Description

Technical Field

[0001] This application relates to the field of box blank supply, and more specifically, to a fully automatic box blank loading system. Background Technology

[0002] Cartoning machines often rely on manual feeding, requiring workers to manually cut tape, open cartons, remove box blanks from the cartons, and place them onto the box blank storage rack of the cartoning machine to ensure continuous production. For high-speed cartoning machines, the capacity can typically reach 200-300 boxes per minute, which is extremely labor-intensive for operators. This purely manual feeding method requires workers to frequently bend over and perform large physical movements, which is not only inefficient but also increases the workers' workload. Over time, this poses a risk of occupational diseases and negatively impacts worker health. Summary of the Invention

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this application provides a fully automatic box loading system, including a full-box feeding conveyor 100, a lifting roller platform 200, a box opening device 300, a partition recycling device 400, a pneumatic and vacuum system 500, a robot 600, a box loading fixture 700, a box pushing device 800, an empty box conveying device 900, and a discharge device. The full-box feeding conveyor 100 is installed on the main frame 110 and is used to transport cartons containing box blanks 120. The main frame 110 is also equipped with a protective door for the safety protection of the lifting roller platform 200, the box opening device 300 and the discharge device. The full-box feeding conveyor 100 is a commonly used existing structure, so its specific structure will not be described in detail.

[0027] The lifting roller platform 200 is located at one end of the full-carton feeding conveyor 100. It is used to receive the cartons conveyed by the full-carton feeding conveyor 100 and drive the cartons to move between the conveying position, rejection position, tape-slicing position and opening position arranged at intervals along the height direction. The lifting roller platform 200 is a commonly used existing structure, so its specific structure will not be described in detail.

[0028] like Figure 2As shown, the carton opening device 300 is mounted on the main frame 110 and is used to clamp or release the carton located at the opening position, and to open and fix or release the large pages connected to the top two sides and the small pages connected to the top two ends of the carton.

Each clamping and side-opening cover assembly includes a first guide rail slider 311, a push plate frame 313 connected to one end of the guide rail in the first guide rail slider 311, and push plate cylinders 312 arranged at intervals and connected at both ends to the push plate frame 313 and the corresponding base support 310. The push plate 314 is connected to the corresponding base bracket 310 via a slider seat plate 316 in the first guide rail slider 311. The push plate 314 is connected to the corresponding push plate frame 313, which is connected to a swing mounting plate 318. The swing mounting plate 318 is connected to a swing cylinder 319, which is connected to a side-opening arm 317. Two suction cups 326 are connected to both ends of the side-opening arm 317. The swing cylinders 319 of the two clamping and side-opening assemblies are used to drive the two side-opening arms 317 to cause the corresponding suction cups 326 to adsorb the two large pages of the carton and rotate to open. When the push plate cylinder 312 in the two clamping and side-opening assemblies extends and retracts, it drives the two push plates 314 to move towards or away from each other to clamp or release the sides of the carton. The base bracket 310 is connected to a push plate position detection sensor 315 for detecting the position of the push plate 314.

[0029] Each swing and end-opening assembly includes a swing base 324 rotatable along a vertical axis, an end-opening arm 323 rotatably connected to the swing base 324 along a horizontal axis, and an end-opening cylinder 321 for driving the end-opening arm 323 to rotate. Each end-opening arm 323 is connected to two suction cups 326. When the two end-opening cylinders 321 drive the two end-opening arms 323 to rotate, the corresponding suction cups 326 adsorb the two small pages at both ends of the carton and rotate to open them. The swing base 324 of one of the swing and end-opening assemblies is rotatably connected to the corresponding base bracket 310 along a vertical axis. The carton opening device 300 also includes a sliding adjustment assembly, which includes a second guide rail slider 390 connected to another base bracket 310 and a second guide rail. The slider 390 includes a sliding plate 340, a guide rod 360 connected to the base bracket 310, a locking slider 370 slidably sleeved on the guide rod 360, and a locking handle 380 threadedly connected to the locking slider 370. Two guide rod fixing blocks 350 are connected to the base bracket 310. The two ends of the guide rod 360 are respectively connected to the two guide rod fixing blocks 350. When the locking handle 380 rotates, it fixes or separates the locking slider 370 from the guide rod 360. The locking slider 370 is connected to the slider in the second guide rail slider 390. A limiting ring 328 for limiting the position of the locking slider 370 is fixedly wound around the guide rod 360. The corresponding swing seat 324 of another swing and end-opening cover assembly is rotatably connected to the sliding plate 340 along the vertical axis.

