Definitions

  • the present invention relates to a method and a device for molding by scanning ski soles made of thermoplastic material.
  • thermoplastic resins as a coating constituting the sole or sliding surface of skis has led to the development of machines for carrying out repair or renovation operations on these ski soles, in order to restore a surface condition free of roughness or cracks and restore the original mechanical characteristics to these coatings.
  • thermoplastic filler material is continuously fed in a solid form.
  • heating body shaped as a display shoe the filler material being gradually softened in the heating body and conveyed in liquid form under the shoe to be crushed and spread on the ski sole during the sweeping or longitudinal translation movement skating on the ski.
  • the device for implementing this process comprises means for supplying thermoplastic filler material, a heating body with a display shoe shaped to receive the filler material in solid form, for heating and softening it gradually, to bring it in liquid form under a distribution and spreading structure intended to be pressed against the ski sole and to be driven in longitudinal translation on said ski sole in a preferential direction of propagation.
  • the skate has a projection for preheating the ski sole upstream of the distribution structure.
  • the material constituting the ski soles is generally a polyethylene.
  • polyethylene in solid form, strip, wire or granule is generally used as thermoplastic filler material.
  • ski soles in very high molecular weight polyethylene.
  • Such ski soles are obtained by sintering, and formed by slicing.
  • the sliding qualities thus obtained are superior to those produced with polyethylene of lower molecular weight, such as polyethylenes hot molded at a temperature above the softening point.
  • the object of the present invention is in particular to produce a molding of the ski sole by sweeping, making it possible to conserve the sliding qualities of the material constituting the original sole as much as possible, while avoiding recharging the flat parts of the soles with thermoplastic material. ski, and by sufficiently recharging the hollow parts of the soles.
  • the difficulty is in particular to sufficiently recharge the hollow parts of the soles, in order to avoid obtaining hollow parts again after removal of the overmolding material on cooling.
  • the present invention also aims to reduce as much as possible the heating time of the very high molecular weight polyethylene forming the initial sole to be molded.
  • the reduction of the heating time implies an increase in the speed of translation of the overmolding device relative to the ski sole, speed which tends to reduce the time required for overmolding and therefore to increase the production rate.
  • a first attempt may consist in increasing the heating power of the resistors housed in the display pad, in order to increase its temperature and to increase the heating rate of the plastic filler material and of the sole to be molded. It turned out, however, that such an attempt leads to failure, because it makes it possible to slightly increase the scanning speed, but the layer of polyethylene deposited acting as thermal mattress still keeps the heat on the ski sole for too long. . A more appreciable increase in the power and the heating temperature leads to the deterioration of the filler material, and the production of fumes, in particular during the downtimes between two overmolding operations.
  • the aims sought by the invention must not lead to a reduction in the quality of the overmolding obtained, or the distribution of the material deposited on the sole.
  • Another object of the invention is to provide a semi-automatic overmolding device, ensuring by itself the relative transfer of the ski and the overmolding device; according to the invention, it is sought to reduce the size of the device, and in particular to design such a device having a size significantly less than the length of the ski. This requires new means ensuring the maintenance of the ski and its transfer at a regular speed in the device.
  • thermoplastic filler material in a molding head, is successively heated in heating channels, introduced into a transverse distribution groove formed on the underside of the skate structure. display, crushed and spread on the ski sole by a display surface, and, at the end of the display area under the display shoe, the thermoplastic filler material still in viscous form is immediately removed under pressure by a transverse scraper.
  • the process of hunting under pressure should not be confused with a simple scraping.
  • the pressure probably causes a slight expulsion of filler material downstream of the scraper through the recesses of the surface to be overmolded, and the filler material relaxes when it passes from the viscous and compressed state to the solid state. This results in an excess thickness of filler polyethylene in the hollow surface areas requiring repair. This effect would not be obtained with a traditional scraping.
  • the transverse scraper consists of a blade brought substantially to the temperature of the display shoe; the scraper is integral with said display shoe.
  • the blade advantageously consists of a substantially straight transverse lower edge separating an anterior face and a posterior face.
  • the transverse scraper can advantageously be held in sliding contact with the lower edges of the ski, the thermoplastic filler material ensuring sufficient lubrication to promote sliding between the scraper and the ski edges without excessive wear of the scraper and edges.
  • the overmolding head according to the present invention substantially takes up the structure of the devices described in patent FR-A-2 391 054, and further comprises, downstream of the distribution zone, a transverse scraper shaped to scrape the filler material still in liquid form on the ski sole.
  • the transverse scraper is preferably a blade made of heat conducting material and subjected to the action of heating means bringing it to a temperature at least equal to the softening temperature of the filler material.

  • One of the edges of the steel bar forms the sharp lower edge which protrudes below the distribution and display surface of the shoe.
  • the projecting edge of the scraper protrudes below the distribution and spreading surface of the skate at a height of between two and four tenths of a millimeter.
  • the front face of the scraper forms, with the distribution and spreading surface of the shoe, an angle between one hundred and five and one hundred and thirty five degrees, advantageously one hundred and twenty degrees approximately.
  • the overmolding head is mounted oscillating on a transverse axis fixed to a pressing arm connected to the frame, while the ski support is mobile and driven in longitudinal translation.
  • the ski support comprises a movable and removable straddle comprising a rectilinear beam associated with wedges and with means for holding the ski.
  • the external surface of the rectilinear beam forms a bearing surface, opposite to the surface to be machined of the ski, on which rolls a driving roller with transverse rotation shaft urged by a motor and mounted on the frame. Pressing means produce an appropriate pressure to keep the overmolding head in abutment against the ski.
  • the rotation shaft of the roller is advantageously arranged along the mean vertical transverse plane of the overmolding head.
  • the straddle bearing surface includes notches cooperating with corresponding notches formed on the surface of the driving roller.
  • the overmolding head shown diagrammatically in FIGS. 1 and 2, essentially comprises a heating body, generally referenced 1, made of thermally conductive metal, in which are housed heating cartridges such as cartridges 2 and 3 containing a distribution of electrical resistances.

