Description

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. It is noted that the term "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.

In modern numbering systems, the number wheels are usually each individually adjustable and at least one digit wheel can be driven via a pinion gear associated gear. The numbering has for each connected to a drive unit digit wheel a drive shaft with a drive shaft connected to the drive pinion, so that a fast Setting a desired character combination is guaranteed. In most cases, at least some of these drive shafts are provided with a-possibly with the interposition of a gear-associated engine and controlled by a control electronics for the motors. However, this results in sources for further maintenance and repair, for example, when a motor fails, an electrical contact with a motor dissolves or an electronic component belonging to the control electronics fails.

In the customary use of such numbering machines, 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. This implies that the temporary failure of a numbering machine can affect the entire press. It is thus desirable that the user of the numbering system can remedy a malfunction occurring, if possible, quickly and on the spot, and in particular can easily replace a motor together with associated wiring.

In practice, this results in known numbering works, such as those from the EP 2 032 364 B1 are known, problems. It turns out that especially in very compact numbering, with which also digit sequences can be applied to crowded small formats, disassembly and proper assembly of the numbering often only by experts at the respective manufacturer of numbering with the required precision, the relative positioning of the Parts to each other with tolerances of less than one tenth of a mm required can be made.

The object of the invention is to make a numbering in the sense more compact than before, that more such numbering on a numbering with a given radius can be arranged as previously fast setting of the character combination to be printed allows.

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 unit according to the invention comprises a housing, and a numbering unit arranged at least in sections in the housing. In this case, the numbering unit has a wheel axis, on which a plurality of individually adjustable numbered wheels are rotatably arranged, wherein at least one of the number wheels can be driven via a gear assigned to the number wheel.

Furthermore, the numbering unit according to the invention comprises a drive module, wherein the drive module has a carrier and drive units for at least one of the number wheels drivable via a gearwheel.

In this case, the drive units each have a drive shaft, a drive pinion arranged on the drive shaft for driving the toothed wheel, and a motor which is connected directly or via a primary gear to the drive shaft, so that the drive shaft can be set in rotation by the motor. As a precaution, it should be noted that the drive pinion, even if it drives the gear via an intermediate gear, is suitable for driving the gear and is used.

It should also be noted that this formulation also includes the cases where the drive shaft is formed by the shaft of the motor or by the output shaft of the primary gear.

It should be noted in this connection that this description distinguishes between the terms "intermediate gear" and "pre-gear". Here, a "pre-gear" is understood to mean a transmission that is designed such that its output shaft is an extension of the shaft of the gear driving the motor, so that the output shaft and drive shaft rotate about the same axis of rotation, while transmissions in which the axes of rotation of the output shaft and Drive shaft offset from one another have to be referred to as intermediate gear.

Still further, the numbering invention comprises control electronics for controlling the motors.

The numbering mechanism is characterized in that the drive units are arranged offset relative to one another on the carrier such that at least some of the drive units project laterally beyond the carrier in the direction of extension of the wheel axis and the housing is a housing part which surrounds the bottom of the housing and at least two sections each of the sidewalls of the housing part is provided with a projecting portion, a straight portion, and a recessed portion in each of the sidewalls of the housing portion, the projecting portions of the one sidewall facing the recessed portion of the other sidewall; the straight portion of one side wall of the straight portion the other side wall and the recessed portion of the one side wall and the projecting portion of the other side wall are opposed to each other and geometrically adapted to each other so that the outsides of the side walls of two such housing parts can interlock.

Easy to maintain is the numbering, if the housing has a housing part in which on the one hand the numbering unit at both ends of the wheel axle and on the other hand the drive module stored such -d.h. are received in stock with designated sections of the numbering unit or the drive module, that their relative position is fixed to each other. Furthermore, it is provided that the numbering unit and the drive module can be removed as a complete assembly at least when a fixing device, for example a screw or a locking bolt, which prevents the falling out of the respective part when using the numbering unit in a printing press during operation ,

By summarizing not only the number wheels to the numbering unit, but also the components of the drive units in a drive module, which are each removable as an assembly from the numbering, while providing a single housing part on which both the numbering unit and the drive module are stored, the Maintenance of the numbering machine decisively simplified. The modular design with only a few components ensures that only a few components need to be positioned at the same time. In addition, by the common storage of these modules in a single housing part, the precise and reproducible positioning of numbering and drive module to each other, which for a stable and reliable operation of the Numbering is indispensable, even when assembling the numbering ensured by less experienced forces.

