Definitions

  • the invention relates to a Fa to-yarn feeder group for mounting on a textile machine, in particular a Ringel-knitting machine, with electrically controllable switch - are or actuating elements in each feeder, which via a common to all trunk groups having a central control device in a signal-transmitting circuit connection.
  • the line bundle is designed as a flat multi-conductor cable, in which at least as many conductors or wires are arranged next to one another as suppliers in the supplier group. For example, since fourteen or more feeders are assigned to a knitting machine, and since several leads or wires may be required in the wire bundle for each feeder, the wire bundle is given considerable dimensions and is difficult to accommodate due to the extremely restricted space.
  • the functionally appropriate connection and "marking" of the suppliers is also extremely complex before the first start-up of the textile machine or after changes or the connection or "marking" of one or more replaced suppliers.
  • the invention is based on the technical problem of forming a Fa en supplier group of the type mentioned at the outset in such a way that the structural outlay for connecting the suppliers to the central control device is considerably reduced and, above all, the adjustment or "marking" the feeders in the feeder group are simplified and can be carried out more quickly.
  • the manual marking of each supplier is omitted due to the electronic switching device, to which an address can be assigned by the central control device.
  • the central control device assigns an address to each electronic switching device, under which each supplier can then be controlled individually during operation.
  • the feeders of the group only need to be fixed mechanically without “marking” and that the textile machine is then immediately ready for operation.
  • Another important advantage is that the line bundle now contains only a small number of lines, since all suppliers are connected to the same lines in the same way, so that the connection can be carried out relatively easily and the construction effort and the space for the accommodation of the line bundle is considerably reduced, since it is no longer necessary to select specific lines or a specific line for each supplier.
  • the line bundle can be structurally integrated into the supply group or the accommodation of the group without difficulty, so that there is little space for the line bundle is required and it no longer hangs around between the individual suppliers and the central control device.
  • the downtimes of the textile machine before start-up, after breakdowns, after conversion work, in which individual suppliers of the group may have been interchanged, after repair or exchange work and in the event of process changes can be drastically reduced.
  • An embodiment is particularly advantageous, as can be seen from claim 2.
  • the adapters of the group are adjusted for the first time, no special care needs to be taken to connect the individual lines to the switching device, as after swapping the positions of adapters of the groups, since the interchanged adapters in turn have the same positions with regard to the lines of the line bundle, as the feeders were previously intended at these locations.
  • the addresses can be allocated to the individual suppliers in the manner of a relay circuit, so that even after such a swap, suppliers of the group can again be individually controlled by the central control device without them had to be "marked" again.
  • Microprocessors are simple, prefabricated and inexpensive electronic components that can be programmed for their respective purpose. They are customary in the trade and, for example as a chip, take up extremely little space for accommodation. It would of course be conceivable to use a customized electronic switching device instead of a microprocessor; however, this would be much more complex as a microprocessor usable for many other purposes, which is programmed 5m with regard to the known steps to be expected.
  • a further, expedient measure which leads to a simplification of operation can be found in claim 8.
  • This additional device in each supplier fulfills the task of localizing and analyzing errors that occur at each supplier and making them recognizable to the central control device so that the latter can stop the textile machine and at the same time indicate the type of error.
  • FIG. 11 expedient.
  • the bundle of lines can be accommodated in the ring-shaped carrier on which the central control device is also attached. This eliminates annoying and space-consuming line connections between the central control device and the suppliers. As is known, the correct connection between the control device and the switching device can be established when the feeders are attached to the ring-shaped carrier.
  • a particularly advantageous application of the subject matter of the invention results in connection with an electronically or electrically controlled ring knitting machine, in which the individual ringing devices are controlled centrally by a so-called model computer.
  • This model computer can be connected upstream of an interface circuit to the central control unit of the suppliers, whereby the central control unit and also the microprocessors in the suppliers can be controlled in parallel with the signals from the model computer, which are also intended for the stripes and, for example, the Show the respective color or a color change.
