Description

  The present invention relates to a working unit of an automatic traverse winder described in the premise of claim 1. That is, the present invention is rotatably supported having a storage pocket that is actuated by a drive device and is positionable at a defined angular position and that houses a storage bobbin prepared for the rewinding process. A rotary magazine and a payout position disposed under the rotary magazine, and a device for fixing one storage bobbin at the payout position in the payout position area in the payout position, and the payout being completed The present invention relates to a working unit of an automatic traverse winder in which a device capable of discharging a winding tube of a storage bobbin is disposed.

  The working part of an automatic winding machine is known in various forms and is described in detail in numerous patent applications.

  In such a working part, the storage bobbin, which is a spinning cup made with a relatively small amount of yarn material, preferably manufactured in a ring spinning machine, is rewound into a large volume twill package, in this case the rewound process. In some cases, yarn defects that may be present are cleared.

  In this connection, the automatic traverse winder in which the storage bobbin is continuously supplied to the working unit via the spinning cup and the winding tube conveying device unique to the textile machine is also an area of many working units. In addition, an automatic traverse winder having one rotary magazine specific to a working unit arranged at an operation height and accommodating a plurality of storage bobbins simultaneously is also known.

  In the automatic traverse winder disclosed in DE19539762A1, the working parts are each provided with a rotary magazine arranged at the operating height as described above for accommodating a storage bobbin. In such a working section, one so-called cup chute (Kopsrutsche) is arranged under the rotary magazine, and a chute flap that can be opened and closed is provided on the cup chute.

  The cup chute is associated with a wound tube insert mandrel that secures the storage bobbin during the rewinding process and to communicate the function. A winding tube ejector is further provided in the region of the winding tube insertion mandrel, and the winding tube ejector can then discharge the winding tube of the storage bobbin that has been fed out.

  The cup chute and the winding tube insertion mandrel are connected to a drive device which is, for example, a step motor via a lever link device and a mechanical transmission device. In other words, the cup chute and the winding tube insertion mandrel can be pivoted selectively between the cup delivery position or the cup acceptance position and the feeding position by corresponding control of the step motor. The winding tube ejector of the working unit is also connected to the step motor via a lever link device and a mechanical transmission device, and can be controlled accordingly if necessary.

  In such a known working part, the cup chute is used to move the storage bobbin previously accommodated in the rotary magazine when the cup chute is positioned in its delivery position and at the same time the chute flap is closed. A guide and centering means is formed for reliable transfer to the winding tube insertion mandrel positioned at the center. That is, if necessary, the cup chute works so that the storage bobbin released from the rotary magazine is properly positioned on the winding tube mandrel.

  Usually, after the storage bobbin formed as a spinning cup is mounted on the winding tube insertion mandrel, the cup chute and the winding tube insertion mandrel are swung to the feeding position, and in this feeding position, the cup chute is arranged in a stationary manner. In association with the dorsal part, it forms a feeding chamber for the spinning cup capable of supplying negative pressure.

  In this unwinding chamber, the spinning cup is then unwound from the top, in which case the yarn is simultaneously monitored for yarn defects as usual during the rewinding operation, and the yarn defects are optionally cleared.

  After the storage bobbin is fed out, the cup chute is swung back to the accepting position together with the associated winding tube insertion mandrel and the winding tube disposed on the winding tube insertion mandrel, and the chute chute flap is The open tube is swung open and the empty tube is lifted from the tube insertion mandrel using a tube ejector. In this case, the lifted empty tube is preferably delivered to a machine-length winding tube conveying device, and the winding tube is unloaded by the winding tube conveying device.

  Certainly, such a known working part of an automatic winding winder has proven to be reasonably good in practice, but this known working part still has some remedies that can be improved. .

  In order to properly position the storage bobbin on the winding tube insertion mandrel, in order to pivot the winding tube insertion mandrel together with the storage bobbin to the feeding position of the working part, and to position it in the feeding position, and at the end of the rewinding operation, Mechanical transmissions and lever devices are used to ensure that the spool of the storage bobbin that has been unwound is discharged again, but the structural costs required are considerably higher.

