Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly to a linear unpacking, loading and sealing integrated machine. Background Art

[0002] In the carton packaging process, product sorting and carton forming are the most important essential conditions. The sorted products are put into the carton manually or by a mechanism, and then accessories such as partition boards and certificates of conformity are put in, and the carton is sealed with tape to complete the packaging process. Product sorting means sorting the products to be put into the carton in a single layer arrangement; the carton needs multiple processes to be folded from a sheet blank into a box shape, corresponding to multiple mechanical actuators and corresponding motion mechanisms to complete the work of forming the carton into a square and sealing the bottom, putting in the bottom partition board, then putting the sorted products into the carton, putting in the top partition board and the certificate of conformity, folding the top page of the carton, and sealing the carton with tape.

[0003] In the existing packaging production line equipment, the carton needs to be opened, its bottom sealed, then the bottom partition board put in, and then products, top partition board and certificate of conformity are loaded into the box body, and finally the top and bottom of the box body are sealed. Multiple types of unpacking, loading and sealing integrated machines for cartons have been proposed in the prior art. For example, the fully automatic unpacking, loading and sealing integrated machine proposed in the Chinese invention application with the publication number "CN109229568A" realizes a series of processes from opening the box, putting in the partition board, loading the products into the box, putting in the certificate of conformity to finally sealing the box.

[0004] However, the existing unpacking, loading and sealing integrated machines are derived from vertical unpacking machines, and the method of adopting a 90° side entry of consumables for expanding the packaging function structure related to cartons results in a simple piecing together of function structures, unable to have a reasonable space layout, occupying a large area, especially a large width, and the conflict between adding consumables and people and the logistics channel, which is not convenient to be arranged in a relatively narrow and long workshop with multiple production lines arranged side by side. Therefore, improvement is needed. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a linear unpacking, loading and sealing integrated machine that is linearly arranged, has a more compact structure and a smaller volume, so as to be conveniently arranged in a smaller and relatively narrow and long workshop, and in which each mechanism adopts a compact design and has a high integration degree.

[0006] The present application proposes a linear unpacking, loading and sealing integrated machine. Because the carton packaging function mechanisms are linearly arranged, it is also called a linear unpacking, loading and sealing integrated machine.

[0007] The linear opening, packing and sealing integrated machine of the present invention comprises a box-type frame, a material sorting system, an industrial robot, a carton opening system and a carton sealing system. The carton opening system comprises a carton storage unit and a carton opening unit. The material sorting system, the industrial robot, the carton opening unit and the carton sealing system are all installed in the box-type frame. The carton opening system and the carton sealing system are arranged on one side of the box-type frame along a straight line, and the material sorting system and the industrial robot are arranged on the other side of the box-type frame along a straight line. The two straight lines are parallel, and the feed ports of the carton storage unit and the material sorting system are arranged on the outer wall of the same side of the box-type frame. The vertical unpacking mechanism and the supporting mechanism of the carton unpacking department cooperate to open the carton. The material sorting system arranges multiple materials into a single layer through the box-type material sorting mechanism. The industrial robot puts the single-layer material into the carton through the vacuum adsorption type handling mechanism. The sealing system drives the accessory delivery suction cup through the synchronous belt type double-stroke mechanism to put the accessory into the carton. The sealing mechanism of the sealing system packs the carton and closes it and then outputs it to the box frame. The material sorting system, unpacking system and sealing system all adopt a compact structure. When working, the material sorting system uses the box-type material sorting mechanism to make the box in the whole material sorting process The single-layer material is neatly arranged and has the smallest cross-sectional area, which is convenient for the vacuum adsorption transport mechanism to adsorb and grab the carton. The vertical unpacking mechanism of the unpacking system grabs the carton at the carton storage part and unfolds the long and short sides of the carton during the movement. The unpacking system props up the two sets of long and short folding pages of the carton through the carton supporting mechanism, which makes it convenient for the robot to put the single-layer material into the carton through the vacuum adsorption transport mechanism. The synchronous belt double-stroke mechanism of the sealing system drives the accessory delivery suction cup to put the product manual, upper and lower partitions, lining and other accessories into the carton. In the box, the sealing mechanism of the carton sealing system folds the carton in half, aligns the long and short pages, seals them, and then outputs them to the box frame. The sealing mechanism of the carton sealing system is existing technology and will not be described here. The linear opening, packaging and sealing all-in-one machine arranges the conveying routes of cartons and materials on two parallel lines respectively. Compared with the traditional vertical feeding opening, packaging and sealing all-in-one machine, it has a more compact structure and smaller size, which makes it convenient to arrange it in smaller and narrower workshops. The compact and optimized design of the material sorting system, carton opening system and carton sealing system further improves the integration of the all-in-one machine and reduces the size.

