[back] Why use automatic cloths? Clothing production is a promising industry, but competition has become more and more heated. How to break out of the market, and preempt the competitors, systematically control the quality, cost, and efficiency of the finished products; These factors have become extremely important.
The use of automatic paving machine can guarantee quality, reduce cost and improve efficiency. Efficiency: the machine won't be tired and won't be in a mood. It can operate at high speed for a long time. The production efficiency is high and the quality is very stable. Cost: manpower is spread cloth need more task person operation, its wage cost is high. Automatic cloth machine only one person operation, one person can complete the spread work. The remaining staff can cope with other processes, saving costs and increasing efficiency. Quality: cutting the spread the cloth before the effect directly affects the quality of the finished product, after cutting found negative influence is beyond repair, and have emerged on the quality of the finished product, this kind of problem in hands spread quite common cloth, using automatic machine shop is the best guarantee to solve the problem of this. Another advantage of using automatic paving machine can greatly improve the image of the production plant. When customers visit the production mode and production equipment before the drop-off, the automatic machine shop is the most reliable and reliable way to ensure quality, cost and efficiency.
To improve competitiveness, how to use equipment can be backward. How do you know the advantages and disadvantages of automatic spreading machine? Machine shop in the clothing industry has existed for many years, but in the past have not been able to record, because before the introduction of computer control technology, the old and traditional control technology has to go to the limit, a lot of problems cannot operation breakthrough, such as feed line and the machine can't accurate synchronization, both downtime cannot be accurate positioning, the problem such as weight and inertia force, are serious affect the performance of spread the cloth. Today has entered the era of science and technology, computer technology application in spread cloth technology has been developed to get incisively and vividly, as breakthrough the limit of the old mechanical control, a new generation of spread machine, no matter in the treatment of highly elastic and soft cloth, or weight 200 kilograms heavy cloth, spread the cloth function also can also achieve perfect state. As long as the careful reference of the various functions of the machine, how many items are actually controlled by the computer, it is easy to distinguish the advantages and disadvantages of the spreading machine. A lot of people think that it's a common misconception that a spreading machine has a light touch screen that is equivalent to computer control. Because the light touch display screen can only be used as a kind of information display and control of the electromechanical switch, so it is not necessary that the machine is controlled by the computer. How to distinguish the degree of computerization of the laying machine, it is not difficult to tell apart from careful comparison. Basically mechanical computer control, first of all need a can 颣 mutual understanding way of communication with people, this is the digital (commonly known as: nc). By this we can easily compare.
The computer control and non-computer control of the various functions of the laying machine:
The positioning control of the walking machine
Computer control: the right and left ends of the stop position (numerical) are computer memory.
Features: the location of the left and right sides of the data display can be seen in the data display.
Advantages: (1) it is very easy to change the stop location. (2) because the computer always knows the location of the laying machine and the location and distance of the stop point, it is absolutely accurate to control the stop position.
(other brands) non-computer control: an electromechanical touch stop device is required on the right and left side of the bed.
Feature: to change the stop position, the stop device needs to be moved to a new location.
Disadvantages: (1) changing the location of the stop is boring. (2) the gap between the sensor and the stop sensor is larger, causing the stop position to be inaccurate. (3) the speed change and inertia force of the paving machine also cause the stop position to be inaccurate. Incorrect location is the cause of waste cloth.
Speed control of the walking machine
Computer control: the movement of the laying machine is controlled by the precision software of the computer.
Feature: change speed simply by displaying data, easily changing the value of walking speed.
Advantages: the cloth machine is heavy and high-speed moving equipment, only the advanced robot control technology, can make the movement of the spreading machine freely, play the perfect spreading function.
(other brands) non-computer control: the moving speed of the laying machine changes only by reducing the power supply to the motor.
Feature: speed adjustment is used to adjust the rotation, and the deceleration buffer needs to be installed on both ends of the bed.
Disadvantages: to change the deceleration buffer before the stop, you need to adjust the distance of the slow track. In addition, the speed and position of the paving machine cannot be controlled accurately by reducing the power supply of the motor.
The cloth machine synchronizes the cloth control
Computer control: use computer precision software to control synchronization.
Feature: to change the speed of the delivery speed, simply change the speed of the feed through the data.
Advantages: due to the machine shop mobile distance, speed, and feed control all of them are performed by the computer, with high-tech CNC motor, the implementation of computer instruction can perfectly, really achieve absolutely accurate synchronized feed, laying the cloth of guarantee perfect effect.
Non - computer control: use of a mechanical gearshift device.
Feature: to change the speed of the delivery speed, it needs to rotate the ring without the speed change.
Faults: the mechanical unchanging speed can only reach approximate synchronization, it can't be accurate. It is easy to be affected by the change of speed, and it is also a kind of wear device. The longer the use time, the less reliable the accuracy.
Control of cutting function of paving machine
Computer control: all functions are computer controlled.
Features: various functions such as cutting or not, cutting length, cutting speed, automatic lifting height, automatic sharpening, etc. These functions can be easily changed through data.
Advantages: the whole cooperation of computer precision software can combine various kinds of laying patterns, so that the work of laying cloth can be more selective.
Non-computer control: mechanical and electrical control.
Feature: function cannot be selected.
Disadvantages: the function cannot be chosen.
In addition, its control mode is more review, the damage rate is higher. All kinds of control modes used in today's bunk machines: (advanced) all-computer control mode: using the central processing unit (CPU). Hundreds of control programs developed by the manufacturers themselves are permanently stored in the CPU.
Advantages:
(1) the control software is permanent storage cannot be rewritten, absolutely is not affected by electrical noise and external magnetoelectric interference, don't need to worry about control software fault disturbance, use with the stability and safety of one of the best.
(2) the control software is developed by the manufacturer of the laying machine, and the manufacturer can update and improve the control software continuously in the light of the needs of the laying machine, so that the effect of the laying cloth will remain the highest standard forever. (other brands) (less) semi-computer control mode: use a programmable controller (PLC) that is available on the market. In response to the programmable controller, the manufacturer of the paving machine can provide the functional scope of the application and apply these functions to the control of the laying machine.
Disadvantages:
(1) control programming writing can be rewritten many times in the storage of electronic components, these electronic components are vulnerable to the power supply noise and external interference, magnetic and to control the programming to make damage to operation, stability and safety are a problem.
(2) the function of the programmable controller to provide standard within a certain range, the mountain of the practical need of machine shop could not only could spread to the design of the machine, to accommodate the function of the programmable controller, often make the effect is not so ideal.
(other brands) (very backward) traditional electromechanical logic control mode: logic circuit with high complexity and high damage rate. This ancient control mode should be operated with a large number of mechanical transmission and mechanical transmission.
Disadvantages: the design review and production cost are high, plus the limit of the technology, it is impossible to achieve precision in the control aspect, the spreading effect is not ideal, the problem is more easily damaged.
