Description

Technical Field

[0001] This invention relates to the field of inspection equipment technology, and in particular to a fabric inspection device. Background Technology

[0002] After the fabric is produced, it needs to be inspected to reduce surface defects and improve product quality. Since conventional visual inspection by workers is prone to fatigue and defects are easily missed, some companies use testing devices to assist in the inspection of fabric, in order to reduce labor intensity and improve inspection quality.

[0003] Existing inspection devices, as shown in the patent application number CN202322529838.7, include a camera, a marker, and a roller. During inspection, the fabric moves forward under the action of the roller, the camera captures defects on the fabric, and the marker marks the defects. After the worker sees the mark, the worker needs to stop the inspection device. After the fabric stops moving, the worker manually repairs the defect at the mark. After the repair is completed, the inspection device restarts and continues to inspect the fabric.

[0004] The existing inspection equipment has the following drawbacks: First, when workers repair defects, the machine needs to be stopped, which affects the inspection efficiency of the fabric. Second, when the fabric is being inspected, workers need to wait for defects to appear before they can be repaired, resulting in idle and wasted labor. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of existing inspection devices, this invention proposes a fabric inspection device that reduces downtime, improves fabric inspection efficiency, and increases labor utilization.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A fabric inspection device includes a first fabric feeding mechanism, a second fabric feeding mechanism, an inspection marking mechanism, a first identifier, and a second identifier; The first fabric feeding mechanism and the second fabric feeding mechanism respectively transport the first fabric and the second fabric. The movement path of the first fabric includes the first fabric inspection section and the first fabric repair section set upstream and downstream. The movement path of the second fabric includes the second fabric inspection section and the second fabric repair section set upstream and downstream. The first fabric inspection section and the second fabric inspection section are located on the upper and lower sides of the fabric inspection marking mechanism, respectively. The inspection device includes a first operating mode and a second operating mode. In the first operating mode, the first fabric feeding mechanism operates, the second fabric feeding mechanism stops, and the fabric inspection and marking mechanism inspects the first fabric on the first inspection section and marks the defects. In the second operating mode, the second fabric feeding mechanism operates, the first fabric feeding mechanism stops, and the fabric inspection and marking mechanism inspects the second fabric on the second inspection section and marks the defects. When the inspection device is in the first operating mode or the second operating mode, the inspection device switches to the second operating mode when the first identifier detects the mark on the first repair section, and switches to the first operating mode when the second identifier detects the mark on the second repair section.

[0007] Furthermore, the fabric inspection and marking mechanism includes a lateral driver, a movable seat, a camera, a rotator, and a marker. The movable seat is located between the first fabric inspection section and the second fabric inspection section. The lateral driver drives the movable seat to reciprocate laterally. The camera and the marker are both mounted on the movable seat. The rotator is used to drive the camera to rotate up or down. The marker is used to mark the first fabric on the first fabric inspection section and the second fabric on the second fabric inspection section.

[0008] Furthermore, the marker includes a first electric push rod, a first nozzle, a first pump, a second electric push rod, a second nozzle, a second pump, and a material tank. The material tank contains pigment and is mounted on a movable base. The material tank is connected to the first nozzle via the first pump. The first nozzle faces the first inspection section. The first electric push rod is used to drive the first nozzle to move up and down. The material tank is connected to the second nozzle via the second pump. The second nozzle faces the second inspection section. The second electric push rod is used to drive the second nozzle to move up and down.

[0009] Furthermore, the lateral drive is configured as a linear motor, and the mover of the linear motor is connected to the moving base.

[0010] Furthermore, the first fabric feeding mechanism includes a first discharge roller, a first roller group, a first reversing roller and a first take-up roller arranged sequentially from upstream to downstream. One end of the first fabric is wound around the first discharge roller, and the other end of the first fabric is wound around the first take-up roller after passing through the first roller group and the first reversing roller. The first fabric inspection section is located between the first roller group and the first reversing roller, and the first fabric extends horizontally in the first fabric inspection section. The second fabric feeding mechanism includes a second discharge roller, a second roller group, a second reversing roller, and a second take-up roller arranged sequentially from upstream to downstream. One end of the second fabric is wound around the second discharge roller, and the other end of the second fabric is wound around the second take-up roller after passing through the second roller group and the second reversing roller. The second fabric inspection section is located between the second roller group and the second reversing roller, and the second fabric extends horizontally in the second fabric inspection section.

