Teleskopisk tårn BaggrundTelescopic Tower Background

Opfindelsen angår et system til pakning af især juletræer* hvilket system omfatter en løftekasse monteret bevægelig på teleskopiske søjler, der ved deres øvre ender er forbundet med en overligger.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a system for packing especially Christmas trees, which comprises a lifting box mounted movably on telescopic columns connected at their upper ends to a bar.

De kendte systemer til pakning af især juletræer er store og er derfor ofte besværlige at transportere.The known systems for packing especially Christmas trees are large and are therefore often difficult to transport.

Det er et formål med opfindelse at anvise et system til pakning af juletræer, der ikke har disse ulempenIt is an object of the invention to provide a system for packing Christmas trees which do not have these disadvantages

Det er tillige et formål med opfindelsen at anvise et alternativt system til pakning af juletræer.It is also an object of the invention to provide an alternative system for packing Christmas trees.

Dette opnås ved, at søjlerne er udført med en teleskopisk del, og at løftekassen er forbundet med søjlerne og den teleskopiske del således, at løftekassen kan bevæges fra en nedre position, hvor overliggeren ligger an mod en øvre ende på søjlerne til en øvre position, hvor den teleskopiske del er udskudt således, at overliggeren ikke længere ligger an mod den øvre ende af søjlerne, men derimod støttes af den teleskopiske del.This is accomplished by the columns being provided with a telescopic portion and the lifting box being connected to the columns and the telescopic portion so that the lifting box can be moved from a lower position where the overlayer abuts an upper end of the columns to an upper position. wherein the telescopic portion is projected so that the overlap no longer abuts the upper end of the columns, but is supported by the telescopic portion.

Detailed description

Med udgangspunkt i de viste figurer, særligt fi|, 4, er der vist ét tårn til pakning af særligt juletræer. I de kendte tårne ér din samlede højde H over 4 meter og dette medfører problemer på de danske (og udenlandske veje). Tårnet 5, 5' vist i figur 4 er derfor udført med en overligger 1, som kan hæves fra den viste position og sænkes l§éri til den viste position.On the basis of the figures shown, especially FIG. 4, one tower is shown for the packing of special Christmas trees. In the known towers your total height H is over 4 meters and this causes problems on the Danish (and foreign roads). The tower 5, 5 'shown in Fig. 4 is therefore constructed with an overlap 1 which can be raised from the position shown and lowered to the position shown.

Maskinen vist i figur 4 omfatter et tårn 1, én løftekasse 2, der er fastgjort til tårnet og som kan forskydes lodret, oftest ved hjælp en hydraulisk cylinder (ikke vist). Løftekassen holdes i position pi tårnet ved hjælp af glidestyr 1, 3',4,4'·The machine shown in Figure 4 comprises a tower 1, one lift box 2 which is attached to the tower and which can be displaced vertically, most often by means of a hydraulic cylinder (not shown). The lifting box is held in position in the tower by means of sliding guides 1, 3 ', 4.4' ·

Under løftekassen er normalt placeret en specielt indrettet palle fried seks lodrette støtter, dér er tilpasset seks komplementære glidestyr indvendigt i kassen, (disse er ikke vist i figur 4, men de lodrette støtter kan ses i figur 6 med nurhmerhenvisning 20, 20', 20",)Underneath the lift box is a specially arranged pallet fried six vertical supports, where six complementary sliding guides are fitted inside the box (these are not shown in figure 4, but the vertical supports can be seen in figure 6 with nurhmer reference 20, 20 ', 20 ")

Pakning af kassen sker normalt ved, at kassen sænkes ned over pallen til Os højde over terræn.......hvorefter der fyldes træer i kassen. Efterhånden som kas sen fyldes med juletræer som vist i figur 6 løftes kassen op af operatøren. I dette forløb er systemet normalt udstyret med en presseanordning 30, der kan sænkes over de i kassen beroende træer og trykke disse sammen. Når kassen er i en position, hvor overkant af kasse er i niveau med overkant at d# Støtter, |ef er på pallen, bindes der snor mellem støtterne for at holde disse sammen og danne en øvre begrænsning på den pakkede palle.Packing of the box is usually done by lowering the box over the pallet to Os height over terrain ....... and then trees are filled in the box. As the box is filled with Christmas trees as shown in Figure 6, the box is lifted by the operator. In this process, the system is usually equipped with a pressing device 30 which can be lowered over the trees that are in the box and pressed together. When the box is in a position where the top of the box is level with the top of the d # Supports, | ef is on the pallet, cords are bonded between the supports to hold them together and form an upper constraint on the packed pallet.

Herefter køres løftekassen hydraulisk til top således, at bunden af løftekassen går fri af di lodrette støtter på pallen som vist i figur 6.Thereafter, the lifting box is driven hydraulically to the top so that the bottom of the lifting box is free of the vertical supports on the pallet as shown in Figure 6.

