Definitions
- the invention relates to a system with a stacking aid and a plurality of batteries arranged in the stacking aid, in particular AGM batteries, wherein the stacking aid has a support element and two cheeks aligned orthogonally thereto, which receive the support element between them, wherein the support element receives a plurality of batteries arranged in rows one above the other, wherein between two rows of batteries following one another in the vertical direction a positioning aid is arranged, which has a plate equipped with an extension serving as a stop.
- a generic system is known, for example, from DE 102022 118 386 A1, which relates to a system in particular for AGM batteries.
- AGM batteries are rechargeable batteries that have electrode plates arranged in a housing.
- the housing is rectangular in cross-section and has first side walls that run parallel to one another on the one hand and second side walls that run parallel to one another on the other.
- the electrode plates held by the housing are aligned parallel to the first side walls of the housing.
- the second side walls of the housing run perpendicular to the electrode plates.
- a fleece that serves as a separator is arranged between two adjacent electrode plates.
- the housing also holds an electrolyte that surrounds the electrode plates. In the case of AGM batteries, this is in bound form and is provided by the fleeces located between the electrode plates. The fleeces therefore not only serve as separators, but also as an electrolyte bond.
- the electrolyte present in AGM batteries in bound form makes it possible to store AGM batteries lying down, i.e. on one of the side walls of the housing without the risk of electrolyte leaking from the housing.
- the pressure inside the housing of an AGM battery can increase, particularly during a charging cycle, which repeatedly leads to a reduction in contact between the electrode plates and fleeces, reducing the service life.
- the loading condition caused by the compressed fleece is therefore the main cause of the bulging of the casings.
- Comparable systems are also known from US 6,641,951 B1 and EP 0 922 308 B1.
- stacking aids are used to accommodate AGM batteries, which house the AGM batteries held by them, with supporting elements in the form of intermediate and/or insert floors being provided, which are connected to laterally arranged cheeks in a force-transmitting manner.
- the AGM batteries are therefore clamped at least between a base element and an intermediate and/or insert base on the one hand and an intermediate and/or insert base and a cover element on the other, whereby the base element, the cover element and the at least one intermediate and/or insert base counteract any unwanted bulging of the housing of an AGM battery.
- the force is dissipated via the side cheeks of the stacking aid, which are operatively connected to the at least one intermediate and/or insert base in a force-transmitting manner.
- DE 10 2022 118 386 A1 proposes a generic system, according to which the cheeks that hold the battery support element between them are designed not to perform a supporting function and to serve exclusively as lateral protection for the batteries held by the support element. Accordingly, only the support element on the stacking aid side serves to securely position the batteries provided by the system. The cheeks arranged on it, however, serve exclusively as lateral protection against falling out and do not perform a supporting function.
- the stacking aid known from DE 10 2022 118 386 A1 is simpler and cheaper to construct and, moreover, easier to assemble and dismantle at the installation site.
- DE 10 2022 118 386 A1 proposes the use of a positioning aid.
- a positioning aid is arranged between two rows of batteries that follow one another in height. It is preferably designed in the manner of a plate and provides an extension that serves as a stop, which, when used as intended, serves to align the batteries interacting with the positioning aid in a positionally precise manner.
- the positioning aid is not connected to the cheeks of the stacking aid in a force-transmitting manner, so that when used as intended, no force is introduced via the positioning aids into the side cheeks of the stacking aid.
- the invention proposes a generic system which is characterized in that the positioning aid is designed in two parts and has a first section and a second section which are detachably connected to one another, wherein a connecting piece is provided which, in the final assembled state, engages in a form-fitting manner in a first recess provided by the first section and in a second recess provided by the second section.
- the system according to the invention and the stacking aid according to the invention are used in particular to accommodate AGM batteries, wherein an AGM battery has a housing with first side walls and electrode plates arranged in the housing, which are aligned parallel to the first side walls of the housing.
- the support element of a stacking aid accommodates a plurality of AGM batteries arranged in rows one above the other, wherein both the support element and the first side walls of the housings of the AGM batteries are aligned parallel.
- a positioning aid which is designed in two parts.
- the positioning aid has a first section on the one hand and a second section on the other. In the final assembled state, these two sections of the positioning aid are connected to one another and can be removed. It is therefore possible to disassemble the positioning aid, in which case the positioning aid is broken down into two sections.
- a connecting piece is provided to connect the two sections of the positioning aid.
