  • Publication number: 20230406032
    Abstract: An envelope processing apparatus includes a flap opener, a first envelope detector, a second envelope detector, and circuitry. The flap opener opens a flap of an envelope during conveyance of the envelope in an envelope conveyance passage in which the envelope is conveyed to an enclosing position. The first envelope detector detects the envelope at a position upstream from the flap opener in a conveyance direction of the envelope. The second envelope detector detects the envelope at a position downstream from the flap opener in the conveyance direction. The circuitry causes the flap opener to execute an opening operation of the flap of the envelope conveyed to the enclosing position and causes the flap opener to execute the opening operation of the flap again when an opening-and-closing state of the flap determined based on detection results of the envelope by the first and second envelope detectors is abnormal.

  • Publication number: 20230399192
    Abstract: An enclosing device to insert an enclosure into an envelope conveyed to an enclosing position includes an envelope conveyor and an enclosing unit. The envelope conveyor conveys the envelope to the enclosing position. The enclosing unit opens a frontage of the envelope such that the enclosure is inserted into the envelope that has reached the enclosing position and includes an opening amount adjuster to adjust an opening amount of the frontage when the enclosure is inserted into the envelope. The opening amount adjuster adjusts the opening amount, depending on a flap length and a body length. The flap length is a length of a flap of the envelope in a conveyance direction in which the envelope is conveyed to the enclosing position. The body length is a length of a body of the envelope in the conveyance direction.

  • Publication number: 20230331029
    Abstract: An envelope processing apparatus that inserts an enclosure into an envelope includes an envelope conveyor, a flap opener, an enclosure pusher, and circuitry. The envelope conveyor extends in a vertical direction and conveys the envelope to an enclosing position via an envelope conveyance passage as a passage in which the envelope is conveyed. The flap opener opens a flap of the envelope. The enclosure pusher pushes the enclosure toward an opening of a body of the envelope conveyed to the enclosing position with the flap open. The circuitry changes a pushing amount of the enclosure into the envelope and adjusts the pushing amount based on the opening of the body of the envelope within a specified range from an inside to an outside of the body of the envelope.

  • Publication number: 20230258281
    Abstract: A valve V1 capable of detecting an operation abnormality has a magnet M1 that is attached in the vicinity of a pressing adapter 52 of a stem 53 that slides according to an opening/closing operation of the valve V1, and a magnetic sensor M2 that is attached to a surface acing the stem 53, inside the pressing adapter 52 that presses a peripheral edge of a diaphragm 51, and detects a change in a distance between the magnet M1 and the magnetic sensor M2. Further, an abnormality determination mechanism compares the change in the distance between the magnet M1 and the magnetic sensor M2 at the time of abnormality diagnosis detected by the magnetic sensor M2 and a previously measured change in the distance between the magnet M and the magnetic sensor M2 at the time of normality, and determines whether or not there is an abnormality.

  • Publication number: 20220379653
    Abstract: An enclosing-sealing apparatus includes a flap opener that opens a flap of an envelope while the envelope is conveyed to an enclosing position. A first envelope detector is disposed upstream from the flap opener in an envelope conveyance direction and detects both ends of the envelope in the envelope conveyance direction. A second envelope detector is disposed downstream from the flap opener in the envelope conveyance direction and detects both ends of the envelope in the envelope conveyance direction in an open state in which the flap opens. A controller determines the open state of the flap based on a first detection result sent from the first envelope detector and a second detection result sent from the second envelope detector. The controller performs troubleshooting for enclosing the enclosure into the envelope if the controller determines that the open state of the flap is faulty.
