so that the device co-operates with a device that continuously supplies the material at a constant speed.

Automatic thread transfer devices for automatically transferring a running thread from a bobbin on which a yarn package has just been formed to another bobbin are well known in the textile industry. Exemplary of such automatic thread transfer devices is U.S. Patent No. 3,876,161 which is directed to a winder for yarn and similar materials. This winding device has an automatic yarn transfer device which comprises a drive roller and at least two rotatable bobbin carriers, each of which is suitable for receiving a bobbin tube and can be moved into and out of engagement with the drive roller. A thread transverse guiding device swings out a running thread, which is being wound onto one of the bobbin holders, so that it forms a yarn package on the latter. A transfer device automatically carries out the transfer of the running thread from one bobbin to the other of the bobbin. Then when the yarn package is formed on this other bobbin, the running thread is automatically transferred back to the former bobbin. The thread transfer device of the above-mentioned patent uses an upper and a lower guide device and thread slide, each of which has an individually pneumatically actuated drive unit with cylinder and piston for its drive. The upper and lower guide devices are effective in the direction transverse to the thread slides, so that the upper and lower guide devices can position the thread for gripping by the thread slides, which each grip the running thread and this out of a cross guide device and towards a swing arm slide through a guide plate to pick it up. _

Despite such automatic thread transfer devices, however, there is a need for on-line automatic winding machines to simplify such a device and improve its operation by making such an automatic winding machine so adaptable that it can process an unlimited number of flexible materials .

The most important object of the present invention was therefore to provide a method and a device for the continuous winding of flexible material, the material being deflected from one revolving winding support to another winding support, so that the material can be wound up without interruption after it is in an uninterrupted operation at a substantially constant speed.

The device is said to be able to be used to wind up many types of flexible material, such as electrical lead wires, optical fiber material, flat ribbon-like cables, etc.

Furthermore, the device should either be fully automatic, requiring a minimum of attention on the part of the operator, or semi-automatic, with different, e.g. B. are dictated by the type of material to be wound up dictated activity can be performed.

Furthermore, such a winding downtime should be achievable, which leads to an increase in productivity, and the device should be so well adapted to a device that continuously delivers the material at a relatively constant speed that the winding can take place without interrupting the material supply.

Furthermore, the device should be controllable by microprocessors, which enables greater adaptability of the winding process and greater versatility in the type of winding that can be carried out by the device

In particular, the object of the present invention was to create an automatic winding device 5 which continuously transfers flexible material after the completion of a winding on a first winding carrier from the first winding carrier to a second winding carrier and then after completion of a winding the second winding carrier and removal of the material previously wound onto the first winding carrier is automatically transferred from the second winding carrier to the first winding carrier.

To solve the problems, the method according to claim 1 and the winding machine for performing the

15 Procedure according to claim 8.

Because of the property of being able to wind the flexible material on different spindles without interruption, the term on-line for the winding machine is

Winding machine used.

In an expedient further development, a central unit is programmed in such a way that the components of the on-line winding machine are reset to manual or automatic operation beforehand, so that these components assume 25 known predetermined positions, from which the workflow can either be carried out by Can be done manually or automatically. The central unit not only controls the movement of the spindles and the vertical and horizontal transfer arms, but also the thread guide and a gripping and separating device on the fixed end piece of the lower and the upper winding carrier.

In automatic operation, the flexible material is automatically transferred by a cooperative movement of the horizontal and vertical transfer arms, the flexible material being transferred from a wound winding carrier to an unwinded winding carrier and the material being separated from the wound package. Following a transfer of the flexible material, the end piece is removed from the wound winding carrier and the spindle having this winding carrier is moved towards the operating station so that the winding can be removed from the winding carrier. .

In manual mode, the vertical and horizontal transfer arms are deactivated and the material is transferred 45 by the operator, who also initiates the rotation of the spindles and their pivoting between their inner and outer positions.

The on-line winding machine is suitable for winding up material in any known winding form, including the so-called universal winding, which has a radial hole extending from the outside of the winding to the inner winding core, so that the wound up material is drawn off from the inside of the winding through the radial hole can.

The invention is explained in more detail below, for example, with reference to the accompanying drawing. Show it:

As can be seen in FIGS. 1 to 3 and in particular in FIG. 1, a main frame 20 has a side frame 22 attached to it which carries a vertical transfer arm support 24. The main frame 20 includes shelves 26, 28 and 30 for carrying various components of the on-line winder. In particular, each shelf 26, 28 contains a pair of rails 32 and 34, respectively, for supporting the drive device 36, 38 for the upper and lower spindles, comprising a drive motor and a gear. A sled-like horizontal transfer device 40 is suspended from the shelf 26 and contains spaced-apart guide rails 42 and 44, on which a horizontal transfer arm 46 is slidably arranged, the construction, operation and function of which will be described in more detail below.

