Definitions

  • the present invention relates to a method for securing on a web roll, or 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.
  • 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 infmetily 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 roll or on the web rolls, respectively, that they are temporarily retained on the conveyor as the conveyor then is moved towards the web roll/web rolls with the adhering first side facing the web roll/web rolls, each tape being directed against that place on the roll/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 roll/rolls and from the tapes, which remain fixed to the roll/rolls because said first side of the tapes has a larger adhesive strength to the roll/rolls than the opposite, second side has to the conveyor.
  • an assembly of cooperating devices which include a tape dispenser provided to feed tapes one by one to an essentially rigid, elongated tape conveyor which has a length at least as long as the distance between the farthest out positioned tapes that shall be applied against the roll/rolls, means provided for placing the tapes on the conveyor with a spacing corresponding with the desired spacing between the tapes when the tapes have been secured on desired places on the web roll/rolls, wherein the conveyor is capable of retaining the tapes when the tapes rest with their second side against the conveyor, which second side is opposite said first side, and wherein a first aggregate of motion members is provided to move the conveyor with said tapes towards said desired places on the web roll/rolls from a starting position at a distance from the web roll/rolls till contact between said first side of the tapes and the roll/rolls on said desired places and then back to the starting position, leaving the tapes behind, secured on said desired places on the web roll/rolls
  • 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.
  • Fig.1 is a perspective view of the rolls of web material, the free or trailing ends of which shall be secured, and the assembly according a preferred embodiment of the invention, which forms part of a slitting machine or reeling end which may be provided in connection to a paper manufacturing machine,
  • Fig. 2 shows the assembly isolated in the same view as in Fig. 1,
  • Fig. 3 shows the assembly according to the invention in a view diametrically opposed to the view of Fig. 2,
  • Fig.4 illustrates, at a larger scale, how a tape dispenser is delivering tapes to a tape conveyor included in the assembly, in the following briefly also called just conveyor
  • Fig.5 shows, also at a larger scale, motion members for moving the conveyor in a linear direction towards and from the web rolls
  • Fig. 6 shows in the same perspective as Fig. 1 a developed embodiment of the conveyor in cross section and motion members for turning the conveyor about a longitudinal centre axis in the final part of the initial application of the tapes on the rolls,
  • Fig. 7 shows the conveyor in its lower position in the final part of the application operation
  • Fig.8 illustrates a method and means which facilitates change of tape dispenser.
  • 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 integrated assembly according to the invention is generally designated 12, Fig. 2. Its main components consist of a tape dispenser 13, a tape conveyor 14, and motion means for the conveyor.
  • the tape dispenser 13 is of a type and has a design which is known per se, but is not of the type and design which conventionally is employed in the present field of use.
  • the main difference is that the roll of adhesive tape 15 in the dispenser 13 is much wider than those tape rolls which conventionally are used in the field. While the latter ones normally have a width in the order of 50 mm, the roll of adhesive tape 15 in the dispenser is several times wider. In the present example it has a width of 250 mm.
  • an essentially shorter piece of tape is cut off in connection with each delivery of tape, e.g.
  • 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 main parts of the conveyor 14 consist of an elongated box girder 22, an endless conveying belt 23 extending about the two ends of the box girder, a driving motor 24 (symbolically shown), for the conveying belt, two sets of aggregates 25a and 25b of motion members for the linear movements of the box girder, and two sets of motion members for turning the box girder about a horizontal center of rotation 37.
  • That side of the box girder 22 which in Fig. 3 and in Fig. 4 is facing the viewer is denominated front side 22a, and its opposite side, Fig. 1, Fig. 2, and Fig. 5, consequently denominated rear side 22b.

  • 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.
  • the interior 35 of the box girder has, as mentioned, a perforated bottom 26 in the region of the main part of the box girder which extends from the partition wall 32, and is connected to a symbolically shown air exhauster 34 via a symbolically shown hose 33, Fig. 6, such that a reduced pressure is maintained in the box girder above the perforated bottom 26.
  • the conveyor belt 23 consists of a high strength material which is permeable to air. It may for example consist of a belt which is perforated by holes lying closely together and is preferably reinforced such that it will have such a high coefficient of elasticity in the longitudinal direction of the belt, such that its elongation can be neglected.

