Ax­e­lent way to guard ma­chin­ery

DEMM Engineering & Manufacturing - - PRODUCT WATCH - Con­tact 09 526 4344.

Ear­lier this year Con­cen­tric En­gi­neered So­lu­tions in­stalled Ax­e­lent X-Guard mod­u­lar safety dis­tance guard­ing around a num­ber of ma­chines at a cus­tomer’s site in East Ta­maki.

Ini­tially the cus­tomer asked the firm to de­sign some be­spoke guard­ing for their ma­chine. While un­der­tak­ing this work Con­cen­tric En­gi­neered So­lu­tions came across the Ax­e­lent prod­uct. Its staff dis­cussed this as an al­ter­na­tive with the cus­tomer, and ended up pric­ing both op­tions to com­pare.

The Ax­e­lent X-Guard prod­uct came in at ap­prox­i­mately 40 per­cent cheaper than the pur­pose de­signed guard­ing. In­stal­la­tion of the X-Guard safety guard­ing was go­ing to be con­sid­er­ably quicker than the be­spoke op­tion, which in turn of­fered fur­ther cost sav­ings.

Ax­e­lent X-Guard is man­u­fac­tured in Swe­den and com­plies with AS/NZS 4024-2006 and its Euro­pean coun­ter­part ISO 13857-2008. The guard­ing fea­tures in­clude a 50 x 30mm mesh aper­ture al­low­ing a safety dis­tance from a haz­ard of 200mm, and mesh panels that can only be re­moved with a spe­cial key – op­er­a­tors and staff can­not re­move panels with com­mon tools such as Allen keys or span­ners.

There is a range of hinged and slid­ing doors, yel­low pow­der coated posts and black pow­der-coated mesh and com­po­nents, and mesh panels are avail­able in 100mm in­cre­ments from 250mm to 1500mm wide. Stan­dard heights are 2,000mm and 2,300mm.

Con­cen­tric En­gi­neered So­lu­tions cre­ated a 3D model in Solid Edge of the ma­chine, then used soft­ware sup­plied by Ax­e­lent to cre­ate a pro­posed guard­ing so­lu­tion for the cus­tomer.

Once the cus­tomer agreed on the pro­posed so­lu­tion a 3D model of the guard­ing was gen­er­ated by the Ax­e­lent soft­ware that was re-in­serted into the Solid Edge model. The cus­tomer then used the 3D model of the ma­chine and guard­ing to get in­put and buyin from pro­duc­tion staff.

The cus­tomer used the mGard trapped key sys­tem from Fortress In­ter­locks to se­cure the dis­tance guard­ing doors and in­ter­lock them to the ma­chine con­trol sys­tem.

Con­cen­tric En­gi­neered So­lu­tions de­signed and man­u­fac­tured a range of lock and latch panels with han­dles for the va­ri­ety of door op­tions used on the ma­chine guard­ing to suit the mGard trapped key sys­tem.

The lock and latch panels were made out of stain­less steel to match the mGard com­po­nents and elim­i­nate the chance of the panels be­ing scratched over time when com­pared to pow­der coated steel.

In this sit­u­a­tion, dis­tance guard­ing was the most ap­pro­pri­ate so­lu­tion for the cus­tomer. Con­cen­tric En­gi­neered So­lu­tions can of­fer both the Ax­e­lent X-Guard mod­u­lar dis­tance guard­ing prod­uct or be­spoke guard­ing so­lu­tions for your ma­chin­ery.

The firm has a good work­ing knowl­edge of AS/NZS 4024-2006 and can of­fer the com­plete so­lu­tion in­clud­ing elec­tri­cal de­sign and con­trol sys­tem in­te­gra­tion.
