Description

Technical Field

[0001] This invention belongs to the field of, specifically, a container and lid alternating left-right stacking conveying and sealing machine. Background Technology

[0002] The production of everyday disposable plastic tableware, such as disposable cups, bowls, boxes, and lids, as well as ice cream packaging and supermarket fruit and vegetable packaging, is mainly carried out by sheet thermoforming in the existing technology. However, due to the different usage and purposes of cups, bowls, boxes, and lids, their shapes vary. With social progress, the shortage of human resources, and the increase in labor costs, making equipment fully automated and intelligent to improve production efficiency and reduce labor costs is an urgent issue for various industries. Although the existing three-station thermoforming machine has three actions per mold and is the fastest output equipment at home and abroad, the first station is thermoforming and then transferring to the second station for punching and shearing, which may cause deformation and uneven edges. Also, after punching and shearing, the material needs to be carried to the third station for unloading and stacking. Therefore, three points are reserved and it is not possible to completely cut off the material. After the material is unloaded, burrs and uneven edges will inevitably remain at three points. Due to the stacking, the conveyor components are also technically damaged. As a result, lids and products that cannot be placed stably on their own, including products with a height greater than the diameter and products produced by misaligned molds, cannot be automatically packed and sealed. To address the aforementioned technical shortcomings while maintaining the original speed and efficiency, I invented a three-action thermoforming punching, shearing, conveying, and packing production line per mold in December 2022. However, this production line is only suitable for thermoforming punching and shearing of general containers and boxes. While it is two-fifths faster than traditional single-mold forming punching and shearing technology, and solves the technical defects of the aforementioned three-station thermoforming equipment in terms of quality control, unloading, and inability to convey layers for bagging and packing, this invention has limitations in the stacking of thin sheet caps and the single-row stacking conveying robot's single-row transfer and conveying speed. Clearly, this production line is only suitable for products with a stacking height sufficient to meet the corresponding single-row stacking conveying and packing requirements. The stacking height cannot meet the requirements. If the receiving speed of the receiving station is faster than the unloading speed of the conveying station, it obviously cannot keep up with the three actions per mold and the cap making is too light and the connection height is insufficient. In addition, the single-row receiving transfer conveyor robot connected to the faster speed obviously cannot keep up with the speed of three actions per mold. In order to meet the requirements of high-speed left and right alternating material output, a "left and right alternating stacking conveyor packing and sealing machine for containers and caps" was invented. It can be used for any specification and shape of package staggered arrangement. No matter how fast the speed, this invention can meet the requirements of stacking transmission, layer bagging heat sealing and automatic box picking, packing and sealing. It has subverted the traditional technology at home and abroad and achieved a breakthrough from zero to one. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a container and lid alternating left and right stacking conveying and sealing machine.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0005] A container and lid alternating stacking conveyor packaging unit includes a three-action thermoforming cup making machine. The three-action thermoforming cup making machine includes a sliding lower mold assembly for alternating forming, and two alternating stacking conveyor devices that respectively match the two lower molds of the sliding lower mold assembly. The middle part of the alternating stacking conveyor device is a conveying station, and stacking stations are provided on both sides of the conveying station. Unloading robots are provided above the unloading stations on both sides of the sliding lower mold assembly. The two unloading robots each correspond to one of the lower molds and are used to remove the formed products from the lower molds located at the unloading stations and stack them onto the alternating stacking conveyor devices. At the stacking station of the stacking conveyor, the left-right alternating stacking conveyor includes an upper alternating track and a lower alternating track. The upper alternating track is provided with two sets of left-right symmetrically arranged upper translation structures, and the lower alternating track is provided with two sets of left-right symmetrically arranged lower translation lifting structures. The two sets of upper translation structures correspond to the left and right stacking stations and slide on the conveying station and the corresponding stacking station. The two sets of lower translation lifting structures cooperate with the two sets of upper translation structures and slide alternately on the stacking station and the conveying station. Stacking material boxes are placed on both the upper translation structure and the lower translation lifting structure.

