As a result of some new changes in the product structure of the printing industry, some new features and requirements have emerged that also affect post-press binding. If the number of printed products continues to increase, but the number of products decreases, the focus is not limited to further improvement in the selection of the configuration of binding machines. Instead, the focus is to adapt to the actual situation of the company (geographical position, site size, staff structure, etc.). Product positioning, etc.) to determine the use of different equipment, so that the binding equipment configuration with greater adaptability, in order to achieve the maximum benefits.
Second, the placement of equipment
Before the binding machine is installed, all preparations must be done carefully, including familiarizing with the technical data, selecting the location, preparing the foundation, and making the installation plan.
When configuring the equipment, it is necessary to plan the placement of the equipment. To prevent the arbitrariness of the equipment installation location, it is also necessary to oppose the wrong practice of where to go when there is free space. It is necessary to scientifically follow how to make raw materials, semi-finished products and finished products flow the shortest distance, make the main logistics distance and location in the production process the most reasonable, and it is the key to production logistics management. "Binding is the center", this point should be fully considered and demonstrated during the entire printing process design. The shorter the logistics distance in the process of paper feeding, paper storage, paper preparation, printing and bookbinding, the better. For example, adding an independent post-press processing equipment near a quick digital printing device is to meet the requirements of short-run and fast bookbinding. The placement of the equipment must follow the principle that the binding machine, finished product store, and finished product shipping table must be connected in a line to ensure that the bound finished product is directly stored and shipped. The rational layout and placement of equipment should comply with the above principles and be developed around this process. The machinery and equipment should be placed on a firm foundation as a guarantee. For machines placed on the upper floors, scientific calculations and arguments should be performed (if the three-side cutter is vibrating, it should be placed on the main beam area with high tolerance. ) If the bearing capacity is not up to standard, measures such as reinforcement should be taken to prevent deformation and sinking of the foundation. In addition, the machine should be placed in a well-ventilated (for heat dissipation and drying), adequate lighting (easy to observe the machine status and check books), small footprint and convenient operator (saving places, smooth access, improve efficiency), and is conducive to Turnover and stacking (convenient for the next section), the site to be stable (to prevent settlement, vibration affect the accuracy of the machine), to save time, effort, economy, and reasonable.
Third, equipment maintenance
The key to whether or not a bookbinding machine can maintain its normal production performance is whether it can extend the stable working period of the machine. Due to the different environments in which the machines are used, the temperature, humidity, dust level of the working environment and the level of user's skills all contribute to the wear of the mechanical components in operation to a certain extent, and the wear of the various components is the fault of the machine. The most direct reason. High-quality management should keep the equipment in the best condition during the production process. If the staple equipment is not properly maintained, not only will there be a lot of downtime failures, but also the accuracy of the product, as well as the production capacity of the equipment. In fact, the problem of equipment maintenance is also a matter of corporate culture. If the operator only determines whether the equipment is faulty by judging the finished product during the operation of the equipment, in this context, the employee will develop a bad habit that does not perform related maintenance or maintenance of the equipment. If we are concerned about quality issues in our corporate culture, this situation will be avoided.
The maintenance of the equipment includes the cleaning of the machine, the lubrication of the machine, and the daily maintenance of the machine. The cleanliness of machines is something that most companies can do, and it's clear day. The lubrication of the machine is not a problem, especially the application of the automatic lubrication system, which provides a reliable guarantee for the lubrication of the machine. However, for the daily maintenance of the machine, many operators are not very clear. From the perspective of machine maintenance, routine maintenance has the greatest impact on product quality. After a certain period of time, the mechanical components will wear to a certain degree, such as the chain, sprockets, cams, etc., which will affect the accuracy of the transmission. These parts should be regularly checked, maintained and adjusted and compensated to maintain the transmission accuracy. Replacing wear parts and updating consumable parts is critical and it will have a direct impact on product quality. Such as flat pressure plate, milling back knives, slotting knives, three-side knife brake pads, cutting knives, chutes, slide ball and other wear parts are easy to wear.
Like suction heads, conveyor belts, blocking bars, and cutting blades are all consumables. The operator should regularly replace the wearing parts and consumables according to the usage time and records, so as to avoid unfavorable operation caused by mechanical wear, ensure the stability of the machine performance, and provide guarantee for normal and lasting production.
Although scrubbing and refueling of the machine are very important, it is more important to check the tightness of the screws and the wear of the parts when the machine is down. Vibration (loose screws), parts wear, etc. will cause shifts in the positioning of the rules. The movement is aliased, which directly affects the quality of the product. At the same time, the quality of the product should also be inspected in the production process to prevent accidents. Personnel who have suffered a mechanical failure due to poor maintenance should be held accountable. Regular maintenance will help maintain the normal operation of equipment, reduce maintenance costs, and effectively extend equipment life.
Equipment maintenance is a comprehensive discipline that involves all aspects, and it is very important for operators to have a certain basic knowledge of machinery. If the operator lacks a certain amount of basic mechanical knowledge, it is difficult to correctly use and adjust the machine. If you can rely on the mechanical principle, combined with the professional characteristics of the binding machine, carry out research and discussion, understand and master the working principle, movement law and structural characteristics of the typical mechanism of the binding machine, will have a positive help for adjustment, maintenance and maintenance in operation. . In addition, the binding output is generally based on the actual number of revolutions of the equipment, and the fixed index is calculated according to the recovery rate of 70% to 85%. Keep in mind that speed is not a good thing. The customer only cares if your product is clean and meets quality standards, and does not care about how fast your device is operating. The excessively fast operating speed (or close to the upper limit speed) and the overloaded operating speed greatly damage the service life and accuracy of the machine and should be given sufficient attention.
Long-term practice and statistics show that the incidence of failure of the binding machine for finishing presses is not static from the date of shipment. In the early stage of the delivery, the failure rate is often relatively high. This is due to the fact that the initial stage of the machine is in the equipment running-in phase (use of the equipment). With the continuation of the use of time, the incidence of mechanical failure will be significantly reduced, indicating that the machine has entered the stage of stable use (high equipment production period). Usually, this stage will remain for a long time (1 to 12 years). With the long-term use of the machine (more than 15 years), the failure rate will continue to rise again (the equipment declines), indicating that the machine is nearing the end of its life, then it is determined to update the machine.
