[0002]

2. Description of the Related Art For example, Japanese Patent Publication No. 3-57773 discloses that a tray on which tableware after eating is transported by a transport conveyor is tilted by a tray conveyor, and the tableware is dropped onto a falling waste sorting conveyor. A dishwashing pre-processing system is described in which dishware from which garbage is removed is preliminarily washed and then sent to a dishwashing device.

[0003]

However, the above-mentioned dishwashing pretreatment system has means for stacking trays after dropping dishes, but does not have a structure for washing trays. In addition, it does not mention sorting of various kinds of tableware of different sizes sent to the dishwashing apparatus, and at present it depends on humans for these operations.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a post-eating lower table cleaning system for automatically cleaning and sorting dishes and trays.

[0005]

In order to achieve the above-mentioned object, the present invention provides a post-eating lower table cleaning treatment system, comprising: a conveyor for conveying trays on which post-eating dishes are placed;
A tray overturning conveyor for overturning the tray sent from the transporting conveyor and dropping the tableware to the slag removal device, a tray cleaning device for cleaning the tray conveyed by the tray overturning conveyor, and the tray overturning conveyor It is characterized by being composed of a swarf removal device that removes leftovers from tableware that has fallen from, a tableware separation device that separates tableware from which leftovers have been removed, and a dishwasher that cleans the separated tableware. I have.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings. Shimozen cleaning system 1 installed in the cleaning room, after eating in the dining room,
A small plate made of synthetic resin placed on a tray 2 made of synthetic resin,
Tableware 3 of various sizes such as a middle plate, a large plate, a teacup, and a bowl are separated from silverware such as chopsticks, knives and forks, and the tableware 3 is washed and then sorted into respective types. System.

[0007] The lower table cleaning processing system 1 comprises a conveyor 4 for conveying a tray 2 on which dishes 3 and the like after eating are placed from a cafeteria to a washing room, and a rollover of the tray 2 sent from the conveyor 4. Tray 6 for dropping the tableware 3 and the like on the tray 2 to the separation device 5, a tray cleaning device 7 for cleaning the tray 2 conveyed by the tray roll conveyor 6, and the separation device 5 Garbage removal device 8 for removing the garbage from the several types of tableware 3 that has fallen off, tableware separation device 9 for separating the varieties of tableware 3 from which the garbage has been removed, and tableware washing device for cleaning the separated tableware 3 10
It is composed of

The separating device 5 is installed between the tray roll conveyor 6 and the slag removing device 8 to separate silverware such as chopsticks, spoons, knives and forks from tableware 3. For example, metal silvers are separated by a magnet conveyor, and chopsticks, paper waste, and the like are removed, and the synthetic resin tableware 3 and the leftovers are dropped into the leftover removal device 8. Thereby, troubles when the tableware 3 is sent from the garbage removal device 8 to the tableware separation device 9 are reduced.

The tray roll conveyor 6 is installed downstream of the transport conveyor 4 and rolls the tray 2 that has been fed in a horizontal state by 90 degrees, and transfers the tableware 3 placed on the tray 2 to the separation device 5. Let it fall. Tray rollover conveyor 6
The tray cleaning device 7 is installed in the latter half of the tray. The tray cleaning device 7 has a shower for spraying water on both sides of the tray 2 that has been set upright and horizontal by the tray roll conveyor 6 to clean the tray 2. At the end, the tray 2 stacked with the stacking means of the tray 3 is provided. A transfer means for transferring to the automatic guided vehicle 11 is provided.

The slag removal device 8 is provided with a scooping conveyor 8b and a blower pipe 8c in a water tank 8a, and is formed by water supplied from a circulating water supply port 8d and bubbles blown out from the blower pipe 8c. Tableware 3 dropped by water flow
, And the tableware 3 is completely separated from the garbage. The tableware 3 from which the leftovers have been removed is sent to the tableware sorting apparatus 9 by the frying conveyor 8b. The residual rice is sucked together with water from a suction pipe (not shown) provided at the bottom of the water tank 8a, separated from water by a separator (not shown), and the filtered water is sent to the circulating water supply port 8d.

The tableware sorting apparatus 9 includes a plurality of tableware drop holes 9a, 9b, 9 having a gradually increasing diameter from upstream to downstream.
c, 9d... are formed, and the tableware falling holes 9a, 9 are formed.
An immersion tank 12 is provided below b, 9c, 9d,.... The immersion tank 12 is provided with the tableware drop holes 9a, 9b, 9
c, 9d... immersion tanks 12a, 12b, 1 partitioned for each
2c, 12d... The tableware 3 of various sizes sent to the tableware drop holes 9a, 9b,
While passing over 9c, 9d,..., They fall from tableware drop holes 9a, 9b, 9c, 9d,. Are separated into groups of a certain size.

Each immersion tank 12a, 12b, 12c, 12d
.. Indicates that the dishwashing apparatus 1 is pre-washed for the tableware 3 divided into groups, and the dishwasher 1
Each has a gate on the discharge side to send to zero.

The dishwashing apparatus 10 has a built-in dishwasher, and after washing the dishes in a group, further separates the dishes into small dishes, medium dishes, large dishes, teacups, and the like.
Separated into the same type such as bowls, and an automatic guided vehicle 11 for each tableware
Transfer to

Therefore, the washing and sorting of the tableware 3 after eating and the cleaning of the tray 2 can be performed automatically without relying on humans, which contributes to sanitary and significant cost reduction. .

[0015]

As described above, the after-eat eating lower table cleaning treatment system of the present invention comprises a transport conveyor for transporting a tray on which dishes are eaten, and the tray sent from the transport conveyor. A tray roll conveyor that rolls over and drops the tableware to the garbage removal device, and a tray cleaning device that cleans trays conveyed by the tray roll conveyor,
Since it was composed of a garbage removal device for removing garbage from tableware dropped from the tray rollover conveyor, a ware separation device for separating ware from which garbage was removed, and a dishwasher for cleaning the separated crockery, Since washing and sorting of various dishes and eating and cleaning of trays after eating can be performed automatically without relying on humans, it is hygienic and can contribute to a significant cost reduction.
