Definitions

  • the present invention relates to a piece of machinery for the movement of objects.
  • machinery which has trolleys associated in a removable manner with a supporting structure along a substantially rectilinear direction.
  • the machinery can be installed both in closed environments, e.g. inside warehouses and factories, but also in open environments such as maritime and railway depots.
  • One of the most common known type of machinery is an overhead crane comprising a load-bearing structure provided with a single guidance means for the movement of a device for the transport of objects along a first substantially rectilinear direction of movement.
  • the device for the transport of objects is associated in a movable manner with the guidance means and is therefore movable along a portion or the entire extension of the guidance means itself.
  • such machinery is also provided with movement means for moving the load-bearing structure along different directions of movement.
  • patent document no. 102016000002169 teaches the use of a piece of machinery for the movement of objects comprising a supporting network to which a plurality of devices for the transport of objects is coupled in a removable manner.
  • the supporting network comprises a plurality of guides which are adapted to guide the movement of such devices and which intersect transversely with each other to define the mesh of the network itself. This way, the devices for the transport of objects can be moved along different directions of movement without interfering with the displacement of the other devices.
  • this type of devices is provided with a first body and a second body arranged at the upper face and the lower face respectively, of the supporting network and coupled together by interposition of appropriate coupling means which cross the network itself.
  • the coupling means use one or more movable coupling elements which guarantee the mechanical coupling between the first body and the second body and at the same time do not interfere with the movement of the device for the transport of objects along the supporting network.
  • each of such devices needs to be electrically powered and to receive and transmit data, e.g., positioning/movement data on the supporting network, device status data and the like.
  • the component parts of the known type of machinery are generally connected by cable to a power supply/data transmission line, thus creating a complicated network of cables that becomes increasingly dense and intricate as more and more devices operate on the supporting network. Nevertheless, the cables can become tangled within the supporting network or tangle with each other during the movement of one or more devices for the transport of objects, greatly increasing the risk of malfunction and/or failure of the machinery of known type.
  • the main aim of the present invention is to devise a piece of machinery for the movement of objects that allows interconnecting the component parts to each other of the machinery itself.
  • An additional object of the present invention is to devise a piece of machinery for the movement of objects that allows interconnecting the first body to the second body of the devices for the transport of objects.
  • Another object of the present invention is to devise a piece of machinery for the movement of objects that allows simplifying the operations of movement of the objects and reducing the time required for the performance of these operations with respect to the machinery of known type.
  • Yet another object of the present invention is to devise a machinery for the movement of objects that allows overcoming the aforementioned drawbacks of the prior art within a simple, rational, easy, effective to use and low cost solution.
