(74) Fuldmægtig: Patentbureauet Hofman-Bang & Boutard (54) Maskine til formning af trådbindeelementer til opslidset, rørlignende form(74) Plaintiff: Hofman-Bang & Boutard Patent Office (54) Machine for forming wire bonding elements for slotted, tube-like shape

Opfindelsen angår en maskine af den i krav l's indledning anførte art.The invention relates to a machine of the kind specified in the preamble of claim 1.

Opfindelsen tager sigte på fremstilling af bindeelementerne til den form, de findes i ved indbindings- eller bladhæftningstrinnet, dvs. j i opslidset rørform.The invention is directed to the preparation of the binding elements to the form in which they exist in the binding or leaf stitching step, i.e. j in slotted tubular form.

) £ Ved fremstillingen af sådanne elementer er det normalt først at ) give en længde tråd den såkaldte zig-zagform, i hvilken den har - form af en plan kam af vilkårlig længde, hvis tænder er lukket i * m \ 2 146375 spidsen og åbne ved deres rod, hvor de er forbundet med nabotænderne med flugtende trådstykker, som danner kammens ryg således, at bredden af tænderne svarer til bredden af perforeringerne i bladene, der skal sammenhæftes. En lang længde af en sådan kam gives derefter form som et opslidset rør ved passende bukning af tænderne.In the manufacture of such elements, it is usually first to give a length of thread the so-called zig-zag shape in which it has - the shape of a flat comb of any length, the teeth of which are closed at the tip and open. at their root, where they are joined to the neighboring teeth by fleeting threads forming the ridges of the comb such that the width of the teeth corresponds to the width of the perforations in the leaves to be joined. A long length of such comb is then given the shape of a slit tube by appropriate bending of the teeth.

De lukkede ender af tænderne vil nedenfor blive omtalt som "tandspidsen", og trådstykkerne vil blive omtalt som "roden" af tænderne.The closed ends of the teeth will be referred to below as the "tooth tip" and the thread pieces will be referred to as the "root" of the teeth.

I det fra britisk patentskrift nr. 447 231 kendte såkaldte Wire-O-sy-stem består bindeelementerne af trådlængder, der er bukket således, at der dannes buede kroge, på hvilke bladene er indhæftet. På det tidspunkt, indhæftningsoperationen udføres, har hvert bindeelement form af et rør med en længdeslidse i sin væg, og den afsluttende operation i indbindingsprocessen består i at lukke slidsen ved, at de lukkede ender af krogene føres ind i deres åbne ender.In the so-called Wire-O system known from British Patent No. 447,231, the binding elements consist of wire lengths bent so as to form curved hooks on which the leaves are attached. At the time the bonding operation is performed, each tying member is in the form of a tube with a longitudinal slot in its wall, and the final operation of the bonding process consists in closing the slot by inserting the closed ends of the hooks into their open ends.

I en fra britisk patentskrift nr. 492 925 kendt maskine føres trådstykket trinvis frem ved hjælp af frem- og tilbagegående arme, hvilket med hensyn til kapacitet giver et forholdsvis ringe resultat.In a machine known from British Patent No. 492 925, the piece of wire is advanced stepwise by reciprocating arms, which gives a relatively poor result in terms of capacity.

Endvidere kendes fra U.S.A.patentskrift nr. 2 874 731 en maskine, hvormed der sker en indledende formning af trådstykket ved hjælp af valser.Furthermore, from U.S. Pat. No. 2,874,731, a machine is known by means of which an initial molding of the wire piece is effected by means of rollers.

Fra U.S.A. patentskrift nr. 2 874 731 er det kendt af foretage en indledende fremføring og formning af et trådstykke ved hjælp af valser med skrueformede styreriller, og hvor den endelige formning sker ved hjælp af fire i en indbyrdes vinkel på 90° anbragte valser.From usa. U.S. Patent No. 2,874,731 is known to carry out an initial feeding and forming of a thread by means of helical guide rollers, and the final molding is effected by four rollers disposed at 90 ° to each other.

