Abstract
The utility model relates to a first-spinning position signal collecting device of a spinning machine, which comprises a semicircular cam and a signal collecting sensor, wherein the semicircular cam is arranged on a worm-wheel shaft arranged below a headend grade-raising support claw mechanism of the spinning machine, the signal collecting sensor is corresponding to the semicircular cam and is electrically connected with a control system, the semicircular cam is made of nylon materials, a plurality of permanent magnets which are evenly distributed are embedded on a circular arc of the semicircular cam, and the signal collecting sensor is of a Hall sensor. When the spinning machine begins to spin yarns, the permanent magnets on the circular arc of the semicircular nylon cam can induce the Hall sensor and send out induction signals, as the distance between two permanent magnets are smaller, the Hall sensor can be ensured to always output signals when the Hall sensor moves between two permanent magnets, thereby the normal operation of the spinning machine can be realized through the control system.
Description
Technical field
The utility model relates to a kind of fine spining machine to be begun to spin the position signal acquisition device, belongs to automation field.
Background technology
The known fine spining machine beginning is spun the position signal acquisition device and is mounted in fine spining machine headstock level and rises the semicircle metal cam on the support claw mechanism below worm-wheel shaft and form with the corresponding travel switch that is installed on the headstock wallboard by support of semicircle metal cam, and travel switch links to each other with the control system of fine spining machine as signaling device.When fine spining machine began to spin, semicircle metal cam contacted with travel switch, and travel switch is in closure state all the time and sends a high level signal, and fine spining machine normally drives to move; When fine spining machine finished spinning, travel switch disconnected, and fine spining machine is finished the control procedure of doffing.Because existing travel switch is a contact, and whole again spinning process contact with semi-circular shape metal cam all the time, caused the trip switch to damage easily, the increasing of working service cost.
The utility model content
The purpose of this utility model is at above technical scheme, provides the low fine spining machine beginning of a kind of long service life, working service convenience and cost to spin the position signal acquisition device.
For addressing the above problem, the utility model adopts following technical scheme: the fine spining machine beginning is spun the position signal acquisition device, comprise that radius is the half cam of 86mm, the signals collecting sensor, half cam is installed in fine spining machine headstock level and rises on the support claw mechanism below worm-wheel shaft, the signals collecting sensor is corresponding with the position of half cam, the signals collecting sensor is electrically connected with control system, it is characterized in that: half cam adopts nylon material to make, be embedded with several equally distributed permanent magnets on the circular arc of half cam, the signals collecting sensor is a Hall element.
A kind of concrete prioritization scheme of permanent magnet is embedded with 19 equally distributed permanent magnets on the circular arc of half cam.
A kind of concrete prioritization scheme of Hall element, Hall element comprises a pulse switch pipe, first resistance, second resistance, the 3rd resistance, Hall element, light emitting diode, the emitter stage of pulse switch pipe connects power supply, current collection is output very, base stage is through second resistance and Hall element ground connection, the contact of second resistance and Hall element connects power supply through first resistance, and colelctor electrode is through light emitting diode, the 3rd resistance eutral grounding.
Beneficial effect: the utility model adopts technique scheme, have the following advantages: when fine spining machine begins to spin, equally distributed 19 permanent magnets are responded to Hall element and are sent induced signal on the semicircle nylon cam circular arc, distance between two permanent magnets is smaller, Hall element is between two permanent magnets when mobile, can guarantee that Hall element has signal output always, normally drive by control system realization fine spining machine, because it is big to pass the adjustment distance of Hall sensor, therefore in use be easy to adjust, Hall element stable performance simultaneously, long service life, price is low, is convenient to promote; And half cam only plays the effect of support fixation permanent magnet, adopts nylon material to make handling ease, low cost of manufacture.Through experiment, use fine spining machine beginning of this structure to spin the position signal acquisition device and spin the position signal acquisition device with the beginning of former travel switch formula and compare, every fine spining machine reduces cost more than 100 yuan.
Below in conjunction with drawings and Examples the utility model is elaborated.
