Description

[0038] The invention will be explained in greater detail below with reference to the non-limiting embodiment variants shown in the figures, in which:

[0039] FIG. 1a shows a schematic side view of a first embodiment of a device according to the invention;

[0040] FIG. 1b shows a schematic side view of a second embodiment of a device according to the invention;

[0041] FIG. 2 shows part of a receiving unit with different embodiments of receiving area rows, in a plan view;

[0042] FIG. 3 shows a schematic oblique view of a temperature control medium line;

[0043] FIGS. 4a and 4b show one embodiment of a receiving area in a sectional view.

[0044] FIG. 1a shows a device 1 in a first embodiment, having a gripper arm 100, which is movable in all directions 102, and three receiving units 10. The receiving units 10, connected in parallel, are supplied with temperature control medium from a heat sink 202 comprising a compressor, that is to say a cooling system. To this end, each inlet line 200 of the receiving units 10 is connected to a supply line 201 of the heat sink 202, and each outlet line 203 of the receiving units 10 is connected to the return line 204 of the heat sink 202. Each receiving unit 10 has a total of ten receiving area rows 12, each having a plurality of receiving areas 3, into which items 2 to be stored can be inserted by the gripper arm 100 through a hole 31. The receiving areas 3 of each receiving area row 12 are arranged in a row, the receiving area rows 3 being arranged next to one another. The receiving area rows 3 are supplied in series by the supply line 201 and discharge the used temperature control medium via the outlet line 203.

[0045] Each receiving unit 10 additionally has a thermally insulating casing 11. The receiving units 10 are thus substantially independent of one another, and if one receiving unit 10 is unplugged or becomes defective there is no general failure of all the other receiving units 10. Furthermore, the temperature-controlled chamber is thus kept as small as possible; the gripper arm 100 need not be arranged in the interior of the temperature-controlled chamber. The items 2 to be stored may protrude upwards out of the temperature-controlled areas, but this does no harm since this surface area is very small and the product is pulled by gravity into the lower part of the item 2 to be stored, so that the product in the item 2 to be stored can be kept at a constant temperature and the energy losses are low. Alternatively, thermally insulating closure mechanisms such as flaps may be provided, which upwardly close the item 2 to be stored and can be automatically opened by the gripper arm 100.

[0046] Here, directional indications such as top or bottom are based on the device 1 being arranged as intended, in which the holes 31 of the receiving areas 3 substantially point away from the Earth's surface. However, it must be noted that embodiments in which the receiving areas 3 have other orientations are also possible.

[0047] The gripper arm 100 can move items 2 to be stored between the receiving areas 3 or between the receiving areas 3 and an input/output surface 101. Items 2 to be stored can thus simply be arranged on the input/output surface 101 so that the gripper arm 100 can stow them in the receiving areas 3. When a stored item 2 is required, a command can thus be sent to the gripper arm 100 via an input unit, such as a computer interface, in order to initiate the removal from storage. Means such as barcode readers, RFID systems or the like may be provided, which recognize the items to be stored and automatically arrange them in a storage system.

[0048] In an alternative embodiment, each receiving unit 10 may have its own heat sink 202, or optionally a heat source. The receiving units 10 need no longer be connected via a common supply line 201 and/or return line 204.

[0049] Within each receiving unit 10, the receiving areas 3 are arranged in receiving area rows 12. Each receiving unit has two line strands 7, which cool the receiving areas 3 and are arranged on each side of the receiving areas 3 of the receiving area rows 12. The line strands 7 are connected to one another in series, the transition lines 15 between the line strands 7 being insulated in order to avoid thermal losses. This results in a single temperature control medium path within the receiving unit 10. Alternatively, the receiving area rows 12 may also be arranged parallel to one another.

[0050] FIG. 1b shows an alternative, second embodiment, which is very similar to the first. Only the main differences will be discussed here. One heat sink 202 is assigned to each receiving unit 10. This results in three completely independent, easily transportable functional units 206 which can be operated and moved independently of one another. In the embodiment shown, they are arranged one above the other within the range of motion of the gripper arm 100, so that the gripper arm 100 can populate them. Here, “one above the other” is meant in relation to the ground. Alternatively, each functional unit 206 can also be used without a gripper arm 100, by populating it manually.

[0051] FIG. 2 shows part of a receiving unit 10, wherein two receiving area rows 12 with receiving areas 3 arranged in rows therein are shown in part. For a better view, two differently configured receiving area rows 10 are shown. All the receiving areas 3 have a cylindrically shaped receiving opening 4.

