150939150939

Opfindelsen vedrører et apparat til foldning af rektangulære tøjstykker, navnlig tværfoldning, og omfattende en foldeenhed, en første og en anden føler anbragt i indbyrdes afstand i en transportørs transportretning 5 til aftastning af tøjstykkets position på transportøren i transportretningen, samt to aftastningsorganer til aftastning af tøjstykkets position på transportøren vinkelret på transportretningen.The invention relates to an apparatus for folding rectangular pieces of clothing, in particular cross-folding, and comprising a folding unit, a first and a second sensor spaced apart in a conveyor direction 5 for sensing the position of the piece of clothing on the conveyor in the direction of transport, and two sensing means for scanning the piece of clothing. position of the carrier perpendicular to the direction of transport.

Fra DE-AS 1 585 882 kendes et apparat af den ind-10 ledningsvis nævnte art. Apparatet omfatter to aftastningsorganer, der er anbragt på en fælles linie vinkelret på transportretningen og omtrent midtvejs mellem henholdsvis en forreste og en bageste kantføler. Aftastningsorganerne er lejret forskydeligt og bevæges under 15 drift mod hinanden med henblik på at bestemme'det aktuelle tøjstykkes udstrækning vinkelret på transportretningen.DE-AS 1 585 882 discloses an apparatus of the kind mentioned above. The apparatus comprises two sensing means arranged on a common line perpendicular to the direction of transport and approximately midway between a front and a rear edge sensor, respectively. The sensing means are mounted slidably and moved during operation towards each other in order to determine the extent of the actual piece of clothing perpendicular to the direction of transport.

Apparatet ifølge nærværende opfindelse adskiller sig fra det kendte apparat ved, at de på hver sin side 20 af foldeenheden placerede aftastningsorganer ligger på en på transportretningen vinkelret og gennem den i transportretningen anden føler gående linie.The apparatus according to the present invention differs from the known apparatus in that the sensing means located on either side 20 of the folding unit is located on a perpendicular to the direction of transport and through the other sensor in the direction of transport.

Ved denne placering af aftastningsorganerne opnås, at det på enkel måde er muligt at afgøre, om et givet 25 tøjstykke er oprettet som ønsket, dvs. med forkanten vinkelret på transportretningen.At this location of the sensing means, it is achieved that it is easy to determine whether a given piece of clothing is created as desired, ie. with the leading edge perpendicular to the direction of transport.

Opfindelsen forklares nærmere i det følgende ' under henvisning til tegningen, hvor fig. 1 skematisk viser apparatet til foldning 30 ifølge opfindelsen, fig. 2 et snit efter linien II-II i fig. 1, fig. 3 snittet II-II med gengivelse af et til foldning egnet stykke tøj, fig. 4 snittet II-II med gengivelse af et for 35 langt stykke tøj, 150939 2 fig. 5 snittet II-II med gengivelse af et for langt til venstre på transportøren lagt stykke tøj, fig. 6 snittet II-II med gengivelse af et for langt til højre på transportøren lagt stykke tøj, 5 fig,; 7 snittet II-II med gengivelse af et styk ke tøj, der er for smalt, fig. 8 snittet II-II med gengivelse af et stykke tøj, der både er for langt og for smalt, og fig. 9 og 10 snittet II-II med gengivelse af et 10 stykke tøj, der er lagt på skrå på transportøren.BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 schematically shows the apparatus for folding 30 according to the invention; FIG. 2 is a sectional view taken along line II-II of FIG. 1, FIG. 3 is a sectional view II-II showing a piece of clothing suitable for folding; FIG. 4 shows the section II-II with the representation of an excessively long piece of clothing, FIG. 5 shows the section II-II with a piece of clothing placed too far to the left on the conveyor; FIG. 6 shows the section II-II with representation of a piece of clothing placed too far to the right, 5 fig.; 7 is a sectional view II-II showing a piece of clothing that is too narrow; FIG. 8 is a sectional view II-II showing a piece of clothing that is both too long and too narrow; and FIG. 9 and 10 are sections II-II with a reproduction of a 10-piece garment placed on the conveyor.

Som det fremgår af fig. 1 og 2, er der i et stativ 1 drevne valser 2 og 3, om hvilke der løber transportremme 4. Transportremmene tjener til at fremføre et stykke tøj 5 til en foldemekanisme.As shown in FIG. 1 and 2, there are rollers 2 and 3 driven in a rack 1 about which conveyor belts 4 run. The conveyor belts serve to convey a piece of clothing 5 to a folding mechanism.

