Press with at least one docking and detachable collection truck

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 be fed to a central press, in particular baler. 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 collecting trolley is carried out either manually or mechanically. schinell supports. 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 2008/1 13465 A1, filled or the pressed material is inserted through the feed opening of a horizontal baler example in the press room. 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 offer from the relevant practice known solutions for horizontal balers, in which a collection cart is placed in a lifting and tilting 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 a press of the type mentioned is known. 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, in the case of flat layered 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 in accordance with the supplied measurement signals the conveyor 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 via corresponding technical means, such as adjustable clutches, are decoupled from each other. 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 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 it is adjustable that the rotor roller is associated with a rotational position sensor and that prior to ejection of the press bale, the rotor roller is haltable in a rotational position in which their feed tines occupy a position relative to the Ballenauswerfer collision-free position. 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.

FIG. 1 shows a press 1, here embodied as a baling press, together with a collection cart 2 coupled to its front side 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 first Under a visible in Figure 1 cover 35 here are four mutually parallel, rotatably driven milling drums, which will be described later. To drive the conveyor 3 is the left visible in Figure 1 drive 34, here an electric motor with angular gear.

Furthermore, belonging to the press 1 according to Figure 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, the lifting carriage 42 is covered for the most part by the rear wall 22 of the collecting trolley 2 extending 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, the rear wall 22 and a floor 21 of the collecting truck 2, not visible in FIG. 1, are combined to form a floor-wall element 21, 22 which is movable relative to the remaining collecting trolley 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.

Figure 2 of the drawing shows the press 1 with the conveyor 3 and the lifting device 4 in the same view as in Figure 1, but now without collection car. 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 collecting trolley 2, conveying device 3 and lifting device 4 from FIG. 1 in a vertical longitudinal section. The collection cart 2 is here via the bolt 15 and not visible here coupling guides relative to the press

1 fixed. 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 state shown in Figure 3, the bottom 21 of the collecting truck 2 is already lifted 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 the sense of the rotation arrows shown rotating milling rollers 31 in the collection vehicle 2 collected in the collection chamber 20 Pressgut 5 from above from the collection car

2 removed and conveyed in the conveying direction 30 to the press 1.

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 can not be seen in FIG. 3, but the intersecting radii are visible.

The press 1 here has an active charging device 12 in the form of a rotatably drivable 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.

It can also be seen in FIG. 3 that the bottom 21 of the collecting carriage 2 has a contour on its upper side which is adapted to the contour of the downward-pointing side of the conveying device 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 of the collection cart 2 can be moved according to Figure 3 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 Figure 4 of the drawing, a collection truck 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 Figure 5, the collection cart 2 is shown disassembled into its individual parts, wherein the left in Figure 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 Figure 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 indicated by several examples in the upper left in Figure 5. 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 Figure 6, the conveyor 3 and the lifting device 4 without the press, but 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 Figure 6, the collection cart 2 is 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 coupled collection cart 2 is shown in FIG. 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.

FIG. 8 shows a modified embodiment of the invention, with a modified lifting device 4 in particular. In the case of the lifting device 4 shown here, it is located below the collecting carriage 2 and, by means of an associated lifting drive 44, raises the collecting carriage 2 in its entirety.

The conveyor 3 corresponds essentially to the previously described embodiment. It should be noted in the embodiment according to Figure 8, that the conveyor 3 has such dimensions in their width and depth that it fits into the plenum 20 of the collecting cart 2 and that the collection 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.

Incidentally, the press 1 shown in FIG. 8 corresponds to the embodiment already described in FIG.

FIG. 9 shows an embodiment of the invention with a modified conveyor 3. In contrast to the previously described examples, the conveyor 3 is here formed by a circulating conveyor belt 31 ', which is provided with spring-loaded conveyor belt 31'. the tines 32 is occupied. By a drive not visible here, the conveyor belt 31 'in the direction of the conveying direction 30 can be set in motion. As a result, also located with this conveyor 3 befindliches in the collecting chamber 20 of the collecting cart 2 pressed material 5 from above and also provided here a feed device 12 in the press room 10 of the press 1 shown here only in a section. In this case, a wide conveyor belt 31 'corresponding to the width of the collecting space 20 can be used, or several narrower conveyor belts 31' can be provided side by side.

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

Another embodiment of the invention is shown in FIG. 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 of Figure 10 and 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.

