4.4.1.2 Setting the optimization conditions

The optimization result may vary depending on the settings on the “Component supply count”

dialog box described above and those on the “Optimization” dialog box described below. Set

the optimization conditions of a production program only after understanding the descriptions

below well.

When you select the [Optimization] – [Optimization] commands, the “Optim option”

(optimization option) dialog box appears on the screen.

Set the six categories of conditions including the “Assignments” option.

Select this tag to change the screen for the corresponding option.

Option Description

Assignments Specifies the option to be checked with the Optimization utility when it assigns a

nozzle or Pick data.

Area Specifies the area to which a feeder can be assigned.

Place order Specifies the option to be used for changing the component placement order.

Model option Specifies the option unique to the model.

Feeder option Specify the options related to the feeder layout.

This button registers new settings as the initial values.

The new settings will be displayed in the beginning

when the system is booted the next time.

This button invalidates your registered

settings and restores the standard

settings (initial values of the machine).

This buttons executes the

optimization function.

This button stores your settings, and

closes this screen.

(1) “Assignments” option

Set "Nozzle layout" and "Feeder layout" intended for dividing (optimizing) the program data.

1) Nozzle

Select which nozzle layout you want to use, the nozzle layout set on the "Machine setup"

menu or the optimized nozzle layout.

a) Use machine setup nozzle:

The nozzle settings on the "Machine setup" menu are used as they are. The current

nozzle layout can be used as it is. This option does not need any changeover time, and thus

select this option for flexible manufacturing.

b) Auto arrange empty nozzle positions:

The permanent nozzles set on the “Machine setup” menu are used as they are, and the

nozzles required as the result of optimization are assigned to the empty area of the ATC. If

your system has enough nozzles to do this operation, select this option. Note that you

have to change the settings on the “Machine setup” menu to set the additionally assigned

nozzles if you select this option.

c) Auto arrange nozzle.

The nozzle layout is optimized with ignoring the settings of the nozzles made on the

“Machine setup” screen.

In this case, the production tact becomes speedier but nozzle re-layout and machine setup

setting changes are required. Accordingly, preparation may take more time.

d) Rearrange already assigned nozzles

The permanent nozzles set on the “Machine setup” screen are used to optimize the nozzle

layout.

You are supposed to use this setting to rearrange the nozzle layout without changing the

current number of nozzles. Note that preparation may require more time because the

nozzle re-layout and/or change of the settings of the Machine Setup items are (is) required.

2) Pick Data

Specify whether to assign feeders according to a feeder layout specified in the “Side” field

on the “Pick” data screen or optimize the feeder layout with ignoring this layout.

a) Use manual position assignment:

Perform the specified feeder layout as specified and optimize only the feeder layout set to

"Auto selection."

4-132

b) Auto assign all data:

Ignore the specified feeder layout and optimize the whole feeder layout.

Once you execute the optimization function, its result will be reflected in the “Side” filed of

the “Pick” data screen also. To retry optimization from the beginning after data editing is

finished after this, select "Distribute all." To perform additional layout for only changed

portions, select "Distribute items in the "Auto selection" status."

(2) "Area" option

Specify the area for the feeder layout.

The default selecting state and the area you can select vary depending on existence of a “rear

component supply device” option.

Enabled: All buttons from the <Both sides> to <Prf. Rear> can be selected. (Default: <Both

sides>)

Disabled: Only the button <Front> can be selected. (Default: <Front>)

Area

1) Both sides:

Feeders are arranged into the feeder banks of all areas. For ordinary production, select

this. Because there is no limitation on optimization, the layout is advantageous to the tact.

2) Front:

Feeders are arranged in only the feeder bank on the front side.

3) Rear:

Feeders are arranged in only the feeder bank on the rear side.

All feeders can be arranged on only the front side or rear side.

If feeders are provided in the overall change table in advance, the time up to the next start of

production can be shortened. This makes a layout that makes much of the workability. In

case all the number of feeders to be used cannot be put in the bank of one side, this item

cannot be used.

4) Pri: front:

The feeders are arranged giving priority to the feeders on the front side.

5) Pri: rear:

The feeders are arranged giving priority to the feeders on the rear side.
