Description
Technical Field
The present invention relates to a shuttle for a circular weaving machine; in particular, it relates to a weft unwinding and tensioning system, and to a circular weaving machine shuttle comprising a shuttle pad assembly and a circular weaving machine equipped with a shuttle carrying the shuttle pad assembly.
Background
Circular weaving machines have been considered as one of the most practical weaving machines for producing tubular fabrics, which are preferentially used as base fabrics for the production of transport or storage containers for particles such as grains, sugar, fertilizers, polymer particles and chemicals.
In the known circular knitting machine, an even number of shuttles are mounted on an endless shuttle guide member so that they can travel along the guide member. Engagement means such as press rollers, which are respectively engaged with the corresponding shuttles, move along the shuttle guide members. Each shuttle is pressed by the corresponding engagement means and advanced along the shuttle guide member. The weft yarns taken out of the respective shuttles are made of warp yarns which are opened in sequence on the upper and lower sides of the respective shuttles by heddles, thereby forming a tubular fabric.
In a circular loom, in order to improve the production efficiency, it is necessary to use a so-called large package bobbin. However, since it is obvious that if the size of the yarn package becomes large, there is a difference in unwinding characteristics of the entire bobbin diameter particularly when the bobbin diameter is reduced below a certain size.
In the case of shuttles for circular weaving machines, for example for tubular bag manufacture, it is customary to attach a flap to the weft bobbin body, which flap is pressed by a spring against the bobbin thread. The flap, which moves about the fulcrum, covers the leather or felt and pivots about the coil axis all the time as the bobbin winding decreases. This therefore results in a reduction in the braking force or pressure applied towards the end of the winding. However, different wires or strips that have been processed in circular weaving machines require different braking forces. For example, slit film strip material made of polypropylene is somewhat stiffer and rougher than the softer, smoother strips made of polyethylene material. The braking force generated by the pressure pad (or brake pad) acts directly on the wire or strip, and the continued abrasion may cause damage to the brake material. This may further lead to uneven tension control if the pressure pad is not replaced regularly. Furthermore, it may damage the weft tape. Changing the pressure pad results in a decrease in the productivity of the loom and expense on the consumables.
The WIPO publication WO2010084074a1 discloses a device for controlling the tension of weft tape on a shuttle, a shuttle and a circular weaving machine equipped with the device. The present disclosure refers to brake linings used in shuttles configured in circular weaving machines and how the pressure exerted by the brake linings helps to create tension in the weft thread.
Another document, us patent 4365651, also discloses a shuttle for circular weaving machines. In particular, the present document discloses a shuttle provided with an improved structure to be easily mounted on or dismounted from the circular weaving machine, while providing a stable structure capable of supporting large-sized bobbins. It is by the way an element 51 (see fig. 6 and 8A of the document) which is able to always maintain the braking action on the bobbin in order to provide sufficient yarn tension for the weft yarn.
However, neither document WO2010084074a1 nor US4365651 mentions wear or the need for frequent replacement of the brake lining itself, and its adverse effect on the fabric production. It also does not provide a solution to the problems widely faced by the industry.
Accordingly, there is a need for an alternative shuttle pad assembly system configured with a pressure pad assembly that has enhanced wear resistance and is gentle to the weft material. Furthermore, there is also a need for a cost-effective system with a long service life.

Detailed Description
The unwinding tension of the yarn wound around the bobbin (B) is a very important criterion for determining the quality of the product. It has been observed that the nature and magnitude of the variation in the yarn tension depends on the size of the bobbin (B) at the beginning and at the end of the unwinding process. The tension increases with the loss of the bobbin (B) and the increase of the unwinding speed of the bobbin (B). During the weaving of a circular loom, the weft yarn unwinding tension is transmitted by a shuttle pad assembly (S) during the production processA) And (5) controlling. Shuttle cushion assembly (S)A) Pivoting about a pivot point with the aid of a tension spring mounted on the shuttle body. Shuttle cushion assembly (S)A) There is also a mechanism to control the speed of the rotating bobbin, typically a pressure pad assembly (2) that presses on the surface of the weft bobbin (see fig. 1).
The surface of the pressure pad assembly (2) in contact with the winding bobbin (B) is subjected to friction by the yarn being unwound. The material of the contact surface should be such that it does not cause damage to the yarn. At the same time, the material should be such that it does not wear out by friction on its own. Typically, provided in the shuttle pad assembly (S)A) The pad assembly (2) in (1) has a pad lining (2A) made of leather or felt, and the pad lining (2A) presses on the weft bobbin. Such materials are generally found to be harmless to the yarn, however, it has been found that the contact surface of the pad backing (2A) wears due to the constant abrasion with the yarn as the weft yarn passes through the pad made of felt or leather. This results in frequent changing/replacement of the pad linings (2A) depending on the type of yarn material of the weft bobbin (B).
The shuttle pad assembly (S) of the present invention will now be explainedA) General work of (1). Fig. 1 shows the bobbin (B) and shuttle pad assembly (SA) being unwound. It shows a pressure pad assembly (2) as part of a shuttle pad assembly (SA), the pressure pad assembly (2) being rolled upPressure is applied to the outer face (7) around the bobbin (B). The pressure pad assembly (2) comprises a pressure pad receiver (2B), on which pressure pad lining (2A) is mounted. A connecting or tension arm (1) connects the pressure pad assembly (2) to a pivot mechanism (3), which pivot mechanism (3) is in turn fixed to the shuttle body carrying the bobbin. The pivot mechanism (3) is in turn connected to a fixed support (5), which fixed support (5) is also fixed to the shuttle body by means of a tension spring (4). As shown in fig. 1, the deformation of the tension spring (4) generates tension in the tension arm (1). The pressure pad assembly (2) thus presses on the weft bobbin (B), preventing uncontrolled free rotation of the weft bobbin (B), which in turn results in a predetermined amount of tension in the weft thread.
