Full textThe packaging of cylinder heads as spare parts for car engines is today done by hand in a company in Skövde that manufactures car engines. All cylinder heads are lifted by hand and placed inside cardboard boxes. The cardboard boxes are then sent to the retailer of spare parts. In order to improve the work situation from an ergonomic point of view and to minimize the risk of injury on both the cylinder heads and the employees, the company has ordered a lifting tool from the technical consulting company ÅF. The goal with this master thesis is to develop one or several models of lifting tool/tools that can lift as many different cylinder head models as possible. The lifting tool/tools are also going to be able to lift the cardboard box with the cylinder head inside. As starting point for the development of the lifting tool/tools, a literature study is made in the field of lifting tools. The literature study is divided into two parts; the first one includes general lifting tools on the market today. The second part analyses the different kind of lifting tools that the company already is using today. The literature study shows that there is a big variety in general lifting tools not only considering the external forces that is used to power the tools but also in which way the tools grips the objects. The study of the company’s existing lifting tools shows that it contains a big variety in different ways to grab both cylinder heads and engine blocks. To lift cylinder heads the company uses several kinds of principles, for example; lifting tools that grips with friction between lifting tool and the holes for the valve shafts. They also use lifting tools that grabs the cylinder heads by taking advantage of the cylinder head geometry. Basic concepts on how the cylinder head and the cardboard box can be lifted are developed by using a number of different design methods. Three basic concepts of lifting tools for lifting the cylinder head combined with two basic concepts on how the cardboard box can be lifted is presented to the company. One of the three basic concepts on how to lift the cylinder head is considered the best, based on its score in a concept score table. The best solution for how the cardboard box is to be lifted is not to lift it at all. Instead should the cardboard box be pushed away on a ball transfer table. Still, the company chooses another one of the basic concept for further development. Also the second solution on how to lift the cardboard box is chosen by the company. Due to that the cylinder heads geometries varies so much between the different models, two different lifting tools are developed. The construction of both of the tools is based on two aluminium frames, constructed by aluminium profiles. The two frames are joined together by linear motion bearings. The frames are lowered down over the cylinder head and then being pressed together by a pneumatic cylinder. This results in that the one of the two lifting tool is gripping the cylinder head with contact pressure and friction between the cylinder head and the aluminium cylinders on the lifting tool that have polyurethane vulcanised on its ends. The other lifting tool grips the cylinder head by using the cylinder heads geometry. The two lifting tools are both equipped with polyester bands with hooks mounted on its ends that fits in the premade handles on the cardboard box. This makes it possible to lift the cardboard box with a cylinder head inside of it. The result of this is two lifting tools, one that grips with pressure and friction and one that grips by mechanical locking based on the cylinder heads geometry. For the lifting tool that grips the cylinder head with pressure and friction a series of analyses is made using the Finite Elements method. The purpose with these analyses is to evaluate torque, stress and displacement of the lifting tool. From the results of these analyses in combination with some carefully considered assumptions, conclusions of the strength of mechanics for the lifting tool are made. This shows that all the included parts of the lifting tool; such as screw joints, linear motion bearings and aluminium profiles, have a factor of safety higher then 2 against plastic deformation. Based on obtained results from this thesis, advises on further development for the lifting tools are presented to ÅF.

Full textHandling and replacement of cylindrical surface treatment brushes for rolled sheet metal is currently done by hand at the company voestalpine Precision Strip AB in Munkfors. The workis described as time consuming, non-ergonomic and with some risk of personal injuries. The surface treatment brushes that are handled are sensitive to both forces and dirt on their outer jacket area and therefore require caution when handling. To improve the ergonomic circumstances and minimize the risk of personal injury while ensuring the handling of thebrush, the company has requested a lifting tool. The goal of the project is to develop a travers emounted lifting tool that can lift the brush directly from the delivery pallet and mount in the intended machine without risking the quality of the brush or exposing personnel to risks. The tool is designed to be CE-labeled after manufacturing. To get a clear picture of today's working methodology and to define problem areas for a brush change, a preliminary study is conducted. The result of this study, together with the wishes of the company, is summarized into a requirement specification that becomes a direct starting point for continued development of the design. The concepts and ideas that are developed are evaluated and presented to the project organization. Some of the solutions are considered to have potential for further development and are kept for further development. It should be mentioned that the further development of the lifting tool until its final construction is aproduct of partly my own solutions, and partly the viewpoints, ideas and aspects from other members of the project organization. The final construction of the traverse lifting tool meets the requirements formulated in the specification and is considered safe and easy to handle and with good chances of being CEmarked. The tool can lift the brushes from the delivery pallet, rotate and mount in and out of the machine without grabbing the outer casing area or otherwise risking the brush's functionality. The tool also completely eliminates the non-ergonomic movements that arise as a result of the manual handling of the brushes that occur today. It is noted that the final lifting tool has potential for improvement, thus it ́s provided suggestions for continued work and further development of the product.

