[0001] The present invention relates to a device for removing coupling pieces from containers.
Transport containers which are stacked on top of one another are connected to one
another by means of securing bars, which are attached crosswise along the short sides
of the containers and by means of coupling pieces, which are introduced into holes
in the region of the corners of the containers. The coupling pieces may be of semiautomatic
design and when the containers are stacked can be pressed into the locked position.
The wide variety of coupling pieces means that they are removed manually when unloading
the containers. During this operation, in order to protect the operator who is removing
the coupling pieces, a safety cage is used, having the same dimensions as the containers,
with holes cut out of a base plate in the region of the corners. When the safety cage
has been placed on a container, the coupling pieces can be removed via the holes in
the base plate without there being any possibility of the operator falling off the
stacked containers. The safety cage is moved along each time by means of a lifting
device.
[0002] This method of removing the coupling pieces is relatively laborious and slow. Furthermore,
the use of a large safety cage is very expensive. It is an object of the present invention
to provide a simple device for removing coupling pieces while ensuring the safety
of the operator at all times.
[0003] To this end, the device for removing coupling pieces from containers according to
the present invention is characterized in that the device comprises a carrier with
two longitudinal sides and two transverse sides, an enclosure being suspended from
at least one transverse side, the said enclosure having side walls which, on the front
side, which is directed towards the centre of the carrier, of the enclosure, are no
higher than 1.5 m, and the enclosure being provided with at least one partition which
divides the enclosure into at least two compartments.
[0004] The operator can take position in the enclosure, which by positioning the carrier
above the container, can then be moved so that its front side is at the level of the
container edge. After this, the operator can remove the coupling pieces and place
them in the collection compartment of the enclosure. As a result, the chamber for
the operator remains free of coupling pieces at all times, so that the operator cannot
injure him/herself on the said coupling pieces. By moving the carrier, including the
enclosure and the operator, along a series of stacked containers, the coupling pieces
can be removed quickly and safely. In the process, the operator can continue to stand
upright without having to bend over, thus maintaining an ergonomically sound working
situation.
[0005] Preferably, the carrier is adjustable in terms of length in the direction of the
longitudinal side, so that it can be used for containers of different lengths, such
as for example 20, 40 or 45 feet. Preferably, the enclosure is provided on one side
with a closeable access door, so that the operator cannot fall out of the enclosure.
Preferably, a sloping roof is arranged above the enclosure, so that the operator is
protected from effects of the environment. Furthermore, a protection may be arranged
in the form of side walls of the enclosure.
[0006] Preferably, the enclosure is detachably coupled to the carrier, so that the carrier
can also be employed for other purposes, such as for example lifting up separate containers.
[0007] One embodiment of the device according to the present invention will be explained
in more detail with reference to the appended drawing, in which:
Figure 1 shows a perspective illustration of a device according to the present invention
provided with two enclosures, and
Figure 2 shows a partial side view of the device in accordance with Figure 1 in the
operating position.
[0008] Figure 1 shows a device 1 according to the present invention with a carrier 2, from
which two enclosures 3, 4 are suspended. Via cables 5, the carrier 2 is attached to
a lifting device (not shown in the figure) and comprises longitudinal sides 6, 6'
and transverse sides 7, 7' . The enclosures 3, 4 are suspended from the transverse
sides 7, 7' by means of four bars 8, 8' . Each enclosure is provided with a front
side 9, 9' and a rear side 10, 10' . At least the front side 9, 9' is of a height
which is such that it reaches no further than the waist of an operator of average
height. The rear side 10, 10' is provided with a closeable access door 11. The enclosures
3, 4 are divided, by means of two partitions 12, 13, into three separate compartments.
The operator can take position in the central compartment, while the removed coupling
pieces can be collected in the side compartments. As can be seen from Figure 2, by
positioning the carrier 2 above a container 15, the enclosure 3 can be placed at the
correct height with respect to the top side of the container. As a result, the operator
can remove the coupling pieces in the region of the corners 16 of the container 15
without having to bend over. As is illustrated diagrammatically in Figure 2, the carrier
includes two longitudinal arms 17 which, by means of a hydraulic device (not shown
in the figure), can be adjusted in terms of length with respect to the stationary
central part of the carrier, so as to be adapted to the dimensions of different containers.
[0009] As shown in Figures 1 and 2, each enclosure 3, 4 comprises a sloping roof 18, with
the result that the operator is protected from weather influences, such as precipitation.
Furthermore, the side walls and the rear wall of the enclosures 3, 4 may also be provided,
for example, with transparent plastic panels providing further protection for the
operator against weather conditions.