  Another disadvantage of such mechanical transmission and lever devices is the risk of injury due to such devices and the fact that such devices are very sensitive to contamination.

  Therefore, such mechanical transmissions and lever devices are usually protected for this reason, and are thus somewhat inaccessible and placed behind the cover. And with such an arrangement, there is a risk that the required cleaning interval may be postponed for a long time until it is completely neglected.

  That is, in known working parts, the cleaning intervals for the transmission and lever devices are often postponed until a failure such as a malfunction occurs during the exchange of empty tubes and spinning cups in the working part. .

DE19539762A1

  Therefore, the problem of the present invention is that the working part of the automatic traverse winder is always reliable and appropriate for the working part of the automatic winding winder, even under difficult ambient conditions, starting from the prior art described above. It is to improve so as to guarantee that proper driving is guaranteed.

  This problem is solved by a working unit having the configuration described in the characterizing portion of claim 1.

  That is, in the configuration of the present invention to solve the above-described problem, in the working section described at the beginning, the working section has a plurality of pneumatic valves, and the pneumatic valves are used for changing the angular position of the rotary magazine. It is automatically operated via a drive and is connected via air lines to a plurality of pneumatic cylinders provided in the region of the working part, in which case the first pneumatic valve is inserted into the winding tube The first pneumatic cylinder for operating the mandrel is connected to the second pneumatic valve, and the second pneumatic valve for operating the winding tube ejector supported to be pivotable is connected to the second pneumatic valve. .

  Further preferred embodiments of the invention are described in the dependent claims.

  According to the present invention, the first pneumatic valve is connected to the first pneumatic cylinder for operating the winding tube insertion mandrel, and is wound to the second pneumatic valve so as to be turnable. Is connected to a second pneumatic cylinder.

  Such a configuration has the following advantages in particular. That is, in the working part according to the invention, a machine which is sensitive to contamination by transmitting the necessary kinetic energy to devices provided in the region of the working part, for example devices such as a wound tube insert mandrel and wound tube ejector. The use of formula components can be omitted. In other words, the working part according to the present invention does not have a mechanical force transmission element located behind the cover. With such a force transmission element, the force transmission element is based on its somewhat difficult accessibility. May be insufficiently cleaned, and as a result, a failure may occur in the working unit over time.

  In a preferred embodiment, the third pneumatic valve is connected to a third pneumatic cylinder, and the third pneumatic cylinder is arranged under the rotary magazine. The pivoting supported loading chute is positioned in a first position where a new storage bobbin is prepared in the intermediate position or in a second position where the storage bobbin is transferred from the intermediate position to the winding tube ejector. . With such a loading chute arranged under the rotary magazine and supported pivotably, on the one hand, the time required for exchanging empty tubes and storage bobbins can be minimized, and on the other hand, The use of the third pneumatic cylinder as a driving device for the loading chute is a relatively simple and reliable configuration.

  According to a preferred aspect of the present invention, the winding tube insertion mandrel is supported in a tiltable manner, and the storage bobbin and the receiving position are provided by the first pneumatic cylinder capable of supplying air via the first pneumatic valve. It can be moved between the feeding positions.

  In this case, the winding tube insertion mandrel may be formed as a clamping device, for example as described in DE 102004045747A1, which has two clamping claws that can be applied to the inner wall of the winding tube at different heights. The clamping claw group which has a group and can be loaded independently of each other by means of a spring element can be easily controlled in the direction of "dissociation" by means of the first pneumatic cylinder.

  However, the winding tube insertion mandrel may also be formed as another form of clamping device, as is known, for example, on the basis of CH396718A, which comprises a stationary winding tube receiving mandrel and this winding tube receiving shaft. A tightening lever that is pivotally supported with respect to the mandrel and can be abutted against the inner wall of the winding tube.