The fixation of the collecting truck 2 relative to the press 1 also take appropriate coupling guides, which are not visible in Figure 10, and two attached between the press 1 in the collection truck 2 bolt 15th

Figure 1 1 shows an embodiment of the invention, in which the lifting device 4 is integrated into the collection cart The bottom 21 of the collecting truck 2 is guided vertically movable in the collecting space 20, for which a scissors 43 is disposed below the bottom 21 of the collecting truck 2 in this. To adjust the scissors 43 is a lifting drive 44 in the form of a pneumatic or hydraulic piston-cylinder unit. All walls 22, 23 and 24 of the collecting cart 2 can be fixedly arranged in this embodiment. At the upper edge of the rear side wall 24 shown in FIG. 11, one of the coupling guides 27 provided on the side of the collecting carriage 2 can be seen, which engages with an associated coupling guide of the conveying device 3 which is not visible in FIG. About the coupling guides here the collection car 2 is correctly coupled to the press 1 with its conveyor 3. To fix the position of the collecting truck 2 relative to the press 1, the bolts 15 are also used here again.

Above the collecting carriage 2, the conveyor 3 can be seen, which here corresponds to the embodiment according to the previously described Figures 1 to 3, 6 and 8.

On the left in FIG. 11, a part of the actual press 1 with the press room 10, the feed opening 11 with associated loading device 12, the press plate 13 and the associated power drive 14 can be seen.

On the underside, the collection cart 2 according to FIG. 1 also has four rollers 25 in order to be able to easily move the collection cart 2 from one location to another.

Also, with the lifting device 4 in the lower part of the collecting truck 2, the bottom 21 of the collecting truck 2 can be steadily raised in the stroke direction 40 to supply in the collecting chamber 20 located Pressgut 5 gradually the conveyor 3 with the conveyor rollers 31. The conveyor 3 takes the pressed material. 5 from the top and led it to the feeder 12 of the press 1, whereby the pressed material 5 enters the press room 10 of the press 1.

To supply the lifting drive 44 of the lifting device 4 in the collection truck 2 this can either have its own energy source, such as electric battery, or have a connection with which a power supply connection to the press 1 or another external source can be produced.

Figure 12 shows a conveyor 3 and a lifting device 4 as parts of a press, not shown here incidentally, together with a collecting trolley to be coupled 2. The conveyor 3 is here connected to the back of the press, not shown.

The conveyor 3 here has four arranged below an upper cover 35, mutually parallel, rotatable milling rollers 31 which are displaceable by a common drive 34 of the electric motor and bevel gear in the same direction rotation.

The collecting cart 2 has a rectangular bottom 21, which is not visible here, and a rear wall 22, a front wall 23 and two side walls 24, which together define an upwardly open collecting space 20. The collection cart 2 is movable on rollers 25, wherein an operator can detect the collection cart 2 on a rear handlebar 28 and direct. As can be seen from the drawing, the rear wall 22 is extended towards the other walls 23 and 24 at the top. In addition, 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 in two lateral rear wall guides 22 'slidably.

At the viewer facing the rear of the conveyor 3, the lifting device 4 is arranged, which consists of a horizontal and parallel to the milling rollers 31 extending shaft 47 'with two rotationally mounted gears 47 thereon. 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 in comparison with the gears 47, two parallel vertical racks 48 ange- brought, which arrive when coupling the collecting carriage 2 in engagement with the gears 47.

Above the conveyor 3 is here a locking device 15 visible, which is designed as a locking flap and which is located in Figure 12 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 the collecting truck 2 with two head bolts 15.5 together, as will be described in more detail in Figure 15.

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 switched conveyor 3 this material to be pressed from the top of the collection cart 2 decreases and according to Figure 12 to the left in the press room of the press, otherwise not shown promotes.

FIG. 13 shows the elements shown in FIG. 12 in a vertical section with a viewing direction on the side facing away from the observer in FIG. 12, wherein the collection cart 2 is now coupled. Above in Figure 13, the conveyor 3 with its four milling rollers 31 and the cover 35 arranged above it is visible. During operation, the milling rollers 31 rotate in the viewing direction according to FIG. 13 in the counterclockwise direction, so that a conveying action results on the material to be pressed fed from below to the conveyor 3 from left to right.

