Patent number: 4738349Abstract: An automatic spring feeding device is shown which uses a three-sided feedbox having a movable bottom panel for urging a series of springs into rotating bundles against a moving platen which forms the fourth side of the feedbox. The platen is grooved with specially shaped grooves which capture individual springs therein under the urging of a magnet on the opposite side of the platen from the springs. The platen is then carried by a continuous drive chain to a spring feed assembly where the springs are loaded one at a time into a channel from which the springs are metered by a solenoid operated release door. The key to handling the springs without tangling them is to wind each end of the spring with a closely wound coil. After the springs are placed upon a conveyor belt, the unwanted closely wound coil or coils may be removed by a suitable shear.Type: GrantFiled: September 25, 1986Date of Patent: April 19, 1988Assignee: The Gillette CompanyInventor: William H.

Patent number: 4396108Abstract: Individual assembly parts are separated from a coherent mass of the parts resting on a support by randomly sub-dividing the mass into clusters by continuously and successively lifting randomly selected clusters off the support and dropping the lifted clusters thereon until the mass is resolved into clusters and the clusters are further resolved. The continuous and successive lifting and dropping of the clusters causes continuously changing portions of the mass and clusters to rest on the support and the support is continuously and successively relieved of the weight of the randomly selected lifted clusters of assembly parts. The resolved clusters are singled into individual assembly parts and the individual parts are removed from the support to a conveyor where they are oriented.Type: GrantFiled: December 16, 1981Date of Patent: August 2, 1983Inventor: Walter Sticht

Patent number: 4369874Abstract: In many branches of industry large quantities of small items (e.g., wire components) or assembly components are frequently required, which have a strong tendency towards entangling and which conglomerate in a pile. These components, termed entangled components, can be isolated only with great difficulty when required for processing. This invention provides a device for isolating such entangled components with relative ease. For this purpose, a horizontal disentangling plate (1) is provided on which the entangled components (7) are placed. A vibrating device (2) shakes the disentangling plate (1) in a reciprocal motion in vertical direction, thus enabling the entangled components (7) to become isolated.Type: GrantFiled: February 13, 1980Date of Patent: January 25, 1983Inventors: Hans Kettner, Odo Hutter

Patent number: 4220257Abstract: A separator for springs and similar parts has a housing provided with an opening for facilitating feeding of tangled springs into the housing. A striker assembly, in the form of a disc arranged opposite the opening in the housing and provided with one or more blades, imparts energy to the tangled springs. The inner surface of the housing has a plurality of protuberances, and the like, for promoting a spinning action of springs energized by the striker assembly. Free fall of tangled springs into the path of the striker blades sets up a natural vibration or oscillation of the tangled springs that, due to the contact angle along the radius of the spring wire, drives them apart. Further, the striker blades impart a rotating motion to the tangled springs in conjunction with the traction imparted to the springs by the protuberances on the inner surface of the housing when the springs come off the striker blades.Type: GrantFiled: July 27, 1978Date of Patent: September 2, 1980Inventor: John E.
