Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Transport eines flächigen Warenstückes, beispielsweise eines Abschnittes einer Warenbahn aus textilem Werkstoff, aus Papier, aus Pappe, aus Kunststoff, aus Blech oder aus einer Folie, wobei das Warenstück in vornehmlich horizontaler Ausrichtung von einem ersten Transportmittel an ein zweites Transportmittel übergebbar ist.The invention relates to a device for Transport of a flat piece of goods, for example a section of a web of textile, of paper, of cardboard, of Plastic, sheet metal or a film, whereby the goods in primarily horizontal Alignment from a first means of transport second means of transport is transferable.
Desweiteren betrifft die Erfindung ein Verfahren zum Transport von Warenstücken.Furthermore, the invention relates to a method for the transport of goods.
Im Stand der Technik ist eine Vorrichtung zum Transport von Warenstücken, insbesondere von aus einer textilen Bahn vereinzelten Textilstücken bekannt. Diese besteht aus einer ersten diskontinuierlich arbeitenden Transporteinrichtung, mittels derer eine textile Bahn von einem Warenspeicher abziehbar und das zu vereinzelnde freie Ende der Bahn gegebenenfalls gespannt gehalten ist, sowie einer zweiten kontinuierlich laufenden Transporteinrichtung, deren Transportebene parallel zur Transportebene der ersten Transporteinrichtung verläuft und die Mittel zum Halten des vereinzelten Textilstückes aufweist, wobei die Transportrichtung der ersten Transporteinrichtung parallel zur Bahnlängsrichtung und die Transportrichtung der zweiten Transporteinrichtung quer zur Bahnlängsrichtung gerichtet ist, vorzugsweise die erste Transpcrteinrichtung aus einem Transportschieber für die textile Bahn und einer Transportzange besteht, wobei die Zange zum Transportschieber hin und von diesem weg verstellbar ist, zwischen Transportschieber und Transportzange eine Trennvorrichtung angeordnet ist, mittels derer die Textilbahn zur Erzeugung eines vereinzelten Textilstückes durchtrennbar ist, das vereinzelte Textilstück nach oder bei gleichzeitig erfolgtem Trennschnitt und Freigabe vom ersten Transportmittel, insbesondere Transportschieber und der Transportzange, durch ein Übergabemittel aus der Ebene der ersten Transporteinrichtung in die Ebene der zweiten Transportvorrichtung verschiebbar ist und dieser zuführbar ist.In the prior art, a device for Transport of goods, especially from a textile web of isolated pieces of textile known. This consists of a first one discontinuous transport device, by means of which a textile web of one Removable storage and the items to be separated free end of the web possibly tensioned is held, and a second continuously running transport device whose Transport level parallel to the transport level of the first transport device runs and the funds for holding the isolated piece of textile, the direction of transport of the first Transport device parallel to Longitudinal direction and the transport direction of the second transport device transversely to the longitudinal direction of the web is directed, preferably the first Transport device from a transport slide for the textile web and a transport tongs exists, with the pliers towards the transport slide and adjustable from this, between Transport slider and transport tongs one Separating device is arranged, by means of which the Textile web to produce a single Textile piece is severable, the isolated Textile piece after or at the same time Separation cut and release from the first Means of transport, especially transport slides and the transport tongs by a transfer device from the level of the first transport device in the level of the second transport device is displaceable and this can be fed.
Im Stand der Technik ist es üblich, daß eine textile Bahn von einem Warenspeicher abgezogen wird und ein Teilstück von dieser Textilbahn abgetrennt wird. Dieses vereinzelte Textilstück wird dann zu einer Weiterverarbeitungsstation oder zu einer Weitertransportstation überführt. Sobald das Textilstück aus dem Bereich abtransportiert ist, in welchem die Textilbahn von dem Warenspeicher abgezogen wird, kann ein weiteres Textilstück von der textilen Bahn abgetrennt werden und wiederum abtransportiert werden.In the prior art, it is common for a textile web is pulled from a goods store and part of this textile web was cut off becomes. This isolated piece of textile then becomes a processing station or to one Transfer station transferred. As soon as that Piece of textile is removed from the area, in which the textile web from the store is pulled off, another piece of textile from the textile web are separated and again be transported away.