  • Mechanical drive means not shown in the figures, such as knobs driven by a motor and between which the solid filler material engages, force the thermoplastic filler material inside the extrusion pipes 4 and 5 in the direction of the lower end of the extrusion pipes.
  • the extrusion conduits 4 and 5 are each separated into two lower branches 41, 42, 51, 52 respectively, which open, on the lower face 8 of the heating body, in a transverse distribution groove 9
  • the orifices of the four lower branches 41, 42, 51 and 52 occupy positions regularly distributed over the length of the groove and cut said length into four substantially equal sections.

  • the lower face portion 8 opposite the preheating shoe relative to the transverse groove 9 forms the display zone 25.
  • the transverse distribution groove 9 is closed at its two ends, to prevent too rapid creep of filler material at the ends. Its length is between 90 and 100 mm approximately, its width between 4 and 7 mm approximately, its depth between 2 and 3.5 mm approximately. Advantageously, it is possible to choose a length of approximately 95 mm, a width of approximately 6 mm, a depth of approximately 3 mm.
  • the heating body 1, as well as the means for mechanically driving the solid material, are contained in a box not shown in the figures, ensuring protection and thermal insulation of the heating body, only the underside 8 of the body. heater being visible and accessible.
  • a temperature sensor 11 is housed in the heating body 1, and is associated with temperature regulation means for maintain, during operation, the temperature of the heating body 1 at a determined value suitable for melting the thermoplastic filler material in the extrusion conduits 4 and 5.

  • An advantageous arrangement consists of mechanical means allowing the ski to move in the opposite direction illustrated by arrow 130, the overmolding head remaining fixed in the longitudinal position, and being possibly articulated and urged by means of support and support producing the support force F.
  • the upstream zone of the heating body 1 comprising the front zone 10 and the downstream zone of the heating body 1 or display zone 25 are defined. .

  • the bar has a sharp transverse lower edge 16 formed by an anterior face 17 of scraper and a rear face 24 of scraper.
  • the lower edge 16 of the bar forming the scraper 14 is slightly protruding below the lower face 8 of the heating body 1.
  • the protruding value D is advantageously between two and four tenths of a millimeter.
  • the front face 17 of the bar forms, with the lower face 8 of the heating body 1, an angle A of between one hundred and five and one hundred and thirty five degrees and forms with the surface sole to be molded at an angle B between 45 ° and 75 °.
  • Such an inclination produces a wedge effect and a flushing effect which promote the penetration of the thermoplastic material into the slots and other hollow parts of the sole to be molded.
  • An angle B greater than approximately 75 ° produces grazing phenomena.
  • An angle B less than 45 ° reduces the hunting effect too much, and results in a simple crushing effect, the result of which is less favorable. Excellent results have been obtained for an angle B of between 55 ° and 65 °, and therefore for an angle A of between 115 ° and 125 °.
  • the scraper 14 is formed by a removable and interchangeable blade, which can also be adjusted to modify at will the protrusion D of the lower edge 16 below the lower face 8 of the heating body 1. It will however be possible, without departing from the scope of the present invention, to provide a scraper 14 permanently fixed to the heating body 1, without the possibility of adjustment.
  • the operation of the device of the present invention for obtaining a selective overmolding limited to degraded surface areas, is improved by the application of a sufficient force F on the heating body 1 in the direction of the ski sole. , oriented substantially vertically from the display area 25, as shown by arrow 18.

  • the overmolding head is, for this, associated with support means making it possible to support on the one hand the overmolding head and on the other hand the ski to be overmolded.
  • Mechanical means make it possible to drive the overmolding head and the ski 12 in relative longitudinal translation, at a speed V advantageously between 3 and 4 meters per minute, and mechanical means make it possible to maintain the body in support according to the force F determined. heating 1 against the ski sole according to its underside 8, as shown in FIG. 1.
  • the mechanical drive means of the filler material ensure a continuous and regular supply of polyethylene, at a rate sufficient to fill, with a slight excess, the hollow areas of the ski sole 12.
  • force F can be reduced in proportion.
  • Such a device can then more easily be manipulated and actuated by hand, without requiring mechanical means for producing the force F.
  • a driving roller can however assist the operator to produce the regular advance of the device on the sole of ski in the direction of arrow 13.
  • the heating body 1 is kept in abutment on the ski sole 12, applying the necessary force F and said heating body 1 and the ski are driven in relative translation, for example skiing in the direction represented by the arrow 130 relative to a fixed heating body 1.
  • the heating body 1 is maintained at a suitable temperature for melting the thermoplastic material 6, 7 introduced into the extrusion conduits 4 and 5, the filler material being gradually softened in the heating body and conveyed in liquid form under the heating body, and distributed in the transverse distribution groove 9.
  • the flat bottom face 8 of the heating body 1 ensures on the one hand the preheating of the sole part 12 located upstream under the anterior zone 10, then the crushing and spreading of the filler material by the spreading zone 25.
  • thermoplastic filler material still in viscous form, is removed under pressure by the transverse scraper 14.

  • the relative position of the underside 8 of the heating body 1 and the sole 12 of the ski must advantageously be kept constant during the molding operation.
  • the lower face 8 must be slightly detached from the sole to be molded 12 from the ski, so that the only contact with the sole is ensured by the scraper.
