Device for loading a textile machine with individual conical coil tubes, including a supply container for the individual conical coil tubes having a bottom with an opening formed therein, a chute disposed below the opening formed in the bottom of the supply container, reciprocating slider means including a transport compartment with an open top and bottom formed therein for dispensing single coil tubes through the opening formed in the bottom of the supply container into the chute, a feed station disposed below the chute for receiving unsorted conical coil tubes, means for successively slipping individual conical coil tubes onto spindles or creel mandrels of a textile machine, and controlled coil tube turning means for passing on a conical coil tube presented in unsorted condition at the feed station to the slipping on means with tips sorted.

The invention relates to a device for loading a textile machine with 
individual conical coil tubes, consisting of 
(a) a supply container for the conical coil tubes, 
(b) a device for taking individual conical coil tubes from the supply 
container, and 
(c) a device for successively slipping individual conical coil tubes onto 
spindles or creel mandrels of the textile machine. 
The term "coil tube" relates to empty, wound or partially wound coil forms, 
but primarily to empty conical coil tubes for use in a spinning frame. 
The operating speed of the above mentioned devices is limited. In addition, 
they are disturbance-prone. It is an object of the invention to accelerate 
the loading of a textile machine with coil tubes and, especially, the 
loading of a spinning frame with empty conical coil tubes, and to make it 
operationally more reliable. This problem is solved by the invention by 
providing a device for dispensing a single coil tube through an opening in 
the bottom of the supply container into a chute by means of a 
reciprocating slider which has a transport compartment open at top and 
bottom, and a device for passing on a conical coil tube with tips sorted 
that was presented in unsorted condition at a feed station disposed at the 
lower end of the chute to the slipping-on device by means of a controlled 
coil tube turning device. One advantageous embodiment is wherein the coil 
tube turning device comprises a cross piece which is supported at a 
machine frame and can be swung back and forth by means of a controlled 
drive, a pair of gears which are rotatably supported on the cross piece 
and are formed of a sun wheel and a planetary gear which may, optionally, 
also have one or several intermediate gears, a locking device for locking 
the motion of the gears relative to the cross piece, a locking device for 
locking the sun wheel relative to the machine frame, and a coil tube 
holder connected to the planetary gear. 
Since the device according to the invention performs two motion cycles, 
namely, the controlled turning of the coil tubes and passing them on, 
simultaneously, wherein the coil tube is always held fast and not left to 
itself, the operating speed can be increased as compared to conventional 
devices, while the proneness to disturbances is reduced. 
In accordance with a further feature of the invention, the coil tube holder 
has a coil-tube suction nozzle subjected to underpressure. 
In accordance with an added feature of the invention, the cross piece has 
an underpressure canal which is connected to the coil-tube suction nozzle. 
In accordance with an additional feature of the invention, the cross piece 
has a hollow swing shaft which serves at the same time as the 
underpressure line. 
In accordance with still another feature of the invention, the feed station 
comprises a coil tube sensing station which has an operative connection to 
the locking device for locking the sun wheel to the machine frame. 
In accordance with still a further feature of the invention, the sensing 
device includes a controllable plunger, the position of which can be 
sensed by a feeler where the operational connection to the locking device 
starts at the feeler. 
In accordance with still an added feature of the invention, the plunger is 
connected to an alternating drive through a buffered or cushioned control 
rod. 
In accordance with still an additional feature of the invention, the coil 
tube holder cooperates with a controlled slip-on device which takes over 
and passes on the coil tube with tips sorted. 
In accordance with yet another feature of the invention, the slip-on device 
has two gripping hooks which can be controlled by a drive, and at which a 
counter holder controllable by stops is supported so that it can be swung 
between the gripping hooks. 
Advantageous embodiments of the supply container and the slider are 
provided as follows. 
In accordance with yet a further feature of the invention, the bottom 
opening of the supply container is at least twice as wide as the transport 
compartment, and the slider has mechanical disturbance elements which are 
in contact beside the transport compartment with the lower layer of coil 
tubes of the supply container. 