Det er opfindelsens formål at anvise en maskine af den omhandlede art, hvormed der opnås stor præcision i formningen og stor produktionskapacitet, og dette er ifølge opfindelsen opnået ved de i krav l's kendetegnende del anførte foranstaltninger.It is an object of the invention to provide a machine of the kind in which high precision in molding and high production capacity is achieved, and this is achieved according to the invention by the measures set out in claim 1.

146375 3146375 3

Opfindelsen vil blive forklaret nærmere nedenfor i forbindelse med tegningen, hvor fig. 1 viser en udførelsesform for et i kamform bukket trådstykke, fig. 2 det som et opslidset rør bukkede trådstykke, fig. 3 en udførelsesform for en maskine ifølge opfindelsen set fra oven, fig. 4 samme set fra siden, fig. 3 en vinding af en rille i maskinen, fig. 6-9 snit efter henholdsvis linierne VI-IX i fig. 4 visende de forskellige bukningstrin, og fig. 10 A,B,C tre eksempler på bearbejdningsværktøjer.The invention will be explained in more detail below in connection with the drawing, in which fig. 1 shows an embodiment of a comb-shaped piece of wire; FIG. 2 shows the piece of wire bent like a slit tube; FIG. 3 is a plan view of an embodiment of a machine according to the invention; FIG. 4 is a side view, FIG. 3 shows a winding of a groove in the machine; FIG. 6-9 sections along lines VI-IX in FIG. 4 showing the various bending steps; and FIG. 10 A, B, C three examples of machining tools.

Et trådstykke 10, fig. 1, er bukket i kamform og har tænder 14, der er lukket ved ender 16 og åbne ved rødder 18, hvor de er forbundet med tråddele 20. I den i fig. 2 viste form er tænderne bukket således, at perforerede blade kan hægtes på dem. Når dette er sket, kompletteres bindingen ved, at spidserne 16 føres ind i rødderne 18, hvilket lettes ved, at hver tand er forsynet med en indbukning 24.A thread piece 10, FIG. 1, is bent in comb form and has teeth 14 which are closed at ends 16 and open at roots 18 where they are connected to thread portions 20. In the embodiment shown in FIG. 2, the teeth are bent so that perforated leaves can be attached to them. When this is done, the binding is completed by inserting the tips 16 into the roots 18, which is facilitated by the fact that each tooth is provided with an indentation 24.

Den i fig. 3 og følgende viste maskine har et tilførselsbord 26, langs hvilket trådstykket 10 føres frem, hvorunder det føres til to trappeformede valser 28 og 30.The FIG. 3 and the following machine has a feed table 26 along which the thread piece 10 is advanced, under which it is fed to two stair rollers 28 and 30.

I valsen 28 findes en skrueformet rille 32, hvis stigning svarer til afstanden P mellem tænderne 14, fig. 1.In the roller 28 is a helical groove 32 whose pitch corresponds to the distance P between the teeth 14; First

Valsen 30 har en tilsvarende rille 32 med den samme stigning, men med modsat snoning og med den samme bredde som tænderne 14.The roller 30 has a corresponding groove 32 with the same pitch but with the opposite twist and with the same width as the teeth 14.

4 146375 Når valserne drejes i modsatte retninger, og trådstykket er i indgreb med rillerne, vil trådstykket blive ført frem over bordet 26 i sin længderetning.When the rollers are rotated in opposite directions and the thread piece engages the grooves, the thread piece will be advanced over the table 26 in its longitudinal direction.

Fig. 5 viser en vinding af rillen 32, og det ses, at rillen på et stykke S svarende til ca. en tiendedel af en cirkel er ret, d.v.s., at den ligger i et plan vinkelret på valsens akse. Når trådstykket er i indgreb med denne del af rillerne, bliver dets fremadbe-vægelse langs bordet 26 stoppet. Det er herunder formningen af en krog 12 bliver udført eller påbegyndt.FIG. 5 shows a winding of the groove 32 and it is seen that the groove on a piece S corresponding to approx. a tenth of a circle is right, i.e., it lies in a plane perpendicular to the axis of the roller. When the thread piece engages this portion of the grooves, its forward movement along the table 26 is stopped. That is, the molding of a hook 12 is performed or started.

