Definitions
- the invention relates to a machine or a machine station for applying a strip or strip-shaped edge material and for cutting this edge material to plate-shaped workpieces of the type specified in the preamble of claim 1 in more detail (see EP 0 578 199 A).
- the separation units are used for capping the edge material applied to the narrow side surfaces of the workpieces.
- An edge banding machine with which the edge material can be approached on the narrow side surfaces of the workpieces in the run, shows the patent DE 42 17 291 C1.
- the applied edge material is usually applied not only on its longitudinal sides but also in the direction of passage of the workpieces seen both at the front end of the relevant workpiece narrow side surface and at the rear end with protrusion, and these supernatants must be flush with the forward and forward in the rule Be capped behind the workpiece narrow sides.
- the trimming units are chop saws with rotating circular saw blades, which are not only delivered transversely to the passage direction of the workpieces, but are moved along during the copying process along a path in the direction of passage synchronously with the workpieces.
- the invention has for its object to provide a machine or a machine station of the type mentioned, in which for the at least one separation unit for capping the applied on the narrow sides of the workpiece edge material a construction space of short length in the workpiece passage direction is needed, the separation unit of the other for universal inputs or averages can be used on the edge material.
- the cutting of the edge material with a single or submerged knife edge can be done much faster than the cutting of the edge material than by means of a cutting saw blade.
- the entrainment of the cutting edge can be accomplished with the respective interface of the edge material applied to the workpiece narrow side surfaces by appropriate rotation of the knife body, further still at the interface of the stroke of the knife edge transverse to the workpiece passage direction corresponding to the projection of the circular arc on which the knife edge during cutting moves, can be used in the radial direction perpendicular to the workpiece passage direction for the depth of cut.
- Fig. 1 shows workpieces 1, which are conveyed on a conveyor chain 2 in the direction of arrow A.
- the one narrow side surfaces 3 of the workpieces 1 are arranged in alignment in the conveying direction so that an edge strip 4 can be applied thereto in passing on an edge banding unit.
- the Kantenanleimaggregat has a supply roll 5, from which the edge material 4 withdrawn and brought by means of pressure rollers 6 gluing to the narrow side surfaces 3 of the workpieces 1.
- a Kappmesser 7 may be provided to cut off a strip of predetermined length of the edge material 4, which is provided for the coating of a narrow side surface 3 of the workpieces 1.
- the workpieces 1 After passing the edge banding unit, the workpieces 1 pass through trimming units 8 which edge the edge material 4 on the coated narrow side surface 3 of the workpieces 1 flush with the upper and lower sides of the plate-shaped workpieces 1. Subsequently the workpieces 1 are passed on the conveyor chain 2 in a further pass on a rotary knife 9, which is arranged stationary on the passageway and will be described in more detail below.
- FIG. 2 shows in each case the amount C and D by which the edge material 4 projects beyond the narrow sides of the workpiece 26 lying in the conveying direction of the workpieces 1 and narrow sides of the workpiece 27 lying behind.
- the trimming knife 9 shown in detail in FIG. 3 is used.
- the Kappmesser 9 has a disc-shaped knife body 10, whose outline or envelope is circular or cylindrical. With the circular or cylindrical axis of the knife body 10 coincides a drive axle or shaft 12, via which the entire rotary blade 9 is rotationally driven. At two diametrically opposite points, the knife body 10 has sector-like recesses 23, each having a flank 25 is radially or radius parallel to the drive axis 12. This flank 25 serves to bear knife blades 11, which protrude with a free end radially outwardly beyond the blade body 10, wherein a knife edge 13 is located at this end.
- the knife body 10 is driven in the direction of arrow B.
- the knife body rolls 10 quasi on the running past him, coated with the edge material 4 narrow side surface 3 of the workpieces 1 and is in this case controlled so that the relevant knife edge 13 comes into engagement with the edge material 4 at the intended interface.
- the knife edge 13 is carried along by rotation of the knife body 10 with the passage of the edge strip 4 to be cut and dips into the material of the edge strip 4 or through this material, to be then rotated out of the engagement position with the interface. It is understood that the length of the knife edges 13 seen in the height direction must be equal to or greater than the width of the edge material 4.
