Spoon is used to clean cooking utensils and dishes in a restaurant or home. One type of scrubbing brush is shown in Fig. The scrubbing brush shown in Fig. 1 is composed of a mixed knitting section in which a metal rolled yarn and a synthetic yarn are simultaneously knitted into an annular shape, and a synthetic knitting section in which the synthetic resin is knitted into an annular shape. The sponge is contained in the wool cloth, and the synthetic knitting section is sealed by thermal bonding using ultrasonic waves or the like. If the knitted fabric is thermally adhered to the knitted fabric, breakage or the like of the thermal bonding tool may occur. Therefore, a synthetic knitting section is necessarily required for thermal bonding.

The above-described scrubbing brush is manufactured by a water-repellent annular knitting machine. A disposable woven circular knitting machine is a machine for manufacturing a woven cloth for a woven cloth in which an annular mixed knitting section of a loofah and an annular synthetic knitting section are continuously formed. The sponge is introduced into the manufactured woolen cloth, and then the woolen fabric is finished by thermally adhering and cutting the circular synthetic knitting section.

When a woolen fabric is manufactured by a woolen circular knitting machine, not only a synthetic yarn winding failure is provided in a woolen circular knitting machine, but a metal rolled yarn winding failure is provided in a woolen knitting machine so that the synthetic yarn and the metal rolled yarn are fed to the circular knitting machine. At this time, the synthetic yarn is not easily broken because of its strong tensile strength. However, since the metal rolled yarn has a weak tensile strength and is easily broken due to its low tensile strength, the productivity is lowered and the defect rate of the product is also increased. Particularly, the metal rolled sheet is caught in the edge portion of the failure, and the metal rolled sheet having a weak elasticity and tensile force is frequently disconnected. Such disconnection of the metal rolled sheet not only causes the defect of the product but also delays the production, which causes the productivity to be remarkably deteriorated.

Patent Publication No. 1994-0008078 (published on Mar. 9, 1994) discloses a rolling yarn feeder and a fabric take-off device for a loofah knitting machine. SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a rolled yarn supply unit specifically designed to smoothly supply and cut off rolled yarn so that the rolled yarn supplied during knitting is not cut off.

The Utility Model No. 1994-0001738 (published on Mar. 24, 1994) discloses a yarn breaker of a loofah loom. The disclosed apparatus is devised to solve the above-mentioned problems, and prevents the yarn supplied by the yarn supplying interrupter from being broken or entangled.

Patent Registration No. 10-1614459 (Registered on May 14, 2016) discloses an annular knitting machine for making a loofah circular knitted fabric having an improved circular knitted structure. The disclosed apparatus improves the supply of the cleaning yarn to prevent the cleaning yarn of the plate-like cleaning yarn from being cut during the elevation of the cleaning yarn and in the feeding process, thereby enabling continuous knitting of the circular knitted fabric. On the other hand, Patent Registration No. 10-1714488 (registered on Mar. 03, 03, 2013) discloses a method of manufacturing a detergent and a detergent having improved cleaning power.

The above-mentioned conventional techniques have an advantage in that the metal rolled yarn supplied from the circular knitting machine for manufacturing a circular knitted woven fabric is prevented from being broken during the knitting process, but the metal rolled yarn supplying portion has to be complicatedly configured.

Therefore, it is an object of the present invention to eliminate the need for complicated construction of the metal rolled yarn supply portion because the rolling mill for producing the rolled metal yarn is interlocked with the annular knitting machine for producing the rolled knitted fabric, An object of the present invention is to provide an annular knitting machine for manufacturing a scarlet knot type knitted fabric capable of preventing the metal rolled yarn fed during knitting of a wool ball from being cut off, thereby improving the productivity at the time of manufacturing the wool knotted circular knitted fabric and greatly reducing the defective ratio.

In order to accomplish the above object, the present invention provides an annular knitting machine for manufacturing a woolen annular knit fabric, comprising: a metal rolled yarn supply part for supplying a metal rolled yarn; a synthetic yarn made of synthetic resin or a synthetic yarn made of natural yarn; An annular circular knitting portion using the metal rolled yarn and the synthetic yarn at the same time or knitting with an annular knitted fabric using only the synthetic yarn, a driving portion for driving the annular knitted portion, and a control portion for controlling the driving portion.

Wherein the metal rolled yarn supply unit includes a metal wire supply unit for supplying a metal wire having a circular sectional area and a pair of compression rollers for forming a metal rolled yarn by passing the metal wire supplied from the metal wire supply unit, The metal rolled yarn formed by the pair of squeeze rollers is directly supplied to the annular circular knitting portion from the squeeze roller.

And the operation of the squeeze roller of the metal rolled sheet supply part is controlled by the control part.

The control unit synchronizes the rotation of the pressing roller and the rotation of the driving unit.

