Method for detecting tipping paper splicing section of cigarette making and plug assembling machine, ultrasonic detector and cigarette making and plug assembling machine

Abstract

The embodiment of the invention discloses a method for detecting a tipping paper splicing section of a cigarette making and plug assembling machine, an ultrasonic detector and the cigarette making and plug assembling machine. The method comprises the following steps: transmitting incident ultrasonic waves in preset energy to tipping paper by the ultrasonic detector through a transmitting end when the tipping paper passes through a cigarette replacement splicing support, wherein the incident ultrasonic waves penetrate through transmitting ultrasonic waves behind the tipping paper to come into a receiving end of the ultrasonic detector; converting the received transmitting ultrasonic wave energy into a corresponding electric quantity value by the ultrasonic detector through the receiving end, and comparing whether the converted electric quantity value is less than a preset electric quantity value; if the converted electric quantity value is less than the preset electric quantity value, judging that the tipping paper contains a splicing section through the receiving end of the ultrasonic detector, and transmitting a high level signal to a controller by the ultrasonic detector through an output end; and if the converted electric quantity value is equal to the preset electric quantity value, judging that the tipping paper does not contain the splicing section by the receiving end of the ultrasonic detector. According to the embodiment of the invention, the accuracy of the detection result of the tipping paper splicing section can be improved.

Description

technical field [0001] The invention relates to detection technology, in particular to a detection method for a splicing section of tipping paper of a splicing machine, an ultrasonic detector and a splicing machine. Background technique [0002] Tipping paper is one of the auxiliary materials necessary for the production of the splicing machine. In daily production, the splicing section detector that comes with the cigarette machine needs to detect two kinds of splicing sections. The first is the splicing section that exists in the process of manufacturing tipping paper; the second is the splicing section that exists in the production of tipping machine. The splicing segment formed by automatic splicing of paper. At present, the PROTOS70 coiling machine in cigarette manufacturing is equipped with a tipping paper splicing section detector, which adopts the photoelectric detection mode and consists of two parts: photodetector PG10 and amplifier PG11. Its working principle is...

Problems solved by technology

[0003] However, with the improvement of the production process of tipping paper and the diversification of the appearance of cigarettes, the detection method of the above-mentioned tipping paper splicing section can no longer meet the current requirements, and the following problems will occur in the detection process of the detector: first, if the water The loose paper has a variety of colors, and the detector will output high level by mistake, and reject good cigarettes at the cigarette cutting drum, resulting in increased product consumption; second, if the tipping paper has no "warped edge" stitching segment, that is, the splicing segment formed by smooth bonding, the reflected light received by the receiving end does not change, and the detector cannot output a high level. At this time, the detector mistakenly detects that the tipping paper has no splicing segment, so The paper device will not move, but because the edges and corners of the scraper have been acting on the tipping paper, the tipping paper in the splicing section will break, resulting in a shutdown phenomenon, resulting in a high shutdown rate of the equipment and a low effective operation rate
