Description

Technical field

The technical solution relates to a crank column for the storage of goods such as sheet metal parts or bodies, one above the other or side by side on the cranks.

BACKGROUND OF THE INVENTION

Such crank columns are known in various forms and designs and are sold on the market. Crank columns are mainly used in the production of body parts in the automotive industry. The relevant body parts are taken from the press manually or by robots and are stored in the crank column for further processing and transported. The crank columns for the components to be stored are arranged at a distance such that the components are not plastically deformed during transport or storage.

Each crank column has a plurality of handles that are arranged side by side or side by side.

The first crank is in the ready position. If the stored part is placed on this handle, the handle is rotated to the working position and at the same time it is rotated by the following handle, which in this way moves to the preparation position. Such a crank column is known.

There are also horizontal crank columns that have a similar function.

A disadvantage of the prior art storage crank columns is that for all these storage columns the distance between the front edge of the crank column and the crank face is always different in the preparatory position and working position according to the particular geometric conditions. This makes it difficult to quickly and smoothly fill the crankstand, because the tolerance margin for loading goods is very limited by a small potential load area. Manual handling must pay special attention to the correct orientation and horizontal or horizontal loading when loading. vertical position of the part, otherwise there is a risk of the crank tipping in the preparatory position, thereby causing an error in the distribution of the stored goods in the warehouse. This can also occur with automatic loading of stored parts when the part of the stacker slips partially or exhibits a dimensional tolerance (eg in the case of plastic parts).

The essence of the technical solution

The aforementioned drawback of the prior art crank columns removes the crank column according to the invention for storing warehouse goods one above the other or side-by-side on cranks which are provided with a stop or abutment part for warehouse goods and are rotatably arranged in the crank column a position in the operating position, which is characterized in that the distance of the crank face from the leading edge of the crank column is as large in the crank preparation position as in the crank working position.

The crank column is preferably designed so that the crank is held by the rest position and the working position by end stops.

The crank preferably comprises a control arm provided with a bore or long holes in which the crank stop pin is mounted, on which it can be mounted with a counterweight. In addition, the handle may be provided with an additional weight attached to the stop pin.

Preferably, the handles are provided with additional weights located on adjacent handles from different sides of the handles.

The crank may be provided on its steering arm with several counterweights of different diameters, which counterweights are preferably arranged in different order on adjacent cranks.

The handles can be made of one piece of stainless steel with counterweights attached.

To prevent contact corrosion, the handles may advantageously be made of a galvanized material or a surface-treated material.

It should be pointed out that the crank column according to the present invention is designed so that it can operate without the use of springs or other resilient means, due to the mutual arrangement of the crank parts and the application of counterweights and possibly additional weights.

An essential advantage of the technical solution is that the prior art drawbacks resulting from the different spacings between the crank face and the crank column leading edge and consequently existing limitations of the tolerance zone when storing goods in the crank column, both in manual and Machine filling can lead to partition errors in the warehouse.

The idea of the technical solution can be varied in various ways and thus adapted to the needs of the user. Thus, for example, end stops can be used, which can hold the handles both in the preparation position and in the working position. By means of various counterweights and additional weights, which are held by means of a stop pin, a higher or lower load capacity can be achieved with respect to the stock goods as required. The handles themselves can be made of various metal or galvanized. Coated to prevent contact corrosion.

Overview of the drawings

The invention will now be described in more detail with reference to the accompanying drawings, in which:

FIG. 1 shows a schematic perspective view of a crank column according to the invention with cranks in various positions,

FIG. 2 is a perspective view of the embodiment of the handle of FIG. 1,

FIG. 3 is a schematic perspective view of three superimposed cranks of an alternative embodiment in the same position, and

FIG. 4 is a perspective view of another alternative embodiment of the crank.

Examples of technical solution

Giant. 1 shows a crank column comprising cranks whose faces 3 have the same distance x from the crank column leading edge 4 in the preparation position I and in the working position 2, and thus the same tolerance range.

This is achieved in that the functional crank arm is shaped such that the split angle of the preparation position and the crank respectively. The operating positions 2 of the crank lie exactly at the height of the storage axis and thus describe the crank face 3 between the preparatory position 1 of the crank and the working position 2 of the chord handle.

While the prior art crank columns need to be provided with a spring in the support arm due to their weight ratios to retract it in the body of the crank column, in the case of the crank column according to the present invention, the crank arm is extended or fitted with counterweights 12 to despite the high weight of the support arm, the handle fulfilled its function purely on the basis of gravitational force.

However, this also results in an increased weight of the counterweight 12, which can be in the form of a cylindrical counterweight 12, or the control arm can be extended or the handle can be provided with an additional weight 13. FIG. 2 shows a single crank used in the crank column of FIG. 1, which includes a counterweight 12 mounted on the stop pin 11.

As shown in FIG. 2, each crank comprises a control arm which is provided with a counterweight 12 and a stop pin 11, and a support arm intended to carry the goods to be stored.

The use of large counterweights 12 results in a relatively large distance between the individual handles. This tendency can be eliminated, for example, by widening the handle in the column body and thereby creating more space for the counterweight 12. This means that the handle then has a greater width in the region of the control arm than in the region of the support arm. A further possibility is that alternately adjacent handles are provided on each side of the control arms with additional weights 13 which are attached to the stop pins 11 so that the spacing of the handles relative to each other can be reduced again. An individual handle of this embodiment, provided with an additional weight 13, is shown in Fig. 4.

Another embodiment of the counterweight of the crank is shown in Fig. 3, where the stop pins 11 of each crank carry counterweights of different diameters, the counterweights being located alternately on adjacent cranks.

In a further solution, the locations of the stop pins that secure the counterweights to the cranks have been constructed as long holes, thus guiding the weights from the crank to the handle in different positions, thus allowing the weights to tighten tightly in the working area.

According to a further variant, the cranks were assembled in an alternating manner with different counterweight distances between the storage axis and the center of gravity of the steering arm. This also causes a very tight arrangement of handles above or next to each other.

According to a further solution, the cranks are held in the zero position or in the working position by embossed teeth oriented towards the crank body. This is a very cost-effective way to set the end positions. Another advantage of this solution is the dropping of the stop pins, which limit the freedom of movement of the handles during operation.

Preferably, the support arm and the control arm are made of one piece of stainless steel. The stop pin 11 is preferably held in the steering arm by means of two bores or long holes, depending on the function of the crank, over the crank column body. The counterweights 12 are preferably slid onto the stop pin 11 and are thus held in three dimensions without fixation by additional support means. In addition to the free bearing arrangement, the counterweight can also be screwed or riveted to the control arm. In addition to galvanized metal structures, the handles can also be made of plastic or light metal.

The crank column according to the present invention enables the reliable storage of the stock goods on the supporting arms of the vertically arranged cranks of the vertical crank column or of the parallel cranks of the horizontal crank column continuously in the plane without the use of springs or other similar return elements for cranks. The pre-position and the end-position allow equally high tolerance in the position for storing the parts to be stored.
