Definitions

  • the present invention relates to a method and devices for manufacturing gypsum board having 4 thinned edges on their periphery.
  • the technical field of the invention is the field of the manufacture of continuous plasterboard in which two sheets of cardboard, one lower called cream paper, the other upper called gray paper unwind and come to lock in a shaper which is either forming trays or forming rolls, a plaster based hydraulic binder.
  • This composite strip is sheared to length, it goes into a drying oven, it is finally re-sawed to final length before being stacked.
  • Such a method is well known elsewhere and therefore will not be described in itself in more detail in the present description.
  • US-A-2,168,803 discloses a method and a device for the manufacture of plasterboard.
  • US Pat. No. 2,238,017 attempted in 1941 to create a folding allowance for the carton, this invention never gave rise to industrial development, probably because the folding did not withstand the tension of the paper, or the weight of the paper. hydraulic binder.
  • US Pat. No. 2,991,825 attempted 20 years later to make impressions in a As a result of the roll-forming system, it has not been followed by industrial development, certainly because the generated impression is being erased by crushing the hardening strip.
  • the transverse thinning resulting from fingerprints have qualities of surface appearance, shape and strength identical to longitudinal thinning and are well manufactured in a continuous process which proves to be very low cost and very interesting for the industrial and the plasterboard market.
  • the process according to the invention consists first of all in continuously preparing shims (5) at a rapid rate.
  • These shims (5) are extracted from an expandable, flexible, lightweight, inexpensive material.
  • These shims (5) have a thickness of between 1 and 2 mm and a width of between 5 and 20 mm and a length equal to the plate width being produced minus a value of between 0 and 10 cm.
  • these shims (5) will be extracted from a roll (26) of flexible tape (27), cut to length and glued on their upper face.
  • the wedges (5) are in a material having the same expansion to moisture as the cream paper (8) on which it is fixed. It is for example a wedge (5) of paper of the same nature as the cream paper (8), so that the composite strip (45) can expand freely and without being held by the wedge (5) during its hardening.
  • the method according to the invention then consists of sticking these shims (5) under the cream paper (8) in a mandatory zone before the shaper (13) so that they necessarily pass through the latter.
  • the bonding of shims (5), previously prepared, under the cream paper (8) is, according to the method of the invention, a collage on the fly, continuously, and at a fast frequency.
  • the shims (5) are positioned perfectly centered and well perpendicular to the scroll of the cream paper (8).
  • the docking means used to glue these wedges (5) on the fly are such that the cream paper (8) undergoes no deviation or deformation detrimental to the smooth running of the production of gypsum board (44).
  • the method of the invention takes advantage of the means used to dock and glue wedges (5) the fly to roughen the cream paper (8) on both sides of the wedge (5). ) it can be stamping, knurling, pecking, brushing. Thus, the area corresponding to the future transverse thinned (17) will have a better grip on the grout, the mechanical strength of the joint between plasterboard (44) will be greatly improved.
  • the means for bonding the shims (5) on the fly to pre-mark the cream board (8) with two notch lines (11) which are light and parallel to each other. the wedge (5) and at a distance of between 5 and 9 cm from the axis of said wedge (5).
  • This pre-marking of the cream paper (8) in an area which will later be the beginning of transverse thinning (17), will improve the configuration and appearance, these notching lines (11) delimit the rough surface (12) .
  • the method according to the invention then consists in protecting the wedges (5) embarked by the cream paper (8) against the unwanted tearing associated with the apparatuses present between the mixer (1) and the shaper (13), it is suppressed or softened for this in this area all the attachment points and all the salient points (19).
  • a flexible, slippery and wear-resistant guide sheet (42) is applied, between the mixer (1) and the inlet of the shaper (13), this guide web (42) of width greater than the length of the wedges (5), is fixed upstream by a fastener (47) and then left free, this guide web (42) covers all the tools present in the area such as, the table (48), the beaters (18), the cream paper guides (8), without disrupt the effectiveness.
  • Said guide web (42) allows perfect sliding and crossing of shims (5) of the area between the mixer (1) and the shaper (13).
  • the method according to the invention then consists in allowing shims (5) to pass on the one hand the shaper (13) but also to wait for a sufficient time of hardening of the composite strip (45) so that the impression (20) left by the shims (5) side cream paper (8) of the composite strip (45) is permanent and final.
  • the method according to the invention then consists of taking off the shims (5) on the fly and then throw them in a trash can (43), this take-off is indifferently at a point where the curing time previously mentioned is sufficient. It is preferentially the zone (23) between the 2 curing strips (14) and (15) or just before the shears (2).
  • This takeoff consists of coming to remove the wedge (5) with a brush (22), which after removing the wedge (5), fades, so as not to alter the cream paper surface (8).
