Description

Flat pin knitting machine

Technical field

The present invention relates to a kind of flat pin knitting machine (Flachstrickmaschine), it is used for monitoring from the yarn testing fixture that is arranged at least one needle-bar top of knitting line (Strickfaden) of bobbin (Fadenspule) extraction with a large amount of.

Background technology

In the knitting machine in modern times, such yarn testing fixture is corresponding to be arranged between bobbin and the machining area.It usually has Yarn Brake, tubercle monitor (Knotenwaechter) and yarn break sensor and evens up stretcher (Aufholspanner).For flat pin knitting machine, above needle-bar, be provided with support, be furnished with a large amount of these testing fixtures at Qi Chu, because each thread-carrier of knitting machine must be associated with at least one such testing fixture.

In present machine, all yarn testing fixtures are vertically arranged needle-bar with adjoining.Yet, being supplied to the knitting machine of thread-carrier for twisting thread from the top, this layout causes some difficulties.Near the yarn testing fixture, yarn is not enough scattered doughtily, so that the yarn that intersects can be in contact with one another and therefore keep strand together.Therefore in many knitting machines, be furnished with other conducting mechanism in the end, its fan-shaped of being responsible for necessity of yarn is scattered and is responsible for being supplied to uninterruptedly thread-carrier.Yet this wiring system causes the other load that turns to and therefore cause knitting line.

From above supply with the situation of yarn, used the yarn testing fixture of adjustable in length, with the contact of the yarn avoiding intersecting.When whole yarn testing fixtures mobile, the mobile route on the thread-carrier track is relatively far away, and this makes the structure of such yarn testing fixture very complicated.If thread-carrier at the volley in addition, then also utilize the mutual yarn contact of yarn testing fixture eliminating of such adjustable in length to generally acknowledge it is difficult.When wanting weave pattern (for it, a plurality of thread-carriers must drive with opposite direction), be so more.The device for the machine that weaves mentioned decorative pattern like this designs equally very complicatedly and needs assembler's more experience.

Summary of the invention

Therefore, the object of the present invention is to provide a kind of flat pin knitting machine, the yarn testing fixture also can be realized for unskilled user simply with respect to the association of thread-carrier therein.

This purpose realizes by a kind of flat pin knitting machine, it is with the yarn testing fixture that is arranged in a large number at least one needle-bar top (its corresponding have at least one tubercle monitor, Yarn Brake, yarn break sensor and even up stretcher), it is characterized in that the yarn testing fixture vertically adjoins ground and vertically is arranged offset from each other at least in part transverse to needle-bar at needle-bar.

The layout that is offset longitudinally transverse to needle-bar by the yarn testing fixture can be got rid of the contact between the yarn of intersection simply, because each yarn can be directed in other plane.When thread-carrier (yarn is supplied to it) is mobile, so do not produce the yarn contact yet.

When the yarn testing fixture is bearing in one or more common support place, for whole machine to be configured in this be favourable, (a plurality of) support a plurality of parallel thread-carrier tracks (being furnished with at least two thread-carriers in that its place is vertically corresponding movably) top needle-bar vertically on and transverse to this extension.In order to ensure the yarn testing fixture transverse to needle-bar vertically and therefore also have the layout of thread-carrier track vertical misalignment, can have such trend in the plane of support level above the thread-carrier track in of the present invention one preferred design, namely each thread-carrier of needle tray (Spur) is associated with at least one yarn testing fixture.To this, (a plurality of) support for example can have the trend of V-arrangement or W shape in the plane of this level.Therefore, the yarn testing fixture can be as being arranged in the support in the known machine with being adjoined, however because at least in part mutually skew of its shape.But at least one yarn testing fixture can certainly be realized in the mode that is different from by support common, that correspondingly form by the association that mutually is offset longitudinally transverse to needle-bar with respect to each thread-carrier.Therefore, the yarn testing fixture for example also can be movably disposed within the machine place in the horizontal.

