Summary:Automatic filling machine by the integration of automatic control technology, communication technology, electromechanical technology in one of the high-efficiency automated filling production line. The PLC is used for monitoring and control, and the rejection device can automatically and efficiently push the non-aluminum foil encapsulated drums to the isolation area for subsequent processing, which improves the continuity and production efficiency of lubricant production, ensures the safety production and packaging quality, and has great practicality.
0Introduction
Weighing induction aluminum foil sealing has been widely used in medicine, pesticides, food, cosmetics, lubricants and other industries, this technology is also the contemporary international recognition of the advanced sealing means, China Petroleum Lubricating Oil Company Kunlun Tianli and other brands of lubricating oil filling 4L also use this means of sealing. Aluminum foil sealing machine is the use of the principle of weighing induction, the aluminum foil on the mouth of the barrel instantaneous generation of high heat, and then fused to the mouth of the barrel, so that it can achieve the function of sealing, which is used in the aluminum foil used by the barrel cap suppliers beforehand with adhesive in the cap, in the sealing process placed in the mouth of the barrel, but in the actual production of filling process due to certain reasons, some of the aluminum foil in the barrel cap will be off before sealing the cap, resulting in sealing the cap with no wrong foil, can not achieve the effect of encapsulation, in the transport of the 4L lubricants, such as Kunlun Tianlun also use this means of sealing. The effect of encapsulation could not be achieved, which caused oil leakage during transportation. The original 4L metering filling machine production line of Dalian Lubricant Factory did not have an automatic rejection device, but only detected the aluminum foil while sealing, and sounded an alarm when the aluminum foil was missing, reminding the operator to manually remove the filled drum. However, since the production speed of our filling line is up to 3600 barrels/hour, manual removal in actual production not only poses a safety hazard, but also often results in the interruption of production or failure to remove the barrels without aluminum foil in time, resulting in the filling barrels without aluminum foil entering into the packing box, which has brought a series of negative impacts to our company, including:
② affect the quality of lubricant packaging appearance;
② affect the continuity and productivity of lubricant filling production;
③Cause the waste of oil products;
④ affect the lubricant shipment, storage, sales and reputation of Kunlun brand.
Therefore, in this high-speed, continuous automated production line can be detected on the barrel without aluminum foil timely rejection is particularly important. For this reason, the rejection device for non-aluminum foil filling barrels is designed and installed on the conveyor belt between the weighing induction aluminum foil sealing machine and the carton loading machine, which effectively solves the problem, ensures the tightness of sealing, improves the production efficiency, and is of great practicality and use value.
1 Comparison of process flow before design and after design
After filling and capping by the filling machine, the 4L oil filling drum enters the weighing induction area of the aluminum foil sealing machine for aluminum foil sealing, and then comes out and is detected by the aluminum foil detection sensor to detect whether there is aluminum foil in the cap or not, when aluminum foil is detected, there is no alarm in the machine, and the finished product after aluminum foil sealing enters into the next process to be packed in boxes. When the aluminum foil detection sensor detects no aluminum foil, the machine alarms, at this time, if the operator can not immediately take out the barrel, the barrel without aluminum foil continues to enter the crating area for crating.
1.2 The process flow of lubricating oil filling after designing
After filling and capping by the automatic filling machine, the 4L finished pail enters the weighing and sensing area of the aluminum foil sealing machine for aluminum foil sealing, and after coming out of the pail, the aluminum foil detecting sensor detects whether there is aluminum foil in the cap or not, when aluminum foil is detected, there is no alarm on the machine, the rejecting cylinder does not move, and the finished product after aluminum foil sealing enters the next process for case packing. When the aluminum foil detection sensor detects no aluminum foil, the machine alarms, the barrel detection sensor detects the barrel, the rejection cylinder moves and pushes the barrel to the rejection barrel storage area, at this time, if there is no operator, the barrel with no aluminum foil will not continue to enter the crating area for crating.
2 Design Principle
2.1 Working principle
After the filling barrel passes through the weighing and sensing aluminum foil sealing machine, when the aluminum foil detection sensor detects aluminum foil, the rejection cylinder does not move, and the barrel passes smoothly into the next process of carton loading; when no aluminum foil is detected, the machine carries out an audible alarm, and when the barrel detection sensor detects the barrel, it activates the weighing valve of the rejection cylinder, so that the rejection cylinder moves, pushes the barrel into the storage of the rejection barrel, and then the rejection cylinder is reset.
