Description

Technical Field

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

[0002] A fabric inspection machine is a device used to detect the quality of fabrics and perform fixed-length cutting; traditional fabric inspection machines generally include a frame, a fabric feeding roller, a fabric receiving roller, a length meter, and a cutting device. During the fabric conveying process, the length is measured by a length meter (such as an encoder or a length measuring wheel). When the preset value is reached, the cutting device automatically cuts the fabric. Some devices are also equipped with fabric guiding rollers or tension adjusting mechanisms to reduce fabric deviation or wrinkling problems. However, the existing fabric inspection machines still have the following problems during the fixed-length process: Since the fabric is soft and easily deformed, local wrinkles or lateral offsets may occur during the conveying process, resulting in poor contact between the length measuring wheel and the fabric, slipping or skipping phenomena, and causing the actual cutting length to not match the set value; some devices use fixed spreading rollers or simple tension adjustment, but it is still difficult to ensure the fabric is completely flat during high-speed operation, affecting the length measurement and cutting accuracy.

[0003] In response to the above problems, some solutions have also been provided in the prior art. For example, multiple groups of fabric guiding rollers or fabric pressing devices are used to reduce fabric wrinkles through physical pressing, but it is easy to affect the surface quality of the fabric or increase the running resistance; another example is to add photoelectric sensors or deviation correction systems to the fabric transmission path to monitor the fabric position in real time and adjust it, but the system is complex and has a lag in response to high-speed running fabrics.

[0004] Therefore, there is an urgent need for a fixed-length solution for fabric inspection machines that is simple in structure and rapid in response to ensure that the fabric always remains flat during the length measurement and cutting processes, and improve the accuracy and reliability of the fixed-length cutting of the fabric. Summary of the Invention

[0005] The purpose of the present invention is to provide a fabric inspection machine for textile production with a fixed-length cutting function to solve the problem that when the fabric inspection machine measures the length, it is easy for the fabric to wrinkle or shift, causing slipping or skipping between the fabric and the length measurement device, resulting in deviation in the length measurement of the fabric.

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

[0007] A cloth inspection machine for textile production with a fixed-length truncation function, including the housing of the cloth inspection machine. Specifically, an intelligent sensing system for determining the length of the cloth is provided inside the housing. The intelligent sensing system includes a length meter, a camera module, a lighting module, and an information processing module. A window penetrating through both the inner and outer sides of the housing is provided on the housing. An inclined support plate is provided inside the window. The length meter includes a length meter body and two length measuring wheels. The length meter body is installed on the lower side of the support plate. The two length measuring wheels are rotatably installed on the left and right sides of the length meter body, and both extend to the upper side of the support plate to be in rolling connection with the cloth. A horizontally transported flat cloth section is provided for the cloth inside the housing. The camera module and the lighting module are both provided on the upper side of the flat cloth section, and the camera module is higher than the lighting module. The camera module, the lighting module, and the length meter body are all electrically connected to the information processing module. A cloth spreading component is provided on the support plate. The cloth spreading component is in rolling connection with the lower surface of the cloth, and is designed to provide tension towards the left and right sides for the lower surface of the cloth.

[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 housing. The window is provided between the cloth receiving module and the cloth feeding module. A cutting knife module is provided between the lower front side of the support plate and the cloth receiving module. The cloth feeding module is used to transport the cloth, the cloth receiving module is used to wind up the cloth, and the cutting knife module is used to cut the cloth. The cloth feeding module, the cloth receiving module, and the cutting knife module are all electrically connected to the information processing module.

[0009] Preferably, the cloth spreading component includes a first cloth spreading roller and a second cloth spreading roller. The first cloth spreading roller and the second cloth spreading roller are both rotatably installed on the support plate. The first cloth spreading roller and the second cloth spreading roller are installed in an "eight" shape. The tangential speeds at their connections with the cloth are both towards the outside of the cloth. The first cloth spreading roller and the second cloth spreading roller are symmetric about the center line of the length meter body, and both extend beyond the positive projection range of the window at their upper and lower ends.