Wherein the metal wire supply unit is composed of a failure part in which the metal wire is wound and the failure part is arranged in a fixed state without rotating to allow the metal wire to be released vertically and a guide roller is disposed vertically above the failure part , And the metal wire is fed from the failure portion to the squeeze roller through the guide roller.

And the metal rolled yarn fed from the pressing roller is elastically guided by the elastic guide portion and fed to the circular knitting portion.

Hereinafter, the present invention will be described in detail with reference to the drawings.

2 to 4, an annular knitting machine 10 for manufacturing a woolen annular knitted fabric according to the present invention includes a metal rolling yarn supply unit 100 for supplying a metal rolled yarn 122, a synthetic yarn 212 Or synthetic yarn 212 using only the synthetic yarn 212 or the synthesized yarn 212 supplied from the synthetic yarn supply unit 200 supplying natural yarns made of natural raw materials, A driving part 400 for driving the circular knitting part 300, a control part 500 for controlling the driving part 400 and a woolen fabric 310 knitted in the circular knitting part 300 are taken out from the circular knitting part 300, And a woolen fabric recovery unit 700 for recovering and collecting the woolen fabric 310 drawn by the woolen fabric take-out unit 600 and the woolen fabric take-out unit 600. Here, the circular knitting portion 300, the driving portion 400, the woolen fabric take-out portion 600, and the woolen fabric collecting portion 700 can be constructed and operated in the same manner as applied to the prior art. Therefore, the components described in the above-mentioned prior art will be referred to and detailed description will be omitted.

Generally, when a wringing cloth is manufactured by a wringer annular knitting machine, not only a synthetic yarn winding failure is installed in a wicking circular knitting machine, but a failure in winding a metal rolling yarn is installed in a wicking circular knitting machine to supply a synthetic yarn and a metal rolling yarn to an annular knitting machine . At this time, the synthetic yarn is not easily broken because of its strong tensile strength. However, since the metal rolled yarn has a weak tensile strength and is easily broken due to its low tensile strength, the productivity is lowered and the defect rate of the product is also increased. Particularly, the metal rolled sheet is caught in the edge portion of the failure, and the metal rolled sheet having a weak elasticity and tensile force is frequently disconnected. Such disconnection of the metal rolled sheet not only causes the defect of the product but also delays the production, which causes the productivity to be remarkably deteriorated.

In the above-mentioned prior art, the metal wire is rolled by a rolling machine to produce a metal rolled yarn, and the rolled metal rolled yarn is continuously wound to fail to complete the rolling process. The yarn supplying unit is rotatably installed in the annular knitting machine. In such a conventional technique, the metal rolled yarn having a relatively low tensile strength is broken during the knitting process and the operation is likely to be interrupted, so that the metal rolled yarn supply portion is specifically configured to prevent the above-described problem.

On the contrary, a feature of the present invention is that the rolling mill 100 for manufacturing the rolled metal sheet 122 is not made complicated, but the rolled knitting machine 10 for producing a rolled loose knit fabric is made of metal rolling It is not necessary to use the failure of winding the metal rolled yarn 122 on the annular knitting machine 10 by interlocking with the yarn supplying section 100 so that it is not necessary to make the metal rolled yarn supply section 100 complicated. In addition, by preventing the metal rolled yarn 122 supplied during the circular knitting of the wool ball from being broken, the productivity of the wool ball circular knitted fabric can be improved and the defective ratio of the wool ball circular knitted fabric manufactured can be greatly reduced.

Specifically, in the annular knitting machine 10 of the present invention, the metal roll feeder 100 includes a metal wire feeder 110, a pair of squeeze rollers 120, and a motor 130.

The metal wire feeder 110 supplies a metal wire 112 having a circular cross-sectional area, in particular, a metal wire made of stainless steel, and the metal wire 112 is wound. At this time, the failure 110 is arranged in a fixed state without rotating, and the metal wire 112 is released in an upwardly upward direction.

A guide roller 140 is disposed vertically above the failure 110 to allow the metal wire 112 to be released from the failure 110 vertically upwardly. Thus, the metal wire 112 is fed to the squeeze roller 120 via the guide rollers 140 at failure 110.

Although not shown in the drawing, the upper rim portion of the failure 110 is double-plied to allow the metal wire 112 to be released vertically upwardly from the failure 110 without hitting the upper rim of the rupture 110 And a valley is formed between the upper and lower edges of the double-sided rim, and the resilient guide portion can be rotatably installed in the thus formed valley. The elastic guide portion extends outward beyond the rim of the failure 110 to prevent the metal wire 112 from being caught in the rim of the failure 110 when the metal wire 112 is released from the failure 110.

The pair of squeeze rollers 120 pass the metal wire 112 and press it to make the metal rolled yarn 122. The metal rolled yarn 122 formed by the squeeze roller 120 is directly supplied from the squeeze roller 120 to the circular knitting section 300.

