_In_un a_dispos i z ione__no_t a?di_ questo tipo, sul lato _ della macchina su cui si trovano i mandrini _ di te_no4 natura, e la sega di taglio, ? disposto un tavolo a rull i che. riceve _i pezzi da lavorare e dal quale, dopo il taglio e la formazione dei tenoni e delle mortase, 1 pezzi vengono trasferiti ai mandrini di profilatura longitudinale al termine della corsa di lavoro del tavolo a rulli. E* anche nota una disposizione, in cui l'estremit? finora non lavorata del pezzo, dopo la profilatura longitudinale, viene munita di tenoni e mortase. In questa disposizione il pezzo profilato longitudinalmente viene trasportato su un ulteriore tavolo a rulli che fa passare l 'estremit? posterior del pezzo davanti ad almeno un altro mandrino tenon atore. _In_a_device__no_t a? Of_ this type, on the side _ of the machine on which the technical spindles _ are located, and the cutting saw,? arranged a roller table. receives the pieces to be machined and from which, after cutting and forming the tenons and mortises, the pieces are transferred to the longitudinal profiling spindles at the end of the working stroke of the roller table. A disposition is also known, in which the extremity? previously unworked of the piece, after longitudinal profiling, it is fitted with tenons and mortises. In this arrangement, the longitudinally profiled piece is transported onto a further roller table which passes the end? posterior of the workpiece in front of at least one other tenon spindle.

L'invenzione si pone il compito di sviluppare un ^ macchina per la lavorazione del legno del tipo cita all'inizio, in modo che la profilatura longitudinal venga effettuata solo nel caso in cui i legni per.; telai " da finestra siano muniti su due lati di tenoni e mortase. Contemporaneamente viene accelera il decorso di lavoro . The invention has the task of developing a woodworking machine of the type mentioned at the beginning, so that the longitudinal profiling is carried out only in the case in which the woods for. window frames are fitted on two sides with tenons and mortises. At the same time, the work process is accelerated.

Questo compito, viene risolto secondo...! ' invenzion per il fatto che a monte dell 'unit? costituita d.a sega di taglio e mandrini di tenonatura, sistemata monte del o dei mandrini di profilatura longitudina ? disposta, nel senso di lavoro, una unit? supplente tare, pure costituita da una sega di taqlio e da al meno un mandrino tenonatore, il cui lato di lavoro opposto a quello della prima unit?, le due unit? es sendo disposte in allineamento longitudinale o in p ver ~ticali " paralleli e tra le du "e unit? essendo p ~rev sto un trasportatore trasversale che lavora ad ango retto rispetto ad esse, e che sposta il legno da te da. lavorare, dopo la tenonatura e la mortasatura pe mezzo dell 'unit? supplementare, nella sua direzione longitudinale fino a che l 'estremit? del legno da telaio munita di tenoni e mortase giace in un piano verticale-che corrisponde alle dimensioni. previste del' pezzo e in cui pu? essere lavorato dalla prima unit?. This task is solved according to ...! 'invention due to the fact that upstream of the unit? consisting of a cutting saw and tenoning spindles, arranged upstream of the longitudinal profiling spindle (s)? willing, in the sense of work, a unit? alternate tare, also constituted by a cutting saw and by at least a tenoning spindle, whose working side opposite to that of the first unit, the two units? being arranged in longitudinal alignment or in vertical "parallel and between the two" and units? p ~ rev being a transversal conveyor which works at an angle to them, and which moves the wood away from you. work, after tenoning and mortising by means of the unit? additional, in its longitudinal direction until the extremity? of the tenon and mortise loom wood lies in a vertical plane - which corresponds to the dimensions. expected of the piece and in which can? be worked by the first unit.

