Positioned and then inclined to its open side against the gate, which is initially arranged so that it closes the open side with the exception of its upper part. The gate is then moved towards the loading area of the container lowered so that a successive unloading of the container is possible, with its contents successively on one Slide is brought. This is connected to the oatter and directs the container load to suitable means of transport. The empty container is then returned to the upright position and removed from the reloading device.

In a second embodiment according to the invention, the hatter and the channel or chute form part of the reloading device and are inclined with the container into the unloading position. The container is then up on the gate moved past, so that a controlled unloading of the container * · contents takes place. The empty container is then lowered into the brought upright position and then removed from the reloading device.

In a third embodiment of the invention, the gate is part of the reloading device and is with the container brought into the inclined position, at the same time in contact with the chute; the container is then placed in the inclined position, as in the previous embodiment, raised.

In a further advantageous embodiment of the invention, means are provided that the container both after the open Tilt side as well as to one end. In this way, the successive areas of the container are unloaded with allows greater control, especially when the container is is divided into several compartments. The container can hori < zontally divided into two or more compartments, these in turn can be divided vertically into two arrangements of compartments or parts,

which are arranged back to back, are divided. In a corresponding manner, as described above, each container only tilted to one side and then to the other open side, with a gate being provided in each case, the one in the above described way works,

According to an advantageous further development of the invention, that is Gate arranged in such a way that, as a whole, it executes a movement directed from bottom to top with respect to the container. '

In yet another embodiment of the invention, there is Gate from a conveyor belt with rollers without their own drive, which are mounted in sliding guides, a part of which has a surface that of the flanks of the container | corresponds and consequently in one position the whole Container flank or hand covers. During unloading, the two rollers are moved together over the edge of the container out, successively releasing the container partially until the conveyor belt is completely moved to one side that the entire side of the container and on this catfish total unloading allowed. Such an arrangement eliminates any possibility of wear or damage to objects in the container that could occur as a result of jamming or friction due to contact with the oatter.

The invention allows rapid unloading of, for example Baggage from such containers with simple means and a supply of this baggage to one or more distribution, Sorting or collecting points with a minimum of difficulty.

Further advantages and features of the invention are based on FIG Embodiments explained in more detail according to the drawing. It shows:

As soon as the container is brought into its position on the frame 5, it borders on a gate 9 * which initially the lower part the open side of the container completes until the container and the gate from the upright position, as shown in Fig. 3, are brought into the inclined position, namely in the unloading position of the container.

The gate 9 has two racks Io · As soon as the gate is in the inclined position, it will be open with respect to the adjoining Side of the container lowered by means of drive wheels 11, | These are driven by an electric motor 12 and are in engagement with the racks Io, so that successive unloading of the successive sections of the container takes place in accordance with the lowered gate 9.

Pig.5 shows a container on the frame 5 of the reloading device, namely before this device is in its tilted position was brought. For these reasons the gate 9 is in its highest position Channel or slide I3, which the gate 9 allowed through Goods to a conveyor belt 14 leads. Its rear end is supported in guide parts 15 which are attached to the gate 9. The conveyor belt is driven on its front by a 16 "motor driven. The channel IjJ can be made entirely from fixed individual parts exist. In a further embodiment, the bottom of the channel can have any type of conveyor belt, for example a driven belt or a belt or of several parallel ones optionally driven rollers exist. This arrangement reduces or even avoids the friction between the Channel and the goods that are allowed through the gate on their way to the unloading and distribution points.

Pig. J brought position shown, the trolley 3 is with the drive chains 2 engaged and out of the reloading device brought, with the next container and its trolley being fed to the frame 5 at the same time. To the Control of the entry and exit of the containers will be the Trolleys 3 guided between rollers 19, which in turn in Rails 2o are stored.

As can be seen from FIGS. 6 to Io, the container in relation on the gate and the gutter are raised, the gate and the channel form part of the frame itself on which the container rests during the unloading process.

