Braid movement based on each system 25 is undertaken by repeatedly carrying out following steps: the pinhock of the front end of knitting needle 2 is entered to tooth mouth 10, and the stocking yarn 21 that the yarn-feeding port from thread-carrier 15 151 is supplied with is pulled into needle-bar 11a, 11b.The cam carrier 12 of front and back makes a plurality of thread-carrier 15 interlocks and making knit fabric 22.The braiding of knitted fabric 22 according to based on inputted the weave data generating in advance controller 4 control and carry out, knitted fabric 22 weaves below tooth mouth 10.The action of the system 25 based on cam carrier 12 and knitting needle 2 is also automatically carried out by controller 4 based on weave data, and the shift motion that cam carrier 12 moves is also based on weave data etc. and optimization.In addition, thread-carrier 15 near braiding end 22a in foreign side's standby of the knitting width of knitted fabric 22.The position of readiness of thread-carrier 15 is, near the foreign side of knitting width of the knitted fabric 22 that discharges from interlock after cam carrier 12 makes thread-carrier 15 interlocks, to be stored in controller 4.And a plurality of thread-carriers 15 overlap and stop at stop position sometimes, also this situation is shown in to the monitor (not shown) of straight-bar machines 1 and urges the position correction of each thread-carrier 15.In addition, near switch servomotor the foreign side of the moving direction of each cam carrier 12 by the knitting width at knitted fabric 22 direction of rotation is reversed.
Fig. 4 is the top view of cam carrier 12 that roughly represents the front and back of straight-bar machines 1, on each cam carrier 12, be equipped with respectively corresponding with 2 systems 25 in advance and the lopping tablet press mechanism 3 of rear row.This each lopping tablet press mechanism 3 possesses the lopping compressing tablet 31 that is roughly L word shape and the driving mechanism 32 that drives lopping compressing tablet 31.Lopping compressing tablet 31 possesses: the arm 311 extending along fore-and-aft direction; And cam follower 312, in this cam follower 312, base end part 315 links integratedly with one end of described arm 311, and extend at the moving direction rear of front end 316 from this base end part 315 to the cam carrier 12 with described arm 311 quadratures.Driving mechanism 32 possesses: the stepper motor 321 that is installed on rectangular box-like housing 30; And the driving shaft of this stepper motor 321 link and between 2 positions the linkage 322 of actuating arm 311.In addition, also can utilize the actuating arms 311 such as the triangle that links with the driving shaft of stepper motor 321 or groove triangle, make thus cam follower move to setting position and reset position.
Fig. 5 means near the vertical profile side view of motion track of the cam follower 312 of the lopping compressing tablet 31 tooth mouth 10, the cam follower 312(312a～312e of lopping compressing tablet 31) describe circular-arc motion track between the setting position while pressing knitted fabric 22 in tooth mouth 10 and these 2 positions of reset position that deviate from from knitted fabric 22 and move.Arm 311 configures in the mode not contacting with yarn-feeding port 151 between from setting position to reset position.
Fig. 6 represents the top view of lopping tablet press mechanism 3, and Fig. 7 represents the stereogram of lopping tablet press mechanism 3.The base end part 315 of lopping compressing tablet 31 is driven by the driving of stepper motor 321 via linkage 322, makes to utilize the knitted fabric 22 of stocking yarn 2 braidings of supplying with from the yarn-feeding port 151 of thread-carrier 15 to be switched to the setting position (position representing Fig. 7 (a)) that utilizes cam follower 312 to press and the reset position (position representing Fig. 7 (b)) deviating from from knitted fabric 22.Now, the situation that the base end part 315 of the cam follower 312 of lopping compressing tablet 31 has been switched to setting position is detected by setting position sensor 313, and the situation that has been switched to reset position is detected by the reset position sensor 314 as reset position detecting unit.These position sensors 313,314 consist of proximity transducer, utilize via arm 311 and make the moving of swing sheet 323 of the linkage 322 that the base end part 315 of cam follower 312 swings between setting position and reset position and detect.In addition, also can be, the base end part 315 of the cam follower 312 of lopping compressing tablet 31 has been switched to the situation of reset position, and by change-over switch, the switching to reset position detects, or output or the instruction of the pulse signal by the switching use to reset position for stepper motor detect.
And each lopping tablet press mechanism 3 possesses: reset condition detecting unit 33, detects the front end 316 of this cam follower 312 when the base end part 315 that makes cam follower 312 has been switched to reset position and whether resets into reset position (position shown in Fig. 6 and Fig. 7 (b)); Identifying unit 34, the testing result based on this reset condition detecting unit 33 is judged to be cam follower 312 and interferes with the yarn-feeding port 151 of thread-carrier 15; And avoid interfering motor unit 35, when interfering, the yarn-feeding port 151 that is judged to be cam follower 312 and thread-carrier 15 by described identifying unit 34 avoid the interference of avoiding of the two interference of 312,151 to move.In this situation, the detection that whether has reset into reset position based on front end 316 reset condition detecting unit 33, cam follower 312 cam carrier 12 for be withdrawn into knitted fabric 22 knitting width foreign side and reverse thereby while stopping, carrying out with the detection of the base end part 315 of 314 pairs of cam followers 312 of reset position sensor simultaneously.
