    Description


    [0001] The present invention relates to a glazing panel removal system and method, and particularly to a glazing panel removal system and method that utilises a cutting wire in order to remove the glazing panel by cutting through the bonding material interposed between the vehicle glazing panel frame opening and the glazing panel.

    [0002] Techniques are known utilising a cutting wire to remove a vehicle glazing panel such as a windshield. An exemplary technique is disclosed in GB 2465847, in which a glazing panel removal device is provided with suckers for mounting on the windshield and a pair of spaced winder spools, each for winding in a length of cutting wire. The wire slices through the PU bonding bead positioned between the glazing panel and the vehicle mounting frame. Such techniques are generally extremely effective and efficient in removing glazing panels. WO2011101668A1 relates to a wire reprocessing system.

    [0003] An improved technique and system has now been devised.

    [0004] According to the present invention, there is provided a glazing panel cut out system for use with a cutting wire in cutting out a vehicle glazing panel cut out procedure, the system including:

    a wire dispenser unit for receiving a spool for dispensing cutting wire the dispenser unit having means for mounting the spool enabling cutting wire to be paid out from the spool; and;

    a winder unit including;

    at least one spool for winding cutting wire dispensed from the dispenser, the winder unit having means for mounting the spool enabling cutting wire to be wound on to the spool during the cut out procedure;

    wherein the spool is configured to be interchangeably be mounted on both the dispenser unit and the winder unit.



    [0005] It is preferred that the winder unit and the dispenser unit include a mounting arranged to mount the spool rotatably on the respective winder or dispenser unit. This can be a commonly configured mounting arranged to mount the spool rotatably on both the respective winder or dispenser unit. A common mounting system for both the dispenser unit and the winder unit simplifies the system design.

    [0006] Viewed in an alternative aspect, the invention provides a method of removing a glazing panel from a frame in a vehicle using a cutting wire, wherein the cutting wire is wound on a spool of a winder unit during a cut out procedure and the spool is subsequently removed from the winder unit and used to dispense the cutting (already wound on the spool) wire at a subsequent time in further cut out procedure. This enables the cutting wire to be re-used.

    [0007] According to the invention, therefore, the spool is preferably mounted rotatably on the winder unit during the cutting procedure and subsequently removed and (at a later time) mounted on a dispenser unit to dispense the already used cutting wire during a further cut out procedure.

    [0008] It is preferred that the winder unit and/or the dispenser unit further comprises a mounting arrangement for mounting the winder unit on the glazing panel;

    [0009] In a preferred embodiment, the winder unit includes at least one wire wrap around guide element (such as a rotatable pulley) preferably spaced from the winder spool and/or the mounting means.

    [0010] In one embodiment, the winder unit includes first and second spools for winding the cutting wire wherein each of the first and second spools can interchangeably be mounted on both the dispenser unit and the winder unit.

    [0011] Typically, in use, the dispenser unit and the winder unit are mounted to opposed faces of the glazing panel.

    [0012] In a preferred embodiment, the mounting means for the dispenser unit and/or the winder unit comprises a suction mount.

    [0013] A brake or drag arrangement may beneficially be provided to brake or hinder the paying out of the wire from the dispenser unit.

    [0014] In one preferred realisation of the invention, on the winder unit two winder spools are arranged in side by side arrangement an a respective wire guide wheel or pulley is positioned outwardly of each respective winder spools.

    [0015] In a preferred embodiment the winder unit spool or spools mounting includes a ratchet arrangement enabling spool rotation in one or other direction to be inhibited.

    [0016] According to an example, not forming part of the invention, there is a spool containing a length of already used cutting wire, the spool having a mounting arrangement for interchangeably mounting the spool on a mounting portion of a wire dispenser unit for use in a cut out procedure or on a mounting means of a winder unit.

    [0017] The invention will now be further described in a specific embodiment by way of example only and with reference to the accompanying drawings, in which;

    Figure 1 is a schematic plan view of a winder unit of an exemplary cut out system in accordance with the invention;

    Figure 2 is a schematic representation of the arrangement in an exemplary mode of use;

    Figure 3 is a schematic representation showing the interchange-ability of the wire spools in accordance with the invention;



    [0018] Referring to the drawings, and initially to figures 1 to 4, there is shown a cut out system particularly for use in cut out of bonded vehicle glazing panels such as windscreens. The cut out system comprises a winder unit 1 and a wire dispenser unit 2.

