Description

Technical Field

[0001] The present invention relates to the technical field of cartoning equipment, in particular to an automatic quantitative material cartoning machine and a quantitative material weighing method. Background Art

[0002] On the food packaging line, some materials need to go through sorting and weighing processes before packaging. Some materials are sorted according to different size ranges, and some are sorted according to good and bad products (usually determined by whether the color is normal). After sorting, they are placed in containers according to a certain weight for packaging.

[0003] Currently, there are devices on the market that can independently perform one of the above functions. For example, if size sorting is required, there are size sorting machines. The principle is to use screens or gaps of different sizes to allow materials of different sizes to pass through the screen holes or gaps for sorting; if color sorting is required, there are color sorters. Color sensors are used to determine whether the color of the material is normal and sort out good and bad products; combination scales are used for weighing; and conventional material boxing equipment is used for material boxing.

[0004] Existing equipment can only realize one of the functions, and there are equipment that integrates multiple functions mentioned above. Different equipment needs to be connected with lifting mechanisms, conveying mechanisms and other mechanisms to realize the flow of materials between different equipment, which requires a large factory space.

DETAILED DESCRIPTION

[0063] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interactively without conflicting with each other.

[0064] Reference Figures 1 to 8 , there are a first direction, a second direction and an up and down direction, the first direction and the second direction are perpendicular to each other, and the first direction and the second direction are parallel to the horizontal plane.

[0065] The automatic quantitative material cartoning machine includes a cartoning machine frame 001, a material conveying line 110, a visual recognition device 120, a weighing and conveying component, a material sorting device 005 and a box-out conveying line 400.

[0066] The material conveying line 110 is fixedly arranged on the cartoning machine frame 001. The two ends of the material conveying line 110 are respectively set as the material conveying starting end and the material conveying end. The direction from the material conveying starting end to the material conveying end is set as the material conveying direction. The material conveying direction is parallel to and in the same direction as the first direction.

[0067] The material conveying line 110 is a conventional belt conveyor, which is equipped with a driving device, a transmission structure, a transmission roller, a belt and other structures.

[0068] The material conveying line 110 penetrates the cartoning machine frame 001 from the outside of the cartoning machine frame 001. The material conveying line 110 is used to convey the materials to the cartoning machine so that other components of the cartoning machine can sort, weigh and carton the materials.

[0069] The material conveying line 110 is provided with two sorting stations arranged along a first direction.

[0070] The visual recognition device 120 is fixedly connected to the cartoning machine frame 001. The visual recognition device 120 is arranged above the material conveying line 110. The visual recognition device 120 is used to identify the size and color of the material. When performing color sorting, the material is judged by color to screen out good and defective products. When performing size identification, the visual recognition device 120 coordinates the material and calculates the length, width, diameter, area and other data of the material through the pixel points of the material imaging as the basis for size sorting.

[0071] The material sorting device 005 is fixedly installed on the cartoning machine frame 001. The output end of the material sorting device 005 is provided with a vacuum suction cup. The material is sorted by the material sorting device 005. Compared with the previous vibration screening method for sorting, fragile materials are not easily damaged, thereby effectively ensuring the integrity of the materials.

[0072] The automatic quantitative cartoning machine for materials also includes a large-size conveyor line 002, a large-size collection basket 003 and a defective product collection basket 004.

[0073] The large-sized collection basket 003 is placed on the cartoning machine frame 001.

[0074] Large-format conveyor line 002 is fixedly mounted on cartoning machine frame 001 and is located at an end away from the starting end of material conveyor line 110. Two large-format conveyor lines 002 are provided, arranged along the second direction. The starting ends of the two large-format conveyor lines 002 are respectively located corresponding to the two material sorting devices 005, and the ends of the two large-format conveyor lines 002 are both located above the large-format collection basket 003.

[0075] When the visual recognition device 120 detects large-sized materials, it records the coordinates of the large-sized materials, and then uses the material sorting equipment 005 to pick up the large-sized materials and transport them to the nearest large-sized conveyor line 002. Then, the large-sized conveyor line 002 moves the large-sized materials to the top of the large-sized collection basket 003. After the large-sized materials leave the large-sized conveyor line 002, they fall into the large-sized collection basket 003 due to the action of gravity.

