Description

Technical Field

[0001] This utility model belongs to the field of food packaging technology, specifically an automatic packaging device for multi-pack products. Background Technology

[0002] As living standards improve, people's demands for material culture are also increasing, including higher standards for food. To develop different types and specifications of products, food manufacturers often design their products in single, double, and multi-packs to meet the needs of diverse consumers. This allows companies to more precisely adapt to different scenarios; for example, single packs target the immediate consumption needs of fast-paced urban dwellers, double packs are precisely suited for small families, and multi-pack gift boxes target the social gift and bulk purchasing markets. This differentiated packaging strategy not only achieves full-cycle coverage from initial taste to bulk purchase but also strengthens the price range of the product line through specification differences. This allows brands to simultaneously satisfy diverse consumer demands such as convenience, cost-effectiveness, and a sense of occasion, ultimately forming a closed-loop business model of "small packaging attracting customers, multi-packs generating profits."

[0003] Food packaging machines primarily transport manually placed products to the packaging area via a conveyor belt. The packaging machine then folds the roll film into a bag shape, places the product inside the bag, and heat-seals it to form a packaging cavity. As the conveyor belt rotates, the packaged products are transported to the exit for centralized boxing.

[0004] However, since it is impossible for manual labor to stack multiple products neatly on a food packaging machine at the same time, in actual production, multi-pack products are mostly bagged manually. This manual bagging method is not only inefficient, but also has a long turnaround time and is prone to cross-contamination, causing food safety problems. Utility Model Content

[0005] To address the problems of low efficiency, long turnaround time, and potential cross-contamination and food safety issues associated with manual packaging of multiple products, this invention provides an automatic packaging device for multiple products.

[0006] This utility model is achieved through the following technical solution:

[0007] An automatic packaging device for multi-pack products includes a fully automatic stretch film packaging machine, and the entrance of the fully automatic stretch film packaging machine is provided with a stacking mechanism that can neatly place several products.

[0008] The stacking mechanism includes a conveying and guiding mechanism. At the end of the conveying and guiding mechanism, a stacking mechanism is connected and installed to arrange the products neatly. A conveying mechanism is provided between the conveying and guiding mechanism and the fully automatic stretch film packaging machine. A handling mechanism is provided between the conveying mechanism and the fully automatic stretch film packaging machine to move the products on the conveying mechanism to the entrance of the fully automatic stretch film packaging machine.

[0009] The conveyor guiding mechanism includes a support frame, on which a conveyor belt is connected and installed. A fixed frame is connected and installed at the upper end of the support frame, and two guide rods in a "figure-eight" shape are connected and installed on the fixed frame to allow products to pass through the narrow opening in sequence.

[0010] The placement mechanism includes a support plate, on which two rollers are rotatably connected and installed near the conveyor guide mechanism. The two rollers are connected by a synchronous belt with evenly arranged paddles on the synchronous belt. On the side of the support plate away from the conveyor guide mechanism, a motor that drives the rollers to rotate is connected and installed.

[0011] A further improvement of this utility model is that the handling mechanism includes a triangular robotic arm, and a suction cup is connected and installed at the free end of the triangular robotic arm.

[0012] A further improvement of this utility model is that a visual recognition probe is connected and installed on the triangular robotic arm.

[0013] A further improvement of this utility model is that a first sleeve is slidably connected and installed on the fixed frame, a connecting rod is connected and installed below the first sleeve, a second sleeve is rotatably connected and installed below the connecting rod, the second sleeve is slidably connected to the guide rod, and a first bolt is provided on both the first sleeve and the second sleeve.

[0014] A further improvement of this utility model is that the support plate is provided with a rotating shaft on the side near the conveying and guiding mechanism, the rotating shaft is provided with a guide groove, the rotating roller is connected to the rotating shaft with a sliding sleeve, and the rotating roller is provided with a second bolt that abuts against the bottom of the guide groove.

[0015] A further improvement of this utility model is that the number of conveyor guiding mechanisms is set to two arranged at the beginning and end, and the conveyor belt speed on the tail conveyor guiding mechanism is higher than the conveyor belt speed on the head conveyor guiding mechanism.

