The next gen­er­a­tion in high speed plan­ing

Australasian Timber - - HIGH SPEED PLANNING -

ACORA IS cur­rently in­stalling a Gil­bert 850 mpm planer and Acora Han­dling equip­ment at Tim­berLink’s Tarpeena mill which will join the suc­cess­ful in­stal­la­tion last year of a Gil­bert Planer and Acora han­dling equip­ment at Carter Holt Har­vey’s Ca­bool­ture plant, which has been run­ning ex­cep­tion­ally well for al­most year now giv­ing the plant record up­ti­mes and prod­uct qual­ity.

There has been a re­cent rev­o­lu­tion in the world of high speed plan­ing due to in­no­va­tive de­vel­op­ment and pre­ci­sion en­gi­neer­ing by Gil­bert Prod­ucts of North Amer­ica – these plan­ers are rapidly set­ting new stan­dards in planer per­for­mance and due to this unique de­sign and con­cept, are very ap­pli­ca­ble to plan­ning ra­di­ata pine at high speed.

The Gil­bert Planer is truly rev­o­lu­tion­ary in it’s de­sign – it was de­vel­oped by Gil­bert af­ter many years of work­ing on re­pairs to ex­ist­ing plan­ers in the field when they de­cided they could do a bet­ter job – Gil­bert spent five years on de­vel­op­ing their machine (1995 to 2000) and re­leased the first planer high speed planer in 2000 – since then they have sold more the 50 plan­ers world­wide.

The in­no­va­tion comes from a ground up de­sign, fab­ri­cated to pre­cise stan­dards in Gil­berts ul­tra mod­ern fa­cil­ity – a whole planer frame is en­tered into the CNC tun­nel and ma­chined to pre­cise tol­er­ances.

Per­haps the great­est in­no­va­tion is the Pull Through Tech­nol­ogy

• The planer runs with a gap so does not need a bridge.

• Be­cause of this, there is no end to end im­pact be­tween boards, and this is the big­gest causes of break-ups within a planer, par­tic­u­larly with Ra­di­ata Pine.

• CNC closed loop con­trol of all of the heads, means po­si­tion­ing is pre­cise and fast – to set the size, mea­sure the ac­tual size of the piece com­ing out of the planer, in­put this on the screen and the planer au­to­mat­i­cally cor­rects the head po­si­tion – only one piece needs to be mea­sured.

• Skip ad­just­ments can be made in the fly.

• The machine is ex­tremely ro­bust and pre­cise, a con­se­quence of this is they can run fast – up to 1200 mpm. But many ma­chines have been bought for their ac­cu­racy, re­li­a­bil­ity and ease of use, not for speed

• Up­time is ex­tremely high, Gil­bert guar­an­tee 95% up­time!

• The machine is flex­i­ble, it can be used as a planer and a moul­der – from com­plex pro­files to deck­ing to split­ting and changeover is very quick, there are Gil­bert own­ers that make 8-12 changes in a shift.

Gil­bert also sup­plies the in­feed and out­feed units;

Com­pact lay­out shown on draw­ing be­low. Only a one me­tre bridge be­tween the feed ta­ble and planer. Will fit in an ex­ist­ing and small lay­out. Al­lows for more space af­ter the planer to slow the wood down.

The feed ta­ble is a very sturdy and re­li­able unit with spe­cially de­signed pineap­ples, to give pos­i­tive feed­ing with­out tear­ing the wood and the slow down belts have au­to­matic po­si­tion­ing for each sec­tion that is run by the mill and the op­tional ad­di­tion of ‘chicken pluck­ers’ to hold the wood to the slow­down belt.

Pull Through Tech­nol­ogy

Gil­bert’s unique “Pull-Through” mod­u­lar de­sign is based on the fore­most Euro­pean tech­nol­ogy that has been proven to re­duce down­time sig­nif­i­cantly. Cou­pled with a range of op­tions in­clud­ing the Gil­bert In­feed Ta­ble, Pow­ered Bridge and the Gil­bert Au­to­matic Cut­ter­head Po­si­tion­ing Sys­tem the Gil­bert plan­ing sys­tem can be tai­lored specif­i­cally to any ap­pli­ca­tion and will sig­nif­i­cantly in­crease the qual­ity of tim­ber pro­duced.

The planer runs with a gap be­tween each piece of wood and wood can be ob­served trav­el­ing through the planer. Us­ing the pull through tech­nol­ogy each piece of wood is drawn through in­de­pen­dently of each other re­gard­less of the space be­tween each piece. Ben­e­fits of this sys­tem in­clude re­duced stops in pro­duc­tion and elim­i­na­tion of off­set de­fects. This be­comes par­tic­u­larly im­por­tant when you con­sider the jamb-ups that oc­cur in plan­ers due to brit­tle wood from over dry­ing and large knots, the con­ven­tional sys­tem of run­ning one board into the next, causes break­age of tim­ber in the planer. This re­sults in sig­nif­i­cantly less down­time (95% up­time is com­mon with Gil­bert Plan­ers.) Tim­ber can be seen pass­ing through the planer the op­er­a­tor is able to re­move bro­ken pieces at all times.

Fully Elec­tric Planer

To en­sure a steady speed and pre­ci­sion feed­ing, the Gil­bert Planer is pow­ered by an elec­tric mo­tor­iza­tion al­low­ing a high feed speed of up over 900m per minute. The feed rolls are pow­ered by heavy duty drive shafts uti­liza­tion self con­tained cas­ing to re­duce main­te­nance. This unique, en­vi­ron­men­tally aware sys­tem im­proves pro­duc­tion, elim­i­nates down­time and there is no need for hy­draulic oil.

With such di­verse ben­e­fits as low main­te­nance, elim­i­na­tion of off­set de­fects and un­equalled feed speeds the Gil­bert Pull Through Plan­ers are worth a closer look!
