Description

DETAILED DESCRIPTION OF THE INVENTION Purpose of the Invention (Industrial Field of Application) The present invention involves placing a fabric on a crease forming guide groove of a predetermined width before forming a crease on the fabric using a press device, and A fabric folding guide method using a fabric folding guide device that folds the fabric toward the guide groove side by a pair of shutters that slide and protrude from the left and right in a superimposable manner, and sends the folded fabric to the press device along the guide groove. It is related to.

(Prior Art) When folded fabric with a placket for Y-shirts, blouses, etc. is folded using a press device, the fabric folding guide device is generally used to set the fabric in a predetermined fold shape in advance. has been adopted. The fabric set into a predetermined fold shape by this fabric folding guide device is fed from the entrance of the press device into the inside of the press device along the crease setting guide groove, and the fabric is folded into a predetermined shape by the pulling and pressing actions of the press device. A crease is added. In the conventional fabric folding guide method using a fabric folding guide device, in order to ensure that the fabric placed on the crease setting guide groove is folded back by the shutter, the same guide groove is placed on the fabric placed on the crease setting guide groove. A method has been adopted in which a presser plate with a width slightly narrower than the width of the guide groove and approximately the same length as the guide groove is placed, and the presser plate and the fabric are fitted into the crease setting guide groove.

(Problems to be Solved by the Invention) However, the intervention of the work step of fitting the presser plate together with the fabric into the crease setting guide groove is one factor that delays the work time for setting the fabric in the crease setting guide groove. However, as long as a presser plate is used, it is difficult to improve productivity. Moreover, especially when forming the placket of a Y-shirt or the like in three, a high level of precision is required to align the edge of the fabric with one fold, but the fabric may shift when manually pressing down the center of the slope. It is difficult to maintain stable quality.

Structure of the Invention (Means for Solving Problems) Therefore, the present invention targets tri-fold formation, and the bottom corner of the crease setting guide groove on the lower shutter side of the pair of shutters on the left and right sides of the crease setting guide groove. The fabric on the guide groove is sucked into the suction port formed along the guide groove, and while maintaining this suction state, the lower shutter is slid out and one side of the fabric is folded back toward the crease setting guide groove. The upper shutter was slid to protrude while the upper shutter was protruding, and the other side of the fabric was folded back toward the crease setting guide groove side.

(Function) That is, if the fabric is attracted along the bottom corner of the crease setting guide groove on the lower shutter side, and the lower shutter is protruded in this state, one side of the fabric will be guided along the corner. It will definitely be folded back towards the groove side.

Next, by protruding the upper shack, the other side of the fabric is reliably folded back toward the guide groove along the leading edge of the lower shutter. At this time, if the tip edge of the protruding lower shank is set to almost match one side edge of the folded fabric, the crease on the other side of the fabric and the - side light edge will be aligned. Matches accurately. - (Example) Hereinafter, an example embodying the present invention will be described based on the drawings.

As shown in FIG. 1, a support plate 3 is placed and fixed on a support box 2 supported by casters 1, and a press device 4 and a fabric folding guide device 5 are placed and fixed on the support plate 3. has been done. The press device 5 has a function of drawing the fabric between a pair of upper and lower endless belts 6.7 and applying heat pressing while transferring the fabric between both belts 6.7, and the lower press belt 6 is placed on the entrance 4a side. The upper press belt 7 is stretched between the lower press roller 8 on the inlet side and the lower press roller on the outlet side (as shown), and the upper press belt 7 is stretched between the upper press roller 9 on the inlet side 4a and the upper press roller on the outlet side (as shown in the figure). road).

To explain the fabric folding guide device 5, a suction case 11 with an open top is fixed to the lower surface of the base 10, and a pipe lla is connected to the side surface of the case 11. Corresponding to the upper opening of the suction case 11, the base 10 has a suction hole 10 elongated in a direction perpendicular to its longitudinal direction.
a are arranged in the longitudinal direction. A pair of guide groove forming plates 12 and 13 are arranged parallel to each other on the base 10 so as to be parallel to the arrangement direction of the through holes 10a, and one guide groove forming plate 12 is spaced apart from the through holes 10a on the base 110. At the same time, the other guide groove forming plate 13 is tightened and fixed by a screw (not shown) so as to cover a part of the through hole 10a so as to be able to slide in a direction perpendicular to the longitudinal direction of the other guide groove forming plate 13. . Therefore, a guide aK is formed between the guide groove forming fixed plate 12 and the guide groove forming movable plate 13 so that the width can be adjusted, but within the range of this width adjustment, the through hole 10a is always located at the bottom of the guide groove. It's coming out.

A shutter 14 is placed on the guide groove forming movable plate 13, and a plurality of slide holes 14a formed long in a direction perpendicular to the longitudinal direction of the shutter 14 and similar long holes formed in the guide groove forming movable plate 13 are provided. A screw 15 (not shown) is screwed onto the base 10 through the screw 15 (not shown). Therefore, the shutter 14 is slidable in a direction perpendicular to its longitudinal direction, and is at a retracted position where its inner edge is located on the guide groove forming movable plate 13 as shown in FIG. 2, and at an inner position as shown in FIG. It is slidable between a crease setting position in which the edge protrudes upward into the guide groove. Note that a scale is engraved on the shutter 14, and a plurality of magnetic gauges 16 are attracted thereto.

A shutter 17 is placed on the guide groove forming fixing plate 12, and a screw 18 is screwed into the base 10 through the guide groove forming fixing plate 12 and a slide hole 17a formed long in a direction perpendicular to the elongated direction of the shutter 17. ing. Therefore, the shutter 17 is slidable in a direction perpendicular to its long plane direction, and is in a retracted position where its inner edge is located on the guide groove forming fixing plate 12 as shown in FIG. 2, and in an inner position as shown in FIG. It is slidable between a crease setting position in which the edge protrudes upward into the guide groove.

