Description

FIELD OF THE INVENTION

The present invention relates to a device for transporting and filling sacks, preferably open sacks, comprising a filling device rotatable about a rotation axis with a plurality of filling openings distributed over the circumference of the filling device, wherein for compacting the bulk material in the sacks beneath at least one filling opening Vibration plate is provided, which is seen from the filling opening is inclined outwards, so that filled bags rest on the vibrating plate, and to a corresponding method.

STATE OF THE ART

Various devices for transporting and filling bags are known from the prior art. Among other things, these devices are also used for filling open sacks, so-called open sacks, with bulk material. To increase the throughput of such devices are often designed rotatable, with fixing units, which serve to secure the bags around the filling openings (such as at a filler neck) or below the filling openings, are arranged rotatably about a rotary column. Empty sacks are conveyed by a feeder to the filling device and taken over by this. After attaching the bags to the filling openings by means of fixing units, the bags are filled and further transported by rotation of the filling device until they are removed from the filling device by a bag removal device again.

According to the DE 34 16 155 A1 It is known to provide a so-called side shaker for compacting the bulk material in the bags for each filler neck. This side vibrators are attached to the rotating column of the filling device and can be swung out so that the support surface of the side vibrator is inclined outwardly as seen from the filler neck, so that filled bags that are held on the filler, rest in an oblique position on the vibrating plate.

However, this device has the disadvantage that the material of the bag is still heavily stressed by the weight of the filled bag is because the vibrating plate offers little support for the bag by the only slightly oblique arrangement.

OBJECT OF THE INVENTION

It is therefore an object of the present invention to relieve the material of the filled sacks.

PRESENTATION OF THE INVENTION

According to the invention, therefore, in a device for transporting and filling sacks, preferably open sacks, comprising a filling device rotatable about a rotation axis with a plurality of filling openings distributed over the circumference of the filling device, a vibrating plate being provided for compressing the bulk material in the sacks below at least one filling opening is, seen from the filling opening is inclined outwards, so that filled bags rest on the Rüttelplatte, in an end portion of the Rüttelplatte, which is remote from the filling opening, a filling opening towards the movable support member provided to a filled, resting on the Rüttelplatte bag to support in the ground area.

In general, each filling opening is assigned its own vibrating plate, so it is provided under each filling opening a vibrating plate. The support element serves - in the state moved to the filling opening - to relieve the bag material and thereby causes a bulging of the bag, which in turn gives better filling and thus a reduction in the degree of filling.

As a support element for a filling opening towards pivotable flap is provided. By virtue of the fact that the flap is pivotable, it can be removed from the range of movement of the empty or filled bag when feeding an empty bag to the filling device and / or when removing the filled bag from the filling device, so that the feeder and / or the bag removal device are the same Can perform movements that is possible even with a vibrating plate without flap. Existing filling devices could also be retrofitted with a flap according to the invention.

In most cases, the vibrating plate is a greater length (measured parallel to the axis of rotation of the filling device) as a width (measured in the circumferential direction of the Axis of rotation of the filling device). The length is best dimensioned to achieve the best possible compression so that the attached to the filling opening or the filler bag rests up to its bottom on the vibrating plate.

The vibratory plate may be formed as a unit which forms a single continuous support surface for the bag. But the vibrating plate can also consist of several, independently stimulable units, which then form a subdivided into several individual plates support surface for the bag.

The inclination of the vibrating plate, more specifically the bearing surface of the vibrating plate, relative to the axis of rotation of the filling device is about 10-20 ° and may be e.g. 15 °. The inclination of the vibrating plate can be basically adjustable. But since a filling device is usually tuned to a particular bulk material and certain bags, and the inclination must not necessarily be adjustable, but can be fixed.

In order to avoid a disruption of the filling operation by the flap, it is provided that the flap in a folded away from the filling opening first position forms a plane with the bearing surface of the vibrating plate for the bag.

