Description

Technical Field

[0001] The present invention relates to the field of transporting flat packaging boxes, and particularly to a device for picking up, identifying, and separating packaging boxes. Background Art

[0002] Paper packaging boxes are applied in various industries. Before being formed, a paper packaging box is a flat cardboard in a unfolded state (referred to as a "flat packaging box" for short). When the flat packaging boxes come in, they are stacked one on top of another. A suction cup transfers the stacked flat packaging boxes to a conveyor line one by one to achieve the picking up and separation of the flat packaging boxes. Then, an operator holds a barcode scanning device to scan and identify the barcode on the flat packaging box on the conveyor line to confirm that the barcode information on the flat packaging box is consistent with the barcode information entered in the system, ensuring that the barcode on the flat packaging box is correct and there is no miscode or barcode damage. Some manufacturers install an identification head above the conveyor line to identify the barcode on the flat packaging box. However, this identification method requires a very slow conveying speed of the conveyor line. Otherwise, the identification head above the conveyor line cannot accurately identify the barcode on the flat packaging box, resulting in misfeeding and missed inspection. Moreover, the picking up, separation, and barcode identification of the flat packaging boxes are carried out in different processes successively, which also leads to a relatively low overall efficiency of forming the flat packaging boxes. Summary of the Invention

[0003] The object of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a device for picking up, identifying, and separating packaging boxes.

[0004] According to one aspect of the present invention, there is provided a device for picking up, identifying, and separating packaging boxes, including a conveyor line and a vacuum suction cup. The vacuum suction cup is used to transfer the stacked flat packaging boxes to the conveyor line, and further includes: A driving component; A turntable, the conveyor line is located below the turntable; A driving disk, the driving disk is arranged coaxially with the turntable, a connecting column is provided between the driving disk and the turntable, and the driving component drives the driving disk to rotate; A mounting rod, the mounting rod is arranged on the turntable and is perpendicularly arranged with respect to the turntable, and the vacuum suction cup is arranged on the mounting rod; An identification head for identifying the barcode on the flat packaging box, the identification head is located on the side of the turntable; Three groove-shaped photoelectric sensors distributed at the three vertices of a triangle. A detection disk is provided coaxially on the driving disk, a notch is provided on the periphery of the detection disk, and the edge of the detection disk can pass through the U-shaped detection groove of the groove-shaped photoelectric sensor; and A controller, the groove-shaped photoelectric sensor is electrically connected to the controller, and the controller is electrically connected to the driving component.

[0005] For the device of the present invention, flat packaging boxes stacked together are placed in a bin with an open bottom. The bin is located on the side of a turntable. The surface of the barcode of the flat packaging box in the bin faces away from the vacuum suction cup. The vacuum suction cup on the mounting rod sucks the bottommost flat packaging box in the bin. The driving component drives the driving disk to rotate. The driving disk drives the turntable to rotate synchronously through a connecting column. The turntable drives the mounting rod to rotate simultaneously. When the mounting rod on the turntable rotates to the position of the recognition head, the flat packaging box sucked by the vacuum suction cup on the mounting rod faces the recognition head for the recognition head to identify. Then, as the turntable continues to rotate, the mounting rod on the turntable rotates above the conveyor line, and the vacuum suction cup on the mounting rod places the sucked flat packaging box on the conveyor line. The turntable continues to rotate. When the mounting rod on the turntable rotates to the position of the bin, the vacuum suction cup sucks the next flat packaging box. During the rotation of the turntable, when the notch on the detection disk rotates into the U-shaped detection groove of one of the groove type photoelectric sensors, the groove type photoelectric sensor is triggered and generates a switch signal. The groove type photoelectric sensor sends the switch signal to the controller, and the controller controls the driving component to pause for a certain period of time (such as 0.5S or 1S) to allow the vacuum suction cup on the mounting rod to suck the bottommost flat packaging box in the bin, the flat packaging box sucked by the vacuum suction cup on the mounting rod to be identified by the recognition head for the barcode, or the flat packaging box sucked by the vacuum suction cup on the mounting rod to be placed on the conveyor line. For the device of the present invention, one rotation of the turntable can complete the processes of taking materials, barcode recognition, and separation of flat packaging boxes, thereby improving the overall efficiency of the formation of flat packaging boxes.

