Definitions
- the present invention relates to a channel baling press with the features of the preamble of claim 1 and a method with the features of the preamble of claim 14.
- Baling presses are generally used for compacting loose materials to be shaped into an advantageous shape for transportation and storage purposes.
- Various types of presses are known for the production of cuboid bales, namely box presses (English: two ram baler), in which a first press ram compresses the material into a press box and a second ram causes the pressed bale to be ejected into a binding device .
- the other type is that of a channel baler (English: single ram baler), in which a press ram presses the material to be pressed from a feed area into a bale channel. In this bale channel, the material to be pressed is compacted against bales that are already there.
- bale channel The friction of the existing bales in the bale channel creates the counter pressure required for compaction.
- the bales are delivered in the same direction in which the baling process takes place.
- the bale is tied when a predetermined length of the bale has been reached in the pressing direction.
- the material or compacted material to be compacted can vary greatly, from light, easy-to-compact materials such as recycled plastic waste and cardboard to those that are difficult to compact Materials such as old tires or scrap metal are sufficient.
- the degree of compaction and the tendency to re-expand the material vary greatly.
- the positioning of the compacted material in a formed bale can also vary. Materials that interlock with each other during the pressing process can form a very well-defined bale. Materials with round cross-sections that are difficult to compact tend to form unstable bales. For the latter reason, a so-called vertical tie-off is advantageous in channel baling presses, in which a number of parallel ties are created across the front end face in the pressing direction, the upper and lower long sides and the rear end face. This binding prevents material from falling out on the lower long side when the bale is lifted and moved.
- the terms "vertical” and “horizontal” in this context are not understood in a narrow sense, for example to mean a direction parallel to the gravity vector or orthogonal to the gravity vector. Rather, the directions referred to as vertical and horizontal are essentially to be understood in this sense, with the horizontal direction approximately corresponding to the course of the pressing direction, i.e. depending on the design and installation of the channel baling press also an angle of a few degrees, for example 2° to 10° inclination angle the horizontal can have.
- the vertical direction is also to be understood as having a tolerance range of a few degrees, for example 2° to 10° angle of inclination relative to the vertical.
- a vertical binding creates a loop of bandaging material around the bale, which runs in a vertical plane, the vertical plane being essentially spanned by the vertical direction and the pressing direction.
- the horizontal binding will be done accordingly generated in a horizontal plane that is spanned by the pressing direction and a horizontal oriented transversely to the pressing direction.
- the second bandaging device has automatic holding means and separating means that work depending on a control for holding and separating the bandaging material, the bandaging material of the horizontal binding can be separated depending on a control, kept ready and if necessary be connected again. Access for operating personnel to the corresponding assemblies is not required. The process can be done automatically and therefore quickly and safely. In particular, it is also possible to change the type of binding (cross binding or simple, vertical strapping) from one bale to the next bale.
- the cross connectors are preferably designed to have multiple tracks, in particular with three to five tracks.
- a holding means is provided for each track of the bandaging material and all holding means can be controlled and driven together, in particular synchronously.
- a particularly effective holding means which also withstands high tensile forces acting on the bandaging material, has a separate, in particular concave, abutment for each track and a matching, in particular wedge-shaped, clamping member. These are preferably hydraulically actuated.
- the channel baling press has a separate separating means for shearing off the bandaging material for each track, and these can also preferably be controlled and driven together, in particular synchronously. This makes the separation process particularly quick and reliable.
- the holding means does not work against the abutment, but deforms the bandaging material by pushing a region of the bandaging material into the abutment without strictly clamping or squeezing it between the clamping member and the abutment. In bandaging material such as steel wire, this deformation creates enough friction to generate sufficient holding force.
- the holding means and the separating means are driven by a common, in particular hydraulic, actuator. This simplifies control, especially when all holding means and all separating means are driven together.
- the bandaging material can be separated in spatial proximity to the holding means and kept there ready for the next horizontal strapping.
- the resulting amount of bandaging material to be discarded is thereby reduced.
- Guide means in particular deflection rollers, are provided on the same side of the bale channel in order to guide the respective strand of bandaging material so that it is grasped by the pulling device and can be pulled transversely to the pressing direction along the back of the finished bale across the press channel.
- the guide means can be moved essentially parallel to the pressing direction, i.e. parallel or at an acute angle.
- the guide means can also be arranged to be pivotable about an approximately vertical axis, so that the guide means can be moved between a first and a second position.
- the first and second positions are at a distance from each other in the conveying direction. It is irrelevant whether the positions are at a distance from one another across the conveying direction.
- the guide means can influence the strand guidance, for example in such a way that the strand comes into the effective area of the holding and separating means or is guided out of it.
- the automatic holding means and/or the automatic separating means can be moved substantially parallel to the pressing direction, i.e. parallel or at an acute angle. Then the strand of bandaging material held in the holding means and/or the intended separation point in the area of the bandaging device can be moved, for example, from a rest position to an operating position and back, for example in order to specifically feed the bandaging material to the pulling device.
- the bandaging material is, for example, in the form of a steel wire, which is kept in a left and a right strand for each track in relation to the pressing direction and is drawn off from a supply spool for this purpose.
- a drilling device is provided on the side of the channel baler opposite the holding means, in particular a drilling device with two driven drilling grippers or drilling hooks, namely a drilling hook which is closer to the press ram and upstream in the pressing direction and a drilling hook which is closer to the bale outlet and is downstream in the pressing direction for each track the horizontal bandaging device.
- the drill hooks of the second, horizontal bandaging device can be driven separately, preferably all upstream drill hooks together and/or synchronously, and all downstream drill hooks also together and/or synchronously.
- a second separating device can be arranged between an upstream twisting hook and a downstream twisting hook.
