Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic packaging equipment, and particularly relates to a labeling and packaging system with visual detection and a packaging method thereof. BACKGROUND

[0002] As a mature technology, in-mold labeling has been widely used in the production of plastic products such as food packaging and daily-use containers. This technology involves placing printed labels directly into the injection molding machine, where they are fused with the product body through injection molding. The resulting labels are visually appealing, durable, and resistant to counterfeiting, and they are environmentally friendly and do not leave a label feel. Currently, high-end production lines on the market generally pursue automation and intelligence. Among them, the integrated visual inspection system has become a key link to ensure product quality. However, existing in-mold labeling solutions with visual inspection have the following main modes and defects: 1. Loose system architecture and low integration: The most common solution is to use an "in-mold labeling system" and a "visual inspection system" in separate modes. That is, the in-mold labeling machine first completes a series of actions such as label taking, label placing, and product taking, and then transfers the taken product to a separate, specially designed visual inspection device for repositioning and detection through a conveyor belt or manual method. This architecture is essentially a simple series connection of two or even three sets (if including an independent sorting device) of equipment. The direct disadvantages are: a large equipment footprint, increasing the cost of the plant; a complex overall system with a lot of redundant structures (such as separate racks, control systems, and transmission mechanisms); high manufacturing and maintenance costs. 2. Bottlenecks in production efficiency and cycle: Since the product needs to be repositioned, clamped, and photographed during the transfer process, the entire production cycle is limited by the slowest link, making it difficult to achieve high-speed continuous production. Multiple positioning and handling not only increase the complexity of the mechanism but also significantly increase the risk of scratching, contamination, or dropping the product during the transfer process, especially for products with extremely high appearance quality requirements (such as transparent cups and high-end cosmetic containers). 3. Detection difficulties for multi-cavity injection molding machines: To improve efficiency, multi-cavity injection molding machines are commonly used in injection molding production. In existing technologies, the products taken by the labeling machine are usually arranged in multiple rows and columns as in the injection molding machine. Traditional visual inspection stations are usually designed for single-row or single-camera, which cannot effectively photograph multiple rows of products at the same time. Therefore, either a highly complex multi-camera synchronous shooting system needs to be designed, which is extremely costly, or additional "material arranging" or "distance changing" mechanisms need to be added to rearrange the products into a single row before detection, which further increases the complexity and failure rate of the equipment and reduces the detection efficiency. 4. Coordination and stability issues: Two independent systems mean that two control systems (PLC, industrial computer, etc.) are needed for data interaction and coordination. This interaction often has the risk of communication delay and signal desynchronization, affecting the stability and reliability of production. Any fault in a subsystem can cause the entire production line to stop, making it more difficult to troubleshoot. 5. Outdated backend processing methods: In terms of defective product handling, many existing devices still use random and disordered collection methods (such as directly blowing into a waste bin), or rely entirely on manual sorting and packaging.The former cannot realize the traceability analysis of defective products, and the latter not only has high labor cost and low efficiency, but also has the hidden danger of secondary pollution of products, and is difficult to meet the requirements of modern intelligent factory on data and automation.

By deeply integrating the visual detection system 500 into the in-mold labeling system, the whole process automation of label taking, labeling, product taking, distance changing, detection and sorting is realized, the equipment floor area and the overall cost are greatly reduced, and the system stability and production efficiency are improved; by configuring the product taking assembly 340 to change the distance automatically, seamless conversion from taking multiple rows of products from the injection molding machine to single row detection is realized, the problems of low efficiency, large floor area, poor cooperativeness and the need for multiple positioning of products in the traditional scheme due to independent system are solved, and the production efficiency and system stability are fundamentally improved.

[0034] Referring to Figure 2 , Figure 4 and Figure 5 , Figure 4 is a partial structural schematic diagram of a labeling packaging system with visual detection in an embodiment of the present application, Figure 5 is a structural top view of the middle hand device 300 of a labeling packaging system with visual detection in an embodiment of the present application cooperating with an injection molding machine.

[0035] Further, in the embodiment, the conveying assembly 320 comprises a first sliding rail 321 arranged on the mounting beam 310 in a first direction, a middle hand sliding member 322 in sliding connection with the first sliding rail 321, a second sliding rail 323 arranged on the middle hand sliding member 322 and extending in a direction different from the first direction, a mounting bracket 324 in sliding connection with the second sliding rail 323, the label taking assembly 330 being arranged on one side of the mounting bracket 324 close to the label library 200, the product taking assembly 340 being arranged on one side of the mounting bracket 324 close to the adapter 400, and a conveying driving unit 325 for driving the middle hand sliding member 322 and the mounting bracket 324 to slide.

