Definitions
- the invention relates to a guide head for heavy winding rolls according to the preamble of claim 1.
- guide heads are used to hold the winding rolls during winding or unwinding.
- Two guide heads each freely rotatable or drivable in the winding machine (e.g. in winding frames), move into the winding tube of the winding roll on each side.
- winding rolls are not supported during winding or unwinding, e.g. B. by a support or support roller, there may be a deflection of the sleeves usually made of cardboard in the area between the two guide heads, which causes roll errors in particularly heavy winding rolls due to their own weight.
- the roller then turns somewhat eccentrically in the area of the sleeve, which results in restoring forces during rotation, which lead to shifting of the winding layers. These layer shifts can cause core locations and crepe folds in the core area of the winding roll.
- a generic, arranged on a drivable shaft end clamping head which consists of a guide part and a torque-transmitting part.
- the guide part contains a hub which is connected in a rotationally fixed manner to the shaft end and has an essentially cylindrical, slightly convex surface which is surrounded by a support sleeve.
- the support sleeve has axial slots distributed over the circumference at the end located towards the shaft end, so that it can perform a tilting movement so that its circumferential surface can follow the bending line of the winding sleeve.
- the second part which is connected in a rotationally fixed manner to the guide part, has a segment sleeve with multiple axially slits with pressure elements which press the segments radially outward when the segment sleeve is rotated, so that torques can be transmitted.
- the second part has radial play with respect to the first part and can be tilted so that it can adapt to the orientation of the sleeve.
- This very complex clamping head with radially expanding clamping segments is designed for the transmission of torques.
- the guide part sits non-rotatably on the driven shaft, which must therefore be rotatably mounted in the winding machine.
- the invention has for its object to provide a structurally simple guide head that can adapt to the bending line of a sleeve.
- the guide part is rotatably mounted on a non-rotatable pin which is therefore easy to store in the winding machine. If no external radial forces act, the support element centers the guide part coaxial to the pin axis so that the guide heads can be easily inserted into new winding tubes.
- the arrangement of the pivot bearing in the region of the pin end, ie outside the machine part to which the guide head is attached, has the further advantage that the non-rotatable pin can be easily axially displaceably mounted, e.g. B. by a centrally acting spindle drive. Since the two guide heads holding a winding roll have to be moved apart in the axial direction for unloading or hanging in a winding roll or a winding tube, this can be done without moving the machine part to which the guide heads are attached. The guide heads can simply be sunk into the machine part.
- Fig. 1 shows a longitudinal section through a guide head according to the invention.
- the guide head shown in Fig. 1 is used to hold a winding roll when winding in a winding machine.
- the known winding machines for winding heavy winding rolls from paper or cardboard webs have individual winding stations, each of which consists of two winding blocks 1, one of which is partially shown in FIG. 1.
- a guide head which can be moved into the sleeve 2 of a winding roll is fastened to each winding block 1 and is described in more detail below.
- the guide head consists of a pin 3, 4, 5 with a circular cross-section, which is rotatably and axially displaceable with its part 3 in the winding block 1 by means of a spindle drive for countersinking the guide head when changing the winding reel.
- the end of the pin 3 consisting of two parts 4, 5, each with a decreasing diameter, is located outside the winding block 1.
- a hollow cylindrical outer guide part 6 is rotatably fastened, the outer diameter of which is the inner diameter the sleeve 2 is adapted.
- the guide part 6 has at its end facing the winding block 1 a bead-like stop 7 for the sleeves 2, at its other end it extends approximately beyond the length of the parts 4, 5 of the pin 3.
- the guide part 6 is fastened on the pin 3 by means of an angularly movable radial bearing 8 and can be tilted to a limited extent, which is arranged in the region of the outer part 5.
- the angularly movable radial bearing 8 is a spherical roller bearing (as in the present example) or a spherical ball bearing, the outer race of which is fitted on the inner surface of the guide part 6 and the inner race of which is fitted on the outer surface of the journal part 5.
- the spherical roller bearing 8 is secured against axial displacement by a locking ring 9.
- the beginning of the guide part 6 is rotatable on the pin part 4 and supported by a circumferential, radially elastically deformable element.
- a needle bearing 10 is seated on the pin part 4 and an elastic O-ring 11 is drawn over the outer raceway thereof.
- the O-ring 11 presses the guide part 6 into a position coaxial to the axis of the pin 3, provided that no external forces, e.g. B. the roll weight.
- the O-ring 11 likewise seals the guide head on the inside on the side facing the winding frame 1.
- the guide part 2 is closed on the inside with a disk 12 which is sealed with a sealing ring 13 and has a central lubrication opening 14. Lubricant can be supplied via the opening 14 into the space thus closed with the two bearings 8, 10.
- the sleeve 2 of the winding roll held laterally by two guide heads bends due to its own weight.
- the guide part 2 of the guide head is able to follow the bending line of the sleeve 2, it adapts by tilting perpendicular to the pin axis of the bending line of the sleeve 2.
- the tilting movement is limited by the O-ring 11, the tilting angle to the pin axis is max. 10 °, preferably between 0.5 and 5 °.