[0052] Each receiving area 3 of a first receiving area row 12 has two temperature control medium lines 5 which are configured to be elastic, said lines having a circular segment-shaped cross-section in the region of the receiving opening 4. One temperature control medium line 5 forms one half and a first part of the lateral surface of the cylindrically shaped receiving opening 4, and the other forms the other half and thus a second part of the lateral surface. Together they thus form a pocket which, when an item 2 to be stored is inserted into a hole 6 of the receiving opening 4, expands to such an extent that the item 2 to be stored easily fits and at the same time is secured counter to the force of gravity. The temperature control medium lines 5 are connected to the temperature control medium lines 5 of the adjacent receiving areas 3, so that temperature control medium, after flowing through the temperature control medium lines 5 of one receiving area 3, can flow through the temperature control medium lines 5 of the adjacent receiving areas 3. This results in two continuous line strands 7, which connect the receiving areas 3 to one another. The temperature control medium lines 5 are connected to one another at one end and thus the flow therein takes place in different directions, as shown by arrows 205.

[0053] The receiving areas 3 of the second receiving area row 12 each have only one temperature control medium line 5, which likewise have a circular segment-shaped cross-section, these covering more than half of the lateral surface. They are also connected to temperature control medium lines 5 of the adjacent receiving areas 3. This results in a Q shape of the temperature control medium lines 5, which form pockets for the items 2 to be stored. The temperature control medium lines 5 of the adjacent receiving areas 3 are arranged on different sides of the lateral surface. This results in an alternating orientation of the pockets along the row of receiving areas 3.

[0054] The substantially straight connecting regions 16 of the line strands 7 between the receiving areas 3 are preferably thermally insulated.

[0055] At least in the region of the receiving openings 4, the temperature control medium lines 5 are configured to be so elastic that no further spring element is necessary. FIGS. 4a and 4b show an alternative embodiment, in which additional spring elements are provided.

[0056] FIG. 3 shows part of a line strand 7 of one receiving area row 12 from FIG. 2. It can be seen here that the line strand 7 is configured as a one-piece flat hose which includes all the temperature control medium lines 5 of this strand. This results in multiple, curved temperature control medium lines 5 which have flat regions that provide a large connection area to the item 2 to be stored. A main flow 6 flows from an inlet 8, along the lateral surfaces of the receiving openings 4, to an outlet.

[0057] A flow through the temperature control medium lines 5 thus takes place in such a way as to flow tangentially around the main axis of the items 2 to be stored. This main axis thus extends substantially along the direction of insertion into the receiving area 3. This enables not only a uniform cooling of the item 2 to be stored, but also a simple series cooling arrangement of multiple receiving areas next to one another. Alternatively, the flow through the temperature control medium lines 5 may also take place axially for example.

[0058] FIGS. 4a and 4b each show the same receiving area 3 with different items 2 to be stored arranged therein. Between a fastening wall 9 and the two temperature control medium lines 5 arranged at the same height, spring elements 14 are provided at three different heights of the receiving opening 4, said spring elements being configured as steel springs. These push the temperature control medium lines 5 into the receiving opening 4, thereby narrowing the latter. The receiving opening 4 has a height H which is bounded at one side by the hole 31 and at the other side by a boundary wall 32. The temperature control medium lines 5 extend over the entire height H. In an alternative embodiment, the boundary wall 32 may also be arranged at a distance from the temperature control medium lines 5, as a result of which it is possible to store even longer items 2 to be stored. The spring elements 14 should be so flexurally rigid that they even secure items 2 to be stored that do not extend as far as the boundary wall 32.

[0059] If, as shown in FIG. 4a, an item 2 to be stored that is of small diameter is inserted, the walls of the item 2 to be stored push the temperature control medium lines 5 outwards. The elastic spring elements 14 yield and enable the insertion, with the temperature control medium lines 5 bearing against the item 2 to be stored and securing it in position to such an extent that it cannot leave this position and fall through without external force being applied.

[0060] If, as shown in FIG. 4b, a thicker item 2 to be stored is inserted, the spring elements 14 correspondingly yield elastically to a greater extent, as a result of which also this item can be received and secured.

[0061] The spring elements are evenly distributed in the cross-section of the receiving opening 4 and are configured to be equally elastic, so that a stored item 2 to be stored is always centred in the receiving opening 4, regardless of its size. The item 2 to be stored is thus secured in a defined position. This is particularly advantageous when being removed from storage by a gripper arm 100.
