Description
Technical field
The present invention relates to a kind of particularly method of ring spinner of spinning machine that is used to control, described spinning machine has drafting system, is used to receive the spindle of spool, ring ingot ring rail and/or step rail and the fixture that is used for yarn, wherein said drafting system, spindle, ring ingot ring rail and/or step rail by machine controller through relevant driver on-stream maintenance coordinate.
Background technology
European patent EP 0 462 467 A1 specifications disclose a kind of as the described spinning machine of technical field part.Described fixture is the clamping device that is in the cop below that is arranged on the spindle, and described clamping device has been realized using short length of yarn just can handle underwinding (Unterwindung).
In the ring spinner with yarn fixture, no matter described yarn fixture is underwinding or clamping device, and each operating parameter of spinning machine all must accurately mate each other.May in intact process (abspinnen) (downwards around rotation), suitably influence the characteristic of yarn in spinning, so that guarantee the operation of fault-free ground.On the one hand, should avoid spun, tube changng operation and spinning connect again in (anspinnen) process and break.On the other hand, with regard to the tube changng operation, can tear or cut off yarn, where necessary by on fixture, using corresponding auxiliary equipment (for example cutter sweep, tear blade etc.).This is particularly suitable for the yarn of high-tenacity or deep drawing quality.Must be at this by changing the ultimate tensile strength that yarn twist and fineness of yarn come the appropriate change yarn.
German patent specification DE100 37 513 A1 have disclosed in having spun process the separately control of rotating speed to the rotating speed of spindle or drafting system, make it to meet requirement to underwinding or clamping thereby changed fineness of yarn and yarn twist.
German patent specification DE 10 2,006 003941 A1 have described the influence of spinning program, wherein change the spinning program as follows, promptly under the situation of considering instantaneous working condition, by standard spinning program the drafting force of rotating speed and/or fiber band is departed from from default value, so that obtain very high particularly continuity production of operational reliability.
Current, significant around intact process still as needing the employee that weaves in the past, the weaving employee must oneself adjusting around intact operation the best.The operator must have comprehensive knowledge and rich experiences for this reason, and wants the intact process of opposing connection to carry out different adjustment for different spinning programs.Thus, what for example will process is cotton textiles or the mixture of being made up of cotton and chemical fibre, and whether the spinning program provides spun yarn, rove, standard yarn or even effect yarn, and this all can produce greatest differences.In addition, the operator also must have actual machine relevant knowledge is set, and particularly operates the spinning program and described spinning program when being in the limit range that disposes described spinning machine as the operator.This has prevented that spinning parameters around intact process from becoming in the scope that is not allowed to that machine is not provided with at first.
Summary of the invention
Therefore, the objective of the invention is to propose a kind of high autocontrol method, this method has been eliminated above-mentioned defective, has been had very high operational reliability and production capacity, though that is to say in spinning finishes process, also make the broken string the least possible.
Above-mentioned purpose realizes in the following manner, the a plurality of tube changng programs of storage in machine controller, machine controller or operator choose suitable tube changng program by input block from described a plurality of tube changng programs, described tube changng program depends on:
-spinning material and/or
-spinning type or yarn property and/or
-spinning fineness (Ne, N
m, tex) and/or
-yarn twist (α) and/or
-machines configurations,
Wherein, with regard to the yarn that is obtained according to the spinning program, tube changng program directionality ground in the tube changng process changes yarn property, changes especially yarn strength of yarn property that process and/or spinning subsequently connect the process optimum Match so that obtain with finish process, spool of spinning.
Described tube changng program preferably includes finish program and/or spinning of the spinning relevant with tube changng and connects program.The tube changng program can comprise one or two in above-mentioned two programs.The tube changng process can comprise that the program that finishes of spinning, spool are changed operation and/or spinning subsequently connects process.
The tube changng program also can comprise the prerun program of describing as among the DE-B-195 16 091.This prerun program is being controlled ring spinner from finishing tube changng to the time period that spinning starts.By the prerun program, yarn is placed or is clamped in the underwinding of spindle, and the fine rule supported that forms by the steel traveler on the ring rail is on the circumference of spindle.The difference of this method is, starting spindle fast so that production makes new advances yarn count (package) before on the new bobbin of installing, spindle is with the normal direction of rotation rotation of the slow-speed of revolution along spindle, the speed that spindle rotatablely moves and the duration of described running are selected like this, make the steel traveler on the ring rail be set at the back along the spindle direction of rotation of yarn continuity point on the spindle circumference.At the latest when low speed rotation stops, steel traveler enters in the required obliquity of the new bobbin of fast winding subsequently.With reference to above-mentioned patent specification the present invention is done further technology statement.