A particularly good support of the filled bag results when the flap forms a right angle with the bearing surface of the vibrating plate for the bag in a second position folded towards the filling opening.

Instead of a flap, which does not fall under the invention, the support element can be moved linearly towards the filling opening, in particular parallel to the support surface of the vibrating plate. As a result, when an empty bag is being fed to the filling device and / or when the filled bag is removed from the filling device, the support element can be removed from the area of movement of the empty or filled bag, away from the filling opening, so that the feeder and / or the bag removal device can perform the same movements that is possible even with a vibrating plate without support element. Existing filling devices could also be retrofitted with such a support element.

In addition, the linearly displaceable support element can be adjusted to different bag sizes, more precisely bag lengths. For shorter bags, the support element to support the filled bag further towards the filling opening, so up, proceed as in longer bags.

When linearly displaceable support member can be provided that the support surface of the support member includes a fixed angle, in particular a right angle, with the support surface of the vibrating plate. There are thus no pivotable parts necessary in this embodiment. However, it would be conceivable additionally to move a pivotable flap linearly or to pivot a linearly displaceable supporting element in addition to the filling opening and away from the filling opening.

The method for transporting and filling bags, preferably open-mouth bags, with a device according to the invention assumes that a feeder feeds an empty bag to a filling opening.

It is envisaged that the support member is during the feeding of the empty bag in a remote from the filling opening first position, and the support member is transferred later than in a closer to the filling opening second position when the bag has been filled. In this way it is ensured that the empty bag does not catch on the support element when plugging onto the filling opening. This also ensures that the completely filled bag is supported.

In particular, during the feeding of the empty bag, the flap can be located in a first position folded away from the filling opening, and the flap can then be transferred into a second position folded over to the filling opening at the latest when the bag has been filled. If the support member is linearly movable, the support member may be during the feeding of the empty bag in a remote from the filling opening first position, and at the latest shifted to a closer to the filling opening second position when the bag has been filled.

In order to support the bag even during filling, it can be provided that the support element is already transferred during the filling of the bag in the closer to the filling opening second position. In particular, it can be provided that the flap is already transferred during the filling of the bag in the hinged to the filling opening second position.

An embodiment of the invention provides that the support element is removed from the once reached second position again and moved in the first position, and is again transferred to the second position. In this way, a collision of the Stützelelements, in particular the flap, carried on the bottom of the filling or the already filled bag, which may also contribute to the compression of the bulk material in the bag.

In particular, it can be provided that this process is repeated several times, ie several shocks of the support element, such as the flap, carried on the bottom of the bag.

So that the process of removing the filled bag from the filling device is not disturbed by the support element, it can be provided that the support element, in particular the flap, is transferred again into the first position before the filled bag is taken off.

WAYS FOR CARRYING OUT THE INVENTION

Fig. 1 shows an overview of a device according to the invention for transporting a bag 1. The device comprises a filling device 2, the filling openings are formed by filler neck 3. Above each Filler 3 is a hopper 4 is arranged, which is acted upon by a device, not shown, with bulk material. The device further comprises a feeder, which is composed here of a holding device 5 and a pivoting device 6. Also, the device comprises a bag removal device 7 for removing a filled bag from the filling opening of the filler neck 3. Under each filling opening or under each filler neck 3 a downwardly obliquely arranged vibrating plate 8 is provided, on which the filled bags 1 rest. By shaking the vibrating plate 8, the bulk material is compacted within the bag 1. In addition, a pivotable flap 24 is provided to support a filled, resting on the vibrating plate 8 bag 1 in the bottom area.

The flap 24 is arranged at the lower end of the vibrating plate 8, namely pivotally mounted. In Fig. 1 If the flap 24 has been folded downwards, it can be located, for example, in the same plane as the contact surface of the vibrating plate 8. This flap 24 is used in the upwardly folded state, where it is, for example, approximately normal to the vibrating plate 8, at least to relieve the bag material of the filled bag 1. The flap 24 may also support the compression of the bulk material in the bag 1.

