I have a couple of my yellow safety cords acting up on the Diamondback. They will be connected but yet the press shows "Yellow Cord" alert on the screen. This happens sporadically, including in the middle of runs. Does anyone else have this issue? Any fixes that you may know of?

Almost 8 years with our press never had that, hope we don't either, that must suck!! Is there anything that could be muffing up the connection? Maybe where they are connected at the machine interface?

There is a screw in the middle of the magnet. Make sure they are all snug. If you still have an issue contact me directly and I will help you out.
-
yep..its the screw in the middle.
Just backing Rich up on this…LOL
-
Yes I tightened them up and so far so good. Thanks!

easy to change, and easy to bypass if you don't have any. probably not recommended though.

Just a few bucks to keep an extra one on hand.

local friend calls me up..
"bro.. sigh.. my yellow cord connector broke.. what do I do.. this job has to go! "
This is the old style phono plug, not the new magnetic ones.
I can hear his son strumming the bass in the background.. "go grab his amp cord"
"Crackle of distortion as he yanks the cord outa the amp"
ahhh dad..
"thanks bro, works fine, talk to ya later!.. click!

gotta say i did something similar. the yellow railings that are put in front of the loading/unloading stations... ours are gone. i banged my knee on those things when loading so many times the first few weeks, in the middle of a run i went and got the screw gun and they were down.

Wouldn't want zero safety's on a C3, that tank will for sure chop you in half huh, wooooo. I got donked in the head with our air driven DB one time and that sucked. I couldn't imagine a ball screw or direct drive indexer smakin ya ;D
-
My CIIID has two safety systems. Yellow cords and a laser curtain. Won't gripe about either.
-
I like the idea of the laser curtain... is that just in the load/unload area?
on the javelin, it was a single 'safety cord' that went all the way around the machine... imho... more pita than it was worth.
I'd be likely to use the yellow cords, but those really don't seem like they'd truly stop you from doing something stupid.

Does it come with a Cone of Silence too?
-
Tony, if I told you that, I'd have to kill you. (did you butt dial me last night?)
Yes, it's for the load and unload stations.
-
Ha! You never know with me after hours. Heres our "Cone of Do Not Run Out of Ink"

Get ready to lose everything you own if anyone gets hurt by your press for any reason.. may want to put those safety items back in place..... JMO

Jvanick, is this you? ;-)
A quickly job on our new workhorse javelin (http://youtu.be/AmU11tfezpQ?t=1m34s)
-
Had cables on an older press but I really like the safety bars on the press I have now.

-
I agree. They are there for a reason. These machines can literally kill you if you aren't careful.
-
Jvanick, is this you? ;-)
not me. I would never stand between the platens on an operating press... what was he thinking?
anybody have a inexpensive source for the magnetic safety cables? If they're inexpensive enough, I might do some upgrading. The 1/4" phone plug setup on the old javelin sucked and didn't really add much in the way of safety.
he does load like me tho.. LOL.

I knew it wasn't you... just wanted to highlight that smooth move.
In his defense (not really), he is pedal indexing. Still not a good idea.
-
What was he even messing with on top of the press? Wired stuff.
-
Yeah, no clue... whatever it was, not worth it!
-
I really like the bars that we have on both our presses. Easy to open and close with a elbow or whatnot if your hands are full. I did remove the front one from our new machine that was in from if the loader and unloader. Post came up from the floor with bars on either side. Kept straining my back when loading because I had to stand farther back and lean over it. It's in the basement and every time I see it, I think to myself it would be a sweet good ornament! ;D
-
no wonder he has to take pills for back pain.
the older style cables on the gauntlets were a pain...we bypassed ours. it was an air press and if you got hit, it hurt, not testing that with the servo...i can only imagine.

Wait, there's supposed to be safety cords on a Javelin? My press must be reaaaaally old. :o

Our servo machine(S.Roque) has a sensor on the indexer, so if it hits something it stops. You'll get a bruise but no broken bones!

People were always bypassing the safety bar on Precision Ovals. Unfortunately an operator at Winterland got his skull crushed and died instantly. Tragic. You don't mess with hydraulics.
-
Why don't you guys just move the bars at the unloading/loading stations back in a little? We take full advantage of the safety features, no one has died yet.
-
honestly, even with safety features, you can still get into nearly any press and end up injured.
-
We had the same issue but it had nothing to do with them not being tightened.
Over the last 3-4 weeks the error would come up randomly sometimes very often but it seemed tied to an indexer issue which when we adjusted that a bit the stop errors just about went away for a couple days and came back lightly. Finally 'pin' pointed a slightly weak spot in the yellow cords if you can even call it that because it always reset fine and had no yellow cord issue until actually indexing and printing between head 6 and 7. We replaced those cords and since then haven't had the issue to my knowledge but it's a pain trying to deal with those cords often.
I feel like the bars are always easier to manage and less headaches, one hand operation...easy to trouble shoot. We also had to replace a slightly damaged yellow cord on our CH3.
-
I know this is way off from screen printing, but back in my days as a cut man doing construction we would tie the guard up on the saw blade, which meant the blade was always visible. I don't know how many of you have every handled a skillsaw, but that was pretty dangerous, but if you was a cut man the faster you can cut and stay ahead of the nail crew you'd do it...just remember never to lay the saw down blade first, and watch for osha ;D. I think we all bypass safety rules in every industry or job we do in some way, but it is there for a reason.

