Abstract

This invention concerns a studding machine comprising a mainly vertical stand (1), which on top has a horizontally projecting beam (2), on which a pair of stud guns (3) with their control devices (4) are hung, and lower down has a mainly pedal controlled bearer (6) for a tyre (7) which is to be studded, which is lockable in its working position. The stud gun (3) is designed so that, after its point has been manually placed against a stud hole (7a) in the tyre (7) the tyre (7) is drawn into a working position above a support (6a) in the bearer, the point (3a) is pressed fully into the bottom of the stud hole (7a), a stud is inserted (12) and then the gun returns to its start position.<IMAGE>

Description

8402522-0 Denna uppfinning syftar till att eliminera nämnda olägenheter. This invention aims at eliminating said inconveniences.

Detta syfte tillgodoses genom att uppfinningen avser en an- läggning där dubbningen kan utföras endast på ett noggrant i förväg bestämt ställe, varigenom dubbningens stödkropp kan vara så smal att den kan användas vid alla däck, oavsett storlek. Uppfinningen uppvisar de i patentkravets 1 känneteck- nande del angivna särdragen.This object is achieved in that the invention relates to a plant where the dubbing can be carried out only at a carefully predetermined place, whereby the support body of the dubbing can be so narrow that it can be used on all tires, regardless of size. The invention has the features stated in the characterizing part of claim 1.

Bifogade figurer visar en utförandeform av uppfinningen.The attached figures show an embodiment of the invention.

Därvid visar figurerna 1 och 2 dubbningsmaskinen i frontvy respektive sidovy, medan figurerna 3 och 4 visar två olika skeden av dubbningen. En dubbpistol 3 är fäst vid en axel 8, som kan förskjutas axialt och är vridbart lagrad i ett rör 15 som förbundits medelst parallellarmar 16 med ett skiv- formigt manöverelement 4. Manöverelementet 4 är i sin tur förskjutbart anordnat längs en axel 2 vinkelrätt mot skivans plan. Pistolen är sålunda förskjutbar i riktning av alla huvudaxlar och vridbar kring axeln 8 parallellt med däckets rotationsplan. Följaktligen har säkerställts, att dubbpistolen i dubbníngsögonblicket kan bringas i exakt rätt arbetsläge.Figures 1 and 2 show the dubbing machine in front view and side view, respectively, while Figures 3 and 4 show two different stages of the dubbing. A stud pistol 3 is attached to a shaft 8, which can be displaced axially and is rotatably mounted in a tube 15 which is connected by means of parallel arms 16 to a disc-shaped operating element 4. The operating element 4 is in turn slidably arranged along a shaft 2 perpendicular to the disc. plan. The gun is thus displaceable in the direction of all main axes and rotatable about the axis 8 parallel to the plane of rotation of the tire. Consequently, it has been ensured that the stud pistol can be brought into exactly the correct working position at the moment of dubbing.

Däcket 7 som ska dubbas placeras på en nedsänkt stödkropp 6a, som genom en pedal 5 kan höjas, varvid däcket följer med. Efter detta bringas däcket att rotera runt sin medelpunkt, stött på de rullar Ga som stödkroppen uppvisar. vidiaubbning förs aubbpistolens 3 spets zain i det hål va i däcket 7, som befinner sig närmast pistolens arbetsläge.The tire 7 to be studded is placed on a lowered support body 6a, which can be raised by a pedal 5, the tire accompanying. After this, the tire is caused to rotate around its center, encountered with the rollers Ga shown by the support body. vidiaubbning, the tip zain of the aub pistol 3 is moved into the hole va in the deck 7, which is closest to the working position of the gun.

Till axeln 8 har med hjälp av parallellarmar 16 kopplats en gränslägesbrytare 9, vilken ger en andra anordning 11 en startimpuls efter det att spetsen 3atqw*ts tillräckligt djupt in i hålet 7a. Anordningen 11 drar medelst spetsen 3a hos dubbpistolen 3 hålet 7a hos däcket 7 till exakt rätt arbetsläge, rakt ovanför den förhållandevis smala stödkroppen 6a hos bäranordningen 6. När hålet 7a befinner sig i exakt rätt arbetsläge, trycker en första anordning 10 omedelbart och automatiskt dubbpistolens 3 spets 3a i botten av hålet 8402522-0 och applicerar sålunda dubben på plats och för därefter spetsen 3a tillbaka ut ur hàlet 7a. Anordningarna 10 och 11 består av cylindrar med kolvar.A limit position switch 9 has been connected to the shaft 8 by means of parallel arms 16, which gives a second device 11 a starting pulse after the tip 3atqw * ts has been sufficiently deep into the hole 7a. The device 11 pulls by means of the tip 3a of the stud pistol 3 the hole 7a of the tire 7 to exactly the correct working position, directly above the relatively narrow support body 6a of the support device 6. When the hole 7a is in exactly the correct working position, a first device 10 immediately and automatically pushes the stud pistol 3 tip 3a at the bottom of the hole 8402522-0 and thus applies the stud in place and then moves the tip 3a back out of the hole 7a. The devices 10 and 11 consist of cylinders with pistons.

Dubbningsmaskinens arbetstakt kan forceras, om den förses med två stycken pistoler 3, en för vardera kant av däcket.The working rate of the dubbing machine can be forced, if it is provided with two pistols 3, one for each edge of the tire.

Aktionen säkerställs och/eller underlättas: om axeln 8 är kullagrad om arbetstakten hos anordningarnas 10 och 11 kolvar är reglerbar medelst en strypventil om manöverelement 4 är låsbart i lägen motsvarande däckens lägen vid olika däckstorlekar om bäranordningens 6 stödkropp 6a har en rulle 6b i mitten om bäranordningen 6 är vridbar kring vertikalaxeln för att underlätta däckets placering pà plats.The action is ensured and / or facilitated: if the shaft 8 is ball-bearing if the working rate of the pistons of the devices 10 and 11 is adjustable by means of a throttle valve if the control element 4 is lockable in positions corresponding to the tire positions at different tire sizes if the support body 6a has a roller 6b the support device 6 is rotatable about the vertical axis to facilitate the placement of the tire in place.
