Definitions
- This invention relates to a device designated as a rotary head for deforming the edge of the points of ball-point pens, comprising two rotary rollers installed so as to be able to rotate freely in the rotary head, which have forming discs which delimit a slot in them. which protrudes from a front V-shaped tongue which can be moved against a spring.
- the balls When mounting hard balls of ball-point pens in their seat of the writing point consisting of moldable material of the ball-point pen, the balls are first inserted in a substantially cylindrical blind hole and then the edge of the point of writing which protrudes above the equator of the ball, is clamped by plastic deformation so as to surround and hold the ball in the area "above” the equator.
- the hole in which the ball sits has pockets or grooves in the area of its bottom by which the writing liquid, hereinafter referred to as "ink” for simplicity, is transported. It is also not a real blind hole, because from its bottom a bore with a diameter smaller than that of the ball leads to the ink reserve.
- the clamping device called rotary head has two rods arranged parallel one with respect to the other oriented vertically. These support at their lower ends circular hard forming discs which tapering substantially in a cone downwards.
- the assembly of the rod and the forming disc is called a rotating roller and is installed so that it can pivot freely.
- the peripheries of the forming discs have a small slot-like gap. In this slot is arranged in the center a hard and thin tongue with an N-shaped front surface which can move axially against a spring.
- the rotary head can rotate around the axis of symmetry of the two shafts of the forming discs and is also rotated around this axis.
- the operating mode is then as follows: A writing tip with its ball is guided eoaxially with respect to the axis of rotation of the rotary head in the slot between the forming discs and the ball then first comes into contact with the N-shaped front surface. This ensures safe centering and positioning of the ball and the writing tip in the plane of the tongue.
- the tongue is then offset against its spring and the writing tip comes into contact with the forming discs installed so that it can pivot freely. This results in centering in the plane normally with respect to the plane of the tongue.
- the axial compression of the writing tip and of the rotary head 1 'against each other is done with a predefined force and thanks to a predefined number of relative rotations.
- This device nevertheless has a drawback which is due to the predefined geometric ratios of size within narrow limits of the different parts. Due to the two shafts oriented parallel to the forming discs, it is not possible, even with extreme miniaturization and using special bearings to be mounted flat in the radial direction, to obtain a gap between the two axes of rotation which is less than about 10 mm. The diameters of the forming discs are thus also fixed imperatively respectively at around 10 mm.
- the writing tip usually has a diameter of about 0.6 to 1.2 mm in the region of its edge and is therefore strongly curved.
- the ratios of the writing tip: forming disc curvatures thus range from approximately 1:16 to 1: 8. These size ratios result in a relatively large contact surface and thus a low Hertz surface pressure. With a higher Hertz surface pressure, a better "kneading" of the material of the writing tip is obtained. The most effective way to do this is to reduce the contact area, which can be done by increasing the curvature ratio up to 1:
- the object of the invention is to create a device in which the curvature ratios indicated above are achieved and in which the desired position of the forming discs can be respected.
- the invention achieves this objective by the fact that two forming discs are used with aligned axes, the front surfaces of which are located opposite one another, leaving a slot. In this way it is possible to keep the diameter of the forming discs substantially smaller than in the prior art.
- FIG. 1 a schematic view of a rotary head according to the invention
- FIG. 2 a schematic top view of the device of FIG. 1, and
- a rotary head essentially consists of two forming discs 1 provided with rods 2 arranged coaxially.
- the assembly of the forming disc and of the rod, which is most of the time made in one piece, is designated below as a rotary roller.
- the rods 2 are guided radially by means of balls 3 held in ball cages, not shown.
- the axial positioning of each rod 2 is achieved by means of a ball 5 which rests on its end surface diverted from the forming disc 1.
- the balls 5 and the total length of the rotary rollers define the position of the slot and the position of the rotary profile of the forming discs.
- Each forming disc 1 has substantially a front surface and a rotary profile, by which is meant in this application the area of the surface which shapes the edge.
- a substantial reduction with respect to the state of the art of the mass of rotary rollers preferably composed of tungsten carbide. Due to the substantial reduction in diameter to approximately 4 mm, the above-mentioned curvature ratio targeted by the invention is obtained of 1: 4 and more.
- the invention is not limited to the embodiment presented, but can also be modified and organized differently.
- the rotary head is always disposed above the writing tip, but this is not mandatory, the axis of rotation between the rotary head and the writing tip can also extend to the horizontal or the writing tip, in the case of a vertical axis of rotation, can be moved from the top into the rotating head located below it.
- the position of the support 6 can also be modified by means of an adjustment mechanism (adjusting screw, wedging plate, etc.), it does not need to have the circular shape illustrated in FIG. 2.
- the rotary head can rotate about its main axis but not to be movable in the axial direction.
- the writing tip does not rotate, moves axially until the writing ball comes into contact first with one side and then with the other side of the V-shaped tongue loaded by spring.
- the writing point is brought into contact with the two forming discs and is also centered in the direction normally with respect to the tongue in the form of V.
- the forming discs installed so as to be able to pivot freely are offset in rotation by the rotation of the rotary head during the continuation of the axial movement and the deformation of the edge takes place.
- the writing tip rests in a clamp which is installed with a small radial clearance, in order to thus guarantee, despite the geometric defects presented by both the writing tip and by the device, that the writing tip can be centered without obstacles as described above.
- the axial advance is made according to a controlled curve, while being limited by a fixed stop. It is also possible to limit the maximum advance force by means of an axially acting spring. This spring must first overcome the counter-force exerted by the clearly weaker springs of the N-shaped tongue provided in the rotary head and then guarantees the deformation force of the edge. It is essential that the forming discs are first offset in rotation by contact with the edge, with negligible slip, which is obtained thanks to the low mass achieved in the context of the invention for rotary rollers and their bearings. as well as the Hertz pressure force between the rotating rollers and the edge.
