Definitions
- the invention relates to a contact roller system of a winding machine with several Face to face side by side freely rotatable roller segments and a winding machine for winding a running web, in particular one Paper web or plastic film that contains the contact roller system.
- winding machine can be divided with the winding machine by longitudinal cuts Winding reels wound up, which are held while winding with aligned sleeves then the contact rollers for each winding roll must be individually movable, to compensate for unavoidable differences in diameter of the winding rolls.
- the axial length of a contact roller must be equal to or greater than the width of the Winding roll against which it is pressed.
- the invention has for its object a generic contact roller system to improve so that the gap between two adjacent roller segments for Avoidance of markings can be kept as low as possible.
- each roller segment is in its position and its contact pressure individually adjustable.
- Narrow roller segments can be used arrange so close to each other with individual pressure mechanism and control that they share the function of a contact roller with one of the winding roll width appropriate length.
- the Computer-controlled contact rollers automatically change the width of the winding rolls be adjusted.
- the gap between two adjacent roller segments can be due to the arrangement of the bearing plates keep one another extremely low to avoid ring marks when winding to avoid the winding rolls.
- the contact roller system is part of a winding machine for winding of moving webs 1, in particular paper webs or plastic films.
- the material webs 1 divided by longitudinal cuts are wound up into winding rolls 2, which are held in the winding machine with aligned sleeves; either the winding rolls 2 are wound on a common winding axis or each Winding roll 2 is held by two retractable clamping heads in its sleeve.
- Contact rollers are required especially at high winding speeds, to largely prevent air from entering the winding rollers 2.
- the contact roller system contains a row from side to side side by side arranged roller segments 3, whose axial length is less than that Minimum width of a winding roll to be wound 2. In the embodiment the length is 200 mm to 300 mm.
- Each roller segment 3 is one across the working width of the winding machine extending crossbar 4 individually Movable perpendicular to its axis of rotation 11 and thus against a winding roll 2 pressed on so that unavoidable differences in diameter of the winding rolls 2 can be compensated.
- each roller segment 3 on its end faces on two side bearing plates 5 free rotatably mounted, which extend parallel to the end face of the roller segment 3 and are attached to a carriage 6.
- the two bearing plates 5 of a roller segment 3 are each on the side facing away from the contact point to the winding roll 2 by means of a cross plate 25 connected to a rigid frame.
- Each carriage 6 is on the crossbar 4 in a linear guide 8, preferably a ball guide, to the winding roll 2 and back away from this, so perpendicular to the axis of rotation 11, slidably mounted.
- a pneumatic piston-cylinder unit 7 is used for the displacement movement on the one hand on a support plate 9 fastened on the crossbar 4, on the other hand the fork-shaped bearing part 10 of the carriage 6 is attached to which the cross plate 25 of the frame of a roller segment 3 is suspended.
- the sled 6 are designed narrower than a roller segment 3, so that a for each roller segment 3 Carriage 6 can be arranged on the crossbar 4.
- the side bearing plates 5 of two adjacent roller segments 3rd alternately arranged below or above the axis of rotation 11. This enables the two necessary bearing plates 5 between two roller segments 3 to be arranged one above the other perpendicular to the direction of displacement of the slide 6, as shown in Figure 1. There is the position of the side bearing plate 5 'of adjacent roller segment 3 'shown.
- FIGS. 4 and 5 The structure of a lateral bearing plate 5 is perspective in FIGS. 4 and 5 shown.
- the bearing plates 5 are preferably constructed identically so that they both for installation above the axis of rotation 11 ( Figure 4), as well as for the construction below the axis of rotation 11 (FIG. 5):
- Each bearing plate 5 consists of a plate-shaped part 12, in one of which Longitudinal edge a semi-circular cross-section 13 is incorporated for later mounting of the head of a fastening screw 22.
- On one side is on the part 12 a disc-shaped axle support 14 with a central through hole 15 attached, for example soldered flat, or with the plate-shaped part) 12 worked from a piece 5, 5 '.
- the central through hole 15 is aligned the groove 13.
- Concentric around the axle beam 14 is in the inside of part 12 Ring groove 16 incorporated, the curvature and extent is selected so that the appropriately designed end of a roller segment 3 without contact in the annular groove 16 can rotate.
- the back wall 17 of part 12 remaining at the bottom of the groove 16 is designed to be extremely thin as it has the minimum distance between two neighboring ones Roll segments 3 defines.
