In recent years, with the continuous reform and development of the printing industry, the binding process of post-press processing has gradually formed a mechanized, coordinated, automated operation process from an outdated manual operation process, and the equipment has also been continuously updated. However, due to equipment maintenance, lack of maintenance technology, and inadequate management, the machine could not operate normally, and delays in the delivery of books or the quality of books and magazines have occurred. Here the author talks about how to carry out the maintenance of the binding equipment and maintenance management, talk about personal views.
Economic Significance of Maintenance and Management of Binding Equipment
Although the maintenance and repair of equipment does not produce direct economic benefits, it has an important role to play in extending the service life of equipment and giving full play to its potential. For example, our ZYH670A folding machine has already reached the end of its useful life, but it can still be used normally through maintenance and repair. The treatment measures are as follows:
(1) Dismantle all folding rollers to make them round so that they meet the requirements when adjusting the gap.
(2) Check and adjust the gap of gear turning roller to check if the bearing is damaged.
(3) Check for loosening and damage of the keys and pins of the connecting parts, and replace damaged parts.
(4) After the maintenance of the whole machine, clean the oil circuit, air circuit, and replace the lubricating oil.
After repairs, the equipment life can be extended by 3 to 5 years. At that time, if the exchange of equipment used for trade-in required about RMB 15,000, and the factory spent only 2,000 yuan, the accuracy and function of the machine will be restored.
Another example is the BBY40/5 disc packer purchased by the factory in 1998. The use of the BBY40/5 disc packer in 2002 caused severe wear of all components and the package book did not meet quality requirements. All the loose keys and pins are then reworked, the worn bushings are replaced, and the loose gears are readjusted. From demolition and processing of parts to re-installation, a total of less than 2,000 yuan was spent, saving a lot of money.
Do a good job of technical personnel training
In recent years, the binding process has gradually taken mechanization and automation. According to the author's understanding, major colleges and universities across the country have not set up a specialized specializing in binding machines. The employees are learning and accumulating experience while working. Therefore, in the introduction of binding equipment must pay attention to the training of technical personnel, and strengthen the technical training of staff. The training content can be divided into two aspects: on the one hand, related technical theories required for technical maintenance; on the other hand, it is aimed at the principle analysis of the equipment control system, the specific device function and technical training for detection and maintenance. In addition, special attention should also be paid to the on-site training of technicians in the actual installation and operation of the machine. It is advisable that the supplier of the equipment be allowed to perform two on-site trainings for the technical and maintenance personnel of the plant, and how to maintain and prone to the problems of the equipment. Detailed explanation.
Emphasis on experience accumulation and mutual exchange
When a machine fails and the machine stops, the maintenance personnel must determine the location and type of the fault (electrical fault or mechanical fault) in the shortest time possible, find out the cause of the fault and the source of the fault, and then replace the corresponding faulty component and remove the fault. malfunction. Therefore, maintenance personnel must understand the mechanical structure of each part of the equipment, the electrical control principle, the structure and working principle of the control device module, and so on. Through practical maintenance work experience, master various judgments and detection methods of fault phenomena. At the same time, maintenance personnel should discuss and communicate more to improve their overall technical level.
Create a device file
Equipment from the signing of the purchase contract, it is necessary to proceed with the establishment of equipment files, the purchase contract, technical information, machine instructions, acceptance orders and related drawings income files. In the course of using the device, the fault phenomena, causes, and troubleshooting as well as the hidden troubles found in the normal maintenance process are recorded in the device file at any time, so that the state of the device will have a more comprehensive The understanding helps to determine the cycle of the fault and the type of occurrence and early spare parts preparation. A spare parts store should also be established, with special personnel responsible for management, and supplemented in a timely manner to ensure that spare parts for repair can be supplied in a timely manner.
Establish equipment maintenance system
The binding equipment should also establish a reasonable equipment maintenance system and a preventive-based equipment management system, so that the equipment is in a good state of operation.
(1) Establish equipment management system. To establish a four-level management system for the factory, equipment, binding workshop, and machine group to ensure the effective implementation of various systems and measures.
(2) Formulate a system plan maintenance system.
(3) Develop a three-level maintenance system for equipment to make it operational.
(4) Strengthen equipment maintenance knowledge and safety production education so that operators can truly understand and achieve “three good†and “four meetings†during specific maintenance.
(5) Formulate equipment safety operation rules, daily cleaning and maintenance rules, lubrication management system, etc., so that the cleaning and lubrication work can be fixed, qualitative, quantitative, regular, and fixed.
(6) Establish a scientific and reasonable assessment of equipment integrity rate and link it with rewards and punishments.
(7) The establishment of an on-site management team to implement regular inspections and evaluations of workshop equipment and the implementation of various equipment management systems.
