An inspection device for inspecting a bunch yarn winding wound on a take up tube of a package. A black light is provided for irradiating the bunch yarn winding with light having a wavelength substantially in the ultra violet range, and a CCD camera is provided for sensing and inspecting the irradiated bunch yarn winding.

Bunch yarn inspection method and device

A package inspection apparatus comprising a tray having a peg inclined for mounting a package thereon, a conveyor having a pair of chains for carrying the tray, an inspection box mounted on the conveyor, a light source and a camera mounted in the inspection box for inspecting for bunch winding and bulge winding of the package, and a package weight measuring instrument vertically movably mounted between the chains.

Package inspection apparatus

A package inspecting apparatus comprising a yarn end processing section for exerting suction air on the surfaces of packages while rotating trays on a running passage for trays on which packages are fitted, a package inspecting section in which a plurality of optical type package winding-form inspecting devices are received in a dark room, and a weighing section provided with a weight measuring unit, said sections being arranged in series in said order and integrated.

Package readying and inspection apparatus

A package inspecting apparatus including a yarn end processing section for exerting suction air on the surfaces of packages while rotating trays on a running passage for trays on which packages are fitted, a package inspecting section in which a plurality of optical type package winding-form inspection devices are received in a dark room, and a weighing section provided with a weight measuring unit, the sections being arranged in series in the above order are integrated.

Yarn package inspecting apparatus

In a spinning mill in which a bobbin from a spinning frame is mounted on a bobbin tray and sent to a winder, a package doffed from the winder is loaded on a hanger and then the package is mounted on a package tray, recording media is provided on the bobbin tray, on the hanger and the package tray, respectively. Frame numbers and spindle numbers which are production origin information of bobbins are written on the recording medium so that the production origin information can be controlled and the records can be grasped.

Production control system in spinning mill

In a cobwebbing detection device of the type in which light illuminates the end surface of a package and a cobwebbed yarn is detected by photographing the end surface by a CCD camera, a cobwebbing detection device has a binary encoder which converts each pixel of the image data into a binary coded data, a storage device, for storing the binary-coded pixel data, and a detection circuit which detects each pixel [1] or [0] in each scanning.

Cobwebbing detection device

A ray having an optical axis approximately parallel with a surface of a yarn layer is irradiated against a surface of a package, and a light receiving element for receiving light reflected on an abnormal yarn on the surface of the yarn layer is provided at a position at which the reflected light is maximum to detect an abnormal yarn.

Method for detecting an abnormal portion of a yarn package

An apparatus for finding an end of a yarn of a spinning bobbin comprising a cutter mechanism located adjacent a path along which a spinning bobbin fitted uprightly on a tray is fed for releasing and cutting a bunch of a yarn on the bobbin, a yarn end pick-up mechanism located next to the cutter mechanism for picking up an end of the out yarn from a layer of the yarn, and a yarn end inserting mechanism located next to the yarn end pick-up mechanism for cutting the yarn end picked up frm the yarn layer into a string of a particular length and for inserting the yarn into a center hole of the bobbin.
