Description

The invention relates to textile yarn processing processing machines and relates in particular to control devices for such machines, e.g. spinning and twisting machines, which make it possible to automatically bring about movements of the ring rail in such a way that full by hand or automatically Package of yarns that have been formed from a treated or processed yarn are withdrawn, and that again beginning to form new packages from processed yarn.

With the usual textile yarn processing machines, e.g. spinning and twisting machines are each several rotatable spindles are available which are generally straight in shape on either side of the machine in question are arranged and carried by an upright frame of the machine. There is also a hanging bench facility

509831/0497

present, which can be moved up and down in a vertical direction opposite each row of spindles from this side of the machine and serves to lead the yarn processed by the machine to the spindles in each case according to a predetermined pattern to form wound bodies of processed yarn to build. There are also bobbin-forming devices which are connected to the ring rail and serve to move the ring rail up and down according to a predetermined program during normal processing of yarn. After such yarn packages have been formed on the spindles of the machine from the processed yarn, it is necessary to move the ring rail device down so far that it ^{assumes a lower position below the spindles in comparison to} its normal operating position in order to be able to pull it off of full packages or spools of treated thread from the spindles.

Up to now this is usually done with the help of a pedal ~ - device causes on which the operator puts one foot, to then the pedal with his body weight after to press down so that the ring rail is brought into its removal position. For this purpose it is necessary to have a to apply great force of about 4-5 to 90 kg when the Ring bench should be lowered. Of course, an operator must operate the ring rail of a yarn processing machine to operate in this way must have sufficient physical strength and be large enough to enable it can muster such a force, and therefore the

509831/0497

The jobs concerned are normally not occupied by short people or women.

Furthermore, when the yarn processing machines are started up again after the yarn package has been drawn off the ring banks of the machine in question are lifted again by the coil forming devices and put into their working position and the operator uses the pedal assembly to "start processing yarn" again and initiate the formation of new packages on the spindles. Since the yarns during this renewed start-up usually sag or form loops or free ends of yarn, the operator must press the pedal device Depress again to lower the ring rail sufficiently while the machine is restarted is, and this is done independently of the bobbin forming devices, so that the slack, loops and free yarn ends can be eliminated so that the renewed start-up takes place without errors. "Will the processed from the Yarn-formed package later subjected to further processing, it is also desirable at the bottom End of the package a fastening or holding end or to produce a bundle of yarn. For this purpose, the ring rail is usually by the operator along a short distance alternately up and down to form such a yarn bundle at the lower end of the yarn package.

Various devices have already been proposed to make it easier for the operating personnel supposed to move the ring banks as it is to pull off

further comprises numerous rotatable spindles 12 supported by the frame for receiving reels which are used for this purpose serve to wind up yarns Y in the course of their processing by the machine. Furthermore, the machine 10 includes a Ring rail 14, which is moved vertically up and down relative to the spindles 12 in a known manner in order to close the yarn to guide the bobbins placed on the rotating spindles, according to a predetermined program in such a way that that the yarn Y forms several layers for each bobbin, from which a package of processed yarn is formed will. As is known, the package of yarns are built up from successive layers of yarn, the axial length of which is shorter is than the length of the spindle; this generally begins at the lower end of each spindle 12 and progresses advanced above, so that yarn packages are formed, the general shape of which can be seen in the drawings.

509831/0497

If necessary, however, it is also possible to form yarn bodies of a different shape.

Furthermore, the machine 10 has coil forming devices which are coupled to the ring rail 14 and to it serve, the ring rail along the spindles 12. during the normal yarn processing process after a predetermined Move the program up and down. These coil forming devices include a plurality of crank arms 16 between their Ends swivel-mounted on associated parts of the stationary machine frame 11 with the aid of bearings 17 are. The crank arms 16 are each connected at one end 18 to a common connecting rod 19, and their other ends 20 each work with the adjacent end of one of several Ringbankhubstangen 21 together, which at their upper ends are connected to the ring rail 14. Each crank arm or lever arm 16 has a counterweight 24 on, which protrudes to the outside with respect to the fixed bearing 17 and serves to. the bell crank. 16 to be pre-tensioned in the position in which the lifting rods 21 together with the ring rail 14 assume their highest position.