[0006] Furthermore, it further includes a connecting cylinder, a first gear, a second gear, and a third gear. The first gear is sleeved on the connecting cylinder. The mounting rod penetrates through the turntable and is rotationally connected to the turntable. The second gear is sleeved on one end of the mounting rod and is fixedly connected to the mounting rod. The vacuum suction cup is arranged on the other end of the mounting rod. The third gear meshes with the first gear and the third gear meshes with the second gear. The third gear is located between the first gear and the second gear. The third gear is arranged on the turntable and can rotate on the turntable.

[0007] Therefore, the air pipes of the vacuum suction cups can be centrally connected to the connecting cylinder, and the connecting cylinder is connected to an external vacuum generator, reducing the number and length of the air pipes and improving the neatness of the device. Moreover, the bin with an open bottom for placing flat packaging boxes is usually located above the side of the turntable. When the turntable rotates counterclockwise, the third gear rolls along the first gear, driving the second gear to rotate clockwise. The second gear drives the mounting rod to rotate clockwise relative to the turntable on the turntable. The vacuum suction cups on the mounting rod that hold the flat packaging box also rotate clockwise relative to the turntable on the turntable, ensuring that the flat packaging box held by the vacuum suction cup does not interfere with the bottom of the bin and the bottommost flat packaging box not yet picked up in the bin, so that the flat packaging box held by the vacuum suction cup can be smoothly transferred to the position of the recognition head. The flat packaging box held by the vacuum suction cup also does not interfere with the conveyor line, so that the flat packaging box held by the vacuum suction cup can be smoothly transferred to the conveyor line. When the vacuum suction cup is separated from the conveyor line, the vacuum suction cup does not interfere with the flat packaging box on the conveyor line. When the vacuum suction cup rotates back to the position of the bin again, the vacuum suction cup does not interfere with the bottom of the bin and the bottommost flat packaging box not yet picked up in the bin, thus ensuring the smooth and efficient picking, bar code recognition, and separation of the flat packaging box. The first gear can make the turntable rotate smoothly as a whole.

[0008] Furthermore, the number of the mounting rods, the second gears, and the third gears is three each, and the number of the vacuum suction cups is nine. The mounting positions of the three mounting rods on the turntable are distributed at the three vertices of an equilateral triangle. The three second gears are respectively sleeved on one end of the three mounting rods and fixedly connected to the mounting rods. The three third gears are respectively located between the three second gears and the first gear. The number of the vacuum suction cups on each mounting rod is three.

[0009] Therefore, the three vacuum suction cups on each mounting rod can firmly hold the flat packaging box, preventing the flat packaging box from falling off during the transfer process. The vacuum suction cups on the three mounting rods can simultaneously and respectively perform picking, bar code recognition, and separation (the vacuum suction cup places the flat packaging box on the conveyor line), that is: when the vacuum suction cup on one mounting rod holds the flat packaging box for picking, the flat packaging box held by the vacuum suction cup on the second mounting rod faces the recognition head for the recognition head to recognize, and at the same time, the flat packaging box held by the vacuum suction cup on the third mounting rod is placed on the conveyor line, thereby greatly improving the efficiency of picking, bar code recognition, and separation of the flat packaging box.

[0010] Furthermore, the pitch diameter of the first gear is times the pitch diameter of the second gear, and the pitch diameter of the first gear is 3 times the pitch diameter of the third gear.

[0011] Therefore, when the turntable rotates 120 degrees, the vacuum suction cups on each mounting rod also rotate 120 degrees relative to the turntable, so that the flat packaging box sucked by the vacuum suction cup just rotates from the material taking position to the identification head position, and the barcode on the flat packaging box is facing the identification head. Also, the flat packaging box sucked by the vacuum suction cup just rotates from the barcode identification position to the conveyor line position, and the barcode on the flat packaging box is placed upward on the conveyor line.

[0012] Further, the three groove-shaped photoelectric sensors are distributed at the three vertices of an equilateral triangle.

