The pressing line is too shallow. When the robot is folding, the molding is not in the pressing line.
Solution: In the production, we must ensure the quality of the crimping line and strengthen the production and quality inspection. Most of the machine bag products are die-cutting production, especially round die-cutting. The die-cutting department must often produce products with different widths. The wear on the anvil pad is inconsistent, and the horizontal depth is different. Therefore, check the anvil pad before production, adjust the position of the anvil pad, repair the anvil pad or replace it with a new one if necessary. There are excess creases on the flap. When the robot is folding, the molding is not in the position of the creasing line, but in the position of the crease.
There are creases on the flap, which may not matter for manual packaging, but it is definitely not a solution for mechanical packaging: There are generally two reasons for the creases on the flap. One is already existing when the plate is produced, Must be controlled on the assembly line to avoid creases. The second is that the sheet is generated during the transportation process. The single tile, especially the B single tile, must be paid attention to when manually loading the paper. The larger size of the plate is easy to produce creases when it is carried to the paper feeding section by two people. Remind the training operators to have this kind of consciousness, at the same time don't move too much at one time, it is too heavy to hold the cardboard and it is easy to produce creases.
The form of crimping line does not meet the requirements of automatic packaging lines. <br /> Solution: When designing, we should combine the characteristics of automatic packaging lines and choose different forms of crimping lines. When the standard crimping knife cannot meet the user's requirements, the crimping knife must be modified. In order to meet the requirements of flexible folding, point and line crimping knives are more commonly used on automatic packaging products. However, when the commonly used point and line knives cannot meet the specific needs of a certain position, flat cutting lines can be used for line cutting Way to solve.
Bounce back after the flap is folded <br /> Solution: Improve the quality of the crimping wire, use the above 3 methods to deal with it. Adjust the box size, the box height and the packaging height must match.
Poor adhesion <br /> Solution: Avoid printing on the adhesion part when designing, otherwise it will affect the adhesion effect. At the same time, considering the improvement of the reliability of the bonding, a point line knife can be installed at the bonding place of the ear and the rocker to improve the bonding quality. There are also paper quality that affects the bonding. Different bonding should be treated differently. Some seem to appear to be bonding problems, which are actually caused by delamination of the paper. You should file a complaint or claim with the original paper supplier.
Small and large flaps are prone to block each other during the folding process. <br /> Solution: Use the advantages of die cutting to design the grooves as beveled edges, and even the corners of each flap to be rounded. Avoid collision of the flaps during folding.
Printing quality <br /> Machine bag products are generally large in quantity, tens of thousands or tens of thousands are normal. In mass production, it may be inevitable to mix a few products with poor printing quality, but after packaging Defective products delivered to the end customers will have a bad impact, especially some large companies pay attention to brand image.
Solution: On the one hand, we must control every link of the production process, and the production must be first checked against the sample box to increase the frequency of process random inspection. Quality control strengthens inspections and warehouse inspections, and implements full inspections when necessary. Special attention should be paid to the printing slotting die-cutting machine when the machine is stopped and then turned on, the first few products of the new color can not be selected must be picked out.
Losses and complaints caused by improper product handling and handling <br /> Solution: Machine bag products are usually packed in pallets, so it is important to choose a suitable pallet. To determine several trays of different specifications according to the product's specifications and loading method, one is to consider that the size of the product may be the same as that of the tray, and the large tray and small product are close to each other. There is a gap between the two trays. The transportation process is easy to cause tilt The product is damaged and the packaging is deformed, and the small tray and large product cause damage to the bottom product. The second is to take into account the loading and unloading volume of the transport vehicle. If the pallet size is determined unreasonably, the loading and unloading volume will be reduced and the transportation cost will be increased. In addition, it is necessary to wind the pallet after filming. Although this will increase the cost, it can protect the product from damage and make the goods delivered to the user intact. It is cost-effective to consider as a whole.
