When bulbs for incandescent lamps or discharge tubes after washing in large numbers and Need to be dried quickly, prepares the elimination of the residue left on the objects Amount of moisture significant difficulties. Leaves it by dripping or by supplying heat Although most of the moisture will be removed, the flasks will not succeed this way to make them completely free of moisture after a short drying treatment. It is a rapid one Removal of the last remnants of moisture that collects as an extremely thin skin on practically the entire lower circumference of the piston, e.g. B. thereby achievable that this moisture is completely evaporated. The disadvantage, however, is that this requires a relatively large amount of energy and costs.

The particular difficulty of the complete and yet rapid drying of such cobs lies in that the entire piston surface inside and outside thin-skinned covering moisture are caused must to contract to droplets, at a point where they are caused by hot gas streams or can be blown off in any other way. Without taking this requirement into account with the known means of blowing off water droplets accumulating on the edges of the good or the Exposing the outer surface of the bottles to be dried to the blown air, no complete drying out of the inner surfaces of the flasks reach.

Using a horizontal support that can be moved through a drying zone for downwards directed flask neck by hot gas streams to be dried incandescent lamp bulbs and similar hollow bodies However, this aim can be achieved if bearing pins fastened to the carrier according to the invention for the flask head, a bracket that tilts the flask after the drying zone and vertically directed towards the deepest neck edge part of the tilted piston, e.g. B. liquid wipers designed as air nozzles are provided.

The invention is described below with reference to the drawing showing an exemplary embodiment explained in more detail.

F i g. 1 is a schematic plan view of part of an apparatus for drying damps Light bulb;

F i g. 2 and 3 are partially sectioned views as seen in the direction of arrow II and seen, respectively along the line III-III in FIG. 1.

In the device shown for drying moist incandescent lamp bulbs, a turntable 2 is a movable support for the items to be dried
Incandescent lamp bulbs and similar hollow bodies

moved stepwise in relation to a table 1 in the direction of arrow 3. On the circumference of the turntable 2 a plurality of holders 4 are attached, in each of which an incandescent lamp bulb 5 with downward pointing Flask neck can be held. For this purpose, each holder is two on one on the turntable 2 fastened bearings 8 welded arms 6 and 7 are provided, which are connected to one another by a cross strut 9 are connected. The arms carry four bearing pins 10, which are arranged in an inclined position Pointed support points for a glass bulb 5 to be dried are.

A wire guide 16 attached to the table 1 is arranged so that, after the drying zone, the downwardly directed flask neck 17 of a flask 5, during transport in the direction of arrow 3, abuts against a bracket 18 of the wire guide 16 directed inwards towards the center of the turntable and thus out of its vertical hanging position is tilted sideways to the in F i g. 3 position shown. The moisture that would otherwise run off over the entire circumference of the neck edge part is drawn together after the tilting movement to form a drop that forms on the deepest neck edge part. In order to prevent the piston neck 17 from remaining behind the spherical part of the piston during the tilting movement described, the arm of each holder 4 is provided with a bracket 20 made of wire

provided, on which the tilted piston neck 17 can be supported with point contact.

Of the device according to FIG. 1, only a few workplaces 30 to 34 are shown. To the the Job 30 preceding positions, for example, the pistons are subjected to a flushing process. In the job 31, the wet flasks still have a temperature of z. B. 50 ° C.

In the workplaces 30 and 31, where the cleaned and moist flasks are directed exactly downwards with the open end, a gas stream with a temperature of about 120 ^° C. is blown centrally into the flask 5. As a result, this flask is dried on practically the entire, spherical part.

In the workplaces 32 and 33, the piston is treated in the same way. In these places however, the piston assumes an inclined position. As a result of this situation, the after treatment Moisture layer 35 (FIG. 2) left at the point 31 on the neck part 17. Opportunity to to collect such that at the lowest point of the inclined piston 5, a drop of liquid 36 forms (Fig. 3).

The drop 36 formed can now be eliminated in that the lowermost part of the piston 5 is brought into contact at point 34 with an absorbent wiper arranged there or, which has even better success that by means of a fixed blow nozzle 40 against the deepest part of the neck edge of the tilted piston a hot gas stream 41 is blown which, viewed in the height direction, has a very small dimension.

This hot gas flow tears the liquid droplets formed, probably as a result of the gas flow ejector effect generated at points 37 and 38, from the piston surface.

In the illustrated embodiment, this is explained using the work stations 30 to 34. Dependent on Of course, the number of jobs can depend on the shape of the piston or hollow body to be dried can be expanded as required.

Claims (1)

Claim: Horizontal support that can be moved through a drying zone for the flask neck pointing downwards Incandescent lamp bulbs and similar hollow bodies to be dried by hot gas streams, characterized by on the carrier fixed bearing pins for the piston head, one tilting the piston after the drying zone Brackets and by pointing perpendicularly to the deepest neck edge part of the tilted piston, e.g. liquid wipers designed as a blow nozzle.
