Label dispensers and label applicators are machines built to simplify the process of removing a label from its liner or backing tape. Some are bench-top for dispensing the labels while others include the application of the label to the item (such as a package). Unlike label printer applicators, they dispense preprinted labels.

Contents

Label dispensers are generally intended to dispense a label to an operator who manually applies the label to the package. They are designed with varying sizes and features which are often specific to the type of label they can dispense and to the degree of automation desired.

Label applicators are usually part of a larger packaging line. They receive the package from a previous automation stage, apply the label, and feed the package to the next stage in the packaging line.

Use

Many everyday items have stick-on labels, which were either applied by a machine or by hand, and most likely were peeled from the backing paper using some sort of label dispenser. Some of the more common applications are bulk mailing, manufacturing, packaging, food and beverage, fast food, and photo labs.

Manual label dispenser

Patents on manual label dispensers go back to the 1920s. They are designed for light-duty use. They are operated by hand and are not automated, but still assist in the process of removing labels from their liners. Many manual label dispensers can dispense multiple rolls at once. Operation is performed by pulling the liner/backing paper around a plate or bar which causes the label to peel away from the backing paper. This happens because the backing paper is usually thinner than the label itself and is also underneath. When the liner is forced around a tight radius the label lifts away and protrudes through the front or top of the dispenser.

Semi-automatic label dispenser

Electric semi-automatic label dispensers were first patented in the early 1970s. They were originally designed for multiple-row address labels for bulk mailing houses. On average a good mailing house employee could apply approximately 500 labels per hour to envelopes. The label dispenser increased this to over 2,000 per hour. These dispensers advance individual or multiple-row labels and remove them from their lining similar to a manual dispenser, but instead of manually pulling on the liner, label advancement occurs when a trigger on the dispenser detects the absence of a label, such as when the operator removes the label. The sensor then closes the circuit and engages the motor, dispensing the next label until the sensor once again detects the label which opens the circuit. The first electric dispenser was designed with the limit switch on the left of a 16" wide machine. 4-up multiple-row labels were loaded into the machine and once activated would advance one row of labels. The operator would take the labels from right to left, so that when the leftmost label was taken, the next row advanced, automatically providing a constant supply of labels to apply. The labels are also peeled without the natural curl that will happen when pulled from the backing paper with fingers. Also, only one hand was needed to take the label, the other hand could be used to move the material the label was being applied to.

Semi-automatic label dispensers are often built to withstand industrial conditions.

Label applicators

Label applicators are fully automated and can range from simple slower speed models to large machines capable of applying hundreds or even thousands of labels per minute. [1]

Applicators advance the label stock over the peeler plate until a portion of the label, called the "flag," is extended into the path of the oncoming package. When the package engages the label flag, the label web is advanced to match the speed of the package and label is either tamped or wiped on to assure adhesion. Proper alignment of the label on the package depends on sensors that sense the location/orientation of the package and label sensors that detect the location of the label edge. Package sensors can be a variety of Position sensors, often optical sensors or Ultrasonic sensors. Label sensors are usually Photoelectric sensors because they are inexpensive. But clear labels cannot be detected by photoelectric sensors. Capacitive and ultrasonic technologies are used for clear label detection. [2] [3]

Flexography is a form of printing process which utilizes a flexible relief plate. It is essentially a modern version of letterpress, evolved with high speed rotary functionality, which can be used for printing on almost any type of substrate, including plastic, metallic films, cellophane, and paper. It is widely used for printing on the non-porous substrates required for various types of food packaging.

Packaging is the science, art and technology of enclosing or protecting products for distribution, storage, sale, and use. Packaging also refers to the process of designing, evaluating, and producing packages. Packaging can be described as a coordinated system of preparing goods for transport, warehousing, logistics, sale, and end use. Packaging contains, protects, preserves, transports, informs, and sells. In many countries it is fully integrated into government, business, institutional, industrial, and personal use.

A water dispenser, known as water cooler, is a machine that dispenses and often also cools or heats up water with a refrigeration unit. It is commonly located near the restroom due to closer access to plumbing. A drain line is also provided from the water cooler into the sewer system.

The term dispenser typically imply a machine or container which is designed to release a specific amount of its content, usually liquids or powders/fine granular materials.

Photodetectors, also called photosensors, are sensors of light or other electromagnetic radiation. There is a wide variety of photodetectors which may be classified by mechanism of detection, such as photoelectric or photochemical effects, or by various performance metrics, such as spectral response. Semiconductor-based photodetectors typically photo detector have a p–n junction that converts light photons into current. The absorbed photons make electron–hole pairs in the depletion region. Photodiodes and photo transistors are a few examples of photo detectors. Solar cells convert some of the light energy absorbed into electrical energy.
