Definitions

  • This invention relates to a traverse device for a winding machine for winding endless synthetic filament yarns.
  • Traversing devices are used in winding machines to move a thread to be wound back and forth in the axial direction of the spool during the spool build-up.
  • the device is usually attached to the machine frame as a removable unit.
  • the unit contains a carrier (usually a housing), the traversing device itself and drive-transmitting elements for transmitting driving forces from a motor provided in the machine to the traversing device.
  • the traverse device which is still conventional today, has a grooved roller and a thread guide which engages in the groove of the roller via a so-called ship. Examples of this construction are in the U.S. patents 3664596 and 3934831 can be found. Alternative designs in the form of so-called wing traversing, belt traversing and others have recently been proposed, see for example the German DOS 3516475 and DAS 1535091.
  • the present invention can be used with all of these types of traversing.
  • the bobbins or packages are built on a rotatable, overhung spool.
  • the traversing device extends parallel to the coil mandrel and over at least the length of the coil mandrel on which coils are to be built up in use.
  • the carrier of the device is therefore normally attached to the machine frame at one end.
  • Such an arrangement is e.g. described and shown in British Patent 1304609, the various elements being indicated only schematically. In the system described in this British PS, many filament yarns are wound into a bobbin on individual bobbins. Each coil mandrel and therefore its corresponding traversing device is relatively short.
  • the traversing devices must also be constructed correspondingly longer, the number of individual traversing devices in each traversing device corresponding to the number of threads to be wound on the mandrel.
  • a traversing device like the already usual traversing devices, contains a carrier section, at least one traversing device carried by the carrier in a predetermined arrangement, and drive elements for the traversing device.
  • the carrier preferably has a length which corresponds at least to the length of the winding area of the winding machine.
  • the drive for the traversing will have to be transferred from a drive source provided in the machine to the traversing device.
  • the device with an element ei ner automatically attachable coupling.
  • the new traversing device is preferably also provided with a manually operable locking device in order to hold the device in the said operating position. If the machine is provided with a full casing, the arrangement can be made such that the traversing device can only be removed from the machine after the machine door has been opened.
  • Control connections can be arranged so that the machine cannot be put into operation until a traversing device has been brought into said operating position. Accordingly, it can be arranged that the traversing device cannot be removed from the machine until the machine has reached a predetermined state (standstill).
  • FIG. 1 is essentially a copy of Figure 10 of our European Patent Application No. 86108531.4. The figure has only been changed with respect to the traverse 22, as will be described below. For now, however, the other parts of the machine shown will be described to show the "environment" of the inventive innovations.
  • the use of the reference symbols in FIG. 1 corresponds to the use in FIG. 10 of the European application.
  • the machine shown comprises a housing, which cannot be seen in the figure, since it is directly behind the parts shown.
  • the machine has a "working zone" in front of the housing, where the supplied threads are formed into bobbins (packages).
  • a contact roller 18 drive roller or tachometer roller
  • two spools 24, 26 protrude from the housing into the working zone.
  • the housing itself contains support and drive components for these parts 18, 24, 26.
  • the working zone of the machine is given a "full casing", of which a base plate in FIG. 1 10, a cover 12, a side wall 14 and a front wall 20 are indicated schematically.
  • the front wall 20 consists of a fixed part 30 and a door unit 32. The latter is connected by fishing (not shown) on its left edge to the left side wall (not shown) of the casing.
  • the unit can be rotated forward about a vertical swivel axis to ensure free access to the work zone. However, it is normally held in the closed position in the front wall 20 by a lock 104.
  • the door unit 32 comprises a frame 38, a lower double door 40 and an upper double door 42. These double doors can be moved vertically in the frame 38, as is described in detail in the European patent application. If the lower double door 40 is moved upwards, thread packages can be removed from the lower spool mandrel 26 and replaced by empty sleeves. Similarly, thread packages from the upper mandrel 24 can be replaced by empty sleeves when the upper double door 42 has been brought down.
