Description
~32~3'~7 The present in-vention relates to a crane system having a single-lane, discontinuous conveying system for the part-load transport of in particular bags, boxes, palletted goods or the like, essentially consisting of one or a plurality of vertical conveying lines and horizontal conveying lines lodged therebetween, with various load-receiving means and an optionally formed or changeable supporting structure.
Several measures are known for transshipping smaller part-loads in transshipping points with warehouses, several railroad tracks and/or truck runways and wharves. Bags, boxes or the like are stacked on pallets and ~hese are transferred indivually or by twos on a crane hook. The conveying cycle is essentially limited by the time required for the double conveying path. Moreover,for security reasons, it is not possible to transship un~orted goods. The use of containers coming up to international standards iH not always possible due to their dimensions, it require~ international administrative organizations, large storage surfaces and high capital investment. The further known use of continuous conveyors for sackæ and boxes requires manual labor at the loading and unloading points. Difficulties aries in adjusting the conveying system to changing conveying heights and widths and to reversed conveying direction. This also applies similarly to the continuous conveying of pallets.
DE-05 1,906,212 de~cribes a container crane provided with vertical and horizontal conveying lines for part-load transport, the containers being transferable from one or mor vertical conveying mean~ to one or more horizontal conveying means. Vertical and horizontal conveying lines in thi~
apparatus are connected without crossings, which clearly shows that this system only allows a direct transfer of the transported part-loads from the vertical to the horizontal ~32~7 conveying gear. This known apparatus does not provide for the possibility to store empty containers in turnouts in stand-by position. This publication proposes a double-lane embodiment for increasing the conveying output. DE-OS l,950 r 176 also proposes a multi-lane apparatus.
The principle of the present invention, the tripled transshipping output at single-lane conveying system, is not disclosed in any of these prior publications. This means that according to the state of the art, an increase in part-load transfer based on parallel conveying lines requires a correspondingly high construction expenditure ~e.g. two hoisting gears seaward as well as landward as well as two horizontal conveying lines with the associated conveying gear according to DE-OS l906,2l2~.
DE-OS 2,539,968 algo describes a crane system having a double-lane horizontal conveying line in a major portion of its total length. The main purpo~e of this construction i~ to serve as a bumper for several containers; it does not lead to an increa~e of the tran4shipping output.
It is the object of the present invention to provide a crane system of the type initially men1ioned which is of simple construction and full transport safety and at the same time offers an essential increase of the transshipping output. In addition to fully secured pallet load~, it is to be possible to tran~ship unsecured stacks of boxes and unsorted conveying cargo.
This object is achieved according to the invention by providing one or a plurality of turnouts for returned transport means along the entire single-lane con~eying path with it~ vertical and horizontal conveying lines and by disposing transfer points in the intersection areas of the vertical and horizontal conveying lines where the load-~32l~3~7 receiving means of the transport means are changed.
The measures according to the invention areadvantageously applied in crane systems having two vertical conveying lines and one horizontal conveying line, two turnouts being provided and three load-receiving means and three transport mean~ being used. Accordin~ to a particular embodiment, the turnout~ are disposed on both sides in the direct extension of the horizontal conveying line.
The present invention permits high availability of the transport means at the material inlet or outlet sites for the transfer or receiving of the conveying cargo for instance by means of generally available fork-lift trucks. This mean~
that only short interruptions at the material inlets and outlets are required. In spite of the single-lane construction of the conveying sy~tem, the return of empty transport means for repeated use simultaneously with a loading or unloading operation staggered in time i~ possible.
In order to assure full transport safety, the transport ~eans in the mo~t general case are for~ed as closable containers, but may be simplified in the case of uniform cargo or provided with clamping means.
The novelty of the present invention resides in that as a result of the introduction of turnouts for intermediate ~torage, a temporal interlocking of the vertical and horizontal conveying operations is made po~sible. In the case of a crane with two vertical conveying lines and one horizontal conveying line and two tran~fer points provided with turnouts according to the invention and three load-receiving means and transport means, for instance, thi~
permit~ the tripling of the transshipping output. It i8 important to note that this is achieved at total driving power and supporting structure of the crane system remaining LI i7 , virtually unchanged~ It is further worth noting that high transshipping output is achieved at full operational and transport safety and at minimum space reguirement at the material inlets and outlets.
According to one embodiment of the invention, the hoisting gears are provided with a spreader-like load-receiving means, so that the transport means can be rapidly ccupled and uncoupled. According to another embodiment of the invention, the vertical conveying lines are realized with elevating platforms. The vertical conveying lines can be made weatherproof by enclosing them by a stationary hoisting shaft or a telescopic casing. For reasons of weatherproofing, it is convenient to protect the horizontal transport by placing the line inside of the bridge girder of the crane. The drives for the horizontal conveying, the turnouts and the transfer points can basically have any given form used in the art of heavy cargo conveying.
A number of elaborate measures for adapting continuous conveyors to a mutually independently changing level of material inlets and outlet~ are known. In vertical conveying lines operating according to the paternoster or ~piral conveying system, the upper suspension point of the vertical conveying line~ must be changed to the same extent by lifting or lowering the following horizontal conveying line.
It ist thus a further ofject of the invention to provide a crane ~ystem of the type initially mentioned which at simple construction principle permits the loading and unloading of cargo at any given level at full operational safety.
