Device for detecting number of cigarettes in cigarette packet

Abstract

The invention provides a device for detecting the number of cigarettes in a cigarette packet. The device comprises a support seat and at least one set of infrared detection component, wherein a groove is formed in the lower end surface of the support seat; the infrared detection component is arranged in the support seat and comprises an infrared ray emitting tube and an infrared ray receiving tube; the emitting terminal of the infrared ray emitting tube and the receiving terminal of the infrared ray receiving tube are stuck into the groove; the light emitting optical axis of the infrared ray emitting tube and the light receiving optical axis of the infrared ray receiving tube are located in the same plane; the included angle between the light emitting optical axis and the lower end surface of the support seat is equal to that between the light receiving optical axis and the lower end surface of the support seat. The emitting terminal of the infrared ray emitting tube is used for emitting light to irradiate the cigarettes, the light is reflected by the surfaces of the cigarette to irradiate the receiving terminal, and a processing circuit can judge whether the cigarette packet is short of cigarettes according to the intensity of received light. The device is simple in structure and convenient to use, and is not in direct contact with the cigarettes so as not to damage and contaminate the cigarettes.

Description

technical field [0001] The invention relates to a detection device for lack of cigarette packs. Background technique [0002] In the automatic production process of cigarettes, it is necessary to detect the number of cigarettes in the cigarette box before packaging the cigarettes, so as to prevent the shortage of cigarettes in the packaged cigarette package. [0003] At present, mechanical contact detection is used to detect the lack of cigarette packs, but because its installation location is close to the cigarettes, and because the cigarettes vibrate in the mold box when the machine is running, it is inevitable that there will be some damage during production. Cigarettes cause damage and pollution. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a detection device for missing cigarette packs, which does not directly contact with the cigarettes to be detected. [0005] In order to solve the above-mentioned tec...
