Definitions
- the invention relates to a device for processing side edges of sheet-shaped substrates, according to the preamble of claim 1, in particular for preparing a perfect binding.
- the sheet-like substrates that make up the finished book or booklet at the end are first collected and aligned in a stack. This stack of sheet-shaped substrates is clamped so that slipping of the individual sheet-shaped substrates in the stack is possible excluded. Subsequently, one side of the stack of sheet-like substrates is first milled flat and then coated with a suitable adhesive. Suitable adhesives are various hot glues or cold glues, so-called dispersion glues in question. However, the type of adhesive is irrelevant to the present invention.
- the adhesive usually has only a small contact surface with the sheet-shaped substrate to be fixed, since the adhesive can connect only with a straight side edge of the individual sheet-shaped substrates , This leads to a low pull-out strength of the sheet-like substrates in the finished product.
- the quality of the perfect binding can be improved by increasing the surface of the side edge and thus the contact surface between the adhesive and the sheet-shaped printing material.
- a further improvement of the adhesive bond can be achieved by the wetting of the side edge of the sheet-shaped substrate is improved by adhesive.
- This can be done, for example, by exposing the paper fibers to the side edge of the sheet-like substrate, which ultimately provides for the mechanical anchoring of the sheet-like substrate in the adhesive.
- This is an important requirement, in particular for coated papers, since even with these only the fiber content contributes to the strength, but the proportion of the coating can make up to half of the material here. Therefore, in many devices for processing side edges of sheet-like substrates in preparation for perfect binding, an additional scoring tool or other roughening tool is used to expose the paper fiber and improve anchoring between paper and adhesive.
- Such a device is described for example in the Swiss patent CH 30 36 78 disclosed.
- a first outer ring cutting tools for equalizing a book spine are mounted in an inner ring notching tools are provided for roughening the spine.
- a passing book block is thereby first leveled by the cutting tools and then provided by the notching tools with arcuate, mutually crossing notches on the back.
- a cutter disk rotates on a drive shaft, the cutter disk carrying cutting teeth along its circumference to trim the back edge of a stack of paper passed over it. Further, one or more upwardly directed cutting teeth are mounted on the cutter disk so that they can be positioned vertically. As a result, the cutting depth of the upwardly directed cutting teeth can be changed.
- a rotary driven tool head is provided with circumferentially distributed external tools for machining the block spine, such as milling or trimming, and with tools arranged within the external tools for reworking the block spine, such as notches and roughening.
- the device provides a stepwise height adjustment between the first tools and the second tools to change the cutting depth of the second tools.
- brushes are also provided on the tool head, which eliminate the dust produced during the processing of the book block spine and resulting loose paper particles.
- the device is an apparatus for processing along a direction moving side edges of arranged in a stack of sheet-shaped substrates in a sectional plane, which has a rotationally driven tool head with a fixed axis of rotation, wherein on the tool head substantially circular notch elements for the roughening of the side edges of the sheet-like printing materials are arranged and arranged around the substantially circular notch elements cutting elements for edging sheet-shaped substrates, the axis of rotation relative to the vertical on the cutting plane forms an acute angle ⁇ , so that the cutting elements only on one side of the Tool head come into contact with the side edges of the sheet-shaped substrates.
- the side of the tool head is, in particular, the side leading in the direction of movement.
- the cutting elements By virtue of the fact that the cutting elements only come into contact with the side edges of the sheet-like printing substrates on one side, the cutting forces occurring during machining can be reduced, which leads to a higher power of the cutting tool. By reducing the cutting forces fanning the stack of sheet-like substrates during processing can be prevented.
- the angle ⁇ is set such that the notch elements dip twice in the cutting plane of the sheet-like substrates, the cutting elements, however, only once.
- the notch elements in two different Aufrautiefen score the side edges of the sheet-shaped substrates The fact that the notch elements indent the second immersion in a lower roughening the side edges, it comes to lower cutting forces.
- the stack of sheet-like printing materials is slightly fanned out in this area, the lower cutting forces lead to an advantageous dedusting of the cutting plane. Thorough dedusting of the machined side edge of the sheet substrates is important as the paper and dust particles otherwise present on the working surface will adversely affect the wetting of the side edges by adhesives.
- Another advantage results from the inclination of the axis of rotation, which unavoidable manufacturing and assembly tolerances, which lead to a tumbling motion of the tool head, can be compensated by a sufficiently large choice of the angle ⁇ .
- the arrangement of notch elements and cutting elements on the same tool head can be very favorably influenced on the roughening depth of the notch elements.
- the roughness which indicates the penetration of the notch elements above the cutting plane, is an essential factor that goes into the properties of a finished perfect binding.
