Description

  The present invention relates to a PTP sheet transport apparatus that faces two PTP sheets supplied from an upstream transport path and transports them to a downstream transport path.

  In recent years, PTP (press-through package) that can push out tablets contained in pockets with fingers is generally used for packaging of tablets, etc., and a single sheet is provided with a plurality of pockets. Is called a PTP sheet. In this PTP sheet, since a plurality of pockets constitute convex portions, simply stacking them becomes bulky and inconvenient for storage and transportation.

Therefore, conventionally, by using a conveying device as disclosed in Japanese Patent No. 2597533 (Patent Document 1), a pair of PTPs in which the convex portions of the other PTP sheet are arranged between the convex portions of one PTP sheet. Sheets were prepared, and the necessary number of sheets were stacked and shipped.
Japanese Patent No. 2597533

  In the conventional conveyance device (Patent Document 1), the lift for distributing the PTP sheet to the upper and lower guide plates and the reversing device for reversing the PTP sheet are separately provided at different positions on the conveyance line. Was too long. Further, since the reversing device is provided so as to extend in a direction orthogonal to the longitudinal direction of the transport line, the reversing device cannot be accommodated within the width of the transport path, and the maximum width of the transport line becomes too wide. It was. Therefore, it is necessary to secure a wide installation space for the entire transfer line, and it is difficult to meet the demand for narrowing the installation space.

  Therefore, a main object of the present invention is to provide a PTP sheet conveying apparatus that can reduce the installation space of the entire conveying line.
