Abstract
A sliding resistance adding device for a weft knitting machine capable of adding a sliding resistance applying less load to the movement of a carriage and capable of being rapidly and securely stopped when entrainment is stopped. A permanent magnet (23) adds a first sliding resistance between a holding arm (21) and a guide rail (25). An electromagnet (26) magnetically adding a second sliding resistance in the clearance thereof from the holding arm (21) is fitted to the carriage (13). When the carriage (13) stops moving, though the holding arm (21) attempts to continuously move by inertia, a sliding resistance formed of the sum of the first sliding resistance and the second sliding resistance acts on the holding arm (21) to rapidly stop it. When the carriage (13) entrains the holding arm (21), a load thereon can be reduced since the second sliding resistance does not act thereon. When the carriage (13) starts the entrainment of the holding arm (21), a difference between the first sliding resistance and the second sliding resistance forms a sliding resistance to reduce the sliding resistance acting thereon in starting the entrainment so as to reduce the occurrence of impact and noise.
Description
Technical field
The present invention relates to a kind of in straight-bar machines, the sliding resistance adding device for weft knitting machine of additional resistance to sliding on the moving-member that slides along the length direction of needle-bar with the cam carrier interlock.
Background technology
In the past, in straight-bar machines, be provided with a plurality of knitting needles on the needle-bar side by side, supplied with stocking yarn when sequentially carrying out braid movement to carry out the braiding of knitted fabric with knitting needle.The braid movement of knitting needle order is realized with cam mechanism by the braiding that is loaded on the cam carrier that moves along needle-bar, with the thread-carrier of cam carrier interlock stocking yarn is supplied with to knitting needle.
Figure 15 briefly shows the structure of the mechanism of cam carrier and thread-carrier interlock.In the v type needle bed straight-bar machines of tooth mouth face-off, above the tooth mouth, setting up guide rail 1 at a pair of needle-bar in front and back as guide rail.Bridge shape bar 2 between the cam carrier before and after being connected on the needle-bar haunts linkage pin 3 in the part of crossing over guide rail 1, can make thread-carrier 4 interlocks as moving-member that can advance along guide rail 1 selectively.Be provided with the interlock recess 5 that can fasten with the linkage pin 3 of outstanding state in thread-carrier 4 sides.
The yarn feeding set positions of supplying with stocking yarn to knitting needle in the knitting knitting fabric process is as upper/lower positions: by being equipped on the knitting cam on the cam carrier, after knitting needle enters the tooth mouth, retreat midway from the tooth mouth.Move and in other direction moves during shared knitting cam in the direction to cam carrier, the yarn feeding position need be according to the moving direction of cam carrier, is that benchmark switches on the different positions with the position of knitting cam.For with the moving direction of cam carrier accordingly, to only with the knitting cam yarn feeding on the position of certain distance of staggering, interlock recess 5 will be provided with the width of regulation.The counter-rotating of the moving direction by cam carrier, linkage pin 3 switches to the opposing party to the butt position of interlock recess from the right-hand member 5a of interlock recess 5 and the side the left end 5b.
Cam carrier side from move along knitted fabric when linkage pin 3 is sunk, stops the interlock of cam carrier and thread-carrier 4, as cam carrier be in mobile in, then thread-carrier 4 also can continue to move along guide rail 1 under inertia., wish that thread-carrier 4 rests on the position that stops interlock.Linkage pin 3 is in case move up to thread-carrier 4 and stop from removing the position that fastens with interlock recess 5, then then makes linkage pin 3 outstanding and when making thread-carrier 4 interlocks, the position can be failed to understand.
Stop to stop in order to make with the relative immediately guide rail 1 of thread-carrier 4 of cam carrier interlock, be on thread-carrier 4, and guide rail 1 between additional resistance to sliding.The additional of resistance to sliding also mechanically realized.But the also resistance to sliding of additional magnetic (for example with reference to No. 2858768 communique of Japan Patent).
Resistance to sliding between thread-carrier 4 and the guide rail 1, owing to when cam carrier and thread-carrier 4 interlocks, the moving load of cam carrier is strengthened, therefore preferably less., after interlock stopped, it was elongated to stop required distance up to thread-carrier 4, and the possibility of bad phenomenon such as surpassed distance can take place.When the applicant utilizes magnetic force in straight-bar machines, proposed the magnetic circuit that a kind of use contains permanent magnet and electromagnet,, come the technology (for example with reference to Japanese kokai publication hei 3-280405 communique) of switch in magnetic force intensity by pulse type energising to electromagnet.
