Description

Die Erfindung betrifft eine Bogenstanz- und PrƤgemaschine mit einem Maschinengestell, mit zwei an dem Maschinengestell befestigten FĆ¼hrungsschienen, wobei diese jeweils innen an gegenĆ¼berliegenden Seiten des Maschinengestells befestigt sind und wobei jede der FĆ¼hrungsschienen aus mindestens einem Grundkƶrper gebildet ist und Ketten- und FĆ¼hrungsbahnen umfasst, die mit Gleitleisten belegt sind, mit zwei endlosen Ketten, die in den Kettenbahnen gefĆ¼hrt sind und mit Greifereinrichtungen, die an den Ketten befestigt und mittels Rollen in den FĆ¼hrungsbahnen gefĆ¼hrt sind.The invention relates to a sheet punching and embossing machine with a machine frame, with two attached to the machine frame guide rails, which are respectively mounted inside on opposite sides of the machine frame and wherein each of the guide rails is formed from at least one main body and chain and guideways, comprising are covered with sliding strips, with two endless chains, which are guided in the chain tracks and with gripper devices which are attached to the chains and guided by rollers in the guideways.

Solche Bogenstanz- und PrƤgemaschinen werden eingesetzt, um zum Beispiel Bogen aus Papier oder Karton fĆ¼r die Herstellung von Zuschnitten zu stanzen beziehungsweise zu prƤgen. HierfĆ¼r werden die Bogen von einem Stapel entnommen und diskontinuierlich mittels einer Greifereinrichtung durch die Maschine transportiert. Die Greifereinrichtung ist mittels zweier Ketten gefĆ¼hrt, die endlos in zwei zugeordneten FĆ¼hrungsbahnen angeordnet sind. Solche Bogenstanz- und PrƤgemaschinen sind zum Beispiel in der DE 102 44 585 A1 beschrieben.Such sheet punching and embossing machines are used, for example, to punch or emboss sheets of paper or cardboard for the production of blanks. For this purpose, the sheets are removed from a stack and transported discontinuously by means of a gripper device through the machine. The gripper device is guided by means of two chains, which are arranged endlessly in two associated guideways. Such sheet punching and embossing machines are for example in the DE 102 44 585 A1 described.

Die DE 30 44 084 C2 beschreibt eine Bogen verarbeitende Maschine, bei der eine Greifereinrichtung an ihren Enden an je einer Kette befestigt ist. Die Ketten sind jeweils in zugeordneten Kufen gelagert. Weiterhin ist eine an der Greifereinrichtung angeordnete Rolle in neben den Kufen angeordneten FĆ¼hrungsbahnen gefĆ¼hrt. Die Kufen und die FĆ¼hrungsbahnen sind Teil eines Maschinengestells. Gleitleisten sind an den Kufen und den FĆ¼hrungsbahnen nicht angeordnet. Dies hat den Nachteil einer hohen GerƤuschentwicklung wƤhrend des Betriebs der Maschine im Betrieb und gleichzeitig tritt hierbei ein hoher VerschleiƟ auf. Eine Reparatur ist nur mit sehr hohem Aufwand mƶglich.The DE 30 44 084 C2 describes a sheet-processing machine in which a gripper device is attached at its ends to a respective chain. The chains are each stored in associated runners. Furthermore, a roller arranged on the gripper device is guided in guide rails arranged next to the skids. The runners and the guideways are part of a machine frame. Sliding strips are not arranged on the skids and the guideways. This has the disadvantage of high noise during operation of the machine during operation and at the same time occurs here on a high wear. A repair is possible only with great effort.