- a strand of the bandaging material is separated by means of a separating device and one end of the separated strand is in a holding device until further use is held, whereby the holding is effected by deforming the strand, the separating and holding process can be carried out automatically and in particular the resulting free end of the strand can be held in a suitable, defined position until it is captured and used again in a later bandaging process becomes. This ensures that the free end is not in undefined locations within the channel baling press.
- the Figure 1 shows part of a channel baling press in a top view.
- the illustration is a schematic sectional view in a longitudinal section parallel to a pressing direction P.
- the drawing plane is a horizontal plane of the device, which is spanned by the pressing direction P and a transverse direction Q oriented at right angles to the pressing direction P.
- the channel baling press has an input area 1, not shown, into which material to be pressed is to be entered loosely.
- a hydraulic unit 2 is provided to move a press ram 3 from the input area 1 into a bale channel 4 and thereby compress the material to be pressed there.
- Several working strokes of the press ram 3 produce a bale 5.
- a bandaging device Seen in the pressing direction P, a bandaging device with several components is provided in a downstream area of the bale channel 4, approximately where the working stroke of the hydraulic unit 2 ends, which are essentially known from the prior art.
- the bandaging device specifically comprises a left supply spool 10 in this illustration and a right supply spool 11.
- the two supply spools 10 and 11 hold a bandaging material in the form of a quasi-endless steel wire for strapping the bales produced.
- a left strand 12 of the bandaging material runs from the supply spool 10 through a left guide means 13, which is formed by two deflection rollers and the wire to a wire entry, not shown of the bale channel 4.
- a right strand 14 runs from the supply spool 11 to a right guide means 15, which also has two deflection rollers and leads the wire to a right wire entry of the bale channel.
- a connecting device 17 is arranged in the area of the guide means 13 and 15, which in this case is designed as a twisting device due to the use of steel wire. This device is described in more detail below. What is important here is that the connecting device 17 includes a first twist hook 18 and a second twist hook 19, each of which can be driven separately.
- the first drill hook 18 is driven by a first drive 20 to rotate about a horizontal axis of rotation which is oriented parallel to the transverse direction Q.
- the second drill hook 19 is driven by a second drive 21 about a corresponding parallel axis of rotation. Both drives 20, 21 are controlled by a control 22, which is only shown schematically.
- the connecting device 17 further comprises a drawing needle 23, which can be moved parallel to the transverse direction Q by a drive 24 depending on the control 20.
- the design of the drawing needle 23 is known from the prior art.
- the guide means 15 is arranged on an actuator 25, which is set up to move the guide means 15 parallel to the pressing direction P not far from the control 20.
- the actuator 25 can in particular be driven hydraulically.
- the right strand 14 of the bandaging material runs between the guide means 15 and the bale channel 4 via a combined holding and separating means 26, which is not shown in more detail here.
- the combined holding and separating means 26 is also hydraulically actuated and has a concave, fixed abutment and a movable, matching wedge-shaped clamping element, between which the bandaging material can be clamped and held.
- a release agent in the form of a shearing device is also provided.
- a first bale 5 is completely produced and compacted.
- the pressing pressure, with which the bale 5 was compacted is maintained by the hydraulic unit and the press ram 3 in order to prevent the bale 5 from expanding back as long as it is not yet strapped or bandaged.
- the bale 5 automatically took bandaging material with it, namely removed from the left supply spool 3 and the right supply spool 11.
- the strand 12 rests on the left side of the bale 5 in the pressing direction P.
- the strand 14 rests on the side leading in the pressing direction P and on the right side of the bale 5.
- a twist 28 which was previously generated by the connecting device 17, the two strands 12 and 14 are connected to one another in a tension-resistant manner.
- the Figure 2 shows that based on the operating state in Figure 1 the drawing needle 23 and in the drive 24 are moved in the transverse direction into the bale channel 4, more precisely into a horizontal groove 29 of the press ram 3.
- the Figure 3 shows how the drawing needle 23 has moved to its right end position.
- One end 30 of the drawing needle 23 has been moved between the right guide means 15 and the combined holding and separating means 26 and under the strand 14 located there into an extreme right position (relative to the pressing direction P).
- the end 30 of the drawing needle 23 has a head, which is not shown in detail here.
- the head essentially comprises a catching element in the manner of a barb and a roller over which the strand 14 can roll.
- the channel baling press illustrated here is intended to provide the option of choosing whether the bale produced should be tied horizontally or not, and to automatically carry out the necessary steps for this. It should also be mentioned that a conventional vertical tying, which is not shown in the figures, is present in this channel baling press and that it is always active.
- the bales produced are either strapped vertically and horizontally, as with the bale 5 shown here, or only strapped vertically when the horizontal strapping is switched off.
- the Figure 6 now shows the process step that is carried out if the next, not yet produced bale is to be produced without horizontal bandaging.
- this step only the downstream twisting hook 19 has been driven and has grasped and twisted the strands 12 and 14 extending from the bale downstream of the pulling needle 23, so that the bale 5 is completely wrapped around with a second twist 28 'and secured against re-expansion.
- a separating device assigned to the connecting device 17 then severed the two strands 12 and 14, so that the bale 5 is free of the virtually endless strands 12 and 14 and can be dispensed.
- the actuator 25 is controlled in order to move the guide means 15 parallel to the pressing direction P into a downstream end position. This movement causes the free end of the right strand 14 to be pulled out of the upstream twist hook 18. It lies loosely in the groove 29 of the press ram 3.
- the strand 14 is also brought closer to the combined holding and separating means 26.
- the holding and separating means 26 is now closed by vertically advancing the clamping element, not shown, whereby the strand 14 is clamped and held.
- the free end of the strand 14 lying in the groove 29 is separated from the associated separating device close to the holding means 26 and is present as a section 31. This section 31 is discarded in the further process in which it is processed in the subsequently produced bale.