As No. 2858768 communique of patent, only additional resistance to sliding between thread-carrier and guide rail can increase the load of thread-carrier to the cam carrier in the interlock.When mechanically paying resistance to sliding, also abrasion easily.In addition, when cam carrier counter-rotating,, can change with the position of linkage pin butt at the interlock recess that fastens with linkage pin.
For example in Figure 15, suppose that cam carrier moves right, finish the braiding of a row amount, in ensuing row braiding, cam carrier is moved to the left.When cam carrier moves right, the right-hand member 5a butt of linkage pin 3 and interlock recess 5.Even cam carrier stops, thread-carrier 4 also can further move right under inertia.Resistance to sliding hour, thread-carrier 4 continues to move right.Under the state that linkage pin 3 is given prominence to, the left end 5b of interlock recess 5 and linkage pin 3 butts are to stop to move of thread-carrier 4.When linkage pin 3 was given prominence to, thread-carrier 4 can further move to the right, and the possibility of surpassed distance can take place.When producing surpassed distance, even make linkage pin 3 outstanding, cam carrier is moved to the left, interlock recess 5 also can leave linkage pin 3, can not make thread-carrier 4 interlocks.
Resistance to sliding as thread-carrier 4 relative guide rails 1 is bigger, when then the moving direction of cam carrier reverses at least, but makes by linkage pin 3 in the scope of thread-carrier 4 interlocks, and thread-carrier 4 is stopped., the interlock of thread-carrier 4 is owing to be to realize by the linkage pin 3 and the left end 5b butt of interlock recess 5, thereby can impact when linkage pin 3 and left end 5a butt.The resistance to sliding of thread-carrier 4 relative guide rails 1 is big more, and this impact is then big more.This impacts and can produce noise, and the repeated stock meeting damages.In addition, in order to improve productivity, when strengthening the translational speed of cam carrier, impact and noise can become big.
Disclosed as Japanese kokai publication hei 3-280405 communique, as using electromagnet, then can be controlled the resistance to sliding that utilizes magnetic force to add., on aforesaid thread-carrier 4, be difficult to be mounted with the structure that contains electromagnet.Wish miniaturization as far as possible and lightweight along the thread-carrier 4 that guide rail 1 is advanced.Loading the structure that contains electromagnet on thread-carrier 4 can gain in weight and cause to maximize.In addition, also need to supply with the electric power that makes the electromagnet excitation.

Fig. 4 illustrates near the side sectional structure the tooth mouth 15 of straight-bar machines 11 of Fig. 1.The cam carrier 13 of advancing along the length direction of front and back needle-bar 12 can be respectively and keeping arm 21 interlocks, and have interlock state switching mechanism 22, permanent magnet 23, connecting portion 24, guide rail 25, electromagnet 26, metal tape 27, steel band 28, linkage part 29 and linkage pin 31 respectively.The front end of knitting needle 14 not only enters tooth mouth 15 from each needle-bar 12, and the parts that sinker 42 grades are used for knitting knitting fabric also enter from each needle-bar 12.Yarn feeder 16 not shown upper end side relatively keeping arm 21 dress take off.The yarn feeder 16 that is installed on the keeping arm 21 has feed 16a in the lower end, stocking yarn can be supplied with to the knitting needle 14 that enters tooth mouth 15.
Fig. 5 briefly shows the relation of control and electromagnetic braking due to electromagnet 26 energising of the mobile status of cam carrier 13.Cam carrier 13 can replace switching owing to back and forth advance along the length direction of needle-bar 12 on 2 directions of advance of right lateral and left lateral.The control of the mobile status by cam carrier 13, the at the uniform velocity zone of on each direction of advance, be provided with acceleration region, advancing with certain speed and speed is reduced up to the deceleration zone that stops from the inactive state hoisting velocity.The woven extent of carrying out knitting knitting fabric is main with at the uniform velocity regional corresponding.Woven extent also can be set for and exceed acceleration region or the zone of slowing down.Electromagnetic braking due to the electromagnet 26 affacts the last of the zone of slowing down to the right shown in the oblique line that has a down dip.This is after stopping because of cam carrier 13, can stop keeping arm 21 reliably.In addition, acceleration region generation effect at first.This be because, before the end butt of linkage pin 31 and interlock recess 30 during effect the 2nd resistance to sliding.
