Description

The invention relates to a device for equipping the bobbin mandrels of a creel with full bobbins, with a fitting device that attaches the full bobbins of a bobbin to the stacked horizontal mandrels of a transfer carriage, which is rail-bound by a travel drive from a loading position located next to the gate the assembly of the bobbins of this gate serving bobbin transfer positions is movable, the full yarn bobbins form a single vertical mandrel row and in a bobbin transfer position are aligned with bobbins of the gate, and which is provided with a bobbin transfer device.

Such a device is known from DE-A-35 38 838. In the known device, the process for transferring the full spools of thread is such that they are transferred to the transfer carriage in the loading position. Then the transfer carriage fully loaded with the payout spools is brought to a spool transfer position and the payoff spools are simultaneously transferred to the creel. The coils must be transferred to the transfer carriage in such an order that the desired pattern of the coils on the mandrels is achieved by pushing the coils over. Errors in the sequence of the full bobbins to be transferred can no longer be corrected in the area of the transfer carriage.

In contrast, the invention has for its object to improve a device with the features mentioned so that the creel can be equipped with simple means according to the pattern, while at the same time removing the bobbin tubes after unwinding the bobbins in the sense of minimizing the time required .

This object is achieved in that, together with it, a sleeve removal device can be moved remotely on a bottom rail, which has a rest position on the take-off side, from which it can be controlled to remove the bobbin cases to the row of thorns which are the most distant from the take-off, from which the row of bobbins can be removed from the bobbins is able to remove one after the other, and that the transfer carriage is controllable to the sleeve-free gate rows during operation of the sleeve removal device.

Advantageous further developments of the invention are characterized in the subclaims.

The transfer carriage is moved between a coil transfer position in the vicinity of the coil gate and a coil take-over point in the vicinity of the pick and place device, wherein coil transfer and take-over can take place independently of the operation of the coil gate. A vertical row of mandrels is used for the orderly reception and transfer of the yarn bobbins, which is loaded by the loading device as required by the loading of the bobbin creel. Expediently, there is only a single vertical row of mandrels in order to keep the construction costs of the loading device and the transfer carriage low. However, it is understood that parallel mandrel rows can also be used if necessary. The mandrels are aligned with the spindles in the spool transfer position of the transfer car, so they have a division that corresponds to the division of the spool spindles of the gate. In addition, the transfer carriages are designed so that a spool transfer device is assigned to each mandrel. The transfer devices of a transfer car can either be operated selectively or together, depending on the loading task.

With the help of the control of the travel drive with a computer in accordance with a plug-on pattern of the coil creel it can be achieved, for example, that the transfer carriage is only partially unloaded in a first coil transfer position and partly in another coil transfer position. It is therefore possible, for example, to equip the transfer carriage with bobbins of a single type of yarn, for example a specific one Let the thread color and these bobbins be pushed onto the bobbin winder of the bobbin. As a result, the loading of the trolley can be simplified, because only bobbins of a single type of yarn need to be attached to the trolley. On the other hand, winding positions of all vertical rows of gates can be reached and loaded without the car having to be loaded again before it is completely unloaded in order to be able to do justice to the plug-on pattern.

The device is designed in such a way that the carriage has a chassis that can be rolled on a floor rail and is roll-supported on a ceiling and / or gate-fixed support rail, and that has a remote-controlled drive. With the help of the traction drive, the transfer carriage is moved between its bobbin transfer position in the vicinity of the bobbin winding positions and its bobbin transfer position in the vicinity of the loading device. The process can be computer controlled. The control by the computer takes into account all components of the entire winding system. In particular, of course, the position of the transfer carriage relative to the loading device or the gate must be taken into account, as must its loading condition. The travel drive will not be acted on, for example, as long as the loading device has not yet fully loaded the car. However, the travel drive will not be moved to the gate even if e.g. Rotating frame movements of the gate should lead to collisions with transfer carriages traveling approximately in the direction of the coil transfer position. In addition, the computer can also take into account the running state of the creel or the intended production target.

