EP0410021B1 - Process and apparatus for automatically replacing bobbin adaptors loaded with empty bobbins by bobbin adaptors loaded with full bobbins at the processing station of a textile machine - Google Patents

Description

The invention relates to an operating method and a device according to the preamble of claims 1 and 4. Such a method and device is known, for example, from DE-A-3 824 998.

As with all types of textile machines, there is also a twisting machine, e.g. Double-wire twisting machines, the general desire to automate certain work processes and thus in particular the exchange of empty or almost empty bobbin tubes for fully wound supply or delivery bobbins.

For example, EP-A-0 310 567 deals with a device for exchanging fully wound coils or bobbins for empty tubes with a first endless conveyor designed as a hanging conveyor device, a first transfer element and a second endless conveyor also designed as a hanging conveyor device. The first transfer element, which is arranged essentially stationary between the two endless conveyors, can be moved up and down, can be moved back and forth horizontally and can be pivoted about a vertical axis and is used to individually empty tubes from the first endless conveyor to the second endless conveyor and vice versa individual bobbins from the second Continuous conveyor to be handed over to the first endless conveyor. The bobbin-tube exchange or exchange between the second endless conveyor and the spinning machine is carried out field by field by means of a further transfer element.

In addition to the basic task of automating the bobbin / tube exchange or exchange, this document deals with very special construction elements and measures that make the known system unsuitable for double-wire twisting machines for the individual exchange of empty bobbin tubes against fully wound supply bobbins.

DE-A-1 932 014 relates generally to a method and an apparatus for improving the efficiency of the operation of spinning machine halls, and relates in particular to a thread monitor or thread twisting device in combination with a pneumatic cleaning device. For this purpose, a cleaning device which can be moved along an upper rail is provided. This document does not contain any information referring to a bobbin / tube exchange or exchange. From the general endeavor to automate the operation of ring spinning machines, in particular insofar as it relates to the operation of a pneumatic cleaning device in connection with thread monitor and thread turning devices, no suggestion can be drawn as to how a method and a device for bobbin / sleeve exchange in a double-wire Thread spindle is to be designed.

DE-A-2 811 128 deals with an automatic bobbin changing device for exchanging fully wound bobbins for empty tubes. It is an automatic bobbin changing device which can be moved along a yarn processing machine and with which a predetermined number of full bobbins can be exchanged for empty tubes. A maintenance carriage that can be moved on floor rails and a spinning sleeve carrier that can be moved on another rail are provided for a specific number of empty tubes. A spinning tube holder is provided for handling the empty tubes, while separate head holders 201 are provided for handling the heads. The sleeve holder and the bobbin holder have their own handling and Actuating rods, the constructions and functions of which cannot be transferred to a double-wire twisting machine.

The system according to the preamble of claims 1 and 4, which relates to a double-wire twisting machine and is described in DE-A-3 824 998, requires the supply of fully wound supply bobbins on the one hand and the removal of empty or almost empty bobbin tubes in the lower spindle area, which means that the distance between the row of spindles and the front side of the double-twisting machine which is freely accessible to an operator is considerably increased. As a result, maintenance work in the spindle area that is to be carried out manually by an operator is made considerably more difficult.

The invention has for its object to provide an operating method and an apparatus for the automated replacement of bobbin adapters equipped with empty sleeves for bobbin adapters equipped with full supply bobbins for the maintenance of a double-wire twisting machine, in particular with relatively large horizontal and vertical distances between the individual double-wire twisting spindle and a feed device designed as a hanging conveyor device for spool adapters equipped with fully wound supply spools without significant expenditure of time and effort. According to the invention, care should essentially be taken to ensure that the individual work steps during the tube and spool exchange are carried out in parallel as far as possible, i.e. be carried out in time.

Starting from the method or the device according to DE-A-3 824 998, this object is achieved by the features of the characterizing part of claims 1 and 4.

Preferred embodiments of both the operating method according to the invention and the device according to the invention are dealt with in the further subclaims.

