Description
Die vorliegende Erfindung betrifft ein Spleissgerät zur Verspleissung von Garn sowie ein Verfahren zum Herstellen eines Spleissgeräts.The present invention relates to a splicer for splicing yarn and a method for producing a splicer.
Aus dem Stand der Technik sind Spleissgeräte bekannt. Spleissgeräte werden üblicherweise verwendet zum Verbinden von Fäden, Garn oder ähnlichen Materialien. Bei Druckluftspleissgeräten wird Druckluft auf das Garn, insbesondere auf die Enden des Garns aufgebracht, um diese zu verwirbeln, wodurch sich die Filamente der Garne trennen, sich miteinander verhaken und verknoten. Dadurch lassen sich Garne leicht verbinden.Splicing devices are known from the prior art. Splicers are commonly used to join threads, yarn or similar materials. In compressed air splicers, compressed air is applied to the yarn, in particular to the ends of the yarn, in order to swirl them, as a result of which the filaments of the yarn separate, become entangled and knotted together. This makes it easy to combine yarns.

Leitungselemente münden nur an der Gehäusehülle, wenn die Funktion des Spleissgeräts dies erfordert. Leitungselemente, die nicht an der Gehäusehülle münden, werden hier Innenleitungselemente genannt.

Die Spleisskammer kann am oder im Spleisskopf angeordnet sein. Der Spleisskopf kann Schneidelemente, insbesondere Messer, zum Schneiden von Garn umfassen. Durch solche Schneidelemente lassen sich die Garne einfach bearbeiten. Der Spleisskopf kann Klemmelemente, insbesondere öffenbare Klemmelemente, umfassen. Durch Klemmelemente wird auf einfache Art sichergestellt, dass die Garne in der Spleisskammer bleiben.The splice chamber can be arranged on or in the splice head. The splicing head can comprise cutting elements, in particular knives, for cutting yarn. The yarns can be easily processed by such cutting elements. The splicing head can comprise clamping elements, in particular opening clamping elements. Clamping elements ensure in a simple manner that the yarns remain in the splice chamber.
Die Spleisskammer kann mit mindestens einem Leitungselement einstückig verbunden sein.The splice chamber can be connected in one piece to at least one line element.
Sind Spleisskammer und Leitungselemente einstückig verbunden, ist der Druckverlust gering.If the splice chamber and line elements are connected in one piece, the pressure loss is low.
Das Spleissgerät kann mindestens ein Schaltelement, insbesondere einen Schalter zum Betätigen eines Ventils zum Starten des Verspleissungsprozesses umfassen.The splicer can comprise at least one switching element, in particular a switch for actuating a valve to start the splicing process.
Durch ein Schaltelement lässt sich der Fluiddurchfluss ein- oder ausschalten. Bevorzugt ist das Schaltelement mit einem Steuerungselement verbunden oder verbindbar und ist dazu ausgelegt, das Steuerelement, insbesondere mechanisch, zu betätigen. Bevorzugt ist das Schaltelement ein mechanisches Schaltelement, insbesondere bevorzugt ein mechanischer Schalter.The fluid flow can be switched on or off by a switching element. The switching element is preferably connected or connectable to a control element and is designed to actuate the control element, in particular mechanically. The switching element is preferably a mechanical switching element, particularly preferably a mechanical switch.
Dadurch kann der Benutzer das Gerät einfach bedienen. Insbesondere weist das Spleissgerät ausschliesslich rein mechanische und/oder pneumatische und/oder hydraulische Elemente auf, d.h. es sind keine elektrischen oder elektronischen Bestandteile nötig. Das ermöglicht einen einfachen Aufbau des Spleissgeräts. Ein Schaltelement kann drehbar, kippbar, drückbar oder ziehbar sein.This allows the user to easily operate the device. In particular, the splicer has purely mechanical and / or pneumatic and / or hydraulic elements, i.e. no electrical or electronic components are necessary. This enables the splicer to be set up easily. A switching element can be rotatable, tiltable, pushable or pullable.
