AI Technical Summary

Problems solved by technology

Not only that, once the shredded tobacco is retained, new shredded tobacco will be continuously deposited on it, which will soon cause blockage of the shredded tobacco in the fluidized layer
Such clogging of shredded tobacco will cause the entire cigarette rolling machine to stop.

Embodiment Construction

[0020] figure 1 A part of the shredded tobacco conveying device of an embodiment is schematically shown. The shredded tobacco conveying device has a gravity chute 2 extending in the vertical direction. Needle rolls 4 and cut-in rolls 6 are arranged at the upper end of the gravity chute 2 . The shredded tobacco is dropped from above the pin roll 4 and supplied. When shredded tobacco passes between the needle roller 4 and the cutting roller 6, it is adjusted to fall into the gravity chute 2 in a certain amount.

[0021] The shredded tobacco conveying device has a conveying passage 8 . The transport path 8 extends laterally from the lower end of the gravity chute 2 . A first damper 10 is arranged before the entrance of the conveyance path 8 . The first damper 10 blows jet air laterally below the gravity chute 2 and sends the air into the transport path 8 . The transport path 8 extends in the air blowing direction of the first damper 10 , bends upward along the upper surface...

Abstract

A shredded tobacco conveying device. It has a light sensor (40) that detects tobacco retention in the secondary sorter (20). The optical sensor (40) detects the inside of the secondary sorter (20) in the width direction, and emits and receives detection light at a position below the air lock (18) where stagnation is likely to occur. When the detection light is blocked by the stagnant cut tobacco, the controller (58) detects the stagnation according to the detection signal, and activates the alarm (60). Furthermore, the controller (58) operates the air vibrator (62) to release the stagnation.

Description

technical field [0001] The present invention relates to a shredded tobacco conveying device for conveying shredded tobacco to a cigarette band of a cigarette rolling machine. Background technique [0002] In the process of conveying shredded tobacco to the cigarette belt, this kind of shredded tobacco conveying device blows air into the shredded tobacco to separate the tobacco stems mixed in the raw shredded tobacco and the cut products (butterfly leaves) during shredding, etc. by winnowing. Specifically, the shredded tobacco conveying device generates an air flow towards the cigarette band, and makes all the shredded tobacco fall uniformly into the air flow. Here most of the shredded tobacco forms a fluid bed together with the air flow. On the other hand, the heavier cut tobacco falls through the air stream. At this stage, the heavy cut tobacco (most of which are stems and leaflets) is separated for the first time from the whole cut tobacco. [0003] The heavy shredded t...