- the radial projection of the knife edges 13 beyond the blade body 10 is also sufficiently large to preclude a collision between the workpieces 1 or the edge material 4 and the knife body 10 applied thereto.
- the knife body 10, on which the coated narrow sides of the workpiece pass tangentially or tangentially parallel, have a small distance from these narrow sides of the workpiece.
- FIG. 3 also illustrates this, in addition to the representation of FIG. 4.
- the cutting edges 13 on the two blades 11 are ground obliquely over the blade thickness.
- there each blade 13 is in the plane of a flat flank or outside 24 of each blade 11.
- the one blade 11 is applied with this flat edge 24 to the edge 25 of the recess 23 of the blade body 10, the second blade 11 according to their level Flank 24 opposite side.
- the rotation of the knife body 10 is now controlled so that the flat sides 24 of the blades 11, which terminate in the cutting edges 13, on the one hand to the accrding, in the direction of passage of the workpieces 1 forward workpiece narrow side 26 and the other to the in the direction of passage of the workpieces. 1 rearward, running down narrow side of the workpiece 27 are arranged. This results in optimum cutting conditions at the two ends of the respective edge strip 4 to be cut, and a sufficient chip space is also available through the cutouts 23 on the knife body 10.
- Fig. 5 makes as well as Fig. 4 clearly that seen in the direction of passage of the workpieces 1 in succession, two or more rotary blades 9 can be arranged one behind the other.
- separating or incisions by means of the rotary blade 9 in the course of the narrow surface side 3, to which the edge material 4 is applied can be performed.
- the edge material 4 is one which is provided with a sealing bead 4a, as FIG. 5a makes clear.
- Fig. 6 shows another possible use of the rotary blade 9, which is provided when a plurality of workpieces 1 have been coated in a tight sequence by means of the Kantenanleimaggregates the edgebander at the mutually aligned workpiece narrow side surfaces together with a strip of edge material 4. The then still contiguous workpieces 1 can be separated from each other at the existing gaps between them J by means of the rotary blade 9 of the strip of edge material 4 is severed.
- FIGS. 7 and 8 show a special arrangement for the rotary knife 9. This design is provided, in particular, when the edge material 4 applied to the workpieces 1 is not severed but merely cut or cut away from it. This is about pressing the rotary blade 9 resiliently against the edge material 4 on the relevant narrow side surfaces of the workpieces 1.
- Figures 7 and 8 illustrate basic features for the drive of the rotary blade 9.
- the rotary blade 9 is connected via a shaft 12, which represents the axis of rotation, with a positioning drive 15, which is controlled so that the relevant blade cutting the intended interface on Band 4 follows.
- Another element of the control system for the rotary knife 9 is a sensor 14 which scans reference points or marks on the continuous workpieces 1. It can be here to the transverse to the conveying direction the workpieces 1 lying workpiece narrow sides 26 or 27 (Fig. 2) act.
- a control command is given to the positioning drive 15 over a distance K, which then rotates the rotary blade 9 in such a way that the relevant blade edge comes into matching engagement with the edge material 4 or with the sealing bead 4a attached thereto. If two knife edges 13 are present on the rotary knife 9, as illustrated in FIG. 3, then the rotary knife 9 makes a rotation of 180 ° for one cutting operation on one of the two narrow plate sides 26, 27.
- FIGS. 7 and 8 show those features that cause a resilient application of the rotary blade 9 to the continuous workpieces 1.
- the rotary knife is arranged with its positioning drive 15 on a carriage 18 which is movable on guide rods 17 transversely to the direction of passage of the workpieces 1.
- the guide rods 17 are fastened by means of a holder 16 to the machine frame 29 shown schematically in FIGS. 7 and 8.
- the carriage 18 is acted upon by a pneumatic cylinder 19, and the support of the carriage 18 including the rotary blade 9 on the continuous narrow side surface of the respective workpieces 1 and on the edge material 4 mounted thereon via a Tastrad 20, which is arranged on a on the carriage 18 Support arm 28 is mounted.
