Description

Technical Field

[0001] The invention relates to the technical field of production and processing of agricultural product packaging boxes, and in particular to a stacking device and method used in production and processing of packaging boxes. Background Art

[0002] As the name implies, packaging boxes are boxes used to package products. They can be classified by material, such as paper boxes, iron boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated packaging boxes, PVC boxes, etc. They can also be classified by product name, such as moon cake boxes, tea boxes, wolfberry boxes, candy boxes, exquisite gift boxes, local specialty boxes, wine boxes, chocolate boxes, food and medicine health care boxes, food packaging boxes, tea packaging boxes, pencil cases, etc. After the production and processing of agricultural products, they usually need to be placed in customized packaging boxes for packaging to ensure the safety of agricultural products during transportation and improve the grade of agricultural products; and because the surface of the packaging box is printed with relevant information and advertising slogans about agricultural products, it can increase the sales volume of agricultural products, promote brands, enhance consumer trust and loyalty, and increase the added value of products. In the production and processing of agricultural product packaging boxes, in order to save the space occupied by the packaging boxes, they often need to be stacked, so that the stacked multiple packaging boxes can be used in the subsequent packaging process of agricultural products. With the help of relevant packaging equipment, the agricultural products can be packaged more quickly, thereby improving the efficiency of agricultural product packaging and indirectly improving the production efficiency of agricultural products.

[0003] In the prior art, when the related stacking device is used to automatically stack the produced and processed agricultural product packaging boxes, although the automatic stacking processing of the agricultural product packaging boxes can be achieved with a high degree of automation, and there is no need for manual stacking of the agricultural product packaging boxes in sequence, after multiple agricultural product packaging boxes are stacked to a certain height in the device, the multiple agricultural product packaging boxes will be affected by the vibration caused by the operation of the device, so that the stacked multiple agricultural product packaging boxes have the risk of tilting to one side and collapsing. When such an unexpected situation occurs, the efficiency of the device for automatically stacking the multiple agricultural product packaging boxes will be greatly reduced, so that the stacking device in the prior art cannot meet people's demand for rapid production and processing of agricultural product packaging boxes, thereby affecting the efficiency of subsequent agricultural product packaging. Summary of the invention

[0008] Optionally, two second electric telescopic rods are installed on the outer walls of both sides of the two sleeve plates, and the telescopic ends of the two second electric telescopic rods are installed with limit plates. The bottom plate and the base are connected by two lifting frames.

[0009] Optionally, a first sliding groove is provided on the outer walls on both sides of the mounting frame, and a first sliding block is installed inside the two first sliding grooves, and the two first sliding blocks are rotatably connected to the first mounting plate and the second mounting plate at one end away from the first sliding groove, respectively, and two electromagnets are installed on the outer walls of the first mounting plate and the second mounting plate close to the mounting frame, and cylindrical friction blocks are installed at both ends of one of the driving shafts, and rubber layers matching the friction blocks are provided on the tops of the first mounting plate and the second mounting plate.

[0010] Optionally, a second slide groove is provided on the top of the first mounting plate, a second slider is installed inside the second slide groove, the top end of the second slider is connected to the bottom end of the movable frame, and a plurality of first industrial cameras are installed at the bottom of the movable frame.

[0011] Optionally, the detection mechanism includes a third slide groove opened on the outer wall of the movable frame on the side close to the conveyor belt, a third slider is installed inside the third slide groove, a second rotating plate is installed on the end of the third slider away from the third slide groove through a rotating shaft, and a plurality of second industrial cameras are installed on the bottom of the second rotating plate.

[0012] Optionally, two fourth sliding grooves are opened at the bottom of the second rotating plate, and fourth sliders are installed inside the two fourth sliding grooves. Two clamping plates are arranged at the bottom of the second rotating plate, one of the fourth sliders is fixedly connected to one of the clamping plates, and the other fourth slider is rotatably connected to the other clamping plate.

[0013] Optionally, a first sliding groove is provided at the bottom of the second mounting plate, a first sliding block is slidably installed inside the first sliding groove, and one end of the first sliding block away from the first sliding groove is connected to the top end of the vertical rod.

[0014] Optionally, the auxiliary supporting mechanism includes a second sliding groove formed on the outer wall of a side of the vertical rod close to the conveyor belt, a second sliding block is installed inside the second sliding groove, a rectangular plate is rotatably installed on the end of the second sliding block away from the second sliding groove, a supporting plate is installed on one end of the rectangular plate, two through grooves are formed inside the supporting plate, two fixed blocks are installed on the outer walls on both sides of the rectangular plate, third electric telescopic rods are installed on the outer walls of the two fixed blocks close to the support plate, a moving block is commonly installed on the telescopic ends of the two third electric telescopic rods, and a soft pad is installed on the outer wall of the moving block close to the through groove.

