CARGO SHIP WITH INTEGRATED STORAGE

For transport on inland waterways, it is interesting to transport, in addition to traditional transport of bulk bulk materials such as coal, ore, gravel and the like, sea containers that are placed with a lorry on the inland port quay and with the aid of crane installations in the cargo hold and / or on the loading deck of the cargo bed. inland cargo ship. At the arrival port 10, the containers are then removed from the cargo ship in a corresponding manner using crane installations so that they can be transported further to the final destination location with a truck. If the cargo ship calls at several ports of arrival one after the other, then when loading the cargo ship it must be ensured that first the container to be unloaded is also placed stand-free in the upper container so that it can be unloaded in each case without conversion.

However, this loading technique is not feasible with 20 small-sized piece goods, such as those transported on Euro pallets, for example. Such general cargo on Euro pallets cannot be handled on the one hand with the usual crane installations.

On the other hand, it is often necessary for this purpose, for example, to transport bottle-filled beverage crates that are bound together on pallets (pallets) into large bundles, to a target location and to take up empty material bound back together on pallets into similar bundles, and to take it up again in a similar manner and to be transported back to 30 the departure port.

It is an object of the invention to solve the above problem for piece goods, in particular piece goods arranged on Euro pallets.

This object is achieved according to the invention by a storage rack for objects integrated in a cargo hold of a cargo ship, in particular objects arranged on transport pallets, which has at least two loading surfaces arranged above one another, each loading surface comprising at least two longitudinally of the cargo ship has extending storage tracks, which are each provided with longitudinal conveying means for the transport pallets included, and wherein at least one end of a loading surface 10 a transverse conveying device for converting the transport pallets from one storage track to another storage track is arranged in the same plane, and furthermore a loading and unloading device is arranged at the other end of the loading surface, which loading device is movable transversely to the storage tracks 15 and which is provided with a lifting platform that is movable up and down, which has drivable movement elements, whereby the at least one on the lifting platform transport pole t is optionally movable in the longitudinal direction of the storage tracks or transversely thereto. In the following, the term "transport palette" also means general cargo.

With such a equipped cargo ship, it is possible to place an object, in particular a transport pallet, on the lifting platform in the loading port, and then by moving the lifting platform vertically and / or horizontally transversely of the longitudinal direction of the storage tracks, the object picked up on a lifting platform. store predetermined storage lane in a predetermined storage area. Via the longitudinal transport means, the discarded object can then be moved in the direction at the end of the storage track or again in the direction of the lifting platform.

Particularly advantageous is the use of a cargo ship equipped according to the invention for 1023472

• I

3 transport and the distribution of beverage crates that have been combined on transport pallets, for example so-called Euro palettes, into correspondingly large bundles. In the loading port, on the individual loading surfaces of the storage racks, the storage tracks are completely filled to the end, in which a pallet is placed one after the other on the storage track to be filled each time, the storage track being taken over each time the next pallet is taken over from the lifting platform. one pallet width is moved further until the storage track is completely filled. In this way the entire storage rack is filled continuously.

At a first target location, transport pallets are then picked up and landed one after the other in a corresponding reverse order to a storage track.

If packaging to be transported directly to this destination type is to be included, which in turn is packed into large bundles on pallets, then by means of the transverse transport device at the end of the conveyor track remote from the lifting platform, each one is loaded onto a storage track in the unloading track. storage lane of full transport pallets (full packaging pallets) inserted and removed therefrom so that the target area of a storage lane is correspondingly cleared and can be filled in a corresponding manner with packaging. The process can thereby take place in such a way that each time after the removal of a "full package pallet" a "package pallet" is introduced via the lifting platform and placed on the desired storage track and subsequently a full package pallet can again be placed on the adjacent conveyor track. taken away.

