Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a skirt pressing method and a pressing device.

Normally, when pressing a skirt with pleats such as pleats, it is desired that all the pleats be pressed in a straight line perpendicular to the waist. Conventionally, the skirt is passed through a horizontal mat, and the skirt is rotated one after another to press each pleat one by one. However, the method of pressing each pleat one by one not only takes an hour and is inefficient, but also requires considerable skill to align all the pleats in a straight line perpendicular to the waist. This is because the skirt has a bulge around the waist, and if the pleats were simply arranged in a straight line, they would tend to form a diagonal straight line from the head.

An object of the present invention is to provide a pressing method and a pressing device that efficiently obtain good pleat linearity without requiring much skill.

In the present invention, instead of pressing each pleat one by one, all the pleats within an area corresponding to approximately one side of the skirt are pressed at once to shorten the pressing work.

In this case, in order to ensure that all the folds in the plane are aligned naturally and approximately correctly, a vertical dummy (middle row) is used, the head of the skirt is fixed to the top of the dummy, and the skirt is suspended. Correct the defective parts and maintain the condition. In addition, when performing this pleat removal work, that is, the work of aligning all the pleats, in order to enlarge the work space and make the pleat removal work easier, place the dummies diagonally so that the skirt surface to be set is on the top side. Tilt it and hold it still. In order to increase the work efficiency of the rough pleat removal work, during the pleat removal work,
Suction the skirt with air from inside dummy 1,
Attach the folded surface of the skirt to the surface of the dummy.

After removing the pleats from the skirt, turn the dummy to the other side so that the side with the pleats removed faces downward, press it against the lower mirror on the other side, and press the skirt while tilting it diagonally. do.

During the above-mentioned pressing process, when looking at the upper side of the dummy, the other side of the skirt stands still in an oblique state that makes it easy to remove pleats. Therefore, with respect to the opposite side of the dummies, pleats on the other side of the skirt can be removed in the same manner as described above, in parallel with the above-mentioned pressing, and depending on the circumstances, after the above-mentioned pressing is completed. Therefore, by installing lower mirrors on both sides of the dummies, after pressing one side of the skirt, the dummies are turned to the opposite side so that the skirt side with the pleats removed is facing downwards, and the lower mirrors of iS2 are placed. It is also possible to press the other side of the skirt by pressing it together.

Hereinafter, the present invention will be described with reference to an illustrated embodiment.

In Fig. 11 and Fig. 2, 10 is a vertical middle stage (
(dummies), 21 and 22 are lower mirrors provided on both sides of the middle stage 1O in an upwardly open state, and 30 is a clamp device provided on the middle stage 10 for fixing the head portion of the skirt to be pressed and suspending the skirt. FBl and PH2 indicate power on/off switches, and PH1 indicates a start switch.

The middle stage IO consists of a middle stage main body 11 in the form of a flared hem, and legs 12 and 12' provided on both side edges of the base of the middle stage main body, and the lower ends of these legs are pivotally supported on the shaft 2 at the bottom of the machine frame. ing. The middle main body 11 is sloped in two tiers on the sides in order to match the shape of the skirt suspended on the clamp device 30 and to facilitate insertion of the skirt. The middle leg 12 is connected to a middle drive device, which drives the lower mirror 21.2.
It can tilt in two directions (left and right directions in the figure). In this embodiment, an air cylinder 3 is used as the middle drive device, and is pivotally attached to the tip of a piston rod 4 via a pivot shaft 5.

On the other hand, the lower mirrors 21 and 22 are the vertical frame IA of the machine frame L, respectively.
Arm pairs 6 and 6”, 7 and 7 protrude inward from IB
” is supported on both sides so as to be able to swing around shafts 23 and 24, and the back surface of the lower mirror 21 is inserted between the back surface and the tilt machine frame 8.8 degrees. spring 2
5, the back surface of the lower mirror 22 is supported by springs 26 inserted between the back surface and the back surface of the lower mirror 9.9 degrees. That is, the lower mirrors 21 and 22 are not completely fixed to the machine frame, but are allowed to swing to some extent.

In this embodiment, the clamp device 30 includes an inverted-shaped support arm 31 whose lower end is tiltably pivoted to one side of the base of the middle main body 11, and an inwardly expandable support arm 31 suspended from the arm. It is composed of a clamp tool 32.

