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 required 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, one fold
The method of pressing the folds one after another is not only time consuming and 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 are simply arranged in a straight line, they tend to form a straight line diagonally from the waist.

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 trowel is used, and the waist part of the skirt is fixed to the top of the trowel, 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 increase the work space and make the pleat removal work easier, the dummy trowel is placed diagonally so that the skirt surface to be set is on the upper side. Tilt and hold still. Furthermore, in order to improve the work efficiency of the pleat removal work, during the pleat removal work, air is used to suck the skirt from inside the dummy trowel so that the pleat removal surface of the skirt is attracted to the surface of the dummy trowel.

Once the pleats have been removed from the skirt, turn the dummy trowel to the opposite side so that the side from which the pleats were removed is facing downwards, press it against the opponent's lower trowel, and press the skirt while tilting it diagonally. do.

In addition, during the above-mentioned pressing process, looking at the upper side of the dummy trowel, the other side of the skirt stands still in an oblique state that facilitates pleat removal. Therefore,
Regarding the opposite side of the dummy trowel, in parallel with the above pressing, depending on the circumstances, after the above pressing is completed,
The pleats on the other side of the skirt can be removed in the same manner as above. Therefore, by providing lower trowels on both sides of the dummy trowel, after pressing one side of the skirt, the dummy trowel is tilted to the opposite side so that the skirt surface from which pleats have been removed is facing downward, and the second lower trowel is placed on the dummy trowel. It is also possible to press the other side of the skirt.

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

In FIGS. 1 and 2, 10 is a vertical trowel (dummy trowel) that can be tilted around a shaft 2 provided at the bottom of a U-shaped machine frame 1, and 21 and 22 are trowels 1 and 2, respectively.
Lower trowels 30 are provided on both sides of the inner trowel 10 to open diagonally upward, and 30 is a clamp device provided on the middle trowel 10 for fixing the waist portion of the skirt to be pressed and suspending the skirt. PB1 and PB2 are power on/off switches, and PB3 is a start switch.

The middle trowel 10 includes a middle trowel main body 11 with a flared hem, and leg parts 12 and 12' provided on both side edges of the base of the middle trowel main body.
The lower end of this leg is pivotally supported by a shaft 2 at the bottom of the machine frame. The middle trowel main body 11 is connected to a clamp device 30
The sides are sloped in two steps to adapt to the shape of the skirt hung on and to make it easier to insert the skirt. The middle trowel leg part 12 is connected to a middle trowel driving device, and the lower trowel 21, 22 is driven by the middle trowel driving device.
It can be tilted in the direction of (horizontal direction in the figure). In this embodiment, an air cylinder 3 is used as an intermediate trowel driving device, and is pivotally connected to the tip of a piston rod 4 via a pivot shaft 5.

On the other hand, the lower irons 21 and 22 are connected to arm pairs 6 that protrude inward from the vertical frames 1A and 1B of the machine frame 1, respectively.
and 6', 7 and 7' are supported on both sides so as to be able to swing around shafts 23 and 24, and the back surface of the lower iron 21 is connected to the back surface and the tilt machine frame 8,
8', the springs 25 inserted between the
The back surface of the lower trowel 22 is supported by springs 26 inserted between the back surface, the back surface of the lower trowel, and 9, 9', respectively. That is, the lower irons 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 L-shaped support arm 31 whose lower end is pivotably pivoted to one side of the base of the intermediate trowel 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
The support column 33 has a polygonal vertical hole, the support rod 34 has a complementary cross section and is inserted into the vertical hole of the support column 33 so that it can be inserted into the vertical hole from above but cannot be rotated. The lower end of the support column 33 is tiltably pivoted via a shaft 36 to an L metal fitting fixed to the side of the base of the intermediate iron body. This support arm 3
1, a spring (not shown) normally causes the first
The rotational behavior of a weak force is given so that the solid line position in the figure is obtained. The purpose of configuring the support arm 31 to be tiltable with respect to the intermediate trowel 10 is mainly when fixing the waist of the skirt to the clamping device, as shown in FIG. This is to make it easier to insert the waist part of the skirt into the inwardly expanding clamp tool 32 from below by shifting it laterally as shown by the broken line. 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 mainly when inserting the skirt whose waist part is fixed to the clamp tool 32 from above the middle trowel 10. This is to enlarge the space between the clamping tool 32 and the middle trowel 10 and to facilitate the work.
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 hung between this pin 341 and a pin 331 fixed to the upper part of the support column 33 so that the retaining rod 34 can be moved upward with a slight force when installing the skirt. be.

