Description

Method in threading of a paper web
The invention relates to a method in threading of a paper web in connection with the reeling up process, wherein a paper web to be guided over a reeling cylinder is passed in full width via a nip contact formed between the reeling cylinder and a reeling core to be driven, to the opening of a pulper below the nip contact before cutting the paper web and guiding the same to the reeling core, and wherein on the outer surface of the reeling cylinder, especially on the sector in which the outer surface of the reeling cylinder and the paper web are substantially close to or in contact with each other, a pressure effect deviating from the pressure of the environment is exerted from inside the reeling cylinder.
As for the state of art, reference is made to publications FI-74446 and FI-98506, which disclose a Pope-type reel-up for paper web, in which negative pressure is generated inside the shell of the reeling cylinder, the negative pressure affecting the outer surface of the shell via a perforation on the shell. The aim is to prevent the slip between the reeling cylinder and the paper web by means of the negative pressure. The solution is functional as such, but in present embodiments, when the web speeds of the paper web have become higher, problems have arisen especially in the implementation of the threading, thus resulting in the development of the present invention.
At present, a suction effect exerted on the tail is also used in reel-ups in connection with the threading, the suction effect being produced by means of a suction zone located in the edge area of the reeling cylinder, wherein the tail is separated from the reeling cylinder after the suction zone by means of an air doctor or a mechanical doctor. After the tail has been passed through the reel-up, the paper web is conveyed in full width to the pulper until the quality of the paper web is stabilized. Thereafter the paper web is lifted up on the reeling cylinder, which has been brought into a nip contact corresponding to the tangential entrance line of the reeling core with the reeling cylinder. When the reeling up process continues, the reeling core is transferred to a final reeling position, wherein the nip contact of the final reeling between the reeling cylinder and the paper reel formed on the reeling core is located substantially on the same horizontal level with the fulcrum of the reeling cylinder.
A special problem that has arisen is that the air blast produced by the air doctor is directed to a direction which is at least to a certain extent opposite to the travel direction of the tail or the full-width paper web, wherein the increase in web speeds, in particular, complicates the act of keeping the full-width paper web in connection with the reeling cylinder and in contact with the outer surface of the same, and at the same time it is not possible to pass the web to the pulper in connection with the threading for a long period of time. A doctor beam placed underneath the reeling cylinder occupies a space of fixed size, which could be used in present embodiments as a space for locating other functional members which are important in view of the reel-up.
One purpose of the present invention is to eliminate the above- presented problems related to prior art to a large extent, thus improving the state of the art prevailing in the field. To attain these purposes, the method according to the invention is primarily characterized in that a pressure effect is produced from a combination of a negative pressure and a positive pressure in such a manner that in the travel direction of the paper web, the negative pressure effect is exerted on the paper web at least primarily before the point of location of the nip contact of the final reeling, and the positive pressure effect is exerted on the paper web at least primarily after the area of location of the nip contact of the final reeling. One advantage of the solution that can be mentioned in this context is, first of all, that the release or detachment effect produced by the positive pressure zone and exerted on the tail or the full-width paper web can be directed in such a manner that it promotes the transfer of the tail or the full-width paper web to the pulper, and secondly, the fact that savings in space are attained, because the release effect exerted on the tail or the full-width paper web is produced by means of an apparatus inside the reeling cylinder.
The other dependent claims present some preferred embodiments of the method according to the invention. The invention will be illustrated in more detail in the description hereinbelow, in which reference is made to the reel-up shown in a schematical side view in the appended drawing.
The method according to the invention is applied in the threading of a paper web when a continuous reeling up process is started. Between a reeling cylinder 1 and a reeling core 2 entering a drive, a nip contact NK is formed, said nip contact forming the tangential entrance line of the reeling core, via which a paper web PR guided over the reeling cylinder 1 is passed in full width to an opening 3 of a pulper P underneath the nip contact NK, after the tail (not shown) has been passed through the reel-up in a manner known as such. The drawing shows a situation before the paper web PR is cut and guided to the reeling core 2. These stages, and especially the so-called final reeling stage, wherein the reeling core 2 is transferred in the direction of arrow 4 along the outer surface of the reeling cylinder 1 to a nip contact position NKL of the final reeling, wherein the nip contact is located substantially close to the fulcrum of the reeling cylinder 1 in the horizontal direction, are not described in more detail in this context, because these stages are disclosed in prior art patent literature of the field, e.g. in the reference publications FI-74446 and FI-98506.
