With Tape-control Means Patents (Class 266/59)
  • Patent number: 8865056
    Abstract: A bevel head apparatus includes tilt, rotation, and vertical positioning with a cutting torch of a numerically controlled plate cutting machine. The apparatus has a back panel that attaches to the cutting machine and provides vertical movement of the cutting torch, a drive box coupled with the back panel houses electronics and mechanical components, an arm coupled to the drive box provides rotational movement of the cutting torch, and a pantograph coupled with the arm provides tilt movement to the cutting torch attached to the pantograph. Tilt, rotation, and vertical positioning of the cutting torch is controlled by the electronics and mechanical components. The bevel head apparatus also include a laser for measuring distance to determine and control a height of the cutting torch above the flat plate.

  • Patent number: 4449699
    Abstract: A method of controlling an operation of a copycutting apparatus including a tracer for tracing automatically a pattern and a cutting gas torch interconnected to the tracer in a given relationship. Prior to the actual working, the tracer is manually moved with respect to the pattern along a given path and stores coordinates of operational points such as a piercing point, a copy start point, a copy end point, an intermediate point, a slow down point, etc. During the actual working the stored coordinates are readout to control the movement of the tracer in such a manner that until the tracer does not reach a copy start point the copying apparatus is set in a position setting mode in which the tracer is moved under the control of the readout coordinates. After the tracer has reached the copy start point the copying apparatus is switched into a copying mode in which the movement of tracer along the pattern is controlled by detecting the pattern.

  • Patent number: 4450014
    Abstract: A method of controlling the operation of a copying apparatus which includes a tracer for tracing automatically a contour of a pattern to be copied and a working machine arranged in conjunction with the tracer in a given relationship is disclosed. At first, the tracer is moved manually with respect to the pattern to be traced to detect point data such as a working start point, a copy start point and a copy end point, and then automatically moved along the contour of the pattern to detect pattern data, while the working operation is performed. Next, the thus detected point and pattern data are stored in a cassette tape. Therefore, in case of performing the repetitive working operation for the same pattern, since the working operation can be performed in accordance with the data read out of the cassette tape, the required working operation can be effected in a simple and rapid manner.

  • Patent number: 4349182
    Abstract: Apparatus for cutting a metal workpiece including pipe in any desired shape and in a cutting cycle governed by a numerical controller having a plurality of separate output control signal channels. The apparatus is highly versatile and automatically operable to cut any preselected contour in accordance with control or program instructions carried on a control tape. In an illustrative embodiment of the cutting apparatus, a metal cutting torch is supported on a first support and the workpiece to be cut is mounted on a second support so arranged relative to the first support that the relative movement between the workpiece and the torch allows a cut to be made along X and Y axes at right angles to one another. The cutting torch is power driven about its own longitudinal or W axis by a reversible motor and is power driven about a fourth or Z axis to vary the bevel of the cut.