[0036] Specifically, the middle hand sliding member 322 comprises a first sliding plate, a connecting plate and a mounting plate, the first sliding plate being in sliding connection with the first conveying rail, one end of the connecting plate being connected with the first sliding plate, a second end of the connecting plate being connected with the mounting plate, the second sliding rail 323 being arranged on the mounting plate, and the direction of the second sliding rail 323 being perpendicular to the first direction in a horizontal plane.

[0037] Specifically, the conveying unit is a driving motor arranged on the mounting beam 310 and the mounting plate respectively, and the two driving motors are connected with the first sliding plate and the mounting bracket 324 through a transmission belt respectively.

[0038] Referring to Figure 4 , Figure 6 and Figure 7 , Figure 6 is a taking state diagram of the product taking assembly 340 of the label packaging system with visual detection in the embodiment of the application; Figure 7 is a detection state diagram of the product taking assembly 340 of the label packaging system with visual detection in the embodiment of the application.

[0039] Further, in the embodiment, the taking component 340 comprises a first mounting plate 341 fixed to the mounting frame 324, at least one third slide rail 348 being obliquely arranged on the first mounting plate 341; the first taking part 342 is in sliding connection with the third slide rail 348, a plurality of first vacuum suction cups 343 being horizontally arranged on the first taking part 342; gaps are left between the first vacuum suction cups 343; the second taking part 345 is in sliding connection with the third slide rail 348, a plurality of second vacuum suction cups 346 being horizontally arranged on the second taking part 345; gaps are left between the second vacuum suction cups 346; a first driving cylinder 344 is used to drive the first taking part 342 to move along the third slide rail 348; a second driving cylinder 347 is used to drive the second taking part 345 to move along the third slide rail 348; wherein the first driving cylinder 344 and the second driving cylinder 347 are configured to drive the first taking part 342 and the second taking part 345 to move towards or away from each other, so as to realize the mode conversion between the multi-row products and the single-row products. Through the unique oblique slide rail and driving cylinder design of the taking component 340, the multi-row products taken out by the multi-cavity injection molding machine mold 830 can be directly changed into single-row products during the returning process, so that all the products can pass through the vision work station in a consistent posture and position, ensuring the accuracy and reliability of detection and solving the problem of multi-cavity product detection. At the same time, through the oblique slide rail and the independent driving taking part design, mechanical synchronous control of product row conversion is realized, avoiding collision or falling of products during distance conversion.

[0040] Specifically, the power output end of the upper end of the first driving cylinder 344 is connected with the first taking part 342, and the power output end of the lower end of the second driving cylinder 347 is connected with the second taking part 345; during taking, the first taking part 342 is fixed to the upper end of the first mounting plate 341 under the action of the first driving cylinder 344, and the second taking part 345 is fixed to the lower end of the first mounting plate 341 under the action of the second driving cylinder 347; after taking, the first driving cylinder 344 drives the first taking part 342 to move downward, and the second driving cylinder 347 drives the second taking part 345 to move upward, so as to combine the two rows of taking grooves into one row.

[0041] Specifically, the first taking part 342 comprises a first taking body and a plurality of first installation positions extending to the second taking part 345, each of the first installation positions is arranged at intervals, and the first vacuum chuck 343 is fixed to the first installation position. The second taking part 345 comprises a second taking body and a plurality of second installation positions extending to the first taking part 342, each of the second installation positions is arranged at intervals, and the second vacuum chuck 346 is fixed to the second installation position. The first installation positions and the second installation positions are staggered in the first direction; when the first taking part 342 and the second taking part 345 move towards each other to the merging state, each of the first vacuum chuck 343 and the second vacuum chuck 346 is alternately arranged to form a compact single row. Since the first installation positions and the second installation positions are staggered, when the two taking parts are merged, they are like two sets of comb teeth staggered and engaged, so that the products can be closely arranged together, thereby saving space to the maximum and providing great convenience for the subsequent detection or packaging station.

[0042] Preferably, the third sliding rail 348 is provided with two sliding rails, which guarantees the stability of the transmission.

The plurality of third vacuum chucks 332 are arranged side by side, so that the taking label assembly 330 can take a plurality of labels at a time, which matches the production rhythm of the multi-cavity injection molding machine mold and significantly improves the production efficiency.

[0044] Referring to Figure 8 , Figure 8 is Figure 3 the structure enlargement view of A in FIG. 4.

[0045] Further, in the embodiment, the switching device 400 comprises a switching manipulator 410 for taking the product from the taking assembly 340 and turning the product, and a placing manipulator 420 for receiving the product from the switching manipulator 410 and placing the product on the conveying device 600. Specifically, the switching manipulator 410 turns the product by 180 degrees and then delivers the product to the placing manipulator 420, the placing manipulator 420 turns the product by 90 degrees and then places the product on the conveying assembly 320; through the cooperative operation of the switching manipulator 410 and the placing manipulator 420, the product is flexibly transferred from the taking to the conveying, thereby avoiding the problem of out-of-control posture of the product caused by the direct placing of the traditional manipulator.