Con questa disposizione si ottiene che, nel deeo della lavorazione, dapprima un lato frontale .del l gno da telaio viene tagliato e munito di tenoni e m tase, e successivamente il legno da telaio viene sp stato nella sua direzione longitudinale nel modo de scritto dal trasportatore trasversale in modo che i .secondo_lato_?rontale_possa_essere? t.agliat?? e_munito di_tenoni- e-mor.t ase.. _Solo_ allora._awiene_i:i ? .trasfer?-. mento _ad_angolo?sui_mandrini_di_pro?.il.atur.a-longi?u4._ dinal.e_._- Con_ci?_dire.tt.ament.e_dopo? l.a_profilatura_longi-_ -.tuidinal.e__p.u0_essere?tagliat.a_anche_i.a_.lista_di?vetro..._ ,_ L.a_dis.po_sizione_s.eco.ndo_l_Linvenzione__ha_q.uindi_i: vantaggio^. che , _Q1 t re. all 1 accelerazi o.ne_del_ c i c lo. _di lavoro f si possono staccare dai legni_di_telaio__diret? t amente dopo _1 a profilatura longitudinale, in un uni I? co ciclo, le liste di vetro necessarie e che vengono 1 _ a_maneare ulteriori esigenze intermedie di ima sega per liste di vetro o simili? With this arrangement it is obtained that, in the process of processing, first a front side of the loom wood is cut and fitted with tenons and miter, and subsequently the loom wood is pressed in its longitudinal direction in the manner described by the conveyor. transverse so that the second_side_? rontal_can_be? t.agliat ?? e_munito di_tenoni- e-mor.t ase .. _Only_ then._awiene_i: i? .transfer? -. ment _ad_angle? sui_mandrini_di_pro? .il.atur.a-longi? u4._ dynal and _._- Con_ci? _dire.tt.ament.e_after? l.a_profilatura_longi-_ -.tuidinal.e__p.u0_be? cutt.to_also_i.a_.list_of? glass ..._, _ L.a_dis.po_sizione_s.eco.ndo_l_Invention__ha_q.uindi_i: advantage ^. that, _Q1 t re. all 1 acceleration. _of work f can they be detached from the wood_of_frame__diret? t after _1 a longitudinal profiling, in a uni I? with the cycle, the necessary glass slats and which are created for further intermediate requirements of a saw for glass slats or the like?

E? pertanto vantaggioso se, _ a valle dei mandrini di profilatura longitudinale, nel senso di lavoro, viene disposta una sega per liste di vetro._ AND? therefore it is advantageous if, downstream of the longitudinal profiling spindles, in the working direction, a saw for glass strips is arranged.

In modo opportuno alle due unit? per la troncatura, rispettivamente il taglio del legno da telaio e per 1 a t enonatura - pu? essere associato volta per volt a un tavolo a rulli con il quale il legno da telaio da lavorare viene fatto passare davanti all'unit? e trasportato alla successiva stazione. In an appropriate way to the two units? for the truncation, respectively the cut of the wood from the frame and for 1 to t enonatura - pu? be associated each time with a roller table with which the wood to be processed is passed in front of the unit? and transported to the next station.

E* particolarmente?.v?ntaggioso.,se^questo t?volo?a < rulli viene sostituito da un trasportatore in cui, tra in trasportatore superiore e un trasportatore inferrore i pezzi da lavorare vengono fissati in posizione alline.ata_e cos? trasportati- volta-per- volta al-la-s It is particularly advantageous if this roller system is replaced by a conveyor in which, between the upper conveyor and a lower conveyor, the workpieces are fixed in an aligned position. transported-time-to-time to-the-s

La regola ione dell' arresto pu? essere effettuata da una cin entata e l ' arresto pu? essere fissato in diverse p ioni di regolazione prestabilite da un comando ele Esiste inoltre la possibilit? di munire l ' arrest i pinze o simili e di impiegarlo quindi come trasp ore trasversale per il legno da telaio? , 11 conveyor t ras ver sale- pu? Is there a neutral conveyor or from a slider which is positioned on the transport surface the piece in the transverse direction. It is particularly appropriate if in the transverse carrier area? expected a real stop and corresponding to the different longitudinal dimensions of the wood to be processed? The rule ion of the arrest can? be carried out by a cin ent and the arrest can? be fixed in different regulation pions pre-established by a command ele. There is also the possibility? to equip the stop with pliers or the like and to use it as a transversal transp oration for loom wood?

