Embodiment

[0024] Embodiment: A kind of high-speed reversing control method of flat knitting machine head, such as figure 2 As shown, the steps include:

[0025] Step 1: Data reading: the main control module reads the movement data of the next stroke of the machine head from the storage module of the human-computer interaction module (ARM), parses and stores the result in the array module of the human-computer interaction module; The computer interaction module includes a FLASH module and a RAM module; the storage module of the human-computer interaction module is a FLASH module, and the array module of the human-computer interaction module is a RAM module; the main control module adopts a module with a digital signal processor DSP as the core processor.

[0026] Step 2: Execute the reversing action: the main control module sends an action instruction to the head module through the field bus CAN, and the co-processing module (FPGA) on the head performs the reversing action according to ...

Abstract

The invention relates to a flat knitting machine nose reversing control method and a control system thereof. The method includes the following steps: 1, data is read; 2, reversing action is executed; 3, back torque is adaptively adjusted; 4, reversing is started; 5 reversing is finished. The control system comprises a main control layer, a human-machine interaction layer and a nose driving layer which are in communication connection with the main control layer as well as a main control module in the main control layer and an assistant processing module which is in communication connection with the main control module; wherein the assistant processing module is in communication connected with a storage module in the human-machine interaction layer, and the main control module is also in communication connection with a nose module and a machine body module which are arranged in the nose driving layer. The invention has the substantial characteristics that: each module in the control system is configured, reversing back torque is calculated in real time, namely the back torque is adaptively adjusted, the nose is controlled to reverse according to concrete real-time back torque, the phenomenon that reversing time is wasted in back torque with preset parameter is avoided, and reversing efficiency is improved, thus improving knitting efficiency.

Description

Technical field [0001] The present invention relates to a flat knitting machine head reversing control method and its control system, in particular to a flat knitting machine head high-speed reversing control method and its control system, through real-time scanning to calculate the reversing gyration, to solve the problem of gyration with fixed parameters The problem of wasting time exists in the distance, and the commutation efficiency is improved. Background technique [0002] In the case of high speed, the inertia of the nose is one of the main factors affecting the speed of the nose change. The greater the mass, the greater the inertia. Therefore, on the premise of ensuring the performance requirements of the nose triangle system and other accessories, reducing the mass of the nose is an effective way to increase the commutation rate. In the case of a certain quality of the machine head, the rate of reversing of the machine head can be increased through the application...
