Description

Load handling system

The present invention relates to a load handling system comprising a plurality of load carriers, such as 5 RoRo, terminal, industrial cartridges and / or the like, and one or more traction sheaves or AGVs with or without a lifting tail. The system is intended for unloading a load such as containers or the like in a container port or similar vessel, for further unloading from the pallets moved to the unloading station for further processing and for reloading the empty pallets transferred to the loading station. or the like for loading an outgoing vessel.

For the purpose described above, for example, in ports or in industrial environments, it is currently known to use diesel-powered propulsion units, which are either integrated or manually controlled, so-called "lifting gears", for cost-saving reasons. AGV (Automatic Guided Vehicle) drive units or with fifth wheel hitch arrangement for attachment to separate lifting trolleys.

Such lifting conveyors typically include hydrostatic actuators for lifting the load on the lifting tail or wagon. The actuators are typically actuators, such as hydraulic cylinders for changing the ground clearance of the lifting gear or trolley, on the wheel arrangement of the nos-30 transporter and / or the articulated arrangement on the drawbar of the separate traction unit, such as hydraulic cylinders.

The trucks, on the other hand, have so-called. below tunnels into which the lifting platform or wagon can be lowered. The tunnel height 35 2 on the load carrier depends on the type of cassette used in each case, thus minimizing the tunnel height of the cassettes used especially in shipping operations. Figure 2a shows a typical load carrier with dimensions depending on the application typically within the following limits: - Li: 2133 mm - 2700 mm - L2: 2359 mm - 3000 mm - a: 50 ° - 60 ° and 10 - h: 703mm - 1000mm.

On the other hand, as shown in Fig. 2b, it is of course also possible to utilize a wheeled load carrier.

At present, the above-described arrangements still have environmental disadvantages due to the diesel operation, and in addition the power supply of the drive unit must always be dimensioned especially for the lifting and transfer functions of the respective load 20. Thus, when a drive unit with a lifting gear or attached to a lifting carriage moves unloaded, there is a constant excess of mass. Therefore, the energy capacity of such a continuous transport vehicle 25, which is constantly present, should be dimensioned in the light of the total energy consumption of its respective operating cycle, which would require, in particular, an electronically implemented currently disproportionately large battery.

The purpose of the system of the present invention is to provide a decisive improvement on the above-mentioned problems and thereby substantially increase the state of the art. To accomplish this purpose, the system of the invention is essentially characterized in that the truck included is provided with an energy storage device, such as a battery, supercapacitor, and specially designed for operations performed with a loaded lifting trolley or trolley or an AGV device. or the like, in particular to enable lifting transport equipment 5 to be used electrically or electro-hydraulically.

The most important advantages of the system according to the invention are the simplicity and efficiency of the constructions and its use, which can significantly reduce environmental damage and energy consumption and significantly improve load handling eg in port or terminal use etc. The system according to the invention -15 hydraulically operated without the need for internal combustion engine solutions. Thanks to the invention, it is possible to further minimize the energy consumption of the unloaded lifting gear, since the invention enables the drive unit to be advantageously provided, for example, with a dimensioned battery and / or a supercapacitor arrangement for transmission only when unloaded.

Other advantageous applications of the system according to the invention are disclosed in the dependent claims.

In the following description, the invention will be illustrated in detail with reference to the accompanying drawings 30, in which Figure 1 illustrates a preferred operating principle of the system of the invention 35 particularly in a container port or similar utilization; Fig. 3 shows some of the preferred draw gear and load carrier used in the system according to the invention.

Further, with particular reference to Fig. 1, a charging arrangement 6 is provided for the unloading station I, the loading station II and / or another handling unit for the loading platform for loading at least the energy storage 3 25 in the loading platform 1, such as a guide arrangement 6a.

via contact surfaces 6b in the substrate. In this connection, it is still advantageous to also connect the charging of the basic energy storage 4 of the drive device 2 with it or the nos-30 transport trolley connected thereto in the unloading station I

and / or the charging arrangement 6 in the loading station II; 6a. It is also possible to include in the system its own charging station for the traction device, where the traction device can be recharged when the charge of its basic energy storage 35 drops below the allowed point.

Thus, for example, the automatic AGV device 2 shown in Figure 3 or the cab drawer 2 shown in Figure 2b 6 is preferably provided with monitoring means for monitoring the status of the basic energy storage 4 and the lifting transporter or carriage 2a.

As a further preferred embodiment, with particular reference to Fig. 3, the coupling members 5 are arranged between the load carrier 1 and the lifting gear, carriage 2a or AGV device, which automatically connect the electrical circuits of the base energy storage 4 and energy storage 3 to the load carrier. for a trolley or AG ν 'devices on the road. In this connection, it is still possible to arrange the carrier 1 and the lifting platform, the carriage 2a 15 or the AGV device by electrically contactless means, for example by inductive or capacitive arrangements.
