are offset from one another, is changeable. Me position of the offshoot in relation to the wall of the fixed container can be adjusted by turning an eccentric, whereby the offshoot is set so that turns of bands of different thicknesses are stored in the same arrangement in relation to the wall of the fixed container _β

A depositing device Io according to the invention for depositing a ribbon, i.e. an undeserved strand of textile fibers, in a stationary container 12 is shown in Fig. shown. The belt is by one on the rotatable Deposits 16 arranged roller pair 14 conveyed into the stationary container 12. The tape is on exit from the pair of rollers 14 by the clockwise rotation of the first transfer drive 24 by the distance shown in FIG. 1 and 4 with 2o designated center axis in rotation offset offshoot 16 laid in turns. Simultaneously with the rotation of the deposit 16 about the first axis 2o and the conveyance of the tape into the stationary container 12 by the As a pair of rollers 14, the offshoot 16 is set in rotation about a second axis which is opposite to the first axis. 2ο offset and coincides with the central axis of the stationary container 12. The rotation of the offshoot 16 to the second axis 28 causes the turns 32 to be offset

009018/1229

of the tape (see Fig. 2) against each other, so that the tape by doing. stationary container 12 in the form of a double helix that is, it is deposited with turns offset from one another and packed in a number of layers. A second drive 34 sets the cradle 16 clockwise (as in Fig. 1 in plan view) about the axis 28 in Rotation, in that the base plate 36 on which the support is arranged is set in rotation

It is contemplated that the depositing device may be used for depositing or packing tape of various thicknesses roller pair 14 and the vertical wall of the container 4o adjusted through the device, "the adjusting 4o allows the storing of tape of different thicknesses in the stationary container 12 in such a manner that, as shown in Fig. 2 at 42, the outer periphery of the turns rests against the cylindrical wall 44 of the container. For this purpose, the adjusting device 4o has an eccentric 48 (see FIGS. 1, 3 and 4) which is rotatably inserted in a circular recess 5o of the base plate 36, so that the distance between the axis 2o and the pair of rollers

- 8 009818/1229

from the central axis 28 and the wall 44 of the container can be changed. Suitable securing devices 54 (see pigs 3 and 4) secure the eccentric 48 against unwanted rotation after the offshoot 16 is in a certain position in relation to the wall 44 of the container has been set.

The roller pair 14 is arranged on the offshoot 16 and rotates with it about the axis 2o. To that end is the pair of rollers 14 on a circular plate or a Plate 58 of the offshoot 16 arranged (see Pig. 3 and 4).

A generally circular, axially extending rim 6o (Pig. 4) is mounted on plate 58 by clamps 64 attached. The offshoot 16 is through a between the wreath 6o of the offshoot and a ring To of the eccentric 48 inserted bearing device 66 rotatable relative to the eccentric and the base plate 36 (see Pig. 4 and 6). JJie Bearing device has an outer ring 72 fastened to the rim 7o of the eccentric 48 and an inner ring 72 with which Ring 74 connected to the ring 74 of the offshoot 16. Suitable Rollers or balls 76 run in the rings 72 and 74, whereby the offshoot 16 is rotatably guided with respect to the eccentric 48 and is secured against axial displacement. Of the

009818/1229

'feller 58 reaches into a recess 80 of the eccentric 48, in order to additionally secure the offshoot 16 against upward axial movement. This additional backup of the offshoot 16 against upward displacement turns out to be necessary because of the pressure that the Tape exerts on the bottom of the deposit when the container 12 is full and more tape is pressed into the container will.

The offshoot 16 with the pair of rollers 14 is through the first Gear 24 driven to rotate about the axis 2ο of the offshoot 16, so that the belt conveyed into the container by the pair of rollers 14 is deposited in the form of a spiral. The belt is fed to the roller pair through the funnel 84 (Figo3 and 4) fed downwards into the intake of the pair of rollers 86 driven by the roller pair drive 92 and 88 extends, and is further conveyed through a pipe 94 and an opening 96 in the plate 58. The pair of rollers 14 is driven by the drive device 92 while the depository 16 rotates, thereby conveying the tape through the opening 96 into the container 12. This causes the previously described rotation of the deposit 16 about its central axis 2o the depositing of the tape in the form of turns in the Container 12.

