[0064] REFERENCE Figures 1 to 8 , there are a first direction, a second direction and an up-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 material automatic quantitative boxing machine comprises a boxing machine rack 001, a material conveying line 110, a visual identification device 120, a weighing conveying assembly, a material sorting device 005 and an out-box conveying line 400.

[0066] The material conveying line 110 is fixedly arranged on the boxing machine rack 001, and two ends of the material conveying line 110 are respectively provided as a material conveying starting end and a material conveying ending end.

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

[0068] The material conveying line 110 penetrates into the boxing machine rack 001 from the outside of the boxing machine rack 001, and is used for conveying materials to the boxing machine, so that other components of the boxing machine can sort, weigh and box the materials.

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

[0070] The visual identification device 120 is fixedly connected with the boxing machine rack 001, and is arranged above the material conveying line 110.

[0071] The material sorting device 005 is fixedly arranged on the boxing machine rack 001, and an output end of the material sorting device 005 is provided with a vacuum chuck.

[0072] The material automatic quantitative boxing machine further comprises a large-specification conveying line 002, a large-specification collecting basket 003 and a defective product collecting basket 004.

[0073] The large-specification collecting basket 003 is placed on the boxing machine rack 001.

[0074] The large-specification conveying line 002 is fixedly arranged on the cartoning machine rack 001, and is arranged at an end away from the starting end of the material conveying line 110. The number of the large-specification conveying line 002 is two, and the two large-specification conveying lines 002 are arranged along the second direction. The starting ends of the two large-specification conveying lines 002 are correspondingly arranged with the two material sorting devices 005, and the ending ends of the two large-specification conveying lines 002 are arranged above the large-specification collection basket 003.

[0075] When the visual recognition device 120 detects the large-specification material, the coordinates of the large-specification material are recorded. Then, the large-specification material is picked up by the material sorting device 005 and carried to the nearest large-specification conveying line 002. Then, the large-specification conveying line 002 moves the large-specification material above the large-specification collection basket 003. After the large-specification material is separated from the large-specification conveying line 002, it falls into the large-specification collection basket 003 due to gravity.

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

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

[0078] The weighing conveying assembly includes a weighing conveying structure and a container conveying structure. The starting end of the container conveying structure is connected to the ending end of the weighing conveying structure.

[0079] Specifically, the weighing conveying structure includes an empty container feeding conveying line 710, a weighing conveying line 720, a counterweight conveying line 730, a pre-preparation material placing device 810, a counterweight carrying device 820, and a counterweight control module.

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

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

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

[0083] The starting end of the weighing conveying line 720 is connected with the ending end of the empty container feeding conveying line 710, and the empty container feeding conveying line 710 feeds the empty containers to the weighing conveying line 720. The weighing conveying line 720 and the empty container feeding conveying line 710 are respectively provided with driving motors, so that the weighing conveying line 720 and the empty container feeding conveying line 710 can be independently operated, thereby ensuring the orderly performance of each step of the quantitative weighing.

[0084] The weighing conveying line 720 is a transmission type weighing platform, which is composed of a belt conveyor and a first weighing module (not shown in the figure). The first weighing module is provided with a weighing sensor and is arranged at the bottom of the belt conveyor. When the container is transmitted into the weighing conveying line 720 by other components of the box filling machine, the first weighing module is automatically zeroed to avoid the weight of the container from bringing errors to the total weight of the filled material.

[0085] The starting end of the counterweight conveying line 730 is connected with the ending end of the weighing conveying line 720, and the container on the weighing conveying line 720 is filled to the set weight, and then the weighing conveying line 720 feeds the container to the counterweight conveying line 730. The counterweight conveying line 730 is a conventional belt conveyor, and the counterweight conveying line 730 and the weighing conveying line 720 are respectively provided with driving motors, so that the counterweight conveying line 730 and the weighing conveying line 720 can be independently operated.

