Description
Technical field
The invention belongs to technical field of textile machine, be specifically related to a kind of rotary dobby shedding mechanism
Background technology
dobby is that the woven designs tissue signal is converted to the opening action and makes one of loom opening features of shedding motion up and down with this heald frame that drives loom, and dobby is divided into negative dobby mechanism and positive dobby structure by the difference of its opening form.
so-called negative dobby mechanism, the motion mode of its critical piece such as broaching tool, push broach and drag hook shows as reciprocating motion, and adopts form of springs to return comprehensive.Yet, along with improving constantly of generally use, the especially loom speed of shuttleless loom; Negative dobby mechanism impacts because of there being motional inertia; Not only kinetic energy consumption is big, and is difficult to ensure the steady high speed motion of loom, and for example reciprocating inertial impact force can cause the serious vibration of loom.
so-called positive dobby structure, the motion mode of its critical piece such as aforesaid broaching tool, push broach and drag hook shows as and rotatablely moves, and it is comprehensive to adopt connecting rod to return, and can abandon the aforementioned drawback of negative dobby mechanism fully.Industry claims that the latter's positive dobby structure is the rotary dobby structure in view of the above.Based on this rotary dobby structure important mechanism that is shedding device of weaving machine, therefore be referred to as rotary dobby shedding mechanism again.Undoubtedly, rotary dobby shedding mechanism be now and even from now on a period be the supporting main flow mechanism of loom.
can be by being seen in the disclosed Chinese patent document about the TECHNICAL INFORMATION SOURCES of rotary dobby shedding mechanism; Typical in invention patent mandate notification number CN1057352C (rotary dobby and the loom of equipping this type of dobby); This patent scheme has overcome the deficiency of FR-A-2540524 (loom is used rotary dobby) to a certain extent; Its technical scheme that provides is that the pallet with pivoted arm (patent is claimed pivoting arm) changes the structure with inside and outside two bearing-surfaces into, uses the angular movement amplitude (seeing the description of Fig. 1 of this patent to shown in Figure 5 and 4 page of the 3rd row of Instructions Page 3 final stage to the) that reduces pivoted arm; First mating surface of eccentric disc (patent pan of a steelyard sheet) is changed into greater than second mating surface of eccentric disc distance to the rotation of main shaft to the distance of the rotation of main shaft (patent is claimed axle); So; When first mating surface of pivoted arm and eccentric disc meshes; Pivoted arm just exceeds the sphere of action of reading device, specifically can be referring to the explanation of the Fig. 3 and the 7th page of the 4th row of the 6th page of inverse the 2nd row of specification of this patent.
are objective; Above-mentioned CN1057352C has reduced the suffered motion of pivoted arm to a certain extent effectively to be impacted; And consequent energy consumption and noise are minimized; Although this energy consumption and noise are inappreciable with respect to the whole work energy consumptions and the noise of rotary dobby structure, shown the 2nd section alleged technique effect of Instructions Page 3 after all.
still; Because rotary dobby shedding mechanism is on active service in the harsh occasion that promptly is used in high-speed overload and humid environment usually; And the state that is in the round-the-clock 24h of being continuous operation, therefore, how to prevent as much as possible and/or technical problem that the manufacturer that avoids the wearing and tearing of moving component to be not only rotary dobby shedding mechanism pays close attention to; And be the loom production firm of supporting rotary dobby shedding mechanism and even user's emphasis key factor deeply concerned of using loom; Because it is the light abrasion of moving component has then guided the wrong flower of fabric float, heavy then shorten service life as the rotary dobby structure of one of loom opening features.Yet there is the shortcoming of attending to one thing and lose sight of another in above-mentioned patent; So-called Gu this; Promptly achievement is arranged for reducing the energy consumption and the noise that are prone to people ignore; And so-called mistake that, promptly lose for the wearing and tearing of the inner bearing face of the pallet of first mating surface of disc and aforesaid pivoted arm biased because; In the use of reality, the trouble that the effect of aforesaid energy-saving and noise-reducing and the latter cause because of wearing and tearing (rotary dobby shedding mechanism service life short and cause the loom weaving efficiency to descend and fabric float) loses more than gain.
