Definitions

• the invention relates to a numbering with the features of the preamble of claim 1.
• Numbering machines of this type are used when continuous or randomly determined serial numbers are to be applied to a printed object, in particular a document, for example when printing check forms, bills or identity papers.
• a typical example of such a numbering machine is the Leibinger PC LEN device, which is used, for example, in printing presses of the Heidelberg GTOZ-NN-52 type for the printing of checks. Information about these devices is e.g. the brochure "High Security Numbering" of Leibinger.
• Said numbering machine has a housing with a removable for maintenance, cleaning or exchange with another character set in the housing wheel axle, on which a plurality of digit wheels are rotatably arranged.
• digit wheel in the context of this patent does not represent any limitation to numbers, but the term is used synonymously with the term “type wheel”.
• the easy removability of the wheel axle is important in order to carry out the necessary after the printing process cleaning and maintenance can.
• the number wheels are each individually adjustable and at least one digit wheel can be driven via a gear assigned to the digit wheel.
• the numbering unit has a drive shaft for each digit wheel connected to a drive unit
• a plurality of numbering units are often arranged on a shaft of a printing press, so that a fast and continuous printing process becomes possible.
• the more voluminous the individual numbering machines the greater the minimum distance between serial numbers which can be printed with two numbering machines arranged next to one another on a shaft.
• the more digit wheels are arranged on the wheel axle the more the problem is exacerbated, as more and more drive axles - and in the case of numbering engines driven by motors, more and more motors - have to be arranged in a given space.
• the object of the invention is to provide a compact numbering system which allows easy cleaning and maintenance of the wheel axle with a set of digits, which also makes it possible to quickly set the character combination to be printed. This object is achieved by a numbering with the features of claim 1.
• Advantageous embodiments of the invention are the subject of the dependent claims.
• the numbering mechanism according to the invention has a housing with a wheel axle arranged removably in the housing, on which a plurality of number wheels are rotatably arranged. Due to the removability of the wheel axle with number wheels is the easy cleaning and maintenance of these mechanical components guaranteed.
• the number wheels are each individually driven via a gear assigned to the digit wheel, wherein the numbering for each connected to a drive unit digit wheel has a drive shaft with a drive shaft connected to the drive pinion, so that a rapid adjustment of the character combination to be printed is made possible.
• An assignment of the digit wheel to the gear is in particular when the digit wheel and gear can not be rotated independently, so that each rotation of the digit wheel also brings a rotation of the gear by the same or different angle (translation) with it.
• At least one displaceable drive shaft is provided which can be transferred from an operating position in which the digit wheel can be set in rotation by the displaceable drive shaft into a removal position in which the displaceable drive shaft releases the dial wheel and the wheel axle.
• a displaceable drive shaft which may be arranged in particular pivotable or displaceable relative to the wheel axle, makes it possible to arrange drive shafts in areas of the numbering, which could not be occupied so far, to the simple and easy removability of the wheel axle without the need for individual drive components to disassemble from the numbering. In particular, this may e.g. be achieved by a wegklappbare or sliding drive shaft.
• the axes of rotation of the drive shafts lie on a segment of a circle when the displaceable drive shafts are in operating position. This is because the circular segment provides a particularly advantageous ratio between the area provided and the given extent. It is particularly preferred if the center of the circle, on the segment of which the axes of rotation of the drive shafts lie, lies on the axis of rotation of the number wheels.
• the circular segment covers an angular range> 180 °.
• the most complete possible encircling the wheel axis, which must however still allow the pressure of the set character combination, with drive axles advantageous to drive a minimum number of space with a minimum number of digit wheels can.
• the housing has a cover, and the displaceable drive shaft can be transferred to the removal position by opening the cover.
• displaceable drive shafts can be mounted in the cover, so that they can be removed by opening a cover rotatably connected to the housing or removing a cover which can be separated from the housing.
• a factory cover can be integrated in the lid.
• at least one rear gripper is provided for locking a digit wheel, which has a portion in the spaces between the teeth of the gear wheel associated with the digit wheel from the outside, ie from the tips of the teeth of the gear forth , at least partially intervenes. This configuration allows a compact design of the wheel axle and thus also contributes to make numbering as compact as possible.
• the gear performs a dual function: on the one hand, the transmission of the drive movement, in particular on the drive pinion and on the other hand, the exact positioning and holding the digit wheel by the Schureiokfer, in particular a linearly working rear gripper.
• This dual function makes it possible to minimize the space between the individual engravings on the dial.
• a preferred electromechanical relief device can be designed so that the rear grippers have a compression spring as Hintergreiferfeder, which is mounted in a base receptacle and that the base receptacle via an eccentric shaft for the entire series, parts of the series or individually lowered.
• the portion of the rear gripper which at least partially engages in the spaces between the teeth of the gear associated with the dial gear from the outside, a curvature having a radius greater than the radius of a curvature having the tips of teeth of the gear associated with the digit wheel, in particular greater than five times and the modulus of the toothing of the gear is substantially about half the radius of the rear gripper, since this configuration represents a suitable ratio of the driving force and positioning force and allows optimum wear behavior.
• each servo geared motor is provided in an advantageous numbering unit for driving each drive shaft, in particular being brought into harmony with a compact design, if it is arranged such that the axis of rotation of the rotor of the servo geared motor coincides with the axis of rotation of the respective drive shaft collapses.
• Particularly space-saving is such an embodiment, when the servo geared motors partially immerse themselves in the housing.
• Another space-saving measure that can be taken alternatively or cumulatively is that are arranged on two opposite sides of the housing servo geared motors for different drive shafts.
• a particularly advantageous controllable numbering is obtained when the number of teeth on the gear is an integer multiple of the number of digits of the respective number wheels.
• Another, cumulative or alternative to the above genann th embodiment providable possibility to obtain a simply controllable numbering is to provide that the total translation of the drive is integer divisible by the number of digits of the respective number wheels.
• an integrated electronics for controlling the numbering is arranged in the housing. It is particularly advantageous if a software control with an adaptive algorithm which monitors parameters of the numbering unit during operation and is provided with adaptive readjustment is made possible.
