Description

Technical Field

[0001] This invention relates to a digital device for automatic error correction and early warning during towel label sewing, belonging to the field of towel production technology. Background Technology

[0002] Towels are everyday cleaning products. They are made from three systems of yarns interwoven together to form a looped fabric. These three systems are the pile warp, the ground warp, and the weft. To standardize towel production, labels are usually sewn onto the edge of the towel. With the advancement of technology, the barcodes on the labels have been replaced by QR codes, which can carry more information, such as the towel's pattern. Labels also include traditional washing instructions.

[0003] For example, the Chinese utility model patent entitled "A Label Cutting Device for Towel Textiles" with publication number CN216006403U can make the cut labels uniform in size, but it lacks further identification and error correction of the labels. It still requires manual inspection and judgment, and then sorting out the errors. The process is repeated and easy to cause worker errors, and the efficiency is also low. Summary of the Invention

[0004] The purpose of this invention is to provide a digital device for automatic error correction and early warning in towel label sewing in order to solve the above problems. It can automatically identify the corresponding washing labels and QR code labels of towels and realize automatic error correction.

[0005] This invention achieves the above-mentioned objective through the following technical solution: a digital device for automatic error correction and early warning in towel label sewing, comprising a conveyor belt mechanism, a moving component, and an angle adjustment device. The conveyor belt mechanism can transfer the position of the towel. Under normal conditions, the conveyor belt mechanism transports the towel towards the moving component and the angle adjustment device. The towel originates from the label sewing mechanism, therefore the conveyor belt mechanism can also return the towel in the opposite direction. The moving component and the angle adjustment device are both located above the conveyor belt mechanism. The angle adjustment device can adjust the angle of the towel, i.e., rotate the towel. The specific rotation angle depends on the recognition of the vision inspection device. The angle adjustment device includes a base plate, a first lifting rod, a mounting plate, an adjustment motor, and an adjustment disc. The first lifting rod is fixed to the upper surface of the base plate, and one end of the first lifting rod extends to the lower part of the base plate. The mounting plate is fixed to the bottom end of the first lifting rod. The adjustment motor is fixed to the mounting plate, and the adjustment disc is fixed to the output shaft of the adjustment motor. The moving component is equipped with a vision inspection device, which is existing technology and capable of inspecting the towel... The system performs visual recognition on the labels, reads the label information, and then identifies the towel pattern accordingly. If the label is read incorrectly or there is no label, an alarm can be sent to the upper-level control system. The upper-level control system can be a single-chip microcomputer control system commonly used in digital equipment, which will not be described in detail here. The moving component is fixed to one side of the angle adjustment device. The moving component can sort and move the towels laterally. The moving component includes a second lifting rod, a housing, a moving belt, and a resistance device. The second lifting rod is fixed on the base plate, and the housing is fixed to the bottom end of the second lifting rod. The moving belt is installed in the housing through a roller rotation. The resistance device is fixed on the moving belt. A power motor for driving the moving belt is provided outside the housing. Support feet are provided on both sides of the angle adjustment device to support the angle adjustment device and the moving component. A winding mechanism is installed on the conveyor belt mechanism to wind up towels that meet the standards for packaging and collection. The visual inspection instrument, the moving component, the angle adjustment device, and the winding mechanism are arranged in sequence. A power connector is provided on one side of the conveyor belt mechanism through a power cord.

[0006] Preferably, in order to better secure the towel and move the towel as a whole, the output shaft of the adjusting motor extends to the bottom of the mounting plate, the adjusting disc has a hollow structure, an adsorption port is provided at the bottom of the adjusting disc, a negative pressure interface is provided on the upper surface of the adjusting disc, and an opening is provided on the base plate above the adjusting motor.

[0007] Preferably, for a more complete and stable positioning of the moving towel, the resistance device includes a base, a plate, and a nylon brush. The plate is fixed to the base, and the nylon brush is fixed to the plate. Alternatively, the resistance device includes a base, a flexible plate, and a tension spring. One end of the tension spring is fixed to the moving belt, the base is distributed on both sides of the tension spring, both sides of the flexible plate are fixed to the base, and the other end of the tension spring is fixed to the bottom of the flexible plate. The top of the flexible plate has a rough surface, which can be a rubber strip surface or a nylon brush surface.

