Patent ID: 7891223

Claim:
A transfer press machine including a press machine which can press a material by using a press operation of a slide and a material transfer device which can transfer a material to the press machine by using a transfer operation of a finger, the press machine and the material transfer device being disposed in real space to have a specific relative positional relationship with each other, the transfer press machine operable to press a material transferred during a transfer press cycle in which the press operation and the transfer operation are synchronized, and the transfer press machine comprising an interference check device, the interference check device including: a data-conversion constituent element storage section which stores a press-side data-conversion constituent element, which is a constituent element of the press machine and is converted into three-dimensional shape data, and a transfer-side data-conversion constituent element, which is a constituent element of the material transfer machine and is converted into three-dimensional shape data, in a state of being placed in virtual space to have the same relative positional relationship as in the real space; a virtual press operation control section which causes the press-side data-conversion constituent element placed in the data-conversion constituent element storage section to perform a virtual press operation in the virtual space according to a press motion; a virtual transfer operation control section which causes the transfer-side data-conversion constituent element placed in the data-conversion constituent element storage section to perform a virtual transfer operation in the virtual space according to a transfer motion; a virtual synchronization timing information generation-output section which generates and outputs virtual synchronization timing information for causing the virtual press operation control section and the virtual transfer operation control section to execute a virtual transfer press cycle in which the virtual press operation and the virtual transfer operation are synchronized; and a virtual interference determination section which determines whether or not interference occurs between the press-side data-conversion constituent element and the transfer-side data-conversion constituent element during the virtual transfer press cycle, whereby interference in the virtual space is checked without executing the transfer press cycle in the real space.
