MACHINE COMPOSITE RING SPINNING MACHINE / CROSS WINDER

Description

[0001] The invention relates to a device for operating a machine combination comprising a ring spinning machine and a cross-winding machine, wherein a first part of a tube and spinning cop transport system is arranged in the area of ​​the ring spinning machine and a second part of the tube and spinning cop transport system is arranged in the area of ​​the cross-winding machine and a device is provided which monitors the completeness of the peg trays carrying fresh spinning cops or empty tubes and which circulate in the tube and spinning cop transport system.

[0002] On ring spinning machines, which usually have a large number of similar spinning stations, spinning cops are produced which, as is well known, have a relatively small amount of yarn and are therefore wound into large-volume cross-wound bobbins on textile machines downstream in the production process, preferably on the winding stations of automatic cross-winders.

[0003] During the production of spinning bobbins, the problem can occasionally arise that individual spinning stations on the ring spinning machine operate incorrectly without the operator noticing. This means that since the yarns are always finished on the numerous spinning stations of a ring spinning machine during the production of spinning bobbins immediately before they are wound onto the spinning bobbins, direct quality control of the yarns and thus of the spinning bobbins is virtually impossible at the spinning stations of such ring spinning machines.

[0004] During the production of spinning cops, usually only the thread breaks that occurred at the individual spinning stations of the ring spinning machine during the production of the spinning cops are counted.

[0005] In most cases, there is no information available regarding the cause of thread breakage, for example inadequate feed material or a faulty spinning spindle.

[0006] As already indicated above, with such ring spinning machines, there is always the risk that a spinning unit, despite having, for example, a faulty spinning spindle, will continue to produce inferior bobbins for an extended period of time without the operating personnel noticing. This is particularly the case if the faulty spinning unit is not noticeable due to an excessive number of thread breaks.

[0007] In practice, such inferior spinning cops are usually only discovered when they are later rewound on a winding station of a downstream automatic cross-winder, i.e. when the thread unwound from the spinning cop is scanned by sensors before being wound onto a cross-wound bobbin and, for example, is checked for its yarn quality.

[0008] For this purpose, the well-known automatic cross-winding machines have various handling and sensor devices in the area of ​​their winding stations, by means of which the thread drawn off the spinning cop during the rewinding process is continuously processed and monitored.

[0009] The winding units of automatic cross-winding machines, for example, have a so-called thread cleaner, which monitors the running thread for thread defects such as thick spots, thin spots or double threads and ensures that such serious thread defects are cut out immediately.

[0010] Although the use of such thread cleaners can prevent defective thread material from being rewound onto a cross-wound bobbin, without further measures it is not possible to determine at which of the spinning stations of an upstream ring spinning machine the defective spinning cop was produced.

[0011] In order to identify such faulty spinning positions of ring spinning machines, numerous, sometimes quite different, methods and devices have been developed in the past.

[0012] DE 37 12 654 A1, for example, describes a method in which the spinning cops produced on the spinning stations of a ring spinning machine are transferred from a ring spinning machine to a cross-winding machine in a sequence related to their spinning station position.

[0013] The bobbins are first fed to a measuring, counting, and sorting device located between the ring spinning machine and the automatic cross-winder. In the measuring, counting, and sorting device, the bobbins are sensorily checked for various quality criteria and, if necessary, sorted out. The spinning station that produced the bobbin in question is also determined.

[0014] However, the use of such measuring, counting, and sorting devices is not only relatively space-consuming, but also relatively costly. Therefore, such measuring, counting, and sorting devices have not been able to gain widespread acceptance in practice.

[0015] DE 36 03 002 A1 discloses a device in which the peg trays for the spinning cops each have a special identification marking. The spinning cops completed at the spinning stations of the ring spinning machine are each positioned on one of these marked peg trays in such a way that it is later possible to identify which of the spinning stations of the ring spinning machine produced the respective spinning cop.

