Dupl. at 38 a: 8 2— • - As the base for the plates intended for cutting serves on the edge, a rust-like rib base fixed to transport chains is placed; However, it is also possible that the conveyor chains are not connected by ribs, but only elastic pads supported on angular links and in the area of cross-section saws are removed downwards from the conveyor plane, whereby suction slots can be arranged below the cutting paths for the cross-cut saws. If, jokingly, the transverse connection is separated by ribs, the conveyor chains are provided at least on the opposite sides with angular links, on which ribs are attached, which do not engage in the rollers of the chains. In such an embodiment, Darigenoth can also be removed from the transport plane by the entire rib base, so that in the area of the cross-sectional saws there is a free installation option for these, without the existing existing rib base being enlarged as a result of numerous saw cuts and feed. It is of course possible to distribute several such chains along the plate edge and possibly connect the adjacent chains through shorter rib sections, each at the rolling area for the chains & ports. At those at the edge. On the conveyor chains, the outwardly facing chain side can likewise be provided with angular links, on which an elastic cushion of the same thickness as the ribs is then arranged.

IVIaste man av flagon anledning avsta fran en nedfdring av transportoren i omradet for tvarskarningssagarna, sâ anvandes enligt en vidare uthildning av uppfinningen sasom transportor ett med kedjor drivet rostliknande ribbunderlag, vars ribbfordelning ar i relation till de for skarning avsedda plattlangderna sa avpassad, .att tvarsagningssnitten falla mellanrum, vilkas stillastaende under sagarna astadkomm_es darigenom, att den 1 kontakt med den inforda plattan kommande transportoren. i rorelse 'sattande omkopplaren ar sâ anordnad, att den trader i funktion, nar skarnhagsomeadet hos den inkommande plattan star Over ett mellanrum i ribbunderlaget. Ett stillastiende av ribbunderlaget for upptagning av en ny platta ar vid denna utforingsforra t. ex. till f8ljd av en 'gen.o.m kopplingsnockar pa transportkedjan upplyftbar .anordning en- dastnar ett mellanrum fdreligger pa lampligt avstand fran o.mkopplaren for transportforelsen. If, for the sake of flaking, a lowering of the conveyor in the area of the cross-cutting saws is avoided, according to a further embodiment of the invention a rust-like ribbed base driven by chains is used as the conveyor, the rib distribution of which is so adapted in relation to the plate lengths intended for cutting. fall intervals, the stillness of which during the saws is effected by the fact that the conveyor coming into contact with the inserted plate. The actuating switch is arranged so that it operates when the cutting edge of the incoming plate is above a space in the ribbed base. A standing position of the rib base for receiving a new plate is at this embodiment, e.g. due to a device which can be lifted through the coupling cams on the conveyor chain, only one space is located at an appropriate distance from the switch for the conveyor.

For att uppnâ en i mojligaste man likformig tillforsel av plattorna till formatsagen kan formatsagen enligt uppfinningen pa beskickningssidan lava drivna inmatningsvalsar, vacs rotationshastighet motsvarar den hastighet, med vilken transportoren framdrives. In order to achieve a as uniform as possible supply of the plates to the format saw, the format saw according to the invention can have driven feed rollers on the loading side, the rotational speed corresponding to the speed at which the conveyor is propelled.

For en automatisk likformig stapling av de fardigskurna plattorna foreslas enligt en ytter. ligare utforingsform 237 uppfinningen anordnandet av-utmatningsvalsar, till vilka I hojd med transportplanet ar anordnad en upplagg ningskonsol, vars bakre kant astadkommer en janan stapling av plattorna. Plattorna avlamnas pa ett hojdreglerbart sankbord. Plattorna bortforas efter staplingen exempelvis i stapel med en vagn eller en gaffeltruck och magnetis eras . For an automatic uniform stacking of the ready-cut plates is proposed according to an outer. more embodiment 237 of the invention provides dispensing rollers, to which at the height of the transport plane a support bracket is arranged, the rear edge of which provides a smooth stacking of the plates. The tiles are unloaded on a height-adjustable sink table. The plates are removed after stacking, for example in a stack with a trolley or a forklift and magnetis eras.

