Abstract

The invention relates to a transfer station (1) by means of which bristle filaments, which can be fed to the transfer station in bristle clusters (3), in which the bristle filaments are assembled in bundle form by means of at least one band (4), are transferred to a magazine (2), in which the bristle filaments are stored. The transfer station according to the invention is characterized in that the transfer station (1) has at least two pairs (8, 9) of gripping fingers (10, 11; 12, 13) spaced apart from one another in the longitudinal direction of the bundles, in that the gripping fingers (10, 11; 12, 13) of the gripping-finger pairs (8, 9) can be moved relative to one another, in order to grip a bristle cluster (3), such that the distance between said gripping fingers (10, 11; 12, 13) is reduced, and in that the gripping-finger pairs (8, 9) here grip the bristle cluster (3) such that at least one band (4) of the bristle cluster (3) is arranged between adjacent gripping-finger pairs (8, 9). The transfer station according to the invention makes it possible for the bristle filaments fed in bundle form to be transferred in an automated manner to the magazine, which is arranged upstream of a tufting tool of a brush-production machine (cf. figure 1).

Description

Übergabestation zur Übergabe von Borstenfilamenten  Transfer station for the transfer of bristle filaments
Die vorliegende Erfindung betrifft eine Übergabestation zur Übergabe von Borstenf ilamenten, die der Übergabestation in Borstenbündeln zuführbar sind, welche Borstenbündel die Bors- tenfilamente mittels wenigstens einem Band bündelweise zusammenfassen, an ein Magazin, in welchem Magazin die Borstenfila- mente bevorratet sind. The present invention relates to a transfer station for transferring bristle filaments which can be supplied to the transfer station in bristle bundles, which bristle bundles bundle the bristle filaments in bundles by means of at least one strip, to a magazine in which magazine the bristle filaments are stored.
In Bürstenherstellungsmaschinen werden Borstenf ilamente in ei- nen Bürstenkörper eingesetzt. Die in den Bürstenkörper eingesetzten Borstenfilamente bilden anschließend das Borstenfeld einer Bürste. In brush making machines, bristle filaments are inserted into a brush body. The bristle filaments used in the brush body then form the bristle field of a brush.
Man hat bereits chemisch angespitzte Borstenf ilamente geschaf- fen, die auch als „tapered filaments" bezeichnet werden. Diese angespitzten und in einer hauchdünnen Borstenspitze auslaufenden Borstenf ilamente werden weltweit zunehmend verwendet, um damit besonders weiche Zahnbürsten zu schaffen. Da diese Bors- tenfilamente besonders dünn sind, werden solche angespitzten Borstenfilamente bislang noch händisch in das Magazin einer Bürstenherstellungsmaschine eingelegt. Ein solches, auch als Materialkasten bezeichnetes Magazin weist zumindest eine, beidseits durch eine Seitenleiste begrenzte Förderstrecke auf, die einem StopfWerkzeug der Bürstenherstellungsmaschine vorgeschal - tet ist. These chemically sharpened bristle filaments, also referred to as "tapered filaments", have become increasingly popular all over the world for producing particularly soft toothbrushes, since these boron filaments are particularly effective Such a sharpened bristle filaments are still manually inserted into the magazine of a brush-making machine, such a magazine, also referred to as a material box, has at least one conveying path delimited on both sides by a sidebar, which is inserted upstream of a stuffing tool of the brush-making machine.
Die chemisch angespitzten Borstenelemente werden regelmäßig meist in, im Querschnitt rund zusammengefassten Borstenbündeln angeboten.

BESTÄTIGUNGSKOPIE dels durch zumindest ein Band und vorzugsweise durch zumindest ein Gummiband zusammengehalten. Beim händischen Einlegen der noch bündelweise zusammengehaltenen Borstenfilamente wird das Borstenbündel auf die Bodenplatte des Magazins gestellt und anschließend zwischen den Seitenleisten einer im Magazin vorgesehenen Förderstrecke bis zu beidseits an den Seitenleisten verfahrbaren Drückern vorgeschoben. Danach werden die die Borstenbündel noch zusammenhaltenden Gummibänder entfernt, um die Drücker durch Drück auf einen Taster hinter die nun bündellosen Borstenfilamente zu ziehen, damit die Drücker das neue Borstenmaterial gegen die in der Förderstrecke bereits befindlichen Borstenfilamente pressen kann. Da die angespitzten Borstenfilamente immer sehr gut umfasst werden müssen, kommt es gelegentlich dazu, dass der seitlich über die Seitenleisten vorstehende Drücker auch auf die Finger drückt. Da der Druck auf den Drücker nicht sehr groß ist, kommt es nur zu leichten Druckstellen. Da die Bürstenherstellungsmaschine während der Einlegephasen der Borstenbündel nicht angehalten werden soll, bewegt sich das Magazin, wenn von der einen Borstenfarbe zu einer anderen Borstenfarbe umgeschaltet werden muss . Hierdurch kann es, auch durch Unachtsamkeit des Bedieners, zu schwerwiegenden Quetschungen kommen. Solche Quetschungen und die damit verbundenen Verletzungen des Bedieners müssen jedoch unbedingt vermieden werden. CONFIRMATION COPY dels held together by at least one band and preferably by at least one rubber band. When manually inserting the bunched together held bristle filaments, the bristle bundle is placed on the bottom plate of the magazine and then advanced between the side rails of a magazine provided in the conveyor section up to both sides on the side rails movable pushers. Thereafter, the rubber bands still holding together the bristle bundles are removed in order to pull the pushers by pressing a button behind the now bundleless bristle filaments, so that the pushers can press the new bristle material against the bristle filaments already present in the conveyor line. Since the sharpened bristle filaments must always be very well embraced, it sometimes happens that the pusher protruding laterally over the side strips also presses on the fingers. Since the pressure on the pusher is not very great, it only causes slight bruises. Since the brush-making machine should not be stopped during the insertion phases of the bristle bundles, the magazine moves when it is necessary to switch from one bristle color to another bristle color. This can lead to serious bruising, even if the operator neglects it. However, such bruising and the associated injury to the operator must be avoided at all costs.
