2. Description of the Related Art Conventionally, as an automatic skewer, Japanese Patent Publication Sho 63
The one described in JP-A-55329 is known. This is configured such that an endless chain having yakitori skewers mounted at intervals between facing infrared heaters arranged parallel to each other is conveyed downward from above and baked. Since the endless chain is quadrilaterally stretched around four wheels, the vertical side of the infrared heater is vertically aligned on the upper side of the infrared heater. Before reaching the infrared heater, the yakitori skewer is preheated to a steamed state,
After that, it is the usual way to make the main porcelain. However, in this conventional one, since the endless chain is in a straight line in the steaming process, both sides and the lower surface of the meat piece stabbed on the Yakitori skewer are steamed with hot air from below. However, hot air does not easily turn on the upper surface. To supplement it, a preheating chamber of complicated structure,
Although a heat storage chamber is provided, it takes time to steam the upper surface of the meat piece, resulting in poor work efficiency. Further, the skewer mounting cylinder has a female screw at the base thereof and is mounted with a screw by a U-shaped mounting piece mounted on the chain, but it is directional and requires a lot of labor for mounting.

The yakitori skewer is attached to a vertical side opposite to the vertical side of the infrared heater side of the endless chain hung in a quadrangle, and since the vertical side is the same straight line shape as described above, the attachment is also performed. For safety, the upper and lower wheel portions on the vertical side are covered with a cover, so the number of yakitori skewers to be attached is limited, and only a few can be attached. Therefore, the worker is hung up on the skewer and the work efficiency is poor. To increase the number of skewers to be attached, the vertical side will be lengthened, but the machine itself will be a large scale.

Furthermore, at the bottom of the endless chain,
As an automatic mechanism for removing the yakitori skewer, as shown in FIG. 7, the twisting spring B, which is the operation source, causes the removal lever L to release the contraction in conjunction with the movement of the endless chain, and the tip of the lever L is removed. Although it is removed from the skewer mounting cylinder by hitting the meat piece, the movement of the lever L is a rotational movement of a radius r centered on the fulcrum S. Therefore,
Due to the size of the piece of meat, and the variation of the attachment position of the piece of meat to the Yakitori skewer, there is a lot of missing and lack of certainty.

[0005]

It is possible to attach a large number of skewers when attaching the skewers to a skewer.
In the steaming process of the foods attached to the skewers, it is possible to steam efficiently and surely. Another object is to provide an automatic skewer that can automatically and surely remove skewers.
