Description

GERMAN

The invention relates to a method of assembly from accumulators, in which glass wool is placed between and around the plates.

It is essential when assembling the accumulators that as much glass wool as possible between and around the plates is brought and that this charged outside of the accumulator vessel with glass wool Plate set can be inserted into the battery container without difficulty.

According to the invention, the procedure is now as follows: that such a large amount of glass wool united between the individual plates to form a block Plate sets is brought so that they spread apart at their lower ends, whereupon under pressure this spreading is eliminated and the plates are brought into a parallel position to one another and if so this state is reached, on the end faces of the plates cover caps made of insulating plastic be put on, which encompass the two outer plates laterally and are held so strong that they withstand the spreading pressure of the inserted glass wool, so that now the introduction of the glass wool equipped plate block can be done in the accumulator vessel.

The plate sets inserted in the accumulator vessel are therefore tightly enclosed on all sides by the insulating, acidic glass wool packing, and it therefore, the acid will spread over the entire area of the plates brought to this so that the full utilization of the capacity of the plate sets is given.

According to a further embodiment of the invention, one can proceed so that initially the entire Plate block on its upper and lower long sides and the broad sides with a perforated cover piece under compression of the glass wool placed between and around the plates is provided and then the cover caps are placed on the end faces of this block and then the plate block is inserted into the interior of the accumulator vessel.

In this way, after the cover plates have been placed on the end faces of the blocks, a Secure holding together of the plate sets, which are abundantly loaded with glass wool. You are ready compressed so that they can easily be inserted into the accumulator vessel bring in · let.

You can also use a suitably cut cover piece over the two broad sides and the upper one Place the long side of the plate set and another cover piece over the lower long side and the both ends of the plate block. Thereupon both pieces with the overarching ones provided for them The tabs are attached to the adjacent cover surfaces by gluing or the like.

In this way, the entire set of plates is on all sides from the outside and also inside between the individual Plates abundantly loaded with glass wool, which, however, are pressed together on the outside by the cover pieces and is covered so that the plate set can be easily inserted into the accumulator vessel leaves.

The invention is described and illustrated by way of example with reference to the drawings.

The plate block of the accumulator consists in the usual way of several lead plates 1 and acidic Glass wool layers 2. The loose glass wool packing 2 must be so strong that the stack of plates is initially thicker than the clear cross-section of the cell vessel 3 (Fig. 1). As a result, at the assembly of the stack are compressed so far that they can be pushed into the vessel 3 can. This compression of the stack of plates

So far it has been difficult to use the free hand, which is associated with the disadvantages outlined above.

According to the invention, the prepared plate block 4 (Fig. 2) is provided with cover caps 5, 6 on at least two opposite sides. The caps 5, 6 have protruding edges 7j with which they overlap the flanks of the plate block 4 and keep the latter pressed together to form a compact unit. The width of the cover caps 5, 6 is adapted to the clear width of the vessel 3, so that the insertion of the plate block no longer presents any difficulties.

In the embodiment of Fig. 5, the two caps 5, 6 are on the broad sides of the Plate block 4 is provided. You are through * 5 an intermediate piece 8 covering the stack 4 at the top connected to one another, while their lower edges 9, 10 are bent around the bottom of the plate stack 4. There are two holes in the ceiling piece 8 provided for the passage of the electrodes 11.

In the embodiments according to Fig. 6 and 7, the plate block is covered on all sides. this happens by two cover strips 12 and 13, which are offset from one another at right angles around the stack of plates are placed that the strip 12 the narrow sides of the block, the strip 13 the broad sides enveloped. The cover strip 12 overlaps the cover of the plate block with two bent, possibly glued edge flap 14. To secure, a cap-like Body can be placed with protrusions on all four sides.

In the embodiment according to Fig. 8, the cover consists of a center piece on which the Floor surface of the plate block comes to stand. On the middle piece 16 are four tabs 17, 17 'and 18, 18' arranged, which can be folded up and the plate block 4 on the four flanks cover. The width of the strips 17,17 'corresponds to the broad sides of the plate block, while the Width of the strips 18, 18 'is adapted to the narrow sides of the block. The strips 18,18 'are with protruding edges 19 provided, which overlap the wall strips 17,17 'laterally and by gluing or otherwise secured '.

Fig. 9 shows a cover which consists of a single strip 20, the ends 21, 21 ' overlap each other. According to Fig. 10, there is the one surrounding the flanks of the plate block as in Fig. 9 Cover strips made of two parts 23, 24, the inner edges of which overlap. Securing this the plate block on the broad and front sides enveloping strip 20 can through at the bottom and on cover caps 22, indicated by dash-dotted lines, placed on the ceiling.

The cover film, which is made of relatively stiff acid-resistant plastic, is in all cases Provided with numerous openings 25 to enable gas to be discharged from the plate block. There are also advantageous ribs or. Like. Elevations attached that these walls of keep a sufficient distance from those of the vessels. For the same purpose, the stack of plates rests on the provided with incisions, so comb-like baseboards 26 (Fig. 11), which are glued to the base cover are.
