Description

Sewing machine and sewing method using the same

The present invention relates to a sewing machine and a sewing method, and more particularly to a sewing machine capable of automatically setting various sewing processes in a sewing machine in a sewing machine, thereby performing a plurality of sewing processes and sewing using the sewing machine method.

As a mechanical device for sewing various fabrics, the sewing machine has been developed to study sewing machines with various functions as the necessity for diversification and high-grade sewing products increases and the production capacity is rapidly increased. Recently, the sewing parameters such as the spindle speed, the stitch width, and the thread tension which have been set in the sewing machine are input into the sewing machine in the form of data by manual operation by the operator, and the sewing machine automatically set according to the input data has been put on the agenda.

An example of a sewing machine that automatically sets a sewing parameter as described above is disclosed in Korean Laid-Open Patent Publication No. 10-2009-0103816. The sewing machine that performs the sewing process. However, the sewing machine disclosed in the above patent document requires separate input of sewing material for each sewing process, and thus there are limitations in smoothly performing various sewing processes in accordance with a desired order. For example, as shown in FIG. 1, when the process S composed of S1 to Sn is performed using the sewing machine of the related art, the sewing process (S1, S2, S3) can be performed by the same model (ie, the sewing machine represented by KM-235). However, since it is necessary to manually change the sewing parameters 30 for each sewing process (S1, S2, S3) to set the sewing machine, it is difficult to perform a plurality of sewing processes using a single sewing machine of the same model. Therefore, according to the prior art, when a plurality of sewing processes are performed, there is a problem that an increase in the number of sewing machines and operators required, an increase in production cost and work time, and a reduction in productivity are caused.

Moreover, the prior art sewing machine not only cannot automatically change the corresponding sewing parameters to perform a plurality of sewing processes, and even if it is assumed to have a means capable of executing a plurality of sewing processes, in the prior sewing process S1 of a plurality of sewing processes, if sewing failure occurs, It will go directly into the subsequent sewing process S2, and there is absolutely no chance of correction. As shown in Fig. 2, in the pre-sewing process S1, even if the sewing thread is formed by the number N of stitches set corresponding to the sewing parameter 30, the sewing may occur unexpectedly due to the operator's proficiency or the material characteristics of the fabric 1. The thread cannot reach the desired position (P ₀ is the starting point of the sewing process S1, and P ₁ is the position of the end point of the sewing process S1). However, in the prior art, even if such a sewing failure occurs, there is no chance to correct the sewing failure in the preceding sewing process S1, but the sewing machine is directly set according to the sewing parameter 30 for the subsequent sewing process S2, so that the sewing failure cannot be solved. The problem, and the subsequent sewing process S2 also inevitably causes sewing failure. Therefore, there is a problem that the quality of the sewing product is degraded and the consumer's trust in the product is lowered.
