Description

The present invention relates to a winder for winding a plurality of threads in parallel to a package according to the higher concept part of claim 1.

A winder of this type is known from International Publication No. 2006/092237 (WO 2006/092237 A1).

This known winder is used to wind a group of yarns produced in a melt spinning process. The threads of the thread group are wound parallel to each other and wound into the package. For this purpose, the take-up machine has a plurality of take-up points formed on the machine frame along a take-up spindle that is cantilevered and held. The take-up spindle is used to house the package for simultaneous winding on the package. Since the winding of the yarn is performed by so-called twill winding, each yarn is individually guided back and forth within the winding location by the twill swing unit before being wound on the package surface. The supply and separation of the yarn group at the winding point is carried out via a plurality of rotatably supported mutating rollers, which are supported by a movable support. At this time, each turning roller forms one twill swing plane together with the correspondingly arranged twill swing units, and the thread is reciprocally guided in the twill swing plane. In such a state, the support is fixed to the mechanical frame of the winder at the operating position.

In order to allow the yarn of the yarn group to be threaded at the winding point of the winder at the start of the process, the support having the reversing roller is pulled out from the machine frame so that the reversing roller can be threaded from the operation side. Is done. At this time, the support is manually moved by the operator.

However, when producing synthetic yarns, it is desirable that as many yarns as possible be wound simultaneously in the winder. Therefore, it requires a very long support that must be guided to the work path with a corresponding extrusion length. This makes the gimmick process difficult for workers who have to guide the support on the one hand and thread on the reversing rollers on the other.

Further, it is known that when the yarn is wound, strong large and small vibrations are generated in the machine frame depending on the number of rotations of the spindle each time. Therefore, the yarn is wound into the package at a constant winding speed and thus at a constant peripheral speed. In order to keep the peripheral speed of the package constant, the rotation speed of the take-up spindle is adjusted according to the diameter of the package. These vibrations generated in the mechanical frame occur especially at winding points corresponding to the protruding free ends of the take-up spindle. At this time, it is known that such vibration also affects the support of the conversion roller and acts on all the bearings of the conversion roller.

Therefore, an object of the present invention is to improve such a type of winder to hold the converting roller in the machine frame with as little vibration as possible.

A further object of the present invention is to improve the winding machine of this type in the threading operability at the start of the process.

According to the present invention, such a problem is solved by a winder having the characteristics according to claim 1.

Advantageous improvements of the invention are defined by the features and combinations of features of the dependent claims.

The present invention has the special advantage that the converting rollers are supported on the machine frame independently of each other. For this purpose, roller holders are arranged correspondingly to each conversion roller, and the conversion rollers are supported by the roller holders. In the roller holder, adjacent converting rollers are held together at a winding interval at the operating position and at a threading interval at the threading position. At this time, the winding interval is larger than the threading interval. As such, they are movably guided by the roller support without depending on each other. At the same time, operability at the protruding end of the take-up spindle by the operator can be realized. Therefore, all roller holders with convertible rollers can be guided towards the protruding end of the take-up spindle to facilitate threading at the start of the process. Subsequently, the roller holder with the reversing rollers can be guided within the take-up location at the operating position. The mutual influence of the converting rollers is minimized by the separately provided supports in the roller holder.

An improved form of the present invention is particularly preferred for automating the threading process at the take-up location, in which at least one of the roller holders is correspondingly arranged with a linear drive. When adjacent roller holders are connected to each other by variable length coupling means. Therefore, although the roller holders have individual mobility, they can be guided between the operating position and the threading position by a linear drive device.

The linear drive is preferably connected to a take-up control unit and can be operated via a control panel. In this way, the mechanism process in the winder can be carried out while being adjusted.

An improved form of the present invention is particularly advantageous in order to allow fine thread gimmicks and take-ups at all take-up points of the take-up machine, in which the convertible rollers are located at the take-up points. And it is coupled to the drive so that it can be driven outside the take-up location. By doing so, the converting roller can already be driven at a predetermined peripheral speed at the threading position. As a result, it is possible to avoid particularly unacceptable fluctuations in thread tension during threading.

In order to guarantee the drive of the turning roller at the winding point, the drive device can be configured with various structures. According to one particularly advantageous alternative embodiment, the drive has a belt drive, which is connected to the transforming roller by shape or frictional connections and is separate. It is held on the drive support of the drive, which is stationary or movably incorporated into the mechanical frame.

