MP-24  Installed a relay to give a gripper signal when the arm is in the up position. MP-22 & 25 already have a relay.

 

I worked with Tony Cannon & Doug Mason setting up the Branson welder for the vacuum inlet assembly.

 

We got in eight different sizes of rubber plugs to use on hydraulic lines & valves. I put them under the hose crimp bench.

 

MP-10 is to stay down all weekend. The nut press fixture has to be changed to work with the engineering change made to the part. Mark & Gary will

          finish it on Monday.

MP#21- I adjusted on it for a long time last night and finally got it to where it responds and is shooting good parts. It is still not responding like it should be though. The extruder is working at a functional level but could be better, it is a little slower than it ought to be. Josh mentioned that we may try to get a calibration procedure for it on Thursday.
I ran it on the robot for 2 hours and then shut it down because Marty did not have an operator for it. I posted a note on the door to let techs know that it has had the pump rebuilt and system pressures may be different than before.

Robot on #25 needs a new runner gripper sensor. We could not use it because it is reading "on" all the time and alarming LS4S alarm the robot when you put it into auto. I checked it out and found the wires had pulled back into the conduit and may have shorted. I tried to leave them disconnected but the alarm still would not clear. So I borrowed the sensor from #24 and it did not work either. May have a problem with the board. I left it disconnected until we get a new sensor. The wiring will need to be double checked before installing the sensor.
The robot works, just not the sprue grip arm because of the sensor alarm LS4S.

Have a great day,

Sean

MP#2-Mounted R2 topcover belt door fixture onto the other fixtures table so they could use it. Evidently we took the table to use on another project. I drilled the table so either fixture can be swapped out with the same table. When they are not using it, we can make something more permanent.

Mp#21- Hooked up the ASL filtration cart and let it run on it for a month. Try to watch that the pressure gage does not go over 35. If it does, we will need to backflush it. Procedure for that is on the cart. We can move it around every month to each of the presses we think may need it.

Continued with PM's.

Have a great day.

MP-21  Got info from Toshiba tech. to check pump pressure – Press is ready to run.

 

MP-4  Replaced two hydraulic hoses & adjusted the angle of the fittings to keep the hoses off the deck.

 

Wiring cores & eject. switches on new molds.

MP-12  They had some more trouble with the injection encoder rail gear. I found a new gear in the L-1 cabinet. Mark installed it. I put some grease on the extruder

            follower  arm – it was squealin !  I’ll order some more of the rail gears.

 

MP-24  I hooked up an eject. back safety switch.

 

MP-21  I drained the oil tank & pulled the tank inlet strainers. They were both 90% clogged. I cleaned them in the parts washer & reinstalled. Josh wants to run

            the static filter on it for awhile; because there’s still some sediment in the bottom. I cleaned out what I could reach with the oil vac.

 

MP-25  Cinn. Milacron dryer kept going into high temp. alarm. First I thought it was the mercury contactor sticking. It turned out to be a loose connection – the

            process temp. probe at the board.

3.21.11 D-shift Sean

Mp#21- Filled it all the way up with oil. Ronnie and I found the Suction line gage missing and reinstalled it on the pump. It would not load up with any pressure. I noticed the suction gage was not indicating any suction so I removed the gage and tried to prime oil into the pump, then replaced the gage and tried it again. Still not building any pressure. The nozzle will move and the ejectors did briefly but then quit. I tried to probe several valves (M1,M7, 102,104,gatevalve, etc.) in an effort to possibly "unstick" anything but no luck. Left it down to let air settle out of it and because I am afraid it may be damaged from running with the gage missing.





Mp#22- IML was running and the "low Label" light was staying on. He thought it was a sensor but it just turned out to be low of labels.





Mp#8- The operator they call "The Crow" fell asleep on the fans and crashed the robot. I have a picture for you.





















Continued with PM's.

Have a good day.

MP-21  Mark & I installed the pump. I started it up & it ran quiet, but after a short time, it started heating up & it is still pumping air into the tank. I believe the

           tank inlet screen is stopped up & the only way to get to it is to drain the tank. I locked it out again & we can get back on it Monday.

 

I helped Henry get the new molds off the truck. The three smaller molds had fallen off the pallet – no damage – just a pain to get to.

Mp12 the strip gear on injection position sensor broke not sure how. Its just glued on so I cleaned reglued so if you have issues with screw position check this first.

