Abstract
Description
Die Erfindung betrifft eine zur Gattung der Mehrkopfstickmaschinen gehörende Stickmaschine nach dem Oberbegriff des Anspruches 1.The invention relates to a belonging to the type of multi-head embroidery embroidery machine according to the preamble of claim 1.
Bei den industriell genutzten Stickmaschinen gibt es im Wesentlichen zwei Maschinentypen, nämlich Schiffchenstickmaschinen mit horizontal bewegbaren Nadeln zur Bearbeitung großflächiger, langgestreckter Stoffbahnstücke und endloser Stoffbahnen, und Mehrkopfstickmaschinen mit vertikal bewegbaren Nadeln, wobei diese Maschinen auch als Greiferstickmaschinen bezeichnet werden. Sie dienen zum Bearbeiten von Stoffzuschnitten oder auch dem gleichzeitigen Besticken mehrerer kleiner Stoffeinzelteile (Siehe
Aus der
Der Aufbau eines Maschinengestells aus zwei nur an ihren beiden Enden gehaltenen Tragbalken ermöglicht zwar eine verhältnismäßig einfache Bauweise, jedoch neigt ein solcherart aufgebautes Maschinengestell prinzipiell zu resonanzbedingten Schwingungen, die von schwingend oder intermittierend angetriebenen Bauteilen und hierbei insbesondere von den auf- und abbewegten Nadelstangen der Stickköpfe angeregt werden. Solche resonanzbedingten Schwingungen sind um so stärker, je länger der Portalträger ausgebildet und je höher die Drehzahl ist, mit der die Stickmaschine betrieben wird. Aufgrunddessen sind einer Vergrößerung der Anzahl der Stickköpfe und der damit zusammenhängenden Verlängerung des Maschinengestells sowie auch der Erhöhung der Maschinendrehzahl Grenzen gesetzt.Although the construction of a machine frame of two support beams held only at its two ends allows a relatively simple design, such a machine frame constructed in principle tends to resonance oscillations caused by swinging or intermittently driven components and in particular by the up and down moved needle bars of the embroidery heads animated become. Such resonance-induced vibrations are stronger, the longer the gantry support is formed and the higher the speed at which the embroidery machine is operated. Due to this, an increase in the number of embroidery heads and the associated extension of the machine frame as well as the increase in the engine speed limits.
Es hat bereits zahlreiche Versuche zur Reduzierung der Schwingungsneigung von Stickmaschinen gegeben. So werden z. B. in der vorstehend genannten
Neben einer Vergrößerung der Leistung der Mehrkopfstickmaschinen wäre es wünschenswert, wenn ihr Einsatzgebiet dahingehend erweitert werden könnte, dass auch längere Stoffzuschnitte oder sogar endlose Stoffbahnen bestickt werden können. Auch diesbezüglich hat es schon entsprechende Versuche gegeben. So ist bereits vorgeschlagen worden, Mehrkopfstickmaschinen, ähnlich wie in der
Der Erfindung liegt daher die Aufgabe zugrunde, eine Mehrkopfstickmaschine zu schaffen, bei der zum einen die Maschinenleistung erhöht und zum anderen die Einsatzmöglichkeit hinsichtlich unterschiedlicher Stickarbeiten vergrößert werden kann. Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The invention is therefore an object of the invention to provide a multi-head embroidery machine, in which on the one hand increases the machine performance and on the other hand, the possible use can be increased in terms of different embroidery work. The object is solved by the characterizing features of claim 1.
Da die als Stütz- und Tragelemente für die Tragbalken dienenden, brückenartig ausgebildeten Halterahmen nicht wie die herkömmlichen Stützpfeiler in der vertikalen Ebene der beiden Tragbalken liegen, sondern quer hierzu verlaufen, müssen sie nicht wie die besagten Stützpfeiler an den Enden der Tragbalken angeordnet werden, sondern können an beliebiger Stelle mit den Tragbalken verbunden sein. Da es also möglich ist, die Halterahmen mit Abstand zu den Enden der Tragbalken anzuordnen, kann somit bei gegebener und unveränderter Länge der Tragbalken mit nur zwei an geeigneter Stelle mit den Tragbalken verbundenen Halterahmen bereits ein schwingungsarmes Maschinengestell geschaffen werden. In gleicher Weise kann durch Hinzufügen weiterer Halterahmen das Maschinengestell zusätzlich versteift werden, so dass entweder die Schwingungsneigung des Maschinengestells noch weiter verringerbar ist oder die Möglichkeit geschaffen wird, die Drehzahl der Maschine zu erhöhen. Eine andere Möglichkeit die Maschinenleistung zu vergrößern, besteht darin, unter Verwendung zusätzlicher Halterahmen die Tragbalken zu verlängern, um die Stickmaschine mit weiteren Stickköpfen versehen und folglich ein größeres Stickfeld bearbeiten zu können.Since serving as support and support elements for the support beams, bridge-like support frame do not lie like the conventional buttresses in the vertical plane of the two support beams, but run transversely thereto, they do not have to be arranged as said support pillars at the ends of the support beams, but can be connected at any point with the stringers. Since it is thus possible to arrange the holding frame at a distance from the ends of the supporting beams, a vibration-free machine frame can thus already be created with a given and unchanged length of the supporting beams with only two holding frames connected to the supporting beams at a suitable location. In the same way, the machine frame can be additionally stiffened by adding further holding frame, so that either the vibration tendency of the machine frame is further reduced or the possibility is created to increase the speed of the machine. Another way to increase machine performance is to extend the support beams using additional support frames to provide the embroidery machine with additional embroidery heads and thus to be able to machine a larger embroidery field.
