Pack Machine/Computer Production Management System

CPMS 300C use the Windows PE to do the development, which is 5 to 10 times more stable than the normal Windows system.

Summarize of produce management

Before install the produce management system, most of the operation are depend on the operators experience, skill and the communication between the operators, so it will be easy to bring the following problems:

Cumulative paper volume of the span bridge:

As the operators neglect, let the cumulative paper volume of the span bridge become too many or too small. If its too many, the half finished goods can not dissipate the heat and produce the steam then press each other become distortion, under this situation, the flute will reverse or fall down, even bubble and degumming, all of these will cause the unnecessary wastage. If its too small, the paper will be snapped and causes stop running unnecessary. If day output is 40,000 M and each day produce 100 M badness product as the cumulative paper volume of the span bridge, it means the wastage rate is: 100/40,000=0.25% .

Error of changing paper:

Human calculating usually estimate by experience, normally, in order to make sure the output is enough, the wet part will have more paper than actual situation, its near 10 M to 100 M as spare. If each day change paper 30 times: 30*20/40,000=1.5% .

Error of changing order:

Because human can not control the rotary cut-off machine, slitter & scorer accurately when we change the order or change the flute. So, if each day change order 50 times, each time the error is 5 M, the wastage rate: 50*5/ 40,000=0.625% .

Stop running:

As the workers have to operate the machine, another hand, they need to communicate and assort with the other workers, so usually it will stop running as the badness communication, which will cause a great deal wastage and debase the output and efficiency. For example, according to normal speed 90m/ M, each day stop running 20 times, each time waste20 M, stop running 3 minutes, the wastage will more than 20*20/40,000=1% , average speed is: 90*(8*60-20*3) / (8*60)=79m/M , debase output: (90-79) / 90=12% .

Wastage of starch:

Because manual way can not adjust the glue thickness immediately according to the paper quality and running speed, which will cause the papers agglutination not good or too much starch, it means waste the paper and starch

Over rely the teachers experience, will bring some trouble when do the training or on the management.

Do the report forms by manual way will exist suspicion and this way can not reflect and solve the problem immediately:

When one of the orders exist problem but can not check this order whether finished or not; when produced; the producing quantity and so on. Another thing, not only the human calculating does not nicety, but also the data and workload are very big.

The producing manager and order operating worker can not hold the producing locales status, which let them impossible to make a decision immediately, for example whether theres still time to add order; when begin producing; when deliver the products, and so on. All of these will let the worker miss opportunity to add order then can not arrange normal production scheduling.

All the work will finished by human, which will waste the human resource and add more time.

Whats the function of the producing management system in the whole process of the corrugated production line? How it can operate and improve the manufactorys producing management? Take these questions and go through each part of the corrugated cardboard box production, we will open out the whole structure and function of the producing management system:

Base paper:

Actually we use the paper roll to produce the carton, at the first beginning, the machine press the base paper to corrugated paper then glue another base paper, it looks simple, but this process include many knowledge, now we introduce it from the first step.

Firstly, we need to talk about the base paper from the storehouse: The manufactory need to record how many types of base paper in the storehouse and how about the papers width. Some manufactory will use one character to represent the type, such as A, B, the other will use 6 characters to mark it, for example 125MPS, 125 represent the weight conversion cardinal number and MPS means the supplier. Whatever use which way to manage, the most important thing is after the manufactory receive the order, do they can react whether they have enough stock to satisfy the production immediately, when there has no enough stock, how much base paper should order or which paper can be replace the original? All of these problem can be solved by the producing management system.

Smooth producing permutation and combination:

Manufactory must handle many orders in one day, in order to speedup production, most of the manufactory will produce the same flute together, for example: (  C) (C) (C) (B) (B) (B) (CB) (CB) (CB) (ECB) (E); and the bad permutation is: (C) (B) (C) (E) (B) (C).

Production management system can calculate and realign the order flexible then print the Base paper prepare form for the manufactory in order to help the workers do the preparative, the flute type, material and quality, width will be the factor in the calculating. Here, production management system not only help the operator prepare the base paper, but also help them estimate when should change the paper and this also will be one of the point to remind the system need to change the paper automatically.

Print the statistical report of the production management system:

Production just like an exam, the most important thing is get a good achievement. One day, one week or one month, also reflect the health status of the workers and equipments. People can communicate with the director when the work has problem. But the equipments can not disclose any message except the fixed alarm system, so we just can via the reports to calculate the people and equipments whole performance, this will connect with the production management system.

For example:

Production statistics: it can indicate the total working hours, total working hours, total weight, total length, average production speed, badness whole ratio, production data of each flute, production data of glue machine and each local host.

Production daily sheet: it can check the production schedule of each specific day and each workers working performance.

Volume label: when we finish the product and seal pack then prepare delivery. In order to pick up the goods quickly and exactly, must stick the identification label on each pack.

Dry part, slitter & scorer:

After the glue machine, the corrugated paper will through the hot section bed then finish the dry part and come into the slitter & scorer. The slitter & scorer will fixed the distance and quantity of the knives according to the cutting quantity and cutting distance. Normally, slitter & scorer will arrange the five specs distance and quantity of the knives, this way can let the machine change the order quickly when its near changing. So, each time do the changing, we can use online communication send the following five orders to the slitter & scorer in order to save time, when the worker is operating the machine, they must pay attention of the side paper whether is too narrow and cause the badness products, so production management system will remind the operator some of the orders side paper are too narrow in advance..........
