Definitions

  • the present invention relates to a crimping head according to the preamble of claim 1.
  • a device of this type intended for sealing the cans by crimping the lid onto the can body, is known from the US patent -A-2 907 293.
  • this document shows a crimping device for cans containing guide means formed by two superimposed cam rollers moving on two cam surfaces each having a straight vertical face.
  • This device does not allow easy adjustment of the clearance between the assembly of the two rollers and the cam and cam follower surfaces between which this assembly is interposed.
  • the object of the present invention is to remedy the drawbacks of the devices of the prior art.
  • Such an arrangement allows that the play can be eliminated by adjusting the position, in the axial direction, of the second roller relative to the cam follower surface.
  • the second roller has a diameter smaller than that of the first roller and the cam surface has a transverse dimension covering the combined thickness of the two juxtaposed rollers, while the cam follower surface has a transverse dimension lesser, such that it extends only opposite the second roller.
  • the cam and cam follower surfaces are formed by the sides of a groove hollowed out in a plate along an appropriate layout and with a constant cross section, the second roller being adjacent to the bottom of this groove.
  • the distance between the cam follower surface and the work surface is constant, and the clearance is adjusted by moving the second roller, at least, in the direction of its axis relative to said plane.
  • the mutual difference of the two rollers in the direction of their common axis is constant. This means in particular that, when the adjustment is made by axial displacement of the second roller, it is in fact the two rollers which are moved together. Such an arrangement has no effect on the precision of the guidance, since the cam surface is a cylindrical surface of generatrices parallel to said axis.
  • the two rollers are mounted coaxially around the same journal on which they are fixed in the axial direction, and this journal is subject to the support part of the wheel by fixing means allowing the adjustment of its position relative to said plane in the direction of the common axis of the two rollers.
  • the pin may have a threaded end which is screwed into a threaded cavity formed in said support piece in the direction of the common axis of the two rollers, this cavity being opened by a radial slot so that it is located produced between two elastically deformable fork legs, which can be mutually tightened or loosened to block the trunnion between them on the support piece or allow its position to be adjusted by progressive screwing or unscrewing.
  • Figure 1 illustrates the kinematics of a crimping head for shaped boxes.
  • Figure 2 shows schematically, in axial section, the main elements associated with a wheel in a crimping head according to the invention.
  • Each wheel 3 is carried by a part 4 comprising a hub 4a pivoting about a vertical axis Y, and two arms 4b, 4c secured to the hub 4a.
  • the wheel is mounted at the end of one of these arms, designated by the reference 4b, to which its axis of rotation V is linked.
  • the pivot axis Y of the hub 4a is required to rotate around the axis X from the crimping head, remaining at a constant distance R from this axis.
  • a roller 10 At the end of the other arm 4c of the support piece 4 is mounted a roller 10 whose axis of rotation Z, vertical, is linked to this arm.
  • the roller 10 is forced to roll against a cam surface 7a whose layout is such that it imposes on the wheel 3, via the part 4 while the hub 4a of the latter performs its movement of revolution around the axis X, strictly follow the outline of box 1 to be crimped.
  • This result is illustrated in FIG. 1, where two positions D, D 'of the part 4 and its accessories have been indicated, which, in the position D', are designated by the same references as in the position D, but assorted of the sign ['].
  • FIG. 1 shows that the hub 4a is mounted between the branches 5a, 5b of a part 5 further comprising a rotary sleeve 5c centered on the axis X, which can rotate around this axis but not move along that -this.
  • the hub 4a can rotate around the axis X, its own axis Y remaining at a constant distance R from the latter, while maintaining a constant spacing with the plane P, that is to say by describing a circle of axis X parallel to the plane P and distant from it by a fixed fixed quantity.
  • the wheel 3 is forced to move while remaining at a constant height above the plane P.
  • the head 4d of the arm 4c located at the end of the latter remote from the hub 4a, which moves while remaining in a mean plane Q parallel to the plane P and located at a fixed fixed distance H from this plane.
  • the head 4d of the arm 4c is equipped with a guide assembly 6 including the aforementioned roller 10, which compels the latter to follow, when the hub 4a rotates around the axis X, the cam surface 7a, produced in a fixed plate 8 known as a "reproduction cam", located at a determined distance J above the plane Q.
  • This surface is a cylindrical surface whose vertical generators rest on a line such that the axis Z of the roller 10 follows a line G designed so that the axis V of wheel 3 moves accordingly along a path T "reproducing", taking into account the radius of the wheel, the outline of box 1.
  • the guide assembly 6 comprises a pin 9 fixed to the head 4d and offering a general shape of revolution around a vertical axis Z; this journal carries, in addition to the roller 10, a second rotating roller 11; these two rollers are mounted one above the other so that they can rotate around the same axis coinciding with the aforementioned axis Z.
  • the lower roller 10, of slightly larger diameter than the upper roller 11, has a cylindrical outer surface of revolution of axis Z and rolls against the cam surface 7a.
  • the upper roller 11 for its part has an outer surface of revolution not cylindrical, but curved, its section through a radial plane, passing through the axis Z, being constituted by a slightly convex arc towards the outside.
  • This roller cooperates with a cam follower surface 7b, produced in the plate 8 facing the cam surface 7a.
  • the surface 7b extends, like the surface 7a, following a path parallel to the line G along which the Z axis must move. It is also a regulated surface, including the generators, instead of being parallel to the Z and X axes , make with them a small angle F of a few degrees.
  • the distance between the cam 7a and cam follower 7b surfaces which form the sides of a groove 7 hollowed out in the plate 8, decreases as one moves away from the head 4d of the piece 4. As for the roller 11, it is adjacent to the bottom 7c of this groove.
  • the cam follower surface 7b does not continue, in the direction of the head 4d, beyond the roller 11, so as not to interfere with the roller 10, of larger diameter, interposed between it ci and said head.
  • the pin 9 is fixed to the head 4d by a threaded part 9a of axis Z which it comprises, which is screwed into a threaded conjugate passage which comprises the head 4d.
  • a threaded part 9a of axis Z which it comprises, which is screwed into a threaded conjugate passage which comprises the head 4d.
  • the convex roller 11 slides along a generatrix of the cam follower surface 7b inclined by the angle F relative to the axis X; it follows that, when one increases, by adjusting the position of the part 9 on the axis Z, the distance K of the roller 11 to the fixed plane Q where the head 4d moves, the clearance which existed between the surfaces 7a, 7b and the rollers 10, 11 of the guide assembly 6 decreases until it cancels, the two rollers 10, 11 then simultaneously pressing each against the surface 7a, 7b with which it cooperates, the roller 10 being in linear contact with the surface 7a and the roller 11 in point contact with the surface 7b.
  • the pin 9 When this setting is reached, the pin 9 is blocked in the head 4d by clamping its threaded part in the threaded passage of the head 4d, the latter being for this purpose open by a slot 13; a screw is engaged in holes 12 drilled in the two corresponding branches, separated by this slot, for tighten elastically these against the threaded part 9a of the pin 9 and lock the latter by pinching.
