Definitions
- the invention relates to an automatic winder Thermal splicers according to the preamble of claim 1.
- the splicing air provided to the splicing devices via the compressed air network of a textile machine, for example an automatic winder, is therefore heated in a heat source, for example an air heater, before it enters the splicing head of the splicer, to such an extent that it reaches the optimum temperature for the material to be processed having.
- a heat source for example an air heater
- the splice air can have a temperature between approximately 50 degrees Celsius and 150 degrees Celsius when it enters the splice channel of a so-called thermal splicer, depending on the type of fiber present.
- Thermal splicer known in which the required in the splice channel Compressed air first in an upstream heat exchanger is heated.
- Splice channel opening nozzle opening another heat source installed the temperature of the incoming air jet increased to at least 50 degrees Celsius.
- a similar thermal splicer is also in DE 35 28 619 C2 described.
- this known device too Heat source for the treatment of the splice air and another Heat source provided for preheating the splice head.
- this known thermal splicer has one Temperature sensor in conjunction with a appropriate control device ensures that the Temperature in the area of the splice head within a specified Limits remain.
- a thermal splicer is known from DE 39 24 827 A1, in which the heat source arranged in the region of the splice head is formed by a PTC thermistor element.
- PTC thermistor elements are self-regulating due to their PTC effect. This means that with such thermal splicers, a constant temperature is ensured in the area of the splice head.
- thermal splicers described above each have devices for heating the splice head and devices for heating the supplied splice air; the known thermal splicers, however, do not have any facilities for cooling the thermal splicer, especially the splice head, to a lower working temperature. This means that when changing the batch, in which the subsequent batch of yarn requires a lower splicing temperature, there are waiting times and thus loss of productivity.
- the Invention the task of ensuring that in If necessary, for example when changing lots, one Acceleration of the cooling process of the thermal splicer, in particular an automatic winder is possible.
- the embodiment of the invention has in particular the Advantage that a cross-winder so equipped also in the event of a lot change, in which a lowering of the Temperature of the thermal splicer is necessary, already after is ready for use again in the shortest possible time, so that waiting times largely avoided and almost the same when changing lots inevitable loss of efficiency of the textile machine can be minimized.
- the job computers of the individual Software jobs are designed so that the Thermal splicer if necessary, for example one Batch change, defined with compressed air from the compressed air network of the textile machine and thus the thermal splicer can be cooled faster.
- the splice air valves assigned to the thermal splicers are acted upon by additional switch-on pulses from the workstation computer in the sense of "opening". Via the open splice air valves, the relatively cool compressed air in the compressed air network of the textile machine reaches the heated zones of the thermal splicer, in particular in the area of the splice channel, which leads to a significant acceleration of the cooling process.
- the splice air valves are preferably individual Thermosplitter of the multitude of jobs in the Textile machine can be controlled successively and alternately, see above that only a relatively small part of this Splice air valves is open at the same time (claim 3).
- the thermal splicer 1 has a base body 2, on which a splice head 5 is fixed by means of a screw bolt 3. As indicated in FIG. 2, a plate 4 can be connected between the base body 2 and the splice head 5. As can be seen in particular from FIG. 2, a splice air channel 6 is incorporated into the base body 2 and is connected to a corresponding splice air channel 8 in the splice head 5 via a connection channel 7. The connection channel 7 thereby passes through a bore in the plate 4 and a heating element 45 arranged in the region of the splice head 5.
- Two splice air nozzles 9 and 10 lead from the splice air channel 8 in the splice head 5 into a splice chamber 11 which is designed as a splice channel and which can be closed, for example, by a cover 12.
- Bores 13, 14 are also arranged in the base body 2, in the pneumatically working holding and Preparation devices 15 and 16, respectively are.
- These holding and preparation devices 15, 16 either have a one-piece processing tube or are, as indicated in the exemplary embodiment in FIG. 2, as two-part machining elements. In one The case is the processing tubes 17 or 18 one pipe attachment 19 or 20 connected upstream.
- flow into the Processing tubes 17, 18 of the holding and Preparation devices 15, 16 each have injector bores 25 or 26, which via ring channels 23 or 24 connected to pneumatic lines 27 and 28, respectively are.
- the pneumatic lines 27, 28 are in turn over Valves, preferably 2/2-way valves 29 or 30, and a pneumatic line 34 into which a heat source 31 is switched on to the pneumatic network 35 of the textile machine and thus connected to an overpressure source 36.
- the 2/2-way valves 29, 30 are also over Control lines 37 and 39 with the Job computer 40 of the job in question connected and can be controlled by it in a defined manner.
- the splice air duct 6 in the base body 2 of the thermal splicer 1 is also connected to the pneumatic network 35 of the textile machine.