Due to the simultaneous or overlapping operation of the transfer vehicle and a sleeve removal device on the gate, the time required for the assembly and the sleeve removal process can be minimized. The arrangement of the sleeve removal device at the end facing away from the gate saves space, which can be used, for example, to empty a sleeve collection container of the sleeve removal device while a gate carriage is loading the gate.

The bottom rail expediently has a toothing in which a wheel acted upon by the drive drive engages. As a result, slippage between the transfer car and the floor rail is impossible. The position determination of the transfer car is facilitated.

For determining the position of the transfer carriage, the device is designed in such a way that the chassis is provided with a sensor which influences the travel drive and which responds to gate contacts and / or assembly device-side control contacts which are arranged in accordance with the bobbin transfer positions and / or the assembly position. With the help of the sensor and the control contacts acting on it, the travel drive can be switched off, for example. However, the travel speed can also be reduced, or the travel drive can be switched on again after a predetermined time, provided the transfer carriage has been loaded with full bobbins during its stay at the loading device, or if the transfer carriage has been in the bobbin transfer position during this predetermined time was discharged.

The sensor is a proximity switch and the control contacts are rail elements. These components are conventional and can be easily integrated into the device. They are reliable and allow the transfer cart to be positioned with sufficient accuracy.

A further embodiment of the device with a view to fitting the coil creel in accordance with the sample or with regard to a coil creel that has already been carried out previously can be achieved in that the travel drive and / or the coil slide-over devices are taken into account by a computer, taking into account even before a control and / or or before each coil transfer step, the control contacts and / or the coil transfer device can be controlled. This computer can be identical to or interact with the computer mentioned above. In particular, it allows the spool slide-over devices to be acted upon in such a way that a desired plug-on pattern is achieved. For this purpose, it is neither necessary for the computer-controlled loading of the traction drive nor for the computer-controlled loading of the bobbin transfer devices that sensors are present on the gate which confirm the presence of a full bobbin and thereby influence the control. Rather, the computer can process an assembly sequence provided, taking into account the functions of the sensor and the control contacts, an assembly program specified by it.

The assignment of one impression cylinder to each coil transfer point instead of a single impression cylinder together for all coils in a row of coils makes it possible to dispense with a push rod and the bearings required for this from the single impression cylinder to the coils. Impression cylinders from large series production can be used, which is comparatively inexpensive. Above all, however, the numerous impression cylinders make it possible to transfer individual selected coils, which is important, for example, if only a certain number of winding units are to be re-equipped with coils. This is e.g. the case when some coils of the gate are not fully unwound, or when coils of different colors are to be attached.

The spools can be pushed over in a structurally simple manner in that the impression cylinder has a transversely projecting slide on its piston rod, which engages directly on the spool or on a spool sliding sleeve that can be detached from it as needed and which is displaceable on the mandrel. The engagement of the slide on the sliding sleeve makes it possible to design the device independently of the coil or coil sleeve used.

Furthermore, it is advantageous that the sliding sleeve is displaceable on the mandrel with a roller bearing and / or can be coupled to the mandrel carrier. The roller bearing facilitates the displacement of the sleeve on the mandrel and when the sleeve is coupled to a mandrel carrier, the sleeve is prevented from falling off can, if the associated mandrel carriers point obliquely downwards.

A further development of the device for taking into account different plug-on tasks on the creel is characterized in that the mandrels of the row of mandrels of the transfer carriage are supported in a vertically adjustable manner by a conveying device, and in that this conveying device can be controlled in dependence on a computer which considers a plug-on pattern of the creel for the yarn spools. In connection with a selective pushing of full spools of thread onto the spindles of the creel it can be achieved that the transfer carriage can also be used without problems for unusual patterns. For example, it is possible to quickly populate a single horizontal coil row that only requires a single type of coil. The wagon is fully loaded with this type of spool and unloaded while adjusting its row of mandrels, without the wagon having to be loaded again. This process is also computer-controlled, the computer being identical to the computers mentioned above or being able to interact with them.