[0076] The defective product collection basket 004 is placed on the cartoning machine frame 001 , and the defective product collection basket 004 is arranged below the end of the material conveying line 110 .

[0077] When the visual recognition device 120 detects a defective product, the coordinates of the defective product are recorded. The material sorting equipment 005 does not operate on the defective product. The material conveying line 110 conveys the defective product to the top of the defective product collection basket 004. After the defective product leaves the material conveying line 110, it falls into the defective product collection basket 004 due to the action of gravity.

[0078] The weighing and conveying assembly comprises a weighing and conveying structure and a container conveying structure. The starting end of the container conveying structure is butted against the end of the weighing and conveying structure.

[0079] Specifically, the weighing and conveying structure includes: an empty container feeding conveyor line 710, a weighing conveyor line 720, a reweight conveyor line 730, a preliminary material placement device 810, a reweight transport device 820, and a reweight control module.

[0080] The re-weighting control module is integrated into the control system of the cartoning machine. In other embodiments, the re-weighting control module can also be provided as a separate control module.

[0081] The conveying directions of the empty container feeding conveyor line 710, the weighing conveyor line 720, and the re-weighing conveyor line 730 are all parallel to the first direction. The empty container feeding conveyor line 710, the weighing conveyor line 720, and the re-weighing conveyor line 730 are sequentially arranged along the first direction.

[0082] The empty container feeding conveyor line 710 is configured as a conventional belt conveyor.

[0083] The starting end of the weighing conveyor line 720 is connected to the end of the empty container feeding conveyor line 710, and the empty container feeding conveyor line 710 conveys empty containers to the weighing conveyor line 720. The weighing conveyor line 720 and the empty container feeding conveyor line 710 are each equipped with a drive motor, so that the weighing conveyor line 720 and the empty container feeding conveyor line 710 can operate independently, thereby ensuring that each step of quantitative weighing is carried out in an orderly manner.

[0084] Weighing conveyor line 720 is a transport-type weighing platform consisting of a belt conveyor and a first weighing module (not shown). The first weighing module is a load cell and is located at the bottom of the belt conveyor. When a container is transported onto weighing conveyor line 720 by other components of the cartoning machine, the first weighing module automatically resets to zero to prevent the container's weight from influencing the total weight of the boxed material.

[0085] The starting end of the reweight conveyor line 730 is connected to the end of the weighing conveyor line 720. After the containers on the weighing conveyor line 720 are loaded to the set weight, the weighing conveyor line 720 conveys the containers to the reweight conveyor line 730. The reweight conveyor line 730 is a conventional belt conveyor. The reweight conveyor line 730 and the weighing conveyor line 720 are each equipped with a drive motor to enable the reweight conveyor line 730 and the weighing conveyor line 720 to operate independently.

[0086] By setting up an empty container feeding conveyor line 710, during the process of loading containers on the weighing conveyor line 720, the empty container feeding conveyor line 710 replenishes containers and waits for the loading of containers on the weighing conveyor line 720 to be completed. After the loading of containers on the weighing conveyor line 720 is completed, the weighing conveyor line 720 transports the containers filled with materials to the replenishing conveyor line 730, and then the empty container feeding conveyor line 710 immediately transports the empty containers to the weighing conveyor line 720, so that the weighing conveyor line 720 can quickly carry out the next loading, thereby ensuring the operating efficiency of the cartoning machine.

[0087] Specifically, in this embodiment, limit baffles 910 are provided on both sides of the empty container feeding conveyor line 710, both sides of the weighing conveyor line 720, and both sides of the reweight conveyor line 730. The limit baffles 910 can limit the position of the containers, thereby preventing the containers from falling off the conveyor lines and other undesirable situations. Specifically, in this embodiment, guide plates 920 are provided at the ends of the limit baffles 910. The guide plates 920 are arranged at an angle and can guide the containers so that the containers can smoothly transition between two adjacent conveyor lines.

[0088] The preparatory material placement device 810 is located adjacent to the re-weight conveyor line 730 (the preparatory material placement device 810 and the re-weight conveyor line 730 are arranged sequentially in the second direction). Multiple preparatory material placement devices 810 are provided, and are spaced evenly apart along the first direction. Each preparatory material placement device 810 is equipped with a second weighing module (not shown). The cartoning machine's sorting device moves individual items onto the preparatory material placement device 810, which supports and weighs the individual items.

