In knitting machine 1, mechanically carry out the needle selection of the knitting needle on the needle-bar 2 with needle selection cylinder etc. as knitted fabric product knitted glove, socks.And, also be provided with the cutting machine that cuts off stocking yarn, lastex 5, the binding-off machine that keeps front end etc.Described control when CPU13 weaves by braiding drive division 15.And CPU13 carries out the control of lastex transport 8 by yarn feeding drive division 16.In the memory 14, be set in the amount of the lastex 5 that each stroke of for example corresponding cam carrier 3 of stage midway of each knitted fabric product of braiding should send as control data.Nozzle drive division 17 drives the open and close valve 18 that is located on the compressed-air actuated feed path, thereby control is from the air ejection of nozzle 9.
In the knitting machine 1 of said structure, after the operator can be arranged at stocking yarn, lastex 5 on the knitting machine 1, successively, making knit fabric product automatically.The automatic braiding of knitted fabric product was from just carrying out in the past, but in the knitting machine 1 of present embodiment, can also carry out the initial setting of the tension force of lastex 5 automatically with the clothes unit of knitted fabric product.
Fig. 2 is illustrated in the knitting machine 1 of Fig. 1 and makes control device 10 automatically carry out an order of the initial setting of lastex 5.Begin order from step a0, the operator is installed to lastex yarn tube 6 on the knitting machine 1 in step a1, and the lastex 5 that will pull out from lastex yarn tube 6 be arranged at from yarn feeder 4 by lastex transport 8 and broken end sense switch 7 on the binding-off machine of needle-bar 2 etc.In step a2, stretch lastex 5.When insufficient the and tension force of the stretching of lastex 5 was more weak, broken end sense switch 7 detected and is broken end in step a3.When in step a3, detecting, return step a2 to broken end.When in step a3, not detecting broken end,, operation inputting part 11 is represented the operation of the situation that end is set of lastex 5 at step a4.
The order that step a5 is later is carried out automatically according to the program behavior of CPU13.In step a5, send lastex 5, tension recovery thus from lastex transport 8.In step a6, judge whether to detect the lax of tension force as broken end by broken end sense switch 7.When not detecting broken end, return step a5.At step a6, when detecting tension force lax as broken end, in step a7, stop to send of lastex 5 immediately.The tension force of lastex 5 becomes a reference value that broken end sense switch 7 detects as broken end.That is, become the benchmaring step from step a5 to step a7.In step a8, in the time of from nozzle 9 ejection air, lastex transport 8 is a certain amount of lastex 5 of debatching only.Because from nozzle 9 ejection air, thus can prevent from lastex transport 8 be deposited in to the lastex 5 that lastex yarn tube 6 sides are regained guiding parts 8d the hole around etc. and twine.
The part of being clamped lastex 5 by the conveying roller 8a of lastex transport 8 and pushing roller 8c is to being regarded as necessarily by the length of the feed path of the part of the front end of the maintenance lastexes 5 such as binding-off machine of needle-bar 2.Because only debatching is a certain amount of from the lastex 5 of this certain-length, thereby remaining lastex 5, under the tension force that broken end detects, become the length of certain-length and a certain amount of difference, but stretch with certain-length, tension force increases the amount corresponding with extensibility.That is, step a8 becomes tension force setting step.
In step a9, carry out the braiding of the knitted fabric product of 1 clothes.Broken end sense switch 7 carries out the detection action as the broken end of original function.In step a10, judge according to whether weaving predetermined production number etc. whether braiding finishes.Be judged as when not finishing,, thereby return step a5 because the tension force of lastex 5 detects the tension force of broken end greater than broken end sense switch 7.When step a10 is judged as the production end, finish braiding at step a11.By this order, can corresponding every clothes carry out the automatic initial setting of tension force.Lastex 5 is in the scope of strain, there are certain corresponding relations such as ratio in extensibility and tension force, thereby can necessarily begin to carry out the braiding of every clothes by making extensibility, carry out the tension force initial setting of the corresponding every clothes of tension force, thereby can eliminate cumulative errors and weave the good knitted fabric product of repeatability.In addition, the degree that cumulative errors take place hour can be carried out initial setting with a plurality of clothes units, compares and can enhance productivity with the situation that corresponding every clothes carries out initial setting.And, lastex 5 breaks end weaving midway, or the lastex 5 that makes lastex yarn tube 6 uses up and behind the lastex yarn tube 6 that more renews, under the situation of restarting to weave or proceed, also by carrying out the setting of tension force with the later same order of step a0.Wherein, the front end that keeps lastex 5 by the knitting needle of fixing braiding knitted fabric midway.And the tension force of setting also correspondingly makes them different with initial setting with the carrying out of the braiding of knitted fabric.
Fig. 3 is illustrated in and makes control device 10 automatically carry out another order of the initial setting of lastex 5 in the knitting machine 1 of Fig. 1.Begin order from step b0, the operator is installed to lastex yarn tube 6 on the knitting machine 1 in step b1, and the lastex 5 that will pull out from lastex yarn tube 6 be arranged at from yarn feeder 4 by lastex transport 8 and broken end sense switch 7 on the yarn gripper of needle-bar 2 etc.In step b2, make lastex 5 lax.When the tension force of lastex 5 was strong, broken end sense switch 7 did not detect and is broken end in step b3.When in step b3, not detecting, return step b2 to broken end.When in step b3, detecting broken end,, operation inputting part 11 is represented the operation of the situation that end is set of lastex 5 at step b4.
