Description

I. Field of application

The The invention relates to the production of batteries.

II. Technical background

For example, if powerful, large batteries are to be produced, for example, as a source of energy for electric propulsion in vehicles, these are basically two independent of the mode of action and chemistry of the batteries, but primarily lithium-ion batteries currently in focus Procedures available:
Since such batteries always consist of thin, superimposed layers, either by winding these layers individual cells can be formed with a cylindrical shape, which can then be combined by stacking the cells into larger, approximately rectangular blocks, or the desired rectangular blocks are stacked corresponding rectangular blank of the individual layer materials generated.

The invention relates to the former manufacturing method, which has advantages and disadvantages:
On the one hand, it is easier to isolate the individual layers of a cell from each other in the wound cylindrical layers and also to automate their production.

To the Others, it is disadvantageous that between the blocks assembled into larger blocks Free rooms remain between the individual cylindrical cells, the Increase volume per energy unit of the total battery.

On the other side can these open spaces between the individual cells very good for cooling the batteries by means of flow through a cooling medium be used because the strong depending on the stress occurring Heating the batteries, which shortens their life quickly or this even destroyed, one of the biggest problems these batteries or the composite of such batteries Battery units is.

To For this purpose, the cylindrical cells in half-shell-shaped shots inserted and over here also connected to each other to compact rectangular blocks.

The Problem is that the half-shell recordings an exact Have cross-sectional contour, the cylindrical cells due to their Manufacturing process, however, relatively strong roundness and dimensional deviations exhibit.

At the Fixing the cylindrical cells in or between the half-shell recordings However, on the one hand the electrical insulation and on the other hand the thermal conductivity between the cell and the half-shell receptacle, resulting in a good temperature conductive material, mostly aluminum and therefore in all Usually also electrically conductive is to be ensured, and in a reproducible at any time Measure.

There the coating of the cells with an electrical insulating layer and a Thermoleitschicht by applying a pasty, curing Potting compound on the cells happens, with the Thermoleitschicht at the same time the bonding against the half-shell shots represents, despite the deviations the cells ensured a defined thickness of these layers which must be reproducible at all times.

III. Presentation of the invention

a) Technical task

It is therefore the object according to the invention, a method and an apparatus for producing blocks from a variety of assembled cylindrical cells available to provide, in the reproducible always the correct layer thickness on the electrical insulation layer and / or Thermoleitschicht on the cells or between the cells and the cell receptacles is achieved despite being simple and inexpensive Manufacturing process.

b) solution the task

These The object is solved by the features of claims 1, 28 and 50. advantageous embodiments emerge from the dependent claims.

The reproducible, correct layer thickness between the cells and the Half-shell shots are obtained by applying the electrical insulation layer and the Thermoleitschicht either sequentially or as a single Layer applied to at least the lateral surface of the cells and then this brought into contact with the half-shell receptacles and by curing the Vergussmassen these layers are glued, with several Rows of half-shell shots and cells one behind the other a block the desired size becomes.

The problem is that the electrical insulation layer must have a minimum thickness to provide the necessary electrical insulation, wherein this layer must necessarily be completely continuous, in order to avoid electrically conductive flashover from the lateral surface of the cell to the likewise electrically half-shell receptacle unconditionally.

ever more the electrical insulation layer in thickness over the necessary minimum for the electrical Insulation goes all the more unfortunately, however, the heat conduction between the cylindrical cell and the half-shell recording, simultaneously acts as a heat sink, so that the thickness of the electrical insulation layer does not have a Maximum value may go out.

If for gluing a separate adhesive in the form of a Thermoleitschicht additionally is used for electrical insulation layer, here is the Requirement that, on the one hand, the bonding should be as complete as possible needs to be on one as possible huge area the heat transfer to enable. As with increasing thickness of the Thermoleitschicht the heat transfer is still reduced, should the Thermoleitschicht in the cured state one hand, if possible be thin, On the other hand, however, a total of at least a minimum layer thickness before Put together the cylindrical cells with the half-shell receptacles necessary, about inaccuracy the cells in terms of diameter and roundness over the exactly semicircular inner surfaces compensate for the half-shell recordings without it becoming a direct Contact between these two elements comes.

Furthermore have to of course cavities within the layers or between the surface of the cells and the coating or surface the half-shells and the coating must be avoided at all costs, because this impairs the mechanical strength on the one hand, on the other hand, the electrical insulation or thermal conductivity.

Around This will be done first on at least the lateral surface the cells the electrical insulation layer as a continuous gapless Layer applied with a defined layer thickness. The thermal conductive Potting compound is then separately - not necessarily from the beginning as a continuous layer, possibly also in Form of a glue bead - applied.

The Put together the thus coated cells with the half-shell recordings done preferably when the coating is already lightly gelled and a defined viscosity owns that the final one Layer thickness in the assembled state not by exclusively a predetermined force is achieved in the assembly, but by the cells and half-shell shots at a defined distance positioned and fixed to each other, which is sized that the existing not yet cured potting compound in between this distance completely and completely entire area fills and doing so by flow processes in the still not cured Potting compound the existing dimensional inaccuracies the cells and thus not at all points exactly the same distance between cells and half-shell recordings.

To that purpose also compensation rooms in the form of grooves or the like in the inner surfaces the half-shell shots for the potting compound be present.

Since the process should be automated as far as possible in order to produce high volumes at low cost, at most at the beginning of the process, the cells on the one hand and the half-shell receptacles on the other hand manually inserted into corresponding carriers, so that at least thereafter, the further process can be carried out automatically:
The cylindrical cells have at their end faces central projections, viewed in plan view have a non-round, usually polygonal, approximately square shape, but not exactly dimensionally correct and not exactly centric. In addition, each cell has at least one of its end faces at a circumferential location on the front side of a rotational position marking in order to position the cells in a desired exact rotational position can.

there The cells are preferably not in the automatically performed procedure individually but handled in devices containing several, for example six or eight, can take up cells.

First, be these cells z. B. manually inserted into an insert carrier, designed the U-shaped is prism-shaped on its floor near the side walls Recordings for the ends of the lateral surfaces the individual cells, which are in the inserted state with its longitudinal axis of one extending to the other side wall of the insert carrier, and thus located in the middle area at a distance to the bottom of the insert, leaving a claw with one claw under the cell with the other Claw from above the cell, can grab.

For the rotary position Loading are in the inner surfaces the side walls Recesses incorporated into the frontal central projections of the Cells fit exactly, but with a square lead, however in four different rotational positions.

Therefore must in addition to insert Care should be taken that the rotational position marking of the cell in the right position, for example at the highest point of the cell and thus z. B. above the Einlegeträgers, which is subsequently at the other Handling of cells equipped with cells insert carrier can be controlled automatically by means of a sensor, or already during loading of the depositor after inserting each individual cell.

