Abstract

The unit has a heating device provided in an interior region of a working cylinder (1) that carries a printing or embossing stencil (14) on circumference (16) of the cylinder to emboss or print. A web (5) is made from a flat material that is conveyed between the working cylinder and a back-pressure cylinder. The stencil extends over a part of circumference of the working cylinder, and is held on the working cylinder by fastening devices (12, 13). A clamping ring (15) acts on a circumferential edge of the stencil and clamps against the working cylinder.

Description

  • The invention relates to a printing or embossing work with the features of the preamble of claim 1, and to a working cylinder with the preamble features of claim. 9
  • Such printing or embossing is for example from the EP-A-1 393 904 known. In this case, a plurality of matrices in the axial direction and circumferentially offset to a working cylinder by means of pins or screws and by means of oblique peripheral edges of the die attacking wedges attached. This type of attachment is not always reliable and also relatively cumbersome to create.
  • The invention is therefore based on the object to find a simpler attachment system for circumferentially divided matrices and this is achieved by the characterizing features of claim 1. According to the invention, therefore, only the clamping ring needs to be pulled over the peripheral edge, expediently two at opposite peripheral edges of the pressure - or embossing die attacking clamping rings are provided.
  • In the prior art, it was necessary to relatively rigidly connect the respective die with the working cylinder. However, in view of the fact that this cylinder is heated and therefore thermal expansions arise, it is more advantageous if according to the invention the fastening device has holes of the respective printing or embossing die passing through pins, preferably one in the circumferential direction relative to the other staggered pin, wherein at least one of Holes in the circumferential direction is greater than the cross section of this pin passing through this hole.
  • If, in the context of this invention, a "clamping ring" is mentioned, it may be formed in a variety of ways, for example, with a suspension enabling, approximately parallel to the axis of the working cylinder or obliquely extending slot. However, it is preferred if the thermal expansion itself is utilized for the clamping, and for this purpose it is advantageous if at least one of the clamping ring spanned parts, that is the working cylinder and / or the printing or embossing die, made of a material with a larger, eg by at least 25% larger, thermal expansion coefficient than that Material of the clamping ring consists.
  • This results in an automatic, which applies voltage to the parts only when the cylinder or the printing or embossing unit is in operation and heated, while in the other case, the voltage is automatically released.
  • This can be realized so that the clamping ring consists of a steel, in particular a tool steel, on the other hand, the pressure or embossing die of a non-ferrous metal, in particular of brass and / or so that the clamping ring consists of a tool steel, however, the working cylinder of chrome steel , It should be mentioned here that said pairing of materials of different thermal expansion coefficients can also be achieved with other materials, for example by using aluminum. However, the preferred chrome steel for the power cylinder of greater strength and therefore more suitable for the present purposes.
  • Further details of the invention will become apparent with reference to the following description of a schematically illustrated in the drawing, preferred embodiment. Show it:
  • Fig. 1
    a schematic view of a printing or embossing;
    Fig. 2
    an enlarged perspective view of working cylinder and impression cylinder;
    Fig. 3
    a section through a printing or embossing die in contact with the surface of the working cylinder and held by two clamping rings; and
    Fig. 4
    a perspective view of a printing or embossing die with mounting holes or pins.
  • According to Fig. 1 schematically is a simple printing or embossing with a working cylinder 1 and a counter-pressure cylinder 2 behind a bearing plate 3 with a (in Fig. 2 indicated) carried by the bearing plate 3 bearing block. The bearing plate 3 rests on an approximately T-shaped bracket 4. A to be printed or to be embossed band 5, based on Fig. 1 , deducted from the left of a supply roll, not shown, runs over a deflection roller 6 between the working cylinder 1 and counter-pressure cylinder 2 and (not shown) on the right side via a further deflection roller 7 to a take-up reel, as known, deducted. It is clear that the web 5 is only an example and that, if appropriate conveyors, individual sheets may also be embossed or printed if necessary, where the term "web" of sheet also includes such sheets.
  • The printing or embossing is carried out in a known manner by means of a cylinder attached to the, in Fig. 2 More clearly shown, printing or embossing die on a printing or embossing film 8, which runs in the same direction from a supply roll 9 and, for example, a to be printed on the tape 5 pattern, a film to be transferred or the like, which pattern or the like in the passage between the Cylinders 1 and 2 is hot transferred to the belt 5, whereupon the blank printing or embossing foil 8 is pulled upwards, for example, sucked into a collecting container 10 and thereby optionally comminuted.