[0008] Preferably, the material sorting system includes a box-type material sorting mechanism. The box-type material sorting mechanism includes a feeding belt, a material cutting component, a material pushing component, a sorting table, and a surrounding plate component. The input end of the feeding belt is arranged on the side wall of the box-type frame. The material cutting component is arranged at the rear end of the middle part of the feeding belt. The material cutting component is used to separate the material boxes filled in a single row from the material boxes in the front part of the feeding belt. The material pushing component is installed on the outer side of the rear section of the feeding belt. The sorting table is installed on the inner side of the rear section of the feeding belt. The surrounding plate component is installed on the sorting table. The material pushing component pushes the single-row material boxes on the rear section of the feeding belt onto the sorting table. The surrounding plate component cooperates with the material pushing component to constrain the multiple single-row material boxes on four sides and sort them into a square single layer of materials. The driving cylinder of the material pushing component is arranged on the sorting table to reduce the occupied space. The material boxes are linearly transported and sorted. The material pushing component and the surrounding plate component constrain the material boxes during the sorting process, making the single-layer materials sorted into a square shape with the smallest cross-sectional area, which is convenient for being adsorbed and grabbed into the box by the vacuum adsorption type handling mechanism. Arranging the driving cylinder of the material pushing component on the sorting table realizes a compact design and is beneficial to reducing the overall space volume of the equipment.

[0009] Preferably, the vacuum adsorption type handling mechanism includes a connecting frame, a sponge suction cup, and a detection component. The connecting frame is connected to the industrial robot. The sponge suction cup is installed at the lower part of the connecting frame. A vacuum generator is arranged in the sponge suction cup. The sponge suction cup generates vacuum to adsorb the material boxes sorted into a single layer. The detection component is used to detect whether the materials fall off. By using a sponge suction cup instead of a matrix-type rubber suction cup group, the structure is simple and compact, saving space and cost. It can absorb materials with uneven heights. The whole sponge does no harm to the material packaging. The adsorption vacuum degree is high and the adsorption force is large. By using the detection component, it can be found in time when the materials fall off.

[0010] Preferably, the vertical box-opening mechanism and the carton storage part are arranged in a straight line. The vertical box-opening mechanism includes a slide rail assembly, a slide table assembly, a servo motor assembly I, a short side component, a short flap bending component, and a long side component. The slide rail assembly is installed in the box-type frame. The servo motor assembly I drives the slide table assembly to move along the slide rail assembly, so that the slide table assembly connects the carton storage part and the case-sealing system. The short side component and the long side component are rotatably installed on the slide table assembly in a concentric double-axis manner, thus reducing the volume. Matrix suction cup groups are arranged on both the short side component and the long side component. The two matrix suction cup groups are respectively used to adsorb the short side and the long side of the carton. The short side component and the long side component cooperate to unfold the short side and the long side of the carton. The short flap bending component is installed on the short side component and is used to bend the short flap at the rear of the bottom of the carton. The servo motor assembly I drives the slide table assembly to move along the slide rail assembly to the carton storage part, so that the suction cup group on the short side component adsorbs the short side of the carton. The servo motor assembly I drives the slide table assembly to move towards the case-sealing system. During the movement, the short side component and the long side component cooperate to unfold the end side and the long side of the carton to form the carton. The short flap bending component bends the short flap at the rear of the bottom of the carton inwards. The remaining short flaps of the carton are bent inwards and sealed by the case-sealing system during the movement of the carton, so that the carton can carry materials. The mechanism in the case-sealing system for bending and sealing the short flaps at the bottom of the carton is the prior art and will not be elaborated here.

