Abstract
Abstract A modular machine table comprises a pair of vertical plate-like support components interconnected via horizontal transverse struts by releasable coupling devices and supporting a table plate secured by releasable coupling devices. The plate-like components are suitably of channel form and are provided with adjustable lower supports and with bores in the web for receipt of coupling means for joining adjacent tables and in the flange for mounting of a safety module or the like. The table plate is formed with bores and recesses for mounting guiding drive, coding and positioning modules and with a pattern of bores and/or slots for locating and mounting working devices. In one embodiment a table plate is provided with a turntable and two sets of guide modules intersecting at the turntable whereby a workpiece carrier may be displaced from one to another guide path. The plate-like components are arranged flush with edges of the table plates so that the plate-like components of adjacent tables may be abutted. Common parts are used for the construction of different tables in readily dissemblable manner, which are of high rigidity and which by virtue of their modular nature allow flexible arrangement of a production line.
