US 8225714 B2Abstract
There is described a numbering system for carrying out numbering in a printing press comprising a numbering cylinder, a rotatable shaft defining a rotation axis, at least one supporting disc mounted on the rotatable shaft for rotation therewith, the supporting disc comprising a peripheral mounting ring for mounting of at least one numbering device (1.06; 2.06) on a periphery of the supporting disc, which numbering device (1.06; 2.06) is secured to the peripheral mounting ring (1.43) by means of a clamping mechanism. The peripheral mounting ring (1.43) has a T-shaped cross-section defining a pair of annular mounting grooves (1.43 a, 1.43 b) on each side of the peripheral mounting ring (1.43). The numbering device (1.06; 2.06) comprises clamping elements (1.50; 2.50) on each side of the numbering device (1.06; 2.06) which are adapted to cooperate with the annular mounting grooves (1.43 a, 1.43 b) for securing the numbering device (1.06; 2.06) onto the peripheral mounting ring (1.43). The clamping elements (1.50; 2.50) are preferably spring-loaded clamping elements.
“This application claims the benefits under 35 U.S.C. 119(a)-(d) or (b), or 365(b) of International Application No. PCT/IB2007/053146 filed Aug. 8, 2007, and European Patent Application No. 0611898.7 filed Aug. 16, 2006” and European Patent Application No. 06124668.2 filed Nov. 23, 2006.
The present invention generally relates to the mounting of numbering devices onto numbering cylinders as used in particular for carrying out numbering of printed documents, especially banknotes or the like securities.
Numbering presses for carrying out numbering of printed documents are already known in the art. Such a numbering press is for instance disclosed in German patent application No. DE 1 486 894 or European patent application No. EP 0 061 795. FIG. 1 is a drawing taken from European patent application No. EP 0 061 795 which schematically illustrates a numbering press.
In instances where mechanically-autonomous electronic numbering devices are used, such mechanical actuation means might not at all be necessary. This is for instance the case of the numbering device disclosed in European patent application No. 06115994.3 filed on Jun. 23, 2006 in the name of the present Applicant and entitled “NUMBERING DEVICE FOR TYPOGRAPHIC NUMBERING”.
Further numbering devices are also disclosed in U.S. Pat. No. 4,677,910, International application No. WO 2004/016433, German patent application No. DE 30 47 390, U.S. Pat. No. 4,843,959, International application No. WO 2005/018945, as well as European patent application No. 05405375.6 filed on Jun. 8, 2005, which is now European Patent No. 1 731 324 A1, in the name of the present Applicant and entitled “NUMBERING PROCESS FOR SECURITIES, METHOD FOR PROCESSING THE NUMBERED SECURITIES AND NUMBERING DEVICE TO CARRY OUT THE NUMBERING PROCESS”.
An aim of the invention is to improve the known devices.
FIG. 3 is a partial perspective view showing the mounting of a numbering device, designated globally by reference 1.06, onto the supporting disc 1.42 of a numbering cylinder according to one embodiment of the invention. The remainder of the numbering cylinder is not shown in FIG. 3. One will however understand that, except for the mounting system for the numbering device 1.06, the configuration of the numbering cylinder remains similar to that illustrated in FIG. 2, i.e. it comprises a rotatable shaft defining a rotation axis onto which shaft the supporting disc 1.42 is mounted for rotation therewith, it being further understood that additional supporting discs are distributed along the rotation axis of the numbering cylinder in a number equal to the number of columns of prints on the sheets or web portions to be numbered.
One will not describe the configuration of the numbering device 1.06 per se and of its functioning any further as it is not of particular relevance within the scope of the present invention. It suffice to understand that the numbering device 1.06 comprises, located at its upper portion, a set of rotatable numbering wheels as schematically illustrated in FIG. 2. This numbering device 1.06 can be any type of numbering device, such as a mechanically-actuated numbering device requiring mechanical actuation means (as discussed in reference to FIG. 2) or a mechanically-autonomous electronic numbering device requiring no such mechanical actuation means, as disclosed in European patent application No. 06115994.3 filed on Jun. 23, 2006 in the name of the present Applicant and entitled “NUMBERING DEVICE FOR TYPOGRAPHIC NUMBERING”.