Full textThe paper covers a product development project in which two students develops a tool for lifting heavy lorry batteries, for Scania’s repair shops. The problem is that the space above and on the sides of the batteries is very limited and that the batteries are so heavy that it is considered very ergonomically unfavorable to lift them manually. In order to study the ergonomic aspects, as well as other important aspects, that need to be consideredwhen developing the tool, the students have carried out a wide pre-study. This study has coveredeverything from benchmarking and observations to “safari” where the students themselves triedchanging the batteries a number of times. Numerous interviews and meetings have been held withemployees at Scania – most commonly in order to answer technical queries, but also to obtain feedbackon ideas and concepts.The students have also carried out a parallel project where a general “ergonomic checklist” for designing special tools has been developed. This has been done through deep studies of several ergonomic standards. The list has been revised multiple times after discussing it with the ergonomists at Scania andhas, together with other technical requirement, been used as a foundation for the specification ofrequirements.The ideation process has been carried out through brainstorming and continuous evaluations of theconcepts, using the specification of requirements. At some points matrices has been used to makedecisions between concepts, in order to show the requirements and how the concepts relate to them.The concept’s function and appropriateness have been evaluated through mockups, CAD-models and physical prototypes. It has been an iterative process where some concepts have been rejected when for example detailed sketches has been made. The prototype has also contributed to the discovery of some problems and restrictions.Finally, a practically functioning concept has been developed. The construction has been verified through tests and calculations. Manufacturing methods has been discussed for all components and Scania will receive a concept with full CAD-models and drawings. The product is in other words ready tobe manufactured, as soon as it has gone through minor adjustments and the CE-labeling procedure.

Full textDuring the second semester of 2013, product design engineering students Stefan Erlandsson and Louise Andersson have been involved in a project in cooperation with entrepreneur Lars Willebrand. The main objective of this project has been to develop a lifting tool for sheet materials. The lifting tool is one of four different products developed by Lars Willebrand. The line of products also includes an overhead crane, a slewing crane and a storage drawer for metal sheets, which are already fully developed and ready for production. The purpose of this lifting tool is to be used along with the storage drawer which means that is has to be optimised for lifting sheet materials from different heights. This means that the lifting tool has to be designed with regards to the users working postures. Human factors such as ergonomics have to be taken into account as well. The initial part of the project is a pre-study with focus on ergonomics and human factors. This pre-study included a study in relevant literature, contact with a manufacturing company and an analysis of the possible competitor’s lifting tools. The results from the pre-study have further been used to define the specification of requirements, which is the foundation for the concept development. The concept development has undergone a number of different phases. All of the lifting tool’s main functions were broken down and developed individually. The functions were as follows; adjustment of the suction cups, lifting from different heights and handling. The most suitable solution for each main function were chosen and assembled into one final concept. The final concept has been analysed and further developed in order to please the employer and the users of the lifting tool. Some details in the design have been changed in order to ease the manufacturing of the lifting tool. To ensure that the final concept matches the specification of requirements, strength calculations and FEM analysis have been made and anthropometrical measurements have been taken into account. The final chapters include a discussion and recommendations for further development of the lifting tool.

Full textGE Healthcare in Umeå manufactures equipment for hospitals and the pharmaceutical industry. In order to stay competitive they are constantly developing new and improved products. To fulfill internal and external health and safety regulations they must frequently develop lifting tools to transport products in the productions line.The newly developed product Crispo Rocker needs a new lifting device that can lift up and move the instrumentet from the assembly line to a testbench for the final testing. Since the instrumentet have some parts that must be attached to the underside of it, therefore the liftingdevice needs to be able to rotate the instrumentet during the lift in such a way that the final fitting can be done in a simple way.To complete the mision, several designconcepts have been developed and presented. From them, a liftingtool has been constructed that meets all requirements. For a tool to be put into use in the assembly area at GE, the equipment has to be CE-marked. Therfore a CE-survey has been conducted and several documens required to CE-mark a liftingtool has been produced.

