Das bekannte Gerät ist von seiner Konstruktion her relativ kompliziert aufgebaut und bezüglich des Matenatverbrauchs zu seiner Herstellung - als zwangsläufige Folge der komplizierten Konstruktion - relativ aufwendig. Dies betrifft insbesondere die Ausführung der Auflageschnittleiste im Zusammenwirken mit der die Papier- bzw. Folienrolle tragenden Auflageplatte; bei dem bekannten Gerät schließt die Auftageschnittleiste unter einem rechten Winkel nach unten weisend an das vordere Ende der Auflageplatte an Zur Aufnahme der Kräfte, die beim Abtrennen einer Bahn aus Papier bzw. Folie auf die Auflageschnittleiste - auf die dem Schneidkanal direkt benachbarten Bereiche von Auflage- und Griffbereich einerseits und Stützbereich andererseits - wirken und zur Übertragung dieser Kräfte auf die Auflageplatte und über diese auf die Befestigungswand des Gerätes ist eine Mehrzahl von Versteifungsrippen vorgesehen, die die Rückseite der Auflageschnittleiste mit der Unterseite der Auflageplatte verbinden. - In diesem Zusammenhang ist noch zu bemerken, dass das bekannte Gerät aus Kunststoff besteht und im Spritzgießverfahren hergestellt ist.The known device is constructed relatively complicated in terms of its construction and relative to the Matenatverbrauchs for its production - as an inevitable consequence of the complicated construction - relatively expensive. This relates in particular to the execution of the support cutting bar in cooperation with the paper or film roll bearing support plate; in the known device the Auftageschnittleiste closes at a right angle pointing down to the front end of the support plate to absorb the forces that occur when separating a web of paper or foil on the support section - on the cutting channel directly adjacent areas of support and grip area on the one hand and support area on the other - act and to transfer these forces on the support plate and on this on the mounting wall of the device a plurality of stiffening ribs is provided which connect the back of the support bar with the underside of the support plate. - In this context, it should also be noted that the known device is made of plastic and is produced by injection molding.
Über die vorstehend genannten Nachteile hinaus hat dieses Gerät auch im Hinblick auf den Montageaufwand und seine Funktionalität gewisse Nachteile, die die Führung der Schneidschieber betreffen.In addition to the disadvantages mentioned above, this device has certain disadvantages with regard to the installation effort and its functionality, which relate to the leadership of the cutting slide.
Aus
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Gerät der eingangs genannten Gattung in dem Sinne weiter zu verbessern, dass es von der Konstruktion her wesentlich einfacher ausgeführt ist und dass zu seiner Herstellung bei mindestens gleicher Stabilität erheblich weniger Material (Kunststoff) notwendig ist. Ferner soll das Gerät dabei auch in ästhetischer Hinsicht verbessert werden insoweit, dass es ein gefälligeres, moderneres und in sich mehr geschlossenes Aussehen hat als das bekannte Gerät.The present invention has for its object to further improve a device of the type mentioned in the sense that it is much simpler in design and that for its production at least the same stability significantly less material (plastic) is necessary. Furthermore, the device should also be improved in aesthetic terms insofar that it has a pleasing, more modern and self-contained appearance than the known device.
Zur Lösung der vorstehend umrissenen Aufgabe wird vorgeschlagen, ein Gerät der zur Rede stehenden Art entsprechend dem Anspruch 1. auszuführen.To solve the above-outlined object, it is proposed to carry out a device of the type in question in accordance with
Ein mit der erfindungsgemäßen Lösung nach Anspruch 1 grundsätzlich erzielbarer wesentlicher Vorteil im Vergleich zum Gerät nach der
Ein weiterer Vorteil, der mit der im kennzeichnenden Teil des Anspruches 1 genannten Lösung verbunden ist besteht darin, dass das erfindungsgemäße Gerät der Ausdehnung des Auflage- und Griffbereiches der Auflageschnittleiste in Entnahmerichtung des Papiers bzw. der Folie sowie der Anzahl der enthaltenen Depots für Papier- bzw. Folienrollen entsprechend kürzer ausgeführt und entsprechend materialsparender hergestellt sein kann als das bekannte Gerät; dies deswegen, weil der Auflage- und Griffbereich der Auflageschnittleiste im Fall der Erfindung über der Ebene der Auflageplatte liegt und nicht darunter. Zudem ist durch den nach Innen geführten Griffbereich das Folienende zum Hochziehen wesentlich besser zu greifen.Another advantage that is associated with the solution mentioned in the characterizing part of
Schließlichresultiert aus der Tatsache, dass sich der Auflage- und Griffbereich der Auflageschnittleiste - zumindest im wesentlichen - über die Ebene der Auflageplatte erhebt der Vorteil oder die Möglichkeit, diesen Teil der Auflageschnittleiste zugleich als eine die Papier- bzw. Folienrolle haltende Querleiste zu nutzen; dadurch entfällt die zu diesem Zweck bei dem bekannten Gerät auf der Auflageplatte gesondert vorgesehene Querleiste.Finally, resulting from the fact that the support and grip portion of the support bar - at least substantially - rises above the plane of the platen advantage or the ability to use this part of the support bar at the same time as a paper or foil roll holding cross bar; This eliminates the purpose for this purpose in the known device on the support plate separately provided transverse bar.
