DETAILED DESCRIPTION OF THE INVENTION

[0016] In this detailed description, the subject matter dyeing machine (1) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

[0017] In FIGS. 1 and 2, representative schematic views of the subject matter dyeing machine (1) are given. The present invention relates to a dyeing machine (1) which provides dyeing of yarn (223) with desired colors. Said dyeing machine (1) has at least one spraying mechanism (10) on at least one body (20).

[0018] In said body (20), dyeing is realized during wrapping of the yarn (223) from at least one first bobbin (21) to at least one second bobbin (22). The unwinding of the yarn (223) from said first bobbin (21) and the winding of the yarn (223) onto said second bobbin (22) are provided by means of driving of at least one drum (23) by means of at least one first drive element (231). The surfaces of the second bobbin (22) and the drum (23) are in contact with each other and as the drum (23) rotates around its own axis, the second bobbin (22) also rotates around its own axis. The drum (23) is positioned in a parallel manner to the bobbin center axis (222) and it is connected to said first drive element (231) from one end thereof. The connection of the drum (23) and the first drive element (231) to each other can be provided by means of elements like belt, chain or geared wheel. The drum (23) is connected to the first drive element (231) from one end and it is connected to at least one second drive element (232) from the other end. Said second drive element (232) moves the drum (23) in a direction which is opposite to the operation of the first drive element (231). At least one balloon breaker (26) and at least one shuttle (25) guide the wrapping of yarn (223) onto the second bobbin (22) moved by the drum (23). Said shuttle (25) is connected to at least one third drive element (251) and moves in a parallel manner to the bobbin center axis (222). The balloon breaker (26) is an element known in the art, which provides more rapid unwrapping of the yarn (223) from the first bobbin (21). At least one each orthogonal guide (24) is positioned at the two sides of the body (20). On said orthogonal guide (24), at least one bobbin carrier (224) and at least one sprayer drive mechanism (17) are positioned in a movable manner in the vertical axis. The second bobbin (22) is positioned on said bobbin carrier (224) and the vertical movement of the bobbin carrier (224) is provided as the yarn (223) widens the periphery of the second bobbin (22) during dyeing. On the bobbin carrier (224), there is a plug-and-remove structure which facilitates fixation and removal of the second bobbin (22).

[0019] The spraying mechanism sprays the dye onto the second bobbin (22) and dyes the second bobbin (22). Spraying of the dye onto the second bobbin (22) is realized by means of at least one sprayer (16). In a possible embodiment of the present invention, there are pluralities of sprayers (16) and said sprayers (16) provide dyeing of the yarn (223) with different colors. The sprayer (16) is positioned on said sprayer drive mechanism (17) and it is connected to at least one piston (172) and at least one sensor (18). Said sensor (18) detects the decrease of the distance between the second bobbin (22) and the sprayer (16) during winding and positions the sprayer drive mechanism (17). Positioning of the sprayer drive mechanism (17) is provided by means of moving by at least one fourth drive element (171). Thanks to this, the sprayer (16) sprays dye to the yarn (223) provided on the second bobbin (22) at the desired position. Besides, by means of said piston (172), the sprayer (16) can be approached to and diverged from the second bobbin (22). The sprayer (16) is connected by using at least one hose (15) by means of at least one pump (14). In a possible embodiment of the present invention, said pump (14) has a peristaltic structure and provides usage of desired amount of dye. The pump (14) is connected to at least one dye kier (11), at least one salt kier (12) and at least one soda kier (13) by using the hose (15). In order to increase the dyeing quality in said dye kier (11), temperature control and stirring equipment can be positioned.

[0020] On the body (20), at least one control unit (30) and at least one memory unit (31) connected to the control unit (30) are positioned. Said memory unit (31) is the electronic unit where the work flow, existing on the yarn (223), is recorded beforehand. The control unit (30) controls and guides all movable elements of the dyeing machine (1) depending on the orientation of the operator and depending on the dyeing process recorded in the memory unit (31).

[0021] In more details, the subject matter dyeing machine (1) provides dyeing of the yarn (223) during wrapping of the yarn (223) from the first bobbin (21) onto the second bobbin (22). Accordingly, the operator loads the dyeing report to the memory unit (31) in electronic medium. The control unit (30) moves the first drive element (231) in the direction of the information received from the memory unit (31) and rotates the drum (23) around its own axis. The drum (23), which rotates around its own axis, rotates the second bobbin (22) and begins wrapping the yarn (223). During wrapping of the yarn (223), the sprayer (16) sprays the dye onto the yarn (223) and provides dyeing of the yarn (223). During wrapping of the yarn (223) onto the second bobbin (22), the shuttle (25) controls the wrapping angle depending on the increasing diameter of the second bobbin (22) and provides continuous dyeing onto the yarn (223). The third drive element (251) provides movement of the shuttle (25) and is guided by the control unit (30). As the diameter of the second bobbin (22) increases together with the winding, the bobbin carrier (224) rises on the orthogonal guides (24). The sensor (18) detects the rising second bobbin (22) and positions the sprayer drive mechanism (17) dependingly. The sprayer (16) realizes dyeing by means of spraying the dye onto the second bobbin (22). Pressurized spraying is realized by means of the dye received from the dye kier (11) by the pump (14). After the dyeing process, the sprayer (16) sprays the salt, received from the salt kier (12), onto the second bobbin (22) and sprays the soda, received from the soda kier (13), onto the second bobbin (22).

[0022] Stamping dyeing is also realized onto the second bobbin (22) besides spray dyeing. The stamping dyeing is the process of spraying of the dye onto the second bobbin (22) by the sprayer (16) locally. By means of stamping dyeing, the desired short-distance color changes are obtained with high precision on the yarn (223). For this purpose, while dyeing is being realized, the rotation of the second bobbin (22) is stopped and a stamping region (221) is detected on the second bobbin (22) by the sensor (18), and the stamping region (221) is brought to the same alignment with the sprayer (16) by using the second drive element (232). When the stamping region (221) and the sprayer (16) are aligned with each other, said piston (172) approaches the sprayer (16) to the second bobbin (22). Afterwards, the stamping region (221) is dyed by means of spraying of the dye by the sprayer (16).

[0023] Thus, the yarn (223) is dyed with the desired length and with the desired colors. Moreover, by inversely turning the drum (23) and by stamping dyeing onto the second bobbin (22), the dyeing quality is increased and short-distanced dye passages can be obtained.

[0024] The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
