DETAILED DESCRIPTION OF THE INVENTION
The apparatus for folding a garment according to the present invention is for performing necessary folding on a garment conveyed in a state of being hung on a hanger. This is performed as a part of a series of processing systems including drying, wrinkling process, folding process, and packaging process for washed clothes as shown in FIG. 1, and the apparatus according to the present invention is also included in such a system. Improve overall work efficiency when used.
[0007]
According to the example shown in FIG. 1, the clothes are brought to the processing system in a state of being washed and dehydrated. And in a hanger hanging process, it spreads by a worker's manual work, is hung on a hanger, and is conveyed along a hanger movement path. It is assumed that the hanger movement path is continuous and there is no discontinuous part on the way. The drying, scraping process, folding process, and packaging process as described above are arranged in that order along the hanger movement path. Therefore, one hanger goes around the movement path. repeat.
[0008]
The hangers that have been transported with clothes are received by the folding machine at the hanger delivery section. The clothes hung on the hanger are handled while hung on the hanger after the hanger is delivered, and separated from the hanger before the clothes are folded. Therefore, in the input section for inputting clothes to the folding machine, the clothes may still remain on the hanger.
[0009]
In order to fold the sleeve of the garment thrown into the throwing portion, the sleeve fold portion is arranged along the conveyor that carries the garment thrown into the throwing portion or the throwing portion. The throw-in part is also a place where clothes are thrown into the folding machine, and the thrown-in clothes pass through a sleeve folding process and are conveyed by a conveyor, and further move at the same speed in the same direction together with the hangers on which the clothes are hung. . The throwing-in part is low on the front end side, is inclined high on the rear end side, and has a planar shape that tapers toward the front end so that both sleeves of the garment protrude left and right.
[0010]
At the sleeve fold, the clothes that are put on the hanger are folded. In order to fold a sleeve, it is desirable that the garment has its body part weakly fixed to the input part side and that the sleeve is completely separated from the body part. The body is fixed by means such as air suction or clamping. In the sleeve fold, the sleeves are arranged in an ideal position by injecting air from the lower nozzle first and then from the upper nozzle to the sleeve separated from the trunk. After that, the work of folding the sleeve with the tilt plate for folding the sleeve is performed. In order to separate the sleeves, it is effective to tilt the hanger forward or backward with respect to the lower part of the garment body so that the sleeve hangs from the shoulder.
[0011]

The hanger is received at the hanger delivery section and conveyed to the next process. It is a desirable work flow to fold the sleeves on the clothing during the conveyance and to remove the hangers after completion.
[0012]
The garment after the sleeve fold is further subjected to vertical fold and horizontal fold. These folds can be executed by a known method. Also, the hanger extracted from the garment goes around the hanger movement path and moves toward the first hanger application process. In this way, one hanger moves repeatedly through the hanger movement path, and does not leave the hanger movement path from beginning to end even if it stops halfway.
[0013]

The return portion 70 is located near the end of the delivery rail 68, and is a working portion that pushes and widens one open / close portion 18h by the restoring member 71 located between the open / close portions 18h of the closed hanger 18 to return the hanger 18 to its original shape. is there. The restoring member 71 is reciprocated by the cylinder device of the restoring drive unit 72. The hanger 18 restored to the open state is carried by the entrainment claw 66 until the end 73 of the delivery rail 68 is exceeded, and after passing the end 73, the hanger 18 is transferred to the downhill rail 74 and then transferred to the transfer rail 74. It overlaps the rail 17.
[0025]
Next, the folding work on the clothing 11 in the folding machine 15 and the movement of the hanger 18 will be described. When one hanger 18 on which the clothing 11 is hung is cut out from the stock portion 14, the hanger 18 hits the defining portion 31 to stop shaking and regulate the orientation, and the tip 41 of the throwing portion 40 protrudes so that the trunk portion The sleeves 11L and 11R are stopped in a state where the sleeves 11L and 11R are respectively guided to the taper upper portion of the insertion portion 40 (FIGS. 6 and 7). Thereafter, the delivery member 25 is raised, the hook portion 18f of the hanger 18 is engaged with the engagement portion 28, and the movement portion 27 moves so that the trunk portion of the garment 11 reaches the insertion portion plate surface 51. Begins to fall by the inclination drive part 42 (FIGS. 8A and 9A), and the left and right sleeves 11L and 11R are along the hypotenuse of the insertion part 40.