  • the conveyor 14 is connected to the lower ends of the two guides 40, in a mode which is partly illustrated in Fig. 5 but will be shown and explained more in detail in the following. But it should be understood already by what has been shown and explained so far, that the two slides 40, which form part of said sets 25a and 25b of motion members, guided by the guides 38, can be displaced through linear movements, bringing the conveyor 14 with them, to and fro the web rolls by means of the stationary mounted motors 45 (one in each set of motion members 25 a and 25b) and the toothed drive belts 45 a.
  • Each set 36a, 36b of motion members, Fig 3, Fig. 4 and Fig. 6, for turning the box girder 22 about a horizontal axis of rotation 37 comprises the following components in each end of the conveyor 14: a pneumatic actuator 44, a bracket 43 which is stationary mounted on the flat side of 40a of the slide 40, and a short lever 46a in the form of a first arm of a right-angled yoke 46, the second arm 46b of which is secured to the front side 22a of the box girder.
  • the first mentioned arm/lever 46a extends over the upper side of the box girder at athe short distance therefrom, such that passages 51 are formed for the conveyor belt 23 between the arms/levers 46a and the box girder 22.
  • Nose portions 47 of the levers 46a in both ends of the box girder extend a distance beyond the rear side 22b of the box girder.

  • the first part 53a of the axle bar is stationary connected to the flat side of the slide 40, while the levers 46a in the two ends are pivotally connected to the second part 53b of the respective axle bar 53 in a first hole 48 which forms a bearing in the yoke 46 in a region above the front wall 22a of the box girder.
  • the center of the axle bar 53 defines said center of rotation 37.
  • a second hole 49 is provided for the connection of the piston rod of the actuator 56b to the lever 46a.
  • Fig. 6 showS a development of the invention which aims at making the application of the tapes 28 on the web rolls 11 more efficient.
  • the tape conveyor is equipped with first devices 56 for causing an initial application of the tapes 28, and second devices 57 for completing the application. These devices are placed on the rear side 22b of the box girder 22.
  • the first devices include a ruler or a series of rulers 56a, which consist of a metal rail having a thick layer of a plastic material with a low friction coefficient, e.g. Teflon, on its underside.
  • the ruler/rulers 56a extends/extend along the entire part of the box girder 22 which is provided with a perforated bottom.
  • 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 mode according to which the assembly of the invention is intended to operate can be automatized to a high degree. This is particularly true as far the paper manufacturing industry is concerned, the specific demands of which the application in the first place has been developed to satisfy. Within other fields of use, the demand of automatization may not be correspondingly great, or is a high degree of automatization not possible or even desirable, but also in those fields of use the invention may hold out many advantages in connection with manufacturing and/or winding up web material, even if not as obvious as within the paper manufacturing industry. In the following, however, the mode of operation of the invention shall be described as an example of the highly automatized technique which the invention makes possible for securing the ends of web rolls in the paper manufacturing industry.
  • 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 ends 50 shall be secured by means of those tapes 28 which have been distributed in the said desired way on the conveyor belt 23.
  • Information is also stored about where the end of the web material is located, when the tape application process is initiated, as well as information about where the end should be located when the tapes are applied. If the actual is- value does not correspond with the desired should- value, the rolls 11 are rotated a certain angle on the rolls 2,3 by means of the motors 20 until the desired should- value, which is stored in the control unit, has been reached.
  • 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 is turned about its horizontal axis of rotation 37 by means of the aggregation of motion members 36a and 36b for adaptation of the position of the conveyor to the diameter of the rolls 11 , so that the underside of the conveyor belt 23 will be essentially parallel with a tangent to the rolls 11 where the tapes shall be placed.

Abstract

Dans la présente invention, pour la fixation de l'extrémité de bande d'un certain nombre de rouleaux de bande, qui se trouvent les uns à côté des autres ou côte à côte, des rubans qui seront appliqués sur les rouleaux sont transférés d'un distributeur de ruban (13) à un transporteur de ruban (14, 22) de telle sorte que les rubans viendront en contact avec le convoyeur par le biais de leur surface non adhérente à une distance l'un de l'autre correspondant aux distances souhaitées entre les rubans sur le(s) rouleau(x) du matériau en bande. Le transporteur avec les rubans est par la suite déplacé en direction du ou des rouleau(x) de bande, chaque ruban étant dirigé vers cet emplacement sur le(s) rouleau(x) où le ruban doit être appliqué avec un côté adhérent amené en contact avec le rouleau respectif et fixé au rouleau audit emplacement. Le transporteur est ensuite retiré, les rubans restant fixés au(x) rouleau(x) à l'intérieur, car le côté adhérent des rubans possède une plus grande puissance d'adhérence au(x) rouleau(x) que celle du côté non adhérent au transporteur.
