Background technology
It is well known that the aspirator of spinning machine is used for vacuum fibers structure, especially after broken yarn.In majority of case
Under, aspirator is also sucked into the loose fiber and dirt of some residual.The especially glued portion of dirt, such as honeydew, lubricant,
Oil and water, As time goes on deposit in aspirator inwall, hereafter arduously must remove it, generally clear using machinery
Clean method.For the suction channel that certain bends, as described in patent document DE19733614A1, also occur and ask
Topic.The bending of suction channel even increased the cleaning difficulty in dirt area.
Patent document DE2643902A1 describes another kind of cleaning side for being applied to open-end-spinning (open-end spinning) machine
Method.The method is cleaned simultaneously to pipeline to a certain predetermined of a relatively high flow velocity by regularly increasing instantaneous suction airstream
Make which unimpeded.However, this cleaning mode is only applicable to remove the dirt in the aspirator for vacuum fibers structure.Because
The of a relatively high suction airstream of one side flow velocity can have a negative impact to intact fibre structure, on the other hand still cannot be clear
Except obstinate sticky foulant.
Additionally, patent document CH496824 discloses a kind of very expensive aspirator.In the suction channel of the device
There is a filter screen, especially fiber and fracture rove can accumulate in this.Similarly, the filter screen is kept off by a certain cleaning is aperiodically passed through
Plate flows into the air-flow of suction channel and is cleaned.
The content of the invention
Present invention aim at providing a kind of method and a kind of aspirator, it is easy to preferably process dirt.
The object of the invention can carry aspirator by an aspirator, a spinning machine with aspirator and one kind
Suction method be achieved, which has the feature of independent claims.
The aspirator suggestion of spinning machine is with least one suction opening, a connection opening and a segment pipe section.
The suction opening for being arranged in aspirator one end is used for vacuum fibers structure, especially aspirates the fiber knot after broken yarn
Structure.Additionally, also suction is located at the loose fiber and dirt of yarn Operational Zone.
The connection for being arranged in the aspirator other end is open for connecting a certain negative pressure device, and the negative pressure device can be produced and be taken out
Negative pressure needed for inhaling, is generally used for several aspirators.
The duct section being open for a connection suction opening and connection of aspirator go-and-retum is arranged in, the duct section also has
A connection opening and several suction openings may be connected, in this case, the duct section has corresponding branch.
Duct section is also disposed with the dirt collecting chamber for collecting dirt deposition.The setting of dirt collecting chamber expands pipeline
The cross section of section, the cross section of the expansion cause duct section to reduce in the suction airstream that dirt collects chamber region, heavier dirt
Constantly gather in the region, lighter fiber part then continues to follow higher suction airstream.Thus the region of accumulating foulants obtains
Separated with the region with most of fiber movements, so as to the dirt of accumulation is without compromising on fiber.Gather in dirt collecting chamber
Dirt does not interfere with suction airstream yet.Before needing to carry out scale removal to aspirator, difference of the dirt collecting chamber according to size,
A considerable amount of dirts can be collected.
Additionally, arranging moving element in the region of duct section and/or dirt collecting chamber.The moving element is at least one work
Make movable between position and at least one cleaning position.
According to the present invention, an opening is discharged in the dirt collecting chamber positioned at cleaning position, can be to dirt by the opening
Collecting chamber is cleaned.Which greatly simplifies the cleaning of dirt collecting chamber.Negative pressure, compressed air or machinery side can be passed through simultaneously
Method (such as using brush) is cleaned.The cleaning process can pass through robot (i.e. tube wall cleaning device) or operator come real
It is existing.
If some region of axis direction of duct section changes, hereinafter referred to as crooked pipeline, then dirt collecting chamber is located at
The region or to be close to the region be favourable.Dirt in crooked pipeline region is particularly acute：Suction airstream is usually not
It is strong to being enough to make heavier dirt particles move along crooked pipeline, dirt particles due to self inertia fly to crooked pipeline outward
Side.The dirt of especially severe can be then produced in this position.If dirt collecting chamber is arranged in this region now, especially exist
The outside of crooked pipeline, then can collect dirt, and suction airstream and longer fiber can be passed through unaffected herein.

Locking at one and multiple operating positions is even more important, it is ensured that aspirator uninterruptedly runs, makes movable unit
Part will not leave desired location automatically.Locking device also has practicality in cleaning position, and it locks moving element, makes to clean
Journey is not obstructed.
It is favourable with multiple operating positions.The side of moving element forms a part for extraction opening, according to movable
Operating position residing for element is different, suction opening it is of different sizes.Different size of suction opening is applied to different thicknesses
Yarn：Little suction opening correspondence fine yarn, big suction opening correspondence textured yarn.
An advantageous improvement of the invention is the design of clean bits, and in clean bits, which is located at spinning machine to moving element
Yarn Operational Zone.This can be avoided moving element from being spinned still in (spinning machine) during clean bits again.
In order that moving element and the duct section adjacent with moving element and/or dirt collect chamber region fully seal, should
Make its accurate closing.Additive method is may also be employed, such as：By sealant, especially foam rubber, at least one surface is attached to
On, or engaged using labyrinth teeth between surface, to strengthen its air-tightness.
Another favourable improvement of the invention is that moving element is a flap.The side of flap is at least one operating position
Form the side of suction opening.Additionally, flap also constitutes one section of wall section of dirt collecting chamber and duct section, duct section essence
On be straight, only expanded in flap region.If flap is moved in cleaning position, which can discharge one for dirt collecting chamber
Big opening.When flap is located at cleaning position, duct section does not substantially bend, and thus can easily clean dirt collecting chamber and pipe
Road section, such as using the burnisher of straight trip.Additionally, flap stretches into yarn Operational Zone when being located at cleaning position, folding thus can be avoided
Plate spinning machine spinning at the position.
Finally, duct section and/or connection opening with closing means and one be located at moving element and the closing means it
Between machinery and/or mechatronics be favourable.The connection design is as follows：When moving element is located at cleaning position, it will envelope
Close the position that mechanism shifts to closing aspirator.So can be when dirt collecting chamber be cleaned, it is to avoid unnecessarily aspirate a large amount of
Air.Meanwhile, the spinning in other spinning areas being connected with same negative pressure device can proceed with.
Additionally, it is proposed that, a spinning machine carries multiple spinning areas and a pumping equipment.Each spinning zone has
One drafting system and a vortex generator.The pumping equipment carries above-mentioned at least one aspirator.These spinning areas and suction
Device is arranged to each spinning area and is furnished with the form of a suction opening, so can after broken yarn vacuum fibers structure and
Loose fiber and dirt are aspirated in spinning operation.Due to the unique design of pumping equipment, the process of collect dirt is simplified.
