Description

Recycled yarn recycling winder

The present invention relates to a recycled yarn regenerated winder, and more particularly, to a recycling yarn winder that is detachably mounted around a cam roll of an existing winding device and winds dissociated recycled yarn into a spool by using the rotational force of the cam roll. will be.

Efforts to reduce greenhouse gas to preserve the global environment are being pursued by policy, led by developed countries in Europe and America, and international environmental regulations in response to climate change have expanded and evolved into economic problems, leading to national competitiveness problems.

Accordingly, global companies are very interested in eco-product production and eco-marketing in order to raise the national image and brand image by emphasizing environmental management.

In advanced countries such as Europe, the use of recycled materials is mandatory, or fabric materials using eco-friendly methods are recommended to be used after reviewing them first.

In a situation where fundamental measures are needed against the vulnerability of our economy due to the crisis of energy and resource depletion, it is time for the textile industry to enter the eco-friendly green textile industry market led by advanced countries by using green textile as a new growth engine.

Global textile companies as well as fashion brands are focusing on eco-friendly products as the preparation of countermeasures according to the environmental regulations of international organizations and the purchase of various textile products reflecting the LOHAS trend of consumers are increasing, and some domestic and foreign chemical fiber companies are By releasing recycled materials and biodegradable fibers one after another, they are entering a full-fledged competition to preoccupy the eco-friendly textile market.

On the other hand, the yarn, which is the basis of the fiber, is recycled in various ways. Representatively, in the case of a knitted fabric, the fabric that knits the fabric is unwound, and it is wound around a spool to form a regenerated yarn.

However, there is no proper means for winding the released yarn onto the spool to form the reclaimed yarn, so conventionally, the reclaimed yarn is directly wound around the spool by hand to construct the reclaimed yarn. Such manual work is not only inefficient, but also ineffective in that it cannot guarantee high productivity.

Since the recycled fabric winder (2) according to the present invention is inseparable from the bar winding device (1) that is installed and used in conjunction with the existing winding device (1), the structure of the existing winding device (1) will be briefly described below. to describe

FIG. 1 is a view showing the structure of the existing winding device 1 , and the structure of the existing winding device 1 will be described with reference to FIG. 1 .

The normal winding device 1 is a device for subdividing the manufactured yarn by winding a predetermined amount on each spool. do the work

To this end, the winding device 1 includes a main body 2 in which a driving motor 3 is built-in, a shelf 4 installed in a transverse direction from the main body 2, and a shelf 4 vertically upright in the shelf 4 to form the yarn. A support 5 for supporting the roll 6, a drive shaft 7 rotated at the top of the shelf 4 by receiving the driving force of the drive motor 3, and a cam roll installed on the path of the drive shaft 7 ( 8) and the spool is rotatably mounted in place so that the spool is in rolling contact with the cam roll 8 and includes a spool support part 9 that is rotatably installed toward the cam roll 8.

When the spool is in rolling contact with the cam roll 8 , it may be rotated in conjunction with the rotation of the cam roll 8 . In this state, the yarn unwound from the yarn roll 6 is supplied as a spool and has a configuration in which it is wound around the spool according to the rotation of the spool.

When the yarn is wound to a certain extent on the spool, as shown in FIG. 2 , the spool support part 9 is rotated downward to separate the spool from the cam roll 8 , and then the spool is removed from the spool support part 9 .

On the other hand, the recycled yarn regenerated winder (2) according to the present invention is detachably mounted on the existing winding device (1) configured as described above and separately stored recycled yarn using the rotational force of the cam roll (8) for separate recycling ( It is wound on R) to constitute a recycled yarn (regenerated yarn).

In other words, if the recycled yarn regenerated winder 2 according to the present invention is used, the structure of the existing winding device 1 can be used as it is without having to rely on manual work to wind the recycled yarn on the spool (R). Effectiveness and efficiency are ensured, and in particular, since a separate power source for rotating the spool R for recycling is not required, the structure can be greatly simplified.

