Rotab Rostfria Transportörer AB tillverkar och utvecklar material- och godshanteringsutrustning. Företaget levererar även kompletta materialhanteringslösningar i form av godshanteringsanläggningar som ofta består av transportband och paketeringsutrustning. Examensarbetets mål är att utveckla en vertikaltransportör som ska transportera gods mellan två transportband belägna på olika höjder, transporten ska kunna varieras mellan 1000 - 3000 mm. Transportören ska undvika de två stora nackdelarna som återfinns hos konkurrerande produkter, att de är utrymmeskrävande eller att de använder sig av synkroniserade kedjor. Vertikaltransportören baseras på en konceptidé som tagits fram på företaget. Denna konceptidé utvecklas till en prototyp med hjälp av metoder för produktutveckling. Produktutvecklingsprocessen delas upp i olika faser som inleds med en problemdefinierande fas. Därefter definieras produktens önskade funktioner, detta används till att utveckla ett flertal koncept. Ett av koncepten väljs ut för vidareutveckling. Utifrån det valda konceptet konstrueras en prototyp som används för underlag till en utvärdering. Vid examensarbetets slut har en digital prototyp konstruerats i CAD-programmet (Computer Aided Design) SpaceClaim. Konstruktionen är dimensionerad för att hantera gods med dimensionerna ( längd x bredd x höjd) 400x400x300 mm samt en godsvikt upp till 20 kg. Den drivs av en elektrisk kuggväxelmotor med 0,55 kW:s effekt. Den lägsta möjliga hämthöjden är 800 mm över golvet. Prototypens högsta avlämningshöjd är 3490 mm över golvet, detta kan dock ökas vid behov. Prototypen klarar av 39,5 transporter i minuten. Prototypen är ett bra val för vertikala transporter av gods i den storleksordning som den är dimensionerad för att hantera. Dock är den sämre på att hantera gods i mindre storleksordning. Prototypen bör tillämpas då godset behöver förflyttas vertikalt och endast ta en kort horisontell sträcka i anspråk. I de fall där, den långa horisontella sträcka som krävs av, en vinkeltransportör ryms bör istället en sådan tillämpas. Då vinkeltransportören har en högre transportkapacitet, simplare konstruktion och lägre kostnad. / Rotab Rostfria Transportörer AB manufactures and develops equipment for handling of materials and goods. The company also provides complete solutions for the handling of materials and goods, these solutions often consist of conveyors and equipment for packaging. The goal of the thesis is to design a vertical conveyor which is intended to transport goods from one conveyor to second conveyor located at another elevation. The vertical transportation must be variable between 1000 and 3000 mm above the floor. The conveyor must avoid the two major disadvantages that are common amongst competing products, these are often space consuming and/or use synchronized chains. The vertical conveyor is based on a conceptual idea developed at the company. In the thesis work, the idea is developed into a prototype with the aid of product development methodology. The product development process is divided into several phases, starting with a problem defining phase. After the first phase the required features are defined, the features are used as support for the development of several concepts. One of the concepts is chosen for further development. The chosen concept is the base for the design of the prototype. The finished prototype is evaluated. At the end of the thesis work a digital prototype has been designed using the CAD (Computer Aided Design) software SpaceClaim. The prototype is designed to handle goods with the following dimensions ( length x width x height) 400x400x300 mm and also with a mass up to 20 kg. It is powered by an electrical gear motor with a power output of 0.55 kW. The lowest possible pickup height is 800 mm above the floor level. The highest unloading height for the prototype is 3490 mm above floor level; it is possible to increase the unloading height in order to achieve 3000 mm. The rate of transports is 39.5 transports every minute. The prototype is a good choice for vertical transportation of goods in the same dimensions as described above. It is not as well suited for transportation of smaller goods. The prototype should be used when the vertical transportation is required to be achieved in a short horizontal distance. If the available horizontal space is sufficient for an angled conveyor to be used, a conveyor of that type should be used instead. Since an angled conveyor has higher capacity for transportation, an simpler design and is cheaper than the prototype.

This project includes a thesis performed at Karlstad University in spring 2013. The thesis is included in the mechanical engineering program and contains 22.5 university points, which is equivalent to 480 hours of work including self-study.   This work has implemented by the student Luiz Ferreira in cooperation with the firm Camatec Industriteknik AB in Karlstad.   The purpose of this project has been that the company Camatec wants to offer their customers a standard vertical transporter. This transporter must be able to transport paper rolls, which can weigh up to 5 tons, between two floors. The objective with this project has been to prepare a complete set of drawings for a vertical transporter and a price estimate of all its components. This transporter must fit into a given elevator shaft but also be able to adapt into different dimensions.   A vertical transporter has been developed with help of different methods including 3D-modeling, Finite Element Method and strength calculations.   The total development of the transporter has been divided into several areas of constructions: Receiver for paper rolls An existing receiver for paper rolls has been redesigned and adapted into the new construction. Frame A frame has been developed including I-beams, flat bars and hollow structural sections which have been connected with welding and bolts to hold the receiver. Mechanism A mechanism of shaft and bearings, which allow the receiver to rotate so the paper rolls can relief in a facility way, has been designed. Guiding A guiding section has been developed, in which t-grids have been used to guide the transporter along the given elevator shaft. Vibration damper Two ANB 100 vibration dampers with a hardness of 70 Shore have been used to suppress one side of the receiver so it can rotate. Hoist An appropriate rope hoist for this transporter has been discussed with the firm ABUS Kransystem AB in Karlstad. This hoist carries almost the entire transporter.   Standard components are used through the entire project and these have been estimated at an amount of about 306 000 Swedish crowns, where prices for the existing solution of receiver, processing and installation are not included.
