Technical Field
[0001] This disclosure relates to the field of textile machinery and, in particular to a
single doffing device and a single doffing control method and control apparatus.
Background
[0002] A semi-automatic rotor spinning machine generally includes multiple spinning machine
workstations. The spinning machine workstation may include a spinning mechanism and
a winding mechanism, the spinning mechanism being used to produce yarns, and the winding
mechanism winding the yarns; a yarn take-off device may also be arranged between the
spinning mechanism and the winding mechanism, and it may guide the yarns by using
a yarn take-off roller and a pressure roller, so that the winding mechanism may wind
the yarns efficiently. The winding mechanism generally cross-winds the yarns around
a tube to form a bobbin or package of a certain size.
[0003] It should be noted that the above description of the background is merely provided
for clear and complete explanation of this disclosure and for easy understanding by
those skilled in the art. And it should not be understood that the above technical
solution is known to those skilled in the art as it is described in the background
of this disclosure.
Summary
[0004] However, it was found by the inventors that artificial intervene is still needed
in existing semi-automatic rotor spinning machines, for example, tubes need to be
artificially replaced after a yarn bobbin is completed. Hence, maintenance cost is
still relatively high, security is relative low, and operational efficiency is not
high.
[0005] In order to solve at least one of the above problems or other similar problems, embodiments
of this disclosure provide a single doffing device and a single doffing control method
and control apparatus, with an expectation of eliminating or avoiding artificial intervene,
lowering maintenance cost, and improving security and operational efficiency.
[0006] According to an aspect of the embodiments of this disclosure, there is provided a
single doffing device, including:
a spinning machine workstation having a spinning mechanism for producing a yarn and
a winding mechanism for winding the yarn, wherein the winding mechanism is provided
with a replaceable tube around which the yarns are wound;
a control apparatus configured to, when the yarn is wound into a yarn bobbin of a
predetermined size on a replaceable tube on the winding mechanism, transmit control
information for instructing to replace the yarn bobbin on the winding mechanism; and
a tube replacement apparatus storing one or more tube(s) therein and configured to
replace the yarn bobbin on the winding mechanism by using one of the stored tubes
upon receipt of the control information.
[0007] Hence, the yarn bobbin is replaced with an empty tube automatically after the yarn
winding is completed by replacing the yarn bobbin on the winding mechanism with the
tube stored in the tube replacement apparatus, thereby eliminating or avoiding artificial
intervene, lowering maintenance cost, and improving security and operational efficiency.
[0008] In some embodiments, the control apparatus transmits the control information to the
tube replacement apparatus in a case where a yarn length of the yarn bobbin reaches
a predetermined length, or a weight of the yarn bobbin reaches a predetermined weight,
or a diameter of the yarn bobbin reaches a predetermined diameter, or a length of
the yarn bobbin reaches a predetermined length.
[0009] Hence, a time for replacement may further be controlled exactly by the control apparatus,
and operational efficiency may be improved.
[0010] In some embodiments, the control apparatus transmits a control instruction to stop
winding to the spinning machine workstation and causes the yarn bobbin to be ejected
from the winding mechanism to a conveyor belt in a case where a yarn length of the
yarn bobbin reaches a predetermined length, or a weight of the yarn bobbin reaches
a predetermined weight, or a diameter of the yarn bobbin reaches a predetermined diameter,
or a length of the yarn bobbin reaches a predetermined length.
[0011] Hence, the time for replacement may further be controlled exactly by the control
apparatus, and operational efficiency may be improved.
[0012] In some embodiments, the tube replacement apparatus pushes out the one of stored
tubes at an introduction position and configures the tubes on the winding mechanism
after the yarn bobbin on the winding mechanism is ejected.
[0013] Hence, instructed by the control apparatus, the tube replacement apparatus and the
winding mechanism operate in parallel, the time for replacement may further be controlled
exactly by the control apparatus, and operational efficiency may be improved.
[0014] In some embodiments, the tube replacement apparatus is moved from a loading position
to an introduction position upon receiving a control instruction, or, the tube replacement
apparatus is moved from a loading position to an introduction position during spinning,
or, the tube replacement apparatus is moved from a loading position to an introduction
position after storing the tube(s), and remains at the introduction position when
the tube(s) exist(s) in the tube replacement apparatus.
