3/2/10

Worked on core # 2 pull sensors on mold # 74046-01 in MP4. Two of the three hall effect sensors will not read up the magnets in the hydraulic cylinders. The top sensor works as long as you don't tighten down the hose clamp too much. I found two more sensors in the shop and tried them. They work with a strong hand-held magnet but not on the cylinders.

Robot #10 stopped 3 times within a 5 minute period and never messed up again. Two of the stops were in the mold accompanied with a "Mold not open. Robot in unsafe position" alarm.

Cleaned the two new presses and started painting them. I will try to finish tonight.

" C " SHIFT

MP- 25  Changed  nozzle T.C. to “ J “ type so it would run in auto on DME.

 

MP- 23  Nozzle adapter heater band went out ;  replaced.

 

MP- 17  Chiseled Santoprene out of grinder. It had two different colors in it. I guess it had been running all night.

 

MP- 10 Robot only stopped one time. They wanted to let it run . I guess we’ll try & fix it on the next run.

4.1.10 D shift

Clear out the area for press#1 and capped off the heat exchanger lines.

Changed out a color mixer motor on #9.

Robot on MP#10- has been stopping every hour or so. It has been stopping over the conveyor after it has dropped the parts and goes up. It readily homes back and restarts. I mentioned stopping it to work on it but Marty did not want to leave it down for any length of time.

Call if there are any questions.

MP22 Star Robot Operational Update

We had a service tech from Star Automation in here yesterday on a courtesy call to help us out on some issues we have been seeing with the TW1200 robot on MP22.  Listed below are some corrections that were made that I wanted everyone to be aware of.

 

1)     Insert Arm L5 Home Limit Switch-

We were having an irritating problem with the robot not wanting to reference or return to the home position without the L5 Limit Switch being made.  Since we’re not currently using the Insert Arm, we corrected this by moving the L5 Limit Switch closer to the traverse beam and set the “Avoid Position” for the Insert Arm to 0.  Now the Insert Arm should never move off of the L5 Limit Switch and cause this problem.  Also because we moved the Insert Arm closer to the Traverse Beam, we were able to move the Product Arm Limit Switch closer to the Traverse Beam to give us more Crosswise stroke on the Product Arm.  Now we should not have to open the mold as far to remove parts.

2)     Part Grip Circuit-

The Part Grip circuit was not functioning because the robot’s previous owner had wired the valve output down to a plug at the EOAT.  The valve was rewired and now functions correctly.

 

Also, if you’re like me, then you have been having problems getting this thing to reference when you first power it up.  I would get an alarm saying “To make sure there is no interference with the Traverse Beam and to perform Posture/Rotate in Free Operation Mode”, or something like that.  What I learned yesterday about referencing the robot and homing the robot both is that it works a whole lot better to exit all the way out to the initial screen first before homing/referencing the robot.  There are two ways to home the robot-  First you can hold the “Dead Man” button until the bar at the top of the screen turns yellow and then hold the home button, or secondly you can turn the switch on the pedestal to “Origin” and then press the green “Start” button on the pedestal.  The light on the “Start” button will blink until homing operation is complete.

 

Call or email with any other questions.

Thanks

3.28.10 D shift weekend

Worked on Pm's most of the weekend.

Put the remote and blowback option on the 1 shot loader. Checked it, it works fine.

Looked at the Jet Loaders and Jet select valves. We really need the jet selects when using them for multi loading application. Talked with Mark about it and there may be a cheaper alternative to buying jet selectors? Might be able to use conair or off brand pocket valves to do the same things? Just a thought.

I need to obtain a Yushin pendant that works. I remember there were about 4 good ones from when I initially checked them all out, but now i cannot locate them. I am going to try to get the one on 16 going first.

Started putting SPI on #16. haven't tied it in, but have the box and wiring numbered and run already.

Had mostly minor issues since we were not running very much this weekend.(SLOW).

I will be out this Thursday, call if there are any questions. I will call back on Tuesday.
