Abstract

The present invention relates to a method for machining blanks of wood, plastic or similar material (7) in the manufacture of doors, for instance, or other building elements, furniture, etc. in which the blank is secured to a work table (8) and machining is performed with the aid of machining tools (5), such as milling tools, and in which the work table (8) with the blank (7) is placed in substantially vertical position. The invention is characterised in that machining is performed in this position and that a channel (6) is placed under the work table (8) to collect shavings, etc. from the machining, said channel being provided with means, e.g. a worm conveyor (6), for transporting this material away.

Description

501 849 don för avtransport av detta material, exempelvis en spàntransportskruv, varvid spàn etc, avtransporteras medelst denna. Detta innebär, att nagot egentligt behov av sug- fläktar, borstning ej finnes, utan att spànen försvinner fràn arbetsbordet och enkelt avtransporteras till lämpligt ställe med ett minimalt behov av energi och under miljömässigt acceptabla former. 501 849 means for transporting this material, for example a chip transport screw, whereby chips etc. are transported by means thereof. This means that there is no real need for suction fans, brushing, but that the chips disappear from the work table and are easily transported to a suitable place with a minimal need for energy and in environmentally acceptable forms.

Ritningar: Uppfinningen är närmare exemplifierad i bifogade figurer, av vilka figur 1 visar en anordning för utförande av sättet, sedd från sidan, och figur 2 detsamma, sedd framifrån.Drawings: The invention is further exemplified in the accompanying figures, of which figure 1 shows a device for carrying out the method, seen from the side, and figure 2 the same, seen from the front.

Utföringsexempel: I figurerna visas ett i huvudsak vertikalt placerat arbetsbord (8). Maskinen består av ett stativ, där ett verktyg (5) kan röra sig i tre dimensioner / axlar X,Y,Z, numeriskt (CNC) styrt från ett dator/detaljprogram. En slid (1) löper på horisontella balkar (2), så arrangerade, att ett i huvudsak vertikalt plan bildas för för bearbetning av arbetsstycket (minst 45 graders vinkel mot horisontalplanet).Exemplary embodiment: The figures show a substantially vertically placed work table (8). The machine consists of a stand, where a tool (5) can move in three dimensions / axes X, Y, Z, numerically (CNC) controlled from a computer / detail program. A slide (1) runs on horizontal beams (2), so arranged that a substantially vertical plane is formed for machining the workpiece (at least 45 degrees angle to the horizontal plane).

Pá sliden (1) med rörelseriktning i Y-led (fig 2) löper en tvärslid (3) med rörelseriktningen definierad som X-led enligt fig 2. Nämnda slid uppbär en spindelenhet (4) och verktyg (5) med rörelseriktning i Z-led (se fig 1).On the slide (1) with movement direction in Y-direction (Fig. 2) runs a transverse slide (3) with the direction of movement defined as X-joint according to Fig. 2. Said slide carries a spindle unit (4) and tools (5) with movement direction in Z- direction led (see Fig. 1).

Maskinen, som är helt inkapslad, har i sin undre del en spànskruvtransportör för uttransport av spàn, trämjöl eller liknande från bearbetningen och från en ränna under arbetsbordet (se fig 2).The machine, which is completely encapsulated, has in its lower part a chip screw conveyor for transporting chips, wood flour or the like from the processing and from a chute under the work table (see fig. 2).

V; 501 849 För fastspänning av arbetsstycken (7) är i maskinen arbetsbordet med fixturskenor så arrangerat (8), att förflyttning i Y-led kan göras med hjälp av sliden (1) och pá fixturskenorna monterade och automatiskt frán CNC- programmet manövrerbara medbringartappar (9), passande mot i sliden (1) monterade fästen (10).V; 501 849 For clamping workpieces (7), the work table with fixture rails is arranged in the machine in such a way (8) that movement in Y-direction can be made by means of the slide (1) and on the fixture rails mounted and automatically maneuverable drive pins (9 ), suitable for mounts (10) mounted in the slide (1).

Vid bearbetning av arbetsstycken (ämnen) i lätt bearbetbart material, sàsm trä, gips, plast etc. i visat läge faller det mesta av bearbetningsspánen, mjöl etc ner under bordet till en ränna, och transporteras bort av transportörskruven (4). Bordet kan inställas i olika vinklar. men det väsentliga är, att det är i huvudsak vertikalt, så att spàn etc. faller ner som visats. Ämnet (7) kan fästas vid fixturskenorna medelst vakuumsugning, magnetisk infästning, fastspänning etc. Sättet enligt uppfinningen kan varieras på màngahanda sätt inom ramen för nedanstående patentkrav.When machining workpieces (blanks) in easily machinable material, such as wood, plaster, plastic, etc. in the position shown, most of the machining chips, flour, etc. fall under the table into a gutter, and are transported away by the conveyor screw (4). The table can be set at different angles. but the essential thing is that it is essentially vertical, so that the chips etc. fall down as shown. The blank (7) can be attached to the fixture rails by means of vacuum suction, magnetic attachment, clamping, etc. The method according to the invention can be varied in many ways within the scope of the following claims.

Claims

501 849 P A T E N T K R A V.

1. '1. Methods for working with blanks of wood, plastic and similar materials (7), for example in the manufacture of doors or other building elements, furniture, etc., wherein the blank is attached to a work table (8) and the machining is done by machining tools (5 ), such as milling cutters, and where the work table (8) with the blank (7) is placed mainly in a vertical position, i.e. at least 45 degrees fixed angle to the horizontal plane, characterized in that the machining takes place in this position, and that the work table (8) is provided with a number of fixture rails (8), to which the blank is attached, for example by vacuum suction, magnetic attachment, clamping, etc., the fixture rails (8) being adjusted to the shape of the blank (7), for example automatically by numerical control (CNC) of carrier means (9, 10).

2. A method according to claim 1, characterized in that under the set-up work table is placed a lateral groove (6) for chips etc. from the processing, which groove is provided with means for transporting this material, for example a Spanish screw conveyor.