To the right of the conveyor 3 is followed by a loading device 12, which in or immediately before a loading opening of the here also in the Übri- gene not shown press is arranged. The charging device 12 consists here of a occupied with conveyor tines, rotatably driven rotor roller, which transports the pressed material through the feed opening of the press in the press room.

Below the conveyor 3 is the docked collection cart 2, which is movable on its rollers 25. For exact positioning of the collecting truck 2 relative to the conveyor 3 rail-shaped coupling guides 27 are arranged on the upper edge of the side walls 24, which cooperate with not visible here coupling guides on the conveyor 3 and are engaged. At its rear side pointing to the left in FIG. 13, the collection cart 2 has a push bar 28. The bottom 21 and the rear wall 22 are combined to form the bottom wall element 21, 22 and can be displaced together in the vertical direction. This shift is effected by means of the lifting device 4.

Of the lifting device 4 is one of the gears 47 with the associated shaft 47 'visible in Figure 13. The gear 47 is now in docked collection car 2 with the rack 48 into engagement, which is arranged on the inside of the rear wall 22 of the collecting truck 2. In the illustrated embodiment, the rack 28 is a portion of a roller chain, which is mounted on a vertically extending in or on the rear wall 22 extending profile 48 'and clamped and fixed at least at its two ends. Alternatively or additionally, the roller chain for forming the toothed rack 48 may also be connected at points or over its entire length to the rear wall 22, for example by welding to the profile 48 '. When the lifting device 4 is turned on, the gears 47 rotate to empty the collecting 2 in a clockwise direction, whereby the bottom-wall element 21, 22 is moved together with collected in the collecting chamber 20 of the collecting 2 compacted material on the racks 48 upwards. To lower the bottom-wall element 21, 22 after emptying, the direction of rotation of the gears 47 is reversed.

At the top left in Figure 13, the locking device 15 is visible, which is now in its locked position. For this purpose, the locking device 15 is pivoted downwards, whereby it engages behind the upper part of the rear wall 22 from above. In this locking position, the locking device 15 is locked by pivoting the locking bar 15.1. The locking device 15 further has two pressure rollers 49, which serve to keep the racks 48 in secure engagement with the gears 47. For this purpose, the pressure roller 49 in each case presses on the rear side of the profiles 48 'facing away from the toothed racks 48, on the front side of which the toothed rack 48 lies. When raising and lowering of the floor-wall element 21, 22 so runs respectively the rack 48 together with the profile 48 'between the gear 47 and pressure roller 49 up or down. To compensate for wear, the pressure rollers 49 are expedient adjustable. In this way, a permanently secure, backlash-free engagement of gears 47 and racks 48 is ensured

Figure 14 shows in the same representation as Figure 12, the conveyor 3 together with the collection cart 2, which is now in its Ankoppelposition, but not yet fixed. The locking device 15 is now pivoted overall downward, whereby the viewer facing the rear part with the latch bracket 15.1 now the upper part of the upwardly extended rear wall 22 of the collecting truck 2 and engages behind. By an indicated in dashed lines further pivotal movement of the rear part of the locking device 15, this is brought into its final locked position. In Figure 14, the head bolts 15.5 are still out of engagement with the slotted slides 15.3 of the locking device 15th

With regard to the further reference numbers in Figure 14, reference is made to the preceding description.

FIG. 15 shows in a view from the rear the locking device 15 in its locked position. In this locking position, the locking bar 15.1 is pivoted downwards by an operator, whereby the toggle lever arrangements 15.2 assume an extended, self-locking over-center division. At the same time the slotted slide 15.3 are moved down by the pivoting of the latch bracket 15.1, wherein the slots of the slide 15.3 engage behind the heads of the head bolt 15.5. By the inclined guides 15.4 the slide 15.3 are braced against the head bolt 15.5 in the axial direction at the same time. In this locking position, the locking device 15 is fixed in its position against the head bolt 15.5 and thus against the conveyor 3. Since the rear wall 22 of the Collecting cart 2, which is not shown here, is located between the locking device 15 and the conveyor 3, and the collection cart 2 is exactly positioned and fixed relative to the conveyor 3 with the locking device 15 located in the locked position.

FIGS. 16 to 21 show a further embodiment in which the toothed rods 48 of the lifting device 4 are not arranged on the collecting trolley 2 but on the conveyor device 3.

