Thus, the loosely piled bag 2 is arranged easily in a narrow passage.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is an apparatus for taking out bags, etc. from a storage area and transporting them to a processing site, for example, a place where the bags are captured by a filling device,
The apparatus includes one bag removal means, which is equipped with a conveyance means for transporting the removed bag to a predetermined location, in which case the width of the storage area is much larger than the width of the bag. , wherein said storage area is adapted to hold a pile of bags laterally offset from each other.

[Prior Art and Problems Therewith] Most currently known bag removal devices have one storage area, the width of which is approximately equal to the width of the bags stacked with their edges aligned. The bag taken out from this storage area moves forward in a straight line,
There is nothing to guide the sides of the bag as it is sent to a predetermined processing or shipping station, where there are virtually no lateral forces on the bag.

The disadvantage of such a transport line is that the bags always have double folds on both sides, and the sides of the bags placed in the storage area are significantly higher than their central parts. Occur. This not only requires extra space in the storage area, but also causes various problems in handling and removing bags from the storage area.

German Patent No. 2,549,284 discloses a device as described above, in which the storage space has a width wider than the width of the bag,
This allows the stacks of bags to be staggered from each other and stacked in the storage area. In this known device, the removal of the bag is carried out by means of a suction lifter, which has a suction head capable of controlling the pressure of the suction tube, by means of which the uppermost bag is suctioned. The suction lifter is movable from a horizontal plane to a vertical plane, thereby bringing the suction head to atmospheric pressure and releasing it from the bag. The bags are then conveyed from there by further conveying means to their final position, and from there they are advanced to the next filling station.

A disadvantage of the known device is therefore that its deployment is very complex.

Means for Solving the Problems and Their Effects The first object of the invention is to remedy the drawbacks of this device and to provide a device that is characterized by simple deployment and procedure.

The invention is characterized in that a stop is placed after said removal device, said stop contacts at least one long side of said bag, and a top stopper is provided for transporting said bag. the stop is movable orthogonally to the direction of transport, said stop cooperating with a further stop brought into contact with said bag, and said further stop being provided parallel to the direction of conveyance of said bag. It is also characterized in that it can be formed by two fingers placed at a distance in the transport direction of the bag, by means of which the bag is transported to the next location.

By doing this, you can simply transport the bag and then
It is possible to stack the bags offset from one another at another location, from where they can be easily advanced to the next filling station. In practice, using a wide storage space and without making any changes to the processing and shipping area, by using the above-mentioned movable stops, all products can be placed in the same place with a certain lateral distance from a given fixed point. can carry bags of

Furthermore, if existing equipment is used, where the width of the storage area is the same as the width of the bags to be loaded, and the bags are removed and transported to the shipping table, the present invention allows it to be re-equipped, in which case the width of the storage area can be increased. , just attach a stopper to the shipping table.

A further feature of the invention is that the two stops are provided movably at right angles to the transport direction of the bag.

This makes it possible to have a very narrow side passageway for moving the bags, which can also be adjusted at any time.

In one preferred embodiment of the invention, the stops are each formed by a pair of fingers, the top of which passes from below through an elongated hole in the support of the bag, and is pivotable. It is also eccentrically connected to the rotating disk by a connecting rod.

This simplifies the structure of the device of the invention.

In order to make the device of the invention applicable to bags of various sizes, the top is generally L-shaped, with one arm
adjustable and fixedly held by one leg;
The arm is provided to swing and is connected to the rotating disk via a connecting rod.

[Example] Bags 2 are piled up in a storage area 1, and as shown in FIG. 2, individual bags 2 or stacks of bags are placed in a horizontally shifted state.

In FIG. 2, the folds of the pleats in the side walls of the bag 2 are indicated by short dashed lines, and the edges 4 of the side-by-side offset bags are partially indicated by long dashed lines.

The height of a pile of bags 2 is kept constant by a floor 5 that can be raised and lowered, and the bags 2 on the - layer are always placed at a height close to the upper end of the storage area.

The superlattice 6 goes around the station via pulleys 11, one or a pair of which are connected to a drive. The super lattice 6 functions to carry the bag 2 in the direction of a predetermined discharge hot water 7, and this super lattice B has a lattice surface 8 in which chains on both sides are connected by lattice rods IO, and this surface is connected to the lattice rods 10. They are separated by a portion 9 where no. This portion 9 is preferably provided longer than the storage area in the transport direction of the superlattice 6.

A removal device is provided above this station, said device being formed by a suction lifter, which mainly
It consists of a keyed prostrate lever with a suction head 13 at its free end, which lever is actuated by a cylinder-piston arrangement.

A subatmospheric or atmospheric suction line (not shown) is connected to this suction head. Retrieval device 12
This control is carried out by lowering the lever with the suction head 13 between the superlattice 6 while the part 9 without the grid bars is moving under the extraction device 12.

The suction head 13 lifts the topmost bag in the storage area l and raises one end of this bag to a higher position on the superlattice 6.

The subsequent lattice surface 8 completely scoops up the bag 2, which has already been lifted at one end, as shown in FIG.
The suction head 13 is then released and the end of the bag falls onto the superlattice and is carried away by it.

A superlattice B transports this bag 2 to a forward conveying means 14, which has several rotating drive belts 15, one of which slides over the table 1B. These drive belts】
5 is intermittently driven by a drive device 17 controlled by a positioning sensor 18. In this case, this drive is interrupted after a predetermined delay time at the same time as the positioning sensor 18 detects the front end of the bag 2, and the positioning sensor provided, for example, as a photoelectric passage detector detects the position of the rear end of the bag. It is driven again as soon as it detects that it has passed.

The bag 12 thus stops in a predetermined position and is advanced by the charging device I9 towards, for example, an openable and closable filling hopper 20.

In such an arrangement, the delivery table 1B has four holes 21 provided perpendicularly to the bag transport direction,
A stop 22.22' is passed through this hole.

The stops can be moved toward each other as shown in FIG. This includes a rocking arm 23.23' which has generally L-shaped fingers 24.23' at its free end.
24' in a fixed and adjustable manner. This results in
Stops 22.22' when these are closest to each other
You can adjust the spacing to match the width of the folded bag.

A rotating disk 26 is connected to the arm 23, 23' via a rod 25, and this disk rotates alternately by a predetermined angle, and in this case, the connection point of the rod is shifted 180'' to the opposite side on this disk. It is provided.

When the front end of the bag coming from the superlattice 6 reaches the conveying means 14, from here the bag is advanced by this conveying means;
If necessary, the direction of advance is adjusted by means of the guide plate 27. In this case, the stop 22.degree. 22' is in the outermost position, so that the bag can proceed unhindered in the direction of position 7.

As soon as the bag 2 enters the area of the positioning sensor 18, the drive belt 15 stops and the bag remains in its position 7. The rotating disk 2B then rotates and the stops 22, 22' approach each other, so that the bag is brought to the center, from where it is gripped by the charging device of the openable filling hopper 20.
