Abstract
The present invention relates to an intermittent guiding shuttle driving device for a shuttle loom. A set of parallel graduation cams are driven by the rotating power of a shuttle loom, and are used for driving a chain wheel set in an intermittent mode, and the chain wheel set is used for driving a movable seat to carry out the intermittent displacement in a reciprocating mode; the movable seat is set to be temporarily static on the limiting position of the displacement; thus, the movable seat can be used for picking action by an amplifying mechanism; the arrangement of the parallel graduation cams enables the movable seat to stay for a static time period when the movable seat moves to the limiting position to be helpful for beating-up movement.
Description
The present invention relates to a kind of loom drive unit, more particularly is a kind of intermittent shuttle guide driving device of loom.
Loom is at weaving processing industry a kind of considerable machining machine and tool of can saying so, relevant for many years manufacturer also constantly drops into manpower, material resources are studied and are improved, design that bigger breakthrough promptly is " magnetic control shuttle loom " in recent years, it lies in shuttle body and is provided with magnet, fly shuttle (shuttle) and do displacement in slay (slay) top and can drive by the displacement of shuttle body, to finish picking campaign (picking motion), this design can be arranged on the driving mechanism that flies shuttle the slay below fully, what can not have influence on the action that flies shuttle or graticule interweaves its true tool progressive and practicality.
If further the picking mechanism of aforesaid magnetic control shuttle loom is analyzed as can be known, it flies shuttle and does displacement by the shuttle body of slay below by the magnetic force drive on slay, the mode of its motion is by the static certain speed that accelerates to, and then promptly slow down, stop at the other end place of slay at last, fly shuttle static a period of time of meeting at this place, for carrying out beating motion (beating motion), after beating motion is finished, fly shuttle and drive throwing in the opposite direction by shuttle body again, it also is to slow down rapidly after adding to certain speed again, and stop at the first end place of slay, carry out the beating motion of another time then, so the repetitiousness operation can be carried out weaving operation.
By existing shuttle guide driving device as seen, it is that the rotary power of loom power source (motor) is direct through behind the suitable transmission mechanism, do reciprocal rotation in order to drive a belt wheel, thereby drive shuttle body and in slay, do to come and go displacement, this type of mechanism continues to use the transmission mechanism of traditional loom mostly, that is it is that utilization cam or similar transmission mechanism convert rotational action to shuttle rotation mostly, do linear round displacement and drive shuttle body via belt wheel, this type of mechanism is subject to the restriction on the structural arrangements, its manner of execution all presents the pattern of similar " simple harmonic motion (simple harmonic motion) ", and can't fly shuttle when moving to the slay end positions, " static " state of suitable period is provided, for carrying out beating motion, that is in the picking campaign that flies shuttle, there is not so-called " static " time fully, this makes that promptly beating motion is to carry out in the moment that flies shuttle transition shifts direction, and it is quite nervous in the collocation utilization of time.
In loom design now, how can effectively promote its process velocity, become a considerable problem, that is the speed of its picking campaign and beating motion constantly is required to promote, on existing loom structural arrangements, its drive unit follows the loom from traditional type, if promote its running speed again, then it flies shuttle leaves warp in the picking campaign scope, oppositely enter the period between the scope of warp then again, be not enough to finish beating motion, some manufacturer is in order to solve this problem, meeting painstakingly extends the length of slay, and then growth flies the displacement stroke of shuttle, flying shuttle so as to increase slows down in the slay end positions, 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 are desirable absolutely not for this because animal economy broaden must be bigger than the branch parsec influence of process velocity.
If just perform an analysis on the technology, fly shuttle needed certain motion mode when carrying out the picking campaign and should be:
That is flying shuttle when being decelerated to halted state, should keep suitable quiescent time, be beneficial to the carrying out of beating motion, and then oppositely acceleration of row, that is in the process of its picking campaign, flying shuttle when arriving at the slay end positions, the inactive state that must have an appropriate time, can realistic operation required, so when promoting the running speed of loom, can guarantee the accurate operation of beating motion, unlikely and picking campaign is disturbed.
The inventor supervises in existing shuttle guide driving device of shuttle loom and flies shuttle when carrying out the picking campaign in driving, fly all to fail to provide appropriate inactive state when shuttle is moved to the slay two ends at it, cause loom when hoisting velocity, mutual interference takes place in picking campaign and beating motion, that is it can make speed lifting that quite strict restriction is arranged, and the improved efficiency of loom has been constituted restriction, be to study improvement at this disappearance for this reason, after constantly testing and improveing, develop the present invention who value on the true tool industry finally.
Main purpose of the present invention is: the intermittent shuttle guide driving device that a kind of loom is provided, setting by parallel graduated cam, can when moving seat and move to extreme position, stop one period quiescent time, and can allow the shuttle body on the loom do round displacement in order to beating motion.
