Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a shirt press machine for pressing and 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 the size of the shirt. 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 section of the shirt wide open due to the expansion of the air bladder, the shirt will be molded in a collapsed state, resulting in an extremely poor finish. For this reason, traditional torsos are designed to prevent the front of the shirt from opening too much.
A front presser is attached to secure the lower part of the front body.

[Problem that the invention seeks to solve]

This type of front presser usually has a T-shaped plate spring whose lower end is fixed to the lower part of the body stand. With this, the upper end of the front presser uses its own elasticity to press against the torso to secure the front body of the shirt. However, with this structure, when putting the shirt over the torso stand, it is necessary to remove the front presser from the torso stand by hand and then sandwich the lower part of the front body of the shirt between the torso stand and the front presser. There is a problem that requires a lot of effort.

For this reason, Japanese Utility Model Publication No. 7679/1983 proposes a mechanism in which the front presser is moved mechanically.

As shown in FIGS. 6 and 7, a T-shaped spring front presser 21 is fixed to the upper part of a rotating block 23 that is attached to the front lower end of the torso stand 22 so as to be slidable in the front-rear direction. The rotating block 23 is swung by the action of a horizontal air cylinder 24 and a cam mechanism 25, and the front presser can be crimped onto the barrel by driving the air cylinder 24.
It is superior to manual methods in that it is easier to work with.

However, in all of the above conventional structures, the front presser simply presses the front body of the shirt, so when the hot plate is next crimped, the wrinkles on the front body surface are not stretched out. It may be pressed in That is, 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, which required extra work and caused the front presser to become hot. There is a problem with the risk of burns due to contact with the tools.

In addition, when the hot plate is crimped, the front presser does not move and remains pressed against the shirt, so the front presser 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 that it is not possible to obtain

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

[Means for solving problems]

In order to solve the above-mentioned problem, the present invention includes a first cylinder device that is vertically expandable and retractable and is swingably attached to the front lower end of the torso stand.
A second cylinder device is installed between the first cylinder device and the front lower end of the torso stand, and the first cylinder device and the second cylinder device are connected to the piston rod of the first cylinder device while the second cylinder device is extended. and the front presser is attached to the tip of the piston rod of the first cylinder device, and the front presser faces the lower part of the front body of the shirt when the piston rod is extended. The position of the piston rod is set so as to be located below the crimping range of the hot plate when the piston rod contracts.

[Effect]

Before starting the press, extend the first cylinder device,
Place the front presser in a position facing the torso stand, and in that state cover the torso stand with the shirt. Thereafter, the second cylinder device is operated, the first cylinder device is swung toward the upright position, and the front presser is crimped onto the front body of the shirt. Next, when the first cylinder device is contracted while the second cylinder device is extended by actuation of the actuating means, the front presser moves downward while keeping the shirt pressed against the body stand. For this reason, the shirt is tensioned vertically and wrinkles on the surface are smoothed out. In this state, the front and rear surfaces of the torso are pressed together using a hot plate to press finish the shirt. In this case, since the front presser is located below the crimping range, no crimping marks from the front presser will be left on the shirt.

〔Example〕

Embodiments of this invention are shown in attached Figures 1 and 5 below.
This will be explained based on the diagram.

As shown in Fig. 1, the torso 1 consists of a base plate 2 and a pair of air bags 3, 3' attached to both sides of the base plate 2, and is mounted on the upper part of a support frame 4 whose interior becomes a passage for hot air to the air bags. Mounted upright.

A first cylinder device 6 that extends and contracts in the vertical direction is attached to the front surface of the support frame 4 via a shaft 5 so as to be swingable in the front and back directions, and a front presser 7 is attached to the tip of the piston rod 6a. is installed.

As shown in FIGS. 2 and 5, the front presser 7 has a square shaft 7a connected to the piston rod 6a,
It consists of a presser bar 8 assembled in a T-shape to the square shaft 7a, and anti-slip layers 8a are provided on both end surfaces of the presser bar 8 by wrapping rough surface tape or the like.

