BRIEF SUMMARY
SPECIFICATION
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a National Phase application of PCT/EP94/03772 filed 14 Nov. 1994 and based upon German application CH-3507/93-0 filed 24 Nov. 1993 under the International Convention.
1. Field of the Invention
The invention relates to a rail-type conveyor system.
2. Background of the Invention
Rail-type conveyor systems have been known from Swiss patent 496 603. This conveyor system contains transmitting and receiving stations, in which the conveyor trucks are manually loaded at the transmitting stations, provided with a destination code and despatched. At the receiving station the conveyor trucks again have to be unloaded manually and either reloaded or despatched empty to a collecting station. Thus, an operator is always necessary for loading and unloading and if no such person is available the conveyor truck has to wait at the station and is unavailable for further use. However, waiting conveyor trucks may also block the station by indicating that they are occupied and thus preventing further conveyor trucks from entering.
From German patent 24 47 294 a similar conveyor system for documents is known which overcomes the disadvantages described above by having loading means arranged above the stations for placing material in the conveyor trucks. For unloading, the containers of the conveyor trucks are fitted with floor-mounted flaps which, on opening, deliver the material into receptacles provided at the stations. However, a disadvantage of this is that the containers cannot be mounted above the drive mechanisms of the conveyor trucks but have to be positioned to one side so that the floor-mounted flap is unobstructed. This results in a complicated construction which leads to an asymmetric and therefore unfavourable distribution of forces owing to the one sided arrangement of the container on the chassis and requires a wide-gauge track.
OBJECT OF THE INVENTION
The goal of the invention is to improve a rail-type conveyor system of the kind described hereinbefore so as to avoid the disadvantages outlined above.
SUMMARY OF THE INVENTION
This aim is achieved by providing a rail-type conveyor system having despatching and receiving stations and with self propelling container trucks. The container trucks have unlockable loading and/or unloading means and the despatching and/or receiving stations have at least one stopping point with delivery and/or receiving means for automatic loading and/or unloading. Each stopping point of the receiving station has a rail section corresponding substantially to the length of the container truck with rail portions which engage with a C-shape around the side of the track wheels of the container truck. The rail section is pivotably mounted on a longitudinal side, towards the unloading side, about a pivot axis so that the unloading means can be opened towards receiving means.
By the pivoting of the rail section and hence of the container truck located thereon, this truck is brought into an inclined position which causes it to empty its load. As a result, the container truck can be mounted directly over the truck in the usual way, thereby bringing about the known symmetrical construction which ensures a uniform distribution of forces. This simplifies the structure. In particular, this allows a narrow construction, so that the space taken up by the track can be kept to a minimum.
There are numerous possible methods of initiating the pivoting movement. For instance, the pivoting movement is initiated by the drive of the truck itself, which means that no additional drive is required. Another method of pivoting the rail section is to provide the station with an additional electric drive motor. One particularly simple solution is the container truck which is in motion can drive the pivoting apparatus.
The lifting member necessary for raising or pivoting the rail section may also take various forms such as a cam or a rack or a pivot lever.
The unloading means of the container trucks may take a very wide variety of forms
