. INTRODUCTION

This Instruction Manual describes JUKI operation panel "IT-100".

Be sure to read "Safety precautions" in the Instruction for the SC-920 (control box) before reading this In-

struction Manual to fully understand them.

In addition, this product is precision equipment. It requires careful handling. Take care not to drop or

roughly handle it to protect against any physical shock.

The operations of the IT-100 operation panel mainly consist of those carried out under the "normal sew-

ing mode" and those under the "information mode." These two modes can be changed over by means of

the information switch .

Information mode

Under this mode, function settings for the production support function are carried out and the sewing

machine operation is set/checked.

Refer to

"$. INFORMATION"

for how to operate the operation panel under the information mode.

Normal sewing mode

Under this mode, the sewing machine performs sewing. The sewing screen differs on a model-by-model basis. It is possible to use the IT-100 by changing

over the screen, with the Screen changeover switch , between the sewing screen and the production support function screen on which the production support operation is enabled.

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 efciency 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 efciency-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 enable 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 distribution 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 specied 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 addition, 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.

. How to set the working time and resting time

On the assumption that one sewing machine is used by the operators working the shift or for sewing two or more different sewing items, three different daily

working conditions (working hours and total production volume) be set. The working conditions set in this step can be invoked on the production

management screen under the normal sewing mode. This eliminates re-setting of detailed working conditions at the shift time or the sewing item changing.

The starting/nishing times of work and the resting time of day are set. The working time period can be set more nely with working time and resting time each of

which can be set to three different values.

4. HOW TO OPERATE THE COMMON FUNCTIONS

The common functions are operated in the same way regardless of the model of sewing machine. (The

screen display varies depending on the model of sewing machine.)

4-1. Bobbin counter

The number of stitches sewn by the sewing machine is detected. The detected number of stitches is decremented from the preset counter value (in units of the number of stitches preset using function setting No. 7 "Unit of bobbin thread counting down." When the counter value changes from the positive value to the negative value (...→ 1 → 0 → -1), the buzzer sounds (3

sets of two consecutive blips) and the notication is shown on the popup window to alert the operator to change the bobbin.

1) Press counter/speed changeover switch change over the screen to the counter screen. Press switch 2 to select the bobbin counter. Then, press counter reset switch 3 to return the bobbin counter display to the initial set value (set value at the time of delivery is "0").

The bobbin thread counter cannot be reset during sewing. In this case, make the thread trimmer actuate once.

Initial value on the bobbin thread counter

for reference

3) Once the initial value is specied, start the sewing machine.

4) When a minus value is shown on the counter, the buzzer peeps three times and the pop-up display appears, replace the bobbin thread.

2) Set an initial value using counter value setting switches

and 5.

The table below gives the initial setting values for reference when the bobbin is wound with thread to the extent that the pinhole in the outside of the bobbin case is

reached as shown in the gure on the left side.

(stitch length : 3 mm)

Thread tension rate 100 %

* The aforementioned values actually vary depending on

the material thickness and sewing speed. Adjustment is necessary according to the conditions of use.

Bobbin thread replacement warning pop-up

5) After the bobbin thread has been properly replaced, press counter reset switch 3 to return the value on the bobbin thread counter to the initial value. Now, re-start the sewing machine.

6) If the remaining amount of bobbin thread is excessive or the bobbin thread runs out before the bobbin thread counter indicates a minus value, adjust the initial value appropriately using counter value setting switches 4 and 5.

If the remaining amount of bobbin thread is excessive ..... Increase the initial value using the “+” switch.

If the remaining amount of bobbin thread is insufcient .... Decrease the initial value using “–” switch.

1. The remaining amount of thread may vary depending on how the thread is wound on the bobbin and the material thickness. It is therefore better to set the remaining amount of thread with a slight allowance.

2. If the bobbin thread counter is used in combination with the bobbin thread remaining amount detecting device, the bobbin thread counter indicates the number of detections of the bobbin thread remaining amount detecting device. So, be sure to use the device after carefully reading the Instruction Manual for the bobbin thread remaining amount detecting device.

4-5. Needle up/down compensation switch

Every t i me nee d l e up/d o wn comp e nsatio n switch 1 is pressed, the needle goes up when it is in its lowest position or comes down when it is in its highest position. This compensates the stitch by a half of the predetermined stitch length.

Note, however, that the machine does not run continuously at a low speed even if you keep the switch held pressed. Also, note that the needle up/down compensation switch is inoperative after turning the handwheel by hand. Thread trimming is operative only at the time of stitch compensation after depressing the front part of the pedal once.

5-3. Operating the pitch time monitor screen

The pitch time monitor screen has two different screens, i.e., the screen No. 1 that displays the production

volume and pitch time as a graph, and the screen No. 2 on which the graph-related setting is carried out.

(1) Pitch time monitor screen No. 1

The pitch time monitor screen No. 1 is operated under two different modes, i.e., the production volume graph mode for displaying the transition of the production volume with time, and the pitch time graph mode for displaying the distribution and variation of pitch time (operation time) per sewing item. The sewing work status can be checked by changing over the mode between these two on the pitch time monitor screen No. 2.

(1)-1 Production volume graph mode

A graph vertical axis of which represents the production volume and horizontal axis of which represents the working time of day is displayed. With this graph, the production status over a long period of time can be checked and the time period where a problem occurs can be found.

In addition, the production volume in the section specied with the cursor

5-4. Operating the sewing recorder

The sewing recorder screen consists of two different screens; i.e., the screen No. 1 on which the sewing speed and the thread trimming timing are continuously measured and displayed as a line graph and the screen No. 2 on which the sewing machine operation rate/average sewing speed are displayed and setting of the graph display on the screen No. 1 carried out.

(1) Sewing recorder screen No. 1

On the sewing recorder screen No. 1, the operator's sewing performance is displayed by means of the line graph showing the sewing speed and the time. Based on the graph, the sewing skill level check and training of the sewing machine operator can be carried out. Two different data can be indicated on the graph as data No. 1 and data No. 2. This means that the target operator's data can be shown together with data on a highly skilled operator's work or the data on his/her work in the past for the purpose of comparison. The comparison through visualization enables easy analysis of complicated and hard-to-understand sewing machine operation.
