Description

Opfindelsen angår et til indføring af vasketøjsstykker til ruller eller lignende vasketøjsbehandlingsmaskiner, hvilket apparat er af den nærmere i krav l's indledning angivne art.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a roll-in or roll-out washing machine, which is of the kind specified in the preamble of claim 1.

i 150660in 150660

Fra det tyske brugsmønster nr. 72 13 450 kendes et indfø-5 ringsapparat, hvor vasketøjsstykket med sine hjørner manuelt indklemmes i gribeorganerne, hvorefter gribeorganerne udfører en bort fra hinanden rettet bevægelse og dermed udbreder vasketøjsstykket. I den udbredte tilstand bliver tværdrageren nu forskudt i indføringstransportørens fremførings-10 retning, hvorefter gribeorganerne åbnes, og det et vist stykke hen over indføringstransportøren førte vasketøjsstykke frigives, således at dets forreste endekant falder ned på indføringstransportøren. Under vasketøjsstykkets indtrækning vender tværdrageren igen tilbage til sin udgangs-15 stilling og kan forsynes med et yderligere stykke vasketøj.From German usage pattern no. 72 13 450 there is known an introducing apparatus in which the laundry piece with its corners is manually squeezed into the gripping means, after which the gripping means performs a movement apart and thus spreads the laundry piece. In the widened state, the transverse carrier is now displaced in the feed direction of the feed conveyor, after which the gripping means are opened and a certain piece of laundry carried along the feed conveyor is released, so that its front end edge falls down on the feed conveyor. During the retraction of the laundry piece, the transverse carrier returns to its initial position again and can be provided with an additional piece of laundry.

Medens den forreste endekant på vasketøjsstykket frigives og falder ned, er vasketøjsstykket overvejende overladt til sig selv. Det kan derfor let ske, at den forreste endekant ombøjes, eller at vasketøjsstykket forskydes på indfø-20 ringstransportøren, således at det ikke bliver muligt at indføre vasketøjsstykket vinkelret i rullen eller i vasketøj sbehandlingsmaskinen. Helt bortset fra betydelige konstruktive omkostninger er der desuden ingen sikkerhed for, at vasketøjsstykket kan blive indført nøjagtigt i midten af 25 rullen, hvilket især er af betydning, når der er tilsluttet sammenlægningsindretninger til rullen.While the front end edge of the laundry piece is released and falls down, the laundry piece is predominantly left to itself. Therefore, it can easily happen that the front end edge is bent or the laundry piece is displaced on the feed conveyor so that it is not possible to insert the laundry piece perpendicularly to the roller or the washing machine. Furthermore, apart from considerable construction costs, there is no assurance that the laundry piece can be inserted exactly in the middle of the roll, which is especially important when connecting rollers are connected to the roll.

Det er opfindelsens formål at anvise udformningen af et apparat af den indledningsvis nævnte art, der ikke er behæftet med de nævnte ulemper, og dette formål opnås ved et 30 apparat, som ifølge opfindelsen tillige udviser de i krav l's kendetegnende del angivne træk.It is an object of the invention to provide the design of an apparatus of the kind mentioned above, which does not suffer from the disadvantages mentioned, and this object is achieved by an apparatus which also according to the invention exhibits the features of claim 1.

Herved opnås en forenkling af vasketøjsstykkets fastklemning og udbredning, en efter ønske nøjagtigt i midten eller sideforskudt indføring af vasketøjsstykket og fremfor alt 150660 2 en sådan forbedring af vasketøjsstykkets afgivelse til indføringstransportøren, at der sikres en nøjagtig retvinklet eller kantrettet indføring af et stykke vasketøj i rullen eller en anden vasketøjsbehandlingsmaskine.Hereby, a simplification of the clamping and spreading of the laundry piece is achieved, a desired exactly in the middle or laterally displaced insertion of the laundry piece and, above all, such an improvement in the delivery of the laundry piece to the insert conveyor that a precisely rectangular or angled insertion of the laundry is ensured. or another laundry treatment machine.

5 At der med et sådant i .føringsapparat kan opnås et særligt enkelt bevægelsesforløb ved indføringen af vasketøjsstykket i en rulle eller lignende maskine, hvor der er sikkerhed for, at vasketøjsstykket indføres kantrettet og efter ønske i midten eller forskudt fra midten, skyldes, at gribeorga-10 nerne ikke lader vasketøjsstykket falde på indføringstransportøren, men snarere overgiver det tvangsstyret til indføringstransportøren i den ønskede stilling, således at de i forbindelse med de kendte indføringsapparater omtalte ulemper ikke kan optræde. Som følge af, at den med hvert gribe-15 organs overdel forbundne valse beskriver en drejningseller svingbane, der på tænkt vis forløber gennem indføringstransportørens plan, opnås, at valsen under tværdragerens drejning trykker og på en vis måde udglatter det forreste det forreste endekantområde på vasketøjsstykket mod 20 indføringstransportøren, medens vasketøjsstykket begynder at løsnes fra gribeorganerne. Eftersom gribeorganets overdel, hvorpå valsen er anbragt, er anbragt elastisk eftergivende og svingbart i forhold til underdelen, trænger valsen i virkeligheden ikke gennem indføringstransportørens 25 plan, men bliver ført langs dette plan under afgivelse af et fjedertryk, hvilket samtidigt bevirker, at det indklemte vasketøjsområde frigives. Dette skyldes, at der ved valsens berøring med indføringstransportøren sker en automatisk 30 åbning af gribeorganet under tværdragerens drejning, eftersom den drejeligt lejrede overdel imod indvirkningen fra en fjederkraft fjernes fra den stive underdel, som under tværdragerens drejning ikke kommer i berøring med indføringstransportøren.5 With such a guide device, a particularly simple course of movement can be achieved by the insertion of the laundry piece into a roll or similar machine, where there is a certainty that the laundry piece is inserted at an angle and, if desired, in the middle or offset from the middle, due to gripping organs. -10 does not allow the laundry piece to fall onto the feed conveyor, but rather, it surrenders the forced guide to the feed conveyor in the desired position so that the disadvantages referred to in the prior art feed apparatus cannot occur. As the roller associated with the upper part of each gripper member describes a pivot or pivot path which is thought to extend through the plane of the feed conveyor, it is achieved that during the rotation of the transverse carrier the roller presses and in some way smoothes the front end edge region of the laundry piece. toward the insertion conveyor while the laundry piece begins to detach from the gripping means. Since the upper member of the gripper on which the roller is placed is resiliently resilient and pivotal with respect to the base, the roller does not, in fact, penetrate through the plane of the feed conveyor 25, but is passed along this plane during release of a spring pressure, which simultaneously causes the clamped laundry area released. This is because, when the roller is in contact with the feed conveyor, an automatic opening of the gripper occurs during the rotation of the cross carrier, since the rotatably mounted upper part is removed from the rigid base which, during the rotation of the cross carrier, does not come into contact with the feed conveyor.

35 På denne måde kan det også sikres, at gribeorganernes begyndende åbning under vasketøjsstykkets anbringelse på indfø- 150660 3 ringstransportøren bliver låst eller arreteret, indtil gribeorganerne på ny er ført tilbage til stillingen for pålægning af det næste stykke vasketøj.In this way, it can also be ensured that the initial opening of the gripping means during the application of the laundry piece to the feeding conveyor is locked or arrested until the gripping means are returned again to the position for placing the next piece of laundry.

Det er også muligt ifølge opfindelsen kun at anbringe ét par 5 gribeorganer på tværdrageren, hvilket bevirker, at tværdrageren må drejes 360° under en indføringsbevægelse. Det er dog også muligt at anbringe to modstående par gribeorganer på tværdrageren, således at denne kun behøver at drejes 180°.It is also possible according to the invention to place only one pair of 5 gripping means on the transverse carrier, which causes the transverse carrier to be rotated 360 ° during an insertion movement. However, it is also possible to place two opposite pairs of gripping means on the transverse carrier so that it only needs to be rotated 180 °.

10 Opfindelsen vil i det følgende blive nærmere forklaret i forbindelse med nogle udførelseseksempler og under henvisning til tegningen, hvor fig. 1 viser et indføringsapparat set forfra, fig. 2 det i fig. 1 viste indføringsapparat, set fra siden, 15 fig. 3 til 5 forskellige bevægelsesfaser for indførings-apparatet, set fra siden, skematisk og i større målestokforhold, fig. 6 perspektivisk et gribeorgan, fig. 7 og 8 et længdesnit gennem en tværdrager med en 20 indretning til midtstilling af et par gribeorga ner, fig. 9 et længdesnit gennem en tværdrager med to over for hinanden anbragte par gribeorganer, fig. 10 det i fig. '9 viste, set fra siden, og 25 fig. 11 en anden udførelsesform for det i fig. 8 og 9 viste.The invention will be explained in more detail below with reference to some embodiments and with reference to the drawing, in which: FIG. 1 is a front view of an insertion apparatus; FIG. 2 shows the embodiment of FIG. 1 is a side view of the insertion apparatus shown in FIG. Figures 3 to 5 show different stages of movement of the feeder, schematically and on a larger scale, fig. 6 is a perspective view of a gripper; FIG. 7 and 8 are a longitudinal section through a transverse carrier with a device for centering a pair of gripping means; 9 is a longitudinal section through a transverse carrier with two opposite pairs of gripping means; FIG. 10 shows the embodiment of FIG. 9 is a side view, and FIG. 11 shows another embodiment of the embodiment shown in FIG. 8 and 9.

I det i fig. 1 og 2 viste udførelseseksempel ses grundprincippet for indføringsapparatet ifølge opfindelsen.In the embodiment of FIG. 1 and 2, the basic principle of the insertion apparatus according to the invention is shown.

I en vis afstand over en indføringstransportør 11 er anbragt en tværdrager 1, drejeligt lejret om sin længdeakse. På 30 denne tværdrager 1 er et par gribeorganer 2 og eventuelt et par gribeorganer 3 forskydeligt anbragt langs tværdragerens længdeakser. Tværdrageren 1 bliver i modsætning til, hvad der er tilfældet i den kendte teknik, ikke bevæget på tværs af sin akse. Drejningen af tværdrageren 1 udføres af en mo- 150660 4 tor 4, som via tandhjul 5,6 og en kæde 7 påvirker akselen på tværdrageren 1. På denne aksel findes desuden en skive 8, der er forsynet med hak, som arreteringselementer 9 kan gå i indgreb med. Så snart arreteringselementet 9 5 går i indgreb med et hak i skiven 8, spærres motoren 4's rotationsdrev. Når der på tværdrageren 1 kun er anbragt et par gribeorganer 2, kan tværdrageren 1 mellem arrete-ringerne dreje en hel omdrejning. Er tværdrageren 1 derimod, som vist i fig. 1 og 2, forsynet med to over for 10 hianden anbragte par gribeorganer 2,3, har skiven 8 to modstående hak, således at der opnås en afslutning af drejningsbevægelsen allerede efter 180° drejning af tværdrageren 1.At a certain distance above an insertion conveyor 11 is arranged a transverse carrier 1, pivotally mounted about its longitudinal axis. On this transverse carrier 1, a pair of gripping means 2 and optionally a pair of gripping means 3 are slidably disposed along the longitudinal axes of the transverse carrier. Contrary to what is known in the prior art, the transverse carrier 1 is not moved across its axis. The rotation of the transverse carrier 1 is carried out by a motor 4, which via gear 5,6 and a chain 7 influences the shaft of the transverse carrier 1. On this shaft there is also a disc 8, which is provided with notches, which the arresting elements 9 can go in engagement with. As soon as the fixing element 9 5 engages with a notch in the disc 8, the rotational drive of the motor 4 is blocked. When only a few gripping means 2 are arranged on the transverse carrier 1, the transverse carrier 1 can rotate in full rotation between the latches. On the other hand, as shown in FIG. 1 and 2, provided with two pairs of gripping means 2.3 positioned opposite 10, the disc 8 has two opposite notches, so that a rotation of the turning movement is obtained already after 180 ° rotation of the transverse carrier 1.

Funktionen af indføringsapparatet ses i fig. 3 til 5, me-15 dens en konstruktiv udformning af et enkelt gribeorgan er vist perspektivisk i fig. 6, hvor en skematisk rulle er betegnet med henvisningstallet 12, og vasketøjsstykket har henvisningstallet 10.The operation of the feeding apparatus is shown in FIG. 3 to 5, while a constructive design of a single gripper is shown in perspective in FIG. 6, where a schematic roller is designated by reference numeral 12 and the laundry piece has reference numeral 10.

Som vist i fig. 3 bliver den forreste kant på vasketøjs-20 stykket 10 anbragt mellem de enkelte gribeorganers overdel 14 og underdel 13, som Vist i fig. 6, hvor gribeorganerne i fig. 2 til 5 er vist skematisk med henvisningsbetegnelserne 2 hhv. 3. Tværdrageren 1 bliver nu fra den i fig. 3 viste stilling drejet om sin drejningsakse 33 i retning 25 med uret, således at gribeorganerne 2 nærmer sig indføringstransportøren 11.As shown in FIG. 3, the leading edge of the laundry piece 10 is placed between the upper part 14 and the lower part 13 of the individual gripping means, as shown in FIG. 6, wherein the gripping means of FIG. 2 to 5 are shown schematically with reference numerals 2 and 2 respectively. 3. The transverse carrier 1 now becomes from the one shown in FIG. 3, rotated about its axis of rotation 33 in a clockwise direction 25 so that the gripping means 2 approach the feed conveyor 11.

1 den i fig. 4 viste mellemstilling er en på gribeorganets 2 overdel 14 anbragt valse 15 nærmet indføringstransportøren 11 så meget, at denne valse 15 begynder at trykke 30 vasketøjsstykket 10 mod indføringstransportøren 11. Underdelen 13 på gribeorganet 2 kommer under drejningen af tværdrageren 1 ikke i berøring med indføringstransportøren 11.1 shows the one in FIG. 4, a roller 15 located on the upper part 14 of the gripper member 2 is adjacent the feeder conveyor 11 so much that this roller 15 begins to press the laundry piece 10 towards the feeder conveyor 11. The member 13 of the gripper member 2 does not touch the feeder conveyor 11 during the rotation of the transverse conveyor 11 .

Når valsen 15 rammer indføringstransportøren 11, bliver overdelen 14 på gribeorganet 2 drejet om drejningsaksen 34 150660 5 i retning mod uret og imod indvirkningen fra en fjeder 16. Derved bliver overdelen 14 og underdelen 13 frigjort fra hinanden, hvilket bevirker frigivelse af den forreste, tidligere indklemte kant på vasketøjsstykket 10. Denne 5 stilling er vist i fig. 5. Under den videre drejning af tværdrageren 1 stryger valsen 15 nu vasketøjsstykkets frigjorte kant af imod indføringstransportøren 11 og danner derved med indføringstransportøren et klemvalse-par, som bevirker en sikker indtrækning af vasketøjsstyk-10 ket 10 i rullen 12 eller lignende maskine, uden at den forreste frigjorte kant på vasketøjsstykket 10 forskydes eller endog bliver slået om.When the roller 15 strikes the feed conveyor 11, the upper part 14 of the gripper means 2 is rotated about the axis of rotation 34 in a counterclockwise direction and against the action of a spring 16. Thus, the upper part 14 and the lower part 13 are released from each other, which causes release of the front, earlier clamped edge of the laundry piece 10. This position is shown in FIG. 5. During the further rotation of the transverse carrier 1, the roller 15 now erases the detached edge of the laundry piece against the insertion conveyor 11, thereby forming with the insertion conveyor a clamping roller pair which causes a secure insertion of the laundry piece 10 into the roller 12 or similar machine. the leading released edge of the laundry piece 10 is displaced or even reversed.

Under den videre drejning af tværdrageren 1 fjernes de to gribeorganer fra indføringstransportøren 11, medens de to 15 gribeorganer 3 føres til en modtagelsesstation til indklem-ning af et næste stykke vasketøj.During further rotation of the transverse carrier 1, the two gripping means are removed from the feed conveyor 11, while the two 15 gripping means 3 are led to a receiving station for squeezing a next piece of laundry.

For at gribeorganerne ifølge opfindelsen skal kunne gennemføre denne funktion, må nogle betingelser opfyldes. Som allerede tidligere nævnt må den i fig. 6 viste underdel 13 20 for gribeorganerne 2 eller 3 være således udformet og dimensioneret, at den frie kant på underdelen 13 ikke eller kun i ringe grad kommer i berøring med indføringstransportøren 11.In order for the gripping means according to the invention to be able to perform this function, some conditions must be fulfilled. As already mentioned earlier, in FIG. 6, for the gripping means 2 or 3, is shown to be designed and dimensioned so that the free edge of the lower part 13 does not, or only slightly, contact the insertion conveyor 11.

Den nævnte underdel 13 på gribeorganerne 2,3 er i det viste 25 udførelseseksempel stift udformet. Den har en klemplade 35, som på sin frie kant er afrundet eller affaset, således at ingen kant kan danne folder i eller beskadige det indklemte stykke vasketøj 10.Said lower part 13 of the gripping means 2,3 is rigidly formed in the illustrated example 25 shown. It has a clamping plate 35 which is rounded or beveled at its free edge so that no edge can form folds or damage the clamped piece of laundry 10.

Overdelen 14 på gribeorganerne 2,3 er om drejningsaksen 34 30 drejeligt lejret på den stationære underdel 13 og belastet med en fjeder 16, hvis fjederkraft er rettet således, at de to gribeorgandele 13,14 normalt trykkes mod hinanden. Ved den frie kant på overdelen 14 findes en drejeligt lejret valse 15, hvis drejningsakse forløber parallelt med drej- 150660 6 bi den frie kant på underdelen 13 eller dennes klemplade 35. Afstanden til rullen 15 fra drejningsaksen 33 for tværdrageren 1 er således afpasset, at valsen 15 under drejning af tværdrageren 1 teoretisk må føres gennem det øverste løb 5 på indføringstransportøren 11. Eftersom overdelen 14 med valsen 15 imidlertid er lejret svingbart og elastisk eftergivende, kommer rullen 15 til at stryge langs det øvre løb på indføringstransportøren 11, hvorved der som nævnt fås en svingbevægelse for overdelen 14 i retning mod uret 10 om aksen 34.The upper part 14 of the gripping means 2,3 is rotatably mounted on the rotary shaft 34 30 on the stationary lower part 13 and is loaded with a spring 16, the spring force of which is directed so that the two gripping members 13, 14 are normally pressed against each other. At the free edge of the upper part 14 is a pivotally mounted roller 15, whose axis of rotation extends parallel to the free edge of the lower part 13 or its clamping plate 35. The distance to the roller 15 from the axis of rotation 33 of the transverse carrier 1 is adjusted so that The roll 15 during rotation of the transverse carrier 1 must theoretically be passed through the upper run 5 of the feed conveyor 11. However, since the upper part 14 with the roll 15 is bearably pivotally and resiliently resilient, the roll 15 will iron along the upper run of the feed conveyor 11, whereby as mentioned, a swivel movement for the upper part 14 is obtained in a counterclockwise direction 10 about the axis 34.

Denne svingbevægelse for overdelen 14 kan nu udnyttes til at arretere det derved dannede åbningssted for delene 13,14 i gribeorganerne 2,3 ifølge fig. 5 urider den videre bevægelse af tværdrageren 1. Med henblik herpå er der på under-15 siden af overdelen 14 anbragt et anslag eller stoporgan 17, som er rettet mod underdelen 13 eller klempladen 35. På denne klemplade 35 findes en bladfjeder 18 med knaster eller modanslag 32, imod hvilke stoporganet 17 lægger an under drejningsbevægelsen. Derved springer stoporganet 17 20 over anslaget 32 og går således i indgreb med bladfjederen 18, at delene 13,14 i det i fig. 6 viste bevægelsesforløb bliver arreteret i åbningsstillingen.This pivotal movement of the upper part 14 can now be utilized to arrest the opening position thus formed for the parts 13,14 of the gripping means 2,3 according to FIG. 5, the further movement of the transverse carrier 1. exits. For this purpose, a stop or stop means 17 is arranged on the lower side of the upper part 14, which is directed towards the lower part 13 or the clip plate 35. On this clip plate 35 is a leaf spring 18 with knobs or counter-stop 32 against which the stop member 17 engages during the rotational movement. Thereby, the stop member 17 20 skips the stop 32 and so engages with the leaf spring 18 that the parts 13, 14 in the embodiment shown in FIG. 6, the movement sequence shown is arranged in the opening position.

I denne i fig. 6 viste stilling vender de enkelte gribeor-ganer på ny tilbage til betjeningsstationen. Ønskes et 25 vasketøjsstykke 10 indklemt i gribeorganerne 2,3, behøver bladfjederen 18 kun at trykkes en smule nedad. Derved går stoporganet 17 fri af bladfjederen 18, hvilket bevirker, at overdelen 14 under indvirkning af fjederen 16 trykkes ned mod underdelen 13,35 og fastklemmer vasketøjsstykket 10.In this embodiment of FIG. 6, the individual gripping means return to the operating station again. If a laundry piece 10 is desired to be squeezed into the gripping means 2,3, the leaf spring 18 only needs to be pressed down slightly. Thereby, the stop means 17 is released from the leaf spring 18, which causes the upper part 14, under the action of the spring 16, to be pressed down against the lower part 13,35 and clamps the laundry piece 10.

30 Fig. 6 viser desuden, at de enkelte gribeorganer 2,3 er ført forskydeligt langs en løbeskinne 20, der udgør en del af den i fig. 6 ikke nærmere viste tværdrager 1. Sidebevægelsen for gribeorganerne 2,3 sker via et snoretræk 21, som er fastklemt til underdelen 13 i gribeorganerne 2,3. Denne 35 underdel 13 er desuden ved hjælp af vinkelstykker 19 forbundet med føringsorganerne inde i løbeskinnen 20.FIG. 6 further shows that the individual gripping means 2,3 are slidably guided along a running rail 20 which forms part of the part shown in FIG. 6 not shown in cross-sections 1. The lateral movement of the gripping means 2,3 is via a string 21 which is clamped to the lower part 13 of the gripping means 2,3. This lower part 13 is further connected by means of angular pieces 19 to the guide means inside the running rail 20.

150660 7 I forbindelse med det i fig. 7 og 8 viste skal det nu forklares, hvorledes de enkelte gribeorganer 2 fra en sideforskudt stilling i forhold til rullens indtrækningsplan ved simple midler kan forskydes til en midterstilling. Snore-5 eller kabeltrækket 21 er, som det fremgår af fig. 6, ført i en rundtgående endeløs bane inde i tværdrageren 1. Ved det øverste løb i snoretrækket 21 er det ene gribeorgan fastgjort, medens det andet gribeorgan er fastgjort til det nederste løb i snoretrækket 21. Snoretrækket 21 er ende-10 løst ført over venderuller 24,25,26 og 27. Venderullen 24 er forbundet med en linearmotor 29, såsom en trykmedium-cylinder, og er indrettet til at forskydes langs længdeaksen for tværdrageren 1. De to venderuller 25,26 er stationært lejret, hvorimod venderullen '26 til gengæld er 15 forskydeligt lejret i længderetningen af tværdrageren 1 og påvirket af en fjeder 28.In connection with the embodiment of FIG. 7 and 8, it will now be explained how the individual gripping means 2 can be shifted from a laterally displaced position relative to the retraction plane of the roll by simple means to a central position. The cord 5 or cable pull 21 is as shown in FIG. 6, guided in an circumferential endless path within the transverse carrier 1. At the upper barrel of the bar 21, one gripping means is secured, while the other gripper is secured to the lower bar of the bar 21. The bar 21 is finally loosely passed over the rollers. 24,25,26 and 27. The turning roller 24 is connected to a linear motor 29, such as a pressure medium cylinder, and is arranged to be displaced along the longitudinal axis of the transverse carrier 1. The two turning rollers 25,26 are stationary, whereas the turning roller '26 to in turn, 15 is slidably mounted longitudinally of the transverse carrier 1 and influenced by a spring 28.

Det antages, at de to gribeorganer 2 i deres udgangsstilling indtager en fra midten forskudt stilling, hvor det ene gribeorgan har afstanden y og det andet gribeorgan afstanden x 20 til indføringsapparatets midterakse. Denne fra midten forskudte udgangsstilling for gribeorganerne 2 er gunstig, fordi det ofte er nødvendigt eller hensigtsmæssigt at indføre vasketøjsstykkerne forskudt fra midten i rullen eller lignende maskiner, hvilket fremfor alt gælder mindre vaske-25 tøjsstykker. Såfremt der på tværdrageren 1 er anbragt to modstående par gribeorganer, er det hensigtsmæssigt at have en spejlbilledmæssig fra midten forskudt udgangsstilling for gribeorganerne 2,3, især med henblik på at lade det samme apparat betjene af to personer i vekselvis 30 arbejdstakt, idet det antages, at den ene person anbringer sig til venstre og den anden person til højre for indføringsstedet.It is assumed that the two gripping means 2 in their initial position assume a position offset from the center, whereby one gripping means has the distance y and the other gripping means the distance x 20 to the center axis of the insertion apparatus. This center-shifted starting position for the gripping means 2 is advantageous because it is often necessary or appropriate to introduce the laundry pieces offset from the center into the roll or similar machines, which is particularly the case for smaller laundry pieces. If two opposing pairs of gripping means are arranged on the transverse carrier 1, it is convenient to have a mirror-displaced starting position of the gripping means 2,3, in particular in order to allow the same apparatus to be operated by two persons in alternating 30 operating rates, assuming , one person sits to the left and the other person to the right of the insertion point.

Et i praksis fordelagtigt indføringsapparat må dog også have mulighed for at få indført vasketøjsstykker nøjagtigt 35 i midten i rullen. Dertil tjener linearmotoren 29, som er i stand til at forskyde venderullen 24 stykket (x + y): 2.However, a practically advantageous insertion apparatus must also have the possibility of introducing laundry pieces exactly 35 in the center of the roller. In addition, the linear motor 29, capable of displacing the turning roller 24, serves the piece (x + y): 2.

150660 88

Denne forskydningsbevægelse bevirker en reaktion på venderullen 26, der som følge af stramningen i snoretrækket 21 forskydes fra den i fig. 7 viste stilling til den i fig. 8 viste og derved spænder fjederen 28. Ved denne påvirkning 5 af snoretrækket 21, der opfører sig efter taljeprincippet, bliver de enkelte gribeorganer 2 indstillet til samme afstand x fra indføringsapparatets længdemidterakse. I den i fig. 8 viste stilling er det nu sikret, at et vasketøjs-stykke, som kan indlægges i gribeorganerne 2, virkelig kan 10 indføres nøjagtigt i midten af rullen.This shear movement causes a response to the turning roller 26 which, as a result of the tightening in the drawbar 21, is displaced from the one shown in FIG. 7 to the position shown in FIG. 8 and thereby tensioning the spring 28. By this action 5 of the drawbar 21, which behaves according to the waist principle, the individual gripping means 2 are adjusted to the same distance x from the longitudinal center axis of the feeder. In the embodiment shown in FIG. 8, it is now ensured that a laundry piece which can be inserted into the gripping means 2 can really be inserted exactly in the middle of the roller.

I fig. 9 er vist den spejlbilledmæssigt forsatte udgangsstilling for gribeorganerne 2,3 i forhold til indførings-apparatets længdemidterakse.In FIG. 9, the starting position of the mirror image is set for the gripping means 2,3 relative to the longitudinal center axis of the insertion apparatus.

Ved vasketøjsstykkets indspænding i gribeorganerne 2 befin-15 der disse sig i en stilling meget tæt ved hinanden. Vasketø jsstykket må således udbredes, før end det kan overgives til indføringstransportøren 11. Med henblik herpå er der nu i hvert snoretræk 21 indrettet en linearmotor 22, såsom en trykmediumcylinder, hvis cylindersvøb fortrinsvis holdes 20 stationært, medens stempelstangen 23 er fast forbundet med det øverste løb i snoretrækket 21. Når derpå stemplet 23 ved hjælp af et egnet hydraulisk eller pneumatisk medium bevæges i forhold til trykmediumcylinderen 22, sker der i afhængighed af forskydningsretningen for stemplet 23 en 25 bevægelse af de enkelte gribeorganer i retning mod hinanden eller bort fra hinanden. I sidstnævnte tilfælde bliver det i gribeorganerne 2 indspændte vasketøjsstykke udbredt. I den udbredte tilstand virker der nu en friktionskraft mellem gribeorganerne 2,3 og vasketøjsstykket 10, og 30 størrelsen af denne friktionskraft kan anvendes som styremiddel til standsning af forskydningsbevægelsen af tryk-mediumcylinderen 22. Derpå kan drejebevægelsen af tværdrageren 1 sættes i gang ved kontaktomstilling.Upon clamping of the laundry piece into the gripping means 2, these are in a position very close to each other. Thus, the laundry piece must be extended before it can be passed to the feed conveyor 11. For this purpose, there is now arranged in each bar 21 a linear motor 22, such as a pressure medium cylinder, whose cylinder casing is preferably held 20 stationary, while the piston rod 23 is firmly connected to the upper one. 21, when the piston 23 is moved relative to the pressure medium cylinder 22 by means of a suitable hydraulic or pneumatic medium, a movement of the individual gripping members towards one another or away from each other occurs, depending on the displacement direction of the piston 23. In the latter case, the laundry piece clamped in the gripping means 2 becomes widespread. In the widespread state, a frictional force now acts between the gripping means 2,3 and the laundry piece 10, and the magnitude of this frictional force can be used as a control means for stopping the shear movement of the pressure medium cylinder 22. Then the rotary movement of the transverse carrier 1 can be started by contact adjustment.

Når der nu, som det fremgår af fig. 9, på hvert af to mod-35 stående sider af tværdrageren 1 er anbragt et par gribeor- 150660 9 ganer 2 hhv. 3, er det hensigtsmæssigt at styre linearmotorerne 22,30 på indbyrdes modsat vis, således at gribeorga-nerne 2 på indføringssiden bevæges bort fra hinanden, medens gribeorganerne 3 på den modstående side føres i retning mod 5 hinanden^ og omvendt. På denne måde opnås, at der under ud-bredningen af et vasketøjsstykke, der skal indføres, sker en forskydning mod hinanden af de over for liggende gribe-organer, som således ved ankomsten til indføringsstillingen indtager en position, der gør det muligt bekvemt at indspæn-10 de det efterfølgende vasketøjsstykke i gribeorganerne. Med henblik herpå er det endda kun nødvendigt at anbringe linearmotorerne 22,30 diagonalt over for hinanden til drejningsaksen 33 for tværdrageren 1, således som det fremgår af fig. 10. Derved bliver linearmotorerne 22,30 modsat påvirket.Now, as shown in FIG. 9, on each of two opposing sides of the transverse carrier 1 are arranged a pair of gripping means 2 and 2, respectively. 3, it is convenient to control the linear motors 22,30 in a mutually opposite manner, so that the gripping means 2 on the insertion side are moved away from one another, while the gripping means 3 on the opposite side are directed towards each other and vice versa. In this way, it is achieved that during the propagation of a piece of laundry to be inserted, a displacement is made against each other by the opposite gripping means, which thus, upon arrival at the insertion position, occupies a position which makes it convenient to clamp -10 they the subsequent laundry piece in the gripping means. For this purpose, it is even necessary only to place the linear motors 22.30 diagonally opposite each other to the axis of rotation 33 of the transverse carrier 1, as shown in FIG. 10. In this way, the linear motors 22.30 are adversely affected.

15 I det i fig. 11 viste udførelseseksempel ses en udvekslingsindretning til forskydning af gribeorganparrene 2,3 efter taljeprincippet. De to venderuller 41,42, omkring hvilke snoretrækket 21 er ført, er forbundet med stempelstangen 37 i en eneste trykmediumcylinder 36. Den ene ende af snore-20 trækket er via en fjeder 38 fastgjort til trykmediumcylinder en 36, medens den anden ende af snoretrækket er stationært fastgjort. En forskydning af venderullen 41 mod venstre bevirker en forskydning af snoretrækket 21 i den viste pils retning, hvorved de to gribeorganer 2 fjernes fra hinanden, 25 og de to gribeorganer 3 nærmer sig hinanden. Desuden er et gribeorgan i gribeorganparret 2,3 fastgjort til det øverste løb, medens det andet gribeorgan i gribeorganparret 2,3 er fastgjort til det underste løb af snoretrækket 21, der igen er ført over venderullerne 39,40.15 In the embodiment of FIG. 11 shows an exchange device for displacing the gripper member pairs 2.3 according to the waist principle. The two turning rolls 41, 42, around which the drawbar 21 is guided, are connected to the piston rod 37 in a single pressurized medium cylinder 36. One end of the drawstring 20 is attached via a spring 38 to the pressurized medium cylinder 36, while the other end of the drawstring is fixed stationary. An offset of the turning roller 41 to the left causes an offset of the drawbar 21 in the direction of the arrow shown, removing the two gripping means 2 from each other, 25 and the two gripping means 3 approaching each other. In addition, a gripper member in the gripper member pair 2,3 is attached to the upper barrel, while the second gripper member of the gripper member pair 2,3 is attached to the lower barrel of the bar 21, which is again passed over the turning rollers 39,40.