[0013] Therefore, when the notch on the detection disk rotates into the U-shaped detection groove of one of the groove-shaped photoelectric sensors, the groove-shaped photoelectric sensor is triggered and generates a switch signal. The groove-shaped photoelectric sensor sends the switch signal to the controller, and the controller controls the driving component to pause for a certain period of time (such as 0.5S or 1S), so that the vacuum suction cup on one mounting rod sucks the bottommost flat packaging box in the bin, the flat packaging box sucked by the vacuum suction cup on the second mounting rod is for the identification head to identify the barcode, and the flat packaging box sucked by the vacuum suction cup on the third mounting rod is placed on the conveyor line. Then, the driving component drives the turntable to continue rotating, so that the vacuum suction cup sucks the bottommost flat packaging box in the next bin, the identification head identifies the barcode on the next flat packaging box, and the vacuum suction cup places the next flat packaging box on the conveyor line. When the notch on the detection disk rotates from the U-shaped detection groove of one groove-shaped photoelectric sensor to the U-shaped detection groove of the adjacent second groove-shaped photoelectric sensor, the notch rotates 120 degrees, and the turntable also rotates 120 degrees at the same time. One mounting rod just rotates from the material taking position to the identification position, the second mounting rod just rotates from the identification position to the separation (flat packaging box placed on the conveyor line) position, and the third mounting rod just rotates from the separation position to the material taking position.

[0014] Further, the identification head is a barcode reader.

[0015] Therefore, the barcode reader can identify the barcode information on the flat packaging box and compare it with the barcode information entered in the system. When the two pieces of information are consistent, the turntable continues to rotate. When the two pieces of information are inconsistent, it means that the barcode information on the flat packaging box is incorrect, and the flat packaging box is a misfed material. At this time, the driving component can be controlled to pause for the operator to confirm. When the identification head cannot identify the barcode information on the flat packaging box, it means that the barcode information on the flat packaging box is miscoded or damaged. At this time, the driving component can be controlled to pause for the operator to confirm.

[0016] Further, the identification head is a two-dimensional code reader.

[0017] Therefore, the QR code reader can identify the QR code information on the flat packaging box and compare it with the QR code information entered in the system. When the two pieces of information are consistent, the turntable continues to rotate. When the two pieces of information are inconsistent, it indicates that the QR code information on the flat packaging box is incorrect, and the flat packaging box is a misfed material. At this time, the driving component can be controlled to pause for the operator to confirm. When the recognition head cannot identify the QR code information on the flat packaging box, it indicates that the QR code information on the flat packaging box is miscoded or damaged. At this time, the driving component can be controlled to pause for the operator to confirm.

[0018] Further, the number of vacuum suction cups is three. The three vacuum suction cups are arranged in parallel on the mounting rod, and the axes of the vacuum suction cups are perpendicular to the mounting rod.

[0019] Therefore, the three vacuum suction cups arranged in parallel on the mounting rod can firmly hold the flat packaging box, ensuring that the flat packaging box will not fall off during the transfer process.

[0020] Further, it further includes a mounting plate. Both the driving component and the recognition head are arranged on the mounting plate, and the position of the recognition head on the mounting plate can be adjusted.

[0021] Therefore, the mounting plate can provide support for the driving component and other components. According to the position of the barcode on the flat packaging box, the position of the recognition head on the mounting plate can be adjusted to ensure that the recognition head can be directly opposite to the barcode on the flat packaging box.

[0025] Referring to Figures 1 to 6 , a device for taking, identifying, and separating packaging boxes, including a conveyor line 1, a vacuum suction cup 2, a driving component 3, a turntable 4, a mounting rod 5, an identification head 6, a driving disk 7, a connecting cylinder 8, a first gear 9, a second gear 10, a third gear 11, a groove-type photoelectric sensor 12, a controller, a detection disk 13, and a mounting plate 14.

