摘要:
A curve tracer comprising: an optical tracer head for scanning a line having at least a substantial transverse component and at least one marking on the line, with a predetermined scanning speed. The head is moved along the line at a speed substantially lower than the scanning speed. There is a control unit for controlling the movement including an integrator, means for feeding the integrator with a voltage proportional to the speed of the tracer head, and means for supplying a signal proportional to the distance travelled by the tracer head when the head moves over the marking.

A numerical control device inputs a machining program to control an operation of a machine tool and outputs feedback data obtained as a result of the operation of the machine tool. The numerical control device includes a machining-program analysis unit that analyzes the machining program having a machining shape command to which a mark or a specific program command is attached and that outputs a marking instruction; a delay unit that delays the marking instruction until the feedback data indicating a result of an operation of the machine tool based on the machining shape command is obtained; and a feedback-data output unit that, when having detected the feedback data and the delayed marking instruction, executes, onto the feedback data, marking corresponding to the mark or the specific program command attached to the machining shape command and outputs the feedback data.
摘要:
Retarding markings are provided alongside a linear pattern to be cut out by an automatic device guided by a photoelectric scanner. The markings are disposed a short distance ahead of the changes in direction of the pattern line, which is greater than the resultant decelerating path of the advance motors from the original faster advance speed to the resultant slower advance speed. A timing circuit initiates the change in advance speed after the retarding mark is detected and a second timing circuit changes the overhang of the line-scanning photocells from an initial greater magnitude to the lesser required magnitude correspond to the slower advance speed. Acceleration marks may also be provided after directional changes in the pattern to accelerate the advance speed back to the original advance speed after the changes in directions are accomplished. A third timing circuit is then provided to subsequently increase the advance speed and overhang of the photoelectric cells ahead of the axis of rotation of the scanning head back to their original magnitude.

摘要:
An assembly carrying vehicle running control system, includes a plurality of assembly carrying vehicles, a control apparatus, and a plurality of access points connected with said control apparatus and provided for said plurality of assembly carrying vehicles. Each of the plurality of access points has a communication area. When each of the plurality of assembly carrying vehicles is individually in the communication area of a currently communicating access point of the plurality of access points, the assembly carrying vehicle transmits an operation status data indicative of an operation status to the control apparatus through the currently communicating access point. The control apparatus determines an operation control instruction based on the operation status data to transmit to the assembly carrying vehicle. The assembly carrying vehicle receives the operation control instruction from the control apparatus through the currently communicating access point such that an operation of the assembly carrying vehicle is controlled based on the operation control instruction.
摘要:
An optical pattern tracer is disclosed, of the circular scanning type. The interception of the pattern by the scan produces electrical outputs which are reduced to numerical values representative of their time of occurrence with reference to the scanning circle. The numbers derived and the nature of the signal generated are then processed to indicate the direction of the pattern, presence or absence of command marks and combined with other reference inputs, such as kerf and direction of tracing used to control a drive mechanism to move the tracer around the pattern.