So that the biasing force of the counterweights 24 is counteracted can be so that the ring rail under the effect of its own weight in the course of its up and down movement can lower compared to the spindles 12, a bobbin formation chain 26 is present, which with one of the angle levers 16 is coupled and can be operated by further devices to be described to back and forth to be moved so that the angle lever 16 against

5 0 9 8 3 1/0497

move the direction in which they are biased by the weights 24 so that the ring rail 14 together with the lifting rods 21 lowers under the action of gravity in order to carry out the desired downward movement. The chain is gradually lowered during these up and down movements, so that the ring rail 14 along the spindles 12 gradually performing up and down movements, which are started at the lower end of the spindles 12, and the as soon as the upper end of the spindles is reached.

The drawings show only one side of a typical yarn processing machine, but it should be noted that another series of rotatable spindles 12 is typically located on the other side of the machine 10 of FIG. Further devices that are present in a typical yarn processing machine 10, for example the devices for driving the spindles 12, are not shown in the drawings, since a more detailed explanation of these devices should not be necessary for an understanding of the invention. Rather, the structure and mode of operation of these devices are familiar to every person skilled in the art. The above reference to FIG. 1 described devices a typical spinning or twisting machine and its mode of operation in the processing of yarn are also known to anyone skilled, so that a more likely E _r unnecessary purification.

After Y package has been formed on the spindles 12 of the machine 10 from the processed yarn, must

509831/04 9 7

the ring rail 14 can be lowered to a position which is below the lowest position, which it during the nor-. paint processing of yarn achieved; this position can be seen from FIGS. 1 and 3; in this position the finished package can be withdrawn from the spindles 12. To bring about this movement automatically without a Pedal needs to be operated, or that the operator has to carry out other work steps, is through the Invention, the control device described in more detail below has been created. This device makes it possible in a fully automatic way to prepare the machine for pulling off the bobbins and it comes into operation automatically, when the formation of bodies of processed yarn is finished, and further, it stops the machine after the completion of the bobbin withdrawal process automatically back into operation »

To this end are still to be described, using a pressure medium actuatable devices are present, which are in connection with the coil forming devices and serve to carry out several work steps one after the other; The first step is the ring rail 14 from the position it occupies according to FIG. 2 after a bobbin is completed, occupies, lowered and in the position shown in Fig. 3 below the Spindles 12 brought to enable the withdrawal of the bobbins, whereupon the finished bobbins with the yarn packages withdrawn from the spindles 12; the second step is that the ring rail 14 with the help of Spool forming devices, to which the counterweights 24 belong, in a yarn processing position close to the lower ones

509831/0497

Ends of the spindles is raised, which is indicated in Figure 4 with dashed lines; in the third step, the ring rail 14 is near the rear end of the Spindles moved up and down a short distance to remove any slack in the yarns and to cause a yarn bundle to be generated on each spindle after the machine is restarted, as it is indicated in Fig. 4; the fourth step consists in that the ring rail 14 is released, in order then to be so controlled by the coil forming devices that the yarn processing operation takes place in the normal manner, as shown in FIG. One time-dependent electrical control circuit, which is described in more detail below, is with the help of a Pressurized means operable devices and the ring rail 14 connected and designed so that it allows depending on the predetermined positions shown in Fig. 2 to 5 of the ring rail, which with the help of a Pressurized means to actuate devices or to make them ineffective or to control them so that they several carry out successive work steps.

According to FIGS. 1, 6 and 7, the devices which can be actuated with the aid of a pressure medium include a plunger. a cylinder 31 and a piston 30, the cylinder of which is hinged to one of the angle levers 16, while the piston rod of the piston 30 is articulated to the stationary frame 11 of the machine. According to Fig. 7 is a Pressure medium line 34 · present, which is not from a pressure medium source shown from to the cylinder 31

509831/0497

extends'and it enables the pressure medium as required one side or the other of the piston 30 to be supplied. In the pressure medium line 34 is shown in FIG. 7 by hand adjustable needle valve or another throttle valve 36 switched on, so that the supply of the pressure medium to can regulate the cylinder 31 and the return of the pressure medium from the cylinder and thus also the speed, with which the ring rail 14 is raised or lowered.

While the named pressure medium source is not shown in Fig. 7, Fig. 1 shows that for supplying the pressure medium to the line 34 and the cylinder 31, a pressure vessel 38 is present, to which an electrically drivable pump 39 is assigned, by means of which the pressure medium from the container 38 via the conduit 34 to the cylinder 31 is funded. As soon as this happens, the cylinder 31 moves to the right according to FIGS. 1 and 7, so that the Crank arm 16 is pivoted down to die.Verbindungsstange 19 also to move to the right, so that the other crank arms or angle levers 16 accordingly be pivoted, wherein the free ends 20 of the crank arms are moved downward so that the ring rail 14 is below the effect of its own weight can move down until it reaches the reel playback position shown in FIG reached, in which it assumes a lower position than in the course of its normal up and down movement. On the tappet 30, 31, an adjustable collar part 40 or the like can be attached, which enables the retraction movement of the To limit the piston 30 relative to the cylinder 31 and thereby the position of the ring rail 14 at its lowest position

_ ₁₆ -? 4 3 9 6 1 7

i.e. the bobbin withdrawal position.

