Definitions
- the invention relates to a method and an apparatus for securing the roving end torn off between the winding winding and pressing finger during the automatic bobbin changing on roving machines on a winding of the full roving bobbin.
- Coil transport e.g. from roving bobbins to a spinning machine, is carried out automatically in modern spinning mills with a transport system in which these bobbins are transported in groups or individually overhead.
- the coils are usually carried by hanging pegs, which are attached to coil trains that are guided in a rail system via a drive system.
- a drive system Such a system is e.g. can be seen from EP-OS 392482.
- an adhesive strip was applied to secure the outer winding layers of the coil in the area of the head shoulder. It has been proposed to use this adhesive strip e.g. to apply with a spray gun. The application of this adhesive strip on the head shoulder is intended to exert sufficient retention force on the outer turns of the yarn to ensure that if the withdrawal of the yarn from the bobbin is interrupted, the reduction in tension during the withdrawal is not transferred to the yarn of the bobbin becomes.
- the type of securing the outer bobbin winding is used especially for yarn bobbins, which serve as a template for a subsequent processing process.
- attaching an adhesive strip in this form is not suitable for securing the sliver end of a roving bobbin. As a rule, the sliver end is located between the two conical ends of the coil. This means that attaching an adhesive strip to a cone part would not be able to prevent a partial unwinding of the outer turns.
- a method is proposed in which at least the last turn of the roving end located on the bobbin is brought into a releasable adhesive connection by means of an additional means on at least a partial area of its circumference with at least one adjacent turn.
- the additional agent can be an adhesive that is rolled up, dabbed on or sprayed on.
- the adhesive By means of a selected spray pressure between 3 and 5 bar and a corresponding distance between 10 and 20 mm from the surface of the spool, the adhesive can be sprayed on in appropriate doses without causing damage to the roving wound on the spool. This means that the adhesive connects the second to last turn with the third and last turn. However, the adhesive should not reach the bottom, that is, the penultimate layer.
- the punctiform application of the adhesive is not sufficient, it is proposed to rotate the coil about its longitudinal axis and / or to shift it in its longitudinal axis while the adhesive is being applied.
- This longitudinal displacement could also be carried out by moving the adhesive device. As a result, the application area is enlarged somewhat and the sliver end is in any case gripped by the adhesive.
- the longitudinal displacement can also compensate for tolerances in the storage position of the roving end on the bobbin.
- the additional agent adheresive
- the coil can be aligned in a predetermined position if the spraying is carried out with freely suspended coils.
- a corresponding spraying device can be easily assigned to the coil, especially since the spraying device and the coil surface are at a fixed distance during the transfer over a certain time.
- the adhesive can also be applied, for example, in the area immediately after the transfer device if the coil is already on the second transport system.
- the discontinuous transport of the coils during the transfer process is used. This means that every time the transport device has been moved by one step or a mounting spigot after a bobbin handover, the next bobbin to be secured takes a stop position in a positioned position with respect to a spray gun, in which the adhesive is sprayed on, until the next transport step can.
- a coil In combination with match sticking, a coil can be identified by adding a dye.
- This dye which can also be a marking dye, is mixed in a certain ratio with the addition of wetting agent and is water-soluble and washable.
- This dye can be mixed with the adhesive before or during application to the spool.
- the application device can consist of a nozzle of a spray gun which is at a distance from the coil surface and which applies the adhesive to the coil in the area of the last turn.
- a water-soluble adhesive In order to avoid adverse effects on subsequent processing processes, such as color defects in the fabric, it is proposed to use a water-soluble adhesive.
- the spray gun is attached to a pivotable arm, which is used to transfer the coils is provided between the transport devices, the time interval in which the spray gun and the coil surface assume a fixed position can be increased. This means that the adhesive can be applied during the swiveling process.
- the spray gun For a more variable adaptation of the spray gun to the circumference of the coil, it is also proposed to attach it coaxially to an axis of rotation of a pivotable arm. This makes it possible for the spray gun to be able to move with respect to its position relative to the surface of the coil during the spraying operation, and thus to allow the adhesive point to be enlarged in the circumferential direction of the coil. Instead of moving the spray gun, the use of a second spray gun is also conceivable.
