7.7 Optimize

What is the Optimize?

This application divides a production program data created with the Program Editor and assigns

these divided data to machines configuring a line so that the production time of each machine can

be almost the same (that is, creates divided files of a production program). It also optimizes the

feeder attachment position and the component pick-up/placement order. The production time of

machines is called “line balance.” The less the production times of all machines deviates, the

better the line balance becomes.

In addition, the system generates a division file for an inspection machine/printer based on data

set in the station data.

* The production times may not become equal to one another depending on the number of nozzles,

the number of feeders and/or the number of component reels that can be used for PWB produc-

tion. The optimization result varies greatly depending on the option settings or the settings of

components to be supplied.

7.7.1 Optimization Types

Optimization item

Summary of the function

Assignments

Divides program data created with the Program Editor and assigns di-

vided data to each machine.

Optimization for

each machine

Feeder as-

signment

Outputs the optimal feeder attachment position for program data divided

and assigned to each machine.

Sort placement

order

Outputs the optimal component pick-up/placement order for output of

the feeder assignment

Nozzle assign-

ment

Outputs the optimal nozzle assignment for the component pick-up and

placement order.

Station data

Outputs data specified in the station data as data for an inspection

machine/printer.

Tact simulator Simulates the production time of each machine based on the results of

the “Assignments,” “Feeder assignment” and “Sort placement order.”

Line balancer

Moves data among machines if the line balance is found to be bad as a

result of tact (cycle time) simulation.

7.7.2 Starting Up the Optimize

Optimize option setting area

Option selecting area

The <Default> button disables the setting(s) you

changed, and restores them to the standard setting(s)

(initial setting(s) of the MI Line Optimizer).

The <Save as default> button registers the changed

settings as the initial values, and displays the

changed settings at first when you start up the opti-

mization function next time.

This <Go> button optimizes program data under the specified conditions.

7.7.4 How to Operate the Optimization Options

Assignments option

Figure 7.7-3 “Assignments” option

(1) Component Data

When there are two or more feeders for the same component type, specify whether to assign

components to only one feeder or two or more feeders.

This is an ineffective option when the number of machines is 1.

(2) Nozzle

Specify which nozzle assignment is to be used, the nozzle assignment made with the

“Shopfloor Setup” or the optimized nozzle assignment.

1) Line

◆

Auto arrange nozzles:

Ignores the setting of the permanent nozzles made with the Shopfloor Setup and opti-

mizes the nozzle assignment. Although the production cycle time becomes shorter, you

have to change the settings of the machine and it takes longer time to set up the machine.

Select this option for mass production of PWBs.

◆ Auto arrange empty nozzle positions:

Uses the permanent nozzles set with the Shopfloor Setup as they are, and assigns the

applicable nozzles to the empty positions of the ATC when there are still nozzles you can

use.

◆ Use setup nozzles:

Uses only the permanent nozzles set with the Shopfloor Setup. Since it does not take

any time to set up the machine, select this radio button for small production of variety of

PWB types.
