Abstract

The invention relates to a method and device for producing fabric and cylinder socks with single fabric cylinder knitting machine. The cylinder knitting machine uses new sheets instead of usual knitting settling sheet to keep down upon the motion of fabric sheet among the knitting needles. The knitting needles only work with the syringe and the needle groove to pick-up and string the yarns to form coils. Then when the knitting needles go up, they attempt to lift the fresh coil together. The problem can be resolved with the help of the sheet provided with at least one end part. The sheet gradually enters among the knitting needles as a moving coil comb to prevent the fabric going up or push the fabric ahead.

Description

On single jersey circle latitude machine, generate the method and apparatus of knitted fabric and tubular socks product

At present, the method that forms coil on the single jersey circle latitude machine is followed general rule, that is, knitting needle hooks up yarn and weaves under the help of common lopping sinker then and finish knitting cycle.In general, good up to present this method product quality when plane No. is produced lightweight fabric on up to the knitting machine of 36gg (knitting needle per inch).And making the knitting machine producer have to continue the described knitting machine plane No. of raising to the ultralight knitted fabric and the endless market demand of tubular article, this is a quite target of difficulty.On technology and since near general knit fabrics resemble the limit of knitting needle and lopping sinker, other problem has appearred in (from per inch 40 to surpassing 50 knitting needles) single jersey circle latitude machine that plane No. is very high.

In fact, it is very thin that described parts become inevitably, almost arrived inharmonic degree, and the thickness of single piece of knitting needle is reduced to only 0.26 millimeter sometimes.

This has greatly reduced operates knitting space, produced on the series of process and knit product on problem, wherein be stressed that reduced operating rate, the knitted fabric product quality descends and because described parts: the increase of the cost that brings is changed in the acceleration of knitting needle and lopping sinker.Mainly be, in the online circle formation process existence of common lopping sinker no longer useful because described sinker is too thin, be difficult to bear pressure, vibration and swing, to influence the quality of single coil or ring inevitably.So, the demand that conventional method in the modern knitting process and mode can not satisfy contemporary knitwear and hosiery industry complexity under special circumstances in correct mode, as if the present age, knitwear and hosiery industry were more prone to produce fabric in light weight and resilient, even use more yarn and elastomeric yarn to feed the such fabric of production in the same piece of knitting needle simultaneously sometimes.

Main scope of the present invention is elimination or greatly reduces the technology of described method and mode and the restriction on the function.

The other scope of the present invention provides a kind of method and relevant device, be used on single needle bed hosiery machine and knitting machine, producing knitted fabric and tubular woven fabric, described hosiery machine and knitting machine plane No. are very high or fineness is very high, and plane No. is up to 50 even higher, and the mode of production is more economical, safety and more effective.

Further scope provides a kind of method and relevant device, and at first they directly feed yarn and form coil in the knitting needle, need not the help of traditional lopping sinker, but in particular cases uses the needle tray (trick) of syringe to replace the lopping sinker at this; Then, pass the coil of new formation for knitting needle is risen, many thin plates that radially alternately flow are drive on boldly forward to push down or fabric is promoted forward between described knitting needle.The other scope of the present invention is the motion by the described thin plate of relevant control heel control, and these control heels are according to being equipped with the sheet metal cover of suitable triangle to be directed to, with to be used for controlling those of described lopping sinker at present similar.

Except last claims, from specification, embodiment and accompanying drawing, obtain further target and scope.Feature of the present invention and various beneficial effect will become clear from the description subsequently that circle of reference latitude machine carries out, this circle latitude machine is equipped with the rotation syringe, latch needles is arranged in the syringe but do not have common lopping sinker.Consider syringe diameter, plane No., yarn feeding number of times, knitting needle type other technology and textiles parameter and model, the present invention relates to the general single jersey knitting machine that is equipped with the single needle bed together with each knitting machine producer.

Some embodiment of prior art describe in Fig. 1-3.

Fig. 1 schematically illustrates the side view of rotation syringe CIL, and this syringe generally has outside sinker annulus APE and inner sinker annulus API.

Holding knitting needle AC among the syringe CIL, knitting needle and lopping sinker PM Collaboration, lopping sinker PM radially flows between contiguous needles and passes through control heel TC controlled motion, and the control heel is controlled by many triangles, and these triangles are installed on common the sinker cover or sinker cover CP.

By a kind of like this mode, generate particularly jersey MR or more generally generate various types of single jersey MJ.

Fig. 2 is the zoomed-in view that carries out the coil MR-MJ of technology Collaboration generation between the working face PAP of yarn, knitting needle AC and lopping sinker PM.

Fig. 3 has shown in detail from the front by knitting needle AC and lopping sinker PM and has alternately arranged the common combining form that forms.

The present invention relates to be used to produce the little bobbin radius single side knitted fabric circle latitude machine of socks product, and the single jersey knitting machine of big barrel dliameter, two types machine all is equipped with knitting needle still not have common lopping sinker but replaces with the syringe needle tray, and the roof of described syringe needle tray is parallel fully or preferred level and smooth as the SS among Fig. 4.According to the present invention, online circle forms the phase I of process, and yarn is (DA of Fig. 9) feeding knitting needle AC in knitting needle decline process; Described knitting needle hooks up at least one one thread from common thread-carrier and forms coil, need not the Collaboration with traditional lopping sinker PM of syringe needle tray SC replacement.