In order to move the mandrels vertically, the device is designed in such a way that the conveyor device has two parallel chains which run around deflection wheels arranged with horizontal axes and can be acted upon by the motor drive device and which are connected to one another by mandrel carriers from which the transport mandrels project vertically outwards . Accordingly, the conveyor device consists of elements which have been proven in particular with regard to their durability, and which accordingly guarantee a high degree of freedom from interference. The conveying device can be driven by a conventional electric motor, which can be position-controlled with simple means, so that the positioning accuracy of the transport mandrels relative to the spindles of the creel is problem-free. In particular, the conveyor device can be designed such that it can be driven step by step by the motor drive device with a step size corresponding to the pitch of the mandrels.

If each loaded mandrel in the row of mandrels of the transfer carriage goes up at most into one of the uppermost winding positions of a vertical one Gate row corresponding slide position and downward adjustable at most in one of the lowest winding position of a vertical gate row slide position is ensured that the mandrels do not reach positions in which they undesirably strip the coils. This would be the case, for example, if a mandrel were aligned obliquely downwards by the conveyor. But even if a certain mandrel moves upwards, stripping could occur if the spool rests on the carriage frame, but the mandrel is further adjusted.

The device is particularly advantageous in that, together with it, a sleeve removal device can be moved remotely on a bottom rail, which has a rest position on the take-off side, from which it can be controlled to remove coil sleeves from the row of mandrels furthest from the take-off, from which they remove the coil sleeves is able to remove the winding stations one after the other, and that the transfer carriage can be controlled to the sleeve-free gate rows during operation of the sleeve removal device. Due to the simultaneous or overlapping operation of the transfer vehicle and a sleeve removal device on the gate, the time required for the assembly and the sleeve removal process can be minimized. The arrangement of the sleeve removal device at the end of the gate withdrawal saves space, which can be used, for example, to empty a sleeve collection container of the sleeve removal device while a gate carriage is loading the gate.

Expediently, the travel drive of the tube removal device can also be controlled by a computer which takes into account a plug-on pattern of the bobbin creel for the yarn bobbins, in order to be able to selectively remove at least partially unwound tubes without manual intervention.

It is advantageous that a length measuring device cooperating with the bottom rail or its teeth is provided for the travel drives of the transfer vehicle and / or the sleeve removal device. On the one hand, the length measuring device can be easily formed in a conventional manner by when moving the carriage and the sleeve removal device, for example, longitudinal sections of the bottom rail are counted, for example the teeth of the toothing present on the rail. However, a magnetic length measuring system embedded in the bottom rail can also be used, which enables great accuracy. It is also advantageous that the same length measuring device can be used both for the carriage and for the sleeve removal device.

The coil gates 11 shown schematically in FIGS. 1, 10 each consist of six rotating frames 11 ′, which is symbolized by the circle 50 in FIG. 1. The three rotating frames 11 'shown there form a gate half. The other gate half, not shown, is arranged symmetrically to the dash-dotted line 51. Each rotating frame 11 'is on the inside, ie facing the line 51, equipped with spools 12, from which the threads are drawn off by a winding machine, not shown. The thread group 52 of all the individual threads F drawn off the winding machine runs, for example, as shown, that is to say with an internal draw-off and through reeds, not shown. In the V-gate shown in FIG. 10, the thread is drawn off in a manner not shown on the outside.

The rotating frame 11 'can be equipped on both sides, so that new, full yarn spools 12 can be attached to the side of the rotating frame opposite the thread take-off if the empty bobbin tubes 46 have been removed beforehand.