  • a feeder for positive thread delivery has a housing 1 with a clamping part 3 which can be fastened to a support ring 2 of the knitting machine, specifically with a screw 4.
  • the support ring 2 carries a number of feeders above the knitting systems, which corresponds to the number of systems in the machine (Fig. 6).
  • the clamping part 3 extends with a projection 3a into the housing 1 and divides it into chambers 1a and 1b.
  • the projection 3a extends beyond the housing 1 in FIG. 1 and forms a support plate 3b for a vertical, non-rotatable axis 3c.
  • several (here four) thread guide wheels 5A, 5B, 5C, 5D are rotatably mounted on the axis 3C.
  • a belt 6A, 6B, 6C or 6D runs over each wheel and is driven in synchronization with the knitting machine.
  • the number of yarn guide wheels corresponds to the number of preferably different colored threads for the associated ringing device.
  • All arms 7A inwards, 7B inwards, 7C inwards and 7D inwards for the incoming threads are identical, as are the arms 7A outwards, 7B outwards, 7C outwards and 7D outwards for the outgoing threads, so that only the arms 7A inwards and 7A away, will be described below.
  • an armature plate 8A On the axis of the arm 7A inward is attached an armature plate 8A which cooperates with an "engaging" electromagnet 9A which, when energized, pivots the armature plate 8A clockwise against the action of a spring 10A (upward in Fig. 1) .

  • the solenoid 9A When the solenoid 9A is de-energized, the spring pulls the arm 7A counterclockwise (downward in Fig. 1) against a stop 11A.
  • a support plate 12A for a tension spring 13A (see 13D in Fig. 1) is fixed, the other end of which is fixed to a support plate 14A (see 14D in Fig. 1) , which in turn is attached to the housing 1 by means of a screw 15A.
  • the tension spring 13 pulls the arm 7A outward counterclockwise (i.e. upward in Fig. 1).
  • a outward is an i. w. L-shaped plate 16A with a stop surface 17A for limiting the counterclockwise movement of the arm 7A outwards, an actuating surface 18A and a contact plate 19A.

  • the contact plate 19A of the L-shaped plate 16A cooperates with a fixed contact plate 21A of a protrusion 22A.
  • a contact tongue 24A is fastened to the projection 22A, which extends vertically downward and interacts with the contact cam 20A.
  • actuating surfaces 18A, 18B, 18C and 18D of the other arms 8B outwards, 8C outwards and 8D outwards cooperate with further actuating surfaces 25A, 25B, 25C and 25D of a vertical pull rod 26 which is not attached to an anchor (in FIGS. 1 to 3) shown) of a lifting electromagnet 27 is attached.
  • the pull rod 26 When the electromagnet 27 is energized, the pull rod 26 is moved upwards by a small distance, whereby the arms 7A outwards, 7B outwards, 7C outwards, in the counterclockwise direction, are pivoted into a central position, since the pull rods 26 with their surfaces 25A, 25B, 25C and 25D act on the plates 16A, 1 (B, 160 and 16D on the axes of the arms 7A outwards, 7B outwards,? C outwards and 7D outwards, respectively.
  • the contact cams 20 do not yet work with the contact tongues in the middle position of the arms 24 together.
  • the contact plates 21A, 21B, 21C and 21D and the contact tongues 24A, 24B, 24C and 24D are connected (not shown) with electrical leads to a contact pin 28S of an electrical circuit board 28 which contains a switching device in the form of a microprocessor, which will be described below .
  • contact sockets 29 and 30 are located here on opposite sides of the housing (see FIG. 2).
  • a flat cable with preferably six conductors is connected to each socket, which is used as a so-called “bus line” in order to supply and receive command signals and a supply current C from an electronic central control unit CU, which is preferably attached to the support ring 2 and contains a microprocessor.
  • a contact pin arrangement could also be provided in the chamber 1b, with which the conductors of the bus line in the support ring 2 can then be tapped.
