Definitions
- the present invention relates to a single-sided machine for the production of corrugated cardboard strips and a line of manufacturing comprising such a machine.
- corrugated cardboard For the manufacture of corrugated cardboard, generally used a machine known as single face to form corrugations on a first strip of paper and then after gluing the ridges of ripples, apply a strip of cover paper over them to give what is called a strip of single-sided corrugated cardboard.
- These single-sided machines generally include two cylinders fluted, an upper fluted cylinder and a lower fluted cylinder.
- the first strip of paper goes around part of the circumference of the upper grooved cylinder before being introduced into the area between the upper grooved cylinder and the cylinder lower grooved. This wavy strip then wraps around a part of the circumference of the lower grooved cylinder where the crests of ripples will be glued.
- a strip of paper cover will be applied, with pressure, on the crests of the undulations, previously glued, using a smooth cylinder, called a smooth press, around a part of the circumference of which the strip of winding cover paper.
- This corrugated cardboard manufacturing operation single-sided is effected by means of grooved cylinders and a cylinder smooth heated.
- the upper and lower grooved cylinders are in general arranged so as to be able to keep the corrugated strip applied in the grooves of the cylinders.
- Auxiliary heating devices are also provided for maintain the strip of single-sided corrugated cardboard thus produced at a sufficient temperature to ensure adequate drying of the adhesive that we deposited on the ridges ripples.
- the single-sided machines described in the various publications mentioned above are intended to produce cardboard single-sided corrugated at production speeds of around 300m / min and more. At these speeds, various problems arise for the manufacturer.
- One of these problems caused in particular by the speeds of high rotation of the different cylinders, lies in the appearance significant vibrations generating a sound level of very high functioning requiring important anti-noise protections.
- Another problem, from the same source, is wear and tear important fluted cylinders.
- An additional problem, always coming from the same source lies in the impossibility of using strips of corrugated paper as well as strips of paper relatively low grammage coverage due to the risk of rupture, by excessive traction and pressure on them during their passage between the lower grooved cylinder and the smooth cylinder of the press smooth.
- Another important problem also caused by high operating speeds, refers to the heat transfer time the strips of paper to be processed.
- a corrugated line is intended to produce corrugated cardboard in different forms, i.e. to produce single-sided corrugated cardboard, double-sided corrugated cardboard side, which is obtained by gluing together two strips of corrugated cardboard single sided, and possibly triple corrugated or quadruple sided.
- single-sided corrugated cardboard double-sided corrugated cardboard side
- two strips of corrugated cardboard single sided we use several single sided machines, one machine per single-sided tape, and the strips are superimposed by gluing produced to obtain the desired type of corrugated board.
- the strips of corrugated cardboard is then cut to the required size, and stacked to be issued to their user.
- the strip of single-sided corrugated cardboard emerging from a single-sided machine is treated individually when you want to obtain single-sided corrugated cardboard.
- the corrugations of the cardboard strip single-sided corrugated coming out of the single-sided machine are glued and covered with a second cover strip by means of a gluer, they are then dried in a drying device, then grooved and split longitudinally to the desired lateral format by a machine commonly called machine gun.
- a machine gun commonly called machine gun.
- slitting longitudinal of the cardboard strip produces two dimensional strips which are then separated and directed, on two levels, in direction of a cross cutter which will cut transversely each of the strips of cardboard in the desired longitudinal format.
- the plaques of corrugated cardboard thus obtained are then sent to two separate stackers, one for one of the plate sizes and the other for the second format of plates.
- the object of the present invention is to remedy the aforementioned drawbacks.
- the object of the invention is constituted by a machine single sided in accordance with claim 1 as well as the use of such a machine in a cardboard production line corrugated.
- Figure 1 is a schematic view of a first version a single-sided machine 1 which includes two lateral frames 2, 3 comprising bearings for supporting an upper grooved cylinder 4, a intermediate grooved cylinder 5 and a lower grooved cylinder 6.
- the upper grooved cylinder 4 is arranged to be able to apply, by means of a vaccine, the ripples formed in the meshing zone 7 between the upper grooved cylinder 4 and the intermediate grooved cylinder 5 against its grooves, this on at least part of its circumference.
- the lower grooved cylinder 6 is also arranged, like the cylinder upper grooved 4, in order to be able to apply, by means of a vaccine, the corrugations, formed in the meshing zone 8 between the cylinder lower grooved 6 and the intermediate grooved cylinder 5, against its grooves, this over at least part of its circumference.
- a first strip of paper waving 9 taking a coil 10 is conducted, after passing around deflection rollers 11, 12, between the lower grooved cylinder 6 and the intermediate grooved cylinder 5 in the engagement zone 8.
- a cover strip 14 taken from a reel 15 will be applied against the tips of the grooves by means of a smooth press 16.
