Description

Die Erfindung betrifft eine Bündelabnahmevorrichtung für eine Bürstenherstellungsmaschine. Bündelabnehmer entnehmen aus einem Borstenmagazin nacheinander einzelne Borstenbündel, um sie einer Bürstenherstellungsmaschine zuzuführen. Bei dem Bündelabnehmer handelt es sich im wesentlichen um einen Schieber, der an einer offenen Seite des Borstenmagazins hin und her gleitet und eine Bündelabnahmekerbe aufweist, in der sich beim Vorbeigleiten die das Bündel bildenden Borsten sammeln. Der Bündelabnehmer transportiert jedes abgetrennte Borstenbündel zu einer Verarbeitungsstation, beispielsweise einem Stopfwerkzeug, und wird dann zum Borstenmagazin zurückbewegt, um das nächste Borstenbündel abzutrennen. Bei jedem Arbeitshub des Bündelabnehmers wird so ein Borstenbündel abgetrennt.The invention relates to a bundle removal device for a brush-making machine. Bundle takers remove from a bristle magazine successively individual bristle bundles to supply them to a brush making machine. The bundle picker is essentially a slider that slides back and forth on an open side of the bristle magazine and has a bundle removal notch in which the bristles forming the bundle collect as it passes by. The bundle picker transports each severed bundle of bristles to a processing station, such as a tamping tool, and is then moved back to the bristle magazine to separate the next bundle of bristles. With each working stroke of the bundle pickup, a bundle of bristles is separated.

Das Profil der Bündelabnahmekerbe bestimmt die Menge der bei jedem Arbeitshub des Bündelabnehmers abgetrennten Borsten. Um mit einer Bündelabnahmevorrichtung Bündel mit unterschiedlichen Mengen von Borsten abtrennen zu können, kann die wirksame Tiefe der Bündelabnahmekerbe verändert werden, indem ein Teil des Profils mit einem Abdeckelement seitlich abgedeckt wird. Das Abdeckelement begrenzt dann die Tiefe, bis zu der die Borsten in die Bündelabnahmekerbe eindringen können, anstelle des Bodens dieser Kerbe. Eine Bündelabnahmevorrichtung mit einstellbarer wirksamer Tiefe der Bündelabnahmekerbe ist z.B. aus der DE 40 40 297 C2 oder der JP 2003 169 719 A bekannt. Mit einer solchen Vorrichtung können Borstenbündel unterschiedlichen Querschnitts für unterschiedliche Bürsten abgetrennt werden.The profile of the bundle removal notch determines the amount of bristles separated during each stroke of the bundle picker. In order to be able to separate bundles with different amounts of bristles with a bundle removal device, the effective depth of the bundle removal notch can be changed by laterally covering part of the profile with a cover element. The cover then limits the depth to which the bristles can penetrate into the bundle removal score instead of the bottom of that notch. A bundle removal device with adjustable effective depth of the bundle removal notch is eg from the DE 40 40 297 C2 or the JP 2003 169 719 A known. With such a device bristle bundles of different cross section for different brushes can be separated.

Eine Bündelabnahmevorrichtung für eine Bürstenherstellungsmaschine ist aus der DE 1 938 937 A bekannt. Diese Bündelabnahmevorrichtung umfasst zwei Borstenmagazine mit unterschiedlich dicken Borsten. Ein Bündelabnehmer, der als gemeinsamer Bündelabnehmer für beide Borstenmagazine ausgeführt ist, hat eine größere und eine kleinere Bündelabnahmekerbe. Jede Bündelabnahmekerbe ist einem Borstenmagazin zugeordnet. Um zu vermeiden, dass eine Abnahmekerbe mit den Borsten aus dem falschen Magazin befüllt wird, ist ein Abdeckelement für die Bündelabnahmekerben vorgesehen, das bei der ersten Hubbewegung des Bündelabnehmers eine der Abnahmekerben abdeckt. Das Abdeckelement wird mit einer Stellvorrichtung, die einen Hubzylinder aufweist, zwischen einer Abdeckstellung und einer Freigabestellung bewegt. Die Stellvorrichtung bewegt sich zwischen zwei Endstellungen.A bundle picking device for a brush manufacturing machine is known from DE 1 938 937 A known. This bundle picking device comprises two bristle magazines with different thickness bristles. A bundle taker, designed as a common bundle taker for both bristle magazines, has a larger and a smaller bundle take-off score. Each bundle removal notch is associated with a bristle magazine. In order to avoid that a picking notch is filled with the bristles from the wrong magazine, a covering element for the bundle removal notches is provided, which covers one of the picking notches during the first lifting movement of the bundle picker. The cover member is provided with an actuator having a lifting cylinder, between a Cover position and a release position moves. The adjusting device moves between two end positions.

