Pillow packaging machine system solution

High speed smooth operation, simple operation, flexible and efficient

The traditional pillow packaging machine's horizontal sealing knife motion curve is achieved by a mechanical cam, which is complex to install, has high operating noise, is difficult to adjust, and has low efficiency. The Xinje pillow packaging machine system covers high-speed, stable and smooth operation of the belt and ruler tailstock, with fixed length, fixed mark and non fixed length packaging, including functions such as anti-empty bag, torque anti-cutting material, photoelectric anti-cutting material, etc.

Industry background

Pillow packaging machine is a horizontal three sided sealing equipment that can complete processes such as bag making, filling, sealing, cutting, and finished products. It is widely used in automated production lines for food, hardware, daily chemical, pharmaceutical and other industries for flow packaging. Suitable packaging materials are generally block shaped or cylindrical regular items, such as cookies, cakes, noodles, cosmetics, tissues, etc. The packaging machine for the belt tail frame can package products of varying lengths, such as bread, electrical conduits, and other products.

System principle

The film and material feeding of the pillow packaging machine are synchronized, and the position of the feeding is detected by color code detection and proximity switch respectively. The film is formed into a cylindrical film by the forming machine and undergoes longitudinal heat sealing. At the same time, the material is fed into the cylindrical film and passes forward through the transverse sealing cross section. The cylindrical film is horizontally sealed and cut by a rotary or reciprocating transverse sealing cross cutting knife, and the packaged product is output.

The film feeding axis needs to pass through a bag length for each rotation of the horizontal sealing knife axis, and the feeding film axis needs to deliver one piece of material. This process requires the three axes to remain synchronized at all times. The most important thing is that the speed of the horizontal sealing blade axis at the moment of sealing must be consistent with the speed of the plastic film, otherwise it may cause the plastic film to break or pile up during horizontal sealing.

System function

Stronger system stability and anti-interference ability

The electronic cam and high-speed computing function of the Xinje PACK-30 motion controller play a crucial role in ensuring the machine operates at high speed and stability while maintaining precise cutter position.

Anti-empty bag function

This is a unique feature of the new three-servo automatic packaging machine, which can achieve no empty packaging of finished products.

Optoelectronic anti-cutting function

The photoelectric anti-cutting function is achieved through three-axis independent control of motion, which improves packaging efficiency and protects the transverse sealing knife from mechanical damage.

Electronic cam function

In transmission and control systems, electronic camshafts are used instead of traditional mechanical camshafts to achieve various complex reciprocating motions, and the function of analog camshafts is achieved through digital systems.

Electronic cam features

There are no mechanical contact failures such as inertial stress, elastic deformation, and rigid impact force in mechanical cam systems, making them more suitable for high-speed motion transmission scenarios.

There is no wear and tear, and the shape of the cam transmission curve will not change as long as the design is completed. Therefore, the accuracy and stability of the expected motion of the driven component are higher and better when repeated.

It is convenient to change the motion transmission curve, and different motion transmission curves can be achieved by changing the corresponding motion parameters, greatly reducing production, installation, and replacement costs.

Solution advantages

Automatic Level Calculation

Automatically calculate the material position, realize one key startup after system initialization, minimize waste, and support the adjustment of bag length, tangent point and feeding position during operation.

No Mechanical Adjustment Needed

The bag length can be set arbitrarily, ranging from tens of centimeters to several meters, and is automatically generated by the cam function in the PLC without any mechanical adjustment.

Electronic Cam with High Flexibility

The internal use of electronic cam has high flexibility, so the specific speed of the equipment is determined by the number of cutting blades, blade roller diameter, packaging bag length, servo rated speed, and mechanical reduction ratio. For the appropriate bag length and transmission ratio, the fastest single blade can reach 200ppm.

Pulse + EtherCAT Bus Dual Solution

The dual scheme of Xinje Pulse + EtherCAT bus is more suitable for applications of high and low-end models. The EtherCAT bus scheme controlled by XDH series PLC has simple wiring, strong anti-interference, high accuracy, and strong universality, making it easy to expand and maintain in the later stage.

High Precision

Using servo probe function, the accuracy can reach up to 0.5mm.
