The other end of the lever. 10 is arranged on an axis 12 which is supported in bearings (not shown) provided on both sides of the frame, during which it is approximately in the middle of the lever lying part via a pin 15 with a rod 14 of a piston actuated by pressure medium in a cylinder 15 is coupled. In this way, the auxiliary roller 9 can the axis 12 is pivoted by the action of the cylinder 13 will.

Between the auxiliary roller 9 and the grooved Wiokel roller 1 'is a take-off roller 16 rotatable on a shaft arranged at the end of a lever 17 which has a bent over Forms an extension part of the lever 10, the removal roller 16 having the same width as the auxiliary roller 9, however has a smaller diameter than this. Die.Abnahmewalze 16 is through the action of the cylinder 13 together with of the auxiliary roller 9 about the axis 12 over a given arc swiveled.

Above the grooved Wiokel rollers 1 and 1 * are a Coil magazine 18, a coil guide 19 and a coil conveyor device 20 are arranged. At the outlet 21 of the inclined Spool magazine 18 1st at 21 * a stop 22 together with a lever 32 pivotably arranged, and the front end of the outlet is supported by an upward part 19 * the coil guide 19 is formed. At a lower outlet 23 the bobbin guide 19 is also a stop 24 at 30 *

909828/0813

pivotally arranged. The base of the bobbin conveyor 20 is together with a lever 27 by means of a shaft 26 pivotably mounted in bearings 25.

The oscillating movement of the coil conveyor device 20 is connected to the stop 24 via an interposed Link mechanism 27, 28, 29 and with the stop 22 over an intermediate link mechanism 30, 31 * 32 coupled. A lever 33 'which the bent and itself Forms over the shaft 26 extending part of the lever 27 is at its end by means of a pin 35 with the one arm of an angle lever 3 ^ connected, the other Arm by means of a pin 38 with a piston rod 37 of a is connected by pressure medium actuated piston in a cylinder 36, the axis of the angle lever 3 ^ in Bearings 39 is supported. As a result of the operation of the cylinder 36, the coil conveyor device 20 can thus be pivoted, the action of the cylinder 36 via the two mentioned Link mechanisms is also transmitted to the stops 22 and 24.

In Fig. 2B a modified embodiment of this coil feeder is shown. Here, by raising and lowering a piston rod 81 of a cylinder 80 actuated by pressure medium, the stop 22 is opened and closed via the link mechanism 30, 31 t 32, the lever 30 of which ^{rotates about an axis 30 f} , about the coil conveyor device 20 immediately before it swings a new

309828/0813

Coil feeding (hereinafter referred to as "just before swinging" feeding method) -.

The coil feeder 20 has an arcuate shape and its end is as in Pig. 4, bent over to form a reel stop 20 *, at the end of which a curved plate 40 is articulated by means of a pin 41, a helical spring 42 being wound around the pin 41, which allows the plate 40 to be opened and closed via an arc , which allows a coil P .. between the stop 20 ^! of the bobbin conveyor 20 and the curved plate 40.

As can be seen from Fig. 5, the upper ends of the rack ^{arms 2, 2 1 are provided} with shafts 45 and 43 ', respectively, which can be displaced at right angles to the arms, and on these shafts 43, 43 * there are winding disks 45 and 43' respectively. 45 * arranged rotatably, which have mutually facing hub projections 44 and 44 *. These projections 44, 44 * are beveled and can engage with correspondingly beveled inner edges at the ends of tubular coils P. When the shafts 43, 43 * are moved inwards, ie “towards one another, the bobbin is clamped ^{between the winding disks 45, 45 1.}

At the side facing away from the winding disks 45, 45 ¹ ends of the shafts 43, 43 ¹ are in cylinders 48 and 49 arranged pistons 46 and 47 are provided. The diameter of the piston 46 and the inner diameter of the cylinder 48 are

909828/0813

somewhat larger than the diameter of the piston 47 or the inner diameter of the cylinder 49. Furthermore, the inner diameter of the cylinder 48 is made somewhat smaller in the vicinity of the arm 2 by forming a step 50, and this somewhat smaller diameter corresponds to the diameter of the smaller cylinder 49 match. In the middle of the outer ends 51 and 52 of the cylinders 48, 49 protruding side pieces 53 and 54 are attached, which are provided with ball-bearing rollers 55 and 55 *, which can roll ^{on the inside of guide rails 56 and 56 1, respectively,} which are arranged on the frame protruding outwards.

