  • Patent number: 8128323
    Abstract: A driven tool assembly that uses the cutting tool coolant to also lubricate and cool the driven tool. The driven tool housing has at least one coolant intake port, at least one coolant discharge port, and a shank for mounting the driven tool assembly to a machine tool. An input shaft and an output shaft are rotatably mounted in the driven tool housing, and a transmission transmits power from the input shaft to the output shaft. A seal is disposed between the housing and the input shaft. Typically, at least one passageway fluidly communicates the coolant intake port with the input shaft, the output shaft, the transmission, the bearings, and the coolant outlet port.

  • Patent number: 7196290
    Abstract: A heat sealer having a heated platen, a cylinder for reciprocating the platen, a die positioned to be engaged by the platen and a shuttle supporting the die to move the die from a platen-engaging position to a non-engaging position, and a control for controlling the temperature of the platen and the force applied to the platen against the die by the cylinder. The invention also includes a temperature sensor for sensing the surface temperature of the platen and a load sensor for sensing the force applied by the platen to the die. In one embodiment, the temperature sensor is an infrared temperature sensor that reads the surface temperature of the platen and the load sensor is a load cell positioned beneath the die and supporting the die so that the load sensors can measure the direct force applied by the platen against the die. Also, in one embodiment, the infrared sensor is positioned beneath the die so that it can read the platen temperature when the die is displaced to the non-engaging position.

  • Patent number: 5871080
    Abstract: A product aligning system specially adapted for receiving and aligning product items in bulk quantity, includes a hopper for receiving masses of product items in bulk and including a hopper conveyor extending across the bottom of the hopper, a hopper nose conveyor for receiving product items conveyed by the hopper conveyor and extending outwardly from the hopper, and a scale conveyor for receiving items from the hopper nose conveyor. The hopper nose conveyor and scale conveyor each include powered rakes positioned above the item supporting surfaces of those conveyors such that substantially only a single layer of items passes therebeneath. The hopper nose and scale conveyors each include load sensing apparatus which detects an accumulation of product items on those conveyors and signals a computer control which slows the speeds of the hopper and hopper nose conveyors sufficiently to allow the accumulation of products to reduce.

  • Patent number: 5551550
    Abstract: An article accumulator is designed for use with a robotic hand. The accumulator comprises an open frame having an endless open conveyor for receiving and transporting individual aligned rows of generally flattened articles such as frozen burger patties. A receiving section of the accumulator initially receives the flattened articles in rectilinear rows. The rows of articles are then passed to a pick section of the accumulator. Operably associated with the pick section are a repositioning system and a lifting system. The repositioning system comprises an actuator, a set of plate members with vertically extending fingers, and a stop fence. The plate members are positioned below the open conveyor so that upon programmed activation, the plate members move upwardly a sufficient distance that their fingers encompass a number of articles. The fingers ensure that the articles are properly positioned. The lifting system is also positioned below the endless open conveyor holding the articles.

  • Patent number: 5403056
    Abstract: A robotic hand on a robot is capable of picking-up several generally flattened articles in a stack form in a gentle non-damaging manner. The robotic hand has a manifold for directing controlled pressure air and a set of gripper finger assemblies extending therefrom. Each finger assembly has a rigid finger support member and an inflatable bladder extending along its length. The bladders are in communication with the chamber of the manifold and an external source of positive and negative pressure air. The robotic hand is capable of positioning itself over an article to be picked-up with the set of gripper finger assemblies encompassing the article. Pressurized air is directed through the manifold and into the bladders of the finger assemblies. The bladders expand sufficiently to grasp sides of the article.

  • Patent number: 4517893
    Abstract: Apparatus is disclosed for the production of silk screened textile goods. Workpieces are positioned on pedestals of a conveyor at a printing station and a silk screen design is then printed thereon. Cyclical operation of the conveyor incrementally advances the printed workpieces to a "drying" station where the printed designs is converted to solid form. The ink employed is plastisol based and is converted or "dried" to solid form primarily through polymerization. The "drying" station employs a heater element which selectively emits infra-red radiation spectrally limited to a wavelength range of three to four microns, a wavelength range at which the liquid plastisol exhibits a peak of radiation absorption. Operation of the conveyor is responsive to the rate at which an operator silk screens the workpieces with means being provided to retract the heater element from its operative position if this rate falls below a predetermined pace in order to avoid over exposure of the workpiece to the infra-red radiation.
