Definitions

  • This invention relates to a device, called a spinner head, for reshaping the Lip of ballpoint pen tips, with two freely rotatable in the spinner head Spin rolls that have shaped disks that define a gap between them in the a tongue that can be moved against a spring and has a V-shaped end face protrudes.
  • the hole in which the ball sits has pockets or grooves in the bottom area which transports the writing fluid, hereinafter referred to as "ink" becomes. Also it is not a real blind hole, because from its bottom a hole with one Diameter, smaller than that of the ball, leads to the ink supply.
  • the edge has been flanged for many years using the following method, which is described in US Pat. No. 3,135,231:
  • the flanging device called the spinner head
  • the spinner head has two shafts which run in the vertical direction and are arranged parallel to one another. At their lower ends, these bear essentially circular, hard shaped disks that taper conically downwards.
  • the entirety of the shaft and shaped disc is called a spin roller and is freely rotatable.
  • the peripheries of the shaped disks have a small gap-like distance. In the middle of this gap, a hard, thin tongue with a V-shaped end face is axially displaceable against a spring.
  • the spinner head can be rotated about the axis of symmetry of the two shafts of the shaped disks and is also driven to rotate about this axis.
  • the mode of operation is now as follows: It becomes a writing tip including a ball, coaxial to the The axis of rotation of the spinner head is guided into the gap between the shaped disks the ball first comes into contact with the V-shaped face of the tongue. Thereby the ball and the nib are securely centered and positioned in the Level of tongue. As a result, the tongue is moved against its spring and the The writing tip comes into contact with the freely rotatable shaped disks. This causes centering in the plane normal to the tongue plane. The axial Pressing the writing tip and the spinner head together takes place with predetermined Force and over a predetermined number of relative rotations. Through the Relative rotation between the writing tip and the spinner head are the shaped disks in Rotation offset.
  • This apparatus has essentially proven itself and more than half of all Ballpoint pens worldwide using this method and with such devices manufactured.
  • this device has a disadvantage that is within the narrow limits given geometrical proportions of the individual parts is justified.
  • the two parallel shafts of the shaped disks are also extreme Miniaturization and use of special radial flat bearings not possible, come under a distance of the two axes of rotation that is less than about 10 mm.
  • the diameters of the shaped disks are also approximately 10 mm each mandatory.
  • the writing tip usually has one in the area of its lip Diameter from about 0.6 to 1.2 mm and is accordingly heavily curved.
  • the Ratios of the curvatures of the writing tip: the shaped disk thus range from about 1:16 to 1: 8. These proportions cause a relatively large contact area and thus a low Hertzian surface pressure. With greater Hertzian surface pressure the kneading material is better "kneaded". The The most effective way to do this is to reduce the contact area, which can be achieved by Raising the curvature ratio to 1: 4, for example.
  • US 3,135,231 A also describes an embodiment in which the two shafts of the Shaped discs are not arranged parallel to the axis of rotation of the spinner head but at an angle so that they intersect their axes on the axis of rotation.
  • One reason for this Arrangement is not specified, in practice it will, probably because of the costly Manufacture of non-parallel seats for the shaft bearings, not used.
  • the invention solves this problem in that two shaped disks with aligned Axes are used, the end faces of each other leaving a gap face each other. In this way it is achieved that the diameter of the Shaped discs much smaller than can be kept in the prior art.
  • FIG. 1 is a schematic view of a spinner head according to the invention
  • 2 is a schematic top view of the device of FIGS. 1 and 3 shows a detail on an enlarged scale.
  • a spinner head essentially exists of two shaped disks provided with coaxially arranged shafts 2.
  • the shafts 2 are radial by means of ball cages, not shown held balls 3 out.
  • Each shaft 2 is axially supported by means of a Ball 5, which rests on its end surface facing away from the shaped disk 1.
  • the ball 5 that is also held in the ball cage, not shown, is supported against a support 6 of the spinner head.
  • the balls 5 and the total length of the spin rolls determine the Position of the gap and position of the spin profile of the shaped disks.
  • Each shaped disk 1 essentially has an end face and a spin profile, which in this application means the area of the surface that is the lip processed.
  • the small dimensions of the form rollers are included in the size comparison the writing tip also shown. You also achieve one Substantial reduction in the mass of those preferably made of tungsten carbide Spin rolls over those of the prior art. By the substantial reduction of the diameter to about 4 mm, the above-mentioned is achieved according to the invention target curvature ratio of 1: 4 and above.
  • the invention is not limited to the illustrated embodiment, but can be modified and designed in various ways.
  • Spinner Head is located above the writing tip, but this is not necessary the axis of rotation between spinner head and writing tip can also run horizontally or the writing tip, with vertical axis of rotation, from above into the ones below it Spinner Head can be moved.
  • the position of the support 6 can also be determined by means of a Adjusting mechanism (adjusting screw, washer, etc.) are changed, it needs do not have the circular shape shown in FIG. 2.
  • the movements in the example as Define up and down movement of the print head and rotary movement of the spinner head goods can be done differently. It has proven advantageous that the spinner head rotates about its main axis, but is not axially movable.
  • the nib is not rotating, is moved axially until the writing ball first with a flank and then with the other side of the spring-loaded, V-shaped tongue comes into contact.
  • the writing tip against the spinner head will result in the writing tip in Brought contact with both form washers and also in the direction normal to V-shaped tongue centered.
  • they will become free rotatably mounted shaped discs by the rotation of the spinner head in rotation offset and the lip is reshaped.
  • the writing tip sits in one Collet that is mounted with little radial play to ensure that despite geometric error, both of the nib and the device, the nib can be centered freely as described above.
  • the axial feed is cam-controlled, whereby it is limited by a fixed stop becomes. It is also possible to increase the maximum by an axially acting spring Limit feed force.
  • This spring must be the counterforce of the spinner head intended to overcome and significantly weaker spring of the V-shaped tongue first then ensures the force for reshaping the lip.