15 Over transportremmene 41 s transportplan er der tværstillede trykvalser 6 og 7, der kan bevæges til deres arbejdsstilling ved hjælp af en arbejdscylin-der 8. Ligeledes er der over transportremmene 41 s transportplan et anslag 9, der aktiveres ved hjælp af 20 en arbejdscylinder 10.15 Above the conveyor belts 41 s conveying plane, there are transverse pressure rollers 6 and 7 which can be moved to their working position by means of a working cylinder 8. Also, there is an abutment 9 activated by the conveying belts 41 s conveying plane 10 by means of a working cylinder 10. .

Ved afgangssiden af stativet 1 er der et af- _ læggerbord 11, hvortil tøjstykker 5, der ikke er egnet til foldning, transporteres ved hjælp af transportremmene 4.At the departure side of the rack 1, there is a deposition table 11 to which pieces of clothing 5 which are not suitable for folding are conveyed by means of the conveyor belts 4.

25 Ved foldning stoppes transportremmene 4, og trykvalserne 6 og 7 bevæges af arbejdscylinderen 8 til anlæg mod tøjstykket, hvorved dette trykkes ned gennem transportplanet til indgreb med foldevalser 12 og 13. Det ved hjælp af disse valser foldede stykke 30 tøj 5 bliver af ikke viste transportmidler ført til et bord 14.25 During folding, the conveyor belts 4 are stopped and the pressure rollers 6 and 7 are moved by the working cylinder 8 to abut the piece of clothing, which is pressed down through the transport plane for engagement with folding rollers 12 and 13. The piece of clothing 30 folded by these rolls is not shown. means of transport brought to a table 14.

Til detektering af størrelsen og placeringen af tøjstykket 5 er der dels en første føler 15 ved tilgangen til foldemekanismen, dels en anden føler 17 for-35 an anslaget 9. Endvidere er der på begge sider af den anden føler 17 aftastningsorganer 16 og 18. Følerne 150939 3 15 og 17 har til opgave at sammenligne tøjstykket 5's længde B i fremføringsretningen med den forudbestemte afstand, der er mellem følerne 15 og 17, medens af-tastningsorganerne 16 og 18 på lignende måde tjener 5 til at registrere tøjstykket 5's bredde L vinkelret på fremføringsretningen. Herudover registrerer aftastningsorganerne 16 og 18 tøjstykket 5's opretning.For detecting the size and location of the garment 5, there is a first sensor 15 at the approach to the folding mechanism and a second sensor 17 in front of the stop 9. Furthermore, on both sides of the second sensor 17 there are sensing means 16 and 18. The sensors The task of comparing the length B of the clothing piece 5 in the feed direction is with the predetermined distance which is between the sensors 15 and 17, while the sensing means 16 and 18 similarly serve 5 to detect the width L of the clothing piece 5 perpendicularly. the feed direction. In addition, the sensing means 16 and 18 record the alignment of the clothing piece 5.

Apparatet til foldning arbejder som følger:The folding apparatus works as follows:

Som det fremgår af fig. 3, bliver et tøjstykke 10 5, hvis længde B er mindre end afstanden mellem føler ne 15 og 17, og som ligger vinkelret på transportretningen, fremført til foldestationen af transportremmene 4. Herved sker der en aktivering af den første føler 15, og den her opståede impuls oplagres. Ved videre 15 bevægelse af tøjstykket bliver den første føler 15 igen nulstillet, og følerne 16, 17 og 18 aktiveres.As shown in FIG. 3, a piece of clothing 10 5, the length B of which is less than the distance between sensors 15 and 17, and which is perpendicular to the direction of transport, is conveyed to the folding station of the conveyor belts 4. This activates the first sensor 15, and this one impulse generated is stored. Upon further movement of the garment, the first sensor 15 is reset again and the sensors 16, 17 and 18 are activated.

