    Description


    [0001] The present invention relates to apparatus and a method for shaping wire, and is concerned particularly, though not exclusively, with apparatus and a method of forming springs for resilient articles such as mattresses, seats and the like.

    [0002] A previously considered spring coiling machine is depicted schematically in Figure 1, in which the apparatus 100 typically comprises a wire supply portion 102, for supplying wire W, from a reel (not shown), in the direction of arrow A1, having a pair of guide rollers 104 and a pair of driven feed rollers 106, and a spring forming station 108, comprising forming tools 110, a pitch control tool 112 and a cutter 114, for shaping the spring S and then cutting the formed spring from the supply of wire. These elements are usually mounted on a heavy support plate 116. The apparatus shown is simplified, and some parts have been omitted from the drawing in the interests of clarity.

    [0003] When the newly formed springs S have been cut from the supply of wire, they are often transported immediately to an article into which they are to be incorporated, or to which they are to be attached. Various types of transportation apparatus T are used to transport the springs, including single belts, pairs of belts and magnetic conveyors, in the direction of arrow A2 in this example.

    [0004] Transporting springs, especially small ones, can be troublesome, due to their resilient nature and low mass.

    [0005] The mode of transportation must be selected and carefully optimised for the springs being transported, in order to minimise the incidence of mishandling, which may lead to downtime in the process of manufacturing the articles incorporating the springs.

    [0006] Because of this, whenever the type of spring is changed in the process, for example when springs of different shapes, lengths and/or of different wire gauges are to be used, the transportation arrangements must often be changed to re-optimise the process. This can also be time consuming.

    [0007] DE102013206655 describes a method and a system for producing coil springs of wire, in which wire is fed from a wire supply to a numerically controlled spring manufacturing machine, portions of the wire are successively formed into coil springs in the spring manufacturing machine in a forming operation, each coil spring is separated from the supplied wire after the forming operation, and separated coil springs are then transported to at least one downstream processing station. For transporting coil springs at least one spring magazine is used, which has plurality of prepared receiving spaces for each coil spring at defined positions of the spring transport magazine, wherein a plurality of successively provided separated coil springs distributed in a placement operation on different receiving locations and after completion of a placement operation as a spatially ordered group means the spring transport magazine are transported orderly.

    [0008] The present invention is defined in the attached independent claims, to which reference should now be made.

    [0009] Further, preferred features may be found in the sub-claims appended thereto.

    [0010] According to one aspect of the present invention, there is provided wire shaping apparatus, the apparatus comprising a forming device and a supply station for supplying a length of wire to the forming device, the forming device including one or more tools for shaping a portion of the wire and cutting it from the length of wire, and wherein the forming device is arranged for movement independently of the supply station to place the shaped and cut wire portion in a desired position.

    [0024] The heating tool may be arranged in use to heat the wire by passing an electric current through the wire.

    [0025] A single control apparatus may control one or more tools of a plurality of forming devices. A single supply station may be arranged in use to supply a plurality of forming devices.

    [0026] The wire conduit may comprise a sheath or sleeve, preferably of plastics material.

    [0027] In a preferred arrangement the forming device is moveable in two, more preferably three, dimensions. The forming device may be mounted for movement on a moveable arm or platform, or on a robotic arm or similar. Alternatively, or in addition, the forming device may be configured for hand operation, for example such that it can be manipulated by an operative to position the forming device relative to a work piece or desired location for the formed wire portion. The wire may comprise metallic wire.

    [0028] The invention also includes a method of shaping a wire, the method comprising supplying a length of wire from a supply station to a forming device, shaping a portion of wire and cutting it from a remaining length of wire using one or more tools at the forming device, and moving the forming device independently of the supply station to place the shaped and cut wire portion in a desired position.

    [0029] The method may comprise moving the forming device and feed apparatus, for example together, independently of the supply station. Alternatively, the method may comprise moving the forming device independently of the supply station and feed apparatus, one or both of which may be stationary.

    [0030] The invention also includes a method of shaping a wire, the method comprising supplying a length of wire from a supply station to a forming device, shaping a portion of wire and cutting it from the remaining length of wire using one or more tools at the forming device, and positioning the shaped and cut portion of wire in relation to a work piece, wherein the method comprises moving the forming device independently of the work piece to place the shaped and cut wire portion in a desired position in relation to the workpiece.

    [0033] In a further aspect, the invention provides a computer readable medium, comprising instructions that, when executed by a computer of a control apparatus of a wire shaping apparatus according to Claim 1, cause the computer to perform the method of shaping wire in accordance with any of Claims 13-17.

    [0034] The invention also comprises a computer program comprising instructions which, when executed by a computer of a wire shaping apparatus according to Claim 1, cause the computer to perform the method of shaping wire in accordance with any of Claims 13-17.