The order that step b5 is later is carried out automatically according to the program behavior of CPU13.In step b5, lastex transport 8 debatching lastexes 5, tension force strengthens.In step a6, judge whether not detect the increase of tension force as broken end by broken end sense switch 7.When detecting broken end, return step b5.Do not detect at step b6 and to be when broken end, eliminate the lax of tension force and exceed the tension force of benchmark, and carry out the debatching of a certain amount of lastex 5, and stop debatching at step b7.The tension force of lastex 5, a reference value according to being detected by broken end sense switch 7 conduct broken ends is set at a certain amount of with debatching and the corresponding tension force of extensibility that extend.When carrying out a certain amount of debatching because from nozzle 9 ejection air, thereby can prevent from lastex transport 8 be deposited in to the lastex 5 that lastex yarn tube 6 sides are regained guiding parts 8d the hole around etc. and twine.
In step b8, carry out the braiding of the knitted fabric product of 1 clothes.In step b9, judge according to whether weaving predetermined production number etc. whether braiding finishes.Be judged as when not finishing,, thereby in step b10, make lastex 5 lax because the tension force of lastex 5 detects the tension force of broken end greater than broken end sense switch 7.When the tension force of lastex 5 was strong, broken end sense switch 7 did not detect and is broken end in step b11.When in step b11, not detecting, return step b10 to broken end.When in step b11, detecting, return step b5 to broken end.When step b9 is judged as the braiding end, finish braiding at step b12.By this order, can also corresponding every clothes carry out the automatic initial setting of tension force.Carry out the initial setting of corresponding a plurality of clothes equally with Fig. 2, the braiding behind the broken end restarts or continues.
Fig. 4 reduced representation is as the overall structure of the knitting machine 21 of another embodiment of the invention.At the part mark same numeral corresponding with the knitting machine 1 of Fig. 1, thereby the repetitive description thereof will be omitted.On knitting machine 21, use except broken end sense switch 7, have the lastex transport 28 of benchmaring switch 27.Benchmaring switch 27 switches on/off according to the displacement of the horizontal direction that detects pulley 28a.Detect pulley 28a hang between conveying roller 8a and the pushing roller 8c to the lastex 5 of the pulley 7b of the sense switch 7 that breaks end, according to tension force and displacement.Move to the horizontal direction displacement owing to detecting pulley 28a, thus can not be subjected to lastex 5 deadweight influence and set benchmark tension force.In the control when setting tension force, change part into benchmaring switch 27 and get final product about the broken end sense switch 7 of Fig. 2 and Fig. 3.
Under the situation that benchmaring switch 27 and broken end sense switch were arranged in 7 minutes, the sense switch 7 that only will break end is used in the detection of broken end in this wise.The detection of benchmark tension force is not preferably carried out in detecting the tension range of broken end, establishes the tension force that benchmark tension force detects greater than broken end in advance.Also can also be also used as broken end and detect, and not use broken end sense switch 7 by benchmaring switch 28.
Antiwind mechanism when regaining lastex 5 fast as lastex transport 28 uses and regains arm 29.Regain arm 29 and open in 2005-120531 number disclosed debatching arm the spy identical.Make when regaining arm 29 actions, as to the operating state 29b that represents with double dot dash line, being rotated displacement, introducing the retracted state 5b that extremely represents with double dot dash line with lastex 5 as with the common state 5a that realizes representing and it is relaxed from the dormant state 29a that represents with solid line.Regain the driving of arm 29, arm drive division 37 can be set on control device 30, and be undertaken by the control of being undertaken by CPU13.In addition, replace regaining arm 29, also can use the nozzle 9 of Fig. 1.And, can also replace nozzle 9 and use withdrawal arm 29 at Fig. 1.
As antiwind mechanism, relatively as the air type of nozzle 9 and as when regaining arm 29 arm-type, preferred air type.In arm-type, because that the rotation by arm absorbs is lax, thereby according to length, the rotation amount of arm, conveying roller 8a is loose and the debatching volume production is given birth to restriction, thereby can not tackle the many situations of debatching amount.In air type since only eliminate by the opening/closing of air ejection lax, thereby conveying roller 8a can not relax and the debatching amount without limits, thereby even the debatching amount also can tackle for a long time.And, in arm-type, might apply unwanted tension force when carrying lastex 5, with respect to this, in air type, when closing the ejection of air, when carrying lastex 5, can not apply unwanted tension force.And, in the air type as nozzle 9, owing to can constitute major part by nozzle 9 and open and close valve 18, thus with as need arm, to the withdrawal arm 29 of the guiding parts of arm front end guidance stretch yarn, the rotary driving source of arm etc. arm-type comparing, structure, control simpler.
By Fig. 2 and order shown in Figure 3, when step a1 or step b1 are provided with lastex 5, can automatically distinguish by whether detecting broken end.That is, when lastex 5 was set, the operator only carried out the operation that end is set shown in step a4 or the step b4.CPU13, in order to investigate the switching of on/off of broken end sense switch 7, lastex 5 stretches and can not detect to broken end the time, carries out the transition to the later order of step a5 of Fig. 2, lastex 5 relaxes and detects when being broken end, and the later order of step b5 that carries out the transition to Fig. 3 gets final product.
In the above description, as knitting machine 1,21, in the short straight-bar machines of the needle-bar 2 of knitted glove, socks, use the present invention, but also can the long general straight-bar machines of needle-bar, circular knitting machine etc. be used for horizontal volume various knitting machines, be used for the vertical knitting machine of compiling and similarly use the present invention.The present invention is simple method, though can not strictly set tension force, can repeatability implement well in no problem scope in the fine finishining of knitted fabric.
