Description

Technical Field

[0001] The present application relates to the technical field of label quality inspection equipment, and specifically to a quality inspection slitting machine with a label rejection function and a rejection method. Background Art

[0002] The label inspection and slitting machine is mainly used to slit and rewind the rolled labels after label production. The quality of the labels is tested during rewinding. When defective products are found, they need to be dealt with in a timely manner. The label inspection and slitting machine generally uses CCD to replace manual inspection of the label appearance. It adopts step-by-step motion and controls the CCD to take pictures through external triggering of the sensor. The computer software algorithm then determines OK and NG products, and the result of the capture is fed back to the PLC for processing. If it is determined to be OK, the equipment continues to move. If it is determined to be NG, the equipment automatically stops and an alarm is issued.

[0003] Regarding the above-mentioned related technologies, when the label inspection and slitting machine inspects the label, if the inspection result is judged to be NG, the equipment will automatically stop running and alarm. At this time, it is necessary to wait for manual verification. After verification, the product labels judged to be NG need to be processed manually. The efficiency of this process depends entirely on the manual response speed after the equipment alarm and the efficiency of handling defective products. Once the manual processing is not timely, the efficiency of label inspection will drop significantly, which will lead to low working efficiency of the label inspection and slitting machine, affecting the normal production process.

DETAILED DESCRIPTION

[0017] In order to better understand the above technical solution, Figure 1-10 And specific implementation methods are used to describe the above technical solutions in detail.

[0018] refer to Figure 1 and Figure 2The present application discloses a quality inspection and slitting machine with a label removal function, comprising a main unit 1, a material table 11, a first coil 12, a sticker 121 and a removal mechanism 2. The material table 11 is fixedly installed inside the main unit 1 and near the upper end, so that the visual inspection system can detect the quality of the labels on the first coil 12. The interior of the main unit 1 includes a roller, a winding mechanism, an unwinding mechanism and a stripping mechanism. The unwinding mechanism unwinds the first coil 12, and uses the roller to adjust the unfolding form of the first coil 12. The quality of the labels on the first coil 12 is inspected by the inspection system on the material table 11, and then the stripping mechanism is used to strip the first coil 12 as needed. Finally, the stripped first coil 12 is rewound by the winding mechanism. The first coil 12 is placed inside the main unit 1, and the defective labels on the first coil 12 are defined as stickers 121. The stickers 121 are affixed to the surface of the first coil 12. After unwinding the first coil 12, during the inspection and rewinding process, the unwound portion of the first coil 12 is laid on the upper end surface of the material table 11 near the center, and the sticker 121 is located on the upper end surface of the first coil 12. The rejection mechanism 2 is installed on the inner side of the main unit 1 near the material table 11 and is used to reject the sticker 121 on the surface of the first coil 12.

[0019] During operation, a first web 12 is placed in the main machine 1 for unwinding. During the unwinding process, the visual inspection system within the main machine 1 performs a quality inspection on the labels on the first web 12. During the inspection process, the first web 12 is laid on the material table 11 with the labels facing upward. Defective labels on the first web 12 are defined as stickers 121. If a sticker 121 appears during the inspection of the first web 12, the rejection mechanism 2 removes the sticker 121 from the first web 12. The first web 12, which has passed the quality inspection, is then striped and rewound again by the stripping mechanism within the main machine 1. This completes the quality inspection and stripping of the labels on the first web 12.

[0020] refer to Figures 2 to 8 The rejection mechanism 2 includes a dustproof housing 21, a second web 22, a rejection assembly 23, and a fixing assembly 25. The dustproof housing 21 is fixedly mounted on the inner side of the main unit 1 and close to the material table 11. The fixing assembly 25 is mounted inside the dustproof housing 21 and close to the material table 11. A corresponding number of fixing assemblies 25 are provided according to actual needs, so that the fixing assemblies 25 are distributed along the width direction of the material table 11. The number of fixing assemblies 25 is the same as the number of rows of labels on the first web 12. The rejection assembly 23 is mounted inside the dustproof housing 21 and close to the fixing assembly 25. The same number of rejection assemblies 23 is arranged according to the number of fixing assemblies 25. The second web 22 is mounted inside the dustproof housing 21 and close to the rejection assembly 23.