Es besteht daher insbesondere die Aufgabe, eine Übergabestation der eingangs erwähnten Art zu schaffen, welche die automatisierte Übergabe der bündelweise angelieferten Borstenfilamente zu dem, beispielsweise dem Stopf erkzeug einer Bürstenherstellungsmaschine vorgeschalteten Magazin erlaubt. There is therefore in particular the task of creating a transfer station of the type mentioned above, which allows the automated transfer of bundled delivered bristle filaments to, for example, the stuffing tool a brush making machine upstream magazine.
Die erfindungsgemäße Lösung besteht bei der Übergabestation der eingangs erwähnten Art insbesondere darin, dass die Übergabe- Station zumindest zwei, in Bündellängsrichtung voneinander be- abstandete Paare von Greiffingern hat, dass die Greiffinger der Greiffinger-Paare zum Ergreifen eines Borstenbündels quer zur Bündellängsrichtung derart relativ zueinander bewegbar sind, dass der Abstand dieser Greiffinger verringert wird, und dass die Greiffinger-Paare dabei das Borstenbündel derart ergreifen, dass zwischen benachbarten : Greiffinger-Paaren wenigstens ein Band des Borstenbündels angeordnet ist. The solution according to the invention in the transfer station of the type mentioned in the introduction is, in particular, that the transfer Station has at least two, in the bundle longitudinally spaced apart pairs of gripper fingers that the gripper fingers of the gripper finger pairs for gripping a bundle of bristles transversely to the bundle longitudinal direction are movable relative to each other so that the distance between these gripping fingers is reduced, and that the gripper finger pairs Grasp the bristle bundle so that between adjacent: gripper finger pairs at least one band of the bristle bundle is arranged.
Die erfindungsgemäße Übergabestation ist zur Übergabe von Borstenfilamenten an ein Magazin bestimmt, welche Borstenfilamente der Übergabestation in Borstenbündeln zugeführt werden. Dabei werden die Borstenfilamente eines Borstenbündels regelmäßig mittels wenigstens einem Band zusammengefasst . In dem Magazin werden die Borstenfilamente anschließend ungebündelt bevorratet. Die erfindungsgemäße Übergabestation hat zumindest zwei Paare von Greiffingern, welche Greiffinger-Paare in Bündellängsrichtung voneinander beabstandet sind. Die Greiffinger der Greiffinger-Paare sind derart relativ zueinander bewegbar, dass der Abstand dieser Greiffinger verringert werden kann, um zwischen den Greiffingern eines jeden Greiffinger-Paares die Borstenfilamente locker einzuspannen bzw. zu halten. Dabei wird das bereitgestellte Borstenbündel derart ergriffen, dass zwischen benachbarten Greiffinger-Paaren wenigstens ein Band des Borstenbündels angeordnet ist. Die erfindungsgemäße Übergabestation hat wenigstens einen Bandöffner, der zum Öffnen des wenigstens einen Bandes eines von den Greiffinger-Paaren ergriffenen Borstenbündels bestimmt ist. Die in Borstenlängserstreckung voneinander beabstandeten Greiffinger-Paare erlauben das Entbündeln der bündelweise gelieferten Borstenfilamente , wodurch eine automatisierte Übergabe der Borstenfilamente an ein, die Borsten- filamente anschließend ungebündelt bevorratendes Magazin möglich wird. Um ein zwischen den Greif finger-Paaren gehaltenes Borstenbündel von dem wenigstens einen, das Borstenbündel umgreifenden Band zu befreien, ist es vorteilhaft, wenn die Übergabestation wenigstens einen Bandöffner hat, zum Öffnen des wenigstens einen Bandes eines von den Greif finger-Paaren ergriffenen Borstenbündels . The transfer station according to the invention is intended for the transfer of bristle filaments to a magazine, which bristle filaments of the transfer station are supplied in bristle bundles. The bristle filaments of a bundle of bristles are regularly combined by means of at least one band. In the magazine, the bristle filaments are then stored unbundled. The transfer station according to the invention has at least two pairs of gripper fingers, which gripper finger pairs are spaced apart in the bundle longitudinal direction. The gripper fingers of the gripper finger pairs are movable relative to one another in such a way that the spacing of these gripper fingers can be reduced in order to loosely clamp or hold the bristle filaments between the gripper fingers of each gripper finger pair. In this case, the bundle of bristles provided is grasped such that at least one band of the bristle bundle is arranged between adjacent gripper finger pairs. The transfer station according to the invention has at least one band opener which is intended to open the at least one band of a bundle of bristles grasped by the gripper finger pairs. The gripper finger pairs which are spaced apart from one another in the longitudinal direction of the bristle allow the bundle-like bristle filaments to be unbundled, whereby an automated transfer of the bristle filaments to a magazine which subsequently stores the bristle filaments in an unbundled manner becomes possible. In order to free a held between the gripping finger pairs bristle bundles of the at least one, the bristle bundle encompassing band, it is advantageous if the transfer station has at least one band opener, for opening the at least one band of a gripping fingers pairs fingered bristle bundle.

In this case, preferred embodiment forms according to the invention provide that the at least one band opener is designed as a knife, as a pair of scissors or as a pliers.