[0006] Specifically, the upper translation structure includes an upper sliding group and an upper second sliding group. The upper sliding group includes an upper sliding base plate and an upper driver. The upper driver is fixed to the side of the upper alternating track and drives the upper sliding base plate to slide. Below the upper sliding base plate, there are several upper sliders that match the upper alternating track. The upper sliders are symmetrically fixed on both sides of the lower surface of the upper sliding base plate and mounted on the upper alternating track. The upper surface of the upper sliding base plate has upper plate slide rails on both sides. The upper second sliding group includes an upper sliding plate and an upper second driver. The upper second driver is fixed to the side of the upper sliding plate and drives the upper sliding plate to slide in the upper plate slide rail. The bottom surface of the upper sliding plate has several symmetrically arranged upper second sliders. The upper second sliders are mounted on the upper plate slide rail. The upper sliding plate places and supports the receiving and stacking box.

[0007] Furthermore, the lower translational lifting structure includes a lower sliding group, a lower second sliding group, and a lower lifting structure. The lower sliding group includes a lower bottom sliding member and a lower actuator. The lower actuator is fixed on the lower alternating track and drives the lower bottom sliding member to slide on the lower alternating track. The lower bottom sliding member has a downwardly recessed groove in the middle. The top of the lower groove has lower flying plates mounted on the lower alternating track on both sides. The bottom surface of the lower flying plate has several symmetrically arranged lower sliding blocks that match the lower alternating track. The top surface of the lower flying plate has an upper well slide rail. The lower two sliding assembly includes a lower sliding member and a lower two driving force. The lower two driving force is fixed to the side of the lower sliding member and drives the lower sliding member to slide on the upper well slide rail. The middle part of the lower sliding member is provided with a lower two groove embedded in the lower groove. The top two sides of the lower two groove are mirrored with lower two flying plates mounted on the upper well slide rail. The bottom of the lower two flying plates is provided with a number of lower two sliding blocks that match the upper well slide rail. The lower lifting structure is fixed in the lower two groove and supports the lifting of the stacking box. The bottom of the stacking box is recessed into the lower two groove.

[0008] Furthermore, the lower lifting structure is configured as a lifting well structure to facilitate the accommodating and lifting of the stacked material box, including a first lifting seat and a second lifting seat. The second lifting seat is nested within the first lifting seat, and the first lifting seat is accommodated within the lower sliding member. The lower sliding member has lifting support platforms on both sides of the lower second flying plate. The lifting support platform has a first lifting toothed bar, which is nested within the lifting support platform and supports the first lifting seat. A first lifting driver is provided on one side of the lifting support platform. The first lifting driver drives a lifting gear shaft via a synchronous belt. The lifting gear shaft simultaneously drives the first lifting toothed bars in the lifting support platforms on both sides to lift the first lifting seat. A second lifting driver is fixed on the side of the first lifting seat. The second lifting driver drives the second lifting toothed bars located on both sides of the second lifting seat and drive the sidewalls of the first lifting seat. The second lifting toothed bars drive the second lifting seat to lift, and the second lifting seat supports the stacked material box.

[0009] Furthermore, the stacking bin is a multi-row limiting stacking bin, including a bin body and a cover. The cover covers the top of the bin body and includes several sets of single-row limiting stacking members arranged parallel to each other inside the bin body. The upper surface of the cover has a lifting window for the single-row limiting stacking members to extend to the outside. The upper surfaces of the second lifting seat and the upper sliding plate are each provided with a set of conveying grooves. The bottom of the stacking bin is provided with a set of conveying rails that match the conveying grooves. The bottom of the stacking bin is provided with rollers located between the set of conveying rails. The upper alternating track is provided with a conveying support plate in the middle of the side of the conveying direction of the conveying station. The conveying support plate and the rollers cooperate to make the stacking bin slide out onto the conveying support plate in the conveying direction of the conveying station.

[0010] Specifically, a receiving and transfer mechanical group matching the conveying station and a single-row whole-line stacking lateral conveying group are also provided. The single-row whole-line stacking lateral conveying group consists of two sets of single-row whole-line stacking lateral conveying devices placed one in front of the other. The relative positions of the single-row whole-line stacking lateral conveying devices and the conveying station are matched. The receiving and transfer mechanical group consists of two parallel, adjacent, mirror-arranged receiving and transfer robots. The two receiving and transfer robots are matched one-to-one with the two sets of single-row whole-line stacking lateral conveying devices.