Bei modernen Bürsten, insbesondere Zahnbürsten, kommt der Wunsch auf, Borstenbündel unterschiedlicher Querschnittsgröße und Querschnittsform in einem Borstenfeld nebeneinander anzuordnen. Die Herstellung solcher Bürsten ist aufwendig, da sie mit den verfügbaren, schnell und rationell laufenden Bürstenherstellungsmaschinen nicht produziert werden können.In modern brushes, in particular toothbrushes, the desire comes to arrange bristle bundles of different cross-sectional size and cross-sectional shape in a bristle field next to each other. The preparation of such brushes is expensive because they can not be produced with the available, fast and efficient brush making machines.

Die erfindungsgemäße Bündelabnahmevorrichtung ist in der Lage, bei jedem Arbeitshub die wirksame Tiefe der Bündelabnahmekerbe zu variieren und dabei mit modernen, schnell laufenden Bürstenherstellungsmaschinen Schritt zu halten. Dies wird durch eine Bündelabnahmevorrichtung nach Anspruch 1 erreicht. Es sind Stellvorrichtungen verfügbar, die den erforderlichen geringen Verstellhub schnell, präzise und reproduzierbar ausführen können. Wichtig ist dabei auch eine starre Kopplung zwischen dem Abdeckelement und der Stellvorrichtung.The bundle picking device according to the present invention is capable of varying the effective depth of the bundle picking notch with each working stroke while keeping pace with modern, high speed brush making machines. This is achieved by a bundle picking device according to claim 1. There are adjusting devices available that can perform the required small Verstellhub fast, accurate and reproducible. Important is also a rigid coupling between the cover and the actuator.

Der Bündelabnehmer kann in herkömmlicher Weise entlang einem Kreisbogen gekrümmt und um eine feste Achse verschwenkbar sein.The bundle pickup may be curved in a conventional manner along a circular arc and pivotable about a fixed axis.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der folgenden Beschreibung mehrerer Ausführungsformen unter Bezugnahme auf die Zeichnungen. In den Zeichnungen zeigen:

  • Figur 1 eine schematische Draufsicht einer Bündelabnahmevorrichtung mit einem Stellantrieb zur Steuerung einer kreisbogenförmigen Abdeckschiene, mit der die wirksame Tiefe einer Bündelabnahmekerbe in einem Bündelabnehmer variiert wird, wobei diese Ausführungsform nur der Erläuterung dient und nicht unter den Schutzumfang des Patents fällt;
  • Figur 2 eine vergrößerte Detailansicht aus Figur 1;
  • Figur 3 eine Draufsicht einer zweiten, ebenfalls nicht unter den Schutzumfang dieses Patents fallenden Ausführungsform der Bündelabnahmevorrichtung; und
  • Figur 4 eine erfindungsgemäße Ausführungsform der Bündelabnahmevorrichtung.
Further features and advantages of the invention will become apparent from the following description of several embodiments with reference to the drawings. In the drawings show:
  • FIG. 1 a schematic plan view of a bundle removal device with an actuator for controlling a circular arc cover rail, with which the effective depth of a bundle decrease notch is varied in a bundle pickup, this embodiment is only illustrative and does not fall within the scope of the patent;
  • FIG. 2 an enlarged detail view FIG. 1 ;
  • FIG. 3 a plan view of a second, also not falling within the scope of this patent embodiment of the bundle removal device; and
  • FIG. 4 an embodiment of the bundle removal device according to the invention.

