Paper box opening method and opening system thereof

Abstract

Disclosed are a carton opening method and the package opening system. The method uses a cover-opening device to open an inner carton cover where the inner carton and the outer carton are nested together; after the carton is overturned 180 degrees by a carton-overturning device, a carton-removing device will cling to the outer carton wall and meanwhile clamp the inner carton cover for uplifting, so that the outer carton driven by the inner carton cover will be vertically lifted together with the inner carton cover to be separated from the items in the carton, and the empty carton will be folded and stacked. The system comprises a transportation device (5), a carton-overturning device (10), a carton-removing device (12) and a carton folding and stacking device (15) that are sequentially arranged along the carton transportation direction; a carton-opening device (6) is arranged beside the transportation device (5). The present invention has good self-adaptive ability to meet certain sized and open seriously damaged or deformed cigarette packages, which is of good effect and reliability and will neither damage cartons, nor easily break the materials.

Description

technical field [0001] The invention relates to an automatic production system in the tobacco industry, which automatically separates the packaging carton of the carton sheet cigarette package from the tobacco base, and folds and stacks the empty carton for output. Background technique [0002] In modern cigarette production enterprises, a large number of raw tobacco leaves have been threshed and rebaked and packaged into certain specifications of laminar cigarette bales. There is a lower box cover, which is called the inner box cover; the outer box has an upper box cover, which is called the outer box cover. The inner box cover and the outer box cover respectively cover the bottom surface and the top surface of the cigarette pack. After the packaged cartons are transported and stored for a long time, most of the cartons will be deformed and partially damaged, which is not conducive to the use of mechanized means for automatic unpacking and recycling of empty cartons. The ...

AI Technical Summary

Problems solved by technology

After the packaged cartons are transported and stored for a long time, most of the cartons will be deformed and partially damaged, which is not conducive to the use of mechanized means for automatic unpacking and recycling of empty cartons

The existing carton unpacking system, such as the technology disclosed in Chinese patent CN1463894A, has a good effect of separating the carton from the tobacco base, but it is easy to damage the carton, which is not conducive to the recycling of empty cartons, causing unnecessary damage to cigarette manufacturers. Another kind of technology disclosed in Chinese patent CN1623858 is not easy to damage the cartons, which is beneficial to the recycling of empty cartons, but the effect of separating the cartons from the tobacco blanks is not ideal, and it is difficult to deal with large and dilapidated cartons. Not conducive to improving the degree of automation of production

In addition, the tobacco blanks in some cigarette packs are covered with plastic packaging films, and the existing carton unpacking systems cannot automatically remove the plastic packaging films on the tobacco blanks
