Definitions
- the invention relates to methods for measuring the weight of an endless stream of web-shaped fiber material and to an apparatus for carrying out the method according to the preamble of the method or device claim.
- a device for transporting a fiber layer to a carding machine is known.
- the transport route begins at a Rütischachtspeiser, which deposits fibers on a first conveyor belt.
- the fiber layer passes to the circulating conveyor belt of a belt scale via a further driven conveyor belt and from there to the insertion of a carding machine.
- sensors In the belt scale via there mounted measuring devices, sensors, the determination of the weight of the located on the band of the belt scale fiber layer signals.
- the signals are fed to a controller, which processes these in conjunction with speed signals of the carding machine, such that the carding forms a uniform, uniform nonwoven fabric.
- the fiber layer to be analyzed by the belt weigher with respect to its weight is transferred from a conveyor belt in the previous transport conveyor belt scale, and then from the belt weigher to another, downstream conveyor belt, which serves to feed a card.
- the guide rollers of the corresponding conveyor belts are parallel to each other.
- the fiber layer of the one on the following de transport conveyor unsupported.
- distortions occur in the transfer areas which, due to the resulting stresses, lead to a falsification of the measurement result of the belt scale.
- a device for feeding fibers to a textile machine is known from DE 10 2008 022 817 A1, in which fibers are deposited via a shaft on a take-off device designed as a circulating transport belt. Below the shaft, the weight of the fibers deposited thereon is measured with a first measuring device and controlled according to the transport speed of the conveyor belt. Thus, for example, a downstream opening unit, a constant fiber mass per unit time can be supplied.
- This known device has, in addition to the first measuring device in the conveying direction of the fibers behind the shaft, a second measuring device. Due to the nature of the fibers caused by the behavior of the fibers within the shaft or in the filing of the fibers on the conveyor belt can not be determined by the first measuring device, the correct weight. Due to the second measuring device in a region in which the fibers have left the shaft, the actual belt located on the belt is measured quantity. This primary and secondary measurement results in a differentiated control of the fiber flow.
- the present invention is therefore based on a method for measuring the weight of an endless stream of web-shaped fiber material, which is conveyed on a revolving conveyor belt, wherein formed by means of an associated measuring system corresponding to the weight of the fiber material located on the conveyor belt signal and this particular for controlling a the fiber material processing machine is used.

- the machine processing the fiber material is preferably a carding machine and / or a stacker.
- the area weight value of the fleece produced by the carding machine and / or the crosslapper is used in the region of the circulating conveyor belt.
- the basis weight, the basis weight is determined by a radiometric measuring principle. Known measuring principles for determining the basis weight use isotope radiation sources such as promethium, krypton or strontium.
- the radiation passing through the material or radiated back from the material is detected, wherein the basis weight of the nonwoven can be determined from the intensity of the respective radiation.
- optical measuring methods can also be used.
- the basis weight is also the width of the web of the fiber material, the fleece and the speed of the web determined. From the basis weight, the width of the fiber or nonwoven web and the speed of the mass flow rate can be calculated, ie the mass of fiber or nonwoven material per unit time.
- the device for carrying out the method consists of an endlessly circulating conveyor belt, on which fiber material is transported, wherein the conveyor belt forms a belt scale with an associated measuring system, and an evaluation device which is in signal communication with the measuring system, for determining the weight of fiber material.
- the evaluation device additionally receives a signal from a measuring device for determining the basis weight of the basis weight of the fiber material, the measuring device being arranged downstream of the conveyor belt in the transport direction.
- the following measures are planned:
- the measuring device for determining the basis weight is arranged starting from a fiber material processing machine, which is arranged downstream of the conveyor belt.
- the evaluation is connected to the control of the fiber material processing machine and thus is part of a control system through which the control and in particular the control of the speed of the fiber material processing machine takes place.
- the machine processing the fiber material is a card and / or a stacker.
- the measuring device for determining the basis weight is a transversely to the conveying direction of the fiber material movably suspended measuring head.
- the measuring device for determining the basis weight is a radiometric measuring device.
- the web-shaped fiber material is a fiber layer, which is deposited by a feeder (Rüttelschachtspeiser, Krempelspeiser) on a first conveyor belt. This fiber layer is then transferred to a second circulating conveyor belt, which forms a belt scale with an associated weight measuring system. Subsequently, a further transfer of the fiber layer to the collection of a card.
- the pile formed by the carding is laid by a cross-lapper to a fleece of intended thickness.
- the output of the cross-stacker is a surface mass, the basis weight of the nonwoven determining measuring device arranged, which operates on a radiometric principle of action.
- the measuring system is suspended on a transverse to the direction of movement of the nonwoven web traverse and performs during the measurement periodic reciprocating movements across the width of the nonwoven web.
- the homogeneity of the nonwoven web as well as density fluctuations can be recognized.
- the width of the nonwoven web can be determined.
- the signals of the area measuring system and the speed signal output of the cross stacker are used to correct the results of the weight measuring system of the belt scale at the beginning of the carding.
- the time average of the mass flow (mass per unit time) output of the Wienlegers equal to the time average of the mass flow at the beginning of the carding (mass flow over belt scale).
- the ratio of the mentioned mass flows is equal to one.
- the mass flow output of the crosslapper results from the product basis weight, product width and production speed.
- the web width is hereby continuously determined by the area measuring system itself, by detecting the signal jumps which occur when the edges of the nonwoven web are passed over and with the . Position signals of the measuring head are processed.
- the production speed is known and is present as a corresponding signal of the control of the card / the crosslapper or is detected with a separate speed sensor.
- a correction factor can be determined by the method according to the invention, which indicates how much the weight value of the fibrous layer in the area of the belt weigher is actually higher or lower than the measured value determined merely by means of a belt weigher.
- Fig. 1 shows a schematic diagram of the solution according to the invention.
- 2 shows a top view of the conveyor line according to FIG. 1.
