Summary of the invention
Thereby, the objective of the invention is to cycle numbering, the dwell time of loom and the stop reason of loom according to a pattern repetition of opening figure, prevent to shut down weft bar reliably.
According to the problems referred to above; The present invention is on the loom of the opening figure that the pattern of 3 formations more than the cycle with loom main shaft repeats; At least one of the cycle numbering that repeats corresponding to pattern of opening figure and the dwell time of loom, and the combination of loom stop reason; Actuating quantity when preestablishing action non-action state and the action of the anti-locking apparatus of multiple type shutdown weft bar, and according to these settings, control are shut down the anti-locking apparatus of weft bar (the present invention 1).
In addition; The present invention; The said cycle numbering that repeats corresponding to pattern of opening figure and the combination of loom dwell time and loom stop reason, the actuating quantity when preestablishing multiple type of action non-action state of shutting down the anti-locking apparatus of weft bar and action (the present invention 2).
In addition; The present invention; As shutting down the anti-locking apparatus of weft bar; Be provided with: the sky of the running of fell mobile device the during starting of when loom starts, moving fell and the picking when the not following starting rotating device that beats up, and corresponding to the said combination of stream oriented device, the actuating quantity when preestablishing action non-action state and action (the present invention 3).
Utilizing opening figure more than the cycle of 3 of loom main shaft, repeating on the woven fabric with a pattern; Cycle when stopping (cycle numbering) according to loom; Warp opening is in the state of remaining silent or open state; And the numbering of the cycle when stopping according to loom, the warp tension when its loom stops is different.Therefore, the fell when loom stops to move degree, and is also different because of each cycle of a pattern repetition.Therefore, setting the shutdown weft bar according to each cycle and prevent the condition of locking apparatus (actuating quantity when action non-action state and action), is the material particular in order to use the shutdown weft bar to prevent locking apparatus effectively.
The dwell time of loom has influence on the extension of warp thread.Each shuts down the anti-locking apparatus of weft bar, all will determine the length of interval of dwell time, and is set in that each interval action is failure to actuate and the actuating quantity when moving.
As the loom stop reason, have because of the bad Weft stop of picking, because of the warp stop motion of warp thread broken yarn, and because of changing that batching rolls or manually the stopping of situation such as available machine time.These stop reasons directly have influence on and prevent to shut down weft bar.In addition, usually, for warp stop motion and manually stop, action that having set the anti-locking apparatus of identical shutdown weft bar is failure to actuate and the actuating quantity when moving.
As the anti-locking apparatus of multiple shutdown weft bar, the so-called recoiling device of the fell mobile device when the fell mobile device when the ultra starting device of what is called of the free rotating device that beats up, moment of torsion increase rotating device, braking, starting.These devices, the above-mentioned cycle numbering that repeats according to pattern of opening figure and the combination of loom dwell time and loom stop reason, combination are more than two, and constitute the anti-locking apparatus of multiple shutdown weft bar.
The sky rotating device that beats up is from the restarting through during the regulation of loom, that is, the specified period number (number of pick) or the stipulated time through being set that set through loom main shaft be not with the running of picking.After loom was restarted, the strengthening gradually around song of reed, and increase the power of beating up to fell began picking near conventional running the time, to being beaten up by the weft yarn of picking.Weft yarn and since quilt when turning round with routine much at one the power of beating up beat up, so prevented the shutdown weft bar effectively.
Moment of torsion increases rotating device, is meant ultra starting device, when loom is restarted, increases the moment of torsion of loom main shaft drive motor when turning round than routine and makes its running, the power of beating up when making the later power of beating up of firm starting near routine.Use this skill and technique, 2 kinds (1) and (2) are arranged, its (1) is to be setting (300% during for example conventional the running) with the moment of torsion; After restart through the stipulated time; That is, specified period number loom main shaft, that be set (number of pick), or stipulated time through setting; Its (2) are to be setting (any one of 300%, 400%, 500% during for example conventional running) with torque setting; After restart through during certain, that is, and certain periodicity (for example 2 cycles) or the method for carrying out through the regular hour.
Fell mobile device during braking after stop signal produces, in motor braking beginning and action before and after it, when action, makes and sees motor off or the coiling motor just changes, makes fell to move.With this, carry out under the halted state, will move (to seeing moving of side off) because of the fell of warp tension and estimate in interior correction, alleviate and continue beating up to fell when the automatic reverse winding when braking stops.
