Description

  The present invention is a yarn splicing device comprising a splicing prism and a control member that can be individually driven by a motor, wherein the splicing prism has a splicing passage that can be loaded by aerodynamic force, and the control member A thread clamping and cutting device for fixing or tightening and trimming the thread ends to be joined together, and a thread for moving the prepared thread ends into the splicing passage and positioning in the splicing passage The present invention relates to a type in which a transfer device is connected or connected. Yarn splicing devices have been well known in the textile industry, particularly in connection with automatic winders for traverse winding packages.

  Yarn splicing devices which are actually used of this type are described in German Offenlegungsschrift 4240728A1 and in the handbook "Autoconer 388" of Schlafhorst Winding Systems.

  Using a yarn splicing device, both ends of the yarn are intertwined and joined so that no knots are formed, and the joint has almost the same strength as the yarn, and ideally has an appearance almost similar to that of the yarn. It is like that. That is, when yarn breakage occurs at one of the winding points or winding devices of the automatic winder, or when the defective part of the yarn is removed, both ends of the cut yarn are first special It is pulled back to the area of the splicing device by a simple aerodynamic device. In this case, the suction nozzle pulls back the so-called upper thread from the winding package, and inserts the upper thread into the splicing passage of the splicing head of the splicing device after removing the defective yarn as necessary. In this case, the yarn is further passed through the yarn clamping device (yarn clamping device) disposed above the splicing passage and the yarn cutting device disposed below the splicing passage by the suction nozzle. Similarly, a so-called lower thread from a cup or pipe thread positioned at the winding position is also used in the splicing passage and below the splicing passage by using a gripping pipe piece that can be loaded with negative pressure. It passes through the thread cutting device arranged in the clamping device and above the splicing passage. The yarn end is then cut down by a yarn cutting device and sucked into a so-called holding and untwisting tube piece where it is prepared for a subsequent splicing process. In other words, the yarn end is first untwisted in the holding and untwisting tube piece, and then drawn into the splicing passage by the yarn transferring device, that is, transferred and overlapped in the splicing passage in opposite directions. And finally entangled with each other by aerodynamic force.

  In the above-described known yarn splicing device, the driving of various functional members (actuating members or operating parts) of the yarn splicing device, in particular, the driving of the yarn clamping and cutting device, the splicing passage cover, and the yarn transferring device is usually one. This is done via a plate cam drive. That is, the cam plate set is supported in the splicer / drive casing, and the cam plate set is connected to a drive unit unique to the winding portion via a meshing joint. Each cam plate is connected to each functional member of the yarn splicing device via a lever rod (lever link).

  Furthermore, German Patent Application Publication No. 19610818A1 and German Patent Application Publication No. 19921855A1 also disclose a splicing device, which is individually driven by a motor. ing. The known splicing device includes a grooved drum outside the splicer / drive casing, and the grooved drum has variously formed groove tracks and is driven by a reversible step motor. It has become. A control protrusion is guided in each groove track, and the control protrusion operates a functional member (functional element) of the yarn splicing device, for example, a splicer cover and a yarn cutting and yarn clamping device via a link device. Yes. Another groove track of the grooved drum is provided with track sections separated from one another for advancement and retraction in a portion of the periphery of the drum. One valve is controlled through this complicated groove track, and the valve supplies air into the preparation pipe piece. In addition, the grooved drum has a groove track for the yarn transfer device. The groove track extends partly in a stepped manner so as to cooperate with a special lever link for a defined adjustment of the swiveling distance of the yarn transfer device. That is, in order to adjust the turning movement distance of the yarn transfer device, the step motor rotates in a forward direction by a predetermined number of steps, and in this case, the grooved drum is rotated to a predetermined angular position, and the yarn is rotated at the angular position. The roller pin provided on the operation rod for the transfer device is made to coincide with a predetermined step portion of the groove track.

  The known yarn splicing device described above is extremely complex in structure and, as a matter of course, is complicated and expensive to manufacture due to the complicated grooved drum.

  The object of the present invention is to improve a yarn splicing device of the type mentioned at the outset, to enable variable adjustment or control of the swivel movement distance of the yarn transfer device by means of the yarn splicing device, and to reduce the production costs of known yarns. The cost is much less than the manufacturing cost of the splicing device.