  • This brush (22) is wedged at an angle to the line and the brush (22) off the shims (5) more effectively.
  • the takeoff is all the easier as the cream paper (8) at this stage of the process becoming wet, it may be necessary energy to remove the wedge (5).
  • the takeoff of the shims (5) is done with jets of compressed air or by burning the shim (5) with suitable burners.
  • the shims (5) are not removed, they remain then stick to the composite strip (45), their low mechanical strength allows without problem a shear cut (2) to the right of the latter said wedges (5) then continue their circuit to be destroyed by sawing at the end of the line plates.
  • the method according to the invention makes it possible to weaken the wedge (5) in its main axis, it can be the flexible band (27) which is thus designed, it can also be a tool that weakens the flexible band (27) in its main axis when preparing holds (5).
  • the method according to the invention consists in the last phase, to cut the composite strip (45) with the shear (2) to the right of the imprints (20) left by the shim (5).
  • Imprints (20) of width between 10 and 18 cm, that is several times greater than the width of the shim (5).
  • the result, at this stage of the process according to the invention, is a gypsum board (44) with at its periphery four thinned edges, two traditional longitudinal thinned (16) and two transverse thinned (17) generated by the method according to the invention.
  • this plasterboard (44) then crosses the dryer, it is sawn to length, and then stacked before joining the stock.
  • the shear cut (2) occurs simultaneously in the cavities (20) and at equal distance from two cavities (20), the plates (44) thus produced have 3 thinned, two longitudinal thinned ( 16) a transverse thinned (17), these 3-thin plates are interesting for particular applications of the market.
  • the shape and the exact dimensions of the shim (5), the enachting lines (11), the machining of the aforementioned ends of the wedge (5) and the adjustment of the tension of the cream paper ( 8) make it possible to control the shape of the imprint (20) as well as its width between 10 and 18 cm, in fact these parameters all influence the shape and size of the imprint (20) left by the wedge (5).
  • the shims (5) are reduced to a single wire, or even two son of a few mm2 section.
  • These threads are either circular or square, the interest of the thread is that it is easily rolled and is very cheap, so the process will have single-wire wedges (52) and double-spaced wedges (55) .
  • the wedges (5) are extracted from a flexible band (27) always with a width of between 5 and 20 mm, but with a thickness reduced to some 1/10 mm, thus more economical and therefore more advantageous for the process.
  • a flexible band (27) always with a width of between 5 and 20 mm, but with a thickness reduced to some 1/10 mm, thus more economical and therefore more advantageous for the process.
  • the pin (58) locally repels the material of the flexible band (27), it takes a height (59), then artificially increasing the thickness of the flexible band (27), the method thus has a wedge (57) ) very economical.
  • the picot wedge (57) is tinged on one or more lengths. According to another variant of the process of the invention tingles the ends of the wedge (57) with a chosen depth and graduality, thus better controlling the configuration of the intersection zone of the transverse thinning (17) and the longitudinal thinning (16)
  • the wedges (5) are in any of the following materials: either paper, plastic, vegetable material, metal or composite material.
  • the shim (5) takes the form of one or two fusible plastic son son, the advantage of this means is to have a material that avoids the sizing phase of the wedge (5) is the wedge "two in one" (56).
  • the shim (5) is extracted from an easily consumable material, such as paper, so that shims (5) can be burned before shears (2) to subtract them from the composite strip ( 45), the other advantage of this variant is to avoid the landfill of the shims (5) after use.
  • the wedges (5) come from a roll (26) of adhesive tape which has the advantage of a good regularity of the gluing of the wedge (5) on the cream paper (8). ) and which exempts us from the glue maker (30) or (60)
  • a roller (26) of a flexible strip (27) of section about 1.5 x 10 mm This roller (26) motorized and relayed by the rollers (28) engages the flexible band (27) on the lower table (29) perpendicular to the flow direction of the cream paper (8). Said lower table (29) being below and away from the cream paper (8).
  • This flexible band (27) is covered, during its movement towards the lower table (29) of a very light film of glue (24) by the glue (30), this flexible band (27) is cut to length by the knife (31) and then becomes wedge (5).
  • This shim (5) is therefore positioned perpendicularly to the direction of unwinding of the cream paper (8) at a distance and under the latter and centered relative thereto by means of the rollers (28) and their associated positioning sensor.
  • the lower table (29) forming part of the translator gluing follower device (6) is launched at the same speed as the cream paper (8) by means of the carriage (70), said carriage (70) being driven by the transmission motor (33), itself associated with an electronics and the pulse sensor (32) .
  • the pulse sensor (32) fixed with respect to the translating glue follower device (6) permanently knows the position of the shims (5). ) with respect to cream paper (8).