An upper winder 48 is suitably mounted on a spindle shaft 49 and has a fixed end piece 50 which contains a separating and gripping device (which will be described in more detail below with reference to Fig. 17),

and a removable end piece 52, the function of which will be described in more detail with reference to that illustrated in FIG. 4. Likewise, a lower winding support 54 is arranged on a spindle shaft 55 and is equipped with a fixed end piece 58, which also contains a separating and gripping device, and with a removable end piece 56, which is similar to the removable end piece 52 of the upper winding support 48. The thread guide 60 (which is shown in more detail in Fig. 4) is arranged to move up and down between the upper and lower winding carriers 48, 54 in a direction parallel to the spindle shafts 49 and 55 in order to place flexible material on the upper or the lower, respectively Wind up the winding carrier 48.54. As can be seen in FIG. 1, the sled-type horizontal transfer arm 46 can move in and out with respect to the upper and lower winding carriers 48, 54.

A vertical transfer arm assembly 62 is mounted for vertical movement between an upper microswitch position sensor 64 and a lower microswitch position sensor 66, as shown in FIG. 1. Upper and lower shock absorbers 68, 70 are mounted on the vertical transfer arm support 24 to dampen the stopping of the vertical transfer arm assembly 62 in its upper and lower positions, respectively. The vertical transfer arm device 62 has two support parts 72 and 74 which extend at a distance parallel to one another, each of which carries a transfer arm 76 at its free end (only one of which is shown in FIG. 1 in order not to overload the drawing) ).

In the rear view of the main frame 20, as shown in Fig. 2, it can be seen that each spindle drive device 36 and 38 has a motor 75 and 77 and a pulley 78 and 80, respectively, which on the spindle drive shaft 49 and 55 is attached. The pulleys 78 and 80 are each driven by a drive belt 82 and 84, which rests on the drive shaft of the associated motor 75 and 77, respectively. In Fig. 2, the spindle drive devices 36 and 38 are shown with solid lines in their inner end position, in which the upper and the lower winding carrier 48, 54 are rotated for winding the material onto the winding carrier. In Fig. 2, the spindle drive devices 36 and 38 are also drawn with dashed lines in their outer end position, into which each spindle drive device can be moved on the upper or lower winding carrier after completion of a roll of flexible material, so that it can be operated by the operator to enable the material to be removed from the one winding support while the flexible material is continuously being wound onto the other winding support. It is understood that the spindle drive devices 36 and 38 are alternately positioned in an ON or OFF position according to a program (described in more detail below) and by means of suitable pistons, e.g. B. are driven pneumatically or hydraulically and are not shown in the drawing, since such elements are well known to the person skilled in the art to whom this invention is directed.

2 also shows the thread guide drive motor 86 and the thread guide cam gear 88, which is connected to the thread guide drive motor by means of pulleys, a drive belt 90 connecting the thread guide cam gear 88 to a gear 92, which in turn is connected by a drive belt 94 is connected to the thread guide drive motor 86. As is more clearly shown in Fig. 4, the thread guide 60 has a guide sleeve 96 through which the flexible material 98 is guided from a source (not shown) either to the upper or to the lower winding support in order to wind up the flexible material there . The flexible material 98 can be supplied via a memory which can be fed directly from one of the flexible materials, e.g. Wire cable, manufacturing machine system is fed. This enables the wire cable or other flexible material to be wound up immediately after manufacture. The purpose of storing the flexible material in a memory or accumulator is to compensate for the downtime of either the on-line winding machine or the manufacturing system, so that the material can be wound up continuously.

Finally, FIG. 2 also shows a solenoid and valve arrangement 101 which is attached to the shelf 30 of the main frame 20. Such solenoids and valves are used in the hydraulic or pneumatic control for moving the winding carriers in and out and the control for moving the horizontal transfer arms out and in.

Fig. 3 shows the position of the horizontal transfer arm 46 with respect to the upper and lower winding carriers 48, 54. This figure also shows a pneumatic or air cylinder 100 with piston 104, which in turn is attached to the removable end piece 52 of the upper winding support 48. By actuating the cylinder 100, the movable piston 104 is pulled in and the removable end piece 52 is pulled off the winding support 48. The upper wrap carrier 48 can then be moved backward (with reference to FIG. 3) so that the operator can remove the wound flexible material from the wrap carrier. The lower spindle 55 is assigned an identical cylinder 106 with piston 110, which piston is attached to the removable end piece 56 of the lower winding carrier 54, as shown in FIG. 3. As further shown in FIG. 3, the horizontal transfer arm 46 has two transfer fingers 112 and 114

whose function and operation is described in more detail below.