The motor 130 drives the pressing roller 120. The squeeze roller 120 may be composed of a drive roller and a driven roller. The driving force of the motor 130 is transmitted to the driving roller of the pressing roller 120 by the belt 132. The driving force of the driving roller is transmitted to the driven roller by gear engagement, can do. At this time, the drive roller and the driven roller rotate in opposite directions.

This configuration of the metal rolled sheet supply portion 100 is substantially the same as the above-mentioned rolling machine that rolls the metal wire 112 to the metal rolled yarn 122. However, And the metal rolled yarn 122 is wound around the metal rolled yarn 122 in a failure.

The present invention does not adopt a method of winding a metal rolled sheet by failing, thereby preventing a problem caused by failure of rolling the rolled metal sheet. More specifically, when the rolled metal rolled sheet is fed by fail, the rolled sheet metal is caught in the edge portion of the rolled sheet. Therefore, the rolled rolled sheet having a low elasticity and tensile strength is frequently disconnected, This disconnection of the company not only causes the defect of the product but also causes the production delay, thereby remarkably reducing the productivity. The present invention relates to a method of manufacturing a rolled knitting machine for manufacturing a rolled knit fabric by interlocking a rolling mill 100 for manufacturing a rolled metal sheet 122 as a rolled metal sheet feeder 100 This problem can be prevented.

The metal rolled yarn 122 supplied from the pressing roller 120 to the annular circular knitting section 300 in the metal rolling yarn supplying section 100 is elastically guided by the elastic guide section 150 to be guided to the annular circular knitting section 300 . The elastic guide portion 150 is formed of a straight or curved rod that is elastically deformed by itself, and a hole through which the metal rolling yarn passes is formed at the end of the rod. The elastic guide portion 150 may further include a traction spring to further supplement the elastic deformation. The elastic guide unit 150 is installed on the base 320 on which the circular knitting unit 300 is installed. To this end, a support base 330 is installed on the base 320. That is, the elastic guide unit 150 is installed on the support base 330.

The synthetic yarn supply unit 200 includes a failure unit 210, a synthetic yarn 212, a fixed guide unit 220, and an elastic guide unit 230. The failure portion 210 is installed on the base 320. A synthetic yarn 212 is wound around the failure portion 210. The synthetic yarn 212 wrapped around the failure portion 210 is released to the upper portion of the failure portion 210 without rotating the failure portion 210 and is guided by the fixed guide portion 220 and the elastic guide portion 230, And is supplied to the knitting portion 300. At this time, the fixed guide unit 220 is formed as a fixed body having a loop in which the synthetic yarn 212 is inserted, and the elastic guide unit 230 is configured to be elastically deformed as mentioned above, 220 and the elastic guide portion 230 are installed on the support base 330.

5 is a diagram illustrating a control system according to an embodiment of the present invention. As shown in FIG. 5, in the present invention, the control unit 500 controls the driving unit 400 and the motor 130 at the same time. The rotational force of the driving unit 400 is transmitted to the annular circular knitting unit 300 and the woolen fabric take-off unit 600. The rotational force of the motor 130 is transmitted to the pressing roller 120. The control unit 500 simultaneously controls the operation of the annular circular knitting unit 300 and the operation of the pressing roller 120 and the rotation of the driving unit 400 and the circular knitting unit 300 and the rotation of the pressing roller 120 Synchronize.

The control unit 500 simultaneously controls the driving unit 400 and the motor 130 so that the rotation of the driving unit 400 and the motor 130 is synchronized when the circular knitting unit 300 knits a mixed knitting section of the woven circular knitted fabric 310 So that the metal rolled yarn 122 and the synthetic yarn 212 are supplied to the circular knitting portion 300 at the same time. The motor 130 and the pressing roller 120 are operated under the control of the control unit 500 so that the metal wire 112 is pressed by the pressing roller 120, Is rolled with the metal rolled yarn 122 and then the rolled metal yarn 122 is supplied to the circular knitted fabric 300 together with the synthetic yarn 212. [

On the other hand, the control unit 500 controls the rotation of the motor 130 to stop when the circular knitting machine 300 knits the synthetic knitting section of the circular knitted fabric 310. Then, the operation of the pressing roller 120 is stopped, and as a result, the supply of the metal rolled yarn 122 to the annular circular portion 300 is stopped. The control unit 500 controls the driving unit 400 to continuously operate so that only the synthetic yarn 212 is supplied to the circular knitting unit 300 by the rotation of the driving unit 400 alone.

6 is a diagram illustrating a control system according to another embodiment of the present invention. The embodiment of FIG. 6 differs from that of FIG. 5 in that the controller 500 is formed of two. The first control unit 510 controls only the driving unit 400 and the second control unit 520 controls the motor 130 only. The first control unit 510 and the second control unit 520 can communicate with each other through wired / wireless communication so that the rotation of the driving unit 400 and the rotation of the motor 130 can be synchronized. The first control unit 510 may be installed in the main body of the circular knitting machine 10 and the second control unit 520 may be installed in the metal rolled sheet supply unit 100.
