  • Patent number: 5219405
    Abstract: A device for filling PET bottles employs a cam driven vertically movable carriage mounted on the outside of the liquid storage tank adjacent each filler valve inside of the tank. A bracket mounted to the lower end of each carriage has a flat plate extending horizontally under a filler valve. A bottle gripper, having an open side slot for engaging under the collar near the mouth of a PET bottle, is suspended on two bolts which extend slidably through the flat plate. Normally uncompressed springs are interposed between the heads of the bolts and the top of the plate to hold the gripper against the bottom of the flat plate. A cam lifts the carriage after the gripper engages a bottle under its collar to initiate a seal between the bottle mouth and filler valve and as the carriage continues upward by a small amount for latching to the tank. The springs are compressed and a gap forms between the flat plate and the gripper. The plate compresses the spring which generates the force to increase the sealing force.

  • Patent number: 5195684
    Abstract: The circular housing of a fiberizer mill has a rotationally driven shaft on which there is a disk haivng a conical face and spaced apart rows of teeth. A stationary disk has on its face a multiplicity of annular grooves which define teeth. There is a small gap between the tips of the rotary teeth and the tips of the stationary teeth. The gap extends at an acute angle relative to vertical plane passing perpendicular to the shaft axis so that particles being disintegrated experience a horizontal component of force. The result is that particles, after having been exploded by striking the teeth on the stationary disk, are emitted generally radially outwardly from the gap. Hammer bars on the periphery of the rotary disk are surrounded by a toothed circular breaker plate member concentric to the orbital path of the hammers on the rotary disk.

  • Patent number: 5188491
    Abstract: Feed screws are used for container filling machines in order to separate a series of approaching containers at a specific distance from each other. Feed screws for non-rotationally symmetrically shaped containers are milled with a milling tool rotating at a high rpm, the shaft of which is arranged parallel to the longitudinal axis of the feed screw that rotates at a lower rpm. To avoid feed screw flank errors, the rotating milling tool is moved up and down in an oscillating manner, so that a milling tool can be used, the contours of which agree exactly with the associated cross sectional area of the containers which are to be handled. The first shaft of the milling tool is attached to a sliding carriage, which is movably guided in an upward and downward direction by means of a crank mechanism.

  • Patent number: 5176244
    Abstract: A pair of closed loop chains running in parallelism have uniformly spaced apart paddles on them for transporting an article such as a pad between each paddle to a pad ejection station. A shaft orbits about an axis which is parallel to the direction in which the paddle conveyor is moving. The shaft carries a plurality of ejector rods which are mounted on a sleeve that is slidable reversibly axially on the orbiting shaft. After the orbiting rods collectively eject a series of pads from the paddles, the shaft continues its orbital movement until it reaches the back side of the pads again. While the rods are passing through the paddles to eject the number of pads composing a stack, the sleeve on the orbiting shaft is translated axially in the same direction and at the same speed as the paddle conveyor is moving. The sleeve is shifted by having a cam follower thereon come into contact with a stationary cam when the rods begin their passage through the spaces between the paddles.

  • Patent number: 5176494
    Abstract: A destacking/feeding system separates individual articles such as flat container blanks or trays nested in a stack. The destacking and feeding system comprises at least two pairs of opposed endless feed conveyor belts having respective vertical runs. The feed belts are spaced apart to grip opposite sides of the articles to feed them downwardly along a path to a second pair of belts or wheels which travel at a second, higher speed. The feed belts feed the stack of nested trays to the second, higher speed belts, which accelerate the lowermost articles and propel them downstream at the second speed. At the lower end of the second, higher speed conveyor, the articles are released and fall sequentially by gravity onto a waiting conveyor.
