Description

Technical Field

[0001] The present invention relates to the technical field of cloth inspection equipment, in particular to a cloth inspection machine for textile production with a fixed-length cutting function. Background Art

[0002] A fabric inspection machine is a device used to inspect fabric quality and cut it to length. Traditional fabric inspection machines typically consist of a frame, feed rollers, take-up rollers, a meter counter, and a cutting mechanism. As the fabric is conveyed, a meter counter (such as an encoder or meter wheel) measures its length. When the preset value is reached, the cutting mechanism automatically cuts the fabric. Some machines also feature guide rollers or tension adjustment mechanisms to reduce fabric deviation and wrinkling. However, existing fabric inspection machines still face the following issues during the cut-to-length process: Because fabric is soft and easily deformed, it can wrinkle or shift laterally during conveyance, leading to poor contact between the meter wheel and the fabric, causing it to slip or skip, and causing the actual cut length to differ from the set value. Some machines use fixed spreading rollers or simple tension adjustment, but even at high speeds, it is still difficult to ensure that the fabric is completely flat, affecting meter counting and cutting accuracy.

[0003] In response to the above problems, existing technologies have also provided some solutions. For example, multiple sets of cloth guide rollers or cloth pressing devices are used to reduce cloth wrinkles through physical pressing, but this can easily affect the surface quality of the cloth or increase running resistance. Another example is adding photoelectric sensors or correction systems to the cloth transmission path to monitor and adjust the cloth position in real time, but the system is complex and has a delayed response to high-speed cloth.

[0004] Therefore, there is an urgent need for a length-fixing solution for a cloth inspection machine with a simple structure and quick response to ensure that the cloth remains flat during the meter counting and cutting process, and to improve the accuracy and reliability of cloth length cutting. Summary of the Invention

[0005] The purpose of the present invention is to provide a cloth inspection machine for textile production with a fixed-length cutting function, so as to solve the problem that when the cloth inspection machine is measuring the length, the cloth is easily wrinkled or offset, causing the cloth and the length measuring device to slip or skip, resulting in deviation in the length measurement of the cloth.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A cloth inspection machine for textile production with a fixed-length cutting function includes a housing of the cloth inspection machine. Specifically, an intelligent sensing system for fixing the length of cloth is provided in the housing. The intelligent sensing system includes a meter counter, a camera module, a lighting module, and an information processing module. The housing is provided with a window that passes through both sides of the housing. A tilted support plate is provided in the window. The meter counter includes a meter counter body and two meter wheels. The meter counter body is installed on the lower side of the support plate. The two meter wheels are rotatably installed on the left and right sides of the meter counter body. The two meter wheels are extended to the upper side of the support plate and are connected to the fabric in a rolling manner. The fabric in the housing is provided with a horizontally conveyed fabric flat section. The camera module and the light module are both provided on the upper side of the fabric flat section, and the camera module is higher than the light module. The camera module, the light module and the meter body are all electrically connected to the information processing module. A spreading assembly is provided on the support plate. The spreading assembly is connected to the lower surface of the fabric in a rolling manner and is designed to provide tension to the lower surface of the fabric toward the left and right sides.

[0008] It should be noted that a cloth receiving module and a cloth feeding module are respectively provided on the front and rear sides of the casing, the window is provided between the cloth receiving module and the cloth feeding module, and a cutter module is provided between the lower front end of the support plate and the cloth receiving module. The cloth feeding module is used to transport cloth, the cloth receiving module is used to roll up cloth, and the cutter module is used to cut cloth. The cloth feeding module, cloth receiving module and cutter module are all electrically connected to the information processing module.

[0009] Preferably, the spreading assembly includes a No. 1 spreading roller and a No. 2 spreading roller, and the No. 1 spreading roller and the No. 2 spreading roller are both rotatably mounted on the support plate, and the No. 1 spreading roller and the No. 2 spreading roller are installed in an "eight" shape, and the tangential speeds of the connection between the No. 1 spreading roller and the cloth are both toward the outside of the cloth, and the No. 1 spreading roller and the No. 2 spreading roller are symmetrical about the center line of the meter body, and the upper and lower ends of the two extend beyond the forward projection range of the window.

