Self-leveling ^ device for stacking objects

The invention relates to a self-leveling device for stacking objects. Devices of this type are used in particular for stacking and preheating plates and are for example from GB-PSs 1 119 686, 946 227 and 1 239 616 known.

The object of the invention is to simplify the production, the structure and adjustability of the device.

According to the invention, the device comprises »

self-aligning device with a base, a series of vertical guide elements, which are attached with their lower ends to the base around its periphery at intervals " one fixed hanging attached to the upper ends of the guide members, one vertical movable ring that converts the guide elements into one surrounding some distance under the fixed ring, a series of coil springs, which are called circular Series arranged outside the guide elements * and with their upper ends are attached to the fixed ring and their lower ends to the movable ring, a platform for supporting the articles; and a spacer supported by the movable ring and supports the platform approximately in the plane of the fixed ring.

The invention is described below by way of example with reference to the drawing. The drawing shows in:

Fig. 1 is a partially sectioned view of the device according to the invention;

FIG. 2 shows a plan view of the device according to FIG. 1; and

Figures 3 to 7 show details of parts of the device according to FIG. 1.

The device comprises a frame structure made of a circular base plate 9 »vertical uprights or Guide elements 10 and an upper fixed Hing 12. The guide elements 10 have the shape of a narrow arcuate plate to guide inner concave surfaces

11 to be provided, which have the same diameter like the base plate 9 and are welded to this.

On the underside of the ring 12, lugs 14 are arranged, to which a downwardly directed flange 15 is welded on. Each approach (see Pig. 3) contributes an upright threaded tenon 16, which protrudes through a hole in the plate 12. Nuts 17 are on the pin 16 and down to the Ring 12 screwed in order to press the puddle 15 onto the ring 12. The Plansch 15 has a series of holes to releasably receive the upper ends of a circular series of vertical coil springs 19 which is arranged outside the elements 10 »The lower ends of these springs releasably engage in a series of Holes in a vertically movable ring 20 surrounding the elements 10.

A platform 18 supports a stack of panels or other articles and a spacer is provided, in order to support the platform 18 approximately in the plane of the ring 12. This spacer consists of Cross bars in the form of a frame 21 and a support device 22 which rests on the cross bars and which Platform 18 supports. The cross bars 21 have overhanging ends 24 to rest on the ring 20 and have slots 25, in which the support device 22 sits.

The support device 22 is formed from a cruciform planar arrangement of vertical plates and the outer edges of each arm of the device 22 are supported two anti-friction rollers 27, one below the other. These rollers act on the inner curved guide surfaces of the guide elements 10.

309821 / 034A

According to an alternative, the support device can
be tubular.

The device can be enclosed in an outer container. If desired, a
Heating device are provided.

The springs can be arranged in such a way that three, four or six springs in the same V / inkelabs t η
can be used. Springs with different values can also be used, for example with 20 g / mm elongation and 15 g / mm elongation, so that densely graduated settings can be achieved.
