Embodiment 1

[0028] A method of fabric cutting, such as figure 1 As shown, the following steps are included to achieve the cutting of trapezoidal pieces of the same height:

[0029] 1.1 The first trapezoidal pieces 1 with the same height to be cut are distributed and designed in the form of lateral complementation to minimize the range of waste 8, and the distribution design results are imported into the cutting machine control system;

[0030] 1.2 The control system divides the distribution design into sections, in which each section can be completely covered by the cutting range of the cutting machine during the cutting process, and ensures that there is only one row of cut pieces in each section in the direction of fabric conveying. This implementation In the example, the width of the trapezoidal first piece 1 is equal to the width of the cloth, so only one piece is arranged in each column;

[0031] 1.3 Determine the positioning point 7 of the above-mentioned first cut piece 1. The pos...

Embodiment 2

[0037] A fabric cutting method, which is used to realize the cutting of various pieces of constant length but different widths, wherein the width of each piece is smaller than the width of the fabric to be cut, comprising the following steps:

[0038] 1.1 Distribute and design various pieces of constant length but different widths in a complementary form. The design method is to set the length direction of the pieces to be consistent with the length direction of the fabric, and arrange them in sequence along the width direction of the fabric. Try to fit as much as possible to minimize the range of waste 8, and import the distribution design results into the cutting machine control system;

[0039] 1.2 The control system divides the distributed design into segments, such as figure 2 As shown, each section can be completely covered by the cutting range of the cutting machine during the cutting process, and it is ensured that there is only one row of cutting pieces in each secti...

Embodiment 3

[0045] A fabric cutting method, which is used to realize the cutting of each cut piece that is different in length and width but similar in length and whose shape is approximately rectangular, wherein the width of each cut piece is smaller than the width of the fabric to be cut, including The following steps:

[0046] 1.1 Distribute and design the pieces with different lengths and widths but similar lengths and their shapes are similar to rectangles. The design method is to set the length direction of the pieces to be consistent with the length direction of the fabric, and sequentially along the width direction of the fabric. Arrange to form several columns, reduce the range of waste 8 to a minimum by fitting as much as possible, and import the distribution design results into the cutting machine control system;

[0047] 1.2 The control system divides the distribution design into sections, in which each section can be completely covered by the cutting range of the cutting mach...

Abstract

The invention belongs to the field of complex fiber fabric processing and particularly relates to a cloth cutting method for complex fiber fabrics. The method specifically comprises the steps that distribution design is conducted on multiple shapes of pieces to be cut in a complementary way, distribution design results are imported into a cutting machine control system; the control system segmentsthe distribution design, wherein each segment can be completely covered by the cutting range of a cutting machine in the cutting process, and it is ensured that only one row of pieces exists in eachsegment in the fabric conveying direction; positioning points of the segments are determined and need to coincide with the central line of the cutting range of the cutting machine; the control systemcontrols a device to operate and achieves fabric positioning in the conveying process in the mode that the positioning points coincide with the central line, and cutting is performed by using the distribution design of each segment as a motion trail after positioning is completed. By adopting the fabric cutting and fetching method, automatic fabric cutting and taking can be achieved, the working efficiency is effectively improved, and the labor cost is reduced.

Description

technical field [0001] The invention belongs to the field of composite fiber fabric processing, and in particular relates to a method for fabric cutting and cloth taking of composite fiber fabrics. Background technique [0002] Composite material is a new type of material that is composed of organic polymers, inorganic non-metallic or metal and other different materials through a composite process. It does not have the performance, and it has been widely used in the aerospace and automotive fields. The composite fiber fabric can be formed into the desired shape of the structural part by hot pressing, and before the hot pressing, the size and thickness of the final structural part can be met by cutting and stacking the composite fiber fabric. [0003] At present, the process of cutting control, picking and stacking multi-layer composite fiber fabrics of various shapes is mostly realized by manual methods. Although the above methods can ensure the effectiveness of cutting, th...