If the plunger 30, 31 is rendered ineffective in that the pump 39 is stopped, the cylinder moves 31 under the action of the counterweights 24 again to the left, so that the ring rail 14 is brought back into its working position whereupon it is passed through the coil forming devices with the coil forming chain in a manner yet to be explained 26 is controlled.

Since the plunger 30,31 is present, it is natural no longer required to depress a pedal or other manual device to operate the ring rail 14 so that the package is removed from the bobbins 12 can be deducted.

Regarding the automatic control device according to the invention Part of preparing the machine for removing the bobbins and restarting the machine a locking device that makes it possible to automatically lock and set the ring rail 14 as soon as the ring rail reaches the bobbin withdrawal position, and which the ring rail automatically releases again when the machine is put back into operation. According to FIG. 7, this locking device includes a locking member 45, between its ends - by means of an axle 46 on the frame 11 of the machine is pivotably mounted, carries a counterweight 47 at one end and a counterweight at the other end Has locking element 48. The locking element ″ 48 of the locking member 45 works with a projection 51 together, the opposite of one of the crank arms 16 to the outside

- 17 -. ? 439617

protrudes as soon as the ring rail 14 is brought into its bobbin removal position, around the associated crank arm 16 and thus also fix the ring rail in the bobbin withdrawal position. The locking member 45 is through a rod 49 which is on the locking member is hinged between its ends, connected to an electromagnet 50, which makes it possible to pivot the locking member 45 against the action of the associated counterweight 47 when it comes out of the The unlocking position according to FIG. 6 has been brought into the locking position shown in FIGS. 1 and 7. Of the Electromagnet 50 is with that already mentioned, in the following described in more detail, time-dependent operating control circuit connected, and he is operated, .as soon as the ring bank 14 is brought into the bobbin withdrawal position; when the machine is restarted, the electromagnet is activated switched off to release the ring bank again.

The textile yarn processing machine 10 has, according to FIG. 1, so-called pig tails 55, which generally have the axes of the various spindles 12 and above the Spindles are arranged and serve the yarn Y of the ring rail 14 and the spindles 12 during processing of the yarn. Are these pigtails 55 in their Normal position on the spindle axes and arranged above the spindles, they hinder the paving of the paver Package from the spindles. In order to avoid this disadvantage, the pig tails or yarn guides are shown in FIG 55 jointly pivotable by means of axles 56 mounted on parts of the stationary machine frame 11 in such a way that

509831/0497

that they move out of their normal position of use on the axes of the spindles and above the spindles (Fig. 1) according to FIG. 20 in a bobbin withdrawal position from the spindle axes Swivel away so that the finished package can be pulled off the spindles.

So that the yarn guides 55 can be moved between the two positions described above connected to them is a device that can be actuated with the aid of a pressure medium or a plunger, to which a cylinder 58 and a piston 57 include; with the piston 57 and the cylinder 58 is one encased in each case Wire rope 59 connected. The plunger 57 j 58 is open part of the stationary machine frame ^ 11 by support pieces movably connected, which are attached to the sheaths of the wire ropes 59, so that the plunger according to FIG. can move back and forth. One wire rope 59 extends to the yarn guides 55 on one side of the machine 10, while the other wire rope 59 extends to the yarn guides 55 on the other side of the machine. On each side of the machine 10, the yarn guides 55 are interconnected so that each set of yarn guides as a whole with the help of the. yet to be described in more detail actuator between the two described Positions can be moved.

The device which can be actuated with the aid of a pressure medium includes a pressure medium source, which is supplied by the already Pump 39 described with reference to FIG. 1 with the container 38 can be formed. According to Fig. 1 extends a

509831/0497

Pipeline βθ from the pump j59 to a solenoid valve 62, from which further pipelines 6j> and 64 lead on opposite sides of the piston 57 to the cylinder 58, as shown in FIG. 6 and 20 is shown. The solenoid valve is connected to the electrical control circuit already mentioned and explained in more detail below, so that it can be actuated in order to conduct the pressure medium from the line 60 via the line 63 to the plunger 57 * 58, so that the cylinder 58 is relatively move towards one another and the piston 57 towards one another and thereby exert tensile forces on the wire ropes 59 in the associated sheaths. The yarn guides 55 are pivoted into their bobbin withdrawal position, in which they are separated from the axes of the spindles 12 by a distance, as shown in FIG. If the solenoid valve 62 is switched off, the pressure medium flows from the line 60 via the line 64 to the plunger 57 * 58, so that the parts of the plunger move apart again, the wire ropes 59 being advanced to the yarn guides 55 back into their to pivot normal operating position in which they are generally axially aligned with the associated spindles.