Bordet 26 har en forlængelse 36, hvis oversidebredde aftager bort fra bordet. Når en tand 14 forlader selve bordet 26, se 10A, fig.The table 26 has an extension 36 whose upper width decreases away from the table. When a tooth 14 leaves the table 26 itself, see 10A, fig.

6, rager dens ender udenfor forlængelsen 36's sidekanter og hviler i rillerne 32 og 34 i valserne.6, its ends extend beyond the lateral edges of the extension 36 and rest in the grooves 32 and 34 of the rollers.

I delen S i den første af disse riller findes et værktøj 38, som slår mod de udragende ender og bukker dem til den i fig. 7 viste stilling, 10B i fig. 7, idet forlængelsen 36 virker som ambolt.In the portion S of the first of these grooves is a tool 38 which beats against the protruding ends and bends them to the one in FIG. 7, 10B in FIG. 7, the extension 36 acting as an anvil.

I den følgende vinding findes et værktøj 39 beliggende i større radial afstand fra valssens akse ved fortsat drejning af denne, og dette værktøj bukker tænderne til den form, der er betegnet 10C i fig. 8. Trådstykkets endelige rørform 10b frembringes med et tredie værktøj 40, fig. 8.In the following winding, a tool 39 is located at a greater radial distance from the axis of the roller by continuing to rotate it, and this tool bends the teeth to the shape designated 10C in FIG. 8. The final tubular shape 10b of the wire piece is provided with a third tool 40, FIG. 8th

Det kan tænkes, at en tand, der har passeret et værktøj, ville rette sig ud igen. Af denne grund dubbleres værktøjerne i nabovindinger, og krogene bukkes udover den ønskede slutform, til hvilken de da fjedrer tilbage.It is conceivable that a tooth that has passed a tool would straighten out again. For this reason, the tools are doubled in neighboring windings and the hooks are bent beyond the desired final shape, to which they then spring back.

Det er vigtigt, at det zig-zagformede trådstykke flugter nøjagtigt langs bordet, når det ankommer til valserne. PÅ bordet er der derfor anbragt et styr 50, fig. 3.It is important that the zig-zag-shaped piece of wire aligns exactly along the table when it arrives at the rollers. A guide 50 is therefore placed on the table, fig. Third

I hver rille er der desuden anbragt en knast 52, fig. 6, således, at den kommer til anlæg mod ydersiden af hver tand, lige før den 146375 5 bukkes. Da værktøjerne 38 er anbragt således på valserne 28 og 30, at de rammer tandspidserne 16 og rødderne 18 samtidigt, vil knasterne på modstående valser komme til anlæg med trådstykket samtidigt. Knasterne 52 vil, når de ér indstillet til den nøjagtige bredde af trådstykket, holde dette centreret på ambolten.In addition, in each groove is arranged a cam 52, fig. 6, so that it comes into contact with the outside of each tooth, just before it bends. Since the tools 38 are positioned so on the rollers 28 and 30 that they simultaneously strike the tooth tips 16 and the roots 18, the knobs on opposite rollers come into contact with the thread piece simultaneously. The lugs 52, when adjusted to the exact width of the thread piece, will keep this centered on the anvil.

For at værktøjerne 38, 39 og 40 kan arbejde korrekt på den midterste del af tænderne, bliver denne del fastholdt med en modhold 44, fig. 4, som på passende tidspunkter klemmer trådstykke't mod ambolten 36, efter at trådstykket er centreret med knasterne 52.In order for the tools 38, 39 and 40 to work correctly on the middle part of the teeth, this part is retained with a retaining 44, fig. 4, which at appropriate times clamp the thread piece against the anvil 36 after the thread piece is centered with the lugs 52.