As shown in Figs. 1 and 6, there is in front of the grooved winding roller 1 (viewed in the direction from which the Wioklung is fed) and above it a roller 57 is arranged, which is in pressure contact with the grooved Winding roller 1 is to rotate together with this. A thread guide plate 58 is provided which against the Bottom of the roller 57 is inclined, and above this guide plate 58 is a clamp plate 60 together with a Lever 66 pivotably mounted on a transverse shaft 59, the lower end 61 of the clamping plate 60 being arranged in this way is to be brought into contact with or withdrawn from the full width of the top surface of plate 58 can be. At the lower end of the clamping plate 60 cooperating with the guide plate 58 is an additional plate 62 fastened, which are made of a material with great

Ö09828 / 0813

Exercise coefficients, such as rubber is made.

On a arranged under the thread guide plate 58 and parallel to the shaft 59 shaft 6j5 are arms 64 provided with bent ends together with a Hebei 67 pivotally supported. Between the ends of the arms 64 a pinch roller 65 is rotatably supported, which can be brought into contact with the front side of the roller 57 or withdrawn from it. The pinch roller 65 is rotated by frictional contact with the roller 57. Because the above-mentioned levers 66, 67 are coupled to a connecting rod 68 are, the clamp plate 60 and the arms 64 can move cooperatively together. Furthermore, the clamping plate 60, the lever 66, the arms 64 and the lever 67 are designed so that they are interconnected elements around the Shafts 59 and 65 can be swiveled.

Furthermore, as shown in FIG. 1, a lever 69, one end of which is connected to a piston rod 71 of a cylinder 70, is pivotably arranged on the shaft 59, which is rigid with respect to the lever 66 and the clamping plate 6O 1st, which is actuated by compressed air to transmit the action of its piston to the clamping plate 60 and to the arms 64 via the link mechanism described above. A Winding thread L is fed by two calender rollers 72 and 72 »the are arranged one above the other, delivered to the top of the plate 58 and then runs between the pinch roller 65 and the roller 57 hinduoh to roll on the between the vetch!

009820/0813

1 and 1 * arranged coil P to be wound up.

The electrical circuit for operating the machine described above is shown in Fig. 8a. Ls-1 to Ls-4 are momentary limit switches, and Ms is a microswitch. R ₁ and Rg are auxiliary relays whose contacts R ^r .. and R * _{2 are} closed when the relays are working, while contact R '^, which ^{acts opposite to contact R 1} ^, is closed when the auxiliary relay R ₁ is not aroused. T ₁ is a delay relay whose contact T ^l ₁ remains closed when the delay relay T _{1 is} not energized. MV ₁ to MVh are solenoid valves corresponding to those shown in FIG. 1. X is a warning signal, S ₁ and Sp are manual switches and P, is a push button.

The operation of the combination described above is with reference to the relationship between the electrically operating Parts and the parts that work with pressure medium:

When the winding thread L is wound onto the bobbin P, the pressure medium acts in the direction of the solenoid valves MV ₁ to MV ₂ , indicated in FIG. 1 by the upward arrows. In other words, since the pressure in the chamber A acts in the cylinder 5, the rack arms 2, 2 * are moved downwards via the toothing 7, the pinions 8 and 4 and the toothing 3. As a result, the bobbin P is in frictional contact with the winding rollers 1, 1 ^T

909828/081 3

presses, which rotate in the direction indicated by the arrow s and wind the winding thread L. On the other hand, since air pressure is ^{supplied to the chambers A 1} and A ″ of the cylinders 48 and 49 of the rack arms 2, 2 * (FIG. 5), the bobbin P is clamped between the winding disks 45 and 45 * the pressure medium from above acts, the auxiliary roller 9 and the take-off roller can be pivoted away 16 from the winding roller 1 ^1, while the air pressure acts in the cylinder 36 from below, whereby the coil transport device is held in its raised position 20, wherein they both be inserted as the next The bobbin P ₁ and the bobbin Pp to be inserted after the winding of the bobbin P _{1 are held} by the stop 22 at the end of the bobbin magazine 18. On the other hand, since the pressure medium acts in the cylinder 70 from above, the pinch roller 65 contacts the roller 57 and thus rotates that it facilitates the migration of the winding thread L while the clamping plate 60 is withdrawn from the guide plate 58.