[0011] Preferably, two box-supporting mechanisms are provided. The two box-supporting mechanisms are respectively arranged at the diagonals of the unfolded carton. The box-supporting mechanism includes a mounting plate, a support plate, bevel gears, support plates, a swing arm assembly, and a box-supporting cylinder. The mounting plate is provided with a long guide groove. The support plate is adjustably installed on the long guide groove of the mounting plate. The rotating shafts of the two bevel gears are rotatably installed on the support plate. The two bevel gears are meshed. The two support plates are respectively installed at one ends of the rotating shafts of the two bevel gears. The outer ends of the two support plates are close to each other. The box-supporting cylinder is installed on the support plate. The piston rod of the box-supporting cylinder drives the rotation of one bevel gear through the swing arm assembly. The two support plates respectively drive the short flaps and the long flaps at the upper diagonal corners of the carton to open under the drive of the two bevel gears. After the carton is unfolded by the vertical box-opening mechanism, the piston rod of the box-supporting cylinder drives the rotation of one bevel gear through the swing arm assembly. The two support plates respectively drive the short flaps and the long flaps at the upper diagonal corners of the carton to open outwards, facilitating the vacuum adsorption type handling mechanism to put the single-layer material box into the carton. After the packing is completed, the box-supporting cylinder drives the two bevel gears to flip through the swing arm assembly, so that the two support plates bend the short flaps inwards into the carton, facilitating subsequent case-sealing. Compared with the traditional long-axis series flipping box-supporting mechanism and the flared mouth lifting box-supporting mechanism, this box-supporting mechanism is driven by a cylinder, has a compact structure, a small volume, and a low cost. Adjusting the position of the support plate along the long guide groove of the mounting plate can be applicable to cartons of different lengths.

[0012] Preferably, the synchronous belt type double-stroke mechanism includes a fixed plate, a connecting piece, a first-stage slide, a second-stage slide, a synchronous belt assembly, and a servo motor assembly II. The fixed plate is installed at the front of the carton sealing system. The connecting piece is fixedly installed on the fixed plate. The first-stage slide is slidably installed on the fixed plate. The second-stage slide is slidably installed on the first-stage slide. The second-stage slide is used to install the accessory suction cup assembly. The accessory suction cup assembly is used to adsorb and grab accessories. The second-stage slide and the first-stage slide slide in the same direction. The synchronous belt assembly is installed on the connecting piece. The lower belt of the synchronous belt assembly is connected to the connecting piece. The upper belt of the synchronous belt assembly is connected to the second-stage slide. The servo motor assembly II drives the second-stage slide to rotate. When the synchronous belt assembly rotates, it drives the fixed plate and the connecting piece to move backward and at the same time drives the second-stage slide to move forward, doubling the stroke of the second-stage slide and reducing the volume. Through the above settings, the stroke of the second-stage slide is doubled, thus achieving a compact design and reducing the volume. The second-stage slide drives the accessory suction cup to grab the accessory and put it into the carton. The accessory suction cup assembly is a prior art and will not be elaborated here.

