Noncondition-responsive Sorting By Contour Patents (Class 209/940)
  • Patent number: 5238124
    Abstract: The apparatus makes use of a pair of rotating combs (11-14), the discs of the second comb being interposed between the discs of the first comb and positioned at the top between fixed guide plates (17). The discs of the first comb intercept the streams of closed capsules, from which any covers not provided with shells have already been removed. The capsules are inserted by their shells between the discs of the first comb and remain suspended on said discs by their covers (C1). Only capsule shells and any crushed capsules fall through the discs of the first comb. The capsules conveyed by the first rotating comb arrive on the discs of the second comb, generally with their covers at the front.

  • Patent number: 5193691
    Abstract: A can seam inspection apparatus. The apparatus has a pathway for a can and the pathway having an inlet and a pair of outlets. There is one outlet for can with a defective seam and another outlet for acceptable cans. A releasable holding device holds the cans as the cans move along the pathway. This holding device is rotated as they move along the pathway. The cans rotate with the holding device. The holding device can be released adjacent the inlet and the outlet. The can is inspected, preferably by a roller moving around the seam, as the can rotates. If the can is found defective then the inspection apparatus includes mechanisms to open the first outlet to allow rejection of the can. If the can is acceptable the can rolls over the first outlet to the second outlet. The equipment operates at high speed and with excellent accuracy. It can operate effectively in hostile environments.

  • Patent number: 5123543
    Abstract: Apparatus for separating angel hair from bulk material includes a hollow drum which is partly immersed in the flow of bulk material and rotates in such a manner that the immersed part of the drum moves in opposite direction to the bulk material flow. The drum has an outer jacket which is provided with circumferentially spaced bores through which one end of spikes projects, with their other end being swingably mounted to a bearing member. The bearing member has a center axis which is offset to the axis of rotation of the drum so that the spikes project beyond the outer surface of the drum at their bulk material facing side while being retracted at the bulk material distant side of the drum. Thus, during a revolution of the drum, the spikes gradually move in and out of the drum.

    Abstract: In a method of fabricating a biasing plate spring for a wire dot print head having an annular part and a plurality of projections extending radially inward from the inner periphery of the annular part, a biasing plate spring intermediate product having two of the projections substantially opposite to each other and connected by an arm, is first formed. The intermediate product is then barrel-polished, and then the arm is removed by cutting. Because of the arm, entry of one intermediate product into the gap between adjacent projections of another intermediate product is prevented, and damage to the intermediate product is thereby avoided.

    Abstract: A feeder device is provided for inserting solid medicaments, such as caplets, into a holding fixture for subsequent processing, for example, dipping in a gelatinous material. The feeder device incorporates a novel selector for eliminating partial pieces of medicaments before these pieces can be disposed into the holding fixture. The disclosed simple mechanical selection apparatus can eliminate these pieces efficiently prior to costly additional processing steps. Also included with this invention are novel mechanisms for regulating the flow of medicaments from a hopper to a plunger assembly, whereby a single medicament at a time can be inserted into a corresponding holding fixture.

  • Patent number: 4624369
    Abstract: Slide fasteners are fed longitudinally one at a time along a path by at least one stream of air flowing along the path, and are then introduced into a clearance or gate which is narrow enough to prevent the passage of sliders so that when the slide fasteners have respective sliders, they are stopped at the gate, while when the slide fasteners have no sliders, they are allowed to pass through the gate and be further advanced by the stream of air. Thus the slide fasteners are automatically sorted or separated into two groups according to the presence of the sliders. Thereafter, the stream of air is interrupted whereupon the slide fasteners stopped at the gate are allowed to fall from the path into a container disposed below the gate. The slide fasteners thus fallen are disposed in the container in juxtaposition.

    Abstract: A method and apparatus for separating the spheres from the non-spheres in a large number of particles of lamp fill material of substantially equal mass in which the spheres are placed in the grooves of an inclined surface to roll downwardly thereon under the influence of gravity. The grooves are configured to limit the contact with the particles to two points intermediate the depth of the groove so as to keep the particles out of contact with the bottom of the groove. Vacuum pick-up means are used to remove those particles which do not roll down the grooves because of their spherical irregularities. The surfaces in contact with the lamp fill material are made of stainless steel and the entire operation is conducted within the confines of a dry box to minimize contamination.

  • Patent number: 4341311
    Abstract: A method of sorting rivets or similarly shaped articles, and apparatus therefor. Rivets are directed along a track to a notch where they are supported in a shank-down attitude against a rotating gauging wheel having a plurality of gauging holes conforming generally to the shape of the shank. The wheel is rotated so the gauging holes move upwardly with respect to the shanks while grooves in the periphery of the wheel guide the shanks toward the holes. Rivets with a uniform shank will settle into the holes so their heads are below the periphery, while rivets with bent, gouged, burred or oversized shanks will not settle fully into the holes. A rivet kicker timed to the rotation of the wheel ejects rivets not fully settled in the holes. Fully settled rivets are blown out of the gauging holes into a tube where they are conveyed by air towards a riveting machine.

Such diodes (12 and 13) are successively introduced between sidewalls (11 and 22) of a bin (17) having a magnetic field which orients each article transverse to guide members (28 and 29) extending lengthwise of the bin (17). Each oriented diode (12 and 13) presents a distinctive configuration according to its shape when viewed against a plane transverse to the guide members (28 and 29). The major portion of a bent diode (13) will be disposed lower than the major portion of a straight diode (12).