- a pneumatic line 33 into which a splice air valve 32, preferably a 2/2-way valve, is switched on, is connected to the pneumatic network 35 of the textile machine via the aforementioned pneumatic line 34.
- a first Heat source 31 which the splice air up to 150 degrees Celsius can heat in the area of the splice head 5 of the Thermal splicer 1 provided a further heating element 45, the the temperature of the splice head to a predetermined level lifts what with different types of yarn especially at the beginning of the rewinding process, i.e. the first one to occur Splice connections is very important.
- the software of the workstation computer 40 is according to the invention designed so that the splice air valve 32 not only in Relation to regular thread joining operations can be activated, but if necessary, for example at a lot change, can also be controlled to the splice head 5 to act with cool compressed air from the compressed air network 35 and thus accelerates the temperature of the splice head 5 lower.
- the heat source 31 and the heating element 45 are first generated via the workstation computer 40 off.
- a switch-on pulse i is then sent to the splice air valve 32 via the control line 38 from the workstation computer 40 and initiates an opening of this splice air valve 32.
- This cool compressed air is fed into the splice chamber 11 of the splicing head 5 via the bore 8 and the splice air nozzles 9, 10 blown in and cools the splice head 5 effectively. Since the opening time of the splice air valve 32 is only relatively short, the cooling process is preferably repeated a few times. This means that the thermal splicers of the affected workstations are alternately supplied with cooling air.

Abstract
Description
Das heißt, die Spleißluft kann bei ihrem Eintritt in den Spleißkanal eines sogenannten Thermospleißers, abhängig von der vorliegenden Faserart, eine Temperatur zwischen circa 50 Grad Celsius und 150 Grad Celsius aufweisen.
Das heißt, bei derartigen Thermospleißern wird auf einfache Weise für eine Temperaturkonstanz im Bereich des Spleißkopfes gesorgt.
Das heißt, bei einem Partiewechsel, bei dem die nachfolgende Garnpartie eine niedrigere Spleißtemperatur erfordert, fallen Wartezeiten und damit Produktivitätsverluste an.
Über die geöffneten Spleißluftventile gelangt die im Druckluftnetz der Textilmaschine befindliche, relativ kühle Druckluft in die erwärmten Zonen des Thermospleißers, insbesondere in den Bereich des Spleißkanals, was zu einer deutlichen Beschleunigung des Abkühlprozesses führt.
- Fig. 1
- einen an einen Arbeitsstellenrechner angeschlossenen Thermospleißer, in Vorderansicht,
- Fig. 2
- eine Seitenansicht eines im Schnitt dargestellten, durch einen Arbeitsstellenrechner ansteuerbaren Thermospleißer sowie schematisch die dem Thermospleißer zugeordneten Versorgungs- und Steuereinrichtungen.
Wie insbesondere aus Figur 2 ersichtlich, ist in den Grundkörper 2 ein Spleißluftkanal 6 eingearbeitet, der mit einem entsprechenden Spleißluftkanal 8 im Spleißkopf 5 über einen Anschlußkanal 7 verbunden ist. Der Anschlußkanal 7 durchfaßt dabei eine Bohrung in der Platte 4 sowie ein im Bereich des Spleißkopfes 5 angeordnetes Heizelement 45.
Vom Spleißluftkanal 8 im Spleißkopf 5 führen zwei Spleißluftdüsen 9 und 10 in eine als Spleißkanal ausgebildete Spleißkammer 11, die zum Beispiel durch einen Deckel 12 verschließbar ist.
Das heißt, eine Pneumatikleitung 33, in die ein Spleißluftventil 32, vorzugsweise ein 2/2-Wegeventil, eingeschaltet ist, steht über die vorgenannte Pneumatikleitung 34 mit dem Pneumatiknetz 35 der Textilmaschine in Verbindung.
Das heißt, über die Pneumatikleitungen 33, 34 gelangt aus dem Druckluftnetz 35 der Textilmaschine kühle Druckluft in die Bohrung 6 des Grundkörpers 2 des Thermospleißers 1. Diese kühle Druckluft wird über die Bohrung 8 sowie die Spleißluftdüsen 9, 10 in die Spleißkammer 11 des Spleißkopfes 5 eingeblasen und kühlt dabei den Spleißkopf 5 wirkungsvoll. Da die Öffnungszeit des Spleißluftventiles 32 jeweils nur relativ kurz ist, wird der Kühlvorgang vorzugsweise einige Male wiederholt.
Das heißt, die Thermospleißer der betroffenen Arbeitsstellen werden nacheinander, wechselweise mit Kühlluft beaufschlagt.
