Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a tunnel finisher used for drying and finishing clothes.

[Conventional technology]

Clothes can be ironed to a very beautiful finish by thoroughly smoothing out wrinkles on the surface of the fabric before the ironing process. For this reason, in conventional cleaning operations, washed clothes are dried using a tunnel finisher to smooth out surface wrinkles.

Such a tunnel finisher has a steam chamber and a hot air chamber connected in series, and has a structure in which a chain conveyor with hangers attached at predetermined intervals is installed above both chambers. Clothes hung through hangers are passed through a steam chamber and a hot air chamber, and are dried by blowing out steam and hot air.

The above-mentioned steam room and hot air room have a vertically long entrance/exit for letting hanging clothes in and out, and inside the steam room, there are a plurality of steam blowing nozzles corresponding to the entire vertical length of the vertically long entrance. These machines are now being installed to spray steam onto clothing brought into the room to smooth out wrinkles on the surface.

In addition, tunnel finishers include those with a shielding chamber between the steam room and the hot air chamber, and those with a structure that connects a cold air chamber next to the hot air chamber and blows outside air onto the dried clothes to finish them with cold air. The tunnel finisher in this invention includes all of these structures.

[The problem that the idea attempts to solve]

By the way, conventionally, this type of tunnel finisher has a door at the entrance of the steam room that opens and closes the entrance to isolate it from the outside.
When the entrance door is opened, the steam remaining inside the steam chamber leaks to the outside from the entrance and adheres to the chain conveyor and the sprockets that rotate it. When the steam adhering to the chain conveyor etc. cools down, it falls as dew water and adheres to the clothes suspended from the chain conveyor, causing the clothes to become dirty.

However, in order to eliminate the above-mentioned dew condensation phenomenon, if the entrance and exit of the steam chamber is opened wide to blow out steam, the steam escapes from the steam chamber, causing a temperature drop. Once the temperature is lowered in this manner, a large amount of steam and time are required to bring the inside of the steam chamber into a sufficiently uniform state, resulting in problems that increase costs and reduce work efficiency.

This invention solves the above-mentioned problems and provides a tunnel finisher that prevents leakage of steam from the steam chamber, eliminates temperature drop in the steam chamber, and allows continuous high-efficiency dry finishing. The purpose is

[Means to solve the problem]

In order to solve the above problems, this invention provides a closing means at the inlet and outlet of the steam chamber that allows clothing to pass through but normally closes the entrance and exit, and an air suction means is connected to the upper part of the steam chamber. In addition, the structure includes a control means for operating the air suction means only when the steam blowing and closing means of the steam chamber closes the entrance/exit.

[Effect]

In the above structure, the air suction means is activated at the same time as the steam is blown out in the steam chamber, and the steam that has unevenly finished the clothes is forcibly discharged from the exhaust port in the upper part of the steam chamber. This prevents leakage of steam from the steam chamber inlet and prevents condensation on the chain conveyor and the like.

Further, when the blowing out of steam is stopped with the closing means closing the entrance/exit of the steam chamber, the operation of the air suction means is stopped and the discharge of steam is stopped. This prevents an unnecessary drop in temperature inside the steam chamber while the clothes are not being finished.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in FIGS. 1 and 2, inside the processing box 1, a steam chamber 2, a shielding chamber 4, and a hot air chamber 3 are provided with their inlets and outlets connected in series. For each room 2, 3, 4
An endless chain conveyor 5 passing through the upper part of the processing box 1 and going around the outside of the processing box 1 is provided.

This chain conveyor 5 is horizontally extended by a sprocket 6 and a pulley 7 arranged around the processing box 1.
It is designed to rotate by driving an electric motor 8 connected to.

Further, a plurality of hangers 9 are attached to the chain conveyor 5 at predetermined intervals in the length direction.
The intervals between the hangers 9 are set so that at least one hanger 9 is located in each of the steam chamber 2 and the hot air chamber 3.
The clothes hung via hangers 10 are moved through the center of each chamber 2, 3, and 4 by the movement of the chain conveyor 5.

As shown in FIG. 3, the entrance 2a of the steam chamber 2 is formed in a vertically elongated shape so that clothing can be carried in in a suspended state, and each entrance has a door 11 that almost completely blocks the opening. is installed.

This door 11 is divided into two in the vertical direction, and both the upper door 11a and the lower door 11b can be opened and closed from the center in the lateral direction toward the inside.

Furthermore, a groove 12 through which the chain conveyor 5 is inserted is provided in the upper part of the upper door 11a, so that the chain conveyor 5 can freely rotate regardless of whether the door 11 is opened or closed. This door 11 and a pair of airbags 25 provided in the shielding room 4 described later
constitutes the closure means.

As shown in FIGS. 1 and 2, the steam chamber 2 is
A plurality of sets of two steam pipes 14, 14 are provided along the transport path direction on both sides of the interior, and each steam pipe 14,
A large number of steam blowing nozzles 13 are provided on the side surface of the door 14 to correspond to the entire length of the door 11 in the vertical direction, and to direct toward the clothes passing through the center of the steam chamber 2.

