Description
The present invention relates to a kind of Yarn-recovering device for Weaving device.
Yarn-recovering device is known, and it is suitable for the upstream for being positioned at common textile machine, is previously divided to reclaim
A part for the yarn of dispensing machine, and then returned it in later time.
A kind of retracting device is disclosed with the nominal EP1741817B1 of same applicant, it is provided with can be thereon
The Mobile rotating spool of winding yarn to be recycled.In the above documents, spool has continuous cylindrical outer surface.Yarn is passed through
Cross the passage on the preceding surface that spool is obliquely run out to from the outer surface of spool.
As known to those skilled in the art, in order to optimize the precision of braiding (weaving) process, especially with regard to entering
The mechanical tension of yarn is controlled to period, it is important that, the various devices being related to during being somebody's turn to do have high reaction speed, and
And therefore, moving component provides low inertia.
It is an object of the invention to provide a kind of Yarn-recovering device, although it is based on mechanically filling with above-mentioned spinning reel
The similar operating principle of the operating principle put, but it has can improve its structure for operating reaction speed.
The purpose and other purposes are will become more apparent according to following description to pass through with institute in appended claims 1
The Yarn-recovering device for stating feature is realized, and accompanying independent claim defines the further feature of the present invention, these other spies
It is favourable to levy, despite secondary.
The present invention is more fully described referring now to the preferred but non-exclusive embodiment of the present invention, the embodiment
Shown in the accompanying drawings for the purpose of non-limiting example, in the accompanying drawings：
Fig. 1 is the perspective view of the Yarn-recovering device according to the present invention；
Fig. 2 is the side view of Fig. 1 Yarn-recovering device；
Fig. 3 is the view similar with Fig. 2, and it illustrates the Yarn-recovering device in different active positions.
Refer to the attached drawing, Yarn-recovering device 10 is suitable for being previously allocated to down for reclaiming along yarn feeding line arrangement
A part for the common textile machine (such as be knitted (knitting) machine) of trip or the yarn of framework, and then later when
Between return it to.Just to the purpose of example, Yarn-recovering device 10 can be arranged in yarn feeder (for example, storage yarn
Line feeder or spinning reel yarn feeder) between textile machinery, or the upstream of yarn feeder can also be arranged in.
Yarn-recovering device 10 includes the motor 12 being contained in support member 14, and is provided with drive shaft 16 (Fig. 2).Line
The key of axle 18 is connected in drive shaft 16, and can be activated, and is reclaimed being partially wrapped on bobbin 18 for yarn with will pass through
It is previously allocated to the part of the yarn of the machine in downstream.
Bobbin 18 is axially defined front end face 18a and towards between the rear end face 18b of motor 12.
According to the present invention, support member 14 integrally carries the first guide bushing 20 and the second guide bushing 22, the first guide
The guide bushing 22 of bushing 20 and second defines the axis A relative to bobbin 18 obliquely through the straight path of bobbin 18, and
Bobbin 18 is provided with multiple radial recess 24, the plurality of radial recess 24 front end face 18a upper sheds and be suitable for by through
First guide bushing 20 and the yarn of the second guide bushing 22 insertion pass through.
Preferably, the first guide bushing 20 and the second guide bushing 22 are arranged so that the path defined by them is located at bag
In the plane of axis A containing bobbin 18.
First guide bushing 20 and the second guide bushing 22 are connected with each other by bridger 25.
In embodiments described here, using bobbin 18 known per se, because it is used in positive yarn feeder,
Positive yarn feeder for example disclosed in the nominal EP 2218670 of the same applicant.
Bobbin 18 includes the framework moulded by synthetic material, and the synthetic material is preferably the thermoplasticity added with carbon fiber
Material, such as nylon.Framework has hub (hub) 28 and a multiple spokes 30, the plurality of spoke 30 be angularly equally spaced and from
Hub 28 extends radially outwardly.Preferably, spoke 30 has air mechanics contour in a rotational direction.Corresponding arm 32 is from spoke
30 outer end protrudes and is substantially parallel to the axis of hub 28.Arm 32 additionally advantageously has air force in a rotational direction
Learn profile.
Preferably, spoke 30 has a cross-sectional profiles of biconvex, and arm 32 have it is raised on the outer surface of arm and
The cross-sectional profiles being slightly concaved on inner surface.
Each that therefore, it can in the radial recess 24 that is passed through by yarn is defined in two adjacent spoke-arms to it
Between.
Protuberance 34 is defined in the join domain between spoke 30 and corresponding arm 32.Protuberance 34 is opposite with arm 32
Direction on obliquely extend laterally relative to the axis of bobbin 18.
The free end of arm 32 is connected to reinforcing ring 36, and reinforcing ring 36 defines framework 26 on rear end face 18b side.
Preferably, reinforcing ring 36 is also made up of the thermoplastic of the similar nylon of addition carbon fiber.
The intervention lower key of co-molded liner insert 44 of the bobbin 18 in hub 28 is inserted in is connected to drive shaft 16.
Liner insert 44 is preferably made of aluminum, and makes it possible to firmly clamp bobbin 18 in the case where no bobbin is deformed
On axle 16.
When not in use, retracting device 10 is in the active configuration shown in Fig. 1 and Fig. 2, and wherein yarn F can be noiseless
Ground by by one in the first guide bushing 20, the radial recess 24 that is defined between two adjacent spoke-arms pair with
And second guide bushing 22 straight path.
For collect yarn, bobbin 18 is set to rotate in one direction, as shown in Figure 3.
In order that yarn is returned, bobbin 18 is set to rotate in the opposite direction, until it is returned to shown in Fig. 1 and Fig. 2
Non-working position.
Control the system that bobbin rotates not within the scope of the invention, therefore be not discussed in detail here.Under any circumstance,
For illustrative purposes, the identical disclosed in the EP1741817B1 referred in the introduction of this specification can be used to control
System.
Due to spoke 30 and the air mechanics contour of arm 32, according to the bobbin 18 of the present invention have the high rigidity of structure,
Low inertia and low aerodynamic resistance.As technical staff will readily appreciate that, this fact is conducive to Yarn-recovering device
To the reaction speed of operational order.
The purpose of protuberance 34 is to prevent the yarn ring being wrapped on bobbin 18 from falling during yarn recovery or return to step
Fall.
The preferred embodiments of the invention have been described, but it is clear that those skilled in the art can want in appended right
Various modifications and variations are carried out in the protection domain asked.
Especially, described bobbin is particularly advantageous above known per se according to yarn feeding.However,
Specially designed bobbin can also be provided, if its have front end face upper shed, in the above described manner with two stationary bushings
Coordinate to allow at least one radial recess of yarn winding.
