[0036] The present invention also provides an automatic box feeding and stacking method, which uses the above-mentioned automatic box feeding and stacking device. The method includes the following steps:

[0037] S1: The device is initially in the automatic box supply mode. The control box controls the first stepping motor and the second stepping motor to drive the laser distance sensor on the clamping mechanism to move up and down and left and right. The laser distance sensor feeds back the position information of the empty cigarette box to the control box. After the control box performs logical calculations, it controls the first stepping motor and the second stepping motor to drive the clamping mechanism to move so that the suction cup aligns with the empty cigarette box.

[0038] S2: The cylinder shaft in the cylinder mechanism extends, making the suction cup contact the empty cigarette box.

[0039] S3: The control box controls the first stepping motor to work, driving the clamping mechanism to clamp the empty cigarette box and move it to the packing platform to the left.

The control box controls the first solenoid valve to be energized, and the rotary cylinder works to drive the cylinder mechanism and the clamping mechanism to rotate clockwise by 90 degrees. The control box controls the first stepping motor to work, driving the clamping device to retract to the right and clamp the next empty cigarette box to the packing platform.

[0040] S4: When the worker loads the cigarette bars into the empty cigarette box, the empty cigarette box becomes a finished cigarette box. Press the cigarette box stacking control button to switch to the cigarette box stacking mode. The control box controls the first stepping motor to drive the clamping mechanism to move in front of the packing platform. The cylinder shaft of the cylinder mechanism extends, making the suction cup contact the finished cigarette box. The control box controls the second solenoid valve to be energized, and the micro cylinder and the suction cup are connected to the negative pressure air suction source. The micro cylinder drives the movable jaw to clamp the finished cigarette box, and the suction cup sucks the finished cigarette box.

[0041] S5: When the clamping mechanism clamps the finished cigarette box, the weight sensor detects the weight of the finished cigarette box and transmits the weight information to the control box for comparison with the weight preset value to determine whether the finished cigarette box is missing cigarette bars. If the finished cigarette box is determined not to be missing cigarette bars, the first solenoid valve is energized, and the rotary cylinder works to drive the cylinder mechanism and the clamping mechanism to drive the finished cigarette box to rotate clockwise by 180 degrees. The control box controls the first stepping motor and the second stepping motor to drive the clamping mechanism to stack the finished cigarette box on the finished cigarette box tray. After the finished cigarette box is stacked, the device automatically switches to the automatic box supply mode. If the finished cigarette box is determined to be missing cigarette bars, the second solenoid valve is de-energized, and the micro cylinder and the suction cup stop working. The clamping mechanism releases the missing cigarette box and it falls on the packing platform. The alarm device issues an alarm to prompt the worker to handle it. After the handling is completed, the worker presses the reset button, and the device resumes to the automatic box supply mode.

8. An automatic box feeding and stacking method, which uses the automatic box feeding and stacking device according to any one of claims 1-7, characterized in that, The method includes the following steps: S1: The device is initially in the automatic box supply mode. The control box (8) controls the first stepping motor (12) and the second stepping motor (15) to drive the laser distance sensor (28) on the clamping mechanism (5) to move up and down and left and right. The laser distance sensor (28) feeds back the position information of the empty cigarette box (31) to the control box (8). After the control box (8) performs logical calculations, it controls the first stepping motor (12) and the second stepping motor (15) to drive the clamping mechanism (5) to move so that the suction cup (25) aligns with the empty cigarette box (31). S2: The cylinder shaft in the cylinder mechanism (4) extends, so that the suction cup (25) contacts the empty cigarette box (31). The control box (8) controls the second solenoid valve (26) to be energized, and the micro cylinder (24) and the suction cup (25) are connected to the negative pressure suction air source. The micro cylinder (24) drives the movable jaw (23) to clamp the empty cigarette box (31), and the suction cup (25) sucks the empty cigarette box (31). S3: The control box (8) controls the first stepping motor (12) to work, driving the clamping mechanism (5) to clamp the empty cigarette box (31) and move it to the packing platform (6) to the left. The control box (8) controls the second solenoid valve (26) to be de-energized, so that the movable jaw (23) and the suction cup (25) release the empty cigarette box (31) and it falls onto the packing platform (6). The control box (8) controls the first solenoid valve (20) to be energized, and the rotary cylinder (19) works to drive the cylinder mechanism (4) and the clamping mechanism (5) to rotate clockwise by 90 degrees. The control box (8) controls the first stepping motor (12) to work, driving the clamping mechanism (5) to retract to the right and clamp the next empty cigarette box (31) to the packing platform (6). S4: After the worker loads the cigarette bars into the empty cigarette box (31), the empty cigarette box (31) becomes a finished cigarette box (32). Press the cigarette box stacking control button (7) to switch to the cigarette box stacking mode. The control box (8) controls the first stepping motor (12) to drive the clamping mechanism (5) to move in front of the packing platform (6). The cylinder shaft of the cylinder mechanism (4) extends, so that the suction cup (25) contacts the finished cigarette box (32). The control box (8) controls the second solenoid valve (26) to be energized, and the micro cylinder (24) and the suction cup (25) are connected to the negative pressure suction air source. The micro cylinder (24) drives the movable jaw (23) to clamp the finished cigarette box (32), and the suction cup (25) sucks the finished cigarette box (32). S5: When the clamping mechanism (5) clamps the finished cigarette carton (32), the weight of the finished cigarette carton (32) is detected by the gravity sensor (27) and the weight information is transmitted to the control box (8) for comparison with the preset weight value to determine whether there is a missing cigarette in the finished cigarette carton (32). If the finished cigarette carton (32) is determined not to be a missing-cigarette carton, the first solenoid valve (20) is energized, the rotary cylinder (19) works to drive the cylinder mechanism (4) and the clamping mechanism (5) to drive the finished cigarette carton (32) to rotate clockwise by 180 degrees. The control box (8) controls the first stepping motor (12) and the second stepping motor (15) to drive the clamping mechanism (5) to stack the finished cigarette carton (32) onto the finished cigarette carton tray. After the finished cigarette carton (32) is stacked, the device automatically switches to the automatic carton supply mode. If the finished cigarette carton (32) is determined to be a missing-cigarette carton, the second solenoid valve (26) is de-energized, the micro cylinder (24) and the suction cup (25) stop working, the clamping mechanism (5) releases the missing-cigarette carton and it falls onto the packing platform (6), and the alarm device (29) gives an alarm to prompt the staff to handle it. After the handling is completed, the staff presses the reset button (30), and the device resumes to the automatic carton supply mode.