[0016] Furthermore, devices are known, for example from DE 40 02 500 A1 or DE 42 09 203 A1, in which the peg trays are each equipped with a marking element designed as an erasable and writable memory chip. The memory chip records which of the spinning stations of a ring spinning machine produced the respective spinning cop. This means that if it is determined at a winding station of the automatic cross-winder, for example by means of a thread clearer, that a spinning cop does not contain the correct yarn material, it is relatively easy to determine which of the spinning stations of a ring spinning machine upstream in the production process produced the defective spinning cop.

[0017] DE3902181A1 describes a management method for spinning machines in which an identifier is applied to each bobbin plate for transporting the spinning bobbins produced by a spinning unit to the winding units of a winding device. When the bobbins are transferred from the spinning unit to the bobbin plate, the identifier is read, and the spinning unit from which the respective bobbin originates is stored. When the thread is rewound from the bobbin, thread defects are detected; the identifier applied to the bobbin plate of the respective bobbin is read, and the stored information is analyzed for spinning unit errors.

[0018] However, in connection with the production of spinning bobbins on the spinning stations of ring spinning machines, difficulties often arise during the transport of peg trays within the ring spinning machine area. This means that it occasionally happens that one or more peg trays are removed from the transport and drive belt of the tube and bobbin transport system or fall out unnoticed.

[0019] Such a loss of peg trays not only has a very negative effect during the doffing process of the ring spinning machine, since in the area where no peg trays are positioned in front of the spinning stations, the fresh spinning cops simply fall to the ground and are then often unusable, but missing peg trays also often make it difficult or even impossible to identify faulty spinning stations later on.

[0020] To prevent the absence of some peg trays from going unnoticed for an extended period in a machine system where the ring spinning machine, for example, has 1200 spinning positions and the tube and bobbin transport system should accordingly contain exactly 1200 peg trays, which, as indicated, makes it significantly more difficult or even falsifies the identification of malfunctioning spinning positions, it is also known to count the peg trays loaded with spinning bobbins delivered by the ring spinning machine after each take-off of a ring spinning machine and to compare the count result with the number of spinning positions on the ring spinning machine. If it turns out that the number of peg trays circulating in the machine system does not correspond to the number of spinning positions on the ring spinning machine, the take-off data is deleted due to inconsistency.

[0021] A disadvantage of this method, however, is that if a peg tray falls out or is removed from the transport and drive belt of the tube and bobbin transport system of the ring spinning machine, the entire take-up is discarded. This means that the known method cannot identify malfunctioning ring spinning machine spinning stations if a peg tray is missing.

[0022] Based on the prior art described above, the object of the invention is to develop a device which prevents an empty pocket in the transport and drive belt of the tube and bobbin transport system of the ring spinning machine from causing the entire take-off to be rejected.

[0023] This object is achieved according to the invention by a device which is characterized in that a writing device is provided in an area between the second part and the first part of the tube and spinning cop transport system, which writing device ensures continuous identification of the peg trays loaded with empty tubes running into the first part from the second part of the tube and spinning cop transport system, and in that a reading and writing station is installed in the area between the first part and the second part of the tube and spinning cop transport system, which reading and writing station records the identification of the peg trays loaded with fresh spinning cops running out of the first part of the tube and spinning cop transport system and which, if it determines that at least one peg tray is missing due to non-continuous identification of the peg trays, immediately initiates a correction of the current spinning station number of the ring spinning machine.

[0024] Advantageous embodiments of a method for operating the device described above are the subject of the subclaims.

[0025] The device according to the invention has the particular advantage that the reading and writing station immediately detects the absence of a peg tray and immediately corrects a gap in the drive and conveyor belt of the tube and bobbin transport system of the ring spinning machine in such a way that a correct assignment of the peg trays to the spinning station numbers is still possible.

[0026] According to an advantageous method for operating a ring spinning machine / automatic cross-winder machine system, for example, the read / write station immediately interprets a gap in the continuous marking of the peg trays as a loss of at least one peg tray and then immediately ensures that the current spinning position number of the ring spinning machine is corrected. Such a correction thus ensures that the relevant take-off is not discarded during the next counter check, but rather that the spinning position numbers are correctly assigned to the spinning positions of the ring spinning machine.