When support when the whole length of flat pin knitting machine is extended, draw additional advantage.Also can easily make the decorative pattern that needs the different in a large number complexity of knitting line in this mode.Because each thread-carrier track usually is equipped with at least two thread-carriers and usually weaves in the zone line of machine, so if the support mid-plane that is symmetrical in flat pin knitting machine is constructed in addition, then be favourable.

Each is knitted line and certainly also can be in the arrangement according to the invention scheme of yarn testing fixture further be supplied to each thread-carrier via the conducting mechanism in the end of flat pin knitting machine, yet the layout of the skew by the yarn testing fixture may be cancelled the conducting mechanism of such side direction and directly from the top yarn is supplied to thread-carrier.When the yarn testing fixture that is associated with thread-carrier is arranged in the track top of this thread-carrier, be particularly advantageous at this.Being in contact with one another when thread-carrier moves of yarn of intersecting be supplied to the yarn of each thread-carrier to be retained in so by in the defined vertical plane of thread-carrier track, so that also can be excluded.

Description of drawings

The below describes the preferred embodiment according to flat pin knitting machine of the present invention with reference to the accompanying drawings in detail.

Wherein:

Fig. 1 has shown the schematic front view of flat pin knitting machine;

Fig. 2 has shown the top view to the yarn testing fixture support of the flat pin knitting machine among Fig. 1.

The specific embodiment

Has the support 12 that is arranged in frame 11 tops for a large amount of yarn testing fixtures 13 according to the flat pin knitting machine 10 of Fig. 1.These yarn testing fixtures are knitted ray examination tubercle or broken yarn and are typically provided with in addition Yarn Brake for generation of desired yarn tension what extract out from bobbin 14.Yarn directly is supplied to the thread-carrier 15 one from the top or via the

conducting mechanism

16,17 of the end that is arranged in flat pin knitting machine 10 by yarn testing fixture 13.Thread-carrier 15 is arranged in the rail system 18 with a plurality of parallel tracks with longitudinal movement at this, and wherein, guiding has at least two thread-carriers 15 in each track.Thread-carrier is moved along the track of system 18 during the braiding process.Therefore, the yarn of supplying with of two thread-carriers can intersect.As long as yarn does not contact at this, this is not problem.Yarn scatters longitudinally transverse to machine and is usually undertaken by the

conducting mechanism

16,17 of side direction for known knitting machine.Yet one-tenth arranged according to the present invention is knitted line and also can directly (be that is to say from the top) by yarn testing fixture 13 and be supplied to thread-carrier 15, and such contact of the yarn that intersects can not occur.To this (as shown in Figure 2), yarn testing fixture 13 is arranged in support 12 places of V-arrangement ground bending in shown example.It (that is to say transverse to machine) to have mutual skew thus vertical on the direction of double-head arrow 19.Support 12 should form like this at this, so that a top in the track of the corresponding rail system 18 that is arranged in thread-carrier 15 of the outlet eyelet of yarn testing fixture 13.In this mode, be supplied to the yarn of thread-carrier 15 being extended in the defined vertical plane by this track by corresponding yarn testing fixture 13.The V-arrangement of support 12 causes, and in the yarn testing fixture 13 two are corresponding to be arranged in the identical position in the direction of arrow 19, that is to say to be associated with identical thread-carrier track.When having two thread-carriers in each thread-carrier track, this generally acknowledges is favourable.For the machine of each track with four thread-carriers, support 12 also can be configured to for example W shape, so that four corresponding can being associated with a thread-carrier track of yarn testing fixture.By this design of support 12, for the unskilled assembler of machine 10, it also is simple that yarn testing fixture 13 is associated with thread-carrier 15.It needn't be concerned about the motion of each thread-carrier 15, in order to can get rid of the contact of knitting line.

But support 12 is also constructed on multi-piece type ground.Alternatively, a plurality of supports also can be arranged with adjoining.
