Definitions
- the invention relates to a support roller winding machine for winding material webs, in particular paper or cardboard webs, onto cores.
- roll ejection and sleeve insertion devices which eject the full rolls from the roll bed when a roll is changed and insert new sleeves into the roll bed.
- an ejection bar which can be pivoted about the inlet-side support roller and has an ejection surface which extends as far as the support roller and whose upper limit in the pre-pivoted position extends into the region of The apex line of the outlet-side support roller extends.
- wound winding rolls with a small diameter can be clamped between the ejection surface of the ejection bar and the support roller via which the ejection is carried out and lifted out of the roller bed by a rotary movement of this support roller.
- DE-OS 40 03 504 describes a generic support roller winding machine which contains an ejection roller as ejection device, which is on the side, around the axis the swivel arms on the inlet side, which pivot the web from below into the roller bed and are freely rotatable.
- a device for applying an adhesive and a perforating device with which the web can be weakened are arranged in front of the feed roller on the inlet side.
- the web is first weakened and the weakened point is moved into the roller bed.
- the web is then severed by increasing the tension by rotating the winding roller with the support roller on the outlet side, while the ejection roller raises the winding roller somewhat from the support roller on the inlet side.
- the full winding rolls are then ejected from the discharge roller via the discharge roller on the outlet side.
- the ejection roller can eject full winding rollers with a larger diameter (e.g. 1000 mm) via the outlet-side support roller, it is necessary to arrange them at a certain radial distance from the inlet-side support roller. However, then it will not be able to lift winding rolls with a smaller diameter (e.g. 200 mm) from the infeed roller to sever the web.
- a larger diameter e.g. 1000 mm
- the invention has for its object to improve the winding reel ejection device in a generic support roller winding machine in such a way that it is able to lift winding rollers with widely differing diameters both from the inlet-side support roller for severing and also via the outlet-side support roller from the roller bed eject.
- an ejection bar with an ejection surface is used for ejecting a full winding reel from the roller bed, which is arranged for ejecting winding reels with a large diameter at a sufficient distance from the inlet-side support roller.
- a lifting roll in the space between the ejection surface and the support roller with the smallest possible distance from the Carrier roller arranged, which is able to lift winding rollers with a small diameter.
- the new sleeves can be inserted simultaneously with the ejection of the full winding rolls.
- a separate sleeve insertion device according to claim 3 enables the use of sleeves with a very large diameter.
- the freewheel lock acting only in one direction of rotation enables the removal of winding rolls from the roller bed, the diameter of which is too small for ejection.
- These winding rollers can be clamped between the outlet-side support roller and the lifting roller and can be lifted by rotating this support roller until they are clamped between the ejection surface and the support roller and so on.
- Figure 1 shows schematically the side view of a support roller winding machine according to the invention during winding.
- Figure 2 shows the start of a roll change after adhesive strips have been applied and the web is perforated.
- Figure 3 shows the lifting of the winding roll to cut the web.
- Figure 4 shows the ejection of a winding roll.
- FIG. 5 shows the insertion of a new winding sleeve
- Figure 6 shows the attachment of the beginning of the web to the new winding tube.
- Figures 7 to 9 show the removal of winding rolls with a very small diameter from the roller bed.
- FIG. 10 shows a carrier roller winding machine with a separate sleeve insertion device which can be pivoted about the outlet-side carrier roller.
- the carrier roller winding machine has two driven carrier rollers 1, 2, between which a roller bed 3 is formed, in which the winding rollers 4 rest on the carrier rollers 1, 2 during winding.
- Such double carrier roller winding machines are widely known and z. B. described in DE-OS 32 07 461, so that individual parts, insofar as they do not relate to the invention, are not dealt with.
- a downwardly angled pivot lever 8 is pivotally mounted in the machine frame by means of a piston-cylinder unit about an axis coaxial with the axis of rotation of the support roller 1.
- the levers 8 carry on their upper side a roller lifting and ejecting device with an integrated sleeve insertion device, which is described in more detail below.
- each pivot lever 8 At the top of the radially extending part of each pivot lever 8 is outside the cross-sectional area of the support roller 1 over the working width extending ejector bar 9 attached.
- the ejection bar 9 consists of a bearing part 10 which is approximately fork-shaped in cross section and which is open in the direction of the pivoting-in movement to the roller bed 3.
- a lifting roller 11 At the free end of the arm of the bearing part 10 adjacent to the supporting roller 1, a lifting roller 11 extending over the working width of the machine, that is to say over the axial length of the supporting rollers 1, 2, is mounted with the smallest possible distance from the supporting roller 1.
- the lifting roller 1 1 is rotatable in the same direction as the direction of rotation of the support roller 1 - in the exemplary embodiment counterclockwise - rotation in the opposite direction - ie clockwise - prevents a freewheel lock, not shown.
- a lever 12 is articulated, on which the ejection surface 1 3 is attached.
- the ejection surface 1 3 can be folded about an axis parallel to the support roller axis 1 by means of a piston-cylinder unit 14 fastened to the angled part of the swivel arm 8 and is supported in the folded-down position on the arm of the bearing part 10 adjacent to the support roller 1.
- the piston-cylinder unit 14 is only indicated in FIGS.
- the ejection surface 1 3 extends in the radial direction to the support roller 1 from the area of the lifting roller 11 so far that heavy winding rollers 4 can be easily ejected via the support roller 2 from the support roller bed onto a pivotable lowering platform 1 5 arranged next to the support roller 2.
