Definitions

  • the invention relates to a method for flanging the edge of a jacket made of film material, in particular a paper cup rim, by means of a flanging ring moved axially against the jacket edge, and to a device for carrying out this method.
  • the flanging ring lies parallel to the plane of the edge to be flanged and generally in a radial plane to the axis of the casing forming the edge and to its direction of advance. It has a crimping groove corresponding to the shape of the edge, which is rounded in the radial section in order to force the material to be crimped onto the desired bend and curl during the feed movement. Considerable friction occurs between the flanged material and the flanging ring, which has to be absorbed as an axial force by the jacket forming the edge to be flanged.
  • the invention has for its object to provide a device of the type mentioned that the flanging without endangering the jacket also among those mentioned difficult conditions allowed.
  • the solution according to the invention is that the flanging ring is subjected to an additional movement with changing direction during the flanging. As a result, a constant additional relative movement between the flanging ring and the flanging edge occurs during the flanging, by means of which the friction is significantly reduced. This movement can also directly promote the flanging process.
  • a wobble movement is selected as an additional movement.
  • the maximum crimping force is reduced to that small circumferential section in which the crimping ring protrudes the most towards the edge to be crimped.
  • the neighboring areas of the jacket are relieved and support the area under load.
  • the wobbling movement of the flanging ring causes a constant additional relative movement of the flanging ring to the edge to be flanged, by means of which the frictional force to be absorbed by the jacket in the axial direction is reduced.
  • a wobble movement is understood by the invention to be primarily the movement that occurs when a plane rotates that is not perpendicular to its axis of rotation coinciding with the central axis of the crimp ring.
  • the term in the sense of the invention is also intended to include movements in which opposite points of the flaring part of the flanging ring perform different and rapidly changing movements in the axial direction.
  • a radial movement with an alternating radial direction can also be expedient. This is primarily to be understood as the type of movement which the crimp ring held against rotation performs, for example, under the action of a crank with a small crank radius. The movement takes place continuously in the direction of an orbiting radius. Instead, it can also be achieved by moving the flanging ring back and forth in two transverse radial directions, these movements being phase-shifted with respect to one another by a fixed or changing angular amount.
  • the wobble path i.e. the distance between the furthest forward and furthest back position of a point within the flaring part of the flanging ring in the event of a wobble movement is advantageously between 0.1 and 2 mm, preferably between 0.2 and 1.2 mm. It can be smaller the greater the wobble speed, which is expediently between 1 and 40, in particular 1 and 10 revolutions during the flanging process.
  • the distance of a radial movement is expediently smaller, namely between 0.05 and 1 mm, preferably between 0.1 and 0.5 mm, while the expedient speeds are the same as those just mentioned.
  • a device which axially supports the non-rotatable crimp ring is particularly advantageous rotatably drivable, inclined to the radial direction support surface is formed.
  • This support surface is expediently defined by the contact points of three rollers on the lower surface of the flange ring.
  • a particularly simple shape results if the roller axes of these rollers lie in the same radial plane and have different diameters.
  • a paper cup 1 with an edge 2 to be flanged is held in the position shown by a holder, not shown. Its central axis 3 coincides with the axis of a bore 5 provided in a machine part 4 which is fixed (at least during the flanging process) and in which the outer body 6 of the flanging device is held.
  • a spindle 8 is rotatably mounted coaxially to the bore 5 and the outer body 6 and can be driven in rotation by means of a V-belt drive 9/10. It carries a flange 11, of which three axes 12, each offset by 120 ° to one another, project radially in the same plane. On these axes run two rollers 13 of the same size and a roller 14 which is a little (approx.
  • the flanging ring has in the usual way an annular groove 21 with a rounded cross section, which is intended to cooperate with the edge 2 of the cup 1 for flanging.
  • the trough 21 is expediently located on the inside or near the plane of the spherical roller bearing 15 if no or only subordinate radial movement components are to occur during the wobble movement. If, however, a certain radial component is also desired, one chooses an axial offset, as shown in the drawing, or a weakly eccentric crank arrangement of the spindle extension 15.
  • the flanging ring 17 undergoes a wobbling and radial movement with a circumferential direction, through which all circumferential locations of the flanging channel 21 are successively advanced to the edge 2 of the paper cup 1 in order to deform it.
  • this wobble movement is superior to a feed movement of the flanging ring 17 relative to the cup 1 in a known manner.
