Description
Technical field
The utility model relates to flat machine control technology field, relates in particular to the control system of a kind of straight-bar machines from the formula of race yarn mouth.
Background technology
Yarn mouth is the structure of drawing yarn-guide mouth and enter braiding.Traditional straight-bar machines, the movement of yarn mouth is to complete by the mobile folding that coordinates yarn mouth electromagnet of head.In the time that needs move right to position B No. 1 Sha Zuicong position A, need following steps:
(1) head moves to yarn mouth left side No. 1.
(2) yarn mouth electromagnet is laid, and head continues mobile.In the time that head moves to A position, yarn mouth electromagnet can drive yarn mouth synchronizing moving.
(3) in the time that head moves to the left side certain distance of B position, yarn mouth electromagnet moves again, and yarn mouth and head depart from.Head continues operation, and yarn mouth runs to B position by inertia.
Action has several shortcomings like this:
(1) movement of yarn mouth, needs the extra stroke of head.In the technique of multi-color braiding, sometimes even need the time of several times of the expenses of spending more.
(2) actuation time of conventional yarn mouth electromagnet at present, need time of tens ms.And the maximum speed of head can reach 1.0m/s, this error of taking to be can not ignore, and need to calculate real-time handpiece speed and determine this yarn mouth action lead.An each band yarn mouth head lead, waste strokes of running more.And the error of calculation of real-time speed, and deviation actuation time of yarn mouth electromagnet, all can affect the precision that yarn mouth is parked.And the deviation of the position that yarn mouth is parked can cause that hook is less than line, the wrong line of hook, the serious knitting needle that even can break, infringement arranges.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, the control system of a kind of straight-bar machines from the formula of race yarn mouth is provided, by introducing servo control technique, each yarn mouth is driven with a servomotor controller, directly moved by the mainboard control yarn mouth servomotor that says the word.
The utility model is achieved through the following technical solutions: a kind of straight-bar machines is from the control system of the formula of race yarn mouth, comprise straight-bar machines master control borad, flat-knitting machine head controller, head position coder on flat-knitting machine head main servo device and flat-knitting machine head main servo device, the automatic yarn mouth control module that several are separate, described straight-bar machines master control borad respectively with flat-knitting machine head controller, flat-knitting machine head main servo device, the communication of head position coder connects, described automatic yarn mouth control module is connected with the communication of straight-bar machines master control borad through CAN bus parallel connection, and head position coder is directly connected to each separate automatic yarn mouth control module, and each automatic yarn mouth control module is by order and motion control unit, servomotor controller, servomotor is connection composition successively, described driven by servomotor is run formula yarn mouth certainly along guide rail movement, and synchronize with flat-knitting machine head when mobile and braiding and follow two kinds of operational modes of movement before running formula yarn mouth to have braiding on guide rail.
Further, described straight-bar machines master control borad is analyzed and generating run control instruction the braiding flower type of input.
Further, described flat-knitting machine head main servo device receives straight-bar machines master control borad operation control instruction guiding flat-knitting machine head and moves, and the head position coder feedback flat-knitting machine head position signalling on flat-knitting machine head main servo device is to straight-bar machines master control borad.
Further, the order of described automatic yarn mouth control module and motion control unit run formula yarn mouth status signal to straight-bar machines master control borad certainly by CAN bus reception straight-bar machines master control borad operation control instruction and by CAN bus feedback, and the order of yarn mouth control module is connected and reads in real time flat-knitting machine head position signalling with the communication of head position coder with motion control unit automatically.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by introducing servo control technique, each yarn mouth is driven with a servomotor controller, directly say the word and control yarn mouth servomotor and move by mainboard, the operation of yarn mouth is efficient, avoid the invalid operation of yarn mouth that actuation time, error caused in the past, yarn mouth Position Control is accurate, avoid because of yarn mouth stand deviation, cause that yarn mouth hook is less than line, the wrong line of hook, the phenomenon that even can break knitting needle occurs, guarantee equipment security of operation, and improve operating efficiency, yarn mouth can be along with the increase and decrease that needs of braiding flower type, exaptation is strong, easy to use.
