Definitions

  • the present invention relates to a "single-sided" station for a machine for manufacturing corrugated cardboard comprising a frame composed of a base flanked by two side walls between which are installed a lower pressure cylinder and an upper cassette supporting a pair of cylinders stacked grooves.
  • the "single sided" station is located upstream of a corrugated cardboard manufacturing machine.
  • a first sheet of paper is corrugated by passing between two fluted cylinders, an upper and a lower.
  • a sizing cylinder located substantially at the height of the lower fluted cylinder deposits glue on the ridges of the corrugated paper before application of a second facing paper by a pressure cylinder located under the lower fluted cylinder.
  • the cylinders are simply mounted in bearings permanently fixed in the station frame.
  • cassettes containing the pair of grooved cylinders with their bearings and drive motors have been produced for larger machines, cassettes which can then be removed laterally, by rolling them over rails integral with the frame and then on rails belonging to a carriage.
  • a particularly large machine in which a cassette can be mounted in an upper space of the frame to allow lowering, in an orthogonal direction, a second cassette thus allowing a very rapid exchange of the grooved cylinders and thereby a change in the profile of the grooves.
  • Each of the cassettes can also be removed laterally for exchange of the grooved cylinders or for their maintenance.
  • the object of the present invention is to obtain a “single-sided” station with cassettes which is compact and whose design makes it possible to simplify the production in order to reduce the costs accordingly.
  • the design of the structure must be such that the mounting and fixing of the cassettes is rapid and solid, while preserving sufficient spaces for access and maintenance of all the components.
  • the operation of this station must be reliable, that is to say efficient for the production of quality corrugated cardboard, while ensuring flexible operation having a vibration regime of the station which is the lowest. possible.
  • a "single-sided" station for a machine for manufacturing corrugated cardboard comprising a frame composed of a base flanked by two side walls between which are installed a lower pressure cylinder and an upper cassette supporting a pair of fluted cylinders superimposed, characterized in that the lower pressing cylinder is installed in a lower cassette bearing against a seat face and an orthogonal support face are arranged, facing one another, in the front edge of each side walls, said bearing faces of the lower cassette being oriented obliquely to the horizontal and the upper cassette bearing, for its part, against the upper face of the lower cassette as well as against guide faces, parallel to the bearing faces of the lower cassette, extending substantially in the same plane as that defined by the bearing faces i of the lower cassette, said guide faces of the upper cassette also being arranged, facing one another, in the front edge of each of the side walls and in that holding means exert downward traction on anchoring points located on the rear face of the upper cassette to hold the lower and upper cassettes against their seating faces , respective guidance and support
  • a traction exerted downwards by the fixing means simultaneously blocks in a coordinated manner the cassettes supporting the pressure cylinder and the grooved cylinders.
  • the action and feedback forces are notably judiciously distributed along the lines of separation between the cassettes and / or their support surfaces of the frame.
  • the cassettes are designed so that the bearing faces of the lower cassette and the guide faces of the upper cassette extend in two planes, oriented obliquely and offset with respect to each other.
  • bearing faces of the lower cassette and the guide faces of the upper cassette are oriented obliquely at an angle between forty and eighty-five degrees relative to the horizontal.
  • the bearing faces of the lower cassette and the guide faces of the upper cassette are oriented obliquely along an angle of sixty degrees from the horizontal.
  • the means for holding the upper cassette and the lower cassette against their seat, support and guide faces consist of a pair of hydraulic cylinders each arranged on each side of the side walls of the frame, each cylinder being oriented obliquely towards the upper and lower cassettes.
  • the hydraulic cylinders are oriented obliquely at an angle of ten degrees, relative to the vertical, in the direction of the upper and lower cassettes.
  • a hydraulic cylinder is particularly rapid in that it suffices to couple its sliding rod to an anchor point on the rear face of the first cassette and to apply hydraulic pressure.
  • the upper cassette rests, by its upper rear edge, by means of rollers on a cross member of the frame, its lower front edge also being fitted with rollers cooperating with a transverse rail attached to the frame, to allow lateral extraction of said upper cassette by a translational movement.
  • FIG. 1 represents a "single-sided" station 10, the frame 1 of which comprises a base 21 flanked by two side walls 23.
  • the upper 11 and lower 13 grooved cylinders, as well as their respective bearings and drive motors 12 and 14, are mounted inside an upper cassette 50.
  • the lower grooved cylinder 13 has, in this upper cassette 50, a fixed reference position while the position of the upper grooved cylinder 11 and its bearing 12 can be adjusted and / or resiliently pushed against the lower grooved cylinder.