Weiterhin ist es aus einem Prospekt "WPM 400" der Fa. Jagenberg bekannt, Ketten beidseitig in kunststoffbeschichteten Kettenbahnen zu fĆ¼hren. Die an den Ketten befestigten Greiferwagen laufen zusƤtzlich in separaten, ebenfalls kunststoffbeschichteten FĆ¼hrungsbahnen parallel zu den Kettenbahnen. Die Kunststoffschichten (Gleitleisten) sind auf die entsprechenden FlƤchen der Ketten- und FĆ¼hrungsbahnen aufgegossen. Dies hat den Nachteil, dass die geforderte ProzeƟsicherheit nur mit sehr hohem Aufwand sichergestellt werden kann.Furthermore, it is known from a brochure "WPM 400" of the company. Jagenberg to lead chains on both sides in plastic-coated chain lanes. The gripper carriages attached to the chains also run in separate, likewise plastic-coated guideways parallel to the chain tracks. The plastic layers (wear strips) are poured onto the corresponding surfaces of the chain and guideways. This has the disadvantage that the required process reliability can be ensured only with great effort.

Aufgabe der Erfindung ist es, eine Bogenstanz- und PrƤgemaschine zu schaffen, bei der Gleitleisten von Ketten- und FĆ¼hrungsbahnen einfacher zu fertigen und deutlich verschleiƟfester sind.The object of the invention is to provide a sheet punching and embossing machine, are easier to manufacture in the sliding strips of chain and guideways and are much more resistant to wear.

Die Aufgabe ist dadurch gelƶst, dass in die FĆ¼hrungsschienen im Bereich der Ketten- und FĆ¼hrungsbahnen Nuten mit rechteckigem Querschnitt eingelassen sind und dass die Gleitleisten fĆ¼r die Ketten- und FĆ¼hrungsbahnen getrennt sind und einen T- fƶrmigen Querschnitt aufweisen, wobei die Stege der Gleitleisten in die Nuten eingesetzt sind. In die FĆ¼hrungsschienen sind im Bereich der Ketten- und FĆ¼hrungsbahnen Nuten mit rechteckigem Querschnitt eingelassen; die Gleitleisten weisen einen T- fƶrmigen Querschnitt auf, wobei die Stege des T in die Nuten eingesetzt sind. Dies bewirkt, dass die Gleitleisten einfach zu montieren sind, wobei gleichzeitig eine genaue Lagejustierung erfolgt. Die OberflƤchen der FĆ¼hrungsschienen bedĆ¼rfen keiner besonderen Beschaffenheit und/oder Vorbehandlung, wie dies bei einem GieƟverfahren der Fall ist.The object is achieved in that in the guide rails in the region of the chain and guideways grooves are inserted with a rectangular cross-section and that the slide strips for the chain and guideways are separated and have a T-shaped cross-section, wherein the webs of the sliding strips in the Grooves are used. In the guide rails grooves with rectangular cross-section are embedded in the field of chain and guideways; the slide strips have a T-shaped cross-section, wherein the webs of the T are inserted into the grooves. This causes the wear strips are easy to assemble, at the same time a precise position adjustment takes place. The surfaces of the guide rails require no special properties and / or pretreatment, as is the case with a casting process.

Dadurch dass die Gleitleisten fĆ¼r die Ketten- und FĆ¼hrungsbahnen getrennt sind, kann der Austausch dem unterschiedlichen VerschleiƟ angepasst werden.The fact that the slide rails for the chain and guideways are separated, the replacement can be adapted to the different wear.

Die UnteransprĆ¼che betreffen die vorteilhafte Ausgestaltung der Erfindung.The subclaims relate to the advantageous embodiment of the invention.

Die mechanische Befestigung der Stege in den Nuten bewirkt, dass die Gleitleisten unverrĆ¼ckbar gehalten sind. Hierbei hat sich die Verwendung von SpannhĆ¼lsen fĆ¼r die Montage und Demontage als besonders vorteilhaft erwiesen.The mechanical attachment of the webs in the grooves causes the slide strips are held immovable. Here, the use of clamping sleeves for assembly and disassembly has proven to be particularly advantageous.

Stahl ist wegen seiner Festigkeit und guten WƤrmeleitfƤhigkeit fĆ¼r die Fertigung der FĆ¼hrungsschienen besonders gut geeignet.Due to its strength and good thermal conductivity, steel is particularly well suited for the production of guide rails.

