DK 156952 BDK 156952 B

Den foreliggende opfindelse angâr en fremgangsmâde til deling af en glasplade og adskillelse af de pà denne mâde dannede dele, ved hvilken glaspladen fremfpres langs en transportbane, forsynes med mindst en brudanvisningslinie, der forlpber tilnærmelsesvis i 5 fremfdringsretningen og knækkes ved uddvelse af et bdjningsmoment omkring brudanvisningslinien, og de dannede dele bevæges bort fra hinanden ved pâtrykning af divergerende kræfter.The present invention relates to a method of dividing a glass plate and separating the parts formed in this way, in which the glass plate is advanced along a conveyor path, provided with at least one bridging line extending approximately in the direction of travel and broken by the application of a torque display around and the formed parts are moved apart by the application of divergent forces.

Fra beskrivelsen til britisk patent nr. 1.110.764 kendes en frem-10 gangsmâde til knækning af en glasplade, der er forsynet med en langs pladen forldbende brudanvisningslinie, og denne fremgangsmâde er ejendommelig ved, at der pâ glaspladens modstâende flader anbringes ensartet krummede bdjeorganer af komplementær form, hvilke bpjeor-ganer strækker si g tværs over pladen, og hvert omfatter et antal 15 berpringselementer til at bibringe pladen en krumning, som er tilstrækkelig til at knaekke pladen langs en vilkârlig brudanvisningslinie, som forlpber parallelt med krumningsaksen, men som er utilstrækkelig til at frembringe brud i noget brudanvisningsfrit pladeomrâde. Ved denne kendte fremgangsmâde fpres pladens knækkede 20 dele sædvanligvis med indbyrdes afstand langs en fælles transporter.From the specification of British Patent No. 1,110,764, a method of cracking a glass plate is provided which has a bridging guide line extending along the plate, and this method is characterized in that uniformly curved bending members of the glass plate are arranged on complementary form, which means extending across the plate, each comprising a plurality of 15 spring elements to impart a curvature sufficient to crack the plate along any breaking line line extending parallel to the axis of curvature but insufficient to produce fractures in any fracture-free plate area. In this known method, the fractured 20 parts of the plate are usually spaced apart along a common conveyor.

De separerede knækkede dele bliver derpâ stablet pâ palier.The separated broken parts are then stacked on pallets.

Hvad angâr den kendte teknik, skal der ogsâ henvises til beskrivelsen til USA patent nr. 3.491.634, hvorfra der kendes adskillelse af 25 glasplader ved anvendelse af en krum transporterai le, samt endvi-dere til beskrivelsen til USA patent nr. 2.504.655, hvorfra der kendes knækning af en bevæget glasplade ved pâtrykning af et bdj-ningsmoment omkring en brudanvisningslinie, der forlpber fra pladens forkant, som set i fremfpringsretningen, og til dens bagkant.With respect to the prior art, reference should also be made to the specification of U.S. Patent No. 3,491,634, from which separation of 25 glass sheets is known using a curved conveyor belt, and also to the specification of U.S. Patent No. 2,504,655. from which cracking of a moving glass plate is known by applying a torque around a bridging line extending from the leading edge of the plate, as seen in the projection direction, and to its rear edge.

If0lge den foreliggende opfindelse er fremgangsmàden kendetegnet ved, at de divergerende kræfter pâtrykkes ved i det mindste fladens forkant regnet i fremfdringsretningen, medens knækning tilvejebrin-ges ved at ldfte pladens bagkant op over dens forkant og ved at 35 pâtrykke bdjningsmomentet ved pladens bagkant.According to the present invention, the method is characterized in that the divergent forces are applied at least to the leading edge of the surface calculated in the direction of travel, while cracking is provided by lifting the rear edge of the plate over its leading edge and by applying the torque at the rear edge of the plate.