- the further proposal to mount the applicator device or the spray gun in a height-adjustable manner enables an adaptation with respect to the longitudinal axis of the coil and, on the other hand, enables the application of more than three turns lying side by side with an adhesive layer.
- This height adjustment can also be carried out via a drive, as a result of which a specific vertical region on the surface of the spool can be wetted during the application process of the adhesive.
- This shielding device can consist, for example, of an annular air duct which is generated in the spraying direction of the nozzle by a second air nozzle assigned to the spray nozzle.
- the spray gun can be assigned a switchable or deliverable cleaning device.
- a cleaning device for example, a rotating brush that can be fed to the outlet of the nozzle could be used.
- Cleaning is not only to be understood to mean the removal of external contaminants which get into the area of the nozzle, but also the cleaning of the application device or spray gun itself. This is particularly necessary when a paint substance is added to the adhesive in the spray gun and the change to a different color substance is desired.
- the mixing chamber inside the spray gun must be cleaned of the old paint substance with an additional solvent.
- the solvent is introduced into this mixing chamber and sprayed with the dissolved parts from the nozzle of the spray gun onto a collecting device.
- This collecting device could, for example, consist of a collecting container that can be fed to the nozzle.
- Figure 1 shows a schematic top view of a roving machine, e.g. a flyer 1 and a spinning machine, e.g. a ring spinning machine 2, which are connected to one another via the bobbin transport devices 3 and 4.
- the transport device 3 on the flyer 1 is also generally referred to as a flyer doffer.
- the transport device 3 serves to receive the full bobbins 5 delivered by the flyer 1 and also to return empty sleeves to the flyer 1, which have been transported back by the ring spinning machine 2. In the example shown, the delivery of only ten coils 5 is shown. In practice, however, there are significantly more coils that are released for further transport.
- the details of the transport systems 3, 4 are not shown in detail.
- the transport system could be, for example, elements guided in rails with pick-up pins for the coils, as shown, for example, in EP-OS 394708.
- the drive, which is used to move the coils 5 within the transport systems 3, 4, is shown schematically with the position 24 and the control unit 25 in the transport system 4. In the transport system 3, only the control unit 26 for the output is indicated.
- the transfer device 6 is shown on an enlarged scale and will now be described in more detail.
- the telescopic arm 7 is mounted about a vertical axis of rotation 9 with a shaft 10 pivotable by 90 °.
- the shaft 10 is rotatably mounted in a frame 11 fixed to the floor and axially immovable.
- the telescopic arm 7 is slidably mounted in the vertical direction via a cylinder 13. This vertical movement is monitored by limit switches 14, 15, which are connected to a control unit 18 via line 16 or 17. This control unit 18 is connected via a line 19 to a valve 12 which controls the application of compressed air to the cylinder 13 from a compressed air source 21.
- the shaft 10 is in the region of the bearing of the arm 7 with a longitudinal profile, e.g. a serration on which the arm 7 can be moved vertically. This profiling on the shaft piece 22 enables vertical displacement on the one hand and entrainment during the rotary movement of the shaft 10 in the horizontal direction of the telescopic arm 7 on the one hand.
- This rotary movement is generated in the example shown by a motor 28 which, via a spur gear 29 with a gear 30 in Drive connection is established, which is rotatably connected to the shaft 10.
- the motor 28 is controlled by a control unit 31, which signals from end stops 44 and 46 are transmitted to limit the horizontal pivoting movement of the arm 7. (Fig. 2).
- the cylinder 13 for the vertical adjustment of the arm 7 is articulated on a part 32 connected to the lower part of the shaft 10 in a rotationally fixed manner and on the telescopic arm 7.
- Other structural designs for pivoting and shifting the arm 7 are also possible.
- the telescopic arm 7 is formed from a first part 33, in which a sliding part 34 is slidably mounted.
- the displacement movement takes place by means of a cylinder 35, which is fastened on the first part 33 and on the displacement part 34.

- the spray gun has a mixing chamber 47 and an outlet nozzle 48 on its front part.
- the pointed pistol 8 is provided with a total of four feed lines. Via line 52, a pressure chamber within the spray gun is pressurized with compressed air from an external compressed air source 55 via a valve 56. The valve 56 can be actuated via a control unit 53.
- nozzle 48 When compressed air is supplied via valve 56, nozzle 48 opens, causing an adhesive to escape.
