Description

Technical Field

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

[0002] Label inspection and slitting machines are mainly used to slit and rewind rolls of labels after production. During rewinding, the quality of the labels is inspected, and defective products are promptly processed. Label inspection and slitting machines typically use CCDs to replace manual inspection of the label appearance. They employ a stepping motion, with external sensors triggering the CCD to capture images. Computer software algorithms then determine whether the products are OK or NG, feeding the captured results back to the PLC for processing. If OK, the machine continues; if NG, it automatically stops and triggers an alarm.

[0003] Regarding the aforementioned technologies, when a label inspection and slitting machine detects a label and the result is deemed NG (Not Good), the equipment will automatically stop operating and issue an alarm. At this point, manual verification is required. After verification, manual processing of the NG product labels is necessary. The efficiency of this process depends entirely on the speed of manual response to the alarm and the efficiency of processing defective products. If manual processing is not timely, the efficiency of label inspection will drop significantly, leading to low working efficiency of the label inspection and slitting machine and affecting the normal production process. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this application provides a quality inspection slitting machine with label rejection function, comprising a main unit for inspecting a first roll of material.

[0007] Furthermore, the shovel part includes a smooth shovel, and the smooth shovel has an insert block on the side near the active rotating roller. A fixing plate is provided on the inner side of the first side plate near the insert block. A slot is opened on the fixing plate near the insert block, and the insert block is inserted into the slot on the fixing plate.

[0008] Furthermore, the fixing plate has sockets at both ends, and the socket has a hole at the end near the first side plate. A sleeve is provided on the inner side wall of the first side plate near the socket. A spring is provided inside the sleeve, and a pin is provided at one end of the spring. The pin is inserted into the hole on the socket.

[0009] Furthermore, a fixing assembly is provided on the outer side of the first side plate. The fixing assembly includes a fixing beam, and a pushing part is provided on the fixing beam. Two second side plates are provided at both ends of the fixing beam, which are symmetrically distributed about the fixing beam. The second side plates are located on the outer side of the first side plate. An installation through hole is provided on the inner side wall of the second side plate near the first roller. The first roller is inserted into the installation through hole. A curved groove is provided on the inner side wall of the second side plate near the second roller. The second roller is inserted into the curved groove and is slidably connected to the curved groove.

[0010] Furthermore, the propulsion unit includes an electric push rod fixed to a fixed beam. The traveling end of the electric push rod is provided with a first connecting rod, and the two ends of the first connecting rod are provided with second connecting rods. A central rotating rod is provided on the inner side wall of the second side plate near the second connecting rod. The second connecting rod is rotatably connected to the central rotating rod. A third connecting rod is provided at the lower end of the second connecting rod. The third connecting rod is rotatably connected to the second connecting rod. A crossbar is provided on the inner side wall of the first side plate near the third connecting rod. The crossbar is inserted into the lower end of the third connecting rod and is rotatably connected to the third connecting rod.

[0011] A label rejection method for a quality inspection slitting machine with label rejection function, based on the above, includes the following steps:

[0012] S1. Material assembly: Select a suitable shovel and insert it into the fixing plate, then fix the fixing plate between the two first side plates, put the selected second roll on the second roller, and fix the unfolded end of the second roll on the first roller.

[0013] S2. Defective product rejection: When the sticker of the defective label moves to the bottom of the first side plate on one side of the material table, the traveling end of the electric push rod pushes the first connecting rod to move. With the help of the second connecting rod, the light shovel is swung to the upper end of the first roll, so that the front end of the light shovel is inserted between the sticker and the first roll, lifting the sticker and removing the sticker from the surface of the first roll.

[0014] S3. Defective product collection: The rotation of the active roller will drive the sticker to continue moving. The front end of the sticker will contact the surface of the second roll. The displacement of the second roll will drive the sticker to move towards the auxiliary roller. The auxiliary roller will be used to stick the sticker to the surface of the second roll. The sticker will be collected and rolled up.