Modholdet 44 kan svinge om en tap 60 og bevæges til klemmestilling med en excentrik 60, der drives af valserne 28 og 30. En følgevægtstang 63, der virker på et indstilleligt stop 64 på den frie ende af modholdet 44, trykkes mod excentriken 60 af en fjeder 65.The resistor 44 can pivot about a pin 60 and move to the clamping position with an eccentric 60 driven by the rollers 28 and 30. A guide rod 63 acting on an adjustable stop 64 on the free end of the resistor 44 is pressed against the eccentric 60 by a spring 65.

Modholdet 44 har et fremspring 46, fig. 9, som tjener til at forme de ovenfor i forbindelse med fig. 2 omtalte indbukninger 24 i tænderne, og som samvirker med en forsænkning 47 i ambolten 36. På den nævnte måde formes det plane zig-zagtrådstykke til det i fig.The resistor 44 has a projection 46, FIG. 9, which serves to shape the above in connection with FIG. 2, which bends 24 in the teeth and cooperates with a recess 47 in the anvil 36. In the said way, the planar zig-zag wire piece is formed into that of FIG.

2 viste rørlignende organ og føres langs bordet 26 alene med en roterende mekanisme.2 is guided along the table 26 by a rotating mechanism alone.

Værktøjerne kan være udformet på forskellig måde. Fortrinsvis indrettes de således, at de udøver et gradvist voksende tryk på de dele, der skal bukkes. De kan f.eks. være udformet som ruller eller de kan have form som knaster af enhvert ønsket profil. Da de er udsat for slid, bør de fremstilles af hærdet materialet og anbringes således, at de let kan udskiftes. Nogle eksempler på værktøjer er vist i fig. 10. Ved A i denne figur er værktøjet et hærdet stålstykke, der er indsat i en slidse 66 og er fastholdt med en skrue 66. Ved B er værktøjet en roterende knast eller excentrik. Ved C er værktøjet en fjederpåvirket rulle, som kan give efter et begrænset stykke, når den passerer den tand, der skal bukkes.The tools can be designed in different ways. Preferably, they are arranged so as to exert a gradually increasing pressure on the parts to be bent. For example, they can be shaped like scrolls or they can be shaped like cams of any desired profile. Since they are subject to wear, they should be made of the hardened material and placed so that they can be easily replaced. Some examples of tools are shown in FIG. 10. At A in this figure, the tool is a hardened piece of steel inserted into a slot 66 and secured with a screw 66. At B, the tool is a rotary cam or eccentric. At C, the tool is a spring-loaded roller that can yield after a limited stretch as it passes the tooth to be bent.

I fig. 3 er rillerne vist som enkeltgevind, men kan også være dobbelte.In FIG. 3, the grooves are shown as single thread but can also be double.

Maskinen ifølge opfindelsen har den fordel, at den let kan anbringes i fortsættelse af en zig-zagbukkemaskine specielt en sådan, med hvilken zig-zagstykkerne dannes med roterende organer, som f.eks. den i britisk patentskrift nr. 939 649 angivne maskine. Da maskinen i-følge opfindelsen drives med rotation, kan dens drivaksel kobles til zig-zagmaskinens aksel således, at de to maskiner drives synkront.The machine according to the invention has the advantage that it can easily be placed in continuation of a zig-zag bending machine, especially one with which the zig-zag pieces are formed with rotating means, such as e.g. the machine disclosed in British Patent No. 939,649. Since the machine according to the invention is driven by rotation, its drive shaft can be coupled to the shaft of the zig-zag machine so that the two machines are driven synchronously.

Når maskinen ifølge opfindelsen fortsætter en zig-zagmaskine, kan en vis længdeindstilling af valserne 28 og 30 være nødvendig for at forhindre stukning eller foldning af trådstykkerne. En sådan justering sker ved drejning af skrueskårne låseskiver 56 på valsernes drivaksler 58.When the machine according to the invention continues a zig-zag machine, a certain length adjustment of the rollers 28 and 30 may be necessary to prevent knitting or folding of the thread pieces. Such adjustment is made by turning screw-cut lock washers 56 on the drive shafts 58 of the rollers.