This insert carrier will now move automatically along guides such as rails of spent the loading station to a clamping station, in the one Moving the cells automatically and individually by means of a gripper from the depositor in a tension-rotating carrier for one analog number of cells takes place. This conversion is necessary because in the tension-rotating carrier each Cell between two clamping heads in this tension-rotating carrier exactly centric positioned and recorded, which is not in the insert carrier the case was, as there is a resting of the lateral surface on the bearing surfaces still no Centric bearing causes due to the diameter inaccuracies and discontinuities of the cells.

The Centering between the chucks of the Spann rotary carrier takes place in that the individual cells from the Einlageträger means be taken from a gripper, the cells independent of their diameter always centered on gripper center, for example by always the two claws of the gripper when opening and closing moving synchronously away from or towards the gripper center and in the two gripper claws the identical, z. B. prismatic, self-centering Recording is formed.

There Thus, the cell with its longitudinal axis in Gripper always located exactly on the gripper center, the gripper can position the cell exactly centrically between the respective pair of clamping heads of the tensioning rotary carrier, since its position in the clamping station is exactly defined and known, and thus also the exact position of the individual pairs of clamping heads.

Of the Spann rotary carrier is like the insert carrier roughly U-shaped built so that from each pair of chucks one in each sidewall is arranged. Of these, the clamping heads of one side are rotating drivable and coupled with respect to the rotary drive, while the opposite chucks in the axial direction against a biasing force of the cell can be lifted are for inserting and removing the cells. In addition, the axially movable Clamps too all be opened together by means of an opening bar.

The chucks lie on the front surfaces of the Cells annular around the central polygonal projections around with an anti-slip material, in particular an O-ring, and the cells are sufficient in the tension-rotating carrier spaced apart from each other to the subsequent cleaning and to perform coating in this tension-rotating carrier.

At the Insert the cells in the loading station are the rotating drivable clamping heads all in the same, defined rotational position, and are in this rotational position also fixed.

To the insertion and tensioning of all cells in the tension-rotating carrier this drives in stocked condition automatically first to a cleaning station where the surface of the cells is cleaned, to the liability of subsequently to optimize the applied coating.

Preferably the cleaning is done by bombarding with atmospheric plasma carried out, by a plasma nozzle at a defined, small distance along the surface of the Cells is performed. Here is the tension-rotating carrier in the Cleaning station silent, and connected to a drive unit, the rotatably driven clamping heads and thus the clamped Cells synchronously rotate permanently while the plasma nozzle is moving along The generatrix of each cell slowly moves along and thereby overlapping each other spiral winding areas the entire lateral surface every cell is cleaned.

there is a movement of the plasma nozzle necessary in two spatial axes, namely longitudinal the cells for extending a cell and in the longitudinal direction of the tension-rotating carrier for Change from one to the next Cell as the carrier even stay in position because of the connection to the drive should.

alternative can also clean the surface be done by means of a laser beam whose energy is adjusted must be that the material of the lateral surface of the cells does not over the permissible level impaired but all the impurities will be burned away.

The Cleaning station also includes a suction, preferably in shape a suction snorkel near the plasma nozzle or the laser impact point on the surface the cells is positioned to those enriched with contaminants removed To suck in air.

Preferably, the temperature of the cell surfaces is also measured without contact during cleaning, since it is the cell len preferably by already charged battery cells, and thus the cells must not exceed a maximum temperature.

To The cleaning of the cells are the rotating drivable clamping heads of the clamping-rotating carrier in a defined rotational position stopped and fixed and then the Drive decoupled and in this state the tension-turn-carrier automatically proceeding to the first casting station, in which the electrical insulation layer first in the front and rear end of the lateral surface and in the adjacent edge region the faces is applied.

Also Here is the tension-rotating carrier stopped at a defined position, in which he also with a there existing drive unit for the rotationally driven chucks of the carrier is coupled to those in the carrier located cells during to drive the coating rotating.

The Namely, coating will be applied in the form of a spiral in tight turns on the lateral surface and also the adjacent face area applied fine bead of potting compound, their individual turns then still slight on the surface melt away and at the latest thereby merge into each other. Since the per unit of time brought out amount of potting compound as well is controlled as the rotational speed of the cells, is one defined volume of potting compound per surface unit of the cell applied, what kind of All described Vergussvorgänge applies.

Here Preferably, all cells received in the tension-rotating carrier are simultaneously coated side by side in one end area, facing each other the cells directed to a potting is. This is sloping to the surface the cell to coat both the lateral surface and the end face to be able to and the Vergussdüsen need it be movable in at least two spatial axes, namely in the longitudinal direction of the cells to the Take off the generatrix and in the radial direction of the cells, on the one hand the face area to be able to coat and on the other hand sensor-controlled on the lateral surface in real time the desired small distance of, for example, 0.5 mm between the potting and the lateral surface readjust and comply with the rotating cylindrical cell.

there have to the individual grouting nozzles at least in the radial direction for the wished small distance independently be controllable from each other while a coarse mobility in the longitudinal direction and radial direction also for all grouting nozzles together can be realized.

Around after coating one end region of the cells also the other to be able to coat become the potting nozzles placed at a distance from the tension-rotating carrier and the tension-rotating carrier by means of a below the tension-rotating carrier in this Vergussstation arranged hub rotation unit lifted up, rotated around the vertical axis by 180 ° and returned to its guides discontinued. Since now the drive side of the clamping turntable on the other side of the guides is there a second rotary drive exists there, with which the rotating drivable clamping heads now connected to the cells in the tension-rotating carrier he neut to turn permanently while by means of the grooving nozzles approached again, the other end areas the cells are coated.

These end-side electrical insulation layer should at least until grasping completely harden the cells in this end, which means in this case Time, ie curing time, he follows. Goes through for this purpose the corresponding tension-rotating carrier after coating the end regions of the cells and before the next processing station a buffer line whose passage time for the at least partial curing of end-side electrical insulation layer until the next processing step - in the the cells in this end area do not yet have to be seized - sufficient is. In the process, the cells in the tension-turn carriers become permanent further rotationally driven to influence gravity during the curing process to equalize as much as possible on the coating. This is along the buffer section a rotary drive available, the at all on the buffer section clamping-turn-carriers their clamping heads permanently drives.

Then he drives Clamping rotary carrier one Grouting station for the application of the central insulation layer, ie in the middle Area of longitudinal extension the lateral surfaces the cells, and takes there again a defined position along his guides one.

The Procedure and the structure of this Vergussstation correspond to the previous Vergussstation, with the difference that now the remaining middle area of the lateral surfaces of the cells coated and, consequently, the potting needles are also perpendicular to the outer surface of the cells can stand. Furthermore, no hub-rotating unit for the tension-rotating carrier is necessary because the middle Area of cells can be coated throughout in one operation.

Subsequently, the coated in the central region cells go with their clamping-rotating-carriers on a second buffer section, the length of which, however is dimensioned that the central electrical insulation layer does not harden, but only angeled, since the subsequent assembly with the half-shell recordings to finished blocks in the state of a defined viscosity of this central electrical insulation layer is to be performed and previously on the only gelled central electrical insulation layer, a thermally conductive potting compound, the mainly serves as an adhesive against the half-shell receptacles, must be applied.