Il trasferimento angolare tra la prima unit? e i andrini di profilatura longitudinale pu? avvenire articolare in modo di per s? noto per abbassamento ei primi rulli di avanzamento, nel senso di lavoro ssociati ai mandrini di profilatura longitudinale . La disposizione secondo^l 'invenzione rende anche articolarmente possibile <completare' la profilatura ongitudinale per il fatto che sul lato opposto all erie di mandrini di profilatura longitudinale, preeribilmente all 'estremit? di questa serie, sono di^telaio -da_la'vorare_Mf._do.po-la-_tenonatura_e_la_mor-tjasa--tur..a,_per_mez zo^dellluni t ?_supplement ar.e_9 -nella. sua ? _ di re z ione_longitudinale_c io ?_nel _s.enso dell.a. freccia The angular transfer between the first unit? and the longitudinal profiling andrini pu? future articulate in a way per se? known for lowering and the first feed rollers, in the working direction, associated with the longitudinal profiling spindles. The arrangement according to the invention also makes it possible to complete the longitudinal profiling in an articulated manner due to the fact that on the opposite side to the longitudinal profiling mandrels, preferably at the extremity? of this series, they are of ^ frame -da_la'vorare_Mf._do.po-la-_tenonatura_and_la_mor-tjasa - tur..a, _per_mez zo ^ dellluni t? _supplement ar.e_9 -in. her ? _ in the sense of the a.y. arrow

la figura 2 ? una vista corrispondente alla figui 1 di una variante di forma d'esecuzione. figure 2? a view corresponding to Figure 1 of a variant of embodiment.

Secondo la figura 1 la macchina pe#La lavorazione del legno presenta una serie di mandrini 1 , che servono per ricevere utensili per la profilatura longit dinaie ?- A monte di .questa' serie di mandrini di profi latura longitudinale ? disposto trasversalmente, nel senso di lavoro, un mandrino 2 tenonatore a monte de le ? ancora disposta una sega di taglio? According to Figure 1, the woodworking machine has a series of spindles 1, which serve to receive tools for longitudinal profiling. arranged transversely, in the working direction, a tenoning mandrel 2 upstream of the? still arranged a cutting saw?