The bobbin transfer carriages 15, which are shown schematically, are used to plug full bobbins onto the bobbin mandrels 10 of the creel 11 and are loaded with full yarn bobbins 12 by a fitting device 13 in a fitting position 27. The loaded transfer carriage 15 can be moved on a base rail 21 in coil transfer positions 17 in front of the rotating frame 11 ', from where the coil 12 can be pushed onto the mandrels 10 of the rotating frame 11'. On the bottom rail 21, in addition to the transfer carriage 15, a sleeve removal device 44 can be moved, which has a rest position 45, from which it is used in front of the mandrels 10 in order to grip and take over the unwound coil sleeves 46. The interaction of the sleeve removal device 44 and the carriage 15 is explained further below.

For example, configurations of the placement device are described in detail in the parallel German utility model application G 90 10 088.3. 10 shows, in a side view, the principle of such a loading device, with which the full bobbins 12 are transferred to the carriage 15. At a slot 53, the size, weight, packaging,

Type of yarn and the like different coils 12 sorted by an operator at work 54 and brought into the vertical position shown. From there, the spool 12 is brought into the position 12 'shown in dashed lines and placed on a transport mandrel 55 of an endless conveyor, for example by means of a schematically indicated manipulator 56 or also by hand. The mandrels 55 or the like are driven by a revolving chain. to be arranged vertically one above the other in a row of mandrels 58. The mandrels 55 are aligned with the spindles 14 of the transfer carriage 15, so that the coils 12 conveyed into the row 58 via the head 57 of the insertion device can be pushed onto the mandrels 14 of the carriage 15. This pushing takes place in the manner shown in FIG. 1 in the direction of arrow 59 with a remote-controllable actuating device, which is symbolized by arrow 60.

The mandrels 14 of the carriage 15 form at least one vertical row of mandrels 18, which has a pitch t corresponding to the pitch T of the coil mandrels 10, cf. Fig. 5. The carriage 15 holds the mandrels 14 at a height at which they are aligned with the spool 10. As a result, it is possible to populate the bobbin mandrels 10 by simply pushing the bobbins 12 over the mandrels 14. For this purpose, the carriage has 15 spool transfer devices 19, each such device 19 being assigned to a mandrel 14 in parallel. The device preferably consists of a coil impression cylinder 28, which carries a slide 30 on a piston rod 29, which serves to push the coils 12 off the mandrel 14. For pushing, all impression cylinders are acted on simultaneously, for example by compressed air, or selectively, for example to load them according to the sample. A spool sliding sleeve 31 is arranged on the mandrel 14 and engages around the mandrel with the interposition of a roller bearing 33 designed as a spherical bushing. The latter is fastened to the sliding sleeve 31 and reduces its sliding resistance when actuated by the slide 30. Thus, the sliding sleeve 31 in both directions of the mandrel 14 can be moved, it has an incision in the form of an annular groove 59, in which the slider 30 engages. The sliding sleeve 31 is provided with a sliding flange 60, the outer diameter of which is larger than the largest possible Sleeve diameter so that the coil 12 can always be moved on its sleeve 12 '.

In the cases of the differently designed carriages 15 of FIGS. 2 to 4 on the one hand and 5 to 7 on the other hand, the coil transfer device 19 can be of the same design. In the case of the carriage of FIGS. 2 to 4, a special cylinder arrangement could be chosen instead of the spool transfer device 19 shown, which is coaxial with the mandrel 12, the mandrel being an extension of the piston rod of this cylinder arrangement.

The transfer carriages 15 shown in the figures each have a vertical housing 61 to which the mandrels 14 are attached directly or indirectly. The housing 61 is rigidly connected to a chassis 20 which has two castors 62 which can be rolled on the floor rail 21 and the housing 61 is supported in a laterally guiding manner. You transfer the weight of the carriage 15 to this floor rail. The latter is arranged parallel to the gate 11 on the outside of the gate. A horizontal support of the carriage 15 takes place with a support roller 63 vertically at the top on a ceiling and / or gate-fixed support rail 22, against which the support roller 63 bears due to the corresponding load of the housing 61.