As mentioned, the automatic control device according to the invention has to prepare the bobbin withdrawal process and for restarting the machine 10, a time-dependent electrical control circuit which with the device for actuating the ring rail, the electromagnet for locking the ring rail and the plunger for Pivoting the twine guides is connected. This control circuit is operated depending on the fact that the

50983 1/0497

Ring rail occupies or reaches predetermined positions, so that the devices mentioned are controlled in such a way that they carry out the above-mentioned work steps in the intended Carry out sequence.

According to FIG. 6, the time-controlled electrical control circuit has a normally open first switch 70 which is arranged so that it is automatically actuated as soon as the ring rail 14- is brought into its uppermost position according to FIG. 2, as is the case at the end of the formation of packages on the various spindles 12 happens. To enable this actuation, a stop 71 is attached to the connecting rod 19 for the angle lever 16. If the chain 26 of the bobbin-forming device is gradually lowered while the package of yarns are being formed on the spindles 12 from bottom to top, the connecting rod 19 is moved progressively to the right as shown in FIG. 6. When the ring rail according to FIG. 6 has covered the distance A, the connecting rod 19 will have covered the distance A ^{1 according to FIG} turn on electrical control circuit.

The control circuit also includes a timer which is connected to the first switch 70 and which is also actuated when it is actuated; for this timer is a timer motor 73 e3.ektrischer consulted in accordance with Einei ¹ · shaft 74 'with which Figure 6 eight cams are non-rotatably connected C1 to C8. of course you could if necessary

509831 / G497

also provide any other number of cams. Each of these cams has one of eight switches S1 to SS that can be brought into two different positions, each having a movement take-off member which is supported on the associated cam so that it is each of these. Switch enables two circuits connected to the relevant contacts to be switched on or off. The cam-controlled Switches S1 to S8 are in electrical connection with the pump 39 for the pressure medium for lowering the Ring rail 14, the electromagnet 50 for controlling the locking device and the solenoid valve 62 for controlling the Thread guides 55

Furthermore, the control circuit has a second switch 80 which is connected to the normally closed circuit of the cam-operated switch S4- and the normally open circuit of the cam-operated switch S5 and the electric motor of the pump 39 and is operated when the ring rail 1: 4 according to Mg. 4- is brought into its yarn bundle formation position when the machine is restarted, in relation to which it is alternately moved up and down. The second switch 80 is normally closed and is controlled by a stop 81 which protrudes downward from the connecting rod 19 and opens the normally closed circuit of the switch 80 when the ring rail 14 is moved along the path B according to FIG the stop 81 is also moved along the distance E ¹ . The second switch 80 has a movable contact that is only opened to open the associated circuit when

S09831 / 0A97

the stop 81 is moved from right to left according to FIG. 6, because the upper part of the switch 80 is pivoted as soon as the stop 81 comes to rest on the switch, while the stop according to FIG. 6 moves from left to right emotional.

Further, the control circuit of Figure 6 has a normally open, hand or other manner actuatable push-button switch 85 on, which is on the timer motor 73 and the cam-actuated ones to be described in more detail Switch S1 to S8 is connected and in addition • is used to operate the control circuit after the finished Packages have been withdrawn from the spindles 12 and when the machine 10 is to be started again. There is also a main motor 88 driving the machine 10, which is controlled by a switching relay 89 of any type is controlled and serves the spindle drive device, the reciprocating bobbin forming devices and to drive other devices of the yarn processing machine 10. After all, a normally closed one Switch 91 is present, which serves as a safety switch and if necessary it enables the entire control circuit to be put out of operation.

