Description

The present invention relates to a press with at least one docking and decoupling collection trolley for pressed material to be pressed, the press having a baling chamber, the collection trolley having a collecting space with a bottom and walls, wherein when coupled to the press collection trolley in this collected pressed material machine can be transferred from the collection truck into the baling chamber, wherein at least the bottom of the collecting truck for its emptying from a lower collection position is movable upwards and backwards, wherein a conveyor is provided, with the at least coupled to the press collection carriage moving at least the bottom above the pressed material located in the collecting space can be conveyed to the pressing space of the press, and wherein in the state decoupled from the press the collecting trolley can be filled at a location remote from the press with pressed material to be pressed.

For example, in large-scale shops, such as hypermarkets or large supermarkets, generally collected in the removal of merchandise from larger transport packaging packaging material is collected as pressed material to be pressed in collecting trolleys in order then to a central press, in particular baler fed. Common collection cars have a base area that corresponds approximately to the base of a Euro pallet. They are equipped with casters and are pushed by the operating staff through the aisles of the sales room. On their sides, the collection cars are usually provided with side walls as a lateral boundary. Since the loading of the collection car generally occurs from the top, the side walls have a height that allows this loading effortlessly. When a collection truck is filled, the operator drives with this to the central press, where the contents of the collection car is unloaded. This unloading of the pressed material collected in the collection truck is carried out either manually or mechanically supported. With manual emptying the pressed material z. B. removed from the operator from the collection car and either in the storage room of a baler, z. B. according to WO 2008/113465 A1 , filled or the pressed material is inserted through the feed opening of a horizontal baler eg in the baling chamber. If this press room is filled so far that no further pressed material fits, then the feed opening is closed and a press plate compacts the pressed material. This procedure is disadvantageously time consuming and tedious.

A relief and time saving provide from the relevant practice known solutions for horizontal balers, in which a collection cart is placed in a lifting and tipping device, which is associated with the press. After locking the collecting truck in the lifting and tipping device of the collection trolley is lifted by the device and tilted about a horizontal axis by about 180 °, whereby the contents of the collecting truck falls into the hopper of the baler or in the filling of a press container. From this storage or filling room, the material to be pressed is then removed by suitable means, e.g. a compressor screw, either in the press container or in the baler promoted. A disadvantage of these solutions is in particular the space required for the lifting and tilting device and for the subsequent collection space. In addition, in high-lying filling openings of presses for lifting and tilting of the collection truck by means of the device, a high space is required, which is often not available, so that such presses with lifting and tipping device can then be placed only in the open area, where they Weather are exposed and what causes longer transport routes in the supply of pressed material to be pressed.

From the document JP 2002-126 897 A is a press of the type mentioned above. With this press, collected in a collecting trolley disposal material is pressed by successively the following steps: the collection trolley with the waste material is taken into a car receiving chamber, a bottom plate of the collecting trolley is lifted by a fork and the disposal material is pressed from the collection trolley in a transport box and pre-pressed. Then, the transport box into which the pre-pressed waste material has been pressed is moved straight sideways over a press chamber of the press while the fork is lowered to a bottom dead center position and the bottom plate to the bottom of the collecting truck is returned. Finally, the pre-pressed waste material from the transport box is pushed into the pressing chamber by a lowering operation of a pressing plate, pressed against the bottom of the pressing chamber and pressed.

In this known press is considered to be disadvantageous that only certain press products are suitable for transport by means of the transport box, which must be open at the top and bottom, namely those that are sufficiently firmly clamped during pre-pressing in the transport box, without thereafter in parts or even completely automatically fall out of the transport box out again. Such a risk exists in particular with flat stratified pressed material, such as paper or cardboard. Thus, the range of use of the press is limited in terms of workable press products.

For the present invention, therefore, the object is to provide a press with at least one on and disconnectable collection car, which avoids the disadvantages mentioned above and in the case of low space requirements, especially in terms of the required height, a technically reliable, simple and easy to use staff contribution is ensured by collected, to be pressed pressed material of various kinds in the press.

The solution of this object is achieved according to the invention with a press of the type mentioned above, which is characterized in that the conveyor as the present in the collection cart to be pressed material in the movement of at least the bottom upwards gradually and continuously from the top of the collection cart decreasing and the press feeding conveyor is executed.

Essential to the invention, the removal of the material to be pressed from the collection trolley takes place gradually from above, for which at the same time at least the bottom of the collecting trolley is steadily raised. The lifting of the soil and the removal of the pressed material to be pressed by the conveyor are matched to match. A particularly high lifting of the collecting and tilting about a horizontal axis or a sideways movable transport box are no longer required in the inventive solution. Thus, the press of the invention can be accommodated easily in rooms with normal ceiling height. The press is assigned at least one collection car; in In practice, however, according to the need for to be disposed of pressed material, the press expediently assigned several collection cars. The collection cars are expedient to each other and can each be spent separately for their emptying to the press and coupled to the press.

A preferred embodiment of the press is characterized in that the conveyor is connected to the press or formed as part of the press. The conveyor is required only once by their assignment to the press per press, which is economically advantageous. Technically, it is alternatively also possible that each collection vehicle is associated with a corresponding conveyor.

The conveyor can be configured technically different. Preferably, the conveyor is designed as a milling cutter with a milling drum or with several parallel, in the same direction rotatably drivable milling drums or occupied with conveyor tines drivable conveyor belt or conveyor chain arrangement or as one or more rotary drivable augers existing screw conveyor.