And we know the tales of the M&R Death Machines from days gone by. Don't make me dig up that mannequin.

. There are advantages with both bars and cables. We will stay with cables as when the circuit is opened you truly know its open where the switch on a bar can go bad in the closed position and even though the bar is open the circuit can still be made. Just a FYI on our reasoning.

While your statement might be true about bars, I can lean into the cables without them coming apart somewhat and still get hit, where with the bars I can't. Since you guys are the leader's in automatic press's what do you think about using a laser light for safety bars or do you think they would be to sensitive. I know the one we have for our front doors will catch everything coming in, even if a strong wind blows the door in a little it goes off.

We use lasers on a lot of our presses and have an optional system that can be put on all series II presses and up. When done properly you can no longer "card ink" while press is running and if you walk up to the heads and are within arms length the press will stop. There is a scanning laser at the load/unload station that is active when motion is detected on the pallets which means no pre-start to loading a pallet as it is coming into the station or reaching to get a lint ball/straighten out a wrinkle as the pallet is leaving. Had it for years! Really safe and 20% less production at least. That is why the word optional!

Yeah, that statement was kind of funny... TMI... I don't need to know about your pill popping problems.

I used to train the new press ops with a cantaloupe or watermellon..
I'd put it next to the frame holder and index.. their expression usually matched the mess on the floor.
Lets not forget the press I learned on.. american auto.. chain drive 6 color.
That shop had the press because where it came from, a girl was bent in half and broke her back.
-
one of the main guys @ New Buffalo, Merle - 244 may know him, he was telling me a story of a girl that worked there long ago, went under the safety cable to adjust something, the machine indexed -we're talking a giant Formula - she got hit and it pulled her under the flash, she was stuck in the press, under the flash for a few minutes, they had to unbolt the flash to get her out..... burnt her pretty good....can't mess around with these kind of things, one slip up and next thing you know, you're missing a finger, or a forehead.
-
On the first prototype allover M&Rs they used weight sensitive floor mats; as it took 2 people to load. We had a lightweight guy on the screen side shift his weight and tricked the safety to think no one was there and the servo indexed him under the screen. Damn near almost printed the poor guy.

In 2005 I had the top of 3 of my fingers of my left hand cut off on a table saw.. I was doing exactly what dude was doing in the vid- taking half an inch off of a 1x4, the guide came loose and instead of turning the saw off to tighten the guide rail I just reached in with my right hand to tighten it, the wood bucked an threw my left hand into the saw blade.
My first thought was I'm too young and handsome to be an amputee what will the ladies think. Vanity top priority.. Luckily Howard DC had a hand specialist and she sewed them back on, 6 months of therapy but still no feeling in them. They look good though.

I used to work with a guy who lost his thumb in a similar way but was unable to recover the flesh.
the doc asked him what's more important to you, holding a beer or wearing flip flops..
His thumb is now his big toe.

Whatever, you guys are nuts for removing the safety features. Even if you an still manage to mangle yourself, those things serve as a reminder not to do it.

After a couple people getting arms and them self stuck in the press we improved our safety on our Sportsmans. It will still hurt but at least kill the indexer.

I like lasers and I like the bars. The easier you make it to get into where the operator needs to get without cheating the safety circuit, the more likely the safety system will be used properly.

I think you guys need to increase the standards in the hiring process if that's been a problem :)

I agree with Rich the bars are nice but really easy to have a fault. On our press we already had to bar switches have the little tiny allen set screw come loose and render the bar useless. So now we make it a point to occasionally check the set screws for tightness and add a little lock tite to them.
-
presses with bars should probably have a 'you need to exercise the bars' function in the startup routines for a once a week test...
if you don't have a way to test things, you'll never know if they're working correctly or not...

my stepdad was a machinist (ww2 vet, navy yard machinist 30 years after that) and told me that if i had a set screw that was coming loose, put a flat set screw on top of it. once its tightened the set screw shouldnt come loose. avoids the use of a locktite that can settle into the allen socket which might prevent use of an allen wrench.
do not use a conical set screw on top - it will damage the allen socket for the wrench.
this was the way he did it years ago, im not a machinist - maybe things have changed?
-
Set screw trick is still common practice. Easy solution for inkman is put a little dab of clear silicon on the threads then run the screw in. Creates enough bond to stop the screw from baking out with out the risk of locking it in forever with Loctite.