FĆ¼r die Gleitleisten werden bevorzugt Kunststoffe eingesetzt. Modifiziertes Polyamid ist ein Kunststoff, der gĆ¼nstige Gleiteigenschaften und eine hohe Festigkeit aufweist. Durch die hohe Festigkeit kann die Aufbauhƶhe der FĆ¼hrungschiene reduziert und platzsparend eingesetzt werden. Durch die lebenslange Selbstschmierung des Kunststoff sind geringe Gleitreibungswerte garantiert. Ein bevorzugt eingesetztes modifiziertes Polyamid ist MurlubricĀ® von der Firma Murtfeldt.Plastics are preferably used for the sliding strips. Modified polyamide is a plastic that has favorable sliding properties and high strength. Due to the high strength, the installation height of the guide rail can be reduced and used to save space. Lifelong self-lubrication of the plastic guarantees low sliding friction values. A preferred modified polyamide used is MurlubricĀ® from Murtfeldt.

Durch die geringe Aufbauhƶhe des Kunststoff ist eine optimale WƤrmeableitung garantiert und eine lange Lebensdauer der FĆ¼hrungskette sichergestellt.The low installation height of the plastic guarantees optimal heat dissipation and ensures a long service life of the guide chain.

Eine Bogenstanz- und PrƤgemaschine umfasst im Wesentlichen einen Anleger, eine PrƤgestation, eine Stanzstation, einen Ausbrecher, und eine Ablagestation, die in einem in den Figuren nur angedeuteten Maschinengestell 1 zusammengefasst sind.A sheet punching and embossing machine essentially comprises a feeder, an embossing station, a punching station, a breaker, and a storage station, which are combined in a machine frame 1 only indicated in the figures.

In dem Maschinengestell 1 sind zwei Ketten 3 zum Transportieren von Bogen gefĆ¼hrt, wobei jede der Ketten 3 in einer zugeordneten FĆ¼hrungsschiene 2 gelagert ist. An jeder LƤngsseite des Maschinengestells 1, das ist in einer Transportrichtung gesehen links und rechts von den Bogen, ist jeweils eine der FĆ¼hrungsschienen 2 in einer vorbestimmten Hƶhe zum Beispiel mittels Schrauben befestigt. Jede FĆ¼hrungsschiene 2 umfasst einen oberen und einen unteren Grundkƶrper 2a, 2b, die einen vorbestimmten Abstand zueinander aufweisen. Zwischen den Ketten 3 sind wie bekannt in definierten AbstƤnden Greifereinrichtungen 4 angeordnet und an ihren Enden an den Ketten 3 befestigt.In the machine frame 1, two chains 3 are guided for transporting sheets, wherein each of the chains 3 is mounted in an associated guide rail 2. On each longitudinal side of the machine frame 1, which is seen in a transport direction left and right of the arc, one of the guide rails 2 is fixed at a predetermined height, for example by means of screws. Each guide rail 2 comprises an upper and a lower base body 2a, 2b, which have a predetermined distance from one another. As is known, gripper devices 4 are arranged between the chains 3 at defined intervals and fastened to the chains 3 at their ends.

Jede Kette 3 ist als Rollenkette ausgebildet und in der zugeordneten FĆ¼hrungsschiene 2 in einer hierin ausgebildeten Kettenbahn 6 gelagert. Die Kettenbahn 6 weist zwei parallele, vertikal beabstandete ebene erste FlƤchen 8a auf. Diese sind auf den Grundkƶrpern 2a, 2b senkrecht an das Maschinengestell 1 angrenzend in einer Breite ausgebildet, die dem Abstand zweier gegenĆ¼berliegender Innenlaschen 3a der Kette 3 abzĆ¼glich einem vorbestimmten Spiel entspricht. Die Breite betrƤgt zum Beispiel 16 mm.Each chain 3 is designed as a roller chain and mounted in the associated guide rail 2 in a chain track 6 formed therein. The chain track 6 has two parallel, vertically spaced planar first surfaces 8a. These are formed on the base bodies 2a, 2b perpendicular to the machine frame 1 adjacent in a width corresponding to the distance between two opposing inner plates 3a of the chain 3 minus a predetermined game. The width is for example 16 mm.

