The speed of glass bottle manufacturers in the replacement of products is the embodiment of the level of bottle making technology in bottle and glass enterprises. The sight we sometimes see is: the scene is a mess, the molds and accessories on the ground, the hot and cold glass bottles fly, this group of jump materials, the set of pliers arms can not be turned over; this set of pliers can not bottle, The group of blow heads are blocked; this group of squeeze bottles, the mold can not be closed. The work that should have been done in an hour, the two-hour machine is still unsettled, sometimes half a class can not produce the product, and a product with a slightly more difficult one or two classes does not produce a qualified product. The resulting losses over time are enormous. These phenomena indicate that the bottle making technology is not mature and the bottle management needs to be improved. Over the years, we have been working hard to improve the research of bottle making technology, especially in the rapid exploration and summary of how to quickly replace the product.

1. Quickly replace the product preparation work.
After receiving the product replacement notice, the leading team of the bottle making workshop analyzes the technical points and difficulties of the new products according to the standards, checks the historical records and carefully checks the special requirements of the users, and forms the idea of ​​changing the products. Arrange to repair molders, bottle squad leaders, operators, maintenance workers, and implement their own preparations.
1.1 The work of the deputy director of the bottle.
1.1.1 Responsible for notifying the relevant machine squad leader and the specific time and product number of the repairman to replace the product.
1.1.2 Provide the necessary measuring instruments for the replacement team according to the product standard. Such as capacity sample bottles, collars, plug gauges, bottle calipers, etc., so that the control of product technical parameters is more consistent in front of the machine to ensure product quality and production.
1.1.3 Write the product standard on the front whiteboard, and indicate the relevant requirements and precautions, so that the operators of the row machine can clearly understand the characteristics of the product and accurately take control measures.
1.1.4 Check the molds and accessories sent to the machine before the machine, and find the problem and feedback to the relevant departments in time. In this way, it can not only cause the loss of the machine on the unqualified mold, but also check whether the work of the mold repairer and the bottle squad leader is in place.
1.1.5 Select the appropriate mold lubricant. The mold lubricant should be selected according to the characteristics of the machine, the defects that may occur in the production process, and the special requirements of the user.
1.1.6 Determine the mechanism and action timing to be adjusted. This requires careful comparison of the technical parameters of the machine products, the products to be prepared, and the specific products.
1.1.7 Adjust the drip temperature 15 minutes in advance. This requires timely adjustment of the channel heating and cooling system according to the structure of the machine and the change of the discharge amount to ensure the temperature of the drip of the upper machine.
1.2 The work of the molder.
1.2.1 Pick up qualified molds and related accessories in time after receiving the workshop notice.
1.2.2 Carefully and carefully check whether the molds and accessories are qualified. Pay attention to the following points when testing the mold: first, make sure that the edges of the mold, the initial mold and the die are not obviously worn and bumped; the second is to ensure that the cavity of the mold is clean and free of damage and meet the requirements of the machine; the third is to ensure that the accessories are correct. Normal; the fourth is to ensure a good mating relationship between the molds.
1.2.3 Perform necessary repairs on the mold in question. This needs to be feedback to the workshop and received instructions from the relevant departments before proceeding.
1.3 The work of the bottle squad leader.
1.3.1 Check whether the Cheng, the initial mold and the die before being sent to the machine are normal one by one, and whether the cooperation with each other is good.
1.3.2 Carefully inspect the fittings to ensure that the air vents of the bulkhead, the core and the blowhead are unobstructed, and are not blocked by oil or glass, ensuring that the inner blowpipe is properly placed on the blowhead.
1.3.3 Carefully inspect the jaws of the jaws to ensure that the jaws of each jaw are accurate and the two halves are well meshed.
1.3.4 Arrange the personnel to pre-heat the finished mold, the initial mold and the die at the appropriate time. For the first time, the new mold should be preheated and then preheated by sandblasting.
1.3.5 Ten minutes before the product is on the machine, proof the front plate balance of the machine, select the appropriate weight according to the weight of the machine, in order to accurately control the weight and capacity of the product.
1.3.6 Check if there is enough water in the discharge tank to ensure smooth flow of the glass liquid through the discharge trough when the machine is stopped.
1.4 The work of the operator.
1.4.1 Prepare necessary tools for changing products, such as special handles for special molds, special tools, etc.
1.4.2 Classify and position the mold parts of the machine products at the designated position so that they can be accessed at any time.
1.4.3 Place the finished, initial and mouth molds that have been preheated beforehand and place them in a fixed position. The mold group is set to be discharged on the front floor of the bottle conveyor, and the die is placed on the front platform of each group of pliers. The initial molds are grouped and placed on the ground behind the row machine.
1.4.4 Make suitable oil brushes as required to facilitate timely and correct use of mold lubricants.
1.5 The work of the repairman.
1.5.1 Accessories that need to be replaced when the product is ready to be replaced, such as a pair of tongs and a funnel arm.
1.5.2 Transport the clean, in good condition accessory equipment to the front of the line machine.
1.5.3 According to the workshop arrangement, prepare necessary spare parts for the necessary minor repairs when changing products.
2. The division of methods and science is clear.
2.1 To ensure faster product change speed, proper product replacement methods are required. We take the replacement method twice, that is to say, we change the three groups first. At this time, the material weight of the product is subject to the on-board product, and the three groups that have not been replaced are normally produced. Re-adjust to the new product bottle weight, and then change the other three groups. For the eight groups of machines, this is also the case for two changes.