- the Figure 9 shows the tying device of the channel baling press in the same condition as that Figure 8 .
- another bale 35 has been produced in the bale channel 4. Since the left strand 12 and the right strand 14 are currently not connected to each other, none of the strands 12, 14 were taken along by the bale 35.
- the bale 35 is not strapped horizontally, but only vertically.
- the discarded section 31 lies at the front in front of the bale 35 and is strapped together with the bale 35 by the vertical bandaging.
- the channel baling press is now prepared for the horizontal strapping of the next bale.
- the Figure 12 shows how the drawing needle 23 grasps the right strand 14 with its head 30 and takes it into the groove 29 in the backward movement.
- the strand 14 is pulled off the right supply spool 11.
- the free end remains fixed in the combined holding and separating means 26.
- Figure 14 shows that this created a twist 36, which firmly connects the left strand 12 and the right strand 14 train.
- the piece of the right strand 14 located between the pulling needle 23 and the combined holding and separating means 26 is then separated from the separating device of the connecting device 17, the clamping device is released and the separated wire is now present as a section 37 in the groove 29. This section 37 is again rejected.
- the Figure 15 finally shows how a third bale 45 was produced, through which the non-horizontally strapped bale 35 was transported further in the pressing direction in the bale channel 4.
- the third bale 45 in the sequence shown has in turn taken along the two strands 12 and 14 connected to one another in the twist 36.
- the channel baler is now in the condition of Figure 1 .
- the bale can now be strapped completely horizontally.
- the controller 22 can also make this decision itself, for example through comparison specified parameters of the bales 5, 35 and 45 produced depending on target values.
- the pulling needle starts from Figure 15 the right strand 14 and the left strand 12 between the two twist hooks 18 and 19 (as in Fig. 2 to 5 shown). Then the twist hooks 18 and 19 are controlled simultaneously, so that two twists are created, between which the strands 12 and 14 are then separated. Then one twist remains with the bale 45 and closes its horizontal bandaging, while the next twist is taken from the leading side of the bale that is still to be produced and becomes the starting point for the next horizontal strapping.
- bale following the bale 45 is not to be strapped, then the procedural steps are as described above using the Figures 2 to 15 carried out as described.
- the connecting device 17 in a horizontal front view from the in Figure 1 shown on the right side, i.e. from the side on which the bale channel 4 is located.
- the connecting device 17 includes a housing 46, which carries the two drives 20 and 21 on its top.
- Three groups of twist hooks 18 and 19 are arranged on the visible end face and are rotatably mounted in the housing 46.
- a total of three pairs of twist hooks 18 and 19 arranged one above the other are provided, since the connecting unit 17 is intended for three parallel tracks of bandaging.
- the pulling needle 23 of each track can be seen between the drill hooks 18 and 19, with a view here of the frontal free end 30, which during operation, for example Figure 3 takes hold of strand 14 and pulls it.
- Strand 14 runs as in Figure 16 can be seen behind a roller 47 which is arranged in the head 30 of the drawing needle 23 to reduce friction.
- a separating device 48 which is also designed in triplicate, with an actuator 49, a movable knife bar 50, which carries three knives 51, and three stationary ones Counter knives 52.
- the twist hooks 18 and 19 grasp and twist the strands 12 and 14 either synchronously, as is required for the horizontal strapping of successive bales.
- the drill hooks 18 and 19 can also be driven individually, since, in contrast to the prior art, two separate drives 20 and 21 are provided, each of which is assigned to a group of drill hooks 18 and 19, respectively.
- the Figure 17 shows the connection device 17 Figure 16 , whereby not all reference numbers are repeated.
- the actuator 49 of the separating device 48 has been activated and moves the knife bar 50 upwards, so that the knives 51 are moved against the stationary knives 52 and shear off the material strands 12 and 14 lying between the two knives.
- the Figure 17 corresponds to the state of the connecting device 17 in Figure 6 .
- bales with horizontal tying to bales without horizontal tying and vice versa can be carried out automatically by the control at the operator's discretion. With appropriate sensors and programming, autonomous automatic switching can even take place without operator intervention.
- Figure 18 shows the holding means 26 described above in an enlarged view in a view in which the pressing direction (P) is perpendicular to the drawing level stands. Only the holding means 26 of a track of the bandaging device is shown.
- the holding means 26 comprises a concave abutment 60, which has two plates 61 and 62 mounted at a distance from one another, and a clamping member 63, which is also plate-shaped.
- the strand 14 lies between the abutment 60 and the clamping member 63 as a wire presented by the guide means 15. In the open position Fig. 18 , those described above Figure 1 corresponds, the strand 14 does not rest on the abutment 60 or only at points.
- the plates 61 and 62 are mounted upright and each have a top side 65 and 66 pointing towards the clamping member 63.
- the top sides 65 and 66 of the plates 61 and 62 are rounded.
- the clamping member 63 is designed in a similar plate-like manner and has an underside 67 pointing towards the abutment 60, the clamping member 63 being positioned approximately centrally between the plates 61 and 62 transversely to the pressing direction P.
- the distance a of the plates 61 and 62 from one another, defined by an intermediate piece 67, is significantly larger than the thickness of the clamping member 63.
- the top of the plate 61 is straight in the pressing direction P and is therefore essentially horizontal during operation.
- the top of the plate 62 is not straight, but has an upward projection 68 facing the viewer, which points upward like a pin or a fin. In the viewing direction behind the projection 68, the top 66 of the plate 62 jumps down approximately to the level of the adjacent top 65 of the plate 61.
- the Figure 18 also shows the separating means that is assigned to this holding device. It comprises a movable knife 70 and a counter-knife 71.
- the knife 70 is mounted movably together with the clamping member 63 in a direction of movement B, while the counter-knife 71 is firmly mounted on the frame of the abutment 60.
