Description

DK 180312 B1 1

The invention relates to a packaging device for pre-packing trees according to the preamble of claim 1.

Various methods for pressing and packing Christmas trees, decorative greenery and similar plant materials are known, for example, from the international patent application WO9742085 A1 or DK 171396 B1.

In the known methods the trees are pressed and by means of a frame, mostly a wooden frame, kept in shape and fastened to pallets.

However, this method, especially for the retail sale of the trees, entails some disadvantages. The non-standardized form of the pallets used, which for the most part does not comply with the EU pallet target, proves to be problematic. Furthermore, the height of the stacked trees most often exceeds a height of 2.4 m, resulting in a very high weight of a pressed wooden bale of partially over 1500 kg. For erection, the pallets used require a flat surface and tend to tip over when working in the field, which entails an extreme safety risk. Furthermore, the usual filigree construction of the wooden frames causes them to break easily when working in the field. Likewise, in the case of the known systems, the ordinary, large working height during filling of the packing device with trees entails a high safety risk in practice.

The object of the invention is thus to provide a packing device for press-packing wood, which allows a simple and safe handling, which is used independently of pallets and wooden frames, and does not require large working heights or filling flat.

The invention solves this object with a packaging device of the above-mentioned type with the features stated in the characterizing part of claim 1. According to the invention, the packing device comprises a guide device for fastening means for fixing the pressed bales, the guide device comprising at least one guide rail arranged along the bearing surface and end wall of the base frame, and wherein the fastening means is guided along the guide rail so that the bales at least partially of the fastener.

DK 180312 B1 2 In order for the fastening means to be moved effortlessly at least partially around a pressed bale, at least one holding means, in particular movable along the guide rail, can be provided on the guide rail for reversible fastening of the fastening means.

By virtue of the direction of the pressing process in relation to the end wall, it is possible to fill the packaging device flat or from the side, and after the pressing process, for example, to lace the pressing material into bales by means of the fastening means. These bales can then be handled independently of pallets and heavy frame constructions, are smaller and lighter than pallet-borne bales and enable simple storage even in the retail trade.

Thus packed bales can also be rolled directly in the field or, for example, on sales stands, to a designated storage space, without using additional equipment or stackers, which is an advantage in particularly narrow work areas, such as Christmas markets or in dense forests.

Further advantageous embodiments of the device are described in the features of the dependent claims.

To enable a particularly simple fixation of a pressed bale, the guide rail can be arranged extending along the cover and displacement piece of the pressing device, so that in the pressed state the fastening means is guided completely around the bale.

To provide a packing device for securely packing different types of plant materials to be packed, the holding means may be provided in the form of a hook and / or a clamping device for reversibly fastening one end of the fastening means, and the fastening means are cords, ribbons , ropes, straps or chains.

In an embodiment of the invention which is particularly simple in construction, several openings can be arranged continuously along the guide rail in the guide rail, where guide elements are arranged in the openings for guiding the fastening means, which elements can be inserted reversibly.

A particularly effective compaction of plant material to be pressed can be achieved in that the displacing piece of the pressing device for reducing the pressing volume and for pressing and compressing the trees is telescopically displaceable substantially parallel to the laying surface in the direction of the end wall.

DK 180312 B1 3 A structurally particularly simple embodiment of the invention can be provided, where the displacement piece can be designed as a closed plate projecting at right angles to the cover in the direction of the laying surface.

Loose plant material and thinner trees can, without slipping off the displacement piece, be compressed, the displacement piece having a number of parallel, in particular right angles from the cover projecting projections.

The displacement piece thus acts as a rake and further enables, by virtue of the increased number of contact points on the trees, a gentle pressing of the trees.

In order that the packaging device can also be filled from above and not only from the side, it is provided that the cover is attached to the end wall and can be folded up via a hinge, preferably a hinge joint, in particular folded away from the laying surface.

Also for removing the pressed bales, the folding cover allows a simpler handling of the bales.

In order to be able to make the pressing volume larger or smaller, the pressing device can advantageously have a lifting system, where the lifting system is attached to the base frame, and where the cover can be displaced vertically along the rear wall.

In order to work efficiently and faster, it is advantageous to have a machine support.

Therefore, the cover and / or the displacement piece can be provided movably hydraulically and / or via rope or chain drive and / or can be tilted.

This saves workers power and time, and increases the productivity of loading and unloading the packaging device.