The prerun program also can comprise yarn parameter, for example the initial raw material of fineness of yarn, fiber or yarn property.The prerun program can with spun that program and/or the spinning program of connecting combine or carried out as independent program.
The selection of tube changng program means that also machine controller itself is combined into the tube changng program from the program stored module.This for example can realize by the selection of module.
Particularly when the highest winding position of ring rail from spool is moved down into the underwinding position of spool below, pipe pushes up coiling (Oberwindung) to the tube changng program and/or rewinding starts around (Hinterwindung) by carrying out when particularly incidental looping finishes at spool.
Best yarn strength is reeled and underwinding operation particular importance for the pipe top that spinning finishes in the process, and in tearing line operation or secant operation, spool replacing doff and the spinning of back connects the process particular importance.
According to preferred implementation, via automatically selecting suitable tube changng program and automatically start the tube changng program at given time in a plurality of tube changng programs of option program from be stored in machine controller, described condition is machine controller according to following condition:
-spinning material and/or
-spinning type or yarn property and/or
-spinning fineness (Ne, N
m, tex) and/or
-yarn twist (α) and/or
-machines configurations.
The program of advantageously spinning is stored in the machine controller.But, also can before being about to carry out spinning process, a spinning program or a plurality of spinning program be read in the machine controller.The user can be by the definite spinning program that needs of input block.Therefore by choosing suitable tube changng program and automatically carry out described suitable tube changng program at given time point in a plurality of tube changng programs of selection routine from be stored in machine controller, described option program equally preferably is stored in the machine controller machine controller according to selected spinning program, machines configurations and other standard.
In addition, the operator also can manually select.And machine controller can be operator's suggestion or selects best tube changng program.The operator can confirm described suggestion or make a choice or refuse to select.
For example, the operator also can select another tube changng program, or individually changes the special parameter of recommended procedure, for example fineness of yarn or yarn twist.Therefore, if need depart from instruction for special reason, the operator can oneself import fineness of yarn and/or the yarn twist that needs in the spinning process.
Then, in the given moment, machine controller automatically starts the tube changng program of choosing.And machine controller can be arranged so that the operator must manually start the tube changng process or manually call the tube changng program, for example by approving the request of spinning machine.
The operator also can manually import the parameter of spinning program in advance and it is stored in the machine controller by input block.This spinning program can be read electronically in advance and be stored in the machine controller by input block by (moving) data medium.
The spinning program can comprise multiple parameter.Therefore, for example fineness of yarn (Ne, Nm, tex), yarn variety (for example monochromatic yarn, colour-changeable yarn such as knot yarn, fancy yarns such as crape or the like) and yarn twist (α).Other parameter can by the raw material that uses for example natural fiber, synthetic fiber, inorfil, blended fiber etc. such as cotton thread limit.And, the pipe range of use and caliber, the kind of cop size that needs or diameter, ring rail and/or the diameter of ring rail can be used as spinning parameters and limit.
Machines configurations comprises for example ring rail diameter, steel traveler weight, the physical dimension of drafting system or boosting of drafting system, and described boosting determined the higher limit and the lower limit of roller rotating speed.In the selection of tube changng program, consider machines configurations, this has for example guaranteed the running individually in the predetermined range of speeds of being boosted by the drafting system that uses of drafting system roller, and by the variation that changes in the tube changng process delivered length in the spinning process particularly or tensile force the rotating speed of drafting system roller can be displaced in the range of speeds that is not allowed to.
In addition, machines configurations also can comprise the transport that is used for the full packages yarn.Therefore, whether the full packages yarn is transported to collecting box, perhaps whether on so-called fixed disk, the full packages yarn is directly offered up-coiler by linked set by the cop gathering-device, this may with rewinding around execution relevant.If spinning machine comprises the cop gathering-device, so preferred produce the very little rewinding of a large amount of winding angles around, make the rewinding that is collected in the cop in the collecting box around because mutual friction and can not separating.On the contrary, under the situation of jockey, cop is transported to the station of reeling separately by transfer dish.Because do not apply big mechanical stress on the surface of cop, so the rewinding of the winding angle steep than having of peanut is around being enough.
