Definitions

  • the present invention relates to a baler in a so-called single-sided corrugated cardboard manufacturing machine sheet of fluting paper whose crests are glued on a first cover sheet.
  • This intermediate box is also called single-sided.
  • this first carton is either directly assembled to a second sheet of cover paper outside to give a cardboard called double-sided, either before assembled with a second single-sided carton to obtain a final carton called double-double.
  • the groove paper is preheated and humidified before passing between two fluted cylinders which are heated with steam.
  • the groove thus formed is maintained against the lower grooved cylinder by means of combs, or a system of the external environment, or a vacuum system of the interior of the lower grooved cylinder, the surface of which has slots of communication.
  • a glue roller bathed in a glue tank deposits a predetermined amount of glue on the ridges of the grooves.
  • the paper also preheated cover and the groove paper are finally pressure assembled between the lower grooved cylinder and a device support called a smoothing press.
  • the most commonly used baler is consisting of a smooth cylinder parallel to the lower grooved cylinder against which it is in support.
  • the contact surface is greater than that between two grooves.
  • the baler is consisting of a cross member held at its ends by branches lower levers, and the active side of which faces the grooved cylinder lower is arched in portion of cylinder of equal radius, even slightly higher than that of the grooved cylinder.
  • This cross member can also be hollow for the heating steam passage. However, less balanced and less rigid that a cylinder, such a cross member can twist and warp so that the application pressure is no longer uniform over the entire length of the cylinder grooved. The quality of the gluing is then greatly altered.
  • the baler consists of a endless belt passing between upper and lower rollers located parallel and close to the lower grooved cylinder, respectively at mid-height and below. This strip is thus in contact with the cylinder grooved on a quarter of the lower periphery.
  • This endless band can be a thin strip of steel or a carpet of copper, cotton or fiber threads synthetic.
  • the pressure applied to the sheets by this heald press depends on the tension applied to the endless belt. It suits then to provide a complex mechanical spacing device for one of the rolls of the endless belt relative to each other, and this with possibility adjusting this large voltage to a specific value. Again, he it is impossible to guarantee the maintenance of a constant tension throughout the width of the endless belt, therefore a uniform application pressure of the cover sheet against the flute sheet.
  • the object of the present invention is a heald press in a more efficient single-sided corrugated machine that is to say that constantly applies pressure over time uniform across the width of a cover sheet joined to a groove sheet passing around the lower grooved cylinder.
  • the baler must allow adjustment to a precise pressure value of application in order to obtain an effective setting of the adhesive without thereby damage the leaves.
  • the design of this baler must be relatively simple to ensure operational reliability in the time and ease of implementation and maintenance at cost reasonable.
  • each device includes its pad with a arched surface covering a plurality of grooves and its actuator pressure application
  • each of these support devices can effectively trigger the glue and correctly assemble the papers exerting lower pressure in its assigned area longer but very precise, therefore less damaging to the grooved cylinder and cardboard.
  • the use of a transverse series of separately adjustable devices ensures reliable application of common pressure uniform across the width of the carton.
  • Each device comprising a lighter force application structure than in the case of a cylinder or of a single sleeper, can make faster and better corrections controlled to achieve pressure application exactly predetermined.
  • such a series of small support devices reacts more quickly exactly to possible transverse variations or longitudinal thickness of one or both sheets.
  • the bearing surface of the pads is covered or is made of a smooth and wear-resistant material such as a strip of polished metal: copper or stainless steel, or such as a synthetic material by example that marketed under the name Teflon.
  • a smooth and wear-resistant material such as a strip of polished metal: copper or stainless steel, or such as a synthetic material by example that marketed under the name Teflon.
  • the support device comprises a plate carrying a shoe, this plate being pivotally mounted according to its edge lower or higher than the frame of the machine, the other edge opposite being connected by a first hinge to a linear actuator, such that a cylinder, itself connected to the frame of the machine by a second hinge, this actuator pushing the plate and the shoe against the cylinder grooved or removing it. If the skate is mounted on the plate close to its pivot, then this plate acts as a lever amplifying the force exerted by the actuator which can then safely be undersized for considerations saving.
  • the shoe is a block of elastomer whose arched support surface is covered with a smooth and resistant material wear.
  • the periphery of the pad and its bearing surface can be square or rectangular oriented in the direction of movement of the papers, these forms being easily achievable. If we want to avoid any risk of maculature on the assembled cardboard, we can consider a diamond shape, the pads being nested thanks to an arrangement along two lines superimposed; or an alternately oval and thinned shape along the series.
