Description

Round shuttle loom

The present invention relates to a circular shuttle loom and to a method of replacing a weft tape bobbin on a circular shuttle loom.

In general, there are known circular shuttle looms in which a warp tape guide (for example in the form of a length balance compensator) is placed around the circular turn of the circular shuttle loom. A plurality of circumferentially distributed warp yarn strips are fed across the warp tape guides or through the warp tape guides to the circular shuttle loom. From the warp tape guides, the warp tapes extend to the shed forming device, for example, having strands or tapes that are provided for respectively passing through the lugs of a warp tape; thereafter, the warp tapes are extended Between the masts of the circular cymbal. The warp tapes are then divided into two warp tape sets at the shed forming devices, most often in alternating settings, for which there is a relative alternating action imparted by the relative movement of the strands or bands, whereby The shed (also representing the travel shed) is opened and closed. In the open state, the shed forms a space defined by the set of two warp tapes, wherein the weaving shuttle moves on a circular path along the circular turn so that the weft tape carries the weft tape from it The bobbin is pulled out and introduced into the shed. The space of the shed defined by the two warp tape sets is constantly changing as the movement of the two warp tape sets. When the two warp tape sets are all on the same surface, the shed is closed and the space size is zero; when the two sets of warp yarn strips are at the relative turning points of their alternate movements, the space size reaches a maximum value. At these turning points, the so-called shed change is initiated by changing the direction of movement of the groups of relatively oriented warp yarns, whereby the finally introduced weft tape is fixed in the fabric and the next weft tape can be borrowed The shed is introduced by the next shuttle. A plurality of weaving shuttles are typically circumscribed within the circular cymbal at a uniform distance from one another. The resulting tubular fabric is fed inwardly toward the centrally disposed woven loop and deflects the fabric toward the rolls at the woven loop.

There are more conventional circular shuttle looms in which the weaving shuttle maintains the longitudinal axis of the weft tape bobbin parallel to an axis extending orthogonally to a tangent to the circumferential direction. Thus, the longitudinal axis of the weft tape bobbin is substantially laterally disposed on the weaving shuttle in the circumferential direction of the weaving shuttle.

A circular shuttle weaving machine in which the longitudinal axis of the weft threaded bobbin is substantially transverse to the circumferential direction is known, for example, from the patent application EP 2 829 645 A1.

By virtue of these conventional embodiments of circular shuttle weaving machines, it has proven to be disadvantageous that due to the configuration of the circular shuttle weaving machines, the weaving shuttle can only carry weft threaded bobbins having a limited number or length of weft tapes, respectively. As such, the weft belt bobbin must be replaced from time to time. Replacing the used weft tape bobbin with a complete weft tape bobbin is very time consuming and is generally done manually by closing the circular shuttle loom, so temporary production downtime will occur during this replacement process. However, it is also disadvantageous that errors may occur due to inadvertent handling by manual replacement, thereby affecting the quality of the fabric, or it may therefore occur that the weaving machine is completely shut down.

Accordingly, it is an object of the present invention to provide a circular shuttle loom that can be used for a longer period of time without manual intervention than the circular shuttle loom as is known in the prior art. A further object of the invention is to improve the average weaving performance of the circular shuttle loom as well as its throughput.

According to the invention, this task is solved by a circular shuttle loom having the features of claim 1 of the patent application. Preferred embodiments of the invention are indicated in the scope of their dependent claims.

With the circular shuttle loom according to the present invention, the used weft tape bobbin can be automatically replaced with the complete weft tape bobbin by the weft belt bobbin changing device formed on the circular shuttle loom. Due to the automatic replacement, the period during which the weft tape bobbin is replaced is shortened, so that the down time is also reduced, so that the average weaving efficiency of the circular shuttle loom is improved. In order to replace the weft tape bobbin, the weft tape bobbin changing device and the at least one bobbin clip are moved relative to each other into the replacement position. Since the weft tape bobbins are disposed on the respective weaving shuttles of the circular shuttle weaving machine, and the configuration of the applicable weft tape bobbin changing device is advantageous, the weft tape bobbin changing device replaces the finished weft tape bobbins into complete The weft belt bobbin only needs to be moved a short distance, so the replacement can be achieved very quickly. There is preferably a pull member and a fixing member formed on the weft tape bobbin changing device, wherein the pulling member is configured to pull the used weft tape bobbin from the bobbin clamp along its longitudinal axis, and Wherein the fastener is configured to place the complete weft tape spool along the longitudinal axis thereof. For this purpose, the pull member and the fixing member can be advantageously formed by different types of creels, bobbins, yarn splitters and/or hooks which are controlled electromagnetically, pneumatically or hydraulically.

