The research about a design of prototype automatic pineapple sorting has been done with a belt conveyor system using a Blue Pill STM32F103C8T6 microcontroller. This research was conducted to create a prototype that can sort pineapples based on maturity level by classified unripe, ripe, and fully ripe. Sorting pineapple against the pineapple ripeness classification was carried out by a simulation process using serial data of index maturity sent from the PC monitor serial to microcontroller via serial communication. The serial data sent in character format was an integer 1; 2; 3; 4; 5; 6; and 7. The conveyor using a chain with gear transmission system and a DC motor as a drive. The results showed that the instument is capable of carrying a maximum load of pineapple fruit of 1.0 kg with a transport speed of 27,98 cm/s and can perform pineapple ripeness sorting with an accuracy more than 90%.

Conveyor Roller

Belt conveyor is widely used in mine, coal, chemical industry, ports, and power plants. It’s one of the significant devices of continuous conveyor. Roller is a crucial component with regard to belt conveyor system, which supports belts and cargos. In the design of the belt conveyor, a third of major consumption went into rollers. The critical consideration for minimum cost, which including operating, manufacturing, maintenance expenditure, is the selection of idler spacing. For optimization purposes, the optimum pitch between the rollers is regard as more decisive variable, especially for minimizing consumption and reducing rollers’ number than other various factors. This paper discusses the idler spacing to proceed from original technical first, secondly analyzes the effective factors in detail and then deduces rational arrangement mathematical expressions of idler spacing. Simultaneously, combining with the corresponding parameter, we draw up the hierarchical layout figure of idler spacing distribution through the calculation expression. It’s the optimal option of idler spacing that providing an outstanding reference in the actual production.

The primary function of idler rolls in a belt conveyor system is to support the conveyor belt along its length. Predicting the cumulative resistance of idler rolls is vitally important in calculating the belt tension and therefore power requirements of a system, particularly on long overland conveyors where there are typically more than one thousand idler rolls per kilometer of belt. The rotating resistance occurs due to the friction of the rolling elements in the bearings, the viscous drag of the lubricant, and the friction of the contact lip seals. This paper provides theoretical methods to calculate each component of the rotating resistance and describes an apparatus designed to measure this resistance force under simulated operating conditions.
