Benefits of technology
The present invention provides a sewing method that allows for the creation of aesthetically beautiful stitches even when sewing thick or rigid articles. The method prevents needle bending and positional displacement, which reduces the area of stitch hole openings and improves the appearance of the sewed article. Additionally, the method reduces the cost by avoiding the need for frequent needle replacement.
Problems solved by technology
That is, this technology cannot be applied to an article to be sewn in which the thickness barely changes.
Furthermore, it is difficult to support an article to be sewn that is thick and has high rigidity, such as an instrument panel, with a post bed.
For these reasons, the technology described in JP H03-039187 Y is not easy to implement for an article to be sewn that is thick or has high rigidity.
Ultimately, when sewing an article to be sewn that is thick or has high rigidity, it is difficult to avoid causing bending (plastic deformation) of the needle.
This makes it necessary to frequently exchange the needle, and therefore the cost is significantly increased.
Due to this positional displacement, the area of the openings of the stitch holes increases, which negatively affects the appearance.

Embodiment Construction
[0024]Preferred embodiments of a sewing method according to the present invention will be presented and described in detail below with reference to the accompanying drawings in connection with a sewing device for implementing the sewing method. In the following description, the terms “up”, “down”, “left”, and “right” corresponds to upward, downward, leftward, and rightward in each drawing, but these directions are merely shown for convenience in order to facilitate understanding, and do not define the directions when actually using the sewing device.
[0025]FIG. 1 is a schematic configurational diagram of a sewing device 10 according to the present embodiment. This sewing device 10 includes a holding mechanism 12, a sewing mechanism 14, and a sewing robot 16 serving as a transport device (transport mechanism) that transports the sewing mechanism 14. The sewing mechanism 14 is attached to a tip arm 18 of the sewing robot 16 formed by an articulated robot.

In a first step, a needle pierces into an object to be sewed by reciprocal motion and leaves from the object to be sewed after the tip of the needle has penetrated therethrough. At this time, the needle is placed in a state of being stopped relative to the object to be sewed. In a second step, the needle leaves from the object to be sewed. At this time, the needle is moved relative to the object to be sewed along a sewing direction (sewing line).
Description
TECHNICAL FIELD[0001]The present invention relates to a sewing method for forming stitches in an article to be sewn with a needle and a looper, and to a device for the same.BACKGROUND ART[0002]In order to create a sense of luxury in the cabin of an automobile, stitching patterns may be sewn (stitched) in an instrument panel. Recently, attempts have been made to perform this sewing with a sewing robot having a sewing machine, which is a sewing mechanism, provided on a tip arm thereof. In such a case, the sewing robot moves the sewing machine along the instrument panel in order to create continuous stiches.[0003]Generally, when sewing, the needle pierces and penetrates through the article to be sewn during the outgoing motion, and withdraws from the article to be sewn during the return motion. During this time, the article to be sewn moves relative to the needle. In a case where the article to be sewn is an instrument panel, the interior material forming the instrument panel is made o...
