Abstract

The invention relates to a device for stamping distinguishing marks on parts moving in the feed direction of a roll line, comprising at least one mark-holder for holding a mark, the mark-holder being placed on the circumference of a stamping wheel. The inventive device comprises an eccentric stamping wheel which is mounted so as to rotate in a stamping unit and which can be accelerated in rotation by means of driving mechanism in synchronism with the speed of the parts to be stamped with a distinguishing mark. The stamping wheel applies a force on the parts to be stamped with a distinguishing mark which can be adjusted continuously and constantly. It is possible to adjust the horizontal, vertical and possibly oblique orientation of the stamping position of the stamping wheel. The inventive device is also characterized in that it comprises a range measuring device for the moving parts, which is used to control a horizontal driving mechanism for tracking the stamping unit carrying the stamping wheel.

Claims5

Dependent claims

An apparatus for marking a surface of parts moving on a roller table in a travelling direction at a predetermined speed, which comprises

(a) a stamping unit displaceable against an infinitely adjustable force transversely to the surface of the parts to be marked,
(b) a drive for adjusting the stamping unit perpendicularly to the travelling direction and parallel to the surface of the parts to be marked,
(c) a measuring device controlling the adjusting drive in response to a measured transverse distance between the stamping unit and the parts to be marked,
(d) an eccentric stamping wheel carrying on its circumference a character carrier for at least one character and rotatable in the stamping unit about an axis of rotation extending perpendicularly to the travelling direction and parallel to the surface of the parts to be marked, the stamping wheel having a cylindrical surface eccentric to the axis of rotation, and
(e) a drive for rotating the stamping wheel at a high speed of acceleration and synchronously to the speed of the parts moving in the travelling direction about the axis of rotation.