Da længden B af tøjstykket 5 er mindre end afstanden mellem følerne 15 og 17 (fig. 3), og da endvidere aftastningsorganerne 16 og 18 er aktiveret, forbliver 20 tøjanslaget 9 i den nederste stilling. Samtidig standses driften af transportremmene 4. Efterløbet af remmene 4 vælges således, at tøjstykket 5 netop ligger an mod anslaget 9, for derved at korrigere for eventuelle mindre afvigelser fra den retvinklede 25 opretning. Efter standsning af remmene 4 indledes foldningen ved, at trykvalserne 6 og 7 trykker tøjstykket 5 ned mellem foldevalserne 12 og 13. Samtidig kan der ske en passende centrering, idet organerne 16 og 18 efter standsning af remmene 4 an-30 vendes som følere for foldning på midten.Since the length B of the garment 5 is less than the distance between the sensors 15 and 17 (Fig. 3), and furthermore, the sensing means 16 and 18 are activated, the 20 abutment 9 remains in the lower position. At the same time, the operation of the conveyor belts 4 is stopped. The aftermath of the belts 4 is chosen so that the piece of clothing 5 abuts precisely against the stop 9, thereby correcting for any minor deviations from the right-angled alignment. After stopping the belts 4, folding is initiated by the pressure rollers 6 and 7 depressing the piece of clothing 5 between the folding rollers 12 and 13. At the same time, an appropriate centering can be done, the means 16 and 18, after stopping the belts 4, being used as sensors for folding. in the middle.

Sammenfattende bliver der til denne foldning gennemført følgende forløb, idet de anvendte symboler har følgende betydning: 150939 4In summary, the following steps are carried out for this folding, the symbols used having the following meaning:

Trykvalse (6, 7) : O = Trykvalserne befinder sig i afstand fra transportremmene 4, 5 L = trykvalserne ligger an mod tøj- stykket, så at dette gribes af foldevalserne og foldes.Pressure rollers (6, 7): O = The pressure rollers are at a distance from the conveyor belts 4, 5 L = the pressure rollers abut the piece of clothing, so that it is gripped by the folding rollers and folded.

Tøjanslag (9) : 0 = Tøjanslaget befinder sig umiddelbart over transport-10 remmene 4 og dermed i ar bejdsstilling, L = tøjanslaget er løftet og ude af funktion, Følere (15, 16, 15 17, 18) : 0 = Føleren er ikke aktiveret, L = føleren er aktiveret.Clothes stop (9): 0 = The clothes stop is immediately above the transport belts 4 and thus in working position, L = the clothes stop is lifted and out of function, Sensors (15, 16, 15 17, 18): 0 = The sensor is not activated, L = sensor is activated.

Herved opnås der en korrekt foldning af tøjstyk- 25 ket.Hereby a correct folding of the garment is obtained.

I alle andre tilfælde skal tøjstykket 5 ikke foldes i foldeapparatet, men tilføres aflæggerbordet 11 uden foldning. Hertil skal der i det følgende gives nogle eksempler: 30 Foreligger der et stykke tøj 5 med for stor længde b (fig. 4), så vil følerne (15, 16, 17 og 18) være dækket, og tøjanslaget 9 vil ikke være aktiveret.In all other cases, the piece of clothing 5 should not be folded into the folding apparatus, but fed to the deposition table 11 without folding. Here are some examples: 30 If a piece of clothing 5 of excessive length b (Fig. 4) is available, then the sensors (15, 16, 17 and 18) will be covered and the clothing stop 9 will not be activated .

Det for lange stykke tøj føres derfor videre af remmene 4 til aflæggerbordet 11 uden tværfoldning.The too long piece of clothing is therefore carried by the belts 4 to the deposition table 11 without cross-folding.

En yderligere mulighed er, at tøjstykket 5 pålægges forskudt til venstre (fig. 5). Et sådant tøjstykke 5 ligger uden for midterkorrektionsområdet for foldningen og må ligeledes fraskilles. Her dækkes kun fø-10 lerne 17 og 18, medens den tredje føler 16 forbliver fri. Anslaget 9 bliver igen ført op, og tøjstykket 5 passerer apparatet uden tværfoldning.A further possibility is that the piece of clothing 5 is placed offset to the left (Fig. 5). Such a piece of clothing 5 lies outside the center correction area of the fold and must also be separated. Here, only the sensors 17 and 18 are covered, while the third sensor 16 remains free. The stop 9 is raised again and the piece of clothing 5 passes the apparatus without cross-folding.

Ved indføring af et stykke tøj 5, der er for 30 smalt (fig. 7), sker der ligeledes kun aktivering af føleren 17, så at tøjstykket 5 transporteres videre uden at være foldet.Also, when inserting a piece of clothing 5 that is too narrow (Fig. 7), only the sensor 17 is activated so that the piece of clothing 5 is transported further without being folded.
