摘要:
A method for monitoring a mounting tact of a component mounting apparatus including a component supplier for supplying a component and a component holder for holding the component from the component supplying device and mounting the component onto a circuit board. The method includes collecting and monitoring a mounting tact result value of the component mounting apparatus during a mounting operation via a communication system. The method further includes calculating a tact loss corresponding to an amount by which the mounting tact result value is greater than a standard mounting tact and monitoring the calculated tact loss.

A service receiving device is provided for in a production facility such as a component mounting apparatus. A service providing device is provided for on a manufacturer's side of the production facility. The service receiving device and service providing device are configured to communicate with each other through various communication systems including, for example, the Internet. The communication system can be operated by software to create and/or transmit service responses to problems or production matters, including productivity or quality of maintenance.
摘要:
A service receiving method for receiving a component library generated from mounted component data, including component size and mounting conditions, via a communication system that includes the Internet. The method includes the service provider receiving mounted component data having mounting conditions actually realized by a fabrication of non-defective products. The method also includes the service provider deriving a component library from a mounted component database.

A service providing method for monitoring a mounting tact of a component mounting apparatus includes collecting, from the service receiver, mounting tact information including a mounting tact result value of the component mounting apparatus from the service receiver by use of a service provider via a communication system. The method additionally includes judging whether a mounting operation of the component mounting apparatus has a tact loss corresponding to an amount by which a mounting tact is greater than a standard mounting tact as a result of analysis of the collected mounting tact information and determining and feeding back, to the service receiver via the communication system, NC data for allowing the component mounting apparatus to be operated.

A thickness detector includes a rotator having different shape marks, disposed at different positions in a rotation direction; an opposing member disposed opposite the rotator; a detector to detect and output a displacement amount of the rotator or the opposing member in a sheet thickness direction; and a controller. The controller is configured to acquire first output values for one rotation from the detector, in a state without sheet; determine, based on a value output from the detector, whether one of the plurality of marks is detected in a state with the sheet held; acquire a predetermined number of second output values after one of the marks is detected; extract, from the first output values, values corresponding to the second output values, based on the value corresponding to the detected mark; and calculate a sheet thickness based on the second output values and the extracted first output values.

A sheet thickness detector incorporated in an image forming apparatus includes a sheet conveying member to rotate and convey a sheet in a sheet conveyance direction, a driven sheet conveying member to contact the sheet conveying member and form at least one first transfer nip therebetween in a lateral direction and to displace by an amount equivalent to a thickness of the sheet passing through the first transfer nip and rotated with the sheet conveying member in the sheet conveyance direction, a displacement member to contact the sheet conveying member and form a second transfer nip smaller than the first transfer nip in the lateral direction and to displace by an amount equivalent to the thickness of the sheet passing through the second transfer nip and supported at a support member, and a displacement amount detector to detect an amount of displacement of the displacement member.
