Description

Technical Field

[0001] The present invention relates to the field of intelligent cigarette manufacturing, and in particular to a cigarette carton disassembling device and a method thereof. Background Art

[0002] With the development of the tobacco industry, the quality of cigarette cartons, cigarette packs, and cigarette sticks sold directly to consumers has become a key to controlling the quality of finished cigarettes by cigarette manufacturers; in order to ensure the quality of finished cigarettes, before leaving the factory, it is generally necessary to take out the normally produced products from the cigarette finished product warehouse and then send them to the laboratory for a series of tests. However, since cigarettes are usually fully packaged cigarettes after normal production, they need to be disassembled again. For example, when testing the quality of cigarette packaging, the carton outside the cigarette cartons needs to be removed before further operation. Due to the lack of special equipment, this disassembly process often relies on manual operation, and the operation process is generally: first remove the carton packaging film through the pull line on the carton, and then open the carton to take out the cigarette pack. In this process, a common problem is that the carton surface film is a transparent film with a relatively thin thickness, so it is often easy to have the disadvantage of the transparent film being difficult to remove. In addition, there are glue spots on the carton and the paper edges are sharp, so it is easy to scratch people when operating carelessly. Therefore, overall, this manual disassembly method is relatively inefficient, and the rate of picking out defective products is greatly affected by human factors, the effect is not ideal, and the progress of related testing work is affected.

[0003] In order to reduce the quality defect rate of cigarette cartons, each cigarette factory is currently equipped with some quality inspection devices to ensure the quality of finished cigarettes. On the packaging machine, there are cigarette carton wire detection devices, cigarette carton missing package detection devices or cigarette carton appearance detection devices, etc. These quality inspection devices detect some cigarette cartons with quality defects. For these cigarette cartons with quality defects, some cigarette factories will directly treat them as waste cigarettes because they are difficult to disassemble and the cost of manual disassembly is high, which is very wasteful.

[0004] In summary, the manual quality inspection of cigarette cartons has the following shortcomings: unstable quality inspection, low inspection rate, frequent missed inspections; high labor and production costs; increased difficulty in managing manual work departments with concentrated personnel; difficult to achieve standardized management; and not in line with the current trend of intelligent manufacturing.