- the positioning aid therefore has a total of three parts, namely a first section, a second section and a connecting piece by means of which the two sections can be detachably connected to one another.
- the individual batteries held by the stacking aid are placed in rows on top of each other, so that the positioning aids provided between the individual rows of batteries are subjected to force in accordance with the weight. This creates inherent stability, which also prevents a connecting piece from accidentally coming loose from the recesses provided by the sections.
- the positioning aid designed according to the invention can be assembled in a simple manner by placing the two sections of the positioning aid on a fully formed battery row. After correct positioning The two sections are connected by inserting the connecting piece. The positioning aid is then fully assembled and positioned precisely and securely between the two sides of the stacking aid, so that batteries can then be placed on the positioning aid in the intended manner.
- the cheeks accommodate a positioning aid between them, wherein the positioning aid and the cheeks are designed without any connection.
- a connection between the cheeks on the one hand and a positioning aid on the other hand is not provided.
- the force is transferred solely by the support element provided by the stacking aid, on which the individual rows of batteries rest, including the positioning aids arranged between the individual rows of batteries.
- the two sections of a positioning aid are placed on a battery row already held by the stacking aid and positioned one behind the other in the lengthwise direction.
- the cheeks are preferably equipped with extensions that serve as stops for the sections of the positioning aid. These cheek-side extensions are preferably located on the rear edge of the respective cheeks in the loading direction.
- the sections of the positioning aid can be placed against these extensions so that the user can easily find the correct alignment of the two sections.
- the connecting piece for connecting the two sections can be inserted into the respective recesses provided by the sections. This is done without tools, so that a proper, i.e.
- the positioning aid serves to align the batteries of this row of batteries in the intended manner.
- the two sections of a positioning aid are designed to be identical to one another. This design also simplifies assembly in particular, since the user does not have to distinguish between differently designed sections. Since the two sections are designed identically, storage and order picking are also simplified. To form a positioning aid according to the invention, only two identically designed sections are required on the one hand and a connecting piece on the other.
- the first recess and the second recess each provide an undercut.
- This The undercut acts in the longitudinal extension of the positioning aid and enables a mechanical connection of the two sections, whereby the connection is not only positive-fitting, but also force-fitting due to the undercut in the longitudinal extension of the positioning aid. This ensures that the two sections cannot separate from one another unintentionally, at least not in the direction of the longitudinal extension of the positioning aid. Since batteries rest on a positioning aid in the final assembled state and the positioning aid is therefore weight-loaded following the force of gravity, the two sections are also prevented from coming loose in the vertical direction due to the batteries resting on the positioning aid. As a result, a permanently secure connection of the two sections of the positioning aid is ensured.
- the connecting piece has a geometry designed in the manner of a dovetail.
- An undercut geometry is thus formed in the simplest possible way.
- the connecting piece is axially symmetrical due to the dovetail design, which simplifies assembly, since the connecting piece can also be inserted into the recesses of the sections in a mirror-inverted manner as intended.
- a positioning aid is designed to be slip-resistant on its underside, which in the finally assembled state faces a row of batteries provided in the vertical direction below the positioning aid.
- This design is particularly advantageous because it provides anti-slip protection between a row of batteries already inserted into the stacking aid on the one hand and a positioning aid placed on top of it on the other. This ensures that the positioning aid does not move accidentally when it is fitted with batteries.
- the anti-slip protection applied to the underside of the positioning aid ensures that the positioning aid does not move accidentally in relation to the stacking aid when batteries are fitted. This also ensures that the positioning aid ensures that the batteries held by the positioning aid are aligned precisely and securely.
- the underside of the positioning aid is provided with an anti-slip coating.
- the preferably provided anti-slip feature of the positioning aid is accordingly achieved by equipping the underside of the positioning aid with an appropriate coating.
- This coating can either be formed as one piece with the positioning aid or applied as an additional coating to the underside of the loading aid.
- the decisive factor is that the anti-slip coating achieves a frictional connection between a positioning aid and a row of batteries arranged vertically below it.
- the coating is designed in strip form and is applied to the underside of the positioning aid.
- a strip-shaped coating can be provided, for example, by a strip element, for example a sandpaper strip element, which is applied to the underside of the positioning aid by gluing.
- a strip element for example a sandpaper strip element
- Each section of the positioning aid is equipped with a corresponding coating, for example such a sandpaper strip element.
