There is one proposed by the present applicant in Japanese Patent Publication No. Hei 4-75699. This folding machine arranges a fixed receiving table and a movable receiving table formed with the folding width of the shirt side by side in the horizontal direction,
On both sides of the cradle, a plurality of fold plates are formed alternately in the vertical direction with a gap, and a shirt is set with both sleeves hanging down on each cradle, and each fold plate is set. Are alternately slid downwardly of both cradles so that the shirt is folded between each cradle and the folding plate.

[0003]

In the above structure,
In order to completely fold both sleeves of a large-sized shirt with respect to the folding width of a given shirt (the width of the cradle), usually five or more folding plates are provided, and each of the folding plates is arranged in a certain order. However, the provision of such a large number of folded plates complicates the structure of the folded plates and their driving devices, and increases the cost.

[0004] In addition, the fact that the number of times the shirt is folded by the folded plate increases the cycle time of the operation, and has a drawback that it becomes a major obstacle in improving the productivity.

Accordingly, an object of the present invention is to provide a structure in which the shirt folding machine proposed above is modified to efficiently fold the shirt with a small number of folding plates.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is provided with a fixed pedestal and a movable pedestal having a width dimension formed by a folding width of a shirt, which are provided side by side.
The upper and lower pedestals facing each other with a vertical gap
The movable pedestal is connected vertically with the upper and lower pedestals.
The movable platform can be moved up and down in the width direction.
A plurality of folding plates entering alternately toward the gap between the upper and lower cradles from provided, the respective folding plates was the structure as to enter the gap between the upper and lower cradles with the rotational locus of the large curvature It is.

[0007]

In cradle disposed facing vertically [action], on the upper side of the upper cradle hanging both sleeves sets shirt above in that state
When the fold plate is slid in the gap between the lower cradle, the sleeve portions are alternately folded between the upper and lower cradle and the fold plate and folded. In the above structure, since the lower under stand itself performs the folding operation of the shirt, the number of folding plates can be reduced, and the number of folding cycles by the folding plates can also be reduced. Since the folding plate is driven by a turning trajectory having a large curvature, the cycle time is shortened, and the shirt is folded efficiently.

The elevating unit 8 includes guide bearings 20, 20 provided with a vertical guide shaft 19 attached to the rear end provided at the upper portion of the rear end of the apparatus frame 5 and near an intermediate height position.
(See FIG. 1). The movable receiving table 2 is integrally moved up and down by expansion and contraction of the elevating cylinder 21. At the upper end of the elevating unit 8, two guide shafts 22, 22 extending in the front-rear direction along the arrangement direction of the fixed support 1 and the movable support 2 are attached.
2, the cylinder 23 is attached to the upper plate 8a of the elevating unit 8 by the attachment stand 23a (see FIG. 1).

An end of the cylinder 23 is fixed to an L-shaped member 23b, and a lower end thereof is fixed to an upper end of a connecting plate 7 connected to the lower receiving base 4. Reference numeral 24 denotes a shirt presser bar for holding the shirt up. On the other hand, above the fixed receiving table 1, a vertical folding table 26 is provided parallel to the installation surface of the folding machine.

The vertical folding table 26 forms a surface inclined with respect to the surface of the movable receiving table 2 on which the guide shaft 22 is moved. When moved to the upper side of the folding table 26, as shown in FIG. 7, the lower half of the shirt S hanging from the movable receiving table 2 comes into contact with the vertical folding table 26 and bends, so that the shirt is folded in the length direction. .

At the lower part of the vertical folding table 26, a pressing rod 27 for pressing the surface of the shirt S set on the fixed receiving table 1 is provided.
And a cylinder 27X for moving the presser bar 27 down. Further, the cylinder 28 rotates the skirt push 29 and the roller 30.

The shirt folding machine of this embodiment has the above-described structure. Next, a shirt folding operation using the same will be described. As shown in FIGS. 1 and 2, the shirt S is set on the upper surface of the fixed receiving stand 1 with the button surface facing upward, and both side edges of the sleeve and the torso hanging down from both sides of the receiving stand 1. Then, the shirt transport device 15 is operated to move the shirt S to the tip of the movable receiving table 2.