  In order to solve the above-described problems, in the configuration of the present invention, the control member is composed of a control segment that is pivotably supported, and the control segment includes an external tooth row (arc tooth row or arc tooth portion). The external tooth row is engaged with a drive pinion of the drive unit that can be defined and controlled. The control segment is also referred to as a sector gear member, a sector gear member, or a segment gear member. As an advantage of such a configuration according to the present invention, the driving moment of the driving portion at each winding position is directly transmitted to the functional member of the yarn splicing device with almost no play. The movement process of the functional element of the yarn splicing device can be interrupted at each position exactly as needed, for example for a predetermined period of time for another work process, and then carried out again accurately, for this reason This is because the configuration based on the invention operates almost without play. As a further advantage, the splicing device according to the invention is relatively simple in its drive construction and can therefore be implemented economically.

  According to an advantageous embodiment as claimed in claim 2, at least a yarn clamping and cutting device and a yarn transfer device are connected (coupled) to the control segment via an operating member. Based on such a configuration, when manufacturing the yarn splicing device according to the present invention, it is possible to use a plurality of constituent members (components) that have already been promoted in the conventional yarn splicing device.

  According to an advantageous embodiment, the control segment is connected directly to the thread transfer device via a control rod (control link) and is non-rotatable relative to one lever via a pivot which is also used as a bearing shaft. The lever is connected (coupled or coupled), and the lever operates a yarn clamping / cutting device (yarn clamping / cutting device) via a coupling strip (coupling link or connection link). Based on such a configuration, the number of force transmission members or force transmission links connected between the drive motor and the functional member is reduced, which is not only for economical production but also for play in the force transmission path. It also helps to reduce.

  The advantages also apply to the embodiment as claimed in claim 4. In this embodiment, one lever is connected or connected to the control segment via one connecting means (a connecting part or a fixed connecting part), and the yarn clamping and cutting device is operated via the lever. Further, another pivot attachment means (connecting portion or coupling portion) is arranged on the control segment at a predetermined radial distance from the support shaft of the control segment, and the other pivot attachment means A thread transfer device is pivotally connected. A predetermined radial distance between the control segment bearing shaft and the other pivoting means defines a reference position for the operation of the thread transfer device, which is the proper positioning of the control segment. Based on the stepless adjustment.

  According to an embodiment of the present invention, in addition to the yarn clamping and cutting device and the yarn transferring device, the yarn splicing device is a cover that is provided to close the splicing passage during the yarn winding process and is pivotally supported. A member is provided. The cover member is also controlled by the control segment.

  According to an advantageous embodiment as claimed in claims 6 and 7, the control segment is also connected to the lever device via a connection pin (connection pin or connection bolt), which lever device is on the same bearing shaft as the control segment. It is supported so that it can turn. The lever device itself has the same structure as that of the known art and comprises a first lever, which is fixed directly to the control segment and via a connecting strip (connecting link or connecting link). The lever device includes a second lever that is pivotally supported on the same bearing shaft as the control segment, and the second lever is connected to (coupled to) the yarn clamping and cutting device. 2 is supported by a spring member disposed (connected) between the two levers and the first lever, and is entrained by the spring member, and a short strip (rod or The cover member is connected via a link) (pivot or hinged). With this configuration, the thread clamping and cutting device and the cover member can be simultaneously operated via the lever device during the turning motion of the control segment. In this case, the spring member (spring element) is spliced by the cover member. It prevents the cover member or the splicing prism from being damaged when it abuts on the prism, i.e., covers the splicing prism, and does not prevent the control segment from continuing to swivel. That is, the relative rotation between the control segment or the first lever and the second lever is allowed.

  According to the embodiments of claims 8 and 9, the yarn transfer device is also directly connected to the control segment via a predetermined operating rod (link). For this purpose, that is, in order to connect (link) the yarn transfer device and the control segment, the control segment is provided with a ball joint connection (ball joint connection) around the control segment. By properly controlling, i.e. defining and controlling, the swivel movement of the control segment, the working distance of the yarn transfer device is defined, i.e. adjusted to a predetermined value, and given yarn characteristics as required Can be adapted to values or yarn parameters. In other words, by shortening or lengthening the swivel movement distance of the control segment, the working stroke distance of the yarn transfer device can be changed easily, and thus the overlapping length of both yarn ends to be positioned in the splicing path. (Overlap length) can be defined and adjusted.

  In the tenth aspect of the present invention, the configuration of the yarn splicing device according to an embodiment different from the yarn splicing device according to the embodiment of the present invention shown in FIGS. 1 to 6 is described. Is supported by a separate bearing shaft and loaded or driven by an individual (unique) drive unit, and a control section member (swivel transmission member or The control lever member is disposed on the same bearing shaft as the lever device and is non-rotatably coupled to the lever device, that is, coupled to the lever device. The lever device is rotated (turned) together, and is also connected to a yarn transfer device via a rod (link). The configuration of a yarn splicing device according to still another embodiment is described in claim 11, in which the control segment is a component of a y-shaped lever member that is pivotally supported on a support shaft of the lever device, for example ( The lever portion of the y-shaped lever member, which is opposed to the control segment, is formed as a yarn transfer device or a component of the yarn transfer device. The configurations of the tenth and eleventh aspects also reduce the manufacturing cost and improve the yarn splicing device as compared with the conventionally known yarn splicing device.

