Key Words: Shoe-Making And Leather Making Technology: Intelligent Automation

This year, the world's most authoritative fashion and technology, leather and leather products industry technology event, SIMAC&TANNINGTECH2013, was successfully held on October 8~10 at the Bologna International Exhibition Center in Italy.

In the same period, the LINEAPELLE Autumn Fair was also held in the same hall.

According to the organizers, the number of spectators at this exhibition was flat last year, but the number of high-quality spectators increased.

Gathered from 22 countries, 248 footwear, leather and leather technology and mechanical equipment and other enterprises, the official exhibition group from Eastern Europe (Bulgaria, Russia and Ukraine, etc.), Europe, North Africa and Sahara Africa (Algeria, Mali, Morocco, Tunisia), South America (Chile, Columbia, Ecuador and Paraguay), the Middle East (Iran) and Asia (Bangladesh, India, Indonesia, Mongolia and Pakistan).

LINEAPELLE released the trend of autumn and winter in 2014.

Official statistics show that every year, the world's leading technology solutions not only guarantee the quality of products, but also ensure that the whole production stage is compatible with the social environment and promote social harmony.

This year's exhibition is still popular. Footwear and leather goods and machinery manufacturers have launched the latest products and technologies. Some of them are not imaginative innovation and increasingly extreme, advanced material applications, creating new trends.

Key word: Intelligence

1.

This year, CAD has brought together three leading international software companies: Italy Shoemaster, British Delcam and Portugal Mind, all showing 2014 shoe design software, which has achieved many intelligent functions in the past.

Taking DelcamShoemaker2014 as an example, the pitional technology from manual imitation to self development is added, which combines traditional manual tracing to the process of computer 3D edition.

On the "rendering" function of three-dimensional rendering, three have been accumulated for many years. On this basis, it can be extended from design to sales: DelcamShoemaker2014 completes the 3D part of shoes, automatically decomposes shoe parts with animation, and consumers can get 360.

Watch the components of shoe parts, and then combine them with animation to stimulate face-to-face sales as well as online orders. Consumers can make personalized choices on the Internet.

There are also some intelligent implementations, such as making last: having a last and similar hand on hand.

When developing data, we need to develop a new shoe last. The software can realize the function of automatic mobile and automatic combination, automatically change the color and line, reduce manual intervention, and achieve faster, better and more accurate purpose.

As everyone knows

There are flaws: Blood tendons, dark wounds, skin scars, lines...

Traditional practices rely on handcraftsmen's experience to identify them. As a result, the inspection of leather masters has increased because of their qualifications.

CAMOGA, a famous shoe maker in Italy, brings a surprise to the industry: self developed leather scanning technology.

The defects of natural leather can be identified or even classified, and the grade of utilization can be automatically identified and calculated by software, so that the utilization ratio of natural leather and the protection of beneficial animal resources can be greatly improved.

An intelligent recognition of leather material is actually classifying all kinds of defects and customizing A, B, C and D.

The process of grading, then set up a grade (the best part of leather) is used for important parts such as shoes, B class (though defective), but it can be used, commonly known as "eating materials". C and D levels may not be utilized, and the ratio of all grades to the whole leather material can also be calculated by software intelligence.

3, intelligent typesetting

Fully automatic leather typesetting has always been a worldwide technological tackling problem in the field of numerical control leather layout and cutting.

Several brands have upgraded technology and products every year.

However, the leading technology of this exhibition is...

A black horse from Asia -- Emma numerical control, Dongguan, China.

Since the launch of automatic typesetting software in 2008, based on the practical application of customer factories, after 6 years of continuous R & D and upgrading, the 6 edition of the iwin AI cloud multi-core cloud intelligent typesetting system was launched in September 2013.

According to the introduction, the operation speed can be increased by 2~4 times compared with the previous version (1.0~5.0). Compared with manual processing, it can save time and enhance production efficiency greatly. It also saves more manual labor and reduces labor intensity for manual workers, thereby improving work efficiency. It is also exhibited at China International Leather Exhibition and the 2013 largest sewing equipment exhibition in the world.

This year is Emma's debut in SIMAC&TANNINGTECH.

4. Intelligent operation

And intelligent operation applications, especially one of the Italy clippers giant CERIM, the latest "CALIBRATORE" system is the most advanced.

"CALIBRATORE" is a visual system that can be configured on the CERIM production support machine to ensure that any type of production meets the required quality standards.

It is composed of a camera and a display screen, which can be connected with the electronic control system of the machine, and help the operator to correctly locate the upper part of the shoe in a simple and direct way, whether it is a right foot or a left foot.