[0010] When inspecting the fabric, the fabric is conveyed from the fabric feeding module provided at the rear side of the machine housing into the machine housing. The fabric entering the machine housing passes through the upper side of the support plate. The staff can observe the quality of the fabric through the viewing window, and finally enters the fabric winding module for winding. After the length measuring device measures that the conveyed fabric reaches the set length, the cutting module is started, and the cutting module cuts off the fabric, thereby completing the fixed-length and automatic cutting of the fabric. In order to prevent wrinkles or offsets on the surface of the fabric when passing through the length measuring wheel, which may cause errors in the fixed length of the fabric measured by the length measuring wheel, therefore, a first fabric spreading roller and a second fabric spreading roller are symmetrically arranged on the left and right sides of the length measuring device body, and the first fabric spreading roller and the second fabric spreading roller are in an "eight" shape with the opening facing downwards. When the fabric is conveyed to the upper side of the support plate, the first fabric spreading roller and the second fabric spreading roller act on the lower surface of the fabric to spread the left and right sides of the fabric to the left and right respectively; at the same time, by setting the lengths of the first fabric spreading roller and the second fabric 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 fabric must be in a spread state after being conveyed to the lower side of the viewing window, thereby ensuring that the fabric is in a spread state when conveyed to the length measuring wheel, avoiding the problem of skipping or slipping between the length measuring wheel and the fabric caused by the wrinkled or offset part on the fabric, and thus ensuring the accuracy of the fixed length of the fabric.

[0011] By setting an intelligent sensing system in the machine housing: a length measuring device, a camera module, a lighting module and an information processing module, when the fabric is conveyed to the fabric laying section, the lighting module fills light on the upper end surface of the fabric laying section, the camera module collects data on the upper end surface of the fabric laying section, and conveys the collected fabric information to the information processing module. The information processing module processes the collected fabric information and compares it with the fabric standard model stored in the information processing module. If there are fabric defects, the fabric defects are recorded and prompted to the staff, thereby realizing the effect of automatic fabric inspection.

[0012] Furthermore, the camera module can also convey the collected fabric information to the information processing module. The information processing module calculates the length of the fabric passing through the fabric laying section through an algorithm, thereby realizing the auxiliary fixed length of the fabric. The information processing module compares and processes the fabric length information collected by the camera module with the fabric length information collected by the length measuring device to determine the actual length of the fabric, ensuring the accuracy of the fixed length of the fabric by the fabric inspection machine through the intelligent sensing system.

[0013] Preferably, a first threaded strip and a second threaded strip are respectively provided on the outer side walls of the first fabric spreading roller and the second fabric spreading roller. The first threaded strip is left-handed and the second threaded strip is right-handed.

[0014] By providing a left-handed first thread strip on the outer sidewall of the first spreading roller and a right-handed second thread strip on the outer sidewall of the second spreading roller, when the fabric is conveyed to the support plate, both the first thread strip and the second thread strip are in contact with the lower end surface of the fabric. Considering that the tangential speeds at the connection points of the first spreading roller and the second spreading roller with the fabric are both directed towards the outside of the fabric: the first spreading roller rotates counterclockwise, and the second spreading roller rotates clockwise; the first thread strip acts on the left side of the fabric, pushing the fabric to the left and downward, and the second thread strip acts on the right side of the fabric, pushing the fabric to the right and downward, thus completing the unfolding and conveying of the fabric, ensuring that the fabric must be in an unfolded state after being conveyed to the lower side of the viewing window, thereby preventing the fabric from being in an unfolded state when it reaches the length measuring wheel, and avoiding the problem that the wrinkled or offset parts on the fabric act on the length measuring wheel, causing skipping or slipping between the length measuring wheel and the fabric, thus ensuring the accuracy of the fabric length measurement.

[0015] Preferably, a fourth spreading roller and a third spreading roller are respectively provided at the front and rear ends of the fabric laying section. The third spreading roller is provided at the lower side of the rear end of the fabric laying section, and the fourth spreading roller is provided at the upper side of the front end of the fabric laying section. Third thread strips and fourth thread strips are provided on the outer sidewalls of the third spreading roller and the fourth spreading roller. The third thread strips and the fourth thread strips are symmetrically arranged on the left and right sides respectively. The third thread strip on the left side is left-handed, and the fourth thread strip on the right side is right-handed. The third spreading roller and the fourth spreading roller are both provided with independent drive motors. The rotation directions of the third spreading roller and the fourth spreading roller are the same, and the drive motors of both are electrically connected to the information processing module.

