III – 5. Advice for cycle time optimalization

The IMM cycle time is often greater than the robot’s one. Even so, it is always interesting to reduce it,

especially the IMM immobilization time.

The IMM immobilization time is the length of time that separates :

 the mould access authorization that the IMM gives to the robot : Mould Open (MO) or

Partial Opening Reached (OPA) signal

from

 the Machine Cycle Validation (VCM) that the robot gives to the IMM to authorize the

fabrication of a new part.

To reduce the IMM immobilization time, you can use a certain number of instructions and options offered

by Sepro, and several rules must be respected to guarantee the equipment safety and the reliability of the

cycle.

 The cycle time reduction MUST NEVER increase the number of incidents. In this case, the

time lost restarting after an incident cancels the few tenths of a second gained during

optimalization.

 The paths obtained after optimalization must not contain a risk of collision if, for one reason

or another, a part of the movement slows down.

For example, when you switch to Step by Step mode :

path obtained in

automatic mode

path obtained in Step

by Step mode

The robot arm must be stopped as close as possible to the mould when waiting for the latter to open. The

IMM cycle must be restarted as soon as possible. To ensure this, the Out of Mould Area (ZHM) cam is

adjusted as correctly as possible : the lowest position of the robot’s arm that allows the mould to open and

close without colliding with the robot’s gripper head.

The Sepro programming instructions used for the cycle time optimalization are imprecise (IMP) and the

master movement (MASTER). Their use is described in chapters IV – 4. 4. and IV – 4. 5. page 47.

Using these two tools enables you :

 to round the paths as the movement follow each other

 to mask the part demoulding movements (ejectors and/or core pullers) by doing them

during the robot’s movements.