If the conveyor is designed as a milling cutter with a plurality of parallel, in the same direction rotatably driven milling drums, then it is preferably provided that the milling drums carry tines and that the tines of adjacent milling drums with intersecting radii and seen in Fräswalzenlängsrichtung are offset from each other and interlock. As a result, a uniform and intensive conveying effect is achieved over the area of the collecting trolley bottom.

More preferably, the milling rollers can be driven with rotational speeds that are relatively different from one another, wherein a milling drum closest to the pressing space has the highest rotational speed and a milling roller furthest from the pressing chamber has the smallest rotational speed. This ensures that the material to be pressed, which is supplied to the pressing space, is conveyed in the direction of the pressing space at a faster speed and thus pulled apart. This ensures a safe and fast filling process and prevents overloading or even blocking of the milling rollers, in particular of the milling chamber closest to the pressing space or Milling drums. If a feeding device is provided between the conveying device and the pressing chamber, this too is protected against overloading or even blocking.

In this press, all milling drums can advantageously be driven by a common drive via gear elements that are different in each case relative to the drive. The drive can be coupled with each milling drum via a respective transmission element; alternatively, the drive may be e.g. be coupled with the first or last milling drum and the other milling drums are then coupled in each case gear with the adjacent milling drum. In each case, a single motor, e.g. Electric motor or hydraulic motor, for driving all milling drums, which then rotate during operation with fixed rotational speed ratios. Alternatively, individual drives for the milling drums may be provided, which increases the technical complexity, but allows a simple variation of the rotational speed ratios between the milling drums.

A preferred embodiment proposes that the floor is connected to a coupled with the press from the press rear wall of the collecting trolley to an L-shaped bottom wall element and that the floor-wall element relative to the rest of the collection trolley lift - and lowered. This embodiment has the advantage that the lifting device can be arranged above the space occupied by the collecting trolley coupled to the press, wherein the lifting device can act on the upwardly facing wall for lifting the floor-wall element.

As described above, lifting of at least the bottom of the collecting truck is required for the removal of the pressing material to be pressed from the collecting trolley. To realize this lifting function, a lifting device is preferably provided on the press or on the conveyor, by means of which at least coupled to the press collection tray at least its bottom or its bottom wall element can be raised and lowered.

Suitably, the lifting device is formed by at least one vertical, drivable in two directions, circulating endless traction means on the press or on the conveyor, which directly or indirectly engaged with the lifting and lowering part of the coupling of the collecting truck to the press Collecting cart occurs. The circulating endless traction means is well suited as a lifting device due to its technical simplicity and reliability and space-saving design and therefore can be used with advantage.

One embodiment of this press provides that the traction means is in engagement with a lifting carriage guided vertically displaceably on the press or the conveying device, which engages with the lifting and lowering part of the collecting trolley when the collecting trolley is coupled to the press. The lifting carriage, with a suitable design of its own construction and its guiding means, ensures a safe and stable guidance of the lifting and lowering part of the collecting trolley during the transfer of the pressed material from the collecting trolley into the pressing space of the press.

A related development proposes that the traction means is a roller chain, which is guided over two on the press or the conveyor vertically stacked gears, of which at least one is rotatably drivable. The roller chain combines a high load capacity with good durability and low procurement costs, which contributes to a reliable and economical operation of the press.

So that the lifting device can reliably raise and lower the lifting and lowering part of the collecting trolley and thus the conveyor can reliably grasp the pressed material collected in the collecting trolley and convey it into the pressing space of the press, the collecting trolley must be positioned exactly relative to the press and to the conveying device and lifting device , These are preferably provided as a means for coupling the collecting truck to the press on this or on the conveyor and on the collecting carriage interlocking coupling guides and bars. The coupling guides provide for an exact positioning of collection cars and other press relative to each other. The bars ensure the maintenance of the coupling state and are either manually or remotely adjustable.

A first preferred embodiment of the press in this respect is characterized in that the coupling guides are designed as interlocking pairs of rails at the level of the upper edge of two mutually opposite walls of the collecting carriage. In this embodiment, an operator who has the collecting trolley is coupled to the press, the coupling guides due to their arrangement at the level of the upper edge of the walls of the collecting truck well in view, so that the proper positioning of the coupling guides relative to each other is easily possible.

In this regard, an alternative embodiment of the press suggests that are provided as means for coupling the collecting truck to the press rollers of the collecting carriage leading rails at floor level of the installation space of the press. In this embodiment, the rails are removed from the conveyor and the lifting device, so that they do not affect or hinder the technical design of the conveyor or lifting device. Also in this embodiment, an operator can easily dock the collection trolley by pushing the running on his wheels collection trolley in the rails. To facilitate the insertion of the rollers, the rails can be designed at its inlet region with funnel-shaped inlet slopes. For the Ankoppelposition of the collecting trolley, the rails have expediently at least one stop, against which each of the leading roller starts. In addition, means for fixing the carriage can be provided in its Ankoppelposition here.

So that no residues of the pressed material remain in the collecting trolley when removing the material to be pressed from the collecting trolley by the conveyor, it is preferably provided that the bottom of the collecting trolley is formed on the upper side corresponding to the contour of the conveyor facing the ground. If the conveyor is formed, for example, of a plurality of parallel milling drums, the bottom has on its the conveyor facing top expediently the form of appropriately arranged and extending arc sections.

