GEFRAN SOLUTIONS FOR PACKAGING

Gefran offers a complete range of solutions for packing and packaging machines: from acquisition of physical machine variables to closure of the control loop with actuators such as solid state relays and power solid state relays with heatsink and the range of Gefran-Siei drives.

Four channels of Temperature Control

SEALING
Exclusive "All in one" solution

COMPACTNESS GFX4 represents an innovative and exclusive solution for temperature control of the sealing bars used extensively on packaging machines for package sealing. A single compact device, arranged for DIN rail mounting, includes fast and precise temperature control functions, as well as solid state relay and heatsink, integrated current transformer for load control, extrafast fuse and fuseholder, all multipled by four independent and programmable channels. Savings in terms of space and wiring are absolutely guaranteed. Connectivity of the GFX4 with the machine controller or directly with the operator panel is made easier by the available of Modbus RTU, CANopen, Profibus DP, DeviceNet, Modbus TCP.

Dosage/weighing control

SPEED The new "2400" fast indicator/interceptor, (sampling time just 2 msec) can manage independent multiple weighing processes. The two high resolution (100,000 points) universal inputs directly accept connection with load cells (typically, Gefran OD models). The four available outputs can be freely set to reference channel 1 or channel 2. A Modbus RTU communication line with baudrate programmable up to 115200 bps conveys weighing information directly to the control system, where it is possible to introduce the individual weighing setpoints and other operational parameters

Positioning control

PRECISION AND STURDINESS In vertical packaging machines, as in horizontal wrapping machines, position transducers are often used to appropriately position the sealing bar, or to measure the dimensions of the different objects to be packaged. For these applications, the model PZ potentiometric displacement transducers, with double self-aligning joints at each end, are perfect. Or you may choose the model PC for applications requiring greater sturdiness and IP protection (up to IP67).

GEFRAN offers a wide range of components for automating primary processes in the wood industry, as well as complete solutions, from sensor to actuator, for work processes and coupling of materials, surface finishing, painting, and storage:
- displacement, force, pressure transducers for precise positioning of mechanisms (size settings, cutting, etc.) and machine parameter control systems.
- sensors, controllers, programmers and actuators for all processes with heating phases (spreading, gluing, drying, bending, edging, etc.), and for programmed control of ambient parameters (humidity and temperature) in seasoning systems.
- positioners and level indicators for sanders.
- configurable indicators to display (on the machine or control panel) other parameters such as input/rpm’s, pieces produced, etc.
Choosing GEFRAN means giving added value to your system in terms of production flexibility, precision and repeatability, guaranteed by components that can sustain a high number of cycles under harsh conditions.

GEFRAN SOLUTIONS FOR METALWORKING

GEFRAN offers a wide range of automation components for metalwork plants and machines, from melting to heat treatments, from deformation to surface finishing to cutting systems: - displacement, force, pressure transducers for precise positioning of mechanisms (for example, press rollers, tools) and machine parameter control systems - sensors, controllers, programmers and solid-state actuators for heat control and the running of temperature profiles (for example, in electric or gas furnaces for heat treatment of metals, washing and drying systems) - level indicators and positioners (for rollers, benders, sanders, etc.) - maximum/minimum alarm units for safety devices - configurable indicators to display (on the machine or control panel) other parameters such as input/rpm’s, pieces produced, etc. - phase angle power solid-state relays to control voltage on transformer primaries (for example, in the furnace industry, welding, etc.). - Gefran-Siei Servo drives for metal sheet cutting lines, including special software application for transversal cutting systems equipped with Feeder or Flying Shear.
