  • Publication number: 20130095990
    Abstract: An image forming apparatus includes a recording head, a carnage, a sheet cutting device, a cutter position detecting device, and a controller. The cutting device includes a cutter and a cutter unit holding the cutter. A movement area of the carriage overlaps a movement area of the cutter unit in a thickness direction of a sheet. The detecting device detects a position of the cutter unit. The controller performs initial operation upon power on of the apparatus to move the cutter unit to a cutter home position located at one end of the movement area of the cutter unit. The cutter unit, after cutting the sheet, is movable in a width direction of the sheet with the cutter unit retracted from a sheet feed path in the thickness direction. The controller determines whether or not to perform the initial operation based on detection results of the detecting device.

  • Patent number: 5041070
    Abstract: A bag machine includes a programmed logic controller intermittently actuating a web feed draw roll motor for controlled web feed during the inoperative period of a cycled seal bar. The controller has separate inputs for the seal bar periods and a web length and establishes a control program of a preferred motion profile, with acceleration and deceleration of the fixed rolls to match the bag length to the available time using the total time available, with acceleration to a maximum and deceleration to reference, with or without a constant speed period. The bag length and time is monitored each machine cycle to calculate the next motion profile and permit changes in the bag length without machine shut-down. A programmed registered mode of control responds to a web mark spacing relative to the seal bar. In the registered mode, a photoscanner detects the mark during a constant speed web feed period prior to the end of the available time and actuates the web feed accordingly.

  • Patent number: 4413983
    Abstract: An improved multi-station machine is disclosed for assembling ring-type closures from generally cylindrical paperboard cylinders and generally circular paperboard discs. The machine employs a rotatable dial plate, carrying eight mandrels and an improved ring clamping system, which dial plate is incrementally rotated by an automatic indexer assembly relative to the various operating stations which consist of a ring feed station, a disc feed station, an adhesive dispensing station, a curling station, a grooving station and a closure ejecting station. Means are provided for controlling the operation of the various stations so that they operate in substantial synchronism with one another and with the rotatable dial plate. The improved disc feed station automatically feeds the lowermost disc from a stack of discs to a position over a ring on the dial plate and simultaneously forms a peripheral skirt on the disc and positions it in an open end of the ring.

Values representing the stages of the machine in its cycle are generated as the machine progresses through a cycle, the values being determined by the actual stage of the machine independently of time. Starting and stopping points in the cycle for at least one of the functions of the machine is preset in terms of the generated values. The generated values are compared with the preset starting and stopping point values. The machine function is initiated and maintained when the generated values are greater than the preset starting point value but are less than the preset stopping point value and the function is stopped when the generated values equal or are greater than the preset stopping point value. Apparatus and method for computing starting and stopping points for an eyespot window using only a single set of delay switches is also disclosed.