- an adjusting screw 21 with a corresponding adjusting spindle, via which the axis of the feeler wheel 20th relative to the axis of the rotary blade 9 can be adjusted transversely to the direction of passage of the workpieces 1.
- a top pressure 30 is shown, which runs along with the workpieces 1 and this presses against the conveyor chain 2.
- Fig. 9 shows an arrangement of two rotary blades 9, as it is preferably provided when the workpieces 1 in the direction of passage A a tight sequence with a narrow distance J have.
- the two rotary blades 9 are each arranged on a carriage 18, but which has two retaining arms 31 projecting in the direction of the continuous workpieces 1 and each carrying a jockey wheel 22 and a follower roller , These retaining arms 31 engage around the respective rotary blade laterally, so that viewed in the direction of passage of the workpieces 1, the rotary blades 9 and the contact wheels 22 have an axial spacing.
- the rotary blades 9 so to speak protrude through the keying.

Abstract
Description
Die Erfindung bezieht sich auf eine Maschine oder eine Maschinenstation zum Anbringen eines streifen- oder bandförmigen Kantenmaterials und zum Schneiden dieses Kantenmaterials an plattenförmigen Werkstücken der im Gattungsbegriff des Patentanspruchs 1 näher bezeichneten Art (siehe EP 0 578 199 A).The invention relates to a machine or a machine station for applying a strip or strip-shaped edge material and for cutting this edge material to plate-shaped workpieces of the type specified in the preamble of
Bei Maschinen oder Maschinenstationen der vorgenannten Art werden die Trennaggregate zum Kappen des auf die Schmalseitenflächen der Werkstücke aufgebrachten Kantenmaterials eingesetzt. Eine Kantenanleimmaschine, mit der das Kantenmaterial an die Schmalseitenflächen der Werkstücke im Durchlauf angefahren werden kann, zeigt die Patentschrift DE 42 17 291 C1. Das aufgebrachte Kantenmaterial wird üblicherweise nicht nur an seinen Längsseiten sondern auch in Durchlaufrichtung der Werkstücke gesehen sowohl am vorderen Ende der betreffenden Werkstückschmalseitenfläche als auch an deren rückwärtigen Ende mit Überstand aufgebracht, und auch diese Überstände müssen in der Regel bündig mit den in Durchlaufrichtung vorn- und hintenliegenden Werkstückschmalseiten abgekappt werden.In machines or machine stations of the aforementioned type, the separation units are used for capping the edge material applied to the narrow side surfaces of the workpieces. An edge banding machine, with which the edge material can be approached on the narrow side surfaces of the workpieces in the run, shows the patent DE 42 17 291 C1. The applied edge material is usually applied not only on its longitudinal sides but also in the direction of passage of the workpieces seen both at the front end of the relevant workpiece narrow side surface and at the rear end with protrusion, and these supernatants must be flush with the forward and forward in the rule Be capped behind the workpiece narrow sides.
Eine Durchlaufmaschine mit hierzu geeigneten Kappaggregaten ist aus der Offenlegungsschrift EP 0 578 199 A1 bekannt.A continuous machine with suitable cutting units is known from the published patent application EP 0 578 199 A1.
Bei den Kappaggregaten handelt es sich um Kappsägen mit rotierenden Kreissägeblättern, die nicht nur quer zur Durchlaufrichtung der Werkstücke zugestellt, sondern während des Kappvorgangs entlang eines Wegstücks in Durchlaufrichtung synchron mit den Werkstücken mitbewegt werden.The trimming units are chop saws with rotating circular saw blades, which are not only delivered transversely to the passage direction of the workpieces, but are moved along during the copying process along a path in the direction of passage synchronously with the workpieces.
An derartigen Durchlaufmaschinen oder entsprechenden Maschinenstationen ist aus den geschilderten Gründen ein Aufbauplatz für die Kappaggregate erforderlich, der eine erhebliche Länge in Werkstückdurchlaufrichtung erfordert. Bei gängigen Maschinen muß dafür eine Länge von etwa 1.800 mm vorgesehen werden, was einen merklichen Teil der Gesamtlänge einer im Durchlauf arbeitenden Kantenanleimmaschine oder -station ausmacht.At such pass machines or corresponding machine stations, a mounting location for the trimming units is required for the described reasons, which requires a considerable length in the workpiece passage direction. For common machines, a length of about 1,800 mm must be provided for this, which makes up a considerable part of the total length of a continuous edgebander or station.
