1 shows a side view of a first embodiment of a packaging device according to the invention 10 for press packing of trees 9 with a base frame 1 and a pressing device 21 for horizontal pressing and compressing the trees 9 , The basic frame 1 is an L-shaped welded construction, consisting of molding tubes ( 2 ), which are arranged parallel to each other. The L-shape is supported by a support surface 11 and one perpendicular to the support surface 11 standing front wall 8th of the basic frame 1 educated. By this configuration of the base frame 1 is a pressing volume 20 for the trees 9 given, whereby the pressing volume 20 a larger volume than the finished pressed bale 15 having. The length of the base frame 1 depends on the desired bale size and the desired density, but is advantageously designed so that the bearing surface 11 twice the width of a finished bale 15 having.

The basic frame 1 can be supplemented with plates to a closed bearing surface 11 or a closed end wall 8th to build. Loose materials such as brushwood or loose shrubbery can be compressed without losing part of the pressed material.

The pressing device 21 serves to reduce the pressing volume 20 and in the embodiment comprises the 1 a partially unfolded, the bearing surface 11 arranged opposite and the pressing volume 20 final lid 2 , The lid 2 has one of the front wall 8th opposite and to the support surface 11 Outstanding Verschubstück 6 on.

The lid 2 is like the basic frame 1 made of molded tubes and at the top of the front wall 8th about a joint 13 with the base frame 1 connected. The joint 13 is in this embodiment, a hinge joint and allows lifting or tilting of the lid 2 to the base frame 1 around the joint 13 , This is a simpler loading and unloading of the base frame 1 possible. The lid 2 It can be optionally opened via a rope and / or chain construction, hydraulic or pneumatic cylinders or manually upwards.

The lid 2 is designed as a two-part construction, wherein the main part is constructed of hollow profiles, which over the joint 13 on the front wall 8th are hung up. The second part consists of smaller hollow profiles which are introduced with one end in the larger mold tubes of the main part and can be moved axially in this.

At the other end of the smaller hollow sections is the Verschubstück 6 appropriate. The Verschubstück 6 also consists of molded tubes, is rake-shaped and has several vertically from the lid 2 down in the direction of the support surface 11 extending extensions 12 on. The extensions 12 act like fingers and reach into the spaces between the mold tubes of the support surface 11 one. The Verschubstück 6 can by the telescopic design of the molding tubes of the lid 2 in the direction of the joint 13 , with the lid closed 2 parallel to the support surface 11 in the direction of the front wall 8th to be moved ( 6 ). The smaller diameter forming tubes slide axially in the larger diameter forming tubes of the lid 2 and the Verschubstück 6 is moved telescopically. The Verschub process can be performed hydraulically, pneumatically or via cables and / or chain hoists.

At the opposite of the front wall 8th lying side of the base frame 1 is at the contact surface 11 one the loading space or the pressing volume 20 limiting back wall 3 appropriate. The back wall 3 exists like the support surface 11 and the front wall 8th also from parallel forming tubes and extends at right angles from the shelf 11 upwards and is at the connection between the back wall 3 and the shelf 11 tiltable or removable. For example, after the compression process, the back wall 3 be folded down, thereby unloading the base frame 1 is relieved.

The basic frame 1 is on a three-point hitch 4 , at the back of the front wall 8th suspended. The three-point hitch 4 serves for the suspension of the packing device 10 , as in 1 shown on an agricultural implement, such as a tractor or similar towing vehicles 14 , The three-point hitch 4 serves to transport the packing device 10 It can be the base frame 1 Alternatively, it can be attached directly to a trailer hitch or the like and have wheels, so that the packing device 10 as a trailer of a towing vehicle 14 can be transported.

The packing device 10 includes a guide device 23 for fasteners 24 for fixing and packaging the pressed bales 15 , The fasteners 24 can vary depending on the type of trees to be packed 9 or the plant material, for example, cords, ribbons, ropes, straps or chains. For easier handling and easier positioning of the fasteners 24 These are through the guide device 23 already at least partially around the bale 15 guided.

For this purpose, the guiding device comprises 23 each along the forming tubes of the support surface 11 and the front wall 8th of the basic frame 1 arranged guide rails 16 (please refer 2 and 9 ). Here is the fastener 24 each along each guide rail 16 led or inserted into this. The guide rails 16 are along the support surface 11 and the front wall 8th arranged so that the guide rails 16 until behind or over the pressed bale 15 rich, so the bale 15 partly from the fastener 24 is enclosed. The guide rails 16 advantageously prevent slippage of previously inserted z. As cords or bands during the pressing process. For example, after pressing, the ends of the cords or bands may be the guide rails 16 taken to the rest of the bale 15 and then knotted, thereby saving labor and speeding up the processing.