[0008] Preferably, in order to automatically roll up the towel and facilitate easy detachment, the winding mechanism includes a horizontal steering device, a side plate, a winding motor, a negative pressure cylinder, and a fixing mechanism. The horizontal steering device is bolted to the conveyor belt mechanism and is used to rotate the position of the negative pressure cylinder, which can rotate horizontally. The side plate is mounted on the horizontal steering device. The winding motor is fixed to one side of the side plate, and the negative pressure cylinder is mounted on the other side of the side plate. The first end of the negative pressure cylinder extends to the same side as the winding motor. The fixing mechanism is installed inside the negative pressure cylinder. The first end of the negative pressure cylinder is provided with an air extraction connector. The output shaft of the winding motor and the first end of the negative pressure cylinder are meshed by teeth. The negative pressure cylinder has a winding opening. The fixing mechanism includes a slanted hook, a blocking plate, and a return spring. The slanted hook is fixed to the blocking plate. The outer wall of the negative pressure cylinder has a movable opening that allows the blocking plate to pass through. One end of the return spring is fixed to the inner wall of the negative pressure cylinder, and the other end of the return spring is fixed to the blocking plate. One end of the blocking plate is located inside the movable opening.

[0009] The beneficial effects of this invention are: by using a visual inspection device to identify the patterns, QR codes, and labels of towels, the quality standards of towels are improved, alarm notifications are issued in a timely manner, and towels can be sorted and reworked. The moving component can sort towels by distinguishing them from both sides.

[0010] The angle adjustment device can also adjust the angle of the towel. The adjustment plate can hold the towel up completely, preventing the towel from twisting.

[0011] The winding mechanism can automatically roll up the towel without manual operation. The negative pressure cylinder can absorb the towel, and the fixing mechanism can help fix the towel. The inclined hook can facilitate the release of the towel roll after winding is completed. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-7As shown, a digital device for automatic error correction and early warning in towel label sewing includes a conveyor belt mechanism 1, a moving component 2, and an angle adjustment device 3. The conveyor belt mechanism 1 can transfer the position of the towel. Under normal conditions, the conveyor belt mechanism 1 transports the towel towards the moving component 2 and the angle adjustment device. The towel originates from the label sewing mechanism, so the conveyor belt mechanism 1 can also return the towel in the opposite direction. The moving component 2 and the angle adjustment device 3 are both located above the conveyor belt mechanism 1. The angle adjustment device 3 can adjust the angle of the towel, i.e., rotate the towel. The specific rotation angle depends on the recognition of the vision inspection device 4. The angle adjustment device 3 includes a base plate 301, a first lifting rod 302, a mounting plate 303, and an adjustment motor 304. The adjustment disc 305 and the first lifting rod 302 are fixed on the upper surface of the base plate 301, with one end of the first lifting rod 302 extending to the bottom of the base plate 301. The mounting plate 303 is fixed on the bottom end of the first lifting rod 302. The adjustment motor 304 is fixed on the mounting plate 303, and the adjustment disc 305 is fixed on the output shaft of the adjustment motor 304. The moving assembly 2 is equipped with a vision inspection instrument 4. The vision inspection instrument 4 is existing technology and can visually recognize the labels on the towels, read the label information, and then identify the corresponding patterns of the towels. If the label is read incorrectly or there is no label, it can send an alarm to the upper-level control system. The upper-level control system can be a single-chip microcomputer control system commonly used in digital equipment, which will not be described in detail here. Component 2 is fixed to one side of the angle adjustment device 3. The moving component 2 can sort and laterally move towels. The moving component 2 includes a second lifting rod 201, a housing 202, a moving belt 203, and a resistance device 204. The second lifting rod 201 is fixed on the base plate 301, and the housing 202 is fixed to the bottom end of the second lifting rod 201. The moving belt 203 is installed inside the housing 202 by rotating a roller. The resistance device 204 is fixed on the moving belt 203. A power motor for driving the moving belt 203 is provided outside the housing 202. In use, when the visual inspection instrument 4 detects that the label is damaged or does not match the pattern, the moving component 2 can sort the corresponding towels. Specifically, the second lifting rod 201 drives the moving belt 203 on the housing 202 to descend. Then, it stops at a suitable position. The power motor drives the resistance device 204 on the moving belt 203 to rotate until the resistance device 204 pulls the towel out. In actual use, different towel defects are sorted separately on the left and right sides. When the lateral position of the towel needs to be adjusted, the resistance device 204 is pressed on the towel, and then the moving belt 203 is rotated to achieve fine adjustment of the towel's position. The angle adjustment device 3 has support feet on both sides to support the angle adjustment device 3 and the moving component 2. The angle adjustment device 3 can adjust the angle of the towel so that the winding mechanism 5 can wind it up. It can also adjust the position of the towel so that the conveyor belt mechanism 1 sends the towel back in the opposite direction for re-sewing the label. The winding mechanism 5 is installed on the conveyor belt mechanism 1.The winding mechanism 5 is used to wind up towels that meet the standards for packaging and collection. The vision inspection device 4, the moving component 2, the angle adjustment device 3, and the winding mechanism 5 are arranged in sequence. A power connector is provided on one side of the conveyor belt mechanism 1 via a power cord; the power connector is connected to an external power source during use.