- the thickness of the back wall 17 is preferably 1 mm Or less. Despite the small thickness, the required strength has to be borne given a roller segment 3, since the part 12 is made thicker in the remaining area and the annular back wall 17 does not have a straight bending line.
- an appropriate Bevel of the parts 12 on the side facing a winding roll 2 can Wrap angle of the web 1 around a roller segment 3 regardless of the installation up or down and from the winding direction in the desired area can be set symmetrically for both possible winding directions.
- the Wrap angle of the web 1 on a roller segment 3 is 5 ° to 30 °, preferably between 8 ° and 20 °, in order to prevent the escape of those starting with the web 1 Favor air layer.
- each roller segment 3, 3 ' consists of a roller jacket 18, preferably made of metal, on which an outer running layer 19 made of rubber is applied.
- the roller shell 18 is on two lateral roller bearings 20 on one Axis 21 fastened freely rotatable. It is graded at each side end like this designed that the end of the contactless assembly in the annular groove 16 of the Bearing plate 5, 5 'immersed. The assembly takes place in such a way that the axial clearance between the end faces of a roller segment and the rear wall 17 in the Ring groove 16 is 0.2 mm to 5 mm, preferably about 0.3 mm.
- Each axis 21 is on both ends by means of a screw 22 on the disc-shaped Axle bracket 14 of the bearing plate 5, 5 'screwed.
- the screws 22 each extend from the outside centered on the axis of rotation 11 through the bore 15 of the axle support 14, with its head in the transverse groove 13 of the plate-shaped part 12 is partially sunk.
- the bearing plates 5, 5 'of two adjacent roller segments 3, 3 ' are alternately at the top or bottom of the fork-shaped bearing part 10 of the Carriage 6 attached. In Figure 3, the bearing plates 5 of the two outer Roller segments 3 arranged below, the bearing plates 5 'of the middle part above.
- the bearing plates 5 'of the middle roller segment 3 are for a clearer Represented drawn 180 ° around the axis of rotation 11 folded up. In the installed position are the back walls 17 of the bearing plates 5 'of the middle Roll segment 3 'exactly on the corresponding rear walls 17 of the bearing plates 5th the outer roller segments 3.
- the two the axes 21 of two adjacent Roller segments 3, 3 'bearing plates 5, 5' are thus in the space between the adjacent roller segments 3, 3 'one above the other and perpendicular to Axis of rotation 11 arranged displaceably against each other.
- the arrangement of the bearing plates 5, 5 'one above the other allows the required gap between two to keep adjacent roller segments 3, 3 'very low. To mark up To prevent sensitive webs 1, the gap is less than 5 mm, preferably it is between 0.8 mm and 3 mm.
- the coupled roller segments 3, 3 ' form a rigid in itself Pressure roller, which is pressed with the same pressure against a winding roller 2.
- the contact line of all roller segments 3, 3 'coupled together forms an exact one Just.
- a coupling of two adjacent roller segments 3, 3 ' is then advantageous if due to large thickness tolerances winding rollers 2 with zones of too strong differing winding reel diameters. Then it is undesirable that each roller segment 3, 3 'resting on the winding roll 2 adapts to the current diameter in its contact zone.
- a clutch two adjacent roller segments 3, 3 ' may be advantageous if one roller segment 3, 3 'with an excessive axial length over a winding roller 2.
- Switchable latches 23 are preferably used as coupling elements shown in Figures 1 and 2 - movable parallel to the axis of rotation 11 on the carriage 6th are attached.
- the bolts 23 are - for example by means of magnets or air cylinders - Movable back and forth along its axial direction in a guide 24 and move with their end into a corresponding opening in the guide 24 of the adjacent carriage 6.
- each winding roll 2 located roller segments 3 to a contact roller of the required axial Length interconnected without a shift of the roller segments 3 in axial direction or a replacement of contact rollers to the required Wrapping roll width is required. All roller segments 3 that are not required are pneumatically moved to an end position. With a format change without manual intervention correspondingly changed groups of roller segments 3 activated. If necessary, adjacent and active roller segments 3 by the switchable bolt 23 to a rigid contact roller with an exactly straight Contact line coupled together. The contact rollers interconnected in this way are pressed against the winding rollers 2 under an adjustable pressure in order to To largely prevent air from entering the winding rollers 2.
