Using the MZ2Q cylinder sensor, both end positions on short-stroke cylinders are detected in forming machines for confectionery.
A business that, among other items, manufactures forming machines for solid and filled chocolate products, as well as sweet casting machines, was looking for a compact sensor with two adjustable switching points in one housing for the numerous short-stroke cylinders installed in the machines. By detecting the start and end of the stroke movements on the pneumatic cylinders, it is intended to achieve improved process reliability and availability.
This task was realized using the MZ2Q magnetic cylinder sensor from SICK. The device has two adjustable switching points and, at the same time, is so compact that it can be fitted and fastened in all common T and C housing grooves with drop-in mounting. The miniature design was made possible by the separation of the sensor element and electronics. The evaluation electronics for the MZ2Q as well as the teach element for teaching in the switching points are integrated into a remote control unit in the connection cable, separate from the sensor element. As a result it is also easy to adjust and fine-tune the switching points even when installed.
In terms of the design, the application and economic aspects, the MZ2Q is the optimal solution for the detection of two switching points. Recent example calculations in which the MZ2Q is used as an alternative to two separate magnetic proximity sensors, each with only one switching point, produced cost savings of up to 30 %. The key issue here is the reduction by more than half in time required for the mounting and adjustment of the MZ2Q. Qualitative aspects also have an impact, e.g. usage of only one groove, less cabling on the cylinder and in the machine, and improved access to the sensor when the cylinder is already installed.
This is an application from SICK.
