Description

Technical Field

[0001] This utility model mainly relates to the technical field of product packaging, specifically a high-speed packaging machine based on pre-formed cartons. Background Technology

[0002] With the development of social living standards and pace of life, the variety of industrial products has increased rapidly. The role of packaging production in promoting national economic construction and improving people's material and cultural life has become increasingly prominent. As an independent industry system, the development of the packaging industry has been included in the national economic and social development plan.

[0003] Entering the 21st century, the pace of life has accelerated, and product iteration and updates have sped up, especially in the fast food industry. The technology of front-end production and clean packaging has become increasingly sophisticated, and the production speed has increased rapidly. However, the back-end transportation packaging, such as cardboard box packaging, is still in the initial stage of development. The previous manual boxing production mode can no longer meet the high-speed production conditions of the front end. Therefore, the application of automatic boxing equipment has become an inevitable development trend.

[0004] For products like instant noodles, automatic cartoning often uses hot melt adhesive. These cartons need to be custom-made to meet specific requirements, making traditional pre-formed cartons unsuitable. This leads to increased costs and low equipment versatility for businesses. Therefore, designing a carton packing machine that can use pre-formed cartons and achieve high packing efficiency has a promising market prospect. Utility Model Content

[0005] To address the shortcomings of current technology, this utility model combines existing technology and, based on practical applications, provides a high-speed carton packing machine based on pre-formed cartons. This carton packing machine realizes automatic packing of pre-formed cartons, filling a gap in the industry, and the automatic packing speed can reach a high-speed production of 20-25 cartons / minute. It can be widely used in the automatic production and packaging of instant noodles, vermicelli, and other industries.

[0006] The technical solution of this utility model is as follows:

[0007] A high-speed carton packing machine based on pre-formed cartons includes an accumulator, a conveyor pusher, and a packing machine.

[0008] The collector includes a first upper and lower clamping conveyor belt, a second upper and lower clamping conveyor belt, a push rod synchronous conveying device, a product reversing turntable, a single-row product collecting device, a single-row product lifting and pushing mechanism, and a full-case product lifting and pushing mechanism arranged in sequence. The first upper and lower clamping conveyor belt, the second upper and lower clamping conveyor belt, and the push rod synchronous conveying device are used to arrange and convey the products to the product reversing turntable. The product reversing turntable is used to flip the products from a horizontal state to a vertical state and send them into the single-row product collecting device. The single-row product lifting and pushing mechanism is used to push the single-row products row by row to the full-case product lifting and pushing mechanism. After the products reach a set number of rows, the full-case product lifting and pushing mechanism pushes the products to the conveyor push-in host.

[0009] The conveying and pushing host includes a full-case product conveying device and a full-case product packing device arranged in sequence. Below the full-case product packing device is a packing station. The full-case product packing device is used to push the product into the carton.

[0010] The packing host includes a pre-formed carton storage mechanism for storing pre-formed cartons, a carton unfolding mechanism for unfolding cartons, a packing station for loading products, a folding edge device for folding the small vertical edges on both sides of the carton, and a tape sealing device for sealing the carton.

[0011] Furthermore, the product reversing disk is a star disk structure with several toothed grooves arranged around its circumference. These toothed grooves are used to accommodate the product and flip the product from a horizontal state to a vertical state during rotation, while simultaneously pushing the product into a single-row product collection device.

[0012] Furthermore, the single-row product collection device includes baffles driven by two rows of cylinders. The baffles are arranged in pairs for limiting the products, and the baffles in the same row are arranged at intervals.

[0013] Furthermore, the collector also includes a single-row front push rod and a single-row auxiliary limiting rod. The products collected by the single-row product collecting device enter the gap between the single-row front push rod and the single-row auxiliary limiting rod, and the single-row front push rod and the single-row auxiliary limiting rod push the single-row products into the position of the single-row product lifting and pushing mechanism.

[0014] Furthermore, the single-row product lifting and pushing mechanism has a liftable push plate, and the single-row products are pushed by the push plate driven by the motor.

[0015] The product lifting and pushing mechanism has a liftable push plate, which is driven by a motor to push the product in a box.

