Definitions
- the invention relates to a device for setting up a plastic profile in the extrusion of plastic profiles with the features of claim 1 and a method for setting up a plastic profile in the extrusion of plastic profiles with the features of claim 15.
- Plastic profiles made of PVC and other materials are often produced by extrusion.
- a substantially homogeneous plastic melt is prepared and brought to a pressure of about 200 to 400 bar and to a temperature of about 190 ° C.
- the plastic melt is pressed at high pressure through an extrusion die.
- the plastic melt has approximately the contour of the desired plastic profile at the outlet of the extrusion die.
- the melt strand undergoes a calibration in order to be cooled in this while maintaining the profile contour.
- Calibration devices for the production of comparatively complicated plastic profiles such as e.g. Window profiles, typically have a dry calibration area and a subsequent wet calibration area.
- the dry calibration has at least one calibrator block.
- the still soft plastic of the extruded plastic profile is sucked by means of an applied negative pressure to the profile close wall.
- the heat passes from the plastic profile into the calibration device.
- the cooling of the calibration device is performed by cold water, which is guided by cooling channels in the vicinity of the walls.
- the wet calibration usually has at least one vacuum tank, with several vacuum tanks arranged one behind the other. In the vacuum tanks, cooling water has direct contact with the extruded plastic profile. Since the plastic profile on entry into the wet calibration is still deformable, calibration or other, simplified Kalibratorblöcke are still within the at least one vacuum tank arranged to support the plastic profile to cool and achieve a dimensionally stable state and to keep in shape. If the plastic profile inside cooled to about 30 to 50 ° C, is usually a dimensionally stable state and there is no further support and cooling in a vacuum tank required.
- the plastic profile passes after the wet calibration in a profile trigger and then to a cross-cut saw.
- the cut-to-length plastic profiles cool to room temperature in the air and are stored in pallets until further processing.
- the entire extrusion device i. the extruding line, which covers all processes from setting up the extrusion die and calibrating, preheating the extruder, driving the extruder screws to achieving the desired throughput, retracting the plastic profile so that the melt strand passes from the extrusion die within the calibration and is captured by the caterpillar take-off is, the setting up of the plastic profile, so that the hollow chambers are formed, etc. includes until the plastic profile has the desired geometry.
- the invention relates to a device and a method for setting up the profile in the caterpillar take-off.
- the comparatively complex process for setting up the profile is to be simplified.
- a profile guide panel as part of the profile guide device and / or the profile guide device itself against displacement in the extrusion direction in front of an inlet region in the caterpillar take-off spatially fixed and displaced in height and / or side position and fixable and rotatable about the extrusion direction and / or fixable.
- the profile guide panel have an opening which is adapted to the outer contour of the plastic profile, wherein substantially the contour of the opening with respect to the contour of the plastic profile is spaced by an offset.
- the plastic profile thus has some play in the opening.
- the offset can be e.g. 1 to 2 mm.
- an inlet slope is arranged in one embodiment at the opening of the profile guide panel. This can e.g. have a length of 8 to 20 mm and / or an angle of 10 to 30 degrees with respect to the extrusion axis.
- the operation of the profile guide aperture is facilitated if, in one embodiment, it is designed in several parts, in particular in two parts. Thus, this can be placed on the continuous profile strand and also removed.
- the parts of the profile guide panel can be connected to one another in a form-fitting manner, in particular via at least one dovetail connection and / or at least via a tongue and groove.
- the opening in one embodiment in the groove area, is generously released or the grooves remain unconsidered by the guide contour of the opening does not protrude into the grooves of the plastic profile.
- the profile guide panel is received by a holding device, which allows the required linear and / or rotational degrees of freedom and prevents further degrees of freedom. So for example, the profile guide panel can only be rotated or moved in a plane that is perpendicular to the extrusion direction.
- the profile guide screen can be designed to be rotatable, the angular position in particular by a locking device, in particular a latch device, discreet, i. in stages, is fixable.
- the Flaltvortechnischigan for the profile guide panel is mounted vertically displaceable and fixable and mounted on a fixedly attached to the caterpillar track mounting rail horizontally, transversely to the extrusion direction, displaceable and fixable.
- At least one insert made of wear-resistant material may be arranged on heavily stressed areas of the profile guide panel.

- the embodiments described here relate to the profile guide device for setting up a plastic profile 1 in the course of the starting process of an extrusion plant, which is basically illustrated in FIG.