At this time, the belt drive device may have a driven toothed belt, and the driven toothed belt cooperates with each one of a plurality of toothed pulleys, and the toothed pulley is operated. Is non-rotatably connected to a turning roller.

Another particularly advantageous variant of the belt drive is a driven magnet belt, which is non-contact with multiple magnet disks non-rotatably connected to a converting roller. Work together. At this time, since the magnet belt advantageously extends over the entire length of the mechanical frame, continuous drive of the converting roller is guaranteed even during relative movement between the magnet disk and the magnet belt.

When the drive support of the belt drive is movably held by the mechanical frame, an improved embodiment of the present invention is preferably carried out, in which the take-up control unit is a feed acting on the drive support. It is coupled to the drive device, and the linear drive device and the feed drive device of the roller holder can be synchronously controlled. Thus, for example, the coupling by shape connection between the toothed disc and the toothed belt will continue to exist during the movement of the roller holder.

However, basically, the drive device may be composed of a plurality of electric motors each held by a roller holder and connected to a turning roller. At this time, power can be supplied to these electric motors via one energy chain.

However, optionally, the electric motor may be connected to a plurality of filling stations at the operating position of the converting roller and the threading position of the converting roller. At this time, the motor receives the required supplied energy and control signals transmitted only at the operating position and the threading position.

At this time, the supply energy and the control signal are preferably transmitted in a non-contact manner. For this purpose, a modification of the present invention is provided in which a plurality of transmission means for wireless energy transfer are provided between the electric motor and the filling station.

An improved form of the present invention is particularly advantageous in order to allow the converting roller to generate as uniform torque as possible during all stages of threading and operation, in which the electric motor Corresponding capacitors are arranged for energy storage. At this time, the capacitor functions as an energy storage device that guarantees the energy supply to the electric motor outside the filling station.

For further description of the present invention, some embodiments of the winder according to the present invention will be described in detail below with reference to the accompanying drawings.

It is a figure which shows the part of the back view of the embodiment of FIG. 7 schematically.

In FIGS. 1 and 2, the first embodiment of the winder according to the invention is shown in a plurality of directions. FIG. 1 shows a side view of the present embodiment, and FIG. 2 shows a front view. An embodiment of the winder according to the present invention is shown in an operating state in FIGS. 1 and 2, respectively, and in this operating state, a group of a plurality of threads are simultaneously wound into a package. In this respect, at the same time, the function of the winder can be clearly shown by the running of the yarn.

The following description of this embodiment of FIGS. 1 and 2 applies to both drawings unless one of these drawings is explicitly stated.

In this embodiment, the take-up machine has a total of five take-up points 1.1 to 1.5 formed along a cantilever-protruding take-up spindle 10.1. The number of winding points is an example. Therefore, it has long been customary to wind ten, twelve or more threads parallel to each other into a package on a driven take-up spindle.

In the present embodiment, the take-up spindle 10.1 is held by a take-up revolver 11 rotatably supported, and the take-up revolver 11 is displaced by 180 ° to a second take-up spindle 10. Supports 2. Two spindle drive devices 20.1 and 0.2 are arranged correspondingly to the take-up spindles 10.1 and 10.2, respectively. The rotational movement of the take-up revolver 11 rotatably supported in the machine frame 14 is performed by the revolver drive device 22. The revolver drive device 22 allows the take-up revolver 11 to move with the take-up spindles 10.1 and 10.2. Therefore, the take-up spindles 10.1 and 10.2 can alternately rotate to the replacement region and the operating region. Since a plurality of winding tubes 13 are arranged around the winding spindles 10.1 and 10.2, one package 12 is wound on the winding tube 13 at every 1.1 to 1.5 winding points. It is possible to take it.

In the operating state shown in FIGS. 1 and 2, a total of 5 threads 2 are simultaneously wound into the 5 packages 12 on the take-up spindle 10.1.

The take-up points 1.1 to 1.5 formed in the take-up machine each have a turning roller 3.1 to 3.5 in the run-in region for thread separation and guidance. The conversion rollers 3.1 to 3.5 of No. 3 cooperate with the twill swing unit 4 within the respective winding points 1.1 to 1.5. The turning rollers 3.1 to 3.5 and the correspondingly arranged twill swing unit 4 form a so-called twill swing plane, and the thread 2 is reciprocated in this plane, so that twill winding occurs around the package. .. For this reason, the twill swing unit 4 formed at the winding points 1.1 to 1.5 has a twill swing means, and the twill swing means guides the thread in the twill swing stroke. At this time, as the twill swinging means, a thread guide that reciprocates or a plurality of thread guides that perform translational motion may be used.

