    Abstract: A conveyor belt for use in a tubular conveyor belt system has a width and a length, and a longitudinal centerline. The conveyor belt further has a first longitudinal edge, and an opposing second longitudinal edge, wherein during use, the first longitudinal edge and the second longitudinal edge overlap to form an overlap region, thus forming the belt into a tube-like shape. The conveyor belt further has a load bearing region, wherein the load bearing region is located evenly about the belt longitudinal centerline, throughout the length of the belt. Further, there is a first anti-rotation region and a second anti-rotation region, wherein the first anti-rotation region is located between the first longitudinal edge and the load bearing region, and the second anti-rotation region is located between the second longitudinal edge and the load bearing region.

  • Publication number: 20090038911
    Abstract: To provide a pipe conveyer in which a twist or depression of a rounded conveyer belt is simply and efficiently detected by effectively using permanent magnets and the closability of the conveyer belt is improved. [MEANS FOR SOLVING PROBLEMS] A conveyer belt (3) is rounded into a pipe, and both side edges (3a, 3b) of the conveyer belt (3) are laid on one the other. On both opposed surfaces of the edges, permanent magnets (6, 7) attaching each other are provided. A fixed body through which the rounded conveyer belt (3) passes is provided, and a plurality of magnetic sensors (8) are so circumferentially arranged on the fixed body as to surround the conveyer belt (3) and to detect the magnetic force strengths when the permanent magnets (6, 7) pass by the fixed body. Twist detecting means (11) for comparing the detected magnetic force strengths and detecting a twist of the conveyer belt (3) from the position of the magnetic sensor (8) which has detected the peak value (P1) is provided.

  • Patent number: 7344016
    Abstract: A method and device are disclosed for orienting flat items of mail towards a narrow edge in a U-shaped conveying channel in which they are conveyed in an upright position and without being jammed. Before the items pass the conveying channel for the purpose of alignment, their thickness is measured. The distances of the lateral limit stops or limiting sections are changed by means of adjusting mechanisms for every item of mail in such a manner that at the end of the conveying channel, the item is oriented towards its lower narrow edge by virtue of its own gravity and the distance of the lateral limit stops of the conveying channel from every item of mail during transport through the conveying channel is only wide enough for the item not to collapse at all nor to collapse partially even if its intrinsic stiffness is poor.

  • Patent number: 7261203
    Abstract: A prestressed tubular belt has variable prestressing forces located along its width to provide control overt the shape of the belt, while at the same time providing the proper forces in order to maintain the integrity of the belt shape. Various methods and systems are utilized in the manufacturing of such a tubular belt. One such methods involves stretching and affixing one portion of a belt layer to a non-stretched layer in a stepwise manner. Another system and appertaining method involves utilizing anchor strips affixed to a layer of the belt and then stretching the belt in a stepwise manner using ribs on a tool that mate with the anchor strips to hold the layer in varying degrees of tension prior to affixing a second layer to it. Other mechanisms for applying variable prestressing forces are also considered.

  • Patent number: 6991093
    Abstract: This invention relates to an endless fold-over type of conveyor belt for use in conveying relatively-loose bulk material in an enclosed manner to prevent spillage, dusting and contamination of the material and allows the belt to operate at steep angles. The belt comprises essentially a rectangular uniform cross-sectional shape having a substantially greater width than thickness. Two similar arrays of longitudinal grooves are located on the side of the belt opposite to that carrying the load, the grooves being spaced on both sides of the belt medial portion to provide a pair of hinged areas for folding and unfolding the belt. The longitudinal grooves preferably are V-shaped or U-shaped and between one and five grooves may be provided in each array at about one-quarter the belt width from its edges to provide a pair of overlapping edge flaps to cover the medial area when in folded relation.

  • Patent number: 6702103
    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.

  • Patent number: 6685006
    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.
