Abstract

A sewing error management device includes a display portion, a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to acquire an error image obtained by drawing an occurrence position of an error on a sewing pattern. The acquiring the error image is based on coordinates representing a formation position of a sewing stitch being sewn at a time point when the error occurs in sewing of the sewing pattern formed by a plurality of sewing stitches. The acquiring the error image is also based on an image showing a shape of the sewing pattern. And the computer-readable instructions further instruct the processor to display the acquired error image on the display portion.

First claim

What is claimed is:

1. A sewing error management device comprising:
a communication interface configures to communicate with a sewing machine over a network, the sewing machine configured to sew a sewing pattern formed by a plurality of stitches;
a display portion;
a first processor; and
a memory configured to store computer-readable instructions that, when executed by the first processor, instruct the processor to perform processes comprising:
acquiring, for a plurality of errors that occur in the sewing of the sewing pattern, a total error image from the sewing machine over the communication interface;
the acquired total error image having been generated by a second processor in the sewing machine by:
acquiring coordinates representing a formation position of a sewing stitch being sewn at a time point when each of the plurality of errors occurs in the sewing of the sewing pattern;
generating an error image obtained by drawing an occurrence position of each of the plurality of errors on a sewing pattern, based on the acquired coordinates on an image showing a shape of the sewing pattern; and

displaying the acquired total error image on the display portion.

2. The sewing error management device according to claim 1 , wherein
the acquiring the error image includes
acquiring the total error image and a single error image, the single error image corresponding to one of the errors, of the plurality of errors that occur in the sewing of the sewing pattern, and the single error image being obtained by drawing the occurrence position of the one of the errors on the image showing the shape of the sewing pattern, and

the displaying of the acquired error image on the display portion includes
switching between display of the total error image and the single error image on the display portion, based on switching command information.

3. The sewing error management device according to claim 1 , wherein
the computer-readable instructions further instruct the processor to perform a process comprising:
acquiring, for each of the plurality of errors, a type of error that actually occurs from a plurality of errors that may occur in the sewing of the sewing pattern, and

the displaying of the acquired total error image on the display portion includes
displaying the acquired type of error for each of the plurality of errors on the display portion.

4. The sewing error management device according to claim 1 , wherein
the computer-readable instructions further instruct the processor to perform a process comprising:
acquiring, for each of the plurality of errors, a countermeasure associated with a type of error that actually occurs, from among a plurality of the countermeasures respectively associated with a plurality of the types of errors that may occur in the sewing of the sewing pattern, the countermeasure being used to resolve each of the errors, and

the displaying of the acquired total error image on the display portion includes
displaying the acquired countermeasure for each of the plurality of errors on the display portion.

5. The sewing error management device according to claim 1 , wherein
the displaying of the acquired total error image on the display portion includes
displaying the total error image on the display portion after the sewing machine completes the sewing of the sewing pattern.

6. The sewing error management device according to claim 1 , wherein
the displaying of the acquired total error image on the display portion includes
displaying the total error image on the display portion when the sewing machine stops the sewing of the sewing pattern in accordance with one of the plurality of errors occurring, and
maintaining a display state of the error image also after re-starting the sewing.

7. A sewing error management system comprising:
a sewing machine configured to sew a sewing pattern in accordance with coordinates representing formation positions of each of sewing stitches of the sewing pattern formed by a plurality of the sewing stitches, the sewing machine including
a first processor, and
a first memory configured to store computer-readable instructions that, when executed by the first processor, instruct the first processor to perform processes comprising:
acquiring the coordinates representing the formation position of the sewing stitch being sewn at a time point when an error occurs in sewing of the sewing pattern by:
acquiring a sewing speed set for sewing the sewing pattern and a sewing complete stitch number representing a number of the sewing stitches sewn from a start of the sewing of the sewing pattern to when the error occurs;
deciding an error range, based on the acquired sewing speed; and
deciding an error range stitch number, based on the acquired sewing complete stitch number and on the error range, using the sewing complete stitch number as a reference;
acquiring coordinates representing the formation positions of the sewing stitches corresponding to each of stitch numbers included in the decided error range stitch number; and

generating an error image obtained by drawing an occurrence position of the error on the sewing pattern, based on an image showing a shape of the sewing pattern and on the acquired coordinates using a coordinate range corresponding to the error range stitch number as the occurrence position of the error on the sewing pattern; and

an external device including a display portion displaying the image, the external device being configured to communicate with the sewing machine, and the external device including
a second processor; and
a second memory configured to store computer-readable instructions that, when executed by the second processor, instruct the second processor to perform processes comprising:
acquiring the generated error image, by the communication with the sewing machine; and
displaying the acquired error image on the display portion.

8. The sewing error management system according to claim 7 , wherein
the deciding the error range includes
correcting the error range by multiplying the error range by a correction coefficient that differs depending on a type of the error.

9. A sewing error management system comprising:
a sewing machine configured to sew a sewing pattern in accordance with coordinates representing formation positions of each of sewing stitches of the sewing pattern formed by a plurality of the sewing stitches, the sewing machine including
a first processor, and
a first memory configured to store computer-readable instructions that, when executed by the first processor, instruct the first processor to perform processes comprising:
acquiring the coordinates representing the formation position of the sewing stitch being sewn at a time point when each of a plurality of errors occurs in sewing of the sewing pattern;

generating a total error image obtained by drawing an occurrence position of each of the plurality of errors on the sewing pattern, based on an image showing a shape of the sewing pattern and the acquired coordinates; and

an external device including a display portion displaying the image, the external device being configured to communicate with the sewing machine, and the external device including
a second processor; and
a second memory configured to store computer-readable instructions that, when executed by the second processor, instruct the second processor to perform processes comprising:
acquiring the generated total error image, by the communication with the sewing machine; and
displaying the acquired total error image on the display portion.

10. The sewing error management system according to claim 9 , wherein
the acquiring the generated error i