Reset condition detecting unit 33 possesses: swing sheet 331, length direction roughly pars intermedia is supported on housing 30 and swings between 2 positions; Test section 333, when detecting at this swing sheet 331 the non-detection position from 2 positions (position shown in Fig. 7 (a)) (position shown in Fig. 7 (b)) swinging to detection position, the front end 316 of cam follower 312 has reset into reset position.Swing sheet 331 and possess balance weight 332 at its length direction one distolateral (being upper end side in Fig. 6 and Fig. 7), by this balance weight 332 to the non-detection position side application of force.And, test section 333 consists of proximity transducer, if swing balance weight 332 butts of one end of sheet 331, the front end 316 that detects cam follower 312 does not reset into reset position, on the other hand, if the front end 316 of this cam follower 312 and the other end (being lower end in Fig. 6 and Fig. 7) butt that swings sheet 331 when the base end part of cam follower 312 315 has been switched to reset position, the balance weight 332 of one end of the swing sheet 331 of resisting the application of force of balance weight 332 and swinging to detection position deviates from from test section 333, thereby the front end 316 that detects cam follower 312 has reset into reset position.Thus, can utilize the simple structure being formed by swing sheet 331 and test section 333 to form reset condition detecting unit 33.
In addition, swing that sheet 331 also can replace balance weight 332 and by helical spring etc. to the non-detection position side application of force, in this situation, with respect to the vibration of cam carrier and reliability is high, more preferably.
Identifying unit 34 is located at controller 4, have nothing to do with the switching to reset position that detects the base end part 315 of cam follower 312 by reset position sensor 314, and only when not detecting the reset condition to reset position of front end 316 of cam follower 312 by reset condition detecting unit 33, be judged to be cam follower 312 and interfere with the yarn-feeding port 151 of thread-carrier 15.In addition, avoid interfering motor unit 35 to be located at controller 4, application stroke extension unit, the trip extension unit is avoided the interference of the yarn-feeding port 151 of cam follower 312 and thread-carrier 15 by the prolongation to the shift motion along direction of cam carrier 12.Control based on the trip extension unit is automatically carried out by controller 4 according to weave data, the front end 316 of the cam follower 312 of the lopping compressing tablet 31 of rear row is withdrawn into after the foreign side of knitting width of knitted fabric 22, for example, with ormal weight (20～30mm degree) shift motion of cam carrier 12 is extended, until the position not interfering with the yarn-feeding port 151 of each thread-carrier 15.In addition, control based on stroke extension unit can be also, the shift motion that makes cam carrier extends until detect the reset condition to reset position of the front end of cam follower by reset condition detecting unit, at the time point of the reset condition to reset position that the front end of cam follower detected, makes cam carrier reversion.
Herein, each cam carrier 12 based on controller 4 and the control step of each lopping tablet press mechanism 3 based on Fig. 8 explanation.If use in advance and the lopping tablet press mechanism 3 of rear row by 2 systems 25 of each cam carrier 12.
In step S1, start straight-bar machines 1 and carry out after the initial setting of each portion, read in the weave data about knitted fabric to be woven 22.Weave data is such as via recording mediums such as various disks, or utilizes via LAN(Local Area Network) etc. data communication, be read into storage part.
In step S2, the then preparation of row to be woven, in step S3, judges whether next row is final row.If not final row, in step S4, according to weave data, whether judgement uses lopping compressing tablet 31 in next row.Using in advance and during the lopping compressing tablet 31 of rear row, owing to making each lopping compressing tablet 31 just using in present row carry out homing action in next row, therefore in step S5, when the front end 316 of the cam follower 312 of the lopping compressing tablet 31 of rear row is withdrawn into the foreign side of knitting width of knitted fabric 22, make the base end part 315 of cam follower 312 be switched to reset position.The switching to reset position of the base end part 315 of this cam follower 312 is confirmed by reset position sensor 314.In addition,, when only having carried out the braiding of knitted fabric 22 by system 25 in advance, when the front end 316 of lopping compressing tablet 31 is in advance withdrawn into the foreign side of knitting width of knitted fabric 22, the base end part of cam follower 312 315 is switched to reset position.
In step S6, whether the front end 316 that utilizes test section 333 to detect cam follower 312 resets into reset position.Only, when the front end 316 that cam follower 312 detected by this detection does not reset into reset position, in step S7, be judged to be cam follower 312 and interfere with the yarn-feeding port 151 of thread-carrier 15.Thus, the testing result in fact whether yarn-feeding port 151 based on cam follower 312 and thread-carrier 15 interfere is held the two interference state of 312,151 reliably, can improve judgement precision.
