the. has become known, a suitable connection is missing

In the previously known Bandaufwickelvorrich- a Kerrrwechsel- and cutting device for lines with rotary or turret head, the disconnection of the above disadvantages,
Mandrels, which carry the tape to be wound with 30 Finally, in the Austrian Patent Kernel, a device for exchanging stands arranged individually from one another, lying far apart in a fixed copy 212 686. In order to get one of tape-wound rolls, which, however, only smooth, wrinkle-free winding at the start of winding is suitable for unwinding the rolls, with the winding process on the core, it is important that the ends of the tapes overlap each other for cutting used flow 35.

The task on which the invention is based beam cuts through the new core, otherwise it is written in the simplest possible Aufwickelvor-Band not to create a smooth, even role direction, especially with constants Diameter is wound. This turn of sticky tapes and in continuous demand leads to the fact that a relatively long final winding operation of the new core smoothly and piece of unwound material on the wrinkle-free at the beginning of the wrapping process with the previously completed role remains. This end tape is wound and the finished wound core piece can be given a smooth and wrinkle-free circumference without being sticky and stretchable The quality of the tape is not as required that tape waste is generated. So with the invention would be created by hand smoothly on the otherwise finished 45 a device with which it put roll up roll. For this reason it must be possible to have cores smoothly from start to finish from each such roll about 15 cm tape of tape, especially sticky tape, to bewik-hand be cut off. none, without waste arising and without that

According to the German Auslegeschrift 1091 856, the winding process is a transition from a finished loading

although tape winding devices the initially wound core to the new core are interrupted

named species became known, but here is a must.

Proposed relatively complicated structure, this object is thereby achieved according to the invention which it is necessary to solve the support arms in two parts that in the device mentioned above execute, in such a way that the two parts support arms are designed as disc-shaped rotating heads are pivotable against each other. For this purpose, the mandrel support parts are always on one permanent articulated levers are provided, and the one for common, with the one common to the rotary heads each articulated lever required double axis concentric circle that adjacent Swivel mechanism and the mutual tuning mandrel support parts at different rotation These mechanisms mean heads are arranged on top of one another and the mandrel T rageinen complicated structure. In addition, it is necessary to have 60 parts of the cores further away, the winding axles when passing through arranged rotating heads through part-circular designs Paper web due to axial displacement of the slots of the adjacent cores to move as well as an additional drive rotating heads protrude that the drive device vorzuschen, which only during the beginning of the device the mandrel support parts essentially Wickd process is in operation. This results in 65 directly oneine during the entire winding process difficult guidance of the wound roll drives and that the tape cutting device drives the tape along the perimeter of the common pressure roller on one in the immediate vicinity of the newly to be bcwikrolle. cuts through the core, while

The finished roll is still rotating and is moved to the disengaged position.

In particular, there are two core putters that can be set in rotary motion by individual motors are trusted by two rotary heads, which pivot independently of one another around a common axis. or are rotatable. During part of the machine cycle, the turning heads are turned simultaneously switched so that a new core gets into the winding station and that completely with tape wound roll removed from this winding station and in operative connection with a first, of one pivotable arm carried pressure roller is brought. When the new core is in the changing box is moved, it is not in rotation, and when it has taken its wrapping position a flying knife is operated, which attaches the tape to one in close proximity to the new core cuts through. The finished roll remains during and after the cut through of the belt initially in a rotary motion, so that the first pressure roller interacts with the belt in such a way that that the end piece is wound smoothly onto the practically finished roll. Immediately after When the tape is cut, the new core is set in rotary motion, with a second Pressure roller the adhesive side of the tape is pressed against the new core, so that the tape wrapped in a roll around this core. While the wrapping process continues, the rotary motion will the previously completed role, while the rotating head carrying this role continues is switched or pivoted into an end position in which the finished role is then in the Unloading station is located. Each core pair is on a straight diameter line of the corresponding rotary head arranged so that when the previously completed roll is in the unloading station, the Corresponding core of this core pair in the standby position, d. H. at a predetermined distance from the changing station is. The two rotating heads work like a pair of scissors, whereby neighboring ones Cores are brought relatively close together in the winding station, so that the tape in this position cut through and then the finished roll can be moved from this position into the unloading station can, while at the same time a new core to continue the winding movement in the winding station is promoted.