A bifogade ritning askadliggoras nagra utforingsexempel av uppfinningsforemalet. In the accompanying drawing, some embodiments of the object of the invention are illustrated.

Fig. 1 Visar ett tvarsnitt av formatsagen enligt uppfinningen, fig. 2 en planvy av densamma, fig. 3 en schematisk totalsidovy av en formatsag enligt uppfinningen med centreringsanordning, fig. 4 och 5 ett tvarsnitt och en schematisk sidovy av en annan utfdringsform och fig. 6 en sidovy .ay utmatningsvalsarna med efteranordnad upplaggningskonsol. Fig. 1 shows a cross section of the format saw according to the invention, Fig. 2 a plan view thereof, Fig. 3 a schematic overall side view of a format saw according to the invention with centering device, Figs. 4 and 5 a cross section and a schematic side view of another embodiment and Fig. 6 a side view of the discharge rollers with the rear mounting bracket.

Formatsagen enligt fig. 1 till 3. transporterar plattorna (25) pa ett i och f5r sig kant i langdskamingstiktningen rostliknande ribbunderlag (3), som bestar av ribbor, som are fastade pa vinkellankar (3) hos de transporterande kedjorna (1), som lampligen aro utbildade sasom rullkedjor. F8r att undvika en. forstdring av ribborna genom insagning av tvarskarningssagarna (20), are ribbavstanden och mellanrummen avpass•ade i relation till plattlangderna. Darigenom vinnes mojlighet till langdvariationer genom forskjutning av tvarskarningssagarna mom mellanrummen. .For att sakerstalla att det avsedda skarningsanaradet (25a) fdr plattorna aven alltid ligger ovanfor ett mellanrum hos ribbunderlaget, Or den framskjutningsrorelsen inkopplande elektriska omkopplaren (24) sa anordnad, att franaskjutningen stoppas, sa snort skarningszon_en (25a) befinner sig Over ett mellanrum hos ribbunderlaget. For att astadkomma en likfornaig tillforsel av plattorna, are enligt fig. 3 vid formatsagens beskiekningssida inmatningsvalsar anordnade, som rotera med samma hastighet som den, med vilken transport& ren framdrives. The format saw according to Figs. 1 to 3 transports the plates (25) on an in and of themselves edge in the longitudinal combing direction rust-like ribbed substrate (3), which consists of ribs which are attached to angular anchors (3) of the conveying chains (1), which aptly aro trained sasom roller chains. To avoid one. enlargement of the ribs by sawing in the cross-cutting saws (20), the rib spacing and the intervals being adjusted in relation to the plate lengths. In this way, the possibility of longitudinal variations is gained by shifting the cross-cutting saws between the intervals. In order to ensure that the intended cutting line (25a) in front of the plates is also always above a space of the rib base, the electrical switch (24a) engaging the projecting movement is arranged so that the cutting is stopped, so that the cutting zone (25a) is located above a space of the ribbed base. In order to achieve a uniform supply of the plates, according to Fig. 3, feed rollers are arranged at the mounting side of the format saw, which rotate at the same speed as the one with which the conveyor is propelled.

