Definitions

  • the present invention relates to a machine for roughing the side edge portions of a footwear upper which are folded against the base of the last on which the upper is fitted, the machine comprising means for supporting the last with its base facing upwards, means for supporting a pair of rotary roughing tools with their operative peripheries facing the base of the last, each tool being intended to roughen a respective edge portion of the upper which extends beside the longitudinal toe-to-heel axis of the last, guide means for the movement of the support means for the last relative to the roughing tools, drive means for moving the support means for the last on the guide means, drive means for the rotary roughing tools, and electronic means for detecting the size and shape of the last, for processing them, and for sending corresponding control signals to the drive means.
  • movements are imparted to the support means for the last along the longitudinal toe-to-heel axis of the last, vertically, so as to raise and lower the base of the last relative to the opposed roughing tools, as well as transversely, that is, along the width of the last, this latter movement being necessary in order to bring the side portions to be roughed alternately under respective roughing tools provided in fixed positions relative to the central longitudinal toe-to-heel axis of the last.
  • the object of the invention is therefore to prevent the problems encountered in known machines by proposing a roughing machine which is structurally simpler and less expensive as well as being easily automated.
  • the tools with the respective conventional drive devices including electric motors 4 and 5, transmission belts 6 and 7 and pinions 8 and 9 are carried by a carriage 10 which is slidable on a pair of guide rods 11 and 12 carried in turn by the frame 1.
  • the guide rods extend perpendicular to the toe-to-heel axis PT of the last 13 on which the upper 14 is mounted for the roughing operations to be carried out on the opposite edge portions 15 and 16.
  • the carriage 10 is connected to the rods 11 and 12 by means of sliding bushes 17 and is moved by means of a male-and-female screw mechanism 18, 19 with a motor 20, the latter being fixed to the frame 1 of the unit.
  • the carriage 10 with its roughing tools 2 and 3, is moved by means of the motor 20 and the associated male-and-female screw device from a first position in which it is displaced towards the right as seen in Figure 4, in which the rotary tool 2 is in the operative position for roughing the edge portion 15 of the upper 14 to a position in which it is displaced towards the left, in which the tool 3 is in the operative position relative to the edge portion 16 of the upper 14, in accordance with the conventional operating cycle of the machine.
  • the machine In a position beneath the unit with the roughing tools 2 and 3, the machine comprises a unit for supporting and moving the last 13 with the upper 14.
  • This unit comprises a plate-shaped support 21 with end shoulders 22 and 23 to which the ends of rectilinear rods 24 and 25 extending parallel to the toe-to-heel axis PT of the last 13 are fixed.
  • the support 21 Adjacent the shoulder 23, the support 21 is fixed to the frame of the machine, which is not shown to simplify the drawing, by means of a pin 26, the axis of which is perpendicular to the toe-to-heel axis PT of the last 13.
  • the shoulder 22 is connected by means of articulated joints 27 and 28 and a rod 29 to a drive device which, in the embodiment in question, is constituted by a pneumatic jack 30.
  • the support 21 can perform angular movements about the pin 26, by the operation of the jack 30, these movements being contained within a plane parallel to the vertical plane passing through the toe-to-heel axis PT of the last 13.
  • a carriage, generally indicated 31, is mounted on the guide rods 24 and 25 for supporting the last 13 and for moving it towards and away from the unit with the roughing tools 2 and 3.
  • a rectilinear rack 32 shown in section in Figure 4, parallel to the guide rods 24 and 25, is fixed to the support 21 and also extends between the shoulders 22 and 23 of the support 21.
  • the rack is intended for moving the carriage 31.
  • the latter comprises a first plate-like element 33 which has sleeves 34 and 35 surrounding the guide rods 24 and 25 and to which a plate 37 is fixed by means of screws 36.
  • a cup-shaped element 39 is anchored on the latter plate by means of screws 38 and a motor 40 is fixed thereto, its pinion 41 projecting from the hole 42 in the plate 37 and meshing with the rectilinear rack 32.
  • a toothed circular sector 44 fixed to the plate 37 by means of screws 43, is intended to mesh with the pinion 45 mounted on the shaft of another electric motor 46 supported by a second plate-shaped element 47 forming a constituent part of the carriage 31.
  • the second plate-shaped element 47 is mounted for pivoting about an axis 48 which is perpendicular to the toe-to-heel axis PT and which, in the embodiment shown, coincides with the axis of the shaft of the motor 40, by means of an annular bush 49 and a bearing 50 which engages with the cup-shaped element 39.
  • Upright column-like portions 51 and 52 are connected to the second plate-shaped element 47.
  • the free end of the column-like element 51 has a pin 53, the inclination of which can be adjusted about a pin 54, for the connection of the heel portion of the last 13, whereas the column-like element 52 has a fork-like member 55 for supporting the toe portion of the last.
  • the fork-like member 55 has a base 56 fixed to a slide 57 by means of a screw 58.
  • the slide 57 is adjustable on the free end of the column-like portion 52 by a rectilinear movement parallel to the toe-to-heel axis PT of the last 13 by means of a male-and-female screw mechanism 59, 60, driven by an electric motor 61 with a belt transmission 62, the whole being fixed rigidly to the column-like portion 52.
  • the machine also has a conventional electronic scanner 63 for detecting the size and shape of the last 13.
  • the scanner is fixed to the support 21 of the unit supporting the last in a position in front of the roughing-tool unit so that the size and shape of the last with its upper, positioned on the column-like portions 51 and 52 of the carriage, are detected as it is transferred towards the roughing unit.
  • the data collected and processed are transformed, in conventional manner, into control signals which are sent to the motor 20 of the roughing unit in order to position it relative to the edges 15 or 16 of the upper 14 to be roughed, as well as to the motors 40, 46 of the carriage 31 and the jack 30 of the frame 21 to cause the last 13 to adopt the various positions necessary according to the size and shape detected by the scanner 63 as it passes beneath the roughing tools.
  • these positions are achieved by a combination of angular movements of the support 21 about the pin 26 and of the plate-shaped element 47 with its columns 51 and 52 about the axis 48 as a result of the meshing between the sector 44 and the pinion 45.