[0016] By respectively providing a fourth spreading roller and a third spreading roller at the front and rear ends of the fabric laying section, when the fabric is conveyed to the fabric laying section, to avoid wrinkles or offsets in the fabric of the fabric laying section, which may cause errors in the information collected by the imaging module and thus affect the accuracy of the fabric length measurement, the drive motor of the third spreading roller is started through the information processing module, so that the force exerted by the third spreading roller on the fabric is directed backward. Then, the drive motor of the fourth spreading roller is started through the information processing module, so that the force exerted by the fourth spreading roller on the fabric is directed forward, thereby making the fabric located in the fabric laying section in a taut state; at the same time, by providing symmetric third thread strips and fourth thread strips on both the third spreading roller and the fourth spreading roller, and the third thread strip is left-handed, and the fourth thread strip is right-handed. During the rotation of the third spreading roller and the fourth spreading roller, the third thread strip acts on the fabric and unfolds the fabric to the left side, and the fourth thread strip acts on the fabric and unfolds the fabric to the right side, thus ensuring that the fabric on the fabric laying section is in a flattened state, ensuring the accuracy of the fabric information collected by the imaging module, and further ensuring the accuracy of the fabric length measurement.

[0017] It should be noted that combinations such as a third spreading roller and a fourth spreading roller can also be provided at the front and rear ends of the support plate for spreading. However, in the combination of the third spreading roller and the fourth spreading roller, the acting force direction of the third spreading roller on the fabric is downward and rearward, which is opposite to the conveying direction of the fabric, and will reduce the fabric inspection efficiency of the fabric inspection machine. Therefore, the combination of the third spreading roller and the fourth spreading roller for spreading is not an optimal solution for the spreading structure on the support plate; furthermore, a combination such as a first spreading roller and a second spreading roller can also be provided on the fabric laying section for spreading. However, the spreading speed of the first spreading roller and the second spreading roller is relatively slow. In order to ensure the accuracy of the fabric information collected by the camera module, the camera module needs to measure the fabric information after the spreading is completed. And in order to ensure the regionality and latency of the fabric information collected by the camera module, the fabric information collected by the camera module each time is the fabric information of a section of fabric. In order to reduce the coincidence of the fabric information of adjacent two sections of fabric, the length of the fabric laying section needs to be the unfolded length of the first spreading roller and the second spreading roller plus the acquisition area length of the camera module, which will cause the length of the fabric laying section to be longer than the fabric laying section provided with the third spreading roller and the fourth spreading roller, increasing the size of the fabric inspection machine. Therefore, the combination of the first spreading roller and the second spreading roller for spreading is not an optimal solution for the spreading structure of the fabric laying section.

[0018] Preferably, a first tension roller is provided inside the machine shell. The first tension roller is provided on the lower side of the front end of the support plate. The cutting knife module is arranged between the first tension roller and the cloth receiving module. Third threaded strips and fourth threaded strips are provided on the outer side wall of the first tension roller. The third threaded strip and the fourth threaded strip are symmetrically arranged on the left and right sides of the first tension roller respectively.

[0019] By providing a first tension roller between the support plate and the cloth receiving module, after the fabric separates from the first threaded inner strip and the second threaded strip, the lower surface of the fabric contacts the third threaded strip and the fourth threaded strip on the first tension roller. The force exerted by the first tension roller on the fabric is forward, and the threaded strip and the third threaded strip on the first tension roller provide a leftward spreading force and a rightward spreading force for the fabric respectively, so as to unfold the fabric, avoid the fabric from generating wrinkles or shifting again after separating from the first spreading roller and the second spreading roller, thus affecting the accuracy of fabric cutting and causing the problem of inaccurate length of the fabric after the fabric inspection is completed, and ensuring the accuracy of fabric length determination.

[0020] Preferably, the cross-sections of the first threaded strip, the second threaded strip, the third threaded strip and the fourth threaded strip are all rectangular, and deformation cavities are provided inside all of them. All of them are made of soft rubber material.

