Definitions
- the invention relates to a method and a device for Mixing fiber components by means of weighing box feed, the equipped with a weighing container and a Vorhellraum is, wherein the weighing container from the upstream Vorhellraum separated by a controllable flap, and after weigh the material from the weighing container on a Mixed tape is dropped.
- the weighing of the fibers according to this known discontinuous Procedure is usually done so that the weighing container with two different material feed speeds is fed, the feed rate of the needle belt speed is determined.
- this high needle belt speed only inexact the desired To reach cradle weight. That's why this fast filling is only carried out to a certain degree of filling.
- the Needle belt switched to low speed, and it follows with this low speed the fine dosage, until the desired final weight is reached.
- the needle band is stopped. Then the exact weight is determined by the balance.
- the Balance is at a standstill, i. that they are not through the Filling caused vibrations more. This process may take up to 2 or 3 seconds.
- the Weighing container emptied onto a so-called mixed belt and tared, i. the weighing device is exactly at zero point set. This is the weighing device for the next weighing prepared, and the needle band is again turned on, first at high speed the Coarse filling for the next weighing process.
- Fiber blenders are usually equipped with multiple weighing bins and operated with different raw materials. The slowest Weighing determines the throughput of the entire production plant. In the described weighing process the Achieving the desired accuracy and throughput is what it's all about necessary that the facility of operators with good Process knowledge and experience is discontinued. The Setting values must be determined empirically for each fiber type be, which is expensive.
- a device for dosing Contents known for filling packages filling the Weighing container takes place via two stages with a coarse dosage and a fine dosage.
- the Filled product is directed via a first supply line into an antechamber, provided with a shut-off device to the weighing container is, wherein a volumetric dimension of the contents in the Antechamber is provided.
- Upon reaching the given Volume is completed filling the antechamber and its Content emptied into the weighing container.
- After closing the Absperroganges between pre-chamber and weighing container takes place the fine dosage over a second conveyor line.
- FIG. 1 shows a weighing feeder schematically in its construction.
- the bales 1 ', 1' ', 1' '' are above the feed table 2 and the conveyor belt 3 is supplied to the needle belt 4, which from the fed bales of patties and raises up against the stripper roller 5 promotes.
- the rear roller 5 is in her Distance to the needle belt 4 adjustable and rotates in the Antisense to the conveying direction of the needle tape 4. Too large Amounts of fiber that rise with the needle tape 4, by this distance of the stripper roller 5 is not allowed to pass, but held back by this.
- Conveyor belt 3 of the feed table 2 and the needle belt 4 drivingly connected with each other.
- a infinitely variable drive 41 provided so that the needle belt each predetermined by a controller 41 Conveying speed can run. Close to the needle band 4 the rotating at high speed knockdown 6 on, which strikes the fiber material from the needle tape 4 and it opens. The detached by the knock-off roller 6 Fibers or fiber flakes are conveyed into a prefilling space 8, which closed by flaps 9 and against the Weighing container 10 can be shut off. A fan 7 ensures dust extraction. Under the weighing container 10 is a mixing belt 12 along which the in the weighing container 10 weighed fibers are dropped. At the end of Mischbandes 12, a pressure roller 11 is arranged to the Fiber material to a uniform cotton for feeding in to compact a mixing opener 13.
- FIG. 7 shows a weighing feeder with an enlarged pre-filling space 80. Parts of this weighing feeder with the same function are Also referred to as in Figure 1, so that the description of the weighing feeder according to FIG. 1 also applies to FIG. 7.
- a large Vor colllraum 80 is arranged, up to about 80% of the capacity of the weighing container 10 Has.
- This enlarged Vor buoy serves to during the the settling time of the balance and the discarding of the contents the weighing container 10 supplied on the conveyor belt 12 material take, so that the needle belt 4 without stopping Can promote fiber material.
- the level Vorhellraumes are on both sides of measuring devices 13th arranged. Preferably, these measuring devices consist of Light barriers.
- FIG. 2 shows a system with three weighing box feeders I, II and III, each having a component on the mixing belt 12th discard.