The overhead conveyor device C comprises a top rail 3, in which a conveyor chain or a conveyor belt is guided, on which or at which the bobbin hanging holder 4 for bobbin adapters or bobbin transport adapters 5 hanging down at regular intervals are fastened. The bobbin hanging holder 4 and the bobbin adapter 5 are designed in a known manner so that when a bobbin adapter 5 is started up, the bobbin adapter is gripped and held by the bobbin hanging holder, while the bobbin adapter 5 is released by the bobbin hanging holder 4 during the subsequent raising and lowering thereof. Fig. 1 shows in the area of the top rail 3 on the left side six bobbin adapters 5 each equipped with two fully wound cross-wound bobbins or feed bobbins 6, which are to be transferred to the individual twisting points of the double-wire twisting machine 1 by means of the maintenance machine B, and two on the right with empty sleeves 6 ′ equipped bobbin adapters 5, which have been individually removed from the twisting points of the double-wire twisting machine A by the maintenance machine B and transferred to a bobbin hanging holder 4. These sleeves 6, which may still have thread rest windings, are conveyed together with the spool and transport adapter 5 by means of the overhead conveyor device C to an external loading station, in which the adapters 5 can again be loaded with fully wound supply spools or cross-wound bobbins 6. The supply spools can also be specialist spools.

The double-wire twisting machine A comprises several work or twisting points with the usual known elements such as (not shown) spindle in the lower area, balloon limiter 7, bobbin pot 8, thread inlet 9, balloon thread guide 10, deflection elements 11 for controlling the thread opening tension, advance line 12, traversing thread guide 13 and the cross-wound spool or take-up spool 15 driven by a friction roller 14. In the middle of the machine, in the upper area between the two parallel machine sides, there is a conveyor belt 16 for the removal of fully wound cross-wound bobbins 15. Above each cross-wound spool or driven by a friction roller 14 The package 15 is a sleeve magazine 17 for empty bobbins 18th

An upper, only partially wound cross-wound bobbin or feed bobbin 6 of a feed bobbin pair inserted into the twisting point by means of a bobbin adapter 5 is shown inside the protective pot 8. The threads are drawn up from the supply spools and passed through the thread inlet 9 into the lower spindle area to a thread storage disk, from which the two combined threads run to form a thread balloon to the balloon thread guide 10 and then after passing through the guide rollers 11 and the lead 12 on the be wound by the friction roller 14 driven reel 15.

The maintenance machine B patrols in front of the double-wire twisting machine A or the individual twisting points. Fig. 1 shows schematically and in sections various handling elements of the machine B, which are used to replace a bobbin adapter 5 (drain unit) equipped with empty bobbin tubes 6 'with a full bobbin 6 Equipped bobbin adapter 5 (template unit) and for manipulating or securing the thread ends of the empty or almost unwound bobbin tubes 6 '. These are mainly two holding mandrels 100, which can be pivoted about a vertical axis and can be moved up and down in the vertical direction, for supply and discharge units as well as gripper and suction devices 22 and 23.

The maintenance machine B has a cabinet-shaped housing 101, the front wall of which has a guide rail 102 for the mandrel 100 pivotable cross arm 103 is provided.

In addition to the structural details, the modes of operation and functions of the individual elements according to the invention are also described below.

Fig. 2 shows a double-wire twist spindle additionally the bobbin bottom 8.1 and the usual thread storage disk 19. The bobbin adapter 5, which is also transport adapter in the manner described above, consists of a cylinder section 5.1, which has a supporting flange 5.2 at its lower end and Area of its upper end preferably has an annular groove 5.3. The gripper 22 of the maintenance machine B, which has the two gripper arms 22.1 and 22.2 and can be pivoted in the horizontal direction (arrow f1) and can be moved up and down, is used to remove the drain unit from the double-wire twisting spindle. The gripper ends of the two gripper arms 22.1 and 22.2 can be used in the Spindle pot 8 inserted bobbin adapter 5 on its outer circumference, but preferably in the area of its annular groove 5.3, tightly enclosing, which at the same time the end of the not yet fully expired lower bobbin tube 6 'coming into the hollow core of the bobbin adapter is automatically clamped and secured. When removing the bobbin adapter 5 from the bobbin 8 by raising the gripper 22, care must be taken to ensure that the thread end is pulled out of the hollow axis of the spindle without any hindrance by automatically opening a thread brake arranged in a known manner inside the spindle hollow axis of the double-wire twisting spindle can be.

According to FIGS. 2 and 3, a two-part coil adapter is assumed. The lower section of the adapter represents a means of transport for the fully wound bobbins or the expired tubes. In this form, it is also part of the bobbin transport system superior to the double-wire twisting machine. On the double wire twisting spindle, i.e. inside the bobbin, such an adapter lower part 5 also serves to center the bobbins on the hub of the bobbin.

