Application of Information Technology in Changchun Carton Factory

Information technology is a powerful means to realize low cost and high efficiency in carton manufacturing industry. Early computer systems were mainly used for data processing, such as bookkeeping, order processing, printing delivery notes and so on. Computer integrated manufacturing system focuses on assisting users to provide value-added services to their customers.

1. Computer Aided Design

Some software systems, such as IPDS and LeserComb, provide and allow users to build their own library of carton design and mold graphics, and also provide sample data of famous machine tools.

2. Product structure (BOM) and process route design.

For example, CIMPACK, a special software system for carton manufacturing industry, can help users to establish a typical product structure and a typical process flow for each product. When customers order new products, users can modify the typical design, which greatly shortens the preparation period before production.

3. Order and delivery management

The computer system can evaluate new products according to materials, specifications, dimensions and the complexity of technological process. The application of computer integrated manufacturing system can effectively arrange and record the production, inventory and delivery of orders, especially those with timely delivery. In this way, the sales department can see the progress of each order from the computer at any time, so as to take early action on events that may exceed the plan.

4. Computer-aided job planning

According to the delivery date of the order, the required materials and the production capacity of the machine tool, the computer scheduling system will automatically generate the job plan. The production dispatcher makes modifications on the electronic planning board according to the actual situation of the workshop and emergency orders. A good job plan can effectively reduce the loss of base paper, reduce downtime and frequency, and ensure the delivery date.

5. Base paper management

Different from the general inventory management software, the base paper management system can be specific to the position and production consumption of each roll of paper, and has the automatic conversion between length, weight and diameter. Usually, the procurement cycle of base paper is much longer than the delivery cycle of cartons, and the computer system can also predict the future demand for base paper.

As an indispensable part of modern logistics, packing box bears the important responsibility of containing and protecting products, and the physical performance index of packing box becomes the basis of its quality evaluation.

At present, there are basic tests on packaging cartons, such as edge pressing, bursting resistance, flat pressing, puncture, glue peeling, moisture content and compression resistance. The extension test includes a series of tests such as water absorption, stiffness, moisture resistance, printing wear resistance and vertical pressing.

1, the significance of blank holder strength test: it directly affects the supporting strength of corrugated boxes-corrugated boxes are mainly affected by gravity, and blank holder is the best way to check the blank holder strength;

The main factors affecting the blank-holding strength of corrugated board are the production technology, structure, shape and corrugated adhesive.

Definition of BHF: The vertical uniform increment (12.5mm/min) that a corrugated board with a certain height (25mm) can bear per unit length (100mm) in the corrugated direction is called BHF of corrugated board.

2. The significance of bursting strength test: it affects the lateral support strength of corrugated boxes-the bursting strength of corrugated box protection products is to assess the uniform increase of cardboard per unit area.

The test is to examine the ability of cartons to withstand static local extrusion in actual transportation environment;

Definition of bursting strength: The bursting strength of corrugated board is the maximum pressure that can be uniformly increased per unit area.

3. The significance of puncture strength test: to evaluate the energy that cardboard can withstand sudden external impact;

Definition of puncture strength: The work done by a pyramid with a certain shape through corrugated board, and the displayed energy is called the puncture strength of corrugated board.

4. Significance of adhesive strength test: insufficient adhesive strength is easy to cause delamination, which greatly reduces the compressive strength of the carton;

Definition of adhesive strength: the adhesive strength between the surface, inner layer, core paper and corrugated paper of corrugated board can be borne by separation test within a certain unit length.

Maximum peeling force.

5. Significance of thickness test: If the corrugated height loss of cardboard is too large during processing, such as die cutting, that is, indentation, grooving or printing, it will be greatly reduced.

The compressive strength of cartons, so maintaining the thickness of corrugated cardboard should be a key link in the production process;

Definition of thickness test: the height of corrugated board under a certain pressure is called thickness.

6. Significance of compressive strength of corrugated boxes: check the maximum pressure that cartons can withstand, the product protection strength of carton packaging design, and check whether cartons can withstand stacking weight;

Definition of compressive strength of corrugated box: the carton is compressed by the force generated by the uniform increase of displacement, and the maximum force that the carton can bear is called compressive strength.

Judgment of qualified compressive strength: when the compressive strength values of the three sample boxes are greater than the standard compressive strength values, the test is qualified; If one of the sample boxes is unqualified,

Then the test failed.

7. Other tests:

1. Flat compressive strength test (ISO 3035) (the force per unit area of 64.5 cm2 and 32.2 cm2)

2. Bending stiffness test (IS05628) (four-point stiffness, deformation measurement)

3. Surface splash (JIS-P8 137) (see Splash Standard Board).

4. Vertical compressive strength test (JIS-Z0403-2) (special fixture, special tool)

5. Moisture-proof performance test (GJB1109a) (250 mm * 250 mm 4 tablets, 50℃ 90% RH 90%RH 48h for 48h, and the humidity difference before and after is not more than 5%).