[0010] When inspecting the cloth, the cloth is transported from the cloth feeding module located on the rear side of the casing to the inside of the casing. The cloth entering the casing passes through the upper side of the support plate. The staff can observe the quality of the cloth through the window. Finally, the cloth enters the cloth receiving module for winding. After the meter meter measures that the cloth has reached the set length, the cutting module is started, and the cutting module cuts the cloth, thereby completing the fixed length and automatic cutting of the cloth. In order to avoid wrinkles or deviations on the surface of the cloth when it passes through the meter wheel, which would cause errors in the cloth length setting by the meter wheel, a No. 1 spreading roller and a No. 2 spreading roller are symmetrically arranged on the left and right sides of the meter meter body, and the No. 1 spreading roller and the No. 2 spreading roller are in an "eight" shape with the opening facing downwards. When the cloth is conveyed to the upper side of the support plate, the No. 1 spreading roller and the No. 2 spreading roller act on the bottom of the cloth to spread the left and right sides of the cloth respectively; at the same time, by setting the length of the No. 1 spreading roller and the No. 2 spreading roller so that both the upper and lower ends extend beyond the forward projection range of the viewing window, it is ensured that the cloth is in an unfolded state after being conveyed to the lower side of the viewing window, thereby ensuring that the cloth is in an unfolded state when it is conveyed to the meter wheel, avoiding the wrinkles or deflected parts on the cloth acting on the meter wheel, causing skipping or slipping between the meter wheel and the cloth, thereby ensuring the accuracy of the cloth length setting.

[0011] By arranging an intelligent sensing system in the casing: a meter, a camera module, a lighting module and an information processing module, when the cloth is conveyed to the cloth flat section, the lighting module fills the upper end surface of the cloth flat section with light, the camera module collects data on the upper end surface of the cloth flat section, and transmits the collected cloth information to the information processing module, the information processing module processes the collected cloth information and compares it with the cloth standard model stored in the information processing module, if a cloth defect occurs in the cloth, the cloth defect will be recorded and prompted to the staff, thereby achieving an automatic cloth inspection effect.

[0012] Furthermore, the camera module can also transmit the collected fabric information to the information processing module. The information processing module calculates the length of the flat section of the fabric through an algorithm, thereby achieving auxiliary fixed length of the fabric. The information processing module compares the fabric length information collected by the camera module with the fabric length information collected by the meter counter to determine the actual length of the fabric. The accuracy of the fabric length fixed by the fabric inspection machine is guaranteed through the intelligent sensing system.

[0013] Preferably, a No. 1 thread strip and a No. 2 thread strip are respectively provided on the outer side walls of the No. 1 spreading roller and the No. 2 spreading roller, the No. 1 thread strip is left-handed, and the No. 2 thread strip is right-handed.

[0014] By arranging a left-handed No. 1 thread strip on the outer side wall of the No. 1 spreading roller and a right-handed No. 2 thread strip on the outer side wall of the No. 2 spreading roller, when the cloth is conveyed to the support plate, the No. 1 thread strip and the No. 2 thread strip both fit with the lower end surface of the cloth, and the tangential speeds of the connection between the No. 1 spreading roller and the No. 2 spreading roller and the cloth are all toward the outside of the cloth: the No. 1 spreading roller rotates to the left, and the No. 2 spreading roller rotates to the right; the No. 1 thread strip acts on the left side of the cloth , pushing the cloth to the left and downward, the No. 2 threaded strip acts on the right side of the cloth, pushing the cloth to the right and downward, thereby completing the unfolding and conveying of the cloth, ensuring that the cloth is in an unfolded state after being conveyed to the lower side of the window, thereby avoiding the cloth being in an unfolded state when being conveyed to the meter wheel, avoiding the wrinkles or offset parts on the cloth acting on the meter wheel, causing skipping or slipping between the meter wheel and the cloth, thereby ensuring the accuracy of the cloth fixed length.

[0015] Preferably, a No. 4 spreading roller and a No. 3 spreading roller are respectively provided at the front and rear ends of the fabric spreading section, the No. 3 spreading roller is arranged at the lower side of the rear end of the fabric spreading section, and the No. 4 spreading roller is arranged at the upper side of the front end of the fabric spreading section, and No. 3 thread strips and No. 4 thread strips are provided on the outer side walls of the No. 3 spreading roller and the No. 4 spreading roller, and the No. 3 thread strips and No. 4 thread strips are respectively symmetrically arranged on the left and right sides, the No. 3 thread strip arranged on the left is left-handed, and the No. 4 thread strip arranged on the right is right-handed, and the No. 3 spreading roller and the No. 4 spreading roller are both provided with independent driving motors, the No. 3 spreading roller and the No. 4 spreading roller have the same rotation direction, and the driving motors of both are electrically connected to the information processing module.