[0013] Preferably, the carton sealing system is provided with left and right opposed conveyor belts as the conveying mechanism. The left and right opposed conveyor belts respectively clamp both sides of the carton and convey it backward. The left and right opposed conveyor belts of the carton sealing system are connected by a plurality of lead screws and guide compound adjustment mechanisms and the width is adjusted. The lead screw and guide compound adjustment mechanism includes a round tube, a sliding sleeve block, a lead screw, and a threaded sleeve. Two long slot holes are provided on the side wall of the round tube. Two sliding sleeve blocks are slidably sleeved on the outer wall of the round tube. The left and right conveyor belts of the carton sealing system are respectively connected to the two sliding sleeve blocks. The lead screw is concentrically and rotatably installed in the round tube. Positive and negative threads are respectively provided at both ends of the lead screw. Two threaded sleeves are respectively threadedly connected to the positive and negative threads of the lead screw. Two threaded sleeves are respectively connected to the two sliding sleeve blocks through connecting pieces passing through the two long slot holes of the round tube. By rotating the lead screw, under the action of the positive and negative threads, the two threaded sleeves drive the two sliding sleeve blocks to approach or separate, adjusting the width of the carton sealing system. Through the above settings, rotating the lead screw can conveniently adjust the width and spacing of the left and right opposed conveyor belts of the carton sealing system, so as to convey cartons of different widths. The lead screw and guide compound adjustment mechanism uses the round tube as the guide, and the lead screw provides the driving force. By selecting a suitable lead screw form, adjustment methods such as single-direction and two-way centering can be achieved, greatly reducing the volume of the traditional lead screw + guide structure, having both rigidity and guidance, and being particularly suitable for small-sized integrated equipment.

[0014] Preferably, it further includes a plurality of sprockets. The plurality of sprockets are concentrically installed on the plurality of lead screws. The plurality of sprockets are connected by chain drive and are used to drive the plurality of lead screws simultaneously. Through the cooperation of the plurality of sprockets and the chain, the plurality of lead screws are synchronously connected to achieve the purpose of synchronous adjustment and simplify the operation.

[0015] Preferably, it further includes a plurality of heavy-load adjustable-height support mechanisms, which are installed at the bottom of the box-type frame for supporting the box-type frame and adjusting the height of the box-type frame from the ground; it is convenient to level the equipment, clean the bottom of the equipment, and facilitate the insertion of lifting cables during handling.

[0016] Preferably, the heavy-load adjustable-height support mechanism includes an outer sleeve seat, an inner sleeve, a support plate, a threaded block, and a screw rod. The inner sleeve is slidably inserted into the outer sleeve seat, and the outer sleeve seat vertically limits and guides the inner sleeve. The support plate is installed at the top of the inner sleeve and is connected to the box-type frame. The threaded block is installed on the support plate, and the screw rod is rotationally screwed with the threaded block. The lower end of the screw rod contacts the bottom of the outer sleeve seat, and the upper end of the screw rod extends above the support plate. By rotating the screw rod, the screw rod drives the support plate to lift through the threaded block, thereby adjusting the height of the box-type frame from the ground; through the sliding socket connection of the outer sleeve seat and the inner sleeve, the guiding strength is high, it can bear strong dynamic load impacts, can withstand heavy loads, has a simple structure, and low cost.

[0017] The beneficial effects of the present invention are as follows: 1. During operation, the material sorting system enables the boxes to be in a controlled and constrained state throughout the material sorting process through the box-type material sorting mechanism. The single-layer materials are sorted neatly and have the smallest cross-sectional area, which is convenient for being adsorbed and grabbed into the box by the vacuum adsorption type handling mechanism; the vertical box-opening mechanism of the box-opening system grabs the cardboard box at the cardboard box storage part and unfolds the long side and short side of the cardboard box during the moving process. The box-opening system props up the two groups of long and short folding pages of the cardboard box through the box propping mechanism, which is convenient for the manipulator to put the single-layer materials into the cardboard box through the vacuum adsorption type handling mechanism. The synchronous belt type double-range mechanism of the box-sealing system drives the accessory delivery suction cup to put accessories such as product manuals, upper and lower partitions, and liners into the cardboard box, and the sealing mechanism of the box-sealing system seals the long and short pages of the cardboard box that are folded and aligned and then outputs the box-type frame; 2. For this linear unpacking, loading, and sealing integrated machine, the conveying routes of the cardboard box and the materials are respectively arranged on two parallel lines, which is more compact and smaller in volume than the traditional unpacking, loading, and sealing integrated machine with vertical feeding. Therefore, it is convenient to be arranged in a smaller and narrower workshop. The material sorting system, box-opening system, and box-sealing system that have been compactly optimized further improve the integration degree of the integrated machine and reduce the volume. 3. All functional structures are installed and fixed on the box-type frame structure. The peripheral protection is made of transparent tempered glass, and the operation door is also made of transparent tempered glass. A white atomized film is pasted at a certain height from the installation plane, which is not only convenient for observing the operation status of the equipment but also blocks the exposed parts of non-essential equipment; the box-type structure has high strength, can meet the hoisting of the whole machine equipment, and is superior to the loose decorative protection structures of similar equipment.