In an embodiment of the invention it is provided that the conveyor tracks have at least two parallel transport carriers as longitudinal transport means, 1023472 · 4 each having an upwardly open slot, in which a drivable endless transport chain with its upper part is guided, which is supported by supporting elements for the transport palettes to be included is provided. By means of a longitudinal conveying means designed in such a manner, transport pallets can be placed close to each other, but also with spacing, on the storage tracks and be transported in the longitudinal direction of the conveyor tracks. By means of a corresponding drive that can be rotated in the direction of rotation for the endless conveyor chains, the transport pallets put away can optionally move in the one or in the other direction of the conveyor tracks.

Because the transport tracks are only formed by transport carriers arranged in parallel, there is a "filigree" structure of the entire storage rack with a relatively low own weight, which benefits the size of the useful load to be transported by the ship.

In a particularly effective embodiment of the invention, three transport carriers are each provided with an endless transport chain in each case. Thus, the possibility is offered that the transport pallets, in particular, for example, Euro pallets, are supported not only at the edges but also in the middle, and therefore deflection under load is excluded.

In an efficient embodiment of the invention, it is preferably provided that the drive of the endless conveyor chains is arranged at a distance relative to the end of a storage track in each case. This results in the advantage that each time at the end of the storage tracks for the endless conveyor chains with their support elements, only turning means need be provided and the drive is arranged in a region with distance thereto, preferably in a region in which the transport carriers are attached to a standing frame so that favorable mounting possibilities arise.

In an embodiment of the invention, it is furthermore provided that, as a transverse conveyor, at the end of conveyor tracks, a storage surface is arranged in each case between adjacent transport carrier, drivable roller bodies, the axis of rotation of which is directed parallel to the longitudinal axes of the transport carrier and which from a rest position below The elevation surface defined by the transport carrier can be lifted in a transport position above the elevation surface. It is thus possible to slide a transport pallet to be transported transversely to the storage track with the aid of longitudinal transport means from the transport carriers over the roll bodies, for example rollers, arranged between the transport carriers, so that the transport pallet is then raised above the upstanding surface and via the then entering driving the rolling bodies transversely of the storage tracks until a predetermined storage track can be moved adjacent to the storage surface. When the position of the transport pallet for the desired other storage track has been reached, the rolling bodies are moved downwards after the rotation drive has been switched off, so that the transport pallet stands on the guide carriers of the selected storage track and then via the longitudinal transport means in the direction on the lifting platform further to be transported. It is expedient here if the roller bodies associated with two adjacent storage tracks are movable up and down as a unit.

In an embodiment of the invention it is furthermore provided that movement elements are provided on the lifting platform for the one direction of movement, preferably for the movement in the longitudinal direction of the storage tracks, transport support elements with integrated drivable and endless conveyor chains, and for the roller bodies which can be driven transversely to this direction of movement are provided, the axis of rotation of which is directed parallel to the transport support elements and which can be lifted from the rest position below the elevation surface defined by the transport support elements into a transport position above the elevation surface. With such a lifting platform it is possible to pick up objects from a longitudinal side of a ship via the rolling bodies and to place them on the transport support elements after the rolling bodies have been lowered. The lifting platform can then be moved with respect to the desired storage track in the predetermined storage surface and the object can only be delivered from the lifting platform onto the transport carriers of the relevant storage track via the transport carrying elements. When an object is taken over, the lifting platform can be mounted on the transport carriers, the endless chains of the transport support elements of the lifting platform and the endless chains of the transport carriers are synchronously driven in the same way so that the object is immediately taken up by the storage track.

The receiving of an object from a storage track then takes place in the reverse direction, that is to say that the transport carrying elements of the lifting platform each receive the objects supplied by the transport carriers of the relevant storage track 25 until a predetermined position on the lifting platform is reached. The lifting platform is then moved to the longitudinal side of the ship and lowered and / or raised to the accommodation level of the loading quay, because after lifting via the driven rolling bodies of the object in question can be moved laterally so far outwards that it can be picked up by a ready fork lift device or a correspondingly positioned conveyor track.

