Definitions

  • the invention relates to a method and a device for gripping flexible layers, in particular textile, knitted, woven or other layers; it extends to a machine allowing the transfer of these layers from a stack or several stacks where said layers are stored in superimposed positions, to one or more other locations.
  • a gripper of the latter type is described in French patent application FR-A-2 468 531, in the application for certificate of addition FR-A-2 482 064 or in patent DE-A-3 101 705.
  • the gripping of the flexible layer is carried out by means of two needles which come out of a casing by crossing each other to penetrate obliquely into one or more flexible layers of the stack: by the effect of their crossing, these needles have an action retaining the layer or layers in which they are embedded.
  • the present invention proposes to remedy the aforementioned faults of known gripping devices. It aims to provide a new gripping device in which the gripping is ensured by means of a needle, under conditions suitable for eliminating all the defects of known grippers and in particular of grippers with crossed needles and grippers with curved needle rotating around from their center of curvature.
  • One objective of the invention is in particular to simultaneously obtain the three essential qualities for good operating reliability: secure grip of the layer or layers to be gripped, assured take-off of this layer or of these layers relative to the lower layers, safe release of this layer or these layers in order to deposit them.
  • Another objective is to achieve these results with a space-saving gripping device, of simple structure and of low cost.
  • Another objective of the invention directly linked to the previous ones (reliability, low cost, reduced bulk) is to provide a machine for gripping and transferring textile pieces, allowing, by means of several grippers, to grip and transfer with excellent reliability, parts of all shapes and sizes.
  • the present invention solves the problem posed by this apparent incompatibility and relates to a method and a needle device which is capable both of allowing a firm grip of one or more thin layers and an assured takeoff of the lower layer which must be left on the spot.
  • the method proposed by the invention is of the type comprising the following operations (known in themselves in particular by patent DE-A-3101 705):
  • Such a method can be implemented using a curved needle with a concavity oriented in the same direction as that of the trajectory T; but it can also be implemented by means of a needle of different shape, in particular rectilinear, partially rectilinear or forming an angle.
  • a needle having an end provided with at least one point and, upstream of the latter, a stopper adapted to come into stop against the flexible layer; this retainer ensures or considerably increases the pushing action on the fabric of the upper layer and notably generates or facilitates the formation of the ripple in the fabric.
  • the method of the invention leads to forming an undulation of the layer to be gripped inside the perforated part of the bearing surface, to stitch this undulation and to block it at the entrance of the groove of the head, the tissue being, at the end of movement of the needle, pinched at its undulation between said needle and the inlet of said groove.
  • the grip which is carried out by all the fibers with pinching of a small portion of the fabric, is extremely firm and the experiments have shown that the risks of detachment were negligible even in the case of the most layered fabrics. fine.
  • the gripping of the fabric by pricking and pinching a ripple formed thereon is compatible with a displacement of the needle (relative to the bearing surface) such that the trajectory of its end is very flat; under these conditions, it is easy to adjust the height of this movement so that a single layer or a determined number of layers is entered.
  • the latter is blocked relative to the bearing surface and it is kept blocked during the relative spacing movement between the stack and the needle assembly /bearing surface.
  • this air blowing is carried out by simple nozzles arranged above the layers, without the need for hollow needles as in the case of the crossed needle process.
  • the detachment of this layer is obtained without difficulty, by subjecting each needle to a reverse displacement relative to its bearing surface, so as to bring back each of said needles in its initial position set back relative to the bearing surface.
  • the layer or layers which are no longer held apart deviate by gravity from the bearing surfaces to fall into the desired location.
  • the method of the invention is thus not subject to the release difficulties encountered by adhesive grippers and grippers with hanging strips.
  • the needle has an end provided with at least one point and, upstream of the latter, a stop adapted to come into abutment against the flexible layer; in particular said needle advantageously comprises two separate points, the retainer being formed by the part situated between the bases of said points.
  • the gripping device shown by way of example in FIGS. 1 to 4 comprises a frame 1 which carries around a central region -la- several assemblies 2, the structure of which is described in detail below.
  • the number of sets 2 and their distribution depend on the shape and dimensions of the textile pieces to be gripped (which will be designated below by "pieces of fabric" whatever their knitted, woven or other texture).
  • these sets may be four in number, two by two opposite, so as to grip each part in the vicinity of an angle.
