Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to roll finishing for drying and press finishing laundry that has been washed and dehydrated, and provides an automatic method for draining moisture from finished rolls at the end of work. Regarding.

[Conventional technology]

2. Description of the Related Art A roll finishing machine is known as a device that press-finishes washed sheets, yukatas, etc. while drying them. This type of roll finishing machine rotates multiple rolls arranged side by side in pressure contact with a trowel, and the dehydrated laundry fed from one side is heated while being pressurized between these rolls and the trowel. The material is fed sequentially, dried and press-finished during the process of passing between these rolls and the iron, and then sent out from the other side.

By the way, in this type of roll finishing machine, the water discharged from the laundry during operation is adsorbed to the butt part on the circumferential surface of the roll, and if the amount of water contained in this butt part increases by 1, the laundry will not be dried. The quality of the finish deteriorates. For this reason, in the past, the inside of the roll was connected from a hollow rotating shaft to a dehumidifying duct via a dehumidifying fan, and the moisture adsorbed on the butt part of the circumferential surface of each roll was forcibly sucked out by the dehumidifying fan. It is designed to be discharged from the humidity duct.

In addition, if each roll is left in contact with the iron after the operation is finished, the surface of the roll that was in contact with the iron will receive residual heat from the iron and be partially heated, causing oozing or rolling. There are problems such as partial heat deterioration,
To prevent this, each roll is raised using a cylinder or the like and separated from the iron.

[Problem to be solved by the invention] Conventionally, when stopping the operation of a roll finishing machine at lunch break or at the end of the work day, pressing the end button stops the rotation of the rolls and also stops the dehumidification fan. It was like that. After these stops, cylinders and the like are operated manually to raise each roll and separate it from the iron.

However, according to this stopping method, when the end button is pressed, the roll and the dehumidification fan are immediately stopped, so the moisture contained in the butt part of the roll is not removed sufficiently, and the moisture in the butt part is stopped. There were problems such as residual stains and stains on laundry the next time it was used.

In addition, after the rolls and dehumidification fan stopped, each roll was manually raised and separated from the iron.
It also had the disadvantage of requiring time and effort.

The present invention provides an automatic moisture draining method for roll finishing that can automatically remove moisture (moisture) from the roll when the roll is stopped and can also self-help separate the roll from the trowel. That is.

Means for Solving Problem C] According to the present invention, when the end button is pressed, the rolls are rotated at a low speed for a predetermined time while the dehumidification fan continues to be driven, and then the rotation of the rolls is stopped and each roll is rotated. It is characterized by being separated from the iron.

[Effect]

According to the present invention, after pressing the end button, the roll is rotated at low speed for a predetermined time while the dehumidification fan continues to drive, so during this time the butt part of the roll is heated by the residual heat of the iron, and Since the roll is rotated, the entire circumference of the butt part of the roll is heated evenly and evenly, so that the moisture contained in the butt part of the roll is evaporated and discharged by the dehumidification fan. Therefore, no moisture remains on the roll. Moreover, since the roll is automatically raised after this, the roll is not exposed to residual heat from the iron, and partial thermal deterioration is also prevented.

[Actual example]

The present invention will be described below based on an embodiment shown in the drawings.

1 to 5 are diagrams showing the schematic configuration of a roll finishing machine, in which 1 is a base, 2 is a trowel with a wave-shaped curved surface, and 3 is a trowel with a waveform curved surface.
... is a heater installed in the concave part of the corrugated curved surface of iron 2, 4
. . . are rolls facing each of the heaters 3 .

5 is a laundry supply conveyor, and 6 is a take-out table.

The rolls 4 are located between the supply conveyor 5 and the take-out table 6 and are arranged side by side in the horizontal direction, and a bat 8 having a large number of ventilation holes 7 is provided on the outer peripheral surface. .

These rolls 4... have shafts 10a protruding from both ends.

10b extends through a side wall 9.9 erected on the machine stand, and these protruding shafts 10a, 10b are supported by bearings 11a, 11b, respectively.

These bearings 11a and 11b are supported by air cylinders 12a and 12b, which correspond to the lifting drive device of the present invention. Therefore, the air cylinders 12a, 1
Due to the stretching action of 2b, the roll 4 is raised as shown by the imaginary lines in FIGS. 3 and 4.