The inwardly expanding clamp tool 32 includes a bar member 40, a knurl 43 suspended from one side of the bar member via a sliding member 41, and a fixing member 4 on the other side of the bar member.
2, 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 thus the knurl 43 are always biased in a direction away from the other knurl 44, and normally remain stationary at the stopper 46.
The reason why the distance between the knurlings 43 and 44 can be shortened is that even if the skirt is of any size, the two knurlings 43 and 44 can be placed within the closed loop at the waist of the skirt, and one The reason why the knurling 44 is fixed in position is to facilitate its operation. two knurling 4
3 and 44 are rotatably attached to hanging members 41 and 42, respectively. Therefore, the clamped skirt can be rotated as necessary to bring the desired surface to the surface of the trowel.

The inwardly expanding clamp 32 is supported at the center of the horizontal bar 40 by a carriage 39 that is slidably attached to the horizontal bar 35 of the support arm. The reason why the inwardly expanding clamp tool 32 is made slidable along the horizontal rod 35 is to enable the center of the skirt whose waist is fixed to the clamp tool to be aligned with the center of the inner trowel 10.

FIG. 5 shows the front of the intermediate trowel main body 11, and FIG. 6 shows the cross section. The middle trowel main body 11 is composed of three layers of chambers, and has a steam chamber 13 in the center and outer chambers 14 and 15 for hot air and vacuum on both sides thereof. The central steam chamber 13 is made of two wire meshes or two iron plates 13 with many small holes.
The outer chambers 14 and 15 are the spaces between the iron plates 131 and 132 and the adjacent plate materials 140 and 150 having a large number of small holes adjacent to the outer sides thereof. Iron plate 13
Connecting portions 133 are provided at various places between 1 and 132 to prevent explosions. A steam inlet 16A and a steam outlet 16B leading to the steam chamber 13 are provided on one side of the base of the intermediate trowel body 11, and outer chambers 1 are provided on both sides of the base of the intermediate trowel body, respectively.
Vacuum connection ports 17A, 17 leading to 4, 15
B and a hot air connection port 18 are provided. It is preferable that guide portions 18A are provided in the outer chambers 14 and 15 on both sides of the hot air connection port 18 to facilitate the upward movement of air and improve response.

FIG. 7 shows a cross section of the lower irons 21, 22. Lower trowel 2
As can be seen from FIG. 6, numerals 1 and 22 have a steam chamber 27 and a vacuum chamber 28 located on the top side of the iron in contact with the steam chamber 27.
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 FIG. 4, two blowers 47 and 48 are provided in the machine frame 1, the air outlet 47A of the first blower 47 is connected to the air pipe 50, and the air outlet 48A of the second blower 48 is connected to the outdoors. It's open. 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 test pipe line is a diaphragm valve (double valve). It is open to the outdoors via 49. 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, the blast pipe 50 is connected to the outer chambers 14 and 15 of the inner iron 10 via solenoid valves (hot air valves) 52 and 53, respectively, and the intake pipe 60 is connected to a solenoid valve, respectively. (Bakyum valve) 61,
62 to the outer chambers 14, 15 of the intermediate trowel 10
However, a vacuum chamber 28 is also connected via electromagnetic valves (vacuum valves) 63 and 64. 7
0 is a steam pipe, to which are connected the steam chamber 13 of the middle trowel 10 and the steam chambers 27 of the lower trowels 21 and 22, and to which the middle trowel is connected via solenoid valves (steam valves) 71 and 72. The outer chambers 14, 15 of are connected. 55 is a drive switching valve for the pressurizing cylinder 3.

Next, the operation of the above device will be explained with reference to FIGS. 9 and 10.

Initially, it is assumed that the intermediate trowel 10 is in a vertical position (normal position) as shown in FIG. 9A.