In a further development of the invention, the numbering unit and the drive module are mounted removably such that the direction in which the numbering unit can be removed and the direction in which the drive module can be removed are the same. In particular, if this direction is the one in which the letters of the numbering wheels of the numbering unit forming the respective serial number to be printed show, this measure makes it possible to disassemble the numbering unit into its assemblies in a small space. In addition, can be avoided by the latter embodiment that the entire numbering must be removed from the printing press, because then simply the numbering unit and the drive module can be removed in the radial direction relative to the printing cylinder of the printing press.

It has proved to be advantageous, in particular, if the control electronics are connected to the carrier of the drive module such that the drive units together with the carrier and control electronics can be removed together as an assembly. This simplifies maintenance work especially because then the cable connection between the motors of the drive units and the control electronics driving them does not have to be performed within the housing, where it is made difficult by very cramped space, but can be done outside of the housing.

In practice, it has been found that the control electronics have a considerable complexity, which means that their circuitry realization as a populated Circuit board can lead to an undesirable increase in space requirement. This applies in particular to arrangements in which at least one printed circuit board section of the control electronics is arranged below the drive units.

In order to prevent any ambiguity, in particular with regard to the meaning of the terms "top" and "bottom", it is pointed out that by definition the top of a numbering mechanism is the side on which the letters of the number wheels are exposed. According to conventional definitions, the underside of the numbering mechanism is the side opposite the top side of the numbering mechanism, that is to say the side with which the numbering mechanism is arranged, when used as intended, on the numbering shaft of a printing press. The direction in which the wheel axis of the numbering axis runs is defined as the transverse direction of the numbering unit; the longitudinal direction is the direction perpendicular to the transverse direction and the direct connection of the top and bottom of the numbering unit. It should be noted that this definition, which is based on the numbering machine geometry, results in that the transverse direction of vertically printing numbering units arranged on the numbering shaft of the printing press runs in a different direction than the transverse direction of horizontally arranged on the numbering shaft of the printing press printing numbering machines.

This space problem can be defused sustainably if the control electronics is divided into at least two populated printed circuit boards, which are connected to each other with a cable. However, then should also that the housing part, are stored in the numbering unit and the drive module, a recess for receiving this cable, since otherwise, the orientation of the drive module relative to the numbering unit can be influenced in unfavorable position of the cable so that the necessary precision and reproducibility of the adjustment is compromised.

Another difficulty in assembling known numbering machines is that there is no defined guidance for the cables, which are a necessary electrical connection between the motors on the one hand and the control electronics on the other hand. This problem can be alleviated by the fact that cables which connect the motors to the control electronics are mounted at least in sections through a gap between a side surface of the carrier of the drive module and a surface of the housing part facing the carrier of the drive module in which the numbering unit and the drive module are mounted. are guided. For the sake of completeness, it is pointed out that this presupposes that the drive module is mounted immovably even without the inclusion of the side surface in question.

It has been found that the assembly of the numbering after a maintenance process is greatly simplified when all the drive units are arranged on a single carrier, although it is expressly noted that a carrier with a hinged part, arranged on the one or more drive units are regarded as a single carrier. This is due to the fact that then only two modules must be adjusted relative to each other.

According to a particularly preferred embodiment of the invention, it is advantageous if the carrier on its numbering unit facing surface for each drive unit a Recess has, in the drive shaft, drive pinion and at least a portion of the motor are arranged, wherein the recess, except for locations where a holder for the drive unit is provided, extends over the entire extent of the carrier in the direction of extension of the wheel axis, said Surface of each recess has the shape of a segment of a shell of a cylinder whose axis coincides with the axis of rotation of the drive shaft and whose radius is adapted to the radius of the drive pinion, and wherein the individual recesses are arranged so that the axes of the surface defining cylinder and so that the axes of rotation of the drive shafts are arranged so that they lie on a circular segment. This form of the carrier leads in numbering, in which a drive of number wheels associated gears should be done without intermediate gear, so which engages around a coincident with the axis of rotation of the motor rotating drive pinion directly into the gear, to a particularly compact arrangement of the drive units, which is also inexpensive to produce by machining.

Furthermore, it has proved to be conducive to easy maintenance of the numbering, when the drive pinion directly engage in the driven by them gears of the numbering and offset in the direction of extension of the wheel axis of the numbering unit offset from each other. It has been found that the use of an intermediate gear brings about a further degree of freedom, which requires adjustment in order to ensure a low-friction and lossless engagement of the gears and thus complicates the maintenance.

In a further development of this embodiment, it is additionally provided that motors assigned to different gear wheels protrude differently far beyond the carrier in the extension direction of the drive shaft. This allows the mutually offset arrangement of the drive pinion despite the use of copies of a standardized drive unit assembly for all drive units, which not only contributes to a low-cost manufacturing, but also further reduces the risk of not sufficiently precise adjustment.

