Definitions

  • This invention is concerned with apparatus for performing combined marginal roughing and toe scouring operations on shoe bottoms, comprising a shoe support and roughing tool supporting means, between which relative movement, lengthwise, widthwise and heightwise of the bottom of a shoe supported by the shoe support, can take place whereby a roughing tool supported by the roughing tool supporting means is caused to operate progressively along marginal portions of the shoe bottom, the apparatus also comprising toe scouring tool supporting means, between which and the shoe support relative lengthwise and heightwise movement can be effected thus to cause a toe end portion of the bottom of a shoe supported by the shoe support to be scoured.
  • the scouring tool thus applies a pressure to the shoe bottom commensurate with the weight of its mounting, and that the heightwise position of the tool is determined according to the shoe bottom contour. It will be appreciated, however, that if the applied pressure is sufficient to remove pleats from a shoe made of a relatively heavy material, then it is likely that, with a shoe of lighter material, the applied pressure will be excessive leading to damage to such shoe. On the other hand, if the pressure is sufficient only for a shoe of lighter material, then it will be inadequate for a shoe of heavier material.
  • first, second and third numerically controlled motors by which relative movement, lengthwise, widthwise and heightwise of the shoe bottom, is effected between the shoe support and the roughing tool supporting means, and of a further numerically controlled motor for effecting relative heightwise movement between the shoe support and the scouring tool supporting means
  • computer control means is provided by which drive signals are generated and supplied to said, first, second and third numerically controlled motors in accordance with a programmed instruction including digitised co-ordinate axis values, using three co-ordinate axes, for a plurality of successive selected points along the marginal portions of the bottom of the or a similar shoe, and further by which drive signals are generated and supplied to said further numerically controlled motor, such signals being derived from the digitised co-ordinate axis values forming part of the programmed instruction by which the marginal roughing operation is controlled, whereby to determine the path of the toe scouring tool in relation
  • the path of the scouring tool is no longer controlled by the applied pressure, nor is it dependent upon any mechanical guidance taking place during the scouring operation by engagement of a mechanical element with the shoe bottom.
  • the shoe support preferably comprises toe end support means, a heel end support arrangement and means for effecting relative movement of approach therebetween to accommodate to the size of shoe to be supported thereby, and furthermore the toe end support means and heel end support arrangement are so arranged that a shoe is clamped thereby with the toe end portion thereof in a heightwise datum position.
  • the toe end support means preferably comprises two inclined support surface portions forming a V for supporting the toe end of a shoe, height datum means being provided against which the shoe bottom is urged, thus to determine the heightwise position of the shoe, and the inclined surface portions being mounted for adjusting movement towards and away from one another to accommodate the toe end to be supported thereby in such heightwise position.
  • the inclined surface portions are yieldingly mounted, locking means being provided for locking said surface portions in adjusted position, whereafter the height datum means can be moved to an out-of-the-way position.
  • the heightwise relationship between the shoe bottom to be scoured and the scouring tool can also be accurately controlled.
  • the shoe support includes a shoe length detecting arrangement
  • the computer control means includes a grading programme which, in response to a signal from said detecting arrangement, causes the drive signals to the numerically controlled motors, including the fourth numerically controlled motor, to be modulated in accordance with the shoe length as detected.
  • the distance over which the scouring tool is effective in operating on a shoe bottom will be proportional to the overall length of the shoe.
  • the shoe support is mounted for movement lengthwise of the shoe bottom under the control of the first numerically controlled motor, and the fourth numerically controlled motor is effective to cause the scouring tool to be moved heightwise of the shoe bottom.
  • the shoe support is preferably mounted for movement about a horizontal axis extending transversely of the shoe bottom, and thus for movement along an arcuate path, the roughing tool supporting means and the toe scouring tool supporting means being so arranged that the roughing tool is located adjacent the highest point of said path and the scouring tool just "upstream" of the roughing tool.
  • the shoe support is arranged to support a shoe with its heel end leading during such relative lengthwise movement between the scouring tool supporting means and the shoe support, so that the scouring tool is caused to operate progressively from the forepart to the toe end of the shoe bottom.
  • two shoe supports are provided arranged side-by-side, each support having a first numerically controlled motor associated therewith, two scouring tool supporting means also being provided, associated one with each shoe support, and each having a fourth numerically controlled motor associated therewith.
  • the second numerically controlled motor conveniently is effective to cause widthwise relative movement to take place between the shoe supports and the two tool supporting means to bring the latter alternately into operative alignment with each of the shoe supports, the arrangement being such that the fourth numerically controlled motor associated with the shoe support thus operatively aligned is rendered operative.
  • the apparatus now to be described is suitable for use in performing a roughing operation progressively along marginal portions of shoe bottoms, and comprises a base 10 on which are mounted two upstanding brackets 12 each supporting a pivot shaft 14, each shaft carrying a structure 16 on which a shoe support 18 is carried.
  • Each shoe support 18 is arranged to support a shoe S carried thereon, bottom uppermost, with the toe end thereof facing towards the front of the apparatus i.e. towards the operator.
  • Towards the rear of the base 10 is also mounted a support column structure 22 supporting in turn a horizontal web structure 24 by which tool supporting means generally designated 26 is carried, said means supporting two rotary radial roughing brushes 168 which are caused to rotate in contrary directions such that each brush effects an in-wiping action on the marginal portion of the bottom of a shoe as it is caused to operate progressively therealong.
  • an electric motor 300 supported by a bracket 302 on the base 10, is operatively connected thereto through a series of belts and pulleys.
  • the tool supporting means comprises a bifurcated arm 30 which is supported, for pivotal movement about a horizontal axis, in upstanding lugs 32, one arranged at either side of the arm 30, of a support casting 34, which is itself supported, above and below the web structure 24, for pivotal movement about a vertical axis.
  • either one of the shoe supports 18 can pivot about its shaft 14 to move a shoe S supported thereby in a direction extending generally lengthwise of the bottom of the shoe, while the tool supporting means is capable of pivotal movement about two axes thus to move the tools 168 supported thereby widthwise and heightwise of the shoe bottom, as the shoe support is moved as aforesaid.
  • the apparatus comprises, for each shoe support 18, a first stepping motor 144 mounted on the base 10 and effective, through a series of pulleys and belts and through a toothed segment 140 mounted on its associated support structure 16, to cause pivotal movement of the shoe support 18 to take place about the horizontal axis of the shaft 14.
  • the apparatus comprises a second stepping motor 84, carried by the web structure 24 and effective, through a series of pulleys and belts and through a toothed segment 42, to cause pivotal movement of the support casting 34, and thus of the arm 30 supported thereby, about a vertical axis on the web structure 24.
  • the apparatus comprises a third stepping motor (not shown) which is supported by the support casting 34 rearwardly of its vertical pivot, and acts on a rearwardly extending portion 102 of the arm 30, thus to cause the arm 30 to pivot about a horizontal axis provided by the mounting of the arm in the support casting 34.
  • a third stepping motor (not shown) which is supported by the support casting 34 rearwardly of its vertical pivot, and acts on a rearwardly extending portion 102 of the arm 30, thus to cause the arm 30 to pivot about a horizontal axis provided by the mounting of the arm in the support casting 34.
  • the arm 30 of the tool supporting means also supports, for pivotal movement thereon about a horizontal axis defined by pins 154, a cradle 160 (forming part of the tool supporting means) on which the tools 168 are carried, said horizontal axis being arranged to pass through the area of engagement between the operating surface of each brush 168 and the shoe bottom, in the operation of the apparatus. Pivoting the cradle 160 in this manner enables the plane of the operating surface of each brush to be maintained normal, or substantially normal, to the shoe bottom portion being operated upon.
  • the apparatus comprises a fourth stepping motor 232 operatively connected by a rod 204 to said cradle 160.
  • the apparatus also comprises two scouring tools 320 ( Figure 1) one associated with each shoe support 18.
  • Each scouring tool comprises an abrasive roll supported by a support shaft 322 on a support arm 324.
  • Each support arm 324 is pivotally supported on a transverse shaft 326, and each shaft is supported by a support column 328, the two support columns being mounted on base plates 330 secured to the base 10.
  • each support arm 324 For pivoting each support arm 324, and thus the tool 320 therewith, to bring the tool into operative engagement with a shoe bottom, each arm has an integral bracket 332 connected, by a block 334 pivotally mounted thereon, with a fifth stepping motor 338.
  • Each scouring tool 320 is caused to rotate in such a manner that its operating surface moves in the same direction as that of the movement of the shoe therepast; thus, the tool effects an in-wiping action on the toe end portion of the shoe.
  • each scouring tool 320 has associated therewith an electric motor 342 mounted on the base 10 and acting through a system of pulleys and belts.
  • Each structure 16 ( Figures 2 to 4) is made up of sections of sheet metal appropriately bent and providing four locating studs 352 on which the shoe support 18 is located.

