    • H01T19/00—Devices providing for corona discharge

Definitions

  • the invention relates to a device for adjusting the electrode contour, in particular in corona pretreatment devices, the rail-shaped electrode being formed from a series of movably mounted segments.
  • Such pretreatment devices are used for the surface treatment of films, containers or the like made of plastic, paper, wood, glass or metal.
  • corona treatment electrical discharges act on the surface of the material to be treated, which can then be printed, glued, coated or otherwise treated better.
  • a strong electric field is built up between an electrode and a roller or the like covered with a dielectric layer, over which the film or the body to be treated is passed.
  • the electrode In the case of corona treatment of plastic films, the electrode is constructed as a rail which extends across the film web.
  • the electrode When treating such foils and also other bodies, there is now the problem that only parts of the surface of the foil are to be treated and that the electrode must have a corresponding active contour for this purpose.
  • Another problem is the conversion of the pretreatment device to other films or a different position of the surface-treated areas on the film. To do this, the electrode must be converted with its active contour.
  • the rail-shaped electrode from a series of movably mounted segments which can be folded into a working position or into a rest position in which they are not electrically effective. By selectively turning over these segments, any active contour of the electrode can be formed (US-A-3397 136, Fig. 1).
  • the invention solves this problem with a device with the features in the characterizing part of the main claim.
  • the device according to the invention has the advantage that the pretreatment device no longer has to be switched off and opened during the conversion of the electrode.
  • the extruder and the film blowing device, as well as a subsequent winding device therefore do not have to be switched off.
  • the film can pass through the pre-treatment device and is only not treated.
  • the speed of the machine set-up device and the correspondingly short set-up time also have an advantageous effect.
  • a set-up device can also have a plurality of adjusting devices for one electrode, whereby the set-up time is further reduced.
  • the device according to the invention allows the individual segments to be positioned very securely, since the actuating device, by means of its retaining part, prevents the adjacent segments from being carried along by friction when positioning a segment.
  • the device according to the invention is particularly suitable for rail-shaped electrodes for film treatment. It can of course also be used in pre-treatment devices for cans or cups. It can also be used for any other rod-shaped or rail-shaped electrodes in other systems and devices.
  • the electrode segments are folded about a common axis.
  • the pivoting movement of the segments in the preferred embodiment has the advantage that it offers precisely defined positions for the rest and working position of the electrode segments.
  • the positioning of the segments is effected via a gearwheel-pairing between the actuating device and the segments. This has the advantage that the positioning movement of the individual segments can be controlled safely and precisely.
  • the actuating device remains in constant engagement with the segments even when passing over the row of segments.
  • This has the advantage in connection with the beveled teeth and the corresponding backlash that the row of segments is aligned when driving over from the adjusting device into the desired position.
  • the retaining part detects and aligns both the segments that are in the working position and the segments that are folded down in the rest position.
  • the constant engagement between segments and actuating device also has the advantage that the drive part of the actuating device does not have to perform idle strokes to position the segments. Overall, the set-up device according to the invention is thus distinguished by a high working speed.
  • the device according to the invention is also very small and compact, which is achieved primarily by the prismatic control shaft. This is also a guide for the actuator and drive for the pinion or drive part of the actuating device. This contributes to a compact design of the adjusting device, since the motor drives for the pinion movement and the lateral travel movement of the adjusting device are arranged outside the adjusting device.
  • the movable stop plate also contributes to an acceleration of the set-up time and a simplification of the control effort.
  • the entire row of segments folds into a defined position, preferably the working position. From this position, the individual segments that are not required are returned to the rest position by the actuating device.
  • the multi-stage clamping cylinder in cooperation with the slide rails between the individual segments, ensures optimal friction conditions during the various segment movements and holds the segment row elastically after the conversion. Due to the frictional engagement between the segments, however, it is still possible for individual segments to evade in special situations during operation, for example in the event of a possible film thickening.