[0016] Furthermore, the main conveyor belt of the full-case product conveying device has material compartment gaps to accommodate products, and the full-case product conveying device is used to transport full-case products to the full-case product packing device position.

[0017] Furthermore, a cardboard reciprocating conveying mechanism is provided below the pre-formed carton storage mechanism. The cardboard reciprocating conveying mechanism is used to suck up the carton at the bottom of the pre-formed carton storage mechanism and convey it to the carton unfolding mechanism position by means of a suction cup.

[0018] Furthermore, the carton unfolding mechanism is driven by a cylinder linkage structure and is equipped with a suction cup. The suction cup works in conjunction with the cylinder to unfold the carton. The unfolded carton is limited and held in place by an auxiliary pushing mechanism on the carton. The carton loading station is located behind the carton unfolding mechanism, the folding edge device is located behind the loading station, and the tape sealing carton device is located behind the folding edge device.

[0019] Furthermore, the folding edge device uses a cylinder to drive a mechanical flip plate to perform a 90° folding action, causing the small upright edges on both sides of the carton to fold.

[0020] Furthermore, the tape sealing carton device is designed with clamping belts driven by a carton sealing conveyor motor at the top and bottom, and tape applicators with folding function on both sides.

[0021] The beneficial effects of this utility model are:

[0022] 1. This utility model can realize the automatic sorting, sorting and collection of products. The collected products are uniformly pushed into pre-formed cartons. From product sorting to automatic carton picking, unfolding and sealing, the production is fully automated.

Detailed Implementation

[0036] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0037] refer to Figures 1-9 As shown, this embodiment provides a high-speed carton packing machine based on pre-formed cartons.

[0038] All components of this case packing machine are fixed on frame 35. Frame 35 and other components together form the complete case packing machine, enabling fully automated production of pre-formed cartons. Except for frame 35, all other components are mounted on the vertical and horizontal planes of frame 35. Frame 35 is a carbon steel main component and the foundational part of the entire case packing machine. It connects all components to form a relatively stable whole, coordinating the production process. Frame 35 is designed with feet for support and placement on the ground. This case packing machine mainly consists of three parts: an accumulator, a main conveyor and pusher, and the main packing unit.

[0039] As a key component of automated packing, the accumulator enables the automatic sorting, arrangement, and collection of products, and is crucial to automation.

[0040] The synchronous servo motor 1 drives the first upper and lower clamping conveyor belt 2 through the transmission system to sort and arrange the products coming from upstream to ensure uniform product spacing. The positioning servo motor 3 drives the second upper and lower clamping conveyor belt 4. With the help of sensors, the position of each product is determined. The relative position of the push rods of the second upper and lower clamping conveyor belt 4 and the push rod synchronous conveying device 5 is automatically adjusted through feedback from the servo motor encoder, so that the products accurately enter the gap between the push rods, thereby ensuring the accuracy of product position during high-speed operation.

[0041] Under the action of the push rod, the product enters the product reversing turntable 7 driven by the single-row collection servo motor 6. The product reversing turntable 7 is designed with a star disk structure. Each tooth can support a product as it flips from a horizontal to a vertical position. As the next set of teeth falls, it simultaneously pushes the previous product away into the single-row product collection device 8. The single-row product collection device 8 consists of two rows of stainless steel baffles driven by cylinders. In the top view, they are arranged in pairs to limit the movement of a product and prevent it from falling over during collection. Each time a product is collected, a set of cylinders is opened until the collection of a single row of products is completed. When the cylinders are fully open, the entire row of products enters the gap formed by the single row front push rod 11 and the single row auxiliary limit stop rod 12 driven by the single row product front push servo motor 9 and the single row surface auxiliary limit servo motor 10. At this time, the single row product front push servo motor 9 and the single row surface auxiliary limit servo motor 10 start according to the detection signal sent by the sensor, driving the single row front push rod 11 and the single row surface auxiliary limit stop rod 12 to push the entire row of products to the position of the single row product lifting and pushing mechanism 13 driven by the single row product pushing servo motor 15. The single-row product lifting and pushing mechanism 13 extends its cylinder and descends according to the system signal. The single-row product pushing servo motor 15 starts and drives the single-row product lifting and pushing mechanism 13 to push the single-row products to the whole-layer collection position (the whole-box product lifting and pushing mechanism 14 driven by the whole-box product pushing servo motor 16 waits in the position). After the required number of rows are completed, the cylinder of the whole-box product lifting and pushing mechanism 14 extends and the push plate falls. The whole-box product pushing servo motor 16 starts and drives the whole-box product lifting and pushing mechanism 14 to push the whole-box products onto the whole-box product conveying device 17.