Around Ensure that only cells are processed into blocks before mounting become a working one Have insulation layer is after the buffer line a station for testing the insulation layer available. For this purpose, six test shells, formed with a cross section in the form of circle segments of 90 ° to 120 °, the are slightly larger in radius as the maximum radius of a cell including insulation layer and 3 mm shorter on the face side are defined as the isolation layer on the cells, on a defined Distance to the lateral surfaces moved up the cells and connected to a pole of a high voltage tester. Of the second pole is at the end faces contacted the cells. By switching on the test voltage at simultaneous rotation of the cells about their longitudinal axis can cover the entire lateral surface the quality their electrical insulation are tested.

A another possibility is in the exam the insulation layer assist the cells. Here are always only individual parts of the resting cells checked. To The examination become the test shells moved away again, the cells rotated by 90 °, for example, the test shells put on again and the next Subarea tested, until the complete cell circumference was tested.

faulty Parts are sorted out.

To the Order of glue drives the tension-rotating carrier after the buffer lines to a Vergussstation for this Glue. The travel times between the individual processing stations or buffer line and processing stations are so short, that waived in this time on a rotary drive of the cells in the tension-rotating carriers can be.

The serving as an adhesive thermally conductive potting compound is preferably not immediately as complete Layer on the entire middle lateral surface, which later with the half-shell shots comes into contact, applied, but it becomes a defined volume to glue defined on the two with respect to the longitudinal axis halves of the central lateral surfaces the cells spread that under the action of the subsequent investment force half shell receptacles and cells against each other a full-surface distribution this adhesive takes place between the two components. To this Purpose can be used a job contour along each one half the lateral surface only one, z. B. in the longitudinal direction the lateral surface running, adhesive bead is.

Better however, there is an approximately bony order contour with widened ends at each longitudinal end of the central lateral surface area, to ensure that when subsequently contacting the half-shell receptacle also the furthest edge areas, ie the corners of the half-shell-shaped shots, be reached by the adhesive.

A such bone-shaped Order form can be achieved for example by a bundle of curved, longitudinal the cells on the lateral surface applied lines of adhesive, which narrower in the middle area is as in the outer area, or by a longitudinal direction running zigzag Adhesive bead having the same bony peripheral contour.

Around To achieve this, are in this Vergussstation the rotationally driven chucks in the clamping swivel carriage not permanently driven in the same direction rotating, but for example, oscillating back and forth about a certain oscillating Angular range, in coordination with the axial movement of the Vergussdüsen, the here either simply or again several times according to the number of the cells in the vehicle can be present.

Important is that the respect the longitudinal axis opposite halves the coated with the adhesive lateral surfaces in the correct rotational position and the adhesives of the two halves do not touch each other the glue does not over the joints between the later Half shell recordings should be present.

The correct rotational position is made possible by the fact that the rotary drive the cells in the tension-turn-straps at the beginning and end of each processing station to a defined Drehlage driven and fixed there.

The Kleberraupe is thus on the two halves of the lateral surface of the Cells in succession, so after rotation of the cells in the carrier about its longitudinal axis around 180 °, applied.

Simultaneously with the preparation of the cells, the preparation of the half-shell receptacles, which are generally made very dimensionally stable in the form of aluminum extruded profiles and thus in their cross-section, is also carried out:
Unlike the cells whose preprocessing took place in the horizontal state, the half-shell receptacles are prepared upright and standing for this purpose in half-shell supports positively received between holding post of the half-shell support, so that the semicircular, concave inner surfaces of the half-shell receptacles are accessible over its entire surface. This insertion is preferably done manually.

From there are the stocked out Half-shell carrier automatically turn along guides such as rails from Move berth to a cleaning station on which the half-shell support turn stops at a defined position and the inner surfaces of the Half-shell recordings in turn emitted by means of preferably a plasma nozzle and be cleaned.

To For this purpose, the plasma nozzle - possibly. as a unit together with the plasma treatment - in all three spatial directions be movable to successively the entire inner surface of a half-shell to be able to radiate and this one by one for all half shells.

There the plasma nozzle from one side of the guides for the Half-shell carrier usually oblique can reach, can in the half-shell carriers with two-sided Halbschalenaufnahmen only one side, so the one inside surfaces, to be cleaned.

Around also the other inner surfaces to be able to clean will after removing the plasma nozzle the half-shell carrier lifted by means of a lifting unit under it, rotated by 180 ° and again on the guides deposited in the same position, whereupon the other inner surfaces by the brought up plasma nozzle can be cleaned.

Also Here is a suction snorkel with impurities contaminated air or the plasma as possible sucked close to the cleaning object and is therefore also here preferably below the workpiece carrier.

The so prepared half-shell shots and cells can now be assembled to the desired blocks, for what first in one one-sided half-shell receptacle a series of cylindrical cells is inserted on this a double-sided half-shell receptacle is hung up on this the next Location of cells, etc., until completion by a final turn one-sided half-shell holder.

This process takes place in a production line for the blocks, with upright cells and half-shell receptacles and within a block carrier as an auxiliary device:
The block carrier is positioned on guides in a defined position in a joining station, through which the preparation lines for the cells on the one hand and the half-shell receptacles on the other hand run, and in this joining station, the clamping rotary carrier and the half-shell support each one in a defined position.

there Specially designed half-shell grabs grip one half-shell each in the half-shell carrier, remove them and move them to the block carrier, in the half shell receptacle defined by the gripper positioned is dropped and strained, and also grasps a cell gripper a cell in the tensioning rotary carrier, out of it after opening taken from the corresponding pair of clamping heads and moved to the block carrier and positioned there and clamped in the block carrier, possibly under Rotation of the cell if the cells have alternating longitudinal positions, So positive pole of the batteries above or below, positioned in the block carrier should be.

Of the block carrier consists of a base plate with side guides and a back Training for admission and leadership on the conveyor system, and clamping devices for each single cell to be inserted, the cell in its longitudinal direction clamp against the bottom of the block carrier can, and one of the two transverse tensioners for each half-shell receptacle, which can clamp each half shell individually in the transverse direction.

First, will a first one-sided half-shell receptacle upright with her outside created at the rear end stop of the block carrier.

Then transported the cell gripper one after the other as many cells zoom in as this half-shell receptacle on semicircular inner surfaces and positions each cell more accurately by means of the gripper Position upright at the correct distance to the half-shell holder, where it is so fixed by the jig of the block carrier.

Of the Cell gripper has two pairs of claws, one of each in one of the already cured End areas of the lateral surface attacks. Therefore, in the lateral guides of the block carrier on the bottom side such a recess exists that protrudes beyond the cell casing Gripper in the longitudinal direction under this leadership in the block carrier retract, open and can drive out again.

After the first half-shell receptacle is loaded, the second, now bilateral, half-shell receptacle is moved up by means of the half-shell gripper, positioned in the block carrier and with Tels the two transverse tensioner stretched in the transverse direction and thereby positioned in the longitudinal direction of the block carrier, since the two-sided half-shell receptacles in their end faces a z. B. prism-shaped bulge and the transverse tensioner has a corresponding engaging projection.