The position of the removable end piece 52 shown in dashed lines in FIG. 4 illustrates the mode of operation of the cylinder 100 when the removable end piece is removed from its holder on the upper winding carrier 48. The ON position of the removable end piece 52 is shown in solid lines in FIG. 4, in which ON position the removable end piece is pinned to the end of the upper winding support 48 so that flexible material can be wound thereon by the thread guide 60. As further shown in FIG. 4, the horizontal transfer arm 46 is spaced apart from guide rails 42, 44 (only one of which is shown) between an ON position sensed by a microswitch 118 and an OFF position sensed by a microswitch 120. Position can be moved back and forth. The horizontal transfer arm 46 in its OFF position is shown in FIG. 4 with dashed lines. As will be described in more detail below, the flexible material is transferred from the upper to the lower winding carrier and from the lower to the upper winding carrier by an interaction of the horizontal and vertical transfer arms. Figure 4 shows the relative positions of the horizontal transfer arm 46 and a link of the vertical transfer arm assembly 62 which they assume immediately prior to initiating a transfer operation.

FIG. 5 shows the vertical transfer arm assembly 62 in its lowermost position, in which it rests on the shock absorber 70 and in which the lower switch microswitch 66 is actuated to indicate that the vertical transfer arm assembly 62 is actually in operation is in the lowest position. This position of the vertical transfer arm means is used to position the support member 72 having the transfer finger 120 so that the transfer finger 120 grasps the flexible material at a point between the exit of the thread guide and the lower winding support 54 and the flexible material can be transferred from the lower winding support to the upper winding support 48 after the completion of a winding on the lower winding support 54. In the uppermost position of the vertical transfer arm device 62, in which the microswitch 64 which detects the upper end position is actuated in order to deliver a control signal to the control circuit arrangement (which will be described in more detail below), is the carrier part 74 equipped with a flexible transfer finger 122 in a position in which the section of the flexible material extending from the winding carrier 48 to the thread guide is gripped by the transfer finger, so that the flexible material can be transferred from the upper winding carrier 48 to the lower winding carrier 54. The function and mode of operation of the transfer fingers 120, 122 and their interaction with the spacing-apart transfer fingers 112, 114 of the horizontal transfer arm 46 are described in more detail below. Suffice it to say that with a suitable vertical movement of the vertical transfer arm device 62 and a suitable horizontal movement of the horizontal transfer arm 46, timed, the flexible material can be transferred from the upper winding carrier 48 to the lower winding carrier 54 and vice versa. Such a transfer process is carried out in connection with a separating and gripping process, which is described in more detail below with reference to the representation in FIG. 17.

The transfer of flexible material from the lower winding carrier 54 to the upper winding carrier 48 is illustrated in FIGS. 6-9. As can be seen in FIG. 6, after the completion of a roll of flexible material on the lower roll carrier 54, the thread guide is pushed to its innermost position next to the horizontal transfer arm 46. The lower bobbin 54 is rotated two turns to ensure that the flexible material abuts the inner end 58 (FIG. 6). Then, the lower horizontal transfer finger 114 of the horizontal 5 transfer arm 46 is moved outward from an inner position so that it grips the flexible material 98. Moving the horizontal transfer arm 46 further out causes the flexible material to be brought into a position shown in FIG. 7, in which the flexible material 98 extends over the vertical transfer finger 120 of the upper carrier part 72. During the movement of the horizontal transfer arm 46 from the position shown in FIG. 6 to the position shown in FIG. 7, the horizontal transfer finger 114 comes into engagement with the vertical transfer finger 120, 15, which is ventable, so that the flexible material 98 and the horizontal transfer finger 114 can reach the position shown in FIG. 7. Following this, as illustrated in FIG. 8, the upper support part 72 is moved vertically upward, so that the vertical transfer finger 120 grips the flexible material 98 to move it upwards. Some time after the upper support member 72 is moved vertically, the horizontal transfer arm 46 is moved inward so that the flexible material 98 is released from the horizontal transfer finger 114 and can be moved upwards to the upper winding support 48. A further upward movement of the carrier part 72 causes the flexible material 98 to bear against the upper winding carrier 48 at a point where it meets the fixed end piece 50, in which a separating and gripping device is arranged. The flexible material is gripped by 30 of the gripping device and by actuating the separating device the flexible material 98 is separated, as is shown in FIG. 9 is illustrated.