This ob~ect is achieved according to the invention by providing loading stations at the lower ends of the vertical conveying lines enclo~ed by telescopic conveying ~hafts and disposing a plurality of load-receiving mean~ along the 132~7 horizontal conveying line and by providing for the ~upporting structure to have the form of in particular portal cranes, semiportal cranes, bridge cxanes and derricking jib cranes having a rigid or horizontally displaceable or privotal crane boom.
Details and advantageous embodiments of the invention are explained in the following on the basis of an exemplary embodi~ent under reference to the accompanying drawings wherein Fig. 1 is a diagrammatic representation of a conveying system according to the invention;
Fig. 2 shows an embodiment of a crane system in elevational view;
Fig. 3 shows a time diagram associated with Fig. 2;
Fig. 4 shows a transfer point with turnout in elevational view;
Fig. 5 i8 a sectional view along line A-A in Fig.4; and Fig. 6 shows an axiometric representation of a loading station with cable shaft guiding means.
The movements on the ~ingle-lane conveying path with its vertical conveying lines 1 and horizontal conveying lines 2 are staggered in time in such a manner that transport means T
running in opposite direction meet at the turnout and are intermediately stored there. Fig. 2 shows how the transport mean~ T1 is conveyed upwards by the load-receiving means Ll and immediately transferred on reaching the transfer point 4 to the load-receiving means L2 for horizontal conveying. In an unloading operation, the empty transport mean~ T2 arrive~
from the material outlet via the horizontal conveying line 2 and the tran~fer points 4 at the turnout 3 shortly hefore the completed hoi~ting operation of the loaded transport means T1 and passes T1 on returning to the transfer point 4 from where 132~ ~,.q.
it is taken over by the load~receiving means L1 for descending. At the other end of the horizontal conveying line 2 changeable in length, this operation takes place in analogy, so that the time schedule according to Fig. 3 results for the three transport means T1, T2, T3. Loading stations 10 are provided on the lower ends of the vertical conveying lines 1 for the loading and unloading of the conv~ying system, as shown in Fig 2. The individual tran~port means T are descended to the loading stations 10 by a cable hoisting gear 8 on the respective load-receiving means L1, L3. Cables 11 are fastened to the loading stations and ten~ioned hy winding gears 9 so that they form a cable shaft for the load-receiving means L1, L3. The cables 11 are made to pass through guide lugs on the load-receiving means L1 and L3. Adjacent the loading stations 10 on top are telescopic conveying shafts 6 wholly or partially enclosing the vertical conveying line 1.
The loading stations 10 may be variably equipped, for instance with counting and measuring means for the transport mean~ T, automat.ically opening doors on the loading stations 10 provided with photoelectric barrier~ or control platforms for intervening in the otherwise automatic control sequence of the conveying system. When using containers with rolling doors as the transport means T, the loading ~tations 10 and containers may be realized in such a manner that the doors are automatically slid into the ceiling of the container on running the container into the loading station 10.
According to one variant of the loading station, it is provided with a di~pensing means (for instance a car on telescopic rail~ on which the tran~port means T may be set down and run out laterally. Thiæ allows, for instance, the transfer of the transport means T on various flooræ of a ~32~3~
warehouse.
The measures according -to the invention are conveniently applied in particular in crane systems for unloading ships because a loading station 10 with telescopic supporting legs 20, the station 10 being independent of the shaft, is adjustable to the various levels and inclinations of a ship's hold (Fig. 6). It is further possible to provide the lower edge of the separate telescopic shaft with a weather protection cover of adjustable size and position ~for instance to cover ship'g hatches against atmospheric exposure).
A plurality of load-receiving means L2, L2' is provided on the horizontal conveying line 2 for a continous transfer of the individual transport means T in the transfer points 4.
These load-receiving means on the horizontal conveying line 2 are formed in such a way that are capable of transferring or receiving the transport means T in the transfer points 4~ The load-receiving means L2' is provided with fork-~haped pick-up supports 12 which can be raised and lowered and laterally enter the load-receiving means L2 on receiving the transport means T. Fig. 2 shows the condition in which an empty transport means T2 has been taken over by the load-receiving means L2' and conveyed to the turnout 3. Now, a loaded transport mean~ T1 can be lifted off the ship or railroad car to be unloaded and brought to shore. In the meantime, the empty transport meanY T~ can be conveyed by the load-receiving-means L2' to the transfer point 4 an taken over by the load-receiving mean~ L1 to be lowered onto the ship or car. As previously described, the load-receiving ~eans L1 is made to pa~s through the cable shaft mounted on khe loading station 10 on being lowered.
The loading station 10 i~ provided with axle~ 23 in~erted `` ~32~4L;7 into a frame 17 for supporting folding gangboards 19 in order to allow driving into the loading station with a stacker truck. When the gangboards 19 are folded into the side walls 18, the load-receiving means Ll or L3 can be lowered down to the frame 17 of the loading station 10.
The cable hoisting gear 8 of the vertical conveying line 1 and the winding gear 9 for the cable shaft are arranged independently of one another and transversely in relation to the direction of the crane boom for allowing adjusting movements.
Deviations of the vertical conveying lines 1 and the horizontal conveying lines 2 from the exact vertical or horizontal are within the scope of the invention for increasing the transshipping output of a discontinous conveying system. The conveying system according to the invention was shown in the exemplary embodiment illustrated by means of a portal crane with horizontally displaceable crane boom for railroad car unloading for the sake of clarity.
Within the scope of an embodiment according to the invention with discontinously operating overall system, the transport means may partly be conveyed by continously circulating drives or transport means moving in opposite directions may meet in double-lane turnout~ in otherwi~e ~ingle-lane conveying paths.