In accordance with yet an added feature of the invention, the disturbance 
elements are disposed in the form of a grid iron parallel to the 
longitudinal direction of the transport compartment. 
In accordance with yet an additional feature of the invention, the 
disturbance elements are in the form of round rods. 
In accordance with again another feature of the invention, the disturbance 
elements are in the form of rotatably supported cylinders. 
In accordance with again a further feature of the invention, the slider has 
an intermittent drive with an elastically resilient force transmission 
element. 
In accordance with again an added feature of the invention, the bottom of 
the supply container is inclined toward the bottom opening by an angle of 
eleven to fifteen degrees from the horizontal. 
In accordance with again an additional feature of the invention, the supply 
container is detachably and exchangeably supported on a frame carrying the 
slider. 
In accordance with another feature of the invention, the side walls of the 
supply container are trapezoidal, the wider side of the trapeze forming 
the upper edge. 
In accordance with a further feature of the invention, stacking surfaces 
are provided on the inside below the upper edge for the purpose of 
stacking similar containers on top of one another. 
The following advantages relate to the embodiment of the supply container 
according to the invention as a transport container. 
In accordance with an added feature of the invention, the supply container 
for the conical coil tubes is designed as an exchangeable transport 
container with a bottom opening that can be closed off by a separate 
slider. 
In accordance with an additional feature of the invention, the separate 
slider is supported in two slot-like cutouts in the side walls of the 
container, the separate slider protrudes from the two cutouts with one 
handle end at each side, and the material thickness of the separate slider 
including its handle ends is smaller than the width of the slot-like 
cutouts. 
In accordance with yet another feature of the invention, the transport 
container and separate slider are connected to each other by means of an 
easily detachable detent device. 
In accordance with yet a further feature of the invention, the bottom is 
inclined in the direction toward the bottom opening by an angle of 11 to 
15 degrees from the horizontal. 
Further advantageous embodiments of the overall loading device are 
described as follows 
In accordance with yet an added feature of the invention, the loading 
device is constructed so that it can be moved relative to the textile 
machine. 
In accordance with yet an additional feature of the invention, the loading 
device comprises at least one initiator for ascertaining the position of a 
spindle or a slip-on mandrel of the textile machine and has an operative 
connection to the drive of the coil-tube slip-on device. 
In accordance with again another feature of the invention, the device for 
taking individual coil tubes from the supply container, the device for 
passing-on a coil tube with tips sorted, and the coil tube slip-on device 
have a common drive motor. 
In accordance with a concomitant feature of the invention, the drive motor 
is a controllable stepping motor.

In FIGS. 1a and 1b can be seen the principal parts of which the device 
according to the invention consists, namely, the supply container 11 for 
the conical coil tubes; the device for taking individual conical coil 
tubes from the supply container 11, designed as a slider 28; the device 
125 for successively slipping individual conical coil tubes onto spindles 
126 of a spinning frame 127, not shown in all details; the device 75 to 
pass on, with tips sorted, a conical coil tube fed-in unsorted; the common 
drive 161 with the stepping motor 162; and the undercarriage 163 with the 
propulsion motor 164. 
As can be seen particularly in FIGS. 1a, 1b and 2, the machine frame 19 of 
the loading device according to the invention has a longitudinal wall 22, 
a partition 23, a lengthwise cross piece 24 and various transverse cross 
pieces. The upper edge of the longitudinal wall 22 and the longitudinal 
cross piece 24 serve as a track for the rollers 27 of a slider 28 which 
carries a control wedge 60. A feed station 61 is formed, as shown 
particularly in FIGS. 1a and 12, by two partitions 36, 37 of a chute 38 
and two hinged coil support levers 62, 63, arranged underneath the chute. 