- a low roughening depth means that the adhesive applied to the processed side edges of the sheet-like printing materials arranged in the stack can penetrate only slightly laterally into the stack of sheet-shaped printing substrates.
- a low penetration depth of the adhesive is typically associated with a low pull-out strength of the sheet-form substrates from the stack, but an advantageous impact behavior of the bound stack of sheet-like substrates.
- the notch depth of the notch elements is infinitely adjustable. This is particularly advantageous to adapt the processing of the side edges of the sheet-shaped substrates to the properties of the stack, z. B. number of sheet-shaped substrates in the stack, type of sheet-shaped substrates, whether and how the sheet-like substrates are printed, especially in the area of the side edge to be processed etc.
- the stepless adjustability of the notch depth can be achieved, for example, by a stepless adjustability of the angle ⁇ .
- the notch elements can be arranged on a Kerbring, which is height adjustable by means of a left-hand thread and with a corresponding device for fixing in a desired position with respect to the cutting edge and the cutting plane of the cutting elements.
- the notch elements are arranged on a notch ring and the cutting elements are arranged on a cutting ring, Kerbring and cutting ring are separately releasably secured to the tool head.
- the final assembly of the tool head can be facilitated and the entirety of the cutting elements can be easily replaced.
- the cutting elements are all first fastened to the cutting ring, in order then to be ground together into their final shape. This type makes it possible to bring the cutting edges of all the individual cutting elements on the cutting ring with very small tolerances in the same cutting plane. The same applies to the production of a Kerbringes and the corresponding notch elements.
- notch elements on the cutting ring between the individual cutting elements or at least some cutting elements is also within the scope of the device according to the invention.
- a larger radius of the circular arrangement of the notch elements can be achieved by the displacement of the notch elements between the cutting elements, so that a larger number of notch elements can find space on the tool head.
- the speed with which the notch elements in the milled side of the stack of sheet-shaped substrates increased by the larger radius, which leads to an improvement in the load of the notch elements would be in addition.
- At least one notch element is mounted on the side facing away from the sheet-shaped substrates of the Kerbringes. This is particularly advantageous if the installation of the turned Kerbringes in the tool head can achieve a second preferred notch depth. In this way, an adaptation of the roughness depth between two preferred roughness depths can be achieved in a simple manner.
- a setting of the roughening depth by placing the Kerbringes underlay. It is, depending on the desired roughness, a suitable washer between Kerbring and Tool head inserted.
- This underlay can optionally be used in addition to a stepless height adjustment, in combination with a stepless height adjustment or instead of a stepless height adjustment of the roughening depth of the notch elements. It is also within the scope of the invention that the desired Aufrautiefe is achieved by combining a plurality of washers between Kerbring and tool head. It will be apparent to those skilled in the art that other suitable underlaying means may be used instead of washers.
- the cutting elements are soldered to the cutting ring, in particular before the cutting elements are ground to their final shape.
- a cleaning brush is integrated on the tool head.
- the cleaning brush is mounted on the surface of the tool head in the area that lies within the arrangement of the cutting elements, and serves to improve the dedusting of the machined surface of the stack of sheet-like substrates.
- a negative pressure in the region of the tool head is specifically generated by the rotation of the tool head, which sucks the dust and paper particles formed during processing.
- This can be achieved, for example, by providing a fan spiral in the center of the milling disk, which generates a flow of air away from the machined surface of the stack of sheet-like substrates, comparable to the operating principle of a hair dryer.
- an advantageous extraction can be achieved directly at the point of origin of the dust and paper particles, which in turn promotes the dedusting and thus the improvement the wetting of the side edges of the sheet-like substrates by the adhesive improves the quality of the perfect binding.
- the tool head 20 consists of a tool carrier 21, on the surface of a cutting ring 30 and a Kerbring 40 are attached.
- the tool head 20 is connected to a shaft 10 (see FIG. FIG. 4 ) appropriate.

- the cutting elements 32 are in the direction of rotation 14 forward inclined to the cutting ring 30 attached.
- the cutting elements 32 have cutting segments 34 which cause the section through the sheet-like substrates 1.
- the cutting segments are the outer edges of the cutting elements 32 leading in the direction of movement 14.
- the cut through the sheet-shaped printing stock essentially takes place at the cutting corner 37, which represents the upper end of the cutting segments 34.
- the cutting segment 34 has a typical undercut.

- the notch elements 36 may likewise be diamond-ground carbide flakes or ground steel flakes which have been subsequently hardened, for. B. by ion implantation.
- the notch elements 36 likewise have an upper corner 39, which decisively determines the roughening depth of the device according to the invention.
