Definitions

  • the present invention relates primarily to a method for packaging plaster boards by covering two or more edge surfaces from two or more plaster boards with a tape, either fully or partically.
  • the invention obtains particular application in packaging two or more plaster boards by covering adjacent transversal edge surfaces of said plaster boards with a tape, whose width exceeds the full thickness of the boards to be packaged, such as to enable one part or fraction of the tape to cover the boards edge surfaces and further enable two parts of the tape to cover and adhere to each of the board surface regions, which extends along said board edge surface and which are located adjacent thereto.
  • the invention also relates to an arrangement of an apparatus, intended for carrying out the inventive method, comprising means for covering, either fully or partially, two or more edge surfaces of two or more sheets of plaster board with a tape, preferably a paper tape, having a width which exceeds the full thickness of the board composite intended for packaging, such that a first centered surface part or fraction of the tape covers the edge surfaces of said board composite, and that two further tape surface parts or fractions can be fastened on to a outer respective board surface region located adjacent a respective edge surface of one of said boards.
  • a tape preferably a paper tape
  • the tape is unwound from a tape storage reel as the edge surfaces of the boards to be packaged pass thereby.
  • the tape is precoated on one side thereof with a latent adhesive layer, which is normally moistened and is centered in relation to said edge surfaces and then folded over outer board surface regions extending adjacent said transverse board edge surfaces, with the aid of known folding devices, whereafter the tape is cut adjacent the defining surface of the boards, or at the start and finish of said edge surface.
  • Said strip is preferably scored before folding so as to give a straight or regular edge.
  • the reinforced means can be formed from a flat strip and attached to the marginal edge of the board by bending or rolling operations and suitable secured against accidental removal from the board.
  • a further technical problem in this regard is one of enabling the full width of the tape to be folded around the edge surfaces of the boards along two mutually parallel fold lines, by subjecting the tape to a simultaneous and uniform folding movement along the whole of its longitudinal extension.
  • Another technical problem resides in the provision of conditions which will enable the tape to be advanced, while dry, to a position adjacent the edge surfaces to be covered, and to be cut in this position to a given length, and the cutted length to be coated with an adhesive layer in readiness for folding said tape about said edge surfaces.
  • an associated technical problem is one of ensuring that the tape can be advanced readily without risk of adhesive or tape fastening to elements or components of the tape advancing device.
  • Another technical problem is one of providing conditions, with the aid of simple means, which will ensure that adhesive-coated tape of given length will not fasten to apparatus components, e.g. tape advancing devices, in the event of an interuption in the board manufacturing process.
  • a technical problem resides in the ability to orient a prepared length of tape in a registered position and to activate the tape adhesive, e.g. by moistening the adhesive, so that the tape is ready for use when the board is located in a position corresponding to said registered position.
  • Another technical problem is one of extending considerably the length of time during which the adhesive-coated tape is pressed against the board surfaces, without encroaching upon the rate of board manufacture.
  • Another technical problem is one of providing conditions, with the aid of simple means, whereby the suction boxes or other suitable means are able to urge the tape against said board surface regions so as to establish a strong adhesive bond between the tape and board.
  • a method and an arrangement for packaging two or more plaster boards by covering the edge surfaces, either fully or partially, of two or more sheets of plaster board with a tape, which has a width greater than the combined thickness of the edge surfaces.
  • One part of said tape covers said edge surfaces and further parts of the tape are fastened to board surface regions, that extend adjacent said edge surfaces.
  • the method comprises the sequence of:
  • the arrangement comprises:
  • the advantages primarily characteristic of a method and arrangement according to the present invention reside in the possibilities of applying tape along the edge surfaces of sheets of plaster board to be package together with the aid of said tape, in a single operation and in a stationary position without decreasing the production rate, and in the possibilities of enabling the tape to be positioned more precisely in both the longitudinal and transverse direction.
  • a further advantage resides in improved adhesion between tape and board, as a result of a longer press period, and in a reduced risk of pleating or snarling of the tape.
  • Plaster board is manufactured in continuous lengths by mixing together calcinated gypsum material, essentially hemihydrated or semihydrated sulphate of calcium, a filler and/or an additive material, and water.
  • calcinated gypsum material essentially hemihydrated or semihydrated sulphate of calcium
  • a filler and/or an additive material a filler and/or an additive material
  • water a filler and/or an additive material
  • the slurry is spread conventionally onto a web which is passed through rolls so as to impart a given thickness to the board, after which the board is passed through a given length of travel in order to enable the requisite chemical reactions to take place.
