INT CL 3 B 65 H 49/00 DO 1 H 1/10 11 B 65 H 49/10 49/14 ( 52) Index at Acceptance D 1 J E D 1 F X ( 72) Inventors: ALOYS GREIVE ALOYS HORTSMANN ( 54) SPINNING MACHINES ( 71) We, HAMEL Gmb H, ZWIRNMASCHINEN of Dahlweg 102, 44 Munster, Westphalia, Germany, a Company organised under the Laws of Germany; do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:
The invention relates to a two-for-one up-twisting yarn doubling machine comprising a base frame, spindle disposed rotatably on the base frame, a driving whorl for the spindle, a feed bobbin mounted on the spindle and a pivotable overhead creel from which a second yarn is drawn for doubling with the first yarn.
A creel for textile machine has been proposed comprising a bobbin holder swingingly suspended on at least one supporting arm and one balance arm both mounted pivotally on the machine frame, a hydraulic unit connected to said supporting arm by means of one of a pair of arms both rigid with the supporting arm, the second of which is engageable with a latch for holding said supporting arm in its normal working position, a slide valve for controlling the hydraulic unit, and means operatively connecting the slide valve and the latch.
The access to the bobbins is however under certain circumstances difficult for operating staff in particular when several bobbins per spindle are disposed above one another in a vertical direction and the upper bobbins lie outside the convenient working height of the operating staff In addition the operating staff, for example, when changing a bobbin must walk in the direct vicinity of the rotating bobbins and the running yarn so that there is the possibility of disturbing the twisting or spinning operation as well as danger to the staff.
According to the invention a two-for-one up-twisting doubling machine comprises a base frame, a hollow spindle mounted vertically on the base frame, a driving whorl for the spindle, a feed bobbin mounted on the spindle, a yarn guide located above the spindle, a first yarn passing upwards from the feed bobbin upwards to the yarn guide, a yarn storage disc on the spindle below the bobbin, the bobbin being enclosed by a stationary can surrounded by a balloon limiting cover, and an overhead pivotable creel mounted above the spindle, a second yarn being drawn downwards from the creel, a vertical tube through which the second yarn passes to the yarn storage disc from which it passes upwards between the can and the balloon limiting cover to the yarn guide where the two yarns are doubled together, a winding bobbin onto which the doubled yarn is wound and means for driving the winding bobbin.
The invention will be further described with reference to the accompanying drawings.
Figure 1 shows a two-for-one up-twisting doubling machine according to the invention in a particularly diagrammatic section in a plane at right angles to the longitudinal direction of the machine.
Figure 2 is an enlarged view of a pivoting device in the raised position of a creel corresponding to the right hand side of Figure 1, Figure 3 is an enlarged representation of the pivoting device on the creel in the lowered position corresponding to the left 1 592 239 1 592 239 hand side of Figure 1; Figure 4 is a plan view of the creel in a direction at right angles to the longitudinal direction of the machine, S Figure 5 is a second embodiment of the creel receiving a plurality bobbins and; Figure 6 is a third embodiment of the creel.
In Figure 1 there is generally indicated by 10 a machine frame of a two-for-one uptwisting doubling machine with a lower frame 12 and a central wall 14, mounted on the lower frame 12 Longitudinally of the base frame of the machine and symmetrical with respect to the centred wall 14 of the frame are disposed a plurality of twisting heads two of which are shown in Figure 1.
Each of the twisting heads 16 comprises, a hollow vertical spindle 30 with a spindle rotor 18 rotatably mounted on the lower frame 12 on which spindle rotor a first bobbin 20 is placed The bobbin 20 is surrounded by a stationary protecting can 22 which in its turn is enclosed by a balloon limiting cover 24 The spindle rotors 18 for the spindles 30 are driven by a driving belt 26, driven by a motor, not shown, the driving belt being pressed by rollers 28 against a whorl on the spindle 30 of the respective spindle rotor 18 Above each spindle 30 there is disposed a winding device generally indicated by 34 on the central wall 14 of the frame and on a cross bearer 32 running transversely of the machine The winding device comprises a winding cylinder 36 which is driven through a driving shaft 38, running parallel to the longitudinal direction of the machine and driving a winding bobbin 40 engaging the periphery of the cylinder 36 The winding bobbin 40 is mounted on a bobbin carrier frame 42 which is pivotably mounted about an axle 46 running parallel to the longitudinal direction of the machine on a central support 44 extending upwardly as an extension of the frame wall 14.
