[0080] The unloading system 2 shown in
[0081] The unloading device 4 comprises a tilting unit 16 and a platform 18. The tilting unit 16 and the platform 18 have a common rotational axis 20, about which the tilting unit 16 and the platform 18 are able to be moved. The unloading device 4 has a mechanical shaft 22 for this purpose, on which on the one hand the tilting unit 16 and on the other hand the platform 18 are supported.
[0082] The platform 18 is able to be positioned in a flipped down position and in a flipped up position. In
[0083] In the flipped down position of the platform 18 (also: in the flipped down state of the platform 18) the support surface 24 of the platform 18 and the support surface 24 of the leveler 14 form an at least essentially continuous support surface 25.
[0084] When the platform 18 is flipped up or flipped down a movement of the platform about the aforementioned rotational axis 20 takes place (cf.
[0085] Then, when a laterally open large container 8 is positioned on the tilting unit 16, the platform 18, in the flipped up position, closes an opening side 52 of the large container (cf.
[0086] The tilting unit 16 is shown in
[0087] The tilting unit 16 is configured, during transition of the platform 18 from the flipped up position into the flipped down position—in particular starting from the initial position of the tilting unit 16—to tilt together with the platform 18 about the common rotational axis 20 in such a way that the position of the platform 18 does not change relative to the tilting unit 16 (cf.
[0088] This means that the tilting unit 16 is configured, during transition of the platform 18 from the flipped up position into the flipped down position—in particular starting from the initial position of the tilting unit 16—to tilt together with the platform 18 about the common rotational axis 20 in such a way that the tilting unit 16 carries out a movement about the common rotational axis 20 with the same angular speed and in the same direction as the platform 18 does at the same time.
[0089] The tilting unit 16 is further configured, after tilting, to return to the initial position, wherein the platform 18 remains in the flipped down position.
[0090] During the tilting process the tilting unit 16 moves from its initial position into a tilted position of the tilting unit 16. The tilting process can further comprise a transition of the tilting unit 16 from its tilted position back into its initial position.
[0091] The unloading device 4 has a conveyor means 28 which is configured to convey the large container onto the tilting unit and to position it.
[0092] In this example the conveyor means 28 for positioning the large container is embodied as a roller conveyor 30. The roller conveyor 30 comprises a number of conveyor rollers 32. In this example slats 34 are arranged between the conveyor rollers 32. The slats 34 are elements of the unloading device 4, in particular elements of the tilting unit 16. The conveyor rollers 32 project with their upper edge from between the slats 34, so that a force transmission to a large container 8 arranged thereon (cf.
[0093] The slats 34 make it possible easily to step onto the roller conveyor 30, to open the side of a large conveyor 8 for example. The slats 34 further prevent objects falling between the conveyor rollers 32 and thereby causing the conveyor rollers 32 to jam.
[0094] In principle however other conveyor means 28 are also possible.
[0095] In this exemplary embodiment the conveyor means 28 for positioning the large container 8 is a part of the tilting unit 16. This means that the tilting unit 16 is tilted with the conveyor means 28 for positioning the large container 8 during the tilting process.
[0096] In principle the conveyor means 28 for positioning the large container 8 can also be separate from the tilting unit, so that the conveyor means 28 is not tilted as well during the tilting process. For example the slats 34 can be tilted as well during the tilting process, while the conveyor rollers 32 remain in their position during the tilting process, i.e. are not tilted as well.
[0097] The unloading device 4 comprises a latching apparatus 36 for latching a large container 8 positioned on the tilting unit 16. When a large container 8 is positioned (cf. FIG. 4), the large container 8 is latched onto the tilting unit 16 using the latching apparatus 36.
[0098] In this exemplary embodiment the latching apparatus 36 has a number of engaging elements 38 for engaging onto a lower edge of the large container 8.
[0099] The latching of the large container 8 enables a fixed positioning of the large container 8 in relation to the tilting unit 16 to be achieved during the tilting process.
[0100] The tilting unit 16 has a frame-shaped stop 40. The frame-shaped stop has a cutout 41. The frame-shaped stop 40 is arranged vertically. In particular the frame-shaped stop 40 is at right angles to a support surface 24 of the tilting unit 16, on which support surface 24 the large container 8 can lie (see also
[0101] The frame-shaped stop 40 has a first side 42 and a second side 44 opposite the first side 42.
[0102] When a laterally open large container 8 is positioned on the tilting unit 16, then the opening side 52 of the large container 8 rests against the first side 42 of the frame-shaped stop 40 (cf.
[0103] By means of the frame-shaped stop 40 an improved force transmission from the tilting unit 16 to a large container 8 can be achieved. Moreover by means of the frame-shaped stop 40 a fixed positioning of a large container 8 in relation to the tilting unit 16 can be achieved during the tilting process.
[0104] In the flipped up state the platform 18 rests against the second side 44 of the frame-shaped stop 40 (cf.
[0105] The platform 18 has a conveyor means 46 for transporting away bulk goods 6. The conveyor means 46 for transporting away bulk goods 6 is embodied in this example as a belt conveyor 48. By means of the conveyor means 46 for transporting away bulk goods 6 bulk goods 6 lying on the platform 18 can be fed to the separation unit 10.
[0106] The platform 18 further has lateral delimiting elements 50. By means of the delimiting elements 50 a guidance of bulk goods 6 can be achieved. In particular bulk goods 6 can be prevented from falling down off the sides of the platform 18 by the delimiting elements 50.