As shown in FIGS. 6 and 7, the container is placed in the | and from the transfer device by means of driven rollers 22 in the input and output part of the belt 21 as well as in the central area 23, which is part of the reloading device, brought. Once the filled container in the central section 23 of the belt 21 is brought, the container of a frame 24 sandwiched between two inclined parallel rails 25 is arranged, worn. The part 23 of the transport device has a plate 26 arranged on the rear side for support. This plate 26 is together with the central Part 23 and the frame 24 arranged so that they are around pegs 27 Can be pivoted until the plate 26 is in engagement with the rails 25, the tilting with hydraulic or pneumatic Lifting devices 28 is completed. The plate 26 carries * Pads filling the gaps between the inclined rails 25; these rails' serve as guide rails for the container during the unloading process.

The plate 26 carries a gate 29, which is attached to the adjacent open side of the container joins the frame 24; Farther is a gutter 23 »connected to it, with the gate with

-8- ■ ■

009839/1456

its upper edge is inclined at an acute angle to the horizontal in order to ensure a partial unloading of the container.

As soon as the parts 23 and 24 with the loaded container are pivoted in order to bring the plate 26 into engagement around the inclined rails 25, the frame 24 rests on rollers 30 which are guided by the rails 25; the frame with the tilted container is raised to the level of the inclined rail 25 by means of winches J> 1 , which are driven by a motor 32, the frame being connected to this via cable 35.

In this way, the tilted gate 29 and the channel 33 remain stationary, while the container and the frame 24 upwards behind the inclined gate slide so that the contents of the container onto a channel or chute 33 and from there onto a conveyor belt 34 is discharged. As soon as the container is emptied, it will lowered on the Oestell until it rests on the central part of the conveyor belt, which then together with the gate 29 and the channel 33 in the upright position shown in FIG is brought, from which the empty container is removed and a loaded one is fed to the reloading device, this Movements can be controlled by means of contact contacts or limit switches 26.

The embodiment shown in FIGS. 11 to 14 corresponds to that in FIGS. 6 to Io with the difference that the channel 23 is connected to the reloading device in the tilted position and in this way forms part of the frame holding the scaffolding, which also includes the inclined rails 25. As soon as the loaded container or the central part 23 is in contact with the frame 24 and the gate 29 and is tilted around the pin 27 by means of the lifting device 28, the frame is arranged with its rear side. plate 26 and the gate 29 in that position, jai start of the unloading

can, brought. The container is on its frame 24 on the inclined rails 25 by means of motor-driven winches ^ l and -the cable 55 is raised while the gate 29 is in its original Location and remains connected to the fixed channel 33.

The central part 23 of the transport part 1 is in this embodiment also pivotable at one end, namely transversely to the center line of the transport part, as can be seen from Fig. 14, can a container by means of a lifting device 37 and a linkage 38 can be raised at one end while he is pushed onto the rails 25. This measure causes a more effective control of the unloading process from each compartment of the Containers. A spring-loaded back stop 39 is in this embodiment also provided to the degree | to limit tilting in the longitudinal direction and to prevent slipping of the container from the framework 24.

The exemplary embodiments described above relate to a container that is emptied on one open side. As already mentioned above, however, a second unloading device be provided for emptying the opposite side of the container, the container having a central vertical wall has for subdivision, in addition to or instead of the horizontal frame or. Insoles.

The conveyor devices or conveyor belts 14 and '34 can to any suitable unloading, splitting or distribution unit ™ direction, e.g. to a circular conveyor with changeable Inclination or another appropriately controlled output device.

As can be seen from FIG. 15, the conveyor device 14 can be arranged in such a way that, instead of the conveyor devices or conveyor belts 17 or ~ $ K , it feeds the goods to an intermediate conveyor belt 141 which transfers its load to a customer.

band 142 leads, which in this embodiment is an inclined Band is «that is arranged at right angles to the intermediate band and, for example, at an angle to it is inclined by 40 °.

In the present exemplary embodiment, the conveyor belts or conveyor devices 14 and 141 have a width of up to approximately 2.5 m (8 feet) dnd one independent or one common Two speed drive on while the doffer belt 122 is approximately 1.25 m (4 feet) wide. The conveyor belt 141 can either be used as a continuous feeder for the belt 142, or it can serve as a storage or stacker. It can also be operated in such a way that it is suitable for a uniform supply of material to the belt 142 ensures. The unloading process typically consists of five stages:

a) the reloading device tilts the container with or against the gate,

b) the goods in the container are unloaded with the aid of the gate,

c) after a dwell time, the content reaches the first of the unloading belts,

d) the container is in the upright position; f its Brought transport device or its conveyor belt,

e) the container is removed from the reloading device and a new container is placed on the scaffolding.

