Description

Uppfinnare: G Decker Uppfinningen avser en griptang som tillsatsapparat for en staplingsmaskin for stapling av styckegods, exempelvis bomullsbalar. Tillsatsapparater for staplingsmaskiner aro landa, vilka mojliggora transport av styckegods ph de mest olikartade satt. Fyrkantigt styckegods, som ej befinner sig pa underlag, sasom exempelvis pallor, kan salunda giipas med de Um& griptangerna samt darefter lyftas eller sailkas, varefter det ater avlagges endast i det lage, i vilket det gripes. En tippning av det fyrkantiga styckegodset kan vid anvandning av de kh.nda anordningarna endast ske med hjalp av extra arbetsliraft. Inventor: G Decker The invention relates to a gripping pliers as an attachment apparatus for a stacking machine for stacking piece goods, for example cotton bales. Attachments for stacking machines aro landa, which make it possible to transport piece goods ph the most diverse set. Square piece goods which are not on a surface, such as pallets, can thus be seized with the Um & gripper tongs and then lifted or sailed, after which it is again deposited only in the layer in which it is gripped. When the kh.nda devices are used, a tipping of the square piece goods can only take place with the aid of extra working gear.

Vidare aro tillsatsapparater for staplingsmaskiner kanda, vilka med griptanger svanga det gripna styckegodset endast oinkring en parallellt med korriktningen liggande vridningsaxel. Furthermore, attachment devices for stacking machines are known, which with gripping pliers pivot the gripped piece goods only around an axis of rotation lying parallel to the correction.

Uppfinningen har till andamal att astadkomma, att fyrkantigt styckegods, exempelvis bomullsbalar, utan insattning av extra arbetskraft med hjalp av en pa staplingsrnaskinen anordnad griptang kan tippas fran horisontellt lage till vertikalt och omvant. Enligt uppfinningen uppnas detta darigenom, att griptangens hada armar eller kaftar Oro utformade i tva delar, varvid de inre armarna aro fritt svangbart forbundna med de yttre armarna. De inre armarna, som I ett utgangslage aro parallella med de yttre •armarna, aro svangbara med hjalp av segment, som arc lagrade i de yttre armarna samt anordnade att svangas fram och tillbaka p. hydraulisk vag. The object of the invention is to provide that square piece goods, for example cotton bales, without the use of extra labor with the aid of a gripping force arranged on the stacking machine can be tipped from a horizontal position to a vertical and vice versa. According to the invention, this is achieved in that the gripping forceps' had arms or shafts are formed in two parts, the inner arms being freely pivotally connected to the outer arms. The inner arms, which in an initial position are parallel to the outer arms, are pivotable with the aid of segments, which arc are stored in the outer arms and arranged to be swung back and forth on a hydraulic shaft.

Anordningen enligt uppfinningen f8rklaras narmare i det foljande under hanvisning till bifogade ritningar, som visa en utforingsform. Fig. 1 visar darvid en sidovy av en staplingsmaskin .med de inre armarna i olika installningslagen. Fig. 2 visar staplingsmaskinen sedd ovanifran med gripkaftarnas armar utgangslaget. Fig. 3 visar en skarning Mugs linjen A—B i fig. 4 genom en yttre arm med det i denna anordnade segmentet. Fig. 4 visar en skarning langs linjen C—D i fig. 3 genom en inre och en yttre tangkaftarm. The device according to the invention is explained in more detail in the following with reference to the accompanying drawings, which show an embodiment. Fig. 1 then shows a side view of a stacking machine with the inner arms in different installation layers. Fig. 2 shows the stacking machine seen from above with the arms of the gripping shafts the starting layer. Fig. 3 shows a cut Mugs line A — B in Fig. 4 through an outer arm with the segment arranged therein. Fig. 4 shows a cut along the line C — D in Fig. 3 through an inner and an outer pliers arm.