Before the flexible material 98 was transferred from the lower winding carrier 54 to the upper winding carrier 48, the 35 spindle drive for the lower winding carrier 54 was stopped and the position of the separating device on the winding carrier 48 is felt and, if necessary, the upper winding carrier 48 is adjusted such that the separating and gripping device is in a position for receiving the flexible material. 40 The transfer of flexible material from a fully wound upper winder 48 to the lower winder 54 is illustrated in FIGS. 10-13. As shown in FIG. 10, after the completion of a flexible material roll on the upper roll carrier 48, the horizontal transfer arm 45 is caused to move outward so that the upper horizontal transfer finger 112 grips the flexible material 98 and the horizontal transfer finger 112 takes the vertical transfer finger 122 of the lower support part 74 with it during its outward movement. The vertical transfer finger 122 is also flexible so that it is pushed back by the horizontal transfer finger 112 engaged with it to slide over the horizontal transfer finger 112 and the flexible material 98 gripped by it over the vertical transfer finger 122 and to reach the position shown in FIG. 11. The simultaneous continuation of the outward movement of the horizontal transfer arm 46 and a lowering downward movement of the lower support part 74 of the vertical transfer arm device causes the flexible material 98 to engage the upper thus horizontal transfer finger 112 and the vertical transfer finger 122 as shown in FIG. 11.

As illustrated in FIG. 12, the horizontal transfer arm 46 is moved inward so that the horizontal transfer finger 112 releases the flexible material 98 and causes the 65 downward movement of the lower support member 74 with the vertical transfer finger 122, that the flexible material 98 engages with the separating and gripping device arranged in the end piece 58 of the lower winding carrier 54

is coming. The flexible material is gripped by the gripping device and cut by the separating device so that the flexible material is now held on the lower winding carrier 54 and moving the horizontal transfer arm 46 outward causes the cut material to be wound around the upper winding carrier 48 and out the area of the lower winding carrier 54, so that when the flexible material is wound up by rotating the lower winding carrier 54, the free end of the flexible material on the upper winding carrier 48 does not become confused with the flexible material to be wound on the lower winding carrier 54.

Fig. 14 shows how the vertical transfer finger 122 is disposed in the lower support member 74 so that it can be reset when it engages with the transfer of flexible material from one spindle to another when a horizontal transfer finger is moved outward . As can be seen in FIG. 14, the vertical transfer finger 122 is fastened on a rotatable shaft 130, which increases the tension of a spring 132 in such a way that after the force of the fingers pivoting the flexible finger 122 ceases to apply, it returns to its 14 sets ordinary working position shown.

15 illustrates the corresponding spatial displacement of the lower and upper horizontal transfer fingers 112 and 114, which are installed in the same manner as described above for the vertical transfer finger 122 and shown in FIG. 14, so that the horizontal transfer fingers 112 and 114 during the inward movement of the horizontal transfer arm 46 can be reset by engagement with the vertical transfer fingers. It should also be noted that the vertical transfer fingers are retractable upon the horizontal transfer arm 46 moving outwardly by engagement with the horizontal transfer fingers.

16 is a partial view illustrating how the horizontal transfer finger 112 is attached to a rotatable shaft 140 and the spring 142 is tensioned by pivoting the horizontal transfer finger 112 counterclockwise about its axis 144.

Fig. 17 is a z. T. cut view of a winding carrier, which illustrates the structure and operation of the separating and gripping device, which is arranged in the fixed end piece 50 of the winding carrier. As shown in Fig. 17, a power cylinder 150 moves a flange 152 engaged between lugs 154, 156 of the piston 158. Moving the flange 152 inward causes an arm 160 to also move inward, which arm engages the flexible material. Moving the piston 158 further causes the separating device to cut the flexible material still held by the gripping device. After the spindle has been rotated a few revolutions so that the flexible material is held on the winding carrier 48 by its own turns, the working cylinder is released so that the gripping device is also released.

The separating and gripping device can be constructed such that the gripping device remains in the gripping position and the separating device is reset. If the gripping device has an edge that penetrates somewhat into the material, the material (if it is an insulated wire) can remain in electrical contact with the winding device. This is important if certain checks have to be carried out while being rolled up.

Although not shown in detail, the material wound on a winding support is removed therefrom by removing the removable end piece, such as the removable end piece 52 from the winding support 48, and thus the winding support 48 and the associated spindle drive device 36 on the guide rails 32 (Fig. 1) can be moved outwards. If the winding body 48 has been completely removed from its operating position, the operator 664 349 can then

End the device with which the middle part of the winding support 48 contracts and thereby the flexible material on it is released for easy removal. Such a pulling device is well known to the person skilled in the art, so that it does not need to be described here in more detail for the implementation of the invention. A peelable wrap carrier is disclosed in U.S. Patent Application Serial No. 242130, filed March 9, 1981 by the same applicant as the present invention. In the same way, the flexible material wound on the lower winding carrier 54 is removed by removing the removable end piece 56 from the winding carrier and moving the winding carrier 54 and the spindle drive device 38 associated therewith.

