Definitions

  • the present invention relates to a method for securing on each of a plurality of web rolls in a set of web rolls which lie close to or are adjacent to one another and have a common center axis, the trailing end of the web through applying on each of the rolls at least one securing tape which has an adhering coating on a first side, so that the end securing tape is fixed by said first side against the roll and extends over the edge (52) of the trailing end of the web.
  • the invention also relates to an assembly of cooperating devices for the carrying out of the method.
  • the paper is normally made in the form of a web material which has a large width and is wound up in a reeling unit provided after the paper machine or is slit up into a number of smaller rolls in a slitting and winding machine provided after the paper machine.
  • a great number of so called tape dispensers normally at least two dispensers per web roll - in order safely to secure the ends of all those rolls which lie axially side by side in the reeling end or in the slitting and winding machine.
  • the tape dispensers have to be mounted on a common carrier at a distance from one another.
  • JP2001206623 discloses a tape applicator for securing web ends on multiple rolls.
  • Another drawback with the use of conventional tape dispensers is that the length of the tapes in the axial direction of the rolls cannot be adjusted. It will always have a length corresponding to the width of the tape strip. If a particularly strong fixation is desired, therefor, a plurality of tapes have to be provided side by side, which makes the taping operation even more complex and requires manual operations in connection with the readjustment of the dispensers. It is an object of the present invention to address the above complex of problems. This and other objects can be achieved therein that the invention is characterized by what is stated the appending claims.
  • the invention it will be possible to allocate the tapes with great accuracy completely digitally at desired places on the web rolls. In principle an infinitely variable allocation can be achieved. According to the invention it is also possible to choose a desired size of the tapes digitally in the axial direction of the web rolls. An adjustable pattern of the tapes which shall be distributed on the web rolls can be achieved without any physical readjustment of tape dispensers. According to one aspect of the invention, only a single tape dispenser is employed, but on the other hand, according to a preferred embodiment of the invention, the width of the tape strip in that dispenser is substantially wider than the width of the tape strips in those tape dispensers which conventionally are used according to the conventional technique.
  • the width may be as large as the length of those tapes is, which are torn off from the conventional tape dispensers which are used in conventional systems for securing the ends of web rolls in the paper manufacturing industry.
  • a single roll of tape of the said kind which may be used according to the invention, therefore represents an amount of tapes which corresponds to quite a number of tape rolls of the type used in conventional systems.
  • this single but large tape roll is used up, it may, according to an aspect of the invention, be replaced by a new, equal roll of tape, while the web material is being wound up in the reeling end of the paper making machine or in a slitting and winding machine.
  • the change of a roll of adhesive tape therefore does not cause any loss of production.
  • the invention is developed for the purpose of satisfying demands in the paper manufacturing industry, but its field of use is not restricted to that field. Its principles can be applied within many branches where web materials are manufactured, treated, converted and/or used, whether they consist of paper, paper board, non-woven material, plastic, aluminum foils, composite materials, or any other material which can be reeled to the shape of rolls, the trailing ends of which shall be secured by means of adhering tapes.
  • those end securing tapes which shall be applied first are transferred from a tape dispenser to a tape conveyor such that they are caused to lie with their opposite, second side against said conveyor at a distance from one another on the conveyor corresponding to the desired distances between the securing tapes on the web rolls, respectively, that they are temporarily retained on the conveyor as the conveyor then is moved towards the web rolls with the adhering first side facing the web rolls each tape being directed against that place on the rolls where the respective tape shall be applied, that all the tapes are brought into contact with their respective roll and are fixed to it on said respective place, and that the conveyor then is moved from the rolls and from the tapes, which remain fixed to the rolls because said first side of the tapes has a larger adhesive strength to the rolls than the opposite, second side has to the conveyor.
  • the tapes which are used in the method and in the assembly have an adhering coating only on that side which shall be attached to the web rolls in order to secure their ends.
  • both sides may have adhering coatings.
  • the method and the assembly then are adapted to this circumstance.
  • the surface of the conveyor against which the tapes temporarily shall be brought in that case may have been afforded features which prevent non-desired adherence, i.e. have release-features. It is, however, understood that this is a complication which can be avoided by using tapes which have an adhering coating on one side only.