[0021] By setting the cross-sections of the first threaded bar, the second threaded bar, the third threaded bar, and the fourth threaded bar as rectangles, the friction area between the four and the fabric is increased, thereby avoiding the problem that the four slip due to too small a friction area with the fabric, resulting in a decrease in the unfolding effect of the four on the fabric, and ensuring the unfolding of the fabric. At the same time, the four are all made of soft rubber material and are internally provided with deformation cavities. During the conveying process of the fabric, when the fabric undulates, it squeezes the first threaded bar, the second threaded bar, the third threaded bar, or the fourth threaded bar, and the deformation cavity deforms. The deformed deformation cavity will increase the surface area of the first threaded bar, the second threaded bar, the third threaded bar, or the fourth threaded bar, improve the contact surface between the deformed position and the fabric, thereby increasing the friction area, ensuring that the fabric does not shift, and thus ensuring the accuracy of the fixed length of the fabric.

[0022] Preferably, a conveying module is provided on the lower side of the support plate. The conveying module includes a lead screw, a guide rod, a support seat, a nut, and a servo motor. The lead screw is rotatably connected to the support plate. One end of the lead screw 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 lead screw. The nut is fixedly installed in the support seat. The guide rod is arranged parallel to the lead screw, and both ends of the lead screw are fixedly connected to the support plate. The support seat is slidably connected to the guide rod. The length measuring device body is arranged on the upper side of the support seat.

[0023] When the fabric inspection machine performs fabric inspection operations on fabrics of different widths, after collecting fabric information through the camera module and transmitting the fabric information into the information processing module, the information processing module processes the fabric information to obtain the width information of the fabric. Through the settings of the third fabric spreading roller and the fourth fabric spreading roller, the unfolding effect of the flat section of the fabric is ensured, thereby ensuring the accuracy of the fabric width information collected by the camera module.

[0024] Furthermore, when fabrics of different widths are conveyed to the window position, the position where the fabric is fully unfolded after passing through the first fabric spreading roller and the second fabric spreading roller changes. By providing a first tension roller on the lower side of the support plate, the section of the fabric between the position where it is fully unfolded on the support plate and the first tension roller is in a taut state, thereby avoiding the problem of skipping or slipping between the length measuring wheel and the fabric, and thus ensuring the accuracy of the fixed length of the fabric.

[0025] Further, after the width information of the fabric is obtained through the information processing module, the servo motor is controlled by the information processing module. The servo motor drives the lead screw to rotate, and the lead screw drives the support seat to move in the axial direction of the lead screw. The counter body and the counter wheel move along with the support seat. Through the driver program of the information processing module, the counter wheel is driven to a position where the fabric is just unfolded by the first fabric spreading roller and the second fabric spreading roller, so as to ensure that the fabric is in an unfolded state when it is conveyed to the counter wheel, avoiding the problem of skipping or slipping between the counter wheel and the fabric caused by the wrinkled or offset part of the fabric acting on the counter wheel, thus ensuring the accuracy of the fixed length of the fabric.

[0026] Preferably, at least four mounting holes are provided on the upper side of the support seat, and the lower end of the counter body is provided with the same number of pins as the mounting holes. The pins are slidably mounted in the mounting holes. An adjusting spring is provided between the counter body and the support seat, and both ends of the adjusting spring are fixedly connected to the counter body and the support seat respectively. When the fabric fluctuates, due to the arrangement of the adjusting spring, it is ensured that the counter wheel keeps in contact with the lower surface of the fabric, avoiding the problem of skipping or slipping between the counter wheel and the fabric, thus ensuring the accuracy of the fixed length of the fabric.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. In the present invention, the first fabric spreading roller and the second fabric spreading roller are symmetrically arranged on the left and right sides of the counter body, and both are arranged in an "eight" shape with the opening facing downwards. The left and right sides of the fabric are respectively unfolded to the left and right by the two, and at the same time, the lengths of both are set so that both ends extend beyond the positive projection range of the viewing window, ensuring that the fabric must be in an unfolded state after being conveyed to the lower side of the viewing window, avoiding the problem of skipping or slipping between the counter wheel and the fabric caused by the wrinkled or offset part of the fabric acting on the counter wheel, thus ensuring the accuracy of the fixed length of the fabric.

[0029] 2. The present invention sets up an intelligent sensing system including a counter, a camera module, a lighting module and an information processing module. The camera module conveys 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, so as to realize the auxiliary fixed length of the fabric. The information processing module compares and processes the fabric length information collected by the camera module with the fabric length information collected by the counter to determine the true length of the fabric, thus ensuring the accuracy of the fixed length of the fabric. At the same time, the information processing module can also process the fabric information to realize automatic fabric inspection.