[0107] Moreover a conveyor means 56 for feeding large containers 8 is shown in
[0108] In this example the conveyor means 56 for feeding large containers 8 is embodied as a roller conveyor 30. In principle the conveyor means 56 can also be a belt conveyor, a conveyor truck, a conveyor crane etc. however.
[0109]
[0110] The large container 8 in this example is a transport container, in particular a Unit Load Device.
[0111] The large container 8 is fed to the unloading device 4 by means of the conveyor means 56 for feeding large containers 8.
[0112] The side of the large container 8 is opened. This step can for example also be carried out manually. It is further possible for the large container 8 to be fed to the unloading device 4 already laterally open.
[0113] The opening side 52 of the large container 8, i.e. the side on which the large container 8 is laterally open, points toward the frame-shaped stop 40 of the tilting unit 16. This means that here the opening side 52 points to the right in accordance with the drawing.
[0114] Using the conveyor means 28 for positioning the large container 8, the large container 8 is positioned on the tilting unit 16. The conveyor rollers 32 of the conveyor means 28 embodied as a roller conveyor 30 are shown as dashed lines in
[0115] The large container 8 is positioned on the tilting unit 16 in such a way that the opening side 52 of the large container 8 rests against the frame-shaped stop 40 of the tilting unit 16 (see
[0116] The first side 42 of the frame-shaped stop 40 is shown as a dashed and dotted line.
[0117]
[0118] The large container 8 is positioned on the tilting unit 16 in such a way that the opening side 52 of the large container 8 rests against the frame-shaped stop 40 of the tilting unit 16.
[0119] The positioned large container 8 rests with its opening side 52 against the first side 42 of the frame-shaped stop 40.
[0120] The cutout 41 of the frame-shaped stop 40 is at least essentially as large as the opening of the opening side 52 of the large container 8.
[0121] Because of the cutout 41 of the frame-shaped stop 40 the opening side 52 of the large container 8 is not closed by the frame-shaped stop 40.
[0122] The positioned large container 8 is latched on the tilting unit 16, in particular for the tilting process, using the latching apparatus 36. For latching the large container 8 the number of engagement elements 38 of the latching apparatus 36 engage in a lower edge 54 of the large container 8.
[0123] The latching of the large container 8 enables a fixed positioning of the large container 8 with regard to the tilting unit 16 during the tilting process to be achieved.
[0124] In
[0125] The support surface 24 of the platform 18 is hidden by the lateral delimiting element 50, but is shown as a dashed and dotted line.
[0126] When the platform 18 is flipped up the tilting unit 16 remains in its initial position.
[0127] In principle the platform 18 could also already be flipped up when the large container 8 is positioned on the tilting unit 16 (not shown).
[0128]
[0129] The platform 18, in the flipped up state, rests against the second side 44 of the frame-shaped stop 40.
[0130] The platform 18, in its flipped up position, closes the opening side 52 of the large container 8.
[0131]
[0132] In this process the tilting unit 16, together with the large container 8 located thereon and the platform 18 closing the opening side 52 of the large container 8, is tilted about the common rotational axis 20 in such a way that the large container 8 is positioned on its opening side 52 (cf.
[0133] During tilting the platform 18 goes from its flipped up position (cf.
[0134] On transition of the platform 18 from the flipped up position into the flipped down position, the tilting unit 16 tilts together with the platform 18 about the common rotational axis 20 in such a way that the position of the platform 18 relative to the tilting unit 16 does not change. This means that the platform 18 closes the opening side 52 of the large container 8 during the tilting.
[0135] During the tilting the tilting unit 16 goes from its initial position (CF.
[0136] The tilting unit 16 and the platform 18 are tilted about the common rotational axis 20 by an angle 58 of 90° (see
[0137] The frame-shaped stop 40 and/or the latching prevent the large container 8 from slipping and/or tilting away during this process.
[0138] During tilting the bulk goods 6 in the large container 8 slide in the direction of the opening side 52 of the large container 8 and thus in the direction of the platform 18. In this way the bulk goods 6 are deposited on the platform 18. Since the bulk goods 6 do not fall down the bulk goods 6 are protected.
[0139]
[0140] In
[0141] The large container 8 is positioned on its opening side 52. The bulk goods 6 lie on the platform 18. It is possible that individual bulk goods 6 are still leaning against the wall of the large container 8 (not shown), but the bulk goods 6 are lying on the platform 18 instead of on the large container 8.
[0142] After the tilting, i.e. starting from the tilted position of the tilting unit 16 (
[0143] During tilting back the platform 18 remains in the flipped down position. This means that the bulk goods 6 remain on the platform 18. This also means that the tilting unit 16 is tilted back together with the emptied large container 8.
[0144] In this way the bulk good 6 or the bulk goods 6 can be unloaded from the large container 8.
[0145]
[0146] The bulk goods 6 lying or remaining on the platform 18 are then transported away by means of the conveyor means 46 for transporting the bulk goods 6 away from the platform 18. In particular the bulk goods 6 are fed from the platform 18 to the separation unit 10 of the unloading system 4 shown in
[0147] By means of the separation unit 10 a one-dimensional flow of bulk goods is created.
[0148] Although the invention has been illustrated and described in greater detail by the preferred exemplary embodiments, the invention is not restricted by the disclosed examples and other variations can be derived herefrom by the person skilled in the art without departing from the scope of protection of the invention