Fig. 6 illustrates cam carrier 13 and moves to side view under the state that makes remaining device 19 places that yarn feeder 16 stops.Be simplified illustration, though the more structure of putting down in writing a policy bed 12 sides, the median plane 15a of relative tooth mouth 15, the opposing party's needle-bar 12 sides also have identical structure.On each keeping arm 21, can keep maximum 3 yarn feeders 16.But the feed 16a of yarn feeder 16 lower ends is owing to from facing roughly same position supply stocking yarn of tooth mouth 15, can not be installed to a plurality of yarn feeders 16 on the keeping arm 21 simultaneously.Make remaining device 19 that yarn feeder 16 stops as shown in Figure 1, because staggered positions configuration on the length direction of needle-bar 12, thereby a plurality of yarn feeders 16 are stopped in the hands-off each other mode of feed 16a.
As above-mentioned, in the present embodiment, in straight-bar machines 11, for with cam carrier 13 linkedly, to the keeping arm 21 additional resistances to sliding as moving-member of sliding along the length direction of needle-bar 12, sliding resistance adding device for weft knitting machine comprises guide rail 25, as the interlock state switching mechanism 22 that connects switching device shifter, as the permanent magnet 23 of the 1st resistance to sliding attachment device, as the electromagnet 26 of the 2nd resistance to sliding attachment device.Guide rail 25 sets up along the length direction of needle-bar 12 is parallel, keeping arm 21 is slided move.Interlock state switching mechanism 22 changeable for be connected between keeping arm 21 and the cam carrier 13 and the state of cam carrier 13 and keeping arm 21 interlocks or cam carrier 13 not with the state of keeping arm 21 interlocks in any one.Permanent magnet 23 adds the 1st resistance to sliding between guide rail 25 and keeping arm 21.Electromagnet 26 is additional the 2nd resistance to sliding between keeping arm 21 and cam carrier 13, when the counter-rotating of cam carrier 13 moving directions, makes the 2nd resistance to sliding littler than the 1st resistance to sliding at least.In a single day cam carrier 13 stops to move, and keeping arm 21 will continue to move under effect of inertia.Because on keeping arm 21, and the guide rail 25 that stops between additional the 1st resistance to sliding, and the cam carrier 13 that stopped moving between additional the 2nd resistance to sliding, thereby the part that stops relatively, effect has the resistance to sliding of the 1st resistance to sliding and the 2nd resistance to sliding sum, can promptly stop.
When cam carrier 13 and keeping arm 21 interlocks owing to do not act on the 2nd resistance to sliding, thereby in 2 resistances to sliding, relatively cam carrier 13 what be moved into load only is the 1st resistance to sliding, can make load less.When cam carrier 13 beginnings and keeping arm 21 interlocks, act on the 1st resistance to sliding between keeping arm 21 and the guide rail 25, and the 2nd resistance to sliding that has begun to have between the cam carrier 13 that moves and the keeping arm 21 is an opposite direction, become poor by the 1st resistance to sliding and the 2nd resistance to sliding in fact, the state that keeping arm 21 is prevented on guide rail 21, resistance to sliding when acting on interlock and beginning is less, can reduce and impact or the generation of noise.
In addition, as the keeping arm 21 of moving-member owing to have a plurality of retainers 18, described retainer remains in the position of feed 16a facing to the knitting needle 14 of braid movement with the yarn feeder 16 that front end has the feed 16a that is used for the confession yarn, compare with the state that yarn feeder is independent, quality is bigger, and it is big that the inertia when stopping also to become.Yet the resistance to sliding that acts on the interlock end owing to keeping arm 21 when stopping is bigger, thereby can stop reliably.Because when the direction transformation of cam carrier 13, the substantial resistance to sliding of guide rail 25 can be less relatively, thereby can reduce the generation of impact or noise.