[0011] Furthermore, the receiving and transfer robot includes a longitudinal translation mechanism, a lifting mechanism, a lateral translation mechanism, and a gripping mechanism. The longitudinal translation mechanism is located above the conveying station and extends above the single-row whole-piece stack lateral conveying group. The lifting mechanism is mounted on the longitudinal translation mechanism and is driven by the longitudinal translation mechanism to translate. The lateral translation mechanism is fixed below the lifting mechanism and drives the gripping mechanism to move to a position that matches the conveying station and the single-row whole-piece stack lateral conveying device to transfer the product from the conveying station to the single-row whole-piece stack lateral conveying device.

[0012] Specifically, it also includes a limited-position receiving, flipping, and lateral quantitative conveying device, an automatic loading and sealing robot, and a layer-by-layer conveying, bagging, and limiting heat-sealing device. The single-row, full-line stacking lateral conveying device transfers multiple rows of products placed on top to the limited-position receiving, flipping, and lateral quantitative conveying device via a side flip. The limited-position receiving, flipping, and lateral quantitative conveying device then transfers a fixed number of products to the layer-by-layer conveying, bagging, and limiting heat-sealing device. The automatic loading and sealing robot grabs unformed cartons from the carton storage mechanism, forms the cartons, and places them on the layer-by-layer conveying, bagging, and limiting heat-sealing device. The layer-by-layer conveying, bagging, and limiting heat-sealing device inserts inner bags into the cartons placed on it, then receives the products conveyed from the limited-position receiving, flipping, and lateral quantitative conveying device. After the cartons are loaded, the robot, in conjunction with the automatic loading and sealing robot, seals the cartons and then transports the sealed cartons to the outside.

[0013] Furthermore, the automatic loading and sealing robot includes a carton storage mechanism, a carton picking mechanism, a carton lid flipping mechanism, a carton bottom pressing mechanism, a carton bottom sealing mechanism, a conveyor line, a lid pressing mechanism, a carton sealing mechanism, and a packing mechanism. The carton storage mechanism is used to stack cartons. The carton picking mechanism, carton lid flipping mechanism, carton bottom pressing mechanism, and carton bottom sealing mechanism are all located on one side of the carton storage mechanism. The carton picking mechanism is used to pick up the stacked cartons on the carton storage mechanism one by one and flip the cartons from horizontal to vertical. The carton bottom pressing mechanism is located directly below the carton picking mechanism and is used to press and convey the carton bottom lids on the carton picking mechanism. The carton bottom sealing mechanism is located at one end of the carton bottom pressing mechanism. The system is used to seal the bottom cover of a carton. The carton cover flipping mechanism is located above the carton picking mechanism and is used to flip and correct the top cover of the carton on the bottom pressing mechanism. The conveyor line is located on one side of the bottom pressing mechanism and corresponds to it. It is used to receive and transport the cartons conveyed by the bottom pressing mechanism. The carton packing mechanism is located above the conveyor line and is used to grab the materials to be packed and put them into the empty cartons on the conveyor line. The capping mechanism is located on both sides of the conveyor line and is used to press the top cover of the carton on the conveyor line. The carton sealing mechanism is located above the conveyor line and parallel to the carton packing mechanism. It is used to seal the top cover of the carton pressed by the capping mechanism.

[0014] Furthermore, the layered conveying bagging and limiting heat-sealing device includes a first heat-sealing unit, a second heat-sealing unit, and a third heat-sealing unit. A roll of film is positioned above and below the rear of the first heat-sealing unit, and a receiving and conveying platform mechanism is positioned at the discharge station of the first heat-sealing unit. After the upper and lower layers of film, correspondingly drawn from the upper and lower rolls, are heat-sealed together in the first heat-sealing unit, the entire product presses against the film heat-sealing section, pulling the upper and lower layers of film into the feeding station of the first heat-sealing unit. A vertically lifting anti-scalding limiting gate is provided between the first heat-sealing unit and the receiving and conveying platform mechanism. The receiving and conveying platform mechanism is positioned between the second and third heat-sealing units. An adjusting device for adjusting the separation distance between the second and third heat-sealing units is provided between them. The second and third heat-sealing units each include a heat-sealing frame. The heat-sealing frame includes an upper and lower sealing mold that can move up and down to heat-seal the sides of the product, as well as a clutch frame that fixes the heat-sealing frame within it. Side heat-sealing cylinders are respectively installed above and below the heat-sealing frame, and these two side heat-sealing cylinders drive the upper and lower sealing molds to move together. The adjustment device includes at least two sets of positive and negative threaded screws and length adjustment rods, as well as at least one chain or synchronous belt. The two ends of the positive and negative threaded screws and the length adjustment rods are respectively connected to the clutch frames of the second and third heat-sealing units. One end of the length adjustment rod is driven to rotate by a motor, and the other end is equipped with a double gear. One gear meshes with the same set of positive and negative threaded screws, and the other gear is connected to the chain or synchronous belt to drive the other set of length adjustment rods to rotate. The other gear of the other set of length adjustment rods drives the same set of positive and negative threaded screws to achieve the required center distance.