[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0017] In operation, the operator lays the product flat on the conveyor belt of the conveyor guide mechanism. As the conveyor belt rotates, the product is conveyed to the other end. Under the constraint of the guide rod, the product accumulates at the narrow opening formed by the guide rod, allowing the product to be output one by one in an orderly manner from the narrow opening. Then, the product is conveyed to the next conveyor guide mechanism with a faster operating speed, ensuring that there is a certain distance between the products. The guide rod guides the product to the placement mechanism. The motor of the placement mechanism drives the synchronous belt to rotate through the rotating roller, causing the pick to push the product onto the conveyor mechanism at the same speed. The conveyor mechanism rotates, allowing the products to fall neatly onto the conveyor mechanism in sequence. According to the predetermined number of products, the products are conveyed to the entrance side of the fully automatic stretch film packaging machine. The conveyor mechanism, conveyor guide mechanism, and placement mechanism stop operating, waiting for the handling mechanism to move multiple products to the fully automatic stretch film packaging machine. The conveyor mechanism continues to operate. After each group of products is stretched to a certain distance, the conveyor guide mechanism and placement mechanism restart, placing the products onto the conveyor mechanism. This device arranges products in a queue and transports multiple products in each group onto a fully automatic stretch film packaging machine in an orderly manner, thereby achieving mechanized production of multi-product packaging. This greatly improves production efficiency, shortens the packaging cycle, avoids cross-contamination, and ensures food safety. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] like Figure 1-4 As shown, an automatic packaging device for multi-pack products includes a fully automatic stretch film packaging machine 1, and a stacking mechanism 2 at the entrance of the fully automatic stretch film packaging machine 1, which can neatly place several products.

[0026] The stacking mechanism 2 includes a conveying guide mechanism 3 connected end to end. The conveying guide mechanism 3 can arrange the disordered products into a row. The end of the conveying guide mechanism 3 is connected to a stacking mechanism 4 that can arrange the products neatly. Between the conveying guide mechanism 3 and the fully automatic stretch film packaging machine 1, there is a conveying mechanism 5 that can transfer the products in groups of multiple to the conveying mechanism 5. The conveying mechanism 5 is a plate chain conveyor belt mechanism controlled by a servo motor, which can provide better support for the products. Alternatively, a conveyor belt structure can be used. Between the conveying mechanism 5 and the fully automatic stretch film packaging machine 1, there is a handling mechanism 6 that can move the products on the conveying mechanism 5 to the entrance of the fully automatic stretch film packaging machine 1.

[0027] The conveying guide mechanism 3 includes a support frame 31, on which a motor-driven conveyor belt 32 is connected and installed. A fixed frame 33 is connected and installed at the upper end of the support frame 31. Two guide rods 34 arranged in a "V" shape are connected and installed on the fixed frame 33, which allow products to pass through the narrow opening in sequence.

[0028] The placement mechanism 4 includes a support plate 41 connected and installed on one side of the second conveyor guide mechanism 3. Two rollers 42 are rotatably connected and installed on the side of the support plate 41 near the conveyor guide mechanism 3. The two rollers 42 are connected by a synchronous belt 43. The synchronous belt 43 will not slip, so that multiple products can maintain the same packaging state. The synchronous belt 43 is provided with evenly arranged paddles 44. The spacing between the paddles 44 should be greater than the size of the product. A motor 45 that drives the rollers 42 to rotate is connected and installed on the side of the support plate 41 away from the conveyor guide mechanism 3. The linear speed of the motor 45 driving the synchronous belt 43 to rotate should match the speed of the conveyor belt 32.

[0029] In use, the operator lays the product flat on the conveyor belt 32 of the conveyor guide mechanism 3. As the conveyor belt 32 rotates, the product is conveyed to the other end. Under the constraint of the guide rod 34, the product accumulates at the narrow opening formed by the guide rod, so that the product is output one by one in an orderly manner from the narrow opening. Then the product is conveyed to the next conveyor guide mechanism 3 with a faster operating speed, so that there is a certain distance between the products. The guide rod 34 guides the product to the placement mechanism 4. The motor 45 of the placement mechanism 4 drives the synchronous belt 43 to rotate through the rotating roller 42, so that the picks 44 on the synchronous belt 43 push the product to the conveyor mechanism 5 at the same speed. The conveyor mechanism 5 rotates, so that the product falls neatly on the conveyor mechanism 5 in sequence and is grouped according to a predetermined number of pieces. The product is conveyed to the entrance side of the fully automatic stretch film packaging machine 1 and stops. Then the handling mechanism 6 carries multiple products to the packaging entrance of the fully automatic stretch film packaging machine 1 according to a specific rhythm. The fully automatic stretch film packaging machine 1 completes the packaging of multiple products. This device arranges products in a queue and transports multiple products in each group to a fully automatic stretch film packaging machine 1 in an orderly manner, realizing mechanized production of multi-product packaging. This avoids manual packaging of multiple products, greatly improves production efficiency, shortens the packaging cycle, avoids cross-contamination, and ensures food safety.

[0030] The conveying mechanism 6 includes a triangular robotic arm 61, with a suction cup 62 connected to its free end. The suction cup 62 is connected to the centrifuge via a pipe, using negative pressure to hold the product in place. Using the suction cup 62 to grasp the product reduces damage, prevents deformation, and improves product consistency and quality. The triangular robotic arm 61 saves space, is environmentally friendly, and is suitable for food processing applications.

