Definitions
- the advantages achieved with the invention are, in particular, that the sealing of the slots is carried out practically automatically by the pressure of the bath liquid.
- the rods or tubes in the treatment bath they are pressed on the one hand against one another or against a continuous workpiece and on the other hand against the end wall of the treatment cell, that is to say the rivers, from the inside by the pressure exerted on them by the bath liquid ⁇ liquid pressure causes a seal exactly at the points where the bath liquid could escape.
- a rotatable mounting of the rods or tubes and in particular a drive, as in the known roller pairs used as seals, can be omitted.
- the embodiment according to claim 2 enables the rods or tubes to rotate automatically as they pass through the workpieces and thus also to treat workpieces which are extremely sensitive to friction.
- the accommodation of the seals in lock chambers according to claim 3, allows a certain guidance and retention of the seals without affecting the loose arrangement required for the sealing effect in the bath liquid.
- the embodiment according to claim 4 enables the use of commercially available rods or tubes which, moreover, are not attacked by most treatment baths.
- the development according to claim 5 enables the seals to be automatically adapted to different heights of the workpieces passing through.
- the lower segments are pressed against one another by the liquid pressure, while the upper segments are pressed against the workpiece that is passing through.
- FIG. 1 shows a plan view of a treatment cell provided with lock chambers on the inlet side and outlet side
- FIG. 2 shows a cross section of the treatment cell shown in FIG. 1,
- FIG. 3 shows a lock chamber of the treatment cell shown in FIG. 1 in detail
- FIG. 4 shows a segmentation of the seals arranged in the lock chambers.
- FIGS. 1 and 2 show in plan view or in cross section a treatment cell BZ arranged in a collecting trough AW and containing a treatment bath BB, through which plate-shaped workpieces W hanging vertically on clamp-shaped transport means T are passed.
- a treatment cell BZ arranged in a collecting trough AW and containing a treatment bath BB, through which plate-shaped workpieces W hanging vertically on clamp-shaped transport means T are passed.
- lock chambers SK At the two ends of the treatment cell BZ there are lock chambers SK, in which seals D formed by circular cylindrical plastic tubes are in pairs and in different tical alignment are loosely arranged.
- the end walls of the treatment cell BZ, the lock chambers SK and the collecting trough AW are provided with vertical slots S through which the plate-shaped workpieces W can be passed unhindered.
- FIG. 4 shows that the seals D are divided into segments SG in the vertical direction. This enables the sealing to be automatically adapted to different heights of the workpieces W passing through.
- the lower segments SG are pressed against the workpiece W passing through and the lower segments SG against one another.
- the sealing of the treatment cells described above is particularly suitable for the treatment of printed circuit boards in galvanic baths and other treatment baths.
- the principle of sealing by means of bars or tubes which are loosely arranged in the treatment bath can also be used in the case of plate-shaped workpieces which have projections, ribs or other heights, provided that their height is only slight. Circumferential grooves in the seals or segments with a correspondingly reduced diameter are then assigned to these projecting parts.