On this way, the block is assembled one after the other and completed by a last one-sided half-shell recording.

Whose Position is fixed by transverse tensioner and folding up an end flap of the block carrier from a horizontal to an upright position, in which they are the outside the one-sided half-shell receptacle is applied, and thereby by means of defined Distance between the end stop and the folded-up end flap is a defined one Length of the block pretends.

There now all individual parts, ie each cell and each half-shell holder, in the block carrier is individually fixed in position, in such a situation that by a sufficient contact force of the cells against the half-shell recordings the glue order over the entire inner surface each half-shell receptacle was distributed and thus a surface bonding between half-shell shots and cells is given, the blocks cure in this state.

There especially the central electrical insulation layer when joining already is angeled, can after closing the end flap even the jigs and cross clamps for the cells and half-shell receptacles are released again before curing, because a significant shift then due to end stop and End flap and side guides not possible anymore is.

Especially even before curing The bonding is done on both sides of the joints between the two against each other directed half-shell shots a caterpillar of a thermally conductive, elastic and not completely curing Adhesive applied, with the help of later, after removing from the block makers on each block and on each side of a heat sink, usually a rib-shaped aluminum body on the longitudinal outer sides the block is glued to the half-shell receptacles to heat dissipation to improve.

1a shows the parts to be glued together:
On the one hand a cylindrical cell 1 with a lateral surface 1a and the two end faces 1b and 1c , wherein centrically on each of the two end faces, that is on the longitudinal direction 10 the cell 1 , in each case a square, frontal projection 20a , B, which serves as a contact pole for the cylindrical battery cell 1 serves. On at least one of the end faces is also off-center and thus next to the frontal projection 20a attached at one point of the circumference a rotational position marking.

Below are the two types of half-shell shots 2a , b:
The upper one-sided half-shell holder 2a be consists of two integrally connected, channel-shaped receptacles with two semicircular inner surfaces 13 whose radius is the lateral surface 1a the cells 1 including the insulating layer and the adhesive application is equal to or slightly larger, in the longitudinal direction 10 but shorter than the cells 1 are. The one-sided half-shell holder 2a has an approximately constant wall thickness and on the convex curved outer side in the middle region depending on a flattening.

The two-sided half-shell holder 2 B has in two directions facing away from each other two adjacent inner surfaces 13 on and corresponds to about two back-to-back one-sided half-shell shots 2a , but is a one-piece component. This results in the end faces of the two-sided half-shell receptacle 2a a groove-shaped, running in the longitudinal direction, approximately V-shaped recess 51 ,

3 shows the finished glued together block 3 , bounded on the left and right of each one-sided half-shell holder 2a and in between four two-sided half-shell shots 2 B , between each of which two cells 1 next to each other and thus in total 10 Cells are located, the front side of the half-shell shots 2a , b each protrude by the same amount.

The free ends of the inner surfaces 13 adjacent half-shell recordings 2a , b do not touch completely, but form one in the longitudinal direction of the cells in between 1 running joint 21 ,

2 shows the whole plant to get out of the in 1a Items displayed automatically - despite the dimensional inaccuracies of the cells 1 especially in terms of diameter and roundness - the in 1b represented blocks 3 by gluing, wherein the bond must be electrically insulating and thermally conductive with a defined layer thickness.

The plant includes on the one hand a preparation line 101 for the cells 1 and on the other hand a preparation line 102 for the half-shell carriers 2a , b, at the joining station 103 for the blocks 3 merged and are each designed as a ring line to the empty carrier for the cells or half-shell recordings back to the starting point of the respective preparation line 101 . 102 . 103 to be able to lead back.

The lapping line 101 for the cells 1 This is much longer, because they have more workstations than the preparation line 102 for the half-shell carriers 2a , b.

Downstream of the joining station 103 is the casting station for the external adhesive 104 and the continuation to downstream processing stations.

The following is the preparation of the cells 1 for joining the blocks 3 along the preparation line 101 explains:
At an insertion station 101.1 in a defined position along the off of two parallel rail conveyors 25a , b exists (see 2 and 3a ) the in 3b illustrated Einlegeträger 4 manually complete with cells 1 stocked:
The insert carrier 4 is designed approximately U-shaped in its main extension direction, with a bottom 4a and extending in its direction of extension, on both sides of the ground 4a towering side walls 4b , c.

The cells 1 be transverse to the direction of extension of Einereineträgers 4 inserted and lie on opposite the top of the soil 4a increased circulation 24 on, located on the side walls 4b , c and integrally formed with these. This is in the side walls 4b , c a shoulder formed in the running direction of the insert carrier 4 depressions for receiving one end region of a cell in succession 1 is trained.

The free space between the side walls 4b , c is enough that the cells 1 in the longitudinal direction of end face to end face, but without their front projections 20a , b find space in between. For the projections 20a , b are in the inner surfaces of the sidewalls 4b , c recesses open at the top 26 introduced, whose width and depth slightly larger than the dimensions of the projections 20a , b, so that are in the carrier 4 inlaid cells 1 then only slightly turn or move in the direction of the wearer.

The cells 1 are slightly spaced in the insert carrier 4 standing at the bottom of his bottom 4a for guidance and transport by the rail conveyors 25a , b is configured.

When inserting the cells 1 in the rack 4 the depositor has to keep in mind that the cells 1 with its rotary position marking 22 in the same rotational position, for example at the highest point, and on the same side of the insert carrier 4 , namely towards the depositor, are positioned.

As 2 shows are the stocked Einlegeträger 4 along an annularly closed, quadrangular first transport path from rail conveyors 25a , b from the loading station 101.1 to the clamping station 101.2 transported, the following be is written, and from there the empty Einlegeträger 4 back to the loading station 101.1 ,

Here are the Einlegeträger 4 preferably not rotated at the corners of the quadrangular, closed transport path, but passed from one to the other of the running at an angle to each other rail conveyor, so that the transport direction with respect to the Einlegeträger 4 each changes by 90 degrees.

In the same way, the annular peripheral second transport path, in addition to the clamping station 101.2 also all other workstations to prepare the cells 1 located, designed.

3e shows one of the tension-rotating carrier 5 on this second major transport line of the lay-in line 101 circulate, and into which the cells 1 from the inlay carriers 4 in the clamping station 101.2 have to be implemented.

The tension-rotating carrier 5 are also roughly U-shaped, so they are between their side walls 5b , c the cells 1 However, the fixation of the cells 1 here another:
Every cell 1 is between a pair of chucks 27a , b, one of which, drivable chuck 27a from the inner surface of a side wall 5c and the other, axially movable chuck 27b in alignment with the inner surface of the other side wall 5b projecting inward to one on each of the end faces 1b , c of a cell 1 to press with an annular contact surface, in the adhesion improvement an O-ring 28 over the face of the clamping head 27a , b protrudes.

