Definitions

  • the present invention relates to a stackable crate for receiving and transporting objects and for stacking on top of one another in a stacking direction with at least one other crate of the same type, the crate comprising a base and a protruding from the base and at least partially, in particular completely, around the base has circumferential side wall, the bottom and the side wall together delimiting a receiving space of the box for receiving the objects and the side wall in a plan view of the box has a, in particular rectangular, basic shape with, in particular four, corner areas and side wall sections running between the corner areas, wherein the side wall sections running between the corner areas are each delimited by an upper side of the side wall section inclined at least in regions obliquely to the stacking direction and an underside of the side wall section arranged opposite thereto.
  • Boxes of this type are, for example, in the EP 1 287 780 B1 shown.
  • the boxes stacked one on top of the other are each set down in their corner areas.
  • the top sides of the side wall sections between the corner areas are inclined to the stacking direction. This has the advantage that water and / or other liquids or moisture run off the inclined upper sides of the side wall sections following the slope, and the upper sides of the side wall sections dry faster. This is particularly advantageous if the boxes are used in a washing and / or rinsing process.
  • a disadvantage of the construction according to the EP 1 287 780 B1 is that the maximum possible load of such boxes is limited.
  • the object of the invention is therefore to improve generic stackable boxes so that on the one hand they have side walls that dry as quickly as possible, but on the other hand they also enable high payloads.
  • the invention proposes that on the side wall sections on the upper sides of the side wall sections in each case adjacent to at least one region of the respective upper side which is inclined obliquely to the stacking direction, preferably between two of these obliquely inclined regions of the respective upper side, above this or these at an angle inclined area (s) protruding contact surfaces and / or on the undersides of the side wall sections over at least one area adjacent thereto, preferably two adjacent areas, protruding contact areas on the respective underside.
  • the areas of the upper side of the side wall sections remaining between the contact surfaces are inclined at an angle to the stacking direction, so that water and other liquids flow away rapidly from the upper sides of the side wall sections and thus promote rapid drying of the side wall sections.
  • the contact surfaces projecting beyond the respective adjacent areas can be attached to both the upper sides and the lower sides of the side wall sections.
  • the undersides of the side wall sections of the respective upper box lie exclusively in the area of the contact surfaces on the upper sides of the side wall sections of the respective lower box. This advantageously results from the fact that the regions of the respective upper sides of the respective upper sides which are inclined to the stacking direction Sidewall sections of the lower box are spaced from the regions of the undersides of the sidewall sections of the respective upper box arranged above. This creates an air gap between the respective upper sides of the side wall sections of the respective lower box and the lower sides of the side wall sections of the respective upper box, which in turn promotes the rapid drying of the side walls. It is also advantageously provided that the boxes stacked one on top of the other do not touch in the corner areas. This is achieved in that the contact areas also protrude beyond the corner areas of the side wall of the box.
  • Stackable boxes according to the invention could also be referred to as transport and / or storage boxes or generally as containers or transport containers. Even if they are designed for mechanical gripping by means of at least one gripping device, they can of course also be conveniently gripped and transported by hand.
  • mechanical gripping is to be understood to mean that a crate is contacted physically by means of a gripping device in such a way that it is raised with the gripping devices in the machine-gripped, that is to say in other words machine-contacted or machine-handled, state , transported or moved in any other way.
  • Stackable boxes according to the invention can be used in very different areas. In principle, it is conceivable to use such stackable boxes for storing, washing and transporting dishes, glasses and the like. Such machine-accessible stackable boxes are particularly preferably used in the industrial environment, in order to store, transport, wash and similar objects which are to be processed, manufactured or manufactured in industry.
  • the minimum load capacity of stackable boxes according to the invention is advantageously at least 10 kg, particularly preferably 25 kg per box.
  • Stackable boxes according to the invention can also be dimensioned very differently. These are preferably boxes with a rectangular or square basic shape.
  • the length of the box is advantageously in the range from 10 cm to 120 cm, preferably from 25 cm to 65 cm, and its width in the range from 10 cm to 100 cm, preferably 25 cm to 45 cm.
