3.6 Optimizing

After balancing the line, the parts need to be distributed to the different modules and the

sequences for each module need to be arranged in the optimum order to minimize cycle

time. The optimizer is used to arrange the sequences in the best order. In addition to the

optimizer within Job Builder, there is another optional optimizer for optimizing different jobs

or sides. NXT Dual Production Optimizer is capable of optimizing two different jobs to run

on different lanes or two sides of a panel using two different lanes. For procedures on using

this optimizer, refer to the section Dual job optimizing.

3.6.1 Optimizing in Job Builder

The following procedures are used for optimizing one job only.

1. Select [Optimize] from the [Tools] menu to display the [Optimize Options] dialog box.

2. To optimize the feeder arrangement, select the [Allocate feeders] option. After

specifying the desired settings, click [OK] to display the [Select Machine] dialog box.

3. Select the desired machines, and click [OK].

4. Click [Yes] in the confirmation dialog box to confirm that optimization is to be performed

for the selected machines.

5. The [Optimize] dialog box displays. In this dialog box, the status of the optimization

process displays along with any errors. If any errors occur, click [Error Details] to display

further details. Click [Close] when the optimization process is complete.

Note: Once the job has been optimized, it can be transmitted to the NXT machine. It is not

necessary to generate recipes for the NXT.

3.6.2 NXT Multi Machine Optimizer

Generally, an NXT line consists of "one" NXT machine (made up of multiple bases). With

this configuration, line balancing is very simple and all of the parts are simply assigned to

the NXT machine. The parts assigned to the various modules is optimized and rearranged

during the optimization process. However, if the NXT line is comprised of multiple NXT

"machines", then use this software to line balance and optimize the job.

Job condition before using NXT Multi Machine Optimizer

The job must be in the condition below before using this software.

• The line must be already selected in the job.

• The basic configuration of the line must already be set (number and type of

modules and if not doing head or nozzle optimization, the heads and nozzles for

each module).

• All of the marks to be used must be assigned to the machines.

• All of the parts to be placed must be assigned to at least one machine. (This

software does not assign unassigned parts; it just moves assigned parts from

one machine to another.)

Procedure

1. Click the [Start] button, point to [Programs] > [Fuji Flexa] > [Optimizer] and then click

[NXT Multi Machine Optimizer]. 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 [Optimizer]

section of the icon bar.

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

3. Click the button with the three dots in the [Job] group box to display a list of the available

jobs.

4. Select the location for the job in the left pane and then double-click the job you want to

line balance and optimize to select it. The job is opened and the name displays in the

text box.

Note: The job cannot be opened if another program already has it opened.

5. Select the side of the panel to be line balanced and optimized.

6. Select any other options you want to use in this step and then click [Next].

7. Specify the settings for the conveyor in the [Conveyor Settings] group box.

8. If performing paired module production, then specify the desired settings in the [Paired

Setting Description

Optimizes the entire

NXT line

When selected, the entire NXT line is line balanced and

optimized. If option is not selected, then only the machine

selected in the [Line Configuration] list is optimized (if no

machines are selected, then the first machine is

automatically selected).

Support XPF Select this option if there are XPF machines in the line with

the NXT. By selecting this, the XPF will be considered

during optimization of the NXT machines.

Setting Description

Conveyor Mode This setting specifies the panel conveyance mode to be

used for production for determining optimization.

Board Flow This specifies the direction in which the panels flow

through the machine. This settings does not actually

control the direction in the machine but is used for job

related processing in Fuji Flexa.

Lane 2 reference

rail setting

This specifies whether or not the reference rail for the

second lane can move to different positions. If this is set to

"Fixed" the reference rail cannot move to different positions

and a setting must be specified for [Interval between lane

1 and 2 (mm)].

Interval between

lane 1 and 2 (mm)

This setting is only available when the setting for [Lane 2

reference rail setting] is "Fixed". This setting specifies the

location at which the reference rail for lane 2 will be fixed.

Target Conveyor This specifies the target lane on which the job will be

optimized. If set to "Lane 1", then the job is optimized with

the premise that the panels are to be loaded on lane 1.

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.
