The scope of the double-entry policy is limited

The invention relates to automatic double-winding devices which are particularly used in cable winding machines.

In non-automatic winding devices, the winding reel is screwed in by hand until the gripper of this reel can be formally connected to the drive and braking system. Automatically operated wrapping or drawing machines use fully automatic double-winding devices. In use, the braking torque is transmitted by means of a friction clutch so that the coil is clamped between a fixed and axially movable stack and pressed against a leather or rubber plate fitted to the gripping disc. The transmitted torque is determined by the axial compressive force and the coefficient of friction between the rubber or leather plate and the coil flange. At higher winding speeds, this transmission based on the use of a friction clutch is no longer sufficient, because as the speed increases, the transmitted torque also increases.

The object of the invention is to ensure a reliable transmission of the operating and traction torque to the coil in fully automatic double-winding devices operating at high winding speeds without increasing the axial load of the coil bearing devices.

2 65407

The object of the invention is to provide a shaped connection of the spool to the drive and braking system, regardless of the angular positions of the winding pin of the winding spool and independently of the spool being pulled by the gripping disc.

According to the invention, this object is solved by using an axially movable spring-loaded gripping system rotating with the gripping disc, for example consisting of a perforated disc mounted on the gripping disc, on the circumference of which a plurality of flat springs are fixedly fixed to the sliders.

According to the invention, the perforated disc can be moved axially by means of a groove and a spring along the pin of the gripping disc and compression springs can be used behind the perforated disc.

According to the invention, a plurality of spring-loaded pushers guided in the sleeves are further fitted to the common hole circuit in the flange of the gripping disc.

According to the invention, the axial movement of the gripping pin arranged in connection with the gripping disc is dimensioned so large that in the event that the angular position of the reel gripping pin in the reel change does not correspond to the gripping disc gripping system, the reel can still be tightened between the stacks. The shaped gripper system according to the invention overcomes the limits of gripper systems based in particular on the use of friction clutches, which are based in particular on the fact that axial forces and neither rubber, leather plates can be increased indefinitely without wrapping the flanges of the winding rollers and prematurely running.

The invention will be explained in more detail below on the basis of some embodiments shown in the accompanying drawings.

Fig. 1 is a sectional view of the gripper disc and its shaped gripper and drive and braking system in the agreed position with the spool compressed in place.

Fig. 2 shows a partial section of the gripping disc according to Fig. 1 and its shaped gripper tightened.

Figure 3 shows a partial section of the gripping disc and its shaped gripper as a spring-loaded spring-loaded flange with a hub in a tensioned state.

Figure 4 shows a partial section of the gripping disc and its shaped gripper as a spring-loaded spring-loaded flange with a hub fitted in place.

Figure 5 shows a partial section of the gripping disc and its shaped gripper and the sleeves fitted to the gripping disc flange and the spring-loaded pushers therein.

Figure 6 shows a front view of a gripping disc with perforated discs and flat springs.

Figure 1 shows only the second spool support of the double spooling device, because the second spool support is similar in structure.

The spool bearing of the fixed but rotating pinol 2 is marked with the number 1. In connection with the pinol there is a drive and braking system 3 and a gripping disc 4. An axially displaceable Pinol 6 is fitted to the second spool bearing 5. The winding coil 7 and its cylindrical gripper 8 are shown tightened and formally connected to the drive and brake system. 3.

Fig. 2 shows a partial sectional view taken along line A-A of Fig. 1 of an embodiment of a shaped gripper, wherein 9 denotes the flat spring fastener and 10 the flat spring itself. The number 11 denotes a perforated disc to which the flat springs 10 are attached. It can be seen from the figure that the cylindrical gripper 8 of the wrapping spool 7 has compressed the hole disc 11 from its position due to the axial force of the stack 6, whereby the flat springs 10 are bent at the same time. In this case, the axial movement of the plurality of perforated flat springs suspended on the flat springs 11 causes the radial movement of these 4 65407 flat springs 10 in the fasteners 9, which must thus have sliding guides in which the flat springs can move radially back and forth. Sliding holes, for example, act as such sliding guides. According to Fig. 3, a hub 12 with a groove and a spring is arranged in the gripping disc 4, on which the perforated disc 11 is arranged axially slidably but non-rotatably. Compression springs 13 are arranged circumferentially distributed between the gripping disc 4 and the perforated disc 11.

Fig. 4 shows the same embodiment as Fig. 3, but with the device formally arranged in place.

Fig. 5 shows, as another example, coaxial sleeves 14 fitted to the flange of the gripping disc 4 and pushers 15 fitted thereto and compression springs 16 behind them.

Fig. 6 shows a front view of a perforated disc 11 fixed to the gripping disc 4 by flat springs 10 and gripping openings 17 fitted thereto.

The operation of the device according to the invention will be explained in the following on the basis of the embodiments 1 shown in Figs. 1 and 2, since other embodiments are also based on the same features of the invention.

When the winding roll automatically moves into place and tightens under the effect of the axially moving stack, it does not matter whether the cylindrical gripper 8 of the wrapping roll 7 meets the gripping openings 17 or not. Unless the gripper 8 and the gripping openings 17 are opposed, the hole disc 11 deviates in the axial direction as the flat springs 10 bend. When the winding reel 7 starts, the gripper of this reel fits into the gripping openings 17 of the hole disc 11 after a slight relative rotation, whereby a formal connection to the drive and braking system 3 is provided.