- Figure 19 shows the components Figure 18 in a position in which an actuator pushes the clamping member 63 down between the plates 61 and 62 has moved and thereby pushed the wire of the strand 14 into the concave area of the abutment 60 and thereby deformed it.
- the guide means 15 has placed the strand 14 around the projection 68 under tension.
- the strand 14 has been severed by the knife 70 and the counter knife 71 on the side of the abutment 60 facing away from the projection 68. This position corresponds to the position of the holding and separating means 26 in Figure 8 .
- the section 31 described there is the part of the strand 14 which is separated in the manner described from that in Figure 19 visible part of the strand 14 was separated and discarded.
- the position of the knife 70 and the clamping member 63 in the direction of movement B is selected such that first the clamping member 63 together with the abutment 60 creates a clamping effect and then the knife 70 cuts the strand 14 with the counter knife 71.
- a chronological sequence of these process steps is achieved with a common actuator.
- the distance a between the plates 61 and 62 is greater than the sum of the thickness of the clamping member 63 transverse to the direction of movement B and twice the thickness of the strand 14. This ensures that the in Figure 19 Deformation shown ensures that the strand 14 is well fixed before and after the separation and that the strand is not clamped or squeezed and the movement of the clamping member 63 does not take place against a stop. This is advantageous for reliable actuation of the knife 70, which can always perform the full intended stroke, even if it is actuated by the same actuator as the clamping member 63.

Description
Die vorliegende Erfindung betrifft eine Kanalballenpresse mit den Merkmalen des Oberbegriffs des Anspruchs 1 und ein Verfahren mit den Merkmalen des Oberbegriffs des Anspruchs 14.The present invention relates to a channel baling press with the features of the preamble of
Ballenpressen werden im Allgemeinen zur Verdichtung von losen Materialien eingesetzt, die zu Transportzwecken und Lagerzwecken in eine vorteilhafte Form gebracht werden sollen. Für die Fertigung von quaderförmigen Ballen sind verschiedene Bauformen von Pressen bekannt, nämlich einmal Kastenpressen (englisch: two ram baler), bei denen ein erster Pressstempel die Verdichtung des Materials in einen Presskasten vornimmt und ein zweiter Stempel den Ausschub des gepressten Ballens in eine Abbindevorrichtung bewirkt. Die andere Bauart ist die einer Kanalballenpresse (englisch: single ram baler), bei der ein Pressstempel das Pressgut aus einem Aufgabebereich in einen Ballenkanal presst. In diesem Ballenkanal wird das Pressgut gegen dort bereits vorhandene Ballen verdichtet. Die Reibung der vorhandenen Ballen im Ballenkanal bewirkt den zur Verdichtung erforderlichen Gegendruck. Am Ende des Ballenkanals werden die Ballen in derselben Richtung ausgegeben, in der der Pressvorgang erfolgt. Das Abbinden des Ballens erfolgt, wenn eine vorgegebene Länge des Ballens in Pressrichtung erreicht ist.Baling presses are generally used for compacting loose materials to be shaped into an advantageous shape for transportation and storage purposes. Various types of presses are known for the production of cuboid bales, namely box presses (English: two ram baler), in which a first press ram compresses the material into a press box and a second ram causes the pressed bale to be ejected into a binding device . The other type is that of a channel baler (English: single ram baler), in which a press ram presses the material to be pressed from a feed area into a bale channel. In this bale channel, the material to be pressed is compacted against bales that are already there. The friction of the existing bales in the bale channel creates the counter pressure required for compaction. At the end of the bale channel, the bales are delivered in the same direction in which the baling process takes place. The bale is tied when a predetermined length of the bale has been reached in the pressing direction.
Die Begriffe "Abbinden", "Umreifen" und "Bandagieren" werden in diesem Fachgebiet synonym benutzt.The terms “tying off”, “strapping” and “bandaging” are used synonymously in this field.
Das zu verdichtende Material oder Pressgut kann sehr unterschiedlich sein und von leichten, leicht zu verdichtenden Materialien wie Recycling-Kunststoffabfällen und Kartonagen bis hin zu schwer zu verdichteten Materialien wie Altreifen oder Metallschrott reichen. Dabei sind der Verdichtungsgrad und auch die Neigung zur Rückexpansion des Materials sehr unterschiedlich. Auch die Haltung des verdichteten Materials in einem geformten Ballen kann unterschiedlich sein. So können Materialien, die im Pressvorgang miteinander verzahnen, einen sehr gut definierten Ballen bilden. Materialien mit eher runden Querschnitten, die sich wenig verdichten lassen, bilden eher instabile Ballen. Aus letzterem Grund ist bei Kanalballenpressen eine sogenannte Vertikalabbindung vorteilhaft, bei der eine Anzahl von parallelen Abbindungen über die in Pressrichtung vordere Stirnseite, die obere und die untere Langseite und die hintere Stirnseite erzeugt wird. Diese Abbindung verhindert, dass an der unteren Langseite beim Anheben und Bewegen des Ballens Material ausfällt.The material or compacted material to be compacted can vary greatly, from light, easy-to-compact materials such as recycled plastic waste and cardboard to those that are difficult to compact Materials such as old tires or scrap metal are sufficient. The degree of compaction and the tendency to re-expand the material vary greatly. The positioning of the compacted material in a formed bale can also vary. Materials that interlock with each other during the pressing process can form a very well-defined bale. Materials with round cross-sections that are difficult to compact tend to form unstable bales. For the latter reason, a so-called vertical tie-off is advantageous in channel baling presses, in which a number of parallel ties are created across the front end face in the pressing direction, the upper and lower long sides and the rear end face. This binding prevents material from falling out on the lower long side when the bale is lifted and moved.
