Problems solved by technology

[0002] In the computerized flat knitting needle selection system, it can be divided into a six-stage needle selection system and an eight-stage needle selection system in terms of the number of segments. At present, the two systems cannot be used in common, that is, the hardware and software parts of the two systems cannot be used in common. In terms of control methods, it can be divided into hardware needle selection processing system and software needle selection processing system. Because various needle selectors have different internal resistances and are prone to heat, after passing through the hardware needle selection processing system, random needle selection, missed selection, and multiple When the selection occurs, the software needle selection processing system is only applicable to the eight-segment needle selection, not to the six-segment needle selection

Embodiment 1

[0010] Embodiment 1: with reference to attached figure 1 and 2 . The computerized flat knitting needle selection control system includes a host computer 1, the signal output terminal of the host computer 1 is connected to the signal input terminal of the control board 2, the signal output terminal of the control board 2 is connected to the signal input terminal of the needle selection PC board 3, and the needle selection The signal output terminal of the PC board 3 is connected to the needle selector 4 and controls the needle selection electromagnet to make the needle selector move. By setting the control parameters of the upper computer 1, select six-stage needle selection or eight-stage needle selection, and then transmit the information to the control board 2 through the CAN bus. To the control board 2, the control board 2 processes the received signal, uses the PWM control method to control the needle selection PC board 3, and the needle selection PC board 3 controls the...

Embodiment 2

[0012] Embodiment 2: On the basis of Embodiment 1, the new needle selection control method determines whether to select six-segment needle selection or eight-segment needle selection by setting the control parameters of the upper computer 1, and then sends the selected information to the control board 2. When the machine head is running, the upper computer 1 sends the entire set of needle selection signals to the control board 2, and the control board processes the received signals, and uses PWM control to control the needle selection PC board 3, and finally the needle selection PC board To control the needle selection electromagnet to make the needle selection piece move.

[0013] First, send a group of continuous power-on signals to the needle selector to control the needle selection electromagnet, so that it can fully move, and notify the PWM control board 2 of the setting of this period of time through the setting of the host computer 1, after a period of time , the needle...

Abstract

The invention relates to needle selection control system and control method of a computerized flat knitting machine and a control method, which ensure that a six-section needle selection system and an eight-section needle selection system share same hardware, and needle selection can be achieved through software. The needle selection control system of the computerized flat knitting machine comprises a host computer, wherein a signal output end of the host computer is connected with a signal input end of a control board; a signal output end of the control board is connected with a signal input end of a needle selection PC board; and a signal output end of the PC board is connected with a needle selector and controls a needle selection electromagnet to enable a needle selection piece to act. The invention has the advantages that the needle selection control system of the computerized flat knitting machine ensures that the six-section needle selection and the eight-section needle selection can share the same hardware, and the needle selection system can be selected through software so as to ensure that the phenomena of needle disorder, selection omission, excessive selection and the like can not occur.

Description

technical field [0001] The invention relates to a computerized flat knitting machine needle selection control system and a control method that can share one hardware with six-stage needle selection and eight-stage needle selection, and can select needles through software, and belongs to the field of computerized flat knitting machine manufacturing. Background technique [0002] In the computerized flat knitting needle selection system, it can be divided into a six-stage needle selection system and an eight-stage needle selection system in terms of the number of segments. At present, the two systems cannot be used in common, that is, the hardware and software parts of the two systems cannot be used in common. In terms of control methods, it can be divided into hardware needle selection processing system and software needle selection processing system. Because various needle selectors have different internal resistances and are prone to heat, after passing through the hardware ...