Instead of the flap 24 and a plate could be provided which is movable parallel to the vibrating plate and a fixed angle, for example 90 °, with the vibrating plate 8 includes. The plate would then be in Fig. 1 be slightly inclined upward and would be located approximately at the level of the lower edge of the flap 24. Between the plate and the vibrating plate 8 would be in this, distant from the filler neck 3 position, a distance.

The filling device 2 has a vertically arranged in the operating state rotary column 9, which is rotatable about a rotation axis 10. The filling device 2 rotates here at a constant speed counterclockwise. Of course, the filling device 2 can be moved in accordance with mirrored arrangement of the device according to the invention also in a clockwise direction. With on the filling device 2 movably mounted brackets 11, which are adapted to the shape of the filler neck 3, the bags 1 can be fixed to the filler neck 3 by clamping. The here circular disk-shaped carrier 16 of the filling device 2 carries on the one hand the hopper 4 located above the carrier 16 and the filling nozzle 3 arranged below the carrier 16. The diameter of the carrier 16 thus forms the largest diameter of the filling device 2 in this example.

Of the holding device 5 is in Fig. 1 the first holder 12, which is movably mounted on the filling device 2, largely concealed by the filler neck 3. Only the second holder 13 can be seen, which is movably mounted on a fixed space guide. The solid guide 14 is formed here as a curved guide rail, and is spatially fixed in the sense that it is not attached to the filling device 2 and thus not co-rotated with the filling device 2. The guide 14 may for example be attached to a housing surrounding the device according to the invention.

The Fig. 2-4 show the device of the invention Fig. 1 when receiving a bag 1 by the pivoting device 6. This is pivotable about a pivot axis which extends horizontally and tangentially to an imaginary circle about the axis of rotation 10 of the rotary column 9. Two pivot arms are rigidly connected to each other and carry at their ends grippers with which an empty bag 1 can be taken in a horizontal storage position here.

The second holder 13 is located, seen in the direction of rotation of the filling device 2, at this time at the very beginning of the guide 14 and can already be aligned in the radial direction with a filling opening 15. At the time of the pivoting movement of the pivoting device 6, the holders 12, 13 do not necessarily have to be at the beginning of the guide 14. The pivoting device 6 can, in the vertical position of the bag 1 (see Fig. 5-7 ), also wait for the retracting holders 12, 13. Also, an alignment with the filling opening must not be given, this is only after the opening of the bag 1, namely during the attachment of the bag 1, required.

In Fig. 4 the structure of the first holder 12 and second holder 13 can be seen. In order to better recognize the details of the holders 12, 13, only part of the carrier 16 is shown to the left of the rotary column. The first holder 12 has two pairs of pivot arms 17, between which a means for suction, here a suction nozzle 19, is held. The pivot arms 17 are articulated on one side to the suction nozzle 19, on the other side to a rotatable arm 26 (see Fig. 24, 25 ), which is rotatably mounted on the rotary column 9. Thus, the first holder 12 moves in space along a circular arc. By the pivot arms 17, which is designed as a parallelogram, the suction nozzle 19 can be raised or lowered parallel to the axis of rotation 10. The suction nozzle 19 is additionally mounted radially displaceable relative to the pivot arms 17 here by means of a piston 18. The second holder 13 also has two pairs of pivot arms 17, between which a means for sucking, here a suction nozzle 19, is held. The pivot arms 17 are articulated on one side to the suction nozzle 19, on the other side on a guide member which is displaceable in the guide rail of the guide 14. The pivot arms 17 realize here a parallelogram. The guide rail here has the shape of a circular arc which is concentric with the axis of rotation 10. By the pivot arms 17, the suction nozzle 19 can be raised or lowered parallel to the axis of rotation 10. The suction nozzle 19 is not mounted radially displaceable here.

The holders 12, 13 and their suction nozzles 19 are located in the Fig. 2-4 in the transfer position, where an empty bag 1 can be taken over by the pivoting device 6.

