Definitions
- the invention relates to a device for stacking segments of energy cells, comprising at least two feed devices, each designed and set up for feeding segments at a continuous feed speed, and at least one cell stacking device, designed and set up to take over the segments from the at least two feed devices and for stacking them on top of each other Segments to stack, wherein the cell stacking device comprises at least one removal device for taking over the segments and at least one delivery device for delivering the segments.
- the invention relates to a method for stacking segments of energy cells with the steps of feeding segments at a continuous feeding speed by means of at least two feeding devices, taking over the segments from the at least two feeding devices and stacking the segments on top of each other to form stacks by means of at least one cell stacking device, the segments be taken over by means of at least one removal device comprising the cell stacking device and delivered to or by means of at least one delivery device.
- the segments are regularly moderately pre-cut in a preliminary manufacturing process and then placed on top of each other in the stacks in the predetermined order and connected to one another.
- the anode sheets and cathode sheets are cut, for example, from an endless web and then placed individually at intervals on an endless web of separator material.
- This subsequently formed “double-layer” endless web made of the separator material with the anode sheets or cathode sheets placed on it is then cut into segments again in a second step using a cutting device, the segments in this case being formed in double layers by a separator sheet with an anode sheet or cathode sheet arranged thereon.
- the starting materials i.e. that is, the anodes or cathodes provided on endless webs as well as the separator material are separated into sheet form starting from the endless webs.
- the components essential for the energy cell are provided individually in sheet form in order to form and set them up into stacks with the appropriate order or volume.
- the endless webs of the separator material with the anode sheets and cathode sheets placed on them can also be placed on top of each other before cutting, so that an endless web with a first endless layer of the separator material with anode sheets or cathode sheets placed thereon and a second endless layer of the separator material is formed with anode sheets or cathode sheets placed thereon.
- Segments in the sense of this invention are therefore single-layer segments of a separator material, anode material or cathode material, double-layer, three-layer or even multi-layer segments of the structure described above.
- the only advantage of the known segments is that the anode material or cathode material is separated by at least one separator material in a multi-layer structure.
- Another known approach is a machine with continuously running material webs and clocked tools, such as cutting knives or tools for changing the pitch as well as transport means for forming cell stacks.
- clocked tools such as cutting knives or tools for changing the pitch as well as transport means for forming cell stacks.
- For the production of cell stacks there are, for example, devices and methods that provide different web-shaped materials by means of independent feed devices in order to separate them into predetermined segments using provided cutting devices.
- the isolated segments can then be stacked with individually movable delivery elements in a desired order by targeted corresponding displacements by the delivery elements in the desired order.
- a great deal of logistical effort is required to control the dispensing elements, with correspondingly high dynamics affecting the segments and the dispensing elements at the intended transport speeds. Due to the corresponding parameters, such devices tend to be highly susceptible to errors when stacking and to wear on the respective components.
- the supply of the material webs also requires independent means and devices for separating and providing the segments, which means that high investment costs are required and a correspondingly large installation space must be provided for the large number of separate device components.
- machines with clocked movements have limited performance.
- the parts with mass, such as holders and tools, must be constantly accelerated and decelerated. The processes determine the timing and a lot of energy is consumed.
- the mass of the moving parts cannot be reduced arbitrarily. Parts that move faster often have to endure higher loads and therefore become more complex and heavier.
- a condition for the high production output is a high production rate of the stacks of energy cells, which are formed from several segments of the type described above that are stacked on top of each other. To achieve very high production rates of energy cells and/or or energy storage, it is desirable to stack the manufactured segments at the highest possible production rate with the highest possible positional accuracy.
- the existing devices and methods do not enable flexible and precisely positioned stacking of segments at a high production speed.
- the known devices are designed either to produce stacks of segments at a high production speed or to form a specific sequence of segments into a stack.
- the formation of a stack from different segments or different starting materials for the segments cannot be achieved in a continuous process with high production output and reliable positioning of the segments to be stacked with the current devices and methods.