The bobbin carrier frame 42 may be raised from the winding cylinder 36 by means of a handle 48 in order, to be able to doff a full bobbin 40 On the outer end of the cross bearer 32 a fast running roller 50 is driven by a shaft 52 running parallel to the longitudinal direction of the machine Between the fast running roller 50 and the winding cylinder 36 is a yarn guide 51.
With the up-twisting machine known per se as described so far for spinning and twisting a yarn doubling apparatus is added without increasing the floor space.
In order to convert the machine to a doubling frame a first yarn 54 is drawn off upwards from a bobbin 20 through a known yarn brake 56 to a yarn guide 61.
A second yarn 58 from a creel mounted above the two-for-one machine passes downwards to a storage disc 60 for doubling with the first yarn 54 from the bobbin 20.
The storage disc 60 is mounted on the spindle 30 below the bobbin 20 The yarn 58 leaves the storage disc 60 and passes upwards between the can 22 and the balloon limiting cover 24 to the yarn guide 61 mounted above the spindle 30 and doubles up with the yarn 54 from the bobbin 20.
Both yarns are therefore equally tensioned and the twisted yarn 62 is passed over the roller 50 and is wound onto the bobbin The second yarn 58 rotates, upon rotation of the spindle 18, around the first yarn coming from the feed bobbin 20 The doubled yarn is wound onto the bobbin 40 and may have the same structure as a yarn for example, with Z turns in the single yarn and S turns in the doubled yarn.
Whilst the feed bobbins for the second yarn were hitherto placed on a frame set up next to the base frame of the machine, with the up-twisting machine according to the invention a creel 64 is provided which is pivotally mounted on a frame 66 supported above the base frame of the machine.
The creel 64 and the pivoting frame 66 will be hereinbefore described more precisely.
The creel 64 comprises a creel frame 68 having a frame member 70 arranged at an angle a to a second frame member 72 The angle may be substantially 1200 Both frame members 70 and 72 are formed, by two box profiles welded together at their junction.
At the free-end of the frame members a bobbin holder 74 is provided which has an arm 76 with an arm 78 at right angles thereto which carries a pin 80 the axis of which lies parallel to the plane of the frame 66 A pin is similarly mounted on the free end of the member 70 The arms 76 of the bobbin holders 74 are arranged as above described on the respective members 70 and 72 pivotable about an axis lying in the plane of the frame and running at right angles to the respective frame members 70, 72 so that the bobbin holder 74 can be pivoted between a first position in which the axis of the pin 80 lies in the plane of the frame to a second position in which the pin axis lies outside the plane of the frame It would of course also be possible to design the bobbin holders so that they are pivoted about an axis running parallel to the longitudinal direction of the actual frame member The placing of bobbins 82 and 84 on the pins 80 of the bobbin holder 74 is facilitated as the frame 66 can be pivoted from the position shown on the right of Figure 1 to that shown on the left.
The bobbin holder 74 may be locked in any desired manner in the operating position as shown in Figures 1 and 4 in which the axis of the pin lies in the plane of the frame As an example of such a locking in Figure 2 a catch 1 592 239 device is shown having a semi-spherical recess 86 in the arms 76 lying on the respective frame members 70 and 72 and a ball catch 88, which is guided into a bore 90 in the respective frame members 70 and 72 and is clamped by means of a compression spring 92 in the direction of the semispherical recess 86.
On a support arm 94 (Figure 4) firmly connected to the arms 70 and 72 of the creel frame 68 there is arranged a yarn guide device indicated generally by 96 for the second yarn 58 drawn off from the feed bobbin 82 or 84 The supporting arm 94 does not run in the plane of the frame but is inclined oppositely to this so that it does not obstruct the bobbins 82 and 84 (Figure 4) A thread guide device 96 has an arm 98 reaching from the free end of the supporting arms 94 to the plane of the frame in the free end of which are disposed a first yarn guide As can be seen from Figure 1 the first yarn guide 100 is mounted approximately at a point of the angle bisectors of the angle a at which extensions of the axes of the pins 80 would meet Thus the conditions for yarn 58 running off remain the same independenlty of whether it is drawn off from the bobbin 82 or the bobbin 84.
Adjacent to the free end of the supporting arm 94 is arranged a further yarn guide 102 on the yarn guide device 96 by means of which the yarn 58 is guided via the yarn guide 100 substantially at right angles to the plane of the frame The yarn is guided in the direction of the lower end of the spindle via an adjustable yarn brake 104 (Figure 4).