[0015] S4. Mechanism reset: After the selected defective stickers are completely removed from the first roll, the electric push rod resets, which in turn resets the first side plate and the light scraper. The active roller stops rotating. At this time, the second roll stops unwinding and rewinding. The rejection mechanism is back in standby mode, waiting to remove subsequent defective labels from the first roll.

[0016] The technical solution provided in this application has the following advantages compared with the known prior art:

[0017] 1. This application, by setting up a rejection component, uses a second rotating roller and a first rotating roller to unwind the second roll of material, uses a scraper to remove the sticker from the first roll of material, and then uses an active rotating roller and an auxiliary rotating roller to stick the sticker onto the surface of the second roll of material for collection. This achieves automatic rejection and collection of defective products during the label inspection process, saving the time consumed by waiting for manual re-inspection and rejection, and improving the efficiency of label inspection.

[0018] 2. This application uses a fixing component to fix the first side plate with the second side plate, and a pushing part to control the position of the crossbar, so that the rejection component can swing inside the second side plate. This allows the light scraper to quickly switch between the state of being attached to the first roll and the state of being away from the first roll, improving the success rate of the rejection component in removing stickers. At the same time, the third connecting rod is used to fix the crossbar, reducing the possibility of the first side plate swinging unexpectedly during operation, and improving the success rate of the rejection component in removing stickers.

[0019] 3. This application sets up a scraper section and a plug at the tail of the scraper. By inserting the plug into the fixing plate and then using a socket to snap the fixing plate into the pin on the inside of the first side plate, the scraper can be installed and removed. The scraper model can be selected according to the size of the sticker on the first roll, improving the matching between the scraper and the sticker, and thus improving the efficiency of the scraper in removing the sticker.

[0031] To better understand the above technical solution, the following will refer to the appendix to the instruction manual. Figure 1-10 The specific implementation methods are described in detail below for the above technical solutions.

[0032] refer to Figure 1 and Figure 2 This application discloses a quality inspection slitting machine with label rejection function, including a main unit 1, a material table 11, a first roll 12, stickers 121, and a rejection mechanism 2. The material table 11 is fixedly installed inside the main unit 1 and near the top, facilitating the visual inspection system to inspect the label quality on the first roll 12. The main unit 1 includes a rotating roller, a winding mechanism, an unwinding mechanism, and a slitting mechanism. The unwinding mechanism unwinds the first roll 12, adjusts the unfolding shape of the first roll 12 using the rotating roller, and inspects the label quality on the first roll 12 using the inspection system on the material table 11. Then, the slitting mechanism slits the first roll 12 as needed, and finally, the winding mechanism rewinds the slitted first roll 12. The first roll 12 is placed inside the main unit 1, and the defective labels on the first roll 12 are defined as stickers 121, which are affixed to the surface of the first roll 12. After the first roll 12 is unwound, during the inspection and rewinding process, the unfolded portion of the first roll 12 will be laid on the upper surface of the material table 11 near the center, and the sticker 121 will be located on the upper surface of the first roll 12. The rejection mechanism 2 is installed inside the main unit 1 and near the material table 11, and is used to reject the sticker 121 on the surface of the first roll 12.

[0033] During operation, the first roll 12 is placed inside the main unit 1 for unwinding. During unwinding, the vision inspection system inside the main unit 1 performs quality inspection on the labels on the first roll 12. The first roll 12 is laid on the material table 11 with the labels facing upwards during inspection. Defective labels on the first roll 12 are defined as stickers 121. When stickers 121 are found during the inspection of the first roll 12, the rejection mechanism 2 removes the stickers 121 from the first roll 12. The first roll 12, after quality inspection, is then slit and rewound by the slitting mechanism inside the main unit 1. This completes the quality inspection and slitting process for the labels on the first roll 12.

