Description

{Manufacturing equipment of net}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net making apparatus and, more particularly, to a net making apparatus capable of manufacturing a net in a designed form without a twisted or deformed net.

Generally, a net manufacturing apparatus for manufacturing a net is composed of a loom for knitting a rubber yarn or a synthetic resin yarn to produce a net, and a plurality of bobbins for providing rubber yarn or synthetic yarn to the loom.

In order to weave a net in a loom, a lot of yarn must be supplied to one loom. In order to supply yarn to a loom, many bobbins are arranged on one side of the loom so that the yarn is supplied from the bobbin to the loom.

In the weaving machine, the weaving is performed while pulling the yarn, and the yarn is unwound from the bobbin and transferred to the weaving machine by the bobbin being rotated by the force of the weaving machine pulling the yarn.

When a yarn is fed to a loom from many bobbins, a different tensile force acts on the yarn fed from the bobbin located at the center of the bobbin to the loom and the yarn fed from the outermost bobbin.

A larger tensile force acts on the yarn unwound from the bobbin located at the outermost side than the tensile force acting on the yarn unwound from the bobbin located at the center portion, so that the yarn unwound from the outermost bobbin is elastically deformed by a predetermined amount.

Using a yarn with different tensile force, the net woven in the loom has a problem that the yarn of a specific part is elastically restored and the net shape is twisted or twisted.

Particularly, the conventional net manufacturing apparatus has a problem that the quality of the woven net is deteriorated because the diamond shape formed between the yarn and the yarn of the woven net is not formed uniformly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the present invention and the accompanying drawings, wherein like reference numerals refer to like elements.

It is to be understood that when an element is referred to as being "comprising " another element in the specification or claims, it is not to be construed as being limited to only that element, And the like.

Generally, on the back side of passenger cars, buses, trains and aircraft seats, a net 10 made of synthetic fibers and rubber yarn is installed to conveniently store passengers' belongings.

The present invention relates to a net making apparatus for weaving such a net 10. The present invention relates to a net making apparatus for weaving a net 10, And a deck 120 installed on both sides or both sides to supply yarn to the weaving machine 110.

The deck 120 is a device for feeding a yarn wound on each of the rolls 124 to a weaving machine through a plurality of rolls 124. The deck 120 includes a front frame 122 on the side of the loom, And a rear frame 121 spaced apart by a predetermined distance.

A plurality of roll supports 123 are formed on the rear frame 121 in the form of bars protruding in the horizontal direction and a tension regulating part 123 for regulating the tension of the yarn loosely fed from the rolls 124 is provided on the front frame 122 130 are installed.

The roll 124 is formed by winding a synthetic resin or rubber yarn around a cylindrical body and inserting and fixing the roll 124 into a roll support 123 horizontally projecting from the rear frame 121 as shown in FIG. The yarn wound on the roll 124 is unwound and fed to the loom 110 by pulling the yarn wound on each roll 124 as it is woven.

The tension adjusting unit 130 is installed on the front frame 122 of the deck 120.

3 and 4, the base 131 is fastened to the front frame 122 in the form of a flat plate, and the tension adjusting portion 130 is fastened and fixed to both ends of the base 131, respectively.

5, a plate-shaped body 132 is formed and the body 132 extends upward and rearward of the body 132 to form a folded shape. And an incidence hole 133 and an exit hole 134 in the form of a hole into which the yarn is inserted are formed in the upwardly bent portion.

A fixing pin 138 protrudes upward from one side of the body 132 and a lower pressing plate 135 and an upper pressing plate 136 are inserted and fastened to the fixing pin 138.

The lower pressing plate 135 and the upper pressing plate 136 are formed with holes 135a and 136a at the center thereof and the fixing pins 138 are inserted and fixed to the holes 135a and 136a.

The upper pressure plate 136 is formed into a dish shape, and the lower pressure plate 135 is formed into an inverted dish shape.

4, the yarn of the roll 124 is inserted through the incident opening 133 of the tension adjusting unit 30 and is inserted between the lower pressing plate 136 and the lower pressing plate 135 And is moved to the supporter 125, which will be described later, through the emergence port 137. [0064]

Since the yarn is moved between the upper pressing plate 136 and the lower pressing plate 135, the yarn is pressed by the load of the upper pressing plate 136, so that the tension of the yarn supplied to the loom 110 is kept constant. do.

In order to impart additional tension to the yarn fed to the loom 110, a weight 137 having a hole through which the fixing pin 138 is inserted in the center is inserted into the fixing pin 138 as shown in FIG. 5, 137 may be added to the upper pressure plate 136. [

It is also possible to load a weight in the form of a lump in an upper platen 136 formed in a dish shape so that a load is applied to the upper platen 136 regardless of the form.

The yarn wound on the roll 124 is supplied to the supporter 125 positioned above the deck 120 in a state where the tension is kept constant through the tension adjusting unit 130. [

2 and 3, the supporter 125 having a plurality of holes 126 is installed on the upper part of the deck 120 and is released from each roll 124 And determines the movement path of the yarn such that the yarn is inserted into the hole 126 of the supporter 125 and supplied to the loom 110.

The deck 120 is formed to have a height as high as a large number of yarns are required when the net 10 is woven by the loom 110. The yarn loosened by each of the rolls 124 installed on the deck 120 is wound on the deck 120 And the yarn is fed to the upper portion of the loom 110 through which the yarn flows in the loom 110.

2, a supporter 127 for connecting the upper portion of the deck 120 on both sides of the loom 110 is formed, and a supporter 127 corresponding to the upper position of the loom 110 is formed in a shape similar to the supporter 125, So that the yarn traveling through the supporter 125 is supplied to the upper portion of the loom 110 through the collector 128.

A predetermined number of tension adjusting rollers 112 are installed on the upper portion of the loom 110 to keep the tension of the yarn fed from the collector 128 constant. As described above, a pair of tension adjusting rollers 112 that are in contact with each other are configured to wind the yarn in a zigzag form and supply the yarn to the loom 110 so that the tension of the yarn is always kept constant.

At this time, the bristles 113 are formed on the outer surface of the tension adjusting roller 112 in a short, short shape as shown in FIG. 6, thereby preventing the yarn wound on the tension adjusting roller 112 from slipping sideways, It is preferable to be configured to prevent twisting.

The deck 120 having the plurality of rolls 124 is installed on both sides of the loom 110 and the yarn unwound from the roll 124 is wound on the tension adjusting unit 130 of the deck 120 in a primary tension And the yarn moved to the upper portion of the loom 110 through the supporter 125 and the collector 128 is tensioned by the tensioner roller 112 installed on the upper portion of the loom 110, So that the netted yarn 10 is produced in a designed form without twisting or twisting.

Since the loom 110 is a well-known technique, a description of the process of weaving a yarn into the net 10 is omitted.

The technical idea of the present invention has been described above with reference to the embodiments.

It will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described above from the description of the present invention.

Further, although not explicitly shown or described, those skilled in the art can make various modifications including the technical idea of the present invention from the description of the present invention Which is still within the scope of the present invention.
