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 technicians in this field without creative work are all 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 formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0064] Reference Figures 1 to 8 , a first direction, a second direction and an up-down direction are provided, 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 material automatic quantitative cartoning machine comprises 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, and the two ends of the material conveying line 110 are respectively set as the material conveying starting end and the material conveying end, and the direction from the material conveying starting end to the material conveying end is set as the material conveying direction, and 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 into 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, carton and other processes on 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 perform size recognition and color sorting on the material. When performing color sorting, the material is judged by color to screen out good and defective products. When performing size recognition, 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 arranged on the cartoning machine frame 001. A vacuum suction cup is provided at the output end of the material sorting device 005. The materials are sorted by the material sorting device 005. Compared with the sorting by the previous vibration screening method, the fragile materials are not easily damaged, thereby effectively ensuring the integrity of the materials.

[0072] The material automatic quantitative cartoning machine also includes a large-size conveying line 002, a large-size collecting basket 003 and a defective product collecting basket 004.

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

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

[0075] When the visual recognition device 120 detects large-sized materials, the coordinates of the large-sized materials are recorded, and then the large-sized materials are picked up and transported to the nearest large-sized conveyor line 002 through the material sorting equipment 005. 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, and 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 with 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 reweighting conveyor line 730, a preliminary material placement device 810, a reweighting transport device 820, and a reweighting control module.

[0080] The weight-adding control module is integrated into the control system of the cartoning machine. In other embodiments, the weight-adding control module can also be set 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-weighting 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-weighting 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 butted against 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 driving 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] The weighing conveyor line 720 is a transmission weighing platform, which is composed of a belt conveyor and a first weighing module (the first weighing module is not shown in the figure). The first weighing module is set as a weighing sensor and is arranged at the bottom of the belt conveyor. When the container is transported into the weighing conveyor line 720 by other components of the cartoning machine, the first weighing module automatically returns to zero to avoid the weight of the container causing an error in the total weight of the boxed material.

[0085] The starting end of the reweighting conveyor line 730 is butted against the end of the weighing conveyor line 720. After the container on the weighing conveyor line 720 is loaded to a set weight, the weighing conveyor line 720 conveys the container to the reweighting conveyor line 730. The reweighting conveyor line 730 is a conventional belt conveyor. The reweighting conveyor line 730 and the weighing conveyor line 720 are each equipped with a driving motor so that the reweighting conveyor line 730 and the weighing conveyor line 720 can operate independently.

[0086] By setting up the 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 operation efficiency of the cartoning machine.

[0087] Specifically, in this embodiment, both sides of the empty container feeding conveyor line 710, both sides of the weighing conveyor line 720, and both sides of the weight-adding conveyor line 730 are provided with limit baffles 910, which can limit the container, thereby preventing the container from falling off the conveyor line and other undesirable situations. Specifically, in this embodiment, the end of the limit baffle 910 is provided with a guide plate 920, which is inclined and can guide the container so that the container can smoothly transition between two adjacent conveyor lines.

[0088] The preparation material placement device 810 is arranged beside the weight replenishing conveying line 730 (the preparation material placement device 810 and the weight replenishing conveying line 730 are arranged in sequence in the second direction), and the number of the preparation material placement devices 810 is set to multiple, and the multiple preparation material placement devices 810 are arranged at equal intervals along the first direction. The preparation material placement device 810 is provided with a second weighing module (the second weighing module is not shown in the figure). The sorting device of the cartoning machine moves a single material to the preparation material placement device 810, and the preparation material placement device 810 supports the material and weighs the single material.

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

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

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

[0093] The first re-weight driving component 822 is fixedly installed on the cartoning machine frame 001. The first re-weight driving component 822 is a belt-driven linear module. The driving direction of the first re-weight driving component 822 is set parallel to the first direction. The first re-weight driving component 822 is used to drive the re-weight 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 weight-adding driving member 823 is fixedly mounted on the weight-adding connecting plate, and is configured as a linear cylinder. The driving direction of the second weight-adding driving member 823 is parallel to the up-down direction, and is used to drive the weight-adding suction cup structure 821 to move in the up-down direction.

