Description

Be used to start the method and apparatus of textile apparatus
Technical field
[0001] the present invention relates to be used to start the method and apparatus of textile apparatus.
Background technology
[0002] comprises that the textile apparatus that first CD-ROM drive motor that is used to drive loom and being used to drives second CD-ROM drive motor of shed-forming machine is known, for example WO 2004/092467A1.In this case, activate first CD-ROM drive motor and second CD-ROM drive motor by means of control and/or regulon.
[0003] by means of suitable driving method, can be at common instantaneous starting first CD-ROM drive motor and second CD-ROM drive motor connected.This allows good synchronism, and has avoided the idle period.Yet, if two motors are identical instantaneous being activated, the startup stage big electric current and/or energy supply must be arranged.
[0004] therefore, for example from JP 10-102356A as can be known, in order to start the CD-ROM drive motor of loom after the CD-ROM drive motor of shed-forming machine, the connection of shed-forming machine and loom is instantaneous to be inequality, but must separate each other.In this case, when only after starting shed-forming machine and loom, shed closed taking place, between shed-forming machine and loom, there is simultaneously operating.The shortcoming of this Method type is that loom can not operate optimisedly.
Summary of the invention
Therefore [0005] target of the present invention provides the method and apparatus that the optimization that is used for textile apparatus starts.
[0006] method by (particularly stopping the back) startup textile apparatus of having no progeny in weaving realizes this target, wherein control second CD-ROM drive motor that is used to drive first CD-ROM drive motor of loom and is used to drive the shed-forming machine by at least one control and/or regulon, described second CD-ROM drive motor connects that instant t 1 is activated and described first CD-ROM drive motor is connected instant t 2 second and is activated first, described control and/or regulon are set the weaving type of shed-forming machine, and determine that according to the weaving type of first parallel that is inserted into after starting second connects the instant t 2 and the first time difference Δ t that connects between the instant t 1, the startup kinematics of first and/or second CD-ROM drive motor and/or shed open preform.Therefore, compare with gratifying weaving type, under the not satisfied situation of weaving type of first parallel that is inserted into after the startup, the time difference that possible preform shed open and/or selection are bigger, littler startup acceleration and/or littler toggle speed.
[0007] in the context of the present invention, the weaving type refers to the type and the mode of shed-forming, and wherein for example the speed of the heald frame of quantity by being used for the heald frame that shed-forming moves and/or distribution, motion and/or the texture features of relevant warp are determined the type of weaving." gratifying weaving type " refers to the weaving type that has low energy demand and/or cause the gadget load in this article.For example " gratifying weaving type " is that only a spot of integrated box movement and/or the integrated box movement that is symmetrically distributed are so that only produce the shed-forming of little mechanical load.On the contrary, " not satisfied weaving type " can be understood that to represent the shed-forming that (for example also has big energy requirement so that drive heald frame) under big mechanical load.The structure that depends on shed-forming machine etc., because load and/or energy aspect, only heald frame, a plurality of heald frame or all integrated box movements can be gratifying.The textile apparatus of the parallel that startup will be inserted into for example also depends on the shed-forming that inserts during the last parallel before interruption.
[0008] in the context of the present invention " startup textile apparatus " refers to a kind of like this operation: can be activated to run well by means of this operation loom and shed-forming machine.In this case, second CD-ROM drive motor can at first be activated with low-speed running, and warp is brought into the desired location that parallel inserts by means of shed-forming machine (for example dobbies or jacquard attachment), that is to say to form required shed open.This motion of warp is called the shed open preform before the shed-forming machine startup.Only after warp was in desired location, the shed-forming machine just was activated to run well.In one embodiment, the shed-forming machine has coupling arrangement etc.After shed-forming device and/or warp have been brought into desired location, can disconnect the shed-forming device in this case, so that the motion of shed-forming machine is not passed to the shed-forming device.Therefore, can prevent or reduce at least to put on mechanical load on the shed-forming machine when the shed-forming machine accelerates to when running well by what the shed-forming device caused.Therefore also reduced energy consumption.After the shed-forming machine startup or side by side, loom is activated and parallel is inserted into.
[0009] particularly when relating to dobbies, for example can select the independent heald frame that is used to move and/or drive the shed-forming machine and do not have the additional movement of heald frame by starting corresponding connector.In this case, can drive shed-forming machine one-period or a plurality of cycle, and warp does not move in this case.For example in EP 0 851 045 A1 or EP 1 382725 A1, corresponding shed-forming machine has been described.Only also be activated with after running well when loom, connector etc. are activated and warp moves into and is used for the used weaving type of follow-up parallel.
