Description

Technical area

[0001] The present disclosure relates to a tray or a storage or transport tray according to the preamble of claim 1. State of the art

[0002] It is common practice to place shock- and moisture-prone transport items, such as battery cells, in a cushioning insert made of foam or cardboard for transport and storage. This insert is located or can be placed in a resilient, sealed enclosure, such as a box or container. The insert allows multiple transport items to be spaced apart from each other and from the enclosure, allowing them to be transported in the same enclosure. If the insert is made of an elastic material, it can reduce peak loads, such as shocks or temperature changes, that act on the transport item. The enclosure, in turn, simplifies the handling and stacking of multiple transport items, provides shielding against water, moisture, and dirt, and protects against localized loads.However, such a functional separation with an insert and enclosure requires two or more packaging elements made of different materials and thus different manufacturing processes. Foamed materials are suitable for the insert, but are difficult to clean in the event of contamination.

[0003] A transport structure without the aforementioned functional separation is disclosed in CN 2 18 113 698 U. This discloses a stackable tray with a receiving area with several receptacles for one battery cell each on top, whereby the receiving area of ​​the tray is covered by an identical tray stacked above it. The one-piece design facilitates production, loading, and cleaning, but leads to a conflict of objectives in the material selection. A more elastic material, compared to a stiffer material, provides better protection against shock loads at the expense of handleability, protection against local load peaks, and potentially cleaning options. Shielding against water, moisture, and dirt is particularly difficult with elastic materials with high manufacturing tolerances.

[0004] Conventional transport structures are therefore either made up of several parts and are therefore complex to manufacture and use, or they are made in one piece and the choice of material requires a compromise between damping and strength. Summary of Revelation

[0005] It is therefore an object of the present disclosure to overcome or at least mitigate the disadvantages of the prior art and, in particular, to provide a tray which is both constructed in one piece and has sufficient damping and rigidity.

[0006] This object is achieved by a tray having the features of claim 1.

[0007] The present disclosure relates to a tray, in particular a storage and / or transport tray. The tray has a first receiving area open toward a tray top side. The first receiving area is preferably arranged centrally. The first receiving area further has at least one first receptacle for at least one transport object. The transport object is in particular a battery module. According to the disclosure, damping elements for dampening shocks are provided between a tray side wall and the first receiving area. These damping elements are provided at least in sections and surround the first receiving area, preferably completely in the circumferential direction. The damping elements are in particular formed integrally or in one piece with the tray.

[0008] The tray is preferably made of plastic and can be stackable. The tray has a substantially rectangular base. Damping in this context refers to the reduction of external loads on the transported object. This is achieved through a combination of spring action and damping, in the sense of dynamics, of surrounding elements.

[0009] According to the invention, the tray side wall surrounds the receiving area on one or more sides and represents the lateral closure of the tray there. The tray side wall surrounds the receiving area partially or completely, wherein the tray side wall is also designed as a single piece or multiple pieces, i.e., divided. The tray side wall is spaced apart from the receiving area in the normal direction. Damping elements are formed between the tray side wall and the receiving area. These connect the tray side wall and the receiving area. The tray side wall closes off the damping elements to the side. The tray side wall, damping elements, and receiving area are preferably made from a single piece and the same material.

[0010] This means that forces or impacts acting laterally on the tray side wall are absorbed by the damping elements and distributed over a large area in the receiving area. The distance between the tray side wall and the receiving area allows a limited elastic displacement of the tray side wall in the direction of the receiving area under load, without the tray side wall coming into contact with the receiving area and / or deforming it beyond an extent that would strain or endanger the object being transported. The length of a load path of the damping element between the tray side wall and the receiving area is at least as long as the distance between the two. Under load, compression and / or bending and / or torsion occur in the damping element. For the same load on the tray side wall, there is therefore a greater displacement of an outer side of the tray side wall than with a rigid coupling of the tray side wall to the receiving area.The greater displacement of the tray side wall is equivalent to a lower load on the transported object and therefore a greater damping of the external load.

[0011] In a lateral plan view, the tray side wall accounts for between 50% and 100%, preferably between 80% and 90%, in particular 83%, of the cross-sectional area of ​​the tray.

[0012] Advantageous further developments of the present disclosure are the subject of subclaims.