That is, controllable the 2nd resistance to sliding is greater than the 1st resistance to sliding, and can little by little change.For example, when keeping arm 21 as moving-member is stopped, can making the 2nd resistance to sliding, can instantaneously stop greater than the 1st resistance to sliding.In addition, the 2nd resistance to sliding when cam carrier 13 back and forth reverses can little by little become big in the deceleration zone, can little by little diminish at acceleration region, can be with the impact during butt is relaxed with beginning to fasten with the interlock recess 30 at fastening position as the interlock of linkage part 29 as the linkage pin 31 of control assembly.
In the zone of slowing down, when cam carrier 13 stops, also can make the 2nd resistance to sliding become big control gradually, make keeping arm 21 surpassed distances as moving-member, make position with interlock recess 30 ends of linkage pin 31 butts, stop a side of 31 butts of linkage pin before from cam carrier 13, switch to the end of a relative side.Then, when cam carrier 13 makes moving direction counter-rotating and begins to move, can be 0 from speed, linkage pin 31 begins the operation of keeping arm 21 with the state of the end butt of interlock recess 30, thereby can avoid beginning butt and the impact that produces from the state of having distance between linkage pin 31 and the end in vain.Have in vain up to the end of the interlock recess 30 of 31 butts of linkage pin apart from the time, as reduce the control of the 2nd resistance to sliding, with the acceleration region initial stage that begins to move at cam carrier 13, make the operation of the 2nd resistance to sliding greater than the 1st resistance to sliding ground beginning keeping arm 21, and before woven extent, the end of interlock recess 30 gradually with linkage pin 31 butts, then can not produce impact.
In addition, as the 2nd resistance to sliding attachment device, also can have the 2nd permanent magnet that produces magnetic attraction and add the 2nd little resistance to sliding than the 1st resistance to sliding.Owing to, can stably add the 1st resistance to sliding and the 2nd resistance to sliding all the time with the additional resistance to sliding of the 1st and the 2nd permanent magnet.Because the 2nd resistance to sliding is less than the 1st resistance to sliding, when cam carrier 13 moving directions reversed, till the interlock of keeping arm 21 began, keeping arm 21 guide rail 25 relatively was static, only made cam carrier 13 side shiftings.
Fig. 7 briefly shows the structure relevant with the interlock state switching mechanism 22 of Fig. 1 and connecting portion 24.On interlock state switching mechanism 22, be provided with the linkage pin 31 as projecting part of the overhang that can change relative cam carrier 13 sides.Linkage pin 31 is accommodated in the pin reception hole 33, by spring 34, along from pin reception hole 33 to the side-prominent direction application of force of cam carrier 13.Accept by linkage pin 31 to be provided with roller fulcrum post 35 near the position of active force of spring 34, be provided with roller 36 at the front end of roller fulcrum post 35.Roller 36 and action bars 37 butts.The mode of action bars 37 to parallel with guide rail 25 together forms parallelogram connection-rod with driving brace 38 and driven brace 39, and length direction common and needle-bar 12 is the direction keeping parallelism of guide rail 25.Parallelogram connection-rod is accepted the driving force of motor 40, and action bars 37 can carry out and the cam carrier 13 approaching displacements of leaving.
On the connecting portion 24 of cam carrier 13 sides, comprise linkage part 29.The interlock recess 30 that is provided with on linkage part 29 has than dividing 30a and than these 2 sections of shallow portion 30b in the deep.Interlock recess 30 divide 30a to be used for common braiding than the deep, with comparing than shallow portion 30b of plating-knitted usefulness, length is shorter.When linkage pin 31 was outstanding, owing to linkage pin 31 does not fasten with attaching parts 29, thereby cam carrier 13 can not move with keeping arm 21 linkedly.Interlock state switching mechanism 22 switches to when making keeping arm 21 not with the state of cam carrier 13 interlocks, and cam carrier 13 can disconnect keeping arm 21 or yarn feeder 16 and move, and follows mobile quality to alleviate, and can promptly move.
