Definitions
- the invention relates to a Fliesbandleger with at least two rotating conveyor belts and at least two reversing moved and on Accelerated the reversal points of their travel Dare.
- nonwoven banders are in different Embodiments, for example, from the DE-OS 24 29 106 known. These serve a batt to form a web in several layers superimposed.
- the Flor is made in an upstream card and in a non-woven belt follower downstream Machine, for example a needle machine, further processed. In the latter machine The fleece is pulled together by needles and solidifies, thereby creating a so-called needle felt will be produced.
- the invention solves this problem with the features of claim 1 or 2.
- the tape running speed and the traveling speed of the car are coupled except for the acceleration phases.
- this coupling is canceled and deliberately generates a speed difference, which manifests itself in a change in the deposited edge thickness.
- the pile is elastic and can be compressed and stretched.
- the speed difference according to the invention can by influencing the absolute speeds the conveyor belts and / or the Cart done. In view of the anyway necessary Reversing the car recommends it however, to vary their driving speed and the tape running speed constant hold.
- the structural design can be different his.
- the easiest way is for the car and the Provide conveyor belts separate drives, wherein one or both drives with a freely programmable Control are equipped. It is but equally possible, a common central Provide drive and the end speeds the cart and conveyor belts through infinitely or step-by-step switchable gears or the like to change.
- Fig. 1 and 2 show a nonwoven tape changer (1) in different constructive design, the each from an upstream card (not shown) a pile continuously via a feed conveyor (10) is supplied.
- the pile (8) is in several layers to form a fleece on the storage conveyor (11) filed.
- the nonwoven tape changer (1) a lower laying carriage (5), which in a reversing movement the Flor deposits and an upper carriage (4), which runs in opposite directions reversing back and forth.
- Of the Flor (8) is on his way through the fleece bandender (1) by two endless conveyor belts each (6,7) transported.
- FIG. 1 is a so-called Bandleger (2) shown in which the a conveyor belt (6) in a multi-course Loop over the two carriages (4,5) is guided.
- the second conveyor belt (7) extends into one formed between the two cars (4,5) Loop of the conveyor belt (6).
- the on the car (4,5) arranged pulleys for the conveyor belt (6) be in the reverse-reversing Movement of carriages (4,5) moved while the other pulleys fixed in place are.
- the continuously fed pile (8) passes over the carriage (4) in the transport gap between the two in the same direction in this area Moving conveyor belts (6,7) and moves to Going through a loop on the laying carriage (5), from which he over the fleece (9) back and forth is moved and stored.
- the disposal conveyor (11) moves the web formed from the piles (9) slowly forward.
- the two cars (4,5) are connected by a common drive and move at different speeds in the opposite direction.
- the carriage (4) runs at half the speed of the car (5) and puts it halfway from the car (5) back.
- the drive (12) is designed as a servo drive and connected to a freely programmable controller (13).
- the speed of the car (4,5) can thus be changed arbitrarily on their track, with the acceleration phases in the reversal points of the driving movement are arbitrarily influenced.
- the two conveyor belts (6,7) have in the illustrated embodiment separate drives (14), preferably also servo-drives, however, acted upon by a common control (15) and are set to the same conveying speed.
- the tape drive (14, 15) runs constantly, giving to the conveyor belt (6) the tape running speed (V b ) equal to the conveying speed of the feed conveyor (10) can.
- V b the tape running speed
- the carriages (4, 5) can have separate drives. It is also possible to keep the carriage speed (V w ) constant and to vary the belt running speed (V b ), whereby the feed speed of the pile (8) is correspondingly varied by additional measures, such as upstream storage.
- Fig. 2 shows a so-called.
- Wagenleger (3) whose Both cars (4,5) each have their own endless revolving Have conveyor belt (6,7).
- the car drives (12) in common or be separated and are with a freely programmable Control (13) connected.
- the Constant drives do not need this, but they can also be equipped with it.
- the servo drives have a highly dynamic engine behavior, so that the drives be placed exactly in the per thousand range can be used to increase the thickness in the percentage range control.
- the servo drives can be different be designed and consist for example of Three - phase motors with frequency converters and Tacho control.
- the records are advantageously only the speed profile, but not the actual driven speeds.
- the speeds can change during operation and get online via the microprocessor about the speed profiles and the current ones Florschreib für calculated.
- FIG. 3 is a diagram showing five different relative relationships between the carriage speed (V w ) and the tape running speed (V b ).
- FIG. 4 shows the resulting thicknesses of the uppermost, just deposited pile. The affiliation of the possible variations is shown in Fig. 3 and 4 by the same line types.
- Fig. 3 shows the speed over time or the way. Both diagrams assume that the tape running speed is constant. In both diagrams, the solid line represents the reference line. In Fig. 3 it illustrates the tape running speed (V b ) and at the same time the one possibility of variation in the tape running speed (V b ) and Wagenschwangkeit (V w ) are equal. For the sake of simplicity, in the diagrams, the acceleration phases for the car speed at the turning points are omitted. These may look different depending on the type of control and, for example, linear or according to DE - OS 24 29 106 run in a trigonometric function.