  • the slurry is first spread between two lengths of paper board or card-board prior to being dried in a drying plant herefor, these lengths ultimately forming the front and rear faces of the finished composite board.
  • Figure 1 shows in plan view two sheets of plaster-board 1 and 2 in fully overlapping relationship and located downstream of the drying section, with the rear side of one board 1 being clearly shown and the other board 2 being covered by board 1 and therefore not visible in the Figure.
  • the rear sides of the board face away from one another, whereas the front or fine sides face toward one another.
  • the thickness of the board is determined in the filling process, by the apparatus and paper board used.
  • the plaster board is cut into lengths, slightly over size, and stacked in batches to be dried.
  • the board lengths, hereinafter referred to as sheets, are then placed in pairs, two-and-two, with the front or fine surfaces of each pair facing towards one another.
  • the plaster board sheets 1 and 2 are then cut to a given length in a cutter 3, thereby to form a transverse edge surface 4 on the one sheet 1 and a corresponding transverse edge surface 5 on the underlying sheet 2.
  • each of the cut edges of respective sheets 1, 2 is covered by tape 6,which is wound on a bobbin 7 and extends over a roll 8 and is passed therefrom through a device 9 operative either in applying an adhesive coating to one surface of the tape or in activating an adhesive coating previously applied to said surface.
  • a further roll 10 urges the tape against the edge surfaces 4, 5, so that part of the tape will lie against said edge surfaces, while further rolls 11, 11′ located downstream of the roll 10, on respective sides of the plaster-board sheet, press further parts of the tape against board surface regions that extend along said edge surfaces adjacent thereto.
  • Figure 1 shows the application of tape 6 to solely the visible edge surface 4 of the sheet 1.
  • the apparatus used herefor is shown in a highly simplified manner.
  • That part of the tape 6 which is intended to cover the edge surfaces 4, 5 is referrenced 6a, whereas those parts of the tape which are intended to cover the board regions 12, 13 that extend adjacent said edge surfaces 4, 5 are referenced 6b and 6c respectively.
  • the tape 6 extending between the mutually adjacent sheets 1 and 1′ is severed by cutting means 14, so as to enable the sheets to be packed in pairs with severed tape.
  • Figure 2 illustrates an arrangement of apparatus according to the invention for covering either fully or partially, the edge surfaces of two or more sheets of plaster board, normally two, with tape, preferably paper tape, the width of which exceeds the combined thickness of said mutually superimposed edge surfaces, such that a first centered tape part 6a will cover and optionally adhere to the edge surfaces 4, 5, and such that two further tape parts 6b, 6c will cover, but primarily adhere to sheet surface regions 12, 13 which extend adjacent the edge surface of respective sheets 1, 2.
  • tape preferably paper tape
  • the inventive arrangement illustrated in Figure 2 includes a first bobbin or reel 20 having wound thereon a tear band or tear wire 21, and a second bobbin or reel 22 upon which the tape 6 is stored.
  • the tape 6 and the tear band 21 are passed through a pair of feed rolls 23 and 24 and a guide 25 to a holding device 26, which comprises an upper U-shaped rail 27 and a lower U-shaped rail 28.
  • the longitudinal extension of the rails is substantially equal to the length or width of the intended edge surface.
  • the tape 6 is advanced through the guide 25, via the feed rolls 23, 24, into the holding device 26 until the edge surface 6a′ of the tape 6 breaks a light beam 30 projected by a light-emitting source 31 onto a light-receiving device 32, which is arranged to produce a signal when said light beam is broken.
  • the signal produced by the light-receiving device 32 is delivered to known circuit means (not shown) which stop the rolls 23 and 24 in response to said signal.
  • the tape 6 is then cut at the location referenced 14 in Figure 1 to a length which is equal to or which exceeds by a well defined extent the length of the intended edge surface 4, 5 of the plaster board.
  • the tape can be cut to a length which is equal to or slightly less than the length of the plaster-board. It is preferred, however, to cut the tape to a length which is some centimetres longer than the length of the edge surface to be covered and for the excess length to project beyond said edge surface.
  • the tape 6 is preferably cut to a length which is equal to or slightly longer than the length of the intended edge surface 4, 5.
  • the cut tape length 6 is positioned adjacent the edge surface of the board by positioning means in the form of the holder 26, operative in positioning an imaginary centre line of the tape 6 adjacent to and parallel with an imaginary centre line 45 on the edge surfaces of the board.
  • the first centred part 6a of the tape is able to cover the edge surfaces 4, 5.