Der Erfindung liegt die Aufgabe zugrunde, eine Maschine oder eine Maschinenstation der eingangs genannten Art zu schaffen, bei der für das zumindest eine Trennaggregat zum Kappen des auf die Werkstückschmalseiten aufgebrachten Kantenmaterials ein Aufbauplatz von geringer Länge in Werkstückdurchlaufrichtung benötigt wird, wobei das Trennaggregat des weiteren für universelle Ein- oder Durchschnitte am Kantenmaterial einsetzbar ist.The invention has for its object to provide a machine or a machine station of the type mentioned, in which for the at least one separation unit for capping the applied on the narrow sides of the workpiece edge material a construction space of short length in the workpiece passage direction is needed, the separation unit of the other for universal inputs or averages can be used on the edge material.
Diese Aufgabe wird bei einer Maschine oder einer Maschinenstation der gattungsbildenden Art nach der Erfindung durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved in a machine or a machine station of the generic type according to the invention by the features of
Für die Erfindung ist wesentlich, daß das neue Rotationsmesser ortsfest angeordnet ist und deshalb hierfür ein Verfahrweg in Werkstückdurchlaufrichtung nicht vorgesehen werden muß. Gegenüber den Kappaggregaten mit vergleichbarerFor the invention it is essential that the new rotary knife is arranged stationarily and therefore for this purpose a travel path in the workpiece passage direction need not be provided. Compared to the trimming units with comparable
Funktion reduziert sich die Länge des Aufbauplatzes für das ortsfeste Rotationsmesser auf das 0,15- bis 0,1 fache. Das Schneiden des Kantenmaterials mit einer ein- oder durchtauchenden Messerschneide kann wesentlich schneller als das Durchtrennen des Kantenmateri-als mittels eines zerspanenden Sägeblattes vorgenommen werden. Darüber hinaus läßt sich das Mitführen der Schneide mit der jeweiligen Schnittstelle des auf die Werkstückschmalseitenflächen aufgebrachten Kantenmaterials durch entsprechende Drehung des Messerkörpers bewerkstelligen, wobei ferner noch an der Schnittstelle der Hub der Messerschneide quer zur Werkstückdurchlaufrichtung entsprechend der Projektion des Kreisbahnbogens, auf dem die Messerschneide beim Schneiden sich bewegt, auf die Radialrichtung senkrecht zur Werkstückdurchlaufrichtung für die Schnittiefe genutzt werden kann.Function reduces the length of the mounting location for the stationary rotary knife to 0.15 to 0.1 times. The cutting of the edge material with a single or submerged knife edge can be done much faster than the cutting of the edge material than by means of a cutting saw blade. In addition, the entrainment of the cutting edge can be accomplished with the respective interface of the edge material applied to the workpiece narrow side surfaces by appropriate rotation of the knife body, further still at the interface of the stroke of the knife edge transverse to the workpiece passage direction corresponding to the projection of the circular arc on which the knife edge during cutting moves, can be used in the radial direction perpendicular to the workpiece passage direction for the depth of cut.

