Description
[0001] The present invention relates to a method for supplying
cross-winding devices of a spinning-mill machine with sleeves,
whereas a multiple number of cross-winding devices is arranged next
to each other and on two machine sides located in the longitudinal
direction of the spinning-mill machine, and yarn is wound on
sleeves at the cross-winding devices, whereas empty sleeves are
stockpiled in at least one sleeve stack, and with a sleeve
transport device arranged along the cross-winding devices, with
which the cross-winding devices are supplied with empty sleeves
from the sleeve stack, whereas the sleeve transport device features
a continuous entraining element, in particular a conveyor belt,
which is moved along the multiple number of cross-winding devices
and a corresponding spinning-mill machine.
[0002] Modern textile machines, such as (for example) open-end
rotor spinning-mill machines or winding machines, are able to wind
different yarns on bobbins at their many work stations. For the
individual varying yarns, it is frequently necessary or at least
helpful for the later recognition of the respective yarn if
different sleeve types are provided on the textile machine. In this
case, one yarn type is wound on a specific sleeve, which is marked
in a particular color.
[0003] DE 43 44 058 A1 discloses a textile machine producing
cross-wound bobbins, such as a winding machine or an open-end
spinning-mill machine, with which a transport system internal to
the machine is arranged, which essentially consists of a
circulating continuous means of transport with spaced guide and
entraining elements, and which is guided in a guide rail structure.
Each of the guide and entraining elements features a receptacle for
an empty sleeve. Cross-wound bobbin carrier elements can be fed in
or out via connecting tracks in the transport system. The empty
cross-wound bobbin carrier elements that have been fed are
retracted by means of the guide and entraining elements arranged on
the continuous means of transport in defined change positions in
front of the winding stations. The geometrical allocation of the
empty sleeve receptacles or the cross-wound bobbin receptacles make
it possible for an automatically operating change unit to exchange
a finished cross-wound bobbin for an empty sleeve. The loaded
cross-wound bobbin carrier elements are then discharged from the
transport system via the connecting track.
[0004] However, the disadvantage here is that sleeves from a stack
internal to the machine cannot be transported over the entire
length. In addition, the provision of different sleeve types is
difficult, since the empty sleeve receptacles are firmly coupled
together, and this can conflict with the removal of the finished
cross-wound bobbins and the supply of the correct empty sleeve.
[0005] Thus, the task of the present invention is to provide a
spinning-mill machine, which is able to store different sleeve
types in a stack and to transport them as needed to a corresponding
work station with the shortest possible transport time.
[0006] The task is achieved with a spinning-mill machine with the
characteristics of the independent claim.
[0007] With the method in accordance with the invention for
supplying cross-winding devices of a spinning-mill machine with
sleeves, a multiple number of the cross-winding devices is arranged
next to each other and on two machine sides located in the
longitudinal direction of the spinning-mill machine. Yarn is wound
on sleeves at the cross-winding devices, whereas empty sleeves are
stockpiled in at least one sleeve stack. With a sleeve transport
device arranged along the cross-winding devices, the cross-winding
devices are supplied with empty sleeves from the sleeve stack,
whereas the sleeve transport device features a continuous
entraining element, in particular a conveyor belt, which is moved
along the multiple number of cross-winding devices.
[0008] In accordance with the invention, a multiple number of
transport carriages are provided for receiving a respective sleeve,
whereas the transport carriages are transported by means of the
continuous entraining element, in order to bring the sleeves to the
cross-winding devices. Various types of sleeves are stockpiled, and
each cross-winding device is allocated with with a predetermined
type of sleeve. The type of sleeve is detected and, together with
the transport carriages, the sleeve is supplied to the
cross-winding device allocated to it where required.
[0009] The different types of sleeves can be stored on an
intermediate basis in the carriages and, where required, conveyed
very rapidly to the corresponding cross-winding station. For this
purpose, the loaded carriages may be distributed along the machine,
in order to have a short path to the cross-winding station. It is
also possible that only with a request of a specific sleeve type
will it be placed on the carriages from the stack by means of a
corresponding handling device, and transported to the cross-winding
station by means of the continuous entraining element. In order to
obtain an allocation of the carriages to the sleeve and to be able
to deliver the correct sleeve, the type of sleeve is detected. This
can take place through the detection of the color or shape of the
sleeve or through a predetermined allocation of the sleeve type to
a specific sleeve stack. After the sleeve has been delivered to the
cross-winding station, the carriage is available for reloading with
a sleeve. For this purpose, the carriage is transported back to a
stack and once again loaded there.