- the roughening depth of the notch elements 36 or the upper corner 39 of the notch elements 36 results from the height offset between the upper corner 39 of the notch elements 36 and the upper corner 37 of the cutting segments 34.
- the cutting elements and the notching elements are arranged substantially on a circle. This is not necessarily so.
- the notch elements 36 may be offset in the radial direction to achieve alternative notching patterns in the milled side of the stack of sheet-like substrates 1. It is also conceivable, two or more Kerbringe 40 on provide the tool head 20, which also have, for example, only a smaller number of notch elements 36 per Kerbring 40.
- the cutting ring 30 and the Kerbring 40 with individual drives and cutting ring 30 and Kerbring 40 rotate at a relative speed to each other, in particular in opposite directions.
- the opposite rotation of Kerbring 30 and cutting ring 40 can be improved by the counter forces occurring trimming or notching.
- the fanning stack of sheet-shaped substrates 1 is reduced by the opposing forces.
- this height offset between the upper corner 39 of the notch elements 36 and the upper corner 37 of the cutting segments 34 can be influenced by shims 60 between the Kerbring 40 and the tool carrier 21 are inserted. Since in the illustrated embodiment of the device according to the invention, as in FIG. 2 it can be seen that the Kerbring 40 lies on the cutting ring 30, which in turn rests on the support 21, the washers 60 between the Kerbring 40 and the tool carrier 21 between the Kerbring 40 and the cutting ring 30 are underlaid to change the Aufrautiefe to reach.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Bearbeitung von Seitenkanten von blattförmigen Bedruckstoffen, gemäß des Oberbegriffs des Anspruchs 1, insbesondere zur Vorbereitung einer Klebebindung.The invention relates to a device for processing side edges of sheet-shaped substrates, according to the preamble of
Für Bücher oder Broschüren in kleinen Auflagen wird häufig zum Verbindung der einzelnen Blätter eine Klebebindung verwendet. Besonders werden Klebebindung für die Weiterverarbeitung von Digitaldrucken und Kopien eingesetzt, da hierbei besonders niedrige Auflagen, z.B. von nur einem Exemplar hergestellt werden.For books or brochures in short runs, an adhesive binding is often used to connect the individual sheets. In particular, perfect binding is used for the further processing of digital prints and copies, since particularly low runs, e.g. made from just one copy.
Zur Herstellung einer Klebebindung werden die blattförmigen Bedruckstoffe, die am Ende das fertig gebundene Buch oder die Broschüre ausmachen, zunächst gesammelt und in einem Stapel zueinander ausgerichtet. Dieser Stapel blattförmiger Bedruckstoffe wird derart geklemmt, so dass ein Verrutschen der einzelnen blattförmigen Bedruckstoffe im Stapel möglichst ausgeschlossen ist. Im Anschluss wird eine Seite des Stapels blattförmiger Bedruckstoffe zunächst plangefräst und dann mit einem geeigneten Klebemittel bestrichen. Als Klebemittel kommen verschiedene Heißleime oder Kaltleime, sogenannte Dispersionsleime in Frage. Die Art des Klebemittels ist für die vorliegende Erfindung allerdings unerheblich. Werden die Seitenkanten der blattförmigen Bedruckstoffe lediglich abgefräst bevor das Klebemittel aufgetragen wird, so hat das Klebemittel in der Regel nur eine geringe Kontaktfläche mit dem blattförmigen Bedruckstoff, der fixiert werden soll, da das Klebemittel sich nur mit einer geraden Seitenkante der einzelnen blattförmigen Bedruckstoffe verbinden kann. Dies führt zu einer niedrigen Ausreißfestigkeit der blattförmigen Bedruckstoffe im fertig gebundenen Produkt.To produce an adhesive binding, the sheet-like substrates that make up the finished book or booklet at the end are first collected and aligned in a stack. This stack of sheet-shaped substrates is clamped so that slipping of the individual sheet-shaped substrates in the stack is possible excluded. Subsequently, one side of the stack of sheet-like substrates is first milled flat and then coated with a suitable adhesive. Suitable adhesives are various hot glues or cold glues, so-called dispersion glues in question. However, the type of adhesive is irrelevant to the present invention. If the side edges of the sheet-like substrates are only milled before the adhesive is applied, the adhesive usually has only a small contact surface with the sheet-shaped substrate to be fixed, since the adhesive can connect only with a straight side edge of the individual sheet-shaped substrates , This leads to a low pull-out strength of the sheet-like substrates in the finished product.
Die Qualität der Klebebindung kann verbessert werden, indem die Oberfläche der Seitenkante und damit die Kontaktfläche zwischen Klebemittel und blattförmigem Bedruckstoff vergrößert wird.The quality of the perfect binding can be improved by increasing the surface of the side edge and thus the contact surface between the adhesive and the sheet-shaped printing material.