On this adapter lower part 5 is a hollow part having a head part or adapter upper part 5 ', which is used in a known manner to create different thread drainage conditions on a double-wire twisting spindle. The adapter upper part 5 'can, for example, be a threading head forming Avivier device of a known type for wetting the thread running through with a finishing agent. Fig. 2 shows a section of the double-wire twisting machine in cross section, namely the machine frame 27, a compressed air line 28 with a connection 29 leading to a double-wire twisting spindle, which leads to a compressed air nozzle 30 for the pneumatic threading, and a spindle whorl 31 with belt pressure roller 32 for pressing a tangential drive belt 33 against the spindle whorl 31. A foot lever 34 assigned to each individual spindle serves to actuate a spindle brake, not shown, and this foot lever 34 also serves to actuate the compressed air nozzle 30, in order to build up a suction air flow in the spindle hollow axis for the purpose of threading the thread through the spindle in a known manner.

2 further shows partial areas of the maintenance machine B patrolling in front of the double-wire twisting machine along the rails 1 and 2, of which sections of the maintenance and handling elements relevant to the invention and / or the further description are shown, such as the gripper 22 and the suction device 23, and an actuating lever 35, by depressing it in the direction of arrow f6, the foot lever 34 can be actuated at the given moment to stop the individual spindles. 2 shows just above the foot lever 34 two rollers 36 of the maintenance machine B, which are guided along a guide surface 1.1 of the lower rail 1.

The suction device 23, like the gripper 22, can be pivoted in the direction of the arrow f1 and can be moved up and down in the direction of the arrow f5 in the vertical direction.

2 it should also be mentioned that when the suction device 23 is pivoted into the region of the spindle axis, the balloon thread guide 7 is pivoted out of its coaxial position to the spindle.

Fig. 3 shows the gripper 22 as it grips with its two gripper arms 22.1 and 22.2 of the adapter lower part 5 and at the same time that which still has a residual winding Sleeve 6 'leading thread end clamps.

The adapter upper part 5 'is held by an attached to the suction device 23, upper gripper 37, which has two gripper arms 37.1, 37.2 pivotable in the horizontal direction. While the two looper arms 22.1 and 22.2 of the lower looper 22 are able to come to rest over their entire inner circumference against the outer circumference of the adapter lower part 5 or the annular groove 5.3, so that a thread end is independent of its circumferential position relative to the adapter. Bottom part is clamped, the gripper arms 37.1, 37.2 of the upper gripper 37 are provided with inwardly directed projections or lugs 38, which engage in punctiform fashion when the gripper arms are closed in an annular groove 5.1 'of the adapter upper part or thread inlet head 5', without one at the Clamp the outside of the adapter upper part 5 'along the thread.

In the lower gripper 22 or in its gripper arms 22.1 and 22.2 and in the suction device 23, air lines not belonging to the present invention are integrated, through which compressed air can be supplied either for the pneumatic actuation of the gripper arms or cutting devices, not shown, or in which a suction air flow is built up can be used to suck off cut thread ends. For the present invention, it is essential in the region of the adapter lower part 5 to clamp the thread end winding of one of the two sleeves 6 'leading thread end in the manner shown in FIG. 3 by means of the gripper arms 22.2, 22.2 of the lower gripper 22.

After the state shown in FIG. 3 is reached, the suction device 23 is pivoted laterally together with the upper gripper 37. Then the adapter lower part 5 together with the two sleeves 6 'can be lifted out of the coil pot 8 by means of the gripper 22. The gripper 22 is then pivoted into the maintenance machine B so far that the adapter lower part 5 with the two sleeves 6 'can be attached to one of the two mandrels 100, which has been brought into a corresponding pivot position.

2 shows, in addition to the lower thread gripper 22 and the suction device 23, partly in the lower and partly in the upper lifting positions, the swiveling and lifting device 99 according to the invention for the exchange of bobbin or transport adapters equipped with empty bobbin tubes for bobbin adapters equipped with full supply bobbins.

4 shows a state in which a bobbin and transport adapter 5 equipped with fully wound supply bobbins 6 is lowered into a spindle or a spindle-bobbin. This adapter 5, which is equipped with full supply coils 6, has previously been removed from the arbor 100 located within the automatic maintenance machine B. In Fig. 5 outside the maintenance machine B a with the two empty or almost empty coil sleeves 6 'equipped coil and transport adapter 5 is shown. This is located outside the maintenance machine B. Spool adapter is moved in the direction of arrow f7 upwards into the area of the overhead conveyor C in order to transfer the drain unit, consisting of spool adapter 5 and the two empty spool sleeves 6 ', to an empty spool holder 4 for removal.