[0046] Referring to Figure 9 , Figure 9Figure 7 is a structural schematic diagram of an adapter robot 410 of a labeling and packaging system with visual inspection in an embodiment of the present application;

[0047] Further, in the embodiment, the adapter robot 410 comprises a first mounting rod 421, a first mounting beam 422, a first turnover frame 423, and a first driving motor 424. The first mounting rod 421 is provided with a vertical fourth sliding rail. The first mounting beam 422 is slidably connected to the first mounting rod 421 through the fourth sliding rail. The first turnover frame 423 is rotatably arranged on the first mounting beam 422 and is provided with a fourth vacuum chuck for adsorbing a product. The first driving motor 424 is used to drive the first turnover frame 423 to turn over. The lifting and turning functions of the adapter robot 410 naturally expose the bottom of the product during the transfer process, thereby providing an optimal viewing angle for visual inspection and preparing an ideal posture for subsequent placement.

[0048] Specifically, the placement robot 420 comprises a second mounting rod, a second mounting beam, a second turnover frame, and a second driving motor. The second mounting rod is provided with a vertical fifth sliding rail. The second mounting beam is slidably connected to the second mounting rod through the fifth sliding rail. The second turnover frame is rotatably arranged on the second mounting beam and is provided with a fifth vacuum chuck for adsorbing a product.

The precise turning control of the placement robot 420 ensures that the product can be placed on the conveying belt in a stable posture, thereby avoiding product dumping or misplacement and providing a reliable foundation for subsequent sorting.

[0049] Referring to Figure 2 , Figure 4 and Figure 9 Further, in the embodiment, the visual inspection system 500 comprises a first detection member 510, a second detection member 520, and a third detection member 530. The first detection member 510 is fixed to the first mounting beam 422 of the adapter robot 410 and is located at the side of the taking assembly 340. The first detection member 510 is provided with two detection cameras, one of which is used to detect the mouth of the product when the taking assembly 340 moves, and the other of which is used to detect the inner wall of the product when the taking assembly 340 moves. The second detection member 520 is arranged below the taking assembly 340 and is used to detect the side of the product. The third detection member 530 is arranged above the conveying device and is used to detect the bottom of the product. By arranging multi-angle visual stations on the taking path and the adapter path, full-coverage detection of the mouth, the inner wall, the side, and the bottom of the product is achieved, thereby solving the problem of blind spots existing in traditional single-station detection.

[0050] Specifically, the second detection member 520 and the third detection member 530 are provided with at least one detection camera.

[0051] Specifically, the first detection member 510 and the second detection member 520 can be industrial detection cameras.

Through real-time linkage of the sorting assembly 640 and the visual system, automatic separation and directional conveying of good products and defective products are realized, the traditional manual sorting mode is completely replaced, and the sorting accuracy and efficiency are improved. The defective products are stacked by the stacking machine 810, so that the neatness of the site and the traceability of the defective products can be realized.

[0053] The application provides a packaging method based on the label packaging system with visual detection, comprising the following steps:

[0054] S1: the conveying assembly 320 drives the label taking assembly 330 to extend into the label library machine 200 to take out label paper;

[0055] Specifically, the conveying driving unit 325 is started to drive the middle hand sliding piece 322 to move along the first sliding rail 321 on the mounting beam 310, so as to drive the whole mounting frame 324, the label taking assembly 330 and the product taking assembly 340 on the mounting frame 324 to move towards the label library machine 200. Then, the other conveying driving unit 325 drives the mounting frame 324 to move along the second sliding rail 323 on the mounting plate, so that the label taking assembly 330 accurately extends into the label library machine 200. The plurality of third vacuum suction cups 332 on the label taking assembly 330 are connected with vacuum under the control of the control box 700, so as to simultaneously adsorb and take a plurality of label papers.

[0056] S2: the conveying assembly 320 drives the label taking assembly 330 and the product taking assembly 340 to enter the injection molding machine mold 830, the label taking assembly 330 conveys label paper to the injection molding machine mold 830, installs the label paper in the injection molding machine mold 830, and the product taking assembly 340 takes out the processed product from the injection molding machine mold 830;

[0057] Specifically, after the label is taken, the conveying driving unit 325 drives the middle hand device 300 to move as a whole, so that the installation beam 310 carries the label taking assembly 330 and the product taking assembly 340 into the space of the injection molding machine mold 830. At this station, the label taking assembly 330 performs a label placing action to accurately place the adsorbed label paper into the injection molding machine mold 830. At the same time, the product taking assembly 340 performs a product taking action, and the first product taking part 342 and the second product taking part 345 are located at the upper end and the lower end of the first installation plate 341 under the action of the first driving cylinder 344 and the second driving cylinder 347, so that the first vacuum suction cup 343 and the second vacuum suction cup 346 thereon form two rows of layout matched with the multi-cavity injection molding machine mold, and are connected to the vacuum to take out the product in the injection molding machine mold 830. This synchronous action greatly shortens the production rhythm.