  • the device according to the invention can be controlled by hand. In the interest of a high set-up speed in connection with great ease of use, the set-up device can also be provided with a freely programmable control.
  • FIG. 1 and 2 show a pretreatment device 1 for the surface treatment of plastic films or the like.
  • the film 27 is guided over a plurality of deflection rollers and over a treatment roller 25. In other embodiments, several such treatment rollers can also be provided.
  • the treatment roller is covered with a dielectric layer and connected to a generator, not shown, which supplies high-frequency alternating current.
  • a strong electric field is built up between the treatment roller 25 and one or more electrodes, each consisting of a row of electrode segments 3. In this field, electrical discharges act on the surface of the film 27 and prepare it for subsequent treatment.
  • the surface treatment of the film 27 should now not be carried out over the entire width, but only in partial areas.
  • the segments 3 are brought into a working position according to FIG. 1 at the corresponding locations, while the segments that are not required are folded down onto a stop plate 10 at the locations where no surface treatment is to take place. In this position, the folded segments 3 are not electrically effective.
  • the electrode segments 3 are pivotably arranged on a common axis 5.
  • the segments are spaced from each other by sliding disks 6 made of Teflon, which are also arranged on the axis 5.
  • the sliding disc provides electrical insulation of the segments and thereby prevents a possible misdirection of the current.
  • the segments are prevented from sticking together by means of tape products.
  • This device 2 contains an adjusting device 13, which in detail consists of a pinion 16 and a retaining part 17.
  • the adjusting device 13 is guided in a longitudinally displaceable manner on a control shaft 15 with a prismatic, in particular square, cross section.
  • the control shaft 15 is arranged at a distance above and parallel to the axis 5 of the electrode segments 3, so that the adjusting device can be moved parallel to the electrode.
  • the travel drive takes place via a chain drive 24 which runs parallel to the control shaft 15 and is driven by a stepper motor.
  • the adjusting device 13 is connected to the chain via an extension 23.
  • the actuating device can be moved relative to the row of segments via the chain drive and the stepping motor and can be positioned exactly behind each individual segment 3 in the manner shown in FIG.
  • a ball screw or the like can also be used instead of the chain drive.
  • Each of the segments 3 carries on its top a dental arch 4, the center of which lies in the middle of the axis 5.
  • the dental arches 4 interact with the pinion 16 and locking lugs 20, 21 cm retaining part 17 of the adjusting device 13.
  • the respective segment 3 is then folded about the axis 5, while the locking lugs 20, 21 are in engagement with the dental arches 4 of the adjacent segments and hold them in place in the meantime.
  • the locking lug 21 holds the segments 3 in the working position, while the locking lug 20 holds the segments 3 folded down in the rest position on an inclined stop plate 10.
  • the locking lugs 20, 21 are so wide that, as shown in Fig. 2, they are in engagement with several segments.
  • the width of the pinion 16 is preferably chosen so that it is in engagement with only one segment.
  • the pinion 16 must be able to rotate within the adjusting device 13, the retaining part 17 having to stand still at the same time. This is due to a special design of the control shaft 15 and Adjusting device 13 achieved.
  • the retaining part 17 is divided into two halves of equal size, between which the pinion 16 is arranged. The two halves of the retaining part 17 are connected to one another by screws.
  • the pinion 16 is rotatably guided directly on the prismatic control shaft 15, but longitudinally displaceable.
  • the control shaft 15 is connected to an actuator, not shown, so that rotation of the control shaft 15 causes rotation of the pinion 16.
  • the two halves of the retaining part 17 are each rotatably arranged on a sleeve 18.
  • the two sleeves 18 are then rotatably guided on the prismatic control shaft 15, but longitudinally displaceable.
  • a U-shaped guide bracket 22 which is open at the bottom is fastened to the retaining part 17 (cf. his two legs on two vertical walls of the housing 14 of the device 2 is guided positively, but longitudinally. The result of this is that when the control shaft 15 rotates, the sleeves 18 also rotate, but the retaining part 17, however, is held non-rotatably and can therefore perform its locking function.
