Definitions

  • the invention relates to a device for repairing the tread covering of a ski with a sliding in the ski longitudinal direction relative to the tread sliding shoe comprising a means for melting a shoe material supplied to the thermoplastic lining material and distributed over the application width, opening in the region of a distributor surface distribution channels for the melt , wherein the distributor surface is delimited by a scraper downstream of the distributor channels in the direction of displacement.
  • the covering material supplied in wire form to the sliding shoe is melted by means of a heating device surrounding the wire guide and the melt is fed to the running surface via distribution channels adjoining the wire guide, in the region of a distributor surface opposite the running surface , between which and the running surface results in a thin gap filled with melt, which is delimited by a scraper following in the direction of displacement of the sliding block the distribution channels.
  • a disadvantage of this known device is especially that for melting the lining material a comparatively high heating power is required so that a sufficient supply of melt can be ensured even at higher feed speeds of the shoe.
  • high heating capacities bring the risk of overheating of the lining material used with it.
  • the discharge amount of the melt can not be adjusted depending on the respective ski width to the respective requirements.
  • monoskiers such as snowboards, can have a width that exceeds twice the width of a conventional alpine ski.
  • the invention is therefore based on the object, a device for repairing the tread covering a ski of the type described in such a way that the associated with overheating of the lining material disadvantages can be avoided without having to provide an elaborate scheme for this.
  • the invention achieves the stated object in that the distribution channels emanate from at least one melt chamber and discharge valve, which can be actuated by applying pressure on the tread of the ski plunger, and that the melt chamber to one with the device provided for melting the lining material guide provided for the lining material.
  • the outflow valves in the distribution channels emanating from such a melt chamber provide for a discharge amount of the melt adapted to the respective width of the ski to be treated, because only those distribution channels are opened whose outflow valves are actuated via the pressure rams provided for this purpose, when the over the distributor surface of the shoe protruding plunger when placed on the running surface of the ski during the relative displacement of the shoe against the ski against the force of a closing spring of the respective spill valve are moved and the valve is opened according to this travel.
  • the means for melting the lining material guide for the lining material ensures even at a relatively low receiving volume of the melt chamber independent of the discharge temperature for the outflowing melt, especially if the shoe has an additional heater for the melt chamber.
  • the device for melting the lining material in the opening into the melt chamber guide may consist of a preferably electric heater. Particularly advantageous conditions arise, however, when the device for melting the lining material in the guide comprises a screw extruder, which may optionally be additionally heated.
  • melt chamber For the provision of a melt chamber, various constructional measures can be taken in the shoe.
  • a preferred construction is obtained in that the melt chamber consists of a hole in the sliding shoe which runs in the direction of the application width and is closed at both ends, from which the distribution channels emerge as radial stub lines.
  • Such a melt chamber formed by a bore not only brings favorable manufacturing conditions with it, but also allows a parallel arrangement of the distribution channels with an at least approximately perpendicular to the distribution surface axis and thus a corresponding direction of movement of the plunger for actuating the discharge valves, which can be ranked comparatively close together to allow a sufficiently sensitive adaptation to the respective ski width.
  • one melt chamber can be charged with the one and the other melt chamber with the other lining material, these different lining materials being applied to the running surface of a ski via separate distributor surfaces.
  • the distributor surfaces are inclined relative to each other at an obtuse angle, so that it is necessary to use one of these distributor surfaces of a pivoting of the shoe, namely the supplement angle to the mutual inclination angle. Because of the distribution channels secured by discharge valves, there can be no unintentional loss of melt in the area of the freed distribution area. Be the two distribution areas At their ends facing each other delimited by the scrapers, so opposite directions of the shoe against the ski are required for the use of the two distribution surfaces. This can be used to edit skis one after the other in the opposite direction, which makes it unnecessary to return the shoe to a predetermined starting position by means of an idle stroke.
  • a frame 2 with a clamping device 3 for the ski 1, the end supports 4 and between these end supports 4 center pads 5 comprises. While the end support for the ski tip is fixedly mounted in the frame 2, the end support 4 for the ski end and the middle supports 5 can be adjusted in the ski longitudinal direction to allow adaptation to different ski lengths.
  • the intended for the repair work of the tread lining shoe 6 is arranged in a along a guide 7 of the frame 2 movable carriage 8, the feed drive designated 9.
