Abstract

The invention concerns a device for automatical capture of soft, flimsy articles such as towels, sheets and garments. The work is today mostly performed manually because it is difficult to capture the article in a controlled way. The invention solves the problem. The device consists of two endless belts (2, 3) stretched over a roller (4) and a shaft (5) each and arranged so that they under springforce can run against each other. One of the belts (2) has elements (11) which at contact with the article (1) capture a part of it and thereby one layer only. The belts are rotated and the article is drawn in between the belts and held fast. A mechanism (10) separates the belts when to release the article. The sensor (13) detects the position of the article.

Description

----< 501 300 .2 lO 15 20 25 30 35 Den andra gaffeln (7) är fjädrande upphängd sa att den trycks mot gaffeln (6) i en mutter (9) vilken är rörligt lagrad i fästet (8) och förskjutbar med en skruv (10). ---- <501 300 .2 10 15 20 25 30 35 The second fork (7) is resiliently suspended so that it is pressed against the fork (6) in a nut (9) which is movably mounted in the bracket (8) and slidable with a screw (10).

Arrangemanget gör att även valsarna och banden kommer att tryckas mot varandra och sålunda utöva en hållande kraft pâ alstret när detta kommit in mellan banden.The arrangement means that the rollers and the belts will also be pressed against each other and thus exert a holding force on the article when this has entered between the belts.

Fjäderkraften kan varieras. ' A I stället för skruv och mutter kan andra mekanismer (10) för att dra isär och ihop valsarna tänkas. Den ena eller den andra gaffeln kan vara fast förbunden med fästet (8) och den ena eller bada gafflarna rörliga.The spring force can be varied. 'A Instead of screw and nut, other mechanisms (10) for pulling apart and assembling the rollers are conceivable. One or the other fork can be fixedly connected to the bracket (8) and one or both forks movable.

Det ena bandet (2) är för att öka greppet mot alstret pa i varje fall del av sin utâtvända yta utformat för vidhäftning och/eller med extra hög friktion så att vid ingreppstillfället endast ett lager av alstret uppfângas eller försett med organ (ll), taggar, enligt fig 3 visade i överdriven skala._ Taggarna är i detta fall fjädrande. Som fjädrar fungerar bandet självt. Taggarna trycks ut lagom mycket för uppfângning av endast ett lager av alstret (l) när de passerar tappen (5) och fjädrar tillbaka när inte längre något mothâll finns. För att förhindra att taggarna» trycks ut då de passerar valsen (4) är denna försedd med runtomkringgàende spår vari taggens skalle får plats.One band (2) is for increasing the grip against the article on in each case part of its outwardly facing surface designed for adhesion and / or with extra high friction so that at the time of engagement only a layer of the article is captured or provided with means (II), tags, according to Fig. 3 shown in excessive scale._ The tags are resilient in this case. Like feathers, the band works itself. The spikes are pushed out just enough to catch only one layer of the article (1) when they pass the pin (5) and spring back when there is no longer any resistance. To prevent the tags »from being pushed out as they pass the roller (4), this is provided with circumferential grooves in which the skull of the tag can fit.

Annan utformning av organen (ll) år givetvis möjlig så länge dessa är utformade så att endast ett lager fångas upp. Ûrganen (ll) och bandet (2) utformas så att alstret lätt släpper vid bandens utgàngssida. Utformningen av bandet (2) för vidhäftning kan vara kardborreliknande eller på annat sätt taggig och/eller av kemisk natur. För att förhindra att bandet (3) oavsiktligt också drar med sig en bit av alstret in mellan banden kan bandet (3) göras med låg ytfriktion eller erhålla ett skydd mot kontakt med alstret vid uppfángningen.Other design of the means (II) is of course possible as long as these are designed so that only one layer is captured. The organ (II) and the belt (2) are designed so that the article easily releases at the exit side of the belts. The design of the tape (2) for adhesion may be velcro-like or otherwise prickly and / or of a chemical nature. To prevent the belt (3) from inadvertently also dragging a piece of the article in between the belts, the belt (3) can be made with low surface friction or obtain a protection against contact with the article during collection.