[0026] Referring to Figure 2 , Figure 5 and Figure 6 , in this embodiment, the driving component 3 adopts a servo motor hollow rotary platform structure. The driving component 3 includes a servo motor 31 and a hollow rotary platform 32. The servo motor 31 is installed on the side of the hollow rotary platform 32. The rotating part 321 of the hollow rotary platform 32 is fixed on the driving disk 7 and is coaxially arranged. The servo motor 31 drives the hollow rotary platform 32 to rotate, and the hollow rotary platform 32 drives the driving disk 7 to rotate synchronously. The servo motor 31 is fixedly inserted in the mounting plate 14. The servo motor hollow rotary platform structure is a prior art and can directly adopt the existing servo motor hollow rotary platform structure on the market.

[0027] Referring to Figure 4, the turntable 4 and the driving disk 7 are coaxially arranged. The turntable 4 is annular. A connecting column 71 is fixed between the driving disk 7 and the turntable 4. When the driving component 3 drives the driving disk 7 to rotate, the driving disk 7 drives the turntable 4 to rotate synchronously through the connecting column 71. The driving disk 7 and the turntable 4 form a stable whole through the connecting column 71, which can ensure that the mounting rods 5 and the vacuum suction cups 2 on the turntable 4 rotate smoothly with the turntable 4.

[0028] Refer to Figures 1 to 3 , the mounting rod 5 is inserted through the turntable 4 and is rotatably connected to the turntable 4. A first bearing 51 is mounted on the mounting rod 5, and the first bearing 51 is inserted and fixed in the turntable 4. The mounting rod 5 can rotate on the turntable 4. The mounting rod 5 and the turntable 4 are perpendicularly arranged. The vacuum suction cup 2 is fixed on the mounting rod 5. The axis of the vacuum suction cup 2 is perpendicularly arranged with the mounting rod 5. In this embodiment, the number of vacuum suction cups 2 on one mounting rod 5 is three, and the three vacuum suction cups 2 are arranged in parallel on the mounting rod 5. The connecting cylinder 8 is inserted and accommodated in the hollow rotating platform 32, the driving disk 7, and the turntable 4. The connecting cylinder 8 does not contact the hollow rotating platform 32, the driving disk 7, and the turntable 4. One end of the connecting cylinder 8 is closed, and the other end is open. The open end of the connecting cylinder 8 is fixed on the mounting plate 14 ( Figure 5 as shown). A through hole is formed at the position on the mounting plate 14 where the end of the connecting cylinder 8 is mounted. The air pipes of the vacuum suction cups 2 can be centrally connected to the connecting cylinder 8. The connecting cylinder 8 is connected to an external vacuum generator. The vacuum generator can make the vacuum suction cups 2 generate negative pressure to suck the flat packaging box. The connecting cylinder 8 can reduce the number and length of the air pipes and improve the neatness of the device.

[0029] Refer to Figure 2 and Figure 3 , the first gear 9 is sleeved on the connecting cylinder 8, and the first gear 9 is fixedly connected to the connecting cylinder 8. The second gear 10 is sleeved on one end of the mounting rod 5, and the second gear 10 is fixedly connected to the mounting rod 5. The third gear 11 is located between the first gear 9 and the second gear 10. The third gear 11 meshes with the first gear 9, and the third gear 11 meshes with the second gear 10. The third gear 11 is mounted on the turntable 4 and can rotate on the turntable 4. Specifically, the rotating shaft 111 of the third gear 11 is inserted and fixed in the inner ring of a second bearing, and the second bearing is inserted and fixed in the turntable 4; the bottom of the bin with an open bottom for placing the flat packaging box is usually located above the side of the turntable ( Figure 7 as shown). When the turntable 4 rotates counterclockwise ( Figure 1When the middle turntable 4 rotates counterclockwise, the third gear 11 rolls along the first gear 9. The third gear 11 drives the second gear 10 to rotate clockwise. The second gear 10 drives the mounting rod 5 to rotate clockwise relative to the turntable 4 on the turntable 4. The vacuum suction cup 2 that sucks the flat packaging box on the mounting rod 5 also rotates clockwise relative to the turntable 4 on the turntable 4, ensuring that the flat packaging box sucked by the vacuum suction cup 2 will not interfere with the bottom of the silo and the flat packaging box at the bottom of the silo that has not been sucked. Thus, the flat packaging box sucked by the vacuum suction cup 2 is smoothly transferred to the position of the recognition head 6. The flat packaging box sucked by the vacuum suction cup 2 will not interfere with the conveyor line 1 either. Thus, the flat packaging box sucked by the vacuum suction cup 2 is smoothly transferred onto the conveyor line 1. When the vacuum suction cup 2 separates from the conveyor line 1, the vacuum suction cup 2 will not interfere with the flat packaging box on the conveyor line 1. When the vacuum suction cup 2 rotates back to the silo position again, the vacuum suction cup 2 will not interfere with the bottom of the silo and the flat packaging box at the bottom of the silo that has not been sucked, ensuring that the picking, barcode recognition, and separation of the flat packaging box are carried out smoothly and efficiently. The first gear 9 can make the driving disk 7, the turntable 4, and the components on the turntable 4 rotate smoothly as a whole.

