Definitions

  • the present invention relates to a workstation of a spinning or winding machine with a housing, wherein the housing comprises a static frame and at least one movable portion, wherein the at least one movable portion is mounted such that it is movable between an operating position and a maintenance position the section in the operating position covers at least partially at least one fiber extraction and / or at least one electronic component of the workstation and wherein in the maintenance position the at least one fiber extraction and / or the at least one electronic component are accessible to an operator.
  • the present invention relates to a method for operating a workstation of a spinning or winding machine, wherein the workstation comprises a housing comprising a static frame and at least one movable portion, wherein the portion in the operating position at least partially at least one fiber extraction and / or at least concealed an electronic component and wherein in the maintenance position the at least one fiber extraction and / or the at least one electronic component are accessible to an operator, wherein the at least one movable portion is moved from its operating position to its maintenance position for maintenance and / or cleaning purposes.
  • Modern spinning or winding machines are usually built up strongly modular. They consist for example of a large number of similar jobs, which in turn are also made up of individual modules.
  • To exchange items of a job or perform maintenance and cleaning work means are known to make the operator otherwise difficult to access areas of a job accessible.
  • the Workplaces have for this purpose components that can be brought from an operating position to a maintenance position.
  • the object of the present invention is thus to improve the safety of a work station in which a movable housing part, which conceals maintenance-relevant components during operation of the workstation, can be brought from an operating position into a maintenance position.
  • the workstation according to the invention for a spinning or winding machine comprises a housing, wherein the housing has a static frame, for example a frame portion or a frame element, which is fixedly connected to the spinning or winding machine, and at least one movable portion.
  • the movable portion is supported so as to be movable between an operating position and a maintenance position.
  • the section in the operating position at least partially conceals at least one fiber extraction and / or at least one electronic component of the workstation.
  • the at least one fiber extraction and / or the at least one electronic component are accessible to an operator.
  • the section may be formed in one piece or in several parts.
  • the section may be formed as a cover or include such.
  • the section may include modules of the job in whole or in part.
  • the workstation has a sensor which is designed to monitor the position of the movable section relative to the static frame.
  • the senor could be part of a safety circuit of the job and / or the spinning or winding machine.
  • the operation of the job could thus be possible only when the operating position of the section. By stopping the driven moving parts of the workstation (if the section leaves the operating position), the risk of damage to the workplace or the danger to the operating personnel would drop significantly.
  • the possibly hidden from the section in the operating position fiber extraction usually comprises at least one vacuum-pressurized tube by means of which yarn, for example, for the purpose of piecing in a spinning machine, can be sucked.
  • the electronic components mentioned could include, for example, electric motors, printed circuit boards, integrated circuits, power supplies and yarn sensors.
  • a spinning unit is usually used to produce a yarn of fibers, for example, rotor or air spinning or ring spinning are common methods that are used in a spinning unit.
  • a winding unit serves to wind up or rewind a yarn.
  • a thread is guided along the movable portion.
  • a first channel section of the fiber extraction which is arranged, for example, on the frame of the work station, adjoins a second channel section of the fiber extraction, which is arranged on the section.
  • the second channel section could be connected to the first channel section of the fiber extraction by means of a seal, for example a rubber seal, which connects, for example, a plurality of the work stations and a central exhaust.
  • the section by means of a, in particular horizontally extending axis, is pivotally mounted. Moving the section to the operating or maintenance position in this case would be equivalent to rotating the section about the axis.
  • Such a structure offers great stability with little effort for the movement of the section. Since usually many similar jobs in a spinning or winding machine close together next to each other are arranged, but in the halls in which these machines are normally used, large room heights exist, it is particularly advantageous if the axis is horizontal.
  • the maintenance position of the section can thus be selected such that a free space above and / or before the spinning or winding machine is used. A storage by means of a thrust bearing would also be conceivable.
  • the section would also be conceivable to form the section additionally or exclusively separable from the job.
