Core 1 wouldn't read the pull switch on MP5. Found a loose connection in the core plug.

When DR18 was started it would index then trip the main breaker to MP25. The process heaters were shorted. I replaced them and started it back up.

The robot on MP25 crashed in the core dummy plug. Straighten the robot arm and set it to rotate above the belt instead of the mold.

Friday MP05

I finally fixed the problem on MP05 where the screw would drift forward when the pump loaded for Clamp Open/Close and Injection Unit Forward/Retract. Fixing that problem also dramatically made Screw Recover better.

MP10-  Kept going down all day with the pumps kicking off.  Was getting a 5220 alarm, when indicates “Rear Door”.  On this machine, “Rear Door” does not refer to the Non-Operator side door, but the doors that are to the Rear (away from injection unit) of the machine.  I usually call these doors the “gates”.  Anyway, Mark noticed that the non-operator side rear door limit switch needed to travel a good bit before it was made so he adjusted it.

After this, the machine still kept going down.  We spent a little time troubleshooting it, but it finally got so bad it was doing it every shot they needed to run so I jumped wire #69 to #220.

This should get them running, but it needs to be removed later and the problem fixed.

It only does it when the mold is first closed, so it may be a short in a core wire or something.  The only other inputs grouped with the rear doors all seem to deal with options or the cores.  If something was shorted and dragging the voltage down on the entire group, this is the alarm you would likely see first because it kills the pump.

Mp#10 stopped a few times, the techs did not say anything about it until I asked. I caught it once but it was because it had ran out of material and did not make shot size.

Mp#8- looked into redoing the other EOAT in the shop. Could not locate any 5/16 -24 threaded rod to make standoff studs for the disks. Need to get some. I sent Mark an email.
I do have some ideas we could try with the classic fan EOAT.

Began greasing and Pm'ing presses. We need to update press assignments or work out a plan of some kind that works.

Mp#18- I have been looking into the interface details to tie in the sprue picker. I think that one of the interface boxes will work. I have started on some notes that I will submit for Josh's review on Monday.
After looking at the interface schematics, I think it might be likely we can make something similar from scratch to do a few more presses that only require pickers.

Call if there are any questions.

 MP-21   Replaced pump hydraulic Hose.

 

MP-26  Fabricated top safety door – It’ll work for now.

 

MP-24  Cores not working;  The eject. back common  on the machine side plug wasn’t hooked up. OK now.

 

MP-17  Cleaned up oil , replaced pads, & emptied jug.

Spent several hours on our favorite two presses today, MP8 and 10

 

It all started with MP10 stopping periodically. (The pump dropping out)  We wanted to rule out machine or robot.

A jumper was placed between pins 19 and 27 in the robot interface plug to bypass the robot estop stuff.

The pump would continue to drop out here and there.  It seems to always drop out when the robot is either on its way to drop a part off or down in the conveyor guard, so basically when the machine is clamping up or building tonnage.  Looked at the control cabinet door switches and added screws to keep control power on solid.  Replaced the bottom safety switch on the back door, fixed the latch on the back door, it was rolling back some after you closed it.  The purge cover door switch cable was just bare wires twisted together, wirenutted and taped it up.  This is where we got to when MP8

Reared its ugly head.

 

MP8 would not pick parts and the EOAT was all out of whack.  So a couple of hours later we started picking parts again on a consistent basis.

We should put our heads together with our tooling and look at some improvements.  Gary and I talked and he brought up some good points that could fix some problems we saw today.  Tie the two discs together at the proper center spacing, fab and mount them so they cannot turn.  Use a single plate across the tool to represent the discs and insert the two tabs into the plate.  Separate the gripper mounts from the disc mount so they could be moved independently.  Just some thoughts, we desperately need to do something.

 

We received our new hydraulic oil today.

 

Poppet valves came in today.

Mp#2- repaired a broken core sensor wire.

Mp#3-repaired the vacuum switch on the robot, somehow the wires got ripped out. I tied them up neatly.

Mp#4-There was purge material all around the nozzle heater wires. Carefully cut away material and taped the wires back up out of the way.

Mp#5- had borrowed the vac switch off that robot to get #3 running and then soldered back the broken one and replaced it on #5 robot. I checked and adjusted the sensor so that it was working good. It is O.K. to run now.

The edge fan that is running in the vibratory welder is in need of ejectors to eject it from sticking in the tool fixture. Even when the parts are cold they can be difficult to remove. They may already have an engineering change planned but if not, someone needs to take another look at it.

Cleaned up and 5-s'd in the shop. Have a good week, call if there are any questions.

  Mezzanine – Dryers 6, 21, & 32 – All  were in alarm; had to adjust index limit switches.

 

MP-22  Robot dropping parts;  Tightened up all suction cup mounts.

 

MP-16   Nozzle kept freezing off.  Replaced nozzle band.

 

Lubed all tie-bars. Wiped down & lubed tie bars on presses not running.

 

MP-21   Need to order new pump hose – back side- marked with red paint. It’s leaking at crimp.