Can know by the disclosed technology contents of CN1057352C: when disc rotates; Outwards open passively with the pivoted arm that first mating surface of eccentric disc is meshed, there is skimming wear in both in opening procedure, if press the action probability of the continuous start of the speed of 1000r/min and average 50%; Then eccentric disc moves 7.2 ten thousand times every day; The pivoted arm of a pair of alternating movement respectively is 3.6 ten thousand times, so how long need not, eccentric disc and pivoted arm all decrease; In the process of eccentric disc and pivoted arm swing; Because the pallet of pivoted arm and the contact-making surface of eccentric disc are the some contact form (Fig. 4 and Fig. 5 of this patent show) that is similar to W shape; Therefore contact point shows as the great-jump-forward conversion; It is coherent that great-jump-forward conversion meeting is lost action, thus the uneven wear of aggravation faying face; Owing to be subject to the rotary dobby shedding mechanism of compact conformation and the contact form of aforesaid W shape, therefore actual effective contact area is very little, is about 2 * 2 ㎜ (4 ㎜

) scope, again since the pulling force that is connected in the spring on the pivoted arm usually more than 50N, and the motion that has superposeed bigger impacts, and therefore is difficult to rely on aforesaid some contact to bear the pulling force of spring and the motion impulsive force of following, thereby makes wearing and tearing more become serious.Finally, must require rotary dobby shedding mechanism to have harsh but actual implacable angle positioning accuracy if above-mentioned wearing and tearing are accumulate to a certain degree, then certainly will cause opening to botch routines, can't ensure the quality of fabric.
therefore; How at energy-saving and noise-reducing and avoid wearing and tearing and find rational equalization point between the two; Become industry to pay close attention to for a long time and the phase is got the technical problem of solution, yet, in disclosed patent and non-patent literature, all do not provide corresponding enlightenment.The applicant does positive and useful exploration and trial for this reason, and under the secrecy provision of strictness, proves practicable through experiment, and the technical scheme that will introduce below produces under this background

Fig. 1 and Fig. 2 please referring to Fig. 3 and be continued to combine in
; Technical essential as technical scheme provided by the invention: the shape that the shaped design of aforesaid first, second eccentric disc field of conjugate action 32,33 is become the semi arch concave surface; Adaptably first, second swing arm field of conjugate action 62,72 is designed to the shape of semi arch convex surface therewith, and the radial design of semi arch concave surface is become to equate with the radius of semi arch convex surface.Though Fig. 3 has illustrated the situation that the second swing arm field of conjugate action 72 of secondary signal swing arm 7 cooperates with the second eccentric disc field of conjugate action 33 of eccentric disc 3; But the understanding of the situation that can't match with the first eccentric disc field of conjugate action 32 of eccentric disc 3 to the first swing arm field of conjugate action 62 of the first signal swing arm 6 produces puzzled, because both operating principles are similar.In addition; The applicant is that first distance B 1 between the pivot of main shaft 1 is designed to and second eccentric disc is nibbled the second distance D2 between the pivot that face 33 is main shaft 1 to the rotation of main shaft 1 to the rotation of main shaft 1 with the first eccentric disc field of conjugate action 32, just makes first distance B 1 equal second distance D2 (Fig. 2 shows).So the advantage of design is: under the prerequisite of the amplitude of the angular movement that does not increase first, second signal swing arm 6,7; Make with eccentric disc 3 on first, second eccentric disc acting surface each other of nibbling first, second swing arm field of conjugate action 62,72 that face 32,33 is meshed constitute arc form; Thereby can reduce the degree of wear of faying face significantly, make the required angle positioning accuracy of rotary dobby shedding mechanism be able to significantly improve.Because the radius of aforesaid semi arch concave surface equates (both wait radius) with the radius of semi arch convex surface; Thereby both effective contacts area have been ensured; When producing slip relatively when eccentric disc 3 rotations and with the first signal swing arm 6 or secondary signal swing arm 7; Be not difficult to find out that this relative slip is in to be carried out under the level and smooth relatively situation that contact point changes successively continuously, the position changes even and unidirectional variation, compare that contact point under the field of conjugate action form of aforesaid W shape jumps, the situation of change in location sudden change is even more ideal; Therefore alleviated the degree of wear