The winding of yarn around the package 12 is supported by a rotatable pressing roller 9, which extends over all winding points 1.1-1.5 and is packaged. It is in contact with the circumference of 12.

In the upper region of the machine frame 14, conversion rollers 3.1 to 3.5 are rotatably supported by a plurality of roller holders 5.1 to 5.5. The roller holders 5.1-5.5 include bearings 17 of the converting rollers 3.1-3.5, which are not shown in detail here. Each of the roller holders 5.1 to 5.5 is movably configured and is arranged on the roller support 6. The roller support 6 is formed by a guide rod in this case, and the guide rod extends above the winding point on the machine frame 14 in parallel with the winding spindle 10.1.

The roller holder 5.1 arranged corresponding to the support end portion of the take-up spindle 10.1 is connected to the linear drive device 15.

Between the adjacent roller holders 5.1 and 5.2, between 5.2 and 5.3, between 5.3 and 5.4, and between 5.4 and 5.5 The coupling means in the form of the nested rod 7 are arranged respectively. The nested rod 7 connects the roller holders 5.1 to 5.5 to each other, and at this time, the nested rod 7 is configured to have a variable length. With such a configuration, the roller holders 5.1 to 5.5 can be moved in the roller support 6 in the axial direction by the linear drive device 15. In the state shown in FIGS. 1 and 2, the roller holders 5.1 to 5.5 are held at operating positions where the yarn 2 is wound around the package 12, respectively. At this time, the thread 2 is guided in a state of being partially wound around the turning rollers 3.1 to 3.5.

The linear drive device 15 is connected to the take-up control unit 8 via a control line. The take-up control unit 8 is connected in parallel to the control panel 18 on the front operation side of the take-up machine and the drive electronic device 19. The drive electronic device 19 is connected to the spindle drive device 20.1.2.2, the twill swing drive device 21 of the twill swing unit 4, and the revolver drive device 22. The operation and drive control of the drive devices 20.1 / 0.2, 21 and 22 are performed via the generally shown take-up control unit 8 and the correspondingly arranged control panels 18.

In the present embodiment shown in FIGS. 1 and 2, driven godets 23 are arranged correspondingly at winding points 1.1 to 1.5, and the godets 23 are arranged on the side of the winder. Since it is held, the thread 2 is supplied to the turning rollers 3.1 to 3.5 at the winding points 1.1 to 1.5 without further spreading by the thread guides oriented substantially horizontally. Can be done. The godet 23 is driven via the godet drive device 24 controlled by the godet control device 25.

In the operating state of the winder shown in FIGS. 1 and 2, the yarn 2 is supplied as one yarn group to the winding points 1.1 to 1.5 via the godette 23, and the turning roller 3.1. Separated via ~ 3.5. Subsequently, each thread 2 is separately wound into one of a plurality of packages 12 provided around the winding spindle 10.1 within the winding points 1.1 to 1.5.

When the package reaches the desired final diameter, the spindle is replaced. At this time, the take-up spindle 10.1 is rotated to the replacement region, and the take-up spindle 10.2 is rotated to the operating region. At this time, the yarn is automatically captured and taken up by the winding tube 13 existing around the take-up spindle 10.2, so that the yarn is taken up around the take-up spindle 10.2 to form a new package.

The winders shown in FIGS. 1 and 2 are particularly suitable for holding a large number of winding points side by side. By separately supporting the conversion rollers 3.1 to 3.5 in the roller holders 5.1 to 5.5, the support portions of the conversion rollers 3.1 to 3.5 are separately provided. , Mutual vibrations do not affect each other. Further, the roller holders 5.1 to 5.5 can be transferred to one threading position inside the machine frame 14 among a plurality of illustrated operating positions. The threading positions of the roller holders 5.1 to 5.5 are shown by broken lines in FIG.