  • the adjusting device 13 is always in engagement with a plurality of segments 3. This engagement is retained even when the adjusting device 13 is moved laterally on the control shaft 15. This is used to align the driven segments 3 over the teeth of the pinion 16 and the locking lugs 20, 21 when the adjusting device 13 is moved. For this purpose, a certain backlash is provided and the teeth of the dental arches 4, as well as the locking lugs 20, 21 and the teeth of the pinion 16 are chamfered on the side.
  • the segments 3 should assume defined, stable positions in the working and rest position. In the rest position, they rest on the stop plate 10 which is continuous along the axis 5 and are held there by their own weight. In the erected working position, they are clamped in accordance with the exemplary embodiment in FIG. 1 by a curved leaf spring 12 running along the axis 5. For this purpose, the segments 3 have an extension 26 on their underside which slides over the leaf spring 12 when the segments 3 are raised and is then pressed by the latter against a stationary stop.
  • Figure 2 shows a further embodiment.
  • the segments 3 are spaced apart from a fixed stop via a spring assembly 7.
  • a multi-stage clamping cylinder 8 is arranged, which presses with a suitably designed piston via the end bearing of the axis 5 onto the next segment 3.
  • the clamping cylinder 8 has three operating levels. In the unloaded state, it does not exert any pressure on the row of segments 3. In the semi-loaded state, it exerts a relatively low pressure on the outermost segment 3, which propagates from segment to segment to the spring assembly 7 and the stationary stop via the sliding disks 6.
  • the clamping pressure is relatively light here, so that the segments can be moved against each other.
  • the clamping cylinder 8 In the third operating position, the clamping cylinder 8 is fully loaded and exerts a full clamping pressure on the segment row, which holds the segments in their set position during the operation of the pretreatment device.
  • the segments can also avoid film thickening or the like.
  • the segments 3 can in principle be repositioned by the adjusting device 13 from any position during the changeover. For the fastest possible retrofitting, it is advisable to first bring all segments into a common position and from there fold over individual segments according to the desired electrode contour.
  • the oblique stop plate 10 is attached to a driven shaft 11.
  • the shaft 11 is rotated via an actuating cylinder and a deflection gear and, via the stop plate 10, folds all the segments 3 placed thereon in the rest position into the upright working position.
  • the adjusting device 13 has moved into a zero position out of engagement with the segments 3 (cf. FIG. 2).
  • the control shaft 15 is correspondingly extended at one or both ends with respect to the outermost segments 3.
  • clamping cylinder 8 is half-loaded and the actuating device 13 is moved over the row of segments and positioned over the segments to be folded down into the rest position in accordance with the desired electrode contour.
  • the axis 5 is supported by one or more intermediate bearings 9, which are longitudinally displaceable relative to the housing.
  • the intermediate bearings 9 dodge and thus allow the clamping pressure to propagate over the entire row of segments.
  • one or more stationary intermediate bearings are provided, in which the axis 5 is guided in a longitudinally displaceable manner.
  • the clamping cylinder 8 is fixed on the axis 5 and the axis 5 is in turn in the repository on the guided on the other side.
  • the clamping cylinder 8 is supported via the segments 3 at the nearest intermediate storage and pulls the axis 5 through the intermediate storage or storage.
  • the spring assembly which is supported by an extension on axis 5, is carried along and braced against the segments.
  • clamping rings with disc springs are provided on the axis, which press on the segments when the axis is tightened and brace them against the nearest stationary intermediate bearing.
  • the clamping pressure can be distributed evenly on the one hand and thermal expansion can be easily compensated for on the other.
  • the drives for the control shaft 15, the adjusting device 13, the shaft 11 and the clamping cylinder 8 are interconnected in an automatic control and connected to a freely programmable computer. Recurring electrode contours can be saved in the computer or typed in by hand and the set-up device automatically sets the desired contour.