The thickness of the guide groove forming fixed plate 12 is the same as that of the guide groove forming movable plate 13.
The shutter 17 is set to be slightly larger than the sum of the thickness of the shutter 14 and the thickness of the shutter 14, so that the shutter 17 is slid and projected above the shutter 14.

A plurality of leaf springs 19 (only one is shown in the drawing) are fixed directly below the base 10 corresponding to the guide groove forming fixing plate 12, and their tips are bent upward from one side edge of the base 10. It is installed protrudingly. As shown in FIG. 2-3, when the upper shutter 17 is in the retracted position, the tip of the leaf spring 19 is in contact with the lower surface of the upper shutter 17, and as shown in FIG. 4, the upper shutter 17 is in the crease setting position. When in position, the tip of the slope spring 19 comes into contact with the side edge of the upper shutter 17.

A pair of U-shaped legs 20.2 are provided between both bent edges of the base lO.
1 is constructed, and one leg 20 is set longer than the other leg 21. Then, on the support plate 3, an elastic channel-shaped position regulating bar 22, 23 is installed to extend the length of both legs 2.
The legs 20.21 are arranged and fixed at almost the same distance as the distance between the legs 20.21 and the position regulating bars 22.2.
The fabric folding guide device 5 having the above structure is placed on the support plate 3 so as to sandwich the fabric folding guide device 3 .

A blower B is housed in the support box 2, and a pipe 24 connected to the first suction port B1 is connected to the support plate 23.
The pipe 24 and the pipe lla
are connected. Proa B is provided with a second suction port B2, and normally inhalation is performed from the suction port B2, but by turning on the foot switch F, the suction can be switched to the first suction port B I Ill. , Entrance Bl, B after rain
The air taken in from B2 is exhausted from the exhaust port B3.

A method of using the fabric folding guide device 5 constructed as described above will now be described using the placket formation of a Y-shirt as an example.

As shown in FIG. 2, with both shutters 14 and 17 in the retracted position, the fabric W is placed on the crease setting guide groove in alignment with the position of the magnet gauge 16, and the foot switch F is turned on.

As a result, a suction air flow is generated in the through hole 10a on the bottom corner of the guide groove, and the fabric W on the guide 2alK flows into the guide groove along the side corner of the lower shutter 14 at the bottom. It is adsorbed.

Next, as shown in FIG. 3, when the lower shutter 14 is slid to the crease setting position, one side of the fabric W is folded back into the guide groove along the row of suction holes 10a, and one side edge of the fabric W is folded back toward the guide groove. and the leading edge of the lower shutter 14 substantially coincide with each other. After folding one side of the fabric W, if the upper shutter 17 is slid to the crease setting position as shown in FIG. It is folded back to the side along the leading edge of 14 into the guide groove. In this state, the tip of the leaf spring 19 comes into contact with the outer edge of the upper shack 17, and the upper shack
17 is regulated and held at the crease setting position.

After the fabric W is folded and set, the foot switch is turned OFF and the fabric W is moved along the guide groove K to the press device 4.
When the cloth W is fed into the interior from the entrance 4a, the cloth W is drawn into the press device 4 from the cloth folding guide device 5 side by the pulling action of the press device 4, and is subjected to a pressing action.

The fabric W receives an adsorption action only on the lower shutter 14 side,
On the upper shutter 17 side, the guide groove does not attract the bottom surface. This is essentially important in forming a so-called perfect tri-fold, in which one side edge of the fabric W matches the fold on the other side. That is, when one side of the fabric W is folded back, when the upper shutter 17 is made to protrude and the other side of the fabric W is folded back, the upper shutter 17 is not adsorbed to the corner of the upper shutter 17 at the bottom of the guide groove. As the shutter 17 protrudes, the other side of the fabric W is pulled, and as shown in FIG. 4, the upper and lower portions of the fabric W above the guide groove, excluding the middle portion, are appropriately tensioned. Therefore, even when the crease-shaped bottom portion on the upper shutter 17 side is sharply folded back along the leading edge of the lower shutter 14 and subjected to the pressing action of the press device 4, one edge of the fabric W remains at the crease portion. There will be no inconveniences such as folding or wrinkles at the folds. If the guide groove attracts the fabric W to the bottom corner of the upper shutter 17, the lower shutter 1
4 cannot be sharply folded back along the tip edge, resulting in the above-mentioned disadvantage.

In addition, the fold position of the fabric W is specified by the row of suction holes 10a and the tip edge of the lower shutter 14, and the fabric W can be set without using a conventional presser plate. Work efficiency is greatly improved.

The present invention is, of course, not limited to the above-mentioned embodiments. For example, a suction slit may be provided in the crease setting guide groove along the lower shutter side corner of the bottom in place of the suction hole row to attract the fabric. It is also possible to automatically operate the sliding operation of the shutter using an air cylinder.

Effects of the Invention As detailed above, in the present invention, the crease setting guide groove is guided to the suction port formed along the bottom corner of the lower shutter side of the pair of shutters on the left and right sides of the crease setting guide groove. The fabric on the groove is sucked, and while maintaining this suction state, the lower shutter is slid out and one side of the fabric is folded back toward the crease setting guide groove side, and then the upper shutter is slid out while the lower shutter is kept sticking out. Since the other side of the fabric is folded back toward the crease setting guide groove side, it is possible to efficiently and precisely form the three-fold placket of a Y-shirt, blouse, etc., which is an excellent effect.