In this way, the invention provides a substantially improved one with rotary or turret heads working device for the continuous winding of tapes on rolls created.

In particular, it is possible with the device according to the invention to wind a tape onto cores, which are successively moved into a winding position or station, with the tape automatically cut through, the beginning of the cut tape attached to a new core and the tail of the cut tape is wrapped smoothly around the practically completed core.

With the invention, a tape winding device has been created, which is a common Axis having rotatable pair of rotary heads and removably attached to each of the rotary heads Mandrels and further a device for switching or pivoting the rotary heads, with which moves a mandrel into the winding position or station and after a predetermined period of time is exchanged for a neighboring mandrel, the latter in the winding position or station remains, while the former

is moved into the unloading position or station;

there is also a device for rotating the ta

the mandrels located in the winding position or station intended.

In Fig. 1, an outer shaft IO is shown, which is rotatably mounted in a vertical frame consisting of frame parts II. Airdicer shaft is mounted in the first rotary head 12 on which a pair of opposed mandrel support members / 1 and C are arranged. A second rotary head 14 is attached to an inner shaft 13 and carries a pair of opposed mandrel support members / J and Π. The two shafts can be rotated independently of one another about a common axis, so that the spacing between adjacent Auispamulorn support parts can be changed at predetermined points in the working cycle of the machine.

The mandrel support parts, the fitting parts a suitable mechanism that leads to the represent, are still on a hydraulic rotary heads and the pivoting of the pressure roller Motor coupled so that a single clamping 22 switches. In detail, as in FIG. 4 mandrel support, which is shown in the tape winding position, the pressure roller 22 is pivoted so that is rotatable.

Winding devices to a relatively long end of unwound material on the practically completed role; it is not possible to put this end on the roll in a smooth shape by hand because the tape is sticky and stretchable S. As a result, in known winding devices Cut about 15 cm of tape from each finished roll. However becomes the distance between adjacent cores in a tape winding device according to the invention changed automatically at predetermined points in the machine's work cycle. Here is the distance between the wound tape roll and the new core at the moment when the flying Knife cuts through the ribbon, reduced to a minimum. As a result, although the The path of the tape is cut, as required, in the immediate vicinity of the new core, including that in the end of the already wound roll that has not yet been wound up, very short. The knife cuts the web in such a direction that the new beginning of the tape during cutting through is pressed against the new core, automatically attaching the tape to the core is attached for winding a roll.

In detail, the right, vertical machine frame consisting of frame parts 11 and the outer tubular shaft 10 can be seen in this figure. The figure also shows four clamping mandrel supports / f, H. C and /), the pressure roller 25 carried by the swivel arm 27 and the hydraulic cylinder 24 to which the swivel arm 27 is coupled. These reference symbols coincide with the reference symbols of FIG. The structure and arrangement of the mandrel support elements is described in more detail below. First of all, it should be pointed out that the mandrel, which carry the cores to be wound with tape, are detachably connected to the mandrel support members. In I ⁷ vol. ^ Three of the mandrels are visible, which are designated 35, 36 and 37. One of the Diehköpfc comprises the outer shaft 10, at one end of which an end / almiad 40 is attached! is, in which a pair of arcuate openings are provided, which are hereinafter referred to as part-circular slots. The other rotary head comprises a shaft which extends through the annular shaft 10 and a similar end gear 41 which is attached to the protruding end of that shaft. The end gears 40 and 41 are provided on opposite sides of the machine frame. The first pair of mandrel support members A and C are attached to one side of the Fnc '/ ahnradcs 40 !, while the associated drive motors 42 and 43 are mounted on the opposite side of the end gear. These motors are visible through the corresponding partial circular slots in the two fuselage rings. Each of the two mandrel supports A and C carries rotatable shafts which pass through the circular slots of the end gear 41 and are coupled to the associated motors. In the same way, the two clamping mandrel traps Ii and /) as well as the motors assigned to them are attached to the F.nd / ahnnul4l befcMipl. the connecting shafts passing through the arcuate openings in the end gear 40. A first drive gear 45 mounted on a shaft 46 meshes with the end gear 40, and a second drive gear mounted on the shaft 47 meshes with the end gear 41. One of the pivotable arms 48, which supports the flying knife, is also in FIG. 9 visible.

