Specifying in MEdit

1. Open the job in MEdit. (Refer to "5. Editing Jobs on the Machine (MEdit)" for details.)

2. Select the [Panel] tab. Input the maximum warpage in the [Max Panel Warpage] field of

the [Properties] pane.

• Setting range: 0.00 to 2.00 mm, default value: 0.00 mm (placement movement is not

changed)

Important points

• There are cases in which placement may not occur properly if the warpage set

in the job is less than the actual warpage.

• Even when also using the panel height detection function, the result from that

function does not influence head speed change height here.

3.5 Line Balancing

Line balance is performed to balance the workload of each machine as much as possible.

Due to the unique nature of putting multiple NXT bases together to create one large NXT

machine, the concept of line balancing has greatly changed for lines with only NXT bases.

For line with only NXT bases made up into one NXT machine, all parts will be simply

assigned to the NXT machine. This will still be an important step for lines with multiple

machines though. However, there is a special outside line balancer/optimizer available for

multi-machine NXT lines called NXT Multi Machine Optimizer. Refer to the Optimizing

section for procedures on using this software to line balance/optimize.

Note: This means that if a NXT machine is the only machine in a line then the assign part

command can be used to simply assign all of the parts to the NXT machine.

3.5.1 Line balancing in Job Builder

Follow the procedures below to line balance using the function in Job Builder.

1. Select [Line Balance] from the [Tools] menu and the [Line Balancer Options] dialog box

displays.

2. Select the appropriate option and click [Start] to start the line balancing process and the

[Line Balancer] dialog box displays with the current status of the balancing process. If

the option “Do not use current feeder allocation” is used, then all of the parts are

assigned to the different machine without considering any parts already set in the feeder

setups. If the option “Use current feeder allocation” is selected, then parts are assigned

to machines while considering any parts already present in the feeder setup. This

means that if a part is already in the feeder setup for a machine, then the matching part

is possibly assigned to that machine.

3. If there are any errors, click [Error Details] to view the errors. Once completed, click

[Close] to close the dialog box. If there were errors, note what the errors were and

correct them and then rebalance the line again.

3.5.2 NXT Multi Job Line Balancer (option)

The NXT Multi Job Line Balancer is exclusively for creating feeder setups that contribute to

the reduction of feeder changeover time for NXT machines. This software is an option and

requires a license in order to use it.

Important points to note before using the NXT Multi Job Line Balancer.

Be sure to note the following points.

• Part data on the part data server is used by this software. Therefore, copy the

part data to be used from the jobs to the server if they are not already on the part

data server.

• Select a line that includes an NXT machine type for all jobs being used in the

NXT Multi Job Line Balancer.

• The NXT Multi Job Line Balancer does not change parts assignments. If

necessary, make these settings before processing.

Procedure

1. Click the [Start] button, point to [Programs] > [Fuji Flexa] > [Multi Job Line Balancer] and

then click [NXT MultiJob LineBalancer]. The wizard starts and the first step displays.

Note: It is possible to start this wizard from Director by clicking the icon for it in the

[MultiJobLineBalancer] section of the icon bar.

2. Click [Next] to proceed to the next step.

3. Click [Add] and the [Select Job] dialog box displays.

4. Using the dialog box, locate and select the jobs on which to perform multi job line

balancing.

Note: Hold down Ctrl when selecting multiple jobs.

5. Select the side of the panel to be line balanced and then click [OK] in the dialog box that

is displayed.

Note: It is possible to change the side after this step by right-clicking the job name in the list and

then specifying the side in the shortcut menu.

6. Continue adding jobs until all of the jobs you want to line balance have been specified.

7. If you want to specify production quantity settings for jobs, right-click the job name and

then select [Enter the production quantity] and then specify the production quantity in

the dialog box and click [OK].

8. If you want to prioritize production for a side of the panel in a job, then right-click the job

name and then specify the side from [Prioritizing Production].

9. Once all of the jobs and desired settings have been specified, click [Next] to display Step

10.Click the [...] button and specify the name of the job to be used for the line/feeder setup.

11.In the [Feeder allocation setting] group box, select the feeder allocation method to be

used.

12.In the [Settings] group box, select the appropriate setting.

Setting Description

Consider the

allocation of all

feeders

All of the variable status feeders for the job in the [Job used

for line or feeder setup] setting are not moved from their

position as much as possible (a feeder will be altered if

necessary for other jobs). Fixed and reserved feeder

positions from this job cannot be altered.

Consider the

allocation of

Reserved and Fixed

feeders only

Fixed and reserved feeder positions for the job in the [Job

used for line or feeder setup] setting cannot be altered, but

the variable status feeders can be altered freely.

Setting Description

Group jobs for

batch changeover:

A common feeder allocation for multiple jobs is created and

the jobs are grouped. There are times when multiple

groups are possible. In this case, changeover between

groups occurs but the groups do not share a common

feeder allocation.
