A malfunction, in which the stations are generally shut down until a maintenance inspection requires repairs. carried out by hand, is known as "Valzonumschlingung ¹ '. This occurs when the fed yarn thread gets caught in the feed or feed rollers, is wrapped around an orphan and gets tangled on the roller, even a thread breakage or a Otherwise inadequate thread feed can lead to a roller loop, which also leads or should lead to an indication that a bobbin is not properly wound or that the thread has broken.

A full bobbin is also referred to as a fault in the following, as operation by pulling off the bobbin «' required before it becomes too full. When a bobbin is too much, he rubs on the machine and v? ird then referred to as "black coil", ie © no longer usable is.

In Fig. 1, a multi-spindle spinning machine 11 of the in the aforementioned DT-OSen described type shown, which has a revolving operating runner 12, which runs around a rail 13 and bobbin 14- to IT Spindle stations 15 are operated when they are operated by the rotor 12 be determined · If necessary, the runner will centered and stopped in a precise position indicated by arrow 18 for operation. The rail length, the configuration and number of spindles can vary, and a runner can move from unit to unit over several Moving spinning machines.

The runner can be put into operation by an automatic or manual signal, so that it is from a Position 17 over a predetermined one, through the rail 15 fixed path is moved to an end position 16. At positions 16 and 1? corresponding switches can be used to start the cycle and output signals or control pulses. While of the circulation cycle, the spindles 1, 2 to N are known Sequence expired, so that each spindle can be identified according to its position on the movement path can.

In doing so, the operator pulls out idle bobbins, cuts the thread to be wound up, sets new bobbin. body and connects the thread to them for winding. If a cycle cannot be completed, the runner also actuates a stop switch and leaves it fold down a flag, whereupon it automatically turns over Moves a / programmed subsequent cycle of operating steps, which can be repeated if a first attempt at operation fails.

According to FIG. 2, the rotating operating runner 12 in a data processing and machine control area in its control system which is divided into two sections, equipment and operating function

The control device may generally comprise electronic circuitry, which in practice is shown in FIG instantaneously with regard to the mechanical processes in the machine, i.e. «work without delay, albeit in a certain way In cases also mechanical or electromechanical, ongoing operations can be advantageous o The electronic System enables the generation of control signals for electromechanically operated equipment, such as driver relays, Motors, electromagnetic brakes or solenoids. In addition, alarm devices and lamps can be activated and mechanical, electromechanical, pneumatic or electronic Counters or counter displays are used, depending on how this is in terms of function or position appears necessary. For example, an operating mechanism can be a switch for counting on a common, close conventional electromagnetic totalizers,

Optionally, the counter can be an electronic counter which dynamically totals stores that queried and used in the system at any point in time by electronic impulses or either to a central office or to a control center can be directed. The counters can be preset in the usual way in order to get a preset Count an advertisement or deliver a query or To ensure readout.

In the data section, input signals are provided from a set of detectors which are used in various of the following Conditions generate signals:

1) When the center of the spindle is reached, a ßpinddetektor ¹ K) emits a pulsating signal G, which causes the runner to interrupt its movement at precisely this position if another signal is detected which describes a stop for operational purposes as desirable . This signal G is used as a pass-through and control pulse elsewhere in the system.

2) An Ilaggensenksensor 50 supplies to each one in operation Station a signal D, which lasts as long as the runner stops at the station, and thus a Indicates farmer condition.

3) A roller wrap detector 60 is placed on the to be operated Station fixes a roller loop at every point in time of its formation and provides a permanent state

4) A thread feed detector 70 checks the thread at a specific one Place in the network for winding the bobbins of the spindle station to be operated, which indicates that the thread is correctly fed and taken up. is winding.

5) When a bobbin is full, a detector gives 45 a continuous signal 3? to display this state for the locker 1st ation, at xvelcher the runner 12 stops.

6) A roving detector detects the at the served station Presence of properly positioned roving

or roving tight.

The different input signals are therefore used for different, Operating modes for storage, counting and machine control still to be explained in more detail are determined and processed.

In the operating section, a cycle program part 20 controls the Operating cycle over one or more different operating modes, while the rotor 12 stops at a spindle «Der Cycle starts at 21 and goes through a bobbin stripping function 22, a set-up function 23 for a new one Bobbin and a flag lowering function 24, in which a spindle station put out of operation and the flag pans down · After an operation is completed the runner is set in motion to the next station to be operated. If, however, the operating cycle not carried out successfully and at time 3!

a malfunction is detected at block 25, this enables System a repetition of the · operating cycle via the control unit 26th

In this operating phase, the machine is controlled in various ways, for example by actuation the rotor drive device 27, shutdown of the spinning machine 28 or simply by triggering a visual alarm device 29 which eliminates the need for a no Indicates repairs to be carried out in the event of an emergency.

