A wear detection device for a conveyor belt () includes magnet members (and) buried in a conveyor belt () having an endless belt shape, a magnetic sensor () which is arranged opposite to an outer circumferential surface of the conveyor belt () and is configured to detect magnetic fields from the magnet members (and) to generate an output signal, and a calculation unit () which is configured to calculate the thickness of the conveyor belt () according to the output signal generated by the magnetic sensor (). The wear detection device for a conveyor belt () further includes a storage unit () which is configured to store the thickness calculated by the calculation unit (), and a processing unit () which is configured to calculate the decrease amount of the thickness per a predetermined moving load amount of the conveyor belt () according to the thickness stored in the storage unit () and determine whether or not this value exceeds a threshold value set in advance.

Wear detection device for conveyor belt

A manufacturing method of a finite conveyor belt of the present invention includes a laminated body formation step of forming a laminated body () in which a core layer member () which includes a tensile body () is interposed between an unvulcanized top cover rubber member () and an unvulcanized bottom cover rubber member () in a belt thickness direction T, and a vulcanization step of vulcanizing the laminated body () by pressurizing in the belt thickness direction (T) and heating the laminated body to form a finite conveyor belt, and the laminated body formation step includes a member formation step of forming the top cover rubber member () by separately connecting both ends of an unvulcanized first cover rubber part () in a belt length direction (L) in which a detection object () is embedded with ends of an unvulcanized second cover rubber parts () in the belt length direction (L).

Manufacturing method of finite conveyor belt, joining method of finite conveyor belt, manufacturing method of endless conveyor belt, and conveyor belt apparatus

A sensor and monitoring system that can prevent the accumulation of scraps of a transport object on the sensor are provided. A sensoris located below a return-side portionof a conveyor belt, and includes: a detectorthat detects a detection objectembedded in the conveyor belt; and a covercovering at least an upper part of the detector, wherein the cover has a downward surfacethat extends continuously downward from a top part of the cover while extending outward in the horizontal direction.

Sensor, and monitoring system

A conveyor belt apparatus () is provided with a wear measuring device () that measures an amount of wear of a surface () of a conveyor belt () on which transport material has been loaded, and with a revolution counting device () that counts a number of revolutions of the conveyor belt ().

Conveyor belt apparatus

A rubber magnet () includes a plate-like diagonal portion () and a plate-like parallel portion () which are both magnetized in a thickness direction, the diagonal portion () extending in a conveyor belt width direction while linearly extending, in section in a conveyor belt length direction, from an outer side end (), which is closer to the front-side surface (), to an inner side end (), which is away from the front-side surface (), while being at an angle to the front-side surface (), the parallel portion () being formed continuously from the inner side end () of the diagonal portion, so as to be arranged parallel to the front-side surface ().

Conveyor belt wear detection apparatus

To provide a thermoplastic resin container that contains food or drink subjected to a retort processing for which completion of the retort processing can be confirmed and supervised with simple means without the need of an expensive member or facility, not only whether the temperature of the retort processing is reached but also whether the retort processing is performed as specified can be confirmed, and the consumer also can easily confirm completion of the retort processing of the product. The container is produced by two-stage stretch blow molding of a preform made of a thermoplastic resin in such a manner a part that is not stretched or is insufficiently stretched is formed at a part of the container, and the part that is not stretched or is insufficiently stretched is whitened to form a retort processing completion confirming part by heating in the retort processing after a content is packed and sealed in the container.

Thermoplastic resin container for which completion of retort processing can be confirmed and method for producing the same

A polyester container obtained by stretch-forming a preform of a thermoplastic polyester resin formed by injection forming wherein the central portion of the bottom wall is the remaining part of the gate at the time of injection forming, and is formed relatively thicker than the bottom wall surrounding the central portion, and the central portion of the bottom wall is substantially amorphous, and the bottom wall surrounding the central portion is oriented and crystallized. The container exhibits excellent heat resistance and shock resistance despite a thick portion that is the remaining portion of the injection gate is formed at the center of the bottom portion.

Polyester container having excellent heat resistance and shock resistance and method of producing the same

In a plastic container manufactured by melting blow molding a heated and molten parison extruded from an extruder, a mouthand/or a specified part of a bodyhas a thicker thickness than the body proper. One or more thick parts of the bodyare continuously or discontinuously formed over part or all a peripheral, height or helical direction of the body of the container. The container enjoys enhanced rigidity, appearance and functionality even when the thickness of its body is considerably reduced.