In second stage, when knitting needle AC rises (SA among Fig. 9), they attempt to promote the coil of new formation, the situation of having avoided this danger owing to existence and the effect of many thin plate LPM (Fig. 7), thin plate LPM front is equipped with at least one attachment part EA, and is promoted gradually to prevent the lifting of fabric as the coil comb that moves between described knitting needle.What deserves to be mentioned is and traditional lopping sinker PM move and pliable and tough opposite, syringe needle tray SC is quite hard, so they can further reduce dimensionally and can become level and smooth on the top; But the most important thing is that they can not be subjected to the influence of projection, depression (SOLICITATIONS) and the vibration of any kind.In this embodiment, cyclinder needle preferably only has outside or outside annulus, and this is similar with the annulus that is used for lopping sinker PM now (APE of Fig. 1).

Described annulus APE has the radial slot or the groove of top level, and they can hold thin plate LPM (Fig. 6-8) many and that knitting needle is alternately arranged, and predetermined machinery and the braiding planning work of thin plate basis between knitting needle.General ascent stage SA in Fig. 9, knitting needle AC applies disadvantageous pressure towards newly-generated coil, and the preceding terminal EA by making thin plate LPM between knitting needle has been avoided the generation of great danger by forward or side drive in the syringe by the specific function of coil comb that moves and/or fabric depression bar.Significantly, described thin plate LPM can change or revise their shape and operating position, if particularly fabric traction equipment comprises the passage (R in Fig. 7 and 11) of fabric MR-MJ above inner syringe annulus, thin plate can be placed on common coil formation and highly compare higher position.

PM is similar with the coil sinker, and the radial motion of described thin plate LPM and angular movement be by triangle track control, and the triangle track is connected to very similar cover or the lid of sinker cover CP that shows among they and Fig. 1 and descends (not shown), and can carry out different adjustings.

Such triangle is used for driving the control heel TC of thin plate LPM, and the control heel is arranged among the outer toroid APE of cylinder knitting needle, and the outer toroid of holding lopping sinker PM among this outer toroid and Fig. 1 usually is similar; Arrive this,, needn't do further explanation again because prior art has had the introduction of this respect.Described thin plate LPM, in fact in horizontal level work, preferably but must be along the P-LPM path among Fig. 9, the vertical motion of the cylinder knitting needle AC in this path and each single yarn feeding work be relevant.

Generally, Fig. 9 has schematically shown the plan view of syringe CIL with relevant knitting needle AC.P-A shows knitting needle at their rising and the waveform trace in the descending motion process, and P-LPM shows the thin plate alternate path (enter-come out) relevant with knitting needle AC.In the time of on being in the horizontal line that WT shows, thin plate LPM arrives the advance maximum point of (or towards syringe CIL inboard) towards syringe CIL, preferably on knitting needle, obviously be positioned at top or (pressure) fabric MR-MJ of fabric MR-MJ, as the position of signal demonstration among Fig. 7.

In the embodiment that the present invention simplifies, cylinder knitting needle does not dispose the triangle of outer circle ring APE, thin plate LPM, their cover CP and control heel TC again.In this specific embodiments, the function of this described thin plate LPM is in fact finished by the equipment that the little horizon bar that tightly is placed on the knitting needle inside circumference forms, consistent with yarn feeding each time, in Figure 10-12, be denoted as APM, be easy to the tractive fabric, Figure 11 also shows knitted fabric MR-MJ through annulus R, is placed on syringe CIL inboard and compares higher corresponding to the coil formation position on syringe top.In this manner, bar APM is easier to increase the pressure that is pressed on the knitted fabric MR-MJ.Can in very large range carry out the described fabric depression bar APM of position adjustments, be fixed to (not shown) on adjacent thread-carrier or the common bigger and firm yarn carrier ring that suspends by forearm or connecting rod.

The main purpose of this fabric depression bar APM is to finish the rising of knitting needle when yarn feeding each time, prevents that simultaneously them from promoting fabric.In different embodiment, replace aforesaid fabric depression bar APM also can reach same result with the disk DPM among Figure 14, this disk is to make with different material (metal, plastics etc.), pass preferably that forearm or connecting rod are fixed to usually firmer adjacent thread-carrier again or the yarn carrier ring (not shown) that suspends on.

Can in very large range carry out the fabric depression bar of position adjustments or the very approaching fabric that is weaving at present in bottom of disk DPM, so that in the knitting needle uphill process, maintain or make fabric to remain on very low position in this fabric.

Disk DPM, if be reduced to gently the contact and the direct position of the fabric that generating of contact, the cyclinder needle of meeting and rotation be consistent continuous service.Consider from technological angle, also may use the outward flange or the circumference of the last dials of using on the common double jersey circular knitting machine, can suitably revise if desired, they also have the additional function of the fabric depression bar that rotates together with following cyclinder needle.

Last embodiment of the present invention is illustrated schematically among Figure 13.Thin plate LPM is placed among the cyclinder needle CIL, by the combined radial swing of annular triangle K and preceding attachment part Y.Described thin plate LPM is moving radially between two adjacent knitting needles and as the lopping comb that moves, and also is raised when knitting needle rises so that prevent the new coil that forms.The present invention includes the other embodiment that those skilled in the art expect, so the just necessary signal of present description result is described.The details of implementing can be different on form, material, size and position; 11 aspects that comprise in the above description or that show in the accompanying drawings only are exemplary, are not a kind of restriction.
