Description

Technical Field

[0001] This invention relates to the field of cigarette equipment technology, and more specifically, to a tobacco carton folding and palletizing machine. Background Technology

[0002] Currently, the carton folding and palletizing machine on the unpacking line in the cigarette manufacturing workshop automatically stacks the empty cartons removed by the unpacking machine after folding them. During production, a carton trolley pulls the neatly folded cigarette cartons to a designated position. Upon detecting a signal from a magnetic switch, the clamping mechanism releases, and the trolley continues moving forward, causing the cartons to automatically fall onto the palletizer. The palletizer automatically adjusts its height via a photoelectric switch to prepare for subsequent carton placement. However, the carton palletizing machine has the following problems in actual use: After the carton reaches the unloading position and the clamping mechanism releases, due to inertia, the carton does not immediately fall off the trolley but continues to move forward a distance before falling onto the palletizer without a fixed position, resulting in messy and disorderly carton stacking. Sometimes, the cartons not falling off can damage the equipment and the cartons, reducing the effective operating rate of the equipment. To avoid this, during production, dedicated personnel must manually stack the cigarette cartons on the palletizer, which increases labor costs and labor intensity.

[0053] Specific working principle: During production, empty cartons are conveyed to the flipping device 2 platform by the previous stage equipment. The two-position three-way valve forward reversing controls the folding device 3 to extend into position, folding the cartons. After folding, the flipping motor 5 drives the flipping device 2 to flip forward. Once the first detection photoelectric sensor 6 detects that the flipping is in place, the flipping motor 5 stops running. When the carton-pulling device 12 is waiting to work, it is located at the first magnetic switch 8. When the clamping device 14 is waiting to work, it is in the open state. After the first detection photoelectric sensor 6 detects that the flipping device 2 is in place, the clamping device 14 controls the air exchange of the second two-position three-way valve 15 to clamp the cartons. After clamping, the carton-pulling device 12 controls the forward air exchange of the first two-position three-way valve 7 to move from point B to point A. When the first detection photoelectric sensor 6 no longer detects the cartons, the flipping motor 5 drives the flipping device 2 to flip in the reverse direction. After flipping to the starting position, the folding device 3... The two-position three-way valve reverses the air exchange control to retract the carton into position, waiting for the next operation. When the carton-pulling device 12 moves to the second magnetic switch 11, the clamping device releases it through the air exchange control of the second two-position three-way valve 15. At this time, the baffle device 9 blocks the carton, and the carton falls onto the roller conveyor 20 platform for stacking. When the carton-pulling device 12 continues to run to the third magnetic switch 13, the first two-position three-way valve 7 reverses the air exchange control to move it from point A to point B. When it moves to the first magnetic switch 8, it stops running and waits for the arrival of the next folded carton. During the carton palletizing process, the roller conveyor 20 starts at the first limit photoelectric sensor 17. When the second detection photoelectric sensor 16 detects a cigarette box on the roller conveyor 20 platform, it controls the lifting motor to run in reverse, causing the roller conveyor 20 to descend one step. When the roller conveyor 20 descends to the second limit photoelectric sensor 18, it stops descending. At this time, the roller conveyor 20 transports the palletized cigarette box to the next process. The roller conveyor 20 rises to the first limit photoelectric sensor 17 and continues to wait for palletizing.

[0054] The baffle device 9 is an auxiliary unloading device. When the carton-pulling device 12 pulls the carton to the second magnetic switch 11, the clamping device 14 releases. At this time, the stainless steel tube 27 in the auxiliary unloading device blocks the carton. The carton-pulling device 12 continues to move in direction A to the limit position of the third magnetic switch 13. Because the stainless steel tube 27 blocks the carton at the same position each time, each carton will fall from the same position for neat stacking. The second support arm 25 acts as a buffer for the carton, preventing damage to the equipment due to malfunction of the clamping mechanism not releasing or not fully releasing. The spring 30 returns the second support arm 25 to its original position after each operation. The baffle 24 ensures that the second support arm 25 returns to the same position after each operation.

[0055] In summary, the technical content disclosed in this invention improves the intelligence level of equipment, saves labor costs, increases the effective operating rate of equipment, reduces the intensity of manual labor, makes cardboard boxes stacked more neatly, and reduces or avoids damage to cardboard boxes.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention.