Solche Ausbildungen sind nachteilig, weil während der Zeitdauer, in der das vereinzelte Textilstück aus dem Bereich abtransportiert wird, in welchem die Vereinzelung der Textilstücke erfolgt, kein weiteres Textilstück vereinzelt werden kann, sondern dies kann erst dann erfolgen, wenn das schon vereinzelte Textilstück vollständig abtransportiert ist. Hierdurch ist es nicht möglich bei stetig angetriebenem Abtransport die vereinzelten Textilstücke quasi spaltfrei aneinanderliegend abzutransportieren und beispielsweise einer Säum- und Näheinrichtung zuzuführen, sondern es verbleibt immer zwischen den einzeinen Textilstücken ein großer Abstandspalt, was sich auf die Gesamtleistung der mit dieser Vorrichtung bestückten Nähanlage bezüglich des Stückzahlausbringens negativ auswirkt.Such training is disadvantageous because during the length of time in which the isolated piece of textile is transported out of the area in which the pieces of textile are separated, none another piece of textile can be separated, but this can only happen if that already isolated piece of textile completely is transported away. This makes it impossible with continuously driven removal the isolated pieces of textile virtually free of gaps to be transported next to each other and for example a hem and sewing device feed, but it always remains between the single pieces of textile a large gap, which affects the overall performance of this Device equipped sewing system regarding the Output of pieces has a negative impact.
Es sind auch schon Vorrichtungen mit übereinanderliegenden Quer- und Längstransportebenen bekannt. Dabei wird das Textilstück auf Nadelleisten fixiert, von der Textilbahn abgetrennt und von den Nadelleisten zu Nadelketten als Quertransportmittel verfahren sowie an diese übergeben. Eine solche Vorrichtung ist hinsichtlich der Ausbildung und Ausrichtung der Nadelleisten kompliziert und schwierig zu handhaben, wobei zudem als Nachteil empfunden wird, daß durch die Nadelleisten eine Beschädigung des textilen Werkstückes erfolgt, die in vielen Fällen nicht erlaubt ist.There are also devices with superimposed ones Cross and longitudinal transport planes known. The textile piece is placed on needle bars fixed, separated from the textile web and from the Needle bars for needle chains as a means of transport proceed and handed over to them. Such Device is in terms of training and Alignment of the needle bars complicated and difficult to handle, but also as a disadvantage is felt that through the needle bars Damage to the textile workpiece occurs is not allowed in many cases.
Grundsätzlich besteht bei solchen Vorrichtungen,
insbesondere auch Vorrichtungen, der im Oberbegriff
des Anspruches 1 genannten Art das Problem, daß es
äußerst schwierig ist, die vereinzelten Warenstücke

Aus der DE 43 28 461 A 1 ist ein Verfahren und eine Anordnung zum Fördern flächiger Werkstücke bekannt. Dabei ist ein Vorförderer und ein Folgeförderer vorgesehen. Mittels dieser Fördereinrichtungen werden Stoffteile zugeführt. Hierbei erfolgt die diskontinuierliche Förderung des Textilstückes mit der Vorfördereinrichtung in der Weise, daß bei Start des Vorförderers mit einem auf seine Förderbahn aufgelegten Textilstück, dessen Förderbahn soweit über die Förderbahn des Folgeförderers verlängert wird, daß das Werkstück vollständig über die Förderbahn des Folgeförderers verfahren werden kann. In dieser Position angekommen, wird das Werkstück bei stillgesetztem Fördermittels des Vorförderers durch Verkürzen der Förderbahn des Vorförderers auf den Förderband des Folgeförderers abgelegt. DE 43 28 461 A1 is a method and an arrangement for conveying flat Workpieces known. There is one Pre-conveyor and a follow-up conveyor intended. By means of this Conveyors become parts of fabric fed. This is where the discontinuous promotion of Textile piece with the pre-conveyor in such a way that when the Pre-conveyor with one on its conveyor track applied textile piece, its conveyor track so far on the conveyor of the Follow-up conveyor is extended that the Workpiece completely over the conveyor track of the subsequent conveyor can be moved. Once in this position, it will Workpiece with the conveyor stopped of the pre-conveyor by shortening the Conveyor of the pre-conveyor on the Conveyor belt of the subsequent conveyor stored.