[0015] Specifically, it also includes a sampling inspection structure that corresponds one-to-one with the unloading robot. The sampling inspection structure and the left-right alternating stacking conveyor are respectively arranged on both sides of the sliding lower module. The unloading robot moves in three layers longitudinally to correspond to the sampling inspection structure and the left-right alternating stacking conveyor.

[0016] The present invention has the following beneficial effects: (1) An independent unloading robot is set up above the unloading station to quickly connect the unloading station and the stacking station, thereby reducing the unloading stroke. At the same time, it can match the sampling structure on the other side, so that the sliding stroke of the unloading robot is effectively shortened, and the unloading stacking and unloading sampling rate is improved to meet the needs of rapid preparation of the three-station cup making machine.

[0017] (2) The bidirectional staggered left and right alternating stacking conveyor is adopted so that the products in the two unloading stations can be stacked in time. The upper and lower alternating method is adopted, and the upper translation structure and the lower translation lifting structure are grouped and grouped left and right. The products are staggered to the conveying station through the staggered conveying method, so as to meet the needs of rapid stacking of products and the convenience of subsequent conveying and stacking of products through the same conveying station.

[0018] (3) The detachable stacking box is adopted, so that the corresponding cover and single row of limiting stacking parts can be selected according to the actual products produced, so as to quickly adapt to the conveying and stacking of different products.

[0019] (4) Two transfer robots take turns receiving and transporting materials from the transfer station, achieving mutual avoidance during transportation, thereby greatly improving the transfer speed and ensuring that the product transfer speed of the single transfer station in the middle is always faster than the speed of the stacking station, ensuring that it can meet the transfer requirements of the two stacking stations stacking at the same time.

[0020] (5) It works in conjunction with an automatic loading and sealing robot to achieve fully automated operation of cartons. The structure is compact and beautiful, and the various mechanisms work intelligently and closely together, reducing the input of human labor, reducing production costs and improving production efficiency.

[0021] (6) The combined layer conveying bagging and limiting heat sealing device enables the products stacked in single rows and arranged in multiple rows to fit together tightly, and the overall products are compact, neat and beautiful after heat sealing. Attached Figure Description

[0040] The present invention will now be described in detail with reference to the accompanying drawings.

[0041] An embodiment of the present invention provides a container and lid alternating left-right stacking conveying and sealing machine unit, such as... Figure 1-9As shown, the invention includes a three-action thermoforming cup-making machine. The machine includes a sliding lower mold assembly for alternating forming and two left-right alternating stacking conveyor devices 2 that respectively match the two lower molds of the sliding lower mold assembly. The middle section of the left-right alternating stacking conveyor device is a conveying station C, and stacking stations B are provided on both sides of the conveying station C. Above the unloading stations A on both sides of the sliding lower mold assembly, there are unloading robots 1. Each of the two unloading robots 1 corresponds to one of the lower molds and is used to remove the formed products from the lower molds located at the unloading stations A and stack them onto the stacking stations B of the left-right alternating stacking conveyor device. The stacking conveyor 2 includes an upper alternating track 21 and a lower alternating track 24. The upper alternating track 21 has two sets of symmetrically arranged upper translational structures 23, and the lower alternating track 24 has two sets of symmetrically arranged lower translational lifting structures 25. The two sets of upper translational structures 23 correspond to the two left and right stacking stations B and slide on the conveying station C and the corresponding stacking station B. The two sets of lower translational lifting structures 25 cooperate with the two sets of upper translational structures 23 and slide alternately between the stacking station B and the conveying station C. Stacking boxes 26 are placed on both the upper translational structures 23 and the lower translational lifting structures 25. Two sets of unloading robots 1 correspond to the two lower molds respectively, forming alternating unloading. The two stacking stations B of the left and right alternating stacking conveyor 2 are used to stack the two sets of unloading robots 1, thereby improving the unloading speed of the sliding lower mold group and ensuring the working efficiency of the three-action thermoforming cup making machine equipped with the sliding lower mold group. In addition, it includes a sampling structure 11 corresponding to the unloading robot 1. The sampling structure 11 and the left-right alternating stacking conveyor 2 are respectively arranged on both sides of the sliding lower module. The unloading robot 1 moves longitudinally in three layers, corresponding to the sampling structure 11 and the left-right alternating stacking conveyor 2. Through the forward and reverse displacement of the unloading robot 1, rapid sampling or rapid unloading operations are achieved. At the same time, two sets of upper translation structures 23 and two sets of lower translation lifting structures 25 are matched one-to-one to achieve the purpose of alternating up and down. This ensures that after a stacking bin 26 is full, a new stacking bin 26 can be quickly replaced for stacking, avoiding the defect of not being able to stack due to the cup making speed being too fast.

