Abstract

PURPOSE:To ensure stable quality and eliminate defective quality due to 'walk ing' and 'falling' by providing a means for relatively turning a sleeve about the vicinity of a sleeve edge, and a sensor for stopping the aforesaid means after sensing the turning position of the sleeve, respectively on sleeve bars. CONSTITUTION:The piston of a 'walking' cylinder 20 is made to expand and a sleeve retaining bar 16 is oscillated toward a close direction via an oscillation lever 19. The forward end of a sleeve 14 is thereby held between the pad 17 of the sleeve retaining bar 16 and a sleeve slide board 15. In this state, a 'walk ing' motor 21 is rotated in a normal direction and a motion bed 19 is moved in direction off the motor 21. The sleeve 14 turns on sleeve bars 2-1 to 2-9 about the vicinity of a sleeve edge and the forward end of the sleeve 14 moves left along the sleeve slide board 15. A 'walking' sensor 23 thereby becomes unable to detect the forward end of the sleeve 14. When the 'walking' motor 21 is reversed and the motion bed 18 is moved right, the forward end of the sleeve 14 is detected with the sensor 23. It follows, therefore, that when the motor 21 is stopped, the sleeve 14 can be positioned at the predetermined turning position set with the sensor 23, relative to the aforesaid sleeve bars 2-1 to 2-9.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sleeve attachment position adjusting device for a three-dimensional sewing machine, and in particular, to a sleeve supporter for rotating a sleeve to a predetermined rotation position around its shoulder with respect to a sleeve bar. This invention relates to a sleeve attaching position adjusting device for a three-dimensional sewing device.

(Prior Art) As a sleeve attaching device for three-dimensionally stitching a body part and a sleeve that have been processed as parts, for example, Japanese Patent Application Laid-Open No. 63-29691 and No. 63-29692 (Japanese Patent Application Laid-open No. 63-29692 (Japanese Patent Application Laid-open No. 63-29692)
and Japanese Patent Application No. Sho 61-1) No. 0887) are known.

In this type of device, the shoulder part of the sleeve is fitted into the sleeve bar of the sleeve support part that can be expanded and expanded in the radial direction like an umbrella rib on the left and right.
Next, the body is attached to the body support section.

Next, the sleeve support part with the sleeve attached is combined with the body support part,
The sleeve is transferred to the body support, and the clamp needle is protruded from the inside of the body support to clamp and fix the sleeve to the body support.

After the transfer of the sleeve is completed, the sleeve support part contracts, and the sleeve support part is separated from the body support body diagonally upward to the right or diagonally upward to the left by the action of both the sleeve vertical motor and the sleeve width motor.

The sleeves and body are then three-dimensionally sewn using an articulated robot equipped with a small sewing machine at its tip.

Figures 3 and 4 show the workpiece A thus obtained, with B being the body and C being the sleeves.

In such a conventional three-dimensional sewing device, in order to determine the rotational position of the sleeve near the shoulder with respect to the body support, a mark is formed in advance on the sleeve bar of the sleeve support either directly or by optical means using a marking light. , the notch provided on the sleeve is visually aligned with the above mark.

[Problem to be solved by the invention]

However, conventional sleeve positioning as described above is based on visual inspection by the operator, which can lead to variations, long positioning times, longer cycle times, and problems such as "walking" and "falling over." There was a problem with the quality of the sewing.

In addition, in the process of attaching left and right sleeves, the state in which the left and right sleeves are shifted forward or backward from the center of the body armhole is called "walking", and the state in which they are both shifted forward or backward is called "falling down".

[Means to solve the problem]

The sleeve attachment position adjusting device of the three-dimensional sewing device of the present invention includes a body support body, a sleeve support body having a sleeve bar that can be expanded and contracted in the radial direction, and a sleeve support body that moves the sleeve support body toward the body support body. In the three-dimensional sewing device, the three-dimensional sewing device includes means for transferring the sleeve on the sleeve bar to the body support member, and means for fixing the transferred sleeve to the body support member. means for specifying a central rotational position, the specifying means releasably clamping the tip of the sleeve, and rotation of the sleeve relative to the sleeve bar about the vicinity of the shoulder. [Features] Sleeve setting position 1 of the three-dimensional sewing device of the present invention [Adjusting device] In this case, the sleeve is attached to the sleeve bar of the sleeve support at a predetermined angular position determined by the gait sensor.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, l indicates one of the left and right sleeve supports, and the sleeve support l has, for example, nine sleeve bars 2-1 to 2-9 arranged in a generally horseshoe shape opposite to the body bar. These sleeve bars are attached to a sleeve bar movable base 5 via a sleeve bar link plate 3 and a sleeve bar link base 4. A guide shaft 6 and a hole screw are supported on the stand 5. A ball nut 8 fixed to the base 5° is screwed into the screw. A motor (not shown) is attached to the lower end of the hole screw via a holding plate 9. As a result, when the motor rotates, the hole screw rotates, and the sleeve bar movable base 5 is guided by the guide shaft 6 and can move up and down together with the sleeve bars 2-1 to 2-9.