As is clear from FIG. 1, first, the roller holder 5.1 arranged on the roller support 6 is moved toward the protruding spindle free end of the take-up spindle 10.1 via the linear drive device 15. .. At this time, since the nesting rod 7 arranged between the roller holders 5.1 and 5.2 is also pressed, the next roller holder 5.2 is carried as the pressing motion progresses. Therefore, as the pressing motion of the linear drive device 15 progresses, all the roller holders 5.1 to 5.5 arranged on the roller support 6 are moved to the end stopper 16 at the free end of the take-up spindle 10.1. I can guide you. At the threading positions indicated by the broken lines of the roller holders 5.1 to 5.5, the converting rollers 3.1 to 3.5 each have a threading interval between them. At this time, the threading interval is much smaller than the winding interval generated at the operating position of the roller holders 5.1 to 5.5 between the adjacent converting rollers 3.1 to 3.5, respectively. In this case, the winding interval is a pitch of winding points 1.1 to 1.5. The threading interval of the converting rollers 3.1 to 3.5 at the threading position depends on the coupling means 7. Basically, other coupling means that can significantly shorten the spacing between the converting rollers 3.1-3.5 may be used.

At the threading position shown by the broken line in FIG. 1, the operator can easily hang the thread 2 on the turning rollers 3.1 to 3.5 at the start of the process. At this time, the operation of the linear drive device 15 is possible by a simple key input on the control panel 18. Therefore, the operator can execute all the work processes quickly and easily even if there are many winding points.

In the embodiment shown in FIGS. 1 and 2 of the winder according to the present invention, a drive device is arranged correspondingly to the conversion rollers 3.1 to 3.5, and the conversion roller is actively activated by this drive device. It can also be driven to. Therefore, in FIG. 2, as an example of the plurality of electric motors 26, how they are arranged on the back surface of the roller holders 5.1 to 5.5 is shown by a broken line. Drive control of these electric motors and energy supply to these electric motors can be performed via a flexible energy chain (energy supply line). Therefore, the converting rollers 3.1 to 3.5 can be continuously driven at both the operating position and the threading position. This is particularly advantageous when setting and winding a thread having a small count.

Moreover, the drive device 27 shown in FIG. 2 may be implemented by other drive means. Therefore, for example, FIGS. 3 and 4 show another embodiment of the winder according to the present invention, and FIGS. 3 and 4 are configured to be different from the embodiments of FIGS. 1 and 2. Only the device part is shown. For example, FIG. 3 shows a part of a front view of an embodiment of a winder, and FIG. 4 schematically shows a part of a rear view of an embodiment of a winder. Unless one of these drawings is explicitly stated, the following statements apply to both drawings.

In the embodiments shown in FIGS. 3 and 4, the converting rollers 3.1 to 3.5 and the roller holders 5.1 to 5.5 are configured in the same manner as in the above-described embodiment, and the roller supports 6 is movable in the axial direction by the linear drive device 15. A drive device 27 having a belt drive device 28 is formed on the back surface of the roller holders 5.1 to 5.5. In the present embodiment, the belt driving device 28 is formed by one toothed belt 29 and two belt pulleys 30.1, 30.2 arranged at intervals from each other. The belt pulley 30.2 is coupled to the motor 34 via the motor shaft 35. The belt pulleys 30.1, 30.2 are rotatably supported by the drive device support 31. The drive device support 31 is held by the machine frame 14 on the guide rail 36 so as to be movable in the axial direction. On one side of the drive device support 31, a feed drive device 32 capable of reciprocating the drive device support 31 between the operating position and the threading position in the mechanical frame 14 is provided.

In particular, as is clear from FIG. 3, one toothed pulley 33 is rotatably held on the back surface of each of the roller holders 5.1 to 5.5, and the toothed pulley 33 is a turning roller. It is relatively non-rotatably coupled to 3.1-3.5. Since the toothed pulley 33 is engaged with the toothed belt 29, transmission by shape connection is possible between the toothed belt 29 and the toothed pulley 33. Therefore, all the converting rollers 3.1 to 3.5 can be uniformly driven via the belt driving device 28.

At the start of the process, the transforming rollers 3.1-3.5 and the drive 27 are guided together to the threading position at the free end of the take-up spindle. By doing so, the converting rollers 3.1 to 3.5 can be continuously driven at the threading position. When the threading is completed, the linear drive device 15 and the feed drive device 32 are synchronously controlled, so that the roller holders 5.1 to 5.5 and the belt drive device 28 are guided to the operating positions. By doing so, the continuous drive of the transforming rollers continues to be maintained in all operating conditions of the winder.