Die in Figur 1 gezeigte Ausführungsform der Bündelabnahmevorrichtung hat einen kreisbogenförmig gekrümmten Bündelabnehmer 10, der um eine bezüglich des Maschinengestells einer Bürstenherstellungsmaschine feste Achse A verschwenkbar ist. Der Bündelabnehmer 10 hat in seiner Umfangsfläche eine Bündelabnahmekerbe 12, die in Figur 2 stark vergrößert gezeigt ist. Die Umfangsfläche des Bündelabnehmers 10 liegt an einer offenen Seite eines Borstenmagazins 14 an, in dem auf Länge geschnittene Borsten lose aufgenommen sind. Der Bündelabnehmer 10 ist um die Achse A mit einem Arbeitshub verschwenkbar, bei dem die Bündelabnahmekerbe 12 über die offene Seite des Borstenmagazins 14 verschoben wird, so daß sich die Bündelabnahmekerbe mit Borsten aus dem Borstenmagazin 14 füllt. Bei der Rückbewegung des Bündelabnehmers 10 werden die abgenommenen Borsten durch einen Schirm 16, der am Umfang des Bündelabnehmers 10 anliegt, in der Bündelabnahmekerbe 12 festgehalten. Die Figur 1 zeigt den Bündelabnehmer 10 in einer Übergabestellung, bei der das abgetrennte Borstenbündel aus der Bündelabnahmekerbe 12 an eine Arbeitsstation einer Bürstenherstellungsmaschine abgegeben wird.In the FIG. 1 Shown embodiment of the bundle removal device has a circular arc curved bundle pickup 10 which is pivotable about an axis A fixed relative to the machine frame of a brush making machine. The bundle picker 10 has in its peripheral surface a bundle removal notch 12, which in FIG. 2 is shown greatly enlarged. The peripheral surface of the bundle picker 10 abuts against an open side of a bristle magazine 14 in which bristles cut to length are loosely received. The bundle picker 10 is pivotable about the axis A with a power stroke in which the bundle removal notch 12 is slid over the open side of the bristle magazine 14 so that the bundle removal notch fills with bristles from the bristle magazine 14. During the return movement of the bundle picker 10, the removed bristles are held in the bundle removal notch 12 by a screen 16 which abuts the circumference of the bundle picker 10. The FIG. 1 shows the bundle picker 10 in a transfer position in which the separated bristle bundle is released from the bundle removal notch 12 to a workstation of a brush making machine.

Zur Veränderung der wirksamen Tiefe der Bündelabnahmekerbe 12 ist ein Abdeckelement in Form einer kreisbogenförmig gekrümmten Abdeckschiene 18 vorgesehen. Die Abdeckschiene 18 ist an einem starren Bügel angeschlossen, der aus zwei parallelen Stangen 20, 22 und einem diese verbindenden Steg 24 besteht. Über den Steg 24 ist der Bügel und mit ihm die Abdeckschiene 18 gelenkig an einer Pleuelstange 26 angeschlossen, die ihrerseits gelenkig an einem Kurbelarm 28 eines Drehantriebs 30 angeschlossen ist. Der Drehantrieb 30 ist am Maschinengestell der Bürstenherstellungsmaschine gelagert. Die Stangen 20, 22 des starren Bügels sind, wie mit einem Doppelpfeil in Figur 1 angedeutet, in Radialrichtung bezüglich der Achse A verschiebbar gelagert. Der Drehantrieb 30 bildet mit dem aus Kurbelarm 28 und Pleuelstange 26 gebildeten Kurbeltrieb einen Stellantrieb zur Bewegung der Abdeckschiene 18 über den starren Bügel, der aus den Stangen 20, 22 und dem Steg 24 gebildet ist. Dieser Stellantrieb, dessen Drehantrieb vorzugsweise durch einen Servomotor gebildet ist, ist in der Lage, die Abdeckschiene 18 sehr schnell, sehr genau und gut reproduzierbar relativ zu dem Bündelabnehmer 10 zu verschieben, wie in Figur 2 durch einen Doppelpfeil angedeutet. Durch diese Verschiebung gleitet die Abdeckschiene 18 seitlich über das Profil der Bündelabnahmekerbe 12, um deren wirksame Tiefe zu verändern. Die Figur 2 zeigt die Abdeckschiene 18 in einer mittleren Position, in der die Gesamttiefe der Bündelabnahmekerbe 12 etwa halbiert wird.To change the effective depth of the bundle removal notch 12, a cover element in the form of a circular arc curved cover rail 18 is provided. The cover rail 18 is connected to a rigid bracket, which consists of two parallel rods 20, 22 and a web 24 connecting them. About the web 24 of the bracket and with it the cover rail 18 is pivotally connected to a connecting rod 26, which in turn is pivotally connected to a crank arm 28 of a rotary drive 30. The rotary drive 30 is mounted on the machine frame of the brush manufacturing machine. The bars 20, 22 of the rigid strap are as with a double arrow in FIG. 1 indicated, slidably mounted in the radial direction with respect to the axis A. The rotary drive 30 forms with the crank mechanism formed from crank arm 28 and connecting rod 26 an actuator for moving the cover rail 18 via the rigid bracket, which is formed from the rods 20, 22 and the web 24. This actuator, whose rotary drive is preferably formed by a servo motor, is able to move the cover rail 18 very quickly, very accurately and in a well reproducible relative to the bundle pickup 10, as in FIG. 2 indicated by a double arrow. By this displacement, the cover rail 18 slides laterally over the profile of the bundle removal notch 12 to change its effective depth. The FIG. 2 shows the cover rail 18 in a middle position in which the total depth of the bundle removal notch 12 is approximately halved.