  • the support device includes a pad in the form of a band held at one of its ends by a cross member parallel to the cylinder and fixed to the frame of the machine, and in its other end by a movable cross member secured to a first end of a lever pivoting in the middle and whose opposite opposite end is connected by a first hinge to a linear actuator, such as a jack, itself connected to the frame of the machine by a second hinge, this actuator lifting or lowering the first end of the lever, which stiffens or loosens the band.
  • a linear actuator such as a jack
  • the strip can be metallic in copper or in polished stainless steel, or woven from metallic fibers, natural or synthetic, such as a mixture of carbon fibers and Teflon.
  • This strip may have a slight longitudinal elasticity. The structure of this device is particularly simple therefore reliable.
  • the support device includes a pad with prominent lower and upper edges on which are fixed the two ends of a curved strip, this shoe being mounted in pivoting according to its upper or lower edge on a first half of a arm, the other edge resting on this same half of the arm through a elastic means, such as a spring or an elastomer block, the end of the other half of the arm being pivotally attached to the frame of the machine, the first half of the arm being connected by a first hinge to a underlying linear actuator, such as a jack, itself connected to the frame of the machine by a second hinge, this actuator pushing this first half arm, therefore the shoe, against the grooved cylinder or removing it.
  • a elastic means such as a spring or an elastomer block
  • the braking force of the cardboard induced by the friction forces generated at the level of the heddle press is compensated for by the fact that the cardboard is pulled downstream of the grooved cylinder and the heald press by a tractor device, in particular by a grille composed of a cylinder tractor around which the cardboard is wrapped by contact with its paper cover on at least a third of the circumference, and a support roll radially flexible in contact with the fluting paper.
  • the cover paper is brought to the heald press by an upstream cylinder preheating and guiding defining, with the downstream tractor cylinder, a cover paper feed angle, i.e. the angle at top of the portion of grooved cylinder with which this paper cover is in contact, greater than 30 °. So the tension in the cover paper creates additional application pressure.
  • the bearing surface of the pads is arcuate according to an angle at the top corresponding to the paper feed angle blanket.
  • the width of the bearing surface is preferably between 100 and 200 mm.
  • Figure 1 is schematically illustrated in perspective a so-called single-sided manufacturing machine intended for the manufacture of a carton 6 also called single-sided consisting of the assembly of a paper groove 2 and a cover paper 4. More specifically, the groove 2 arrives from above and travels a first U-turn around a upper grooved cylinder 10. This paper 2 is grooved at the engagement of the upper cylinder 10 with a second grooved cylinder lower 12. The flute paper 2 'thus formed is held against this lower cylinder 12 during a second downward U-turn by a device not illustrated can be combs, an external overpressure created in a coating box or an internal depression in the grooved cylinder lower with radial openings allowing the suction of paper. During this second half-turn, a glue roller 13 illustrated in FIGS.
  • a cover paper 4 is preheated during its rotation around a cylinder 14 then guided towards the lower part of the lower grooved cylinder 12 of so as to arrive well parallel to the 2 'flute paper against which it (4 ') is finally tackled.
  • a heald press formed, according to the invention a lateral series of support groups 30 applies pressure predetermined necessary and sufficient on the one hand to burst the glue cells and on the other hand firmly hold the two papers one against the other while taking the glue threads attaching the papers one to the other. More particularly according to the invention, the outgoing carton 6 is drawn in downstream by a grille made up of a traction cylinder 16 surmounted by a flexible backing roller 18.
  • the cardboard 6 is thus wound up with its 4 more solid cover around the upper half of the traction cylinder 16.
  • the contact pressure between this carton and this traction cylinder is reinforced by the support of the roller 18 acting against the fluting paper more fragile.
  • This support roller includes a connected elastomer periphery in its central shaft by a series of longitudinal radial fins also made of elastomer, the cross section of which is oblique or even curved.
  • the baler is composed of a series of support groups 30 arranged side by side along the lower downstream part of the grooved cylinder 12.
  • Each support group 30 first comprises a plate 36 whose lower edge is rotatably mounted by a pivot 38 on the same first cross member secured to the frame of the machine.
  • the upper edges of the plates 36 are each connected to a second common cross member secured to the machine frame by means of a associated individual cylinder 40.
  • Each cylinder is connected to the lower crossmember by a hinge 44 and at the upper edge of its associated tray by a second hinge 42.
  • each plate 36 carries a shoe 32 whose base fixed against the plate has a rectangular shape whose length is parallel to the direction of travel of cardboard 6.
  • the face 34 located opposite the grooved cylinder 12 is curved into a portion of a cylinder of substantially equal radius, or even slightly higher than that of this cylinder 12.
  • the active bearing surface 34 pressing the cover paper 4 'against the groove paper 2' is preferably a surface with a low coefficient of friction and also a high resistance to wear.
