  • Patent number: 9821440
    Abstract: A automatic truss jig setting system is disclosed that includes a table including a plurality of segments with a side edge of adjacent segments defining a slot. At least one pin assembly, and optionally a pair of pin assemblies, is movable independently of each other along the slot. Movement apparatus is provided for independently moving the pin assemblies along the slot. Each of the side edges of the segments associated with the slot defines a substantially vertical plane with a zone being defined between the substantially vertical planes of the side edges, and the movement apparatus is located substantially outside of the zone of the slot. The invention may optionally include a system for handling the obstruction of pin assembly movement, and a system for keeping track of the position of the pin assembly when the pin assembly has encountered an obstruction.

  • Patent number: 7076137
    Abstract: A positioning and measuring station for photoelectric elements includes a base, a platen, a five-axis driving module and a retaining member. The platen is for holding a measuring object. The five-axis driving module is located between the base and the platen for driving the platen axially with respect to X, Y and Z axes, or rotatable on a plane or tiltable against a plane relative to the base. The retaining member is located on one side of the platen to dynamically adjust the extending distance of the platen so that the measuring object may be leaned thereon for alignment to define the holding position of the measuring object on the platen.

  • Patent number: 5702213
    Abstract: A retractable registration pin to be used on the tooling plate of a printed wire board drilling machine for alignment of PWB panels on the tooling plate for drilling. In the instant invention, a soft plug which receives a registration pin is mounted on a spline shaft. The bottom of the ball spline shaft is attached to a link which is coupled to a pneumatic cylinder. The pneumatic cylinder is driven by a pneumatic valve which raises and lowers the registration pin on the ball spline assembly. The pneumatic cylinder may either fully retract the registration pin to a position below the surface of the tooling plate, or fully extend the ball spline shaft so that the upper surface of the soft plug holding the registration pin, is parallel to and lies in the same plane as the upper surface of the tooling plate. When the registration pin is in the raised position, work panels may be placed over the registration pin until a suitable number have been prepared for drilling.

  • Patent number: 5544559
    Abstract: An adjustable stop mechanism for limiting the movement of a rip fence toward the cutting plane of a tiltable panel saw as an automatic function of the selected orientation of an abutment bar. The abutment bar has first and second orientations alternately presenting an abutment face of relatively low height, located at a greater distance from a reference surface, and a relatively greater height, located at a relatively shorter distance from the reference surface. When the abutment bar is rotated to the low height orientation, as to accommodate tilting of the panel saw blade, a limit stop position of movement of the abutment bar toward the cutting plane is automatically altered, so that the limit stop for the abutment bar support is farther away from the cutting plane. When the bar is oriented to present a full height abutment face, the limit stop automatically is altered in response to such orientation, to permit the support to move closer to the cutting plane.

  • Patent number: 5092028
    Abstract: An apparatus for assembling roof trusses including a multi-section assembly table with narrow, parallel, elongated openings in each section. Jig stops are individually adjustable along these openings by respective lead screws driven by stepper motors. The motors are controlled from a computer to automatically position the jig stops in accordance with a particular truss design. The apparatus has conveyor roller carriers between the sections of the assembly table which are raised to lift a completed truss up from the table, so that it can be slid off the table.

  • Patent number: 4943038
    Abstract: A truss assembly table having a plurality of sections in succession along its length separated by openings. Each section of the table has several panels in succession separated by openings which extend across the table. Below each opening between the panels, a lead screw drives a carrier which supports a jig stop projecting above the top of the table. Each lead screw is driven by a manually-controlled power-operated device for positioning the corresponding jig stop at a selected position across the table. Power-operated lifts at the openings between sections of the table can be raised to lift a completed truss above the top of the jig stops so that it can be slid off the table laterally.

  • Patent number: 4775135
    Abstract: A machine tool employs a workpiece guidance system comprising a pair of guide assemblies each including a stop member movable along one of the X and Y axes and a clamping element for clamping the workpiece in the stop member for movement therewith. The clamping element is movable independently of its associated stop member as well as therewith, and one stop member will provide a guide surface for the workpiece as it is moved past it by the other guide assembly. In one embodiment, the clamping element is a claw or clamp in a fixed position on the stop member and which is automatically actuable to clamp the workpiece or to release the workpiece for guided movement thereby. In another, the clamp is slidably supported in the stop member for movement relative to a base element to provide clamped guiding movement for the workpiece and also can be locked in a position to fix the workpiece therefor.