Den foreliggende opfindelse hviler pâ erkendelsen af, at det er vigtigt, at de divergerende kræfter uddves samtidig med, at knæk-ningen tilvejebringes. Ved at pâtrykke divergerende kræfter i 2The present invention rests on the recognition that it is important that the divergent forces are exerted at the same time as the cracking is provided. By applying divergent forces in 2

knækningsojeblikket pâtrykkes der en trækkraft pâ tværs af brudan-visningslinien, og knækning af glaspladen understpttes, og samtidig formindskes forskydnîngskræfter mellem de modstâende sider af de knækkede dele. I samme pjeblik knækning sker, forhindres hosværende 5 pladedele i at beskadige hinanden ved gensidig berpring. Endvidere bevirker tilvejebringelsen af knækningen ved Ipftning af pladens bagkant en forbedret kvalitet af brudet mellem pladedelene.moment of cracking, a traction force is applied across the bridging line, and cracking of the glass plate is supported, and at the same time shear forces are reduced between the opposing sides of the broken parts. At the same time cracking occurs, these 5 plate parts are prevented from damaging each other by mutual contact. Furthermore, providing the cracking by opening the back edge of the plate results in an improved quality of the break between the plate parts.

Opfindelsen angâr ogsâ et apparat til brug ved ud0velse af opfin-10 delsen, hvilket apparat har organer til fremfpring af glaspladen langs en transportbane, organer til tilvejebringelse af mindst én brudanvisningslinie» der forlpber tilnærmelsesvis i bevægelsesret-ningen, samt organer til knækning af pladen ved at pâtrykke denne et bpjningsmoment omkring brudanvisningslinien, samt organer til 15 . bevægelse af de dannede dele bort fra hinanden ved pâtrykning af divergerende kræfter. Ifplge opfindelsen er apparatet ejendommeligt ved, at det har en mekanisme til Ipftning af pladens bagkant op over dens forkant og til at pâtrykke bpjningsmomentet ved pladens bag-* kant, samt at transportbanen har transportorganer, der er indrettet 20 til at pâtrykke de divergerende kræfter langs fremfpringsretningen, og samtidig med at bpjningsmomentet pâtrykkes.The invention also relates to an apparatus for use in the practice of the invention, which apparatus has means for projecting the glass plate along a conveying path, means for providing at least one breaking guide line "which extends approximately in the direction of movement, and means for cracking the plate by to press this one a moment around the bridal guide line, as well as bodies for 15. movement of the formed parts apart by the application of divergent forces. According to the invention, the apparatus is characterized in that it has a mechanism for lifting the rear edge of the plate up over its leading edge and for applying the opening torque at the rear edge of the plate, and that the conveying path has transport means arranged to apply the divergent forces along the direction of projection and at the same time the opening torque is pressed.

Opfindelsen vil i det fplgende blive nærmere forklaret i forbindelse med en udfprelsesform, og under henvisning til tegningen, hvor 25 fig. 1 viser skematisk et fra oven set apparat, der udgpr en udfp-relsesform for den foreliggende opfindelse installeret i et transportant og forsynet med divergerende transportorer, 30 fig. 2 et snit gennem den forreste del af de divergerende transpor-tprer taget langs linien II-II i fig. 4, fig. 3 de divergerende transportprer set fra oven i stprre mâlestok, og 35 fig. 4 et sidebillede af en af transportprerne og en loftemekanisme.The invention will now be explained in more detail in connection with an embodiment, and with reference to the drawing, in which FIG. 1 is a diagrammatic view of an apparatus embodying an embodiment of the present invention installed in a conveyor and provided with divergent conveyors; FIG. 2 is a section through the front portion of the divergent conveyors taken along line II-II of FIG. 4, FIG. 3 is a plan view of the divergent transporters, and FIG. 4 is a side view of one of the conveyors and a ceiling mechanism.