[0089] Specifically, in this embodiment, the number of the preparation material placement devices 810 is set to six, and the six preparation material placement devices 810 are arranged along the first direction. When the material is placed in the preparation material placement device 810, the weight of the corresponding single material can be known. The weight replenishment control module performs a single or two weight combinations on the weight of the materials in the preparation material placement device 810. The number of combinations is That is, 21 types. The number of the preparation material placement devices 810 can be increased according to demand, and the corresponding number of weight combinations will also increase.

[0090] The re-weight transport device 820 is used to transport the materials from the prepared material placement device 810 to the container of the re-weight conveying line 730 to achieve re-weighting.

[0091] The supplementary weight transport device 820 includes: a supplementary weight suction cup structure 821 , a first supplementary weight driving component 822 , a second supplementary weight driving component 823 , and a third supplementary weight driving component 824 .

[0092] The weight-replenishing suction cup structure 821 is configured as a vacuum suction cup.

[0093] The first weight-replenishing driving component 822 is fixedly installed on the cartoning machine frame 001. The first weight-replenishing driving component 822 is a belt-driven linear module. The driving direction of the first weight-replenishing driving component 822 is set parallel to the first direction. The first weight-replenishing driving component 822 is used to drive the weight-replenishing suction cup structure 821 to move along the first direction.

[0094] A supplementary weight connecting plate is fixed to the output end of the first supplementary weight driving member 822 .

[0095] The second auxiliary weight driving member 823 is fixedly mounted on the auxiliary weight connecting plate and is configured as a linear cylinder. The driving direction of the second auxiliary weight driving member 823 is parallel to the vertical direction and is used to drive the auxiliary weight suction cup structure 821 to move in the vertical direction.

[0096] The third re-weight driver 824 comprises two linear cylinders, designated as a first linear cylinder 825 and a second linear cylinder 826, respectively. The first linear cylinder 825 and the second linear cylinder 826 are arranged in a front-to-back direction. The first linear cylinder 825 is fixedly mounted to the output end of the second re-weight driver 823, and the second linear cylinder 826 is fixedly mounted to the output end of the first linear cylinder 825. The first and second linear cylinders 825 and 826 operate in the same direction, parallel to the second direction. The third re-weight driver 824 is used to drive the re-weight suction cup structure 821 in the second direction, thereby moving the re-weight suction cup structure 821 back and forth between the preparatory material placement device 810 and the re-weight conveyor line 730. By configuring the third re-weight driver 824 as a two-cylinder structure, the space occupied by the third re-weight driver 824 in the second direction when retracted is reduced, thereby allowing other components of the cartoning machine to have a greater range of motion.

[0097] Specifically, in this embodiment, the number of the supplementary weight transporting devices 820 is set to two, and the two supplementary weight transporting devices 820 share the same first supplementary weight driving component 822, that is, the second supplementary weight driving components 823 of the two supplementary weight transporting devices 820 are fixedly installed on the same supplementary weight connecting plate.

[0098] The number of the re-weighing conveying devices 820 is set to two, so that the material quantitative weighing component can simultaneously transport two materials to the container of the re-weighing conveying line 730. Compared with using a single re-weighing conveying device 820, the two re-weighing conveying devices 820 do not require the re-weighing conveying device 820 to move back and forth repeatedly, thereby reducing the number of movement steps of the re-weighing conveying device 820 and improving the working efficiency of the material quantitative weighing component.

[0099] Quantitative weighing methods for materials, including:

[0100] Step S001: The staff randomly selects 10-20 materials of the same specification and weighs the selected materials. The average weight of the extracted materials is then calculated, and the average weight is set as W. A value G is set, which is one to two times W. The specific ratio of G to W is set based on experience. For small, medium, and large specifications, the average weight of each specification is calculated separately.

[0101] Step S002: transport multiple materials to multiple preparatory material placement devices 810 so that each preparatory material placement device 810 contains a single material;

[0102] Step S003: The container is conveyed to the weighing conveyor line 720 by the empty container feeding conveyor line 710, the first weighing module is reset to zero, and then other components of the cartoning machine replenish the empty container feeding conveyor line 710 with containers;

[0103] Step S004: The material is picked up and placed in a container on the weighing conveyor line 720. The first weighing module starts accumulating the weight. Let the target weight be T0, which is set according to requirements. The accumulated weight is T1, and ΔT = T0 - T1.

