22.If performing paired module production, then specify the settings you want to use below.

23.Click [Next] to display the next step.

24.Select the check boxes next to feeders and nozzles that are available. Clear the check

boxes next to any feeders or nozzles that are not available.

25.Click [Next] to display the final step.

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

will 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.

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.

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.

Setting Description

Optimize panel

stopping position

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.

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.

Allocate parts in the

interference area to

M6 modules

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.

26.Click [Next] to start the NXT Multi Job Line Balancer using the current settings. To

review the settings, click [Back]. The line balancing process is started and the results

are displayed. Line balancing continues until the Line Balancer decides on the best

scenario.

27.Click [Save] to save the result of the line balancing back to the job. If this step is not

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

28.After saving the results, then click [Exit] to close the wizard.

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.
