Insert a collar. Further, the sleeve and the trunk of the shirt S are set in a state of being hung down from both sides of the fixed receiving table 1. The above-mentioned setting of the shirt may be performed after the pattern R is supplied onto the fixed receiving table 1. However, after the shirt is first placed on the fixed receiving table 1, the pattern R is transferred from the supply port 9 to the back of the shirt. May be supplied to the side and set.

When the setting of the shirt is completed, the shirt transport device 35 is operated to move the shirt to the movable receiving table 2. At this time, since the pattern R is mounted on the back of the shirt S with the insertion portion T inserted into the collar, the pattern R is simultaneously moved to the movable receiving table 2 by moving only the shirt S by the shirt transport device 35. Can be done.
When the shirt is moved in this manner, the upper half of the shirt S is located on the upper receiving stand 3 of the movable receiving stand 2, and the lower half of the shirt S is located on the fixed receiving stand 1.

In the movable cradle 2, both sleeves of the shirt S hanging from both sides of the upper cradle 3 hang down from both sides of the lower cradle 4. In the shirt folding operation, first, the uppermost folding plate A is moved so as to enter below the fixed receiving table 1 and the upper receiving table 3.

In this state, one sleeve of the shirt S is
It is in a state of being folded between the upper receiving table 3 and the folding plate A and between the folding plate A and the lower receiving table 4, and is folded twice in the opposite direction. That is, the state is the same as the state in which the sleeve is folded in the reverse direction, and the lower support 4 performs the same function as the folded plate (see FIG. 9A).

Next, the lower folding plate B is inserted under the folding plate A, and the lower folding portions C and D are successively inserted.
Is inserted between the upper and lower receiving stands 3 and 4 (see FIG. 9B), so that both sleeves of the shirt S are alternately folded back and forth between the upper receiving stand 3 and the lower receiving stand 4. Completely collapsed. In addition, the body of the shirt S that hangs down from both sides of the fixed support 1 has a shorter length than the sleeves, so the upper 2
It is folded only by the folding plates A and B.

When the folding of the shirt is completed as described above, each of the folding plates A, B, C and D is rotated in the opening direction,
Move away from the movable receiving table 2. Thus, the upper half of the shirt S is held between the upper support 3 and the lower support 4 of the movable support 2 by pulling out each folded plate. Next, the lifting unit 27 and the movable cradle 2 are raised, and the lower half of the shirt S is fixed to the fixed cradle 1.
From the movable cradle 2 and lift up while hanging from the movable receiving table 2.

Next, the slide 4 above the elevating unit 27
When the movable receiving table 2 is moved toward the vertical folding table 46 by moving the movable receiving table 3a forward, the lower half of the hanging shirt S comes into sliding contact with the upper surface of the vertical folding table 46, and as shown in FIG. The shirt is folded back in the longitudinal direction between the movable receiving table 2 and the movable receiving table 2.
Thereafter, the slide table 43a is retracted, and the movable support table 2 is separated from the vertical folding table 46, whereby the upper support table 3 and the lower support table 4 are pulled out from the sleeve of the shirt S, and the shirt is folded into a fixed shape. Is left on the vertical folding table 46.

As described above, in the structure of this embodiment, since the pattern R is supplied from the supply port 9 provided at the front end of the fixed receiving table 1, the setting of the shirt on the fixed receiving table 1 is performed before and after the supply of the pattern. Can be done either way. Further, in a state where the shirt and the pattern are set, other folding work can proceed freely regardless of the operation of the pattern transfer device 16. In addition, the pattern R is fixed to the shirt S and the
Can be moved to the movable receiving table 2 by sliding the upper surface of the pattern, the mechanism for holding the pattern R when the shirt is conveyed can be omitted, and the structure can be simplified.

In the above-described embodiment, the movable receiving table 2 is formed by the upper and lower receiving tables 3 and 4, but may be formed by one or three or more receiving tables. In addition, each folded plate A, B, C, D
Is designed so that the rocking arms 30, 31, 32, and 33 enter between the upper and lower supports 3 and 4 with a large radius of rotation. However, as in the case of the conventionally proposed shirt folding machine, each folding plate is horizontally oriented. A similar effect can be obtained by a structure that slides into the movable receiving table 2.

[0037]

As described above, according to the present invention, the pattern paper provided between the guide plate at the end of the fixed receiving base and the arc portion at the end of the fixed receiving base.
Since a supply port is provided at the upper end of the guide passage, and the pattern is directly attached to the back side of the shirt set on the fixed receiving table,
The setting work and the folding work of the shirt can be advanced simultaneously with the supply of the pattern paper, so that the efficiency of the work can be improved. In addition, since the pattern can be moved simultaneously with the shirt on the fixed receiving stand, a mechanism for holding the pattern while the shirt is moving can be eliminated, and the effect of simplifying the structure and saving space can be achieved. is there.
