Definitions

  • the present invention relates to an elevating machine for lifting reels in sheets or the like.
  • reels of film in sheets consist of a film, made of material that differs according to the intended use, which is wound around a hollow sleeve of mainly cylindrical shape.
  • the reels can reach dimensions that are very different the one from the other.
  • the overall dimensions and the weight of the reels is such as to make very inconvenient or completely rule out the possibility of handling them manually; in these cases the use has to be made of special types of fork-lift trucks used to lift, overturn and transport the reels.
  • Such trucks usually consist of a motorised base frame having a reel grip unit and a grip unit lifting and overturning system.
  • the grip unit usually consists of an elongated cylindrical liner that can be fitted axially inside the sleeve and which has side walls extensible in a radial direction so as to grip the inner surface of the sleeve.
  • the lifting and overturning system on the other hand consists of a vertical structure along which slides a slide that supports a horizontal support arm for supporting the grip unit.
  • rotating means are placed that permit turning the grip unit between a vertical and a horizontal position.
  • the reels to be handled are usually placed resting on one side and the axis of the sleeve is arranged vertically; during the reel gripping phase, therefore, the grip unit is positioned vertically above the reel, is aligned coaxially with the sleeve and is then fitted in the sleeve by the lowering of the slide along the vertical structure of the fork-lift truck.
  • the grip unit can be easily lifted to move the reel off the ground and, if necessary, return it to horizontal position, so as to allow 90° overturning of the reel.
  • the reels can be positioned at a limited height, so that the operator driving the fork-lift truck can see them without leaving his/her place of work; such solution, however, represents a strong limitation to the exploitation of the available storage space, with consequent costs due to failure to make use of such space.
  • the main aim of the present invention is to provide an elevating machine for lifting reels or the like that can be used in a practical and easy way even by just one operator and which, at the same time, allows rationally exploiting the space available in the store, permitting the positioning of the reels in stacks or on shelves.
  • a further object of the present invention is that it is particularly attractive from an economic viewpoint, and permits a big cut in labour management costs and/or storage costs.
  • Another object of the present invention is to provide an elevating machine for lifting reels or the like that allows overcoming the above-mentioned drawbacks of prior art within the ambit of a simple, rational and low-cost solution.
  • this elevating machine for lifting reels or the like comprising at least a base frame moving on the ground having lifting means for lifting a grip unit for gripping at least one reel, said grip unit comprising a liner that can be fitted in the sleeve of said reel and attachment means for attaching to the inner surface of said sleeve that are associated with said liner, characterized in that said grip unit comprises detection means for detecting the position of said sleeve.
  • the present grip unit for lifting reels or the like on elevating machines comprising a liner that can be fitted on an elevating machine and that can be inserted in the sleeve of a reel to be gripped, and attachment means for attaching to the inner surface of said sleeve which are associated with said liner, characterized in that it comprises detection means for detecting the position of said sleeve.
  • the reference numeral 1 globally designates an elevating machine for lifting reels or the like.
  • the machine 1 comprises a base frame 2 which has wheels for movement on the ground, not shown in the illustrations, and a driving and control post 3 for an operator.
  • the base frame 2 also has lifting means 4 for lifting a grip unit 5 suitable for gripping and releasing a reel B of film in sheets.
  • the lifting means 4 are of the type of a structure of vertical uprights 6 along which slides a slide 7 that supports a horizontal support arm 8 supporting the grip unit 5; between the horizontal arm 8 and the grip unit 5 are placed rotation means 9 that allow turning the grip unit 5 between a vertical and a horizontal position.
  • the grip unit 5 comprises a liner 10 which can be fitted axially inside the sleeve M of the reel B; this has an elongated cylindrical conformation and a connection end 11 connecting it to the lifting means 4 and a free end 12 opposite the connection end 11.
  • the attachment means 13 comprise a plurality of contact elements 14, of the curvilinear plate type arranged around the liner 10 and moving crossways with respect to the longitudinal axis of the liner 10 between a retracted configuration, in which the plates 14 are arranged close to the liner 10, and an extended configuration, in which the plates 14 are arranged away from the liner 10.
  • a piston 15 is arranged sliding longitudinally and suitable for operating the plates 14 transversally.
  • the outer side surface of the piston in fact, has a series of surfaces 16 sloped with respect to the axial direction, on which slide corresponding wedges 17 that support the plates 14.
  • the grip unit 5 comprises detection means 18 for detecting the position of the sleeve M of the reel B.
  • Such detection means are of the optical type and involve a camera 19 fitted inside the liner 10 close to the free end 12.
  • the liner 10 has a support flange 20 for supporting the camera 19, which has an open centre portion 21 onto which faces the lens of the camera 19.
  • the piston 15 has an end section 22 having a housing seat 23 for the camera 19; the presence of the housing seat 23, in point of fact, permits an excellent integration of the camera 19 inside the liner 10, exploiting to the utmost the available room and preventing awkward limitations of the stroke of the piston 15.
  • the detection means 18 comprise reproduction means for reproducing the images taken by the camera which, for example, consist of a monitor, not shown in the illustrations, which is fitted to the base frame 2 at the driving and control post 3.
  • the operator controlling the movement of the elevating machine is able to see the entrance of the sleeve to be gripped even when the reel is arranged in raised position, on shelving or on a stack of other reels.
  • grip unit according to the invention are such as to allow not only their fitting on newly-made elevating machines, but also installation on elevating machines already made and in use, thus also permitting their marketing as highly practical and affordable separate accessories.