The expansion and contraction stroke of the first cylinder device 6 is as follows:
When the piston rod 6a is extended, the presser rod 8
When the piston rod 6a contracts to a position opposite to the lower part of the front body of the shirt A placed on the torso stand 1, the presser rod 8 comes to a position below the crimping range of the hot plates 13, 13 to the torso stand 1. Set it as follows.

On the other hand, a second cylinder device 9 extending in the front-rear direction is rotatably attached to the lower part of the support frame 4 via a pin 11, and the tip of the piston rod 9a is
It is rotatably connected to the lower end of a link plate 10 connected to the first cylinder device 6 by a pin 12. The second cylinder device 9 and the first cylinder device 6 are
They are operatively connected to each other by actuating means such as pneumatic or hydraulic sources. That is, when the piston rod 6a of the first cylinder device 6 is extended, the piston rod 9a of the second cylinder device 9 is extended, and the front presser 7 is pressed against the barrel stand 1. , the piston rod 6a of the first cylinder device 6 while the second cylinder device 9 is extended.
are linked to contract. Note that the tip of the piston rod 9a may be directly connected to the lower end of the first cylinder device 6.

This embodiment has the above-mentioned configuration, and before the press starts, the first cylinder device 6 is set in an extended state and the second cylinder device 9 is set in a contracted state, as shown in FIG. In this state, the presser bar 8 of the front presser 7 is located away from the body stand 1, and the trunk of the shirt A can be easily mounted between the body stand 1 and the front presser 7.

After the shell A is placed on the torso stand 1, the piston rod 9a of the second cylinder device 9 is extended by, for example, activation of a foot switch, and the first cylinder device 6 is swung in front of the torso stand 1. As a result, the presser bar 8 of the front presser is pressed against the bodice stand 1, as shown by the chain line in FIG.

Next, when the front presser 7 presses the front body of the shirt A to the body stand 1, the actuating means is activated and the first cylinder device 6 contracts, as shown by the solid line in FIG. While crimping 8 to the shirt A, move it downward. As a result, the front body of the shirt A is strongly stretched downward, and the wrinkles on the surface are smoothed out.

Retraction of the piston rod 6a of the first cylinder device 6 is stopped when the presser bar 8 is positioned below the movement range of the hot plate 13, and in this state the presser bar fixes the front body of the shirt. Next, the body stand 1 is moved to the press position of the shirt press machine, and as shown in FIG. 4, a hot plate 13 is pressed to perform a press finish. This pressing finish, for example, involves first lightly pressing the front hot plate onto the shirt, then slightly inflating the air bladder, and then gently pressing the rear hot plate.
Thereafter, both hot plates are strongly pressed together, and the air bag is strongly inflated to press the entire shirt to the hot plates.

When the press finishing is completed and the barrel stand moves to the press setting position, the second cylinder device 9 is retracted to move the presser bar 8 away from the sheet A, and then the first cylinder device 6 is extended. The press is then returned to the state shown in FIG. 2 before the start of the press.

Note that the front presser 7 may also be a T-shaped spring as shown in FIG.

Further, since the first cylinder device 6 needs to have a long expansion and contraction stroke, for example, a telescopic cylinder in which the piston is formed in multiple stages in the expansion direction may be used.

〔Effect of the invention〕

As described above, in this invention, after the front presser is crimped to the front body of the shirt and pressed against the torso,
By moving it downward to make the front section more taut, it is possible to press finish the shirt with the wrinkles fully stretched out, allowing for accurate and stable press finishing, while also making it easier to press than before. Since the operator does not have to pull the bottom edge of the shirt to smooth out wrinkles, highly efficient and safe press work can be performed.

Also, when crimping the hot plate, the front presser can be moved downward to remove it from the crimping range.
It is possible to eliminate the crimping marks of the front presser from the finished surface of the shirt, resulting in a beautiful finish.
