Description

Technical Field

[0001] This invention relates to the technical field of automated labeling equipment, and in particular to a labeling production line with visual inspection function. Background Technology

[0002] Common beverage and medicine bottles require labels on them containing relevant product information for consumers' reference. Automated labeling equipment, due to its high speed and efficiency, is widely used in production lines in the food packaging and pharmaceutical industries.

[0003] Existing automated labeling equipment uses a labeling machine to cut label rolls into individual cylindrical labels, which are then applied to bottles and other products. These labels are then shrunk and fixed to the bottle through a heat-shrink channel. However, during the labeling process, there is a possibility of missing labels or labels failing to meet appearance standards after heat sealing. Currently, automated labeling production lines on the market lack an automated product quality inspection step. Due to the large quantity of products produced in batches, manual sampling inspection is generally used. However, manual sampling inspection is inefficient and prone to false positives and false negatives, which not only affects the overall product quality but also increases production costs. Summary of the Invention

[0004] The purpose of this application is to solve the above-mentioned problems by providing a labeling production line with visual inspection function, thereby solving the technical problem of low efficiency in product quality inspection after labeling.

[0005] To achieve the above objectives, this application provides a labeling production line with visual inspection function, including a frame, and a cover feeding mechanism, a vibratory feeder orienting mechanism, a cover conveying mechanism, a labeling mechanism, a hot-melt mechanism, a visual inspection mechanism, and a unloading mechanism disposed on the frame. The cover feeding mechanism, the vibratory feeder orienting mechanism, the labeling mechanism, the hot-melt mechanism, the visual inspection mechanism, and the unloading mechanism are arranged sequentially along the conveying direction of the cover conveying mechanism.

[0006] The cap feeding mechanism feeds the caps to the vibratory feeder orienting mechanism. The vibratory feeder orienting mechanism orients the disordered caps through vibration and transports them to the cap conveying mechanism. The cap conveying mechanism transports the caps to the labeling mechanism, which labels the caps. The cap conveying mechanism transports the labeled caps to the heat-melting mechanism, which heat-melts the caps and labels together. The cap conveying mechanism transports the heat-melted caps to the visual inspection mechanism, which inspects the heat-melting of the caps and labels. The cap conveying mechanism transports the inspected caps to the unloading mechanism, which unloads the caps. The vibratory feeder orienting mechanism includes an orienting conveying trough. The end of the orienting conveying trough is provided with an elastic locking component and a pressure plate. The elastic locking component is used to prevent the caps from falling off naturally, and the pressure plate is used to limit the vertical movement of the caps after they detach from the elastic locking component. The visual inspection mechanism includes a camera bracket and a camera device. The camera bracket is mounted on the frame, and the camera device is mounted on the camera bracket and located above the cover conveying mechanism. The camera device includes a first camera for collecting image data of the top of the cover, a second camera for collecting image data of the side of the cover, and a third camera for collecting image data of the bottom of the cover. The first camera is mounted above the cover conveying mechanism via the camera bracket; the second camera is mounted on the side of the cover conveying mechanism via the camera bracket; and the third camera is mounted at the end of the cover conveying mechanism via the camera bracket.

[0007] Compared with existing technologies, the labeling production line with visual inspection function of the present invention can quickly identify the status of the labeled products by setting a visual inspection mechanism in the labeling production line, and automatically, accurately and quickly separate defective products. It has a high degree of automation and high identification efficiency, which greatly saves labor costs, effectively improves production efficiency and production quality, and enables enterprises to reduce costs and increase efficiency.

