Abstract:
A balanced flat stroke bi-directional conveyor for conveying object, granular and powder material. The unit utilizes the skewed sine wave trough stroke principle using primary eccentric counterweights wheels driven by a motor running at the secondary speed and equipped with the secondary eccentric counterweight wheels and a third counterweight wheel. The forces not in line with the trough stroke are absorbed with an isolation spring mounted between the drive assembly and the base, while the forces in line with the trough are balanced via a connected balancer.
Abstract:
A container transport system for transport of an article, in particular a baggage item, includes a container for receiving an article, with the container made of flame-resistant, wear-resistant and translucent plastic material which is stable in shape. The container has an underside which is formed with touch surfaces extending in a transport direction by which the container is advanced by a conveyor between a receiving end and a discharge end. The conveyor is provided with a guiding and/or driving engagement assembly for cooperation with the touch surfaces of the container.
Abstract:
A conveyor system for transport of containers, in particular an airport baggage handling system, includes a conveyor having a curved transport path with one end defining an entry zone and another end defining an exit zone. The containers are moved by a container propulsion mechanism along the curved transport path between the entry and exit zones, wherein the curved transport path is constructed for movement of the containers in an inwardly inclined disposition for reducing centrifugal forces.
Abstract:
A joining line from a portion of a belt caught and held between a driving roller and a pinch roller and the vicinity thereof to an outer peripheral end of the belt is a single straight line or a gentle curve having a large angle with respect to a tangent to a belt peripheral line. The joint of the other part of the belt is made by a finger joint. Alternately, a joining part from a portion of a belt caught and hold between a driving roller and a pinch roller and the vicinity thereof to an outer peripheral end of the belt is made with a finger joint with widely pitched fingers, while another joining part of the rest of the belt are made with a finger joint with narrowly pitched fingers. Peeling or breakage at the joining parts for a long time, and a thick joining part are eliminated. And low cost production is achieved.
Abstract:
In a curved conveyor with end rollers disposed at a certain angle between which a belt body is stretched, a plurality of bead constituting elements is detachably disposed along the outer peripheral end of the belt body. Alternatively, in a linear conveyor with end rollers disposed in parallel between which a conveyor belt body is stretched, a plurality of bead constituting elements is detachably disposed along both ends of the belt body. In these conveyor belts, only damaged bead constituting elements may be readily replaced.
Abstract:
The beads of a beaded conveyor belt for a curve conveyor are constituted by a number of bead constituting bodies (2b) that are disposed over the entire periphery of the outer surface along the outer peripheral edge of a belt main body (2a) and that are narrow in the direction of the length of the belt. Further, the beads of a beaded conveyor belt for a liner conveyor are constituted by a number of bead constituting bodies (7b) that are disposed over the entire periphery of the outer surface along opposite side edge of a belt main body (7a) and that are narrow in the direction of the length of the belt. The conveyor belt is installed taut between straight type end rollers (15), and the width of the bead constituting bodies (2b, 7b) lengthwise of the belt is set at about 20-60% of the diameter of the straight type end rollers (15). Even when the conveyor belt is installed taut between small-diameter end rollers, long-term use is possible.
Abstract:
The invention relates to a device for monitoring a tubular belt conveyor system, comprising the following: a conveyor belt consisting of an elastomeric material, especially with embedded tie rods, the conveyor belt being closed to form a tubular belt by overlapping its longitudinal edges so as to form an overlap area; other system parts, i.e., a driving drum, a tail pulley, support rollers, guide rollers, supporting structures and optionally, other parts. The inventive device is characterized in that the device for monitoring the overlap area of the tubular belt is provided with an optoelectronic system. In the event of a deviation from the desired conveyor belt overlap, the optoelectronic system initiates a correction of position by means of the guiding rollers. If the corrective measures are not taken within a certain period, the tubular belt conveyor system is automatically disconnected.
Abstract:
A belt conveyor comprises an endless and closed conveyor belt (25) which is flexible essentially merely about axes which are parallel with the transverse direction of the belt (25), a tower (2; 70, 75); an inner arm (3; 64) supported by the tower (2; 70, 75); and an outer arm (6; 66) supported by the inner arm (3; 64) and positioned substantially in a vertical plane through the inner arm (3; 64). The conveyor belt (25) follows a path from the tower (2; 70; 75), via the inner arm (3; 64) and the outer arm (6; 66) to a distal end of the outer arm (6; 66) and back via the outer arm (6; 66) and the inner arm (3; 64) to the tower (2; 70; 75). Two first deflection rollers (10, 11; 65, 68) for the conveyor belt (25) are supported side by side at an intersection of the inner arm (3; 64) and the outer arm (6; 66) and has a common axis of rotation (12, 13) which is perpendicular to said vertical plane. A first terminal roller (8; 67) for the conveyor belt (25) is supported at a distal end (20) of the outer arm (6; 66) and has an axis of rotation (19), which is positioned in said vertical plane.
Abstract:
A belt conveyor comprising an endless, fixed-width belt mounted on a pulley provided on rollers. Protrusions are formed on the back surface of the endless, fixed-width belt, and each of the protrusions has a shape comprising inwardly curved front and rear sides and tapering towards its tip end, and the pulley that is detachably mounted to each of the rollers is formed with holes, and each of the holes has a shape that fits each of the protrusions of the belt. The protrusions of the belt snugly engage with holes of the pulley, thus preventing meandering of the rotating belt.
Abstract:
Conveyer belts (10) are deflected many times along a conveying path of the objects to be conveyed. It has been shown that unpleasant squeaking noises are generated in the region of this deflection between the guide means (12) of the conveyer belt (10) and guide rollers or guide drums. The invention is based on the knowledge that the squeaking noises are caused by the relatively high friction value of the material of the conveyer belt (10). The design according to the invention therefore proposes that at least the outer side of the guide means (12) of the conveyer belt (10) is provided with a coating (26) made from a material with a lower frictional value. As a result, it has been shown that undesirable squeaking noices can be effectively avoided.
