A parts feeder for feeding a plurality of parts along an annular conveyance path and a linear conveyance path connected to the annular conveyance path comprises an adjustment device which is provided midway along the annular conveyance path and which adjusts the parts, and a fill detector which is provided midway along the linear conveyance path and which detects filling of the linear conveyance path with the parts and generates a fill signal in order to stop parts feed to the linear conveyance path when the linear conveyance path is filled with the parts. A compressed air feeder is located in the vicinity of the adjustment device. The compressed air feeder blows compressed air against at least the parts located at the adjustment device in order to remove the parts from the adjustment device while the parts feed to the linear conveyance path is being stopped.

Parts feeder

A tape winding device in which magnetic tape is wound onto a reel. One or more magnets exert a magnetic force on the wound tape in a direction along the thickness of the tape, that is, along a diameter of the reel, in order to neatly wind the tape. The magnets may be movable radially to maximize the magnetic force or be moved axially to control the axial position of the tape independently of the reel flanges.

Method and device for winding magnetic tape using magnetic alignment

In a magnetic tape winding system, an end portion of a magnetic tape, which is cut after the magnetic tape is wound by a predetermined length from a magnetic tape feed roll to a first small wind-up frame, is joined with one end portion of a leader tape having the other end portion engaged with a second small wind-up frame by use of a joining tape. Immediately after the joining, the magnetic tape and the leader tape joined by the joining tape is rewound by a predetermined length around the second small wind-up frame, whereby slack of the tape between the first small wind-up frame and the second small wind-up frame is eliminated without causing the joining section of the magnetic tape with the leader tape to contact the magnetic tape surface at the outermost circumference of the magnetic tape roll wound around the first small wind-up frame.

Magnetic tape winding method and apparatus

A magnetic tape winding method and apparatus in which a magnetic field is applied to a magnetic tape during winding on a reel to even up the edges of the wound tape. After winding, the magnetic tape is demagnetized.

A tape winding method and apparatus in which two sets of magnets disposed at different places around the take-up reel of a magnetic tape apply a magnetic field in the width direction of the tape at one position and in the thickness direction at another position. Thereby, the tape is both radially compressed and evened to one side.