    [0019] The winder unit 1 comprises a pair of releasable suction cup mounts 10, 11 enabling the winder unit to be releasably secured to the windscreen. The suction cup mounts comprise a rigid plastics cup 12 and underlying flexible rubber skirt membrane 13. Respective actuation/release levers 14 enable consistent suction to be applied and released. Such suction mounts are commonly employed in windscreen replacement and repair technology. The suction cup mounts 10, 11 are pivotably/tiltably mounted to the support bracket 15 of the winder unit to ensure that both mounts 10, 11 can locate in good engagement with the windscreen despite the curvature of the windscreen.

    [0020] The main body of the support bracket 15 carries a pair of axial winding drive bosses 18 which are supported in bearings 16, 17 provided on the winder unit. A wire wind on spool 4 is provided with a mounting ability to be mounted removably under-slung onto either of the respective drive bosses 18. The drive bosses 18 are driven axially rotationally either manually via a hand winder or by means of a mechanical actuator such as a motorised winding or winching tool. In figure 1, the wire wind on spool 4 is shown on under slung on to the left hand drive boss 18, but is capable of being removed from the left hand drive boss and mounted for rotation on the right hand drive boss. Drive bosses 18 are provided with female sockets 19 (square bores) for receiving the male driving tool.

    [0021] Positioned outwardly of the winding spools are respective wire guide pulley wheels 8, 9 of low friction plastics material. The pulley wheels are mounted to be rotatable about respective rotational axes. The guide pulleys rotate as the cutting wire is drawn tangentially across the pulleys as will be described. The winder spools 4, 5 are held to rotate in one direction only (each in opposite senses) by respective ratchet mechanisms. Each mechanism includes ratchet override permitting prior tightened wire to be slackened, or unwound (reverse wound).

    [0022] In common with the technique disclosed in GB 2465847, and as shown in figure 2, the winder unit 1 is secured internally of the vehicle to the surface of the glazing panel 3 above the steering wheel. A wire dispenser device or unit 2 is secured to the exterior surface of the glazing panel 3. The dispenser device 2 includes a sucker mount 2a and a mounting 2b that is configured to receive the spool 4 in such a manner that the spool 4 can be rotated to pay out cutting wire from the spool 4 when it is operably mounted with the dispenser device 2.

    [0023] It will be appreciated that the key to the invention is that the winder unit 1 and the dispenser device 2 should have means (winder unit bosses 18, and dispenser mounting 2b) for commonly mounting the spool 4, permitting the spool 4 to be interchangeably mounted on both the winder unit 1 and the dispenser device 2. The means by which common mounting may be achieved will be various and readily realisable by the skilled addressee.

    [0024] The invention enables wire (fresh or used) to be paid out from the spool 4 on the dispenser device 2, and subsequently collected on an identical spool 4 mounted on the winder unit 1. Subsequently the collected wire on a spool 4 on a winder unit 4 can be removed, and the spool fitted for dispensing duty on a dispenser device 2.

    [0025] In use the operation is generally similar to the operational sequence described in GB 2465847. Prior to cutting, the wire 41 is wrapped around the external peripheral edge of the glazing panel as disclosed in GB 2465847. The dispenser spool 4 which is free to rotate as to pay out wire from the dispenser spool as tension of a required magnitude is put upon the wire. An adhesive tape patch may be used to give resistance to paying out of the wire from the spool. Other brake devices (typically resistance or friction providing devices may be used in addition to or as an alternative to the adhesive patch).

    [0026] During cutting, if excessive resistance occurs, from tough or large PU adhesive beads, the wire is able to spool off the dispenser device 2 and slip and slice past the PU adhesive. The winder unit is moved during the cutting procedure across the windscreen to the other side and re-secured to the windscreen. Prior to repositioning the unit 1, the ratchet of the winder boss 19 carrying winder spool 4 is released to permit the wire to be wound out from the spool 4 as it is moved across the glazing panel to be repositioned. The ratchet is subsequently re-engaged and spool 4 once again operated to wind in the wire.

    [0027] The present invention provides the benefits of wire cutting systems but has the significant benefit of enabling the cutting wire to be re used as a result of making the spool interchangeably mountable on the dispenser unit 2 and the winder unit 1. This avoids the necessity of unspooling the wire from the winder unit following collection on the winder unit.