Fig. 3 visar en platta 25 i det lase, som den intager vid utforandet av tvankarningen. Plattan 25 har genom kontakt med omkopplaren -24a avbrutit framskjutningsrorelsen och samtidigt inkopplat centreringsanordningen. Genom kopplingsimpulsen ãr tryckanlaggningen 11 forsatt i drift, vilken till cylindrarna 6 Over ledningarna 7 tillfor tryckmediet, vilket forskjuter kolvarna 0, Isom Over ett havstangssystem (4, 4'). satta de centreringen astadkommande backama 10 i rorelse for centre-ring av plattan 25. Centreringsanordnin.gama pa ena sidan av plattan erhalla ett forsprang darigenom, att .antingen tvarsnittet hos led. ningarna 7 ar forstorat jamfort med det hos ledningarna pa den andra sidan, oiler aft kolvtvarsnittet Or mindre an vid kolvarna pa den andra sidan. For begransning av rorelsen hos de Oven en klamning astadkommande backarna 10 i centreringsanordningen Oro stallskru- — —3 var 9 anordnade, vilka tillata en rorelse hos backarna endast tills de uppnatt sina anslag. Bortkopplas efter fullbordad centrering trycket, sa astadkomma aterforingsfjadrarna 8 ett aterforande av backarna 10 'och 'stangsystemet 4, 4' till utgangslaget. Backama 10 uppvisa rundade .styrkanter. Fig. 3 shows a plate 25 in the laser which it occupies when performing the forced carriage. The plate 25 has, by contact with the switch -24a, interrupted the projecting movement and at the same time connected the centering device. Through the coupling impulse, the pressure system 11 is continued in operation, which supplies the pressure medium to the cylinders 6 over the lines 7, which displaces the pistons 0, Isom Over a sea rod system (4, 4 '). set the centering jaws 10 in motion for centering the plate 25. The centering devices on one side of the plate obtain a lead in that either the cross section of the joint. The connections 7 are enlarged in comparison with that of the lines on the other side, or the piston cross-section is smaller than at the pistons on the other side. In order to limit the movement of the jaws 10 forming a clamp in the centering device Oro stallskru- - —3 were 9 arranged, which allow a movement of the jaws only until they have reached their stops. After the centering is completed, the pressure is switched off, so that the return springs 8 provide a return of the jaws 10 'and the rod system 4, 4' to the starting layer. Backama 10 has rounded .guide edges.

Efter ,skedd centrering sattas tryckvalsarna 17 i drift, vilka rara sig nedat frail det streckat utvisade laget. Detta uppnas darigenom, att efter skedd centrering kranen 19 antingen over en tidsomkopplare eller en tryckomkopplare 18 i tryckledningen 7 till centreringscylindern vrides till det streckat visade lage, st att tryckmediet nu flyter over ledningen 12 till cylindern 13 och utovar ett tryck pa kolvarna 14, vilka Over ett stangsystem 16 med vinkelhavstanger 16a astadkomma anpressning av tryckrullarna 17 mot plattan 25. Hava tryckrullarna 17 uppnatt sitt understa lage, sa. sattas Over den darigenom manovrerade omkopplaren 24b tvarskarningssagarna i drift, vilka vid slutet av sin skarningsrorelse Over en icke visad omkopplare 16sgora centreringsanordningen och ater satta transportoren i rorelse, varpa det beskrivn.a forloppet upprepas. Den langdbeskurna plattan erhaller vid vidaretransport sidokantskarningarna genom langdskarningssagarna 21. I detta -skarningsomrade pressas plattan genom fjadrande tryckrullar 22 mot ribbunderlaget 3. After centering has taken place, the pressure rollers 17 are put into operation, which move downwards from the line expelled by the line. This is achieved in that after centering the tap 19 is turned over either a time switch or a pressure switch 18 in the pressure line 7 to the centering cylinder to the line shown, so that the pressure medium now flows over the line 12 to the cylinder 13 and exerts a pressure on the pistons 14, which Over a rod system 16 with angular sea rods 16a, the pressure rollers 17 are pressed against the plate 25. The pressure rollers 17 have reached their lowest layer, sa. The cross-cutting saws thus maneuvered by the switch 24b are put into operation, which at the end of their cutting movement switch the centering device 16 over a switch (not shown) and set the conveyor in motion again, whereupon the described process is repeated. During further transport, the long-cut plate obtains the side edge cuttings through the longitudinal cutting saws 21. In this cutting area, the plate is pressed by resilient pressure rollers 22 against the rib substrate 3.