The upper ends of the guide shaft 6 and the hole screw are supported by a plate 11.

The sleeve bars 2-1 to 2-9, the guide shaft 6, etc. are supported by the sleeve support shaft 12. The lower end of the shaft 12 is fixed to a moving table 13.

Reference numeral 14 indicates a sleeve attached to the sleeve support 1.

In the present invention, the sleeve sliding plate 15 is fixed to the sleeve sliding plate 5, and the inner surface of the pad 17 provided at the tip of the bolt bar 16 is brought into contact with the outer surface of the sleeve sliding plate 15. The base of the ember 16 is rotatably supported on the movable table 18.

Further, a swinging rod 19 is provided protruding from the base of the sleeve presser 16,
The tip of the piston of the walking cylinder 20 and the base of the walking cylinder 20 are pivotally supported by the tip of the swinging rod 19 and the moving table 18, respectively, and the ball screw 22 is driven by the walking motor 21 fixed to the sleeve sliding plate 15. The movable table 18 is moved in the direction toward and away from the motor 214 through the motor 214.

Further, an optical walking sensor 23 of the sleeve 14 is provided at a predetermined position on the outer surface of the sleeve sliding plate 15.

Since the sleeve attaching position adjusting device of the three-dimensional sewing device of the present invention has the above-described configuration, first, the piston of the walking cylinder 20 is extended and the sleeve presser bar 16 is swung in the closing direction via the swinging rod 19 to adjust the sleeve presser. The tip of the sleeve 14 is held between the pad 17 of the bar 16 and the sleeve sliding temporary 15, and in this state, the walking motor 21 is rotated in the forward direction to move the moving table 18 in a direction away from the walking motor 21.

Due to this operation, the sleeve 14 rotates on the sleeve bars 2-1 to 2-9 around the shoulder area, and the tip of the sleeve 14 rotates on the sleeve sliding plate I.
5 to the left in FIG. 1, and as a result, the walking sensor 23 is in a prone position in which it does not detect the tip of the sleeve 14.

Therefore, next, the walking motor 21 is reversed to move the moving table 18 to the first position.
If you move to the right in the figure, the tip of the sleeve 14 will be detected by the walking sensor 23, so if you stop the walking motor 21 at this point, the walking sensor 23 will move against the sleeve bar.
The sleeve 14 can be positioned at a predetermined rotational position determined by
-1 to 2-9 from the first position (W to the point where you can adjust the walking and falling of the sleeve by reducing it slightly from the maximum enlarged position) to the size position (
When the sleeve 14 is enlarged to the maximum enlarged position, positioning of the sleeve 14 is completed.

The above operation is the same for both the left and right sleeves, but the actual operation for the right sleeve is as shown in FIG. 2, for example.

That is, ■ The operator attaches the shoulder end of the sleeve 14 to the sleeve bars 2-1 to 2-9 of the sleeve support l, and when the foot switch is pressed, the sleeve motor (not shown) is activated to move the sleeve bars 2-1 to 2-2. -9 expands from the origin position to the first position.

(2) When the operator steps on the foot switch for the second time, the walking cylinder 20 is extended and the tip of the sleeve is held between the pad 17 of the sleeve presser bar 16 and the sleeve sliding plate 15. Next, the walking motor 21 rotates forward according to the output of the walking sensor 23, and the sleeve 14
If the tip of the sleeve 14 moves to the left in FIG. 1 and as a result the detection output of the sensor 23 disappears, then the walking motor 21 is reversed to move the tip of the sleeve 14 to the right in FIG. When the tip of the sleeve 14 is detected again by the walking sensor 23, the walking motor 21 is stopped. This allows for adjustment of the sleeve walk.

- When the sleeve walking adjustment is completed, the walking cylinder 20 is contracted and the sleeve is released from the sleeve presser 16.

■After the sleeve positioning is completed, the sleeve bars 2-1 to 2-9 are expanded from the first position to the size position to completely complete the sleeve positioning and clamping.

〔Effect of the invention〕

The sleeve attachment position adjustment device of the three-dimensional sewing machine of the present invention can automatically position the sleeve in the rotational direction, so the quality is stable and it is possible to "walk".

Eliminates quality defects due to "falling over".

Furthermore, since the operator can automatically position the sleeve in the rotational direction simply by setting the sleeve on the sleeve support, there are various benefits such as a reduction in cycle time.