The carriage 15 is driven by a controllable travel drive 23, which consists of an electric motor 64, which by means of a chain 65 drives an output gear 66 of a reduction gear, which engages with a gear 24 in a toothing of the bottom rail 21. The travel drives 23 of the two illustrated embodiments of the carriage 15 are slightly different, but can be controlled remotely in both cases. The engagement of the wheel 24 takes place in a rack 66, with which the bottom rail 21 is provided. The drive motor 64 can be controlled so that the carriage 15 is positioned sufficiently precisely horizontally with respect to the mandrel 12 of the gate 11. If necessary, a sensor 25 located on the chassis 20, which interacts with a control contact 26 of the floor rail 21, is used for this purpose. This contact 26 is for example a fastening screw of the rack 66. It can also be a additional contact 26 'can be used as a pre-contact, for example in order to reduce the driving speed of the carriage 15 so that it can be stopped immediately when the position determined by the contact 26 is reached. For precise positioning, it is often necessary to adjustably attach sensor 25, which is designed, for example, as a proximity switch, to chassis 20.

The transfer carriage 15 of Figures 2 to 4 is of simple construction. Its housing 61 has a rectangular cross section for reasons of stability. The impression cylinders 28 are fastened to the outside of the housing in a manner not shown. The mandrels 14 are fixed to the frame. They are also not adjustable in height. Such a simple design of the carriage 15 enables a large percentage of assembly tasks to be performed. It is always used when vertical rows of uni are loaded, or when auxiliary means are available on the assembly device for fitting the coil gate in accordance with the pattern in order to equip the mandrels 14 as required by the coil mandrels 10 of the gate 11. Such aids are, for example, selectable coil suppliers, such as conveyor belts or round magazines, and computers which indicate to the operator which coil is to be placed on which mandrel 14. Such tools can be used, but are undesirable in principle. Coil delivery devices, in particular, require construction and space and require the operator to be adapted to the assembly process while using the coil delivery devices and taking into account the computer.

To relieve the operator, it is therefore desirable to equip all the mandrels 14 of the carriage 15 with bobbins of the same type of yarn. In order to make this possible in particular, the carriage 15 is designed in a special manner according to FIGS. It has a conveying device 34 for the mandrels 14. The conveying device 34 essentially consists of two parallel chains 38, each guided over two deflection wheels 36, which have the same distance from one another over their entire length. The chains 38 are connected to one another according to FIG. 8 by mandrel carriers 39, of which the mandrels 14 point radially outwards. The of the orbit 67 described at the tips of the mandrels 14 is shown in broken lines. Within the frame 61, the mandrels 14 point away from the gate 11.

The deflection wheels 36 are designed as gear wheels and have horizontal axes 35 which run parallel to the gate. The upper pair of deflection wheels 36 is connected in a rotationally fixed manner to a coaxial drive wheel 68, which is driven by a drive device 37 via a drive chain 69 and, as a result, is capable of rotating the mandrels 14 of the vertical row of mandrels 18. The drive device 37 of the chains 38 can be controlled in such a way that the mandrels 14 can only be adjusted to a limited extent if they are equipped with coils 12. Each loaded mandrel 14 can at most be transported upwards into a slide-over position 41, which is opposite the uppermost winding point 49 of the row of gates 40. The mandrels 14 can at most be adjusted downward into a sliding position 43, which corresponds to the lowest winding position 42 of the gate 11.

With the aid of the conveyor device 34, it is possible to equip all the mandrels 14 in uni and to push the full bobbins 12 in accordance with the pattern requirements of the gate 11. For example, only the top horizontal row of coil mandrels 10 of the gate 11 can be equipped. It is of course necessary that the positioning of the mandrels 14 is controlled. This control can, however, be carried out by a computer which determines the control program for the carriage 15, taking into account the plug-on pattern for the gate 11, if appropriate, taking into account those coil mandrels 10 which have already been fitted during a loading run of a carriage 15. The operator need not be switched on for this.

