The present invention relates to a suturing device capable of automatically suturing.

[Prior Art and Problems] Conventionally, when a seat used for a vehicle such as an automobile is manufactured, a predetermined pattern is used because the seat has a complicated stitch shape instead of a simple flat stitch. Or, the suture shape is drawn on the skin material using a chaco or the like, and the drawn line is manually sewn. Such sewing means often depend on the intuition and skill of the person who is suturing, and those with little work experience have poor sewing efficiency, which not only causes problems in production efficiency but also causes variations in product quality. In addition, problems such as fatigue due to long working hours have occurred.

An object of the present invention is to provide a suturing device capable of automatically sewn in the sewing of a sheet having a complicated shape and without the need for skill so that the quality can be made uniform.

Another object of the present invention is to provide a suturing device which can easily cope with changes in the shape of the seat, is highly economical, and exerts its power in producing a wide variety of products.

Still another object of the present invention is to provide a suturing device suitable for suturing a sheet with a bead.

[Means for Solving Problems] The present invention has been made to solve the above problems, and a suturing device according to the present invention includes a sewing machine body and an intermittent cross puller attached to the sewing machine body. And a roller lifter that is in harmony with the movement of the intermittent cross puller, a guide pulley that is arranged at the lower part of the roller of the intermittent cross puller and that can be moved depending on the lifting position, and a jig, and the jig is arranged on the base. The floating table and a three-dimensionally movable mounting plate mounted above the floating table, and the guide pulley and the intermittent cross puller are provided at the lower part of the outer peripheral side of the mounting plate. A guide rail guided by a roller is formed, and a skin material placed on a placing plate of the jig is stitched by the sewing machine body in conformity with the guide rail shape. .

An air pocket is formed under the base, and the air pocket is connected to an air supply device through a duct.
It is preferable that the floating table is configured to be movable by air supplied from a large number of small holes formed in a base on which the floating table is placed via air pockets.

A sliding surface may be formed on the upper surface, and the floating surface may be freely movable. As the sliding surface, a bearing or the like may be arranged to freely move, or the base D
One surface can be coated with a smooth surface, for example, fluororesin, so that the back side of the jig 3a can be made of a material that easily slides. Is also good.

According to the suturing device described above, the guide rail 3f of the jig 3 is
Is guided by the roller 2n and the pulley 4a,
It can be stitched automatically according to the desired shape.
Therefore, various sheets can be automatically stitched by changing the shape of the guide rail.

[Advantages of Device] Since the suturing device according to the present invention is configured as described above, it has the following effects.

In the case of stitching a sheet having a complicated shape, it is possible to automatically perform the stitching without any skill, and it is possible to achieve uniform quality. In addition, since the machine is sewn mechanically, it does not depend on the intuition and skill of the person who is sutured, and regardless of the length of work experience, the production efficiency is good. In addition, it is possible to eliminate conventional fatigue caused by long-time work. Moreover, since the shape of the sewn product can be changed by simply changing the shape of the guide rail, it is economical, and it is possible to sufficiently change the shape by changing the design of the seat. It exerts its power in production.

Further, by forming the holding device for stitching the bead, the bead can be stitched in accordance with the shape of the sheet, which can be performed very easily.