Im einzelnen zeigt Fig. 1 Werkstücke 1, die auf einer Transportkette 2 in Richtung des Pfeiles A befördert werden. Hierbei sind die einen Schmalseitenflächen 3 der Werkstücke 1 in der Förderrichtung in einer Flucht angeordnet, damit darauf im Vorbeilauf an einem Kantenanleimaggregat ein Kantenstreifen 4 aufgebracht werden kann. Das Kantenanleimaggregat weist eine Vorratsrolle 5 auf, von dem das Kantenmaterial 4 abgezogen und mittels Andruckrollen 6 unter Verkleben an die Schmalseitenflächen 3 der Werkstücke 1 herangeführt wird. Am Kantenanleimaggregat kann ein Kappmesser 7 vorgesehen sein, um einen Streifen vorbestimmter Länge von dem Kantenmaterial 4 abzuschneiden, der für die Beschichtung einer Schmalseitenfläche 3 der Werkstücke 1 vorgesehen ist.In detail, Fig. 1 shows
Nach dem Vorbeilaufen an dem Kantenanleimaggregat passieren die Werkstücke 1 Bündigfräsaggregate 8, welche das Kantenmaterial 4 auf der beschichteten Schmalseitenfläche 3 der Werkstücke 1 ober- und unterseitig bündig mit der Ober- und Unterseite der plattenförmigen Werkstücke 1 besäumen. Anschließend werden die Werkstücke 1 auf der Transportkette 2 im weiteren Durchlauf an einem Rotationsmesser 9 vorbeigeführt, welches am Durchlaufweg ortsfest angeordnet ist und das nachstehend noch näher beschrieben werden wird.After passing the edge banding unit, the
Mit dem Rotationsmesser 9 werden die in Durchlaufrichtung vorderen und hinteren Überstände des auf die Schmalseitenflächen 3 der Werkstücke 1 aufgetragenen Kantenmaterials 4 gekappt. Dazu zeigt Fig. 2 jeweils den Betrag C und D, um den das Kantenmaterial 4 über die in Förderrichtung der Werkstücke 1 vorn liegenden Werkstückschmalseiten 26 und hinten liegenden Werkstückschmalseiten 27 übersteht. Zum Abtrennen dieser Überstände dient das im einzelnen in Fig. 3 dargestellte Kappmesser 9.With the
Das Kappmesser 9 hat einen scheibenförmigen Messerkörper 10, dessen Umriß oder Umhüllende kreisförmig bzw. zylinderförmig ist. Mit der Kreis- bzw. Zylinderachse des Messerkörpers 10 fällt eine Antriebsachse oder -welle 12 zusammen, über die das gesamte Rotationsmesser 9 drehend antreibbar ist. An zwei einander diametral gegenüberliegenden Stellen weist der Messerkörper 10 sektorartige Aussparungen 23 auf, deren jeweils eine Flanke 25 radial bzw. radiusparallel zur Antriebsachse 12 liegt. Diese Flanke 25 dient zur Anlage von Messerklingen 11, die mit einem freien Ende radial nach außen über den Messerkörper 10 vorstehen, wobei sich an diesem Ende eine Messerschneide 13 befindet.The
Der Messerkörper 10 wird in Richtung des Pfeiles B angetrieben. Während des Schneidvorgangs wälzt sich der Messerkörper 10 quasi an der an ihm vorbeilaufenden, mit dem Kantenmaterial 4 beschichteten Schmalseitenfläche 3 der Werkstücke 1 ab und wird hierbei so gesteuert, daß die betreffende Messerschneide 13 an der vorgesehenen Schnittstelle in Eingriff mit dem Kantenmaterial 4 kommt. Dabei wird die Messerschneide 13 durch Drehung des Messerkörpers 10 mit dem Durchlauf des zu schneidenden Kantenstreifens 4 mitgeführt und taucht in das Material des Kantenstreifens 4 ein bzw. durch dieses Material hindurch, um danach aus der Eingriffslage mit der Schnittstelle herausgedreht zu werden. Es versteht sich, daß die Länge der Messerschneiden 13 in Höhenrichtung gesehen gleich groß oder größer als die Breite des Kantenmaterials 4 sein muß. Außerdem ist der radiale Überstand der Messerschneiden 13 über den Messerkörper 10 hinaus ausreichend groß, um eine Kollision zwischen den Werkstücken 1 bzw. dem darauf aufgebrachten Kantenmaterial 4 und dem Messerkörper 10 auszuschließen. So kann der Messerkörper 10, an dem die beschichteten Werkstückschmalseiten tangential oder tangentenparallel vorbeilaufen einen geringen Abstand von diesen Werkstückschmalseiten haben.The