That is, interlock state switching mechanism 22 as connecting switching device shifter, has: can control the control assembly of deformation state, the linkage pin 31 that just is arranged on cam carrier 13 or goes up and can haunt as the side in the keeping arm 21 of moving-member; With linkage part 29, be arranged on the opposing party in cam carrier 13 or the keeping arm 21, have as the interlock recess 30 of interlock with the fastening position, described interlock recess 30 is when control assembly is the predetermined deformation state, when linkage pin 31 is the state of giving prominence to, can fasten with linkage pin 31, thereby when the direction transformation of cam carrier 13, the substantial resistance to sliding of keeping arm 21 relative guide rails 25 is reduced, make along with the impact or the noise of linkage pin 31 with the conversion generation of the butt position of interlock recess 29 can reduce.
In addition, as control assembly, be the linkage pin 31 that can haunt not only, also can be swing arm, be arranged to be fit to interlock with the linkage part that fastens the position if use, then can be used as the connection switching device shifter and work.With fastening the position, be not only the such recess of interlock recess 30 as interlock, protuberance also can have same function.

Figure 13 briefly shows the another embodiment as the present invention, the control of the mobile status of the cam carrier 13 when will disconnecting with the keeping arm 21 of cam carrier 13 interlocks and the control relation of electromagnet 26.In the present embodiment, basically with the structure making knit fabric same with the embodiment of Fig. 1.In the present embodiment, be marked with identically, the explanation of its repetition is omitted with reference to label with the corresponding part of Fig. 1 embodiment.Control and Fig. 5 when cam carrier 13 and keeping arm 21 interlocks similarly carry out.In the present embodiment, shown in dotted line during the cam carrier counter-rotating, to electromagnet 28 demagnetizations.In addition, although left is when mobile and keeping arm 21 interlocks in the figure for cam carrier 13, when reversing, the situation that disconnects keeping arm 21 has been illustrated in order to move to right, when counter-rotating, also can carry out same control from right towards left certainly.In addition, when the interlock of cam carrier 13 and keeping arm 21 or disconnection, also control motor 40 certainly simultaneously, carry out the switching of the switching of interlock state switching mechanism 22.
In the control of Fig. 5, during the cam carrier counter-rotating, in order to prevent the surpassed distance of keeping arm 21, when the mobile status of cam carrier 13 is in the part in the zone of slowing down, make electromagnet 26 excitations, the steel band 28 of absorption keeping arm 21 sides carries out cam carrier 13 control that keeping arm 21 also stops when stopping, in a single day cam carrier 13 stops, and just stops the energising to electromagnet 26.Then, make cam carrier 13 counter-rotating and when mobile in the opposite direction, only otherwise, just wish to disconnect cam carrier 13 and keeping arm 21 cam carrier 13 to be moved to electromagnet 26 energising and excitations., when adopting this method, in case disconnect keeping arm 21, the stop position of keeping arm 21 may be unstable.This be because, when cam carrier slows down, after electromagnet 26 energising being made absorption affinity as the 2nd resistance to sliding begin effect, even stop energising during the cam carrier counter-rotating to electromagnet 26, also continuing magnetized state by the yoke 26b of electromagnet 26 or the residual magnetic of steel band 28, absorption affinity between cam carrier 13 and the keeping arm 21 does not disappear, when cam carrier 13 counter-rotating is mobile, with the cause of keeping arm interlock yet.In order to distinguish disconnection and the interlock of realizing 13 pairs of keeping arms 21 of cam carrier reliably, the degree that keeping arm 21 interlocks return when needing to estimate cam carrier 13 counter-rotatings moves cam carrier more than 13.
Less to the electrical current of electromagnet 26 during if cam carrier 13 slows down, the residual magnetic after then stopping to switch on is less, and the interlock in the time of can eliminating the cam carrier counter-rotating returns., exciting current diminishes, and the absorption affinity of 26 pairs of steel bands 28 of electromagnet also can diminish, even cam carrier 13 stops, keeping arm 21 also may continue to move and surpassed distance.In case keeping arm 21 surpassed distances, next for keeping arm 21 interlocks, for harmless interlock, must estimate the surpassed distance degree, make cam carrier more than 13 mobile.
When there be influencing of residual magnetic in the absorption of electromagnet 26, in any case also must strengthen the stroke that cam carrier 13 moves, the ratio of the time that does not weave in cam carrier 13 moves increased, and diminishes productivity.In order to solve problem like this, need make not remaining residual magnetic on the yoke 26b, steel band 28 of electromagnet 26.
