#10 robot was stopping over the conveyor and screen was displaying
"robot not on". It would not power up at all. Got in the cabinet and traced down the mcr circuit to one of the NC switches on the y or z axis. Replaced the Y axis reference switch and had no further trouble from it.

Pulled hoses from eagle top cover tool that is going out today for engineering changes. I made a detailed drawing of hoses but they are still together in one bunch and is fairly self explained when looking at them. They are in a blue tote.

Finished putting up the signs for the disconnect locations at machines.
If there are any problems with them we'll be glad to make changes as needed.

GR-20 : Replaced start push button. Replaced broken caster with a used salvaged one. Put the panel screws back on it. Green tagged it after starting it and checking operation.

The conveyors in the shop are 200vac. They are rated at 25watts. The star robots have a maximum requirement of 500va (or.55%x500=roughly 275 watts) and the transformer is only rated for 500va...so they could only use them if they do not run the robot at the same time.

Call if there are any questions.

Mp#22- set it up on the robot, made some program changes and modified EOAT.
Mp#21- After resetting clamp by the book instructions it worked alright.

Did some minor mold repair work for moldsetter.

Hung about half of the disconnect signs. Will finish tonight.

Mp#3- someone ran the extruder with the sled forward and created a nozzle mess. Replaced both bands and thermocouple.

Also 3, the motor keeps stopping, about 30 times last night.

Need to layout a plan for that, it has become a production problem now.

Call if there are any questions.

   MP-17   Vacuumed oil off of clamp end deck; will try & get back to this one later. Needs “ O “ rings changed on directional valves.

 

  MP-5   Made new belt for extruder rpm meter so Josh could recalibrate.

 

  MP-7   No clamp movement – One of the input plugs was pulled out in robot cabinet.

 

  MP-22   Made new end of arm tool for the bag stiffener.

 

  MP-7   Machine stopped in cycle- error code 5202 – back door came open.

Got MP2 running today, but the eject option I tried to add never did work.  The software did not want to cooperate.  How it is running now is that I have the ball valves cracked a little and I’m just reading the butterfly position, not the switches on the mold.  I also turned on the core 2 option, but I never tried it out.  They needed parts and we’ll just deal with it later.

Robot on MP7 is ready.  X axis was not reading position.  Gary swapped out the encoder with the new style and also ran a new cable down to the plug on the beam.  It still would not work and we ended up finding pin 1 loose in the plug.  The plastic is wore out and the pin does not want to stay, so right now we just forced it in there and wire tied it good.  If you have problems with X axis in the future, check pin 1 on the encoder plug first.

MP10 bowl feeder still needs a little work.  Gary is going to come in for a bit tomorrow and work on it.

 

Thanks

2.14.10 Weekends on nights Sean

Mp#10- parts were not welding the deflector. Double checked the process before i began working on it. It was running at 56 seconds cycle time. Water was partailly shut off, but not all the way. To cut it short, Marty and I adjusted the fixture and just kept working with it until they were welding good again.

Worked on the 900 Yushin sprue picker. I wired up the other interface box using the 200vac transformer because the print was calling for that circuit box. It came up but indicated E-stop faults which were from a blown fuse. Changed fuse out, got it up to a "kick cyclinder input error" .
It probably has a short in either the sensor or the pendant because it keeps blowing the fuse. If it turns out to be the pendant then I can still change out the board/pendant with one of the others.

Mp#2- I attempted to plumb in the hydraulics on Core #2 . The pressure line is tapped into MX2 feeding off P1/P3 circuit. It has NOT been checked yet, still need to turn on the Core 2 convecs/ options etc. and set up pressures and flow controls etc. I have some questions for Josh about this when I come in next or can call me, etc.

Went through the trailor and tried to straighten up etc. Moved the 3 small conveyors into the shop and let the process techs know that they can use them to draw runners out from under presses where needed. No takers yet.

The Pump motor on #3 is limping along for now. I understand that Josh is checking on getting it rewound, etc.

Call if i am needed. Next week is my short week and will be glad to come in and assist at short notice. Thanks.

 MP-1   Finished vacuuming out tanks.  Emptied oil vac.

 

 Potter  wants more of the trays made for the tall conveyors. I need to order material to complete these.

 

 At 12:30  the security guard told me one of the units in life test had fallen & was hung up between the test platforms. I shut it down , unplugged & unbolted  the unit ,

     & set it on the floor. I restarted the tester.
