Definitions

  • the present invention relates to a spinning machine with a large number of working stations arranged next to one another in the longitudinal direction of the spinning machine on at least one longitudinal side between two front ends of the spinning machine, each of which has a plurality of working elements for producing and winding up a yarn, the working elements comprising at least one feed device, a spinning chamber, include a take-off device and a winding device, with drives for driving the working elements and with a suction device for generating a negative pressure at the working points.
  • the DE 101 45 443 A1 has already suggested using several fans to improve the vacuum supply on a compression spinning machine, which has a particularly high vacuum requirement compared to rotor and air-jet spinning machines.
  • the DE 10 2006 029 056 A1 describes a rotor spinning machine with an intermediate frame arranged between the work stations. At least the central drive for the yarn traversing devices and the device for generating the negative spinning pressure should be arranged in the intermediate frame. This reduces both the required length of the thread guide rods and that of the vacuum channels for distributing the spinning vacuum to the work stations, since these only have to extend from the intermediate frame to one of the two machine ends. Problems with the central drive of the thread guide rods due to elongation and torsion, which increase with machine length, can be reduced in this way and the vacuum supply can be improved.
  • the DE 196 12 707 A1 describes a spinning machine in which a cooling duct extending over the length of the arrangement of the spindle motors is provided for cooling the spindle motors.
  • the cooling duct can also be subdivided, in which case each of the partial ducts can be assigned its own fan arrangement with a motor.
  • the JP S57 126468 U also shows an air-jet spinning machine in which a suction channel is provided, which opens into two suction points at each spinning station.
  • a spinning machine is also known in which the take-off devices of each spinning device are provided with an individual drive.
  • the EP 0 634 506 A1 shows a rotor spinning machine in which individual dirt separation is provided on the spinning devices below the opening roller.
  • the dirt chamber of the individual dirt separator is connected to a vacuum source via a dirt suction line and a filter chamber.
  • the machine is designed as a double-sided machine, in which there is a separate coil conveyor belt for each side of the machine.
  • the DE 42 31 958 A1 describes a ring spinning machine, which shows a changing device with a magazine for reserve bobbins.
  • the DE 10 2004 016 797 A1 describes a spinning machine in which a vacuum duct for transmitting the vacuum to the spinning positions is divided into several flow-tight separate line segments. It should be advantageous if the multiple line segments are connected to a single, central vacuum source. The consumers located closer to the vacuum source are served by a shorter line segment and the consumers located further away from the vacuum source are served by a longer line segment. In this way, the suction air in the line segment that leads to the more distant consumers should run undisturbed and not be influenced by the branches to the suction points of the closer consumers. This is to reduce flow losses.
  • the DE 10 2007 053 467 A1 addresses the problem that when multiple suction nozzles are in operation, sufficient vacuum can still be provided. This is solved in that, in addition to a first vacuum source only when needed, ie when several suction nozzles are in operation, a second vacuum source is switched on, which suctions the same vacuum channel.
  • the object of the present invention is therefore to propose a spinning machine which allows the arrangement of a particularly large number of work stations on the spinning machine and at the same time enables the machine to be operated economically.
  • a spinning machine has a large number of work stations arranged next to one another in the longitudinal direction of the spinning machine between two front ends on at least one longitudinal side of the spinning machine.
  • the work stations each have a plurality of work elements for producing and winding up a yarn, these comprising at least one feed device, one spinning chamber, one take-off device and one winding device.
  • the spinning machine has drives for driving the working elements and a suction device for generating a negative pressure at the working points.
  • the suction device contains at least one vacuum source and at least two separate vacuum channels, which extend in the longitudinal direction of the spinning machine over only part of the work stations. Furthermore, each work station has an individual drive as a drive for the extraction device.
  • the individual drive is preferably designed as an individual electric drive, but could also be a pneumatic drive.