Um das derart geöffnete Band aus dem Bereich der Borstenfila- mente entfernen zu können, ist es vorteilhaft, wenn dem wenigstens einen Bandöffner ein Bandgreifer zugeordnet ist, der das vom Bandöffner zu öffnende Band ergreift. Nach dem Öffnen des Bandes durch den Bandöffner kann der Bandgreifer das Band seitlich an den Borstenf ilamenten vorbei bewegen und entfernen. In order to be able to remove the band thus opened from the region of the bristle filaments, it is advantageous if the at least one band opener is assigned a band gripper which grips the band to be opened by the band opener. After opening the tape through the tape opener, the tape gripper can move the tape past the bristle filaments and remove it.
Statt eines solchen Bandgreifers sieht eine andere vorteilhafte Ausführungs form gemäß der Erfindung vor, dass dem wenigstens einen Bandöffner eine Saugeinrichtung zugeordnet ist, die das vom Bandöffner geöffnete Band ansaugt und mittels eines Saugstromes abtransportiert. Instead of such a belt gripper provides another advantageous embodiment form according to the invention that the at least one band opener is associated with a suction device, which sucks the band opener open band and transported away by means of a suction flow.
Um beim Öffnen des Bandes mit Hilfe des Bandöffners nicht im Wege zu stehen, ist es zweckmäßig, wenn der Bandgreifer oder die Saugeinrichtung auf der einem Bandöffner abgewandten Seite eines Borstenbündels angeordnet ist. In order not to stand in the way of opening the tape by means of the tape opener, it is expedient if the tape gripper or the suction device is arranged on the side facing away from a band opener of a bristle bundle.
Möglich ist es, dass die Greif finger-Paare der Übergabestation das betreffende Borstenbündel in einer Position ergreifen, in welcher Position die Borstenfilamehte mit ihrer Borsten- Längserstreckung etwa in horizontaler Richtung orientiert sind. Bevorzugt wird jedoch eine Ausführungsform, bei welcher die Greif finger-Paare das betreffende Borstenbündel in einer Position ergreifen, in der die Borsten-Längsrichtung etwa in vertikaler Richtung orientiert ist. It is possible that the gripping finger pairs of the transfer station grab the respective bristle bundle in a position in which position the bristle filament with its bristle Longitudinal extent are oriented approximately in the horizontal direction. However, an embodiment is preferred in which the gripping finger pairs grasp the respective bristle bundle in a position in which the bristle longitudinal direction is oriented approximately in the vertical direction.
Da selbst aus den von zumindest einem Band umgriffenen Borstenbündel einzelne Borstenfilamente hindurchfallen und verloren gehen können, ist es vorteilhaft, wenn die Borstenbündel im Bereich der Greif finger-Paare mit ihrer einen Bündel -St irnseite auf einer Auflage angeordnet sind. Auf diese Weise wird sichergestellt, dass auch nicht ein einziges Borstenfilament eines von den Greif finger-Paaren gehaltenen Borstenbündels nach unten hindurch fallen und verloren gehen kann. Since individual bristle filaments fall through and can be lost even from the bundles of bristles encompassed by at least one band, it is advantageous if the bristle bundles are arranged in the region of the gripping finger pairs with their one bundle on the inside. In this way it is ensured that not a single bristle filament held by the gripping finger pairs bristle bundle fall down and can be lost.
Um die Borstenbündel im Bereich der Greif finger-Paare zu bewegen und um die Borstenbündel der Übergabestation zuzuführen, ist es vorteilhaft, wenn die Auflage als Förderband ausgebildet ist, welches Förderband die Borstenbündel den Greiffinger-Paaren zuführt . In order to move the bristle bundles in the area of the gripping finger pairs and to feed the bristle bundles of the transfer station, it is advantageous if the support is designed as a conveyor belt, which conveyor belt supplies the bristle bundles to the gripper finger pairs.
Um die noch zwischen den Greif finger- Paaren gehaltenen und gegebenenfalls bereits von dem zumindest einen Band befreiten Borstenfilamente transportieren und in Richtung zum Magazin bewegen zu können, kann es vorteilhaft sein, wenn die auf der Auflage befindlichen Borstenbündel an ihrer der Auflage abgewandten Bündel -Stirnseite mittels einer Saugplatte erfassbar sind. In order to transport the still held between the gripping finger pairs and possibly already freed from the at least one band bristle filaments and to move in the direction of the magazine, it may be advantageous if the bristle bundles located on the support on its side facing away from the support bundle front can be detected by a suction plate.
Dabei sieht eine bevorzugte Aus führungs form gemäß der Erfindung vor, dass die Saugplatte ein Tressengewebe aufweist, welches von dem Saugstrom eines Sauggebläses durchströmbar ist. Ein solches Tressengewebe weist eine derart feine Struktur auf, das die Borstenfilamente zwar nicht durch das Tressengewebe hindurchgesaugt werden, sondern stattdessen im Saugstrom des Sauggebläses am Tressengewebe hängen bleiben. Dieser Saugstrom kann das Tressengewebe durch die Öffnungen passieren, die durch die Gewebestruktur gebildet sind. In this case, a preferred embodiment of the invention provides for the suction plate to have a weave fabric, through which the suction flow of a suction blower can flow. Such a weave fabric has such a fine structure that Although the bristle filaments are not sucked through the weave tissue, but instead remain caught in the suction flow of the suction fan on the tissue tissue. This suction flow can pass the tissue of tissue through the openings formed by the tissue structure.
