Definitions
- the present invention relates to a machine for automatic cutting of sheet materials. More specifically, the invention relates to a machine for cutting stacks or mattresses sheets of materials, including textile materials, using a cutting head.
- the loading area is used to perform a prior stack of different sheets, for example textile materials, to perform a simultaneous cutting of parts in all the stacked sheets.
- a cutting conveyor for driving the stack of sheets during the cutting operation.
- the cut is made using a cutting head which is mounted on means of displacement relative to the table and in particular on a gantry which moves along guides arranged along the length of the cutting zone, the cutting head can translate according to the length of the gantry.
- the unloading area is used to transfer stacks of sheets once they have been cut.
- the machine also comprises, inside the frame of the table, a suction device for establishing a strong depression at the cutting conveyor up to 200 mbar.
- This suction device thus makes it possible to keep the leaves to be cut immobile during the cutting phase.
- it is generally necessary to have a film of impervious material above the stack of sheets to be cut.
- the table frame of this type of cutting machine is subject to significant deformations structural.
- the guides along which the gantry moves can be deformed to the point of being twisted. This also causes a deformation of the gantry resulting in friction and loss of precision in the movements of the cutting head and premature wear of these elements.
- Another disadvantage of these deformations is the accelerated fatigue of the general structure of the cutting machine causing a shortening of its life.
- the main object of the present invention is to overcome such disadvantages by increasing the strength of the general structure of the cutting machine without increasing its weight and therefore its cost, transport and installation costs.
- an automatic sheet material cutting machine comprising a table having a cutting area, a cutting head mounted on moving means with respect to the table, a cutting conveyor housed inside. a box disposed below the cutting zone, and means for establishing a vacuum in the box, and wherein, in accordance with the invention, the box is curved outwardly at least in its lower part which is opposite to the cutting area.
- the lower part of the box can be curved towards the outside of the box in cross section and substantially straight in longitudinal section.
- the box is bulged outwards in its lower part which is opposite to the cutting zone and in its transverse parts.
- FIG. 1 is a schematic view of a cutting machine according to one embodiment of the invention.
- FIGS. 2 and 3 are partial views and perspective of the cutting machine of Figure 1; and - Figure 4 is a cross-sectional view of the cutting machine of Figure 1.
- the automatic sheet material cutting machine consists of a table 10 having a frame 12 of elongate shape.
- the upper face of the frame 12 defines a cutting zone 14, a zone 16 for loading sheet material to be cut upstream of the cutting zone, and a zone 18 for discharging cut pieces downstream of the cutting zone.
- a gantry 20 fixed to the frame 12 is able to move along guides 21 arranged along the length of the cutting zone 14.
- This gantry carries a cutting head 22 which is movable according to the length of the gantry.
- the cutting head 22 can reach any point in the cutting zone 14.
- the cutting machine also comprises a cutting conveyor 24 which is housed inside the frame 12 of the table 10 under the zone of cut 14.
- the cutting conveyor 24 serves to drive the sheet to be cut
- the cutting conveyor 24 is housed, with the exception of its horizontal upper surface delimiting the cutting zone, inside a box
- the 26 is sealed to the frame 12 of the table 10.
- the box 26 is connected to a turbine suction device 28 also mounted inside the frame 12 of the table 10.
- the cutting conveyor 24 consists of blocks 24a between two passages communicating the interior of the box 26 with the surface of the table 10.
- the blocks 24a comprise a base from which project a plurality of filiform elements.
- the casing 26, of substantially parallelepipedal shape extends longitudinally over at least the entire length of the cutting zone 14. It consists of a lower face 26a opposite the surface of the table 10, two transverse faces 26b and two longitudinal faces 26c which can be formed by the frame 12 of the table 10.
- a duct 27 makes it possible to connect the turbine suction device 28 to the box 26, for example at one of its transverse faces 26b.
- the turbine suction device 28 serves to create a depression inside the casing 26 in which the cutting conveyor 24 is housed.
- the sheet In order to obtain a good suction efficiency, it is also possible to cover the sheet to be cut with a flexible film of airtight material.
- This can be stored as one or more horizontal rollers which are mounted on a roll holder 32 disposed at the upstream end of the table 10.
- the roll holder 32 is fixed to the frame 12 of the table.
- a stack of sheets to be cut may be previously made, for example on a quilting table 34 disposed upstream of the table 10. Alternatively, the sheets can be cut one by one. The stack of leaves to be cut is then transferred to the table
- the airtight film is pulled from the roll or rollers 30 and is deposited on the stack of sheets to cover it completely.
- the stack of sheets covered by the airtight film is advanced on the table 10 under the driving effect of the cutting conveyor
- the stack of sheets is cut by means of the cutting head 22 mounted on the frame 20.
- the cutting head is controlled to follow a predetermined path.
- the stack of sheets covered with the waterproof film is firmly held on the table by the depression of the box 26.
- an unloading table 36 can be arranged for this purpose downstream of the table. 10.
- the box 26 inside which the cutting conveyor 24 is housed is bulged outwards at least in its lower part (that is to say in its part which is opposite to the zone cutting 14).
- the box is bulged outwards in its lower portion 26a opposite to the cutting zone 14 and in its transverse portions 26b.
- FIGS. 2 to 4 which partially show the table of the cutting machine according to FIG. 'invention. It should be noted that for the sake of clarity, the cutting conveyor 24 of the table is only partially represented in FIG. 2.
- both the lower face 26a which is opposite to the surface of the table and the transverse faces 26b of the box 26 have a rounded outwardly of the box.
- the lower face 26a of the box is curved (or curved) towards the outside of the box in cross section ( Figure 4) and substantially straight in longitudinal section ( Figure 1).
- the underside of the box could be substantially straight in cross section and curved outwardly of the box in longitudinal section.
- the curved shape of the box can be made from walls that are either fully curved or obtained by a succession of flat facets forming between them a rounded.
- the degree of curvature of the curved parts of the box depends on several parameters such as the desired level of depression inside the box, the dimensions of the box, the dimensions of the cutting table, etc.
- the box 26 could also be bulged outwards at its longitudinal faces 26c.