This is the free distance between the end walls 5b , c greater than in the insert carrier 4 ,

The rotating drivable clamping heads 27a are on the outside of the sidewall 5c rotatably connected to each other so that by a common drive pinion 29 from all the same speed and in the same direction of rotation can be driven, which is preferably by arranging gears on each of the clamping heads 27a Intermediate pinion arranged between them for synchronizing the direction of rotation takes place.

The axially movable and also rotatable clamping heads 27b are by means of spring force inside the tension-rotating carrier 5 , ie in the direction of the cells to be inserted there 1 , pretensioned and can by retracting their rear, from the sidewall 5b rearwardly projecting, thickened gripping ends 30 be withdrawn to a strained cell 1 insert or remove.

All grasping 30 are over an opening bar 31 coupled together so that the retraction of the opening bar all gripping ends 30 a tension-rotating carrier 5 opens together.

Also with the tension-rotating carrier 5 is the bottom for guidance and entrainment by the rail conveyor 25a , b, on which they are to be moved, trained.

The centering of the cells 1 with its longitudinal axis 10 on the center axis of the clamping heads 27a , b is not positive fit and especially not by means of the front projections 20a , b of the cells 1 because these are not exactly positioned and dimensionally stable, but only by inserting the cells 1 each individually and with their longitudinal axis 10 exactly on the longitudinal axis 10 ' the clamping heads 27a , b, and in addition in the correct rotational position.

As in the rack 4 is also in the tension-rotating carrier 5 between the bottom of the cells 1 and the top of the floor 4a respectively. 5a enough free space to the cells 1 in these straps with a claw 32 remove or insert, as in the chuck the 3c shown:
In this clamping station 101.2 each one is at least partially with cells 1 equipped insert carrier 4 in the removal position 101.2 , positioned and on another rail conveyor 25a , b next to a tension-rotating carrier 5 in the assembly position.

A gripper 32 with two pairs of gripping jaws spaced in the longitudinal direction of the cells 33a , b moves with open gripping jaws to the position of the next cell 1 in the insert carrier 4 at the removal position, the cell grasps, lifts it upwards out of the recesses 26 out and moves via a three-axis system, the cell in the next free pickup position, ie between the next free pair of chucks 27a , b of the tensioning rotary carrier 5 in centered position, and places it with its one end face on the drivable, axially but not movable chuck 27a at.

Then, like all unfilled, axially movable clamping heads 27a , b retracted clamping head 27b solved by this couple and by the force of the spring against the other end face of the cell 1a pressed on, whereupon the gripper 32 opens, moves back and the next cell from the insert carrier 4 get.

The gripper 32 owns in each of the gripping claws 33a , b a prism-shaped recording and synchronous movement of the two gripping jaws 33a , b on opening and closing perpendicular to the middle ne 34 of the gripper 32 too, is also at different diameter of the cells 1 the longitudinal axis 10 always on the same position of the median plane 34 of the gripper 32 ,

For this purpose, the gripper 32 designed as a parallel gripper and the gripping jaws 33a , b move along the same level of guidance on the body 35 of the gripper.

Because the cells 1 in the insert carrier 4 are also in the correct rotational position, they are then in the tension-rotating carrier 5 not only exactly centered, but also in the correct rotational position, which is maintained by the fact that during insertion of the rotary drive, so the drive pinion 29 , the tension-pivot carrier 5 is also fixed in this defined rotational position, as well as during the subsequent transport of the assembled tension-rotating carrier 5 along the rail conveyor 25 on which the complete with cells 1 fitted tension-rotating carrier 5 next to the cleaning station 101.3 according to 4 the procedure is:
There is the tension-turning carrier 5 again in a defined position on the rail conveyor 25a , b stopped and in particular also fixed, in such a position in which the drive pinion 29 of the tension-turning carrier 5 with one at the cleaning station 101.3 existing engine 40 can be coupled to the in-tension rotary carrier 5 held cells 1 to drive in rotation, preferably at a constant speed.

The cleaning station 101.3 includes next to this position on the rail conveyors 25a , b above all a three-axle carriage system 36 , on which on a projecting arm a plasma nozzle 6a is mounted so that it is above the tension-rotating carrier 5 can be moved and along the upper generatrix of each of the cells 1 can travel at a defined distance at such a speed that thereby by means of the plasma nozzle 6a exiting atmospheric plasma the entire surface area of each of the cells 1 is cleaned successively. For this purpose, the Ver driving speed of the plasma nozzle is 6a longitudinal 10 the cells 1 in controlled relation to the rotational speed of the cells 1 ,

In order to optimize the cleaning effect of the plasma, there must be a precise, small distance between the exit opening of the plasma nozzle 6a and the surface of the cells to be cleaned 1 be respected, which is why the height of the plasma nozzle 6a over the cell 1 may be readjusted due to the measurement of a distance sensor, which also at the plasma nozzle 6a optional available.

After all cells 1 are cleaned, takes the rotary drive and thus the drive pinion 29 of the tension-turning carrier 5 again a defined rotational position and is locked in this, which may for example be functionally combined with the decoupling of the drive pinion 29 from the engine 40 in that only in this defined a rotational position decoupling and coupling is possible.

Subsequently, the tension-rotating carrier 5 with the purified cells 1 proceed to a first Vergussstation 101.4 at which an electrical insulation layer 9a on the respective outer edge area 1a1 the lateral surfaces and the adjacent end surface area of the cells 1 , the so-called end-side electrical insulation layer 9a , is applied.

Again, the tension-rotating carrier 5 at a defined position along the rail conveyor 25a b fixed by the arranged there under the rail conveyors hub-rotation unit ( 41 ) the tensioning rotary carrier ( 5 ) from the rail conveyors ( 25a , b) lifts up and thereby the tension-rotating carrier ( 5 ) in several, on the top of the clamping hub unit ( 41 ) arranged positioning pin engages. Due to the exact lifting height of the tension-rotating carrier ( 5 ) three-dimensionally precisely positioned for processing. The casting station 101.4 includes a Vergusseinheit 39 with a number of parallel potting nozzles 38 according to the number of cells 1 in the tension-rotating carrier 5 , in this case six pieces, one by one from a multiple dosing head 37 be supplied with defined amounts of potting compound, wherein the dosing 37 in turn is in communication with a reservoir for the potting compound.

The Vergusseinheit 39 is again on a three-axle carriage system 36 mounted and the grouting nozzles 38 in the distance of the cells 1 are mounted, starting with z. B. the inner region of the edge area to be cast 1a1 as he is best in 11c can be seen along the generatrix of this cell 1 up to its end face and then along this face radially a certain distance inwards, wherein at a defined speed and thus volume unit per time casting compound emerges, which is adjusted to the rotational speed of the cells 1 , which also at this station by a motor arranged there 40 over the drive pinion 29 in the tension-rotating carrier 5 be driven rotating.

The vote is such that in this way spiral, z. B. on the lateral surface 1a1 applied adhesive bead touching each other with their turns at least after an initial slight lateral flow and give a consistently same thick coating.