[0015] Hence, the tube replacement apparatus may reach the introduction position (standby
position) before the spinning process is suspended, thereby saving time for replacing
the tubes, further controlling exactly the time for replacing the tubes, and improving
operational efficiency.
[0016] In some embodiments, the control apparatus detects whether the winding mechanism
is configured with the tube, and transmits a control instruction for starting producing
and winding the yarn to the spinning machine workstation in a case where the tube
is correctly configured on the winding mechanism.
[0017] Hence, with the detection by the control apparatus, the time for operation again
of the winding mechanism may be exactly determined, and security and operational efficiency
may further be improved.
[0018] In some embodiments, in the case where the tube is correctly configured on the winding
mechanism, the control apparatus further transmits a control instruction to the tube
replacement apparatus to cause the tube replacement apparatus to be moved from the
introduction position back to a loading position or a standby position.
[0019] Hence, with the detection by the control apparatus, the time for standby and introduction
of the tube replacement apparatus may be exactly determined, and security and operational
efficiency may further be improved. Moreover, after the tube replacement apparatus
is moved back to the loading position or the standby position, maintenance and loading
of the tubes may be better conducted.
[0020] According to another second aspect of the embodiments of this disclosure, there is
provided a single doffing control method, including:
when a yarn is wound into a yarn bobbin of a predetermined size on a replaceable tube
on a winding mechanism in a spinning machine workstation, transmitting, by a control
apparatus, control information for instructing to replace the yarn bobbin on the winding
mechanism; and
replacing the yarn bobbin on the winding mechanism by using one of stored tubes when
a tube replacement apparatus receives the control information.
[0021] Hence, the yarn bobbin may be replaced with an empty tube automatically after the
yarn winding is completed by replacing the yarn bobbin on the winding mechanism with
the tube stored in the tube replacement apparatus, thereby eliminating or avoiding
artificial intervene, lowering maintenance cost, and improving security and operational
efficiency.
[0022] In some embodiments, the control apparatus transmits the control information to the
tube replacement apparatus in a case where a yarn length of the yarn bobbin reaches
a predetermined length, or a weight of the yarn bobbin reaches a predetermined weight,
or a diameter of the yarn bobbin reaches a predetermined diameter, or a length of
the yarn bobbin reaches a predetermined length.
[0023] Hence, a time for replacement may further be controlled exactly by the control apparatus,
and operational efficiency may be improved.
[0024] In some embodiments, the method further includes:
transmitting, by the control apparatus, a control instruction to stop winding to the
spinning machine workstation and causing the yarn bobbin to be ejected from the winding
mechanism to a conveyor belt in a case where a yarn length of the yarn bobbin reaches
a predetermined length, or a weight of the yarn bobbin reaches a predetermined weight,
or a diameter of the yarn bobbin reaches a predetermined diameter, or a length of
the yarn bobbin reaches a predetermined length.
[0025] Hence, the time for replacement may further be controlled exactly by the control
apparatus, and operational efficiency may be improved.
[0026] In some embodiments, the method further includes:
pushing out the one of the stored tubes by the tube replacement apparatus at an introduction
position and configuring the tube on the winding mechanism after the yarn bobbin on
the winding mechanism is ejected.
[0027] Hence, instructed by the control apparatus, the tube replacement apparatus and the
winding mechanism operate in parallel, the time for replacement may further be controlled
exactly by the control apparatus, and operational efficiency may be improved.
[0028] In some embodiments, the method further includes:
moving the tube replacement apparatus from a loading position to the introduction
position when the tube replacement apparatus receives a control instruction, or, moving
the tube replacement apparatus from a loading position to an introduction position
during spinning, or, moving the tube replacement apparatus from a loading position
to an introduction position after the tube replacement apparatus stores the tube(s),
and holding the tube replacement apparatus at the introduction position when the tube(s)
exist(s) in the tube replacement apparatus.
[0029] Hence, the tube replacement apparatus may reach the introduction position (standby
position) before the spinning process is suspended, thereby saving time for replacing
the tubes, further controlling exactly the time for replacing the tubes, and improving
operational efficiency.
[0030] In some embodiments, the method further includes:
detecting by the control apparatus whether the winding mechanism is configured with
the tube, and transmitting a control instruction for starting producing and winding
a yarn to the spinning machine workstation in a case where the tube is correctly configured
on the winding mechanism.