[0010] In order to enable the tracking of the transport carriages
or the specific sleeve, it is particularly advantageous if the type
of sleeve and the individual transport carriages are linked
together. This link can take place by means of control technology,
by the carriage receiving a unique identifier. This identifier may
be, for example, a bar code with a unique number. When a sleeve
type is picked up, it is registered that the carriage with the
specified identifier is loaded with a specific sleeve type. If such
sleeve type is requested, the carriage is conveyed with the
corresponding identifier to the requesting cross-winding station,
and the correct sleeve can be picked up there.
[0011] Preferably, the location of the transport carriage on the
sleeve transport device is detected by a corresponding control
device. A rapid delivery of the carriage or the corresponding
sleeve, as the case may be, to the requesting cross-winding station
is possible. Thereby, the shortest delivery route can be
determined, and the transport of the corresponding carriage can be
effected.
[0012] It is advantageous if a control device manages the location
and destination of the transport carriage and directs the transport
carriage to the predetermined cross-winding device. Thus, a
need-based feeding of the transport carriage or the right sleeve,
as the case may be, to the cross-winding station, can take place.
The cross-winding station or its machine control device, as the
case may be, determines the need for a specific sleeve and issues a
request to the control device of the sleeve transport device. Thus,
the control device of the sleeve transport device determines where
suitable transport carriages are located, and where the requesting
cross-winding station is located. Then, a transport carriage is
selected by the control device, which transport carriage is able to
convey a sleeve as rapidly as possible to the cross-winding
station.
[0013] Depending on the design of the present invention, the
transport carriage is always led to a single machine side or,
optionally, one of the two machine sides. If only one of the two
machine sides is supplied, the system will have a higher capacity,
which can provide sleeves more rapidly and be simple in structure.
With a supply to both machine sides, the structure is somewhat more
complex in terms of construction and control technology. However,
different sleeves do not have to be stacked side by side, and a
greater variety of sleeve types can be provided.
[0014] A spinning-mill machine in accordance with the invention
features a multiple number of cross-winding devices arranged next
to each other and on two machine sides located in the longitudinal
direction of the spinning-mill machine, each of which is provided
for winding yarn on sleeves. At least one sleeve stack for
stockpiling empty sleeves and one sleeve transport device arranged
along the cross-winding devices for supplying the cross-winding
devices with empty sleeves from the sleeve stack are present. The
sleeve transport device features a continuous entraining element,
in particular a conveyor belt. Different types of sleeves can be
stockpiled in the sleeve stack. Each cross-winding device is
allocated with a predetermined type of sleeves.
[0015] In accordance with the invention, the sleeve transport
device features a multiple number of transport carriages for
receiving and transporting a respective sleeve.
[0016] A detection device, which detects the type of sleeve, is
provided. This detection device may be a sensor, which examines the
sleeve, for example, in terms of its color or shape. However, it
can also be a complete sleeve stack, in which only one sleeve type
is stored in a sorted manner. On the sleeve stack, a transfer
station is provided for transferring a sleeve to the transport
carriage. A writing device is provided for identifying the
transport carriage with respect to the type of entrained sleeve.
This writing device can be provided in a control device, in which a
connection between a specified transport carriage and a specified
sleeve type is created. The entraining element is guided around one
or both machine sides, in order to supply the sleeve together with
the transport carriages of the cross-winding device allocated to
it. Thereby, the transport carriage is conveyed, together with the
sleeve, with the continuous entraining element from the sleeve
stack to the requesting cross-winding station or even initially to
an intermediate storage device and then to a requesting
cross-winding station. If the continuous entraining element is a
transport belt, the carriage is connected to the belt in a
frictional-locking manner, and conveyed through the movement of the
belt to the predetermined destination. The carriage can be stopped
there, for example with a holding device, with respect to the belt
that continues to run, or the belt itself is stopped. The sleeve is
removed from the carriage with a handling device at the destination
of the cross-winding station, an intermediate storage device or a
maintenance device, for example a bobbin changer, and handled
further.
[0017] If, in an advantageous formation of the invention, multiple
sleeve stacks are arranged on each machine side, in particular next
to each other, the capacity of the sleeves provided is thereby
markedly increased compared to a front-side arrangement of the
sleeve stacks. Thus, significantly more sleeves can be stacked.
Thus, the mostly manually performed equipping of the sleeve stacks
with sleeves can be carried out with a high degree of efficiency,
since, given the high capacity, a re-equipping process must take
place only rarely.
