Description
Technical field
The present invention relate to a kind of lappet type jacquard warp lappet start control program design implementation method, especially prevent by
Large area broken yarn when the weaving that broken yarn defect leads to initiates is existed on lappet type jacquard warp principle, and design with real
During existing RJWB series tricot machine Jacquard control program, particularly wherein lappet is started the design and implementation methods of control program.
Background technology
Because lappet type jacquard warp production of machinery principle is advanced, technical difficulty is high, and this kind of machine is in global model at present
In enclosing, only one business monopoly of German Karl Mayer Textilmaschinenfabrik GmbH produces and supply.This kind of machine mainly has
The types such as RJWB3/2F, RJWB4/2F, RJWBS5/1F, RJWB6/2F and RJWB8/2F.Due to the weaving of lappet type jacquard warp
The added value of product going out is higher, the therefore domestic research and development also just having started such machine in recent years, in R＆D process, due to
RJWB Series machine has EFS single thread selecting device, has scissors apparatus for the yarn floating during cutting off braiding simultaneously
The structural yarn with ground, during braiding, EFS device and lappet yarn sley point JB1.1 cooperate, and cloth cover needs lappet
When, in EFS device, crochet hook does not stretch out, and JB1.1 sley point drives lappet yarn to be woven, thus forming lappet simultaneously；When not
When needing lappet, in EFS device, corresponding crochet hook stretches out the yarn catching on JB1.1 sley point, and is clamped on EFS device,
After several rows, the yarn of clamped yarn to cloth cover is cut off by shears thus forming independent lappet, when cloth cover again
Secondary JB1.1 sley point drives lappet yarn to be woven when needing lappet, and when weaving several row, cloth cover arrives the clamping of EFS crochet hook
Yarn between point is cut off by shears, and the yarn the end of a thread cut off when crochet hook stretches out again is simultaneously taken away thus completing by air intake device
One cycle of operation.The cooperation of JB1.1 and EFS is extremely important in this process, and during this, lappet yarn only can be located
In two states：(1) lappet yarn does not weave and is stretched out and clamped by the crochet hook of EFS device；(2) lappet yarn enters
Braiding, EFS crochet hook keeps clamp position motionless；If lappet yarn does not weave simultaneously and not by EFS in weaving process
Device clamps, then in lappet yarn because one end is on cloth cover, lappet yarn is hanging simultaneously, with the carrying out of braiding, vacantly
Yarn enter shears working area, then lappet yarn is cut off, and is not clamped by EFS, then yarn is under tension
Shake off sley point, form broken yarn.If this kind of situation occur woven initial when, large area lappet yarn can be led to break
Yarn.In RJWB Jacquard control system, because the crochet hook of EFS only has 2 states：Crochet hook stretches out, and crochet hook does not stretch out.
In flower pattern, the action message of EFS crochet hook is that patterning design CAD software organizes no lappet according to lappet in flower pattern
The action message automatically generating during tissue switching, then for the first row in technique, if the first row exists in flower pattern
Do not need the region of lappet, then the corresponding EFS crochet hook in non-lappet region will keep not stretching out state.It is loaded into merchant when new flower-shaped
When in card controller, machine starts woven first row crochet hook and is failure to actuate, simultaneously because initial row is non-lappet tissue,
So lappet yarn also will not be woven, and now due to being braiding initial state, lappet yarn is not clamped by EFS crochet hook
Living, then occurred as soon as yarn and be not braided and be not clamped, as soon as thus leading to machine startup, being cut off by shears, occurring
Large area lappet yarn broken yarn, thus lead to production cannot continue.
In the present invention, involved lappet is started and is defined as follows：
Lappet is started definition：In lappet type jacquard warp, due to the particular/special requirement of machine, special one kind of design
Flower pattern technique, in process, initial row is designed to lappet tissue, and before producing common process, braiding one rises this technique
Headdress flower type circulates and only weaves once, thinks that common process does initial preparation, and playing prevents initial broken yarn and flower pattern prepares
Effect.
