Description
Technical field
The present invention relates to the support group of a kind of drafting system for textile machinery (Streckwerk)
it is with the support of two pilot tapes (F ü hrungsriemchen) for guiding the twin pressure roller (Druckwalzenzwilling) being wound around drafting system
with removable support bearing
and with the removable induction element for guiding fiber skein (Faserverband).The invention still further relates to the support bearing for support group and induction element.
Background technology
Known such support group from file DE 102 52 631 A1.Holding element is utilized directly to be fixed on support place with the induction element of pole form.The support bearing being called " spacing washer " in file DE 102 52 631A1 assembles (anbringen) at support place in the mode of separating with induction element.
In the owner of textile machinery, often there is such hope, that is, to older, the induction element at existing support group place retrofit (nachr ü sten).Because when induction element known from file DE 102 52 631 A1 is directly fixed on support, so recurrent, existing support does not allow this fixing of induction element.So must change whole support.The owner of replacing for textile machinery of support has higher transformation cost (Umbauaufwand), and in addition, compared to additionally buying induction element, this transformation cost explicit costs is higher.
Summary of the invention
The object of the invention is, improves support group, induction element and support bearing.
This object realizes by with under type, that is, make support bearing and induction element interfix in discerptible mode and be assemblied in support place.
Owing to making support bearing and induction element interfix, therefore in order to these two parts what be jointly assemblied in support place is fixedly only once needs.Can so design support bearing and induction element, that is, make this fixing feasibility existed at support place
enough.No longer need to change support when retrofiting to the induction element for main drawing zone (Hauptverzugszone) the middle guiding fiber skein at drafting system.Alternatively, can only traditional support bearing be assemblied in existing support place or the support bearing with induction element can be assemblied in existing support place.Thus, same existing support group can utilize less transformation cost and match from different requirements in the most suitable mode of cost.
Known a kind of support group from this type of file CN 201045153 Y non-, in this support group, induction element is connected with support bearing in inseparable mode.The direct injection moulding of induction element (anspritzen) is to support bearing place.Support bearing and induction element form all-in-one-piece component and no longer can change individually thus.In order to meet required support bearing and the modification be necessary of induction element diverse location, the different component of quite large quantity is necessary.But, in order to the drawing effect realizing optimizing is usually required, does not depend on the position of induction element and regulate A/F (Maulweite).In order to according to the whole combination of position meeting A/F and induction element in the embodiment of file CN 201045153 Y, the different parts of quite large quantity are necessary, and the owner of textile machinery stock must have all these parts.Equally when a large amount of different component (these parts are only slightly different), there is high confusion risk, thus there is this risk, that is, do not regulate all support groups of machine in an identical manner.Thus, the variable mass of the yarn produced.
Support group according to the present invention can be imagined two kinds of modification that how support bearing and induction element can be arranged in support place.In the first modification, support bearing is directly fixed on support place and induction element is fixed on support bearing place.In the second modification, induction element is directly fixed on support place and then support bearing is fixed on induction element place.These two kinds of modification all allow to use existing support and are the support bearing without induction element and the fixture (Befestigungsmittel) that designs originally.Thus, can continue without problems to use existing support.All favourable the producer of this owner for textile machinery and support group.The producer of support group can continue the instrument for the manufacture of support and the apparatus that use its past when not making a change.Only must replace existing support bearing.But support bearing is a kind of simple component, its cost is lower and its replacing means that not having larger transformation spends equally.When making machine mate with other fibrous material, frequent replaceable holder bearing.
By the discerptible replaceability of support bearing and induction element, each support group is only needed respectively a set of for regulating the induction element of the support bearing of different openings width and a set of different position with guide surface.After this combination of required support bearing and induction element can be assemblied in support place as requested.Thus, the diversity of parts keeps lower.Thus, the support bearing of the vicious size of error ground assembled belt or the risk of induction element equally can be quite low.Preferably, the identification of modification is guaranteed by painted mark.
Because induction element and support bearing are can the component of individual transaction, can be therefore induction element and support bearing requirement patent protection independent of support group.Induction element according to the present invention has the fixture for being connected with support bearing.Support bearing according to the present invention has the fixture for being connected with the induction element for fiber skein.Can realize thus, support bearing and induction element can interfix.Induction element or support bearing have the fixture for being connected with support.Fixture for being connected with support matches with the fixture existed at support place.Advantageously, kayser all anchor designs is become to connect (Schnappverbindung).Preferably, kayser connection is formed at the protuberance of the pin shape (zapfenartig) at a parts place and the relevant recess at another parts place by least one.Thus, all parts quite easily can be clamped mutually (klipsen) and can again be separated from each other without problems equally.
Be arranged in favourable design of the present invention, support bearing and induction element have at least one bearing-surface respectively for directly abutting in support place.The bearing-surface directly abutting in support place directly ensures locating quite accurately of support bearing and induction element by support.Although support bearing and induction element interfix, the site error that the change of in two parts is large can not be there is due to the addition of manufacturing tolerance.Support bearing and induction element as far as possible directly located by support by bearing-surface independently of one another.Make the adjustability of separating of support bearing and induction element and goodish accuracy in quite favourable mode and be combined with each other in simply remodeling property at existing support place.
Be arranged in other favourable design, the guide surface for fiber skein at induction element place is by bar, pref. cylindrical bar and being formed.Preferably, induction element has keeper, is furnished with fixture at this keeper place.Keeper directly can be injected into the bar place comprising guide surface.In support bearing advantageously, in support bearing, be provided with the recess with the region of bearing-surface for induction element.