[0030] 3. A first tension roller is arranged between the length counter and the cutting knife module of the present invention. The threaded bar on the first tension roller and the third threaded bar respectively provide a leftward unfolding force and a rightward unfolding force for the fabric, so as to unfold the fabric, avoid the fabric from generating new wrinkles or offsets after leaving the first unfolding roller and the second unfolding roller, thereby affecting the accuracy of fabric cutting, resulting in inaccurate length of the fabric after the fabric inspection is completed, and ensuring the accuracy of fabric length determination.

[0042] Working principle: When inspecting the fabric 11, the fabric 11 is threaded into the fabric inspection machine from the rear side of the machine. The fabric 11 first passes under the first fabric feeding roller 201, then passes above the third fabric spreading roller 15. At this time, the surfaces of the third thread bars 1501 and the fourth thread bars 1502 on the third fabric spreading roller 15 are in contact with the lower surface of the fabric 11. After the fabric 11 passes above the third fabric spreading roller 15, it then passes above the supporting roller 202. Immediately afterwards, the fabric 11 passes under the fourth fabric spreading roller 16. At this time, the surfaces of the third thread bars 1501 and the fourth thread bars 1502 on the fourth fabric spreading roller 16 are in contact with the upper surface of the fabric 11. The fabric 11 forms a fabric laying section 12 between the third fabric spreading roller 15 and the fourth fabric spreading roller 16. After the fabric 11 passes through the fourth fabric spreading roller 16, it passes under the transition roller 204 and then passes above the third fabric feeding roller 205. Immediately afterwards, the fabric 11 passes through the gap between the support plate 6 and the housing. After the fabric 11 completely passes through the support plate 6 and reaches the lower side of the support plate 6, the first fabric spreading roller 13, the second fabric spreading roller 14, and the length measuring wheel 402 are all in contact with the lower surface of the fabric 11. Immediately afterwards, the fabric 11 passes above the first tension roller 7. Subsequently, the fabric 11 moves downwards. After the fabric 11 reaches the lower side of the housing, it is fixedly connected to the winding roller 503. The winding roller 503 connected to the fabric 11 is placed between the first fabric receiving roller 501 and the second fabric receiving roller 502. When transporting the fabric 11, when observing from left to right, the first fabric feeding roller 201, the third fabric spreading roller 15, the fourth fabric spreading roller 16, the first fabric receiving roller 501, and the second fabric receiving roller 502 all rotate counterclockwise, and the second fabric feeding roller 203, the third fabric feeding roller 205, and the first tension roller 7 all rotate clockwise. When observing the first fabric spreading roller 13 and the second fabric spreading roller 14 from the front view angle of the viewing window 101, the first fabric spreading roller 13 rotates counterclockwise and the second fabric spreading roller 14 rotates clockwise.

[0043] During the conveying process of the fabric 11, the information processing module 10 controls the illumination intensity of the lighting module 9 to adapt to fabrics 11 of different colors. The imaging module 8 captures the information of the fabric 11 in the flat fabric section 12 and transmits the captured fabric 11 information to the information processing module 10. The information processing module 10 compares and processes the captured fabric 11 information with the data in the database of the information processing module 10. If there is a defect in the fabric 11, the information processing module 10 controls the labeling machine 22 to run on the guide rail 21 to the corresponding width position where the fabric 11 defect is located by identifying the width position of the fabric 11 defect. Then, by reading the fabric 11 length data measured by the length counter 4, the information processing module 10 controls the labeling machine 22 to perform a labeling action when the fabric 11 defect reaches the lower side of the labeling machine 22 (prior art, not elaborated here), thus completing the marking of the fabric 11 defect; when the length counter 4 measures that the fabric 11 meets the length requirement, the information processing module 10 obtains this condition by reading the electrical signal of the length counter body 401, thereby driving the cutter body 302 to move towards the cutter seat 303, so as to perform a cutting process on the fabric 11 after the fixed length is completed. After the cutting process is completed, the fabric 11 is transferred to the next process. By replacing the new winding roller 503 and repeating the above actions, continuous fabric inspection can be carried out.

For those skilled in the art, without departing from the principles and ideas of the present invention, various changes, modifications, substitutions, and variations made to these embodiments should still fall within the protection scope of the present invention.