The cup and winding tube transfer device 3 is formed by a cup supply section 4, a stock section 5 that can be driven in reverse, a transverse transfer section 6 that extends to the rewinding section 2, and a winding return section 7. The sleeve or the empty tube is placed on a conveying tray 8 arranged on the cup and the winding tube conveying device 3 and is sent in a vertically standing state. Each of the supplied cups 9 is rewound onto the traverse package 15 at the feeding position AS in the region of the lateral conveyance area 6 extending in the transverse direction with respect to the machine longitudinal direction under the respective rewinding points 2. Each work location (rewinding device) is where various devices (functional components or actuating devices) are used to ensure normal operation of the work location, as is known per se. In the embodiment, the various devices are a computer 29 for a rewinding device, a suction nozzle 12 that can be swung around a turning shaft 16 and can be loaded with negative pressure, and a thread clamp pipe that can be swung around a turning shaft 13 and can be loaded with negative pressure. 11 and a pneumatic splicing device (splicing device) 10.

  The aerodynamic yarn splicing device 10 is fixed to a rewinding device casing 33 via a central casing 31 of the yarn splicing device at a position slightly retracted from the normal yarn path as shown in FIG. As shown in detail in FIG. 2 to FIG. 6 or FIG. 7, the yarn splicing device 10 includes an upper and lower yarn clamp / cutting device 23, a swivelable yarn, in addition to the splicing prisms 32. A transfer device 26 and a cover member 25 that is pivotably supported are provided. The splicing prism body 32 has a splicing passage that can be loaded by aerodynamic force, and is attached to a distribution box or distribution device 46. The distribution device also receives a holding and untwisted tube piece (not shown).

  The traverse package 15 is rotatably held by the package frame 28 of the winding device 24 and rests on the grooved drum 14 on the surface, so that the grooved drum causes the traverse package 15 to exert a frictional force. In other words, the yarn wound around the winding package 15 is accurately traversed by rotating the winding package with frictional force.

  FIG. 2 shows one embodiment of a splicing device 10 according to the present invention. An individual electric motor type drive unit, preferably a step motor 22 is arranged in a central casing (accommodating casing) 31 of the yarn splicing device, and the individual drive unit, that is, the drive pinion 20 of the step motor is , Meshing with the external teeth 19 of the control segment 18.

  The control segment 18 is limitedly supported on the support shaft 17, that is, supported so as to be able to turn within a predetermined range, and is connected or connected to the lever device 35 via the connecting means 30. It is arranged on the bearing shaft 17. In this case, the lever device 35 includes a first lever 38, a coupling strip 47 for operating the yarn clamping and cutting device 23, and a second lever 39, and the coupling strip (coupling link) 47.

A spring member 37 is connected between both levers 38, 39, which receives a force from the lever 38 during the pivoting movement of the control segment 18 and applies the force to the lever 39 to entrain the lever 39. In other words, it is designed to turn. In this case, the spring member 37 may cause damage to the splicing device, particularly the splicing prism, based on the fact that the cover member 25 is mounted on the splicing prism 32 at an early stage by the turning motion of the control segment 18. In other respects, coupled with the appropriate configuration of the yarn clamping and cutting device, the control segment 18 is capable of a large swivel travel distance. The control segment 18 has a second pivoting means (connecting means) in the region of its perimeter 40, in the preferred embodiment shown, a ball joint pivot 34. A control rod 44 of the yarn transfer device 26 is connected to or connected to the ball joint pivoting portion (ball joint connecting portion) 34 (see also FIG. 6).

  FIG. 7 shows another embodiment of the splicing device 10 according to the present invention. Within the central casing 31 of the splicing device 10, the control segment 18 is preferably supported behind the cover 49 so that it can pivot within a predetermined range. The control segment 18, which can pivot about the bearing shaft 27, comprises an external tooth row 19, which is preferably meshed with a drive pinion 20 of the drive part, which is preferably formed as a step motor 22. Yes. Further, the control segment 18 has a connection flange 45, which includes a ball joint pivot portion 51. The ball joint pivot portion 51 includes an operation rod 41 and another ball joint pivot point. The control piece member 42 is pivotally supported on the support shaft 17 via a portion 53, and the control piece member 42 is connected to a lever device via a connection pin (connection pin or connection bolt) 52. 35 or connected. The lever device 35 corresponds to the lever device described with reference to FIGS. The control section member 42 includes a ball joint pivot portion 54 in addition to the ball joint pivot portion 53 for connecting or coupling the operation rod 41, and the ball joint pivot portion 54 includes the ball joint pivot portion 54. The yarn transfer device 26 is operated via a rod (link) 43 connected to the landing portion.

