PATTERN REGISTRATION

Applicant; WAAGNER-BIRO AKTIENGESELLSCHAFT, WIEN ¹¹ Conveyor system for bulk goods "

The innovation relates to a conveyor system for bulk materials, in particular an unloading facility for ships.

The handling of bulk goods, such as ore, coal, grain or fertilizers, is mainly done with grab cranes accomplished. Pneumatic conveyors are also known for light bulk goods such as grain.

Unloading with grabs leads to large unloading lines expensive and complex in terms of both control technology and electricity Equipments. In addition, the interposition of a bunker is necessary. The gripper can generally not coat the entire hold so that bulldozers have to be used inside the ship. The unloading of weather-sensitive Bulky goods can only be handled using grab cranes in good weather. The pneumatic conveyance is for reasons of economy limited to fine-grained or dust-like material that must not be too abrasive. Even with zu

7G'i3162;: 2, i0.7H

If the surface hardness of the material to be conveyed is too low, a pneumatic conveyor cannot be used.

The innovation is based on the task of eliminating the defects mentioned and a continuous discharge or a continuous discharge Enable cargo handling.

This object is achieved according to the invention in that between steep conveyor systems arranged in pairs, such as for example bucket elevators or screw conveyors, a conveyor device, in particular a conveyor belt, is arranged, which is preferably horizontal or is arranged slightly inclined. Another feature of the innovation is that the steep conveyor systems, which are provided in pairs, work in the opposite sense, and each steep conveyor system is assigned a bucket elevator or a paddle wheel as a recording device.

Due to the innovation, the unloading and handling work is opposite the current state of the art and made more economical. For example, weather-endangered bulk goods can also be used can be reloaded even in bad weather, since the conveyor system ■ f can be passed through or covered by a tarpaulin. The system can still deliver its full discharge capacity. The energy consumption per unloaded ton of bulk goods is as a result the continuous work orphan is significantly reduced. Because the drive of this system was only driven at low speed must be, the control and the drive can be made simple and robust, so that the maintenance costs are significantly reduced will. The device according to the innovation can cover most of the unloading space of a ship or a storage area a simple control so that even semi-skilled workers can operate the device.

An exemplary embodiment of the innovation is shown in the drawing and is described in more detail below. Show it:

Figure 1: A combined de-icing device for ships. Figure 2: a cross view according to Figure 1, Figure 3: a cargo handling device from ship to ship, Figure 4: an embodiment of Figure 1, Figure 5: an inclined conveyor and FIG. 6: an embodiment variant of FIG. 5. I.

The conveyor system according to the innovation essentially consists of two counter-rotating steep conveyor systems 1, where appropriate a recording device, such as a paddle wheel 7 or a bucket elevator 27, can be assigned to each steep conveyor system. This steep conveyor system is followed by a movable and pivotable conveyor 2, such as a conveyor belt or a pocket belt conveyor, this conveyor system is, like it is shown in FIGS. 1, 2 and 4, held on a support structure 6 similar to a crane bridge. On this support structure 6 is a locally fixed conveyor belt 3, which connects to the moving conveyor system. To move the conveyor system is a mechanical on the support structure 6 Lifting device 4 for lifting and lowering the inclined conveyor 1, a mechanical displacement device 8, 9 for aligning the displaceable conveyor device 2, and a hydraulic adjusting device to define the working angle between the two conveyor systems 1 and 2 provided.

The support structure 6 carries all the necessary tax inputs • directions, it is designed and similar to a crane portal

j can be moved with the aid of trolleys 11. This support structure can also have a rotating device.

The receiving devices 7 (FIG. 5) and 27 (FIG. 6) take the goods to be conveyed inside the ship 29, lead it to the steep conveyor systems 1, of which it is via the discharge device 23, 24 (Figure 5) reaches the pivotable and displaceable conveyor 2 and

'<_) is supplied from this via the conveyor belt 3 to further conveyors or transport means not belonging to the unloading device. The height of the recording devices 7, 27 is controlled by the lifting device 4. The conveyor 2 is articulated with its free end in the track 9 and stored. The horizontal adjustment of the recording devices 7 and 27 takes place indirectly via the conveying device 2 through the control of the drive 8. In this way, the conveying device 2 can be both positive

■ reach as well as negatitoe inclination. For setting and determining

: the relative position of conveyors 1 and 2 is used by the hydraulic

j actuator 5.

The steep conveyor device 1 is generally of screw conveyors or bucket elevators, as shown in FIGS. 5 and 6, which are arranged in pairs and which are in opposite directions Direction of movement for conveying up the bulk material to be removed. In this way, there are only slight downforce when the material is picked up, either directly or through recording devices 7 or 27 takes place. The horizontal forces had to be with the known constructions are taken up by the boom and the supporting structure; in the arrangement according to the innovation, they are the same

however, due to the opposite direction of action, mutually in the area of the receiving device: ν., λ / or 27 from. The two steep conveyor systems 1 can, as shown in FIG. 5, be arranged parallel to one another. A construction variant is shown in ^: - 6, where they are arranged inclined to one another and are connected to one another by a cover construction so that they form a stable unit that can rotate about the axis 22.

The recording devices 7 and 27 are at the lower end of each inclined conveyor attached and have their own drive 21.

Between the steep conveyor system 1 and the conveyor 2, which is preferably designed as a conveyor belt, chain conveyor, screw or pocket belt conveyor, is a discharge device 23, 24 arranged. The material transfer takes place in the area of the pivot point of the inclined conveyor 1 around the conveyor device, i.e. near the axis 22, the rotating device being formed by a rotating ball ring 23 and the material being formed by chutes 24 within the rotating ring 23 is passed from one to the other conveyor. The inclined conveyor 1 is operated at such a conveying speed that the material to be conveyed is thrown through the transfer device using centrifugal force.

The control of the drive for the replenishment of the receiving device 7 or 27 takes place via electrical force measuring devices 25 or depending on the current consumption of the drive motors 21 of the receiving device 7 or 27. The drive 4 for lifting and lowering the conveyor system consists of a slip ring motor with fine input, where the fine input is used to control the replenishment.

The device according to the innovation can be adjusted against each other by three drives so that in connection with a; ¹ moving or rotating all points of a spatial coordinate system can be swept by these three movements. The cable winch 4 allows the pivoting movement of the displaceable discharge belt or conveyor belt 2, so that the conveyor device can have a positive or negative inclination. The values * 30 can be viewed as limit values. By means of the hydraulic cylinders 5, the intersection angle between the axis of the steep conveyor system 1 and the conveyor device 2 can be changed within the angle * 15. By means of the drive 8, the free end 10 of the conveying device 2 can be displaced along the guide 9 above the fixed discharge belt 3.

As can be seen from Figures 1 and 2, on the conveyor system opposite side of the portal a boom 12 can be arranged, which has a foldable boom at its end 13, which can be brought into position by a winch 14. On the boom 12 is a movable angle trolley for the manipulation of piece goods, in particular of containers, 28 provided. This combined facility has mainly on short Loading moles have great advantages, where only one ship can be anchored at a time, so that you can choose between two with one loading device various unloading units (bulk and general cargo) deleted can be.

For larger ranges it is useful, as shown in Figure 4, the two conveyors 1 and 2, which are articulated to one another, on a foldable extended track, the boom 16 to feed.
