Description

463 870 The invention will now be explained in more detail with reference to an exemplary embodiment schematically shown in the drawing. Fig. 1 shows a device according to the invention in cross section from the side, Fig. 2 a turning magnet driven by a lever system in schematic side view in its initial position (position A), Fig. 2b the elements according to Fig. 2a after the lever system has been pivoted about 400, Fig. 2c the elements according to Fig. 2a after the lever system has been pivoted at about 800, and Fig. 2d the elements of Fig. 2a after the lever system has been pivoted at 1250 to the inverted position of the magnet (position B).

In the device shown in Fig. 1, the height-adjustable conveyor chain 11 feeds a normal layer of steel bars in its raised position. The normal layer consists of a certain number of profile bars (n profiles). These are fed transversely to a height-adjustable stop 12. When the conveyor chain 11 is lowered, the layer or group of profile bars settles in the cam strips 2 attached to the turning magnets 1. From its rest position in position A, the lever 3 then pivots about the pivot point 5a to position B. entraining the profile layer. The link arm 4 with the pivot point 5b, respectively the lever system consisting of the pivot arm 3, the link arm 4 and the bearings 5a, 5b, and the pivot bearings on the turning magnet 1 make it possible to rotate the profile layer 1800 while the pivot arm 3 performs a movement cp of only 1250 (see especially Figs. 2a to 2d). After the profile layer is placed in the cam strips of the stacking magnets 6, the turning magnets 1 are pivoted back to the position A. The turning or stacking magnets 6 are then pivoted from the position B 'to the position C, and leave the profile layer on the stacking table 14. When this is done, it now feeds the conveyor chain 11 advances the next profile layer (n-1 profiles) in an unexpected state past the lowered stop 12 to a fixed stop 13. When the chain 11 is lowered, this second layer settles in the cam strips 7 of the reciprocating stacking magnet 6. The stacking magnet 6 is then pivoted from the position B 'to the position C (cp as before = 1250), and also places this inverted layer on the Stacking Table 14. This process, which gives a stack of interlocking profiles, is repeated until a predetermined number of layers or a predetermined package thickness is reached. . The stacking table 14 and the collecting pocket 15 are lowered each time a distance corresponding to a profile thickness of a drive and chain device 16 until the desired package thickness is reached. The stacking table 14 and the collecting pocket 15 are then lowered ncd below the transport level of a roller conveyor 17, which thereby takes over the profile package. The roller conveyor 17 is designed so that it can be moved transversely relative to a fixed side wall, which makes it possible to pack the profile packages. When a profile package has been handed over, the stacking table 14 and the collection pocket 15 are raised back to the initial position to form a new profile package. i 463 870 s For profile rods that are not stacked projecting into each other, eg flat or square profiles, only the second turning or stacking magnet group 6 is used. Even when stacking symmetrical profiles, eg 1-bar, only the second stacking magnet group 6 needs to be used. while the first turning magnet group 1 is kept in its rest position A. The stop 13 must, however, for each time a layer is to be received, be set a distance dx so that the l-bars can be stacked projecting into each other.

Goods that are not to be stacked, eg round bar, are fed with the transport chain 11 in a raised position directly to the stacking table 14 and collected in the collection pocket 15.

The stacking table 14, which can be raised and lowered together with the collecting pocket 15, is suitably pivotally arranged, so that its rear end can be lowered. A structurally particularly simple solution is obtained by providing the collecting pocket 15 in the side piece 18 with holding means, for example in the form of holes stored in holes, which can support the pivotable end of the stacking table in different pivot positions. The advantage of this measure is that the inclination that the profile packages receive when stacking different angle profiles can be compensated. The slope can amount to a maximum of approximately 200. The required angular position for the stacking table 14 is calculated in advance and set before the stacking begins. Alternatively, the adjustment could be made mechanically or hydraulically during stacking or assembly of the steel bars.

The device according to the invention can be used for stacking and assembling all normally occurring profiles, ie U-, L- and T-profiles, different angular profiles, flat iron, round bar, square and hexagonal profiles, 1-bar and special profiles for sheet pile walls, etc.

The features of the invention are not limited to the exemplary embodiment shown in the drawing. For example, the pivot angle can vary depending on the width and height of the profiles, the length of the levers, etc. The exact design may be adapted to the use intended for each individual case.
