Embodiment Construction

[0014] In order to make the technical solution, technical purpose and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings.

[0015] The network system structure of the present invention is as figure 1 As shown, the three leather cutting machines are networked through CAN bus technology, and their working status is uploaded to the dedicated gateway in real time. The dedicated gateway converts the protocol and then transmits it to the industrial Ethernet. Finally, the networked PC workstation and Control server for real-time reads. At the same time, because it is necessary to design the layout strategy and plan the sample cutting sequence for the processed leather fabrics, an industrial camera is installed at the gantry in front of each CNC machine tool in the system to quickly take pictures of the leather fabrics in the conveyor belt, and It is transmitted to the dedicated gateway thro...

Abstract

The present invention proposes a leather optimization nesting and multi-machine coordinated cutting technology based on the industrial Internet. The heterogeneous network fusion technology of fieldbus technology and Ethernet / IP industrial Ethernet is used to realize real-time monitoring and operation of multiple cutting machines. A high-efficiency layout algorithm for two-dimensional irregular sample layout is proposed to realize optimal layout of leather. At the same time, combined with the real-time performance of communication network and multi-machine coordinated cutting strategy, fast pipeline operation of leather cutting and low leather waste rate are realized. Compared with the traditional leather cutting technology, this technology can achieve many advantages such as high efficiency, low waste rate, saving labor costs, and reducing energy consumption.

Description

technical field [0001] The invention relates to the technical field of using a cutting machine to produce clothing fabrics such as leather products, in particular to an industrial Internet-based leather optimization layout and multi-machine coordinated cutting technology. Background technique [0002] The cutting machine is a common equipment in the production process of garment fabrics. Its working process includes: the roller drives the cloth to be fed from the entrance, and according to the layout rules, it is cut by the ax knife or movable blade inside the machine. At present, most enterprises use manual operations such as manual layout and manual cutting for extensive production in actual production, which has the disadvantages of low automation, high labor costs, low material utilization and low production efficiency, which also seriously affects the quality of clothing products. quality. With the development of computer technology and the introduction of layout algor...
