Definitions

  • the present invention relates to the cutting one by one of semi-rigid sheets, in particular of cardboard and particularly of corrugated cardboard. More specifically, it relates to an improved device, specially adapted to perform this cutting at optimized rates according to the format of the sheet to be cut, and the kinematics of the machine.
  • the cutting of a semi-rigid sheet, in particular from corrugated cardboard, is carried out on conventional cutters using a cutting tool and a support surface.
  • the cutting tool comprises blades or threads perpendicular to the bearing surface when the sheet is pressed between it and the cutting tool so that the threads pass through the sheet and make the corresponding cut.
  • the cutting tool is positioned flat on a tool-holder plate and the bearing surface is a flat surface.
  • the cutting is carried out by applying the bearing surface against the tool-holder plate on which the sheet to be cut has been positioned.
  • the pressure which must be brought into play in a cutting machine of this type is very high, being able to go up to several thousand kilonewton.
  • the cutting tool is mounted on the periphery of a cylinder and the bearing surface is itself a cylindrical surface.
  • the cutting is carried out by introducing the sheet between the two cylinders driven in rotation.
  • the pressure involved is lower because the cutting is done in a linear fashion along the line of tangency between the two cylinders.
  • shaping the cutting tool so that it is adapted to the exterior surface of a cylinder is very delicate.
  • problems can arise when the sheet to be cut has a large thickness because the cutting threads being mounted radially, there is a difference in peripheral distance between the upper part and the lower part of two adjacent threads.
  • the cutting tool is mounted on a tool-holder plate while the bearing surface is a cylindrical surface.
  • the tool holder plate must, in this case, be animated by an alternating back-and-forth movement making it possible to move each sheet one after the other under or on the support cylinder from a position of feeding the cut sheet to an evacuation position of the cut sheet.
  • the cutter since the sheet to be cut comes from a previous station, either a printer or a feeder, the cutter also includes feeding means making it possible to precisely introduce said sheet on the cutting tool during movement of that -this under the support cylinder.
  • these feeding means consist of two sheet transport systems.
  • the first known as the transfer box, receives the sheet from the upstream machine, which can be a feeder or a printer for example. It has a constant linear speed equal to that of these machines.
  • the second known as the launching box, receives the sheet from the transfer box and introduces it between the tool holder plate and the support cylinder. At the start, it therefore has a speed equal to that of the transfer case, then it accelerates the sheet in order to give it a speed equal to that of the support cylinder according to the same acceleration law as the tool-holder plate.
  • the first object of the invention is to provide a cutter according to the third type mentioned above which overcomes the drawbacks mentioned above, namely for which the stroke of the support plate can vary depending on the format of the sheet and which avoids any offset in the positioning of the sheet on the cutting tool.
  • the electronic control circuit (24) is programmed so that in the first part the amplitude of the reciprocating movement is a function of parameter l , in the second part the linear speed of the tool-holder plate (10) is constantly equal to the peripheral linear speed of the support cylinder (9) as long as the cutting tool (16) is in contact with said support cylinder (9), and thirdly the difference which is noted between the theoretical position and the actual position of the predetermined element of the sheet (21), detected by the tracking system (26) is corrected by a correlative variation in the drive of the motor (28) equipping the launching means (8).
  • the invention it is therefore possible to reduce the stroke of the tool-holder plate when the format of the sheet to be cut and therefore the length l of the cutting tool are less than the maximum dimension. L provided by the manufacturer. This correlatively increases the production rate of the cutter or, keeping the same rate, reduces the electrical power consumed.
  • the sheet which is either ahead or behind when it leaves the previous station sees its feeding speed reduced or accelerated so that it is introduced on the cutting tool very precisely under the conditions required. We therefore obtain an automatic correction of the positive or negative difference from the previous item.
  • the predetermined element is the front or rear edge of the sheet; in this case the tracking system preferably consists of a position sensor.
  • the predetermined element is a given printed area of the sheet; in this case the tracking system preferably consists of a camera, capable of detecting said printed area.
  • the cutting tool includes a system allowing the sheet to be held in place during cutting and then ejecting it when the tool-holding plate is in the second position.