Depending on the design of the conveyor and the nature of the pressed material to be pressed, it can happen that parts, for example tines, pierce the conveyor into the pressed material. In order to ensure that the material to be compacted does not get caught on the conveying device, it is expedient for the conveying device to be assigned on its side facing the press a material to be pressed which separates the conveying device.

A contribution to a favorable and safe for the operator of the press handling is achieved in that preferably the press on its back has a feed opening for the mechanical transfer of the material to be pressed from the collection truck in the press room and that the press on its front for a removal of a Press bale has from the press room in an open position pivotable door. The removal of a press bale from the press can thus be done in a conventional manner by conventional presses, which contributes to a safe operation of the press by the operator.

Furthermore, a further feed opening is expediently provided in the front of the press above the door or in the upper part of the door, through which pressed material can be manually filled into the press room. This advantageously achieves that the press can be manually filled from the front through the further feed opening, as known to the operator of conventional presses, especially with small quantities and residual quantities of pressed material, for which the use of a collecting truck is not worthwhile. The additional feed opening is expedient with a private door or flap optionally closable and releasable.

The press itself can be designed differently. In order to achieve a particularly economical operation of the press, it may be expedient that an active charging device of the press is arranged between the conveyor and the press room. The active charging device ensures that the pressed material to be pressed removed from the collecting device from the collecting trolley is introduced under a certain pre-compaction and forcibly into the press, in particular the press room. Alternatively, it is also possible that the conveyor itself transports the pressed material to be pressed from the collection truck into the interior of the press.

As active loading device of the press, at least one rotor roller with conveyor tines is preferably arranged between the conveying device and the pressing space. The conveyor tines can cooperate for a reliable transport of the material to be pressed into the press room with a slotted guide surface, in the slots of the conveyor tines can dip. Alternatively, two be provided parallel, oppositely rotating rotor rollers, between which the material to be pressed is conveyed through.

A further embodiment of the press according to the invention is characterized in that the conveyor, the lifting device and the loading device are each equipped with a force demand sensor and that the press is assigned a control unit, the measurement signals of the power demand sensors can be fed and by means of the measured signals in accordance with the delivery device in that the lifting device and / or the loading device are variable in their performance and / or reversible in their working direction. In this way, the control unit can respond flexibly and as needed to specific operating situations that could lead to malfunctions. If, for example, the power requirement of a drive exceeds a certain limit, then the drive, in which the limit value is exceeded, as well as seen in Pressgutförderrichtung possibly previous drives in their performance reduced or even switched off and possibly reversed. If, for example, only too much power is required at the drive of the lifting device, then only this drive is reversed. If, for example, too high a force requirement occurs at the drive of the milling rollers, then both the drive of the lifting device is reversed and the drive of the milling rollers is switched off and the charging device then continues to run alone for a limited, predefinable period of time. Then, the drive of the milling rollers is first turned on again and its power requirement is measured. If the power requirement is now below the limit, then the drive of the lifting device is switched on again. If, for example, at the feeder too high a power requirement occurs, then both the drive of the lifting device and the drive of the milling rollers is switched off or reversed. The drive of the charging device can not only be reduced in power or switched off, but also reversed if necessary. After that, the drives are switched back on step by step. These circuits require that the drives of said aggregates, ie the charging device, the conveyor and the lifting device, are driven either via respective associated drive units or that the drives are decoupled from each other via appropriate technical means, such as adjustable clutches. Preferably, however, working with independent drives. In this way, upcoming overloads are detected early and appropriate countermeasures are automatically initiated. This ensures reliable operation of the press and disturbances or damage due to overloading are avoided, even if the press is operated by technically non-specialist personnel.

Further, it is proposed for the press according to the invention that in the press room, a press plate between a position above the rotor roller and a position below the rotor roller is movable, that the feed tines extend into the range of movement of the press plate and that the press plate at its edge facing the rotor roller passage slots for Having conveyor tines. The conveyor tines of the charging device can thus extend further into the pressing space and advantageously convey the material to be conveyed better and more effectively into the pressing space. Due to the passage slots in the edge of the pressure plate facing the rotor roller, the tines which protrude into its movement range do not disturb the pressing stroke and the return stroke of the pressure plate. The extent of the passage slots is expediently limited to such a degree that the pressing action of the press plate and its mechanical stability are not affected by the passage slots.

A further embodiment of the press is characterized in that a bale ejector is arranged in the press room, which is adjustable for ejecting a finished pressed and possibly hardened press bale from a basic position outside the range of movement of the conveyor tines of the rotor roller in a Auswerfstellung in the range of movement of the conveyor tines of the rotor roller in that the rotor roller is associated with a rotational position sensor and in that prior to ejection of the pressing bale, the rotor roller can be stopped in a rotational position in which its conveying tines assume a position which is collision-free relative to the bale ejector. In this press, the position of the feed tines of the loading device in its switched-off state can advantageously be selected so that the bale ejector does not collide in its movement plane with the tines of the loading device. For this purpose, the position of the rotor roller or the position of the tines of the rotor roller is interrogated and the stopping of the rotor roller is then carried out in the appropriate, with respect to the bale ejector collision-free rotational position of the rotor roller. The rotor roller can thus be approximated as far as possible just the pressing space.