As can be clearly seen from FIG. 3, the support arm 31 includes a support column 33 having a polygonal vertical hole, and a support rod of a complementary cross section that is inserted into the vertical hole of the support column 33 so as to be able to project from above but not rotate. 34, and a horizontal rod 35 extending from the upper part of the support rod in the direction of the middle stage 10. It is pivotably mounted so that it can be tilted. This support arm 31 is normally given a weak rotational behavior by a spring (not shown) so as to be in the solid line position in FIG. The purpose of configuring this support arm 31 to be tiltable with respect to the middle stage 10 is mainly when fixing the waist of the skirt to the clamp device, by inserting the inwardly expanding clamp tool 32 from directly above the middle stage 10.
This is to make it easier to insert the waist part of the skirt from below into the inwardly expanding clamp tool 32 by shifting it laterally as shown by the broken line in FIG. Further, the purpose of dividing the support arm 31 into a support column 33 and a support rod 34 and making the support rod 34 movable up and down is as follows.
This is mainly to enlarge the space between the clamp tool 32 and the middle stage 10 and facilitate the work when inserting the skirt whose waist part is fixed to the clamp tool 32 into the middle section 3910 from above. In order to restrict the range in which the support rod 34 can move up and down, the support column 33 is provided with a slot 37, from which a pin 341 fixed to the support rod 34 protrudes. Further, a spring 38 is hooked between this pin 341 and a pin 331 fixed to the upper part of the support column 33 so that the support rod 34 can be moved upward with a slight force when installing the skirt.

The internal clamping tool 32 includes a bar member 4o, a knurl 43 suspended from one side of the bar member via a sliding member 41i, and a knurl 44 suspended from the other side of the bar member via a fixing member 42. and a tension spring 45 provided between the sliding member 41 and the support rod 34. Due to this spring 45, the sliding member 41 and hence the knurl 43 are always biased in a direction away from the other knurl 44, and normally remain stationary at the stopper 46 position.

What made it possible to shorten the distance between the knurls 43 and 44 was
The purpose is to allow the two knurlings 43 and 44 to be inserted into the closed loop at the waist of the skirt, regardless of the size of the skirt, and one of the knurlings 44 is fixed in position to facilitate its operation. This is to do so. The two knurlings 43, 44 each have a hanging member 41.
It is attached to 42 with rotation function. Therefore, the clamped skirt can be rotated as necessary to bring the desired surface to the middle surface.

The internal clamping tool 32 is supported at the center of the horizontal bar 40 by a carriage 3/9 that is slidably attached to the horizontal bar 35 of the support arm. The reason why the internal clamping tool 32 is made slidable along the horizontal rod 35 is to enable the center of the skirt, whose waist is fixed to the clamping tool, to be aligned with the center of the middle stage 10.

FIG. 5 shows the front of the middle main body 11, and FIG. 6 shows the cross section.
The middle main body 11 consists of three layers of chambers, with a steam chamber 13 in the center and outer chambers 14, 15 for hot air and vacuum on both sides thereof. The central steam chamber 13 is a space between two wire meshes or two iron plates 131 and 132 with many small holes placed side by side, and the outer chamber 14 and 15 are adjacent to these iron plates 131 and 132 and the outside thereof. Plate material 140 with a large number of small holes.
150. Between the iron plates 131 and 132, connecting portions 133 are provided at various places to prevent explosions. On one side of the base of the middle main body 11, there is a steam outlet 16A passing through the steam chamber 13, and a steam outlet 16B.
However, there are also vacuum connection ports 17A and 17B on both sides of the base of the intermediate trowel body, respectively, which communicate with the outer chambers 14 and 15.
A hot air connection port 18 is provided. Outer chamber 14.1
It is preferable to provide guide portions 18A on both sides of the hot air connection port 18 in the hot air connection port 5 to facilitate the upward movement of air and improve response.

FIG. 7 shows a cross section of the lower mirror 21 (22). Lower mirror 21.2
2 has a steam chamber 27 and a vacuum chamber 28 located on the top side of the iron in contact with the steam chamber 27, as seen in FIG. 27A and 27B are steam inlets and outlets communicating with the steam chamber 27, and 29 is a connecting port of the vacuum chamber 28.

As shown in Figure 4, one machine frame has two blowers 47.4
8, the air outlet 47A of the first blower 47 is open to the air pipe 50, and the air outlet 48A of the second blower 48 is open to the outdoors. Further, the intake port 48B of the second blower is not only connected to the intake pipe 60, but also connected to the intake port 47B of the first blower through another pipe line, and the pipe line is connected to the diaphragm valve (double valve) 49. It is open to the outdoors through. Therefore, by controlling the opening and closing of this double valve 49, the strength of air blowing and air intake can be controlled.

In FIG. 8, each of the air pipes 50 is equipped with a solenoid valve (
Outer chamber 1 of the middle stage lO via hot air valve) 52.53
4.15 are connected to the intake pipe 60 through solenoid valves (vacuum valves) 61 and 62, respectively, to the outer chamber 14.15 of the middle stage lO, and to the solenoid valves (vacuum valves) 6
A vacuum chamber 28 is connected via 3.64. 70 is a steam pipe, to which the steam chamber 13 of the middle stage 1O and the steam chamber 27 of the lower mirror 21, 22 are connected, as well as a solenoid valve (steam valve) 7.
1.72 to the middle outer chamber 14.15. 55 is a drive switching valve for the pressurizing cylinder 3.