These individual sections are carried out in the following order :

009839 / U56

Once the container reaches its initial tilted position has, the conveyors or conveyor belts 14 begin, 17 »34, 141 and 142 at their specified speeds to run. A timer monitors the conveyor belts as they run until a good arrives from the container to the customer conveyor belt is, wherein the transport speed is such that correct feeding of the goods to the last transport device or «conveyor belt is guaranteed. In a particular embodiment, three container racks with about 1> 5 ra width of your entire content on approximately 6 m of the conveyor belt, this at a speed of about 6.5 m / min. runs, submit. That means, for example, goods to the

According to this example, luggage can be attached to belt 142 in a period of 24 seconds. are supplied with an adjustable temporal distance of about 8 seconds. between each Containers. (The transport devices or belts can move in the other unloading sections at a lower speed

to run)

In a further embodiment of the invention, the containers sliding walls around the otherwise open side or open Sides are arranged so that they can be moved vertically and / or horizontally, each side in a preferred embodiment has two such walls.

By appropriately programming the control for both the vertical and the horizontal ones Each container can have walls, starting in the upper left corner of the container side, for example be discharged, in any given sequence, being a coordination of the relative movements between the tilted Container and the adjacent, i.e. assigned gate, is possible.

-12-

009839 / U56

If the direction of displacement of one or both rare walls is reversible, the number of possible discharge sequences is still greater. If the directions of displacement of the two side walls are reversible, then unloading can take place at one of the four corners of the Begin on the container side. A practically unlimited number of unloading sequences is possible through predetermined opening and closing « A special sequence can be programmed so that consecutive containers each have a different sequence can be discharged.

The consequences of the loading processes can be coded for each container at its starting point, for example as soon as the container in question Container and its flight plan are available, then this information can be used be transmitted by means of a computer to the arrival point (s) on its route, the computer providing the exact Identification and unloading sequence of the containers programmed at their destinations.

By properly coding the containers and their cargo, their cargo can be unloaded accurately and even to different ones Unloading stations or warehouses are brought, all of these Processes are already determined before the freight has left its starting point. Changes due to delays in Traffic or route changes can easily be taken into account by the computer without the optimal unloading operation memorial book is influenced.

In a modified form for this control of the unloading process the container, each sliding side wall is in turn divided into individual sections that can be operated independently of one another * can be made.

Each sliding side wall can be horizontally or vertically divided into a number of independently sliding walls

Q09839 / U56

which, as in the previous example, are divided into can be shifted in one direction or reversibly.

These side walls and their subdivisions can be made with a single drive mechanism, for example by suitable means, shifted ', such as clutches, with each clutch only is engaged then and only as long as it is necessary. The clutches or claws can either be used individually or in groups driven by two or more; it lies on the hand that all claws or couplings at the same time can be operated. .

The side walls can be arranged vertically and / or horizontally so that a large number of Entlademög- | Handle is required. These side walls or their sections also need not all be of the same order of magnitude. One any combination of dimensions of these side walls is possible. The displacement of these side walls and their parts is controlled by suitable means, such as the computer system described above or by means of punch cards or punched strips. The settlement system outlined above allows one separate handling of the transport of goods, for example luggage in small quantities, with favorable supervision of the Handling of the transport.

The traveler can receive a baggage card with the container number and the number of the subdivision; this information will be available at the departure airport entered into the computer by passenger handling. The computer for its part works out an issue card for the delivery of the luggage to the traveler until his arrival.

The device according to the invention is particularly suitable for Handling of flight baggage, especially in the case of large-capacity aircraft with a large load capacity, which have the baggage in their hold or have stowed commercial goods in containers. The con-

talner are handled mechanically and are, for example, through Colors marked to allow accurate unloading. Discharge speed and discharge efficiency are of the utmost importance to get the aircraft ready for take-off again to get. Just as important is the handling of arriving travelers and their luggage at the airport as little as possible Expenditure of time.

The invention is not limited to the exemplary embodiments shown and described; it also includes all partial and Sub-combinations of the features described and / or shown.