With the tied bales 15 act on the fasteners 24 in the horizontal direction stronger extension forces ( 10 ), as in the vertical direction, because the compaction of the trees 9 done horizontally. Due to this asymmetric load on the fasteners 24 , or the cords, creates an approximately rectangular bale shape, whereby the finished pressed and tied bales 15 are simply stackable. By the lacing of the bales 15 Moreover, in comparison to the press pack using pallets, there are no side parts or spars for packing the pressed trees 9 necessary.

To handle the finished bales in large companies or international transport 15 but it is still possible to accelerate the bales 15 to stack on Euro pallets. So, for example, two bales each 15 stacked side by side and / or one above the other on a Euro pallet without the entire package reaching a high level. This preserves the stability and the bales 15 can be inexpensively loaded and transported.

In 2 is a view of the device 10 from below in the direction of the support surface 11 shown. The bearing surface 11 of the basic frame 1 consists of rectangular shaped tubes on which on the side of the free ends of the forming tubes of the rear wall 3 are attached. A three-point hitch 4 comprising a linkage of three rods, as for example in each tractor for Hitching or lifting equipment is available on the bulkhead 8th appropriate. At the packing device 10 In this case, for example, holders for bolts or balls for attachment to the tractor are arranged.

At the shelf 11 are also sidewalls 5 mounted on molding tubes and serve the lateral boundary of the loader space or the pressing volume 20 , The side walls can be unloaded 5 removed, folded down or along the shelf 11 attached molding tubes, which serve as adjusting means, pushed apart and fixed. This allows the shelf surface 11 on tree lengths of the trees to be packed 9 from 180 to 240 cm, for example. The side walls 5 consist of molding tubes and the pressing volume 20 is through the sidewalls 5 and the back wall 3 limited. By the thus predetermined shape of the pressing volume 20 is it possible the trees 9 easy to stack in the device 10 and prepare for the pressing or packing process.

In 2 It can be seen that along each mold tube of the support surface 11 and thereafter along each mold tube of the end wall 8th a guide rail 16 extends, in each case a fastening means 24 at least partially around a pressed bale 15 is guided. Thus, the pressed bale 15 be fixed in several places along its longitudinal extent. This allows a particularly good pack and durability of the bale 15 so that it does not cause an undesired falling apart of the bale 15 comes in the event that one of the fasteners 24 tears or gets damaged. In this case, the bale is 15 still fixed in sufficient many other places, so that the durability of the packed bale 15 is guaranteed.

The guide rails 16 are each along the forming tubes of the shelf 11 so far towards the back wall 3 arranged running, so that in each case inserted fastener 24 in the pressed state of the bale 15 until behind the bale 15 is guided. At the form pipes of the front wall 8th are the guide rails 16 arranged so that the fastener inserted therein 24 each side of the pressed bale 15 is led upwards. This arrangement of the guide rails 16 ensures that the ends of the fastener 24 simply from the guide rails 16 taken to the not yet enclosed part of the bale 15 guided and easily connected or linked.

6 shows then the result of the compression process with the above-described first embodiment of the invention with fully retracted Verschubstück 6 , The profile tubes of the lid 2 with smaller diameter are completely sunk in the profile tubes with a larger diameter. Behind the Verschubstück 6 , that is between the Verschubstück 6 and the back wall 3 is the released area, which also represents the reduced volume recognizable. Through the course of the guide rail 16 the guide device 23 along the base frame 1 , the lid 2 and the Verschubstücks 6 is the fastener 24 in the pressed state of the bale 15 completely around the bale 15 guided. For particularly easy fixation of the pressed bales 15 can be an automatic knotting device on the packing device 10 be arranged so that no additional manual operation for linking the fasteners 24 is required. In 6 are the trees 9 in compressed and cuboid bales 15 shown tied state.

All embodiments of the invention with horizontal packing direction can advantageously also have a lifting system, which on the base frame 1 is attached. The lifting system allows the lid 2 vertically along the back wall 8th to adjust so that the height of the predetermined pressing volume 20 can be varied, thereby also the height of the finished bales 15 is flexibly adjustable.