Um die Borstenbündel geordnet entbündeln: und die zunächst noch bündelweise zugeführten Borstenfilamente an das Magazin weitergeben zu können, ist es vorteilhaft, wenn die Borstenbündel auf der als Förderband ausgebildeten Auflage auf Abstand gehalten sind und wenn dazu zumindest ein Borstenbündel -Stopper vorgesehen ist, der zwischen einer : Ruheposition und einer in den. Förderweg des Förderbandes vorstehenden Halteposition verfahrbar oder verschwenkbar ist. Dieser zumindest eine Borstenbündel - Stopper, der mit wenigstens einer Lichtschranke oder dergleichen optischer Borstenbündel -Erfassung in Steuerverbindung steht, vermag den Abstand zwischen den, auf der Auflage befindlichen Borstenbündeln auf den gewünschten Abstand zu strecken. Um die von dem wenigstens einen Band befreiten Borstenfilamente an das Magazin weitergeben zu können, ist es zweckmäßig, wenn in den, zwischen in Bündel -Längsrichtung beabstandeten Greiffinger-Paaren angeordneten Zwischenraum ein, die Borstenfila- mente übernehmendes weiteres Greiffinger-Paar einfahrbar ist. Während die derart vom Band befreiten Borstenfilamente an der Saugplatte kleben, werden die an der Saugplatte haftenden Borstenfilamente durch das wenigstens eine weitere Greiffinger-Paar zusammengehalten, das in den Zwischenraum der in Bündel-Längsrichtung beabstandeten, oben beschriebenen Greiffinger-Paare einfahrbar ist . In order to unbundle the bundles of bristles in an orderly manner: and to be able to pass on the initially bundled bristle filaments to the magazine, it is advantageous if the bristle bundles are kept at a distance on the support designed as a conveyor belt and if at least one bristle bundle stopper is provided between them one : resting position and one in the. Conveyor of the conveyor belt protruding holding position is movable or pivoted. This at least one bristle bundle stopper, which is in control connection with at least one light barrier or the like optical bristle bundle detection, is able to stretch the distance between the bristle bundles located on the support to the desired distance. In order to be able to pass on the bristle filaments freed from the at least one band to the magazine, it is expedient if a further gripper finger pair which can take over the bristle filaments is retractable in the intermediate space arranged between gripper longitudinally spaced in bundle longitudinal direction. While the thus liberated from the band bristle filaments stick to the suction plate, the adhering to the suction plate bristle filaments are held together by the at least one further gripper pair, which is retractable into the space of the longitudinally spaced in bundle longitudinal direction, described above Greiffinger pairs.
Um den durch wenigstens ein Band zusammengehaltenen Borsten- filamenten und erst Recht den von dem wenigstens einen Band befreiten Borstenfilamenten eine gewisse Außenkoritur zu geben, die das Handling dieser Borstenfilamente erleichtert, ist es vorteilhaft, wenn an zumindest einem Greiffinger wenigstens eines Greiffinger-Paares mindestens eine, über den Greiffinger seitlich zu dem benachbarten Greiffinger des Greiffinger- Paares vorstehende Längsbegrenzung vorgesehen ist . In order to give the bristle filaments held together by at least one band and, more particularly, the bristle filaments freed from the at least one band, to give them a certain external finish. which facilitates the handling of these bristle filaments, it is advantageous if at least one gripper finger of at least one gripper finger pair at least one, over the gripper fingers laterally to the adjacent gripper finger of the gripper finger pair projecting longitudinal limit is provided.
Dabei sieht eine bevorzugte Ausführungsform gemäß der Erfindung vor, dass zumindest eine Längsbegrenzung verstellbar am Greiffinger gehalten ist. In this case, a preferred embodiment according to the invention provides that at least one longitudinal limitation is adjustably held on the gripping finger.
Um die in der Übergabestation entbündelten Borstenfilamente dem Magazin zuführen und anschließend im Magazin bevorraten zu können, ist es vorteilhaft, wenn das Magazin zumindest eine Förderstrecke hat, in der die in vertikaler Richtung orientierten Borstenfilamente zwischen zwei Seitenleisten angeordnet sind. In order to feed the bundle filaments unbundled in the transfer station to the magazine and then to be able to store them in the magazine, it is advantageous if the magazine has at least one conveying path in which the bristle filaments oriented in the vertical direction are arranged between two side strips.
Das Einfädeln der Borstenfilamente in die durch zwei Seitenleisten begrenzte Förderstrecke wird erleichtert, wenn die zumindest eine Förderstrecke einen Einführbereich aufweist, in welchem sich der Abstand der die Förderstrecke begrenzenden Seitenleisten in Förderrichtung verringert . The threading of the bristle filaments into the conveying path delimited by two side strips is facilitated if the at least one conveying section has an insertion region in which the distance of the side strips delimiting the conveying path in the conveying direction is reduced.
Um die in einer Förderstrecke bevorraten Borstenfilamente in ihrer, in vertikaler Richtung orientierten Position zu halten und zu sichern, ist es zweckmäßig, wenn die in der zumindest einen Förderstrecke befindlichen Borstenfilamente mit wenigstens einem, seitlich über eine Seitenleiste vorstehenden und vorzugsweise entlang dieser Seitenleiste verfahrbaren Drücker gehalten sind. In order to hold and secure the bristle filaments stored in a conveying section in their vertically oriented position, it is expedient for the bristle filaments located in the at least one conveying section to have at least one pusher projecting laterally over a side strip and preferably movable along this side strip are held.
Dabei wird das Handling der entbündelten Borstenfilamente im Bereich der zumindest einen Förderstrecke noch erleichtert, wenn an jeder Seitenleiste ein seitlich vorstehender Drücker vorgesehen ist. In this case, the handling of the unbundled bristle filaments in the region of the at least one conveying section is made easier if on each side strip a laterally protruding pusher is provided.