[0031] It should be noted that the handling mechanism can also use a bionic human hand robotic arm to grip and handle multiple products in each group through a clamp. Alternatively, a flipping mechanism can be used to lift multiple products in each group to a certain angle, allowing them to slide naturally into the packaging entrance of the fully automatic stretch film packaging machine 1, thus completing the handling and transfer action.

[0032] The triangular robotic arm 61 is equipped with a vision recognition probe 63. The vision recognition probe 63 identifies the position of the product in real time and transmits the signal to the controller. The controller controls the triangular robotic arm 61 to synchronize its speed with the conveying mechanism 5. The product is then picked up by the suction cup 62 and transported to the fully automatic stretch film packaging machine 1. This enables the conveying guide mechanism 3, the placement mechanism 4, and the conveying mechanism 5 to carry out continuous conveying, which greatly improves the packaging efficiency.

[0033] It should be noted that after multiple products from each group land on the conveyor mechanism 5, the conveyor mechanism 5 needs to accelerate its rotation to maintain a certain distance between the next group of products and the previous group. This prevents the suction cups 62 on the handling mechanism 6 from picking up the wrong products or touching the next group of products, which would affect the product specifications and packaging. When a product does not meet the preset requirements, the visual recognition probe 63 will stop operating and issue an alarm, prompting personnel to handle the situation, preventing unqualified products from being packaged, and improving the product yield.

[0034] The fixed frame 33 has a first sleeve 35 slidably connected to it, a connecting rod 36 connected below the first sleeve 35, and a second sleeve 37 rotatably connected below the connecting rod 36. The second sleeve 37 is slidably connected to the guide rod 34, and both the first sleeve 35 and the second sleeve 37 are provided with first bolts 38. This allows the included angle of the two guide rods 34 to be adjusted to accommodate products of different specifications, enabling products of different specifications to be queued and conveyed downwards in sequence.

[0035] The support plate 41 has a rotating shaft 46 near the conveying guide mechanism 3. The rotating shaft 46 has a guide groove 47. The rotating roller 42 is connected to the rotating shaft 46 by a sliding sleeve. The rotating roller 42 has a second bolt 39 that abuts against the bottom of the guide groove 47. By sliding the rotating roller 42 on the rotating shaft 46 and then tightening it with the second bolt 39, the position of the paddle 44 can be adjusted so that the paddle 44 can move the product to the exact center, so that the product can be accurately placed on the conveying mechanism 5, ensuring the consistency of product placement and improving the standardization of product packaging.

[0036] The conveyor guide mechanism 3 is configured with two units arranged at the beginning and end, with the conveyor belt 32 on the tail conveyor guide mechanism 3 traveling at a higher speed than the conveyor belt 32 on the head conveyor guide mechanism 3. When products are transferred from the slower head conveyor belt 32 to the faster tail conveyor belt 32, the speed difference causes a certain distance to be created between the products that were originally close together, making it easier for the placement mechanism 4 to smoothly transfer the products from the conveyor belt 32 to the conveyor mechanism 5.

[0037] The controller 12 can be a common PLC controller, such as the Siemens S7-1500 series. By setting the program, the conveying guide mechanism 3, the placement mechanism 4 and the conveying mechanism 5 are linked together, so that the products are conveyed to the fully automatic stretch film packaging machine 1 according to the predetermined requirements. Since the triangular robotic arm 61 has its own control chip, it can use its own vision to move the multiple products on the conveying mechanism 5 to the conveyor belt on the fully automatic stretch film packaging machine 1 at the same time for subsequent packaging.

[0038] In use, the processed products are laid flat on the conveyor guide mechanism 3. As the conveyor belt 32 rotates, the products accumulate at the narrow opening of the guide rod 34, and then the products flow out one by one. When the products are conveyed to the next conveyor guide mechanism 3, due to the high speed of the conveyor belt 32 of the second conveyor guide mechanism 3, a certain distance is created between the products. The guide rod 34 continues to guide the products to the placement mechanism 4. The rotating paddle 44 on the placement mechanism 4 pushes the products onto the conveyor mechanism 5 in sequence according to the set requirements, so that multiple products are formed into a group. Then, the triangular robotic arm 61 picks them up through the suction cup 62 and places them on the fully automatic stretch film packaging machine 1 for packaging multiple products. This device realizes the mechanized production of multiple product packaging by arranging the products in a queue and transporting each group of multiple products to the fully automatic stretch film packaging machine 1 in an orderly manner according to the requirements. This ensures that each group of multiple products maintains the same specifications, improves product consistency, increases production efficiency, shortens the packaging cycle, avoids cross-contamination during manual bagging of multiple products, and ensures food safety.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
