Description

A pipe photoelectric signal detection device at the output end of a cigarette filter rod transmitter

technical field

The utility model relates to the technical field of tobacco processing and detection, in particular to a pipe photoelectric signal detection device at the output end of a cigarette filter rod transmitter.

Background technique

In the production process of cigarette enterprises, the filter rods used in cigarette equipment (referred to as the rods for short) are generally conveyed by the method of "air delivery", that is, in the same factory area, the rod transmitters are powered by wind (compressed air), through A closed delivery duct transports the rods to the receiving station on the cigarette making machine.

The specific method is as follows: the mouth stick transmitter and the mouth stick receiving station on the cigarette equipment are connected by one (or more) pipelines, and the distance between the two places is generally between 30-400 meters. The mouth stick is output by the mouth stick transmitter. There is a launch wheel under the hopper of the mouth stick transmitter. There are grooves with suction holes on the outer circle of the launch wheel. There is a sealing block under the launch wheel, which cooperates with the launch wheel. A sealed chamber is formed. When working, the nozzle rods in the hopper fall into the grooves of the launching wheel respectively and are sucked by the suction. When the rotating launching wheel sends the nozzle rods into the launching station, the suction of the suction hole in the groove is closed. , There is a high-pressure airflow (compressed air) in the axial direction of the launching wheel to transport the mouth stick to the mouth stick receiving station on the cigarette equipment at high speed through a closed pipeline, providing the required mouth stick for the production of cigarette equipment.

A photoelectric signal detection device is installed at the output end of the mouth stick transmitter. When the mouth stick is output by the mouth stick transmitter and passes through the photoelectric signal detection device, there is a certain gap between adjacent mouth sticks, and a pulse will be generated. Signal, the photoelectric sensor on the signal detection device records each pulse signal, and these signals are transmitted to the electric control system, once the blockage occurs (high electric frequency or low electric frequency), the pulse signal will be lost, and the operation control of the mouth stick transmitter The "blockage" alarm signal is displayed immediately on the screen, and this signal detection device also has the counting function of the mouth stick.

The existing nozzle stick transmitter pipeline signal detection device uses a through-beam optical fiber sensor, which often occurs "blocking" failures during use. High requirements, because there is a lot of paper dust on the surface of the nozzle rod, so the paper dust dust is easy to fall off and accumulate in the channel during the launch process of the nozzle rod, which reduces the intensity of the through-beam optical fiber signal, and is often mistaken for "blocking". "failure caused the nozzle rod transmitter to not work normally; in addition, the through-beam optical fiber sensor is installed on both sides of the output channel of the transmitting wheel, which makes the installation and debugging process more complicated and time-consuming, and the process of checking or judging the fault is very difficult. trouble.