Eine weitere Verbesserung der Klebebindung kann dadurch erzielt werden, indem die Benetzung der Seitenkante des blattförmigen Bedruckstoffs durch Klebstoff verbessert wird. Dies kann zum Beispiel dadurch erfolgen, indem die Papierfasern der Seitenkante des blattförmigen Bedruckstoffs freigelegt wird, die letztlich für die mechanische Verankerung des blattförmigen Bedruckstoffs in dem Klebemittel sorgen. Insbesondere bei gestrichenen Papieren ist dies eine wichtige Anforderung, da auch bei diesen nur der Faseranteil zur Festigkeit beiträgt, der Strichanteil aber hier bis zur Hälfte des Materials ausmachen kann. Daher wird in vielen Vorrichtungen zur Bearbeitung von Seitenkanten von blattförmigen Bedruckstoffen in Vorbereitung einer Klebebindung ein zusätzliches Kerbwerkzeug oder anderes Aufrauwerkzeug verwendet, um die Papierfaser freizulegen und die Verankerung zwischen Papier und Klebemittel zu verbessern. Neben der Aufrauung der Seitenkanten der blattförmigen Bedruckstoffe im Stapel ist es aber zusätzlich notwendig, die zu verklebende Fläche zunächst zu egalisieren, was typischerweise mit einem Fräswerkzeug in einem ersten Schritt erreicht wird. Zwingend ist der Schritt des Abfräsens der zu verklebenden Seite des Stapels bei der Klebebindung von Signaturen, da hier zunächst die Rückenfalze abzuschneiden sind.A further improvement of the adhesive bond can be achieved by the wetting of the side edge of the sheet-shaped substrate is improved by adhesive. This can be done, for example, by exposing the paper fibers to the side edge of the sheet-like substrate, which ultimately provides for the mechanical anchoring of the sheet-like substrate in the adhesive. This is an important requirement, in particular for coated papers, since even with these only the fiber content contributes to the strength, but the proportion of the coating can make up to half of the material here. Therefore, in many devices for processing side edges of sheet-like substrates in preparation for perfect binding, an additional scoring tool or other roughening tool is used to expose the paper fiber and improve anchoring between paper and adhesive. In addition to the roughening of the side edges of the sheet-like substrates in the stack, it is also necessary to first equalize the surface to be bonded, which is typically achieved with a milling tool in a first step. Mandatory is the step of milling the to be bonded side of the stack in the perfect binding of signatures, since here are the first Rückenfalze cut off.

Wie aus dem angeführten Stand der Technik zu erkennen ist, besteht Bedarf an Vorrichtungen zur Bearbeitung von Seitenkanten von blattförmigen Bedruckstoffen, insbesondere zur Vorbereitung einer Klebebindung und insbesondere an Vorrichtungen, die das Egalisieren und Aufrauen der Seitenkanten in einem einzigen Werkzeugkopf vereinen. Es ist daher die Aufgabe der vorliegenden Erfindung, eine verbesserte Vorrichtung zur Bearbeitung von Seitenkanten von blattförmigen Bedruckstoffen zu schaffen.As can be seen from the cited prior art, there is a need for devices for processing side edges of sheet-like substrates, in particular for preparing an adhesive bond, and in particular to devices that unify the leveling and roughening of the side edges in a single tool head. It is therefore the object of the present invention to provide an improved device for processing side edges of sheet-shaped substrates.
Diese Aufgabe wird mit Hilfe der erfindungsgemäßen Vorrichtung mit den in Anspruch 1 genannten Merkmalen gelöst. Weitere Merkmale ergeben sich aus den Zeichnungen und den Unteransprüchen.This object is achieved by means of the device according to the invention with the features mentioned in
Demgemäß handelt es sich bei der erfindungsgemäßen Vorrichtung um eine Vorrichtung zum Bearbeiten von entlang einer Bewegungsrichtung bewegten Seitenkanten von in einem Stapel angeordneten blattförmigen Bedruckstoffen in einer Schnittebene, wobei diese einen rotationsangetriebenen Werkzeugkopf mit einer festen Drehachse aufweist, wobei auf dem Werkzeugkopf im Wesentlichen kreisförmig Kerbelemente für das Aufrauen der Seitenkanten der blattförmigen Bedruckstoffe angeordnet sind und um die im Wesentlichen kreisförmig angeordneten Kerbelemente Schneidelemente für den Kantenbeschnitt blattförmiger Bedruckstoffe angeordnet sind, wobei die Drehachse relativ zur Senkrechten auf der Schnittebene einen spitzen Winkel α bildet, so dass die Schneidelemente nur auf einer Seite des Werkzeugkopfes in Kontakt mit den Seitenkanten der blattförmigen Bedruckstoffe gelangen. Dabei handelt es sich bei der Seite des Werkzeugkopfes insbesondere um die in Bewegungsrichtung vorauseilende Seite.Accordingly, the device according to the invention is an apparatus for processing along a direction moving side edges of arranged in a stack of sheet-shaped substrates in a sectional plane, which has a rotationally driven tool head with a fixed axis of rotation, wherein on the tool head substantially circular notch elements for the roughening of the side edges of the sheet-like printing materials are arranged and arranged around the substantially circular notch elements cutting elements for edging sheet-shaped substrates, the axis of rotation relative to the vertical on the cutting plane forms an acute angle α, so that the cutting elements only on one side of the Tool head come into contact with the side edges of the sheet-shaped substrates. In this case, the side of the tool head is, in particular, the side leading in the direction of movement.