The press according to the invention with one or more associated collecting trolleys is advantageous, for example, in large-scale shops, such as consumer markets or large supermarkets. Also in industrial production, where to accumulate and press residues to be obtained, the press according to the invention can be used with advantage.

The FIG. 1 shows a press 1, designed here as a baler, together with a coupled to its front collection cart 2 in a perspective view. The press 1 has in its interior a pressing space in which by means of a Kaftantriebes 14 a not visible here pressing plate is moved downwards and upwards.

Pressed material to be pressed is first collected at one or more locations remote from the stationary press 1 in the collection cart 2 or in several collection cars 2. When the collection cart 2 is filled, it is brought to the press 1 by the operator and coupled thereto. For precise position coupling serve two pairs of rail-like coupling guides 27, 37, which are each provided on the upper edge of two side walls 24 and on two side cheeks 33 of a conveyor 3 positioned above the collection cart 2 on the left and right. The coupling engagement is produced by the collection car 2 is retracted with its coupling guides 27 in the coupling guides 37 of the conveyor 3. By means of two bars 15 which act on the side walls 24 of the collecting truck 2 on the left and right and are connected to the front of the press 1 facing the collecting trolley 2, the collecting trolley 2 is fixed in its coupled position.

The conveyor 3 is here connected to the press 1 and forms part of the press 1. Under a in FIG. 1 visible cover 35 are here four mutually parallel rotating drivable milling drums, which will be described later. To drive the conveyor 3 is the left in FIG. 1 visible drive 34, here an electric motor with angular gear.

Furthermore belongs to the press 1 according to FIG. 1 a lifting device 4, which is arranged above the conveyor 3 and which is connected via the conveyor 3, as this, with the press 1. The lifting device 4 comprises a lifting frame 41 in which a lifting slide 42 can be moved vertically in the direction 40 upwards and vice versa. As drive 44 of the lifting device 4 is a top of the lifting device 4 arranged electric motor with a bevel gear and a shaft over which parallel to the lifting frame 41 left and right two V-belts or chains are guided vertically. With these, the lifting carriage 42 is connected to its vertical adjustment. In FIG. 1 For the most part, the lifting carriage 42 is covered by the rear wall 22 of the collecting trolley 2 which extends upwards. On its side facing the observer, the lifting carriage 42 has a plurality of hooks 46, here four hooks 46, which, in the state of the collecting trolley 2 coupled to the press 1, engage in correspondingly positioned receptacles 26 in the rear wall 22.

In the example according to FIG. 1 are the back wall 22 and a in FIG. 1 non-visible bottom 21 of the collecting cart 2 combined to form a bottom-wall element 21, 22 which is movable relative to the rest of the collection cart 2 in two rear wall guides 22 'in the vertical direction.

By activating the drive 44 of the lifting device 4 and by simultaneously activating the drive 34 of the conveyor 3, the wall-floor element 21, 22 moves upward, at the same time by means of the conveyor 3 in the collecting vehicle 2 befindliches pressed material removed from above and in a is conveyed substantially horizontally extending conveying direction in the press 1.

For easy transport of the collecting truck 2 are mounted on the underside mounted rollers 25, which may for example be designed as fixed castors and castors.

FIG. 2 the drawing shows the press 1 with the conveyor 3 and the lifting device 4 in the same view as in FIG. 1 , but now without a collection truck. At the side facing the viewer of the press 1, the conveyor 3 attached thereto is again recognizable together with the lifting device 4.

The conveyor 3 consists of the two side walls 33, in which a total of four milling rollers 31 are mounted with mutually parallel, horizontal axes of rotation. By means of the drive 34, the milling rollers 31 are set in rotation. The milling rollers 31 have on their outer circumference in each case a plurality of prongs or prongs, with which in the collection vehicle 2 befindliches pressed material can be detected and conveyed in the direction of the press 1. Left and right at the lower edge of the two side cheeks 33, the rail-shaped coupling guides 37 are visible for coupling with the collection truck 2.

The lifting device 4 consists of the lifting frame 41, which is formed by the two vertical, parallel to each other extending side rails. On the lifting frame 41 of the lifting 42 in the stroke direction 40 can be moved. At the side facing the observer, the lifting carriage 42 carries the four hooks 46 for coupling to the rear wall of the collecting trolley.

Below the conveyor 3, the two bars 15 are visible on the press 1, which serve to fix a docked collecting truck. On top of the press 1, the power drive 14 for the inside of the press 1 vertically movable press plate can be seen.

FIG. 3 shows the press 1 with collection cart 2, conveyor 3 and 4 lifting device FIG. 1 in a vertical longitudinal section. The collection cart 2 is here fixed on the bolt 15 and the not visible here coupling guides relative to the press 1. The floor-wall element 21, 22 is in engagement with the lifting device 4, here not via the hooks and receptacles described above, but, as a technical variant, via a folding lever 45, which is manually adjustable.

In the in FIG. 3 shown state, the bottom 21 of the collecting truck 2 is already raised by a certain way up in the direction of the lifting arrow 40 by means of the lifting device 4. At the same time by the in-service conveyor 3 with her here four parallel, in the same direction in terms of the rotation arrows shown rotating milling rollers 31 collected in the collection vehicle 2 in the collection chamber 20 Pressgut 5 taken from above from the collection truck 2 and in the conveying direction 30 to the press 1 promoted.

