Storage trailer roll up door

FYI-

 

Ronnie Colson and Jeremy fixed the roll up door to the storage trailer today.  I just wanted to make everyone aware of it before someone tried lifting it with a forklift again.

 

Thanks

MP#10 Robot- was stopping in mold and at part drop. Found a loose sensor connection on the C axis. Tightened it up. No further problems from that, but then an hour later it would stop over the part drop area with parts. I found that the Z position was not going all the way to set point. Noticed that the belt was off track and loose. Adjusted tracking and tightened it up and had no further problems with 10.

Mp#9 Robot- stopped once at 4am and would not home. Powered it down and reset. referenced it and it would try to home after reference but it could not go to Z at mold position (set at 30) because it was already against the back stop (reading 40 as actual value). We jogged it into the mold and aligned it with parts and it appeared that the Z in mold needed to be at 72 at that point. So we changed that value only to 72 and it started running fine until it went down an hour later. Mark and I discussed changing out to the new encoder style on that axis possibly. Also talked to Potter about that too.

Mp#13- Mold setter was having trouble removing mold from machine. we used die bars to pry it out, then next tool wouldn't fit without forcing so we went around the I.D. of locating ring with a die grinder and cleaned it up. Then tool fit good. O.K. to run.

Finished E-stop install on #22 and checked operation of it. Ran the box and flex for #23 but have not tied it in as they were still running the press. I will continue with that and signs tomorrow. Call if there are any questions, I'll be glad to help.

Gary and Mark changed out a bad heater band on MP16, and also found that the zone 1 TC was not pushed in all the way and was heating 70 degrees above set point.

Monday March 1st

Ordered a new rotary encoder for MP25- it should be here tomorrow.  Mark got the one on there to read somewhat, it may be good enough to limp through until the new one comes in.  We were waiting on them to put a mold in there so that we could really test it out.

 

Also, three “new” 2003 model Jet Loaders came in for MP23-MP25.  One of them has a busted up display and no filter, so I will need to order some parts for it.  Collin, see if you can get two of them ready to run.  I will try and get a good manual for them before I leave today.

 

Thanks

Mp#25-
It is down and needs an encoder for the ejectors. They had problems with it after changing the mold and it would not read, I worked on it and got it to read but it would never close the clamp and it would give an alarm like: "confirm setting for ejector bwd limit." I wanted to eliminate that it was n't the limit switch cicuit so I checked the door switch, and ejector back limit switch jumper and cable.(was fine). I spoke with Mark and gave him the Encoder information and model number.

Made EOAT for the Edge top cover on #11.

Got the signs turned around for the Machine Disconnect locations.

I am sending an email to Jerome asking for some time to get leaks fixed on press# 17.

Call if there are any questions.

MP-16  Tech said barrel heats were running too high.  I checked heaters, contacts, T.C. connections,& cables. Everything checked OK.  The heat profile was 500 to

       535. ( Nylon )   For some reason, we had to run the heats 50 to 55 degrees under & parts ran fine.

 

MP- 17  Mold 74005-01 broke a pin “ again “.  I found the thin switch had been wired N/C.  I changed it & Gill repaired the mold. It should be back in & running

       Before the end of the shift.

 

MP-21   I vacuumed up oil & cleaned around press.

 

DR-23  I put this dryer on the mezz. In place of  DR-19 . We need to order large bed gear for DR-19    Conair part #  183875

 MP- 13 Eject. cylinder bolts broke. Replaced.

 

Dryer- 19  Turntable motor mounts broke & large drive gear stripped. No new gears in stock. Will order more gears Monday.

 

MP- 1  Mark finished pulling valves – we put the frame & covers back on. I should be ready to go .

 

MP- 25  Ejector not working -  Tech said he wiggled the plug on the eject. transducer & it broke off. I was able to straighten the pins enough to plug it back in &

         tape it up. The end that broke off was on transducer. We will have to order a new one to fix it properly.

 

We checked the oil storage building, & the drums had not been emptied, so we loaded four empty drums on a spill pallet & brought them inside.

DR26- repaired the carousel position switch with new screws, no further problems with it.

Gr13- repaired hinge pin, made a new one.

Mp#3- screw was wrapped with plastic and it would not build consistent shot.(kept stopping). Jacked up the barrel heats to 550 and let it soak for about 45 minutes then ran a bunch of clear PC regrind purge and compound through it until it was shiny clean. Ran great the rest of the night.

Mp#2- was down so I checked the core 2 circuit, at first it would not work, then I moved the pressure line to the P1 circuit and it had 2000 psi. Checked it with the test rig that was in the shop and it worked fine. O.K. to run.
Also on 2, I cleaned up the oil that was in the floor there, I couldn't really tell where it was coming from, but it was under the mold area mostly and appeared to have dripped down... was there a leaky mold on A or B shift?

Started swapping orientation of the U-bolts on the disconnect signs, should be finished by this weekend.
Did we decide what to do with the 200volt conveyors in the shop? I can put them back in the trailer? Let me know.

I removed the adapter heater band from MP22 to put on 23 so it could start up. It's wired into the same terminals as the nozzle (R1 and S1)

MP20 broke all the ejector plates bolts and had to be replaced. Also the plate guide bar was badly bend. Darryl and I straightened it in the shop press enough to be useable.

MP21 stopped working while in production. Nothing would move but the sled. Also the clamp and screw position wouldn't read. We powered it down about 3 times and it allowed us to move the clamp so we could reset the mold thickness. Everything started working then. I've seen it do this once before a while back with the same problem and solution.

Mp#5- fhd current input #1 exceeds limits alarm.
Changed the fhd current index for extruder max out value to 12000 from 16000. Per Josh's advice. No further issues this shift.

Mp#16- Used the heater band from #1 to get the heaters going on it. Noticed the sprue-break limit switch adjustment ring was slid back a little more than all the way up. This may have contributed to some bleeding off that occurred. Put a note on the press for operators to remind the techs each hour to check for bleed off.

Found a 400 ton FN7000 1999 model online last night. It had a 575volt.

 Still working on stripping MP-1.  We drained the hydraulic suction lines, & water from the heat exchanger. Mark removed the conduit & recepticles.

    I  removed the rear frame to access the pump & motor.

 

All the waste oil drums were full , so I moved them to the oil storage building for pick up. Walter said it would probably be Thursday before they could pick

     It up.  If we need an empty drum before then, there are two in oil storage.

Mp#5- had lots of metal in the nozzle. Typical baseplates? Grind it till we find it?

Mp#2- Nozzle has been running away somewhat. I noticed first zone was 5o degrees hotter than the nozzle the way setpoints were set. I checked the mercury relay and noticed it was not plumb, straightened it back up and tightened the screw on it. Compared pg 96 values with those of #5 press and set the PID for then nozzle the same. Also increased the scan time from 5 secs to 2 secs. (#5 was set at 1 sec). Next move is to change out from mercury to solid state relay, but I think much of the heat is coming from the process.

Started pulling more stuff from #1. Also made progress on the Yushin 900. I need to change out some sensors and replace missing parts and it should be O.K. to go.

Call if there are any questions.

#16 heater bands

MP 16 had a bad blow-back which cover all the bands but three and destroyed all the insulation from the barrel shroud. I was able to reuse most of the bands but we are missing or out of stock one of the nozzle bands. It's a 240V (2.5" X 1.5"). I left the old one laying on the press. The nozzle thermocouple is wired in and the tip band is on the press also.

#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-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

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.