The cover and the displacement piece can be made compact, the cover consisting of two sets of profile pipes, each with its own diameter, where one set of profile pipes can be stored and displaced axially into the other special profile pipe. | by virtue of this telescopic

building it is possible to compact the trees very tightly and to obtain extremely small and tightly packed bales.

An efficient and time-saving unloading of the pre-pressed bales from the packing device can be obtained when a loading device is provided, which loading device can be moved starting from the end wall in the direction of the opposite end device.

DK 180312 B1 4 the wall lying side of the deposit surface for laying the bales from the deposit surface.

The packing device can be loaded faster when the bearing surface of the base frame is delimited on both sides. In addition, on the side of the laying surface opposite the end wall, a rear wall, which is perpendicularly projecting from the laying surface and protruding in the direction of the cover, can be provided, where the rear wall can in particular be folded inwards or removed.

In order to be able to place the trees even more accurately in the pressing volume of the packing device and thereby load them more efficiently, on the at least one of the sides of the laying surface one can be provided from the laying surface perpendicular to the direction of the cover, the pressing volume from the side limiting side wall. For loading the packing device with trees of different lengths, it can be advantageous that the side wall can be displaced by means of displacing means, so that the width of the press volume can be made larger.

When emptying the device, it is advantageous when the rear wall and / or the side walls are placed hinged on the laying surface.

The weight of a packing device according to the invention can be reduced if the depositing surface and / or the end wall and / or the side wall and / or the rear wall consist of profile pipes arranged in parallel parallel to each other.

In order also to be able to compress loose plant material, for example, without residues thereof being left uncompressed on the laying surface, the laying surface and / or the back wall and / or the side wall may have slits, whereby the projections engage in the slots in the laying surface and / or in the slits. in the back wall. The manufacture of the packing device can be simplified in that the depositing surface and / or the rear wall and / or the side wall consist of profile tubes arranged parallel to each other, projecting at right angles from the depositing surface, whereby the projections on the displacement piece project into and / or engage in the spaces between the profile tubes. of the laying surface and / or the back wall. In such a design of the packing device, only profile pipes must be welded together, and also

DK 180312 B1 repairs, especially on the base frame, can be easily carried out by means of the weldable profile pipes.

In order to be able to transport the packing device quickly to a field - and also to transport it away again - the packing device can preferably be hooked onto a towing vehicle, in particular a tractor, and the packing device can in particular have wheels and be transported with a towing vehicle, preferably as a trailer.

Thus, it is also not necessary to set aside the packaging device to carry out the press packing.

Thereby this can be carried in a simple manner to the storage place for the trees to be packed, whereby the way for the workers to the packing device during loading and emptying of the packing device can be reduced.

The control of the fastening means for the packing of the bales around a pressed bale can be facilitated by the control device having a motor drive driven in particular by the towing vehicle.

In order to provide a packing device which is particularly simple and compact in construction, several reversibly connectable or clampable fixing means can be arranged along the guide rail, where the fastening means inserted in the guide rail is kept fixed in the guide rail by means of the fixing means.

Further advantages and embodiments of the invention appear from the description and the accompanying drawings.

Examples of embodiments of the invention are shown schematically in the drawings and are described, for example, in the following with reference to the drawings.

Schematic is shown: Fig. 1 is a side view of a first embodiment of the packaging device, FIG. Fig. 2 is a bottom view of the depositing surface of the packaging device; Fig. 3 is a plan view of the base frame in the first embodiment of the packaging device; 4, fig. Fig. 5 is a plan view and a side view of the first embodiment of the packing device with loaded trees; 6 is a side view of the first embodiment of the packaging device during the pressing process,

DK 180312 B1 6 Fig. Fig. 7 is a side view of another embodiment of the packaging device; Fig. 8 is a side view of the second embodiment of the packaging device during the pressing process; Fig. 9 is a cross-sectional view laid through the laying surface with trees placed thereon; 10 is a schematic view of the tensioning forces acting in a constricted bale.

FIG. 1 shows a side view of a first embodiment of a packing device 10 according to the invention for pressing packing of trees 9 and with a base frame 1 and a pressing device 21 for horizontal pressing and compaction of the trees 9. The base frame 1 is an L- shaped welding structure consisting of profile pipes (Fig. 2), which are arranged parallel to each other.