Further data is collected and recorded in the operating section, while the various operations are in progress. The output signals of the data part consist of different counts of faults. The counts can be for all during a given period of time or one predetermined number of operating cycles or operating cycles occurring malfunctions summed up or optionally for each individual Spindle can be saved. The counts can be made using View counter readings recorded and processed manually or automatically periodically read and displayed or on recording strips or on individual meters, such as they are indicated generally by the block 30, recorded and displayed.

In the described embodiment, the data mainly due to counting ton malfunctions and other operating conditions either directly on the basis of unprocessed, detected signals or stored indirectly on the basis of signals, alone or in conjunction have been prepared or processed with other signals and presented in a modified form. d.Certain preferred signals as specific examples of the general manner of processing various interference signals and combinations thereof that are applicable to a specific type of textile machine, are disclosed. By way of example only, and without limiting the invention, the illustrated embodiment includes a representative combination of signals for storage of data to do the following three tasks: 1 “Preventing damage to the machine; 2. Delivery of production data for operational management for evaluation and planning; and 3 · supply of data which is used for increasing the operating efficiency can.

If the operator runner according to Pig. 1 and 2 - its rail expires and moves from spindle to spindle, will open a line 42 from each spindle a tactile or switching pulse G delivered. As a basis for determining the operating efficiency of the entire system, it may be necessary to count all spindles, which is done using a spindle counter 4-1 is concerned. This count can be used together with the Number of idle spindles and the number to be described Way of an operation requiring .Spindles for

With each rotor revolution, N spindles are scanned, each respective spindle position being identified by a spindle commutator 43. The latter can be a step switch or its electronic equivalent and is switched by one position by each spindle switching pulse G and by the start or end pulses at positions 16 and 17 according to Pig. 1 synchronized. The respective rotor position can, if desired via the commutator 43 in one central switchboard _t so that the operation state of the plant can be continuously or periodically monitored. The commutator can, for example, have position indicators that light up and supply position information on lines 1, 2, 3 «... Ü, which are used to transmit the counts in each row 31 to 37 of a matrix of separate spindle data counters.

Accordingly, forms in the exemplary .Zählorreihe the pulse taken from a line 52 and sent to the spindle G Plaggensenk signal switched through to a ÜJüD circuit 53 on line 54 a count for registration of an entire plaggeness totaling count in Counter 51 and a flag down count per spindle in each individual spindle counter section 31a, 31b, etc. of the counter row 31, as indicated by the spindle commutator 4-3 were switched through and distributed.

In a similar way, the other faults, such as roll wraps, lack of roving, thread feed and full bobbin, are registered in the relevant counters 51 »51 ' _t 61, 71, 46 and 31 to 37 for totalizing counting and counting per spindle. All of these storage data enable an

If namely on a certain one Spindle an abnormally large number of roll wraps occurs, this indicates the need for repair or maintenance work etc. on this station. The accumulated total counts can indicate that the operator was not able to promptly correct all malfunctions, so that the machine did not perform adequately Efficiency worked. ■ -

If the meters are simple devices with a visual display of the registered Counts are, periodic readings can be taken and every hour or at other time intervals entered so that the disturbances per hour let represent. If the cumulative total counts are not important, the counters can use any Hour, whereby the reading contains an error rate. Similar readings can be made for each operating sequence of the runner or for a certain number of service runs conventional, solenoid operated electromagnetic counters can be used which print a strip when necessary. The system can thus be further automated for data processing by a periodic signal 81 from a clock 80 for reading and, if desired, for Resetting the counters is supplied either in the data or in the operating section, as is done by the outgoing from block 84 Lines 83 is indicated. Similarly, the signal on line 86 could be an indication for each * i 3c service run, or the counter could e.g. a predetermined number of ten or a hundred runs

be removed, as indicated at block 84

Further data will be provided in the manner to be described recorded, counted and stored in the operating section.

