Description

  The present invention is a textile machine including a plurality of working units, and includes a movable unit that is movable along the working unit, and the movable unit and the working unit are provided for cleaning lint and dust of the textile machine. The present invention relates to a textile machine provided with an opening through which intake air or discharge air is supplied.

  During the spinning process and the winding process, a considerable amount of particles such as dust, lint, finish and dirt are generated. These particles float in the air, and some of them are deposited on the surface of the components of the spinning machine and the winder. The occurrence of such dust and dirt depends on the material to be processed and the selected production parameters, such as winding speed or paraffin processing. In addition, the release of this type of particles increases the friction with which the traveling yarn is exposed at several places in the yarn path, for example where there are yarn guides. Furthermore, additional contamination is caused by the operation of adjacent textile machines.

  In the case of a winder, dirt may occur in, for example, a yarn tension adjusting device, a yarn clearer measuring head or a paraffin processing device. These stains may lead to functional problems in a textile machine having a plurality of working parts and quality problems of the tram roll package to be manufactured. For example, if dirt is present between the disks of a disk-type tension adjusting device, the thread tension can no longer be adjusted accurately. Contamination of the clearer measuring head can lead to incorrect calibration of the clearer or incorrect measurement values. As a result, there are cases where the presence of those parts is notified where there are no thick parts, thin parts, or foreign fibers, or such defects are not recognized. Dirty paraffin processing equipment can adversely affect waxing.

  In order to alleviate this kind of functional problem or quality problem, it is known to use various units used for cleaning in textile machines with a plurality of working parts.

  These cleaning units can be roughly classified into two groups. One is an apparatus that exists in each working unit of a textile machine including a plurality of working units, and the other is a movable unit that is movable along the plurality of working units. The movable unit varies in function in part, depending on what kind of textile machine it is used for. However, all the movable units are common in that they are used for cleaning textile machines with a plurality of working parts.

  The movable unit patrols along the working part of the textile machine having a plurality of working parts permanently or at intervals, and sucks impurities like a vacuum cleaner, and at the same time, the textile machine having a plurality of working parts Blow and clean a specific working part. The sucked dust is collected in a special chamber of the movable unit, and is discharged to a suction device of a textile machine having a plurality of working units for each cleaning cycle.

  In parallel with this, there is dust removal in which dust is sucked directly at the generation point during the feeding process. The suction performance of the suction part arranged in the immediate vicinity of the yarn feeding bobbin can be adjusted via an adjustable rotational speed control.

  Further, the air is blown through a specially arranged blower nozzle, aiming at a device that is particularly sensitive to dirt in the working part, and cleaning is performed. This is done via a separate pressure device connected to each working part. The strength of the cleaning by the blow nozzle can be controlled by the number and length of blow pulses.

  The following Patent Document 1 discloses a movable cleaner that can move on a moving rail disposed in a longitudinal direction with respect to the winder above the winder. On the one hand, the movable cleaner sends air to the winder via the blower tube and the blower nozzle, and on the other hand, sucked up dust is sucked by suction tubes entrained on the long sides on both sides of the textile machine.

  Further, Patent Document 1 describes that an air inlet is disposed above the yarn feeding bobbin. The air inlet is formed so that an air flow is generated along the yarn supplying bobbin. Dust generated when the yarn is unwound is sucked into the air inlet as the air flows.

  In Patent Document 2 below, it is known to arrange one or a plurality of suction openings on the side of a yarn feeding bobbin. In addition, it is advantageous if a special blast nozzle is directed to the machine part in contact with the yarn.

  An example of this special blowing nozzle is described in Patent Document 3 below, for example. A blower nozzle device is installed in the bottom region of the stationary housing of the paraffin processing apparatus. The blower nozzle device is connected to a positive pressure source and can be controlled as specified by a valve. The valve is controlled by the working unit computer.

  There are similar moving units for spinning machines. The movable unit for the spinning machine performs cleaning permanently or periodically.

  As for the open-end rotor type spinning machine, for example, a cleaning device for an open-end spinning unit is known from Japanese Patent Application Laid-Open No. 2004-228561. This cleaning device is arranged on a movable movable unit and has a mechanical cleaning tool and / or a blower nozzle.

  As described in Patent Document 4, the mechanical cleaning tool can be swung in the fiber assembly groove of the spinning rotor. Furthermore, in order to assist mechanical cleaning, additional discharge air can be blown into the spinning rotor through the nozzle. Furthermore, a cover capable of additionally supplying negative pressure can be positioned with a small space in front of the spinning rotor. The foreign particles separated through the cover are sucked out.

  Patent Document 5 listed below discloses a movable cleaner for a ring spinning machine. This type of movable cleaner includes a movable frame having two lateral legs, i.e. movable legs arranged on the long sides of the ring spinning machine. The leg is provided with a line for introducing the blown air and leading out the exhaust with the fibers.