[0030] Refer to Figures 1 to 3 , the number of the mounting rods 5, the second gears 10, and the third gears 11 is three each, and the number of the vacuum suction cups 2 is nine. The mounting positions of the three mounting rods 5 on the turntable 4 are distributed at the three vertices of an equilateral triangle. The three second gears 10 are respectively sleeved on one end of the three mounting rods 5 and fixedly connected to the mounting rods 5. The three third gears 11 are respectively located between the three second gears 10 and the first gear 9. The first gear 9, the second gear 10, and the third gear 11 are all located in the space between the driving disk 7 and the turntable 4. The number of the vacuum suction cups 2 on each mounting rod 5 is three. The three vacuum suction cups 2 on each mounting rod 5 can firmly suck the flat packaging box, preventing the flat packaging box from falling off during the transfer process. The vacuum suction cups 2 on the three mounting rods 5 can pick up materials, recognize barcodes, and separate (the vacuum suction cup 2 places the flat packaging box on the conveyor line 1) simultaneously and respectively. That is, when the three vacuum suction cups 2 on one mounting rod 5 suck the flat packaging box to pick up materials, the flat packaging box sucked by the three vacuum suction cups 2 on the second mounting rod 5 faces the recognition head 6 for the recognition head 6 to recognize. At the same time, the three vacuum suction cups 2 on the third mounting rod 5 place the sucked flat packaging box on the conveyor line 1, thus greatly improving the efficiency of picking up materials, barcode recognition, and separation of the flat packaging box.

[0031] Refer to Figures 1 to 3, in this embodiment, the pitch diameter of the first gear 9 is three times that of the second gear 10, and the pitch diameter of the first gear 9 is three times that of the third gear 11. The second gear 10 and the third gear 11 have the same specifications. In this way, when the turntable 4 rotates 120 degrees, the vacuum suction cup 2 on each mounting rod 5 also rotates 120 degrees relative to the turntable 4, so that the flat packaging box sucked by the vacuum suction cup 2 just rotates from the material taking position to the position of the recognition head 6 and the barcode on the flat packaging box faces the recognition head 6 exactly, and the flat packaging box sucked by the vacuum suction cup 2 just rotates from the barcode recognition position to the position of the conveyor line 1 and the barcode on the flat packaging box is placed upward on the conveyor line 1.

[0032] Refer to Figure 1 , the recognition head 6 is installed on the mounting plate 14. The recognition head 6 is located on the side of the turntable 4. The recognition head 6 is used to recognize the barcode on the flat packaging box. The recognition head 6 is a barcode reader or a QR code reader. The barcode reader or the QR code reader can recognize the barcode or QR code information on the flat packaging box and compare it with the barcode or QR code information entered in the system. When the two pieces of information are the same, the turntable 4 continues to rotate. When the two pieces of information are different, it means that the barcode or QR code information on the flat packaging box is incorrect, and the flat packaging box is a wrong material. At this time, the driving component 3 can be controlled to pause for the operator to confirm. When the recognition head 6 cannot recognize the barcode or QR code information on the flat packaging box, it means that the barcode or QR code information on the flat packaging box has an error code or is damaged. At this time, the driving component 3 can be controlled to pause for the operator to confirm.