In a simple embodiment, when the weft tape bobbin is replaced, the pulling member pulls the warp tape set to open an opening in the warp tape set, and the used weft tape bobbin is replaced by the opening. The complete weft with a bobbin. In a preferred embodiment, the openings in the sets of warp tapes are formed by an opening mechanism that is specifically provided for this purpose. The opening mechanism is advantageously attached to the weft tape bobbin changing device or the circular weir. The opening mechanism pulls the warp tape sets apart before replacing the weft tape bobbins, so that the thus formed opening is opened during the entire replacement process. The opening mechanism is thus preferably formed by a winder and/or a telescopic rod that is controlled electrically, electromagnetically, pneumatically or hydraulically.

The weaving shuttle is advantageously in an idle position when the weft belt bobbin is replaced. When the circular weir of the conventional circular shuttle loom has the upper and lower hoops of the weaving shuttle in the circumferential path as the weaving guide and wraps in the circumferential direction, it is to be replaced before replacement The weft tape bobbin is moved to the hairline direction of a surface which is the surface developed by the tangent of the weft of the weft and the longitudinal axis of the weft tape bobbin. This essentially corresponds to the movement away from the circular file in the direction of the weaving ring. For this purpose, the bobbin clamp is configured to slide over the weaving shuttle or the entire weaving shuttle is moved in the direction of the weaving loop. In this way, it is excluded that the weft tape bobbin is covered by the parts of the weaving machine, in particular the circular weir, during the replacement process.

The weft tape bobbin changing device usefully has a replacement rotator that forms a cartridge for receiving a plurality of full weft tape bobbins and a cartridge for receiving a plurality of used weft tape bobbins. Preferably, the complete weft tape bobbins are disposed adjacent one another along their longitudinal axes, coaxial with the longitudinal axis of the cartridge for receiving the complete weft tape bobbins, and the finished weft tape bobbins are along its longitudinal direction The shafts are disposed adjacent one another and are coaxial with the longitudinal axis of the cartridge for receiving the finished weft belt bobbins. This provides the advantage that the weft belt bobbin changing device can be configured in a compact manner, which is particularly advantageous for smaller circular shuttle looms due to limited space requirements. Depending on the embodiment, the height or length of the cartridges can be varied separately, so that the available spatial composition can be utilized as optimally as possible.

In order to facilitate the filling or emptying of the cartridges, the entire replacement rotator can be pivoted from the working position to the loading or unloading position, and the trained personnel can load or empty the exterior of the circular shuttle loom. Cylinder.

The replacement rotary device is advantageously mounted for rotation, and each of the longitudinal axes of the cartridges are disposed in parallel at a distance from the axis of rotation of the replacement rotator. It has further been verified that it is advantageous to arrange the replacement rotator in the circular shuttle loom such that the rotational axes of the replacement rotators are oriented parallel to the longitudinal axis of the tubular clamp, whereby each Each of the cartridges may be coaxially aligned with the longitudinal axis of the preferably cylindrical tubular clamp by rotation of the replacement rotator about the rotating shaft. This provides the advantage that the replacement of the used weft tape bobbin into the complete weft tape bobbin can be carried out quickly and the unnecessary travel distance can be omitted.

Figure 1 shows schematically an embodiment of a circular shuttle loom 1 according to the invention, and for a better overview than a true scale. The circular shuttle loom 1 comprises a frame 2 of a polygonal configuration, which is preferably formed by a plurality of molds welded to each other, representing the mounting for the entire circular shuttle loom 1. At the center of the frame 2, a circular cymbal 4 formed as a cylinder in this embodiment is disposed on the frame 8. In the circular cymbal 4, a plurality of weaving shuttles 6 are wound around the circular cymbal 4. A woven ring 5 concentric with the circular cymbal 4 is disposed within the circular cymbal 4, and the finished tubular fabric 10 is subsequently detached through the woven loop 5. On the outside of the circular cymbal 4, a feed 7 for the warp tape 9 is arranged on the circumference. The circular shuttle loom 1 further has a weft tape bobbin changing device 3 which accommodates a cartridge 21 for accommodating the entire weft tape bobbin 22 and a cartridge for accommodating the used weft tape bobbin 24 by the replacement rotator 20. 23 (not depicted in Figure 1). The entire weft belt bobbin changing device 3 is rotatably mounted about a horizontal axis 36 and is pivotable between a working position and a loading and unloading position. In Fig. 1, the weft tape bobbin changing device 3 is in this working position. In the embodiment depicted in Fig. 1, the cartridges 21, 23 are disposed in the vertical direction above the circular jaw 4 in the working position.