[0030] Both swing and end-opening assemblies include a rotary cylinder 330 and a cylinder seat 320 hinged to the swing base 324 and the cylinder rod of the rotary cylinder 330, respectively. When the rotary cylinder 330 extends or retracts, it drives the corresponding swing base 324 to rotate around the vertical axis through the cylinder seat 320. The two rotary cylinders 330 are respectively connected to the corresponding base bracket 310 and the sliding plate 340. Each swing and end-opening assembly is connected to a push rod assembly. The push rod assembly includes a push rod arm 322 with one end connected to the corresponding swing base 324, two push rod cylinders 327 arranged vertically and spaced apart and connected to the push rod arm 322, and push rods 325 respectively connected to the cylinder rods of the push rod cylinders 327. When each push rod cylinder 327 extends or retracts, it drives each push rod 325 to press against both ends of the carton.

[0031] like Figure 3As shown, the partition recycling device 400 includes an upper box unit frame body 410, a partition recycling bin base 430 connected to the upper box unit frame body 410, four partition recycling bin baffles 420 connected to the partition recycling bin base 430, a safety door 440 connected to the upper box unit frame body 410, a vacuum pump 450, a small stepping platform 460, a robot control cabinet 470, and a robot column 480. The partition recycling bin base 430 and the partition recycling bin baffles 420 enclose a partition recycling bin for accommodating partitions. The pneumatic and vacuum system 500 is connected to the vacuum pump 450, each suction cup, and each cylinder, respectively, for realizing the adsorption and desorption of the suction cups and the extension and retraction of the cylinders. The robot 600 is connected to the robot column 480. The pneumatic and vacuum system 500 and the robot 600 are both existing common structures, and their specific structures are not described in detail.

[0032] like Figure 4 As shown, the upper box clamp 700 is connected to the robot 600. The upper box clamp 700 includes a clamp flange plate 710 connected to the robot 600, a clamp crossbeam plate 730 connected to the clamp flange plate 710 via four clamp connecting rods 720, a cutter fixing frame 750 connected to the bottom of the clamp crossbeam plate 730, a cutter seat 770 connected to the cutter fixing frame 750, a cutter 760 rotatably connected to the cutter seat 770 via a cutter shaft 780, and a cutter cylinder 719 hinged to the cutter 760 via a cutter retraction link 790. The cutter cylinder 719 is connected to the cutter fixing frame 750 via a cylinder seat 711. Two clamping cylinders 716 connect the two ends of the cutter fixing frame 750 to clamping plates 712. When the clamping cylinders 716 extend or retract, they move the two clamping plates 712 closer to or further away from each other to clamp or release the blank 120. Cylinder fine-adjustment sleeves 715 are fitted onto the cylinder rods of the two clamping cylinders 716. A clamping suction cup 713 for adsorbing the blank 120 is connected to both ends of the clamping beam plate 730 via a clamping suction cup plate 714. The cutter fixing frame 750 is connected to vertically arranged suction cup cylinders 718 via a suction cup cylinder connecting plate 717. The suction cup cylinders 718 are used to adsorb or release the partitions. The cutter fixing frame 750 is equipped with vacuum connectors 740 that communicate with the two suction cup cylinders 718 respectively.

