The invention is directed to a device for the immersion treatment of workpieces in aggressive Liquids, especially for acid polishing glassware, with arranged in a row next to one another, the liquid-containing troughs in which a container for the workpieces is immersed and is moved therein, the one along the swing arm which can be raised and lowered by a servomotor Troughs movable lifting and lowering device is suspended.

The workpieces to be treated in these baths are generally stacked in baskets or in Given drums and immersed in these containers in the respective bath. The successive Troughs contain various liquids, e.g. B. when acid polishing lead-containing glassware first actual polishing tape made of a mixture of different acids, then one or more rinsing baths, e.g. B. with Sulfuric acid, and finally a rinsing bath, e.g. B. with water. One and the same container passes through one after the other all different bathrooms. In the case of the previously known devices, this is the case in each case posted a conveyor and after dipping into the respective trough, separated from it again. Will Related to baskets, each basket has its own hanger, which not only increases the outlay on equipment, but is also responsible for the fact that such baskets cannot be stacked. Of special The importance of these devices is that the drive parts to largely within the action of the different liquids and their vapors. resulting in considerable constructional difficulties leads and particularly complex precautions ο rowing.

It belongs to the state of the art, an apparatus for the acid polishing of glass objects of the above mentioned Art (DT-AS 14 96 479) with a lifting and lowering device that can be swiveled over the individual troughs for the containers, which on one of the troughs

the invention provides that on the fork a disengageable drive transmission to one in the bracket of the fork mounted drum is arranged. These measures are based on the idea that when using a drum, the eccentric movement the carrying fork is dispensable, since here the drum rotation for sufficient loosening and correspondingly intensive flushing of the workpieces 50 ensures. On the other hand, however, the device should be without major Retrofitting without further ado with two possible containers for receiving the workpieces can be operated.

It is within the scope of this idea to arrange a chain-belt drive or the like between the drive arranged on the carriage and the shaft and between the drive wheel that is mounted on the shaft and the shaft and between this drive wheel and another drive wheel that is arranged on the fork Drive overhang to the drum a coupling is to be provided, which alternate in b / w. disengage. When using a "basket container as will hereinafter ■:;. I s coupled corresponding neiirad with the shaft - ■ Mi '.

According to the invention, this drive transmission has an output gear with a toothed ring the drum is engaged. A changeover clutch is advantageous for this arrangement.

According to another feature of the invention, a in the range of motion of the in lift position is on the carriage located basket protruding stop arm arranged. This will make the excavated The basket is tilted and the liquid wedge drains off.

It is within the scope of the invention that between the hanger and the fork and / or between the hanger and a releasable lock is disposed on the basket. This ensures that in the two in A reliable connection can be established in the relevant cases. When immersing the with the hanger locked basket in the treatment liquid acts a considerable buoyancy when you the high specific weight of such liquids, such as. B. sulfuric acid, taken into account. On the other hand should Of course, a connection that is as firm as possible can also be established between the basket and the hanger does not affect the pivoting movement of the basket.

The hanger preferably used in the device according to the invention consists of two by one Support shaft interconnected side cheeks, on which the locking device opposite the fork and / or the locking device are mounted opposite the basket. This thought can be constructive develop in such a way that on the side walls of the hanger each one in their distance to the side cheek adjustable clamping plate is arranged, which in the closed position a support edge of the Knrbes reaches under. If the clamping plate is loosened the hanger is placed on the basket. Then the clamping plates are adjusted so that they grip the basket firmly and if necessary press it against the side wall. To adjust the clamping plate, you can use for example, an eccentric with a corresponding handle or a screw hole with a coarse thread Find use. According to another feature of the invention is for this purpose at one of the two mutually adjustable parts, d. H. Side cheek and clamping plate, mounted on a high helix nut and on the other part a threaded bolt engaging in this is arranged when the Nut is the threaded bolt pulled into the nut or unscrewed from her so that the desired adjustment movement results.

The locking device between the hanger and fork may be designed in this way in detail be that on both cheeks (in Fig. 3 only shown on one side) of the hanger a lockable slide is arranged, which engages under the bracket of the fork in its locked position, so that the buoyancy generating forces can be counteracted. The one receiving the hanger can go up Bracket of the fork must be open. If the device works with a drum, this point of view plays a role therefore does not matter, because such a drum usually only has a part of its diameter immersed in the liquid bath and a larger part is above the liquid level

The device has a number of troughs 1 arranged side by side and resting on a base 2. This is provided with an extension 4 on the front 3 of the troughs 1. In this extension 4, an upwardly open U-shaped rail 5 of a roadway is mounted, which is located on the front side 3 of the adjacent troughs 1 extends along and at one or both ends of the row around a corresponding one Piece is continued. An upper rail 7 of the roadway is mounted on step 6. On this a carriage 8 is movable. It has rollers 9 on its foot, which guide in the lower rail 5 Find. Further rollers 10 run on the upper rail 7 of the roadway. The from Fig. 2 apparent width of the carriage 8 corresponds approximately to the width of a trough t. In the carriage 8 is a drive motor 11, for. B. a hydraulic motor, mounted, which drives at least one of the rollers 10 via a chain drive 12.

