Bauffiannstrasse 16 Designation: Axis for locking and

Setting of on her "any, esp gradually rotatable wheels

The invention relates to an axle with a locking bracket for setting and fixing wheels mounted on it so that it can be rotated step by step as desired, primarily for printing type wheels of stamping, printing or labeling machines, with a number of wheels next to each other on λ

the axle arranged sit, and a wheel each in its division on the axis by corresponding Rotation can be changed, while the other wheels here against rotation in their setting position are secured.

In such a guided and on an axis in their setting positions to each other optionally changeable wheels, special care must be taken to ensure that the wheels are in every setting each other, across their circumference in the transverse direction seen in a line or plane exactly aligned, i.e. not e, twa in the radial direction different settings lying down

In the wheel circumference xu β inender can arise. In Use on stamping, printing or labeling machines, for example, would be in this lall an uneven print image of printer types requesting on the wheel circumference on the one, Wheels sitting next to each other on the axle are created. The one-of-a-kind printing types would therefore be disadvantageous la overall print image next to each other old different strong imprints appear »during a Good print image requires the same reproduction strength for every single printer type.

For printing machines with several side by side on one axis, and independent of each other optionally adjustable type wheels, it is known (US Pat. No. 1, 868,997) »in a recess in the longitudinal direction of the axis for each type wheel associated coupling parts under intermediate bearings to store a compression spring opposite the bottom of the trough-like recess in the axis, so that a kind of friction clutch under the action of these compression springs vt) n the embedded dome parts opposite each character wheel within its hub bore towards the axis are there by means of a zuaät »borrowed, only slidable rod engaging a longitudinally projecting rib in recesses in each case «wipe two equally spaced on the circumference of the wheel Only one type of printing wheel is excluded from this, which one is in his attitude to the locking rib of this additional Schlebeetsnge just an interruption or recess in this rib is opposite, so that the corresponding preceding paragraph of the printing type scope is bridged like a fork, and then this individual type wheel by changing the separate axis of rotation with embedded feeib coupling part under spring pressure effect accordingly

“It can be rotated to choose another one To set the print type

For such printing machines it is also possible to choose » wise variable type adjustment known (üS-Patent-1, 131,959) »an adjustment axis su rerwenden, the is mounted both rotatable and longitudinally displaceable, and on the one hand «it on its« circumference Securing rib lying in the longitudinal axis direction sur The type wheels are locked to prevent them from twisting is, while additionally on this securing rib on the opposite longitudinal side of the axis, rounded arched · recesses of the number used Printing type wheels are provided according to one another, in which spring pressure is written Ball »i« is stored in the frame part of the printing machine and locks into place depending on the position of the axis and the separately ordered type wheel by means of the adjusting pin sitting on the axis under a single handle in Recesses radially inside the bath hub, at then following rotation of the axis «it rotated, optionally another printer type can be set. In both of the previously known versions, it is Eupplungs- or stored under federuck standing Grid parts have the common disadvantage that these loosely stored, standing under iederkraftffekt Parts “difficult to assemble” or when dismantling the machine xu for repair or other purposes and can easily be lost. But it is also known to «avoid these laughing parts, under compression spring force, the locking of Balls used for pressure tjpenwheels, or correspondingly to insert rounded bolt parts into radial blind holes located within the axis, which holes are slightly precharged so that the stored locking devices, especially those used for setting Parts are then fixed, but still out of scope

109834/0157

the axis still protrude so far under the action of the compression springs used that the lock the character wheels engaging this protruding rounded bolt parts or balls, which also result in disadvantages in the assembly, as it is hardly possible to make the blind holes caulk each evenly on the outside, so that accordingly the protruding locking parts too will protrude for different lengths · Correspondingly, the internal spring pressure from the axis will increase also have different forces on the type wheels within their hub bores what inevitably / an imprint in not straight Line with type indications slightly offset from one another, as well as with different imprint thicknesses the types lying next to each other will lead.

Finally, it is known (SP-I, 276,0 ^ 8) to achieve a uniform print image for tfLederdrüokhandatempel that Usual impression plate at the bottom with recess for the access of the printer types for the impression opposite the wheel drum elastiach designed to be displaceable when the stamping device is depressed. that the printing types always protrude sufficiently in the recess of the impression plate, and full on the stamp surface press on, so that at the same time a disgraceful leg or one-sided imprint no longer should be possible.

It is now the object of the invention, taking advantage of the locking by means of innerhsl embedded in the wheel axle, under the action of spring force standing balls or correspondingly outwardly rounded engaging bolt parts in Aueeparungen the hub bores of BBBK optionally on adjustable wheels, one on all baths evenly acting adjustment and locking

The subject of the application is characterized in that the locking axis is designed as a partially hollow housing part with a recess iaam that is continuously open to the outside in the longitudinal axis direction, for inserting ropes used to lock the wheels in the bottom of the recess worked into the bottom of the recess perpendicular to the center line of the axis, on the opposite side outwardly continuous £ && £ ϊ & ρ & with a shoulder of smaller diameter provided towards its end, so that only the ends of the also offset to smaller diameter, inserted into the bores, are bolt-like.