Eine ähnliche Ausbildung ist aus der DE 11 32 861 B bekannt, bei der ein Förderband und eine Ablegevorrichtung vorgesehen ist. Die Ablegevorrichtung ist ein in und entgegen der Förderbewegung des Förderbandes verschiebbarer Wagen, der während des Ablegevorganges entgegen der Förderbewegung des Förderbandes verschoben wird, während zugleich das Ablegeband relativ zum Ablegetisch stillsteht. Zusätzlich ist dabei vorgesehen, daß die wirksame Länge des Ablegebandes zuzüglich eines dieses gegebenenfalls verlängernden Leitbleches auf die eingestellte Länge der Aus- und Einfahrbewegung seines Wagens und die Länge des abzulegenden Bahnabschnittes so abgestimmt wird, daß dieser bei Beginn der Einfahrbewegung mit seiner Vorderkante die Stapeloberseite an dessen Vorderseite ganz oder nahezu, vorzugsweise an einem auf dem Stapeltisch anstellbaren Anschlag berührt. A similar education is out of the DE 11 32 861 B known in which a Conveyor belt and a storage device is provided. The filing device is one in and against the funding movement of the Conveyor belt sliding carriage, the during the laying process against the Conveyor movement of the conveyor belt postponed while at the same time the storage tape stands still relative to the lay-up table. In addition, it is provided that the effective length of the storage tape plus one that may extend this Baffles to the set length of the Extending and retracting movement of his car and the length of the track section to be deposited is coordinated so that this at the beginning the retracting movement with its leading edge the top of the stack at the front completely or almost, preferably on one adjustable stop on the stacking table touched.
Ausgehend von dem eingangs bezeichneten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung gattungsgemäßer Art zu schaffen, die es in einfacher Weise ermöglicht, vereinzelte Warenstücke in exaktem Abstand voneinander gegebenenfalls auch spaltfrei oder nahezu spaltfrei nacheinander kontinuierlich abzutransportieren, so daß diese einer nachgeordneten Arbeitsstation, beispielsweise bei Textilstücken einer Näheinrichtung, zugeführt werden können und die Leistung der nachgeordneten Maschine oder Vorrichtung voll ausgenutzt werden kann.Based on the status of Technology is the object of the invention, to create a device of the generic type, which enables it to be isolated in a simple manner Goods at an exact distance from each other if necessary also gap-free or almost gap-free to be transported continuously in succession, so that this is a subordinate workstation, for example in textile pieces Sewing device, can be fed and the Performance of the downstream machine or Device can be fully used.
Die Lösung dieser Aufgabe ist im Anspruch 1
angegeben. The solution to this problem is in
Das zweite Transportmittel besteht dabei beispielsweise aus einem bandartigen Stetigförderer, der nicht als umlaufendes Fördermittel ausgebildet sein muß, sondern der auch ein reversierendes Fördermittel in Form eines nicht geschlossenen reversierend betriebenen Bandabschnittes sein kann. Durch ein Förderelement oder auch durch die quer zur Förderrichtung voneinander beabstandeten Förderelemente kann das Warenstück in einem Bereich der parallel zur Förderrichtung gerichtet ist, jeweils mit einem Förderelement ergriffen werden, welches das Warenstück gegen die entsprechende streifenartige Auflagefläche preßt und transportiert. Der Abstand zwischen den Förderelementen kann gegebenenfalls eingestellt werden, um unterschiedlich breite Warenstücke fördern zu können. Dadurch, daß die Förderelemente jeweils unter Bildung einer Pufferschlaufe umgelenkt und geführt sind, wird erreicht, daß die Förderelemente entgegen der eigentlichen Transportrichtung mit ihrem dem ankommenden Warenstück entgegengerichteten Umlenkende entgegen Förderrichtung verschoben werden können (parallel zur Förderebene, die durch die Auflagefläche gebildet ist). Hierdurch wird das entsprechend zugeführte Warenstück zeitlich früher übernommen, als wenn ein stationärer Stetigförderer eingesetzt würde. Nach der Übernahme des Warenstückes durch die Förderelemente können die Förderelemente unter Mitnahme des in Eingriff befindlichen Warenstückes aus der Übernahmestellung wieder in die Grundstellung zurückverfahren, so daß der Platz für die Anordnung eines weiteres Warenstückes geschafft ist, welches wiederum durch entgegen der Förderrichtung verstelltes Transportmittel in der Übernahmestellung übernommen wird.The second means of transport is there for example from a band-like Continuous conveyor, not as a rotating one Funding must be trained, but also a reversing funding in the form of a closed reversibly operated Band section can be. Through a conveyor element or also through the cross to the conveying direction spaced apart conveyor elements can Goods in an area parallel to Direction of delivery is directed, each with a Conveyor element are taken, which the Piece of goods against the corresponding strip-like Contact surface presses and transports. The distance between the conveyor elements, if necessary can be set to different widths To be able to convey goods. Because the Funding elements each with formation of a Buffer loop is deflected and guided achieved that the conveyor elements against the actual transport direction with your incoming goods opposing Deflector shifted against the conveying direction can be (parallel to the funding level, which by the contact surface is formed). This will correspondingly supplied goods earlier taken over as if a stationary continuous conveyor would be used. After taking over the Goods through the conveyor elements can Conveyor elements with the entrainment located goods from the takeover position move back to the basic position so that the place for arranging another Piece of goods is done, which in turn by adjusted against the conveying direction Means of transport taken over in the takeover position becomes.
