Title: Well, it happened...
Post by: Get Shirts on July 09, 2016, 04:00:40 PM
A while back I was printing some sleeves late at night, tired and it paying attention.  Leaned in to adjust the shirt I just loaded and BAM! The pallet caught my hip and pulled me right into the head.  Scared the crap out of me.  The press stopped, I thought it would out a hole in me.

Thank God for safety cables.  Glad you weren't seriously hurt.

That's the thing, we didn't trip any safety cables.. It just stopped.

I guess this is something I should know, but is there a sensor on M&R's that detects a certain amount of resistance and trips an emergency stop?

I can attest that at least on the Sportsman, you can grab the carousel arms and let the press pull you around...

I watched Francisco at the M&R Technician Training class show us how strong the indexer was... I wouldn't want to be in the middle of that.

I've had my Diamondback S stop after catching me in the hip before.

I got clipped in the hip by mine and scared the crap out of me, and it hurt.  I wasn't far enough into it where it stopped, it just pushed me aside.  Gave me a whole new respect for that machine.

This was a Sportsman E and it definitely stopped. Bruised the hell out of my hip and stomach.

Had the same issue with our Diamondback right after install (a week later). It didn't stop, a coworker pushed me out when he saw me getting dragged. Got lucky, would probably be in a wheelchair had he taken another second.

Safety first guys!

Unfortunately we have had a few injuries over the 15 years I've worked here.  Most were just bruises and hilarious stories.  One guy get pushed under the loading station but not before getting a whack to the head.  Dazed, he thought the guy trying to help him up was fighting him and he took some hilarious swings before falling down.

In my 7 years on press I never had even a close call.  I fear those machines.  Especially the C3.  That thing can index like a monster.

We used to have an all-air GT8...you could stop that with two fingers.  But the G2s and GZs and definitely the challenger are unstoppable.  I tried.  I got whipped over the loading station onto the table...no, I'm not always that smart.

In the past few years we have some excruciating injuries that I don't even feel comfortable describing.  We've updated our safety training and protocol extensively since then.

Same.  Did not feel good at all.  Lesson learned!

We also beat into the heads of anyone working on press to make sure the front frame holders are securely latched. On our presses where the screens drop versus the tables lifting, we found out (the hard way) that if it isn't latched and you are indexing with your set up pallet on, the block on the pallet MAY hit the frame holder. You really don't want to know what can happen. We were VERY fortunate that nobody was standing next to the head when it happened. It may not be like this on all the presses, but two of our four are like this, and we really to beat this into people's heads, from orientation to training and beyond.

I'm surprised it's not a requirement to have smart servos on ALL presses that once they sense any resistance the servo shuts off...... Our Roq presses do this and it actually saved my ass a few months back when I was being a dumbass trying to wipe lint balls on the screens while my guys were printing. My hoodie pocket got caught on a pallet which when the machine indexed it tried pulling me into the machine between print heads. Luckily I had my footing under me and the press caught the resistance and shut the servo down. Saved my little ass for sure! I saw a really bad situation in another shop several years ago that made me always made me want smart servos, glad we have them.

Alex posted a video last year of him taking a hit on purpose from his ROQ. It does sense the spike in current and kill the index motor.

Yes, anyone who comes into the back gets the speech that the rotating pallets are the nastiest thing in the shop and are not to step in front of them any more than you'd step in front of a moving truck, My press doesn't have and load-sensing stop function.

i wrote up a paper that describes all the safety procedures while working around presses.  it included pictures of the yellow cords, emergency stop buttons, indicator lights, not stepping into a press that can cycle (if yellow cords connected / emergency stop not pressed), dont walk behind press operator or unloader...  etc.  every employee has to read and sign that they have read and understand. 

disregard of safety procedures can lead to demotion or termination.  it might sound extreme, but i personally wouldn't want to work around someone that didnt care about my safety

 yes its an annoyance to follow procedures (ever have the end of a yellow safety cord fall in the ink as you remove a screen) but we havent had any accidents with our M&R or Anatol presses.

There's a shop near the one I worked at in Daytona that had their safety cables disconnected. I remarked that it was a lawsuit waiting to happen. I got "nudged" a couple of times on my first year on the Gauntlet, but I always kept the cables connected and eventually muscle memory eliminated a "nudge" after that.

That's such a great idea.. we have a pretty solid safety culture here, but do not have a press-specific set of safety procedures. Running MHM's so fortunately the safetys cannot be disabled easily. No accidents except for one artist who leaned a little too far in and caught her hip (like so many other stories I see here) but the written procedures and signed acknowledgement will be key to keep that going. Thank you.

One of our current press ops got a hard lesson in his first week or two on press. He was only assisting then. Shirt came around to the unload station, with a hefty dwell on the indexer. He thought the press had stopped and stepped up to look at the finished print. Indexed him right above the belt and knocked him on his ass. Literally took him off his feet.

We had thorough refresher safety meeting the next morning.

The servo indexers and the spot cleaning gun get extra attention at all safety meetings and new employee orientations.