[0022] like Figure 2 As shown, the output shaft of the adjusting motor 304 extends to the bottom of the mounting plate 303. The adjusting disc 305 has a hollow structure inside. The bottom of the adjusting disc 305 has an adsorption port, and the upper surface of the adjusting disc 305 has a negative pressure interface. The base plate 301 above the adjusting motor 304 has an opening. The angle adjusting device 3 can adjust the angle of the towel so that the winding mechanism 5 can wind it up. It can also adjust the position of the towel so that the conveyor belt mechanism 1 sends the towel back in the opposite direction for re-sewing the label. Specifically, the first lifting rod 302 drives the base plate 301 to descend, thereby causing the adjusting disc 305 to descend. Then, the negative pressure source and the negative pressure interface need to be connected. When the adjusting disc 305 is close to the towel, it can be adsorbed under the adjusting disc 305. Then, the adjusting motor 304 can drive the adjusting disc 305 to rotate, thereby adjusting the angle of the towel.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, the resistance device 204 includes a base 2041, a plate 2042, and a nylon brush 2043. The plate 2042 is fixed on the base 2041, and the nylon brush 2043 is fixed on the plate 2042. Alternatively, the resistance device 204 includes a base 2044, a flexible plate 2045, and a tension spring 2046. One end of the tension spring 2046 is fixed on the moving belt 203. The base 2044 is distributed on both sides of the tension spring 2046. Both sides of the flexible plate 2045 are fixed on the base 2044, and the other end of the tension spring 2046 is fixed to the bottom of the flexible plate 2045. The top of the flexible plate 2045 is provided with a rough surface, which can be the surface of a rubber strip or the surface of the nylon brush 2043.

