Definitions
- the present invention relates to apparatus for use with a rotating glue roll for applying glue to a sheet of material, and to a method of applying glue.
- the invention relates in particular, but not exclusively, to apparatus for applying glue to the flute tips of a single-faced sheet of corrugated paper board prior to the single-faced sheet being combined with a continuous second cover sheet for facing the other side of the fluted sheet, and to a method of such manufacture.
- Corrugated paper board conventionally consists of two opposing cover sheets or liners and an intermediate sheet which is fluted or corrugated, the three layers being secured together by adhesive.
- the manufacturing process includes corrugating a fluting sheet; gluing this to a first cover sheet; and then gluing a second cover sheet to the single-faced board already produced. Sometimes two or more fluted layers are included, interspersed with cover sheets.
- a gluing machine applies adhesive to the flute tips by a rotating glue applicator roll.
- the glue applicator roll turns at about the speed of the single-faced sheet, while the lower portion of the rotating roll picks up glue from a suitable reservoir. Glue is thus transferred from the rotating glue roll to the flute tips of the single-faced sheet.
- pressure must be applied to the back, or faced side, of the single-faced sheet. It is known in the art to use a rotating pressure roll positioned opposite the glue roll to ensure contact between the flute tips of the single-faced sheet and the glue roll.
- US-A-5,129,980 Sissons
- US-A-5,248,362 Sissons
- the contact bar includes an elongate frame mounted opposite to and in spaced apart relation from the rotating glue roll.
- a series of shoes are pivotally connected to the frame and depend therefrom defining a predetermined clearance from the outer surface of the rotating glue roll.
- FR-A-1455170 discloses apparatus for applying adhesive to corrugated card by an applicator cylinder rotating in a reservoir, with a pressure cylinder urging the corrugated card against the application cylinder.
- a separate controllable cylinder spaced upstream of the pressure cylinder and applicator cylinder bears against the card on the same side as the pressure cylinder.
- the controllable cylinder is movable during operation of the apparatus to vary the arc of contact of the card with the applicator cylinder while the glue is being applied.
- GB-A-925036 discloses apparatus for applying adhesive to component parts of corrugated board, and more particularly to apparatus for applying adhesive to the tips of the flutes of a single faced corrugated board prior to the application of a second face in the production of a double faced corrugated board.
- apparatus for applying glue to a sheet of material comprising a glue roll for applying glue to a sheet of material passing over the glue roll; an elongate frame positioned across the direction of movement of the sheet over the glue roll; contact means mounted on the frame for urging the sheet into contact with the glue roll; and an elongate rotary device mounted on the frame substantially parallel to the elongate frame and spaced therefrom upstream relative to the direction of movement of the sheet, the elongate rotary assembly being positioned so as to bear against the sheet for tensioning the sheet before it passes to the glue roll.
- the contact means for urging the sheet into contact with the glue roll consists of a riding roll above the glue roll. The purpose of the disclosure is said to be to enable the nip pressure exerted by the riding roll to remain unaffected by variations in the thickness of the board.
- apparatus for applying glue to a sheet of material comprising a glue roll for applying glue to a sheet of material passing over the glue roll; an elongate frame positioned across the direction of movement of the sheet over the glue roll; contact means mounted on the frame for urging the sheet into contact with the glue roll; and an elongate rotary device mounted on the frame substantially parallel to the elongate frame and spaced therefrom upstream relative to the direction of movement of the sheet, the elongate rotary device being positioned so as to bear against the sheet for tensioning the sheet before it passes to the glue roll; characterised in that the elongate rotary device is positioned so as to bear against the sheet on the same side as the contact means.
- the invention has particular application where the apparatus is adapted for the manufacture of corrugated paper board, the apparatus comprising a single-faced assembly for supplying a continuous single-faced corrugated paper sheet comprising a fluted sheet and a first cover sheet on one side of the fluted sheet, and a gluing machine including said glue roll arranged to apply glue to the flute tips of the single-faced sheet for subsequent combination with a continuous second cover sheet for facing the other side of the fluted sheet.
- the apparatus may include a positioning device mounted on the frame for adjusting the position of the rotary device relative to the elongate frame so as to predetermine the amount of the sheet in contact with the glue roll when passing over the glue roll.
- the positioning device comprises means for moving the axis of the rotary device relative to the frame in a direction transverse to the direction in which the rotary device is spaced from the elongate frame.
- a positioning device embodying the invention allows variation in the length of the arc of the sheet which is in contact with the glue roll as the sheet passes around the glue roll.
