By adopting such structure, detergent delivery device 3 makes the part shunting and the pressurization of flow air in the first air pipe arrangement 22, utilizes air pressurized can improve the internal gas pressure of washing agent storagetank 33.Detergent delivery device 3 has improved the result of washing agent storagetank 33 internal gas pressures, can washing agent be expressed in the first air pipe arrangement 22 by washing agent supplying tubing 34.Thus, detergent delivery device 3 can be given flow air interpolation washing agent in the first air pipe arrangement 22.Be added in the first air pipe arrangement 22 washing agent in the flow air owing to be dispersed into vaporificly, be provided for each open end spinning apparatus 6 uniformly and stably.
The spinning machinery 100 of this example adopts the air shunting that will add washing agent, the structure that offers all open end spinning apparatus 6.But,, also can detergent delivery device 3 and air force feed device 21 be set for each group a plurality of spinning units 1 being divided under a plurality of groups the situation.
And the detergent delivery device of this example 3 utilizes the air after the pressurization to improve the internal gas pressure of washing agent storagetank 33, and washing agent is added in the first air pipe arrangement 22 in the flow air.But detergent delivery device 3 for example also can use electrodynamic pump to extrude washing agent from washing agent storagetank 33, and washing agent is added in the first air pipe arrangement 22 in the flow air.
Use Fig. 5 explanation owing to finish is deposited in the reason that produces tender yarn in the spinning room 65 below.Be in detail, illustrate, be stacked into the reason that produces tender yarn in the spinning room 65 owing to finish making under the situation of spinning Y with the sliver F that has been endowed finishes such as polyester.In addition, the arrow shown in the figure is provided by the flow direction of throughput direction and the air that provides of sliver F and spinning Y.
As mentioned above, the sliver F that has been endowed finish is directed into the spinning room 65 from the yarn path 61a of yarn guide member 61.Each fiber that constitutes sliver F reverses in spinning room 65 under the turn air-flow effect of air and turn (with reference to the diagram double dot dash line).At this moment, give to the finish of fiber from this fiber of turn under the effect of turn air-flow side face attached to spindle parts 62.Continue repeatedly attached to the side face of spindle parts 62 from the finish of each fiber, this finish is piled up down thickly thus.
So, the finish that is deposited in spindle parts 62 side faces becomes and is wound up into these spindle parts 62 resistance of the fiber of turn (with reference to the diagram double dot dash line) peripherally.That is, the finish result of accumulation becomes the yarn texture instability---promptly make the reason of so-called tender yarn.
Therefore, in order to prevent the generation of tender yarn, the finish that is necessary to prevent to give sliver F adheres to and is stacked in the spinning room 65.Be to be necessary to prevent to give finish to sliver F and to adhere to and be stacked on the spindle parts 62 that constitute spinning room 65 in detail.Therefore add the washing agent of optimal dose to air, provide the air that has added washing agent to become important for uniformly and stably each open end spinning apparatus 6.
As mentioned above, spinning machinery 100 usefulness detergent delivery devices 3 will prevent that finish from adhering to and the washing agent piled up adds in the air, with this air shunting, offer each open end spinning apparatus 6.As a result, spinning machinery 100 can offer washing agent each open end spinning apparatus 6 uniformly and stably.Thus, can prevent to give finish to sliver F adheres to and is stacked in the spinning room 65.The result can improve the quality bills of materials of the spinning Y that is made by spinning machinery 100.And,, therefore do not need to carry out regular cleaning owing to not having finish to adhere to and being stacked in the spinning room 65.The production efficiency that the result can make spinning machinery 100 produce spinning Y improves.
And, because each open end spinning apparatus 6 is shunted, offered to spinning machinery 100 with the air that has added washing agent, therefore can adopt flow distributor 2 and detergent delivery device 3 are respectively disposed one simple structure.Thus, can realize spinning machinery 100 miniaturizations and cost degradation.Especially because spinning machinery 100 sets the first air pipe arrangement 22 and the second air pipe arrangement 24 along the direction that disposes a plurality of spinning units 1, therefore can make structure simpler.The result can make spinning machinery 100 miniaturizations and cost degradation.
The following describes the structure that changes the supply form of washing agent according to the characteristic of sliver F.
As mentioned above, for being the synthetic fiber of raw material, there is the sliver F that has given finish with polyester etc.But,, do not have the sliver F that has given finish for being the string of representative with cotton or fiber crops etc.Therefore, this spinning machinery 100 stops to add washing agent in the air that offers open end spinning apparatus 6 when making spinning Y with the sliver F that is not endowed finish.And this spinning machinery 100 is when making spinning Y with the sliver F that has given finish, according to the characteristic changing of the sliver F addition to the airborne washing agent that offers open end spinning apparatus 6.
The addition that stops to add washing agent or changing washing agent is realized by the running status that control device C controls air pressurization device 32.Specify to, control device C and possess the control module of interpolation C1.Add control module C1 and from control chart M, access addition with the corresponding washing agent of characteristic of sliver F.Add control module C1 and will send to air pressurization device 32 with the corresponding control signal of the addition that accesses.In addition, so-called control chart M stores in order to prevent that finish from adhering to and be stacked in the spinning room 65 and the data (with reference to Fig. 6) of the only washing agent addition that draws by experiment in advance.
