Definitions

  • Cans as packaging are well known. They can be made of various materials such as sheet metal, wood, plastic. Tin cans can be made of various metals, such as aluminum, steel, brass. The can can be made from the metal sheet by cutting, folding, grouting or soldering or welding. Another possibility is cold forming, in particular deep drawing. This eliminates the joining of sheet edges.
  • a can can be closed by a lid.
  • Lids are conceivable in many different versions: there are hinged lid (cigar box), screw cap (oil can), plug (tea, biscuit or Niveadose).
  • the lid can also be firmly connected to the can, as in a tin can.
  • Tin and / or lid are often designed for promotional purposes.
  • the wall material can be coated with paint and paint, polished, labeled and / or embossed, depending on the manufacturer's request.
  • an inner coating with paint and paint, metal or plastic can be provided.
  • Cans can have many conceivable shapes: they can be rectangular, oval, round, octagonal, star-shaped or irregular (for example cat “Garfield”, mouse “Mickey”).
  • tins Most practical tins have a right angle between the bottom of the can and the wall, minimizing the space required to ship a variety of cans in a carton. In contrast, the lid is often not topside plan, but more or less strongly curved.
  • the subject of this invention are cans whose lids are designed and embossed multicolored, in particular lacquered and printed lids with lettering, which is both multicolored, as well as highlighted by embossing.
  • the invention relates Lids deep-drawn in aluminum, round, curved and mass-produced.
  • Such a tool is driven by a crankshaft and allows the production of 200 covers per minute. For each stroke, a lid is punched out of a metal sheet and then deep-drawn. The remaining edges on the edge of the lid are rolled so that the finished lid can be blown out.
  • FIG. 1 A suitable tool is shown in Figure 1. The movements of the tool during a cycle are also shown. The figure shows both the principle of a conventional, as well as a cycle according to the invention.
  • the tool consists of a lower tool (1), (2), (3) and an upper tool (4) and (5).
  • the lower tool has a core (1), a cutting ring (3) and a so-called fold holder (2).
  • the fold holder (2) has a roll ring (2a) on the upper side facing the core (1).
  • the upper tool consists of a punch (4) and an ejector (5) around which the punch (4) is oriented.
  • Such a combination of upper and lower tool is shown in Figure 1.
  • the upper tool is driven by a crankshaft. At top dead center (0 °), the top tool is in its highest position during a cycle.
  • a modern machine allows about 200 strokes per minute, so that about 12,000 lids per hour can be molded with a tool. Typically, 3 to 5 tools are used simultaneously, producing 36,000 - 60,000 lids per hour.
  • the metal sheet must be guided very precisely under the tools located at top dead center.
  • the drawing gap ie the distance between core (1) and fold holder (2), is exactly sheet thickness. This is not a trivial task for the tools, which are exposed to quite heavy and high dynamic loads. Therefore, conventional upper tools are usually rotatably arranged because this greatly facilitates the alignment of the upper tool with the lower tool for setting a correct drawing gap.
  • the ejector (5) is a heavily stressed tool part. This has various holes, which are a fastening, disassembly and ventilation of the plant tool allows. Conventionally, the holes and ventilation holes in the ejector (5) are distributed over almost the entire ejector (5). As a rule, 8 - 12 holes are provided.
  • This area represents a further clamping area of the tool, which is required for receiving the compression forces during rolling between the core (1) and the ejector (5).
  • the lid must be shaped again separately in a subsequent method step after ejection from the cutting-pull rolling tool. It is relatively problem-free, if the embossing does not have to be aligned when z. B. on a monochrome lid simply embossing any orientation should be done.
  • the free rotation of the upper tool which is required for aligning the upper tool on the lower tool, does not permit the projection of a lettering because the rotation can result in positions in which the positive stamping mold with the negative stamping mold on the upper or lower tool does not coincide. This resulted in damage to the embossing tools during one cycle.
  • the tool must be designed so that even unembossed lid can be made.
  • a tool that can only be used for embossed lids represents a considerably high cost burden for such a process.
  • the tool would be provided so that it can be converted by a few simple steps to a standard tool without dies.
  • the invention also encompasses a lacquered, printed and embossed deep-drawn, in plan view, circular cover made of aluminum, substantially in the form of a cylinder open on one side, in which the printing on the essentially flat surface has at least one contour which also defines the contour the pre- represented by a sequence of the steps referred to in the previous sentence.
  • the inventive method it is possible to integrate the embossing process in the cut-train-roll process in a one-step process.
  • the embossing force is sufficient to impress clean edges. It is easy to bring the embossing with the pre-painted lettering to cover, because the metal sheet is passed only once by a two-axis servo system under the embossing tool. Due to the special design of the ejector, it is possible to produce this can lid frog-free.
  • the embossing dies embedded in the tools can be easily replaced by non-contoured dies. This makes it possible to produce unembossed lid on the same tool.
  • the dimensional deviation between the contour of the coating and the contour of the embossing is not more than 0.3 mm.
  • the tool consists of an upper and a lower tool which are driven by a crankshaft and the lower tool has at least one core (1), a fold holder (2) with integrated rolling ring (2a) and a cutting ring (3) in that the upper tool has a punch (4) and an ejector (5) and the ejector has an embossing tool in the region of its center, ventilation and fixing holes outside the embossing tool and an annular clamping area (6) near the edge, the edges of which are at least 8 mm apart and which is free of drilling and mounting holes, wherein the upper tool is not freely rotatable and on the lower tool also has an embossing tool, wherein the embossing tools are aligned with each other and in the ejector and core (1) are let.
  • the process steps (b) trimming the aluminum panel 135 to 145 ° after TDC, (c) thermoforming 140 to 170 ° after TDC, (d) embossing 170 to 180 ° after TDC, (e) possibly Randrollung 180 to 200 ° after TDC and (f) if necessary blow out 330 to 360 ° after TDC, in each case based on the position of the driving crankshaft.
  • the embossing tool is provided on the core (1) with two mounting holes and two ventilation / Abd Wegbohrept. It is very particularly preferred if the tool has clearances between the lower and upper tool and between the punch (4) and the fold holder (2) and core (1) of 20 to 40 ⁇ m.
  • the tool has an ejector, which is opposite to the later lid shape towards the open side of the lid towards at least 50% of its surface by 0.4 to 0.9 mm arranged opposite. It is particularly advantageous when manufacturing on a tool with Throughputs of at least 150, more preferably at least 190 pieces / min is performed. It is also of great advantage if the lid consists of an AlMg alloy with 2.5% Mg.
  • the invention also includes a can containing a cosmetic preparation in which the lid has been prepared as described above.
