Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for mechanically obtaining pocket edges that are sewn to opening edges of box pockets, etc., for example in suits and women's clothing. Regarding the box pocket edge automatic folding machine.

[Conventional technology and its problems]

Conventionally, when manufacturing this type of Pokeno H&, each of the above-mentioned side edges of the box fabric, which has a dogleg edge on one side and a sloped edge on the other side, is set to a constant value, as shown in Figure 5 (a). The method was to fold it back at the width, fold it in half along the center line, and press it (see the same figure (opening)), but the folding motion of the above procedure could be mechanized. The current situation is that it has become extremely complex and that until now it has all been done manually.

Therefore, not only is the work of folding the box fabric inefficient, but also it takes time to process the excess fabric that occurs in the center, especially when folding the edge of the dogleg, and uneven thickness tends to occur in the core area. The problem was that the work required considerable skill.

[Means for solving problems]

Therefore, the automatic box folding machine of the present invention is provided with a movable base plate that maintains a constant interval in opposition to the fixed plywood, and a press plate that can reciprocate a certain amount directly below the movable base plate, while the above-mentioned Two front guide plates operate on both sides of the edge fabric placed with their center lines aligned on the grooves formed by both base plates, and a rear guide plate and the front guide plate operate to straddle the edge fabric. An auxiliary guide plate that can be moved differentially with one of the guide plates is provided,
Furthermore, a front presser plate that moves separately from one side of the front guide plate and a rear presser plate that moves on the rear guide plate are arranged respectively, and a folding plate that faces the groove and is movable up and down the premises is provided. The above-mentioned problem has been solved by providing the above-mentioned devices and making them work together in a fixed order.

[For production]

The present invention has the effect of automatically obtaining box-sharp edges and edges by continuously performing the folding of both side edges of the knotted fabric, folding the top and bottom, and pressing with one machine. be.

〔Example〕

Hereinafter, the structure will be described in more detail based on one embodiment shown in the drawings. ＼A movable base plate elastically actuated by a spring 3, in which a groove 4 is formed by both base plates 1 and 2, and
Directly below the movable base plate 2, a press plate 6 that can be reciprocated by a certain amount using, for example, an air cylinder 5 is installed, and a buffer plate 7 made of silicone rubber or the like for absorbing pressing unevenness is provided on the opposing surface of the fixed base plate. is displayed.

Note that, like the movable base plate 2, the press plate 6 forms a4 while maintaining a constant distance from the buffer plate 7, and is elastically expandable via a spring 8.

On the other hand, 9.9゛ is a front guide plate with a front edge shape corresponding to the box fabric (AI dogleg edge (a+)) placed on the groove 4 of the base plate with its center line aligned, This is a rear guide plate whose rear edge is shaped to match the sloping edge (bl) of the box material.

To explain the relative operations of the respective guide plates 9, 9', and 10, for example, first, one of the front guide plates 9 and the rear guide plate 10 operate, and the front guide plate 9 folds a certain amount. Move to the center of the dogleg edge of the box fabric, leaving the allowance, and
The rear guide plate 10 straddles the box material and its inclined edge (b
), and at the same time the other front guide plate 9' is moved down and moved down to join with the front guide plate 9 on the center line of the box material. (See Fig. 3 A)) On the other hand, the boxes 11 and 11 are arranged in parallel at a constant interval across the groove 4, and This is a front presser that moves separately from one side of the guide plates 9 and 9'', and one of the front pressers 11 operates to press the box fabric along the front edge of the front guide plate 9. After folding back only half the edge of the letter KM fal (see figure (b)), the auxiliary guide plate 12 differentially moves and descends, and the excess piece of box fabric overlaps the tip of the front guide plate 9'. is pressed down (see Figure 1), and the other front holding plate 11 moves on its upper surface, thereby folding back the remaining half of the dogleg edge (see Figure 1). ).

During this time, a rear presser plate 13, which is provided across the a4 and has a notch 13'' corresponding to the groove 4 on the negative side edge, moves on the rear guide plate in opposition to the front presser plate, and presses the back of the box fabric. The beveled edge at the end (where the bl is folded back).

Next, after the front guide plate 9' and the front guide plate 9 together with the auxiliary guide plate 12 have been moved by a certain amount, that is, to a position past the front holding plates 11 and 11' (see figure (E)), the above-mentioned The front guide plate 9' and the auxiliary guide plate 12 are stirred and raised, and the front guide plate 9 and the rear guide plate 10 are both returned to their original positions shown in FIG. The box fabric holder is fixed on the base plate by the above-mentioned front and rear presser plates 11, 11' and 13.

(Refer to the same figure) Furthermore, at this time, a plywood groove 4 is placed in the center of each of the above-mentioned holding plates.
Since a gap corresponding to the above groove is secured, by lowering the folding plate 14 which is movable up and down facing above the groove, the box material is folded in two and pushed into the groove. .

(See Figure 4) A) 10)) In this case, the movable base plate 2 and press plate 6 are elastically expanded by the springs 3 and 8, and the box fabric prisoner is held between the grooves of the fixed base plate. Therefore, when the box fabric prisoner is pushed down to the position of the press plate 6, the folding plate 14 rises and at the same time the air cylinder 5 is activated to press the box fabric prisoner. After tightening and completing the blur 7H& (see Fig. 4 (c)), the press plate is moved back to drop it out of the machine.

Further, during the above-mentioned pressing process, a new box fabric is set on the plywood, or a folding process similar to the above-mentioned folding process is performed one after another on the plywood.

The front and rear guide plates and presser plates mentioned above are all equipped with springs (
(not shown) is pressed against the plywood at a constant pressure.

〔Effect of the invention〕

The automatic folding machine of the present invention having the above configuration can completely mechanize the conventional manual folding work.
This method has the extremely remarkable advantage of being able to efficiently obtain a homogeneous box pocket edge with no uneven thickness without requiring any skill, and improving productivity by more than 10 times at once. .