Dadurch, dass die Schneidelemente nur auf einer Seite in Kontakt mit den Seitenkanten der blattförmigen Bedruckstoffe gelangen, können die bei der Bearbeitung auftretenden Schnittkräfte reduziert werden, was zu einer höheren Leistung des Schneidwerkzeugs führt. Durch die Reduzierung der Schnittkräfte kann ein Auffächern des Stapels blattförmiger Bedruckstoffe während der Bearbeitung verhindert werden.By virtue of the fact that the cutting elements only come into contact with the side edges of the sheet-like printing substrates on one side, the cutting forces occurring during machining can be reduced, which leads to a higher power of the cutting tool. By reducing the cutting forces fanning the stack of sheet-like substrates during processing can be prevented.
Der Winkel α ist derartig eingestellt, dass die Kerbelemente zwei Mal in die Schnittebene der blattförmigen Bedruckstoffe eintauchen, die Schneidelemente dagegen nur ein Mal. Einerseits lässt es sich dadurch erreichen, dass die Kerbelemente in zwei unterschiedlichen Aufrautiefen die Seitenkanten der blattförmigen Bedruckstoffe einkerben. Dadurch, dass die Kerbelemente beim zweiten Eintauchen in geringerer Aufrautiefe die Seitenkanten einkerben, kommt es zu geringeren Schnittkräften. Wird in diesem Bereich jedoch der Stapel blattförmiger Bedruckstoffe leicht aufgefächert, so führen die geringeren Schnittkräfte zu einer vorteilhaften Entstaubung der Schnittebene. Eine gründliche Entstaubung der bearbeiteten Seitenkante der blattförmigen Bedruckstoffe ist wichtig, da die Papier- und Staubpartikel, die sich sonst auf der bearbeitenden Oberfläche befinden, das Benetzen der Seitenkanten durch Klebemittel beeinträchtigen.The angle α is set such that the notch elements dip twice in the cutting plane of the sheet-like substrates, the cutting elements, however, only once. On the one hand, it can be achieved that the notch elements in two different Aufrautiefen score the side edges of the sheet-shaped substrates. The fact that the notch elements indent the second immersion in a lower roughening the side edges, it comes to lower cutting forces. However, if the stack of sheet-like printing materials is slightly fanned out in this area, the lower cutting forces lead to an advantageous dedusting of the cutting plane. Thorough dedusting of the machined side edge of the sheet substrates is important as the paper and dust particles otherwise present on the working surface will adversely affect the wetting of the side edges by adhesives.
Ein weiterer Vorteil ergibt sich aus der Neigung der Drehachse, womit unvermeidbare Fertigungs- und Montagetoleranzen, die zu einer Taumelbewegung des Werkzeugkopfes führen, durch ausreichend große Wahl des Winkels α kompensiert werden kann.Another advantage results from the inclination of the axis of rotation, which unavoidable manufacturing and assembly tolerances, which lead to a tumbling motion of the tool head, can be compensated by a sufficiently large choice of the angle α.