The two coil support levers are connected to each other by a common shaft 
64. A flexible connection exists from the coil support lever 63 via a 
crank 65 to a strap 66, which is connected to a crank 67. The crank 67 is 
mounted at the end of a shaft 68, at the other end of which a crank 69 is 
likewise fastened. The crank 69 is linked to a control rod 70. A control 
roller 71 is mounted to the end of the control rod 70. The control rod 70 
is guided laterally by two antifriction bearings 72, 73. As soon as the 
control wedge 60 of the slider 28 runs onto the control roller 71, as 
shown in FIG. 12, the two coil support levers 62, 63 are swung under the 
chute 38 and catch a conical coil tube 74 which drops through the chute 
from above. 
According to FIGS. 3, 4 and 5, the supply container 11 designed as an 
exchangeable transport container has two slightly trapezoidal side walls 
9, 10 for the two longitudinal sides, two slightly trapezoidal side walls 
12, 13 for the two small sides and a bottom which consists of the two 
bottom parts 14 and 15. The bottom parts 14 and 15 are arranged 
symmetrically and have in the direction toward a bottom opening 16 an 
inclination of 11 degrees from the horizontal. Just above the bottom 
opening 16, slot-like cutouts 17 for receiving a separate slider 1 can be 
seen in the side walls 9 and 10. The slider 1 protrudes with a handle end 
1a, 1b from the two cutouts. The material thickness of the slider 1 
including its handle ends is smaller than the width "b" (slot width) of 
the slot-like cutout 17. 
The transport container and the slider are connected to each other by means 
of easily detachable detent devices 7, 8. Inside the transport container, 
conical coil tubes 20 are seen. These coil tubes lie parallel to the side 
walls 12, 13. Otherwise, the tips of the coil tubes are not oriented, 
i.e., it is left to chance whether the smaller cone end points toward the 
side wall 10 or toward the side wall 9. 
In detail, each of the two detent devices 7, 8 consists of a notch 5 
arranged in the handle end of the slider 1 and a detent pin 4 with a 
shoulder 4a. The detent pin 4 is guided in two brackets 3, 3a fastened to 
the side wall of the longitudinal side. A compression spring 2 loads the 
shoulder 4a of the detent pin 4 so that it sits in the notch 5 of the 
slider 1. 
The compression spring 2 is made only weak, so that the slider 1 can easily 
be pulled out and equally easily reinserted into the cutouts 17, which is 
achieved by bevels at the slider and the detent pins. 
Since the side walls are trapezoidal, the transport container is wider at 
the top than at the bottom, so that containers of the same kind can be 
nested. Stacking stops 21 arranged below the upper edge in the corners of 
the container prevent jamming and provide a defined stop. The new detent 
device provides an easily detachable form-fitting or positively 
force-transmitting locking and prevents unintentional pulling-out of the 
separate slider 1. The proposed inclination of the bottom facilitates 
emptying the transport container. Heretofore, the slider could be pulled 
out in known devices only to one side. Care always had to be taken that 
the handle end of slider came to lie on the operating side of the work 
station. It was a subtask of the invention to simplify the placement of 
the transport container at the work station, for instance, inasmuch as it 
is no longer necessary to see to it that the container points forward with 
a given front side and rearward with a given rear side. This objective was 
solved by the features of the slider 1 having cutouts 17 in the walls 9, 
10, having handles 1a,b protruding from the cutouts 17 and having a 
thickness, even at the handles, which is smaller than the width b of the 
cutouts 17. Since then, the slider which closes off the bottom opening can 
be pulled out toward two sides, it is no longer necessary to pay attention 
to a given position of the side walls in the placing and transporting of 
the containers. Working with such transport containers is thereby 
simplified. 
According to FIGS. 6 and 7, the slider 28, which serves as the device for 
taking individual conical coil tubes from the supply container 11, 
consists of a rectangular frame 29; a coil tube transport compartment 32 
which is located approximately in the middle, is open at the top and is 
formed by two partitions 30, 31; and several mechanical disturbance 
elements which are arranged in grid-iron-fashion parallel to the 
longitudinal direction of the transport compartment 32. The disturbance 
elements are cylinders 33, 34 which are arranged to the left and right of 
the transport compartment 32 and are supported rotatably in the frame 29, 
and three round rods 35 which have the same diameter as the cylinders. The 
disturbance elements are arranged side by side so that the coil tubes 20 
stored in the supply container 11 can neither drop through the gaps 
between the disturbance elements, nor can they be jammed in these gaps. 