- the positioning device may comprise at each end of the rotary device a support for the rotary device which is movably mounted on the frame and drive means coupled between the frame and the support for moving the support relative to the frame.
- the drive means may comprise a pneumatic piston and cylinder arrangement.
- the positioning device includes at each end of the rotary device an adjustable stop mounted on the the frame to determine the operating position of the support.
- the rotary device may comprise a series of rollers spaced apart across the elongate rotary device.
- the term roller includes an elongate roller having a width greater than its radius, and also includes a relatively narrow roller forming a wheel having a width less than its radius.
- the rollers are independently rotatably mounted on a shaft extending across the elongate rotary device, and conveniently there may be provided means for varying the spacing of the rollers across the elongate rotary assembly.
- the contact means may comprise a series of shoes arranged in side-by-side relationship across the elongate contact means, for example generally as disclosed in the aforesaid patent US-A-5,248,362.
- each shoe may have a contact portion for contacting the sheet and a pivot portion pivotally connected to the frame, the contact portion being spaced from the pivot portion in a first direction and the rotary device being spaced from the contact means in a second direction generally opposite to the first direction.
- a method of applying glue to a sheet of material comprising passing a sheet of material over a rotating glue roll; urging the sheet into contact with the glue roll as it passes over the glue roll by contact means mounted on an elongate frame positioned across the direction of movement of the sheet over the glue roll; and tensioning the sheet by an elongate rotary device mounted on said elongate frame substantially parallel to the elongate frame and spaced therefrom upstream relative to the direction of movement of the sheet, the elongate rotary device being positioned so as to bear against the sheet before it passes to the glue roll.
- such a method is characterised in that the elongate rotary device bears against the sheet on the same side as the contact means.
- a source 12 of a first cover sheet or liner 13, and a source 9 of a fluting sheet 10 feed the liner 13 and fluting sheet 10 to be combined in a machine 14 which effects the steps of corrugating the fluting sheet 10, to form a corrugated sheet 15 and gluing to it the liner 13.
- the machine 14 is called a single-facer and produces at its output a single-faced sheet of corrugated paper board 16 which is fed onto a conveyor belt 17.
- These components are usually known as the "B" assembly.
- Figure 1 also shows a second single-facer 14', usually known as the "C” assembly, for producing a similar single-faced sheet of corrugated paper board 16' supplied to a second conveyor 17'.
- the single-faced sheet 16 is produced from one liner or cover sheet and one fluting sheet.
- the source 12 is shown as having two supply rolls, and the same is shown for source 9. One roll is used at a time in each source. When one roll expires the second roll is spliced in to provide a continuous sheet.
- the fluting sheet 10 is fed into the nip of heated corrugating rolls (not shown).
- a corn based starch reservoir applies glue to the tip of the flutes of the newly formed fluted paper which is combined with the liner sheets 13 and the various sheets are stuck together by the adhesive.
- the newly formed single-faced web 16 is then transferred to the overhead conveyor 17 from whence it is passed to a preheating and gluing section shown in Figure 2.
- the single faced web 16 is passed to a triplex pre-heater 18, thence to a duplex glue machine 19, and thence to a heating section shown in Figure 3.
- the triplex pre-heater 18 has three drums 20 and 20', and 21.
- the single-faced web 16 is passed around the underside of the drum 20 and pre-heated prior to passing to the glue machine 19.
- a second cover sheet or liner 22 from a source (not shown) of continuous liner sheet passes into the pre-heater 18 and around the underside of the drum 21, and thence to the glue machine 19.
- the second single-faced web 16' passes in similar manner around the drum 20'.
- a reservoir of glue 23 is applied by a glue roll 24 to the single-faced web 16.
- the second liner or cover sheet 22 merely passes through the bottom of the glue machine 19 without being glued, and is then joined to the single-faced web 16 in the heating section of the double-facer to be described with reference to Figure 3.
- the sheet 16 is urged against the glue roll 24 by a contact means 31, which may be any of the known prior art contact means, but preferably is a sliding contact device as set out in the said patent US-A-5,248,362.
- Figure 3 the first part of an assembly 25 known as a double-facer, which part is the heating section 30 thereof having a main frame 32.
- the second, traction, section of the double-facer is not shown but is disclosed fully in our co-pending patent application GB-A-2,321,652.
- a roll 26, opposed by a pressure platen receives between the two the single-faced corrugated paper board sheet 16 and the second cover sheet 22.
- the sheets 16 and 22 are compressed together and glued by the adhesive which has been applied to the tips of the flutes of the sheet 16 by the glue roll 24.