  • the device 2 is accommodated according to FIG. 1 in a compact housing 14 and can be exchanged as a complete part.
  • the segments are positioned in a sliding movement instead of a folding movement. Instead of a dental arch, these segments are then equipped with a toothed rack and provided with a straight guide.
  • the segments can also be conveyed from the working position to the rest position and back in other ways, for example by means of an actuating cylinder.
  • FIG. 3 shows a further variant of the actuating device 13 in a schematic cross section analogous to FIG. 1.
  • the segments -3 are provided with a friction arch 31 instead of a dental arch and rotate in the manner described above about an axis 5 from a working position into a Rest position (shown in dashed lines).
  • These positions are defined by stops 10, one of which is pivotally mounted and driven according to FIGS. 1 and 2 via an axis 11.
  • the positioning of the segments 3 takes place via a friction drive, the drive part 16 including a friction wheel 28 which is profiled on the circumference.
  • the friction wheel 28 has two cam parts 30 of the same size and evenly distributed over the circumference, which correspond to the normal friction wheel contour. Flattenings 29 are arranged between the cam parts 30.
  • the friction wheel 28 is connected to the control shaft 15 in a rotationally locking manner and can be displaced in the longitudinal direction thereon analogously to the exemplary embodiments in FIGS. 1 and 2.
  • the retaining part 17 consists of two cam disks 32 profiled corresponding to the friction wheel 28, which are arranged on both sides of the friction wheel 28 in a rotationally locking and longitudinally displaceable manner on the control shaft 15.
  • the cam disks 32 act on two clamping jaws 33, which are also arranged laterally from the friction wheel 28 and are guided radially in a guide 35 with respect to the friction arch 31 and are held in contact with the cam disk 32 by springs 34.
  • Fig. 3 shows the overtravel position of the actuating device 13, in which the drive part 16 and the retaining part 17 can be moved along the row of segments 3 without engagement with the latter.
  • the flats 29 face the flattened portions 29.
  • the device for achieving the longitudinal movement of the adjusting device 13 is the same as in FIGS. 1 and 2.
  • the friction wheel 28 is rotated via the control shaft 15, as a result of which the cam part 30 comes into engagement with the friction arch 31 of the respective segment 3.
  • the path of the cam part 30, which has a circular circumference is shown in dashed lines.
  • the friction wheel 28 can therefore also have more cam parts 30 and flats 29.
  • the sheet length is such that it overlaps the connecting line between the axes 15 and 5 in both positions.
  • the friction wheel 28 can thus be brought into frictional engagement with the friction arch 31 by means of a predetermined rotational movement of the control shaft 15 and position the segment 3 in both directions. After each rotational movement, the friction wheel 28 then comes out of engagement with the friction bow 31.
  • the adjacent segments 3 are assigned to clamping jaws 33, which are pressed by the cam disk 32 against the friction arches 31 to be locked when the control shaft 15 rotates. Since this locking should take place at the same time as the positioning movement of the desired segment 3, the cam disk 32 has the same profile as the friction wheel 28. However, the arc of the cam part 36 of the cam disk 32 is selected somewhat larger in proportion, so that the clamping jaws 33 are pressed on before the friction wheel 28 with its cam part 30 comes into engagement with the friction sheet 31 to be positioned.
  • the clamping jaws 33 After completion of the positioning movement, the clamping jaws 33 again face the flattening on the cam disk 32, so that the clamping jaws 33 along the guide 35 under the action of the springs 34 again from the Lift off friction sheets 31.
  • Variations of the above-described friction drive of the actuating movement 13 are possible in that the friction wheel 28 is designed as a full wheel and that the control shaft 15 is movably mounted. The friction wheel 28 can then be moved without engagement with the friction arches 31 and is first brought into engagement with the friction arches 31 by a feed movement of the control shaft 15.
