The process of prepress and printing has developed rapidly and continues. The rhythm of process innovation continues to accelerate. The printing equipment of yesterday was continuously replaced by more advanced equipment with better quality and higher productivity. Can process and cut 15000 copies or more of prints per hour.
Increasing print productivity means that more material needs to be handled and handled. Polar has kept pace with the development from the very beginning - from the constant modernization of the paper cutter to the latest integrated computer controlled cutting machine. In addition, Polar also recommended a smooth production process, using a material processing peripheral system.
In 2000, Polar launched a new set of products. They are both complementary to existing equipment and also serve large-scale label production including complementary products that improve the performance of high-profile production equipment.
Polar's products include the following equipment;
Cutters, from the smallest Polar 66 t to 176, ie from 66 cm to 176 cm in width.
Peripheral equipment for material handling Paper lifter Paper roll elevator Paper picking Machine equipment Cushioning stacking equipment Automatic loading and unloading of paper Loading equipment Transportation system Complete paper cutting system Complete paper cutting system consisting of the above components Trademark labeling systems include on-line conveyors, die-cuters, die cutting, and tying equipment. Pile Turners palletizing equipment Stack turning machines Generally speaking, cutting is a simple work process, but with the great progress of industrialization, In the field of paper processing in the printing industry, the traditional process has also undergone tremendous changes. Printing opportunities and bookbinding machines have gone through several generations of stacking from tape-controlled cutters to the latest microcomputer-controlled cutting systems. Research and development have resulted in new cutters and cutting system equipment with high cutting accuracy, strong cutting capacity and high throughput. In just a few years, there have been cutting machines with color display, full image operation guidance, visual processing and computer-assisted cutting of external programming and editing of production data. The purpose of all these improvements is always to make the cutting process more economical. The result is higher production per process and shorter lead times. Here are some important aspects of the cutting process.
1, material preparation 2, cutting process 3, loading paper and unloading paper 4, further processing requirements 5, requirements for employees.
Explanation:
1, cutting material preparation -
Including paper inspection or quality control, including quantity quantification, and alignment of paper (centering - ie, regular gripping process alignment).
2, cutting process process - including the actual cutting operation,
The method of programming operation can be done manually, automatically, or it can also be done at other tables away from cutting.
In addition, it also includes automatic programming of the machine room, which can be supplemented with a help plan for material handling on the machine cutter table or paper cutter.
The necessary choice of machine cutters depends on the requirements of the specific cutting job process. It is becoming more and more important to reduce the waste of cutting under the conditions of industrialized high-scale production.
3, Cutter loading and unloading capacity.
The process can be manual or automated. Depending on the volume of the material, the paper can be loaded on the table through the front or back side of the cutter cutter. Depending on the required work flow, paper can be discharged on the left or right side of the machine cutter.
4. Requirements for further processing Cutting paper is not always the final stage. Often, materials are transported to another place for further processing. The cutter can therefore be linked to the next station to shorten the entire production cycle.
5. Requirement for Employees Choosing who works next to the paper cutter is very important for productivity and efficiency. Many people cannot ensure maximum production. The important thing is how to arrange a person who has knowledge and ability, and is equipped with a combination of appropriate equipment and suitable equipment.
After stressing these cutting processes, it is easy to understand the following prerequisites for efficient cutting;
1, high-performance paper cutter 2, paper cutter orientation oriented 3, high-quality cutting tools (knife and good grinding knife device).
4, suitable processing equipment (peripheral equipment)
5, Good preparation for cutting material 6. Arrange qualified personnel in material handling positions.
Due to the special structure of the printing industry, the size, production line, and printing process of the printing company are all different and other characteristics. The paper cutting machine manufacturers must provide various grades of paper cutters with different levels of automation. . There are two Polar cutters with very special electronic controls available in two models, available in 7 sizes. They all use a dedicated electronic control system to meet the needs of various art and graphic printing industries.
The corresponding cutting length of the Polar cutter is 66, 78, 92, 115, 137, 155 or or 176 cm.
The model of the paper cutting machine is Polar E and Polar ED.
The Polar E-Eltromat is the basic model for general cutting operations. It is programmable, has 128KB of storage capacity, and is approximately equivalent to approximately 12000 cutting positions. This type of machine is equipped with automatic programming and the most important function of arranging the automatic working sequence. This type of machine has the most important function of automatic programming and automatic execution of the working program. It also has a simple text input function that can record the customer's name and the user's description of their own name and process job description.