Figure 16 shows in a perspective view obliquely from behind the conveyor 3 with the associated lifting device 4, together with a collecting trolley to be coupled 2. The conveyor 3 is executed here again according to the previously described embodiment; Reference is therefore made to the preceding description in this regard.

At the rear of the conveyor 3 facing the observer in FIG. 16, the lifting device 4 is arranged. The lifting device 4 here also has two on a common shaft 47 'arranged gears, which are hidden in Figure 16 and therefore not visible. By means of the drive 44 of electric motor and bevel gear, the shaft 47 'is set in rotation. Furthermore, the lifting device 4 here comprises a lifting slide 42 which carries a rack 48 at its two lateral vertical edges. These racks 48 are in constant engagement with the gears on the shaft 47 '. The lifting carriage 42 comprises two horizontally extending first support strips 46 'which have obliquely upwardly pointing projections on their side to be coupled to the collecting trolley 2. By switching on the drive 44, the lifting carriage 42 can be moved with its support strips 46 'in the vertical direction up and down.

On the right in FIG. 16, the collecting trolley 2 to be coupled in is visible, in the collecting space 20 of which pressed material 5 to be pressed, for example packaging material, such as cardboard, etc., is collected. For exact positioning of the collecting truck 2 relative to the conveyor 3 and the lifting device 4, an operator leads the collection cart 2 on the handlebar 28 with the rollers 25 in two parallel rails 65 which are arranged and fixed on the floor of the installation space of the press. To facilitate the introduction of the rollers 25 into the rails 65, these have their starting position on the right in FIG. 16. rich in each case a funnel-shaped inlet slope. At the opposite end of the rails 65 each have a stop for the leading rollers 25th

As in the previously described embodiment of the invention are in the collection truck 2 of Figure 16 whose bottom 21 and rear wall 22 to a relative to the other collection car 2 vertically displaceable bottom wall element 21, 22 connected to each other. At the viewer facing the outside of the rear wall 22 are two mutually parallel, horizontal support strips 26 'attached, which have outwardly and obliquely downwardly facing projections. By inserting the collecting carriage 2 in the direction of the arrow below the conveyor 3, the first support strips 46 'of the lifting device 4 and the second support strips 46' of the collecting truck 2 in an immediately superposed, adjacent position relative to each other.

In FIG. 17, the parts of the press shown there are shown in the same representation as in FIG. 16, whereby the collecting carriage 2 is now coupled and the lifting carriage 42 together with the bottom-wall element 21, 22 is displaced upwards by a partial distance. In the coupled state, the leading rollers 25 of the collecting truck 2 are located at the stops on the left in Figure 17 end of the rails 65. In addition, now under the first support strips 46 'of the lifting device 4 under the second, hidden in Figure 17 support strips 26' on the rear wall 22 of the Collecting cart 2 and thereby carry the bottom wall element 21, 22 together with the pressing material located in the collecting space 20. The engagement between the first and second support strips 46 ', 26' is thus made in a technically simple manner for lifting the bottom-wall element 21, 22 simply by lifting the lifting plate 42 from its lowest position and vice versa by lowering the lifting 42nd lifted to its lowest position.

FIG. 18 shows the conveying device 3 with the lifting device 4 and the collecting trolley 2 from FIGS. 16 and 17 in a side view of the left side in FIG. 16 and FIG. 17. Above in Figure 18, the already described conveyor 3 is visible. Towards the left and thus in the direction of the press, which is otherwise not shown here, the feeding device 12 follows the conveying device 3. Right in Figure 18, the lifting device 4 with its drive 44 and the shaft 47 'and one of the gears 47 disposed thereon can be seen. The gear 47 is engaged with the rack 48, which is mounted on the profile 48 ', which forms part of the lifting carriage 42, which is movable in the vertical direction. On the back of the conveyor 3 pointing to the right in Figure 18, two vertically spaced pressure rollers 49 are arranged as part of the lifting device 4 on soft the profile 48 'with its side facing away from the rack 48 side during the movement of the lifting slide 42 up and down expires. By horizontal adjustment of the pressure rollers 49, a backlash-free engagement between gears 47 and racks 48 can be adjusted.