[0096] The third weight-adding driving member 824 includes two linear cylinders, which are respectively set as a first linear cylinder 825 and a second linear cylinder 826. The first linear cylinder 825 and the second linear cylinder 826 are arranged in the front-to-back direction. The first linear cylinder 825 is fixedly installed at the output end of the second weight-adding driving member 823, and the second linear cylinder 826 is fixedly installed at the output end of the first linear cylinder 825. The driving directions of the first linear cylinder 825 and the second linear cylinder 826 are the same, both parallel to the second direction. The third weight-adding driving member 824 is used to drive the weight-adding suction cup structure 821 to move along the second direction, so that the weight-adding suction cup structure 821 moves back and forth between the preparation material placement device 810 and the weight-adding conveying line 730. By setting the third weight-adding driving member 824 as a structure including two linear cylinders, the space occupied by the third weight-adding driving member 824 in the second direction when it is folded can be reduced, so that other components of the cartoning machine can have a larger range of movement.

[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 re-weighting transport devices 820 is set to two, so that the material quantitative weighing component can simultaneously transport two materials to the container of the re-weighting conveying line 730. Compared with the use of a single re-weighting transport device 820, the two re-weighting transport devices 820 do not need to move back and forth repeatedly, thereby reducing the number of movement steps of the re-weighting transport 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, then calculates the average weight of the extracted materials, sets the average weight as W, and sets a G value, G is one to two times of W, and the specific ratio of G to W is set based on experience; for small, medium and large specifications of materials, the average weight of each specification is calculated separately;

[0101] Step S002, transporting a plurality of materials to a plurality of prepared material placement devices 810, so that each prepared material placement device 810 has 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 container for the empty container feeding conveyor line 710;

[0103] Step S004: The material is picked up and placed in a container on the weighing conveyor line 720. The first weighing module starts to accumulate the weight. Let the target weight be T0, and the target weight T0 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 supplementary weighing conveyor line 730.

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

[0106] Step S007: The supplementary weighing handling device 820 transports the picked-up materials into the container on the supplementary weighing conveyor line 730 to complete the supplementary weighing step.

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

[0108] The number of weighing conveyor components is set to four, and the four weighing conveyor components are symmetrically arranged in two groups on both sides of the material conveyor line 110. The two weighing conveyor components on the same side of the material conveyor 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 box-packing machine frame 001. The out-box conveyor line 400 is fixedly arranged relative to the box-packing machine frame 001. The out-box conveyor line 400 is used to transport the packaging box containing the material so that the packaging box containing 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 conveyor are arranged in the up-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 conveyor. Since the length direction of the box-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 box-packing machine, and multiple box-packing machines can use the same out-box conveyor line 400 to transport the packaging boxes containing the material, thereby improving the utilization rate of the out-box conveyor line 400.

The box return conveyor line 230 drives the packaging box to move in a direction close to the box conveyor line 400. The box 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-position input 242 to the second low-position output 241. After the packaging box is transported to the second low-position output 241, the second lifting conveyor device 240 transports the packaging box to the box conveyor line 400.

[0142] The packaging box in the second cartoning assembly 300 will be transported by the second cartoning conveyor line 310 and move toward the direction close to the box-out conveyor line 400. During the transportation of the packaging box by the second cartoning conveyor line 310, the material is moved into the packaging box by the material sorting device 005, thereby realizing the boxing of the material. After the packaging box is transported to the third lifting conveyor device 320, the third lifting conveyor device 320 drives the packaging box to move upward. When the packaging box moves to the third high-position output 322, the third lifting conveyor device 320 will transport the packaging box to the box-out conveyor line 400. By providing the first cartoning assembly 200 and the second cartoning assembly 300, the working efficiency of the cartoning machine can be improved.

[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 conveyor 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 conventional box-outlet conveyor line 400 and the material conveyor line 110 being arranged at both ends of the cartoning machine, thereby reducing the factory space occupied by the cartoning machine.
