Then, sprockets 52 are fixed to the upper ends of the rotary shafts 1 projecting upward from the top plate 51, respectively. The drive chain 56 is suspended.

As shown in FIG. 9, the thus configured tableware separator A is assembled in a cleaning labor-saving system. In FIG. 9, reference numeral 57 denotes an immersion tank for immersing the tableware in the basket 58 in order to soften the cooked rice or the like adhering to the used tableware. A table 60 is a washing machine for washing the dishes w, which are sequentially separated and dropped from the tableware separator and transported, with a fountain.

Next, the operation of the tableware separator A configured as described above will be described.

The moving device 3 is operated according to the diameter of the dish w that is being softened by the immersion tank 57, and the internal space formed by the three rotary shafts 1 is adjusted.

Now, it is assumed that the tableware w to be cleaned has two kinds of diameters a and b.

First, in order to align the rotary shaft 1 so as to form the inner space for the tableware wa having the diameter a with one fixing pin 25a (FIG. 8), the adjusting piece 17a (through which the fixing pin 25a penetrates) The position of the through hole 32 in FIG. 7) is adjusted by rotating the moving screw 19 within the range of the long hole 22 of the bottom plate 15 and fixed by the fixing nut 48 to set.

Next, the fixing pin 25a is pulled up from the through hole 32 set as described above against the urging force of the spring 27 and removed (FIG. 7). In this case, the lower end surface of the fixing pin 25a is slidable with the upper surface of the strip-shaped horizontal plate 30 of the adjusting piece 17 within the range of the long hole 22.

In this way, in order to align the rotary shaft 1 so as to form the internal space for the tableware wb having the diameter b with the other fixing pin 25b while pulling up the one fixing pin 25a (FIG. 8). The position of the through hole 32 of the adjustment piece 17b through which the fixing pin 25b penetrates is adjusted by rotating the moving screw 19 within the range of the long hole 22 of the bottom plate 15, and fixed by the fixing nut 48. And set.

By thus setting the two through holes 32 in correspondence with the two types of tableware wa and wb, when it is desired to match the stacked tableware wa supplied to the internal space, the two holes 32 are set for the tableware wb. When the slide block 16 is slid directly or through the fixed pin with the fixed pin 25b being lifted, the fixed pin 25a set for the tableware wa fits into the through hole 32 and the slide block 16 is locked at the same time. The rotary shaft 1 whose lower end is engaged with the slide block 16 is bent at an appropriate angle at the joint 2. Similarly, the other rotary shaft 1 is also bent at an appropriate angle at the joint 2 portion, and thus the three rotary shafts 1 set an internal space for accommodating the stacked tableware wa.

Next, when it is desired to set for accommodating the stacked tableware wb in the internal space, the slide block 16 is slid directly or through the fixed pin while the fixing pin 25a set for the tableware wa is lifted. And the fixed pin 25b set for the tableware wb is fitted into the through hole 32 and the slide block 16 is locked. At the same time, the lower end of the slide block 16 is engaged with the rotary shaft 1 with a joint 2 part. An inner space for accommodating the stacked tableware wb is set in the same manner as described above, such as being bent at an angle.

As described above, in the above-described embodiment, since the moving device 3 is configured by providing the fixing pin 25, the long hole 22, the adjusting piece 17 and the like in series, the stacked tableware w having two kinds of diameters can be operated in a single touch. An easily accommodating internal space can be formed between the three rotary shafts 1, and two types of tableware corresponding to the diameter of any tableware can be selected within the range of the long hole 22.

In the above embodiment, the fixing pin 25, the long hole 22, the adjusting piece 17 and the like are two (one pair), but they may be one kind (series), three kinds (three) or more. There is also.

Further, the moving device described above is not limited to the above structure, and it is conceivable to move the slide block by rotating the screw shaft. That is, in FIG. 10, the screw shaft S is rotatably attached to the slide block 16 in the horizontal direction. The screw shaft S is passed through the holding bracket b, and the bracket b is fixed to the bottom plate 15.

With such a structure, the slide block 16 can be moved by rotating the screw shaft S. This movement may be performed by rotating the screw shaft S manually or automatically.
