Definitions
- the invention relates to a guide element for a film tube produced in the blown film extrusion process, comprising a support structure with guide means attached to the support structure, which act on the circumference of the film tube.
- the melt produced by at least one extruder thermoplastic material is extruded from an annular outlet opening of a tool and inflated to form a tube, which is subsequently from a so-called flattening device to a double-film web collapsed, passed between squeezing rollers and subsequently fed to a take-up device.
- the flattening device consists in the simplest case of two arranged on diametrically opposite regions of the film tube and at an acute angle - in the manner of an inverted V or A - asked each other flat lay elements whose distance from one another in the exit direction of the film tube is considered steadily reduced.
- the flattening elements carry a multiplicity of guide means acting on the circumference of the film tube, such as bars, rollers or brushes, so that the initially cyclic iindharide film tube is gradually laid over an oval shape with continuously changing diameters to a double-layered and folded at the longitudinal edges of the film.
- the film tube also laterally, i. in the areas not guided by the flattening elements, defined to lead.
- the brushes, rollers or strips used as guide means for the film tube only an insufficient point contact is possible.
- the film easily throws folds which run through to the finished roll and reduce the quality, which appears to be in need of improvement.
- the invention proposes guide elements whose support structure comprises a plurality of support legs which are connected to one another in an articulated manner and which are adjustably supported relative to one another by means of adjusting drives and at least one guide means for the film tube is attached to each support leg.
- Such guide elements can be used both as flattening and lateral guiding elements.
- the guide elements according to the invention have various adjustment options and can be adapted individually to the circumferential course of the flat tube passing through the film tube.
- the guide elements proposed according to the invention make it possible to use the lateral guide element in a lateral guide device with two lateral guiding elements arranged on diametrically opposite regions of the film tube between the flat laying elements, each of which is formed from a guide element according to the invention.
- a flattening device proposed in the context of the invention therefore comprises two flattening elements arranged at diametrically opposite regions of the film tube and adjustable at an acute angle for transferring the initially circular cross section of the film tube over oval cross sections to a double lying film web and between the flattening elements the side tube associated with the film guide elements for the recessed by the Flachlege- areas of the film tube.
- each support leg of the guide element according to the invention has its own adjustment drive in order to achieve the most flexible possible adjustments.
- the guide means may be fixed by means of at least one support arm rigid or hinged to the support legs.
- the guide means themselves can be, but also be rollers or cylinders from a suitable plastic material such as CFK 1 silicon or aluminum, and also brush rollers may be provided, or else panels are provided, from which a stream of air for generating an air cushion between the plate and the film tube exits to ensure a non-contact leadership.
- Such plates are preferably provided with a microporous surface for producing a homogeneous air cushion. Under microporous here is an average pore diameter between 5 to 100 microns understood. In the case of rotating rollers or rollers is preferred to pay attention to a particularly easy run.
- the support structure of the guide element according to the invention consists of several articulated support legs, which can be adjusted individually by means of suitable adjustment drives according to the desired course of the film tube during the passage through the flattening device.
- one or more support arms for holding guide means may be attached to each support leg.
- Per support leg at least one support arm is provided.
- guide means are pivotally mounted on the support arms about a pivot axis extending in the exit direction of the film tube.
- the adjustment of the hinged interconnected and segmentally one another continuing support legs can be made variable due to the separately provided for the support legs adjustment drives with respect to the included between adjacent support legs angle to make an adjustment to the changing cross section of the film tube.
- it may also be provided, for example, to design the individual support legs with a suitable telescoping mechanism so as to be longitudinally adjustable, which offers additional degrees of freedom for adaptation to the desired contour of the film tube to be laid flat.
- an adjustment transverse to the longitudinal extent of Support legs provided to make an adjustment to different diameters of the film tube can.
- the guide element according to the invention with a plurality of support legs, e.g. at least three support legs, and also arcuate desired contours of the film tube can be simulated with high approximation, especially if also attached to the individual support legs support arms and attached holding forks for the guide in turn adjustable, for example, height adjustable, side adjustable and adjustable angle are running.