Hereinafter, the recycled yarn regenerated winder 2 according to the present invention will be described based on the technical development background of the present invention described above. Prior to the detailed description, if an approximate, non-strict direction standard is specified with reference to the accompanying drawings, the reference system is divided into up and down, left and right, front and back in the state as shown in FIG. specify

Recycled yarn regenerated winder (2) (hereinafter referred to as winder (2)) according to the present invention is largely as shown in FIGS. 4 to 6, plate 10, winding unit 20, storage unit ( 30) and the guide bar 40 may be defined.

First, when the winder 2 is mounted on the winding device 1, the plate 10 may be configured as a pair with the cam roll 8 of the winding device 1 in the center and spaced apart from each other in parallel. .

Each of the pair of plates 10 may be seated on the shelf 4 of the winding device 1, and a shaft through hole 11 through which the drive shaft 7 passes may be cut toward the bottom at the lower portion, In the upper part, the shaft mounting hole 12 on which the left and right ends of the winding part 20 are mounted may be cut toward the upper part.

In particular, since the shaft mounting hole 12 is cut toward the top, the shaft mounting hole 12 itself can be made in the form of a long hole with an open top, and through this, the winding unit 20 can be easily attached to the plate 10 . In addition, as the amount of winding increases in the process in which the recycled yarn is wound on the spool (R), the recycled yarn is formed thicker around the spool (R). In this case, as shown in FIG. 7, the winding part 20 ) its upward movement is inevitable, and it becomes a structure that can elastically accommodate the upward movement of the winding unit 20 through the shaft jig 12 .

The winding unit 20 has both left and right ends rotatably mounted on the pair of plates 10 , a spool R is fixed in the center, and the fixed spool R is applied to the outer circumferential surface of the cam roll 8 . By rolling it, it is rotated without power in a direction opposite to the rotation direction of the cam roll (8).

The left and right ends of the winding unit 20 may be respectively mounted on the shaft mounting holes 12 formed in the pair of plates 10 , and in this state, the centrally mounted spool R is the cam roll 8 . When the outer circumferential surface is in rolling contact, the spool R is rotated by the rotational force of the cam roll 8 and the winding unit 20 itself is rotated in conjunction therewith.

When the recycled yarn is supplied toward the spool (R) mounted on the winding unit 20, the recycled yarn may be wound around the spool (R) by rotation of the spool (R).

That is, the winding unit 20 in this embodiment does not require a separate power source, and can be rotated by the rotational driving force of the cam roll 8 of the existing winding device 1 to wind the recycled yarn on the spool R. . Accordingly, the structure of the winder 2 itself can be greatly simplified.

The winding unit 20 may have various structures in a line that fixes the spool (R) in the center and the left and right ends can be rotatably mounted on the pair of plates 10, so detailed descriptions will be omitted below. do.

The storage unit 30 is configured in the form of a housing in which the recycled yarn in the dissociated state is stored, and may be mounted on the front surface of the pair of plates 10 . The storage unit may store the recycled yarn in a dissociated state, but the fabric itself may be accommodated and the recycled yarn may be released from the fabric.

In this case, the recycled yarn in the dissociated state refers to a yarn in the form of a long fiber released from the fabric for recycling.

An outlet 31 is formed on the upper surface of the storage unit 30 through which the recycled yarn stored therein can escape, or the entire surface of the storage unit 30 is formed in a mesh shape to allow the recycled yarn to escape into the mesh grid structure. there is.

The recycled yarn stored in the storage unit 30 in this way may be directly supplied as a spool (R), or may be supplied as a spool (R) after being guided by the guide bar 40 .

In the following description, the recycled yarn discharged from the storage unit 30 will be described based on an embodiment in which the recycled yarn is guided to the guide bar 40 and then supplied to the spool (R) side.

The upper surface of the storage unit 30 is configured to be openable and openable to accommodate the dissociated recycled yarn bundle inside.

The guide bar 40 is made in plurality, connects the pair of plates 10 and guides the recycled yarn supplied from the storage unit 30 to the winding unit 20 .

The plurality of guide bars 40 apply tension to the recycled yarn toward the winding unit 20 to assist the recycled yarn to be more strongly wound on the spool (R).