[0034] refer to Figures 2 to 8 The rejection mechanism 2 includes a dustproof housing 21, a second roll of material 22, rejection components 23, and fixing components 25. The dustproof housing 21 is fixedly installed inside the main unit 1, near the material table 11. The fixing components 25 are installed inside the dustproof housing 21, near the material table 11. A corresponding number of fixing components 25 are set according to actual needs, distributing them along the width of the material table 11. The number of fixing components 25 is the same as the number of rows of labels on the first roll of material 12. The rejection components 23 are installed inside the dustproof housing 21, near the fixing components 25, and the same number of rejection components 23 are arranged according to the number of fixing components 25. The second roll of material 22 is installed inside the dustproof housing 21, near the rejection components 23.

[0035] The rejection assembly 23 includes a first side plate 231, a first rotating roller 232, a second rotating roller 233, an auxiliary rotating roller 234, a driving rotating roller 235, a support rotating roller 236, a third rotating roller 237, a fourth rotating roller 238, a fifth rotating roller 239, a crossbar 230, and a scraper section 24. The scraper section 24 is mounted on the inner wall of the first side plate 231, near the material platform 11. The scraper section 24 includes a smooth scraper 241, an insert block 242, a fixing plate 243, a socket 245, a pin 247, a spring 248, and a sleeve 249. The sleeve 249 is fixedly mounted on the inner wall of the first side plate 231, near the material platform 11. The spring 248 is inserted into the inside of the sleeve 249, and one end of the spring 248 is fixedly connected to the inner wall of the first side plate 231. A pin 247 is fixedly installed at the end of the spring 248 away from the first side plate 231, and the end of the pin 247 fixedly connected to the spring 248 is inserted into the inside of the sleeve 249. A fixing plate 243 is installed on the inner side of the first side plate 231 near the pin 247. Sockets 245 are fixedly installed at both ends of the fixing plate 243, and the sockets 245 at both ends are symmetrically distributed about the fixing plate 243. A socket hole 246 for inserting the pin 247 is provided on the outer wall of the socket 245. The end of the pin 247 away from the spring 248 is inserted into the socket hole 246 on the socket 245. A slot 244 is provided on the fixing plate 243 near the center. A plug 242 is inserted into the slot 244 on the fixing plate 243. A polishing shovel 241 is fixedly installed at the end of the plug 242 away from the drive roller 235. The end of the polishing shovel 241 away from the plug 242 overlaps the side of the material table 11.

[0036] The first roller 232 is mounted on the inner 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 near 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 roll 22 is sleeved on the second roller 233 and is rotatably connected to the second roller 233. The active roller 235 is mounted on the inner wall of the first side plate 231 and near the blade section 24. The active roller 235 has a built-in motor and rotates through the drive shaft of the motor. The auxiliary roller 234 is rotatably mounted on the inner wall of the first side plate 231 and near the active roller 235. A support roller 236 is mounted on the inner wall of the first side plate 231, near the drive roller 235, and is meshed with the drive roller 235. When the drive roller 235 rotates, the support roller 236 rotates synchronously with the drive roller 235. A third roller 237 is mounted on the inner wall of the first side plate 231, near the support roller 236, and is also mounted on the inner wall of the first side plate 231, near the second roller 233. A fourth roller 238 is mounted on the inner wall of the first side plate 231, near the auxiliary roller 234. A fifth roller 239 is mounted on the inner wall of the first side plate 231, near the fourth roller 238, and is also mounted on the inner wall of the first side plate 231, near the first roller 232. The auxiliary roller 234 and the fourth roller 238 are close together to clamp the unfolded face material of the second roll 22. The crossbar 230 is fixedly installed on the inner wall of the first side plate 231 near the upper end, and the crossbar 230 is also fixedly installed on the inner wall of the first side plate 231 near the second roller 233. The second roll 22 is unwound at the second roller 233. One end of the unwound second roll 22 is wrapped around the outside of the third roller 237 from below, then around the outside of the support roller 236 from above, and then around the outside of the auxiliary roller 234 from above. The auxiliary roller 234 and the fourth roller 238 clamp the second roll 22. After extending from the fourth roller 238, it is wrapped around the outside of the fifth roller 239 from above, and finally fixed on the first roller 232. The first roller 232 rewinds the unwound portion of the first roll 12.

