Abstract

PURPOSE:To automatically wind a wire to a body for winding in order to improve working efficiency and reduce failure rate by blowing compressed air in the direction crossing the wire winding surface at least between the wire inserting process and winding process. CONSTITUTION:A wire 4 is supplied when the upper roller 142 of a second wire feeder 113 is driven to rotate and this wire 4 is attracted by a first wire attracting device 125 through a square hole 5 of a head chip 3. When the wire 4 is attracted to a certain degree, the lower roller 156 of the second wire feeder 113 is moved in such a direction as becoming far from the upper roller 142 and thereafter the feeder 113 is moved to the first position. While the wire 4 is attracted into a sleeve 17, compressed air is injected toward the head chip 3 from a nozzle 184 of a second blow pipe 183 and is sprayed to the wire 4 to be wound by the head chip 3. Therefore, the wire 4 to be wound to the head chip 3 is wound to the specified position without riding over the head chip 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a wire winding method for automatically winding a wire.

Therefore, the applicant proposed a device capable of automatically performing the above-mentioned winding work, which is disclosed in Japanese Patent Application No. 59-91226, ``Winding Machine.'' )] uttered. This device performs multiple windings by forcing a wire (4) through a square hole (5) and rotating the head chip (3) relative to the wire (4). Therefore, the wire (4) is connected to the square hole (5)
The columnar parts (5a) and (5b) constituting the magnetic circuit on both sides of the
).

However, according to the above-mentioned winding wire method, as shown in Fig. 2 @, after the wire (4) is wound around one columnar part (5a), when it is wound around the other columnar part (5b), , often crosses the square hole (5) like the wire (4a), causing a problem that becomes an obstacle to subsequent wire insertion. Furthermore, it has the disadvantage that during one winding, the winding protrudes from the winding area like wire (4b).

[Purpose of the invention]

The present invention has been made in view of the above-mentioned incident, and it is an object of the present invention to provide a wire winding method that can automatically wind a wire around a body to be wound without causing winding defects.

[Summary of the invention] A wire is inserted through a through hole in a wound body, and this wire is
In a winding method in which the wire is wound by rotating it relative to the wire body, compressed air is applied in a direction intersecting the wire winding surface at least between the wire insertion step and the winding step. It was designed to be sprayed on.

is driven by the X-direction cylinder (12B)K and moves to its forward position, and its sleeve (171) protrudes to face the square hole (5)K of the head chip (3). Here, the sleeve (171) is located coaxially with the square hole (5), and the first wire feeding device (112) is located at its first position and is spaced apart from the sleeve (171). ing. Next, the vacuum pump (182) is driven to generate a suction force on the first suction device (125), and the arm (

The wire (4), which is held between the lower roller CI and the lower roller CI, is fed out for a certain length. Thereby, the fed wire (4) passes through the square hole (5) of the Herad tip (3) and is sucked from the sleeve (171) into the vibe (170). Subsequently, as shown in Figure 1 (C), the sleeve (171) of the wire suction device (125) is moved to its retracted position, thereby clamping the wire (4) with the elastic body (174). Thereafter, the first wire feeding device (112) is moved together with the wire suction device (125) to its retracted position, and the head tip (3) is pulled from the pipe (170) until it reaches the length required to be wound. Pull out the wire (4),
And connect the wire (4) to the arm and sleeve (171)

is rotated upwards. Next, as shown in FIG.
) The wire (4) is wound once on the negative side of the square hole (5).

In addition, in this second position, the head chip (3) is in a state in which the central axis of the square hole (5) is located parallel to the guide rail (90).

Then, the I-th holding member (to) of the holding means a is rotated toward the head chip (3), and its elastic body (to) is pressed against both sides of the square hole (5) of the head chip (3). Prevent loosening of the wire (4) wrapped around the lever. Subsequently, as shown in Figure 1 (K), after the first wire feeding device (112) moves from its first position to its second position with the clamping body (155) open, When the holding body (155) is in the closed state, the upper roller (142) and the lower roller (156)
) and the end of the wire (4) on the side of the suction device (112) is held between the two. Next, the cutter of the wire feeding device (112)

Therefore, even if the wire (4) becomes slack due to the first wire feeding device (112) approaching in the direction of the holding means aυ, the wire (4) is prevented from becoming tangled or twisted. . Then, the first wire feeding device (
112) moves, the front end of the wire (4) cut by the cutter + (164) of the first wire feeding device (i12) is cut by the first head tip (1) as shown in the second figure (@). 3). Simultaneously with the movement of the first wire feeding device (112), the second table (92) is driven by the drive motor (95) to approach the holding means (111). As well as being moved in the direction of
The second suction device (1
26) is driven so that the tip of its sleeve (171) faces the square hole (5) of the head chip (3). In this state, the upper roller (142) of the first feeding device (112)
is rotationally driven, and the wire (4) is sent out toward the head chip (3). At the same time, the vacuum pump (182
) is activated, and the sleeve (1) of the second suction device (126) is activated.

) transfers the head chip (3) from the first feeding device (112).
) is sucked into the second suction device (126) through the square hole (5). When the wire (4) is suctioned to the extent that it tumbles, the first
The lower roller (156) of the wire feeder (112) is driven in the direction away from the upper roller (142), and then the first wire feeder (112) is moved from the 20th position to the first position. and a pair of rollers (142) (15
Wire (4) comes off from 6). Then, the above wire (
The part on the right side of the Herad tip (3) in 4) is completely suctioned by the second wire suction device (126). In this way, one end side of the wire (4) is suctioned by the second suction device (126).
6), the sleeve (171) is moved to the retracted position and the wire (4) is gripped by the elastic body (174). Next, as shown in FIG. The second suction device (126) is moved in the retracted position at.Therefore, the wire (4) is stretched between the head tip (3) and the second suction device (126). , the first table (91) is driven in a direction away from the holding means, and the first feeding device (112) and suction device (125) are retreated to predetermined positions.

During this time, the first feeding device (112) is rotated 180 degrees in the opposite direction and returned to its initial position. Subsequently, after rotating the first holding member (to) of the holding means I and separating it from both sides of the square hole (5) of the head chip (3), the holding means (111) is moved together with the head chip (3). Rotate 180 degrees counterclockwise from the second position shown in the figure to the first position. Then, actuate the end of the first presser member again to insert the elastic material (3) into the square hole (3) of the head hep (3). 5) to prevent the wire (4) wound here from loosening.Next, as shown in FIG. 5(I), the second wire feeding device (113) The front end of the wire (4) is held between the upper and lower rollers (142) and (156).Then, the cutter (164) of the second feeding device (113) ) is activated and the wire (
4) is the feeding device (113) and the second suction device (126)
will be disconnected between.

Subsequently, the second wire feeding device (126) is moved to its advanced position and rotated 180 degrees during the movement. In addition, as shown in Figure 1 (GT), the front end of the cut wire (4) is inserted into the square hole (5) of the head chip (3).
In addition, the first wire feeding device (112) and the first wire suction device (125) are moved to their forward positions, and the sleeve (171) of the suction device protrudes and its tip forms a square hole ( 5) Opposed to. In this state, the upper roller (142) of the second wire feeding device (113) is rotationally driven to feed the wire (4).
) is sucked into the first wire suction device (125) through the square hole (5) of the Herad tip (3). When the wire (4) is attracted to a certain extent, the second wire feeding device (113
) is moved in a direction away from the upper roller (142), and then the feeding device (113) is moved to the first position. Thereby, the wire (4) comes off from between the rollers (142) and (156) and is sucked into the first wire suction device (125). by this,
