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 US-A-3 336 886 ).In the industrial embroidery machines, there are essentially two types of machines, namely shuttle embroidery machines with horizontally movable needles for processing large-area, elongated pieces of cloth and endless panels, and multi-head embroidery machines with vertically movable needles, these machines being also referred to as hook and loop machines. They are used to edit fabric cuts or to simultaneously embroider several small fabric items (See U.S.-A-3,336,886 ).

Aus der DE 196 40 335 A1 ist der prinzipielle Aufbau einer Mehrkopfstickmaschine entnehmbar. Ein Maschinengestell weist einen langgestreckten, horizontal verlaufenden oberen Tragbalken für die Anordnung einer Mehrzahl von Stickköpfen und einen mit Abstand parallel zu diesem verlaufenden unteren Tragbalken für die Anordnung der zugeordneten Greiferaggregate auf. Die beiden Tragbalken sind an zwei endseitig angeordneten, vertikal verlaufenden Stützpfeilern befestigt. Auf dem unteren Tragbalken ist ferner eine Auflageplatte befestigt, die zur Aufnahme eines Stickrahmens dient. Der Stickrahmen ist durch einen Antriebsmechanismus parallel zur Auflageplattenebene in zwei Achsen frei bewegbar. Er dient vorwiegend zur Einspannung zu bestickender rechteckiger Stoffzuschnitte oder zur Aufnahme von Einspannvorrichtungen für eine Mehrzahl von Stoffeinzelteilen.From the DE 196 40 335 A1 is the basic structure of a multi-head embroidery machine removable. A machine frame has an elongated, horizontally extending upper support beam for the arrangement of a plurality of embroidery heads and a spaced parallel thereto extending lower support beam for the arrangement of the associated gripper units. The two support beams are attached to two ends arranged vertically extending pillars. On the lower support beam, a support plate is further attached, which serves to receive an embroidery frame. The embroidery hoop is freely movable in two axes by a drive mechanism parallel to the platen plane. It is mainly used for clamping to be embroidered rectangular fabric blanks or for receiving jigs for a plurality of fabric items.

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 DE 196 40 335 A1 Maßnahmen zur Erhöhung der Biegesteifigkeit der beiden Tragbalken vorgeschlagen. Da die übrigen Teile des Maschinengestells davon unbeeinflusst bleiben, soll dadurch der Gesamtaufbau nicht verkompliziert werden. Ein anderes Beispiel zeigt der Patent Abstracts of Japan 2000342876 . Dort ist bei einem üblich ausgebildeten Maschinengestell einer Mehrkopfstickmaschine eine zusätzliche mittige Befestigung des oberen Tragbalkens vorgesehen, wodurch Vibrationen vermindert werden sollen.There have been numerous attempts to reduce the tendency of embroidery machines to vibrate. So z. B. in the above DE 196 40 335 A1 Measures proposed to increase the bending stiffness of the two support beams. Since the remaining parts of the machine frame remain unaffected by this, the overall structure should not be complicated. Another example shows the Patent Abstracts of Japan 2000342876 , There is provided in a conventional machine frame of a multi-head embroidery machine, an additional central attachment of the upper support beam, which vibrations should be reduced.

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 EP 1 185 729 B1 offenbart, so auszubilden, dass eine oder mehrere Stoffbahnen in ihrer Längsrichtung quer zur Reihe der Stickköpfe durch die Stickmaschine hindurchgeführt wird bzw. werden, wobei die Stoffbahnen von einer vor der Stickmaschine angeordneten Halte- und Abwickelvorrichtung für die Rohware abgezogen und nach dem Besticken auf einer hinter der Stickmaschine angeordneten Halte- und Aufwickelvorrichtung für die Fertigware aufgewickelt wird. Diese Art der Stoffzuführung ist aber nur für Stickarbeiten geeignet, bei denen sich die Mustermotive wie bei Stepparbeiten über der Stoffbahnbreite wiederholen. Dagegen wäre es unzweckmäßig, solche Mustermotive zu sticken, die wie bei Bordüren entlang der Stoffbahnränder verlaufen und sich in Längsrichtung der Stoffbahn wiederholen, weil in diesem Fall nur ein Teil der Stickköpfe genutzt werden könnte.In addition to increasing the performance of the multi-head embroidery machines, it would be desirable if their application could be extended to the effect that even longer fabric blanks or even endless panels can be embroidered. Also in this regard, there have been corresponding attempts. Thus, it has already been proposed, multi-head embroidery machines, similar as in the EP 1 185 729 B1 discloses to form so that one or more panels are passed in their longitudinal direction transversely to the row of embroidery heads by the embroidery machine or, wherein the panels of a pre-embroidery machine arranged holding and unwinding device for the raw material withdrawn and after embroidering on a behind the embroidery machine arranged holding and winding device is wound up for the finished product. However, this type of fabric feed is only suitable for embroidery work in which repeat the pattern motifs as in stitching over the fabric width. By contrast, it would be impractical to embroider such pattern motifs, which run along the edges of the fabric as in borders and repeat themselves in the longitudinal direction of the fabric, because in this case only a part of the embroidery heads could be used.

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 DE 42 39 746 C2 und die DE 42 41 200 A1 sind zwar bei der Maschinengattung der Schiffchenstickmaschinen Lösungen zur Verringerung der Bauhöhe der Maschinengestelle und zur Vereinfachung der Fundamente bekannt, indem das Maschinengestell einen U-förmig offenen Querschnitt aufweist und aus in Längsrichtung aneinander reihbaren Moduleinheiten aufgebaut ist. Da hierbei die Tragbalken für die Nadelstangen und Fadengeber einerseits und die Tragbalken für die Schiffchen andererseits mit horizontalem Abstand einander gegenüber liegen und deshalb für die Abstützung dieser Tragbalken einfache, in vertikaler Ebene verlaufende Tragkonstruktionen aus Seitenständern und Längsträgern gebildet werden können, zwischen denen ein in vertikaler Ebene verlaufender durchgehender Kanal für die Aufnahme des sich ebenfalls in vertikaler Ebene erstreckenden Stickgutes ausgebildet ist, können diese Lösungsvorschläge keine Anregung für Schaffung eines Maschinengestells für Mehrkopfstickmaschinen geben, bei denen der Tragbalken für die Stickköpfe und der Tragbalken für die Greiferaggregate und die horizontale Auflageplatte für den Stickrahmenträger mit vertikalem Abstand übereinander angeordnet sind.By the DE 42 39 746 C2 and the DE 42 41 200 A1 Although in the machine class of shuttle embroidery machines solutions for reducing the overall height of the machine frames and for simplifying the foundations are known in that the machine frame has a U-shaped open cross-section and is constructed of modular units which can be aligned in the longitudinal direction. Since in this case the support bars for the needle bars and thread taketers on the one hand and the support beams for the boats on the other hand with horizontal distance from each other and therefore simple, running in a vertical plane supporting structures can be formed of side uprights and side rails, between which a vertical in the support of these support beams Level extending through channel for receiving the also extending in the vertical plane embroidery material is formed, these proposals for solutions can provide no incentive for creating a machine frame for multi-head embroidery machines, in which the support beam for the embroidery heads and the support beams for the gripper units and the horizontal support plate for the embroidery frame carrier are arranged one above the other with a vertical spacing.

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 claim 2, a self-contained annular and thus particularly dimensionally stable support for the support beams is created.

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 claim 3 to replace the previous mechanical synchronization by a known per se control engineering or electronic synchronization.
