Plural Work Stations Patents (Class 408/34)
  • Patent number: 11072500
    Abstract: A rotary indexing transfer machine includes a machine frame; a rotating table, supported on the machine frame to rotate about an indexing axis; at least one workpiece carrying spindle having a hollow shaft for receiving a workpiece and a clamping device for clamping the workpiece inserted in the hollow shaft. The clamping device includes a collet is coupled to the workpiece carrying spindle. The workpiece carrying spindle is mounted on the rotating table, and the hollow shaft and collet are connected for joint rotation about a spindle rotation axis. The machine includes at least one support in fixed position next to the rotating table, at least one machining station with at least one machining unit supported on the support, to allow machining of the workpiece clamped in the collet. The machine includes at least one drive motor mounted on the rotating table, an indexing device mounted on the machine frame, and an indexing component.

  • Patent number: 7065856
    Abstract: A machine tool apparatus is provided employing a plurality of tool heads which may be sequentially or simultaneously automatically controlled to perform preprogrammed operations on either the same or different workpieces. In one form, a plurality of tool heads are supported on the same frame, guideway or track and may be separate prepositioned or driven under remote or automatic control to perform preprogrammed operations wither in sequence or simultaneously on the same workpiece or simultaneously on separate workpieces spaced apart on a common conveyor such as a flight conveyor while the conveyor is either in motion or stationary. In another form, the conveyor is automatically stopped with units of work thereon, each disposed so as to be predeterminately located with respect to a respective machine tool which has been prepositioned adjacent the work-holding conveyor.

  • Patent number: 6764434
    Abstract: A machining center comprising at least two workstations. A first workstation is adapted to receive a first workpiece, and a second workstation is adapted to receive a second workpiece. The first workstation may be a vacuum table, and the second workstation may be comprised of a plurality of hold-down bars. A carriage is adapted to travel between the two workstations in one machine cycle. The carriage may have a single tool or a plurality of tools. During the machine cycle, the carriage is adapted to perform a machining operation (e.g., routing, drilling, sawing, and/or sanding) on the workpiece at each workstation.

  • Patent number: 6688352
    Abstract: The invention relates to a work center for wood working including: a support base (1) for the pieces to be worked; a structure (6), mobile along said base in the direction of a first numerically controlled axis (X); a support (12) of a tool group (13) mounted on said structure and mobile, under numeric control, along a second axis orthogonal the first two, wherein a second tool group (15) is provided, mounted on said support (12), said second tool group (15) being mobile between a first position in which it fits completely within said support (12) and a second position in which said second tool group protrudes from the said support (12). According to a second preferred embodiment, the machine includes, mounted onto the same structure (6), a second carriage mobile along said second axis and supporting a second tool group mobile along said third axis (Z) orthogonal to the first two.

  • Patent number: 6142196
    Abstract: A machine for forming a bottom rail and a valance for a window blind unit. The machine has a support member upon which a length of wood ultimately destined to be a bottom rail or a valance can reside while cutting occurs, and includes at least one laterally movable saw blade for cutting a selectable wood segment at a selectable angle up to 90.degree.. Such angular cutting permits a mitred junction of corners in a formed valance. The machine also has at least one wood boring device and at least one wood drilling device to provide for pull cord anchoring whereby cords are passed through a drilled aperture and knotted such that the knot is housed in a bored compartment. The machine can be incorporated and automated for inline inclusion with automated components of a window blind manufacturing and assembly system to provide finished bottom rails and packaged valance components for final installation at a site of use.

  • Patent number: 4898501
    Abstract: A rotary drilling machine for forming holes of selected size and spacing in continuous strip material such as elastomeric gasket stock used for the manufacture of gaskets for door openings and the like. This machine has a rotary drum unit which carries the strip material along a portion of its peripheral edges. A plurality of drilling units are mounted on this drum unit so as to move with the strip material. The drilling units are oriented toward the peripheral edge, and these drilling units are moved radially in a proper sequence whereby drill bits thereof move toward the strip material to dril the holes and then retract. Tensioning elements produce friction between the strip material and the periphery of the drum unit to accomplish the movement thereof in unison. The tensioning elements, in a preferred form, have signal generating elements whereby the speed of rotation of the drum unit is controlled to prevent sag in the run of the strip material.

  • Patent number: 4219293
    Abstract: A machine for perforating workpieces, particularly corrugated plastic drain pipe or tile, to produce holes using drills is described. Multiple drills are radially mounted on a guide wheel so that the individual drills are sequentially extendable from the periphery of the guide wheel into the workpiece as the guide wheel rotates against a surface of the workpiece. A motor rotates a drive disc which as the guide wheel rotates sequentially contacts a cylindrical bushing on each drill to extend and rotate the drill into the work surface to create a perforation or hole and the drill is then extracted from the perforation by the rotation of the guide wheel.