[0086] By arranging the empty container feeding conveying line 710, during the filling of the container on the weighing conveying line 720, the empty container feeding conveying line 710 supplements the containers and waits for the completion of the filling of the container on the weighing conveying line 720. After the completion of the filling of the container on the weighing conveying line 720, the weighing conveying line 720 feeds the container filled with the material to the counterweight conveying line 730, and then the empty container feeding conveying line 710 immediately feeds the empty container to the weighing conveying line 720, so that the weighing conveying line 720 can quickly perform the next filling, thereby ensuring the operation efficiency of the box filling machine.

[0087] Specifically, in the embodiment, limit stop plates 910 are arranged on both sides of the empty container feeding conveying line 710, both sides of the weighing conveying line 720, and both sides of the counterweight conveying line 730. The limit stop plates 910 can limit the containers, thereby avoiding the occurrence of adverse conditions such as the falling of the containers from the conveying lines. Specifically, in the embodiment, the end of the limit stop plate 910 is provided with a guide plate 920, and the guide plate 920 is arranged obliquely. The guide plate 920 can guide the containers, so that the containers can smoothly transition between two adjacent conveying lines.

[0088] The pre-preparation material placing device 810 is arranged beside the counterweight conveying line 730 (the pre-preparation material placing device 810 and the counterweight conveying line 730 are arranged in sequence in the second direction), the number of the pre-preparation material placing device 810 is set to be multiple, and the multiple pre-preparation material placing devices 810 are arranged equidistantly in the first direction. The pre-preparation material placing device 810 is provided with a second weighing module (not shown in the figure). The sorting device of the boxing machine moves a single material to the pre-preparation material placing device 810, and the pre-preparation material placing device 810 supports the material and weighs the single material.

[0089] Specifically, in the embodiment, the number of the pre-preparation material placing device 810 is set to six, and the six pre-preparation material placing devices 810 are arranged in the first direction. When the material is placed in the pre-preparation material placing device 810, the weight of the corresponding single material can be known, and the counterweight control module weighs the material in the pre-preparation material placing device 810 individually or in combination of two, and the number of combinations is i.e. 21, and the number of the pre-preparation material placing device 810 can be increased according to the demand, and the corresponding number of weight combinations will also increase.

[0090] The counterweight carrying device 820 is used to carry the material in the pre-preparation material placing device 810 to the container of the counterweight conveying line 730 to realize counterweight.

[0091] The counterweight carrying device 820 comprises a counterweight suction cup structure 821, a first counterweight driving member 822, a second counterweight driving member 823, and a third counterweight driving member 824.

[0092] The counterweight suction cup structure 821 is set as a vacuum suction cup.

[0093] The first counterweight driving member 822 is fixedly installed on the boxing machine rack 001, the first counterweight driving member 822 is a belt-driven linear module, the driving direction of the first counterweight driving member 822 is parallel to the first direction, and the first counterweight driving member 822 is used to drive the counterweight suction cup structure 821 to move in the first direction.

[0094] The output end of the first counterweight driving member 822 is fixed with a counterweight connecting plate.

[0095] The second counterweight driving member 823 is fixedly installed on the counterweight connecting plate, and the second counterweight driving member 823 is set as a linear cylinder. The driving direction of the second counterweight driving member 823 is parallel to the up-down direction, and the second counterweight driving member 823 is used to drive the counterweight suction cup structure 821 to move in the up-down direction.

[0096] The third counterweight driving member 824 comprises two linear cylinders, which are respectively a first linear cylinder 825 and a second linear cylinder 826, and the first linear cylinder 825 and the second linear cylinder 826 are arranged along the front-rear direction, the first linear cylinder 825 is fixedly installed at the output end of the second counterweight 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, and are parallel to the second direction. The third counterweight driving member 824 is used to drive the counterweight suction disc structure 821 to move along the second direction, so that the counterweight suction disc structure 821 moves back and forth between the standby material placing device 810 and the counterweight conveying line 730. By arranging the third counterweight driving member 824 as a structure comprising two linear cylinders, the space occupied by the third counterweight driving member 824 in the second direction when it is retracted can be reduced, so that other components of the box filling machine can have a larger range of motion.

