DESCRIPTION:
BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a national phase of PCT/EP93/02611 file 25 September 1993 and based, in turn, upon German national application P 42 33 007.6 filed 10 October 1992 under the International Convention.
FIELD OF THE INVENTION
The invention relates to a process for the transloading of loaded goods units such as containers, interchangeable containers, semi-trailers or the like by means of transloading lifting gear (so-called rendezvous technology) from or onto a slowly travelling train formed by container cars as well as to a means for carrying out the process, comprising a rail system including at least one track, a store complex comprising a store internal transport system and transloading lifting gear extending to the rail system and the store internal transport system.
A process and a means of the aforesaid type have already been proposed. If a train travels from locality A to locality Z by way of the localities B, C, . . ., it is usual for only part of the loaded goods units to be unloaded at the localities B, C, . . . The loading capacities of the container cars of the train which are already free or are rendered free as aforesaid, may be used to receive other loaded goods units.
When transloading from or onto moving container cars it stands to reason that--even in the event of low (crawling) velocities--considerable problems arise in the reliable picking up or the setting down of the loading units rapidly. If from a section of the train only a small proportion of the loaded goods units is unloaded it is possible, in view of the capacity of the transloading lifting gear, for the train to travel at an appropriate velocity. If, on the other hand, a major proportion of loaded goods units is to be unloaded from the next following train section, the train, because of the available transloading capacity, must be moved correspondingly slowly. Due to the brake applications necessitated thereby and the resultant resiliency effect of the train (sprung traction and pushing means between the individual cars) there result timber uncertainty factors and difficulties when picking up (gripping) the loaded goods units to be unloaded or when putting down the loaded goods units to be loaded onto the train:
A need exists to so improve the process of the aforesaid type and a means for carrying out the process, that the transloading of the loaded goods units can be accelerated and rendered more reliable.
OBJECT OF THE INVENTION
It is, therefore, the object of this invention to provide an improved process for transferring load units to and from a train as well as to provide apparatus for carrying out the improved process.
SUMMARY OF THE INVENTION
The present invention provides a process wherein initially each container car to be unloaded and/or loaded has assigned thereto a reference or measuring point, the position of which, being variable in space in terms of absolute time, is continuously measured in relation to a fixed measuring section, whereafter there is measured in relation to the fixed measuring section, and defined as a differential distance in relation to the reference point: the rail longitudinal direction, is likewise variable of at least one load attack point or a gripping position of the loaded goods unit, e.g. the corner recesses (corner castings) of containers and variable in time in the longitudinal direction of the rails, of the receiving or locating pins of the container car, locating pins in relation to the reference point is determined, the position of the center of the load receiving points of the associated transloading lifting gear is continuously measured in relation to the fixed measured section, and the transloading lifting gear is moved so that the load receiving center coincides with the center of the load attack points or the receiving elements.
The basic concept of the invention resides in that the position of the load attack points of the loaded goods units which varies with time prior to their being picked up (gripped) respectively of the loc