The tines of the milling rollers 31 are arranged so that the radii of the tines overlap, so the tines mesh with each other. For this purpose, the tines of adjacent milling drums 31 are arranged offset from one another as seen in the direction of the milling drum. Advantage of this arrangement is that, except for the last in the conveying direction 30 milling drum 31, no scrapers are needed to strip adhering to the tines Pressgut 5 when the tines turn back up, because the coming of the top of the tines in the conveying direction 30 next milling roller 31 take over this stripping. The horizontal offset of the tines is in FIG. 3 not to be recognized, but the overlapping radii are visible.

The press 1 here has an active charging device 12 in the form of a rotatably driven rotor roller. The individual pieces of the material to be pressed 5 are transferred from the conveyor 3 to the loading device 12, which conveys the material to be pressed 5 with an obliquely downward movement component in the pressing chamber 10 of the press 1. In the lower part of the pressing chamber 10 an already pressed part of the material to be pressed 5 is shown. A pressing stroke of the pressure plate 13 is carried out by means of the power drive 14 in each case when the pressing chamber 10 is filled with pressed material to be pressed 5. After the pressing stroke, the pressed material 5, as shown in the lower part of the pressing space 10, compacted and it can again new, still uncompressed material to be 5 is introduced into the upper region of the pressing chamber 10. In this way, the collected in the collection truck 2, too pressing material to be pressed 5 without any manual intervention and without a great deal of time completely mechanically transferred from the collection chamber 20 of the collection truck 2 via the conveyor 3 and the feeder 12 in the press 1 and compacted, pressed in particular to compact and set or wrapped press bales.

In FIG. 3 It can also be seen that the bottom 21 of the collecting carriage 2 has on its upper side a contour which is adapted to the contour of the downwardly facing side of the conveyor 3. In this way, a complete removal of the pressed material 5 is ensured from the collecting space 20 of the collecting truck 2.

After complete emptying of the collecting truck 2, the conveyor 3 is stopped and by reversing the lifting device 4, the bottom-wall element 21, 22 is lowered again down to the lowest position. In this position, the bottom 21 is in its collection position, in which the collection cart 2 can be used for the collection of pressed material 5 to be pressed. After loosening the latch 15, the collection cart 2 according to FIG. 3 are pulled away to the right of the press 1 under the conveyor 3 and the lifting device 4 and then brought back to a remote from the press 1 collection point for pressed material.

In FIG. 4 The drawing shows a collection cart 2 is shown in a perspective view obliquely from behind. The floor 21 and the rear wall 22, which are not visible here, form the interconnected floor-wall element 21, 22, which can be moved vertically as a unit in the rear wall guides 22 '. In the upper part of the rear wall 22, the four receptacles 26 for receiving the here only as individual parts indicated hooks 46 of the lifting device are visible. Towards its sides, the collection cart 2 is bounded by the two side walls 24, which form a fixed part of the collection cart 2. Towards the front of the collection cart 2 is limited by the front wall 23. Along the upper edge of the two side walls 24, the coupling guides 27 extend in the form of a respective rail. On its underside, the collection cart 2 has the rollers 25 for easy movement and movement of the collecting truck 2 between collection points and press. 1

In FIG. 5 the collection car 2 is shown disassembled into its individual parts, being left in FIG. 5 the two side walls 24 and the front wall 23 with the lower side Casters 25 are visible, which together form a structural unit. Right in FIG. 5 the bottom 21 and the associated rear wall 22 of the collecting truck 2 are shown. Under the bottom 21, the two side rear wall guides 22 'are shown. The floor 21 has a width and depth corresponding to the area between the side walls 24 and the front wall 23 in consideration of a sufficient play of movement. This ensures that everything in the collecting space 20 located pressed material 5 is taken when lifting the bottom 21 upwards without jamming in a space between the side edges and the front edge of the bottom 21 on the one hand and the side walls 24 and the front wall 23 on the other to be able to.

At the top of the edges of the two side walls 24, the rail-shaped coupling guides 27 are attached. These coupling guides 27 and the cooperating therewith on the side of the conveyor 3 coupling guides 37 may be formed differently, as shown by several examples above left in FIG. 5 is indicated. Suitably, all the illustrated examples of cooperating coupling guides 27 and 37 are designed so that they are designed with centering inlet slopes to facilitate the coupling of the collecting truck 2 to the press 1 and their conveyor 3.

In FIG. 6 are the conveyor 3 and the lifting device 4 without the press, however, shown together with a collecting cart 2 to be coupled.

The conveyor 3 corresponds to the previously described embodiment; Reference is made to the preceding description. The same applies to the lifting device 4th

Also, the collection car 2 corresponds to the previously described embodiment. In FIG. 6 is the collection car 2 a position immediately before coupling to the conveyor 3 or press. For this purpose, the coupling guides 27 are brought on the side of the collecting carriage 2 in opposition to the coupling guides 37 on the underside of the conveyor 3. From this position, the collection cart 2 can be pushed forward, the coupling guides 27 and 37 come into mutual engagement. After closing the bolt, not shown here then the collection car 2 is fixed.

The state with docked collection car 2 is in FIG. 7 shown. The coupling guides 27 and 37 are now in complete engagement with each other. At the same time is also the lifting 42, here by means of the folding lever 45, into engagement with the rear wall 22 of the collecting vehicle 2. By means of the lifting device 4, the bottom 21 is raised together with the rear wall 22 of the collecting truck 2 in the direction of the lifting arrow 40, which in the collecting cart 2 located, not visible here to be pressed compact material gradually detected by the conveyor 3 and continuously removed from above and fed to the press.

