Abstract

A sewing machine includes needle bars, a notification 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 perform processes. The processes include acquiring sewing data for sewing an embroidery pattern made up of a plurality of partial pattern, setting correspondences between a needle bar among the needle bars and an upper thread data set included in the sewing data, for each of the needle bars, and the sewing embroidery pattern, detecting an error that occurs during the sewing, stopping the sewing when the error is detected, specifying a change-eligible needle bar, for which the sewing is completed, when a target data set exists, the correspondence with one of the needle bars not being set for the target data set, and causing the notification portion to notify information indicating the specified change-eligible needle bar.

First claim

What is claimed is:

1. A sewing machine comprising:
a plurality of needle bars;
a notification portion;
a processor; and
a memory configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes comprising:
acquiring sewing data for sewing an embroidery pattern that is made up of a plurality of partial patterns, the sewing data including a plurality of upper thread data sets specifying types of upper threads associated with individual ones of the plurality of the partial patterns,
setting correspondences between a needle bar from among the plurality of the needle bars and an upper thread data set included in the acquired sewing data, for each of the plurality of the needle bars,
sewing each of the plurality of the partial patterns on a workpiece by operating, from among the plurality of the needle bars, a needle bar for which the correspondence with the upper thread data set is set,
detecting an error that occurs during the sewing of each of the plurality of the partial patterns,
stopping the sewing of a partial pattern being sewn in response to the error being detected,
specifying a change-eligible needle bar, which is one of the plurality of the needle bars and for which the sewing is completed, in a situation in which a target data set exists among the plurality of the upper thread data sets included in the sewing data, the correspondence with one of the plurality of the needle bars not being set for the target data set, and
causing the notification portion to notify information that indicates the specified change-eligible needle bar in response to the error being detected, wherein

the specifying of the change-eligible needle bar includes specifying the target data set and the change-eligible needle bar in a situation in which the target data set exists,
the causing of the notification portion to notify the information that indicates the change-eligible needle bar includes causing the notification portion to notify information that indicates the specified change-eligible needle bar and information that indicates a type of an upper thread indicated by the target data set,
the computer-readable instructions further instruct the processor to perform processes comprising:
setting, in a situation in which the target data set exists, at least one change timing for changing the correspondences, while the sewing of the embroidery pattern is in progress,
specifying the change-eligible needle bar for each of the at least one change timing,
causing the notification portion to notify information that indicates the specified change-eligible needle bar for the at least one change timing that is set, and
acquiring a command, in response to the error being detected, to change the at least one change timing that is set, and

the setting of the at least one change timing includes changing the at least one change timing in response to the command being acquired, based on the specified change-eligible needle bar and the specified target data set, and
the setting of the correspondences includes changing the correspondences at the at least one change timing, based on the specified change-eligible needle bar and the specified target data set.

2. The sewing machine according to claim 1 , wherein
the computer-readable instructions further instruct the processor to perform processes comprising:
determining, in response to the error being detected, whether the number of the at least one change timing is less in a situation in which the at least one change timing is to be changed than in a situation in which the at least one change timing is not to be changed, based on the specified change-eligible needle bar and the specified target data set, and

the causing of the notification portion to notify the information that indicates the change-eligible needle bar includes causing the notification portion to notify information that indicates the specified change-eligible needle bar in a situation in which the number of the at least one change timing is less in a situation in which the at least one change timing is to be changed than in a situation in which the at least one change timing is not to be changed.

3. The sewing machine according to claim 1 , wherein the computer-readable instructions further instruct the processor to perform processes comprising
causing the notification portion to notify error information that indicates that an error is occurred for as long as the error is being detected, and
the causing of the notification portion to notify the information that indicates the change-eligible needle bar includes causing the notification portion to notify information that indicates the specified change-eligible needle bar after notifying the information that indicates that an error is occurred is to be terminated.

4. The sewing machine according to claim 1 , wherein
the computer-readable instructions further instruct the processor to perform processes comprising:
acquiring an amount of a lower thread that is used by sewing in response to the error being detected, and
causing the notification portion to notify information that indicates the amount of the lower thread that is used, in response to the acquired amount being is-less than a specified value.

5. A non-transitory computer-readable medium storing computer-readable instructions that are executed by a processor of a sewing machine provided with a plurality of needle bars and a notification portion, the computer-readable instructions, when executed, instructing the processor to perform processes comprising:
acquiring sewing data for sewing an embroidery pattern that is made up of a plurality of partial patterns, the sewing data including a plurality of upper thread data sets specifying types of upper threads associated with individual ones of the plurality of the partial patterns,
setting correspondences between a needle bar from among the plurality of the needle bars and an upper thread data set included in the acquired sewing data, for each of the plurality of the needle bars,
sewing each of the plurality of the partial patterns on a workpiece by operating, from among the plurality of the needle bars, a needle bar for which the correspondence with the upper thread data set is set,
detecting an error that occurs during the sewing of each of the plurality of the partial patterns,
stopping the sewing of a partial pattern being sewn in response to the error being detected,
specifying a change-eligible needle bar, which is one of the plurality of the needle bars and for which the sewing is completed, in a situation in which a target data set exists among the plurality of the upper thread data sets included in the sewing data, the correspondence with one of the plurality of the needle bars not being set for the target data set, and
causing the notification portion to notify information that indicates the specified change-eligible needle bar in a situation in which the error is detected, wherein
the specifying of the change-eligible needle bar includes specifying the target data set and the change-eligible needle bar in a situation in which the target data set exists,
the causing of the notification portion to notify the information that indicates the change-eligible needle bar includes causing the notification portion to notify information that indicates the specified change-eligible needle bar and information that indicates a type of an upper thread indicated by the target data set,
the computer-readable instructions further instruct the processor to perform processes comprising:
setting, in a situation in which the target data set exists, at least one change timing for changing the correspondences, while the sewing of the embroidery pattern is in progress,
specifying the ch