For this reason, in the present embodiment, although with Fig. 5 similarly, adsorb to electromagnet 26 energisings in the deceleration zone of moving at cam carrier 13, but when the cam carrier counter-rotating, it flows through the electric current reverse with this energising, electromagnet 26 demagnetizations, cancellation yoke 26b.The residual magnetic of steel band 28.By so, guarantee sufficient absorption affinity when needing absorption, when cam carrier 13 disconnects with keeping arm 21, eliminated the absorption affinity that residual magnetic produces, can make the stop position of keeping arm 21 stable, can eliminate because of the invalid stroke due to the moving of cam carrier 13.
In addition, can flow through with the rightabout electric current of excitation and carry out the demagnetization of electromagnet 26.Flow through stage that time of rightabout electric current can stop at the last cam carrier 13 in the deceleration zone of cam carrier 13 or cam carrier 13 stop and reversing after the first interim any one party or two sides of acceleration region carry out.
Think that the problem of residual magnetic is by due to the material of the yoke 26b of the material of the absorption sheet of steel band 28 grades, electromagnet 26.Particularly, because steel band need be wear-resistant, so use hard material.Hard material is simultaneously easy residual magnetized hard magnetic body mostly.As steel band 28 or yoke 26b are changed into soft magnetic bodies, it is remaining that residual magnetic is difficult to., the hardness of soft magnetic bodies is low, and ABRASION RESISTANCE can be not enough.
In addition, during demagnetization, flow through and the rightabout electric current of excitation, the demagnetizing curve of magnetic flux density B by kicker magnet is shown and the relation of confining force H is even H=0 after the excitation also can make magnetized state not continue.Even flow through erasing current round about, as stop energising, also may remaining rightabout residual magnetic.As adjust the size of erasing current, the absorption affinity that rightabout residual magnetic is produced diminishes, and when cam carrier 13 counter-rotatings, keeping arm 21 interlocks is returned.Carry out demagnetization, then demagnetization reliably as the alternating current that reduces by amplitude.
Figure 14 briefly shows the control device 20 with Fig. 1, can be with the electric formation of the bi-directional drive of electromagnet 26 excitations and demagnetization.Control device 20 contains control part 120, input part 121, operating portion 122, cam carrier position detection part 123 and bi-directional drive loop 124.The realizations such as microcomputer of control part 120 by containing carried out necessary control to the braiding that straight-bar machines 11 carries out.Input part 121 inputs are to the relevant weave data of knitted fabric of straight-bar machines 11 braidings.In operating portion 122, carry out indication operation from the operator of straight-bar machines 11 etc.Cam carrier position detection part 123 detects the ad-hoc location whether cam carrier 13 is in the origin position etc. of needle-bar 12.The coil 26a energising of the 124 pairs of electromagnet 26 in bi-directional drive loop is switched excitation of carrying out to a direction and the demagnetization of carrying out round about by DC current polarity.
In straight-bar machines 11, with regard to the driving of cam carrier 13, control part 120 control cam carrier moving parts 125, when cam carrier 13 moved along needle-bar 12, control needle selection driver 125 can carry out the needle selection of knitting needle 14 etc.In addition, the solenoid 77 of control part 120 control remaining devices 19, the changeable thread-carrier 16 that whether makes is by retainer 18 interlocks.In addition, control part 120 control motors 40 can carry out the switching that is connected of keeping arm 21 and cam carrier 13.
The present invention can other variety of ways implement in the scope that does not exceed its spiritual or main feature.Therefore, all the elements of above-mentioned embodiment only only are illustrations, and scope of the present invention is shown in the scope of summary of the invention, is not subjected to the restriction of specification.In addition, distortion in the scope of summary of the invention or change all belong to scope of the present invention.
Industrial applicibility
According to the present invention, stop when mobile with the cam carrier of moving-member interlock, although move It is mobile that dynamic component will continue under effect of inertia, but because and the guide rail that stops between the additional the 1st Resistance to sliding, and stop additional the 2nd resistance to sliding between the mobile cam carrier, thereby phase For the part that stops, effect has the slip as the 1st resistance to sliding and the 2nd resistance to sliding sum Resistance can make it promptly stop. When cam carrier and the moving-member interlock, because Do not use the 2nd resistance to sliding, can make load littler. Cam carrier begins and moving part When the part interlock, become in fact the official post moving part with the 1st resistance to sliding and the 2nd resistance to sliding Part rests on the state on the guide rail, can make the resistance to sliding when acting on interlock and beginning littler, Can reduce the generation of impact or noise.