- the coating runs along the rear edge of the positioning aid in the width direction.
- the housings of the batteries are made of plastic and are typically manufactured as injection-molded parts. In order to enable demolding, the housings are designed to be tapered. If the batteries equipped with such housings are now stacked vertically on top of each other, the design-related shape of the housings of the batteries results in a housing stack that is not vertical, but rather curved.
- the inventive The positioning aids provided are of no use, as they are not connected to the side cheeks of the stacking aid in a force-transmitting manner. Rather, the positioning aids absorb the curvature of the stack, so that as a result the batteries picked up by the stacking aid deviate in height from an exact, vertically stacked stack. This increases the risk of the batteries tipping over and, moreover, the batteries arranged on top of each other give an unattractive visual impression, as they are "crooked” in relation to the vertically aligned cheeks of the stacking aid.
- the inventive application of a strip-shaped coating that runs along the rear edge of the positioning aid provides a remedy here, since this coating, which is additionally applied to the underside of the positioning aid, compensates for the conical shape of the battery housing. Despite a lack of a force-transmitting connection between the positioning aids and the cheeks, this ensures that individual batteries can be stacked vertically on top of one another. This is because the positioning aid, together with its coating applied to the rear edge, makes it possible to compensate for the stacking offset in the vertical direction caused by the conical design of the battery housing, so that the result is that individual batteries can be stacked vertically to the support element of the stacking aid.
- the proposed design of a coating of the positioning aid is protectable in itself, which is why the invention proposes a system with a stacking aid and a plurality of batteries arranged in the stacking aid, wherein the stacking aid has a support element and two cheeks aligned orthogonally thereto, which receive the support element between them, wherein the support element receives a plurality of batteries arranged in rows one above the other, wherein a positioning aid is arranged between two rows of batteries which follow one another in the vertical direction, which has a plate equipped with an extension serving as a stop, wherein the positioning aid is designed with an anti-slip coating which is designed in strip form and which runs along the rear edge of the positioning aid in the loading direction.
- a positioning aid for the spaced arrangement of adjacent batteries serve two functions. Firstly, they serve as guide elements and thus make it easier to insert batteries into the stacking aid. Secondly, these spacers ensure that batteries arranged one behind the other in a row are spaced apart from one another so that air can circulate between adjacent batteries for the purpose of cooling them.
- a spacer is a strip body.
- This type of spacer design supports ease of assembly, since a strip body provides a type of guide rail on the battery side, along which the battery can be guided during assembly or disassembly.
- Two spaced-apart strip bodies have a distance between them that corresponds to the width of a rechargeable battery. This means that there is double guidance with respect to a battery to be accommodated by the positioning aid during assembly.
- a strip body is attached to the top of the positioning aid, which is opposite the bottom of the positioning aid, for example by gluing, welding, screwing and/or the like.
- a section of a positioning aid can accommodate four batteries arranged in a row one behind the other.
- the section of a positioning aid has three strip bodies attached to the top.
- more or fewer strip bodies can also be provided.
- the decisive factor is that these are attached to the top of a positioning aid, whereas the anti-slip feature already described is formed on the bottom of the positioning aid. This ensures that the positioning aid cannot move relative to the row of batteries located underneath it in the final assembled state and that batteries to be accommodated by the positioning aid can be properly aligned in relation to the positioning aid.
- the positioning aid not only has the individual strip bodies for aligning a battery, but also the already the extension mentioned at the beginning, which serves as a stop. Batteries to be picked up by a positioning aid can therefore be guided up to the stop on this extension, whereby a longitudinal guide, ie a guide in the loading direction of the stacking aid, is provided by the individual strip bodies of a positioning aid.
- a positioning aid has a plate and a border edge arranged on the plate, wherein the border edge extends along the rear edge in the loading direction and the two front edge edges.
- the edge edge therefore has the extension described above which serves as a stop and extends in the longitudinal direction of the rear edge.
- Edge edges are also provided on the front side, preferably for each section of the positioning aid. This allows all batteries accommodated by a section of a positioning aid to be guided and secured in position, so that as a result of two sections connected to one another to form a positioning aid, all batteries accommodated by the positioning aid in the final assembled state are held securely in position. Batteries accommodated on the front side of a section are therefore fixed in position by the associated front edge on the one hand and the strip body adjacent to this front edge on the other. In any case, all batteries accommodated by a section are supported on both sides.