[0013] The damping elements are preferably designed as connecting webs or pairs of connecting webs in a circumferential gap between the tray side wall and the receiving area. The connecting webs can, in particular, be curved or angled.

[0014] The damping elements surrounding the receiving area can be enclosed by the surrounding tray side wall, which can represent an outer side wall / lateral border of the tray. This protects the transported object against external loads from all lateral directions, i.e., external loads acting on the tray side wall.

[0015] Curved or angled connecting webs can enable a displacement of the outer side of the tray side wall due to compression of the connecting web and bending about a bending axis. With increasing curvature or angulation of the connecting web and with its increasing length, a lever arm can increase and thus a bending moment, which causes an external load in the connecting web, can increase. This means that with increasing curvature or angulation and the length of the connecting web, the stiffness of the damping elements can decrease. In other words, such a design of the damping elements using the material of the receiving area and the tray side wall can bring about damping that corresponds to the damping of a continuous damping element whose material is more elastic than that of the receiving area and the tray side wall.In other words, in the present disclosure, for example, a foam damping element can be replaced by a damping element made in one piece from the material of the remaining tray through structural measures. The tray can thus be made in one piece from plastic using an injection molding process.

[0016] Preferably, adjacent connecting webs of a connecting web pair are angled in opposite directions. External loading of the connecting webs can lead to a twisting of the connecting web about the bending axis. If the connecting webs are twisted in the same direction, this can lead to a twisting of the tray side wall. By angling the connecting webs of a connecting web pair in opposite directions, the twisting of the connecting webs of a connecting web pair can occur in opposite directions, thus preventing a twisting of the tray side wall and additional loads. Alternating bending of the connecting webs is also possible.

[0017] According to a further optional aspect of the disclosure, the tray further comprises at least one second receiving area. This can preferably be arranged centrally and open toward the tray bottom. The second receiving area can comprise at least one second receptacle for at least one transport object. The transport object can, in particular, be a battery module. The tray top and bottom can be designed to complement each other, so that the tray bottom of the tray can be placed as a lid on the tray top of an identical or compatible tray.

[0018] This means that the tray can have a first receiving area on the top side of the tray and a second receiving area on the bottom side of the tray. The two receiving areas can each have at least one receptacle, whereby the number of receptacles as well as their position and base area of ​​the first and second receiving areas can be identical. This allows the transported object to be received in the first receptacle of the first receiving area and / or the second receptacle of the second receiving area.

[0019] The tray top can be inserted into the tray bottom and / or the tray bottom can be inserted into the tray top. For this purpose, stacking geometries such as stacking edges, stacking corners, or projections can be formed on the tray top and / or bottom. On the opposite side of the respective stacking geometry, a corresponding recess or depression can be formed into which the respective stacking geometry can be inserted. This allows identical or compatible trays to be stacked on top of one another. Stacking geometries can also prevent stacked trays from slipping. An additional lid that covers or closes the tray can thus be omitted or replaced with an identical tray.

[0020] The tray top and bottom of identical or compatible trays can be plugged into each other and / or snapped together.

[0021] Preferably, the at least one first and at least one second receptacles enclose the at least one transport object together. The enclosing can, in particular, be complete.

[0022] This means that the transport object is held partly by the first receptacle of the first receiving area and partly by the second receptacle of the second receiving area. If the size, in particular the depth, of the two receptacles together corresponds to the size of the transport object, the object can be completely enclosed by the two receptacles. A transport object held by the first receptacle of the first receiving area can protrude beyond the first receiving area depending on the depth of insertion into the second receptacle of the second receiving area. This allows the transport object to be easily removed from the first receiving area and still be enclosed by placing the identically constructed tray on top.

[0023] According to an optional aspect of the disclosure, the first and second receiving areas form at least one closed cavity when two identical or compatible trays are mounted. Alternatively or additionally, the at least one first and second receptacle can form at least one closed cavity.

[0024] This means that when two identical or compatible trays are placed on top of one another, the first and second receiving areas and / or their boundaries can contact one another in a ring-shaped manner and close off the hollow space composed of the first and second receiving areas. Likewise, when two identical or compatible trays are placed on top of one another, the at least one first and second receptacle and / or their boundaries can contact one another and close off the at least one hollow space composed of the at least one first and second receptacle. As a result, the at least one transport object, which is enclosed by the two trays when placed on top of one another, can be shielded, i.e. protected, from external influences such as dirt, water, moisture or the surrounding atmosphere.