The trajectories of the holders 12, 13 are formed as concentric circular arcs to the axis of rotation 10 and therefore extend parallel to each other. The trajectory of the first holder 12, more precisely the trajectory of the mounting of the pivot arms 17, extends within the filling openings 15, the trajectory of the second holder 13, more precisely the trajectory defined by the guide 14, extends outside the filling apertures 15. The guide 14 of the second holder 13 is arranged radially outside of the carrier 16, the second holder 13 is always partially radially inside and partially radially outside of the carrier 16 and the largest diameter of the filling device. 2

The holders 12, 13 are, as will be described, clocked about the axis of rotation 10 moves, namely always a piece about the rotation axis 10 in one direction and then rotated a piece in the other direction and then a piece in the one direction, and so on, while the filling device 2 rotates continuously at a constant speed about the axis of rotation 10, so neither the direction of rotation nor the rotational speed changes.

The Fig. 5-7 show the device of the invention Fig. 1 after swinging up a bag 1 by the pivoting device 6. The two pivot arms of the pivoting device 6 have the empty bag 1 pivoted from the horizontal storage position into a transfer position perpendicular here. In this case, the pivot arms of the pivoting device 6 protrude radially to the outer end of the filler neck 3 in the filling device 2. The bag 1 is located with its side facing away from the rotary column 9 wall on the suction nozzle 19 of the second holder 13. The piston 18 of the first holder 12, which piston 18 carries the suction nozzle 19, is displaced radially outwards until this suction nozzle 19 rests against the bag 1, on its side facing the rotary column 9 wall. Now the bag 1 can be held by means of the suction nozzles 19 and the grippers of the pivoting device 6 can be released. The pivoting device 6 is pivoted back again and can take the next bag 1 with the grippers.

The Fig. 8-10 show the device of the invention Fig. 1 when attaching the bag 1 to the filling opening of the filler neck 3. For this purpose, the bag 1 must first be opened by the holders 12, 13. This happens here in that the piston 18 of the first holder 12 is again moved radially inward and the sucked, the rotary column 9 facing wall of the bag 1 is pulled radially inward. The pivot arms 17 of the holders 12, 13 can then be lifted, so that the bag is pushed onto the outside of the filler neck 3. Then the bag 1 is pressed by a pair of clamps, which acts only centrally on the filler neck 3, against the filler neck 3 and thus taken over by the holders 12, 13. After the pivot arms 17 have been lowered, the clamps 11 are applied to the filler neck 3, so that it is completely enclosed by the brackets 11, and thereby the bag 1 attached to filler neck 3.

During these operations - opening and attaching the bag 1 - moves the second holder 13 along the guide 14 in synchronism with the filling device 2, so has the same angular velocity with respect to the axis of rotation 10 of the rotary column 9 as the filling device 2. Also the first holder 12 is moved synchronously with the filling device 2, ie has the same angular velocity with respect to the axis of rotation 10 of the rotary column 9. Instead of the rotatable about the axis of rotation 10 arm 26 (see FIGS. 24 and 25 ) of the first holder 12, such as by means of a mounted on the rotary column 9 gear, could also be a rail or link fixed to the filling device 2, for example on the carrier 16 may be provided. The first holder 12 could then be fixed when opening and attaching the bag 1 relative to the filling device and only then back process against the direction of rotation along, for example, the rail or gate back to record the next bag 1.

The first holder 12 is after attaching the bag 1 through the brackets 1 on the filler neck 3 again by a rotational movement of the arm 26 in the transfer position according to the Fig. 2-7 moved back. The second holder 13 is after securing the bag 1 through the brackets 1 on the filler neck 3 again along the guide 14 in the transfer position according to the Fig. 2-7 moved back.