[0027] In a further advantageous embodiment of the method according to the invention, in which the read and write station evaluates the absence of a number in the otherwise continuous identification of the peg trays equipped with spinning cops leaving the first part of the tube and spinning cop transport system as a loss of a peg tray, the current spinning station number is incremented by 1. This means that if a missing peg tray is detected, the count is corrected from the next spinning cop onwards by adding a 1. If, for example, it is detected that the peg tray with the number 99 is missing, the 1 is added after the gap at the peg tray which is actually the 99th according to the count and the spinning cop is thus correctly assigned to spinning station 100.

[0028] Further details of the invention can be found in an embodiment illustrated below with reference to the drawings.

[0029] It shows: Fig. 1 schematically shows a machine combination of a ring spinning machine producing spinning cops and a downstream automatic cross-winder winding the spinning cops into cross-wound bobbins, which is equipped with the device according to the invention, Fig. 2 in front view two spinning stations of a ring spinning machine during the production of spinning cops, Fig. 3 in side view a winding station of an automatic cross-wound bobbin during the rewinding of a spinning cop onto a cross-wound bobbin with working elements that monitor the thread running onto the cross-wound bobbin.

[0030] The Figure 1 shows schematically, in perspective view, an embodiment of a machine combination ring spinning machine / cross-winding machine in which the device according to the invention or the method according to the invention is used.

[0031] As is known, on the spinning stations 8 of such ring spinning machines 1, which are Figure 2are shown in more detail, spinning cops 13 are manufactured which have relatively little yarn material and which are therefore later wound on the winding stations 16 of a cross-winding machine 2, as in Figure 3 shown, are rewound into large-volume cross-wound bobbins 48. The thread 35 drawn off from the spinning cop 13 is scanned by various handling and sensor devices, whereby the data determined often provide information about the operating state of the spinning station 8 of the ring spinning machine 1 that produced the respective spinning cop 13.

[0032] As in Figure 1As indicated, ring spinning machines 1 generally have, between their end frames A and B, a plurality of identical spinning stations 8 arranged adjacent to one another on both longitudinal sides of the ring spinning machine 1, on which spinning cops 13 are produced. Such ring spinning machines 1 also often have, in the area of ​​their often more than a thousand spinning stations, a first part 3 of a tube and spinning cop transport system 6. In this tube and spinning cop transport system 6, so-called peg trays 14 circulate, each of which is equipped with a writable and erasable memory chip, which enables precise identification of the peg tray 14.

[0033] On the peg trays 14, either fresh spinning cops 13 or empty tubes 5 are usually arranged in a vertical orientation.

[0034] In the present embodiment, the ring spinning machine 1 has a part of the tube and bobbin transport system 6, which is designated by the reference number 3. This part 3 has a drive and conveyor belt 9, which is guided around the numerous spinning stations 8 of the ring spinning machine 1 and is generally upright and which is provided with corresponding pockets arranged between projections for conveying Figure 1 not shown peg trays 14. Part 3 of the tube and spinning cop transport system 6 also has a long transport section, a so-called Cowemat section 10 or 11, in the area of ​​the longitudinal sides of the ring spinning machine 1, wherein the Cowemat sections 10 or 11 are coupled at the machine end via a so-called Cowemat connecting section 12.

[0035] The spinning positions 8 of the ring spinning machine 1, which are Figure 1are only indicated very schematically by some feed bobbins 30, some drafting systems 26 and some spinning spindles 28, will be explained later on the basis of the Fig. 2 explained in more detail.

[0036] In the present embodiment, the spinning cops 13 produced by the spinning stations 8 of the ring spinning machine 1 are transferred, after their completion, by means of a known (not shown) doffing device, preferably by means of a so-called COWEMAT, onto numerically labeled peg trays 14 positioned in front of the spinning stations 8. The peg trays 14 loaded with fresh spinning cops 13 are then conveyed by part 3 of the tube and spinning cop transport system 6 arranged in the area of ​​the ring spinning machine 1 to part 7 of this tube and spinning cop transport system 6 installed in the area of ​​the automatic cross-winder 2.

