Definitions

  • the invention relates to a method for operating a ring spinning machine according to the preamble of the independent claim, and a corresponding ring spinning machine.
  • Service robots or service carriages that piece threads on ring spinning machines after a thread break are well known. Mention is made here in particular of the service robot from EP 394671 A2 .
  • This service robot moves along a row of spinning stations, detects thread breaks, and then attempts to eliminate the detected thread breaks.
  • the belt driving the spindle is initially lifted from the spindle by means of a special spindle braking device, and the spindle is subsequently stopped.
  • an auxiliary thread is used.
  • One end of the auxiliary thread is fastened to a winder that is movable around the spinning cop in order to then be wound around the spinning cop.
  • the auxiliary thread is subsequently threaded through the ring traveller and the thread guide and brought into the area of the outlet of the drafting system.
  • the spindle and thus also the spinning cop are driven once again, and the auxiliary thread is brought into the path of the drawn roving so that the auxiliary thread is twisted with the drawn roving.
  • DE 3932727 discloses a method for eliminating a thread break on a ring spinning machine. It is provided that an auxiliary thread that is carried along by a service carriage is loosely placed on the cop of a spindle and pieced to a slub that is delivered by a drafting system. It is likewise known from DE 3932727 that during the operation of the service carriage, the spindle actuates a brake by means of an actuating element and/or the drive is interrupted.
  • WO 2009/132469 relates to a ring spinning machine having a single-spindle drive.
  • the workstations may contain sensors or other means for determining parameters at the workstations.
  • the current or power consumption of the spindle drive or the spindle speed may be determined by the spindle drive electronics system, optionally by use of sensors.
  • Information concerning thread breaks or thread tension may be ascertained from these measuring data.
  • the spindle in question or the drive associated with it may be autonomously shut down by the spindle drive electronics unit or the section electronics unit.
  • DE3524073A1 discloses a method and arrangement for the automatic repair of yarn breaks by means of a piecing carriage on a spinning machine. Before each thread piecing attempt is carried out, an error check is carried out at the relevant spinning position to determine whether there is an error which makes it impossible to eliminate the thread break at the relevant spinning position. If such an error is detected, the yarn piecing test is omitted. The error check is carried out from the piecing carriage, wherin all error detection means are arranged at the piecing carriage.
  • the EP0419828A1 shows a method as well as an operating robot for operating a ring spinning machine. After each doffing process, an integral doffer is used to check the spinning positions to see whether a spinning tube is attached to the respective spindle or not. In addition, the position of the respective spinning sleeve is also checked. If a spinning tube is missing or if the spinning tube mounted on the spindle in question does not have the desired position, a roving stopper device is automatically activated for the spinning position in question. For troubleshooting, the operating robot only operates spinning positions whose roving stopper device is not actuated.
  • DE4312026A1 reveals a method and a device for operating a spinning machine with several spinning positions, in particular a ring spinning machine, and with a sensor system suitable for detecting the spinning position conditions. Three different states “yarn running”, “yarn break” and “stationary yarn” are distinguished by evaluating the sensor signal.
  • EP1712664A2 discloses a machine control method for a spinning machine having a plurality of spinning units that are arranged in parallel in a longitudinal direction of the spinning machine includes the steps of providing a camera to a traveling body that is movable in the longitudinal direction of the spinning machine so that the camera faces toward the spinning machine; moving the traveling body along the spinning units at certain intervals for patrolling the spinning machine; shooting the spinning unit by the camera during the patrol of the traveling body; storing shot data of the spinning unit that is shot during the patrol of the traveling body in a memory; and displaying on a display the shot data as visual data or as analysis data obtained from the shot data.
  • the spindle drive electronics system unit or section electronics system unit in question may be designed, for example, for autonomously carrying out one or more of the following functions: thread break detection, slub stopping, single-spindle drive control, thermal monitoring of the single-spindle drives, slubbing switchover, spindle speed measurement, thread tension measurement, communication with an associated automatic traveller, operator guidance of spinning stations, malfunction displays, hand switches, and/or other sensor functions.
  • a thread break and/or increased thread tension are/is preferably determinable by the particular spindle drive electronics system unit via the current or power consumption of the electric motor drive associated with the particular workstation.
  • the machine control unit itself carries out, for example, the start-up and/or process control, which may be effective, for example, for normal shut-off as well as for an emergency shut-off in the event of a power failure.
  • the object of the invention is to provide a method for operating a service carriage with which the reliability and possible applications of the service carriage may be increased.