  • the height of the box is in the range from 3 cm to 25 cm, preferably from 4 cm to 15 cm.
  • Crates according to the invention can consist of different materials or material compositions. It can be metal boxes but also plastic boxes. Even wooden or composite boxes are conceivable. In any case, it is preferably provided that the stackable box is formed in one piece. This then also means that the side wall and the base are then connected to one another in one piece and consist of the same material.
  • the boxes according to the invention can be made of a suitable plastic, e.g. Trade polypropylene (PP), polyamide (PA), polyoxymethylene (POM) or polybutylene terephthalate (PBT). Boxes according to the invention can e.g. are manufactured by injection molding.
  • Boxes according to the invention have a bottom which delimits the receiving space of the box, into which the objects can be placed, together with the peripheral side wall.
  • the box with the floor is usually placed on the ground so that the objects in the recording room lie on the floor.
  • the floor therefore usually forms the support surface for the objects in the receiving space of the box.
  • the receiving space is delimited by the peripheral side wall of the box.
  • the side wall when closed, can completely surround the floor. But it can also be made of several components that are interrupted. Even then it can still be a peripheral side wall. Both the side wall and the bottom can be designed as self-contained surfaces.
  • the circumferential side wall is composed of corner areas and, preferably straight, side wall sections running between the corner areas.
  • the side wall can have a rectangular basic shape in a plan view of the box.
  • the term rectangular is not only to be understood in the strict mathematical sense. It also includes configurations in which the side wall sections in principle converge at a right angle in the corner area, but the corner area itself nevertheless has roundings and the like, etc.
  • boxes according to the invention are designed such that they can be stacked on top of one another together with other boxes of the same type in a stacking direction.
  • the stacking direction is generally predetermined by the shape of the box or its base and its side wall. E.g. the floor can protrude beyond the side wall, so that this protruding area of the bottom of a box can be placed in the upper area of the receiving space of the box below it, i.e. in the area which is surrounded by the side wall, so that the bottom of the upper box faces the Sides is held positively from the side wall of the lower box.
  • This also automatically results in the corresponding stacking direction in which the boxes must be stacked on top of one another.
  • the features according to the invention must be implemented with respect to at least one stacking direction so that it is a box according to the invention.
  • the bottom forms an upper, in particular flat, boundary surface with which it delimits the receiving space.
  • the stacking direction is then advantageously normal to this upper boundary surface of the floor.
  • the stacking direction then forms a surface normal to this upper boundary surface of the floor.
  • the upper boundary surface of the floor limits the receiving space of the box downwards, while the side wall limits the receiving space in this position of the box to the sides, that is to say in horizontal directions.
  • the boundary surface is spanned from the top of the floor. This also applies if the base is lattice-shaped or the like.
  • the upper, in particular flat, boundary surface is the surface on which, in the operating position, the objects stored in the box in the receiving space lie.
  • the stacking direction is used here as a reference direction at several points.
  • the above-mentioned, in particular flat, boundary surface of the floor could also be used as a geometric reference, it then having to be assumed that the stacking direction forms a surface normal to this upper boundary surface of the floor, i.e. orthogonally on all sides on the upper boundary surface of the floor stands.
  • Crates according to the invention can be open at the top, that is to say on the side of the side wall facing away from the floor. In other words, such boxes have an upwardly open receiving space.
  • stackable boxes according to the invention can of course also be closed with a lid on the side of the receiving space opposite the floor by attaching a corresponding lid on this side of a side wall.
  • FIGS 1 to 19 The first exemplary embodiment of the invention, which is shown in FIGS 1 to 19 is shown. The following description of the further exemplary embodiments then focuses on the differences from the first exemplary embodiment.
  • the inventive box 1 of the first embodiment is in the 1 to 11 stacked in the stacking direction 2 on another box 1 according to the invention of the same type.
  • the Fig. 12-19 show this box 1 of the first embodiment individually or partial areas thereof.
  • the crate 1 has a base 3 and a side wall 4 which projects beyond the base 3 parallel to the stacking direction 2 and in this exemplary embodiment is completely formed around the base 3.