The method of traditional this problem of solution is：During design flower pattern technique, the initial row of technique is designed to lappet group
Knit, we commonly referred to as start lappet, after the several row of lappet of starting, are only normal design technique.
This solution there is problems that：Flower pattern technique due to process desinger's design is limited to spend high number
According to, and actual weaving process is then successive and circulates execution process data, then lead to the cloth cover weaving out to occur
Start the circulation of lappet, and this part lappet of starting is not then the product that client needs, and affects very much the quality of product, simultaneously
Waste a large amount of yarns.
Therefore, in the production of RJWB fabric, there is a problem of starting, then lead to production cannot continue without lappet of starting
Continuous, or have a strong impact on the attractive in appearance of flower pattern technique, if adding, in flower pattern technique, lappet of starting, appearance in cloth cover can be led to
Lappet of starting circulates, and affects product quality, and wastes yarn.
Content of the invention
Lappet type jacquard warp lappet proposed by the present invention start control program design implementation method technical scheme be：
Before the production flower pattern technique that takes up one's knitting, first lappet flower pattern technique of starting is directly stored in lappet type Jacquard
In the nonvolatile memory within Jacquard control device of tricot machine, in this memorizer, memory space is divided into three
Point：(1) produce and use flower pattern technique memory block；(2) lappet is started flower pattern technique memory block；(3) other data storage areas；Deposit for three
There is not overlapping region in storage area domain, production flower pattern technique stores (1) area each other, and lappet flower pattern technique of starting stores
(2) area, Jacquard control system other data required arrive (3) area in storage, so, first weave before producing flower pattern craft woven
(2) lappet in area is started flower pattern technique, when lappet is started after flower pattern craft woven finishes, then the production flower weaving (1) area
Type technique, afterwards, without reloading new flower pattern technique, then machine will circulate braiding production flower pattern technique.From
And realize starting only to weave once preventing broken yarn, recirculation weaves lappet of starting afterwards, only circulation braiding production flower pattern work
Skill.
Lappet flower pattern technique of starting and production flower pattern technique, design is the same with producing process data process, simply upper
It is loaded into the internal different memory space of Jacquard control system in machine program.
Preferably, start lappet flower pattern technological design and requirement：
(1) initiateing several rows must be lappet tissue.
(2) lappet flower pattern technique course count of starting must be the multiple of 8 rows.
(3) after the lappet of several rows is organized, it is right that crochet hook hooks up successively lappet flower pattern of starting according still further to specified order
The yarn answered, this process can also check every crochet hook whether can normal work, treat that all of lappet yarn is all hooked pinhock and goes out
And when keeping, start normal flower pattern craft woven, according to flower pattern information, some lappet yarn is reentered braiding,
And another part yarn continues to be hooked pinhock to go bail for and holds not woven condition.
Preferably, lappet is started control program workflow：
(1) designer's design one is started lappet technique and a normal production flower pattern technique.
(2) load this lappet of starting to Jacquard control system in host computer, this lappet data storage of starting in Jacquard
Lappet memory area of starting in flower pattern memorizer in control system.
(3) load normal flower pattern technique in host computer Jacquard control system, this flower pattern technique is stored in flower pattern and deposits
Production in reservoir flower pattern technique memory area.
(4) when loading production labor skill flower pattern, host computer sends one and arranges mark order of the bit of starting, Jacquard control system
Internal receipt just puts head flag bit together to after this order, and when machine startup weaves, Jacquard starts lappet control program then
First judge whether flag bit of starting is true, if very then first carrying out lappet technique of starting, after the lappet that completes to start, reset
Head flag bit, enters back into the braiding circulation of production labor skill flower pattern, thus lappet of starting in whole weaving process only occurs one
Secondary.
(5) when the production more renewing flower pattern technique, then Jacquard control system only needs execution step 4, that is, rises
Headdress flower type only needs to load once, and the production flower pattern technique that more renews afterwards is without reloading flower pattern of starting.
(6) only when needing to have changed head technique, just need to reload to start, that is, execution step (3)～
(4).
The invention has the beneficial effects as follows, solve the problems, such as broken yarn and lappet circulation of starting, and decrease yarn to waste, subtract
Lack the shutdown that broken yarn leads to and the ineffective time such as entry, substantially increase product quality and production efficiency.