The tip of one of the protruding shafts 10a is connected to a reducer 13, and this reducer 13 is connected to a drive pulley 14 at an eccentric position.
is attached. Note that the reducer 13 is rotatably supported by a bracket 15 erected on the base 1 at the above eccentric position. For this reason, the air cylinders 12a, 12
When the roll 4 is raised by the elongation action of b, it is raised while rotating around the eccentric position as the center of rotation.

Each drive pulley 14 provided on the roll 4 has a belt 16 passed between adjacent ones, and the drive pulley 14 located at the left end in FIG. A belt 19 is passed between the pulley 18 and the pulley 18. The motor 17 is a variable speed motor;
Due to the rotation of each belt 19, 16..., drive pulley 1
4, the rolls 4... are rotated synchronously in the same direction. For this reason, the laundry placed on the supply conveyor 5 is sandwiched between the rolls 4 . When the laundry is caught between these rolls 4... and the iron 2,
It is dried by receiving heat from the heater 3 and pressed by these clamping pressures.

The other protruding shaft 10b is a hollow shaft, and this hollow shaft 10b is connected to a dehumidification fan 21 via a flexible hose 2o also shown in FIG. The dehumidifying fan 21 is driven by a fan motor 22, and the common dehumidifying flexible hose 20
through the common humidity drainage duct 2.
It is discharged through 3. Therefore, bat 8 of roll 4
The moisture absorbed by the air is removed by a dehumidification fan 21.

An operation panel 25 is installed on the side of the supply conveyor 5, and this operation panel 25 is provided with various work indicator lights, operation buttons, and an emergency stop button (not shown), and an end button 2G. 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 dehumidification fan 21 are controlled as follows. That is, in the circuit configuration diagram shown in FIG. 6, the end button 26 is shown as a PBX, and
7 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 then stops it. 28, 29, 30, and 31 are operation timers for electromagnetic valves (not shown) that extend and operate the roll lifting air cylinders 12a and 12b, respectively; 28 is for the fourth roll, 29 is for the third roll, 30 is for the second stage roll, and 31 is for the first stage roll. The activation timer 28 for the 4th roll starts operating 5 seconds after the motor low speed rotation timer 27 ends, and the activation timer 29 for the 3rd roll starts 15 seconds after the activation timer 28 for the 4th roll ends. The operation timer 30 for the second roll operates 15 seconds after the operation timer 29 for the third roll ends, and the operation timer 31 for the first roll operates as the operation timer 30 for the second roll. It is designed to operate 5 seconds after the end of Saku 11J. Note that the first roll 4 is a roll similar to the 5 examples of the supply conveyor, and the following rolls are sequentially removed from the take-out table 6.
From the side, there are 2nd to 4th rolls.

32 is a fan motor operation timer, and this fan motor operation timer 32 operates so as to operate the fan motor 22 for about 10 minutes and then stop it after the operation of the first roll operation timer 31 is completed.

The operation of the roll finishing machine with such a configuration will be explained with reference to a timing diagram shown in FIG. 7.

During roll finishing operation, each air cylinder 12a, 12b as a lifting drive device is contracted and the rolls 4... are lowered, and the variable speed motor 17
is being rotated at high speed, and a fan motor 22 drives a dehumidifying fan 21. Therefore, when the laundry is placed on the supply conveyor 5, the laundry is distributed between each roll 4.
. . . and the iron 2, and are sequentially sent to the rear, and in the process are dried by the heat of the heater 3, are pressed by the pressure of these clamps, and are sent to the take-out table 6.

When the laundry is caught between roll 4 and iron 2,
The water impregnated in the laundry is pushed out, and this water is absorbed into the batts 8 of the rolls 4...

Further, steam evaporated from the laundry is also absorbed by the batts 8 of the rolls 4 . The internal space of the roll 4 is connected to a dehumidifying fan 21 via a hollow hollow shaft W flexible hose 20, so that the dehumidifying fan 21 driven by a fan motor 22 absorbs moisture into the vat 7. Also, moisture is sucked in from the laundry through the ventilation holes 7 . . . and discharged through the common moisture drainage duct 23. For this reason, the batt 7 of the roll 4 is kept in a certain degree of dryness, thereby increasing the efficiency of drying the laundry.