De to midterste remtransportprer 10,12 er indbyrdes parai1 elle og parai-5 lelle med fremf0ringsretningen, medens de yderste remtransport0rer divergerer indbyrdes bort fra hinanden langs deres fremfpringsret-ning, hvor vinklerne mellem hosliggende transportprer er lige store.arranged a set of 4 divergent belt conveyor belts 11. The mutually divergent belt conveyor belts are formed as eight end-elastic resilient belts, e.g. V-belts, as shown in FIG. 2. The two middle belt conveyors 10,12 are parallel to each other and parallel to the conveying direction, while the outer belt conveyors diverge from one another along their conveying direction, where the angles between adjacent conveyors are equal.

Selvom der kun er vist otte elastisk eftergivelige remme i fig. 1, kan antallet af divergerende transportprer være st0rre eller mindre 10 i afhængighed af stprrelsen for de glasplader, som der skal knækkes.Although only eight elastically resilient belts are shown in FIG. 1, the number of divergent conveyors may be larger or smaller depending on the size of the glass sheets to be broken.

Under apparatets funktion fremfpres en med langsgâende brudanvis-ningslinie 3 forsynet glasplade 1 fra opstrpmstransportpren 2 til det divergerende transportprsæt 4. Glaspladen 1 detekteres derpà af 15 en detektor 9 og knækkes langs brudanvisningslinien pâ en i det fplgende nærmere forklaret mâde, og de to knækkede dele 7,8 dannes.During operation of the apparatus, a glass plate 1 provided with longitudinal bridging guide line 3 is raised from the upstream transport pin 2 to the divergent transport pin 4. The glass plate 1 is then detected by a detector 9 and broken along the bridge guide line in the following detailed explanation, and the two broken parts 7.8 is formed.

Fig. 2 viser et snit gennem opstrdmsdelene for to af de i fig. 1 viste endelpse kileremtransport0rer 10,12, hvor kileremmene 10,12 er anbragt pâ hver side af midterlinien for de divergerende trans-portprsæt 4. Pâ begge sider af hver kilerem er anbragt en kautsjuk-25 rulle 14, sâledes at et par ruller 14 knytter sig til hver kilerem. Kileremmene og deres tilhprende rullepar er lodret forskydeligt anbragte pâ respektive understptningstativer 20,22. Rulleparrene 14 og de opstrdms dele af kileremmene kan blive lpftet eller sænket med deres understptningsstativer pâ den i det fplgende i forbindelse med 30 fig. 3 og 4 beskrevne mâde.FIG. 2 is a section through the upstream portions of two of FIG. 1, the V-belt conveyor 10,12 shown, wherein the V-belts 10,12 are arranged on each side of the center line of the divergent conveyor sets 4. On each side of each V-belt is a rubber roller 14, so that a pair of rollers 14 intersect. say to every V-belt. The V-belts and their associated roller pairs are vertically slidably mounted on respective support racks 20, 22. The roller pairs 14 and the upstream portions of the V-belts can be lifted or lowered with their support racks on the following in connection with FIG. 3 and 4.

Ovenover kileremmene befinder sig et overliggende berpringsorgan bestâende af et sæt drevne eller frit drejeligt anbragte ruller 16, som er indstilleligt anbragt pâ bæreorganer 18 langs en buet eller 35 krum linie A-A.Above the wedge belts there is an overhead spring member consisting of a set of driven or freely pivotable rollers 16 which are adjustably arranged on support members 18 along a curved or curved line A-A.

Drivhjulet 24 roteres af en rem 28, som selv drives af en drivremskive 30 pâ en 5 drivaksel pâ en ikke-vist motor.4 on a support 15, as shown in FIG. 2 and 4. The drive wheel 24 and an end portion of the support 15 are secured to a support frame 32 pivotally mounted in a fixed bearing 34. The drive wheel 24 is rotated by a belt 28, which itself is driven by a drive pulley 30 on a 5 drive shaft of a drive shaft. engine not shown.

Det medlpbende hjul 26 og den anden endedel af understptningen 15 er fastgjort til den lodret forskydelige bæreramme 22.The auxiliary wheel 26 and the second end portion of the support 15 are attached to the vertically displaceable support frame 22.