[0104] Step S005: When ΔT < G, the weighing conveyor line 720 transports the container with the material to the weight - supplement conveyor line 730.

[0105] Step S006: The weight - supplement control module combines the weights of the materials in the preliminary material placement device 810 individually or in groups of two. The weight - supplement control module selects the weight combination closest to ΔT from multiple combinations and controls the weight - supplement handling device 820 to pick up the materials of the corresponding weight combination.

[0106] Step S007: The weight - supplement handling device 820 transports the picked - up materials into the container on the weight - supplement conveyor line 730, completing the weight - supplement step.

[0107] Subsequently, steps S002 to S007 are repeatedly executed.

[0108] The number of weighing and conveying components is set to four. The four weighing and conveying components are symmetrically arranged in pairs on both sides of the material conveying line 110. The two weighing and conveying components on the same side of the material conveying line 110 are respectively set as the second component 140 and the first component 130. In the first direction, the first component 130 is arranged in front of the second component 140.

[0109] The out - box conveyor line 400 is arranged outside the packing machine frame 001. The out - box conveyor line 400 is fixedly arranged relative to the packing machine frame 001 and is used to convey the packing box with the material so that the packing box with the material moves to the next process or other places to wait for subsequent processing steps to be executed.

[0110] The out - box conveyor line 400 is also set as a conventional belt conveyor. The out - box conveyor line 400 and the starting end of the material conveying are arranged in the up - and - down direction, and the conveying direction of the out - box conveyor line 400 is perpendicular to the material conveying direction. Specifically, in this embodiment, the out - box conveyor line 400 is arranged above the starting end of the material conveying. Since the length direction of the packing machine is parallel to the material conveying direction, by setting the conveying direction of the out - box conveyor line 400 to be perpendicular to the material conveying direction, the out - box conveyor line 400 extends along the width direction of the packing machine, and multiple packing machines can use the same out - box conveyor line 400 to transport the packing boxes with the material, thus improving the utilization rate of the out - box conveyor line 400.

[0111] The container conveying structure of the first assembly 130 is configured as a first cartoning assembly 200 . The first cartoning assembly 200 includes a first lifting conveyor 220 , a box-outgoing return conveyor line 230 , and a second lifting conveyor 240 .

[0112] Baffles 611 for limiting the position of packaging boxes are provided on both sides of the first cartoning conveyor line 210 .

The lifting linear drive device 620 drives the lifting conveyor belt 610 to move in the up and down directions to lift the packaging box on the first lifting conveyor device 220 from the first low-position input 221 to the first high-position output 222. When the packaging box is lifted to the first high-position output 222, the lifting conveyor belt 610 of the first lifting conveyor device 220 works to transport the packaging box containing the material to one side, so that the packaging box containing the material is moved to the next conveying structure.

[0115] Baffles 611 for limiting the position of the packaging boxes are provided on both sides of the lifting conveyor belt 610 .

[0116] The outgoing return conveyor 230 is located at the top of the cartoner frame 001. Its starting point is connected to the first high-level output 222.

[0119] The second lifting conveyor 240 is provided with a second low-level output 241 and a second high-level input 242. The second low-level output 241 is located below the second high-level input 242, and the second high-level input 242 is connected to the end of the box return conveyor line 230, and the second low-level output 241 is connected to the box conveyor line 400.

[0120] The container conveying structure of the second assembly 140 includes a third lifting and conveying device 320 .

[0121] The third lifting conveyor device 320 is arranged between the second box loading conveyor line 310 and the box unloading conveyor line 400. The specific structure of the third lifting conveyor device 320 is the same as the specific structure of the first lifting conveyor device 220 and the second lifting conveyor device 240. The specific structure of the third lifting conveyor device 320 will not be repeated here.

[0122] The third lifting conveyor 320 is provided with a third high-level output 322 and a third low-level input 321.

[0123] By setting the first component 130 and the second component 140, the first component 130 and the second component 140 are respectively set corresponding to the two material sorting devices 005, that is, double-station sorting and loading is realized, thereby improving the working efficiency of the cartoning machine.