Um die Borstenf ilamente in der Förderstrecke vorschieben und in Richtung beispielsweise zu einem StopfWerkzeug bewegen zu können, ist es vorteilhaft, wenn jeder Förderstrecke ein zwischen den Seitenleisten dieser Förderstrecke verfahrbarer Schieber zugeordnet ist. In order to be able to advance the bristle filaments in the conveying path and to be able to move in the direction, for example, to a stuffing tool, it is advantageous if each conveying path is assigned a slide movable between the side rails of this conveying path.
Das Handling der in vertikaler Richtung orientierten Borsten- f ilamente wird auch im Bereich der Förderstrecke des Magazins erleichtert und gesichert, wenn wenigstens ein Schieber zumindest zwei Schiebefinger hat, die derart voneinander beabstandet sind, dass die zumindest zwei Schiebefinger in Längserstreckung der Borstenfilamente beabstandet an diesen anlegbar sind. Bei dieser Aus führungs form weist der Schieber zumindest zwei Schiebefinger auf, die in Borstenlangserstreckung mit Abstand voneinander an den benachbarten Borstenf ilamenten angreifen. The handling of the bristle filaments oriented in the vertical direction is also facilitated and secured in the region of the conveying path of the magazine if at least one slider has at least two sliding fingers which are spaced apart from one another so that the at least two sliding fingers are spaced apart in the longitudinal extent of the bristle filaments can be applied. In this embodiment, the slide has at least two sliding fingers, which engage in bristle elongation at a distance from one another at the adjacent bristle filaments.

1 dargestellt, die zur Übergabe von bündelweise zugeführten Borstenfilamenten an ein die Borstenfilamente anschließend umgebündelt bevorratendes Magazin 2 bestimmt ist. Solche Bors- tenfilamente werden regelmäßig in Borstenbündeln 3 angeboten, in denen die Borstenbündel durch wenigstens ein Band und insbesondere wenigstens ein Gummiband 4 zusammengehalten sind. Das Magazin 2 kann beispielsweise einem Stopfwerkzeug 5 einer Bürstenherstellungsmaschine vorgeschaltet sein, welches Stopfwerkzeug 5 eine Teilmenge von Borstenfilamenten aus dem im Magazin1, which is intended for the transfer of bundle-supplied bristle filaments to a bristle filaments then bundled stocking magazine 2. Such bristle filaments are regularly offered in bristle bundles 3 in which the bristle bundles are held together by at least one band and in particular at least one rubber band 4. The magazine 2 may, for example, be preceded by a stuffing tool 5 of a brush-making machine, which stuffing tool 5 is a subset of bristle filaments from the magazine in the magazine

The brush body 6 is positioned in front of the stuffing tool 5 by means of a positioning device 7.
In den Figuren 1, 2 und 5 bis 8 ist erkennbar, dass die Übergabestation 1 zumindest zwei, in Längsrichtung der Borstenbündel voneinander beabstandete Paare 8, 9 von Greif fingern 10, 11; 12, 13 hat. Dabei sind die Greif finger 10, 11; 12, 13 der Greifinger-Paare 8, 9 zum Ergreifen eines zugeführten Borstenbündels 3 quer zur Bündel -Längsrichtung derart relativ zueinander bewegbar, dass der Abstand der Greiffinger 10,11; 12, 13 zueinander verringert wird. Wird der Abstand der Greif finger 10, 11; 12, 13 eines jeden Greif finger-Paares 8, 9 verringert, wird das Borstenbündel 3 von der ursprünglichen, im Querschnitt runden und in Figur 10 links abgebildeten Form in die in Figur 1.0 rechts gezeigte, nun längs gestreckte Form verformt. Dabei ergreifen die Greif finger-Paare 8, 9 das Borstenbündel 3 derart, dass das die Borstenf ilamente noch zusammenhaltende Gummiband 4, das vorzugsweise im Querschnitt unrund und vorzugsweise etwa rechteckig ist, zwischen den Greiffingern 10, 11; 12, 13 benachbarte Greif finger-Paare angeordnet ist. In Figures 1, 2 and 5 to 8 it can be seen that the transfer station 1 at least two, spaced apart in the longitudinal direction of the bristle bundles pairs 8, 9 of gripping fingers 10, 11; 12, 13 has. The gripping fingers 10, 11; 12, 13 of the gripper pairs 8, 9 for gripping a supplied bristle bundle 3 transversely to the bundle longitudinal direction movable relative to each other such that the distance of the gripping fingers 10,11; 12, 13 is reduced to each other. If the distance between the gripping fingers 10, 11; 12, 13 of each gripping finger pair 8, 9 reduced, the bristle bundle 3 is deformed from the original, round in cross-section and shown in Figure 10 on the left in the form shown in Figure 1.0 right, now elongated shape. In this case, the gripping finger pairs 8, 9 take the bristle bundle 3 such that the bristles ilamente still cohesive rubber band 4, which is preferably non-circular in cross-section and preferably approximately rectangular, between the gripping fingers 10, 11; 12, 13 adjacent gripping finger pairs is arranged.
