Description

REMNANTS PROCESSING UNIT FOR DYEING BOBBIN

Technical Field

[1] The present invention relates to a remnants processing unit for dyeing a bobbin, and more particularly, to a remnants processing unit for dyeing a bobbin, which includes: a plurality of guide bars respectively having an arc-shaped section; an auxiliary guide bar having an arc-shaped section, the auxiliary guide bar being disposed in a line that the auxiliary guide bar vertically gets in contact with any one of the plural guide bars and fixed to the guide bar through welding; a slit formed between the guide bar and the auxiliary guide bar in such a way that the blade is inserted into the slit to thereby guide the blade; and indication portions respectively formed on outer circumferential surfaces of upper and lower ring covers in such a way as to be located in a straight line with the slit formed between the guide bar and the auxiliary guide bar, so that the blade can be exactly located in the slit when remnants are processed from the bobbin. Background Art

[2] In general, in order to dye yarn, a method of dyeing yarn through the steps of putting a cylindrical metal bobbin or a cylindrical plastic bobbin, on which yarn is wound up, into a dyeing vessel, impregnating the yarn with dyes in the dyeing vessel, and supplying steam of a high temperature to dye the yarn has been mainly used.

[3] However, because the cylindrical metal bobbin adopts a single body which has no division into an upper part and a lower part, it has several problems in that its dyeing effect is deteriorated since it cannot easily cope with flexibility of the yarn, and in that it is complicated to use and causes a heavy financial burden since it cannot be used to texturizing machines of different standards due to incompatibility and bobbins of various sizes must be prepared for the texturizing machines of different standards.

[4] Furthermore, the cylindrical plastic bobbin has a merit in that it is inexpensive since it is made of synthetic resin material. However, the cylindrical plastic bobbin also has several problems in that it cannot be reused since its outward shape is transformed due to the property of synthetic resin weak in high temperature when it is used for a predetermined period of time, and hence, is destroyed by fire or crushed to thereby cause an environmental pollution and an economic loss since it is necessary to buy a new bobbin. Moreover, the plastic bobbin has another problem in that the bobbin is transformed and the yarn wound on the plastic bobbin is stuck to the plastic bobbin since the plastic bobbin is processed at a high temperature while dyeing, and hence, it causes a vast damage to dyeing companies.

[5] In the meantime, when the plastic bobbin is used for two or three months, it is transformed due to the high temperature and gets short due to abrasion of both sides thereof, and the yarn is turned into destroyed yarn since the surface of the bobbin is melted. Such a bad bobbin is classified as industrial wastes which are impossible to treat, and hence, there is some troublesomeness that more workers are additionally needed to process the destroyed yarn stuck on the surface of the bobbin. That is, because a small quantity of yarn remains after yarn winders, twisters and various bobbins for dyeing are used, the remnants wound on the bobbins must be essentially processed in order to reuse the bobbins.

[6] In general, on the work spot, a worker has to remove the remnants wound on the bobbin manually one by one using a separate cutter blade, so that it takes much time to process the remnants of the bobbin and the worker is always confronted with danger since he or she uses the cutter blade. Additionally, because the cutter blade must be in close contact with the bobbin to process the remnants wound on the bobbin, the surface of the bobbin may be damaged or the cutter blade may be broken while working, and accordingly, there is a uneconomic problem in that the worker has to buy a new component or replace the damaged component with a new one. Disclosure of Invention Technical Problem

[7] Accordingly, the present invention has been made in an effort to solve the above- mentioned problems occurring in the prior arts, and it is an object of the present invention to provide a remnants processing unit of a bobbin for a dyeing machine, which can reduce time to process remnants from the bobbin and ensure a worker s safety by easily processing remnants on a bobbin, thereby enhancing work efficiency. Technical Solution

[8] To achieve the above objects, the present invention provides a remnants processing unit of a bobbin for a dyeing machine comprising: a plurality of guide bars respectively having an arc-shaped section; an auxiliary guide bar having an arc-shaped section, the auxiliary guide bar being disposed in a line that the auxiliary guide bar vertically gets in contact with any one of the plural guide bars and fixed to the guide bar through welding; a slit formed between the guide bar and the auxiliary guide bar in such a way that the blade is inserted into the slit to thereby guide the blade; and indication portions respectively formed on outer circumferential surfaces of upper and lower ring covers in such a way as to be located in a straight line with the slit formed between the guide bar and the auxiliary guide bar, so that the blade can be exactly located in the slit when remnants are processed from the bobbin.

Advantageous Effects

[30] As shown in FIGS. 1 to 4, each of plural guide bars 14 has an arc-shaped section, and an auxiliary guide bar 15 having an arc-shaped section is disposed in a line that the auxiliary guide bar 15 vertically gets in contact with any one of the plural guide bars 14 and fixed through welding. A slit 16 to which a blade 21 is fit is formed between the guide bar 14 and the auxiliary guide bar 15 to guide the blade 21.

[31] Indication portions 12 and 13 are respectively formed on outer circumferential surfaces of upper and lower ring covers 10 and 11 in such a way as to be located in a straight line with the slit 16 formed between the guide bar 14 and the auxiliary guide bar 15, so that the blade 21 can be exactly located in the slit 16 when remnants are processed from a bobbin 20. That is, the upper and lower ring covers 10 and 11 respectively having the indication portions 12 and 13 are so formed that the blade 21 is fit into the slit 16 formed between one of the plural guide bar 14 and the auxiliary guide bar 15. In this instance, it is preferable that the upper and lower cover rings 10 and 11 are respectively fixed to the top and the bottom of the guide bars 14 and the auxiliary guide bar 15 fixed and welded to a separate jig (not shown).