  • an individually driven take-off device enables the individual work stations to be stopped and started up in a controlled manner and the draft to be set individually. In particular when piecing on an air-jet spinning machine, the draft can be precisely adjusted by a controlled, controlled raising of the take-off device, so that piecings can be produced with high quality.
  • the spinning machine has at least two separate vacuum sources, each of the vacuum sources being connected to a separate vacuum duct. It is advantageous if at least one of the vacuum sources is arranged on at least one of the two front ends of the spinning machine. In this case, at least one further vacuum source can be arranged either in a central area between the two front ends of the spinning machine or on the other front end of the spinning machine. However, it is also conceivable to arrange at least two vacuum sources in the central area of the spinning machine, which then each have spinning positions between one of the ends of the spinning machine and the central area.
  • At least one vacuum source at each of the two ends of the spinning machine or, particularly in the case of very long machines, at least one vacuum source at each of the two ends and at least one additional vacuum source in a central region of the spinning machine.
  • the overall performance of the at least two separate vacuum sources can be lower than it would be in the case of a single vacuum source with a continuous vacuum channel.
  • the vacuum sources are preferably arranged in a frame which is either located at a front end of the spinning machine or is provided as an intermediate frame in the central area of the spinning machine. This makes it possible to accommodate the central drives of the spinning machine and the vacuum source in a common frame. However, it is also conceivable to arrange the vacuum sources in a separate housing or frame.
  • the spinning machine with individually driven take-off devices and with a divided vacuum supply with at least two vacuum sources therefore enables particularly energy-saving and cost-effective operation due to the optimal arrangement and drive form of these two components, which are important for energy consumption.
  • the divided vacuum supply also makes it possible to provide a greater vacuum level overall at the spinning positions, so that better spinning stability and better yarn stability can be achieved. Accessibility to the vacuum sources and their filter boxes, in which extracted impurities and waste are collected, is not impaired. This also makes maintenance and supply and disposal by operating personnel or by automatic maintenance devices easier, which also contributes to the economical operation of the machine.
  • the work stations each have at least one suction point, which is arranged either in the area of the spinning chamber or in the area of the feed device.
  • a rotor spinning machine has a suction point in the area of the spinning chamber. Since rotor spinning machines have a particularly high vacuum requirement due to the spinning vacuum required for the spinning process, the subdivided vacuum supply with a vacuum source at each end is particularly advantageous in such machines. A sufficient vacuum level can also be achieved on long machines with more than 500 work stations, even at the work stations that are remote from the vacuum source. Since the work stations are evenly supplied with negative pressure, quality problems in the yarn produced can also be avoided.
  • the spinning machine is an air jet spinning machine.
  • This has, for example, a suction point in the area of the spinning chamber, so that fibers that are not bound into the yarn are sucked off, which could otherwise lead to a blockage of the spinning element and impair the quality of the yarn produced.
  • the air-jet spinning machine can have at least one suction point in the area of the feed device in order to transport emerging fibers away and to avoid lap formation. It is therefore also particularly advantageous if, in the case of an air jet spinning machine, the work stations each have at least one first suction point in the region of the spinning chamber and at least one further suction point in the region of the feed device. Due to the divided suction device, energy-efficient fans with a lower output can also be used in such a spinning machine with a higher vacuum requirement per se.
  • the vacuum sources each have a fan and a drive for the fan.
  • the drives of the vacuum sources can be controlled by a central control device of the spinning machine. It can this involves at least two drives and fans of the same type. However, if a different vacuum level is required in the at least two vacuum channels, for example for different spinning applications, or the vacuum channels are of different lengths, different fans and drives can also be used. It is also advantageous that each fan is assigned its own filter box, so that the waste collected in it can be disposed of at both ends of the machine. A rapid clogging of the filter and a resulting drop in vacuum can also be avoided in this way.