From the spinning program of choosing, calculate the driver that is used for drawing apparatus driver, spindle driver and ring rail driver by computing unit by machine controller, be stored in when needed in the memory in the machine controller for example, or under the situation of driver, be stored in the memory in the frequency converter.
This is equally applicable to the tube changng program, and handle or the driver of a drawing apparatus driver of the program that finishes of spinning or a plurality of drawing apparatus driver, a spindle driver or a plurality of spindle driver and ring rail driver provides basic by tube changng in order to be used for when yarn object is reeled end by machine controller calculating for described tube changng program.In addition, these drivers have been determined fineness of yarn, yarn types and the yarn twist that the tube changng process is particularly spinned and produced in the stage of finishing.
According to the yarn that will produce, can draw different pieces of information during driver in calculating the tube changng process.The tube changng program calculates the data of driver, make because the limitation of textile technology and in final stage or tube changng process that yarn object forms, particularly spun, doffed or changes spool and the process that connects again of spinning in the broken string that produces the least possible.In addition, tube changng program and the spinning program that finishes have also been guaranteed the variation of yarn property, make can clamp best or underwinding yarn and separation or cut-out in the process of changing spool.
Ring spinner can be worked in the scope of Ne (English count) 10-100 at for example fineness of yarn.This fineness of yarn scope for example can be divided into Ne10-20, Ne21-50, Ne51-70 and Ne71-100 subrange.For each fineness of yarn scope, can store one or more tube changng programs of coordinating mutually with these fineness of yarn scopes.Therefore, for example the tube changng program of Ne21-50 can be based on medium fineness of yarn Ne35 for example for the particular fineness scope.That is to say that described tube changng program is designed to for example yarn of Ne35 of medium fineness.Because it is too many that the fineness of yarn in the described fineness of yarn scope can not depart from medium fineness of yarn, so the tube changng program of medium fineness of yarn is applicable to other yarn in this yarn scope.Therefore, do not need to set independent tube changng program for every kind of fineness of yarn.Same method also is applicable to yarn twist.
For example raw material, yarn twist, yarn types and machines configurations etc. all take in if to spinning parameters, so final only remaining unique suitable tube changng program, described tube changng program is determined by selecting routine based on above-mentioned choice criteria by machine controller.This selection routine can be a software program, carries out respective algorithms and select only tube changng program according to above-mentioned parameter in described software program.
In addition, the characteristics that are provided for the tube changng program of fineness of yarn scope Ne10-20 (just being used for than coarse yarn) are, by increase that total draft increases fineness of yarn or by the coupling twist so that can tear described powerful yarn.The tube changng program that is used for fineness of yarn scope Ne71-100 (being used for fine yarn) reduces the fineness of yarn in tube changng stage by the total draft that reduces the tube changng stage, thereby preventing that fine yarn is too fast tears.
Therefore, the yarn speciality in the tube changng routine change tube changng stage (particularly spinning finishes the stage).Described change preferably obtains by changing fineness of yarn and/or yarn twist.The variation of fineness of yarn for example obtains by changing total draft.The variation of yarn twist can obtain by the conveying that changes yarn.Can control the conveying of yarn in the mode identical with the control drafting force by the rotating speed of drafting system roller.
Therefore, can from particular moment by tube changng program or spinning the finish twist or the twist multiplier (α) of routine change yarn, make in taking off the process of spool in clamping device and zone, underwinding hat top, to have the insertion that helps yarn as far as possible, the condition that clamps or tear or cut off.Wherein the twist of yarn should be not excessive, so yarn has best tearing or the cut-out ability.On the other hand, the twist of yarn can not be too small, thus yarn in spinning finishes process or the spinning after changing spool can not torn in restarting by accident.
Therefore, can reduce the brute force of yarn in the spinning stage that finishes by above-mentioned measure, and the corresponding measure by the drafting force and/or the twist increases yarn strength after tube changng.