[0031] Hence, with the detection by the control apparatus, the time for operation again
of the winding mechanism may be exactly determined, and security and operational efficiency
may further be improved.
[0032] In some embodiments, the method further includes:
in the case where the tube is correctly configured on the winding mechanism, further
transmitting a control instruction by the control apparatus to the tube replacement
apparatus to cause the tube replacement apparatus to be moved from the introduction
position back to a standby position or a loading position.
[0033] Hence, with the detection by the control apparatus, the time for standby and introduction
of the tube replacement apparatus may be exactly determined, and security and operational
efficiency may further be improved. Moreover, after the tube replacement apparatus
is moved back to the loading position or the standby position, maintenance and loading
of the tubes may be better conducted.
[0034] According to a further aspect of the embodiments of this disclosure, there is provided
a single doffing control apparatus, including a memory and a processor, the memory
storing a computer program, and the processor being configured to execute the computer
program to implement the following operations:
when a yarn is wound into a yarn bobbin of a predetermined size on a replaceable tube
on a winding mechanism in a spinning machine workstation, transmitting control information
for instructing to replace the yarn bobbin on the winding mechanism, to enable a tube
replacement apparatus to replace the yarn bobbin on the winding mechanism by using
one of stored tubes.
[0035] An advantage of the embodiments of this disclosure exists in that the yarn bobbin
may be replaced with an empty tube automatically after the yarn winding is completed,
thereby eliminating or avoiding artificial intervene, lowering maintenance cost, and
improving security and operational efficiency.

[0043] Implementations of the embodiments of this disclosure shall be described below with
reference to the accompanying drawings.
[0044] An embodiment of this disclosure provides a single doffing device, including a spinning
machine workstation, a control apparatus and a tube replacement apparatus.
[0045] FIG. 1 is a schematic diagram of the spinning machine workstation of the embodiment
of this disclosure. As shown in FIG. 1, the spinning machine workstation 100 includes
a spinning mechanism 101 and a winding mechanism 102. The spinning machine workstation
100 is used for producing a yarn 11, and the winding mechanism 102 is used for winding
the yarn 11. As shown in FIG. 1, a yarn take-off device 103 may be provided between
the spinning mechanism 101 and the winding mechanism 102.
[0046] As shown in FIG. 1, the winding mechanism 102 may be configured with a tube 1021.
The yarn 11 may be cross-wound on the tube 1021to form a bobbin 1022. The winding
mechanism 102 may be separately driven by a driver, and may include a conveyor belt
for conveying the bobbin 1022, and reference may be made to related techniques for
detailed contents of the winding mechanism 102.
[0047] As shown in FIG. 1, the spinning machine workstation 100 may be controlled by a computer
workstation 12, and the computer workstation 12 may control actions of components
of one or more spinning machine workstations 100. The control apparatus in the embodiment
of this disclosure may be implemented by, for example, the computer workstation 12
shown in FIG. 1; however, this disclosure is not limited thereto, for example, the
control apparatus may also be one or some control circuits configured in the spinning
machine workstation 100 or other devices.
[0048] It should be noted that the spinning machine workstation of this disclosure is only
schematically described in FIG. 1; however, this disclosure is not limited thereto.
For example, other components or devices may also be provided, and reference may be
made to related techniques for details, which shall not be described herein any further.
And reference may be made to related techniques for those parts or elements (such
as a control line, and a connection element) that are not specified in FIG. 1, which
are not limited in this disclosure.
[0049] FIG. 2 is the schematic diagram of the single doffing device of the embodiment of
this disclosure, in which the control apparatus is omitted. FIG. 3 is a partial schematic
diagram of the single doffing device of FIG. 2, showing a case of a winding mechanism
of one spinning machine workstation and one tube replacement apparatus. And FIG. 4
is another schematic diagram of the single doffing device of FIG. 2, showing a case
viewed from a side.
[0050] As shown in FIGs. 2-4, the single doffing device 200 may include a spinning machine
workstation 201 and a tube replacement apparatus 202, and reference may be made to
FIG. 1 for a structure of the spinning machine workstation 201. In FIGs. 2-4, for
the sake of simplicity, reference number 201 is shown by taking one spinning machine
workstation as an example.
[0051] The spinning machine workstation 201 has a spinning mechanism (not shown in FIG.
2) for producing a yarn and a winding mechanism 2011 for winding the yarn, wherein
the winding mechanism 2011 is provided with a replaceable tube (as shown by 1021 in
FIG. 1, not shown in FIG. 2) around which the yarn is wound.
