The invention relates to a device for palletizing socket pipes, flange pipes and similar products that require palletizing arranged in opposite directions.

Socket pipes, flange pipes and similar products must be stacked for storage and transport* The problem here is that these products must be stacked in such a way that the pipe sockets are arranged alternately and axially offset in any and all different patterns. This is necessary in order to avoid diagonal stacking but to achieve a compact stack.

The stacking of such products is called bundling or palletizing. This palletizing is traditionally done manually. This means that there are no devices known that can perform automatic palletizing in opposite directions.

Special inventive features of the device are characterized in claims 2 to .

The invention is therefore based on the object of providing a device which makes it possible to palletize socket pipes, flange pipes and similar products in opposite directions automatically and mechanically.

|)This object is achieved according to the invention in that the device is characterized in that it consists of a receiving unit, a lifting and swiveling unit with tilting levers arranged on a machine column and movable vertically, a pre-palletizing unit arranged vertically on the machine column and

pneumatic and/or hydraulic and/or |

Figure 1 is a plan view of the device and figure 2 is a section along the line A-B indicated in figure.

Figures 1 and 2 show the device according to the invention.

It essentially consists of a receiving unit 3, a lifting and swiveling unit I with tilting lever 5 and a pre-palletizing unit 8.

in this embodiment a socket pipe, on the receiving unit 3< The receiving unit 3 has for transporting the palletized goods

The receiver unit consists of

b belts or similar transport units

Depending on the goods to be palletized, it may also be necessary _to equip the support chute with internal conveyor units, such as rollers or belts.

A special feature of the invention is that an end position detection device 15 is arranged in the area of the support channel 7. Since during alternate palletizing the palletized goods must always be placed on the support channel in a longitudinally offset manner, ie the end position of the sleeve la a··*" of the support channel 7 must be variable, this end position detection device 15 is of great importance. It can, for example, consist of several light barriers.

Once the socket pipe 1 is in the end position on the support trough 7, the lifting and swivel unit 6 moves vertically upwards with the tilting levers. Depending on the requirements and the command level in the program, the socket pipe 1 is delivered to the pre-palletizing unit in this position or is swiveled by 180° beforehand. This is done by the rotating arrangement of the lifting and swivel unit 6. To place the socket pipe 1 in the pre-palletizing unit 8, the tilting levers 5 are swiveled into a horizontal position, the support trough 7 tilts sideways and the socket pipe 1 rolls onto the horizontal tilting levers 5. The lifting and swivel unit 6 then moves vertically with the tilting levers 5 and places the socket pipe 1 in the collecting arms 9 of the pre-palletizing unit 8.

The catch arms 9 have a slight incline so that the laid down pipes 1 can roll backwards to the pivot levers 11. These pivot levers 11 are initially vertical and form a stop for the pipes 1.

Shortly before the lifting and swivel unit 6 has reached the<* lowest position, the tilting

lever 5 is moved back into the vertical position. The process already described is then repeated, with the lifting and swiveling device 6 always placing the palletized goods alternately into the pre-palletizing device.

As soon as the pre-palletizing device 8 is filled with a complete stack layer 10, it moves vertically, the swivel levers 11 are tilted into a horizontal position and the collecting arms 9 are retracted.

Thus, the pipes 1 or the stack layer 10 are placed in the waiting final pallet 12.

The present invention provides a device that makes it possible to palletize socket pipes and similar products that require palletizing in opposite directions automatically and mechanically. To control the device, a program specially developed for this purpose is activated via a computer. The working movements of the individual elements are carried out by pneumatic and/or hydraulic and/or electrical control units.
