Description

1 Foreliggande uppfinning hanfor sig till transportorer, och speciellt, men icke uteslutande till en projektiltransportor for ett magasin till eldvapen. 1 The present invention relates to conveyors, and in particular, but not exclusively, to a projectile conveyor for a magazine for firearms.

Transportorer är kanda, dar cylindriska faremal transporteras genom att rullas langs en stational- ledbana, varvid vart och ett av foremdlen framfores i transportriktningen medelst en pdskjutningsanordning, som stracker sig tvdrs transportriktningen. Ledbanan innefattar vanligen en botten med ledarvaggar pd vardera sidan, sä att foremdlen hindras att rOra sig i tvarriktningen och frdn att rulla av banan. Conveyors are known in which cylindrical hazards are transported by rolling along a stationary conveyor, each of the preforms being conveyed in the conveying direction by means of a pushing device which extends transversely to the conveying direction. The guideway usually comprises a bottom with guide cradles on each side, so that the preforms are prevented from moving in the transverse direction and frdn to roll off the track.

Olagenheter hos sadana transportorer utgores av att de endast är lampade for foremdl av en bestamd langd, vilken definieras av avstdndet mellan ledarvaggarna, och att i vissa fall forekomsten av en ledarvdgg icke kan godtagas, exempelvis i en pro- jektiltransportor till ett eldvapensmagasin, dar det foremdl som transporteras utgOr en projektil, vilken har en cylindrisk kropp, som vid ena dnden avslutas av en plan andyta och vid den andra dnden har ogival form, innefattande ett tandror. Medan i detta exempel dndytan fdr komma i kontakt med en ledarvagg, sd är varje andkontakt med den ogivala dnden oonskad pd grund av risken for att tandroret stores. En ytterligare olagenhet has ledarvaggarna är att de begransar Atkomligheten av foremdlen. Denna dtkomlighet kan vara nedvandig, exempelvis om en projektil fastnar i en projektiltransportor. Disadvantages of such conveyors are that they are only illuminated for example of a certain length, which is defined by the distance between the conductor cradles, and that in some cases the presence of a conductor wall cannot be accepted, for example in a jektiltransportor to a firearms magazine, where it foremdl as transported is a projectile which has a cylindrical body which at one end is terminated by a flat surface and at the other end has an unequal shape, comprising a toothed tube. While in this example the surface of the duct before coming into contact with a conductor cradle, then any duct contact with the involuntary duct is undesirable due to the risk of that the toothpick stores. An additional disorder is the leader cradles is that they limit the Accessibility of the precedent. This accessibility can be trivial, for example if a projectile gets stuck in a projectile conveyor.

En ledbana med en enda ledarvagg har den olagenheten att foremal kan rulla av banan eller forflyttas i tvdrriktningen vid vibrationer eller om banan lutas. A joint path with a single conductor cradle has the disadvantage that foremal can roll off the track or be moved in the opposite direction at vibrations or if the track is tilted.

Pet utgor ett syftemal hos foreliggande uppfinning att tillhandahdlla en transportor, som har framfbringsanordningar, varigenom ett cylindriskt foremdl som framfores i en transportriktning genom rullning kan foras i en tvarriktning mot en enda ledarvdgg, under det att andkontakt mellan foremdlet och framforingsanordningen undvikes. It is an object of the present invention to provide a conveyor having conveying devices, whereby a cylindrical object is conveyed in a conveying direction by rolling can be guided in a transverse direction towards a single conductor edge, while avoiding duct contact between the front part and the feed device.

Enligt foreliggande uppfinning innefattar en transportor for ett relativt rullande foremdl en framforingsmatta for att genom friktion gripa och.fora foremdlet i en framfOringsriktning tvdrs rullningsriktningen, varvid mattan har minst en elastisk stodribba, som dr sammanpressbar till rullande kontakt med foremdlet, som stracker sig vdsentligen parallellt med rullningsriktningen, och sem utsticker fran mattan i en riktning, som under spetsig vinkel 4C(hdr benamnd utstickningsvinkeln) lutar mot framforingsriktningeJ. 2 Vid anvdndning kommer en sammantryckning av mattan genom det relativt denna rullande foremdlet att Atfoljas av en deformation I tvdrriktningen av stbdribban, vilken genom friktion griper foremdlet och for det i tvdrriktningen. Ldmpligen är mattan anordnad under foremdlet, sd att den dã sammanpressas under foremdlets tyngd. According to the present invention, a conveyor for a relatively rolling front part comprises a feed mat for passing through friction grip and.fora foremdlet in a forward direction tvdrs the rolling direction, the mat having at least one elastic standing rib, which is compressible into rolling contact with the preform, which extends substantially parallel to the rolling direction, and which projects from the mat in a direction which, at an acute angle, 4C (hdr called the protrusion angle) is inclined to the direction of advanceJ. 2 In use, a compression of the mat by the rolling object relative to it will be accompanied by a deformation in the transverse direction of the support rib, which by friction grips the preform and moves it in the opposite direction. Typically, the mat is arranged under the preform, so that it is then compressed under the weight of the preform.

