Description

CONTAINER UNLOADING SYSTEM

The invention relates to a system for unloading discrete containers to be dumped from a wagon, in particular a railway wagon, wherein the carrier surface of the wagon is adapted to carry each container and comprises means for furnishing the container during partially under the container, the means including lifting arms adapted to tilt the container and holding means for holding the container on the lifting arms.

BACKGROUND OF THE INVENTION US Patent 5,685,454 discloses a system for emptying a rack-mounted sack container. Here, the bottom of the frame is tilted and, while the mouth located at the bottom of the bag is poured downwards, the material flows out of the opening of the bag. U.S. Pat. No. 6,835,041 B1 discloses a system in which containers are tilted with a special auxiliary device whereby the material flows out of the side door. In addition, a plurality of devices are known for inverting a container such as, for example, U.S. Patent Nos. 5,558,485 and 6,394,736.

In addition, a plurality of wagons fitted with tilting pallets are known, such as, for example, US6,192,804. The load flows δ ^ either too close to the track or the auxiliary guide takes it so low, c \ j,,,, Ί Y, that a special embedded melting solution is needed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a simpler logistical system that can be easily adapted, for example, to train wagons or wheelchairs. Characteristic features of this invention are apparent from the appended claim 1.

The tilt does not want to lose the lifting height or drain 10 materials onto the track or similar cycle line. The system according to the invention employs a separate auxiliary device, which, like forks, is placed under the container and can be moved slightly sideways before the goods are dumped out of the container. Thus, in the system of the invention, containers 15, freight wagons and a tipping device are fitted together. The tipping device is preferably provided with a quick attachment and is operated by a conventional work machine, for example a wheel loader. An advantage of the system according to the invention is that the relatively light weight unloading device can handle heavy loads 20, on the support surface of the wagon. There is hardly any load on the machine. Even the lightest machine acts as a sufficient counterweight. Preferably, the unloading device has an auxiliary arm which moves the load space laterally away from the carriage.

In the following, the invention will be described with reference to the accompanying drawings, in which: o, Figure 1 shows the unloading device in a rest position on a train C \ 1 V Figure 2 shows the unloading device in a rest position as an axonometric view of σ> °

The bearing surface 32 is particularly relevant to the present invention since a heavy device can be used to carry a heavy load, so that the attachment means 16 of the work machine to be secured need not be large. The unloading device 10 20 comprises a body 14 having fork arms 12 and said body having said fastening stop 16 for a work machine. Hydraulic power is obtained from the implement in a known manner. Figure 2 shows the machine in a resting position, resembling a fork lift.

Inside the fork arms 12 there are lifting fork arms 24 which are o, 25 secured to the body part 22 by means of a front auxiliary arm (25).

The auxiliary arm 25 connects the body fork arm 12 to the front end of the joint 26 and the lift arm 24 to the front end of the joint 27, at the same location also the upper end of the auxiliary cylinder 23 and the other end is hinged on the body fork arm. The upper end 5 of the lifting arm 24 has a joint 31 which is actuated by a telescopic cylinder 20 and is articulated to a joint 29 at the body end of the fork arm. It is essential that the container must be somehow attached to the lift arms. In this case, a container lock 18 is used to hold the container 36 on the lifting arms 24 when tilted. The device 10 includes suitable means for opening the door 37, which is shown below.

Figure 4 clearly shows the configuration of the device having two forks with a fork (frame 14 and arms 12) and a lifting hook 15 with a fork 24 having a binding frame 24 thereon.

Returning to Fig. 3, it should be noted that in the initial phase of the lifting operation, the lifting cylinder 20 must first be lifted when moving from Fig. 1 so that the auxiliary cylinder 23 has a slight force-20 arm, after which this lever is increased when

The delta view of Figure 5 shows the hinge of the door. The hatch latch mechanism includes a load compartment shaft 39 which uses latch 38 to lock the hatch, Fig. 6. The latch moves in its axial rotation to close the slit hatch when the latch is turned upright (not shown).

CM

The system according to the invention thus utilizes matched containers with suitable fastening means 5 and transport means such as train wagons and a special unloading device in the unloading area for tilting the unloading containers to unload material therefrom. The components of the system are described above in a rather simplified manner. From the system point of view 5, it is essential that the unloading device can be pushed under the containers in the unloading situation whereby the support surface of the wagon can be utilized and raised on the rear corner of the container to furnish the container. The machine does not need to lift the entire container to the air, whereby the machine can be quite light and sufficient to handle the unloader free. The invention further enables the material material to be distributed a little further away from the wagon, which is a considerable advantage when unloading large quantities.

SUMMARY OF THE NEW SYSTEM

The transportation system is based on the use of the new types of cargo and unloader described in greater detail above.

Among the new advantages of the system over the existing systems are: the much better use of existing transport equipment, e.g. numerous landings.

Possibility of using a new type of demolition equipment on existing machines, such as those used in Finland, for example, more than 10,000 ^, the quick attachment of the demolition equipment enables the machine to be used ^ for other work as well.