Il pezzo da lavorare (o i pezzi da lavorare nel caso che debbano essere lavorati contemporaneament pi? pezzi di uguale lunghezza) viene fissato sul t volo a rulli 12 dell'unit? supplementare 9, e vien fatto passare, per mezzo del tavolo a rulli 12, da ti alla prima sega di taglio 10, l'estremit? tronc essendo munita successivamente dal mandrino tenona r^11 di tenoni e mortase. Il tavolo a rulli 12 fa sare successivamente il pezzo sul trasportatore tr s versai e 13, il quale, per esempio, pu? trovarsi n posizione di partenza rappresentata con linea a tr dopo di che, per mezzo del trasportatore trasversa 13f il pezzo 14 viene spostato nel senso della fre 15 fino a che urta contro l'arresto 17. In questa sizione, esso viene trasferito sul tavolo a rulli della seconda unit? 7 e da questa fatto passare da vanti alla sega di taglio 3 e al relativo mandrino tenonatore 2 di questa seconda unit? 7. Con ci?, a la seconda estremit? del legno per telaio ? munita di tenoni e mortase. Successivamente, a partire da posizione d'estremit? descritta del tavolo a rulli abbassando l 'unit? di rulli di avanzamento 5a anter re nel senso di lavoro, il pezzo viene afferrato d questa unit? a rulli di avanzamento e alimentato ai mandrini 1 di profilatura longitudinale, in modo ch ora esso viene profilato su questo lato rivolto vers mandrini 1 di profilatura longitudinale? Poich? il p ? gi? munito sui due lati di tenoni e mortase, pu? e anche alimentato subito successivamente alla sega 4 liste di vetro in modo che anche la lista di vetro p essere subito separata via. Qualora sia necessaria u profilatura longitudinale sul lato opposto si posson sporre ulteriori mandrini 18 di profilatura longitud che sono diretti con il loro lato di lavoro in senso sto ai mandrini 1 di profilatura longitudinale, all* nit? della serie formata di mandrini 1 di profilatur gitudinale, il primo dei mandrini 18 di profilatura tudinale potendo essere opposto alla sega per liste tro 4. In questo modo si risparmia spazio, particola te nei casi in cui sia necessario, rispettivamente v impiegato un unico mandrino 18 di profilatura longit La figura 2 mostra una forma di esecuzione un p? variata in cui i tavoli a rulli 12 e 8 delle unit? 7 e 9 secondo la forma di esecuzione della figura 1 sono sostituiti da trasportatori di pinze 19 e 20 che sono costituiti in modo di per s? noto da un tra sportatore superiore e da un trasportatore inferiore tra i quali vengono bloccati i pezzi da trasportare. Come rappresentato, questi trasportatori possono ess re costituiti da singoli nastri 21 che giacciono l 'u The piece to be machined (or the pieces to be machined if several pieces of equal length are to be machined at the same time) is fixed on the roller flight 12 of the unit. 9, and is made to pass, by means of the roller table 12, from ti to the first cutting saw 10, the end? tronc being subsequently fitted with tenons and mortises by the tenon mandrel r ^ 11. The roller table 12 then causes the piece to be placed on the transverse conveyor 13, which, for example, can? be in the starting position represented by a tr line, after which, by means of the transverse conveyor 13f, the piece 14 is moved in the direction of the stop 15 until it hits the stop 17. In this position, it is transferred to the table at rollers of the second unit? 7 and passed from this to the cutting saw 3 and the relative tenoning spindle 2 of this second unit? 7. With this, at the second end? some wood for the frame? equipped with tenons and mortises. Subsequently, starting from the extreme position? described of the roller table by lowering the unit? of feed rollers 5a front in the working direction, the piece is gripped by this unit? feed rollers and fed to the longitudinal profiling spindles 1, so that it is now profiled on this side facing towards the longitudinal profiling spindles 1? Since? the P ? already? equipped on both sides of tenons and mortises, can? and also fed immediately afterwards to the saw 4 glass strips so that the glass strip can also be immediately separated away. If longitudinal profiling is required on the opposite side, further longitudinal profiling spindles 18 can be arranged which are directed with their working side in the direction of the longitudinal profiling spindles 1, all the way. of the series formed of longitudinal profiling spindles 1, the first of the tudinal profiling spindles 18 being able to be opposed to the slat saw 4. In this way space is saved, particularly in cases where a single spindle is required or used 18 of profiling longit Figure 2 shows an embodiment ap? varied in which the roller tables 12 and 8 of the units? 7 and 9 according to the embodiment of Figure 1 are replaced by gripper conveyors 19 and 20 which are constituted in a per se? known from an upper conveyor and a lower conveyor between which the pieces to be transported are clamped.

SUMMARY

In a woodworking machine, for the tenoning and longitudinal profiling of pieces of wood, in particular wood for frames, with at least a first spindle with tenoning tools and cutting saw placed upstream, which? arranged obliquely to at least a second spindle with tools for longitudinal profiling, the pieces of wood equipped on a front side with tenons and mortises being transferred, at right angles to the direction of movement in progress, to spindles for longitudinal profiling, profiling longitudinal, with

only when the wood for looms are fitted on both sides with tenons and mortises?

There? is obtained according to the invention due to the fact that upstream of the unit? consisting of a cutting saw and tenoning spindle, placed upstream of the o

of the longitudinal profiling spindles, 6 arranged, in the working direction, a unit? additional, also consisting of a cutting saw and at least one tenoning mandrel, the working side of which? opposite to that of the first unit ?, the two units? being arranged in longitudinal alignment or in parallel vertical planes and between the two units? a transversal conveyor being provided which works at right angles to them and which moves the frame wood to be worked after tenoning and mortising by means of the unit? additional until the end? of the window frame, not equipped with tenon and mortise, lies in a vertical plane that corresponds to the predetermined dimensions of the piece and in which it can? be worked by the first unit? (Figure 1).

Does the invention relate to a machine for working wood, for tenoning and longitudinal profiling of wooden parts? in particular for window frames with at least a first spindle with tenoning tools and cutting saw arranged upstream, which? arranged obliquely to at least a second condensile mandrel for longitudinal profiling.

the wooden parts placed on a front side of tenons and mortises being transferred at right angles, with respect to their direction of movement in progress, to the spindles for longitudinal profiling.