In Figur 2 ist erkennbar, dass die Borstenbündel 3 mit ihrer einen Bündel -St irnseite auf einer Auflage stehen, die hier als Förderband 14 ausgebildet ist. Die Borstenbündel 3 werden der Übergabestation 1 auf dem Förderband 14 zugeführt. Um die Borstenbündel 3 geordnet lösen und weiterbewegen zu können, werden die Borstenbündel 3 auf dem Förderband 14 auf Abstand gebracht. Dazu ist zumindest ein Borstenbündel -Stopper 15, 16 vorgesehen, der zwischen einer Ruheposition und einer in den Förderweg des Förderbandes 14 vorstehenden Halteposition verfahrbar oder verschwenkbar ist. Die jeweils mit einer Lichtschranke in Steuerverbindung stehenden und hier beidseits des Förderbandes 14 an- geordneten Paare von Borstenbündel -Stoppern 15, 16 sorgen dafür, dass die Borstenbündel 3 auf Abstand gehalten werden. Die auf dem Förderband 14 stehenden Borstenbündel 3 werden den beiden Greif finger-Paaren 8, 9 zugeführt, welche Greif finger-Paare in Bündel -Längsrichtung voneinander beabstandet sind. Die Greiffinger 10, 11; 12, 13 der Greiffinger-Paare 8, 9 sind quer zur Bündel -Längsrichtung der derart relativ zueinander verfahrbar oder bewegbar, dass der Abstand dieser Greif finger 10, 11; 12, 13 verringert wird und ein zwischen den Greif fingern 10, 11; 12, 13 der Greiffinger-Paare 8, 9 befindliches Borstenbün- del sicher gehalten ist. Dabei ergreifen die Greif finger-Paare 8, 9 das Borstenbündel 3 derart, dass zwischen benachbarten Greif finger-Paaren 8, 9 das wenigstens eine, die Borstenf ila- mente eines Borstenbündels 3 zusammenhaltende Gummiband 4 angeordnet' ist . It can be seen in FIG. 2 that the bristle bundles 3, with their one bundle side, stand on a support, which is designed here as a conveyor belt 14. The bristle bundles 3 are supplied to the transfer station 1 on the conveyor belt 14. In order to solve the bristle bundles 3 ordered and continue to move, the bristle bundles 3 are placed on the conveyor belt 14 at a distance. For this purpose, at least one bristle bundle stopper 15, 16 is provided, which can be moved or pivoted between a rest position and a holding position protruding into the conveying path of the conveyor belt 14. Each in control connection with a light barrier and here on both sides of the conveyor belt 14. arranged pairs of bristle bundle stoppers 15, 16 ensure that the bristle bundles 3 are kept at a distance. The standing on the conveyor belt 14 bristle bundles 3 are the two gripping finger pairs 8, 9 fed, which gripping finger pairs are spaced apart in bundle longitudinal direction. The gripping fingers 10, 11; 12, 13 of the gripper finger pairs 8, 9 are transversely to the bundle longitudinal direction of such relative to each other movable or movable, that the distance of this gripping fingers 10, 11; 12, 13 is reduced and a finger between the gripping 10, 11; 12, 13 of the gripper finger pairs 8, 9 located bristle bundle is held securely. The gripping finger pairs 8, 9 grip the bristle bundle 3 in such a way that between adjacent gripping finger pairs 8, 9 the at least one rubber band 4 holding together the bristle filaments of a bristle bundle 3 is arranged.
In Figur 2 ist angedeutet, dass die Übergabestation wenigstens einen Bandöffner 17 hat, der hier als Schere ausgestaltet ist. Der Bandöffner 17 ist zum Öffnen des wenigstens einen Gummibandes 4 vorgesehen, welches das von den Greif finger-Paaren 8, 9 ergriffene Borstenbündel umgibt. Während der als Schere ausgebildete Bandöffner 17 das wenigstens eine Gummiband 4 durchtrennt, wird das Gummiband 4 auf der dem Bandöffner 17 abgewandten Seite des Borstenbündels 3 von einem zangenartigen Bandgreifer 18 gehalten, der anschließend das aufgeschnittene Gummiband 4 am Borstenbündel vorbei zieht und abtransportiert. Anschließend wird das Gummiband 4 in einen Abfallbehälter geworfen. Statt des Bandgreifers 18 kann auch eine Direktabsau- gung des aufgeschnittenen Gummibandes 4 vorgesehen sein. Bei dem Bandöffner 17 und dem Bandgreifer 18 ist an der Spitze der Scheren- bzw. Zangenarme ein kreisrunder Filamentverdränger 19 vorgesehen, der dafür sorgt, dass nicht zusätzlich zum Gummiband 4 auch einzelne Borstenf ilamente abgeschnitten oder ge- klemmt werden. In Figure 2 it is indicated that the transfer station has at least one band opener 17, which is designed here as a pair of scissors. The band opener 17 is provided for opening the at least one rubber band 4, which surrounds the grip of the gripping finger pairs 8, 9 bristle bundles. While trained as a scissors band opener 17 which cuts through at least one rubber band 4, the rubber band 4 is held on the band opener 17 side facing away from the bristle bundle 3 by a pincer-like band gripper 18, which then pulls the cut rubber band 4 on bristle bundle over and transported away. Subsequently, the rubber band 4 is thrown into a waste container. Instead of the band gripper 18, a direct suction of the cut rubber band 4 can also be provided. In the band opener 17 and the band gripper 18, a circular filament displacer 19 is provided at the tip of the scissors or pliers arms, which ensures that individual bristle filaments are not cut off in addition to the rubber band 4 or not. be stuck.
In Figur 3 wird das Borstenbündel 3 in einem nachfolgenden Verfahrensschritt verformt. Beim Zusammenführen der Greiffinger 10, 11; 12, 13 wird das im Querschnitt zunächst noch runde Borstenbündel 3 derart verformt, dass es im Querschnitt die in Figur 10 gezeigte längs gestreckte Form annimmt. Bevor diese Umformung erfolgt, wird eine Abdeckplätte 20 derart verschwenkt oder bewegt, dass sie über dem Borstenbündel 3 gehalten ist, um ein Herausspringen auch nur eines einzelnen Borsten ilaments zu verhindern. Die Umformung der durch die Greiffinger-Paare 10, 11; 12, 13 noch bündelweise zusammengehaltenen Borstenfilamente erfolgt durch die beiden Greiffinger-Paare 8, 9. In FIG. 3, the bristle bundle 3 is deformed in a subsequent method step. When merging the gripping fingers 10, 11; 12, 13, the bristle bundle 3, which is initially round in cross section, is deformed in such a way that, in cross section, it assumes the longitudinally extended shape shown in FIG. Before this transformation takes place, a cover plate 20 is pivoted or moved in such a way that it is held over the bristle bundle 3, in order to prevent it from jumping out even of a single bristle filament. The transformation of the by the gripper finger pairs 10, 11; 12, 13 bundle filaments held together in bundles is carried out by the two gripper finger pairs 8, 9.
