571. How should the binding process for printing be established?

A: According to the actual situation, the quota for the binding process after printing is divided into two parts, namely equipment quota and manual quota.
(1) The system of fixed equipment quota for equipment shall be based on the actual conditions of the number of normal revolutions per minute (actual production quantity and capacity) in accordance with the conditions of the equipment. The recycling rate of binding equipment is about 80% for a single machine, about 70% for a linkage production line (the percentage of the above recycling has been removed, and the machine has been downed, etc.), and this is taken as the basic figure, and the actual situation can be used to produce a comparison. Reasonable quota.
(2) Manual Operation Quotas for manual quotas can be determined by measuring the basic figures using three “1+1 divided by 2” methods: 1 Adding the historical maximum and minimum output and dividing by 2 to obtain the historical output average Number; 2 Add the highest and lowest output in recent years by dividing by 2 to get the average number of production in recent years; 3 Divide the historical and recent average output by 2 to get the basic parameters of the manual operation quota. Based on the basic parameters, according to the actual situation, the micro-motion is the number of manual operations.

572. What should be noted when formulating binding quotas?
Answer: Stapling is a very complex process. There are a large number of fixed items. When setting up, it should be noted that: (1) There is a trial period, a high yield period, and a decline period for equipment quotas. (2) The manual operation quota generally does not decline, because manual operation has new improvement methods at any time, and practice makes perfect, faster and faster. (3) The majority should be completed or over-completed when setting quotas, and a few will be able to complete them through hard work. Attention should be given to the majority of the people after discussion through accreditation (democratic concentration). The implementation should also be gradually revised and improved during implementation. .

573. What is the quality inspection system?
A: The quality inspection system is the inspection of finished products and semi-finished products.

Check and acceptance system. The quality inspection of the binding process includes self-inspection, mutual inspection, sampling inspection, and layer-by-layer inspection in the actual operation.

574. What are self-checks, mutual inspections, sampling inspections, and inspections of upper and lower layers?
A: Self-inspection is the self-inspection of the finished product or semi-finished product processed by the producer; mutual inspection is to ensure the quality, a production line, a small process to carry out checks between each other; sampling is the quality of off-production or not off-production The inspector shall check the number of finished products or semi-finished products produced by the operator under regular or irregular conditions. The upper and lower layers shall also be referred to as layer-by-layer checks, that is, the next process shall check the upper process.

575. How to carry out sampling inspection work in the workshop?
Answer: Sampling can be conducted regularly or irregularly. Each time a general sampling of 100 sheets (posts or volumes) is performed, the number of unqualified items is calculated as a percentage. Each sampling should be recorded (the number of people being sampled should be averaged on a monthly basis), and sampling inspections should be announced on time, good quality should be praised or rewarded, and poor quality should be criticized or punished. Never eat a big pot of rice, only rewards and punishments can ensure the healthy development of the company.

576. What are the conditions for quality inspectors?
A: Quality is the life of an enterprise. The quality of the product is the guarantee for the survival of the enterprise. The quality inspector is responsible for the quality of the product quality of the enterprise. Therefore, the following conditions must be met:
(1) It is necessary to familiarize with and master the post-press binding procedures and related quality standards, such as national, regional, and corporate standards for quality products and qualified products; (2) To be familiar with the process flow of the processes to be controlled and Process technology; because of quality problems and process technology are inseparable; (3) quality problems should be solved in the semi-finished products; do not wait until the finished product or found out before found problems, each process must be strictly controlled product quality Guaranteed; (4) To do quality inspections should have a sense of justice, good and bad, and enforce the law impartially, and should help the workshop to find out the causes of the quality problems and find measures to solve, so that the workshop can be processed smoothly.

577. What is a process file system? Why do you need a process file?
Answer: The process file system refers to the preservation of product sample books made with different technological means (especially the process is more difficult). The process file is an indispensable system for process management. It can preserve historical data, promote the improvement of process technology and product quality, and can also play a role in educating new employees and product propaganda.

578. What is the equipment file system?
Answer: The equipment file system refers to the record that was established when the equipment entered the factory. The contents are roughly as follows: (1) equipment name, manufacturer and source; (2) date of incoming plant; (3) equipment operation (new or used equipment); (4) maintenance and repair times and times after use; (5) Parts wear and replacement; (6) Common faults and accidents occurred. These must be documented to understand the use and life of the equipment.

579. What is the equipment inspection maintenance system?
Answer: The equipment inspection and repair system refers to the maintenance and maintenance of the equipment during the work, that is, after the equipment is used, the equipment is cleaned and cleaned and the inspection performed when the equipment is cleaned.

580. How to carry out equipment inspection maintenance?
Answer: The inspection time of the equipment used for binding is generally one class (machine operation for 8 to 12 hours) should be checked every two weeks; two or three shifts (machine operation for 16 to 24 hours) should be checked every week. once. Each wipe should be wiped clean, windy, smooth, thorough inspection, and add solid or liquid lubricants, in case of need to replace the vulnerable parts should be resolved by the way, to avoid problems after boot affect production.
The equipment used for binding, including stand-alone machines and linked production lines, is usually used for 2 to 4 hours (2 hours for small singles and 4 hours for large equipment and linked production lines).

581. How to carry out equipment overhaul?
Answer: The equipment's medium and overhaul refers to the necessary maintenance when the equipment is operated for a certain period of time or when it encounters special circumstances. First, a senior engineer or technician-level leader is required to fill in the report of the inspection and repair requirements. The director of the equipment department or the technical equipment in charge may then conduct the discussion, study, plan, and approval. During the inspection and repair, the leader of the above professional title follows the whole process. When the equipment is inspected and qualified, the two parties can test and operate the machine after normal inspection.

582. What is a safe and civilized production system? What does it include?
Answer: The safe and civilized production system refers to the system formulated to prevent the occurrence of various accidents and ensure the normal production order of the factory. Safe and civilized production system is one of the indispensable systems for modern standardized production. Its contents include the following aspects:
(1) Establish or improve safety operation procedures, factory regulations, factory regulations, etc. (2) The layout within the factory floor is reasonable and should be rationally arranged based on the needs of the process flow and the convenience of operators. (3) The location of semi-finished or finished products stored in the workshop should be reasonable. They should not be placed close to walls, windows, heating, etc., and they must not be placed in the open air to avoid damaging the rationality of the moisture in the paper and make the books wrinkle uneven after processing. (4) Reasonable equipment placement, such as good lighting (preferably direct light), convenient transportation, etc. (5) Workshop equipment, worktables, etc. are neat and clean, with no waste paper sheets, paper hair, grease, and other dirt, and are strictly prohibited from being piled up and thrown in a random manner, resulting in dirty and unfavorable results in the garbage workshop.