In a known arrangement of this type, on the side of the machine on which the tenoning mandrels and the cutting saw are located,? arranged a roller table which receives the pieces to be machined and from which, after cutting and forming the tenons and mortises, the pieces are transferred to the longitudinal profiling spindles at the end of the working stroke of the roller table. A disposition is also known, in which the extremity? previously unworked of the piece, after longitudinal profiling, it is fitted with tenons and mortises. In this arrangement, the longitudinally profiled piece is transported onto a further roller table which passes the end? of the workpiece in front of at least one other tenoning spindle.

The invention aims to develop a woodworking machine of the type mentioned at the beginning, so that the longitudinal profiling is carried out only in the case in which the woods for window frames are equipped on two sides with tenons. and mortise. At the same time the course of work is accelerated.

This task is solved according to the invention due to the fact that upstream of the unit? consisting of a cutting saw and tenoning spindles, arranged upstream of the longitudinal profiling spindle (s)? willing, in the sense of work, a unit? additional, also consisting of a cutting saw and at least one tenoning mandrel, the working side of which? opposite to that of the first unit ?, the two units? being arranged in longitudinal alignment or in parallel vertical planes and between the two units? a transversal conveyor being provided which works at right angles to them, and which moves the wood from the frame to be worked, after tenoning and mortising by means of the unit? additional, in its longitudinal direction until the extremity? of the wood frame equipped with tenons and mortises lies in a vertical plane that corresponds to the expected dimensions of the piece and in which it can? be worked by the first unit.

with this arrangement it is obtained that, in the course of processing, first one front side of the frame wood is cut and fitted with tenons and mortises, and then the frame wood is moved in its longitudinal direction in the manner described by the transverse conveyor so that the second front side can be cut and fitted with tenons and mortises, only then can the angle transfer take place on the longitudinal profiling spindles. With us? directly after the longitudinal profiling pu? the glass slate also be cut.

The arrangement according to the invention therefore has the advantage that, in addition to accelerating the work cycle, the necessary glass strips can be detached from the wood frame directly after the longitudinal profiling, in a single cycle, and that further intermediate needs of a saw for glass strips or the like.

It is therefore advantageous if, downstream of the longitudinal profiling mandrels, in the working direction, a saw for glass strips is arranged.

in a suitable way to the two units for the truncation, respectively the cutting of the wood from the frame and for the tenoning> pu? be associated each time with a roller table with which the wood from the frame to be processed is passed in front of the unit? and transported to the next station?

Is it particularly advantageous if this roller table is replaced by a conveyor in which, between an upper conveyor and a lower conveyor, the pieces to be machined are fixed in an aligned position and thus transported each time to its next station and transferred thereto?

The cross conveyor can? consist of a conveyor belt or a slider that moves the piece across a transport surface in a transverse direction? Is it particularly appropriate if in the area of the cross conveyor? provided an adjustable stop corresponding to the different longitudinal dimensions of the wood for the frame to be processed? The adjustment of the stop can? be carried out by a toothed belt and the stop can? be fixed in different adjustment positions preset by an electronic control? There is also the possibility? to arm the stop

of pliers or similar and therefore to use it as a transporter for frame wood?

ZI angular transfer between the first unit? and 1 longitudinal profiling spindles can? particularly take place in the way of per se? known for abbassaaento

of the first feed rollers, in the working direction, associated with the longitudinal profiling spindles?

The arrangement according to the invention also makes it particularly possible to complete the longitudinal profiling due to the fact that on the side opposite the series of longitudinal profiling spindles, preferably at the end? of this series, are there other longitudinal profiling spindles? whose working side is opposite to that of the first longitudinal profiling nandri ni and with which one can? to profile the opposite side of the frame wood in one pass? At least the first of these longitudinal profiling spindles can? be arranged relative to the glass strip saw so that a substantial additional footprint is not required?

