DETAILED DESCRIPTION

[0028] In a first aspect, the invention concerns a storage device 12 and an apparatus 10 for storing individual parts, in particular flat parts such as stamped parts. A first embodiment of a storage device is shown in FIG. 1. The storage device 12 comprises a floor 20 on which the parts are placed and a partitioning structure 30 which divides the interior of the storage device 12 into juxtaposed compartments or pockets 32 which can be filled from the top. In this regard, internal delimiting elements 36 are provided which are configured as webs or wall elements in the embodiment shown. The compartments 32, which in particular are cuboid in shape, are open at the top and are delimited at the bottom by the floor 20. Furthermore, the storage device 12 comprises an external delimiting structure which is formed by external delimiting walls 42 (side walls). Below the floor 20 of the compartments 32 is a lower floor element 14 or base element which can be provided for positioning on a substrate. The floor element 14 comprises at least one opening 16 through which the floor 20 can be contacted from below; this can also be described as a floor plate, perforated plate or base plate. Preferably, a plurality of openings 16 are distributed over the floor element 14.

[0029] The storage device 12, which may also be described as a cassette part, is designed to accommodate flat parts or shaped parts with a small clearance with respect to the delimiting elements 36 (cassette walls). In order to pick them up more quickly and/or to load them more easily, the floor 20 is disposed so that its height can be adjusted within a frame structure of the storage device 12 formed by the delimiting elements 36 and/or delimiting walls 42, as indicated by the arrow 2 in FIG. 1. The floor 20 can be moved between a lower position, in which it is approximately flush with a lower end of the storage device 12, and an upper position essentially at the upper edge of the storage device 12. FIG. 1 shows the floor 20 in a partially raised position. A lifting device 60 (FIG. 3) may be used to displace it; the device can optionally be disposed below or next to the storage device 12. The lifting device may have at least one lifting element 62 which can make contact with the lifting floor 20 from below or laterally through one of the openings 16 in the fixed floor element 14. Slots 24 are formed in the floor 20; their shape preferably matches the base area of the delimiting elements 36 of the grid-like partitioning structure 30. There is preferably a gap between the movable floor 20 and the walls of the storage device 12 which depends on the precision of the lifting system.

[0030] Naturally, the above description is also applicable to the opposite case, i.e. where the delimiting elements 36 and/or delimiting walls 42 are disposed on or between the floor 20 or floor sections (21, 22, see FIG. 2) in a height-adjustable manner.

[0031] The partitioning structure 30 has a grid-like frame 34 at its upper end which increases the stability but is optional. The delimiting elements 36 and the outer delimiting walls 42 are formed by the individual webs or wall elements which extend between an underside of the storage device 12 and the frame 34. Openings 38 are formed between individual compartments 32 in the delimiting elements 36 of the grid-like partitioning structure 30. The openings 38 extend essentially over the whole maximum loading depth of the compartments 32 or along the entire displacement path of the floor 20. The outer delimiting walls 42 are also provided with openings 44 so that each individual compartment 32 can be accessed from the side. The floor element 14, the outer delimiting walls 42 and the partitioning structure 30 form a fixed, preferably grid-like body. The storage device 12 may essentially be produced from wood. The frame 34 may be formed from metal.

[0032] The apertures or openings 38 in the delimiting elements 36 essentially have two functions. Firstly, they allow for there to be an associated lifting plate, or an associated floor 20 so that the floor 20 can be moved with one or only a few jacks or lifting elements 62 of an external lifting device 60. Secondly, loading and/or picking up parts can easily be carried out manually, for example if the lifting system fails, because each compartment 32 is accessible from all sides.

[0033] FIG. 2 shows a further storage device with a floor 20 which comprises several separately height-adjustable floor sections 21, 22. The floor sections 21, 22 here may each form the floor region of one or more individual compartments 32. Thus, possibly as a function of the size of the parts to be stacked, a separate floor plate is provided for each stack row or group of stack rows. This means that only one stack row or a group of stack rows in a container can be lowered or lifted simultaneously. The number of separate floor sections 21, 22 to be moved may correspond to the number of compartments 32, so that each compartment 32 can be individually loaded or emptied. Apart from this, the embodiment of FIG. 2 is the same as that of FIG. 1.

[0034] The number of jacks or lifting elements 62 advantageously is adapted to the number of lifting floors or floor sections 21, 22 in a manner such that tilting is prevented. To this end (as is also the case for the first embodiment of FIG. 1), a coupling frame may also be used which connects individual or several floor sections 21, 22 with the lifting device 60. In a preferred embodiment, the lifting device 60 may have at least one horizontally and/or vertically displaceable lifting element 62 in order to be able to select different floor sections 21, 22 to be lifted. The lifting element 62 may in this regard be mounted on a track system, for example. In this manner, the floor sections 21, 22 may be actuated separately without a respective dedicated lifting device 60 being required for each one.

[0035] The storage device 12 forms an insert to place in a base rack 50 shown in FIG. 3. The storage device 12 then preferably forms an independent unit which can be removably mounted in a base rack 50 so that it can be replaced separately in the event of damage.

[0036] The base rack 50 comprises an open floor and closed side walls 58. The open floor is formed by a floor frame 52 in particular in the form of a grid which has a plurality of webs 53 on which the storage device 12 can be placed. Holes 54 are formed between the webs 53 of the floor frame 52, through which an only diagrammatically illustrated lifting element 62 of a lifting device 60 can gain access from below, in order to come into contact with the floor 20 of the storage device 12. At least one access region 56 for a fork of a forklift is formed in a lower side region of the base or transport rack 50.

[0037] In order to prevent damage to the cassette-shaped storage device 12, the area of the base rack 50 may be somewhat larger (space between side walls 58 of the base rack 50 and outer delimiting walls 42 of the storage device 12), and it may be greater in height with a protrusion. The preferably closed side walls 58 of the base rack 50 further reinforce the protective function.

[0038] The base rack 50 is advantageously designed so as to be stackable. The base rack 50 ensures that during transport of the apparatus 10, no or hardly any external forces can act on the cassette part or on the storage device 12.
