摘要： An apparatus for sensing an obstruction within a tube being cleaned and repetitively advancing and retracting a flexible high pressure fluid cleaning lance within the tube is disclosed. The apparatus monitors drive roller/belt position and actual hose position, compares the belt (expected travel) to hose position (travel) and generates a position difference, or mismatch. If the mismatch is above a predetermined level, the drive motor direction is reversed for a predetermined time interval, and forward operation restored after the predetermined time interval; and the sequence of repeating the reversing and restoring operations is continued until the position difference or mismatch no longer exceeds the predetermined difference threshold.

摘要： In one example, a method of controlling a printing system is described, the method comprising activating a driver to advance a conveyor belt in a plurality of sub-turns. For each of the plurality of sub-turns, a first parameter associated with movement of the conveyor belt is determined, based on data obtained from the driver. For each of the plurality of sub-turns, a second parameter associated with movement of the conveyor belt is also determined, based on data obtained from an optical sensor. A per-sub-turn slippage parameter is calculated for each of the plurality of sub-turns, based on any difference between the first parameter and the second parameter. The method further comprises calculating a slippage metric based on the per-sub-turn slippage parameters for the plurality of sub-turns, and causing outputting of a conveyor belt tension adjustment indication.

摘要： A system and a method is disclosed for monitoring tension and detecting slip of industrial belts (e.g. V, flat, and Timing belts) while in running condition on belt drives by using ultrasonic transducers. The sensing part involves two ultrasonic transducers which are installed on an assembly which is placed within a constrained space between the tension side and slack side of belt. Acoustic waves having predefined amplitude are sent from transmitting transducer on the belt and amplitude of the signal reflected from the belt is measured and compared with a threshold value to detect reduced tension. Additionally, acoustic plugs are mounted on driver and driven pulley locknuts to blank the reflected signal periodically. The time period of the blanking of signals from the pulleys is computed and it measures the rotational speed (revolutions per minute: rpm) of the pulleys. This rpm is used to calculate the rotational speeds of the pulleys. The rotational speeds of the driver and driven pulleys are compared with respect to the theoretical speeds inversely proportional to the diameters of the pulleys to detect the slip of the belt. The apparatus generates an alert to user when the belt tension is reduced and/or when slip is detected. The processing circuit involves a microcontroller with Wi-Fi module to send the alert messages to remote location such as cloud and/or to user interface devices such as computers or mobile phones.

摘要： A system and an apparatus capable of independently driving movers are described herein. The system and apparatus includes: a track that forms a path for movers; a plurality of movers movably mounted on the track for moving along the path; and a plurality of drive elements fixedly arranged along the track. The drive elements each have a surface that is oriented to contact a driven member of the movers. The drive elements are configured to sequentially engage the driven member of a plurality of the movers to provide controlled independent motion of the movers along the track. The drive elements may be driven by rotary motors. A method of independently driving movers is also described herein.

摘要： A misaligned belt sensing apparatus determines when a conveyor belt becomes misaligned, indicating repair or replacement are required. At least one sensing apparatus is placed nearly in contact with the belt which produces heat due to friction between the belt and the apparatus when it comes in contact with same due to misalignment. The sensed temperature is compared to threshold values and indicates when the conveyor belt has become misaligned, as well as determining operational wear status of the sensing apparatus after a number of such misalignments. Each heat sensing apparatus comprises at least one thermally conductive plate where a moving misaligned belt rubs against the thermally conductive plate and generates heat due to friction between the moving belt and the thermally conductive plate, where each plate has one or more independent temperature sensing elements for misalignment detection and indication, also detecting wear status of the plates of the apparatus.

摘要： To synchronize the belt of a conveyor, a scanner, a fluorescent lamp, and an LED display unit of an area meter, the main AC power supply of the area meter drives the conveyor belt through a synchronous motor and supplies the same frequency of power to a phase locked loop. The phase locked loop provides synchronous pulses of higher frequencies to the scanning system, fluorescent lamp and LED display unit to maintain synchronism. The resolution of the measuring system is optimized when changes are made in the size of the area that is scanned by adjusting: (1) the lens of the scanner; (2) the rate of readout of the pulses from the scanner; and (3) the decimal place of the display unit. Travel from side to side of the belt is avoided by individually adjusting the ends of the pulleys until the belt runs true and an idler which lifts both bottom and top run of the belt when an object moves under it prevents slippage of the belt with respect to the rollers and the bite of the conveyor is adjustable.
