Abstract

PURPOSE:To obtain perfect sewing correction data by correcting a pitch, upper feed rate and needle thread feed rate simultaneously, by determining an absolute correction value indicating sewing characteristics inherent in each sewing machine under reference sewing conditions, and by determining a correction coefficient on the basis of the absolute correction value. CONSTITUTION:A factory engineer selects an absolute correction value determination mode and inputs a reference presser bar pressure, reference number of revolutions, reference number of needles, reference pitch, reference cloth and reference string by an operation key 2. In this state, trial sewing is conducted, and sewing length and cloth deviation are measured. Actual pitch is operated by a correction value arithmetic circuit 4 on the basis of the measuring results. A pitch correction value, needle thread feed rate correction value and upper feed rate correction value are operated on the basis of the measuring results, actual pitch and inputted reference sewing conditions and respectively stored in a storage circuit 3. A correction value setting mechanism part 7 sets a machine mechanism part 6 on the basis of this correction value, conducts trial sewing again, and when this sewing quality is within the tolerance of a desired value based on the reference sewing conditions, stores the correction value as the absolute correction value of sewing machine in a correction data storage circuit 5.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sewing machine, and more particularly to a sewing machine capable of calculating a sewing correction coefficient that can be transferred to other sewing machines necessary to perform sewing consistent with set sewing conditions. , [Prior Art] Conventionally, in sewing machine control mechanisms such as double-thread feeding devices and top feed devices where pitch is the basic element of control thread data, fabric If the machine pitch differs from the actual pitch because of a deviation in the feed amount, the machine pitch is changed to correct the cloth feed amount. As a result of this change, the upper thread supply amount and upper feed amount to achieve the specified sewing specification pitch will also be affected. Therefore, it is necessary to change the upper thread supply amount and upper feed amount at the same time. There is a drawback that no changes have been made.

Furthermore, in the present invention, this correction value is divided by the absolute correction value of the sewing machine stored at the factory to calculate a correction coefficient under the input desired sewing conditions and stored in the correction data storage circuit 5. (Blocks 30 and 31). When sewing with another sewing machine under the same sewing conditions as the input desired sewing conditions, this correction coefficient is determined by multiplying the absolute correction value of the other sewing machine by the correction coefficient. This is used to determine the correction value of the other sewing machine without trial sewing. That is, multiplying the correction coefficient obtained by one sewing machine by the absolute correction value of another sewing machine means that the correction value of the one sewing machine is converted to the correction value of the other sewing machine, With the other sewing machine, correction values can be obtained under the same sewing conditions without trial sewing.
