Worked some on the Eagle sole plate press controls, the main panel is wired and installed.  Gary mounted the cabinet and is working on some sensor mounts.  Ordered the solenoid valve block for this station.

 

MP20, process tech had problem with new DME cables not fitting or clamping up right.  They were six pin instead of five pin.  We have both on the floor, but we only stock the six pin.

 

MP13 shut down, ends up the front door switch was not made.  Use code 100 to find out.

 

Helped Elaine establish a healthy list of Robot EOA components and Josh ordered today from EMI.

 

Talked to EMI guys today about a quote for (3) Decline Conveyors for new machines.

 

Ordered two new hydraulic cylinders for one of the new molds.  Ortman brand.  Should be here in 4 days.  They are prepped for Go switches.

 

Ordered more Omron micro switches for new molds.

 

Ordered (2) station junction boxes from Motion.  Daman brand.  Hydraulic, 3/8” Ports, 3000psi working pressure.  Should be here 1/15/10.

 

Worked on MP14 sub station.  Replaced LH pneumatic PB on cord hook snap.

 

Loaded the truck headed for Zag with the Wittman Robot and Air Skates.

Took apart and tapped three hydraulic cylinders on the new molds for 3/8" pipe thread. Only had time to put fittings on one cylinder.

Made a bracket for MP22 conveyer to keep hoses off it.

Worked on dual ratio valve on MP23. It wasn't loading regrind.

Wired a new heater and thermocouple on a mold that came in the shop.

Thermolater T31 tripped the motor overloads. The motor is bad and will not start. I got a new one from MRO and a pump seal kit but didn't have time to replace them. I'll try to get to it tonight.

Very uneventful tonight. Worked on PM's throughout the night.

Replaced ejector hose and fittings on MP#17, that were leaking. Went over fittings checking for tightness and redid o-rings as needed. Made a hose for it. ..
Question:
Do we need to put some kind of form at the hose crimper to keep track of what gets used? Who keeps things topped off there?

I did get to look at the support site and viewed some of the new equipment coming in. Looks like it is in great shape.

Let me know how I can help with the upcoming install/replacement of
machines and robots.

I will be working this weekend, be back Friday evening. Call if there are any questions.

#23- worked on the regrind / virgin loader blender controller. It was not functioning. Found a bad valve, when I looked at the other controller, it had a different valve, so I changed out the whole controller, and it worked fine.

#5- The robot conveyor belt tripped out, after looking at it, the NO contact was bad. I put a jumper across it since the tether had already been removed anyway. Working fine now.

Mark and I looked at the robot on #8, for future reference and to eliminate process tech changes, the Timers set-up is as follows:


Delay Before Sprue Grip: 2.50 sec (Grabbers)
Delay Before Part Grip : 2.00 sec (Kickers)
Delay After Sprue/Part Grip : 0.50

Continued working on PM's, I mentioned to Bill that he might see if Jerome would schedule the fans to run in 22 or 23 so we can have a repair window for the leaks on #21. Haven't heard anything back yet.

Also: I looked at the new mold with cores,, unless we change the cylinders we are going to need to install some mechanical switches to read set/pull with it. Maybe attach locking collars or position flags with microswitches??
They are not done tearing it down for cleaning but likely they will want to sample it soon and we will need to decide how to proceed.

Call if there are any questions...Sean

#15-Nozzle was leaking around threads. Tried to tighten it but it still leaked so I changed  it with one I'd faced off.

#8-Robot missing parts. I started the machine back up and fixed the robot and ran it for an hour to verify it was ok.

#9-Robot missing parts. Two of the suction cup level compensators were worn out and allowing the cups to moved around freely. Replaced them with new ones.

#15-Water leak on feedthroat fitting. The  cooling hose had been cut down to short and was catching on the sled so I added some to it and replaced the fitting.

Thursday, Jan 7, 2010

 

Started the day with problems at MP10, the connector nut insertion station.  The left side was jamming every 10 parts or so, with somehow feeding (2) black nuts and trying to press them.  It ends up that it was an inertia problem with the black nut slide, it traveled so fast outward and was bumping the track so that the first nut moved forward and allowed a second nut to feed down in place to be pressed.  We disassembled the left side, installed a directional flow control on the black nut slide cylinder and adjusted it about half way and reassembled.  The problem went away. 