[0018] Preferably, each sleeve stack is allocated exclusively to a
predetermined machine side for stockpiling empty sleeves for such
machine side. Thus, the design of the sleeve transport device is
particularly simple, since the sleeve does not need to be taken to
the other machine side. Since, in many cases, the different sleeve
types will be subdivided according to the machine sides, the
equipping of the sleeve stacks can often be carried out on a sorted
basis in a simple manner. In addition, the sleeve stacks can also
stockpile the sleeves in a chaotic manner, and transport the
respective sleeve type to the work station with an appropriate
selection system.
[0019] Advantageously, each separate machine side or both machine
sides together are allocated with a stationary sleeve transport
device. With the design with a stationary sleeve transport device
on each separate machine side, a simple construction of the
invention is possible. However, sleeves on one side cannot be used
for cross-winding stations on the other machine side. If a
stationary sleeve transport device is allocated to both machine
sides, sleeves that are stockpiled in the stack on one machine side
can be conveyed to a cross-winding station of the other machine
side. The construction cost is greater; however, a higher degree of
flexibility with respect to the supply of different sleeves to the
cross-winding stations of the entire machine is achieved.
[0020] If, in an advantageous design of the invention, a common
entraining element is arranged between the two machine sides, the
structural outlay can be reduced. Thereby, the return transport of
the transport carriage to the sleeve stack takes place by means of
the common entraining element between the two machine sides.
[0021] If the transport carriage features an identification
element, in particular a bar code or an RFID chip, in order to mark
the type of the sleeve on the transport carriage, a connection is
created between the carriage and the sleeve, which can easily be
followed by the control device and can deliver a specific
cross-winding station.
[0022] If the sleeve transport device is advantageously allocated
with a detection device, in particular a scanner, the location of
the transport carriage can be easily detected. Thus, a supply to
the requesting cross-winding station can easily take place, even if
the carriage is not in the starting position on the sleeve stack,
but is already on the way in the sleeve transport device.
[0023] If the sleeve transport device is allocated with a control
device in order to be able to manage the location and the
destination of the transport carriage, and to be able to guide the
transport carriage to the predetermined cross-winding device, the
system is highly flexible and can be operated as required. In doing
so, the control device can record and manage the need for sleeves,
the location of the carriage, the location of the required sleeve
and the destination of the transport order.
[0024] Preferably, multiple sleeve stacks are arranged in the area
of supply units of the spinning-mill machine, in particular on the
drive frame, the intermediate frame or the end frame of the
respective machine side. Thus, the sleeve stacks can be distributed
along the machine and, as a whole, bring about a shortening of the
feeding length of the spinning-mill machine.
[0025] The device and the method in accordance with the invention
are formed in accordance with the preceding description, whereas
the specified characteristics can be present individually or in any
combination.
[0026] Further advantages of the invention are described in the
following embodiments. The following is shown:
[0027] FIG. 1 a spinning-mill machine with a multiple number of
sleeve stacks at one machine end and one circumferential sleeve
transport device per machine,
[0028] FIG. 2 a spinning-mill machine with a multiple number of
sleeve stacks at both machine ends and one circumferential sleeve
transport device per machine,
[0029] FIG. 3 a spinning-mill machine with a multiple number of
sleeve stacks at one machine end and, in each case, one sleeve
transport device per machine side,
[0030] FIG. 4 a spinning-mill machine with a multiple number of
sleeve stacks at one machine end and, in each case, one sleeve
transport device per machine side, with a centrally arranged common
entraining element and
[0031] FIG. 5 a transport carriage with a sleeve.
[0032] With the following description of the illustrated
alternative embodiments, the same reference signs are used for
characteristics that are identical and/or at least comparable in
their arrangement and/or mode of action compared to the other
illustrated embodiments. To the extent that such are not described
once again in detail, their designs and/or modes of action
correspond to the designs and modes of action of the
characteristics described above.
[0033] FIG. 1 shows a top view of a spinning-mill machine 1 shown
in outline, for example an open-end rotor spinning-mill machine or
a winding machine. The spinning-mill machine 1 features a drive
frame 2 and an end frame 3, which are respectively arranged at the
end of the spinning-mill machine 1. The spinning-mill machine 1
features two machine sides in the longitudinal direction, on which
a multiple number of cross-winding devices 4 are arranged between
the drive frame 2 and the end frame 3. For reasons of clarity, only
one of the cross-winding devices 4 is provided with a reference
sign. The multiple number of cross-winding devices 4 is collected
into sections 5.1 to 5.5. In each section 5.1 to 5.5, eight
cross-winding devices 4 are arranged on each machine side. In each
of the cross-winding devices 4, a holder (not shown here) for a
sleeve 9 is provided, on which a yarn is wound cross-wise.