[0021] The reject assembly 23 includes a first side plate 231, a first roller 232, a second roller 233, an auxiliary roller 234, a driving roller 235, a supporting roller 236, a third roller 237, a fourth roller 238, a fifth roller 239, a crossbar 230, and a scraper unit 24. The scraper unit 24 is mounted on the inner side wall of the first side plate 231, near the material platform 11. The scraper unit 24 includes a light scraper 241, an insert 242, a fixing plate 243, a socket 245, a latch 247, a spring 248, and a sleeve 249. The sleeve 249 is fixedly mounted on the inner side wall of the first side plate 231, near the material platform 11. The spring 248 is inserted into the interior of the sleeve 249, and one end of the spring 248 is fixedly connected to the inner side wall of the first side plate 231. A latch 247 is fixedly mounted on the end of the spring 248 away from the first side plate 231. The end of the latch 247 that is fixedly connected to the spring 248 is inserted into the interior of the sleeve 249. The fixed plate 243 is mounted on the inner side of the first side plate 231, near the latch 247. Sockets 245 are fixedly mounted on both ends of the fixed plate 243, symmetrically distributed about the fixed plate 243. Sockets 245 are defined on the outer walls of the sockets 245 for receiving the latch 247. The end of the latch 247 away from the spring 248 is inserted into the socket 246 defined in the socket 245. A slot 244 is defined near the center of the fixed plate 243. The insert block 242 is inserted into the slot 244 in the fixed plate 243. The optical shovel 241 is fixedly mounted on the end of the insert block 242 away from the driving roller 235. The end of the optical shovel 241 away from the insert block 242 overlaps the side of the material table 11.

[0022] The first roller 232 is mounted on the inner side wall of the first side plate 231, and the two first side plates 231 are symmetrically distributed about the first roller 232. The first roller 232 is mounted on the inner side of the two first side plates 231 and is close to one end of the material platform 11. The second roller 233 is mounted on the other end of the inner side of the two first side plates 231. The second coil 22 is sleeved on the second roller 233, and the second coil 22 is rotatably connected to the second roller 233. The active roller 235 is mounted on the inner side wall of the first side plate 231 and is close to the scraper part 24. The active roller 235 has a built-in motor, and the active roller 235 is rotated by the drive shaft of the motor. The auxiliary roller 234 is rotatably mounted on the inner side wall of the first side plate 231 and is close to the active roller 235. The support roller 236 is mounted on the inner side wall of the first side plate 231 near the driving roller 235. The support roller 236 is meshed with the driving roller 235. When the driving roller 235 rotates, the support roller 236 and the driving roller 235 rotate synchronously. The third roller 237 is mounted on the inner side wall of the first side plate 231 near the support roller 236. The third roller 237 is also mounted on the inner side wall of the first side plate 231 near the second roller 233. The fourth roller 238 is mounted on the inner side wall of the first side plate 231 near the auxiliary roller 234. The fifth roller 239 is mounted on the inner side wall of the first side plate 231 near the fourth roller 238. The fifth roller 239 is also mounted on the inner side wall of the first side plate 231 near the first roller 232. The auxiliary roller 234 and the fourth roller 238 tend to fit together to clamp the unrolled surface material of the second coil 22. The cross bar 230 is fixedly mounted on the inner side wall of the first side plate 231 near the upper end, and the cross bar 230 is fixedly mounted on the inner side wall of the first side plate 231 near the second roller 233. The second coil 22 is unwound at the second roller 233, and one end of the unwound second coil 22 is wrapped around the outside of the third roller 237 from the bottom of the third roller 237, and then wrapped around the outside of the support roller 236 from the top of the supporting roller 236, and then wrapped around the outside of the auxiliary roller 234 from the top of the auxiliary roller 234. The auxiliary roller 234 and the fourth roller 238 clamp the second coil 22, and after extending from the fourth roller 238, it is wrapped around the outside of the fifth roller 239 from the top of the fifth roller 239, and finally fixed on the first roller 232. The first roller 232 rewinds the unwound part of the first coil 12.

