This diploma thesis deals with the design of a full pallet storage stacker using the FIFO method. The first part of the thesis contains a research analysis of similar competitive solutions. This is followed by a description of the created conceptual design of the storage stacker. The design includes the choice of speeds and accelerations of stacker movements, which are necessary for the calculations of the tilting, lifting and traveling mechanism. Another part of the thesis is the strength check of the lifting carriage frame. The attachment consists of the drawing documentation of the designed device.

The report is about reducing the Eigen weight of a reach stacker in order to obtain decreased fuel consumption. The detail the product development treats is the telescopic boom. By using steel of higher strength the dimension can be decreased, which in turn results in a reduced weight. Suitable steel for the application might be the high strength structural steel of designation S690QL. With support of calculations and CAD simulations the possible weight reduction is assumed to amount to 28%.

The purpose has been to analyze a modelling process based on the finite element method (FEM), for a powered stacker truck of the model SPE 140 TX HILO. It was analyzed how such a model should be designed in order to perform stability analyses. This was done by analyzing which of the trucks components that were relevant from a stability perspective. These components were analyzed in order to figure out which modelling approach that was best suited to model the components in a FEM-software. The result of these analyses is a modelling methodology describing which approach that should be used during the entire modelling process of a FEM-model consisting of an entire truck.

In these days, on over the world, we ca find a huge CNC centres which are more and more often completely automatized. There is no necessity of human intervention to change or stock the machining tools. All these operations are made thanks of robots and manipulators to economize time and money. Target of this these is conception of the mobile storage stacker which can be made and then transported to the place of usage in a 40ft sea container. After transportation the stacker is completelly reade to use. Thanks of this concept, we gain universal storage stacker for differents conditions without necessity of new concepts and and solutions for each CNC centre.

The Fourth Industrial Revolution is reshaping the manufacturing industry with the emergence of interconnectivity, smart automation, and cyber-physical systems. A popular example of cyber-physical systems is the digital twin or digital model, which both create a virtual (cyber) representation of a system. This virtual representation enables the simulation of manufacturing processes and thereby allows facilitating the understanding, optimization, planning, and prediction of the behavior of the manufacturing chain without interfering with the real system. Mining is an energy-intensive industry that can benefit from process optimization, improved production planning, and more precise material quality predictions. To accomplish this, the mined material must be tracked from its source through the mining process chain to its final destination. Because a continuous material flow cannot be tracked in the same way as a manufacturing piece can, a digital twin or model is a suitable solution for material tracking. This project is part of the effort to develop a digital model of the mining process chain and focuses on a specific mining process, the bucket-wheel stacker. A stacker is a huge machine that builds stockpiles with arriving bulk material. The digital model of the stacker must predict the stacker’s behavior in terms of spatial and temporal changes the stacker applies to the material flow. A carrier-portion model is used to digitize the material flow into discrete material portions which are transported by virtual carriers in the digital model. With the help of the forward kinematics method, the digital model utilizes a parameterized robotic model of the stacker to describe the spatial aspect of the stacker. Temporal changes are represented with simple speed-distance-duration calculations. The digital model is implemented in Java programming code and is implemented into an existing material tracking program. The results of the digital model validation show an adequate spatial accuracy of ±0.1 [m] compared to simulated and calculated values. The temporal accuracy is guaranteed to be lower than ±1 [s] compared to calculated values for certain implementation parameters. This project demonstrates that a lightweight digital stacker model for material tracking is feasible and has the potential to be expanded into a digital twin. / Den fjärde industriella revolutionen håller på att omforma tillverknings-industrin i och med framväxten av sammankoppling, smart automation och cyberfysiska system. Ett populärt exempel på cyberfysiska system är den digitala tvillingen eller digitala modellen, som skapar en virtuell (cyber) representation av ett system. Denna virtuella representation möjliggör simulering av tillverkningsprocesser och underlättar därmed förståelse, optimering, planering och förutsägelse av tillverkningskedjans beteende utan att störa det verkliga systemet. Gruvdrift är en energiintensiv industri som kan dra nytta av processoptimering, förbättrad produktionsplanering och mer exakta förutsägelser av materialkvaliteten. För att åstadkomma detta måste det utvunna materialet spåras från sin källa genom gruvprocessens kedja till sin slutdestination. Eftersom ett kontinuerligt materialflöde inte kan spåras på samma sätt som ett tillverkningsstycke, är en digital tvilling eller modell en lämplig lösning för materialspårning. Det här projektet är en del av arbetet med att utveckla en digital modell av gruvprocesskedjan, och fokuserar på en specifik gruvprocess, skovelhjulsstaplare. En staplare är en enorm maskin som bygger upp högar med ankommande bulk material. Den digitala modellen av staplaren måste förutsäga staplarens beteende i termer av rumsliga och tidsmässiga förändringar som staplaren tillämpar på materialflödet. En bärar-portionsmodell används för att digitalisera materialflödet i diskreta materialportioner som transporteras av virtuella bärare i den digitala modellen. Med hjälp av metoden forward kinematics använder den digitala modellen en parametriserad robotmodell av staplaren för att beskriva den rumsliga aspekten av staplaren. Temporala förändringar representeras med enkla beräkningar av hastighet, avstånd och varaktighet. Den digitala modellen är implementerad i Java-programmeringskod och är integrerad i ett befintligt materialspårningsprogram. Resultaten av den digital modellens valideringen visar en rumslig noggrannhet på ±0.1 [m] jämfört med simulerade och beräknade värden. Den tidsmässiga noggrannheten garanteras vara lägre än ±1 [s] jämfört med beräknade värden för vissa implementeringsparametrar. Projektet visar att en lightweight digital staplingsmodell för materialspårning är genomförbar och har potential att utökas till en digital tvilling.

The nature of how an Automatic Storage & Retrieval System stacker crane moves through the aisle, between picking and storing operations, is analyzed through a simulation model. A continuous SLAM model simulates the performance of a single aisle Automatic Storage & Retrieval System stacker crane under various control conditions. Crane speed, acceleration rate, job arrival rate, and discrete or continuous interrupt sensing are the variables examined within the model. The performance level of the system is observed while altering the control. / M.S.

In recent years there has been a trend towards large-scale logistics for individual members of the public, such as ride-sharing services and drone package delivery. Efficient coordination of pickups and deliveries is essential in order to keep costs and wait times down. In this thesis we present these types of problems in a more general framework, expanding applicability of our discussion to an even wider domain of problems. We present fast new al- gorithms with supporting theoretical and experimental analysis, providing certain guarantees about how close our algorithms compare to a theoretically optimal approach. / Master of Science / In recent years there has been a trend towards large-scale logistics for individual members of the public, such as ride-sharing services and drone package delivery.
