with means for annealing the wire through are free, be it for example that they are damaged or electrical resistance heating together. In the sense of the previous explanations, errors in this is caused by the sticking in the annealing zone because they are not using the correct manufacturing machine The piece of wire located was subjected to a low tensioned 30 conditions. These imperfect sent electric current, whereby the piece of wire parts give rise to various difficulties, by the thermal effect of the electric current on the winding machine mentioned at the beginning

the annealing temperature is heated. The prior art annealing requires two coaxial turning Current depends on the resistance of the driven drums used. Here is the Material and the speed at which the wire fed to the main drum by about one Wire passes through the annealing zone. With those who are currently one-thirds of the drum circumference wrapped around, they ended Machines are wire speeds from then via a swiveling guide roller to the auxiliary power, for example 250 'to 2500 ni / min common. In such a mel led and attached to this. When switching The wire winds itself at first for correct annealing of the drum drive required current to be so large that it, during the 40 on the auxiliary drum. If the useless Wire is at rest or before the correct wire starting piece has been taken up by the auxiliary drum, speed is achieved, the wire can not be fed by swiveling the guide roller under because otherwise the wire in the annealing zone would melt. Back and forth on a laying device For this reason, during the acceleration, the main drum is wound up, while the auxiliary drums of the wire 'at start-up' of the annealing machine 45 drum removed after cutting the wire. and during its shutdown delay, it can be hard, drained, and drained.

unannealed wire ends, which are applied to auxiliary trunks with devices of the generic type so that there is only properly treated wire on the main drum.

From the foregoing it can be seen that when winding the from a wire making machine supplied wire often the case that the ends of the wire for various reasons do not work properly.

However, the known rewinder has some disadvantages. This is the case with the known rewinder due to the necessity of a swiveling guide pulley a proper function is made difficult. This roll must be swiveled by hand after winding the waste piece onto the auxiliary drum, to transfer the wire to the main drum. The machine therefore requires constant over-

In contrast, the invention is essentially characterized in that the laying mechanism after Winding of the auxiliary drum can be switched on automatically and the wire is guided through this in such a way that the wire by wrapping it on the main drum located wire loop is set on the main drum and wound up by this, wherein the wire is severed at the same time or immediately thereafter between the auxiliary and main drum will.

In this way, there is a fully automatic change from one that takes place at predetermined times Drum reached to the other, so that the operating or monitoring staff largely switched off especially since the change occurs independently of the operating personnel. Another The advantage of the invention is that the wire can be severed in a particularly simple manner. "

The switching angle of the wire on the main drum is more than half a wire turn. If necessary, the wrap angle of the wire can also be greater, for example more than 360 ° be.

The winding device of the type specified at the beginning is characterized according to the invention from that the laying device is movable along the main drum in such a way that one of these initially The supplied wire part can be wound over and thus can be fixed for further winding of the main drum.

The invention is described below with reference to drawings. In the drawing are as an example various embodiments for wire winding devices according to the invention shown, intended for use in winding the wire supplied by an annealing machine. Illustrated in the drawing

In Figs. 1 to 3 and in particular in Figs. 1 and 2, a device is shown which comprises a shaft 1, on which a main drum 2 is removably arranged. The shaft 1 is through (not shown) Devices, for example from the main drive shaft of the devices shown in FIGS. 1 and 2 cooperating annealing machine, powered.

The device shown in Figs. 1 and 2 further comprises a shaft 3 which is at a distance from the Shaft 1 is arranged and runs parallel to it. An auxiliary drum 4 is removably arranged on the shaft 3, which is driven by this shaft. The shaft 3 can optionally from the shaft 1 over a drive belt 31 and an electromagnetic clutch 32 are driven.

In operation of the apparatus shown in Figs. 1 and 2, after a first imperfectly manufactured scrap piece of wire W has been wound onto drum 4 in the manner described below, the properly annealed wire is wound onto drum 2. In this embodiment of the device, the wire W supplied by the annealing machine is fed to the drum 2 by a guide roller 5, but differently designed guides, for example fork-shaped guides, can also be used. While the annealed wire is being wound up on the drum 2, the roller 5 is moved back and forth in the usual manner over the length of the drum, so that a helical winding is produced.

The guide device which gives the roller 5 the reciprocating movement is accommodated in a housing 6 and comprises two slidably arranged rods 7 and 8 on which a downwardly directed arm 9 is fastened near one end thereof. At the lower end of the arm 9, a rod 5 a is adjustably arranged, which carries the guide roller, which together with the rod 5 a and the arm 9 forms a laying device.