[0033] The position of the recognition head 6 on the mounting plate 14 can be adjusted. The recognition head 6 can be installed on the mounting plate 14 through three mutually perpendicular sliding rods. According to the position of the barcode on the flat packaging box, the position of the recognition head 6 on the mounting plate 14 can be adjusted to ensure that the recognition head 6 can face the barcode on the flat packaging box exactly.

[0034] Refer to Figure 1 and Figure 5 , the mounting plate 14 can provide support for the driving component 3, the recognition head 6 and other components.

[0035] Refer to Figure 1, The conveyor line 1 is located below the turntable 4. The material picking position, barcode recognition position, and separation position (where the vacuum suction cup 2 places the flat packaging box on the conveyor line 1) of the vacuum suction cup 2 are distributed at the three vertices of an equilateral triangle. The vacuum suction cup 2 sucks the flat packaging box at the bottom of the magazine. Under the action of the driving component 3, the turntable 4 rotates, and the turntable 4 drives the mounting rod 5 to rotate simultaneously. When the mounting rod 5 on the turntable 4 rotates to the position of the recognition head 6, the flat packaging box sucked by the vacuum suction cup 2 on the mounting rod 5 faces the recognition head 6 for the recognition head to identify. Then, as the turntable 4 continues to rotate, the mounting rod 5 on the turntable 4 rotates above the conveyor line 1, and the vacuum suction cup 2 on the mounting rod 5 places the sucked flat packaging box on the conveyor line 1.

[0036] Refer to Figures 1 to 3 , Three groove-type photoelectric sensors 12 are fixed on the mounting plate 14, and the three groove-type photoelectric sensors 12 are distributed at the three vertices of an equilateral triangle. Refer to Figure 4 , A ring-shaped detection disk 13 coaxial with it is fixed on the driving disk 7. A notch 131 is formed on the periphery of the detection disk 13. The edge of the detection disk 13 can pass through the U-shaped detection groove of the groove-type photoelectric sensor 12. The groove-type photoelectric sensor 12 is connected to a controller (not shown) through a wire harness, and the controller is electrically connected to the driving component 3 through a wire harness. The controller can be a microcontroller or a single-chip microcomputer, and the controller can control the driving component 3 to work or stop working; when the notch 131 on the detection disk 13 rotates into the U-shaped detection groove of one of the groove-type photoelectric sensors 12, the groove-type photoelectric sensor 12 is triggered and generates a switching signal. The groove-type photoelectric sensor 12 sends the switching signal to the controller, and the controller controls the driving component 3 to pause for a certain period of time (such as 0.5S or 1S) to allow the vacuum suction cup 2 on one mounting rod 5 to suck the flat packaging box at the bottom of the magazine, the flat packaging box sucked by the vacuum suction cup 2 on the second mounting rod 5 to be identified by the recognition head 6 for the barcode, and the vacuum suction cup 2 on the third mounting rod 5 to place the sucked flat packaging box on the conveyor line. Then, the driving component 3 drives the turntable 4 to continue rotating so that the vacuum suction cup 2 sucks the flat packaging box at the bottom of the next magazine, the recognition head 6 identifies the barcode on the next flat packaging box, and the vacuum suction cup 2 places the next flat packaging box on the conveyor line 1. When the notch 131 on the detection disk 13 rotates from the U-shaped detection groove of one groove-type photoelectric sensor 12 to the U-shaped detection groove of the adjacent second groove-type photoelectric sensor 12, the notch 131 rotates 120 degrees, and the turntable 4 also rotates 120 degrees at the same time. One mounting rod 5 just rotates from the material picking position to the recognition position, the second mounting rod 5 just rotates from the recognition position to the separation position (where the vacuum suction cup 2 places the flat packaging box on the conveyor line 1), and the third mounting rod 5 just rotates from the separation position to the material picking position.

