Definitions

  • the present invention relates to a textile machine with a plurality of jobs according to the preamble of claim 1.
  • multi-point textile machines such as double-twisting or cabling machines, ring spinning machines, open-end rotor spinning machines, etc. have long been known and various embodiments of such textile machines in numerous patents described in relative detail.
  • Such multi-point textile machines generally have a plurality of identical jobs, which are arranged side by side on both sides of the machine longitudinal axis and the working organs are often driven jointly by machine-length, continuous Endloszugstoff together.
  • the individual workstations are each equipped, for example, with a freely rotatable double-twisting spindle, with a machine-length, circumferential tangential belt being used as the drive means for the numerous double-twisting spindles of these textile machines, arranged at one end of the textile machine via the drive wheel of a machine end side Main drive runs and is guided at the other end of the textile machine via a guide wheel.
  • the described drive arrangement has proven itself in practice, in particular in connection with double twisting machines or cabling machines as well as ring spinning machines, but has the disadvantage that in such a drive arrangement energy is always consumed uselessly if no yarn is produced at a workstation takes place, that is, when at a job, although there is a yarn break or a similar event, the associated double-twisting spindle or spinning spindle is further driven.
  • Jobs with a swivel spindle assembly that is, jobs with a spindle which is designed and arranged so that, if necessary, for example in a yarn breakage, the drive whirler of the spindle can be swung out of the path of the tangential, are for example by the CH-PS 510 753 , the DE-GM 75 29 164 and the DE-PS 24 52 939 known.
  • a swivel spindle assembly in which a rotatably mounted on a pivot pin, which is fixedly fixed to the spindle bank of a multi-purpose textile machine, a manually adjustable pivot bearing arm is arranged, which in turn has a receptacle for freely rotatable mounting a spindle equipped with a drive whorl.
  • the pivot bearing arm is also provided with a locking device, which allows a secure positioning of the pivot arm and thus the Antriebswirtels the spindle in two end positions. That is, in the first end position, the drive whirler of the spindle bears against the tangential belt with a sufficiently high contact pressure, while in the second end position the drive whirler is positioned at a distance from the tangential belt.
  • the DE-GM 75 29 164 describes a pivoting spindle assembly in which in a bearing bore of the spindle spindle rotatably a sleeve is arranged, which is a for
  • the locking device is in turn connected via a Bowden cable mechanically to a yarn feeler, which ensures that the locking device is released in the event of a yarn breakage, with the result that the sleeve is rotated by the spring element in the inoperative position and thereby the drive whorl of the double twisting spindle out of contact comes with the tangential belt.
  • a braking device is activated, which brakes the double twisting spindle to a standstill.
  • a comparable swivel spindle assembly is also by the DE-PS 24 52 939 known.
  • a yarn feeler actuates an electromagnetic switching pulse generator in the event of yarn breakage, the switching pulse then ensures that both the package and the double twisting spindle are stopped. That is, in the event of a yarn breakage of the drive whorl of the double twisting spindle is positioned spaced from the rotating tangential belt. Also in the swivel spindle assembly according to DE-PS 24 52 939 At the same time, the double twisting spindle is simultaneously decelerated to standstill.
  • DE-AS 1 239 966 devices with special belt take-off rollers are known in the art DE-AS 1 239 966 or in the DE 195 49 163 C1 described in relative detail.
  • the DE-AS 1 239 966 describes a twisting machine with jobs whose spindles, as usual, are driven by a rotating machine-tangential belt. In the area of the spindles is also limited rotatably mounted, each a holder mounted, which is equipped with at least one Riemenabheberolle.
  • the holder and thus a Riemenabheberolle, initiated by an associated thread monitor can be rotated by a few degrees so that the Riemenabheberolle lifts the Tangentialriemen from Antriebswirtel the spindle and thus the tangential belt has no contact with the drive whorl of the spindle.
  • a spindle brake is simultaneously actuated electromagnetically, which brakes the spindle to a standstill.
  • a workstation of a multi-purpose textile machine which has a spindle drivable by a tangential belt.