[0052] When a yarn is wound into a yarn bobbin (as shown by 1022 in FIG. 1, not shown in
FIG. 2) of a predetermined size around the replaceable tube on the winding mechanism
2011, the control apparatus (not shown in FIG. 2) transmits control information for
instructing to replace the yarn bobbin on the winding mechanism 2011.
[0053] The tube replacement apparatus 202 stores one or more tube(s) therein, and replaces
the yarn bobbin on the winding mechanism 2011 by using one of the stored tubes upon
receipt of the control information.
[0054] In some embodiments, as shown in FIG. 2, for example, multiple spinning machine workstations
201 (for example, 12 spinning machine workstations configured at the front side are
shown in FIG. 2), and one tube replacement apparatus 202 may be configured for each
spinning machine workstation 201 (one tube replacement apparatus configured at the
front side is only exemplarily shown in FIG. 2). One or more tube(s) may be stored
in the tube replacement apparatus 202 (for example, 6 tubes may be stored in parallel).
What described above are some examples of this disclosure only; however, this disclosure
in not limited thereto.
[0055] Hence, the yarn bobbin may be replaced with an empty tube automatically after the
yarn winding is completed by replacing the yarn bobbin on the winding mechanism with
the tube stored in the tube replacement apparatus, thereby eliminating or avoiding
artificial intervene, lowering maintenance cost, and improving security and operational
efficiency.
[0056] It should be noted that the single doffing device of this disclosure is only schematically
described in FIGs. 2-4; however, this disclosure is not limited thereto. For example,
other components or devices may also be provided, and reference may be made to related
techniques for details, which shall not be described herein any further. And reference
may be made to related techniques for those parts or elements (such as a control line)
that are not specified in FIGs. 2-4, which are not limited in this disclosure.
[0057] In some embodiments, the control apparatus transmits the control information to the
tube replacement apparatus 202 in a case where a yarn length of the yarn bobbin (a
total length of a yarn wound around the tube) reaches a predetermined length (a first
length), or a weight of the yarn bobbin reaches a predetermined weight, or a diameter
of the yarn bobbin reaches a predetermined diameter, or a length of the yarn bobbin
(a length of the yarn bobbin itself) reaches a predetermined length (a second length).
[0058] For example, assuming that the diameter of the yarn bobbin 1022 shown in FIG. 1 reaches
a pre-required diameter threshold, the yarn bobbin 1022 needs to be replaced. For
example, the yarn length may be detected by a sensor of the spinning mechanism, and
the diameter/length/weight of the yarn bobbin may be detected by the sensor of the
winding mechanism, etc., and reference may be made to related techniques for specific
detection components. This disclosure is not limited thereto, and the parameters as
doffing conditions may also be, for example, a volume of the yarn bobbin, etc. In
addition, the above doffing conditions may be used separately, or may be used by combining
two or more of them.
[0059] Hence, a time for replacement may further be controlled exactly by the control apparatus,
and operational efficiency may be improved.
[0060] In some embodiments, the control apparatus transmits a control instruction to stop
winding to the spinning machine workstation 201 and causes the yarn bobbin to be ejected
from the winding mechanism 2011 to a conveyor belt in a case where a yarn length of
the yarn bobbin reaches a predetermined length, or a weight of the yarn bobbin reaches
a predetermined weight, or a diameter of the yarn bobbin reaches a predetermined diameter,
or a length of the yarn bobbin reaches a predetermined length.
[0061] For example, after the spinning machine workstation 201 receives the control instruction,
it may deem that the winding of the yarn bobbin is completed, and hence production
and winding of the spinning machine workstation 201 may be stopped, and replacement
of the yarn bobbin may be prepared. For other spinning machine workstations 201, yarn
production and winding may still be performed independently and are not affected by
the control instruction.
[0062] Hence, the time for replacement may further be controlled exactly by the control
apparatus, and operational efficiency may be improved.
[0063] In some embodiments, the tube replacement apparatus 202 pushes out one of the stored
tubes at an introduction position and configures the tube on the winding mechanism
after the yarn bobbin on the winding mechanism is ejected.
[0064] Hence, instructed by the control apparatus, the tube replacement apparatus and the
winding mechanism operate in parallel (for example, the yarn bobbin is ejected, while
the stored empty tube is introduced), the time for replacement may further be controlled
exactly by the control apparatus, and operational efficiency may be improved.
