Morning all,
Any engineers or safety pro's out there with experience of using or assessing conical rounders or moulders?
Looking at some guarding options, but most seem to be guard free given the drum needs to be kept free of debris.
If anyone can provide any solutions with regards to safety devices I'd appreciate it.
Thanks

Not conical rounders but a lot of industrial machinery, and it seems that the company located opposite my lock up unit makes them! Trouble is I don't know anyone there, sorry.
I've just looked them up on the interweb thingy, and it seems that there is quite a lack of guarding around the moving parts on the one I watched.
However, the first thing that comes to mind would be "light guards" and a braking mechanism to stop the rotating cone.
The detail of this would depend on "if" the rotating cone could injure...

Hi, thanks for the reply.
You are quite right, there is no guarding on conical rounders/moulders. I really don't like them myself, however there seems to be a perception in the bakery sector that they are safe and require no fixed guarding, due to the rotating drum not presenting a risk of injury, and access being required to clear dough, scrape the drum ect. There is also very little guidance out there, and nothing other than generic PUWER hierarchy within specific bakery guidance.
Well...., I am now aware of an accident involving one of these, an operator got their hand drawn in and injured against the fixed guides which surround the drum, not serious, but in my opining could have been.
I agree with your control measures light or trip guards, and perhaps a magnetic braking mechanism being fitted, but just need to convince others of the same!

Could clothing get trapped between the drum and the guides and draw a person in? If it could then you are looking at a drawing in / entrapment hazard. From you comment it would seem so. Be careful with electrical braking as it requires energy to implement, so in the event of a power failure the braking fails also. You need a passive braking system really? Mind a lot of industry relies on active braking. You could also use STO on the drive, and torque limited slow speed control for cleaning. This is easy to implement, but, costs money and the bakery industry I suspect won't want to pay for it.