Fig. 2 is a schematic detailed front view of the circular shuttle loom as shown in Fig. 1. The feed 7 of the circular shuttle loom 1 has a plurality of warp tape guides 11 formed as length balance compensators, and each comprising a lug for passing and deflecting a warp tape 9. The warp tape guides 11 are distributed around the circular turns 4 of the circular shuttle loom 1. The circular cymbal 4 includes an upper hoop 4a and a lower hoop 4b interposed between the upper hoop 4a and the lower hoop 4b, and the plurality of shanks 4c are disposed at equal intervals from each other. The upper hoop 4a and the lower hoop 4b represent the guides for the weaving shuttle 6 during the process in which the weaving shuttle 6 is wound around the circular weir 4. The warp tape 9 passes through the warp tape guide 11 and passes through the spaced masts 4c from a warp tape bobbin located outside the frame 2 and not depicted herein.

The feed 7 further has a shed forming device 12 which is disposed around the circular warp 4 between the warp tape guide 11 and the circular turn 4. The shed forming device 12 includes a plurality of first strands 13 and second strands 14, which are joined to each other at both ends and enclose the upper roll 15a and the lower roll 15b. Each of the first strands 13 has a lug 13a through which the warp yarns 9 are passed. The warp tapes passing through the lugs 13a of the first strand 13 form a first warp tape set 17. Each of the second strands 14 has a lug 14a through which the warp yarns 9 are passed. These warp tapes that pass through the lugs 14a of the second strand 14 form a second warp tape set 18. At least one of the upper roll 15a and/or the lower roll 15b alternately rotates in the first and opposite second directions of rotation, whereby the strands 13, 14 enclosing the strips are alternately moved up and down. Thus, the alternating upward and downward movements are given to the two warp belt sets 17, 18, thus the switch shed 16 (also representing the travel shed). The shed 16 in the open state forms a space defined by the two warp tape sets 17, 18, wherein the weaving shuttle 6 not depicted in this view moves along the circular path of the circular cymbal 4 in the circumferential direction 37, The weft tape 34, not depicted in Fig. 2, is thus pulled out of its loaded weft tape bobbin 19 and introduced into the shed 16 to form the tubular fabric 10. The shed 16 is closed when the strands 13, 14 are in an intermediate position, wherein the first strands 13 and the lugs 13a, 14a of the second strand 14 are at the same height, whereby the warp yarn sets 17, 18 are both in the same This surface 16a is formed on the surface 16a or separately.

The weft tape bobbin changing device 3 in the illustration depicted in Fig. 2 is in the loading and unloading position. In the loading and unloading process of the weft tape bobbin changing device 3, the circular shuttle loom 1 is preferably operated under a weaving operation. Thus, the person can load the full weft tape bobbin 22 with the cartridge 21 for the complete weft tape bobbin 22, and remove the used weft tape bobbin 24 from the cartridge 23 for use of the weft tape bobbin 24, and Uninterrupted production. For the sake of clarity, Figure 2 depicts only the cartridge 21 for the complete weft tape bobbin 23. The replacement rotator 20 is rotatably mounted in the mount 25 about the rotating shaft 40. Each of the cartridges 21, 23 is disposed in parallel with the rotary rotator 20 at a distance from the rotary shaft 40 at a longitudinal axis thereof. By rotating the replacement rotator 20 in the working position about the axis of rotation 40, the longitudinal axes of the cartridges 21, 23 define a section of a circle 31. See Figure 3. The weft tape bobbin changing device 3 further has a weft tape connecting device 26 attached to the replacement rotator 20 by a cross-sectional hollow shaft 27. The weft belt bobbin changing device 3 comprises a suction unit, a coupling unit and a separation unit, which are not depicted in more detail.