[0042] The main conveyor belt and the main pusher section are essential devices connecting the collection machine and the carton forming main machine. After the entire carton of products is collected, under system control, the entire carton of products is pushed into the material gap of the entire carton conveying device 17 (main conveyor belt), driven by the entire carton conveying servo motor 18. Driven by the entire carton conveying servo motor 18, the products are conveyed to the carton packing device 19 (main pusher device), driven by the carton packing servo motor 20. After detecting the presence of materials, the carton packing servo motor 20 drives the carton packing device 19 to push the products into the formed carton, completing the packing of the products.

[0043] For the packing machine, this part completes the storage, retrieval, transfer, and opening of pre-formed cartons (retrieval, transfer, and opening are key steps to ensure high speed), folding the upright sides (small sides) of the cartons, folding the outer lid of the cartons, and finally applying tape to complete the automatic sealing of the cartons. The automatic packing speed of the new pre-formed cartons can reach 20-25 cartons / minute.

[0044] The cartons used by this packing machine are pre-formed cartons, which differ from the common sheet-wrapped cartons on the market that use hot melt adhesive for sealing. Pre-formed cartons have a wider range of applications; they can be packed manually or automatically on this patented packing equipment, demonstrating the broader applicability of the pre-formed carton packing machine. Its working process is as follows: The pre-formed cartons are placed in the designed pre-formed carton storage mechanism 21. The equipment starts, and the cardboard reciprocating conveyor servo motor 24 returns to its origin to the carton picking position. The cylinder on the suction mechanism extends, and the suction cup on the cylinder sucks in air to hold the bottom carton. The cylinder then lowers, and the bottom carton falls with it. The cardboard reciprocating conveyor servo motor 24 starts according to the action sequence, and the cardboard reciprocating conveyor mechanism 25 transports the cartons to the carton unfolding mechanism 26 driven by the cylinder linkage structure. At this time, the cylinder in the carton unfolding mechanism 26 retracts, the opening suction cup holds the top of the carton, and the opening cylinder extends again to cooperate with the opening suction cup to unfold the pre-formed carton, completing the carton opening. At this time, the cylinder in the auxiliary pushing mechanism 23 on the carton extends and drives the flip plate to limit and maintain the unfolded shape of the formed carton. The auxiliary pushing servo motor 22 and the carton forming conveying servo motor 31 on the carton start simultaneously. Under the action of the flip plate of the auxiliary pushing mechanism 23 on the carton driven by the auxiliary pushing servo motor 22 and the push rod driven by the carton forming conveying servo motor 31, the carton moves to the packing station. After stopping, the entire layer of products is pushed into the carton by the carton packing device 19. After packing is completed, the carton with the products packed enters the next station under the action of the push rod driven by the carton forming conveying servo motor 31 for folding the small vertical sides of the carton. The folding of the small upright edge is achieved by a cylinder driving a mechanical flip plate to achieve a 90° folding action. After the upright edge is folded, the carton sealing pre-positioning servo motor 30 drives the carton sealing pre-positioning push device 29 and the push rod driven by the carton forming conveyor servo motor 31 to push the carton into the tape sealing carton device 32. The tape sealing carton device 32 is designed with clamping belts driven by the carton sealing conveyor motor 34 at the top and bottom, and tape applicators 33 with folding function on both sides. As the carton enters, the folding of the top and bottom covers is completed and the tape application begins at the same time, thus completing the automatic packing of the pre-formed carton.

[0045] The carton packing machine in this embodiment fills a gap in the industry by enabling automatic packing of pre-formed cartons. The automatic packing speed can reach a high-speed production of 20-25 cartons / minute, and it can be widely used in the automatic packing of instant noodles, vermicelli and other industries.
