が不完全になることが起る。 Therefore, as described in JP-A-58-188264 (see Fig. 7), the applicant welded a bag material band in the transverse direction immediately downstream of a pair of upper and lower clamping type intermittent transfer conveyors. A welding and fusing device for fusing is provided, a bag-like object holder is provided further downstream from this with a slight space, and two pressing members are provided on the upper surface and the upstream end of this holder, which alternately approach and separate from each other. ,
In a state in which the pressing member that approaches and separates from the upper surface is separated from the pedestal and the pressing member at the upstream end is in pressure contact with the pedestal, the intermittent transfer conveyor moves the bag material strip to a predetermined size on the pedestal. The bag material strip is fed onto the table, and during the next intermittent transfer conveyor stop, the vertically movable pressing member is lowered, thereby pressing a part of the bag material strip onto the table and welding it almost simultaneously. Operate the fusing device to weld and cut the bag material band,
The tip part is made into a bag-like object, and the pressing member that was pressing the upstream end of the pedestal is once separated, and the upstream end side of the bag-like object that has just been manufactured is placed on the top surface of the pedestal. We developed a device that repeats the operation of pressing the pressing member against the bag-like object on the pedestal again and then separating the pressing member on the upper surface upward, but since the downstream end of each bag-like object was distorted, During this time, air intervenes, and together with the distortion, the bag-like objects become bulky, and the bags that are sent out until the predetermined number of sheets are reached hit the group of bag-like objects on the pedestal, making it difficult or impossible to organize them afterwards. Alternatively, when a group of bags that has reached a predetermined number is to be clamped all at once at the downstream end, the clamping may become incomplete.

果を有する。(Effects unique to the embodiment) In this embodiment, as described above, the pedestal 1
A horizontal movable pressing member 35 is provided on the upright wall 19 facing the space 14 at the upstream end of the horizontal movable pressing member 30, and alternately presses against the pedestal 15 with the vertical movable pressing member 30. Because they are connected,
There is no fear that the position of the group of bags A stacked on the pedestal 15 will shift, and moreover, the count-up signal of the counter 46, which is a detection device, detects that a predetermined number of bags A are stacked on the pedestal 15. When the vertically movable pressing member 30 is lowered and the pedestal 15 becomes completely horizontal, the clamping tool 40 holds the bags A group at the positions of the notches 18 and 32 of the pedestal 15 and the vertically movable pressing member 30. The compressed downstream end of the bag is securely clamped, and when the vertically movable pressing member 30 is separated, the horizontally movable pressing member 35 is also separated. This has the effect of accurately transporting the A group to the next processing station.
