Definitions

  • ABSTRACT Machine adapted for working the sole contours of shoes of-any size or number whatever, including 2 copying roller, disposed at the end of a rod, journalled hingedly to an arm, whilst over said rod slides a sleeve, connected to a movable carriage, sustained by a support, fixedly secured to the tool holding arm, the sleeve displacing on the rod via a worm gear, acting on the carriage, displacing it axially relative to its support, whilst the support arm of said rod is connected to an oscillating arm, sustained by specially provided levers, journalled into one upper cross beam of the machine, the same oscillating arm being balanced by a pair of big springs and may describe a linkage motion, delivered thereto by the particular rotation of an oblong box, driven by a roller, pressing on a portion of its inner wall, said roller being keyed on a helical gear, which is controlled by a worm gear, driven in turn by a self-braking
  • the aforementioned machines differ essentially as to the type of tool with which they are provided, and which may be depending on the type of work to be carried out a cutter, or an abrasive band, or a brush and so on.
  • the aforesaid template which is shaped like the sole on which a determined treatment has to be performed, serves practically as a guide means for the displacements of the tool, by causing it to accomplish welldefined cyclic motions. It is likewise well known that the shoe soles, and hence the shoes themselves are being made depending on diversified dimensions, classified by means of a particular number. From the foregoing it may be inferred that to work and to finish the sole of each shoe size or number, it is necessary to resort to a special template, just accomplished for a determined size or number of the shoes themselves, exclusively.
  • the motion is in principle transmitted by the guide template to the tool through a frame sliding parallel to itself, along a rod, pivoted with one of its ends at fixed point and provided at the opposite end with a feeler of copying roller.
  • the aforementioned rod describes obviously a conical surface of constant geometrical characteristics, its fulcrum pin (apex of the conical surface) being fixed and its directrix, consisting of the guide or basic template, remaining unchanged.
  • fulcrum pin an of the conical surface
  • directrix consisting of the guide or basic template, remaining unchanged.
  • the machine according to the present invention is provided with a suitably oscillating arm, to which there are connected the supports for the basic template and the sole to be finished.
  • a rod at the other end of which there is journalled by means of a hinge a copying roller, which may come in contact with the contour of the basic template.
  • Over said rod furthermore may slide a sleeve, which is connected via suitable intermediate organs the tool holding arm, which during operation comes in contact with the contour of the sole to be finished.
  • the motion of the tool holding arm is, therefore, controlled by the copying roller through the sleeve fitted over the rod.
  • the tool holding arm will accomplish more or less amplified motions than those transmitted by the copying roller to the rod itself.
  • FIG. 1 shows the machine of this invention in front view
  • FIG. 2 represents the same machine as above, but in side view.
  • the machine according to this invention consists of a double frame, madeup of pairs of columns 46 and 46', 47 and 47 suitably connected by cross beams.
  • the oscillation of said arm is controlled by a box 34, driven by the rotation of a roller 35, maintained in contact with its inner wall.
  • the roller 35 is keyed on a helical gear 39, which is controlled by the worm gear 40, being rotated by the self-braking motor 41 via the belt 42.
  • the linear rotary motion of said box 34 serves to suitably adjust the forward motion of the sole onto the tool, depending on the radius of curvature of the contour portion of the sole in contact with the tool itself.
  • Said pressers clamp the sole 19 to be finished after prior centering thereof by means of two centering devices, controlled by the pneumatic cylinder 22.
  • variable angular speed rotary motion is transmitted by the box 34 to the presser group and then to the sole 19 via the chains 43.
  • said hinge is located on a line with the middle points of the template 1 and the sole being worked.
  • Over the rod 9 may slide the sleeve 8, which is connected via two small pins to a fork 7, integral with a carriage 3, provided with a suitable graduated indicator.
  • Said carriage is sustained by the support 4, fixedly secured to the tool holding arm 5, and may displace axially to the support itself because of the action of a worm gear 48, rotating via the handwheel 2.
  • the copying roller 14 is in turn sustained by the arm 15, oscillating on the levers 16 and 17, and is maintained in contact with the template 1 by the the thrust of a big spring 18.
  • the copying roller-tool holding arm group is brought close to and away from the template 1 and the sole 19, respectively, by teh action of the two big springs 30.
  • Said big springs are fastened, on the lower portion, to two levers 27 and 28, connected therebetween by a rod 29, said levers being controlled by a pneumatic cylinder 26.
  • the aforesaid tool, set in rotation by the motor 31, via the belt 49, may be replaced by a cutter, or an abrasive band or a brush, the specific functions of the machine according to the present invention being accordingly diversified.
  • Machine adapted for working the sole contours of shoes of any size or number whatever, including a copying roller, disposed at the end of a rod, journalled hingedly to an arm, whilst over said rod slides a sleeve, connected to a movable carriage, sustained by a support, fixedly secured to the tool holding arm, the sleeve displacing on the rod via a worm gear, acting on the carriage, displacing it axially relative to its support,
  • the support arm of said rod is connected to an oscillating arm, sustained by specially provided levers, journalled into one upper cross beam of the machine, the same oscillating arm being balanced by a pair of big springs and may describe a linkage motion, delivered thereto by the particular rotation of an oblong box, driven by a roller, pressing on a portion of its inner wall, said roller being keyed on a helical gear, which is controlled by a worm gear, driven in turn by a selfbraking motor via a belt, two presser means being connected to the aforesaid oscillating arm, which fasten the sole to be worked and the basic template, which imparts suitable displacements to the copying roller.
  • Machine as defined in claim 1 wherein there is provided a double frame, consisting of cross beams, whilst to two of said cross beams, placed on the upper part of the machine, there are journalled levers, which sustain an oscillating arm, balanced in its motion by two big springs, the oscillation of said arm being controlled by an oblong box, driven by the rotation of a roller, which presses on its inner wall, said box resting on two rollers, pushed against its outer wall by a spring.