[0023] Before quality inspection of the first coil 12, select the appropriate optical shovel 241 and second coil 22 based on the size of the label on the first coil 12. Insert the optical shovel 241 into the slot 244 on the fixing plate 243 via the insert 242. Then, secure the fixing plate 243 to the inner wall of the first side plate 231 by inserting the socket 245 and the latch 247. This completes the installation of the selected optical shovel 241. The second coil 22 is then placed on the second roller 233 and unwound at the second roller 233. One end of the unwound and unfolded second coil 22 is wrapped around the outside of the third roller 237 from the bottom of the third roller 237, and then wrapped around the outside of the support roller 236 from the top of the supporting roller 236, and then wrapped around the outside of the auxiliary roller 234 from the top of the auxiliary roller 234. The auxiliary roller 234 and the fourth roller 238 clamp the second coil 22, and after extending from the fourth roller 238, it is wrapped around the outside of the fifth roller 239 from the top of the fifth roller 239, and finally fixed on the first roller 232. The first roller 232 rewinds the unwound part of the first coil 12. After the motor at the active roller 235 is started, the active roller 235 rotates, causing the active roller 235 to drive the supporting roller 236 to rotate, thereby driving the second coil 22 to unwind and rewind. During the quality inspection of the first web 12, if a sticker 121, identified as a defective label, appears on the first web 12, the optical shovel 241 is positioned in the gap between the surface material of the first web 12 and the sticker 121. The front end of the optical shovel 241 removes the sticker 121 from the surface material of the first web 12. As the first web 12 continues to move, the sticker 121 moves along the optical shovel 241 toward the active roller 235 and gradually detaches from the first web 12. The rotation of the active roller 235 drives the sticker 121 toward the second web 22. As the second web 22 continues to move, the sticker 121 adheres to the surface of the second web 22 after the front end of the sticker 121 contacts it. The sticker 121 then moves toward the auxiliary roller 234. The auxiliary roller 234 and the fourth roller 238 clamp the second web 22, squeezing the sticker 121 and the second web 22 against each other and adhering the sticker 121 to the surface of the second web 22. As the active roller 235 rotates, the second web 22 with the sticker 121 is wound around the first roller 232.

[0024] refer to Figure 3 、 Figure 5 、 Figure 9 and Figure 10The fixing assembly 25 includes a fixing beam 251, a second side plate 252 and a propulsion portion 26. The fixing beam 251 is fixedly mounted on the inner side wall of the dustproof housing 21 and is close to the first side plate 231. The second side plate 252 is fixedly mounted at both ends of the fixing beam 251 and is close to the first side plate 231, and the two second side plates 252 are symmetrically distributed about the fixing beam 251. A mounting through hole 253 is provided on the inner side wall of the second side plate 252 and is close to the fixing beam 251. Both ends of the first roller 232 pass through the first side plate 231 and extend to the outside of the first side plate 231. The portion of the first roller 232 that passes through the outside of the first side plate 231 is inserted into the mounting through hole 253 provided on the second side plate 252. The first roller 232 is rotatably connected to the second side plate 252. A curved slot 254 is defined on the inner sidewall of the second side plate 252, near the second roller 233. Both ends of the second roller 233 extend through the first side plate 231 and outward from the first side plate 231. The portion of the second roller 233 that extends outward from the first side plate 231 is inserted into the curved slot 254 defined on the second side plate 252, where the second roller 233 slides. The second roller 233 moves in a circular motion within the curved slot 254, centered around the first roller 232. The propulsion unit 26 is mounted on the fixed beam 251.

[0025] The propulsion unit 26 includes an electric push rod 261, a first connecting rod 262, a second connecting rod 263, a third connecting rod 264 and a middle rotating rod 265. One end of the base of the electric push rod 261 is fixedly mounted on the fixed beam 251 on the inner side of the second side plate 252. The first connecting rod 262 is fixedly mounted at the traveling end of the electric push rod 261. The second connecting rod 263 is rotatably mounted at both ends of the first connecting rod 262, and the second connecting rods 263 at both ends of the first connecting rod 262 are symmetrically distributed about the electric push rod 261. The middle rotating rod 265 is fixedly mounted on the inner side wall of the second side plate 252 and close to the second connecting rod 263. A plug-in hole is provided on the second connecting rod 263 near the first connecting rod 262. The middle rotating rod 265 is inserted into the plug-in hole on the second connecting rod 263, and the second connecting rod 263 is rotatably connected to the middle rotating rod 265. The third connecting rod 264 is rotatably mounted on the lower end of the second connecting rod 263 , and the lower end of the third connecting rod 264 is rotatably connected to the cross bar 230 .