- the bearing part 10 carries between its arms a sleeve channel 16 which extends over the working width, the outlet opening of the sleeve channel 16 between the lifting roller 11 and the lever 12 being able to be opened and closed by pivoting the ejection surface 13. So that the lifting roller 1 1 can lift a winding roller 4 slightly from the support roller 1 without the winding roller 4 immediately contacting the ejection surface 13, it protrudes somewhat from the ejection surface 1 3 when it is in the ejection position with the outlet opening of the sleeve channel 1 closed 6 is folded down. The ejection surface 1 3 thus extends in the folded-down position at an acute angle to the tangent to the outer side of the lifting roller 11 which runs through the axis of the support roller 1.
- the web 6 On the inlet side, just before the web 6 touches the support roller 1, there are perforating devices 17 and subsequently in the area of the web 6 wrapped around Carrier roller 1 arranged a series of tape dispensers 1 8 across the working width. With the perforating device 17, the web 6 can be weakened along a transverse line.
- the adhesive web dispensers 1 8 apply a series of double-sided adhesive tapes to the web 6, with which the newly created web beginnings, after severing the web 6, are adhered to the new sleeves 7 and the webs to the finished winding rolls 4.
- a machine-wide support 19 is arranged below the gap between the support rollers 1, 2, to which a number of free-running belts 20 are fastened over the working width, which are moved by moving the support 19 up to the inlet-side support roller 1 for holding the newly created path start let it put on after cutting.
- FIGS. 2 to 6 In the carrier roll winding machine shown in FIG. 1 during winding, a winding roll change is carried out as shown in FIGS. 2 to 6.
- the machine is stopped again, and the full winding rollers 4 are lifted slightly off the support roller 1 with the lifting roller 11, while they are not on the ejection surface 13 of the ejection bar 9 issue.
- the support roller 2 is rotated counterclockwise, the web 1 tears through the weakening line 21, if this was not already done when the winding rollers 4 were raised.
- the winding rollers 4 are rotated until the web ends with part of the adhesive strips 22 have been moved through the gap between the winding rollers 4 and the lifting roller 11. The web ends are at the full winding roll 4 glued.
- the swivel arms 8 are then pivoted further upward, so that the ejection surface 1 3 presses the winding rollers 4 away over the support roller 2 onto the lowering platform 15.
- the sleeve trough 1 6 moves with the set of new sleeves 7 into the roller bed 3 (Fig. 4). In this position the ejection surface 1 3 is opened up so that the sleeves 7 roll into the roller bed 3 from the inside of the ejection surface 1 3 (FIG. 5).
- the sleeves 7 roll into their winding position in the roller bed 3.
- the winding machine After placing the pressure roller 23, the winding machine is started. The beginning of the web provided with an adhesive strip 22 adheres to the sleeves 7 (FIG. 6). After winding, the support 19 is lowered with the belts 20 and the winding machine can be accelerated to full winding speed.
- the swivel arms 8 With a new set of sleeves 7 lying in the sleeve trough 1 6, the swivel arms 8 are pivoted over the supporting roller 1 until the lifting roller 11 lies against the winding rollers 4 to be ejected and presses them against the supporting roller 2 with a defined force (FIG. 7).
- the support roller 2 is then driven clockwise.
- the rollers 4 are raised by the rotational movement of the support roller 2, since the free-wheel lock of the lifting roller 11 does not permit a clockwise rotational movement.
- the piston-cylinder unit permanently presses the swivel arms 8 in the direction of the support roller 2, so that the ejection surface 1 3 bears against the rollers 4 as soon as these have lifted so far that they are no longer held by the lifting roller 11.
- the winding rollers 4 between the support roller 2 and the ejection surface 1 3 are conveyed up to the region of the apex line of the support rollers 2 (FIG. 8), where they are opened by opening the ejection surface 1 3 over the apex the support roller 2 are pushed onto the lowering platform 1 5.
- the ejection surface 1 3 is opened, the new winding tubes 7 are simultaneously placed in the roller bed (FIG. 9). The track starts will be then attached to the new sleeves 7 in the manner explained under the description of FIG. 6.
- FIGS. 1 to 9 show a carrier roller winding machine with a separate sleeve insertion device 24 which can be pivoted about the outlet-side carrier roller 2.
- the components which correspond to the exemplary embodiment according to FIGS. 1 to 9 are identified by the corresponding reference numbers.
- a separate sleeve insertion device 24 may be required if sleeves 7 with such a large diameter (z. B. greater than 230 mm) are used that there is not enough space available for installing the insertion device in the ejection bar 9.
- the sleeve trough 16 is attached to the end of two swivel arms 25 which can be swiveled counterclockwise around the axis of the outlet-side support roller 2 from a lowered sleeve receiving position to an approximately vertical position, in which the sleeves 7 from the sleeve trough 1 6 into the roller bed 3 rolls.
- the ejection bar 9 carries the lifting roller 11 in the extension of the ejection surface 1 3. In this embodiment, too, the lifting roller 11 protrudes somewhat circumferentially against the ejection surface 1 3, and thus the ejection surface 1 3 runs at an acute angle to the tangent extending through the axis of the support roller 1 to the outer side of the lifting roller 11.
- a winding roll change is carried out analogously to the process according to FIGS. 2 to 6, with the difference that after the winding rolls 4 have been ejected and lowered with the lowering platform 15, the ejection bar 9 with the lifting roll 11 is first pivoted back into the waiting position and then the new sleeves 7 are inserted into the roller bed 3 by pivoting the swivel arms 25. Already during the swiveling back of the sleeve channel 16 the new web beginnings can be glued to the new sleeves 7. In the embodiment according to FIG. 10, a roll change takes a little more time, since the new sleeves 7 are not inserted into the roll bed 3 at the same time as the full winding rolls 4 are ejected, but in a separate step.