When the winding thread has been wound onto the bobbin to the desired extent, the limit switch Ls-1 works for a short time by means of a sensing mechanism (not shown) to actuate the relay R ^ and to close the contact R * ... As this results in the circuit of the solenoid valve MV. closed is, the direction of flow of the pressure medium is reversed through the solenoid valve MV ^. Now there is the pressure medium in the chamber B of the cylinder 5 becomes effective

909828/0813

the rack socket 2, 2 * is raised over the toothing 7, the pinions 8 and 4 and the toothing 3. Although the pressure medium also ^{acts in chambers B 1} and B ^w of cylinders 48 and 49 at the same time, the pressure in cylinders 48 and 49 * acts somewhat in terms of time since the capacity of these cylinders is considerably smaller than that of cylinder 5 before the upward movement of the rack ^{arms 2, 2 f} , in order to move the shafts 4j, 43 * outwards, whereby the winder shafts 45, 45 * are opened to release their clamping grip on the reel P and the reel above the rollers 1, 1 * to release. Since the contact R ¹ ^ is still closed, the solenoid valve MVj. Also works, whereby the effect of the pressure medium in the cylinder 1J is reversed. The piston rod 14 is thus pushed upwards, and the auxiliary roller 9 and the take-off roller 16 are pivoted against the side of the winding roller 1 * into a position in which they can receive the full winding L *.

In the outlet 21 of the inclined coil magazine 18 arranged above the grooved Wiokel rollers 1, 1 ¹ , the end 22 * of the stop 22 is in alignment with the bottom of the coil magazine, so that the stop together with the upwardly directed part 19 ^{1 of} the coil guide 19 the Coil P ₂ stops. On the other hand, the bobbin conveying device 20 holds the next bobbin P _{1 to} be fed by means of its bent part 20 * and the bent plate 40. Since the upper surface of the bobbin guide 19 was previously moistened, the outer

909828/0813

re circumference of the bobbins when overflowing the guide moistened ' tet.

When the rack arms 2, 2 ^{1 are} raised and have reached a point near their position of maximum upward movement and the limit ^{switch Ls-2 is briefly actuated by means of 1 of} a suitable filling device (not shown), the relay R _{2 works} to its contact R ¹ 2 to close, whereby the _{circuit containing the solenoid valve MV 2} is closed. It follows that the solenoid valve MV ₂ works to reverse the pressure medium acting in the cylinder 36. Thus, the piston rod 37 moves downwards, and the Spulenfördervorriohtung 20 is pivoted over the angle lever 3 ^ and the lever 33 in the direction indicated by the arrow u in Fig. 1, so that while they are the full Wioklung L ₁ from the top the winding rollers 1, 1 * ejects to the side on which the take-off roller 16 and the auxiliary roller 9 are arranged, conveys the new reel P ₁ carried by its end to a point (Fig. 2A) which corresponds to the position of the axis of the Wiokel disks 45, 45 * coincides when the rack arms 2, 2 * recover their position of highest lifting. At this point in time , the full winding L _{1 has reached} a position in which the winding of the dispensed winding thread is continued, since the auxiliary roller 9 is driven at the same peripheral speed as the grooved winding rollers 1, 1 ^f .

Q09Ö28 / 0813

Since the base of the coil spring device 20 is pivotably mounted on the shaft 26 together with the end of the lever 27, it can move together with the link mechanism 27, 28, 29, which contains the pivot axes 26 and 30 ¹ , and with the link mechanism 30, 31 , 32, which contains the pivot axes 30 * and 21 ', rotate. Therefore, the stopper 24 and the stopper 22 are rotated when the bobbin feeder 20 oscillates. If the stop 22 is directed downwards due to such a rotation, the bobbin P ₂ can fall into the bobbin guide I9. At the same time, the end 22 ″ of the stop 22 prevents the next bobbin P 'from' the magazine 18 falling into the bobbin guide 19. On the other hand, since the stop 24 is rotated such that its tip is in alignment with the bottom of the bobbin guide 19 _{he stopped the bobbin P 2} that had run down in the bobbin guide 19 and prevented it from falling further (Fig. 2A).

