CN103966828A - Automatic control method for edge cutting of cutting machine - Google Patents

Abstract

The invention discloses an automatic control method for edge cutting of a cutting machine. A frequency changer is adopted to control a three-phase asynchronous motor, so as to drive a main shaft; the main shaft is linked with an edge cutting device through a synchronous belt; a 1-15 speed reducer is mounted inside the three-phase asynchronous motor; an encoder is mounted at the other end of the speed reducer output shaft; a limit sensor is mounted at the left end and the right end of the edge cutting device respectively; the extreme position of the limit sensor at the left end and at the right end serves as a zero position; the width of automatic edge cutting cloth is 2500 mm. According to the invention, the encoder is utilized to count and automatically position the cutter with an error within 2 mm; the edge cutting is convenient and rapid; the operation is simple; the positioning is accurate; the adjustment time is greatly saved and the production is increased.

Description

Autocontrol method is cut on guillotine limit

Technical field

The invention belongs to house and spin mechanical field, particularly autocontrol method is cut on a kind of guillotine limit.

Background technology

It is all the position of manual adjustments cutting knife that part is cut on existing guillotine limit, after completing, normally produces.So, the size of cloth cutting, error strengthens, and affects the quality of product, in addition, has also caused production efficiency low, has wasted manually, causes production cost to increase.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of guillotine limit of fast, precisely, greatly saving the adjusting time and cuts autocontrol method.

In order to solve the problems of the technologies described above, the technical solution used in the present invention is:

1. an autocontrol method is cut on guillotine limit, it is characterized in that: the concrete steps that autocontrol method is cut on this guillotine limit are as follows:

S1 sets limit and cuts the pulse number that 1CM produces;

S2 manually debug limit cut move left and right whether correct;

S3 sets the width of producing cloth;

S4 selects to cut width;

If the width that need to cut is 2500MM, operating procedure is as follows so:

1) left side is cut and is made zero;

2) the right is cut and is made zero, and it is that cut on the limit of 2500MM that limit cutting apparatus can complete width automatically;

If the width that need to cut is for being less than 2500MM, operating procedure is as follows so:

1) regulate sensor localization position;

2) limit cutting apparatus moves fast;

3) approaching desired location runs slowly;

4) arrive formulation back, position cutting apparatus and stop, manually cut on limit.

The present invention uses encoder to count, automatically to cutting knife location and error within 2MM, convenient, fast, simple to operate, accurate positioning, greatly saved the adjusting time, improved output.

Detailed description of the invention

Below in conjunction with detailed description of the invention, the present invention is described in further detail:

Autocontrol method is cut on a kind of guillotine limit, utilize Frequency Converter Control threephase asynchronous to drive spindle, this main shaft is by the Timing Belt limit cutting apparatus that links, described threephase asynchronous machine is equipped with the reductor of 1:15, the speed reducer output shaft other end is installed an encoder, the left and right end of limit cutting apparatus is equipped with respectively a limit sensors, and wherein the spacing extreme position in left and right is zero-bit, and the width of the cloth of cutting is 2500MM;

The concrete steps that autocontrol method is cut on this guillotine limit are as follows:

S1 sets limit and cuts the pulse number that 1CM produces;

S2 manually debug limit cut move left and right whether correct;

S3 sets the width of producing cloth;

S4 selects to cut width;

If the width that need to cut is 2500MM, operating procedure is as follows so:

1) left side is cut and is made zero;

2) the right is cut and is made zero, and it is that cut on the limit of 2500MM that limit cutting apparatus can complete width automatically;

If the width that need to cut is for being less than 2500MM, operating procedure is as follows so:

1) regulate sensor localization position;

2) limit cutting apparatus moves fast;

3) approaching desired location runs slowly;

4) arrive formulation back, position cutting apparatus and stop, manually cut on limit.

The present invention uses encoder to count, has replaced manual adjustments cutting knife, convenient, fast, simple to operate, accurate positioning, has greatly saved the adjusting time, has improved output.

In sum, content of the present invention is not limited in the above-described embodiments, and those skilled in the art can propose other embodiment easily according to guiding theory of the present invention, and these embodiments all comprise within the scope of the present invention.