[0037] Before quality inspection of the first roll 12, select a suitable light scraper 241 and a second roll 22 according to the size of the label on the first roll 12. Insert the light scraper 241 into the slot 244 on the fixing plate 243 through the insert block 242, and then fix the fixing plate 243 to the inner wall of the first side plate 231 through the insertion of the socket 245 and the pin 247, thus completing the installation of the selected light scraper 241. Then, the second roll 22 is placed on the second roller 233, and the second roll 22 is unwound at the second roller 233. One end of the unwound and unfolded second roll 22 is wrapped around the outside of the third roller 237 from below, then wrapped around the outside of the support roller 236 from above, and then wrapped around the outside of the auxiliary roller 234 from above. The auxiliary roller 234 and the fourth roller 238 clamp the second roll 22. After extending from the fourth roller 238, it is wrapped around the outside of the fifth roller 239 from above, and finally fixed on the first roller 232. The first roller 232 rewinds the unwound portion of the first roll 12. After the motor at the active roller 235 is started, the active roller 235 rotates, causing the active roller 235 to drive the support roller 236 to rotate, which in turn drives the second roll 22 to perform unwinding and rewinding actions.

[0038] During the quality inspection of the first roll 12, when a sticker 121 defined as a defective label appears on the first roll 12, the light scraper 241 will be positioned in the gap between the face material of the first roll 12 and the sticker 121. The front end of the light scraper 241 will scrape the sticker 121 off the face material of the first roll 12. As the first roll 12 continues to move, the sticker 121 will move along the light scraper 241 toward the drive roller 235 and gradually detach from the first roll 12. The rotation of the drive roller 235 will drive the sticker 121 toward the second roll 22. As the second roll 22 continues to move, after the front end of the sticker 121 contacts the second roll 22, the sticker 121 will adhere to the surface of the second roll 22. Then, the sticker 121 moves toward the auxiliary roller 234, which, together with the fourth roller 238, clamps the second roll 22, causing the sticker 121 and the second roll 22 to press against each other and adhere the sticker 121 to the surface of the second roll 22. As the active roller 235 rotates, the second roll 22 with the sticker 121 is wound up at the first roller 232.

[0039] 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 pushing part 26. The fixing beam 251 is fixedly installed on the inner wall of the dustproof housing 21, near the first side plate 231. The second side plates 252 are fixedly installed at both ends of the fixing beam 251, near 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 wall of the second side plate 252, near the fixing beam 251. Both ends of the first roller 232 penetrate through the first side plate 231 and extend to the outer side of the first side plate 231. The portion of the first roller 232 extending to the outer side of the first side plate 231 is inserted into the mounting through hole 253 on the second side plate 252. The first roller 232 is rotatably connected to the second side plate 252. A curved groove 254 is formed on the inner wall of the second side plate 252 near the second roller 233. Both ends of the second roller 233 penetrate the first side plate 231 and extend to its outer side. The portion of the second roller 233 extending to the outer side of the first side plate 231 is inserted into the curved groove 254 on the second side plate 252, and the second roller 233 slides within the curved groove 254. The second roller 233 performs circular motion within the curved groove 254 with the first roller 232 as the center point. The propulsion unit 26 is mounted on the fixed beam 251.

[0040] 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 central rotating rod 265. One end of the base of the electric push rod 261 is fixedly mounted on a fixed beam 251 inside 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 rods 263 are rotatably mounted at both ends of the first connecting rod 262, and are symmetrically distributed about the electric push rod 261. The central rotating rod 265 is fixedly mounted on the inner wall of the second side plate 252, near the second connecting rod 263. A insertion hole is provided on the second connecting rod 263 near the first connecting rod 262. The central rotating rod 265 is inserted into the insertion hole on the second connecting rod 263, and the second connecting rod 263 and the central rotating rod 265 are rotatably connected. 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 crossbar 230.