Is closed when the control circuit of FIG. 6 of the normally open switch 70 characterized in that the ring rail 14 reaches its highest position according to FIG. 2, after have been formed on the spindles 12 yarn package, indicating that the coil now _Z ready for stripping are, the circuit of the timer motor 73 is closed to

509831/0497

to operate the timer motor so that cams C1 to C8 are rotated. The cam CI now closes switch S1 to complete the associated normally open circuit to allow power to flow to the timer motor 73 is fed. And this engine regardless of the position of the switch operated by the Hingbank is kept in operation for a predetermined period of time can be. This now closed circuit of switch S1 now carries a current, so that the timer switch S3, S4, S5, S7 and S8 can be activated.

During the operations just described, the Kingbank 14 is caused to make a downward stroke corresponding to its perform normal movement in the formation of gaxn bodies, after which it makes an upward movement over a distance, about half the normal stroke length at the end of the bobbin formation process under the controlling effect of the Corresponds to coil forming devices; as soon as this is done, the cam C3 has rotated so far that it has the Switch S3 operated to the associated, normally to close an open circuit. Now the current flows through the closed circuit of switch S3 and normally closed circuit of the switch S4 to the electric motor driving the pump 39, so that the pressure medium via line 34 and valve 36 to the plunger 30 »31 is promoted to lower the einbank and them to bring into their bobbin removal division according to FIG. 3. Be it notes that the normally bridged connection of switch S3 is not used here.

50983170497

While the ring rail 14 is being lowered to its spool withdrawal position, the timer motor 73 will operate all eight Cams C1 to 08 to rotate 180 degrees; during this the following processes take place.

The cam C8 is rotated into such a position that it closes the normally open circuit of the switch S8 to deliver to the current to the solenoid valve 62 so that this valve is actuated, the pressure medium from the pump 39 bms via lines 60 and 63 to the floating plunger 571 58 so that the wire ropes 59 are withdrawn to pivot the yarn guides 55 upward into their position according to FIG. No use is made of the normally bridged connection of switch S8.

Power is supplied to main motor 88 via relay 89 and the normally closed circuit of the cam operated Switch S2, and as soon as the Kingbank 14 is in its lowest position, i.e. the bobbin removal position, reached, the cam C2 opens the normally closed circuit of the switch S2, whereupon the main motor 88 turns off and gradually comes to a standstill. In this way it is possible for known purposes Wrap four or five turns of Y yarn around each spindle 12 underneath each bobbin. Simultaneously the normally open circuit of the cam operated switch S2 is closed to supply the current to the normal-

S0 98 3 1/049 7

wise open, hand-operated push button switch 85 for a purpose yet to be explained.

As soon as the ring rail 14 according to FIG. 3 has reached its bobbin withdrawal position below the spindles 12, the timer motor 73 has rotated all cams C1 to C8 by 180 °, and the cam C7 opens the normally; closed circuit of switch S7> which is connected in series with the now closed, normally open circuit of switch S1 to stop the timer motor 73 so that the rotation of the cams C1 to C8 ceases. The normally open circuit of switch S7 is not used here. At the end of the 180 ° rotation of the cams C1 to C8, the cam C4 has closed the normally open circuit of the switch S4 to actuate the solenoid 50 so that the locking member 4-5 is pivoted to bring the locking element 48 into its locking position so that the ring rail 14 is set against the normally effective biasing force of the counterweights 24 in its lowermost position, ie the bobbin pulling pitch. By opening the normally closed circuit of the switch S4, the pump is brought to a standstill, so that the plunger 30 * 31 for lowering the ring rail is rendered ineffective. °: ■

The yarn processing machine IQ is now prepared for that the filled bobbins by an automatic pulling device or by an operator with the Hand peeled off. The ring rail 14 is in its lowest position or the bobbin withdrawal position according to FIG. 5 below

509831 / 04.97

of the spindles 12 have been brought, and the control circuit according to Fig. 6 your program has run and is switched off been. Furthermore, the locking member 45 has locked the ring rail 14 in the bobbin removal position, and the Yarn guides 55 have been pivoted into the bobbin withdrawal position in which they are no longer in axial refugee with the Spindles 12 are so that the finished body of processed yarn Y can be withdrawn from the spindles.

After the bobbins have been drawn off, the yarn processing machine 10 is ready for the next work cycle to go through after new bobbins or other bobbin carriers on the spindles 12 automatically or with have been put on by hand, so that the yarn processing process can be started again and it is possible is to form new bobbins or bodies of processed yarn on the spindles. Now the push button switch 85 either by hand or automatically by a Automatic device for pulling off and then putting on new bobbins operated. The circuit of the push button switch 85 is previously described by closing the normally open circuit of the cam-actuated Switch S2 has been activated. The push button switch 85 is kept closed so that the timer motor 73 current is supplied again, so that this motor starts up again and begins, the! Lure C1 to C8 a second Rotate 180 ° times. This immediately causes the cam operated switch S7 to be normally closed Circuit closes again after this circuit is triggered by cam C7 at the end of the first rotation by 180

509831/0497

had been opened to the current via the normally open circuit, now closed by switch S1 to the timer motor 73, so that this motor regardless of the position of the push button switch is kept in operation, which can now be released again.

