Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a shirt press machine for press-finishing shirts such as dress shirts and work clothes.

[Conventional technology]

Conventional shirt press machines are equipped with air bags on both sides of the torso that can be expanded and deflated to accommodate changes in shirt size. Afterwards, the front and rear surfaces are crimped with a pair of hot plates for a press finish. In such pressing operations, if the hot plate is pressed with the front body of the shirt wide open due to the expansion of the air bladder, the shirt will be molded into a distorted shape, resulting in an extremely poor finish. For this reason, conventional body stands are equipped with a front presser that fixes the lower part of the front body of the shirt to prevent the front body of the shirt from opening too much.

[Problem that the invention seeks to solve]

This type of front presser usually has a T-shaped plate whose lower end is fixed to the lower part of the body stand. In this case, the upper end of the front presser uses its own elasticity to press against the torso to secure the front of the shirt. However, with this structure, when putting the shirt over the body stand, while removing the front presser from the body stand,
Since it is necessary to sandwich the lower part of the shirt between the body stand and the front presser, there is a problem in that the work is time-consuming.

For this reason, Japanese Utility Model Publication No. 61-7679 proposes a mechanism in which the front presser is moved mechanically.

As shown in FIGS. 9 and 10, the front presser 21 of the T-shaped spring is fixed to the upper part of a rotating block 23 that is attached to the lower front end of the body chamber 22 so as to be swingable in the front-rear direction. , the rotation block 23 is swung by the action of a horizontal air cylinder 24 and a cam mechanism 25, and the front presser can be pressed into the barrel chamber by driving the air cylinder 24, so it is not a manual type. It is superior in that it is easier to work with than .

However, in the above conventional structures, the front presser simply presses the front of the shirt, so when the hot plate is next pressed, the wrinkles on the surface of the front are not stretched out. It may be pressed. As described above, if the front body is not fixed in a state where the wrinkles are smoothed out, when the air bladder is inflated, the shirt will not be inflated to the correct shape, and wrinkles will remain on the surface of the finished shirt. For this reason, conventionally, when crimping a hot plate, the worker had to pull the bottom edge of the shirt downward to smooth out the wrinkles on the surface of the shirt. There is a problem with the risk of burns due to contact with the tools.

Also, when crimping the hot plate, the front presser does not move and remains pressed against the shirt, so it is pressed at the same time as the hot plate is crimped, and the crimping marks are left on the shirt, resulting in a uniform finish. There is also the problem of not being able to

The present invention was made with the aim of solving the above-mentioned problems with the conventional front presser.

[Means for Solving the Problems] 'In order to solve the above problems, the present invention provides a front presser at the lower front end of the trunk chamber that is movable in the vertical direction and can be moved toward and away from the trunk chamber. The structure is such that a drive mechanism is provided which is connected to the front holding tool and moves it, approaches and separates it.

[Effect]

In the shirt press machine configured as described above, after the shirt is placed over the body chamber, the front presser is crimped onto the body chamber to fix the front body of the shirt to the body chamber, and then the front presser is pressed onto the body chamber. Move the button downward to tighten the shirt downward and smooth out the wrinkles on the surface of the shirt. In this state, press finishing is performed by expanding the air bag and pressing the hot plate.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 4, the body chamber 1 includes a substrate 2,
It consists of a pair of air bags 3, 3' attached on both sides thereof, and is installed upright on the top of a rectangular pipe 4 whose interior becomes a passage for hot air to the air bags.

A front presser 5 made of a T-shaped leaf spring and a drive mechanism 6 for driving the front presser 5 are provided on the front surface of the rectangular pipe 4. Next, the drive mechanism 6 will be explained.

As shown in FIGS. 2 to 4, a sliding plate 9 is movably attached to a vertical rail 7 fixed to the front surface of the square pipe 4 via a bearing 8. At the upper end of 9, a swinging block 10 is attached to a horizontal shaft 11.
The lower end of the front presser 5 is fixed to the upper part of the swing block 10.

