Abstract

Stacker for stacking or unstacking crates 11. The stacker comprises a conveyor 10, lifting members 12 for gripping the crates 11 and raising them by a lifting height at least somewhat greater than that which corresponds to the height of the crates, and control members 13,14,15,16 for controlling the lifting members 12 so that these grip either a crate 11 on the conveyor 10 or the following crate 11, whereby either a stacking or an unstacking function is accomplished. <IMAGE>

Description

464 978 2 i patentkravets 1 kännetecknande del. 464 978 2 in the characterizing part of claim 1.

En såsom exempel vald utföringsform av en staplingsan- ordning enligt uppfinningen kommer nu att beskrivas med hänvisning till ritnignarna.An exemplary embodiment of a stacking device order according to the invention will now be described with reference to the drawings.

Fig. 1 visar synnerligen schematiskt en staplingsanord- ning enligt uppfinningen i ändvy; Fig. 2 visar staplingsanordningen enligt fig. 1 under ett första steg av en nedstaplingsoperation; Fig. 3 visar staplingsanordningen enligt fig. 1 under ett första steg av en uppstaplingsoperation.Fig. 1 shows very diagrammatically a stacking device according to the invention in end view; Fig. 2 shows the stacking device according to Fig. 1 below a first step of a stacking operation; Fig. 3 shows the stacking device according to Fig. 1 below a first step of a stacking operation.

Staplingsanordningen i fig. 1 innefattar ett med 10 generellt betecknat bärorgan, här i form av en rulltranspor- tör, för uppbärande av föremålen, t.ex. backar 11, på en förutbestämd nivå.The stacking device in Fig. 1 comprises one with 10 generally referred to as support means, here in the form of a roller conveyor dry, for carrying the objects, e.g. backs 11, on a predetermined level.

Det kommer i det följande att talas om lyftorgan, av vilka endast ett med 12 generellt betecknat lyftorgan visas på ritningen, men det torde inses, att väsentligen lika lyftorgan är anordnade pà ömse sidor om transportören 10.In the following we will talk about lifting means, by which only one lifting means generally designated by 12 is shown in the drawing, but it should be understood that substantially equal lifting means are arranged on either side of the conveyor 10.

Lyftorganet 12 är t.ex. under fjäderpâverkan rörligt mot och från backarna 11 och är vertikalt rörligt på lämp- ligt sätt, t.ex. med hjälp av hydraulcylindrar, pneumatiska cylindrar eller liknande i och för sig kända lyfthjälpmedel.The lifting member 12 is e.g. under spring influence variable towards and from the slopes 11 and is vertically movable on way, e.g. using hydraulic cylinders, pneumatic cylinders or similar lifting aids known per se.

Dylika anordningar utgör i och för sig ingen del av uppfin- ningen och torde därför icke behöva beskrivas närmare i föreliggande fall.Such devices do not in themselves form part of the invention. and should therefore not need to be described in more detail in the present case.

Under sin vertikala rörelse eller i anslutning hörtill styrs även lyftorganets horisontella rörelse i riktning mot och från backarna 11 med hjälp av en styrmekanism, innefat- tande t.ex. vertikala styrskenor 13 och 14 för en löprulle 15 och en rullens bana påverkande grind 16. Grinden 16, som är manövrerbar pà varje önskat sätt under styrning från t.ex. en dator, är anordnad att styra in rullen 15 till att löpa på antingen banan 13 eller banan 14.During its vertical movement or adjacent to it the horizontal movement of the lifting member in the direction of and from the jaws 11 by means of a steering mechanism, comprising teeth e.g. vertical guide rails 13 and 14 for a roller 15 and a path of the roller affecting gate 16. The gate 16, which is manoeuvrable in any desired manner under the control of for example a computer, is arranged to guide the roller 15 to run on either track 13 or track 14.

Om rullen 15 under sin rörelse uppåt löper upp pà grinden 16 och därefter följer banan 13 kommer lyftorganet 12 att passera den understa backen 11 i staplen och gripa närmast följande back för att lyfta denna vertikalt en lyfthöjd, som är tillräcklig för att den understa backen 3 464 978 skall kunna transporteras bort från stapelläget. I detta fall har staplaren en nedstaplande funktion.If the roller 15 during its upward movement runs up on gate 16 and then follows the path 13 comes the lifting means 12 to pass the lowest hill 11 in the stack and grip next following hill to lift this vertical one lifting height, which is sufficient for the lower slope 3 464 978 must be able to be transported away from the stacking position. In this In this case, the stacker has a stacking function.

Om rullen 15 däremot under sin rörelse uppåt följer banan 15 och icke pâverkas av grinden 16 kommer lyftorganet 12 att gripa den understa backen 11 i stapeln och lyfta denna samt naturligtvis hela stapeln vertikalt en lyfthöjd, som är tillräcklig för att insläppa en tillförd back under stapeln. När därefter den gripna backen och naturligtvis hela stapeln ovanför denna åter förs nedåt kommer de att vila pà den tillförda backen 11. I detta fall har staplaren en uppstaplande funktion.If, on the other hand, the roller 15 during its upward movement follows the path 15 and is not affected by the gate 16 comes the lifting means 12 to grip the lowest jaw 11 in the stack and lift this and of course the whole pile vertically a lifting height, which is sufficient to allow a supplied back under stack. When then the arrested hill and of course the whole pile above this is again brought downwards they will rest on the supplied slope 11. In this case, the stacker a stacking function.

Staplingsanordningen kan kompletteras med en utrust- ning, som vrider backarna 11 ett kvarts eller ett halvt varv, varigenom hantering även av s.k. "nestade" backar tillåts.The stacking device can be supplemented with an equipment which turns the jaws 11 a quarter or a half shipyards, whereby handling also of so-called "nestade" backs allowed.

Ett antal modifikationer och detaljändringar kan före- tas inom ramen för uppfinningstanken. ----ooo0ooo----A number of modifications and detailed changes may occur. taken within the scope of the inventive concept. ---- ooo0ooo ----

Claims

464 978 4 Patent claims

l. Stacking device for stacking objects, one on top of the other in one such as e.g. transport jaws, vertical stack, resp. for removing objects from a vertical stack thereof, comprising support means (10) for movably supporting the objects (II) in a path at a predetermined level, lifting means (12) arranged to grip the objects from either side of said path, and lifting the objects a lifting height at least slightly exceeding the respective object height and thereby either leaving a space below the lifted object or a stack thereof to allow the addition of another object to the stack, this being added from below, or allowing removal of the bottom the object in the stack, the height of which is reduced from below, and guide means (13, 14, 15, 16) for the lifting means, characterized in that the guide means (13, 14, 15, 16) are arranged to guide the lifting means (12) so that these as desired, after the corresponding shorter vertical movement, for each occasion the lowest object engages in a vertical stack to lift the stack as a whole, or in a corresponding manner, after a corresponding longer vertical movement, it grips the second lowest object in a stack for each occasion to lift the stack while simultaneously releasing the lowest object in the stack for removal from the stacker, after which the control means control the lifting means to release the temporarily gripped object again, so that it can is lowered on the support means, and that the guide means (16) are adjustable while the stacking device is in operation, so that the same functions either as a stacker or a stacker.

Stacking device according to Claim 1, characterized in that it is designed as a unit which is closed in itself, its preferably movable support members for the objects being without a fixed connection to connecting input and output conveyors. --- ooo0ooo ---
