Because 62 rotates in the direction orthogonal to
The basket 30 sequentially sent by the feed roller mechanism 150
The first basket 300 is pushed out from the end of the receiving portion 160 by the pressing force of the zeros so as not to fall.

Subsequently, the immersion apparatus 10 having the above-described configuration is used.
The operation of 0 will be described. First, the basket 300 accommodating the tableware 301 taken out of the container 400 is sequentially put in from the inlet 111 of the immersion tank 110. At this time,
With the opening 302 of the basket 300 facing upward, the input port 11
Start from 1. Thus, the basket 300 inserted from the insertion port 111 is rotated by the rotating roller 121 of the roller mechanism 120.
As a result, it moves to the bottom side of the immersion tank 110 by its own weight.

Next, the basket 300 that has moved to the bottom side of the immersion tank 110 is sequentially conveyed by the conveyor mechanism 130 to the back side of the immersion tank 110. At this time, the transport speed by the conveyor mechanism 130 is very slow, and the tableware 301 in the basket 300 is sufficiently immersed in the hot water in the immersion tank 110.

At about the same time when the basket 300 located at the head is pushed into the accommodation portion 141 of the elevator mechanism 140, the rotation of the stopper prevents the basket 300 containing the next tableware 301 from being conveyed.

In this state, when the elevator mechanism 140 rises, the bottom side of the basket 300 is lifted by a plurality of roller bodies 145 and 146 disposed to face the frame body 142. At this time, these roller bodies 1
Since 45 and 146 are separated so as not to contact the endless belts 134 of the conveyor mechanism 130, the lifting operation of the elevator mechanism 140 is performed without any trouble.

At this time, as the basket 300 is pulled up from the hot water in the immersion tank 110, the water and the like attached to the tableware 301 drip by its own weight.

When the elevator mechanism 140 moves up to the upper position, the pushing arm 149 rotates about the shaft 148 as a fulcrum, and pushes the basket 300 in the housing 141 of the elevator mechanism 140 toward the feed roller mechanism 150. The extruded basket 300 is provided with the inclined feed roller mechanism 15.

In the feed roller mechanism 150, in order to feed the basket 300 more smoothly,
You may make it give the driving force by a drive mechanism.

Even during the movement of the basket 300 by the feed roller mechanism 150, the water and the like adhering to the tableware 301 drip by its own weight.

When the push-out of the basket 300 is completed and the elevator mechanism 140 is lowered to the lower position, the stopper is rotated substantially at the same time, and the next basket 300 is fed into the accommodating portion 141 of the elevator mechanism 140 by the conveyor mechanism 130.

At the same time, in a state where the stopper rotates again and the movement of the subsequent basket 300 is restricted, the basket 300 is transferred to the upper roller mechanism 150 side by raising the elevator mechanism 140 in the same manner as described above. You.

When the basket 300 reaches the receiving section 160 provided at the end of the roller mechanism 150, the receiving section 160 sets the rotating rollers 161 and 162 in the direction orthogonal to the traveling direction of the basket 300. Therefore, the leading basket 300 is pushed out from the end of the receiving unit 160 and held so as not to drop by the pressing force between the baskets 300 sequentially sent by the feed roller mechanism 150.

Therefore, the feed roller mechanism 150
Is sent by the feed roller mechanism 150
By staying on the top, the basket 300 which has been immersed is stored on the feed roller mechanism 150, so that the basket 300 accommodating the tableware 301 taken out of the container 400 is inserted into the input port 111 of the immersion tank 110. , The frequency of stacking the baskets 300 taken out of the container 400 near the inlet 111 of the immersion tank 110 is reduced.

In this state, the receiving unit 160 moves the basket 300
The tableware 3 in the basket 300 on the high-pressure washing machine 200 side.
01 can be transferred.

At this time, the receiving section 160 is provided orthogonal to the feed direction of the feed roller mechanism 150, so that the basket 30 from the inlet 111 of the immersion tank 110 is provided.
The basket 300 is taken out so as not to hinder the operation of putting 0.

At this time, since the water and the like adhering to the tableware 301 are drained during the lifting operation by the elevator mechanism 140 and the movement along the roller mechanism 150, the basket 300 is lifted to the high-pressure washing machine 200 side and the tableware 301 is lifted. When you transfer water, the amount of water on your body is extremely small.

Further, since the attached matter of the tableware 301 is also slightly dropped together with the drainage of the dishware 301 as described above, the amount of the attached matter of the tableware 301 adhered to the body is extremely small, and sanitary work is performed. Not only becomes possible, but the washing operation by the high-pressure washing machine 200 at the subsequent stage is efficiently performed.

Can be arranged side by side with the high-pressure washer 200, so that the empty space beside the high-pressure washer 200 can be effectively used.
Further, the basket 30 transported by the conveyor mechanism 130
Since 0 is held and lifted by the elevator mechanism 140, the lifting space of the basket 300 is minimized.

Furthermore, since the basket 300 conveyed upward by the elevator mechanism 140 slides down to the vicinity of the conveyance start point of the conveyor mechanism 130 by the feed roller mechanism 150, a new drive mechanism for the feed roller mechanism 150 is not required. However, in order to feed the basket 300 more smoothly, a driving force by a driving mechanism may be given to the feed roller mechanism 150.