However, the spacings between these disturbance elements must not be too 
small either, otherwise their effect is diminished. 
The drawing of FIG. 6 indicates that the bottom opening 16 of the supply 
container 11 is more than twice as wide as the transport compartment 32 of 
the slider 28. On the other hand, the chute 38 which is arranged between 
the longitudinal cross piece 24 and the longitudinal wall 22 and consists 
of the partitions 36 and 37, has the same width as the coil tube transport 
compartment 32. 
The slider 28 has an intermittent drive 39 with an elastically resilient 
force-transmission element 40. 
The drive 39 is connected to the common drive 161 shown in FIG. 1a and 
consists of a shaft 41 and a disc 42 fastened to the shaft, with a 
crankpin 43. The force-transmission element 40 consists of a telescoping 
tube 44 with a joint 45, 46 at each end, two tension springs 47, 48 and a 
compression spring which is located inside the telescoping tube 44. For 
each revolution of the shaft 41, the slider 28 goes back and forth once. 
The drawings of FIGS. 6 and 7 show the slider 28 in the extreme left-hand 
position. A coil tube 20a already lies in the transport compartment 32 on 
a plate 49 which connects the longitudinal wall 22 to the longitudinal 
cross piece 24 and adjoins the partition 36. As soon as the slider 28 now 
moves in the direction of the arrow 50, the coil tube 20a is taken along, 
goes into the chute 38 and drops down. In the meantime, the disturbance 
elements touch the lower layer of coils of the transport container 11 
resting on the angle-like cross pieces 25 and 26, conduct them into the 
gaps between the disturbance elements, lift them again, conduct them back 
into the gaps, and so forth. The motion of the lower layer of coils is 
also transmitted to the coil tubes above, so that the contents of the 
container are prevented from jamming or from forming bridges. It is seen 
that the two bottom parts 14 and 15 have horizontal angled-off portions 
51, 52 which at the same time prevent a coil tube taken up by the 
transport compartment 32 from escaping toward the top. 
The advantages obtained with the new device are, among others, that 
individual coil tubes can be taken out, without disturbance, at a rapid 
sequence. Should a foreign body get into the supply of coil tubes and 
block the slider, no secondary damage is done because the 
force-transmission element which drives the slider, is elastically 
resilient. 
As is shown particularly in FIG. 8, a coil tube turning device, designated 
as a whole with 75, is supported in the partition 23 as the device for 
passing-on, with the tips sorted, a coil tube fed-in unsorted. The coil 
tube turning device 75 consists of the following parts: 
In the partition 23 is supported by means of a cross piece 76 a controlled 
drive 77 which consists of a stepping motor, not shown, a disc 79 
connected to the shaft 78 of the stepping motor, a crankpin 80 fastened to 
the disc, a connecting rod 81 and a joint 82. From the joint 82, a 
connection is made via a crank 83 to a hollow swinging shaft 84, to which 
a cross piece 85 is fastened. A ball bearing 86 connected to the partition 
23 carries the swinging shaft 84 which serves at the same time as the 
underpressure line and makes it possible for the cross piece 85 to swing 
by an angle of 90 degrees. For greater clarity of presentation, the drive 
77 is shown swung by 90 degrees into the plane of the drawing in FIG. 8. 
Gears are rotatably supported on the cross piece 85, and specifically, a 
sun wheel 87, a planetary gear 88 and an intermediate gear 89. A pin 90 
connected to the cross piece 85 carries a ball bearing 91 which in turn 
carries the sun wheel 87. 
The intermediate gear 89 is supported on a pin 93 connected to the cross 
piece 85 with the interposition of a ball bearing 92. The planetary gear 
88 has a special support arrangement. On a hollow shaft 94, a needle 
bearing 95 is arranged which carries the planetary gear 88. A coil tube 
holder 96 is connected to the planetary gear 88. It consists of a tube 97 
with a coil tube suction nozzle 98. 