An increase in the installation space requirement caused by the above-described measure can be counteracted at least in part by arranging recesses in the housing for receiving sections of the motors projecting beyond the support.

• Einerseits zeigen bei dieser Anordnung nicht mehr die Anschlüsse für die Verbindungskabel zur Steuerelektronik bei allen Motoren in dieselbe Richtung, was die Übersichtlichkeit beim Anschluss der Motoren erhöht und eine geordnete Kabelführung erleichtert, was einem "Kabelwust" vorbeugt. Dieser Effekt ist besonders ausgeprägt, wenn eine Bauform mit zweiteiliger Steuerelektronik, wie sie bereits weiter oben beschrieben wurde, gewählt wird, da dann eine Zuordnung der Verbindungskabel der Motoren von allen Antriebseinheiten, die in derselben Orientierung angeordnet ist zu jeweils demselben Teil der Steuerelektronik möglich ist, was die Kabelführung weiter vereinfacht.

Furthermore, it has proved to be advantageous if arranged on the same support groups of drive units are rotated by 180 ° to each other. This brings two advantages:

• On the one hand, with this arrangement, the connections for the connection cables to the control electronics no longer point in the same direction in all motors, which increases the clarity when connecting the motors and facilitates an orderly cable routing, which prevents a "cable chaos". This effect is particularly pronounced when a design with two-piece control electronics, as already described above, is selected, since then an assignment of the connection cables of the motors of all drive units, which is arranged in the same orientation to each same part of the control electronics is possible , which further simplifies cable routing.

On the other hand assemblies of mutually rotated by 180 ° arranged drive units are therefore particularly useful because the space requirement dramatically increasing the need for a large offset between drive units that drive arranged at the opposite ends of the wheel axle gears, is circumvented by the corresponding drive units in the reverse orientation are arranged.

It is particularly preferred if the housing part in which the numbering unit is mounted at both ends of the wheel axle and the drive module comprises the bottom of the housing and at least two sections of opposite side walls of the housing.

According to an advantageous development of such a housing part, the portion of the housing part, which forms the bottom of the housing, a recess for mounting the drive unit by receiving the carrier. Such mounting of the drive module in the bottom of the housing part allows, despite precise positioning and mounting of the drive module between the sections of opposing side walls of the housing and the side surfaces of the drive module remains a distance for cable management or for receiving a carrier of the drive module superior Motors can be used.

A still further specialized embodiment of the invention provides that the shape of the recess is adapted to the shape of the portion of the carrier to be received in the recess for storage, that a pre-positioning in some sections of the carrier by direct contact between lateral wall of the recess and carrier , in particular in the sense of an insertion aid, or an exact positioning the support is ensured while in other sections of the carrier there is a gap between the carrier and the side wall of the recess for receiving at least one connecting cable between a motor and the control electronics. In this way, the space available inside the housing is increased in particular for the cable guide.
If the wall surfaces serve only for pre-positioning of the carrier in the housing part, it has proven to be expedient to bring about the exact positioning by the use of position pins.

According to the invention, the drive units are arranged offset on the carrier of the drive module such that at least one of them protrudes laterally beyond the carrier with a section, and in each case one of the side walls of the housing part the upper wall section viewed in the direction of pressure a projecting area a straight area and a The projecting portions of the one side wall of the recessed portion of the other side wall, the straight portion of the one side wall of the straight portion of the other side wall and the recessed portion of the one side wall and the projecting portion of the other side wall are opposite to each other and geometrically adapted to one another such that the outer sides of the side walls of two housing parts, which in practice belong to adjacent numbering works, can interlock. This makes it possible to make the numbering machine more compact in the sense that more such numbering machines can be arranged on a numbering shaft of given radius than heretofore.

The preferred housing for such a numbering is characterized in that the housing is a housing part with devices on the one hand for supporting a numbering unit at both ends of the wheel axle and on the other hand for supporting a drive module, wherein the relative position of the numbering unit and the drive module of the numbering mechanism is fixedly fixed to one another by the arrangement of the respective devices.

The drive module according to the invention for such a numbering has a support and at least some of the gear wheels driven by a gear drive units with a drive shaft, with a drive shaft connected to the drive pinion for driving the gear and with a motor, directly or via a primary gearbox with the drive shaft is connected so that the drive shaft through the motor is set in rotation on. It is preferably characterized in that the drive module as at least when a fixing device is released, completely configured from a numbering assembly is configured.

