The feeding roller 43 rotates to transport the single cardboards smoothly to the next process.

[0080] The present invention provides a carton loading machine for unpacking cartons. When the carton is actually being loaded, Figure 1 , Figure 2 As shown, first, the box delivery 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 delivery 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 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 absorbing the bundled cardboard.

[0081] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, then, the universal robot arm 12 rotates to drive the box feeding clamp 13 that has sucked the bundle of cardboard to the box stacking assembly 20, and the cardboard unloading driving mechanism 241 drives the cardboard unloading plate 24 to extend relative to the pushing and cutting assembly 22 and the box pushing and retracting assembly 23 to support the bundle of cardboard, and 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 materials on the cardboard unloading plate 24, and then the universal robot arm 12 continues to rotate to drive the box feeding clamp 13 to the raw material of the bundle of cardboard boxes to suck the material.

[0082] like Figures 3 to 6As shown, the push box driving mechanism then drives the push box support block 239 to move longitudinally along the y-axis, and the push box support block 239 extends 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 laterally 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.

[0083] like Figures 3 to 6 As shown, after that, 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 block 232 to clamp the cut strapping belt and move it to the retraction roller, and the rope clamp block 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 26 drives the guide plate 261 to move downward along the opposite direction of the z-axis, and the guide plate 261 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.

[0084] like Figures 3 to 7 As shown, then, the cardboard unloading driving mechanism 241 drives the cardboard unloading plate 24 to move along the y-axis and the opposite direction of the y-axis, the cardboard unloading plate 24 retracts relative to the pushing and cutting component 22 and the pushing and box retracting component 23, and the stacks of cardboards with the cut strapping bands fall onto the descending mechanism 25, and the descending driving mechanism 253 drives the descending square tube 252 to move on the descending guide column 251 to buffer the stacks of cardboards with the cut strapping bands.

[0085] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, 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 conveying belt 30, and several stacks of single-piece cardboard are stacked on the conveying belt 30. Several stacks of single-piece cardboard are moved along the x-axis direction to the suction box feeding assembly 40 through the conveying belt 30.

[0086] like Figure 1 , Figure 8 , Fig. 9 , Fig.10 , Fig.11As shown, the initial position of the lifting square tube 442 is parallel to the conveyor belt 30. 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.

[0087] like Figures 8 to 10 As shown, 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, and the suction cup slide 421 moves along the x-axis direction, driving the feeding suction cup 422 that has absorbed a single piece of cardboard to move, and feeds the cardboard onto the two feeding rollers 43, and the two feeding rollers 43 arranged in parallel rotate to facilitate the cardboard to be smoothly fed into the next process; 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.

[0088] like Figures 8 to 10 As shown, the feeding drive mechanism 425 then 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 two feeding rollers 43. The two feeding rollers 43 arranged in parallel rotate to facilitate the cardboard to be smoothly fed into the next process.

[0089] like Figures 8 to 10 As shown, the lifting drive mechanism 443 drives the lifting square tube 442 to lift as the number of stacked single cardboards 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 cardboard, and the feeding drive mechanism 425 drives the suction cup slide plate 421 to reciprocate along the x-axis and the opposite direction of the x-axis on the suction cup slide rail to feed the cardboard to be unpacked into the feeding roller 43, and the feeding roller 43 rotates to facilitate the cardboard to be smoothly fed into the next process.

[0090] Compared with the prior art, the present invention provides an automatic carton loading machine for unpacking cartons. A robot carton feeding component transports the bundled cardboard raw materials to a box stacking component. The box stacking component cuts the bundled cardboard and recycles the strapping tape. Several cardboards with cut strapping tapes are stacked and transported to a suction box feeding component through a conveyor belt. The suction box feeding component sucks and flattens a single piece of cardboard into the next process. No manual intervention is required throughout the process, which reduces manual labor and improves production efficiency.
