same plant, only more reliable
The pallet conveyor system connects the approx. 100 meter long section between goods receipt, picking area and high-bay warehouse. In detail, the
System consisting of two central transverse transfer cars, 21 roller conveyors, five lift tables, 23 chain conveyors, one vertical conveyor, one longitudinal transfer car, one turntable, one scale, and two contour controls. The steel structure, which serves as the basic framework of the plant, was of good quality and should therefore be retained; the company was also satisfied with the basic performance.
Modernization was therefore the means of choice for SMS Siemag. TELOGS had to overcome two hurdles in the process: incomplete technical documentation for the plant and handling during ongoing 2-shift operation.
the implementation At the beginning of the project, it turned out that all moving parts, drives and sensors had to be replaced – this affected about 75 percent of the plant. This recording was followed by a construction phase. “Many parts that were required for the modernization were no longer available and therefore had to be newly developed. In the mechanical area, this concerns around 70 percent of the components,” explains Marc Punzert, project manager at TELOGS GmbH. Before the newly designed prototypes were mass-produced and installed, TELOGS tested them on a pilot conveyor. Another project challenge only became apparent during the implementation phase: universal assemblies based on standard parts were developed and manufactured for the conveyors. However, the conveyors had a large tolerance, so the majority of the components had to be customized. In addition, TELOGS integrated a 73-meter conductor rail on the longitudinal transfer car.
TELOGS supplied a total of 130 sensor elements and 43 drives, all of which differed in design from the previous drives, so that the conveyors and the adaptation had to be adapted in detail here. The realization phase lasted a total of eight weeks. The implementation of the work was carried out exclusively during the night and on weekends. The retrofit expert organized his assignments in such a way that the customer found a functioning system again the next morning or at the beginning of the new week.
- Modernization during ongoing 2-shift operation and full capacity utilization of the warehouse
- Within eight weeks, the entire mechanics, drive technology and sensor technology were replaced
- Technical documentation of the plant was no longer complete
- 70 percent of the spare parts were newly designed
