EXAMPLES Examples of the method for manufacturing a handbag according to the present invention will be described in detail below.

The bag B is at a stage separately manufactured by a bag-making machine, and is a foldable left and right that connects the bottom surface 1, front and rear surfaces 2 and 3 standing up and down, and the left and right surfaces of the both surfaces 2 and 3. It has a gusset portion 4 and 5 and has an opening 6 at the top (FIG. 1C). This bag B is shown in FIG.
It is supplied in a flattened state as shown in FIG.

The first step is the first step for opening the opening 6 back and forth by the suction cup mechanism 21 for adhering to the front and rear surfaces of the supplied flat bag B to extend the gussets 4 and 5 (see FIG. 1 ( b), Figure 2).

The second step is a step in which the gusset portions 4 and 5 of the opening 6 opened back and forth are sandwiched by the holding member 22 to open the opening 6 left and right (FIG. 1).
(C), FIG. 3).

The left and right gussets 4 and 5 are preliminarily formed with folds 7 for orderly bending the opening edges. The fold line 7 coincides with a position where the opening edge of the bag body is bent by a reinforcement piece to be described later, and the holding member 22 is held in the town width direction.
It is formed at the same time as being sandwiched by the component pieces 22a and 22b (FIG. 4). Further, the bottom spreading plate 23 is pressed against the bottom surface 1 from the opening 6 by the elevator, and the bag body B is completely opened like a saw.

Third step: A bottom plate 8 is inserted into the bag body through the openings 6 which are widened in the front-rear direction and the left-right direction. The bottom plates 8 are picked up one by one from the stack position by the suction device 24 and pushed down to the bottom surface 1 by the elevator (FIGS. 1D and 5). The opening 6 is the bottom plate 8
Is expanded from the inside of the gusset portions 4 and 5 by the opening plate 25 until it is placed on the bottom surface 1.

Fourth step is a step of attaching the reinforcing piece 9 along the opening edge of the bag B (FIG. 1 (e), FIG. 6). The reinforcing piece 9 has a vertical width and a length required for a perforation interval for attaching the brace, but the illustrated example has a length such that the central portion of the opening edge can be reinforced over at least half the length. The vertical width of the reinforcing piece 9 is substantially equal to the width of the upper end portion of the bag B along the opening 6 which is bent downward, and the lower side of the attached reinforcing piece 9 is substantially aligned with the position of the folding line 10 (FIG. 6).
(B)).

Further, the position of the fold line 10 coincides with the fold line 7 of the gusset portions 4 and 5 provided in the previous step.
Like the bottom plate 8, a normal thick plate is used for the reinforcing piece 9, and is bonded to the inside of the upper end of the bag opening 6 with an adhesive. Two
6 is an opening plate, which pushes the gussets 4 and 5 outwards left and right to open the opening 6
Is open.

Fifth step is a step of bending the upper end of the bag opening 6 to fold the gusset portions 4 and 5 inward to form the attachment edge of the carrying hand (FIG. 1 (f), FIGS. 7 to 8). .

Since the gussets 4 and 5 of the opening 6 have the fold line 7 formed in the second step, the upper end of the gusset part is bent from the outer side to the inner side by the bending member 27 at the boundary.

Sixth step The front and rear surfaces 2, 3 of the bag B are bent inward with the lower side of the reinforcing piece 9 as a ruler to complete the entire circumference of the upper end of the bag (FIG. 1 (g), FIG. 8). ~ 9).

The folding member 27 in use in the previous step 5 is
When the upper ends of the bag body B gussets 4 and 5 are actuated so as to be bent inward, and at the same time moved to the left and right, and when the gussets 4 and 5 are pulled outward in the left and right directions, both front and rear surfaces 2 and 3 are also pulled inward. So, after pulling in, both front and back sides 2, 3
The upper end of the opening 6 is reinforced by pushing the pushing plate 28.
The lower side is used as a boundary and is bent following the bending of the gusset portions 4 and 5, and the entire circumference is turned inward.

At this point, two bag members are overlapped at the upper end of the opening 6, and the reinforcing member 9 is sandwiched between them in the front and rear surfaces 2 and 3, respectively, so that a triple layer is formed in the new opening 6 '. A mounting edge 11 is formed that overlaps the. It is not necessary to bond the upper end of the opening 6 bent inward and the inside of the bag body.

When the mounting edge 11 is completed, the pushing plate 28,
A sandwiching plate 29 is also interposed between 28 to clean the fold line and arrange a new opening 6 '. In this way, the center of the gussets 4 and 5 is pulled outward to form a straight line, thereby completing an orderly fold (FIG. 9).

Seventh Step The gussets 4 and 5 pulled outward as shown by the chain line in FIG. 10 (a) in the previous step are opened at a right angle by the opening plate 30, and are inwardly bent by the re-bending member 31 from the outside. This is the step of re-bending (FIG. 1 (h), FIG. 10).

Eighth step This is a step of punching the mounting port 12 of the carrying hand on the carrying hand mounting edge 11. (FIG. 1 (i), FIG. 11). The opening 6'of the bag body B is kept at a constant opening by the opening member 32, the opening member 32 lifts the bag body B, and the punching machine 33 descends to the left and right positions of the attachment edges 11 of the front and rear both sides 2, 3. To form a punch hole (see FIG. 12).

Ninth step This is a step of attaching the carrying hand H (FIG. 1 (j),
(See FIG. 12). The carrier H is a separate line aligner (not shown).
Is previously bent into the inverted U shape by the hand 34 and carried to the bag body B. The carrying hand H is planned to have a fitting type attachment structure shown in FIG. 13, but the present invention is not limited to this. The point is that the protrusions m and the fitting holes n of the fitting pieces K and L are essential. As long as it has The specific shape does not matter.

Tenth step In the step of folding the bottom of the handbag HB manufactured as described above and closing the opening 6'to flatten it again (FIG. 1 (k)) so that it can be sent out of the process for packing or the like. is there.

[0023]

Since the present invention is constructed as described above, the upper end portion along the opening of the bag of the semi-finished product is bent inward to form a reinforced mounting edge, and at the same time, the handle mounting edge A series of operations of perforating the attachment port in the part and finally attaching the carrying bag can be automatically and mechanically performed, and therefore, the carrying bag can be manufactured efficiently and with high product accuracy.