Durch die Anordnung von Kerbelementen und Schneidelementen auf dem gleichen Werkzeugkopf kann sehr günstig auf die Aufrautiefe der Kerbelemente Einfluss genommen werden. Die Aufrautiefe, die das Eindringen der Kerbelemente über der Schnittebene angibt, ist ein wesentlicher Faktor, der in die Eigenschaften einer fertigen Klebebindung eingeht. Eine geringe Aufrautiefe führt dazu, dass das auf die bearbeiteten Seitenkanten der in dem Stapel angeordneten blattförmigen Bedruckstoffe aufgetragenen Klebemittel nur gering seitlich in den Stapel blattförmiger Bedruckstoffe eindringen kann. Eine geringe Eindringtiefe des Klebemittels ist Typischerweise mit einer geringen Ausreißfestigkeit der blattförmigen Bedruckstoffe aus dem Stapel, aber einem vorteilhaften Aufschlagverhalten des gebundenen Stapels blattförmiger Bedruckstoffe verbunden. Eine große Aufrautiefe und damit ein erhöhtes Eindringen des Klebemittels in die Seite des Stapels blattförmiger Bedruckstoffe führt dagegen umgekehrt typischerweise zu einer hohen Ausreißfestigkeit der blattförmigen Bedruckstoffe aus dem Stapel, aber einem schlechten Aufschlagverhalten des gebundenen Stapels. Um sowohl ein gutes Aufschlagverhalten des gebundenen Stapels blattförmiger Bedruckstoffe und eine hohe Ausreißfestigkeit zu erreichen, ist es daher erforderlich, die Aufrautiefe möglichst optimal einzustellen. Diese optimale Aufrautiefe kann unterschiedlich sein für verschiedene Arten von blattförmigen Bedruckstoffen, je nach Qualität der blattförmigen Bedruckstoffe Papiergewicht, Material usw. Durch die Anordnung von Kerbelementen und Schneidelementen auf dem selben Werkzeugkopf kann diese vorgegebene Aufrautiefe im Zehntel Millimeterbereich durch eine einmalige Justage der Position der Kerbelemente vergleichsweise einfach vorgenommen werden. Eine Justage zweier einzelner Bearbeitungsstationen zueinander im Zehntel Millimeterbereich ist dagegen nicht notwendig.The arrangement of notch elements and cutting elements on the same tool head can be very favorably influenced on the roughening depth of the notch elements. The roughness, which indicates the penetration of the notch elements above the cutting plane, is an essential factor that goes into the properties of a finished perfect binding. A low roughening depth means that the adhesive applied to the processed side edges of the sheet-like printing materials arranged in the stack can penetrate only slightly laterally into the stack of sheet-shaped printing substrates. A low penetration depth of the adhesive is typically associated with a low pull-out strength of the sheet-form substrates from the stack, but an advantageous impact behavior of the bound stack of sheet-like substrates. Conversely, a large roughness depth and thus an increased penetration of the adhesive into the side of the stack of sheet-shaped substrates typically leads to a high pull-out strength of the sheet-shaped substrates from the stack, but a poor impact behavior of the bound stack. In order to achieve both a good impact behavior of the bound stack of sheet-like substrates and a high pull-out strength, it is therefore necessary to optimally adjust the roughness depth. This optimum Aufrautiefe may be different for different types of sheet-like substrates, depending on the quality of the sheet-like substrates paper weight, material, etc. By arranging notch elements and cutting elements on the same tool head this predetermined Aufrautiefe in tenths of a millimeter range by a single adjustment of the position of the notch elements be made comparatively easy. An adjustment of two individual Processing stations to each other in tenths of a millimeter range, however, is not necessary.
Ein weiterer Vorteil ergibt sich bei der Anordnung von Kerbelementen und Schneidelementen auf dem selben Werkzeugkopf durch den geringen erforderlichen Bauraum, wodurch kompakte Klebebinder mit vorteilhaften Leistungsdaten realisiert werden können.Another advantage arises in the arrangement of notch elements and cutting elements on the same tool head by the small space required, whereby compact perfect binder can be realized with advantageous performance data.
In einer vorteilhaften Weiterbildung der erfindungsgemäßen Vorrichtung ist die Kerbtiefe der Kerbelemente stufenlos verstellbar. Dies ist insbesondere dann von Vorteil, um die Bearbeitung der Seitenkanten der blattförmigen Bedruckstoffe an die Eigenschaften des Stapels anzupassen, z. B. Anzahl der blattförmigen Bedruckstoffe im Stapel, Art der blattförmigen Bedruckstoffe, ob und wie die blattförmigen Bedruckstoffe bedruckt sind, insbesondere im Bereich der zu bearbeitenden Seitenkante usw. Die stufenlose Verstellbarkeit der Kerbtiefe kann beispielsweise durch eine stufenlose Verstellbarkeit des Winkel α erreicht werden. Andererseits können die Kerbelemente auf einem Kerbring angeordnet sein, der mittels eines Linksgewindes und mit einer entsprechenden Vorrichtung zur Fixierung in einer gewünschten Position bezüglich der Schneidkante bzw. der Schnittebene der Schneidelemente höhenverstellbar ist.In an advantageous development of the device according to the invention, the notch depth of the notch elements is infinitely adjustable. This is particularly advantageous to adapt the processing of the side edges of the sheet-shaped substrates to the properties of the stack, z. B. number of sheet-shaped substrates in the stack, type of sheet-shaped substrates, whether and how the sheet-like substrates are printed, especially in the area of the side edge to be processed etc. The stepless adjustability of the notch depth can be achieved, for example, by a stepless adjustability of the angle α. On the other hand, the notch elements can be arranged on a Kerbring, which is height adjustable by means of a left-hand thread and with a corresponding device for fixing in a desired position with respect to the cutting edge and the cutting plane of the cutting elements.