The different input signals are controlled by corresponding Detectors supplied, which for example can have the form shown in FIGS. 3 to 7. Depending on the The detectors can position-dependent system speeds and the tolerances with regard to the signals to be recorded Switches, such as microswitches or electromagnetic operated reed switches, or electronic detectors, such as the photoelectric gate directions shown

4 shows a photoelectric spindle detector 40 with a lamp 43 and a lens 46 which focuses a light beam onto a point 49 at which the rounded tip of the spindle 15 reflects a signal onto a photodetector 48 via a lens 47 or an equivalent slit diaphragm . This or equivalent "devices may for precise localization of the exact center of the spindle are generated at which the touch or gating signals G 151, are used, even if the rotor without stopping operations · moved In Fig. 4, a full bobbin detection is also shown as a lamp 33 , which emits a light beam 59 via a lens 56, which is detected by a photodetector 58 via a lens 57 When the winding body 14 of the coil is fully wound, as indicated by the dashed lines 14A, the light beam 59 is interrupted so that - a signal indicating a full coil is generated.

When a flag is lowered by the position of a

-17-309826 / 0925

Flag lever 62 is indicated, which is shown in Fig. ' 5 "at 62A is shown in dashed lines, a light beam 64 passes from a lamp 63 via a lens 65 via a lens 66 to a photodetector 67 and generates a flag lowering signal when the runner arrives at each station and there stops so that the light beam 64 is directed to the flag position 62A.

If, according to FIG. 6, under the influence of the rollers or balls 72 and 73 through the yarn thread 69 on the roller 73, a roller loop 68 is produced, then a light beam 74 directed from a lamp 75 to a photodetector 76, which otherwise only grazes the roller 73 , so reflected that it provides a signal for a roller wrap. This light beam 74 may, if desired, the roll to be directed 73 axially along * In a similar manner (as shown in FIG _{3: 0)} the yarn supply be detected by the presence of a yarn thread 69 in a light beam 79, for example, is directed so that it hits the yarn thread if this runs properly through a mechanism 78 »which can be a spinning device and runs properly from a yarn supply 77 to the bobbin 14 sitting on the spindle 15.

Referring to Fig. 7, a roving or roving detector 44 measures the width, i.e., the diameter of a roving package by . It receives the light reflected from the roving 69. If the Supply roll 77 'is empty, the jet is through the roving not reflected to detector 44. This will make that Presence of roving indicated. If desired, a roving shortage signal can be stored in the form of data

and to change the rotor cycle e.g. by stopping, of the "station in question can be used by folding down the signal flag and indicating to the operator that a Loading with roving is required.

The appropriate input signals to determine the various Fault conditions can therefore be determined by arrangement the detector equipment in the rotor or on the spinning machine are generated to the desired, occurring movements to monitor.

According to Pig. 1 and 2, the machine controller output signals 1.) consist of signals in the brake drive unit 27 for Starting and stopping the rotor 12; 2.) from signals in the control block 28 for shutting down the spinning machine 11 and 3.) from corresponding, possibly desired alarm or control signals, as indicated by block 29

If the controls are set to control every single run, the end signal can trigger a flip-flop 91 to end a cycle, while a start signal activates a switch 92 to reset the flip-flop 91 and let the runner start up for another cycle. The number of revolutions can be counted in a counter 85 on the basis of the revolving pulse signals T which are generated when flip-flops 91 are reset. This start pulse T then actuates a solenoid in the rotor drive unit 27 * to set the rotor in motion until it reaches a station requiring operation or the end of the cycle as specified by an OR gate 9 ^ which actuates a holding solenoid , which has an electromagnetic brake (not shown) in the braking and drive unit

309826/0925

unit 27 of the runner controls.

The runner "is stopped for operation at each spindle station, the one full coil signal F, ein'Waizenumschlingungssignal R or a signal S for disturbed thread feed emits, as shown at the OR circuit 95. This "Operation required ^ / 'signal is then activated by the spindle position switch-through signal G is switched through to an AND gate 96, provided no blocking signals are present. if the runner by a stop signal pulse 97 on the line 98 is stopped, a cycle clock 99 is operated set. If the cycle is not within a - predetermined ' Time is completed by a reset pulse on a line 100, the spinning machine can be on the end of the time signal to the OR gate 101 can be turned off. A wrapper '102 timer is working up in a similar manner due to the start and end signals 16 and 17 (Pig. 1) delivered during a rotor revolution.

When the runner stops, a stop or halt signal passes 97 enter the service cycle program at block 21.