Full textTo cut sheet metal into proper dimensions, for example shears can be used. They are available in many different variations where one is the guillotine shear. Rapido, manufactured by CIDAN Machinery, is a guillotine shear mainly targeted for small businesses which doesn´t cut regularly and with large size variations. This requires all manual material management which is stressful for the operator. The customers prefer the sheet metal to be available to be collected directly after the cut and at the same side of the machine as the input table. That’s why the sheet metal slides down on a plate called the sheet metal collector, located underneath the input table, in the current design. Because the input table has an ergonomic level of 85 cm, the sheet metal is collected from a much lower and uncomfortable level of 9 cm above the ground. The company wishes to approve the situation for the operator by offering an alternative sheet metal collector that makes the sheet metal available at higher level. The new solution shouldn´t raise the manufacturing cost more than 8%, to be profitable. A literature study is made to investigate solutions to similar problems and safety requirements. Concepts are generated and evaluated in an objective manner, for example by brainstorming and a concept selection matrix. One of the concepts is chosen for further development and design where standard components are top priority e.g. because of the reduction in environmental impact. Although standard components can´t solve for all functions and thus are unique parts designed. Some calculations are done analytically and by using the finite element method to verify the strength of the unique parts. In the resulting solution the operator can collect the sheet metal 37 cm above ground level and from a better position closer to the human body. The solution requires 15 new parts, of which 8 are standard components, and small modifications of 10 parts already in use. The increase of manufacturing cost is approximately 6 %. Pneumatics is used to lift the sheet metal which the operator only needs to activate, but the control function is not developed within the project. Even though the resulting solution doesn´t reach an ideal collecting height, of 80-110 cm, the company´s requirements is yet fulfilled. An additional function for ejecting the sheet metal is found to improve the ergonomics and is therefore included in the objectives for the project. Such function is included in the concept phase, but it isn´t further developed because of time constraints. Further investigations of CE-requirements need to be made before releasing the improved machine on the market since all necessary documents wasn´t available. More suggests of improvements is presented to the company, for example should silencing materials be used on the collector to reduce unpleasant noise.

Full textSandvik Materials Technology (SMT) i Sandviken tillverkar borrstänger till gruvindustrin. I en del av processen hanteras cylindriska ämnen, så kallade kuts. Idag hanteras kutsarna med hjälp av en robotstyrd magnet. För att öka robotcellens flexibilitet önskades ett verktyg för hantering av kutsar i icke-magnetiska material. Verktyget ska hantera kuts med och utan kärna. Kutsarna varierar i diametrar mellan 105-166 mm och i längd från 1330 mm till 1500 mm. Verktyget fick maximalt väga 36 kg. Utifrån en undersökning av befintliga lyftverktyg samt en specifikation av verktygets krav och förutsättningar kunde fyra gripfunktioner tas fram i ett idémöte. De framtagna funktionerna utvärderades i en Pugh-matris. Den funktion som ansågs vara mest lämplig för hantering av kuts utvecklades till åtta olika produktförslag i en morfologisk matris där ett produktförslag valdes att vidareutvecklas. Utformningen av verktyget bygger på dess funktion att gripa kutsen. Produkten delades upp i fyra huvudkomponenter för att underlätta konceptutvecklingen. Som komplement till de gjorda handberäkningarna genomfördes hållfasthetsanalyser med verktyget Ansys Workbench för att kontrollera hållfastheten i konstruktionen. En riskanalys utfördes på verktyget för att uppmärksamma de risker som en eventuell användare kan utsättas för under drift och vid underhåll. Arbetet resulterade i ett verktyg utformat för att hantera kuts från kortsidan med hjälp av utskjut. Utskjuten består av en lyftögla för hantering av kuts med kärna och en dubb för hantering av kuts utan kärna. Verktygets totala vikt blev 35 kg. En vidare utveckling av verktyget skulle kunna vara en viktoptimering. Ett sätt att minska vikten på verktyget vore att hantera både de magnetiska och icke- magnetiska kutsarna med samma verktyg. På så vis kan verktyget fästas direkt i roboten och snabbkopplingen från Schunk uteslutas. Med en kamera med tillräcklig noggrannhet att detektera kutsens position kan även styrplåten uteslutas ur konstruktionen.

