Definitions

  • the present invention relates to a device suitable for allowing the selective insertion of different types of cardboard at an infeed station of a machine.
  • Machines suitable for performing a plurality of processes on corrugated cardboard are in fact currently known.
  • This solution thus provided a station for the feeding of cardboard which comprises a supporting frame; the shafts of three rolls, each constituted by corrugated cardboard with different width and/or length, being freely pivoted to the side members of said supporting frame.
  • the aim of the present invention is therefore to eliminate the disadvantages described above in known types by providing a device which allows to feed, at one or more successive stations, one of at least two different types of cardboard.
  • Another important object is to provide a device wherein the selection of the required type of cardboard to be fed can occur automatically, without the manual intervention of an operator.
  • Another important object is to provide a device which allows to rapidly and easily vary the choice of the required type of cardboard to be used.
  • Another important object is to provide a device which associates with the preceding characteristics that of being structurally simple and of being applicable to known machines as well.
  • Not least object is to provide a device which associates with the preceding characteristics that of being reliable and safe in use and of having modest costs.
  • the reference numeral 1 indicates the device for the selective insertion of two different types of cardboard, such as for example a first cardboard 2, unrolled from a roll 3, and a second cardboard 4, which is folded several times in an accordion fashion and is known in the field as "fanfold” or "endless cardboard".
  • the roll 3 is rotatably arranged at adapted supports 5, and the device 1 is arranged below it, whereas the pack which constitutes the second cardboard 4 is arranged to the side.
  • first surface 6 which is a part of a machine adjacent to the device, such as for example a cardboard processing machine.
  • the device 1 comprises at least one actuator which is constituted by a piston 7 the body 8 whereof is articulated, at one end, to an adapted support and the stem 9 whereof is also articulated at the median region of a first bar 10 of a motor unit 11.
  • Said motor unit is constituted by a first pair of pulleys 12a and 12b which are connected by the first bar 10; one of said pulleys is motorized by means of a single motor 13.
  • the mechanical connection between the first pair of pulleys is naturally obtained by means of an adapted first belt or first chain 14 which interacts with an adapted presser 15 which is elastically associated with the first bar 10.
  • the piston 7 and the motor unit 11 are arranged below the first surface 6, with the pulley 12a freely pivoted at adapted supports.
  • Said means is constituted by a second pair of pulleys 16a and 16b which are rotatably supported at the ends of a second bar 17; said pulleys are interconnected by means of a second belt or second chain 18.
  • one pulley of said second pair of pulleys is freely pivoted at an adapted support in a region which lies above said motor unit 11, which thus provides motion, since the first belt or first chain 14 interacts with the second belt or second chain 18 also by virtue of the presence of the presser 15.
  • a first roller 19 is instead associated at the pulley 16b and interacts in two limit positions respectively with a second roller 20 and with a third roller 21, both of which are freely rotatably pivoted at adapted supports.
  • the first roller 19 does not interact directly with the surfaces of the second and third rollers, since these last interact respectively with the second cardboard 4 and with the first cardboard 2, which are drawn from the accordion pack and from the roll 3.
  • the first cardboard 2 is arranged adjacent to the third roller 21 by virtue of the presence of a pair of guides 22a and 22b which are suitable for guiding said cardboard at the adjacent first surface 6.
  • the second cardboard 4 instead rests at the lateral surface of the second roller 20 and then on an adapted second surface 23 which is adjacent to the first surface 6.
  • the interaction of the first roller 19 with the second cardboard 4 occurs in the position illustrated in figure 1, and thus with the arrangement of the motor unit 11 in horizontal position, the transmission of motion to the first roller 19 imposing a movement to the second cardboard 4 either toward the first surface 6 or in the opposite direction, for example to free the first surface 6 prior to the advancement of the first cardboard 2.
  • the presence of the presser 15, which is elastically supported by the first bar 10, allows to maintain optimum transmission of motion from the first belt or first chain 14 to the second belt or second chain 18.
  • the rotation thus imparted to the motor unit 11 causes a rotation of the second pair of pulleys 16a and 16b until the first roller 19 interacts with the first cardboard which, being pressed between the first roller and the third roller, is pushed through the pair of guides 22a and 22b at the first surface 6.
  • the motion at the motor 13 can be alternated so as to allow the rewinding of the first cardboard at the roll 3 in order to free the first surface 6 for the advancement of the second cardboard 4.
  • the invention has achieved the intended aim and objects, a device having been provided which allows to insert, at successive stations, two different types of cardboard, the type of cardboard being processed being automatically preselectable without requiring any manual intervention on the part of an operator.
  • figure 2 illustrates a second embodiment, wherein the motor unit 111, which comprises a single motor 113, is again constituted by a first pair of pulleys 112a and 112b, one of which is itself a part of a unit 126 for transmitting motion at a means for enabling the movement of the first cardboard 102 or of the second cardboard 104.
  • the motor unit 111 which comprises a single motor 113
  • the motor unit 111 is again constituted by a first pair of pulleys 112a and 112b, one of which is itself a part of a unit 126 for transmitting motion at a means for enabling the movement of the first cardboard 102 or of the second cardboard 104.
  • Said transmission unit 126 comprises a first bar 110 which is pivoted, at its ends, to the pulley 112a and to one pulley of the second pair of pulleys 116a and 116b which constitutes said means for the selective enabling of the cardboard, said second pair of pulleys being interconnected by means of a second bar 117.
  • Said first and second bars are thus mutually pivoted at one end, the second bar 117 being arranged along a plane which is perpendicular to the second surface 123.
  • a first roller 119 is furthermore connected to the pulley 116b and has a pivot 127 which can slide at an adapted inclined plane 128 which forms an acute angle with the second cardboard 104 in the opposite direction with respect to said first surface 106.
  • the end of a stem 109 of a piston 107 is furthermore pivoted at the first bar 110; said piston is also arranged perpendicular with respect to the second surface 123.
  • the piston 107 thus allows to impart to the first and second bars a movement which causes the first roller 119 to interact with the first cardboard 102 at the third roller 121 and, upon a lowering of the first bar 110, the first roller 119 to interact with the second cardboard 104 at the second roller 120.
  • Figure 3 illustrates another embodiment, wherein the piston 207 again has a body 208 which is pivoted, at one end, to a fixed element the stem 209 whereof is associated at a first bar 210; a first pair of pulleys 112a and 112b is pivoted to said first bar 210, and the motion thereof is provided thereto by an adapted motorized roller or pinion 229.
  • the actuation of the piston 207 entails the rotation of the first bar 210 for example with respect to the pivoting axis of the pulley 112a, said rotation causing the pulley 112b to interact with a third pulley 230 which is suitable for providing motion to an adapted underlying traction roller 231 which interacts with a cardboard sheet obtained for example from a roll, from a sheet, a fanfold pack or from cardboard sheets pasted one after the other.
  • a second free roller 220 is provided on the side opposite to the traction roller 231 and is suitable for allowing the traction of the cardboard on the part of said traction roller.
  • Said traction roller 231 and said second roller 220 can be pivoted at an adapted lifting or transfer device 232 and thus be transferred sequentially at the same vertical or horizontal axis, so as to be able to provide motion to the roller pair of said pairs of traction rollers 231 and second rollers 230 which bear the type of cardboard.