The control of the various components of the on-line winding machine for transferring the material from an upper winding carrier to a lower winding carrier and from the lower winding carrier to the upper winding carrier is illustrated in FIGS. 19a and 19b and in FIGS. 20a and 20b.

The following describes the resetting of the on-line winding machine, whatever is done before manual or automatic operation of the machine. The reset is under the control of a central processing unit (CPU) which is part of the control circuitry shown in FIG. 18. In the control functions shown in FIG. 18, after applying the operating voltage and after releasing the CPU reset line, the CPU uses the cellar memory 180, which stores the necessary information in the CPU. The CPU turns off all of the control valves in the on-line winder, as indicated by control function 181.

These valves are e.g. Air or pneumatic solenoid valves that control the movement of the various components within the winding device, such as the end pieces, the spindle tables, the separators, the vertical and horizontal carriages, etc. The CPU then checks whether the valves are actually turned, what by sensor 182 is sensed.

It should be noted that considerable interference voltages can occur when the operating voltage is switched on, so that the control function 181 was not designed to turn off all the solenoid valves due to malfunctions. Therefore, if not all of the valves have been turned off, the control function 181 is repeated as many times as is indicated in FIG. 18. It is necessary that all control valves are turned off in order to exclude damage from an otherwise resulting movement of the various components of the online winding device and the possibility of such components colliding with one another.

Control function 183 stops all motors and turns off all indicators. The INTERRUPT is set to let the CPU run again at a special address. The aforementioned steps in the reset process are necessary so that the device is not turned on in a random state. The reset functions only take a few microseconds, so the components of the online winding machine do not have time to move before the CPU shuts down the various motors and valves. The reset function continues with a control function 184 in which the valves for raising the upper end piece, the upper separator, the lower end piece and the lower separator as well as for adjusting the cylinder for the horizontal arm are all energized. The upper end position sensor is controlled and when the upper end position is in the off position sensed by sensor 185, the lower end position sensor is controlled by sensor 186, the upper spindle adjustment sensor controlled by the sensor 187 and if the upper spindle is not in the on position, the control function 188 will move it to the off position at the operator's place 7

sent it. Then the on sensor of the lower spindle is checked and if the lower spindle is not in the on position, it is sent by the control function 190 to the off position at the operator's place. Then, in the reset mode, there is a time delay of approximately two seconds duration provided by the CPU in the timer function 191, and after this interval the upper and lower spindle tables or carriages are inserted into the control function 192 On position moves. The positions of the upper and lower spindles are checked by sensors 193 and 194, respectively.

The above work processes are necessary because the actual positions of the upper and lower spindles are not recorded by the CPU, unless the lower and / or upper spindles are in the on position and this position has actually been determined is. The above-mentioned work processes only bring the various components of the on-line winding machine, such as the upper and lower end piece and the upper and lower spindle, into a known position. Each spindle table or carriage encounters a shock absorber at the end of its movement. The shock absorber in the off position (at the operator's place) is a spring shock absorber. The shock absorber in the on position (the position close to the thread guide), however, is an air suspension. Since the operating state of the shock absorber at the on position is not known, the spindle table or carriage must be sent to the off position if it is to be recognized that it is not in the on position. The time interval of two seconds specified by the control function 191 guarantees that the shock absorbers are set to the off position at the on position.

Continuing with the reset mode, as shown in Fig. 18, a second, one and a half second time delay is then introduced by a timer function 195 so that the spindle tables or carriages are in their on positions after striking the aforementioned shock absorbers - can swing. The CPU then determines the operating mode provided for the online winding machine, automatically or manually, by sensing the switching state of the manual / automatic switch 196.

When automatic operation has been selected, the control function 197 brings the upper and lower end pieces into the on position and the successful completion of the corresponding operations is controlled by sensors 198 and 199. Next, the control arm 200 places the vertical arm cylinder in the DOWN position and the adjustment of the vertical arm cylinder is controlled by sensing the sensor 201. The horizontal arm cylinder is then set to the OFF position by the control function 202 and the position of the horizontal transfer arm is checked by the horizontal arm OFF sensor designated by the reference numeral 203 in the diagram in FIG. 18. If it is determined that the horizontal transfer arm is actually in the off position, the CPU waits until the RUN key is pressed and the automatic winding in direct operation is started, as described below with reference to FIG 20a, 20b described control functions is described in more detail.