  • a pivot lever is mounted on the spindle bench, which is equipped at the end with a Riemenabheberolle and has an engageable to the Antriebswirtel the spindle brake device.
  • the pivoting lever which is biased by a spring during the twisting operation, in an operative position in which the Riemenabheberolle not abutting the tangential tangential belt can be pivoted in the event of yarn breakage by means of a pneumatic cylinder so that the Riemenabheberolle the rotating tangential belt out of contact with the Antriebswirtel brings, wherein the spindle is simultaneously braked by the braking device to a standstill.
  • the devices described above all have the disadvantage that in the case of a yarn breakage, either the drive whorl of the spindle is pivoted away from the tangential belt, resulting in a reduction of the belt tension of the tangential belt and thus to a deterioration of the run of the multi-point textile machine and thus to quality losses in the yarn produced Threading leads, or that in the event of a yarn breakage of the tangential belt is charged by the use of a Riemenabheberolle with an additional belt tension, which leads to an increased energy consumption of the textile machine and to an increased bearing load.
  • the present invention seeks to develop a textile machine, which does not have the known, not yet solved deficiencies, that is, in which it is ensured that in connection with a yarn break at a job neither the running behavior yet the energy consumption of the multi-point textile machine is adversely affected.
  • the embodiment of the invention has the particular advantage that belt tension changes, especially belt tension changes, as previously unavoidable in connection with a thread break when the whorl taken out of the path of the tangential or the Tangentialriemen was lifted from the whorl, are now automatically compensated immediately. That is, the movably mounted Riemenan horrrollen, each applied by a compensation unit to the tangential, respond immediately to any kind of change of the belt tension such that the operational default path of the tangential is corrected so that in all production conditions of the double twisting spindles always a largely constant torque is transmitted to the double twisting spindles. That is to say, the belt pressure rollers mounted according to the invention ensure a proper operation of a textile machine with a plurality of workstations during the entire twisting operation, in particular with regard to the running behavior of the tangential belt and the energy consumption of the drive.
  • means are provided which detect a variable representing the belt tension of the tangential belt and the compensation units can be acted upon as a function of this variable. That is, there is a control unit which adjusts the belt tension depending on the detected amount, and thus, even if the whorl of a double-twisting machine comes out of contact with the Tangnetialriemen, the belt tension remains constant. At a constant belt tension, the torque acting on the twin-twisting spindles in contact with the tangential belt remains constant.
  • the compensation unit is designed as a pneumatic cylinder, which is preferably permanently exposed to compressed air.
  • pneumatic cylinder can be implemented in a relatively simple manner, a reliable compensation unit, which also, since such pneumatic cylinders are usually large-scale components, is still inexpensive.
  • the Riemenandruckrollen are each mounted oscillating about a pivot axis.
  • the Riemenandruckrollen are permanently acted upon in each case by a first pneumatic cylinder and are at a specifiable contact pressure on the tangential belt.
  • Such storage and control of Riemenandruckrollen is straightforward and reliable to produce, that is, the necessary to install the Riemenandruckrollen invention expenses are within reasonable limits.
  • the pneumatic cylinders forming the compensation units are each connected to a compressed air supply device of the textile machine and that the air pressure in the compressed air supply device can be set in a defined manner via a central energy supply.
  • Such a design allows in a simple manner accurate adjustment and, if necessary, rapid correction of applied by the Riemenandruckrollen on the tangential contact pressure, through which the belt tension and thus the on the double twisting spindles to be transmitted torque is adjustable. In practice, this means that the operational outlay which is necessary in order to always keep the torque to be transmitted by the tangential belt to the double twisting spindles of a multi-purpose textile machine at an optimum level is low.
  • the power consumption of the electric motor drive of the tangential belt is constantly monitored and at a power consumption of the drive that is present during normal operation Power consumption exceeds a predefinable limit, which is usually an indication of an incorrect belt tension of the tangential, immediately the air pressure in the compressed air supply device of the textile machine is readjusted.
