Definitions

  • the invention relates to a device and a method for packaging and pressing fiber flakes from short-cut fibers or other fibers with high sliding properties in bale form.
  • the rigid coupling of the pre-press and main press system has been broken, in that the press boxes used can no longer be assigned to a specific press, but are freely movable and can be temporarily stored in order to be fed to a pre-press or the main press in any order.
  • the press boxes used can no longer be assigned to a specific press, but are freely movable and can be temporarily stored in order to be fed to a pre-press or the main press in any order.
  • press boxes which can be of any type and can be transported in any way.
  • EP-B1-0 014 923 in which the final pressing can be carried out in the transportable press containers. According to this patent, the final packaging and reinforcement of the bales produced takes place in the final press. If a higher utilization of this press is required, EP-B1-00 29 977 teaches that the packaging operations can also take place outside the actual main press.
  • a prerequisite for all of these packaging processes is that the staple fibers to be packaged have a certain degree of cohesion, thus ensuring, for example, the addition or storage of the flake in the pre-press, but also the stability of the bale before the final packaging and reinforcement.
  • These prerequisites no longer exist for a number of so-called short-cut fibers, ie fibers with a maximum cut length of approximately 20 mm, preferably 4 to 12 mm.
  • Such materials which are used, for example, as reinforcing fibers in inorganic matrices, moreover usually have little or no crimp. But even with crimped material, undesirable sliding operations can occur, such as. B.
  • box bags such as has previously only been used for the packaging of thread cables, is suitable for ensuring the stability of the pre-pressed or end-pressed material, provided that care is taken to ensure that the filling with fiber flake produces as few inhomogeneities as possible and has mass differences.
  • Figure 1 shows a schematic representation of a suitable device for filling and pressing such fiber flake.
  • Figures 2a and 2b show a section along the plane II-II 'of the device according to Figure 1 again.
  • Figure 2a contains a swivel trunk in the filling shaft, while Figure 2b has a movable paddle at this point.
  • Figure 3 shows a further embodiment of the device in which the press box is moved back and forth.
  • FIG. 4 shows a further embodiment of the device in which the clearing device is moved back and forth.
  • Figure 5 shows a possible arrangement of depositing devices and associated presses and a final press in a schematic representation.
  • Figure 6 shows a product produced in the form of a bale.
  • the mode of operation of the device for packaging and pressing fiber flake and the method to be followed are first to be described generally in connection with FIGS. 1 and 2a and 2b.
  • the fiber flake to be packaged reaches the device via a delivery tube (1) and falls through the filling shaft (2) into the opening (30) of the clearing device.
  • a distribution of the fiber flake is necessary here.
  • the filling shaft at least at its lower end (3), already has a width that largely corresponds to the width of the press container (11) into which the material is to be packaged and pressed.
  • the use of a pivotable distribution device (6) is necessary.
  • This swiveling distribution device can consist, for example, of a swiveling trunk (17) which is moved back and forth in the filling shaft (2) with the aid of a movement device (19).
  • the same distribution task can also be solved by a swivel-mounted paddle (18), which is again connected to a drive device (19). With the help of such devices, it is possible to fill the space above the discharge opening (3) of the filling shaft (2) uniformly over the entire width (4) with fiber flake. The flake is then taken over by a clearing device (7).
  • This clearing device can consist, for example, of an endless conveyor belt with attached knobs or hooks or an oscillating conveyor of corresponding width (4).
  • this broaching device is capable of further transporting the pile of fiber flake produced by the swiveling distribution device (6) without there being any noticeable change in the flake density, measured over the width of the broaching device.
  • the clearing device (7) is shown as an arrangement of several screw conveyors (20), in which the pitch of the screw spirals (21) may increase in the direction of the discharge opening (22) via a drive (29) can be moved.
  • the use of screw conveyors is preferred for stack lengths of less than 20 mm, while nubbed belts, in particular over 20 mm of cut length, can bring advantages in the case of crimped fibers.
  • Vibratory or vibratory conveyors are characterized by particularly gentle transport, avoiding the formation of braids or the like.
  • this clearing device (7) or the several screw conveyors (20) arranged in parallel next to one another it is possible to distribute the fiber flake evenly over the length (10) of the opening (5) of the press container (11), provided that either the discharge opening ( 22) the screw conveyor (20) or the clearing device (7) executes a relative movement to the opening of the press container (11) in such a way that the stroke distributes fiber flake evenly over the entire length (10) of the opening (5) of the press container (11) or the resulting flake is first accumulated in an equalization chamber (8) in order to then accumulate in the press container (11).
  • a possible embodiment for such an equalization of the fiber flock density also in the longitudinal direction is the use of a compensating device, which consists of a compensating space (8) in which the flake delivered by the clearing device (7) is piled up.