Gerade bei den schwierig zu verdichteten Materialien mit hoher Neigung zur Rückexpansion kann es auch vorteilhaft sein, sowohl eine vertikale Abbindung als auch eine horizontale Abbindung vorzusehen, damit auch die seitlichen Langseiten des Ballens umreift werden. Es wird dann von einer Kreuzabbindung gesprochen.Especially with materials that are difficult to compact and have a high tendency to expand back, it can also be advantageous to provide both a vertical tie and a horizontal tie so that the long sides of the bale are also strapped. This is then referred to as a cross binding.
Der Fachmann weiß, dass die Begriffe "vertikal" und "horizontal" in diesem Zusammenhang nicht im engen Sinne verstanden werden, etwa derart, dass eine Richtung parallel zum Schwerkraftvektor bzw. orthogonal zum Schwerkraftvektor gemeint ist. Vielmehr sind die als vertikal und horizontal bezeichneten Richtungen im Wesentlichen in diesem Sinne zu verstehen, wobei die Horizontalrichtung etwa dem Verlauf der Pressrichtung entspricht, also je nach Bauart und Installation der Kanalballenpresse auch einen Winkel von einigen Grad, beispielsweise 2° bis 10° Neigungswinkel gegenüber der Horizontalen aufweisen kann. Entsprechend ist auch die Vertikalrichtung mit einem Toleranzbereich von einigen Grad, beispielsweise 2° bis 10° Neigungswinkel gegenüber der Vertikalen zu verstehen. Eine Vertikalabbindung erzeugt in diesem Sinne eine Schlaufe aus Bandagiermaterial um den Ballen herum, die in einer Vertikalebene verläuft, wobei die Vertikalebene im Wesentlichen von der Vertikalrichtung und der Pressrichtung aufgespannt ist. Die Horizontalabbindung wird dementsprechend in einer horizontalen Ebene erzeugt, die von der Pressrichtung und einer quer zur Pressrichtung orientierten Horizontalen aufgespannt wird.The person skilled in the art knows that the terms "vertical" and "horizontal" in this context are not understood in a narrow sense, for example to mean a direction parallel to the gravity vector or orthogonal to the gravity vector. Rather, the directions referred to as vertical and horizontal are essentially to be understood in this sense, with the horizontal direction approximately corresponding to the course of the pressing direction, i.e. depending on the design and installation of the channel baling press also an angle of a few degrees, for example 2° to 10° inclination angle the horizontal can have. Correspondingly, the vertical direction is also to be understood as having a tolerance range of a few degrees, for example 2° to 10° angle of inclination relative to the vertical. In this sense, a vertical binding creates a loop of bandaging material around the bale, which runs in a vertical plane, the vertical plane being essentially spanned by the vertical direction and the pressing direction. The horizontal binding will be done accordingly generated in a horizontal plane that is spanned by the pressing direction and a horizontal oriented transversely to the pressing direction.
Während die Kreuzabbindung oder Kreuzumreifung auch bei schwierig zu handhabenden Materialien eine robuste Abbindung des Ballens gewährleistet, ist sie doch bei einfachen Materialien nicht erforderlich. Es ist deshalb vorteilhaft, wenn die Horizontalabbindung im Bedarfsfall zugeschaltet und abgeschaltet werden kann. Eine manuelle Außerbetriebnahme und Inbetriebnahme der horizontalen Abbindung ist schwierig und zeitaufwändig, weil dazu Bedienpersonal in den Sicherheitsbereich der Kanalballenpresse gelangen muss und die Kanalballenpresse deshalb für diesen Vorgang jeweils außer Betrieb genommen werden muss.While cross binding or cross strapping ensures robust binding of the bale even with difficult-to-handle materials, it is not necessary for simple materials. It is therefore advantageous if the horizontal binding can be switched on and off if necessary. Manual decommissioning and commissioning of the horizontal tying is difficult and time-consuming because this requires operating personnel to get into the safety area of the channel baling press and the channel baling press must therefore be taken out of operation for this process.
Es ist deshalb Aufgabe der vorliegenden Erfindung, eine Kanalballenpresse zu schaffen, bei der eine Kreuzabbindung mit automatisch abschaltbarer und zuschaltbarer horizontaler Abbindung vorgesehen ist.It is therefore the object of the present invention to create a channel baling press in which cross tying is provided with horizontal tying that can be switched on and off automatically.
Diese Aufgabe wird von einer Kanalballenpresse mit den Merkmalen des Anspruchs 1 gelöst.This task is solved by a channel baling press with the features of
Weil bei einer gattungsgemäßen Kanalballenpresse mit Kreuzabbindung weiter vorgesehen ist, dass die zweite Bandagiereinrichtung automatische, in Abhängigkeit von einer Steuerung arbeitende Haltemittel und Trennmittel zum Halten und Trennen des Bandagiermaterials aufweist, kann das Bandagiermaterial der Horizontalabbindung in Abhängigkeit von einer Steuerung aufgetrennt, bereitgehalten und bei Bedarf wieder angebunden werden. Ein Zugang von Bedienpersonal zu den entsprechenden Baugruppen ist nicht erforderlich. Der Vorgang kann automatisch und damit schnell und sicher erfolgen. Es ist insbesondere auch möglich, die Art der Abbindung (Kreuzabbindung oder einfache, vertikale Umreifung) von einem Ballen zum nächsten Ballen zu wechseln.Because in a generic channel baling press with cross binding it is further provided that the second bandaging device has automatic holding means and separating means that work depending on a control for holding and separating the bandaging material, the bandaging material of the horizontal binding can be separated depending on a control, kept ready and if necessary be connected again. Access for operating personnel to the corresponding assemblies is not required. The process can be done automatically and therefore quickly and safely. In particular, it is also possible to change the type of binding (cross binding or simple, vertical strapping) from one bale to the next bale.