FIG. 10 shows a partial isometric view showing the outer side of the right machine frame. The second drive gear 50 can be seen here, which meshes with the end gear 41 of the one rotary head. In addition, one can see the two driving motors 51 and 52 assigned to the second pair of mandrel support parts B and D as well as part of the mandrel support part D. It can easily be seen that the two end gears 40 and 41 rotate simultaneously by means of the two drive gears can be offset or that one of the two end gears can be rotated while the other is stationary. The simultaneous rotary movement of the two end gears corresponds to a simultaneous rotary movement of the two rotary heads designated by the reference numerals 12 and 14 in FIGS is moved in). The working state, in which one of the two end gears is rotating while the other is stationary, corresponds to the pivoting or turning of the rotary head 12, which, as shown in FIG. In Fig. H! four rigid tubular holders 54 to 57 are also shown, to which a heavy end plate is attached! the purpose of which will be clarified further below.

It can now easily be seen that the rotatable. Furthermore, axial displacements are four rollers, which are prevented by means of the four associated »s of the rotating heads, which means that the nuts 130 to 133 (Fig. 10) are carried, wound rollers have smooth ropes,

A corresponding arrangement of angle- These rollers are intended to allow an axial displacement of the lever and stop is provided on the end gear of the two F.ndzahnrädcr relative to the machine frame of the other rotary head. Prevent with this. In Fig. 17, the hand gears are shown in the written arrangement, a precise setting of a position in which the inner 55 of the mandrel support members in the winding station rolls 140 and 140 ' in correspondence and in, so that the flying knife to be passed through The uppermost point of their circulation is the band very close to the new one. In Fig. 18 the two end gears are arranged on the core and all rollers are rotated smoothly opposite, so that these particular ones are wound.

is wound onto the core 161 , which in turn is arranged on the mandrel 35 . In contrast, the spring 163 holds the pressure roller ZS in a normal position, which is determined by a fixed stop 164 . Furthermore, an electrical control circuit is shown, which includes electric motors for rotating the mandrels. The one from the engine

165 driven main drive shaft 74 rotates continuously during the operation of the machine. Two electromagnetic clutches 166 and 167 are arranged on this main drive shaft, which are normally de-energized. When the clutch

166 is connected to the electrical power source, then the sprocket wheel 76 'is coupled to the main drive shaft 74, whereby the shaft 46 assigned to the one rotary head is set in rotary motion via the sprocket wheel 76. This results in the rotation of the drive gears 45 and 45 'which mesh with the corresponding end gears 40 and 40' of the inner turret. In the same way, by switching on the coupling 167, a rotation of the shaft 47 assigned to the other rotary head is achieved via the chain gears 77 and 77 ', so that the drive gears 50 and 40 mesh with the corresponding end gears 41 and 41' of the outer rotary head 50 'are set in rotary motion. On the end gear 40, a pair of mandrel support members A and C with the respective motors 42 and 43 are arranged; this is in axial correspondence with the corresponding mandrel support parts located on the associated end gear 40 ', of which only the mandrel support part / T is shown in FIG. The other pair of mandrel support parts B and D and the associated motors 52 and 53 are arranged on the end gear 41 and are located in correspondence with corresponding mandrel support parts on the associated end gear 4Γ, the associated mandrel support parts D and D ' are in -the unloading slalion, while the associated mandrel-Tiagleile A and A 'are in the winding station.