When the rack arms 2, 2 * reach the point of their highest lifting, the bobbin conveyor 20 is pivoted to complete the ejection of the full winding in the direction indicated by the arrow t, and a new bobbin P ₁ is brought into a position which coincides with the axis of the winding disks 45, 45 *, while the limit switch Ls-3 is brought into position No by means of a filling device (not shown). When the border

909828/081 3

switch Ls-J is switched over, the circuit of the solenoid valve MV _{1 is} opened and the time delay relay T _{1 is} actuated at the same time. With the reversal of the solenoid valve MV ₁ to its previous position, the working direction of the cylinders 48 and 49 is reversed, and the pressure medium is introduced into the chambers A ^T or A ", whereby the winding disks 45, 45 ^{f are} moved inward towards one another, so that their projections 44, 44 * engage in the openings at the two ends of the new coil P _{1 brought} by the coil conveyor 20 (the coil P has already been ejected at this point) and the new coil P ₁ between the winding disks 45, 45 ^f is pinched.

Since the inside diameter D of the chamber A ^{1 of} the cylinder 48 is slightly larger than the inside diameter d of the chamber A ″ of the cylinder 49, the inward pressure exerted by the winding disk 45 is greater than that of the winding disk 45 * is provided with the step 50 the cylinder 48, the inward movement of the Wiokelscheibe 45 is stopped at this stage. Therefore, in order is more restrained than the package P ₁ by an action in which the winding disk 45 * with a weaker force pushes than the Winding disc 45, if the winding disc 45 is designed such that it is stopped in a predetermined position, the bobbin P ₁ can be placed exactly in the center of the machine frame at all times.

909828/0813

By switching over the solenoid valve MV., The direction of the pressure medium in the cylinder 5 is reversed in the previous direction, and the rack arms 2, 2 ¹ move downwards when the pressure medium is supplied to the chamber A. When the rack arms 2, 2 ¹ the new bobbin P ₁ between the winding disks 45, in the catfish described above, the curved plate 40, which is arranged on the end part 20 ^{1 of} the bobbin conveyor device 20 with the spring 42, is against the

Force of the spring pressed down Jn the open position. to release the coil as shown in Fig. j5, and after the release of the coil is completed under the Action of the spring 42 returned to its previous position.

If the Orenzsohalter Ls-4 has a suitable Mechanism (not shown) actuated briefly and the circuit of the solenoid valve MV closed becomes the direction of acting in cylinder 70 Pressure medium reversed and the piston rod 71 upwards pressed, whereby the levers 69 and 66 are rotated into the position shown in FIG. This will make the Clamping plate 6O pivoted and its end 62 against the upper Surface of the plate 38 pressed so that the course of the winding thread L is stopped. This movement is transmitted to the arm 64 via the link mechanism 66, 68, 67, and the pinch roller 65 is returned by the feed roller 57

909623/081

drawn.

Since the feed roller 57 rotates on the winding roller 1 by frictional engagement with this, the winding thread L is between the point at which the feed roller 57 is in pressure contact with the grooved winding roller Ί, and at the point at which the clamping plate 6o in pressure contact with the Guide plate 58 is cut off by the action of the tensile force of the rotating winding rollers 1, 1 ^1. Since the limit switch Ls-4, as already mentioned, only works for a short time, it returns to its previous position at the same time as the winding thread L is cut. Therefore, the solenoid valve MV is also returned to its previous position and the manner in which the compressed air acts on the piston in the cylinder 70 is restored. As a result, since the piston rod 71 is pushed down immediately, the operation is reversed. The clamping plate 60 is withdrawn from the guide plate 58, and since the clamping roller 65 clamps the thread end L ⁿ between itself and the feed roller 57 and rotates with the roller 57 by pressing against this roller, the end of the cut winding thread is immediately pulled out and is, after it has passed through the contact point between the grooved winding roller 1 and the contact roller 57, brought into the position in which it is wound onto the next bobbin. The new coil P ₁ , which is between the winding disks 45, 45 * of the rack

309828/0813

arms is clamped, is moved downwards by the compressed air fed into the chamber A of the cylinder 5 and is pressed against the grooved winding rollers 1, 1 * so that it rotates together with them. Since the outer surface of this bobbin P _{1 has} been moistened beforehand, the cut end L "of the winding thread, which has been advanced from the cut-off position described above to the position in which it is ready for winding, is wound onto the new bobbin.

