Claims
- 1. An installation for automatically cutting sheets of material, said installation comprising:
- a plurality of stacking devices for stacking said sheets to be cut, said stacking devices including
- an outlet end, and
- a first electrical connection assembly, said first electrical connection assembly including
- an indexing element,
- a first connector portion, and
- mounting means having a set of two moving supports for enabling said indexing element and said first connector portion to move in two orthogonal directions, said first connector portion and said indexing element being mounted on said mounting means; and
- at least one cutting device, said cutting device including
- a second electrical connection assembly for cooperating with the first electrical connection assembly when the cutting device is in register with a corresponding stacking device, said second electrical connection assembly including
- a first connector portion, and
- a cam assembly, said cam assembly cooperating with said indexing element of said first electrical connection assembly for adjusting the position of said second electrical connection assembly along a displacement direction of the cutting device relative to the first electrical connection assembly of the corresponding stacking device,
- said cutting device further including
- a bench having a feed end, said feed end including means for mating with the outlet end of the stacking devices, a bench outlet end for unloading said sheets that have been cut out, and a top surface extending from said feed end to said bench outlet end, that defines a cutting zone,
- a support means which is displaceable with respect to said bench, said support means having a surface that faces the feed end of said bench,
- a cutting head mounted on said surface of said support means facing said feed end,
- a cutting conveyor and unloading conveyor, both conveyors being mounted beneath said top surface of said bench,
- turbine means for creating suction, said turbine means being disposed beneath said unloading conveyor, and
- means for supporting at least one roll of impermeable film, said supporting means being mounted about said top surface of said bench, substantially at the feed end of said bench, before said cutting head.
- 2. An automatic cutting installation according to claim 1, wherein said means for supporting rolls of film comprise means for simultaneously supporting two rolls.
- 3. An automatic cutting installation according to claim 1, in which a support sheet is placed on the cutting zone beneath a stack of the sheets to be transferred, the installation further including, between the feed end and the cutting zone, a zone for receiving the stack of the sheets to be cut, said zone being of lesser length than width and being provided with perforating means for perforating said support sheet as said support sheet advances together with said stack of the sheets in a displacement direction towards the cutting zone.
- 4. An automatic cutting installation according to claim 3, wherein said perforation means comprise a cylinder with perforation tools on a lateral face, said cylinder being mounted for free rotation about a horizontal axis perpendicular to the displacement direction of the stacks of sheets, and means for displacing said horizontal axis of said cylinder between an active position in which said cylinder perforates the support sheet and an open position in which it is possible to insert said support sheet.
- 5. An automatic cutting installation according to claim 1 wherein the turbine means include control means for producing a first level of suction and a second level of suction, higher than the first level of suction, the second level of suction used during the operation of cutting by said cutting head.
- 6. An automatic cutting installation according to claim 1, wherein said stacking devices are disposed parallel to one another, and further comprising means for guiding displacement of said cutting device perpendicularly to said stacking devices, means for controlling the displacement of said cutting devices, and means for stopping said cutting device successively in register with each stacking device.
- 7. An automatic cutting installation according to claim 1, wherein said turbine means for creating suction comprises:
- a turbine having an outlet,
- silencer means,
- a first duct for connecting the outlet of said turbine to said silencer means,
- a motor for driving said turbine,
- means for lowering the temperature of the air arriving at the silencer means from the outlet of said turbine comprising fan means for cooling said motor and a second duct for connecting said fan means to said first duct.
