Definitions
- the invention relates to a cooling station for disk-shaped substrates, in particular for substrates of optically readable data carriers such as CD, CD-R, DVD, CD single, DVD single and the like, according to the preamble of the independent claims 1 and 4.
- blanks are produced with an injection molding machine from plastic granules, usually polycarbonate, which are processed in further steps until a finished CD, CD-R, DVD, etc. At the end of the production line . is present. After leaving the injection molding machine, the blanks are still hot and must be cooled to room temperature before further processing. Typically, the temperature of the blanks when they are taken over from the injection molding machine and placed in the cooling station is around 100 ° C. When removed from the cooling station, the blank should have a process temperature of around 22 ° C.
- Known cooling stations in which the blanks are transported over a cooling section by means of cooling spindles, have three cooling spindles arranged symmetrically to one another, each with a thread and a specific thread groove width.
- a disadvantage of these known cooling stations is that when the production is changed, for example from CD to DVD or from CD to single CD, the existing cooling station must be converted or replaced with a cooling station suitable for the new article. This leads to undesirable downtimes in the production line.
- the invention is therefore based on the object of specifying a cooling station which is equally suitable for substrates of optically readable data carriers with different substrate dimensions, i.e. can be used without modification.
- the main advantage of the present invention is that the production of optically readable data carriers becomes more flexible.
- a first level of flexibility is achieved according to claims 1 to 3 in that, in contrast to the prior art, the cooling spindles have two (or more) Have threads with thread grooves of different widths; the standard widths are designed according to the standard thicknesses for CD 1.2mm and for DVD 0.6mm.
- a second level of flexibility is achieved according to claims 4 to 7 in that, in contrast to the prior art, at least 4 cooling spindles are provided, with three cooling spindles each forming a group of cooling spindles which is matched to a specific substrate diameter.
- a first group is provided for CD's and DVD's with the standard diameter of 80 mm (so-called CD single, DVD single) and a second group of cooling spindles for CD's and DVD's with the standard diameter of 120 mm.
- it is provided according to subclaims 8 and 9 to combine both levels of flexibility with one another, so that, as a result, with a single cooling station all standard sizes of blanks of optically readable data carriers that are currently to be processed, from the transfer to the injection molding machine to the removal for the purpose Further processing can be transported and cooled to process temperature: CD 120mm 0, 1, 2mm thickness; DVD 120mm 0, 0.6mm thickness; CD 80mm 0, 1.2mm thickness and DVD 80mm 0, 0.6mm thickness.
- the cooling spindles are arranged asymmetrically to one another (subclaims 3 and 10), which has the advantage that the blanks do not always come into contact with the same point on their outer edge when they roll on the cooling spindles, ie the blank lies with one revolution always on a different position in the spindles. This advantageously leads to a more uniform cooling of the blanks.
- FIG. 1 perspective view of a cooling station with four cooling spindles for two substrate diameters
- Fig. 2 cross section through one of the cooling spindles from Fig. 1.
- the cooling station 1 shown in FIG. 1 consists of four identical cooling spindles 2, 3, 4 and 5, which can be driven on one side via an electric motor 6 with pinion 7 and a toothed belt 8 (as well as toothed wheels on the cooling spindles which are not visible here).
- the cooling spindles are only stored on the opposite side.
- the cooling spindles 3, 4 and 5 form a first group of cooling spindles for the blanks with a diameter of 80 mm.
- the cooling spindles 2, 3, and 5 form a second group of cooling spindles for the blanks with a diameter of 120 mm.
- the cooling spindles are arranged asymmetrically to each other in each group.
- the axes of the cooling spindles 3, 4 and 5 do not exactly form the corners of an upside down Triangular, but deviate somewhat from it. This ensures that the blanks, in this case those with a diameter of 80mm, always rest on a different position in the spindles during one revolution.
- the cooling spindles 2, 3 and 5 are arranged asymmetrically to one another.
- FIG 2 shows one of the cooling spindles 2 to 5 of Figure 1 in cross section.
- This cooling spindle with trapezoidal thread according to the invention has two threads 9 and 10, which do not run symmetrically to each other, so that two differently wide thread grooves 1 1 and 12 are formed, the width of which is adjusted to the thickness of the blanks to be transported.
- the thread 9 with the narrow thread grooves 1 1 is used for the blanks with a thickness of 0.6 mm (CD blanks).
- the thread 10 with the wider thread grooves 12 is used for the blanks with a thickness of 1.2 mm (DVD blanks).
