2. HOW TO SET THE PRODUCTION SUPPORT FUNCTION
2-1. Overview of the work support function
The production support function is achieved by installing the IT-100 operation panel (Intelligent Terminal) to
the sewing machine and operating it. This function measures the operating status of the sewing machine and
visually displays the measured data on the operation panel to help improve efciency of sewing work in vari-
ous aspects. Measured and recorded data on the operation status of the sewing machine can be loaded on
a personal computer by way of Ethernet or various data storage media. It is therefore possible to analyze the
data by means of IA-1 and to accumulate the results of the analysis on the personal computer by gathering
detailed operation data from two or more sewing machines and loading them on the personal computer. As a
result, the continued efciency-improving activities for the entire sewing plant can be carried out.
* Refer to the Help for the IA-1 for the details of the IA-1.
The production support function by means of the IT-100 is categorized into four functional parts, i.e., work
management function, pitch time monitor function, sewing recorder function and production management
function. Each of them has its own support capability. Use them by selecting an appropriate one according to
your needs.
* It should be noted that the work management function cannot be disabled since it manages data on the
sewing machine operation. Operation of the other three functions can be changed over between the en-
able and disable.
(1) Work management function
To use the work management function, work history data such as the operator ID, product number and
process number, which are to be embedded in the operation data recorded by each sewing machine,
should be entered. The IA-1 carries out operational status analysis based on those pieces of data.
This function is also used when loading the operation data from the sewing machine into a personal com-
puter.
(2) Pitch time monitor function
With the pitch time monitor function, it is possible to specify an arbitrary target section to monitor the
transition of the production volume (i.e., the quantity of sewn items) per unit time and the pitch time dis-
tribution and display them on the IT-100 as a bar chart. In addition, the operational status such as the
total production volume and average pitch time in the specied section can be analyzed and indicated
numerically. Through these capabilities, the sewing work can be monitored over a long time and visually
analyzed to enable tracking down of the time when a problem has occurred.
(3) Sewing recorder function
The sewing recorder function continuously measures the number of revolutions and thread trimming
timing of the sewing machine at all times to show the results on the IT-100 as a line chart. The sewing
machine operator's skill level is checked and technical training is provided based on the line graph. It is
possible to display an operator's skill level together with that of a skilled operator or with his/her work data
of the past on a screen for the purpose of comparison, so that the complicated and hard-to-understand
sewing machine operation can be visualized for easier analysis.
(4) Production management function
The production management function displays the target production volume for given working hours and
the actual production volume to notify the operator of a delay or progress of sewing work in real time.
With this function, the operator is able to carry out his/her work while checking his/her work pace. This
enhances his/her motivation to achieve his/her goal, thereby leading to a increase in productivity. In ad-
dition, this function allows early detection of a delay in work making it possible to identify a problem and
take an appropriate measure at an early stage.