Next, the operation of the above device will be explained with reference to FIG. 9 and FIG. 1O.

Initially, the middle stage lO is in the vertical position (
(normal position).

■Removing pleats from the skirt (Fig. 1 θ (A)) First, tilt the clamp device 30 diagonally as shown by the dotted line in Fig. Clamping tool 32 while pulling it to the right in the figure.
Insert the waist of the skirt between the knurls 43 and 44 0
When you release your hand, the action of the spring 45 causes the knurling 43.
44 expands, and the waist of the skirt is fixed to the clamping tool 32.Next, the support rod 34 of the clamping device 30 is pulled up, and the middle stage 10 in the vertical position is stacked on top of each other while the skirt is held inside! ! Insert it into the IO from above and pull down the support rod 34. In this case, if necessary, the skirt is rotated around the knurls 43 and 44 to prevent the zipper or the like of the skirt from coming within the plane of the middle stage 10. Next, by pinching the walnut parts at both ends of the skirt with clips (not shown) and eliminating the walnuts at the waist of the skirt, all the folds in the area facing the press surface of the middle tier 10 hang straight down in a straight line. I'll do what I do. Then, press the start switch FB-3 (Fig. 1).

■ Removing pleats on one side (Fig. 1 θ (B)) When the start switch PB-3 is pressed, a middle trowel drive signal is generated, and the electromagnetic solenoid 5QL4 of the drive switching valve 55
-A (FIG. 8) is ONL, and the middle stage 10 moves to the right due to the action of the pressurizing cylinder 3.

When the middle stage lO rotates 11" to the right, the limit switch LS2 for detecting the right l'" turns on (point b in Figure 10).
, 5QL4-A is turned OFF, and the middle stage 10 stops at an obliquely inclined intermediate position as shown in FIG. 9 CB). At the same time, a steam timer Tl (not shown) is activated, and the steam valve 71 at the middle stage 10 is opened for a certain period of time, for example, 10 seconds, and steam is sent into the left chamber 14 of the middle stage 10. Therefore, the steam is applied to the pleats of the skirt, making it possible to easily straighten the wrinkled pleats. When the operation of the steam timer TI is completed, a rest timer T2 (not shown) is activated and waits for the vacuum valve 61 to open for a certain period of time, for example, 10 seconds. This is because the heated skirt is left alone and waits until the temperature drops to a level where the worker can touch it. When the operation of the rest timer T2 ends, the vacuum valve 61 belonging to the left chamber 14 of the middle stage 10 is opened, and the skirt is sucked to the left side of the middle stage 10. Therefore, the folds of the skirt are not disturbed,
It is possible to easily remove pleats from the skirt. In this pleat removal process, the vacuum valve 61 is energized by
It can be shut off at will using a foot switch (not shown), making the crease removal work easier.

■ Pressing one side and removing creases from the other side (Fig. 10 (C)) After removing creases, press the start switch PB3 again, this time electromagnetic solenoid 5OL4-B of the drive switching valve 55.
(FIG. 8) is ONL, and the middle stage lO moves to the left due to the action of the application cylinder 3. When the middle stage lO rotates 15'' to the left, the middle stage lO comes into contact with the lower!!21 and enters the pressurized state, and the limit switch LS3 for left end detection turns on (point e in Fig. 1θ). The vacuum valve 61 in the left chamber of the bell lO is closed. When LS3 is turned on, the steam timer T1 on the left side of the middle stage and the steam timer T3 (not shown) on the right side of the middle stage are activated at the same time. The steam valve 71 is opened by the timer TI. Steam is then sent into the left chamber 14 of the middle stage 10. Therefore, the skirt is exposed to steam from the inside.

On the other hand, the steam valve 72 on the right side of the middle stage is opened for a certain period of time by the timer T3, and steam is sent into the right chamber 15 of the middle stage 10. This corresponds to pre-processing to remove the pleats on the opposite side of the skirt.

When the timer operation of timer T3 ends, the power supply circuit of timer Tl is forcibly cut off. Therefore, when the middle stage lO is at the left end position, the timer time of the timer T1 cannot be manually extended, and the rest timer T2 is disconnected and becomes irrelevant.