In the two side parts 13 of the carriage 8, a shaft 14 is mounted, at both ends of which each has an eccentric 15 is attached, each of a leg 16 of a trough 1 overlapping fork 17 for storage serves. The two legs 16 are supported by a strut 18 connected to one another, and they each have a bearing shell 20 at their free end 19. At the car 8 a pneumatic or hydraulic servomotor 21 is supported, the piston rod 22 of which is on the strut 18 engages and causes the fork 17 to be raised and lowered.

The carriage 8 also has a drive 23, possibly in turn a hydraulic motor. the drive shaft 24 of which carries a sprocket 25. This is drivingly connected to a further chain wheel 27 on the shaft 14 via such a chain 26. A coupling is provided between the chain wheel 27 and the shaft 14, namely the chain wheel 27 in the form shown in FIG. 2 position shown with the shaft 14 rotatably gekup pelt To disengage this sprocket 27 is moved in the direction of arrow 28. While it is thus uncoupled from the shaft 14, it comes into engagement connection with a loosely mounted on the shaft 14 further sprocket 29 on the leg 16 'de! Fork 17 arranged drive transmission. This has a chain wheel 31 connected to the chain wheel 2 <by the chain 30 and a toothed wheel 32 which is non-rotatably coupled to this and which meshes with a toothed ring 33 of a drum 34. The drum 3 has a perforated jacket 35 and axial shaft stubs 36. with which it is mounted in the bearing shells 2 of the fork 17 (see in particular Figs. 6 and 7], the coupling 37 is between the two Kcttenrä

Engaged with the 27 and 29 so that they rotate loosely on the shaft 14, the drive of the motor 23 acts Via the Celtic drive 26 and the further chain drive 30 on the drum 34 and sets this together with the in workpieces housed inside them in the-> walking movement.

In the case of the in FIG. 1 shown embodiment The fork 17 carries a basket 39 via a hanger 38 as a container for receiving the workpieces to be treated. This hanger 38 has a Tragwelie 58 and two side cheeks 40 and 40 attached to it at a distance 41, which at the lower end has a shoulder-like recess 42 for resting on the stacking edge 43 of the. Basket 39 have. On each cheek 41 of the hanger 38, a screw bolt 42 is attached to the On the outside of the cheek 41, an elongated hole 43 passes through a slide 44 and a fastening nut 45 wearing. This slide 44 is between the two positions 44 and 44 'in FIG. 5 movable. He knows! one the outer contour 59 of the bearing shell 20 of the fork 17 corresponding shoulder-like recess, which in the position shown in solid lines engages under the bearing shell 20 and a lifting of the with the two shaft ends 46 in the fork 17 resting hanger 38 prevented without the pivotability of the hanger 38 to affect the basket 39. (The slide 44 is shown in FIG. 3 for simplicity only shown on one side).

To lock the hanger 38 with respect to the basket 39, two clamping plates 47 are used, each of which is attached to the Outside of the two cheeks 40 and 41 are mounted. A threaded bolt 48 is attached to the clamping plate 47, whose steep thread engages in the corresponding mating thread of a nut 49, which is in the Seitenwar.ge 40 or 41 is mounted and provided with a pivot lever 50. An upper longitudinal nose 51 of the Clamping plate is intended to engage in a corresponding groove 52 of the respective side wall 40, 41, while a lower longitudinal nose 53 of the clamping plate 47 engages under the lower edge of the stacking edge 43 of the basket 39.

In Fig. 3 is the opening position of this on the right Clamping plate 47 reproduced. If the pivot lever 50 is pivoted by approximately a quarter turn the screw bolt 48 is drawn into the nut 49, and the clamping plate 47 arrives with both the Side cheek 40 or 4t, as well as engaging with the stacking edge 43 of the basket 39, which is shown on the left in FIG. 3 is reproduced.

If the workpieces to be treated are accommodated in a basket 39 instead of the drum 34, the carriage 8 takes the basket 39 outside the first or last trough 1 of the series, and the fork 17 is raised to such a height by the servomotor 21 this in dashed lines in FIG. 1 is indicated at 39 '. By lowering the fork 17 accordingly with the aid of the servomotor 21, the basket 39 is now immersed to below the liquid level 55. If now in the gear position according to FIG. 2, the drive motor 23 is put into operation, the fork 17 and thus the basket 39 via the hanger 38 receives an elliptical movement with the lateral component χ and the vertical component y (cf. FIG. 1).

As a result, the workpieces located in the basket 39 are removed from the liquid wedge located in the trough 1 intensively rinsed. After the treatment has ended, the basket 39 is moved by the fork 17 from the trough 1 via the Position 39 'is lifted into position 39 ". Thereby the basket 39 comes to rest against the one on the upper one Attached to the end of the carriage 8 and protruding into the movement path of the raised basket hit 56 so that it is tilted accordingly, wit this from FIG. 1 can be seen. In this way eir particularly fast and complete drainage of the treatment liquid to the treated workpiece achieved.

The trough 1 is surmounted by an extractor hood 57 which may lead to a fan of the suction pipe is connected. Trough 1 as well as hanger 38 and basket 39 as well as drum 34 exist made of a durable plastic.
