Definitions

  • the invention relates to a method for mixing textile fibers according to the preamble of the first claim and a device according to the preamble of claim 25.
  • the previous methods and devices for mixing consist either in that fiber bales from different provenances are placed in a row and removed by means of a removal device which moves back and forth over them, by removing fiber flakes from the surface and transferring them to a means of transport, or in that parts of fiber bales are lifted manually or mechanically and fed one after the other on a conveyor belt to an opening machine, in which these parts are broken up into fiber flakes and transferred to a means of transport.
  • Such means of transport can be mechanical or pneumatic and convey the fiber flakes into so-called mixing boxes, in which the delivered fibers are filled in as a flake mixture.
  • the fiber flake mixture is placed on a collective transport at different speeds in order to obtain a doubling effect in order to aim for a homogenization of the fiber flake mixture.
  • the disadvantage of the first-mentioned removal and mixing process is that the mixture, due to the stationary rows of bales, is removed until the finished removal such a series is unchangeable, so that the mixing ratio remains the same during this entire time, while the second removal and mixing method additionally exhibits the imprecision of the quantity removed.
  • the mixing components are variable components which can be controlled at any time and in that the percentage of each component, in order to achieve the fiber properties of the mixture mentioned, is automatically optimized, taking into account the fiber properties of the individual components, and automatically if the predetermined fiber properties of the mixture deviate is corrected.
  • fiber properties which are determined beforehand by taking samples from the fiber bales, can be mixed to the desired extent in order to obtain the desired properties of an intermediate product, for example a card sliver or an end product, for example a yarn.
  • FIG. 1 shows a number of conveyor belts 1 for receiving fiber bales 2, which are removed by fiber bale removal elements 3.
  • the respective fiber bale removal member moves on stationary rails which are arranged, for example, in the diagonal direction of the fiber bales 2 located on the conveyor belt.
  • Such a device is basically known from the applicant's CH-A-503 809.
  • the device shown and described in the applicant's EP-A-0 327 885 could be used, in which the removal device 3 is opened and closed on a removal device (not shown) which can be moved back and forth along horizontal bales 2 along the bale can be moved, as well as tilted for diagonal removal.
  • the removal rate in both removal devices can be controlled by changing the displacement speed of the fiber bale removal member 3 along the above-mentioned diagonal path, as well as by changing the feed speed of the fiber bale 2 by means of a variable speed of the individual conveyor belt 1.
  • the fiber flakes detached from the removal drum 4 are transported away in a manner known per se by a pneumatic conveying line 5, which is not described further here.
  • the fiber flakes are conveyed into a mixer 6 and mixed therein to form a uniform mixture.
  • the quantities conveyed into the mixer 6 by means of these individual pneumatic conveying capacities 5 are hereinafter referred to as fiber flake components or simply components.
  • Batch mixers or continuous mixers can be used as mixers; depending on the quantities mentioned are individual weight batches (kg) or a running quantity per unit of time (kg / h).
  • the delivery lines 5 in FIG. 1 schematically open directly into the mixer 6, which is also shown schematically, but in practice this can vary depending on the type of mixer.
  • air-fiber separators can be used to separate the respective fiber-air mixture from one another, so that the fiber flakes can fall into the mixer in free fall, while the air can be led into an exhaust air line.
  • Such separators are well known from practice and are therefore not shown here in particular.
  • the stated quantities of the aforementioned individual fiber flake components which are added to the mixer 6 are controlled by a controller 7 on the basis of a control program.
  • Such a control program can be a computer program which has a component mixing program which can be adapted or changed to adapt to changes in the mixture.
  • Another variant would be a digital control per component, in which the performance of the individual components could be selected or changed manually.
  • the functions determining the removal performance of the components are controlled by one or the other controller.
  • pneumatic conveying lines do not have to convey the removed product directly into the mixer, but that mechanical conveying elements can be connected in between, for example conveyor belts.
  • mechanical conveying elements can be connected in between, for example conveyor belts.
  • the fiber air separators mentioned place their fiber product in such mechanical conveying elements.
  • Each fiber removal member 3 is connected to the controller 7 via a control line 8 and each conveyor belt 1 via a control line 19.
  • FIG. 2 shows a variant of FIG. 1, but in which the same elements have the same reference numerals.
  • the pneumatic conveying lines 5 do not convey the removed fibers or fiber flakes, also called product, directly into the mixer 6, but into component cells 9, from which the product filled therein is discharged by means of a discharge device 10 and into the mixer 6 by means of a subsequent metering device 11 is given.