The L-shape is formed by a laying surface 11 and an end wall 8 of the base frame 1 perpendicular to the laying surface 11. By virtue of this design of the base frame 1, a press volume 20 is defined for the trees 9, which press volume 20 has a larger volume than the pre-pressed bale 15. The length of the base frame 1 adjusts to the desired bale size and the desired compression density, but is preferably designed so that the laying surface 11 has twice the width of a finished bale 15. The base frame 1 can be supplemented with plates to form a closed depositing surface 11 or a closed end wall 8. Thus, loose materials such as branches or loose shrubs can also be compressed without a part of the pressed material being lost.

The pressing device 21 serves to reduce the pressing volume 20 and comprises in the embodiment in fig. 1 shows a partially opened, opposite the laying surface 11 and the closing volume 20 terminating the cover 2. The cover 2 has a displacement piece 6 opposite the end wall 8 and projecting towards the laying surface 11, the cover 2 is made up of profile pipes like the base frame 1 and is at the upper end of the end wall 8 connected to the base frame 1 via a joint 13. The joint 13 is in this embodiment a hinge joint and enables a raising or tilting of the cover 2 relative to the base frame 1 around the joint 13. Thus a simple loading and unloading of basic frame 1 possible.

The cover 2 can thus optionally be folded upwards

DK 180312 B1 7 via a rope and / or chain construction, via hydraulic or pneumatic cylinders or manually. The cover 2 is designed as a two-part construction, where the main part is built up of hollow profiles which are suspended via the joint 13 on the end wall 8. The second part consists of smaller hollow profiles which are inserted with one end into the larger profile pipe of the main part and can be displaced axially therein. At the other end of the smaller hollow profiles, the displacement piece 6 is arranged. The displacement piece 6 also consists of profile pipes, is shaped like a rake and has projections 12 projecting perpendicularly from the cover 2 downwards towards the laying surface 11. The projections 12 thereby act as fingers and engage in the laying surface 11 through the spaces of the profile pipes. Due to the telescopic design of the profile tube of the cover 2, the displacement piece 6, when the cover 2 is closed and in the direction of the joint 13, can be pushed parallel to the depositing surface 11 in the direction of the end wall 8 (Fig. 6). Thereby, the profile tubes of smaller diameter slide axially into the profile tubes of the larger diameter of the cover 2, and the displacement piece 6 is moved telescopically. The displacement process can be performed hydraulically, pneumatically or via rope pulls and / or chain pulls. On the side of the base frame 1 lying opposite the end wall 8, a rear wall 3 limiting the load space 11 or the pressure volume 20 is arranged at the laying surface 11, the rear wall 3 consists, like the laying surface 11 and the end wall 8, of parallel profile pipes and extending upwards at a right angle from the deposition surface 11 and can be tilted or removed at the connection between the rear wall 3 and the deposition surface 11. Thus, for example, the rear wall 3 can be folded down after the compaction process, whereby emptying of the base frame 1 is facilitated.

The base frame 1 is suspended by a three-point suspension 4 on the back of the end wall 8. The three-point suspension 4 serves for suspending the packing device 10, as shown in fig. 1, on an agricultural equipment, such as a tractor or a similar towing vehicle 14. The three-point hitch 4 serves to transport the packing device 10, and it may be mounted on the base frame 1 or alternatively directly on a trailer coupling or the like and have wheels, thus that the packing device 10 can be transported as a trailer on a towing vehicle 14.

The packing device 10 comprises a guide device 23 for fastening means 24 for fixing and packing pressed bales 15. The fastening means 24 may, depending on the nature of the trees 9 or the plant material to be packed, be, for example, strings, ribbons, twine ve, straps or chains. For simpler handling and easier positioning of the fastening means 24, these are by means of the guide device 23 already at least partially guided around the bale 15. For this purpose the guide device 23 each comprises guide rails arranged along the profile tube 11 and the end frame 8 of the base frame 1. 16 (see Fig. 2 and Fig. 9). Thereby, the fastening means 24 is always guided along each guide rail 16 or inserted therein. The guide rails 16 are arranged along the laying surface 11 and the end wall 8 so that the guide rails 16 extend to behind or over the pressed bale 15, so that the bale 15 is partially enclosed by the fastening means 24. The guide rails 16 advantageously prevent a displacement of the pre-inserted eg strings or ribbons during the press process. Thus, after pressing, for example, the ends of the cords or straps can be picked up by the guide rails 16, passed around the rest of the bale 15 and then tied in a knot, whereby working time can be saved and faster working progress is achieved.

