Definitions

  • the present invention relates and essentially relates to a method for manufacturing a tube, in particular cardboard, by helically winding a strip or several strips of paper, and a machine for implementing this process.
  • the strip of paper or cardboard or the multiple strips of paper or cardboard are partially overlapping and transversely offset with respect to each other and form a sheet.
  • the pitch for winding a strip of paper will depend on the width of said strip of paper, the diameter of the mandrel, and the value of the angle of winding of said strip of paper formed between the direction of unwinding of the paper strip and the longitudinal axis of the fixed mandrel. Therefore, the characteristics of the tube produced depend on the rolled paper, but also on the winding angle of said strip of paper.
  • a manufacturing machine comprising a fixed frame carrying the fixed mandrel and a movable frame making it possible to unwind the strip of paper or the web of strips of paper on the fixed mandrel in a direction of unwinding determined by the desired winding angle.
  • the mobile chassis of the known manufacturing machine which supports in particular a device for unwinding one or more strips of paper, a device for gluing said strips of paper and a system for positioning and guiding the strips of paper to form the sheet, is fixed in an angularly displaceable manner relative to the horizontal longitudinal axis of the mandrel by means of a mechanism (94).
  • the winding angle was adjusted manually, in other words, the direction of unwinding of the paper strips, by manual movement of the movable frame.
  • This process has many drawbacks and requires a painful and imprecise long adjustment (to several degrees) of the winding angle, in particular due to the large dimensions of the mobile chassis.
  • this adjustment was empirical because it was not possible to measure precisely the angle formed between the fictitious axis of pivoting of the movable frame and the longitudinal axis of the mandrel (18), moreover as this adjustment is manual, it required manpower.
  • Document FR-A-2 081 031 reveals a similar teaching.
  • the main object of the present invention is to remedy these drawbacks by proposing a manufacturing method making it possible to measure and precisely control the current winding angle formed between the direction of unwinding of the paper strips and the longitudinal axis of the mandrel. , in addition to automatically controlling the angular displacement of the movable frame to obtain a current winding angle equal to the set or predetermined winding angle.
  • the subject of the invention is a method of manufacturing a tube, in particular cardboard, by helically winding a strip or several strips of paper with partial covering and transversely offset relative to each other by forming a sheet, around a fixed mandrel by rotationally driving the tube in formation, characterized in that it consists in automatically and preferably continuously adjusting the winding angle of said paper strips defined between the common direction of unwinding of said paper strips and the longitudinal axis of said mandrel, by measuring the current winding angle, by comparing the value thus measured of the current winding angle with a set value of said angle, and by controlling an angular displacement of said common direction of unwinding of the strips of paper with respect to the longitudinal axis of the mandrel so that the measured value of said winding angle is equal to the predetermined set value hermit.
  • the above-mentioned sheet of paper web is moved in a rectilinear and reversible manner in a direction perpendicular to the above-mentioned unwinding direction.
  • the paper strip at one end of the ply is wound on the above-mentioned fixed mandrel as close as possible to the mandrel holder, whatever the winding angle chosen so as not to lose space for winding between the device for rotating the forming tube and the mandrel holder.
  • the invention also relates to a machine for manufacturing cardboard tubes by helically winding a strip or several strips of paper with partial covering and transversely offset relative to each other in the form of a sheet, comprising a fixed frame supporting a mandrel. fixed winding of said strips, a system for rotating the tube in formation, a movable frame supporting in particular a device for unwinding one or more strips of paper, a device for gluing said strips of paper and a system for positioning and guiding strips of paper to form said sheet, said movable frame being mounted movable relative to said fixed frame, characterized in that it comprises a device for measuring the current winding angle of the strips of paper on the mandrel emitting a signal, a device for comparing said signal with a set value of the angle of winding of said ply on said fixed mandrel and a device for controlling the angular movement of said movable chassis controlled by said comparison device.
  • the movable chassis is connected to the fixed chassis by a coupling device articulated in rotation about a pivot axis whose fictitious axis cuts perpendicularly the longitudinal axis of the mandrel and is mounted on rolling tracks concentric with said pivot axis, the aforementioned control device ensures the operation of a reversible drive motor of at least one drive wheel of said movable chassis.
  • the axis of the fixed mandrel is substantially horizontal and the aforementioned pivot axis of the coupling of the mobile chassis is substantially vertical.
  • the aforementioned current winding angle measuring device and the aforementioned setpoint display device are potentiometer devices, advantageously the setpoint is expressed in sine of the winding angle.
  • the aforementioned movable chassis is mounted on the aforementioned coupling device so as to be displaceable by rectilinear transverse translation on said coupling device.
  • this fixing of the mobile chassis to its coupling is a screw-nut system actuated by a motor operating in synchronization with the aforementioned motor driving the driving wheel of said mobile chassis.
  • the rotational driving of the tube in. formation is constituted by an endless belt wound around said tube in formation and driven by two drums with vertical axis perpendicular to the longitudinal horizontal axis of the mandrel, carried by a mobile turret possibly in translation parallel to the longitudinal axis of the mandrel and / or movable in angular orientation relative to said longitudinal axis of the mandrel.
  • the angle formed between the horizontal perpendicular to the longitudinal axis of the mandrel and the line passing through the two vertical axes of the aforementioned drums is adjusted to determine the degree of opening or closing of the upper turn of the tube.