Specific embodiment
Below in conjunction with preferred specific embodiment, such scheme is described further.Embodiment is with RJWB3/2F lappet type
Illustrate as a example jacquard warp, because RJWB3/2F is representative type in lappet type jacquard warp series, contain
All core components of lappet jacquard warp, it is therefore to be understood that these embodiments are to be not limited to for the present invention is described limit
The scope of the present invention processed.The implementation condition adopting in embodiment can be done according to the condition of concrete producer and adjust further, do not note
Bright implementation condition is usually the condition in normal experiment.
Embodiment lappet type jacquard warp lappet start control program design implementation method
In FIG, lappet type jacquard warp RJWB3/2F sley bar configuration structure in figure, (1) is JB1.1, and (2) are pressure yarns
Plate, (3) be comb GB2, (4) be two and half machines number configuration jacquard comb JB3.1 and JB3.2 composition JB3, (5) are sinkers,
(6) groove pin nook closing member, (7) are knitting needles, and (8) are knocking over comb tablets, (9) shears sley bar, and (10) single thread selects sley bar.In figure is band shears
The representative type of one of lappet type jacquard warp series, control program of on this machine, braiding being started
If machine method, it is also applied for other lappet type jacquard warps with shears, the present invention is with this type as embodiment.Wherein (9)
Constitute single thread selecting device (EFS) with (10) and air suction mechanism, its workflow is as shown in Figure 2.
In fig. 2, in lappet type jacquard warp, the working condition of single thread selecting device EFS only has two kinds：One kind is hook
Pin stretches out, and enters woven extent, is not needed the lappet yarn weaving to hook from JB1.1 and hook separates out woven extent, works as hook
Pin exits woven extent, and the lappet yarn on JB1.1 stops braiding, and the yarn that other are not hooked then continues to weave, 3～4
After row, lappet yarn is cut off at weaving point along exiting by thread cutting mechanism；Second state is：Crochet hook keeps not stretching out shape
State, and require the lappet yarn on now JB1.1 must be hooked by yarn, without being hooked, then corresponding
Lappet yarn on JB1.1 must participate in lappet braiding.When lappet yarn enters woven extent and participates in weaving 3～4
After row, the unnecessary lappet yarn between crochet hook bite and entrance weaving point is cut off by thread cutting mechanism.Finally, in EFS work
The Yarn break producing during work by air suction mechanism, walk in time by cleaning.
In figure 3, in order to illustrate how lappet type jacquard warp EFS works, and how to produce when braiding is initial
Broken yarn, has been divided into 11 typical steps EFS work process：A () crochet hook rises；B () hooks yarn；C () crochet hook resets；
D () cuts off the end of a thread；E () clamps the end of a thread；Put after (f) sley bar；(g) overlap；H () enters braiding；I () cuts off the end of a thread；J () presss from both sides
Hold the end of a thread；K () siphons away yarn.In figure, A point is knitting needle woven extent, and B point is EFS device crochet hook bite, and O point is lappet yarn
Line sley point.In (a), when just proceeding by braiding, EFS crochet hook is not also chosen by Jacquard control system, and crochet hook is in just
Beginning extreme lower position, and keep not stretching out state.B, in (), when in EFS, a certain piece of crochet hook is selected, crochet hook is with the motion of main shaft
Rise and stretch out, hook lappet yarn when being elongated between JB1.1 and knitting needle.In (c), after crochet hook hooks lappet yarn,
Decline with main shaft and retracted for clearance arrives and do not stretch out state, and lappet yarn now is clamped in B point by crochet hook, wait is next time
Choose and stretch out.This piece of Jacquard sley point that the lappet yarn being hooked is located, will not carried out under the control of Jacquard control system
Overlap moves, so that this lappet Jacquard yarn cannot be woven in the middle of fabric, that is, lappet yarn exits woven extent.