  • This compensation space (8) has a bottom surface which is formed by the slide (23).
  • This slide which is optionally made of several parts, can completely separate the compensation space (8) from the interior of the press container (11) and, in the open state, completely connect these two spaces to one another without there being an impediment to the transport of fiber flake into the press container .
  • the two longitudinal walls (24) of the compensation space (8) are preferably aligned with the inner walls of the press container (11) located below.
  • the compensation chamber (8) is closed at the top by the press ram (12).
  • one side wall is the discharge opening (22) of the clearing device (7); a press ram is arranged opposite it, which can be advanced over the entire length (10) to the discharge opening (22) and against which the fiber flock is then conveyed.
  • the counter pressure ram (25) can provide a predetermined resistance to its movement against the conveying direction of the discharge device (7), which can be accomplished, for example, by a piston-cylinder unit (40) controlled by compressed air. Due to the required force, a combination of vibratory conveyor and counter pressure stamp (25) is not possible without special measures.
  • this longitudinal equalization device (9) thus consists in distributing the resulting fiber flake in width by the device (6) and by filling the compensation space over the length (10).
  • the clearing device (7) is stopped, the counter pressure stamp (25) is held in its end position and the slide (23) is opened completely.
  • the material accumulated in the compensation chamber (8) is then brought into the interior of the press container (11) by lowering the press ram (12). After lifting the ram (12) into its upper rest position, closing the slide (23) and moving the counter-pressure ram (25) up to the discharge opening (22) of the clearing device (7), the clearing device (7) can go into operation again and close again a gradual filling of the compensation chamber (8) against the resistance of the counter pressure ram (25).
  • FIGs 1 and 2a and 2b also show the basic structure of the press container.
  • This press container (11) should have a rectangular cross section and preferably have no internal internals, such as retaining devices or lacing grooves or the like. It is a rectangular hollow body with the inner width (4) and the length (10), which is closed at its bottom by a releasable base plate (16).
  • this base plate can be held in a drawer-like manner in the lower part of the press container (11); further solutions for such a base plate are already known in the prior art.
  • packaging material (15) preferably with an already prefabricated box bag which is held at the upper edge of the press container by clamping devices (14).
  • the packaging material for the special fiber flake with increased sliding properties can either be a box sack that is dimensioned so generously that after filling with the fiber material and compression by the press ram (12) before the last, final pressing, for example with the press ram (12) can be closed overlapping.
  • another type of packaging (15) can also be used.
  • a box sack is used, which has approximately only the size of the side walls and the base plate of the press container (11) and, for example, subsequently receives an overlapping cover film for covering the end face before the final pressing.
  • the press container (11) should be designed so that it can absorb the pressure acting on it in any case.
  • reinforcements (41) are indicated on the outside of the press container.
  • a light design of the container (11) is also possible if the walls of the press container (11) can be supported flat during the pressing or the press box (11) can be removed from the material to be pressed at least before the final pressing.
  • the press container (11) are preferably freely movable, ie they are not connected to the storage or pressing device via guides or rods. Rather, you can use suitable means of transport, such as floor conveyors or roller conveyors or the like, can be transported as desired. In particular, transport to a separate final press (34) is possible, which works independently of the device for packaging and pressing fiber flake described here. However, in a simplified embodiment, the device according to FIG. 1 is already suitable for a final pressing. In this case, the press box (11) should be removable from the pressed material after the detachable base plate (16) has been released, so that unimpeded packaging of the compressed fiber material in bale form is possible.
  • the press containers (11) preferably also have no otherwise customary retaining flaps. Due to the special properties of the fiber material to be packaged here with high sliding properties and mostly little crimping, the tendency of the pre-pressed material to swell out of the press container after the press ram has been returned is slight.
  • the retaining flaps as they are known from the prior art for the packaging of normal fiber flake, mostly have no effect here due to the high lubricity of the fibers, their retaining effect is usually so limited that it can be dispensed with.
  • the actual packaging and pressing of the fibrous material is carried out according to the method according to the prior art in such a way that a certain amount of fiber material is introduced into the press container and then the press ram (12) is lowered in order to pre-compress this material; afterwards the ram is raised and after further filling it is used again. It is thus possible to pre-compress the material sufficiently, especially if it was possible due to the devices used, one To achieve as uniform a filling of the press container as possible with the fiber flake.
  • FIG. 3 Another embodiment has been shown schematically in FIG. 3.
  • the distribution of the fiber flake over the width of the press container (11) is carried out in the same way as described above, but the distribution in the longitudinal direction (10) of the press container is different here.
  • a relative movement of the press box (11) or its opening (5) to the discharge opening (22) of the clearing device (7), which in turn was shown in FIG. 3 as an aggregation of several screw conveyors, is used for the uniform distribution in the longitudinal direction.
