Embodiment Construction

[0035] Hereinafter, an example in which the present invention is applied to a signal processing device of an injection molding machine will be described as an embodiment of the present invention.

[0036] FIG. 1 is a block diagram showing an essential part of an embodiment of a machine signal processing device according to the present invention. A logical operation execution unit is provided in a control device for controlling a machine (injection molding machine), and the control device and the machine (injection molding machine) are used ) has a display device and an input device, constituting a signal processing device.

[0037] In FIG. 1, reference numeral 1 is a control device for controlling a machine (injection molding machine) 2, and the control device 1 has a CPU and a logical operation execution unit 1a for performing logical operations according to a sequence program described later. This control device 1 is connected to a nonvolatile RAM 4 and a RAM 5 storing a seq...

Abstract

First and second OR operation fields for setting signals that represent the states of the machine are provided on a setting screen. Carrying out OR operation on signals set in the first OR operation fields and carrying out OR operation on signals set in the second OR operation fields, AND operation is carried out on the results of those OR operations to provide an output signal.

Description

technical field [0001] The present invention relates to various mechanical signal processing devices. Background technique [0002] Conventionally, in various machines, a signal of a predetermined logical operation result is output at a predetermined timing in order to operate peripheral devices and the like arranged with respect to the machine in accordance with the operating state of the machine. For example, in an injection molding machine, it has been conventional to output a signal in a metering process during fully automatic operation or semiautomatic operation of the injection molding machine as a signal for operating a quantitative supply device for supplying resin to the injection molding machine. . At this time, a signal such as [(in fully automatic operation) OR (in semi-automatic operation)] AND (in measurement) can be output. [0003] As the signal for the quantitative supply device mentioned in this example, since the timing or logical operation is simple, it...