10 Et nedadrettet fremspring pâ bærerammen 22 er pâ stedet 36 fastgjort til enden af en lodret stang 38, som er indrettet til at forskydes i et lodret anbragt styreorgan 40, som slutter tæt omkring stangen. Stangen 38 og styreorganet 40 tjener som en styreindretning til at holde remtransportpren 12 i et lodret plan, nâr enden af remtrans-15 portpren 12 hæves og sænkes.A downward projection of the support frame 22 is fixed in place 36 to the end of a vertical rod 38 which is arranged to be displaced in a vertically arranged guide member 40 which terminates tightly around the rod. The rod 38 and the control member 40 serve as a control means for holding the belt conveyor 12 in a vertical plane as the end of the belt conveyor 12 is raised and lowered.

Bærerammen 22 samvirker via en tryksko med en rulle 44. Rullen 44 er anbragt pâ en svingarm 46, som bæres pâ en tværgâende drejelig aksel 48, hvor svingarmens vægt er afbalanceret af en kontravægt 50. Et 20 nedadragende fremspring pâ svingarmen 46's endedel er forbundet med en Ipftecylinder 52. Oversiden af svingarmen 46 er forbundet med undersiden af bærerammen 22 via en fjeder 54, som trykker svingarmen bort fra bærerammen 22.The support frame 22 cooperates via a pressure shoe with a roller 44. The roller 44 is mounted on a pivot arm 46 which is carried on a transversely rotatable shaft 48, the weight of the pivot arm being balanced by a counterweight 50. A downwardly projecting projection on the end portion of the pivot arm 46 is connected to an upper cylinder 52. The upper surface of the swing arm 46 is connected to the underside of the support frame 22 via a spring 54 which pushes the swing arm away from the support frame 22.

25 Svingarme af forskellige længder er indrettet til at samvirke ved de forskellige indbyrdes divergerende remtransportprer til bibringelse af disse forskellige Ipftehpjder for en given bevægelse af den drejelige aksel 48. I fig. 4 er sâledes med stiplede linier vist en svingarm 56, som er mindre i yderdimensioner end svingarmen 46.25 Swing arms of various lengths are arranged to cooperate with the various mutually divergent belt conveyors to provide these different lifting heights for a given movement of the rotatable shaft 48. In FIG. 4, a pivotal arm 56, which is smaller in outer dimensions than the pivotal arm 46, is thus shown in broken lines.

30 Svingarmen 56 samvirker med en anden remtransportpr, f.eks. med remtransportpren 11 i fig. 1, og pâ analog mâde, som det er tilfæl-det for svingarmen 46.The swing arm 56 cooperates with another belt conveyor, e.g. with the belt conveyor 11 in FIG. 1, and by analogy as is the case for the swing arm 46.

Under apparatets funktion fremfpres en glasplade med mindst én i sin 35 længderetning forlpbende brudanvisningslinie 3 i den i fig. 1, 3 og 4 viste retning B over de indbyrdes divergerende transportprer, indtil pladens bagkant skal fpres mellem de i fig. 4 viste ruller 16 og 14. Bagkanten detekteres af den i fig. 1 viste detektor 9, som afgiver et signal til aktivering af et ikke-vist hydraulisk eller 5During operation of the apparatus, a glass plate with at least one bridging guide line 3 extending in its longitudinal direction in the embodiment of FIG. 1, 3 and 4 over the divergent conveyor sheaves, until the trailing edge of the plate must be pressed between those in FIG. 4, rollers 16 and 14. The trailing edge is detected by the embodiment shown in FIG. 1, which emits a signal for actuating a non-shown hydraulic or 5

