Device for stacking or destacking stacking units

The invention relates to a device for stacking or unstacking stacks units _£ B z _s bottle crate, box or the like ,, with the stacking units to a certain extent lifting or lowering the lifting device and with engageable and disengageable jaw, the raised pile hold at a certain support height

In the known stacking or unstacking devices of this type, the clamping jaws can only be moved back and forth in the direction perpendicular to the stacking units held stack presses · Once the jaws are disengaged _for the stack of the lifting device even under catch "a disengagement of the jaws before reaching the stack base by a new stacking unit had a falling down of the stack, a later release of the jaws blocking the lifting consequence" There the disengagement point of the clamping jaws can only ever be assigned to a specific stroke of the lifting device, the known devices can only be used for stacking or unstacking stacking units of the same height. If less high stack units were to be stacked, the stack slipped downwards at the moment the clamping jaws were opened «. In the case of stacking units that are higher than normal, however, the upper edge of the new stacking unit to be lifted would hit the stack from below at a point in time at which the clamping jaws have not yet disengaged.

The purpose of the invention is to train a device of the type defined at the outset in such a way that it can be used as a

mixed stacking or unstacking of stacking units different heights are suitable * This is achieved according to the invention in that - the clamping jaws in such a way are stored * that they are in the engaged position upwards sii are movable and in the disengaged state in the Return support height »

In the inventive device, the time of disengagement of the KlemmbacliOu is pressed associated with such lifting path of the lifting device _f that retraction of Klemmbaofesn earliest effected when a stacking unit underside _n with the lowest -vorkommenden height by the lifting device as the U of the raised stack * If stacking units with a greater height are now raised, then touch., these ■ the underside of the raised. Stack already at a point in time at which the clamping jaws are still indented. However, this does not su blocking of the lifting device _s since the indented Klemmbacknen after könnenc to be enough above the disengaged jaws return ^ matter ^ how far they turned up> to support alarm level back and hold the stack in the verge · = - ■ stipulated height * '■

Embodiments of the invention are in the drawing shown. Show it!

Fig. 1 is a schematic view of a device for stacking or unstacking stack units according to the invention;

2 to 5 different embodiments of the

Storage of the jaws of the instrument of FIG _e 1 _f wherein each in the left half of the clamping jaws in the support alarm level and in the right half according to the move upwards shown are _e

In the drawing, 1 is a schematically indicated frame of a stacking device according to the invention Stacking device, for example, boxes should be stacked in a columnar shape ^ Let it be for the sake of simplicity for the sake of assuming, that there are only two types of crates, namely boxes 2a with a height a and boxes 2b with a smaller height b. With the device, however, could Even more types of boxes with different heights can be stacked * The boxes are shown in the drawing indicated by dash-dotted lines

A lifting device with a constant stroke H 'is provided for lifting the crates entering the device on a conveyor track (a * B _o a roller track, not shown). The design of this lifting device is not important for the "invention". The lifting device is, however, well sbenso cross under the crate bottoms mechanically ^ hydraulically or pneumatically actuated lift cam be provided in the drawn embodiment of a hydraulically driven lift 3 _O Eqfeönnten _s

At a certain height - hereinafter referred to as Support height S should be referred to as »above the inlet level, Elermnbaoken 4 which can be engaged and disengaged arranged, which hold the already raised stack of crates in the engaged state mounted on frame 1

When the stack is formed, the clamping jaws 4 may release the raised stack at the earliest when the upper edge of the crate called up by the lifting device 3 is in contact with the bottom of the crate that was raised immediately before Release by the clamping jaws of the following box, or supported by the lifting device 3 and does not rush down *, This means that when stacking boxes of different heights, the clamping jaws 4 may only be withdrawn when the lifting device 3 lifts this type of _& at de © abuts the upper edge of the smallest occurring boxes (2b) aa bottom of the stack * In the geζeiohneten embodiment, the clamping jaws 4 would thus control so su _t that they disengage when the lifting device 3, a stroke H ^ b go through HA ^ if but now larger boxes (2a ^ are lifted, then they hit the bottom of the stack earlier "namely after a lifting path H" a _f

so that when the stack is held in place, the lifting device tion would be blocked,

According to the invention, this difficulty is circumvented in that the clamping jaws 4 are in the engaged state be able to move upwards and return to the support height S in the disengaged state. «The work cycle is then the following:

Assuming that a lifted crate been run in the device and the already raised stack is held in the support height S by the jaws 4 _s IDRD first the lifting device set in motion 3 * The jaws 4 are made of in FIG, drawn clamping position 1 earliest then withdrawn when the lifting device has reached stroke H - h . If the lifted box of the kind with the lowest height b _§ then takes -to this time * The retracted jaws 4 remain straight support of the stack ,, which is raised b in the further upward movement of the lifting device by the dimension thereby are _A is the Stroke H is completed, then the KLewmbacfcea are re-engaged and hold the enlarged stack firmly at support height S. The empty lifting device returns to its starting position,

If the crate to be lifted is of a height greater than the minimum height b, for example height a, then the upper edge of the box lies down before retracting the

Clamping jaws 4 already on the underside of the stack at ₃ The stack is lifted together with the engaged clamping jaws * In this case, too, the clamping jaws are disengaged as soon as the lifting device reaches the lifting path H ■ - b . The disengaged clamping jaws 4 move to the support height S gurückj which can be done due to their own weight or with the help of spring force, and clamp the raised stack in the support height S _f soJ) ald the stroke H is completed *

The retraction of the jaws 4 must only at the earliest on reaching the stroke II "h" done * The jaws may also be dissolved later ₉ in which case they also when lifting a box with the smallest height perform an evasive movement upwards, which is however less than in the cone ₉ as the evasive movement in the case of a higher crate to be lifted _β

In FIGS. 2 to 5 different possibilities are shown how the clamping jaws can be deflected upwards can be stored

In the embodiment according to FIG. ₀ , 2, the hydraulic piston-cylinder units 5 are firmly mounted on the frame 1. The piston rod 6 of the unit can therefore only be moved horizontally _c The clamping jaws 4 are iron handlebars 7, which at 8 are articulated with the piston rod are connected _o The clamping jaws 4 can itself be hinged to the handlebars 7 or provided with such a profile * that they pivot upwards when pivoting

roll on the side walls of the box «. When the jaws müssenj as shown in Figure ₀ 2 to the right, move upwards then the link pivoting about the hinge point 8 on top * piston rods 6 have extensions 6a, the movement of the arm 7 downward such begrensen * that of The handlebars returning to the swiveled-out position are held at the support height S

Instead of the actuators of the jaws with these su connected by upward swing-out arm, and the actuators themselves can be pivotally mounted on the frame 1 "This possibility is shown in Fig. 3 * Here are the clamping jaws 4 directly to the piston rods 6 of hydraulic piston 2ylinder unit mounted fixed or hinged, and the cylinders 5a of the units are visible in 9 about horizontal pivot pin pivotally hinged to the frame 1. As shown in FIG _o 5 to the right, can dieiKlemmbacken 4 then dodge by a pivoting movement of the piston-cylinder units 5 upward " In order to limit the return of the clamping jaws 4 downwards in the support height S su, stops 10 are provided on the frame 1 on which the piston-cylinder units 5 rest ^ Of course, a kinematic reversal would also be possible here in such a way that the clamping jaws with connected to the cylinders and the piston

rods 6 hinged to the frame 1 sincL

In the embodiment according to FIG. 4, the clamping jaws are formed by shoes 11 which can be laterally pressed against the stacking units _{2a f b by means of the hydraulic piston cylinder units 5} 12 ₈ on which the shoes 11 can slide in the stacking direction * The guides can be designed as sliding, ball or roller guides « rests on the end face of the part of the piston rod 6 forming the guide 12 as soon as the shoes 11 have returned to the support height S.

Finally, reference should be made to the possibility shown in FIG. 5 after de}? the piston-cylinder units 5 in turn connected directly to the clamping jaws 4 via the piston rods β and for this purpose on the frame 1 in Vertical guides 13 are held "which an evasion of the Allow units 5 together with the Xlemn jaws 4 upwards * The ', Veg der Eoiben »ZyiInder-Units 5 after below is again limited by stops 14 attached to the frame 1 at the support height S «,

The Ausxülmmgsformen FIGS _e 4 and 5 have the advantage that the clamping action during the Ausueiehaufrechterhalten can- be Bsi the execution

form according to FIGS. 2 and 3, however, the clamping effect is canceled very soon, which under certain circumstances may also be desirable _ffi