On the constricted bale 15, stronger pulling forces (Fig. 10) act on the fastening means 24 in the horizontal direction than in the vertical direction, the compaction of the trees 9 taking place horizontally. | by virtue of this asymmetrical load of the fastening means 24 or the strings, an almost rectangular bale shape is formed, whereby the pre-pressed and laced bales 15 can be easily stacked. | Furthermore, by virtue of the constriction of the bale 15, in comparison with press packing using pallets, side parts or beams for packing the pressed trees 9 are not necessary.

In order to increase the pace of handling the finished bales 15 in large companies or international transport, it is still possible to stack the bales 15 on EU pallets. Thus, for example, one can stack two bales 15 next to each other and / or on top of each other on an EU pallet, without the whole package having a great height. Thus, the stability is maintained and the bales 15 can be loaded and transported in an economical manner.

DK 180312 B1 9 In fig. 2 shows a picture of the device 10 seen from below in the direction of the laying surface 11. The laying surface 11 of the base frame 1 consists of box-shaped profile pipes, the rear wall 3 being arranged on these on the side with the free ends of the profile pipes.

Arranged on the end wall 8 is a three-point suspension 4 comprising a rod system with three rods, as is the case, for example, with any tractor for coupling or raising work equipment.

In this case, for example, holders for bolts or balls for mounting on the tractor are arranged on the packing device 10.

On the depositing surface 11, side walls 5 are also arranged over profile pipes and serve for lateral delimitation of the cargo space or the press volume 20. When emptying, the side walls 5 can be removed, folded down or slid apart along the profile pipes arranged on the depositing surface 11, which serve as adjustment means. clay, and gets fixed.

Thereby, the laying surface 11 can be set to tree lengths of the trees 9 to be packed, of eg 180 to 240 cm.

The side walls 5 consist of profile tubes, and the pressing volume 20 is limited by the side walls 5 and the rear wall 3. Through the shape of the pressing volume 20 thus assumed, it is possible to stack the trees 9 in a simple manner, to place them in the device 10 and to - prepare the press or package process.

In fig. 2 it is seen that a guide rail 16 extends along each profile tube in the laying surface 11 and coupled thereto along each profile tube in the end wall 8, in each of them a fastening means 24 is passed at least partially around a pressed bale 15. Thus, the pressed bale 15 can be fixed in its longitudinal direction in several places.

Thereby a particularly good packing and durability of the bale 15 is obtained, so that it does not end with an undesired splitting of the bale 15 if one of the fastening means 24 is torn over or damaged. | in this case, the bale 15 is fixed in a sufficient number of additional places, so that the durability of the packed bale 15 is ensured.

The guide rails 16 extend along the profile tube of the laying surface 11 so far in the direction of the rear wall 3 that the fastening means 24 inserted therein in the pressed state of the bale 15 is led to behind the bale 15. The guide rails 16 are arranged on the profile tube 8 of the end wall 8. , that the fastening means 24 inserted therein is guided laterally upwards towards the pressed bale 15. This arrangement of the guide rails 16 ensures that the ends of the fastening means 24 can be removed from the guide means in a simple manner.

DK 180312 B1 10 the rails 16, run around the not yet enclosed part of the bale 15 and are effortlessly connected or connected. FIG. 3 shows a plan view of yet another embodiment of the packing device 10, in which the cover 2, the displacement piece 6 and the front part of the profile pipe of the laying surface are depicted. The displacement piece 6 is attached to the cover 2 by the profile pipes of smaller diameter, which are then partially inserted and arranged in the profile pipes of the larger diameter of the cover 2. The finger-like projections 12 of the displacement piece 6 engage between the profile tubes in the depositing surface 11 and the rear wall 3, so that also short plant material or trees 9 with thin trunks can be compressed without releasing the displacement piece 6 during the pressing process.

FIG. 4 is a schematic view of the placement of the trees 9 before they are compacted.

The trees 9 are stacked next to each other or on top of each other up to the upper edge of the end wall 8 or the back wall 3. | fig. 4 further shows how the trees 9 can be placed space-saving alternately with the tip of a tree 9 next to the foot of a further tree 9.

