Abstract

A press machine includes a memory storing a plurality of function programs for changing a mode of pressing; a connection unit including a plurality of connection terminals; and a controller configured to execute at least one function program among the plurality of function programs stored in the memory, in accordance with a combination of the plurality of connection terminals of the connection unit which are each in one of a conductive state and a non-conductive state.

First claim

The invention claimed is:

1. A press machine comprising:
a memory configured to store a plurality of function programs for changing a mode of pressing;
a connection unit including a plurality of connection terminals and configured to receive a connector, wherein the connector is disconnected during operation of the press machine, wherein, when the connector is connected to the connection unit prior to operation of the press machine, a first of the plurality of function programs is stored in memory, when the connector is connected to the connection unit a state change from the first of the plurality of function programs to a second of the plurality of function programs is stored in memory, and after the connector is disconnected, the second of the plurality of function programs is stored in memory and executed during operation of the press machine; and
a controller configured to execute at least one function program among the plurality of function programs stored in the memory, in accordance with a combination of the plurality of connection terminals of the connection unit which are each in one of a conductive state and a non-conductive state.

2. The press machine according to claim 1 , further comprising a control board equipped with the connection unit.

3. The press machine according to claim 1 , further comprising the connector connectable to the connection unit, and configured to be connected to the connection unit to determine whether the plurality of connection terminals are each in the conductive state or the non-conductive state.

4. The press machine according to claim 3 , wherein
the plurality of connection terminals of the connection unit are each formed in a recess shape, and
the connector has protrusions to be fit in the plurality of connection terminals.

5. The press machine according to claim 3 , wherein
one of the plurality of connection terminals is connected to a power supply voltage, and
the connector causes short circuit between at least one of remaining connection terminals of the plurality of connection terminals and the power supply voltage.

6. A method for operating a press machine, wherein the press machine comprises a memory configured to store a plurality of function programs for changing a mode of pressing, a connection unit including a plurality of connection terminals and configured to receive a connector, and a controller configured to execute at least one function program among the plurality of function programs stored in the memory, the method comprising:
connecting the connector to the connection unit including the plurality of connection terminals of the press machine, wherein when the connector is connected to the connection unit prior to operation of the press machine, a first of the plurality of function programs is stored in the memory;
storing a second of the plurality of function programs in the memory, wherein when the connector is connected to the connection unit a state change from the first of the plurality of function programs to the second of the plurality of function programs is stored in memory;
disconnecting the connector before operation of the press machine, wherein after the connector is disconnected, the second of the plurality of function programs is executed during operation of the press machine; and
performing press working based on at least one function program among the second of the plurality of function programs in the memory, in accordance with a combination of the plurality of connection terminals which are each in one of the conductive state and the non-conductive state determined by connecting the connector to the connection unit, wherein the connector is disconnected during operation of the press machine.
