Description

ARRANGEMENT FOR ACHIEVING A CORELESS PAPER ROLL
The invention relates to an arrangement by means of which finished paper generated in the process of paper manufacture can be wound in web-width to form a roll without using in the roll a core to form a centre hole. However, thanks to a pull-out winding axle a centre hole is formed in the roll.
Previously the use of core is generally known on forming a centre hole in the paper roll. Mostly, the roll is made of cardboard and as long as the width of the web to be wound. Winding takes place about the rotating core and, at the start, most suitably glue is used to facilitate the adhesiveness of web forward end onto the core. The use of cores causes remarkable costs within the paper industry and much energy is bound to their manufacture and they leave much waste.
By means of the arrangement of this invention also great dia-meter rolls generated in the so called dry end of the paper machine can be wound in web-width, stored and used without core. The invention is characterized in what is presented in the claims.
The advantage of the invention is cost saving thanks to the left-out core. The saving is due to the costs of core production, storing and transportation, and after-use handling that is not needed anymore. By means of the arrangement of this invention there will be a firm7 centre hole in the roll without using a supporting core. The centre hole size is determined by the axle diameter and can vary e.g. from 50 mm to 150 mm.
In the following the invention is disclosed with reference to the enclosed drawing, where Fig. 1 shows the axles to be pulled out from the roll and the arrangement moving them from the front. Fig. 2 shows the construction as per Fig. 1 with axles pulled out and the roll removed. Fig. 3 shows a winding equipment with bearing means that can be opened.
Fig. 4 shows the roll taken to the packaging station and axle pull-out f om the roll.
Fig. 5 shows the axle partly cut.
Fig. 6 shows another way of moving the axle. In figure 1 a winding arrangement as per the invention is presented, about the axle 1 of which a finished paper web from a paper machine is wound in full width. Axle 1 is formed of two parts la and lb, both of which are fastened with solid bearings. Bearing housings 2 are fastened to a supporting frame on both sides of roll 14. The axle parts can in this embodiment be pulled out separated from each other as per figure 2 so that a full roll 14 can be removed. Axle la, lb is rotated by means of a motor 4 and a gearing 11,12 in order to produce winding.
The travel motions of axle 1 parts la and lb are done by means of a link 8 fastened to a movable chain 7, into which link a flange 3 in the end of both axle parts is placed. Moving the chain takes place by a motor that rotates a chain gear. Flange 3 can rotate freely in flange 8.
In figure 6 another embodiment is presented, where bearing housings 16' slide in their horizontal guides 23 along with the axle parts as much as the travel motion. The horizontal guides are beams joined to the support frame and having an accurate sliding face 24.
In figures 1 and 2 an equipment is presented, spraying, e.g. silicone or some other lubricant on the axle surface and furnished with a pump unit 9 and a nozzle 10. Coating takes place e.g. while pushing axle parts together, when they are passing nozzle 10.
Heating of axle la, lb, takes place for instance as per figures 1 and 2, when the axles are pulled loose from each other to the extreme position. In tops of axles la, lb there are the counter parts qf the terminal, over which electric current can be conveyed from coupling unit 6 through terminal 6 poles into the axles. Inside the axles there are electric resistances and a temperature regulating thermostat, by means of which the temperature of axles is kept, at least in the winding point, at a proper rate from 120°C to 200°C.
A proper rate of the temperature of axles la, lb ensures hardening of the forward end of paper getting wound about the axles so that with the axles pulled out from roll 14 there will remain in the roll centre a hole corresponding to the axles. The hole retains its form merely thanks to the rigidity generated in the paper. When axle parts la, lb are moved tight against each other, there is in one axle lb a cylindrical steering surface 13 that gets its place in the corresponding hole of the other axle la. By means of the cylindrical face 13 it is possible e.g. to transfer rotation from one axle part to the other part For instance, on the surface there can be a thread, whereby the rotation of the other axle tightens the axles ever more to each other. There can also be in the join of the axles an inlet for electricity to the other axle or an inlet for heating pipes from one axle to the other.
Figure 3 shows a winding axle la, lb, which is placed on supporting pieces 15 and whose bearing houses 16 are right angled in order to place them so that they can be easily detached and locked on pieces 15. In this example swivelling closing means 17 are used, which get open on hinges and are pressed onto bearing houses 16. Bolts 17 are closed for instance pressing them shut by means of a hydraulic cylinder or mechanically through holes made for instance in part 17 of the closing means and frame 15 in order to produce a solid fastening. Furthermore, for bearing houses 16 there is advantageously a guiding groove in piece 15 to secure the alignment of the bearing house. Winding is carried out by means of motor 4 and gearing 11,12.
In one embodiment the bearing houses 16 can be opened, whereby they include a division plane running horizontally through the axle 1 middle line. Along with the opening of the upper closing means, the upper side of bearing house 16 is lifted up and so merely the axles la and lb can be lifted with roll 14 into the station in figure 4. In one end of axle la a coupling unit 18 is placed in order to connect electricity or heating pipes to axle la In coupling unit 18 there is a rotating terminal 22, whereby connection is possible when the axle is rotating.
According to figure 4 axle parts la and lb are not removed from roll 14 inside untill station 4, into which the roll with its axles and bearing houses has been moved, when the roll has reached its complete size. RoU 14 has been let down to rest on rotating rolls 19, the axle parts can then be removed and returned to frame pieces 15. In figure 4 station it is possible to furnish the roll ΛVUI wrapping førτoll protection. In figure 5 axle part lb is partly cut, whereby the axle part is at least at the winding point hollow for installation of a heating element 20. The heating element is an electric resistance cable or a heating pipe.
By means of the embodiments presented in figures 1 - 6 the coreless winding of paper, arriving from a production line, about axles furnished with bearings and rotating equipment, can be solved. The width of rolls 14 is typically from 1 to 10 meters and diameter more than 0,5 meter, even over 2 meters is possible. Then the diameter of axle 1 (la,lb) can be at the winding spot, for instance, from 50 mm to 150 mm.
Though only few example embodiments have been illustrated in the figures, many modifications and combinations are possible within the limits of the concept of this invention determined in the claims.