'Staplingsmaskinens 2 lyftpelare 1 uppbar en griptang 3, som bestar av yttre armar 4, 5 jamte inre armar 6, 7, vilka erhalla sin rorelse fran segment 8, som aro anbragta i de yttre armarna 4, 5 saint svangbara fram och tillbaka ph hydraulisk vag. I det i fig. 1 visade utgangslaget for gripthngen 3 aro de inre armarna 6, 7 parallella med de yttre armarna 4, 5. Styckegodsel, exempelvis homullsbalar, gripes darvid i horisontellt lage samt lyftes eller sankes i beroende av hojden ph den plats, dar godset gripits. Genom en ledning 9 till-fares olja eller annan lamplig vatska, som genom oppningen 10 inkommer i pilens 11 riktning i halrummet 12 for att utova tryck mot segmentet 8. Harvid vrides segmentet 8, varvid samtidigt de med segmenten genom en forbindning 22 forbundna inre armarna 6, 7 utfora en motsvarande svangningsrorelse, sa att det gripna styckegodset svanges till vertikalt lage. Dd griptangen 3 avlagt styckegodset och frigivit detsamma med sina yttre och inre armar 4, 5 resp. 6, 7, tillbakaslappes den i halrummet 12 och i tillforselledningen 9 befint,liga vatskan. Segmentet 8 och darmed de inre .armarna 6, 7 atervanda till utgangslaget darigenom, att vatska genom en. ledning 13 och en inloppsoppning 14 tillfOres i pilens 15 riktning till halrummet 16. DA de inre armarna 6, 7 atervant till sitt med de yttre armarna 4, 5 parallella lage, avlastas vatsketrycket i halrummet 16 och tillforselledningen 13. Staplingsmaskinens 2 griptang 3 hr darmed pa nytt redo att mottaga ett fyrkantigt styckegods, som skall tippas en vinkel 90° fran det lage, i.vilket .det befinner sig. 2— — Mellan de yttre armarna 4, 5 och de inre armarna 6, 7 aro rullager 17, 18 anordnade. For att forhindra vatskans uttrangning melIan segmentet 8 och halrummen 12, 16 aro tatningar 19 anordnade. En andiageskontakt 20 kan vara anordnad att begransa de inre armamas svangning till vertikalt Ege, och en annan andlageskontakt 21 kan begransa svangningen till horisontellt Ege. The lifting column 1 of the stacking machine 2 carried a gripping pliers 3, which consist of outer arms 4, 5 as well as inner arms 6, 7, which receive their movement from segment 8, which are arranged in the outer arms 4, 5 saint pivotable back and forth ph hydraulic vague. In the starting layer for the gripping hinge 3 shown in Fig. 1, the inner arms 6, 7 are parallel to the outer arms 4, 5. Piece goods, for example gum bales, are thereby gripped in a horizontal position and lifted or lowered depending on the height of the place where the estate was seized. Oil or other suitable liquid is supplied through a line 9, which enters through the opening 10 in the direction of the arrow 11 in the cavity 12 to exert pressure against the segment 8. The segment 8 is then rotated, at the same time the inner arms connected to the segments through a connection 22 6, 7 perform a corresponding oscillating movement, so that the gripped piece goods are pivoted to a vertical position. The gripper pliers 3 laid down the piece goods and released the same with their outer and inner arms 4, 5 resp. 6, 7, the liquid present in the hall space 12 and in the supply line 9 is folded back. The segment 8 and thus the inner arms 6, 7 return to the starting layer thereby, to wade through a. line 13 and an inlet opening 14 are supplied in the direction of the arrow 15 to the cavity 16. When the inner arms 6, 7 are atop parallel to the position parallel to the outer arms 4, 5, the liquid pressure in the cavity 16 and the supply line 13 are relieved. again ready to receive a square piece of goods, which is to be tilted at an angle of 90 ° from the layer in which it is located. 2— - Roller bearings 17, 18 are arranged between the outer arms 4, 5 and the inner arms 6, 7. To prevent the liquid from squeezing out between the segment 8 and the cavities 12, 16, seals 19 are provided. An andage contact 20 may be arranged to limit the oscillation of the inner arms to vertical Ege, and another and contact contact 21 may limit the oscillation to horizontal Ege.