In Figur 4 ist angedeutet, dass in den zwischen den Greiffin- ger-Paaren 8, 9 in Bündel -Längsrichtung vorgesehenen Zwischenraum ein weiteres Greiffinger-Paar 21 mit Greiffingern 22, 23 einfahrbar ist, welches die nun bereits nicht mehr durch ein Gummiband 4 gehaltenen Borstenfilamente übernimmt. Gleichzeitig wird über die der Auflage abgewandte Stirnseite der Borsten- filamente eine Saugplatte 24 bewegt, welche die Borstenfilamente an ihren Enden durch einen Saugstrom hält. Diese Saugplatte 24 weist ein Tressengewebe auf, dass derart fein ist, das Borstenfilamente nicht durch die Saugplatte hindurch angesaugt werden können. FIG. 4 indicates that a further gripper finger pair 21 with gripper fingers 22, 23 can be inserted in the intermediate space provided between the gripper finger pairs 8, 9 in the bundle longitudinal direction, which now is no longer held by a rubber band 4 Borstenfilamente takes over. At the same time, a suction plate 24, which holds the bristle filaments at their ends by means of a suction flow, is moved over the end face of the bristle filaments facing away from the support. This suction plate 24 has a Tissue fabric that is so fine that bristle filaments can not be sucked through the suction plate.
In Figur 5 hat das Greiffinger-Paar 21 und die Saugplatte 24 die vom Gummiband befreiten Borstenfilamente aus der durch das Förderband 14 und die Greiffinger-Paare 8, 9 gebildeten Zuführung entnommen, um diese Borstenfilamente nun zum Magazin zu bewegen. In Figur 7 ist der Aufbau eines Greiffinger-Paares anhand der Greiffinger-Paare 8, 9 im Detail gezeigt. Wie zu erkennen ist, ist an jedem Greiffinger beidseits der Borstenfila- mente jeweils eine über den Greiffinger seitlich zu dem benachbarten Greiffinger des Greif finger-Paares 8 oder 9 vorstehende Längsbegrenzung 25 vorgesehen. Diese Längsbegrenzung, die an dem ihr zugeordneten Greiffinger verschiebbar oder verstellbar gehalten ist, weist zum die Längsbegrenzung 25 tragenden Greif - finger einen stumpfen Winkel, beispielsweise einen Winkel von 100 Grad, auf. Auch im Bereich der Greif finger-Paare 8, 9 sind Lichtschranken: 26 vorgesehen, welche das Vorhandensein der Borstenf ilamente signalisieren. In FIG. 5, the gripper finger pair 21 and the suction plate 24 have removed the bristle filaments freed from the rubber band from the feeder formed by the conveyor belt 14 and the gripper finger pairs 8, 9 in order to move these bristle filaments to the magazine. FIG. 7 shows the structure of a gripper finger pair with reference to the gripper finger pairs 8, 9 in detail. As can be seen, on each gripper finger on both sides of the bristle filament Mente in each case one on the gripper fingers laterally to the adjacent gripping fingers of the gripping finger pair 8 or 9 projecting longitudinal boundary 25 is provided. This longitudinal boundary, which is held displaceably or adjustably on the gripping finger assigned to it, has an obtuse angle, for example an angle of 100 degrees, with respect to the gripping finger which bears the longitudinal boundary 25. Also in the area of the gripping finger pairs 8, 9 are provided light barriers: 26 which signal the presence of the bristle filaments.
Das Greif finger-Paar 21 und die Saugplatte 24 bewegen die Borstenfilamente anschließend zu dem in Figur 1 bis 15 gezeigten Magazin 2. Das Magazin 2 hat zumindest eine Förderstrecke 27, in welcher Förderstrecke 27 die von den Bändern 4 befreiten Borstenf ilamente bevorratet werden. Die Förderstrecke 27 hat zwei Seitenleisten 28, 29, die voneinander beabstandet sind und welche die in Borstenlängsrichtung orientierten Borstenfila- mente führen. The gripping finger pair 21 and the suction plate 24 then move the bristle filaments to the magazine 2 shown in FIGS. 1 to 15. The magazine 2 has at least one conveying path 27 in which conveying path 27 the bristle filaments freed from the belts 4 are stored. The conveying path 27 has two side strips 28, 29, which are spaced apart from one another and which guide the bristle filaments oriented in the longitudinal direction of the bristle.
Die Förderstrecke 27 weist einen Einführbereich 30 auf, in welchem sich der Abstand der die Förderstrecke 27 begrenzenden Seitenleisten 28, 29 in Förderrichtung verringert. In den Figuren 11 und 13 werden die am Greif finger-Paar 21 und an der Saugplatte 24 gehaltenen Borstenfilamente im Einführbereich 30 zwischen den beiden Seitenleisten 28, 29 in die Förderstrecke 27 eingeschoben. Auch ein direktes Einlegen von oben zwischen die Seitenleisten 28, 29 ist möglich, wenn der Abstand zwischen den Seitenleisten 28, 29 größer als der Querschnitt der in länglicher Form zusammengehaltenen Borstenf ilamente ist. The conveying path 27 has an insertion region 30, in which the distance between the side rails 28, 29 delimiting the conveying path 27 is reduced in the conveying direction. In FIGS. 11 and 13, the bristle filaments held on the gripping finger pair 21 and on the suction plate 24 are inserted into the conveying path 27 in the insertion region 30 between the two side strips 28, 29. A direct insertion from above between the side strips 28, 29 is possible if the distance between the side strips 28, 29 is greater than the cross section of the bristle filaments held together in an elongated form.