The plurality of guide bars 40 may be exemplified by a first guide bar 40a, a second guide bar 40b, and a third guide bar 40c.

First, the first guide bar 40a connects the rear upper end of each of the pair of plates 10 . At this time, a waxing unit 60 may be installed on the first guide bar 40a as shown in FIG. 8 .

The waxing unit 60 serves to apply the wax 68 to the outer surface of the recycled yarn while the recycled yarn is supplied as a spool (R).

To this end, the waxing unit 60 includes a bracket 61 mounted on the outside of the first guide bar 40a, a wax holder 62 formed on the upper portion of the bracket 61 and on which a cylindrical wax 68 is mounted, A first yarn gripping piece 63 formed on the upper portion of the bracket 61 and extending to one side of the parallel bar 64 , mounted on the parallel bar 64 to face the first yarn gripping piece 63 . The second yarn gripping piece 65 to be used, an elastic spring 66 mounted on the parallel bar 64 and elastically pressing the second yarn gripping piece 65 in the direction of the first yarn gripping piece 63, and the bracket It can be exemplified as including a wax cutter 67 that is mounted on the front of the 61 and removes the wax layer applied excessively to the recycled yarn.

The recycled yarn supplied to the waxing unit 60 passes around the wax 68 mounted on the wax holder 62 , and then passes between the first yarn holding piece 63 and the second yarn holding piece 65 .

At this time, wax may be applied to the surface of the recycled yarn, and the recycled yarn to which the wax is applied passes between the first yarn holding piece 63 and the second yarn holding piece 65, and at this time, the recycled yarn is applied to the first The yarn gripping piece 63 and the second yarn gripping piece 65 are held from both sides to prevent the recycled yarn from being separated.

In particular, since the second yarn gripping piece 65 is in a state of elastically pressing the first yarn gripping piece 63 by the elastic spring 66, the recycled yarn passing therebetween is pressed with a certain pressure and the waxing part ( 60) is prevented.

The recycled yarn passing between the first yarn gripping piece 63 and the second yarn gripping piece 65 passes through the deletion groove 67a formed in the wax cutter 67. At this time, while passing through the deletion groove 67a Excess wax can be removed.

The recycled yarn passing through the wax cutter 67 moves toward the second guide bar 40b.

The second guide bar 40b is disposed to be spaced apart from the lower portion of the first guide bar 40a. At this time, the second guide bar 40b may be provided with a disconnection detection unit 41 for detecting the breakage of the recycled yarn.

The disconnection detection unit 41 is made of a sensor that detects the presence of an object, such as an infrared sensor or an ultrasonic sensor, or when the roll moving in one direction in contact with the recycled yarn is continuously rotated by the recycled yarn and the rotation of the roll stops, it It can be configured in various ways, such as a sensor module that outputs the yarn break signal.

When the disconnection signal is output by the disconnection detecting unit 41 , it may be set to sound a warning sound or stop driving the cam roll 8 .

On the other hand, the dissociated recycled yarn is, as shown in FIG. 9, a crimp-like untwisted part (hereinafter referred to as a twist part (t) due to the non-uniformity of tension artificially or naturally generated in the process of dissociating the yarn from the fabric or in the process of using the fabric. ) is intermittently present.

If it is not possible to properly select such a twisted portion (t), the marketability of the recycled yarn is significantly reduced.

Therefore, in this embodiment, it is possible to sort out the twisted portion (t) included in the recycled yarn, and has a structure that prevents the twisted portion (t) from being wound on the spool (R).

To this end, the third guide bar 40c connects the front of each of the pair of plates 10, and the recycled yarn toward the winding portion 20 is passed through the center of the twisted portion (t) of the recycled yarn. A bushing member 42 is formed to restrict passage.

In addition, the bushing member 42 may also serve to limit the passage of the fabric when the fabric itself is pulled from the storage unit 30 .

The recycled yarn discharged from the storage unit 30 first passes through the bushing member 42 of the third guide bar 40c. At this time, the twisted portion t has a structure that prevents it from passing.