In order to ensure that the tape is laid in even turns 32, the speed at which the Belt is conveyed through the pair of rollers, in direct proportion the speed of rotation of the offshoot 16 relative to the base plate 36. This is caused by the Power transmission to the roller pair drive 92 takes place through a spur gear loo, which through a recess in the Ring 6o (Fig. 3) through with a ring gear Io4 on the inside of the ring 7o is in engagement. Since the Ring gear Io4 is rigidly connected to the eccentric 48 and thus does not rotate relative to the base plate 36, causes the rotation of the offshoot 16 relative to the base plate 36 a drive of the spur gear lob and thus the pair of rollers 14. The rotation of the spur gear loo causes the drive of the pair of rollers 14 via the device 92, which Interchangeable gear Io8 mounted on the shaft Ho which is in engagement with a second replaceable gear. The gear 114 is in turn on the Shaft 116 (see Fig. 5) attached, which also carries the bevel gear 118, which is connected to the bevel gear 12o of the lower Roller pair roller 88 is engaged. The upper roller pair roller 86 is positioned on the shafts 128 and 13o of the rollers 88 and 86, in engagement with one another Gears 124 and 126 driven.

Simultaneously with the rotation of the lay-up 16 about its axis 20, the lay-up is set in rotation about the central axis 28 of the container 12 in order to offset the turns 32 ″ of the laid tape against one another The length of the tape required for the individual turns is very small, the rotary movement of the offshoot 16 about the axis 28 is slow compared to the rotary movement of the offshoot about the axis 2o turns necessary wavelength band simultaneously with the transplantation. the branch 16 is through a second, the input spur gear 136 on the frame 14o (see Fig. I ₁ 3 and 4) by the roller pair 14 having drive 34 of the base plate around the axis 28'in rotation offset The rotation of the spur gear 136 takes place on the rigidly connected to the base plate 36

Toothed ring 142 transferred, whereby the base plate is set in urehung about the central axis of the container 12, since its axis 28 coincides with the central axis of the generally circular base plate 36. Because the offshoot 16 is mounted on the base plate 36, the rotation of the base plate about the axis 28 also causes the Rotation of the offshoot 16 about this axis 28, By rotating the offshoot 16 about the axis 28, the

stationary container 12 deposited.

The base plate 36 is supported by a bearing device 146 (see Fig. 7), which secures the base plate 36 against axial movement at the same time, rotatably mounted in the frame 14o. The bearing device has an inner ring 148 the axially arranged ring 152 of the base plate 36. An outer ring 156 of the bearing device 146 is on a Ring-shaped tires 16o fixed on the frame 14o by clamps 162. Rollers or balls 164 are formed out in a known manner in the rings 148 and 156 and allow the rotation of the base plate 36 relative to the Frame 14o. The rollers or balls 164 also secure in the In cooperation with the bearing rings 148 and 156, the base plate 36 prevents axial movements relative to the frame 14o. The base plate 36 has a radially extending over the rim 152 in a position between the frame 14o and the lower surface of the tire 16Ό formed angle 166 extending edge. The guiding of the plate 36 through the underside of the Tire 16o prevents upward movement of the base plate by the counterpressure of the belt in the container 12 when it is pressed in.

The first gear 24 (see Pig. 1, 3 and 4) offset the offshoot 16 about its axis 2ο in rotation »during this simultaneously performs a rotary movement about the central axis 28 of the container 12. To this end the first drive 24 has a rotatable on the frame 14o mounted and with a ring gear 172 on the outside of the annular part 174 in meshing spur gear 17o (see Pig. 4 and 7). The hung Can be rotated with the bearing 178 (Pig. 7) on the rim stored. The bearing 178 has the outer ring 182 and the Inner ring 18o, with lugs or balls 184 in between, on.

It should be noted that the drive 24 is relatively compact is, by the storage of the Hing 174 on the upper part 188 of the rim 152, and by the storage of the Wreath 152 on the helper 16o by means of the bearing 146 on the lower part 19o of the wreath. The compactness of the two drives 24 and 34 is still by the arrangement of the ring gear 142 of the drive 34 on the The outside of a web 194 formed between the bearings 146 and 178 enables

In addition to gears 17o and 172, the Drive 24 for the offshoot an intermediate gear 2oo, the

00981871229 " ^U "

is in engagement with a ring gear 2o4 formed on the inside of the ring 174 (see Pig. 3). The intermediate gear 2oo in turn drives a ring gear 2o6, on the outside of the wreath 6o around the Offshoot is arranged. Thus, the rotational movement of the ring 174 with respect to the base plate 36 drives the dual gear 2oo via the spur gear 17o and the ring gears 172 and 2o4 on ao that the offshoot 16 of the Zwisohenrad 2oo via the gear rim 2o6 that is firmly connected to the offshoot is driven. The intermediate gear 2oo is on an axis 21o mounted (see Pig. 3), which is movably guided in a guide 212 so that it is on the base plate 36 is to be shifted in order to keep the intermediate wheel 2oo bit engaged with the gear rims 2o6 and 2o4 when the eccentric 48 is rotated to the position of the offshoot 16 to be adjusted with respect to the base plate 36.