The Fig. 11-13 show the device of the invention Fig. 1 when filling a bag 1. The flap 24 is already here in the folded up state. The inclination of the vibrating plate 8 with respect to the rotary column 9 or its axis of rotation 10 is about 15 ° and is not adjustable here. The holders 12, 13 have been omitted in these illustrations. It recognizes the brackets 11 better, which fix the bag 1 at the filler neck 3. Bulk material is now, in particular in a by measurement, such as weighing, predetermined amount, filled in the hopper 4 and passes through the filler neck 3 in the bag 1. The bag 1 is now on the inclined vibrating plate 8, whereby the bulk material is compacted in the bag 1. The flap 24 at the lower end of the vibrating plate 8 supports the filled bag 1 in the bottom area.

If instead of the flap 24 a linearly displaceable plate is provided, which encloses a fixed angle, for example 90 °, with the vibrating plate 8, this plate would then be in Fig. 13 exactly in the same position as the drawn flap 24. Between the plate and the vibrating plate 8 would then be no distance.

The flap 24 could be out of the second position as shown in FIG Fig. 13 is shown, removed again and direction first position, as in Fig. 1 is shown, moved, and be transferred again to the second position. The flap 24 would exert a shock on the bottom of the filling or the already filled bag 1. Also, several such shocks to the bottom of the filling and / or the already filled bag 1 are conceivable. Even with a linearly displaceable plate such shocks could be performed.

The Fig. 14-16 show the device of the invention Fig. 1 when retracting the bag removal device 7 in the direction of the filling device 2. As soon as the bags 1 are completely filled and the bulk material is compacted, the bag 1 can be removed from the filling device 2. For this purpose, the corresponding gripping means 23 of the bag removal device 7 should also move with the filling device 2. For this purpose, a space-fixed guide 20 is provided, which in this embodiment is circular arc-shaped and concentric with the axis of rotation 10, so that the gripping means 23 can be carried along a circular arc with the filling device 2. In order to remove the filled bag downwards and outwards from the filler neck 3, the gripping means 23 are mounted on two pairs - relative to the guide 20 and the gripping means 23 - pivotable arms 21, 22 to realize a parallelogram. The flap 24 is located in the Fig. 14-16 still in the second, so the folded position. If instead of the flap 24 a linearly displaceable plate is provided, which encloses a fixed angle, for example 90 °, with the vibrating plate 8, this plate would then be in Fig. 14 exactly in the same position as the drawn flap 24th

In the Fig. 14-16 are the gripping means 23 - seen in the direction of rotation of the filling device 2 - at the beginning of the arc 20 defined by the guide. The gripping means 23 are now inwards and upwards in the Filling device 2 pivoted so that the gripping means 23 can grip the bag 1. The gripping means 23 are thereby moved along the guide 20 at the same speed with the filling device 2.

The Fig. 17-19 show the device of the invention Fig. 1 before removing the filled bag 1 from the filling device 2 by the bag removal device 7. The flap 24 is here already folded down to the first position. If instead of the flap 24, a linearly displaceable plate would be provided which includes a fixed angle, for example 90 °, with the vibrating plate 8, this plate would then in the Fig. 17 and 19 moved away from the vibrating plate 8 down as below Fig. 1 described. Until the gripping means 23 have reached the end of the guide 20, the gripping means 23 have seized the bag 1. After the gripping means 23 have grasped the bag, the clamps 11 open and the bag 1 is set down. Already at the same time or only then swing the arms 21, 22 outwards and downwards.

The Fig. 20-22 show the device of the invention Fig. 1 after the back pivoting of the bag removal device 7 away from the filling device 2. The bag 1 is still held by the gripping means 23 and can be parked, for example, on a arranged below the bag removal device 7 conveyor belt by loosening the gripping means 23 and transported away. Before and while the bag 1 is turned off, it is spread in the head space of the bag 1 for a proper transfer by means of the gripping means 23.

Fig. 23 shows an example of how the space-fixed guide 14 of the second holder 13 may be performed. The longitudinal ends of the guide rail of the guide 14 are mounted on fixed spacers 25. These pillars 25 need not be specially provided for the guide 14, it can be used existing stand 25, which are about part of a housing that surrounds the device according to the invention.
