- the rams 18 act on the correspondingly positioned workpieces 5, whether directly or indirectly, for example via a receiving plate (not shown here), and their advance moves the workpieces 5 to the openings 3 or back from the latter to the required extent.
- each of the drives 16 can be activated whenever desired, and on the other hand its stroke can be specifically designed in such a way that the respective processing on the respective chamber 14 requires it. If the chamber 14 is, for example, a lock chamber, a somewhat larger stroke may be required on the corresponding drive 16 than on other chambers in order to achieve a seal in the opening area 3 which satisfies higher requirements.
- each of the provided plungers is provided with its own drive 16.
- workpieces are fed from the carousel to two chambers 14 each assigned to large circles K, in most cases chambers 14 being provided only along a large circle K with a corresponding design of carousel 11 and drives 16.
- FIG. 2 A preferred embodiment of such a drive 16 is shown schematically in FIG. 2. It must be emphasized that such a drive, i.e. Generally, such a fluid-controlled, in particular pneumatic or hydraulic, seal control can also be used in vacuum treatment systems of a different type than that shown in FIG. 1, namely wherever the aim is to supply a workpiece to the opening of a treatment chamber, thereby sealing the latter to the required extent.
- a fluid-controlled, in particular pneumatic or hydraulic, seal control can also be used in vacuum treatment systems of a different type than that shown in FIG. 1, namely wherever the aim is to supply a workpiece to the opening of a treatment chamber, thereby sealing the latter to the required extent.
- a pneumatic drive is preferred for vacuum reasons.
- a sealed bellows 20 is provided on a wall, preferably a stationary housing wall 7a, which defines a transport space 9a on one side or, if appropriate, on a likewise movable transport element (not shown), for example for operating a plurality of treatment chamber openings 3a, preferably with a stabilizing section 22 or one Intervention part, as shown in dashed lines at 23.
- the workpiece 5 By pressurizing the bellows volume and expanding it, the workpiece 5 is raised against the opening 3a by a transport arrangement 11a, such as from the carousel 11 of FIG. 1, and thus the process chamber of the treatment chamber 14 is sealed to the required extent by the transport chamber 9a.
- a transport arrangement 11a such as from the carousel 11 of FIG. 1
- the process chamber of the treatment chamber 14 is sealed to the required extent by the transport chamber 9a.
- the bellows which may be spring-loaded, is retrieved with the workpiece 5.
- a fluid in particular pneumatically or hydraulically actuated or controllable sealing arrangement is realized in the opening area 3a of the treatment chamber 14.
- FIG. 3 schematically shows a further embodiment variant of a hydraulically, in particular pneumatically or hydraulically, preferably pneumatically controlled sealing arrangement.
- An elastic hose 30 or an elastic bellows is arranged around the opening area 3b of a treatment chamber 14 and, as shown by p, is pressurized in a controlled manner.
- the hose 30 expands within the scope of its inherent elasticity and lies sealingly against the transport arrangement 11b for the workpiece 5 or, if this is permissible, directly against the workpiece 5 (not shown).
- the workpiece 5 does not have to be displaced with respect to the transport arrangement 11b in the direction of the opening 3b or away from it.
- the arrangement shown schematically in FIG. 4 can take the place of the bellows or hose 30, which is replaced by a metallic bellows 31, which is optionally coated with an elastomer.
- the metallic bellows 31, optionally coated on the outside with elastomer, is preferably subjected to an O-ring arrangement when it is pressurized, as is schematically represented by p. 32 pressed.