In a further advantageous embodiment of the invention, a central control device with data storage is included, in which the relevant current position of an object in question is recorded on the storage tracks 5 and in which each removal and every access is recorded. The control device is advantageously designed in such a way that the drive of the lifting platform of the conveyor track, as well as the transverse conveyor device for the relevant access and the relevant removal of objects in terms of control are coupled to each other in the correct direction. Advantageously, in particular at the transition locations between lifting platform and transport carriers on the one hand and transprot carriers and transverse transport device on the other, corresponding sensors are arranged which are coupled to the control device in such a way that the individual objects are accurately recorded in position at least in a relevant transition area.

Figure 1 shows a perspective view of a cargo ship 1 for traffic on an inland waterway. Seen from the center of the ship 2, storage racks 2 and 3 are integrated in the cargo hold of the cargo ship, which, as will be explained below with reference to Figures 2,3 and 4, have three loading surfaces arranged one above the other. In the embodiments 2 shown here, each loading surface has storage tracks running side by side in the longitudinal direction 15 of the cargo ship, each of which is provided with the longitudinal transport means for transport pallets to be received. At the bow end 4 and at the hook end 5 of the two storage racks, the individual storage tracks of each loading surface are connected via a transverse conveying device 6 or 7 for converting objects, for example transport pallets, from a storage track to another storage track in the same plane.

In the midship, a loading and unloading device 8 is arranged at the other end of the two storage racks 2,3, which loading device is movable transversely to the storage tracks and which is provided with a lifting platform that can be moved up and down, which will be described below. has movement elements, as a result of which at least one transport pallet located on the lifting platform can optionally be displaced longitudinally of the storage tracks or transversely thereto.

As can be seen in Figure 2, in the exemplary embodiment shown, three loading surfaces 9.1, 9.2 and 9.3 are arranged one above the other.

As can be seen in figure 5, a total of four storage lanes 10.1.10.2.10.3 and 10.4 are provided in each of 5 loading surfaces 9.1,9.2 and 9.3. According to an illustration in figure 4, each storage track has three parallel transport carriers 11 which are provided with drivable longitudinal transport means. These longitudinal transport means can for instance be formed by endless chains mounted in the transport carriers, wherein the transport carriers each have an upwardly open slot in which the upper part of the drivable endless transport chain provided with support elements is guided.

The supporting elements arranged on the conveyor chain form a raised surface for the transport pallets to be received. For the sake of simplicity, only the relevant loading surfaces are shown in Figure 5. The relevant storage lanes are recognizable by the transport pallets 12 placed.

The loading and unloading device 8 is recognizable from the cross-sectional view of Figure 6. This essentially consists of a frame with two parallel, rigid guide frames 8.1 (Figure 1) fixedly connected to the ship's hull, between which a lifting platform 13 (Figure 1) extending above the height of the frame 25 is movable transversely. The lifting stage 13 shows a conveyor track 10 over its entire width, which width corresponds in each case to the width of a conveyor pallet in the given delivery position.

Arranged in the lifting platform 13 is a lifting platform 14 which is vertically movable via a drive motor 15 (Fig. 6), whereby each loading surface 9 can be reached via a limit switch control optionally by means of conventional lifting or lifting control.

With such a loading and unloading device it is possible to pick up transport pallets to be picked up from the quay wall on the lifting platform 14 and, by the respective transverse movement relative to the rack and the relevant lifting movement, to each time a predetermined storage track in a predetermined loading surface. to send. Via movement means to be explained in more detail below, the relevant transport pallet can then be delivered by the lifting platform onto the desired transport path of the predetermined loading surface. Accordingly, a transport palette can also be included by each storage track after a relevant control.

As can be seen from Figure 7 in the plan view, the lifting platform 14 arranged in the lifting platform 13 has transport carrier elements 16 arranged next to each other and which are constructed in a similar manner as the transport carriers 11 and which are each also provided with endless transport chains with those, which can optionally be driven in both directions via a central drive. A pallet placed on the lifting platform 14 can, when driven in the same sense of the transport carrier elements 16 and the transport element of the transport carrier 11, be taken up by the respective controlled storage track or taken from the relevant storage track.