Die Figur 3 zeigt eine Ausführungsform der Bündelabnahmevorrichtung, bei der ein geradlinig verschiebbarer Bündelabnehmer 10a mit einer entsprechend geradlinigen Abdeckschiene 18a zusammenwirkt. Alle übrigen Bestandteile sind in gleicher Weise ausgebildet wie bei der Ausführungsform nach Figur 1 und sind daher mit gleichen Bezugszahlen bezeichnet. Die Bewegung der Abdeckschiene 18a erfolgt hier mit dem durch die Stangen 20, 22 und den Steg 24 gebildeten starren Bügel senkrecht zur Verschiebungsrichtung des Bündelabnehmers 10a, wie durch einen Doppelpfeil in Figur 3 angedeutet.The FIG. 3 shows an embodiment of the bundle removal device, in which a rectilinearly movable bundle picker 10a cooperates with a correspondingly rectilinear cover rail 18a. All other components are formed in the same manner as in the embodiment according to FIG. 1 and are therefore designated by the same reference numerals. The movement of the cover rail 18a takes place here with the rigid bracket formed by the rods 20, 22 and the web 24 perpendicular to the direction of displacement of the bundle picker 10a, as indicated by a double arrow in FIG. 3 indicated.

Bei der Bündelabnahmevorrichtung nach Figur 4 wirkt der Bündelabnehmer 10b mit einem Abdeckelement 18b zusammen, das von einem Ende eines zweiarmigen Hebels 19 gebildet ist, der am Bündelabnehmer 10b schwenkbar um eine Achse 21 gelagert ist. Das gegenüberliegende Ende des zweiarmigen Hebels 19 trägt einen Kurvenfolger in Form einer Rolle 32. Die Rolle 32 ist in einem Führungsbogen 34 geführt, der entsprechend der Form des Bündelabnehmers 10b gekrümmt und am Maschinengestell radial bezüglich der Achse A des Bündelabnehmers 10b verschiebbar geführt ist. Der Führungsbogen 34 ist über massive Stangen 36, 38 an einen Stellantrieb angekoppelt, der in gleicher Weise ausgebildet sein kann wie bei den zuvor beschriebenen Ausführungsformen. Die Rolle 32 wird bei der Schwenkbewegung des Bündelabnehmers 10b in dem Führungsbogen 34 zwangsgeführt. Die Schwenkstellung des zweiarmigen Hebels 19 wird durch den Radius bestimmt, auf den der Führungsbogen 34 relativ zur Achse A eingestellt ist. Die Schwenkstellung des zweiarmigen Hebels 19 bestimmt andererseits die Höhe des Abdeckelements 18b relativ zum Profilboden der Bündelabnahmekerbe 12b. Da durch die radiale Verstellung des Führungsbogens 34 die Schwenkstellung des Hebels 19 und mit ihm die Stellung des Abdeckelements 18b verändert wird, kann im Ergebnis die wirksame Tiefe der Bündelabnahmekerbe 12b variiert werden.Follow the bundle removal device FIG. 4 the bundle pickup 10b cooperates with a cover element 18b, which is formed by one end of a two-armed lever 19, which is mounted on the bundle picker 10b so as to be pivotable about an axis 21. The opposite end of the two-armed lever 19 carries a cam follower in the form of a roller 32. The roller 32 is guided in a guide arc 34 which is curved in accordance with the shape of the bundle picker 10b and slidably guided on the machine frame radially with respect to the axis A of the bundle picker 10b. The guide bow 34 is coupled via solid rods 36, 38 to an actuator, which may be formed in the same manner as in the embodiments described above. The roller 32 is forcibly guided in the pivoting movement of the bundle 10b in the guide sheet 34. The pivotal position of the two-armed lever 19 is determined by the radius to which the guide arc 34 is set relative to the axis A. On the other hand, the pivotal position of the two-armed lever 19 determines the height of the cover member 18b relative to the profile bottom of the bundle removal notch 12b. As a result of the radial adjustment of the guide arc 34, the pivoting position of the lever 19 and with it the position of the cover 18 b is changed, as a result, the effective depth of the bundle decrease notch 12 b can be varied.
