Cigarette packet conveying buffer device and method and cigarette making machine

Abstract

The invention discloses a cigarette packet conveying buffer device and a cigarette packet conveying buffer method and a cigarette making machine. The cigarette packet conveying buffer device comprises two conveying belts (5 and 5') which are arranged oppositely in parallel, wherein the distance between the two conveying belts is smaller than the width of a cigarette packet; a cigarette packet running detector (7) is arranged on the downstream of cigarette packet conveying; the linear speed of the running of the conveying belts (5 and 5') is equal to that of a cigarette packet conveying channel (2) in the running state of the cigarette packet conveying channel (2); the cigarette packet is conveyed between the two conveying belts (5 and 5'); a control device controls driving motors (6 and 6') to stop running in the state of receiving a conveying abnormal signal sent by the cigarette packet running detector (7); and the conveying of the cigarette packet and the subsequent cigarette packets is blocked by frictional force between the cigarette packet and the two conveying belts (5 and 5'). According to the cigarette packet conveying buffer device and the cigarette packet conveying buffer method and the cigarette making machine, the extrusion force of the cigarette packets on the cigarette packet conveying channel is reduced, the quality defects of extrusion deformation of the cigarette packets and head retraction of cigarettes are prevented, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the field of automation control in the tobacco industry, in particular to a cigarette pack conveying buffer device, method and cigarette making machine. Background technique [0002] The cigarette packs formed after the cigarettes are packaged in small boxes of trademark paper on the main machine of the packaging machine are transported to the auxiliary machine of the packaging machine through the conveyor belt on the cigarette pack conveying channel for wrapping with cellophane. figure 1 It is a schematic diagram of the cigarette pack conveying channel, figure 2 It is a schematic diagram of the normal operation of cigarette bale conveying on the cigarette bale conveying channel, image 3 It is a schematic diagram of the auxiliary machine shutting down and running when the cigarette pack is conveyed on the cigarette pack conveying channel. like figure 1 As shown, the channel motor 1 drives the conveying belt 2, and the ciga...
