Definitions

  • the present invention relates to coin extractor loaders comprising a carriage movable horizontally along a fixed frame, and a slide which is movable vertically relative to the carriage and carries a support provided with gripping means suitable for gripping a part.
  • These extractor loaders are used to move parts, such as tubes, for example from one press to another for stamping operations.
  • extractor loaders with a single motor which comprise an element pivotally mounted on the carriage and connected to the slide so that a pivoting of the element causes this slide to move relative to the carriage, means for preventing the element to pivot when the carriage is in the central part of its travel, and a motor which is fixedly mounted on the frame and is connected to the carriage thus ensuring horizontal movement of this carriage, as well as to the pivoting element so to ensure a vertical displacement of the slide when the element can pivot, (see for example FR-A 1.397.689 and FR-A 2.439.068.
  • the present invention relates to an extractor loader of the above type, the production of which is particularly simple.
  • the extractor loader is characterized in that the pivoting element consists of a pulley framed by two toothed wheels and integral with these wheels, in that a toothed belt has one of its ends wound on at least half a circumference on the pulley when the carriage moves horizontally, being fixed to the rim of this pulley, and at its other end connected to two chains crossing the first end of the belt and arranged on either side of. the latter, in that these chains are wound on the toothed wheels according to at least half a circumference when the carriage moves horizontally, and in that the traction element constituted by the toothed belt and the chains passes over an element drive connected to the motor and to a return element.
  • the pulley-cogwheel assembly can be connected to the slider by a crank whose axis is integral in rotation with this assembly and which is articulated on one end of a connecting rod whose other end is articulated on the slider .
  • the means for preventing said element from pivoting can comprise a lever integral in rotation with this pivoting element and carrying rollers rolling on a fixed horizontal rail, the latter carrying at the desired location, or at each desired location, a cam with which the rollers cooperate by allowing the lever to pivot.
  • the lever can for example carry at least three rollers, one of which is located in the axis of the pivoting element while the other two are provided at the ends of the lever, the cam having a central groove and two grooves in an arc in which the first roller and the other two can engage respectively.
  • the lever may have a T-shape, its central branch carrying at its end a fourth roller capable of engaging in a groove in an arc of a circle of the cam, which is coaxial with the other two grooves in an arc of a circle. This roller allows the lever to resist the force exerted by the traction element of the pivoting part when the first three rollers are in the vertical position.
  • the extractor loader comprises a fixed frame 1 on which a carriage 2 is mounted to move horizontally.
  • the carriage carries support and support rollers 3a, of horizontal axis, which roll on a rail 4, and lateral guide rollers 5, of vertical axis, which roll on the rail 4 and on a rail 6, the rails 4 and 6 being integral with the frame 1.
  • the carriage 2 can move vertically a slide 7 which is guided by rollers 34 and carries a support not shown and provided with gripping means for gripping a part to shift.
  • An axis 8 is rotatably mounted in the carriage 2 by means of bearings 9. On this axis is keyed a pulley 10 on either side of which are fixed toothed wheels 11.
  • the axis 8 is integral with a crank 12 articulated at 13 to a connecting rod 14, the foot of which is articulated at 15 on the slide 7.
  • a toothed belt 16 passes over a drive pulley 17 whose axis is connected by a bevel gear 18 to a drive motor 19; it also passes over a return pulley 20.
  • the upper strand of this belt passes directly from the drive pulley 17 to the return pulley 20.
  • One end of the lower strand is wound on the pulley 10 over approximately 180 ° as indicated in ABC in Figure 3, and is fixed in C on the rim of this pulley.
  • the other end of this lower strand is extended by two lateral chains 21 which pass over the toothed wheels 11, following the path ADC, and are fixed to these wheels on the same generator C of the pulley 10.
  • the end of the axis 8 opposite the crank 12 carries a roller 22 and is integral with a lever 23 which carries at its ends two rollers 24 and 25, the axes of the rollers 22, 24 and 25 being located in the same plan. These rollers roll on a horizontal rail 26 fixed to the frame 1.
  • the rail 26 carries a cam 27.
  • This cam has a horizontal groove 28 and two grooves in an arc 29 and 30 which are directed one upwards and the other downwards. These grooves are connected to the groove 28 in places separated from each other by a distance equal to that separating the axes of the rollers 24 and 25.
  • the lever 23 is integral with a lever 31 which is perpendicular thereto and carries a roller 32.
  • the cam 27 has a groove 33 concentric with the grooves 29 and 30 and disposed symmetrically with respect to the groove 28. It is arranged so that the roller 32 is engaged therein when the rollers 24 and 25 are engaged in the grooves 29 and 30.
  • the rollers 22, 24 and 25 and the rail 26 constitute a locking device which normally prevents the axis 8 from pivoting.
  • the motor 19 rotates by driving the belt 16
  • the torque exerted on the pulley 10 is canceled out by the reaction of the rail on the rollers 22, 24 and 25 and the force is transmitted to the axis of the pulley 10 which drives the carriage 2 in translation, on guide rails 4 and 6.
  • rollers 22, 24 and 25 respectively engage in the grooves 28, 29 and 30.
  • the axis 8 can therefore pivot, while continuing to advance, and the crank 12 causes the slide 7 to move vertically. relative to the carriage 2.
  • the roller 32 engages in the groove 33 and balances the force of the belt 16 on the pulley 10 when the lever 23 is in the vertical position.
