Wire winding is performed while a guide member is regulating a winding position of a regular-square wire (for example, while moving the wire member in an axial direction in accordance with the number of winding (turns) of the rectangular cross section wire member) such that a side surface of the regular-square wire already wound on an outer periphery of a cylindrical part of a bobbin closely adheres to a side surface of the regular-square wire about to be wound. Thus, it is possible to form a coil having an excellent characteristic by winding the regular-square wire on the without making a gap.

Winding device for wire material with rectangular section

A taping technology capable of restraining an ill-wound state of a tape is disclosed. Chucking members of a leading chuck and chucking members of a trailing chuck have widths narrow enough to enter between flange members of a bobbin, and are therefore capable of grasping leading and trailing ends of the tape till the chucking members get close to a wire member wound on a cylindrical member, whereby disordered states at the leading and trailing ends of the tape can be restrained as much as possible and an ill-wound state of the tape can be therefore restrained.

Taping device and taping method

A taping method and apparatus for performing at least one taping operation. Each taping operation is performed by adhering an extra length of adhering allowance of a tape to an outer surface of a coil having a coil bobbin rotatably supported by a spindle. A tape retaining means is used to retain the tape against a tape rolling means while a foremost end of the tape is projected, by a distance corresponding to the extra length of adhering allowance, ahead of a retaining position defined by the tape retaining means. The distance between the spindle and the tape rolling means is shortened until they come into contact thereby causing the extra length of adhering allowance to adhere to the outer surface of the coil. Thereafter, the tape is wound about the coil by rotating the spindle, and a tape cutting means is displaced to cut the tape while the tape is retained between the tape retaining means and the coil bobbin and such that a subsequent extra length of adhering allowance of the tape does not enter a region defined by the tape retaining means. Any tape remaining on the coil is then wound by rotating the spindle. The coil bobbin is retractively displaced in an upward direction, and the tape is projected ahead of the retaining position of the tape retaining means by a distance corresponding to the extra length of adhering allowance. The above steps are repeated until all taping operations are completed.

Taping method and apparatus

An automatic coil winding and finishing machine. First and second bobbin conveying devices of the apparatus are capable of reciprocating on linear lines while holding coil bobbins, and of stopping the coil bobbins at predetermined positions. The first conveying devices allow the coil bobbins to be fed from a feeding device to a coil winding device and then to be discharged therefrom after the completion of the coil winding process. The second conveying device receives the coil bobbins from the first conveying device, and then allows them to be subjected to coil finishing processes in cooperation with devices for the coil finishing processes, as the coil bobbins remain held by the second conveying device. The intervals at which the conveying devices hold the coil bobbins may be determined in such a manner that the intervals are reduced when the coil bobbins are transformed from the first conveying device to the second conveying device.

Automatic coil winding and finishing machine

A coil winding machine having a tape winder base which is movable at least vertically and is capable of effecting coil winding and taping operation on a continuous basis. A plurality of tape winding mechanisms are installed on the tape winding base, and each is provided with a tape support, a tape guide mechanism, a pad for pressing the tape against a coil, and a cutter for cutting the tape. The tape guide mechanism, the pad and the cutter constitute a taping head, and each taping head is installed detachably on a taping head support secured to the tape winder base. The tape winder base is movable in the horizontal direction as well as vertically. In this case, the ratio of the number of tape winding mechanisms can be set to one to an integer of the number of spindles.

Coil winding machine having a tape winder

A spindle supports a wound coil. On a base movable in a plane perpendicular to the spindle are supported a pad, a cutter and a tape table bearing on it a plurality of tapes. Tape is wound around the coil by the rotation of the spindle, and the cutter provided in the vicinity of the pad moves back and forth, while being pushed by the pad, to cut the end of the tape after completion of the tape winding. Tapes may be exchanged automatically when one tape is exhausted.