The two electromagnetic clutches are de-energized, the two rotary heads are held in fixed positions, and the web 16 is wound onto the core 161 to form a roll 30, the core 161 being pushed onto the mandrel 36 coupled to the mandrel support part A. The motor 42 is switched on, one end of the molar winding being connected to ground and the other end 168 being connected to the closed contacts 169 of a power circuit 170. This relay is normally open and, as will be explained in more detail below, is actuated shortly after the mandrel support members A and A ' enter winding. Suffice it to say, first of all, that this relay is electrically switched on by the normally closed contacts of a switch 172. The switch 172 is provided with an actuating pin which is in the path of a stop 173 located on the end gear 40 '. This electrical lock-in circuit or self-return circuit runs via the closed contacts of the switch 172, which are connected to the positive pole of the power source, via the line 174, the closed Uelaiskonlakte 175 as well as the return coil 176 and the line 177 connected to ground .

A cam disk 179, which rotates together with the roller 31, opens and closes a switch 180 and in this way generates electrical impulses which are input to a conventional counter 181. When a predetermined number of pulses, which corresponds to a specific length of tape wound onto the roll, has been registered on the counter, a switch 182 is closed in the counter U1. One contact of this switch is connected to the positive current connection, while the other contact is led to the actuating coils of two normally open power relays 183 and 184 . If the contacts 185 of the power relay 183 are closed, then this operates as an electrically self-holding relay via the normally closed Schaller 186, which has an actuating pin located in the path of the stop 173 of the end gear 40 '. The self-holding circuit runs through the switch 186 connected to the positive terminal of the power source, the line 187, the now closed contacts 185 as well as the relay actuation coil 188 and the grounded line 189. In the same way, the power relay 184 becomes an electrically self-holding relay when it closes of contacts 190, one of which is connected to the relay actuation coil and the other is connected via a line 191 to a fixed contact 193 of a two-pole changeover switch 194. The two-pole changeover switch 194 has an actuating pin which lies in the circulation path of a stop 195 attached to the end gear 4Γ. Contact 193 is normally in contact with movable contact 196 of the switch which is connected to the positive terminal of the power source. The electromagnetic clutch 166 is connected to the circuit via the now closed contacts 197 of the power relay 183, while the clutch 167 is connected to the circuit via the now closed contacts 198 of the power relay 184. Therefore, the two shafts 46 and 47 are set in rotation when the switch 182 of the counter 181 is closed. These shafts rotate as long as the power relays 183 and 184 remain on. When the two rotating heads turn as a result, the wound and still rotating roll 30 moves out of the winding position and comes into contact with the pressure roll 25. At the same time, a new mandrel, which is coupled to the mandrel support part B, moves into the core Changing station. If the not yet rotating new core is in the winding position, then the stop 195 provided on the final gear 4Γ opens the contacts 193 and 196 of the switch 194, so that the electrical "lock-in" or self-holding circuit of the power relay 184 opens, whereupon this falls back into its normally olfactory position. When the Rclaiskontaktc 198 is opened, the electromagnetic clutch 167 is switched off from the power source, as a result of which the rotary movement of the outer rotary head, on which the end tooth brackets 11 and 4 are arranged, is stopped. It should be pointed out that the clutches used are conventional clutch-brake devices with which it is prevented that the rotary heads run beyond these during the transition to certain positions. Although the rotary movement of the iiul.V-ren rotating head has stopped, iliis I.eisiimi'.s-

209 627/195

relay 183 is turned on and the inner turret continues to rotate.

