  • Patent number: 4445608
    Abstract: A bucket wheel for a bucket wheel unloader has a series of buckets mounted on pivots around its periphery so that the buckets can be displaced between opposite end positions to correspond with either direction of rotation of the wheel. Latching means engage the buckets to retain them in their required end positions and operate automatically when the direction of rotation of the wheel is reversed.

  • Patent number: 4434888
    Abstract: The invention relates to an apparatus for supplying a conveyor of an article sorting machine. It also relates to a method for using this apparatus. The apparatus essentially comprises a storage system (1) constituted by a plurality of belts (t.sub.1 . . . t.sub.n) and a tilting chair-like support (2) able to occupy a raised position (P.sub.1) and a lowered position P.sub.2. The articles are placed on the first belt t.sub.1 only when the latter is completely free of articles and when the following belt is also free. Movement of the said belt is then commenced. Movement of each of the following belts is only commenced when the belt following it is free. The final belt t.sub.n is put into movement when it carries an article and when the support (2) is free and in the raised position P.sub.1. When a free rack (4) of conveyor (5) arrives at the right of the support, tilting takes place and the article then drops into rack (4).

  • Patent number: 4433776
    Abstract: A conveyor apparatus for receiving and transporting cylindrical stock or articles past work stations includes a plurality of rollers disposed along spaced-apart parallel axes. The rollers are driven through one-way or overrunning clutches and rotate cylindrical stock disposed between adjacent pairs of rollers. At a work station, a moving member such as a belt engages the stock and rotates it at a speed higher than the speed imparted to it by the rollers. The overrunning clutches release the conveyor rollers and rotate with the stock at a correspondingly higher speed. The constant, non-slipping contact between the rollers and stock minimizes such difficulties as scoring of the stock and significantly improves product quality and appearance.

  • Patent number: 4433774
    Abstract: An improved conveyor system for transporting die-cut blanks from a rotary die cutter to a blank stacking device includes a blank take-up section comprising a spring biased take-up guide which insures that blanks are positively engaged by the conveyor system before they are released by the die cutter. The conveyor system includes a vacuum belt which serves to suspend and transport die-cut blanks while maintaining them in precise registry to a blank stacking device. An improved snubbing device is disclosed which decelerates blanks without damage to the blanks themselves and then causes the decelerated blanks to rebound back toward the die cutter for improved stacking. A ramp structure is disclosed which flexes blanks near the blank release section of the conveyor system such that the trailing edge of transported blanks snap away from the conveyor system, thereby positively disengaging the blanks from the conveyor.

  • Patent number: 4429783
    Abstract: A scraper blade assembly for use in a central chain scraper conveyor, especially in a double central chain scraper conveyor, includes a lower and an upper blade part forming respective channels that complement each other at a parting plane between the blade parts into openings for receiving transversely spaced portions of respective horizontal links of the chains. The blade parts have overlapping portions one of which extends across the parting plane and is received in a correspondingly configurated recess juxtaposed with the other overlapping portion. The overlapping portions are provided with aligned holes at least one of which is elongated in direction normal to the parting plane, and bolts extend through these holes parallel to the advancement direction of the conveyor to connect the blade parts to one another.

  • Patent number: 4424895
    Abstract: An apparatus for feeding mats to a press, e.g. for the production of particleboard or the like, comprises a feed conveyor with a discharge nose which lies in a plane tangent to the plane of a receiving conveyor entraining the mat into the press. Between the pick-up side of the receiving conveyor and the discharge end of the feed conveyor, this plane is tangent to a drum whereby press underlays are positioned beneath each mat with a head bar disposed ahead of the leading edge of the mat. According to the invention, the surface of the conveyor is provided with recesses to receive each bar so that the latter lies at least in part inwardly of the circumference or periphery of the drum while an underlay sheet lies along a drum surface which progressively merges with the circumference from this recess, i.e. is progressively asymptotic. When the recess is fixed, it can have a flank ahead of the bar against which the bar is positioned.

  • Patent number: 4412609
    Abstract: A transport system for transporting fixtures adapted to hold a workpiece sequentially from a fixture transferor station to a fixture transferee station. A fixture guide rail interconnects the two stations and is provided with a chain guide recess that extends from one station to the other. A continuous plastic timing chain cable is mounted on a plurality of sprockets so that the chain can be made to rotate. The sprockets are positioned so that the timing chain is positioned in the chain guide recess. Drive pins are mounted in selected ones of the links of the chain so that the pins will project from one side of the chain. The drive pins initially contact a fixture positioned in the transferee station and move each fixture, in turn, along the guide rails to the transferee station. A drive motor is connected to one of the sprockets to cause the sprocket to move the chain. The distance between drive pins is substantially constant and greater than the corresponding dimension of the fixtures being transported.
