Definitions

the invention relates to and a device for unwinding a web of material, in particular a paper web, in, for example, a winding reel changer of a rotary printing press according to the preamble of claim 1.
DE 35 21 582 C2 discloses a device for clamping winding cores, in which rotatable clamping cones are provided with clamping elements in the form of tubular segments. These tensioning elements expand and thus clamp the winding core on the tensioning cones.
a disadvantage of this device is that the large mass moments of inertia that occur today with large diameters and large widths when the speed of the winding roller changes cannot be transmitted via the tensioning cones.
DE 42 34 344 A1 shows a device for a production machine for changing rolls of sheet material.
a core of the roll is picked up by spindles and suction cups arranged in a disk act on the end face of the roll. These suction cups or the disc are connected torsionally rigid with a spindle.
a disadvantage of this device is that the edges of the web can be damaged if the diameter of the roll is below the diameter of the disc.
the invention has for its object to provide a device for unwinding a web with torque acting temporarily on an end face of a winding roll, in which damage to the web is prevented, even if a diameter of the winding roll is smaller than a diameter of the torque transmission elements.
very large torques can be transmitted with the device according to the invention without slip, so that damage to a winding core is excluded.
the possibility of transmitting very high torques means that winding rolls with a very large mass moment of inertia can be braked in a very short time. The time required to stop the winding roll during a quick stop is thus considerably shortened and the machine safety is increased.
torque transmitting elements that interact with one end face of the winding roll can be axially displaced independently of the tensioning cones. Damage to the web is thus avoided, even if a diameter of the web becomes smaller than a diameter of the torque transmission elements.
the device according to the invention is shown in the drawing and is described in more detail below.
a device for unwinding a web 1, in particular a paper web is integrated, for example, in a winding reel changer of a rotary printing press.
a shaft 4 is mounted in side frames 2, 3 of the winding roll changer of a rotary printing press, on which a right and left bearing arm 6, 7 are fastened. These bearing arms 6, 7 are axially displaceable on the shaft 4, but arranged in a rotationally fixed manner by a distance a, z. B. 2.5 m, the bearing arms of a width b, z. B. 2 m, the web 1, ie to adapt a winding roll 8 and to determine a position of the winding roll 8 with respect to a central axis 9 of the rotary printing press.
the shaft 4 can be pivoted by means of drives (not shown) in order to bring the winding roll 8 into different positions required for changing the winding rolls.
the left bearing arm 6 has a first bearing, for example in a bore 12 lying concentrically to an axis of rotation 11 of the winding roller 8.
B. needle bearing 13 which receives a tubular hollow shaft 14 rotatable and axially displaceable.
Actuating devices 16 act on this hollow shaft 14, which can move the hollow shaft 14 axially, even with simultaneous rotation of the hollow shaft 14.
the end 17 of the hollow shaft 14 facing away from the winding roll 8 has a circumferential annular ring which is perpendicular to the axis of rotation 11
Axial bearings can be arranged between the collar 18 and the fork-shaped ring 19, for example on both sides 21, 22 of the collar 18.
a fork segment are formed such that cam rollers act on both sides of the collar, the bolts of which are connected in parallel via a coupling.
One or more positioning drives are arranged parallel and concentric to the axis of rotation 11.
single-acting, spring-loaded pneumatic cylinders 23 are used as positioning drives.
Other known positioning drives such as e.g. As hydraulic cylinders, spindle drives, linear drives, etc.
This disk 26 is provided on its two plane sides 27, 28 with friction linings 29, so that the friction linings 29 are connected to the hollow shaft 14 in a torsionally rigid manner.
These friction linings 29 can be in the form of annular disks with an outer diameter d1, e.g. B. 700 mm, which are simply integrally connected to the disk 26 of the hollow shaft 14. Likewise, however, are only circular segment-like friction linings 29 or other shapes possible.
the disc 26 of the hollow shaft 14 can also be designed as a narrow disc, which is then connected to the hollow shaft 14, for example by means of spokes, or z. B. consist of individual plates provided with friction linings 29, attached to support arms. These support arms can be designed so that they can be swiveled in and out of the end face of the winding roll.
a second storage for. B. needle bearing 31, which receives a shaft 32 concentrically rotatable about the axis of rotation 11 and axially displaceable.
the shaft 32 is provided with an adjusting device 33, which can move the shaft 32 axially, even when the hollow shaft 14 rotates.
This actuator 33 can adequately the actuator 16 of the hollow shaft 14, z. B. with pneumatic cylinders 34 to be executed.
An end 36 of the shaft 32 facing away from the winding roll 8 is connected by means of a coupling 37 which transmits torques and at least compensates for axial displacement of the shaft 32, e.g. B. spline connection with a braking device 38, for. B. disc brake, with a drive 39, z. B. three-phase motor, and with a speed sensor 41, z. B. incremental encoder coupled.
