  • the installation essentially comprises a cutting machine proper 10 and a so-called quilting table 12.
  • the quilting table is used to make a prior stacking of different sheets, in particular of textile materials, to perform a simultaneous cutting of parts from all of the stacked leaves.
  • the cutting machine 10 comprises a frame 14, the upper surface of which constitutes the working face.
  • On the working face there is successively a feed conveyor 18 which is used to transfer the sheet mattresses from the feed end of the machine to the next area referenced 20 which is the actual cutting area.
  • the useful length of this zone is indicated by L.
  • a cutting conveyor 24 which is used to drive the stack of sheets during the cutting operation when the length of the sheet is greater than the length useful for cutting the machine L.
  • the cutting is carried out using a cutting 22 which is mounted on displacement means and in particular a gantry 26 which moves along the length of the cutting zone, the cutting head 22 being able to be moved along the length of the gantry 26.
  • an unloading conveyor 30 which is used to transfer the stacks of sheets once they have been cut.
  • the installation also includes inside the frame 14 a turbine suction device 32.
  • This suction installation is used to create a vacuum at the level of the conveyor 24 to ensure the driving of the stacks of sheets and to keep the sheets stationary. to be cut during the cutting phase. It should also be specified that in order to obtain good suction efficiency, it is generally necessary to have a film of waterproof material above the stack of sheets to be cut.
  • the film of impervious material which is stored in the form of a roll 32 is mounted on a roll holder 36 arranged in the middle zone of the feed conveyor 18.
  • Document US-A-4 328 726 describes an automatic cutting machine for stacked sheet materials in which the cutting table has large feeding and unloading zones on either side of the actual cutting zone at above which the cutting head moves. This machine therefore has a large size.
  • An object of the present invention is to provide an installation for cutting sheet materials of the type described above which has a reduced bulk compared to the machines of the prior art and makes it possible to optimize the use of consumables (support paper , waterproof film ).
  • Another object of the invention is to provide a cutting installation which has a reduced sound level.
  • Another object of the invention is to provide a cutting installation of the type mentioned above which facilitates the interventions of the personnel during the manual operations to be carried out and to automate the transfer of material from the depositing machine to the cutting machine. .

  • the frame has an upper face which defines from its feed end up to '' at its discharge end a first zone for partially placing the stack of sheet to be cut, said zone having a reduced length, a cutting zone below which the suction cutting conveyor and a vacuum conveyor are mounted unloading, in that the turbine means for creating the suction are arranged below the unloading conveyor, in this that said cutting head is mounted on the face of the displacement means turned towards the supply end of the frame and in that means for supporting at least one roll of waterproof film are mounted above said upper face of the frame substantially at its feed end.
  • the length of the cutting device which will later be called a cutter, is significantly reduced due to the elimination of the feed conveyor which is replaced by a zone for partially placing the stack of sheets whose length is reduced.
  • the feed conveyor which is replaced by a zone for partially placing the stack of sheets whose length is reduced.
  • sufficient space is freed up to allow easy manual positioning of the stack of cut sheets and waterproof film.
  • the cutting machine furthermore comprises in the zone for placing means to perforate the support sheet as it advances with the stack of sheets to be cut.
  • This characteristic makes it possible to supply the quilting table with non-perforated support sheets (in particular of conventional type paper), to carry out the deposition of the stack of material on the support sheet, to transfer by levitation by means of a cushion. of air under the support sheet, impermeable to air, said stack towards said perforation means where the support sheet is made permeable to air in order to allow, subsequently at the level of the cutting zone, the suction of air through the pile between the support sheet and an airtight film arranged above the stack.
  • the operating cost of the machine is reduced accordingly due to the less expensive nature of non-perforated support sheets.
  • Another advantage which results from this resides in the improvement of the conditions of transfer of the stack between the quilting table and the cutting table insofar as the prior art provided that the support sheet was fed in perforated form and therefore permeable, which was detrimental to the quality of the lift.
  • the suction means by turbine comprise control means for producing a first suction level when using the conveyors and a second suction level higher than the first during the cutting operation. using the cutting head.
  • This arrangement allows on the one hand to reduce the electrical energy consumption linked to the supply of the suction turbine by providing a maximum operating speed only during the effective cutting period. On the other hand, this arrangement makes it possible to reduce on average the noise level resulting from the operation of the suction turbine. Finally, this arrangement makes it possible to use, for the drive of the cutting conveyor, a motor of lower power than that which is usually provided, which reduces the electrical consumption.
  • the cutting installation comprises a plurality of fixed stacking devices or quilting tables which are arranged parallel to each other and a single cutting device or cutter, means for guiding the movement of the cutting device perpendicular to the stacking devices, and means for controlling the movements of the cutting device and its stop successively in front of each stacking device.
  • this embodiment of the invention is particularly advantageous since it makes it possible to use only a single cutter, the cost of which is very substantially greater than that of the quilting tables in cooperation with a plurality of tables. quilting, which also makes it possible to prepare suitable stacks of sheets on each quilting table when the cutter works in cooperation with another quilting table.
  • the installation comprises on the one hand a cutting device or cutter 40 and on the other hand a quilting table or stacking device 42.
  • the cutter 40 comprises an elongated frame 44 having a feed end 46 and a unloading end 48.
  • the upper face of the frame 44 which is referenced 50 defines on the one hand a zone for depositing the front end of the sheet mattresses 52, then a cutting zone 54 of useful length L, then a zone of unloading 56 essentially constituted by an unloading conveyor 58.
  • a suction cutting conveyor 60 as well as the cutting head 62 have also been shown below the cutting zone 54.
  • This cutting head 62 is mounted on support and displacement means essentially constituted by the gantry 64 which moves according to the direction of the length of the frame in the cutting area.
  • the cutting head 62 is movable in the direction X perpendicular to the direction of the length of the frame.

