Nimetus Piiratud juurdepääs Tihendi paigalduspinkide tootmisvõimsuse väljaselgitamine ja maksimeerimine ETS NORD AS näitel(Tallinna Tehnikakõrgkool) Griezans, Janis; Kase, Andres; Lavin, JaakThe aim of the thesis was to indentify and maximize production capacity of seal mounting machnines on the example of ETS NORD AS. Seal mounthing machines are installing seals to NORDduct and NORDsmoke round product groups where product diameters are divided Also NORDduct and NORDsmokefrom 80mm to 1600mm. round groups are divided into prodcuts with angles of 30, 45, 60 and 90 degrees. There are total amount of seal mounting machines in the Production1 department 16. The base for thesis was all 16 seal mounting machines an ETS NORD AS Tootmine1 department. d the tools intended for their adjustment in This thesis first examines was mapping their tools which gave information what options is ETS NORD AS using the 16 machines and today machines. Once the machi with seal mounting nes were mapped, an interview was conducted with the company’s machine mechanics to find out which tools were suitable for setting up the machines for any other diameter in addition to what is being configured today. As a result the diameter capacity of th machines installing e 13 seal mounting seals on the products increased and the actual capabilites of the sealing machines were known. In a second stage was found out how many tool sets are availa a result was known what is the maxi ble for each diameter. As mum amount of working centers for every diameter when every seal mounting machine was taken into account. In the third stage was found out the effective working time base of the sealing machines and the cost of the sealing machine process for each diameter . In the final part was to calculate production capacity. Production capacity was calculated using an machine efficient working time, process cost per seal and maximum working centers per shift. At the beginning, production capacity was found out for each diameter and with only one working center in one shift. Later production capacity was found out for each diameter when using all possible seal mounting machines in EST NORD AS Tootmine1 department. After production capacity was found out the author compare d the existing production capacity with the new procution capacity. On average considering every seal mounting machine the production capacity increased by 83%. Diameters in the range of 100 poss 200mm, where production volume is highe st, received 13 new ible working centers. The largest increase in production capacity was in the diameter of 200mm where the production capacity increased by 166%. The production capacity of 400 - 600mm diameters increased by 100%. There were no changes in the production capa city of the sealing installion of 80mm, 250mm and 315mm products. Highes volume products are in 100mm and 125mm diameter and their prodcution capacity to install seals in one shift is 9600 seals if every resource is used effectively. Proposals to ETS NORD AS would be to investigate what are the most effective loads for seal mounting machines with new production capacity. They should draw up a plan according to demand how much the benches should be loaded with diffrent diameters. Second proposal is to find out whether the investment of an 80mm diameter tool set would be expedient becouse if the additional set were available, ETS NORD would be able to install seals on 80mm diameter products on two diffrent benches (1070 and 1662) at the same time. Production capacity at 80mm diameter products would increase 100%. A third proposal would be to perform an analysis to cut the heigh of the sealing bench 1159. If the height of the 1159 bench would be shorter then there could fit in 250 diameter tools. After cutting the heigh, it would be possible to install seals to 250 315mm 315mm diameter products on two diffrent machines (1159, 3158) at the same time instead of 1 machine.
