Description

DETAILED DESCRIPTION OF THE INVENTION <<Industrial Application Field>> The present invention relates to a method for manufacturing a wick for a combustion appliance used in an oil stove, an oil stove, etc. that use kerosene as fuel.

《Prior art》 This kind of conventional wick for combustion appliances has a heat-resistant combustion wick made of glass fiber or a thick fabric of glass fiber and carbon fiber blend on the upper part of the fuel suction part made of cotton thread or a thick fabric of cotton and rayon blend. When forming the fuel suction part, a woven fabric is woven with the warp and weft to a constant weaving width G on a loom as shown in Fig. 12. Bent portion 31 formed only by fabric portion 30 and warp yarns
are continuously formed into a belt shape, and further a woven fabric portion 30 is formed.
Both ends 33, 33 of the cloth G through the cutting part 32
It is known that a cylindrical fuel suction part is formed by connecting the two. Further, as shown in FIG. 13, a cylindrical core made by connecting and stitching a plurality of fiber bodies 35 is known, for example, from Publication of Utility Model Publication No. 46-24522 or Publication of Utility Model Publication No. 43-16157. There is.

<<Problems to be solved by the invention>> By the way, the wick for a combustion appliance illustrated in FIG.
When forming the fuel suction part, the loom width G is wide and the weft width is long during weaving, so the rotation speed of the loom is approximately
Productivity is limited to 60 to 120 times per minute, resulting in extremely low productivity and inefficiency.In addition, dimensional variations tend to occur and the defective rate is high.In addition, the core shrinks during use and gets stuck in the core guide tube of the instrument, making it difficult to lift and lower the core. Problems are likely to occur due to defects. In other words, it is not possible to adjust the firepower by raising and lowering the wick, and the fire does not line up evenly due to deformation of the wick or unstable dimensions when attached to the device. There were drawbacks such as the need to make changes. In addition, in the case shown in FIG. 13, the plurality of fiber bodies 35 are formed by cutting a wide fiber cloth, so when processing the plurality of fiber bodies 35 by aligning them in parallel and integrally connecting them to form a cylindrical core body. Care must be taken to ensure that the entire periphery of the fiber body 35 does not become frayed, which may result in poor work efficiency and unstable dimensions, making it impossible to smoothly attach the fiber body to the appliance. When a plurality of fibrous bodies 35 are joined to 36, several seams 37 are formed, resulting in disadvantages such as flames not being uniformly aligned.

This invention solves the above problems, and has good fuel suction efficiency, is easy to manufacture, can be mass-produced at low cost, and can smoothly move the wick up and down over a long period of time, as well as eliminate uneven combustion. The purpose of this invention is to obtain a wick for a combustion appliance that is convenient to use.

<Means for Solving the Problems> In order to achieve the above object, the method for producing a wick for a combustion appliance of the present invention uses warp and weft yarns made of fibers having good fuel absorption properties such as cotton fibers. A continuous wide part 1 having a warp and a weft and a wide bent part 2 without a weft are sequentially woven to form a continuous belt-shaped fuel wicking core band 3, and then the continuous wide part 1 is cut. A large number of split fuel wicks 6 each having a wide upper part 4, a wide bending part 2, and a narrow hem part 5 are formed, and then the upper wide part 4 and the narrow hem part of the split fuel wick 6 are formed. Several pieces of the split fuel wick 6 are butted and sewn together via the first sewing thread 7 to form the fuel wick 8.
Next, the upper edge of the fuel wick 8 and the lower edge of the heat-resistant combustion wick 9 formed of heat-resistant fibers such as glass fibers are butted together and sewn together via the second sewing thread 10 to form a flat core 11. is formed, and then both ends of the flat core 11 are abutted and sewn together via the third sewing thread 12 to form a cylindrical core 13.

