The specific embodiment
Be further described below in conjunction with the present invention of embodiment shown in the drawings.
Embodiment one:
Shown in accompanying drawing 1, the presser feet 110 in the trim ring device moves under the driving of motor 101.Motor 101 is installed on the motor mounting plate 107, eccentric wheel 102 is installed on the rotor of motor 101, and eccentric wheel 102 is provided with camshaft 103, and camshaft 103 connects connecting rod 104, be connected with presser feet seat 105 by pitman shaft 112 on the connecting rod 104, presser feet 110 is installed on the presser feet seat 105.Also be provided with bent road axle 113 on the presser feet seat 105.And be provided with boss in connecting rod 104 and presser feet seat 105 limits on the motor mounting plate 107, and boss is provided with slideway 108 and the bent road 109 that play the guiding role, and pitman shaft 112 is arranged in the slideway 108, and bent road axle 113 is arranged in the bent road 109.When motor 101 runnings, its rotor banding movable eccentric wheel 102 rotates, and then drives 105 motions of presser feet seat by connecting rod 104.The slideway 108 that moves through of presser feet seat 105 leads, and then presser feet 110 is moved under the guiding in bent road 109.The bent road 109 other sensors 111 that are provided with.At presser feet 110 duration of works, it moves up and down and can only move back and forth according to the track that regulates in advance.
Yet on same fabric, different material can appear, different decorative patterns, flower type, different plates, differences such as different densities, the problem of having an injection after also can occurring making mistakes between the technical problem that can't handle and presser feet and the knitting needle.When the general braiding flower type of computer flat knitting machine and dull and stereotyped fabric, can normally weave production under the tractive of high-order roller, when different wool yarn raw materials, complex pattern, the local braiding of different plate, high-order roller just can't local tractive.Presser feet is moved downward the work of location, adopt digital setting control, braided fabric is adopted knocking over and the flotation line that height is controlled the fabric coil of pressing of suiting measures to local conditions.
Computer flat knitting machine is reciprocating type braiding, and multiple decorative pattern is knitted on the same fabric with flower type, multiple density, different plates part, and the variation of pressing height that presser feet is downward also is to become thereupon.For example once toward knitting width in the variation of several density sections is also arranged, the control high and low position that presser feet that each density section changes coupling is pressed must be set so.The variation of the density section in multiple knitting width requires the same height of pressing of setting the coupling presser feet.
Therefore, design a kind of trim ring motion control system, be used for the motion of the presser feet of control trim ring device, shown in accompanying drawing 2.The trim ring motion control system comprises master controller 2, presser feet driver module 3, presser feet driving mechanism 4, position sensor 6, signal acquisition module 8, pressure sensor, feeler 9, alarm module 7, alarm element 10.
One or more position sensors 6 also are set in this trim ring motion control system, and position sensor 6 detects the position signalling of presser feet.The output of position sensor 6 feeds back to master controller 2 by signal acquisition module 8, thereby the position signalling of the presser feet of its collection is fed back to master controller 2.Master controller 2 judges whether the position signalling of presser feet conforms to preset value, thereby further controls the action of presser feet driving mechanism 4.
In this trim ring motion control system one or more pressure sensors are set also, this pressure sensor is used for gathering coil to the force value of presser feet and is translated into pressure signal.The output of pressure sensor also feeds back to master controller 2 by signal acquisition module 8.
The trim ring motion control system also is provided with feeler 9, whether this feeler 9 contacts and is converted into activation signal for detection of presser feet with improper contact component (as knitting needle etc.), the output of feeler 9 is connected with signal acquisition module 8, and activation signal feeds back to master controller 2 by signal acquisition module 8.In case presser feet and improper contact component come in contact, activation signal feeds back to master controller 2, and master controller 2 sends to presser feet driver module 3 and drives instruction locking presser feet driving mechanism 4, and sends alarm command to alarm module 7.
This trim ring motion control system can be controlled the motion of presser feet according to the movable information of detected presser feet, is applicable to the braiding of complex textile, and the presser feet kinetic stability of controlling is preferable.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