Bei der im Anspruch 1 angegebenen alternativen
Lösung wird das komplette Förderelement mit
Umlenkrad und Antriebsrad entgegen der
Förderrichtung während des Umlaufs des
Förderelementes verstellt, um das vereinzelte
Warenstück zu übernehmen. Anschließend wird das
Förderelement während des Weiterförderns des
Warenstückes in die Grundstellung zurückverstellt.
Die sich hieraus ergebenden Vorteile entsprechen
den oben bezüglich der ersten Alternative
angegebenen.In the alternative specified in
Als besonders bevorzugt ist vorgesehen, dass parallel zu den Förderelementen des ersten Förderers neben diesen jeweils ein weiteres Förderelement eines zweiten Förderers angeordnet ist, welche Förderelemente des zweiten Förderers mit gleicher Transportrichtung und Geschwindigkeit wie die Förderelemente des ersten Förderers betrieben sind und daß der Umlenkbereich der Förderelemente des ersten Förderers dadurch in Transportrichtung aus der Übernahmestellung in die Grundstellung zurückverstellbar ist, daß das Warenstück von den Förderelementen des zweiten Förderers in Förderrichtung transportiert ist und sich der Umlenkbereich des ersten Förderers auf dem Warenstück abstützt und von dem Warenstück in Transportgeschwindigkeit zurück in die Grundstellung mitgenommen ist.It is particularly preferred that parallel to the conveyor elements of the first In addition to each of these Conveying element of a second conveyor arranged is which conveyor elements of the second conveyor with the same transport direction and speed like the conveyor elements of the first conveyor are operated and that the deflection area of the Conveying elements of the first conveyor in Direction of transport from the takeover position to Reset position is that the Goods from the conveyor elements of the second Conveyor is transported in the direction of conveyance and the deflection area of the first conveyor on the Supported piece of goods and from the piece of goods in Transport speed back into the Home position is taken.
Die parallel zu den Förderelementen des ersten Förderers, insbesondere Stetigförderers jeweils vorgesehenen weiteren Förderelemente eines zweiten Förderers, insbesondere Stetigförderers sind vorzugsweise eng benachbart zu den Förderelementen des ersten Förderers, insbesondere Stetigförderers angeordnet.The parallel to the conveyor elements of the first Conveyor, in particular continuous conveyor each provided further funding elements of a second Are conveyor, in particular continuous conveyor preferably closely adjacent to the conveyor elements of the first conveyor, in particular a continuous conveyor arranged.
Durch diese Ausbildung ist sichergestellt, daß das zunächst von dem ersten Förderelement übernommene Warenstück von den Förderelementen des zweiten Förderers übernommen wird, wobei es gleichzeitig noch mit den Förderelementen des ersten Förderers in Kontakt ist. Die Förderelemente des ersten Förderers können dabei aus der Übernahmestellung in die Grundstellung in Transportrichtung verstellt werden, wobei hierdurch quasi der erste Stetigförderer keine Relativbewegung zu dem Warenstück ausführt, sondern mit dem Warenstück in die Grundstellung transportiert wird. Anschließend kann zur Übernahme eines weiteren Warenstücks der Stetigförderer entgegen der Förderrichtung verstellt werden, und zwar entweder nach Erreichen der Grundstellung oder auch schon vor Erreichen der Grundstellung, so daß die Förderelemente des ersten Stetigförderers auf dem neu zugeführten Warenstück ablaufen, dieses transportieren bis zumindest zur Eingriffslage des zweiten Stetigförderers und anschließend wieder mit dem Warenstück in die Grundstellung oder eine Zwischenstellung zurückgeführt werden können, aus welcher wir erneut entgegen Transportrichtung die Übernahme des nächsten Warenstückes verstellt werden können.This training ensures that initially taken over by the first conveying element Goods from the conveyor elements of the second Sponsor is taken over, at the same time still with the conveyor elements of the first conveyor is in contact. The funding elements of the first Sponsors can from the Takeover position in the basic position in Transport direction can be adjusted, thereby quasi the first continuous conveyor none Executes relative movement to the piece of goods, but with the item in the basic position is transported. Then you can take over another piece of the continuous conveyor be adjusted against the direction of conveyance, and either after reaching the basic position or even before reaching the basic position, so that the conveyor elements of the first continuous conveyor expire the newly supplied item, this transport up to at least the engagement position of the second continuous conveyor and then again with the item in the basic position or a Intermediate position can be traced out which we again against the direction of transport Takeover of the next item blocked can be.