Till den ena valsen (4) är kopplat en motor eller annat vriddon. Rotationsrörelsen överförs fràn den ena valsen till den andra via kugghjul (12). Genom att välja kugghjul med förhållandevis stor modul kommer dessa att 10 15 20 25 30 35 fortfarande vara i ingrepp med varandra även om valsarna trycks isär av alstret. Eftersom banden (2,3) är spända över valsarna (4) kommer även banden att rotera da valsarna roterar.A motor or other torque is connected to one roller (4). The rotational movement is transmitted from one roller to the other via gears (12). By selecting gears with a relatively large module, these will still be in engagement with each other even if the rollers are pushed apart by the article. Since the belts (2,3) are tensioned over the rollers (4), the belts will also rotate as the rollers rotate.

Anordningen är vidare utrustad med en avkännare (13).The device is further equipped with a sensor (13).

Denna kan vara mekanisk eller elektronisk. I fallet mekanisk år avkännaren utrustad med en mätspets som kan skjutas ut och in. Avkånnaren detekterar alstrets läge i rörelseriktningen för anordningens positioneringsdon och ger en signal till detta att t.ex stanna just när alstret nås.This can be mechanical or electronic. In the case of mechanical years, the sensor is equipped with a measuring tip that can be slid in and out. The sensor detects the position of the article in the direction of movement of the positioning device of the device and gives a signal to this to, for example, stop just when the article is reached.

Valsarna (4) kan förses med en backspärr (ej visat) fär an. farhinuz-a latfpbanden börjar rater-a a: :ei han om lasten pa motorn skulle bli för stor.The rollers (4) can be fitted with a backstop (not shown). farhinuz-a latfpbanden begins rater-a a:: ei he if the load on the engine would be too large.

Pâ gafflarnas översida kan sättas självlasande element, klaffar, (ej visat) som hindrar alstret (l) att glida mellan banden (2,3).On the upper side of the forks, self-locking elements, flaps (not shown) can be placed which prevent the article (1) from sliding between the straps (2,3).

Anordningen fungerar pâ följande sätt.The device works as follows.

Anordningen positioneras mot rätt läge. Taggarna (ll) eller motsvarande pa bandet (2) år riktade mot alstret.The device is positioned towards the correct position. The tags (ll) or equivalent on the band (2) are directed towards the product.

Här avkånnaren detekterar alstrets yta ges signal till positioneringsdonet om kontrollerat stopp. I fallet mekanisk avkänning gar nu avkånnarens mätspets undan.Here the sensor detects the surface of the article, a signal is given to the positioning device about a controlled stop. In the case of mechanical sensing, the measuring tip of the sensor now goes away.

Taggarna träffar med förutbestämd kraft precis alstrets yta och rotationen av banden startas. Taggarna kommer nu att gripa tag i alstrets yta och endast i ett lager och på grund av rotationen föra med sig en liten del av alstret in mellan banden. Anordningens positioneringsdon påbörjar sin förflyttning. Alstret förs nu fram mellan banden och hålls fast av dessa. I Rotationen får vid behov fortsätta så länge att en gripbar flik (14) har utbildats vid bandens utgàngssida.The thorns strike with predetermined force exactly the surface of the product and the rotation of the bands is started. The tags will now grip the surface of the article and only in one layer and due to the rotation bring a small part of the article in between the bands. The positioning device of the device begins to move. The article is now advanced between the straps and held by them. If necessary, the rotation may continue until a tangible flap (14) has been formed at the exit side of the belts.

Fliken kan gripas av t.ex en klämma. När denna har stängt eller när alstret skall släppas, säras gafflarna (6,7) genom att vrida skruven (10) och alstret lossas från anordningen. Banden roteras tills taggarna eller motsvarande återigen befinner sig 1 uppfângninglåge, gafílarna körs ihop och proceduren kan upprepas.The tab can be gripped by, for example, a clamp. When this has closed or when the article is to be released, the forks (6,7) are separated by turning the screw (10) and the article is detached from the device. The straps are rotated until the spikes or the like are again in a catch position, the forks are moved together and the procedure can be repeated.

Anordningen är i första hand tänkt för uppiangning av mjuka, sladdriga, platta alster såsom handdukar, badhanddukar, andra tygstycken. lakan osv men också för t.ex plagg ochThe device is primarily intended for hanging soft, fluffy, flat articles such as towels, bath towels, other pieces of cloth. sheets etc. but also for eg garments and