- the task remains to propose an appropriate procedure.
- the removal device is designed and set up to be drivable for a repeating, alternating movement consisting of acceleration and deceleration, and in that the removal device feeds the segments at the feed speed depending on a predetermined takeover sequence in each case from one of the takes over at least two feed devices, the removal device transferring the segments to the at least one delivery device in a delayed movement or at a standstill in order to form and set up a stack in a predetermined sequence of segments of the at least two feed devices.
- the device according to the invention ensures that the segments are taken over by the removal device at the feed speed of one of the at least two feed devices and are then transferred to the delivery device by delaying the movement of the removal device at a lower speed or even at a standstill.
- the design of the device with at least two feed devices enables, on the one hand, flexible transfer Taking segments from at least one of the feed devices and, on the other hand, continuous provision of the segments and subsequent stacking are ensured. This enables the provision of segments by means of at least one of the feed devices at a high transport speed, but with only a small load on the segments during transfer.
- the segments can be delivered to the delivery device with lower transverse forces acting on the segments.
- the transverse forces reduced when the segments are delivered to the delivery device are of particular importance, since the segments can thereby be stacked in the delivery device in a more precise position to form the stacks. In this way, abrasive relative movements in particular between a segment that has already been deposited and the segment currently in the delivery movement can be minimized.
- the feeding and delivery of the segments is of particular importance.
- the segments can be fed essentially simultaneously, so that the segments are made available to the removal device essentially simultaneously.
- the segments are also taken over essentially simultaneously by means of the removal device of the cell stacking device.
- the segments are preferably dispensed in a delayed movement or at a standstill in such a way that the segments are dispensed on a single stack in a predetermined sequence.
- the segments are further preferably delivered alternately into a stack by the at least two feed devices.
- segments with a different structure and/or a different material composition can preferably be provided to the removal device in order to form and set up a stack with an intended stacking sequence of different segments by means of the cell stacking device.
- a segment with a different sequence of anode sheet or cathode sheet and at least one separator sheet is provided by means of one of the at least two feed devices in order to form and set up a stack with a corresponding sequence of segments by means of the removal device.
- the segments can each be, for example, different individual sheets (anode sheet, cathode sheet or separator sheet).
- a continuous feed speed of the segments by means of the feed devices means that segments can be continuously provided at a predetermined feed speed.
- “continuous” does not immediately mean that the segments must be provided at a constant feed rate.
- at least one of the feed devices is designed and set up to run a swelling speed profile.
- additional means e.g. control and/or regulating means
- the segments can be delivered at a feed speed A and alternatively at a feed speed B.
- the at least two feed devices can be operated with the same or identical feed speed.
- a preferred embodiment is characterized in that the device comprises three feed devices, each designed and set up to feed segments at a continuous feed speed, the removal device taking over the segments in a predetermined takeover sequence from at least one of the three feed devices in order to create a stack in one to train and set up a predetermined sequence of segments.
- Three feed devices provide further variance in order to form a stack of several different segments. With three feed devices, for example, the starting materials for stacks of energy cells, anode sheet, cathode sheet and separator sheet, can each be fed independently in order to form and set up a stack in a predetermined sequence.
- Stacks can preferably be produced in this way, in which an anode sheet and a cathode sheet are covered by at least one separator sheet on the top and/or the bottom. More preferably, at least four feed devices can be provided, wherein in such a configuration the segments to be fed by means of the feed devices are preferably provided as an anode sheet, cathode sheet and two separator sheets.
- An advantageous development is characterized in that the removal device is formed by a rotatably driven rotating body, and the repeating alternating movement from the acceleration and deceleration is formed by an accelerated and decelerated rotational movement of the rotating body.
- the realization of the removal device as a rotatably driven rotating body has the advantage of a very high transfer speed of the segments from the removal device in a continuous feed movement. Furthermore, the use of the rotatably driven rotating body has the advantage of a very compact design of the cell stacking device.