The diameter of the weft bobbin (B) is gradually reduced as the weaving production process proceeds. At the beginning, the outer diameter of the winding package for the full winding size of the weft yarn bobbin is about 110mm to 90mm (indicated by D in FIG. 1)1Indicated) and toward the end, the outer diameter of the empty bobbin is about 35mm to 40mm (indicated by D in fig. 1)0Representation). On a newly installed full capacity weft bobbin (B), the shuttle pad assembly is designed to exert pressure on the outer surface (7) of the full bobbin (B) through its pad-pressing patch (2A). At this stage, the tension spring (4) is deformed to L1. Over time, as the weft bobbin diameter decreases, the brake pad now acts on the outer surface (7) of the bobbin (B) of decreasing diameter D0, and the spring deformation decreases to L0. At this time, the traction force to overcome the frictional force and tension force generated by the pressure pad assembly (2) is also reduced.
The invention discloses a shuttle cushion assembly (S)A) The shuttle pad assembly (SA) comprises a pressure pad assembly (2) that is not harmful to the yarn and itself. A pressure pad assembly (2) is provided at one end of the tension arm (1). The pressure pad assembly (2) has a pressure pad lining (2A) mounted on a pressure pad receiver (2B), which pressure pad receiver (2B) is connected to the tension arm (1). Fig. 2 shows a pressure pad assembly (2) of the present invention. The tension arm (1) connects the pressure pad assembly (2) to a pivot mechanism (3), which pivot mechanism (3) is fixed to the shuttle body (indicated by S)B). The pivot mechanism (3) is in turn connected to a fixed support (5) by a tension spring (4). A press pad lining (2A) passes throughAny one of a plurality of arrangements selected from a screw-mounting type, or an adhesive type, or a press-fitting clamping type, or a combination thereof is mounted on the pressure pad receiver (2B).
The press pad lining (2A) of the present invention is made of a wear resistant material such as metal (e.g., stainless steel or alloy steel). They may be made of sheet metal or formed by machining a solid block of metal. The texture of the outer surface (6) of the pad facing (2A) that contacts the bobbin (B) is very important. The outer surface (6) is polished to reduce its coefficient of friction as much as possible, preferably to between 0.1 and 0.25. Alternatively, the pressure pad backing (2A) may be made of any material that is a substrate and may be provided with a wear/abrasion resistant coating thereon using a variety of techniques such as nitriding, or hard anodizing, or chrome plating or plasma electrolytic oxidation, or chromium carbide, or chromium oxide, or tungsten carbide, or ceramic coating. The roughness Ra of the coating surface is preferably between 0.1 and 2.3 micrometers.
The shape or curvature of the outer surface (6) of the pad insert (2A) is also important-it is desirable to minimize the contact area between the outer surface (6) and the outer surface (7) of the bobbin (B) being unwound. For this purpose, the outer surface (6) has a preferably curved cross-sectional geometry as shown in fig. 3. As shown in part (a) of fig. 3 and fig. 4, a single ridge is provided in the pad patch (2A), the ridge being arranged over the entire length of the pad patch (2A). In one aspect of the invention, the pressure pad lining (2A) may have a multi-humped contact surface (6). The outer surface (6) may have a double ridge, as shown in part (b) of fig. 3, or it may have a linear shape, as shown in part (c) of fig. 3. The curved shape is preferably convex.
The pad linings (2A) are mounted on the pad receivers (2B) by any of a variety of arrangements or combinations thereof. The mounting arrangement may be screw mounted or the pad backing (2A) may be attached to the pad receiver (2B) using a suitable type of glue. The pad insert (2A) may be shaped such that it may be in the form of a clip that may be press-fitted onto the receptacle (2B).
In another aspect of the invention, a shuttle pad assembly (S) is disclosedA) Has already been pressed to the pad lining (2A)A wear resistant treatment, such as a plasma electrolytic oxidation coating or a carbide coating, is provided to achieve a very long service life. In some cases, the substrate of the shuttle pad backing sheet may be a wear resistant plastic such as PEEK, acetal, or UHMW.
Example (c): a pressure pad made of stainless steel is used in the shuttle of the circular weaving machine. A 500mm wide cylindrical fabric was made using a bobbin carrying slit film tape yarn. The fabric is made using a shuttle pad assembly configured with a conventional brake pad lining made of leather/felt and a separate pad lining of the present invention. It was observed that after 15 to 22 hours, the conventional brake linings need to be replaced, while at the end of 300 hours, the pad linings of the invention are still in use.
Further experimental data indicate that the service life of a shuttle pad assembly equipped with a felt-type brake lining is about 10 hours to 24 hours, whereas the shuttle pad assembly (S) equipped with a wear-resistant pressure pad lining (2A) according to the inventionA) The service life of (2) is more than 30 days. This results in an increase in the productivity of the loom and an improvement in the quality of the circular fabric with a smaller width variation.
The invention also discloses a shuttle assembly comprising the shuttle pad assembly. The shuttle pad assembly of the present invention requires less frequent replacement of the pad linings (2A) than prior art shuttles equipped with brake pads.
The present invention also discloses a circular weaving machine which uses the shuttle pad assembly disclosed herein to configure a shuttle. The loom of the invention requires less stoppage for replacing the brake pad lining (2A).
While the above description contains many specificities, these should not be construed as limitations on the scope of the invention, but rather as exemplifications of preferred embodiments thereof. It must be appreciated that variations and modifications can be made based on the disclosure set forth above without departing from the spirit and scope of the invention. Thus, the scope of the invention should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents.
