Definitions
- the invention relates to a material cutting and feeding device and a window gluing machine according to the preamble of claim 1 or 13.
- U.S. 10,232,579 B2 describes a window gluing machine for gluing film sections cut to length from a film roll onto windowed carton blanks for the production of packaging cartons.
- a film web lying on a V-shaped suction belt section of a revolving suction belt is moved from the suction belt in the direction corresponding to the window length lifted onto a cutting blade by means of a clocked film web retainer.
- the cutting blade is positioned vertically and in the middle between two deflection rollers of the suction belt V and cuts through the film web, forming the film sections, which then fall back onto the suction belt at a distance between the cutting edges.
- the film sections produced in this way are stripped off by the suction belt onto the carton blanks that are glued around the window and connected to these to form film window cartons.
- the known device is limited in such a way that short window sections cannot be reliably implemented.
- the deflection rollers cannot be arranged arbitrarily close to each other and the short film sections that can be achieved in this way are neither reliably sucked onto the suction belt nor released by it.
- the complexity of gluing increases in the case of short film sections, resulting in quality problems with the nozzle device, in particular in the form of traces of glue on the windows.
- the nozzles are maintenance-intensive. Overall, with the known window gluing machine, unclean and incomplete separations, detachments and unclean gluing occur in the case of short film sections. Uninterrupted operation is not possible and the operating costs are high.
- the invention is therefore based on the object of creating a material cutting and feeding device and window gluing machine according to the preamble of claim 1 or 13, which enable shorter window lengths with improved production quality and reduced maintenance costs.
- the distance between the cutting tool and the material-removing deflection can be less than 70mm, less than 60mm, less than 50mm, or 55mm +- 1mm, +-2mm, +-3mm or +-5mm. It can be 2% to 48%, preferably 5% to 40%, 10% to 30% or 10% to 20% of the distance between the material-removing and material-feeding deflection.
- the distance is expediently measured along a tangent extending from the cutting edge in the direction of the deflection.
- the window gluing machine 1 shown comprises a feed device 2 for window blanks 3, which, after application of glue 4 by a gluing device 5 in the transport direction 6, by a material cutting and feeding device 7 with a film roll 8 via a strain relief 9 onto a suction belt 11 interacting with a cutting tool 10 cut to length window film sections 12 for the production of film window boxes 13 or the like are occupied.
- the basic structure of the gluing device 5, the strain relief 9 and the material cutting and feeding device 7 is from U.S. 10,232,579 B2 known, the content of which is hereby referred to.
- the cutting tool 10 here is a knife, possibly with a serrated edge and/or with points, with a cutting edge 17 facing the suction belt 11, which is arranged closer to the deflection 16 on the discharge side than on the deflection 14 on the supply side.
- a distance 18 is preferably less than 20mm.
- the cutting tool 10 and/or the cutting edge 17 is/are preferably inclined at an angle ⁇ >0° to the direction of advance relative to the vertical, see FIG 2 .
- the angle ⁇ can be between 5° and 10°.
- the cutting tool 10 and/or the cutting edge 17 can also be arranged transversely to the feed direction at an angle ⁇ >0°, see FIG 3 .
- the angle ⁇ is advantageously between 10° and 15°.
- a stripping device 23 for stripping the material sections 12 from the suction belt 11 can be provided on a lower deflection 22, see FIG 4 .
- a pressing device 24 expediently of identical construction, can be provided for pressing the material sections onto the suction belt, see FIG figure 5 .
- the devices 23, 24 expediently have fingers 25, for example as in 6 shown in the form of comb-like spaced and contoured metal sheets, in particular designed in the shape of arc sections, which engage in recesses or grooves in deflection device 21 or advance roller 22 and possibly in suction belt 11 and/or can be angularly adjustable and/or pivotably mounted on a shaft 26 for maintenance purposes.
- the sheets can be 0.2mm to 1mm or be up to 2mm thick or have a contact surface of up to 5mm or 10mm wide with the film web due to an L- or U-shaped bend.