As can be seen particularly from FIGS. 8 and 17, the pin 90 carries a ring 
99. Over the ring 99, there is arranged, with a small spacing, a further 
ring 100 which is connected to the sun wheel 87 by four screws 101 by 
means of a bushing 102. The ring 100 carries a locking device 103 for 
blocking the relative motion of the gears against the cross piece 85. The 
locking device 103 consists of a ball 104, a compression spring 105 and a 
set screw 106. In the locked position, the ball 104 is detented in one of 
the two depressions 107, 108 in the ring 99. The two depressions are 
relatively shifted 90 degrees at the circumference of the ring 99. The 
depression 107 serves as a detent in the coil tube pickup position and the 
depression 108 as a detent in the coil tube discharge position of the coil 
tube turning device 75. 
The herein aforementioned lock can be cancelled, specifically, by a further 
locking device 109 for locking the sun wheel 87 against the machine frame 
19. This locking device is shown specifically in FIG. 12. It consists of a 
pawl 112 which can be controlled by a control lever 110, using a control 
rod 111. The ring 100 has a notch 113, in which the pawl 112 can detent in 
the respective coil tube pickup position of the coil tube turning device 
75. The control for the detent will be discussed later on. 
The drawings of FIG. 8 indicates that the cross piece 85 has an 
underpressure canal 114 which is connected to the coil tube suction nozzle 
98. Therefore, a connection exists from the suction nozzle 98 via the 
hollow shaft 94, the underpressure canal 114 and the hollow swinging shaft 
84 to an underpressure source, not specifically shown. 
As can be seen particularly from the drawing of FIG. 12, the feed station 
61 has a coil tube sensing device 115, from which an operative connection 
116 leads to the locking device 109 for locking the sun wheel 87 against 
the machine frame 19. The sensing device 115 consists of a controllable 
plunger 117, the position of which can be sensed by a feeler 118; the 
operative connection 116 to the locking device 109 starts from the feeler 
118. In the present embodiment example, the feeler 118 consists of a 
microswitch and the operative connection 116 is in the form of an 
electrical line. The plunger 117 is connected by means of a rocker arm 119 
to an alternating drive 121 via a buffered control rod 120. The latter has 
a telescoping tube 122, in which a buffer spring 123 is provided. The 
plunger 117 extends with its end through the partition 37 into the chute 
38 at the height of the waiting coil tube 74. The drawings of FIGS. 10 and 
11, show that the coil tube sensing device 115 is mounted in a housing 124 
attached to the partition 37. 
The coil tube holder 96, and in a broader sense therefore also the coil 
tube turning device 75, cooperates with a device 125 for successively 
slipping individual conical coil tubes onto the spindles 127, which is 
designed as a controlled mechanical gripper which takes over and passes on 
the already tip-sorted coil tube 74 from the coil tube turning device 75 
or its coil tube holder 96. 
The slipping-on device 125, as shown in FIG. 9, has two gripping hooks 129, 
130, which can be controlled by a drive 128 and at which a counter holder 
133 controllable by stops 131, 132 is supported so that it can be swung 
between the gripping hooks 129,130. The latter are fastened to a vertical 
shaft 134. At the bottom, the shaft 134 is supported in a bracket 135 
fastened to the partition 23 and at the top, to a bearing 136 fastened to 
the longitudinal cross piece 24. To the lower end of the shaft 134, a 
crank 137 is mounted which is connected by a connecting rod 138 to the 
drive 128. The drive 128 consists of a shaft 139, on which a disc is 
mounted which carries a crankpin 141. The shaft 139 is connected to the 
common drive 161 (FIG. 1a). 
The gripping hooks 129,130 serve at the same time as support for a vertical 
shaft 142, to which the counter holder 133 is fastened. A coiled torsion 
spring 143 ensures that the counter holder 133 always tends to swing 
between the gripping hooks 129, 130. To the upper end of the shaft 142, 
the lever-like stop 131 is fastened which carries at its end a roller 144. 