  • the section would be connected in the operating position with the workplace and separated in the maintenance position of the workplace.
  • On a movable storage could possibly be waived in this case.
  • the workstation has a holding element which is designed to fix the section in the maintenance position. This guarantees a safe working of the operating personnel during a cleaning or maintenance.
  • the holding element could for example be designed as a rod, bolt, hydraulic press or counterweight.
  • the retaining element could be firmly connected to the frame and / or the section. A removable design is also conceivable.
  • the workstation has a locking element which is designed to fix the section in the operating position. Inadvertent movement of the section is prevented in this way. Damage to the workplace and a risk to personnel are thereby avoided.
  • the locking element could for example be designed such that it can only be opened when the workstation is at a standstill.
  • the locking element could, for example, comprise one or more magnets, bolts, screws or hooks.
  • the opening and closing of the locking element could be electrically or purely mechanically controlled.
  • the section is advantageously part of a thread withdrawal unit or is designed as a thread withdrawal unit.
  • the thread withdrawal unit is usually located in the transport direction of the thread between a spinning unit and a winding unit or between a supply spool and a winding unit and thus in a position advantageous for the section.
  • maintenance-relevant components for the workplace are usually arranged in this area.
  • the section and / or one or more additional movable sections are components of other modules of the workstation, such as the spinning unit or the winding unit.
  • the thread withdrawal unit and thus possibly the movable section, comprises at least one yarn monitoring unit.
  • Yarn monitoring units ensure the undisturbed operation of the job and a uniform quality of the yarn produced.
  • paraffin unit would be conceivable as part of the thread withdrawal unit and thus possibly of the section. By paraffinating the thread, the further processing is greatly facilitated.
  • the section has a display or a recess for a display.
  • Displays at workstations are usually used to monitor and / or control the jobs and / or the entire spinning or winding machine. Since the display as well as the section are advantageously arranged in an easily accessible for the operator height, it is advantageous if the display is part of the section. If the display is alternatively connected to a static Element of the job is arranged, it is advantageous if the section has a recess for the display.
  • the senor is designed as a magnetic sensor. Magnetic sensors can measure positions without contact and therefore wear-free. In addition, these sensors are resistant to interference, since only magnetizable materials affect the measurement of these sensors.
  • alternative embodiments of the sensor for example as an electrical contact, opto-electrical, inductive or capacitive sensor or ultrasonic sensor would also be conceivable.
  • the senor determines whether the section is in the operating position or not.
  • the design as a binary sensor is cheap and space-saving.
  • the senor comprises a pickup and a switching element.
  • the transducer is meant an electronic component that is measurably responsive to the position of the switching element.
  • the sensor would be a Hall sensor and the switching element would be a permanent magnet.
  • the switching element would be arranged according to the respective other component. A distance of less than 2 cm between the transducer and switching element would be advantageous for an accurate measurement.
  • the spinning or winding machine in which the job is installed, has a movable service unit, it would be advantageous if the section in the maintenance position is not located in a collision space of the service unit. If, due to limitations in the construction of the spinning or winding machine, a collision probability can not be prevented, it would be advantageous to connect the sensor to the control of the service unit that operation of the service unit in the area of a job, the section is in the maintenance position , is prevented.
  • the method according to the invention describes the operation of a workstation of a spinning or winding machine.
  • the job on a housing comprising a static frame and at least one movable portion.
  • the section conceals in an operating position at least partially at least one fiber extraction and / or at least one electronic component.
  • the at least one fiber extraction and / or the at least one electronic component are accessible to an operator.
  • the at least one movable section is moved from its operating position to its maintenance position for maintenance and / or cleaning purposes. It is proposed that the position of the section relative to the static frame be monitored by means of a sensor.
  • the method described allows an objective assessment of the position of the section and thus an increase in safety for man and machine.
  • an operation of the job is only possible if the sensor confirms the operating position of the section.