The connecting frame 301 is connected to the industrial robot 3. The sponge suction cup 302 is installed at the lower part of the connecting frame 301. A vacuum generator is arranged in the sponge suction cup 302. The sponge suction cup 302 generates vacuum to adsorb the material boxes arranged in a single layer. The detection component 303 is used to detect whether the materials fall off. The sealing system 5 is provided with left and right opposed conveyor belts as a conveying mechanism. The left and right opposed conveyor belts respectively clamp both sides of the carton and convey it backward. The left and right opposed conveyor belts of the sealing system 5 are connected to an adjusting mechanism that combines a lead screw and a guide through a plurality of lead screws, and the width is adjusted. The adjusting mechanism that combines the lead screw and the guide includes a round tube 511, a sliding sleeve block 512, a lead screw 513 and a threaded sleeve 514. Two long slot holes are arranged on the side wall of the round tube 511. Two sliding sleeve blocks 512 are slidably sleeved on the outer wall of the round tube 511. The left and right conveyor belts of the sealing system 5 are respectively connected to the two sliding sleeve blocks 512. The lead screw 513 is concentrically and rotatably installed in the round tube 511. Positive and negative threads are respectively arranged at both ends of the lead screw 513. Two threaded sleeves 514 are respectively threadedly connected to the positive and negative threads of the lead screw 513. The two threaded sleeves 514 are respectively connected to the two sliding sleeve blocks 512 through connectors passing through the two long slot holes of the round tube 511. By rotating the lead screw 513, under the action of the positive and negative threads, the two threaded sleeves 514 drive the two sliding sleeve blocks 512 to approach or separate, so as to adjust the width of the sealing system 5. It also includes a plurality of sprockets 515. The plurality of sprockets 515 are concentrically installed on the plurality of lead screws 513. The plurality of sprockets 515 are connected by chain drive to simultaneously drive the plurality of lead screws 513. It also includes a plurality of heavy-duty adjustable height support mechanisms. The plurality of heavy-duty adjustable height support mechanisms are installed at the bottom of the box-type frame 1 to support the box-type frame 1 and adjust the ground clearance height of the box-type frame 1. The heavy-duty adjustable height support mechanism includes an outer sleeve seat 101, an inner sleeve 102, a support plate 103, a threaded block 104 and a screw rod 105. The inner sleeve 102 is slidably inserted into the outer sleeve seat 101. The outer sleeve seat 101 vertically limits and guides the inner sleeve 102. The support plate 103 is installed at the top of the inner sleeve 102. The support plate 103 is connected to the box-type frame 1. The threaded block 104 is installed on the support plate 103. The screw rod 105 is rotationally screwed to the threaded block 104. The lower end of the screw rod 105 contacts the bottom of the outer sleeve seat 101.

By rotating the screw rod 105, the screw rod 105 drives the support plate 103 to lift through the threaded block 104, so as to adjust the ground clearance height of the box-type frame 1.