With such a provision you can? to finish working on all sides, in a cycle, a loom wood? The invention is illustrated more? in detail below, in relation to implementation examples? in the drawings where:

Figure 1 shows a schematic plan view of an embodiment of the woodworking machine according to the invention;

Figure 26 is a view corresponding to Figure 1 of a variant embodiment;

According to FIG. 1, the woodworking machine has a series of spindles 1 which spread out to receive tools for longitudinal profiling? Upstream of this series of longitudinal profiling spindles? arranged transversely, in the working direction, a tenoning mandrel 2 upstream of which? still arranged a cutting saw?

Downstream of the longitudinal profiling spindles 1? arranged, in the working direction, a saw 4 for glass strips and furthermore advancement groups 5 indicated by dashed lines are fixed to the longitudinal profiling spindles 1.

L * unit? 7 consisting of the tenoning spindles 2 and the cutting saw 3 also equipped with a roller table 8 which passes the pieces fixed on it both in front of the cutting saw 3 and in front of the tenoning spindle 2. This roller table 8 has a position of extremity? in which the piece already? equipped with tenons? mortise can be transported at right angles to the longitudinal profiling spindles, the end position? of the roller table corresponding to the starting position of the piece for longitudinal profiling.

Upstream of the first unit? 7, consisting of the cutting saw 3 and the tenoning spindle 2? another unit arranged? 9 which also has a cutting saw 10 and a tenoning mandrel 11, as well as a roller table 12. As shown, the two units? 7 and 9, are arranged in parallel vertical planes, between the two units? 7 and 9 being provided a transversal conveyor 13 which works at right angles to these vertical planes and which moves the wood from the frame to be worked 14 * after tenoning and mortising, by means of the unit? supplement 9 in its longitudinal direction that is? in the direction of the arrow

15, until the end? rear 14a of the wood

from frame 14 not equipped with tenons and mortises, lies

in a vertical plane corresponding to the expected dimensions of the piece and in which it can? to work

with the first unit? 7?

In the area of the cross conveyor 13? that in the example of execution represented in figure 1, can? be a cursor, which moves piece 14

on a driving surface 16, can? Be expected

a stop 17 which can be moved corresponding to the different longitudinal dimensions of the loom timbers

to work, which thus determines the definitive length of the loom wood to be manufactured. The arrest

17 can be driven by a toothed belt that moves the stop relatively quickly, being able to be provided with an electronic control that gives? the respective adjustment positions for the stop in advance? Instead of the slider shown in Figure 1, the transverse conveyor 13 can? be constituted

from a conveyor belt or similar.

The mode of operation of the arrangement described? the following.

The workpiece (or the workpieces in case they are to be machined with no more pieces of equal length) is fixed on the roller table 12 of the unit. 9, and is made to pass, by means of the roller table 12, in front of the first cutting saw 10, the end? truncated being subsequently provided by the tenoning mandrel with tenons and mortises? The roller table 12 passes the piece successively on the transverse conveyor 13, which, for example, can pass. be in the starting position shown with broken lines, after which, by means of the transverse conveyor 13, the piece 14 is moved in the direction of the arrow 15 until it hits the stop 17? In this position, it is transferred to the roller table 8 of the second unit? 7 and passed by this in front of the cutting saw 3 and the relative tenoning mandrel 2 of this second unit? 7? With this, also the second extremity? some wood for the frame? equipped with tenons and mortises, successiveaente, starting from the end position? described of the roller table 8, lowering the unit? of front feed rollers 5a in the working direction, the piece is gripped by this unit? feed rollers and fed to the longitudinal profiling mandrels 1, so that it is now profiled on this side facing the longitudinal profiling mandrels 1? Since? the piece ? already? equipped on both sides of tenons and mortises, can? also be fed immediately after the saw 4 for glass slats so that even the glass slate can? be immediately separated away. If longitudinal profiling is required on the opposite side, further longitudinal profiling spindles 18 can be arranged which are directed with their working side in the opposite direction to the longitudinal profiling spindles 1, at the right side. of the formed series of longitudinal profiling spindles 1, the first of the longitudinal profiling spindles 18 being able to be opposed to the glass strip saw 4? In this way, space is saved, particularly in cases where it is necessary, respectively, when a single longitudinal profiling mandrel 18 is used.