2.2 In order to achieve rapid replacement of products, a reasonable and clear division of labor is also necessary.
2.2.1 During the entire product change process, the deputy director of the bottle is responsible for the supervision and management coordination work, paying close attention to the details and possible changes, and immediately correct the problems.
2.2.2 The squad leader of the row of machines pays attention to controlling the weight of the product, and discovers the defects of the product in time and eliminates it.
2.2.3 Three rows of machine operators on each machine segment cooperate with each other to replace them. One of the operators who are more familiar with the structural performance of the row machine is replaced on the initial mold side. The operator should be careful and always control. The rhythm of good product replacement, ensure that the person and machine in the machine segment are in a safe state during each step of operation; another operator stands on the platform of the bottle conveyor for replacement, the operator must be careful, observe the machine carefully. The change of the segment action must ensure that the segment is in a stable position during the operation replacement; there is also an operator standing in front of the bottle conveyor, the operator should concentrate on the delivery of the die and accessories. And timely replacement of the mold base and the pliers, timely adjustment of the mold base mechanism and the clamping mechanism height.
2.2.4 The workshop maintenance worker is responsible for the object cleaning work. It is necessary to promptly remove the molds and accessories of the lower machine from the work site to ensure the neatness of the workplace, convenient and safe operation.
3. Operational program optimization.
The ideal operating procedure plays a crucial role in increasing the speed of product change, which is the most critical part of the product change. Our operations are roughly divided into four areas.
3.1 to stop properly. When the workshop leader issues the command to start the replacement of the product, the operator on the initial mold side of each machine section stops the material immediately, and the last bottle in the mold is clamped out. When the mouth clamp is turned over until the mold is opened, the machine is stopped. Section work, then operate the relevant air circuit, so that the pliers and the clamp are in the open position, and put a special collar at the meshing of the jaw mechanism gear and the flip mechanism rack to avoid unnecessary return of the jaws. hurt.
3.2 Replace the die, the blow head, the pliers, the sleeve and the core. The initial mold side operator operates the relevant gas path, replaces the core and the sleeve, and the operator standing on the platform of the bottle conveyor replaces the die and the blow head. After the replacement is completed, the operator on the first die side takes the mouth. The collar of the jaw mechanism gear and the gear of the turning mechanism is engaged, the relevant gas path is operated, and the mouth clamp is returned. At the same time, the operator standing in front of the bottle conveyor removes the mold bottom, replaces the clamp bottle clamp, and replaces the clamp bottle. When clamping, the opening of the bottle clamp should be compatible with the size of the bottle mouth of the upper product.
3.3 Perform the replacement of the initial, mold and related tongs. When changing to the first mold and the tongs, it is necessary to use the mold handle and the tongs handles made in the workshop, which is safer. After the replacement is completed, the operator on the initial mold side operates the relevant gas path to close the mold, and the tongs are in the inverted position. At this time, the operator in front of the bottle conveyor should adjust the height of the mold bottom in time.
3.4 Calibration calibration of each agency.
3.4.1 Correction of the jaw clamp mechanism. After closing the molding die, the calibration of the jaw mechanism is started when the jaw is turned over to the mold. Before the calibration, the gas path of the control jaw is turned over, the gas path returned by the control jaw is disconnected, and the mold is ensured. There is no mold bottom placed, which is a prerequisite for accurate correction of the jaw mechanism. The person standing on the platform of the bottle conveyor should independently correct the height of the pliers. After the correction, the gap between the mold and the die should be kept at about one millimeter. This is an important part of our quick change of products.
3.4.2 Flue gas mechanism and funnel mechanism correction. While correcting the tongs arm, the operator on the initial mold side immediately replaces the boring head and the funnel and immediately operates the relevant air circuit, closes the initial mold, and allows the deflation head to be closed under the air to correct the flutter mechanism and the funnel mechanism. When correcting these two mechanisms, be sure to place the pliers in the inverted position. Also, be sure to correct the flutter mechanism before recalibrating the funnel mechanism. When calibrating the funnel mechanism, first let the funnel fall directly above the initial mold, then let the flap fall onto the funnel, then adjust the funnel arm and leave the funnel about two millimeters away from the funnel arm.
3.4.3 Correction of the positive air blowing mechanism. After the hopper mechanism is corrected, the operator on the initial mold side operates the relevant gas path, opens the initial mold, and returns to the tongs, allowing the positive blow head to fall above the molding die to start correcting the positive blowing mechanism. When correcting the positive air blowing mechanism, the positive air blowing head should be pressed tightly at the center of the molding top groove.
3.4.4 Core cylinder height correction. When correcting the positive blowing mechanism, the operator on the initial mold side is responsible for adjusting the height of the core cylinder. It should be noted that when adjusting the height of the core cylinder, the jaw should be in the fully returned position, and the height of the jaw mechanism is not required. When adjusting, the height of the core cylinder should not be adjusted.
3.4.5 mold bottom height adjustment. After the above relevant mechanism is corrected, the operator on the first mold side operates the relevant air circuit to open the mold. The operator in front of the bottle conveyor is placed in the bottom of the mold and adjusts the height of the mold bottom to the appropriate position. The height of the mold bottom should ensure the mold switch. freely.
After the parts are replaced, the mechanism is turned on and the unit is turned on.