<<Embodiment>> An embodiment of the present invention will be described below with reference to the drawings. 1 is a continuous wide part, which is woven with warp and weft made of fibers with good fuel absorption properties such as cotton fibers, and the warp and weft are woven together. A continuous wide part 1 with a weft and a wide bent part 2 without a weft were sequentially provided to form a continuous band-like shape, and a weave width B as shown in FIG. 1 or a weave width C as shown in FIG. 8 was obtained. The fuel wicking core band 3 is formed, and then the continuous wide part 1 is cut through the cutting strip part 14 to divide it into multiple pieces each having an upper wide part 4, a wide bent part 2, and a narrow bottom part 5. The fuel wick 6 is formed, and then the side edges of the upper wide part 4 and the narrow bottom width part 5 of the split fuel wick 6 are butted together and the split fuel wick 6 is attached via the first sewing thread 7. Several sheets are sewn together to form a fuel wick 8, and then the upper edge of the fuel wick 8 and the lower edge of a heat-resistant combustion wick 9 made of heat-resistant fibers such as glass fibers are butted together using a second sewing thread. 10 to form a flat core 11 as shown in FIGS. The cylindrical core 13 is sewn together via the thread 12 in FIGS. 3, 5, 7, and 10.
It is formed as shown in the figure.

Further, 15 is a notch, and 16 is a split formed without sewing the entire side edge of the butted upper wide parts 4, 4 and without sewing the middle part, and the notch 15 and the split 16 Even if the cylindrical core 13 is used for a long period of time, the fuel suction core 8 will not shrink and bite into the core guide tube (not shown), making it impossible to move the core up and down. In addition, the fuel wick 8 may be subjected to a flame-retardant finish 18 to impart heat resistance as shown in FIG. By applying a water-repellent finish 19 to the lower part, a heat-resistant and waterproof fuel wick 8 can be obtained. Further, as shown in FIG. 11C, the entire fuel wick 8 may be given a water repellent finish 19 and only the upper part may be given a disaster prevention finish 18, and these treatments are performed before the heat-resistant combustion wick 9 is sewn together. This prevents deformation of the core body due to contraction of the fuel suction core 8. 17 is a reinforcing tape.

<<Operations and Effects of the Invention>> The present invention has the above-described configuration, and provides the following operations and effects.

(1) The number of split fuel suction cores 6 can be freely selected according to the outer circumferential dimension of the core guide tube (not shown), which varies depending on the model, so the loom width G can be changed for each model as in the past. Products of different sizes can be easily produced without need.

(2) As shown in FIG. 1, the weave width B or 8 is particularly narrower than the conventional weave width G shown in FIG. 12.
Since continuous weaving is possible with the narrow weaving width C shown in the figure, the loom can be woven at a rotation speed of approximately 800 to 1,600 times/minute, which is much higher than the conventional 60 to 120 times/minute, resulting in efficient production. .

(3) The width of the weft yarn is shortened, so there is no variation in dimensions.

(4) The fuel wick 8 is formed by sewing several pieces of the split fuel wick 6 through the first sewing thread 7 to form a cylindrical shape.The upper edge of the fuel wick 8 is sewn and joined at several places. However, the heat-resistant combustion wick 9 is only sewn in one place, and during long-term use, the shape of the heat-resistant combustion wick 9, which is formed into a cylindrical shape, collapses and the wick cannot be raised and lowered smoothly, and the upper end of the wick from the fire pan. exposure becomes uneven,
Furthermore, there is no possibility that the flame will be uneven.

(5) The combustion wicking core band 3 has a smaller width and less cutting width than conventional products, and can reduce the occurrence of irregularities and cut layers during cutting unlike conventional products.

(6) Even when weaving flaws, thickness unevenness, or dirt occur, it is only necessary to remove the divided fuel wick 6 in that part, so there is no loss in making the entire wick defective as in the conventional case.

(7) In order to prevent product misalignment, a number of belts are used to inspect the thickness and weave of the continuous band-shaped fuel wicking core or heat-resistant combustion core (not shown) that serves as the fuel wicking core or heat-resistant combustion core. Inspection is performed using an inspection instrument equipped with sensors at various locations, but since the fuel wicking core band 3 is narrow, there are fewer locations to install sensors, and inspections can be carried out using compact equipment, as well as automation and labor savings. It is something.

(8) The wide bending part 2 bends smoothly when moving up and down the core,
You can easily adjust the firepower.