In the case shown, two cross-wound bobbins 6 are accommodated on a bobbin or transport adapter 5. When this package of cross-wound bobbins is presented in a double-wire twisting spindle, it is known that the specialist process takes place when the threads run on the twisting spindle. The bobbin or transport adapter could, however, also be equipped with a specialist bobbin. Although in the present case the mode of operation of the device according to the invention is described with reference to two single-wound cross-wound bobbins, it is also possible to start with specialist bobbins instead, since the handling does not differ between single-wound cross-wound bobbins and specialist wound bobbins.

3, namely the gripping of the adapter 5 with two empty or almost empty coil sleeves 6 'and if necessary the lifting of the adapter upper part 5' from the adapter-adapter lower part 5 is also carried out by means of the in the automatic maintenance machine B integrated swivel and lifting conveyor 99, a full package of bobbins (transport adapter 5 with full cross-wound bobbins 6) is unhooked from the overhead conveyor and transported into the lower area of the machine B. At the same time, the suction device 23 with the upper gripper 37 is together with that of it held adapter upper part 5 'pivoted back into the machine, so that from the lower gripper 22, the adapter lower part 5 including the expired sleeves 6' lifted out of the coil pot and can also be pivoted into the machine. The expired package of bobbins is placed by this lower gripper 22 onto the arbor 100 located inside the automatic maintenance machine B. This state is shown in Fig. 6.

According to FIG. 6, both swivel arms 103 with their holding mandrels 100, not shown in FIG. 6, assume their lowest position, one swivel arm 103 carrying a template unit (coil adapter 5 with full cross-wound bobbins 6) being outside the maintenance machine, while the other swivel arm 103, on the mandrel of which a drain unit (coil adapter 5 with empty sleeves 6 ') has been plugged in by means of the gripper 2, is located inside the maintenance machine B. By pivoting the two swivel arms 103 according to the arrows f7, the swivel arms reach the position shown in FIG. 4, so that a full template unit 5, 6, 6 can now be gripped by means of the gripper 22 and inserted into the bobbin while an empty drain unit 5.6 ', 6' for the purpose of transferring the coil adapter 5 to the overhead conveyor C can be promoted upwards.

The swiveling and lifting conveyor device 99 contains, in the region of its swiveling part, a rotating head 104 which is rotatably mounted about a vertical axis and which has a drive disk 104.1 and a hub part 104.2. The rotary head 104, which is provided with an axial, continuous opening, can be set in rotation by means of an electric motor 105. This electric motor 105 drives a control disk 106, which always causes a movement of the rotary head 104 by 90 ° or 180 ° via a lever mechanism 107 and a toothed belt 109 driven horizontally from the lever end, which is placed around the drive disk 104.1 and a drive pinion 108 . The position of the rotary head 104 shown in FIG. 5 corresponds to the position according to FIG. 1 and thus the driving state of the automatic maintenance machine B, the two swivel arms 103 mounted on the rotary head and thus also the sleeve mandrels 100 lying in one plane parallel to the direction of travel of the automatic maintenance machine .

The rotary head 104 has, in the area of its hub part 104.2, the diametrically opposite guide rail sections 104.3, which serve to position and guide the swivel arms 103. For this purpose, each swivel arm 103 is provided in the area of a vertical leg 103.1 with inwardly directed pairs of rollers 110, which are held on the one hand by the guide rail sections 104.3 and on the other hand can be rolled along these guide rail sections 104.3 in the vertical direction.

The lifting conveyor part of the swiveling and lifting conveyor device 99 is designed in the manner of a vertical elevator and, in addition to a drive device, comprises a vertical rail 111 which is stationary within the maintenance machine B and whose profile corresponds to the profile of the Corresponds to guide rail sections 104.3. Along this vertical rail 111, a towing vehicle 112 can be moved up and down in the vertical direction by means of pairs of rollers 113 guided along the vertical rail 111. This towing vehicle 112 is fastened to a traction conveyor belt 114 which has a run parallel to the vertical rail 111, such that the towing vehicle 112 can be moved along the vertical rail 111 by moving the traction conveyor belt 114 up and down. In the illustrated embodiment, the tension conveyor belt 114 is a toothed belt which is guided over toothed pinions 119.