The normally open circuit of the cam operated switch S6 is now closed to remove the power to be fed to the main motor 88 of the machine 10 via the relay 89, so that the machine resumes normal cooking. According to the invention here is the normally closed circuit of switch S6 is not used. The cam operated switch also closes S2 the normally closed circuit that was previously opened to allow the current to flow in the normal way Main motor 88 feed so that switch S6 can reopen its normally open circuit without that thereby the supply of power to the main motor 88 is interrupted. .

During this second 180 ° rotation of cams C1 through C8, cam C4 is normally open circuit of the switch S4-, which had been closed at the end of the first rotation of the cam C4- through 180 °, to turn off the electromagnet 50, 'so that the locking member 4-5 under the action of its counterweight 47 can swing into its unlocked position. As soon as this happens, the ring rail 14 can move under the influence of the on the crank arms 16 acting counterweights 24- again

509831/0497

begin to move upwards to their normal working position to take. In addition, the cam C8 has rotated enough that the normally open circuit of the switch S8 has been reopened to turn off the solenoid valve so that it can return to its normal position can, in which the pressure medium via line 44 of other side of the piston 57 in the cylinder 58 is supplied is to advance the wire ropes 59 so that the yarn guides 55 are pivoted back into their normal working position in which they are in axial alignment with the spindles 12 and are arranged above the spindles.

The ring rail 14 now moves up into a normal processing position from which it initially moves moved up and down a short distance a number of times to build up layers of yarn near the lower end of the spindles 12, until the ring rail has approximately reached the position indicated by dashed lines in FIG. 4. Once this has happened, the squat C5 has turned so far that it has closed the normally open circuit of switch S5 to supply power through switch 80, so that the pump 38 is put back into operation, to operate the plunger $ 0.31 and thus the ring rail 14 to cause to move together with the crank arms 16 downwards. According to the invention, the normally closed circuit of switch S5 is not here used.

The downward movement of the ring rail 14 eliminates the slack and loops in the yarns Y, which

609831/0497

connected to the various spindles 12, and the stop 81 is caused to open the switch 80, as soon as the ring rail reaches the lower end of its lifting distance for building up yarn bundles, as shown in FIG is. When the switch 80 is opened, the pump 39 becomes stopped, whereupon the ring rail 14 begins to, under the action of the counterweights 24 on the crank arms 16 to move slowly upwards. As a result, the stop 81 caused to close the switch 80 again to put the pump 39 back into operation, so that the ring rail again caused by the plunger 30, 31 to move down to move. This creates an up and down movement of the ring rail near the lower ends of the spindles, so that when the machine is restarted, bundles of yarn on the lower ends of the spindles or bobbins being constructed. In the case of warp yarns, each of these yarn bundles would contain about 3 or 4 turns, while in Weft yarns wound an amount of yarn from about 1.80 to about 11 m would. The amount of yarn that is wrapped around the bottom of each spindle while using this bundle of yarn is formed by the circumferential length of the part of the cam C5 having the larger radius agrees; when the normally open circuit of switch S5 is reopened by cam C5, the supply of the current to the switch 80. interrupted, so that the working step to form yarn bundles.

After the cam C5 has finished its work cycle and the timer motor 73 has rotated the remaining cams the second time by 180 °, all switches S1 to S8 are in theirs

60983 1/0497

1 4 ό yb

normal position returned and the timer motor 73 has been switched off. The control of the ring rail 14 is now taken over again by the coil forming devices, which then allow another work cycle to run for the formation of yarn bodies on the spindles 12. It can be seen that the normally closed circuit of switch S1 allows the electrical control circuit with Using the hand-operated push button switch 85, if this is desired, in order to initiate a working cycle independently of the fact that this is done by switch 70 and depending on the position of the ring rail 14 happens.

As described above, the control circuit according to the invention enables automatic sequential operation to operate the ring rail, the device for locking the ring rail and the thread guides so that a working cycle to pull off the filled bobbins and to restart the machine expires, in which the ring rail in their The bobbin withdrawal position is brought and fixed in this position, in which the twine guides are moved in such a way that that they are no longer in axial alignment with the spindles, and in which the ring rail during the renewed Starting the machine is moved so that the slack and the yarn loops by lowering the ring rail against the Influence of the coil forming device is reduced, and also counter to the action of the coil forming devices small bundles of yarn can be built up on the lower ends of the spindles.

