    Opis:
    Pipe conveyors represent a continuous transport system that is difficult to obtain real operating data from in terms of operational characteristics’ research. That is why the research of these conveyors is mainly supported with the data from special, static testing rigs. However, the measurements do not provide corresponding operating results and can differ from actual operating conditions. That is why, a dynamic testing rig was designed for the research which also represents the smallest pipe conveyor worldwide. The article describes options of conveyor belts and pipe belt conveyor components examination with the use of static and dynamic testing rig, and researches a new design and implementation of a dynamic testing rig - the smallest fully functional pipe belt conveyor in the world with a length of 11 m and belt width of 0.6 m. The said testing device can provide data obtained during dynamic operation of the pipe conveyor, which compared with a static rig increases the accuracy and value of obtained data and results.

    Opis:
    Finite element methods are used in many disciplines for the development of products, typically in mechanical engineering (for example in automotive industry, biomechanics, etc.). Some modern programs of finite element methods have specific tools (electromagnetic, fluid and structural simulations). The finite elements methods allow detailed presentation of structures by bending or torsion, complete design, testing and optimization before the prototype production. The aims of this paper were model a conveyor belt passage with a driving drum. The model was created in Abaqus CAE program. The created model presented data about forces, pressures, and deformation of the conveyor belt.

    Opis:
    Pipe conveyors make up important elements of ecological transport systems. They ensure the material is transported in the conveyor belt coiled to the shape of a pipe. Various stresses impact their most important component - the conveyor belt - straining it in both, the longitudinal and the transverse direction. This phenomenon arises in connection with the shape of the conveyor route of the pipe conveyor, the width and thickness of the conveyor belt, the volume of the material conveyed, and the like. In recent years, more and more authors have been researching contact dependencies of the normal forces acting on the idler rolls located in idler housings. Their task is to design such structure of a conveyor belt that will put the least strain on the idler rolls, thus significantly reducing the power required to ensure the movement of the pipe conveyor. In this way, greater efficiency of eco-friendly transport will be achieved. Following experimental research, the paper describes a regression model of dependencies of normal contact forces on tension forces required, as per individual idler rolls in idler housing.

    Opis:
    This paper presents the use of new modern methods for the research of movement of material on a belt conveyor. One of the innovative methods is Particle Image Velocimetry (PIV), which was used to scan and assess the two-dimensional vector field of speed of particles on the belt conveyor. Outputs from PIV were compared to simulations of the same transport process. These simulations were performed using the Discrete Element Method (DEM). Four transport speeds of material were assessed for a real and simulative belt conveyor model. Software tracking of particle movement was used to determine and compare the trajectories of paths of particles leaving the belt conveyor drum. Validation of the DEM simulation of material movement over a belt conveyor drum using PIV provided acceptable results in the area of particle speed fields. Comparison of the particle path trajectory corresponds to the preliminary hypothesis which leads to calibration of the DEM simulation. The results and assessment of this paper were created based on validation.

    Opis:
    Implementation of modern handling facilities contributes to the quality performance of each business subject. Nowadays, mechanization and automation of processes associated with the handling of shipments finds an important place especially under the conditions of the postal and logistics sector, which is growing due to ecommerce. The method of allocating large mechanization and automation, the performance and other characteristics significantly influence the realization of processing shipments in relation to the quality of service but also labour intensity and human performance. The paper deals with the issue of the appropriate location of the conveyor within the space available depot, as well as calculation of performance and technical parameters and multi-criteria evaluation for an appropriate choice of the conveyor. Such factors as energy performance, noise, safety at work, location and so on, were considered.