A first through hole 43 through which the recycled yarn passes into the bushing member 42 may be formed through in front and rear directions, and a twisted portion ( When t) meets the bushing member 42 , the twisted portion t has a structure that does not completely pass through the first through hole 43 .

Since the twisted portion t exists in an expanded state in volume than the normal recycled yarn, when the diameter of the first through hole 43 is formed at a line through which only the recycled yarn can pass, the bushing member 42 is naturally twisted. It becomes possible to restrict the passage of (t).

If necessary, when the twisted part t is supplied to the bushing member 42 side, the driving of the cam roll 8 is automatically stopped and the user removes the twisted part t and then the recycling operation can be resumed. .

To this end, as shown in FIG. 10 , when the twisted portion t of the recycled yarn passes through the bushing member 42 , a sensing means 50 for generating a sensing signal may be installed.

When the detection signal is generated, a separate control unit controls the driving of the driving motor 3 to stop the rotation of the cam roll 8 . Accordingly, the rotation of the winding unit 20 may also be stopped.

The detection means 50 has the following structure to detect only the twisted portion t in the recycled yarn.

As an example, the sensing means 50 is installed so as to reciprocate in the forward and backward directions in the first through hole 43 as shown in FIG. 10 and has a second through hole 55 through which the recycled yarn passes in the center. An operating ring 51 formed through, an elastic member 52 that elastically presses the operation ring 51 forward in the first through hole 43 , and fixedly installed at the rear end of the first through hole 43 . It is installed on the rear surface of the first electrode 53 and the actuating ring 51 facing the first electrode 53, and when the actuating ring 51 is pulled rearward by the movement of the twisted portion t of the recycled yarn, the second It may be exemplified as including the second electrode 54 forming a contact point with the first electrode 53 .

As shown in FIG. 11a, the actuating ring 51 dl elastically pressed forward by the elastic member 52 in the first through hole 43 is a twisted part moving from the front to the rear of the first through hole 43 ( t), as shown in FIG. 11B , the first electrode 53 and the second electrode 54 come into contact to form a contact point.

At least one of the first electrode 53 and the second electrode 54 may be electrically connected to the control unit, so that a sensing signal according to the generation of the contact may be transmitted to the control unit. The control unit may stop the driving of the driving motor 3 based on this detection signal.

When the first electrode 53 and the second electrode 54 are in contact with each other to form a contact point, various known structures may be referred to from a line capable of transmitting a specific signal to the control unit, and thus detailed descriptions thereof will be omitted.

That is, when a contact point is generated between the first electrode 53 and the second electrode 54 , the detection signal is generated, and the driving of the cam roll 8 can be controlled based on the detection signal.

Meanwhile, the storage unit 30 is detachably mounted on the plate 10 as shown in FIG. 12 , and may be configured to adjust the upper and lower heights.

To this end, on the front surface of the plate 10, a hanger 13 in which a 'L'-shaped hanging groove 14 is continuously formed in an up and down direction is provided, and on the rear surface of the storage unit 30, the hanging groove ( 14) may be formed with a hook 32 that is supported by the hook.

That is, when the hanger 13 is hung on the hanger groove 14 formed at a required height, the relative height of the storage unit 30 can be easily adjusted.

The reason for configuring to adjust the height of the storage unit 30 is to adjust the height of the storage unit 30 in proportion to the consumption of recycled yarn stored in the storage unit 30 .

If the storage unit 30 is in a state where most of the recycled yarn is consumed, the recycled yarn is released from the bottom surface of the storage unit 30 and thus the recycled yarn is released from the storage unit 30 to the third guide bar 40c. As the length becomes longer, the recycled yarn may become twisted.

That is, if the recycled yarn in the storage unit 30 is consumed, moving the storage unit 30 to the upper position is preferable in terms of not forming the length of the recycled yarn unnecessarily long.

The embodiments of the present invention described above are merely exemplary, and those of ordinary skill in the art to which the present invention pertains will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, it will be well understood that the present invention is not limited to the form mentioned in the above detailed description. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims. Moreover, it is to be understood that the present invention covers all modifications, equivalents and substitutions falling within the spirit and scope of the invention as defined by the appended claims.