Die Querverbringer sind bevorzugt mehrspurig ausgebildet, insbesondere mit drei bis fünf Spuren versehen.The cross connectors are preferably designed to have multiple tracks, in particular with three to five tracks.
Insbesondere ist es von Vorteil, wenn für jede Spur des Bandagiermaterials ein Haltemittel vorgesehen ist und alle Haltemittel gemeinsam, insbesondere synchron, ansteuerbar und angetrieben sind.In particular, it is advantageous if a holding means is provided for each track of the bandaging material and all holding means can be controlled and driven together, in particular synchronously.
Ein besonders wirksames Haltemittel, das auch hohen auf das Bandagiermaterial wirkenden Zugkräften widersteht, weist für jede Spur ein separates, insbesondere konkaves Widerlager und ein dazu passendes, insbesondere keilförmiges Klemmglied auf. Diese sind vorzugsweise hydraulisch betätigbar.A particularly effective holding means, which also withstands high tensile forces acting on the bandaging material, has a separate, in particular concave, abutment for each track and a matching, in particular wedge-shaped, clamping member. These are preferably hydraulically actuated.
Weiter ist es von Vorteil, wenn die Kanalballenpresse für jede Spur ein separates Trennmittel zum Abscheren des Bandagiermaterials aufweist, und diese weiter bevorzugt auch gemeinsam, insbesondere synchron, ansteuerbar und angetrieben sind. Dadurch wird der Trennvorgang besonders schnell und zuverlässig durchführbar.It is also advantageous if the channel baling press has a separate separating means for shearing off the bandaging material for each track, and these can also preferably be controlled and driven together, in particular synchronously. This makes the separation process particularly quick and reliable.
In einer besonders bevorzugten Ausführungsform arbeitet das Haltemittel nicht auf Anschlag gegen das Widerlager, sondern verformt das Bandagiermaterial, indem es einen Bereich des Bandagiermaterials in das Widerlager hinein drängt, ohne es zwischen dem Klemmglied und dem Widerlager in strengen Sinne einzuklemmen oder zu quetschen. Diese Verformung erzeugt bei Bandagiermaterial wie beispielsweise Stahldraht bereits so viel Reibung, dass eine ausreichende Haltekraft erzeugt wird. Eine weiter bevorzugte Ausführungsform sieht vor, dass das Haltemittel und das Trennmittel von einem gemeinsamen, insbesondere hydraulischen Aktuator angetrieben sind. Dies vereinfacht die Steuerung, insbesondere dann, wenn alle Haltemittel und alle Trennmittel gemeinsam angetrieben werden.In a particularly preferred embodiment, the holding means does not work against the abutment, but deforms the bandaging material by pushing a region of the bandaging material into the abutment without strictly clamping or squeezing it between the clamping member and the abutment. In bandaging material such as steel wire, this deformation creates enough friction to generate sufficient holding force. A further preferred embodiment provides that the holding means and the separating means are driven by a common, in particular hydraulic, actuator. This simplifies control, especially when all holding means and all separating means are driven together.
Wenn außerdem die automatischen Halte- und Trennmittel seitlich an derselben Seite neben dem Ballenkanal angeordnet sind, kann das Bandagiermaterial in räumlicher Nähe zu den Haltemitteln getrennt und dort bereitgehalten werden für die nächste horizontale Umreifung. Die dabei entstehende Menge an zu verwerfendem Bandagiermaterial wird dadurch verringert. Führungsmittel, insbesondere Umlenkrollen, sind an derselben Seite des Ballenkanals vorgesehen, um den jeweiligen Strang des Bandagiermaterial so zu führen, dass er von der Ziehvorrichtung erfasst und quer zu der Pressrichtung entlang der Rückseite des fertigen Ballens quer durch den Presskanal gezogen werden kann.If, in addition, the automatic holding and separating means are arranged laterally on the same side next to the bale channel, the bandaging material can be separated in spatial proximity to the holding means and kept there ready for the next horizontal strapping. The resulting amount of bandaging material to be discarded is thereby reduced. Guide means, in particular deflection rollers, are provided on the same side of the bale channel in order to guide the respective strand of bandaging material so that it is grasped by the pulling device and can be pulled transversely to the pressing direction along the back of the finished bale across the press channel.
In einer besonders vorteilhaften Ausführungsform ist vorgesehen, dass die Führungsmittel im Wesentlichen parallel, also parallel oder in einem spitzen Winkel, zur Pressrichtung verfahrbar sind. In einer anderen Ausführungsform können die Führungsmittel auch um eine etwa vertikale Achse schwenkbar angeordnet sein, so dass die Führungsmittel zwischen einer ersten und einer zweiten Position bewegbar sind. Die erste und die zweite Position weisen dabei in Förderrichtung einen Abstand voneinander auf. Ob die Positionen sich quer zur Förderrichtung in einem Abstand voneinander befinden, ist dabei unerheblich. So können die Führungsmittel die Strangführung beeinflussen, beispielsweise derart, dass der Strang in den Wirkungsbereich der Halte- und Trennmittel gelangt oder daraus herausgeführt wird. Weiter kann alternativ oder zusätzlich vorgesehen sein, dass die automatischen Haltemittel und/oder die automatischen Trennmittel im Wesentlichen parallel, also parallel oder in einem spitzen Winkel, zur Pressrichtung verfahrbar sind. Dann kann der im Haltemittel gehaltene Strang des Bandagiermaterial und/oder die vorgesehene Trennstelle im Bereich der Bandagiereinrichtung beispielsweise von einer Ruhestellung in eine Betriebsstellung und zurück verfahren werden, um zum Beispiel das Bandagiermaterial gezielt der Ziehvorrichtung zuzuführen.In a particularly advantageous embodiment it is provided that the guide means can be moved essentially parallel to the pressing direction, i.e. parallel or at an acute angle. In another embodiment, the guide means can also be arranged to be pivotable about an approximately vertical axis, so that the guide means can be moved between a first and a second position. The first and second positions are at a distance from each other in the conveying direction. It is irrelevant whether the positions are at a distance from one another across the conveying direction. The guide means can influence the strand guidance, for example in such a way that the strand comes into the effective area of the holding and separating means or is guided out of it. Furthermore, it can alternatively or additionally be provided that the automatic holding means and/or the automatic separating means can be moved substantially parallel to the pressing direction, i.e. parallel or at an acute angle. Then the strand of bandaging material held in the holding means and/or the intended separation point in the area of the bandaging device can be moved, for example, from a rest position to an operating position and back, for example in order to specifically feed the bandaging material to the pulling device.