The drive device 27 for driving the transforming rollers 3.1 to 3.5, shown in FIGS. 3 and 4, may be modified to transmit the rotational motion by frictional connection instead of transmission by shape connection. It is possible. With respect to this, FIG. 5 shows a part of a rear view of another embodiment of the winder according to the present invention. Since the embodiment of FIG. 5 is substantially the same as the embodiment of FIGS. 3 and 4, only the differences will be described here.

In the drive device 27 shown in FIG. 5, the belt drive device 28 is formed by a magnet belt 34. The magnet belt 34 includes a large number of magnets having alternating polarities. The magnet belt 34 is guided by a belt pulley 30.1 and a belt pulley 30.2 (not shown here). A plurality of magnet disks 35 are correspondingly arranged on the magnet belt 34 at short intervals, and these magnet disks 35 are rotatably held on the back surface of the roller holders 5.1 to 5.5. And is coupled to the converting rollers 3.1-3.5. In FIG. 5, only the magnet disk 35 of the roller holder 5.5 is shown. In such a case, torque transmission is performed by the magnetic force formed between the magnet disk 35 and the magnet belt 34.

In the embodiment shown in FIG. 5, the belt drive device 28 is held by the drive device support 31. Moreover, at this time, the drive device support 31 may be formed stationary in the machine frame and may extend over the entire length of the take-up spindle. The non-contact coupling between the magnet disk 35 and the magnet belt 34 allows the relative movement of the roller holders 5.1 to 5.5 without interruption of driving. Therefore, it is preferable that the magnet belt extends over the region of the threading position and the operating position of the turning rollers 3.1 to 3.5.

Another embodiment of the drive device 27 is shown in FIG. 6 in order to allow the turning rollers 3.1 to 3.5 to generate the highest possible torque. Since the embodiment of FIG. 6 is substantially the same as the embodiment of FIG. 5, the above description is referred to, but only the differences will be described here with respect to other points.

In the embodiment shown in FIG. 6 of the drive device 27 of the turning rollers 3.1 to 3.5, the magnet belt 34 acts on both sides of the magnet disk 35 in the radial direction, and thus the generated torque increases. As described above, the magnet disk 35 is arranged between the belt pulleys 30.1 and 30.2.

In the modified examples of the winder according to the present invention shown in FIGS. 1 and 2, a selective drive device having a plurality of electric motors was provided. In the case of such a drive device, basically, the electric motor that drives the turning rollers 3.1 to 3.5 can also operate without an energy chain (energy supply line). In this regard, FIGS. 7 and 8 show one feasible embodiment of the drive 27, for example, how the drive 27 can be used in the winders shown in FIGS. 1 and 2. It is shown. A plurality of filling stations 37 arranged on the back surface of the roller holders 5.1 to 5.5 are correspondingly arranged in the electric motor 26 arranged in the roller holders 5.1 to 5.5. In each electric motor 26, one separate filling station 37 is correspondingly arranged at the operating position of the turning rollers 3.1 to 3.5. These filling stations 37 are identically configured and have a transmitter 38 for transmitting supply energy and control signals to the electric motor 26. In this case, energy transfer can be performed by inductive connection by an induction coil or optical connection. Moreover, the transmitter 38 may optionally have an automatic connector that forms a connection between the filling station 37 and the motor 26 at the operating position.

As is particularly clear from FIG. 8, a filling station group 40 is provided outside the winding portion of the protruding end of the machine frame 14, and the filling station group 40 changes the energy supply to the electric motor 26. Guaranteeed at the threading position of the facing rollers 3.1 to 3.5. By doing so, the converting rollers 3.1 to 3.5 can be continuously driven by the correspondingly arranged electric motors 26 at the operating position and the threading position.

In the embodiment shown in FIG. 7, the electric motor 26 is correspondingly arranged with a capacitor 39 that is directly connected to the electric motor 26 and forms an energy buffer. As a result, the energy supply to the electric motor 26 can be maintained for a short time without the action of the filling station 37. Therefore, such energy supply enables continuous driving of the turning rollers 3.1 to 3.5 at the time of transition from the threading position to the operating position. In such a state, one thread is guided around each of the converting rollers 3.1 to 3.5.

The winder according to the present invention is suitable for winding a large number of yarns at a large number of winding points regardless of the presence or absence of a driven converting roller. In addition, the individual mobility of the converting rollers makes it possible to achieve easy operability, especially at the start of the process.