  • plates 31 and 32 which extend outward and four fixed ceramic eyelets 33A, 33B, 33C and 33D for guiding the threads FA, FB, FC and FD and four fixed ceramic eyelets 34A, 34B 34C and 34D, respectively for guiding the threads FA ', FB', FC 'or FD'.
  • the threads are fed positively by the wheels 5A, 5B, 5C and 5D to the tapes 6A, 6V, 60 and 6D and leave the feeder down to a ringing device in which they are gripped by fingers and further down to the needles of the Knitting machine.

  • a lamp 37 is used for optical error display, while a manual switch 38 is used to switch off the microprocessor in the supplier.
  • FIG. 5 shows the microprocessor FMP (feeder microprocessor), for example a so-called “one-chip” microprocessor, in a feeder FUn (n in this case lies between one and fourteen).
  • the microprocessor is supplied with a voltage of 5V (direct voltage) via a voltage threshold, not shown, which only allows 5V from the 24V voltage supply for other switching devices in the supplier, and via the "bus line” in the form of the flat cable with six conductors to identical microprocessors of the two neighboring feeders.
  • the first feeder FU1 and the last feeder FU14 of the group are connected to the control unit CU shown in FIG. 5.
  • the "bus line” contains a line for the voltage supply and five signal lines for controlling the microprocessor in each supplier or for monitoring the system for errors of various kinds. These lines are labeled: RESET, STOP SIGNAL, CLOCK, DATA and STAFETTE. The functions that can be carried out in this way will be described later. It is important that the microprocessors FMP are connected in series in the STAFETTE line, while they are connected in parallel in the remaining lines.
  • the microprocessor FMP is in the supplier to the "trig" contacts 19A / 21A, 19B / 21B, 19C / 21C and 19D / 21D and to the "stop" contacts 20A / 24A, 20B / 24B, 20C / 24C and 20D / 24D on. closed.
  • the microprocessor FMP controls the electromagnets 9A, 9B, 9C and 9D, the lifting electromagnet 27 and the lamp 37 via a driver circuit to which 24V is applied. With the hand switch 38, all functions in the microprocessor FMP can be switched off, with the exception of the transmission of the STAFETTEN- Signal. When the switch is in its "off" position, the microprocessor FMP does not notice any other information that occurs on the "bus line".
  • the central control unit CU in Fig. 5 consists i. w. from a microprocessor CMP (central microprocessor), which is also a "one-chip” microprocessor with a 5V DC power supply.
  • CMP central microprocessor
  • a position sensor SYNC is provided (e.g. a reed switch), which interacts with the drive shaft of the ribbed cylinder of the knitting machine to generate a pulse per revolution of the knitting machine to deliver the microprocessor.
  • a e.g. Photoelectric sensor FREQU cooperates with a toothed disk on the drive shaft of the knitting machine in order to deliver a pulse train with a frequency corresponding to the current speed of the knitting machine to the microprocessor CMP in the control unit CU.
  • the microprocessor CMP is connected to a display DISPLAY in the control unit C which only shows two characters which are used for the optical code display of the type of an occurring error, e.g. a thread bich with the code "1 1" and an error in the signal transmission with the code "2 2" is displayed.
  • the microprocessor CMP in the control unit CU is connected to the "six-wire bus line" mentioned in connection with FIG. 4 for the communication connection with the respective microprocessor FMP in each supplier of the system according to the invention.
  • T1, T2, T3 and T4 denote four hand switch buttons in the area of the central control unit, the function of which is described below.
  • FIG. 6 shows the feeders FU1 to FU14 and the control unit CU on the support ring 2 of the knitting machine. It can be seen how the feed belts 6A, 6B, 6C and 6D are driven by a shaft 39 via a roller 40 with a variable diameter (for changing the belt speed) and a tensioning device 41 with a drive belt 42.
  • the addressing is carried out by the control unit CU, which receives a signal, e.g. sends a binary zero (equals low potential) on the STAFETTEN line when it starts sending out pulse trains on the TAKT line.