FIG. 5 shows an embodiment of the invention, in which the guide rails 16 of the guide device 23 extend not only along the base frame 1, but also along the cover 2 and the displacement piece 6 in the pressing device 21, so that the fastening means 24 inserted therein completely encloses a pressed bale 15.

FIG. 6 then shows the result of the compression process with the above-described first embodiment of the invention with fully inserted displacement piece 6. The smaller diameter profile tubes of the cover 2 are completely recessed in the larger diameter profile tubes. Behind the displacement piece 6, and thus between the displacement piece 6 and the rear wall 3, the exposed area is seen, which also shows the reduced volume. Through the course of the guide rails 16 of the guide device 23 along the base frame 1, the cover 2 and the displacement piece 6, the fastening means 24 is guided in the pressed state by the bale 15 all the way around the bale 15. For particularly simple fixing of the pressed bale 15, an automatic binding direction of the packing device 10 so that no further manual work steps are required to bind the fastener 24. | fig. 6, the trees 9 are shown in the compressed and to a rectangular shape constricted bale 15.

All embodiments of the invention with horizontal packing direction can advantageously also have a raising system which is attached to the base frame 1. The raising system makes it possible to adjust the cover 2 vertically along the rear wall 8, so that the height of the predetermined press volume 20 can is varied, whereby also the height of the pre-pressed bale 15 can be adjusted flexibly. FIG. 7 is a side view of another embodiment of the vertical compression direction packing device. The vertical embodiment of the invention comprises a base frame 1 with a depositing surface 11 and an end wall 8 arranged approximately perpendicularly to the depositing surface 11, whereby a pressing volume 20 is delimited to trees 9. On the side of the depositing surface 11 lying on the opposite end wall 8 a rear wall 3 is arranged, which extends at right angles up from the depositing surface 11 and at the coupling between the rear wall 3 and the depositing surface 11 can in particular be tilted or removed outwards. Side walls 5 can also be arranged on the laying surface 11, which can be reversibly displaced and removed over profile pipes.

The packing device 10 further comprises a pressing device 21 with a cover 2, the cover 2 being arranged opposite the depositing surface 11 on the end wall 8. The cover 2 is in fig. 7 shown with an opposite tear-off surface 11 and projecting from the end wall 8, tear-shaped displacement piece 6 or consists thereof. During the pressing process, the displacement piece 6 is moved hydraulically, pneumatically or via rope or chain pull vertically along the end wall 8 in the direction of the depositing surface 11, whereby the displacement piece 6 engages between the profile pipes in the rear wall 3.

In the case of a packing device 10 with a vertical compression direction, the cover 2 or the tear-shaped displacement piece 6 can alternatively be arranged opposite the depositing surface 11 on the rear wall 3. In this case the displacement piece 6 engages between the profile pipe of the end wall 8 and moves along the rear wall 3 towards the deposition surface 11 A vertical compression direction packing device 10 includes a fastener guide device 23 for simple fixation and packing of pressed bales 15. The guide device 23 thereby has guide rails 16 through which the fasteners 24 are passed at least partially around the pressed bale 15. .

DK 180312 B1 12 In fig. 7, the packing device 10 is suspended on a three-point suspension 4 arranged on the rear side of the end wall 8, but it may alternatively also comprise wheels and may on the rear side of the end wall 8 be arranged directly on the trailer coupling of a towing vehicle 14.

FIG. 8 is a side view of the device shown in FIG. 7 with vertical compression direction, where the trees 9 have already been compressed by the displacement piece into a bale 15.

All embodiments of the invention can be arranged such that the guide rail 16 is for instance manufactured as a plastic and / or metal rail, along which several openings are provided in the guide rail 16. | each opening may be provided with a reversible plug-in guide element such as a locking pin or split for guiding the fastening means 24. This simple embodiment of the invention makes it possible, before the packing device 10 is loaded with trees 9, that the fastening means 24, e.g. a cord or strap, is held in place along the guide rail 16 with the guide elements. Then the packing device 10 is loaded with trees 9, and the pressing process from trees 9 to a bale 15 is carried out. For fixing or constriction of the bale 15, only the ends of the fastening means 24 now have to be tied together, whereby the guide elements advantageously open and the fastening means 24 are released. The pre-pressed and constricted bale 15 can then be removed.