  • the signals of the sensor are transmitted to a control of the workstation and / or the spinning or winding machine.
  • the signals of the sensor are transmitted to a control of the workstation and / or the spinning or winding machine.
  • the signals of the sensor are transmitted to a control of the workstation and / or the spinning or winding machine.
  • the signals of the sensor are transmitted to a control of the workstation and / or the spinning or winding machine.
  • the signals of the sensor are transmitted to a control of the workstation and / or the spinning or winding machine.
  • the signals of the sensor are transmitted to a control of the workstation and / or the spinning or winding machine.
  • the alarm could be optical and / or acoustic in nature and in particular triggered only during operation of the job.
  • spinning or winding machine used in the method can have one or more of the physical features described heretofore or hereafter.
  • a workstation 1 of a rotor spinning machine is supplied with a fiber material 3 from a spinning can 4 during operation by means of a delivery device 2, which fiber material is dissolved by means of an opening roller 5 into individual fibers. These individual fibers are spun by means of a spinning rotor 6 into a yarn 7.
  • This yarn 7 is withdrawn by means of a yarn withdrawal unit 8, for example via a take-off roller pair 9, possibly checked in a yarn monitoring unit 10 for yarn defects and wound by means of a winding unit 11 on a spool 12.
  • the operator is communicated via a display 24, the status of the job 1.
  • a movable section 13 which is arranged on a static frame 22 of the workstation 1 is, in operating position.
  • a locking element 23 could fix the section 13 during operation of the workstation 1 in the operating position.
  • the section 13 is, for example, part of the thread withdrawal unit 8.
  • the section comprises, for example, the take-off roller pair 9, the display 24 and the yarn monitoring unit 10. Further possible components (not shown) of the section 13 could be thread guide elements or a waxing unit.
  • a sensor 14 monitors the position of the movable portion 13.
  • the sensor 14 may consist of a pickup 15 and a switching element 16.
  • the sensor 14 could be a magnetic sensor.
  • a vacuum-loaded fiber extraction serves to handle the yarn 7, for example during a piecing process.
  • the movable portion 13 is preferably pivotally supported by an axle 18.
  • FIG. 2 shows the job 1 from FIG. 1 , with the difference that the section 13 is here in the maintenance position.
  • the job 1 is accordingly out of service.
  • the locking element 23 has previously been released.
  • the transducer 15 is located for example at section 13, the switching element 16, for example, the static frame of the job 1. It would also be conceivable, the components of the sensor 14 on the other component to arrange.
  • a first channel section 17 of the fiber extraction is arranged on the frame 22.
  • a second channel section 20 is part of the section 13.
  • both channel sections 17, 20 form a unit.
  • the negative pressure which bears against the first channel section 17 can thus be brought into the region of the yarn 7 via the second channel section 20.
  • the components 17, 20 of the fiber extraction and at least one electronic component 21 easily accessible to the operating personnel. This facilitates the maintenance and / or cleaning of the components 17, 20 of the fiber extraction and / or of the at least one electronic component 21.
  • Examples of electronic components 21 are, in particular, electric motors, printed circuit boards, integrated circuits, power supply units and connecting cables.
  • the sensor 14 registers that the section 13 of the workstation 1 is not in the operating position. This information can be made available to the operating personnel, for example via corresponding display means. In addition, for example, the power supply to the workstation 1 is interrupted in this position of the section 13, or an operation of the workstation 1 are automatically prevented. In this way, the sensor 14 lowers the risk to man and machine.
  • FIG. 3 shows a front view of the workstation 1 with the section 13 in the maintenance position. It can be clearly seen that the first channel section 17, as well as the second channel section 20 of the fiber extraction and the electronic components 21 are accessible in this position of the section 13. The possible arrangement of the pickup 15 on section 13 and the switching element 16 on the frame of the workstation 1 can be clearly seen in this view.