[0011] Furthermore, the first fabric feeding mechanism also includes a first support roller, a second support roller and a third support roller. The first fabric extends upward from the first reversing roller to the first support roller, horizontally from the first support roller to the second support roller, downward from the second support roller to the third support roller, and from the third support roller to the first take-up roller. The first trimming section is disposed between the second support roller and the third support roller. The second fabric feeding mechanism also includes a fourth support roller. The second fabric extends downward from the second reversing roller to the fourth support roller. The second fabric trimming section is located between the second reversing roller and the fourth support roller. The second fabric trimming section and the first fabric trimming section are arranged side by side. The first fabric extends from the fourth support roller away from the first fabric trimming section to the second take-up roller.

[0012] Furthermore, the inspection device also includes a first support, a second support, and a third support. The first discharge roller, the second discharge roller, and the second take-up roller are arranged sequentially from top to bottom and rotatably connected to the first support.

In this invention, when the worker is in the first operating mode of the inspection device, he repairs the defects on the second fabric repair section, and when the worker is in the second operating mode of the inspection device, he repairs the defects on the first fabric repair section, thereby improving labor utilization and reducing labor costs. 3. In this invention, the first and second repair sections are arranged side by side, which makes it convenient for workers to stand between them to repair defects and improves inspection efficiency.

[0020] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] like Figures 1 to 6 This invention proposes a fabric inspection device that can improve the efficiency of fabric inspection and reduce idle labor. The inspection device includes a first fabric feeding mechanism 3, a second fabric feeding mechanism 4, a fabric inspection marking mechanism 5, a first identifier 6, and a second identifier 7. The first fabric feeding mechanism 3 and the second fabric feeding mechanism 4 respectively transport the first fabric 8 and the second fabric 9. The structure of the first fabric feeding mechanism 3 and the second fabric feeding mechanism 4 is not limited for the time being. The movement path of the first fabric 8 includes the first fabric inspection section 10 and the first fabric repair section 11 set up upstream and downstream. That is, during the movement of the first fabric 8, it first passes through the first fabric inspection section 10 and then passes through the first fabric repair section 11. The movement path of the second fabric 9 includes the second fabric inspection section 12 and the second fabric repair section 13 set up upstream and downstream. That is, during the movement of the second fabric 9, it first passes through the second fabric inspection section 12 and then passes through the second fabric repair section 13. The first fabric inspection section 10 and the second fabric inspection section 12 are located on the upper and lower sides of the fabric inspection marking mechanism 5, respectively. The inspection device includes a first operating mode and a second operating mode. In the first operating mode, the first fabric feeding mechanism 3 operates, the second fabric feeding mechanism 4 stops, and the fabric inspection and marking mechanism 5 inspects the first fabric 8 on the first inspection section 10 and marks the defects on the first fabric 8 in the first inspection section 10. In the second operating mode, the second fabric feeding mechanism 4 operates, the first fabric feeding mechanism 3 stops, and the fabric inspection and marking mechanism 5 inspects the second fabric 9 on the second inspection section 12 and marks the defects. When the inspection device is in the first operating mode or the second operating mode, the inspection device switches to the second operating mode when the first identifier 6 identifies the mark on the first repair section 11, and switches to the first operating mode when the second identifier 7 identifies the mark on the second repair section 13.

