Description
Technical field
The present invention relates to a kind of heater that is used for heated yarn by claim 1 preamble.
Background technology
For example by the heater of known this type of DE 29 33 087A1.
Known long filament heats by means of heater in coiling deformation devices in order to make synthetic thread Texturized, so that Texturized and stretch and carry out shrink process.Here develop different heaters according to the difference of treatment step, they heat long filament in various processes best.For example, require long filament to pass heater in the de-stress effect that obtains during the shrink process on the high long filament as far as possible unstressedly.For this treatment step, a kind of like this heater has obtained special checking, and the long filament and the area of heating surface are advanced in contact in this heater, for example by known to the DE 2933087A1.Here long filament passes a heat tunnel from external heat.Adopt heat-carrying agent as heating agent, it produces the heat that requires on the heat tunnel outer wall owing to condensation.In such heater such problem can appear in principle.That is, owing to form stack effect within the heat tunnel between the upright position of the heater that the circulation of heat carrier forms exports common long filament below and top long filament enters the mouth.In order to obtain as far as possible little stack effect in heat tunnel, the flow cross of heat tunnel is selected greatly as far as possible.The oil agent steam that brings thus, give out from long filament directly enters heater and causes the shortcoming of deposition to solve by such method known heater,, produces a flushing air-flow in heat tunnel that is.Purge gas stream produces by an input unit, and introduces heat tunnel by many nozzle bores on the heat tunnel lid.But can not deal with problems thus, make the guiding of the long filament that in the wide flow cross of heat tunnel, guides particularly when noncontact is led, become problem unstressedly, need a lot of heat energy for the purpose heat tunnel that heats on the other hand.
When crimped filament distortion and stretching, preferably adopt for example by the heater known to the EP 0994206A1.Texturized and when stretching during heating the long filament band very big thread-tension and advance.At this moment long filament has the intrinsic power by Texturized generation, therefore the long filament guiding is proposed high requirement.This heater is preferably made so-called high temperature heater (HTH), and here long filament guides by fiber guiding element with a certain distance from the area of heating surface.Preferably by the resistive element heating, the area of heating surface has the temperature above the filamentary material fusion temperature to the area of heating surface here.Therefore require long filament to keep with a certain distance from the area of heating surface.This known heater has an insurance system for the situation of filament breakage, wherein produces an air-flow when filament breakage in heat tunnel, and it prevents the long filament that ruptures and the contact between the area of heating surface.This system has very big shortcoming, that is, the triggering of air input realizes according to filament breakage.Because the measured response time, pulling of long filament short time taken place before air-flow enters heat tunnel unavoidably, therefore be difficult to prevent with heat is surperficial contact.
Summary of the invention
The objective of the invention is now, improve such heater in this wise, that is, do not rely on the position and the type of heater, in heat tunnel, possesses an environment that is complementary with long filament respectively, to reach long filament rapidly and the guiding of uniform heating and/or long filament the best.
Another object of the present invention is, a kind of heater of this type is provided, and can change the long filament guiding and long filament heats by the device that can control easily during with this heater.
This purpose solves by such method, promptly, in heat tunnel, establish a heating insert that is used for guiding long filament, this heating insert comprises an air duct system, it is connected with the pressure source of air input unit by a pipeline, and on heating insert the formation jet hole and with the air duct system connectivity.
The present invention is based upon on the basis of such understanding, that is, the air-flow that produces in heat tunnel has the important effect that helps long filament heating and/or long filament guiding.Therefore the present invention produces an artificial airflow in heat tunnel, stops possible heat loss.For example can directly control the environment of long filament by the jet hole of heating insert.Particularly in heat tunnel, can produce the artificial airflow of for example offsetting undesirable big chimney draft.Another advantage by heater of the present invention is by the artificial air-flow that produces in heat tunnel, to reduce and dissolve rapidly the air that comes from the outside of bringing heat tunnel by long filament into.Reach the preheating of the artificial airflow that enters heat tunnel by the air duct system that is integrated in the heating insert in addition, thereby improve all even rapid heating of long filament in heat tunnel.Change by the artificial airflow in heat tunnel can make the condition in the heat tunnel mate individually with filament types arbitrarily.For example, can in heat tunnel, adjust to a correspondingly little artificial airflow, obtaining the positive effect of air-flow, and not form big heat loss for the long filament of little number.By the jet hole of processing on heating insert, more weak artificial airflow just can have been controlled the surrounding environment of the long filament of directly advancing on heating insert.
The good improvement structure of the present invention is determined by the feature and the feature combination of dependent claims.
Be made of moulding orbit according to a kind of good improvement structure heating insert of the present invention, wherein jet hole is made in the zone of the spigot surface that the long filament of moulding orbit advances on it, and with air duct system connectivity in moulding orbit.Thereby can irrespectively adjust the long filament route of the safety in the heat tunnel with the type of heater.
According to the difference for long filament desirable environment requirement in heater, the jet hole on the heating insert can be provided with dispersedly along the long filament stroke that leads, and perhaps is positioned in long filament inlet region or the long filament outlet area.Dividing timing not only to change the long filament guiding but also change the continuous direct influence that long filament heats to the long filament generation along long filament guiding stroke.The ambient air stream that can control chimney draft especially or bring in the time of in the jet hole part is arranged on the long filament inlet region or in the long filament outlet area.
