摘要:
A bobbin sorting device including a color sensor for distinguishing trays on which different kinds of bobbins are conveyed, characterized in that a metal plate is attached to each tray having one of different colors, and a detector is provided near the color sensor for detecting the metal plate.
摘要:
A device for finding an end of a yarn whereby an end of a yarn connecting to a layer of the yarn on a bobbin is found and is inserted into a center hole of a bobbin. The device includes an air flow controlling plate located near an outer periphery of a layer of a yarn on a spinning bobbin and a compressed air injection nozzle located in a gap between the air flow controlling plate and the yarn layer of the spinning bobbin.
摘要:
A spinning frame management method comprising putting an identification mark on a tray for conveying a spinning bobbin produced by each spinning unit of a spinning frame to a winding unit of a winder, reading the identification mark in transferring the spinning bobbins from the spinning unit to the tray and storing the spinning unit which produced the same bobbin, detecting defects in the yarn of the spinning bobbin in rewinding the yarn of the bobbin and reading the identification mark put on the tray mounted with the same bobbin, and inquiring into the defects of a particular spinning unit by using the stored information.
摘要:
A steam setting system for steam setting a plurality of bobbins reduced by a fine spinning frame in which a steam setting apparatus comprising at least a pair of independent steam setting mechanisms is provided on the way of a bobbin feeder line connecting a fine spinning frame with a winder.
摘要:
To provide a tension control system in a false twist texturing machine for producing a doubled yarn wherein the target tension values or allowable ranges of filament yarns y1 and y2 prior to doubling can be individually set for each filament yarn and wherein based on the results of the detection of the tension of the filament yarn prior to doubling, each false twister T for the corresponding filament yarn is individually and independently controlled in such a way that the tension of each filament yarn has the set target tension value or falls within the set allowable tension range. A target tension value and an allowable tension range can be individually set for each filament yarn prior to doubling so as to accommodate the yarn's material, thickness, and structure, and the false twister can be individually and independently controlled based on the results of the detection of the tension of each filament yarn prior to doubling. Consequently, higher-quality doubled false twist texturing yarns can be manufactured.
摘要:
There is provided a process for inspecting a splicer provided for splicing yarn ends upon the occurrence of yarn breakage or the like in an automatic winder, the process comprising the steps of, after splicing yarn ends, taking up the spliced yarn at a low speed and restraining the yarn on the yarn supply side to impart a predetermined tension to the yarn, detecting whether yarn breakage indicative of malfunction of the splicer has occurred, and, if the yarn breakage indicative of malfunction of the splicer has not occurred, cutting the spliced yarn, and re-splicing the yarn ends of the yarn thus cut.
摘要:
A method of changing bobbins in lot for an automatic winder comprises the steps of hindering fully wound winding units from further winding yarns when an amount of a residual yarn supply becomes smaller than a predetermined value, and discharging bobbins with residual yarn from the fully wound winding units to deliver the same to the other winding units being in winding operation.
摘要:
In a spinning winder wherein a winder and a spinning machine are connected by a bobbin transporting passage, spinning bobbins are alternately supplied from R side and L side transport bands of the spinning machine to a bobbin supplying station disposed between the winder and the spinning machine according to a spinning bobbin demand signal.
摘要:
A false twister which nips a yarn-between crossed belts and impart twist and feed to the yarn includes a sensor for detecting an untwisting tension of the yarn portion located downstream of the belts and the untwisting tension detected by the sensor is controlled to a target value of an untwisting tension by adjusting a contact pressure between the belts or a running speed of the belts.
摘要:
In the winding position of each winding unit there is provided a bobbin dislodgement preventing device adapted to come into abutment with part of a bobbin which is fed to the winding position as it is fitted upright on a tray with peg to thereby prevent the bobbin from coming off the peg.