509831/0497

The control device according to the invention for preparation of the machine 10 for drawing off the bobbins further preferably has improved bobbin forming devices, to which an automatic reset device is assigned, which makes it possible to connect the coil forming devices so that automatically retrieve that the ring rail is brought into the bobbin withdrawal position. Until now it is In the known coil forming devices, it is necessary for the operator to use these devices after they have been drawn off resets the bobbins or by hand while it is being pulled; according to the invention this working step however, it is now carried out automatically, i.e. it is no longer necessary to use the ring rail to pull off the bobbins and to restart the machine, e.g. to lower it by hand, and also need the bobbin forming devices no longer to be reset by hand, so that a control device is created by the invention which makes it possible in an automatic way, a yarn processing machine for pulling off the bobbins to prepare and to let the machine start again after installing new bobbins.

According to the invention, the coil forming devices is a rotatably mounted, drivable coil forming cam 100 (Fig. 1) assigned, which is rotatably mounted on a part of the stationary machine frame 11 and 11 has a predetermined profile such that from the processed yarn package under implementation a predetermined work sequence can be formed. The spool forming cam 100 is driven by the main motor 88

50983 1/049?

of the machine 10 driven and controlled by the electrical control circuit described above so that it comes to a standstill when the main motor 88 is switched off and the ring rail 14- locked in its bobbin removal position will.

11, there is a coil forming arm 102, one end of which on the stationary machine frame 11 is rotatably mounted, and which has a movement take-off member 10 $ which is arranged to be with the spool forming cam 100 cooperates to create the spooling arm 102 according to FIG. 11 to pivot up and down.

On the free end of the spool forming arm 102 is 19, a ratchet device 105 is arranged, which has a lever arm 106 which is pivotably mounted on an axle stub 107 built into the coil forming arm 102 is. A spring 108 biases the lever arm 106 against a stop 109 on the coil forming arm 102. On the Lever arm 106 is a pawl 110 pivotally mounted by means of a pin 1115 this pawl is by a Spring 112 is pretensioned so that it tries to remain in contact with a stop 11 $ of lever arm 106. In a support bracket 116 fastened to a part of the stationary machine frame 11 is a stationary adjustable one Screw 115 installed, which forms a stop «The latch device 105 is arranged so that it can be used during Each forward and backward movement of the bobbin forming arm 102 comes to rest against the stop 115.

According to FIGS. 11, 12 and 19, a 107 is on the shaft

ratchet wheel 120 rotatable in one direction only, with

509831/049 7

which the pawl 110 of the pawl device 105 cooperates in such a way that that during the reciprocation of the bobbin forming arm 102 the pawl assembly 105 to abut comes to the stop 115, whereby the ratchet device relative to the bobbin forming arm 102 is moved so that the Ratchet wheel 120 is moved step by step, since the pawl 110 slides over a tooth of the ratchet wheel and then in The next tooth is engaged when the pawl is pivoted against the biasing force of the spring 112. These Movement of the ratchet device 110 plays against the The biasing force of the spring 108 so that the ratchet device moves away from the stop 109.

11 and .12 is with the "shaft 107, which in rotatably mounted on the bobbin-forming arm 102, a worm 125 is rotatably connected, which by the ratchet 120 at each ' Operation of the ratchet wheel is rotated by a certain amount of angle.

Furthermore, according to FIG. 11, there is a worm wheel 126, which is rotatably supported on a stationary shaft 127 which is built into the coil forming arm 102; the Worm gear 126 is in engagement with 'the' as shown in FIG Auger 125 so that it is with each incremental rotation. the worm is rotated by a corresponding angular amount. The worm wheel 126 is on a flat side with Ratchet teeth 128 provided. .

The coil forming device also includes a Drum device 130, which is rotatably mounted on the axis 127 and is arranged so that it corresponds to the worm wheel

609831 / 04-97

is facing. The flat side of the drum device 130 facing the worm wheel 126 has, according to FIGS 18 has a plurality of pawl devices 132 which, as shown in FIGS. 13 and 18, are pretensioned by springs 133 which are shown in FIG matching recesses 134- on the flat side in question the drum device 130 are arranged; the pawls 132 each have an outwardly protruding one Tooth 135 on, and these teeth can cooperate with the teeth 128 of the worm wheel 126, so that when the worm wheel is rotated by a certain angular amount, and the drum 130 by a corresponding amount is rotated. For a purpose yet to be explained, however, it is also possible to place the drum 130 in the opposite direction Direction to rotate when the pawls 132 are pressed against the biasing force of the springs 133 into the recesses 134 · so that teeth 135 can slide over teeth 128.

