Description

(1) In the drawings:

(2) FIG. 1 shows a schematic illustration of a system for providing building materials in side view;

(3) FIG. 2 shows a schematic illustration of a system for providing building materials in plan view;

(4) FIGS. 3a and 3b show schematic illustrations of a packaging; and

(5) FIG. 4 shows a schematic illustration of an illustrative packaging.

(6) FIG. 1 illustrates an illustrative and schematically illustrated system 1 for providing building materials. The system 1 comprises a packaging 2, a lifting device 3, and a mixing and conveying device 4.

(7) In this exemplary embodiment, the packaging 2 is formed with a sleeve 5 and with a hanging device 6, wherein the sleeve 5 has a substantially cuboidal shape. Here, the sleeve 5 has a standing surface 7, lateral surfaces 8 and a top surface 9. Arranged in the standing surface 7 is an emptying device 10, and a filling device (not visible in this illustration) is provided in the top surface 9. In this case, the packaging 2 has a total height 13. In this exemplary embodiment, the total height 13 of the packaging 2 extends from the standing surface 7 to an uppermost region of the hanging device 6.

(8) In this exemplary embodiment, the lifting device 3 is embodied as a forklift truck. In this case, the lifting device 3 comprises an inverted fork 22. This inverted fork 22 has a tubular cross section, for example, with the result that the hanging device 6, which in this exemplary embodiment is designed as loops, can be operatively connected in a simple manner to the fork 22 of the lifting device 3.

(9) Through the use of an inverted fork 22, the hanging device 6 of the packaging 2 can be hung on an uppermost region of the fork 22 and also of the lifting device 3.

(10) In this exemplary embodiment, the mixing and conveying device 4 is designed as a single machine. In this case, the mixing and conveying device 4 comprises a hopper 18, or a mixing chamber 19, a feed line 20 and a discharge line 21. In this case, the first component is fed to the mixing chamber 19 from the packaging 2 via the hopper 18. With the addition of the second component via the feed line 20, the first component is mixed with the second component in the mixing chamber 19 and is then discharged from the mixing and conveying device 4 via the discharge line 21.

(11) With such a system 1 it is possible, by using a dry cement mixture as the first component and water as the second component for example, to provide mortar. At the same time, this system 1 requires little manual intervention, has a high flow rate, and can also be used in spaces with a height of 230 cm.

(12) An illustrative system 1 for providing building materials is illustrated schematically in plan view in FIG. 2. In this illustrative embodiment, the inverted fork 22 comprises four arms, wherein a respective loop of the hanging device 6 of the packaging 2 can be hung on each one of the arms. Here, the arms of the fork 22 are designed in such a way that the packaging 2 as far as possible retains its shape and is not extended in length by the weight of the first component. This can be achieved, in particular, if the respective hanging locations on the arms of the fork 22 are spaced somewhat further apart than the loops of the hanging device 6, with the result that the packaging 2 tends to be pulled apart slightly in the direction of its width and depth.

(13) Such a fork 22 with four arms has the advantage that, when picking up a new packaging 2, the lifting device 3 can be brought up to the hanging device 6 of the packaging 2 substantially from above. Once the fork 22 has been positioned next to the loops of the hanging device 6 from above, the loops can be placed over the arms of the fork 22 without the need to move the lifting device 3 during this process, either horizontally or vertically. This significantly facilitates the handling of packagings 2 by the lifting device 3, thus enabling this process to be carried out readily and efficiently by one person. Particularly in confined spaces, this is advantageous because little space is required for maneuvering.

(14) Two different packagings 2 are illustrated schematically in FIGS. 3a and 3b. Here, the packaging 2 in FIG. 3a is of cuboidal design, and the packaging 2 in FIG. 3b is of cylindrical design. The packagings 2 each have a top surface 9 having a filling device 11, lateral walls 8 and a standing surface having an emptying device (not visible in this illustration). Here, the packagings 2 have a sleeve width 16, a sleeve height 15 and a sleeve depth 17.

(15) A packaging 2 having a sleeve or cover 5 and a hanging or suspension device 6 is illustrated in FIG. 4. The hanging or suspension device 6 in this exemplary embodiment comprises four loops, which are each arranged in one upper region of the sleeve or cover 5 and are each arranged in the region of the edges between two lateral surfaces 8. In order to keep a total height of the packaging 2 as small as possible, a fixing region of the hanging or suspension devices 6 on the sleeve or cover 5 is spaced apart from an upper edge of the lateral surface by a certain distance.