 

There was an eight bank D-M-E heater controller and some cards that were burned up, probably from inserting or removing cards with the power on.  Ronnie and I gathered enough new components from MRO to put a new system together.  The problem was that who ever ordered the new D-M-E controllers a few years ago, ordered them wired 240V three phase.  So we had to rewire the controller for single phase 240VAC.  After checking everything out plugged in to a mold, I attached a label indicating not to move cards with power on. 

 

Helped set up robot on press 25 for brush roll end caps.

 

Snowing today, I heard the plant was closing at 4pm because of weather.

1/7/10  FYI

 

Stiffener and nut press station at MP10 would not seat the stiffeners consistently in the plastic connector.  Ronnie and myself checked the machine, it was OK.  Ronnie increased the supply air pressure to max line pressure.  Still problems.  We checked the parts and it looked like the opening in the parts for the stiffener was smaller than the print allowed.  On further examination of the inside of the pocket where the metal stiffener seats, we found additional plastic down in the hole about three-quarters of the way down that provided interference.  We checked the chiller temp, set at 53 degrees.

Checked the water and water flow.  Cores for the stiffener pocket were blazing hot.  We got the process tech to slow the machine down from 54 seconds to 59 and immediately the parts looked much better and we were pressing with no problems.  I believe the correct cycle time on paper is 60 seconds.

Mp#7-had to replace fuses in the 120/240 transformer. The DME box arced when they were changing out cards.
Marty asked me to put an EOAT together for the wheel cover they were running, its running good.

MP#11- replaced 2 hydraulic hoses to the ejectors, they were worn and looked like they were leaking in several places. Checked operation, good to go.

Worked on PM's on machines and robots most of the night with other odds and ends such as making mold lock straps etc.

If there actually is bad snow, I may not be able to come in, I will try anyway if the roads are clear though.

Cleaned up in preparation for the "QVC film crew" which is supposedly coming in this week.

I tried to get as much tagged equipment repaired as possible. The only thing left was that dryer DR20 which for some reason iss not providing a control output for the regen beds to kick in? We may have some spare parts somewhere or I can try to swap out parts with another dryer when possible.

Had a few minor issues this weekend, I turned in workorders for most of them. Have a good day call if there are any questions.

   MP-11   I shut the press down & cleaned up oil on the clamp end. Found two leaks on eject. Manifold ,  tightened , & restarted press.

 

  MP-16   Mold not closing – error 122 – not making eject. back switch .   The eject. back jumper had a broken wire.

 

  MP-17   Hose on eject. manifold sprung a leak. Made up a hose & replaced. I made a hose for the other side too, but I couldn”t  find

              any ½”  boss fittings.

 

  MP 6,7,8,10,11,& 12    Vacuumed oil pans Then emptied oil vac.  I started on # 1 ;  The vac .  will probably need to be emptied again.

   MP-7     Loader not pulling material --- Hopper feed at mezzanine not opened all the way.

 

   Vibratory welder -  Had filter clog alarm ;   Installed new filter .  cleaned up all the parts & oil under welder & on top of tank.

                            I let the oil heat up & cycled it several times ;  found one leak at press. gauge fitting & another at tank lid mounting bolt.

                             After it runs awhile , I’ll check it again.

 

  MP- 25    I emptied the oil jug @ injection end of press;  this was the second time in two weeks it has over flowed . It looks like it is coming from

                 the  injection cylinder . Will need to order parts & schedule down time for repair.

Replaced belts on grinder #19.Put a new gripper on #22

12.29.09 night shift

Changed several heater bands on #3 at Bill Potters request. Also repaired some of the wires and re-did the paint on the barrel shroud. Checked it and it came up to temp fine.
While it was down went over some of the leaks and cleaned it up in general.

#16- had a problem with ejector back limit switch...it needed adjusting, it was making the clamp sound really awful when it closed up, and also would not lockover and build tonnage.

#4- made a new core cylinder hydraulic hose.

#5- replaced a core line quick connect and tightened all the lines up. It looked like the two fittings on that block really needed those o-ring/washer sealed types of fittings but I didn't find any to replace them with.