[0015] Optionally, a stacking method for packaging box production and processing includes the stacking device described above, and the stacking method further includes the following steps:

[0016] Step 1: The packaging boxes to be stacked are transferred to the top of the conveyor belt through other conveying equipment, and the two lifting racks are controlled to extend upward, driving the bottom plate to move upward to a position flush with the top of the conveyor belt. The conveyor belt drives multiple packaging boxes to be transported toward the right end. The first packaging box that falls from the top of the conveyor belt will fall inside the sleeve. Then the two lifting racks are controlled to slowly retract downward, driving the sleeve to descend, so that the second packaging box that falls from the top of the conveyor belt falls on top of the first packaging box. The above operation is repeated for subsequent multiple packaging boxes, so that multiple packaging boxes are automatically stacked inside the sleeve.

[0017] Step 2: After a sufficient number of packaging boxes are stacked inside one of the sleeves, the two limit plates inside the sleeve are controlled to move in the approaching direction to tightly abut the two sides of the multiple stacked packaging boxes, and then the first rotating plate is controlled to drive the two sleeves to rotate and exchange positions, and the sleeve with a sufficient number of packaging boxes stacked inside is rotated to the end away from the mounting frame, and the two first electric telescopic rods are controlled to drive the push plate to automatically push the stacked multiple packaging boxes out from the inside of the sleeve to the top of the pre-placed tray, completing the stacking of the multiple packaging boxes. At this time, the other sleeve is rotated to a position close to the mounting frame to continue stacking the subsequent packaging boxes;

[0018] Step 3: When the packaging box is conveyed to the right at the top of the conveyor belt, multiple second industrial cameras are controlled to automatically identify and detect the appearance of the packaging box. If there is a defect in the appearance of a certain packaging box, the third slider is controlled to drive the second rotating plate to move downward and adjust until the two clamps are in contact with the top of the conveyor belt. The two clamps are controlled to clamp and fix the packaging box. As the third slider drives the second rotating plate to move upward to a specified height, the second rotating plate is controlled to flip, and one of the clamps is controlled to rotate downward to a horizontal state. The other fourth slider is controlled to drive the other clamp to push the packaging box to fall downward from the top of the second rotating plate and be discharged, so that the defective packaging box is automatically removed;

[0019] Step 4: Since the length of the packaging box is less than the maximum adjustment distance of the two clamps, the second industrial camera finds that the packaging box on the top of the conveyor belt is skewed, and controls the third slider to drive the second rotating plate to move downward, so that the two clamps move to both sides of the skewed packaging box, and use the two clamps to move in a direction close to each other to correct the packaging box with position deviation;

[0020] Step 5: After the multiple packaging boxes are stacked to a certain height, control the first sliding block to drive one side outer wall of the support plate to abut against one side outer wall of the multiple packaging boxes stacked inside the sleeve, so that the support plate can provide auxiliary support for the stacked multiple packaging boxes, ensuring that the multiple packaging boxes are stacked neatly and orderly inside the sleeve.

[0021] The beneficial effects of the present invention are:

[0022] 1. In the present invention, when multiple packaging boxes are stacked inside a sleeve, two limiting plates can be used to limit and fix the two sides of the multiple packaging boxes, and the auxiliary supporting mechanism provided in combination can provide support and assistance to the other sides of the multiple packaging boxes, thereby limiting and fixing the multiple packaging boxes on all sides after stacking, thereby preventing the multiple packaging boxes from collapsing during the stacking process, improving the safety of the multiple packaging boxes during the stacking process, and further improving the efficiency of the device in stacking the multiple packaging boxes.

[0023] 2. In the present invention, two sets of plates are provided to alternately stack a plurality of packaging boxes, thereby achieving the effect of continuous stacking of a plurality of packaging boxes, and further improving the stacking efficiency of a plurality of packaging boxes.

[0024] 3. In the present invention, when a packaging box falls on the top of the conveyor belt and is conveyed to the right, the multiple second industrial cameras at the bottom of the second rotating plate can be controlled to automatically identify and detect the appearance of the packaging box. If there is a defect in the appearance of a certain packaging box, the multiple components of the detection mechanism can cooperate with each other to automatically remove the defective packaging box, thereby avoiding the subsequent stacking of defective packaging boxes and reducing work efficiency.