The FIG. 8 shows a modified embodiment of the invention with in particular a modified lifting device 4. In the lifting device 4 shown here, this is below the collecting truck 2 and lifts by means of an associated lifting drive 44 to the collection car 2 in total.

The conveyor 3 corresponds essentially to the previously described embodiment. Please note when executing according to FIG. 8 in that the conveyor 3 has such dimensions in width and depth that it fits into the collecting space 20 of the collecting cart 2 and that the collecting cart 2 is then still vertically movable relative to the conveyor 3. It should also be noted that the front wall 23 is formed so that it does not hinder the transfer of the pressed material 5 from the collecting space 20 of the collecting truck 2 in the conveying direction 30 to the press 1 when lifting the collecting carriage 2. In the example shown, the front wall 23 is designed as a relative to the other collection car 2 vertically displaceable wall, which does not join the lifting movement of the collecting truck 2 when it lifts, so shifts relative to the rest of the collection car 2 down. Thus, the upper edge of the front wall 23 always remains at such a low level that the transfer of the material to be pressed 5 can take place without interference. Alternatively, the front wall 23 may be designed as a folding or folding or rolling wall.

In the FIG. 8 By the way, the shown press 1 corresponds to the version already in FIG. 3 has been described.

The lifting device 4 here corresponds to the embodiment according to the previously described FIGS. 1 to 3 as well as 6 and 7.

Another embodiment of the invention is in the FIG. 10 shown. The press 1 is designed here as a so-called disc press, in which initially relatively narrow partial bales are produced, whereby they receive a particularly high density. From several of these partial pressed bales a complete pressed bale is then formed by tying together.

Different from the previous examples is also the conveyor 3, which is formed here from a single milling drum 31 with a relatively large diameter of approximately the horizontal depth of the collecting space 20 in the collection truck 2. The pressed material 5 detected by the milling drum 31 is gradually removed from above from the collecting trolley 2 and fed to the press 1 under a cover 35, which at the same time is in the form of a scraper 36.

In the example below FIG. 10 also the lifting device 4 is shown in a further embodiment. The lifting device 4 is here below the conveyor 3 between the press 1 and the collection cart 2. The bottom 21 of the collecting truck 2 is performed in different directions in the vertical direction. For moving the bottom 21 in the direction of the lifting arrow 40, a single lifting arm 42 'or an arrangement of several lifting arms 42' protrudes through one or more appropriately arranged, narrow slots in the front wall 23 into the collecting cart 2 and below the bottom 21. The lifting arms 42 'Are mounted on a lifting carriage 42, which immediately in front of the front wall 23 of the collecting truck 2 at one with the Press 1 and the conveyor 3 connected lifting frame 41 is vertically movable.

By means of a drive 44 from an electric motor with bevel gear, the shaft 47 'with the gears 47 can be set in rotation. At the side facing away from the viewer inner side of the rear wall 22 of the collecting truck 2, two parallel vertical racks 48 are mounted in juxtaposition to the gears 47, when engaging the collecting carriage 2 engage with the gears 47.

Above the conveyor 3 is here a locking device 15 visible, which is designed as a locking flap and located in FIG. 12 is in a raised release position. For this purpose, the locking device 15 is pivotable in total about a horizontal axis, which runs parallel to the milling rollers 31 along the front edge of the conveyor 3 facing away from the viewer. The pivotability of the locking device 15 is indicated by dashed arrows shown pivoting. Furthermore, the locking device 15 is pivotable in itself about a further horizontal axis. The locking device 15 has a locking bar 15.1, which can be pivoted by an operator between a locking position and a release position. By means of two toggle lever arrangements 15.2, the movement of the locking bar 15.1 is converted into a linear displacement movement of two slotted slides 15.3. The slides 15.3 are guided in inclined guides 15.4 and act when coupling and locking of the collecting truck 2 with two head bolts 15.5 together, as in FIG. 15 will be described in more detail.

When docked and locked by means of the locking device 15 collection cart 2 can be moved by switching the lifting device 4, the bottom wall element 21, 22 by means of the interaction of the gears 47 with the racks 48 together with befindlichem in the collecting space 20 pressing material, wherein at the same time Turned conveyor 3, this material to be pressed from the top of the collection cart 2 decreases and according to FIG. 12 to the left in the press room promotes the press, otherwise not shown.

FIG. 13 shows the in FIG. 12 shown elements in a vertical section with a view towards the in FIG. 12 right, away from the viewer side, now the collection car 2 is coupled. Top in FIG. 13 the conveyor 3 with its four milling rollers 31 and the cover 35 arranged above it is visible. In operation, the milling rollers 31 rotate in the viewing direction according to FIG. 13 counterclockwise, so that there is a conveying effect on the bottom of the conveyor 3 supplied material to be pressed from left to right.

The conveyor 3 takes the pressed material from the collection cart 2 from above and conveys it in the horizontal direction over the in FIG. 21 invisible feed device 12 forward into the press room 10. So that no pressed material falls out of the press room 10 to the front, the front side feed opening 11 'is suitably closed when machine loading the press room 10, as well as of course then the door 16 is closed.