[0022] When inspecting the fabric using the inspection device of this embodiment, the inspection device is in the first operating mode. The first fabric 8 moves forward under the drive of the first feeding mechanism 3. The fabric inspection marking mechanism 5 inspects the first fabric 8 located at the first inspection section 10. When a defect is detected in the first fabric 8, the fabric inspection marking mechanism 5 marks the defect. At this time, the inspection device still maintains the first operating mode. The first fabric 8 continues to move forward under the action of the first feeding mechanism 3. The fabric inspection marking mechanism 5 continues to inspect the first fabric 8 on the first inspection section 10. The mark made on the first inspection section 10 moves forward with the first fabric 8. The first identifier 6 can be an industrial camera to take real-time pictures of the first fabric 8 in the first repair section 11. Figure 5 When a mark 22 enters the field of view of the first identifier 6, the first fabric feeding mechanism 3 stops moving forward, the inspection device exits the first operating mode, the inspection device switches to the second operating mode, and begins to inspect the second fabric 9. Workers utilize the time gap when the inspection device exits the first operating mode and the first fabric 8 stops moving to repair defects on the first fabric 8 in the first repair section 11. After repair, the markings are removed. Before the repair is completed, the markings remain. If the first identifier 6 recognizes the markings, the inspection device cannot switch back to the first operating mode to prevent the first fabric 8 from moving prematurely while the worker is repairing defects. After the worker removes the markings, if the inspection device still has not exited the second operating mode, the inspection device continues to maintain the second operating mode. If the inspection device exits the second operating mode, it switches back to the first operating mode to continue inspecting the first fabric 8. In actual production, the second fabric 9 has fewer defects, and workers can generally complete the removal of defects and markings on the first fabric 8 in the first repair section 11 before the inspection device exits the second operating mode. When the inspection device inspects the second fabric 9 in the second operating mode, the second fabric 9 moves forward under the action of the second feeding mechanism 4, passing through the second inspection section 12 and the second repair section 13. When the second fabric 9 reaches the second inspection section 12, the inspection marking mechanism 5 checks the second fabric 9 in the second inspection section 12. When a defect is detected, the inspection marking mechanism 5 marks the defect. The mark on the second fabric 9 moves with the second fabric 9 to the second repair section 13. The second identifier 7 uses an industrial camera to take real-time pictures of the second fabric 9 in the second repair section 13. When the second identifier 7 identifies the mark on the second inspection section 12, the inspection device exits the second operating mode. Figure 6 ; Workers utilize the time gap when the inspection device exits the second operating mode and the second fabric 9 stops moving to repair defects on the second fabric 9 in the second repair section 13. After repair, the markings are removed. Before the repair is completed, the markings remain. If the second identifier 7 detects the markings, the inspection device cannot switch back to the second operating mode to prevent the second fabric 9 from moving prematurely while the worker is repairing defects. After the worker removes the markings on the second repair section 13, if the inspection device has not yet exited the first operating mode, the inspection device continues to maintain the first operating mode. If the inspection device exits the first operating mode, it switches back to the second operating mode to continue inspecting the second fabric 9. In actual production, the first fabric 8 has fewer defects, and workers can generally complete the removal of defects and markings on the second fabric 9 in the second repair section 13 before the inspection device exits the first operating mode. In this way, the inspection device can switch back and forth between the first and second operating modes to continuously inspect the fabric and improve inspection efficiency. When the inspection device is in the first operating mode, workers can repair the defects found in the second operating mode, and when the inspection device is in the second operating mode, workers can repair the defects found in the first operating mode, reducing idle labor and improving labor utilization.

[0023] In one embodiment, the fabric inspection and marking mechanism 5 includes a lateral driver 14, a movable base 15, a camera 16, a rotator 17, and a marker 18. The movable base 15 is disposed between the first fabric inspection section 10 and the second fabric inspection section 12. The lateral driver 14 drives the movable base 15 to reciprocate laterally, wherein the lateral direction is the width direction of the fabric. The camera 16 and the marker 18 are both mounted on the movable base 15, so that the camera 16 and the marker 18 can move synchronously with the movable base 15. The rotator 17 is used to drive the camera 16 to rotate upward or downward. The camera 16 is a vision system camera, which can detect and identify defects on the entire width of the fabric when it reciprocates laterally with the movable base 15. The rotator 17 can be a servo motor. When the rotator 17 drives the camera 16 downward, the camera 16 can identify defects in the second fabric 9 on the second inspection section 12. When the rotator 17 drives the camera 16 upward, the camera 16 can identify defects in the first fabric 8 on the first inspection section 10. The marker 18 is used to mark the first fabric 8 on the first inspection section 10 and the second fabric 9 on the second inspection section 12. Since the marker 18 and the camera 16 are both mounted on the moving base 15, the marker 18 and the camera 16 are relatively close. After the camera 16 captures a defect, the marker 18 can make a mark near the defect, which makes it convenient for workers to find the defect according to the mark and repair it.

[0024] In one embodiment, such as Figure 2 The marker 18 includes a first electric push rod 181, a first nozzle 182, a first pump (not shown in the figure), a second electric push rod 183, a second nozzle 184, a second pump (not shown in the figure), and a material tank 185. The material tank 185 holds the pigment and is mounted on the movable base 15. The pigment is either heat-dissolving or water-washable, making it easy to remove. The material tank 185 is connected to the first nozzle 182 via the first pump. The first nozzle 182 faces the first inspection section 10. The first electric push rod 181 is used to drive the first nozzle 182 to move up and down. The material tank 185 is connected to the second nozzle 184 via the second pump. The second nozzle 184 faces the second inspection section 12. The second electric push rod 183 is used to drive the second nozzle 184 to move up and down.