The shaft 142 also has a crank 145 which is connected via a connecting rod 
146 to a further crank 147 which carries the stop 132 in the form of an 
adjusting screw. The crank 147 is supported in a bracket 148 fastened to 
the partition 23. The herein aforementioned linkage is driven by the 
previously mentioned stepping motor. To limit the swing travel of the 
counter holder 133, the shaft 142 carries at its lower end a stop lever 
149 with a roller 150. A table 172 serves for guiding the coil tube during 
the swinging motion or at least for preventing it from sliding down too 
far. 
In the description which now follows of an operating cycle, a starting 
position according to FIG. 9 is assumed. The slipping-on device 125 had 
just before pulled a conical coil tube 74a off the coil tube suction 
nozzle 98, had been swung to the left and will drop the coil tube at the 
next instant. In the meantime, the cross piece 85 of the coil tube turning 
device 75 swings in the direction of the arrow 151 upward, i.e., 
counterclockwise to fetch the conical coil tube 74 which is already 
waiting at the feeding station 61. 
In the meantime, the coil tube sensing device 115 according to FIG. 12 goes 
into action as follows: 
The alternating drive 121 swings from the position shown 45 degrees in the 
direction of the arrow 152 and back. In the course of the swing motion, 
the plunger 117 makes contact with the coil tube 74. If it makes contact 
with the smaller end of the cone (with the plunger being indicated by 
dot-dash lines), then the rocker 119 switches on the sensor 118 and a 
current flows through the operative connection 116 to an electromagnetic 
actuator 153 operating the control lever 110. This makes the pawl 112 of 
the locking device 109 detent at the instant when the cross piece 85 is 
horizontal and the coil tube suction nozzle 98 is in the coil tube pickup 
position, as shown in FIG. 10. If the thinner end of the conical coil tube 
74 were actually in front of the plunger 117, then the sun wheel 87 would 
be held by the pawl 112 when the cross piece 85 swings back against the 
direction of the arrow 151 as long as the swing motion of the cross piece 
85 lasts, because the pawl 112 is self-locking. Since in the present 
embodiment example, the sun wheel 87 has twice as many teeth as the 
planetary gear 88 and an intermediate gear 89 is interposed, the coil tube 
suction nozzle 98 would rotate with the sucked-up coil tube 90 degrees in 
the opposite direction when the cross piece 85 swings back, i.e., in the 
direction of the arrow 151 if the cross piece 85 also executes a 90-degree 
rotation but against the direction of the arrow 151, while at the same 
time the locking device 103 disengages since it operates only with 
tensional connection. Thereby, the thinner end of the cone, which had 
previously been sensed by the coil tube sensing device 115, is on top at 
the end of the swing motion, as desired, and the thicker end would be at 
the bottom. 
In the present embodiment example, however, it is provided that the thicker 
end of the cone of the coil tube 74 lies in front of the plunger 117, as 
shown particularly in FIG. 13. In that case, the rocker 119 has no 
occasion during the sensing process to actuate the feeler 118. The locking 
device 109 for locking the sun wheel 87 thus does not go into action in 
this embodiment example and the pawl 112 does not snap into the notch 113. 
Instead, the locking device 103 for blocking the relative motion of the 
gears against the cross piece remains detented and therefore, in 
operation. Accordingly, the following further procedure is obtained, 
starting from the position as per FIG. 10: 
The suction air effective in the coil tube suction nozzle 98 sucks up the 
conical coil tube 74 and the drive 161 moves the slider 28 in the 
direction of the arrow 154 according to FIG. 12; a tension spring 155 
pulling the strap 66 in the direction of the arrow 156 because the control 
roller 71 slides off the control wedge 60. As a result, the coil support 
levers 62 and 63 are hinged down. In the meantime, the slider 28 can take 
another coil tube from the supply container 11. 