[0016] By arranging a No. 4 spreading roller and a No. 3 spreading roller at the front and rear ends of the fabric flattening section respectively, when the fabric is conveyed to the fabric flattening section, in order to avoid wrinkles or deviations of the fabric in the fabric flattening section, which causes errors in the information collected by the camera module, thereby affecting the accuracy of the fabric fixed length, the driving motor of the No. 3 spreading roller is started through the information processing module, so that the force of the No. 3 spreading roller acting on the fabric is directed to the rear side, and then the driving motor of the No. 4 spreading roller is started through the information processing module, so that the force of the No. 4 spreading roller acting on the fabric is directed to the front side, so that the fabric flattening section The fabric in the paving section is in a taut state; at the same time, by providing symmetrical No. 3 thread strips and No. 4 thread strips on both the No. 3 spreading roller and the No. 4 spreading roller, and the No. 3 thread strips are left-handed and the No. 4 thread strips are right-handed, during the rotation of the No. 3 spreading roller and the No. 4 spreading roller, the No. 3 thread strip acts on the fabric and spreads the fabric to the left, and the No. 4 thread strip acts on the fabric and spreads the fabric to the right, thereby ensuring that the fabric on the fabric paving section is in a flat state, ensuring the accuracy of the fabric information collected by the camera module, and further ensuring the accuracy of the fabric fixed length.

[0017] It should be noted that, at the front and rear ends of the support plate, a combination of, for example, a No. 3 spreading roller and a No. 4 spreading roller can also be set for spreading. However, in the combination of the No. 3 spreading roller and the No. 4 spreading roller, the direction of the force exerted by the No. 3 spreading roller on the fabric is downward and rearward, which is opposite to the conveying direction of the fabric, and will reduce the inspection efficiency of the fabric inspection machine. Therefore, the combination of the No. 3 spreading roller and the No. 4 spreading roller for spreading is not a preferred solution for the spreading structure on the support plate; further, a combination of, for example, a No. 1 spreading roller and a No. 2 spreading roller can also be set on the fabric flattening section for spreading. However, the spreading speed of the No. 1 spreading roller and the No. 2 spreading roller is slow, and in order to ensure that the fabric captured by the camera module In order to ensure the accuracy of the fabric information, the camera module needs to complete the spreading before it can measure the fabric information of the fabric, and in order to ensure the regionality and delay of the fabric information taken by the camera module, the fabric information collected by the camera module at a single time is the fabric information of a section of fabric. In order to reduce the overlap of the information of two adjacent sections of fabric, the length of the fabric flat section needs to be the unfolded length of the No. 1 spreading roller and the No. 2 spreading roller plus the length of the collection area of ​​the camera module, which will cause the length of the fabric flat section to be longer than the fabric flat section with the No. 3 spreading roller and the No. 4 spreading roller, increasing the size of the fabric inspection machine. Therefore, the combination of the No. 1 spreading roller and the No. 2 spreading roller for spreading is not a preferred solution for the spreading structure of the fabric flat section.

[0018] Preferably, a No. 1 tension roller is provided in the casing, and the No. 1 tension roller is arranged on the lower side of the front end of the support plate. The cutter module is arranged between the No. 1 tension roller cloth collecting module, and a No. 3 thread strip and a No. 4 thread strip are provided on the outer side wall of the No. 1 tension roller, and the No. 3 thread strip and the No. 4 thread strip are symmetrically arranged on the left and right sides of the No. 1 tension roller respectively.

[0019] By arranging a No. 1 tension roller between the support plate and the cloth collecting module, after the cloth is separated from the No. 1 inner thread strip and the No. 2 thread strip, the lower surface of the cloth contacts the No. 3 thread strip and the No. 4 thread strip on the No. 1 tension roller. The force exerted on the cloth by the No. 1 tension roller is toward the front side, and the thread strip and the No. 3 thread strip on the No. 1 tension roller provide the cloth with a leftward unfolding force and a rightward unfolding force respectively, thereby unfolding the cloth, avoiding the cloth from wrinkling or deflecting again after being separated from the No. 1 unfolding roller and the No. 2 unfolding roller, thereby affecting the accuracy of cloth cutting and causing the cloth to have inaccurate length after the cloth inspection is completed, thereby ensuring the accuracy of the cloth fixed length.

[0020] Preferably, the cross-sections of the No. 1 thread bar, the No. 2 thread bar, the No. 3 thread bar and the No. 4 thread bar are all rectangular, and deformation cavities are provided inside the four, and the four are all made of soft rubber material.