When the operator has selected manual operation, the upper and lower end pieces are set to the on position by the control function 204, as shown in FIG. 18. The control function 205 removes the drive energy from the horizontal arm cylinder and the CPU then waits until the DOWN (RUN) key is pressed, which is represented by the control function 206, and manual operation is started in the online winding machine .

In manual operation of the online winding machine, a sensor 207 checks the position of the cylinder of the vertical transfer device.

direction on the vertical transfer arm support 24. This sensor 207 corresponds to the microswitch 64 shown in FIG. 1. The operator previously placed the flexible material on the lower winding carrier 54 of the winding machine 5 by hand. When the upper cylinder is in the correct position (which is indicated by the YES output of sensor 207), the lower cylinder is switched on by the control function 208, so that the lower spindle drive motor after the wire has been laid on the by hand The winding operator starts up in tactile mode by the operator to wind up the wire for holding onto the lower winding carrier 54. In the event of,

that the upper cylinder is not in the appropriate position, the control function switches off the digital-to-analog converter that starts the engine. Pressing the Start-15 button BN by the operator switches the digital-to-analog converter off via the function 209 and the upper removable end piece 52 is moved outwards by the function 210 away from the winding carrier 48. A suitable sensor 212 (which is not shown in the drawing to avoid overloading) then checks the position of the removable end piece. When the detachable end 52 of the upper winder 48 is actually in its outermost position, the control function 214 moves the upper winder 48 outward so that the material wound thereon can be removed by the operator. According to the program, the upper winding carrier 48 is then moved inwards again into the winding position, which is checked by a suitable sensor indicated by block 216 in FIG. 19a. Then a timer function is set for about two seconds to prevent the end of the flexible material from becoming entangled in the lower winding carrier as soon as it starts winding. Such a timer function is represented by block 218. After a period of approximately two seconds, the lower winding carrier 54 is caused to wind up by the control function 220, which starts the spindle drive motor, and the control device is caused to insert a five-second time interval, which is indicated by the control function 224 in order to give the operator sufficient time 40 to release the start button actuated at control function 209 before the upper spindle drive motor was switched off. The controller then performs a check to see that the starter button is pressed and the controller then operates to set the upper spindle to the on position by the control function 226 in FIG. 45, which is the winding position for the spindle. Position is. The on position of the spindle is checked by suitable sensors, indicated by block 228, and the control device then uses a five-second time interval as specified by the control function 230 to ensure that the spindle carriage does not bounce. The program continues with the subsequent insertion of the removable end piece 52 of the upper winding carrier 48 into its winding position, in which it is connected to the winding carrier. This work is initiated by the control function block 232 and the position of the removable end piece of the upper winding support 48 is checked by the sensor function 234. The control device then controls the length counter and when the appropriate amount of flexible material is wound onto the lower winding carrier 54 60 and checked by the sensor 236, the rotation of the lower winding carrier is stopped by the control function 238.

The operator then cuts the flexible material by hand and attaches the free end to the upper wrap carrier. The operator then presses the BN button to push the upper winding support and to ensure that sufficient material has been wound onto the winding support. If the starter button BN for the rewind carrier return

is pressed, the D / A converter is switched off by the control function 240 in order to start the upper winding support for winding up by the control function 242. In the event that the starter button BN is not pressed for the winding carrier return, the machine remains in the control loop between the control functions 238 and 240.

During the winding up on the upper winding support, the lower end piece is pulled off by the control function 244 and the correct completion of this process is monitored by the sensor function 246. The lower spindle can now be extended to the operator station using control function 248. A five-second time interval is then inserted by the control function 250 in order to give the operator time to release the starter button BN pressed in front of the control function 240 for the winding carrier. By pressing the starter button BN for the winding support, the empty lower spindle is now returned to the on position by the control function 252 and the correct completion of this process is checked by the sensor 254. The timer function 256 allows a time delay of five seconds to ensure that the lower spindle carriage does not bounce. The lower end piece is then brought to the lower winding carrier by the control function 258 and this process is monitored by the sensor 260. The length counter for the winding support on which the material is wound is then controlled by the control function 262 and as soon as the correct length is reached, the upper spindle drive is stopped by the control function 264. The program then moves to the original starting point.

In the following, the automatic operation of the on-line winding machine is described on the basis of the control functions shown in FIGS. 20a and 20b. The CPU turns on the lower spindle through the program function 310 for winding.