Transportoren innefattar foretrddesvis en ledarvdgg som strdcker sig parallellt med transportriktningen och intill mattan, varvid lutningen av stodribban mot ledarvdggen är sddan, att det relativt rullande foremdlet fbres till att med sin dnde komma i kontakt med ledarvdggen. The conveyor preferably comprises a guide wall which extends parallel to the conveying direction and adjacent to the mat, the inclination of the standing bar towards the guide wall being such that it relatively rolling prey is forced to come in with its breath contact with the leader.

Mattan kan ldmpligen vara forsedd med ett flertal stodribbor fdstade vid en gemensam underlagsdel med en plan basyta, varvid stodribborna och underlagsdelen ldmpligen kan vara utfOrda i ett stycke av ett syntetiskt gummimaterial. The mat may, for example, be provided with a plurality of standing ribs fixed to a common base part with a flat base surface, wherein the standing bars and the base part may simply be made in a piece of a synthetic rubber material.

Varje stOdribba kan ldmpligen ha en stbdyta parallell med basytan, en plan fOrsta sidoyta som lutar mot basytan med en spetsig utstickningsvinkel, och en med indtriktad hdlkdl forsedd andra sidoyta, vilken skdr stOdytan sá, att en gripande kant bil- das. Each support rib may, for example, have a support surface parallel to the base surface, a flat first side surface which is inclined towards the base surface with an acute protrusion angle, and a second side surface provided with a retracted tow bar, which cuts the support surface so that a gripping edge das.

En utforingsform av uppfinningen kommer hdr att beskrivas som enbart ett exempel, under hdnvisning till den medfoljande ritningen. An embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings.

I ritningen visar fig. 1 en perspektivvy av en dnddel av en matta, ldmplig for anvdndning i en transportor. Fig. 2 utgor en sektionsvy av mattan i fig. 1 under en sammanpressande belastning med ett cylindriskt fbremAl. Fig. 3 visar ett cylindriskt foremdl som rullar pd samma matta. In the drawing, Fig. 1 shows a perspective view of a part of a mat, suitable for use in a conveyor. Fig. 2 is a sectional view of the mat of Fig. 1 under a compressive load with a cylindrical frame. Fig. 3 shows a cylindrical preform rolling on the same mat.

Fig. 4 utgor en dndvy av en projektiltransportor for ett ma- gasin till eldvapcn, och innefattar samma matta sedd i rullnings- riktningen. Fig. 5 utgor en sidovy av projektiltransportoren i fig. 4, och fig. 6 utgOr en perspektivvy av den i fig. 1 visade mattan, anordnad for transport av ett icke-cylindriskt foremAl. Fig. 4 is a view of a projectile conveyor for a machine gas to the firearm, and includes the same mat seen in the rolling the direction. Fig. 5 is a side view of the projectile conveyor of Fig. 4, and Fig. 6 is a perspective view of the mat shown in Fig. 1, arranged for transporting a non-cylindrical object.

Fig. 1 visar en matta 1 i enlighet med foreliggande upp- finning, med en plan underlagsdel 2 med en basyta 3, och forsedd med sex stodribbor 4, vardera med en stodyta S. Varje stedribba 4 har en plan sidoyta 6, vilken med en spetsig utstickningsvinkel A lutar mot basytan 3, och en med hdlkdl fOrsedd yta 7, som skdr stodytan S vid en gripkant 8. Mattan dr utferd av ett syntetiskt 4Cgummimaterial som är elastiskt deformerbart och som ger stbdytan 3 en hog friktionskoefficient. Fig. 1 shows a mat 1 in accordance with the present invention. finning, with a flat base part 2 with a base surface 3, and provided with six support bars 4, each with a support surface S. Each place bar 4 has a flat side surface 6, which with a pointed protrusion angle A slopes towards the base surface 3, and one with hdlkdl provided surface 7, which cuts the support surface S at a gripping edge 8. The mat dr excursion of a synthetic 4C rubber material which is elastically deformable and which gives the support surface 3 a high coefficient of friction.

