9.24.14 Night Shift Activities

Worked on conveyor for Mp#27. I added some pvcc stock to prevent small parts and runners from getting underneath the side rails. This has been occurring frequently jamming the conveyor belt. There are two more like it that also need the same modifications.

Mp#21- Checked out the robot conveyor wiring. I had already wired it correctly but it wasn't operating because the relay base was bad. I replaced it with Allen-Bradley and checked for proper operation.

Mp#4- Finished wiring changes to cores and repaired some damaged wiring while I was there.

Mp#5- Repaired some broken wires on the mold. They were using wire nuts to hold switch wires together on the cylinder that must be removed each time the tool is pulled or set. I added quick connect plugs.

Mp#14- Finished installation of service call light. We still need to order four more for the added presses.

Have a great day!

Mp#28-
Worked on the granulator. The clasps that keep the side clean out door closed were evidently damaged and needed replaced. Went ahead and replaced gasket on the door also. Tightened loose screws on everything and replaced those which were missing. The belts looked fine and the size number is shown in the image attached here for future reference.

Mp#8-
We had a temperature controller issue on one of the old the Nissei ASE machines. There is a contact that must close on barrel heater zone 1 to allow the screw to rotate. It is there to prevent a cold start up but- it was up to temperature an d not closing internally.  We swapped it with another controller and it corrected the issue.

At one time Mark and I had started replacing the old analog controllers with newer digital upgrades but that got pushed back with the TTI machines.

Mp#10-
NISSEI alarm "1216"
Ejectors would not work, even though core set/pull operating correctly.
I found the problem related to the core sequence settings and the clamp position switch locations. (Adjustment)
On these older machines, it is critical that the mold correctly make the intermediate position correctly.
In sequence 3, that position is where the mold will stop and pull cores and then open to the full position, where it will eject parts...if it does not see the position switches correctly,  it will just open all the way up and then fault out.

Mp#0-
Had some issues with input 40 not reading because EOAT was not retracting brackets correctly. Kenny and I found bad solenoid valve and swapped it with a spare temporarily until we can get a replacement.

Mp#1-
Techs accidentally overtravelled the Z axis and couldn't get it to power back up. We ended up manually activating the brake on the X axis and moved it out of the mold area. It then allowed us to power it up and move it from the overtravelled condition.

Mp#2-
Finished wiring 24 common circuit into core switch receptacles. Only Mp#4 and #5 remain to be done as scheduling permits.

Began construction on another Corlogix box. I will check with MRO to see what parts are available and give Kenny a list for the remainder of items needed.

Have a great day!

9.11.14 Night shift activities

Marty and Sean wired in service call lights on Mp#7,9,18,20, and 21. We also mounted boxes on several others.

Mp#0, 1, 27, and 28 will need new call lights purchased for them.

Roy Smith, Cory Lemmons, and Mike Sells worked on PM's for the presses scheduled to run on Monday.

We all worked from 3p.m. until 11p.m. with no lunch taken (8hrs).