[0034] During operation, the material sorting system 2 keeps the boxes under controlled restraint throughout the sorting process through the box sorting mechanism. The single-layer materials are sorted into a square shape with the smallest cross-sectional area, which is convenient for being adsorbed and grasped by the sponge suction cup 302 and put into the box. The vertical box-opening mechanism of the box-opening system 4 grabs the cardboard box at the cardboard box storage part 6 and unfolds the long side and short side of the cardboard box during the movement. The box-opening system 4 props up the two groups of long and short folding pages of the cardboard box through the box propping mechanism, facilitating the manipulator to put the single-layer materials into the cardboard box through the sponge suction cup 302. The synchronous belt type double-range mechanism of the case-sealing system 5 drives the accessory feeding suction cup to put accessories such as product manuals, upper and lower partitions, and liners into the cardboard box. The sealing mechanism of the case-sealing system 5 seals the long and short pages that are folded and aligned after folding the cardboard box and then outputs the box frame 1. The sealing mechanism of the case-sealing system 5 is a prior art and will not be elaborated here. This linear unpacking, loading, and sealing integrated machine arranges the conveying routes of the cardboard box and the materials on two parallel lines respectively. Compared with the traditional unpacking, loading, and sealing integrated machine with vertical feeding, its structure is more compact and the volume is smaller, thus facilitating the arrangement in smaller and narrower workshops. The compactly optimized material sorting system 2, box-opening system 4, and case-sealing system 5 further improve the integration degree of this integrated machine and reduce the volume. By using the sponge suction cup 302 instead of the matrix rubber suction cup group, the structure is simple and compact, saving space and cost. It can absorb materials with uneven heights. The whole sponge does no harm to the material packaging, has a high adsorption vacuum degree and a large adsorption force. By using the detection component 303, the falling-off of materials can be detected in time. Through the cooperation of multiple sprockets 515 and chains, multiple lead screws 513 are synchronously connected to achieve the purpose of synchronously rotating multiple lead screws 513. Rotating the lead screw 513 can conveniently adjust the width and spacing of the left and right opposed conveyor belts of the case-sealing system 5, so as to convey cardboard boxes of different widths. This lead screw and guide compound adjustment mechanism uses a round tube as the guide, and the lead screw is embedded to provide driving force. By selecting a suitable lead screw form, adjustment methods such as one-way and two-way centering can be achieved, greatly reducing the volume of the traditional lead screw + guide structure, having both rigidity and guidance, and being particularly suitable for small-sized integrated equipment.

The driving cylinder of the material pushing component 203 is arranged on the material sorting table 204 to reduce the occupied space.

[0037] The material boxes are linearly transported and sorted.

The short side component 704 and the long side component 706 are rotatably installed on the slide table assembly 702 in a concentric double-axis manner, thereby reducing the volume. Matrix suction cup groups are arranged on both the short side component 704 and the long side component 706.

The piston rod of the carton supporting cylinder 716 drives the rotation of one bevel gear 713 through the swing arm assembly 715. The two support plates 714 respectively drive the short pages and the long pages at the upper diagonal corners of the carton to be opened under the drive of the two bevel gears 713. The synchronous belt type double-stroke mechanism includes a fixing plate 501, a connecting piece 502, a first-stage slide table 503, a second-stage slide table 504, a synchronous belt assembly 505 and a second servo motor assembly 506. The fixing plate 501 is installed at the front of the case sealing system 5. The connecting piece 502 is fixedly installed on the fixing plate 501. The first-stage slide table 503 is slidably installed on the fixing plate 501. The second-stage slide table 504 is slidably installed on the first-stage slide table 503. The second-stage slide table 504 is used to install the accessory suction cup assembly. The accessory suction cup assembly is used to adsorb and grab accessories. The second-stage slide table 504 and the first-stage slide table 503 slide in the same direction. The synchronous belt assembly 505 is installed on the connecting piece 502. The lower belt of the synchronous belt assembly 505 is connected to the connecting piece 502. The upper belt of the synchronous belt assembly 505 is connected to the second-stage slide table 504. The second servo motor assembly 506 drives the rotation of the second-stage slide table 504. When the synchronous belt assembly 505 rotates, it drives the fixing plate 501 and the connecting piece 502 to move backward and drives the second-stage slide table 504 to move forward at the same time, realizing the doubling of the stroke of the second-stage slide table 504 and reducing the volume.