Therefore, when stopping the roll finishing machine during lunch break or at the end of the workday, the user presses the end button 26 instead of the emergency stop button.

Then, the motor low speed rotation timer 27 shown in FIG. 6 is activated, and the 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 then stops it.

When the operation of the motor low speed rotation timer 27 is completed,
The operation timer 28 for the fourth stage roll is activated, and after 5 seconds due to this operation, the air cylinder 12a for raising the fourth stage roll is activated.
, 12b are actuated to extend. Therefore, the fourth stage roll 4 is raised.

After the operation of the fourth roll operation timer 28 is completed, 3
The third roll operation timer 29 is activated, and after 15 seconds, the third roll raising air cylinders 12a and 12b are extended and the third roll 4 is raised. Ru.

After the operation of the third-stage roll operation timer 29 is completed, the second
The second roll operation timer 30 is activated, and after 15 seconds, the second roll raising air cylinders 12a and 12b are extended and the second roll 4 is raised. Ru.

After the operation of the second roll operation timer 30 is completed, 1
The operation timer 31 for the tier rolls is activated, and after 5 seconds, the operation timer 31 for the tier 1 rolls extends and operates the air cylinders 12a and 12b for raising the tier 1 rolls, so that the tier 1 rolls 4 are lifted. Ru.

After the operation timer 31 for the first stage roll is activated, the fan motor operation timer 32 is activated, and this 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 it stops.

In such a roll finishing machine, the end button 26
When is pressed, the rolls 4 are rotated at low speed without being lifted, so heat from the heaters 3 is applied to the rolls 4, thereby promoting drying of the rolls 4.

In particular, since the rolls 4 are rotated at low speed at this time, the surroundings of the rolls 4 are evenly heated, and the dehumidification fan 2
Since the operation of No. 1 is also continued, the rolls No. 4 are quickly dried.

After that, the variable speed motor 17 is stopped and each roll 4.
... is automatically raised, so no special manual operation is required. It should be noted that each roll 4 is safe because it is raised after it stops rotating. Moreover, in the case of this embodiment, 4
Since the rolls 4 are raised in order from the rolls 4 on the first stage to the rolls 4 on the first stage, confirmation by the worker is easy. In other words, since the worker is located near the operation panel 25, if the worker is lifted from the roll on the side near him, he will not be able to see the status of the roll on the other side due to the raised roll, but it will be difficult to see the status of the roll on the other side than the roll far from the worker. By raising the rolls in sequence, it is possible to reliably check how the rolls are raised.

When the roll 4 of the first stage is finally lifted, the operation of the dehumidifying fan 21 is continued, so that the roll 4 can be dried even more reliably.

Therefore, moisture does not remain in the vat 8 of the rolls 4, and stains caused by this are prevented, and problems such as stains on the laundry when used next time are eliminated. Ru.

Note that the present invention is not limited to the methods described in the above embodiments.

That is, in the above embodiment, after all the rolls 4 have been raised, the operation of the dehumidifying fan 21 is continued for approximately 10 minutes to further ensure the drying of the rolls 4. The operation of the dehumidifying fan 21 may be stopped at the same time as the drying is finished, and even in this case, the drying efficiency is improved compared to the conventional method.

Furthermore, the rolls 4... may be raised simultaneously by raising all the rolls at the same time.

〔Effect of the invention〕

As explained above, according to the present invention, after pressing the end button, the roll is rotated at a low speed for a predetermined period of time without the dehumidification fan continuing to drive, so that the butt part of the roll receives residual heat from the iron during this time. Since it is heated and rotated at low speed, the entire circumference of the butt part of the roll is heated evenly and evenly, so that the moisture contained in the butt part of the roll is evaporated and discharged by the dehumidification fan. be done. This prevents moisture from remaining on the roll. Moreover, since the roll is automatically raised after this, the roll is not exposed to residual heat from the iron, and partial thermal deterioration is also prevented.
