Definitions

  • the present invention relates to an apparatus for cutting sheet material, for instance for cutting fabrics for clothing and hide goods, footwear items, automotive and furnishing articles or hides, non-woven fabrics, synthetic materials and the like, and the following description is made with reference to this application field with the only purpose of simplifying the exposition thereof.
  • the material to be cut may be for instance hide, a fabric, a non-woven fabric, a synthetic material and the like.
  • These apparatuses are equipped with a conveyor belt capable of moving the sheet to be cut through a cutting area, above which one or more movable cutting heads work.
  • Said movable cutting heads may generally be translated both along a sheet-forward longitudinal axis X and along a transversal axis Y; furthermore, they may be lowered and raised along a vertical axis Z.
  • the cutting heads' displacement system may take up different conformations: for instance, it may take advantage of a crosspiece, which is movable along the forward axis, or it may be provided with an assembly having drives along the three axes which is entirely suspended from a fixed crosspiece.
  • a further drawback is the large dimensions and considerable weight of the displacement system, especially when the design choice of the fixed crosspiece is preferred - for instance for making a cutting apparatus with closed cutting tunnel or chamber.
  • Another drawback relates to the extension along the longitudinal axis of the working area of the cutting heads. If the cutting head is enclosed in a cutting chamber or in a closed tunnel, considering the dimensions of the head itself, indeed it is not possible to reach at least one of the ends of the chamber with the cutting tool.
  • the technical problem of the present invention is to provide an apparatus for cutting sheets which solves at least some of the prior art drawbacks, and which in particular allows displacing the cutting heads in a large working area through a robust mechanical system of limited weight and dimensions.
  • an apparatus for cutting at least one sheet material comprising:
  • the solution idea underlying the present invention thus derives from the adoption of a load-bearing crosspiece which supports the cutting heads and the displacement system thereof, wherein the elements directly supported by the crosspiece - i.e. the upper carriages - although sharing the same trajectory, slide on distinct rails or guides.
  • the elements directly supported by the crosspiece - i.e. the upper carriages - although sharing the same trajectory, slide on distinct rails or guides.
  • the approaching of the carriages with partial interpenetration allows the cutting heads, thereby supported, to be substantially side by side to each other, without weakening the support structure, i.e. without giving up the necessary transversal extension of the attachment sliders of the upper carriages.
  • said first and said second upper carriages comprise at least one first slider constrained to the at least one first guide and at least one second slider constrained to the at least one second guide.
  • the sliders may be constrained to the guides through dovetail counter-shaped profiles or other analogous profiles; preferably, but not necessarily, the guides are rail-shaped, i.e. they provide the male portion of the profile, whereas the sliders provide the female portion of the profile.
  • At least one of said first and second sliders may develop at least partially in a protruding manner, along the transversal direction, with respect to a main body of the respective upper carriage; said first and second upper carriages being configured so that, in a position in which they are relatively side by side to each other, the protruding development of the slider overlaps transversally - i.e.: it slides side by side without interfering on the longitudinal plane - the main body of the other upper carriage.
  • the sliders are mounted at the two opposite ends of transversal supports and completely or mostly protrude with respect to the below main body of the carriage.
  • the first guides are at least two; and the second guides are at least two.
  • the choice of at least two guides gives the drive structural solidity and allows a correct download of the suspended masses without generating torques that could cause a warping of the guides and/or of the sliders.
  • each upper carriage will have at least one slider constrained to an internal guide - i.e. arranged between other two guides - and at least one slider constrained to an outer guide.
  • the internal slider will be able to insert into a volume suitable left free in the structure of the other carriage; instead, the outer slider will preferably arrange at the side of the other carriage.
  • said first guides comprise a first horizontal guide and a first vertical guide
  • said second guides comprise a second horizontal guide and a second vertical guide; the first and second horizontal guides being associated with a lower face of the crosspiece; the first and second vertical guides being associated with opposite side faces of the crosspiece.
  • each slider may advantageously be L-shaped, with a horizontal base on which the at least one horizontal slider is mounted and a short end vertical wall, on which the at least one vertical slider is mounted.
  • the displacement of the first and of the second upper carriages with respect to the crosspiece is preferably actuated by screw/nut screw systems comprising a transversal screw which is fixed with respect to the crosspiece and a first and a second rotary nut, both engaged to said transversal screw, placed on the first and second upper carriages, respectively.
  • the cutting heads' displacement system may comprise, in addition to the above upper carriages: a first arm and a first lower carriage which define, together with said first upper carriage, a kinematic structure for the displacement of the first cutting head; a second arm and a second lower carriage which define, together with said second upper carriage, a kinematic structure for the displacement of the second cutting head.
