BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning treatment facility for continuously cleaning cabinet towels and the like which are mainly used in washrooms of hotels and restaurants.

[0002]

2. Description of the Related Art FIG. 9 shows a conventional cleaning processing facility, in which a continuous supply device 101, a storage device 102, a cleaning device 103, a rinsing device 104 and a drying device 105 are arranged along a conveyance path.

The storage device 102 has a "V" shape and stores a cleaning liquid. The cleaning device 103 is composed of a pair of car rotors 110 arranged vertically and a water jet nozzle 111 facing each car rotor 110. In the rinsing device 104, a plurality of pairs of upper and lower conveying rollers 112 are arranged at intervals in the front-rear direction, and a water pipe 113 faces between the front and rear rollers from above, and from a hole formed in the water pipe 113, Water is dropped on the surface of the cloth T being conveyed.

When carrying out the cleaning operation, the used roll-shaped towel T is stored in the pocket 115 of the continuous supply device 101, and the starting end of the towel is sewn to the end of the previous towel by a sewing machine to install the equipment. Get up and running.

Towel T pulled out from the pocket 115
Are supplied into the storage device 102 by the supply roller 117 of the continuous supply device 101. In the storage device 102, an appropriate number of towels are dipped in the cleaning liquid and are stored in a zigzag shape.

The communication pipe 11 rises from the storage device 102.
8 into the cleaning device 103 and the cleaning device 1
In 03, the surfaces of the upper and lower car rollers 110 are conveyed in an S-shape, and hot water is dripping (dripping) from each nozzle 111 in the middle of the conveyance to wash both front and back surfaces of the towel being conveyed.

In the rinsing device 104, the transport roller 112 is used.
The residual cleaning liquid is removed by water dripping from above while being transported by.

[0008]

The cleaning device 103 shown in FIG.
In the inside, it is not possible to sufficiently remove dirt by simply dripping (dripping) warm water on the surface of the towel T soaked with the cleaning liquid. Also, the warm water is applied to the towel T in contact with the surface of the car roller. Dripping (drip off)
Therefore, dirt or the like may remain on the towel portion of the car rotor 110 corresponding to the non-mesh holes.

When the cleaning liquid is stored in the storage device 102 located in the middle of the continuous transfer line starting from the continuous supply device 101 and the cleaning liquid is dipped in the storage device 102, the storage amount of the storage device 102 is limited. Because there is
It is not possible to take a sufficient dipping time, for example, about 5 minutes, and the short dipping time cannot sufficiently infiltrate the cleaning liquid. Therefore, as described above, the cleaning mechanism is insufficient and the cleaning effect cannot be improved by simply dripping (dripping) warm water in the cleaning device 103.

In the rinsing device 104, since the cleaning liquid is removed by dropping water, the cleaning liquid may remain.

The cleaning work process will be described. (1) In FIG. 2, a roll-shaped towel T having a width of 20 cm (or 27 cm) and a length of about 20 m is used, and a plurality of these used roll-shaped towels T are stored in the container 11. At the same time, this container 11 is placed on a pallet 12 in 6 boxes and 2 stages, and immersed in each liquid tank 10 while being placed on the pallet 12. After soaking for about 3 hours, the pallet 12 is taken out of the liquid tank 10 and left for about 1 hour to drain water.

(2) An operator takes out the rolled towel T from the container 11 and sets it in the pocket 16 of the continuous feeding device 1. Pocket 1 at the beginning of the rolled towel T
6 Pull out to the outside, guide it onto the guide plate 17 through the optical sensor 21, and sew it to the end of the towel T that remains on the guide plate 17 with the sewing machine 18.

When the towel is not present in the equipment when the equipment is used for the first time, the dummy towel for feeding is set in the transport path from the continuous feeding device 1 to the winding device 7. Then, the starting end of the next rolled towel T is sewn to the end of the dummy towel T.

(3) By rotating the supply roller 15, the towel is pulled out from the pocket 16 and supplied into the storage device 2. When the sensor 21 detects the end portion (break) of the towel T, the supply roller 15 stops. Then, the next towel T is set in the pocket 16 and its starting end is connected to the ending end of the previous towel T. In this way, the towels are continuously connected, and the storage unit 26
A suitable number (for example, about 7) of towels are accumulated in a zigzag shape.

(4) When the accumulation of the appropriate number is completed, the entire line is operated. Even during operation, the towel T in the pocket 16 is sequentially replaced as described above, and the feeding device 1 is continuously operated.
Supply towels from.

(5) The towels T accumulated in the accumulating section 26 are supplied to the cleaning device 3 through the connecting pipe 27, and are moved backward on the conveying surface of the water tank 30 0.3 cm to 1.0 cm below the water surface. Be transported to. During transportation, the towel T is vibrated at high speed by sequentially contacting the lower tip oscillating portion 31a of the ultrasonic transmitter 31 which is vibrating as shown in FIG. That is, it is washed in water in which the washing liquid is dissolved as if it were hit by ultra-high speed, and the dirt is effectively removed.

(6) In the rinsing device 4, the towel T is conveyed obliquely rearward by the conveying roller 39, and is rinsed with high-pressure jet water from the high-pressure water jet nozzle 45 at two places on the way, and then the neutralizing agent is supplied. Nozzle 41 of tube 41
The cleaning liquid remaining in the towel is neutralized by the neutralizing liquid sprayed from a.

(7) In the drying device 5, the surfaces of the upper and lower drying drums 48 and 49 are spirally wound several times along the S-shaped conveying path as shown in FIG.
It is dried by the heat of 8,49.

After drying, in the second accumulating device 6 of FIG. 7, the towel T that has been dried by the driving roller 65 for feeding is used.
Is sent positively to accumulate a certain amount. The accumulated towels T are sequentially wrinkled by a wrinkle stretching mechanism 67, and then wound around a winding shaft 69 which is rotationally driven via a roller 68.

During the winding operation, the next towel T is detected by the sensor 70.
The winding shaft 69 stops when it detects the seam portion between and. After the stop, the sewing thread of the seam between the towels is pulled out, the roll-shaped towel T is pulled out from the winding shaft 69 in the axial direction, the starting end of the next towel T is wound around the winding shaft 69 several times, and the winding shaft is wound. 69 is driven to rotate again, and the next towel T is wound up.
