short stop.

[0044] like Figure 1-Figure 11 The static sampling device for monitoring cloth based on clamping of the present invention comprises a cloth buffer mechanism 1, a cloth clamping mechanism 2 and a buffer damping mechanism 3 installed in a cloth monitoring sampling frame.

[0045] The cloth buffer mechanism 1 comprises a lower cloth inlet buffer unit and an upper cloth outlet buffer unit. The cloth inlet end of the lower cloth inlet buffer unit is used for introducing cloth conveyed by the cloth inlet guide roller 6, and the cloth outlet end of the upper cloth outlet buffer unit provides cloth introduction for the cloth outlet guide roller 4.

[0046] The cloth clamping mechanism 2 comprises a lower cloth clamping unit 201 and an upper cloth clamping unit 202 located on the same vertical plane. The cloth inlet end of the lower cloth clamping unit 201 introduces cloth from the inlet and outlet end of the lower cloth inlet buffer unit, and the cloth outlet end of the lower cloth clamping unit 201 provides cloth for the upper cloth outlet buffer unit.

[0047] The synchronous clamping between the lower cloth clamping unit 201 and the upper cloth clamping unit 202 realizes static sampling of the cloth in transmission, and at this time, the cloth buffer mechanism 1 is used to ensure that the cloth is transported at a uniform speed in and out.

[0048] The buffer damping mechanism 3 is located below the cloth buffer mechanism 1 and is used to unload the kinetic energy generated during the falling process of the cloth buffer mechanism 1 .

[0049] Preferably, the lower fabric clamping unit 201 and the upper fabric clamping unit 202 are synchronously clamped for static sampling, at which time the lower fabric inlet buffer unit and the upper fabric outlet buffer unit rise, the rising lower fabric inlet buffer unit absorbs the fabric, and the rising lower fabric inlet buffer unit releases the fabric, ensuring that the fabric is transported at a uniform speed in and out.

[0050] Preferably, the lower cloth-feeding buffer unit comprises a lower cloth-feeding guide roller 103, a lower cloth-feeding transmission guide roller 104 and a lower cloth-feeding outlet guide roller 105, and the upper cloth-outlet buffer unit comprises an upper cloth-outlet cloth-feeding guide roller 106, an upper cloth-outlet transmission guide roller 107 and an upper cloth-outlet outlet guide roller 108. The cloth delivered by the cloth-feeding guide roller 6 sequentially passes through the lower cloth-feeding guide roller 103, the lower cloth-feeding transmission guide roller 104 and the lower cloth-feeding outlet guide roller 105 to enter the lower cloth-clamping unit 201, and the cloth delivered by the upper cloth-clamping unit 202 sequentially passes through the upper cloth-outlet cloth-feeding guide roller 106, the upper cloth-outlet transmission guide roller 107 and the upper cloth-outlet outlet guide roller 108.

[0051] The lower fabric inlet transmission guide roller 104 and the upper fabric outlet transmission guide roller 107 are distributed in lower and upper fixed positions through the fabric buffer fixed seat 109. During the process of the lower fabric inlet transmission guide roller 104 and the upper fabric outlet transmission guide roller 107 being driven to rise by the fabric buffer fixed seat 109, the lower fabric clamping unit 201 and the upper fabric clamping unit 202 are synchronously clamped for static sampling; the lower fabric clamping unit 201 and the upper fabric clamping unit 202 are synchronously released, and the fabric buffer fixed seat 109 drives the lower fabric inlet transmission guide roller 104 and the lower fabric outlet guide roller 105 to fall freely, and unload the force through the cache damping mechanism 3.

[0052] The lower cloth clamping unit 201 comprises a lower cloth clamping guide roller 203, a lower left cloth clamping plate 204, and a lower right cloth clamping plate 205. The cloth conveyed by the lower cloth feeding and discharging guide roller 105 is transmitted to between the lower left cloth clamping plate 204 and the lower right cloth clamping plate 205 through the lower cloth clamping guide roller 203. A lower clamping control arm 206 is disposed above the lower left cloth clamping plate 204 and the lower right cloth clamping plate 205. The lower clamping control arm 206 controls the clamping or releasing of the cloth between the lower left cloth clamping plate 204 and the lower right cloth clamping plate 205.