  • the reference numerals 44 and 46 indicate respective glass panes, which permit the visual monitoring of the condition of the working zone. With the reference numeral 28, the thread run through a slot 34 in the cover 12 is indicated.
  • the threads to be wound run out of the machine again through a further slot 33 in the cover 12 until they are taken over by one of the bobbin mandrels 24, 26.
  • a cover plate 35 for this second slot 33 is then pivoted about an axis of rotation 37 into a vertical position (indicated by dash-dotted lines) in order to open the slot 33.
  • the slot 33 is covered by the plate 35 (solid lines).
  • the reference numerals 162, 164, 166, 168, 170 indicate different channels which protrude from the housing, not shown, into the working zone. Various lines are led through the channel 162 to the door unit 32.
  • the channels 164, 166 serve to supply the working zone with cooling air, which flows out of the working zone again via the channels 168, 170. Individual winding machines of this type can therefore be individually air-conditioned.
  • the aforementioned thread path 28 extends from the slot 34 around the contact roller 18 to a winding area which is described in European Patent 73930 and British Patent Application 8531151 but is not shown in Fig. 1 since it is not relevant to this invention.
  • 1 is a front view, only one thread path 28 can be seen, although a plurality of threads can be processed at predetermined intervals along the roller 18 at the same time. For the sake of simplicity, only one thread is mentioned in the further description. What is said for this thread applies to all threads processed at the same time.
  • Fig. 1 like Fig. 10 of the European patent application, indicates a conventional traversing with a grooved roller 23 and a thread guide 21 moved by the grooved roller.
  • This traversing extends from the housing, not shown, parallel to the roller 18 into the working zone Machine, and its front ends is in part 30 of the front wall 20 under the control panel 36.
  • the arrangement of this traversing in the whole machine is a matter of this invention and will now be explained in more detail with reference to the other figures.
  • the entire traversing device is indicated in FIG. 2 with the reference number 50.
  • This device comprises a support 52, which is formed as a cast part and extends over the entire length of the working zone of the machine.
  • a drive shaft 27 for the grooved roller 23 is mounted for rotation about its own longitudinal axis 25 (FIG. 4) in a rear end section 54 and a front end section 56 (FIG. 3) of the carrier 52.
  • the carrier 52 is provided on its underside with an outwardly opening groove 58 (FIGS. 2 and 4).
  • the carrier 52 offers a surface 60 (FIG. 2) to the outside on both sides of this groove.
  • the carrier 52 is formed as a housing for the grooved roller, but has an opening 53 in its longitudinal side directed towards the machine working zone. This opening is largely covered by two strips 55, 57, but leaving a linear guideway for the thread guide 21.
  • the reference number 59 indicates a pin which is installed in the upper bar 55 and which pushes the thread into the thread guide 21 during a bobbin change.
  • a unit 62 sits on the top of the carrier 52 and is used during the threading phase.
  • This unit comprises a so-called feed plate 64 which is rotatably supported about an axis 68 by a lever 66.
  • the lever 66 is shown in an upper position which it assumes during normal operation and thereby holds the plate 64 in a retracted position.
  • the lever 66 can be pivoted downward (counterclockwise in FIG. 2) about the axis 68 in order to bring the sheet metal 64 into a covering position indicated by dash-dotted lines, which prevents the thread from penetrating into the thread guide 21.
  • the feed plate 64 is moved back into its retracted position in order to release the thread 21 for normal traversing.
  • the unit 62 further comprises a lift-off plate 70.
  • This plate is also rotatably mounted (details not shown) so that it can be brought from an retracted position (shown in FIG. 2) into an operating position by rotating it clockwise.
  • the take-off plate is moved into this operating position during the change phase (i.e. while the thread is being transferred from one mandrel to the other) or when the thread is being drawn in, in order to push the thread into an opposite auxiliary thread guide (not shown).