In einer weiteren vorteilhaften Ausführungsform der erfindungsgemäßen Vorrichtung sind die Kerbelemente auf einem Kerbring angeordnet und die Schneidelemente auf einem Schneidring angeordnet, wobei Kerbring und Schneidring gesondert am Werkzeugkopf lösbar befestigt werden. Dadurch kann die Endmontage des Werkzeugkopfs erleichtert werden und die Gesamtheit der Schneidelemente auf leichte Art und Weise ausgewechselt werden. Dies ist insbesondere dann von Vorteil, wenn beispielsweise die Schneidelemente zunächst alle am Schneidring befestigt werden, um dann gemeinsam in ihre endgültige Form geschliffen zu werden. Dieser Art ist es möglich, die Schneidkanten aller einzelnen Schneidelemente auf dem Schneidring mit sehr geringen Toleranzen behaftet in die gleiche Schneidebene zu bringen. Das gleiche gilt für die Herstellung eines Kerbringes und den entsprechenden Kerbelementen. Alternativ ist es möglich eine Befestigung zwischen Schneidring und Kerbring vorzusehen, so dass keine Justage zwischen Schneidring und Kerbring erforderlich ist. Auch eine Anordnung von Kerbelementen auf dem Schneidring zwischen den einzelnen Schneidelementen oder wenigstens einigen Schneidelementen liegt ebenfalls im Rahmen der erfindungsgemäßen Vorrichtung. Im letzten Fall kann durch die Verschiebung der Kerbelemente zwischen die Schneidelemente ein größerer Radius der kreisförmigen Anordnung der Kerbelemente erreicht werden, so dass eine größere Anzahl von Kerbelementen auf dem Werkzeugkopf Platz finden kann. In diesem Fall wäre zusätzlich auch die Geschwindigkeit, mit der die Kerbelemente in die abgefräste Seite des Stapels blattförmiger Bedruckstoffe durch den größeren Radius vergrößert, was zu einer Verbesserung der Belastung der Kerbelemente führt.In a further advantageous embodiment of the device according to the invention, the notch elements are arranged on a notch ring and the cutting elements are arranged on a cutting ring, Kerbring and cutting ring are separately releasably secured to the tool head. Thereby, the final assembly of the tool head can be facilitated and the entirety of the cutting elements can be easily replaced. This is particularly advantageous if, for example, the cutting elements are all first fastened to the cutting ring, in order then to be ground together into their final shape. This type makes it possible to bring the cutting edges of all the individual cutting elements on the cutting ring with very small tolerances in the same cutting plane. The same applies to the production of a Kerbringes and the corresponding notch elements. Alternatively, it is possible to provide an attachment between cutting ring and Kerbring, so that no adjustment between the cutting ring and Kerbring is required. An arrangement of notch elements on the cutting ring between the individual cutting elements or at least some cutting elements is also within the scope of the device according to the invention. In the latter case, a larger radius of the circular arrangement of the notch elements can be achieved by the displacement of the notch elements between the cutting elements, so that a larger number of notch elements can find space on the tool head. In this case, in addition, the speed with which the notch elements in the milled side of the stack of sheet-shaped substrates increased by the larger radius, which leads to an improvement in the load of the notch elements would be in addition.
In einer weiteren Ausgestaltung der erfinderischen Vorrichtung ist auf der den blattförmigen Bedruckstoffen abgewandten Seite des Kerbringes mindestens ein Kerbelement angebracht. Dies ist insbesondere dann von Vorteil, wenn sich durch den Einbau des gewendeten Kerbringes in den Werkzeugkopf eine zweite bevorzugte Kerbtiefe erreichen lässt. Auf diese Weise kann eine Anpassung der Aufrautiefe zwischen zwei bevorzugten Aufrautiefen auf einfache Art und Weise erreicht werden.In a further embodiment of the inventive device at least one notch element is mounted on the side facing away from the sheet-shaped substrates of the Kerbringes. This is particularly advantageous if the installation of the turned Kerbringes in the tool head can achieve a second preferred notch depth. In this way, an adaptation of the roughness depth between two preferred roughness depths can be achieved in a simple manner.