Depending on the yarn type, a different sleeve type is required.
This is necessary or at least helpful in order to, later on, be
able to more easily identify the yarn type that is located on the
sleeve 9, if the bobbin is no longer located on the cross-winding
unit 4.
[0034] In the present embodiment, a sleeve transport device 6 is
formed as a conveyor belt, on which transport carriages 8 are
located, placed on the sleeves 9 and transported to a predetermined
destination. The conveyor belt of the sleeve transport device 6
surrounds the machine 1, and thus can reach all of the
cross-winding devices 4 and sleeve stacks 7.1 to 7.4. The sleeves 9
are initially located in a large number in a multiple number of
sleeve stacks 7.1 to 7.4. In the embodiment of FIG. 1, two sleeve
stacks 7.1 and 7.2 or 7.3 and 7.4, as the case may be, are arranged
in the end frame 3 on each machine side. The two sleeve stacks 7.1
and 7.2 or 7.3 and 7.4, as the case may be, are arranged one behind
the other in the direction of the machine. As a result, they cling
closely to the spinning-mill machine 1, and thus require little
installation space. However, they can also be arranged elsewhere in
the end frame 3, for example on the front side or on the front side
and the longitudinal sides of the end frame 3. In the sleeve stacks
7.1 and 7.2 or 7.3 and 7.4, as the case may be, a sorted stacking
of the sleeves 9 takes place, such that, by such four existing
sleeve stacks 7.1 to 7.4 (for example), four different sleeve types
can be stacked. In terms of control technology, the transmission of
the sleeves 9 to the corresponding cross-winding devices 4 can take
place very easily, since the sleeve type in which the sleeve stacks
7.1 to 7.4 is located is known.
[0035] To send the sleeves 9, a specified sleeve type from the
sleeve stack 7.1 to 7.4, in which the corresponding sleeve 9 is
stacked, is placed on a carriage 8. The conveyor belt of the sleeve
transport device 6 begins to move, and thus conveys the carriage 8
to the desired cross-winding station 4. Alternatively, with a
constantly moving conveyor belt, a stopping device can bring the
carriage 8 to a halt at the corresponding sleeve stack 7.1 to 7.4
and the desired cross-winding station 4.
[0036] FIG. 2 shows a spinning-mill machine 1, which has a similar
construction to the spinning-mill machine 1 of FIG. 1. With the
design of FIG. 2, the arrangement of the sleeve stacks 7.1 to 7.4
varies. Two of the sleeve stacks 7.1, 7.3 are arranged on the end
frame 3 of the spinning-mill machine 1, while the other two sleeve
stacks 7.2, 7.4 are arranged on the drive frame 2. The sleeve
transport device 6 in turn extends around the entire machine 1 and
passes through a cross-winding station 4 and each of the sleeve
stacks 7.1 to 7.4 and thus both machine sides. The distribution of
the sleeve stacks 7.1 to 7.4 on the drive frame 2 and the end frame
3 can be advantageous in terms of space utilization on the machine
1. The carriages 8 (not shown), just like in FIG. 1, move to a
conveyor belt of the sleeve transport device 6.
[0037] It can be provided that the sleeve transport device 6 can
transport the sleeves 9 only in one direction. However, in another
design, it can also be provided that the sleeve transport device 6,
as indicated by the arrows in both directions, can transport
sleeves 9 in both directions. In this case, the control device of
the sleeve transport device 6 can determine how the supply of the
required sleeve 9 can be done most rapidly, and accordingly
determine the direction of transport. Thus, on the one hand, a
sleeve 9 can be transported from the sleeve stack 7.1 in the
direction of the sleeve stack 7.2 and, on the other hand, a sleeve
9 can be transported from the sleeve stack 7.2 in the direction of
the sleeve stack 7.1. The same applies to the opposite machine side
by analogy.
[0038] This arrangement can be more favorable in terms of space
requirements and allows additional sleeve stacks 7.1 to 7.4,
similar to those shown in FIG. 1, to be arranged on the
spinning-mill machine 1 following the respective sleeve stack.
Thus, the capacity of the stackable sleeves 9 was even more
expandable.