  • This function has been generally described in our U.S. Patent No. 3,920,193, so it is not discussed here.
  • the rear end portion 54 of the carrier 52 automatically carries plug-in connections 72, 74, whereby the unit 62 can be supplied with air pressure.
  • the rotary shaft 27 projects at the rear end of the traversing device 50 beyond its mounting in the end section 54 and carries an internally toothed coupling element 29 at its rear end Elements 29, 72, 74 with corresponding connecting elements on the housing of the machine, not shown, will be described in more detail below.
  • An extension 72 (FIG. 3) is attached to the front end section 56 of the carrier 52.
  • This extension carries a handle 74 and a lock, which is generally indicated by reference numeral 76.
  • the lock comprises a lever 78 which is rotatably supported by an axis of rotation 80 in the extension 72 between its ends.
  • the lever 78 At its front end, which protrudes from the extension 72, the lever 78 is provided with a button 82. Its rear end projects into a transverse slot 84 in a pin 86.
  • This pin is guided by a suitable guide (not shown) for movements perpendicular to the length of the traversing device 50, namely between an operating position (shown in FIG.
  • the machine (FIG. 1) is provided with a beam 88 which extends on the right side wall 14 between the housing and the part 30 of the front wall 20.
  • the beam is stiff in its longitudinal direction and can advantageously be used as an element of the machine frame be seen.
  • an opening 90 is left in the front wall 20, through which the traversing device 50 can be inserted into the machine.
  • the beam 88 has a wedge 92 which extends over the entire length of the beam 88.
  • the bar 88 is provided with a surface 94, which, through cooperation with the surface 60 of the carrier, serves as a support surface for the traversing device 50.
  • the traverse device 50 must be inserted into the work zone from a position on the front of the machine, and this can only be done when the door assembly 32 is pivoted to its open position (not shown).
  • the rear end portion (FIG. 4) of the device is then placed on the front end of the beam 88, the wedge 92 of the beam protruding into the groove 58 of the carrier 52.
  • the device 50 is then pushed in its own longitudinal direction against the housing of the machine, the surface 60 resting on the underside of the carrier 52 on the surface 94 on the top of the beam 88.
  • the wedge 92 and the groove 58 form a sliding guide, which ensures the correct setting of the device 50 in the direction radial to the roller 18 during this displacement.
  • the surface 94 and the wedge 92 form a slideway for the traversing device during its introduction.
  • the displacement of the device 50 continues until the end face 96 (FIG. 4) lies against the rear end of the carrier 52 on the front wall of the housing, not shown.
  • the coupling element snaps into place 29 in engagement with a corresponding coupling element (not shown) on a drive shaft of a motor which is attached to the rear of the front wall of the housing (not shown).
  • the two coupling parts together form an automatically joinable coupling, as a result of which drive forces can be transmitted from the motor to the rotary shaft 27 of the traversing device.
  • Suitable couplings are the BO-Wex types from clutch technology GmbH in Rheine, Germany.
  • the connecting elements 72, 74 insert into corresponding connecting elements on the front wall of the housing, so that compressed air from a source (not shown) provided in the housing to the unit 62 (FIG. 2) can be fed.
  • pin 86 (FIG. 3) abuts the front of portion 30 and is pressed down against the bias of the torsion spring, not shown, so that it does not prevent insertion.
  • the outer end of the pin 86 is received in an opening in a member 98 (FIGS. 1 and 3) which is fixedly mounted on the machine frame. While pin 86 remains in connection with element 98, the traversing device 50 cannot be moved along its slideway.
  • the door assembly 32 is pivoted back into its closed position.
  • the edge portion of the frame 38 on the (in FIG. 1) right side of the unit 32 overlaps the left edge portion of the extension 72 (Fig. 3).
  • This overlap is also indicated schematically in FIG. 2 by the lines 100, which indicate the position of the edge of the door relative to the support 52.