  • the signal on the STAFETTEN line enters the FMP1 of the number 1 supplier (FU1), which is programmed to start counting and stores the number of clock pulses in an internal memory which are on the CLOCK line to occurred at that time, ie in this case "one".
  • the signal on the STAFETTEN line continues from the STAFETTEN output of the microprocessor FMB1 in the supplier FU1- to the STAFETTEN input of the microprocessor FMP2 in the supplier FU2, which reads on receipt of the STAFETTEN signal that two pulses have so far been on the CLOCK Line occurred, this number being stored in its internal memory.
  • the STAFETTEN signal continues to move from supplier to supplier until it has passed the last supplier FUm of the group whose microprocessor FMPm reads or counts that m pulses have occurred on the CLOCK line so that this supplier has the address "m" (eg "fourteen") receives.
  • the main advantage of this addressing operation or "designation" of the feeders is that the feeders, if so desired for one reason or another, can be moved or exchanged freely within the system.
  • the position of each supplier in the group can be changed freely, or alternatively a supplier can be replaced by a new supplier without the need for a manual "marking" as in the known system according to European patent application No. 80106719.0 was.
  • the feeders must be "marked” by the position of a specific contact pin having to be matched to a specific wire in the flat multi-conductor cable.
  • the automatically addressing mode of operation in the system according to the invention also eliminates the disadvantage of "marking" by hand for the first time before the ring knitting machine starts operating for the first time.
  • the central control unit CU When such a received signal is received back, the central control unit CU sends one or more commands or command signals on the DATA line, each command signal being a 4-bit word (possible total number of commands sixteen), however only the microprocessor EMP12 that was called is enabled to receive the command signal or that on the DATA line to read or receive signals occurring. If the central control unit does not receive the reception signal immediately after the addressing or calling signal has been sent, it generates an error display or a STOP signal for the knitting machine according to the programming.
  • the "working" arm 7D is pivoted inward counterclockwise, i.e. downward in Fig. 1, thereby pulling the thread FD on the guide wheel 5D under the guide belt 6D and stopping the positive delivery.
  • Operation 2 displaces the pull rod 26, causing the "working" arm 7D outwards, as well as the other arms 7A outwards, 7B outwards and 7C outwards, which may be in their lower position at this moment, for example because of the Elasticity of the threads, a bit in the counterclockwise direction are rotated, ie upwards in FIG. 1, into a predetermined middle position. However, the contacts 20, 24 are not closed.
  • An internal program routine runs in the supplier's microprocessor FMP to ensure that the correct thread is delivered positively, regardless of the fact that interference may occur in the supplier, e.g. due to increased tension due to the elasticity of the straight stopped thread. It can also happen that two output arms are brought into the "trig position" and each generate a trig signal. Then, if the microprocessor FMP had no internal program routine (as described below), two would be compared to the supplier's microprocessor FMP to ensure that the correct thread is delivered positively, regardless of the fact that interference may occur in the supplier, e.g. due to increased tension due to the elasticity of the straight stopped thread. It can also happen that two output arms are brought into the "trig position" and each generate a trig signal. Then, if the microprocessor FMP had no internal program routine (as described below), two would
  • the microprocessor FMP If such a "trig signal” does not occur during this "timeout routine” (duration 20ms), the microprocessor FMP generates an actuation signal at the time t3 + 20ms in accordance with the programming, ie it switches the current to the electromagnet 9D for the old thread on again, so that this has priority and is again delivered positively.
  • the microprocessor FMP in the supplier automatically switches the stop function for the respective output thread guide arm according to the programming only for the thread which gave the "trig signal", i.e. in case 1 for the new thread FA, in case 2 for the old thread FD and in case 3 for the new thread FA.
  • the stop function i.e. that the power supply to the contact cams 20A, 20B, 20C and 20D and the contact tongues 24A, 24B, 24C and 24D is programmed so that it is switched on in all Fournisseren immediately after the "trig signal" occurred in the supplier .