The creel 64 is mounted by means of the pivoting device 66 on a longitudinal bearer 106 (Figure 3) resting on the central support 44 The longitudinal bearer 106 is thus supported in the region of the cross bearers 32 by means of supporting rods 108 placed on the cross bearer 32 The pivoting device 66 can be pivoted so that the creel whilst maintaining the spatial direction of its parts between the first operating position shown in the right side of Figure 1 and the second operating position or bobbin changing position shown on the left side of Figure 1.
For this purpose the pivoting device 66 comprises a joint parallelogram in which two sides thereof are formed by two pivot levers 110 and 112 which are hinged about pivot pins 116 and 118, running in a longitudinal direction of the machine, on a cross flange 114 firmly connected to the longitudinal bearer 106 The free ends of the pivot levers 110 and 112 are articularly connected by means of a joint lever 120 at further joint points 122 and 124 respectively whereby the connecting line of the joint points 122 and 124 run parallel to the connecting line through the pins 116 and 118 The joint lever 120 is connected by an extension to the upper end of the substantially vertical frame member 70 of the creel frame 68, for example by welding As can easily be seen from Figures 1 to 3 the joint lever 120 upon pivoting of the pivot levers 110 and 112 maintains its direction in space and thus the orientation of the creel frame 68 upon pivoting the creel 64 is retained The pivot lever 110 is formed of channel or U section with side legs 126 and a cross bridge piece 128 shown in section in Figure 2 The axes 122 and 116 run perpendicularly to the legs 126.
The pivoting device 66 comprises furthermore a traction spring arrangement 130 which serves to bring back the creel 64 into its upper position or at least support the pivoting up of the creel 64 and hold this in its upper position The traction spring arrangement 130 comprises two traction springs 132, which are guided in protective tubes 134 The upper end of the traction spring arrangement 130 in Figure 2 is hinged on the legs 126 on a pin 136 running parallel to the longitudinal direction of the machine and the opposite end of the traction spring arrangement 130 is pivoted on the cross flange 114 by means of a screw 138 Thus the pin 136 and screw 138 respectively are so selected that the traction springs 132 upon pivoting of the pivot levers 110 and 112 from the position shown in Figure 2, to the position shown in Figure 3 are expanded as shown by a comparison of these figures As can be seen in particular from Figure 2, the screw 138 of the spring arrangement 130 on the cross flange 114 is relatively close to the connecting line between the axes 116 and 122 of the pivot lever 110 Thus in the upper pivoting position of the pivoting device 66 shown in Figure 2 the torque exercised by the traction spring arrangement on the pivoting lever 110 in respect of its axis 116 is relatively small so that even with a large spring force of the traction springs 132 the creel 64 does not strike heavily and its upper end position is determined by the contact of the lever 110 against the cross flange 114 with a damping strip 140 thereon made of an elastic material to dampen the shock The damping may of course also be effected in any other desired manner.
In order that the operator does not have to hold the creel 64 in the lower bobbin changing position against the spring tension of the traction spring arrangement 130 and has both hands free a locking device is provided This comprises a holding pawl 142 which is mounted pivotable about a pin 144 running cross-wise of the channel legs 126 of the pivot lever 110 and held tensioned in its locking position by a spring stirrup 146 with one end 143 supported on the inside of the cross bridge piece 128 of the pivot lever 110 and with its other end 150 engaging around 4 1 592 239 4 the holding pawl 142 The position of the holding paw’142 is so selected that upon pivoting the pivoting device from the position shown in Figure 2 into the position shown in Figure 3 the joint pin forming the joint axis 124 approaches the holding pawl 142 and in the position shown in Figure 3 catches under the nose piece 152 of the holding pawl 142 Thus the pivoting device 66 and with it the creel 64 is locked in the lower position.