  • the support member 362 can be pivoted about the pin 366 downwardly to an out-of-the-way position, the spring 368 thereby passing over the axis of the pin and thus serving to maintain the member in its out-of-the-way position.
  • Said casting also supports, on an upstanding lug portion 382, a heel abutment 380 which provides a "back datum", i.e. determines the position of the heel seat of the shoe to be operated upon in the shoe support 18.
  • the shoe support 18 also comprises shoe clamping means comprising a first and second set of clamps 390, 392, for clamping a shoe in the region of its featherline and in the region of its top line respectively.

  • the pin can seat in a selected one of a plurality of recesses 430 spaced apart along the outside of the arm 420.
  • Rearward end portions of the arms 420 are urged together by a spring 432, which thus urges the clamp members 426 apart.
  • clamping is not symmetrical about the longitudinal centre line of the shoe support 18, but rather the clamp members 426 can accommodate themselves to the asymmetric shape of the shoe last in the top line region thereof.

  • Said arrangement 460 is carried on a block 464 pivotally mounted on the pivot pin 366. Actuation of the piston-and-cylinder arrangement 460 is effective to cause the arm 452, and thus the holddown member 450, to move anti-clockwise (viewing Figure 2) to an out-of-the-way position.
  • a datum member 488 is provided for establishing a toe height datum.
  • This member is carried on a block 490 pivotally mounted by a pin 492 in upstanding lugs 494 of the casting 472, such pivoting movement being effected by a piston-and-cylinder arrangement 502 supported on the casting 472, a piston rod 500 of which arrangement being connected by a link 496 to the block 490.
  • the datum member 488 is pivoted to an out-of-the-way position, after a shoe S has been clamped by the first and second sets of clamps 390, 392, in order not to impede the roughing operation.
  • the casting 472 has a cut-out 504, for receiving the member 488 in its out-of-the-way position, a guard member 506 being provided to prevent trapping of the operator's finger.