[0058] S3: The conveying assembly 320 drives the product taking assembly 340 to retreat, and in the retreat process, the product taking assembly 340 combines the multiple rows of products into a single row, so that the single row of products passes through the visual inspection system, and the visual system performs a first detection on the side surface and the label joint of the product; the visual system performs a second detection on the mouth and the inner wall of the product;

[0059] Specifically, the middle hand device 300 is withdrawn from the injection molding machine. In the retreat process, the first driving cylinder 344 drives the first product taking part 342 to move downward along the third slide rail 348 arranged obliquely, and at the same time, the second driving cylinder 347 drives the second product taking part 345 to move upward along the third slide rail 348. The two product taking parts move towards each other, thereby combining the originally two rows of products into a compact single row. When the product passes through the second detection part 520 arranged directly below the path, the industrial camera takes a photo of the side profile and the label of the product, detects the shape, label wrinkles, bubbles, etc., and completes a first detection. When the product passes through the first detection part 510 arranged on the side of the path, the two detection cameras on the first detection part 510 take photos of the mouth and the inner wall of the product under the control of the trigger signal, detect the roundness, gaps, etc., and complete a second detection.

[0060] S4: The product is transferred from the product taking assembly 340 to the conveying device 600 through the adapter 400, and a third detection is performed on the bottom of the product through the visual inspection system, and the detection result is sent to the conveying device;

[0061] Specifically, when the middle hand device 300 retreats to the initial position, the switching device 400 starts to work. First, the switching robot 410 is started to make the fourth vacuum chuck on the first turnover frame 423 contact and adsorb the product on the taking assembly 340. Then, the first turnover frame 423 is driven to turn over 180 degrees by the first driving motor 424, so that the bottom of the product faces outward. After that, the putting robot 420 moves to the receiving position, and the second turnover frame thereof is turned over to the appropriate angle by the second driving motor to receive the product from the switching robot 410. The putting robot 420 drives the second turnover frame to turn over 90 degrees to adjust the product to the posture with the bottom facing upward, and then stably places the product on the first conveying assembly 610 of the conveying device 600, and the bottom of the product is detected three times by the third detection 530.

[0062] S5: According to the results of the visual detection system 500, the products are divided into good products and bad products by the sorting assembly 640 on the conveying device 600, and the good products are conveyed to the bagging packaging machine 820 for bagging and packaging, and the bad products are conveyed to the stacking machine 810 for stacking.

[0063] Specifically, after the products enter the first conveying assembly 610, they are conveyed forward. The image processing system in the control box 700 has processed and analyzed the images transmitted by the visual detection system 500, and made a good / bad product judgment and record for each product. When the products move to the sorting assembly 640 with the conveying belt, the control box 700 controls the sorting assembly 640 to act according to the product serial number and the record results. Among them, the good products are conveyed to the second conveying assembly 620 and enter the bagging packaging machine 820 for automatic packaging; the bad products are conveyed to the third conveying assembly 630 and finally conveyed to the stacking machine 810 for unified collection and arrangement.

[0064] Through the above steps, the full-process integration and automation of taking labels, in-mold operation, product taking, online distance changing, multi-angle visual detection, automatic transfer, and finally intelligent sorting and packaging are realized, and the production efficiency and product quality are significantly improved.

[0065] As can be seen from the above, the label packaging system with visual detection in the application realizes the full-process automation of taking labels, labeling, taking products, changing distances, detecting, and sorting by deeply integrating the visual detection system into the in-mold labeling system, greatly reduces the equipment floor area and overall cost, and improves the system stability and production efficiency; by configuring the taking assembly to automatically change distances, seamless conversion from taking multiple rows of products from the injection molding machine to single-row detection is realized, and problems such as low efficiency, large floor area, poor coordination, and the need for multiple positioning of products in the traditional scheme are solved, which fundamentally improves the production efficiency and system stability.

[0066] From the above, the packaging method based on the labeling and packaging system with visual detection in the application integrates a series of steps such as label taking, piece taking, online distance changing, multi-station visual detection, automatic transfer and intelligent sorting into a continuous and smooth automatic circulation, which significantly reduces manual intervention and improves production efficiency and product yield.

[0067] The above is the preferred embodiment of the application, and it should be pointed out that those skilled in the art can make several improvements and refinements without departing from the principles of the application, and these improvements and refinements are also considered within the protection scope of the application.