By the judgement of step S7, when the yarn-feeding port 151 that is judged to be cam follower 312 and thread-carrier 15 interferes, in step S8, avoid interfering after action, in step S9, make cam carrier 12 reversions, described to avoid interfering action be following action: the front end 316 of the cam follower 312 of the lopping compressing tablet 31 of rear row is withdrawn into after the foreign side of knitting width of knitted fabric 22, for example, with ormal weight (20～30mm degree) by the shift motion of cam carrier 12 directly along extending along direction, until the position not interfering with the yarn-feeding port 151 of each thread-carrier 15.Thus, only by the shift motion of cam carrier 12 is extended, just can avoid simply the interference of the yarn-feeding port 151 of cam follower 312 and thread-carrier 15.
On the other hand, if by the detection of step S6, the front end 316 that detects cam follower 312 has reset into reset position, in step S10, being judged to be cam follower 312 does not interfere with the yarn-feeding port 151 of thread-carrier 15, in step S9, do not make the shift motion of cam carrier 12 extend, and make cam carrier 12 reversions in the position of foreign side that is withdrawn into the knitting width of knitted fabric 22.Thus, compare with the technology based on both 312,151 possibilities that interfere, the shift motion of cam carrier being extended to more than necessity by weave data, the shift motion of the cam carrier 12 of each row shortens 20～30mm degree, can improve braid efficiency.And, even when the base end part of cam follower 312 315 being switched to reset position in the knitting width of the knitted fabric 22 not interfering with the yarn-feeding port 151 of thread-carrier 15 and the recovery to reset position of front end 316 also not detected, the front end 316 that also can be judged to be simply at cam follower 312 by identifying unit 34 has produced the unfavorable conditions such as crooked, can prevent from reliably still using when front end 316 has produced unfavorable condition the situation of cam follower 312.
In this situation, by identifying unit 34, while having judged off and on or continuously the interference of cam follower 312 and the yarn-feeding port 151 of thread-carrier 15 at the same position of the moving direction of cam carrier 12, also can make the shift motion of the later cam carrier 12 at this position extend.Thus, the state that can eliminate the foreign side of the knitting width that is withdrawn into knitted fabric 22 at same position from cam carrier 12 and stop starts all to make the shift motion of cam carrier 12 to extend at every turn and makes the stiff inharmonious sense of movement of cam carrier 12, can make cam carrier 12 move smoothly until the backward position after extending.
In addition, in the situation that use thread-carrier 15 under the state that yarn-feeding port 151 is declined, be not limited to same position, when other position cam carriers 12 stop, cam follower 312 also may interfere with yarn-feeding port 151.Therefore,, when both interference of 312,151 easily occur beyond cam carrier 12 is withdrawn into the position of foreign side of knitting width of knitted fabric 22, also can be judged as the demonstration that has unfavorable condition and urges adjustment at the monitor of straight-bar machines 1 etc.

In addition, in present embodiment, as avoiding interfering motor unit 35, applied the stroke extension unit of the shift motion prolongation that makes cam carrier 12, but also can apply following thread-carrier mobile unit: have and rely on the drive division self make thread-carrier move, by this drive division, make thread-carrier rely on self to move after the interference of avoiding with cam follower to the direction of the opposite direction of advancing with cam carrier and move and return until origin-location.In this situation, do not need to make the shift motion of the cam carrier of each row to extend, can further improve braid efficiency.
In addition, in present embodiment, reset condition detecting unit 33, by forming at the distolateral test section 333 that has the swing sheet 331 of balance weight 332 and consist of proximity transducer of length direction one, but also can be replaced to balance weight and utilizes spring etc. to swinging sheet to the non-detection position side application of force.The swing sheet that the front end that in addition, also can use one end swing to be supported on freely housing and cam follower swings to detection position with being biased the other end butt of non-detection position side.In addition, can be also the reset condition detecting unit that front end by utilizing the butt sheet of switching on the butt of the front end of cam follower to detect cam follower resets into the situation of reset position.And, can be also the reset condition detecting unit that the front end that utilizes proximity transducer or the image analysis based on ccd video camera to detect cam follower resets into the situation of reset position.
In addition, in present embodiment, make the front end 316 of cam follower 312 detect the reset condition of the front end 316 of this cam follower 312 with swinging the other end butt of sheet 331, but also can make to compare front end, lean on a little the leading section of the cam follower of cardinal extremity to detect the reset condition of the leading section of this cam follower with swinging the other end butt of sheet.
In addition, in present embodiment, near the situation that each cam carrier 12 is reversed the foreign side of the knitting width of knitted fabric 22 has only been described, but on knitted fabric during weave pattern etc., when each cam carrier is reversed in the knitting width of knitted fabric, also consider the interference of the leading section of cam follower and the yarn-feeding port of thread-carrier, therefore, in the situation that make cam carrier reversion also can carry out the same control based on controller in the knitting width of knitted fabric, this is self-evident.
And, in present embodiment, when being judged to be cam follower 312 and having interfered with the yarn-feeding port 151 of thread-carrier 15, the interference of avoiding of the shift motion prolongation of cam carrier 12 is moved, but this is avoided interfering action is the additional action for fear of the interference of cam follower and yarn-feeding port, at the base end part that cam follower detected, be switched under the state of reset position, during the situation of only not restoring at the leading section that this cam follower detected, the leading section being judged to be at cam follower produces the unfavorable conditions such as crooked.
