Inner frame paper fixed length conveying system and method

Abstract

The invention relates to the technical field of cigarette packaging, in particular to an inner frame paper fixed length conveying system. The inner frame paper fixed length conveying system is arranged on a cigarette packaging machine, and comprises a servo driving mechanism, a detector, an encoder and a controller; the servo driving mechanism is connected with a conveying roller for conveying inner frame paper and drives the conveying roller to rotate; the detector is used for detecting color codes on the inner frame paper, and the encoder is used for acquiring a main engine phase position ofthe cigarette packaging machine; and the servo driving mechanism, the detector and the encoder are all connected with the controller. The invention further relates to an inner frame paper fixed length conveying method adopting the inner frame paper fixed length conveying system. Mainly the controller determines a reference position according to an action signal of the encoder and a first color code position signal detected by the detector, and zero searching operation is completed; and the controller controls the rotating speed at which the servo driving mechanism drives the conveying rollerto rotate according to a deviation value between the color code position signal detected by the detector and a reference position, so that the conveying speed of the inner frame paper meets the fixedlength conveying requirement. High-precision fixed length conveying can be achieved.

Description

technical field [0001] The invention relates to the technical field of cigarette packaging, in particular to a fixed-length conveying system and method for inner frame paper. Background technique [0002] In the existing hard box and hard rod cigarette packaging machine, the inner frame paper is conveyed by mechanical transmission, and through the cooperation of various cam structures, the inner frame paper conveying roller is synchronized with the speed of the main machine to convey the inner frame paper . With this conveying method, the conveying length of the inner frame paper can be fixed, but if the length specification of the inner frame paper is to be changed, the cam needs to be redesigned to match. Moreover, with the emergence of pre-printed inner frame paper in many cigarette factories, another disadvantage of this delivery method has also been exposed-although it can be delivered to a fixed length, it cannot deliver inner frame paper according to printing require...
