Abstract

The invention relates to an online checkout gear used for checking the roving tension during the high-speed spin-twisting process. The online checkout gear comprises a force sensor part; a checking end of a torsion shaft of the force sensor is fixed with a yarn guide head; a front roller yarn outlet is formed on one side of the yarn guide head, and a winding head yarn inlet is formed on the other side. The top part of the yarn guide head at the checking end is higher than a connecting line between a front roller and the yarn inlet. The invention has the advantages that the gear can be matched with the force sensor, and can be conveniently and reliably used for checking the yarn tension during the high-speed twisting movement; when the machine stops, the force sensor can be subjected to the zero adjustment under the condition that the yarn is not disconnected and under the action of a magnetic inductive loop, thereby ensuring the accuracy of the micro-tension online checkout.

Description

Fine-tension force rove testing apparatus at a high speed,

Technical field:

Patent of the present invention designs a kind of high speed fine-tension force rove testing apparatus; The concrete use becomes rove at sliver in the multistage stretching process; And in the process of twisting at a high speed; The checkout gear that keeps permanent tension force when stopping through magnetic induction loop under the situation of broken yarn not, realize zero-bit adjustment, thereby guaranteed to part a little the precision of the online detection of power rove sensor.

Background technology:

200510024019.0 Chinese invention patent; (see Fig. 5, Fig. 6), be suitable for and line 200710045540.1 Chinese invention patent discloses the power sensing of multiple automatic detection device; Rope; Bundle, stressed online these sensing devices of detection tension pick-up are being equipped with the tension force on-line automatic detection device of multi-form conducting parts applicable to difformity material to be detected in the motion of bar and sheet material, but more than several patents and patent application the form of A place, test side conducting parts is disclosed; Particularly shutting down; Under the situation about not breaking, can not adjust, thereby influence precision and indicating value that tension force detects the zero-bit of sensor.

Adopt the high accuracy ccd sensor in the market, at random the tension in the roving state being detected basic principle is to utilize ccd sensor that three kinds of states of rove are carried out detection of dynamic, as shown in Figure 3; Because rove adds that the vibration of machinery has caused rove beating heart up and down moving, thereby can't detect the on-line tension and the tension force deviation of rove in rotation twisting at a high speed in dynamically producing, and has had a strong impact on the effect that on-line tension detects at all.

Summary of the invention:

The structure of patent of the present invention comprises the sensor or the other forms of power Sensor section of above multinomial patent application; An intrinsic guide head is located in the test side that it is characterized in that power sensor torsional axis; One side of guide head links to each other with the front roller output line, and opposite side links to each other with the feed of winding head.

Advantage of the present invention is to cooperate with multiple power sensor; The tension force that is applicable to yarn in the twisting motion at a high speed easily and reliably detects; And can shut down under the situation of broken yarn not, sensor is carried out the zero-bit adjustment, thereby guaranteed the tension force accuracy of detection through magnetic induction loop, computer.

Description of drawings:

Accompanying drawing 1 is a basic structure sketch map of the present invention, and the holder loose thread that is adopted has single-ended and the both-end form; Fig. 2 is the combining form of holder loose thread and magnet and magnetic induction loop; (a-is that tension force is bigger than normal to Fig. 3 for CCD detects three kinds of states of tension force; B-is that tension force is best; C-is that tension force is less than normal); Structural representation when magnetic induction loop moved when Fig. 4 was shutdown (the holder loose thread is the both-end form); Fig. 5 is 200510024019.0 patent applications " the power sensor of automatic detection device " structural representations; Fig. 6 is 200710045540.1 patent applications " dynamic tension sensor " structural representations.Fig. 7 carries out selected flexibly structural representation for the traverse height of holder loose thread through adjustable support.Among the figure:

A 1-guide 2-holder loose thread 3-rove 4-front roller 5-feed 6-gathering sill 7-magnet 8-iron core column 9-magnetic induction loop 10-fixed flat planar 11-coil case 12-sensor torsional axis 13-square box 14-test side 15-flexure strip 16-balancing patch 17-securing member 18-support 19-adjustable support 20-contiguous block

The specific embodiment:

Close in 13 the overall structure of the present invention side of being placed in, and it is the gathering sill 6 of rove that 13 upper end two sides are closed by the side, and the rove 3 in the motion can rotate twisting and motion at a high speed in the end of guide 1.

Patent of the present invention can also be used with other forms of power sensor except that being used with " dynamic tension sensor " that be " the power sensor of automatic detection device " and 200710045540.1 patent applications of 200510024019.0 patent applications.Guide 1 a holder loose thread 2 is plating network metalwork, also other materials such as porcelain spare, ruby or rolling bearing.Gathering sill 6 is porcelain spare or metallic object.

Speed frames are in service, and magnet 7 ends of holder loose thread 2 belows are inhaled with iron core column 8 mutually.During parking, magnetic induction loop 9 is switched on power supply, and iron core column 8 is magnetized; The magnetic and former magnet 7 same sexes of generation are repelled each other, thereby hold up a holder loose thread 2, make guide 1 disengaging of rove 3 and tension force test side 14; At this moment single-chip microcomputer carries out zero-bit to sensor and adjusts automatically, and start back magnetic induction loop 9 open circuits are inhaled magnet 7 again mutually with iron core column 8; Holder loose thread 2 moves down into the original place; Rove 3 has dropped on again on the guide 1, the precision and the correctness of the online indicating value of tension force of the online detection of tension force during the adjustment of transducer zeroing has been guaranteed to produce again, and the traverse height of holder loose thread 2 is selected in the L direction through adjustable support 19 flexibly.