[0065] In some embodiments, the introduction position refers to, for example, a position
where an empty tube in the tube replacement apparatus may be inserted into a bobbin
rack of the winding mechanism from a tube magazine, and the standby position refers
to, for example, a position where the tube replacement apparatus waits for a tube
replacement operation. The introduction position and the standby position may be in
the vicinity of the winding mechanism and have predetermined distances from the winding
mechanism.
[0066] The introduction position may be identical to the standby position, for example,
the tube replacement apparatus may be standby at a first predetermined position near
the winding mechanism and perform tube replacement at the first predetermined position;
and the introduction position and the standby position may also be different, for
example, the tube replacement may be standby at a second predetermined position near
the winding mechanism, and may perform tube replacement at a third predetermined position.
[0067] In some embodiments, the loading position refers to, for example, a position where
a tube is loaded (or stored) into the tube magazine of the tube replacement apparatus,
which may be remote from the induction or standby position. For example, the tube
magazine may be made more upright in the loading position, so that a tube to be loaded
(stored) may automatically slide into the tube magazine due to the gravity, thereby
simplifying operations of storing tubes by the tube magazine.
[0068] In addition, one or more of the introduction position, the standby position and the
loading position may be set as actually demanded. For example, only the introduction
position and the loading position may be set, or only the introduction position and
the standby position may be set, or the introduction position, the standby position
and the loading position may be set, and more positions may be set, etc., and this
disclosure is not limited thereto.
[0069] In some embodiments, the tube replacement apparatus is moved from the loading position
to the introduction position upon receiving a control instruction, or, the tube replacement
apparatus is moved from the loading position to the introduction position during spinning,
or, the tube replacement apparatus is moved from the loading position to the introduction
position after storing the tubes, and remains at the introduction position when the
tube(s) exist(s) in the tube replacement apparatus.
[0070] Hence, the tube replacement apparatus may reach the introduction position (standby
position) before the spinning process is suspended, thereby saving time for replacing
the tubes, further controlling exactly the time for replacing the tubes, and improving
operational efficiency.
[0071] For example, at any suitable moment during the spinning process, the tube replacement
apparatus may be moved to the introduction position, waiting for the spinning process
to be suspended, so as to insert the tube into the bobbin rack of the winding mechanism
immediately after the yarn bobbin is ejected. This may further save time as the tube
magazine does not need to be moved from the loading position to the introduction position
after the spinning process is suspended.
[0072] For another example, as shown in FIG. 3, it is assumed that the tube replacement
apparatus 202 is currently at the loading position. In a case where the control information
is received, the tube replacement apparatus 202 is moved from the loading position
(such as being rotated or translated, and rotation is taken as an example in FIG.
3) to an introduction position with a predetermined distance from the winding mechanism
2011 (such as being rotated downwards as shown by the arrow in FIG. 3). In this introduction
position, the tube replacement apparatus 202 is abutted with a guide rail of the winding
mechanism 2011 capable of guiding an empty tube.
[0073] For a further example, after the yarn bobbin on the winding mechanism 2011 is ejected
(such as being transferred to the conveyor belt), the tube replacement apparatus 202
pushes out the stored tube (such as pushing out a foremost tube by a pressure mechanism,
and reference may be made to relevant techniques for details), and configures (such
as introducing via the guide rail) the tube onto the winding mechanism 2011. Reference
may be made to relevant techniques for implementing such actions as ejecting, transferring,
pushing out, configuring, and introducing, which shall not be repeated herein any
further.
[0074] In some embodiments, the control apparatus detects whether the winding mechanism
2011 is configured with the tube, and transmits a control instruction for starting
producing and winding a yarn to the spinning machine workstation 201 in a case where
the tube is correctly configured on the winding mechanism 2011.
[0075] For example, whether the tube is configured, or whether the tube is configured at
a correct position, etc., may be detected by a detector. In the case where the tube
is correctly configured on the winding mechanism 2011, subsequent yarn production
and winding are proceeded; in a case where the tube is not correctly configured on
the winding mechanism 2011, introduction of the tube may be awaited; and in a case
where the tube are not properly configured after a predetermined time, an alert may
be issued to notify relevant personnel.