Ground stitch yarn continues to be woven, after ground weave 3～4 row, the carrying out batched with tractive, and knitting zone
Lappet yarn line segment between domain A point and crochet hook bite B drops to the shears working area of thread cutting mechanism, then very close to braiding
Cut off at the C point in region, such as shown in figure (d).As shown in figure (e), after yarn is cut off, lappet yarn one end becomes freely
End, other end is clamped by crochet hook, thus lappet yarn will not skid off after being cut off from guide eyelit causes broken yarn.Figure
In (f), when temporarily exiting this root lappet yarn of braiding under the requirement of flower pattern control information, need to reenter woven extent
When continuing to participate in braiding, front jacquard comb JB1.1 will Jacquard control device control under to machine after swing, be that overlap does standard
Standby.In figure (g), reliable and accurate for ensureing overlap, front Jacquard JB1.1 slightly pushes in the process, completes pin foremast
Yarn.In figure (h), now single thread selecting device and Jacquard control system coordinate, and control EFS not needle selection, lappet yarn will again by
Braiding is entered, and crochet hook continues to clamp the unnecessary lappet yarn that section fails to be woven in fabric.In figure (i), enter knitting zone
Lappet yarn normally weave lappet, braiding 3～4 rows after, the carrying out, woven extent A point and the hook that batch with tractive
Between pin bite B, unnecessary yarn drops to and is cut off by thread cutting mechanism at the C point of shears working region.In figure (j), after cutting off
Lappet yarn line segment B point is clamped in by crochet hook.In figure (k), when needle selection next time, crochet hook stretches out again, and no longer clamping is many
Remaining lappet yarn, then unnecessary lappet line segment siphoned away by air suction mechanism.The refuse yarn producing so in compilation process obtains timely
Cleaning is it is ensured that machine normal work.
In the diagram, in figure region A is no lappet region, and this region lappet yarn is not involved in weaving, and in figure region B is floating
Stricture of vagina region, this region lappet yarn participates in being knitted to form lappet.
In above work process, if crochet hook stroke defect, or crochet hook in flower pattern, is required to hook lappet yarn, and real
Border machine is not hooked to when running, then all can cause broken yarn.And in lappet type raschel machine, start in actual production
When, if there is no lappet region in technique flower pattern first row, then now according to flower pattern information, now EFS crochet hook keeps
Do not stretch out state, according to above work process, now lappet yarn should be hooked pinhock and lives and be clamped in EFS
On, but, due to being now first row of flower pattern, it is not hooked to lappet yarn before the crochet hook of EFS, then machine one opens
Dynamic, then yarn is unbraided and is not clamped, and just skids off from guide pin hole, causes broken yarn phenomenon, and this problem is gone into business in lappet type
Cannot avoid on card tricot machine, therefore, the present invention proposes one kind and starts control program solving this problem.
In Figure 5, start lappet technique it is preferred that first having to design one in control program of starting proposed by the present invention,
When this process stipulation initiates braiding, all of lappet yarn all enters braiding and (correspond to all of crochet hook all to keep not stretching out shape
State), after waiting all lappet yarns to weave several rows, crochet hook hooks up corresponding yarn successively according still further to order, and this process is also
Can check every crochet hook whether can normal work, when all of lappet yarn is all hooked pinhock and goes out and keep, start normal
Flower pattern craft woven, according to flower pattern information, some lappet yarn is reentered braiding, and another part yarn continue
It is hooked pinhock and goes bail for and hold not woven condition.
For realizing object above, design following lappet technique of starting：Initiate several rows, all of knitting needle all weaves
Lappet is organized, and subsequently, on machine fabric width, lappet yarn exits braiding as requested successively.For convenience, from a left side to
Right by lappet yarn number consecutively, that is, the 1st, 2,3,4 ... n-1, n root.Way proposed by the present invention is：Certain row, allows the 1st, 1
+ m, 1+2m, 1+3m ... ... root lappet yarn is first deactivated, and after weaving several rows, then allows the 2nd, 2+m, 2+2m, 2+
3m ... ... root lappet yarn exits braiding, after weaving several rows, then allows the 3rd, 3+m, 3+2m, 3+3m ... ... root lappet yarn
Line exits braiding, so circulates, until all of lappet yarn all exits braiding, enters back into the braiding of normal flower pattern technique.
