Machine for cutting sheets by fluid projection
A machine for cutting sheets by fluid projection is provided. The machine has a head displaceable in three dimensions, arranged on a support table for supporting sheets to be cut, in which there is a hole for the passage of the cutting fluid, the support table being formed by a set of rollers distributed in two groups of rollers and which determine therebetween the hole, being arranged at the entrance to the support table feed rollers provided with rotary drive action, between which a step for introducing the sheets is determined, in movement on the support table, while a synchronization belt is arranged in relation to one end of the rollers and has displacement drive action combined with the rotary drive action of the feed rollers.
1. A machine for cutting sheets by fluid projection comprising
a support table for supporting sheets to be cut, the support table comprising two pair of carrier belts and a plurality of rollers distributed into a first set of plurality of rollers and a second set of plurality of rollers, and a through-hole between the first set and second set of plurality of rollers;
a cutting fluid projection head equipped with Cartesian movement configured to move in three dimensions, the projection head arranged above the support table and over the through-hole;
feed rollers located at one end of the support table configured to receive the sheets to be cut, the feed rollers provided with rotary drive action;
a synchronisation belt arranged at one end of the plurality of rollers, the synchronization belt being in contact with the plurality of rollers and having a displacement drive action combined with a rotary drive action of the feed rollers,
wherein the plurality of rollers are assembled in a free-rotating assembly between the two pair of carrier belts, and
wherein the plurality of rollers between the two pair of carrier belts are equipped with independent displacement drive action.
2. The machine for cutting sheets by projecting fluids according to claim 1 , wherein the synchronisation belt is related to the rollers of the support table by means of a transmission by engagement.
3. The machine for cutting sheets by projecting fluids according to claim 2 , wherein the synchronisation belt is configured so that it is engaged with the plurality of rollers of the machine.
4. The machine for cutting sheets by projecting fluids according to claim 1 , wherein the synchronisation belt is related to the rollers of the support table by means of transmission by friction.
5. The machine for cutting sheets by projecting fluids according to claim 1 , wherein the supporting table has two ends and further comprises additional two pair of carrier belts, a third set of plurality of rollers and a fourth set of plurality of rollers arranged respectively at both end of the support table, and wherein the third set and fourth set of plurality of rollers are assembled in a free-rotating assembly between the additional two pair carrier belts.
6. The machine for cutting sheets by fluid projection according to claim 1 , wherein connection elements are arranged between the carrier belts and the rollers that enable the movement of the carrier belts to be transmitted to the rollers.
7. The machine for cutting sheets by fluid projection according to claim 1 , further comprising additional two pairs of carrier belts wherein one of the carrier belts of the pair of carrier belts is arranged above the first set of and second set of plurality of rollers, while the additional two pairs carrier belts is disposed below the first set of and second set of plurality of rollers.
8. The machine for cutting sheets by fluid projection according to claim 1 , wherein the plurality of rollers that make up the support table are arranged in assembly between the same carrier belts equipped with displacement drive action.
9. The machine for cutting sheets by fluid projection according to claim 1 , wherein on the plurality of rollers a band is incorporated, which is displaced by the movement of the plurality of rollers, a body of the plurality of rollers being toothed to engage with an inner teeth of the band.
10. The machine for cutting sheets by fluid projection according to claim 9 , further comprising at least one end roller that carries the band to an end of the machine through which pieces resulting from the cuts made in the sheet leave the supporting table.
11. The machine for cutting sheets by fluid projection according to claim 9 , wherein between an initial roller and a final roller and corresponding adjacent rollers there is a space that avoids a possible collision between the plurality of rollers.
12. The machine for cutting sheets by fluid projection according to claim 1 , wherein a transverse conveyor belt formed by a grid structure is arranged below a cutting area.
