Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a dual drive unit for a hook and loop fastener producing knitting apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knitting machine for knitting a hook or a loop in a strip of a hook and a loop fastener called a Velcro tape and more particularly to a knitting machine in which a weft guide bar of a knitting machine is composed of dual yarns, To a weft guide bar dual drive device of a knitting machine for hook and loop fasteners which can increase the density of hooks or loops on a strip of the same area so that the function of the fastener is weakened early or the lifetime is shortened will be.

Touch fasteners (commercially known as Velcro, Scotchmate, Tri-Hook, etc.) were originally made using textile technology. The two most common types of touch fasteners are hook and loop fasteners and mushroom and loop fasteners.

The hook loop fastener can be composed of a pair of fabric strips. The fabric strips can be matched (matched) to form a recycling closure. Wherein one of the matches is a strip of fabric fabric having a plurality of monofilament elements shaped like a hook projecting from one surface and the other of the matches is a multifilament woven with loop- ≪ / RTI > When the mating surfaces of the strips are pressed together, the plurality of hook elements on the strip snare the loop elements on opposing strips and create a temporary, reusable bond. Since the strips are separately peeled, the hook element is deformed and separated from the loop element, making it possible to reuse the fastener several times.

In the case of mushroom-shaped and loop fasteners, the hook-shaped mating strip is replaced by a strip containing numerous single-strand protrusions with mushroom-shaped heads. The mushroom-shaped head is formed by a bulbous "mushroom-shaped head" When the strip is peeled off separately, the mushroom-shaped member is warped as a whole and loosens the loop member, but the mushroom-shaped head is often broken, however, Thereby reducing the number of times the fastener can be reused.

Very recently, thermoplastic extrusion / molding methods for making touch fasteners have received much attention. In the case of hook and loop fasteners, the loop strip may be produced using weaving, knitting or nonwoven techniques, while the hook strip may still be extrusion / molding. In the case of mushroom and loop fasteners, Can be produced by extrusion molding / molding a strip of material having pin-like protrusions and then post-forming a round flat mushroom-like head over pin-like protrusions; Loop strips are still produced using weaving, knitting or nonwoven technology.

As described above, in the case of hook and loop fasteners, since they are manufactured by weaving and knitting, a knitting operation is required in the manufacturing process, and the knitting operation is performed by a knitting machine. However, according to the conventional knitting machine, the hooks or loops are not densely packed so that the hooks or the loops are widened as shown in the photograph of Fig. 1 (see Fig. 1), the function of the fasteners is weakened, .

A drive belt gear unit (not shown) is disposed on a central portion of the drive shaft 110 to be spaced apart from the gear unit by a predetermined distance. Here, the drive belt gear portion is disposed in the inner region of the mounting portion 11.

The driven shaft 120 is rotatably disposed on the driving shaft 110 of the knitting machine body 10 and rotates in conjunction with the driving shaft 110. The driven shaft 120 has a belt gear portion And is connected to the drive belt gear portion of the drive shaft 110 as a belt. Accordingly, as the drive shaft 110 rotates, the driven shaft 120 rotates in conjunction.

The first and second rotary plates 131 and 132 are coupled to both ends of the driven shaft 120 and rotated together with the driven shaft. The first and second rotary plates 131 and 132 are formed with a plurality of long holes at the central portion thereof, and are passed through the bolts to be fastened to the follower shaft 120.

One end of the first crank bar 141 is eccentrically connected to a portion deviated from the center of the first rotating plate 131. As the first rotating plate 131 rotates, one end of the first crank bar 141 is eccentrically rotated, do.

The lower end of the first lever 151 is coupled to one end of the fixed shaft 13 provided at the lower end of the mounting portion 11 of the knitting machine body 10 and the lower end of the first lever 151 is connected to the lower end of the first crank bar 141 The upper end is repeatedly rotated in the left and right direction of the knitting machine about the lower end in accordance with the crank motion of the first crank bar 141. [

One end of the first joint bar 161 is coupled to the upper end of the first lever 151. One end of the first joint bar 161 may be in the form of an eye bolt, and the eye bolt and the first lever 151 may be coupled by a joining member. In this case, a long hole is formed at the coupling portion of the first lever 151 with the coupling member, so that the coupling position can be adjusted within the length of the long hole.