FIG. 1 shows an exploded view of Numberierwerks 100 with the modules numbering unit 110, drive module 140 and housing 180th

The numbering unit 110 has a wheel axle 111, of which in FIG. 1 only one bearing block 112 passing through end face can be seen, on, on which a plurality of individually adjustable numeric gears 113 are rotatably arranged. As for the in FIG. 1 the viewer nearest digit wheel 113 can be seen, at least this number wheel 113 is driven by a gear 114 associated with it.

The sectional view according to FIG. 2 Further insights into the structure of the numbering unit 110 can be found. In it you can see the entire wheel axle 111 with arranged at their ends bearing blocks 112,115, all the number wheels 113 and their respective associated gears 114th

The shape of the bearing blocks 112, 115 is matched precisely to bearing openings 182, 183 arranged in the housing part 181, so that the numbering unit 110 can be positioned exactly and without play by mounting in the housing part 181. The bearing blocks 112,115 also each have fixing means 116,117 in the form of screws, which can be brought into engagement with provided in the bearing openings 182,183 threaded holes 195,196. If the fixing means 116, 117 are released, then the numbering unit 110 can be removed from the numbering unit 100 as a complete assembly in the direction in which the letters of the numbering wheels of the numbering unit that form the respective serial number to be printed are shown.

This in FIG. 1 shown drive module 140 has a support 141 with a hinged portion 141 a, one of two electrically interconnected assembled printed circuit boards 146a, 146b existing control electronics 146 and seven drive units 143. Each of the drive units 143 is composed of a motor 143a, a power take-off gear 143b arranged on the engine, and a drive gear 143d arranged on the drive shaft 143c of the power take-off gear 143b, ie, its output shaft. How particularly good in the sectional view of FIG. 2 can be seen, engage the drive pinion 143d directly into the gears 114 and so when the motor 143a driven a movement of the gear 114 and the associated digit wheel 113 effect to bring a desired letter in printing position.

As in the illustration according to FIG. 1 it can be seen, the support 141 on its numbering unit 110 facing surface for each drive unit 143 has a recess 144 in which in particular the drive shaft 143c, drive gear 143d and at least a portion of the motor 143a are arranged. In the embodiment shown here, in which the drive units 143 also include the gearbox 143b, they are also located in the recess 144. Off FIG. 1 In particular, it becomes clear that the term "lying in the recess" is not to be understood as meaning that the recess completely surrounds the component lying in it, but that it is already sufficient if a partial section of the component dips into it.

In this case, the surface of each recess 144 has the shape of a segment of a shell of a cylinder whose axis coincides with the axis of rotation of the drive shaft 143c or slightly, that is displaced in the mm or sub-mm range parallel thereto, and its radius to the radius of the Drive pinion 143d is adapted so that its rotation is not hindered, the smaller the realized distance between the surface of the recess 144 and the teeth of the drive pinion 143d, the more compact the design becomes. In this case, the individual recesses 144 are arranged such that the axes of the cylinders defining their surface and thus also the axes of rotation of the drive shafts 143d are arranged such that they lie on a circular segment of an imaginary circle. Of course, this shape is not mandatory but modifiable; For example, stepped recesses would be conceivable.

The recesses 144 have, as in both FIG. 1 as well as in FIG. 2 can be seen, in each case holders 145 for the drive units 143, with which the otherwise extending over the entire extent of the carrier 141 in the extension direction of the wheel axis 111 recesses 144 are interrupted. Specifically, in this example, the drive units 143 are as particularly good at FIG. 2 can be seen, in the region of the drive shaft 143c, which is formed by the output shaft of the Vorschaltgetriebes 143b, held immediately behind the drive gear 143d.

How very good the FIGS. 1 and 4 can be seen are to realize the drive for the different number wheels 113 via the corresponding gears 114 of the numbering unit 110, the brackets 145 offset from one another and the drive units 143 divided into two groups. The two groups are arranged rotated by 180 ° to each other, so that the motor-side ends of the drive units 143 of the first group and the drive pinion side ends of the drive units 143 of the second group facing the viewer.

Like the same FIG. 1 can be seen, the control electronics consisting of two populated printed circuit boards 146a, 146b is arranged in each case in the longitudinal extent of the carrier 141 at the end faces, so that it can be removed together with this and the drive units 143 as an assembly from the numbering 100.

As in FIG. 2 can be seen particularly clearly, the two printed circuit boards 146a, 146b are connected to each other with a multi-core cable 147. Further, the motors 143a are each connected via a multi-core cable with one of the two populated printed circuit boards 146a, 146b, which is not shown for reasons of clarity.

