Definitions

  • the invention relates to a method for controlling writing instruments, in particular ball pens, on paper, in which the writing instrument is guided in a repetitive motion with respect to the plane of the paper and the paper is moved in a sense ahead.
  • the control devices for writing instruments, in particular ball-pens have the following structure:
  • the device has a socket installed so as to be able to pivot for a clamp of tightening that holds the ballpoint pen.
  • the collet is installed in the socket with a limited axial clearance and a small radial clearance, most of the time 0.2 mm, relative torsion is avoided thanks to a trainer.
  • the writing instrument is held at a predefined angle with respect to the paper and possibly rotated about its longitudinal axis.
  • the writing pressure is preferably defined by a weight.
  • the socket for the writing instrument (most of the time, several of these, preferably ten, are arranged next to each other) is installed in the recording apparatus so that it performs circular movements with respect to the plane of the paper (10 to 90 rotations / minute are described in a circumference of 100 mm for example, which corresponds to writing speeds of 1 m / min. at 9 m / min.).
  • the paper on which one writes for control purposes is most of the time unwound from a roll and moved at a speed that can be chosen under the socket, which is referred to as an advance movement.
  • PSU 10 Write Testing Machine The device marketed by the MINITEK Company under the designation "PSU 10 Write Testing Machine” (PSU 10 writing test machine) performs the above process, it has been used since 1962 at the main manufacturers and is the technical basis of standards. These and other devices using the same process worldwide control the quality of production of about 100 million ball pens per day!
  • the object of the invention is to develop a test method for the control of ball pens which avoids the disadvantages of the known method with regard to tips, angles, different accelerations and write overlays.
  • the test is performed so that the ball pen (or several ball pens) is moved back and forth on a carriage transversely to the paper advance movement between two predefined end points. It then presents, in the zone of extreme points, a minimum speed or remains at rest for a predetermined time at the extreme point. The paper advance movement takes place during this time. The movements are then coordinated so that the resulting line forms a meander which consists of rectilinear trajectories.
  • the writing instrument can be rotated continuously about its longitudinal axis, while retaining a predetermined relationship between the number of rotations and the number of movements back and forth, for example a rotation all the 50 movements back and forth.
  • the writing instrument is kept in an oblique position (60-70 °) predefined and constant with respect to the paper, the lines described by the movement of the carriage transversely with respect to the direction of advance of the paper represent applications or smears, while the movement in the direction of advance of the paper is equivalent to a sort of transversal plot. Due to the controllable controlled acceleration also achieved by modern technique when leaving the end points, a dynamic way of writing in a repeatable manner is taken as the basis of the test and defects and problems of the writing instrument in a relatively simple manner due to the thinner and thicker sections of lines "strolling" through the pattern.
  • the pattern obtained then shows structures that allow to conclude geometric irregularities of the writing tip, the ball, etc.
  • test patterns (originals) according to the state of the art give significant interference phenomena. These appear because the defects are classified, because of the neighboring areas, in types that the human eye, but also semiautomatic or fully automatic optical recognition devices, can perceive very precisely and that can be associated by the skilled person to different defects of the writing instruments.
  • the figure 2 shows a test pattern according to the method of the invention which takes into account these characteristics and gives test patterns such as that shown.
  • the test pattern shows a so-called meandering line, which means in the context of the invention that the substantially straight-line sections which extend substantially under each other at a right angle are grouped together to form an angular line which winds.
  • the advance movement of the paper is preferably provided by a stepping motor which is activated or deactivated for example by the position of the carriage.
  • the figure 3 schematically shows a ball pen 6 ready to write but not yet placed on the paper, the ball 1 of the inner contour of the tip 2 of the ball pen 6 is raised on all sides and is surrounded by ink of ballpoint pen and centered. The ballpoint pen ink itself is not shown for visibility reasons.
  • the plane passing through the central point of the ball 1 normally relative to the axis 5 is called the equatorial plane. Between this plane and the outlet port of the mount is the curved gap called "gap 7" for the writing fluid.
  • gap 7 is about 1.5 to 4 micrometers (diameter difference 3 to 8 microns).
  • ink channel 3 which opens into an annular shaped intermediate accumulator 8.
  • Five or six ink channels are usually provided in the tip, distributed evenly around the periphery.
  • ⁇ alpha
  • this is the angle between the axis 5 of the ballpoint pen 6 and the writing surface, in the illustrated case a sheet or a piece of paper 4.
  • the figure 4 shows the changes that occur as soon as the writing instrument is placed on the paper 4:
  • the ball 1 is pushed in its seat upwards and inwards so that the intervals 7 available for routing and the evacuation of the ink from the ballpoint pen becomes of uneven thickness.
  • the application movement only the thinned upper zone of the interval remains available for the conveyance of the ink, while the lower zone wide of the interval is available for the removal of excess ink.
  • the movement of the ballpoint pen normally in relation to the plane of representation of the figure 4 , said transverse plot, has, compared to the application or the smear, a gap 7 configured in a not so different manner and is not shown, but it also contributes, depending on its length, to the possible ink deposit in the form of a dot on the paper mentioned above.
  • the angle ⁇ (alpha) between the surface of the paper 4 and the axis 5 of the writing instrument 6 obviously also has an influence on the writing quality and is maintained during tests according to the state of the art. at 60 ° or 70 °. Other dimensions or even variations during the test are obviously conceivable, but this only concerns variants or sub-concepts of the invention.
  • This type of variant also includes the setting of the number of back and forth movements, the fixing of the different speeds or changes in speeds and the ratio respectively chosen between the speed of advance of the paper and the speed of the transverse movement. It is also necessary to define the regulation of the ratio between these speeds and the rotational movement of the writing instrument 6 about its axis 5 because of the possibility of repetition of the results, but this only concerns parameters for realizing the invention without affecting the essence of the invention.
  • a plug 11 is a member of a carriage not shown, it supports inside a sleeve 12 installed so as to pivot.
  • This sleeve supports, if necessary in one piece, a toothed wheel 13 and has a longitudinal slot in which exceeds in the interior of the sleeve 12 a driver 16 of a collet 14.
  • the collet has, as mentioned in introduction, a small radial clearance and is axially movable within limits.
  • At the upper end of the collet is an interchangeable weight 15 which blocks the writing pressure to a precisely defined level.
  • the collet 14 holds a test sample 15. This has at least one ball point and a reserve of ink.
  • the figure 5 shows purely schematically the evolution of a test line with indication of the direction of advance V for the paper 4 and the movement of the carriage UD for application or smear.
  • an elevator 17 with which the test sample 15 can be lifted off the paper.
  • An elevator 17 can obviously be provided in common for several test samples.
  • the method of the invention can also be used for paper pencils, colored pencils, chalks, fountain pens and other writing instruments. Especially for paper pencils or graphite mines, it is important that there are no writing overlays in order to make practicable measurements by means of a densitometer in practice.