  • the aforesaid displacement means is also operative in further displacing the tape and/or the edge surfaces in a manner such as to enable the two further parts 6b, 6c of the tape to be folded into abutment with a respective surface region 12, 13 of the board by means of folding means, in the form of suction boxes, said displacement and folding means co-acting with one another in a manner to fold the tape simultaneously along two mutually parallel fold lines 35, 36, so as to effect a simultaneous and uniform folding movement along the full longitudinal extension of the tape length 6.
  • the configuration of the rails 27 and 28 conforms more favourably to the thickness of the tape 6, and the rails 27, 28 will preferably be positioned closer to the suction boxes 37, 38.
  • the size of the channel in the rails 27 and 28 is such as to accomodate almost the full thickness of the tape 6, this channel preferably having a width which is smaller than 1 mm.
  • the illustrated arrangement includes lifting means which when the cut tape length 6 is located between the rails 27 and 28 lifts the rail 27 up, as shown in section B of Figure 3, therewith causing a sub-pressure to be applied to the suction box 37, such as to bring the tape part 6b into co-action with the suction box 27 via a hole 37a or a line of holes 37a.
  • the rail 28 is then displaced, via said lifting means, away from the tape 6 and a subpressure is similarly applied to the suction box 38 so that the tape part 6b is brought into co-action with the suction box 38 via a hole 38a or a line of such holes.
  • the cut tape length 6 and the edge surfaces 4, 5 are arranged to co-act with one another via said displacement means, to an extend such that the suction boxes 37, 38 pass over the said surface regions of the sheets of plaster board 1, 2.
  • suction boxes 37, 38 are arranged to press the tape 6 against said board surface regions 12, 13 during said displacement, such as to generate greater frictional forces than those generated solely by the suction forces between the tape parts 6b and 6c and the suction boxes, so as to stretch the tape 6 uniformly over the edge surfaces of the board.
  • the lifting means has the form of a motor 41 which drives a spindle 42 for raising and lowering the rail 27, and a motor 43 which drives a spindle 44 for raising and lowering the rail 28, such as to register the centre line of the cut tape length 6 with the centre lne 45 of the sheets of plaster-board 1, 2.
  • Figure 4 also illustrates schematically displacement means 46 operative in enabling the tape 6 and the edge surfaces 4, 5 to be displaced towards and away from one another, into and out of co-action with one another, so that a first centered tape part 6a covers and optionally adheres to the edge surfaces 4, 5, this being effected by displacing the suction boxes 37, 38 towards the plaster-boards 1 and 2. Said displacement is also used to effect the return movement.
  • the folding means comprises the suction boxes 37, 38, which have been given a suitable curvature 37b and 38b.
  • the illustrated arrangement of apparatus enables the two further tape parts 6b, 6c to be folded into abutment with a respective board surface region 12, 13, said displacement and Folding means co-acting to fold the tape simultaneously along two mutually parallel fold lines in the aforedescribed manner.
  • the suction box 37 can be raised and lowered by means of the device 15 illustrated schematically in Figure 4, thereby to enable the distance between the mutually opposing surfaces of the suction boxes 37 and 38 to be adjusted to the prevailing thickness of two superimposed sheets of plaster-board.
  • the roll 40 is sprayed with water from a valve 51, and can be moved up and down along the tape 6 with said tape held firmly by the suction boxes 37 and 38, by means of a pneumatic piston-cylinder device 52.
  • FIGS 3 and 4 illustrate the arrangement in side view.
  • the length of the suction boxes 37 and 38 should conform to the length of the rails 27 and 28, which means that the illustrated holes 37a and 38a in reality consist of one or more rows of suction orifices extending along the whole suction box. It will be understood that each suction box may be divided into sections, so that the subpressure, through a row of holes 37a, will act, e.g., from the centre of the suction boxes towards the end parts thereof, thereby to have a stretching effect on the cut tape length 6.
  • the tape 6 may be cut to a length at which, when applied to the edge surfaces 4, 5, part of the tape will extend beyond the defining surfaces of said edge surfaces by from 2-5 cm, so as to provide a grip for the tear wire or tear band when wishing to separate the mutually joined plaster-board sheets.
  • suction boxes are positioned parallel with the edge surfaces in the illustrated embodiment, and are therewith intended to be displaced over the sheets of plaster board while retaining their position, it also lies within the scope of the invention to incline the suction boxes slightly, so that the tape is applied progressively onto the edge surfaces to be covered.
  • one suction box 55 which is arranged adjacent the tape 6 and intended to be moved to the right and under pressure hold the tape 6 in registered position.
  • a further movement towards the right and the tape 6 is in co-action with the transverse edges of the two plater boards 1 and 2.
