DESCRIPTION:
BRIEF SUMMARY
FIELD OF USE
The loading and unloading apparatus according to the invention can be used wherever it is necessary to continuously upwardly and downwardly convey bulk materials and piece goods.
PRIOR ART
An apparatus for loading and unloading particularly ships with bulk materials and/or piece goods is known from German Patent No. 1,290,875. In this loading and unloading apparatus, the rotary conveyor is positioned on the fixed conveyor, so that upwards conveying was possible without employing additional devices. However, it is necessary to provide additional devices, such as transfer rollers for downwards conveying, so that the goods to be conveyed can be transferred from the fixed conveyor onto the extendable and retractable conveyor, because the upper end of said conveyor overlaps the fixed conveyor, so that as a result of the step formed, the goods to be conveyed downwards cannot be conveyed over said step without auxiliary means.
Moreover, this apparatus does not permit the loading of ships with bulk material, because in the case of downwards conveying, the bulk material cannot be raised by the transfer rollers in the transfer area between one conveyor and the other conveyor. The desired result is also not obtained through the use of transfer plates in place of transfer rollers, because it has been found that material accumulations and blockages can then occur in the vicinity of the transfer plate, so that trouble-free downwards conveying is not possible.
PROBLEM, SOLUTION, ADVANTAGES
The present invention aims at providing an apparatus for the loading and unloading, particularly of ships, with bulk materials or piece goods, which permits an upwards and downwards continuous conveying of both bulk materials and piece goods, without additional means being required for transferring the goods to be conveyed from one conveyor onto the other conveyor and which also permits a displacement of the discharge side of the spiral conveyor to a different discharge direction, whilst permitting an adjustment of the length of the conveyor belt of the vertical conveyor.
According to the invention, this problem is solved by an apparatus for loading and unloading, particularly ships, comprising two superimposed conveyors, constructed as spiral endless conveyor belts and guided over guide pulleys in a vertical supporting frame, whereof one conveyor is fixed between the supporting frame and a central cylindrical supporting member, whilst the other conveyor is constructed in an extendable and retractable manner by rotating about the vertical supporting frame longitudinal axis, which is characterized in such a way that, the conveyor which can be rotated about its vertical spiral longitudinal axis is arranged in a supporting cage positioned below the supporting frame, said cage being mounted in rotary manner about the supporting member longitudinal axis at the bottom end of an extendable and retractable supporting member section held in the bottom area of the cylindrical supporting member of the supporting frame and which with its upper end facing the end of the fixed conveyor sectionally engages over the lower end of the fixed conveyor for upwards conveying and that after rotating the supporting cage by approximately 360.degree., the upper end of the conveyor rotatable with the supporting cage is located below the lower end of the fixed conveyor for downwards conveying.
An apparatus constructed in this way makes it possible to load and unload ships both with bulk material and piece goods without additional means being required, for transferring the goods to be conveyed from one conveyor to the other conveyor. For downwards conveying, the conveyor assumes a position in the supporting cage or basket, in which the upper end of the conveyor arranged in said cage comes to rest below the lower end of the fixed conveyor, so that it is not only possible to transfer piece goods, but also bulk material from the fixed conveyor to the conveyor arranged in the rotary cage. However, for an upwards conveying, the supporting cage with
