Abstract:
A flexible conveyor belt is provided which can run in a curved shape which elongates along a lower inner wall of a circular pipe, while being completely supported above the lower inner wall by pressurized air introduced into a space between the belt and the lower inner wall. In the case where the flexible conveyor belt is mainly made of rubber, a trough index T (JIS K6322) which is obtained as a ratio of a deflection amount F to a width x of the belt is equal to or greater than 0.35. More strictly, it is preferable to set the thickness y (mm) and the width x (mm) of the belt to satisfy the relationship of y.ltoreq.0.143+6.486.times.10.sup.-3 x+7.904.times.10.sup.-6 x.sup.2. In the case where the flexible conveyor belt is made mainly of a resin, the trough index is equal to or greater than 0.30. The conveyor belts have sufficient flexibility.
Abstract:
A pivoting transfer means for a jet of bulk material between a first cover belt conveyor and a second cover belt conveyor. The bulk material leaves the cover belt conveyor in the area of the tail pulleys and enters the receiving mouth of a second cover belt conveyor as a free jet of bulk material. Both cover belt conveyors are arranged pivotably in relation to one another around a pivot axis. The receiving mouth of the cover belt conveyor is limited by the bottom belt, the cover belt and the side walls. The jet of bulk material is deflected from the vertical into the horizontal direction of delivery within the receiving mouth. The first belt conveyor may be arranged at a higher level with the second cover belt conveyor arranged thereunder. However, the second cover belt conveyor may also be arranged at a higher level with the first cover belt conveyor arranged thereunder wherein the transfer is still from the first cover belt conveyor to the second cover belt conveyor.
Abstract:
The invention concerns a bucket conveyor in which the outer and inner links (5, 6) of the sprocket chain are connected to the buckets (1) by connector bars (2) and bushings (7, 9) which are inserted into the outer links and which, in addition, enclose the ends of link pins (10) that carry the inner links (6) via a common bushing (8) associated with them.
Abstract:
A stabilizer unit for material on a moving conveyer surface comprises a framework mounted over the surface with a drive pulley making driving engagement therewith. A drum is rotatably supported in the framework and carries a stabilizer surface thereon. The drive pulley is coupled to the drum to rotate the drum with its peripheral velocity substantially equal to that of the drive pulley, thus imparting the corresponding velocity to the stabilizer surface. The stabilizer surface can be a belt loosely carried on the drum, which follows a path with a first section overlaying the conveyer surface, a second section in engagement with a segment of the drum surface, and third and fourth sections extending between the drum surface and the respective points of separation of the stabilizer belt from the conveyer surface. Movement of the conveyer surface rotates the drive pulley and thereby the drum to advance the stabilizer belt around its path at a speed equal to the speed of the conveyer surface. With no substantial relative movement therebetween, the stabilizer belt and the conveyer surface stabilize material held therebetween along the first section of the stabilizer belt path.
Abstract:
A materials carrying apparatus and method is provided. The apparatus includes a frame. A first carrier is supported within the frame for carrying materials thereon. The first carrier is located in an access position for access to and use of the materials by a user. A second carrier is supported within the frame and located in a storage position for carrying materials thereon. The storage position is vertically spaced apart from the access position. An elevator assembly vertically moves the second carrier from the storage position into the access position when the materials of the first carrier have been exhausted.
Abstract:
A steel wire or cable conveyor belt with improved penetration and rip resistance is made by plying up a series of rubberized longitudinal steel cables or wires to give a core, placing a ply of rubberized woven fabric such as polyaramide or nylon over the core, such as a tire breaker ply or plies over the core, then a ply of rubberized closely placed, essentially in contact wire, preferably of heavy tire ply cable, such as an earth mover ply, cut to cover the core in transverse direction to allow the steel wire or cable to be positioned perpendicular over the longitudinal steel wire or cable, apply a cover stock ply over the transversely positioned short wire or cable. The underside of the longitudinal steel wire or cable core has a rubberized woven fabric positioned there beneath and a rubberized pulley ply beneath the woven fabric ply. The plied up belt is cured with pressure and heat to adhere the plies together and cure the rubber. The usual belt cure pressure of 200 to 500 psi and temperatures of about 140.degree. C. to about 160.degree. C. for about 30 to about 90 minutes can be used, depending on the curative.
Abstract:
A chain or series of trolleys having horizontal axles is supported in an upwardly opening track. A pendant has an incurved bearing surface that rests on one of the axles. A bent support arm is secured to an upwardly extending post of the pendant and supports a load. The pendant is pivotable on the axle to maintain the post in a generally vertical attitude. An arcuate slot in the pendant receives a transverse pin on the chain to prevent inadvertent vertical movement of the pendant. The pendant is removed from the axle by tilting the pendant and lifting the pendant from the axle.
Abstract:
A conveyor system is set forth that includes a track having a generally linear section and a generally curved section. The track further includes a guide channel having sidewalls that engage a guide member that is in fixed positional alignment, for example, with a carrier and/or belt. The guide member engages the sidewalls of the guide channel to facilitate guided movement of the carrier and/or belt along the track. The guide member includes a linear portion that is engaged by the track when the guide member is disposed along the linear section of the track while being generally disengaged from the track when the guide member is disposed along the curved section of the track. The guide member further includes a curved section that engages the sidewalls of the guide channel when the guide member is disposed along the curved section of the track. The radius of curvature of the curved portion of the guide member generally coincides with the radius of curvature of the track about a curved portion of the track.
Abstract:
An impact pillow for resiliently supporting a conveyor belt in an impact zone in a conveyor transfer point. The impact pillow includes a base wall, first and second side walls each extending upwardly from said base wall to a top edge, and first and second end walls each extending upwardly from said base to a top edge and between said side walls. A top wall extends from and between the top edges of the side walls and the end walls forming a support surface over which the conveyor belt slides. The top wall, base wall, end walls and side walls combine to form an integral shell having a closed cushioning chamber adapted to receive and contain a cushioning substance. The cushioning substance may be a gas, a fluid or a resilient solid material. The impact pillow resiliently supports the moving conveyor belt as material is loaded onto the conveyor belt at the transfer point and absorbs the impact forces generated on the conveyor belt during the loading process. Different types of cushioning substances may be utilized in the cushioning chamber to selectively adjust the resistance of the impact pillow to deformations from the impact forces.