[0025] The tray preferably has a single-walled intermediate floor that separates the first receiving area and the second receiving area from one another. The separation can be at least partial. This means that the first receiving area and the second receiving area can be adjacent to the intermediate floor. The intermediate floor can separate the first receiving area and the second receiving area of ​​the same tray from one another. Likewise, the intermediate floor can have interruptions and / or extend only along part of the tray. The first and second receiving areas of the same tray can be connected. This allows transport objects to be spaced apart and separated from one another and / or to communicate with one another.

[0026] It is furthermore advantageous if the first receiving area has a first compartment with a large number of first receptacles and the second receiving area has a second compartment with a large number of second receptacles. This means that the upper side of the tray and the lower side of the tray can have at least one intermediate and / or separating wall in the longitudinal and / or transverse direction, which at least partially separates the first and / or second receptacles from one another. This means that a plurality of transport objects can be received by the tray without them coming into contact with one another and / or becoming damaged and / or slipping. The first and second receptacles can be of the same size. This means that in particular the base area of ​​the first and second receptacles can be of the same size. This enables in particular the transport of cylindrical or prism-shaped transport objects. The first and second receptacles can be aligned with one another when two trays are placed on top of one another. This means thatThe at least one first receptacle and the at least one second receptacle can be located opposite each other, particularly vertically. This allows cylindrical or prism-shaped transport objects, in particular, to be accommodated when two trays are stacked on top of each other.

[0027] Preferably, an upper side of the first receiving area and / or the first compartment and an underside of the second receiving area and / or the second compartment of two identical or compatible trays contact each other when placed on top. This preferably enables a force connection in the vertical direction, in particular for the weight forces of trays resting on them. This means that an edge of the receiving area and / or the compartments can bear the load of trays lying above. This can relieve the load on the transported objects or prevent stress on the transported objects. Furthermore, deformation or bending of the trays, in particular in their center, can be prevented, or the wall thickness and rigidity of the tray can be reduced.

[0028] According to an optional aspect of the disclosure, a border that at least partially or completely surrounds the first receiving area projects beyond the first compartment. The border can extend into a recess and / or bulge on an underside of an outer border of the second receiving area of ​​a second tray placed above it. This means that the border of the first receiving area can project beyond the first compartment, i.e., can end above it. Opposite ends of the border of the first receiving area and the outer border of the second receiving area, i.e., an upper side of the border of the first receiving area and the underside of the outer border of the second receiving area, can be complementarily designed. As a result, the borders can engage with one another when the trays are placed on top of one another, form a tight seal, and prevent lateral movement or slippage of the trays relative to one another.

[0029] Preferably, the outer border of the second receiving area can project laterally, ie outwards, beyond the border which at least partially surrounds or completely closes off the first receiving area.

[0030] This allows dirt and / or water coming from the sides and / or above to be diverted away from the receiving areas.

[0031] It is furthermore advantageous that spring or clamping elements which are formed integrally or from a single material are provided in the first and / or second receptacles for non-positively fixing the transport objects in the receptacles. The spring or clamping elements can in particular be provided laterally. This means that the compartments and / or walls of the receptacles can have spring or clamping elements. These can in particular taper along the vertical direction starting from the base. This makes it easier to insert the transport object. The spring or clamping elements can extend perpendicular to the wall from which they originate. By spacing the transport objects from one another, a gripper or manipulator can remove them from the tray and / or place them in the tray. This enables automated handling of the transport objects.

[0032] Preferably, an upper edge of the first receiving area projects beyond the tray side wall, and a lower edge of the second receiving area is flush with the tray side wall. This means that the upper edge of the first receiving area can project beyond the tray side wall and thus can be formed above it. The lower edge of the second receiving area can be formed at the same height as the tray side wall and thus can lie in a plane with a lower edge of the tray side wall. In other words, the tray side wall can be shorter in height than the height of the tray. This can result in a gap between two tray side walls when the trays are in place, which gap can be accessed manually or using a gripper to lift one or more trays. Likewise, a tray can be placed on top of another tray.The distance can also ensure that there is no double fit and that the edges tightly seal the enclosed receiving areas when two trays are placed on top of each other.