  • the spinning machine For energy-saving operation of the spinning machine, it is advantageous if at least 20%, preferably at least 30%, particularly preferably at least 40% of the work stations arranged next to one another on at least one longitudinal side in the longitudinal direction of the spinning machine are connected to each of the at least two vacuum channels. This ensures that the pressure losses in the vacuum channels are kept within low limits and that the individual work areas are evenly supplied with vacuum. It is also advantageous if the two vacuum channels are of the same length and/or the same number of work stations are connected to the two vacuum channels. Compared to a single, machine-long vacuum channel, the vacuum channels can be reduced to about half the previous length, which means that the pressure losses can be reduced in an optimal manner.
  • the at least two vacuum channels are arranged in alignment one behind the other in the longitudinal direction of the spinning machine.
  • the two vacuum channels run at least partially parallel to each other in relation to the longitudinal direction of the spinning machine. This makes it possible to connect individual workstations to one or the other vacuum channel as required, thereby making the vacuum supply flexible.
  • each work station has an individual drive, in particular an individual electric drive for the feed device.
  • an individual drive in particular an individual electric drive for the feed device.
  • at least one pair of delivery rollers driven by a single drive is provided as the feeding device, so that the amount of fiber material fed can also be precisely matched to the prevailing conditions here.
  • the feed device is designed as a drafting device, it is advantageous if this is designed by means of an individual drive for each spinning station.
  • the above-mentioned pair of delivery rollers is part of the feeding device, so that all rollers of the feeding device are driven by a common individual drive for each spinning position.
  • each of the two longitudinal sides is also supplied with negative pressure separately.
  • two vacuum sources are provided at each of the two ends, which are each connected to a separate vacuum channel, which in turn extends only over part of the work stations arranged next to one another in the longitudinal direction.
  • the winding devices are each driven by means of an individual electric drive.
  • the work stations also have their own yarn handling units, long waiting times for maintenance or repair of broken yarns can also be avoided, which in turn enables an increase in productivity.
  • the other working elements are each driven on one longitudinal side by means of central drives. Since these rotate at comparatively low speeds, the losses are still in a range in which a central drive is economical, even on longer machines with a particularly high number of spinning positions, for example more than 500 spinning positions on rotor spinning machines or more than 120 on air-jet spinning machines proves.
  • a semi-automatic rotor spinning machine operation is also particularly economical if the opening devices are also driven by a central drive.
  • similar, centrally driven working elements form at least two groups on one longitudinal side, with a separate central drive for driving one of the two groups being arranged in each of the two frames at the front ends.
  • This in turn can shorten the usually machine-long drive means to up to half the otherwise required length. This not only reduces problems caused by torsion and elongation, but also reduces losses due to flexing work in the belts.
  • the at least two groups per longitudinal side of the spinning machine can each include the same number of work stations or different numbers. It is advantageous if, in turn, at least 20% of all work stations on one long side are each assigned to a central drive.
  • the spinning machine has at least two bobbin conveyor belts arranged one behind the other in the longitudinal direction of the spinning machine. High losses also occur on these, which can be reduced by using two shorter belts, each with smaller drives, instead of a single belt with a large drive.
  • the spinning machine has an intermediate store for empty tubes, in order to shorten the delivery routes and thus also the belt running times for supplying empty tubes.
  • deflection rollers of central drives and/or drives and/or storage units for central supply and disposal facilities are arranged in the intermediate frame.
  • the supply of empty tubes can be further facilitated and the delivery times for empty tubes can be shortened if the spinning machine is at each its front ends has a central sleeve store for empty sleeves. These are preferably arranged at a distance from the two frames in order to ensure that the frames can be accessed.
  • the spinning machine has a connection for power supply at each of its two front ends, in particular for a voltage supply for the electrical components and/or for a compressed air supply.
  • the spinning machine has an exhaust air outlet of the suction device at each of its two front ends.
  • a protective discharge can also be provided at both ends of the machine.
  • FIG. 1 shows a schematic representation of a spinning machine 1, which is particularly suitable for arranging a large number of work stations 3 next to one another in the longitudinal direction of the spinning machine 1.