Das Spleissgerät kann mindestens ein Regulierungselement zum Regulieren des Fluiddurchflusses, insbesondere zum Regulieren des Fluiddurchflusses durch einen Benutzer, umfassen.The splicing device can comprise at least one regulating element for regulating the fluid flow, in particular for regulating the fluid flow by a user.
Bevorzugt umfasst das Regulierelement ein Zeitschaltelement, insbesondere ein Ventil. Bevorzugt ist das Zeitschaltelement ein Ventil mit Luftkammer zum Ein-und/oder Ausschalten des Fluiddurchflusses. Der Fluiddurchfluss führt insbesondere vom Druckluftzufuhrelement zu einem Aktorelement, insbesondere bevorzugt einer an der Spleisskammer mündenden Luftzufuhröffnung.The regulating element preferably comprises a time switching element, in particular a valve. The timer element is preferably a valve with an air chamber for switching the fluid flow on and / or off. The fluid flow leads in particular from the compressed air supply element to an actuator element, particularly preferably an air supply opening opening at the splice chamber.
Bei einem Spleissprozess können verschiedene Ventile nacheinander betätigt werden, wodurch zuerst ein oder mehrere Aktorelemente, z.B. Klappe und Messer, betätigt und dann weitere Aktorelemente, wie eine Luftzufuhröffnung in der Spleisskammer, aktiviert werden. Die Dauer dieser gesteuerten Sequenz kann durch das Regulierelement geändert werden, in dem der Durchfluss des Fluids verstärkt oder vermindert wird. Durch ein Zeitschaltelement kann der Fluiddurchfluss automatisch eingeschaltet werden, wenn die Spleisskammer abgedichtet ist und/oder abgeschaltet werden, wenn eine bestimmte Zeit vergangen ist. So kann beispielsweise sichergestellt werden, dass die Druckluftpatrone weniger schnell geleert wird. Durch ein solches Regulierelement ist es möglich, für Fäden mit unterschiedlichen Fasern verschieden lange Verspleissprozesse durchzuführen. Für brüchige Fasern ist es beispielsweise nötig, schonender zu verspleissen, als für andere, stabilere Fasern. Das Regulierelement kann stufenlos und/oder stufenweise reguliert werden. Stufenlose Regulierung ermöglicht ein feines Anpassen der Strömung. Bei einer stufenweisen Regulierung sind für bekannte Garne die benötigten Einstellungen einfach einzustellen. Das Regulierungselement kann ein Drehelement umfassen. Dadurch ist eine Regulierung einfach und schnell möglich. Das Regulierungselement kann lösbar oder fest mit dem Spleissgerät verbunden oder verbindbar sein.In a splicing process, different valves can be actuated one after the other, whereby one or more actuator elements, for example flap and knife, are actuated first and then further actuator elements, such as an air supply opening in the splice chamber, are activated. The duration of this controlled sequence can be changed by the regulator by increasing or decreasing the flow of the fluid. The fluid flow can be automatically switched on by a time switching element when the splice chamber is sealed and / or switched off when a certain time has passed. This can ensure, for example, that the compressed air cartridge is emptied less quickly. Such a regulating element makes it possible to use different threads for different fibers perform long splicing processes. For example, brittle fibers need to be spliced more gently than other, more stable fibers. The regulating element can be regulated continuously and / or in stages. Stepless regulation enables a fine adjustment of the flow. With step-by-step regulation, the settings required for known yarns are easy to set. The regulating element can comprise a rotary element. This makes regulation quick and easy. The regulating element can be detachably or firmly connected or connectable to the splicer.
Das Spleissgerät kann ein Anzeigeelement zum Anzeigen einer Statusinformation, insbesondere die Durchflussstärke durch das Regulierungselement, umfassen.The splicer can comprise a display element for displaying status information, in particular the flow rate through the regulating element.
