Field of the Invention:
The present invention relates to Smart Multicolour Ink Dispensing Machine for Markers. More specifically, the present invention relates to a smart machine for dispensing different color ink into the marker based on the choice of color and marker size by user in an automated way. It is reducing the need of purchasing multiple small refilling bottles, which leads to reducing plastic waste; and also reducing the spillage of ink, which leads to reduced health hazards of ink, no staining on cloths and surface, and no dirty hands.
Background of the Invention:
Marker pens use a felt tip and water-based or alcohol-based ink to produce a wide, intense line. They are commonly used for marking, highlighting, drawing, and are available in various colors and tip sizes.
Whiteboard marker pens are designed for use on whiteboards or other non-porous surfaces. They use water-based ink that is easily erasable and available in various colors. These pens are commonly used in offices, classrooms, and other settings for presentations and visual aids. The whiteboard marker pen works by pressing the tip against the whiteboard surface, which allows the ink to flow out and onto the board. The water-based ink dries quickly and provides a bright, vivid line that can be easily seen from a distance. The ink is formulated to be erasable and can be easily wiped off the whiteboard surface with a cloth or eraser.
By refilling a whiteboard marker pen, we can extend its life and save money compared to buying a new pen. Overfilling a whiteboard marker pen can cause several problems, including spillage of ink on hands, leaking, staining. This can be messy and difficult to clean up. Overfilling can also cause the marker to leak and not work properly, making it difficult to write with the marker. If the ink spills onto clothing or other surfaces, it can be difficult to remove the stain. The ink used in whiteboard markers is not intended for skin contact, and exposure to the ink can cause skin irritation or other health concerns.
The ink used in whiteboard markers can pose certain health problems. Exposure to ink can cause skin irritation or other skin reactions, especially in people with sensitive skin. Some whiteboard markers contain volatile organic compounds (VOCs) that can be released into the air and inhaled, leading to respiratory problems. Some whiteboard markers contain toxic ingredients, such as xylene or benzene, which can be harmful if ingested or inhaled. Some individuals may experience an allergic reaction to the ink used in whiteboard markers.
Using a large plastic container of ink can be more cost-effective than using multiple small refill plastic bottles of ink. The cost per unit of ink is generally lower when you buy it in bulk. Additionally, a large container of ink can last a long time, reducing the frequency of ink purchases. You don't have to worry about running out of ink mid-meeting or mid-class. Using a large plastic container of ink can be more environmentally friendly than using multiple small refill plastic bottles of ink. A large container generates less waste than many small bottles, reducing the amount of plastic that ends up in landfills or oceans.
Hence, there is a requirement to develop a smart electronically controlled sensor equipped machine which allow the user to refill the marker with the choice of color ink effortlessly in less time, reducing the spillage and wastage of ink. The need to purchase a small ink refilling bottle can be avoided with the present invention, which use the large ink container thus helping to reduce plastic waste.

The main objective of the present invention is to develop an electronically controlled sensor equipped multicolour ink dispensing machine which allow the user to refill the marker with the choice of color ink.

Another objective of the present invention is to develop an ink refilling station that allows the user to refill the marker with the chosen color ink in an automated way with minimal human involvement.

Yet another objective of the present invention is to effectively dispense the ink to the marker, reducing the spillage and wastage of ink.

Yet another objective of the present invention is to prevent leakage of ink which help to reduce the staining of clothes and surface.

Yet another objective of the present invention is to refill the marker effortlessly which help the user to refill the ink in less time.

Yet another objective of the present invention is to prevent the exposure of ink to skin and thus safe for health and safety matters.

Yet another objective of the present invention is to eliminate the purchase requirement of small ink refilling bottles of multicolor with the large ink containers, which in turn helps in reducing the plastic waste.

Summary of the Invention:

The present invention is a smart ink refilling station that allows the person to refill the marker with the chosen color ink in an automated way with minimal human involvement, preventing ink waste and spillage when refilling. The ink dispensing machine is equipped with multiple ink containers, pump, electronic control valves, IR sensors, ultrasonic sensors, nozzle, microcontroller, battery and charger. On the basis of user input from touch screen display, the microcontroller will send the command to the particular electronic control valve and pump to dispense the ink through the nozzle to the marker. Various sensors are interfaced for the detection of the movement in front of the machine, detection of marker under the nozzle, and measurement of ink level in the container.

A pump is used to transfer ink from the ink container to the nozzle via pipe; in between, an electronic control valve is installed with each ink container to determine which ink should be replenished based on the user's preference.