  • the work stations 3 are arranged next to one another between two front ends 2 and each have a plurality of work elements 4, 5, 6, 7 for producing and winding a yarn 31 in a manner known per se.
  • Each work station 3 has a feed device 4, by means of which a fiber material is fed from a storage container 24 to a spinning chamber 5, in which it is spun into the yarn 31.
  • the yarn 31 is withdrawn from the spinning chamber 5 by means of a take-off device 6 and finally wound onto a spool 32 by means of a winding device 7 .
  • the spinning machine 1 has a suction device 8, which serves to supply the work stations 3 with negative pressure and is also provided for removing impurities and waste from the work stations 3, which accumulate during piecing and maintenance of the work stations 3.

Included each of the negative pressure sources 9 is connected to one of the separate negative pressure channels 10, which extend in the longitudinal direction of the spinning machine 1 over only part of the work stations 3.
  • the negative pressure sources 9 are in accordance with figure 1 each at the front ends 2 of the spinning machine 1, in this case each end-side frames 12 are arranged.
  • the negative pressure channels 10 are arranged one behind the other in the longitudinal direction of the spinning machine 1, so that only a small amount of installation space is required.
  • a division 34 between the two vacuum channels 10 can be designed to be fixed or flexible, for example by dividing a continuous channel into two vacuum channels by means of a displaceable diaphragm.
  • each work station 3 is connected to at least one of the at least two vacuum ducts 10 , on the other hand only some of the work stations 3 being connected to each of the vacuum ducts 10 .

In the present case, however, the drives 19 of bobbin conveyor belts 18 are also arranged in the intermediate frame 17 .
  • central drives 23 are provided for the feed devices 4 and for the spinning chambers 5 or spinning rotors 35. These are also only to be understood as examples. Depending on the type of spinning machine 1, other or further working elements can also be driven centrally, or individual drives 11 can also be provided for some working elements.
  • an intermediate store 20 in which a specific number of empty tubes 37 can be stored. It is thus possible to supply the jobs 3 that are further away from the central tube store 30 from the intermediate store 20 and the jobs that are close to the central tube store 30 from the central tube store 30.
  • the empty tubes 37 can be assigned to the individual jobs on at least one longitudinal side of the machine 1 can be delivered by means of a single tube conveyor belt 36 from both the central tube store 30 and the intermediate store 20. In the present case, however, two tube conveyor belts 36 are provided, with the intermediate store 20 being able to be loaded with empty tubes 37 from the central tube store 30 .
  • the productivity of the spinning machine 1 can be further increased as a result, since the waiting times for empty tubes 37 can be significantly reduced.
  • an intermediate frame 17 placed essentially centrally between the front ends 2 can be provided with two vacuum sources 9, which then each have the work stations 3 in the supply areas adjacent to the left and right of the intermediate frame.
  • the work stations 3 in the areas near the front ends 2 are supplied by the vacuum sources 9 provided there.
  • an asymmetrical structure of the spinning machine 1 can also be provided, in which the intermediate frame 17 is arranged between the two front ends 2, but eccentrically.
  • preferably only one vacuum source 9 is arranged in the intermediate frame 17 which, together with a vacuum source 9 arranged in one of the end frames 12, supplies the work stations 3 of the longer machine section.
  • the invention is not limited to the exemplary embodiments shown.
  • each of the groups thus forms its own production group, which is assigned its own central drive 23 and its own vacuum source 9, so that a different product can also be manufactured in each of the production groups independently of the others.
  • the division into at least two production groups by their own vacuum source 9 ensures that a sufficient vacuum is achieved at every point in each of the vacuum channels 10 during operation.
  • the vacuum supply in groups also offers the possibility of setting the vacuum level in the vacuum channels 10 differently according to the intended product or according to the application intended in the respective production groups.
  • a central supply device 21 for empty tubes 37 with at least one central tube store 30 could also be provided at each of the two ends 2 of the spinning machine 1, which improves flexibility in multi-lot occupancy and further reduces the waiting times for empty tubes 37.