  • Said first and second arms are preferably mounted below the first and second upper carriages, respectively, and are translatable with respect thereto along a longitudinal direction, whereas said first and second lower carriages are mounted below the first and second arms, respectively, and are translatable with respect thereto along the same longitudinal direction.
  • the displacement along the longitudinal axis Y of the cutting head is defined by the sum of two displacements, the one of the arm with respect to the upper carriage and the one of the lower carriage with respect to the arm.
  • Said expedient allows an overall travel of the cutting head along the longitudinal axis Y which is significantly greater than the longitudinal length of the arm.
  • Said first and second arms preferably have a prevalent extension along the longitudinal direction and comprise upper longitudinal guides and lower longitudinal guides engaged with lower sliders of the upper first and second carriages and with upper sliders of the lower first and second carriages, respectively.
  • the transversal movements of the first and second arms with respect to the upper first and second carriages and of the lower first and second carriages with respect to the first and second arms are preferably actuated by means of screw/nut screw systems.
  • Cable bundles are also preferably provided, which are suitably inserted in drag chains and which connect the upper carriage, the arm and the lower carriage.
  • the first and second lower carriages define support shelves for the first and second cutting heads respectively; a drive is provided along the vertical axis Z which allows the head to be lowered in the working position and to be raised in the rest position.
  • At least one of said lower carriages - preferably both - may be alternatively positioned in a first configuration, in which the cutting head faces towards a sheet-feeding inlet, and in a second configuration, in which the cutting head faces towards the opposite direction.
  • the re-positioning of the lower carriage may be carried out manually by the operator, for instance by extracting the element in the direction of the lower longitudinal guides and re-inserting it in the inverted position.
  • the crosspiece is preferably a fixed crosspiece with respect to the frame of the cutting apparatus.
  • the apparatus comprises a cutting chamber - i.e. a closed and delimited volume at least laterally and above - within which the cutting area is defined.
  • the cutting apparatus according to the invention may further optionally comprise an artificial vision system intended for the acquisition of an image of the sheet in order to plan the cutting operations thereon; said artificial vision system may advantageously comprise at least one image acquisition device housed in an area inside said crosspiece and facing the below cutting area.
  • the load-bearing crosspiece in addition to performing the support function of the entire cutting assembly, becomes an ideal support for the image acquisition devices inside the cutting chamber.
  • the crosspiece may conveniently be made of a metal section, itself hollow, in which suitable holes are made to arrange the image acquisition devices.
  • the arrangement of the image acquisition devices inside the crosspiece takes advantage of the fact that the below cutting assembly, although moving below the crosspiece in the working configuration itself and inevitably hindering a sight line between the image acquisition device and a cutting area, can be brought back to a rest configuration - specifically: with the carriages positioned in respective and opposite lateral end-stroke positions - in which said sight line is not obstructed.
  • the image acquisition devices are in a number greater than two, for example five, aligned along the transversal direction.
  • the artificial vision system may further comprise an upstream image acquisition device, still placed within said cutting chamber, for instance associated with the upper port of a front portion of the cutting chamber.
  • the artificial vision system may still comprise one or more image acquisition devices upstream of the cutting chamber, in combination or alternatively to those arranged in the front portion of the chamber.
  • the upstream devices are preferably a plurality, in a number and configuration equal to the downstream image acquisition devices.
  • the various image acquisition devices are advantageously arranged as a grid or matrix and may thus cover a rectangular surface which ranges and substantially corresponds to the perimeter dimension of the cutting chamber.
  • the upstream devices may cooperate with the downstream devices to realize a detailed and complete image of the below sheet to be cut; anyway, an advantageous independent use thereof is not excluded, for instance to perform an image acquisition during the cutting operations which interfere with the vision field of the downstream devices.
  • the image acquisition devices may be they downstream or upstream, may be a video camera or camera of the digital type, for instance of the CCD type. Moreover, they may incorporate a processor adapted to process a file of image data in a format processable by a control unit of the apparatus.
  • an apparatus according to the present invention is globally and schematically indicated with the reference number 1.
  • a transversal direction X a longitudinal direction Y - parallel to the forward direction of the sheet 2 inside the apparatus 1; finally, a vertical direction Z.
  • the apparatus 1 is adapted to process, and in particular to automatically cut, folding or flexible sheets 2 of materials, for instance fabrics for clothing items, leather goods, footwear items, automotive and furnishing articles or non-woven fabrics, hides, synthetic materials and the like.
  • sheet indicates any element of any shape and material, having a substantially two-dimensional size and a certain thickness (generally reduced), which must be cut through the apparatus 1.
