Definitions

  • the present invention relates to a device for holding, positioning and driving a tubular support around which must be wound a continuous material, in sheet form, delivered at constant speed or not, according to the preamble of claim 1.
  • a device for holding, positioning and driving a tubular support around which must be wound a continuous material, in sheet form, delivered at constant speed or not, according to the preamble of claim 1.
  • Such a device is known from document FR-A-2 443 406.
  • the correct winding of the tissues around a tubular support, support which will be designated in the following description by the expression "tube” is generally carried out either by driving the support tube by tangential contact with at least one driving cylinder or , more generally, by placing the tube on which the material is to be wound on a mandrel actuated directly in rotation (axial drive of said support), this mandrel being generally of square section and being held, at each of its ends, by jaws clamp communicating the rotational movement.
  • the drive speed of the support mandrel is modified as the diameter of the winding increases, so as to have a constant linear speed and an equally constant tension.
  • the device for holding, positioning and driving a tubular support is characterized in that the mounting of the shell inside the housing is achieved by by means of a link also mounted pivoting about a fixed axis, integral with said lower cradle, the tightening and self-locking means associated with said shell being constituted by a link, the ends of which are mounted by means of axes respectively to the housing and the link, the self-locking being ensured by means of rollers mounted eccentrically on the shell.
  • the jaw according to the invention designated by the general reference (1), and which is capable of being used on any material making it possible to wind a sheet material on a tubular sopport , consists essentially of two elementary parts (2-3) articulated with respect to each other. These two elementary parts (2-3) define between them a cage (4) intended to receive the end of the support tube (5) around which the material is to be wound.
  • the part (2) of the jaw will be designated by the expression “lower cradle” while the articulated part (3) will be designated by the expression "clamping shell”.
  • the lower cradle (2) is mounted at the end of the driving axis (6), shown only in FIG. 4, to ensure the rotation of the jaw.
  • This axis (6) is supported by a bearing (7), a particular embodiment of which will be seen in more detail in the following description, and is rotated by any suitable means, for example by a motor (not shown ).
  • the shell (3) is pivotally mounted on the lower cradle (2) and comprises means ensuring the tightening and the self-locking of the end of the support tube during winding.
  • the retention and articulation of the shell (3) relative to the lower cradle (2) is obtained by means of a housing (8) mounted on the cradle (2) via 'a pivot axis (9).
  • This case has an open face (10) and a window (11) on its rear face, allowing it to pivot relative to the fixed lower cradle (2).
  • the mounting of the upper shell (3) inside this box (8) is carried out by means of a connecting rod (12) also pivotally mounted around a fixed axis (13) also integral with the lower cradle.
  • the cage (4) intended to receive the ends of the tube (5) consists of two circular sectors (or other shape) complementary (14) and (15), one (14 ) formed on the cradle (2), the other (15) on the shell (3).
  • the internal faces of these spans (14) and (15) are coated with a layer of protective felt material for example.
  • the shell (3) comprises means ensuring the tightening and self-locking of the support tube during the winding of the material.
  • clamping and self-locking means are constituted, in this embodiment, by the rod (16) whose ends are mounted, by means of pins (17-18), respectively to the housing (8) and to the link (12).
  • the self-locking is ensured by means of rollers (19-20) mounted eccentrically on the shell (3) which, in the closed position, come to bear on the periphery of the support tube (5).
  • a clamping force adjustment system constituted for example by a threaded rod (21) mounted on the shell (3), rod which cooperates with a nut (22) integral with the link (12), can be envisaged in order to better define the respective positions between the cradle (2) and said shell (3).
  • the jaw according to the invention is mounted on the drive shaft (6) by means of a bearing (7) of particular shape which, automatically , allows to position said jaw so that the lower cradle (2) is necessarily in the low position when it is desired to set up (or remove) the support tube.
  • the bearing (7) has an inclined front face whose base (23) serves as a fulcrum for the cradle (2), as well as the housing (8) when it is in the closed position.
  • the cutaway (24) of this bearing makes it possible to define the position of the housing (8) in the open position and consequently, to limit the pivoting of the shell (3) to the desired value allowing the positioning and removal of the tube (5).
  • the opening and closing can only be carried out with the cradle (2) in the low position.
  • Such a bearing shape also makes it possible to ensure very high operating safety of the assembly, taking into account that if, by mistake, the assembly is caused to rotate while the jaw is open, the cutaway will have tendency to automatically cause the shell to close.
  • FIGS. 5, 6 and 7 illustrate a variant in accordance with the invention making it possible to use a single device for tubes of variable section, for example of circular, hexagonal, square shape (references 5a, 5b, 5c to Figure 5) and this, at the cost of a simple and quick adaptation to achieve.
  • the handling of the assembly is facilitated by providing a peripheral flywheel (31) at the rear of the housing (8).
  • the immobilization of the tube and especially in the case of cardboard tubes can be improved by providing on the internal surface of the lower cradle (2) small pins which penetrate inside said tube without however the deteriorate.
  • the facing faces (32-33) of the cradle (2) and of the shell (3) may not be smooth and have complementary raised surfaces which interpenetrate (see FIG. 6) and avoid any relative displacement of two elements with respect to each other.