[0033] It is further advantageous for a floor of the first receiving area and a ceiling of the second receiving area to be recessed relative to the tray side wall. This allows the tray side wall to protect and / or at least partially cover transport items received in the receiving areas.

[0034] Preferably, the tray top and / or bottom have stacking geometries. These can, in particular, represent, at least in sections, circumferential stacking edges and / or stacking corners. This allows the trays to be secured against lateral slippage when placed in the tray's position and / or to be guided and centered during placement.

[0035] According to an optional aspect of the disclosure, handling elements for automated gripping using a gripper or manipulator are formed on the tray top and / or bottom. The handling elements can be arranged such that they can be reached by the gripper or manipulator even when the tray is filled. This allows the tray to be lifted from a stack, pallet, conveyor belt, or storage location and manipulated, i.e., moved or placed at an aforementioned location. This enables automated handling of the tray and / or the transported items.

[0036] According to a further optional aspect of the disclosure, the tray is in particular a storage and / or transport tray, preferably made of plastic, with at least one first receiving area, preferably arranged centrally and open towards a tray top, having at least one first receptacle for at least one transport object, in particular a battery module; at least one second receiving area, preferably arranged centrally and open towards the tray bottom, having at least one second receptacle for at least one transport object, in particular a battery module, wherein the tray top and the tray bottom are designed to be complementary, so that the tray bottom of the tray can be placed as a lid on a tray top of an identical or compatible tray.

[0037] It is further advantageous that the at least one first and the at least one second receptacle enclose the at least one transport object together, in particular completely.

[0038] It is further advantageous that the first and second receiving areas and / or the at least one first and second receptacle form at least one closed cavity when two identical or compatible trays are placed on top.

[0039] Preferably, the tray further comprises a single-walled intermediate base which at least partially separates the first receiving area and the second receiving area from one another.

[0040] It is furthermore advantageous that the first receiving area has a first compartment with a plurality of first receptacles, preferably of equal size, and the second receiving area has a second compartment with a plurality of second receptacles, preferably of equal size, wherein the first and second receptacles are aligned with one another when two trays are placed on top of one another.

[0041] It is furthermore advantageous that an upper side of the first receiving area and / or of the first compartment, and an underside of the second receiving area and / or of the second compartment, of two identical or compatible trays contact each other in the mounted state, and preferably enable a force connection in the vertical direction, in particular for weight forces of trays resting on them.

[0042] It is further advantageous that a border which at least partially surrounds or completely encloses the first receiving area projects relative to the first compartment and can dip into a depression and / or bulge on an underside of an outer border of the second receiving area of ​​a second tray placed above it.

[0043] It is furthermore advantageous that spring or clamping elements formed integrally or in one piece from the material are provided in the first and / or second receptacles, in particular laterally, for the non-positive fixing of the transport objects in the receptacles.

[0044] It is further advantageous that an upper edge of the first receiving area projects beyond the tray side wall and a lower edge of the second receiving area is flush with the tray side wall.

[0045] It is further advantageous that a bottom of the first receiving area and a ceiling of the second receiving area are recessed relative to the tray side wall.

[0046] It is further advantageous that the tray top and / or the tray bottom have stacking geometries, in particular, at least in sections, circumferential stacking edges and / or stacking corners.

[0047] It is further advantageous that handling elements for automated gripping by means of a gripper or manipulator are formed on the tray top and / or the tray bottom. Short description of the characters

Detailed description of the characters

[0049] Fig. 1 shows a tray 2 according to the disclosure. The tray 2 has a substantially rectangular base area. A first receiving area 6 with a plurality of first receptacles 8 is formed on a tray top 4. A circumferential tray side wall 10 forms the lateral end of the tray 2. This is spaced apart from a border 12, which laterally surrounds a first receiving area 6. A plurality of connecting webs 14 are formed between the tray side wall 10 and the receiving area 6.

[0050] The first receptacles 8 have a rectangular base area. Within the first receptacle area 6, the first receptacles 8 are separated from one another by longitudinal and transverse walls, which form a first compartment 16. The longitudinal and transverse walls run parallel to the long and short sides of the tray side wall 10. Within each first receptacle 8, two clamping elements 18 are formed on each of its long sides and one clamping element 18 is formed on each of its short sides, which extend from the first compartment 16 and the border 12 into the first receptacles 8.