In einer weiteren Ausgestaltung der erfindungsgemäßen Vorrichtung erfolgt eine Einstellung der Aufrautiefe durch Unterlegen des Kerbringes. Dabei wird, je nach gewünschter Aufrautiefe, eine geeignete Unterlegscheibe zwischen Kerbring und Werkzeugkopf eingelegt. Diese Unterlegung kann wahlweise zusätzlich zu einer stufenlosen Höhenverstellung, in Kombination mit einer stufenlosen Höhenverstellung oder anstelle einer stufenlosen Höhenverstellung der Aufrautiefe der Kerbelemente Verwendung finden. Ebenfalls liegt es im Rahmen der Erfindung, dass die gewünschte Aufrautiefe durch Kombination mehrerer Unterlegscheiben zwischen Kerbring und Werkzeugkopf erzielt wird. Es ist dem Fachmann klar, dass anstelle von Unterlegscheiben auch andere geeignete Mittel zum Unterlegen verwendet werden können.In a further embodiment of the device according to the invention, a setting of the roughening depth by placing the Kerbringes underlay. It is, depending on the desired roughness, a suitable washer between Kerbring and Tool head inserted. This underlay can optionally be used in addition to a stepless height adjustment, in combination with a stepless height adjustment or instead of a stepless height adjustment of the roughening depth of the notch elements. It is also within the scope of the invention that the desired Aufrautiefe is achieved by combining a plurality of washers between Kerbring and tool head. It will be apparent to those skilled in the art that other suitable underlaying means may be used instead of washers.
In einer besonders vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung sind die Schneidelemente an dem Schneidring angelötet, insbesondere bevor die Schneidelemente in ihre endgültige Form geschliffen werden. Dadurch wird zwar das Auswechseln einzelner Schneidelemente am Schneidring erschwert, dagegen ist aber keine weitere Justage der einzelnen Schneidelemente erforderlich. Insbesondere fallen auf diese Weise alle Montagetoleranzen der Schneidelemente untereinander weg. Alternative, nichtlösbare Verbindungsmethoden zur Verbindung zweier Metallteile können erfindungsgemäß ebenfalls zum Einsatz kommen.In a particularly advantageous embodiment of the device according to the invention, the cutting elements are soldered to the cutting ring, in particular before the cutting elements are ground to their final shape. Although this makes the replacement of individual cutting elements on the cutting ring difficult, but no further adjustment of the individual cutting elements is required. In particular fall in this way all mounting tolerances of the cutting elements away from each other. Alternative, non-detachable connection methods for connecting two metal parts can also be used according to the invention.
In einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung ist auf dem Werkzeugkopf eine Reinigungsbürste integriert. Die Reinigungsbürste ist auf der Oberfläche des Werkzeugkopfs im Bereich, der innerhalb der Anordnung der Schneidelemente liegt, angebracht und dient zu einer Verbesserung der Entstaubung der bearbeiteten Fläche des Stapels blattförmiger Bedruckstoffe.In a further advantageous embodiment of the device according to the invention, a cleaning brush is integrated on the tool head. The cleaning brush is mounted on the surface of the tool head in the area that lies within the arrangement of the cutting elements, and serves to improve the dedusting of the machined surface of the stack of sheet-like substrates.
In einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung wird durch die Rotation des Werkzeugkopfs gezielt ein Unterdruck im Bereich des Werkzeugkopfes erzeugt, der die bei der Bearbeitung entstehenden Staub- und Papierpartikel absaugt. Dies kann beispielsweise dadurch erreicht werden, dass eine Lüfterspirale im Zentrum der Frässcheibe vorgesehen ist, die vergleichbar mit dem Wirkprinzip eines Haartrockners durch die Rotation der Frässcheibe ein Luftstrom von der bearbeiteten Fläche des Stapels blattförmiger Bedruckstoffe weg erzeugt. Dadurch kann eine vorteilhafte Absaugung direkt am Entstehungsort der Staub- und Papierpartikel erreicht werden, was wiederum die Entstaubung fördert und damit durch die Verbesserung der Benetzung der Seitenränder der blattförmigen Bedruckstoffe durch das Klebemittel die Qualität der Klebebindung verbessert.In a further advantageous embodiment of the device according to the invention, a negative pressure in the region of the tool head is specifically generated by the rotation of the tool head, which sucks the dust and paper particles formed during processing. This can be achieved, for example, by providing a fan spiral in the center of the milling disk, which generates a flow of air away from the machined surface of the stack of sheet-like substrates, comparable to the operating principle of a hair dryer. As a result, an advantageous extraction can be achieved directly at the point of origin of the dust and paper particles, which in turn promotes the dedusting and thus the improvement the wetting of the side edges of the sheet-like substrates by the adhesive improves the quality of the perfect binding.