A lifting cylinder 115 is used to drive the pulling conveyor belt 114, which receives in its interior a lifting piston, not shown, to which a plate 116, which is led out laterally from the lifting cylinder 115, is fastened. Deflection rollers 117 configured as toothed pinions are fastened to this plate at a vertical distance above one another, via which the end sections of the tension conveyor belt 114 are looped around, while the ends of the tension conveyor belt are fastened to brackets 118. The traction conveyor belt 114 wraps around the deflection rollers 117 in the manner of a pulley block in such a way that a lifting movement a of the plate 116 corresponds to the double lifting movement 2a of the towing vehicle 112 attached to the traction conveyor belt 114.

The towing vehicle 112 is provided with an inward-facing, laterally open undercut 112.1, into which, when the towing vehicle 112 is at a corresponding height, an undercut directed outwards Claw 120 is laterally insertable at the upper end of the vertical leg 103.1 of the swivel arm 103. It is within the scope of the invention to design the coupling members on the towing vehicle 112 and on the swivel arms 103 also differently, as long as it is ensured that when one of the two guide rail sections 104.3 of the rotary head 104 is aligned with the vertical rail 114, a coupling connection between the towing vehicle 113 and the respective swivel arm 103 can be created, so that when the towing vehicle 113 moves upwards, the corresponding swivel arm 103 is pulled upward from its guide rail section 104.3 and transferred into the region of the vertical rail 111.

The coupling members between the towing vehicle 112 and the individual swivel arms 103 are shown in the disengaged position in FIG. 5 and in FIG. 6 for the one swivel arm 103 in the latched-in position in which the claw 120 engages in the undercut 112.1 of the towing vehicle 112. The claw 120 and the undercut 112.1 are designed such that, when the towing vehicle 112 is lowered, the claw 120 can move laterally into the undercut 112.1 when the rotary head 114 rotates.

The central opening already mentioned above, which passes through the rotary head 104, serves, according to FIGS. 5 and 6, for the passage of the conveyor belt 114. As soon as the one swivel arm 103 is latched into the towing vehicle 112, this swivel arm 103 can be moved upwards by the towing vehicle 112 during its upward movement be taken to to convey a discharge unit plugged onto the holding mandrel of this swivel arm 103 and to transfer it to the overhead conveyor.

The movement sequences of the individual maintenance and handling elements of the maintenance machine B are as follows:
While the grippers 22 and 37 swivel out of the maintenance machine into a position coaxial to the spindle axis, and while according to FIG. 3 the separation between the adapter upper part 5 'and the adapter lower part 5 is carried out, a full package of coils is made by means of the lifting conveyor Hanging conveyor unhooked and transported to the lower area of the machine. At the same time, the upper gripper 37 with the adapter upper part 5 'is pivoted back into the machine, and the lower gripper 22 has then the adapter lower part 5 including the expired sleeves 6' lifted out of the bobbin and is also in the machine pivoted in that this drain unit is plugged onto the mandrel 100 located inside the machine. The two swivel arms 103 are fixed to the rotary head 104 at this time, so that the two swivel arms 103 interchange their positions with one another by a subsequent rotary movement of the rotary head by 180 °. The swivel arm 103 carrying the drain unit 5,6 ', 6' is latched into the towing vehicle 112, so that this swivel arm 105 can be moved upwards for the purpose of transferring the drain unit to the overhead conveyor, while at the same time the template unit 5,6,6 of the located inside the machine Swivel arm 103 can be lifted off and inserted into the bobbin case. Then the adapter upper part 5 'is placed on the adapter lower part 5 by means of the upper gripper 37.

The device according to the invention also comprises a pneumatic or hydraulic damping unit 121 in the area of the lifting cylinder 115 in order to resiliently absorb the upward and downward movements of the piston or the plate 116 of the lifting cylinder 115 in the area of its end points. The lifting cylinder 115 works against the force of the damping unit 121, so that the lifting movements are braked, thereby enabling the towing vehicle and the swivel arm 103 clipped therein to be moved into the end positions. This process applies to the unhooking of a fully wound supply reel 6 comprising the subunit from the overhead conveyor as well as for the hanging of a drain unit in the overhead conveyor and also for the pivoting arms 103 in the end position on the rotary head 104.