#11- has several leaks but is #1 priority on the schedule, so I attached work orders to the machine...1 for the tool and one to let the techs know to notify us when it is down so we can fix those lines above the clamp cylinder (ejector line fittings).

Call me if there are any questions!

MP#5- Mark and I put the pump in and I started it up. I ran around 40 shots of baseplates through it and shut it down. It is working fine. I then put the tool arm back on the robot and referenced it. Had to locate the loose plug connection in the controller first though because it would not power on at the pendant. It should be ready to start up this morning if they want to run it.

#11- has stopped a few times (4 or 5) throughout the night from 3217 alarm...which I think is the core switch signal...but when checking it out further, the signal IS made... so?? It starts right back so we have been keeping it going.

#2- The sled cylinder coupling was ran out too far and loose...I adjusted it and tightened. It was causing the frame to twist very badly when the sled was ran back all the way.

#25- Initially Mitch had made me aware that Zone #2 was over heating by 30 or 40 degrees. We found later that the feedthroat was partially blocked from old Nylon and liquid color residue. It kept slipping while building up a shot and taking much longer. While it was not running the barrel temps maintained and stabilized. After we cleaned it out it was fine. I also helped them process out the splay problem...they were short handed.

I came in early at 3pm so I am leaving at 4 am. Mark said he must leave early today so I may also come in early today.

I put the straps for Bill Potter in a box with his name on it in the Molding Office so he would find them.

Call if there are any questions.

12.23.09 Nights ...Sean

Mostly cleaned up in the shop and helped the process tech do a mold change etc.

Worked on the dryer in the shop, found a loose wire connection on a relay block terminal.

There is an oil line leaking on #11 (ejectors) but it was running and they did not want to stop production.

I talked to Mark last night and he is going to call me when the pump for #5 comes in on Monday so I can come in early and we can both work on it.

I wish all of our team a very Happy Holiday!

Worked on Star Robot on MP24.  Display was dead on power up.  Disconnected all I/O connectors on the main power board with the power off, powered up controller, and the pendant came back to life with errors.  Started plugging in connectors one at a time with the power on and CNA made the pendant lose power.  Looking at the prints, connector CNA has limit switches that are around the EOAT, on inspection of this area I found that a cable labeled LS4 that had bare wires that had got together.  I insulated the wires from each other and everything powered up no problem.  I was able to move the robot around and send it home.  So evidently a short with the 24VDC will not allow the system to power up.

 

Changed over the Z axis encoder on MP5 to a BEI encoder.  On power up the robot could not find itself, so I swapped the A+ and A- with the B+ and B- channels.  On power up this time, the robot referenced fine and homed itself.  There is a box on my desk with (1) new BEI encoder, connectors, pins and sockets, and a print.  Since we are out of the old encoder again, we should start changing over to the new encoder on a failure.  We only have (1) new encoder right now but more are on the way.

 

I replaced, dated the PCB backup battery in MP25.  It has an NC9000G controller and only has (1) back up battery.  They are supposed to be good for 5yrs.

 

I replaced, dated the PCB backup batteries in MP22.  It has (2) batteries like MP24, (1) on the back panel and (1) under a cover on the back side of the main cabinet door.

 

Called Milacron to track the pump for MP5.  They said it didn’t go out till today and wouldn’t be here until Monday, the 28^th.  I feel goobed.

 

I believe I heard that new GO switches are here and are in MRO, I think several have been robbed.

 

That is all I have for today, have a very Merry Christmas and we will see you next week.

I took the inverter out of #22 robot the other night because it kept tripping the breaker. It had a bad 3-phase full bridge rectifier and I found one online for $34. Mark ordered it and I put it in and tested it out and everything seems fine. They haven't ran the press so I'm not sure what program is in it.

The insert press on MP10 quit working. I found a loose bolt that the sensor has to see in order to start.

The z-axis encoder went out on MP4 robot and I think we are out of them. I switched it with the MP5 since it's waiting on a pump.

The robot on MP24 will not power up the pendant. I tried the pendant from 25 but no luck. The control board does have power but the board's lights will not come on. I planned to switch boards with another similar robot but none were down.