Eine weitere, neben den oben erwähnten Vorteilen mögliche Verbesserung eines zur Rede stehenden Gerätes ergibt sich dadurch, dass der zum Abtrennen einer Bahn aus Papier bzw. Folie an der Abdeckung des Gerätes verschiebbar geführte Schneidschieber nicht - wie bei dem bekannten Gerät - in einer in der Abdeckung gesondert vorgesehenen Führung geführt ist, sondern direkt an der oberen Begrenzungskante der dem Depot zugeordneten Öffnung geführt ist. Hierzu sind im Detail verschiedene Lösungen möglich; auf die bevorzugte Lösung gemäß den Ansprüchen 12 und 13 wird schon an dieser Stelle hingewiesen.Another, in addition to the above-mentioned advantages possible improvement of a device in question results from the fact that for cutting a web of paper or foil on the cover of the device slidably guided cutting slide not - as in the known device - in one in the Cover is provided separately provided guide, but is guided directly to the upper boundary edge of the depot associated opening. For this purpose, various solutions are possible in detail; to the preferred solution according to
Schließlich ergibt sich eine weitere mögliche Verbesserung eines zur Rede stehenden Gerätes dadurch, dass die Auflageplatte für die Papier- bzw. Folienrolle schräg nach vom geneigt ist und damit zumindest im wesentlichen die erwünschte, in Richtung auf den erwähnten Durchlassschlitz zu abfallend geneigte Führungsebene für die Papier- bzw. Folienrolle bildet.Finally, a further possible improvement of a device in question results from the fact that the support plate for the paper or film roll is inclined obliquely from and thus at least substantially the desired, in the direction of said passage slot to sloping inclined guide plane for the paper - or film roll forms.
Zu diesem Zweck ist im Fall des bekannten Gerätes eine Mehrzahl gesonderter, zur Rückwand - zu Rückwandbereichen - des Gerätes hin ansteigend ausgeführter Rippen vorgesehen, die sich auf der hier horizontal ausgerichteten Auflageplatte befinden und die die erwähnte Führungsebene bilden. - In diesem Zusammenhang ist noch zu erwähnen, dass bei der Erfindung wegen des Fehlens der erwähnten Rippen auch auf entsprechende Rückwandbereiche zur "Anbindung" solcher Rippen verzichtet werden kann.For this purpose, in the case of the known device, a plurality of separate, to the rear wall - to back wall areas - of the device rising towards ribs provided, which are located on the here horizontally oriented support plate and which form the mentioned management level. - In this context, it should also be mentioned that in the invention due to the absence of the mentioned ribs can also be dispensed with corresponding back wall areas for "connection" of such ribs.
Vorteilhafte oder zweckmäßige, Weiterbildungen sind in den Ansprüchen 2 bis 13 angegeben.Advantageous or expedient, further developments are specified in
Anspruch 2 nennt eine bevorzugte Ausgestaltung für den Auflage- und Griffbereich der Auflagechnittleiste des Gerätes, bei der die obere, freie Kante des Auflage- und Griffbereiches die Funktion einer Haltekante für die Papier- bzw Folienrolle erhält. Anspruch 3 betrifft dazu eine vorteilhafte Bemessung der Ausdehnung des Auflage- und Griffbereiches.