[0026] The fixing assembly 25 is used to secure the rejection assembly 23 and control its lowering and return to its original position. When a sticker 121 appears on the first web 12, the corresponding electric push rod 261 extends, pushing the first connecting rod 262 forward. This displacement of the first connecting rod 262 causes the second connecting rod 263 to swing, with the middle rotating rod 265 serving as the fulcrum. The third connecting rod 264 at the lower end of the second connecting rod 263 moves with the swing of the second connecting rod 263, pushing the crossbar 230 located inside the first side plate 231 to move. As the crossbar 230 moves, the second roller 233 slides within the curved chute 254, performing a circular motion around the first roller 232. At this point, the first side plate 231 rotates around the first roller 232. The optical shovel 241 is then placed over the upper surface of the first web 12 on the material table 11, allowing it to smoothly insert between the first web 12 and the sticker 121, allowing it to remove the sticker 121 from the first web 12. After the rejection assembly 23 completes its operation, the electric push rod 261 returns to its original position. Simultaneously, the second and third connecting rods 263 and 264 return to their original positions, causing the second roller 233 to return from the lower end of the curved chute 254 to its upper end. The optical shovel 241 is now free from contact with the surface of the first web 12.

[0027] A label removal method for a product inspection and slitting machine with a label removal function, comprising the following steps: S1. Assemble the materials. Select a suitable blade and insert it into the fixed plate 243. Then, fix the fixed plate 243 between the two first side plates 231. Place the selected second coil 22 on the second roller 233 and fix the unrolled end of the second coil 22 to the first roller 232. S2. Defective products are removed. When the sticker 121 with a defective label moves to below the first side plate 231 on one side of the material table 11, the travel end of the electric push rod 261 pushes the first connecting rod 262 to move. With the help of the second connecting rod 263, the optical shovel 241 swings to the upper end surface of the first web 12. The front end of the optical shovel 241 is inserted between the sticker 121 and the first web 12, and the sticker 121 is lifted and removed from the surface of the first web 12. S3. Defective products are collected. The rotation of the active roller 235 drives the sticker 121 to continue moving. The front end of the sticker 121 contacts the surface of the second web 22. The displacement of the second web 22 drives the sticker 121 toward the auxiliary roller 234. The auxiliary roller 234 adheres the sticker 121 to the surface of the second web 22, and the sticker 121 is collected and reeled. S4. The mechanism is reset. After the selected defective stickers 121 are completely removed from the first web 12, the electric push rod 261 is reset, thereby resetting the first side plate 231 and the optical shovel 241. The active roller 235 stops rotating. At this time, the second web 22 stops unwinding and rewinding. The rejection mechanism 2 is in standby mode again, waiting to remove the subsequent defective label stickers 121 on the first web 12.

[0028] The working principle of the embodiment of this application: A matching optical shovel 241 and second web 22 are selected based on the specifications of the first web 12. The optical shovel 241 is secured to the fixing plate 243 by connecting the insert 242 with the slot 244. The fixing plate 243 is then secured to the inside of the first side panel 231 by connecting the socket 245 with the latch 247. The second web 22 is then installed inside the first side panel 231. When a sticker 121 labeled as defective appears on the first web 12, the moving end of the electric push rod 261 pushes the first connecting rod 262 to move. The rotation of the second connecting rod 263 causes the third connecting rod 264 to push the crossbar 230 to move, thereby moving the second roller 233 from the upper end of the curved chute 254 to the lower end. The optical shovel 241 is attached to the surface of the first web 12 and removes the stickers 121 from the first web 12. The second web 22 is unwound and rewound by means of the active roller 235 and the support rotation. The stickers 121 between the active roller 235 and the auxiliary roller 234 are then attached to the surface of the second web 22 by means of the auxiliary roller 234, thereby collecting the stickers 121. The stickers 121 are then rewound by rewinding the second web 22.