- Two paint containers 60 and 61 are connected to the mixing chamber 47 via the lines 58 and 59.
- Shut-off valves 63 and 64 are switched into the lines 58 and 59 between the paint containers 60 and 61 and the mixing chamber 47.
- Two further containers 68 and 69 can be connected to the mixing chamber 47 via the fourth line 66.
- the feed line of the container 68 which serves to hold an adhesive, is provided with a check valve 71, via which the supply of the adhesive into the line 66 can be interrupted.
- the supply from the container 69 which serves to hold a cleaning agent or solvent, can be shut off via a check valve 72 to the line 66.
- the containers 60, 61 and 68, 69 are pressurized via a compressed air source 75, which is connected to the compressed air source 55 via a line 76.
- a compressed air source 75 which is connected to the compressed air source 55 via a line 76.
- a sensor 78 is attached to monitor whether a coil 5 from the transport system 3 is present at the transfer point.
- This sensor 78 can be an optical sensor, for example, which scans the outer circumference 79 of the coil 5.
- the sensor 78 is connected to the control unit 53 via a line 80.
- the lower fastening part 49 of the spray gun 8 is provided with elongated holes 50, through which screws 51 of the bracket 45 protrude.
- the position thus set is fixed by nuts, not shown, which are tightened to the Screw 51 the fastening part 49 against the bracket 45.
- this vertical adjustment device automatically, for example via a displacement cylinder or displacement motor. This automatic shift could then take place during the application of adhesive to each coil in order to increase the application of adhesive in the vertical direction (see, for example, FIG. 10b).
- FIG. 5 shows a further exemplary embodiment, which essentially coincides with the embodiment according to FIG. 1.
- the application device or the spray gun 8 is not located on the transfer device 6, but rather on the conveying path of the transport device 4 after the delivery point 82.
- An enlarged side view of this application device 8 is shown in FIG. 6.
- the previously indicated rail transport system is also shown schematically.
- the transport path 4 is assigned a sensor 83 at a predetermined distance from the transfer point 82.
- This sensor 83 can also be an optical sensor that monitors for the presence of a full coil.
- the sensor 83 is connected to a control unit 25, which controls the drive 24 of the transport system 4.
- the spray gun 8 (FIG. 6) is attached to a fixed frame 87 via an elongated hole guide 85, which can be adjusted in the vertical direction by means of a cylinder 86.
- the nozzle 48 of the spray gun 8 is aligned at the level of the last turn 88 of the roving end.
- Fig. 7 shows the possibility of shielding the nozzle 48 to prevent deposits at this point.
- Deposits fiber fly, dirt particles or the like
- Is coaxial to the nozzle 48 therefore provide a nozzle 89 with an annular air outlet 90 to shield the nozzle 48.
- the nozzle 89 is continuously supplied with a low air pressure via a compressed air line 92.
- the annular air curtain can also be formed by individual outlet openings of the nozzle 89 lying next to one another and arranged in a circle. The air pressure of the nozzle 89 may only be so great that on the one hand it prevents the ingress of dirt or the like to the nozzle 48 and on the other hand does not impair the application process for the adhesive. Also, the annular air curtain must not lead to a negative change in the outer turns of the coil 5 being passed.
- FIG. 8 schematically shows a cleaning device 93 in the form of a pivotable brush 94.
- the brush 94 is fastened in a rotationally drivable manner and is set in rotation by a drive (not shown in more detail). This removes contaminants adhering to the nozzle 48.
- a suction device for the stripped impurities could also be attached.
- Fig. 9 shows schematically the cleaning process for cleaning the mixing chamber 47 of the spray gun 8 and the nozzle 48.
- This cleaning process is carried out using the solvent from the container 69 and is used in particular when a color for identifying the coil from the container 61 or 60 should be used. It is important, in order to avoid faulty color markings, that the color substance previously used is completely removed from the mixing chamber 47 or the nozzle 48 and the common pressure hose when changing the color.
- a container 95 is delivered to the nozzle 48, which the escaping solvents with the paint or adhesive to be removed.
- the solvent from the container 69 can also be used to remove blockages from the adhesive, for example after the spray gun 8 has been idle for a long time.
- 10a to 10d show various possibilities for applying adhesive to the spool 5.
