The restricting member 52 holds the connection panel Mc of the mount M positioned at the mount supply position P in an upright state.

  The collective article G is pushed between the two extended panels Ma and Mb of the mount M, which is positioned in a posture in which the upstream side of the transport is opened and spreads at the mount supply position P along with the feed by the transport bar 16. When the leading edge in the conveying direction comes into contact with the connection panel Mc, the mount M combined with the aggregated article G moves forward. Here, the restricting member 52 disposed on the downstream side of the board supply position P elastically pushes the connecting panel Mc, and the board M that is pushed forward by the collective article G is given movement resistance. Then, the collective article G that is combined with the mount M and pushed by the transport bar 16 moves forward in a state where it is in contact with the connection panel Mc. As a result, the collective article G blocked by the connection panel Mc can be prevented from being moved ahead of the mount M and displaced from the mount M, and the collective article G and the mount M are positioned and combined at an appropriate position. be able to. Further, the second extending panel Mb is brazed along the upper part of the collective article G by pushing the restricting member 52. The mount M and the collective article G combined in this way are pushed by the transport bar 16 of the supply conveyor 10 and fed toward the tubular film formed by the packaging unit W. In the horizontal bag making and filling machine, By performing vertical sealing on the film and horizontal sealing between the aggregate articles G, a pillow package F (see FIG. 7) in which the aggregate articles G and the mount M are combined and packaged can be obtained.

  In this way, since the mount M is positioned at the mount supply position P of the supply conveyor 10 in such a manner that its extended end side extends toward the upstream side of conveyance, when the collective article G is combined with the mount M, the posture of the collective article G They can be combined in a state where they are positioned at predetermined positions on the mount M without disturbing the alignment state. In addition, when the mount M is formed, the folding folds are attached, so that the mount M can be kept in a folded state and can be satisfactorily fed into the cylindrical film together with the collective article G. Further, when the mount M and the collective article G are combined, the collective article G conveyed by the supply conveyor 10 is pressed against the mount M fed from the side of the supply conveyor 10 and positioned, and the collective article G The mount M and the collective article G are combined with each other by the conveying force. Accordingly, it is not necessary to synchronize the transport timing of the collective article G and the mount M, and the collective article G and the mount M are not misaligned with each other, thereby disturbing the posture and alignment state of the collective article G. In addition, the assembled article G can be combined with the mount M and transported well toward the cylindrical film.