- the rotatably driven rotating body is preferably designed and set up as a rotatably driven drum.
- the advantages of drums as a transport medium are well known. Surprisingly, the use of drums has also led to positive production speed and accuracy in the area of producing energy cells and as a removal device.
- the at least two feed devices can each be designed and set up as a drum barrel in the form of several drums connected in series, whereby the segments can be fed at a very high feed speed.
- the rotating body comprises at least one transfer stamp for receiving the segments, and the rotating body can be decelerated and accelerated during a revolution in accordance with the number of transfer stamps.
- the rotating body is preferably rotatable in such a way that the transfer stamp picks up the segments from different locations, that is to say from different feed devices, in accordance with a predetermined sequence and accordingly delivers the delivery device.
- higher demands are placed on the dynamics, since a comprehensive movement of the rotating body or the drum must be guaranteed.
- a single transfer stamp enables precise transfer and delivery of the corresponding segments, which means that, for example, the timing of the transfer and delivery of the segments is less complex, since a small number of possible control and/or regulation processes have to be taken into account.
- An expedient embodiment of the invention is characterized in that the rotating body comprises at least three transfer stamps, with more than two transfer stamps preferably being positioned at substantially the same angles to one another. which are arranged.
- the transfer rate of the segments by the rotating body can be increased or, conversely, the required rotational speed of the rotating body can be reduced for a predetermined number of segments to be transferred per unit of time.
- an electrical and/or electronic regulation/control can preferably be provided in order to design and set up a synchronous provision of the transfer stamps when the rotary body is used according to the invention.
- more than one segment can also be fed in parallel from the at least two feed devices to the removal device, whereby faster feed speeds and processing can be achieved using the device.
- four transfer stamps are advantageous, whereas in an alternative embodiment with three feed devices, five transfer stamps are advantageous.
- six transfer stamps are advantageous. The number of transfer stamps depends largely on the positioning of the feed devices depending on the arrangement of the stacking device or the rotating body with the corresponding feed devices and the subsequent delivery of the segments.
- the at least two transfer stamps can be variably arranged on the rotating body, since the rotation forms a desired arrangement of the rotating body, preferably by means of additional electrical and / or electronic control and / or regulating means, in a position- and time-specific manner on the at least two feed devices and sets up.
- the device When delivering a segment while at a standstill, the device should preferably be designed in such a way and the respective devices should be positioned relative to one another in such a way that the remaining segments are not positioned in the receiving areas.
- the number of transfer stamps corresponds at least to the number of feed devices, with the number of transfer stamps preferably corresponding to a plurality of feed devices.
- four transfer stamps are each arranged opposite one another, i.e. at an angle of essentially 90 degrees in relation to the axis of rotation of the rotating body. More preferably, the two feed devices are aligned with one another in such a way that they take over the feed at the same time Ensure segments using the transfer stamps. In this way, the transfer stamps are located in the transfer station at the same time and when a segment is delivered, none of the transfer stamps is preferably in the transfer station with the removal device.
- the proposed further development means that the transfer station and the transfer station are offset from one another in such a way that a continuous stacking process is ensured without two transfer stamps having to provide delivery at the same time.
- the transfer stamps each have a transfer surface which is in the shape of a circular arc section in the cross section of the rotating body, and the transfer surfaces of the transfer stamps are arranged on the same diameter in cross section.
- the transfer surfaces of the transfer stamps thus form a transfer radius and thus pass through the transfer station and the transfer station preferably at the same diameter in relation to the rotating body.
- the removal device comprises at least two support zones which are arranged at a distance from one another in the circumferential direction and extend in a length Y in the circumferential direction for taking over the segments at the at least two transfer stations and for delivering the segments at the delivery point.