[0026]
The garment 11 is adsorbed relatively weakly by the insertion portion 40 in the state where the trunk portion is sucked by the suction nozzle 43, and the hanger 18 is placed at a position preceding the tip 41 of the insertion portion 40, so the sleeves 11L, 11R Hangs forward from the left and right of the garment 11 and leaves the body. In order to align the sleeves 11L and 11R in such a state on both sides of the trunk, air is injected from the lower nozzle 53 upward toward the shoulder opening (FIGS. 8B and 9B). After that, when the garment 11 moves on the sleeve folding plate, air directed toward the sleeve folding plate 52 from above is sprayed on the upper portion thereof, and the sleeves 11L, 11R blown outward in front and rear. (FIG. 8B), this time, it is completely hung outside the sleeve tilt plates 55 and 56 (FIGS. 11 and 13). At this time, the insertion unit 40 is assumed to be in the lowest position. From this state, the tilting plates 55 and 56 are rotated about three-quarters, and the sleeves 11L and 11R hanging down are turned to the upper surface of the trunk portion, and the sleeve folding operation is performed. During this operation, the clothing body is adsorbed by the suction port 44 on the sleeve folding plate surface 52, so that the clothing 11 is not moved and only the sleeve can be neatly folded (FIG. 14).
[0027]
After the sleeve folding is completed, the damper 48 leading to the suction port 44 is closed, the input unit 40 is raised (FIG. 16), and the moving element 27 is conveyed to the hanger extraction part 22 at the end of the conveying and moving rail part 29. During the conveyance, the moving speed of the moving element and the conveying speed of the clothes conveying unit 33 are the same. When reaching the hanger extraction part 22, the moving element 27 moves the hook 18f to the outside of the end of the transport rail, so that the hanger 18 comes to a position where it is latched by the latching part 62 at the tip of the extraction drive part (FIG. 17). The release piece 64g acts on the hanger 18, and the extraction drive unit 61 is operated as the opening / closing portion 18h is retracted. For this reason, the hanger 18 is smoothly pulled out of the collar without pulling up the garment 11 ( FIG. 19).
[0028]
When the latching part 62 for extracting the hanger 18 reaches the vicinity of the retreat limit of the extraction driving part 61, the release part 64 is retracted so that the hanger 18 becomes vertical and moves to the concave part 69 of the latching part 62 (see FIG. 22, FIG. 23), waits for the entrainment pawl 66, and when it rotates, the delivery rail 68 is raised while being entrained and stops when it reaches the restoring portion 70. In the restoring part 70, the opening / closing part 18h is pushed and expanded by receiving the acting force of the restoring member 71, and the hanger 18 is restored to the normal state where the clothes 11 are hung.
[0029]
FIG. 24 shows an example of all the steps related to folding the garment 11. As described above, the sleeve folding is performed first. Thereafter, when the removal of the hanger 18 is completed, the garment 11 is sent to the horizontal folding process 75, and the length is reduced to approximately one half. However, since the length of FIG. 24 is short, it is not folded in half and sent directly to the vertical tri-folding process 76, and the width is folded to one third (FIGS. 24 (d) and (c)). In the final folding step 77, the sheet is folded in two, and the finished product is discharged outside the machine (FIG. 24 (e)). The process following the packaging for the finished product may be the same as the conventional process. In the figure, reference numeral 78 is a horizontally folded knife, 79 is a forward / reverse conveyor for folding the same, 81 is a vertical trifold knife, 82 is a drive unit for the knife, 83 is a final folding knife, 84 is a sliding plate, 85, 86 denotes a conveyor, and 87 denotes a discharge conveyor.
[0030]
