" C " Shift

  MP5    Installed  new 21/15 gal. pump ;  still not working. The variable volume pump is bad – no pressure @ test port & no sled movement.

            They are going to hang the other base plate mold in MP6, so we’re OK on parts.

 

MP21    The DME on the nozzle was left on , ( no mold in press )  & material blew out on moving platen. Not sure when this happened- wasn”t  today.

            I turned DME off & cleaned the platen.

 

I checked , cleaned & lubed tie bars – MP13 thru 25

More from " C " Shift - ( Friday )

       MP -13      Just before shift change , 5:30 pm,  they found a blow-back ¾  of the barrel was covered on the top side ( DELRIN )

                      I cleaned it off ,replaced 3 nozzle bands, & rewired 2 barrel bands. Luckily the connectors for the barrel heaters were on the bottom & weren’t

                      covered  up  with plastic.

                      The nozzle was loose, I turned it by hand.

RE:

Worked on number 22 robot tonight. It alarms while stacking the parts on the belt during the down stroke at random pack numbers. The alarm is displayed as a Y inverter fault and it states the Y speed cannot be controlled. I changed out the y-axis encoder, switched the Y and Z inverter cards, and checked all the connections to the circuit board under the x-axis cover. I checked the different voltages on the main transformer to make sure they were within tolerance and monitored the inverter power supply voltage while the robot was operating and everything seemed ok. I tried changing the y-axis pack speed to different values also.

8.15.09 night shift---Sean

Put a tool arm and program on the Wittman tonight. I worked with the techs so they could do hands on with it so they could understand how to make changes to positions and speeds or call up existing programs.(at their request).

Should be ready to go. We also added commentary to the program and saved it by mold number.

Had a bad locator ring in #23. I pressed it back straight and turned the I.D. back so it would work again.

The robot on #5 had some incidents of stopping over the conveyor after dropping parts.

It would simply reset and rehome.

I am guessing a potential encoder error. Has not stopped since 11 pm so ???

I'll be back on saturday, Call if you need me.

12.14.09 night shift...Sean

Worked on moving stuff out of repair area. Green-tagged 3 or 4 color pumps after checking them out.

I Re-did the float switch on the leak reservoir on MP#17 and put cover back on.

Marty had asked me about the "transfer velocity" setpoint that shows up on press#3 but not on #2. I looked through both control books to see if there was a convec to turn on that would make it appear on screen but did not find anything. Both books never made mention of that setting. The 486C control has it but the 486 does not so I am guessing that it is simply in the screenware program?

I called the Milacron after hours number to see what the deal was but the guy acted like he didn't know what I was talking about.

I am not sure that it is even needed but would like to know.

The screw on MP3 was wrapped with plastic but it was only near the back so we didn't have to pull it. The robot on MP4 lost communication error twice and the screen would freeze up. In order to reset it we had to power down the robot. The nozzle on MP5 caught on fire due to the sled being misaligned ,plastic bleeding off, and shorting some wires out. I replaced the nozzle band, thermocouple, and realigned the sled.

Sunday 12-13-09 A Shift

Saturday we kept getting a Y inverter fault again on the Wittman, so today I jumped out the Y Inverter Fault Monitoring Input to the control in the cabinet.  After that I dry cycled the robot for 4 hours with no problem.
If there is a minor problem still, the control will not know it and it should continue to run. If there is a real major problem, the robot will hopefully run long enough for us to get more clues to fixing the problem.
Call with any questions.

Surge bins

The surge bins ran out of material tonight which was due to bin #1 material hose having holes all in it. We replaced the hose and checked the others which were all ok. Also dryer 11 on MP16 blew a fuse around 6 p.m. Day shift said it blew one on them too. It ran the rest of the night with no more problems.