  FIG. 8 shows a further embodiment of the yarn splicing device according to the invention. The control segment 18 is also supported in the central casing 31 of the yarn splicing device 10 so as to be rotatable within a predetermined range. The control segment 18 also includes an external tooth row 19, and the external tooth row. Is advantageously in mesh with a drive pinion 20 of the drive, which is formed as a step motor 22. In this case, the control segment 18 is a component of a y-shaped lever member 59 that is pivotally supported on the bearing shaft 55. The lever portion of the lever member 56 facing the control segment 18 is formed as a yarn transfer device 26. That is, the control segment 18 and the yarn transfer device 26 form a common component that is pivotally supported on the bearing shaft 55.

  The lever member 56 is connected to the yarn clamping and cutting device 23 via a connecting means or connecting means 57 and an operation member (operation link) 47. A cover member 25 is also pivotably supported on the support shaft 55, and the cover member 25 closes the splicing passage in the splicing prism body 32 during the winding process. In this case, the cover member 25 is connected to the lever member 56 via the spring member 37.

  Next, the function of the embodiment shown in FIGS. 1 to 6 of the yarn splicing device according to the present invention will be described. When the yarn breakage occurs at the rewinding portion 2 or the defective portion of the yarn is removed, the suction nozzle 12 pulls back the upper yarn from the traverse package 15 and uses the guide thin plate 50 to cut and cut the upper yarn with the yarn. The thread clamping device on the upper side of the device 23, the splicing passage of the splicing prism body 32, and the thread cutting device on the lower side of the yarn clamping and cutting device 23 are passed through. At the same time or almost simultaneously, the lower thread of the cup is also conveyed upward by the thread gripping pipe 11, and the lower thread clamp device 23 using the thread guide thin plate 50, the splicing path of the splicing prism, and It is passed through the yarn cutting device on the upper side of the yarn clamping and cutting device 23.

  Subsequently, the yarn splicing device 10 is controlled via the rewinding device computer 29. That is, the stepping motor 22 starts operating the control segment 18 and turns it in the direction of arrow R as shown in FIG. 2, so that the control segment is covered by the cover member 25, the yarn clamping and cutting device 23 and the yarn transfer. The device 26 is operated. That is, after a short time has elapsed, the cover member 25 is first mounted on the splicing prism body 32 and covers the splicing passage. While the control segment 18 continues to turn, the yarn clamp and cutting device 23 is operated via the coupling strip 47 at the same time or immediately after, and the yarn clamp and cutting device 23 tightens, that is, clamps and cuts each yarn end. Subsequently, the control segment 18 is stopped for a short time, and the holding and untwisting tube pieces (not shown) arranged in the distribution device 46 of the splicing prism 32 are loaded with compressed air, whereby each yarn end is held and held. It is inserted into the untwisted tube piece, where it is untwisted. The control segment 18 is now further swiveled by the step motor 22 and operates the yarn transfer device 26 via the control rod 44, which pulls the prepared yarn end from the holding and untwisted tube piece. The splicing prisms 32 are positioned so as to overlap each other in the splicing passages of the splicing prisms 32. That is, the arm of the yarn transfer device 26 catches a bundle of upper yarns or lower yarns on the side opposite to the holding / untwisting pipe piece to which it belongs, and forms a loop in the yarn. Alternatively, based on the control of the step motor 22, the yarn end is pulled from the holding / untwisted tube piece toward the splicing passage of the splicing prism by the yarn transferring device. In this case, the yarn transfer device 26 is adapted to optimally overlap the two yarn ends pulled back into the splicing passage with each other, for example, in a predetermined state set in the central control unit of the automatic winder 1 at the start of lot exchange. It can be turned.

  When the yarn ends are overlaid in an optimal state depending on various yarn parameters, for example yarn material or yarn number, splicing air is fed into the splicing passage which is closed by the cover member 25 and thereby the splicing passage. Both yarn ends positioned within are entangled with each other by aerodynamic forces. The control segment 18 is then swung back to the starting position again by the step motor 22 to open the yarn clamping and cutting device 23 and the cover member 25, so that the pneumatically coupled yarn is released. The winding process is started again.