  • chassis 1 can be associated with transfer means, making it possible to drive it between several locations where the parts are to be grasped or deposited.
  • the chassis 1 is equipped with air blowing means in a substantially vertical direction (or a secant direction relative to the horizontal plane).
  • air blowing means comprise a support 3 oriented downwards and pierced at its end with a channel 4 to which is connected a flexible air intake duct 5; the air emerges from the channel 4 through an orifice 4a oriented downwards.
  • Each set 2 comprises a plate 6 positioned in a roughly vertical plane; this plate is articulated by two needle screws such as 7 on two legs of the chassis 1 so as to be able to undergo relative to this chassis tilting movements of small amplitude around a horizontal axis passing through the screws 7.
  • the plate 6 is associated with drive means adapted to drive it in rapid round-trip movements, in rotation around the screws 7.
  • these means are made up, on the one hand, by a single-acting cylinder 8 having a movable projecting rod 8a which bears against the lower part of the plate 6, on the other hand, by a return spring 9 acting on the upper part of said platinum.
  • Supports 10 and 11 secured to the chassis 1 allow the mounting of these means in appropriate positions.
  • the plate 6 supports the body 12a of a double-acting pneumatic cylinder 12, by means of a lug 13 integral with said plate and forming an projection relative to the chassis 1.
  • the body 12a of the cylinder is fixed on the lug 13 as shown in Figures 1 and 2, so that the movable rod 12b of said cylinder is directed downwards in a substantially vertical position.
  • the jack 12 is associated with a proximity sensor 26 of a type known per se (in particular magnetic) which detects the high position of its piston and then delivers a control signal, causing the latter to lock in this position.
  • a proximity sensor 26 of a type known per se (in particular magnetic) which detects the high position of its piston and then delivers a control signal, causing the latter to lock in this position.
  • a gripping head 14 is screwed onto the end of the rod 12b of the pneumatic cylinder 12.
  • This head is formed by a cylinder portion with a horizontal lower base 14a, called to play the role of a support surface for the tissue to be grasped. Said head is partially split, by a fine groove 15 of thickness slightly greater than that of a puncture needle of the conventional type; this groove extends in a plane (vertical) substantially perpendicular to that of the support surface (horizontal) and opens along a diameter of said support surface.
  • the head 14 has an openwork part 16, in the example of circular section, which also opens onto the bearing surface 14a and extends on either side of the plane containing the groove 15. (In l 'example, this perforated part 16 is formed by the extension of a threaded hole which allows the head 14 to be screwed onto the jack rod 12b).
  • the head 14 carries a finger 27 which slides in an appropriate notch 6a of the plate 6, in order to avoid rotation of said head on itself (around its vertical axis) and to ensure guidance of that -this during its vertical translational movement.
  • the plate 6 carries a support 17, which is fixed on the latter in a position offset transversely relative to the head 14; this support is fixed on the plate by means of a stud 18 and a tubular spacer 19, which allow it to be assigned a relative preset position relative to said plate.
  • This support 17 carries a hinge pin 20 about which a link 21 can pivot; this axis 20 offset transversely with respect to the axis of the head 14 is located above the bearing surface 14a.
  • Elastic means are associated with the link 21 and arranged to urge the latter in the direction of its spacing with respect to the head, towards an extreme position where it abuts against the support 17 (position of FIG. 1).
  • these elastic means consist of one end 22a of a spring 22, which comes to bear on the link 21; this spring is wound around the tubular spacer 19 and its other end 22b is locked in a hole in the plate 6.
  • the link 21 is pierced with a lumen for the passage and fixing of a curved needle 23.
  • This needle of the conventional needle pricking type, comprises, opposite its point 23a, a heel 23b which is housed in the above-mentioned light of the link 21 and locked in the preset position by a pressure screw 24.
  • the means for positioning the needle are arranged so that (apart from the thicknesses) said needle is located in the plane of the groove 15 of the head and can move in this plane relative to the head, by rotation of the rod 21 about its axis 20; the concavity of said needle is oriented upwards and its center of curvature is located between the axis of articulation 20 and the vertical axis of the head, in a position closer to this vertical axis so as to be very much offset relative to axis 20.
  • the needle 23 passes through a guide lumen 25a formed in an element integral with the head (in the example a plate 25 fixed at the edge thereof in a preset position).