- a contour of the stripping device 23 can taper against the feeding direction of the film sections 12 and/or a contour of the pressing device 24 can taper against the feeding direction of the film 19, see FIG 4 or 5.
- the gluing device 5 has both a nozzle device 27 for gluing in the feed direction 28 and a cliché device 29 for gluing transversely to the feed direction 28, see FIG 7 .
- the cliché device 29 preferably extends along the length of the window cutouts 30.
- the nozzle device 27 can preferably have one or, as shown by way of example, several nozzles 31 spaced transversely to and/or in the feed direction 28 here.
- the nozzle device 27 places gluing points and/or gluing lines on the blanks under program control, in particular adjacent to the window section 30. Both the nozzle and the cliché device can extend over the entire width of the web, since the program control and/or the cliché exchange requires an individual gluing adjustment enable cutting.
- FIG. 8 illustrates a further embodiment of the material cutting and feeding device 7 with 1 opposite transport direction 6. Instead of two deflections on the underside, only one wider deflection 22 is used.
- the cutting-to-length device with the cutting-to-length tool 10 and the feed roller 21 cannot be arranged very close to one another when technically implemented, see FIG 9 , Which is why the cutting tool 10 can be arranged eccentrically to the deflection 15 and thus closer to the deflection 16 than to the deflection 14, as shown.
- the cutting tool 10 can have an angled free cutting end in all of the embodiments, or it can be set at an angle overall in order to bring the cutting edge 17 even closer to the deflection 16 .
- a distance between the cutting edge 17 and the axis of the deflection roller 15 is expediently more than 0.5 cm, 1 cm or 2 cm, see FIG Figures 9 to 12 .
- the distance 18 can be dimensioned along a deflection tangent extending from the cutting edge 17 in the direction of the discharge-side deflection 16 to the pressing position 32 there for the film web 19 .
- FIG 13 illustrates the lower scraping device 23 with fingers which engage in grooves of the suction belt 11 and/or the deflection 22.
- the material cutting and feeding device, the stripping device, the pressing device and the gluing device are each independent and divisible inventive concepts that are preferably used together in a window gluing machine.

Description
Die Erfindung betrifft eine Materialabläng- und -zuführvorrichtung sowie eine Fensterklebemaschine nach dem Oberbegriff es Anspruchs 1 bzw. 13.The invention relates to a material cutting and feeding device and a window gluing machine according to the preamble of
Die bekannte Vorrichtung ist hinsichtlich der Trennqualität und -größe dergestalt eingeschränkt, dass kurze Fensterabschnitte nicht zuverlässig realisierbar sind. So können die Umlenkrollen nicht beliebig nahe aneinander angeordnet werden und die so erzielbaren kurze Folienabschnitte werden weder zuverlässig auf den Saugriemen angesaugt, noch von diesem freigegeben. Zudem steigt die Beleimungskomplexität bei kurzen Folienabschnitten, wodurch Qualitätsprobleme bei der Düseneinrichtung insbesondere in Form von Leimspuren auf den Fenstern entstehen. Ferner sind die Düsen wartungsintensiv. Insgesamt kommt es bei der bekannten Fensterklebemaschine bei kurzen Folienabschnitten zu unsauberen und unvollständigen Trennungen, zu Ablösungen und unsauberen Verklebungen. Ein unterbrechungsfreier Betrieb ist nicht möglich und die Betriebskosten sind hoch.With regard to the quality and size of the separation, the known device is limited in such a way that short window sections cannot be reliably implemented. The deflection rollers cannot be arranged arbitrarily close to each other and the short film sections that can be achieved in this way are neither reliably sucked onto the suction belt nor released by it. In addition, the complexity of gluing increases in the case of short film sections, resulting in quality problems with the nozzle device, in particular in the form of traces of glue on the windows. Furthermore, the nozzles are maintenance-intensive. Overall, with the known window gluing machine, unclean and incomplete separations, detachments and unclean gluing occur in the case of short film sections. Uninterrupted operation is not possible and the operating costs are high.