Claims (1)

[Scope of Claim for Utility Model Registration] (1) A PTP sheet after forming a pocket for accommodating an article to be packaged is placed along a straight path between a seal roller on the drive side and a tension roller on the driven side for sealing the pocket. , a means for conveying the PTP sheet with its pocket facing downward; a filling drum arranged so that its outer periphery having a recess for accommodating the packaged articles is in contact with the upper surface of the PTP sheet conveyed along the straight path; and a filling drum adapted to the outer periphery of the filling drum. In the apparatus, the device has a guide chute arranged with a slight gap on the outer periphery of the side of the filling drum, and a packaged article storage chute arranged above the filling drum, in relation to the filling drum. means for rotating and generating a clock pulse signal for counting; a sensor for detecting the pocket of the PTP sheet by the beginning of the tip of the bulge and generating a first gate signal; and rotation of the seal roller. Relatedly, means for generating a second gating signal, for counting the clock pulse signal, the counting period of which is initiated by one of the first and second gating signals, and the counting period is initiated by one of the first and second gating signals; a counting means adjusted to be completed by; comparing the clock pulse signal count with a value predetermined according to the position and size of the pocket;
means for generating a control signal according to the comparison result;
A pocket positioning device for a PTP machine, comprising: means for adjusting the tension applied to the PTP sheet conveyed along the straight path in response to the control signal. (2) The PTP sheet is wound between the seal roller and the tension roller, and the PTP sheet is wrapped between the seal roller and the tension roller.
2. The method according to claim 1, wherein the means for adjusting the tension applied to the P sheet is a powder brake provided on the tension roller, and the powder brake is adjusted by the current value of the control signal. Pocket alignment device for PTP machine. (3) The PT according to claim 1, wherein the device for generating the clock pulse is a rotary encoder.
P-machine pocket alignment device. (4) Claim in which the sensor that generates the first gate signal is an optical sensor comprising a pair of light emitters and receivers, and detects the pocket of the PTP sheet by the beginning of the tip of the bulge. A pocket positioning device for a PTP machine according to item 1. (5) Pocket positioning of a PTP machine according to claim 1, wherein the means for generating the second gate signal is an angle indicator attached to the seal roller or a member that rotates in relation to the seal roller. Device.