The rods 7 and 8 are connected between their ends by a bracket 10 on which one at 12 pivotably arranged pawl 11 engages. The pawl 11 is closed by a spring 13 on the bracket pressed. The rods 7 and 8 can be moved back and forth by a pivotably arranged arm 14, its movement by a pivotably connected to the arm 14 connecting piece 15 on the Rods 7 and 8 is transferred. The arm 14 carries a cam roller 16. which against a heart-shaped Cam 17 pushes with flanks 17 a, which is arranged on a shaft 18 and of which in usual Way the pivoting movement of the arm 14 is derived. The cam 17 rotates, for example clockwise. The shaft 18 is connected to the shaft 1 by a transmission (not shown) and is constantly driven in this way.

The cam disk 17 also drives a second, pivotably arranged arm 19 which carries a cam disk roller 20. The cam rollers 16 and 20 are brought into contact with the cam disc by a spring 21 arranged between the two arms 14 and 19. A soft iron rod 22 is also connected to the arm 19, one end of which protrudes into a coil which, together with the soft iron rod 22 and a relay RC, forms an electrical switching device which will be explained below with reference to FIG.

Before starting to wind up the wire on the main drum 2, the piece of wire must be separated between the main drum 2 and the auxiliary drum 4. In the one shown in Figs Device, the separation is effected in a known manner by a cutting edge 33, which by a device (not shown) can be brought to bear against a fixed stop 34.

The electrical switching device of the machine comprises in accordance with Fig. 3 Anbeitskontakte DM and Tl and normally closed contacts T2, which together with the control circuit MC a delay unit MC, T2. The con-

cycles DM are closed at the same time as the switch for the main motor of the annealing machine. The contacts and T2 are only opened or closed after a short period of time has elapsed after the glow current was switched on by closing contacts (not shown).

When carrying out the method according to the invention, a piece of the wire W to be annealed (FIGS. 1 and 2) is guided through the annealing machine and over the guide roller 5. A wire turn W _{2 of} the incoming wire W ₁ is then placed on the main drum; the end of the wire is inserted into a fastening hole 4 a of the auxiliary drum 4. Then the switch for the main motor of the glow machine is closed. As a result, in addition to the main shaft of the annealing machine, shaft 1 (FIGS. 1 and 2) are driven and contacts DM (FIG. 3) are closed. As a result, the control circuit MC of the magnetic coupling 32 is excited via the normally closed contacts T 2. In this way the drum 4 is driven at the same speed as the drum 2, the latter acting as a capstan through which the wire is fed to the drum 4. The wire supplied by the annealing machine at this time has not been exposed to the heat effect of the annealing current, so that the wire wound on the drum 4 is unannealed waste. However, when the annealing machine has reached its full speed, the annealing current is fed to the wire passed through the annealing zone of the annealing machine, so that properly annealed wire is supplied by this which is wound onto the main drum 2. The winding on the main drum is initiated in that the contacts T 1 are closed. The contacts T 1 are closed after a short period of time has elapsed after the supply of the glow current, as already indicated. This period of time is dimensioned such that the contacts T 1 do not close until a short time, for example 1 second, has passed after the glow current has been switched on. This is done to ensure that the unannealed wire has fully reached the auxiliary drum 4 before winding on the main drum begins.

By closing the contacts T1 , the coil circuit is closed via the normally closed contacts RC 1. If the soft iron bar 22, as can be seen from FIG. 3, is not drawn into the winding /, the reactance of this is low; the voltage on the winding of the relay RC is insufficient to energize it. However, as soon as the soft iron rod 22 is moved into the coil / in by the arm 19 during the revolution of the cam disk 17, the reactance rises until the relay RC is energized, as a result of which the operating contacts RC%, are closed and the solenoid 5 ″ is energized. RC is an automatic relay; as soon as it is energized, the circuit of the coil / can be opened by opening contacts RC 1.

When the solenoid 5 is excited, the pawl 11 is disengaged against the pressure of the spring 13 the bracket 10. The rods are thereby freely movable and move - as can be seen from FIG - To the left as soon as the roller 16 on the arm 14 over the part 17 a of the outline of the cam 17 is running.

During this movement of the rods 7 and 8, the guide roller 5 guides the part W _{1 of} the wire W over the part W ₂ and tightens between them on the surface of the drum 2. The cutting edge 33 rests against the stop 34 essentially at the same time as the shifting of the roller 5 to the left and cuts off the wire running between the two drums. As a result, the remaining wire W is helically wound on the drum 2 during the subsequent reciprocating movement of the roller 5.