So that the mandrels 14 can be adjusted vertically, even though the push-over devices 19 are fixedly arranged on the frame 61, the slide 30 is detachably connected to the spool sliding sleeve 31. For this purpose, it engages with its end in the annular groove 59 of the sliding sleeve 31, so that it can be adjusted vertically with the spikes 14 relative to the vertically fixed sliders 30. To prevent that from the slide 30 held sliding spool sleeves 31 can slide down from the mandrel 14, if the latter is directed obliquely when the conveyor is adjusted, 39 magnetic holding plates 31 'are arranged on the mandrel carriers.

It can be seen from FIG. 10 that the carriages 15 can be moved according to the arrows 70 in the coil transfer positions 17 near the rotating frame 11 'of the gate 11. Empty coil mandrels 10 can then be equipped with coils 12. Thereafter, the carriages 15 must be moved out of the area between the rotating frames 11 ', on the one hand to enable the rotating frames 11' to be rotated, and on the other hand to be re-equipped. The arrangement shown is only for example. Taking into account the existing gate designs, numerous other possibilities for equipping with carriages 15 are conceivable.

The gate design described in FIG. 1 shows the sleeve removal device 44 in its rest position 45 as a special feature. When the bobbins 12 of the rotating frame 11 'are unwound, the rotating frame 11' is turned so that the empty bobbin sleeves 46 face the bottom rail 21. The sleeve removal device 44 is then moved into its first working position 71, in which its transport mandrels 72 lie opposite the mandrels 10 of the mandrel row 73 of the gate 11 pointing outward from the gate. The sleeve removal device 44 takes over the empty sleeves of this row of mandrels 73 and conveys them into a sleeve collecting container 74, in that their mandrels 72 are conveyed by an endless conveyor similar to the conveying device 34 of FIGS. 5 to 7 into a position in which the sleeves 46 are moved by gravity into the Slip the sleeve collecting container 74. In the meantime, the device 13 can be moved from one row of mandrels to the next row of mandrels. This results in a considerable time saving. The exact description of such a sleeve removal device 44 can be found in the simultaneous German utility model application G 90 10 089.1.

After the sleeves 46 have been removed from the mandrels of the mandrel row 73, the device 44 becomes the mandrel row of the working position 75 controlled etc. until all sleeves 46 of the rotating frame 11 'are removed. The device 44 then returns to its rest position 45.

The transfer carriage 15 is first shifted from its rest position or loading position 27 to the row of mandrels 73 in order to transfer all or part of the spools 12 there. It is controlled so that it does not collide with the sleeve remover 44. For this it is not necessary that the latter has already returned to its rest position 45. Rather, it is sufficient if the device 44 allows the carriage 15 to be moved into its first coil transfer position 17, shown in FIG. As a result, the step-by-step assembly of all vertical rows of all rotating frames 11 ′ shown in FIG. 1 results in a time overlap with the removal of empty bobbin tubes 46 by the tube removal device 44. The removal of empty tubes 46 and the loading of fully wound bobbins 12 can take place during the thread withdrawal from the Line 51 facing coils take place so that downtimes are avoided.

11 shows a two-line rotating frame gate 11, similar to FIGS. 6, 7, with two loading devices 13. The thread groups 80 are pulled off from the inside of the rotating frame 11 'on both sides. These are arranged with control stations 37 or 37 'essentially in alignment between the two lines of the rotating frame gate 11. Each assembly device 13 interacts with an assembly carriage 15, which can be moved on the outside of the rotating frame 11 'on a floor rail 21. The pick-and-place carriage 15 has transport mandrels 76 for receiving full spools of thread 12, which are transferred from the pick-and-place device 13 in the direction of arrow 77 by pushing them onto the mandrel 76 of the carriage. After a vertical row of mandrels 76 has been fitted, the carriage 15 is moved to a row of coil mandrels 10 to be fitted, after which the full bobbins 12 are pushed onto the rotating frame 11 'by the fitting carriage 15. A device which is similar to that of the loading device 13 serves for pushing over. Furthermore, a sleeve removal device 44 can be moved on the bottom rail 21 in order to remove empty bobbin tubes from the bobbins 10 to remove the gate 11.