[0041] The fixing component 25 is used to fix the rejection component 23 and control the lowering and repositioning of the rejection component 23. When the sticker 121 appears on the first roll 12, the traveling end of the electric push rod 261 at the corresponding position extends, pushing the first connecting rod 262 forward. The displacement of the first connecting rod 262 will cause the second connecting rod 263 to swing. The second connecting rod 263 swings around the central rotating rod 265 as a fulcrum. The third connecting rod 264 located at the lower end of the second connecting rod 263 will move with the swing of the second connecting rod 263. The third connecting rod 264 will push the crossbar 230 located inside the first side plate 231 to move. When the crossbar 230 moves, the second rotating roller 233 will slide in the curved groove 254, and the second rotating roller 233 will perform circular motion around the first rotating roller 232 as a center point. At this time, the first side plate 231 will rotate around the first rotating roller 232 as a fulcrum. The light scraper 241 is then placed on the upper surface of the first roll 12 at the material table 11, allowing it to smoothly insert between the first roll 12 and the sticker 121, thus scraping the sticker 121 off the first roll 12. After the removal assembly 23 completes its operation, the traveling end of the electric push rod 261 resets, and simultaneously, the second connecting rod 263 and the third connecting rod 264 reset, causing the second roller 233 to return from the lower end of the curved chute 254 to the upper end of the curved chute 254. The light scraper 241 then disengages from contact with the surface of the first roll 12.

[0042] A label rejection method for a quality inspection slitting machine with label rejection function, based on the above, includes the following steps:

[0043] S1. Material assembly: Select a suitable shovel and insert it into the fixing plate 243. Then fix the fixing plate 243 between the two first side plates 231. Place the selected second roll 22 onto the second roller 233 and fix the unfolded end of the second roll 22 onto the first roller 232.

[0044] S2. Defective product rejection: When the sticker 121 with the defective label moves to the first side plate 231 on one side of the material table 11, the traveling 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 light scraper 241 is swung to the upper end of the first roll 12, so that the front end of the light scraper 241 is inserted between the sticker 121 and the first roll 12, lifting the sticker 121 and removing the sticker 121 from the surface of the first roll 12.

[0045] S3. Defective product collection: The rotation of the active roller 235 will drive the sticker 121 to continue moving. The front end of the sticker 121 contacts the surface of the second roll 22. The displacement of the second roll 22 drives the sticker 121 to move towards the auxiliary roller 234. The auxiliary roller 234 is used to stick the sticker 121 to the surface of the second roll 22. The sticker 121 is collected and wound up.

[0046] S4. After the selected defective sticker 121 is completely removed from the first roll 12, the electric push rod 261 is reset, which in turn resets the first side plate 231 and the light scraper 241. The active roller 235 stops rotating. At this time, the second roll 22 stops unwinding and rewinding. The rejection mechanism 2 is back in standby mode, waiting to remove the subsequent defective stickers 121 from the first roll 12.

[0047] The working principle of this application embodiment:

[0048] According to the specifications of the first roll 12, a matching squeegee 241 and a second roll 22 are selected. The squeegee 241 is fixed to the fixing plate 243 by connecting the insert block 242 and the slot 244. Then, the fixing plate 243 is fixed to the inside of the first side plate 231 by connecting the socket 245 and the pin 247. Then, the second roll 22 is installed on the inside of the first side plate 231. When a sticker 121 defined as a defective product label appears on the first roll 12, the traveling 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 slide 254 to the lower end of the curved slide 254. The shovel 241 adheres to the surface of the first roll 12, shaving the sticker 121 off the first roll 12. The second roll 22 is then unwound and rewound using the drive roller 235 and a support roller. An auxiliary roller 234 then adheres the sticker 121 located between the drive roller 235 and the auxiliary roller 234 to the surface of the second roll 22, thus collecting the sticker 121. The sticker 121 is then rewound by rewinding the second roll 22.
