Sack pile bridge

The present *: invention relates to a sack stacking bridge for in particular high stacks of bagged goods / such as a longitudinally movable portal bridge, with a trolley that can be moved transversely and one in the longitudinal direction arranged liftable and lowerable belt boom as well as a conveyor belt housed in this.

There are already horizontally movable bridges with a lifting and lowering belt boom for stacking and unstacking sacks, intended especially for relatively low stacking heights. The stacking area, corresponding to the work area or the pivoting area of the band boom would entail a great loss of space. Difficulties with the actual handover or takeover of seeds from the pile could not be avoided here.

The invention is based on the object / the Ein and Aus-Speiöhern of bagged goods in or out of the stack to be significantly improved and largely mechanized and, on the one hand, eifi'en ielatively high and voluminous stacking area of the goods, on the other hand, to provide a less complex * robust construction with only little space requirement * Furthermore, it is the aim of the Invention / stacking and unstacking is particularly difficult Sacks, for example with bulk goods of 100 kg weight / to mechanize *

This object is achieved according to the invention / that on outer end of the band boom comprising a downwardly facing semicircular clamping bands connected in series the bagged goods guide serving reversal as well as an articulated on this, automatically raised and lowered downstream Conveyor belt with a movably provided sack-depositing table as well as a stationary, automatically actuated one Gripping tongs for bag removal is arranged, the belt boom with the reversal and the conveyor belt, the storage table and the gripping tongs are designed to be vertically pivotable into a respectively provided position or working position.

In a variant of the invention, the sack stacking bridge is designed to be longitudinally displaceable.

Appropriately, a working cylinder mounted on the band boom is provided for actuating the gripping tongs.

In a further variant of the invention, it has proven to be advantageous that the sack storage table and the automatically actuated gripping tongs for the removal of the sack a movably mounted one attached to the frame of the conveyor belt is assigned always provided in the horizontal position control platform.

Further, it may be advisable that _f is formed in addition to the band bracket also the inversion as well as the downstream conveyor belt automatically pivotable.

On a horizontal portal bridge 1 the side along the Bag stack is movable, a movably mounted trolley 2 is arranged along the bridge 1. The transversely movable one Cat 2 is provided with a laterally designed in the longitudinal direction raisable and lowerable tape boom 3, the articulated is stored in the cat 2. In the belt boom 3, a conveyor belt 4 is provided in the longitudinal direction. At the far end of the Band boom 3 is attached a downwardly facing semicircular reversal 5, which comprises a plurality of clamping bands 6. At the The lower end of the reversal 5 is a downstream, articulated, automatically raised and lowered conveyor belt 7 arranged. The conveyor belt 7 is shifted with the clamping belts 6 or the reversal 5 concentrically on the belt boom 3, which is designed to be vertically pivotable. In addition, there is the reversal 5 as well as the downstream conveyor belt 7 arranged automatically pivotable. At the end of the conveyor belt 7 there is an axially movable bag storage table 8, which comprises two halves which can be pivoted downwards when the sack is discharged and which is always held in a horizontal position.

To pick up the sack there is a 7 on the superstructure of the conveyor belt The working cylinder 9 is arranged with a stationary, automatically actuated gripping tong 10.

The Öireif Sänge 1Ö, which can be actuated by the working cylinder 9, is designed with 2WeI pincer clamps that pick up the Saökgut in atfbeitspöäitlört and transfer it to the conveyor belt 1 .

'The working method is as follows '.

When the bags are stacked, the entire conveyor belt 3 in the respective vertical Arbeitsspösitiön pivoted, wherein The sacks are brought into the storage position via the conveyor belt 7 and the sack-depositing table 8 With successive stacking, the conveyor belt 7 is lifted after each storage and a further sack is stacked in the stack.

When stacking, the belt delivery 3 is moved with the conveyor belt 7 into a corresponding, for example, upper position, into which the respective sack is brought onto the conveyor belt 7 via the gripping tongs 10.

The bagged goods are transported via the clamping belts 6 in reverse 5 to the downstream conveyor belt 7 or the other way around, guided.

When the conveyor belt 7 is pivoted downwards, the reversal 5 is used to guide the Sa-kgutes in the axis of the conveyor belt. casual 3 shifted so that the circular configuration of the clamping bands 6 dissolves into a straight line.

The sack stacking bridge according to the invention can be used, for example, when loading and unloading ships, with sack piling in the ship's hatches.
