Problems solved by technology

The conveying air is used to compress the fiber batts accumulated in the flocculation tunnel. The disadvantage is that in practice the conveying air conveying the fiber flocs into the upper storage box fluctuates, so that the separated conveying air is also largely useless. regular

Embodiment Construction

[0011] According to Fig. 1 - opener 1, such as TXL4 Trützschler opener, a fibrous material separator (Fasermaterialabschneider) 2, such as MAS Trützschler material separator, a fibrous material with opening device 4, such as dosing opening roller A store 3 , for example a MSC Trützschler material store, and a fiber batt feeder 5 , for example a Trützschler SCANFEED, are connected sequentially to one another. Instead of the opening roller, it is also possible to use a yarn clearer, for example a Trützschler CVT4 yarn clearer. Use A to indicate the working direction.

[0012] Between the opening roller 1 and the material separator 2 there is a duct 6 for the pneumatic feeding of the fiber batts, and between the dosing opening roller 4 and the fiber batt feeder 5 there is a duct 7 . The fibrous material is removed from the last roll 1 a of the four-roll opening machine 1 by means of an air flow B which is sucked in by a fibrous material conveying fan 8 arranged in the duct 6 . ...

Abstract

An arrangement used for filtering out conveying air when supplying fiber material, e.g. cotton and the like to a processing machine is provided. The arrangement has an essentially vertical filling chute for the fiber material, the chute having a device with pneumatic fiber feed at the upper intake opening, and a floccule-forming device at the lower exit opening including a system of draw-in rolls and a fast-rotating opening roll. The chute includes at least one air-permeable surface for separating the fiber material from the conveying air. An evacuating device evacuates the filtered out conveying air. An exhaust air device is coupled to the evacuating device and has an air stream regulator which is connected to a control and regulating device. The conveying air stream is guided along the opening roll, and a partial air stream of the filtered out conveying air is guided into the exhaust air device.

Description

technical field [0001] The present invention relates to a device in a spinning preparation plant for separating and conveying air when fibrous material, such as cotton, etc. Equipped with a device with pneumatic fiber input, the outlet below which is equipped with a flocculation device with a feeding device and a high-speed operating opening roller, in which there is at least one for separating the fiber material from the conveying air flow (separated) air-permeable surfaces and a device for discharging the conveying air which is introduced along the opening rollers. Background technique [0002] In a known device (DE-OS 3217668), the entire delivery air flows along the opening rollers and into a downstream flocculation tunnel with air-permeable walls. The conveying air is separated from the fiber batt and then discharged, while the fiber batt is conveyed further by the conveying rollers. The conveying air is used to compress the fiber batts accumulated in the flocculation...
