Definitions
- the invention relates to a winding machine according to US-A-3 524 603 according to the preamble of claim 1.
- Such winding machines also called “pop rollers" generally form the end section of a paper machine in order to bring the paper web obtained there into roll form. However, they are also used to rewind an already finished roll so that a new roll is created.
- the roll should have very specific properties, especially as far as the winding hardness is concerned.
- the winding hardness should drop from a certain initial value to a final value.
- the waste should be as even as possible from the first to the last layer. It should have a certain gradient, i.e. not be too strong and not too weak.
- the course of the winding hardness should under no circumstances have jump points, e.g. a sudden drop.
- Known means of influencing the winding hardness are two measures that are used, for example, in slitter rewinder.
- One is to subject the web to a more or less strong tension when winding it up.
- the other measure is to keep the role more or less strong Pressing the support roller, for example by applying pressure to the axes of the spool, or by pressing a rider roller, which is arranged parallel to the roll being created and pressed against it, so that a line pressure is created between the roll and the support roll.
- a line pressure between the resulting roll and the support roller is often generated in the primary section by the weight of the reel.
- the drum is extremely heavy. It reaches a dead weight of several tons, so that a correspondingly high line pressure is created. This is responsible for the extremely high winding hardness of the core of the roll.
- the problem could not be solved by bringing the reel to winding speed in the upper apex of the support roller before unwinding a new reel, until the peripheral speed of the reel and support roller were synchronized.
- the other problem - namely the above-mentioned steep drop in winding hardness in the end area - has not yet been solved.
- the period of time during which the resulting roll is transferred from the primary section to the secondary section is particularly unfavorable during the entire winding process. During this period, the winding hardness is practically out of control.
- the invention has for its object to design a winding machine according to the preamble of claim 1 such that the winding hardness has the desired course from the beginning to the end of the roll, i.e. that the extreme hardness in the core area is avoided and that the winding hardness is under control at every moment of the winding process.
- the mechanical effort should of course be kept as low as possible.
- the cam disks achieve a precisely metered relief of the large reel weight.
- the two cams can each engage one axis of the reel, for example. Because they are connected to the primary levers, they pass through the primary path. By twisting it around its own horizontal axis, it is possible to precisely determine the extent to which the effect of the weight of the drum is reduced.
- the rotation of the two cams around its own axis can be designed, for example, such that initially - in the upper vertex area and thus in the first position - there is still no contact between the outer surface of the support roller and the outer surface of the reel, but this happens after some Angular degrees of the primary lever occurs. Then by further turning the cam accordingly at any time, i.e. precisely meter the line force between the reel and the idler roller at every point along the route.
- the device according to the invention is able to position the drum in such a way that its outer surface (or the outer surface of the wound paper) is one takes up a finite distance from the lateral surface of the support roller, and that this distance can also be continuously changed in any manner until finally contact between the two named lateral surfaces.
- the invention is explained in more detail with reference to the drawing.
- the drawing shows a so-called pop roller.
- Such a pop roller is used to wind up a running paper web.
- the paper web is not shown here, but only the role formed from it.
- the paper web is fed from the left side of the pop roller in the drawing.
- the pop roller has a web-wide support roller 1.
- a drum 2 has trunnions 3 at both ends. Each trunnion is supported in the fork 4 of a primary lever 5.
- the two primary levers which are accordingly also located in the region of the end faces of the supporting roller 1 and thus also the drum 2, can be pivoted about a pivot point 6b according to the arrow 7 on a circular path by means of a pneumatic drive 6a.
- the pivot center of the primary lever 5 can be offset somewhat from the axis of rotation of the support roller 1. However, it is an advantage of the invention that the two can be concentric with each other.
- the drum 2 is initially in its position I, either exactly or almost exactly vertically above the support roller 1. In this position, it is still empty, ie not yet wrapped in paper.
- the support roller 1 is then driven in the direction of the arrow 8, and with it the drum 2 in the direction of the arrow 9.
- the paper web is thus wound more and more onto the drum 2.
- very considerable forces act on the paper web. These forces have a decisive influence on the winding hardness of the resulting roll. Since the roller gains weight on its way according to arrow 7, this also acts and thus influences the winding hardness.
- a cam disk 10 is provided in the region of the ends of the drum 2.
- the two cams 10 are each mounted on one of the two primary levers 5. They thus take part in the pivoting movement of the primary lever 5.
- the cam disks 10 act - indirectly or directly - on the reel 2. They are supported either against the outer surface thereof, in the edge region, mind you, or against the bearing journal 3.
- a load cell 11 can be provided between each cam disk 10 and the associated primary lever 5. This measures the force that prevails between the drum 2 and the cam disk 10. The mode of operation of the cam plate 10 and the load cell 11 will be discussed further below.
- the two primary levers 5 migrate in the course of the operation of the pop roller together with the drum 2 and the partial roll of the paper web located thereon, as mentioned above - in the direction of arrow 7 - and thus move from position I of the drum into its position II. In position II, the curve movement of the drum with partial roll has ended.
- drum 2 with partial roller are delivered from the primary lever pair 5 to a secondary lever pair 12.
- Each secondary lever also has a fork 13 for receiving the relevant journal 3 of the reel 2.
- a pneumatic or hydraulic drive 14 engages the two secondary levers 12 and pivots the secondary levers to the right, so that the reel 2 with the paper roll, which is now growing, runs through a horizontal secondary section until it finally reaches position III, where the roll is finished.
- the primary route is particularly critical with regard to the winding result, that is the route between positions I and II.
- the transfer phase from the primary route to the secondary route is particularly critical.
- the problems previously encountered are now solved with the cam disks 10 according to the invention.
- the cams 10 and - if necessary - the load cells 11 work as follows: They are both driven, on the driver side and on the drive side of the pop roller in a synchronized manner.
- the drive is controlled via an angle encoder.
- the two cams relieve the weight of the reel and the weight of the resulting roll. It is possible to control the line force between the drum 1 and drum 2 in a targeted manner.
- the angular position of the primary lever 5 and the forces measured on the load cell 11 are used as manipulated variables.
- the device according to the invention is able to continuously lift the drum 2 in such a way that there is no contact with the carrying drum 1 at all.
- This mode of operation is particularly suitable for papers that are sensitive to surface pressure, such as NC papers or high-quality coated papers.
