Self-leveling device for stacking objects

The invention "relates to a self-leveling device ?; \ M Stapolli you Gegenstäurten. Devices of this type are used in particular for stacking and preheating plates and are" known from GB-PS-946 227, for example.

It is often necessary to provide two of these devices next to one another in one housing, 3.B. for two stacks of plates of different sizes. This is usually done by providing two koripletten devices according to GP-PS 946 227 »complete with the outer tubes in the housing. This eats jodooh e + what Teär and not allowing easy V. ^r? .Rne- transfer to the plates when dins is required.

In accordance with the present invention, an apparatus includes for stacked items that nivel1ie- ^ r themselves

a frame with a base, a

upper horizontal frame with a cross member in the duct between its two ends and uprights which support the frame on the base; vertical guide means on each side of the frame midway between its ends, creating four vertical guide surfaces parallel and spaced apart from one another; two vertical carriages, each of which has anti-friction elements at its corners that engage two of the guide surfaces on each side of the frame; two rows of vertical coil springs which are arranged laterally across the frame and are connected with their upper ends to the cross member and the lower ends of which are attached to the respective carriage, wherein the guide device and the carriage are arranged between the springs and a support device for articles from the carriages carried i ^s $ and EXTEND in opposite directions by them. and vertical guide posts for guiding the articles are adjacent to the support means.

The invention is exemplified below using an exemplary embodiment on the basis of the drawing described; this shows in:

Pig. 1 is a view of a self., Leveling device according to the invention;

Pig. Figure 2 is an end view of the apparatus of Pig «1;

Pig. 3 shows a plan view of the device according to Pig. 1 with some upper parts removed;

Pig. 4, 5 and 6 are top and end views, respectively, and a side view of a portion of one the vertically movable carriage and support means to be described; and

Pig. 7 is a perspective view of one to be described upper frame.

The device comprises a box-like frame structure 10, which can be arranged in any suitable housing (not shown).

The frame structure consists of a base 11, an upper one fixed horizontal frame 12 and two pairs of vertical channel-shaped guides 13, 14 and 15, 16.

The frame 12 has two longitudinal walls 17, 18 (Pig. 7), the are connected to one another at their ends by cross struts 19, 20. In the middle between the ends of the long walls is a cross strut 22 in the form of a plate with downwardly directed edges 23, 24, each with a series of holes 25 (Pig. 7) are provided.

The guides 13, 14 are welded to the base 11 and by angle 27 and screws 28 on the cross strut 22 attached.

Each of the guides 13, 14 has its legs 30, .31 at right angles ζην base 32 and the inner surface of the legs 30, 31 serve as vertical guide surfaces z. B. each pair of guides creates four vertical spaced apart vertical guide surfaces.

The guides 13, 15 guide a vertically movable carriage 34 and the guides 14, 16 guide one vertically movable carriage 35. The carriage 34, 35 Bind identical table and only one is with particular reference to FIGS. 4, 5 and 6 are described.

The carriage consists of a vertical plate 37 (Fig. 5 and 6), the upper edge of which is bent over to form a horizontal flange 38 and the lower edge of which is in the flange 38 is bent in the opposite direction to form a horizontal flange 40 with an upturned vertical Form flange 41. The flange 41 is provided with a series of holes 42 and with the flange 23 vertical aligned. The plate 37 carries side walls 43, 44 with flanges 46, 47 and 48, 49 on their upper and lower ones End up. The side walls support upper and lower anti-friction elements in the form of rollers 51 »52, 53» 54 »which run on the guide surfaces of the guides 13» 14, 15 »16. In each guide, two rollers run on opposite guide surfaces. The roles are for this purpose offset to each other.

Two cantilever beams 57, 58 are welded to the plate 37 and can carry stacked articles.

A series of vertical coil springs 60 releasably grip with their upper ends into the holes 25 and with their lower ends releasably into the holes 42. The corresponding

309821/0343

The row of springs is shown at 61.

The stacks of articles are vertical each by four Guide rods or hill 63 out, the lower Ends are welded to the base 11 and the upper ends of which have screwed-in threads aayjf en 64.

A cover plate 65 is arranged on the frame 12 and has holes through which the threaded pins 64 protrude. Nuts 66 are screwed onto the threaded pin 64 and clamp the cover plate 65 to the frame 1.2.

The cantilever beams 57, 58 serve as independent floating ones Platforms on which the articles can be stacked directly or, if desired, a loose plate or a The tray can be placed on the cantilever beams to accommodate the Article to wear. Due to the angled cantilever construction, items can be round, rectangular or other shape can be stacked.

The number of effective springs can thus be easily changed. The springs can also be different Have voltage values, e.g. For example, some may have 20 g / mm stretch and others 15 g / mm to create a tight range of variation.

A large number of such devices can be manufactured and stacked ready for use, except: that the guide rods 63 are not attached and the corresponding holes are not drilled in the cover plate. The rods 63 can be attached to the base and the holes can be drilled for any particular size, depending on Number of devices ordered by the purchaser. This makes production easier and cheaper.
