Definitions

  • the invention relates to an improvement in the preparation of ready-to-use doses, of animal semen intended for insemination, artificial, and more precisely a machine according to the preamble of claim 1 intended for the manufacture of such doses as well as doses according to the preamble of claim 6 produced by this improved machine.
  • a machine and such doses are described in FR-A-2,667,843 and EP-A-480,798 respectively.
  • Doses produced in strips are known in particular comprising sachets made from two sheets of flexible thermoplastic material fixed to each other by weld beads each delimiting a pocket in an approximately rectangular path, one of the short sides of which is interrupted, the weld bead determining towards the outside of the pocket starting from the interruption on this small side, a filling duct extended by a centering flare widening in the direction opposite to the bottom of the rectangular pocket; the two sheets of thermoplastic material are pierced, on the outside of each trace formed by the weld bead, with holes for the tape drive fingers along the manufacturing machine, and in particular in the filling station for the pockets; these holes are themselves surrounded by a weld bead of the two sheets, locally increasing the rigidity of the strip and reducing the tendency for the latter to deform in this zone during filling.
  • the bags are filled with seed sequentially in conjunction with a stepwise movement of the strip in the filling station, by means of a tubular needle connected to a seed reserve, successively introduced into the bags during a phase immobility of the sachets in this station; for this purpose, the needle is driven in a longitudinal translational movement bringing its free end into the filling duct, then remains stationary for the time of filling, and then is driven in a longitudinal translational movement in the opposite direction to the previous one to remove it from the conduit; in the next station, the machine for manufacturing the doses welds together the two sheets of thermoplastic material so as to connect the opposite walls of the centering flare, and thus constitutes a weld bead closing the line of the pocket and thus sealing of the pocket.
  • the sachets are then separated from each other by extending the separation incisions in order to form ready-to-use doses.
  • the probe can be adapted to the dose in a very short time which considerably limits the risks of contamination of the semen by germs. contained in ambient air, and insemination can start immediately after; the actual insemination is also simple and rapid, and, the dose being maintained higher than the tip of the probe, emptying is natural by the combined action of atmospheric pressure, of the animal's genital tract, and of the intrinsic shape of the pocket, flat without reserved volume and without the need to replace a volume of seed with the same volume of air as the flow proceeds.
  • the object of the invention is to remedy this drawback and consequently to create a ready-to-use dose of animal semen which avoids the use of a tool for opening it.
  • the problems posed to create such a dose being more difficult to solve than suggests a superficial examination, the invention relates more particularly to the improvements made to a machine for manufacturing semen doses, and the doses produced by means of this machine. .
  • the invention therefore consists of a machine for manufacturing ready-to-use doses of animal semen, supplied with empty sachets each comprising a filling duct extended upwards by a flaring, machine of the type comprising a filling station equipped with '' a tubular needle connected to a seed reserve and which is driven in a longitudinal translational movement bringing its free end into the filling duct, then immobilized for filling with seed, and driven in a longitudinal translational movement in the opposite direction to the previous one to remove it from the conduit, machine characterized in that the free end of the tubular needle is the free end of a nozzle mounted to slide inside a cleanliness ring, so that when raising the nozzle after filling the bag, after the free end of the latter has reached that of the ring, no seed residue remains externally to the nozzle to soil the following sachet before welding, and in that it has inverted U-shaped welding members to seal the dose by creating a weld bead of the same shape extending up the contour of the flare ,
  • the internal faces of the sachet are kept dry above the level of the flow conduit and the weld produced is in an inverted U, at the time of the manual opening of the dose, the tearing of the two sheets constituting the sachet is most likely to occur in two different directions always transverse to the flare.
  • the invention also relates to a dose of animal semen produced by such a machine, of the type in which the semen is contained in a sachet consisting of two sheets of thermoplastic material welded by a weld bead delimiting a pocket to which is connected a conduit for filling extended by a flaring, dose of seed characterized in that it comprises a sealing weld bead in the form of an inverted U whose branches join the part of the weld bead delimiting the widening in its widest part, an incision approximately perpendicular to the branches of inverted U, and dry internal walls at least between these branches of inverted U.
  • the opening of this dose therefore does not require any instrument, and is faster than the opening of known doses; moreover, this property is obtained without creating in the sachet a zone of fragility so great that it notably increases the risks of involuntary opening of the dose.
  • the problem of allowing a simple opening of a sachet without the aid of a more or less contaminated instrument is generally solved by creating either a line of perforations extending between the two areas to be separated, or a tear primer from an edge of the bag, for example in the form of a slit extending in the direction in which the tearing is desired, or a V incision whose tip is directed in this direction.
  • the two thermoplastic sheets 1 are pierced with four circular holes 7 on the outside of the approximately rectangular layout of the weld; two of these holes are above the short side of the rectangle interrupted by the filling duct, on either side of the centering flare, and the other two below the short side constituting the bottom of the pocket , with the same spacing (of the order of four to five centimeters); these holes 7 are each surrounded by a weld bead.