Pallen kan herefter udtages og processen kan gentages. Højden af dl kendte tårne er således givet véd kravet til, at løftøkassen skal kunne gå fri af de støtter, der er på pallen. Disse støtters højde er givet ved et ønske om at nå en maksimal højde, der svarer til højden af den pakkede palle. Højden af tårnet (4 meter) bevirker, ai de kendte pakkemaskiner har en transporthøjde på ca, 4,20 m, når de er monteret på en traktor, hvilket gør, at denne ikke lovligt kan køre på offentlig vej, hvor maksimalhøjden er 4 meter. I figur 2 er vist et tårn med fire giidestyr, 3,3',4,4', som er monteret to og to på de tø lodrette søjler 5,'5. De to nederste glidestyr 4,4 glider altid på søjlerne, mens de tø øverste glidestyr 3,1' ikke altid glider på søjlerne som forklaret i det følgende, I figur 3 er vist snittet A-A fra figur 2, og her ses det indvendige arrangement i højre søjle vist i figur 2. Normalt er højre og venstre søjle (vist i figur 2) udført éns* Som det ses i figur 3, er søjlen 5' udført med en indvendig monteret fjeder 12, som sidder mellem to indvendige glidestyr 11 og 13. Mellem fjeder-rens Vindinger er monteret en indvendig stang 10, som kan bevæges opad (i figuren) og derved bevirke en sammentrykning af fjederen 12. Når stangen 10 bevæges opad, følger overliggeren med, idet dé er gensidigt fæstet. Eiler med andre ord, når min bevæger overliggeren op, vil dette bevirke en sammentrykning af fjederen 12, hvorfor overliggeren 1, når denne ikke er påvirket af kræfter, vil ligge an mod søjlernes 5,0' øvre ender.The pallet can then be removed and the process repeated. The height of the known towers is thus given by the requirement that the lifting box must be able to disengage from the supports on the pallet. The height of these supports is given by a desire to reach a maximum height corresponding to the height of the packed pallet. The height of the tower (4 meters) causes, in the known packing machines, a transport height of about 4.20 m when mounted on a tractor, which means that it can not legally drive on public roads where the maximum height is 4 meters . Figure 2 shows a tower with four guiding guides, 3,3 ', 4,4', which are mounted two and two on the thick vertical columns 5, 5. The two lower slides 4,4 always slide on the columns, while the thaws upper slides 3,1 'do not always slide on the columns as explained below. In figure 3 the section AA from figure 2 is shown, and here the internal arrangement in right column shown in Figure 2. Normally the right and left columns (shown in Figure 2) are made one-by-one * As seen in Figure 3, the column 5 'is made with an internally mounted spring 12, which sits between two inner slide guides 11 and 13 Between the springs of the spring cleaner is mounted an inner rod 10 which can be moved upwards (in the figure) and thereby cause a compression of the spring 12. As the rod 10 moves upwards, the overlap follows, as they are mutually fixed. In other words, when mine moves the overlap, this will cause a compression of the spring 12, so that the overlap 1, when not affected by forces, will abut the upper ends of the columns 5.0 '.

Idet vi igen går til fi|ur 4, kin man her se et arrangement 6 som forbinder de to øverste glidestyr 3,3'. Når kassen, som vist i figur % bevæges opad, vil dette arrangement ramme overliggeren 1, og herefter vil overligger 1 og glidestyr 3,3' følges ad opad således, at giidestyrene 3.3' slipper søjlerne og ikke længere glider på disse 5,5', hvorimod de nedre anlæg 4,4' fortsætter med at "styre” på søjlerne, mens overliggeren 1 bevæges opad under sammentrykning af de indre fjedre 12,12'. (Bemærk at fjederen 12' ikke er vist i nogen figur, men er fjederen i venstre søjle, som vist i figur 2 ) ilår kassen derefter bevæges ned, vi! overliggeren 1 øg arrangementet 3, 3\ I følges ad, indtil overliggeren igen tigger an mod søjlemes øvre ender. Dette skyldes i de viste eksempler, at fjedrene 12,12' er blevet trykket sammen under løftningen af kassen, og at de derfor vil trække sig sammen, når de ikke længere er påvirket af kræfter.As we go back to ﬁ gure 4, one can see here an arrangement 6 which connects the top two sliders 3.3 ′. As the box, as shown in FIG.%, Moves upwards, this arrangement will hit the overlap 1, and then overlap 1 and slide guide 3.3 'will be followed upwards so that guide guides 3.3' release the columns and no longer slide on these 5.5 ' whereas the lower abutments 4,4 'continue to "steer" on the columns while the bar 1 moves upwardly during compression of the inner springs 12,12' (Note that the spring 12 'is not shown in any figure but is the spring in the left column, as shown in Figure 2), the box is then moved down by the overlap 1 increasing the arrangement 3, 3 \ I being followed until the overlap again beggles against the upper ends of the column, this being due to the illustrated examples that the springs 12 , 12 'have been compressed during the lifting of the box and will therefore contract when they are no longer affected by forces.

In sådan udvidelses- og sammentrykningsmekanisme kan også laves pi andre måder, ieks, kan søjlerne 5,5' være forsynet med en indvendig fjedermekanisme, hvor fjedrene 5,5 trækkes, n|r kassen 2 løftes. I en meget enkel version kan søjlerne være udført med en glidemekanisme, hvor kun tyngdekraften behøves, for at overliggeren kan giide tilbage til anlæg mod selernes øvre ender.In such extension and compression mechanism can also be made in other ways, ie, the columns 5.5 'may be provided with an internal spring mechanism, whereby the springs 5.5 are pulled when the box 2 is lifted. In a very simple version, the columns can be made with a sliding mechanism where only gravity is needed, so that the bar can return to abutment towards the upper ends of the belts.