[0051] The connecting webs 14 extend in a height direction H and are angled about an axis parallel to the height direction H. Adjacent connecting webs 14 are angled in the opposite direction.

[0052] Fig. 2 shows a side view of the tray 2. In the direction of the tray top 4, the (closed) border 12 protrudes beyond the (closed) tray side wall 10. The tray side wall 10 protrudes equally beyond the border 12 on both sides.

[0053] Fig. 3 shows a plan view of the tray 2 with the first receiving area 6 with a plurality of first receptacles 8, which are separated from one another by longitudinal and transverse walls and are altogether enclosed by the border 12, as well as the circumferential tray side wall 10 which is spaced therefrom and which is connected to the border 12 of the receiving area 6 by means of the connecting webs 14, as well as a section line "VV".

[0054] The distance between the tray side wall 10 and the border 12 is smaller on the long side of the tray 2 than on the short side of the tray 2. The connecting webs 14 have a V-shaped contour in plan view. This means that the connecting webs 14 each have two straight or only slightly curved sections 22 that are at an angle to one another and merge into one another. One side of the connecting web 14 has an obtuse angle and another side has an acute angle. Two adjacent connecting webs 14 each face one another with their obtuse-angled sides or with their acute-angled sides. The clamping elements 18 of the receptacles 8 are formed orthogonally to the longitudinal, transverse wall or the border 12, from which they extend into the receptacle 8. Four handling elements 24 are formed between the receptacles 8, which handling elements have an engagement with two undercuts.A gripper can engage in the handling elements 24, engage behind the undercuts, and manipulate the tray 2. Several passages 28, which serve as drainage openings when cleaning the tray, are formed in the base 26 of the receptacles 8.

[0055] Fig. 4 shows a section of the first receiving area 6 with a plurality of receptacles 8, which are enclosed by the border 12 and are connected to the tray side wall 10 via connecting webs 14. The connecting webs 14 adjoin the tray side wall 10 and the border 12 orthogonally, with a curve being formed in direct connection in each case, to which the straight or only slightly curved section 22 adjoins, which extends at an angle to the tray side wall 10 or the border 12. Starting from the tray side wall 10 and the lower border 12, the two sections 22 of a connecting web 14 extend towards one another at an angle and merge into one another centrally between the tray side wall 10 and the border 12, forming a curve 30. The wall thickness of the connecting web 14 is constant over the length from the tray side wall 10 to the border 12.The connecting webs 14 on the long side of the tray 2 are narrower than those on the short side of the tray 2 due to the smaller distance between the tray side wall 10 and the border 12. For this reason, the sections 22 of the connecting web 14 on the long side of the tray 2 are shorter than those of the connecting webs 14 on the short side of the tray 2. The distance, in the circumferential direction, between two connecting webs 14, which are opposite one another with their acute-angled sides, is greater than the length of their sections 22.As a result, the tray side wall 10 can be pressed by a load in the direction of the border 12 until the tray side wall 10 rests on the outer section 22, which itself rests on the inner section 22, which itself rests on the border 12; or until the tray side wall 10 rests on the curve 30 of the connecting web 14, which itself rests on the border 12; or until the tray side wall 10 rests directly on the border 12 without two adjacent connecting webs 14 contacting each other and blocking the displacement of the tray side wall 10.

[0056] Fig. 5 shows a sectional view of tray 2 along the cutting line "VV" in Fig. 3 . On the tray top side 4, the first receiving area 6 is formed with the first receptacles 8, which are separated from one another by longitudinal and transverse walls that form the first compartment 16. On the tray bottom side 32, a second receiving area 34 is formed with second receptacles 36, which are separated from one another by longitudinal and transverse walls that form a second compartment 38. The first compartment 16 and the second compartment 38 lie opposite one another and are aligned with one another. The first receiving area 6 and the second receiving area 34 are separated from one another by an intermediate floor 40. The border 12 of the first receiving area 6 projects above the tray side wall 10 in the vertical direction H. An upper edge 42 of the first receiving area 6 lies within the border 12 and below its upper end. The upper edge 42 lies above an upper end of the tray side wall 10.A lower edge 44 of the second receiving area 34 ends flush with the tray side wall 10. Starting from the first compartment 16 and the second compartment 38, the clamping elements 18 project into the first receptacles 8 and the second receptacles 36. The clamping elements 18 are arcuate, with the clamping elements 18 projecting less deeply into the first receptacles 8 and the second receptacles 36 as the distance from the intermediate floor 40 increases. The intermediate floor 40 forms a floor 26 for the first receptacles 8 and a ceiling 46 for the second receptacles 36.