Fell mobile device during starting is so-called recoiling device, when loom starts, makes and sees motor or coiling motor forward or reverse off, and fell is only moved set amount, to prevent to produce Mi Lu or thin road.The intervalization and the actuating quantity of action cycle numbering, action reason, dwell time have been set in order to carry out this action.
(invention effect)
In the present invention; Because when loom stops; The above-mentioned cycle numbering that repeats corresponding to pattern of opening figure and at least one of loom dwell time, and the combination of loom stop reason; Actuating quantity when preestablishing action non-action state and the action of the anti-locking apparatus of multiple shutdown weft bar; And set control according to these and shut down the anti-locking apparatus of weft bars, prevent function so the opening figure (weave) when loom stopped can be set optimal shutdown weft bar, and can suppress to shut down the generation of weft bar more reliably.In addition,, set,, can improve the Homes Using TV of loom with this shutdown platform number that makes the good and minimizing loom of weaving property so each of loom set to attach most importance to weaving property of raising owing to eliminate to shut down weft bar in possible trouble.That is, for example, when the Warp opening amount is big, or warp tension is when high; Because it is remarkable to shut down weft bar, in the past, has to dwindle respectively the Warp opening amount, or reduces warp tension ground and set; But in the present invention,, or increase warp tension even its setting strengthens the Warp opening amount respectively; Owing to can suppress to shut down the generation of weft bar, also can have good loom picking performance so can strengthen the Warp opening amount or increase the warp tension setting, can improve weaving property (the present invention 1).
In addition; In the present invention; Because the cycle numbering that repeats corresponding to pattern of opening figure and the combination of loom dwell time and loom stop reason; Actuating quantity when having set action non-action state and the action of the anti-locking apparatus of multiple shutdown weft bar is so can prevent to shut down weft bar (the present invention 2) for all cycle numbering, loom dwell time and loom stop reason effectively.
As kind of the anti-locking apparatus of shutdown weft bar; The rotating device because the sky that the picking when being provided with the fell mobile device that when loom starts, moves fell and carrying out not with starting is turned round beats up; And make stream oriented device corresponding to combinations thereof; So actuating quantity when preestablishing action non-action state and action is can corresponding effectively generation reason of shutting down weft bar.

Loom stop filling bands proventing method of the present invention; Be to be prerequisite with the looms 1 that constitute the opening figure that a pattern repeats by 3 of loom main shaft 23 more than the cycle; In the cycle numbering that a pattern of corresponding opening figure repeats and the dwell time of loom at least one, with the combination of loom stop reason; Actuating quantity when preestablishing multiple type action non-action state of shutting down the anti-locking apparatus 44 of weft bar (the fell mobile device 48 when sky beats up rotating device 45, the fell mobile device 47 when moment of torsion increases rotating device 46, motor braking, starting) and each device action; And according to these settings; When loom 1 running, 13 the shutdown weft bar of weaving cotton cloth that produces in order to prevent to follow stopping of loom 1, and the anti-locking apparatus 44 of weft bar is shut down in control.
As stated, repeating at a pattern is on 3 fabrics more than the cycle, the opening 8 of warp thread 2; Cycle during according to the stopping of loom 1; Be in and remain silent or open state, the mobile degree of the fell 11 that therefore produces because of warp tension, because of each cycle of a pattern repetition different.Therefore, being used to shut down the condition that weft bar prevents, is to set according to each cycle, by the condition enactment in each cycle, is to be used for bringing into play effectively the extremely important factor that weft bar prevents function of shutting down.
Fig. 4 shows be as instantiation with 6 cycles be the weave figure that a pattern repeats the opening figure of (pattern of weave repeats).In the running of loom 1, because the generation of stop reason or manually stop, and main control unit 30 is sent halt instruction; After loom 1 (loom main shaft 23) braking; It stops at and produces the stop signal or the next cycle in halt instruction cycle, and then this stops, and it automatically makes loom main shaft 23 reversings; After stopping, it stops Spindle rotation angle that (standby) stipulate, 320 ° of parts for example in the cycle that produces stop signal or halt instruction.In the weave of Fig. 4, when loom 1 stops, the opening 8 of warp thread 2, the 1st cycle, the 2nd cycle, the 4th cycle, the 5th cycle stop (standby) time, be in open state, the 3rd cycle, the 6th cycle stop (standby) time, be in the state of remaining silent.