Wie aus Fig. 4 hervorgeht, muß für den Schnitt des Kantenmaterials 4 bündig mit der in Durchlaufrichtung vornliegenden Werkstückschmalseite 26 eine andere Anordnung der Messerschneide 13 am Rotationsmesser 9 vorgesehen werden als für den Schnitt bündig mit der in Durchlaufrichtung der Werkstücke 1 rückwärts liegenden Werkstückschmalseite 27. Auch das veranschaulicht Fig. 3, ergänzend zu der Darstellung von Fig. 4. Die Schneiden 13 an den beiden Klingen 11 sind über die Klingendicke hinweg schräg geschliffen. Dabei befindet sich jeweils die Schneide 13 in der Ebene einer ebenen Flanke oder Außenseite 24 jeder Klinge 11. Die eine Klinge 11 ist mit dieser ebenen Flanke 24 an die Flanke 25 der Aussparung 23 des Messerkörpers 10 angelegt, die zweite Klinge 11 entsprechend mit ihrer der ebenen Flanke 24 gegenüberliegenden Seite. Die Rotation des Messerkörpers 10 wird nun so gesteuert, daß die ebenen Seiten 24 der Klingen 11, welche in die Schneiden 13 auslaufen, zum einen zu der auflaufenden, in Durchlaufrichtung der Werkstücke 1 vornliegenden Werkstückschmalseite 26 und zum anderen zu der in Durchlaufrichtung der Werkstücke 1 rückwärtigen, ablaufenden Werkstückschmalseite 27 hin angeordnet sind. Dadurch ergeben sich optimale Schnittbedingungen an den beiden zu kappenden Enden des jeweiligen Kantenstreifens 4, außerdem steht durch die Aussparungen 23 am Messerkörper 10 ein genügender Spanraum zur Verfügung.As is apparent from Fig. 4, a different arrangement of the
Fig. 5 macht ebenso wie Fig. 4 deutlich, daß grundsätzlich in Durchlaufrichtung der Werkstücke 1 gesehen hintereinander auch zwei oder mehrere Rotationsmesser 9 angeordnet sein können. Weiter geht aus Fig. 5 hervor, daß Trenn- oder Einschnitte mittels des Rotationsmessers 9 auch im Verlauf der Schmalflächenseite 3, auf die das Kantenmaterial 4 aufgebracht ist, ausgeführt werden können. Dies ist beispielsweise der Fall, wenn es sich bei dem Kantenmaterial 4 um ein solches handelt, welches mit einem Dichtwulst 4a versehen ist, wie Fig. 5a deutlich macht. Hierbei kann es erforderlich sein, den Dichtwulst 4a nur über eine Länge G sich erstrecken zu lassen und zu oder zwischen den weiteren Abschnitten des Dichtwulstes 4a Lücken F und H zu lassen.Fig. 5 makes as well as Fig. 4 clearly that seen in the direction of passage of the
Fig. 6 zeigt eine andere Verwendungsmöglichkeit des Rotationsmessers 9, die dann vorgesehen wird, wenn eine Mehrzahl von Werkstücken 1 in einer dichten Folge mittels des Kantenanleimaggregates der Kantenanleimmaschine an den miteinander fluchtenden Werkstückschmalseitenflächen gemeinsam mit einem Streifen des Kantenmaterials 4 beschichtet worden sind. Die dann zunächst noch zusammenhängenden Werkstücke 1 können an den zwischen diesen bestehenden Lücken J voneinander getrennt werden, indem mittels des Rotationsmessers 9 der Streifen des Kantenmaterials 4 durchtrennt wird.Fig. 6 shows another possible use of the
Die Figuren 7 und 8 zeigen eine besondere Anordnung für das Rotationsmesser 9. Diese Bauform wird insbesondere dann vorgesehen, wenn das auf die Werkstücke 1 aufgetragene Kantenmaterial 4 nicht durchtrennt sondern lediglich angeschnitten oder davon etwas abgeschnitten werden soll. Hierbei geht es darum, das Rotationsmesser 9 federnd gegen das Kantenmaterial 4 an den betreffenden Schmalseitenflächen der Werkstücke 1 anzudrücken.FIGS. 7 and 8 show a special arrangement for the