[0024] like Figure 6 and Figure 7As shown, the winding mechanism 5 includes a horizontal steering device 501, a side plate 502, a winding motor 503, a negative pressure cylinder 504, and a fixing mechanism 505. The horizontal steering device 501 is bolted to the conveyor belt mechanism 1 and is used to rotate the position of the negative pressure cylinder 504, enabling horizontal rotation. The side plate 502 is mounted on the horizontal steering device 501, and the winding motor 503 is fixed to one side of the side plate 502. The negative pressure cylinder 504 is mounted on the side plate 502. On the other side, the first end of the negative pressure cylinder 504 extends to the same side as the winding motor 503. A fixing mechanism 505 is installed inside the negative pressure cylinder 504. The first end of the negative pressure cylinder 504 is equipped with an air extraction connector. The output shaft of the winding motor 503 and the first end of the negative pressure cylinder 504 are meshed by teeth. A winding opening is provided on the negative pressure cylinder 504. The fixing mechanism 505 includes a hook 5051, a blocking plate 5052, and a return spring 5053. The hook 5051 is fixed to the blocking plate 5052. The negative pressure cylinder 504... The outer wall of the negative pressure cylinder 504 has a movable opening that allows the blocking plate 5052 to pass through. One end of the return spring 5053 is fixed to the inner wall of the negative pressure cylinder 504, and the other end of the return spring 5053 is fixed to the blocking plate 5052. One end of the blocking plate 5052 is located inside the movable opening. The horizontal steering device 501 can move the negative pressure cylinder 504 above the conveyor belt mechanism 1, so that the negative pressure cylinder 504 is close to the towel. In use, it is necessary to connect the external negative pressure air source and the air extraction connector, and then the gas passes through the winding... An inlet is introduced, thereby adsorbing the towel onto the outer wall of the negative pressure cylinder 504. Since the negative pressure cylinder 504 is cylindrical, the fixing mechanism 505 can further facilitate the fixing of the towel. When in use, the inclined hook 5051 can hook the towel, increasing the friction to facilitate rolling. When it is necessary to remove the towel, the towel can press the inclined hook 5051 under the pulling action, and then the blocking plate 5052 will descend into the negative pressure cylinder 504. After the towel is removed, the return spring 5053 can drive the blocking plate 5052 to return to its original position.

[0025] In use, the power connector is connected to an external power source. After the towel is tagged, it is conveyed by the conveyor belt mechanism 1 to the area below the vision inspection device 4. The vision inspection device 4 is existing technology and can visually recognize the towel tags, read the tag information, and then identify the towel's pattern. If the tag is read incorrectly or there is no tag, an alarm is sent to the upper control system. The moving component 2 can sort the corresponding towels. Specifically, the second lifting rod 201 drives the moving belt 203 on the housing 202 to descend and then stop at a suitable position. The power motor drives the resistance device 204 on the moving belt 203 to rotate until the resistance device 204 pulls the towel out. In actual use, different towel defects are addressed. The towels are sorted separately on the left and right sides. The angle adjustment device 3 can adjust the angle of the towels so that the winding mechanism 5 can wind them up. It can also adjust the position of the towels so that the conveyor belt mechanism 1 can send the towels back in the opposite direction for re-sewing labels. Specifically, the first lifting rod 302 drives the base plate 301 to descend, which in turn causes the adjustment plate 305 to descend. Then, the negative pressure source and the negative pressure interface need to be connected. When the adjustment plate 305 is close to the towel, it can be attracted to the bottom of the adjustment plate 305. Then, the adjustment motor 304 can drive the adjustment plate 305 to rotate, thereby adjusting the angle of the towel. When the lateral position of the towel needs to be adjusted, the resistance device 204 is pressed on the towel, and then the moving belt 203 is driven to rotate to achieve fine adjustment of the towel's position.

[0026] The horizontal steering device 501 can move the negative pressure cylinder 504 above the conveyor belt mechanism 1, so that the negative pressure cylinder 504 is close to the towel. When in use, the external negative pressure air source and the air extraction connector need to be connected. Then the gas is introduced through the winding port, thereby adsorbing the towel onto the outer wall of the negative pressure cylinder 504. Since the negative pressure cylinder 504 is cylindrical, the fixing mechanism 505 can further facilitate the fixing of the towel. When in use, the inclined hook 5051 can hook the towel, increasing the friction to facilitate winding. When it is necessary to remove the towel, the towel can press the inclined hook 5051 under the pulling action, and then the blocking plate 5052 will descend into the negative pressure cylinder 504. After the towel is removed, the return spring 5053 can drive the blocking plate 5052 to return to its original position.

[0027] This invention uses a visual inspection device 4 to identify the patterns, QR codes, and labels on towels, improving towel quality standards, providing timely alarm notifications, and enabling towel sorting and reprocessing. The moving component 2 can sort towels by side and adjust their angle. The winding mechanism 5 automatically rolls up the towels without manual operation. The negative pressure cylinder 504 absorbs the towels, and the fixing mechanism 505 helps to fix the towels. The inclined hook 5051 facilitates the release of the towel roll after winding.
