Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fabric folding device that creates three strong and reliable linear creases in a fabric.

In this specification, "folding the fabric in four" refers to folding both ends of the fabric folded in a U-shape further inward into an inverted U-shape, as shown in Figure 4A. In order to
・As shown in Figure 4-B, it is necessary to create three strong linear creases in the fabric.

Such four-folded fabric is used for the placket sewn to the front body, pocket openings, cuffs, etc.

"Tri-fold" creates two strong and reliable linear creases in the fabric.
Regarding the device, Japanese Patent Application Laid-Open No. 5083589 discloses the following.

In other words, a fixed heated press plate with both sides as press surfaces,
A press plate device is composed of two movable heating press plates that are driven forward and backward so as to be in close contact with each other on both sides of the press plate device. An elevating member device is provided, which includes a fabric pressing device that elastically presses the fabric portion on the fixed heating press plate, and a two-plate blade that presses and bends the fabric portion that corresponds to the gap between each press plate. Two strong creases are obtained by pinching the crease-forming portion, which is pushed and bent by a blade while being pressed by a fabric presser, with each press plate.

However, the above-mentioned gazette does not mention anything about quarto-folding.

The inventor found that it would be very difficult to obtain the three creases shown in Figure 4-B at the same time, but it would be relatively difficult to obtain the three creases shown in Figure 4-B. I came up with an easy solution.

Therefore, the purpose of this invention is to make two points at the beginning.
It can be said that the object of the present invention is to provide a fabric folding device that can continue to fold the remaining fold.

A stepped hole 22 is formed in the first holder 21 so that the first
The rod 24 of the fabric presser foot 23 and the head 2 at the upper end of the rod 24
5 are slidably inserted into each other, and a spring 26 surrounding the rod 24 is interposed between the lower surface of the first holder 21 and the upper surface of the first fabric presser foot 23, so that the lowering due to the operation of the first cylinder 17 At times, even after the upper surface of the fixed heating press plate 4 contacts the first fabric presser foot 23, the head 25 is pushed up and can be lowered until it collides with the lifting plate 19, so that elastic pressing is possible. There is.

The first holder 21 is also fitted into the gap between the fixed heated press plate 4 and the first movable heated press plate 6 and the gap between the fixed heated press plate 4 and the second movable heated press plate 9, respectively. The first and second fabric pushing blades 27 and 28 are attached.

If the above is called the first elevating member device 29, it is not much different from the one described in the above-mentioned publication.

However, in the present invention, the second elevating member device 30 as described below is provided independently of the first elevating member device 29, or as in the illustrated example, two supports 31 are attached to the first elevating plate 19. It is installed on a base plate 32 that is installed vertically.

That is, a second cylinder 33 is attached to the base plate 32, a second elevating plate 35 is attached to the cylinder rond end 34 extending through the base plate 32, and the elevating plate 35 is provided with a metal plate disposed below the iron plate. An adjusting means 37 is attached which can freely adjust the position of the second holder 36 in the vertical direction.

A stepped hole 38 is formed in the second holder 36 so that a second
The rod 40 of the fabric presser foot 39 and the head 4 at the upper end of the rod 40
1 are slidably inserted into each other, and a spring 42 surrounding the rod 40 is interposed between the lower surface of the second holder 36 and the upper surface of the second fabric presser 39. When the upper surface of the second movable heatable press plate 9 and the second
Even after contact with the fabric presser foot 39, the head 41 is pushed up and can be lowered until it collides with the elevating plate 35, so that it can be suppressed in an elastic manner.

Also attached to the second holder 36 is a third blade 43 for pushing a third cloth, which can be fitted into the gap between the second and third movable heating press plates 9, 11.

That is, with the new installation of the 20th movable heating press plate 9, the second elevating member device 30 is further provided outside the first elevating member device 29.

The above-mentioned adjusting means 20, 37 are both blades 27.2.
8.43, if you convert it into cash, the interval between the two creases in Figure 4-B is 1. It is possible to change and modify l' as appropriate.

In the configuration in which the first and second elevating member devices 29, 30 are lowered simultaneously, the third blade 43 is positioned slightly above the first and second blades 27, 28, and the third blade 43 is positioned slightly above the first and second blades 27, 28.
, while the second blades 27 and 28 push and bend the fabric, the third blade
However, when the first and second elevating member devices 29, 30 are independent, such consideration is not necessary.

The present invention is basically the same as that described in the above-mentioned publication in that it includes a timer and a relay circuit (both not shown) that operate the cylinder and pusher in a predetermined order by turning on the switch 44. .

That is, first, the first cylinder 17 is actuated to start lowering the first holder 21, and the lowering continues even after the first fabric presser foot 23 presses the portion of the fabric that contacts the upper surface of the fixed heating press plate 4. , the first and second blades 27 and 28 are fixed heating press plate 4 and first and second movable heating press plate 6,
The lowering step is completed when a predetermined length has entered the gap between 9 and 9, and thereby the two crease forming portions can be bent.

(See Figure 5-B), then switch the function of the first cylinder 17 to raise the first holder 21, and bring the first blade 27 and second blade 28 to a position slightly out of the gap. Stop it once (at this time, the first fabric presser foot 2
The pressing of the fabric in step 3 continues.

), then the operation of the first and second pushers 5 and 7 is started, and the first and second pushers are applied to both press surfaces of the fixed heated press plate 4.
The moving heating press plates 6 and 9 are brought into close contact with each other (thereby, the two crease forming portions are iron-pressed).

(See Figure 5-C). Up to this point, the process is the same as in the case of horizontal folding, but in the present invention, the second cylinder 33 is continuously operated to start lowering the second holder 36, and the second fabric presser foot 3
9, the third blade 43 continues to descend after pressing the fabric portion that is on the upper surface of the second moving hot press plate 9, and the third blade 43 is inserted into the gap between the second and third moving hot press plates 9, 11 by a predetermined length. The lowering step is completed at the point where it has entered, and the remaining crease forming portion can be bent.

(See Figure 5-D), then switch the function of the second cylinder 33 to raise the second holder 36, and stop once when the third blade 43 reaches a position slightly out of the gap (at this time, The pressing of the fabric by the second fabric presser foot 39 continues (-).

), then the operation of the third pusher 10 is started to bring the third movable heated press plate 11 into close contact with the pressing surface of the second movable heated press plate 9 (thereby, the ironing of the remaining crease forming portion is Pressing is performed.

(See Figure 5-E).

After a suitable period of time, each pusher and cylinder returns to its starting position, thus completing the cycle.

In front of the press plate device 10, there are a sliding plate 45 that slides the fabric onto the device 1, and a presser frame device 46 that presses down the edge of the fold so that it does not lift up when forming the fold. is slightly lifted due to the action of the cylinder 48 when the fabric is fed.

Further, on the back side of the press plate device 1, a ruler plate 49 is provided which is adjustable in the front and back direction and is positioned by coming into contact with the front edge of the supplied fabric.

The fabric is designated by 50. As can be seen from the above description, the present invention provides the second and third movable hot press plates 9, 11.
Since the third pusher 10 and the third pusher 10 are provided on the movable plate 8, the fixed heated press plate 4 and the first and second movable heated press plates 6,
9 and the first elevating member device 29 to press the two strong and reliable straight creases, the preparatory work for tightening the remaining crease is automatically completed. This is extremely advantageous in that the process can then proceed to the step of tightening the remaining one strong and reliable linear crease using the second elevating member device 30.
