Definitions

  • the invention relates to a numbering device, in particular for use in printing machines with the features of the preamble of claim 1.
  • Numbering devices have long been used, in particular, to print individual alphanumeric character combinations on documents, for example the serial numbers of banknotes, securities or checks. This results in the need to change the character combination by rotation of at least one numbering wheel between printing processes. Although there has been an increasing use of partially or fully motorized numbering machines in recent years in which this rotation is effected by motors, the mechanically effected adjustment of the numbering wheels still plays an important role.
  • a long-established approach to effecting the mechanical adjustment is to use an interaction of coaxial laterally serrated gripper discs with a smaller diameter than the diameter of the numbering wheels with a comb-like member having different length teeth, the so-called front gripper ,
  • the front gripper is acted upon by a spring force applied to the so-called crank.
  • the crank which can be performed, for example, as a U-shaped bracket, which is pivotally mounted in the numbering device, is initially moved during the switching process such that teeth of the front gripper in contact with the respective gripper disks engage behind the next tooth of the gripper disk. Thereafter, the crank is returned mechanically, wherein the teeth of the front gripper which are in contact with gripper discs displace the gripper disc and the numbering wheels connected thereto.
  • the mechanical movement of the crank can be achieved for example by drive lever and / or by the use of a switching curve.
  • the purpose of the different length teeth of the front gripper is that they allow in conjunction with a corresponding design of the gripper discs to advance certain number wheels at certain times. For example, if a sequential numbering in the decimal system to be effected, instead of the teeth of the gripper disk of the numbering wheel for the one-digit, in which the front gripper engages with its longest tooth when the numbering wheel is to be turned to zero in the next movement, one greater depth can be provided. As a result, the second longest tooth of the front gripper, which interacts with the serration of the gripper disk of the number wheel for the tens position, comes into contact with the gripper disk associated with it precisely when the numbering wheel for the one position is rotated from the numeral nine to the zero digit becomes. Accordingly, only in this case - as desired for the consecutive numbering - the numbering wheel for the tens place further rotated.
  • This principle can be analogously transferred to the hundredth place, the thousands place, and so on. It is only essential that the recess of the gripper disc, which is assigned to the switching to the digit zero or nine of the respective location is so deep that the respective tooth of the front gripper can dive far enough into it, that even the shortest tooth of the front gripper in Contact with its associated gripper disc numbering wheel for the highest point can come when all other teeth of the front gripper engage in the corresponding zero digit recess of their gripper disc.
  • An example of such a numbering device is the example DE 1 001 290 refer to.
  • the play that is necessary in itself also has a particularly negative effect, since it brings with it that partly the full interaction surface between the teeth of the gripper disk and the tooth of the front gripper is not used, so that the contact force of the spring, which grips the front gripper against the gripper disk presses, acts on a smaller surface and thus increases the contact pressure and thus the wear effect. Accordingly, over time, uneven wear of the inter-engaging surfaces of the gripper disc and front gripper teeth may result, leading to local pits and protrusions.
  • the object of the invention is to provide a numbering in which the interaction between gripper discs and front gripper is improved so that the wear, in particular asymmetric wear, the teeth of gripper disc and front gripper is reduced.
  • the numbering device according to the invention has a plurality of numbering wheels arranged next to each other on an axis, which, when rotated to a printing position, can be used to print symbols. At least one of the numbering wheels of the numbering device has a first gripper disk connected to the numbering wheel and having a tooth structure. Furthermore, a front gripper is provided, i. a comb-like structure with teeth, at least one of which engages the tooth structure of a first gripper disc of one of the numbering wheels.
  • the advancement of a numbering wheel is effected by the interaction of the front gripper, more precisely by the tooth of the front gripper associated with the gripper disk of this numbering wheel, with the tooth structure of the gripper disk.
  • the front gripper is brought into a second position, in which this tooth of the front gripper engages in a second, usually adjacent one Deepening of the tooth structure of the gripper disc is located.
  • this part of the movement of the front gripper is performed so that the lying between the recesses tooth of the tooth structure of the gripper disc can be overcome without a movement of the gripper disc zugeordenten numbering takes place during the return movement of the front gripper from the second position to the first Position of this tooth ensures the entrainment of the gripper disc in the movement of the front gripper, so that a rotation of the data associated with the gripper disc numbering wheel, which allows the pressure of another arranged on the outer circumference of the Zahlierrads character.
  • At least one of the numbering wheels having a first gripper disc connected to the numbering wheel has a second gripper disc on the side opposite the first gripper disc
  • the front gripper has two for at least one numbering wheel which has a second gripper disc on the side opposite the gripper disc Having teeth, one of which when adjusting the numbering with the first and second gripper disc in the tooth structure of the first gripper disc numbering with first and second gripper disc and the other when adjusting the Zahlierrads with first and second gripper disc in the tooth structure of the second gripper disc numbering with first and second gripper disc engages.
  • the tooth structure of the second gripper disk is identical to the tooth structure of the first gripper disk and oriented exactly like this, and that the teeth of the front gripper, one of which is in the tooth structure of the first gripper disk of the numbering wheel with first and second Gripper disc and the other engages in the tooth structure of the second gripper disc numbering wheel with first and second gripper disc are the same length.