  • the shoe 6 is mounted in the carriage 8 via a pivot lever 10 of height adjustable, which is hinged to a pivot cylinder 11.
  • two supply spools 12 and 13 for a plastic wire are provided on the carriage 8, which is fed to the sliding shoe 6 with the aid of a feed device, which is not known for reasons of clarity.
  • the guide 14 connected to the sliding shoe 6 for the wire-shaped covering material is enclosed by a device 15 designed as an electric heater for melting the covering material.
  • the guides 14 open for the lining material not in distribution channels, but in a melt chamber 16, which is preferably formed as over the application width of the shoe 6 extending bore 17 which is closed by plugs 18 end.
  • the proposed distribution channels 19 are formed as parallel, radially extending to the bore 17 branch channels, which are completed by means of discharge valves 20.
  • These outflow valves 20 have a valve body 22 which is loaded by a closing spring 21 and which forms a pressure plunger 25 projecting over a distributor surface 23 or 24 of the sliding shoe 6.
  • the plunger 25 and the valve body 22 can also be summarized in the form of a ball valve.
  • the sliding block 6 has two separate melt chambers 16 which have separate guides 14 for the unwound from the supply reels 12 and 13, wire-shaped covering material. These melt chambers 16 are associated with separate distribution surfaces 23 and 24 which are inclined at an obtuse angle to each other. By pivoting the sliding shoe 6 by the supplement angle to this angle of inclination between the distributor surfaces 23 and 24, one of the distributor surfaces can optionally be used.
  • the two distributor surfaces 23 and 24 associated scraper 27 are provided at the mutually facing ends of the distributor surfaces 23 and 24, so that the working direction for the two distributor surfaces 23 and 24 runs in opposite directions.
  • the sliding shoe 6 in the indicated feed direction 28 can apply coating material over the distributor surface 23 and in the opposite direction of displacement of the carriage 8 via the distributor surface 24, which makes a return stroke for returning the carriage 8 to a starting position superfluous.
  • the pivoting of the shoe 6 by the supplement angle to the mutual inclination angle of the distributor surfaces 23 and 24 can by a pivot cylinder 29th be performed, which is provided in the carriage 8.
  • an additional pivoting cylinder 30 it is also possible to adjust the inclination of the shoe 6 in the respective working position relative to the ski 1 in order to take into account, for example, the blade curvature of the ski 1.
  • the possibility of bringing spatially separated distribution areas 23 and 24 into use permits the optional use of different covering materials, so that the supply reel 12 can be provided, for example, with a dark wire-like covering material and the supply reel 13 with a transparent covering material. But it is also possible to use the same covering materials for both distribution surfaces 23 and 24, if only one idle stroke of the carriage 8 should be avoided.
  • a heater 31 for example in the form of a heating element, are provided is arranged in the shoe 6 between the distribution channels 19 and thus also ensures a corresponding heating of the melt in the region of the distribution channels 19.
  • Fig. 2 can be removed, brings the arrangement of the wiper 27 in the region of the mutually facing ends of the distributor surfaces 23 and 24 with the possibility to form the wiper 27 for both distributor surfaces 23, 24 by a common wiper strip 32. Due to the necessary pivoting of the sliding block 6 between the two working positions for the distributor surfaces 23 and 24 results in the two working positions a comparable support of the shoe 6 on the one hand on the outflow valves 20 downstream in the feed direction scraper 27 and on the other hand via the outflow valves 20 upstream rollers 26th To the gap between the used distributor surface 23, 24 and To adapt the tread of the ski 1 to different conditions, the rollers 26 can be mounted on an eccentric shaft, so that by rotation of the eccentric shaft, the axis of rotation of the roller 26 is displaced accordingly.
  • the carriage In order to detect the shift position of the carriage 8 relative to the ski 1 and to be able to use the control, the carriage can be assigned a corresponding sensor 33, via which, for example, the ski end can be indicated or a path-dependent control intervention can be initiated.
  • the device 15 is designed to melt the lining material in the form of screw extruders 34 whose housings are part of the guide 14, through which the lining material arrives at the melt chambers 16.
  • screw extruders 34 have the advantage that the melting of the lining material can be carried out largely independently of the conveying speed of the lining material under constant temperature conditions.