  • the microprocessor FMP in the foumisseur does not respond to the command signal 3 "GIVE STOP TOUCH" because a "trig signal” was received, which means that no error, e.g. a thread break was present.
  • the microprocessor FMP is programmed in every researcher for normal operation in such a way that it immediately sends a stop signal back to the "STOPSIGNAL" line to the central control unit if a thread break occurs in the thread being knitted, so that the knitting machine is stopped and the error display 37 and the display lights up.
  • the current to all "engagement" electromagnets is turned off at the same time, so that the positive feeding of the threads ceases to prevent temporary overfeeding.
  • the operator switches on the restart switch T4 in the central control unit CU (see FIG. 5), as a result of which the microprocessor CMP in the control unit
  • the operator can reset the entire program in the microprocessor CMP of the central control unit CU and the microprocessors FMP in all suppliers, whereupon the entire program is automatically started again when the control unit receives the next synchronization pulse from the position sensor SYNC (see FIG. 5 ) receives.
  • the switch T2 causes the central control unit CU to issue a certain common command to the microprocessors in all the suppliers, so that all the electromagnets 9A, 9B, 9C and 9D are de-energized so that no thread is delivered positively.
  • the trig signal of the "trig contacts" 19A / 21A, 19B / 21B, 19C / 21C or 19D / 21D is designed so that, as before the stop function, it only affects the thread that is being knitted. This way of working can be of considerable importance when starting a new product quality in the machine, i.e. before the speed of the belts 6A, 6B, 6C and 6D (i.e. the thread speed) is correctly set in relation to the speed of the knitting machine.
  • the switch T3 in the control unit CU effects an additional specific command to the micropro cessors FMP of all suppliers, which causes the current to one of the electromagnets 9A, 9B, 9C, 9D, which was actuated by a "trig signal", to remain switched on, whereas the lifting-engagement electromagnets 27 do not as during a machine revolution be excited in normal operation.
  • This special function can be used if the ring knitting machine is to be used for knitting smooth goods.
  • the exemplary embodiment described is intended for a mechanically controlled ring knitting machine, in which the stripes are controlled mechanically by a central control unit.
  • the invention can be used particularly advantageously for an electronically controlled ring knitting machine in which the ring devices are controlled electrically by the central control unit.
  • the information about the color change or thread change is electrically accessible in the central pattern program system of the knitting machine itself. This means that in this case there is no need to temporarily raise the arms 7A outwards, 7B outwards, 70 outwards or 7D outwards to a "middle" position and for lowering the arms by the new thread. Since the temporary lowering of the output thread guide arms is not necessary, no "lifting" - Electromagnet 27 needed. It is then also unnecessary to block the stop function for the output yarn guide arm at the moment when the central control unit sends a command to end the positive delivery in the respective supplier.
  • the microprocessor CMP is programmed to give a command for positive delivery to the respective supplier and at the same time to inform the microprocessor FMP in the supplier which actuates the four "engagement" electromagnets 9A, 9B, 9C or 9D shall be.
  • stop function is switched on only for the thread that has been commanded by the central control unit CU for positive delivery.
  • the microprocessor CMP of the central control unit CU is designed or programmed from the start with various tabular information in its internal memory (the tabular information depending on the number of knitting stations of the machine, the spacing between the knitting stations and the like), that it is determined which operations are to be carried out in all suppliers, in which order these operations are to be carried out and at what times these operations have to be carried out.
  • the times at which these operations must be carried out are determined by determining at which pulse in the Rilszug they must be started by the pulse generator FREQ, the synchronization pulses which the microprocessor receives from the position sensor SYNO being counted.
  • this tabular information for the microprocessor CMP in the central control unit CU need not be so extensive, since in this case the microprocessor CMP works “on-line” with the knitting machine pattern computer, This is done via an interface circuit IC (FIG. 5, indicated by dashed lines) and therefore continuously receives information from this sample computer PC which gives it the necessary color change data with each machine revolution.
