Abstract: An apparatus for detecting a pallet full load state determines a pallet full load state while switching the upper limit value of the mounting height of workpieces according to workpiece size. The controller of an apparatus for controlling a sheet metal machining line estimates an occurrence or non-occurance of a pallet full load state. A pallet full load state is defined as a function of the overall height or the total weight of the workpieces loaded on the carrier pallet. The controller estimates an occurance or non-occurance of a pallet full load state by analyzing the machining schedule when a machined workpiece is loaded on the carrier pallet has a replacing carrier pallet suitable for the next workpiece to be loaded standby whenever appropriate.

Abstract: A cell controller is provided that analyzes each unit machining schedule, which is referred to for manufacturing products, prior to the start of the assigned unit machining schedule. The data items in the schedule are analyzed include identification numbers of machining programs, the use or non-use of such identification numbers, the number of workpieces to be machined, and a presence or absence of predetermined procedures (e.g., for exchanging metal molds, etc.) that are referred to for manufacturing the products. An operator is notified of any foreseeable schedule alarm condition, that will force the operation of the line of manufacturing products of a specific item to be suspended, so that the operator may be informed of the situation in advance. The foreseeable schedule alarm condition may arise for reasons such as an insufficient number of available workpieces and/or preparatory work to be done (e.g., an exchange of metal molds, etc.).

Abstract: A machine tool control system is provided that is capable of detecting a one-sheet takeout failure. The system includes a workpiece takeout schedule which indicates the plate thickness and number of sheets to be taken out from a stack of workpieces for each product.

Abstract: A master cylinder includes a second piston that is provided with a hollow portion. The hollow portion includes a yoke portion for receiving an end of the second return spring, a cylindrical portion having a diameter that is larger than the diameter of the second return spring, and a tapered portion located at the open end of the hollow portion. The second return spring is disposed within the yoke portion so that the second return spring is coaxially arranged with respect to the second piston. Thus, although the second return spring is capable of moving rapidly to and fro within the hollow portion, the construction of the second piston and the arrangement of the second return spring within the hollow portion of the second piston helps avoid interference between the second piston and the second return spring. Thus, unpleasant noise can be reduced or eliminated. Moreover, small particles that would normally result when the second return spring scratches the second piston are not as likely to arise.