separately respectively, and noise reduces relatively also.Because, in case wearing and tearing then can cause the positioning accuracy of eccentric disc 3 inaccurate, thereby further cause the flange 51 of clutch pawl 5 to be difficult to first groove 41 or second groove 42 of centering flower keyboard 4, finally cause opening to be botched routines.In addition, no matter be, make the positional precision assurance that more is easy to get to the processing of the semi arch concave surface of first, second eccentric disc field of conjugate action 32,33 or to the processing of the semi arch convex surface of first, second swing arm field of conjugate action 62,72 with detect all very conveniently.As long as the center of circle of semi arch concave surface and the center of circle of double arc convex surface are located correctly, radius error is almost nil to the influence of the positioning accuracy of eccentric disc 3 so, does not promptly produce any influence.If yet the technological prejudice in the prior art is not overcome and adopt the field of conjugate action that is similar to W shape such as CN1057352C instruction, can't embody aforesaid technique effect.Also have, aforesaid first, second distance B 1, D2 are designed to be equal to each other, can embody and allegedly in the superincumbent technique effect of the applicant hurdle reduce power consumption and use the strong point of energy savings.Because; When first distance B 1 equaled second distance D2, when inhaling the touching pawl 83 and touch second of secondary signal swing arm 7 and inhale iron swing arm haptic element 73 of iron swing arm 8, the second swing arm field of conjugate action 72 separated with the second eccentric disc field of conjugate action 33; So, can extra increase energy consumption when eccentric disc 3 rotates; Otherwise; If second distance D2 is designed to greater than first distance B 1; So when inhaling the touching pawl 83 and do not touch second of secondary signal swing arm 7 and inhale iron swing arm haptic element 73 of iron swing arm 8; Nibble face 33 and still be in engagement thereby make second swing arm nibble face 72 and second eccentric disc, so eccentric disc 3 can extra increase outwards be opened the energy of secondary signal swing arm 7 when rotating.
applicant it may be noted that the foregoing description is not to the present invention program's restriction example, the version that for example can use first, second swing arm field of conjugate action 62,72 of first, second signal swing arm 6,7 instead roller.With the first signal swing arm 6 is example, through roller shaft one roller is set rotationally above that, and roller matches with the semi arch concave surface, and the radius of roller equates that with the radius of semi arch concave surface this scheme can embody aforesaid technique effect equally.
applicant sketches operation principle of the present invention, and loom power makes main shaft 1 and flower keyboard 4 motions that are contained on the main shaft 1 through the effect of cam mechanism.After electromagnet 82 receives signal, produce magnetic, will inhale iron swing arm 8 adhesives; In bottom process, inhale iron swing arm 8 and overcome self spring force, make it touch pawl 83 and act on the first suction iron swing arm haptic element 63 by the first signal swing arm 6 shown in Figure 1; First signal pendulum 6 overcomes the spring force of first back-moving spring 64, makes the first swing arm field of conjugate action 62 of the first signal swing arm 6 break away from the first eccentric disc field of conjugate action 32, at this moment; Clutch pawl 5 is under the spring force effect of reaction spring 521, and first groove, 41 tablings on its flange 51 and the flower keyboard 4 are coupled as one clutch pawl 5 and flower keyboard 4; Under the drive of flower keyboard 4, drive eccentric disc 3 and rotate together, drive swing arm 2 motions by eccentric disc 3; Realize that the shedding arm is the regular swing of hinged pivoted arm 221, finally drive heald frame and realize the upper and lower opening motion.When electromagnet 82 was not received signal, this moment was not because electromagnet 83 dead electricity promptly produce magnetic, inhaled iron swing arm 8 under the effect of self spring force; Make it touch pawl 83 and leave the aforesaid first suction iron swing arm haptic element 63, and act on secondary signal swing arm 7, therefore the first signal swing arm 6 is under the effect of first back-moving spring 64; End with first swing arm field of conjugate action 62 of the first signal swing arm 6 is tightly pushed down clutch pawl 5, and the flange 51 of clutch pawl 5 is separated with first groove 41 of flower keyboard 4, and eccentric disc 3 is in released state with flower keyboard 4; When flower keyboard 4 rotates; Eccentric disc 3 no longer rotates, and the heald frame transfixion does not realize the opening action.
In sum, technical scheme provided by the invention has overcome the shortcoming in the prior art, has accomplished invention task and objective and has embodied beyond thought technique effect