  The clamping lever, preferably pressed by the spring element, is likewise controllable in the direction of “dissociation” by the first pneumatic cylinder. Regardless of the respective configuration of the winding tube insertion mandrel, it is possible to operate the winding tube insertion mandrel at any time via the first pneumatic cylinder. That is, the winding tube insertion mandrel can be positioned without problems when the winding tube insertion mandrel is necessary, accepts the storage bobbin supplied from the winding tube ejector, securely fixes the received winding tube bobbin, and The storage bobbin is configured and defined and supported for movement so that the yarn can be transferred from the top of the storage bobbin to a feeding position where the yarn is fed out.

  Furthermore, in a preferred aspect of claim 4, the winding tube ejector is defined so that a new storage bobbin transfer from an intermediate position located below the rotary magazine to the winding tube insertion mandrel is feasible or desired. As described above, the winding tube of the storage bobbin that has been fed out can be configured and controlled so that it can be removed from the feeding position. That is, by using the second pneumatic valve, a new storage bobbin is transferred to the winding tube insertion mandrel in the pneumatic cylinder of the winding tube ejector, or the winding tube of the storage bobbin that has been fed out is transferred. , Preferably air fed so as to be transferred to a machine-length winding tube conveying device.

  Furthermore, in a preferred embodiment as claimed in claim 5, the pneumatic valve is automatically actuated by a defined actuation of the pneumatic valve in response to a change in the angular position of the rotary magazine, which is necessary in connection with the delivery of a new storage bobbin. It is connected to a switching element arranged in the rotary magazine drive so that it can be produced. In other words, with this configuration, it is not necessary for the operator to take any action in order to introduce necessary measures in connection with the empty tube / storage bobbin replacement operation.

  According to a sixth aspect of the present invention, the switching element has a plurality of switching cams respectively corresponding to one of the plurality of operation members supported so as to be movable in the axial direction of the pneumatic valve.

  That is, when the angular position of the rotary magazine changes, the operation member of the pneumatic valve arranged in a stationary manner is first, in the respective switching cam corresponding to the switching element provided in the area of the rotary magazine drive unit, Sliding or rolling.

  When the operating member reaches the end of the respective switching cam, the operating member is moved somewhat in the axial direction, whereby the associated pneumatic valve is defined and controlled, so that, for example, a winding tube insertion mandrel, Connected devices such as a winding ejector and loading chute are operated properly.

  As defined in claims 7-10, the pneumatic valves are preferably each defined via an operating member, which is supported in the valve housing for axial movement and is spring-loaded, and an operating member. It has a switching piston which is loadable and likewise axially movable, preferably with a central air vent passage, and a sealing element corresponding to the working piston.

  For example, as in claim 8, a spring element is arranged between the switching piston and the sealing element, and the spring element presses the sealing element and the switching piston respectively toward the end position.

  That is, in practice, the sealing element is always positioned at a predetermined end position by the spring element, whereas the switching piston is moved from its end position against the force of the spring element when the operating member enters. .

  According to the ninth aspect of the present invention, when the pneumatic valve is not switched, that is, when the operating member is not loaded or pressed, the working piston loaded with spring has the sealing surface on the upper side of the working piston sealed. Positioned to contact the element.

  In this switched state, the valve outlet connected to the pneumatic cylinder via the associated air line and the valve outlet connected to the positive pressure source via another appropriate air line are mutually empty. Separated by pressure. Furthermore, the switching piston is positioned so that the valve outlet is connected pneumatically and consistently to the switching piston air vent passage by a spring element arranged between the switching piston and the sealing element. That is, the positive pressure generated in the connected state of the pneumatic cylinder can escape through the air vent passage, and at this time, the region of the operating member of the pneumatic valve can be cleaned.

  According to a tenth aspect of the present invention, when the operating member is loaded or pressed, and when the pneumatic valve is switched, the working piston and the switching piston are provided with a valve inlet and a valve outlet of the pneumatic valve. Are positioned so as to communicate pneumatically. That is, in this switching position, the pneumatic cylinder connected to the pneumatic valve via the valve outlet is connected to a positive pressure source connected to the pneumatic valve via the valve inlet.