Bevorzugt ist zudem vorgesehen, daß beide Förderer endlos umlaufend ausgebildet sind.It is also preferably provided that both conveyors are endlessly trained.
Eine besonders zweckmäßige Weiterbildung wird darin gesehen, gesehen, daß beide Förderer Zahnriemen als Förderelemente aufweisen, die mit Zahnrädern als Umlenkräder und Antriebsräder in Eingriff sind.A particularly useful training is in it seen, seen that both conveyors as timing belts Have conveying elements that with gears as Deflection wheels and drive wheels are engaged.
Zudem ist bevorzugt vorgesehen, daß die jeweils, vorzugsweise eng, benachbarten Förderelemente des ersten und zweiten Förderers durch jeweils einen gemeinsamen Antrieb angetrieben sind, wobei die Antriebe der beiden Förderelementpaare synchron und gleichlaufend betrieben sind.In addition, it is preferably provided that the respective preferably narrow, adjacent conveyor elements of the first and second conveyor by one each common Drive are driven, the drives of the two conveyor element pairs synchronously and are operated in sync.
Zudem kann vorgesehen sein, daß der Stellantrieb zur Bewegung des Förderelementes oder des entgegen Förderrichtung gerichteten Umlenkbereiches mit einer Einrichtung gekoppelt oder von einer Einrichtung gesteuert ist, mittels derer die Vorlage eines Warenstückes sowie die Sollposition des Warenstückes unter dem ablaufenden Untertrum des Förderelementes des ersten Förderers erfaßbar ist. It can also be provided that the actuator to move the conveying element or counter Conveying direction directed with coupled to or from a facility Is controlled by means of which the Submission of a piece of goods and the target position of the goods under the running lower run of the conveyor element of the first conveyor can be detected is.
Auch kann vorgesehen sein, daß der Stellantrieb zur Bewegung des Förderelementes oder des entgegen Fördereinrichtung gerichteten Umlenkbereichs mit einer Einrichtung gekoppelt beziehungsweise von einer Einrichtung gesteuert ist, mittels derer die Position eines Warenstückes unter dem ablaufenden Untertrum des Förderelementes des zweiten Stetigförderers erfaßbar ist.It can also be provided that the actuator for Movement of the conveyor element or the opposite Conveyor directed deflection area coupled to a facility or by is controlled by means of which the Position of a piece of goods under the expiring Lower strand of the conveyor element of the second Continuous conveyor is detectable.
Als Positionserfassungseinrichtungen können beispielsweise Lichtschranken, andere berührungsfreie Erfassungsorgane oder auch Berührungstaster oder dergleichen vorgesehen sein. Mittels dieser Erfassungselemente kann beispielsweise die in Förderrichtung hinten liegende Randkante des Warenstückes, welches abtransportiert wird, erfaßt werden oder die in Förderrichtung vornliegende Randkante des nächsten ankommenden Warenstückes oder auch bei der Übergabe und Übernahme durch den ersten Stetigförderer, wie in Förderrichtung hintere Randkante des mit dem ersten Stetigförderer in Eingriff befindlichen Warenstückes erfaßt werden, um dieses beispielsweise exakt der Randkante vertikal unter der Drehachse der den Umlenkbereich bildenden Rolle oder dergleichen zu positionieren. Das nächste Warenstück kann dann bis an diese Randkante angenähert werden, so daß es, sofern erwünscht, spaltfrei oder nahezu spaltfrei an das schon in Eingriff befindliche Warenstück angeschlossen werden kann. Can be used as position detection devices for example light barriers, others non-contact detection organs or Touch buttons or the like may be provided. By means of these detection elements for example the rear in the conveying direction lying edge of the item, which is transported, recorded or the in Direction of conveyance leading edge of the next arriving piece of goods or also at the handover and takeover by the first continuous conveyor, such as in the conveying direction of the rear edge of the first continuous conveyor engaged Piece of goods can be recorded to this for example exactly the edge vertically below the axis of rotation of the roller forming the deflection area or the like to position. The next Goods can then go up to this edge be approximated so that, if desired, gap-free or almost gap-free at that already in Interested goods connected can be.

