Will be described below with reference to.

First, by moving the warp extracting tool 40 to the front, the warp 24 fed from the warp 24 group previously wound around the beam 26 by the warp delivering tool 68 is
It is supported and extracted in the thread fitting groove 30.

At this time, by driving the drive motor 44, a drive gear (not shown) axially attached to the drive motor 44 rotates, and the lower edge of the warp extracting tool 40 meshed with the drive gear is engraved. The rack teeth 42 thus driven are driven, and the warp yarn extracting tool 40 moves forward.

Further, the warp yarn 24 is first guided from the projecting apex portion 36 of the upper circular portion 32 along the outer peripheral edge on the left side in FIG. 5 into the lower yarn fitting groove 30, and then into the yarn fitting groove 3. The lower part of the guided warp 24 is horizontally moved along the outer peripheral edge on the right side in FIG. 5 from the projecting top 38 of the lower circular portion 34, so that the warp 24 is horizontally inserted into the thread fitting groove 30 of the warp extractor 40. Located in.

Further, the sensor 70 installed in the warp extracting device 40 detects the extraction of the warp 24, and the controller 60 stops the forward movement of the warp extracting device 40 by this detection signal.

Next, the draw-per pin extractor 54 is moved up to a position where the suction port 58 contacts the lower part of the dropper pin 18, and the dropper pin support 46 is moved forward, so that the dropper pin 18 group is warped. It is moved to the vicinity of the extraction position (see FIG. 8A).

At this time, by driving the drive motor 52, the drive gear 50 axially attached to the drive motor 52
Rotates, the rack teeth 48 engraved on the lower edge of the dropper pin support 46 engaged with the drive gear 50 are driven, and the dropper pin support 46 moves forward.

Next, by the dropper pin extractor 54,
The tipmost dropper pin 18 of the group of dropper pins 18 in a plurality of rows supported by the dropper pin support tool 46 is adsorbed and extracted (see FIG. 8B).

At this time, the suction motor, which is the suction mechanism 56, sucks air to suck the dropper pin 18 from a plurality of suction ports 58 provided at the tip of the dropper pin extractor 54.

Next, the sensor 64 is attached to the dropper pin 18
Is detected, and the controller 60 raises the dropper pin extractor 54 by this detection signal (see FIG. 8).
(C)).

This puts the dropper pin 18 extracted by the dropper pin extractor 54 in a floating state with the dropper pin support member 46, and simultaneously moves with the other dropper pin 18 group when the other dropper pin 18 group retracts. This is to prevent

Next, the dropper pin 18 of the sensor 64
The controller 60 retracts the dropper pin support tool 46 in response to the suction detection signal of (1) to move the group of dropper pins 18 other than the extracted dropper pin 18 (see FIG. 8D).

This is to isolate the other group of dropper pins 18 supported by the dropper pin supporter 46 from the warp insertion work place.

Simultaneously with the retreat of the dropper pin support tool 46, the dropper pin extractor tool 54 is lowered and the suction port 5
8 is positioned below the dropper pin 18, and the attraction with the dropper pin 18 is released.

Next, the predetermined heddle 12 is extracted.

At this time, the predetermined heddle 12 is usually extracted manually, but it can also be mechanically extracted.

Next, the warp yarn 24 extracted by the warp yarn extracting tool 40 is inserted into the insertion hole 16 of the extracted heddle 12 and the insertion hole 22 of the extracted dropper pin 18 by a thread insertion device 66 such as a hook. .

At this time, the extracted warp threads 24 are thread-fitting grooves 3
Since it is positioned horizontally (supported) within 0, the threading operation by the thread insertion tool 66 is easy.

Next, the heddle 12 and the dropper pin 18 through which the warp 24 is inserted are moved forward (left side in FIG. 8) (see FIG. 8 (e)).

Next, the sensor 62 detects the forward movement of all the dropper pins 18 in the plural rows in which the warp threads 24 are inserted, and the controller 60 moves the warp thread extractor 40 forward again by the detection signal. Prepare for the next process.

By repeating this operation, the warp yarns 24 can be successively inserted into the respective healds 12 and the respective dropper pins 18.

In this example, the upper circular portion 32 of the warp extractor 40 has a semi-elliptical shape on a plane, and the lower circular portion 34 has a substantially circular arc shape similar to a right-angled triangle on a plane. Any arcuate shape in which the positions of the tops 36 and 38 are displaced may be used.

The dropper pin support 46 may have any structure as long as it can support a plurality of groups of dropper pins 18 to be used.

Further, although the suction mechanism 56 is a suction motor, it may be a suction valve opening / closing operation, and may be any means having a suction function.

Further, according to the present invention, the warp threads 24 are inserted into the heddle 12 and the dropper pin 18 at the same time. However, when the warp threads 24 are inserted only in the heddle 12 without inserting the warp threads 24 into the dropper pin 18, Can be applied to the insertion of the warp thread only in the heddle 12 by moving the warp extractor 40 to the corresponding position of each heddle 12 group by computer control.