The first weft guide bar unit 171 includes a guide bar block 171a coupled to the other end of the first joint bar 161 and a pair of guide bars 171b vertically coupled to the guide bar block Lt; / RTI > Here, the guide bar 171b reciprocates linearly in the lateral direction of the knitting machine body 10 by the cooperation of the first crank bar 141, the first lever 151 and the first joint bar 161 Weaving will be done. Meanwhile, the guide bar 171b may be provided so as to extend in the width direction of the knitting machine, and the end thereof may pass through a guide (not shown) provided in the knitting machine main body. Therefore, smooth linear reciprocating motion of the guide bar 171b becomes possible.

One end of the second crank bar 142 is eccentrically connected to a portion deviated from the center of the first rotating plate 131. As the first rotating plate 131 rotates, one end of the second crank bar 142 is eccentrically rotated, do. However, the second crank bar 142 is installed so as to have a phase difference with respect to the first crank bar 141 in the circumferential direction.

The lower end of the second lever 152 is coupled to the other end of the fixed shaft 13 provided at the lower end of the mounting portion 11 of the knitting machine body 10 and the lower end of the second lever 152 is connected to the lower end of the second crank bar 142 So that the upper end is repeatedly rotated in the left and right direction of the knitting machine about the lower end in accordance with the crank motion of the second crank bar 142. [ In this case, since the first and second crank bars 141 and 142 are provided with a phase difference from each other, for example, when the first lever 151 rotates clockwise, the second lever 152 rotates counterclockwise, An operation is performed.

The second joint bar 162 is coupled to the upper end of the second lever 152 at one end. One end of the second joint bar 162 may be in the form of an eye bolt. Here, a long hole is formed at the joint portion of the second joint bar 162 of the second lever 152, so that the engagement position can be adjusted within the length of the long hole.

The second weft guide bar unit 172 includes a guide bar block 172a coupled to the other end of the second joint bar 162 and a pair of guide bars 172b vertically coupled to the guide bar block Lt; / RTI > Here, the guide bar 172b linearly reciprocates in the left-right direction of the knitting machine body 10 by the cooperation of the second crank bar 142, the second lever 152 and the second joint bar 162 Weaving will be done. On the other hand, the guide bar 172b is installed so as to extend in the width direction of the knitting machine, and the end of the guide bar 172b can be installed to pass through a guide (not shown) provided in the knitting machine main body. Therefore, smooth linear reciprocating movement of the guide bar 172b becomes possible.

The pair of guide bars 171b of the first weft guide bar unit 171 are supported so as to pass through the first end block 181 provided on one side and the other side of the knitting machine body 10 Allow horizontal reciprocating motion.

The pair of guide bars 172b of the second weft guide bar unit 172 are supported so as to pass through the second end block 182 coupled to the upper side of each of the first end blocks 181, It is possible to horizontally reciprocate on the upper side of the guide bar 171b of the first weft guide bar unit 171.

According to this configuration, by supplying the wefts alternately, it is possible to increase the density of hooks or loops in the fastener straps as shown in the photograph of FIG.

On the other hand, since the guide bars 171b and 172b are reciprocating parts, the guide bars 171b and 172b may be coated as follows to enhance the hardness.

That is, the metal base material of the guide bar is subjected to a heat treatment at a temperature of 500 to 650 占 폚 with a nitriding gas composed of nitrogen gas, ammonia gas or a mixture gas thereof to nitridize the surface of the base material. The nitrided metal base material is charged into a rotatable chamber, a mixture of a metal halide catalyst and a metal powder is charged into the chamber, the temperature inside the chamber is raised to 800 to 1100 ° C, and the chamber is rotated and reacted A metal nitride is deposited on the surface of the base material for coating.