  • FIGS. 2 and 3 a structure 68 has also been shown for supporting two rolls of waterproof film 70 and 72.
  • the two rollers are mounted in the same vertical plane and are parallel to each other. Either the two rollers 70 and 72 are identical, which allows the replacement of one roller during operation while the other is in use, or these two rolls of waterproof film have different widths for cutting sheets of different width possibly in combination with a device for reducing the useful cutting surface such as a mask of flexible material on the unused part of the cutting zone.
  • FIGs 2 and 3 there is also shown in a simplified manner a device 74 for perforating a sheet of paper intended to facilitate the movement of the sheet mattresses on the quilting table, while subsequently allowing the passage of the air sucked in at the cutting area to maintain the pile.
  • the chimney 80 for output of the suction system 66 has been shown in a simplified manner.
  • the length of the cutting machine is very significantly reduced since this conveyor is replaced by a simple zone for depositing the front part of the stack of sheets, the length can be very short.
  • the support structure of the rollers 68 is disposed at the feed end 46 of the machine and that, the cutting head 62 being turned towards the feed end, it is not no longer necessary to pass the material under the movable assembly 64 for the initial positioning of the stack of sheets to be cut. This makes it easier for the operator to place the cutting mat on the cutting conveyor.
  • FIG. 4 we will describe a preferred embodiment of the suction assembly.
  • a suction pipe 80 which opens into the frame 44 and allows to put under vacuum the cutting conveyor 60 and therefore the cutting zone 54.

  • the outlet of the turbine is connected to line 86, itself connected to a silencer not shown in the figure.
  • the turbine 82 is driven by a preferably electric motor 88 via a transmission system 90 of conventional type.
  • the electric motor 88 can be controlled by the associated control circuit 92 so as to be able to rotate at at least two different speeds.
  • Either the control system comprises a frequency converter which thus makes it possible to vary the speed of rotation of the motor 88 and, consequently, the suction level of the turbine 82, or the motor 88 comprises two separate windings and the circuit of control 92 allows the switch to connect either of the two motor windings to the power supply.
  • the electrical consumption and the sound level associated with the motor 88 driving the turbine 82 are lower due to the reduction in speed of said motor 88 during the low vacuum phase.
  • the suction device also includes means for reducing the temperature of the air at the outlet of the turbine. Indeed, without special precautions, the air outlet temperature is around 80 ° C.
  • Another objective is to reduce the thermal shocks applied to the drive motor 88 of the turbine and also to reduce the temperature of the air discharged outside and therefore the nuisance that it can create.
  • This additional device bearing the general reference 94 consists essentially of a pipe 96 which recovers the air driven by the fan 98 of the motor 88.
  • this pipe 96 an additional fan 100 is provided.
  • the air thus leaving the pipe 96 has a temperature of the order of 40 ° C.

  • the cover 118 is lowered and the perforation device is therefore in the active position. It is understood that the sheet of paper 110 is driven at the same time as the sheet mattress, referenced 124 in FIG. 6. The entrainment of the paper simultaneously causes the rotation of the cylinder 112 and therefore the progressive perforation of the paper 110.
  • This characteristic of the cutter makes it possible to use a paper of conventional type whose cost is significantly lower than that of a pre-perforated paper and above all to improve the transfer of the stack to an air cushion at the level of the quilting tables.