Figures 3 through 9 show the replacement of the used weft tape bobbin 24 with the complete weft tape bobbin 22. As illustrated in Fig. 3, one of the weaving shuttles 6 maintains the weft threaded bobbin 19 rotatable about its longitudinal axis, whereby the longitudinal axis of the weft threaded bobbin 19 remains substantially vertical in this embodiment. As such, the weft tape bobbins move laterally within the circular ridge with its longitudinal axis to a circumferential direction 37, wherein the longitudinal axes thereby define a circle 32.

The sensor unit attached to the circular cymbal 4 and not depicted in the drawings is preferably continuously measuring the load of the currently used weft belt bobbin 19 during the bypass. This can be achieved, for example, by an optical sensor. If the sensor detects that the weft tape bobbin 24 is used up, the longitudinal axis of the weft tape bobbin 24 and its corresponding weaving shuttle 6 are stopped by one of the main drives of the circular shuttle loom 1 not depicted. Replace position 30. The replacement position 30 corresponds to an intersection between the segments of the circle 32 and the circle 31. In a further step, the replacement rotator 20 rotates the longitudinal axis of the cartridge 23 for use of the weft tape bobbin 24 to the replacement position 30 by a starter drive (e.g., a stepper motor). Thus, the longitudinal axis of the used weft tape bobbin 24 and the longitudinal axis of the cartridge 23 for use of the weft tape bobbin 24 are disposed coaxially with each other. See Figures 3 and 4.

In order to replace the weft tape bobbin 19, the opening in the first warp tape set 17 will be produced by the weft tape bobbin changing device 3, which has not been drawn and is mounted to the weft tape changing device 3 or mounted on a circular cymbal 4 Opening mechanism. This can be achieved, for example, by a telescopic rod that extends hydraulically or pneumatically or by a crepe. The cartridge 23 can be slidably received in the replacement rotator 20 along its longitudinal axis in this embodiment. The cartridge 23 thus advantageously moves pneumatically, electromagnetically or hydraulically along its longitudinal axis. This can be achieved, for example, by a pneumatic cylinder, hydraulic cylinder or lifting shaft equipped with an electric motor. For the sake of clarity, these elements are not illustrated in the drawings. By the downward movement of the cartridge 23, this is applied to the used weft tape bobbin 24 located on the weaving shuttle 6, whereby the spring-loaded wedge fastener engages the used weft tape bobbin 24. In the present embodiment, the cartridge 23 and the spring-loaded wedge fasteners form the pull member. The spring-loaded wedge fasteners are disposed within the cartridge 23 and project beyond the otherwise smooth inner side 29 of the cartridge 23 in the normal position; thus, once the weft cartridge has been used, the cartridge 23 is introduced and immediately forms everything. Undercut. During the subsequent upward movement of the cartridge 23, the used weft tape bobbin 24 is pulled out of the bobbin holder 28 of the weaving shuttle 6 and housed in the cartridge 23 as illustrated in Fig. 5.

After the used weft tape bobbin 24 has been removed from the bobbin holder 28, the weft tape 34 is then sucked into the cross-sectional hollow shaft 27 by the suction unit integrated therein. Thus, by replacing the rotation of the rotator 20, the cartridge 21 is rotated about its longitudinal axis to the replacement position 30, whereby the cartridge 21 is aligned coaxially with the longitudinal axis of the cylindrical tubular clamp 28. See Figure 6. The weft end portion 33 of the next complete weft tape bobbin 22, which is placed on the bobbin holder 28 by the weft tape bobbin changing device 3, will be sucked in by the suction unit of the weft tape joining device 26. The weft tape 34 and the weft tape end 33 are brought into a position by the suction unit, wherein they can be joined by a joining unit integrated in the weft tape joining device 26. Depending on the embodiment and the material of the weft tape, the bonding unit is formed, for example, by a welding device, a bonding device, a knotting device and/or a sewing device. Preferred weft tape materials in this regard are, for example, different types of plastic, natural or rayon. When the weft tape 34 is joined to the weft end end 33, the trailing end of the weft tape which is not depicted in Fig. 7 of the used weft tape bobbin 24 is separated by the separating unit (the rotatably mounted knife) Thus, a new weft tape 35 is formed. See Figure 8.

