Module Production] group box.

9. Click [Next] when completed making settings.

10.Specify the optimization options you want to use. For details on the settings refer to the

table below. Select the check box for [Performs basic head optimization] to have the

optimizer decide the head setup for the modules.

Note: Head optimization does not change the heads on modules with OF, F04, or G04 heads nor

can it allot these heads. These are special heads and if they are being used, then they

should be specified in their modules in the job before using NXT Multi Machine Optimizer.

Setting Description

Optimize For Single

Module Production

This specifies whether or not paired module production is

used for panels between 250 and 305 in length. This

setting has no bearing for panels outside of this range. If

this is not selected and the panel size is within the range,

the M3 modules are automatically paired for paired

production. If this is selected and the panel size is within

the range, the M3 modules are not paired. For panels

smaller than the range, M3 modules are never paired. For

panels larger than the range, M3 modules are always

paired.

Optimize Panel

Stopping Position

Offset

This specifies whether or not the panel stopping position is

optimized for paired module production. This is only for M3

modules when they are performing paired module

production.

Allocate Parts To

M6 Module

This specifies whether or not to allocate parts that are in

the head interference area during paired module

production to M6 modules if possible. By selecting this

option, head waiting time during paired module production

is reduced. However, more parts are assigned to the M6

module.

Setting Description

Reallocate feeders If this option is selected, then feeders that have a variable

status can be moved or even deleted if they are not needed

during optimization. If this option is not selected, then

already existing feeders cannot be moved or deleted and

any newly required feeders can be set in empty slots only.

Allocate parts with

excessive

sequences to

multiple modules

This specifies whether or not parts with many placements

will be broken up into multiple feeders and set into different

modules. If this is selected, parts with many placements

can be set in multiple feeders and placed on multiple

modules if possible.

Divide parts on

fixed feeders

Specify whether to reallocate parts on fixed feeders when

[Allocate parts with excessive sequences to multiple

modules] is selected. When this is selected, parts on fixed

feeders can be allocated to other modules to reduce cycle

time.

11.If basic head optimization was specified, then a step to specify the number of heads

available for each type is displayed. Specify the number of heads for each type of head

and then click [Next]. If head optimization was not specified then the next step is

displayed.

Use current feeder

setup

When the [Reallocate Feeders] option is selected, this

specifies whether or not the current feeder setup will be

changed or not. If this is not selected and the [Reallocate

Feeders] option is selected, then the current feeder

positions and settings are completely ignored and all

feeders are redistributed. If there are variable status

feeders that are not being used in the current job in the

feeder setup, these feeders are removed.

Optimize insert

order only

When this is not selected, insert order, feeders, head

setup, nozzle stations and other items can be optimized/

changed during optimization. Only the insert order is

changed during optimization when this is selected.

Optimize nozzle

station

This specifies whether the nozzle allocation should be

optimized or not. If this is selected, the nozzles in the

nozzle station will be changed to be "optimized" for

production. If this is not selected, then optimization is

performed without changing the nozzle setup.

Nozzle station

nozzle allocation

method

Specify the nozzle station nozzle arrangement method.

"Minimum" arranges for the minimum number nozzles

required by the head. "Maximum" arranges for the

maximum number of nozzles allowable in the station.

Optimizer Type This setting specifies the level of optimization to be

performed. "Speed" performs optimization with a priority

on achieving a relatively fast cycle time and processing is

performed quickly. "Optimal" performs optimization with a

priority on achieving the fastest cycle time and processing

takes longer. "Time Limit" performs processing the same

as "Optimal" but within a specified time limit.

Processing time

limit

This only displays if [Optimizer Type] is set to "Time Limit".

This specifies the time limit in minutes that the optimizer

has to complete processing.

Used feeder type Specify the whether of not reel holders are on the feeders.

If set to "Reel holder", the optimizer positions feeders in the

feeder setup considering that the feeders have reel

holders. If this is set to "Reel holder-E", the optimizer

positions feeders in the feeder setup considering that

feeders have no reel holders and a bucket type feeder

pallet is used.

Performs basic

head optimization

When this is selected, the setup of the heads is considered

during optimization and the heads/nozzle stations used are

changed to best suit the job. The GL, F04, G04 and OF

heads are not considered when using this option and will

not be moved, added, or deleted because these are

special head types. If using these head types, manually

set them in the job before optimizing. In addition, the

quantity and head types available for optimization are

specified in the next step when this option is selected.

When this option is not selected, step 4 is skipped.

Note: If the value is left at 0, then the optimizer will considers there to be no limit to the number of

heads for that type. If a head type is not available, then clear the check box for the head

type.

12.The current configuration for the machines is displayed. Click [Next] to start the line

balance/optimization process.

13.The line optimization process is started and the results are displayed. In the first stage

of optimization/line balancing, the optimizer loads and parts are assigned to the various

modules. At this do not normally cancel the optimization as the assignment of the parts

is not complete and there many be unassigned parts. When the text "Optimization will

continue until cancelled", then the process can be cancelled with no problems other than

optimization has not fully been completed. Optimization continues until the optimizer

decides on the best scenario.

14.Click [Save] to save the result of the optimization back to the job. If this step is not

performed, then none of the results of the optimization are reflected in the job.

15.After saving the results, then click [Cancel] to close the wizard.

3.6.3 Dual job optimizing

In order to perform dual job optimization, it is necessary to have the optional software, NXT

Dual Production Optimizer, installed on the computer.

1. Ensure that both jobs for which optimization is to be performed are complete in the terms

that they can be used to produce panels.

2. Click the [Start] button, point to [Programs] > [Fuji Flexa] and then click [NXT Dual

Production Optimizer]. The first step of the wizard displays.

3. Specify whether optimization to to be performed between two different jobs or for both

panel sides for one job by selecting the appropriate option.

4. After selecting the desired job option, click the button with the three periods to the right

of the job text box for lane 1. A dialog box displays the available jobs.

5. Select the desired job to be produced using lane 1 and click [OK]. The name of the job

then displays in the job text box.

Note: If an error occurs about not being able to open the job, ensure that the job is not currently

opened. Opened jobs cannot be selected.

6. Specify the panel side for the selected job by using the drop-down list to the left of the

button.

7. If two separate jobs are to be optimized, then repeat steps 4 to 6 for Lane 2.

8. Click [Next].

9. Select the machine to be optimized.

10.Select any desired optimization options and clear any unwanted options.

Setting Description

Optimizes only the

designated module

When [Reallocate Feeders] is not selected, this setting is

enabled. When selected, only optimization for the modules

selected from the list below this setting is performed.

When this is not selected, optimization for all modules is

performed.
