Definitions

  • the present invention relates to guide devices for strip materials, as well as their applications.
  • Such a guide device generally comprises a guide roller mounted to rotate about its axis on a movable frame, itself supported by a fixed frame, actuating and retaining members being provided for moving and holding the movable frame by compared to the fixed frame.
  • the movable frame supporting the guide roller is mounted so as to be able to oscillate about an axis which can be defined as the intersection of a median plane perpendicular to the axis of the roller with a plane containing the upstream strand of the strip. If the strip moves in a vertical plane, the axis of oscillation of the movable frame and consequently of the guide roller, is then found to be vertical, tangent to the roller and contained in the median plane of the latter.
  • Such an arrangement has a major drawback which lies in too long a reaction time, since it is necessary to move the movable frame and therefore the guide roller over a large amplitude in order to obtain a correction on the strip and a reminder of the latter in centered position. In addition, the correction has no effect on the upstream strand and the regulation of such a device is difficult taking into account this large amplitude of displacement.
  • US Pat. No. 3,109,572 proposes another arrangement in which the movable frame is supported relative to the fixed frame so as to be able to oscillate around an axis also contained in the median plane perpendicular to the axis of the roller but s' extending perpendicular to the plane of the strip, at a certain distance below the axis of the roll.
  • the axis of rotation is therefore horizontal, whereas it was vertical in the first device described.
  • the response time of this second device is much shorter, but in return, it has another drawback which consists in an elongation and a deformation of the strip at its edges, this drawback being particularly serious in the case of thin sheets. , that is to say sheets having a thickness less than about 0.4 mm.
  • this known device results in limiting the speed of the strips to a value which cannot exceed 25 m / nm; still it should be specified that this upper limit is reached only if a manual control is added to the conventional automatic control device.
  • the object of this invention is therefore to provide a guide device for elastoplastic web materials, which does not have any of the drawbacks stated above and which, therefore, offers a sufficiently short response time without causing deformation. inadmissible material passing through the device.
  • the subject of the invention is a device for guiding a strip of elastoplastic material, comprising a guide roller mounted to rotate about its axis on a movable frame, itself supported by a fixed frame, means of actuation and holding being provided to move and maintain the movable frame by approaching the fixed frame, the frame being mounted oscillating around an axis contained in a median plane perpendicular to the axis of the guide roller, device in accordance with that described in US-A 3,109,572, characterized in that said movable frame is mounted oscillating about the axis on at least one bearing surface of the fixed frame and on at least one cylindrical guide surface centered on the axis, said axis being at least approximately tangent to the roller and forming with one and / or the other strand of the strip an angle of between 5 and 30 ° .
  • the guide device shown in the drawings can be placed, for example, in a strip heat treatment oven, or else in an accumulator.
  • This device as shown in Fig.1 comprises a fixed frame 1 made in any suitable manner and which comprises at its upper part a frame 2 delimiting an inclined plane 3 forming with the horizontal an angle a between 5 and 30 ° and for example around 10 ° in a particular embodiment.
  • a movable frame 10 also comprising a frame 11 and provided with two bearing supports 12 between which is rotatably mounted a guide roller 13 carried by a shaft 14.
  • This roller is rotatable about its axis XX and can be driven in rotation from a motor 15.
  • On the roller 13 passes a strip 20 whose two upstream 21 and downstream 22 strands are here vertical and that it is a question of maintaining in position centered on the roller.
  • the movable frame is mounted on the fixed frame so as to be able to oscillate about an axis YY perpendicular to the inclined plane 3 defined by the fixed frame, tangent to the roller 13 on the side of the latter which is attacked by the upstream strand 21 of the strip, and finally contained in the median plane of the roller, perpendicular to the axis XX.
  • the means for supporting the movable frame on the fixed frame comprise three bearing assemblies 31, 32, 33 of which two 31.32 are arranged at the upper part of the frame 2 and the other 33 at the part lower of this same frame.
  • Each bearing assembly comprises a block 4 secured to the fixed frame and which delimits a support surface 5 and a cylindrical guide surface 6 centered on the axis YY, as well as a foot 40 carried by the movable frame and also delimiting it a bearing surface 41 and a cylindrical guide surface42. These surfaces are made or coated with an appropriate anti-friction material.
  • the guide surfaces associated with the lower assembly 33 have a smaller radius than the guide surfaces of the two other bearing assemblies, because they are closer to the axis of oscillation YY.
  • the device is supplemented by means for actuating and holding the movable frame relative to the fixed frame.
  • actuating means comprise two jacks 50 arranged on two opposite sides of these frames and which are connected to a control device, known per se, and which will not be described in detail here.
  • This control device comprises means for supplying the cylinders with hydraulic fluid and a control circuit comprising photocells or other sensors of the position of the strip which, as a function of the position of the latter, ensure the supply jacks so as to move the movable frame in a proper direction to return the strip to its centered position.
  • the angular movement between the two extreme positions of the guide roller can be, for example, of the order of 15 ° in a particular application.
  • this axis can be slightly offset without significantly modifying the operation of the device.
  • the angle which this axis forms with a reference direction which can be the direction of the adjacent strand of the strip to be guided can be chosen in a range between 5 and 30 ° , preferably between 7 and 20 ° , for the applications considered.
  • the invention therefore makes it possible to divide the elongation on the bank by 4.
  • this device is how in the embodiment shown in FIGS. 3 to 5, the roller is carried by a frame 1OLa mounted relative to an intermediate frame 10b in accordance with the teaching of the second prior device described at the head of this thesis, that is to say oscillating about an axis ZZ horizontal and orthogonal to the XX axis, and located at a certain distance below this XX axis.
  • This intermediate frame 10b is itself mounted on the fixed frame 1 in accordance with the invention.
  • Actuating cylinders 51 are provided to move the frame 10a relative to the frame 10-b, as well as locking devices 52, 53 to selectively secure the frame 10a to the frame 1 0E or else the frame 1 Ob to the frame 1.
  • the means for guiding the movable frame relative to the fixed frame may consist of thrust bearings with balls, needles, a crown or any other suitable means.