Preferably will be transported to according to the corresponding controlling value of tube changng program on the driver or associated transducer of drafting system, spindle and ring rail etc. before the tube changng process of reality, make at the latest rewinding around constantly or rewinding walk around to produce in the journey and have the tube changng characteristic, the particularly spinning that the need yarn of characteristic that finishes.This relevant parametersization by the frequency converter of described driver realizes.In this case, the required controlling value of tube changng process makes controller work, for example with regard to drafting system, and the rotating speed of described controlling value counter extensioin device roller and then to carrying and total draft has corresponding influence.
Therefore, when spool reel to finish, preferably start the tube changng program by machine controller before beginning is reeled in the centre or during beginning.Yet, also can rewinding around after call the tube changng program.Therefore, the spinning unit with spindle, drafting system and ring rail or step rail or linkage driver is preferably when rewinding gets around the beginning or when being about to begin or begin to carry out the parametrization of tube changng when ring rail arrives " spool is yarn completely " position (at rewinding around before).
Fixture can comprise underwinding and/or clamping device.Under the situation of underwinding device, yarn is reeled and need not be clamped and keep around rough surface particularly.Under the situation of clamping device, yarn is clamped firmly, and in this case, yarn also can appear in the clamping device with the form that underwinding, particularly part are reeled.
The yarn fixture preferably promptly is arranged on the following position of spool on the interior spindle of ring spinner especially.In spinning finished process, ring rail was moved down into the height of fixture from its highest winding point, with provide rewinding around.In the moving downward of ring rail, the transporting velocity in the drafting system and the rotating speed of spindle are collaborative to be reduced, and makes at first to obtain the yarn twist and the fineness of yarn that need, and fine rule is advanced on spool in steep as far as possible mode.But, the tube changng program can change drafting system and walk around conveying or drawing-off in the journey at rewinding, feasible generation has the yarn of different yarns fineness, thereby before the underwinding, among and afterwards, particularly the dismounting of spool, together with the tear fracture of the yarn of association and the spinning processing after doffing restart in the less fault of generation.
Under the situation of fixture, ring rail rests on that extreme lower position continues that spindle circles or week how.Under the situation of clamping device, preferably ring rail only stops to yarn along circumferential length half to 3/4ths or place and clamp less than the circumferential length of wrapping range.Subsequently, ring rail is elevated to the above position of fixture again, and drafting system or drawing apparatus driver are stopped, and spindle driver is stopped, and both are stopped simultaneously.After underwinding, drafting system can still keep turning round a bit of time, with the by-carriage length of yarn.
In a kind of special embodiment of the present invention, after finishing cop production, the tube changng program should make the decrease speed of ring rail between pipe top coiling and underwinding change with respect to the rotating speed of spindle and/or the transporting velocity of drafting system, make the rewinding of putting 0.5 to 5 circle on the spool upper berth around, promptly yarn around.And after drawing apparatus driver stopped, the tube changng program can allow spindle to continue a bit of time of rotation, or stops simultaneously with drafting system.
Underwinding top or cut ring are fixed and are fixed on the spindle of clamping device top, and clamping device is transferable along spindle, and wherein device is provided with like this, and clamping device is leaned against on the underwinding top when the clamped position of yarn.Described clamping device is by spring upwards extruding from the bottom of spindle, and can be by independent actuating device in the process that ring rail moves downward or directly by ring rail clamping device is moved into extreme lower position (enable possition just).
In the production than coarse yarn, the tube changng program particularly influences drafting system by increasing total draft, produces fine yarn to be implemented in the unwinding stage.For example, the rotating speed of the delivery roller (conveying roller) by increasing drafting system and/or the rotating speed that reduces the input roller (feeding roller) of drafting system are realized the higher drawing-off of feeding fibrous material.
Correspondingly, in the production than fine yarn, target is preferably at the rotating speed of the delivery roller of tube changng stage by reducing drafting system and/or improve the rotating speed of the input roller of drafting system, makes the fibrous material of feeding have lower total draft.
Has twist multiplier α
1The production of yarn of predetermined fineness of yarn in, the tube changng program can increase the twist or be reduced to another twist multiplier α
2, the breaking load of yarn is at twist multiplier α
2Reach optimum value.
For example, rewinding around with underwinding in, the tube changng program can allow the fiber synthetic having the extra twist in the production through compiling yarn, and can reduce yarn twist in crape production.
In a kind of special embodiment of the present invention, around, underwinding and/or in service fast, the tube changng program should be eligible at rewinding
Wherein T=twist number, m=unit length, α
m=twist multiplier, N
m=fineness of yarn.N=spindle rotating speed (rev/min), L=fed distance (rice/minute).The variation of fed distance L determines that by time or rotational speed N the rotational speed N or the fed distance L of recoil or underwinding calculate according to described formula.