- the sheets 16 and 22 are combined together to form a double-faced corrugated paper board sheet 27 which is then passed through the heating section 30 of the double-facer 25, consisting in this example of eighteen thermo bars 28 mounted on a supporting frame 29.
- the double-facer 25 includes a series of steam heated tables 34 over which the lower cover 22 and single faced web 16 are passed. The heat at approximately 180° gels the glue and causes a bond that sticks the single-faced web 16 to the lower cover sheet 22. The web is then transferred to a traction section of the apparatus.
- the contact means 31 consists of a contact bar comprising an elongate frame 32 extending across the paper sheet 16 which is travelling in the direction indicated at A, the frame 32 being formed principally by a rectangular tube. As described in the previous specification US-A-5,248,362, the frame 32 extends substantially across the entire width of the rotating glue roll 24.
- a series of side-by-side contact shoes 33 are pivotally connected to the frame 32 and depend therefrom. A slight gap is left between adjacent shoes 33.
- Each of the contact shoes 33 includes a contact portion 34 and a pivot portion 35 connected by pivot 36 to a bracket 37 of the frame 32.
- the contact surface of the contact portion 34 is preferably concave in shape approximating to the curvature of the outer surface of the glue roll 24.
- Each shoe 33 has a biasing means, such as a compressed coil spring 38 to urge the contact portion 34 in a direction away from the frame 32 towards the single-faced sheet 16.
- the pressure applied by the shoe contact surface may be adjusted by providing the spring 38 with a desired spring force.
- Adjustment means may be provided to set a predetermined clearance between the surface of the glue roll 24 and the contact surface of the contact portion 34.
- the adjustment means includes an adjustment bolt 40 and nut 41 secured to an angle bracket 42 secured to the bracket 37. The end of the adjustment bolt 40 bears against the upper surface of each shoe 35 at the end thereof opposite the compressed coil spring 38.
- the passage of the single-faced sheet 16 between the glue roll 24 and the shoe contact surface will cause deflection of the springs 38 thereby causing a backing pressure to be applied to the single-faced sheet 16 by the shoe contact portions 34.
- the clearance may be adjusted to accommodate slightly thinner or thicker single-faced sheets.
- the setting for the distance between the glue roll and the contact shoe may be typically 1.0mm.
- the area of the sheet 16 which contacts an arc of the glue roll 24 is determined by the position of a separate wrapping roll 43 in the glue machine 19, together with the position of the leading roll 26 in the double-facer 25. Adjustment of the area in contact with the glue roll 24 of the sheet 16, is thus difficult to arrange, and also tensioning of the sheet 16 before contacting the glue roll 24 is difficult to adjust.
- tensioning apparatus 48 comprising an elongate rotary device 44 mounted on the frame 32 substantially parallel to the elongate frame and spaced therefrom upstream relative to the direction of movement of the sheet 16.
- the rotary assembly 44 is positioned so as to bear against the sheet 16 for tensioning the sheet before it passes to the glue roll 24.
- the rotary device 44 consists of a series of wheels 45 spaced apart across the rotary device 44.
- the wheels 45 are independently rotatably mounted on a shaft 46 for rotation in the direction indicated by the arrow B.
- the direction of rotation of the glue roll is indicated in Figure 5 at C, and the direction of movement of the sheet is indicated by arrow A.
- FIG 6 there is shown the general location of the contact bar 31 and the tensioning apparatus 48 within the glue machine 19.
- the wrap roll 43 shown previously in Figure 4 is shown inside the glue machine, and a corresponding wrap roll 49 is provided for the second cover sheet 22 passing through the bottom of the glue machine 19, together with a further roll 50.
- the elongate rotary devices 44 is spaced from the frame 32, by being mounted at each end on two mounting plates 60 which protrude from the frame 32 rearwardly relative to the direction of movement of the sheet 16.
- FIG 7 there is shown in detail a positioning device 51, also shown in Figures 5 and 6, for varying the position of the rotary device 44 relative to the elongate frame 32 so as to vary the amount of the sheet 16 which is in contact with the glue roll when passing over the glue roll.
- the positioning device 51 comprises at each end of the shaft 46 a drive means 52 coupled between the frame 32 and a shaft support 47 in which the shaft is mounted.
- the drive means may comprise a pneumatic arrangement of piston 53 and cylinder 54.
- each end of the shaft 46 protrudes beyond the shaft support 47, through a slot 55 in a back plate 56 and rests, in its most downward position, on an angle limit stop 57.
- Operation of the drive means 52 allows raising and lowering of the bearing support 47, guided by the distal end of the shaft 46 moving up and down in the slot 55.