Das Bandagiermaterial liegt zum Beispiel in Form eines Stahldrahtes vor, der für jede Spur in einem linken und einem rechten Strang bezogen auf die Pressrichtung vorgehalten und zu diesem Zweck von je einer Vorratsspule abgezogen wird. Vorzugsweise ist an der den Haltemitteln gegenüberliegenden Seite der Kanalballenpresse eine Drillvorrichtung vorgesehen, insbesondere eine Drillvorrichtung mit zwei angetriebenen Drillgreifern oder Drillhaken, und zwar einem dem Pressstempel näher liegenden, in Pressrichtung stromaufwärtigen Drillhaken und einem dem Ballenausgang näher liegenden, in Pressrichtung stromabwärtigen Drillhaken für jede Spur der horizontalen Bandagiereinrichtung. Dadurch wird sowohl das Bandagiermaterial beider Stränge einer Spur an dem nacheilenden Ende des fertigen Ballens als auch das Bandagiermaterial beider Stränge des voreilenden Endes des nachfolgenden Ballens zuverlässig verbunden, insbesondere verdrillt.The bandaging material is, for example, in the form of a steel wire, which is kept in a left and a right strand for each track in relation to the pressing direction and is drawn off from a supply spool for this purpose. Preferably, a drilling device is provided on the side of the channel baler opposite the holding means, in particular a drilling device with two driven drilling grippers or drilling hooks, namely a drilling hook which is closer to the press ram and upstream in the pressing direction and a drilling hook which is closer to the bale outlet and is downstream in the pressing direction for each track the horizontal bandaging device. As a result, both the bandaging material of both strands of a track at the trailing end of the finished bale and the bandaging material of both strands of the leading end of the subsequent bale are reliably connected, in particular twisted.
Besonders bevorzugt sind die Drillhaken der zweiten, horizontalen Bandagiereinrichtung separat antreibbar, und zwar vorzugsweise alle stromaufwärtigen Drillhaken gemeinsam und/oder synchron, sowie alle stromabwärtigen Drillhaken ebenfalls gemeinsam und/oder synchron. Dabei kann jeweils zwischen einem stromaufwärtigen Drillhaken und einem stromabwärtigen Drillhaken eine zweite Trennvorrichtung angeordnet sein.Particularly preferably, the drill hooks of the second, horizontal bandaging device can be driven separately, preferably all upstream drill hooks together and/or synchronously, and all downstream drill hooks also together and/or synchronously. A second separating device can be arranged between an upstream twisting hook and a downstream twisting hook.
Die Aufgabe wird auch von einem Verfahren mit den Merkmalen des Anspruchs 14 gelöst.The task is also solved by a method with the features of
Weil bei einem Verfahren zum Bandagieren eines Ballens mit Stahldraht in einer Kanalballenpresse, wobei vorgesehen ist, dass die Bandagierung zuschaltbar und abschaltbar ist, ein Abtrennen eines Strangs des Bandagiermaterials mittels einer Trennvorrichtung erfolgt und ein Ende des abgetrennten Strangs bis zu einer weiteren Verwendung in einer Haltevorrichtung gehalten wird, wobei das Halten durch Verformung des Strangs bewirkt wird, kann der Trenn- und Haltevorgang automatisch angesteuert erfolgen und insbesondere das entstehende freie Ende des Strangs an einer geeigneten, definierten Position vorgehalten werden, bis es bei einem später folgenden Bandagiervorgang wieder erfasst und verwendet wird. Es wird so sichergestellt, dass das freie Ende nicht an undefinierten Orten innerhalb der Kanalballenpresse vorliegt.Because in a method for bandaging a bale with steel wire in a channel baling press, it being provided that the bandaging can be switched on and off, a strand of the bandaging material is separated by means of a separating device and one end of the separated strand is in a holding device until further use is held, whereby the holding is effected by deforming the strand, the separating and holding process can be carried out automatically and in particular the resulting free end of the strand can be held in a suitable, defined position until it is captured and used again in a later bandaging process becomes. This ensures that the free end is not in undefined locations within the channel baling press.
Wenn außerdem das Abtrennen und die Verformung durch Ansteuerung desselben Aktuators erfolgt, ist ein synchroner Ablauf sichergestellt, wobei die Steuerung in diesem Fall im Vergleich zu einer separaten Ansteuerung und Synchronisierung von zwei Aktuatoren einfacher gestaltet werden kann.In addition, if the separation and deformation are carried out by controlling the same actuator, a synchronous process is ensured, in which case the control can be made simpler compared to a separate control and synchronization of two actuators.