FIGS. 7 to 10, 11 a and 11 b illustrate another embodiment of the invention for securing a numbering device, designated in this other example by reference numeral 2.06, onto the peripheral mounting ring 1.43 of the supporting disc 1.42. As before, only relevant parts of the numbering device 2.06 are shown in FIGS. 7 to 9, namely a housing 2.60 thereof comprising two side frame parts 2.61 and 2.62 secured to each other (for instance by screws not illustrated). The actual configuration of the numbering device 2.06 per se and its functioning will not be described as these are not of particular relevance within the scope of the present invention. It suffice to understand that the numbering device 2.06 comprises, located at its upper portion, a set of rotatable numbering wheels (not illustrated in FIGS. 7 to 9) as schematically illustrated in FIG. 2. This numbering device 2.06 can again be any type of numbering device, such as a mechanically-actuated numbering device requiring mechanical actuation means (as discussed in reference to FIG. 2) or a mechanically-autonomous electronic numbering device requiring no such mechanical actuation means, as disclosed in European patent application No. 06115994.3 filed on Jun. 23, 2006 in the name of the present Applicant and entitled “NUMBERING DEVICE FOR TYPOGRAPHIC NUMBERING”.
As illustrated in FIGS. 8, 9 and 10, an inner surface 1.43 c of the head part of the peripheral mounting ring 1.43 of the supporting disc 1.42, which inner surface 1.43 c cooperates with a corresponding surface 2.51 c of the hook portion 2.51 a (see FIGS. 7, 9 and 10), is preferably conical with a positive opening angle θ (theta) with respect to the axis of rotation of the numbering cylinder onto which the supporting disc 1.42 is mounted (as schematically illustrated in FIG. 10). The corresponding surface 2.51 c on the hook-portion 2.51 a of the lever 2.51 is similarly conical so as to substantially match the curvature of inner surface 1.43 c. When designing the clamping system of FIGS. 7 to 10, it is advantageous to follow the design rules which will now be briefly discussed in reference to FIGS. 11 a and 11 b. FIGS. 11 a and 11 b are schematic side view of the clamping system respectively in a so-called clamping or rest state (i.e. when no pulling force is applied on the numbering device) and retaining state (i.e. when a pulling force is applied on the numbering device), where reference a1 designates an axis intersecting the axis of shaft 2.52 and the contact point C between the contact surface 2.51 c of the hook portion 2.51 a and the inner surface 1.43 c of the peripheral mounting ring 1.43 (which axis a1 can also be referred to as the “lever axis”), reference a2 designates a vertical line intersecting the contact point C (which vertical is perpendicular to the axis of rotation of the numbering cylinder onto which the numbering device is mounted), reference a3 designates a perpendicular to the inner surface 1.43 c of the peripheral mounting ring 1.43 intersecting the contact point C, angle α (alpha) is the angle between axes a1 and a2, and angle β (beta) is the angle between axes a1 and a3. It shall be understood that, angle θ (theta) in FIG. 10 correspond to the difference β−α of angles α and β.
An additional factor to be considered in the design of the clamping system of FIGS. 7 to 10 is the coefficient of friction cf existing between contact surface 2.51 c and inner surface 1.43 c. In the context of static friction, i.e. when there is no relative displacement between two bodies in contact, as in the present case, the coefficient of friction (cf) is equal to the ratio FF/FN of the force of friction FF between the two bodies and the force FN pressing them together, i.e. the force normal to the contact surface between the bodies. The coefficient of friction cf can thus alternatively be expressed as an “angle of friction” γ (gamma), where cf=FF/FN=tan(γ).
In the illustration of FIG. 11 a, i.e. in the clamping or rest state, the extremity of the lever 2.51 is pushed towards the inner surface 1.43 c of the peripheral mounting ring 1.43. The resulting force of friction FF1, which is proportional to the normal force FN1 along axis a3, will thus be directed opposite the direction where the lever 2.51 is pushing as illustrated in FIG. 11 a. The force FR1 produced by the lever 2.51 (i.e. by the combined result of forces F1 and FA1, which latter force FA1 corresponds to the generated force along the axis a1 of the lever) is directed along a thus defined axis a4 (or “axis of friction”) which forms a positive angle γ (i.e. corresponding to the arctangent of cf, namely a tan(cf)) with respect to axis a3.
F R1 =F 1/sin(β+γ) (1)
F U1 =F R1�cos(β+γ−α) (2)
F R2 =F 1/sin(β−γ) (3)
F U2 =F R2�cos(β−γ−α) (4)
In the context of the embodiments of FIGS. 7 to 10, 11 a and 11 b, as four clamping elements 2.50 are used, the overall force in the clamping state (which can be referred to as the “clamping force”) will be four times FU1, while the overall force in the retaining state (which can be referred to as the “retaining force”) will be four times FU2. From looking at FIG. 11 b and at expression (4) above, it will be understood that the retaining force will be optimum when force FR2 is directed along the vertical axis a2, i.e. when the following equation is satisfied:
