Laite kappaleiden lastaamiseksi vaunukuljettimelle ja purka-miseksi vaunukuljettimelta TSman keksinndn kohteena on patenttivaatimuksen 1 johdannon mukainen laite kappaleiden lastaamiseksi vaunukuljettimelle ja purkamiseksi vaunukuljettimelta.The invention relates to a device according to the preamble of claim 1 for loading and unloading pieces from a carriage conveyor.

Vaunukuljettimia kSytetSSn tehtaissa ja tuotantolaitoksissa erityisesti kiinteiden kappaleiden siirtamiseen. Kuljetti-meen voidaan liittaa haluttaessa vaunuja, joilla voidaan siirtaa irtotavaraa. vaunukuljettimilla siirretaan esimer-kiksi paperirullia, pakkauslaatikoita ja malmeja. Vaunukul-jetin kulkee tehtaassa erityista rataa pitkin. Rata koostuu ohjauskiskossa kulkevasta ketjusta, joka vetaa ketjuun tasa-vaiein kiinnitettyja vaunuja. Vaunut kulkevat edelleen ra-taan kiinnitetyilia kiskoilla. Vaunukuljettimen ja kuljetin-radan rakenne voi vaihdella. Radan rakenne riippuu kuljetet-tavasta materiaalista ja siita, minkaiainen radan haluttu geometria tehdassalissa on.Wagon conveyors used in factories and production facilities, especially for moving fixed parts. If desired, wagons can be attached to the conveyor to transport bulk goods. wagon conveyors transfer, for example, rolls of paper, packing boxes and ores. The wagon conveyor runs along a special track in the factory. The track consists of a chain running on a guide rail which pulls carriages evenly attached to the chain. The carriages still run on rails attached to the track. The design of the wagon conveyor and the conveyor track may vary. The structure of the track depends on the material to be transported and the desired geometry of the track in the factory hall.

vaunukuljettimen etuna muihin kuljettimiin nåhden on se, ettå materiaalia voidaan kuljettaa helposti pitkiSkin matko-ja. Materiaalia ei mydskSSn tarvitse siirtaa kuljettimelta toiselle mutkissa, nousuissa ja laskuissa. Vaunukuljettimel-la oleva kappale on koko ajan poikittaissuunnassa samassa paikassa kuljetinradalla aina siihen saakka, kunnes se siirretaan pois radalta.The advantage of the wagon conveyor over other conveyors is that the material can be easily transported along the skis. The material does not need to be transferred from one conveyor to another during bends, ups and downs. The piece on the carriage conveyor is always in the transverse direction in the same place on the conveyor track until it is moved off the track.

Vaunukuljetin sopii hyvin paperirullien siirtamiseen paperi-tehtaissa. Rullia kuljettava kuljetin voi olla pysahtyva-kayntinen, jolloin koko kuljetin on pysaytettava, kun jol-lain asemalla halutaan lastata tavaraa kuljettimelle tai purkaa kuljettimelta, tai jatkuvatoiminen, jolloin kuljetet-tava materiaali lastataan liikkuvalle kuljettimelle.The trolley conveyor is well suited for moving paper rolls in paper mills. The conveyor conveying the rolls can be stationary, in which case the entire conveyor must be stopped when it is desired to load or unload the goods on the conveyor at the station, or continuous, in which case the material to be conveyed is loaded on the moving conveyor.

PysShtyvStoiminen kuljetin sopii parhaiten kayttfikohteisiin, joissa on vain vShSn purkaus- ja lastausasemia ja joissa 2 91514 vaadittava kuljetuskapasitetti on pieni ja tarvittavat siir-tomatkat kohtuullisen lyhyita. Kuljettimen pysayttaminen lastaamista ja purkausta vårten alentaa kapasiteettia ja lisaa vaadittavaa kuljetusaikaa. Pysahtyvatoiminen kuljetin voi pysahtya tasaisin aikavaiein, jolloin kuljetettavan ma-teriaalin lastaaminen tapahtuu tasaisin vaiiajoin kuljettimen ollessa pysahdyksissa. T3118in taytyy lastattavan mate-riaalin odottaa lastausasemalla kuljettimen pysahtymista. Kuljetin voi myCs pysahtya saatuaan lastausasemalta pysahty-miskaskyn. T3ssa tapauksessa laitteiston pysahdyksissaoloai-ka jaa hieman pienemmaksi kuin maaraajoin pysahtyvaiia lait-teella, jos lastausasemia on vahan.The stationary conveyor is best suited for applications where there are only vShS unloading and loading stations and where the required transport capacity of 2,91514 is small and the required transport distances are reasonably short. Stopping the conveyor during loading and unloading reduces capacity and increases the required transport time. The stationary conveyor can stop at regular intervals, in which case the loading of the material to be transported takes place at regular intervals when the conveyor is stationary. The T3118in has to wait for the material to be loaded at the loading station for the conveyor to stop. The conveyor may stop myCs after receiving a stop-stop from the loading station. In this case, the downtime of the equipment is slightly shorter than the downtime of the equipment on the device if there are loading waxes.

Jatkuvatoimiselle vaunukuljettimelle lastataan siirrettava materiaali kuljettimen ollessa liikkeessa. Kappaleiden siir-tamiseen kuljettimelle voidaan kayttaa kaltevia ramppeja tai erilaisia nostolaitteita. Sylinterimaisia kappaleita, kuten paperirullia kasiteltaessa on edullista kayttaa ramppeja rullien lastausasemilla. Kun rulla halutaan siirtaa kuljettimelle, tyOnnetaan se ramppia pitkin alas kuljettimen paai-le ja otetaan vastaan vastaanottimella. Rulla kiihtyy rullan ja kuljetinradan vaiisen kitkavoiman vaikutuksesta nopeasti kuljettimen nopeuteen. Kun rulla halutaan siirtaa pois kul-jettimelta, tyCnnetaan se tyflntimelia kuljetinradalta ram-pille. Rulla voidaan my8s nostaa radalle ja pois radalta erilaisilla nostolaitteilla. My8s nostolaitteita kaytettaes-sa rulla on kuljettimen liikesuunnan suhteen paikallaan niin kauan kunnes rulla lasketaan kuljettimelle, jolloin se kiihtyy radan liikenopeuteen kitkavoiman vaikutuksesta.The continuous wagon conveyor is loaded with material to be moved while the conveyor is in motion. Inclined ramps or various lifting devices can be used to transfer the pieces to the conveyor. When handling cylindrical pieces, such as paper rolls, it is advantageous to use ramps at roll loading stations. When it is desired to transfer the roll to the conveyor, it is pushed down the ramp onto the conveyor and received by the receiver. The roller accelerates rapidly to the speed of the conveyor due to the silent frictional force of the roller and the conveyor track. When it is desired to move the roll away from the conveyor, it is pushed from the conveyor track onto the ram. The roller can also be lifted on and off the track with various lifting devices. When using My8s hoists, the roller is stationary with respect to the direction of movement of the conveyor until the roller is lowered onto the conveyor, at which point it accelerates to the speed of movement of the track due to frictional force.

Vaikka vaunukuljettimen vaunujen ja radan nopeus on yleensa melko pieni, kohdistuu kuljettimelle siirrettavaan kappalee-seen lahtfinykays, joka saattaa vaurioittaa kappaletta. Sa-moin rullan ja vastaanottimen tai tyfintimen kosketuskohdassa tapahtuva liukuminen saattaa vaurioittaa rullaa. Rullavauri-oiden vahentamiseksi on kehitetty ty8ntimi3 ja vastaanotti-mia, jotka pystyvat seuraamaan rullan liiketta silloin kun 91514 3 rulla siirretaan liikkuvalle radalle kiinteaita alustalta ja vastaavasti kun rulla siirretaan radalta alustalle. Tanaiselia ratkaisulla vaitetaan rullan vaurioituminen tydntimen ja vastaanottimen kosketuskohdassa. Ratkaisun avulla rullavauriot vahenevat, mutta koska liukumista tapah-tuu edelleen rullan ja radan vaiilia seka rullan ja purkaus-rampin vaiilia, ei vauriotumista ole voitu kokonaan vaittaa. Jatkuvatoimisia vaunukuljettimia ei siten ole voitu kayttaa vaativien ja mekaanisesti heikkojen paperilaatujen kSsitte-lyyn.Although the speed of the carriages and the track of the carriage conveyor is usually quite low, the piece to be conveyed to the conveyor is subjected to a bump, which may damage the piece. Likewise, sliding at the point of contact between the roller and the receiver or typhin may damage the roller. In order to reduce roller damage, pushers and receivers have been developed which are able to monitor the movement of the roller when the roller is moved to a moving track from a fixed fence and when the roller is moved from the track to the base, respectively. The current solution alleges that the roller is damaged at the point of contact between the core and the receiver. With the solution, the roller damage is reduced, but since the sliding still takes place between the roller and the track ridge and the roller and the discharge ramp rake, the damage could not be completely ignored. Thus, continuous wagon conveyors have not been able to be used to handle demanding and mechanically weak paper grades.

Koska rullan ja radan vaiisen nopeuseron tasoittuminen ta-pahtuu hankautumisen ja kitkavoiman vaikutuksesta, ei nopeuseron tasaantuminen tapahdu aina samalla tavalla, mista syysta rullan asema radalla ja vaunussa vaihtelee satunnai-sesti seka riippuu rullan koosta. Rullan kulkuradan ja ase-man vaihtelu aiheuttaa hairidita lastausasemilla ja vaikeut-taa jarjestelman synkronointia ja ohjausta.Since the smoothing of the speed difference between the roller and the track occurs due to friction and frictional force, the leveling of the speed difference does not always occur in the same way, which is why the position of the roller on the track and the carriage varies randomly and depends on the size of the roller. Variation in the path and position of the roller causes trouble at the loading stations and makes it difficult to synchronize and control the system.

Tam3n keksinndn tarkoituksena on saada aikaan sellainen vau-nunkuljettimen lastaus- ja purkauslaite erityisesti paperi-rullia vårten, jonka avulla lastattavan tai purettavan kap-paleen liukuminen ja vaurioituminen voidaan vaittaa.The object of the present invention is to provide such a loading and unloading device for a wagon conveyor, in particular for paper rolls, by means of which the sliding and damage of the Kap piece to be loaded or unloaded can be prevented.

Keksintd perustuu siihen, etta vaunukuljettimelle siirretta-v3 kappale kiihdytetaan ennen kuljettimelle laskemista kul-jettimen kanssa samaan nopeuteen.The invention is based on the fact that the body v3 for the carriage conveyor is accelerated to the same speed as the conveyor before being lowered onto the conveyor.

Tasmailisemmin sanottuna keksinndn mukaiselle laitteelle on tunnusomaista se, mita on esitetty patenttivaatimuksen 1 tunnusmerkkiosassa.More specifically, the device according to the invention is characterized by what is set forth in the characterizing part of claim 1.

Keksinndn avulla saavutetaan huomattavia etuja.The invention provides considerable advantages.

Rullia lastatessa ja purettaessa ei esiinny liukumaa, minka ansiosta vaunukuljettimilla voidaan kasitelia ja siirtaa myds mekaanisesti heikkoja paperilaatuja. Paperirullan han-kautumisesta johtuvat tappiot poistuvat, koska hankautumista 91514 4 ei tapahdu. Purkaus- ja lastausasemien ja kuljettimen toi-minta on aikaisempaa helpompi synkronoida. Keksinnon mukaisen laitteen etuna on se, etta rullien vastaanottaminen asemalle ja luovutus asemalta seka asettaminen vaunuun ja ottaminen vaunusta ovat erillisiM tapahtumia ja tapahtumat voidaan ohjata toistumaan aina samaniaisina rullan dimensiosta riip-pumatta. Aikaisemmilla laitteilla vastaanottaminen/luovutus on tapahtunut yhtena vaiheena vaunun lastaamisen/purkamisen kanssa, ja koska rullan ja radan vSlisen nopeuseron tasoittu-minen on perustunut kitkavoimaan ja liukumaan, on nopeuseron tasoittuminen ollut osittain sattumanvaraista ja riippunut osittain rullan dimensioista. TMmS on aihettanut rullan kul-kuradan vaihteluita ja johtanut tapahtumien huonoon synkro-nointiin ja aiheuttanut hairidita jarjestelman toiminnassa. Keksinndn mukaisen laitteen avulla saadaan rullan rata pysy-maan aina samanlaisena, jolloin jarjestelman toimintavarmuus lisaantyy.There is no slippage when loading and unloading rolls, which allows the conveyor conveyors to handle and move myds of mechanically poor paper grades. Losses due to abrasion of the paper roll are eliminated because abrasion 91514 4 does not occur. Unloading and loading stations and conveyor operation are easier to synchronize than before. The advantage of the device according to the invention is that the receipt and delivery of the rolls to and from the station, as well as the placement and removal from the carriage, are separate events and the events can be controlled to always repeat the same regardless of the roll dimension. With previous devices, the receipt / delivery has taken place in one step with the loading / unloading of the carriage, and since the smoothing of the roller and track speed difference has been based on frictional force and slip, the speed difference smoothing has been partly random and partly dependent on the roller dimensions. TMmS has caused variations in the path of the roller and resulted in poor synchronization of events and caused a disturbance in the operation of the system. By means of the device according to the invention, the path of the roller can always be kept the same, whereby the operational reliability of the system is increased.

Keksintda tarkastellaan seuraavassa lahemmin oheisten pii- * rustusten avulla.The invention will now be discussed in more detail with the aid of the accompanying drawings.

Kuvio 1 esittaa yhta keksinndn mukaista laitetta edesta.Figure 1 shows a front view of one device according to the invention.

; Kuvio 2 esittaa kuvion 1 mukaista laitetta sivulta.; Figure 2 shows a side view of the device according to Figure 1.

Kuviossa 1 vaunukuljettimen rata 1 on keskimmaisena ja vaunu 2 kulkee rataa i pitkin laitteen keskelta. Lastauslaitteen runko 3 on rakennettu siten, etta sen sivuosat sijaitsevat radan 1 molemmilla puolilla, ja sivuosat on yhdistetty toi-siinsa radan 1 ali kulkevilla palkeilla. Runkoon 3 on nive-ldity neljaiia kammella nostopdyta 4. NostopOyta 4 koostuu kahdesta radan molemmin puolin sijaitsevasta osasta, jotka on yhdistetty toisiinsa radan 1 ali kulkevilla palkeilla. Kammet 6 ja 8 on kiinnitetty alapaistaan nivelilia li ja 15 nostopdytaan 4 ja yiapaistaan nivelilia 10 ja 14 runkoon 3.In Figure 1, the track 1 of the carriage conveyor is in the middle and the carriage 2 runs along the track i from the center of the device. The body 3 of the loading device is constructed in such a way that its side parts are located on both sides of the track 1, and the side parts are connected to each other by beams passing under the track 1. The frame 3 is hinged by four crank lifting platforms 4. The lifting platform 4 consists of two parts on both sides of the track, which are connected to each other by beams passing under the track 1. The cranks 6 and 8 are attached at their lower edges to the articulated sleeve 1 and 15 to the lifting table 4 and at the lower edges to the articulated body 10 and 14 to the body 3.

Kuviossa 1 on lastauslaitteen vasemmalla puolella lastaus-ramppi 5 ja oikealla vastaanotin 18. Vastaanotin on esitetty 5 91514 katkoviivoin uloimmaisessa asennossaan seka lepoasennossa. Lastauslaite soveltuu erikokoisille rullille. Kuvassa on esitetty suuri rulla 19 ja pieni rulla 20. Molemmat voidaan ot-taa vastaan vastaanottimella 18 ja laskea nostolaitteella vaunuun 2 ilman erillisia saatetoimenpiteita. Rullat 19, 20 asettuvat aina samalla tavoin vaunuun 2 sen keskilinjan koh-dalle.Figure 1 shows a loading ramp 5 on the left side of the loading device and a receiver 18 on the right. The receiver is shown in dashed lines 5 91514 in its outermost position as well as in the rest position. The loading device is suitable for rollers of different sizes. The figure shows a large roller 19 and a small roller 20. Both can be received by the receiver 18 and lowered by the lifting device into the carriage 2 without separate accompanying measures. The rollers 19, 20 always settle in the same way on the carriage 2 at its center line.

Kuviossa 2 on esitetty kuvion 1 laite sivulta. Kuvassa vau-nukuljettimen vaunun 2 kulkusuunta on nuolen mukaisesti oi-kealta vasenunalle. Lastauslaite on ala-asennossaan, ja lait-teen sijainti yiaasennossa on kuvattu katkoviivoin 17. Kun vaunuun 2 lastattava rulla 19 tulee rampille 5, vedetaan nostopdytaa 4 hydraulisylinterilia 16 vaunun 2 kulkusuuntaan nahden vastakkaiseen suuntaan. Koska kammet 6 ja 7 on kiin-nitetty yiapaistaan nivelilia 10 ja 12 kiinteaan runkoon 3 ja alapaistaan nivelilia 11 ja 13 nostopfiytaan 4, kaantyvat kammet 6 ja 7 yianivelten 10 ja 12 varassa. NostopGyta 4 ja runko on liitetty myOs radan toisella puolella vastaavasti toisiinsa kammilla ja nivelilia. Nostopdyta 4 paasee liikku-maan vaunun 2 kulkusuuntaan nahden vastakkaiseen suuntaan ja ylOspMin. Kammet 6 ja 7 kaantyvat yianivelten 10 ja 12 va-; rassa, jolloin alanivelet 11 ja 13 siirtyvat sellaisen ym- • pyrMn kaarta pitkin yldspMin ja vaunun 2 kulkusuuntaa vas taan, jonka sade on yhtasuuri kuin yianivelten 10 ja 12 etaisyys alanivelista 11 ja 13. Nivelten 10 ja li seka 12 ja 13 valinen etaisyys ja sylinterin 16 liikematka maarataan siten, etta alanivelten 11 ja 13 siirtyma h ylOspain vastaa vaunun 2 kuormatason ja rampin 5 valista korkeuseroa.Figure 2 is a side view of the device of Figure 1. Figure wow-nukuljettimen the vehicle 2 is traveling direction as indicated by arrow O, from right to vasenunalle. The loading device is in its lower position, and the position of the device in the yia position is illustrated by broken lines 17. When the roller 19 to be loaded on the carriage 2 enters the ramp 5, the lifting cylinder 4 hydraulic cylinder 16 is pulled in the opposite direction to the carriage 2. Since the cranks 6 and 7 are fixed to the fixed body 3 of the yia-jointed joints 10 and 12 and the joints 11 and 13 are lowered to the lifting surface 4, the cranks 6 and 7 turn on the yian joints 10 and 12. LiftingGyta 4 and the frame are connected on the other side of the myOs track with cranks and joints respectively. The lifting stop 4 is allowed to move in the opposite direction to the direction of travel of the carriage 2 and ylOspMin. Cranks 6 and 7 turn into joints 10 and 12; in which the lower joints 11 and 13 move along the arc of a circle • against the direction of travel of the general joint and the carriage 2, the rain of which is equal to the distance of the joints 10 and 12 from the lower joints 11 and 13 and the distance between the joints 10 and 12 and 13. 16 The travel is determined so that the displacement h ylOspain of the lower joints 11 and 13 corresponds to the difference in height between the load plane of the carriage 2 and the ramp 5.

Kun nostopdyta 4 on katkoviivojen 17 osoittamassa yiaasennossa, tydnnetaan rulla 19 ramppia 5 pitkin nostopdydaile 4. Rulla 19 otetaan vastaan vastaanottimella 18, joka hidastaa rulian 19 nopeuden ja pysayttaa rullan 19 nostopCydaile 4.When the lifting wheel 4 is in the yia position indicated by the broken lines 17, the roller 19 is filled along the ramp 5 by the lifting wheel 4. The roller 19 is received by a receiver 18 which slows down the speed of the roller 19 and stops the lifting wheel 4 of the roller 19.

Rulla 19 siirretaan nostopdydaita 4 vaunuun 2 seuraavalla tavalla: kun vaunu 2 on oikealla kohdalla nostopOydan 4 si-vuosien vaiissa, siirretaan nostopdytaa 4 sylinterilia 16 6 91514 vaunun 2 kulkusuuntaan. Nostopoytå 4 siirtyy kampien 6 ja 7 varassa seka kiertyen yianivelten 10 ja 12 ymp3ri vaunun 2 kulkusuuntaan ja alaspSin. Nostopdyta 4 ja silia oleva rulla 19 saavat vaunun 2 kulkusuuntaa ja nopeutta vastaavan nopeu-den, ja kun kammet 6 ja 7 ovat lahes pystysuorassa, ovat vaunun 2, rulian 19 ja nostopdydan 4 nopeudet samat. Rulla 19 koskettaa samalla hetkelia vaunun 2 kuormatasoon. Nostop3yta 4 laskeutuu viela hieman alaspain ja rulla 19 jaa vaunuun 2. Nostopdydan liikkeen pysahtyminen varmistetaan pysayttimelia 9.The roller 19 moves the lifting tables 4 to the carriage 2 as follows: when the carriage 2 is in the right position during the si years of the lifting table 4, the lifting cylinder 4 cylinders 16 6 91514 are moved in the direction of travel of the carriage 2. The lifting table 4 moves on the cranks 6 and 7 and rotates around the yian joints 10 and 12 in the direction of travel of the carriage 2 and downwards. The roller 19 of the lifting bed 4 and the Silia receive a speed corresponding to the direction and speed of the carriage 2, and when the cranks 6 and 7 are almost vertical, the speeds of the carriage 2, the roller 19 and the lifting bed 4 are the same. At the same time, the roller 19 momentarily contacts the load plane of the carriage 2. The lifting platform 4 still lowers slightly and the roller 19 divides the carriage 2. The movement of the lifting platform is stopped by the stopping melody 9.

Keksinndn mukaista laitetta voidaan kayttaa myds purkaus-laitteena. T311din laite sijoitetaan radan 1 suhteen siten, etta kun nostopdytaa liikutetaan sylinterilia 16, niin sy-linterin 16 ja nostopdydan 4 liikesuunta on sama kuin vaunu-jen 2 kulkusuunta. Jos vaunun 2 kulkusuunta on kuvion 2 nuolen mukainen, niin laite on asennettava painvastaiseen asentoon kuin se on kuvassa, eli sylinterin 16 puoleisen paan on oltava vasemmalla puolella.The device according to the invention can be used as a myds unloading device. The device T311d is positioned relative to the track 1 so that when the lifting cylinder is moved by the cylinder 16, the direction of movement of the cylinder 16 and the lifting bed 4 is the same as the direction of travel of the carriages 2. If the vehicle 2 is traveling direction of the arrow in Figure 2 wherein the device is installed in the opposite position as it is in the picture, a side end of the cylinder 16 is to be left.

Lastauslaitteen ja vaunukuljettimen toiminta tahdistetaan tavanomaisilla antureilla.The operation of the loading device and the wagon conveyor is synchronized with conventional sensors.

! T3man keksinndn toisessa suoritusmuodossa kammet ja nivelet on korvattu pydrilia ja raideparilla. T3ss3 suoritusmuodossa kiinteaan runkoon 3 on kiinnitetty kuljettimen radan 1 kans-sa yhdensuuntainen kaareutuva raidepari, jonka kaari suun-tautuu laskevasti kuljettimen liikesuuntaan. Nostoalustaan 4 on kiinnitetty pydrat, jotka on sovitettu kulkemaan raiteil-la niiden ohjaamina. Nostoalustan 4 toiseen p33h3n on lii-tetty lineaariliikkeen aikaansaava toimilaite 16 vastaavalla tavalla kuin edelia kuvatussa suoritusmuodossa. Niinpa nos-toalustaa 4 voidaan liikuttaa pydrilia raiteita pitkin toi-milaitteen 16 voiman avulla, mika aiheuttaa nostoalustalle 4 pystysuuntaisen ja vaakasuuntaisen liikeen raiteiden muodon mukaisesti. Raiteet voivat olla hyperbelin, e-funktion, ym-pyr3n, laskevan suoran tai jonkin muun sopivasti laskevan k3yr3n muotoisia.! In another embodiment of the present invention, the cranks and joints are replaced with pydril and a pair of rails. In the embodiment T3ss3, a pair of curved rails parallel to the track 1 of the conveyor is fixed to the fixed frame 3, the arc of which is decreasingly directed in the direction of movement of the conveyor. Attached to the lifting platform 4 are pillars adapted to run on the tracks under their guidance. A linear actuator 16 is connected to the second p33h3n of the lifting platform 4 in a manner similar to the embodiment described above. Thus, the lifting platform 4 can be moved along the pydril tracks by the force of the actuator 16, which causes the lifting platform 4 to move vertically and horizontally according to the shape of the tracks. The tracks may be in the form of a hyperbel, an e-function, a circle, a descending line, or some other suitably descending curve.

Keksinndn mukaisen laitteen rakenne voi poiketa tassa esite-tyista suoritusmuodoista. EsimerkissM olevan hydraulisylin-terin tilalla voi olla jokin muu suoraviivaisen liikkeen ai-kaansaava toimilaite, kuten kuularuuvi. Toimilaite voi tehda vetoliikkeen sijasta tyttntdliikkeen, jolloin se on sijoitet-tava lastauslaitteen vastakkaiselle puolelle. NostopOytaa voidaan liikuttaa vaihtoehtoisesti asentamalla johonkin yia-nivelista pydrivan liikkeen aikaansaava toimilaite. Sopivia vaihtoehtoja ovat mm. sahkdmoottori ja alennusvaihde seka erilaiset hydraulimoottorit. Kampien lukumaara ja sijoittelu voivat poiketa t3ss3 esitetyista neljasta rungon ja nosto-pdydan vaiiin sijoitetusta kammesta. Kammet voidaan sijoit-taa kokonan nostopdyddn alle tai yiapuolelle. Rungon raken-netta on tietenkin muutettava vastaavasti. Kampia voi olla useampia kuin nelja, ja etenkin sijoitettaessa kammet nosto-pdydan alle, voidaan kayttaa kahta, tai jopa yhta vahvara-kenteista kampea.The structure of the device according to the invention may differ from the embodiments presented here. The hydraulic cylinder in Example M may be replaced by another actuator that provides a linear motion, such as a ball screw. The actuator can make a filling movement instead of a pulling movement, in which case it must be placed on the opposite side of the loading device. Alternatively, the lifting arm can be moved by installing an actuator in one of the yia joints that causes a swirling motion. Suitable alternatives include e.g. electric motor and reduction gear as well as various hydraulic motors. The number and arrangement of the cranks may differ from the four cranks placed in the frame of the frame and lifting table shown in t3ss3. The cranks can be placed under or above the entire lifting table. The structure of the frame must, of course, be changed accordingly. There can be more than four cranks, and especially when placing the cranks under the lifting table, two, or even one, strong cranks can be used.

Keksinndn mukainen laite soveltuu parhaiten sylinterimaisten kappaleiden, kuten paperirullien, kasittelyyn, mutta taman toimintaperiaatteen mukaisesti voidaan rakentaa lastaus- ja purkauslaitteita, jotka soveltuvat muunkinmuotoisille kappa-leille ja muille materiaaleille.The device according to the invention is best suited for handling cylindrical parts, such as paper rolls, but according to this operating principle, loading and unloading devices suitable for other shapes and other materials can be built.