The camera is vertically aligned on the shoe (upper upper shoe) for viewing from above.

At the setup stage, when all the parameters of the machining model are memorizing by machine, the upper (for example, the right foot) used for reference is placed on the machine: the inspection center locate, adjust the clamping jaw and pull in the right way.

With these completed, a picture will be taken and combined with each processing program: the software will automatically process the image so that it can be applied to the left foot (according to the initial step, also the right foot).

The image is saved to create an electronic file that can be copied for other CERIM machines: always the model mentioned above.

In the production process, when the operator extracts the production process of the shoes being processed, a picture of the reference shoe will appear on the screen.

At this time, the camera starts to start: through a special software, the images of shoes at the stage of help are covered by photos stored.

The covered image is pparent, enabling the operator to perform all necessary adjustments in a simple and quick manner, so that the reference image and the processed shoe can achieve the perfect alignment effect.

If the result is satisfactory, the parameters can be saved for the production of corresponding batches.

In addition, the machines equipped with the "CALIBRATORE" system also ensure the traditional production capacity and can also be operated by non professionals.

5, intelligent pmission

ANZANI and VOLONTE, which represent the highest level of footwear manufacturing industry, have brought the world's most advanced "intelligent pport technology": in the pipeline pfer process, it can clearly distinguish small quantities of orders, distinguish all parts of shoes, achieve three-dimensional pmission between different jobs in the sewing process, and reduce excessive manual intervention.

The realization of more intelligent functions has made the traditional flat production line of Asian factories far behind.

6, intelligent peeling

Therefore, it can be speculated that the future shoe making intelligent technology will become modularized and smaller.

For example, the newest peeling machine, based on the experience of thinning, develops a handwritten input method similar to electronic products, often enters a word, and it automatically pops up a word and word related to it. The principle of intelligent peeling machine is also the same.

Although intelligent implementation is a relatively long process, every step is the crystallization of human intelligence. The purpose is to reduce the artificial experience value, speed up the process and enhance efficiency.

Keywords two: automatic

With the advancement of industrialization, resources are becoming less and less, and automation technology is applied more and more widely.

The technology of shoemaking and leather automation has always been a new meal for SIMAC&TANNINGTECH.

1. Automatic cutting.

The world's five largest leather CNC leather cutting machine brands COMELZ, TESEO, ATOM, EliTRON, EMMA (Dongguan Emma) are present to show the most complete category, the most diverse technology combination and the richest hardware and software category.

All five have brought the quicker and more efficient streamline pmission line, automatic cutting automatic pmission technology, single head, double head, three head and multi head cutting technology for production line layout and receiving.

According to reports, Emma from Dongguan, Asia, is also developing three head, four head and six head cutting technology, in order to help the traditional factory speed up and increase production capacity, liberate manual labor and experience value.

2. Automatic sewing.

This year, the field of automatic sewing has also seen the rapid development of technology for all audiences.

In addition to the continuation of traditional computer XY axis pmission,

It can further achieve the 360 degree rotation and ensure that the stitches follow the original law, and the functions of the shoemaking industry, such as single needle, double needle and thick line, are innovated. In the application process, a superposition technology has been created. In the past, the sewing process of cars is a whole piece of stitching, which is applied to the shoemaking field. According to the specific shape of shoes, it needs to realize multi-storey stairs seams, or even three layers of seams, and the maximum width of the processing area is up to 100 x 100cm, and the price is very high, which is about 8~10 euro / Taiwan.

3. Pliers machine automatic glue.

The traditional upper is glued, that is, simply brush the glue by hand.

This year's automatic + intelligent combination technology has brought more new expectations to the industry.

The biggest highlight of this technology is that the glue can be automatically adjusted, and the glue thickness and glue position can be controlled according to the different intelligence of the last type.

It can reduce the direct contact between hand and glue, and also save glue material, and the effect is uniform and beautiful.

4. Automatic pmission

The automatic pmission technology introduced here needs to be differentiated from concepts: first, pipelined automatic pmission, and second automatic pmission of mechanical arms.

This is mainly recommended for automatic arm pmission: from A station shift to B station, no manpower required.

Some functions are directly designed in the machine, while others are solved by mechanical arm alone.

For example, the shaping process, the jig of the pliers, the shoe last to be conveyed to the conveyor setting machine. After setting, the other clamp will clip the shoe last to the freezing link, and the whole process will completely replace the manual.

5. Automatic grinding (edge / sand bottom).