[0025] 4. In this invention, since the length of the packaging box is less than the maximum adjustment distance of the two clamps, when the second industrial camera finds that the packaging box on the top of the conveyor belt is skewed and affects the subsequent stacking, it can control the third slider to drive the second rotating plate to move downward, so that the two clamps move to both sides of the skewed packaging box. With the help of the two clamps moving in a direction close to each other, the packaging box with a position deviation can be corrected to avoid the subsequent entry into the interior of the sleeve and affecting the stacking stability of other packaging boxes.

[0048] As a technical optimization solution of the present invention, a stacking method for packaging box production and processing includes the stacking device described above, and the stacking method also includes the following steps:

[0049] Step 1: The packaging boxes to be stacked are transferred to the top of the conveyor belt 4 through other conveying equipment, and the two lifting frames are controlled to extend upward, driving the bottom plate 5 to move upward to a position flush with the top of the conveyor belt 4. The conveyor belt 4 drives multiple packaging boxes to be transported toward the right end, and the first packaging box falling from the top of the conveyor belt 4 will fall inside the sleeve plate 7. Then, the two lifting frames are controlled to slowly retract downward, driving the sleeve plate 7 to descend, so that the second packaging box falling from the top of the conveyor belt 4 falls on the top of the first packaging box. The above operation is repeated for subsequent multiple packaging boxes, so that multiple packaging boxes are automatically stacked inside the sleeve plate 7;

[0050] Step 2: After a sufficient number of packaging boxes are stacked inside one of the sleeve plates 7, the two limit plates 15 inside the sleeve plate 7 are controlled to move in the direction of approaching each other, so that the two sides of the multiple stacked packaging boxes are tightly abutted, and then the first rotating plate 6 is controlled to drive the two sleeve plates 7 to rotate and exchange positions, and the sleeve plate 7 with a sufficient number of packaging boxes stacked inside is rotated to the end away from the mounting frame 3, and the two first electric telescopic rods 18 are controlled to drive the push plate 17 to automatically push the stacked multiple packaging boxes out from the inside of the sleeve plate 7 to the top of the pre-placed tray, so as to complete the stacking of multiple packaging boxes. At this time, the other sleeve plate 7 is rotated to a position close to the mounting frame 3, and the subsequent packaging boxes are continued to be stacked;

[0051] Step 3: When the packaging box is conveyed to the right at the top of the conveyor belt 4, the multiple second industrial cameras 29 are controlled to automatically identify and detect the appearance of the packaging box. If there is a defect in the appearance of a certain packaging box, the third slider 26 is controlled to drive the second rotating plate 13 to move downward and adjust until the two clamping plates 27 are in contact with the top of the conveyor belt 4, and the two clamping plates 27 are controlled to clamp and fix the packaging box. As the third slider 26 drives the second rotating plate 13 to move upward to a specified height, the second rotating plate 13 is controlled to flip, and one of the clamping plates 27 is controlled to rotate downward to a horizontal state, and the other fourth slider 30 is controlled to drive the other clamping plate 27 to push the packaging box to fall downward from the top of the second rotating plate 13 and be discharged, so as to automatically remove the defective packaging box;

[0052] Step 4: Since the length of the packaging box is less than the maximum adjustment distance of the two clamping plates 27, the second industrial camera 29 finds that the packaging box on the top of the conveyor belt 4 is skewed, and controls the third slider 26 to drive the second rotating plate 13 to move downward, so that the two clamping plates 27 move to both sides of the skewed packaging box, and use the two clamping plates 27 to move in a direction close to each other to correct the packaging box with a position deviation;

[0053] Step 5: After the multiple packaging boxes are stacked to a certain height, control the first sliding block 39 to drive one side outer wall of the support plate 14 to abut against one side outer wall of the multiple packaging boxes stacked inside the sleeve plate 7, so that the support plate 14 can auxiliary support the stacked multiple packaging boxes to ensure that the multiple packaging boxes are stacked neatly and orderly inside the sleeve plate 7.