[0021] By setting the cross-sections of the No. 1, No. 2, No. 3 and No. 4 thread strips to be rectangular, the friction area between the four and the cloth is increased, thereby avoiding slipping between the four and the cloth due to the small friction area, resulting in a decrease in the unfolding effect of the four on the cloth, thereby ensuring the unfolding of the cloth; at the same time, the four are all made of soft rubber material, and are provided with a deformation cavity inside. During the transportation of the cloth, the cloth squeezes the No. 1, No. 2, No. 3 or No. 4 thread strips when it fluctuates, and the deformation cavity is deformed. The deformed deformation cavity will increase the surface area of ​​the No. 1, No. 2, No. 3 or No. 4 thread strips, increase the contact area between the deformation position and the cloth, thereby increasing the friction area, ensuring that the cloth will not deviate, and thus ensuring the accuracy of the fixed length of the cloth.

[0022] Preferably, a conveying module is provided on the lower side of the support plate, and the conveying module includes a screw rod, a guide rod, a support seat, a nut and a servo motor. The screw rod is rotatably connected to the support plate, one end of the screw rod is fixedly connected to the conveying end of the servo motor, the servo motor is electrically connected to the information processing module, the nut is threadedly connected to the screw rod, and the nut is fixedly installed in the support seat, the guide rod is arranged parallel to the screw rod, and the two ends of the screw rod are fixedly connected to the support plate, the support seat is slidably connected to the guide rod, and the meter body is arranged on the upper side of the support seat.

[0023] When the cloth inspection machine is inspecting cloths of different widths, the cloth information is collected by the camera module. After the cloth information is transmitted to the information processing module, the information processing module processes the cloth information to obtain the cloth width information. Through the setting of the No. 3 spreading roller and the No. 4 spreading roller, the unfolding effect of the cloth flat section is guaranteed, thereby ensuring the accuracy of the cloth width information collected by the camera module.

[0024] Furthermore, when fabrics of different widths are conveyed to the window position, the position of the fabric after being fully unfolded by the No. 1 spreading roller and the No. 2 spreading roller changes. By arranging the No. 1 tensioning roller on the lower side of the support plate, the fabric is in a taut state between the position after being fully unfolded on the support plate and the No. 1 tensioning roller, thereby avoiding the problem of skipping or slipping between the meter wheel and the fabric, thereby ensuring the accuracy of the fixed length of the fabric.

[0025] Furthermore, after the width information of the fabric is obtained through processing by the information processing module, the servo motor is controlled by the information processing module, and the servo motor drives the screw to rotate, and the screw drives the support seat to move in the axial direction of the screw, and the meter counter body and the meter wheel follow the movement of the support seat. The driver of the information processing module drives the meter wheel to a position where the fabric is just unfolded by the No. 1 spreading roller and the No. 2 spreading roller, thereby ensuring that the fabric is in an unfolded state when it is transported to the meter wheel, avoiding the wrinkles or offset parts on the fabric acting on the meter wheel, causing skipping or slipping between the meter wheel and the fabric, thereby ensuring the accuracy of the fabric length setting.

[0026] Preferably, the upper side of the support base is provided with at least four mounting holes, and the lower end of the meter counter body is provided with a number of latches matching the number of mounting holes, the latches slidably mounted within the mounting holes. An adjustment spring is provided between the meter counter body and the support base, with the ends of the adjustment spring fixedly connected to the meter counter body and the support base, respectively. When the fabric undulates, the adjustment spring ensures that the meter wheel maintains contact with the lower surface of the fabric, preventing skipping or slipping between the meter wheel and the fabric, thereby ensuring accurate fabric length control.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention provides a No. 1 spreading roller and a No. 2 spreading roller symmetrically on the left and right sides of the meter counter body, and the two rollers are arranged in an "eight" shape with their openings facing downward. The two rollers spread the left and right sides of the cloth to the left and right respectively. At the same time, the lengths of the two rollers are set so that both the upper and lower ends extend beyond the forward projection range of the viewing window, ensuring that the cloth is in a spread state after being conveyed to the lower side of the viewing window, avoiding the problem of wrinkles or offset parts on the cloth acting on the meter wheel, causing skipping or slipping between the meter wheel and the cloth, thereby ensuring the accuracy of the cloth fixed length.