According to arbitrary described method in the claim 1 to 15, rewinding when the coiling of spool finishes around in, the tube changng program can be operated by machine controller, makes spindle with respect to the theoretical spindle rotational speed N that calculates along with the time drives with the rotational speed N that reduces or increase (t).
According to arbitrary described or in the claim 1 to 15 according to the method for above-mentioned embodiment, particularly in production through compiling yarn, the tube changng program can allow the fiber synthetic rewinding around and/or underwinding before or among have the extra twist.
According to arbitrary described or in the claim 1 to 15 according to the method for above-mentioned embodiment, particularly in production through compiling yarn or composite yarn, the tube changng program can rewinding around and/or underwinding before or among reduce yarn twist.
According to arbitrary described or in the claim 1 to 15 according to the method for above-mentioned distortion, in the production of fancy yarn or spinning linen thread (Siro), the tube changng program rewinding around and/or underwinding before or among the rotating speed of drafting system or fed distance L are remained unchanged, thereby finish and/or the stage of restarting of spinning produces the monochromatic yarn of no pattern in spinning.
According to arbitrary described or in the claim 1 to 15 according to the method for above-mentioned distortion, after finishing spool, the tube changng program rotating speed and/or the transporting velocity in the drafting system of spindle relatively changes the decrease speed of ring rail between pipe top coiling and underwinding, make on spool to lay to be less than 1 circle, preferably the rewinding of 0.5 to 0.75 circle around.
According to arbitrary described or according to the method for above-mentioned embodiment, after drawing apparatus driver stopped, the tube changng program can still make spindle continue a bit of time of rotation or drafting system stops simultaneously in the claim 1 to 15.
And, rewinding that the coiling of spool finishes around in, the tube changng program controller of can operating machines, spindle rotational speed N (t) operation that the spindle rotational speed N that makes spindle during this period of time calculate with relative theory is littler or bigger.
At for example colour-changeable yarn, in the production of fancy yarns such as knot yarn, the tube changng program at the latest from rewinding around time point begin to make the rotating speed of drafting system or fed distance L to remain unchanged, thereby particularly finish in the tube changng stage, underwinding and clamping stage obtain the not monochromatic yarn of wounded in the battle formula in spinning.
Particularly connect in the stage again with spinning in the tube changng stage in the spinning stage that finishes, the tube changng program can influence the driver of each driver, this is not only in order to change fineness of yarn and rotating speed, also the others for spinning is finished process and spinning restart procedure are attached in the driver, and the part aspect is described above.These aspects can be: keep air sphere or specific yarn tension in finish stage and/or spinning stage that connects again of spinning, spinning finish stage and/or spinning connect again the variation of stage fineness of yarn or yarn twist time point (characteristic of yarn can spinning finish stage and/or spinning connect again on a plurality of time points in the different phase (for example reel in pipe top, rewinding around with underwinding etc.) of process change), or be laid on the wire turn steepness of rewinding in the zone.All operations in the tube changng process of describing in detail in DE 100 37 513 A1 patent specifications can be incorporated into the tube changng program.Therefore, the content in this respect of DE100 37 513 A1 is as the integral part of present patent application.
The method according to this invention is preferred for ring spinner.But this method also can be used for funneling spinning machine, cap spinning spindle machine or loop spinning machine.The deposition of yarn is undertaken by the ring rail that the step rail that moves replaces moving.Also can expect the combination motion of ring rail and step rail.By other suitable change, the present invention also is applicable to pot spinning method.But spindle or drafting system roller be single driving or by shared driver drives in any case, realizes by gear drive where necessary.
Description of drawings:
Describe the present invention in detail below in conjunction with accompanying drawing, wherein:
Fig. 1 shows the schematic diagram at the coiling station of ring spinner;
Fig. 2 shows the schematic diagram of the program circuit in the machine controller.
The specific embodiment
As shown in Figure 1, in order to make the drafting system roller coordinated movement of various economic factors of ring ingot ring rail 5, spindle 13 and drafting system 3, corresponding driver for example drawing apparatus driver 4, ring ingot steel neck sheet drive 7 and spindle driver 12 is connected on the machine controller 2.Drafting system 3 comprise the input roller to 15, middle roller to 16 and delivery roller to 17.