Detailed Implementation

[0011] Please see Figure 1 This embodiment provides a labeling production line with visual inspection function. Specifically, the CCD inspection labeling production line includes a frame 1, and a cover feeding mechanism 2, a vibratory feeder orienting mechanism 3, a cover conveying mechanism 4, a labeling mechanism 5, a hot-melt mechanism 6, a visual inspection mechanism 7, and a unloading mechanism 8 disposed on the frame 1. The cover feeding mechanism 2, the vibratory feeder orienting mechanism 3, the labeling mechanism 5, the hot-melt mechanism 6, the visual inspection mechanism 7, and the unloading mechanism 8 are arranged sequentially along the conveying direction of the cover conveying mechanism 4. The cap feeding mechanism 2 feeds the caps to the vibratory feeder orienting mechanism 3. The vibratory feeder orienting mechanism 3 orients the disordered caps neatly through vibration and transports them to the cap conveying mechanism 4. The cap conveying mechanism 4 transports the caps to the labeling mechanism 5, which labels the caps. The cap conveying mechanism 4 then transports the labeled caps to the heat-melting mechanism 6, which heat-melts the caps and labels together. The cap conveying mechanism 4 then transports the heat-melted caps to the visual inspection mechanism 7, which inspects the heat-melting of the caps and labels. Finally, the cap conveying mechanism 4 transports the inspected caps to the unloading mechanism 8, which unloads the caps.

[0012] Please refer to the following: Figure 2 and Figure 3 The cover feeding mechanism 2 includes a feeding bin 21 and a feeding conveyor belt 22. The feeding bin 21 is mounted on the frame 1. The feeding conveyor belt 22 is set at a certain angle to the horizontal plane, with one end near the feeding bin 21 extending into the feeding bin 21 and the other end away from the feeding bin 21 connected to the vibrating plate orientation mechanism 3. The inclined setting of the feeding conveyor belt 22 can make full use of vertical space and effectively reduce the equipment's footprint. Specifically, there are two feeding conveyor belts 22, which can improve the feeding rate. The feeding conveyor belt conveyor device 22 includes a driving pulley 221, a driven pulley 222, a conveyor belt 223, and a belt drive motor 224. The outer peripheries of the driving pulley 221 and the driven pulley 222 are connected by the conveyor belt 223. The driving pulley 221 is connected to the belt drive motor 224. The conveyor belt 223 is also provided with several equally spaced support plates 225, which are vertically arranged on the conveyor belt 223. The belt drive motor 224 drives the driving pulley 221 to rotate, and the driving pulley 221 drives the conveyor belt 223 to move. The support plates 225 on the conveyor belt 223 extend into the feeding hopper 21, supporting part of the cover inside the feeding hopper 21, and transporting the cover to the vibratory feeder orientation mechanism 3 via the conveyor belt 223. In another embodiment, the number of feeding conveyor belt conveyors 22 can also be three or other numbers. In another embodiment, the feeding conveyor belt 22 can also be a chain conveyor or a track conveyor, as long as it can transport the cover to the vibratory feeder orienting mechanism 3.

[0013] Please refer to the following: Figure 4The vibratory feeder orientation mechanism 3 includes a vibratory feeder body 31, a vibratory feeder drive device, and an orientation conveying trough 32. The vibratory feeder body 31 is mounted on the frame 1, and the vibratory feeder drive device is connected to the vibratory feeder body 31. The vibratory feeder body 31 has an inlet 311 and an outlet 312. The inlet 311 is matched with the cover feeding mechanism 2, and the outlet 312 is matched with the orientation conveying trough 32. The orientation conveying trough 32 is located above the cover conveying mechanism 4. The cover feeding mechanism 2 conveys the cover into the vibratory feeder body 31. The vibratory feeder drive device drives the vibratory feeder body 31 to vibrate vertically. The vibrated cover changes its posture and eventually reaches the outlet 312 with the same posture and slides into the orientation conveying trough 32. The cover slides down into the orientation conveying trough 32 with the same posture under natural gravity and falls above the cover conveying mechanism 4. The directional conveying trough is adjustable in angle to the horizontal plane, allowing the cover to slide down the directional conveying trough to the cover conveying mechanism 4 at a suitable angle. The end of the directional conveying trough 32 is also provided with an elastic locking member 331 and a pressure plate 332. The elastic locking member 331 is used to prevent the cover from falling off naturally, and the pressure plate 332 is used to restrict the vertical movement of the cover after it detaches from the elastic locking member 331. In this embodiment, the elastic locking component 331 includes a spring 3311 and two rollers 3312. The spring 3311 is laterally positioned above the directional conveying groove 32. The two rollers 3312 are elastically connected by the spring 3311 and rotatably positioned on both sides of the end of the directional conveying groove 32. Under the action of the spring 3311, the two rollers 3312 move closer to each other. At this time, the width of the gap between the rollers 3312 is smaller than the outer diameter of the cover. When the cover is subjected to an appropriate external force and pushes against the gap of the rollers 3312, the gap gradually increases until the cover can be detached from the gap. Using the rollers 3312 for limiting can reduce the resistance to the cover, making it easier for the cover to detach from the gap while preventing damage to the outer surface of the cover. In another embodiment, the rollers 3312 can also be replaced by square or other shaped limiting blocks. In another embodiment, an electric or pneumatic locking component can also be provided at the end of the directional conveying groove 32 to prevent the cover from falling off naturally.