Rolling bodies 17 are arranged in the space between the transport support elements 16, the pivot axes of which are designed parallel to the transport support elements 16 and which are each connected to a rotary drive. The rolling bodies 17 can be lifted from a rest position below the elevation surface defined by the transport support elements 16 in a transport condition above the elevation surface. It is thus possible to lift transport pallets standing on the transport support elements 16 of the transport support elements 16 and to move them transversely to the direction of the transport support elements on the lifting platform in the relevant direction of rotation of the drive of roller body 17.

Thus, it is possible to move a transport pallet 12 prepared by the loading dock, as shown in Figure 7, with the lifting platform 14 and to pull it onto the lifting platform after the rolling bodies 17 have been lifted. Subsequently, the rolling bodies 17 are moved downwards so that the picked-up transport pallets, as described above, can be supplied to a selected conveyor track in a predetermined loading surface and can be pushed onto it.

In a storage rack thus fully filled in the manner described above, the transport pallets can then be removed from each storage track of a loading surface.

As has been described for the preferred case of transport of beverage crates that have converged on transport pallets to form a large bundle, not only must the "full stuff" be transported from the initial location to the final location, but also "packaging" must be transported to the initial location transported back. Thus a discharge process for the "full stuff" is created at the respective ends as well as a loading process for the "packaging". In order to be able to combine these processes with each other, two storage tracks are coupled to each other in each loading surface such that after full loading at the starting location on a storage track the "full stuff" can be removed and in the associated adjacent storage track the "empty stuff" ( packaging) "30 can be placed. In order to make this possible, a cross transport device 6 or 7 is arranged at the end 4 or 5 of each storage rack 2 or 3 remote from the loading and unloading device 8.

T0I3472 · 12

This essentially consists of at least one drivable roller body 18 arranged between neighboring transport carriers 11, as shown in Figure 8, the axis of rotation of which is directed parallel to the longitudinal axes of the transport carriers 11 and which, as is already the case for the loading and unloading device 8 is described with reference to Figure 7 from a rest position below the elevation surface defined by the transport carriers 11 in a transport position above the elevation surface. It is thus possible to slide the longitudinal conveyor means, for example, from the storage track 10.1 in the direction to the cross conveyor device 6 and 7 arranged at the end, while the storage tracks 10.1 arranged parallel thereto are driven in the direction to the loading and unloading device 8. Via transverse transport an incoming transport pallet can then be received at the end of the storage track 10, transported transversely and delivered to the neighboring storage track 10.2. The conversion from one storage track to the other storage track takes place in accordance with the inclusion of "full stuff", preferably of storage track 10.2, wherein a corresponding location on the corresponding storage track 10.1 is then released at the transition location of the loading and unloading device 8, on which a package palette can then be put away.

Control of the loading and unloading device 8, the transverse conveying device 6 and 7 as well as the longitudinal conveying means of a separate loading surface can then be coupled to each other via a central control device, whereby the occupation of the storage tracks can be determined with transport palettes via an associated data storage and thus "storage accounting" for the storage rack integrated into the cargo ship is possible.

1023472 · 13

With the aid of such a control device it is also possible to pre-program deliveries for individual end locations, so that a precise mooring is possible with regard to the piece numbers to be supplied. In accordance with the predetermined construction, a corresponding quantity of packaging can therefore be taken up again at each end location. Via correspondingly arranged position sensors and so-called locks of the mutually coupled drive of separate moving and transporting means, it is ensured that the individual transport palettes move piece by piece in the storage rack and can, if necessary, also be converted and finally landed and / or can be included.

The transverse conveying device 6 or 7, respectively, at the end of a loading surface on the one hand and the transverse displaceability of the loading and unloading device 8, respectively, over the entire rack width makes optimum and efficient utilization of the available storage space possible.
