Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in an automatic packaging filling method and apparatus.

The filling method for automatically packaging powders or granules, such as sugar or stomach powder, in a stick-like packaging film is generally to cover a cylindrical chute with a tubular packaging film and vertically feed the film through holes. This involves filling the packaged items through a cylindrical chute in a synchronized manner, followed by thermal welding of the film and cutting of the film.Since all of these operations are performed in the filling section, it can be carried out at high speed and continuously. The problem was that bulk packaging was not possible.

Therefore, in the process of continuously transporting the tubular packaging film across the filling part of the packaged items, the present invention
The object of the present invention is to provide an automatic packaging filling method and device that can increase the filling processing capacity and speed of a filling section by cutting the film and thermally welding the film.

That is, the present invention suctions the tubular packaging film that is continuously conveyed directly below the packaging material filling section with a suction head that moves in the same direction, and at the same time or after this suction, a pair of front and rear film cutters is used. After cutting the suction film to the length of one bag, the suction head was rotated 90 degrees horizontally to stand up the suction film, and the opening at the bottom of the suction film was sealed with heat welding means. In addition, the method is characterized in that the packing chute is lowered to push the packing material into the lower end opening of the adsorption film, and then the packing material is carried into the packing section.

The details of this invention will be explained below with reference to the drawings.

In this case, it is clear that the break point N, which is cut by the following film cutter (7), becomes the cut point N2 of the packaging film unit (41) that is subsequently formed.

Next, as the suction head (8) moves from point B to point B,
It is rotated by 0 degrees (this process is shown in the ?rss diagram), and the nine adsorbed packaging films (41) are erected as shown in Figure 8), and at the same time, the lower heat welding means (9) is activated. The pair of heaters (9oM9b) are closed, and the lower end cdim of the upright packaging film (41) is sandwiched and hot melt is added (Fig. 8-), which is also clear in Figs. 2 and 3. The filling chute (T) descends in this manner and enters the upper end of the packaging film unit (41).

Then, these things sneaked under the weighing table (3o),

In addition, the material to be packaged is supplied to the top surface of the weighing table at the part G in Figures 1 and 2, which is also inward from the moving path F1 in 1c, and the material to be packaged is completely removed (c31). It is clear that a scraping board (42) to which a suitable member (not shown) is fixed is provided in contact with the upper surface of the weighing trowel in order to accommodate a fixed amount of packaging material.The packaging film itself (41) is Thereafter, the receiver passes through the weighing table and moves toward the return point.During this movement, the packaged items stably sink to the inner bottom of the packaging film (41), and even if the packaged items are scattered, Even with such fine powder, by taking a relatively long period of time for the 9th movement from point 8 to point D, it is possible to eliminate the powder biting during the next upper end stop i1+/J operation.Thus, the lower end Immediately before the packaging film jj (body (41)) is sealed and filled with the items to be packaged and reaches the delivery point, the light 1 shot 01 rises and the packaging film IIL body (41) is filled. When it reaches this transfer point DK'', the suction head (8
) is eliminated, and the upper heat welding means c36) passing through the first three-way F2 to the second transfer 6t)) uses its pair of heaters (36aX36b) to attach the filled packaging film alone (4j
), and at the same time the lower heat welding means (9) opens, thus releasing the filled packaging film alone (41).
is drawn into the second movement path F2, and while moving it Qj, the lower end is sealed, and the lower end is sealed at I (point 81.;
It is discharged as packaged products such as <1 (f). Such wrapping operations are performed continuously.

In addition, at point A in FIG. 1, the tubular packaging film (4) to be supplied 11 and It is necessary to pass it between (7o) and (7d). Therefore, in the cutter, as shown in FIGS. 6 and 7, the fixed blade (7a) and the flang member (7c) are fixed to the turntable (5), and the movable blade (7b) and the flang member (
7d) is made to stand up and down around the support shaft (0), and after passing the tubular packaging film (4) through the inverted position shown by the solid line in Figure 6, it is made to stand up and perform clamping and cutter operations. Enter. Therefore, the symbol 9 (44) is the cam trochanter for this raising/lowering σν1 operation, and the symbol (45) in Figure 1 is