  • the relative movement of the clearing device or discharge opening of the clearing device and the press container (11) takes place by using a traversing device (26), which leads to a back and forth movement of the press box (11).
  • the filling shaft (2) there is at least one foreign body sensor (31) or the like, which is coupled to the drive of the clearing device (7) in such a way that when this detector responds, the clearing device (7) in its conveying direction for a certain short time is reversed and now the fiber material can be automatically excreted together with the foreign body via the nozzle (32).
  • Foreign bodies of this type are, for example, knife fragments which can be recognized very well by corresponding metal detectors.
  • FIG. 4 shows another embodiment of the device according to the invention.
  • the distribution over the longitudinal direction (10) of the press box (11) takes place by a traversing movement of the entire clearing device (7), while the press container (11) is fixed in the filling and pressing position.
  • Further press containers (11) in addition to the actual press container in the press position are intended to indicate the introduction and removal of such press containers.
  • the left press container should still be empty, only equipped with a box sack, while the right container (11) already contains pressed goods that are to be fed to a final press.
  • Roller or roller conveyors (37, 38) are indicated here as transport devices.
  • the clearing device moves back and forth in this embodiment.
  • a traversing device is used, which moves the clearing device (7) including drive (29) back and forth.
  • the stroke of this traversing device should be oriented in such a way that the opening of the press container (11) is completely released in a left end position, so that the press ram (12) can be lowered and, on the other hand, the stroke is sufficient to achieve a uniform To allow scattering of the fiber flake over the entire length of the press container.
  • the clearing device (7) can consist of a correspondingly wide vibrating or vibrating conveyor.
  • the discharge opening (3) of the filling shaft (2) which is connected to the inlet opening (30) of the clearing device (7), is also accommodated in this traversing device. It is necessary, for example, to connect the filling shaft (2) or the delivery tube (1) for fiber flake to at least one elastic connecting member (36) and possibly also (42). These elastic links are made of, for example made of elastic plastic or rubber and have approximately the shape of the filling shaft.
  • the two end positions in the traversing of the clearing device (7) are again indicated in FIG. 4. The end position is indicated in solid lines, in which the use of the press ram (12) is possible without damaging the clearing device. In the dash-dotted version, the other end position is indicated, which is necessary for the discharge of the fiber flake to the other side of the press container.
  • foreign body sensors (31) are provided and a reversing device of the drive (29) so that foreign bodies can be ejected via the connection piece (32).
  • FIG. 4 shows a base (43) which also has transport devices for the press container (11) but also corresponding positioning devices (13).
  • force transducers can be attached here, which are attached, for example, to pneumatic actuators (not shown) and with the help of which a continuous control of the degree of filling, i.e. that is, the amount of fiber flake filled in can be carried out.
  • these force transducers (44) are pivoted out or shut down again before actuation of the press ram (12) in order to prevent damage during the actual pressing process, if possible. If several load cells are used, the uniformity of the distribution of the fiber flake may even be tracked and the effectiveness of the distribution devices (6) and / or (9) may be influenced.
  • the mode of operation of this device is similar to that already described for the device according to FIG. 1.
  • the fiber flake falls through the filling shaft (2) and the elastic members (36) and optionally (42) into the broaching device, after being evenly distributed over the width of the by a pivotable distribution device (6)
  • Fill shaft has been distributed.
  • the lower discharge opening of the filling shaft and the clearing device already have a working width which corresponds to the width (4) of the press container (11).
  • the clearing device moves back and forth between two limit points. One limit position allows the press ram (12) to be lowered into the press container (11) without risk, the other end position satisfies the requirement for an even distribution of the fiber flake over the full length of the press container (11).
  • the press containers (11) are lined in the form of a box bag before being filled with packaging material. These box bags are held by appropriate clamping devices (14). By pressing from time to time with the aid of the press ram (12), the fiber material is compressed. After the packaging has been completed or closed, the fibrous material can be finally pressed in the press container (11). It is then possible, using suitable devices, to remove the press container (11) from the pressed material after removal of the detachable base plate (16) and the fiber flake in the strongly pressed state, for example by introducing reinforcements made of steel strip or wires (33) in bale form (35 ) to fix (Fig. 6). It is also possible to remove the press container (11) before the final pressing.
  • Such final pressing and packaging of the material does not have to be carried out with the help of the press ram (12) of the device, but can also be carried out in a possibly separate press (34) with or without a feeding container (11).
  • FIG. 5 A schematic representation of a possible arrangement is shown in FIG. 5.
  • the press boxes (11) pass from the pre-pressing devices via roller conveyors (37) to a central press (34), in which the final pressing and packaging is carried out.
  • the empty press containers are sent back to the storage and pre-pressing devices via roller conveyors (38).
  • Such a system can be part of a larger crimping system using various pre-presses or cable trays. These options have been indicated by the additional roller tracks (39).