Removing pleats from the skirt (Fig. 10A) First, tilt the clamping device 30 diagonally as shown by the dotted line in Fig. 1, hook one end of the waist of the skirt onto the knurl 43 of the clamping tool 32, and pull it to the right in Fig. 3. While pulling, insert the waist of the skirt between the knurls 43 and 44 of the clamp tool 32. When the hand is released, the knurls 43 and 44 expand due to the action of the spring 45, and the waist portion of the skirt is fixed to the clamp tool 32. Next, the support rod 34 of the clamp device 30 is pulled up, the skirt is inserted into the inner trowel 10 from above while the inner trowels 10 in the vertical position are overlapped, and the support rod 34 is pulled down. In this case, the skirt is rotated around the knurlings 43 and 44 as necessary to prevent the chuck of the skirt from coming within the plane of the inner trowel 10. Next, by pinching the sagging portions at both ends of the skirt with clips (not shown) and eliminating the sagging around the waist of the skirt, all the folds in the area facing the pressing surface of the inner trowel 10 are straightened directly below the eyelashes. Make sure it hangs down evenly. After that, start switch PB-
Press 3 (Figure 1).

Removing pleats on one side (Fig. 10B) When the start switch PB-3 is pressed, a middle trowel drive signal is generated, the electromagnetic solenoid SOL4-A of the drive switching valve 55 (Fig. 8) is turned ON, and pressure is applied. The inner trowel 10 moves to the right due to the action of the cylinder 3. When the inner trowel 10 rotates 11 degrees to the right, limit switch LS2 for detecting 11 degrees to the right turns on (first
(point b in figure 0). This turns SOL4-A OFF.
However, the middle trowel 10 stops at a diagonally inclined intermediate position as shown in FIG. 9B. At the same time, a steam timer T1 (not shown) is activated, and the steam valve 71 of the middle trowel 10 is opened for a certain period of time, for example, 10 seconds, and steam from the left chamber 14 of the middle trowel 10 is fed. As a result, steam is applied to the folds of the skirt, making it possible to easily straighten the wrinkled folds. Steam timer T1
When the operation of T2 is completed, the 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,
This is because the heated skirt is left alone and waits until the temperature drops to a temperature that the worker can touch. When the operation of the rest timer T2 ends, the vacuum valve 61 belonging to the left chamber 14 of the middle trowel 10 is opened.
The skirt is attracted to the left side of the middle trowel 10. Therefore, since the pleats of the skirt are not disturbed, the pleats of the skirt can be easily removed. In this pleat removal process, the supply of electricity to the vacuum valve 61 can be arbitrarily interrupted by a foot switch (not shown), thereby facilitating the pleat removal work.

Pressing one side and removing pleats from the other side (Fig. 10C) After removing pleats, turn on the start switch again.
Press PB3. This time, the electromagnetic solenoid SOL4-B (FIG. 8) of the drive switching valve 55 is turned on, and the inner trowel 10 moves to the left by the action of the pressurizing cylinder 3. When the middle trowel 10 rotates 15 degrees to the left, the middle trowel 10
comes into contact with the lower iron 21 and enters a pressurized state, and the limit switch LS3 for detecting the left end is turned on (point e in Fig. 10). This closes the vacuum valve 61 in the left chamber of the middle trowel 10. Also LS
3 is turned on, the steam timer T1 on the left side of the middle trowel and the steam timer T3 (not shown) on the right side of the middle trowel simultaneously operate. The steam valve 71 is opened by the timer T1, and steam is sent into the left chamber 14 of the middle trowel 10. Then,
Steam is applied to the skirt from the inside.

On the other hand, the steam valve 72 on the right side of the middle trowel 10 is opened for a certain period of time by the timer T3, and steam is sent into the right chamber 15 of the middle trowel 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 T1 is forcibly cut off. Therefore, when the middle trowel 10 is at the left end position, the timer T
1, the timer time cannot be extended manually, and the rest timer T2 is disconnected and becomes irrelevant.

Also, at the same time as the timer operation of timer T3 ends, timer T4 starts operating for a certain period of time, for example, 10 seconds.
For only seconds, the hot air valve 52 of the chamber of the middle iron 10 and the vacuum valve 63 of the lower iron 21 are opened (10th
point f in the figure). Therefore, hot air is blown into the skirt from the inside of the skirt, and at the same time it is vacuumed from the lower trowel 21, that is, from the outside of the skirt. When the operation of timer T4 ends (point g in Figure 10),
The hot air valve 52 and vacuum valve 63 are closed. In this way, sending hot air to the skirt from the left chamber 14 of the middle trowel 10 and simultaneously applying vacuum from the lower trowel 21 side is equivalent to pressing the skirt from the inside of the skirt. There is a big advantage that so-called hit does not occur on the rear skirt. On the other hand, timer T4
Simultaneously with the completion of the operation, the vacuum valve 62 of the right chamber 15 of the middle iron 10 opens. Since the timer T4 has already elapsed since the application of the steam, the temperature of the skirt portion resting on the upper side of the middle trowel 10 has dropped to the extent that it can be touched by hand. Therefore, as in the case of the intermediate position described above, it is possible to remove pleats for pressing 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).

