An Apparatus For Dispensing A Rolled Material

23.03.2015

Researchers from the Faculty of Mechanical Engineering, University Teknologi MARA, Malaysia, have designed and built a low cost apparatus to enable workers to roll out fibre sheets from a fibre roll onto a table which would make all cutting task easy. The apparatus design is ergonomical and reduces dust contaminating the work environment.

The conventional preparation of fibre sheets from fibre rolls has been a problem in many factories in Malaysia, as workers manually unroll the fibre rolls and perform the cutting task on the floor leading to Work-related Musculoskeletal Disorders (WMSDs) such as low back pain and leg pain.

Other Occupational Health and Safety (OHS) problems such as tiredness and dizziness (as a result of constant squatting and back bending), sore throat, nose irritation and eye itchiness (due to fibre dust spreading around) are among the major complaints.

A new low cost apparatus was built to enable a worker to roll out fibre sheet from a fibre roll onto a table, as such, all cutting tasks can be conducted ergonomically at a comfortable working height with reduced dust contaminating the work environment. The apparatus can also reduce the inhalation of hazardous dust or fine particles by collecting them from the rolled material.

The embodiment of the invention comprises a frame which is a semi-circular construct supported on legs. There are three parallel rollers extended axially to the construct, two to support the rolled material while one to ease the rolling function at the dispensing end of the construct. The rolled material can then be conveniently pulled (by the leading edge) to unleash its sheet without coming into contact with any sharp edges which pose potential risks of damaging the dispensed length of the material.

The surface of the dispensed material is therefore substantially protected from any scratches, tear or any other forms of damage. The rollers are mounted on roller bearings on both sides of the construct where vertical rings are in place. The bearings allow forward and backward rotation of rollers with ease. The spacing between the support rollers is subtly arranged to ensure that the rolled material is well supported even if it reduces in size gradually after each round of dispensing action.

The two vertical rings specifically installed beside both sides of the construct are to retain the fibre roll within the central position. A dust collector having a configuration conforming to the semi-circular construct is located below the rollers to collect dust being shed from the rolled material and prevent it from falling out of the construct uncontrollably causing airborne dust transmission. Dust can thus be swept and collected from either end of the dust collector.

The rolled material which can be coreless, such as a fibreglass insulation blanket, a mineral wool roll, a natural fibre roll, a synthetic fibre roll or a plastic fibre roll. Alternatively, cored rolled material (with a centre-core) which can be a tissue roll, a kitchen towel roll, rolled foam material or rolled plastic bags, all of which can be unrolled and dispensed without the need of an axle.

An ergonomics study was conducted in a workplace where the cutting of glass fibre was carried out on the floor. The new invention was deployed to dispense glass fibre sheet from its roll to a matching work table, where the cutting task was carried out comfortably on table top. After 3 months of intervention, a tremendous reduction of workers' complaints and a significant productivity increase of 312% were recorded. A statistical paired-samples t-test confirmed the effectiveness of the new invention.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