- each wheel 45 is mounted on a bearing 58 secured to the shaft 46 by wheel bushes which are fixedly mounted on the shaft 46.
- the individual wheels 45 can rotate independently on the shaft 46.
- the positions of the wheels 45 across the rotary device can be adjusted by means of collars 59.
- Each collar may be secured to the shaft 46 by set screws (not shown).
- the wheels 45 may be made of urethane with a shure hardness of 90.
- the shaft 46 may be raised or lowered relative to the elongate frame 32 by operation of the piston and cylinder arrangement of the drive means 52.
- the shaft 46 is shown in a relatively raised position, with the piston 53 extended to one quarter of its stroke.
- the shaft 46 is positioned at a lower position relative to the frame 32, the piston 53 being extended to one half of its stroke.
- the shaft 46 is at a yet lower position relative to the frame 32, with the shaft 53 extended to three quarters of its stroke.
- the sheet 16 will wrap around a greater arc of the glue roll 24, than in the case of Figure 8a.
- movement of the rotary tensioning device 44 can achieve variation in the tension applied to the sheet 16, and also variation in the area of the sheet which comes in contact with the glue roll.
- the frame 32 is mounted on two arms (not shown) one on each side of the glue roll, and these arms are moveable under pneumatic, electrical or hydraulic controls.
- the controls lift the contact bar clear of the glue roll.
- the controls lower the contact bar to a position having a predetermined spacing from the glue applicator roll. Because the tensioning apparatus 48 provided by the rotary device 44 is mounted on the elongate frame 32 of the contact bar, the whole tension unit 48 is lifted and lowered with the contact bar.
- the tensioner is arranged to tension the single-faced paper sheet prior to the application of the glue to the tips of the flute of that sheet.
- the tensioner is arranged to pre-determine the amount of the single-faced sheet that touches the glue applicator roll. This can be done by adjusting the stroke of the cylinders by mechanical limit stops.
- the mechanical limit stop provided by the angle limit stop 57 can be adjusted to one of three levels, and secured in place by bolts 63 which can be optionally placed in holes 64 in the end plate 56.
- the objective of the angle limit stop 57 is to limit the stroke of the cylinder rod and consequently the movement of the shaft 46 and wheels 45.
- By adjustment of the position of the angle limit stop it is possible to predetermine exactly the amount of contact the paper sheet has with the glue applicator roll. It has been found that, in the absence of the rotary device of the present invention, there are a number of variables in the positioning of components, and the line or path followed by the paper sheet through the machine. It is found that the angle of the paper entering the contact bar will vary from machine to machine. Also at each plant the height of the glue rolls relative to the height of the first steam chest in the heating section 30 varies, causing bonding problems. Also, as shown in Figure 2 at the glue machine 19, the upper glue applicator roll 24' has a distinctly different angle for the paper leaving the unit, in comparison with the lower glue applicator roll 24.
- the positioning device in the embodiment shown has three positions for the angle limit stop, although more or less positions may be provided.
- the positioning device 51 it is possible to predetermine exactly the amount of contact the paper has with the glue application roll.
- the entrance angle of the paper sheet By predetermining the entrance angle of the paper sheet to be the same, it is possible to standardise the paper line leaving the surface of the glue roll.
- the tensioning rotary device, together with the positioning device creates a paper line or path which will give a surface contact area chosen by the operator. This is especially important when, for example, three glue applicator rolls are used in one gluing machine.
- the functions of the pneumatic cylinders in the embodiment shown are two-fold.
- the rotary tensioning device also lifts under the power of the two pneumatic cylinders of the positioning device 51. This gives the operator easier access to feed the paper sheet 16 between the glue applicator roll 24 and the contact bar 31.
- the contact bar is lowered into its running position, and then subsequently the rotary tensioning device is lowered into its running position to tension the paper and obtain the correct paper line.
- the movement of the rotary tensioning device is achieved by operating a separate pneumatic hand operated valve having settings of raise and lower. If the rotary tensioning were to be kept permanently in its operating position, i.e.
- wear shim 66 there may be provided between the mounting plates 60 and the frame 32 a wear shim 66, at each end of the contact bar.
- the wear shim 66 has apertures 67, to allow fitting around bolts 66 which secure the mounting plates 60 to the frame 32.
- the function of the shim is as follows.
- the shims 66 can be removed.
- the angle limit stop can then be lowered to its lower position and the entrance angle and paper line can be retained to its original setting. This gives the user of the overall paper making machine time to restock the wheels for replacement.
- the shims are replaced again in the unit.
- the thickness of the shim may be 10mm.