To coordinate the rotational movements of the offshoot 16 to the two axes 2o and 28 are the two drives 24 and 34 connected to a power source via a common transmission 250 (see FIGS. 1 and 8). The gearbox 25o has a main drive shaft 254 (see Fig. U), the connected to a power source via a suitable coupling

The bevel gear 26o for driving the gear 17ο of the motor is located on the main shaft 254

Transmission for the offshoot (see also FIG. 1) via the second bevel gear 262 (see FIG. 9). The gear wheel 136 of the power transmission for driving the base plate (Fig. 8) is through the gear set 264 with the Main shaft 254- connected. The gear set 264 has the gear pair 266, which produces the power transmission from the main shaft 254 to the auxiliary shaft 27o. The auxiliary shaft 27o is connected to the shaft 278 by the sonic drive formed by the worm and the worm wheel 276 (see FIGS. 8 and Io) the drive wheel 136 carries.

In certain circumstances the degree is desirable to change the offset of the tape turns against each other. For this purpose, the gear 25o is adjustable, so that the rotational speed of the deposit 16 about the axis 28 with respect to the rotational speed of the offshoot about the axis 2o is variable. By Changing the rotational speed of the offshoot 16 about the axis 28 while maintaining the rotational speed of the offshoot 16 about the axis 2o can be the displacement of the by the rotation of the offshoot 16 to the Change axis 2o formed turns. To this change in the rotational speed of the depository 16 to

To enable the axis 28, the gearbox 25o has one of a number of pairs of gears (of which only a pair 266 is shown) with different gear ratios that mesh with one another to be attached to shafts 254 and 27o. Through the Exchange of the gear pair shown in Fig. 8 and Io 28o and 282 against a (not shown) wheel

couple with a different transmission ratio, the speed of the Drive wheel 136 changed compared to that of the drive wheel 17o. By changing the speed of rotation of the drive wheel 136 with respect to that of the drive wheel 17o also changes the rotational speed of the offshoot 16 about the axis 28 relative to its rotation about the axis 2o, so that a change in the Measure takes place »in which the tape windings are offset from one another.

When the speed of rotation of the feeder changes 16 around the axis 28 by exchanging the pair of gears 28o and 282 is the conveying speed of the belt not changed by the pair of rollers 14 to such an extent that that the ratio between the conveying speed and the rotational movement of the pair of rollers by the Axis 28 remains the same. This is because the conveying speed of the belt by the relative speed

- 17 009818/1229

speed of the ring gear 2o4 in one direction opposite the base plate 36 rotating in the opposite direction is determined. When there is a change the ratio of the rotational speed of the pair of rollers 14 about the axis 28 for the conveyor speed of the tape, the turns 32 receive one of the in Pig. 2 shown essentially ring-shaped deviating: Shape.

TJm the shape of the turns 32 despite changes in the rotational speed of the pair of rollers 14 about the axis The drive spur gears are to be kept essentially the same Io8 and 114 interchangeable, so that the speed of the drive of the rollers 86 and 88 change leaves. A number of pairs of gears are provided for this purpose. Every pair of wheels is included basically the same as the pair of wheels Io8 and 114 In doing so, however, a different size ratio to the rollers 86 and 88 at different speeds to drive. By exchanging the gears Io8 and 114 for another pair with the desired one Gear ratio becomes when the gear ratio of gears 28o and 282 changes the speed of conveyance through the rollers 86 and 88 can be changed in such a way that the shape of the

In view of the above it can be seen that the device for depositing the strand material one Has offshoot 16 which is rotated by the power transmission devices 24 about a first axis 2ο Movement is set. The power transmission 24 has a drive wheel 17o, which drives the ring gears 172 and 2o4 to rotate with respect to the base plate 36. the Rotation of the ring gear 2o4 relative to the base plate causes the drive of the offshoot 16 via the intermediate gear 2oo and the ring gear 2o6. When the support 16 rotates relative to the base plate 36, the ring gear Io4 drives the pair of rollers 14 via the power transmission at. The pair of rollers 14 is rotatably mounted together with this on the depository 16, so that the belt in the stationary container 12 is deposited in a ring shape by the rotation of the pair of rollers with the offshoot 16 about the axis 2ο.

The hinges or turns of the ribbon are through the Rotational movement of the deposit with the pair of rollers 14 to the central axis 28 of the container 12 against each other offset. By changing the gear ratio

nissee of the gearbox 25o, the speed of rotation of the offshoot can be changed about the axis 28, in order to change the degree of offset of the turns with respect to one another. Sa a relatively high number of Turns of the tape are deposited in each layer of the container, and each turn is offset from the adjacent turn only by a small amount is, the base plate 36 is rotated at a relatively low speed about the axis 28, while the offshoot 16 is set in rotary motion by the drive 24 about the axis 2o.
