Definitions

  • the invention relates to a printing unit, in particular for price labeling devices, in which the printing types can be set by means of adjusting wheels rotatably mounted next to one another about an axis, which have internal teeth into which a driver can be brought into engagement, which is axially adjustable at the free end and around its longitudinal axis rotatably fastened in a plain bearing-guided adjusting shaft and in which the adjusting shaft cooperates with a locking device which, according to the number of adjusting wheels side by side at intervals corresponding to the widths of the adjusting wheels, has locking recesses arranged parallel to the adjusting shaft as well as a resilient detent and in which the adjusting shaft is provided with a central longitudinal recess into which a pin engages, which is held on the housing wall opposite the slide bearing.
  • Such printing units are known from DE-PSs 19 29 307 (US Pat. No. 3,744,411) and 24 39 523 and from DE-OSes 22 47 732 (US-PS 3 968 745) and 27 15 462 .
  • the print types can be set in the print line.
  • the setting wheels are provided on their circumference with printing types and possibly also reading types, so that the setting wheels also form printing type wheels at the same time.
  • the locking recesses are arranged on the adjusting shaft.
  • the setting shaft is provided with the number of setting wheels corresponding to tangential circumferential grooves, which have spacings corresponding to the widths of the setting wheels and into which a resilient catch engages, which is arranged in the housing of the printing unit and is formed by a ball which is formed in a Bore of the housing is guided and which is under the action of a small coil spring.
  • the known locking device has the disadvantage that its production is complex and that its assembly is complicated and time-consuming.
  • this printing unit has the disadvantage that, in the case of printing units of the same width but with a different arrangement of wider or narrower printing type bands or printing type wheels, the arrangement of the wider ones adjusting shafts or narrower belts or wheels are required.
  • the printing type wheels provided with printing types have recesses on their circumference into which projections or teeth of the setting wheels engage.
  • a pointer that extends over the circumference of the adjusting wheels is axially immovably fastened on the adjusting shaft, which has a detent projecting at right angles to the adjusting shaft at its free end, which engages in the detent recesses of an easily replaceable detent rail.
  • a disadvantage of this printing unit is that the catch and the locking recesses cooperating therewith are at a distance from the setting shaft, so that bending moments have to be transmitted from the pointer. For this reason, the pointer must be designed and guided to withstand heavy loads.
  • the locking recesses are formed by bevels which are attached to the hubs of the setting wheels.
  • the bevels on the side of two adjuster wheels arranged side by side form a circumferential groove into which resilient catches arranged on the adjuster shaft engage.
  • This printing unit has the advantage that the setting wheels themselves form tangentially circumferential grooves, the axial spacings of which correspond to the respective widths of the setting wheels and the printing type bands guided above them.
  • this printing unit has the disadvantage that the grooves formed by bevels in the edge are only relatively cross-sectional can be small and these grooves are interrupted by the internal toothing of the setting wheels, which cooperates with the driver of the setting shaft.
  • the object of the invention is to provide a printing unit of the type specified in the preamble of claim 1, the latching device for the axially displaceable adjusting shaft can be easily adapted to the respective widths of the printing type wheels or printing type bands, in which the disadvantages of the known printing units described are avoided and at which the locking device is robust and highly reliable.
  • the pin is attached to the housing wall in an easily replaceable manner and the catch is formed by an inwardly resilient tongue of the adjusting shaft.
  • the latching device can be adapted to the respective arrangement of printing tape bands or printing wheel types of different widths will. No additional parts are required for the locking device.
  • the locking recesses have a wave-like or sinusoidal profile in the axial direction. If the pin is rigidly attached, the locking recesses must be formed as tangential circumferential grooves.
  • the cross section of the longitudinal recess and the cross section of the pin are out of round and that the pin is held on the housing wall so as to be rotatable about its longitudinal axis and are provided with at least two different rows of latching recesses.
  • the printing unit can be equipped in two, three or four ways with differently wide printing type bands or wheels.
  • the possible printing unit variants can be doubled if the rows of locking recesses are arranged asymmetrically with respect to the front-side contact surfaces of the pin and the pin can optionally be fixed to the housing wall with one or the other end.
  • the printing unit according to FIGS. 1 and 2 has five type bands 1, which have printing types 2 on their outer sides and which have driver knobs 3 on their inner sides.
  • the driver knobs 3 engage in tooth gaps 4, which are attached to the circumference of setting wheels 5.
  • the setting wheels 5 are rotatably mounted in a trough 8 between the housing walls 6 and 7.
  • the printing types 2 can be set with the aid of an adjusting shaft 9, which has an adjusting knob 10 at its outer end and which has a driver 11 designed as a pinion at its inner free end, which can be brought into engagement with an internal toothing 12 of the adjusting wheels 5
  • the setting shaft 9 is rotatable and axially displaceable in a slide bearing 13 arranged on the housing wall 6.
  • the setting shaft 9 has a central longitudinal recess 14 into which a pin 15 engages, which is held on the housing wall 7 by an insertion catch 16.
  • the pin 15 is provided with latching recesses 17 which are provided on the pin 15 at intervals which correspond to the distances between the setting wheels 5 from one another.
  • a resilient catch 18 is attached, which is formed by a tongue 19.
  • the tongue 19 is connected in one piece to the plastic setting shaft 9 and is formed by axially extending incisions 20. (See FIG. 3)
  • a pointer 21 and then the adjusting button 10 are pushed on.
  • the adjusting shaft 9 can be rotated relative to the pointer 21, while the adjusting knob 10 is connected to the adjusting shaft 9 in a rotationally fixed manner via the non-circular end region 22.
  • Carriers 11 and detent 18 can be arranged in the same plane running at right angles to the axis of rotation of the adjusting shaft 9 or can also be offset somewhat axially.
  • the cross section of the longitudinal recess 14 has two flattened sides 23.
  • the tongue 19 with the resilient catch 18 is arranged on one of these flattened sides.
  • the cross section of the pin 15 corresponds to the cross section of the longitudinal recess 14.
  • the pin 15 can therefore not rotate in the longitudinal recess 14.
  • the latching recesses 17, 17 'are arranged asymmetrically or axially offset from the end contact surfaces 24, 24' of the pin 15.