I fig. 4 visas ett tvarsnitt genom en anordning, vars centreringsbackar manovreras genom havstanger 26, vilka arc lagrade vid kantzonen av en skiva t. ex. en excenter 27, vid vars vridning ett try& utovas pa backarna 10. Vid anpressad back 10 manovrerar havstangen 4 i detta exempel en omkopplare 18', som sitter tryckanlaggningen 11 i drift for manovrering av tryckrullarna 17. Ribbunderlaget be-star vid denna utforingsform av ribber 3', vilka endast arc fastade pa de hire vinkellankarna 2 hos transportkedjan 1, och icke ingripa I rullomradet. De yttre Vinkellankarna uppvisa elastiska kuddar 3" i hojd med ribborna 3'. De hire vinkellankarna kunna i stallet for ribbor 3' likaledes uppbara elastiska kuddar (streckat visat). Fig. 4 shows a cross section through a device, the centering jaws of which are maneuvered by sea rods 26, which arc are stored at the edge zone of a disc, e.g. an eccentric 27, in the rotation of which a pressure is applied to the jaws 10. In the case of a pressed jaw 10, the sea rod 4 in this example maneuvers a switch 18 ', which puts the pressure system 11 into operation for maneuvering the pressure rollers 17. The rib base in this embodiment consists of ribs 3 ', which only attached to the angular angles 2 of the conveyor chain 1, and did not engage the rolling area. The outer angle anchors have elastic cushions 3 "at the height of the ribs 3 '. The hire angle anchors can likewise support elastic cushions (dashed lines) instead of ribs 3'.

I fig. 5 visas schematiskt hur vid en format* ett ribbunderlag enligt fig. 4 med hjalp av exempelvis kugghjul bortfores nedat i omradet for tvarskarningssagarna 20. Darigenom undvikes belt skadegorelser pa ribbunderlaget och dessutom mojliggores anordnandet av insugningsslitsar 29a hos en. suganordning 29, genom vilken sagspanen bortfores frail omradet for tvarskarningen. Denna utforingsform ir fordelaktig, emedan bortsugningen av sagspanen hittills delvis berett avsevarda svarigheter, speciellt nar med tvarskarningssagarna en skaming utfores ,saval vid deras framatrorelse som vid deras tilbakagang. Fig. 5 schematically shows how in a format * a ribbed substrate according to Fig. 4 with the aid of, for example, gears is removed down in the area of the cross-cutting saws 20. This avoids belt damage to the ribbed substrate and also makes it possible to arrange suction slots 29a in one. suction device 29, through which the sawdust is removed from the area of the transverse cutting. This embodiment is advantageous, since the suction of the sawdust has hitherto partly prepared considerable responsibilities, especially when with the cross-cutting saws a shaming is performed, both at their advancement and at their decline.

Fig. 6 visar tva. pa avstand frau varandra stallbara utmatningsvalsar 23', .som -Oro Ms. - tade vid Auden av formatsagen. Bakom dessa Or upplaggningskonsolen ao anordnad, vars bakkant vid avlaggningen av plattorna 25 astadkommer en jamn stapling av plattorna. Avlaggningen av plattorna 25 sker lampligen pa ett hojdreglerbart sankbord, vars sinkhojd varje gang motsvarar tjockleken has plattorna. Vid denna anordning bortskjutes plattan, som har lamnat amradet f6r utmatningsvalsarna 23' och annu ligger pa upplaggningskonsolen, genom den efterfoljande plattan Over bakre kanten av upplaggningskonsolen 30. Fig. 6 shows two. spaced apart discharge rollers 23 ', .as -Oro Ms. - took at Auden of the format saw. Behind these, the support bracket is arranged, the rear edge of which, when the plates 25 are deposited, provides an even stacking of the plates. The deposition of the plates 25 takes place suitably on a height-adjustable sink table, the sink height of which each time corresponds to the thickness of the plates. In this device, the plate, which has left the frame for the discharge rollers 23 'and is still on the support bracket, is pushed away through the subsequent plate over the rear edge of the support bracket 30.
