Description

[0025] The invention is explained in more detail below with reference to exemplary embodiments that are schematically shown in the Figures. In the Figures:

[0026] FIG. 1 shows a perspective view of a storage rack according to the invention;

[0027] FIG. 2 shows a vertical section through the storage rack according to the invention of FIG. 1 in the region of the service opening;

[0028] FIG. 3 shows a plan view from below of an inventive indicating device according to a first embodiment;

[0029] FIG. 4 shows a plan view from below of an indicating device according to a second embodiment;

[0030] FIG. 5 shows a plan view from below of an indicating device according to a third embodiment;

[0031] FIG. 6 shows a plan view from below of an indicating device according to a fourth embodiment; and

[0032] FIG. 7 shows a plan view from below of an indicating device according to a fifth embodiment.

[0033] FIGS. 1 and 2 show an automated storage rack 100 configured as a vertical lift. The storage rack 100 has two spaced-apart rack towers 104a, 104b with a plurality of carrier supports 105 disposed one above the other for supporting stored goods carriers 106. An automatic transport device 108 is movably disposed between the spaced-apart rack towers 104a, 104b. By means of the automatic transport device 108, the stored goods carriers 106 can be moved to a service opening 110 for delivering and removing stored goods 102. The service opening 110 has an upper side 111, a lower side 112 and an access window 113.

[0034] The first horizontal direction y extends along the depth, and the second horizontal direction x extends along the width, of the service opening 100. The depth of the service opening 110 extends along the first horizontal direction y, and the access window 113 extends along the second horizontal direction x. For delivering and removing stored goods 102, the service opening 110 is accessible via the access window 113, which faces towards an operator 200.

[0035] An indicating device 10 having a bar-shaped lighting device 12 for indicating stored goods 102 is arranged on the upper side 111 of the service opening 110. The lighting elements 14 each emit a light beam 15 that is directed substantially vertically downwards onto the stored goods 102.

[0036] The structure of the indicating device 10 is described in detail in FIG. 3. Advantageous embodiments of the indicating device 10, which may also be combined with one another, are described by means of FIG. 4 to FIG. 7. The same reference numerals are being used for components of the indicating device 10 shown in FIGS. 3 to 7 that are the same or the same in function.

[0037] FIG. 3 shows the indicating device 10 with a lighting device 12. The lighting device 12 has a bar-shaped configuration and extends along the first horizontal direction y. The lighting device 12 has a plurality of lighting elements 14 which are arranged with an offset from one another in a row 16 along the bar-shaped lighting device 12. Along the second horizontal direction x, the lighting device 12 is guided and movable on a rail 18. The rail 18 can be installed on the upper side of the service opening 110, for example, so that the indicating device 10 is located in the upper region of the service opening 110.

[0038] The lighting device 12 is moved along the rail 18 by means of a controllable drive unit 20. The drive unit 20 is configured to carry out rapid movements of the lighting device 12, so that characters, for example, can be projected by means of the indicating device onto a surface, such as the lower side 112 of the service opening 110, for instance. A rough sketch of an hourglass, for example, which is used as a symbol for waiting until the stored goods carrier 106 is inserted into the service opening 110, is to be understood to be a character.

[0039] The lighting elements 14 can be controlled individually or in groups. It may also be provided that the lighting device 12 emits light in different colors. For example, it may be provided that, in the case of several stored articles stored one behind the other, the desired stored article is indicated with green, and the articles situated to the front and the rear thereof in space are indicated with red. Moreover, it may also be indicated in different colors if the stock drops below a minimum level.

[0040] FIG. 4 shows another indicating device 20, which differs from the indicating device 10 according to FIG. 3 in that the plurality of the lighting elements 14 extends along three rows 16a, 16b, 16c extending side-by-side along the first horizontal direction y.

[0041] FIG. 5 shows another indicating device 30, which differs from the indicating device 10 according to FIG. 3 in that several lighting devices 12a, 12b, 12c are arranged to be movable along the second horizontal direction. A first drive unit 20a is assigned to the first lighting device 12a, a second drive unit 20b is assigned to the second lighting device 12b, and a third drive unit 20c is assigned to the third lighting device 12c. The lighting devices 12a, 12b, 12c are separately controllable.

[0042] FIG. 6 shows another indicating device 40, which differs from the indicating device 10 according to FIG. 3 in that the lighting device 12 additionally has a camera 22. The field of view of the camera 22 is also directed substantially vertically downwards. Moreover, the camera 22 may have a lens with a fixed focal length, which makes it possible to capture the entire storage rack. In order to record an image, the lighting elements 14 may serve for lighting.

[0043] FIG. 7 shows another indicating device 50, which differs from the indicating device 10 according to FIG. 3 in that the lighting device 12 has two rails 18a, 18b. The rails 18a, 18b are positioned in the area of the edge of the lighting device 12.

[0044] In order to deliver and retrieve stored goods 102, the operator 200 enters a picking order into a control device. The stored goods carrier 106 with the requested stored goods 102 located on the stored goods carrier 106 is transported to the service opening 110 by means of the transport device 108. Then, the position of the stored goods 102 on the stored goods carrier 106 is indicated to the operator 200 by means of the indicating device 10, via the light beam 15. For this purpose, the lighting device 12 moves along the second horizontal direction x until it is positioned above the storage location of the stored goods 102. Then, only those lighting elements 14 along the first horizontal direction y are activated that are required for indicating the storage location of the stored goods 102 in the depth direction.

[0045] Since the lighting elements 14 can be mounted up into the areas of the edges of the lighting devices 12 and the lighting device 12 extends across the entire depth of the stored goods carriers 106 and can be moved along the entire width of the stored goods carrier 106, an exact indication of stored goods 102 on the entire stored goods carrier 106 can be ensured. Even stored goods 102 positioned in areas of the edges of the stored goods carrier 106 can be indicated without being concealed.

[0046] The indicating device 10 according to the invention is characterized by a simple and inexpensive structure and versatile applicability. Above all, the subsequent installation in a service opening 110 of a storage rack 100 is possible.