[0042] Specifically, the upper translation structure 23 includes an upper sliding group and an upper second sliding group. The upper sliding group includes an upper sliding base plate 2303 and an upper driver 2301. The upper driver 2301 is fixed to the side of the upper alternating track 21 and drives the upper sliding base plate 2303 to slide. Below the upper sliding base plate 2303 are several upper sliders 2302 that match the upper alternating track 21. The upper sliders 2302 are symmetrically fixed on both sides of the lower surface of the upper sliding base plate 2303 and mounted on the upper alternating track 21. The upper sliding base plate 2303 has upper plate slide rails 2304 on both sides of its upper surface. The upper two slide groups include an upper sliding plate 2306 and an upper two drive 2305. The upper two drive 2305 is fixed to the side of the upper sliding plate 2306 and drives the upper sliding plate to slide in the upper plate slide rail 2304. The bottom surface of the upper sliding plate 2306 has several symmetrically arranged upper two sliders 2307. The upper two sliders 2307 are mounted on the upper plate slide rail 2304. The upper sliding plate 2306 places and supports the receiving and stacking box 26.

[0043] Furthermore, the lower translational lifting structure 25 includes a lower sliding group, a lower second sliding group, and a lower lifting structure. The lower sliding group includes a lower bottom sliding member 2502 and a lower driver 2501. The lower driver 2501 is fixed on the lower alternating track 24 and drives the lower bottom sliding member 2502 to slide on the lower alternating track 24. The lower bottom sliding member 2502 has a downwardly recessed groove in the middle. The top of the lower groove is provided with lower flying plates 2503 mounted on the lower alternating track 24 on both sides. The bottom surface of the lower flying plate is provided with several symmetrically arranged lower sliding blocks 2504 that match the lower alternating track 24. The top surface of the lower flying plate is provided with an upper well slide rail 2505. The lower second sliding group... The device includes a lower sliding member 2507 and a lower second driver 2506. The lower second driver 2506 is fixed to the side of the lower sliding member 2507 and drives the lower sliding member 2507 to slide on the upper well slide rail 2505. The lower sliding member 2507 has a lower second groove embedded in the lower groove in the middle. The top two sides of the lower second groove are mirrored with lower second flying plates 2509 mounted on the upper well slide rail 2505. The bottom of the lower second flying plates 2509 is provided with a plurality of lower second sliders 2510 that match the upper well slide rail 2505. The lower lifting structure is fixed in the lower second groove and supports the lifting of the receiving stack box 26. The bottom of the receiving stack box 26 is embedded in the lower second groove. The lower lifting structure is used to lift the stacking box 26 placed on the lower lifting structure to the corresponding stacking station B position to ensure the smooth stacking. That is, the height of the stacking box 26 after being lifted by the lower lifting structure is the same as the height of the stacking box 26 placed on the upper translation structure 23, and they are at the same horizontal position.