[0053] The upper cloth clamping unit 202 includes an upper cloth clamping guide roller 207, an upper left cloth clamping plate 208, and an upper right cloth clamping plate 209. The cloth between the lower left cloth clamping plate 204 and the lower right cloth clamping plate 205 is transferred to between the upper left cloth clamping plate 208 and the upper right cloth clamping plate 209. An upper clamping control arm 210 is provided below the upper left cloth clamping plate 208 and the upper right cloth clamping plate 209. The upper clamping control arm 210 controls the upper left cloth clamping plate 208 and the upper right cloth clamping plate 209 to clamp or release the cloth. The cloth between the upper left cloth clamping plate 208 and the upper right cloth clamping plate 209 is transported to the upper cloth clamping guide roller 207 above the upper left cloth clamping plate 208 and the upper right cloth clamping plate 209. The upper cloth clamping guide roller 207 is used to transport the cloth to the upper cloth outlet and cloth inlet guide roller 106.

[0054] Preferably, a cloth outlet guide roller 5 is arranged directly below the cloth outlet guide roller 4, and the cloth outlet guide roller 5 and the cloth inlet guide roller 6 are on the same horizontal plane to ensure the coordinated stability of the entire cloth monitoring static sampling device based on clamping of the splint.

[0055] Preferably, a slide 9 is provided in the fabric monitoring sampling frame, and the slide 9 is the two end portions of two groups of distributed fabric buffer fixed seats 109. The fabric buffer fixed seats 109 can move up and down along the slide 9 on the corresponding side as a slider, so as to realize the upward and downward synchronous movement of the lower fabric feeding transmission guide roller 104 and the upper fabric discharging transmission guide roller 107 in the fabric buffer mechanism 1.

[0056] Preferably, the buffer damping mechanism 3 is divided into two groups, which are distributed below the corresponding side slide 9. The buffer damping mechanism 3 includes a buffer damping base 301 and a force unloading pendulum 302. The force unloading pendulum 302 is arranged on the buffer damping base 301. The force unloading pendulum 302 is used to unload the impact force of the free fall of the cloth buffer fixing seat 109. The mass of each force unloading pendulum 302 is the cloth buffer fixing seat 109, the lower cloth feed transmission guide roller 104, and the lower cloth feed cloth outlet guide roller. 105 constitutes half of the overall mass. The cache damping mechanism 3 can drop the fabric cache fixing seat 109 in the fabric cache mechanism 1 to the initial point and hit the unloading pendulum 302 at the bottom. The mass of the unloading pendulum 302 on both sides is almost equal to that of the entire fabric cache fixing seat 109. The collision process transfers all the kinetic energy of the fabric cache fixing seat 109 to the pendulum. The pendulum completes a swing and consumes the kinetic energy, and the pendulum stops. At the same time, the clamp is clamped again to start the next static sampling scan.

[0057] Preferably, the surfaces of the lower left cloth clamping plate 204, the lower right cloth clamping plate 205, the upper left cloth clamping plate 208, and the upper right cloth clamping plate 209 are covered with a wear-resistant and oxidation-resistant silicone layer, each cloth clamping plate is an I-shaped structure, and both sides of each cloth clamping plate are provided with a V-shaped force guiding groove 211, the V-shaped force guiding groove 211 can ensure that the force can be evenly transmitted to the entire clamping surface when pressure is applied at both ends of the clamping plate, thereby improving the clamping effect, and the surface of the clamping plate is covered with a wear-resistant and oxidation-resistant silicone layer, which will not cause pollution and damage to the cloth while ensuring friction.

In addition, the roller surface has a variety of treatment methods to meet the requirements of cloths with different friction coefficients.

