[0066] The present invention provides an intelligent integrated system for loading and unloading cartons, which unloads cartons through the following steps, and the method includes:

[0067] Step 1: The universal mechanical arm 12 in the robot box feeding assembly 10 rotates to drive the box suction clamp 13 to move back and forth between the bundled cardboard raw materials and the box stacking and cutting and feeding assembly 20 to transport the bundled cardboard;

[0068] Step 2: The box pusher and retractor assembly 23 pushes the cardboard to facilitate the cutting assembly 22 to cut the strapping tape. After the cutting assembly 22 cuts the strapping tape, the box pusher and retractor assembly 23 recycles the strapping tape, and a plurality of cardboard stacks with the strapping tape cut fall onto the descending mechanism 25:

[0069] Step 3: The descending mechanism 25 places a plurality of stacks of cardboards with cut straps on the feeding conveyor belt 26, and the feeding conveyor belt 26 conveys them to the suction box feeding assembly 40;

[0070] Step 4: The lifting mechanism 44 is lifted as the number of the stacked single cardboards decreases, and the box suction mechanism 42 sucks the single cardboards in turn and drives the cardboards to move toward the feeding roller 43, and the feeding roller 43 rotates to transport the single cardboards evenly to the unpacking transmission line 32;

[0071] Step 5: The unpacking transmission line 32 drives the unpacked cardboard to move in turn, the lower suction cup 33 and the upper suction cup 331 respectively adsorb one side of the cardboard, the upper suction cup 331 rotates to open the carton, the folding mechanism 34 folds and closes the opened carton, and the sealing mechanism 35 seals the folded and closed carton.

[0072] The present invention provides an intelligent integrated system for loading and unloading boxes. Figure 1 , Figure 2As shown, first, the box suction clamp 13 rotates relative to the output end of the universal robot arm 12 so that the strapping belt of the bundled cartons is perpendicular to the material clamp arm 15, and at the same time, the universal robot arm 12 rotates to drive the box suction clamp 13 to the raw materials of several bundled cartons, and the clamp arm driving mechanism 151 drives the material clamp arm 15 to extend relative to the clamp frame 14 so that the clamp suction cup 17 can absorb the materials of the bundled cartons; after the clamp suction cup 17 absorbs the materials of the bundled cartons, the clamp arm driving mechanism 151 drives the material clamp arm 15 to retract relative to the clamp frame 14, and at the same time, the pressure plate driving mechanism 161 drives the clamp suction cup pressure plate 16 to press the materials of the bundled cartons so that they are stable during the movement, and the clamp suction cup 17 stops sucking the bundled cardboard.

[0073] Next, the universal robot arm 12 rotates and drives the box suction clamp 13 that has sucked the bundle of cardboard to the box stacking and cutting and feeding assembly 20, and the cardboard unloading driving mechanism 241 drives the cardboard unloading plate 24 to extend relatively to the pushing and cutting assembly 22 and the box pushing and retracting assembly 23 to support the bundle of cardboard. The clamping arm driving mechanism 151 drives the material clamping arm 15 to extend relative to the clamp frame 14 again to place the bundle of cardboard on the cardboard unloading plate 24, and then the universal robot arm 12 continues to rotate and drives the box suction clamp 13 to the raw material of the bundle of cardboard boxes to suck the material.

[0074] Then, if Figures 3 to 11 As shown, the push box driving mechanism drives the push box support block 239 to move longitudinally along the y-axis, and the push box support block 239 extends out the push cardboard relative to the push box bottom plate 231 to leave space for the blade 222 to cut the strapping tape; then, the blade driving mechanism 223 drives the blade 222 to move horizontally along the x-axis or in the opposite direction of the x-axis to cut the strapping tape; after the cutting is completed, the push box driving mechanism drives the push box support block 239 to move longitudinally in the opposite direction of the y-axis, and the push box support block 239 retracts relative to the push box bottom plate 231, and at the same time, the pull rope driving mechanism 233 drives the two pull rope clamps 232 to move toward each other along the x-axis and in the opposite direction of the x-axis to clamp the strapping tape.

[0075] Afterwards, the retraction longitudinal drive mechanism 234 drives the rope drive mechanism 233 to move along the opposite direction of the y-axis to the recovery roller, driving the rope clamp 232 to clamp the cut strapping belt and move it to the retraction roller, and the rope clamp 232 moves in opposite directions to loosen the strapping belt; then, the roller drive mechanism 238 drives the active roller 236 to rotate, driving the passive roller 237 to rotate, and the guide plate drive mechanism 27 drives the guide plate 271 to move downward along the opposite direction of the z-axis, and the guide plate 271 guides the strapping belt to the active roller 236 and the passive roller 237, so as to facilitate the recovery roller to rotate and recycle the strapping belt, and the strapping belt is recovered into the drawer of the recovery box 235 as the active roller 236 and the passive roller 237 rotate.

[0076] Next, the cardboard unloading driving mechanism 241 drives the cardboard unloading plate 24 to move along the y-axis and in the opposite direction of the y-axis, and the cardboard unloading plate 24 retracts relative to the pushing and cutting component 22 and the pushing and box retracting component 23, and the stack of cardboards with the cut strapping bands falls onto the descending mechanism 25, and the descending driving mechanism 253 drives the lower square tube 252 to move on the descending guide column 251 to buffer the stack of cardboards with the cut strapping bands.