At the same time, the drive 77 is set in motion. The disc 79 rotates in the 
direction of the arrow 157 until the cross piece 85 occupies the position 
shown in FIG. 8, i.e., is vertical. According to FIG. 11, the cross piece 
85 has not yet quite completed the swing motion against the direction of 
the arrow 151. 
In the meantime, also the drive 128 becomes operative. The disc 140 make 
one-half revolution in the direction of the arrow 158 from the coil tube 
discharge position shown in FIG. 16. At the end of this motion, the 
slipping-on device 125 is in the coil tube pickup position as per FIG. 14. 
The stop 131 has run against a stop surface 159 and has swung the counter 
holder 133 back. The illustration of FIG. 11 shows that the slipping-on 
device 125 is already open before the coil tube turning device 75 has 
completed its motion. As soon as the coil tube 74 has been brought into 
the vertical position, as shown in FIG. 14, the disc 140 continues to 
rotate for half a revolution in the direction of the arrow 158. An 
intermediate position of this motion cycle is shown in FIG. 15. There, the 
coil tube is already clamped between the gripping hooks 129, 130 on the 
one side and the counter holder 133 on the other side. At the end of the 
motion of the disc 140, the slipping-on device 125 again assumes a 
position according to FIG. 16. The latter figure shows that the stop 132 
has made contact with the partition 23 and the counter holder 133 has 
therefore been lifted off the coil tube in the direction of the arrow 160. 
The coil tube is then vertically above the spindle 126 of the spinning 
frame 127 and drops down onto the spindle. 
The slipping-on device 125 remains in the end position shown in FIG. 16 
until the initiator 165 shown in the drawings of FIGS. 1a and 1b has 
ascertained the approach of the next-following spindle 126a. Then it 
delivers via the operative connection 166 a start pulse to the drive 161, 
whereupon the motion cycle shown and described is repeated. 
The coil tube turning device 75 is swung back already before the instant 
when the slipping-on device 125 has reached the position according to FIG. 
15, to fetch the next-following coil tube. Since the slider 28 is moved in 
synchronism with the devices 75 and 125, coil tubes can be slipped onto 
the spindles of the spinning frame sequentially in this manner, while the 
complete loading device travels along the spinning frame 127 in the 
direction of the arrow 169 on the tracks 167, 168 without stopping. 
FIG. 2 shows once more the final instant of passing-on the coil tube 74. It 
is clearly seen in FIG. 2 that the coil tube holder 96 has already been 
swung back far and can receive the next-following coil tube already 
shortly thereafter. It goes without saying that the motion cycles 
described must merge into one another. This calls for a well-tuned control 
system, which can be realized in a manner known per se by gears, crank 
drives or cams very simply. The drive 161 equipped with the electric 
stepping motor 162 has been found practical as a common drive element. 
The invention is not limited to the embodiment example shown and described. 
The operative connection 116 can alternatively also be designed as a 
mechanical operative connection. This would have the advantage that all 
motion cycles can be started up from the central drive 161. 
The travel velocity and the operating speed are matched to each other. The 
loading cycle is timewise adjusted always to a somewhat shorter 
theoretical value that the travel time required for the travel from 
spindle to spindle. A new loading operation is initiated only when the 
next spindle to be loaded has approached the initiator, so that in 
practice, the loading cycle and the travel cycle agree. Thus, if the 
loading device comes into the vicinity of a spindle of the spinning frame 
which is ready to receive one, it already has a coil tube ready for 
slipping-on. 
The roller 171 which is visible in FIGS. 1a and 1b and is supported at an 
arm 170, has the purpose of pushing the conical coil tubes, which have 
already been slipped on, further down onto the spindles to a predetermined 
dimension. This can be accomplished simply by letting the roller roll off, 
or by swing motions of the arm 170. The further drives 39, 77, 121, 128 
are centrally controlled by means of the central drive 161. Thus, all 
motions are tuned to each other. The tuning of the motion cycles is 
performed once empirically and then applies to other devices of the same 
kind. Gears, cams and control levers are known as adjusting elements for 
motion cycles, to name only a few elements.