- the upper horizontal and dash-dotted lines Line denotes the second possibility of variation, in the car speed is greater than the tape speed. This leads to the diagram of Fig. 4 to a even lower board thickness.
- the laying carriage (5) moves faster compared to the fleece (9) as the pile (8) from the belts (6,7) downwards becomes.
- the discarded pile (9) becomes thereby streamlined and diluted accordingly.
- the third possibility is shown in dashed lines in FIG. 3 and consists of a carriage speed (V w ) which is constant over the travel path (apart from the acceleration phase) and which is lower than the belt speed (V b ).
- V w carriage speed
- V b belt speed
- the fourth variation consists in a speed difference between (V w ) and (V b ) which differs spatially or temporally over the travel path.
- the difference can be constant or, as in the embodiment shown, vary in height or in height.
- the carriage speed can be changed in stages or continuously depending on the type of control used and the type of thickness change desired.
- the speed curves shown in FIG. 3 can be reversed forwards and backwards on the same line.
- the pile tray in the forward and return of the laying carriage (5) is influenced in the same way.
- a special fifth option is shown in dotted lines in FIGS. 3 and 4. It relates to the compensation of the edge accumulations of the fleece (9) due to the braking and acceleration operations of the laying carriage (5) in the reversal points.
- (V w ) is here lower than the constant (V b ) with the consequence of the partial Florverdickitch.
- the carriage speed (V w ) is increased beyond the tape running speed (V b ) beyond the reversing point, kept constant a bit and then returned to (V b ).
- Fig. 4 shows at the left edge, as a result, the edge accumulation merges into a FlorverBanknung and then back into a normal Flordicke.
- the deposited pile (9) in this edge region has sufficient time to reduce the accumulation of margins by the artificially generated inner pile tension, which is additionally supported by natural shrinking processes.
- the laying carriage (5) is braked to 0 at the end of its travel, which leads to the edge accumulation shown on the right-hand edge of FIG. 4.
- the laying carriage (5) in variation to the laying carriage (5) but also accelerated shortly before reaching the reversal point for FlorverPhymbi and then be slowed down.
- the laying carriage (5) On the way back (not shown), the laying carriage (5) in turn accelerates in the same way as on the way over the tape speed (V b ) addition. In this way, both edge accumulations are compensated.

Description
Normalerweise sind die Bandlaufgeschwindigkeit und die Fahrgeschwindigkeit der Wagen abgesehen von den Beschleunigungsphasen gekoppelt. Mit der Erfindung wird diese Koppelung aufgehoben und bewußt eine Geschwindigkeitsdifferenz erzeugt, die sich in einer Änderung der abgelegten Flordicke äußert. Läuft der Legewagen langsamer als das Förderband wird der abgelegte Flor dicker, während umgekehrt bei einem schnelleren Legewagen die Flordicke geringer wird. Der Flor ist elastisch und läßt sich stauchen und strecken.
- Fig. 1
- eine schematische Darstellung eines Vliesbandlegers in der Ausführung als Bandleger mit ineinandergeführten Förderbändern,
- Fig. 2
- einen Vliesbandleger in einer Ausführung als Wagenleger mit getrennten Förderbändern für jeden Wagen,
- Fig. 3
- ein Diagramm der Geschwindigkeits-Verhältnisse über der Zeit und
- Fig. 4
- ein Diagramm über die Änderung der Flordicke über der Zeit in Relation zu Fig. 3.
Variationen des gezeigten Beispieles sind in verschiedener Weise möglich. Zum einen können die Wagen (4,5) getrennte Antriebe aufweisen. Es kann auch die Wagengeschwindigkeit (Vw) konstant gehalten und die Bandlaufgeschwindigkeit (Vb) varriiert werden, wobei durch zusätzliche Maßnahmen, wie vorgeschaltete Speicher etc. auch die Zuführgeschwindigkeit des Flors (8) entsprechend variiert wird.
Der Einfachheit halber sind in den Diagrammen die Beschleunigungsphasen für die Wagengeschwindigkeit an den Umkehrpunkten weggelassen. Diese können je nach Steuerungstyp unterschiedlich aussehen und beispielsweise linear oder entsprechend der DE - OS 24 29 106 in einer trigonometrischen Funktion verlaufen.
Mit der gezeigten Flordickenänderung kann beispielsweise Ungleichmäßigkeiten bei einer nachgeschalteten Nadelmaschine vorgebeugt werden, wenn diese am rechten Vliesrand nur sehr wenig und dann in den mittleren Bereichen wieder stärker verdichtet. Die Schwankungen der Nadelmaschine würden in so weit der Kurve (Vw) in Fig. 3 entsprechen.