As shown in Figure 6, when spinning Y, add control module C1 control air pressurization device 32 and do not give flow air interpolation washing agent in the first air pipe arrangement 22 with the sliver F manufacturing of not giving finish.And, in the spinning machinery 100 of this example, close the valve 221 that is configured in the first air pipe arrangement, 22 upstreams, open the valve 241 that is configured in the second air pipe arrangement, 24 upstreams.Thus, spinning machinery 100 can offer open end spinning apparatus 6 with flow air in the second air pipe arrangement 24, only spins with the air that does not add washing agent.
On the other hand, as shown in Figure 6, when making spinning Y, add control module C1 control air pressurization device 32 and add washing agent toward flow air in the first air pipe arrangement 22 with the sliver F2, the F3 that have given finish, F4.And, in the spinning machinery 100 of this example, open the valve 221 that is configured in the first air pipe arrangement, 22 upstreams, close the valve 241 that is configured in the second air pipe arrangement, 24 upstreams.Thus, spinning machinery 100 can offer open end spinning apparatus 6 with flow air in the first air pipe arrangement 22, can spin by enough air that has added washing agent.
For example making under the situation of spinning Y, if add the accumulation that airborne washing agent seldom just can not prevent finish to the many sliver F4 of the finish of giving.Therefore, this spinning machinery 100 is adjusted to only amount according to the characteristic of sliver F4 with adding airborne washing agent to.At this moment, add control module C1 control air pressurization device 32 to strengthen the pressurization of air.
So, spinning machinery 100 can change the addition of washing agent according to the characteristic of sliver F.That is, making with the sliver F that has given finish under the situation of spinning Y, spinning machinery 100 can be toward the washing agent of interpolation in the air that offers open end spinning apparatus 6 with the corresponding optimal dose of characteristic of sliver F.Thus, can prevent to give finish to sliver F and adhere to and be stacked in the spinning room 65, can improve the quality bills of materials and the production efficiency of spinning machinery 100.And the sliver F of the enough all kinds of spinning machinery 100 energy makes spinning Y.
The following describes when at least one spinning unit 1 in a plurality of spinning units 1 is made spinning Y and add washing agent toward air in, all spinning units 1 stop the structure of interpolation washing agent in the air when not making spinning Y.
This structure realizes by the duty that control device C grasps each spinning unit 1.Specify to, the spinning control module C2 of control device C can detect removal device 8 from each spinning unit 1 yarn defect separately and receive the yarn walk signal.Detect removal device 8 at spinning control module C2 from least one yarn defect and receive under the situation of yarn walk signal, control air pressurization device 32 is to add washing agent.
On the other hand, detect removal device 8 at spinning control module C2 from all yarn defects and all can not receive under the situation of yarn walk signal, be judged as all spinning units 1 and all the spinning of manufacturing Y.So spinning control module C2 control air pressurization device 32 is not to add washing agent.
By adopting such structure, spinning machinery 100 provide the air that has added washing agent can for the open end spinning apparatus 6 that constitutes this spinning unit 1 under the situation of at least one spinning unit 1 manufacturing spinning Y.Thus, the finish that can prevent to be endowed sliver F adheres to and is stacked in the spinning room 65, can improve the quality bills of materials and the production efficiency of spinning machinery 100.And, do not make at all spinning units 1 under the situation of spinning Y, stop detergent delivery device 3 and in air, add washing agent.As a result, can reduce the consumption of the washing agent of spinning machinery 100, the reduction of the manufacturing cost of the Y that can realize spinning.
And spinning machinery 100 is not made spinning Y, is just begun to restart to make under the situation of spinning Y at all spinning units 1, except stopping to add washing agent, also stops the driving of air force feed device 21.Thus, can further reduce the manufacturing cost of spinning Y.
Under the situation that the storage capacity that the following describes washing agent in the washing agent storagetank 33 lacks than predetermined value, make all spinning units 1 stop to spin structure of manufacturing of Y.
This structure realizes by the storage capacity that control device C grasps washing agent in the washing agent storagetank 33.Specify for, spinning control module C2 receives the detection signal of the liquid level sensor 331 that is possessed from washing agent storagetank 33, grasps the storage capacity of washing agent.When from the detection signal of liquid level sensor 331 than predetermined value hour, spinning control module C2 controls the manufacturing of all spinning units 1 with the Y that stops to spin.Be that spinning control module C2 stops the drafting system 5 of formation spinning unit 1 and the drive source of yarn feeding device 7, coiler device 9 etc. in detail.And spinning control module C2 control air pressurization device 32 is to stop the interpolation of washing agent.
By adopting such structure, the storage capacity that detects washing agent when the liquid level sensor 331 of washing agent storagetank 33 than predetermined value after a little while, spinning machinery 100 can make all spinning units 1 stop to spin manufacturing of Y.Therefore, making under the situation of spinning Y, can prevent to spin with the air that does not add washing agent with the sliver F that has given finish.Thus, the finish that can prevent to be endowed sliver F adheres to and is deposited in the spinning room 65, can improve the quality bills of materials and the production efficiency of spinning machinery 100.
In addition, the spinning machinery 100 of this example is carried sliver F downwards from the top, but the present invention is not limited to such example.Also can be that the bar tube that for example will store sliver F is configured in underpart, coiler device 9 is configured in the structure of body upper.