- Free zones extending in a length Z in the circumferential direction are further preferably provided between the support zones. The free zones are deliberately not designed to take over segments and, for example, enable the at least one transfer station and/or at least one of the feed devices to be passed through without a segment being delivered to the transfer station and/or one of the feed devices.
- the carrying zones and the free zones are preferably arranged in such a way that the removal device passes the delivery device and/or at least one of the at least two transfer stations with a free zone in a takeover phase at the at least two transfer stations during which a segment is taken over from a carrying zone.
- Such an arrangement and design of the cell stacking device enables the segments to be stacked at a very high piece rate, in that the removal device takes over the segments in a continuous rotational movement over the support zones in the at least two transfer stations by being designed as a rotating body with the support zones and the free zones.
- the proposed design of the cell stacking device results in improved acceptance and transfer of the segments and thus improved stacking of the segments.
- the removal device can optimize an improved takeover of the segments from the feed and the delivery and stacking of the segments in their movement behavior when taking over and handing over the segments, by individually designing their movement behavior in the positions when they pass the transfer station and at least one transfer station with the support zones.
- the length Y of one or each support zone is smaller, equal to or greater than the length Z of one or each free zone. If the length Y of the carrying zone is smaller, this is advantageous for the transfer of the segments, since in this case, due to the larger length of the free zone, a larger angle of rotation is available for adapting the movement behavior of the removal device until the segment is taken over and transferred. If the length Y of the support zones is equal to the length Z of one or each free zone, the advantage of a change in the movement behavior that is as uniform as possible, in particular with identical accelerations and decelerations of the removal device, can be achieved. If the length Y of the support zones is greater than the length Z of the free zones, this is advantageous with regard to the capacity of the removal device, since the lateral surface of the rotating body can be designed to accept and transfer a larger number of segments.
- the lengths Z of the free zones between the supporting zones are the same or different. If the length Z of the free zones is the same, repeating movements of the rotating body that are as similar as possible can be achieved between the takeover and the transfer of a segment and vice versa. If the length Z of the free zones are different, individually different movement processes can be implemented, whereby e.g. B. Deviations in the feeding movements or the removal movements of the segments can be taken into account.
- one or each support zone has a take-over surface. Thanks to the take-over area, the segments can be placed flat on the support zones. hold and be transported by the rotating body from at least one of the transfer stations to the transfer station. This allows a particularly gentle transport of the segments with the lowest possible local area-related maximum forces acting on the segments.
- one or each free zone is formed by a radially inwardly extending recess on the rotating body.
- the proposed design of the free zones creates free spaces on the rotating body, which allows a collision-free overlapping relative movement, for example.
- the mass of the rotating body to be moved can be reduced, which in turn simplifies the movement control and reduces the energy required to drive the rotating body.
- one or each free zone has a radially inwardly offset boundary to one or each support zone.
- the radially inwardly offset boundary creates a clearly defined spatial separation of the free zone from the supporting zone, which z. B. enables simplified detection of the rotational movement of the rotating body.
- a further expedient embodiment of the invention is characterized in that the at least one dispensing device has a linearly movable receptacle which transports the stacks away from the removal device in the direction of the surface normal of the segments. Thanks to the linearly movable holder, the stacks and/or the segments stacked therein can be transported away without acting transverse forces. This prevents the segments or stacks from losing their precise positioning during transport.
- “acceptance” of the dispensing device is to be understood as meaning, for example, a means which forms and sets up a removal of the segments from the removal device by means of a vacuum supply. The removal can be designed, for example, as a storage lever and set up to remove the segments from the removal device.
- a preferred development of the invention is characterized in that the removal device and/or the receptacle of the at least one dispensing device have one or more vacuum lines which can be subjected to negative pressure, which before supporting the takeover of the segments by the removal device from at least one of the feed device and/or by the at least one delivery device from the removal device and the transport on the removal device by applying negative pressure. Thanks to the vacuum lines that can be subjected to negative pressure, the transfer of the segments and the transport of the segments on the removal device can be achieved with very low forces acting on the segments. Furthermore, the forces exerted on the segments can be controlled very easily by switching the negative pressure on and off in the vacuum lines. So can e.g. B.
