Definitions

  • the present invention relates to a locking device structure, particularly usable in cardboard processing machines during said cardboard traction feeding.
  • Machines suitable for performing a plurality of processes on corrugated cardboard are already currently known.
  • this solution provides the presence of a station for the feeding of cardboard which essentially comprises a supporting frame; the shafts of three rolls, each constituted by corrugated cardboard with different width and/or length, are freely pivoted to the side members of said supporting frame.
  • This solution has thus allowed to solve the problem related to the selective feeding of cardboard starting from rolls according to different dimensions, such as width and length.
  • the insertion system is expensive from both a mechanical and electrical-electronic viewpoint.
  • US-A-4792074 discloses an arrangement for the stepwise feed of band material which includes a first, locally fixed and driven feed roller and a second feed roller rotatably supported by a rocker; the rocker is loaded by a spring; a lifting mechanism is provided, by which the second feed roller is movable at the point in time of the reversal of the direction of rotation toward the first feed roller for an advance of the band material and away form the same into a return position in which the band material is to be held fixed.
  • the locking of the band material is achieved by an actuator which actuates a series of levers connected to a pressure device which abuts against the band material that in turn abuts against a counter element.
  • DE-B-1144577 discloses a feeding device for cardboard sheet or the like, particularly for punch cutter apparatuses.
  • the device comprises two compressed air driven actuators (16, 18) provided with two pistons (15, 17); the piston (17) of the actuator (18) carries an abutment element suitable to stop the feeding of the cardboard sheet in a predetermined position, while the piston (15) of the actuator (16) actuates a first roller (11) that is opposed to a second roller (13) to engage the cardboard therebetween.
  • the aim of the present invention is to stop the advancement of the cardboard unrolled from an inserter or reel-holder or from a fanfold pack, or from individual or pasted sheets, after the operation of cutting said cardboard.
  • An object of the present invention is to provide a device which allows both to achieve optimum feeding of cardboard and to feed said cardboard at one or more successive stations in the optimum position, although the cardboard is subjected to various and distinct processing steps.
  • another important object is to provide a device which prevents the extraction or escape of the cardboard from the traction rollers of the inserter while said cardboard is subjected to one or more successive processing operations.
  • Another important object is to provide a device which allows to contain manufacturing costs especially as regards the use of motorization systems.
  • Still another important object is to provide a device which associates with the preceding characteristics that of being reliable and safe in use.
  • Not least object is to provide a device which is structurally simple, is easy to apply even to known machines, and at the same time has modest manufacturing costs.
  • the locking device structure comprises a fixed support, such as a pair of shoulders 2a and 2b, between which a first roller 3 is freely pivoted; said first roller is motorized by a single source, such as an adapted motor, not illustrated, which is suitable for providing motion to said first roller 3, a gearwheel 5 being keyed at its first shaft 4.
  • the structure is furthermore constituted by at least one actuator, constituted by a piston 6, the body 7 whereof is pivoted, at one end, at an arm 8 which protrudes from a base support 9 which can be rigidly associated at the shoulder 2a.
  • the piston 6 furthermore has a stem 10, the end portion 11 whereof is U-shaped; one of two polygonal plates 12a and 12b is freely pivoted, proximate to an edge, between the wings of said end portion.
  • Said plates which are respectively adjacent to the shoulders 2a and 2b, have a lower perimetric edge 13a and 13b which is arranged proximate to the plane of arrangement of the underlying cardboard sheet 14, which in turn rests at the surface of the underlying first roller 3.
  • Said plates 12a and 12b which preferably have a rhomboidal plan configuration, are in turn pivoted, by means of a pair of first pivots 15a and 15b, respectively to said shoulders 2a and 2b proximate to the corner which is opposite to the pivoting corner of said end portion 11 of the stem 10.
  • Both of said plates 12a and 12b have, at the corner for pivoting to said first pivots 15a and 15b, an end on which a plate or presser 16 is fixed transversely to the plates 12a and 12b; said presser has a lanceolate configuration and is directed opposite to the direction of removal of the cardboard sheet 14.
  • the axis of the first shaft 4 of the first roller 3 is interposed between the axes for the pivoting of the end portion 11 and of the stem 10 to the plates 12a and 12b and the axis of the first pivots 15a and 15b; a second shaft 17 of a second counter-roller 18 is pivoted to said plates 12a and 12b at said first roller 3.
  • At least one abutment surface 19 for said cardboard sheet is provided below the plane of arrangement of the cardboard sheet 14 at the presser or plate 16 which connects the plates 12a and 12b.
  • the presser or plate 16 connected to the plates 12a and 12b is arranged approximately parallel to the plane of arrangement of the cardboard sheet 14 and said plates do not interact with said sheet.
  • the piston 6 is actuated, preferably before the step of cutting said cardboard, so as to retract the stem 10, thus disengaging the second counter-roller 18 from the cardboard sheet 14 and simultaneously causing the presser 16 to interact with said cardboard sheet, which is pressed at the underlying abutment surface 19.
  • the invention has achieved the intended aim and objects, a structure having been provided which allows to obtain the optimum traction of a cardboard sheet, thus achieving optimum feeding at modest manufacturing costs, allowing at the same time to lock the traction of the sheet, preventing the extraction thereof, if it is necessary to process said cardboard in adjacent stations of a more complicated machine which also provides, for example, the cutting of the cardboard in one of its operating steps.
  • the invention is furthermore structurally very simple, as well as easy and rapid to install even in known machines, and at the same time has very modest manufacturing costs which allow to considerably contain the machine manufacturing costs.