[0097] Specifically, in the embodiment, the number of the counterweight carrying devices 820 is set to two, and the two counterweight carrying devices 820 share the same first counterweight driving member 822, that is, the second counterweight driving members 823 of the two counterweight carrying devices 820 are fixedly installed on the same counterweight connecting plate.

[0098] The number of the counterweight carrying devices 820 is set to two, so that the present material quantitative weighing assembly can simultaneously carry two materials into the containers of the counterweight conveying line 730. Compared with using a single counterweight carrying device 820, the two counterweight carrying devices 820 do not need to move back and forth repeatedly, so that the number of movement steps of the counterweight carrying device 820 can be reduced, and the working efficiency of the present material quantitative weighing assembly can be improved.

[0099] The material quantitative weighing method comprises:

[0100] Step S001, a worker randomly selects 10-20 materials of the same specification and weighs the selected materials, then calculates the average weight of the extracted materials, and 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 according to experience; for small, medium and large materials, the average weight of each specification is calculated respectively;

[0101] Step S002, a plurality of materials are carried to a plurality of standby material placing devices 810, so that each standby material placing device 810 has a single material therein;

[0102] Step S003, the container is conveyed to the weighing conveying line 720 by the empty container feeding conveying line 710, the first weighing module is zeroed, and then other components of the box filling machine supply containers to the empty container feeding conveying line 710;

[0103] Step S004, the material is picked up and placed in the container on the weighing conveying line 720, the first weighing module starts to accumulate the weight, sets the target weight as T0, the target weight T0 is set according to the requirement, the accumulated weight is T1, ΔT = T0-T1;

[0104] Step S005, when ΔT < G, the weighing conveying line 720 conveys the container filled with the material to the weight compensation conveying line 730;

[0105] Step S006, the weight compensation control module carries out single or two weight combinations of the material in the preparatory material placing device 810, the weight compensation control module selects the weight combination closest to ΔT from multiple combinations, and the weight compensation control module controls the weight compensation carrying device 820 to pick up the material corresponding to the weight combination;

[0106] Step S007, the weight compensation carrying device 820 carries the picked-up material to the container on the weight compensation conveying line 730, and the weight compensation step is completed;

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

[0108] The number of weighing conveying assemblies is set to four, and the four weighing conveying assemblies are symmetrically arranged on both sides of the material conveying line 110 in two groups. The two weighing conveying assemblies located on the same side of the material conveying line 110 are respectively set as the second assembly 140 and the first assembly 130.

The box-out conveying line 400 is arranged in the up-down direction along the material conveying starting end, and the conveying direction of the box-out conveying line 400 is arranged perpendicular to the material conveying direction. Specifically, in the embodiment, the box-out conveying line 400 is arranged above the material conveying starting end. Since the length direction of the box filling machine is parallel to the material conveying direction, by arranging the conveying direction of the box-out conveying line 400 perpendicular to the material conveying direction, the box-out conveying line 400 extends along the width direction of the box filling machine. Multiple box filling machines can use the same box-out conveying line 400 to transport the packaging box filled with the material, thereby improving the utilization rate of the box-out conveying line 400.

[0111] The container conveying structure of the first assembly 130 is provided as a first boxing assembly 200. The first boxing assembly 200 comprises a first lifting conveying device 220, a boxing returning conveying line 230, and a second lifting conveying device 240.

The box conveying structure 520 is used for conveying the packaging box from the first box conveying end to the second box conveying end. The box conveying structure 520 can selectively convey the packaging box to the empty container feeding conveying line 710 of the first assembly 130 or the empty container feeding conveying line 710 of the second assembly 140, so as to realize the diversion of the packaging box.