  • the lower pressing cylinder 15, its motor and its bearing 16 are also mounted inside a lower cassette 60 by means making it possible to adjust their position along the axis of the cassette.
  • This lower cassette 60 and this upper cassette 50 are then stacked one on the other in a seat arranged in the front edge of the side walls 23, this seat being substantially oriented towards the inside of the frame.
  • this seat is formed by a seat face 2 and an orthogonal support face 3 arranged, facing one another in the front edge of each of the side walls 23 to receive the cassette.
  • the bearing faces 3 and the guide faces 4 are located in two different planes.
  • the bearing face 3 and the guide face 4 are located in one and the same plane.
  • the bearing faces 3 and the guide faces 4 are oriented obliquely to the horizontal at an angle between forty and eighty five degrees. Preferably, and according to practical tests, this angle will be sixty degrees, the seat faces 2 then making an angle of thirty degrees relative to the horizontal, all the lower presser cylinders 15, lower grooved 13 and upper 11 being aligned along the same straight line parallel to the support 3 and guide 4 faces.
  • the upper cassette 50 comes to bear, by its lower faces, against the upper face 6 of the lower cassette 60, which rests on the seat face 2, while the upper 50 and lower 60 cassettes are supported, respectively, against the guide faces 4 and against the bearing faces 3 arranged in the front part of the side walls 23.
  • Another particularly original characteristic of the invention resides in the way in which these upper 50 and lower 60 cassettes are held together, in the seat, formed by the seat 2, support 3 and guide 4 faces, on the sole by means of a pair of hydraulic cylinders 30, oriented obliquely in the direction of the seat of the cassettes, each arranged near a wall 23 and acting, in traction, between the base 21 and an anchor point 32 located in the rear lower part of the upper cassette 50.
  • This traction effected by the hydraulic cylinders 30 causes the blocking of the lower cassette 60 which finds itself caught between the seat face 2 and the lower contact face of the upper cassette 50.
  • This traction force blocks simultaneously the upper cassette 50 against the upper face of the lower cassette 60 and against the guide face 4.
  • the line of action of the hydraulic cylinder 30 is not entirely vertical but oriented 10 degrees towards the outside of the frame 1 of the station 10, i.e. towards the lower 60 and upper 50 cassettes.
  • the upper edge of the rear face of the cassette 50 is provided with retractable rollers 52 resting on a cross member 27 of the frame 1.
  • rollers 54 can be mounted to cooperate with a transverse rail 28 also attached to the frame 1.
  • FIG. 2 is a detailed view of one of the rollers 52 of the upper part of an upper cassette 50.
  • the roller 52 is mounted on a pin 56 whose eccentric cylindrical part 59 engages in a bore machined in the tab 57 of a support 58 screwed against the face of the upper cassette 50.
  • the pin 56 is tightened against the tab 57 using a washer 61 and a nut 62 secured by a lock nut 63.
  • This arrangement allows, when it is desired to extract the cassette from the single-sided station 10, to rotate the pin 56 so that, under the effect of the eccentric of the eccentric cylindrical part 59, the roller 52, acting on the cross member 27, moves the rear face 64 of the upper cassette 50 away from its guide face 4 and therefore allows the rolling of the upper cassette 50 on the cross member 27 without friction occurring between the rear face 64 of the upper cassette 50 and its guide face 4.
  • the pins 56 When a new upper cassette 50 is put into service, the pins 56 will be retracted by rotation in the opposite direction so that the rear face 64 of the upper cassette 50 comes in contact with its guide face 4.
  • FIG. 3 is a detailed view of one of the rollers 54 of the lower part, ie the front face, of an upper cassette 50.
  • the roller 54 is mounted on a pin 67 welded to a base part 68 screwed against a support 69 itself screwed against the front face 70 of the upper cassette 50.
  • the roller 54 can roll, during the extraction of the upper cassette 50, in a rail 28 of which at least one of the ends is equipped with 'a centering means composed of a rail portion 71 which can be lowered so that its rolling face 72 comes to be located below the rolling face 73 of the rail 28 (see also Figure 4) during the actuation of the holding means.
  • the vertical movement of the rail portion 71 can be ensured by a screw 74 engaging in a thread of a lug 75 integral with the frame 1.
  • the width of the rail portions 71 is defined so that the circumference of the roller 54 come to rest on edges 76 and 77 and that this fact, the upper cassette is centered, laterally in its working position as shown in dashed lines in FIG. 4.