According to a kind of particularly preferred improvement structure of the present invention, jet hole be arranged on the contacted spigot surface of long filament zone in.Can particularly reduce thus by the long filament friction that causes that contacts between long filament and the spigot surface.Can between long filament and spigot surface, produce one by the adjustment artificial airflow like this and help the air cushion that long filament leads.Therefore long filament can rub and heat tinily.
But in order to reach special effect, according to the another kind of good improvement structure of the present invention, jet hole can be done to such an extent that have one against the inclination angle of long filament route or have a tendency along the long filament route on spigot surface.So for example can on long filament, produce the conveying effect by a jet hole that tilts along the long filament route.Particularly before beginning, process when the long filament repiece, can advantageously utilize this effect.Therefore the pressure source that is connected in the air duct system by adjustment can produce the special big artificial airflow that is used for the long filament repiece.When operation long filament pressure source can be with the pressure operation of correspondingly adjusting smallerly between the period of heating in heat tunnel, make the less artificial airflow of generation in heat tunnel.
For make long filament directly by with the spigot surface Contact Heating, moulding orbit is preferably done with a seal wire groove that extends on heat tunnel, wherein spigot surface is made of the bottom land of seal wire groove.
But such do have a seal wire groove moulding orbit also can be used for the non-contacting basically heating of long filament.Here spigot surface is made of the groove section of the weak point of the many projections in the seal wire groove.The groove section is distributed on the length of seal wire groove.
In order to clean spigot surface, heating insert preferably is fixed in the heat tunnel replaceably.Here can on diverse location, load onto for example additional director element on the heating insert selectively, the silk thread guiding is carried out with the flexible way method.

The specific embodiment
Schematically illustrate first kind of embodiment by heater of the present invention among Fig. 1, it for example can be used in the coiling deformation devices, so that heat Texturized long filament in the shrinking zone, handles to carry out stress.Expression is looked by the cross-sectional of embodiment of heater of the present invention among Fig. 2, and following explanation if specifically do not indicate at some figures, so just all is suitable for two figures.
The heat tunnel 1 that has the length of a band wall 3 by the embodiment of heater of the present invention.Heat tunnel 1 with wall 3 is made of the light-wall pipe with rectangular cross section in the present embodiment.Heat tunnel 1 opens to end face.The heating insert 5 of a moulding orbit 9 forms of in heat tunnel 1, packing into.Shaping track 9 has a cannelure 10, and it extends along the whole distance of heat tunnel 1.Heating insert 5 is placed directly on the wall 3 of heat tunnel 1 with the longitudinal side on cannelure 10 opposites.Here the contact between the wall 3 of moulding orbit 9 and heat tunnel 1 is designed to like this, and heat can be transmitted on the moulding orbit 9 from wall 3.Cannelure 10 in the moulding orbit 9 has a spigot surface 11 on bottom land, long filament 6 is advanced on it in contact.The spigot surface 11 that is made of the bottom land of cannelure 10 is done along the long filament direct of travel to be crooked, to pass heat tunnel 1 with making long filament circular arc, the long filaments outlet 8 from the long filament inlet 7 of an end to the other end.In the moulding orbit 9 inner air duct systems 15 that form.Air duct system 15 is communicated with the jet hole 16 of many feeding spigot surfaces 11.Jet hole 16 is arranged on the spigot surface 11 along heating distance space certain distance with forming a line.Here jet hole 16 has an inclination angle against long filament direct of travel layout.The air duct system 15 of moulding orbit 9 inside is connected with the pressure source 13 of air input unit 12 by a pipeline 14 on an end face of moulding orbit 9.
But heating unit also can be made of electric device, with heating heat tunnel 1.
For the Temperature Treatment of long filament 6, it passes heat tunnel 1 through long filament inlet 7 and long filament outlet 8.Long filament inlet 7 sets an inlet thread guide 18 for this reason, and long filament outlet 8 sets an outlet thread guide 17.Here the thread guide 18 that enters the mouth is provided with like this with outlet thread guide 17, makes long filament 6 pass heat tunnel 1 in contact in the cannelure 10 of moulding orbit 9 basically.Wherein directly flow to heat tunnel 1 from the wall 3 of heating unit 2 by heat tunnel 1 for heated yarn 6 energy needed.The wall 3 of heat tunnel 1 is preferably made by the material that very high capacity of heat transmission is arranged for this reason.Thereby the energy that passes on the wall 3 from heating unit 2 can not have directly input heat tunnel 1 of big loss ground.For unallowed contact between the wall 3 of avoiding long filament 6 and heat tunnel 1 when the contact ground guiding long filament 6, moulding orbit 9 one ends are fixed in the heat tunnel 1.Long filament 6 is advanced on the cannelure 10 inner faces 11 of moulding orbit 9.Moulding orbit 9 has wearing face at least on the spigot surface 11 of cannelure 12.Import moulding orbit 9 by heat into from wall 3 and reach the additional Contact Heating of long filament 6 in cannelure 10.