- the takeover of the segments by the removal device from the at least two feed devices can be controlled very easily by switching on negative pressure in the vacuum lines of the removal device and switching off the negative pressure in the vacuum lines of the feed devices in a transfer position.
- the segments are then delivered from the removal device to the delivery device in an analogous manner by switching off the negative pressure in the vacuum lines of the removal device and switching on the negative pressure in the vacuum lines of the receptacle of the delivery device.
- a holding vacuum is applied to one or each vacuum line of the removal device opening into a support zone, which is switched off with a delay when or during the transfer of the segment to the delivery device and a segment to be transferred is withdrawn against the holding vacuum that is still at least partially applied, which is a ensures fixed, precise positioning of the segment to be transferred and helps prevent position changes caused by any floating or falling movements.
- An expedient embodiment of the invention is characterized in that at least one of the at least two feed devices comprises a buffer device for the delayed provision of the segments and/or a preliminary product of the segments, the preliminary product preferably being an endless web comprising a plurality of segments.
- Such buffer devices enable a needs-based supply of the segments and/or a preliminary product of the segments in order to provide the segments depending on the other device components and with the device steps associated therewith.
- the buffer device is preferably designed and set up to adapt a distance of the segments during feeding in such a way that the distance of the feeding can be changed. In this way, the segments have to cover a greater distance, which means that the segments can be made available to the removal device with a delay, for example.
- the Buffer device has a tensioning mechanism in order to set a desired web tension for (endless) webs or for (endless) webs with segments.
- the buffer device is preferably designed and set up as a so-called “dancer”.
- At least one of the at least two feed devices comprises a cutting device, designed and set up to cut segments and/or a preliminary product of the segments, the preliminary product preferably being an endless web comprising a plurality of segments.
- a cutting device designed and set up to cut segments and/or a preliminary product of the segments, the preliminary product preferably being an endless web comprising a plurality of segments.
- a further preferred development of the invention is characterized in that at least one of the at least two feed devices comprises at least one sub-device, designed and set up to continuously provide segments with a predetermined distance from one another to the cell stacking device.
- the segments can be fed to the removal device at a predetermined spacing, the spacing of the segments increasing in particular in the course of transport or feeding by means of the feed device.
- the feed of the segments to the removal device can be controlled and/or regulated by the partial device, since the provision of the segments to the removal device at a predetermined spacing is determined by the feed speed.
- the removal device can transfer the segments to the at least one delivery device at a predetermined timing with a delayed movement or at a standstill and the order of provision can be changed based on the transfer by the feed devices.
- This leads to efficient use of the existing feed device by means of the removal device and, on the other hand, enables a desired sequence in the delivery of the segments.
- the dividing device is preferably designed and set up as a pitch changing drum.
- a further advantage of the dividing device is that the cell stacking devices or the removal device can be taken over and stacked in a predetermined sequence by means of the removal device due to the division or spacing of the supplied segments.
- segments of the number A on a first feeder and segments of the number B on a second feeder can be different spacings.
- proper stacking can preferably be carried out in a predetermined sequence.
- the spacing of segments on the two feed devices can be adjusted as required in order to provide a desired stacking sequence.
- a further advantage of the at least one partial device is that segments are delivered by means of the removal device at a lower stacking rate than they are fed to the removal device by means of the feed devices. This means that the conveying rate of the feed devices can be designed to be correspondingly high, and the stacking rate can at the same time be designed to be correspondingly low for high positional accuracy of the stacked segments and thus the stack itself.
- a change in pitch is to be understood in particular as a change in the spacing of the segments from one another on the corresponding feed devices.
- Such changes in division serve, for example, either to increase or decrease the distance between the segments from one another, in particular in order to arrange them on the removal device by means of the feed devices depending on the movement of the rotating body and / or the arrangement and number of the transfer stamps.