[0054] In the present invention, after the packaging box of agricultural products has gone through the processes of design, plate making, paper selection, printing process, die cutting, folding and bonding, the packaging box that has been folded and processed into a three-dimensional shape can be transferred to the top of the conveyor belt 4 through other conveying equipment, and the two lifting frames 37 are controlled to extend upward, driving the bottom plate 5 to move upward to a position flush with the top of the conveyor belt 4. Through the rotation of the conveyor belt 4, multiple packaging boxes are driven to be transported toward the right end. The first packaging box that falls from the top of the conveyor belt 4 will fall into one of the sleeves 7 close to the mounting frame 3. Then the two lifting frames 37 can be controlled to slowly shrink downward, driving the bottom plate 5 and the sleeve 7 and other multiple components to slowly descend together, so that the second packaging box that falls from the top of the conveyor belt 4 falls on the top of the first packaging box. The subsequent multiple packaging boxes can repeat the above operation and are stacked in sequence inside the sleeve 7.

[0055] After a sufficient number of packaging boxes are stacked inside one of the sleeve plates 7, the telescopic ends of the two second electric telescopic rods 16 on the outer walls of both sides of the sleeve plate 7 can be controlled to extend together, driving the two limit plates 15 to move in the direction of approaching, so that the outer walls on the adjacent side of the two limit plates 15 can be tightly abutted against both sides of the multiple stacked packaging boxes, which can not only clamp and limit the multiple packaging boxes, but also have the effect of pushing and shaping the multiple packaging boxes, ensuring that the multiple packaging boxes are neatly stacked inside the sleeve plate 7, and then the first rotating plate 6 is controlled to drive the two sleeve plates 7 to rotate and exchange positions, and the sleeve plate 7 with a sufficient number of packaging boxes stacked inside is rotated to the end away from the mounting frame 3, and the telescopic ends of the multiple second electric telescopic rods 16 are controlled to retract together, and then Then, the telescopic ends of the two first electric telescopic rods 18 are controlled to extend together, driving the push plate 17 to automatically push the stacked multiple packaging boxes from the inside of the sleeve plate 7 to the top of the pre-placed pallet, thereby completing the stacking of multiple packaging boxes; at this time, the other sleeve plate 7 rotates to a position close to the mounting frame 3, and can continue to stack the subsequent packaging boxes, so that the two sleeve plates 7 work alternately, and the effect of continuous stacking of multiple packaging boxes is achieved, thereby improving the stacking efficiency of the packaging boxes, and then indirectly improving the subsequent packaging efficiency of agricultural products, thereby reducing the cost of agricultural products in the production process, improving production efficiency, improving the quality of agricultural products, enhancing the competitiveness of agricultural products, and reducing the labor cost of agricultural products in the packaging process.

[0056] When the packaging box falls on the top of the conveyor belt 4 and is transported to the right, the multiple second industrial cameras 29 at the bottom of the second rotating plate 13 can be controlled to automatically identify and detect the appearance of the packaging box. If there is a defect in the appearance of a certain packaging box, the conveyor belt 4 can be controlled to reduce the conveying speed or suspend operation, and the third slider 26 can be controlled to slide downward inside the third slide groove 25, driving the second rotating plate 13 to move downward together until the bottom ends of the two clamping plates 27 move to abut against the top of the conveyor belt 4. At this time, the two clamping plates 27 are located on both sides of the packaging box, and the two fourth sliders 30 are controlled to move toward the approaching direction inside the corresponding fourth slide groove 28. The third slider 26 drives the second rotating plate 13 to move upward to a specified height, and the second rotating plate 13 is controlled to flip, and one of the clamps 27 is controlled to rotate downward on the top of the fourth slider 30 to be horizontal, and the other fourth slider 30 is controlled to drive the other clamp 27 to move toward one of the clamps 27, so that the packaging box can be pushed to fall downward from the top of the second rotating plate 13 and be discharged, so as to achieve the effect of automatically rejecting the defective packaging boxes, thereby avoiding the subsequent stacking of defective packaging boxes and reducing the work efficiency.

[0057] Furthermore, since the length of the packaging box is less than the maximum adjustment distance of the two clamps 27, when the second industrial camera 29 finds that the packaging box on the top of the conveyor belt 4 is skewed and affects the subsequent stacking, it can control the third slider 26 to drive the second rotating plate 13 to move downward, so that the two clamps 27 move to the two sides of the skewed packaging box. With the help of the two clamps 27 moving in a direction close to each other, the packaging box with a position deviation can be corrected to avoid the subsequent entry into the interior of the sleeve plate 7 and affecting the stacking stability of other packaging boxes.

