Interlink system for high process reliability

0

mk Profile Systems explains how its conveying solutions have provided an interlink system and stacking magazine for a manufacturer of office supplies.

The office supplies manufacturer bought a new cutting machine for the production of files. The machine needed to be integrated into the production hall and linked to the existing conveyor system. It was essential that the cut blanks be stacked on the interlink system before being transported further. There was also a requirement to process different formats, from 616 x 318mm to 675 x 350mm in size. The cutting machine needed to run continuously and be capable of processing up to 100 blanks per minute.

mk supplied the interlink system solution, which consisted of a stacking magazine, conveyor section and transfer so that it could connect to the existing conveyor system. The blanks fall continuously from the cutting machine into the stacking magazine. The magazine can be adapted to different formats using clamping levers. Once enough blanks are stacked, the first stack is transported onward. Meanwhile, the second stack begins to accumulate. The pawl for collecting the second stack must be extended within 0.6 seconds in order to correspond to the cycle time of the cutting machine. At the end of the line, the stacks are conveyed by means of a roller conveyor and a timing belt conveyor aligned transversely to the transfer onto the existing conveyor system. The transfer was provided with a cover that complies with accident prevention regulations. mk programmed the entire controller for the interlink system, including interfaces for the material flow. This element can, therefore, be operated independently and integrated into the customer’s higher-level safety circuit.

The mk solution has provided the customer with a customised solution based on a well-engineered standard modular system. The system rewards them with high process reliability, and they have a reliable contact in mk to assist with all conveying tasks.

The ZRF-P 2010 timing belt conveyor used in this solution is ideally suited for use as a dual line system for transporting heavy workpiece carriers and products with a rigid structure. The positive connection between the drive pulley and the timing belt ensures that the two conveyor lines are synchronised, making the system ideally suited to cycling operation. Various coatings on the surface of the timing belt ensure optimal gripping of the workpiece for a specific application. Combined with the wide range of different drive options, this makes the system the perfect basis for constructing complex interlinking and automation systems.

A further feature of this conveyor system is the recirculation of the timing belt inside the profile frame. This provides a compact design and reduces the risk of accidents to a minimum.

The profile also offers system slots (10mm slot width) on three sides for connecting stands, side rails, sensors and stoppers.

This solution also made use of mk’s RBT-P 2255 tangential chain roller conveyor. This roller conveyor is used wherever long conveying paths with a motorised drive mechanism are required. The conveyor is driven by a 0.5 inch chain, which runs within an enclosed, low-wear wear strip to tangentially drive the conveyor rollers from below via a sprocket wheel. This allows users to achieve conveying paths up to 10m in length and makes the system suitable for even dirty or oily environments.

The chain tail is also equipped with idler pulleys supported by ball bearings for minimal friction losses. The tangential chain roller conveyor is available in both straight and curved configurations and can be combined with other roller conveyors (RBS and RBM). The longitudinal slots in the beam profiles can be used to attach side rails, stands, sensors and other accessories.