After the wire running between the two drums has been severed, the normally closed contacts T 2 of the delay device MC ₁ T 2 are opened. As already mentioned, these contacts are opened after a certain period of time. The operating speed of the device is normally such that the period of time which has to elapse after the supply of the glow current and before the contacts T 2 are opened does not exceed 2 seconds. When the contacts T 2 open, the excitation circuit for the winding MC of the magnetic coupling 32 is disconnected, so that the drive of the drum 4 is interrupted. The drum 4 can then be removed from the shaft 3 in order to remove the accumulated waste wire in the usual manner. The drum can then be attached again to the shaft 3 for the next start-up process of the machine.

The modified embodiment of the winding device shown in FIGS. 4 and 5 comprises a Guide device which is arranged in a housing 50. The guide device is in the same Formed as that shown in Figs. 1 and 2 and is therefore not described in detail.

In this embodiment, a shaft 51 carries both the main and the shaft in a known manner Auxiliary drums 52 and 54, both of which are removable on the Sit shaft and are driven by it, the flanges 52 a and 54 a bear against each other.

When carrying out the method according to the invention, the wire supplied by the annealing machine is guided over a guide roller 55 that moves back and forth, ie that forms a laying device, and then a turn is applied to the main drum 52. The wire is guided past the partition wall formed by the two flanges 52 a and 54 a by means of a roller 56 and the free end is fastened to the drum 54. The stationary roller 56 is rotatable about an axis which is at a distance from the common axis of the drums 52 and 54 and which extends at right angles thereto. The tension ″ in the wire W is maintained by a drum 52 which is carried by an arm 58 pivotably arranged at 58 a, the roller 57 being urged upwards by a spring 59.

Then the switch of the main motor of the annealing machine is closed. In addition to driving the main shaft of the annealing machine and thus the shaft 51, the contacts T (FIG. 6) are thereby closed after a certain period of time. The period of time is such that the contacts T are not closed until a period of 1 to 2 seconds after the supply of the glow current to the wire, which current is supplied no sooner than until the wire at full speed through the Glübzone is moved.

When the normally open contacts T are closed, the circuit of the coil / is closed via the normally closed contacts RC 1. If, as in the device described with reference to FIGS. 1 to 3, the soft iron rod 22 moves into the coil /, the binding resistance is increased until the self-holding relay RC is energized, whereby the normally open contacts RC 2 are closed and the solenoid S is energized.

In a manner known from Ziehroaimeln, a wire winding C is produced after actuation of the Abstelle, which sits loosely on the drum or stop switch of the Attsglühmaschine the machine mel. The drum 64 can expediently not be switched off immediately. Instead, it will be provided with a removable cover 69, which only prepares a circuit with the drum 64 for actuating the stop switch, an annular opening 70 45 through which the switch-off later forms. In practice, this opening can cause a large actuation of the limit switch, for example one and a half times the diameter. Thus, after actuation of the stop switch, the wound wire runs. By continuing the wire through the annealing machine for a period of time, attaching the lid 69 ensures that it is being annealed in accordance with the regulations. As soon as each wire of the loose wire winding C is on the part 50 after the circuit is prepared, the 68 remains and does not migrate back onto the part 65 guide 75 the next time the rightmost end and unwinds. reached their movement and thereby to the part 78

Since the waste wire strikes when the one shown in Fig. 7, the limit switch is operated and auxiliary drum form is used, in the form of a shutdown. At the same time the loose winding is produced, it can easily be removed from the drum rod 76 to the right, so that the hook-shaped cables can be removed as soon as the cover 69 deflecting device 77 has removed the wire W onto the drum 73. By using this trom- leads. During the subsequent rotation of the melter mold, a further, however, when drawing shaft 71, the imperfectly produced advantage known from wire is achieved. The wire W, the end piece of the wire supplied to the annealing machine, is wound on the drum 73, which is always fed 60 directly to the surface part 65. After this fall off, the auxiliary drum travels at a constant linear speed towards that properly established on drum 72.

Claims (19)

At the time of the changeover, there is no change in the feed speed of the wire W, so that reliable operation is ensured. In the device shown in FIGS. 4 to 6, a single drum with an intermediate wall or a flange can expediently be used in some cases, which divides the drum into two winding elements. When using the device shown in FIGS. 4 to 6, the wire running between the two winding elements should be separated by the influence of the increase in tension. According to FIGS. 1 to 3, it is separated by a cutting edge 33. However, other devices can also be used for the separation; for example, the cutting edge 33 with the stop 34 can be replaced by two metal disks. At the appropriate moment, an electric current sufficient to melt the wire is passed through the disks. In Figs. 1 to 4, the wire W is shown as being applied to the main drum with a full turn. In certain cases, however, it may be useful to apply more or less than one, but at least more than half a turn, so that during the displacement of the wire guide roller 5, a part of the wire fed to the main drum is a part of the wire that has already been applied to it, specifies.