[0037] At the same time, peg trays 14 loaded with empty tubes 5 are conveyed back from part 7 of the tube and spinning cop transport system 6, i.e. from the automatic cross-winder 2, to part 3 of the tube and spinning cop transport system 6 of the ring spinning machine 1.

[0038] As in Figure 1 As shown, a writing device 4 is installed, for example, in the area of ​​the entrance to part 3 of the tube and spinning cop transport system 6, with which the peg trays 14 loaded with empty tubes 5 entering part 3 of the tube and spinning cop transport system 6 are written with a consecutive number. This means that the writing device 4 labels the incoming peg trays 14, each equipped with a writable and erasable memory chip and loaded with an empty tube 5, with consecutive numbers.

[0039] Using this number, it can later be determined, if necessary, at which of the spinning stations 8 of the ring spinning machine 1 the relevant peg tray 14 was positioned at the time of doffing of the ring spinning machine 1, i.e. the marking of the peg trays 14 enables, if necessary, a reliable assignment of the peg tray 14 and thus of the spinning cop 13 to the spinning station 8 of the ring spinning machine 1 that produced the relevant spinning cop 13.

[0040] Furthermore, for example in the area of ​​the outlet of part 3 of the tube and spinning cop transport system 6, a read and write station 25 is installed, which counts the incoming peg trays 14 equipped with fresh spinning cops 13 and monitors whether the incoming peg trays 14 have consecutive numbers.

[0041] Preferably, both the writing device 4 and the reading and writing station 25 are connected to a central control unit 55 of the machine network, which is installed, for example, in the area of ​​the automatic cross-winder 2.

[0042] Like the ring spinning machine 1, the cross-winding machine 2 is also Figure 1 shown only very schematically. This means that the representation of the automatic winder 2 is essentially limited to the energy and operating unit 15, to position information for the winding units 16 and to part 7 of the tube and spinning cop transport system 6. The exact design of the winding units 16 of the automatic winder 2 and the function of these winding units 16 will be explained later on the basis of the Figure 3 explained in more detail.

[0043] As can be seen, the part 7 of the tube and spinning cop transport system 6 arranged in the area of ​​the automatic cross-winder 2 has various sections on which peg trays 14 circulate and which serve to supply the winding stations 16 of the automatic cross-winder 2 with fresh spinning cops 13 or to dispose of the winding stations 16 of empty tubes 5.

[0044] The peg trays 14 supplied by the ring spinning machine 1 and equipped with fresh spinning cops 13, after passing the reading and writing station 25, first reach, for example, a machine-long cop feed section 18.

[0045] The peg trays 14 are then transported via the bobbin feed section 18 to the area of ​​one or more preparation sections 19, each of which has a bobbin preparation station 20 positioned thereon. Furthermore, the preparation sections 19 are each connected via a removal section 21 to a so-called storage section 22, which alternately switches from left-hand to right-hand rotation. Via the storage section 22, the spinning bobbins 13 arranged on the peg trays 14 reach the inlet area of ​​cross-transport sections 23, which are each arranged below the individual winding units 16 of the automatic cross-winder 2 and have a so-called unwinding position. The cross-transport sections 23 are also connected at their ends to a tube return section 24, via which the peg trays 14 loaded with unwound empty tubes 5 are returned to the ring spinning machine 1.