As a result, the upper half of the shirt S is
, And the lower half of the shirt S is positioned on the fixed support 1. Further, both sleeves of the shirt S hanging down from both sides of the upper cradle 3 in the movable cradle 2 hang down through both sides of the lower cradle 4. Next, a shirt folding operation is performed. In this operation, first, as shown in FIG. 4, the uppermost folded 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 folded between the upper support 3 and the folding plate A and between the folding plate A and the lower support 4 and is turned twice in the opposite direction. It will be turned back. That is, in the conventional folding machine, the two folded plates are alternately operated, and the state is the same as the state in which the sleeve is folded in the opposite direction, and the lower support 4 performs the same function as the folded plate.

Next, the lower folding plate B is inserted below the folding plate A, and the lower folding portions C and D are successively inserted.
Is inserted between the upper and lower cradles 3 and 4 so that both sleeves of the shirt S are alternately folded back and forth as shown in FIG.
It is completely folded between the upper cradle 3 and the lower cradle 4. Further, the body of the shirt S, which hangs down from both sides of the fixed support 1, has a shorter hanging length than the sleeve, and is folded only by the two upper folding plates A, B.

The number of times of folding by such a folded plate is as follows.
Since the sleeve is folded back twice by the folding plate A and the lower support 4 at the time of the first folding, the number of times is smaller than that of the conventional structure by one time. For this reason, the movement of the folded plate is omitted by one time, and the folding cycle time can be shortened, and the number of folded plates and the number of driving parts such as a swing arm and an air cylinder for driving the folded plate can be reduced by one set. Therefore, the structure can be simplified.

In the above operation, the folded plates A, B,
When folded by C and D, the sleeve of the shirt always hangs down from the side of the folded plate, and the folded plate always folds the shirt in the same state, resulting in displacement or twisting of the sleeve. It can be securely folded up to the tip of the sleeve.

When the folding of the shirt is completed as described above, the folding plates A, B, C, and D are rotated in the opening direction and separated 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 raising / lowering unit 8 and the movable receiving table 2 are raised by the operation of the lifting cylinder 21, and the lower half of the shirt S is pulled out from the fixed receiving table 1 and is pulled up while hanging from the movable receiving table 2.

Next, the slide 23 above the elevating unit 8
When the movable receiving table 2 is moved toward the vertical folding table 26, the lower half of the hanging shirt S becomes the vertical folding table 26.
, And the shirt is folded back in the longitudinal direction between the vertical folding table 26 and the movable receiving table 2 as shown in FIG. Thereafter, the slide table 26 is moved backward, and the movable receiving table 2 is separated from the vertical folding table 26, so that the upper receiving table 3 and the lower receiving table 4 can be moved from the sleeve of the shirt S.
Is pulled out, and the shirt folded into a fixed shape is left on the vertical folding table 26.

As described above, in the structure of this embodiment, the upper half of the shirt S folded between the upper support 3 and the lower support 4 of the movable support 2 can be held. Of each folded plate A, B, C, D almost at the same time
Can be pulled out from the shirt, and the raising of the movable receiving table 2 and the returning operation of each folded plate can be performed simultaneously.

That is, in the conventional structure, the shirt can be pulled up and each folded plate can be returned in the structure of the embodiment at the time of the folding operation by the fifth folded plate, so that the working time can be shortened. .

Further, when the movable receiving table is lifted and moved to the vertical folding table, in the conventional structure, when the folded plate is returned, the sleeve of the shirt hangs down, so it is necessary to hold the sleeve by the folded plate. However, in the structure of the embodiment, the sleeve of the shirt can be held between the upper support 3 and the lower support 4 of the movable support, so that the folded plate can be returned at any timing.

Since the opening and closing operation of the folding plates can be freely performed in this manner, in the structure of the embodiment, the upper folding plates A and B are formed to have a length shared by the fixed receiving table 1 and the movable receiving table 2. It is possible to reduce the number of folded plates required for the fixed receiving table and the movable receiving table from seven sets to four sets in the conventional structure.

Although the movable cradle 2 is formed of two cradles 3 and 4 in the above embodiment, three or more cradles may be connected vertically. For example, in FIG.
Is a fixed pedestal that is connected to the upper pedestal 3 and the lower pedestal 4 so that the folding plates A and C can be operated to perform four folds, further reducing the cycle time. it can.