Pressing the other side (Fig. 10D) After completing the pleat removal on the remaining side, press the start switch PB3 again (Fig. 10h)
point). Electromagnetic solenoid SOL4 of drive switching valve 55
-A (Fig. 8) is turned ON, and the middle trowel 10 moves to the right. SOL4-B turns OFF at the same time as the middle trowel 10 leaves the left end. The right 11° detection circuit is for middle trowel 1.
It is disabled due to the condition that 0 was on the left end before starting and PB3 was pressed.
Therefore, the intermediate trowel 10 passes through the intermediate stop position.
When the middle trowel 10 rotates 15 degrees to the right, the middle trowel 10 comes into contact with the lower trowel 22 and enters a pressurized state, and the limit switch LS4 for detecting the right end turns on (the first
(point i in figure 0). This closes the vacuum valve 61 in the left chamber of the middle trowel 10. Also LS4
When turned ON, the steam timer T5 on the right side of the middle iron
(not shown) is activated, the steam valve 72 is opened for a certain period of time, and steam is sent into the right chamber 15 of the middle trowel 10. As a result, steam is applied to the skirt from the inside. In order not to break the pressed state completed on the left side, use the middle trowel 1.
No steam or hot air is sent to the left chamber 14 of 0. Also, there is no need for downtime for removing folds. Therefore, steam timer T
5 is completed and the steam valve 72 is closed, a timer T6 (not shown) is activated, and the hot air valve 53 in the right chamber of the middle iron 10 and the vacuum valve in the lower iron 22 are activated for a certain period of time, for example, 10 seconds. 64 is opened (point j in Figure 10). Therefore, hot air is blown into the skirt from the inside of the skirt, and at the same time it is vacuumed from the lower trowel 22, that is, from the outside of the skirt, so that a good press without so-called hitting is achieved.

When the operation of timer T6 ends, pressing on both sides ends (point k in FIG. 10). Timer T6
When the operation is completed, the hot air valve 53 and the vacuum valve 64 are closed, SOL4A is turned off, and at the same time SOL4B is turned on, and the middle iron 10 is moved to the left. Then, when the stationary position is reached, LS1 turns ON.
This turns SLO4B OFF and stops at the normal position. Thus, one cycle is completed.

As described above, in the pressing method of the present invention, after inserting a skirt into a tiltable vertical dummy iron and fixing the waist part of the skirt to the upper part of the dummy iron,
Tilt the dummy trowel diagonally and hold it still, remove the pleats from the skirt while adhering the skirt to the upper surface of the dummy trowel, then move the dummy trowel to the opposite side so that the side from which the pleats were removed is on the bottom. Since it presses the pleat-removing surface of the skirt by tilting it down and pressing it against the lower trowel installed diagonally upward, even an unskilled person can remove the pleats and press with good straightness on at least one side of the skirt. can. Re-clamp the skirt so that the other side is on the pressing surface of the dummy trowel, and repeat the same operation to press both sides of the skirt.

The equipment for carrying out this method includes a vertical medium trowel that can be tilted by a dummy trowel drive device, a clamp device installed on the top of the dummy trowel for hanging the skirt, and one side of the dummy trowel that is opened diagonally upward. The dummy iron has a steam chamber and an outer chamber that is in contact with the chamber and is located on the lower iron side, and the lower iron has a vacuum chamber formed on the upper side. A control device for a dummy trowel drive device that moves the trowel to a normal position where it is upright, an inclined position close to the lower trowel, and a press position where it is pressed against the lower trowel, and a control device for vacuuming the outer chamber of the dummy trowel at the above slanted position and pressing. Since the system is equipped with an air intake control device that blows hot air into the outer chamber of the dummy trowel and at the same time vacuums the vacuum chamber of the lower trowel at the same time, the skirt is pressed from the back side, resulting in a so-called uneven finish. It can be pressed well.