If after finishing cop 9, on cop top, subsequently in the process that ring rail 5 moves downward and will manage respectively in the cop bottom at last to reel in the top, rewinding is around being wound on the spindle 13 with underwinding, doffs, takes off one or more cops thereafter in spinning machine successively.Except one and a plurality of yarns were wound on conventional underwinding on the spindle around the underwinding zone, yarn line segment also can be centered around on the spindle circumference and the particularly clamped Guan Ding of clamped device clamps.Very important from this stage that underwinding begins, because if optimum condition do not realize, so from the normal winding run transition before doff inactive state and the process that connects again of spinning subsequently can produce overwhelming majority broken string or for example disturb that yarn 14 comes off from steel traveler 6.The rotational speed N of spindle descends fast in the final stage that cop forms, because the centrifugal force that acts on the yarn reduces, the ballooning of yarn 8 between the steel traveler 6 around drafting system outlet and the cop 9 is along with the disappearance of tension force is tending towards avalanche.This must be by reducing drafting system 3 simultaneously fed distance L and suitably move downward described ring rail 5 and stop.
Fig. 2 show in the machine controller 21 according to program circuit of the present invention.The operator for example has by input module 22 in a plurality of spinning programs that the keyboard of display screen stores from machine controller 21 and chooses the spinning program 23 that needs.Perhaps, the operator manually imports or electronics reads the spinning parameters of spinning program 23, and it is stored in the machine controller 21.
When the beginning spinning process, machine controller 21 is based on the spinning parameters of spinning program of choosing 23 or input and the driver of machines configurations file 24 each drivers of calculating.The a plurality of tube changng programs of storage are important for the present invention in machine controller.According to the spinning program and the machines configurations of operation, choose suitable tube changng program 26 via selection module 25 by machine controller 21.
For at the last of full yarn process or before being about to expire yarn, machine controller 21 starts the tube changng program chosen and described tube changng program is handled, and perhaps moves the working procedure that is used for driver of calculating from the tube changng program.That is to say that in this operation phase, machine controller is no longer according to the spinning program work, but according to the tube changng program work of choosing.Therefore described tube changng program replaces actual spinning program in this stage.
Can be provided with and be suitable for the operator manually chooses tube changng program 26 from a plurality of tube changng programs device.Described machine controller also can be for providing the suggestion of selection to the operator.
If the method according to this invention is applied in funneling spinning machine, cap spinning spindle machine or the loop spinning machine, so mobile ring rail is replaced by mobile step rail (down rail).In addition, in the tube changng program, also to control the funnel motor.Equally, in ring spinner, the motion of step rail can be used as the additional of ring rail motion or replaces.
The advantage of the method according to this invention is that the tube changng program is stored in the machine controller.The operator does not need according to the experience of oneself the tube changng parameter to be imported machine controller.
Instead, the tube changng process is automatically performed by machine controller self and does not relate to the operator.Therefore the method according to this invention guarantees that machine controller carries out the spinning of the optimization program that finishes always, and need not the operator get involved in control.
Because always cut off basically around initial about two meters of middle yarn at subsequently rewinding, this helps standardization ground operation tube changng program for each spinning program, wherein changes the characteristic of yarn targetedly.Therefore the tube changng program is mainly used in and keeps having spun the stable of spinning process in the stage under the situation that operational factor changes, and promptly avoids broken string and other job failure, and prepares to provide yarn line segment with subsequently the spinning process of connecting again for the tube changng operation.
Therefore wherein, for the above reasons, the length of yarn of producing in the tube changng program is inconsistent and can not use with the default value of spinning program, and this is unimportant.It is short as far as possible that but described length of yarn should keep.
In principle, the process that connects again of the spinning of carrying out before the spinning program actually also can be reeled in a similar fashion by machine controller.The a plurality of spinning of storage connect program again in computer for this reason.Machine controller connects program again based on automatically choosing best spinning by the configuration of given spinning program of operator and machine by option program.As an alternative, also can manually choose spinning this operator and connect program again, choose spinning by the corresponding suggestion of machine controller where necessary and connect program again.
Should be understood that the tube changng program also can be stored in the controller that is subjected to machine controller control, and call and be transported to machine controller so that carry out by described controller.