[0058] After the multiple packaging boxes enter the inner part of the sleeve plate 7 and are stacked to a certain height, although two limiting plates 15 are arranged inside the sleeve plate 7 to limit the two sides of the multiple packaging boxes, the stacking height of the multiple packaging boxes is relatively high, and there is still a risk of tipping over from the opening on one side of the sleeve plate 7. Figure 2 and Fig. 9As shown, at this time, the first sliding block 39 can be controlled to move inside the first sliding groove 38 toward the direction close to the sleeve plate 7, thereby driving the outer wall of one side of the support plate 14 to abut against the outer wall of one side of the multiple packaging boxes stacked inside the sleeve plate 7, so that at this time, the support plate 14 can have an auxiliary supporting effect on the multiple packaging boxes stacked to a higher level, and the second sliding block 32 can be used to move up and down in the second sliding groove 31 for adjustment, thereby driving the support plate 14 to have a supporting effect on the multiple stacked packaging boxes at different heights, and as the support plate 14 moves up and down, it can also have a pushing and correcting effect on one side of the multiple stacked packaging boxes, thereby ensuring that the multiple packaging boxes are stacked more neatly and orderly inside the sleeve plate 7, reducing the risk of the stacked multiple packaging boxes tipping over, and ensuring that the stacking of the multiple packaging boxes proceeds smoothly.

[0059] When the second slider 23 is controlled to move slowly toward the right end inside the second slide groove 22, the second rotating plate 13 can be driven to push the multiple packaging boxes on the top of the conveyor belt 4, and the multiple packaging boxes can be slowly pushed down from the right end of the conveyor belt 4 to the inside of the sleeve plate 7 in sequence, so that the multiple packaging boxes placed on the top of the conveyor belt 4 can continue to be stacked, thereby avoiding the problem that the multiple packaging boxes on the top of the conveyor belt 4 hinder the staff from repairing the conveyor belt 4, thereby improving the maintenance efficiency of the conveyor belt 4.

[0060] If the packaging box is relatively soft, it is not possible to use the above-mentioned method of directly pushing the packaging box on the top of the conveyor belt 4 by means of the second rotating plate 13 to convey and unload the material. Figure 1 , Figure 5 , Figure 6 , Fig. 9As shown, at this time, the multiple electromagnets 21 can be controlled to be powered off first to release the magnetic fixation with the outer wall of the mounting frame 3, and then the two first sliders 20 can be controlled to drive the first mounting plate 11 and the second mounting plate 12 to move toward the left end together in the corresponding first slide groove 19, so that the first mounting plate 11 and the second mounting plate 12 can rub the circular outer walls of the two friction blocks 10 with the help of the rubber layer arranged on the top while moving toward the left end, so as to drive the drive shaft to rotate in the clockwise direction, and drive the conveyor belt 4 to rotate slowly in the clockwise direction, so that the multiple packaging boxes on the top of the conveyor belt 4 can still be transported to the right for a distance, and after the two first sliders 20 move to the rightmost end in the corresponding first slide groove 19, the first mounting plate 11 and the second mounting plate 12 are controlled to rotate slightly downward together, so that the first mounting plate 11 and The second mounting plates 12 are both disengaged from the outer walls of the corresponding friction blocks 10, and then the two first sliders 20 are controlled to move toward the right end and reset inside the corresponding first slide grooves 19, and after the two first sliders 20 are moved and reset, the first mounting plate 11 and the second mounting plate 12 are controlled to rotate upward and reset together, and the steps of the two first sliders 20 driving the first mounting plate 11 and the second mounting plate 12 to frictionally rotate the two friction blocks 10 toward the left end are repeated, so that one of the driving shafts can continue to drive the conveyor belt 4 to rotate slowly, and can drive all the multiple packaging boxes on the top of the conveyor belt 4 to be transported and stacked to the right end, so that the first mounting plate 11 and the second mounting plate 12 cooperate with each other, and can also perform auxiliary transportation and unloading processing on such relatively soft packaging boxes, further improving the applicability of the first mounting plate 11 and the second mounting plate 12.

[0061] If it is only necessary to correct multiple packaging boxes with the help of two clamping plates 27 and transport the corrected packaging boxes to other conveying equipment, the bottom plate 5 can be removed from the top of the base 1 at this time, and then the first mounting plate 11 can be driven to move to the right with the help of the first slider 20, and the moving frame 8 and other components can be driven to move and disengage from the top of the mounting frame 3, and then the third slider 26 is controlled to move downward to the bottom end inside the third slide groove 25, and then the second rotating plate 13 is controlled to rotate and adjust, so that the higher end of the second rotating plate 13 abuts against the right end of the conveyor belt 4, and the lower end of the second rotating plate 13 abuts against the feed port of other conveying equipment, so that the second rotating plate 13 can be used as a guide plate at this time, which is convenient for guiding and transporting the packaging boxes to other conveying equipment, thereby improving the applicability of the second rotating plate 13.