  • the discharge rate from the individual component cells 9 is controlled by a controller 7.1, which controls the individual metering devices 11 or, as a variant, the discharge devices 10 by means of control lines 12.
  • the metering devices 11 can each be controlled by means of a control line 13 via the dispensing devices 10 in order to coordinate the dispensing with the metering.
  • the discharge apparatus could also be controlled directly by the controller 7.1.
  • the component cells 9 are filled by the elements 1 to 5 already mentioned for FIG. 1, the use of two fiber bale rows, each with the elements 1 to 4, being chosen only as an example. In practice, more than two rows of fiber bales or just a single row per component cell 9 could also be selected. Such a decision depends on the number or mix of provenances per row of bales, which are to form a mixed component to be placed in a corresponding cell 9.
  • the filling of the component cells 9 is controlled, for example, by full-level detectors 14 provided in each cell and by vacancy detectors 15 by means of a controller 16.
  • the controller 16 is for the Back and forth movement of the removal elements 3 by control lines 17 each connected to the fiber bale removal elements 3 and by control lines 18 each to the drive motors of the conveyor belts 1.
  • FIG. 3 shows a further embodiment in which the same elements already shown and described with FIG. 2 have the same reference numerals. This applies to the fiber bales 2, the component cells 9, the discharge apparatus 10, the metering apparatus 11, the mixer 6 as well as the control 7.1 and the control lines 12 and 13.
  • the fiber bales 2 which are here directly on the floor, these are also set up in groups which correspond to the respective provenance of the fiber bales.
  • the removal takes place by means of a mobile fiber bale removal device 20, which runs along the fiber bale groups and removes fibers or fiber flakes from the surface thereof.
  • a mobile fiber bale removal device 20 which runs along the fiber bale groups and removes fibers or fiber flakes from the surface thereof.
  • Such a device is known in the spinning industry under the name "Unifloc" and is sold worldwide by the applicant.
  • This fiber bale removal device 20 conveys the removed fibers in a manner known per se via a pneumatic conveying line 21 into the corresponding component cells 9.
  • This controller is connected to the fiber bale removal device 20 via a control line 24 and controls the removal of fiber flakes from the corresponding fiber bale groups for the filling of the corresponding component cells 9.
  • the fiber bale removal device 20 has a fiber bale removal member 23, known per se from the Unifloc, which removes the fibers from the bale surfaces by means of a removal drum (not shown) rotating therein.
  • the fiber bale removal member 23 can be rotated by 180 ° indicated by the arrow M in such a way that the fiber bale removal member can remove the fiber bale group 2 on the opposite side. This makes it possible that either one of the opposite fiber bale groups is used as a reserve fiber bale group or that with an automatic, aforementioned possibility of rotation of the fiber bale removal device 20, both opposite bale rows can be removed with a predetermined variation.
  • FIG. 4 shows a variant of FIG. 3, so that the elements already described and shown with FIG. 3 have the same reference numerals.
  • control is identified with 22.1 instead of 22, since it means that four individual fiber bale removal devices 20 are to be controlled separately by means of the corresponding control line 24.
  • a pneumatic conveying line is provided for each fiber bale removal device 20, which is accordingly identified with 21.1 instead of 21 and each opens into a component cell 9.
  • FIG. 5 shows an arrangement similar to FIG. 1, in which instead of the single conveyor belt 1 per bale group of FIG. 1, a conveyor belt 30 with a purely conveying function and a conveyor belt 31 with conveying / weighing function, per fiber bale group, is provided for each bale group.
  • the weighing function of the latter conveyor belt can be provided, for example, by supporting the axes of the deflecting rollers of the conveyor belt 31 on pressure sockets 32 known per se, each of which emits a signal 33 corresponding to the weight, each of which via a control line 33 to a control unit processing the signals 7.2 is forwarded.
  • the processing of the above-mentioned signals consists in the control 7.2 working out the control signals therefrom which controls the motors of the conveyor belts 30 and 31 mentioned above and the removal elements 3 via control lines 34.
  • controller 7.2 controls the fiber removal elements 3 and the conveyor belts 30 and 31 at predetermined speeds in order to remove fibers from the fiber bales 2, which are conveyed into the mixer 6 by means of pneumatic conveyor lines 5.
  • Each fiber bale removal member 3 of the individual fiber bale groups feeds a predetermined amount controlled by the control 7.2 into the mixer 6.