The sliding plate 9 has an air cylinder 12 extending in the left and right direction.
is attached, and a cam plate 13 is fixed to the tip of the piston rod of the air cylinder 12.

The cam plate 13 includes a cam groove 14 having a horizontal portion 14a at one end and an inclined portion 14b at the other end, and a cam surface 15 forming an upper part of the cam plate 13. It consists of an inclined surface 15b parallel to the inclined portion 14b of the groove 14, and a horizontal surface 15a continuous to the inclined surface 15b.

A fixed roller 16 attached to the rectangular pipe 4 is movably fitted inside the cam groove 14 by being held by guide plates 17 on both sides. A protruding roller 18 is in sliding contact. In the normal state before the press starts, the position of the cam plate 13 is as shown in FIGS. 2 and 4. In this case, the position of the cam plate 13 is in the state shown in FIGS. The distance X from the contact position to the horizontal surface 15a is set smaller by a predetermined amount than the distance y from the contact position of the fixed roller 16 on the cam 'a14 to the inclined portion 14b.

This embodiment has the above-mentioned configuration, and before the start of pressing, the front presser 5 is set at a position facing the front surface of the body chamber 1, as shown in FIG. In this state, the front presser 5 is located away from the body chamber 1, and the front body of the shirt A is held in the body chamber 1.
and the front presser 5.

When the air cylinder 12 extends and moves the cam plate 13 in this state, the roller 18 of the swing block 10 moves from the inclined surface 15b on the cam surface 15 to the horizontal surface 15a, as shown in FIGS. 5 and 7. The swing block 10 moves to the shaft 11.
It swings toward the trunk chamber 1 using the fulcrum as a fulcrum. Therefore, the upper part of the front presser 5 is pressed against the body chamber 1, and the front body of the shirt A is pressed against the body chamber 1. On the other hand, since the fixed roller 16 only moves in the horizontal portion 14a within the cam groove 14, the sliding plate 9 does not move.

When the air cylinder 12 further extends and moves the cam plate 13, as shown in FIGS. 6 and 8, the fixed roller 1
6 enters the inclined portion 14b of the cam groove 14, and as it moves, the sliding plate 9 is pushed downward and moves downward along the rail 7. In this case, the roller 18 of the swing block 10
is moving on the horizontal part of the cam surface 15, so the front presser 5
moves downward while keeping the front body pressed against the shirt.

For this reason, the front section of shirt A is stretched downward,
Surface wrinkles are smoothed out.

As shown in FIG. 8, the movement of the front presser 5 stops when the upper part of the front presser is located below the moving range of the hot plate 19, and then, as the air bag 3 expands, the body chamber 1 hot plate 1
9 is crimped to give the shirt a press finish.

When the pressing operation is completed and the hot plate and air bag return to their original states, the air cylinder 12 contracts, and the front presser 5 and sliding plate S move in the opposite direction to the above operation, as shown in FIG. Returns to the state before the start of pressing.

As described above, in the above-mentioned embodiment, since the front presser can be moved in the front-rear direction and the up-down direction by driving one air cylinder, there is an advantage that the entire apparatus can be made compact. In addition to the above structure, for example, FIGS. 9 and 10
Front presser 21, cylinder 24, and cam mechanism 25 in the figure
The entire front presser structure including the front presser structure may be provided to be movable up and down with respect to the trunk chamber 22, and the structure may be provided with a drive device for moving it up and down.

〔Effect of the invention〕

As described above, in this invention, the front presser is crimped to the front body of the shirt and pressed against the body chamber, and then moved downward to tension the front body, so that the shirt is sufficiently wrinkled. Press finishing can be performed in the stretched state, allowing accurate and stable press forming. Furthermore, since there is no need for the operator to pull the bottom edge of the shirt to smooth out wrinkles as in the past, highly efficient and safe pressing operations can be performed.

Furthermore, when crimping the hot plate, the front presser can be moved downward to remove it from the crimping area of the hot plate, which eliminates crimping marks from the front presser from the finished surface of the shirt, resulting in a uniform gloss. You can get a beautiful finish.
