Definitions

  • These machines generally consist of one or two rotating circular tools with an abrasive peripheral edge.
  • the tools are guided so as to travel along the lateral edge of the bottom in order to perform the required roughening operation.
  • the general aim of the present invention is to overcome the abovementioned drawbacks, providing an automatic machine for scraping and roughening shoe bottoms, which does not give rise to abnormal stressing or distortion of the edge of an upper being worked on.
  • a machine for roughening the bottom of a shoe along its peripheral edge comprising a shoe support and a working head with a disc-shaped roughening tool which rotates in one plane and has a peripheral rim for working the bottom of the shoe, the shoe support and the working head being movable relative to one another so as to cause the tool to follow a predetermined trajectory along said edge, characterized in that the tool is supported by orienting means so as to be arranged with the plane of rotation inclined at a predetermined angle with respect to the lateral profile of the bottom during the movement of the tool along said trajectory.
  • a machine according to the invention is diagrammatically indicated by 10 in Figure 1.
  • This machine comprises a first pair of vertical guides 11 and 12 for vertical travel of a motor-driven slide 13 which supports in turn a second pair of guides 14 and 15, along which a second motor-driven slide 16 supporting a working group or head 17 travels horizontally.
  • the three pairs of guides thus form a system of orthogonal Cartesian axes by means of which it is possible to perform any relative translatory movement of the shoe 25 and working group 17.
  • the working group 17 comprises a vertical sleeve 26, rigid with the slide 16, inside which a support arm 28 is rotatable about a vertical axis 32 substantially perpendicular to the plane in which the shoe bottom extends. Rotation of the arm 28 about the the axis 32 is effected by an adjustable-position motor unit 27, for example a stepper motor or a d.c. motor with a position encoder.
  • an adjustable-position motor unit 27 for example a stepper motor or a d.c. motor with a position encoder.
  • the support arm 28 pivotably supports at one of its ends an arm 30 which supports at its free end a rotating tool 29 with an abrasive peripheral edge, for example a metal brush or the like.
  • the end 38 of the arm 30 which supports the brush 29 is hinged with the arm 28 by means of an articulated joint 36, such that the arm 30 is able to move about an axis 31 in a plane parallel to the plane of the brush and about an axis 34, perpendicular to the axis 31 and substantially tangential with the bottom edge of the brush, so as to allow lateral inclination of the brush plane.
  • the vertical axis 32 intersects the axis 34 in the vicinity of the point of tangency of the brush with the axis 34.
  • the movement of the lever 30 about the axis 34 is effected by a linear actuator 45 arranged between an extension of the support 28 and the free end of the articulated joint 36.
  • a resilient element 40 (for example an air spring) is located between the arm 30 and articulated joint 36 in order to maintain the lever 30 resiliently in a predetermined angular position with respect to the axis 34.
  • the working surface of the tool 29 can be moved along a predetermined path following the pattern of the bottom of the shoe in both a horizontal and vertical plane.
  • the plane of the tool can in fact be kept inclined at a predetermined angle with respect to the lateral profile of the bottom, viewed in the horizontal plane, by means of operation of the motor 27.
  • the plane of the tool can moreover be kept inclined laterally by means of the actuator 45, so as to remain correctly oriented with respect to the bottom of the shoe, viewed in a vertical plane, even along the sloping sections.
  • the machine described above comprises a unit 46 for controlling and managing operation, said unit being connected to the driving systems of the slides 13, 16 and the carriage 20, to the motor 27 for vertical rotation of the support 28, to the linear actuator 45 and to the grippers for holding and positioning a shoe in the carriage 20.
  • the control unit 46 may be, for example, a programmable electronic processing unit, such as a microprocessor for example.
  • This electronic unit is of a well-known type and hence can be easily imagined by a person skilled in the art, especially in the light of the operating description which follows. Consequently, it will not be described or illustrated further herein.
  • the path and angles which the tool must follow or assume during the working operation may be entered into the unit 46, for example by means of a keyboard 47 or other known instructing means.
  • control unit may be programmed so as to calculate directly rotation of the tool about the axes 32 and 34 on the basis of the movement data relating to the front and rear end of the shoe.
  • Figure 3 shows, by way of example, the inclination of the tool about the vertical axis 32 along various points of a trajectory 24 representing the edge of a hypothetical shoe, so as to keep the action of the tool directed towards the inside of the edge of the upper and in a direction perpendicular thereto.
  • Figure 4 shows an example of a working operation in which the working plane of the tool is inclined at predetermined variable angles depending on the position of the tool along the edge of the bottom.
  • the tool forms an angle ⁇ of about 90° in the region of the central, toe and heel zones of the bottom, while it forms an angle ⁇ less than 90° in the intermediate connecting zones.
  • ⁇ of about 90° in the region of the central, toe and heel zones of the bottom
  • ⁇ less than 90° in the intermediate connecting zones.
  • the tool is rotated so as to push the upper towards the centre of the bottom, i.e. in an anti-clockwise direction as viewed in Figure 1.
  • the brush is resiliently supported by means of the spring 40, so as to exert an adequate pushing force on the bottom of the shoe.
  • the articulated joint 36 may be different from that shown. In particular, it may be dispensed with if inclination of the tool in a vertical plane about the axis 34 is not required.
  • the carriage supporting the shoe may be provided with sensors which measure the dimensional characteristics of the shoe so as to indicate to the unit 46 the model and/or the size of the shoe, such that this unit is able to choose between several preset trajectories (one for each model to be handled) or can calculate a scale factor of a preset trajectory so as to adapt it to a different shoe size.
  • the sensors may indicate the presence of a right-hand or left-hand shoe or mirror-reverse the trajectory to be followed. These sensors may be simply inserted into the shoe positioning grippers in order to measure displacement of the grippers themselves prior to gripping as can be easily imagined by a person skilled in the art.