[0077] When a certain number of pieces are cached, the descending driving mechanism 253 continues to drive the descending square tube 252 to move in the opposite direction along the z-axis on the descending guide column 251 until the descending square tube 252 is parallel to the feeding conveyor belt 26, and several stacks of single cardboards are stacked on the feeding conveyor belt 26. Several stacks of single cardboards are moved along the x-axis direction to the suction box feeding assembly 40 through the feeding conveyor belt 26.

[0078] The initial position of the lifting square tube 442 is parallel to the feeding conveyor belt 26. When a number of stacks of cardboards with cut straps are located above the lifting square tube 442, the lifting drive mechanism 443 drives the lifting square tube 442 to rise on the lifting slide rail 441 along the z-axis direction, driving the stacks of cardboards with cut straps to rise to the feeding suction cup 422; then, the suction box drive mechanism 426 drives the telescopic rod 427 to extend, driving the feeding suction cup 422 to move in the opposite direction of the z-axis. After the feeding suction cup 422 absorbs a single piece of cardboard, the suction box drive mechanism 426 drives the telescopic rod 427 to retract, driving the feeding suction cup 422 to move along the z-axis so that the absorbed single piece of cardboard is between the two feeding rollers 43.

[0079] Then, the feeding drive mechanism 425 drives the suction cup slide 421 to reciprocate along the x-axis and the opposite direction of the x-axis on the suction cup slide rail. The suction cup slide 421 moves along the x-axis direction, driving the feeding suction cup 422 that has adsorbed a single piece of cardboard to move, and feeds the cardboard onto the two feeding rollers 43. The two feeding rollers 43 arranged in parallel rotate to facilitate the cardboard to be smoothly fed into the unpacking component 30; then, the suction cup slide 421 moves in the opposite direction of the x-axis, driving the feeding suction cup 422 to return to the top of the lifting mechanism to continue to absorb the single piece of cardboard.

[0080] Then, the feeding drive mechanism 425 drives the suction cup slide 421 to move along the x-axis direction on the suction cup slide rail, driving the feeding suction cup 422 that has adsorbed a single piece of cardboard to move, and feeding the cardboard between the two feeding rollers 43. The two feeding rollers 43 arranged in parallel rotate to facilitate the cardboard to be smoothly fed into the unpacking component 30. The lifting drive mechanism 443 drives the lifting square tube 442 to lift as the number of stacked single pieces of cardboard decreases. The suction box driving mechanism 426 drives the feeding suction cup 422 to reciprocate along the z-axis and the opposite direction of the z-axis to absorb the single piece of cardboard. The feeding drive mechanism 425 drives the suction cup slide 421 to reciprocate along the x-axis and the opposite direction of the x-axis on the suction cup slide rail, and feeds the cardboard to be unpacked into the feeding roller 43. The feeding roller 43 rotates to facilitate the cardboard to be smoothly fed into the unpacking component 30.

[0081] like Figures 12 to 15 As shown, the cardboard coming out of the feeding roller 43 falls onto the unpacking transmission line 32 in sequence, and the unpacking transmission line 32 drives the unpacked cardboard to move along the x-axis direction in sequence. When passing through the lower suction cup 33, the lower suction cup 33 and the upper suction cup 331 respectively adsorb one side of the cardboard, and then the suction box rocker arm driving mechanism 335 drives the suction box rocker arm 334 to rotate, driving the suction box rotating rod 333 to rotate, and the upper suction cup 331 adsorbs one side of the cardboard as the suction box rotating rod 333 rotates to open the carton.

[0082] After the carton is opened, the front cover folding rocker arm driving mechanism drives the front cover folding rocker arm 345 to rotate, driving the front cover folding plate 341 to rotate and close the front cover of the carton, and the rear cover folding rod driving mechanism drives the rear cover folding rod to rotate, driving the rear cover folding plate 342 to rotate and close the rear cover of the carton; then, the upper cover folding cylinder driving mechanism drives the upper cover folding cylinder 346 to rotate, driving the upper cover folding plate 343 to rotate and close the upper cover of the carton, and the lower cover rocker arm driving mechanism drives the lower cover rocker arm to rotate, driving the lower cover folding plate 344 to close the lower cover of the carton; then, the unpacked cartons continue to move along the x-axis along the unpacking transmission line 32 in sequence, and after the sealing tape 351 is attached to the upper and lower covers of the sealed carton, the tape cutter 352 cuts off the excess tape, and the tape pressing guide wheel 353 rolls on the sealed carton to compress the sealing tape.

[0083] Compared with the prior art, the present invention provides an intelligent integrated box loading and unpacking system, in which a robot box feeding component is arranged to deliver the bundled cardboard raw materials to the box stacking and cutting and feeding component, which cuts and recycles the strapping tapes of the bundled cardboards, and caches the stacked cardboards with the strapping tapes cut, and then successively absorbs the single pieces of cardboards and smoothly delivers them to the box unpacking component, which successively unpacks and seals the single pieces of cardboards; the present invention provides a robot box unpacking machine, which takes materials from the bundled cardboard raw materials to the box unpacking machine, and successively unpacks and seals the single pieces of cardboards, without any manual intervention in the whole process, thereby reducing the labor intensity and improving the production efficiency.