- the melt When approaching the extrusion line, the melt initially exits the extrusion die 2 without a specific contour and flows viscous onto the ground. Then the melt, i. H. the future profile strand, detected after exiting the extrusion die 2 with a cord loop and pulled with an auxiliary profile through the entire calibration 3, wherein the strand is cooled continuously. Only when the profile strand has reached a caterpillar take-off 4 and thus allows the acquisition of larger withdrawal forces, the so-called setting up of the plastic profile begins. 1
- the dry calibrations are pressurized and then the flooding chambers of the plastic profile are pierced at the nozzle exit. As soon as air can enter the flea chambers, they gradually form. Only when occasionally the hollow chambers have overcome the entire calibration 3 including the area of the caterpillar take-off 4 and have after cutting the strand in the saw at the cutting surface open cross sections, penetrates contrary to the extrusion direction E sufficient air into the hollow chambers and the plastic profile 1 forms gradually the outer contour. From this point on, the plastic profile 1 leaves the calibration 3 with a cross section corresponding approximately to the nominal cross section, but this is largely destroyed again by the contact pressure in the caterpillar take-off 4, that is, the plastic profile is compressed and often rotated in a certain direction about the longitudinal axis ,
- the operator is forced to briefly exert a counter rotation on the plastic profile 1 in the short area between the end of the calibration 3 and the caterpullar 4, where makeshift screw clamps and wooden strips are used and occasionally the Safety tunnel is opened with regard to intervention protection.
- profiling in a conventional manner requires interaction between multiple operators and a particular skill.
- the aim of the embodiments is the simplification of Profilaufs negligences with particular attention to the safety aspects.
- Fig. 2 the two beads 5, 6 of the caterpillar take-off 4 are shown, which deduct the plastic profile 1 in the extrusion direction E from right to left.
- an engagement protection 7 is arranged, which is an important safety device, which prevents operators with the hands can reach into the effective range of the caterpillars.
- the profile guiding device 10 is arranged. This is here fixed to the caterpillar 4.
- a mounting rail 16 is mounted, which supports the holding device 12 for the profile guide diaphragm 12 (see FIG. 3).
- Fig. 2 the entire profile guide device 10 is shown in an overview in a side view, which receives a profile guide panel 13, which is the central element of the device.
- the profile guide panel 13 is thus upstream upstream of the safety tunnel of the caterpillar take-off 4 against accidental intervention in the caterpillar area, see the caterpillars 5 and 6, fixed in the extrusion direction E, but laterally and / or vertically displaceable and rotatable about the extrusion axis E arranged , As a result, details of the profile guiding device 10 are shown.
- the profile guide device 10 with the exception of the profile guide panel 13 may be part of the caterpillar take-off 4 and may be used for different plastic profiles 1, that is, for different profile guide panels 13.
- Fig. 3 shows a profile guide device 10, consisting of a support rail 16, a receiving plate 21 and a holding device 12 for the profile guide panel 13.
- the support rail 16 is mounted in front of the Eingreifschutz 7 to the caterpillar 4.
- a mounting plate 21 is mounted for the holding device 12, which is displaceable and fixable in the transverse direction (double arrow).
- the holding device 12 is designed as a vertically displaceable and fixable receiving ring for the profile guide panel 13 (not shown in Fig. 3).
- a receiving plate 21 is shown together with a Flaltevorraum 12 and a profile guide panel 13 in an oblique view against the extrusion direction E. It can be seen that the angular adjustment can be carried out with the aid of a fleece 14.
- a locking device 15, designed here as a latch device, provides for a possibility of fixing the angular position.
- the movement of the Flebels 14 can be made by an operator or by a control device, not shown here.
- the folding device 12 is mounted vertically displaceable and / or fixable in the receiving plate 21.
- the pawl and the teeth in the profile guide panel 13 are designed so that several angular positions are covered starting from the expected starting position over several intermediate stages to the final position with correctly positioned plastic profile 1 and during Aufsutzs a tilting back of the plastic profile 1 is prevented in the starting position , When the latch is lifted, all angular positions can be adjusted manually.
- the pawl can be used for both erection directions by being latched either on the operating side of the extrusion line or on the opposite side as shown.
- FIG. 5 an embodiment of a profile guide panel 13 is shown.
- a two- or multi-part design (lower part 13 ', upper part 13 ") is preferable to be able to put the profile guide panel 13 even after the threading of the plastic profile 1 and to be able to remove them after successfully setting up the plastic profile 1 ,
- the items 13 ', 13 “have in the parting surfaces a Flaltesystem with spring 17 and groove 18, which cooperate similar to a dovetail guide.
- the two parts 13 ', 13 are guided around the initially non-deformed compressed plastic profile 1 (not shown here) and assembled by telescoping in the extrusion direction E loosely and inserted into the folder 12. After the two parts 13 ', 13 "with the molded collar on Resting receiving ring of the holding device 12, they are sufficiently connected to each other in order to effect the rotation of the plastic profile during the erection can.
- the profile guide panel 10 can be made of any metals, but it is also a plastic version possible. In the latter case, a 3D printing method is advantageous because it can be manufactured at low cost comparatively complicated components.
- the Flebel 14 for the angular adjustment in one piece to a part of the profile guide panel 13 "be molded with.
- the strength of the 3D printing process is sufficiently high and the dimensional accuracy is accurate enough to meet the requirements for setting up the profile during harsh environmental conditions in an extrusion operation over several years.