The Polar ED-Eltromat Dialog is the most exclusive of the series and represents the future of cutting technology. It can meet the challenging cutting process and programming requirements. The Modes ED model is a paper cutter specially designed for professional and special designed printers. It can eliminate all possible problems and work without difficulty. It has a wider range of options for a variety of special applications. It is like a text keyboard with an integrated integrated circuit that allows the operator to enter job descriptions and other process specifications and related production information. At the same time, the ED was designed to be designed as a control center for a computer-controlled cutting system.
All modern Polar cutter cutters, from the most basic standard models to the highest models, have the following outstanding technical and operating performance:
easy to use:
The control panel is placed so that it is convenient for the operator to operate. The flat key input system is completely dustproof and splash proof.
Even difficult programs can be quickly recorded and recorded because the arrangement of the controls is logical and the symbols are easy to understand.
All Polar cutter cutters can speak in a variety of languages, including Chinese, and talk to machine cutters. They can display all cutting programs with various information such as command data, material handling information, clamping pressure pressure, knife angle, operation mode adopted according to the purpose of use, and usage hints.
The modern cutter cutter contains the following technical features:
* High resolution 10. The 4" LCD display signal quality allows the process to be visualized effectively.
By means of a module-by-block programming system or an external Polar Compucut software sb device, the page layout on the printed sheet to be cut will be automatically generated on the paper cutter by the arrangement of the image on paper.
* The high-accuracy measurement and positioning system consists of a precise linear guidance system for backgauge used by a direct pulse generator, frequency-controlled drive motor, high-precision axis with universal ball bearings, and a backstop.
The pulse generator is directly and firmly connected to the rotating shaft. This element transmits the measurement data to the LCD liquid crystal display diode as an electrical signal. The cutting position is displayed with an accuracy of 1/100 mm.
Rear-gear drive: The highest reversing speed of 30 cm/s is achieved by a frequency-controlled, adjustable drive motor with automatic braking and acceleration/deceleration.
The pressure of the paper clamping clamp indicates that at the working height, any type of cutting material can be rapidly and steplessly adjusted hydraulically. This function uses a hydraulic continuously variable transmission. At normal working height, the pressure level of different kinds of paper can be quickly adjusted according to the precise pressure level. Polar's platen clamping pressure range, the minimum pressure is extremely low, in order to properly handle extremely fragile paper. For example, the minimum pressure of the Polar 115 can be very flexible from 150 kg to a maximum pressure of 4500 kg.
Knife drive: The drive system of the knife is designed to be solid, secure and requires little maintenance. The worm gear runs in the tank.
Hydraulic clutch: It transmits all the drive force to the knife. In fact, this clutch is basically not worn.
Self-diagnosis system:
The continuous monitoring of all functions of the machine paper cutter, if there are any errors or abnormalities, there will be an immediate signal display, clearly displayed in words, so that, sometimes even through a telephone, it is possible to eliminate the malfunction as soon as possible.
In addition to various standard features, Polar offers many ways to solve specific cutting applications.
The Polar Autotrim is the world's first high-speed paper cutter that automatically eliminates waste and automatically collects small cutting products on the supporting worktable support board. Autorim is the most efficient advancement in high-speed cutters since the computer programmed control of the cutting machine.
The advantage is that the operator does not need to manually remove the transportation waste while cutting, and when the waste is cut out, the desktop can remove the waste by opening the front table of the machine paper cutter. This feature is optional to increase production by up to 30%.
Autotrim has the following features:
1, there is a certain starting position.
2, in the cutting cycle: rely on the program to open the front table desktop, scraper moves up, waste scraping into the waste box or sucked into the suction duct.
3, The back gauge pushes the material to be cut to the front workbench desktop or auxiliary worktable support board.
4. The cutting machine is ready for the next cut, and the material has been placed on the supporting workbench support board.
Swing back gauge, inclined back gauge and Fixomat
There are many special options available to support the operator for high-precision cutting. They can align the printed image translation with the cutting line, compensate for tangible or less cuts, or simulate the imitation of the paper on the registration point marked on the printing press and the registration machine.
Tooth Claw Loading System This optional accessory is attached to the rear table of the machine paper cutter. It is from the paper cutter, the paper loading desk, the air pressure platen or On other equipment, multiple stacks of paper are lifted and placed on the rear table of the rear table of the paper cutter, provided that a retractable side gauge.