  • a conceivable variant also is to use tapes which have a certain amount of, but essentially lower, adhering capacity on that side which shall be brought against the conveyor surface than the tapes have on that opposite side which shall be brought into contact with the rolls of web material.
  • a machine frame in the reeling end is designated 1.
  • two cylinders 2, 3 are mounted in bearings 4, 5 on two bases 6, 7, which form foundation blocks for a pair of gables 8, 9 in the machine frame 1.
  • a transversal beam 10 extends between and connect the upper portions of gables 8, 9.
  • a number of web rolls 11 which have different width and whose ends 50, Fig. 3 , shall be secured, rest on the cylinders 2, 3.
  • the cylinders 2, 3 are provided such that they can be rotated, conveniently by means of a motor 20 for each cylinder.
  • the size of the tape in the example will yet be the same as the size of the tapes which conventionally are used in the field, i.e. 50 x 250 mm. However it is possible according to the invention, if that would be desired, to produce also wider tapes, e.g. tapes with the size 100 x 250 mm, simply by cutting off a 100 mm long piece of tape from the roll of adhesive tape 15.
  • the dispenser 13 can be moved in the vertical direction by means of motion means, generally designated 19, which may be of a conventional type, between an upper working position, Fig.
  • the tape has an adhering coating only on that side which shall face those end portions of web material which shall be secured. If the web material is paper, the tape also consists of paper or other material which can be dissolved in connection with recycling in a paper mill. In other cases, the tape is made of a material suitable in the case.
  • the box girder 22 has a perforated bottom 26, Fig. 6 , and one of its ends, defined as the front end, 27, Fig. 1 , Fig. 4 , extends to nearly close to the dispenser 13, separated from the dispenser only by a short gap 29, Fig. 4 .
  • Fig. 1 - Fig. 4 shows the box girder in its loading position, that is in the position where it receives tapes 28 from the dispenser 13 at the same level as where the dispenser is located and is oriented such that a slot-shaped feeding out opening 30 in the dispenser 13 is on the same level as the bottom surface of the conveyor belt 23, Fig. 3 , Fig. 4 .
  • the driving motor 24 for the conveyor belt 23 is provided at the rear end of the box girder and drives the conveyor belt via a not shown driving roll in a chamber 31 in said rear end.
  • Said chamber 31 is separated by a partition wall 32 (indicated by dashed lines on the exterior of the box girder) from the main part of the box girder, where said perforated bottom is located.
  • the conveyor belt's driving roll in the chamber 31 may be coated with friction rubber, or may other conventional or specially designed means be provided in order to ensure a safe grip against the conveyor belt and hence a non-slip coupling between the driving roll and the conveyor belt.
  • the driving motor 24 may be provided in or outside the chamber 31, as well as not shown means for maintaining the conveyor belt stretched. In the drawings, however, the driving motor 24 is placed on the outside.
  • the one set of motion members 25a, Fig. 1 now will be described with reference to Fig.5 in a view from below to the left in Fig. 1 .
  • the second set of motion members 25a is identically but mirrorwise designed.
  • the box girder 22, which constitutes the framework of the conveyor 14, and the conveyor belt are shown cut off in the drawing.
  • the motion members include an elongated, wide and plate-shaped slide 40 which extends obliquely upwards-downwards at the same angle of inclination as the intended direction of movement of the conveyor 14 to and fro the web rolls 11.
  • One side 40a of the slide 40 is flat and faces the corresponding slide in the second set of motion members 25b.
  • slide 40 On the opposite side 40b of slide 40 there are provided two pairs of parallel recesses or grooves 41a' and 41a", and 41b' and 41b", respectively, which match two pairs of corresponding rails 42a' and 42a", and 42b' and 42b", respectively, on a guide 38.
  • the two pairs of rails on the guide 38 clutch the two rail- shaped male portions 42" and 42''' which are formed between the grooves 41a' and 41a", and 41b' and 41b", respectively, on the slide.
  • the guide 38 is fixedly mounted on, or forms an integrated part of a bracket 38a, which is fixedly mounted on the machine frame 1.
  • Driving means in said members 25a consist of an electrical motor 45 mounted on the bracket 38a, and a toothed drive belt 45a, which extends about half the circumference of a toothed drive wheel 45b on the driving axis of the motor 45, the teeth of which match the teeth of the drive belt 45 a.