[32] In the meantime, the upper ring cover 10 and the lower ring cover 11 respectively have the indication portions 12 and 13 respectively molded on the outer circum- ferential surfaces thereof by the external pressure. Furthermore, as shown in FIGS. 2 and 4, the indication portions 12 and 13 are convexly or concavely molded on the inner or outer circumferential surfaces of the upper ring cover 10 and the lower ring cover 11. Moreover, a support ring 17 is mounted on the inner faces of the guide bars 14 and the auxiliary guide bar 15 and integrally fixed to the inner faces of the guide bars 14 and the auxiliary guide bar 15 through welding. In this instance, the support ring 17 is in a round form in order to support the guide bars 14 and the auxiliary guide bar 15 and prevent that the yarn presses or bends the guide bars 14 and the auxiliary guide bar 15. Additionally, in order to prevent sliding of the yarn, sliding prevention portions 19 are respectively formed on the outer circumferential surfaces of the upper ring cover 10 and the lower ring cover 11.

[33] As shown in FIG. 8, the bobbin 20 for dyeing may be configured in a straight-type cylindrical form, and in this instance, it is natural that the straight-type cylindrical bobbin 20 also has the indication portions 12 and 13 and the slit 16.

[34] In the meantime, as shown in FIGS. 9(a) and 9(b), each of the upper and lower ring covers 10 and 11 has a

U or

J shaped section in such a way that another bobbin 20 can be piled on the bottom face thereof. As shown in FIG. 10, each of the upper and lower ring covers 10 and 11 may be configured as a coil ring cover 18, which is formed in such a way as to mold a round bar of a predetermined diameter and has a coil-shaped sliding prevention portion 19, to thereby prevent sliding of the yarn.

[35] Finally, as shown in FIGS. 3 and 4, the plural guide bars 14 and the auxiliary guide bar 15 are firmly welded to the upper and lower ring covers 10 and 11 and the support ring 17 to thereby meet the wanted form of the bobbin 20 for dyeing.

[36] Hereinafter, the working and effect of the bobbin for dyeing according to the preferred embodiment of the present invention will be described in detail as follows.

[37] The yarn for dyeing is wound up on each of the plural bobbins 20, a plurality of the bobbins 20 are perpendicularly piled up on a nozzle fixed inside a dyeing vessel (not shown), and a dyeing liquid and dyes are put in the dyeing vessel in order to carry out dyeing at high pressure. In this instance, the bobbin 20 for dyeing includes the upper ring cover 10 and the lower ring cover 11 respectively having the concavely or convexly formed indication portions 12 and 13, and the guide bars 14 and the auxiliary guide bar 15 fixed between the upper ring cover 10 and the lower ring cover 11 to thereby form the cylindrical bobbin 20 for dyeing. [38] Moreover, the guide bars 14 and the auxiliary guide bar 15 are fixed to a separate jig

(not shown), and then, integrally welded with the support ring 17,which is assembled to the guide bars 14 and the auxiliary guide bar 15, in such a way as to keep the fixed form.

[39] In the meantime, as shown in FIGS. 9(a) and 9(b), the inner faces of the upper and lower ring covers 10 and 11 are respectively formed in the

U or

J shape in such a way that a plurality of bobbins 20 for dyeing can be piled up with one another. In the above state, as shown in FIGS. 3 and 4, the slit 16 for receiving the blade 21 is formed between one of the guide bars 14 and the auxiliary guide bar 15, which is in close contact with the guide bar 14. At least one slit 16 is formed between the guide bar 14 and the auxiliary guide bar 15 and at least one indication portion 12 and at least one indication portion 13 are respectively formed on the upper ring cover 10 and the lower ring cover 11 to thereby easily process the remnants.

[40] Accordingly, a worker carries out a cutting work to process the remnants in a state where the blade 21 gets in contact with the slit 16 located in a straight line with the indication portion 12 formed on the outer circumferences of the upper ring cover 10 as shown in FIGS. 5 to 7, and in this instance, the blade 21 inserted into the slit 16 can be vertically moved in safety without being separated to the outside. That is, the indication portions 12 and 13 for indicating a position that the blade 21 gets in contact with the slit 16 are formed on the outer circumferences of the upper and lower ring covers 10 and 11, so that the worker can carry out the work by rule. The indication portions 12 and 13 are concavely or convexly molded by the external pressure, and as shown in FIGS. 2 and 4, the other sides of the indication portions 12 and 13 can be respectively fit and fixed to the inner faces of the upper ring cover 10 and the lower ring cover 11.

[41] As shown in FIG. 7, the upper ring cover 10 and the lower ring cover 11 are piled up in such a way that the upper ring cover 10 is received into the lower ring cover 11 without a separation from each other. The dyeing liquid supplied from the nozzle is transferred between the guide bars 14 and the auxiliary guide bar 15, which have a wider space, so that the dyeing liquid can be supplied to the piled-up plural bobbins 20 in safety. Furthermore, the sliding prevention portions 19 for preventing sliding of the yarn are respectively formed on the outer circumferential surfaces of the upper and lower ring covers 10 and 11 to thereby enhance work efficiency. The upper and lower ring covers 10 and 11 may be respectively configured as a coil ring cover 18, which is formed in such a way as to mold a round bar of a predetermined diameter. Accordingly, since the upper and lower ring covers 10 and 11 includes the sliding prevention portion 19 and the indication portions 12 and 13, the present invention can carry out the cutting work in more various ways. Industrial Applicability [42] As described above, the remnants processing unit of the bobbin according to the present invention can be mass-produced, guarantee a great deal of economical gains to many companies due to its economical efficiency when it is compared with the conventional plastic bobbins and iron bobbins, and solve various problems related with melting of yarn, a change in colors, being stained, destruction of yarn, treatment of bad bobbins, and a change in the form of the bobbins, and hence, is of a high value in industrial use.