[0025] When marking the first greige fabric 8 on the first inspection section 10, the first electric push rod 181 extends, the first nozzle 182 moves upward and closer to the first greige fabric 8, the first pump pumps the pigment from the material tank 185 to the first nozzle 182, the first nozzle 182 sprays the pigment onto the first greige fabric 8, completing the marking, and the first electric push rod 181 retracts; when marking the second greige fabric 9 on the second inspection section 12, the second electric push rod 183 extends, as... Figure 4 The second nozzle 184 moves downwards towards the second fabric 9, the second pump pumps the pigment in the material tank 185 to the second nozzle 184, the second nozzle 184 sprays the pigment onto the second fabric 9 to complete the marking, and the second electric push rod 183 retracts.

[0026] In one embodiment, the lateral driver 14 is configured as a linear motor, and the mover of the linear motor is connected to the movable seat 15. With the above configuration, the movable seat 15 is driven to reciprocate laterally by the linear motor.

[0027] In one embodiment, such as Figure 1 The first fabric feeding mechanism 3 includes a first discharge roller 31, a first roller group 32, a first reversing roller 33, and a first take-up roller 34 arranged sequentially from upstream to downstream. One end of the first fabric 8 is wound around the first discharge roller 31. The first fabric 8 wound around the first discharge roller 31 is to be inspected. The other end of the first fabric 8 passes through the first roller group 32 and the first reversing roller 33 and is wound around the first take-up roller 34. The first take-up roller 34 is connected to a power source and can rotate to pull the first fabric 8 forward. The first inspection section 10 is located between the first roller group 32 and the first reversing roller 33. The first roller group 32 includes two parallel rollers arranged vertically. After the first fabric 8 passes through the first roller group 32, the first roller group 32 can prevent the first fabric 8 from moving up and down, so that the first fabric 8 is kept horizontally extended in the first inspection section 10, which is convenient for the inspection marking mechanism 5 to inspect. The second fabric feeding mechanism 4 includes a second discharge roller 41, a second roller group 42, a second reversing roller 43, and a second take-up roller 44 arranged sequentially from upstream to downstream. One end of the second fabric 9 is wound around the second discharge roller 41. The second fabric 9 wound around the second discharge roller 41 is to be inspected. The other end of the second fabric 9 passes through the second roller group 42 and the second reversing roller 43 and is wound around the second take-up roller 44. The second take-up roller 44 is connected to a power source and can rotate to pull the second fabric 9 forward. The second inspection section 12 is located between the second roller group 42 and the second reversing roller 43. The second roller group 42 includes two horizontal rollers arranged vertically. After the second fabric 9 passes through the second roller group 42, the second roller group 42 can prevent the second fabric 9 from moving up and down, so that the second fabric 9 remains horizontally extended in the second inspection section 12, which is convenient for the inspection and marking mechanism 5 to inspect.

[0028] In one embodiment, the first fabric feeding mechanism 3 further includes a first support roller 35, a second support roller 36 and a third support roller 37. The first fabric 8 extends upward from the first reversing roller 33 to the first support roller 35, extends horizontally from the first support roller 35 to the second support roller 36, extends downward from the second support roller 36 to the third support roller 37, and extends from the third support roller 37 to the first take-up roller 34. The first fabric trimming section 11 is disposed between the second support roller 36 and the third support roller 37. The second fabric feeding mechanism 4 also includes a fourth support roller 45. The second fabric 9 extends downward from the second reversing roller 43 to the fourth support roller 45. The second fabric trimming section 13 is located between the second reversing roller 43 and the fourth support roller 45. The second fabric trimming section 13 and the first fabric trimming section 11 are arranged side by side. The first fabric 8 extends from the fourth support roller 45 away from the first fabric trimming section 11 to the second take-up roller 44.

[0029] With the above setup, the first support roller 35 and the second support roller 36 raise the second fabric 9, making it easier for workers to stand between the first repair section 11 and the second repair section 13 to repair defects on the left side of the second repair section 13 and on the right side of the first repair section 11.

[0030] In one embodiment, the inspection device further includes a first support 19, a second support 20, and a third support 21. A first discharge roller 31, a second discharge roller 41, and a second take-up roller 44 are arranged sequentially from top to bottom and rotatably connected to the first support 19. A support plate is horizontally fixedly connected to the second support 20. A movable seat 15 is slidably connected to the support plate. A second identifier 7 is installed on the second support 20. The first take-up roller 34 is rotatably connected to the third support 21. A first identifier 6 is installed on the third support 21.
