Abstract

The invention provides a method for automatically determining the cutting region of a cutting table, and belongs to the technical field of cutting tables. The method solves the problem that in the prior art, in determination of fabric cutting, manual measurement is needed or cloth needs to be ceaselessly replaced manually to adapt to cutting. The method for automatically determining the cutting region of the cutting table comprises the following steps that first, cloth is placed; second, locating points of the cutting region are set, and a starting point is determined; third, the cutting region is determined; fourth, the cutting region is successfully determined, wherein after a cutting head is controlled by a control computer to pass all the locating points in sequence, the piece of cloth can be cut. The method has the advantages that whether the cloth can be cut into a graph or not can be judged, preprocessing for cutting is achieved, the problems that in the cutting process, cloth is in shortage or is scrapped are avoided, the usability judgment process of the cloth is comprehensive and careful, the determination of the position of the cutting region is standard and accurate, and it is guaranteed that a subsequent cutting process is smooth and free of deviation.

Description

The clipping region automatic determination method of cutting

Technical field

The invention belongs to cutting technical field, refer in particular to a kind of clipping region automatic determination method of cutting.

Background technology

In traditional cutting apparatus field, clipping region is FX, artificially cloth is moved to after in clipping region, in FX, cutting is carried out according to typesetting figure, and because the edge irregularity of out-of-flatness and cloth itself put by cloth, therefore and the present invention is the series of problems that the artificial moving cloth of solution brings operating efficiency can be caused to reduce and cannot effectively the utilizing of cloth, and can worker efficiency be improved.

Summary of the invention

The object of this invention is to provide a kind of clipping region automatic determination method of cutting, is adapt to traditional moving cloth the change that clipping region mode fixed by machine, effectively can solve artificial moving cloth and cause the low and cloth of efficiency to put the problem of inclination.

The object of the present invention is achieved like this:

The clipping region automatic determination method of cutting, is characterized in that: comprise the steps:

A, placement cloth: cloth is sent on cutting platform;

B, arrange clipping region anchor point and determine initial point: the multiple anchor points controlling computer is arranged cutting figure in cutting, sanction head to the first anchor point of mobile cutting, and guarantee that the color-changing lamp cut out on head is beaten on cloth;

The determination of c, clipping region: control computer and to calculate on first anchor point to the route of next anchor point and cutting the distance of first anchor point to next anchor point according to the cutting feature size arranged in b step, control conputer controlled sanction head to move along route, whether the color-changing lamp that monitoring is cut out on head is beaten on cloth always, is divided into following situation:

If cut out head in step c along in route moving process, color-changing lamp have left cloth, controls conputer controlled sanction head and returns first anchor point, then reset multiple anchor point of cutting figure at control computer or point out this cloth to use;

If cutting out head in step c is moving in next anchor point process, color-changing lamp is beaten on cloth always, after sanction head arrives anchor point, control computer calculates this anchor point on this anchor point to the route and cutting of next anchor point according to the cutting feature size arranged in b step and, to the distance of next anchor point, controls the continuation of sanction head mobile;

D, clipping region are determined successfully: when control conputer controlled cuts out head successively through all anchor points, then this block cloth can carry out cutting.

The present invention gives prominence to compared to existing technology and useful technique effect is:

1, the present invention carries out location simulation on actual cloth to wanted cutting feature size scope, thus can judge whether cloth can be used for cutting this kind of figure, achieves the preliminary treatment of cutting, avoids producing the problems such as cloth lacks, cloth is scrapped in cutting process.

2, the present invention is after judging whether cloth can be used for cutting this kind of figure, can change cutting figure according to judged result or change the concrete distribution of anchor point, judge that the availability process of cloth is comprehensive, carefully.

3, the present invention installs color-changing lamp on sanction head, and the position of clipping region settles the standard, accurately, ensures the follow-up smooth zero deflection of cutting process.

4, the present invention substantially avoided moved by hand cloth, and improves operating efficiency by the mode of constantly locating, and then improves production efficiency.

Accompanying drawing explanation

Fig. 1 is location of the present invention schematic diagram.

Detailed description of the invention

Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described, see Fig. 1:

The clipping region automatic determination method of cutting, comprises the steps:

A, placement cloth: cloth is sent on cutting platform;

The determination of c, clipping region: control computer and to calculate on first anchor point to the route of next anchor point and cutting this anchor point to the distance of next anchor point according to the cutting feature size arranged in b step, control conputer controlled sanction head to move along route, whether the color-changing lamp that monitoring is cut out on head is beaten on cloth always, is divided into following situation:

If cut out head in step c along in route moving process, color-changing lamp have left cloth, controls conputer controlled sanction head and returns first anchor point, control computer and reset multiple anchor point of cutting figure or point out this cloth to use;

Illustrated by Fig. 1: be provided with 4 anchor points in Fig. 1 altogether, anchor point 1 is first anchor point, lights color-changing lamp and mobile head of cutting out makes the bright spot of color-changing lamp beat on cloth on first anchor point 1 at control conputer controlled;

After first anchor point 1, control the X-direction length m that computer calculates current window typesetting figure, sending instruction allows sanction head arrive second anchor point 2 to X-direction movable length m, determine that cut out head color-changing lamp bright spot in movement beats on cloth always, if no, then first anchor point 1 can be returned reorientate;

If after sanction head successfully moves to second anchor point 2, determine that rear controller calculates current window typesetting figure Y-direction length n, sending instruction allows sanction head arrive the 3rd anchor point 3 to Y-direction movable length n, determine that cut out head color-changing lamp bright spot in movement beats on cloth always, if no, then first anchor point 1 can be turned back to reorientate;

According to said process principle, if after sanction head successfully moves to the 3rd anchor point 3, cut out head to continue to move to the 4th anchor point 4, determine that cut out head color-changing lamp bright spot in movement beats on cloth always, if no, then can turn back to first anchor point 1 and reorientate, successfully move on the 4th anchor point 4 if cut out head, then the deterministic process of clipping region is complete, and this cloth can carry out cutting.

For more complicated figure location, only need be preset with anchor point in control computer, then automatically determine clipping region.

Above-described embodiment is only preferred embodiment of the present invention, not limits the scope of the invention according to this, therefore: all equivalence changes done according to structure of the present invention, shape, principle, all should be covered by within protection scope of the present invention.

Claims
