DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical folding device for folding an upper half on a lower half of a shirt.

[0002]

2. Description of the Related Art Apparatus for folding a shirt such as a shirt in the longitudinal direction has been disclosed in Japanese Patent Laid-Open No. 4-338.
There is one proposed in Japanese Patent Publication No. 500.

[0003] In the device according to this publication, a movable receiving table for holding an upper half of a shirt folded in a horizontal direction is provided so as to be able to approach and separate in a horizontal direction with respect to a vertical folding table. By approaching the table, the lower half of the hanging shirt is stretched to the surface of the vertical folding table, and the center of the shirt is bent at an acute angle.

[0004] A holding plate for holding the lower half of the shirt on the vertical folding table and a folding plate for moving along the surface of the vertical folding table are provided between the movable receiving table and the vertical folding table. By moving toward the bent portion, the lower half of the shirt is folded back in the horizontal direction.

[0005]

In the above structure,
When shaping the bent part of the shirt with a sharp shape,
After the folded plate is brought into contact with the bent portion, the folded plate is further advanced to bend the bent portion.

When the folded portion is pressed by the folded plate, the upper half of the shirt moves forward on the movable receiving table because the lower half of the shirt is fixed by the pressing plate. In that case, if the pattern is attached to the back of the shirt, the pattern functions as a tension material, and the shirt can be folded into a fixed shape with almost the same dimensions as the pattern, but if the pattern is not attached, the shirt Since there is no function of maintaining the shape of the shirt, the shirt is simply pushed forward by the folded plate.

For this reason, if there is a difference in the elasticity of the shirt due to the difference in the amount of glue adhering to the fabric or the thickness of the fabric,
There is also a difference in the amount of forward movement of each shirt, and there is a problem that the operator needs to make corrections after the folding operation.

[0008] The above-mentioned problem similarly occurs even when the folded portion of the shirt is not pressed by the folded plate. In other words, if the elasticity of the shirting fabric varies depending on the amount of glue attached, the elasticity causes a difference in the rounded shape of the shirt generated in the bent portion, and the worker needs to make adjustments in order to fold the shirt to a certain size. Will be needed.

Therefore, the present invention solves the above-mentioned problems, and can fold the shirt into a predetermined shape by sharply shaping the bent portion regardless of the presence or absence of the pattern and the difference in elasticity of the shirt fabric. It is intended to provide a vertical folding device.

[0010]

In order to solve the above-mentioned problems, the present invention provides a movable receiving table for holding an upper half of a shirt so as to be able to approach and separate in a horizontal direction with respect to a vertical folding table.
The distance between the movable cradle and the vertical fold table is set so that the lower half of the shirt hanging from the movable cradle can be bent at an acute angle by the surface of the vertical fold table. A press plate that presses the lower half of the shirt against the surface of the vertical folding table, and a folded plate that moves toward the bent portion of the shirt along the surface of the vertical folding table are provided between the movable receiving table. A collar holding member is provided for pressing the collar of the shirt from the edge of the collar in the vertical direction of the shirt with a predetermined play.

[0011]

In the above structure, the lower half of the shirt is pressed by the pressing plate on the vertical folding table, and the shirt is pressed by the folding plate while the collar of the shirt is pressed by the collar pressing member on the movable receiving stand. When the bent portion is pressed, the upper half of the shirt is moved forward by the play between the collar holding member and the edge of the collar while receiving the resistance of the collar holding member.

When the collar holding member comes into contact with the edge of the collar, the upper half of the shirt stops moving, but during this movement, the folded plate is strongly pushed into the bent portion, and tension is applied to the shirt, thereby bending the shirt. Shape the part sharply.

[0013] In the above structure, play is provided between the pressing position of the collar pressing member and the edge of the collar, so that even if the size of the shirt changes and the position of the collar changes, the collar can be reliably formed. Can be held down.
