  • Patent number: 6062226
    Abstract: When tobacco shreds continuously supplied while the supply amount thereof is controlled are wrapped continuously with an elongated cigarette paper to form a tobacco rod and the tobacco rod is cut to predetermined lengths to manufacture cigarettes, the filling amount (filling density) of tobacco shreds at every portion in the lengthwise direction of tobacco rod is continuously measured in connection with the wrapping operation of the tobacco rod. The filling amount (momentary value) at every portion of the tobacco rod is compared with threshold values set in advance to detect a local excess filling portion and/or deficient filling portion of the tobacco shreds. This detection result is output in synchronization with the conveying timing of a cigarette having a predetermined length continuously cut from the tobacco rod, by which a cigarette including the local excess filling portion or deficient filling portion of tobacco shreds can be rejected surely.

  • Patent number: 4724429
    Abstract: A system for monitoring each of multiplicity of variables in the operation of a filter rod making machine includes sensors located at various points on the machine. These sensors measure the value of such variable parameters as the width of the tow, the alignment of the wrapping paper, the speed of the rollers and the level of plasticizer. Each measured value is compared against preset limit values in a microprocessor. If a variable is detected to be outside a range of acceptable values, an indication of this fact is displayed on a monitor. In response to this indication, an operator can decide whether to override the limit value or take corrective action. If corrective action is to be taken, the microprocessor causes a diagnostic chart to be displayed. This chart provides the operator with a sequence of troubleshooting steps that can be taken to isolate the source of a possible problem and perhaps correct it before there is a need to arrest the operation of the machine.

  • Patent number: 4373188
    Abstract: Cigarette-rod weight monitoring system in which the signals from a scanner, e.g. a nucleonic device such as Molins "MODIC", are processed and stored in a memory in a digitized form, and the memory contents are used to drive an analog display device. These signals, which represent the individual cigarettes, or short lengths, are accumulated in the memory over a period which is sufficiently long for a statistically significant distribution pattern to be achieved, so that the shape of the distribution curve can be observed to determine whether it is "normal" or whether any skews or other irregularities are present. In addition the accomulated signals can be analyzed in various ways to provide quantitative measurements of overall standard deviation, or effective standard deviation either side of the mean to show whether any "skews" exist. S.D. can be calculated for whole cigarettes or short lengths for different diagnostic purposes.