  • the bottom 3 and the side wall 4 together delimit the receiving space 5 of the box 1, which is provided for receiving the objects in the box.
  • the receiving space 5 is bounded downwards by an upper, here flat boundary surface 17 of the bottom 3.
  • the stacking direction 2 forms a surface normal to this upper boundary surface 17 of the bottom 3. In other words, the stacking direction 2 is normal to the upper boundary surface 17 of the bottom 3.
  • the stacking direction 2 is also predetermined in this exemplary embodiment in that the bottom is used to stack the boxes 1 on top of one another 3 of the respective upper box 1 must be inserted into the upper area of the receiving space 5 of the lower box 1 surrounded by the side wall 4. Like this for example in Fig. 2 is clearly visible, this results in a form fit in the direction orthogonal to the stacking direction 2. This has the consequence that the boxes 1 must be stacked on top of each other in the stacking direction 2 and for stacking the respective upper box or Boxes 1 against the stacking direction 2 must be lifted from the lower box or boxes 1.
  • both the bottom 3 and the side wall 4 can be designed as self-contained surfaces. This is not the case in this embodiment.
  • both the bottom 3 and the side walls 4 each have openings or openings.
  • the base 3 is formed by a lattice-shaped structure.
  • the side wall 4 has a multiplicity of window-like openings. All of this is of course only shown by way of example and can also be carried out in other ways known per se. Above all, as far as necessary for the intended application, reinforcing ribs and the like can be formed both on the bottom 3 and on the side wall 4.
  • the boxes 1 shown here have a rectangular basic shape with four corner regions 16 which are rounded in this exemplary embodiment. In each case, side wall sections 21 run between corner regions 16.
  • side wall 4 which runs completely around floor 3, is thus formed from four corner regions 16 and the preferably straight side wall sections 21 running between them.
  • boxes 1 according to the invention are also conceivable and possible with a basic shape that is not rectangular, but differently designed.
  • the preferred side wall sections 21 realized here are each straight or linear. They meet an adjacent side wall section 21 at an orthogonal angle in the corner regions 16. Of course, this does not have to be the case either.
  • the number of corner regions 16 and the number and shape of the side wall sections 21 can of course also be designed differently.
  • the boxes 1 are designed with spaced apart adapters for mechanical gripping of the box 1 by means of at least one gripping device 6.

  • Fig. 6 shows the section along the section line DD Fig. 4 through the side wall sections 21 of the boxes 1 stacked on top of one another and thus in an area outside the contact surfaces 25.
  • Fig. 7 shows the section along the section line EE Fig. 4 and thus the area in which the contact surfaces 25 of the respective lower box 1 formed on the respective upper side 22 of the side wall section 21 support the lower sides 23 of the box 1 arranged above.
  • the section shown is the spaced arrangement of the underside 23 of the respective upper box 1 from the inclined region 24 of the Top side 22 of the side wall section 21 of the lower box 1 can be seen clearly. An air gap thus arises between the respective underside 23 and the inclined region 24 of the respective upper side 22.
  • the top sides 22 of the side wall sections 21 of the respective box 1 can dry particularly quickly and well.
  • the term oblique in the description of the invention is to be understood to mean that it is an angle, preferably an acute angle, which is neither a right angle nor coincides with a parallel.
  • the areas 24 of the respective top side 22 of the respective side wall section 21 which are inclined to the stacking direction 2 preferably form an acute angle with the stacking direction in a range from 5 ° to 15 °, preferably from 7 ° to 10 °, a.
  • the contact surfaces 25 and 27 are the only areas of the entire side wall 4, in which the stacked boxes 1 are supported on one another. This means that, in preferred embodiments, the boxes 1 stacked on top of one another do not touch in the corner regions 16 and are therefore not supported on one another in these corner regions 16.
  • the contact surfaces 25 in a first plane 28 are arranged and the respective adjacent areas 24 of the respective upper sides 22 are arranged in a second plane 29, the first plane 28 and the second plane 29 enclosing an acute angle 30 with one another.
  • the in Fig. 7 drawn in first plane 28 of the contact surface 25 in Fig. 6 entered again.
