Description

1 63554

This invention relates to a stacking apparatus for stacking round or angular tubes or the like of a long cross-section in a fixed stack for storage, bundling or transporting them. from said table, from the supports of which the tubes or the like can be dropped by moving the supports backwards onto a horizontal, vertically raising and lowering bundling table with adjustable side supports arranged below them.

The handling of pipes or other such long pieces also involves stacking in various contexts. In connection with the manufacture, the round tubes are preferably stacked and bonded into bundles of 3-, 4- or 6-angles and, for example, rectangular tubes of bundles of square or rectangular cross-section, respectively.

In a known stacking device solution (DE-OS 2 034 190), the pipes are moved one by one into the stack at the desired location, which is often too slow in relation to the production speed of the pipes. In another known solution (DE-OS 2 708 925), a selected number of pipes are transferred in a layer to the bundle, whereby a sufficient execution speed is achieved. However, the disadvantages of the known stacking devices are that they cannot easily stack both large and small as well as rectangular pipes with the same device without installation work, which is necessary, for example, with a modern pipeline producing welded pipes.

The object of the present invention is to create an efficient and versatile pipe for both round and angular, also rectangular 2 63554 pipes and the like. suitable stacking equipment. In the stacking apparatus according to the invention, the pipes raised to the inclined assembly level are fed by a cumulative feed conveyor or by gravity to horizontal supports against the rear supports. The lowerable retainers separate the desired number of tubes or the like, which are lowered onto the receiving table by pulling the brackets under the assembly table so that their tips come to the detents. When stacking angular or rectangular pipes, the detents may in some cases be kept raised. The vertical movement of the detents and the location of them and the rear stops adjust the number of pipes to be stacked in each case. The height-adjustable stacking table, which serves as the base of the tube stack, has side supports, especially for stacking round tubes, from which the sides of the assembly table are programmed to rise when the receiving table is lowered.

By arranging a sufficiently large number of tubes on the side-by-side assembly table, stacking can take place continuously even when the production of the tubes stops momentarily, which increases the stacking capacity. Separating the number of round tubes to be stacked with drop-down stops allows for easy adjustment. The position of the rear stops and stops can be mechanically changed and programmed according to the shape of the stack and the pipe size. When moving to stack rectangular pipes after round pipes, all you need to do is adjust the side supports of the stacking table to the open position.

The features of the invention appear from the following claim 1.

The invention will be explained in more detail below with reference to the accompanying drawings, in which an embodiment of the invention is shown, without limiting the invention thereto.

Figure 1 is a schematic side view of the hardware? Figure 2 is a schematic plan view of the apparatus; 3 63554 Figure 3 shows different forms of stacking round tubes in the form of hooped bundles, Figure 4 shows the stacking of round tubes in stages and Figure 5 shows the stacking of rectangular tubes.

The embodiment shown in Figures 1 and 2 of the drawing is a stacking apparatus for stacking round tubes in a fixed bundle. The pipes come bundled along the conveyor 1. The limit switch 2 gives an impulse to the lifting conveyor 3, which lifts the pipe to the inclined assembly and transport table 4 and stops. From the inclined table 4, the round tubes roll on the supports 5 against the rear stops 7 of the adjusting device 6.

When there are enough pipes on the assembly table, stacking is started. The receiving table 9 provided with adjustable side sides 8a and 8b is raised. The lowering stops 10 of the control device 6 select a suitable number of tubes, which are dropped on the bundling table 9 by pulling the tips of the brackets 5 at the stops 10. The adjusting device comprises rear stops 7 and vertically movable stops 10, the distance between which is adjusted symmetrically with respect to the center line of the stacking table 9 according to the desired stacking width. For example, a bundle shape of the type shown in Fig. 3c is stacked step by step as shown in Fig. 4 a-f by repeating the same series of movements and gradually lowering the stacking table 9. The finished pipe stack is tied into a bundle, which is transferred to the warehouse along the roller track 11.

Figure 5 shows the stacking of rectangular tubes in steps 5a-e. When stacking, the inclined rollers 12 of the assembly and transport table 4 are lifted and the tubes are fed to the supports 5 by a conveyor 13. In some cases, depending on the quality of the tubes, the stops 10 may be up and the number of tubes to be stacked can then be adjusted - and the edge threshold 14 of the transport table prevents the pipes from moving back to the table 4. The side supports 8a, 8b turned to the open position of the bundling table 9 are not shown 63554 in Fig. 5.

The functions of the stacking apparatus according to the invention can be automatically controlled by generally known techniques.