[0040] The servo motor assembly 703 drives the slide table assembly 702 to move along the slide rail assembly 701 to the carton storage section 6, so that the suction cup group on the short side component 704 adsorbs the short side of the carton. The servo motor assembly 703 drives the slide table assembly 702 to move towards the case sealing system 5. During the movement, the short side component 704 and the long side component 706 cooperate to unfold the end side and the long side of the carton, forming the carton. The short page bending component 705 bends the short page at the rear of the bottom of the carton inward. The other short pages of the carton are bent inward and sealed by the case sealing system 5 during the movement of the carton, enabling the carton to carry materials. The mechanism in the case sealing system 5 for bending and sealing the short pages at the bottom of the carton is prior art and will not be elaborated here. After the carton is unfolded by the vertical case opening mechanism, the piston rod of the case supporting cylinder 716 drives the rotation of a bevel gear 713 through the swing arm assembly 715. The two support plates 714 respectively drive the short pages and long pages at the upper diagonal corners of the carton to open outward under the drive of the two bevel gears 713, facilitating the vacuum adsorption type handling mechanism to place the single-layer material box into the carton. Adjusting the position of the support plate 712 along the long guide groove of the mounting plate 711 can be applicable to cartons of different lengths. The secondary slide table 504 drives the accessory suction cup to grab the accessories and put them into the carton. After the packing is completed, the case supporting cylinder 716 drives the two bevel gears 713 to flip through the swing arm assembly 715, so that the two support plates 714 bend the short pages inward into the carton, facilitating subsequent case sealing. Compared with the traditional long-axis series flipping case supporting mechanism and the flared mouth lifting case supporting mechanism, this case supporting mechanism is driven by a cylinder, with a compact structure, small volume, and low cost. The accessory suction cup assembly is prior art and will not be elaborated here.

[0041] As Figures 1 to 12 shown, when the linear unpacking, packing and sealing integrated machine of the present invention is working, first, the feeding belt 201 conveys the material boxes. The pushing component 203 and the fence component 205 cooperate to straighten the single-layer materials and minimize the cross-sectional area. The servo motor assembly 703 drives the slide table assembly 702 to move, so that the short side component 704 grabs the carton from the carton storage section 6, and during the movement, the short side component 704 and the long side component 706 cooperate to unfold the carton. The short page bending component 705 bends the short page at the rear of the bottom of the carton inward. The case sealing system 5 bends and seals the other short pages at the bottom of the carton. The case supporting cylinder 716 drives the two bevel gears 713 to rotate, so that the two support plates 714 open the short pages and long pages at the upper diagonal corners outward. The industrial robot 3 moves the sponge suction cup 302 through the connecting frame 301 to adsorb and grab the single-layer material and put the material into the carton. The servo motor assembly two 506 drives the synchronous belt assembly 505 to rotate, driving the secondary slide table 504 to move. The secondary slide table 504 drives the accessory suction cup to grab accessories such as product manuals, upper and lower partitions, and liners and put them into the carton. The sealing mechanism of the case sealing system 5 seals the folded and aligned long and short pages of the carton and then outputs the box frame 1.

[0042] The main functions achieved by the present invention are as follows:

[0043] 1. For this linear unpacking, loading, and sealing integrated machine, the conveying routes of the cartons and materials are arranged on two parallel lines respectively. Compared with the traditional vertical feeding unpacking, loading, and sealing integrated machine, its structure is more compact and the volume is smaller, thus facilitating the arrangement in smaller and narrower workshops.

[0044] 2. By adopting a compact and optimized material sorting system 2, carton opening system 4, and carton sealing system 5, the integration degree of this integrated machine is further improved and the volume is reduced.

[0045] 3. During material sorting, the material box is always in a constrained state, and the material sorting work is stable and reliable.
