Abstract
The present invention relates to a weft inserting device of a shuttle loom using parallel graduation cams for driving a stroke adjusting mechanism. A set of parallel graduation cams are driven by the rotating power of a shuttle loom, and are used for driving the stroke adjusting mechanism in an intermittent mode; the stroke adjusting mechanism is used for driving a movable seat to carry out the intermittent displacement of a reciprocating type, and the movable seat is set to be temporarily static on the limiting position of the displacement; thus, the displacement of the movable seat can be used for picking action by an amplifying mechanism; thus, when the movable seat moves to the limiting position, the movable seat can stay for a static time period to be helpful for carrying out the beating-up movement.
Description
The present invention relates to a kind of loom weft insertion device, especially is the loom weft insertion device of relevant a kind of parallel graduated cam driven stroke regulating mechanism.
At textile limit loom a kind of considerable processing machine of can saying so, relevant for many years manufacturer also constantly drops into human and material resources and studies and improve, design that bigger breakthrough promptly is " magnetic control shuttle loom " in recent years, it is to be provided with magnet in shuttle body, on slay, do displacement and can drive shuttle by the displacement of shuttle body, to finish the picking campaign, this design can be arranged on the driving mechanism of shuttle the slay below fully, can not have influence on the motion of shuttle or interweaving of graticule, its true tool progressive and practicality.
If further the picking mechanism of aforesaid magnetic control shuttle loom is analyzed as can be known, its shuttle is done displacement by the shuttle body of slay below by the magnetic force drive on Button Block, the mode of its motion is by the static certain speed that accelerates to, and then slow down rapidly, stop at the other end of slay at last, in this place's shuttle static a period of time of meeting, for carrying out beating motion, after beating motion is finished, shuttle is driven by shuttle body and invests opposite direction, and it also is to slow down rapidly after accelerating to certain speed again, and stops at first end of slay, carry out the beating motion of another time then, in operation so repeatedly, weave operation.
See it by existing shuttle guide driving device, it is the rotary power of loom power source (motor) directly to be driven a belt wheel through suitable transmission mechanism do back and forth to rotate, in slay, do to come and go displacement to drive shuttle body, this type of mechanism continues to use the transmission mechanism of traditional loom mostly, that is it is to utilize cam mostly, crank or similar transmission mechanism convert reciprocal rotation to rotatablely moving, by to drive shuttle body through belt wheel, make it to do straight line and come and go displacement, this type of mechanism is subjected to structural limitations, its manner of execution all presents the pattern of a kind of similar " simple harmonic motion ", and can't when shuttle moves to the slay end positions, provide suitable " static " time to carry out for beating motion, that is in the picking campaign of shuttle, there is not so-called " static " time fully, this makes that promptly beating motion is to carry out in the moment of shuttle transition shifts direction, and it is promptly quite narrow in the collocation utilization of time.
In current loom design, how to promote process velocity effectively, become a considerable problem, that is the speed of its picking campaign and beating motion constantly is required to promote, only on existing loom structure, its drive unit still follows traditional loom form, if promote the speed of service again, then its shuttle leaves the scope of warp in the picking movement travel, oppositely enter the fragment period between the scope of warp then again, be not enough to finish beating motion already, some manufacturer is in order to solve this problem, meeting painstakingly extends the length of slay, and then the displacement stroke of growth shuttle, slow down in the slay end positions so as to increasing shuttle, stop (turning to), the blanking time of quickening, carry out beating motion so that strive for reasonable time length, but will inevitably making the associated mechanisms specification of picking campaign strengthen, it (increases such as the cam specification, the slay width broadens), also can make simultaneously the integral width of loom increase, production firm or user find pleasure in and see absolutely not for these, influence must be far more than the every minute and second battle of process velocity in one's power because animal economy broadens.
If just perform an analysis on the technology, shuttle needed motion mode when carrying out the picking campaign should be:
That is when shuttle is decelerated to halted state, should keep the quiescent time of suitable length, be beneficial to the carrying out of beating motion, and then oppositely acceleration of row, that is in the process of its picking campaign, when shuttle arrives at the slay end positions, must have one period suitable quiescent time, needs that can realistic operation are so when promoting the running speed of loom, can guarantee the accurate operation of beating motion, unlikely and picking campaign is disturbed.
The inventor because existing shuttle guide driving device of shuttle loom when driving shuttle and carry out the picking campaign, when being moved to the slay two ends, its shuttle all fails to provide appropriate quiescent time, cause loom when hoisting velocity, picking campaign and beating motion generation mutual interference mutually, even also the lifting to speed has quite strict restriction, and the improved efficiency of loom has been constituted restriction, be to study improvement at this shortcoming for this reason, through test constantly and improvement, developed the tatting weft insertion device of value on the true tool industry finally.
The objective of the invention is to: the loom weft insertion device that a kind of parallel graduated cam driven stroke regulating mechanism is provided, it is that rotary power with loom drives one group of parallel graduated cam, drive stroke regulating mechanism by this group parallel graduated cam in intermittent mode, drive mobile seat by stroke regulating mechanism again and carry out intermittent reciprocating type displacement, and set this move the seat temporarily static at the extreme position of displacement, so can carry out picking movement through enlarger by moving seat, setting by parallel graduated cam, can be when mobile seat moves to extreme position, stop one period quiescent time in order to beating motion, and can allow the picking campaign of loom and the beating motion can be more accurate.
Another object of the present invention is to: the loom weft insertion device that a kind of parallel graduated cam driven stroke regulating mechanism is provided, wherein the stroke regulating mechanism that is driven by parallel graduated cam can provide and move the different degree of displacement of seat, that is be pivoted according to the drive block that moves seat and be connected the different location of stroke regulating mechanism, can provide and move the different displacement stroke of seat, and can be applicable to different types.
Another purpose of the present invention is: the loom weft insertion device that a kind of parallel graduated cam driven stroke regulating mechanism is provided, wherein enlarger is an assembly pulley, it is to be made of the movable pulley group of forward and backward assembly pulley with the centre, leading the shuttle stay cord is set around between forward and backward assembly pulley and the middle movable pulley group, and the movable pulley group is erected at and moves on the seat, when mobile seat is subjected to displacement, can displacement be amplified by enlarger, and can carry out picking movement by leading the shuttle stay cord.
Purpose of the present invention is achieved in that
