Influence of tension force asymmetry on distribution of contact forces among the conveyor belt and idler rolls in pipe conveyor during transport of particulate solids

The paper discusses evaluation of machining solutions for oversized thin-walled robotic portal component for conveyance workplaces. The following portal CNC machining centers have been selected. Firstly, a FSGC 300 "portal type" portal was proposed, with a 50000 mm "X" axis and Heidenhain control system, the second portal was a DMU 340 portal with the maximum axis "X" of 6000 mm and Siemens Sinumerik control system and the last portal was the VF-10 / 40 one, with the maximum axis "X" of 3048 mm and Fanuc control system. Further, the method of fixing a thin-walled robotic portal is designed and individual options are evaluated for their economy. The CAM software application used for programming the production was SolidWorks.

“…Important aspects include transport outputs of equipment, weight emptying of equipment in time, possible dynamic or mechanical loading and material properties [14,15,16,17,18,19,20,21,22]. The use of the DEM alone does not necessarily have the correct predicative value without previous knowledge from measurements on investigated equipment.…”

The prerequisite for a modern approach to innovative procedures of the development of current or even newly created equipment for the transport of particulate materials is the utilization of simulation methods, such as the Discrete Element Method (DEM). This article focuses on the basic, or initial, validation of movement of material through the sample divider. The mechanical-physical properties of brown coal were measured. Based on these parameters the preliminary input values for EDEM Academic were selected, and a simulation of the dividing process was run. The key monitored parameters included density and friction coefficient. Experiments on a realistic model of the equipment were performed and assessed. The total weights of brown coal at the exit from the divider were determined for a specific speed of the divider. The aim of this task was to simulate the realistically determined weight division of the brown coal sample. The result from the DEM was compared with the results of measurement on a realistic model.

“…Currently, progressive technologies for thinwalled component production are gaining ground [3]. These include laser and waterjet machining [4].…”

The paper presents the general function, the division and the description of the main jig parts. It gives account of the basics and principles of a measuring jig structure using CAD applications. The main part delves into design of individual measurement jig options for measuring deformations of thin-walled robotic and conveyor components. Tension and stress analyses for each option have been performed. Subsequent to stress analysis, a suitable option was selected, with a description of its main parts, the production process and the necessary production equipment. Finally, the jig produced for the purpose of measuring deformation of thin-walled robotic and conveyor components is presented.