    [0035] A preferred embodiment of the present invention will now be described. By way of example only, with reference to the accompanying diagrammatic drawings, in which:

    Figure 1 shows a previously considered spring forming apparatus; and

    Figure 2 shows a wire shaping apparatus according to an embodiment of the present invention.



    [0036] Turning to Figure 2, this shows schematically apparatus for forming wire components, which are in this example springs, generally at 200. A supply station 202, for supplying spring forming material, such as metallic wire W, includes a pair of guide rollers 204 and pair of driven feed rollers 206, mounted on a heavy support plate 216. The wire is fed through a flexible sheath FS to a remotely located wire shaping device, in particular a spring forming device 208, comprising forming tools 210, a pitch control tool 212 and a cutter 214. The forming tools 210 and the pitch control tool 212 form the wire into a spring S, which is cut from the supply of wire when it is complete.

    [0037] A wire payoff (not shown) such as a reel, spool or preferably a drum, supplies the rollers.

    [0038] The tools 210, 212 and cutter 214 are controlled remotely from a control station 220 via a bundle of flexible control cables 222, which may include a power cable (not shown). The spring forming device 208 is mounted on a positioning member 224, such as a robot arm or moveable table, configured for three-dimensional movement, and/or optionally adjustments in inclination.

    [0039] Without the heavy plate 216 and rollers 205, 206, the spring forming device 208 is sufficiently light in weight and compact as to be moved by the positioning member 224 to a location in which springs are to be used. This avoids the need for transportation apparatus to convey the springs from the place where they are formed to the place where they are to be used. When springs of a different size or shape, or of a different wire gauge are to be used, they are formed and placed where they are needed, without the need to re-optimise a transportation apparatus.

    [0040] In another embodiment (not shown) the forming device and light weight rollers are mounted for common movement in relation to the wire payoff, such as a wire supply in the form of a drum of coiled wire.

    [0041] The control cables could comprise flexible rods or linkages, or the control could be provided wirelessly, or via electric cables. Similarly, the cutting tool 214 is shown as a mechanical device, but could, as an alternative (not shown) comprise an electric arc cutter, or similar.

    [0042] The springs could be heated locally at the spring forming device, so as to treat them, and also if desired to weld or otherwise attach them to an article, such as to a metal plate or clip, or other fixture.

    [0043] The forming device is also moveable with respect to a work piece, in one, two or preferably three dimensions, and optionally in inclination, with respect to a work piece.

    [0044] This versatility of the wire shaping apparatus according to embodiments of the present invention allows the forming and precise placement of wire components, such as springs of different types, where they are needed, either in or on another work piece/article or in an aperture or magazine, or onto a magnetic belt, without the need for separate transportation apparatus for different types of wire components.

    [0045] There are many examples of articles to which the apparatus and methods described above can precisely deliver shaped components. Such examples include, but are not limited to: automotive articles such as engines, suspensions and seating, other vehicles, plant and machinery and furniture.

    [0046] Whereas the above-described example is of forming springs, it will be understood that the apparatus and methods described herein could also be used to shape a portion of wire into a configuration other than a spring.

    [0047] Also, the term "wire" as used herein is intended to cover or include any filament, thread, tube or similar, whether solid or hollow, and whether metallic or not, which is capable of being shaped in the manner described above.

    [0048] Similarly, it will be understood by the skilled person that a single control apparatus may be used to control one, or more than one, of the tools of a plurality of forming devices. Thus, a relatively expensive control apparatus can be used with a plurality of less expensive wire shaping heads.

    [0049] The remote control of the one or more tools can be by mechanical, electrical or electronic means and may use cables and/or wires or wireless signal paths, or a combination of these.

    [0050] As stated above, the forming device and a relatively light weight feed apparatus may be arranged to move, for example together, independently of the supply station by mounting them on a moveable positioning member such as 224. Alternatively, the forming device may be arranged to move independently of the supply station and feed apparatus, one or both of which may be stationary.

    [0051] In another embodiment (not shown) the apparatus has one or more ancillary tools. The one or more ancillary tools may be arranged in use to move with the forming device, and are preferably arranged as part of the forming device. The one or more ancillary tools may include one or more of the following, but not limited to: a cutter, router, drill, cropper, trimmer, laser, and may be used, for example, to perform tasks, such as preparatory tasks or finishing tasks in respect of a work piece, in relation to which a shaped portion of wire is to be positioned. In one such example, a work piece may comprise a portion of foam into which formed springs are to be deposited. An ancillary tool, such as a router, may be used to create an aperture or recess for receiving a spring. Another ancillary tool, such as a cutter/trimmer/cropper tool, may be used to crop or trip the work piece.