The release of the locking means is effected by an operating lever 154 (Figure 3) mounted on the holding pawl 142 lying outside the channel of the pivoting lever 110 and pivoted to release the bolt 124 from the nose piece 152 of the holding pawl 142 For protection and for accurate guiding of the second yarn 58 on its way from the creel 64 to the lower end of the spindle rotor 18 a yarn guiding device indicated generally by 158 is used It comprises a yarn guide tube extending substantially vertically which is secured by holding means 158 and 162 on the balloon limiting cover 24 and on the machine base frame respectively and the upper inlet end of which lies approximately level with the yarn guide roller 50 of the winding device 34 and the lower outlet end of which is located approximately level with the lower end of the spindle rotor 18 On the upper and on the lower end of the yarn guide tube 160 there is arranged respectively a yarn guide 164 and 166 For easier threading in of the second yarn 58 into the yarn guide tube 160 there is in the wall of the tube a longitudinal slit 168 extending over the whole length The yarn guide tube 160, considered transversely of the longitudinal direction of the machine, is disposed between two spindles 16 adjacent one another such that the second yarn 58 runs from the yarn guide device 96 in a plane perpendicular to the longitudinal direction of the machine through the yarn brake 104 and the thread guide tube 160 Thus the yarn 58 runs in a plane parallel to the pivoting plane of the creel independently of the actual pivoting position of the creel 64.
The length of the yarn 58 passing between the yarn brake 104 of the yarn guiding device 96 and the yarn guide 164 on the upper end of the yarn guide tube 160 due to the pivoting of the creel 64 is practically not influenced The yarn 56 also never passes in front of the winding device 34 so that it cannot obstruct the working of the operating staff on the winding apparatus Thus conditions are provided so that the exchanging of the feed bobbins 82 and 84 on the creel 64 is effected during the operation of the up-twisting machine.
For the setting in operation of the uptwisting machine for the carrying out of the cabling process the following steps are necessary: The creel 64 is pivoted down form its upper operating position into the lower bobbin changing position so that the creel frame 68 lies at the working height of the operating staff The feed bobbins 82 and 70 84 are placed on the creel pins 80 The start of the yarn of one feed bobbin, for example the feed bobbin 82, is joined to the end of the yarn of the second feed bobbin 84 The start of the yarn of the feed bobbin 84 is 75 guided via the yarn guides 100, 102, (Figure 4) of the yarn guiding device 96 and via the adjustable yarn brake 104 to the yarn guide 164 on the upper end of the yarn guide tube and inserted through the slit 168 into the 80 yarn guide tube 160, and guided via the yarn guide 166 on the lower end of the yarn guide tube 160, to an adjustable yarn brake 170 close to the yarn guide 166 and a yarn guide 172 close to the lower end of the spindle 85 rotor 18 The yarn is threaded into the hollow axle of the spindle rotor 18 The further path of the yarn 58 has already been described above After the releasing of the holding pawl 142 the creel 64 returns under 90 the action of the traction spring arrangement 130 into its upper position After the drawing off of the yarn material from the feed bobbin 84 because of the joining of the yarn ends the yarn 58 is automatically drawn 95 off from the feed bobbin 82, without having to interrupt the operation of the up-twisting machine and the creel 64 can again be pivoted into its lower position The bobbin holder 74 is pivoted out from the plane of 100 the frame, the old bobbin carrier 174 is removed from the pin 80 and a new feed bobbin 84 applied The bobbin holder 74 is turned back into its initial position so that the ball 88 is caught in the recess 86 The 105 start of the feed bobbin 84 is joined to the end of the yarn of the bobbin 82 and the creel 64 after the release of the holding pawl 142 is again pivoted back into its upper position As can be seen from the foregoing 110 description by means of the creel, a space saving arrangement of the feed bobbins is provided for the second yarn coming from the creel which render possible a convenient changing of bobbins without interruption of 115 ‘ the operation of the up-twisting machine.
The creel in conjunction with an uptwisting machine has been described in the foregoing.
The advantage achieved with the creels 120 with reference to Figure 5 and 6 is clear In a narrow space a plurality of feed bobbins can be so arranged that all single yarns have substantially the same path In the operating position of the creel shown on the right side 125 of Figure 6 the operating staff has free access to the delivery mechanism and the twisting spindles For the changing of the feed bobbins or for carrying out any servicing work on the feed bobbins the creel is 130 1 592 239 1 592 239 pivoted down into the bobbin changing position shown on the left side of Figure 6 and is locked in this position The operator can now readily attend to all feed bobbins.
This would be possible, for example, with an arrangement for five feed bobbins vertically above one another on a rigid creel as the uppermost feed bobbins can only to be reached with difficulty by an operator Due to the fact that the pin axes of the creels each pivoting the creel frame, substantially maintain their position in the course of the passage of the yarn from the creel and the delivery mechanism is hardly effected so that the pivoting of the creel can be carried out during the twisting operation.