  • This system works using flexible tubing which functions as suction cups during the forward movement and which functions as ejection tubing by sending compressed air when the tool-holder plate is in the second position.
  • the cut sheet, which is ejected, is taken up by a discharge device.
  • the electronic control circuit is programmed so that the tool-holder plate can be stopped in its second position for a determined time t which is introduced as an operating parameter in the input means.
  • the downtime is of the order of a few hundredths of a second.
  • Another difficulty encountered in cutters of the third type resides in the premature wear of certain members when the cutter turns idle, that is to say when there is no sheet on the cutting tool during displacement from the first to the second position of the tool-holder plate.
  • the cutting forces cause a slight deformation of the support cylinder and the tool-holder plate
  • it is usual to compensate for this deformation by ensuring that the space between the tool-holder plate and the cylinder d support is slightly less than the height of the cutting blades. Therefore, when the cutter turns empty, the force generated to cause this deformation is transmitted only to the cutting blades, which causes their wear.
  • the support cylinder is provided with a flexible coating, it is this which would suffer premature wear due to the action of the cutting blades.
  • the locating system which is arranged in front of the support cylinder and connected to the electronic control circuit is programmed to maintain the tool-holder plate in its first position in the event that it does not detect a sheet.
  • the cutting tool does not come into contact with the support cylinder when no sheet is detected by the tracking system in front of said cylinder.
  • Cutters of the third type are most often integrated into complete installations comprising a feeder and possibly printers.
  • the cutter drive mechanism is only part of the entire drive mechanism of the complete installation. Therefore it is not currently possible to have in a facility a cutter that would not have been designed to work with the rest of the facility.
  • the transfer means are equipped with an independent electronic servo motor which is connected to the electronic circuit.
  • control means are mounted on the sheet movement members at the previous station, said control means being connected to said electronic circuit. The latter is programmed so that on the one hand the speed of the transfer means is constantly equal to the speed of the sheet leaving the displacement members of the previous station and on the other hand the launching means are controlled as a function of said speed. so that the sheet has the same speed as the peripheral linear speed of the support cylinder when it arrives on the cutting tool.
  • the improved cutter of the invention can be arranged in an existing installation.
  • the cutter receives the sheets at the linear speed which is imposed by the previous station without this affecting the desired rate of the cutter.
  • the installation 1 shown in FIG. 1 is a printing and cutting installation one by one of sheets of corrugated cardboard.
  • This installation 1 comprises from upstream to downstream in the direction of movement of the sheet successively a feeder 2, a printer 3, the cutter 4, a box for evacuation of cutting waste 5 and the stacking station and reception 6.
  • the cutter comprises a transfer box 7 and a launch box 8, a support cylinder 9, a tool holder plate 10, which is driven in an alternating movement back and forth according to arrow F for the forward movement and the arrow F 'for the return movement.
  • the tool-holder plate 10 has longitudinal racks, not shown, and its reciprocating movement is obtained by the rotation of toothed wheels meshing in said racks. Said toothed wheels are driven by at least one motor 11 with electronic servo-control, of the brushless type.
  • the waste evacuation box 5 comprises a suction channel 12 at the immediate outlet of the cylinder 9 and a poses conveyor 13, which is placed beyond the suction channel 12 and which consists of rollers 14 arranged transversely by relative to the direction of movement of the sheet and separated from each other by free spaces.
  • suction means according to a first circuit leading to the suction channel 12, said first circuit corresponding to the evacuation of cutting waste 15, and a second suction circuit emerging in the poses conveyor 13.
  • the rollers 14 are rotated by means not shown. This rotation, as will be explained further in the following description, allows the evacuation of the poses towards the reception and stacking station 6.
  • FIGS. 2A to 2D illustrate the different stages of the operation of the cutter 4 when the tool-holder plate 10 passes from its first front position (FIG. 2A) to its second rear position (FIG. 2D).
  • a cutting tool 16 On the tool-holder plate 10 is fixed a cutting tool 16.
  • This cutting tool 16 On this cutting tool 16 are vertically mounted threads or cutting blades 17 according to the configuration of the profile to be cut.
  • This cutting tool 16 also includes tubing suction 18 and ejection bellows 19, which are distributed in each of the zones corresponding to a pose 20. This term designates each of the sheet portions which result from the cutting of the initial sheet.