[0033] like Figure 5As shown, the box-pushing device 800 is used to receive and transport the box blank 120 falling from above; the box-pushing device 800 includes a box-pushing module bracket 870 for supporting the box blank 120. One side of the box-pushing module bracket 870 is connected to an adjusting stop 840 through an adjusting bracket 830. The other side of the box-pushing module bracket 870 is provided with a side protective cover 860. The adjusting stop 840 is used to limit the box blank 120 on the side of the box-pushing module bracket 870. The adjusting bracket 830 is equipped with an adjusting plate limiting sleeve 820 for switching the position of the adjusting stop 840 to adapt to the positioning adjustment of different types of box blanks 120. The top of the push box module bracket 870 is provided with a push box crossbeam 890 and a push box linear module 880 for driving the push box crossbeam 890 to move along the push box module bracket 870. A cable chain frame 816 and a cable chain 817 are bolted to the top of the push box linear module 880. The cable chain frame 816 connects the cable chain 817 and the push box crossbeam 890 with bolts. The power end of the push box linear module 880 is connected to a push box motor 850 to drive the cable chain 817 to drive the push box crossbeam 890 to reciprocate along the length of the push box module bracket 870. The push box module bracket 870 is also equipped with a control button 810 for controlling the opening and closing of the push box motor 850; the push box crossbeam 890 is fitted with a push box limit sleeve 818 and a sliding push box frame 812, and the push box frame 812 is connected to a push box locking handle 811 by a thread. When the push box locking handle 811 is rotated, it fixes or separates the push box frame 812 from the push box crossbeam 890. The push box frame 812 is fixed with a push box plate 813 by bolts. The push box plate 813 is connected to a retractable top box elastic head 815 and a push box detection sensor 814. When the push box beam 890 moves along the length of the push box module bracket 870, the box blank 120 pushes the top box elastic head 815 to retract into the push box plate 813. At this time, the push box detection sensor 814 is pressed by the top box elastic head 815 and sends a signal to the control system that the push box has been pushed into place. The control system controls the push box motor 850 to stop driving the push box beam 890 to move along the length of the push box module bracket 870 to push the box.

[0034] The empty carton conveyor 900 is used to receive and convey cartons located at the conveying position, and the discharge device 910 is used to receive and convey cartons that have not been properly opened located at the rejection position. Both the empty carton conveyor 900 and the discharge device 910 are existing commonly used structures, and their specific structures are not described in detail.