  • FIG. 1 shows a frontal view of an inventively constructed numbering device 100.
  • a support structure 101 for arranging the numbering device 100 on a printing press, not shown.
  • the support structure carries a substantially U-shaped housing with side walls 102, 103 and a bottom portion 104.
  • the side walls 102, 103 form the bearings for an assembly 105, which in FIG FIG. 2 is shown separately.
  • the assembly 105 has an axis 106, the outer ends, as particularly well with reference to the in FIG. 3 shown side view of the numbering device 100 are mounted in the side walls 102,103 when the assembly 105 is installed in a numbering device 100.
  • the axis 106 defines the common axis of rotation for the individually rotatable numbering gears 107a, 107b, 107c, 107d, 107e.
  • the axle 106 carries the crank 108, which in this example is designed as a frame whose longitudinal sides 109a, 109b extend parallel to the axis 106, whose transverse sides 110a, 110b extend perpendicular to the axis 106, in whose interior the numbering wheels 107a-107e are arranged and which is rotatably mounted on the axle 106.
  • a drive lever 111 is arranged, alternatively, a plug-in lever could be provided, which engages in the crank.
  • a front gripper 112 with teeth 112a, 112a ', 112b, 112c, 112d, 112e is rotatably mounted about an axis parallel to the longitudinal side 109b of the frame, which is mounted in the transverse sets 110a, 110b.
  • the front gripper 112 is biased toward the numbering wheels 107a-107e by the force of a spring 113, so that the radial distance of the teeth from the axle 106 against the force of the spring 113 can be increased.
  • the front gripper 112 has more teeth than mechanically directly driven numbering wheels are present and also two equal-length teeth 112a and 112a ', which, as will be explained in more detail, interact with both sides of the numbering gear 107a arranged gripper discs 114a, 114a' ,
  • This, essential for the invention facts is particularly good in the detailed representation of FIG. 5 which only shows the front gripper 112 with its teeth 112a to 112e and the numbering wheel 107a with its gripper discs 114a, 114a '.
  • the tooth structure of the gripper discs 114a and 114a ' is identical and identically oriented, which means that they are designed mirror-symmetrically to the center plane of the numbering gear 107a, which is perpendicular to the axis of rotation.
  • the further teeth 112b-112e of the front gripper become progressively shorter from the tooth 112b to the tooth 112e, and interact with gripper discs of numbering gears 107b to 107e having only one gripper disc, respectively.
  • the principle that is used for indexing the numbering wheels 107a-107e by means of the crank 108 effected changes in the position of the front gripper 112, can be particularly well using the example of the numbering gear 107a on the basis of FIG. 4 , which shows a sectional view through the numbering device 100.
  • the operating principle is the same for the other numbering wheels:
  • a gripper disc 114a is arranged, which is rotatably connected to the numbering gear 107a.
  • This can be realized in particular by the fact that the gripper discs are each made in one piece with the numbering, but it can also be provided separate numbering wheels and gripper discs and then connected to each other, for example, welded, glued or pinned.
  • the gripper disc 114a has a tooth structure with teeth 115 and depressions 116 and a particularly deep depression 117, which is so deep that it can accommodate the gripper disc associated tooth of the front gripper 112 so far that the shortest tooth of the front gripper 112 on the tooth structure the gripper disk assigned to it can abut, whose toothing therefore does not have to have a particularly deep recess.
  • the teeth 115 are designed with asymmetrical tooth flanks 115a, 115b, so that the depressions 116, ie the interdental spaces, are asymmetrical.
  • the tooth flank 115a rises relatively gently in the direction opposite to the direction of rotation, while the tooth flank 115b slopes steeply in this direction.
  • a rear gripper 120 which is acted upon by the force of a compression spring 118 and rotatable about an axis 119, engages in one of the recesses 116.
  • the drive lever 111 In the in FIG. 4 the drive lever 111 is in its upper position, which causes the end of the crank 108, on which the front gripper 112 is arranged, is guided down and the tooth 112 a of the front gripper 112 near a steep tooth flank 115 b in a recess 116th intervenes.
  • the drive lever 111 is moved down, and the frame-shaped crank 108 is rotated about the axis of rotation, the front gripper 112 rises.
  • the tooth 112a remains hanging on the steep tooth flank 115b, whereby the numbering gear 107a is rotated to the next printing position.
  • the rear gripper 120 is thereby pushed back by a gently rising tooth flank 115 a against the force of the compression spring 118 until it slips into the next recess 116.
  • the teeth 112a-112e of the front gripper 112 are of different lengths, in this way only the numbering wheel 107a is rotated, as long as the tooth 112a of the front gripper 112 does not engage in the particularly deep recess 117. In this case, the next shorter tooth of the front gripper 112 comes into contact with the gripper disk associated with it, moves it and takes over the control of the movement of the front gripper 112.
  • the numbering wheel 107a which has a gripper disc on both sides, can also be assigned a back gripper 120a, 120a 'for such numbering wheels with gripper disc on both sides of each gripper disc.
