Actuation Of Tool Controlled In Response To Work-sensing Means Patents (Class 83/370)
  • Patent number: 9039002
    Abstract: A sheet post-processing apparatus which is capable of shortening time wasted until actual start of punching and enhancing productivity. A drive unit causes a moving member which has a cam and reciprocates. A punching member is driven by a movement of the cam of the moving member and punches a sheet when the moving member moves forth and moves back. A determination unit determines a type of the sheet. A control unit controls, when a sheet to be punched is to be subjected to a punching process, the drive unit such that the moving member starts moving before conveyance of the sheet to be punched stops, and controls, when the sheet to be punched is to be subjected to the punching process, the drive unit such that timing with which the moving member starts moving is changed based on the determination by the determination unit.

  • Publication number: 20150135921
    Abstract: A continuous tortilla chip cutting system where tortilla carried on a conveyor are continuously divided by a cutting mechanism into pre-cuts for frying into chips. A programmable controller drives a servo motor that moves an upper surface of the conveyor at a known velocity V, and a detector located above the conveyor at a known distance D from the cutting mechanism alerts the controller to the imminent arrival of the tortilla. The controller also controls a servo motor that actuates the cutting mechanism in a stop/start fashion. Based on the detection of the tortilla, the controller drives the servo motor associated with the cutting mechanism at just the right time and at just the right speed so that the cutter mechanism cuts each arriving tortilla into predictable sub-units called “pre-cuts” based on the velocity V of the conveyor belt, the detection of the flat bread unit carried by the conveyor, and the known distance between the moving flat bread unit and the cutter assembly.

  • Patent number: 6978925
    Abstract: A method for creating multiple punch holes during a finishing process of paper sheets and other sheet materials. A highlight of the present invention is the ability to select between at least two configurations of punch holes automatically, without manual adjustment, and “on-the-fly” without interruption of the sheet or paper flow. The perforation method utilizes two rotatable punches set at different angles such that when one intersects the sheet path, the other clears the sheet path. The speed of rotation is controlled such that the non-selected punch intersects the sheet path in a space between pitches.