Die Kanalballenpresse weist einen nicht näher dargestellten Eingabebereich 1 auf, in den zu verpressendes Material lose einzugeben ist. Ein Hydraulikaggregat 2 ist vorgesehen, einen Pressstempel 3 von dem Eingabebereich 1 in einen Ballenkanal 4 zu verfahren und dabei das zu verpressende Material dort zu verdichten. Mehrere Arbeitshübe des Pressstempels 3 erzeugen dabei einen Ballen 5.The channel baling press has an
In der Pressrichtung P gesehen ist in einem stromabwärtigen Bereich des Ballenkanals 4, etwa dort, wo der Arbeitshub des Hydraulikaggregat 2 endet, eine Bandagiereinrichtung mit mehreren Komponenten vorgesehen, die im Wesentlichen aus dem Stand der Technik bekannt sind. Die Bandagiereinrichtung umfasst im Einzelnen eine in dieser Darstellung linke Vorratsspule 10 sowie eine rechte Vorratsspule 11. Die beiden Vorratsspulen 10 und 11 halten in diesem Ausführungsbeispiel ein Bandagiermaterial in Form eines quasi endlosen Stahldrahts für die Umreifung der erzeugten Ballen bereit. Ein linker Strang 12 des Bandagiermaterials verläuft von der Vorratsspule 10 durch ein linkes Führungsmittel 13, das von zwei Umlenkrollen gebildet ist und den Draht zu einer nicht näher dargestellten Drahteinführung des Ballenkanals 4 leitet. Auf der gegenüberliegenden Seite verläuft entsprechend ein rechter Strang 14 von der Vorratsspule 11 zu einem rechten Führungsmittel 15, welches ebenfalls zwei Umlenkrollen aufweist und den Draht zu einer rechten Drahteinführung des Ballenkanals führt.Seen in the pressing direction P, a bandaging device with several components is provided in a downstream area of the
Neben dem Ballenkanal 4 ist im Bereich der Führungsmittel 13 und 15 eine Verbindungsvorrichtung 17 angeordnet, die in diesem Fall aufgrund der Verwendung von Stahldraht als Drillvorrichtung ausgebildet ist. Diese Vorrichtung wird weiter unten noch genauer beschrieben. Hier ist wesentlich, dass die Verbindungsvorrichtung 17 einen ersten Drillhaken 18 und einen zweiten Drillhaken 19 umfasst, die jeweils separat antreibbar sind. Der erste Drillhaken 18 wird von einem ersten Antrieb 20 zur Drehung um eine horizontale Drehachse, die parallel zur Querrichtung Q orientiert ist, angetrieben. Der zweite Drillhaken 19 wird von einem zweiten Antrieb 21 um eine entsprechende parallele Drehachse angetrieben. Beide Antriebe 20, 21 werden von einer nur schematisch dargestellten Steuerung 22 angesteuert.In addition to the
Die Verbindungsvorrichtung 17 umfasst weiter eine Ziehnadel 23, die von einem Antrieb 24 in Abhängigkeit von der Steuerung 20 parallel zur Querrichtung Q verfahrbar ist. Die Ziehnadel 23 ist von der Bauart her an sich aus dem Stand der Technik bekannt.The connecting
Auf der rechten Seite des Ballenkanals 4 ist das Führungsmittel 15 an einem Aktuator 25 angeordnet, der dazu eingerichtet ist, dass Führungsmittel 15 in nicht weit von der Steuerung 20 parallel zur Pressrichtung P zu verfahren. Der Aktuator 25 kann insbesondere hydraulisch angetrieben sein. Zwischen dem Führungsmittel 15 und dem Ballenkanal 4 verläuft der rechte Strang 14 des Bandagiermaterials über ein kombiniertes Halte- und Trennmittel 26, das hier nicht näher dargestellt ist. Das kombinierte Halte-und Trennmittel 26 ist ebenfalls hydraulisch betätigbar und weist ein konkaves festes Widerlager und ein bewegliches, dazu passendes keilförmiges Klemmelement auf, zwischen denen das Bandagiermaterial eingeklemmt und gehalten werden kann. Außerdem ist ein Trennmittel in Form einer Abschervorrichtung vorgesehen.On the right side of the

Die insoweit beschriebene Ausführungsform erlaubt es also, eine Kanalballenpresse mit mehreren Spuren einer Horizontalabbindung so auszustatten, dass die Horizontalabbindung wahlweise ein-und ausgeschaltet werden kann, insbesondere sogar von einem Ballen zum nächsten gewechselt werden kann. Der Wechsel von Ballen mit Horizontalabbindung zu Ballen ohne Horizontalabbindung und umgekehrt kann nach Wahl des Bedienpersonals automatisch von der Steuerung vorgenommen werden. Es kann bei entsprechender Sensorik und Programmierung sogar eine autonome automatische Umschaltung ohne Bedienereingriff erfolgen.The embodiment described so far makes it possible to equip a channel baling press with several tracks of horizontal binding in such a way that the horizontal binding can be switched on and off selectively, in particular even changing from one bale to the next. The change from bales with horizontal tying to bales without horizontal tying and vice versa can be carried out automatically by the control at the operator's discretion. With appropriate sensors and programming, autonomous automatic switching can even take place without operator intervention.
Das Haltemittel 26 umfasst ein konkav ausgebildetes Widerlager 60, das zwei in einem Abstand voneinander montierte Platten 61 und 62 aufweist, und ein ebenfalls plattenförmiges Klemmglied 63.

Die Platten 61 und 62 sind aufrecht montiert und weisen jeweils mit einer Oberseite 65 bzw. 66 in Richtung des Klemmgliedes 63. Die Oberseiten 65 und 66 der Platten 61 und 62 sind abgerundet. Das Klemmglied 63 ist ähnlich plattenförmig gestaltet und weist mit einer Unterseite 67 auf das Widerlager 60, wobei das Klemmglied 63 quer zur Pressrichtung P etwa mittig zwischen den Platten 61 und 62 positioniert ist. Der durch ein Zwischenstück 67 definierte Abstand a der Platten 61 und 62 voneinander ist wesentlich größer als die Dicke des Klemmgliedes 63.The