Zunächst veranschaulichen die Figuren 7 und 8 grundsätzliche Merkmale für den Antrieb des Rotationsmessers 9. Dazu ist das Rotationsmesser 9 über eine Welle 12, welche die Rotationsachse darstellt, mit einem Positionierantrieb 15 verbunden, der so angesteuert wird, daß die betreffende Messerschneide der vorgesehenen Schnittstelle am Bandmaterial 4 nachfolgt. Weiteres Element des Steuerungssystems für das Rotationsmesser 9 ist ein Sensor 14, der Referenzstellen oder -marken an den durchlaufenden Werkstücken 1 abtastet. Es kann sich hierbei um die quer zur Förderrichtung der Werkstücke 1 liegenden Werkstückschmalseiten 26 oder 27 (Fig. 2) handeln. Spricht der Sensor 14 an, wird über eine Wegstrecke K ein Steuerbefehl an den Positionierantrieb 15 gegeben, der daraufhin das Rotationsmesser 9 so dreht, daß die betreffende Messerschneide in passenden Eingriff mit dem Kantenmaterial 4 bzw. mit dem daran angebrachten Dichtwulst 4a kommt. Sind zwei Messerschneiden 13 an dem Rotationsmesser 9 vorhanden, wie es Fig. 3 veranschaulicht, dann führt das Rotationsmesser 9 für einen Schneidvorgang an einer der beiden Plattenschmalseiten 26, 27 eine Drehung von 180° aus.First, Figures 7 and 8 illustrate basic features for the drive of the
Weiter gehen aus den Figuren 7 und 8 diejenigen Merkmale hervor, die eine federnde Beaufschlagung des Rotationsmessers 9 hin zu den durchlaufenden Werkstücken 1 bewirken. Dazu ist das Rotationsmesser mit seinem Positionierantrieb 15 an einem Schlitten 18 angeordnet, der auf Führungsstangen 17 quer zur Durchlaufrichtung der Werkstücke 1 verfahrbar ist. Die Führungsstangen 17 sind mittels einer Halterung 16 an dem in den Figuren 7 und 8 andeutungsweise dargestellten Maschinengestell 29 befestigt. Der Schlitten 18 wird von einem Pneumatikzylinder 19 beaufschlagt, und die Abstützung des Schlittens 18 einschließlich dem Rotationsmesser 9 an der durchlaufenden Schmalseitenfläche der jeweiligen Werkstücke 1 bzw. an dem darauf angebrachten Kantenmaterial 4 erfolgt über ein Tastrad 20, welches an einem auf dem Schlitten 18 angeordneten Tragarm 28 gelagert ist. Zur Einstellung der Schnittiefe der Messerschneiden am Rotationsmesser 9 dient eine Stellschraube 21 mit entsprechender Stellspindel, über die die Achse des Tastrades 20 relativ zu der Achse des Rotationsmessers 9 quer zur Durchlaufrichtung der Werkstücke 1 verstellt werden kann.Next go from Figures 7 and 8 show those features that cause a resilient application of the
Im übrigen ist in Fig. 8 noch ein Oberdruck 30 dargestellt, welcher mit den Werkstücken 1 mitläuft und diese gegen die Transportkette 2 preßt.Incidentally, in Fig. 8, a
Fig. 9 zeigt eine Anordnung von zwei Rotationsmessern 9, wie sie vorzugsweise dann vorgesehen wird, wenn die Werkstücke 1 in der Durchlaufrichtung A eine dichte Folge mit einem engen Abstand J aufweisen. In gleicher Art wie nach dem Ausführungsbeispiel der Figuren 7 und 8 sind die beiden Rotationsmesser 9 je auf einem Schlitten 18 angeordnet, der jedoch zwei Haltearme 31 aufweist, die in Richtung zu den durchlaufenden Werkstücken 1 vorstehen und je ein Tastrad 22 bzw. eine Tastrolle tragen. Diese Haltearme 31 umgreifen das jeweilige Rotationsmesser seitlich, so daß in Durchlaufrichtung der Werkstücke 1 gesehen die Rotationsmesser 9 und die Tasträder 22 einen Achsabstand haben. Bei dieser Ausführung ragen die Rotationsmesser 9 sozusagen durch die Tastung hindurch.Fig. 9 shows an arrangement of two
