Description

Description: TECHNICAL FIELD The present invention relates to a roll finishing machine for drying and press-finishing laundry that has been washed and dehydrated, and a method for automatically dehumidifying the roll finishing machine at the end of work. Regarding

[Conventional technology]

A roll finishing machine is known as an apparatus that press-finishes sheets and yukata that have been washed while drying. This kind of roll finishing machine presses and rotates a plurality of rolls arranged side by side on the iron to heat the dehydrated laundry sent from one side while applying pressure between these rolls and the iron. Sequential feeding is performed, drying and press finishing are performed in the process of passing between these rolls and the iron, and then the other is fed.

By the way, in this type of roll finishing machine, the water discharged from the laundry during operation is adsorbed by the pad portion on the roll peripheral surface, and the laundry is not dried when the amount of water contained in the pad portion increases, The finish is not good. For this reason, conventionally, the inside of the roll is connected from the hollow rotating shaft to a moisture exhaust duct via a moisture exhaust fan, and the moisture adsorbed on the pad portion on the peripheral surface of each roll is forcibly sucked by the moisture exhaust fan. It is designed to be discharged from the moisture exhaust duct.

Further, when the operation is terminated, if each roll is left in contact with the trowel, the surface of the roll in contact with the trowel is partially heated by the residual heat of the trowel, causing stains here, There is a problem such as partial heat deterioration of the roll,
In order to prevent this, each roll is raised by a cylinder or the like and separated from the iron.

[Problems to be solved by the invention]

By the way, conventionally, when the operation of the roll finishing machine is stopped at lunch break or at the end of work, the rotation of the roll is stopped when the end button is pressed, and the exhaust fan is also stopped. After these stoppages, a cylinder or the like was manually operated to raise each roll and separate it from the iron.

However, according to such a stopping method, when the end button is pressed, the roll and the dehumidifying fan are immediately stopped, so that the water contained in the pad portion of the roll is not sufficiently removed and the pad portion is not covered with water. There were problems such as residual stains and stains on the laundry when it was used next time.

In addition, after the rolls and the dehumidifying fan were stopped, each roll was raised manually and separated from the iron,
There was also a drawback that required time and effort.

The present invention is intended to provide an automatic dehumidifying method for a roll finishing machine, which can automatically remove water (moisture) from a roll when stopped and can automatically separate the roll from the iron. To do.

[Means for solving problems]

According to the present invention, when the end button is pressed, the roll is rotated at a low speed for a predetermined time while continuing to drive the dehumidifying fan, and thereafter, the rotation of the roll is stopped to separate each roll from the iron. Characterize.

[Action]

According to the present invention, after the end button is pressed, the dehumidifying fan continues to drive and the roll is rotated at a low speed for a predetermined time, so that the pad portion of the roll is heated by the residual heat of the iron during this time, and the low speed Since the entire circumference of the roll pad portion is evenly heated, the moisture contained in the roll pad portion is evaporated and discharged by the moisture exhaust fan. Therefore, no water remains on the roll. Moreover, after this, the roll is automatically raised, so that the roll does not receive the residual heat of the iron and partial heat deterioration is prevented.

And the trowel 2 and is sequentially sent to the rear side to be sent to the take-out table 6. When the laundry is sandwiched between the rolls 4 ... And the iron 2, it is dried by the heat of the heater 3 and is pressed by the sandwiching pressure of these.

The other protruding shaft 10b is a hollow shaft.
Is a dehumidification fan via the flexible hose 20 shown in FIG.
Connected to 21. The moisture exhaust fan 21 is driven by a fan motor 22 and is connected to a common moisture exhaust duct 23. When the moisture exhaust fan 21 is driven, the air in the inner space of the roll 4 is sucked by the moisture exhaust fan 21 through the hollow shaft 10b and the flexible hose 20 and is exhausted through the common moisture exhaust duct 23. For this reason, the water absorbed by the pad 8 of the roll 4 will not be absorbed by the dehumidifying fan.
It is being excluded by 21.

An operation panel 25 is installed on the side of the supply conveyor 5, and various operation indicators, operation buttons and an emergency stop button (not shown) are provided on the operation panel 25, and an end button 26 is provided. is set up. When the end button 26 is pressed, the variable speed motor 17, the air cylinders 12a and 12b corresponding to the lifting drive device, and the fan motor 22 of the moisture exhaust fan 21 are controlled as follows. That is,
In the circuit configuration diagram shown in FIG. 6, the end button 26 is a PBX.
And 27 is a motor low speed rotation timer. This motor low speed rotation timer 27 rotates the variable speed motor 17 at a low speed (5 m / min or less) for about 10 minutes and stops it. 28,29,30,31 are operation timers of solenoid valves (not shown) for extending and expanding the air cylinders 12a, 12b for roll up, respectively, 28 is for the 4th roll, 29 is for the 3rd roll, 30 is for the second roll and 31 is for the first roll. The operation timer 28 for the 4th roll is
The motor low-speed rotation timer 27 operates 5 seconds after the end of operation, the third stage roll operation timer 29 operates 15 seconds after the fourth stage roll operation timer 28 ends, and the second stage roll operation timer 30 is the operation timer for the third roll
The operation is performed 15 seconds after the operation of 29 is completed, and the operation timer 31 for the first stage roll is operated 5 seconds after the operation of the operation timer 30 for the second stage roll is completed. The first-stage roll 4 is a roll close to the supply conveyor 5 side.
It is a step roll.

