Definitions

  • the invention relates to an office cutter having a chassis which can be placed on a table, said chassis comprising a fixed support plate for one or more sheets to be cut, a movable part mounted in translation relative to said plate, a knife whose one end is pivotally mounted on said movable part so as to struggle in a plane perpendicular to said plate by cooperating with a counter knife to cut the sheet placed on the plate and a translation mechanism for moving the part mobile, said knife and counter knife having curved ends for cutting a strip leaving a tab.
  • a cutter of the kind mentioned is the subject of European patent application No. 0 491 633, of the applicant, to which the reader requests will advantageously refer for the details of construction and operation of this cutter.
  • This known cutter includes an electric control for moving the movable part, but the knife is actuated manually using a handle disposed on the opposite side of the joint.
  • the effort to be provided is not negligible, in particular at the end of the cutting stroke and the aim of the present invention is to allow control by a motor, in particular electric, of the aforementioned cutter.
  • the guillotine according to the invention is characterized in that it comprises a rotary motor, in particular an electric motor and a crank system for connecting between the motor and the knife, arranged so that one of the neutral positions of the crank system substantially corresponds to the lowered cutting position of the knife.
  • the crank transmission allows the use of a low power motor, controlled by a simple push button.
  • the crank system is a crank associated with a connecting rod, a simple eccentric, a cam system or any other operating mechanism.
  • the raised position of the knife corresponds to the other dead center of the crank system. It is advantageous to use a motor with only one direction of rotation, the passage of the neutral points automatically ensuring the reversal of the direction of movement of the knife, but it is possible to provide for a reversal of the direction of rotation of the motor.
  • a limit switch stops the motor when the neutral point is raised and a new cycle is triggered by the push button with possibly locking and safety systems, preventing any false maneuver and a lowered knife stop.
  • the motor for example of the geared motor type, is carried by the movable part and on its axis is keyed a crank, connected by a connecting rod to the knife, preferably in the vicinity of the end opposite the articulation.
  • the cutter advantageously has a compression bar for the sheets to be cut, capable of occupying a raised position, for positioning the sheets on the plate and a lowered clamping position and, according to a development of the invention, the movement of the bar compression with respect to the plate is derived from that of the knife.
  • the compression bar is biased in the compression position by springs and it is moved in the raised position, against the springs, by a finger carried by the knife. This movement occurs at the end of the knife raising stroke, when the crank approaches the top dead center and is capable of providing the required lifting force. From the start of the knife lowering movement the compression bar moves under the action of the springs in the leaf clamping position.
  • a chassis 10 of generally parallelepipedal shape has on its upper face a plate 11 for supporting sheets, not shown. At one of the lateral edges of the chassis 10 is rigidly secured a slide 12 for supporting and guiding a movable part 13.
  • a knife 14 is articulated at 15 on the end of the movable part 13 for struggling in a plane perpendicular to the plate 11.
  • the movable part 13 carries a counter knife 16 and the frame 10 carries a bar 18 for compressing the sheets to be cut, which are positioned on the plate 11 at predetermined locations.
  • On the end of the blade of the knife 14 is elastically fixed a transverse blade 17, which cooperates with a curved part of the end of the counter knife 16.
  • the latter cuts a strip leaving a tab of greater or lesser length.
  • the position of the sheet, relative to the knife 14 is adjustable by displacement of the movable part 13, to cut tabs of different lengths and this displacement is controlled by a system of screws and nuts, driven by an electric motor (not shown) .
  • the relative positioning of the sheets can be achieved in a different way.
  • the mobile part 13 carries an electric motor 19, on the axis of which is keyed a crank 20, connected by a connecting rod 21 to the knife 14.
  • the connecting rod 21 is articulated to the knife 14 in the vicinity of its end opposite to the articulation 15.
  • the rotation of the motor 19 causes the connecting rod 21 and the crank 20 to tilt the knife 14 between the raised and lowered positions and the assembly is arranged so that in the lowered position of the knife 14, the connecting rod 21, crank 20 system is at bottom dead center and in the raised position at top dead center.
  • the motor 19 can be in one direction of rotation, the stop in the raised and / or lowered position of the knife being controlled by limit switch contacts (not shown).
  • the starting of the motor 19 is controlled by a push button or in any other way.
  • the compression bar 18 is mounted in translation perpendicular to the plate 11, being guided by two rods 22, fixed on the top of the plate 11.
  • the bar 18 is extended upwards by a plate 25, the upper edge 26 of which is curved and crossed by the rods 22, so as to effectively guide the sliding of the bar 18.
  • the amplitude of the up and down movement of the bar 18 is low and this movement is controlled by a finger 27, carried by the knife 14, which comes, at the end of the stroke for raising the knife 14, abut against the edge 26 and drive the bar 18 upwards against the springs 23.
  • the electric motor 19 of the gearmotor type can be of low power, since the crank system 20 generates, in the vicinity of the bottom dead center, the large force necessary for the movement of the knife 14 at the end of the lowering stroke and, in the vicinity of the top dead center, the large force required to raise the compression bar 18.
  • the cutter is automated by simple means, without any significant modification to the basic device.