- each guide element may be formed at the upper end portion of the support structure with a guide vane, which comes when using the guide element according to the invention in a Thisrak- tion device near the squeezing rollers of the extrusion device comes to rest and forming during flattening longitudinal edge of the flattened film tube engages on the outside, the forming edge fold leads directly into the nip between the squeezing rollers and thus ensures an exact formation of the edge fold of the flattened film tube.
- This vane may also be made of suitable plastics or e.g. be made of aluminum, if it is in contact with the film tube or even with the film tube facing porous, preferably microporous surface for the outlet of a supplied air flow and for generating an air cushion for non-contact guidance of the film tube to be equipped.
- a microporous surface is understood to mean one having an average pore size of between 5 and 100 ⁇ m.
- the distance of the guide vanes to subsequent squeezing rollers should be selected to be low and is preferably adjustable, so that preferably a defined guidance of the longitudinal edge of the film tube can be brought into the nip of the squeezing rollers.
- the adjustment of the individual support legs can be accomplished for example via spindle drives or other suitable drives with high positioning accuracy, more preferably each support leg has its own adjustment.
- the adjusting drives in turn can also be connected to each other centrally.
- FIG 1 shows the schematic side view of an inventively designed guide element.
- FIG. 2 shows the cross-sectional configuration of the film tube which changes during the flattening of the film tube
- Fig. 3 is a plan view of a part of an inventively designed guide element.
- FIG. 1 shows, in a roughly schematic representation, a film tube 1 produced from an extrusion device in a known manner and guided vertically upwards in an exit direction A, which is gradually joined together to form a flat film tube by means of flattening elements of a flattening device which are not illustrated. It further recognizes a belonging to the flattening side guide device with a side guide element 2, which is of course arranged mirror-image to the central longitudinal axis of the film tube 1 on the opposite side thereof.
- the film tube 1 is gradually transferred via oval cross sections, which are exemplified by Q2 and Q3, into a flattened, double-layered film web with a cross-section Q4 and edge fold 10, in which the film tube 1 has a circular cross-section Q1.
- the side guide members 2 continuously guide the film tube 1 in the region 400 of larger diameter during this plane from the cross section Q1 to the cross section Q4, i. between the flattening elements according to reference numeral 300.
- Each side guide element 2 consists according to Figure 1 of a support structure with three reference numerals 20, 21, 22 supporting legs, which are connected to each other via joints 23, 24, i. are concatenated.
- Each of the support legs 20, 21, 22 in turn carries support arms 25 on which the film tube 1 facing guide means 27 are supported for the film tube 1, for example CFRP rollers, which are in shallow contact with the film tube 1 and an exact guide thereof in the desired Effect contour.
- guide means 27 may be provided in pairs at the free end of each support arm 25, which are mounted as required via a pivot axis S extending in the direction of advance of the film tube 1 in order to adapt optimally to the circumference of the film tube 1.
- a guide shell 27a is provided instead of guide means in the form of rollers, which overlaps the forming edge fold 10 of the flattened film tube 1 outside and for an exact guidance of the same into the gap between the congruent in Figure 1 successively arranged squeezing rollers 5 ensures.
- independent drives for example spindle drives 28 are provided which, in the exemplary embodiment shown, engage the support leg 20 or support leg 22, while the support leg 21 located therebetween has a cantilever arm 29 on which the drives 28 engage.
- a separate drive 28 may be provided for each support leg 20, 21, 22 without connecting these drives with each other.
- the support legs 20, 21, 22 are independently adjustable in the direction of the diameter D of the film tube and can also be telescoped in the direction of arrow T, i. be formed variable in length, so that their axial length is adjustable or adjustable.
- each support leg at least one support arm 25 for a guide means having.
- the guide elements according to the invention can be used not only as a side guide element 2, but also as a flattening element of the flattening device.