Figure 8 shows the weft tape bobbin changing device 3 in the process of placing the complete weft tape bobbin 22 in the bobbin holder 28. In order to place the complete weft tape bobbin 22, the weft tape bobbin changing device 3 has a fixing member. In the present embodiment, this is formed by a fixed shaft 38 that is axially slidably mounted within the cartridge 21. The actuation of the fixed shaft 38 in this axial direction is advantageously achieved pneumatically, electromagnetically or hydraulically. This can be achieved, for example, by a pneumatic cylinder, hydraulic cylinder or lifting shaft equipped with an electric motor. For the sake of clarity, these elements are not illustrated in the drawings. A fastener not depicted is attached to the fixed shaft 38 or to the fixed shaft 38. The fastener pulls the complete weft tape bobbin 22 from the cartridge 21 during the downward movement of the fixed shaft 38 and places it. On the bobbin holder 28. The inner tube of the cylindrical bobbin holder 28 and the complete weft belt bobbin 22 advantageously has a transition fit, whereby the weft belt bobbin 19 is held in a frictional connection during the winding of the weaving shuttle 6 On the bobbin holder 28. This transitional match is advantageously selected such that the used weft tape bobbin 24 or the full weft tape bobbin 22 can be easily placed on or unplugged from the bobbin holder 28 without being in a round 筘4 These forces developed during the bypass of the weaving shuttle 6 result in the release of the weft threaded bobbin 19. In yet another embodiment, the spring element can also be attached to the barrel clamp 28 which extends beyond the cylindrical side of the barrel clamp 28 and is pressed into the respective recess, wherein the weft threaded tube 19 is placed in the barrel clamp 28 on. Thus, by the spring elements, a frictional connection is ensured between the bobbin holder 28 and the complete weft belt bobbin 22. During the downward movement of the fixed shaft 38, the pinch shaft 39 formed at the front end thereof engages a corresponding opposing member in the cylindrical tubular clamp 28, thereby forming a tangent between the fixed shaft 38 and the tubular clamp 28. Forms of mating connections. A front end having a bolt shaft 39 formed thereon is rotatably attached to the fixed shaft 38. The complete weft tape bobbin 22 is placed on the bobbin holder 28 by the front end passing through a rotation of an unillustrated electric motor (preferably embodied as a servo motor) opposite to the unwinding direction of the weft belt bobbin 19. After that, the new weft tape 35 is unfolded. Thus, the complete weft tape bobbin 22, which has just been placed on the bobbin holder 28, is released by the fasteners not formed on or in the fixed shaft 38, and the fixed shaft 38 returns to its starting position. See Figure 9. Thus, the replacement procedure of the weaving shuttle 6 is completed, and the next weaving shuttle 6 having the used weft tape bobbin 24 is moved into the replacement position 30 by the rotation of the main driving member not drawn by the circular shuttle loom 1. This procedure is repeated until all of the used weft tape bobbins 24 are replaced. Once all of the weft tape bobbins 24 have been replaced, the circular shuttle loom 1 immediately continues the weaving process.

According to a further embodiment, the weaving shuttle 6 is wound around a cylindrical circular beak 4. The circumferential area of the weaving shuttle 6 is thus formed as a circular ring area. In the present embodiment, the cartridges 21, 23 are thus advantageously placed in the working position in the horizontal direction.

According to a further embodiment, the circular cymbal 4 is formed in a conical shape, wherein the woven shuttle 6 is substantially circumscribed on the inner face of the truncated cone.

According to a further embodiment, the circular shuttle loom 1 comprises a plurality of weft belt bobbin changing devices 3. Thus, the advantage of having a plurality of weaving shuttles 6 to replace the weft tape bobbin 24 with the complete weft tape bobbin 22 can be performed simultaneously, thereby reducing the downtime of the circular shuttle loom 1.

According to yet another embodiment, the new weft tape 35 is not unfolded by the rotation of the fixed shaft 38, but by an electric motor that is coupled to the bobbin holder 28 and disposed on the weaving shuttle 6.

According to yet another embodiment, the plastic sheet is welded to the weft end end 33 of the complete weft tape bobbin 22. When the cartridge 21 for the complete weft tape bobbin 22 is loaded, the plastic sheet is hooked into the feed, whereby the position of the weft end portion 33 is defined as being accommodated in the cartridge 21 in the weft tape bobbin changing device 3. Each complete weft has a bobbin 22.

Although the technical content of the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and any modifications and refinements made by those skilled in the art without departing from the spirit of the present invention are encompassed by the present invention. The scope of protection of the present invention is therefore defined by the scope of the appended claims.