- 10a shows a punctiform adhesive dot 97 which is achieved when the spray gun 8 and the coil 5 are firmly positioned relative to one another.
- either the coil 5 or the spray gun 8 or both are displaced in opposite directions vertically during the spraying process. It is conceivable to use the already existing vertical movement of the coil 5 during removal from the transport system 3 to achieve such an adhesive layer.
- the annular adhesive layer according to FIG. 10c is created by the additional turning of the coil 5 during the injection process.
- the ring-shaped application could also be applied only over a partial area of the circumference of the coil 5.
- Such a rotating device is e.g. shown and described in the embodiment of FIG. 3.
- the adhesive layer corresponding to the embodiment according to FIG. 10d is created by a vertical movement and a rotary movement of the coil or the spray gun 8 during the spraying process.
- the coils 5 of the transport system 3 are fed step by step via a control unit 26, which controls the drive of the transport system 3, to a transfer point 6.
- a control unit 26 which controls the drive of the transport system 3, to a transfer point 6.
- the drive system of the transport system 3 stops. This can e.g. can be monitored with a sensor 78.
- the arm 7 is in the position drawn with solid lines, which is also reported by the end stop 44 to the control 31 for the motor 28 and to the control 18 for the control of the valve 20.
- the valve 20 is now opened and the cylinder 13 is pressurized. As a result, the arm 7 moves into an upper position until it comes to rest against the end stop 14. The end stop 14 reports this end position to the control 18, which closes the valve 20 and thereby stops the upward movement of the arm 7. During this upward movement, the sleeve 23 is received by the receiving pin 37 and pivoted upwards so that the connection between the hanging pin 12 and the sleeve 23 of the coil 5 is released. After reaching this upper position and unlatching the coil 5, the valve 20 is switched over again, whereby the arm 7 moves into its lower position shown in FIG. 3.
- the spray gun 8 When this lower position is reached, the spray gun 8 is pressurized with compressed air via the line 52, as a result of which the valve of the nozzle 48 opens.
- the shut-off valve 63 or 64 for one of the paint containers 60 or 61 is open, as a result of which dye reaches the interior of the mixing chamber 47.
- the shut-off valve 71 of the container 68 for the adhesive is also opened, the adhesive also entering the mixing chamber 47.
- the check valve 72 for the container 69 of the Solvent is closed.
- the adhesive / colorant mixture is applied to the coil surface 79 in the area of the last turn 88 of the roving end.
- the coil 5 can be rotated via the motor 40 during the injection process, as a result of which an extensive adhesive strip is applied. (Fig. 10c).
- the drive 28 is released for executing a horizontal rotary movement of the arm 7.
- the last roving turn is deposited in relation to the longitudinal axis of the bobbin 5 always in a predefined area which can be defined by the flyer control.
- Possible height adjustments of the spray gun 8 could be carried out in accordance with the example according to FIG. 4.
- the control of the spray device can also be carried out in such a way that the spraying is carried out during the horizontal pivoting process of the arm 7. As soon as the arm 7 has reached the position shown in broken lines in FIG. 2, it comes to rest against the end stop 46. As a result, the drive 28 is stopped and the controller 38 is released to act on the valve 39. The pressure medium supply to the cylinder 35 is now released and the cylinder 35 is extended until the receiving pin 37 with the coil 5 assumes the transfer point 82.
- This displacement movement of the displacement part 34 with respect to the first part 33 of the arm 7 can be limited by end stops integrated in the cylinder 35 or by additional stops (not shown).
- the valve 20 is released again via the control 18, as a result of which the arm 7 is displaced into an upper position again via the cylinder 13.
- This vertical Adjustment engages the sleeve 34 of the coil 5 in a hanging pin 12 which is appropriately positioned on the transport system 4 and which further transports the coil 5 in the suspended position when the arm 7 is subsequently moved into a lower position.
- the hanging pin 12 of the transport system 4 can be positioned by means of sensors (not shown).
- the arm 7 After the coil 5 has been transferred to the transport system 4, the arm 7 returns to its solid position shown by reversing the motor 28, as a result of which the process for transferring the coil begins with the application of an adhesive lock and identification.
- the controller 26 of the transport system 3 is connected to the controllers 18, 31 and 38 in terms of control in order to enable a coordinated coil transfer.