- the invention further proposes a positioning aid with the features already mentioned.
- a positioning aid provides the advantages already described above.

- Fig. 15 shows a schematic perspective view of a system according to the invention with a fully equipped stacking aid.
- Fig. 12 shows a stacking aid 2 of a system 1 in a schematic perspective view, which stacking aid 2 serves to accommodate a plurality of batteries 3 when used as intended, as can be seen, for example, in Figures 14 and 15, each of which shows a system 1.
- Figures 12 to 15 show a generic stacking aid 2 or a generic system 1, as are previously known from DE 102022 118 386 A1.
- the stacking aid 2 according to Fig. 12 has two U-shaped base bodies 6 arranged one above the other in the height direction 16, one of which is shown in a schematic perspective view in Fig. 13 in isolation.
- a U-shaped base body 6 has a support element 7 which is arranged between two cheeks 8 and 9.
- the support element 7 is arranged at one end on the cheek 8 and the other end on the cheek 9.
- a base body 6 is thus formed which is U-shaped.
- the support element 7 has two tubes 11 with a rectangular cross-section. These two tubes 11 are arranged at a distance from one another in a direction transverse to the longitudinal extension 12 of the tube, thus forming a gap between them.
- the tubes 11 of the support element 7 are each screwed to the associated cheeks 8 and 9 at their ends.
- a material-locking connection by welding can also be provided, in particular in the case of pre-assembly by the manufacturer.
- only two base bodies 6 in accordance with the design according to Fig. 2 need to be arranged one above the other in the height direction 16 in order to form the stacking aid 2 shown in Fig. 12.
- a base body 6 can also be used on its own as a stacking aid 2, as shown in Fig. 13.
- the cheeks 8 and 9 of the stacking aid 2 can be designed to be correspondingly long in the vertical direction.
- a stiffening element 13 is also provided. In the embodiment shown, this is designed as a simple flat material that couples the two cheeks 8 and 9 to one another.
- a support element 7 is equipped with connecting connections 15 on its flat side facing away in the vertical direction 16 in the associated cheeks 8 and 9. These connecting connections 15 are used in particular for the exchangeable arrangement of spacers 14 serving as feet.
- spacers 14 serving as feet.
- the connecting connections 15 of the upper support element 7 in the vertical direction 16 remain unused.
- the front sides of the cheeks 8 and 9 also have corresponding connecting connections 15, whereby in the final assembled state the front sides of the cheeks 8 and 9 facing the ground at the installation site are equipped with corresponding spacers 14, as can also be seen in Fig. 12.
- the stacking aid 2 when used as intended, accommodates a plurality of batteries 3 arranged one above the other in rows 10 in the vertical direction 16, lying in the embodiment shown.
- Each AGM battery 3 has a housing 4 with first side walls 5.
- electrode plates are arranged, wherein the first side walls 5 and the electrode plates are aligned parallel.
- the AGM batteries are stacked lying on top of each other, with the first side walls 5 of the respective housings 4 as well as the support element 7 supporting the AGM batteries 3 being aligned horizontally.
- This alignment ensures that, on the one hand, the prestressing of the AGM separators does not lead to a housing bulging in the vertical direction 16 and, on the other hand, that there is no possible housing bulging in the vertical direction 16 even when an AGM battery is being charged as intended.
- the system 1 successfully counteracts such unwanted bulging of the housing by arranging the AGM batteries 3 held by the stacking aid 2 one above the other in the vertical direction 16, so that the weight of each AGM battery 3 alone causes them to be compressed in accordance with gravity, so that unwanted bulging of the housing is reliably counteracted.
- the stacking aid is designed to have no further support elements 7, which hold the AGM batteries 3 and are coupled to the cheeks 8 and 9 in a force-transmitting manner. All AGM batteries therefore rest solely on the support element 7 provided at the bottom in the vertical direction 16, in accordance with gravity, as can be seen from a look at Figures 14 and 15 in particular.
- the cheeks 8 and 9 do not perform any supporting function and only serve to secure the AGM batteries 3 held by the stacking aid 2 against accidental sideways falling out, for example as a result of a shock or against accidental mechanical forces from the outside.
- the AGM batteries of this further row 10 are supported by the Positioning aid 18 is held in a precise and secure position.
- a positioning aid 18 then follows in the height direction 16, followed by a further row 10 of AGM batteries, until the stacking aid 2 is completely filled with AGM batteries 3, as can be seen from the illustration in Fig. 15.