In a manner characteristic to the invention, a pressure effect deviating from the pressure of the environment is exerted on the outer surface 1a of the reeling cylinder 1 , especially on a sector S in which the outer surface 1a of the reeling cylinder 1 and the paper web PR are close to or in contact with each other. This pressure effect is produced from a combination of a negative pressure and a positive pressure in such a manner that in the travel direction (arrow KS) of the paper web PR a negative pressure effect (sector 1 ) is exerted on the paper web at least primarily before the point of location (or the area of location) of the nip contact NKL of the final reeling, and a positive pressure effect is exerted on the paper web (PR) at least primarily after the point of location (or the area of location) of the nip contact NKL of the final reeling (sector S2). Advantageously, the negative pressure effect is terminated (sector S1) before the nip contact NKL of the final reeling, and the positive pressure effect is initiated (sector S2) substantially at the point of location of the nip contact NKL of the final reeling. It is advantageous, especially to balance the pressure effects and to produce a sealing area, that an intermediate zone (sector S3) is placed between the negative pressure and positive pressure zones, the intermediate zone being free of the negative or positive pressure effect, in other words it is in the pressure of the environment.
A combination pressure effect (sectors S1-3) is exerted on a sector of the reeling cylinder 1 , which covers 180° at the most of the nip contact point NKL of the final reeling in a direction opposite to the direction of rotation of the reeling cylinder 1 (counterclockwise in the drawing), and 45° at the most in the direction of rotation of the reeling cylinder 1 (clockwise in the drawing). More precisely, this combination pressure effect (sectors S1-3) is exerted on a sector of the reeling cylinder 1, which covers 155° at the most of the nip contact point NKL of the final reeling in a direction opposite to the direction of rotation of the reeling cylinder 1 (counterclockwise in the drawing), and 30° at the most in the direction of rotation of the reeling cylinder 1 (clockwise in the drawing).
The intermediate zone (sector S3) located between the negative pressure and positive pressure zones of the combination pressure effect (sectors S1-3) is positioned in such a manner that it covers 35° at the most, preferably 20 to 30°, advantageously 25° of the nip contact point NKL of the final reeling in a direction opposite to the direction of rotation of the reeling cylinder 1 (counterclockwise in the drawing).
Because the method according to the invention is applied in the threading of a full-width paper web PR, it is advantageous that at least one, preferably both pressure effects (sectors S1 and S2) cover substantially the entire width of the reeling cylinder for example in blocks or parts which are substantially as wide as the entire reeling cylinder and which can be formed as said negative and/or positive pressure zones which can be guided apart from each other in the lateral direction of the reeling cylinder 1. The first block or part containing the negative and/or positive pressure zones is formed in the edge of the reeling cylinder to be used in tail threading. In addition, a second block or part composed of one or several parts and containing the negative and/or positive pressure zones is produced to cover the outer surface of the reeling cylinder in the lateral direction, with the purpose of using said zone/zones especially in the threading of the full- width paper web PR.
Typically, the nip contact point NKL of the final reeling is at the lowest level of height on the horizontal plane extending via the fulcrum of the reeling cylinder 1 , wherein the positive pressure zone (sector S2) thus begins from this horizontal plane, being directed downwards e.g. approximately 30°. The intermediate zone (sector S3) also begins from this horizontal plane and is directed upwards, e.g. approximately 25°. The negative pressure zone (sector S1 ) in turn, functions as an extension to the intermediate zone in a direction opposite to the travel direction of the paper web PR, e.g. approximately 130°. The angular area of the negative pressure zone (sector S1) is at least partly determined on the basis of the mutual placement of a leading roll 5 and the reeling cylinder 1 , which defines the inlet angle of the paper web PR in connection with the outer surface 1a of the reeling cylinder 1 with respect to the horizontal plane.
The term "nip contact point NKL of the final reeling" can also refer to a position in which an empty reeling core is brought into the normal "threading position", i.e. the reel-up is designed in such a manner that the final reeling and the threading do not take place in the same position. The reeling cylinder according to the invention can also be coated with a surface material which is softer than the constructional material of the same.