  • this surface can be metallic, polished or a layer of synthetic material such as Teflon.
  • the skate body can be metallic, we prefer an elastomer block with relative elasticity to absorb any vibration residual due to speed or accidental thickness variations of either of the papers.
  • the active surfaces 34 rectangular side-by-side together define a support area in which the pressure can be strong enough to trigger the glue but moderate enough not to damage the cardboard or the fluting of the lower cylinder 12. If you fear the formation of possible streaks on the cardboard cover sheet due to possible differences momentary pressure from one support group to another, then we can consider skates whose shape includes oblique lateral sides making the transition from one skate to another spread over a certain width. For example, we can consider pads 35 in the form of diamonds and arranged along two nested lines, or pads 33 side by side with curved side edges: these pads alternately having a tapering oval and concave shape. We can also consider a S-shaped skate edge
  • FIG. 2 is illustrated from the side a second embodiment of support groups 50.
  • This embodiment is based on a pad taking the shape of a curved rectangular band 58 oriented in the direction of scrolling papers.
  • the lower end of the strip 58 is attached to a first fixed cross member 56 of width equal to that of the strip.
  • the upper end of the strip is fixed to a mobile cross member 54 because it is attached to the end of a first branch of a lever 52 pivoting around a axis located at the end of an upright 51.
  • the opposite end of the second leg of the lever is connected to the machine frame by an articulated jack 40 on two hinges: a lower 44 fixed to the ground and an upper 42 fixed to the lever.
  • the lever branch carrying the cross member may have a length between half and a quarter, preferably a third of the length total of the lever so as to obtain a force amplification effect applied by the jack 40 to the strip 58 to stiffen it against the cylinder grooved lower 12.
  • crosspieces 54 and 56 have surfaces rounded upper ends making the ends of the strip 58 curved towards outside.
  • the length of the strip 58 is substantially equal at the tear-off arc (e) of the contact surface of the cover paper 4 against cylinder 12, as defined by the respective positions of the cylinder preheating and guiding 14 and the traction cylinder 16 relative to the lower grooved cylinder 12.
  • Figure 3 is illustrated a third embodiment of a support group 60 based on an arm 64 movable in rotation around a pivot of upper base 66.
  • the lower half of this arm 64 carries a shoe 61 mounted pivoting around a hinge 65 close to its upper edge, then that its lower edge rests on the arm 64 through an elastic means 63 such as a row of springs or a rubber stop.
  • the upper and lower edges of the shoe 61 are formed by transverse prominences with rounded ends on which the rounded edges are fixed in correspondence with a strip 62 constituting the application surface of the cover paper 4 against the paper of groove 2.
  • the arm 64 is also connected to a cross member of the frame of the machine by a jack 40 articulated on two hinges: a lower 44 and a superior 42.
  • the hinge 42 therefore the point of action of the jack 40, is located substantially in the middle of the pad 61 to push it so balanced against the lower grooved cylinder 12.
  • the application strip 62 of this embodiment, as well as the strip 58 of the previous embodiment, are preferably metallic such as copper or polished steel.
  • these bands can also be woven of metallic threads or fibers or Teflon reinforced with carbon or any other synthetic fiber with a low coefficient of friction and high resistance to wear.
  • the length of the action of the strip 62 is only one fraction between two thirds and three quarters downstream of the angle for covering the cover paper 4 against the cylinder 12 as defined by the relative position of the upstream guide roller 15 and traction cylinder downstream 16 relative to this lower grooved cylinder 12.
  • the bursting glue cells is made at this level by a flexible roller 11, similar to roller 18, and located vertically under the cylinder grooved 12.
  • the pressure applied by the support groups 60 is then established at a fair value sufficient to ensure the proper maintenance of the paper cover 4 against the groove paper 2 during the setting of the glue.
  • the guide cylinder 15 is smaller than the guide cylinder 14 of the previous embodiment of the that preheating is provided by a heating table 17 located at upstream.
  • FIG. 4 illustrates a variant of the embodiment according to Figure 3 also using a series of supports 60 and in which the guide roller 15 and the heating table 17 are replaced by a smooth cylinder 72 according to the state of the art.
  • this smooth cylinder is mounted on bearings 72 movable vertically according to a servo (subject to a co-patent application by the owner), this servo allowing to bring this cylinder 70 close to the cylinder lower grooved 12 at a distance (h) exactly predetermined and regulated.
  • This clearance (h) is established in such a way that the smooth cylinder only sets in contact the preheated cover paper 4 and the flute paper 2 and apply a force just necessary to burst the glue cells, but in any case weak enough not to risk damaging the carton 6 or the splines.