pneumatisk anlæg, der er operativt forbundet med trykmediumscylin-deren 52. Stemplet i cylinderen 52 trykkes opad og bevirker en drejning med uret af svingarmen 46. Drejningen af svingarmen 46 bevirker drejning af den drejelige aksel 48, som igen bevirker 5 samtidig drejning med uret af aile de i indbyrdes afstand pâ den drejelige aksel 48 langs denne fastgjorte svingarme. Rullerne 44, som er anbragt pà oversiden af hver svingarm, ligger opadtil an mod den tilhprende bæreramme sâsom 22, der er fastgjort til den respek-tive remtransportpr 10,11,12's opstrpms værende del. Pà denne mâde 10 Ipftes hver remtransportprs opstrpmsdel i forhold til transportons bageste ende, der drejer omkring lejet 34. Hver transporter holdes i sit lodrette plan under Ipftebevægelsen ved hjælp af respektive styreindretninger bestàende af en stang 38 og et styreorgan 40, og den hpjde til hvilken hver remtransportpr Ipftes afhænger af den 15 respektive svingarms dimensioner og vinkel under hvilken den er anbragt pâ den drejelige aksel. Hpjden er forudindstillet til at bringe den pverste si de af glaspladens bagkant i indgreb med rullerne 16. Hvert par ruller 14, der er anbragt pâ dertil hprende understptningsstativ og bæreramme 20,22, Ipftes det samme stykke som 20 den pâgældende transportas opstrpmsende. Pâ denne mâde drejes de divergerende transportons opstrpmsdele opad, og transportprernes ender danner en pâ tværs af fremfpringsretningen forlpbende krum-ning, der er komplementær til krumningen for rullesættet 16. Ved at bibringe glaspladens bagkant denne krumning, medens den fores frem 25 over de divergerende transportprer mellem rullerne 16 og rullerne 14, dannes et bpjningsmoment om brudanvisningslinien 3. Bpjningsmo-mentets stprrelse afhænger af den krumning, pladen bibringes, hvilken krumning er indstillet sâledes, at pladen knækkkes langs brudlinien, men ikke i noget brudanvisningsfrit omràde af pladen.pneumatic system operatively connected to the pressure medium cylinder 52. The piston of the cylinder 52 is pressed upwards and causes a clockwise rotation of the pivot arm 46. The rotation of the pivot arm 46 causes rotation of the pivot shaft 48 which in turn causes 5 pivotal clockwise rotation. align spaced apart on rotatable shaft 48 along this pivoted swingarm. The rollers 44 disposed on the upper side of each pivot arm abut the abutment supporting frame 22 such as is attached to the upstream portion of the respective belt conveyor 10,11,12. In this way, the upstream portion of each belt conveyor is lifted relative to the rear end of the conveyor which rotates about the bearing 34. Each conveyor is held in its vertical plane during the lifting movement by respective control means consisting of a rod 38 and a guide member 40, and the height to which each belt conveyance depends on the dimensions and angle of the respective swing arm under which it is mounted on the pivot shaft. The guide is preset to engage the uppermost of the glass edge of the glass plate with the rollers 16. Each pair of rollers 14 disposed on the supporting support frame and support frame 20, 22 is lifted the same piece as the upstream end of the conveyor in question. In this way, the upstream portions of the divergent conveyor are pivoted upward and the ends of the conveyors form a curvature extending transversely of the projection which is complementary to the curvature of the roller set 16. By imparting this curvature to the rear edge of the glass plate, it is advanced over the divergent conveyor. between the rollers 16 and the rollers 14, an opening moment is formed about the bridging line 3. The size of the opening moment depends on the curvature imparted to the plate, which curvature is adjusted such that the plate is broken along the breaking line, but not in any bridle-free area of the plate.

30 Efter at pladen er blevet knækket langs brudanvisningslinien, sænker trykmediumcylinderen 52 de indbyrdes divergerende transportprer. Som en sikkerhedsindretning trykker hver fjeder 54 fprst svingarmen bort fra bærerammen 22, og sættes derpâ under spænding for derved at medvirke ved tilbagetrækning af svingarmen, og sænkning af rem-35 transportprerne fpr den næste glasplade ankommer til apparatet.After the plate has been broken along the bridging line, the pressure medium cylinder 52 lowers the mutually divergent transport shreds. As a safety device, each spring 54 first pushes the pivot arm away from the support frame 22, and is then put under tension to thereby assist in retracting the pivot arm, and lowering the belt conveyors before the next glass plate arrives at the apparatus.