In den Ansprüchen 4 bis 6 werden verschiedene mögliche und zweckmäßige Gestaltungen des Auflage- und Griffbereiches der Auflageschnittleiste angegeben.In the
Die Ansprüche 7 bis 10 nennen alternative Lösungen für im wesentlichen denjenigen Bereich des erfindungsgemäßen Gerätes, der die Auflageschnittleiste und das daran anschließende vordere Ende der Auflageplatte sowie den innerhalb des Bereiches der Auflageschnittleiste befindlichen Schneidkanal umfasst.The

Die in vertikaler Richtung hintereinanderliegenden Bereiche 18 und 19 der Abdeckung 5 schließen die schon erwähnte Öffnung 6 der Abdeckung 5 ein, während der Bereich 19 und ein mit 20 bezeichneter Bereich der Abdeckung 5 die schon erwähnte Öffnung 7 der Abdeckung 5 einschließen.The
Die Fortsätze 16, 17 der Auflageplatte 13 bzw. 14 gehören - als Anformungen der Auflageplatte 13 bzw. 14 - zum Gehäuse 2 und bilden einen Auflage- und Griffbereich 21 bzw. 22 eines zusammenfassend als Auflageschnittleiste 23 bzw. 24 bezeichneten Bereiches des Gerätes 1. Auf den Auflage- und Griffbereich 21 bzw. 22 der Auflageschnittleiste 23 bzw. 24 folgt nach unten zu ein Stützbereich 25 bzw. 26 der Auflageschnittleiste 23 bzw. 24, der zur Abdeckung 5 gehört.The
In der Auflageschnittleiste 23 bzw. 24 befindet sich ein parallel zur Längsrichtung der Auflageplatte 13 bzw. 14 verlaufender Schneidkanal 27 bzw. 28, der dem Schneidmesser des Schneidschiebers 8 bzw. 9 zugeordnet ist. Der Schneidkanal 27 bzw. 28 ist einerseits durch eine Kante 29 des in Entnahmerichtung des Papiers bzw. der Folie vor dem Schneidkanal 27 bzw. 28 liegenden Auflage- und Griffbereiches 21 bzw. 22 der Auflageschnittleiste 23 bzw. 24 und andererseits durch eine Kante 30 des in Entnahmerichtung des Papiers bzw. der Folie auf den Auflage- und Griffbereich 21 bzw. 22 folgenden Stützbereiches 25 bzw. 26 der Auflageschnittleiste 23 bzw. 24 begrenzt.In the
Die beim Gebrauch des Gerätes 1 von der Oberseite des Stützbereiches aufgenommenen Druckkräfte werden von einem an die Auflageplatte 13 bzw. 14 nach unten weisend angeformten Fortsatz 31 bzw. 32 in die Auflageplatte 13 bzw. 14 geleitet, während die von der Oberseite des Auflage- und Griffbereiches aufgenommenen Druckkräfte in der Nähe des Schneidkanals direkt in die Auflageplatte 13 bzw. 14 geleitet werden.The recorded during use of the
Der durch den Fortsatz 16 bzw. 17 gebildete Auflage- und Griffbereich 21 bzw. 22 der Auflageschnittleiste 23 bzw. 24 des Gerätes 1 weist eine obere, freie Kante auf, die die Funktion einer Haltekante 33 bzw. 34 für die Folienrolle 10 bzw. 11 erhält. Diese Haltekante 33 bzw. 34 reicht im Fall des Ausführungsbeispiels bis auf eine etwa dem halben Durchmesser der Folienrolle 1.0 bzw. 11 entsprechende Höhe. Dabei verläuft der über der Ebene der Auflageplatte 13 bzw. 14 liegende Teil des Auflage und Griffbereiches 21 bzw. 22 der Auftageschnittleiste 23 bzw. 24 vom Schneidkanal 27 bzw. 28 ausgehend in Richtung auf das Depot 3 bzw. 4 für die Folienrolle 10 bzw. 11 zu schräg geneigt und ist zusätlich in gewissem Ausmaß im Querschnitt konvex gekrümmt ausgeführt. - Eine gewisse Rauhigkeit (der Vorderseite) des Auflage- und Griffbereiches 21 bzw. 22 sorgt dafür, dass trotz der von der Kunststofffolie ausgehenden Adhäsionskräfte ein relativ leichtes Abnehmen bzw. Abheben der Folie vom Auflage- und Griffbereich 21 bzw. 22 möglich ist.The supporting and gripping
Der Schneidschieber 8 bzw. 9 ist direkt an der oberen, mit 35 bzw. 36 bezeichneten Begrenzungskante der Öffnung 6 bzw. 7 der Abdeckung 5 verschiebbar geführt (siehe auch
Die konstruktive Gestaltung dieser Fortsätze in Verbindung mit den Eigenschaften des zum Herstellen der Schneidschieber 8, 9 verwendeten Kunststoffes ermöglicht eine gewisse Elastizität zwischen den Fortsätzen 49, 50 und dem diesen Fortsätzen gegenüberliegenden Ende 41 des vorderen Wandungsteils 43 des Schneidschiebers 8 bzw. 9, so dass der Schneidschieber 8 bzw. 9 mit einer gewissen Schnappwirkung auf die Begrenzungskante 35 bzw. 36 der Abdeckung 5 aufgesteckt oder von dieser abgezogen werden kann. - Bei dieser Lösung führt sich der Schneidschieber 8 bzw. 9 beim Abtrennen einer Bahn/eines Stückes der Folie von der Folienrolle 10 bzw. 11 retativ leichtgängig an der Begrenzungskante 35 bzw. 36 der Abdeckung 5.The structural design of these extensions in conjunction with the properties of the plastic used for producing the cutting