[0035] The working principle of the fully automatic carton blank loading system provided in this application embodiment is as follows: A full-carton feeding conveyor 100 is used to transport cartons containing carton blanks 120. The lifting roller platform 200 is controlled to receive the cartons transported by the full-carton feeding conveyor 100 and drive the cartons to descend and move to the tape-cutting position. At this time, the cylinder rods of the push plate cylinders 312 of the two clamping and side-opening components of the carton opening device 300 extend to push the sliders in the two first guide rail sliders 311 to move along the guide rail, so that the two push plate frames 313 respectively drive the two push plates 314 to move towards each other to clamp the two sides of the carton. The robot 600 drives the loading clamp 700 to move to the preset position. The cylinder rod of the cutter cylinder 719 of the loading clamp 700 extends to push the cutter 760 around the cutter axis 7 80. Rotate the extended cutter seat 770, thereby using the cutter 760 to cut the tape on the top of the carton held by the two push plates 314 in two horizontal and one vertical directions. Then, control the cylinder rods of the two push plate cylinders 312 to retract, causing the two push plates 314 to move away from each other and stop holding the two sides of the carton. Control the lifting roller platform 200 to drive the carton down to the opening position. Control the cylinder rods of the two push plate cylinders 312 to extend, causing the two push plates 314 to move towards each other and re-clamp the two sides of the carton. Control the swing cylinders 319 of the two clamping and side opening assembly to drive the connected side opening arm 317 to drive the corresponding suction cup 326 to rotate and adsorb the large pages on the top of the two sides of the carton. Then, control the swing cylinders 319 of the two clamping and side opening assembly to drive the connected side opening arm 317 to rotate and adsorb the large pages on the top of the two sides of the carton. The opening arm 317 drives the corresponding suction cup 326 to rotate in the opposite direction, opening and holding the large page. The cylinder rods of the rotary cylinders 330 controlling the two swinging and end-opening components extend, driving the two corresponding swing seats 324 to rotate around the vertical axis. This causes the end-opening arms 323, corresponding suction cups 326, and push rod arms 322, push rod cylinders 327, and push rods 325 connected to the two swing seats 324 to rotate to both ends of the carton. The two end-opening cylinders 321 then drive the two end-opening arms 323 to rotate, causing the corresponding suction cups 326 to pick up the two small pages at both ends of the carton. Subsequently, the two end-opening cylinders 321 drive the two end-opening arms 323 to rotate in the opposite direction, causing the corresponding suction cups 326 to pick up the two small pages at both ends of the carton, opening and holding them. Simultaneously, the push rod cylinders 327 are controlled... The cylinder rod extends, driving the push rods 325 to press and fix both ends of the carton. Then, the robot 600 drives the upper box clamp 700 to extend into the carton and clamp the first layer of box blank 120. The two clamping cylinders 716 of the upper box clamp 700 retract, driving the two clamping plates 712 to move closer together to clamp the first layer of box blank 120. Subsequently, the robot 600 drives the upper box clamp 700 and the clamped first layer of box blank 120 to move above the box pushing module bracket 870 of the box pushing device 800. One side blocks the existing box blanks on the box blank warehouse of the box pushing device 800 to prevent collapse. The box pushing plate 813 automatically retracts and makes room for placement. Then, the system controls the two clamping cylinders 716 of the upper box clamp 700 to extend, driving the two clamping plates 712 to move away from each other.Release the clamped first-layer box blank 120, allowing it to fall onto the box blank storage. The pusher plate 813 returns to the box blank after it has been placed. Then, the robot 600 moves the upper box clamp 700 back into the carton. The cutter fixing frame 750 extends downward through the suction cylinder 718 connected to the suction cylinder connecting plate 717 and suctions the partition between the first and second-layer box blanks 120. Then, the robot 600 moves the partition held by the upper box clamp 700 and the suction cylinder 718 to the partition recycling bin of the partition recycling device 400 and releases it, allowing the partition to be stored in the partition recycling bin. Then, the robot 600 moves the upper box clamp 700 back into the carton and repeats the above steps to move the second-layer box blank 120 onto the box blank storage and drop it. The lifting roller platform 200 is controlled to lift the empty carton and move it to the conveying position. The empty carton conveying device 900 receives and conveys the carton located at the conveying position. The working principle of the box-pushing mechanism is as follows: the box-pushing motor 850 drives the drag chain 817 of the box-pushing linear module 880 to move, which in turn drives the corresponding slider to move the box-pushing beam 890 along the length of the box-pushing module support 870. This cooperates to press the first and second layer box blanks 120 together, and also cooperates with the clamping plate to complete the hand-changing operation.

[0036] If the tape-cutting clamp 700 fails to cut the tape on the top of the carton properly, or if the carton opening position fails to open the carton properly, the lifting roller platform 200 will lift and drive the carton to the rejection position. The discharge device 910 will receive and transport the carton that has not been opened properly at the rejection position, and the staff will handle it.

[0037] In addition, the box opening device 300 also includes a sliding adjustment assembly. The operator can move the sliding plate 340 and its connected swing and end-opening assembly's corresponding swing seat 324 along the guide rod 360 to adjust the position of the corresponding swing seat 324 along the length of the carton. This facilitates the use of the end-opening cylinders 321 connected to the corresponding swing seats 324 of the two swing and end-opening assemblies to drive the two end-opening arms 323 to rotate, causing the corresponding suction cups 326 to adsorb two small pages from the top surface of cartons of different lengths. Simultaneously, the guide rod 360... The guide rod 360 has a locking slider 370 connected to the slider in the second guide rail slider 390 and a locking handle 380 connected to the locking slider 370 by a thread. The operator can rotate the locking handle 380 to fix or separate the locking slider 370 from the guide rod 360 to fix the position of the sliding plate 340 and the corresponding swing seat 324. The guide rod 360 is fixedly wrapped with a limiting ring 328 for limiting the position of the locking slider 370. The limiting ring 328 can be used to limit the position of the locking slider 370, the sliding plate 340 and the corresponding swing seat 324.