Der kan ogsâ anvendes andre organer end en trykmediumcylinder til Ipftning af de divergerende remtransportprer. F.eks. kan der langs den drejelige aksel være anbragt et antal excentriske kamskiver 6Means other than a pressure medium cylinder may also be used to open the divergent belt conveyors. Eg. For example, a plurality of eccentric cam washers may be arranged along the rotatable shaft 6

DK 156952 BDK 156952 B

eller krumtappe, hvor hver kamskive eller krumtap samvirker med en tilhprende remtransportpr til l0ftning og sænkning af denne.or cranks, where each cam washer or crank cooperates with an associated belt conveyor for lifting and lowering it.

Divergeringsvinklen i et vandret plan mellem hver af de divergerende 5 remtransporterer og fremf0ringsretningen B bestemmer, hvor meget de knækkede glaspladedele fjernes fra hinanden. I fig. 3 er det mid-terste transportprpar 10,12 indbyrdes parallelle, men pâ hver side af dette par vokser divergeringsvinklerne mellem ved siden af hinanden anbragte transport0rer trinvis en halv grad. Divergerings-10 vinklen mellem ved siden af hinanden anbragte transportprer kan imidlertid indstilles til at ændres med vinkler, som er mindre end eller stprre end en halv grad.The divergence angle in a horizontal plane between each of the divergent belt conveyors and the feed direction B determines how much the broken glass plate parts are removed from each other. In FIG. 3, the middle transport pair 10,12 is parallel to each other, but on each side of this pair the divergence angles between adjacent transporters grow incrementally by half. However, the angle of divergence between adjacent transverse conveyors can be set to change at angles less than or greater than half a degree.

I et typisk anlæg anvendes toogtyve indbyrdes divergerende rem-15 transportprer med elleve transportprer pâ hver side af midterlinien og med divergeringsvinkler pâ en halv grad mellem hvert par ved siden af hinanden anbragte transportprer. Rullesættet 16 indstilles med en fast krumningsradius pà 13,1 m, og svingarmene har forskel-lige radier, sâledes at enderne af de divergerende transportprer, 20 nâr disse er lpftet, er beliggende pâ en kurve med en krumningsradius pà 13,1 m.In a typical plant, twenty-two mutually divergent belt conveyors are used with eleven conveyors on each side of the center line and with divergence angles at half a degree between each pair of adjacent conveyors. The roller set 16 is set with a fixed radius of curvature of 13.1 m, and the swing arms have different radii so that the ends of the divergent transport springs, 20 when lifted, are located on a curve with a radius of curvature of 13.1 m.

» En fordel ved de divergerende transportprer er, at der afgives modsat rettede kræfter pâ hver pladedel i knækningspjeblikket. De 25 modsat rettede kræfter afgiver en trækkraft pâ tværs af brudanvis-ningslinien i glaspladens plan og separerer de knækkede dele, sâ snart som disse dannes. Det er pâ grund heraf, at remmene er anbragt i noter eller kanaler. Disse tværgâende kræfter medvirker ved knækntngen af glaspladen, og forskydningskræfter mellem de mod 30 hinanden vendende flader for de knækkede dele formindskes. De op ad hinanden liggende glasplader hindres ligeledes i at beskadige hinanden ved indbyrdes berpring. *»An advantage of the divergent transport bar is that opposite directed forces are released at each plate part at the moment of cracking. The 25 oppositely directed forces exert a transverse traction across the bridging line in the plane of the glass plate and separate the broken parts as soon as they are formed. It is for this reason that the straps are placed in notes or channels. These transverse forces contribute to the cracking of the glass plate and shear forces between the facing surfaces of the broken parts are reduced. The adjacent glass panels are also prevented from damaging each other by mutual contact. *