Durch die Querausrichtung der brückenförmigen Halterahmen und ihre in Querrichtung gemessene große lichte Weite weist das Maschinengestell einen in Längsrichtung verlaufenden freien Durchgangsraum auf. Dieser ermöglicht es, dass erstmals bei Mehrkopfstickmaschinen endlose Stoffbahnen in Längsrichtung völlig unbehindert durch die Maschine hindurchbewegt und bearbeitet werden können. Wenn im Vergleich dazu bei herkömmlichen Mehrkopfstickmaschinen, bei denen der obere und der untere Tragbalken an zwei endseitig angeordneten Stützpfeilern befestigt sind, endlose Stoffbahnen bearbeitet würden, so würden die Stützpfeiler der Zuführung und Wegführung der Stoffbahnen zum bzw. vom Stickrahmen und der Ausbreitung zu beiden Seiten des Stickrahmens im Wege stehen. Dies hätte dann zur Folge, dass die dem Stickrahmen benachbarten Stoffbahnabschnitte durch die Stützpfeiler gegenüber dem im Stickrahmen eingespannten Stoffbahnabschnitt horizontal verschoben wären, wodurch sich in der Stoffbahn im Übergangsbereich zwischen diesen Abschnitten Auffaltungen und Verwerfungen ausbilden würden. Dies hätte vielfältige Störungen und Komplikationen im Arbeitsablauf zur Folge, deren Intensität mit zunehmender Breite der Stoffbahn überproportional anwachsen würde.Due to the transverse orientation of the bridge-shaped holding frame and its measured in the transverse direction of large clear width, the machine frame has a running in the longitudinal direction of free passage space. This makes it possible for the first time in multi-head embroidery machines endless webs can be moved through the machine completely unhindered in the longitudinal direction and processed. In contrast, in conventional multi-head embroidery machines, where the upper and lower support beams are attached to two end-mounted buttresses, endless webs would be processed, the pillars would feed and guide away the webs to or from the hoop and the spread on both sides of the hoop in the way. This would then mean that the fabric web sections adjacent to the embroidery frame would be displaced horizontally by the supporting pillars in relation to the fabric web section clamped in the embroidery hoop, whereby folds and warping would form in the fabric in the transition region between these sections. This would result in a variety of disturbances and complications in the workflow, the intensity of which would increase disproportionately with increasing width of the fabric.
Da die gegenseitig beabstandeten Halterahmen den Querzugang zum Stickrahmenträger und den ggf. in ihn eingesetzten Stickrahmen nicht behindern, können auch die üblichen Stickarbeiten an Stoffzuschnitten und Stoffeinzelteilen nach wie vor ohne Beeinträchtigung durchgeführt werden. Auf diese Weise können somit auf der erfindungsgemäßen Mehrkopfstickmaschine unter Verwendung aller Stickköpfe einzelne Stoffzuschnitte, kleinere Stoffeinzelteile oder endlose Stoffbahnen bestickt werden, wobei sich die Stickmuster über die gesamte Breite des Stickgutes erstrecken können, oder insbesondere bei Stoffbahnen auch nach der Art von Bordüren nur entlang der Stoffbahnränder verlaufen.Since the mutually spaced support frame does not hinder the cross-access to the embroidery frame carrier and possibly used in him hoop, the usual embroidery work on fabric blanks and fabric items can still be carried out without interference. In this way, individual fabric blanks, smaller fabric pieces or endless webs can thus be embroidered on the multi-head embroidery machine according to the invention using all the embroidery heads, wherein the embroidery patterns can extend over the entire width of the embroidery material, or especially in fabric even after the type of borders only along the Runway edges run.
Durch die
Durch die Weiterbildung der Halterahmen gemäß Anspruch 2 wird eine in sich ringförmig geschlossene und damit besonders formstabile Halterung für die Tragbalken geschaffen.Due to the development of the support frame according to
Bei herkömmlichen Mehrkopfstickmaschinen weist das Antriebssystem für die Stickköpfe und die Greiferaggregate eine gemeinsame Antriebsvorrichtung auf, wobei die notwendige Synchronisierung der Stickkopfantriebswelle mit der Greiferantriebswelle über einen Zahnriemen erfolgt, der in einer vertikalen Ebene verläuft. Ein solcher Zahnriemen würde jedoch die Erstreckungsebene einer dem Stickrahmen zuzuführenden oder in Arbeit befindlichen Stoffbahn kreuzen und somit deren freie Ausbreitung behindern. Zur Lösung dieses Problems wird daher im Anspruch 3 vorgeschlagen, die bisherige mechanische Synchronisierung durch eine an sich bekannte regelungstechnische bzw. elektronische Synchronisierung zu ersetzen.In conventional multi-head embroidery machines, the drive system for the embroidery heads and the gripper units on a common drive device, wherein the necessary synchronization of the embroidery head drive shaft with the gripper drive shaft via a toothed belt which extends in a vertical plane. However, such a timing belt would cross the plane of extension of the embroidery hoop to be supplied or in-process fabric and thus impede their free propagation. To solve this problem, it is therefore proposed in
