A conveyor belt includes a core layer disposed between an upper cover rubber layer and a lower cover rubber layer. The core layer is configured from a plurality of steel cords covered by cushioning rubber and arranged in parallel. The rubber that forms the lower cover rubber layer is a low loss rubber that has a loss factor tanδ of 0.07 or less at a frequency of 10 Hz, 2% dynamic strain, and temperature of 20° C. The maximum thickness of the cushioning rubber is reduced to not more than ⅓ the nominal diameter of the steel cords.

A conveyor belt has one or more conveyor belt segments made of an elastomeric material layer and a reinforcement layer of steel ropes disposed in the elastomeric material layer and oriented in a longitudinal direction of the conveyor belt segment. The conveyor belt segments each have a first segment end provided with a first transverse lock bar and a second segment end provided with a second transverse lock bar, wherein ends of the steel ropes are locked frictionally or with form fit in the first and second transverse lock bars, respectively. One or more detachable closure members couple the first and second transverse lock bars of a single one or of adjacently positioned ones of the conveyor belt segments to each other in a rigid correlation relative to each other.

A splicing device (10) for closing a looped material band (1) comprising two splicing elements (20, 30) intimately linked to the ends (2, 3) of the material band (1), assembled together by fitting two toothings (22, 23) into each other, and locked by a transverse locking rod (15) inserted in the aligned transverse openings (14) of the teeth (13) of each toothing. The splicing elements (20, 30) are made out of a material compatible with that of the material band and comprise a traction core extending longitudinally up to the teeth (13) and surrounding the transverse opening (14) of teeth (13) of each toothing (22, 32) so that, when the splicing device (10) is assembled and locked, the traction cores of the splicing elements ensure the tensile strength of the splicing device (10) while remaining very flexible.

A conveyor has a belt arranged to be urged around conveyor rollers, and a belt cover formed of an endless loop of fabric material and is in frictional communication over the belt. The belt cover is formed of two plies that are arranged to be adhered to one another in an edge region of the belt cover. The communication between the belt cover and the belt has a coefficient of friction of ˜0.50. A message is printed on the outer ply of the belt cover. In addition, an antimicrobial material is disposed on the belt cover, and is formed of silver nanoparticles embedded in a polyurethane film having a thickness of ˜0.5 mil.
摘要:
The present invention relates to conveyor belts having rip detection systems which utilize microcoil sensor wires which offer improved durability as compared to conventional microcoil sensor wires. This higher degree of durability increases service life of the rip detection system and allows for the conveyor belt to be used reliably over an extended time period without the need to replace damaged microcoil sensor wires within the rip detection system of the conveyor belt. The present invention more specifically discloses a conveyor belt comprising (1) an elastomeric body having a load carrying surface and a parallel pulley engaging surface; (2) a reinforcement ply disposed within the elastomeric body; and (3) a rip detection sensor in the form of a microcoil sensor wire which is configured in an endless loop, wherein the microcoil sensor wire is comprised of an elastomeric core having an electrically conductive wire spirally wrapped around the elastomeric core.

The invention is directed to an apparatus for continuous and non-destructive monitoring of the connection of a conveyor belt. During movement of the conveyor belt, a radiation source emits rays in the direction of the belt surface. The rays are of such high energy that they penetrate the conveyor belt and the connection thereof within a material-free region. A sensor detects the rays which have passed through. A process computer evaluates the result of the radiographic examination by comparing the actual connection values to set connection values and connection limit values. The radiation source and the sensor are accommodated in a housing. The housing has two openings between the radiation source and the sensor through which the moving conveyor belt passes without contact. The housing is integrated into the lower run of a conveyor system.
摘要:
An arrangement continuously and non-destructively monitors a conveyor system having a continuous conveyor belt with a carrying-side cover plate and a running-side cover plate, each made of a polymeric material with elastic properties. The arrangement further includes drums wherein the above-mentioned components form, in conjunction with the conveyor belt, a material-conveying top strand (A) and a material-conveying or material-free bottom strand (B). A conductor loop packet with continuous conductor loops is embedded in the conveyor belt. An electronic slit protection system contactlessly detects damage to the conveyor belt. The slit protection system is an electrical system including an interrogation station and a slit monitoring station and is connected to a central controller which controls the entire conveyor system. The arrangement is equipped, as part of a conductor loop packet, with sequential conductor loops and a sequential slit protection system.
摘要:
A mat for the transport of an object on a top surface of the mat is disclosed. The mat comprises elastic material, and reinforcements are provided in the mat that are enclosed at least partially by the elastic material. The reinforcements are aligned parallel or approximately parallel to one another, and the elastic material and the reinforcements interact in such a way that a flexing of the mat at a first arc of curvature in a first plane can take place with less force than at a second arc of curvature in a second plane. A transfer device for at least one object in combination with the mat is also disclosed, whereby the transfer device comprises means for moving a mat and means for guiding the mat out of a transport plane. Methods for transferring an object are also disclosed.
