Definitions

  • the present invention relates to a rotary blank cutting machine, intended in particular to be used in a unit for shaping corrugated boxes.
  • a rotary cutter of cardboard blanks essentially comprises two superimposed cylinders, with horizontal and parallel axes.
  • the first cylinder called “tool cylinder” or “cutting cylinder”
  • the other cylinder called a “counterpart cylinder” or “anvil cylinder”
  • a flexible coating such as polyurethane.
  • the cutting tool penetrates into the flexible coating of the counterpart, and by cutting effect cuts the sheet of cardboard driven continuously between the two cylinders, the latter being themselves driven in rotation by the general movement of the machine.
  • the connection between the two cylinders is fixed and ensured by a pinion transmission device.
  • the cutting precision is only satisfactory if the circumferential speeds of the two cylinders are in an appropriate ratio, taking into account the wear of the coating of 1s. counterpart and the penetration depth of the cutting tools in this coating.
  • the same remark is valid in the case where the cut shape carries non-cutting threads intended for the crushing backing of the cardboard plate: the positioning of the pushing back is satisfactory only if the circumferential speeds of the two cylinders are in a given ratio taking into account the wear of the coating and the penetration depth of the upsetting tool therein.
  • the present invention relates to a rotary cutting installation equipped with means making it possible to automatically obtain the circumferential speed ratio between the two cylinders which gives optimum cutting or upsetting precision.
  • Such an installation is characterized in that it is equipped with a device for driving the counterpart cylinder by means of a friction device driven from the cutting cylinder.
  • the rotary cutting installation of the invention comprises a supporting frame 1, an upper cutting cylinder 2, provided with a tool holder 3 and tools (4 , 5) and a cylinder against the lower part 6 coated, in a conventional manner, with a flexible polyurethane coating.
  • the cutting machine comprises a slide support 7, bolted to the frame 1 and parallel to the axis of the cylinders (2, 6) on which a rectification head 8 supporting can move. a cutting tool 9 intended for grinding by scraping of the cylinder 6.
  • the head 8 can move along the slide 7 parallel to the axis of the cylinder 6 using the conventional device with nut 10, endless 11, and motor 12 for driving the screw 11 in rotation, shown in FIGS. 1 and 2.
  • the rotation of cylinder 6 during the grinding operation with tool 9 can be obtained simply by driving the machine by the general movement of the total shaping installation of which it is a part.
  • the machine is assumed to be separated from the rest of the installation during the rectification phase, so that the rotational drive of the assembly during the rectification phase is carried out from an electric motor.
  • auxiliary 42 driving in rotation, by means of a toothed pinion 13, the toothed pinion 14 intended for driving the cylinder 2 and consequently, as will be explained below, of the cylinder 6.
  • the pinion 14 is precisely that which, when the machine is in place in the overall shaping installation, is driven by the general movement of said installation.
  • the toothed pinion 14 rotates the cylinder 2 using a shaft 15 and bearings (16,17).
  • the other end of the shaft 15 carries a wheel 18 of diameter equal to that of the cutting tools (4,5).
  • the lower cylinder 6 is extended, as can be seen in the drawings, by a wheel 19 placed under the wheel 18, and therefore resting thereon, of diameter equal to t / that of the cylinder 6 and coated with the same flexible polyurethane coating as the latter or at least with a soft coating of the same type, that is to say soft enough to be able to be rectified by the tool 9 to the same degree as this rectifies the cylinder 6.
  • the slide 7 is of sufficient length so that the tool 9, in its transverse movement, comes to rectify the wheel 19 exactly to the same diameter as the cylinder 6.
  • the toothed pinion 14 meshes with a pinion 20 of the same diameter which rotates, by means of a bearing 21, around an eccentric pinion 31 whose angular position is adjustable using a gear wheel device 32, chain 33, pinion shaft 34 and crank 35, the elements 31 to 35 being found symmetrically at the other end of the cylinder 6.