- At least one of the at least two feed devices comprises at least one transfer drum, designed and set up to transfer segments to the cell stacking device and/or to take over segments from the buffer device or the cutting device.
- Drum-shaped transfer devices are particularly suitable for continuous transfer processes with high process speeds.
- the at least one transfer drum is also designed and set up for delayed provision of the segments.
- the transfer drum enables the segments to be spaced apart by means of the transfer drum, for example by the transfer drum having a different speed or a different diameter to a preferably upstream further rotating body and/or a drum which is intended to provide the segments.
- the task is also achieved by the method mentioned at the beginning in that the removal device is driven to a repeating, alternating movement consisting of acceleration and deceleration, and that the removal Measuring device takes over the segments in the feed speed depending on a predetermined takeover sequence from one of the at least two feed devices, with the removal device transferring the segments to the at least one delivery device in a delayed movement or at a standstill in order to create a stack in a predetermined sequence of segments to train and set up at least two feed devices.
- the segments are taken over by the removal device at the feed speed of the at least two feed devices in a continuous feed and then by delaying the movement of the removal device at a lower speed or even at a standstill to the delivery device for stacking the segments.
- the at least two feed devices ensure flexible and at the same time efficient provision of segments, with different segment combinations preferably being provided.
- the cell stacking device forms an interface between the continuous feeding of the segments via the feeding devices and the stacking of the segments.
- a further development is characterized in that three feed devices are provided, each of which feed the segments at a continuous feed speed, the segments being taken over by one of the three feed devices in a predetermined takeover sequence from the removal device in order to form a stack in a predetermined sequence of segments to train and set up.
- the removal device has a controllable drive device, which is controlled in such a way that the removal device is accelerated to take over the segments of the at least two feed devices and is decelerated to deliver the segments to the delivery device.
- An expedient embodiment of the invention is characterized in that the removal device is formed by a rotatably driven rotating body, and the repeating alternating movement from the acceleration and deceleration is formed by an accelerated and decelerated rotational movement of the rotating body.
- a further preferred embodiment of the invention is characterized in that the rotating body comprises at least one transfer stamp for receiving the segments, with two or more transfer stamps being arranged at the same angles to one another, and that the rotating body decelerates during a revolution in accordance with the number of transfer stamps and is accelerated.
- a further expedient embodiment of the invention is characterized in that the stacks are transported away from the removal device in the direction of the surface normal of the segments by means of a linearly movable receptacle having the at least one delivery device.
- a preferred development of the invention is characterized in that the segments and/or a preliminary product of the segments are delayed by means of at least one buffer device comprising the at least two feed devices are provided, the preliminary product preferably being an endless web comprising a plurality of segments.
- a further expedient embodiment of the invention is characterized in that the segments and/or a preliminary product of the segments are cut by means of at least one cutting device comprising the at least two feed devices, the preliminary product preferably being an endless web comprising a plurality of segments.
- a preferred development of the invention is characterized in that the segments of the cell stacking device are continuously provided at a predetermined distance from one another by means of at least one partial device comprising the at least two feed devices.
- At least one of the at least two feed devices comprises at least one transfer drum so that the segments are transferred to the cell stacking device and/or so that the segments are taken over by the buffer device or the cutting device.

Furthermore, corresponding openings of vacuum lines that can be subjected to negative pressure can also be provided in the lateral surfaces of the transfer drums 23.

- the buffer device 32 is preferably designed and set up to adapt a material web comprising the segments 11, which is designed, for example, as an endless web 19, during the feed in such a way that the route of the feed can be changed.
- the segments 11, for example have to cover a longer distance, whereby the segments 11, for example, can be made available to the removal device 17 with a delay, especially if a continuous transport speed given is. If the route is shortened, the segments 11 of the feed can be provided in a correspondingly accelerated manner. More preferably, the buffer device 32 comprises a tensioning mechanism in order to set a desired web tension in (endless) webs 19 or in (endless) webs 19 with segments 11.