- the drive 24 is informed via a sensor (not shown) that it can switch from a discontinuous transport process to a continuous transport in order to transfer the transferred spools to the ring spinning machine 2.
- the outer circumference of the coil 5 is at a short distance from the nozzle 8 of approximately 10 mm. This ensures a concentrated application of the adhesive.
- the further exemplary embodiment according to FIGS. 5 and 6 also has a transfer device with a telescopic arm 7 corresponding to the mode of operation according to the first exemplary embodiment, but the spray gun 8 is not located on the telescopic arm 7.
- the takeover or delivery process of the coils 5 corresponds to that of the first one Embodiment described.
- the attachment of a motor 40 for rotating the mounting pin can be dispensed with in this second exemplary embodiment.
- the coil 5 is shifted further from this point by one division via the drive 24 until a new hanging pin 12 is again available at the transfer point 82 for receiving a further coil 5.
- this positioning can be carried out by a sensor.
- the coil 5 transported one step further from the transfer point 82 now arrives in the region of the spray gun 8, which is fastened to a frame 87.
- the presence of a full coil at this point is monitored by an additional sensor 78.
- This sensor 78 also releases the application of compressed air to the spray gun 8 in order to apply an adhesive or paint layer. Via the cylinder 66, the spray gun 8 is displaced in the vertical direction during the spraying process, so that an adhesive layer corresponding to FIG. 10d is achieved.
- the sensor 83 which is arranged at a certain distance from the adhesive gun 8, reports that the adhesive process has been carried out for all coils. This message is sent to the controller 25 to act on the drive 24, which switches from discontinuous to continuous conveying of the coil 5 for transfer to the ring spinning machine 2.
- the mixing chamber 47 or the nozzle 48 is passed through, as already described for the exemplary embodiment according to FIG. 9 Connection of the solvent of the container 69 cleaned. Valves 71, 64 and 63 are closed during this cleaning process. After the cleaning process, the valve 72 is closed again and the valve 71 and the corresponding valve 63 or 64 are opened. The gluing process or labeling can now start again.
- FIG. 11 shows a further embodiment of an application device for the adhesive in the form of a pivotable roller 100.
- the roller 100 exerts a slight pressure on the last turn 88, so that the adhesive is applied securely and crosslinking to the adjacent turns takes place.
- An arm 101 which is pivoted about a pivot point D, supports the roller 100 so that it can rotate. The pivoting movement of the arm 101 takes place via a cylinder 102 which is articulated on the arm 101 and on a frame.
- a container 103 is arranged below the pivot point D, in which the roller 100 (as shown in dash-dot lines) can be immersed in order to again take up adhesive K with which the container 103 is filled.
- the roller is pivoted accordingly, the distance between the coil surface to the pivot point D being always selected so that the roller exerts a slight pressure when applied.
- the roller 100 is pivoted into a lower position in order to release the spool.
- FIG.12 Another embodiment is shown in Fig.12, where the application device in the form of a stamp or Swab 105 is formed.
- the stamp 105 is slidably mounted in a guide 106 and has at its front end an absorbent sponge 107 which extends into the interior of the stamp 105, which is equipped with a chamber (not shown in more detail) for receiving the adhesive.
- the sponge soaks up the adhesive and is placed with slight pressure on the last turn 88 of the coil 5, as a result of which it delivers the adhesive to these and adjacent turns and carries out crosslinking.
- the stamp is moved back into its rear position via the cylinder 108.
- the adhesive can be refilled in the chamber of the stamp 105 via an indicated line 110.
- a sensor 78 is attached to the positioning of the coils 5, which sensor faces the application device.
- the end of the pregain is stored in a specific and known area.
- a method would also be conceivable, in which a search device or a search process for locating the end of the roving before the spraying is connected upstream of the last turn 88 of the coil 5 for positioning the spray gun 8.
- a simple and functional securing of the roving end is achieved by the proposed arrangement, with no negative influences resulting from the roving securing during the subsequent spinning process.
- the roving end secured in this way can be removed relatively easily by an operator or automatically from the bobbin 5 and can be attached to the ending end.
- the roving protection is only a slight networking of adjacent turns in the roving end. The roving is not damaged as a result and is given sufficient security that prevents unwinding during transport
