Bag deflector.

A guide device of this type is known from DE-PS 29 24 827.

In this case, the sacks that run up against the first frame-mounted sack deflector are removed from the continuous conveyor turned by 90 degrees. However, the first bag deflector causes relatively deep, permanent ones Dents on the front of the sacks are inevitable. This can on the one hand damage the Carry sacks. On the other hand, the aforementioned sack deformation can result in a correct orientation of the At least make the bags more difficult to one another, unless there is an additional connection to the guide device arranged device is provided for smoothing the bags.

The object of the invention is now to provide a guide device as specified in the preamble of claim 1 Kind of improve so that with simple

Means and measures while maintaining the palletizing performance when aligning the bags less mechanical stress on the sacks than has previously been achievable.

The solution to this problem is characterized in that a motorized limited, held fixed to the frame adjustable actuator is provided, the travel of which is transverse to the conveying direction of the continuous conveyor is directed, furthermore its actuating speed is greater than the conveying speed of the continuous conveyor is designed, and that the actuator is assigned to the continuous conveyor such that the actuator in one end position is outside of the sack conveying path, but in the other end position in the sack conveying path protrudes and rotates the bags from their original orientation.

It is advantageous if the bags are rotated from their original orientation by approx. 30 °.

This has the advantage that now the front sides of the bags when approaching the first Sack deflector for the purpose of completely rotating the sacks no longer at right angles, but at an angle are directed towards the conveying direction, which results in the desired lower sack deformation.

Of course, the sacks could be rotated a priori by 90 ° with the actuator according to the invention, but then one would have to increase the distances between the bags fed in to allow enough time to Return the actuator to the starting position so that the subsequent sack does not runs onto the actuator that has not yet been completely returned to the starting position and thus the entire palletizing device blocked.

The result is an increase in the distance between the bags at a constant conveying speed of the continuous conveyor but on the one hand a reduction in the palletizing performance, on the other hand it cannot the conveying speed of the continuous conveyor

a certain amount cannot be increased because, among other things, this increases the susceptibility of the bags to failure.

In addition, it is advantageous if the actuator is arranged in front of the second bag deflector in the conveying direction is.

A preferred, both technically favorable in terms of production as well as an embodiment of the above-described embodiment which ensures particularly gentle treatment of the sacks The device is characterized by "that the actuator is designed as a swivel arm, the one with its one end part around a vertical, seltlieh next to the sack conveying axis arranged axis is mounted pivotable to a limited extent, furthermore the pivot arm in one end position outside of the bag conveyor with its other free end part arranged in the opposite direction to the conveying direction and is designed reversibly pivotable in the conveying direction.

In terms of the task, it is also advantageous if the motor drive is a linearly effective, Motorized actuator, in particular a working cylinder, is arranged.

Further advantageous features are disclosed in claims 5 and 6 in this regard.

For further simplification it is advantageous to when the swivel arm and the second bag deflector are arranged on a common axis that is fixed to the frame are, and preferably also the swivel arm and the second bag deflector at the same level as one another are arranged.

In addition, the swivel angle of the swivel arm should preferably be designed to be adjustable, in particular in such a way that directly or indirectly interacting with the swivel arm, fixed to the frame. halted and adjustable in their effective length stops are provided.

In addition, in order to adapt the device described above to the respective conveyor speed of the continuous conveyor, it is advantageous if the swivel speed of the swivel arm can be changed _a

An advantageous development of the subject matter described above is characterized in that the Swivel arm with its free end part in the opposite direction to the conveying direction away from the bag conveying path is designed to be directed obliquely outwardly adjustable.

This makes it possible to adjust the swivel arm to support the second, if necessary To use sack deflector.

The continuous conveyor 3 is preferably designed as a belt conveyor whose endless belt is driven by a motor 7 in the direction of arrow 8.

The upper belt strand is rotatable by means of a plurality supported rollers 9, which are directed at right angles to the conveying direction *

The use of a motor-driven roller conveyor instead of the belt conveyor is possible.

The bag deflectors 4 and 5 and the swivel arm 6 are arranged above the continuous conveyor 3 so that that the sacks 2 are detected by the sack deflectors 4 and 5 and possibly also by the swivel arm 6 can.

The sack deflector 4 is attached to the frame 10 and protrudes into the conveying path of the sacks 2 that the latter on the front of a cylindrical, vertical

arranged pin 11 of the bag deflector 4 can run and then, as can be seen from Figure 1, from Continuous conveyor 3 influenced, rotated.

For mounting the second sack deflector 5 in a manner that is fixed to the frame and the swivel arm 6 is a fixed to the frame 10 and arranged at a distance above the continuous conveyor 3 and a bridge 12 extending at right angles to the conveying direction is provided.

The bag deflector 5 and the pivot arm 6 are around a common, from the bridge 12 vertically downwards striving axis 13 pivotably mounted. For this purpose, the sack deflector 5 and the swivel arm 6 have one another bearing eyes 14 and 15 arranged in a hinge-like manner.

A crank 16 is also attached to the bag deflector 5, to which the piston rod of a hydraulic Working cylinder 17 is hinged, which in turn is hinged to the bridge 12, the hinge axes run parallel to the axis 13.

From the pivot arm strives at a distance from the axis 13 to this in the same direction from a pin 18 on which the piston rod of a hydraulic working cylinder 19 articulated on the bridge 12 is articulated. Here, too, the joint axes are directed parallel to the axis 13.

The working cylinders 17 and 19 can, as can be seen from FIGS. 1 and 2, above the bridge 12 be arranged.

Under certain circumstances, however, it is advantageous to provide the working cylinders according to FIG. 3 below the bridge 12.

FIG. 3 also shows a stop 20 fixing the starting position of the second sack deflector 5 can be seen, which has an adjustable stop screw 21 corresponding to the bag deflector 5 .

In the basic position, the swivel arm 6 and the bag deflector 5 are outside of the bag conveying path and

are arranged to run parallel to the conveying direction 8 of the bags 2.

The approximately cuboid sacks 2 are the guiding device fed lengthwise.

If this alignment of the sacks is to be maintained, the sack deflector 5, as in FIG. 1 in dashed lines Lines shown as far as pivoted into the bag conveying path that the bags 2 on the bag deflector 4 can be steered past.

If, on the other hand, the sacks 2 are to be aligned transversely from their original alignment, When passing a sack 2, the pivoting lever 6 pivots out of its basic position by approximately 30 ° inside and turns the sack into the position shown in dash-dotted lines, with the swivel speed of the pivot lever 6 is greater than the conveyor speed of the continuous conveyor 3.

The sack then runs past the sack deflector 5, which was previously adjusted to its basic position, without experiencing a change in direction, and then runs onto the sack deflector h with its inclined front side, the sack being influenced by the continuous conveyor 3 up to the transverse direction running at right angles to the conveying direction. Orientation is twisted.

The swivel arm 6 has previously been swiveled back into its basic position.

In the case of sacks 2 fed in off-center, the swivel arm 6 can extend to support the sack deflector 5 its basic position can be pivoted outwards by approx. 15 °.

The invention also includes motorized actuators for rotating the sacks, for example as to the conveying direction transversely adjustable tappets are formed.

All new individual and combination features disclosed in the description and / or drawing are considered essential to the invention.
