Advantages
Feeder acceleration.
In most applications, belt travel time depends more on feeder acceleration than on its maximum speed. Thanks to optimized kinematics, Coiltech feeders can achieve an acceleration of 25 m / s2 and a maximum speed of 200 m / min.
The roll release is operated by a solenoid valve and special pneumatic cylinders or 2 cylinder-controlled hydraulic cylinders, which provide a rotation speed of up to 300 rpm. Up to 1000 copies per minute can be achieved with mechanical release control. All Coiltech controllers have a special maintenance screen showing real-time input/output status.
Mobile unit design.
Such levels of performance can only be achieved through extremely careful design of all feeder components. The rudder body – the moving part of the feeder, consists of a cast-iron structure made with great precision. It is precisely guided by needle bearings and thrust ball bearings mounted on 2 pivots. The release stroke is limited by a mechanical stop, adjustable according to the thickness of the belt.
Motion is transmitted to the upper roller by the original 4-tooth kinematic chain. Bounce in the gear is very low, regardless of metal thickness.
HI-Q rollers.
For the best grip and long life, all rollers on Coiltech feeders are hardened, ground in micrometers, then hardened and chrome plated at 70 HRC. On the largest movements for better dynamics, the rollers are tubular and supported by support rollers.
Precision.
All Coiltech feeders are equipped with low-inertia brushless motors and reduced-backlash gears. Feed accuracy will therefore be determined mainly by the quality of the signal measurement and processing sequence. The use of a complete electronic package (sensors, motors, PLCs) from the same component manufacturer among the world leaders, ensures exceptional reliability and positioning accuracy (± 0.05 mm)
Coiltech feeders can be equipped with OMD option suitable for developing delicate materials (pre-painted, galvanized, copper, mirror, aluminum…).
Protection.
An additional feed measurement device can be installed on the belt, either below the CRM / B or above the CRM / T. This sensor makes it possible to monitor the slip between the feed motor encoder measurement and the actual passage of the belt in real time.
In this way, any malfunction of the tool or press can be detected, cause an immediate stop or prevent damage to the installation.
Mounting to the press.
The feeder can be mounted to the press in two ways. The first is by means of a fixed mounting bracket which is manually adjustable in RCH height and actuated by the RMH-C motor. The second way is an independent frame, activated by the RMH-S motor for the largest equipment. The brain of the feeding line is thus digital control. It optimizes the operation of the various machines and communicates with the other parts of the feeding line. So we see that the terminal is the main component of the man-machine interface.
The choice of control will be made according to the size, number and complexity of the various components of the cutting line (decoiler, straightener and other peripherals). The required degree of automation and communication and the customer’s available budget will also be taken into account. He will be able to find a system that fits his application among the four controllers.
Our development department works every day to ensure that our solutions are innovative and the best available on the market. Expanding on its expertise, Coiltech will provide your company with: a coil sheet uncoiler, a sheet straightener and a press feeder.
Digital control – the brain of the feeding line.
It optimizes the operation of the various machines in it and communicates with other parts of the cutting line. The terminal is the main element of the man-machine interface. The choice of control will be made depending on the size, number and complexity of the various parts of the cutting line (unwinder, press tool and other peripherals). The required degree of automation and communication and the available budget will also be taken into account. From among our 4 controls, you will be able to find the system that fits the appropriate application.