[0010] alleged startup kinematics refers to by starting the startup campaign that acceleration and toggle speed are caused in the context of the present invention.Also can determine to start kinematics by the required torque that is applied in first CD-ROM drive motor or second CD-ROM drive motor.In one embodiment of the invention, the startup kinematics of first and/or second CD-ROM drive motor can suitably be adjusted to required kinematics.The measured value of for example use to need considering etc. is regulated.
[0011] start-up operation by making textile apparatus is fit to the weaving type of first parallel that will be inserted into, and textile apparatus can start at any weaving type optimisedly.Avoid big time difference in this case as far as possible, because the big start delay of the preformed delay of shed open and/or first CD-ROM drive motor and/or second CD-ROM drive motor, so that prevent that textile apparatus has the long idle period and so that avoids fabric defect between the starting period.
[0012] in one embodiment of the invention, have in the required weaving type of first parallel that will be inserted under the situation of big energy requirement and/or big mechanical load, the shed-forming machine is driven the one-period of shed-forming machine or a plurality of cycle so that form the shed open with gratifying weaving type, wherein this gratifying weaving type is compared with required weaving type and is had littler energy requirement and/or littler mechanical load, and first CD-ROM drive motor is activated as follows: first parallel insertion and/or first only takes place after the weaving type that the shed-forming machine inserts according to first parallel is driven beat up.For example the such shed-forming machine of dobbies begins rotation by CD-ROM drive motor, and for example the shed-forming device of heald frame and so on for example moves and moves so that form corresponding shed open according to required textile design.Compare with the startup of weaving type unsatisfactory, can use still less energy consumption to quicken or start the shed-forming machine for gratifying weaving type, for example, at first can only drive some shed-forming devices, and residue shed-forming device is only in motion subsequently, so that form the shed open of first parallel that will be inserted into.Because do not depend on required weaving type and start the shed-forming machine, so that form the shed open of gratifying weaving type, so that the energy between the starting period consumes is less.Also instantaneous after a while/or start first CD-ROM drive motor according to corresponding startup kinematics do not insert so that parallel does not take place during the shed-forming of corresponding required pattern in the weaving type.In this case, the weaving type when first parallel is inserted into can depart from required weaving type, if be not all to move immediately according to required weaving type heald frame for example, forms required shed open but heald frame one after the other moves.
[0013] in one embodiment, the weaving type of coupling first parallel that will be inserted into progressively takes place.Therefore, for example, suppose that the last parallel that is inserted into is 2/6 weavy grain, in the time of can expecting that then first parallel that will be inserted into is 7/1 weavy grain after interrupting, initial activation shed-forming machine is so that be that 4/4 weavy grain forms shed open and be that 5/3 weavy grain forms shed open in second round, and only activates the shed-forming machine when the period 3 so that be that 7/1 weavy grain that first parallel inserts forms shed open.
[0014] in another embodiment of the present invention, time difference Δ t is configured to make that the relevant difference in the synchronization point angle position is in the range of tolerable variance at least.Under optimal conditions, the difference of angle position is zero.Yet in fact relatively little deviation almost is inevitably and is acceptable.A for example weaving cycle or a plurality of weaving cycle of loom after the shed-forming machine starts in this case.By means of such time difference, in specific embodiment, can realize the simple synchronization of shed-forming machine and loom from required instantaneous beginning.
[0015] in one embodiment of the invention, shed-forming machine and loom are from instant t 3 run-in synchronism in fact.Mean occurring in synchronously in the range of tolerable variance that is set of motion in the context of the present invention in fact synchronously, this allows fluctuation synchronously during the weaving cycle.In this case, shed-forming machine and loom begin that synchronous operated instant t 3 can to connect instant t 2 consistent with second of first CD-ROM drive motor that is used to drive loom.In other embodiments, synchronous operated instant t 3 can be positioned at after the second connection instant t 2.
[0016] in one embodiment of the invention, from instant t 3 beginning shed-forming machines and loom in fact run-in synchronism to the virtual synchronous axis.In this case, by virtue of the fact that the special angle position in the weaving cycle only need shed-forming machine and loom synchronously.In this case, preferably realize the virtual synchronous axis by means of control and/or regulon.For example can learn the virtual synchronous axis from WO 2004/092467.
[0017] in another embodiment of the present invention, use moment of torsion to activate first CD-ROM drive motor and/or second CD-ROM drive motor, wherein this moment of torsion is determined according to actual rotary speed and/or actual angle position.Such motor can turn round with macro-energy efficient, that is to say that it only has inapparent energy loss.In this case, determine required torque in advance at concrete actual rotary speed and/or actual angle position, and this required torque is stored in the storage device.In this case, required torque can depend on other parameters, for example fabric type etc.
