In food packaging production lines, material handling and transportation is an important link. Servo manipulators can replace manual labor to complete the handling of food raw materials, semi-finished products and finished products. Compared with traditional manual handling, servo manipulators have the following advantages:
Fast speed: The servo motor can start and stop quickly, and the manipulator can complete a large number of material handling tasks in a short time, greatly improving production efficiency. For example, on a bread production line, a servo manipulator can quickly take bread out of the oven and place it on a cooling rack, and then move the cooled bread to the packaging machine. The whole process is coherent and efficient, saving a lot of time.
Higher precision: The servo system can accurately control the position and speed of the manipulator to ensure the accuracy and stability of the material during the handling process. For some fragile, deformable or irregularly shaped foods, such as eggs, biscuits, etc., the servo manipulator can adjust the gripping force and movement trajectory according to its characteristics to avoid damage to the food and ensure the integrity and quality of the product.
Stronger stability: The servo manipulator is not affected by factors such as fatigue and emotions, and can operate stably for a long time, reducing packaging delays or defective products caused by unstable or mistakes in manual handling. At the same time, the vibration and noise generated during its operation are small, which is conducive to improving the working environment and the service life of the equipment.
(II) Packaging Forming and Sealing
Servo manipulators also play an important role in the forming and sealing of food packaging. For example, in liquid food packaging, such as milk and juice, servo manipulators can accurately control the opening and closing of packaging bags and the sealing force to ensure the sealing and appearance neatness of the packaging.
Accurate packaging forming: Through programming control, the servo manipulator can fold and shape the packaging materials according to the preset shape and size, so that the packaging bag fits the shape of the food tightly, reducing the waste of packaging materials, and improving the beauty and consistency of the packaging. For example, in candy packaging, the manipulator can accurately fold the wrapping paper into a specific shape, wrap the candy tightly, and form a beautiful packaging appearance.
Reliable sealing effect: During the sealing process, the servo manipulator can accurately adjust the sealing temperature, pressure, time and other parameters according to the characteristics and packaging requirements of different foods to ensure that the mouth seal is firm and reliable, prevent the influence of external factors such as air and moisture on the quality of food, and extend the shelf life of food. For example, in the vacuum packaging of meat products, the servo manipulator can accurately control the sealing device to ensure that the vacuum degree in the packaging bag meets the standard, the sealing is tight and leak-free, effectively inhibiting the growth of bacteria, and ensuring the freshness and safety of meat products.
