Independent thesis Basic level (university diploma), 15 credits / 22,5 HE credits
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:
An existing receiver for paper rolls has been redesigned and adapted into the new construction.
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.
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.
A guiding section has been developed, in which t-grids have been used to guide the transporter along the given elevator shaft.
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.
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.
