[Chinese Packaging Network News] Corrugated cardboard line scheduling, also known as scheduling, currently divided into two manual scheduling and computer program automatically. Scheduling is based on the customer's order requirements of the base paper material, type, number of layers, and specifications for system classification, so as to achieve the best arrangement and combination of technical means. The reason why scheduling is a technical means is that it is a key link in the production of corrugated cardboard lines for packaging companies. The utilization of base paper, the production efficiency of tile lines, energy consumption, and even the fatigue of employees are directly related to it. The importance of scheduling is evident here. Scheduling has now paid attention and extensive attention for many packaging companies. At the moment when companies are generally aware that improving ergonomics and reducing costs are effective ways to ensure profit growth, it is of positive and significant significance.
For this reason, some paper packaging companies have not hesitate to install tile-based automatic scheduling software (some ERP systems have scheduling procedures), and some companies hire high-paying professional schedulers to fight. Whether it is installing software or hiring professional schedulers, each has its own advantages and disadvantages. Although the current automatic scheduling software can help us get rid of tedious labor and reduce labor costs, but in the selection of materials, the paper balance of different lengths of paperboard can not be automated, yet the software technicians need to develop and innovate; manual scheduling It can solve the problem that the automatic scheduling can not be solved for a while. It is flexible and flexible for emergency order insertion, and the adjustment of the corrugated board beyond the theoretical range can be adjusted as desired. The inadequacy is easily changed with the emotions and professional qualities of the scheduler. , In addition, it also increases labor costs, especially in today's tight human resources, and skill talents are difficult to recruit today, even more frustrating and annoying. However, the use of manual computer tools for scheduling is still widely used by packaging companies. Obviously it is due to automatic scheduling, the program is not flexible enough, and there is still a place where the software can not completely replace the human brain. If one day automatic scheduling really can replace manual scheduling, it will be a "revolutionary" progress in the packaging industry, with epoch-making significance. Since manual scheduling is used by most packaging companies, and the packaging industry is still inseparable from it, let's discuss scheduling issues and scheduling techniques.
What should be noted in the scheduling of paper packaging tile lines Corrugated cardboard line scheduling must pay attention to the following matters:
1. Utilization of base paper: In order to increase the utilization rate of base paper, it is necessary to consider not scheduling frequent replacement of base paper, and to try to match orders that can be spelled at the same width once and for all. Even if an urgent single insert is encountered, another one has been replaced. As for the base paper of the door width, as long as the materials are the same, it is possible to place the urgent single row and it looks like a waste of a few centimeters or dozens of centimeters of base paper, but the comprehensive accounting not only does not waste, but saves the time for replacing the base paper and the electricity fee. , energy consumption, and paper waste due to paper change. In addition to considering the shrinkage of the base paper, some base papers, especially those with large moisture content, undergo preheating and traction. The effective width is generally around 1-50px. If you do not understand these, the actual production will show slitting. Fringe, cutting is not in place, or the opening of cardboard is insufficient, it is bound to cause waste.
2. The tile line equipment performance: corrugated cardboard line type match, the effective production width, the number of points cut, the minimum and maximum pressure line spacing, cross cutting single or double knife, stacking mechanism, the maximum speed, and the degree of automation, etc. considering. Otherwise, scheduling and actual disconnect will cause frequent changes and affect normal production.
3. Technical level and collaboration of tile technicians: This is very important. When faced with an order of less than 25px trimming and bad paper pull, tile technicians are skilled, good teamwork, and can avoid revisions. The waste caused by missing paper and frequent paper breaks at the boot, of course, also avoids the lack of quantity due to waste and the need to re-schedule patches.
4. Turn on time of tile line: Determine the total length of the schedule according to the average speed and working time of the corrugated board production line. If one class produces, we must first place the urgent single in front, followed by the most recent delivery date, and then According to the delivery schedule. Two-shift or three-shift production can be scheduled according to the order delivery schedule. It is worth mentioning here that it is necessary to pay attention to planned start-up time. If the order is sufficient, the dissatisfaction will not only cause production pressure on the next day, but also cause down-stitching and bad work for the next process; if the order is insufficient If the boot time is too short, it will bring waste to the company.
5. Degree of fatigue of employees: This is closely related to the length of boot time. Employees work continuously for a long time, physical fatigue affects the efficiency of the work, and it is dangerous to endanger the safety. There is no special case that the class should not exceed 8 hours. 6. Scheduler's Responsibility: A qualified scheduler is actually a good dispatcher. He (she) should first have a good professional quality, not affecting the work with personal preferences, personal emotions, and personality. They are sensitive to numbers and have patience. They can consciously perform the duties of the scheduler: According to the production schedule, they can master the production schedule in time, avoid the next process, and do not transfer the process difficulties or trouble to the next process. It is reasonable and effective. Make use of the base paper width to avoid unnecessary waste as much as possible.
China Packaging Network editors believe that the importance of scheduling is of vital importance to manufacturers. It can not only effectively promote the production schedule, but also improve the production efficiency, so that production can be carried out more smoothly, with high efficiency and low consumption. The production has a firm foothold in development.
