Loading and stacking systems

Efficient CNC-joinery

Derix GmbH & Co.

Three iden­ti­cal VISION-III-TT 5‑axis sys­tems are in use at Derix, each equip­ped with a 16,500 x 3,600 mm steel beam table, con­sis­ting of 23 steel trus­ses with woo­den beam sup­port, and a con­vey­or sys­tem. Our desi­gners have enhan­ced the expe­ri­ence gai­ned from num­e­rous indus­tri­al solu­ti­ons and adapt­ed it to the requi­red per­for­mance for cross-lami­na­ted tim­ber (CLT) appli­ca­ti­ons. The result is a sys­tem that impres­ses in its every detail. This appli­es to the table con­cept in the same way as to the pres­su­re rol­ler sys­tem for fixing the pla­tes or to the extra­c­tion device with more than 14 blast gates, which ensu­re that the extra­c­tion power is available pre­cis­e­ly whe­re it is nee­ded. The ele­ments lea­ve the fac­to­ry with cut-outs for win­dows, doors or elec­tric lines at mil­li­me­ter pre­cis­i­on. To meet the­se requi­re­ments, each of the three CNC-machi­ning cen­ters pos­s­es­ses for all pro­ces­sing steps a pro­ven 5‑axis unit with access to a tool chan­ger with 30 places. This is roun­ded off by a deep-dril­ling unit for holes in the edge up to 1,800 mm in depth. 

High degree of prefabrication with through-feed system

Regnauer Fertigbau GmbH & Co. KG

The Chiem­gau-based com­pa­ny Reg­nau­er Fer­tig­bau GmbH pro­du­ces house walls and cei­lings with a high degree of pre­fa­bri­ca­ti­on. Modern auto­ma­ti­on tech­no­lo­gy domi­na­tes many pro­duc­tion steps. Ever sin­ce its smooth inte­gra­ti­on into the exis­ting pro­duc­tion line, our high­ly effi­ci­ent ECO-3313‑A through-feed sys­tem has been a cen­tral com­po­nent of the over­all pro­cess. An area sto­rage sys­tem with 14 places pre­ce­des it, whe­re the arran­ge­ment of the panel stacks is in line with the quan­ti­ties requi­red, mea­ning that the panel types most often nee­ded are clo­sest to the mil­ling machi­ne. A fle­xi­ble grip­per sys­tem moves raw panels with maxi­mum dimen­si­ons of 3.300 x 1.280 x 25 mm and trans­ports them into the CNC unit via a motor-dri­ven rol­ler con­vey­or. Then, five posi­tionable grip­pers ali­gned along the table on a slide hold the panel in place. The sec­tio­ning and cut­ting to size of the panel are the next steps. 

Timber construction with a future

Renggli AG

The Renggli plant in Switz­er­land ful­ly meets the needs of deman­ding con­s­truc­tion part­ners in terms of pro­ces­ses, fle­xi­bi­li­ty and per­for­mance. The skil­led craft­smen at Renggli have strong allies in their high-tech machi­nes. For exam­p­le, the ECO-3533-B-Sprint panel pro­ces­sing cen­ter from Rei­chen­ba­cher Hamu­el, which per­mits lar­ge panels to be pro­ces­sed on both sides and has a ful­ly auto­ma­tic loa­ding system.

The prin­ci­ple is quite simp­le: small panels for small are­as, lar­ge panels for lar­ge are­as. While small panels hard­ly cau­se any pro­blems, lar­ge panels can pre­sent pro­duc­tion com­pa­nies with major chal­lenges. Here, the ECO from our machi­ne port­fo­lio, which has been spe­ci­al­ly adapt­ed to cus­to­mer requi­re­ments. comes in to fill the gap in lar­ge-for­mat pro­duc­tion. The cut­ting sys­tem is able to pro­cess panel sizes of up to 3,300 × 7,000 mm. Even for uncon­ven­tio­nal pla­te for­mats, all of this hap­pens ful­ly auto­ma­ti­cal­ly in a sin­gle work step direct­ly after the pro­vi­si­on of the digi­tal data. A 40-fold dril­ling unit makes com­plex spe­cial and row dril­ling chil­d’s play, while a 5‑axis work spind­le is available for fast saw set-ups.