  • This guide light 25a and the positioning means already mentioned impose at all times the relative position of the needle relative to the head and are adjusted so as to give it the movements which are detailed below.
  • FIGS. 5 and 6 show respectively an intermediate position of the needle and its link relative to the head 14 and the final position of attachment of the fabric.
  • the combination of the above-mentioned movements leads the needle tip 23a to move on a path T as shown diagrammatically in FIG. 7b.
  • This trajectory of the needle tip 23a is considered relative to the head, that is to say taking this head 14 as a reference.
  • the needle In all positions, the needle is above the trajectory T: the direction of its point (tangent to the point) is located above the tangent to the trajectory and makes an angle with the latter of the order of a few degrees at 20 °.
  • FIGS. 7a to 7g illustrate the relative movement of the needle relative to the head 14.
  • the needle 23 is positioned so as to be situated initially set back in the groove 15 as shown in FIG. 7a.
  • the head is in the low position and the jack 12 which carries it is in the open air, which leaves the head free to rise with constant and low friction forces.
  • the link 21 is in the extreme stop position and the needle is in contact with the upper edge of the guide light 25a.
  • the stacking symbolized at E in the diagrams is caused to move upwards according to the arrows F in FIG. 7a, until its upper layer S comes into contact with the bearing surface 14a of the head.
  • the latter is raised and tends to retract upwards under the thrust of the stack; the pressure of the bearing surface on the stack is substantially constant and low enough not to significantly compress the layers and in particular the upper layer (due to the constant friction forces and low value of the jack 12).
  • the needle At the start of the retraction of the head, the needle has relative relative to said head a vertical downward relative movement until it comes to bear against the lower edge of the guide light 25a: its point then begins to move on the portion Ti of the trajectory until it comes into contact with the layer S as shown in FIG. 7b.
  • the spring 22 confers good flexibility on the movement of the needle and conditions a substantially constant penetration pressure of the needle.
  • the angle a of penetration (that is to say the angle defined by the direction of the end of the needle and the plane of the tissue) is between approximately 15 ° and 35 °, which guarantees correct penetration of the needle end through the fibers of the fabric.
  • This angle of penetration a is different from the angle formed by the tangent to the trajectory Ti (a> ⁇ ) at the same point, because the displacement of the point is not constituted by a rotation around the center of curvature of the needle; it follows that the movement of the needle is not limited to a rotating component, but has a component in translation constituted by a sliding towards the axis of the head 14, sliding which causes a push on the fabric in direction of this axis.
  • the angle B formed by the tangent to the path T with the layer at the point of penetration is preferably substantially between 3 ° and 15 °, which makes it possible to ensure from the start of penetration an effective thrust on the tissue to form the ripple (in the case of a locking needle, the value of this angle is less essential, since, as will be seen below, the thrust exerted on the tissue by the retainer is extremely effective and sufficient on its own).
  • the progressive retraction movement of the head continues as the stack rises.
  • the point of the needle having entered the tissue moves over the initial portion Ti of the trajectory, then over the cusp portion Tr (FIG. 7c); the fabric repelled during this movement in the direction of the arrow P forms a ripple of increasing height in the perforated part 16 of the head.
  • the means for holding and guiding the needle are adjusted so that the retraction portion Tr of the trajectory is located at a distance from the bearing surface 14a, less than or equal to the thickness of a layer.
  • this adjustment is made so that said cusp portion Tr is located in the lowest layer to be grasped, that is to say at a distance greater than (n - 1) e and less than or equal to ne (where e is the thickness of a layer).
  • the lifting of the stack E continues as does the upward movement of the head (FIG. 7e); the tip of the needle then describes the final portion Tf of the trajectory, which rises relative to the bearing surface and cuts the plane of this surface at the level of the perforated part 16.
  • the needle tip which came out of the fabric on the underside of layer S re-enters it at the level of the ripple.
  • the assembly of the needle tends to fade upward in the groove 15 of the head.
  • FIG. 7f shows diagrammatically the final position of the needle when its tip reaches the end of the portion Tf of the trajectory.
  • the needle tip is positioned recessed in the groove 15 of the head; in the example shown, the needle has come completely back into this groove.
  • the fabric stitched right through, in two places, is perfectly blocked by the needle and the support surface without ability to slide in and out.