- the dropping out of the weighing containers 10 takes place in each case so that the components to be mixed are stacked on top of one another and at the same time to move into the mixer opener 13 arrive. That First, the weighing feeder III throws its component content on the mixing belt 12, which this Location transported to Wiegespeiser II. There will be from the Weighing container 10 the next component on the location of Wiegespeisers III launched and both continue to Wiegespeiser I transported that then the third component to the two Apply layers. All three layers run at the end of the conveyor belt 12 under a pressure roller 11 and are the Mischöffner 13 fed, the layer packages continuously mixed and through the pipe 14 to a mixing chamber emits.
- the loading of the weighing container 10 takes place in a known Device in such a way that in a first phase of Material transport runs fast without weight control, i. the butterfly valves 9 are closed, and the material accumulates in the Vorphilllraum 8. During this time closes the bottom flap of the weighing container 10 after discarding the last weighing, and there is a balance when the Bottom flap is closed. In a second phase, the Material transport still fast and without weight control, but the butterfly valve 9 opens and throws the accumulated Material in the weighing container 10, the bottom flap closed is.
- the pre-filling serves to increase the production capacity by Reduction of downtime of material transport, since with closed shut-off valve 9 in the first two phases Already the material transport can use again. Indeed is the prefill function according to the known method not applicable if the material transport speed subject to strong fluctuations.
- the material is supplied with different Speeds, but it is constantly in operation, so that no downtime occurs.
- the invention is unnecessary to adjust the individual Parameters, as the individual speeds for material transport and filling including time intervals optimize it automatically within the weighing cycle and thereby adjust to the different materials at the same time.
- the procedure according to the invention is as follows:
- the weighing cycle is essentially divided into three phases, (Fig. 6) in priming (zone A), main filling (zone B) and fine filling (zone C). In addition there is the downtime (Zone D). With a corresponding size of Vor colllraumes 8 and 80 can be dispensed with the main filling completely, so that the Weigh cycle only in priming (zone A + B + C) and Fine filling (zone D) divided.
- the pre-filling takes place at closed flaps 9 in the Vor Reichllraum 8 and 80th During This so-called prefilling takes place the settling time of the balance and the final weight measurement as well as the opening and dropping of the Final weight on the mixing belt 12 including the possibly necessary taring of the balance.
- Figure 3 shows the unitary curve for a weighing cycle without downtime of the material supply.
- the flow rate at the beginning of the cycle is about 100 %. This flow rate is about 60% of the time of weighing cycle maintained. Then the flow rate is lowered to about 20% and for the remaining 20 to 25% of the Weighing cycle time with decrease of the flow rate the fine dosage made to final weight.
- the area under the unit curve represents the total flow rate during the weighing cycle reached and as a final weight on the mixing belt 12th should be dropped. By integrating this unity curve results in the target weight curve ( Figure 5).
- the unit curve is used for each mixed component I, II and III, where 100% is the flow rate required during the weighing cycle time, the target weight of the corresponding Reach component.
- component I has the highest setpoint speed, here in the example with 60 m per minute, the Component II at 30 m per minute and component III with about 10 m per minute. This corresponds approximately to the mixing ratio of the components of 60: 30: 10.
- FIG. 6 shows in a comparison what enormous advantages the removal of downtime in favor of a has continuous material supply.
- the strongly drawn unit curve sets the weighing cycle with the usual downtime Zone A indicates the usual prefill time, zone B is the main filling, while zone C is the fine filling and finally the zone D the downtime of the supply indicates.
- the percentages give as an example a usual Sequence of the weighing cycle. It is irrelevant whether the weighing cycle lasts 12 seconds or 16 seconds. in the In this case, the example was a weighing cycle of Taken 14.5 seconds.
- the pre-filling takes place with a material conveying speed, which is tuned so that the existing Vor colllraum 8 or 80 well in the given or available time used and optimally fed. Is the size of the Vor colllraumes 80 (Fig. 7) about 60 to 80% of the weighing container 10, so the essential filling takes place in this Vor colllzeit. After opening the flaps 9 this Vor colllmenge arrives the weighing container 10, and it is only a fine filling with low conveying speed required to to achieve the desired final weight exactly.
- the material promotion starts with the through the target weight curve (Fig. 5) conditional conveying speed (Fig. 4).