[0029] 2. The present invention is provided with an intelligent sensing system including a meter counter, a camera module, a lighting module and an information processing module. The camera module transmits the collected fabric information to the information processing module. The information processing module calculates the length of the flat section of the fabric through an algorithm, thereby realizing auxiliary fixed length of the fabric. The information processing module compares the fabric length information collected by the camera module with the fabric length information collected by the meter counter to determine the actual length of the fabric, thereby ensuring the accuracy of the fabric fixed length. At the same time, the information processing module can also process the fabric information to realize automatic fabric inspection.

[0030] 3. The present invention sets a No. 1 tension roller between the meter counter and the cutter module. The threaded strips on the No. 1 tension roller and the No. 3 threaded strips respectively provide leftward and rightward unfolding forces for the cloth, thereby unfolding the cloth and preventing the cloth from wrinkling or deflecting again after it leaves the No. 1 unfolding roller and the No. 2 unfolding roller, thereby affecting the accuracy of cloth cutting and causing the problem of inaccurate length of the cloth after the cloth inspection is completed, thereby ensuring the accuracy of the cloth fixed length.

[0042] Working principle: When inspecting the fabric 11, the fabric 11 is passed through the back side of the fabric inspection machine. The fabric 11 first passes under the No. 1 feed roller 201, and then passes over the No. 3 spreading roller 15.

After passing over the No. 3 spreading roller 15, the fabric 11 passes over the support roller 202. Then, the fabric 11 The cloth 11 passes through the bottom of the No. 4 spreading roller 16. At this time, the surfaces of the No. 3 thread strip 1501 and the No. 4 thread strip 1502 on the No. 4 spreading roller 16 are in contact with the upper surface of the cloth 11. The cloth 11 forms a cloth flat section 12 between the No. 3 spreading roller 15 and the No. 4 spreading roller 16. After passing through the No. 4 spreading roller 16, the cloth 11 passes through the bottom of the transition roller 204 and then passes through the top of the No. 3 feeding roller 205. Then, the cloth 11 passes between the support plate 6 and the shell. After the cloth 11 completely passes through the support plate 6 and reaches the lower side of the support plate 6, the No. 1 spreading roller 13, the No. 2 spreading roller 14 and the meter wheel 402 are all in contact with the lower surface of the cloth 11; then, the cloth 11 passes over the No. 1 tension roller 7, and then the cloth 11 moves downward. After the cloth 11 reaches the lower side of the shell, it is fixedly connected to the winding roller 503. The winding roller 503 connected with the cloth 11 is placed between the No. 1 cloth-collecting roller 501 and the No. 2 cloth-collecting roller 502. When the cloth 11 is conveyed, observing from left to right, the No. 1 cloth feed roller 201, the No. 3 cloth spreading roller 15, the No. 4 cloth spreading roller 16, the No. 1 cloth collecting roller 501 and the No. 2 cloth collecting roller 502 all rotate counterclockwise, and the No. 2 cloth feed roller 203, the No. 3 cloth feed roller 205 and the No. 1 tension roller 7 all rotate clockwise. Observing the No. 1 cloth spreading roller 13 and the No. 2 cloth spreading roller 14 from the positive perspective of the window 101, the No. 1 cloth spreading roller 13 rotates to the left, and the No. 2 cloth spreading roller 14 rotates to the right.

[0043] During the conveying process of the cloth 11, the information processing module 10 controls the illumination intensity of the lighting module 9 to adapt to the cloth 11 of different colors. The camera module 8 takes pictures of the cloth 11 in the cloth flat section 12 and transmits the photographed cloth 11 information to the information processing module 10. The information processing module 10 compares the photographed cloth 11 information with the data in the database of the information processing module 10. If a defect in the cloth 11 occurs, the information processing module 10 controls the labeling machine 22 to run on the guide rail 21 to the width position of the corresponding cloth 11 defect by identifying the width position of the defect, and then reads the width position of the defect. The meter counter 4 measures the length data of the cloth 11, and controls the labeling machine 22 to perform labeling when the defect of the cloth 11 reaches the lower side of the labeling machine 22 (existing technology, no longer described here), thereby completing the marking of the defect of the cloth 11; when the meter counter 4 measures that the cloth 11 meets the length requirement, the information processing module 10 obtains the condition by reading the electrical signal of the meter counter body 401, thereby driving the cutter body 302 to move toward the cutter seat 303, thereby cutting the cloth 11 after the fixed length is completed. After the cutting process, the cloth 11 is transported to the next process, and a new winding roller 503 is replaced and the above actions are repeated to carry out continuous cloth inspection.