Meanwhile, the cut end L " ^{1 of} the thread runs over the top of the grooved winding roller 1 and is wound onto the full winding L ¹ that has been ejected onto the upper side of the winding roller 1 * and the auxiliary roller 9.

After the series of operations described above has ended, when the contact T ¹ * of the delay relay T ₁ opens after the set time has elapsed, the contact R ¹ . of the relay R _{1 is} opened, whereby the solenoid valve MV _{2 is returned} to its previous state and the compressed air applied to the cylinder 36 is also returned to the previous state. It follows that the piston rod yj is pushed up and the coil conveyor device 20 is pivoted back into its starting position. This process also switches the limit switch Ls-3 back to its previous position Nc.

909828/0813

Together with the return of the coil conveyor device 20 to its previous position, the stops 24 and 22 are moved back to their previous position through the intermediary of the link mechanisms 27, 28, 29 and 50, 3I, 32. As a result, the spool P, (Fig. 2A), which was retained by one end 22 "of the stop 22, advances to the position in which it is stopped by the other end 22 'of the stop 22, while the spool P. ₂ , the fall of which was prevented by the stop 24, with the opening of the passage of the bobbin guide I9 by moving the stop 24 back into its previous position into the bobbin conveyor device 20, which has assumed its normal position again, where it falls through the bent end part 20 ^{f of} the device 20 and the plate 40 arranged on the front part 20 * with the spring 42 is held in such a way that it is ready for the next coil conveyance.

Further, since the solenoid valve MVj has returned to its previous state, when the contact R ¹ ^ is opened as described above, the direction in which the compressed air is applied to the cylinder I3 is reversed. The result is that the piston rod 14 is pressed downwards and the levers 10, 17 rotate about the shaft 12 as the axis of rotation and resume their previous position. Through this process, the full winding L ¹ , its winding on the upper surface of the grooved winding roller 1 · and

909828/0813

the auxiliary roller 9 has been continued to the outside of the Machine removed.

All of the related processes described above are automatically performed in a very short period of time without The machine was stopped during this period.

Instead of working automatically, manual operation is also possible. As can be seen from Fig. 8A, a manually operable switch S _{1 is} provided, which causes only the solenoid valve MV _{1 to work} independently of the operations described above, whereby the raising and lowering of the rack arms 2, 2 ¹ and the arrangement and removal of the Coil P are executed. On the other hand, a manually operable switch S ₂ only actuates the solenoid valve MV ₂ independently of the other processes in order to pivot the coil conveyor device 20 and eject the winding. Furthermore, by operating the push-button switch Pb, it is possible to selectively perform completely the same operations on a bobbin which is not fully wound to the prescribed extent as in the automatic operation which is carried out when a full winding has been wound.

The reel magazine 18 is equipped with a microswitch Ms provided, which closes the circuit of a warning device X and delivers a signal when there is no longer enough in the magazine Coils for replenishment are available.

909828/081?

In addition to the coil feeding device described is Fig. 2B illustrates the method of feeding a spool just prior to swinging the conveyor. In this procedure, the time of change of direction is the supply of pressure medium to the cylinder 80 is selected such that it takes place immediately before the series of removal processes, while the direction of the pressure medium supply is reversed takes place in the previous state after the end of the series of acceptance processes. This makes it possible to considerably shorten the time in which a bobbin is held in the bobbin conveyor device 20 and awaits the completion and ejection, i.e. the removal of a full winding. In In this case, the stop 24 is omitted, and the bobbin is dropped directly into the bobbin conveyor device 20 via the guide 19 by means of the stop 22.

The electrical circuit used in this case is shown in Fig. 8b. Br differs from the circuit shown in FIG. 8A in that a solenoid valve MVc for changing the direction of the pressure medium supplied to the cylinder 8o and a time delay relay T _{2 are also} provided. The time delay _{relay corresponding to the time delay relay T 1 of} the circuit according to Fig. 8A is shown in the circuit according to Fig. 8b as relay T-.

The operation of the last-described method is as follows: After a full winding has been obtained