Simultaneously with the end of the timer operation of the timer T3, the timer T4 is activated, and the hot air valve 52 of the left chamber of the middle stage 10 and the vacuum valve 63 of the lower mirror 21 are activated for a certain period of time, for example, 10 seconds.
is opened (point f in Fig. 1θ), so that hot air is blown into the skirt from the inside of the skirt, and at the same time is vacuumed from the lower mirror 21, that is, from the outside of the skirt. When the operation of the timer T4 ends (point g in FIG. 1θ), the hot air valve 52 and the vacuum valve 63 are closed. In this way, sending hot air to the skirt from the left chamber 14 of the middle stage 10 and vacuuming from the lower mirror 21 side at the same time is equivalent to pressing the skirt from the inside. It has the great advantage of not causing so-called hit on the skirt. On the other hand, at the same time as the timer T4 ends, the vacuum valve 62 of the right chamber 15 of the middle stage 1O opens, and the skirt part riding on the upper side of the middle stage 1O is exposed to steam because the time set by the timer T4 has passed since the steam was applied. , the temperature has dropped to the point where you can touch it with your hand. Therefore, as in the case of the intermediate position described above, it is possible to remove pleats for pressing on the remaining one side. In the pleat removal process, the supply of electricity to the vacuum valve 62 can be arbitrarily interrupted by a foot switch (not shown).

[Co., Ltd.] Press on the other side (Fig. 10 (D)) Once the pleats on the remaining side have been removed, turn on the start switch PB3 again.
is pressed (point h in FIG. 10), the electromagnetic solenoid 5QL4-A (FIG. 8) of the drive switching valve 55 turns ON, and the middle stage 10 moves to the right. 5QL4-B is disabled by the condition that the middle stage lO was at the left end before starting and PH1 was pressed. Therefore, the middle stage i0 passes through the intermediate stop position.The middle stage lO moves 15 to the right.
``When rotated, the middle stage 10 comes into contact with the lower mirror 22 and enters a pressurized state, and the limit switch LS4 for detecting the right end turns OFF.
N (point i in Fig. 1θ), thereby closing the vacuum valve 61 in the left chamber of the middle stage IO. Also LS4 is ON
Then, the steam timer T5 (not shown) on the right side of the middle row is activated, and the steam valve 72 is opened for a certain period of time.
Steam is fed into the right chamber 15 of 10. Therefore, steam is applied to the skirt from the inside. Left side ↑In order not to break the completed press state, middle 111
No steam or hot air is sent to the left chamber 14 of 0, and there is no need for a rest period for shaving. (not shown) is activated, and the hot air valve 53 of the right chamber of the middle stage 1O and the vacuum valve 64 of the lower mirror 22 are opened for a certain period of time, for example, 10 seconds (point j in FIG. 10).

Therefore, hot air is blown into the skirt from the inside of the skirt, and at the same time vacuum is applied from the lower mirror 22, that is, from the outside of the skirt, so that a good press without any so-called hit is achieved.

When the operation of the timer T6 ends, the pressing of both sides ends (point in FIG. 1θ). When the operation of timer T6 ends, the hot air valve 53 and the vacuum valve 64 close, and 5QL
At the same time as 4A turns OFF, 5QL4B turns ON, and the middle stage 10 moves to the left. Then, when the stationary position is reached, the LS
I turns ON, and as a result, 5QL4B stops at 0FFL, a normal position. Thus, the l cycle is completed.

As described above, the pressing method of the present invention involves inserting a skirt into a tiltable vertical dummy iron, fixing the waist part of the skirt to the upper part of the dummy iron, and then tilting the dummy iron and keeping it still. Remove the pleats from the skirt while adhering it to the upper surface of the dummy trowel, then turn the dummy trowel to the opposite side so that the side from which the pleats were removed is facing downwards, and place the lower mirror facing diagonally upwards. Since the pleat removal surface of the skirt is pressed by pressing the skirt, even an unskilled person can perform pleat removal and pressing with good straightness on at least one side of the skirt. Re-clamp the skirt so that the other side is on the pressing surface of the dummy trowel and repeat the same operation.
Can press both sides of the skirt.

The equipment for carrying out this method includes a vertical middle stage that can be tilted by a dummy trowel drive device, a clamp device installed above the dummy trowel for hanging the skirt, and a device placed diagonally upward on one side of the dummy trowel. The dummy trowel has a steam chamber and an outer chamber located one step below in contact with the chamber, and the lower trowel has a vacuum chamber formed on the upper side, and a stationary trowel with a dummy trowel installed upright. A control device for the dummy trowel driving device moves the dummy trowel to a tilted position close to the lower mirror, and a press position where it is brought into pressure contact with the lower mirror, vacuums the outer chamber of the dummy trowel at the tilted position, and moves the dummy trowel to a press position. Since it is equipped with an air intake control device that generates hot air in the outer chamber and vacuums the vacuum chamber in the lower mirror at the same time, the skirt is pressed from the back side, making it possible to press with a good, so-called smooth finish. .