If either a Toll coil ensignal F or a signal S for disturbed thread feed occurs at an operator workstation, as is shown at the OR gate I03 the operator programmed for its sub-work cycle, to cut the thread, and pull off the bobbin at 22. If this sequence of work how through a signal on a line 104 is indicated, ended, a new bobbin is put on by the unit 23 and connected to it for winding the yarn thread.

In general, a multi-spindle is through

309 828/09 2 p. ■ "."

a rotating rotor operated machine set so that that it wraps practically all bobbins evenly and fully, so that all Voilepulen are withdrawn with each rotor revolution and all necessary operation stoppages are performed in the time specified by the turn-around timer 102 · However, if it happens that too many bobbins are served in one cycle, for example seven bobbins or more, it might be a result of holding operations required to correct a condition If the thread feed is interrupted, it is possible that no more bobbins can be pulled off before they are over-wound and rub against the machine and thus become unusable "black coils".

As a result, it is more important to remove the full bobbins than to continue with the other operations. the end For this reason, a counter 105 is provided, which is reset with each rotor revolution by the end pulse · If a number of operating cycles set to seven cycles, for example, is achieved during one revolution, is here the thread feed detector through gate 105 'for the The rest of the revolution is blocked, so that the rotor returns to take up a new revolution without the thread feed detector 70 to be observed. If at any spindle station a flag lowering signal D is present, the blocking signal at gate 96 also allows the runner to continue its movement, without stopping at this station.

A counter 106 can be provided which indicates how often the operating mode occurs with seven steps, and to this Information about the work efficiency and a possible need for maintenance or repair the machine delivers to again a handy

To achieve a uniform output of full bobbins.

Certain combinations of signals are used to indicate malfunctions. For example, the occurrence of the thread feed signal (absence of the signal S) at a station should not coincide with the presence of the flag lowering detection signal D. This represents a fault which ^{can be stored in data 1} form or used to provide an immediate fault indication.

A count of the withdrawn bobbins provides operating information and at the same time provides an indication of the operating efficiency. For this reason, counters 108 and 109 are provided which register full bobbins or partially full bobbins. When the withdrawal process, as indicated by the pulse on the line 1'04, has ended, a full coil is withdrawn when the signal - B ¹ is applied to the AND gate 110; if, on the other hand, a signal S is applied to the AND gate 111, this indicates that the bobbin has been withdrawn and partially full, unless it is blocked by a signal F. . ... '

The operator runner 12 can by lowering the plague 24 shut down every station that cannot be operated. One such condition is the presence of a Wrapping of the rolls, which is normally fixed by hand. The signal R at the OR gate 112 is therefore used to fold down the flag at every station where this is the murmur In addition, by a signal on a line 113 the Flag folded down when the server runner is still closed is not able to successfully end an operating cycle in an explanatory manner *

According to the operating cycle program parts 25 and 26 becomes the program for initiating an operating repeat cycle set up by a signal pulse on line 114. The logic circuits of the depicted Embodiments provide a first and a second attempt at operation and register the number on each of the "relevant counters 115 and 116 for evaluating the operating performance and the machine efficiency. For example, a large number of second attempts may indicate that the Spinning machine requires maintenance, so that a predetermined count on a line 117 an alarm signal on a display block 29 can produce. An excessive number of two attempts can also be made, for example, in section 118 for stopping the Machine because it indicates the possibility of damage or such poor efficiency that it is cheaper to turn off the machine.

The circulation mode becomes at the program time T in the AND gate 119 initiated after the end of an operating cycle if the signal S for disturbed thread feed continues is applied to the OR gate 120. When a reel wrap signal R occurs and there is no flag lowering signal D, shows this state detected by AND gate 121 also indicates the need to repeat the operating cycle. As a result, a pulse NG is provided on line 122 when a repeat cycle is indicated.

The number of operation retry cycles must necessarily be limited, which is why in the illustrated embodiment a counter 123 the number of repeated cycles supervised; the counter is reset by a successful cycle indicated by the clock pulse T on line 124-via the inhibit gate 125 is displayed, i.e. when the

-23- 309826/0925

Signal NG does not exist. In addition, the payer works cyclically so that it automatically resets after a count of two.

The first attempts at operation in the repetition cycle 1 -on a line 125 are used to switch the program at 26 when the program unit "at 25 indicates that the previous operating cycle has been fully carried out and the program unit 20 is ready for the downshift. An OR gate 126 also enables a second iteration of the service cycle on a second attempt count of 2 on the. Line 127.