Ein solches Anzeigeelement kann die Stufen des Regulierelements anzeigen. Dies vereinfacht die Bedienung des Spleissgeräts.Such a display element can display the levels of the regulating element. This simplifies the operation of the splicer.
Mindestens ein Leitungselement kann mit einem Druckluftzufuhrelement und/oder einer Spleisskammer und/oder einer Düse einstückig gefertigt sein.At least one line element can be made in one piece with a compressed air supply element and / or a splice chamber and / or a nozzle.
Dadurch kann ein kompakter und dichter Aufbau des Spleissgeräts ermöglicht werden.This allows a compact and dense construction of the splicer.
Das Spleissgerät, insbesondere der Ventilblock des Spleissgeräts, kann mindestens teilweise durch ein additives Verfahren hergestellt werden. Das additive Fertigungsverfahren kann ein Schmelzschichtungsverfahren, insbesondre Fused-Depostion-Modeling-Verfahren (FDM), ein Selektives-Lasersinter-Verfahren (SLS) oder ein Multi-Jet-Fusion-Verfahren (MJP) sein.
Das ermöglicht eine einfache und effiziente Fertigung komplexer Strukturen.The splicer, in particular the valve block of the splicer, can be manufactured at least partially by an additive method. The additive manufacturing process can be a melt layer process, in particular fused deposition modeling process (FDM), a selective laser sintering process (SLS) or a multi-jet fusion process (MJP).
This enables simple and efficient production of complex structures.
Die Aufgabe wird weiterhin durch ein Verfahren zum Herstellen eines Spleissgeräts gelöst. Beim Verfahren zum Herstellen eines Spleissgeräts wird ein Ventilblockgehäuse mit mindestens einem Leitungselement einstückig gefertigt, insbesondere in einem additiven Fertigungsverfahren hergestellt.The object is further achieved by a method for producing a splicer. In the method for producing a splicer, a valve block housing with at least one line element is manufactured in one piece, in particular in an additive manufacturing method.
Dadurch kann ein kompaktes Spleissgerät schnell und einfach hergestellt werden. Das Leitungselement kann durchgehend im Innenraum des Ventilblockgehäuses angeordnet sein. Das Leitungselement kann zumindest teilweise krumm oder mit einem Bogenabschnitt gefertigt sein. Bei der Herstellung kann mindestens ein Aussenleitungselement mit mindestens einem Innenleitungselement und/oder mit einer Düse und/oder einer Spleisskammer einstückig gefertigt werden.This enables a compact splicer to be manufactured quickly and easily. The line element can be arranged continuously in the interior of the valve block housing. The line element can be made at least partially curved or with an arc section. During manufacture, at least one outer line element with at least one inner line element and / or with a nozzle and / or a splice chamber can be manufactured in one piece.
Dadurch erfolgt die Herstellung einfach und das Spleissgerät ist besonders dicht, da es keine Übergänge zwischen den einzelnen Komponenten des Geräts gibt, die abgedichtet werden müssen.
Es können Steuer- und/oder Regulierelemente und/oder andere Elemente wie Schrauben in das Spleissgerät eingesetzt werden. Diese eingesetzten Elemente können fest oder lösbar mit dem Ventilblockgehäuse verbunden werden. Das Ventilblockgehäuse kann in ein Aussengehäuse eingesetzt werden. Das Aussengehäuse kann spritzgegossen werden. Ein Spleisskopf kann mit dem Ventilblockgehäuse fest oder lösbar verbunden werden. Eine Spleisskammer kann mit einem Leitungselement fest oder lösbar verbunden werden.This makes the production simple and the splicer is particularly tight, since there are no transitions between the individual components of the device that need to be sealed.
Control and / or regulating elements and / or other elements such as screws can be inserted into the splicer. These elements used can be fixed or detachably connected to the valve block housing. The valve block housing can be inserted into an outer housing. The outer housing can be injection molded. A splice head can be fixed or detachably connected to the valve block housing. A splice chamber can be connected to a line element in a fixed or detachable manner.