[0124] The number of packaging box assemblies 500 is set to two, and the two packaging box assemblies 500 are respectively arranged on both sides of the material conveying line 110. The number of packaging box assemblies 500 is set to two, and the two packaging box assemblies 500 can be used to store and provide packaging boxes of different specifications to meet different packaging needs.

[0125] Specifically, the packaging box assembly 500 includes a packaging box placement device 510 , a box delivery structure 520 , and a box removal device 530 .

[0126] The packaging box placement device 510 is set at one end of the cartoning machine away from the box output conveyor line 400. Setting the packaging box placement device 510 at a position away from the box output conveyor line 400 can make it more convenient for staff to replenish packaging boxes to the packaging box placement device 510, avoiding obstruction of the box output conveyor line 400 to the replenishment of packaging boxes.

[0127] Specifically, the packaging box placement device 510 includes a plurality of side enclosure structures 511. In this embodiment, there are four side enclosure structures 511 arranged in a rectangular shape. The four side enclosure structures 511 enclose a packaging box placement space, which is a straight channel-like structure with a rectangular cross-section. The lower end of the packaging box placement space is provided as a packaging box removal area.

[0128] A limiting protrusion 512 is provided at the lower end of the side enclosure structure 511. The limiting protrusion 512 is used to hook the edge of the packaging box to limit the packaging box, thereby preventing the packaging box from accidentally falling due to its own gravity.

[0129] This solution centrally arranges the packaging box placement device 510, the large-size conveyor line 002, the large-size collection basket 003 and the defective product collection basket 004 at the same end of the cartoning machine, which can make it more convenient for the staff to take out large-size materials, take out defective products and place packaging boxes. Compared with the scattered arrangement of the packaging box placement device 510, the large-size conveyor line 002, the large-size collection basket 003 and the defective product collection basket 004, the work efficiency of the staff can be improved.

[0130] In this embodiment, two adjacent side enclosure structures 511 are configured as fixed enclosures 513 , and the other two side enclosure structures 511 are configured as adjustable enclosures 514 .

[0131] The fixed enclosure 513 is fixedly connected to the cartoning machine frame 001 via screws. The adjustable enclosure 514 is slidably connected to the cartoning machine frame 001. The adjustable enclosure 514 can be moved closer to or further away from the inner side of the packaging box placement space, thereby adjusting the size of the packaging box placement space. Specifically, an adjusting bolt is provided between the adjustable enclosure 514 and the cartoning machine frame 001. The end of the adjusting bolt is rotatably connected to the adjusting enclosure 514, which is threadedly connected to the cartoning machine frame 001. A rotating head is fixed to the end of the adjusting bolt away from the adjusting enclosure 514. The operator can manually twist the rotating head to adjust the distance between the fixed enclosure 513 and the adjusting enclosure 514.

[0132] The box conveying structure 520 is fixedly mounted on the cartoning machine frame 001 and includes a second box conveying end and a first box conveying end. The first box conveying end is positioned below the package box placement device 510, and the second box conveying end interfaces with the empty container feed conveyor line 710 of the first assembly 130 and the empty container feed conveyor line 710 of the second assembly 140. The box conveying structure 520 is used to convey packages from the first box conveying end to the second box conveying end. The box conveying structure 520 can selectively convey packages to either the empty container feed conveyor line 710 of the first assembly 130 or the empty container feed conveyor line 710 of the first assembly 130 of the second assembly 140, thereby achieving diversion of packages.

[0133] Specifically, in this embodiment, the box conveying structure 520 includes a main box conveying line 521 and a box lifting conveying device 522. Both sides of the main box conveying line 521 and the box lifting conveying device 522 are provided with baffles 611 for limiting the packaging boxes.

[0134] The main box conveying line 521 is configured as a conventional belt conveyor. In this embodiment, the conveying direction of the main box conveying line 521 is opposite to the material conveying direction, and the first box conveying end is the starting end of the main box conveying line 521 .

[0135] Specifically, in this embodiment, the main box feeding conveyor line 521 includes two box feeding conveyor belts, which are parallel to each other and arranged horizontally in parallel. The box feeding conveyor belts are conventional belt conveyors, and the two box feeding conveyor belts move synchronously.