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Materialabläng- und - zuführvorrichtung sowie Fensterklebemaschinenach dem Oberbegriff des Anspruchs 1 bzw. 13 zu schaffen, die bei verbesserter Produktionsqualität und verringertem Wartungsaufwand kürzere Fensterlängen ermöglichen.The invention is therefore based on the object of creating a material cutting and feeding device and window gluing machine according to the preamble of
Diese Aufgabe wird entsprechend den Merkmalen der Ansprüche 1 bzw. 13 gelöst.This object is solved according to the features of
Hierdurch wird eine Materialabläng- und -zuführvorrichtung mit einem Ablängwerkzeug geschaffen, dessen Abstand zu einer materialabführenden Umlenkung eines Saugriemens geringer ist als zu einer materialzuführenden Umlenkung. Der Abstand zwischen Ablängwerkzeug und materialabführender Umlenkung kann weniger als 70mm, weniger 60mm, weniger als 50mm, oder 55mm +- 1mm, +-2mm, +-3mm oder +-5mm betragen. Er kann 2% bis 48%, bevorzugt 5% bis 40%, 10% bis 30% oder 10% bis 20% des Abstands zwischen materialabführender und materialzuführender Umlenkung betragen. Zweckmäßigerweise bemisst sich der Abstand entlang einer von der Ablängkante in Richtung auf die Umlenkung erstreckenden Tangente.This creates a material cutting and feeding device with a cutting tool whose distance from a material-removing deflection of a suction belt is less than from a material-supplying deflection. The distance between the cutting tool and the material-removing deflection can be less than 70mm, less than 60mm, less than 50mm, or 55mm +- 1mm, +-2mm, +-3mm or +-5mm. It can be 2% to 48%, preferably 5% to 40%, 10% to 30% or 10% to 20% of the distance between the material-removing and material-feeding deflection. The distance is expediently measured along a tangent extending from the cutting edge in the direction of the deflection.
Hierdurch können kürzere Materialabschnitte zuverlässig abgelängt werden. Bei Schrägstellung des Ablängwerkzeugs und insbesondere der Ablängkante entgegen der Vorschubrichtung sowie vorzugsweise auch quer zur Vorschubrichtung ergibt sich eine besonders zuverlässige und verbesserte Ablängwirkung. Dank Schrägstellung(en) der Ablängkante erfolgt eine Reißwirkung auf die Folienbahn mit schneidähnlicher Präzision. Erhöht wird die Zuverlässigkeit durch Abstreif- und/oder Andrückvorrichtungen mit konturierten und winkelverstellbaren Fingern, die in Aussparungen von Umlenkungen eingreifen können. Eine Beleimungsvorrichtung, die sowohl Klischee- als auch Düsenelemente aufweist, kann die kurz abgelängten Materialabschnitte zuverlässig und sauber mit Leim beaufschlagen. Es ergibt sich eine verbesserte Produktionsqualität bei verringertem Wartungsaufwand, so dass eine Fensterklebemaschine mit erfindungsgemäßer Beleimungs- und Materialabläng- und -zuführvorrichtung kürzere Fensterlängen in der Massenherstellung ermöglicht.As a result, shorter material sections can be reliably cut to length. When the cutting tool and in particular the cutting edge are positioned obliquely against the feed direction and preferably also transversely to the feed direction, a particularly reliable and improved cutting effect results. Thanks to the inclined position(s) of the cutting edge, there is a tearing effect on the film web with a precision similar to cutting. Reliability is increased by stripping and/or pressing devices with contoured and angle-adjustable fingers that can engage in recesses in deflections. A gluing device that has both cliché and nozzle elements can reliably and cleanly apply glue to the material sections that have been cut to length. The result is an improved production quality with reduced maintenance effort, so that a window gluing machine with a gluing and material cutting and feeding device according to the invention enables shorter window lengths in mass production.