[0076] Hence, with the detection by the control apparatus, the time for operation again
of the winding mechanism may be exactly determined, and security and operational efficiency
may further be improved.
[0077] In some embodiments, in the case where the tubes are correctly configured on the
winding mechanism 2011, the control apparatus further transmits a control instruction
to the tube replacement apparatus 202 to cause the tube replacement apparatus 202
to be moved from the introduction position back to the loading position or a standby
position.
[0078] Hence, with the detection by the control apparatus, the time for standby and introduction
of the tube replacement apparatus may be exactly determined, and security and operational
efficiency may further be improved. Moreover, after the tube replacement apparatus
is moved back to the loading position or the standby position, maintenance and loading
of the tubes may be better conducted.
[0079] The above implementations only illustrate the embodiment of this disclosure. However,
this disclosure is not limited thereto, and appropriate variants may be made on the
basis of these implementations. For example, the above implementations may be executed
separately, or one or more of them may be executed in a combined manner.
[0080] In addition, the devices or components are illustrated above only. However, this
disclosure is not limited thereto, and reference may be made to related techniques
for detailed contents of the devices or components; and furthermore, devices or components
not shown in FIGs. 1-4 may be added, or one or more of the devices or components in
FIGs. 1-4 may be reduced.
[0081] It should be noted that the embodiments of this disclosure are only illustratively
described above. However, the embodiments of this disclosure are not limited thereto,
and appropriate variants may be made on the basis of the above implementations. In
addition, the components are illustrated above only. However, the embodiments of this
disclosure are not limited thereto, and reference may be made to related techniques
for detailed contents of the components. Moreover, components not shown in the drawings
may be added, or one or more components in the drawings may be reduced.
[0082] The embodiment of this disclosure further provides a single doffing control method.
[0083] FIG. 5 is a schematic diagram of the single doffing control method of the embodiment
of this disclosure. As shown in FIG. 5, the method includes:
501: when a yarn is wound into a yarn bobbin of a predetermined size around a replaceable
tube on a winding mechanism in a spinning machine workstation, a control apparatus
transmits control information for instructing to replace the yarn bobbin on the winding
mechanism; and
502: a tube replacement apparatus replaces the yarn bobbin on the winding mechanism
by using one of stored tubes when receiving the control information.
[0084] Hence, the yarn bobbin may be replaced with an empty tube automatically after the
yarn winding is completed by replacing the yarn bobbin on the winding mechanism with
the tube stored in the tube replacement apparatus, thereby eliminating or avoiding
artificial intervene, lowering maintenance cost, and improving security and operational
efficiency.
[0085] FIG. 6 is another schematic diagram of the single doffing control method of the embodiment
of this disclosure.
[0086] 601: a spinning machine workstation produces a yarn, and winds the yarn by using
tubes; and
[0087] 602: a control apparatus determines that the yarn is wound into a yarn bobbin of
a predetermined size around a tube;
for example, a yarn length of the yarn bobbin reaches a predetermined length, or a
weight of the yarn bobbin reaches a predetermined weight, or a diameter of the yarn
bobbin reaches a predetermined diameter, or a length of the yarn bobbin reaches a
predetermined length; and the above doffing conditions may be used separately, or
may be used by combining two or more of them;
[0088] 603: the control apparatus transmits control information for replacing the yarn bobbing
to the tube replacement apparatus;
in some embodiments, in a case where the control information is received, the tube
replacement apparatus is moved from the loading position to an introduction position
with a predetermined distance from the winding mechanism; for example, after the tube
replacement apparatus reaches the introduction position, a further instruction may
be awaited, and preparation for replacement may be started; however, this disclosure
is not limited thereto, for example, the tube replacement apparatus may reach the
introduction position at any appropriate time;
[0089] 604: the control apparatus transmits a control instruction to stop winding to the
spinning machine workstation, and causes the yarn bobbin to be ejected from the winding
mechanism to a conveyor belt;
for example, after receiving the control instruction, the spinning machine workstation
may cut off the yarn, and transfers the yarn bobbing to the conveyor belt for performing
subsequent processes; and furthermore, the control apparatus may further transmit
an instruction to the tube replacement apparatus, so as to cause the tube replacement
apparatus to start replacement of the tubes;
[0090] 605: the tube replacement apparatus pushes out one of the stored tubes after the
yarn bobbing on the winding mechanism is ejected, and configures the tube on the winding
mechanism.