[0057] Fig. 6 shows the tray 2 above an identical tray 102 in the position in which the tray 2 can be stacked on the tray 102.

[0058] Fig. 7 shows tray 2 stacked on the identically constructed tray 102. The tray side walls 10 are aligned with each other. The tray side wall 10 of tray 2 and the tray side wall 10 of the identically constructed tray 102 are spaced apart from each other in the vertical direction H.

[0059] Fig. 8 shows a side view of tray 2, which is stacked on the identically constructed tray 102. The tray side walls 10 are spaced apart from each other in the vertical direction H. This distance is less than the projection of the border 12 above the tray side wall 10 in the vertical direction H. The trays 2, 102 are thus immersed in each other.

[0060] Fig. 9 shows a top view of tray 2 on the identically constructed tray 102 and a section line "XX. The two trays 2, 102 are aligned with each other. The identically constructed tray 102 is therefore completely hidden in the top view by the tray 2 above it.

[0061] Fig. 10 shows a sectional view of tray 2 along the cutting line "XX" in Fig. 10 which is stacked on the identically constructed tray 102. The second receiving area 34 of the tray 2 and its second receptacles 36 are aligned with the first receiving area 6 of the identically constructed tray 102 and its first receptacles 8. This means that the second compartment 38 of the tray 2 is aligned with the first compartment 16 of the identically constructed tray 102 and rests flush thereon. The second receptacles 36 of the tray 2 and the first receptacles 8 of the identically constructed tray 102 together each form a closed cavity 48.

[0062] Fig. 11 shows a section of the sectional view of the tray 2, which is placed on a structurally identical tray 102. An outer border 50 surrounding the second receptacles 36 has a bulge 52 at its lower end, wherein the outer border 50 has a laterally outward offset, i.e. towards the tray side wall 10. Within the bulge 52, the border 12 of the structurally identical tray 102 dips into the tray 2. For this purpose, a circumferential recess 54 is formed in the second compartment 38. The bulge 52 of the outer border 50 and the recess 54 of the second compartment 38 as well as the upper end of the border 12 thus form a stacking geometry 56 which prevents the tray 2 from slipping on the structurally identical tray 102.

[0063] Fig. 12 shows the tray 2 with a plurality of battery modules 58, each of which is accommodated in a first receptacle 8. The battery modules 58 are essentially cuboid-shaped and protrude beyond the first receptacle area 6 and the border 12. The battery modules 58 are spaced apart from each other and from the first compartment 16 by means of the clamping elements 18.

[0064] Fign. 13 und 14 show a top view of the tray 2 with the battery modules 58. The clamping elements 18 contact the battery modules 58 from four sides and fix them in the first receptacles 8. The clamping elements 18 space the battery modules 58 from one another and from the border 12, to which the tray side wall 10 is connected via the connecting webs 14. The handling elements 24 are located within easy reach between the battery modules 58. The battery modules 58 stand on the base 26. The passage 28 of the base 26 in the middle of a longer side of the first receptacle 8 is wider than the battery module 58 and is therefore only partially covered by it.

[0065] Fig. 15 shows a side view of tray 2 with the battery modules 58.

[0066] Fig. 16 shows the tray 2 above the battery modules 58 above an identical tray 102 in a position in which the battery modules 58 are aligned with the concealed second receptacles 36 of the tray 2 and the first receptacles 8 of the identical tray 102, and the tray 2 is flush with the identical tray 102. This means that from this position, by moving the tray 2, the battery modules 58, and the identical tray 102 toward each other, the battery modules 58 can be received and enclosed by them.

[0067] Fig. 17 shows a top view of the tray 2, which rests on the concealed identical tray 102 and which together accommodate battery modules 58, as well as a section line "XVIII-XVIII".

[0068] Fig. 18 shows a sectional view of tray 2 along the section line "XVIII-XVIII" in Fig. 17 on the identical tray 102, wherein the second receptacles 36 of the tray 2 and the first receptacles 8 of the identical tray 102 receive and enclose battery modules 58.