For this purpose, beyond the distance of the Vergussdüsen must 38 from the surface of the cells to be coated 1 in each case individually and in real time be readjusted to the desired nominal distance due to the out-of-roundness of the cells 1 , again by distance sensors 42 close to the outlet openings of the potting nozzles 38 the actual distance is measured, which is also part of the Vergusseinheit 39 are.

Since this is about tenths of a millimeter apart, the position of the outlet opening of each casting nozzle must also be correct 38 relative to the Vergusseinheit 39 be known defined. Because the potting nozzles 38 itself also subject to skill inaccuracies, includes the Vergusseinheit 39 - Optionally depending but Vergusseinheiten - also a surveying station, not shown, to which they by means of Dreiachssystems 36 away from the rail conveyor 25a , b can be moved and with their help, the relative position of each of the Vergussdüsen 38 to the rest of the Vergusseinheit 39 can be determined. This is at least after the insertion of a new casting nozzle 38 performed, but preferably also at intervals in between, ideally after each individual Vergussvorgang.

So that both the edge area 1a1 the lateral surface 1a as well as part of the face 1b from the grouting nozzles 38 can be achieved well, are the Vergussdüsen 38 not perpendicular to the main plane of the tension-pivot carrier 5 but obliquely thereto, placing it with its rear end in the direction of the face to be coated 1b tilted at the Vergusseinheit 39 are mounted.

Having in this way the one edge area of the cells 1 is coated, moves the Vergusseinheit 39 at a distance to the tension-rotating carrier 5 and this is done by means of a below the tension-pivot carrier 5 in its stop position mounted lift-turn unit 41 from the rail conveyors 25a , b lifted off to the vertical center axis rotated 180 degrees and in the same position back on the rail conveyors 25a , B discontinued, hence the Vergusseinheit 39 with the slanted potted nozzles 38 now the other border area 1a1 the cells 1 reach and coat analogously.

For this purpose, since now the drive pinion 29 of the tension-turning carrier 5 located on the opposite side, there is another engine 40 for the rotary drive of the cells 1 arranged during the coating.

The applied end-side electrical insulation layers 9a should before taking the cells 1 completely harden in this area.

For this purpose, the tension-rotating carrier 5 with the edge-coated cells in a buffer section 101.5a according to 6 whose throughput time is such that they are sufficient for the curing of the marginal electrical insulation layer 9a during the turnaround time and the subsequent processing time in tales of the mid-range is sufficient.

While the tension-rotating beams 5 along this buffer line 101.5a , the cells become 1 permanently by means of a motor 40 in the clamping rotors 5 driven.

For this purpose, there is the buffer path 101.5a from a first and a second jam section 43a , b, in the transverse direction of the main conveying direction of the rail conveyor 25a B, which run along the work stations, protrude, with the one jam section 43a leading away from it and the other jam section 43b - after a 180 ° corner drive - the tensioning rotary carrier 5 back to the rail conveyor 25a , b returns to the main conveying direction.

The rotary drive of the tension-turn carrier 5 and with it the cells 1 is only along the straight holdings 43a , b realized, preferably with the help of a there by a motor 40 driven, along-running toothed belt 44 that on all drive pinions 29 attacks, while cornering no drive of the cells 1 he follows.

As the tension-rotating carrier 5 at the buffer point 101.5a arrive with a time delay, the clamping rotors 5 within the buffer section only moved clocked to just enough space for the next incoming clamping rotors 5 on the first jam section 43a to create so that the clamping rotors 5 with very little or ideally no distance behind each other along the baffles 43a , b are moved, reflecting the length of the buffer stretch 101.5a reduced.

After passing through this first buffer line 101.5a becomes the chip-turning vehicle 5 another casting station 101.6 ( 7 ) for coating the central area 1a2 the lateral surface 1a with a so-called central electrical insulation layer 9b method.

This casting station 101.6 is essentially like the casting station 101.4 built with the difference that the six grouting nozzles 38 now vertically from above down against the cells 1 protrude, since no face areas must be coated more.

Furthermore, the coating of the central area 1a . 2 done in a single operation, so no hub-turning unit for the clamping swivel carrier 5 is needed and therefore only one engine 40 on one side of the rail conveyor 25a , b to drive the cells 1 in the clamping swivel carriage 5 is needed.

This central electrical insulation layer 9b should continue until further processing of the cells 1 do not harden, but only drip, so fishing up to a defined degree of viscosity.

Therefore, the clamping rotors 5 with the just coated middle lateral surface 1a2 then on to another buffer line 101.5b drove the analogous to the first buffer line 101.5a is designed, the lead time but tuned to this and is usually shorter than that of the first buffer line 101.5b ,

Immediately after passing through the second buffer line 101.5 b becomes the tension-turn carrier 5 to another Vergussstation 101.7 (please refer 8th ) and stopped there and positioned (by means of a stroke positioning unit ( 41 ' ), the tension-rotating carrier ( 5 ) only raises and positions, but does not rotate), in which a Vergussraupe 15 with a thermally conductive adhesive, as best turn in 11c to recognize, on the central area 1a2 the lateral surface 1a and thus on the existing, gelled, central electro-insulation layer 9b is applied.

As 1c shows, the glue bead can 15 have the shape of a zigzag line running along a surface line, such a bead of adhesive 15 on two with respect to the longitudinal direction 10 opposite sides of the lateral surface 1 must be applied in each defined rotational position.

However, preference is given to an application form of the adhesive bead 15 , in total - in the supervision of the adhesive bead 15 considered - has a bone shape, ie with thickened ends of the order form to the end regions of the central region 1a2 down, as in the 11d and 11e in the supervision of a separate cell 1 shown.

This can be achieved either according to 11d through a bundle of approximately in the longitudinal direction of the cell 1 extending, single or interconnected, curved adhesive beads 15 , which form a line bundle, which is narrower in the central region and wider in the end regions. Alternatively, the adhesive bead 15 also similar to a zigzag line 11c However, which has a greater width than the average amplitude at the end regions, as in 11e shown.

To realize such an order, is the Vergussstation 101.7 again analogous to the Vergussstation 101.6 formed with the difference that preferably the Vergusseinheit 39 only a single casting nozzle 38 and thus the individual cells 1 one after the other with the glue bead 15 be equipped, which is due to the much shorter length of this glue bead 15 sufficient against the spiral adhesive beads in the previous Vergussstationen to the cycle time of these other Vergussstationen 101.4 and 101.6 observed.

The motor 40 drives the cells in this case 1 in the tension-rotating carrier 5 not permanently rotating in the same direction, but he performs - by a given predetermined center position - an intermittent pivotal movement of the cells 1 around their longitudinal axes 10 by according to the desired shape of the adhesive bead 15 and thus in coordination with the movement of the casting nozzle 38 along the cell 1 ,

After doing this for all cells 1 performed on the top, the cells are 1 in the tension-rotating carrier 5 180 degrees around its longitudinal axis 10 turned and on the opposite side the same order of the adhesive beads 15 carried out.