  • the proximity sensor 26 controls the pneumatic supply of the jack 12, which blocks the head in the high retracted position.
  • the firmly held fabric is locked in this state and cannot come off regardless of the movements impressed on the head and the stresses exerted on it.
  • the stack E is then brought down and simultaneously the jack 8 is subjected to several pneumatic pulses which subject the plate and therefore the needle / head assembly, rapid movements back and forth in a direction substantially parallel to the plane of the support surface.
  • air is blown in through the channel 4, the orifice 4a of which is in the immediate vicinity of the layer S when the head 14 is fully retracted in the high position.
  • the movements of the actuator 8 and the air blowing are stopped and the gripping device is moved to the desired location.
  • the pneumatic cylinder 12 is then controlled in the opposite direction to condition the descent of the head 14 relative to the plate 6.
  • the needle 23 then undergoes a reverse movement and releases the layer of fabric (FIG. 7g). It should be noted that the presence of the spring 22 allows this movement to be carried out with all the necessary flexibility. At the end of the stroke, the needle returns to its initial position, set back with respect to the bearing surface.
  • FIG. 8 represents a machine for gripping and transferring layers, comprising a device of the type described above, equipped with four gripping assemblies 2.
  • This machine comprises a movable stacking support 28 (or several supports), located below and opposite one of the locations where the gripping device can be positioned.
  • This stacking support is associated with a jack 29 making it possible to raise it towards the gripping device or to lower it again.
  • the gripping device is carried by transfer means adapted to be able to move it between one or more position (s) located opposite the stacking support (s) 28 and one or more other positions located above above places where the layers are to be deposited.
  • transfer means adapted to be able to move it between one or more position (s) located opposite the stacking support (s) 28 and one or more other positions located above above places where the layers are to be deposited.
  • these means are shown diagrammatically by a carriage 30 movable along guide rails 31 and a drive cylinder whose movable rod can be seen at 32, the gripping device is suspended from the carriage 30.
  • control means adapted to generate the course of the following cycle: lifting of the stacking support 28 towards the gripping device until contact with the latter. view of producing the retraction phase of its heads 14, lowering of said support with rapid back-and-forth movements of the plates 6 relative to the chassis 1 and air blowing, transfer of the gripping device to another position, driving the heads 14 to produce the return phase of the needles 23, return of the gripping device to the aforementioned stacking support or another stacking support.
  • each assembly 2 is arranged so that the rods of the jacks 8 have a radial direction (direction extending from the assembly 2 towards the central region of the chassis) and that each needle is located in a tangential plane perpendicular to this direction. It should be noted that such a tangential position of the needles is very favorable for opposing any radial sliding of the fabric during the tensions and relaxations of the latter.
  • the gripping device can be equipped with a needle 33 as shown diagrammatically in FIG. 9.
  • This needle has the same general shape as the needle 23 'but has at its end two separate points 33a and 33b, which the example are formed by beaks with biased upper faces. These points define at their base a front face 33c acting as a retainer.
  • the tips 33a and 33b can have a length of the order of 5/10 mm.
  • FIGS. 10a, 10b and 10c illustrate the gripping of a layer by means of such a needle.
  • the needle first enters the upper layer, in the same way as the needle 23 previously mentioned, and this, until its stop 33c comes into contact with the upper face of the layer (FIG. 10a).
  • the undulation markedly more marked than in the previous case is firmly pinched between the retainer 33c and the opposite edge of the perforated part 16 (FIG. 10c).
  • the gripping of the tissue is therefore carried out not only by pricking the tissue, but also by pinching the ripple: it has proven to be extremely safe experimentally, whatever the thickness of the tissue and its texture.
  • the invention extends of course to the case of a manual device comprising a single head (or possibly a small number of heads) which would be applied manually against a stack in order to separate one or more upper layers.
  • the jack 12 is then replaced by means for guiding the head in translation; the kinematic guide means of the needle remain similar to those described, the blocking of the head in the high retracted position being effected by a latching member, unlockable by hand; a low modulus spring may be provided to ensure the return of the head downwards and the reverse movement of the needle.
  • the maintenance of such a device is carried out by a handle integral with the plate.
  • Such a very simple device facilitates in certain cases (materials having a strong tendency to adhere) the manual operation of gripping and separation of the layers.