- a setpoint / actual value comparison with the specified target weight curve it is determined which amount is still up to Final weight is to fill. If the difference is very large, so the material conveying speed can only be increased again 100% increase and only for the last 10 or 20% on the Fine promotion be down regulated.
- the goal is, however, with one the conveying speed is as uniform as possible so that the conveying speed at the following Cycle for this Vor colllzeit already adjusted in total.
- the correct speed of the material feed during this prefilling period because this can from the target speed determined from the target weight curve (Fig. 4) differ by the specificity of the material. Although this can basically be done by hand and by Input of empirical values. It is also possible that the weighing device optimizes itself here. This happens in the following way:
- a Method is, for example, that by opening the Butterfly valves 9, the previously filled Vor colllmenge in the Weighing container 10 is dropped, so that this intermediate weight can determine which is given to the calculator this compares with the target weight. Is this actual value below the set point, this means that the 50% fill speed is too low and according to the difference between actual value and setpoint must be increased.
- the calculator the right conveying speed before, so that an optimal utilization of the Vor colllraumes 8 and 80 takes place. If the pre-fill quantity is too high, the speed is reduced accordingly. In order to The usual adjustment measures are unnecessary. For refinement This process can also be repeated.
- Vor Reichllraum 8 Another way of optimizing the prefill speed is the Vor Reichllraum 8 with a measuring device for to equip the degree of filling (measuring probe, light barrier, etc.).
- the Vor Reichllraum 8 is filled until the encoder responds and indicates the filling of the room, causing the flaps 9 to open.
- the required time is determined and calculates the optimum filling speed in the calculator and adjusted by raising the default or else is lowered.
- the pre-filling quantity then brought to the final weight and as a first weighing be used.
- the following weighing cycles are after the optimization the optimal conveying speed.
- the controller switches to the through the target weight curve specified filling speed.
- a Regulator which expediently on the delivery speed of the needle belt 4
- the speed is along controlled this curve, so that a corresponding decrease the filling speed takes place to the fine dosage when reaching make the final weight.
- the cycle is already for the material feed stopped and the speed of the conveyor belt 4 is after closing the flaps 9 to the optimized conveying speed switched, bringing the Vor colllvorgang and thus the new weighing cycle begins. So while the Vor colllraum 8 or 80 is already filled with material, the persists Weighing device with weighing container 10 in the settling time, and after expiration of the same is by opening the weighing container 10 the weighed material dropped onto the mixing belt 12.
- a weighing feeder I, II or III is provided. in the In this case, three components can be mixed. Because the individual proportions of the components are different are large, the filling of the weighing container takes 10 at the customary known filling different lengths, so that the component that determines the largest share, including the longest time needed, so that the other two weighing feeders have finished their weighing process sooner and with the dropping of their Wait for weight on the weighing feeder with the largest amount have to. According to the invention, these three weighing feeders are in their filling speed coordinated so that all cope with three weighings at the same time.
- the target weight curve from the unit curve for each component determined and given to the relevant weighing feeder becomes the speed curve for the fill speed correspondingly reduced.
- the priming is slower, however, filling to the final weight regardless of the Vor colllmaschine can also be maintained, so that the same period as the largest component.
- the specified target weight curve from the unit curve is derived here plays the weighing cycle percentage in the same way as the largest Component. A special setting is not required.
- the unit curve is in each control unit or in specified the control unit of the entire system. So you need it only the desired production capacity or the weighing cycle and the desired final weights for the individual components be entered. Everything else, including optimization the process is controlled by the calculator carried out.
- the controller can also be programmed in the same way be that the discharge of the weighed fiber quantities successively begins and ends one after another, so that always complete Mixing packages arise.
- the weighing feeder III its last weighing on the Discard mix tape 12 and then already stop working.
- the last discharge quantity then reaches the Wiegespeiser II, its component on this last weigh of the weigh feeder III and then ceases its activity.
- the mixing plant is switched off. Same way the start by starting the weighing feeder III and one by one the weighing feeders II and I are switched on.
- the process control was through Presetting a desired target weight curve described after which controls the material supply to the weighing container 10 becomes.
- This target weight curve can also be determined empirically However, it is advantageous, this according to the invention to determine the unit curve.
