Wire- and pipe-bending machine
Tube and wire bending machines bend and cut round material. Because these machines process materials of various lengths, the area guarding at the bending head of the machines must be adaptable to different dimensions. Also important is reliable presence control
of the material – regardless of its surface characteristics.
Our easy-to-configure safety laser scanners facilitate fast configuration of different-sized protective fields for this purpose. In addition, they are very resistant to particles that may separate from the material during the machining process. Our optical sensors function largely reflection-independent and therefore reliably detect a wide range of surfaces.
Requirement:
The hazardous working range of the machine is to be guarded against entry by and the presence of persons. The contour of the monitored area is to be adapted to the contour of the machine.
Solution:
The RSL 400 safety laser scanners use configurable protective fields for area monitoring. Thanks to the 8.25 m operating range and 270° scanning range, large areas can be guarded with just one device.
Requirement:
The closed state of safety guards such as doors or flaps must be monitored. EN ISO 14119 stipulates that measures to protect against manipulation must also be provided. If this is not possible through constructive measures, the sensor must have a high level of protection against manipulation.
Solution:
Thanks to diverse installation options, the S20 / 200 safety switches can be used universally. The contactless, magnetically coded switches of the MC series are ideal for use in harsh environments. The RD 800 safety transponders with RFID coding also offer maximum protection against tampering.
Requirement:
Multiple safety sensors must be integrated into the machine or system control. Functions such as a time delay for releasing a locking device or signal connections are also to be configured.
Solution:
The basic module of the MSI 400 expandable safety control already has 24 safe inputs/outputs as well as an Ethernet interface with Industrial Ethernet protocols. The safety control can be configured quickly and efficiently using the license‑free configuration software MSI.designer.
Requirement:
The bending process should be performed with consistent accuracy for both simple as well as complex shapes. To do this, the presence control for the correct position of the pipe is to be checked to ensure that the subsequent machining process can begin reliably.
Solution:
The IS series of inductive switches offers operating ranges of up to 40 mm and a wide range of cylindrical and cubic designs. Furthermore, the models in robust full-metal construction are resistant against aggressive lubricants.
Requirement:
The bending process should be performed with consistent accuracy for both simple as well as complex shapes. To do this, the presence control for the correct position of the pipe is to be checked to ensure that the subsequent machining process can begin reliably.
Solution:
The HT 3 diffuse reflection sensors for shorter operating ranges and HT 25C for longer operating ranges ensure reliable presence control. Models with various light-spot geometries offer reliable detection of different materials. The version with IO-Link interface makes commissioning quick and easy.
