Definitions

  • the invention relates to a method for actuating a lead advance of a pin and a device for carrying out the method.
  • feed mechanisms push button mechanisms are known in which a pin lead is led out by pressing one or more times a arranged on the rear pin end push button from the front end of the pin.
  • Such mechanisms are e.g. used in pencils, especially so-called case pencils.
  • rotary mechanisms are in use in which, as a result of interlocking threaded elements, a mine is unscrewed from the front end of a pin housing.
  • a cap On the front end of the pin housing. A cap not only protects the lead tip against damage or damage
  • Destruction of the entire mine can be enough.
  • the invention has for its object either to counter such damage by placing a cap or a schooner on a pin with too far untwisted mine or vice versa to avoid that a mine screwed into a patch cap without sharpener or shaper for the lead tip and is damaged.
  • Cap position is controlled, on the one hand can be used to prevent a lead out, in particular a turning out of the mine from the pin housing with the cap removed.
  • a significant lead feed is in a first embodiment of the invention by the coupling only possible when the cap is placed. Only when the cap is fitted, it is possible to push the lead tip further into the area of the cap, e.g. with a arranged there form or pointed element into engagement. In other words, the feed or rotating mechanism of the pin is actuated with the cap attached, and at the same time performing a molding or sharpening operation in the closed cap. This means with advantage that the pointed or mold waste of the mine remain in a designated cap interior and the environment is not polluted.
  • the coupling between the cap and the control element can be arranged or formed.
  • Feed mechanisms are within the scope of the invention.
  • the coupling is opened and closed in the pin longitudinal direction. This means that a coupling with two parts separates and closes in the pin longitudinal direction, so that an axial delay movement of a schooner or a cap on the pen tip can be particularly easily implemented in a coupling movement in the manner of a two-disc clutch.
  • an axially displaceable element in the pin housing can advantageously be biased by a spring, ie the coupling is due to the spring preload in
  • Feed element in particular a rotary actuating element on a rotating mechanism, which causes the unscrewing of the mine.
  • the coupling is advantageously effective between the feed element designed as a rotary actuating element and a driving element which is to be designated against the spring force of the coupling, which is here also to be regarded as opening spring coupling, for closing the coupling in the longitudinal direction of the coupling
  • Pen housing is moved.
  • An entrainment advantageously transfers the

  • a push-button mechanism is provided which is not coupled to the closing of the cap to be closed by the clutch, but the clutch-free limited feed of the mine, for. made possible by a few millimeters.
  • the feed amount which is made possible with the cap removed, is limited to approximately the length of an integrally formed or to be formed mine end of the mine.
  • a peaking or shaping of the free end of the lead is carried out by a disposed in the cap
  • the control is no longer displaced in the pin longitudinal direction in the pin housing, but is formed only as a rotatable element, the out and inward rotation of the mine is forcibly controlled by the rotation of the control.
  • the rotation of the control can be caused by the fact that on the Control at the front end of the pin, a first coupling part is arranged and at a positionable on the front end of the pencil cap or arranged therein a pointed or shaped element, a second coupling element. If the cap is properly placed on the pin end, the cap can be rotated relative to the pin housing, which as a result of said positive control of the control, the mine is moved out of the pin housing or driven into this.
  • a slip clutch can be realized by the engagement of the coupling elements.

  • the lead feed by rotation of the lead relative to the lead sharpener can be flexibly adjusted to a given chip or peel thickness of the lead sharpener independently of a completely exact setting of respective thread pitches. If the leadfeed is greater than the chip removal or peel volume of the leadcutter at the given feedrate, the lead will continue to be rotated about its lead axis, but the leadfeed will stop.
  • a handling part which is arranged or formed at the end of the guide sleeve facing away from the cap end of a guide sleeve insertable into the pin housing or the control element can also be rotated.
  • the rotation of such a handling part typically requires an advancing movement of the refill when the cap is attached and thus the clutch is closed.

  • Thread pitches - can be flexibly adjusted to a given chip or peel thickness of the mill pointper. If the lead feed is greater than the chip or peel volume at the given feed, the lead continues to be rotated about its lead axis, but the lead feed stops.
