Region and time impurity remove region, the two regions are associated with the band tooth surface for roller of loosening and are connected to for removing impurity
Air vacuum system.
Background technique
With the associated problem of production textile product first is that removal is introduced by processed material the impurity in machine
Or the impurity as caused by processing material.The cleannes of machine and its device are in the processing of fine materials, for example in the life of yarn
It is especially important in production.In order to remove impurity, machine is commonly equipped with vacuum pick-up system or gravity system.Their purpose is first
It is the hard impurity eliminated include in fibrous material, and in the case where free end (open-end) spinning machine, main purpose
It is to prevent the gathered trough of spinning rotor from blocking.
Well-known impurity removal system can remove hard and relatively heavy particle.On the other hand, weight is very low
The very short part of small and thin dust granule or fiber be actually unable in it is enough by suction removal.This is especially suitable for as follows
Those fields for technical reasons, exist close to suction system for going deimpurity vacuum values in those described fields
High negative pressure.
Thus, for example, document DE102008037000A1 passes through the Interior Solutions using thermal pressure steam injection spinning rotary cup
The cleaning determined after interrupting spinning process and after opening spinning unit to the gathered trough of spinning rotor.
According to DE102008026776A1, the device with electrically driven (operated) rotating brush is clamped after opening spinning unit
To the front of the unit, then, the brush cleans gathered trough and aspirates loose impurity.
In the case of US6321521B1, spinning process is also interrupted and the lid of spinning unit is not covered with, in
It is that the oral area of the suction tube of adjacent service robot apparatus is brought to the inside of revolving cup, close to gathered trough.The rotor
By be also service robot apparatus a part friction plate rotation, and accelerate to the impurity that wherein adheres to by from
Mental and physical efforts influence and are then sucked the speed that pipe pumps out.
It is evident that described device is complicated, and importantly, they need to adhere to spinning unit in removal
Interior section particle during interrupt machine manufacturing process.
CZ304228B6 solves the impurity of the amount from the fibrous material removal maximum possible being spun into inter alia
Problem.For this purpose, being moved in the position that sliver (sliver) is fed into roller of loosening (opening roller) with by fiber
To the hole between the position of spinning rotor, existed for impurity removal, which is connected to ambient atmosphere.On the other hand, which uses
In removing impurity, and another aspect from the sliver loosened, by the hole, the required air that spins passes through vacuum system
It is sucked into.Obviously, it aspirates this air and does not hinder the heavier grit of removal, but it is unfavorable for removing thin and light
Particle.
CZ262402B2 discloses a solution, wherein main impurity removal region is directly arranged at region of loosening
In (opening zone), i.e., just beyond the edge for fiber to be fed into the entrance for roller of loosening, i.e., in wherein fiber
Rear end still by sliver feed arrangement by fixture clamping line (nip line) in keep region in.In the embodiment of fig. 2,
Although the edge of sieve from entrance opening is fartherly mobile, it is disposed with suction hole on two sides in region of loosening, institute
It states suction hole to be covered with for the sieve from the direct foreign substances in region of loosening, this some holes is connected to centre gangway by channel.
The shortcomings that embodiment, is the fact that in region of loosening, sliver only starts loosely, and therefore impurity only starts to release
It puts, and then since above-mentioned illy loose sliver, wherein the rear end of fiber is still fed device holding, dust
Fine grained and the very small part of fiber (have low-quality particle) without sufficiently discharging and being then sucked away, this
Mean these particles not with this effect desired such as in modern machines from fiber removal.Further drawback is this paper
Described in passing away simultaneously with the air supply portion of spinning rotor is accomplished, this makes the function for removing small and very small impurity
Effect further deteriorates.
Summary of the invention
The purpose of the present invention is the places for preventing small and light particle from can not easily remove from it at them to occur to block up
Plug and subsequent solid deposit, and propose even to stop being used in the case where production process during the operation of spinning machine
Early stage removes the device of this particle.
The purpose of the present invention passes through the very small part for removing impurity, particularly dust granule and/or fiber
Method realizes that principle is, in main removal region, just behind region of loosening (downstream), from center tube
Vacuum acts against on fiber and impurity, and then in secondary removal region, centrifugal force and the vacuum from center tube are made simultaneously
With on fiber and impurity.This mainly region downstream and is realized by being placed on main region to loosen next to region is loosened,
Its small particles is most readily by vacuum to remove.
Preferably, the size for the impurity for being sucked out is limited by sieve, and particle is sucked by vacuum out by the sieve
Come, single sieve hole, which has, is no more than 1 mm2Area of section.
The purpose of the present invention also by in spinning unit from sliver remove impurity, particularly dust granule and/or
The device of the very small part of fiber realizes that principle is, main removal region is arranged in loosen and region downstream and time go
Except region upstream, thus the width in main removal region corresponds to the working width for roller of loosening, and main removal region and time removal
Region is connected to the vacuum system for pumping out impurity.
