Industrial Labeling Machines
Labeling machines dispense and apply labels on containers like bottles, vials, and ampoules. They also print information on them such as the date of production, expiry, and batch number.
They can work simultaneously on several shapes, sizes, and types of containers. These machines are easy to operate and offer optimum results.
Printing
Labeling Machines allow for the printing of text or bar codes on labels. They can also be used to dispense labels on items and containers as they move along conveyor belts. The labels can be positioned in a range of positions on the items or containers. In most cases, the label positioning is synchronized with the conveyor speed and direction. This enables correct positioning of the label and makes it easy to collect the finished products.
Label applicators, also known as label dispensers, apply pre-printed labels with a pressure-sensitive adhesive to products and containers while they’re being transported. They’re available in a wide variety of models and can be configured to accommodate many different types of items or containers. These machines are often maintained by workers on the plant floor. They can apply a variety of different types of labels, including shipping addresses and product information.
Some labeling machines can also print on a wide variety of materials, including clear or white paper and film. They can also dispense labels in a number of formats, from circular to rectangular or square. Some can even dispense RFID labels, which provide additional security and tracking capabilities. For efficiency, these machines also come with a rejection unit that automatically sidelines any labels with errors. This allows the machine to run continuously without stopping for any manual intervention.
Tamping
Tamper-evident labeling machines dispense pressure-sensitive labels on cartons, containers, trays and boxes to protect the packaging from counterfeiting and manipulation. The labels can also carry the production information, batch number and expiry date. This type of labeling machine is ideal for pharmaceutical syrup bottles, electronic accessories and micro-chips.
The tamp-blow label applicator uses a tamp pad that holds the label while it’s blown down. As the product moves down the conveyor, a sensor triggers the label to extend. Then, the label is tamped onto the container. If the tamp is too soft, the Labeling Machine label can become loose or fall off. On the other hand, if the tamp is too hard, it can cause the label to stick unevenly to the product.
A rotary tamp is an alternative to the air-blow label applicator. It can rotate the label before it’s blown down, which helps ensure that the label is in the correct position for your container. This can save time and money because the tamp doesn’t have to move as much to align the label with your container.
Tamp-blow label application is a good choice for fast-moving products, since it doesn’t need to synchronize the printing and application of labels with the conveyor system. However, it requires a tamp pad that is calibrated to match the product’s surface and label adhesive. It’s also important to use a labeling machine manufacturer compressed air source that is free of contaminants like water or dirt, as these can damage the tamp pad.
Conveyor
When it comes to industrial labeling machines, the conveyor system is vital. This component ensures that all parts of the machine are coordinated and perform their tasks at the appropriate time. The conveyor system also helps the machine maintain speed as it goes through its labels. This is especially important in high-speed production.
Labeling machines are commonly found on assembly lines for different products. This type of machinery uses pressure-sensitive labels to label unstable items in an assembly line. It also has a roller spacing design that makes it easy to label containers of varying shapes and sizes. It can be used to label partially or fully unstable products, making it one of the most popular choices for a wide range of business applications.
The conveyor system on a labeling machine is connected to the motor and other components to power it up and facilitate its continuous motion. The conveyor is usually made of metal plates that can be adjusted to fit the container size and shape. This allows the machine to accommodate various product sizes and shapes without compromising the accuracy of its print and application process.
The conveyor also includes a sensor to detect fallen bottles or products. Once the product reaches the conveyor, it is gapped and the label is attached to it. After that, the machine will continue its labeling process. It also has a control panel that monitors real-time production, intervention, and safety aspects.
Detection
A labeling machine must be able to accurately apply labels on bottles of different shapes and sizes. To do this, it must have sensors that help coordinate the movements of various parts of the machine. These sensors are also key to ensuring that the machine is working correctly.
The most important function of a sensor on a Labeling Machine is to detect the gap between the label and the container. To do this, it uses a light source and an optical detector. There are several different types of light and optical sensors available, but they all have their strengths and weaknesses. To make the right choice, it is important to understand how each technology works and its advantages and disadvantages.
Capacitive sensors use a light to detect the gap, and they can be sensitive to metallic ink or artwork. The metals in these materials look very thick to the sensor, and they can cause it to trigger multiple times as the label passes through the gap. A skilled operator can usually adjust a capacitive sensor to work with solid metal labels, but it is not always possible.
Optical fork sensors are a type of thru-beam sensor that has the sender and receiver built into a single device. They are often used for gap detection, but they can also be used for detecting small parts and positioning robot arms. They are based on optical principles and are very versatile, but they require careful adjustment to detect all label materials.