  • the cardboard tube manufacturing machine comprises, in a conventional manner, a fixed frame 1, and a movable frame 2 connected to the fixed frame 1 by a coupling system 3 such as a drawbar d 'metal hitch, pivotally mounted about a pivot axis 4 fixed on the fixed frame 1 and whose axis is substantially vertical and perpendicularly cuts the longitudinal x axis of the mandrel 8 which will be described below.
  • a coupling system 3 such as a drawbar d 'metal hitch
  • the mobile chassis is mounted rolling, by means of wheels 7 shown diagrammatically, on rolling tracks or rails 6 arranged concentrically with the pivot axis 4.
  • the movable chassis 2 of the manufacturing machine of the invention advantageously supports a device for unwinding a strip or several strips of paper, a device for gluing one side of these strips of paper and a positioning system and for guiding the paper strip or said paper strips to form a sheet in which the multiple strips partially overlap and are transversely offset with respect to each other.
  • These unwinding and gluing devices as well as the aforementioned positioning and guiding system are very well known in the field of manufacturing cardboard tubes and will therefore not be described in detail, moreover they are not shown in detail in Figure 1 for the sake of clarity thereof.
  • the movable frame 2 comprises fixed on its end 2a not connected to the fixed frame 1, two drive wheels 9 supporting at least one part of said movable chassis by the wheel mounting assembly 10.
  • the driving of these wheels is controlled by a motor 11 in particular an electric motor driving a transmission system 12 with cogwheels and chains, for example.
  • the chassis 2 can be moved around the pivot axis 4 on the rails 6 by rotation of the ⁇ drive wheels 9, driven in movement by the motor 11 with reversible drive.
  • the mobile chassis 2 is fixed to its coupling 3 by a screw-nut system comprising an endless screw 13 and rollers 14 for rolling driven by said screw, allowing rectilinear and transverse translation of the movable chassis 2 with respect to its coupling and therefore relative to the direction of unwinding of the paper web y.
  • the drive of the worm is carried out by a motor 15, for example by a gear motor and a transmission system 16 with cogwheels-chain or pulleys-belt.
  • the fixed frame 1 comprises a mandrel holder 17 preferably fixed at one end of the fixed frame 1, a preferably cylindrical mandrel 8 fixed on the mandrel holder 17 and having a longitudinal axis x preferably substantially horizontal.
  • the mandrel 8 preferably extends over a fairly large length so as to serve as a guide support for the tube 18 of cardboard being formed during its linear movement towards the end of said mandrel 8.
  • the cardboard tube 8 in formation is rotated by an endless belt 19 wound in a simple loop around the tube in formation, preferably with its strands crossed, as illustrated in FIG. belt is driven by two drums 20 with vertical axis carried by a turret 21 movable on the one hand in translation parallel to the fixed axis of the mandrel 8 on for example slides 22 for lateral movement, and on the other hand movable in angular position relative to the longitudinal axis x of the mandrel, so that the straight line z passing through the vertical axes of the drums 20 define an angle 0, in the horizontal plane, with a perpendicular to the longitudinal x axis of the mandrel 8.
  • the angular orientation of the belt 19 and its lateral position relative to the mandrel is adjusted manually or automatically by cranks 23, 24, for example.
  • the means for controlling the angular displacement of the movable frame 2 relative to the fixed frame 1 comprise a measuring device shown schematically at 26 of the angle of winding of the paper around of the mandrel 8 or preferably the angle a defined between the direction y, preferably substantially horizontal, of the unwinding of the paper and the perpendicular in the horizontal plane to the longitudinal X axis of the mandrel 8.
  • This device which is for example a device for potentiometer, emits a signal which is applied to a comparison device 27.
  • This comparison device 27 receives a signal from a display device 28 of a set value of the angle a.
  • this display device 28 is a potentiometer device calibrated in sine value a.
  • the comparison device sends a signal to a control device 29 when the two signals sent respectively by the measuring device 26 and the display device 28 are not identical.
  • the device 29 controls the operation of the motor 11 for driving the drive wheels 9 and the angular displacement of the chassis 2 so that the current angle measured by the measuring device 26 corresponds to the set point value of the angle displayed by the display device 28.
  • the control means 29 will automatically control a movement of the movable frame 2 so that the angle a currently measured by the device 26 becomes equal to the display value. Consequently, by simply displaying the desired angle, the adjustment thereof is carried out automatically and precisely.
  • the movable fixing in transverse rectilinear translation of the chassis 2 on its coupling 3 allows, for example during a change of winding angle, to arrange the strip of paper 25 forming the end of the sheet, as close as possible to the mandrel support 17 to avoid any loss of mandrel length between the mandrel support 17 and the drive belt 19.
  • the translation drive motor 15 operates synchronously, for example by speed variation with the motor 11 for driving the driving wheels 9.
  • the present invention provides a method for adjusting automatically, precisely without manual intervention on the machine, the angle of winding of the paper strips around the fixed mandrel 8, and on the other hand, by adjusting the angle 6, in other words the inclination of the belts relative to the longitudinal axis x of the mandrel the degree of opening or closing of the last turn of paper wound on the tube in formation.
  • the present invention therefore makes it possible to automate the operation of a machine for manufacturing cardboard tubes, and mainly to allow very precise and very rapid adjustment of the angle of winding of the paper around the mandrel, as well as to maintain this constant angle throughout the manufacturing cycle.
  • the movable frame 1 can also support all the elements, devices for shaping strips of paper before they are wound around the fixed mandrel, and moreover that this movable frame can only support the guidance and positions strips of paper before winding to position them in the direction of unwinding Y.
