Description
Technical field
The present invention relates to a kind of have be used for the circular knitting machine that wide cut is pulled out the equipment of knitwear (knitwork), this equipment comprises at least two driven work beams, between these two driven work beams, tubular knitted article is squeezed and pulls out from the knitting device of knitting machine by expander, has the equipment that is used for vertically cutting tubular knitted article and above work beam, be positioned at end regions of expander, and have the deployment rod of being arranged to " V " type location below the work beam so that on whole width, launch the vertically knitwear of cutting, and be provided with expanding unit and/or pulling off device and/or the guider and/or the coiler device of the knitwear on whole width at the rear of deployment rod along the knitwear moving direction.
Background technology
As everyone knows, circular knitting machine is made tubular knitted article with known manner on needle-bar.These knitwear are straight close-shaped by means of the expander flare up subsequently, and be squeezed with the form of straight pipe parallel work beam by coiling system, pull out from the knitting system of knitting machine by these rollers then, and be wound on the coiling rod by means of pressure and/or work beam.After finishing coiling and making the tubular knitted article of sufficient length, remove the coiling rod that is enclosed with tubular knitted article from knitting machine, during revising or after the modification that is in the knitting machine outside, knitwear are vertically cut and are expanded on whole width, in knitwear, because fixing on whole width, knitwear are wound into the description of parcels of the knitwear of finishing so that further handle on whole length.
Conventional process for example has substantial shortcoming in the manufacturing of the knitwear of spandex fibre (elastan fibre) comprising elasticity.During pulling out and being wound into tubular form,, generated and failed to remove thereby partly damage the folding thing (folding) of knitwear subsequently by any way from knitwear in the tubular knitted article folded position.
This shortcoming is for example remedied by the method described in the EP0456576B1 that announces and according to the machining of this method.According to this method, tubular knitted article forms the shape of straight tubulose at first substantially by means of expander and parallel rollers, is vertically cut in edge then, and is unfolded by means of the deployment rod of " V " type setting below branch's roller.Vertically the knitwear of cutting transmit via the system of spread rolls and work beam subsequently, and this system is arranged perpendicular to the direction of branch's roller and knitwear are extended to its whole width, and knitwear are drawn out and are wound on the coiling rod on its whole width.
At present, the cutting tubular knitted article and on whole width most of known machines of winding needle fabric all be to carry out work in mode according to EP0456576B1.Usually, parallel branch's roller is not driven, and they are freely installed in rotary manner and have roughly several centimetres gap between it, thereby can not produced undesirable folding so that do not extrude in the edge of straight tubular knitted article.Knitwear batch of material on the coiling rod is shelved on the driven roller by himself weight, and driven roller drives the coiling motion that knitwear are rotated.
Be that according to the shortcoming of the method for EP0456576B1 and machine work beam only is positioned at after the branch's roller and irrotational deployment rod that is driven, this need produce a large amount of power by work beam for pulling out knitwear, and also needs a large amount of spread rolls and work beam so that reach this power.Another shortcoming is to be wound on the rod of reeling and goes up the tension force that the knitwear of position are reeled and determine by the frictional force between take up roll and the knitwear parcel to a certain extent, this power increases along with the increase of package weight simultaneously, thereby the width of the knitwear of reeling reduces along with the increase of the diameter of parcel, and this is a kind of undesired effect.Another shortcoming is owing to the influence of indispensable friction during knitwear are via passive the pulling out of branch's roller and deployment rod, and knitwear do not limit exactly at its tension force from the knitting system pull-out location, and this quality to knitwear has a negative impact.
In addition, solution has been described in the announcement of EP0696658A1, wherein, tubular knitted article is pulled out by three driven work beams, below these three driven work beams, has cutting member in the centre of the width of straight tubular knitted article and at the equipment that has expansion equipment below the cutting member and be used for winding needle fabric on whole width.Yet this solution still can not prevent to produce in knitwear folding, as extruding knitwear edge between work beam.Another shortcoming also is big setting height(from bottom), therefore can not introduce this principle in practice.
The solution of describing during EP1335056A1 announces has been represented according to method more advanced among the EP0456576B1 and machine.Branch's roller has the gap between it, thereby can the extruded tubular knitwear and can in knitwear, not produce folding, at this driving branch's roller and because limited the holding of knitwear, branch's roller has produced the certain force of strain that acts on knitwear, by this tension force, branch's roller has reduced the influence that rubs on the deployment rod.Because gap between branch's roller and the relatively little angle that is held by knitwear, the pullout forces of branch's roller are failed enough big, so importantly after unwind roll, on whole width, use another work beam and have big holding.This has caused whole work beam and spread rolls system relative complex, and from the viewpoint of manufacturing cost and maintenance of machinery, this all has shortcoming.
The professional understands knitwear leave the part of spread rolls with whole width in fully owing to its asymmetric flexible edge that folded, and this has caused the diameter of knitwear batch of materials to increase on its edge and batch of material inhomogeneous.Therefore, in most actual solutions of using, directly before being wound up into batch of material, by compressed air stream this edge that trails.Constant air flow causes it to consume rising and has improved cost of investment and operating cost.And Here it is why the user often cut-out can cause the reason of the function that trails of above-mentioned shortcoming.
The objective of the invention is in order to eliminate or to reduce this area shortcoming in existing stage at least.
