Description

[Detailed Description of the Invention] This invention relates to a device for opening the lid of a school lunch box used in school lunch centers, separating the lid and the body, and transporting each separately.

Traditionally, school lunch centers have provided anywhere from several thousand to nearly 10,000 bento meals a day to schools, factories, and other places. Many people are working hard to process the boxes so that they can be used again.

However, the food left in the collected bento boxes may rot depending on the season and emit a foul odor, so the task of opening the lid and knocking out leftover food from the box is highly discouraged.

Therefore, this idea aims to mechanize these operations by separating the bento box into the lid and the body at a speed faster than manual labor, transporting each part independently, and performing subsequent processing. It is hoped that this will be carried out smoothly.

This invention will be explained below with reference to drawings as examples.
This devising device 4 is installed in a leftover food processing device as shown in Fig. 1.For example, in a bento box provided at a school lunch center, a bento box containing rice as the main food and a bento box containing side foods are combined. In some cases, supplementary foods are placed in the main food bento box by providing a partition, but in both cases, when the bento box 2 is collected and returned, the lid part 2a is inserted into the body part 2b.
covered by.

Therefore, a feeding belt 6 which also serves as a stand for arranging the bento boxes 2 is used.
When the worker places the body on the body, it is delivered to the body transfer conveyor 7, and on both sides of this transfer conveyor 7, lid removal frames 8, 8 are arranged in fixed positions without moving, and there are carved marks on the inside surfaces of each body. Both side ends of the lid part which is crowned on the upper edge of the body part 2b of the lunch box 2 are fitted into the provided guide grooves 9, 9, and the rotating brush 10 for feeding provided between the lid removal frames 8, 8 is inserted. It is pressed against the upper surface of the lid part 2a, and is pushed out in the same direction as the body transport conveyor 7 by the frictional force of the brush.

The guide grooves 9, 9 of the lid removing frame 8.8 are disposed on the front edge, and as the lid part 2a is guided, the body part 2b is successively separated from the body part transfer conveyor 7, as shown in FIG. As shown in , the body part 2b often separates due to its own weight.

However, the body part 2b may adhere to the lid part 2a with food or other substances as an intermediary, and be guided by the lid removal frames 8, 8 and transported together.

In that case, below the guide grooves 9, 9 in the lid removal frame 8.8, a rotation roller 12 for body removal is arranged in a direction transverse to the direction of movement of the body part 2b, and collides with the front side of the body part 2b. The transfer is prevented, and the frictional force of the rotating roller 12 sends it downward and causes it to fall onto the transfer conveyor 7.

Therefore, the lunch box 2 is separated into a lid part 2a and a body part 2b.

A lid transfer conveyor 11 is disposed opposite to the intertwined ends of the lid removal frames 8, 8, and the lids 2a pushed out by the action of the rotating brush 10 are placed one after another and transferred to the washing device 3.

The meat part 2b is also sent to the next step, the scrap removal part 5, by the meat part transfer conveyor 7, and after being further processed, it is sent to the washing device 3.

From the above, according to this invention, when the bento box 2 is delivered to the body transfer conveyor 7 with the lid attached, the lid part is removed from the lid removal frame 8,
8, and is guided by the guide grooves 9, 9 on the inner surface of the lid removing frame 8.
. Body part 2b when attached and transferred
When the body part 2b does not come off, make sure to collide with the rotating roller 12,
The body part 2b can be dropped onto the body part transfer conveyor 7 instantaneously, effortlessly, and reliably.

Therefore, workers can simply arrange the bento boxes in a designated area without opening the lids, and there is no longer any bad odor that occurs in the past. The lid and body can be quickly separated, and each can be transported to a designated location by an independent conveyor, making it possible to mechanically and efficiently remove the leftover food that is stored inside the lunch box and returned to the bento box. It has become.

Claims (1)

[Scope of utility model registration request] On both sides of the body transport conveyor, which transports bento boxes with lids,
A lid removal frame is provided on the inside surface with guide grooves into which the left and right ends of the lid, which is placed over the upper edge of the body of the lunch box, are fitted in place, and the lid is inserted along the guide grooves. A rotary roller is installed at a predetermined position between the guide groove and the body transfer conveyor, and is separated above the body transfer conveyor and guided to the lid transfer conveyor, and the roller adheres to the cover and moves. The lunch box for school lunches is characterized in that the body parts are connected to each other, and the body parts are fed downward with the connecting surface downward, and the body parts are separated from the lid part and placed on a conveyor for transporting the body parts. A device that separates and transfers each part independently.