  The pneumatic cylinder can be supplied with compressed air from a positive pressure source, correspondingly adapted to the needs.

  FIG. 6 shows an unswitched pneumatic valve, i.e. the operating member 34 of this pneumatic valve is not shifted in the axial direction. On the other hand, FIG. 7 shows the switched pneumatic valves 41, 42, 43, that is, the operating members 34 of the pneumatic valves 41, 42, 43 are shifted in the axial direction. The piston 35 is loaded, that is, pressed in a frictional force coupling type (kraftschluessig).

  As can be seen from the drawings, each of the pneumatic valves 41, 42, 43 has a valve housing 15, which is preferably made of plastic and has a centrally stepped receptacle 49. ing. The stepped accommodating portion 49 has a guide step portion 50, a compressed air inflow region 56, and a compressed air outflow region 57, and is closed by a valve housing cover 60 upward.

  The working piston 16 is guided in the guide step portion 50 disposed in the bottom region of the valve housing 15 of the stepped accommodating portion 49, and the working piston 16 is provided with a ring groove 51, A seal element 52 is disposed in the ring groove 51.

  The working piston 16 is pressed against the sealing element 37 arranged in the air outflow region 57 by the spring element 53 in the mounted state. In this case, the spring element 53 is supported by a shim plate 55, and the preload or preload of the spring element 53 can be adjusted by the shim plate 55.

  The working piston 16, preferably also made of plastic, is provided with a contact element 54 on its upper side, which contact element 54 is made of a hard material, for example steel, on top of the contact element 54. The side surface is in contact with the sealing element 37 by the action of the spring element 53.

  As can be further understood from FIGS. 6 and 7, the circular guide step portion 50 is connected to a compressed air inflow region 56 having a diameter that is significantly larger than that of the guide step portion 50. 56 is followed by a compressed air outlet region 57 having a somewhat larger diameter.

  The compressed air inflow region 56 includes a valve inlet 40, that is, a valve opening 58 is arranged in the compressed air inflow region 56, and a connection pipe piece 59 is provided in the valve opening 58. Is connected to an air line 47, and this air line 47 is further connected to a positive pressure source 48. The compressed air outflow region 57 connected to the compressed air inflow region 56 has the sealing element 37 as described above, and the spring element 38 is supported on the sealing element 37, and the spring element 38 is switched. The piston 35 is pressed toward its end position.

  That is, the spring-loaded switching piston 35 is in contact with the valve housing cover 60 when the pneumatic valves 41, 42, 43 are not switched as shown in FIG. It is connected to the valve housing 15 by suitable connecting means such as bolts 61 and sealed by a ring packing 62.

  In particular, during the pneumatic valve switching operation, the mounting portion 66, which cooperates with, for example, a steel spherical operating member 34, is likewise preferably made from a wear-resistant material such as steel.

  As can be seen in particular in FIG. 6, when the pneumatic valve is not switched, that is, when the operating member 34 is not shifted in the axial direction, the contact element 54 of the working piston 16 is in contact with the sealing element 37, Thus, the compressed air inflow region 56 of the pneumatic valve is pneumatically blocked from the compressed air outflow region 57.

  Furthermore, in this switching state of the pneumatic valve, the switching piston 35 is pressed by the spring element 38 and is located at the end position, in which the seal ring 65 of the switching piston 35 is in contact with the contact element 54 of the working piston 16.

  In this switching state of the pneumatic valves 41, 42, 43, the switching piston 35 is in contact with the contact element 54 of the working piston 16 by its seal ring 65, and at this time, positive pressure in the compressed air inflow region 56 is reached. On the other hand, not only is the air vent passage 36 of the switching piston 35 sealed, but the working piston 16 is moved somewhat downward.

  During this shift of the working piston 16, the contact element 54 of the working piston 16 is separated from the sealing element 37, so that the valve inlet 40 and the valve outlet 39 are in pneumatic communication and are thereby connected to the valve outlet 39. Compressed air is supplied to the pneumatic cylinders 11, 12, and 17 defined through a positive pressure source 48 connected to the valve inlet 40.