Lappet technique of starting according to design philosophy proposed by the present invention design is it is preferred that its Jacquard plan of weave such as Fig. 5 institute
Show, in figure Lycoperdon polymorphum Vitt represents braiding lappet tissue, and white portion is then earth mat.
In figure 6, this figure is that in Fig. 5, Jacquard plan of weave is converted to the pattern figure after lappet Jacquard WB pattern figure.In figure
Black portions represent that crochet hook stretches out work, and lappet exits braiding, and grey parts are braiding lappet tissues, and white portion represents braiding
Earth mat.This example is used for patterning design thought of starting is described, lappet technique of starting is not limited to this example, as long as flower pattern technique initiates
Several rows all weave lappet tissue, are used for doing follow-up flower pattern preparation and anti-broken yarn function before normal production flower pattern technique
Lappet technique be scope of the invention.
In the figure 7, braiding solution thought of starting proposed by the present invention, such as shown in figure (a), design one is started lappet flower
Type, was loaded in Jacquard control system before production flower pattern technique A, and it is entirely lappet tissue that lappet of starting initiates row,
When then weaving initial, all lappet yarns will be woven in cloth cover, will not cause initial broken yarn, after lappet yarn exits braiding,
Crochet hook action is hooked to and clamps lappet yarn, and take up one's knitting technique A afterwards, thus solving the problems, such as initial broken yarn.
In Traditional solutions, starting lappet and production flower pattern technique A accomplishes, in a flower pattern, to be loaded into merchant together
In card control system, then when braiding starts, lappet can be caused to start flower pattern circulation braiding, such as shown in figure (b), so cause
Yarn wastes, and cloth cover effect is undesirable.The present invention proposes to start lappet flower pattern and production flower pattern technique separately designs, and respectively
Load, when machine takes up one's knitting, to be dispatched two flower pattern by Jacquard control program, lappet flower pattern of starting only weaves once, afterwards,
Only circulation braiding production flower pattern A, such as shown in figure (c), in this manner it is possible to solve initial broken yarn to have no effect on normal production.
In addition, when switching produces flower pattern technique, also can produce initial broken yarn, in this regard, control of starting proposed by the present invention
, using automatic loading method of starting, after loading when starting, if switching production technology flower pattern, control program is automatic for program
Loading is started lappet, so produces the lappet band of starting of transition in technique switching, thus when solving switching and producing flower pattern technique
The broken yarn leading to, as shown in figure (d), after lappet of starting loads, loads flower pattern A, after the production of flower pattern A completes, needs more
Change flower pattern B to be processed producing, then only need to load flower pattern B, and without loading lappet of starting again, because starting control journey
Sequence automatically loads and starts.
In fig. 8, it is preferred that control program of starting comprises two parts in the present invention, a part is in the integrated control of tricot machine
In system, a part is in Jacquard control system.
Lappet type Jacquard control system hardware mainly includes：Jacquard control device (1), tricot machine integrated control system (2),
Jacquard driving means (3), main shaft proximity switch (4), spindle motor (5) and mechanical body (6).And control object is main on machine
There is front lappet Jacquard sley bar JB1.1 (601), EFS single thread selects system (602).
The invention mainly relates to control program of starting in Jacquard control device (1), flower in tricot machine integrated control system (2)
Type loading procedure, therefore here mainly illustrate control program design and implementation methods of starting.In Jacquard control device (1), rise
Head control program primary recipient is derived from proximity switch (4) signal of tricot machine main shaft, controls in tricot machine integrated control system (2)
Program is mainly responsible for transmitting control data and the pattern data loading.Jacquard control device (1) is according to pattern data with close to opening
OFF signal is executing flower pattern information, and sends control signal to Jacquard driving means (3), and then Jacquard driving means (3) can root
Drive JB1.1 (601) and EFS (602) according to machine shaft operating condition so as to carry out cooperation normal work.In Jacquard control
Device (1) is internal, has a nonvolatile memory (11) to be used for storing pattern data, the present invention is divided into 3 this memorizer
Related independent memory block：Production flower pattern technique memorizer (111), start lappet flower pattern technique memorizer (112) and other
Data storage area (113).