  • the contact surfaces 25 formed on the upper sides 22 run in a plane 31 arranged normal to the stacking direction 2.
  • Fig. 27 shows a section in an area in which there is no contact surface 27.
  • the oblique regions 24 of the respective upper side 22 of the side wall sections 21 of the respective lower box 1 are spaced apart from the respective lower sides 23 of the side wall sections 21 of the box 1 stacked above them
  • Fig. 27 clearly visible air gap in turn promotes drying of the top and bottom sides of the side wall sections.
  • FIG. 28 one can see a section through the side wall sections 21 of the boxes 1 stacked on top of one another in the area of the contact surfaces 27 formed on the respective undersides 23 of the side wall sections 21. That these protrude beyond the respectively adjacent areas 26 is shown in FIG Fig. 26 good to see.
  • the contact surfaces 27 are arranged in a first plane 28 and the regions 26 of the undersides 23 of the respective underside 23 which are adjacent thereto are arranged in a second plane 29, the first plane 28 and the second plane 29 form an acute angle 30 with one another.
  • the first level 28 is again off Fig. 28 also in Fig. 27 registered. This embodiment shows in particular in Fig.
  • the contact surfaces 27 formed on the undersides 23 in a plane 32 arranged obliquely to the stacking direction 2 can run.
  • This oblique course of the contact surfaces 27 is favorable, as in FIG Fig. 28 also shown, formed at an angle which corresponds to the inclined regions 26 of the respective upper sides 22 of the side wall sections 21.
  • the contact surfaces 27 lie snugly and over their entire surface on the corresponding areas 26 of the upper sides 22 of the box 1 arranged underneath, so that the boxes 1 stacked one on top of the other are stably supported.
  • This embodiment according to the 25 to 28 also shows, by way of example, that in the case in which the contact surfaces 27 projecting beyond the respectively adjacent regions 26 of the underside 23 are formed on the underside 23, the regions 26 of the underside 23 respectively adjacent to the contact surfaces 27 can run in a plane 33, on which the stacking direction 2 is arranged normally, see in particular Fig. 27 .
  • FIG. 27 shows analog to Fig. 6 again the situation in a section through the side walls 21 of the stacked boxes 1 outside the areas of the contact surfaces 25 and 27. In these areas, the spaced arrangement and thus the drying gap between the undersides 23 of the respective upper box 1 and the obliquely inclined regions 24 on the upper sides 22 of the side wall sections 21 of the box 1 arranged underneath.
  • the angle 30 between the first plane 28 and the second plane 29 results, as in FIG Fig. 29 shown, again the same as in the other two previously described embodiments.
  • the sizes of the contact surfaces 25 and 27 and their relationship to the remaining surfaces of the upper sides 22 and lower sides 23 of the side wall sections 21 can in principle be set accordingly in accordance with the load requirements to be expected or achieved. However, it is favorable if a ratio between the sum of the areas of all contact surfaces 25 on the top sides 22 of all side wall sections 21 of box 1 on the one hand and the total area of the top sides of side wall 4 of box 1 on the other hand is in a range from 1: 5 to 1:15, preferably 1: 9 to 1:11. The same applies expediently if the contact surfaces 27 are arranged on the undersides 23 of the side walls 4.
  • a ratio between the sum of the areas of all contact surfaces 27 on the undersides 23 of all the side wall sections 21 of the box 1 on the one hand and the total area of the undersides 23 of the side wall 4 of the box 1 on the other hand in a range from 1: 5 to 1: 15, preferably from 1: 9 to 1:11.
  • the respective contact surface 25 or 27 has an area in the range from 75 mm 2 to 175 mm 2 , preferably from 120 mm 2 to 135 mm 2 .
  • a ratio between the sum of the surfaces of all the contact surfaces 25 and 27 on the top sides 22 and / or the undersides 23 of all side wall sections 21 of the box 1 on the one hand and the total area of the upper boundary surface 17 of the bottom 3 of the box 1 on the other hand is in a range from 1: 100 to 1: 130, preferably from 1: 110 to 1: 115.
