Abstract
An apparatus is disclosed for transporting loads of the type comprising self-propelled carriages movable on rails and having assembly structure on which removable containers may be engaged and temporarily fixed, loading and unloading of such containers taking place in automatic loading and/or unloading stations. The assembly structure contains at least one assembly profile oriented parallel to the axis of movement of the carriage and cooperating with a corresponding assembly profile provided on the containers, so that the assembly or disassembly of the containers may take place after a relative carriage/container translational movement parallel to said axis of movement.
Claims13
Apparatus for transporting light loads in the range of 10 to 15 kg comprising:
- at least one self-propelled carriage having a longitudinal axis and movable on rails along said axis, said rails having horizontal and vertical portions, said carriage being provided with a first assembly profile oriented parallel to said axis and with first locking means;
- at least one removable container having a hollow body and a cover which is hinged on a lateral face of said body about a pivoting axis, said container having a second assembly profile formed both on said body and on said cover and oriented at right angles with said pivoting axis, and shaped so as to be slidingly assembled with said first assembly profile once placed in an assembly position by effecting a relative translational displacement of said carriage with respect to said container along said longitudinal axis on a loading portion of said rail, said removable container further having first and second bearing surfaces respectively formed on said body and on said cover and oriented at right angles with said pivoting axis, and second locking means which cooperate with said first locking means so as to provide a rigid attachment between said carriage and said container once assembled;
- at least one loading station comprising means for placing and retaining said container in front of said loading portion in said assembly position;
- at least one unloading station comprising an unloading portion of rail, holding means for retaining said container while being transported by said carriage on said unloading portion, two parallel conveyors disposed in front of said unloading portion and under said bearing surfaces when said carriage provided with said container is in said unloading portion so as to allow disassembling of said container from said carriage according to an unloading sequence comprising an unlocking step of said locking means, a translational displacement of said carriage while said container is retained by said holding means and a conveying step of said container of said conveyor once said container is disengaged from said carriage.

Apparatus for transporting loads comprising:
- at least one self-propelled carriage having a longitudinal axis and movable on rails along said axis, said carriage being provided with a first assembly profile oriented parallel to said axis and with first locking means;
- at least one removable container having a second assembly profile shaped so as to be slidingly assembled with said first assembly profile once placed in an assembly position by effecting a relative translational displacement of said carriage with respect to said container along said longitudinal axis on a loading portion of said rail, said removable container further having second locking means which cooperate with said first locking means so as to provide a rigid attachment between said carriage and said container once assembled;
- at least one loading station comprising means for placing and retaining said container in front of said loading portion and in said assembly position;
- at least one unloading station comprising a vertical portion of rail ended by a lower portion, a conveyor extending horizontally under said lower portion, and means for effecting an unloading sequence comprising a downwards displacement of said carriage on said vertical portion while the container is retained by its own weight on the conveyor.

Apparatus for transporting loads comprising:
- at least one self-propelled carriage having a longitudinal axis and movable on rails along said axis, said carriage being provided with a first assembly profile oriented parallel to said axis and with first locking means;
- at least one removable container having a second assembly profile shaped so as to be slidingly assembled with said first assembly profile once placed in an assembly position by effecting a relative translational displacement of said carriage with respect to said container along said longitudinal axis on a loading portion of said rail, said removable container further having second locking means which cooperate with said first locking means so as to provide a rigid attachment between said carriage and said container once assembled;
- at least one loading and unloading station comprising a vertical portion of rail ended by a lower portion including said loading portion, a conveyor extending horizontally under said lower portion, means for effecting an unloading sequence comprising downwards displacement of said carriage on said vertical portion until the container comes to bear on said conveyor, an unlocking step of said locking means and an upwards displacement of said carriage on said vertical portion while the container is retained by gravity on the conveyor, and, means for effecting a loading sequence comprising a conveying step to bring said container on said conveyor in said assembly position, a displacement of the carriage down to said loading portion while the container is bearing on said conveyor and a locking step of said locking means.