[0046] In Figure 21 is a schematic representation of a section of a longitudinal side of a ring spinning machine 1 with two adjacent spinning stations 8. As can be seen, each of the spinning stations 8 has a plug-in unit 26 and a drivable spinning spindle 28 mounted for rotation about a spindle axis 27, on the spindle shaft of which the yarn tube of a spinning cop 13 can be secured. During spinning, a roving 31 originating from a feed bobbin 30, for example a flyer bobbin arranged above the drafting unit 26, is drawn in the drafting unit 26 to a desired yarn thickness. The drawn fiber strand is delivered to a yarn tube arranged on a rotating spinning spindle 28, and the fiber strand is given a twist in the process. The resulting thread 35 is then wound onto the yarn tube to form a spinning cop 13.As is usual with ring spinning machines, the thread 35 is guided between the drafting system 26 and the spinning cop 13 by a thread guide 36, a balloon constriction ring 37 and a rotating ring traveler 39 which is rotatably mounted on a spinning ring 38 and dragged along by the thread 35 during spinning operation.

[0047] As can be seen, the drivable spinning spindles 28 of the spinning stations 8 are each fixed with their spindle housing 40 to a spindle bank 41 which extends in the longitudinal direction of the ring spinning machine 1 and which in turn is fixed in a stationary manner to a machine frame of the ring spinning machine 1.

[0048] The spinning spindles 28 are either equipped with an individual drive or, as in the exemplary embodiment, are acted upon and rotated during spinning by a machine-length, circulating, driven tangential belt 44.

[0049] The spinning rings 38, on which the ring travelers 39 rotate, are, as usual, each installed by means of a bearing arrangement in a ring bank 45, which, like the bank 46 for the above-mentioned balloon constriction rings 37 or the bank 47 for the thread guides 36, is vertically displaceable during spinning operation, as indicated by arrows. Figure 3 shows a schematic side view of a winding station 16 of a cross-winding machine 2. On such winding stations 16, the spinning cops 13 produced on the spinning stations 8 of a ring spinning machine 1 upstream in the production process, which have relatively little yarn, are rewound into large-volume cross-wound bobbins 48, which, after their completion, are transferred by means of a service unit (not shown) to the machine-length cross-wound bobbin transport device 17 and transported to a bobbin loading station or the like arranged at the end of the machine.

[0050] To supply the winding stations 16 with fresh spinning cops 13 or to dispose of the winding stations 16 of unwound empty tubes 5, such automatic cross-winders 2, as already explained above, have a second part 7 of a tube and spinning cop transport system 6, in which spinning cops 13 and empty tubes 5 circulate on peg trays 14. Of this tube and spinning cop transport system 6, Figure 3 only the cop feed section 18, the reversibly driven storage section 22, one of the cross transport sections 23 leading to the winding stations 16, each equipped with an unwinding position AS, and the tube return section 24 are shown.

[0051] The winding units 16 of such automatic cross-winding machines 2 are also equipped with various handling and sensor devices which enable proper operation of the winding units 16 during the rewinding process of the spinning cops 13.

[0052] One of these handling devices is, for example, the winding device designated by the reference number 29, which has a bobbin frame 33 mounted so as to be movable about a pivot axis 32.

[0053] As shown, the cross-wound bobbin 48 rests with its surface on a bobbin drive roller 34 during the regular winding process and is driven by it via frictional engagement. The bobbin drive roller 34 is connected, for example, to an individual electric motor drive, which is connected to a winding station computer 42 via a control line. To traverse the thread 35 wound onto the cross-wound bobbin 48 during the winding process, a thread transfer device 43 is provided, which continuously traverses the thread 35 between the two end faces of the cross-wound bobbin 48.

[0054] Each of the winding units 16 also has a suction nozzle 49 which can be subjected to negative pressure and is pivotably mounted for handling the so-called upper thread, a gripper tube 50 which can also be subjected to negative pressure and is pivotably mounted for handling the lower thread, and a pneumatic thread splicing device 51 by means of which, if necessary, for example after a thread break, the thread ends of the upper and lower threads can be reconnected, almost identically.

[0055] Such winding units 16 are also often equipped with additional devices, such as a bobbin thread sensor 52, a thread tensioner 53, an electronic thread cleaner 54, a thread cutter 56, a waxing device 57, and a thread tension sensor 58. These devices are also generally connected to the winding unit computer 42 via control and signal lines.

