Patent number: 4557515Abstract: A coil handling device which orientates coils on a reel between two positions, e.g., vertical axis and horizontal axis. The device is constructed to be suspended from an overhead hoist and thereby lift or lower a reel to a selected position. The device is constructed to cause the center of gravity of the reel to coincide with the axis of rotation when suspended. Therefore, the forces of resistance caused by weight are eliminated and only friction forces have to be overcome. Hence, a manual device is provided.Type: GrantFiled: November 8, 1984Date of Patent: December 10, 1985Assignee: Woodlawn Iron Works, Inc.Inventor: Owen R. Read

Patent number: 4411576Abstract: A pick and place mechanism is provided for selecting a part from a pick-up location, transporting the same to a place location, and placing it in a precise position at the place location. A part is engaged by a pair of gripping fingers which depend from a casing mounted for movement between the pick and place locations. The fingers are connected to a cam mounted for reciprocation in the casing to alternately extend and retract the fingers. The fingers cooperate with an actuating mechanism carried by the casing to engage and disengage the part in response to movement of the cam. The cam is normally biased upwardly and is actuated by a follower which is guided in a slot in the casing, and an air cylinder drives the follower and hence the casing between the pick and place locations.Type: GrantFiled: August 26, 1981Date of Patent: October 25, 1983Assignee: William I.

Patent number: 4291910Abstract: Apparatus is described for grasping hollow bodies, such as bottles, from the inside. It is particularly useful in protecting grasping equipment used in conjunction with bottle coating equipment. On a movable rod inside a housing are mounted a structure adapted to engage the rim of the bottle and grasping arms which can be inserted into the neck of the bottle. The rod is spring-biased toward a position in which the structure and the grasping arms are retained within the housing. To grasp a bottle, a force is applied to the rod against this spring-bias so as to urge the rod, the structure and the grasping arms toward the bottle. At an intermediate point on the outward stroke, the structure is released from the rod. If the structure engages the rim of the bottle after its release and before the outward stroke ends, the structure is prevented by a slider from moving back into the housing and relative movement between the rod and the structure causes the grasping arms to engage the inside of the bottle.Type: GrantFiled: December 21, 1979Date of Patent: September 29, 1981Assignee: Societe Generale pour l'EmballageInventor: Jacques Maupate

Patent number: 4121868Abstract: A gripping apparatus for lifting objects remotely utilizing three pivotally mounted gripping arms driven by integral cam followers located on extremities and roller grasping means located on their opposite extremities. The cam followers are carried in tracks, located in a rotatable can which moves the gripping arms and rollers inwardly or outwardly upon rotation of the cam by a remotely controlled bi-directional electric motor. A positioning cone centers the gripping arms over the load to be gripped thereby preventing an unsymmetrical grip which could cause inadvertant or premature release of the load. A bottom limit switch senses tension in the cables upon which the apparatus is suspended to prevent activation of the gripping fingers unless the apparatus is fully lowered, and an inertia switch senses rotation of the apparatus for preventing excessive torque on the cam by reactive torque of the motor which could cause the entire apparatus to twist.Type: GrantFiled: March 14, 1977Date of Patent: October 24, 1978Inventors: Ray E. Pierce, Gary J. Shaffer, Roger L. Belanger