The nitriding treatment is a step of heat-treating the metal base material with a nitriding gas composed of nitrogen gas, ammonia gas or a mixture gas thereof at a temperature of 500 to 650 ° C, Thereby forming a nitrided layer of Fe 2 to 3 N (ε-phase) on the outermost surface.

Therefore, by nitriding, only the nitrogen is penetrated and diffused to the surface of the metal base material to cause a dipping action, whereby the surface of the metal base material can be modified by imparting abrasion resistance or endothelial property while hardly changing dimensions before and after the heat treatment Thereby realizing a substantial surface treatment.

At this time, it is preferable that the nitriding treatment time is 1 to 20 hours, and the thickness of the nitrided nitride layer is set to about 2 to 50 mu m.

The nitriding treatment may be carried out continuously, in a fluidized bed, in a pit-shaped furnace or in an all-in-one furnace (sealed quench furnace). Preferably, a job of removing foreign matter formed on the surface of the nitrided metal base material can be further performed. A method of jetting high-pressure water onto the surface of the base material to remove surface oxides and foreign substances, and the like can be used.

Next, in the coating operation, the nitrided metal base material is charged into a rotatable chamber, a mixture of a metal halide catalyst and a metal powder is charged into the chamber, the inside of the chamber is heated to 800 to 1100 ° C And coating and depositing a metal nitride on the surface of the base material by rotating and reacting the chamber. Such a coating operation forms a metal nitride coating layer having a high hardness on the surface of the metal base material. By rotating the chamber using the rotatable chamber in the coating operation, the contact between the metal part and the raw material powder can be made more uniform, so that a more homogeneous coating layer can be produced.

More specifically, the reaction for forming the metal nitride coating layer will be described as follows.

First, the ammonia gas is decomposed in the above-mentioned nitriding process and activated nitrogen is diffused into the metal part base material to form nitride layers Fe 2 to 3 N (ε phase) and Fe 4 N (γ 'phase) .

2NH 3 ↔ 3H 2 + 2 [N]

Next, the metal halide catalyst and the metal powder react with the metal part base material in a protective gas atmosphere to form a metal nitride coating layer in the chamber. The reaction can be expressed as:

FeV + Cl 2 ⇒ VCl 2 + Fe,

VCl 2 + V + [N] = VN + Cl 2 ,

FeNb + Cl 2 ⇒ NbCl 2 + Nb

NbCl 2 + Nb + [N] ⇒ NbN + Cl 2

That is, the metal powder reacts with the metal base material together with the catalytic action of the metal halide catalyst to form fine and rigid nitrides such as FeN, NbN, CrN, and VN on the surface of the metal part, thereby enabling high hardness surface coating.

In this case, the reaction time for depositing the metal nitride on the surface of the base material in the coating step is preferably 3 to 9 hours. When the reaction time is shorter than the reaction time, the deposition is less likely to occur. On the other hand, when the reaction time exceeds the reaction time, the hardness of the surface and the thickness of the nitrided coating layer are decreased.

In the present invention, the metal halide catalyst and the metal powder are preferably added in a weight ratio of 1: 1-5.

In addition, the metal halide catalyst and the metal powder may include the same metal as the metal forming the metal base material. As described above, since the metal halide catalyst is reacted with the nitrogen gas to form the metal nitride coating layer, a stronger nitrided coating layer can be formed by including the same kind of metal. Preferably, the metal powder is one kind of metal powder selected from the group consisting of Fe, Nb, Cr and V, or two or more kinds of alloy powders. More preferably FeV or FeNb.

Further, the metal halide catalyst is characterized in that it is composed of any one or more metal selected from among Fe, Nb, Cr and V and any halogen element selected from F, Cl, Br and I. More preferably, chlorides, especially FeCl 2, are used as catalysts, and ammonium chloride, niobium chloride and vanadium chloride are also particularly useful forms.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. It will be understood that various changes and modifications may be made without departing from the scope of the present invention.