Full textSammanfattningen av examensarbetet inom programmet Innovation och produktdesign (15hp). Tillhörande Akademin för innovation, design och teknik på Mälardalens Högskola i Eskilstuna. Arbetet utfördes under vårterminen 2019. Examensarbetet omfattar en utveckling i projektform, av ett designförslag till två konstruktioner. Konstruktionernas syfte är att möjliggöra byggprocesser för skapandet av rätvinkliga byggelement till ett byggsystem för återvinningsbara elementhus. Byggsystemet är en vidareutveckling av ett befintligt system, som används i fabriksmiljö som tillverkar prefabricerade småhus. Examensarbetet har utförts på uppdrag av företaget Husmuttern AB i Eskilstuna, som även står som skapare till byggsystemets vidareutveckling. Målsättningen med vidareutvecklingen av byggsystemet är att kunna prefabricera återvinningsbara småhus för både privatägande och uthyrning till offentlig verksamhet, så som tillfälliga skolbyggnader eller asylboenden. Skillnaden mot nuvarande byggsystem med samma målsättning är hur byggprocessen utformas i fabrik. Genom ett innovativt utnyttjande av styrande fixturer och animerade processbeskrivningar, elimineras behovet av både språkkunskaper samt byggteknisk utbildning hos utföraren. Resultatet tjänar två syften. Dels skapas arbetstillfällen för nyanlända eller personer som står långt från arbetsmarknaden tack vare att processtegen animeras utan krav på språkkunskaper och fixturer som eliminerar risker för alternativa utföranden. Dels kan byggnationen hålla hög takt för att möta en stor efterfrågan på bostadsmarknaden. Examensarbetes huvudfråga att besvara har varit: ”Hur bör konstruktionerna för att bistå lyft av väggelement samt produktion av hörnelement till byggsystemet utformas för att möta krav av säkerhet och ergonomi?” Arbetets metoder för att besvara huvudfrågan har omfattats av nedbrytning av huvudfrågan till delfrågor, fältarbete, praktiska- och elektroniska hållfasthetstester, diskussioner med företagets beslutsfattare, dialoger med områdesexperter, tidsdisposition i form av Gantt-schema, litteratur-studier samt beprövade metoder för värdering och generering av kundbehov och konceptlösningar. Arbetets resurser har omfattat 40 timmar/vecka av två studenters arbetsinsats under 20 arbetsveckor. Ytterligare resurser som använts är: dragprovsmaskin på Mälardalens Högskola i Eskilstuna, befintliga CAD filer för byggsystemet från företaget, CAD- och FEM program för konstruktions- och testarbete, tillgång till företagets lokaler samt fritt tillhandahållande av fysiskt byggmaterial. Arbetets resultat är denna rapport med presentation av två konstruktionsförslag i form av ett lyftredskap och en dockningsstation som genom praktiska och elektroniska tester, samt studerande av gällande regelverk förefaller klara kraven för CE märkning, vilket både är ett arbetsmiljökrav samt harmoniserar med företagets ambitioner om hög säkerhet och god ergonomi.

Full textThis report is a for the bachelor thesis in mechanical engineering at Karlstad University. The project was carried out at Falcken Forshaga outside Karlstad. Falcken Forshaga is a fresh started company that designs lifting tools for the concrete industry. There for they requested help to design an lifting tool for balancing of load. The purpose of this project was to design a tool throughout the product development process which could balance the load. To accomplice this the swedish machine directive had to be followed in order to allow CE-marking. To increase the knowledge about lifting tools a literature study was performed. The result of the study was compiled with the requests from Falcken Forshaga to shape the requirement specification. This document is the backbone for the continued designing of the lifting tool. All concepts developed during the concept generation phase has gone through an elimination matrix. In this matrix has all the concept has been weighed against the requirement specification. This was later presented to the company for decision about which concept to move forward with. When the design layout was done. Calculations and FEM- analysis were made on the critical details. Blueprints have also been made for every part that Falcken Forshaga are going to manufacture in their own workshop.

Full textDenna rapport behandlar ett examensarbete för högskoleingenjörprogrammet i maskinteknik på Karlstads universitet och omfattar 22.5 hp. Detta examensarbete är orienterat kring produktutvecklingsprocessen och varje fas i projektet baseras på teori och metoder som varit centralt till utbildningen. Uppdragsgivare för detta examensarbete har varit företaget Forshaga Svets Och Smide i Forshaga. Målet med projektet har varit att utveckla en provrigg för att kunna utföra CEmärkning på lyftverktyg. Lösningen skall vara robust och flexibel så att flera olika lyftverktygsvarianter kan CE-märkas i provriggen. I dagsläget använder sig Forshaga Svets Och Smide av traverser, svetsbord och en lyftögla fastskruvad i golvet. Planen är att med denna provrigg kunna överge dessa metoder och röra sig mot att använda provriggen som ett standardverktyg för att utföra sina CE-märkningar. Projektet resulterade i framtagningen av en provrigg som tillåter stor variation i lyftverktyg som kan CE-märkas och ökar den maximala belastnings och mätförmågan på lyftverktygen avsevärt och tillåter mer standardiserat arbete kring CE-märkning.