Cover fixtures 45 are provided at equal intervals on the conveyor belt 43. Under the transmission action of the drive motor 44, the driving conveyor wheel 41, the driven conveyor wheel 42, and the conveyor belt 43, the cover fixtures 45 move to below the elastic locking member 331 and engage the cover located at the elastic locking member 331, disengaging the cover from the elastic locking member 331. The pressing plate 332 then flattens the cover onto the cover fixture 45. In another embodiment, the drive method of the cover conveying mechanism 4 can also be pneumatic, hydraulic, or other drive methods.

The fixed base 561 is mounted on the mounting bracket 51 and has an opening 5611. The bottom of the central post 541 passes through the opening 5611. The rotating blades 562 are mounted on the fixed base 561 and wound around the opening 5611. The blade drive motor 563 is connected to the rotating blades 562. After the label tape falls from the central post 541 to the rotating blades 562, the rotating blades 562 rotate and cut the label tape under the drive of the blade drive motor 563. Specifically, the central post 541 has an annular notch 5411 on the same plane as the rotating blades 562 to prevent the rotating blades 562 from hitting the central post 541 when cutting the label tape. The number of rotating cutters 562 is four, and they are arranged at equal angles around the central axis of the central column 541. The output shaft of the cutter drive motor 563 is connected to the rotating shaft of one of the rotating cutters 562 via a transmission belt.

[0024] The specific detection method of the visual inspection mechanism 7 is as follows: 1) The first camera 721 photographs the top of the cover and collects the top data of the cover. If the data is normal, proceed to the next step; if the data is abnormal, the cover is determined to be a defective product; 2) The second camera 722 photographs the side of the cover and collects the side data of the cover. If the data is normal, proceed to the next step; if the data is abnormal, the cover is determined to be a defective product; 3) The unloading mechanism 8 picks up the cover that has been inspected by the first camera 721 and the second camera 722 and moves it above the third camera 723; 4) The third camera 723 photographs the bottom of the cover and collects the bottom data of the cover.

The suction cup 814 is installed at the output section of the horizontal cylinder 813. Driven by the horizontal drive track 811, the suction cup 814 moves to above the cover of the cover conveying mechanism 4. The lifting cylinder 812 drives the suction cup 814 to descend. The suction cup 814 vacuum-lifts the heat-melted cover located on the cover fixture 45. The horizontal drive track 811 moves to the beginning of the unloading conveyor belt 82. The horizontal cylinder 813 moves horizontally to above the defective product unloading port 83. At this time, the suction cup 814 releases and detaches the defective product, allowing it to fall into the defective product unloading port 83, completing the unloading of the defective product. The horizontal cylinder 813 then moves horizontally to above the unloading conveyor belt 82.
