Definitions

  • the present invention relates to the technical field of cutting one by one semi-rigid sheets, in particular from cardboard, and more particularly, but not exclusively, in corrugated cardboard. She has main purpose of a cutting installation equipped with input a leaf launching device which has been perfected in sort of ensuring a new wedging function in position of sheets relative to the cutting tool.
  • a cutting installation is always integrated in practice in a sheet processing line that includes at least as the first upstream machine, a device for introducing leaves, commonly called feeder, and having in a way general function of automatically inserting the sheets one after the other at the line entrance at a given rate (time interval between two successive sheets) and in their giving a given linear speed.
  • the processing line only has a functionality of cutting the sheets
  • the machine downstream of the feeder is the installation cutting.
  • the line of processing also has the function of printing on the sheets, it includes between the feeder and the cutting installation a or several successive printing groups.
  • Cutting a semi-rigid sheet, especially from cardboard corrugated, is carried out on conventional cutting installations using a cutting tool and a support surface.
  • the cutting tool includes blades or support nets substantially perpendicular to the support surface when the sheet is compressed between this surface support and the cutting tool, so that the threads pass through the sheets and make the corresponding cut.
  • the cutting tool is mounted on a tool tray, also commonly known as marble, while the bearing surface is formed by the surface of a cylinder, called cutting cylinder.
  • the tool tray is designed to be in operation animated by a reciprocating movement of va and comes, which allows to move each sheet one after the other under the cutting cylinder from a sheet feeding position to be cut to a position for discharging the cut sheet.
  • Such a cutting installation is also equipped upstream of the tool tray and support surface, supply means allowing each sheet to be inserted on the tool tray when displacement thereof relative to the cutting cylinder.
  • these means supply systems include two successive systems for transporting leaves.
  • the first known as the transfer case, receives the sheet of a upstream machine (feeder or printing unit), and transfer to a substantially constant speed, equal to the exit speed of the sheet of the upstream machine.
  • the second known as the launch device, implements a launching belt which receives the sheet of transfer case and introduced it between the tool tray and the cutting cylinder.
  • the kinematics of the of the launching device belt is usually controlled so as to have a speed profile which is as follows.
  • the linear speed of the launching belt is constant and equal to the speed of the upstream transfer system.
  • the belt substantially accelerates to launch achieve the desired launch speed for the sheet (speed linear of the marble in the cutting phase).
  • the speed of the launching belt is kept constant (phase during which the sheet is introduced between the cylinder of cutout and the tool tray).
  • the launching belt decelerates substantially linearly until the transfer system speed is reached again upstream.
  • the speed of the drive belt launch is kept constant until the operating cycle next. It is important to emphasize that this speed profile, for a given cutting installation is always the same, whatever either the setting in position of the cutout relative to the sheet that we want to get.

In the case of electronic feeders, it is possible to remove this complex mechanics, however this type feeder due to its high cost price, is reserved for lines high range treatment.
  • the present invention provides a new solution to problem of timing in position of the sheets relative to the tool cutting, which is simple to implement and less expensive than currently known solutions, and which simplifies the feeders design.
  • the invention is based essentially on a modification brought to the leaf launching device at the entrance of a cutting installation, allowing this device to be launch of a new wedging functionality in position of sheets in relation to the cutting cylinder and the tool tray.

  • the motor M1 is controlled so as to drive this cutting cylinder 1 at a known predetermined constant speed, fixing the operating cycle of the installation (after an initial phase of linear acceleration when starting the installation ).
  • the motor M1 is a brushless motor.
  • this motor M1 does not require stepping, we can use more generally any motor delivering sufficient torque and allowing to rotate the cutting cylinder 1 at a substantially constant angular speed. We could thus use for example a vector asynchronous motor.
  • the marble 2 for its movement alternative to the cutting cylinder 1 is mounted so usual on two parallel racks 4 and 5, which mesh respectively each with two identical pinions 6 (only one of two pinions 6 being visible in FIG. 3), the two pinions being driven by a M2 brushless motor, through a set of transmission pinion 7.8.

  • the invention is not limited to the use of a brushless motor for the motor (M2), but that we can generally use any motor can be controlled with sufficient precision in speed and position.
  • marble 2 could be driven by the same motor as that (M1) used to drive the cutting cylinder in rotation.
  • the launching device 3 is positioned immediately upstream of the cutting cylinder 1, above the rear path of the plate 2.

  • the A3 leaf pushing device is coupled to the axis of rotation of the lower roller A2, by a pinion A5 driving a mechanism A6 known rod type, allowing to transform the rotational movement continuous of pinion A5 in an alternating movement of given amplitude.
  • this transmission chain does not allow any adjustment of the position of the mobile elements (A1, A2, A3) of the mechanical feeder by relative to the angular position of the shaft of this motor (M1). So, unlike the usual implementation of a mechanical feeder in a cutting installation, no provision is made between the feeder and the shaft mechanical control of this feeder (in this case secondary output gearbox R1) no synchronism system based on differentials allowing a user to program a delay or an advance of feeder operation in relation to the operating cycle of the cutting unit E.
  • the feeder A under the control motor rotation M1 is designed to deliver leaves one after the other, communicating a speed to each sheet data set by the speed of rotation of the rollers A1 and A2, and above all with a positioning of each sheet at the output of the feeder relative to the angular position of the cutting cylinder which is adjusted once for all during the design of the cutting installation, and which is not modifiable by a user of the installation.
  • This relative positioning corresponds to an initial setting of a sheet with respect to the cylinder of cutting, and determines an initial position of the cutting in the sheet.
  • each sheet output at feeder A is taken up directly by pinching between the plate cylinder B1 and the backpressure cylinder B2 of the printing group.
  • the transfer device C is known per se and will therefore not be detailed. It essentially implements a box containing a plurality of CT conveyor belts, of small width, parallel and spaced, and mounted tensioned, above a perforated curved plate P, on two rollers, one of which 17 a is motor and the other 17 b is mounted free to rotate.

  • This transmission chain is calculated so that the linear speed (V1) of the CT belts is constant (the motor M1 being driven at constant speed) and substantially equal to the linear speed of the sheets leaving the printing unit (circumferential speed backpressure cylinders B2 and plate holder B1).