In order to provide the sequence synchronously depending on the intended transfer stamps 25, it may be useful to arrange the segments 11 at a distance from one another so that the movement of the rotating body 24 to be carried out has a lower degree of complexity.
- the segments 11 of a first feed device 12 can be stacked at a lower stacking rate than the segments 11 of a second feed device 13. This means that the conveying rate of the feed devices 12, 13 can be adjusted accordingly to one another, and the stacking rate can at the same time be correspondingly low for high positional accuracy of the stacked segments 11 and thus the stack 16 itself are laid out.
- the device 10 according to the invention can preferably have a sub-device 33 for each of the feed devices 12, 13, 14, so that the segments 11 can be operated with a high conveying rate in the feed device 12, 13, 14 and at the same time the segments 11 are stacked in a precisely positioned position, since the stacking rate of the segments 11 in the cell stacking device 15 can be significantly lower than the feed rate of the segments 11 in the feed devices 12, 13, 14 due to the solution according to the invention.
- the material webs/endless webs 19 or the segments 11 are “divided”, a distance between the cut segments 19 and / or a delay in the feed speed is generated in order to then provide the segments 11 on the cell stacking device 15 in a specific sequence and speed.

- the cut segments 11 are fed by means of the corresponding feed device 12, 13, 14.
- the counter drum 22 preferably also functions as a transport drum in order to transport the segments 11 and/or the endless webs 19 containing the segments 11 in the transport direction.
- the segments 11 have first been cut into segments 11 by the cutting device 20.
- the material webs 19 are preferably each a separator material web, an anode material web and a cathode material web, each of which is cut into segments 11 by means of the cutting device 20, so that separator, anode and cathode sheets can preferably be stacked into stacks 16 by means of the cell stacking device 15 .
- the feed devices 12, 13, 14 also each have a transfer drum 23 in FIGS. 6 and 7, which is designed and set up to transfer the segments 11 to the cell stacking device 15.
- the transfer drum 23 and the counter drum 22 are designed as a single drum, so that synergy effects can be used in the best possible way.
- the transfer drum 23 By means of the transfer drum 23, the cut segments 11 can be transferred to a collecting drum 35 which further encompasses the cell stacking device 15 and is designed and set up to take over the segments 11 supplied by the three feed devices 12, 13, 14 from the transfer drums 23.
- the collecting drum 35 in turn transfers the segments 11 to a drum barrel 36 with several distribution drums 37, on which the segments 11 are z. B. be held by suppression.
- the distribution drums 37 comprising the cell stacking device 15 are designed and set up to distribute the segments 11 in order to take them over by the removal device 17 in a predetermined takeover sequence by the corresponding takeover stamps 25.
- the removal device 17 carries out a repeating, alternating movement consisting of an acceleration and a deceleration in order, on the one hand, to take over the predetermined segments 11 from the distribution drum 37 in a precise position and then to hand them over to the corresponding delivery device 18 in a delayed movement or at a standstill.
- the drum run 36 provides a distribution of the segments 11 of the three feed devices 12, 13, 14, whereby a stack 16 can be formed from segments 11 in a predetermined sequence by means of each of the removal devices 17.
- each of the removal devices 17 produces a stack 16 of segments 11 with the same sequence, where more preferably, every second segment 11 taken over is a separator sheet and an anode or cathode sheet can be taken over alternately between them.
- separator sheets are fed onto the collecting drum 35 at least in twice the number as anode or cathode sheets or in total at least in the same number.
- the feed speed of the feed device 12, 13, 14 to feed the separator segments 11 is, for example, faster than the feed speed of the feed device 12, 13, 14 to feed the anode or cathode segments 11. Segments 11 on the drums provided or on are further preferred in the provided facilities through suppression, at least temporarily.