When the new core is in the winding position, contacts 196 and 200 of switch 194 are closed, thereby connecting the positive terminal of the power source to the normally open switch 201 associated with end gear 40 '. Shortly after the rotary movement of the outer rotary head has been stopped, the stop 173 provided on the still rotating end gear 40 'briefly closes the contacts of the switch 201, whereby the solenoid 202, which actuates the flying knife 16 to cut the web, is energized is applied. At the same time, by briefly closing the switch 201, the actuating coil 203 of the relay 204 is charged with current, the circuit via the now closed contacts 196 and 200 of the switch 194, the lines 205 and 206, the briefly closed switch 201 as well as the line 207 connected to the non-grounded side of the relay actuating coil 203. When the upper relay contacts 208 close, the relay 204 goes over electrically to self-holding mode via the normally closed switch 209. The switch 209 is provided with an actuating pin which lies in the circulation path of the stop 195. The self-holding circuit runs via the closed switch 209 connected to the positive current connection, the line 210 and the relay contacts 208, which are connected to the non-grounded connection of the actuating coil 203. If, on the other hand, the lower relay contacts 212 are closed, then the motor 52 coupled to the mandrel support part B is switched on via the line 213. The tape is now wound onto the new core, but the inner rotary head carrying the roll 30 that has just been wound is pivoted further. When the stop 173 provided on the final gear 40 'depresses the actuation stop of the switch 172, this switch opens and thus the electrical self-holding circuit of the power relay 170. The power relay then drops out, the contacts 169 open, and the motor 42 is switched off .

The motor 42 is switched off at a point in time after the fully wound roll 30 in Has come into contact with the pressure roller 25, so that what remained when the tape was cut The end is wound smoothly onto the finished roll. Then the stop 173 opens the switch 186, to switch off the electrical self-holding circuit. The power relay drops out when the contacts open 197 the connection to the coupling 166 is turned off and the rotary movement of the inner rotary head stopped. At this point in time, the completed roll 30 arrives in the unloading position.

As already explained above, the ribbon is cut by the flying knife in close proximity to the cut through new core immediately after this core comes into the winding position is. During the cutting process, the adhesive side of the tape is pressed against the new core, whereby the new beginning of the tape is automatically added to the core. About the same time as that When the tape is cut, the new core begins to rotate and the tape is wound up a second roll is continued while the previously finished roll 30 is in the unloading position is moved and is initially held there. The winding up of the second roller blind is carried out during the the next further switching of the rotary cap and up to the point in time at which the on End gear 41 'of the outer rotating head provided stop 195 opens the switch 209, whereby there « Relay 204 drops out, so that relay contacts 212 open and motor 52 is switched off. The The next resounding of the rotary heads starts after a predetermined number of pulses from the counter 181 has been registered.

In Fig. 20 only those relays, switches and the switch actuating stops are shown, as far as this is to explain a work or Winding cycle of the machine is required. It is readily apparent that corresponding additional components can be provided so that the above-described functional sequence can be carried out four times in a row, creating a complete Circulation of the rotary heads is effected. Each of these functional processes can be briefly summarized as be characterized as follows-

1. Simultaneous rotation of the inner and outer turret after a first roller, for example carried by the inner rotary head, reaches a predetermined diameter has;

2. Continuation of the rotation of the inner turret after the rotation of the outer one has ceased Rotary head with which a new core has been brought into the winding position;

3. Actuation of the flying knife after the new core is in the winding position and while the first roller is still rotating and moving to the unloading position;

4. Beginning of the rotation of the new core, either at the same time as the cutting through of the tape or immediately after;

5. Winding up the cut end of the tape onto the first roll by means of an and the unloading station arranged pressure roller;

6. Completion of the rotary movement of the first roller before this roller reaches the unloading position;

7. End the rotation of the inner turret so that the first roll is in the unloading position is stopped, and

8. restart the simultaneous rotation of both rotary heads after the second roll one has reached a predetermined diameter.

In the device according to the invention, adjacent cores are arranged on different rotary heads, and the smallest possible angular distance between one in the winding position and the next following core is determined by the diameter up to which the roll winds shall be. In a given machine according to the invention, this angular distance is so small as possible, which means that after cutting the tape, only a short to the practically finished roll to be wound tape end remains.