Load lappet of starting, flower pattern technique, other controls to Jacquard control device (1) by human-computer interaction interface (201)
Information, after Jacquard control device (1) receives data, starts lappet data Cun Chudao of starting lappet flower pattern technique memory block
(112), flower pattern process data stores production flower pattern technique memory block (111), and the control information such as flag bit of starting stores
Other data storage areas (113).When start machine weaves, Jacquard control device (1) receives proximity switch on main shaft (4)
Trigger, takes up one's knitting, and first weaves lappet of starting, and after braiding of starting completes, starts the cycle over braiding flower pattern process data.
In fig .9, the host computer procedure of the present invention is mainly responsible for lappet technique of starting in tricot machine integrated control system
Loading with flower pattern technique and the information such as transmitting control commands.Host computer start loading flow process mainly include：Design lappet of starting
Flower pattern, selects to be loaded flower pattern of starting in host computer, and the flower pattern of starting of loading selected, to Jacquard control device, judges whether
Load successfully, if success, point out to load success and continue, otherwise prompting loads unsuccessfully to return and reselects flower pattern of starting；Rise
Head loads production technology flower pattern after loading success, judges whether to load successfully, if success, sends to Jacquard control device
Leader will setting command, if failure, points out unsuccessfully to return loading production technology flower pattern；Point out after loading process flower pattern success
Load successfully, and make machine enter ready state, afterwards, machine starts to produce, after completing to produce, how to need to change
Production technology is then directly entered loading production craft step, if without completing production process.
Need explanation, it is that explanation is started the thought of Loading Control program and side that this host computer loads flow chart of starting
Method, when implementing, this partial function is a part for integrated control system.
In Fig. 10, host computer loads to Jacquard control device when starting lappet and production technology in addition it is also necessary to Jacquard controls
Lappet Jacquard control program of starting in device carries out coordinating and just can complete.Lappet Jacquard of starting in Jacquard control device controls
Program flow diagram, as illustrated, mainly one circulation, judges which kind of data is the data from host computer be in the circulating cycle, if
It is flower pattern technique of starting, then flower pattern technique of starting is stored lappet in nonvolatile memory and start memory block, if raw
Produce flower pattern technique, then store production pattern data memory block in nonvolatile memory producing flower pattern process data；?
After judge whether it is that setting is started mark order of the bit, if it is in Jacquard control device, setting flag bit of starting is true.From
And the loading cooperation of lappet and flower pattern technique of realizing starting with host computer, and flag bit of starting is set in Jacquard control device.
In fig. 11, it is properly and is loaded in Jacquard control device when lappet is started and produces flower pattern technique, and machine
After device is ready, in Jacquard control device, Jacquard control program of starting then responds the close of main shaft by interrupt service routine
Switching signal, and responded according to pattern data.Main flow is：When a proximity switch signal arrives, triggering is interrupted,
Control program enters interrupt service routine,
Whether the flag bit that first determines whether to start is true, if true, then first carry out lappet and start pattern data, then interrupts
Judge data or needle back data before pin again, afterwards, carry out signal filtering anti-interference it is determined that after needle back before pin again from
The data of corresponding row is taken out in head lappet memory block, and drives jacquard needle block and the correct action of EFS device, completes a lappet
The braiding of row, the signal how to arrive is needle back signal, then judge lappet pattern data after needle back signal is finished
Whether woven finish, no end then continuing, if finished, flag bit is set to false as starting, exiting lappet of starting and compiling
Knit.
Follow-up proximity switch signal, through judging it is the trigger producing flower pattern technique, then judges needle back signal before pin,
Equally it is filtered anti-interference it is determined that taking out corresponding row after needle back signal before pin from production flower pattern technique memory block
Pattern data, and drive jacquard needle block and EFS device action, complete the braiding of a production flower pattern row, how to arrive is
Needle back signal, then judge after needle back signal is finished whether production flower pattern weaves and finish, such as not complete, continues, if complete