In der Förderstrecke 27 werden die Borstenf ilamente mit wenigstens einem, seitlich über eine Seitenleiste 28, 29 vorstehenden und entläng dieser Seitenleiste 28, 29 verfahrbaren Drücker ge- halten. In den Figuren 11 und 13 ist zu erkennen, dass die Seitenleiste 28 zwei Drückerkanäle 31 hat, in denen jeweils ein Drücker 32 verfahrbar ist, und dass die an der Seitenleiste 28 verfahrbaren und in einer Halteposition in die Förderstrecke 27 einschwenkbaren Drücker 32 in Borsten-Längsrichtung voneinander beabstandet sind. In the conveying path 27, the bristle filaments are provided with at least one pusher which can be moved laterally over a side strip 28, 29 and extends along this side strip 28, 29. hold. In FIGS. 11 and 13, it can be seen that the side strip 28 has two pusher channels 31, in each of which a pusher 32 can be moved, and that the pusher 32, which can be moved on the side strip 28 and can be pivoted into the conveying path 27 in a holding position, is in bristle shape. Lengthwise spaced from each other.
Der Förderstrecke 27 ist auch ein Schieber 33 zugeordnet, der zwischen den Seitenleisten 28, 29 der Förderstrecke 27 verfahrbar ist und die dort bevorrateten Borstenf ilamente zusammen- presst. Dieser Schieber 33 hat hier zumindest zwei, in Borsten- Längsrichtung voneinander beabstandete Schieberfinger 34, 35, die in den Seitenleisten 28, 29 in Schieberkanälen 36 geführt sind. Im Einführbereich 30 sind die Schieberkanäle 36 trichterartig ausgebildet, um die Schieberfinger 34, 35 erfassen und aufnehmen zu können. The conveying path 27 is also associated with a slide 33 which is movable between the side rails 28, 29 of the conveying path 27 and compresses the bristle filaments stored there. Here, this slide 33 has at least two slide fingers 34, 35 which are spaced apart from one another in the longitudinal direction of the bristles and which are guided in slide channels 36 in the side rails 28, 29. In the insertion region 30, the slide channels 36 are funnel-shaped, in order to detect and accommodate the slide fingers 34, 35 can.
Die in Figur 14 in der Förderstrecke 27 platzierten Borsten- filamente werden dort bis zu einer Bodenplatte der Förderstrecke 27 abgesetzt und gegen die Drücker 32 geschoben. Um hier den sicheren Halt der Borstenf ilamente sicherzustellen, wird der Schieber 33 von hinten an den Borstenbund angelegt. Anschließend kann das Greif finger-Paar 21 entfernt werden, so dass der Schieber 33 den Borstenbund nun gegen die beiden Drücker 32 presst. Die beiden Drücker werden seitlich entfernt, um hinter dem: neu zugeführten Borstenbund, parallel zum Schieber 33, wieder erneut in ihre Halteposition eingeschwenkt zu werden, in der nun der gesamte Borstenvorrat von den Drückern 32 zusammengehalten wird. The bristle filaments placed in the conveying path 27 in FIG. 14 are deposited there as far as a bottom plate of the conveying path 27 and pushed against the pushers 32. In order to ensure the secure hold of the bristle filaments here, the slider 33 is applied to the bristle collar from behind. Subsequently, the gripping finger pair 21 can be removed, so that the slider 33 now presses the bristle collar against the two pushers 32. The two pushers are removed laterally to be pivoted back into their holding position behind the : newly supplied bristle collar, parallel to the slider 33, in which now the entire bristle supply is held together by the pushers 32.
In Figur 15 ist das Greif finger-Paar 21 und die Saugplatte 24 aus dem Bereich der Borstenf ilamente entfernt. In den Figuren 11 und 13 bis 15 ist angedeutet, dass der Förderstrecke 27 ein Tatscher 37 zugeordnet ist. Dieser Tatscher 37 ist in Borsten- Längsrichtung um einige Millimeter zwischen einer oberen und einer unteren Tatscher-Stellung bewegbar, wobei in der unteren Tatscher-Stellung die Borstenfilamente an ihren freien Borstenenden beaufschlagt werden. Durch die Beaufschlagung der in der Förderstrecke 27 bevorrateten Borstenfilamente soll verhindert werden, dass einzelne Borstenfilamente während der Fortbewegung in der Förderstrecke 27 sich nach oben bewegen.: Um ein derartiges Herausragen einzelner Borstenfilamente wirkungsvoll zu verhindern, ist es vorteilhaft, wenn der Tatscher 37 sich über den gesamten Bereich des in der Förderstrecke 27 bevorrateten Bors tenmaterials erstreckt. In Figure 15, the gripping finger-pair 21 and the suction plate 24 is removed from the area of the bristle filaments. In the figures 11 and 13 to 15 is indicated that the conveying path 27 a Tatscher 37 is assigned. This Tatscher 37 is movable in the bristle longitudinal direction by a few millimeters between an upper and a lower Tatscher position, wherein in the lower Tatscher position, the bristle filaments are acted upon at their free bristle ends. By acting on the bristle filaments stored in the conveying path 27, it is intended to prevent individual bristle filaments from moving upwards during travel in the conveying path 27. In order to prevent such a protrusion of individual bristle filaments effective, it is advantageous if the Tatscher 37 extends over the entire range of the stored in the conveying section 27 Bors board material.