  • the traversing device 50 cannot be removed from the machine, regardless of whether the button 82 is actuated to unlock the device 76 or not.
  • the door assembly 32 can only be rotated from its closed position when the machine is in a predetermined, safe state. While the machine remains operational, the device 50 must remain in its operating position.
  • Element 98 (FIG. 1) can also be provided with a sensor (not shown) which responds to the locking setting of pin 86.
  • the sensor When the device 76 is unlocked by actuating the button 32, the sensor provides a signal which prevents the normal operation of the machine. The machine cannot therefore be started up without a correctly inserted traversing device 50.
  • the surface 94 on the beam 88 serves as a support surface for the carrier 52, which therefore no longer has to be carried exposed from one end.
  • the surface 59 directed towards the roller 18 (FIG. 2) in the groove 59 serves as a stop surface which lies against a corresponding surface on the wedge (FIG. 1) and the position of the carrier 52 in the radial direction in relation to the roller 18 (perpendicular to the thread path) defined - and over the entire length of the carrier and the roller.
  • the end face 96 (FIG. 4) also serves as a stop surface which lies against the machine housing and thereby defines the position of the fully inserted device 50 in the longitudinal direction.
  • a suitable clamping device for this purpose comprises a piston-and-cylinder unit 67 (indicated by dashed lines, FIG. 2) which can be actuated from the outside and which is fastened to the machine frame 69. After the device 50 is brought into its operating position, the unit 67 can be supplied with air in order to push the piston rod 65 downwards. It strikes a base 63, which is attached to the top of the housing 52. A plurality of such tensioning means can be distributed along the traversing device 50.
  • the invention is in no way limited to the embodiment shown. It is advantageous if a guide is provided to guide the traversing device during the introduction and means are provided to define the position of the fully inserted traversing device with respect to the thread path 28 or the roller 18. In the embodiment shown, these functions are both performed at least in part by the wedge 92. However, these functions can be fulfilled by separate parts, whereby the chan yaw device should be directed to the predetermined position.
  • a support surface that carries the device into its operating position is also an advantage.
  • this surface 94 is arranged straight on the guide wedge 92, but this is not absolutely necessary.
  • the support surface also does not have to be arranged below the device.
  • the facility could e.g. hang from a rail or be carried by a rail attached to the side wall 14.
  • the invention is not restricted to the use of traversing devices with grooved rollers. Other types of traversing have been mentioned in the introduction to this patent, and still other types are useful with this invention. Where the traversing device itself does not contain a drive source, which will normally be the case for reasons of space, the device can be provided with an automatically assembled coupling, the invention not being limited to the coupling shown. A magnetic clutch could be used.
  • the word "automatic” in this context does not mean that the cooperation between the coupling parts is only through the Introductory movements are brought about. A separate actuation for engaging the coupling parts can also be provided, the actuating element being provided at the front end of the device.
  • the invention is also not restricted to use in the machine shown. It can advantageously be used in a machine with only a single mandrel, e.g. in a system according to the aforementioned British Patent No. 1304609. It obviously has its greatest advantages where the traversing should be introduced into the machine from the front of the working zone because the long sides of the working zone are not accessible at all or only with difficulty.
  • An overlap of the front door with the traversing device is of course not essential for the invention. Where the device should not be removed from the machine before unlocking the front door, a separate lock can be provided for the device, but which is operated simultaneously with the lock 104 (FIG. 1) for the front door.
  • the guiding and supporting function for the traversing device can be carried out by a single element attached to the machine frame, e.g. a guide rod on the machine can work with a pipe on the device.
  • the traversing device can also comprise other elements, for example a wheel 105 (dash-dotted lines, FIG. 4), which rotates with the shaft 27 and, in operation, cooperates with a sensor 103 mounted in the machine in order to generate a signal which is dependent on the rotational speed or angular position of the shaft 27.
