Definitions

  • This patent application for industrial invention relates to a method and its relative machine for stitching, with continuous automatic cycles, several superimposed layers of different material, even of remarkable thickness, by seams before closed paths and delineating finished figures, which are centered and executed several times on a strip of fabric.
  • the method and the machine according to the invention provide a remedy, since the stitching of the padded fabrics, by seams delineating closed and finished figures, is carried out with rapid continuity by a fully automatic cycle. .
  • the machine in question comprises a fixed frame (1) for supporting the various rolls of material, four in number in this case.
  • the four coils are unwound horizontally simultaneously using a clamp (2) which transversely tightens the edges of the four strips placed on top (la), (1b), (le) e (Id).
  • This clamp is mounted on a rolling carriage on horizontal slides, adjustable in the course, so that the length of the strip of fabric can be varied.
  • the sewing station (3) which basically consists of a traditional machine for stitching, attached to a mobile structure on a horizontal plane in two orthogonal directions, so that one can practically ment travel any curvilinear trajectory.
  • two transverse grippers (4) and (5) are both provided, respectively, stationary.
  • second consists, in turn, of two transverse clamps (5a) e (5b), placed a short distance from each other, between which can act a cutter (6).
  • the clamp (4) and the clamp (5b) are closed for the moment and they tighten the four superimposed strips (la), (1b) (1c) and (Id), whose transverse edges are just in correspondence of the plane cutting cutter (6), a short distance from the gripper gripping area (5a), which during this phase is open.
  • the movable clamp (2) is stopped, at the end of the stroke, and it clamps the cut edge of the strips, near and beyond the clamp (5b).
  • a reader automatically gives the opening command to the clamps (4) and (5b) and the reversing command to the support carriage of the clamp (2), which, moving back, unrolls rollers at the same time respective les (la), (1b), (1c) and (1d).
  • a micro-switch at the end of the stroke simultaneously closes the pliers (5a) and (Sb) and slightly in advance the pliers (4) so that the strip of strips runs out. lée is placed in slight tension between the clamp (4) and the clamp (Sb), in order to eliminate the possible undulations which would make difficult and in any case imprecise sewing fabrics.
  • This same end-of-travel microswitch gives the setting command, in the process of being carried out by the sewing machine and simultaneously to the cutter (6) which, by advancing between the pliers (Sa) and (5b), closed, cuts the four transversely overlapping and already stitched.
  • Another end-of-travel microswitch opens the clamp (2) and the clamp (5a), so that the strip of fabric already sewn, paraded from the sewing surface during the above-mentioned backward stroke of the carriage, falls on the ground, on the sheet cut in the immediately preceding cycle.
  • the carriage begins its run forward until it stops near the clamp (5b) where it grasps the edge of the four strips, which has just been cut, and where he remains waiting for the end of the sewing phase, ready to make a new race backwards and therefore to start a new cycle of execution.
  • the clamp (2) comprises a transverse bar (20), under which is welded, at regular intervals, legs (20a) cooperating with as many corresponding and underlying legs (21a), welded to a bar (21) below the bar (20).
  • the bar (20) and the bar (21) are both supported horizontally at the two ends by two carriages (22), rolling on longitudinal guide rails (23), dragged by chains (24) meshing with drive gears (251.
  • the bar (21) is welded between the carriages (22), while the bar (20) is embedded between them on two end pivots, which project externally, on which a small radial lever (26) is fixed. ), actuated by a small pneumatic piston (27).
  • the longitudinal guide rails (23) are supported by a square quadrangular base (28) on the face of which the cutter (6) has been fixed which acts between the clamps (5a) and (5b).
  • the spacing of the empty spaces between one pallet and the other is equal to the distance between the pair of legs (20a-21a), which, when the carriages (22) are completely forward, slide in and stop between one pallet and the other, catching the strips beyond the pallets (51b).
  • transverse currents (50a) and (50b) are respectively attached to a pair of support brackets (53a) and (53b), connected by connecting rods (54a) and (54b) and set up above the horizontal transverse ( 55) of a support gantry (56), fixed to the base (28).
  • the lifting and lowering of the pallets (51a) and (51b) occur thanks to the two small pneumatic pistons (57a) and (57b) which act respectively on the connecting rods (54a) and (54b).
  • a carriage (60) is provided, rolling transversely on a horizontal guide rail (61), dragged by a chain (62) , meshing with the driving gear (63).
  • the opening of the clamp (2) and of the clamp (5b) is controlled by the same microswitches which stop the motor (M62) at each end of travel of the carriage (60).
  • clamp (4) it is produced in accordance with the structure of the clamps (5a) and (5b).
  • the sewing machine (35) is fixed under the cross-member (30) of a vertical gantry, the straight feet (31) of which are mounted on two carriages which can roll on two sections of longitudinal rails ( 32) and also rolling on two sections of transverse rails (33).
  • the motor (ML) is also installed, which activates an imprint crown which meshes with a fixed rack (34), before a linear development conforming to the outline of the puncture design.
  • the method and the machine according to the invention are particularly suitable, for example, for the stitching of the padded fabric which is used to coat the mattresses.