[0018] in another embodiment of the present invention, activate the shed-forming machine as follows: connecting instant t 2 is that the moment of torsion of the second CD-ROM drive motor transmission is minimized.Therefore, starting the instantaneous of loom, for loom, there are enough utilisable energies.In this case, for example by means of suitable shed-forming, can minimize the moment of torsion that will be delivered to the shed-forming machine.
[0019] in one embodiment of the invention, at the shed open preform shed-forming machine that turns round as follows: instantaneous not all in the connection of first and/or second CD-ROM drive motor, more specifically there is not the motion of shed-forming device.In one embodiment, for this purpose, at first with low-speed running shed-forming machine, warp is brought into the desired location of the parallel that will be inserted into.After warp is in place, heald frame disconnect with the shed-forming machine connect and the shed-forming machine is activated with normal operation.Because heald frame is disconnected connection, so reduced in normal operation, to start the necessary moment of torsion of shed-forming machine in this case.In another embodiment, consider the last parallel that is inserted into, the shed-forming device can be maintained in its position.Therefore, when CD-ROM drive motor is activated, do not have shed-forming device motion so that reduce load, even instantaneous in the connection of associated drives motor also be like this.In another embodiment, the CD-ROM drive motor of shed-forming machine is activated, and the shed-forming device disconnects and the connecting and only be connected in the shed-forming machine after motor quickens so that the formation shed open of shed-forming machine.
[0020] in addition, by means of in the equipment that starts textile apparatus of having no progeny realize described target, second CD-ROM drive motor that described textile apparatus comprises loom, shed-forming machine, is used to drive first CD-ROM drive motor of loom and is used to drive the shed-forming machine.Equipment according to the present invention has at least one control and/or regulon so that control first CD-ROM drive motor and second CD-ROM drive motor, and this unit comprises following device: can connect instant t 2 and first and connect the time difference Δ t between the instant t 1, the startup kinematics and/or the shed open preform of first and/or second CD-ROM drive motor according to set second in the weaving type of first parallel that will be inserted into after the startup by this device.The result, for example under the situation of " weaving type unsatisfactory " with macro-energy demand, compare with gratifying weaving type, can determine bigger time difference, littler startup acceleration and/or littler toggle speed with little energy requirement.
[0021] in one embodiment of the invention, the shed-forming machine comprises the device of the selectivity motion that is used for warp, particularly comprises the coupling device that is used to connect or disconnects heald frame etc.

The specific embodiment
[0024] Fig. 1 shows the equipment that is used to start the textile apparatus that comprises loom 1 and shed-forming machine 2 with illustrating.Textile apparatus comprises first CD-ROM drive motor 10 and second CD-ROM drive motor 20, wherein first CD-ROM drive motor 10 driving shaft 12, the second CD-ROM drive motors 20 that drive slay 13 via gear stage 11 drive via gear stage 21 and are designed to for example shed-forming machine 2 of dobbies.Shed-forming machine 2 comprises the axle 22 that is connected to the heald frame (not shown) via connecting rod 23.Connecting rod 23 is lain in axle 22 and/or heald frame is lain in connecting rod 23 for example comprise coupling device, can select discrete heald frame by this coupling device.Therefore then the motion of axle 22 only can be delivered to discrete heald frame if desired or not be delivered to heald frame or be delivered to all heald frames.
[0025] is used for according to the present invention for example comprising the control module 3 that is used to control first CD-ROM drive motor 10 and second CD-ROM drive motor 20 at the equipment that starts textile apparatus of having no progeny.From the signal of anglec of rotation encoder 4 with from the signal of anglec of rotation encoder 5, wherein anglec of rotation encoder 4 is coupled to driving shaft 12 to control module 3 input, and anglec of rotation encoder 5 detects the position of the axle 22 of shed-forming machines 2.In other embodiments of the invention, by dividing other control and/or regulon, for example by means of last level controller starter 10,20 synchronously.CD- ROM drive motor 10,20 can with master/slave or from/from mode operation.Additionally or alternatively, on CD- ROM drive motor 10,20, provide anglec of rotation encoder 6,7.
[0026] in addition, control module 3 is set the series-shed pattern that is used to form the parallel that will be inserted into for shed-forming machine 2.For example the shed open by will being formed, the speed when shed open is formed and/or the parallel type that will be inserted into are determined the weaving type.Select the heald frame (not shown) according to the weaving type, and form corresponding shed open.
