Abstract: The method comprises a measuring step and a separate aligning step. The alignment of guide rails supported with adjustable fastening means in the shaft is measured in several measurement points along the height of the guide rail line based on at least one reference line provided in the vicinity of the guide rails. The measurement results are stored into a memory. The guide rails are aligned based on the measurement results stored in the memory. The aligning step is carried out after the measurement results of all measurement points have been stored in the memory.

Abstract: The method comprises measuring the position of two opposite guide rails in respect of the DGB direction and the BTF direction with a plumb line and a measurement device arranged at each guide rail. Each measurement device comprises a guide shoe being supported on at least two guide surfaces of the guide rail, a measurement frame connected to the guide shoe, and sensor means for sensing the position of the plumb line in respect of the measurement frame. The twist of the guide rails is measured with a wire extending between the two measurement devices and an edge sensor arranged in connection with at least one of the two measurement devices.

Abstract: An assembly line comprising a number of pallets (1) carrying electronic components for assembly, provided with individual RF-tags (2) containing stored product information, a main conveyor (3) in the shape of an endless loop, conveying pallets (1); assembly stations (4) spaced along the main conveyor. Each station is equipped with a reading device (6) for reading the RF-tags and a data processing apparatus controlling the work station operations, depending on the data read off the RF-tag; an automatic storage system (7) placed in the vicinity of workstations (4) comprising a number of storage devices (8), as well as transfer means (9) feeding pre-selected components from a pre-selected storage device to the assembly stations.

Abstract: Apparatus for automatic execution of operations in the fabrication of circuit boards or similar boards. The apparatus comprises a conveyor (4) consisting of two parallel conveyor halves (5, 6) provided with a traction element (7) to convey the circuit board. The conveyor halves, guided by a first set of guide bars (8, 9), can be moved in a direction transverse to the conveying direction while remaining parallel to each other, to permit adjustment of the width of the conveyor; a 3-D transfer gear (10) disposed above the conveyor (4) and provided with a gripper (11). The apparatus is provided with tools (12) which can be manipulated by the gripper (11) of the transfer gear, and a control unit (13).