State-of-the-art technology

neuform-Türenwerk Hans Glock GmbH & Co. KG

The Neu­form team was loo­king for a com­pre­hen­si­ve yet cost-effec­ti­ve pro­duc­tion solu­ti­on for doors from batch size 1 with short set-up times. Here, cont­act was made with a Dutch cus­to­mer who offe­red three iden­ti­cal Rei­chen­ba­cher VISION-II-UT sys­tems with gan­try loa­ders for sale. This brought the rea­liza­ti­on of the Neu­form idea within reach.

The U‑shaped por­tal struc­tu­re of each of the three iden­ti­cal VISION-II-UT sys­tems fea­tures two car­da­nic 5‑axis units, which allows a gre­at varie­ty of vari­ants thanks to the pos­si­bi­li­ty of choo­sing bet­ween par­al­lel and sin­gle machi­ning. A 60-place chain tool maga­zi­ne sup­ports the tool chan­ge of both units during machi­ning. The through-feed table is equip­ped with a dri­ven rol­ler track with lif­ting device. Moreo­ver, the­re is a fixed suc­tion bar at the front, and a mobi­le one at the rear, which can be adjus­ted via the NC axis and is equip­ped with indi­vi­du­al­ly con­troll­able vacu­um cups and posi­tio­ning stops.

Change through technology

Brüninghoff Group

The ECO-8126‑A mark­ed the begin­ning of a new era of pro­cess-ori­en­ted thin­king at Brü­ning­hoff in the field of panel cut­ting. The goal was a ful­ly auto­ma­ted pre­fa­bri­ca­ti­on pro­cess that seam­less­ly inte­gra­ted sto­rage, fee­ding, cut­ting, pro­ces­sing, and stack­ing. With panel for­mats up to 8 × 2.5 m and weights up to 800 kg, this requi­red a robust solu­ti­on: The sta­tio­na­ry gan­try sys­tem has a mobi­le pro­ces­sing table with a grid-pat­ter­ned HPL table sur­face and a sound­pro­of cabin to opti­mal­ly meet the requi­re­ments for sta­bi­li­ty, pre­cis­i­on, and working environment.

The tech­no­lo­gy takes into account the wide ran­ge of mate­ri­als used, inclu­ding chip­board, OSB, MDF, cement-bond­ed chip­board, gyp­sum fiber­board and plas­ter­board, HPL and three-lay­er boards, lami­na­ted veneer lum­ber, and soft­wood fiber­board. The pro­ces­sing stra­tegy defi­nes the exact pro­cess sequence, inclu­ding tool use, the order of pro­ces­sing per panel, and the use of label and inkjet prin­ters for part mar­king. Nine varia­ble stack­ing sta­ti­ons ensu­re opti­mal cut­ting results; the stack­ing sequence is careful­ly plan­ned so that the sub­se­quent ele­men­ta­ti­on can be car­ri­ed out quick­ly. The sys­tem is desi­gned for for­mat­ting around 140,000 m² of panels per year, depen­ding on the com­ple­xi­ty of the machi­ning operations.

Panel processing with intelligent automation

Terhalle Holzbau GmbH

At Ter­hal­le in Ahaus, all panels in tim­ber con­s­truc­tion are pro­ces­sed ful­ly auto­ma­ti­cal­ly by the VISION-III‑U and machi­ned to order. The sophisti­ca­ted picking sys­tem uses buf­fer sto­rage for panel sort­ing so that all parts are always available in the cor­rect order for down­stream processes.

In 80 per­cent of cases, three to four com­pon­ents are pro­du­ced from one panel, as Ter­hal­le only uses panel sizes up to a maxi­mum of 3.5 × 1.25 m due to easier hand­ling and to avo­id breaka­ge. Some of the panel mate­ri­als gene­ra­te a lot of dust, which is why a con­troll­able extra­c­tion hood is instal­led to pre­vent dust explo­si­ons and ensu­re first-class sur­face qua­li­ty for dust-sen­si­ti­ve pro­ducts. Dif­fu­se, porous mate­ri­als such as soft wood fiber­board are relia­bly fixed in place using vacu­um tech­no­lo­gy. The machi­ne con­cept with a 3- and 5‑axis unit, which work alter­na­te­ly, mini­mi­zes tool chan­ge times and increa­ses pro­duc­ti­vi­ty and flexibility.

Intel­li­gent auto­ma­ti­on and seam­less data com­mu­ni­ca­ti­on bet­ween upstream and down­stream sys­tems ensu­re a con­ti­nuous pro­duc­tion flow. Lot size 1 pro­duc­tion is par­ti­cu­lar­ly valued in com­plex con­s­truc­tion projects.
