The project was carried out with SwedSafe AB, engaged in hearing and manufacture of earplugs. Since the company is a world leader in the sale of these products, it is important that they keep a higher level of quality of these products.Production of earplugs is currently a automated manufacturing process that is divided into four conveyor belts and one of the conveyor belts is what will be affected in the project. The belt affected during this process is exposed to various elements such as filling, closing, fermentation and extraction of products. Because the belt gets dirty, degraded products and the work environment is affected. To increase the quality of products and improve the working environment requires an automatic cleaning process, which collects dirt from the belt.The aim of the project is to design a Machine that prevents the belt from becoming dirty, preserve molds clean and improve the working environment without disrupting production.

Reporting harvested and forwarded volumes are important for the forest industry as it provides information of the size of the stock and facilitates logistics. Figures from Holmen Skog show low reporting frequency. The purpose of this study is to investigate the reason and find suggestions for improvement. A total of 17 Machine operators were interviewed using a questionnaire combined with open questions. The results show that the majority of the Machine operators find it simple to use the reporting system, although, some of them reports that it doesn?t always work as supposed to.

The scarcity of qualified forest Machine operators as well as the increased competition for competent Machine operators among others from the mining industry in Norrland, were the reasons to investigate what attracts and what deters active and potential forest Machine operators to the occupation. An interview study was conducted among four groups with four persons in each group. The groups were students in year 1 and 3 respectively at a forestry school at upper secondary school level as well as employees of a forest company and employees of contractors. The majority of all respondents were of the opinion that their interests in Machines had been important for the choice of occupation. But for the active Machine operators both the interest in the forest and their interest for Machines have had importance for choosing this occupation.

Most companies have a bottleneck in their production, that is a constraining re-source. When the demand is higher than the capacity in the constraining resource it is impossible to produce the demanded output. This problem leads to delayed deliveries, unhappy customers and ultimately to decreased revenue. Bottlenecks therefore has a significant role in production and must be handled thereof.MW Power in Sävsjö, Sweden designs and manufactures water and steam boilers for the customer's unique needs. MW Power invested in a new plasma cutting ma-chine but the Machine has not reached the expected capacity.

The vision of this thesis was to create a concept that can be used as a base for aMachine construction. The purpose of this project was to use different methods todevelop a concept that on the best way meets the sat up requirements. This projecthas been divided into three stages/parts; principle, primary and the final solutionstage.This thesis has been conducted in collaboration with Västkustägg AB. It is aconstruction project designed to construct a Machine that will automatically putlabels on the egg packages. Västkust AB wanted to automate this process.

This report describes a synchronous Machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular Machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousMachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous Machine with its excitationsystems, e.g.

Metso Paper offers a front-running range of solutions and services for the pulp and paper industry. At the baling unit, design solutions are developed for manufacturing and handling of pulp bales. The Machines are continuously developed to satisfy customer needs. One big step in the development of the baling line was to remove hydraulics from the Machines and replace it with electrical motors and pneumatics. This was not done on the folding Machine which is still driven by mainly hydraulics.

This paper describes the process of building a Machine translation lexicon for use in the train and transport domain with the Machine translation system MATS. The lexicon will consist of a Swedish part, an English part and links between them and is derived from a Tradostranslation memory which is split into a training(90%) part and a testing(10%) part. The task is carried out mainly by using existing word linking software and recycling previous Machine translation lexicons from other domains. In order to do this, a method is developed where focus lies on automation by means of both existing and self developed software, in combination with manual interaction. The domain specific lexicon is then extended with a domain neutral core lexicon and a less domain neutral general lexicon.

Lars Höglund AB is one of Scandinavia?s most qualified manufacturers of sheet metal products and provides custom designed products of very detailed precision. One of the main methods of manufacturing is laser cutting. When Lars Höglund AB signed up a new customer, with high demands in tolerances for the products, Lars Höglund AB thought it would be necessary to know the capability of the laser cutting Machine. Also the process of how to retrieve this capability was interesting. The capability will be researched for the following elements: Cutting right angles in squares with a corner radius of 1 mmCutting corners which are not right angleCutting of circles with constant radius Measurements were made on 150 pieces of sheet metal details, which had been cut out by the Machine.  The data from the measurements where later used to study the capability.

We are getting smarter. Our knowledge of the world around us is increasing rapidly and our population spend a big portion of their time in school studying it. But art and craft are moving out to give room for more theoretical subjects. Today many of us can not even fix a torn shirt without help. We buy new ones, they are cheap enough.

Costs of maintenance on agriculture Machines is something that many farmers has a low knowledge of, it can depend on low interest or that the farmer don?t have enough time. To make it easier for the farmers they can use many computer programs which are available on the market. In this program they can calculate their costs of maintaince on their agriculture Machines, for example STANK and JTI Machine calculation program. Most of this program is using Svensson (1987) costs model whish was made in Sweden in the middle of 80 decade in a large study.

This report shows methods and workflow when exploring the potential to change Outotecs HCD Silver Electrolysis Machine to a module type. It?s done as an attempt to lower the workshop and installation costs and to give customer a more accurate prize directly. To do this a concept was produced which was set to a stress test. Additional objectives were to investigate freight and installation procedures, pneumatic connections and to calculate the difference in cost.Once the concept, a reinforced type of the original frame, was chosen stress tests in computer simulations were made and appropriate alterations were made.

The purpose with this bachelor thesis is to identify risks and insufficiencies concerning the production at WilloMaskin AB. The project is limited to only 4 Machines, where theories as ?OEE? (overall equipment efficacy) should be illuminated and analyzed. The theory of ?Single Minute Exchange of Die? is also presented.The method used in this project is mostly based on qualitative studies but also quantitative studies are presented.

This report was performed in order to evaluate a new technological measure and focuses generally on a heat pump system to a HWC-washing Machine. The client is Asko Appliances AB, a company well known for its environmentally friendly products. The goal of this study was to improve the energy efficiency of a washing Machine by combining a heat pump device to the heater of the wash water, in order to reduce the energy consumed for heating the water. Besides reducing the energy consumption in heating the water, the washing Machine was required to meet low noise and short operating time specifications. For that purpose, nine trials in three test series have been carried out.
