Abstract: In the present invention, constructed is a highly reliable system that does not allow unforeseen conditions to occur in the remote diagnosis of a clamp device. All combinations of status of a state detection switch mounted on a clamp device are anticipated in advance by a recursive method, and the states are defined with no omissions. A control unit 9 includes: a main body memory 9c that stores the ON/OFF state of a state switch together with the status of an injection molding machine main body, the clamp status and time information; and a main body communication unit 9d which is capable of short-range wireless communication. A message diagnosing a failure is stored in a smartphone 12 for all combinations of the ON/OFF state of the state detection switch for each of the following cases: whether in mold replacement mode or not; and whether a clamp device is in a clamped state or an unclamped state, or in a state other than the forgoing. The history of the ON/OFF state of the state detection switch with respect to the status of the main body and the clamp status is read from the main body memory 9c by wireless communication, and a corresponding message is displayed.

Abstract: An ascent-detecting air supply port (33), a descent-detecting air supply port (43), and an air discharge port (44) are provided to a housing (2). The ascent-detecting air supply port (33) is communicatively connected to an air outlet (38) by an ascent-detecting air passage (39). The descent-detecting air supply port (43) is communicatively connected to the air discharge port (44) by a descent-detecting air passage (45). The descent-detecting air passage (45) is closed by a valve mechanism (49) including: a valve surface (50) provided on a piston portion (15); and a valve seat (51) provided on an inner surface of the housing (2), when an advance piston (14) is retracted to a lowered position.

Abstract: An element changer includes a plurality of operation pin members (4) inserted in a housing (3). Each of the operation pin members (4) has a wedge surface (12c). When the operation pin members (4) are pushed into the housing (3), each wedge surface (12c) is disengaged from an engaging portion (10a) provided at a leading end portion of a tubular wall portion (10) of a tool plate (2) or of a connection plate (1). This allows a tool (5) functioning as a second element to be detached from a robot arm (8) functioning as a first element.

Abstract: A support rod (3) is inserted in a housing (1) so as to be movable in an up-down direction. An actuation chamber (21) is provided in a lower end portion of the housing (1). An output member (24) is moved upward by pressurized oil supplied to the actuation chamber (21). In the actuation chamber (21), to which pressurized oil is supplied, a release spring (33) is attached between a leading end wall (31) of the actuation chamber (21) and a flange portion (25a) provided to a base end portion of the output member (24). The release spring (33) biases the output member (24) downward.

Abstract: An output member (7) is inserted in a housing (5) so as to be movable in a left-right direction. A lock chamber (20) is provided to the right of the output member (7), as a first actuation chamber. Compressed air is supplied to and discharged from the lock chamber (20) through a first supply and discharge passage (24) provided in the housing (5). A first holding valve (30) provided to an intermediate portion of the first supply and discharge passage (24) is configured to close and open the first supply and discharge passage (24).

Abstract: An advancing-retracting member (3) which is tubular is hermetically inserted into a housing (1) so as to be movable in an vertical direction. An advancing-retracting mechanism (13) is provided to the housing (1) so as to move the advancing-retracting member (3) in the vertical direction. A support cylinder (17) is provided in a manner so as to protrude upward from the advancing-retracting member (3) and be insertable into a hole (21) formed in a workpiece (20). A pressing surface (4) formed in a top end portion of the advancing-retracting member (3) is able to push the workpiece (20) up. In a case where the advancing-retracting mechanism (13) moves the advancing-retracting member (3) upward, the advancing-retracting member (3) causes the support cylinder (17) to be inserted into the hole (21) of the workpiece (20) from below, and the advancing-retracting member (3) presses against the workpiece (20) via the pressing surface (4) so as to move the workpiece (20) upward.

Abstract: A piston (4) is inserted in a housing (1) so that the piston (4) is vertically movable. A housing hole (5) is vertically provided in the piston (4), and an output rod (6) is inserted in the housing hole (5) so that the output rod (6) is vertically movable. A converting mechanism (22) converts vertical movement of the piston (4) into rotary movement of the output rod (6). A guide groove (28) is provided in a circumferential direction on an inner circumferential wall of the housing hole (5), and a stopping part (29) is provided at an end part, in the circumferential direction, of the guide groove (28). An engaging member (31) which is provided on an outer circumferential wall of the output rod (6) is caused to face the stopping part (29) of the guide groove (28) at a given distance in the circumferential direction from the stopping part (29) so that the engaging member (31) can be in contact with the stopping part (29).