Furthermore, in this adhesive application 15 on a height regulation of the outlet opening of the pouring nozzle 38 be dispensed over the surface to be coated, as this bead of adhesive lower accuracy requirements are made, however, the underlying electrical insulation must have been previously checked as faultless.

The thus prepared and coated cells 1 be with their tension-rotating carrier 5 usually proceed immediately or after a defined short pot-stop time in the joining station 103.1 according to 14 to be assembled there with the half-shell shots, which in turn, however, also before a preparation line 102 for the half-shell carriers 2 have to go through, but which is designed much shorter:
Also this preparation line 102 includes in the square ring-shaped circulating rail conveyor 25a , b, on which the half-shell beams 12 be moved, which is analogous to the clamping-turning-carriers 5 the half-shell shots 2a , b and carry at an insertion station 102.1 according to 2 manually in the half-shell carrier 12 be set:
As 9a and 9b show are the half-shell carrier 12 plate-shaped, from the top holding rods 45 which are so dimensioned and spaced that between them the two-sided as well as one-sided half-shell shots 2a , B can be inserted form-fitting and standing from above, with each half-shell support 12 the number of half-shell shots 2a who wears for the creation of a block 3 is needed.

The half-shell shots 2a , b are along the transport direction of the half-shell carrier 12 especially in the joining station 103.1 for the blocks 3 lined on the longitudinal outer sides, but also in the middle so that the trough-shaped concave inner surfaces 13 each outward facing and are freely accessible, in the two-sided Halbschalenaufnahmen 2 B the opposing inner surfaces 13 but also to the middle of the half-shell carrier 12 clues.

The underside of the plate-shaped half-shell support 12 is in turn for guidance and entrainment by the rail conveyors 25a , b trained.

From the loading station 102.1 is the so-equipped half-shell carrier 12 to a cleaning station 102.2 (according to 10 ) and stopped there and positioned.

The cleaning station 102.2 for the half-shell shots 2a , b roughly corresponds to the cleaning station 101.3 for the cells 1 of the 4 except for a few differences:
The plasma nozzle 6b here is not vertical from above on the object to be cleaned, here the inner surfaces 13 the half-shell shots 2a , b, directed, but obliquely from the side, as the inner surfaces 13 stand vertically.

Preferably In this case, a rotating plasma nozzle is used, in which the discharged plasma jet set at a defined angle to the axis of rotation of the nozzle is and revolves around this. This can be done in a work process a larger area edit and a cheaper one Application angle of the plasma jet to the surface of the object to be cleaned to reach.

Furthermore, during the processing, the half-shell shots 2a , b within the half-shell support 12 not driven in rotation, so no related engine 40 needed for the drive.

However, there is also the hub-turn unit 41 to the half-shell carrier 12 after cleaning the one-sided inner surfaces 13 lift and rotate 180 degrees around the vertical axis, then the other inner surfaces 13 in the direction of the plasma nozzle 6b are directed and can be radiated by this.

If all the interior surfaces 13 all half-shell shots 2a , b on the half-shell support 12 are cleaned, the half-shell carrier 12 proceed to the joint line 103 (please refer 2 ) for the blocks 3 whose first processing station is the joining station 103.1 ( 14 ) is in which the rail conveyors 25a , b both for the tension-rotating carrier 5 with the cells 1 as well as the half-shell carrier 12 with the half-shell shots 2a , b as well as for the block carrier 16 for transporting the finished blocks 3 converge.

The items will be in a block carrier 16 put together, as in 12a is shown in the empty state and in 12b with a complete block inside 3 from cells 1 and half-shell shots 2a , b:
The block carrier 16 is plate-shaped and in turn on its underside for transporting and positioning on the rail conveyors 25a , b designed.

The block is on top of the block carrier 16 constructed, for this purpose in its longitudinal direction on the outer sides extending, leis tenförmige lateral guides 17a , B, whose free distance is just sufficient to the upright intermediate Halbschalenaufnahmen 2a b to record that their inner surfaces 13 into which the cells 1 are inserted, respectively in the longitudinal direction of the block carrier 13 point.

At the far end is the block carrier 16 closed by a cross bar and a towering end stop 14 , which is up to the height of the half shell receptacles placed in the block carrier 2a , b extends.

The top of the block carrier 16 is grooved in the longitudinal direction and designed so that the cells 1 , which have a greater length than the half-shell shots 2a , b, by half the difference in length between the two components deeper in the block carrier 16 stand, so later the half-shell shots 2a , b centrally in the middle area 1a2 the lateral surface 1a the cells 1 positioned slightly longer than the half-shell shots 2a , b.

The end stop 14 has a central, vertical standing bulge 14a on, which at one with the outside there created first one-sided half-shell receptacle 2a in a local back recess of the half-shell receptacle 2a is positioned and centered.

Then, step by step, there are always two cells 1 inserted into the last half-shell holder, then the next, then two-sided, half-shell holder 2 B created and so on, as in the 13 presented in detail and explained until the block 3 is completely created and by folding up the end stop 14 then opposite, frontal end flap 18 against the last scheduled one-sided half-shell holder 2a is present, in the block carrier 16 is secured and the block 3 can be further processed.

The insertion of half-shell shots 2a , b as well as the cells 1 in the joining station 103.1 takes place automatically by means of specific for the cells 1 respectively.

the half-shell shots 2a , b trained gripper 32 ' respectively. 32 '' as in the 11c respectively. 11a can be seen.

The grippers 32 ' . 32 '' are each on a three-axle carriage system 36 built up ( 14 ), whose travels in the transverse direction to the rail conveyors 25a , b are so big that they are in one case cells 1 from the tension-turning carriers 5 and in the other case half-shell shots 2a , b from the half-shell carriers 12 and to the block carrier positioned therebetween 16 transport and position, as in 14 represented the joining station 103.1 shows where all three workpiece carriers 5 . 12 . 16 in turn, are in a well-defined position and are fixed and thus also the items to be taken or placed in it.

It shows 11a that the gripper 32 '' both types of half-shell shots 2a , b at the front upper end and grab up from the half-shell support 12 pull out and also vertically again in the block carrier 16 settle in a defined position.

11c shows the gripper 32 ' for the cells 1 in the middle area 1a2 their lateral surface 1a have a not yet cured, gelled coating.

Because of this, the two pairs of gripping jaws 33a , B spaced so far and the width of the gripping jaws dimensioned so narrow that they only within the already sufficiently hardened edge areas 1a1 the lateral surfaces 1a the cells 1 grab, from the tension-rotating carrier 5 remove individually - after each individual opening of the respective pair of clamping heads 27a , b, which also automatically in the joining station 103.1 happens and she after rotation of the gripper 32 ' around a horizontal axis 90 degrees upright in the block carrier 16 position.

Since this then at the bottom edge area 1a1 the gripper claws 33a , b radially over the cell 1 protrude, are in the strip-shaped lateral guides 17a , b of the block carrier 16 to the center and the insertion direction oppositely open spaces 46 incorporated, which are sufficiently large that after positioning the cell 1 in the block carrier 16 the gripping claws 33a , b also can open to the cell 1 let go and drive back.