Below the conveyor 3 is the collection cart 2 with its rollers 25 in the rails 65. On its right in Figure 18 rear wall 22, the two second support strips 26 'are mounted, which cooperate with the two parallel first support strips 46' of the lifting 42. In the basic position of the lifting device 4 shown in FIG. 18, in which the lifting carriage 42 assumes its lowest position, the first supporting strips 46 'of the lifting device 4 lie slightly below the second supporting strips 26' on the rear wall 22 of the collecting carriage 2.

When the drive 44 of the lifting device 4, the gear 47 rotates for lifting the lifting plate 42 in a clockwise direction, whereby the first support strips 46 'in the lower side contact the second support strips 26' on the rear wall 22 of the collecting truck 2 arrive. By further movement of the lifting carriage 42 upwardly lift its support rails 46 'from the bottom 21 and rear wall 22 existing floor-wall element 21, 22 together with the collected in the collection truck 2 pressed material upwards, whereby the pressed material to the bottom of the conveyor. 3 is moved. The conveyor 3 can then remove the pressed material from above and promote the loading device 12 in the press room of the associated press.

After emptying the collecting cart 2, the lifting carriage 42 is lowered again by reversing the drive 44, wherein, together with the lifting carriage 42, the bottom wall element 21, 22 is lowered until the position according to FIG. 18 is reached again. The collection cart 2 can now be pushed by an operator by means of the handlebar 28 under the conveyor 3 out or pulled to collect again pressed material in the collection truck 2 at remote locations from the press.

FIG. 19 shows a plan view of a section of conveyor 3 and lifting device 4, the front edge region of the conveyor 3 and of the lifting device 4, which is on the right in FIG. 18, being visible from above.

With its side facing away from the rack 48 side, the rectangular profile 48 'abuts two pressure rollers 49 spaced apart in the vertical direction, of which only the upper one is visible in FIG. On the left in FIG. 19, a small part of the conveyor 3 is still visible.

Figure 20 shows a plan view of a press 1, which is arranged in a room 6 in a corner region of two mutually perpendicular walls 60 of the installation space 6. The press 1 has in its interior the pressing space 10, in which a pressing plate not visible here in the vertical direction can be moved by means of a power drive 14. The front of the press 1 has in Figure 20 to the left. At this front of the press 1 is a door 16, which is shown here opened. In this open position of the door 16, a pressed bale 50 produced in the press 1 can be removed from the press room 10, for example tilted forward onto a transport pallet. Above the door 16 is another feed opening 1 1 ', which in addition to the rear side, that is arranged in Figure 20 right side, the press 1, the machine feed serving feed opening 1 1 is provided. By the front further feed opening 1 1 ', an operator can manually insert pressed material into the press room 10 of the press 1, in particular residual quantities or small quantities, for which the use of the collecting truck 2 is not worthwhile.

In Figure 20 above the press 1, that is, at the left side, a collection cart 2 is shown, which is to be coupled to the press 1. The collection 2 gene here also has the rear wall 22, the front wall 23 and two side walls 24, which together with the bottom 21 form the plenum 20, in which pressed material can be collected at remote from the press 1 points. By moving the collecting cart 2 in the direction of the dashed arrow the rollers arranged on the underside of the collecting carriage 2 enter the rails 65. In these, the collection cart 2 is then forcibly guided directionally pushed completely under the conveyor 3. In this position, the lifting device 4 and the conveyor 3 can be activated to machine in the manner already described above, the floor-wall element 21, 22 on the support strips 46 ', 26' lift and pressed material from the plenum 20 by means of Conveyor 3 and the charging device 12 through the rear side feed opening 1 1 in the press room 10 of the press 1 to transport. The press 1 can advantageously be placed in a corner of the room with its rear side facing a wall 60 and with one of its lateral sides, here its right side, facing the other wall 60, close to the walls 60. The coupling and uncoupling of the collecting truck 2 takes place from the other lateral side of the press 1, here from its left side.

FIG. 21 shows the press 1 together with the conveying device 3 and the lifting device 4 and the collecting trolley 2 from FIG. 20 to be coupled in a front view. On the right in FIG. 21, the press 1 can be seen, wherein now the view of the front side of the press 1 falls. In this front side there is the door 16, through which a pressed bale can be removed from the press room 10 of the press 1. Above the door 16 or formed as part of the door 16, the further feed opening 1 1 'is provided, which is open here, so that the view falls into the interior of the pressing space 10. In the upper part of the press 1, the power drive 14 is arranged for the press room 10 vertically movable, non-visible press plate.