[0062] After the device completes the stacking process of the packaging boxes, the surface of the conveyor belt 4 will inevitably be attached with impurities brought by the packaging boxes. At this time, the rectangular plate 33 and the support plate 14 can be controlled to rotate 90 degrees, driving the horizontal plane on one side of the support plate 14 to rotate to a state parallel to the conveyor belt 4, and then the telescopic ends of the multiple third electric telescopic rods 35 are controlled to extend together, driving the two soft pads 36 to extend from the corresponding through grooves 34, and with the help of the second sliding block 32, slide upward inside the second sliding groove 31, driving the support plate 14 to move upward together until the two soft pads 36 abut against the conveyor belt 4. At this time, as the conveyor belt 4 rotates, the two soft pads 36 can automatically scrape and clean the impurities on the surface of the conveyor belt 4 to avoid secondary pollution of the impurities to the subsequently transported packaging boxes, thereby facilitating the subsequent use of the conveyor belt 4.

10. A stacking method for packaging box production and processing, characterized in that: The stacking device according to claim 9 is included, and the stacking method further comprises the following steps: Step 1: The packaging boxes to be stacked are transferred to the top of the conveyor belt (4) through other conveying equipment, and the two lifting racks are controlled to extend upward, driving the bottom plate (5) to move upward to a position flush with the top of the conveyor belt (4), and the conveyor belt (4) drives multiple packaging boxes to be transported toward the right end. The first packaging box that falls from the top of the conveyor belt (4) will fall into the sleeve plate (7). Then, the two lifting racks are controlled to slowly retract downward, driving the sleeve plate (7) to descend, so that the second packaging box that falls from the top of the conveyor belt (4) falls on the top of the first packaging box. The above operation is repeated for subsequent multiple packaging boxes, so that multiple packaging boxes are automatically stacked inside the sleeve plate (7); Step 2: After a sufficient number of packaging boxes are stacked inside one of the sleeve plates (7), the two limit plates (15) inside the sleeve plate (7) are controlled to move in a direction close to each other, so as to tightly abut the two sides of the multiple stacked packaging boxes. Then, the first rotating plate (6) is controlled to drive the two sleeve plates (7) to rotate and exchange positions, and the sleeve plate (7) with a sufficient number of packaging boxes stacked inside is rotated to the end away from the mounting frame (3). The two first electric telescopic rods (18) are controlled to drive the push plate (17) to automatically push the stacked multiple packaging boxes out from the inside of the sleeve plate (7) to the top of the pre-placed tray, thereby completing the stacking of the multiple packaging boxes. At this time, the other sleeve plate (7) is rotated to a position close to the mounting frame (3), and the subsequent packaging boxes are continued to be stacked. Step three: When the packaging box is conveyed to the right at the top of the conveyor belt (4), the plurality of second industrial cameras (29) are controlled to automatically identify and detect the appearance of the packaging box. If there is a defect in the appearance of a certain packaging box, the third slider (26) is controlled to drive the second rotating plate (13) to move downward and adjust until the two clamping plates (27) are in contact with the top of the conveyor belt (4). The two clamping plates (27) are controlled to clamp and fix the packaging box. As the third slider (26) drives the second rotating plate (13) to move upward to a specified height, the second rotating plate (13) is controlled to flip, and one of the clamping plates (27) is controlled to rotate downward to a horizontal state. The other fourth slider (30) is controlled to drive the other clamping plate (27) to push the packaging box to fall downward from the top of the second rotating plate (13) and be discharged, so that the defective packaging box is automatically removed. Step 4: Since the length of the packaging box is less than the maximum adjustment distance of the two clamping plates (27), the second industrial camera (29) finds that the packaging box on the top of the conveyor belt (4) is skewed, and controls the third slider (26) to drive the second rotating plate (13) to move downward, so that the two clamping plates (27) move to both sides of the skewed packaging box, and use the two clamping plates (27) to move in a direction close to each other, so as to correct the packaging box with a position deviation; Step 5: After the multiple packaging boxes are stacked to a certain height, the first sliding block (39) is controlled to drive the outer wall of one side of the support plate (14) to abut against the outer wall of one side of the multiple packaging boxes stacked inside the sleeve plate (7), so that the support plate (14) can provide auxiliary support for the stacked multiple packaging boxes, thereby ensuring that the multiple packaging boxes are stacked neatly and orderly inside the sleeve plate (7).