  • Fig. 2 shows the relationships of the working cylinder 1 and impression cylinder 2 in a perspective view. In this case, the working cylinder is heated in a manner not shown here, but known per se, which preferably takes place in the manner described in claim 22 of the German patent application no. 10 2005 054766 is described, namely by a stationary, serving essentially as an axis heating cartridge, which passes through an opening 11 of the working cylinder 1.
  • The working cylinder 1 has, for example for the printing of labels, at its periphery on a series of raised printing or embossing dies 14 which in Fig. 2 partially shown as separate parts. Each of these printing or embossing matrices 14 has the printing pattern - here the letters PGS - raise, ie from the Matrizenmaterial prominent on - on. Since each of these matrices 14 extend only over part of the circumference of the working cylinder 1, it is necessary to fix them in their position relative to the working cylinder 1. For this purpose, two measures are preferably provided. On the one hand, each of these printing or embossing dies, which only reach over a partial region of the circumference of the working cylinder 1, has fixing holes 12 into which fixing pins 13 engage. Fig. 4 shows this training on a larger scale. Thereafter, it can be seen that the fixing holes 12 are slightly larger than the diameter of the pins 13. Conveniently, only one of the fixing holes 12a is larger, namely as a slot, formed so as to compensate for thermal expansion can. This Fixierloch- / Fixierstift arrangement serves so only the attachment of the die 14 in the circumferential direction. In contrast, it is held in the axial direction in each case by a clamping ring 15, which expediently engages a thinned edge piece 16 of the die. On the other hand, it is clear that in place of the fastening device 12, 13, or instead of the pin 13, be provided only a hook can, whereas the mating 12a, 13 secures the mobility due to thermal expansion along the circumference of the working cylinder 1.
  • Fig. 3 shows the conditions on a larger scale. While the die 14 abuts the surface of the working cylinder 1 and by means of Fig. 4 apparent fastening arrangement 12, 13 is fixed in the circumferential direction, are pushed on at least one side, preferably on both, each a clamping ring 15 on its edges 16. This is particularly facilitated by the fact that in the unheated state of the working cylinder 1 between the inner diameter of the clamping ring and the outer diameter of the working cylinder 1 is preferably a gap s. A small, not shown here, gap may also exist between the outer diameter of the respective edge 16 and the inner diameter of the attacking on this edge 16 portion of the clamping ring 15.
  • Now, an "automatic" attachment of the clamping rings 15 on the working cylinder 1 and / or on the die 14 can be obtained in that the thermal expansion coefficient of the clamping rings is selected to be lower than that of the working cylinder 1 and / or the die 14, e.g. at least 25% lower. If, for example, the clamping ring 15 consists of a steel, in particular a tool steel, on the other hand the pressure or embossing die 14 of a non-ferrous metal, in particular of brass, then the latter is under the effect of heating the working cylinder 1 and the heat transfer to the die 14th Stronger stretch than the clamping ring, so that this clamps the edges 16 properly. On the other hand results in a combination of material of clamping ring 15 of tool steel and cylinder 1 of chromium steel a greater expansion of the working cylinder in the radial direction, whereby the gap s is reduced, or instead of the clamping ring 15 is stuck to the surface of the working cylinder 1. Expediently, both measures, namely utilization of the greater thermal expansion of the die 14 and the working cylinder 1 with respect to that of the clamping ring 15, are jointly exploited.
  • As such, other materials with similar thermal expansion properties could be used, such as an aluminum working cylinder 1; however, it is off Fig. 2 it can be seen that a plurality of matrices 14 can be provided in the axial direction of the working cylinder 1, so that several labels are next to each other by transferring a medium 17, such as a gold foil, in the region of the raised letters ("PGS") on a flat substrate or to receive a web 5. In this case, each circumferential row of dies 14 is separated axially by a spacer ring 19 from the adjacent die 14. It is clear that the counter cylinder 2 has either matrices 14a complementary to the dies 14, which thus have depressions where the dies 14 have elevations (for relief embossing), or the counter cylinder 2 has a yielding surface (for printing or gold embossing) , in which the elevations of the dies 14 press.
  • From the above, it is also clear that after switching off the printing or embossing and after cooling of the working cylinder 1, the clamping rings 15 automatically release the edges of the dies 14 and / or the working cylinder 1 again and therefore can be easily removed again.