- the smooth press shown here is a smooth press well known to machine builders. It is well understood that this smooth press could be of another type, also well known to machine builders, for example a smooth press using metal belts instead of a smooth cylinder.
- This strip of corrugated cardboard 19 is then routed towards the organs following the production line passing around the rollers return 20, 21, 22, 23 and 24.
- Return rollers 22 and 23 are located in a pit 36 arranged in the foundation supporting the machine single sided 1.
- Return rollers 20 to 23 are smooth rollers whereas roller 24 is a special roller, generally made of material plastic, called "non crush roll" by specialists.
- This roll 24 is so chosen to avoid crushing the corrugations of the cardboard strip corrugated 19 which are, in this place in contact with its circumference then that around the other return rollers 20 to 23, it is the paper strip cover 14 which is in contact with their circumference thus avoiding direct crushing of the grooves. It should be noted that, if necessary, the various idler rollers used could also be heated.
- a second strip of corrugating paper 25, taken from a coil 26 is driven, after passing around idler rollers 11, 12, between the upper grooved cylinder 4 and the grooved cylinder intermediate 5 in the meshing zone 7.
- This second strip of corrugating paper 25, having been corrugated during its passage in the zone meshing 7, wraps around part of the circumference of the upper grooved cylinder 4, part of the circumference in which the tips of the corrugations will be glued using a device sizing 26, which in this embodiment is a sizing device with a bubbler roller associated with an applicator roller.
- a device sizing 26 which in this embodiment is a sizing device with a bubbler roller associated with an applicator roller.
- the sizing device 13 for the strip of corrugating paper 9 can be made in the same way as the sizing device 26 for the second strip of corrugating paper 25.
- This corrugated strip 30 is then routed to the following organs of the line manufacturing by passing around a deflection roller 33.
- the roller reference 33 is a smooth roller. It should be noted that, if necessary, the various used idler rollers could also be heated.
- Figure 2 is a schematic view of a second version of a single-sided machine 1 in which the grooved cylinder intermediate 37 is much smaller in diameter than the cylinder intermediate grooved 5 in Figure 1.
- This choice is dictated by the desire to decrease in the best proportions the number of splines in engagement in mesh zones 7 and 8 so as to reduce stresses mechanical undergone by the strip of paper to be corrugated.
- the theory followed to come up with the solution of using a grooved cylinder small diameter intermediate is well known to manufacturers of machines that seek to decrease the length of the labyrinth formed by grooves of the cylinders in their engagement zone.
- the second strip of cover paper 25 passes around a roll of return 38 so as to guide it to the engagement zone 7 between the upper grooved cylinder 4 and the intermediate cylinder 37.
- Figure 3 is a schematic view, in the form of a block diagram, of a first version of a cardboard production line single-sided corrugated using a single-sided machine 1 identical to those previously described in Figures 1 or 2.
- the reference numbers 10, 15, 26 and 28 are relate to the paper reels.
- Reference numbers 9 and 27 are relate to the strips of paper to be corrugated.
- Reference numbers 14 and 25 relate to the strips of cover paper and the numbers references 19 and 30 relate to the strips of corrugated cardboard leaving the single-sided machine 1.
- the corrugated cardboard strips 19 and 30, represented graphically at 47 and 48 are routed to a preheater 39, which also receives strips of paper cover 40 and 41 taken from coils 42 and 43. These different strips 19, 30, 40 and 41 are then introduced into a gluing machine 44 in which the corrugated strips 19 and 30 will each be covered with a cover strip 40, respectively 41 to form two separate strips of single-sided corrugated cardboard 45 and 46 shown graphically at 49 and 50.
- each strip of single-sided corrugated cardboard 45 and 46 will be separated longitudinally to produce four strips 56, 57, 58, 59 of possibly different widths corresponding to one of the coordinates, width, desired format for cardboard plates corrugated harvested at the exit of the production line.
- Another advantage of the solution which has just been described resides in the fact that a speed reduction of a third compared to the speed conventional machines, for example, would already provide acceptable operating conditions and would allow an increase from production line production to values never before achieved.

These two bands 70 and 71 are then transferred to the cross cutter 55 two-stage. The band of double-sided corrugated cardboard 66 will be cut to length desired by the cross cutter 55. At the exit of the cross cutter 55, we obtain double-sided corrugated cardboard, of two formats different, on two passage levels 60 and 61. Finally, the passage level 60 double-sided corrugated sheets are stacked in stacker 64 and those of passage level 61 are stacked in a second stacker 65.

These four bands are then transferred to a two-stage cross cutter 55, respectively 55a. Single-sided corrugated cardboard strips 56 to 59 will be cut to the length of the format desired by the cross cutter. At the exit of the cross cutter we obtain cardboard plates corrugated single sided, in four different formats, on four levels of passage 60, 60a, 61 and 61a.
