Discussion on Improving the Product Replacement Efficiency of the Glass Bottle Line-type Bottle Making Machine ①

The speed of product change is a manifestation of the level of bottle-making technology of glass bottle companies. The scene we sometimes see is: the scene is full of turmoil, molds and accessories on the floor, hot and cold glass bottles flying around, this group of materials jumps, and the pair of pliers arms can’t turn over; this group of pliers can’t come out. That group of blowing heads is blocked; this group of squeezing bottles, and that group of molds can’t be closed…. The work that should have been done in one hour, the machine is still not stable in two hours, sometimes the product can not be produced in half a shift, and it also happens that one or two shifts of a more difficult product fail to produce qualified products. The resulting loss over time is huge. These phenomena indicate that bottle-making technology is immature and bottle-making management needs to be improved. Over the years, we have been committed to improving the research of bottle-making technology, especially on how to quickly replace products.

1. Preparations for quick product replacement must be detailed.

After receiving the notification of product replacement, the leadership team of the bottle-making workshop analyzed the technical points and difficulties of the new product according to the standard, checked the historical records and carefully checked the special requirements of the user, and formed the idea of ​​this product replacement. A deputy director Arrange for mold repairers, glass bottle manufacturing team leaders, operators, and maintenance workers to implement their respective preparations.

1.1 The work of the deputy director of bottling.

1.1.1 Responsible for notifying the relevant machine team leader and mold repairer of the specific time and product number of the replacement product.

1.1.2 Provide the necessary measuring instruments for the product replacement team in accordance with the product standard. Such as volumetric sample bottles, collars, stopper gauges, glass bottle body calipers, etc., so that the control of product technical parameters is more consistent before the machine, ensuring stable product quality and increased output.

1.1.3 Write the product standard on the whiteboard in front of the machine, and indicate the relevant requirements and precautions at the same time, so that the line machine operator can clearly understand the product characteristics and accurately take control measures.

1.1.4 Sampling inspection of the molds and accessories sent to the machine, and timely feedback to the relevant departments if any problems are found. In this way, it can not only avoid the loss of unqualified molds on the machine, but also check whether the mold repairers and the bottle-making team leader are in place to check and accept the molds.

1.1.5 Choose a suitable mold lubricant. Die lubricants should be selected according to the characteristics of the products on the machine, the defects that may appear in the production process, and the special requirements of users.

1.1.6 Determine the mechanism to be adjusted and the timing of actions. This requires careful comparison of various technical parameters and specific product conditions of the products on the machine and the products to be used on the machine.

1.1.7 Adjust the drip temperature fifteen minutes in advance. This requires timely adjustment of the forehearth heating and cooling system according to the product structure and output changes of the machine to ensure the dropping temperature of the machine product.

1.2 The work of mold repairers.

1.2.1 Pick up qualified molds and related accessories in time after receiving the notice from the workshop.

1.2.2 Carefully and carefully inspect whether the molds and accessories are qualified. When inspecting the mold, pay attention to the following points: First, ensure that there is no obvious wear and bump on the edges of the finished, preliminary mold and die; second, ensure that the mold cavity is clean and free of damage, and meet the requirements of the machine; third, ensure that the accessories are correct, Normal; Fourth, ensure a good cooperation relationship between the molds.

1.2.3 Carry out the necessary repairs to the mold with the problem. This needs to be fed back to the workshop and received instructions from relevant departments before proceeding.

1.3 The work of the bottling team leader.

1.3.1 Recheck one by one whether the finished, first mold and die before being sent to the machine are normal, and whether they cooperate well with each other.

1.3.2 Check the accessories carefully to ensure that the air holes of the bulkhead, core and positive blowing head are unblocked and not blocked by oil or glass, and ensure that the inner blow tube is correctly placed on the positive blowing head.

1.3.3 Carefully check the jaws of the tongs to ensure that the size of the jaws of each pair of tongs is accurate, and the two halves are in good meshing.

1.3.4 Arrange personnel to preheat the finished mold, the first mold and the die at an appropriate time. For the new mold that is used for the first time, it must be preheated and sandblasted before being preheated again.

1.3.5 Ten minutes before the product is put on the machine, check the shelf pan balance scale in front of the machine, and select the appropriate weight according to the weight of the product on the machine, so as to accurately control the product weight and capacity.

1.3.6 Check whether there is enough water in the discharge tank to ensure that the glass liquid flows smoothly when it passes through the discharge tank during shutdown.

1.4 The work of the operator.

1.4.1 Prepare the necessary tools when changing products, such as special handles for prototypes and prototypes, special tools, etc.

1.4.2 Classification and fixed placement Place the mold accessories of the machine-made products in the designated position for easy access at any time.

1.4.3 Put the preheated molds, initial molds, and molds in a fixed position after lubrication. The finished molds are grouped and placed on the ground in front of the bottle conveyor, the mouth molds are placed on the front platform of each group of bottle clamping mechanisms, and the preliminary molds are grouped and placed on the ground behind the rowing machine.

1.4.4 Make suitable oil brushes as required to facilitate timely and correct use of mold lubricants.

1.5 The work of maintenance workers.

1.5.1 Prepare the accessory equipment that needs to be replaced when changing the product, such as tongs, funnel arm, etc.

1.5.2 Transport the clean accessory equipment in good condition to the front of the row machine.

1.5.3 Prepare relevant spare parts for necessary minor repairs when changing products according to the workshop arrangement.