At the side facing away from the viewer back of the press 1, a part of the conveyor 3 and the lifting device 4 can be seen. Left of the press 1 is the docking collection truck 2, the rear wall 22 is turned away from the viewer here. An operator can push on the handlebar 28 the collecting cart 2 with its rollers 25 in the rails 65, as indicated by the dashed arrow. Thereafter, by means of the lifting carriage 42 with its first support strips 46 ', the floor-wall element 21, 22 of the collecting truck 2 together with the collected therein, to be pressed compact become. The conveyor 3 takes the pressed material from the collection cart 2 from above and conveys it in the horizontal direction on the not visible in Figure 21 feed device 12 forward into the press room 10. So that no pressed material falls forward out of the press room 10 is at mechanically loading the pressing space 10, the front-side charging opening 1 1 'appropriately closed, as well as of course then the door 16 is closed.

Figure 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 rest of the press not shown, which one left of the collection cart 2 must present. 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 shown in Figure 22, the collection trolley is coupled and the engagement is made, the bottom-wall element 21, 22 of the collecting truck 2 can be moved together with therein pressed material by means of the lifting drive 44 in the lifting direction 40 upwards, wherein simultaneously switched conveyor 3, this material to be pressed from the top of the collection cart 2 decreases and promotes according to Figure 22 to the left in the press room of 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 assigned to a preferably non-illustrated electronic control unit, the measurement signals of the power demand sensors can be fed and by means of the measuring signals supplied in accordance with the feed 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.

Figure 23 shows a press plate 13 and a rotor roller 12.1 as individual parts of the press shown in Figure 22, 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 mutual collision and damage, the pressure plate 13 has at its edge facing the rotor roller 12.1, matching the feed tines 12.2. Trittsschlitze 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 part of the press plate 13 of the press in a vertical section, which runs perpendicular to the axis 12.3 of the rotor roller 12.1 of the loading device 12. As FIG. 24 illustrates, the rotor roller 12.1 lies directly in front of, and in part even in, the feed opening 11 of the press, the projecting feed tines 12.2 of the rotor roller 12.1 projecting into the pressing space 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.

Figure 25 shows in vertical section a complete press 1 with conveyor 3, lifting device 4 and loading device 12, together with a docked collection cart 2, now, reversed as in Figure 22, the collection cart 2 left and the press 1 is right. Above in Figure 25, the conveyor 3 with its four milling rollers 31 and the cover 35 arranged above it is visible. In operation, the milling drums 31 rotate in the viewing direction according to FIG. 23 in the counterclockwise direction, so that a conveying effect acts on the bottom of the conveyor belt. dereinrichtung 3 supplied pressed material in a conveying direction 30 from left to right results. 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 located immediately before and partially in a feed opening 1 1 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 1 1 of the press 1 in the press room 10. In the viewing direction according to FIG. 25, the rotor roller 12.1 of the charging device 12 rotates clockwise during operation, wherein material to be pressed is transported between the upper side of the rotor roller 12.1 and the guide surface 12.5 arranged above it and conveyed into the pressing space 10 with a movement component pointing obliquely downwards.

Below the conveyor 3 is the docked collection cart 2, which is movable on its rollers 25. At its front side pointing to the right in FIG. 25, the collection cart 2 has a push bar 28, which can also 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.

Of the lifting device 4, part of the lifting frame 41 with the lifting drive 44 is visible in Figure 25. 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, which extends from a bottom portion of the pressing chamber 10 at its lying in Figure 25 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 the charging device 12 together with a part of the bale ejector 17 from 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, FIG. 26, like FIG. 24, also shows the axis 12.3 of the rotor roller 12.1 and the guide surface 12.5 arranged above it. Finally, FIG. 27 shows the lifting device 4 of the press 1 from 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 assumes its lowest position in FIG. 27 and is connected to the traction means 47.1 only at its lower end, so that a large displacement path results for the lifting carriage 42, which practically corresponds to the spacing of the gears 48.1 and 48.1 '. 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 Figure 25 to move the pressed material in the collection truck 2 upwards in the direction of the conveyor 3 and the bottom-rear wall element 21, 22 after the removal of the pressed material to move back down. Thereafter, the collection cart 2 can then be decoupled from the lifting device 4 and brought to a collection point for pressed material.
