Definitions

  • Various work tools have been used to carry out operations on workpieces that travel along conveyors. These tools may include, for example, a high speed drilling tool, a waterjet cutter, a knife, a laser beam, a welding orbrazing tool, a glue dispenser, etc. Commonly the work tool may be supported for movement relative to the workpiece, e.g., transversely and/or longitudinally relative to the direction of movement of the conveyor.
  • the apparatus is composed of a transverse support structure extending across a conveyor for guiding a wheeled carriage for movement there along.
  • a second longitudinal support structure is cantilevered from the transverse carriage to extend along the length of the conveyor.
  • a second wheeled carriage moves along the longitudinal support structure to carry the working tool.
  • the wheels of both carriages are in the form of rollers that ride on rails mounted the transverse support structure and the longitudinal support structure.
  • the two carriages are powered by remotely located rotational actuators acting through endless belts, with the actuators located to the side of the conveyor.
  • the apparatus did have shortcomings. For example, to be of sufficient strength and stiffness the longitudinal support structure was required to be constructed of significant weight, thus needing large capacity rotational actuators to move the carriages at high speeds. Such weight lead to wear along the rails and of the rollers, causing the carriages to loosen on the rails, thus affecting the accuracy of the tool movement over the conveyer.
  • the rails wear more over their center area since that is where the rollers travel the most.
  • the roller wheels must be adjusted to remove the slack with the rails.
  • the adjustment of the roller wheels had to be made either relative to the more worn center section of the rail or the less worn end sections of the rail. Regardless of the selection made, the roller wheels would not be of proper adjustment for the full length of the rails.
  • the motive units used to drive the actuator are typically located away from the conveyor, or example off to one side of the conveyor. This has required a drive train of sufficient length to connect the carriages to the motive units. Since the motive units must constantly accelerate, decelerate, reverse direction, accelerate, decelerate, change direction, etc., the larger the mass of the drive train, the larger the required capacity of the motive unit as well as the drive train components.
