  • Publication number: 20080141838
    Abstract: A method for improved tuning of servo motors used to drive guillotine cutters on a high speed inserter machine. The tuning coefficient is continuously varied during the blade's cutting cycle. In a first step of the tuning process, a plurality of discrete positions in the blade cycle are selected for analysis of the optimal tuning coefficients. For these discrete positions, tuning coefficients are determined. After the tuning coefficients have been determined for the discrete locations in the blade cycle, the coefficients for the remainder of the blade cycle are determined through interpolation. In a preferred embodiment, linear interpolation is used. A digital filter then applies the measured and interpolated coefficients to the amplifier that controls the motor. In the preferred embodiment, the step of selecting the discrete positions includes selecting 90 degrees, 180 degrees, 270 degrees, and 360 degrees in a guillotine blade cycle.

  • Patent number: 7308816
    Abstract: A forming machine includes a first transmission mechanism connected to a cutting mechanism and a conveying clamp mechanism, a drive mechanism for driving the first transmission mechanism; and a second transmission mechanism driven by the drive mechanism for driving a feeding mechanism. The second transmission mechanism includes a driven wheel driven by the drive mechanism, a first swing member connected to the feeding mechanism and confronting the driven wheel, an eccentric pin projecting axially from the driven wheel and connected slidably to the first swing member. The eccentric pin slides relative to the first swing member while rotating along with the driven wheel so that the first swing member is swung to and fro in a cycle motion and completes one cycle for each revolution of the eccentric pin.

  • Patent number: 6763871
    Abstract: A slip cutting system sheets an infeed web into discrete articles and merges the articles to a carrier web. The slip cutting system comprises a continuously rotating cutting die having knife blades and packings consecutively around a peripheral surface. The packings cooperate with the knife blades to define a circumferential space between each packing and an associated knife blade. When a packing is at a nip with an anvil roller, the infeed web is drawn in a downstream direction. When a circumferential space is at the nip, the infeed web halts downstream motion. When a knife blade is at the nip, the knife blade sheets the infeed web. An insert station cooperates with the cutting die to longitudinally space the articles as they merge to and are propelled downstream by the carrier web. At a subsequent station, the composite web is cut to manufacture individual products.

  • Patent number: 6110274
    Abstract: A process and apparatus for producing a high-quality polycrystalline semiconductor ingot with excellent crystallographic properties are disclosed. The interior of an airtight vessel is kept in an inert atmosphere for semiconductors. A raw semiconductor material is charged in a crucible, and the raw semiconductor material is heated by an induction heating coil so as to be melted. Then the bottom of the crucible is deprived of heat for causing the raw semiconductor material to solidify, thereby producing a polycrystalline semiconductor. The semiconductor crystal grows in one direction from the bottom to the top of the crucible while the heat emission is changed in accordance with a predetermined relationship for keeping the solidification rate of the raw semiconductor material constant.

  • Patent number: 5989116
    Abstract: A meat slicing apparatus is disclosed, wherein the apparatus is capable of high-speed slicing of meat having large skeletal bones therein. The apparatus has a blade composed of a steel alloy that is approximately 5 to 10 times greater in compression strength than typical steel. The blade has an involute shape for withstanding the stresses incurred when slicing through bones having compression near that of steel, e.g., pork loin bones. The meat slicer includes a mechanism for securing a position of a meat section to be sliced so that the meat section stays in place during a slicing process, thereby reducing the risk of misalignment of the meat section with the blade. Thus, without such misalignments, there is a reduction in blade failures, shattered bones, bone fragments, and bone dust. Also, the securing mechanism reciprocates between securing the meat section for slicing and releasing it sufficiently for indexing toward the blade between slicing operations.

    Abstract: A machine for cutting coarse sod into relatively small plugs for ready packaging and subsequent transplanting, comprising an endless conveyor belt upon which comparatively large rectangular sections of sod can be deposited, so that the sections of sod can be moved intermittently toward a sod cutting device. The sod cutting device preferably is of the single pass cutter type, utilizing a plurality of elongate, closely grouped blades designed to periodically move in unison downwardly into contact with sod to be cut, with such downward cutting movements being immediately followed by an upward movement, thus to permit an advance of the section of sod without interference. I coordinate the movements of the sod cutting device with the belt advance, such that forward movement of a section of sod is in each instance prevented until the cutting blades are clear of the section of sod being cut.

  • Patent number: 4135378
    Abstract: Feeding apparatus for feeding material for a predetermined distance past a predetermined point on a feed-path comprises a pair of feed rollers, one of which is coupled to a stepping motor. A sensing means in the form of a light beam is provided on the feeding path at the predetermined point and when the material being fed intersects and interrupts this light beam, a control means for the stepping motor commences to count pulses transmitted to the motor. After a number of pulses have been counted which causes the motor to feed the material precisely to the predetermined location, the motor is stopped. The control means also has means for actuating a further apparatus (such as a crimping press) which performs an operation on the material. This control means is effective to delay energization of the crimping press is the press is not in a state of readiness for performing the crimping operation.

  • Patent number: 3957386
    Abstract: A machine for perforating corrugated tubing at accurately spaced locations includes a double chain conveyor which positively engages the tubing and is driven intermittently to advance the tubing in steps of equal length. Upon completion of each step a pair of clamping members are actuated to engage the tubing, the clamping faces of the members being shaped so as to locate the tubing positively while it is stationary. When the tubing is so located, accurately positioned sets of cutters are brought into operation so as to cut slots or holes in the tubing at the desired locations. Upon completion of the cutting stroke, the clamping members are automatically released and the conveyor advances the tubing by another step. The sequence of operations in each cycle is controlled by limit switches responsive to the positions of the conveyor, the clamping means and the cutters. The cutters may be rotary saws or rotary drills.