En yderligere fordel er, at de knækkede glaspl adedele kan fpres til 35 npjagtigt definerede positioner pâ den nedenstrpms anbragte trans-portpr 6 i korrekt vinkelret forhold dertil, d.v.s. med deres kanter parallelle med- og deres forkanter og bagkanter vinkelret pâ trans-portanlæggets midterlinie, medens et kendt anlæg, der anvender skràtstillede ruller til at separere de knækkede dele af glaspladen, 7A further advantage is that the broken glass panels can be pressed to 35 precisely defined positions on the downstream transport port 6 in proper perpendicular relation thereto, i.e. with their edges parallel to their and their leading edges and trailing edges perpendicular to the center line of the conveyor system, while a known system utilizing inclined rollers to separate the broken parts of the glass plate 7

var tilbpjeligt til at foretage en uforudsigelig positionering af de knækkede dele. Desuden kan cyklustiden mellem hver glasplade, der f0res langs transport!inien, reduceres til en lav værdi, f.eks. ca. et sekund pâ grund af at kun den ene ende af apparatet aktiveres.was inclined to make an unpredictable positioning of the broken parts. In addition, the cycle time between each glass plate carried along the transport can be reduced to a low value, e.g. ca. one second because only one end of the device is activated.

Selvom der i det foregâende er forklaret, at der til knækning af glaspladen bibringes denne en ensartet tværkrumning, mà det forstâs, at opfindelsen ogsà kan uddves med uensartet forlpbende krumning.Although it has been explained in the foregoing that for cracking of the glass plate it is imparted a uniform cross-curvature, it should be understood that the invention can also be practiced with non-uniform curvature.

10 Det vil desuden forstâs, at selvom den viste og forklarede udfprel-sesform for apparatet anvendes til at knække en plade med en enkelt langsgâende forlpbende brudanvisningslinie, kan apparatet ogsâ anvendes til knækning af plader med flere langsgâende brudanvis-ningslinier, f.eks. med to brudanvisningslinier til dannelse af tre 15 knækkede dele eller tre brudanvisningslinier til dannelse af fire knækkede dele.It will further be appreciated that, although the shown and explained embodiment of the apparatus is used to crack a plate with a single longitudinal extending bridging line, the apparatus may also be used to crack plates with multiple longitudinal bridging lines, e.g. with two bridle guide lines to form three broken parts or three bridle lines to form four broken parts.

Det vil forstâs, at det er fordelagtigt, at drive transportpren 12's nedenstrpmshjul 24, som forklaret i det foregâende i stedet for det 20 ovenstrpms anbragte hjul 26, eftersom dette forenkler konstruktionen ved at overfl0digg0re behovet for drivorganer i omrâdet for trans-portprens opstrpmsende, hvor Ipftemekanismen er beliggende. Det vil endvidere forstâs, at hjulet 24 i stedet for at blive drevet af drivrem 28, som vist og forklaret, om pnsket kan blive drevet af 25 selve transportprremmen 12, hvis denne rem 12 forlænges og indrettes til at Ipbe fra hjul et 24 omkring drivremskiven 30 og derpâ via et passende strammeorgan, der er anbragt et sted langs remmens returlpb til opstrpmshjulet 26.It will be appreciated that it is advantageous to drive the downstream wheel 24 of the transport spring 12, as explained above, rather than the wheel 26 disposed above, since this simplifies the construction by overstating the need for drive means in the area of the upstream end of the transport spring, The Iftft mechanism is located. It will further be understood that instead of being driven by drive belt 28 as shown and explained, the wheel 24 may be driven by the conveyor belt 12 itself if this belt 12 is extended and arranged to eject from a wheel 24 around the drive pulley 30 and then via a suitable tensioning means disposed at a position along the return lap of the belt to the upstream wheel 26.