FIG. 22 shows a loading device 12, a conveyor 3 and a lifting device 4 as parts of a press not shown here, together with a docked collection cart 2. The conveyor 3 is here connected to a feed side of the other press, not shown, which is left of the Must present collection cart 2. The feeder 12 is located at and partially even in the feed opening of the press.

The conveyor 3 here has four arranged below an upper cover 35 and between side walls 33, mutually parallel, rotatable milling rollers, whose axes of rotation are perpendicular to the plane of the drawing. The milling drums are in operation by a common drive 34 of electric motor and bevel gear in the same direction rotation, but with relatively different rotational speeds, displaceable. In this case, the milling drum, which is closest to the charging device 12, has the highest rotational speed, while the milling roller furthest away from the charging device 12 has the smallest rotational speed.

The collecting cart 2 has a rectangular bottom 21 and a rear wall 22, a front wall 23 and two side walls 24, which together define an upwardly open collecting space. The collection cart 2 is movable on rollers 25, wherein an operator can detect the collection cart 2 on a handlebar 28 and direct. The bottom 21 is connected to the rear wall 22 to a bottom-wall element 21, 22, which is guided in total in the vertical direction relative to the other collection car 2 slidably.

At the in FIG. 22 to the right-facing rear of collection car 2 and conveyor 3, the lifting device 4 is arranged. It consists here of a arranged in a vertical plane lifting frame 41 to which a concealed lifting here by means of a lifting drive 44 is vertically movable. The lifting carriage has in the direction of the collecting cart 2 protruding hooks 46, which are engageable with the collecting cart 2, more precisely with arranged on the rear wall 22 hook receivers 26, and out of engagement. If, as in FIG. 22 shown, the collection vehicle is coupled and the intervention is made, the bottom-wall element 21, 22 of the collecting 2 together with therein pressed material by means of the lifting drive 44 in the stroke direction 40 are moved upwards, wherein at the same time switched-conveyor 3 this pressed material from the top of the collection cart 2 decreases and according to FIG. 22 to the left in the press room promotes the press, otherwise not shown.

Further, the loading device 12, the conveyor 3 and the lifting device 4, preferably their drives 12.4, 34 and 44, each equipped with a force sensor not visible here, the e.g. the current consumption recorded. The press 1 is a not shown, preferably electronic, control unit assigned to the measurement signals of the power demand sensors can be supplied and by means of the supplied in accordance with the supplied measurement signals the charging device 12, the conveyor 3 and / or the lifting device 4 and their drives 12.4, 34 and 44th are changeable in their performance and / or reversible in their working direction. An impending overshoot detected by one or more force sensors may be counteracted by automatic control intervention before any damage is caused by reducing or completely shutting off one or more drives or reversing their direction of operation. After a certain period of time, the power of the respective drives can then be automatically increased again or switched back to the normal working direction in order to continue the filling of the pressing space.

FIG. 23 shows a press plate 13 and a rotor roller 12.1 as items of in FIG. 22 shown press, in a perspective view obliquely from above. The press plate 13 is in the press room of the press vertically downward and upward movable, wherein a pressing stroke is from top to bottom. In this case, the pressure plate 13 moves between a position above and a position below the rotor roller 12.1. In order to be able to convey as much as possible into the pressing space of the press by means of the rotor roller 12.1, conveying tines 12.2 of the rotor roller 12.1 protrude into the movement range of the pressure plate 13. In order to avoid a mutual collision and damage, the pressure plate 13 has at its the rotor roller 12.1 facing edge to match the conveyor tines 12.2 arranged passage slots 13 '. When the pressure plate 13 moves past the rotor roller 12.1 during its vertical movement, the conveying tines 12.2 projecting into the pressing space pass through the passage slots 13 'of the pressure plate 13 without colliding therewith. The rotor roller 12.1 of the charging device 12 can by this arrangement, in which it protrudes into the pressing space of the press, promote the pressed material with particularly high efficiency in the pressing space inside. Since the passage slots 13 'have only a relatively small depth and width, they do not affect the stability and pressing function of the pressure plate 13.

FIG. 24 shows the loading device 12 and a portion of the press plate 13 of the press in a vertical section which is perpendicular to the axis 12.3 of the rotor roller 12.1 of the charging device 12. As the FIG. 24 illustrates the rotor roller 12.1 immediately before and partially even in the feed opening 11 of the press, wherein the projecting feed tines 12.2 of the rotor roller 12.1 protrude into the press room 10. The pressure plate 10 vertically movable pressure plate 13 is currently in a position equal to the rotor roller 12.1. It is visible how one of the conveyor tines 12.3 passes through the associated passage slot 13 'of the pressure plate 13.

Above the rotor roller 12.1 a guide surface 12.5 can be seen, which is arranged at a small distance from the orbit of the outer tips of the conveyor tines 12.2 of the rotor roller 12.1. By provided on the left end of the guide surface 12.5 joint, the guide surface can be pivoted 12.5 and adjusted in their distance from the rotor roller 12.1, for example, by a mechanical or motorized adjustment means or by the conveyed pressed material itself against a biasing force, such as the force of one here illustrated spring. The guide surface 12.5 ensures a secure engagement of the conveyor tines 12.2 in the pressed material to be conveyed.

