Description

Detailed Description of the Invention (Industrial Field of Application) The present application relates to a fabric folding device, which folds fabric placed on a crease-forming guide groove composed of a guide groove-forming fixed plate and a guide groove-forming movable plate. The present invention relates to a fabric folding device in which a pair of shutters projecting from the left and right sides of a guide groove in a superimposed manner folds back the fabric into the guide groove, and feeds the folded fabric along the guide groove to a press device.

(Prior Art) When folded fabric with a placket such as a Y-shirt or blouse 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 in a prior stage. 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 is folded into the fabric by the drawing 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 into the crease setting guide groove. However, as long as a presser plate is used, it is difficult to improve productivity. Moreover,
Particularly 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 of the folds, but the fabric tends to shift when manually setting the presser plate. It is difficult to maintain stable quality.

Structure of the Invention (Means for Solving Problems) Therefore, the present invention targets trifold formation, and a guide groove forming fixed plate 12 and a guide groove forming movable plate 13 are mounted on the base 10 with a predetermined interval, The guide groove forming movable plate 13 is configured to be slidable in a direction orthogonal to the longitudinal direction of the base 10, and the wall thickness of the guide groove forming fixed plate 12 is set to be thicker by a predetermined dimension than the wall thickness of the guide groove forming movable plate 13. The fabric folding guide device further comprises a through hole 10a that opens above the base 10, connects to the suction case 11 provided at the lower part of the base 10, and is always partially covered by the guide groove forming movable plate 13. 5, shutters 14 and 15 mounted on the guide groove forming fixed plate 12 and the guide groove forming movable plate 13 and configured to slide with a predetermined stroke in a direction perpendicular to the longitudinal direction thereof, and a pair of upper and lower endless belts 6. , 7, the folded fabric is pulled in between the two belts 6, 7, and the press device heat-presses the fabric while transferring it between the belts 6, 7, thereby solving the problems of the conventional apparatus.

(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 shutter, 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 lower shutter in the protruding state is set to approximately match one side edge of the folded fabric, the fold on the other side of the fabric and the one side tip edge will match with high precision.

(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 4 includes a pair of upper and lower endless press belts 6 and 7.
It has a function of drawing the fabric between the belts 6 and 7 and applying heat pressing while transferring it between the two belts 6 and 7. The lower press belt 6 connects the lower press roller 8 on the entrance side 4a and the lower press roller on the exit side (not shown), and the upper press belt 7 is connected to the entrance 4.
It is stretched between the upper press roller 9 on the a side and the upper press roller (not shown) on the exit side.

To explain the fabric folding guide device 5, a suction case 11 with an open top is provided on the bottom surface of the base 10.
is fixed to the case 11, and a pipe 11a is connected to the side surface of the case 11. Corresponding to the upper opening of the suction case 11, the base 10 has elongated suction holes 10a arranged in the longitudinal direction in a direction orthogonal to the longitudinal direction thereof. A pair of guide groove forming fixed plates 12 and a guide groove forming movable plate 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. The guide groove forming movable plate 13 is fixed at a position apart from the through hole 10a, and is tightened with a screw (not shown) so as to cover a part of the through hole 10a so that the sliding position can be adjusted in a direction perpendicular to the longitudinal direction of the guide groove forming movable plate 13. Fixed. Therefore, the guide groove K 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. is always expressed.

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 arranged. A screw 15 (not shown) is screwed onto the base 10 through the screw 15 (not shown). Therefore, the shutter 14 can slide in a direction perpendicular to its longitudinal direction, and can be moved between a retracted position where its inner edge is located on the guide groove forming movable plate 13 as shown in FIG. 2, and a retracted position as shown in FIG. The inner edge is slidably switched between a crease setting position where the inner edge protrudes above the guide groove K. Incidentally, a scale L is engraved on the shutter 14, and a plurality of magnetic gates 16 are attracted.

