Abstract

The invention discloses a controller for a towel hemming machine. The controller is characterized in that an STM32 control chip is adopted as a core, an open interface and the design of modularization are adopted, meanwhile, the human-computer interaction and the parameter setting are realized through the adoption of a touch screen and serial port communication, the controller has the function of self-checking semaphores, and the functions of program downloading, executing and monitoring can be realized; the controller is divided into a main control part, a sewing part and a label part, wherein the main control part is responsible for the feeding, the cutting, the transportation and the like of towels; the sewing part is responsible for the signal processing of a sewing machine and the synchronization of a stepping motor; the label part completes the cutting and the addition of labels. According to the controller disclosed by the invention, the work is reasonably allocated to the three parts; procedures, such as the feeding, the flanging and the sewing of the towels can be completed, so that the automated production processes from raw materials to finished products of the towels are realized, and the production efficiency is improved.

Description

Towel edge machine controller

Technical field

The invention belongs to light industry and machinery electronic device field, be combine machinery, electromechanical integration equipment that electronics, control technology are integrated.

Background technology

Along with society and the development of science and technology, Sewing machines obtains huge development as clothes secondary industry production equipment, raising sewing quality and efficiency are the targets that Sewing machines industry is constantly pursued, current industrial Sewing machines is to automation and intelligentification future development, automatization level progressively improves, its general principle is the same, the i.e. trimming of Sewing machines, the performance elements such as feeding still adopt former mechanical structure, and controller aspect generally adopts the Control System of Microcomputer such as electronic control system or Programmable Logic Controller, industrial sewing machine is made to realize self-feeding, automatically line is pulled out, the functions such as burn out detection.But China starts late in high performance control system Sewing machines field, technical merit is not high.

Meanwhile current social, the demand of towel grows with each passing day, although China is towel big producing country, is not also that power produced by towel.There is production scale little, designer lacks, the shortcomings such as weak capacity for independent innovation, and the development of China's industrial sewing machine in towel field is quite slow, most towel enterprise still adopts semi-automatic edge machine, and independent intellectual property right is not had in towel production equipment key technology, be merely able to, by the competitive advantage improving oneself of introducing technology, therefore be necessary to carry out the independent research of towel sewing device.For this problem, the present invention proposes a kind of controller based on towel automatic seamer.

Summary of the invention

The object of the invention is to: in conjunction with the mechanical structure of industrial sewing machine and Computer Control Technology and automatic control technology, design a kind of automatic controller for towel edge machine.This controller not only can realize automatic tape edge function, and integrate the functions such as man-machine interaction, optimum configurations, signal self-inspection, download program execution monitoring, and be divided into master control, sewing, label three parts, realize controller moduleization design, complete towel by the Automated condtrol process of raw material to finished product.

The towel automatic seamer controller of the present invention's design take STM32 as main control chip, in conjunction with formations such as host computer, touch-screen, number connect test module, serial communication modular, performance element, indicator lamp, stepper motor, AC servo motor.The performance element such as trimming, take-up, feeding of edge machine adopts former mechanical structure, repeats no more here; The man-machine interaction of controller, optimum configurations; The identification of digitlization fluorescence signal is realized by graphics processing unit, ultraviolet fluorescent lamp, reader for two-dimension code, number comparison decision unit; Digital magnetic safety line Signal analysis is realized by magneto-dependent sensor, number comparison decision unit.

1, main control module

Main control module, as control core, plays " heart " effect in the entire system.

The core component of controller main control module is ARM chip, and its function is given by controller system program

Function, receive and store the performing a programme code and data that PC machine sends, receiving state and the data of on-the-spot input unit by the mode of scanning, and being transmitted, combine, compare, convert, completing the logic control or processor active task that specify in performing a programme.

2, number connect test module

Digital quantity input module mainly completes the input service to outside industrial equipment state digital quantity, the on off state of external industrial equipment is after light-coupled isolation, the process of input signal change-over circuit, enter in parallel input/SOD serial output data register, last controller utilizes serial date transfer mode to read data.

Digital output module mainly completes the control to outside industrial equipment executive component, controller utilizes the serial data way of output to export data, data enter serial input/parallel output data register from controller, after the process of output signal change-over circuit, be converted to the control signal of external equipment executive component.

3, man-machine interface

Man-machine interface selects graphic control panel, mainly realize the setting of edge machine parameter, and by serial communication, parameters is sent to controller, by touch-screen, information should be conveyed to operating personnel when system goes wrong, such as Sewing machines broken string, feeding end is without material etc.

Accompanying drawing explanation

Fig. 1 is the system functional block diagram of this controller;

Fig. 2 is the functional schematic of graphics processing unit.

Detailed description of the invention

Towel automatic seamer controller is electromechanical integrated product, relates to the knowledge in multiple fields such as machinery, electronics, control technology, needs each side to work in coordination.Only the specific embodiment of the present invention is described below.

The raw material of towel automatic seamer is continuous print towel (middle not cutting), raw material is placed on feeding end, now should notice that the matte of towel should along the contrary direction of feeding, such fine hair checkout gear just can accurately detect fine hair, the relevant parameter of tackling towel before powering on is arranged, as the gap of towel length, sewing, the need of tagging.Be provided with rear system just can run, first by take out device, towel is taken out, the determination of its length has been come by equipment for straightening, equipment for straightening is uniform descent before this, when slowly dropping to setting value close to starting during preseting length, towel and raw material are disconnected by cutting part after confirming by towel length, by transport portion, the raw material cut is delivered to folded part again, required label can be added in the raw material folded while folding, by transport portion, the raw material folded is delivered to sewn portion equally, sewn portion is completed by Sewing machines and stepping motor synchronous, the functions such as the distance of the sewing gap set before realizing edge machine work by programming and time seam, such finished product towel just out.