MP- 1   Installed a cover on the touch screen control.

 

MP- 10   The nut press wasn’t working. The nuts weren’t sliding down the left side track; cleaned it – working now.

 

MP- 24   Replaced a broken roller on the operator side gate.

 

I didn’t see the pump for 21 yet. If it comes in tomorrow we’ll have plenty of time to install it since molding is down for two days.

Update 03-16-11

Hey Guys,

I just ordered a new Star Sprue Picker for MP26.  I also ordered a new 5/16” screen for the green small grinder on MP22 (GR21).  It has 3/16” screen and is grinding Santoprene and getting clogged up frequently.

I finally convinced Ken that we need to order 2 of the Special AEC grinders that I had spec’ed out to especially grind warm rubbery materials.  He is turning in a CER for it today.

The pump for MP21 is due back in by the end of day today.  Mark is out today and I have to leave at noon, so I told Ronnie just to prep it for tomorrow.

 

Thanks and keep up the hard work.

MP-6  Adjusted the gate cutters; one side wasn’t cutting close enough.

 

MP-7  The portable hopper loader motor burned out. Replaced.

 

GR-4  I flipped the stationary blades & removed the rotating blades; no more blades in MRO. Also one of the adjustment set screws is missing from the front

           stationary blade ; it’s metric.

 

I vacuumed out the oil pans on MP-6 -7 & 8

Mp#25- Has been stopping for core bwd limit sensor. I found the core cylinder was loose. It has stopped a few more times infrequently. I have checked the wires on the switches and plugs. At this point I think the mold cores may be getting caught up and not pulling after it shoots parts.
It occurs about once every half hour, and always at the same place in the cycle, right before it starts to open and cores are pulling. I added some time before opening to it and it seemed to help.

Mp#14- The machine would shoot parts and then stop before building a shot again. Then the clamp would not open up in manual. Checked many switches, etc. Finally found the mold touch switch (LS2) was flickering. I re-adjusted it and checked operation, no further problems.

Continued with PM's..

MP-2  Cores not working – The hydraulics were hooked to core 1 & the switches were hooked to core 2. I moved the plug to # 1 side. It still wasn’t shifting.

         I found one of the male quick connects was bad.

 

I emptied all the Nissei over flow jugs & the oil vac.

 

I moved the grinder from MP-12 to the shop. I cleaned it out. We need to order new blades for it.

 

 MP-1       I changed out the grease tube on the lube system.

 

They brought 3 scales to the shop for repair. I  cleaned them up & adjusted the level.  2 of them work fine, the other one I’ll take to Craig to check out. It

       wouldn’t hold the zero or the tare setting.

Finished Packing up the pump and weighed it @139lbs.

We had a power failure at 11:02 pm last night. It tripped the #3 panel which fed the North Bus. I was able to reset it and the air compressor and we were going agin shortly after 12:00.

Mp#9- The Z-at part drop maximum limit needs changed in the HMI's. It would not hurt to set them all that way, or make the value accessible from the touch screen. Maybe add it to the speed control page.

Continued with PM.'s!

Call if there are any questions.

Mp#23- Potter asked me to look at the mold heater circuit. It checked out alright without taking the tool apart. It just appears they are not getting good heat transfer inside the mold. Heaters checked out and T/C's did too. They will need to pull it ouit and take it apart.

Mp#18- Had trouble with zone #1. Could not get the controller to output a signal. Found a relay with a bad set of contacts, moved wires over to a spare set on the same relay. Never could get the controller to send a signal. Changed it out 4 times and finally got one of the very older analog types to work correctly. I only had used stuff to try out, so we may need to order a new one to put on the shelf...when the money returns?

Mp#15- Did not get very far with it. I pulled the M1 valve of and cleaned it, it was very clean and solenoids ohmed out good. Reset mold thickness, etc. and bled out the air, problem remains.
Will proceed some more tonight.

MP-21  Worked with Josh & Mark trying to figure out why it’s generating so much air in the oil. Mark is checking into having the pump rebuilt. It’s down

            until we get a response on the pump.

 

MP-15  I replaced the C-7 check valve, still no go. The Toshiba tech. said we’re in the right area; sounds like something isn’t shifting fast enough. I did all

           the system pressure tests they told me to try, & it checks out OK, so at least we know it isn’t one of the pumps. The next step is to start pulling the

            clamp valve stack apart & check for sticking spools etc.