Jede Greifereinrichtung 4 weist eine erste FĆ¼hrungsrolle 9 mit horizontaler Drehachse auf, die in einer in der FĆ¼hrungsschiene 2 ausgebildeten FĆ¼hrungsbahn 7 gefĆ¼hrt ist. Die FĆ¼hrungsbahn 7 weist zwei parallele, vertikal beabstandete ebene zweite FlƤchen 8b auf. Die Breite der FĆ¼hrungsbahn 7 entspricht der Breite der Kettenbahn 6.Each gripper device 4 has a first guide roller 9 with a horizontal axis of rotation, which is guided in a guideway 7 formed in the guide rail 2. The guideway 7 has two parallel, vertically spaced planar second surfaces 8b. The width of the guide track 7 corresponds to the width of the chain track 6.

Weiterhin ist an jeder Greifereinrichtung 4 eine zweite FĆ¼hrungsrolle 13 mit vertikaler Drehachse angeordnet. Die zweite FĆ¼hrungsrolle 13 berĆ¼hrt unmittelbar eine zugewandte SeitenflƤche des oberen Grundkƶrpers 2a.Furthermore, a second guide roller 13 with a vertical axis of rotation is arranged on each gripper device 4. The second guide roller 13 directly contacts a facing side surface of the upper base body 2a.

Jede der ersten und zweiten FlƤchen 8a, 8b ist separat mit einer Gleitleiste 11 belegt. HierfĆ¼r ist in jede der ersten und zweiten FlƤchen 8a, 8b eine Nut 10 mit rechteckigem Querschnitt eingelassen. Jede Gleitleiste 11 weist einen T- fƶrmigen Querschnitt auf, wobei eine StƤrke eines Stegs der Gleitleiste 11 einer Weite der Nut 10 entspricht. Ein T ist definiert als zusammengesetzt aus einem waagerechten Gurt und einem daran angesetzten, senkrecht nach unten weisenden Steg. Der Gurt der Gleitleiste 11 hat eine Breite entsprechend der Breite der ersten und zweiten FlƤchen 8a, 8b. Die Dicke des Gurtes der Gleitleiste 11, also die Dicke der Gleitleisten 11, betrƤgt zum Beispiel 4,5 mm. In jede der Nuten 10 ist jeweils ein Steg der Gleitleisten 11 ohne seitliches Spiel so eingelassen, dass jede Gleitleiste 11 auf der zugehƶrigen ersten oder zweiten FlƤche 8a, 8b unmittelbar anliegt. HierfĆ¼r ist die Tiefe jeder Nut 10 geringfĆ¼gig grĆ¶ĆŸer als die LƤnge des Stegs der Gleitleisten 11. Anzumerken bleibt, dass der Steg, wie auch die Nut 10, eine leicht konische Form aufweisen kann, so dass die Gleitleiste 11 zum Beispiel leichter demontiert ist.Each of the first and second surfaces 8a, 8b is covered separately with a sliding strip 11. For this purpose, a groove 10 of rectangular cross-section is embedded in each of the first and second surfaces 8a, 8b. Each slide strip 11 has a T-shaped cross-section, wherein a thickness of a web of the slide strip 11 corresponds to a width of the groove 10. A T is defined as being composed of a horizontal strap and a vertically downwardly facing web. The belt of the slide bar 11 has a width corresponding to the width of the first and second surfaces 8a, 8b. The thickness of the belt of the slide strip 11, ie the thickness of the slide strips 11, is for example 4.5 mm. In each of the grooves 10, a web of the wear strips 11 is inserted in each case without lateral play so that each slide strip 11 directly abuts on the associated first or second surface 8a, 8b. For this purpose, the depth of each groove 10 is slightly larger than the length of the web of the wear strips 11. It should be noted that the web, as well as the groove 10, may have a slightly conical shape, so that the slide strip 11, for example, is easier disassembled.