In addition, according to the present invention, can add to all-the-time stable the 1st resistance to sliding and the 2nd and slide Resistance. Because the 2nd resistance to sliding is less than the 1st resistance to sliding, thereby the movement side of cam carrier During to counter-rotating, until the interlock of relative moving part begins, the relative guide rail of moving-member is quiet End, can only make the cam carrier side shifting.
In addition, according to the present invention, owing to can use magnet control the 2nd resistance to sliding, at triangle When the seat balladeur train stops, disconnecting when the moving-member, the 2nd resistance to sliding is increased and reliable Moving-member is stopped. When the moving direction of cam carrier reverses, make the 2nd resistance to sliding slightly Less than the 1st resistance to sliding, can reduce the generation of impact or noise. In addition, the controllable the 2nd Resistance to sliding also can be greater than the 1st resistance to sliding or is little by little changed. From cam carrier disconnect and When moving-member is stopped, making the 2nd resistance to sliding make its instantaneous stopping greater than the 1st resistance to sliding, Can prevent surpassed distance. In addition, can be with the 2nd resistance to sliding when the reciprocal counter-rotating of cam carrier Little by little strengthen in the deceleration zone, and little by little reduce at acceleration region, thereby with control assembly Begin to fasten with linkage part and impact during butt is relaxed.
According to the present invention, the 2nd resistance to sliding attachment device since at cam carrier from moving-member Decelerating phase before disconnecting, to the mode of electromagnet excitation with additional the 2nd resistance to sliding, thereby energy Enough between cam carrier and moving-member, produce sufficient absorption affinity, due to absorption affinity Under the resistance to sliding, can stop from being decelerated to of cam carrier, make linkedly moving part with it Part stops.
According to the present invention, even owing to the energising that stops electromagnet, effect has electromagnetic attraction The part of kicker magnet have residual magnetic, thereby can make the magnetic of electromagnet and this moving-member The demagnetization of property attraction part is to eliminate residual magnetic. Cam carrier is under the low speed under the Reversion, When having residual magnetic, cam carrier does not separate with moving-member, moving of cam carrier During moving direction counter-rotating, moving-member also may with the cam carrier interlock. If make Triangulum sliding Exciting current to electromagnet during frame slows down reduces, so that residual when stopping to the energising of electromagnet Magnetic diminishes, and then the absorption affinity between cam carrier and the moving-member diminishes, and moving-member can Can meeting surpassed distance under inertia. If surpassed distance when moving-member slows down at cam carrier is in order to connect Get off to make cam carrier and moving-member interlock, then must estimate surpassed distance and make cam carrier Mobile, the shift motion of cam carrier increases, and cam carrier moves required time increase, Productivity can reduce. The 2nd resistance to sliding attachment device is owing to make electricity when the cam carrier counter-rotating The magnet demagnetization, thereby even the excitation of carrying out fully electromagnet so that surpassed distance not to take place, at electromagnetism Can there be residual magnetic on the iron yet, can prevents that cam carrier is undesirable when reversing The interlock of moving-member.
According to the present invention, because the 2nd resistance to sliding attachment device flows through a direction at electromagnet Electric current carry out excitation, and flow through erasing current and disappear to the rightabout of this direction Magnetic, thereby can under a direction and rightabout bi-directional drive, carry out excitation and demagnetization.
According to the present invention, during the direction transformation of cam carrier, along with control assembly and linkage part Impact or noise that the interlock of part produces with the conversion of the butt position that fastens the position are by stopping When the utilization of the surpassed distance when ending under the control of the 2nd resistance to sliding or utilization beginning the 2nd slided and hindered The control of power can reduce.
According to the present invention, for big with the occasion phase specific mass of independent use yarn guide, stop The time also bigger keeping arm of inertia, increase the resistance to sliding of effect when stopping, can making it can Stop by ground, and make the relatively substantial slip of guide rail when the direction transformation of cam carrier Resistance is littler, can reduce the generation of impact or noise.
