Abstract

The utility model relates to a computer control device for a gang hook-drawing multi-arm machine, which is suitable for the modification of the weaving machine dobby; the lifting of an ejector rod is utilized to replace the pegs on a figure sheet to eject a poise to move; a drag hook falls to the movement position of a pull broach; the pull broach pulls the drag hook to cause a harness lever to move, and a heald frame is hoisted. The ejector rod can be controlled by an electric magnet via a pull plate at the vertical position or an oblique position; when the ejector rod lies in the vertical position, a lower part slider moving up and down eject the ejector rod to move, and replaces the peg function; the switching signal of the electric magnet comes from the EPROM storage information inserted in a special purpose computer. The information is written in according to flower types. The computer control device for a gang hook-drawing multi-arm machine has the advantages of rapid flower type conversion, low cost, reservable flower types, and has the advantage that the complex degree of the flower type can be improved, etc.

Description

Computer controller for double acting dobhy

The present invention is a kind of device for modifying by special purpose computer control double action drag hook dobbies, belongs to the weaving and knitting preparation field, mainly is applicable to the loom control with dobbies, is electromechanical integrated product.

More than 1 ten thousand of domestic dobbies, most is double action drag hook dobbies, the colored type program of this dobbies, have or not storage by the peg on the wooden pattern chain of bamboo, peg pushed poise when peg was arranged, drag hook drops to broaching tool reciprocating motion position, broaching tool pulling drag hook rotates the harness threading arm and mentions heald frame, and the method for this machinery control remained to now from the twenty's, the tired lock of technology, the new flower-shaped production preparatory period is long, last machine complexity, the machine material loss is big, and the layout of card peg is planted nail and is consumed a large amount of artificial funds, thereby look to knit the renovation of industry designs and varieties slow, can not knit system complex pattern fabric.

The objective of the invention is to solve above-mentioned deficiency, on dobbies, design a cover simple mechanism and replaced cylindrical fireworks card peg, can be on special purpose computer, insert under the control of the colored type program output signal that writes in the removable EPROM chip, make the dobbies shedding change through, weave the fabric of required colored type.

Solution of the present invention is: on dobbies cylindrical fireworks card peg position, the solenoid-actuated push rod of one cover has been installed, the push rod bottom can vertically or tilt, the push rod below has a cover to handle the slide block that moves up and down by cam or eccentric disc, make cam rotation by the connecting rod pull bar of installing on the former detent positions of dobbies three armed levers, thereby promoting slide block moves up and down in guide groove, when push rod during in obliquity slide block bump less than push rod, shedding not, when push rod during in the upright position, slide block upwards pushes push rod and has replaced the peg on the card, the jack-up poise, drag hook drops to broaching tool reciprocating motion position, and broaching tool pulling drag hook rotates the harness threading arm and mentions heald frame.And the inclination of push rod and upright position are electromagnet energising or no power control, and the signal of electromagnet derives from the colored type information that writes of inserting removable EPROM chip on the special purpose computer and controls through amplifying circuit.

Implementing transformation of the present invention makes domestic more than 1 ten thousand dobbies conversion flower type simple rapidly; shortened the new flower-shaped production preparatory period greatly; improved the complicated process of weavable cotton type; reduced cost; special purpose computer also possesses the bad cloth supervisor plus-minus of shutdown, folding of weaving process requirement and can write down a button demonstration class output, tired note output automatically, and the surplus length of warp thread coiled hair waits management data.

Below with embodiment and accompanying drawing the present invention is done specifically clearly to illustrate:

Fig. 1 is the computer controller principle schematic:

Push rod 1, (being generally 32) its position is the peg position of dobbies, push rod 1 inserts in supporting plate 2 holes, below, the supporting plate top is a sphere hole, reverse side is anti-tapered hole, push rod 1 lower end self-aligning spherical support is at supporting plate 2 sphere holes, thereby the push rod lower end can be in supporting plate deflection, supporting plate 2 belows are connected with rest pad 3,4, rest pad has the guiding (A-A section) of elongate slots (being generally 32) as push rod 1 bottom deflection, rest pad 3, form a guide groove between 4, pulling-on piece 5 slippage betwixt, be fixed with electromagnet 13(about rest pad and be generally 32) slippage in guide groove of the folding of electromagnet pulling pulling-on piece 5, pulling-on piece 5 again kink on each push rod 1, thereby handle push rod in vertical or obliquity, slide block 6 is arranged below push rod 1, roller 7 is arranged on the slide block 6, roller 7 is bearing on the cam 8, rotating promotion slide block 6 by spring 12 tension cams 8 slides up and down in the guide rail of left and right sides supporting wall plate, cam 8 is installed on the camshaft 9, camshaft 9 one ends have connecting rod 10, pull bar 11, pull bar 11 is connected the position of former ratchet on three armed levers of dobbies, and (connecting rod 10 pull bars 11 also can be used the rack-and-pinion transmission) therefore the reciprocally swinging of three armed levers back and forth rotates cam 8, pushes slide block 6 and moves up and down, when push rod 1 during in obliquity, slide block 6 motion is irrelevant with push rod 1, when push rod 1 during in the upright position slide block 6 move upward then jack-up push rod 1 upwards, push rod 1 pushes the poise of dobbies, the dobbies drag hook is fallen, and reciprocating dobbies broaching tool pulling drag hook harness threading arm is mentioned heald frame.

The vertical tilt position of push rod 1 is to be controlled by the break-make of electromagnet, the magnet switching signal is from the storage information that is inserted in the EPROM chip on the special purpose computer, to be the program that writes thereby loom multi-arm weave required pattern fabric by the colored type information of EPROM to the colored type information of EPROM, this dobbies can be joined special purpose computer and be used separately, also can use with computer multi-shuttle box shared computer.

Claims

1, a kind of device of computer control double action drag hook dobbies, control through amplifier by inserting the colored type program that writes in the removable EPROM chip on the special purpose computer, it is characterized in that one group of push rod 1 is positioned at the dobbies cylindrical fireworks, card, on the peg position, push rod 1 inserts in supporting plate 2 holes, below, the supporting plate top is a sphere hole, reverse side is anti-tapered hole, push rod 1 inserts in supporting plate 2 holes, below, the supporting plate top is a sphere hole, reverse side is anti-tapered hole, push rod 1 lower end self-aligning spherical support is on supporting plate 2 sphere holes, by pulling-on piece 5 the pullings vertical or inclination of electromagnet 13 pulling kinks on push rod 1, push rod 1 below has roller 7 is arranged on the slide block 6, roller 7 is bearing on the cam 8, by spring 12 tensions, cam 8 rotates promotion slide block 6 and slides up and down in the guide rail of left and right sides supporting wall plate, and cam 8 is installed on the camshaft 9, camshaft one end has connecting rod 10 pull bars 11, is connected the position of the former ratchet of three armed levers of dobbies.