  • the lower table (29) is then found at the same speed as the cream paper (8), at this very precise time the lower table (29) makes a movement up and down by means of the cylinders and guides (34) compressing and gluing the shim (5) under the cream paper (8), said cream paper (8) taking support on the compressible support plate (35) itself attached to the upper counter-table (36).
  • the hold (5) thus fixed on the fly is carried by the cream paper (8) without modifying or disrupting the movement.
  • the translator gluing follower device (6) in position "P2" when gluing the shim (5) then returns to its starting position "P1".
  • a new wedge positioning and gluing preparation cycle (5) resumes, a new shim (5) is glued in accordance with the previous wedge (5) a precise interval "P" and so on the cycle is repeated.
  • This interval "P” depends on the length of the plasterboard (44) sought, the longitudinal expansion of the composite strip (45) during its hardening on the curing strips, the over-length required for sawn timber drywall (44) at the line exit.
  • edges of the wedges (5) are rounded, their ends beveled and tapered.
  • the device associated with this variant of the method is a machining tool that is in line with the glue (30) and the knife (31) and which machines the flexible band (27) at the time of its passage and its engagement on the lower table (29).
  • a rough surface (12) and two encapsulation lines (11) are created on either side of the shim (5).
  • Figure 20 shows in more detail how this rough surface (12) and the notching lines (11) of the cream paper (8) on either side of the shim (5).
  • the tool associated with this variant of the method consists of the stamper (37) and counter-stamper (38) attached to the upper counter-table (36) which during the upward movement of the lower table (29) come slightly stamping so mark the cream paper (8).
  • the flexible band (27) of a thickness of some 1/10 mm used to make the shim (5) is tipped in one or more lines in its long direction.
  • the tool associated with this variant is an online tool with the gluing tool (30) and knife (31). This tool has a way of adjusting the pecking depth. This adjustable allows the control of the overall thickness or apparent of the flexible band (27) thus the depth of the transverse thinned (17) sought.
  • Both ends of the wedge (5) are tapered more strongly and gradually to improve the profile of the meeting point of the horizontal thinning (16) with the transverse thinning (17).
  • a rotary gluing follower device (7) provides, as the follower gluing apparatus (6), the functions of preparation, positioning and gluing at a precise interval of the shims (5) under the cream paper (8).
  • FIGS. 4 and 5 show this rotating gluing follower device (7), we discover in these FIGS.
  • the preparation, the positioning of the shims (5) on the lower roller (40) is similar to the preparation of the shims (5) of the translator gluing follower device (6).
  • the rounding of the wedge edges (5), their beveling and end tilting is also done in a similar way to the preparation of wedges (5) of the follower gluing apparatus (6).
  • the shim (5) is prepared, it is under and away from the cream paper (8) and at a rear angle (46) with said cream paper (8).
  • the lower roller (40) and the upper roller (41) driven by the transmission motor (39) adopt the same peripheral speed as the horizontal speed of the cream paper (8).
  • order is given to the cylinders and guides (64) drop and rises to the upper roller (41) thus sticking the shim (5) under the cream paper (8).
  • the wedge (5) thus fixed on the fly is carried by the cream paper (8) without modifying or disturbing the movement of the cream paper (8).
  • the stamper (67) and the stamper counter (68) lightly etch the cream paper (8) to obtain a rough surface (12) and two light necking lines (11), we have already mentioned it: the rough surface will coincide with the transverse thinning (17) and the notching lines (11) will coincide with the transverse thinning start line (17).
  • An alternative to the device according to the invention is to facilitate the passage of shims (5) and their sliding in the area between the mixer (1) and the shaper (13). It is a guide sheet (42) flexible, slippery and resistant to wear, this last quality of wear resistance is necessary because the guide web (42) sees the cream paper (8) and all the wedges (5). Said guide web (42) of width greater than the length of the wedges (5) is held by the fastener (47) upstream of the mixing zone (1) shaper (13), the guide web (42) is centered relative to the scrolling of the cream paper (8) so shims (5), the guide web (42) covers all areas of friction and possible hooking between the mixer (1) and the beginning shaper (13).
  • This guide web (42) covers the table (48), the drummers (18) the salient points (19), the cream paper guides (8) and then protects the wedges against any risk of untimely stall in this zone.
  • a last device takes off the shims (5) to reject them in a bin (43). It is a brush (22) that rotates continuously and is angled relative to the line. This brush is actuated by the jack (25) which raises said brush (22) only during the passage of shims (5).
  • the cylinder (25) is controlled by the cavity sensor (21) and its associated electronics which calculates the rise time as a function of the distance d1 between the cavity sensor (21) and the brush (22) and the speed "V" of the composite strip (45).