The carrier 141 also has a threaded bore 153 and a positioning hole 154, which serve to position and fix the carrier 141 on the housing part 181 with a fixing means, in particular with a screw 155 screwed into or through the housing part 181.

As in FIG. 1 can be seen, the housing 180 has a housing part 181, which includes the bottom 181 a and two opposing side walls 181 b, 181 c of the housing 180. The housing part 181 is also in FIG. 4 once again, viewed from a different perspective.

In the housing part 181, as already mentioned above, bearing openings 182, 183 are arranged, on which the ends of the wheel axle 111 of the numbering unit 110 are mounted above the bearing blocks 112, 115. Furthermore, as is particularly good at the sectional view of FIG. 2 as well as the representation according to FIG. 3 can be seen in the bottom portion 181c of the housing part 181a a Recess 184 arranged in which a portion of the carrier 141 is mounted without play. In this way, in the housing part 181 on the one hand, the numbering unit 110 at both ends of the wheel axle and on the other hand, the drive module 140 is mounted such that their relative position is fixed to each other.

Special attention is in FIG. 2 the side surfaces 185, 186 of the recess 184 and the corresponding side surfaces 150,149 of the portion of the carrier 141, which is arranged in the recess 184, to give. The side surfaces 185, 186 have mutually opposite bevels, so that the recess 184 widens in the direction of the numbering unit 110. While the portion 150a of the side surface 150 of the carrier 141 corresponding to the side surface 185 of the recess 184 is adapted to this profile in the region of the cut surface, the portion 149a of the side surface 149 of the carrier 141 is perpendicular to the bottom portion 181c at this point, so that a gap 187 between carrier 141 and the side surface 186 of the recess 184 consists. This provides space for the routing of the cables, not shown, between motors 143a of the first group of drive units and populated circuit board 146a.

The side surface 149 of the carrier 141 is adapted in a second portion 149 b to the profile of the side surface 186 of the recess 184 so that they provide at least one insertion aid when inserting the drive module 140 in the housing part 181. In principle, it would be possible by a precisely fitting design of the mating surfaces in this way to avoid tilting of the carrier 141, in the embodiment shown here, this is how particularly well in FIG. 3 can be seen, however, by the provision of positioning pins 202,203, which engage in holes on the underside of the carrier 141 reached.

For this, in the region of section 149b, on the opposite side of support 141 there is a section 150b of side face 150 perpendicular to bottom section 181c, instead of following the course of side face 185 so that there is an unillustrated gap, the space for the guide the in FIG. 2 cable 148, not shown, between motors 143a of the second group of drive units and populated circuit board 146b.

In the bottom of the recess 184, a further recess 198 for receiving the cable 147, which connects the two printed circuit boards 146a, 146b, arranged.

How to be particularly good in FIGS. 1 and 3 1, the side walls 181b, 181c formed by the housing part 181 have recesses 199, 177 which serve to receive portions of motors 143a protruding beyond the edge of the carrier 141 in the transverse direction of the numbering unit 100.

The two not formed by the housing part 181 side walls of the housing 180, as in FIG. 1 can be seen, formed by two bolted plates 188.189, wherein in the plate 189, an opening 190 is provided through which an arranged on the printed circuit board 146b interface connector 152 of the control electronics for supplying the same with operating voltage for the control electronics and controlled by them motors 143a and / or control data is led out of the housing 180.

The housing is completed by a lid 192 rotatable about an axis of rotation 191 and having an opening 193 through which the letter combination of numbering unit 110 to be printed when the lid is closed and which can be fastened with screws 194 in its closed position.

Another peculiarity of the illustrated embodiment of the numbering device, which represents an independent invention, is that, as in particular from the Figures 3 and 4 is shown, in each of the side walls 181b, 181c of the housing of the viewed in the direction of pressure upper wall portion each have a projecting portion 201a, 202a, a straight portion 201b, 202b and a recessed portion 201c, 202c is provided. In this case, the areas 201a and 202c, 201b and 202b and 201c and 202a face each other and are geometrically matched to each other so that the outer sides of the side walls 181b, 181c of two housing parts 181 can engage, as in FIG. 5 is shown for three numbering plants.

How to do that FIGS. 4 and 5 This results in a particularly compact design of the numbering machines and the possibility to arrange as many numbering 100 on a numbering shaft with a given radius. By the projecting portions 201a, 202a, the possibility is created, drive units 143 to be arranged so that they protrude laterally beyond the carrier 141 of the drive module 140. Because of this lateral offset can be saved on the respective opposite wall portions 202c, 201c by their recessed configuration space.