As mentioned, one end 26 'is the coil forming chain 26 according to FIG. 14 is fastened to the drum 130, and the chain 126 can be seen in that of FIGS Wrapped around the drum 130 in a manner. The coil formation chain 26 is drained or unwound by a certain amount each time the drum 130 is thereby is rotated stepwise so that the coil forming arm 102 is pivoted up and down to the crank arms 16 under the action of the weights 24- shown in FIG swing down or to the left so that the Kingbank 14 with each incremental unwinding movement of the chain

50983 1/0497

26 is moved up a small step. aside from that are under the influence of the bobbin-forming cam during each reciprocating movement of the bobbin forming arm 102 100 the crank arms 16 pivoted back and forth to the ring rail 14- raise and lower. It can thus be seen that the ring rail 14 up and down movements along a short stroke of preferably about 75 21m along the Axes of the spindles 12 executes and at the same time along the spindles gradually up to the upper ends of the Spindles is moved while the bobbin forming chain 26 is gradually unwound from the drum I30.

As soon as the ring rail 14 reaches its highest position, in which the coils are completely wound, as shown in FIG Fig. 2 is shown, the ring rail with the help of the means described above is down into its bobbin withdrawal position moved according to Fig. 3, and here the chain 26 must be rewound on the drum 130, so that the next package can be formed from the processed yarn after the yarn processing machine 10 has been put back into operation.

So that the chain 26 can be automatically rewound on the drum 130, the drum is provided with a Torsion spring 140 is provided, which is housed in a recess 141 on the other flat side of the drum. One end of the torsion spring 140 engages a slot 143 (Fig. 14) in the wall 14-1 of the drum I30, while the other end of the torsion spring engages in a slot of the axle 127, so that the torsion spring when Unwinding the bobbin-forming chain 26 from the drum I30

509831/0497

is stretched or raised.

As soon as the ring rail 14 has been lowered to below the spindles in order to take up its bobbin removal position, as shown in Fig. 3, the bobbin forming arm becomes 102 is moved downward by the chain 26 and brought into a position in which the movement dewatering member 103 is lifted down from the crouch 100. Since according to Pig. 11 of the coil forming arm 102 to the plant comes to a stop 148, the drum 130 essentially completely unwound chain 26 relaxed so that it sags * Since the torsion spring 140 is tensioned this slack in chain 26 enables torsion spring 140 to rotate drum 130 in a direction which is opposite to the direction in which it is normally rotated by the pawls 132, which slide over the teeth 128 of the worm wheel 126, so that the chain is back on the Ö.'roimnel 130 is wound up.

Thus, the chain 26 is automatically rewound on the drum 130, and once this is done, are the bobbin-builders ready to restart the machine 10 and with the formation of new packages on the spindles 12 to begin. As the main motor 88 of the machine by the electrical control circuit described is controlled, the cam 100 is brought to a standstill in a predetermined position, so that then, if the ring rail 14 is raised during the described restarting of the machine, the movement stop

509831/0497

taking member 105 of the bobbin forming arm 102 again Contact with the bobbin formation cam 100 comes as soon as the ring rail is indicated in FIG. 4 with dashed lines Position reached, whereupon the cam 100 begins to rotate again when the main motor 88 is powered by the electric Control circuit is put back into operation.

The coil forming device according to the invention can furthermore according to FIGS. 13 and 16, the rewinding of the Chain 26 have limiting device in the form of a slotted collar part 150 with the axis 127 through a transverse screw 151 is clamped, and in the one threaded adjustable stop member 155 is installed, which protrudes from the collar part 150 and with a stopper 154 built into the spool forming arm 102 is, cooperates when the chain 26 with the help of the Torsion spring 14-0 rewound on drum 150 will. The cooperating stops 155 and 154- limit thus the rotary movement caused by the torsion spring the drum 150 such that the means for winding of the chain 26 winds the chain only over a predetermined part of the circumference of the drum 150.

According to the above description, the invention provides a fully automatic control device has been created, which makes it possible to use a 'yarn processing machine to prepare to pull off the finished bobbins and to start the machine again, "and that is used to control the movements of the Kingbank so that they successively the required movements when pulling off the bobbins and when restarting the