  • the object is achieved by a method for operating a ring spinning machine having a service carriage according to the preamble of the independent method claim, in that a status of the spinning station having the thread break is determined in a module, and based on the determined status a decision is made as to whether the thread break can be eliminated by the standard program of the service carriage.
  • the service carriage advantageously does not approach the spinning station. Hence, this keeps the service carriage available for spinning stations that have thread breaks which can be eliminated by the standard program. Consequently, downtimes of spinning positions that can be restarted by the service carriage using the standard program can be reduced, as the service carriage does not work unsuccessfully at spinning stations which actually require special programs. This allows a significant reduction of total downtimes and thus an increase in production capacity as well as decrease in energy consumption. At the same time, it enables a higher number of spinning positions to be handled by one robot.
  • the service carriage may approach the spinning station and determine the status of the spinning station. In this way, unnecessary attempts to eliminate a thread break are avoided.
  • the service carriage may also approach the spinning station and determine the status of the spinning station after a first pre-assessment of the status has already been performed by a special module as described herein. For example, only a rough preliminary analysis may be carried out by a sensor (as subsequently described in more details) installed at a certain spinning position in order to detect certain types of defects that cannot be treated with the standard program.
  • the service wagon may approach the spinning position and perform a second more sophisticated analysis using one or more additional types of sensors (as described herein) in order to determine whether the thread break can be eliminated by the standard program of the service carriage.
  • This can further reduce the time required for unsuccessful runs of the standard program for elimination of thread breaks.
  • it allows to combine relatively simple and cost-efficient sensors arranged at the spinning stations with a more sophisticated sensor system arranged at the service carriage. This allows to decrease spindle downtimes and at the same time a highly reliable determination of thread breaks that can be eliminated by the standard program with relatively low costs for sensors.
  • the ring spinning machine is informed of the determined status of the spinning station, this status is shown on a display, and/or an operator is called to place the spinning station back in operation.
  • an operator may e.g. be called to place a spinning station back to operation if it was determined that this can not be done by the standard program.
  • an operator may e.g. be called to place a spinning station back to operation if a high number of yarn breaks has occurred.
  • the spinning station is monitored by a camera and/or a microphone, the result is transmitted to the module, and the status is determined in the module.
  • a camera and/or a microphone the result is transmitted to the module, and the status is determined in the module.
  • one or multiple of these means are arranged at each spinning station.
  • one or multiple of these means may be used to monitor multiple spinning stations.
  • a camera may be used in order to monitor multiple spinning stations.
  • the spinning station may advantageously be recorded by at least one camera, and the status of the spinning station determined by image analysis. It is possible for the spinning station to be recorded in sections by different cameras, the result transmitted to the module, and the status determined in the module. It is advantageous when the recorded status images are stored and used in the image analysis of the status of the spinning station. Thus a particualry reliable determination of yarn break that can be eliminated by the standard program becomes possible.
  • the accuracy of the status analysis during operation may be improved by presenting and demonstrating actual examples of statuses to the service carriage in a type of training. This is particularly advantageous when a ring spinning machine is converted or modified, and the conditions at the spinning stations have changed. This training may advantageously improve the quality or speed of the status analysis.
  • the module may also contain self-learning functions so that the status analysis may be adjusted for altered environmental conditions such as production speed (delivery, rotational speed), yarn color, lighting, etc.
  • the service carriage and/or the ring spinning machine may advantageously be retrofitted with the module for determining the status. Hence, retrofitting of existing machines with such a system becomes possible.
  • the object is further achieved by a ring spinning machine having a service carriage according to the preamble of the independent device claim, in that a module is present for determining the status of the spinning station, and based on the determined status ascertains whether the thread break can be eliminated by the standard program of the service carriage.
  • the module may advantageously be designed to inform the ring spinning machine of the status of the spinning station, to show the status on a display, and/or to call an operator. Hence, a particularly economical operation of the ring spinning machine becomes possible and the amount of manual surveillance by the operator can be reduced.
  • At least one camera and/or at least one microphone are/is present which are/is connected to the module in order to determine the status of the spinning station. These means may be interconnected with the module directly or indirectly. Hence e.g. information acquired by a camera may be processed by an image registration sytem that may be part of the module or may be separated from the module but provide information to the module.
  • a memory may advantageously be present for storing status images and comparison images that are recorded with a camera, and for using same in an image analysis of the status of the spinning station.
  • the module may advantageously determine at least one of the following statuses:

  • various operating states at the spinning station are then recognized.
  • a spinning station that is running without problems during piecing, or images with corresponding statuses that are to be determined, could be used as a comparison image. Many of the statuses mentioned above may be determined by image recognition.