[0037] Refer to Figures 1 to 7, in the device of the present invention, the flat packaging boxes 200 stacked together are placed in the bin 100 with an open bottom. The bin 100 is located above the right side of the turntable 4. The surface of the flat packaging box 200 in the bin 100 where the barcode is located faces away from the vacuum suction cup 2. The vacuum suction cup 2 on an installation rod 5 sucks the bottommost flat packaging box 200 in the bin 100. Under the action of the driving component 3, the turntable 4 rotates counterclockwise ( Figure 7 in the A direction in ), the turntable 4 drives the installation rod 5 to rotate simultaneously. At the same time, the installation rod 5 rotates clockwise relative to the turntable 4 on the turntable 4. When the installation rod 5 on the turntable 4 rotates to the position of the recognition head 6, the flat packaging box 200 sucked by the vacuum suction cup 2 on the installation rod 5 faces the recognition head 6 for the recognition head to recognize. Then, as the turntable 4 continues to rotate, the vacuum suction cup 2 on the installation rod 5 on the turntable 4 rotates the sucked flat packaging box 200 above the conveyor line 1, and the vacuum suction cup 2 on the installation rod 5 places the sucked flat packaging box 200 on the conveyor line 1. The turntable 4 continues to rotate, and the installation rod 5 on the turntable 4 rotates to the bin position. The vacuum suction cup 2 on the installation rod 5 sucks the next flat packaging box 200. One rotation of the turntable 4 can complete the processes of taking the flat packaging box 200, barcode recognition, and separation. The vacuum suction cups 2 on the three installation rods 5 can simultaneously and respectively perform taking, barcode recognition, and separation (the vacuum suction cup 2 places the flat packaging box 200 on the conveyor line 1), that is: when the three vacuum suction cups 2 on one installation rod 5 suck the flat packaging box 200 for taking, the flat packaging box 200 sucked by the three vacuum suction cups 2 on the second installation rod 5 faces the recognition head 6 for the recognition head 6 to recognize, and at the same time, the three vacuum suction cups 2 on the third installation rod 5 place the sucked flat packaging box 200 on the conveyor line 1( Figure 7In the state shown, the efficiency of picking up, barcode recognition, and separating the flat packaging box is greatly improved, thereby improving the overall efficiency of the formation of the flat packaging box. At the same time, when the vacuum suction cups 2 on the three mounting rods 5 simultaneously and respectively perform the processes of picking up, barcode recognition, and separating the flat packaging box 200, when the notch 131 on the detection disk 13 rotates into the U-shaped detection groove of one of the groove-shaped photoelectric sensors 12, the driving component 3 pauses for a certain period of time, so that the vacuum suction cup 2 on one mounting rod 5 sucks the bottommost flat packaging box 200 in the bin, the flat packaging box 200 sucked by the vacuum suction cup 2 on the second mounting rod 5 is provided for the recognition head 6 to recognize the barcode, and the vacuum suction cup 2 on the third mounting rod 5 places the sucked flat packaging box 200 on the conveyor line 1. Then, the driving component 3 drives the turntable 4 to continue rotating, so that the vacuum suction cup 2 sucks the bottommost flat packaging box 200 in the next bin 100, the recognition head 6 recognizes the barcode on the next flat packaging box 200, and the vacuum suction cup 2 places the next flat packaging box 200 on the conveyor line 1. In addition, during the process of the vacuum suction cups 2 on the three mounting rods 5 simultaneously and respectively performing the processes of picking up, barcode recognition, and separating the flat packaging box 200, the flat packaging box 200 sucked by the vacuum suction cup 2 will not interfere with the bottom of the bin 100 and the bottommost flat packaging box 200 that has not been sucked in the bin 100, so that the flat packaging box 200 sucked by the vacuum suction cup 2 can be smoothly transferred to the position of the recognition head 6. The flat packaging box 200 sucked by the vacuum suction cup 2 will not interfere with the conveyor line 1 either, so that the flat packaging box 200 sucked by the vacuum suction cup 2 can be smoothly transferred to the conveyor line 1. When the vacuum suction cup 2 is separated from the conveyor line 1, the vacuum suction cup 2 will not interfere with the flat packaging box 200 on the conveyor line 1 either. When the vacuum suction cup 2 rotates to the position of the bin 100 again, the vacuum suction cup 2 will not interfere with the bottom of the bin 100 and the bottommost flat packaging box 200 that has not been sucked in the bin 100, ensuring that the processes of picking up, barcode recognition, and separating the flat packaging box 200 are carried out smoothly and efficiently.