Fig.2 visar mattan 1 enligt fig. 1 liggande pd ett stelt underlag 9 och uppbarande ett cylindriskt foremdl 10, vilket har en cylindrisk yta 11, som rullar i en riktning parallel' med stod- ribborna 4, varvid perspektivvyn är vertikalt sektionerad genom cylinderaxeln for foremdlet 10 for att visa deformationen hos stedribborna 4 vid sammantryckning mellan underlaget 9 och foremalet 10. Deformationen av stodribborna 4 sker successivt alit eftersom fOremalet rullar framdt, varvid belastningen pa stodytan 5 succe- sivt Okar och balanseras av en reaktion frdn den deformerade stOd- ribban 4, vilken undergdr skjuvning i tvdrriktningen, angiven av pilen X. Skjuvrorelsen, varigenom sidoytan 6 blir mera spetsigt lutande mot basytan 3, atfoljes av en forskjutning av stodytan i tvdrriktningen X, vilket medfor att en friktionskraft i tvdrrikt- ningen utovas pa foremalet 10. Fig. 2 shows the mat 1 according to Fig. 1 lying on a rigid base 9 and supporting a cylindrical preform 10, which has a cylindrical surface 11, which rolls in a direction parallel 'to the stand. the ribs 4, the perspective view being vertically sectioned through the cylindrical axis of the front part 10 to show the deformation of the seat ribs 4 upon compression between the base 9 and the front mold 10. The deformation of the side ribs 4 takes place successively as the front wheel rolls forward, the load on the side surface 5 succeeding. Increases and is balanced by a reaction from the deformed rib 4, which undergoes shear in the transverse direction, indicated by the arrow X. The shear movement, whereby the side surface 6 becomes more pointedly inclined towards the base surface 3, is accompanied by a displacement of the support surface in the opposite direction X, which causes a frictional force in the opposite direction. ningen utovas pa foremalet 10.

Fig. 3 visar schematiskt ett cylindriskt foremal 10 med en cylindrisk yta 11, som rullar pa mattan 1 i en framdtriktning, som visas av pilen Y. En framre del 13 av cylinderytan 11 som ligger framfor foremdlets cylinderaxel 15 är i kontakt med bdr- ytan 5 has mattan 12, och utsdttes for en friktionskraft i tvdr- riktningen, visad av pilen X, ndr stodribborna 4 undergdr en successiv kompression och skjuvning under tyngden av det trans- porterade feremalet 10, Den bakre del 14 av ytan 11, som ligger bakom cylinderaxeln 13 utsdttes for en friktionskraft i motsatt riktning ndr stod- ribborna 4 dtergdr till sin ursprungliga form under det successiva avldgsnandet av foremalets tyngd, men denna motverkandekraft är pa grund av stodmaterialets hysteres mindre an den som utovas pd den frdmre delen, sa att det foreligger en framforande netto- 3Ckraft, som verkar i tvdrriktningen X. Dessutom verkar gripkanten 8 pa varje stodribba sá, att friktionen mellan den cylindriska ytan 11 och stodytan 5 okas vid sammantryckningen av stodribborna 4, och bidrager ddrigenom till den framfOrande nettokraften. Fig. 3 schematically shows a cylindrical object 10 with a cylindrical surface 11, which rolls on the mat 1 in a forward direction, shown by the arrow Y. A front part 13 of the cylinder surface 11 which lies in front of the cylinder axis 15 of the object is in contact with the surface 5 has the mat 12, and is subjected to a frictional force in the the direction, shown by the arrow X, when the standing ribs 4 undergo a successive compression and shear under the weight of the The rear part 14 of the surface 11, which lies behind the cylinder shaft 13 is exposed to a frictional force in the opposite direction when standing the ribs 4 return to their original shape during the successive removal of the weight of the object, but this counteracting force is due to the hysteresis of the support material less than that exerted on the front part, so that there is a advancing net. 3Craft, which acts in the opposite direction X. In addition, the gripping edge acts 8 on each support rib so that the friction between the cylindrical surface 11 and the support surface 5 is increased by the compression of the support ribs 4, thereby contributing to the advancing net force.