Alternatively, all embodiments of the invention may be designed so that several reversibly connectable or clampable fixing means are arranged along each guide rail 16, which serve for fixing the fastening means 24. The fixing means may, for example, be clamps. In this particularly simple embodiment, the fastening means 24, for example a string or a band, is fastened in several places along the guide rail 16 with fixing means before loading the packing device 10, the fixing means being coupled or clamped on the guide rail 16. When fixing or tightening the pressed bale 15 advantageously detaches the fixing means from the guide rail 16 and releases the fastening means 24.

As further alternatives to the above-described embodiments of the guide device 23, at least one holding means, in particular movable along the guide rail 16, can be arranged on the guide rail 16 for reversibly fastening the fastening means.

DK 180312 B1 13

24. These may, for example, be several holding means stationary along the guide rail 16, such as clamping devices, in which the fastening means 24 can be reversibly clamped. In this case, the holding means can be, for example, screwed or welded clamps on the guide rail 16.

Alternatively, the holding means may also be a hook movable along the guide rail 16 and / or a movable clamping device for reversibly fastening one end of the fastening means 24. To this hook a first end of the fastening means 24 can be fastened and at least partially guided around the pressed bale 15 , the hook being moved along the guide rail 16.

The other end of the fastener 24 is optionally located, as seen in FIG. 6, in a storage unit 17 arranged on the base frame 1, from which the fastening means 24, for example a wire or a string, are wound. Thereby, the fastening means 24 can either be prepared in predefined lengths, so that for fixing the pressed bale 15 only the two ends of the fastening means 24 have to be connected. However, it can advantageously also be provided that the fastening means 24 is unrolled from a in the storage unit 17 being a roller, so that a piece of the fastening means 24 can be flexibly cut off depending on the size of the pressed bale 15 and the pressed bale 15 fixed. All embodiments of the invention can optionally be designed so that the control device 23 prevails over a motor drive driven in particular by the towing vehicle 14. The guide rails 16 in this case are designed as guide profiles for chains or ropes, the chains pulling the fastening means 24 around a pressed bale 15. For example, a hydraulic motor in this case pulls gears which engage the chains and move them along the guide rail 16. An end of the fastening means 24, for example a string, is attached to the holding means, for example a hook, which is arranged movably next to the guide rail 16. At the end of a guide rail 16, a chain catcher is arranged, which prevents the retracted chain from performing a pendulum movement. In all embodiments it is also possible for the depositing surface 11 and / or the rear wall 3 and / or the side wall 5 to have slots, the projections 12 on the tear-like displaced piece 6 engaging in the slots in the depositing surface 11 and / or projecting and / or engages in the slots in the rear wall 3.

Alternatively, in all embodiments of the invention, it may also be planned that the displacement piece 6 is designed as a closed plate which is at right angles to the cover 2 in the direction of the deposition surface 11. In the following, the winding of the compression process is briefly described in connection sharing with a package device 10 with horizontal compression direction:

To begin with, the device 10 is brought to and set up at the place where the trees 9 are harvested, by means of a towing vehicle, eg a tractor.

The cover 2 is opened and folded upwards around the joint 13. The displacement piece 6 is, in front or adjacent thereto, fully extended and is located at the end of the cover 2. The rear wall 3 and any side walls 5 are brought into a vertical position and adjusted with the laying surface 11 of the base frame 1 in the desired width (Fig. 1 and Fig. 2). Now the fastening means 24, for example cords, ribbons, chains or ropes, are inserted into the guide rails 16 and fixed there.

Next, the trees 9, branches or loose shrub material are introduced so that the trunks lie across the pressing direction and, if necessary, are bounded by the side walls 5 (Fig. 4). The cover 2 is closed, whereby the displacement piece 6 is pulled out completely and should be located at the rear end of the device 10, so that the luggage is not damaged (Fig. 5). During the pressing process, the displacement piece 6 is now moved in the direction of the end wall 8, approximately parallel to the laying

surface 11 until the desired packing depth is reached (Fig. 6). | force of the side walls 5 prevents the pressed goods from being pushed apart.

Then the strings or bands arranged in advance in the guide rails 16 are tied together and the bale is tightened.

The displacement piece 6 is again pulled out in the end position, the cover 2 is folded up and the rear wall 3 is folded away.

The finished bales 15 can then be taken out of the

Alternatively, the bales 15 with a loading device which, starting from the end wall 8 in the direction of the side opposite the end wall 8, can be moved along the depositing surface 11, can be transported with the depositing surface 11.
