Description

[Detailed Description of the Invention] The present invention relates to a cleaning device that automatically cleans a large number of lunch boxes of the same type with leftover food and side foods while continuously transporting them.

The reality is that supplementary foods and leftover food left in lunch boxes used for school lunches are traditionally washed by the recipient, and this work requires a lot of manpower, time, and considerable expense. There is.

The aim of this project is to automatically wash empty lunch boxes with washing water during continuous conveyance, to remove leftover food, and to wash the empty lunch boxes in a short period of time with a small amount of manual labor. There is.

To explain the present invention with reference to an embodiment shown in the drawings, a conveyor 1 for transporting lunch boxes is suspended between rotating wheels 2 and 3 and is arranged to transport lunch boxes intermittently by means of an interlocking rod 5 associated with a crank 4. ing.

At a predetermined position in the front of the rotary wheel 3, a grid-shaped guiding aid 9 with a base 8 attached is installed on the upper end support shaft 7 of the operating lever 6, and behind a transmission rod 10 connected to the lower end of the operating lever 6. The end is connected to a rotating cam 12 via an L-shaped lever 13 supported on a support shaft 11, and the actuation of the cam 12 causes the operating lever 6 to rotate back and forth about the support shaft 7. As a result, the guiding aid 9 is moved while the conveyor is being transported.
A fountain nozzle 15 is placed close to the front side of the rotating wheel 3 so as to be raised away from the front side of the rotating wheel when the conveyor 1 stops, and at the same time is installed behind the guiding aid 9.
The bento box is then washed by spraying cleaning water onto the bento box, which has been transported by a conveyor and stopped in front of the rotating wheel.
At this time, the residue of the secondary food is washed down and transferred without being obstructed by the guide aid 9, and the washed lunch box approaches the rotating wheel 3 at the same time as the conveyor starts moving. After moving a certain distance while being held by a guiding aid, the device falls onto a conveyor below and is transported.

In this way, the cleaning work automatically cleans the lunch boxes sent on the conveyor one by one.

In the drawing, reference numeral 16 is an adsorption device for separating the lid of the lunch box.

Since this device is configured as described above, when a bento box with a lid is placed at a predetermined position on the transfer conveyor by hand, the placed lunch box will automatically have its lid removed by the suction device 16 during the transfer. The lid is then transferred as is to a predetermined location on the lid transfer conveyor, while the lunch box with the lid removed is intermittently transferred on conveyor 1 and rotated as shown by the chain line in Figure 2. When the conveyor stops at the same time as the conveyor is conveyed to the front position of the wheel 3, the guiding aid 9 located at the position shown by the solid line in FIG. The cleaning water jetted from the cleaning water injection nozzle 15 cleans and removes leftover food and side foods attached to the inside of the lunch box.

When the cleaning is finished, the conveyor starts moving again, and the guiding aid 9 returns to the front side of the rotary wheel to support the cleaned lunch boxes and transport them as the conveyor moves. When the bento box reaches the predetermined position, it naturally separates from the holding of the guide aid 9, falls onto the conveyor below, and is carried to the predetermined position.

As described above, the lunch boxes that are intermittently conveyed to the front side position of the rotary wheel 3 by the conveyor 1 are automatically cleaned.

In this way, according to the present invention, cleaning is performed automatically without requiring the labor of many people as in the past, so cleaning does not require a lot of expense and time as in the past, and Since it can be cleaned efficiently, it is suitable for cleaning lunch boxes for school lunches and other large quantities of lunch boxes that use the same type of lunch boxes, and has great practical benefits in terms of saving cleaning costs.