In addition, according to the air-jet loom 1 that the applicant (Tsudakoma Corp) makes, the operational situation after its stop signal produces is described below.In the running of air-jet loom, when having produced stop reason, if Weft stop for example then locates to detect the Weft stop signal as stop signal for 290 ° in the anglec of rotation of loom main shaft 23.Former moving motor 24 is located to begin to accept braking 70 ° of the next cycle that produces Weft stop, warp stop motion and stop signal generating period, and is stopped in this cycle.The braking of following former moving motor 24 stops, loom main shaft 23, and the automatic reverse winding through former moving motor 24, and stop at 320 ° of cycle of producing stop signal and locate.When Weft stop, further locate, and bad weft yarn is extracted with 180 ° that manually are made to the generation Weft stop signal period; Then; Locate (beating up at sky, is 300 ° or 160 °), restart subsequently for 320 ° that are made to previous cycle of producing the Weft stop signal period again.When warp stop motion, 320 ° that produce the warp stop motion signal period locate to have repaired warp thread 2 after, intactly restart, but when free beating up, be made to 300 ° or 160 ° with its anglec of rotation.
The dwell time of loom 1; After under the situation of the embodiment 1 (table 1) that states; On sky beats up the fell mobile device 48 in rotating device 45 and when starting, be decided to be the interval of each device official hour length, and each intervally sets that action is failure to actuate and the actuating quantity when moving at these.To the sky rotating device 45 that beats up, the interval that is set at 0～2 minute, surpass 2 minutes interval.In addition, to the fell mobile device 48 in when starting, (determined 4 minutes actuating quantity of dwell time, actuating quantity is to set with the proportional calculating of the dwell time of instrumentation to be set to 0～4 minute interval.), surpass 4 minutes interval (actuating quantity is set to 4 minutes actuating quantity of dwell time).
In addition, stop reason has Weft stop, warp stop motion, and manually stops 3 kinds.Weft stop is to detect picking when bad at picking feeler 36, with 290 ° of outputs of the anglec of rotation of loom main shaft 23.In addition, warp stop motion results from menopause tablet 6 and detects when warp thread breaks or warp thread relaxes.In addition, manually stopping is for woven termination or experiment and operate stop button 34,35 and carry out by the operator.In addition, after among the embodiment 1 (table 1), embodiment 2 (table 2) and the embodiment 3 (table 3) that state, warp stop motion and manually stopping to be failure to actuate with the action of shutting down the anti-locking apparatus 44 of weft bar and the actuating quantity when moving is set at identical relatively.
Multiple shutdown weft bar is prevented locking apparatus 44; Constituting more than two in the fell mobile device 47 when beating up rotating device 45, moment of torsion increase rotating device 46, motor braking, the fell mobile device 48 when reaching starting by sky; But the above-mentioned cycle numbering that repeats corresponding to 1 pattern of opening figure and at least one of loom 1 dwell time, with the combination of the stop reason of loom 1, and set the state that these actions are failure to actuate.Therefore, the form of its combination is the combination of (1) cycle numbering and dwell time and stop reason, the combination of (2) cycle numbering and stop reason, the combination of (3) dwell time and stop reason, 3 kinds.These combinations are considered loom 1 stop conditions and are set.
In addition, dwelling period specified device 31 is used in when shutting down the condition enactment experiment that weft bar prevents.When the condition enactment experiment that the shutdown weft bar prevents, utilize setting apparatus 33 with the designated period numbering and after setting the dwelling period of 1 pattern repetition the operator, operation stop button 35 in the running of loom 1 is tested in order to shut down weft bar, with manually stopping loom 1.Former moving motor 24 by braking immediately, but be braked after the cycle of arrive setting (cycle numbering), and then braking stops automatic reverse winding, with this stop (standby) in the Spindle rotation angle of the regulation of appointment dwelling period for example 320 ° locate.Like this, in the condition enactment experiment of shutting down the anti-locking apparatus 44 of weft bar, can in the cycle of the hope that 1 pattern repeats, stop loom main shaft 23, and can easily carry out the condition enactment experiment with this.Below, be can utilize optimal condition enactment that condition enactment experiment obtains