  • An incision 8 extends perpendicular to the large median of the rectangle, above the upper level of the flare 5; in this way, a tear in this direction perpendicular to the large median reaches the weld bead fixing the sheets 1 to each other, in the region of the sealing bead 6 and not in that of the centering flare 5 , which avoids too extensive damage to the latter; in order to benefit from a good "grip" facilitating the guidance of the tear in the right direction, it is better to start by tearing the bag towards the nearest edge; the length of the incision 8 is of the order of two centimeters, so that this first phase of tearing of the sheets of thermoplastic material can be accomplished by the user simply by inserting one of his fingers into the incision and pulling on the wall thereof; an incision that is too short to allow the user's finger to be inserted would make tearing difficult due to the relatively high mechanical resistance of the thermoplastic material, the choice of which is motivated by the robustness as well as by the seal against external aggressions ( humidity, gas, virus)
  • the sealing weld bead 6 is produced as in FIG. 1 in the form of an inverted U, the free ends of the parallel branches of which are in continuous connection with the ends of the weld bead determining the flaring 5 who are the most excluded.
  • the tendency to tear in two different directions can be further increased by making the bags using two sheets of slightly different thicknesses, or even by orienting the slit in a direction slightly inclined relative to the perpendicular to the branches of the U, but at an angle of less than ten degrees, otherwise we would find the drawbacks associated with a returned V-shaped weld bead.
  • the incision device shown in FIG. 2 comprises an interchangeable blade 11 in the shape of a rectangular trapezoid, the cutting edge of which is the side inclined with respect to the bases and of which an opposite part is placed at the bottom of a housing extending over the entire length of a support plate 12 of generally parallelepiped shape; this housing has a width barely greater than that of the blade, but a substantially greater depth; a counterplate 13 also of generally parallelepipedal shape is itself disposed in the housing over the blade so that the latter is pinched between the plate 12 and the counter plate 13.
  • the blade is fixed by means of screw 14 whose head is supported on or in a housing of the counterplate, and the rod passes through slots provided in the blade in a known manner (it can be for example a blade conventional adaptable to knives known in the art as Stanley knives), and is screwed into tapped holes in the plate.
  • This blade support is mounted on the manufacturing machine, by means of an axis 15 (in one or two parts) passing through it, carried in a bearing of a base 16, so that the blade 11 is movable with its support and its base 16 in a plane approximately perpendicular to the longitudinal axis of the dose and intersecting the plane of the sachet above the widest part of the flare 5; its inclination of a few degrees maximum is preferably modifiable by pivoting the base 16.
  • the heating jaws can be of a thermoregulated type coming into pressure on the film, known per se, insofar as they are adapted to produce an inverted U weld bead; for this purpose their facing zones intended to come to press the thermoplastic sheets have themselves an inverted U shape.
  • the filling cleanliness device shown in FIG. 3 and fitted to the filling station comprises a tubular needle 21 connected to a seed reserve (not shown), having a nozzle 22 a few centimeters long adapted to penetrate the filling duct 4 of the dose, and a portion 23 of seed delivery of larger diameter connected to the nozzle by a shoulder or preferably a frustoconical reduction 24.
  • the tubular needle 21 is carried by the manufacturing machine via '' a shouldered needle holder 25 having a portion 26 of large diameter pierced with a diametral hole through which the portion 23 of seed feed, this feed portion 23 being fixed thereto by means of a screw 27 extending axially in this part of large diameter, and a part 28 of smaller diameter fixed in the machine and having a lateral groove (not visible in the figure) extending in the same direction as the longitudinal axis of the needle.
  • the cleaning device is a removable and disposable ring 29 made of synthetic material, for example that known commercially under the name DELRIN, held on a support (not shown) consisting of two cheeks arranged face to face and between which a corridor is determined.
  • this ring 29 comprises, on the side of the free end of the nozzle, a region 30 of smaller diameter adapted to be inserted between the two sheets of thermoplastic material, and, on the opposite, a fixing flange 31 by which it is kept in its support; the hole in the ring 29 has, at the top of the collar, a small support chamfer which can serve as a stop for the frustoconical reduction 24 of the needle 21.
  • the tubular needle 21 For filling the sachet, the tubular needle 21 is lowered along of its longitudinal axis and introduced between the two sheets 1 in the flare 5 then in the conduit 4, and the descent continues until its frustoconical reduction 24 abuts against the chamfer of the flange 31 of the ring 29, of which the region 30 of smaller diameter is inserted between the two sheets; then the filling is carried out; when the level of seed reaches the desired level, the tubular needle 21 is actuated in longitudinal translation upward, with, almost invariably at least one drop of seed at the free end of its nozzle 22 and around it; when the free end of the nozzle 22 reaches that of the ring 29, either the residual seed drop is detached from the nozzle 22 by the free end of the region 30 of small diameter of the ring, or the continued translation of the nozzle upwards retracts the drop inside the ring; if the quantity of residual seed is relatively large, a part is detached and falls back into the pocket and / or is deposited in the filling duct, and
  • the operations can be continued (inverted U-seal and incision of the bag which has just been filled) and another bag can be filled, the needle filling being lowered through the ring without its outer wall being soiled by semen, and thus the faces of the sheets constituting the sachet remain free from any staining of semen.
  • the removable and disposable cleanliness ring makes it possible to dry the two walls of the sheets constituting the sachet and ensures perfect welding of the U produced, during filling.
  • the two branches of the U being perfectly welded, the self-detaching is carried out in ideal conditions and the rupture of the first sheet is always lower than that of the sheet below, while if we welded on humidified sheets , these two sheets would tear in parallel and the introduction of the insemination probe would become problematic from now on.