Further, an exhaust port 15 is provided on the front upper surface of the steam chamber 2, an exhaust duct 16 is connected to the exhaust base 15, and an exhaust fan 17 is installed inside the exhaust duct 16. Further, a pipe 18 connected to the outside of the factory is connected to the exhaust duct 16.

In the case of the above structure, the exhaust duct 16 and the exhaust fan 17 constitute air suction means. Note that in the above structure, an exhaust pump or the like may be provided in place of the exhaust fan 17, and the exhaust duct 16 may be replaced with an exhaust pump or the like.
The exhaust fan 17 may be directly attached to the exhaust port 15 by omitting the above.

On the other hand, the upper door 11a and the lower door 11b each have a detection device 19 such as a proximity switch that detects whether they are opened or closed.
As shown in FIG. 4, this detector 19 is connected to a controller 20 that controls the supply of steam to the steam pipe. Further, an actuator 21 of the exhaust fan 17 and a timer 22 for setting the steam blowing time are connected to the controller 20, and the detector 1
The signal of the detection signal timer 22 of No. 9 is configured to serve as the above-mentioned supply stop signal and the activation signal of the actuator 21 of the exhaust fan 17. That is, when the entrance door 11 is opened due to the loading of clothes, steam is blown out from the blow-off nozzle 13 due to the activation of the detector 19, the actuator 21 is turned on, and the exhaust fan 17 is rotated. When the time elapses, the output signal causes the steam blowing to stop, the actuator 21 to turn off, and the exhaust fan 17 to stop. In the above structure, the detector 19, the controller 20, and the timer 22 constitute a control means for operating the air suction means.

Note that the operation of the blowing nozzle 13 of the steam chamber 2 and the hot air blowing of the hot air chamber 3 may be linked with the operation of the chain conveyor 5 that moves the clothes and opens and closes the door 11.

On the other hand, as shown in FIG. 2, the hot air chamber 3 is provided with an air duct 24 equipped with a heating heater 23 on the side, and the hot air is circulated through the duct 24 and into the hot air chamber 3 at the upper part of the duct 24. It is equipped with a fan that blows out hot air to dry clothes.

A pair of airbags 25 are provided in the shielding chamber 4 to partition the steam chamber 2 and the hot air chamber 3, and the clothes are moved by rotating the airbags 25 and passing between them.

This embodiment has the configuration as described above, and its operation will be explained next.

On the hanger 9 outside the processing box 1,
The clothes are lifted up via the hanger 10, and the chain conveyor 5 is rotated to convey the clothes.

When the clothes are carried in through the entrance of the steam chamber 2, the upper door 11a is opened and the detector 19 is activated, causing steam to be released from the blow-off nozzle 13 in the steam chamber 2 as shown in FIGS. 1 and 2. At the same time, the actuator 21 is activated, the exhaust fan 17 rotates, and the inside of the exhaust duct 16 is sucked. In this case, the steam blown out from the blow-off nozzle 13 finishes unevenly finishing the clothes, and then is sucked into the upper exhaust port 15 without heading toward the inlet 2a, and is discharged to the outside through the exhaust duct 16. Therefore, even if the door 11 of the steam room 2 is open, steam does not leak to the outside from its inlet, so no water condenses on the chain conveyor 5, sprocket 6, etc.

During the uneven finishing in the steam room 2, the hot air room 3
Then blow out hot air to dry the clothes.

When the set working time is over and the timer 22 is activated, the blowing nozzle 1 is activated in the steam chamber 2.
3 stops blowing out steam, the actuator 21 is turned off, and the exhaust fan 17 is stopped. Therefore, the steam remaining in the steam chamber 2 is not discharged from the exhaust port 15 and remains inside, thereby preventing the temperature inside the room from decreasing during the standby state. Therefore, the next garment to be brought in will be finished in the high-temperature steam chamber 2, and the loss of heat due to forced steam exhaust can be suppressed to a low level.

When the above process is completed, the chain conveyor 5 is moved to carry out the finished garment, carry the next garment into the processing box 1, and repeat the above finishing operation.

The above finishing work can be performed automatically by starting each process in succession,
Alternatively, each step of each cycle may be manually operated.

Further, the tunnel finisher of this invention can be applied not only to one having a steam chamber and a hot air chamber as shown in the figure, but also to one having a cold air chamber behind the hot air chamber.

[Effect of idea]

As explained above, this invention provides an exhaust port and an air suction means at the top of the steam chamber, and only when the steam chamber's steam outlet and the steam chamber entrance/exit are closed, steam is forced to the exhaust port. This prevents excess steam from leaking from the steam chamber, preventing condensation on chain conveyors, etc., and also prevents unnecessary steam leaks and lowers the temperature inside the steam chamber. can be eliminated.

Therefore, it is not necessary to stain clothes due to adhesion of dew condensation water, and there is an effect that efficient drying work can be carried out continuously.