  • the toothed drive belt 45a extends along the whole length of the guide 40. It is recessed in a central groove in the guide and is fastened in the two ends of the guide.
  • the bracket 38a and the motor 45 are protected by a cover 39, which has been removed in Fig. 5 in order to visualize the driving members under the cover.
  • the ruler/rulers is/are provided simultaneously to be moved down against a portion 28a of the tapes 28 which extends beyond the rear edge of the box girder 22, and for a fraction of a second press that portion 28a against the web rolls, so that the tapes initially stick with their adhesive underside to the web material, whereupon the ruler/rulers are brought back to their resting position as shown in Fig.6 .
  • a number of pneumatic actuators 56b are provided for the movements of the ruler/rulers, suspended by and connected via hinges/hangers 58 which extend downwards from an elongated, horizontal carrier 59 which is secured on the rear side 22b of the box girder 22.
  • the further devices 57 which shall complete the application and also minimize formation of wrinkles in connection with the application, include a series of rolls 57a. Said rolls are carried by bent arms 57b, which are pivotally connected to the same hangers 58 which carry the said first devices 56, and are pressed by means of springs 57c against the web rolls 11 and successively also against the tapes and the web ends 50.
  • the box girder 22 may have a considerable length. In the case when the invention shall be applied in the paper manufacturing industry, the length may exceed ten meters. In order to prevent any unacceptably large deflection, the box girder therefor should have a low dead weight and an adequate bending rigidity, particularly in the vertical direction. It may also be reinforced by an exterior or, as is shown in Fig. 6 , by an interior, perforated framework 60.
  • the process for the manufacturing of paper is computerized to a high degree. This is true also as far as those units are concerned, which are provided in direct connection to the reeling end or the slitting and winding machine.
  • the control unit which is responsible for controlling the automatic application of the tapes.
  • information is stored about the diameter of the rolls 11 of paper/web material, the width of each of them, how many tapes that shall be attached on each of them, where the tapes shall be placed, and the distance between them.
  • the process for securing the ends of the paper web on the finished rolls is initiated already when the paper is being processed in the reeling end or in the slitting and winding machine of the paper manufacturing machine.
  • the tape dispenser 13 and the tape conveyor 14 then are in their charging positions far above the levels which the finished rolls later on shall occupy, Fig. 1 , Fig. 3 .
  • the conveyor belt 23 is moved at a low, constant rate about the box girder 22 during this phase.
  • a pulse transducer transmits a signal to the electromagnetically operated cutter in the tape dispenser 13 to cut off a piece of tape from the roll of adhesive tape 15, such as the tape 28a, Fig.
  • the tape conveyor 14 with the on its underside releasably adhering tapes is moved obliquely downwards towards the web ends 50 on the rolls 11, more specifically towards the edges 52 of said ends 50, by means of the motion members 25a and 25b.
  • the tape conveyor 14 now has been brought to the position illustrated in Fig. 6 .
  • the ruler/rulers 56a then are quickly brought down against the sticking out portions 28a of the tapes 28 until contact with the roller 11 at a distance inside the edge 52 of the web ends 50, causing the projecting portions 28a of all the tapes to contact its respective web end 50 simultaneously, whereupon they are quickly returned.
  • the web rolls 11 then are rotated in the clock- wise direction with reference to Fig. 6 . The direction is also indicated by an arrow in the drawing.
  • the tape dispenser 13 which is employed in the above described example contains a roll of adhering tape 15 which represents a large volume of tapes. But even that volume is eventually ended and has to be replaced, which is illustrated in Fig. 8 .
  • the dispenser 13 thus is moved down by means of an elevator 19 from its upper working position, Fig. 1 , to the lower tape charging position at a level above the floor which is a comfortable working level for the staff who shall do that job.
  • the elevator 19 can be designed in numerous ways according to conventional technique, i.e. as a screw conveyor, or by means of elements similar to those which are employed in the aggregate of motion members 25a, 25b for the linear movements of conveyor 14/box girder 22, and shall not be described more in detail. In the lower position a quick change of tape roll can be done, whereupon the dispenser 13 is lifted up to its working position.