The 13 now show the joining of the parts to blocks 3 , It should first be recognized that at the joining station 103.1 further auxiliary devices are present, namely in each case a vertically acting clamping device 47 from the top of the face 1b every cell 1 presses and two transverse clamps 48 for each of the half-shell shots 2 B on both sides of the block carrier 16 are arranged and each individual half-shell receptacle 1ab between them, with one at the cross-tensioners 48 existing centering projection 49 which extends vertically into a V-shaped bulge in the end face of the half-shell receptacle 2 B , press and center this.

13a shows the still empty block carrier 16 in the joining station 103.1 , It can be seen that on each side in each case a transverse tensioner 48 on an angled Auskragarm additionally a vertical clamping device 47 carries, and the transverse tensioner 48 in the transverse direction to the longitudinal direction of the block carrier 16 and the transport direction of the rail conveyors 25a , B can be moved between a spaced and a clamping position in the transverse direction.

Only in the longitudinal direction of the block carrier 16 last transverse tensioner 48 near the end flap 18 does not carry vertical clamping device.

For clarity, is in 13a on the left side only a transverse tensioner 48 shown, in practice, of course, there are all cross-tensioners 48 available as on the opposite side.

To insert the first, one-sided half-shell holder 2a , adjacent to the end stop 14 , are all cross-tensioners 48 from the block carrier 16 moved back, so that the gripper 32 '' with the half-shell holder 2a can drive in from the front along the side guides to the end stop ( 13b ).

Subsequently, the first two opposite transverse tensioners move 48 on the block carrier 16 to, as in 13c shown - or alternatively only the transverse tensioner 48 one side - and thus pinch the inserted, one-sided half-shell holder 2a between them. As 13c shows, then already the vertical clamping devices 47 centric over the positions, followed by cells 1 in the block carrier 16 according to 13d be positioned in contacting attachment to the first one-sided half-shell receptacle 2a , however, are the Spannvor directions 47 retreated to the top, in the not yet exciting position.

Subsequently, by means of the other gripper 32 ' according to 13d a first cell 1 in the first upright inner surface 13 the half-shell receptacle 2a Standing upright and contacting in the block carrier 16 positioned with the glue bead 15 against the inner surface 13 directed and even before releasing the gripper 32 ' by means of the vertical clamping device located above 47 clamped in this position.

As the 13e and 13f show is in the transverse tensioner 48 at the height of the upper gripping jaws 33a , B sufficient clearance available to the outer gripping jaw 33a when opening to be able to drive at a distance from the cell, as this outer gripping claw 33a a recessed recess as a contact surface to the cell 1 owns and over the longitudinal center of the cell 1 takes over.

In contrast, the other gripping jaw 33b - how better in 11c to recognize - formed only as a tip and does not even reach to the longitudinal center of the cell 1 so this gripping jaw 33b no or only a very small movement path in the transverse direction of the block carrier 16 must perform when opening.

Thus it is with this gripper 32 ' Although a parallel gripper, but the two gripping jaws move 33a , b to different lengths for opening and closing, or it moves only the one, longer projecting gripping jaw 33a ,

The second cell will be next to it in the same way 1 in the first one-sided half-shell holder 2a inserted, but with now rotated by 180 degrees gripper 32 ' so that now the short, designed as a top gripping jaw 33b again on the center line of the block carrier 16 that is, between the two rows of cells 1 , is located.

The outer claw 33a of the lower pair of claws moves into the free space 46 the lateral guidance 17b one, which is also sufficient for opening this lower outer gripping jaw 33a ,

Both the vertical clamping device 47 as well as the transverse tensioner 48 are preferably designed as pneumatic cylinders.

Now the two cells 1 The first row of cells are positioned and stretched and the gripper 32 ' is removed, drive according to 13g by means of the gripper 32 '' the next, this time two-sided half-shell shot 2 B zoom in and out of the block carrier 16 deposited at the appropriate position and last to the contacting end position to the first row of cells 1 moved up. As soon as this positioning is done, the two-sided cross-tensioners drive 48 close and clamp the half-shell holder 2 B between them, with the vertical centering projection 49 at the contact surface of the transverse tensioner 48 form-fitting centering in the prism-shaped depression 51 on the front sides of the two-sided half-shell receptacle 2 B intervenes.

The vertical clamping devices 47 these two transverse tensioners 48 are in turn still in the upward retracted position, so then turn the next cells 1 can be inserted underneath, positioned and then tensioned.

This process is repeated until the block 3 by inserting and tensioning the last, then one-sided, half-shell receptacle 2a completed and by approaching the last cross-tensioner 48 it is curious how in 13i shown, whereupon the end flap 18 by folding up the flap lever 18a , preferably using the last gripper used 32 '' happens, folded up and locked in this position.

If this in 13k State shown can all vertical clamping devices 47 moved away to the top and then all cross-tensioner 48 moved away to the side, so that the ready-stocked block carrier 16 becomes free.

Due to the defined distance between end stop 14 and end flap 18 of the block carrier 16 and the now further gelled coatings by contacting the cells 1 with the inner surfaces 13 also a surface distribution of the adhesive bead 15 over the entire inner surface 13 causes due to the tight positioning of the cells 1 to the inner surfaces 13 , are after closing the end flap 18 no impermissible changes in the layer thicknesses between the cells 1 and the inner surfaces 13 more to worry about so the block carrier 16 can be moved to the Vergussstation 103.2 according to 2 without the complete curing of the central electro-insulation layer 9b or the adhesive has to wait.

In the casting station 103.2 will - as in 15 shown - on the joined, in the block carrier 16 located block 3 a straight glue bead 50 each on both sides along each joint 21 (please refer 1b ) on the outside of the block between two oppositely directed. Half shell shooting 2a , b applied. This consists of non-hardening, thermally conductive adhesive and serves after removal of the cured block 3 from the block carrier 16 the lateral sticking each one (not shown) ribbed Kühlkör pers made of aluminum or another good thermal conductive material on each of the two outer sides of the block 3 ,

The casting station 103.2 essentially corresponds to the casting station 101.4 , especially with regard to the inclination of the casting nozzle 38 but only one of them is on the grouting unit 39 ' available.

Again, after applying the adhesive beads 50 on the one outside of the block 3 this together with the block carrier 16 by means of the lifting-turning unit 41 lifted, rotated 180 degrees, and on the rail conveyors 25a , b settled in the same longitudinal position so that the Vergussdüse 38 on the other side the adhesive beads 50 at the block 3 can attach.

This is the block 3 finished and can from the Vergussstation 103.2 be moved out, but remains in the block carrier 16 until complete curing of the adhesive as well as the central electrical insulation layer 9b between the cells 1 and the half-shell shots 2a , b.

After removal from the block carrier 16 this is empty along the turn annularly closed, usually rectangular conveyor line to the joining station 103.1 scaled back.