[0133] Specifically, in the embodiment, the box feeding conveying structure 520 comprises a box feeding main conveying line 521 and a box feeding lifting conveying device 522. The two sides of the box feeding main conveying line 521 and the box feeding lifting conveying device 522 are provided with baffle plates 611 for limiting the packaging boxes.

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

[0135] Specifically, in the embodiment, the box feeding main conveying line 521 comprises two box feeding belts which are parallel and horizontally arranged. The box feeding belts are conventional belt conveyors, and the two box feeding belts move synchronously.

[0136] The box feeding lifting conveying device 522 comprises a belt conveyor and a lifting driving structure. The lifting driving structure drives the belt conveyor to move up and down, and the belt conveyor drives the packaging boxes to move in the same direction as the material conveying direction or in the opposite direction to the material conveying direction, so that the packaging boxes enter the first assembly 130 or the second assembly 140, thereby realizing the diversion of the packaging boxes and meeting the requirement of multi-station material loading.

[0139] When the packaging box needs to be taken out, the suction disc driving member 532 drives the suction disc structure 531 to approach the packaging box taking-out position. The suction disc structure 531 adsorbs the lowermost packaging box at the packaging box taking-out position. Then, the suction disc driving member 532 drives the suction disc structure 531 to move away from the packaging box taking-out position. When the height of the suction disc structure 531 is lower than the conveying plane of the box feeding belt, the packaging box is blocked by the box feeding belt and cannot continue to be transported downward, so that the suction disc structure 531 is separated from the packaging box. Then, the box feeding belt can transport the packaging box.

[0140] The implementation process of the scheme is that the box taking device 530 first takes the packaging box from the packaging box placing device 510, and then the box conveying line 521 transports the packaging box to the box conveying and lifting device 522. After the packaging box moves to the box conveying and lifting device 522, the box conveying and lifting device 522 drives the packaging box to ascend, and then the box conveying and lifting device 522 drives the packaging box into the first box loading assembly 200 or the second box loading assembly 300.

[0141] The packaging box in the first box loading assembly 200 is transported by the first box loading conveying line 210 to move away from the box conveying line 400. During the transportation of the packaging box by the first box loading conveying line 210, the materials are carried into the packaging box by other components, so as to realize the loading of the materials. When the packaging box is transported to the first lifting conveying device 220, the first lifting conveying device 220 drives the packaging box to move upward. When the packaging box moves to the first high-position output 222, the first lifting conveying device 220 drives the packaging box into the box returning conveying line 230. The box returning conveying line 230 drives the packaging box to move close to the box conveying line 400. Finally, the box returning conveying line 230 transports the packaging box to the second lifting conveying device 240. Then, the packaging box is transported by the second lifting conveying device 240 to move from the second high-position input 242 to the second low-position output 241. When the packaging box is conveyed to the second low-position output 241, the second lifting conveying device 240 conveys the packaging box to the box conveying line 400.

[0142] The packaging box in the second box loading assembly 300 is transported by the second box loading conveying line 310 to move close to the box conveying line 400. During the transportation of the packaging box by the second box loading conveying line 310, the materials are carried into the packaging box by the material sorting equipment 005, so as to realize the loading of the materials. When the packaging box is transported to the third lifting conveying device 320, the third lifting conveying device 320 drives the packaging box to move upward. When the packaging box moves to the third high-position output 322, the third lifting conveying device 320 conveys the packaging box to the box conveying line 400.

[0143] By arranging the first box loading assembly 200 and the second box loading assembly 300, the working efficiency of the box loading machine can be improved.

[0144] By arranging the box returning conveying line 230, the first lifting conveying device 220, the second lifting conveying device 240, and other components, the box conveying line 400 and the material conveying line 110 can be arranged at the same end, so that the overall structure of the box loading machine is more compact, and the use of the previous arrangement of the box conveying line 400 and the material conveying line 110 at both ends of the box loading machine can be avoided, so that the factory space occupied by the box loading machine is reduced.