[0044] Furthermore, the lower lifting structure is configured as a lifting shaft structure to facilitate the accommodating and lifting of the receiving and stacking bin 26, including a first lifting seat 2511 and a second lifting seat 2515. The second lifting seat 2515 is nested within the first lifting seat 2511. The first lifting seat 2511 is accommodated within the lower sliding member 2507. The lower sliding member 2507 has lifting support platforms 2508 on both sides of the lower second flying plate 2509. A first lifting toothed bar 2512 is provided in the lifting support platform 2508, nested within the lifting support platform 2508 and supporting the first lifting seat 2511. A second lifting toothed bar 2512 is provided on one side of the lifting support platform 2508. A lifting driver 2513 drives a lifting gear shaft 2514 via a synchronous belt. The lifting gear shaft 2514 simultaneously drives the first lifting toothed bars 2512 in the lifting support platforms 2508 on both sides to raise and lower the first lifting seat 2511. A second lifting driver 2517 is fixed on the side of the first lifting seat 2511. The second lifting driver 2517 drives the second lifting toothed bars 2516, which are arranged on both sides of the second lifting seat 2515 and drive the side walls of the first lifting seat 2511. The second lifting toothed bars 2516 drive the second lifting seat 2515 to rise and fall. The second lifting seat 2515 supports the receiving and stacking box 26. Both the upper translation structure 23 and the lower translation and lifting structure 25 adopt a two-stage horizontal translation design. Since they only slide on two workstations, the two-stage horizontal translation design can complete the corresponding translation requirements. The lower lifting structure adopts a three-stage lifting method, which realizes the purpose of quickly lifting the receiving stack box 26 on the lower lifting structure. The lifting is carried out by using a lifting toothed bar. The meshing force between the lifting toothed bar and the gear ensures stable support for the receiving stack box 26 during the rapid lifting process, effectively ensuring the stability of receiving materials.

[0045] Furthermore, the stacking bin 26 is a multi-row limiting stacking bin 26, including a bin body 2601 and a cover 2602. The cover 2602 covers the top of the bin body 2601. It also includes several sets of single-row limiting stacking members arranged parallel and adjacent to each other within the bin body 2601. The upper surface of the cover 2602 has a lifting window for the single-row limiting stacking members to extend to the outside. The second lifting seat 2515 and the upper sliding plate 2306 each have a set of conveying grooves 2603 on their upper surfaces. The bottom of the stacking bin 26 is provided with a set of conveying rails 2604 that match the conveying chute 2603. Rollers 2605 are located at the bottom of the stacking bin 26 between the set of conveying rails 2604. A conveying support plate 22 is located in the middle of the upper alternating track 21 on one side of the conveying direction of the conveying station C. The conveying support plate 22 and the rollers 2605 cooperate to allow the stacking bin 26 to slide onto the conveying support plate 22 in the conveying direction of the conveying station C. The bin body 2601 and the cover 2602 are separated, and a single row of limiting stacking components is fixed to the bottom of the cover 2602 via connectors. This allows for easy replacement of the stacking assembly of the corresponding product by simply removing the top cover of the stacking bin 26 when changing products.

[0046] Specifically, the system also includes a receiving and transfer mechanical group matching the conveying station C, and a single-row, full-length stacking lateral conveying group. The single-row, full-length stacking lateral conveying group consists of two sets of single-row, full-length stacking lateral conveying devices 4 placed one behind the other. The relative positions of the single-row, full-length stacking lateral conveying devices 4 and the conveying station C are matched. The receiving and transfer mechanical group consists of two parallel, adjacent, mirror-aligned receiving and transfer robots 3, each matched one-to-one with one of the two sets of single-row, full-length stacking lateral conveying devices 4. This one-to-one matching arrangement of the two sets of receiving and transfer robots 3 with the single-row, full-length stacking lateral conveying devices 4 allows for alternating material handling, enabling faster removal of products from the conveying station C. Furthermore, the alternating handling method, where adjacent rows of products are gripped by two separate receiving and transfer robots 3, allows for staggered arrangement of products, effectively improving the utilization rate of the sheet material.

[0047] Furthermore, the receiving and transfer robot 3 includes a longitudinal translation mechanism 31, a lifting mechanism 32, a lateral translation mechanism 33, and a gripping mechanism 34. The longitudinal translation mechanism is located above the conveying station C and extends above the single-row whole-piece stacking lateral conveying group. The lifting mechanism 32 is mounted on the longitudinal translation mechanism 31 and is driven by the longitudinal translation mechanism 31 to translate. The lateral translation mechanism 33 is fixed below the lifting mechanism 32 and drives the gripping mechanism 34 to move to a position that matches the conveying station C and the single-row whole-piece stacking lateral conveying device 4 to transfer the product from the conveying station C to the single-row whole-piece stacking lateral conveying device 4. The lateral translation mechanism 33 of the robotic arm enables the gripping mechanism 34, which was originally mismatched with the unloading and sampling station due to its parallel and adjacent arrangement, to be directly matched with the unloading and sampling station after the lateral translation mechanism. At the same time, it also enables the gripping mechanisms 34 of the two material receiving transfer robotic arms 3 to avoid each other, avoid collisions during operation, and improve the efficiency of product production.

