Abstract [en]

Forestry and processing of timber have a long tradition in Sweden and the Swedish forest industry plays a significant role in the country's economy and exports. Wooden apartment buildings are on the rise in Sweden, and the technology and production methods for the construction of multi-storey apartments are in place. Cross-laminated timber (CLT), a wood product made of glued cross-laid boards of sawn timber, is a construction material proven to be effective for the construction of wooden multi-storey buildings. Swedish wood products industries need to transit from manual labour to automated production lines to remain competitive in the global market. Södra, an association of forest owners is a manufacturer of CLT panels and sees the need of implementing a new automated process for pre-drilling of CLT panels. A concept for a robotic pre-drilling application is developed through a general process of product development. A robotic application consisting of a stationary robot with dynamic material placement is selected as the best concept for the robotic pre-drilling application. The CLT panel is repositioned by a conveyor so that the robot can reach the drilling positions. For the concept to be effective, it is necessary to synchronize both the conveyor and the robot to coordinate and work together. The robotic pre-drilling application is modelled, programmed, and simulated in RobotStudio. In the simulation, an IRB 7800 robot is used, and 24 holes in angles of 30° - 90° relative to the surface normal are drilled in the CLT panel. The cycle time of the operation is three minutes.