[0059] The control method of the static sampling device for monitoring cloth based on clamping of the clamping plate of the present invention comprises the following steps:

[0060] Step (A), such as Figure 1 and Figure 2 As shown, the cloth 7 is passed through the cloth feed guide roller 6, the lower cloth feed guide roller 103, the lower cloth feed transmission guide roller 104, the lower cloth feed outlet guide roller 105, the lower cloth clamping guide roller 203, the upper cloth clamping guide roller 207, the upper cloth outlet cloth feed guide roller 106, the upper cloth outlet transmission guide roller 107 and the upper cloth outlet guide roller 108, the cloth outlet guide roller 4, and the cloth outlet guide roller 5 in sequence, and completely passes through the cloth monitoring static sampling device. At this time, the area between the upper cloth clamping unit 202 and the lower cloth clamping unit 201 is the static sampling area 8;

[0061] Step (B), the cloth is normally transmitted, the upper left cloth clamping plate 208 and the upper right cloth clamping plate 209 in the upper cloth clamping unit 202 and the lower left cloth clamping plate 204 and the lower right cloth clamping plate 205 in the lower cloth clamping unit 201 perform a clamping action, the cloth between the upper cloth clamping unit 202 and the lower cloth clamping unit 201 is in a stationary state, and static scanning and sampling are performed by an industrial camera;

[0062] Step (C), the continuously transported fabric will lift the fabric buffer fixing seat 109 in the fabric buffer mechanism 1, the lower fabric inlet buffer unit continues to absorb the transported fabric, and the upper fabric outlet buffer unit releases the buffered fabric to maintain the fabric inlet and outlet uniform speed transport;

[0063] Step (D), after the industrial camera completes static scanning and sampling, the upper left cloth clamping plate 208 and the upper right cloth clamping plate 209 in the upper cloth clamping unit 202 and the lower left cloth clamping plate 204 and the lower right cloth clamping plate 205 in the lower cloth clamping unit 201 are released, and the lifted cloth buffer fixed seat 109 is instantly unloaded and falls freely along the slideway 9, and the upper cloth buffer unit will pull the cloth between the upper cloth clamping unit 202 and the lower cloth clamping unit 201 into the buffer, and the lower cloth buffer unit will release the previously absorbed cloth to the upper cloth clamping unit 202 and the lower cloth clamping unit 201 until the cloth buffer fixed seat 109 returns to the starting point;

[0064] Step (E), the cloth buffer fixing seat 109 returns to the starting point, and the impact force of its free fall is unloaded through the buffer damping mechanism 3;

[0065] In step (F), the buffer damping mechanism 3 is reset, and the process returns to step (B) to perform the next industrial camera static scanning sampling.

[0066] The static sampling device for monitoring cloth based on clamping of the present invention achieves static sampling in motion during the whole process. Under the premise of ensuring that the cloth enters and exits the machine at a constant speed, short-stop stability of any period and cloth length can be achieved inside the machine. The stepping structure does not require servo, does not require additional power, has a light structure weight, low energy consumption, low resistance, and can work completely independently. A slideway is provided to adjust the height up and down to change the cloth length of the short stop. The stepping cycle can be changed by adjusting the speed of the cloth entering and exiting. According to the speed of the cloth entering and exiting and the length of the static sampling area between the upper cloth clamping unit 202 and the lower cloth clamping unit 201, the three can be adjusted at will according to the stepping cycle to meet the static sampling process of different cloths.

[0067] In summary, the control method of the static sampling device for monitoring cloth based on clamping of the present invention achieves static in motion during the whole process. Under the premise of ensuring the constant speed of cloth in and out, short-stop stability of any period and cloth length can be achieved inside the machine. The stepping structure does not require servo, does not require additional power, has a light structure, low energy consumption, low resistance, and completely autonomous operation. The slideway can be adjusted up and down in height to change the cloth length of the short stop. The speed of cloth in and out can be adjusted to change the stepping cycle, which greatly improves the accuracy of cloth monitoring and has good application prospects.