A shutter 17 is placed on the guide groove forming fixing plate 12, and a screw 18 is screwed into the base 10 through a slide hole 17a formed long in a direction perpendicular to the longitudinal direction of the shutter 17 and the guide groove forming fixing plate 12. ing. Therefore, the shutter 17 is slidable in a direction perpendicular to its longitudinal direction, and as shown in FIG.
It is slidably switched between the upper retracted position and the crease setting position where the inner edge protrudes above the guide groove K as shown in FIG.

The thickness of the guide groove forming fixed plate 12 is set to be slightly larger than the sum of the thickness of the guide groove forming movable plate 13 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 FIGS. 2 and 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 the leaf spring 19 is in the position, the tip of the leaf spring 19 comes into contact with the side edge of the upper shutter 17.

A pair of U-shaped legs 20 and 21 are installed between both bent edges of the base 10, and one leg 20 is set longer than the other leg 21. and,
Elastic channel-shaped position regulating bars 22 and 23 are arranged and fixed on the support plate 3 at a distance that is approximately the same as the distance between the legs 20 and 21.
The fabric folding guide device 5 configured as described above is placed on the support plate 3 so that the legs 20 and 21 sandwich the position regulating bars 22 and 23.

A blower B is housed in the support box 2, and a pipe 2 connected to the first suction port B1 of the blower B is housed in the support box 2.
4 is projected from the support plate 23 to the outside, and the same pipe 2
4 and the pipe 11a are connected. Blower B
is provided with a second suction port B2, and normally suction is performed from the suction port B2, but by turning on the foot switch F, suction is switched to the first suction port B1 side, and both suction ports Air taken in from B1 and B2 is exhausted from exhaust port B3.

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

As shown in FIG. 2, when both shutters 14 and 17 are in the retracted position, the magnetic gauge 1
Place the fabric W on the crease setting guide groove K according to position 6, and turn on the foot switch F.
As a result, a suction air flow is generated in the through hole 10a on the bottom corner of the guide groove K, and the fabric W on the guide groove K is moved onto the bottom surface of the guide groove K along the side corner of the lower shutter 14 at the bottom of the guide groove K. It is adsorbed.

Next, as shown in Fig. 3, the lower shutter 14
If you slide it to the crease setting position, the fabric W
One side is folded back toward the guide groove K side along the suction holes 10a row, and one side edge of the fabric W and the lower shutter 1
4 almost coincides with the tip edge. After folding back one side of the fabric W, if the upper shutter 17 is slid to the crease setting position as shown in FIG. 14 is folded back toward the guide groove K side. In this state, the leaf spring 19
The distal end portion of the upper shutter 17 contacts the outer edge of the upper shutter 17, thereby regulating and holding the upper shutter 17 at the crease setting position.

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

The fabric W is subjected to an adsorption action only on the lower shutter 14 side, and is not adsorbed to the bottom surface of the guide groove K on the upper shutter 17 side. 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, after folding back one side of the fabric W, when the upper shutter 17 is projected and the other side of the fabric W is folded back, the guide groove K
By not adhering the fabric W to the corner of the upper shutter 17 at the bottom, the upper shutter 17
, the other side of the fabric W is pulled, and the fourth
As shown in the figure, the upper and lower portions of the fabric W portion above the guide groove K, excluding the middle portion, are appropriately tensioned. Therefore, even if the crease forming area on the upper shutter 17 side is sharply folded back along the tip edge of the lower shutter 14 and subjected to the pressing action of the press device 4, one side edge of the fabric W will not form the crease area. There will be no inconveniences such as folding or wrinkles at the folds. If the fabric W were to be adsorbed to the corner of the bottom of the guide groove K on the side of the upper shutter 17, it would not be possible to fold it back sharply along the tip edge of the lower shutter 14, resulting in the above-mentioned problem.

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, so that the fabric W can be set without using a holding plate like the conventional one. Work efficiency is greatly improved.

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

Effects of the Invention As detailed above, in the present invention, the fold 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 to 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, an excellent effect is achieved in that the trifold formation of the placket of Y-shirts, blouses, etc. can be performed efficiently and accurately.
