  • Patent number: 6427831
    Abstract: A conveyor bed has opposed sides and transverse nose bars on the ends of the sides to form an open frame. The sides carry also rungs. Elongated wear strips lay on the rungs to form a deck for a conveyor to slide thereon. The ends of the sides are formed with open mortises. The nose bars extend between opposite lateral ends formed a T-headed tenons. The tenons releasably couple with the open mortises. Hence the nose bars are adapted to couple onto the ends of the sides be locked there by the felt weight of the conveyor rolling over the nose bars. The elongated wear strips have an upper edge forming a conveyor supporting surface and a lower edge formed with notches. The notches are sized for receiving the rungs. Thus the notched wear strips are adapted to be weighted down in place on the rungs by the weight of the conveyor sliding thereon. The notches are sized for closely fitting the rungs to better stabilize the wear strips from unwanted displacement.

  • Patent number: 6298982
    Abstract: An external guide assembly for reducing the frictional drag force acting on a side-flexing modular link conveyor belt, particularly along curves or bends in the conveyor system. The guide assembly is formed from one or more roller assemblies, each having first and second rollers that provide external bearing surfaces for the forward and return runs of the belt. The rollers prevent the belt from drifting to the inside of the curve, and thus serve to reduce the frictional drag force between the belt and the guide rail on the outside of the curve. To form the guide assembly, pairs of articulated members interconnect the roller assemblies and allow the relative angular position of each to be selectively adjusted for mounting along any curve. The rollers may optionally include a peripheral lip which provides additional support for the guide links of the belt.

The concave recess does not penetrate through the surface to the rear face, but serves to accumulate the abraded powder or similar therein.

  • Patent number: 5988360
    Abstract: A load zone area of a conveyor system which includes a continuous belt which carries bulk materials such as stone, ore, grain, etc. to a discharge point where the material leaves the belt as the belt wraps around a head pulley and returns along the under side of the conveyor system to a tail pulley which brings the belt back to a point which it can be loaded again. The load zone area typically has multiple support rollers closely spaced together to minimize the effect of the material impacting the belt which deflects the belt downward, thus creating a gap between the belt and the skirt seal causing leakage.

  • Patent number: 5927478
    Abstract: An input station for a wide continuous conveyor belt that moves in a conveyor run through an input station to a discharge location, around a head pulley, through a return run around a tail pulley, and back into the input station. At the input station the belt rides on a plurality of N conventional central support rollers each mounted between two inner stanchions. A plurality of at least 2N elongated, flat, stationary slider rails support each extreme outer edge of the conveyor belt through the input station. There are 2N troughing rolls, one at each end of each central roller, between the slider rails and the central rollers. 2N fixed inner stanchions support each central roller and one end of each of its troughing rollers. 2N fixed medial support members each support one end of a troughing roller. The slider rails are supported by the medial support members and by 2N outer stanchions.

  • Patent number: 5904240
    Abstract: An elongated low profile sheet metal tray has a bottom panel adapted to seat on the bolster plate of a stamping press under a die set. The panel supports adjacent upper and lower runs of an endless belt directed around guide rollers and a drive roller supported by cast support members removably connected to opposite ends of the tray. A motor and gear reducer unit is mounted on one support member and drives the belt drive roller, and the sheet metal tray has opposite integral side rails forming inclined surfaces and channel portions enclosing opposite edge portions of the belt. A sheet of plastics material extends between the bottom panel and the bottom run of the belt, and a detector senses belt stoppage for stopping the motor and stamping press.

  • Patent number: 5875697
    Abstract: A conveying apparatus is disclosed for conveying a food product having a wide variety of sizes and propelling the food product through a stationary knife assembly to cut the food product into discrete pieces. During the conveying of the food product, and elongated food product will be oriented such that its longer dimension is generally parallel to the conveyers before it encounters the cutting apparatus. The conveying apparatus utilizes a pair of endless belt conveyers oriented such that a run of one conveyer is located adjacent to a run of the other conveyer in order to grip a food product between the facing runs of the endless belt conveyers. A drive mechanism drives both of the endless belt conveyers at substantially the same speed so as to propel the food product through the stationary knife assembly. The conveying apparatus automatically adjusts to accommodate a wide variety of food product sizes by way of a spring-biased system acting on one or both of the facing conveyer runs.