  However, the method and apparatus for cleaning a textile machine having a plurality of working parts, which have been described above as a background art, generally have the disadvantage that the cleaning parameters must be manually input to the control device. If optimal cleaning parameters are not selected, this can lead to increased fouling and resulting malfunctions, even quality problems, or wasted energy due to excessive cleaning. is there. The parameters to be entered are, for example, the time interval of the repetition, the height of the suction or discharge air output or the number of cleaning blow pulses during one cleaning cycle.

  Despite automated cleaning and known optimization strategies, situations may arise where cleaning is not optimally performed due to manually selected inputs.

German Patent Application No. 4131525 German Patent Application No. 2919768 German Patent Application No. 102005028751 German Patent No. 2629161 Swiss patent No. 686191

  The object of the present invention is therefore to propose a textile machine comprising a plurality of working parts in which improved cleaning of the working parts is realized.

  The above problem is solved by the features described in the characterizing portion of claim 1 of the present invention.

  Preferred embodiments of the present invention are the inventions according to the dependent claims.

  In order to solve the above-described problem, the textile machine according to claim 1 includes a device that detects dirt on the working unit with a sensor and transmits a detection result to the control device. The supply of intake air or discharge air is adjusted to be controlled as necessary.

  The advantage of a textile machine with a plurality of working parts monitored by sensors is that the cleaning unit can be used appropriately based on objective criteria. For this purpose, one or a plurality of sensors are arranged at a location where the contamination of the textile machine including a plurality of working units is a problem, and the state of each contamination is monitored. When dirt is detected by one of the sensors, the detection result is transmitted to the control device. Therefore, the control device serves to supply suction air or discharge air to the opening provided in each movable unit or the corresponding working unit. Manual input by the operator to the controller is omitted, and cleaning is not affected by the subjective feeling of the operator according to the present invention.

  Thus, a textile machine with a plurality of working parts is always best cleaned without fear of failure due to cleaning that is not optimally performed or excessive cleaning.

  Preferably, as described in claim 2, the openings are connected to a common discharge air or suction air line, which is supplied with suction air or discharge air at the center, respectively.

  As a result, it is possible to supply each opening according to need, so that the cleaning process is flexible. For example, discharge air can be supplied to a certain opening first, and a certain range of lint and dirt are blown away. Thereafter, suction air can be supplied subsequently, and lint and dirt wound up earlier can be sucked. Thereby, it is possible to prevent the wound lint and dirt from accumulating again on the textile machine including a plurality of working units.

  In particular, the connection between the openings and the respective discharge air or suction air lines can be switched individually or in groups based on the control signal of the control device.

  Depending on the contamination that occurs, it may be meaningful to clean individual working parts or to clean a larger working area, for example a section. Importantly, the cleaning is objectively controlled in accordance with the present invention in accordance with the dirt generated.

  As described in claim 4, the control device is adjusted to control the movement of the movable unit as required.

  The movable unit is, for example, a “movable cleaner” used in winders or ring spinning machines, or in a “Wenchseler reininger wagener” generally used in, for example, open-end rotor spinning machines. Depending on the situation, the corresponding cleaning method must be controlled as required by the controller to obtain the advantages of the present invention.

  According to a fifth aspect of the present invention, the device for detecting dirt by a sensor is a reflective photoelectric sensor (Reflexion slitchrank).

  The photoelectric sensor can in principle record the change caused by the object in the intensity of the light and convert it into an electrical signal suitable for subsequent processing.

  In a preferred embodiment, a reflective photoelectric sensor is used. The advantage of the reflective photoelectric sensor is that the feeder line at the second location can be saved. This is because the light projecting unit and the light receiving unit are disposed adjacent to each other in space, but are optically separately incorporated in one housing. The light projecting portion of the reflective photoelectric sensor is directed toward the reflective unit that is just facing, and projects light. The light is only reflected by the reflection unit and returned toward the light receiving unit.

  In principle, other sensors capable of detecting dirt are also within the scope of the present invention.

  Preferably, as defined in claim 6, the opening is arranged in the vicinity of a device sensitive to dirt on the working part or a device for discharging dirt.

  Such a construction guarantees that malfunctions are avoided, in particular in dirt-sensitive devices, such as the measuring head of a thread clearer. To simplify the cleaning process, it is possible to place an opening directly at this point. As a result, in a device sensitive to dirt, it can be cleaned appropriately in a short time without using a movable unit.

  It is also meaningful to place such openings in the area of the device that causes contamination. As a result, even in devices that cause dirt, lint and dirt can be sucked before they diffuse and accumulate on a textile machine with a plurality of working parts.

  Furthermore, it is advantageous if the opening is arranged in the vicinity of the yarn feeding bobbin.

  As already explained, it is advantageous if lint and dirt are already sucked at the site of occurrence. In this way, it is avoided that impurities are diffused into the spinning mill and deposited on a textile machine comprising a plurality of working parts.

  Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings.

It is a figure which shows one working part which has a sensor and opening of a textile machine provided with a some working part.

  FIG. 1 is a schematic side view of a textile machine including a plurality of working units, that is, one working unit 2 of a “winder” 1 in the present embodiment.

  Such a winder 1 is provided with a plurality of working units 2 of the same kind arranged adjacent to each other in a row. In the working unit 2, as is well known, therefore, a detailed description will not be given. However, the yarn feeding bobbin 3 around which a relatively small volume of yarn is wound is wound back on the large capacity winding package 5.

  In addition, during the rewinding, the running yarn 16 is monitored for possible yarn defects which may possibly be present and possibly removed, as is known. For this purpose, the so-called clearer has a measuring head device 20 and a cutting device 22.

  Furthermore, the yarn 16 is paraffinized during the rewinding process. That is, the yarn 16 is guided through the paraffin processing device 19. The paraffin processing device 19 reduces the friction coefficient of the yarn 16. That is, the running characteristics and sliding characteristics of the yarn 16 are greatly improved by such paraffining.

  After completion, the tram roll package 5 is delivered to a tram roll package transport device 7 that extends over the entire length of the machine by a service unit (not shown) that automatically operates, and the package load station disposed on the machine end side or this It is transported to a similar station.

  As further schematically shown in FIG. 1, such winders 1 are often equipped with a bobbin and tube transfer system 6. In the bobbin / pipe conveyance system 6, the yarn feeding bobbin 3 or the empty pipe is circulated on the conveyance tray 11. Of such a bobbin / tube conveyance system 6, FIG. 1 shows only a cup supply section 24, a reversible drive storage section 25, a lateral conveyance section 26 leading to the winding unit 2, and a pipe return section 27. .

  Furthermore, each working unit 2 has various devices that guarantee the normal operation of this type of working unit. Such devices are known per se and are therefore only schematically shown in FIG.

  One of these known devices is, for example, a winding device 4. The winding device 4 has a package frame 8 that is movably supported around the turning axis 12. In the present embodiment, the surface of the traverse winding package 5 is placed on the driving drum 9 during the winding process, and is rotated by the driving drum 9 based on frictional coupling (Reibschss).

  A yarn traversing device 10 is provided for traversing the yarn 16 during the winding process. Such a known yarn traverse device 10 shown only schematically in FIG. 1 has, for example, a yarn guide 13 having a yarn displacement lever formed in a finger shape.

  Furthermore, the splicer device 18 and the yarn tension adjusting device 17 are shown schematically. The yarn tension adjusting device 17 is formed as a disk-type tension adjusting device in the illustrated embodiment. The yarn tension adjusting device 17 provides a necessary yarn tension during normal winding operation, and grips the lower yarn when the yarn is broken.

  Reference numeral 40 indicates a blower specific to the working unit. The individual openings 41, 42, 43, 44, 45 can be connected to a combined discharge / suction air source 37 by a solenoid valve 38. The solenoid valve 38 is controlled by the control device 28 unique to the working unit. The blower 40 has a total of five openings 41, 42, 43, 44, 45. The first opening 41 is directed to the paraffin processing device 19, the second opening 42 is directed to the clearer measuring head 20, its measuring slit and the cutting device 22, and the third opening 43 is directed to the yarn tension adjusting device 17. Is directed to. The fourth opening 44 and the fifth opening 45 are provided in the region of the yarn feeding bobbin 3.

  Further, one reflective photoelectric sensor 46 is disposed in the vicinity of the paraffin processing device 19, the clearer measuring head 20, the yarn tension adjusting device 17, and the yarn feeding bobbin 3.

  Further, the winding unit 2 has an operation unit 30. The operation unit 30 is connected to the control device 28 via a communication line (not shown). Further, the control device 28 controls and monitors the above-described various devices of the winding unit 2 via a line (not shown). The operation unit 30 can display to the operator the state of the winding unit 2, for example, that a cleaning operation is being performed, and has a signal lamp 31 for this purpose.

  According to the present invention, the reflective photoelectric sensor 46 detects each predetermined range. When it is detected that the yarn tension adjusting device 17 is increased in dirt, a corresponding signal is transmitted to the control device 28. Next, the control device 28 supplies discharge air to the opening 43. As a result, the attached lint and dirt are blown off from the yarn tension adjusting device 17. Subsequently, suction air is supplied to the opening 43, and lint and dirt wound up immediately before are sucked.

  When all the reflection type photoelectric sensors 46 detect unacceptable dirt, in addition to the control of the openings 41, 42, 43, 44, and 45 unique to the working unit, the photoelectric sensor 46 also has an opening through which suction air or discharge air is supplied. In the case of a corresponding movable unit or winder, a movable cleaner (not shown) is controlled.