Dadurch, daß die beiden Transporteinrichtungen quasi übereinander angeordnet sind, ist es möglich, das Warenstück, insbesondere die textile Bahn von dem Warenspeicher soweit abzuziehen, wie dem Maß des zu vereinzelnden Warenstückes entspricht. Anschließend kann das Warenstück zum Zwecke der Vereinzelung von der Bahn abgetrennt werden, wobei das Abtrennen mittels eines Kreismessers oder auch mittels eines Schneidbalkens erfolgen kann. Vor dem Trennvorgang wird das zu vereinzelnde Warenstück an den Querrandkanten (in Richtung der Warenbahn gesehen) mittels der Klemmeinrichtung erfaßt und lagerichtig gehalten. Die Klemmeinrichtung wird dann samt dem vereinzelten Warenstück in die zweite Transportebene überführt, in der die zweite kontinuierlich betriebene Transporteinrichtung angeordnet ist. Das Warenstück wird dabei an seinen Randkanten derart gehalten, daß die Ränder über die beiden an den beiden Randkanten angeordneten Klemmeinrichtungen vorragen. Mittels der Klemmeinrichtung wird das vereinzelte Warenstück dann in der Ebene der zweiten Transportvorrichtung zu dieser hin bewegt, wobei gleichzeitig die zweite Transportvorrichtung, die vorzugsweise aus Transportriemen besteht, die kontinuierlich umlaufen und sich auf einem Auflagetisch oder auf Auflagekufen abstützen, entgegen der Vorwärtsbewegung der Klemmeinrichtung auf diese zu bewegt wird. Die über die Klemmeinrichtung beidseitig vorragenden Randstücke werden dann von der zweiten Transportvorrichtung ergriffen, die das Warenstück abtransportiert. Dabei bewegt sich nach der Übergabe des in Transportrichtung vorderen Endes des Randteiles an die zweite Transportvorrichtung die Transportvorrichtung gemeinsam mit dem abgeförderten Textilstück unter gleichzeitigem Abtransport des Textilstückes in die Ausgangslage zurück, in der die Transportvorrichtung Abstand von der Klemmeinrichtung aufweist, wobei zudem die Klemmeinrichtung ebenfalls in die Ausgangslage zurückbewegt wird, also von der zweiten Transportvorrichtung entfernt und in die Ebene der ersten Transporteinrichtung verschoben wird.The fact that the two transport devices are arranged one above the other, it is possible the item, in particular the textile web from subtract from the store as much as the measure corresponds to the item to be separated. The piece of goods can then be used for the purpose of Separation can be separated from the web, whereby cutting off with a circular knife or can be done by means of a cutting bar. Before the Separation process is the piece of goods to be separated the transverse edge (in the direction of the web seen) detected by means of the clamping device and held in the correct position. The clamping device will then together with the individual item in the second Transport level transferred to the second continuously operated transport facility is arranged. The piece of goods will be on Border edges held so that the edges over the both arranged on the two edges Protruding clamping devices. By means of the Clamping device becomes the isolated item then in the plane of the second transport device moved towards this, at the same time the second Transport device, preferably made of Conveyor belts are made continuously circulate and on a support table or on Support the support runners against the Forward movement of the clamping device towards this is moved. The via the clamping device edge pieces projecting on both sides are then from seized the second transport device that the Item removed. This moves after the handover of the front in the direction of transport End of the edge part to the second Transport device the transport device together with the removed piece of textile under simultaneous removal of the textile piece into the Starting position in which the Transport device distance from the Has clamping device, which also Clamping device also in the starting position is moved back, i.e. from the second Transport device removed and in the plane of the first transport device is moved.