- the stacking aid 2 is then loaded with AGM batteries in the loading direction 35, as can also be seen from the illustration in Fig. 15.
- a positioning aid 18 is designed in two parts and has a first section 19 and a second section 20. In the final assembled state, these two sections 19 and 20 are detachably connected to one another, for which purpose a connecting piece 21 is provided.
- Fig. 1 shows an example of a section 19 or 20 in a schematic plan view from above. Two such sections are provided to form the positioning aid 18, as can be seen in particular from the illustration in Figures 5 and 6.
- a section 19 or 20 of the positioning aid 18 has a plate 25.
- This plate 25 provides a top side 31 and a bottom side 30.
- sections 19 and 20 accommodate AGM batteries 3 carried by the positioning aid 18 with their respective top sides 31. This is shown, for example, in Figures 9, 10 and 11.
- a section 19 or 20 of the positioning aid 18 also has a border edge 26 attached to the plate 25.
- the plate 25 and the border edge 26 can preferably be formed as one piece.
- a design of the plate 25 together with the border edge 26 arranged thereon is preferred to be made of plastic.
- Each section 19 or 20 also has recesses, namely a first recess 22 and a second recess 23.
- the recesses 22 and 23 facing one another serve to positively accommodate a connecting piece 21, as can be seen from a look at Figures 1 to 6.
- the two sections 19 and 20 forming a positioning aid 18 are positively connected to one another by means of the associated connecting piece 21. This connection can be assembled or disassembled without tools, which enables simplified handling by the user.
- Each section 19 or 20 has spacers 32 on its upper side 31 in the form of strip-shaped strip bodies.
- the distance between two adjacent spacers 32 is the housing width of a battery held by the positioning aid 18 in the intended use case.
- the distance between two spacers 32 is therefore to be selected depending on the size of the batteries to be held by the stacking aid 2. It is, for example, 175.5 mm.
- a section 19 or 20 of a positioning aid 18 shown in Fig. 1 serves to accommodate four accumulators or batteries 3. Therefore, a total of three spacers 32 are provided, wherein the outer spacers 32 each interact with the associated front-side web 27, so that in the final assembled state an accumulator is arranged between an edge-side spacer 32 and the associated front-side web 27.
- a strip element 34 with a coating 33 is arranged on the underside 30 of each section 19 or 20 in the region of the rear edge 36 in the loading direction 35.
- the strip element 34 runs in the longitudinal direction 28, thus extending in the direction of the edge 36.
- the strip element 34 equipped with a coating 33 can, for example, be a sandpaper glued to the underside 30 of the section 19 or 20.
- the strip element 34 provided on the underside of each section 19 or 20 essentially has two advantages. Firstly, it provides anti-slip properties and secondly, it compensates for tolerances in the height direction.
- each positioning aid 18 is provided on its underside 30 with an anti-slip coating 33, which in the embodiment shown is provided by a strip element 34.
- this coating 33 ensures that the positioning aid 18 rests on the row 10 of AGM batteries underneath in a slip-resistant manner, and the risk of a relative movement between the positioning aid 18 and the row of AGM batteries 3 underneath when the positioning aid 18 is fitted with AGM batteries 3 is minimized. As a result, an overall vertical alignment of all AGM batteries 3 stacked on top of one another in the vertical direction 16 can be ensured.
- Each housing of a battery 3 held by the stacking aid 2 in the intended use case is conical due to the manufacturing process.
- Fig. 11 shows, using two batteries 3 as an example, that a positioning aid 18 follows a row 10 of batteries 3 in the vertical direction 16. This then serves to align a further row 10 of AG M batteries 3 in the vertical direction 16 with high accuracy and reliability.
- the two-part nature of a positioning aid 18 enables compliance with standardized pallet dimensions, so that both order picking and transport of the system 1 according to the invention in the disassembled state is simplified.
- the individual sections of a positioning aid 18 can be assembled in a simple manner and without tools, with both a force-fitting and a form-fitting connection being provided in the longitudinal direction of the positioning aid 18.
- the spacers 32 provided on the top side 31 of each positioning aid 18 simplify the insertion of batteries 3 into the stacking aid 2, since they serve as guide rails. Furthermore, the batteries 3 are prevented from slipping sideways and a permanent distance is maintained between the individual batteries 3, which allows air circulation for the purpose of cooling the batteries 3.