The CPU switches on a solenoid valve to move the upper movable end piece outwards (away from the upper winding carrier). The switch 312 closes when the upper end piece is in the off position, i. H. is withdrawn from the winding support. The position of the upper end piece is controlled by the sensor 314 and the program continues with the adjustment of the upper winding carrier into the off position by the program function 316. The program then sets a waiting time of three and a half seconds, which is initiated by the timer 318 . It should be noted that all time functions are provided by the software and executed by the CPU. The subsequent program introduction then continues with the positioning of the lower separating device in the off position by the program function 320.

It should also be noted that function 310 has two entry points, one of which has been described above. The other entry point comes from the end of the program. Control functions 318 and 320 are required because the lower separator was set to the on position by the CPU at function 438. The first program run did not make function 440 functional. Functions 318 and 320 are not necessary for the first run, but are required every time.

The program then checks the spindle reset button 322 and the program proceeds to set the upper winder to the on position by the program function 324. The position of the upper winder is sensed by the sensor 326 and then the program is run by the timer 328 a waiting time of about two and a half seconds. The program continues to set the on-line winder by positioning the upper end piece in the on position via program function 330 and this position is sensed by sensor 332. The operating program then continues with the positioning of the upper separator by subroutine 334 and the length counter

664 349

controlled by the sensor 336, the lower spindle drive motor being switched off by the program function 338 when the length counter contacts are open. Now the function 340 is used to adjust the horizontal cylinder inwards (towards the thread guide). Next, the thread guide eccentric is set using function 342. The position of the horizontal cylinder is sensed by sensor 344 to be sure that it is not in the off position. Then the lower spindle drive motor is switched on by the program function 346 in order to start winding material from the thread guide onto the lower winding support so that it lies against the inside of the end piece. The program then introduces a waiting period of one and a half seconds via the timer function 348 and the lower spindle drive motor is switched off by the function 350. The horizontal cylinder is then placed in the outer position by the program function 352 and the position of the horizontal cylinder is checked by the sensor 354. The vertical cylinder is then brought into the upper position by the program function 356 and the position of this cylinder is controlled by the sensor 358.

Note that the vertical cylinder is sent UP by control function 356, but the program samples whether the vertical transfer device is still DOWN. Time is required in each control device for the controlled components to function. Function 358 ensures that the vertical transfer device is not located DOWN. However, it is still not known whether it is UP. All that is known is that she is on her way. The time interval between the energization of the valve controlled by the function 356 and the opening of the switch 358 is counted by the counter 359. This time interval is required to prevent the vertical and horizontal transfer fingers from colliding with each other when their paths intersect.

The program proceeds with the setting of the horizontal arm in the on position by function 360. The position of the vertical cylinder is then sensed by sensor 362 and when it is in the upper position, the program continues with Positioning the spindle by program function 364. This is a check to be sure that the separator has not been adjusted during the transfer process just described. The program then proceeds to set the upper separator to the on position by program function 366. The position of the upper separator is then checked by sensor 368 and when the separator is in the on position, the program proceeds to turn on the lower spindle drive motor with a digital-to-analog converter (which is described in more detail below with reference to FIG. 21). This is done via program function 370. The program then introduces a waiting period of one and a half seconds, which is determined by the timer 372. This is necessary in order to maintain sufficient tension on the wound material so that it breaks free from the separating device and the upper winding support. The lower spindle drive motor is then switched off by program function 374. Then the upper spindle drive motor is switched on by the program function 376 and the upper spindle winds up material. According to the program, the lower end piece is then placed in the off position and this position of the lower end piece is then checked by the sensor 380. Then the lower spindle is placed in the off position so that the wound material can be removed by the operator, and the program sets a four and a half second waiting time via the timer 384. The upper separating device is then moved into the exit by the program function 386.

