Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of tobacco packaging auxiliary machinery, and particularly relates to a placing and protecting follow-up device for a side-opening hard carton and a pushing method. BACKGROUND

[0002] At present, hard carton feeding is mostly carried out manually. Workers take out prefabricated side-opening cartons one by one according to the operation of the machine, stack them neatly on the conveying belt of the filling machine in a specific way, and ensure that the front bottom surface of each hard carton is in the correct posture and faces left or right. Since there is no follow-up protection, the carton stack needs to be ensured not to tip over or shift position when the conveying belt of the filling machine is moving. When the tobacco packaging machine is not running at high speed and the production capacity is not high, 1-2 workers need to continuously feed the machine, which can meet the production demand. Once the packaging machine runs too fast or the manual filling is interrupted, the entire machine group will be shut down due to lack of materials.

[0003] The traditional hard carton feeding method requires 1-2 workers to continuously feed on site, which is low in efficiency, high in labor intensity, and messy on site. In the on-site work, it is found that there are errors such as left-right reverse stacking and right-left reverse stacking in the whole stack, which are easily ignored by workers and seriously affect the efficiency of the next automatic packaging. At the same time, the hard carton feeding speed needs to match the feeding speed of the main machine. Manual feeding may cause problems such as late feeding, heavy workload, large feeding position error, and equipment shutdown. In addition, the quantity of hard carton feeding mainly relies on the record of the post worker, which is time-consuming and inaccurate. Moreover, the learning and use cost of manual feeding is also high. The manual hard carton feeding method has restricted the automation and intelligentization of the tobacco packaging machine group. SUMMARY
