The Automated Dispensing

Among the proposed solutions, Janome robots, particularly those from the JR3000 series, stand out for their robust design and compact structure, with optimized cabling for minimal footprint. This series is particularly suited to automating complex tasks thanks to its mechanical stability and fast execution. It also features advanced connectivity, including compatibility with major industrial networks and a LAN port for remote monitoring via PC.

The JR3000 Vision version includes a complete vision system with a camera, laser sensor, and needle adjuster. These tools allow for real-time automatic adjustments, ensuring constant precision even when parts vary in shape or position. The multilingual interface, available in eleven languages, makes programming accessible to a wide range of users. Moreover, the integrated JR C-Points II software centralizes camera calibration, path and sensor management, and enables automatic corrections on the X, Y, and Z axes, as well as nozzle adjustment.

The JR3000 robots are suitable for many industrial applications such as fluid dispensing, coating, potting, greasing, and UV curing. Some models feature a dual table, reducing downtime and increasing production cycles. Their technical performance is solid, with travels ranging from 200 × 200 mm to 400 × 400 mm, maximum speed of 900 mm/s, and ±0.01 mm repeatability. Four-axis versions with 360° rotation are also available for 3D tasks.

For standard 3-axis robots, the 781 series is a standard, versatile solution for fluid dispensing. It enables accurate execution of dots, lines, circles, arcs, and fills, with various working area sizes available. Accuracy reaches 0.001 mm per axis, with a repeatability of ±0.01 mm, and it can store up to 100 programs of 4,000 points each. Control is done via a manual teaching pendant.

The 782 series builds upon this foundation by integrating a ball screw and servo motor, increasing mechanical stability and load capacity up to 12 kg on the Z axis and 15 kg on the Y axis. It also offers advanced communication interfaces, including RS232 and Ethernet. The 783 series integrates a Windows PC, making programming even more intuitive, with the ability to import DXF files to define paths, export data in CSV format, and customize functions (alerts, level sensors, etc.).

The 784 series represents the most advanced version in this range, integrating a high-resolution camera (4 MP) and laser sensor for advanced part recognition. These technologies allow automatic adjustment of the deposit to the part’s geometry and real-time needle height correction. A 19-inch LCD screen is included for easier operation monitoring.

As for 4-axis robots, the 785 series adds a rotary axis enabling deposits at any angle ideal for complex 3D applications. It includes an automatic needle calibration function and is compatible with various syringe or valve systems. The 786 series goes even further in performance by integrating ball screws and servo motors, offering reinforced stability and high precision in rotary movements, with a load capacity up to 15 kg on the Y axis and 5 kg on the Z axis.

Poly Dispensing Systems also offers a range of options and accessories to enhance its systems. The protective enclosures include a lockable case, optical barrier that instantly stops cycles in case of intrusion, and a door sensor to ensure operator safety.

Automatic recalibration systems allow precise needle alignment: optical sensors detect XY position deviations, and a Z detector adjusts the needle height after each replacement.

It is also possible to add an auxiliary rotation axis to a 3-axis robot, transforming it into a 4-axis system. This module can be mounted vertically (for multi-face dispensing on a part) or horizontally (to rotate the part itself). This is especially useful for applications on cylindrical components.