[0136] The box-feeding lifting conveyor 522 includes a belt conveyor and a lifting drive mechanism. The lifting drive mechanism drives the belt conveyor up and down, and the belt conveyor drives the packaging boxes in a direction that is in the same direction as the material conveying direction or in a direction opposite to the material conveying direction, so that the packaging boxes enter the first assembly 130 or the second assembly 140, thereby achieving packaging box diversion and meeting the requirements of multi-station loading. The second box-feeding end is configured as the output end of the box-feeding lifting conveyor 522.

[0137] Baffles 611 for limiting the position of packaging boxes are provided on both sides of the main box conveying line 521 and the box lifting and conveying device 522.

[0138] The box removal device 530 is located between the two box feeding conveyors and includes a suction cup structure 531 and a suction cup driver 532. The suction cup driver 532 is fixedly mounted to the cartoning machine frame 001. In this embodiment, the suction cup driver 532 is configured as a linear cylinder. The suction cup structure 531 is fixedly mounted at the output end of the suction cup driver 532. The suction cup driver 532 drives the suction cup structure 531 up and down, moving it closer to or further away from the box removal area.

[0139] When it is necessary to take out the packaging box, the suction cup driving component 532 drives the suction cup structure 531 to approach the packaging box taking-out position, and the suction cup structure 531 absorbs the packaging box at the bottom of the packaging box taking-out position, and then the suction cup driving component 532 drives the suction cup structure 531 to move away from the packaging box taking-out position. When the height of the suction cup structure 531 is lower than the conveying plane of the box feeding conveyor belt, the packaging box is blocked by the box feeding conveyor belt and cannot continue to be transported downward, so that the suction cup structure 531 is separated from the packaging box, and then the box feeding conveyor belt can transport the packaging box.

[0140] The implementation process of this solution is as follows: the box removal device 530 first removes the box from the box placement device 510, and then the main box delivery conveyor line 521 transports the box to the box delivery elevator conveyor 522. After the box moves to the box delivery elevator conveyor 522, the box delivery elevator conveyor 522 drives the box to rise and then drives the box into the first cartoning assembly 200 or the second cartoning assembly 300.

[0141] The packaging box in the first cartoning assembly 200 will be transported by the first cartoning conveyor line 210 and move in a direction away from the box-out conveyor line 400. During the transportation of the packaging box by the first cartoning conveyor line 210, the material is moved into the packaging box by other components, thereby realizing the boxing of the material. After the packaging box is transported to the first lifting conveyor device 220, the first lifting conveyor device 220 drives the packaging box to move upward. After the packaging box moves to the first high-level output 222, the first lifting conveyor device 220 drives the packaging box to enter the box-out return conveyor line 230. The box-out return conveyor line 230 drives the packaging box to move in a direction close to the box-out conveyor line 400. The box-out return conveyor line 230 finally transports the packaging box to the second lifting conveyor device 240. Subsequently, the packaging box is transported by the second lifting conveyor device 240 and moves from the second high-level input 242 to the second low-level output 241. After the packaging box is conveyed to the second low-level output 241, the second lifting conveyor device 240 conveys the packaging box to the box-out conveyor line 400.

[0142] The packages in the second cartoning assembly 300 are transported by the second cartoning conveyor line 310 toward the outgoing conveyor line 400. While the packages are being transported by the second cartoning conveyor line 310, the materials are moved into the packages by the material sorting device 005, thereby completing the process of boxing the packages. Once the packages are transported to the third lifting conveyor 320, they are driven upward. Once the packages reach the third high-position output 322, the third lifting conveyor 320 delivers the packages to the outgoing conveyor line 400. The provision of the first cartoning assembly 200 and the second cartoning assembly 300 improves the efficiency of the cartoning machine.

[0143] By arranging components such as the box-outlet return conveyor line 230, the first lifting conveyor device 220, and the second lifting conveyor device 240, the box-outlet conveyor line 400 and the material conveying line 110 can be arranged at the same end, which can make the overall structure of the cartoning machine more compact and avoid the use of the previous method of arranging the box-outlet conveyor line 400 and the material conveying line 110 at both ends of the cartoning machine, thereby reducing the factory space occupied by the cartoning machine.

[0144] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