Position and then the spindle return button is checked by sensor 388. Subsequently, the lower spindle is set to the on position by the program function 390 and this position of the lower spindle is controlled by the sensor 392. The program then introduces a two and a half second wait time through timer 394. According to the program, the lower end piece is then put into the on position by the program function 396 and the position of the lower end piece is checked by the sensor 398. The spindle is then positioned by the program function 400 and the length counter is checked by the sensor 402 (the same as sensor 336). The upper spindle drive motor is then switched off by the program function 406. The thread guide eccentric is set by the program function 406 and the upper spindle drive motor is then switched on by the digital-to-analog converter (which is described in greater detail below with reference to FIG. 21) via the program function 408. The program then introduces a one and a half second wait time using timer 410 and the upper spindle drive motor is turned off by program function 412. Then the horizontal cylinder is set to the off position by the program function 414 and the position of the horizontal cylinder is checked by the sensor 416. If the sensor indicates that the horizontal cylinder is actually in the off position, the vertical cylinder is placed in the DOWN position by the program function 418 and this position of the vertical cylinder is checked by the microswitch sensor 420. The program then proceeds with a one and a half second wait time (for the same purpose as described above) determined by the timer 422. The program then proceeds to place the horizontal cylinder in the on position via program function 424, whereupon this position of the horizontal cylinder is controlled by sensor 426 so that the program continues when that sensor indicates that the horizontal cylinder is actually in the on position. This on position for the horizontal cylinder is approximately in the middle of the path from the thread guide to the off position of the horizontal cylinder. The horizontal cylinder is then turned off by function 428 and the position of the vertical cylinder is then checked by sensor 430 to see if it is in the DOWN position. When the sensor indicates that the vertical cylinder is actually in the DOWN position, the horizontal cylinder is placed in the off position by program function 432 and the position of the horizontal cylinder is controlled by sensor 434. By placing the horizontal cylinder in the off position for a second time, it prevents the hanging material from becoming tangled in the lower winding carrier after cutting. If the sensor 434 indicates that the horizontal cylinder is in the off position, the spindle position is checked by function 436 and the lower separator is driven by function 438 to the on position to cut the material, and if the Sensor 440 indicates that the material has been cut, the program introduces a waiting time of one and a half seconds, which is set by timer 442. The program then proceeds to function block 310 to turn on the lower spindle to wind up the material and the entire program is repeated so that the material is transferred to the upper and lower winding carriers with appropriate transfer of the material after each completed winding on one Winding carrier is wound.

Fig. 21 shows a block diagram of the controller for the on-line winding machine. All control functions are provided by a central processing unit (CPU) 500, which contains a clock, a ROM 501 and a RAM 503, the

10th

Central unit receives 500 operator inputs from the various limit switches, the positions of the vertical cylinder and the horizontal cylinder, the spindle tables, separating devices, the start buttons for the reel-holder return, 5 the length counter, etc. and the various solenoid valves for positioning Detect the horizontal cylinder, vertical cylinder, spindle tables, separators, end pieces, etc. The CPU 500 also receives messages about the positions of the upper and lower spindles as well as about the xo positions of the thread guide eccentric and outputs suitable output signals to the eccentric digital / analog converter and the counting circuit 502. The CPU also receives an interrupt signal. The CPU 500 reads the eccentric position encoder (port) and the spindle position encoder (port) (depending on 15 which spindle is being wound). The toothed wheel settings and the INTERRUPT signal determine where the thread guide eccentric should be. The CPU then writes to the eccentric digital / analog converter. The output signal will be positive if the actual eccentric position is below the calculated eccentric position, negative if the actual value is above the calculated position value, and be zero if the actual value and the calculated value for the eccentric position are identical are. The CPU 500 also provides input to the spindle digital to analog converter 504. 25 The spindle digital to analog converter 504 provides input to the spindle select multiplexer 506 which controls the upper and lower spindle drives 508 and 510, respectively. The main speed for the upper and lower spindle drive is set by means of a potentiometer 512 over a linear 3 ° voltage increase.

The upper and lower spindle drive motors are each assigned a two-channel encoder, each of which has a signal stabilization circuit, as is well known to those skilled in the art. In the upper spindle 35 drive motor 514, the encoder 516 has a two-channel output, namely channels A and B with a 90 ° phase shift between the signals on channels A and B. On the output side, channels A and B of encoder 516 are at one Up / down counter 518 connected. A Hall sensor device 520 serves to index the rotation of the upper spindle drive motor 514 and its output signal divided by 2 is applied to the up / down counter 518. The count of the up / down counter 518 indicates the position in hundreds, tens and ones of angular degrees. This provides a position (port) for the 45 upper spindle. An output of the up / down counter 518 is also connected to an interrupt multiplexer 522.

In the same way, an encoder 526 is assigned to the lower spindle drive motor 524, the dual output channels 50 A and B of which are connected to inputs of the up / down counter 528. The Hall sensor device 530 supplies an input signal to the up / down counter 528 via a halving circuit 532. The count of the up / down counter 528 indicates the position of the spindle shaft in hundreds, tens and ones of position units. An output of the up / down counter 528 is also connected to an interrupt multiplexer 522, the output of which outputs a maskable INTERRUPT signal 536 to the CPU 500.

The output of encoder 516 on the upper spindle drive motor and the output of encoder 526 on the lower spindle drive motor are connected to the input of a tach selector and frequency / voltage converter circuit 540, the output of which is connected to a speed error circuit 542 connected. The speed error circuit also receives a position error signal from the eccentric digital to analog converter 502.

The thread guide motor 550 also has a two-channel encoder 552, the output channels A and B of which are connected to an up /
