Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a support structure for a body and sleeves in three-dimensional sewing of suits and the like.

[Conventional technology]

Normally, when sewing sleeve attachments for suits, jackets, etc., the sleeve attachment part 5 of the sleeve 4 processed as shown in Fig. 11 is sewn into the armhole 2 of the body 1 processed as shown in Fig. 10. The process of putting it on is taken. Conventionally, the body 1 and the sleeves 4 were sewn together manually by an operator while aligning the planned sewing lines 3 and 6 of each part 1 and 4, respectively.

However, since the body 1 needs to have a bulge in the vicinity of the shoulder part 8 of the sleeve attachment part 5 of the sleeve 4, a part 7 of the sleeve 4 must be sewn, and there are many wrinkles in this area. Occur. Then, when sewing, the body 1 and the sleeve 4 are kept in a proper relative position, going around the armhole 2, and the sleeve attachment part 5 of the sleeve and the armhole 2 of the body 1 are sewn together, and at the same time, the sew-in part 7 is shirred. Since sewing is performed while sewing, skill and time are required, it is difficult to obtain a constant sewing quality, and productivity is extremely low.

Therefore, in an attempt to automate the conventional manual sleeve attaching process, a so-called three-dimensional sewing device has been proposed, which supports and sews the body and sleeves three-dimensionally.

FIG. 12 is a side view showing the overall configuration.

In the figure, a table 10 provided on a support stand 9
A pair of sleeve supports 11a, 11b and a body support 12 are erected, and the sleeve supports 11a, 1
Sleeves 4a and 4b are supported on 1b, and body 1 is aligned and supported on body support 12. On the other hand, an articulated robot 13 is provided on the robot support stand 13A, and a small sewing machine 14 mounted on the tip of the arm of the robot 13 is moved three-dimensionally to sew the body 1 and the sleeves 4a, 4b. It is completed.

Further, the sleeve supports 11a, 11b and the body support 12 have a structure shown in FIG. 13.

That is, as shown in FIG. 13, the body support 12 includes a support shaft 15 that rotates by a drive means (not shown), a shoulder support member 16 that moves up and down as the shaft 15 rotates, and a shoulder support member 16 that moves up and down as the shaft 15 rotates. An elevating shaft 17 protruding from the center of the member 16 so as to be movable up and down, and a clamp arm 19 having clamp members 18a and 18b at both ends and moving up and down together with the elevating shaft 17 are provided. Note that 16a and 16b are the shoulder support members 1.
The support pieces 6 are arranged in an inverted U-shape on both sides of the armhole 6, and the arrangement interval can be increased or reduced depending on the size of the armhole 2 to which the armhole 2 is attached.

On the other hand, the sleeve supports 11a and 11b are connected to the table 10.
A plurality of sleeve support bars 11a ₁ are erected on the top facing each other and arranged in a cylindrical shape at equal intervals.
11b ₁ . Further, these sleeve support bars 11a ₁ and 11b ₁ are respectively connected to the sleeve support body 11.
It is designed to expand and contract in the radial direction by a drive mechanism provided inside a and 11b.

For these supports, body 1 and sleeves 4a, 4
To set sleeves 4a and 4b in a ready-to-sew state as shown in FIG.
11b, and then set the body 1 on the body support 1.
2, the clamp arm 19 is lowered, the shoulders of the body 1 are fixed in proper positions by the clamp members 18a and 18b, and then the body support 12 is lowered to join the body 1 to the sleeves 4a and 4b, The set operation is completed.

[Problem to be solved by the invention]

However, since high precision is required for the joining position of the sleeves 4a, 4b and the body 1, when setting the body support as described above, the operator manually positions the shoulder parts of both sleeves 4a, 4b. It is necessary to accurately join body part 1 while adjusting. In other words, sleeve 4
Even if the sleeves 4a and 4b are supported by the sleeve supports 11a and 11b, the shoulder parts 8 and 8 of the sleeves 4a and 4b are sewn, and these parts 8 and 8 are attached to the supports 11a and 11b.
a and 11b, and misalignment is likely to occur. Therefore,
Even after being supported by the sleeve supports 11a, 11b, it is necessary to hold the positions of the sleeves 4a, 4b by hand until the setting is completed.

At this time, in the case of the conventional device, since the body 1 is joined to both sleeves 4a, 4b at the same time, both sleeves 4a, 4b are joined at the same time.
It is necessary to simultaneously adjust the position of point (b), and it takes a considerable amount of effort for one worker to do this, and it is extremely difficult to achieve accurate positioning. Although it is conceivable that the setting work be carried out by two workers, this would not sufficiently achieve the labor saving which is the original purpose of this type of device.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a fabric support device for a three-dimensional sewing machine that allows even one worker to easily and accurately set both sleeves to the body.

[Means to solve the problem]

This invention provides a pair of cylindrical sleeve supports that three-dimensionally support a pair of left and right sleeves facing each other on a support base. The sleeve support member is constructed of a pair of shoulder support members that support the sleeve support members, and a drive means that moves these members independently forward and backward with respect to the sleeve support member.

[Effect]

In this invention, since the pair of shoulder support members of the body support can be independently moved forward and backward relative to the sleeve support, the operator can use both hands to reliably set the sleeves one by one. A good setting condition can be obtained even by a single operator.