Durch diese gegenläufige Bewegung der zweiten Transportvorrichtung und der Klemmeinrichtung bei der Übergabe des Warenstückes wird erreicht, daß das Warenstück mit seiner in Förderrichtung der zweiten Fördereinrichtung vorn liegenden Randkante der hinteren Randkante des schon abgeförderten Warenstückes, welches noch von der zweiten Transportvorrichtung abtransportiert wird, unmittelbar angenähert wird, so daß das folgende Warenstück quasi spaltfrei oder unter ganz geringer Spaltbildung von der zweiten Transportvorrichtung mitgenommen wird und weiterverarbeitenden Stationen zugeführt werden kann. Dabei ist durch die erfindungsgemäße Ausbildung eine Beschädigung des Warenstückes durch Nadeln oder dergleichen vermieden.Through this opposite movement of the second Transport device and the clamping device the delivery of the item is achieved that the piece of goods with its in the conveying direction second conveyor front edge the rear edge of the already removed Piece of goods, which is still from the second Transport device is removed, is immediately approximated so that the following Piece of goods virtually gap-free or under very little Gap formation from the second transport device is taken along and further processing stations can be supplied. It is through the Training according to the invention damage the Goods by needles or the like avoided.
In Konsequenz können die der zweiten Transportvorrichtung nachgeordneten Stationen, wie Säumeinrichtung und/oder Näheinrichtung kontinuierlich mit Höchstleistung betrieben werden und deren Leistung kann vollständig ausgenutzt werden.As a consequence, those of the second transport device subordinate stations, such as hemming equipment and / or sewing device continuously with Maximum performance are operated and their performance can be fully exploited.
Eine bevorzugte Weiterbildung wird darin gesehen, daß das zweite Transportmittel aus Förderelementen in Form von Transportriemen besteht, die in Transportrichtung außen neben der von der Klemmeinrichtung bei deren Bewegung aufgespannten Fluchtebene der Klemmeinrichtung angeordnet sind und die den Rand des Warenstückes gegen Auflagebereiche (10) als Bestandteil jeder der beiden Transportvorrichtungen andrücken.A preferred further development is seen in that the second means of transport from conveyor elements in the form of transport belts, which in Direction of transport outside next to that of the Clamping device clamped when moving Alignment level of the clamping device are arranged and against the edge of the piece of goods Support areas (10) as part of each press on both transport devices.
Bevorzugt kann vorgesehen sein, daß die Klemmeinrichtung aus Klemmbalkenpaaren besteht.It can preferably be provided that the Clamping device consists of pairs of clamping bars.
Auch ist bevorzugt, daß die Klemmeinrichtung und die Transportvorrichtung einander derart annäherbar sind, daß das von der Klemmeinrichtung gehaltene Warenstück mit seinen Rändern an die Transportvorrichtung übergebbar ist, wobei das übergebene Warenstück spaltfrei oder nahezu spaltfrei an ein vorher übergebenes, von der Transportvorrichtung abtransportiertes Warenstück anschließt.It is also preferred that the clamping device and the transport device so approachable to each other are that held by the clamping device Goods with its edges on the Transport device is transferable, which passed goods gap-free or almost to a previously handed over, from the Transport device removed piece of goods followed.
Für den Übergabevorgang ist ferner vorteilhaft, wenn der Anlagebereich durch eine ebene Auflageplatte oder einen Auflagetisch gebildet ist. Unter Umständen kann auch vorgesehen sein, daß der Auflagebereich durch jeweils einen weiteren Stetigförderer gebildet ist. For the transfer process it is also advantageous if the investment area through a level Platen or a support table is formed. Under certain circumstances it can also be provided that the support area by one more Continuous conveyor is formed.
Hierbei kann der Auflagebereich jeweils durch einen endlos umlaufenden Stetigförderer gebildet sein, dessen eines Trum als Gegenfläche für den Stetigförderer mit dem Förderelement dient und gleichgerichtet und mit gleicher Geschwindigkeit in Transportrichtung abläuft.Here, the support area can each by endless continuous conveyor be formed, of which one strand as a counter surface for the Continuous conveyor with the conveyor element serves and rectified and at the same speed in Direction of transport expires.