FIG. 25 shows in vertical section a complete press 1 with conveyor 3, lifting device 4 and loading device 12, together with a docked collection truck 2, where now, inversely as in FIG. 22 , the collection car 2 on the left and the press 1 on the right. Top in FIG. 25 the conveyor 3 with its four milling rollers 31 and the cover 35 arranged above it is visible. In operation, the milling rollers 31 rotate in the viewing direction according to FIG. 23 counterclockwise, so that a conveying effect on the bottom of the conveyor 3 results in supplied pressed material in a conveying direction 30 from left to right. The feeding device 12 facing, the last milling drum 31 is assigned a projecting between the cutting prongs scraper 36 which dissolves the zugeförderte pressed material from the last milling drum 31 to pass it reliably to the charging device 12.

To the right joins to the conveyor 3, the loading device 12, which is arranged immediately before and partially in a feed opening 11 of the press 1 shown here. The charging device 12 consists here of a occupied with conveyor tines, rotatably driven rotor roller 12.1, which transports the pressed material through the feed opening 11 of the press 1 in the press room 10. In the viewing direction according to FIG. 25 rotates the rotor roller 12.1 of the charging device 12 in operation in a clockwise direction, wherein pressed material transported between the top of the rotor roller 12.1 and the arranged above this guide surface 12.5 and is conveyed with an obliquely downwardly facing movement component in the pressing chamber 10.

Below the conveyor 3 is the docked collection cart 2, which is movable on its rollers 25. At his in FIG. 25 to the right-facing front of the collection cart 2 has a handlebar 28, which may extend over the two side walls 24. The bottom 21 and the rear wall 22 are combined to the bottom-wall element 21, 22 and jointly displaceable in the vertical direction. This shift is effected by means of the lifting device 4.

From the lifting device 4 is in FIG. 25 a part of the lifting frame 41 with the lifting drive 44 visible. The lifting device 4 is mechanically connected to the conveyor 3 and is supported by this. When the lifting device 4 is turned on, the bottom-wall element 21, 22 is moved together with in the collecting chamber 20 of the collecting 2 accumulated pressed material in the stroke direction 40 upwards. To lower the floor-wall element 21, 22 after emptying the working direction of the lifting device 4 is reversed.

In the right-facing front of the press 1 there is a door 16, through which a finished pressed bale can be removed from the press room 10 of the press 1. For this purpose, the press 1 has a bale ejector 17 of known per se, extending from a bottom portion of the pressing space 10 at its in FIG. 25 extends to the left rear wall upwards. When a pressed bale is finished pressed and optionally tied off within the pressing space 10, the door 16 is opened and the bale ejector 17 is actuated. The bale ejector 17 moves the pressed bales in the press room 10 at its rear side upwards and at the same time tilts them forward so that the pressed bale tilts out of the press room 10 through the opened door 16 by an angle of approximately 90 °. For a further transport of the press bale, for example, a pallet can be placed in front of the press 1 on which the pressed bale is tilted. After closing the door 16 and moving back the bale ejector 17 in its basic position can be fed again pressed material and pressed together in the press 1 to another pressed bales.

In the upper part of the press 1, a power drive 14 is arranged for the press chamber 10 vertically movable press plate 13, here in the form of a single or double piston-cylinder unit.

FIG. 26 shows in a partial vertical section of the loading device 12 together with a part of the bale ejector 17 FIG. 25 , It can be seen that the bale ejector 17 is in its activated, raised position in the range of movement of the conveyor tines 12.2 of the rotor roller 12.1. In order to reliably avoid a harmful collision between the bale ejector 17 and the rotor roller 12.1, the rotor roller 12.1 is associated with at least one rotational position sensor which detects the current rotational position of the rotor roller 12.1 and transmits it to a control unit. In accordance with the rotational position sensor, when the rotor roller 12.1 stops, the control unit ensures that it comes to a standstill in a specific rotational position with respect to its projecting conveyor tines 12.2. In this case, this particular rotational position is defined so that in her the conveyor tines 12.2 do not come into contact with the bale ejector 17, when it is moved from below when it is activated to eject a finished press bale.

Furthermore shows also the FIG. 26 , as the FIG. 24 , the axis 12.3 of the rotor roller 12.1 and the guide surface 12.5 arranged above it.

FIG. 27 Finally, the lifting device 4 of the press 1 shows FIG. 22 as a single part in a vertical section. The supporting part of the lifting device 4 forms a lifting frame 41, which is arranged in a vertical plane. A lifting slide 42 can be moved vertically upwards and downwards under the guidance of a slide guide 42 "on the lifting frame 41. The lift drive, which is not visible here, lying in front of the cutting plane, for example an electric motor or a hydraulic motor with a gear, is one of The toothed wheels 48.1 and 48.1 'are mounted one above the other vertically above and below the lifting frame 41 and an endless traction means 47.1, such as a roller chain, is guided over the two toothed wheels 48.1, 48.1'.

The lifting carriage 42 takes in FIG. 27 its lowest position and is connected only at its lower end with the traction means 47.1, so that there is a large displacement for the lifting carriage 42, which corresponds to the distance of the gears 48.1 and 48.1 'practically. On the lifting carriage 42 here two pairs of two protruding hooks 46 are mounted, which serve to be coupled with a collecting cart 2, more precisely with its vertically movable parts, such as the bottom-rear wall member 21, 22, into engagement according to FIG. 25 To move the material to be pressed in the collection truck 2 upwards in the direction of the conveyor 3 and the bottom-rear wall element 21, 22 to move back to the removal of the material to be pressed. Thereafter, the collection cart 2 can then be decoupled from the lifting device 4 and brought to a collection point for pressed material.