[0039] In FIG. 3, a sleeve transport device 6.1 or 6.2, as the case
may be, is arranged along the multiple number of cross-winding
devices 4 on each side of the spinning-mill machine 1. In the
present embodiment, each of the sleeve transport devices 6.1 and
6.2 is formed as a conveyor belt, on which transport carriages 8
are located, placed on the sleeves 9 and transported to a
predetermined destination. The sleeves 9 are initially located in a
large number in a multiple number of sleeve stacks 7.1 to 7.4. In
the embodiment of FIG. 3, two sleeve stacks 7.1 and 7.2 or 7.3 and
7.4, as the case may be, are arranged in the end frame 3 on each
machine side. The two sleeve stacks 7.1 and 7.2 or 7.3 and 7.4, as
the case may be, are arranged one behind the other in the direction
of the machine. Due to the division on each machine side into two
sleeve stacks 7.1 and 7.2 or 7.3 and 7.4, as the case may be, the
system is even more flexible. A sorted stacking of the sleeves 9 is
possible, such that, by such four existing sleeve stacks 7.1 to 7.4
(for example), four different sleeve types can be stacked.
[0040] In the present embodiment, the sleeve transport devices 6.1
and 6.2 have a single direction of transport in the direction of
the arrow. This means that the sleeves 9 are removed from the
sleeve stacks 7.1 to 7.4, transferred to the sleeve transport
device 6 or the carriages 8 and moved in the direction of the
arrow.
[0041] Each of the sleeve transport devices 6.1 and 6.2 extends
along all of the cross-winding devices 4 or sections 5.1 to 5.5, as
the case may be, of a machine side and returns, in the machine
center, back to the sleeve stack 7.1 and 7.2 or 7.3 and 7.4, as the
case may be. Thus, each sleeve 9, which is arranged in one of the
sleeve stacks 7.1 to 7.4, can be supplied to any work station or
cross-winding station 4, as the case may be, on its machine
side.
[0042] FIG. 4 shows a spinning-mill machine 1 with a multiple
number of sleeve stacks 7.1 to 7.4 at one machine end, in this case
the end frame 3, and in each case a sleeve transport device 6.1,
6.2 per machine side, with a centrally arranged common entraining
element. The entraining element is once again a conveyor belt, on
which the carriages 8 are arranged. The centrally arranged common
entraining element serves both sleeve transport devices 6.1 and 6.2
for the return transport of the empty carriages 8. However,
carriages 8 loaded with sleeves 9 can also be conveyed in this
middle track section. By means of a switch 12, the carriages 8 are
guided by or on the sleeve transport device 6.1, 6.2. Thereby, the
carriages 8 can be directed to the sleeve transport device 6.1 or
6.2 on which they are currently needed. This design has the
advantage that sleeves 9 can be conveyed out of each of the sleeve
stacks 7.1 to 7.4 to each machine side. Thus, each side can access
each stored sleeve type.
[0043] Depending on the yarn type on the corresponding
cross-winding device 4, a sleeve type is requested. The control of
the sleeve transport devices 6.1 and 6.2 is designed in such a
manner that the sleeve 9 is placed on the sleeve transport device 6
and the carriage 8 from the sleeve stack 7.1 to 7.4 in which the
requested sleeve type is located.
[0044] FIG. 5 shows a transport carriage 8 in a perspective view.
The carriage 8 has a flat bottom plate, with which it rests on the
conveyor belt of the sleeve transport devices 6 or 6.1 and 6.2, as
the case may be, and can be taken from the moving conveyor belt. On
the bottom plate, the sleeve 9 is held in guides 10. The guides 10
ensure the secure reception of the sleeve 9, so that they cannot
fall from the carriage 8 during transport. On the other hand, the
guides 10 also enable the sleeve 9 to be easily place, for example
with gripper, on the carriage 8, and once again removed. The bottom
plate has tapered end pieces, so that the carriage 8 can be
conveyed through the curves of the sleeve transport devices 6 and
6.1 and 6.2, easily and without entanglement. In addition, the
carriage 8 features a bar code 11, with which it is uniquely
identifiable. Thus, the carriage 8 can be linked with its data to a
sleeve 9 via a control device. Thus, a clear allocation of a
specific sleeve type to the carriage 8, and thus to the location of
the sleeve 9 or the carriage 9, as the case may be, is also
possible.
[0045] At each of the sleeve stacks 7.1 to 7.4, a detection device
is provided; this detects the type of the sleeve 9. If the sleeve 9
is transferred from the sleeve stack 7.1 to 7.4 to a transfer
station at the transport carriage 8, the sleeve type 9 is linked to