Framforingskraften verkar i samma riktning for rullning av foremalet sdvd1 framdt som bakat, dvs kraften verkar alltid i den tvdrriktning X,. som definieras av lutningen has stodribborna 4. Vid franvaro av dterhdllande krafter pa foremdlet 10 kommer ddrfor en rullning av foremalet i endera riktningen parallellt med stodribborna 4 att innebdra en forflyttningsrtirelse, varige- nom det rullande foremdlet forflyttas axiellt utan att dndra riktning. The feed force acts in the same direction for rolling off foremalet sdvd1 presented as baked, ie the power always works in the two-way direction X ,. which is defined by the inclination has the standing ribs 4. In the absence of restraining forces on the front member 10, therefore, a rolling of the object in either direction parallel to the standing ribs 4 will involve a displacement movement, lasting by the rolling object is moved axially without changing direction.

En projektiltransportor for anvdndning i ett magasin fOr eldvapen och innefattande mattan 1 enligt fig. 3 kommer i det foljande att beskrivas under hdnvisning till fig. 4. En projektil- Stransportor 20 innefattar en ledbana 21 med en ledarvdgg 22 som strdcker sig uppAt frAn och lAngs med en stel underlagsdel 23, som har en Ovre yta 25. Mattan 1 ligger i en urtagning 24 i underlagsdelen 23 och har sex stodribbor 4, som sticker ut ovanfor den byre ytan 25 och strdcker sig parallellt med ledarvaggen 22. A projectile conveyor for use in a firearms magazine and including the mat 1 of Fig. 3 will be described in the following with reference to Fig. 4. Conveyors 20 comprise a guideway 21 with a guideway 22 which extends upwards from and along with a rigid base part 23, which has an upper surface 25. The mat 1 lies in a recess 24 in the base part 23 and has six standing ribs 4, which protrude above the upper surface 25 and extend parallel to the conductor cradle 22. .

StOdribborna 4 lutar mot ledarvaggen 22 med en spetsig vinkel mot den tvdrriktning som dskddliggores av pilen X, vilken är vinkelrdt mot ledarvdggen 22. The pillar ribs 4 are inclined towards the guide cradle 22 at an acute angle to the transverse direction deflected by the arrow X, which is perpendicular to the guidewire 22.

En projektil 26 som ligger pd ledbanan 21 har en cylindrisk yta 27 med en cylinderaxel 28, en plan dnde 29 som ligger mot ledarvdggen 22, och en ogival dnde 30, som innefattar ett tändrör 31. Transportoren 20 innefattar fjdderbelastade kldmmor 32 och 33 som pressar projektilen 26 neddt mot underlagsdelen 23 och som tillsammans med projektilens tyngd verkar till att deformera den del av mattan 1 som är beldgen under projektilen, sd att stod- ribborna 4 tvingas till sdvd1 kompression som skjuvning. Trans- portoren 20 innefattar dven en pAskjutningsdel 34 med skyddsrullar 35, vilken är glidbar i ett glidhus 36 i en riktning parallell med ledbanan 21, varigenom projektilen 26 kan fds till att rulla ldngs ledbanan. A projectile 26 lying on the articulation 21 has a cylindrical surface 27 with a cylinder axis 28, a flat end 29 lying against the conductor wall 22, and an inequal end 30, which includes one spark plugs 31. The conveyor 20 comprises spring-loaded clamps 32 and 33 which press the projectile 26 down against the base part 23 and which together with the weight of the projectile act to deform the part of the mat 1 which is bellows under the projectile, so as to stand. the ribs 4 are forced to sdvd1 compression as shear. Trans- the port 20 also includes a launch member 34 with protective rollers 35, which is slidable in a slide housing 36 in a direction parallel to the guideway 21, whereby the projectile 26 can be caused to roll along the guideway.