- inlet slopes 1 1 are arranged on the circumference.
- Fig. 6 the profile guide panel 13 is shown in FIG. 5 with the performed in an opening 19 plastic profile 1 (here a sash profile) with view in the extrusion direction E.
- the plastic profile 1 is fully formed.
- the contour of the opening 19 in the profile guide panel 13 must correlate only a few striking surfaces or outside corners with that of the plastic profile 1, on the one hand to allow the twisting of the plastic profile 1 when setting up with moderate effort and on the other hand a lingering of the plastic profile with coarser contour deviations during to avoid the starting and Aufstellvorganges.
- This profile guide panel 13 has in comparison to the cooling panels of the calibration 3 larger exemptions, with only the striking outer contour of the plastic profile 1 is taken into account and in particular groove portions 20 of the plastic profile 1 are not shown. All around the plastic profile 1 1 mm wide gap is left free, and in the case of grooves of the plastic profile 1, the contour of the opening 19 of the groove contour does not follow.
- the inlet slope 1 1 can be seen. This causes the plastic profile 1 does not get stuck during the Profilaufs negligences the occurrence of projecting from the plastic profile 1, irregularly shaped profile segments and as a result breaks off or the profile guide panel 13 is damaged.
- the inlet slopes 1 1 can sometimes have a certain twist, that is, in some cases longer and deeper running. Some with respect to a horizontal plane clearly asymmetrical plastic profiles 1, such. Wing profiles for a flush design in the case of window profiles, tilt in the crawler inlet area for tilting by approximately 90 ° in a preferred direction (to the left or right), the inlet slopes are designed here so that they act against this preferred tilting direction.
- Fig. 7 shows an embodiment of a two-part profile guide panel 13 ', 13 ".
- the view is in the extrusion direction E.
- this serves for setting up a "wing profile", which is the basis of all Fig.
- the illustrated orientation corresponds to the initial orientation of the profile guide panel 13 before the start of the installation process.
- the profile guide panel 13 is now fixed in the orientation which is to be expected when the plastic profile 1 gradually forms its flohl chambers.
- this orientation corresponds to the orientation according to FIG. 7.
- the plastic profile 1 In the course of the gradual formation of the profile shape after piercing the Flohlhuntn takes the plastic profile 1 in many cases "automatically" the intended location, ie the plastic profile 1 runs with more or less formed hollow chambers and in a twisted angular position through the Caterpillar trigger 4 and previously through the profile guide panel 13. If not, then the profile guide panel 13 of Fland is rotated until it matches the (twisted) position of the plastic profile 1. Once the contour of the plastic profile 1 is almost completely formed and the wall thicknesses are already close to the desired thickness, the plastic profile 1 by relieving the contact pressure of the beads 5, 6 and rotating the profile guide panel 13 in the end orientation of FIG. 6 during the running extrusion are completely set up.
- the starting process is completed and the extrusion line can start normal production operation.
- the inlet-side contact force is set much smaller than the outlet-side contact pressure.
- the plastic profile 1 then runs in the correct position and without being crushed by the caterpillar take-off 4. In many cases, it is even to be expected that the plastic profile 1 will set up by itself if the starting position of the profile Guide plate 13 has been selected correctly at the beginning and only the contact pressure of the beads is briefly reduced and then adjusted to the setpoint.
- the delicate process of Profilaufsutzs in caterpillar take-off 3 can be performed with embodiments of the device without handling in the danger zone near the caterpillar. The time required is significantly lower. Thereafter, the fine adjustment of the profile geometry can be carried out in the usual way.
- Come caterpillars 3 are used, in which the upper bead is mounted oscillating about a horizontal, transverse axis and the contact pressure is applied by lowering this axis, the contact pressure in the catchment area of the caterpillars can not be set separately.
- the transverse axis is slightly offset from the center position of the track carrier in the extrusion direction, so that the force component of the contact force in the inlet area is smaller than that in the outlet area.
- the total contact pressure when setting up the plastic profile 1 is gradually reduced until the crushing of the profile is suppressed, which is supported by the slightly offset to the rear point of application of the contact pressure.
- the axis with a carriage obliquely against the direction of extrusion by about 30 ° be made flat sloping deliverable, whereby the withdrawal force has a vertical component, which is used as a contact force.
- a self-locking design can be selected, is always deducted with minimal contact pressure and in the case of fluctuations in the withdrawal force and the contact pressure is "automatically” changed.
- the plastic profile 1 in the caterpillar take-off 3 almost always arises "by itself", since it can be pulled off "automatically with minimal contact pressure” without the risk of the plastic profile slipping, as a result of which the crushing of the profile is stopped in the simplest manner.
- an insert made of wear-resistant material 22 is arranged in the left region, here on a heavily stressed region of the profile guide panel 13.
- the insert 22 is connected via a groove to the lower part of the profile guide panel 13 ".