[0056] As is known, during the rewinding process, the electronic thread cleaner 54 continuously monitors the quality of the running thread 35. This means that the thread cleaner 54 continuously checks the thread 35 passing through it and detects serious thread defects, such as thread breaks, double threads, or thin and thick spots.

[0057] If such thread defects occur frequently in a spinning cop 13, this can be interpreted as an indication of a possibly faulty ring spinning machine spinning position 8.

[0058] The running thread 35 is also often scanned by a thread tension sensor 58 during the rewinding process.

[0059] If, during the rewinding process of a spinning cop 13, there is an unexpected significant increase in thread tension, which is usually due to the spinning cop 13 being wound slightly too tightly, this can also be interpreted as an indication that the spinning station 8 of the ring spinning machine 1 that produced the spinning cop 13 in question is in a faulty operating condition or is about to leave its proper operating condition. This means that a tightly wound spinning cop 13 can, for example, be interpreted as an indication that the ring traveler 39 of the spinning station 8 that produced the spinning cop 13 in question is in a state of wear, which raises concerns that the affected spinning station 8 will continue to produce spinning cops 13 that are too hard and thus unusable in the future, and that it is therefore advantageous to inspect the spinning station 8 and, if necessary, repair it. Function of the device or method according to the invention:

[0060] When starting a new yarn batch, for example, a ring spinning machine 1 must first be supplied with empty tubes 5. This means that in the case of a ring spinning machine 1 with, for example, 1200 spinning positions, 1200 peg trays 14 equipped with empty tubes 5 are initially fed into the ring spinning machine 1 via the tube and bobbin transport system 6. The peg trays 14 are provided with a consecutive number in the outlet area of ​​the empty tubes 5 in the winding machine 2. When the storage limit is reached, they are numbered consecutively again starting with 1. The range for the consecutive numbers does not have to be limited to the number of spinning positions 8; for example, it can extend over the range 1 - 4095. The number of the peg tray 14 that is located in front of the respective spinning position 8 of the ring spinning machine 1 is not known.

[0061] Before the spinning stations 8 of the ring spinning machine 1 are put into operation, the empty bobbins 5 are transferred to the spinning spindles 28 of the spinning stations 8 in a doffing device, for example, a so-called COWEMAT, and then wound with yarn material. The finished spinning bobbins 13 are loaded, also by the doffing device, in a common doffing process onto their corresponding peg trays 14, each positioned in front of the spinning stations 8.

[0062] The first peg tray 14 after a new doff arriving at the read / write station 25 is assigned the spinning station number 1 and the current doff number. The entered number, for example, from the range 1 - 4095, is also saved. The labeling of the peg trays 14 should be consecutive; for example, peg trays 14 with the numbers 96, 97, 98, and 99 should be followed by a peg tray 14 with the number 100.

[0063] However, if the read and write station 25 determines that, for example, peg tray 14 with the number 98 is followed by a peg tray 14 with the number 100, this is a sure indication for the read and write station 25 that the drive and conveyor belt 9 of the tube and bobbin transport system 6 of the ring spinning machine 1 has a gap. This means that the peg tray 14 with the number 99, which should have been positioned in front of the corresponding spinning station 8 of the ring spinning machine 1 during the doffing process, is missing. The spinning station number of the ring spinning machine 8 is then increased by a factor of 1 before writing, since the peg tray 14 with the number 99 is missing.

[0064] According to the prior art, in such a case, because the missing peg tray 14 posed a risk that a spinning station identification could be incorrect, the entire take-off was rejected during the next counter check of the read and write station 25. To prevent such a rejection of the take-off, the current spinning station number is corrected, i.e., increased by 1.

[0065] After such a correction, during the next counter check, the number of spinning stations 8 of the ring spinning machine 1 again corresponds to the number of peg trays 14 circulating in the tube and bobbin transport system 6, with the result that the take-off is not rejected, but the following spinning station numbers are specifically assigned to the respective spinning stations 8 of the ring spinning machine 1.