[0048] Specifically, it also includes a limiting receiving, flipping, and translating transverse quantitative conveying device 5, an automatic loading and sealing robot 6, and a layered conveying, bagging, limiting, and heat-sealing device 7. The single-row, whole-line stacking lateral conveying device 4 transfers the single-row, multi-column products placed on top to the limiting receiving, flipping, and translating transverse quantitative conveying device 5 via lateral flipping. Then, the limiting receiving, flipping, and translating transverse quantitative conveying device 5, after stacking a fixed number of products, transfers them to the layered conveying, bagging, limiting, and heat-sealing device 7. The automatic loading and sealing robot 6... The packing robot 6 picks up an unformed carton from the carton storage mechanism 61, forms the carton, and places it on the layer conveying bagging and limiting heat sealing device 7. The layer conveying bagging and limiting heat sealing device 7 inserts an inner bag into the carton placed on it, then receives the product conveyed from the limiting receiving flipping and transverse quantitative conveying device 5. After the carton is loaded, it cooperates with the automatic loading and sealing robot 6 to seal the carton and then transports the sealed carton to the outside.

[0049] Furthermore, the automatic loading and sealing robot 6 includes a carton storage mechanism 61, a carton picking mechanism 62, a carton lid flipping mechanism 63, a carton bottom pressing mechanism 64, a carton bottom sealing mechanism 65, a conveyor line 66, a lid pressing mechanism 67, a carton sealing mechanism 68, and a packing mechanism 69. The carton storage mechanism 61 is used to stack cartons. The carton picking mechanism 62, the carton lid flipping mechanism 63, the carton bottom pressing mechanism 64, and the carton bottom sealing mechanism 65 are all located on one side of the carton storage mechanism 61. The carton picking mechanism 62 is used to pick up the stacked cartons on the carton storage mechanism 61 one by one and flip the cartons from horizontal to vertical. The carton bottom pressing mechanism 64 is located directly below the carton picking mechanism 62 and is used to press and convey the carton bottom lid on the carton picking mechanism 62. The carton bottom sealing mechanism 65 is located below the carton bottom pressing mechanism. At one end of 64, a mechanism for sealing the bottom cover of a carton is used. The carton cover flipping mechanism 63 is located above the carton picking mechanism 62 and is used to flip and correct the top cover of the carton on the bottom pressing mechanism 64. The conveyor line 66 is located on one side of the bottom pressing mechanism 64 and corresponds to the bottom pressing mechanism 64. It is used to receive and convey the cartons conveyed by the bottom pressing mechanism 64. The carton packing mechanism 69 is located above the conveyor line 66 and is used to grab the materials to be packed and put them into the empty cartons on the conveyor line 66. The capping mechanism 67 is located on both sides of the conveyor line 66 and is used to press the top cover of the carton on the conveyor line 66. The carton sealing mechanism 68 is located above the conveyor line 66 and parallel to the carton packing mechanism 69. It is used to seal the top cover of the carton pressed by the capping mechanism 67.In actual operation, each mechanism is activated by receiving a signal. First, the folded cartons are placed on the carton storage mechanism 61 for later use. Then, the carton picking mechanism 62, the bottom pressing mechanism 64, the bottom sealing mechanism 65, and the lid flipping mechanism 63 rise. After rising, the carton picking mechanism 62 moves directly to the carton storage mechanism 61 and picks up the cartons one by one. After picking up the cartons, it moves back to its original position and flips them, changing the cartons from horizontal to vertical to facilitate unfolding. Then, the bottom pressing mechanism 64 presses the unfolded bottom lid of the cartons together, while the lid flipping mechanism 63 flips the top lid of the cartons outward and corrects the forming position of the cartons, so that the bottom lids can be more neatly aligned and pressed. The bottom pressing mechanism 64 then conveys the cartons to the conveyor line 66, while the bottom sealing machine... The sealing mechanism 65 performs the carton sealing operation. As the carton moves, the bottom of the carton is sealed. The conveyor line 66 is responsible for conveying the carton forward. When the carton is conveyed to the capping mechanism 67, the packing mechanism 69 picks up the materials to be packed and places them into the empty carton. When the carton is full, the capping mechanism 67 presses the top cover of the carton and moves with the pressed carton. At the same time, the carton sealing mechanism 68 seals the top cover of the carton. The lid flipping mechanism 63, the bottom pressing mechanism 64, and the bottom sealing mechanism 65 will first follow the carton picking mechanism 62 to rise and grab the carton. After the carton is assembled, they will return to their original positions. At this time, the bottom pressing mechanism 64 will be on the same horizontal plane as the conveyor line 66, which is convenient for the carton to be conveyed onto the conveyor line 66.