An end 42 of the shaft 32 facing the winding roller 8 is provided with a tensioning cone 43 known per se for receiving a tubular winding core 44 of the winding roller 8.
This clamping cone 43 can have, for example, pneumatically operated, expanding jaws.
the hollow shaft 14 and the shaft 32 are connected by means of a switchable, torsionally rigid coupling 46.
this coupling 46 is designed as a switchable spline connection.
An axially extending region of the shaft 32 is profiled as a spline shaft 47 and a spline hub 48 is rigidly fastened in the hollow shaft 14.
the respective splines 49 of spline shaft 47 or spline hub 48 are tapered at their two ends 51, 52, for. B. arrow-shaped in the axial direction. But z. B. also known, radially acting friction clutches can be used.
the right bearing arm 7 is a mirror image of the described left bearing arm 6. However, the drive 39 and the speed sensor 41 can be omitted here.
a sensor 53 for. B. an optoelectric reflection button, for detecting a certain limit diameter dG, z. B. 800 mm Winding roll 8 attached.
the mode of operation of the device according to the invention is described with the help of the left bearing arm 6 with its elements, the mode of operation of the right bearing arm 7 is corresponding (but a mirror image).
the shaft 32 with its clamping cone 43 and the hollow shaft 14 with its disk 26 provided with friction linings 29 are in their position remote from the winding rollers, ie the pneumatic cylinders 34 are extended.
the winding roll 8 is placed between the bearing arms 6, 7 in such a way that the winding core 44 is approximately aligned with the tensioning cone 43.
the pneumatic cylinder 34 of the adjusting device 33 By pulling the pneumatic cylinder 34 of the adjusting device 33, the tensioning cone 43 is pushed into the winding core 44.
the jaws of the clamping cone 43 then expand by means not shown.
the winding core 44 or the winding roll 8 is hereby connected to the tensioning cone 43 in a frictional or positive manner.
the speed of the shaft 32 is then queried by means of the speed sensor 41 and the limit diameter dG of the winding roll 8 by means of the sensor 53. If the shaft 32, ie the winding roller 8, and an actually existing diameter d2 of the winding roller 8 corresponds at least to the limit diameter dG, the release for the axial displacement of the hollow shaft 14 in the direction of the winding roller 8 takes place.
the pneumatic cylinders 23 By venting the pneumatic cylinders 23, the hollow shaft 14 becomes in the direction Winding roll 8 shifted shortly after being released of the friction linings 29 from the bearing arms 6, 7, the spline shaft 47 meets the spline hub 48.
Trowel 49 and grooves 54 of the spline shaft 47 are not aligned with the spline hub 48, the tapered ends 51, 52 of the trowel 49 produce a slight rotation of the hollow shaft 14 , so that the spline shaft 47 and spline hub 48 slide into each other as the axial movement of the hollow shaft 14 progresses.
Hollow shaft 14 and shaft 32 are thus connected to one another in a torsionally rigid manner and are thus rotating synchronously.
the hollow shaft 14 is axially displaced by the pneumatic cylinders 23 until the friction linings 29 are pressed against an end face 56 of the winding roll 8. There is now a frictional connection between the friction linings 29 and the winding roller 8, which can transmit torques. Is z. B.
the winding roll 8 in work function the web 1 is unwound at a uniform peripheral speed at a constant production speed.
the actual diameter d2 of the winding roll 8 decreases and the speed increases. This is carried out via the speed-controlled drive 39. If a quick stop of the winding roll 8 is now necessary, a braking torque is transmitted to the shaft 32 via the braking device 38. As long as the friction linings 29 cooperate with the end face 56 of the winding roller 8, ie as long as the diameter d2 of the winding roller 8 is greater than the limit diameter dG, the clutch 46 will Braking torque branches.
the clutch 46 transmits part of the braking torque to the hollow shaft 14, which in turn is transmitted to the winding roller 8 by means of the friction linings 29. Overloading of the winding core 44 is thus excluded. If no quick stop is required, after reaching the limit diameter dG of the winding roll 8, the pneumatic cylinders 23 are vented by a signal from the sensor 53, and the hollow shaft 14 is displaced axially away from the winding roll 8 by spring force.
the coupling 46 decouples the shaft 32 from the hollow shaft 14 before the friction linings 29 reach the bearing arm 6, and the hollow shaft 14 is freely rotatable.
the friction linings 29 are pressed against the bearing arm 6 by further displacement of the hollow shaft 14. As a result, the rotational movement of the hollow shaft 14 is braked and stopped. If there is a quick stop, the significantly reduced mass of the winding roll 8 is stopped by a braking torque, which is only transmitted by the tensioning cones 43.