  • the eccentric shaft 22 of the cylinder 6 rotates in the two parts 31 by means of bearings 23. On the left side with respect to the figures, it is rigidly connected to the wheel 19 and on the right side it is connected via 'a freewheel 24 to a pinion 25 driven by meshing by the internal toothing of the pinion 20, as shown in the drawings.
  • the circumferential speed of the latter remains, thanks to the device of the invention, strictly equal to that of the cutting cylinder 2.
  • the pinions 14, 20 ′ and 25 gave angular speeds and circumferential speeds rigorously equal for the two cylinders.
  • the cylinder 6 has a smaller diameter, so that the latter is then, driven, at a higher angular speed but at unchanged circumferential speed, by friction of the wheel 18 on the wheel 19, rectified at same diameter as the cylinder 6.
  • the pinion 25 no longer drives anything because the free wheel 24 triggers, its angular speed being greater than that of said pinion 25.
  • the pinions 20 and 25 operate only in the event of incident creating a resistant overtorque, and therefore a slowdown of the whole.
  • FIGS. 5 and 6 schematically represent two examples of possible variants for driving the lower cylinder by friction from the upper cylinder, these two variants being in particular intended to be used when it is not possible, either for lack of space, or because one operates on an old installation, to place wheels such as the wheels 18 and 19 at the end of the shafts.
  • the cutting cylinder 2 is provided at its two ends with rings (50, 51) which directly drive the counterpart cylinder 6 by friction.
  • the rings 50 and 51 are then removed, so that the cylinder 6 is driven by the freewheel system 24 and pinions (20, 25) described above, which is of less importance because very precise cutting is not necessary for large formats.
  • FIG. 6 shows another possible variant of driving the cylinder 6 by friction from the cylinder 2.
  • a belt 52 is used which is wound in the opposite direction as shown around the cylinders 2 and 6, then around a idler 53.
  • the embodiment according to FIG. 1 consists, in short, in creating an "image" (18, 19), on a reduced scale in the longitudinal direction, of the cutting cylinders 2 and of counterpart 6.
  • the shaft connecting the wheel 19 to the cylinder 6 is a mechanical shaft.
  • the auxiliary drive pinion 20 and its associated freewheel 24 can very well be eliminated.
  • the cylinder 18 will be provided with tools reproducing, on a reduced scale in the longitudinal direction, the tools equipping the cutting cylinder 2.
  • the cylinder 19, then being mounted idly on its axis, will then take, because of its very low inertia, of itself the optimal speed resulting from the wear of its coating and the penetration depth of the tools. This speed, which then corresponds to the optimal speed for cutting or upsetting, is then automatically transmitted to the counterpart cylinder 6 via the electric or hydraulic shaft.
  • FIG. 7 is a schematic representation in longitudinal section of an installation of this type. As indicated above, this installation differs essentially from that of FIG. 1 by the fact that the wheel 19 drives the cylinder 6 via an electric shaft, and not not mechanical.
  • the wheel 19 is then mounted idle, using the bearings 40, on the shaft 22 of the cylinder 6. It drives a tachometric dynamo 41 which provides on its output 42 an electrical signal representative of its speed of rotation.
  • the speed signal 42 is applied to a comparator 43, provided with an electric power input 44, and supplying on its power output 45 an electric voltage to a variable speed electric motor driving the shaft 22 and therefore the cylinder 6 .
  • the power motor 46 is coupled to a tachometer generator 47 which supplies a regulation signal by its output 48 on the second comparison input of the comparator 43.
  • the rectification device which equips the installation of FIG. 1 has been eliminated.
  • the wheel 18 has been equipped with identical tools 4 ′ to the tools 4 fitted to the cylinder 2, but reduced in the longitudinal direction in the ratio of the longitudinal dimensions of the cylinders 18 and 2.
  • the reduced image of the cylinders 2 and 6 is reproduced exactly.
  • the cylinder 19 is coated with the same coating as the cylinder 6. This coating wearing out in the same way, and the inertia of the wheel 19 being negligible, the wheel 19 then assumes by itself the optimum circumferential speed. for cooperation (18, 19), and this optimum speed is transmitted to cylinder 6 by the electric shaft (41 to 48).