[0027] in Fig. 1 by a dotted line arrow 24 n-lustrative show and be used for heald frame is connected in axle 22 control action, for example be used for discrete warp and/or heald frame the selectivity motion control action or be used for the control action of the motion of a plurality of warps and/or heald frame.Show the actuating of CD- ROM drive motor 10,20 by the solid arrow n-lustrative.Series-shedly determined weavy grain.If if only have some warps and/or heald frame to move so as to form shed open and/or when shed open is formed warp and/or heald frame will slowly move, then mechanical load and/or energy requirement are lower usually.In the context of the present invention, under these situations, be called " gratifying weaving type ".
[0028] after interrupting, restarts CD- ROM drive motor 10,20, connect instant t 1 first and start second CD-ROM drive motor and connect instant t 2 startups first CD-ROM drive motor second by means of control module 3.Control module 3 comprises unshowned device, by this device according in the have no progeny weaving type of first parallel that will be inserted into, single heald frame can move so that form pre-shed open and/or the time difference Δ t (Δ t=t2-t1) between the connection instant t 1 of the connection instant t 2 of first CD-ROM drive motor and second CD-ROM drive motor can be set for more than or equal to zero, and/or can set the startup kinematics of first CD-ROM drive motor 10 and/or second CD-ROM drive motor 20.The startup kinematics of the time difference Δ t and/or first CD-ROM drive motor 10 and/or second CD-ROM drive motor 20 is configured in this case, in the middle of have no progeny first parallel that will be inserted into when having not satisfied weaving type, compare with gratifying weaving type, select bigger time difference Δ t, littler startup acceleration and/or littler toggle speed.
[0029] Fig. 2 to Figure 11 shows the start-up operation according to the textile apparatus of various exemplary embodiments of the present invention in Fig. 1.In this case, show the curve movement wm of the slay of loom with respect to time axis t n-lustrative by solid line.Shed-forming machine 2 shown in Fig. 1 for example is dobbies and/or jacquard machine, and comprise for example various shed-forming device of heald frame, in Fig. 2 to Figure 11, show curve movement up to four shed-forming device f1-f4 with respect to time axis t n-lustrative.In this case, show the curve movement of the first shed-forming device f1, the curve movement of the second shed-forming device f2 is shown, and the curve movement of shed-forming device f3 is shown by short tracing by point curve by solid-line curve.
[0030] Fig. 2 n-lustrative shows in first exemplary embodiment after interrupting the start-up operation according to the textile apparatus of Fig. 1.In this case, the required weaving type that fabric is woven first parallel that wherein will be inserted into is not satisfied, that is to say in the formed shed open of first parallel that will be inserted into of having no progeny be not satisfied, for example this is because must move all shed-forming devices so that form shed open.In exemplary embodiment, connect instant t 1 first and start second CD-ROM drive motor 20 that is used to drive the shed-forming machine 2 shown in Fig. 1 according to Fig. 2.In the method according to the invention, consider the not satisfied weaving type of first parallel that will be inserted into, select time difference Δ t greater than zero, and at the instantaneous starting of t2=t1+ Δ t according to first CD-ROM drive motor 10 that is used to drive loom 1 shown in Figure 1.In this case, in described exemplary embodiment, do not have to postpone and start shed-forming machine 2 with the speed that runs well.In this case, only the first weaving cycle c of shed-forming machine 2 runnings has occupied and the as many time in follow-up weaving cycle exactly.In other embodiments, the duration that lasts longer than the follow-up weaving cycle of the slow start shed-forming machine 2 and the first weaving cycle c.In first exemplary embodiment shown in Figure 2, time difference Δ t is corresponding to the time of weaving cycle c.Certainly expect other time difference.Particularly, when the first weaving cycle c had occupied than longer time in the cycle of weaving subsequently, time difference Δ t can be selected as making that the angle position is synchronous at least one some place under additional situation about measuring.
[0031] because the startup of shed-forming machine and loom start between life period difference Δ t, so can avoid overlapping between the starting current of loom and shed-forming machine.In described exemplary embodiment, at instant t 2 startup looms 1 and not about starting kinematic further action, and the instant t 2 that starts the CD-ROM drive motor 10 of loom 1 also is an instant t 3, make according to loom shown in Figure 11 and 2 run-in synchronisms of shed-forming machine from this instant t 3, that is to say loom 1 and shed-forming machine 2 in tolerance in fact by driven in synchronism.
