Abstract
The invention discloses a serial control circuit for shuttles of a seamless underwear machine. The serial control circuit comprises a control board, wherein a control circuit and a level shifter for differential transmission are arranged on the control board, the front portion of the control board is connected with the front end of a first path of shuttle through cables, and the rear portion of the control board is connected with a final path of shuttle through cables; the shuttles are serially connected and sequentially cascaded, namely the first path of shuttle is connected with the second path of the shuttle, the second path of the shuttle is connected with a third path of shuttle, and the rest can be connected in the same manner; and a driving board is installed in each shuttle part, and a level shifter for differential transmission, a shifting register, a solenoid valve driving chip and a voltage-stabilized power source circuit are arranged on the driving board. The serial mode adopts high-speed serial data with differential technology transmission, and series-to-parallel transformation can be achieved by means of the shifting register technology. By means of the serial control circuit for the shuttles of the seamless underwear machine, only four pairs of double twisted pair cables and a pair of power source wires are needed, the number of the cables is greatly reduced, and the wiring is simple, attractive, economic and reliable.
Description
Technical field
The present invention relates to technical field of knitting machinery, especially relate to a kind of Serial Control loop for the seamless underwear machine shuttle.
Background technology
In existing technology, mostly the control loop that is used for the seamless underwear machine shuttle be parallel control to be characterized in that solenoid valve quantity is large, and each shuttle disposes 15 solenoid valves, and the quantity that amounts to the shuttle solenoid valve be 15 with the product of way.As shown in Figure 1, on a control panel, connect the dc power supply of 24V, and have the driving chip of control circuit and solenoid valve at control panel, and on this control panel, parallel join multichannel shuttle, each road shuttle is furnished with 15 solenoid valves, each solenoid valve need to connect a signal line, and the common return cable, and described output signal and solenoid valve are corresponding one by one.But the control loop of this parallel mode can cause the quantity of system cable a lot, has complicated, in disorder, the high in cost of production shortcoming of wiring.
Summary of the invention
In order to address the above problem, to the invention provides a kind of Serial Control loop for the seamless underwear machine shuttle, thereby reach the purpose that reduces number of cables.
For this reason, adopt following technical scheme: a kind of Serial Control loop for the seamless underwear machine shuttle, it is characterized in that: it comprises a control panel, is provided with the level translator of control circuit and differential transfer at control panel; Control panel is anterior to be connected by cable with first via shuttle front end, and the control panel rear portion is connected by cable with last road shuttle; Wherein connected in series between each road shuttle, successively cascade, namely first via shuttle connects the second the tunnel, the second tunnel and connects Third Road, and by that analogy; At each shuttle component locations one drive plate is installed, described drive plate is provided with level translator, shift register, solenoid-driven chip, the voltage-stabilized power supply circuit of differential transfer.
Further, the dc power supply that all is communicated with 24V at control panel and first via shuttle front end.
Further, whole system is transmitted 4 road signals in transmission course: chip selection signal, clock signal, data input signal, data output signal; Described chip selection signal has low level and high level two states.
The data output signal of control panel (SDO) is as the data output signal (SDI) of first via shuttle drive plate, the data output signal (SDO) of first via shuttle drive plate is as the data output signal (SDI) of the No. the second shuttle drive plate, successively cascade, the data output signal (SDO) of last road shuttle drive plate is as the data output signal (SDI) of control panel.Chip selection signal (CS) low level represents to allow data transmission, during by low uprising serial data stream is converted to parallel data and latchs.Clock signal (CLK) is the synchronous serial data bit clock that drifts.The solenoid-driven chip has protection and self-diagnostic function, can and accomplish to control the synchronous transmission of data with the feedback of status of each road shuttle.Serial mode has adopted differential technique transmitting high speed serial data, realizes string and conversion by the shift register technology.The method only needs 4 pairs of twisted-pair feeders, and a pair of power lead, has greatly reduced cable quantity, and it is simple, attractive in appearance, economical, reliable to connect up.
