Production management device for sewing machine

Abstract

The invention provides a production controller for a sewing machine by which a production history of sewing can be known by simple constitution. Times indicating completion of prescribed sewing work are orderly stored in a memory for every completion. The number of completion of sewing work per unit time is calculated based on the stored times. The calculated numbers of completion per unit time are displayed on a display (21) as a graph of times against completion number and average pitch time at a prescribed time interval is also displayed. In such constitution, a production history such as time transition of complete numbers can be easily grasped to easily extract issues of production to enable efficient production control.

Description

technical field [0001] The present invention relates to a sewing machine production management device, and more specifically relates to a sewing machine production management device for measuring production management data such as operation time (takt time) of a sewing process by an operator in a sewing workshop. Background technique [0002] In the past, in order to efficiently carry out production, a production management system has been developed. For example, the average takt time of a day is calculated and displayed. In addition, the work time of a day is divided into multiple time zones, and the output of each time zone is expressed as each The operator performs display (Patent Document 1). [0003] In addition, each time zone that divides the work time of the day into a plurality of zones is set, and the average sewing time for each piece in each time zone and the average sewing time for each piece in one day are displayed (patent document 2). [0004] In addition, ...

AI Technical Summary

Problems solved by technology

[0008] However, until now, it has been difficult to judge the production process such as the number of pieces sewn from the start of production, because only the takt time (sewing time) required for one piece of sewing (sewing time) is calculated, or the average takt time of a day. production completion date, and whether the production was carried out effectively

[0009] In addition, since the production process is not recorded, in order to obtain the average takt time of any designated time zone, a timer for measuring the sewing time of each piece, a timer for measuring the designated time zone, etc. are required, and takt time measurement is available. Disadvantage of becoming complicated (patent document 2)