  • This predetermined amount to be removed (kg / h) per bale group is determined by the respective weighing conveyor belt 31 or monitored by the pressure cell weighing conveyor belt 31/32 and converted into signals and output to the control system via control lines 33. If the quantity (kg / h) removed per fiber bale group does not match the specified quantity, the control adjusts the quantity to be removed until it matches the specified quantity.
  • measurement is always carried out via the measuring device 32 when the fiber bale removal member is at a standstill for a brief moment at the turning point of the back and forth removal path.
  • the fiber bale removal member 3 always moves back and forth on the same path, essentially lying in the diagonal of the fiber bale to be removed, or up and down.
  • the amount (kg / h) of the fibers to be removed from the bales is generated by means of the feed speed of the conveyor belts 30 and 31 and the removal member 3.
  • the controller 7.2 can be an electronic controller based on the analog technology or a microprocessor, by means of which the different quantities removed per bale group can be set and adapted by the signals of the control lines 33 and input signals explained later.
  • FIGS. 6 and 7 show a weighing system similar to FIG. 5, FIG. 7 being a plan view of FIG. 6, corresponding to the direction of arrow A.
  • this is a number of bale rows or bale groups, which are arranged next to one another and each form a mixing component.
  • the fiber bales 2 each lie on a conveyor belt 40 and an adjoining one Weighing conveyor belt 41.
  • Each weighing conveyor belt 41 can be supported, analogously to the weighing conveyor belt 31 of FIG. 5, on load cells 42, from which a signal corresponding to the weight is output to a controller 44 by means of a control line 43.
  • the fiber bales 2 located on the weighing conveyor 41 are removed by a fiber bale removal device 48 in accordance with EP-A-327 885, which has already been mentioned in connection with FIG. 1.
  • the difference essentially consists in a long fiber bale removal member 49, which extends over the predetermined number of bale rows, with a removal drum 51 which removes fibers from all the bale rows shown in FIG. 7 at the same time.
  • the fiber removal member 49 removes in an oblique removal path which essentially corresponds to the diagonal of a predetermined number of fiber bales 2 lined up, for example as shown in FIGS. 6 and 7, of four fiber bales 2.
  • the fiber material removed by the fiber removal member 49 is conveyed in a pneumatic conveying line 50 which according to the invention opens into a continuous mixer 45.
  • the delivery line 50 can open into a separator (not shown), which discharges the product into the mixer 45.
  • the fiber bale removal device 48 is controlled by the controller 44 via the control line 46 with respect to the driving speed.
  • Another control line 47 is used to control the drive motors of the deflection rollers of the conveyor belts 40 and 41.
  • each deflection rollers of the conveyor belts 40 and 41 (not particularly marked) of each bale group have a separate drive motor, that is to say that each motor has a control line 47 for the control 44 separately.
  • the controller 44 controls the back and forth movement of the fiber bale removal device 48 along the bales located on the weighing conveyor 41 and the up and down movement of the fiber bale removal member 49 on the device 48 during the aforementioned back and forth movement, so that the fiber bales as in FIG Fig. 6 shown in an inclined, substantially the diagonal ver four bales 2 corresponding direction are removed.
  • This removal movement always runs in the same path and at a predetermined speed, so that the removal quantities (kg / h) of the individual fiber bale groups can be selected differently by the individual feed speeds of the conveyor belts 40 and 41.
  • These different feed speeds of the individual bale groups correspond to a removal program different amounts to be removed (kg / h) of the individual bale groups in order to obtain the mixture mentioned.
  • the drive motors for the conveyor belts 40 and 41 are drum motors which are installed in the deflection rollers of the conveyor belts.
  • Such drum motors can be operated by means of frequency inverters at different frequencies, that is to say driven at different speeds, which is a component of the controller 44.
  • the controller 44 can be an analog or digital controller by means of which the quantities of the individual components are controlled. These quantities are corrected by means of the pressure sensor signals, which are input through the control line 43 of the control 44, and the individual component quantity does not correspond to the target specification.
  • FIG. 8 shows an extension of the previously described method, in which it is shown that, after the mixer 6, the product coming from this mixer is put into a so-called blowroom 60, in which cleaning machines known per se are used.
  • the blowroom 60 can contain so-called coarse cleaning machines 61 and fine cleaning machines 62. This blow room, like the previous one, is only shown schematically.