In der Zeichnung sind die wesentlichen Elemente
einer Vorrichtung zum Transport von aus einer
textilen Bahn 1 vereinzelten Warenstücken 1',
insbesondere Textilstücken,
gezeigt. Die Vorrichtung besteht im wesentlichen
aus einer ersten diskontinuierlich arbeitenden
Transporteinrichtung, mittels derer die Warenbahn 1
von einem nicht gezeigten Warenspeicher abziehbar
ist und das zu vereinzelnde freie Ende der Bahn -
gegebenenfalls- gespannt- gehalten ist. Ferner
besteht die Vorrichtung aus einer zweiten
kontinuierlich laufenden Transporteinrichtung,
deren Transportebene parallel zur Transportebene
der ersten Transporteinrichtung verläuft und die
Mittel zum Halten des vereinzelten Warenstückes 1'
aufweist. Die Transportrichtung der ersten
Transporteinrichtung ist bei 5 angegeben. Die
Transportrichtung der zweiten Transportvorrichtung
ist gemäß Figur 1 orthogonal zur Zeichnungsebene
und in Figur 2 mit dem Pfeil 6 angegeben. Die
Transportebenen der beiden Transporteinrichtungen
verlaufen parallel zueinander und mit Abstand
übereinander. Die Transportrichtung 5 der ersten
Transporteinrichtung verläuft parallel zur
Bahnlängserstreckung der Bahn 1, während die Transportrichtung
der zweiten Transporteinrichtung quer
zur Bahnlängsrichtung gerichtet ist.The essential elements are in the drawing
a device for transporting from a
Die erste Transporteinrichtung besteht aus einem
Transportschieber 7 für die Warenbahn 1 und einer
Transportzange 4, wobei die Zange 4 entsprechend
dem Bewegungspfeil 8 zum Transportschieber 7 hin
und von diesem weg
verstellbar ist. Zwischen Transportschieber 7 und
Transportzange 4 ist in der Nähe des
Transportschiebers 7 ein Trennmittel 9 vorgesehen,
mittels derer die Warenbahn 1 zur Erzeugung eines
vereinzelten Warenstückes 1' durchtrennbar ist. Das
Trennmittel 9 ist im Ausführungsbeispiel als Schere
dargestellt. Es kann sich dabei um eine manuell
betätigbare Schere oder um ein motorisch betätigtes
Scheibenmesser oder auch um einen pneumatisch oder
motorisch betriebenen Trennbalken oder dergleichen
handeln. Das Warenstück 1' wird nach der
Durchführung des Trennschnittes oder gleichzeitig
bei Durchführung des Trennschnittes von dem
Transportschieber 7 und der Transportzange 4
freigegeben und durch ein Übergabemittel aus der
Ebene der ersten Transporteinrichtung in die Ebene
der zweiten Transporteinrichtung verstellt.The first transport device consists of a
Das Übergabemittel besteht aus einer
Klemmeinrichtung 2. Die Klemmeinrichtung 2 besteht
aus zwei Paaren von Klemmbalken, deren einer
oberhalb der Warenbahn 1 und deren anderer
unterhalb der Warenbahn 1 angeordnet ist, wobei das
vereinzelte Warenstück durch Schließen der
Klemmbalken der Klemmeinrichtung 2 fixiert wird.
Anschließend werden die Klemmbalken der
Klemmeinrichtung mit dem Warenstück 1' aus der in

Transportriemen der zweiten Transportvorrichtung
angeordnet ist, wie insbesondere aus Figur 1
ersichtlich ist, können die beiden Aggregate 2
beziehungsweise 3 einander überdeckend angenähert
werden, ohne das sie sich bei dieser Bewegung
gegenseitig stören oder berühren. Durch diese
Anordnung ist es möglich, das von der
Klemmeinrichtung 2 gehaltene Warenstück 1' so weit
der zweiten Transporteinrichtung beziehungsweise
deren Transportriemen anzunähern, daß die in
Vorschubrichtung vordere Randkante des Warenstückes
1' praktisch auf Stoß zu dem schon von der zweiten
Transporteinrichtung abgeförderten weiteren
Warenstück angenähert werden kann.The transfer means consists of a

Transportvorrichtung wieder von der
Klemmeinrichtung 2 in Förderrichtung weg verstellt
werden und ebenso die Klemmeinrichtung 2 von der
zweiten Transporteinrichtung weg zurück verstellt
werden, wobei die Klemmeinrichtung 2 gleichzeitig
oder nachfolgend in die Ebene der ersten
Transporteinrichtung überführt wird, so daß sie zur
Aufnahme der weiteren Warenbahn 1 und zum Zwecke
der Vereinzelung und Übergabe eines weiteres
Warenstückes geeignet ist. Die
Bewegungsmöglichkeiten der Aggregate 2 und 3
beziehungsweise von deren Einzelteilen sind durch