[0032] avoid having not satisfied required weaving type simultaneously for the required shed open that forms first parallel that will be inserted between the starting period, shed-forming device f2, f3 move in the same manner in exemplary embodiment shown in Figure 2.In order further to reduce the load of shed-forming machine between 2 starting periods shown in Fig. 1, drive shed-forming machine 2 so that form shed open according to gratifying weaving type instantaneous 1 in exemplary embodiment shown in Figure 2, the curve movement of the 3rd shed-forming device f3 (movement profile) is identical with the curve movement of the first shed-forming device f1 under the situation of gratifying weaving type in the exemplary embodiment.Because forming startup shed-forming machine 2 under the situation of shed open according to the gratifying weaving type relevant with required weaving type, thus the startup stage in required electric current supply and/or energy supply be lowered.Shed-forming device f3 remains on its primary importance at first, and for example Guan Lian heald frame disconnects with axle 22.Therefore, when when instant t 2 starts CD-ROM drive motor 10, only shed-forming device f1, f2 motion is so that form the shed open of first parallel that will be inserted into.Only the startup stage after select the shed-forming device and drive shed-forming machine 2 according to the used weaving type of fabric so that form corresponding shed open for follow-up parallel inserts.By what connect that time difference Δ t between instant t 1, the t2 realizes be: only form first parallel produce after inserting required shed open the parallel insertion also/or carry out slay and beat up.
[0033] Fig. 3 shows the method that is used to start in second exemplary embodiment of the present invention according to textile apparatus shown in Figure 1.In this case, when identical instant t 1=t2, start according to first CD-ROM drive motor 10 shown in Figure 1 and second CD-ROM drive motor 20.In second exemplary embodiment, corresponding to activate second CD-ROM drive motor 20 according to method shown in Figure 2, that is to say, during the period 1 of shed-forming machine 2 c, activate second CD-ROM drive motor 20 as follows: for gratifying weaving type forms shed open (curve movement of the 3rd shed-forming device f3 is corresponding to the curve movement of the first shed-forming device f1).Only after the first weaving cycle, drive shed-forming machine 2, so that form required shed open (curve movement of the 3rd shed-forming device f3 is corresponding to the curve movement of the second shed-forming device f2).Shed-forming device f3 is interim in this case disconnects with axle 22.At the instant t 2 that starts CD-ROM drive motor 10, all shown shed-forming device f1 to f3 move.
[0034] in this case, activate first CD-ROM drive motor 10 that drives loom 1 according to shown in Figure 1 being used to less startup acceleration.Therefore, only producing first of parallel insertion and/or reed (not shown) in the cycle subsequently at the first weaving cycle c beats up.In addition, consider the little startup acceleration of first CD-ROM drive motor, loom the startup stage in energy requirement keep less.Only begin to provide the synchronous of loom 1 and shed-forming machine 2 in this case from instant t 3.In this case, in the exemplary embodiment, the duration of the first weaving cycle c is same as the duration in follow-up weaving cycle.Similarly, can expect other duration.
[0035] Fig. 4 shows another exemplary embodiment that is used to start according to the present invention according to the method for textile apparatus shown in Figure 1.The connection instant t 2 of first CD-ROM drive motor 10 has been offset the amount of a time difference Δ t after the connection instant t 1 of the second connection motor 20, this time difference Δ t is corresponding to the duration of weaving cycle c in the exemplary embodiment.Second CD-ROM drive motor 20 activated as follows: do not have the shed-forming device to be moved by shed-forming machine 2 when the connection instant t 2 of loom.And in fact, shed-forming device f1-f3 at first moves so that form shed open at first parallel that will be inserted into after starting, and shed-forming device f1-f3 disconnects with axle 22 afterwards.Like this, second CD-ROM drive motor 20 only needs low-down energy supply when the connection instant t 2 of first CD-ROM drive motor 10.Therefore can be minimized in energy and/or current drain when connecting instant t 2.From connecting instant t 2, shed-forming machine 2 and loom 1 run-in synchronism.Therefore, the connection instant t 2 of first CD-ROM drive motor 10 also is to begin to provide this synchronous operated instant t 3.
[0036] Fig. 5 shows the method that is used to start according to textile apparatus shown in Figure 1 in the 4th exemplary embodiment of the present invention.Control module 3 shown in Fig. 1 has been set the gratifying required weaving type of the shed-forming machine 2 that is used for the 4th embodiment.In this case, for gratifying required weaving type, the electric current and/or the energy requirement that are used to activate second CD-ROM drive motor 20 of shed-forming machine 2 are quite little, so as first CD-ROM drive motor and second CD-ROM drive motor when instant t 1=t2, start and be possible be the startup stage in without any postpone or analogue under activate first CD-ROM drive motor.The startup of two CD- ROM drive motors 10,20 also provides run-in synchronism.Therefore instant t 3 is same as and connects instant t 1=t2=t3.