  • the card 63 following the blowroom which can be a card known per se, for example the card C4 distributed worldwide by the applicant.
  • This card 63 is provided with a controller 64 which is known per se and which controls the card functions among other functions also has the function of ensuring the uniformity and the amount (kg / h) of the card sliver.
  • the card sliver is checked by a color sensor 65 and by a sensor 66 for measuring the fiber fineness.
  • the color sensor 65 outputs a signal 67 corresponding to the color of the card sliver and the sensor 66 for measuring the fiber fineness a signal 68 corresponding to the fiber fineness to the control devices 7 mentioned in connection with FIGS. 1 to 7; 7.1; 7.2; 44, which each control the control of the individual fiber components.
  • Another signal 81 corresponding to the card sliver quantity (kg / h) is also input by the card control 64 into the controls 7; 7.1; 7.2; 44.
  • the product discharged from the mixer 6 is conveyed to the blowroom 60 via a conveyor system 69 and to the card 63 from the blowroom 60 via a conveyor system 70.
  • Such conveyor systems can be mechanical or pneumatic, it is also known per se that conveyor systems exist between fine cleaning and coarse cleaning machines.
  • the method according to the invention is likewise not restricted to a single blowroom 60 and a single card 63 after the mixer 6, but rather a plurality of blowrooms 60 and a number of cards 63 can be loaded with the product of the mixer 6 either after the mixer 6, or if a blow room after the mixer 6 is provided, several cards 63 can be loaded with the product of the blow room 60.
  • a color sensor 65 and / or a sensor 66 for measuring the fiber fineness can optionally be provided after each card, or there is also the possibility if several cards process the same product that only one so-called guide card has these latter two test devices .
  • FIG. 9 shows the possibility of providing the blowroom 60 between the fiber removal and the component cells 9, so that an already cleaned fiber material in the component cells 9 is available for the mixture.
  • the conveying device from the fiber bale removal device 20 to the blowroom 60 basically corresponds to the pneumatic conveying line 21, whereby in this case too pneumatic conveyance is not mandatory but can be mechanical.
  • the conveyor between the blowroom 60 and the component cells 9 can also be a pneumatic conveyor line, as indicated by 21, but it can be any conveyor system.
  • the method according to the invention is not restricted to any conveyor system.
  • blowroom 60 is not restricted to the combination with the arrangement from FIG. 3. It goes without saying that fiber components of all the arrangements shown in the figures, with the exception of FIGS. 6 and 7, can first be cleaned and then get into the mixer 6. It is only a matter of effort, since a cleaning shop must be provided for each of the components in FIGS. 1, 2, 4 and 5.
  • FIG. 10 shows a variant of the method of FIG. 9 in that the blow room is divided into a rough cleaning with the cleaning machines 61 and one into a fine cleaning with the fine cleaning machines 71, each of which is preceded by a storage container 72 (for the sake of simplicity only one is marked) is.
  • the fine cleaning machines 71 are started or stopped by a controller 73, namely stopped on the basis of a vacancy detector 74 and started on the basis of a full detector 75 (only one identified). These full and vacancy detectors emit their signals to the control 73 via the lines 76 and 77.
  • the coarse cleaning machines 61 are loaded by means of a fiber transport 78, which can correspond to the pneumatic conveying line 21 from FIG. 9 or to any fiber conveying known per se.
  • the fine cleaning machines each pass their products on to a component mixing cell 9, as has already been described for FIGS. 2 to 4 and for FIG. 9.
  • the components are cleaned individually, accordingly, the vacancy detectors 15 of the individual component cells 9 request the removal of fibers from the corresponding fiber bale group a or b or c or d in order to clean these removed fibers in the coarse cleaning machine and pass them on to the corresponding storage container 72 , which delivers the specified component to the subsequent fine cleaning machines 71.
  • This product request by the vacancy detector 15 occurs because the corresponding fine cleaning machine no longer supplied a product since the vacancy detector 74 in the storage container 72 had also reported vacancy. Accordingly, the corresponding group a to d continues to be removed until the corresponding fullness indicator 74 reports fullness to the removed component. The corresponding fine cleaning machine can thus be put into operation again until the fullness detector 14 reports fullness again to the corresponding component cell 9.
  • the fiber transport 80 between the mixer 6 and the card 63 can correspond to a fiber transport which is identified and described as 70 in FIG. 8.
  • a mixer 6 can operate several cards, so that the fiber transport 80 transports the product delivered by the mixer to the corresponding number of cards.