  • a predefinable limit which is usually an indication of an incorrect belt tension of the tangential
  • the belt pressure rollers according to the invention are used in a textile machine designed, for example, as a double-twisting or cabling machine, in which the double twisting spindles are each movably mounted on a spindle bank of the double-twisting or cabling machine. That is, the stored Riemenan horrrollen invention are used in multi-point textile machines in which the double twisting spindles, if necessary, each from an operating position in which the whorl of the double twisting spindle is applied with a predetermined contact pressure on the circumferential tangential, can be converted into a non-operating position in which the whorl of the double-twisting spindle is acted upon by a braking device.
  • the double-twisting spindle is mounted freely rotatably in each case in a bearing device which can be positioned in a defined manner by means of an actuator, for example by means of a second pneumatic cylinder (Anspr.11). That is, the bearing device and thus the double-twisting spindle can be easily and safely positioned by means of such a pneumatic cylinder either in an operating position or when needed in a non-operating position, the transfer to the inoperative position, as will be explained in more detail below, for example by a signal a thread key is initiated.
  • the spring-loaded brake shoe of the spindle brake device is additionally activated by a foot brake lever.
  • Such a pedal lever brake allows the operator to shut down the double twisting spindle in case of need at any time, with the triggered by the operation of preciselyhebelbremse thread break or initiated by the thread break signal of a thread scanner then ensures that the double twisting spindle is securely positioned in the inoperative position.
  • the textile machine per machine section function fields of predetermined length, in each of which a predetermined number of double twisting spindles are arranged along with associated Riemenandruckrollen, wherein the installation position of the movably mounted Riemenandruckrollen each by the number of pro Function field installed double twisting spindles results. That is, the belt pressure rollers are each arranged so that the contact pressure of the tangential to the whorls of the numerous double twisting spindles of a function field is largely the same size, with possible pressure losses due to friction losses in the lines through ring lines and large cable cross-sections are compensated.
  • the associated belt pressure rollers are preferably located midway between a pair of twin twisting spindles. That is, in such a functional field, the first belt pressure roller is positioned between the 1st and 2nd double-twisting mandrels, the second belt pressure roller is centered between the 3rd and 4th double-twisting mandrels, the third belt pressure roller is centered between the 5th and 6th double-twisting mandrels, etc ..
  • a uniform contact pressure or a uniform wrap angle of the tangential belt on all whorls of the double twisting spindles of a functional field can be reliably achieved in a relatively simple manner.
  • An even number of double twisting spindles has the advantage that a relatively large number of double twisting spindles can be positioned on a functional field of predetermined length, wherein the double twisting spindles in turn have a size which is suitable to advantageously process most of the feed bobbins customary in the textile industry.
  • the odd number of double twisting spindles also has the advantage that a number of double twisting spindles can be positioned on a functional field of predetermined length, which have an oversize. That is, in this way, nine "oversized” double twisting spindles can be installed on a functional field instead of ten "normal” size double twisting spindles.
  • Such "oversized” double twisting spindles are suitable for processing also bobbins whose diameter significantly exceeds the diameter of "normal" feed bobbins.
  • the textile machine designed as a double-twisting machine has for activating the further pneumatic cylinder which positions the double-twisting spindle and a third pneumatic cylinder with which the coil frame can be raised via a switching device, preferably works pneumatically.
  • the pneumatic switching device has a valve which can be activated in the event of a yarn break, for example by a signal of a yarn feeler.
  • This activated by the thread switch valve is also functionally connected to a first, pneumatically controllable directional valve, to which both the pneumatic cylinder for positioning the double twisting spindle, and a second pneumatically controllable directional control valve for actuating the pneumatic cylinder for lifting the coil frame are connected, that at Fracture the affected workstation is automatically stopped immediately.
  • the valve which is in blocking position during twisting operation is mechanically opened, that is, switched to passage, which triggers a switching operation in the sense of "valve open" at the first pneumatic switchable directional control valve, whereby the double twisting spindle at the bearing device activating attacking second pneumatic cylinder and the double twisting spindle is moved to the inoperative position.
  • the second pneumatic directional valve is switched to passage, with the result that the creel is raised.
  • the Fig. 1 schematically shows a side view of two work stations 2 designed as a two-ply twisting or cabling machine textile machine.