  • the tool-holder plate 10 When the tool-holder plate 10 is in the first position, the most upstream of the cutting machine, it is located, like the cutting tool 16 under the transfer box 7 and under the launch box 8.
  • a cutting sheet 21 was fed from the previous station, for example the printing machine 3 in the example illustrated in FIG. 1. This sheet 21 is located astride the transfer box 7 and on the launching mat 8. It is directed obliquely towards the lower surface of the cylinder 9.
  • the tool-holder plate 10 has started to move in the direction of arrow F, the sheet 21 has itself moved under the action of the launch box 8 and the cylinder 9 has itself rotated by a certain angle. All these movements have been synchronized so that the front edge 21a of the sheet 21 comes precisely be applied to the front edge 16a of the cutting tool 16 when said sheet comes into contact with the outer surface of cylinder 9 .
  • This first step between the first position illustrated in the figure 2A and this intermediate position in FIG. 2B constitutes the step of launching the tool-holder plate 10.
  • the tool-holder plate 10 When it arrives in the position in FIG. 2B the tool-holder plate 10 must have acquired a speed which must be equal to the linear speed of the outer surface of the cylinder 9 which comes into contact with the sheet 21. The latter must also have acquired, thanks to the launching box 8, the same speed of movement.
  • the tool-holder plate 10 must keep the same speed of movement up to the position it has in FIG. 2C, that is to say when the rear edge 16b of the cutting tool 16 leaves the surface outside of cylinder 9.
  • the last step of the forward movement of the tool-holder plate 10 ends in the second position illustrated in FIG. 2D in which the cutting tool 16 is placed under the rollers 14 of the laying conveyor 13 after having passed under the channel d 'suction 12.
  • This phase corresponds to the deceleration of the tool holder plate 10 until it stops and before the return movement in the direction of arrow F'.
  • the height of the cutting tool 16 to the right of the cutting blades is equal to the spacing between the outer surface of the support cylinder 9 and the tool-holder plate 10 so that the sheet 21 gradually penetrates the blades cutting when it goes directly over the axis of rotation 22 of the cylinder 9.
  • the passage of the cutting tool 16 supporting the sheet 21 cut under the suction channel 12 allows the evacuation of cutting waste 15 through said channel 12.
  • the cut sheet which is on the cutting tool 16 when the tool holder plate 10 is in the second position illustrated in FIG. 2D is ejected from said cutting tool 16 by blowing compressed air through the ejection bellows 19 while the suction which was carried out through the pipes 18 is cut.
  • This ejection combined with the suction implemented in the conveyor 13 allows the plates 20 to be pressed onto the rollers 14. These are put in rotation so as to evacuate said blanks 20 towards the receiving and stacking station 6.
  • the tool-holder plate 10 is driven in its reciprocating movement by at least one independent motor with electronic servo-control with two directions of rotation 11.

  • the linear speed of the tool-holder plate must constantly be equal to the peripheral linear speed of the support cylinder 9 as long as the cutting tool 16 is in contact with the support cylinder 9. This condition can be achieved by instant monitoring of the rotation of the support cylinder 9 by the control means 23 and thanks to the knowledge of the length l of the cutting tool.
  • the electronic control circuit 24 is programmed so as to vary the amplitude of the return movement of the tool holder plate 10 as a function of the length l of the cutting tool 16. This amplitude will be all the more small compared to the maximum amplitude for which the machine has been designed, that the length l of the cutting sheet will deviate from the maximum cutting length L authorized by the machine.
  • the electronic control circuit 24 is programmed so that the drive motor 11 drives the tool-holder plate 10 during the return movement of the latter according to a simple law composed of an acceleration, immediately followed by a deceleration , so that the duration of the return movement is less than that of the forward movement. It is therefore possible to increase the production rate, without modifying the cutting conditions, during the forward movement of the tool holder plate 10.
  • the cutting machine 4 also includes a system for locating the position of a predetermined element of the sheet 21, which is located upstream of the support cylinder 9. It is for example a position sensor 26 capable of detecting the front edge 21a or optionally back of the sheet 21 to be cut.
