In this case, in the conventional machine, the control circuit usually includes a relay, a sequencer, or a microcomputer, and is configured to receive an electric signal from an input switch and output an electric signal to a driving unit.

[0003]

By the way, users of this type of finishing machine are preferred to be inexpensive and have no maintenance cost if they have the same performance and the same quality. Therefore, this type of finishing machine is desirably formed so that the structure can be simplified, the product price can be reduced, and maintenance can be easily performed by the user.

However, in the conventional machine, as described above, the control circuit is formed with a microcomputer and the like, and is equipped with an air circuit such as an air cylinder for operating a press iron and an electric circuit for controlling the pneumatic circuit. Was something. Therefore, according to the conventional machine, the manufacturing cost increases and the product price cannot be avoided.

[0005] In addition, as described above, the conventional machine had two different circuit structures, so that inspection and repair required specialized knowledge in mechanical and electrical systems. Therefore, in the case of the conventional machine, it is difficult for the user to perform the repair in the event of a failure. Therefore, the conventional machine has a problem that the maintenance is inconvenient and the cost of the inspection and repair is relatively high.

Further, in the case of the conventional machine, the electric control circuit is provided as described above. Therefore, according to the conventional machine, it is necessary to cope with the electric characteristics such as the voltage and the frequency of the installation place. Not only was there a risk of electric shock accidents, but there was also a problem that once a power outage occurred, it could not be used.

The present invention has been proposed in view of such problems of the conventional machine. Therefore, the technical problem of the present invention is to simplify the structure of the device, reduce the cost and facilitate the maintenance, form the device so that it can be used without being affected by the electrical characteristics of the installation location, and furthermore, An object of the present invention is to provide a press-finishing machine for clothing which eliminates dangers and can be operated even if a power failure occurs.

2 operation switches S2 and each of these operation switches S
1, a start switch S3 for lowering the cuff press iron 41 or the color press iron 42 by continuing to be pressed together with either one of S1 and S2, and each of these switches is constituted by a manually operated air valve. Is preferable (claim 3).

In this case, since both the cuff press iron 41 and the color press iron 42 do not descend unless the start switch S3 is kept pressed together, each operation switch S
The operator cannot release both hands until the iron comes down from 1, S2 and the start switch S3. Therefore, according to this, there is an advantage that an accident in which a finger or the like is excessively pinched by the press iron 4 can be prevented. Here, the air valve of the manual operation type is the same as the above-described claim 1.

Further, the present invention preferably comprises a timer air cylinder 33 for controlling the press time (claim 4).

In this case, the press time can be controlled by a simple and low-cost mechanism, and unless the operation of the timer air cylinder 33 is completed, the next drive section 3 does not operate. This is because the movement can have reliability. The time setting of the timer air cylinder 33 is specifically achieved by using the speed controller 21 (speed control valve) or a needle valve.

The color air cylinder 32 is for rotating the color press iron 42 in the vertical direction by the expansion and contraction of a rod, and is provided upright at the rear portion of the apparatus main body.

As shown in FIG. 2, the air cylinder 33 for the timer is designed so that the rod expands and contracts in the lateral direction.
It is provided horizontally inside the control panel 6. The end position switch 23 is provided with a timer air cylinder 33.
The air pressure signal is output when the timer air cylinder 33 is pushed by the end of the rod.

Next, the operation of the finishing machine according to this embodiment will be described with reference to FIGS.

First, the operator turns on the input switch 1, and then presses the start switch S3 and the operation switch S1 of the cuff press iron 41. Then, the cuff air cylinder 31 is driven, and the cuff press iron 41 is lowered.

When the cuff press iron 41 is lowered, the holding switch S4 of the cuff press iron 41, which is always on, is turned off. Then, the down switch S5 of the cuff press iron 41 is turned on, and the cuff is press-finished by the cuff press iron 41. In this case, in the finishing machine of the present invention, the operation switch S1 and the start switch S3 of the cuff press iron 41 must be kept pressed (unless the holding switch S4 of the cuff press iron 41 is turned off). The press iron 41 is configured not to descend. This is to prevent the operator from being caught between the ironing board 5 and the finger by the cuff press iron 41.

Next, after the cuff press iron 41 is completely lowered, the operator presses the start switch S3 and the operation switch S2 of the color press iron 42. Then, the color air cylinder 32 and the timer air cylinder 33 are driven.

When the holding switch S6 of the color press iron 42 is turned off, the color press iron 42 descends and finishes the color press. In this case, the pressing time depends on the extension time of the rod of the timer air cylinder 33. That is, the cuff and the collar of the shirt are press-finished until the rod of the timer air cylinder 33 extends and the end position switch 23 is pressed. This time is set to 45 seconds in this embodiment.

After the set time has elapsed, the rods of the cuff air cylinder 31 and the color air cylinder 32 contract, the cuff press iron 41 and the color press iron 42 rise, and a series of press steps is completed. .

Next, a case in which wrinkles on a sleeve of a shirt are partially repaired by using the finishing machine of the present invention will be described.

This reworking is performed by a cuff press iron 41
The upper surface 4 of the cuff press iron 41 is
For example, a sleeve of a shirt is set in 12 and pressed by a color press iron 42. In FIG. 5, the operator first turns on the rework switch S8, and then starts the start switch S3 and the operation switch S of the color press iron 42.
Press 2.

Then, the rod of the color air cylinder 32 extends, and the color press iron 42 descends. When the holding switch S6 of the color press iron 42 is turned off, the timer air cylinder 33 is driven, and the sleeve of the shirt is press-finished for the set time.

When the end position switch 23 is pushed by the rod of the timer air cylinder 33, the rod of the color air cylinder 32 contracts, and the color press iron 42
Rises. The rod of the air cylinder for timer 33 contracts and stops. In the case of the present invention, the reworking operation can be repeated by subsequently pressing the reworking switch S8.

[0039]

As described above, the present invention is formed so that the electric control circuit can be wiped out, automatically controlled only by the air pressure, and press-finished.

Therefore, in the case of the present invention, the structure can be simplified, so that it can be provided at low cost, can be easily maintained, and can be used without being affected by the electrical characteristics of the installation place. It has an excellent effect that it can eliminate the danger of electric shock and can operate even if the power goes out.