Reference numeral 32 is a fan motor operation timer. This fan motor operation timer 32 is the operation timer for the first-stage roll 31.
After the operation is completed, the fan motor 22 is operated for about 10 minutes and then stopped.

The operation of the roll finishing machine having such a configuration will be described with reference to the timing explanatory diagram shown in FIG.

During operation of the roll finishing machine, the air cylinders 12a and 12b as the lifting drive devices are contracted to lower the rolls 4 ... And the variable speed motor 17 is rotated at a high speed and the fan motor 22 is driven. The moisture exhaust fan 21 is being driven. Therefore, when the laundry is placed on the supply conveyor 5, the laundry is sandwiched between the rolls 4 ... And the trowel 2 and sequentially sent to the rear side, and in the process of receiving the heat of the heater 3, it is dried, and It is pressed by these clamping pressures and sent out to the take-out table 6.

When the laundry is sandwiched between the rolls 4 ... And the iron 2, the water impregnated in the laundry is pushed out, and this water is absorbed by the pad 8 of the rolls 4. Further, the vapor evaporated from the laundry is also absorbed by the pads 8 of the rolls 4. Since the inner space of the roll 4 is connected to the moisture exhaust fan 21 through the hollow 10b and the flexible hose 20, the moisture absorbed by the pad 7 by the moisture exhaust fan 21 driven by the fan motor 22 is absorbed. Moisture is sucked from the laundry through the ventilation holes 7 ... And discharged through the common moisture exhaust duct 23. Therefore, the pad 7 of the roll 4 is kept in a dry state to some extent to enhance the drying efficiency of the laundry.

Then, when the roll finishing machine is stopped at lunch break or at the end of work, the end button 26 is pressed instead of the emergency stop button.

Then, the motor low speed rotation timer 27 shown in FIG.
Rotate at low speed (5m / min or less) for about 10 minutes, then stop.

When the operation of the motor low speed rotation timer 27 ends, 4
The operation timer 28 for the third roll is activated, and after this operation, the air cylinders 12a, 12b for raising the fourth roll are extended after 5 seconds. Therefore, the fourth roll is raised.

After the operation of the operation timer 28 for the fourth roll is completed, the operation timer 29 for the third roll is activated, and the operation timer 29 for the third roll is the air cylinders 12a, 12b for raising the third roll 15 seconds later. And the third roll 4 is raised.

After the operation of the operation timer 29 for the third roll is completed, the operation timer 30 for the second roll is activated, and the operation timer 30 for the second roll is set to the air cylinders 12a, 12b for raising the second roll 15 seconds later. And the second roll 4 is raised.

After the operation of the second-stage roll operation timer 30 is completed, the first-stage roll operation timer 31 is activated, and the first-stage roll operation timer 31 is set to the first-stage roll raising air cylinders 12a, 12b after 5 seconds. And the first-stage roll 4 is raised.

After the operation timer 31 for the first-stage roll is completed, the fan motor operation timer 32 is operated, and the fan motor operation timer 32 stops the fan motor 22 after about 10 minutes. That is, even if the end button 26 is pressed, the fan motor 22 continues to be driven until this stop time.

In such a roll finishing machine, when the end button 26 is pressed, the rolls 4 rotate at a low speed without being lifted, so that heat from the heaters 3 is applied to the rolls 4 to accelerate the drying of the rolls 4. Be done. In particular, since the rolls 4 are rotated at a low speed at this time, the periphery of the rolls 4 is uniformly heated, and the operation of the moisture removal fan 21 is continued, so that the rolls 4 are quickly dried.

After that, the variable speed motor 17 is stopped and the rolls 4 ... Are automatically raised, so that no special manual operation is required. The rolls 4 ... Are safe because they are lifted after the rotation is stopped. Moreover, in the case of the present embodiment, the rolls are raised from the fourth roll 4 to the first roll 4 in order, so that the operator can easily confirm. That is, since the worker is near the operation panel 25, when the worker rolls up from the roll on the front side of the worker, the state of the roll on the other side becomes invisible due to the raised roll, but from the roll far from the worker. By raising the rolls in order, it is possible to surely confirm how the rolls are raised.

Finally, when the roll 4 in the first stage rises, the operation of the moisture removal fan 21 is still continued, so that the roll 4 is more reliably dried.

Therefore, water does not remain on the pads 8 of the rolls 4 and the stains are prevented from occurring due to this, and the problem such as stains on the laundry when it is used next is eliminated. The present invention is not limited to the method described in the above embodiment.

That is, in the above-described embodiment, after all the rolls 4 have risen, the operation of the dehumidifying fan 21 for about 10 minutes is continued to change the rolls 4
However, it is also possible to stop the operation of the moisture exhaust fan 21 at the same time when the roll 4 finishes rising, and even in this case, the drying efficiency is improved as compared with the conventional case.

Further, the rolls 4 may be raised at the same time for all the rolls.

〔The invention's effect〕

As described above, according to the present invention, after the end button is pressed, the dehumidifying fan continues to drive and the roll is rotated at a low speed for a predetermined time, so that the pad portion of the roll receives the residual heat of the iron and heats up. Since the roll is rotated at a low speed, the entire circumference of the roll pad portion is evenly heated, so that the moisture contained in the roll pad portion is evaporated and discharged by the moisture removal fan. It Therefore, no water remains on the roll. Moreover, after this, the roll is automatically raised, so that the roll does not receive the residual heat of the iron and partial heat deterioration is prevented.