[0050] Furthermore, the layer-by-layer conveying and limiting heat-sealing device 7 includes a first heat-sealing unit 71, a second heat-sealing unit 74, and a third heat-sealing unit 75. A roll of film 72 is disposed above and below the rear of the first heat-sealing unit 71, and a receiving and conveying platform mechanism 73 is disposed at the discharge station of the first heat-sealing unit 71. After the upper and lower layers of film correspondingly drawn from the upper and lower rolls of film 72 are aligned and heat-sealed by the first heat-sealing unit 71, the entire product presses against the film heat-sealing part, pulling the upper and lower layers of film into the feeding station of the first heat-sealing unit 71. A vertical lifting anti-scalding limit is provided between the first heat-sealing unit 71 and the receiving and conveying platform mechanism 73.

The positive and negative threaded screws and length adjusting rods are connected at both ends to the clutch frames of the second heat-sealing unit 74 and the third heat-sealing unit 75, respectively. One end of the length adjusting rod is driven to rotate by a motor, and the other end is equipped with a double gear. One gear meshes with the same set of positive and negative threaded screws, and the other gear is connected to the chain or synchronous belt to drive the other set of length adjusting rods to rotate. The other gear of the other set of length adjusting rods drives the same set of positive and negative threaded screws to achieve the required center distance. It also includes a layered unloading tray and a lifting and translating mechanism for unloading products on the layered unloading tray. The system includes a pushing mechanism and a sliding seat for sliding the unloading tray along the guide rail. Guardrails are installed on both sides of the unloading tray to limit the conveyed products at both ends and prevent scattering. A slider is installed at the rear of the unloading tray and slides along the guide rail of the sliding seat to form a sliding pair for the unloading tray. A film guide plate is fixed to the front of the unloading tray and a pulley is installed to prevent damage to the film and to ensure that the unloading tray, away from the guide rail pulley, can press down on the lower layer of film and slide on the receiving and conveying platform without being suspended. A translation motor is installed at the bottom of the sliding seat to drive the unloading tray independently, cooperating with the unloading tray sliding pair to drive the unloading tray to slide to the designated position according to the controller command.The upper and lower films, drawn from the upper and lower positions of the roll film 72 at the rear and front bottom positions of the first heat-sealing unit 71, are heat-sealed together at the mold closing point in the middle of the first heat-sealing unit 71 by the film roller 2605 to form the front heat seal of the product to be packaged. The product to be packaged moves forward against the front heat-sealed part of the upper and lower films, passing through the heat-sealing mold closing point from the feeding station of the first heat-sealing unit 71 to its discharge station, and enters the receiving and conveying platform between the second heat-sealing unit 74 and the third heat-sealing unit 75. During the forward movement, the upper film drawn from the upper roll film 72 covers the top of the product, and the lower film drawn from the lower roll film 72 is located below the product. After the product has completely entered the receiving and conveying platform, the first heat-sealing unit 71 heat-seales the upper and lower films again to complete the rear heat seal of the product. Then the receiving and conveying platform reaches the designated station, and the second heat-sealing unit 74 and the third heat-sealing unit 75 perform double-sided heat sealing on the product, thus completing the four-sided heat-sealing packaging of the product. The heat-sealing part at the rear end of the product is disconnected, which on the one hand completes the heat sealing of the rear end of the product and disconnects it from the packaging film of the next set of products to be packaged, and on the other hand simultaneously forms the heat sealing of the front end of the next set of products to be packaged.