Fig. 5 visar projektiltransportoren 20 i fig 4 och innehdl- lande tre projektiler 26, 37 och 38. Vid drift av transportoren bringas projektilerna av pAskjutningsanordningarna 34a, 34b och 34c att rulla ldngs ledbanan 21 och mattan 1 i den riktning, som visas av pilen Y. Kompressionen och skjuvningen av stedribborna i mattan 1 under vane projektil Astadkommer en forskjutnings- kraft, som pressar projektilerna mot ledarvdggen 22, och denna kraft sakerstaller att andarna 29 glider utefter ledarvaggen 22, sá som visas i fig. 4, och bidrager till att sdkerstdlla att varje cylinderaxel 28 forblir vinkelrdt mot transportriktningen Y. Verkan av mattan 1 motverkar sdlunda vane bendgenhet has projektilen pd transportoren 20 att genom vibrationer eller lut- ning av transportoren forflyttas bort frAn ledarvdggen 22. Eftersom endast en ledarvdgg 22 erfordras, kan projektiltransportoren 20 anvdndas for att transportera projektiler med 4Colika ldngd, forutsatt att de delar av projektilen som är i kon- takt med stbdribborna har vasentligen samma diameter, och har fordelen av att den ogivala dnden 30 av en projektil 26 är lattAtkomlig, sa att ddrigenom underldttas installning och byte av tandraret 31. Vid mekaniska fel has transportbren kan projektiler aven ldtt avldgsnas genom att de fjdderbelastade klammorna 32, 33 lyftes for att frigora projektilen. Fig. 5 shows the projectile conveyor 20 in Fig. 4 and containing three projectiles 26, 37 and 38. During operation of the conveyor, the projectiles are caused by the launchers 34a, 34b and 34c to roll along the guideway 21 and the mat 1 in the direction shown by the arrow Y. The compression and displacement of the locomotives in carpet 1 under the habit of projectile Achieves a displacement force, which presses the projectiles against the guide wall 22, and this force ensures that the spirits 29 slide along the guide wall 22, as shown in Fig. 4, and helps to ensure that each cylinder axis 28 remains perpendicular to the direction of transport. Y. The effect of the carpet 1 counteracts the habit of bending the projectile on the conveyor 20 that by vibration or inclination moving the conveyor away from the guide wall 22. Since only one guide wall 22 is required, the projectile conveyor 20 can be used to transport projectiles with 4Colica ldngd, provided that the parts of the projectile that are in stroke with the struts is essentially the same diameter, and has the advantage that the unobstructed end 30 of a projectile 26 is easily accessible, so that it facilitates installation and replacement of the toothed rack 31. 32, 33 are lifted to release the projectile.

Mattor i enlighet med uppfinningen kan framstdllas genom strdngsprutning av silikongummi som har en hardhet mellan 60 och 70 grader (International Rubber Hardness Degrees). Med detta material valies ldmpligen utstickningsvinkeln A for stbdribborna till att ligga mom omradet fran 30 till 60 grader far optimal verkan. Carpets according to the invention can be produced by extrusion of silicone rubber having a hardness between 60 and 70 degrees (International Rubber Hardness Degrees). With this material, the protrusion angle A for the stem slats is preferably selected to be within the range of 30 to 60 degrees for optimal effect.

Hojden och tjockleken hos stodribborna bor vdljas i samband med vinkeln A for att tillata en liten men vdsentlig deformation av stodribborna med ett lampligt kontakttryck. Vidare bar beaktas att den vertikala deformationen has stodribborna under kompressionen bor vara storre an den maximalt forvdntade forskjutningen av foremalet pa grund av vibrationer, far att kontakt mellan mattan och faremalet skall upprdtthallas. The height and thickness of the standing ribs should be chosen in connection with the angle A to allow a small but significant deformation of the standing ribs with a suitable contact pressure. Furthermore, it should be borne in mind that the vertical deformation of the standing ribs during compression should be greater than the maximum expected displacement of the forearm due to vibrations, so that contact between the mat and the forearm is maintained.

Den forskjutande mattan enligt fereliggande uppfinning kan givetvis sjdlv roterbart forflyttas i forhallande till ett ickecylindriskt fbremal, t ex en stang eller en folie, for att forflytta fOremalet i en ferbestamd riktning. Ett exempel pa ett sadant arrangemang visas i fig. 6, i vilken tva valsar 40 med motsatta drivningsriktningar är forsedda med forskjutningshylsor 41, vilka har stedribbor 42 anordnade parallella med rotationsriktningen. En rullande kontakt mellan hylsorna och ett arkformigt foremal 43 bringar faremalet att forflyttas i riktningen M som resultat av de tvd palagda rarelsekomposanterna R i rullningsriktningen och T i forskjutningsriktningen. Alternativt kan en enstaka ledarvdgg dessutom anvandas for att begransa rorelsen till enbart riktningen R. The offset mat according to the present invention can, of course, itself be rotatably moved in relation to a non-cylindrical surface, for example a rod or a foil, in order to move the object in a verb-determined direction. An example of such an arrangement is shown in Fig. 6, in which two rollers 40 with opposite driving directions are provided with displacement sleeves 41, which have location ribs 42 arranged parallel to the direction of rotation. A rolling contact between the sleeves and a sheet-shaped mold 43 causes the hazard to move in the direction M as a result of the two-ply grooved components R in the rolling direction and T in the displacement direction. Alternatively, a single guidewire can also be used to limit the movement to the direction R. only.