Der lichte Abstand zwischen den Kettbahnen 6 zugeordneten Gleitleisten 11 entspricht dem AuƟendurchmesser von Kettenrollen der Kette 3, so dass eine FĆ¼hrung in der Hƶhe definiert ist; die Innenlaschen 3a greifen Ć¼ber Seitenflanken der zugeordneten Gleitleisten 11 und geben so der Kette 3 auch eine seitliche FĆ¼hrung. Der lichte Abstand zwischen den den FĆ¼hrungsbahnen 7 zugeordneten Gleitleisten 11 entspricht dem AuƟendurchmesser der ersten FĆ¼hrungsrollen 9.The clear distance between the warp tracks 6 associated wear strips 11 corresponds to the outer diameter of chain rollers of the chain 3, so that a guide is defined in height; the inner plates 3a engage over side flanks of the associated wear strips 11 and thus give the chain 3 also a lateral guidance. The clear distance between the guideways 7 associated slide strips 11 corresponds to the outer diameter of the first guide rollers. 9

Die Gleitleisten 11 sind mechanisch mittels ihrer Stege in den Nuten 10 befestigt. Hierbei ist ein bestimmter Halt durch die spielfrei abgestimmte Passform der Stege und der Nuten 10 gegeben. Weiterhin sind Durchgangsbohrungen in die Grundkƶrper 2a, 2b und in die Stege der Gleitleisten 11 eingelassen. In jede Durchgangsbohrung ist eine SpannhĆ¼lse 12 eingetrieben. Hierdurch sind die Gleitleisten 11 unverrĆ¼ckbar und lƶsbar an den Grundkƶrpern 2a, 2b befestigt.The slide strips 11 are mechanically fastened by means of their webs in the grooves 10. Here, a certain hold is given by the play matched fit of the webs and the grooves 10. Furthermore, through holes in the main body 2a, 2b and in the webs of the slide strips 11 are embedded. In each through hole a clamping sleeve 12 is driven. As a result, the wear strips 11 are immovably and releasably attached to the basic bodies 2a, 2b.

Alternativ zu den SpannhĆ¼lsen 12 sind zum Beispiel Passstifte oder Schrauben angeordnet.As an alternative to the clamping sleeves 12, for example, dowel pins or screws are arranged.

Die Grundkƶrper 2a, 2b sind aus Stahl gefertigt. Dies bewirkt eine hohe StabilitƤt und eine gute WƤrmeableitung. Durch die Auswahl eines geeigneten Kunststoffs, wie beispielsweise modifiziertes Polyamid und bevorzugt MurlubricĀ®, und die grĆ¶ĆŸere AnlageflƤche der Gleitleisten, die im Bereich der Nut 10 und der FlƤchen 8a, 8b mit der FĆ¼hrungsschiene in Kontakt stehen, ist auch fĆ¼r eine verbesserte WƤrmeableitung von der FĆ¼hrungsrolle 9 und der Kette 3 zum Maschinengestell gesorgt. Dies bietet wiederum den Vorteil, dass die Lebensdauer der Gleitpartner 3, 9, 11 erhƶht wird.The main body 2a, 2b are made of steel. This ensures high stability and good heat dissipation. By selecting a suitable plastic, such as modified polyamide and preferably MurlubricĀ®, and the larger contact surface of the sliding strips, which are in the region of the groove 10 and the surfaces 8 a, 8 b in contact with the guide rail, is also for improved heat dissipation of the Guide roller 9 and the chain 3 provided to the machine frame. This in turn offers the advantage that the life of the sliding partners 3, 9, 11 is increased.

Die Gleitleisten 11 sind aus einem modifizierten Gusspolyamid gefertigt. Dieses Polyamid weist eine Legierung mit SpezialzusƤtzen und eine hochkristalline Struktur auf, in die mineralisches Ɩl fest eingebunden ist. Hierdurch sind die Gleitleisten 11 dauerhaft selbstschmierend und weisen geringe Reibung und einen entsprechend geringen VerschleiƟ auf. Weiterhin ist das Polyamid relativ hart (Shore- HƤrte 75) und mechanisch fest.The wear strips 11 are made of a modified cast polyamide. This polyamide has an alloy with special additives and a highly crystalline structure, in which mineral oil is firmly integrated. As a result, the wear strips 11 permanently self-lubricating and have low friction and a correspondingly low wear. Furthermore, the polyamide is relatively hard (Shore hardness 75) and mechanically strong.
