Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for supplying a pattern to be inserted into a shirt to a shirt folding machine or the like.

[0002]

2. Description of the Related Art A pattern supply device for automatically supplying a pattern to a cradle of a shirt folding machine, as shown in FIG.
Inside the pattern storage box 50, a plurality of patterns R are stacked vertically and stored, and the stored patterns R are sucked by an air suction member 51 equipped with a vacuum pad 52 in order from the upper side to store the pattern R. The pattern is pulled up to the outside and conveyed to a predetermined set position.

[0003]

However, in the structure in which the pattern papers stacked as described above are sucked by the negative pressure generated by the air pressure, the stacked pattern papers are closely attached to each other, and the vacuumed air causes the pattern papers on the upper side. By passing and applying a suction force to the lower template, it is often the case that several templates are simultaneously sucked, and it is difficult to reliably take out the template one by one from the upper template.

In order to cope with such a problem, as shown in FIG. 20, a pawl 53 (or a brush) is provided on the side wall of the storage box 50, and the machine is in the process of pulling up several patterns R that have been sucked at the same time. The method of scraping off is considered.

In the above method, since it is difficult to scrape off the pattern paper which is firmly adhered by one claw 53, it is usually necessary to attach a plurality of claws 53 (or brushes) to the storage box. Since such pawls 53 are projected to the paper pattern side, the scraped-out paper pattern R is often caught between the pawls 53 as shown in the figure during the fall and stops in an inclined state. Therefore, when the air suction member 51 descends into the storage box 50 next time, the pattern R is forcibly deformed.

On the other hand, if the pawl 53 is arranged as close as possible to the uppermost surface of the stored pattern paper, and the pawl 53 is scraped off and then the pawl 53 is allowed to escape laterally, the above-mentioned problems are solved. However, such a method has the drawback of making the structure of the device considerably complicated and increasing the cost.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a feeder which is capable of surely sucking pattern paper one by one with a simple structure.

[0008]

In order to solve the above problems, the present invention is directed to a paper pattern storage box for accommodating a plurality of shirt pattern papers stacked vertically and a pattern paper storage box above the paper pattern storage box for suction. The air suction means for pulling up is provided, and the air blowing means for blowing high-pressure air to the surface of the drawn pattern is provided on the pattern drawing path by the air suction means.

[0009]

In the above structure, air is blown onto the surface of the template to bend the template during the pulling by the air suction means. Due to this bending, the closely contacted pattern papers are displaced from each other to form a gap between the upper and lower pattern papers, the close contact state of the pattern papers is released, and the suction action on the lower pattern papers is released.

Bend the collar portion T of the pattern set on the lower surface of the sheet upward.

The shirt folding machine of this embodiment has the above-mentioned structure, and its operation will be described below.

Before starting the work, the elevating frame 5 is lowered slightly so that the upper surface of the movable receiving base 3 is set slightly below the lower surface of the fixed receiving base 2.

In this state, the air suction member 17 of the paper pattern supply device 14 sucks the paper pattern R on the upper side of the storage box 16 and sets it on the lower surface of the fixed pedestal 2. The vacuum pad 21 adsorbs the paper pattern R. Or the lift cylinder 2
While raising the template R sucked by 2, air is blown from the air suction member 20 to the surface of the template to bend the template R as shown in FIG.

By this bending, a downward force is applied to the pattern paper, and the closely adhered pattern papers are separated from each other. Further, due to the bending, the upper and lower patterns are displaced from each other, and a very small gap is formed between the respective patterns, so that the negative pressure between the patterns, which causes the suction action, is sharply reduced, and the lower pattern is formed. Has the effect of dropping.

Further, turbulence of air is generated on the surface of the pattern paper R on which air is blown by the air blowing tube 20, and the turbulent air enters the space between the pattern papers to rapidly move up and down. Has the effect of separating the paper pattern.

Due to the above-mentioned action, the air suction member 17 adsorbs only one pattern paper stored in the uppermost part of the storage box 16, and the separated lower pattern paper is stored. Since there is no protruding obstacle such as a claw or a brush on the side wall of the box 16, the box 16 falls into the storage box without tilting midway and is stored in the storage box in a normal posture.

When the template is sucked in this way, the template is inverted and rotated to face the lower surface of the fixed receiving base 2, and the template is gripped by the template gripper 37. Next, the bending tool 38
To bend the collar portion T of the template R upward, and thereafter, as shown in FIG. 13, the lifting cylinder 36 of the shirt conveying device 15 is operated to integrally form the template grasping tool 37 and the folding tool 38. The collar paper portion T is raised and projected onto the upper surface of the fixed pedestal 2.

Then, on the upper surface of the fixed pedestal 2, the button side of the shirt is directed upward, and the collar portion of the shirt is inserted into the protruding collar paper portion T so that both sleeves and both sides of the body portion are on both sides of the pedestal 2. Hanging from one side, set shirt S.

Next, both sleeves of the shirt are gripped by the grip plates 32, 32, and the shirt conveying device 15 is moved to move the shirt S and the pattern R on the fixed pedestal 2 to the tip of the movable pedestal 3. Let At the time of this movement, since the movable pedestal 3 is lower than the fixed pedestal 2, as shown in FIG.
Along with the movement, rides on the upper surface of the movable pedestal 3 and faces the back surface of the shirt.

As shown in FIG. 15, the shirt S has a movable pedestal 3
When it is moved to the folding position, the both sleeves of the shirt and the pattern are released, and the elevating frame 5 is raised so that the heights of the movable pedestal 3 and the fixed pedestal 2 coincide with each other. From that state, as shown in FIG. 16, the folding plates A to G and F to G on both sides of the pedestals 2 and 3 are slid in order from the upper side so that both sleeves and the body of the shirt are respectively pedestal. Fold to the bottom of a few.

Then, the elevating frame 5 is raised to
When the movable pedestal 3 is pulled up as shown in FIG. 7, the lower half of the shirt folded between the fixed pedestal 2 and the folding plates F and G is pulled out, and then the movable pedestal 3 is placed on the vertical folding table 13. When the shirt S is moved toward the front, the shirt S is folded back in the longitudinal direction as shown in FIG.

After that, the movable pedestal 3 and the folding plates A to G are moved in the opposite directions, and the shirts are pulled out in order from the inside of the shirt. Left on.

In the above example, the pattern inserted into the back surface of the shirt has been described, but the present invention can be applied to the pattern inserted into the collar portion of the shirt in the same manner as described above.

[0041]

As described above, according to the present invention, air is blown onto the surface of the aspirated pattern paper, and the air pressure bends the pattern paper. Therefore, it is possible to reliably separate the closely attached pattern paper with a simple structure. It can be automatically supplied one by one.

Further, since the storage box has no clogs or other obstacles, the separated pattern can be accurately dropped into the storage box without tilting, and a stable pattern can be supplied.
