て破損してしまう場合があつた。(Problem to be solved by the invention) At this time, the shelf boards 12-1 to 12-1 are arranged so as to eliminate the space inside the industrial furnace, for example, the roller hearth kiln 11.
The products 13-1 to 13-3 above 2-3 are transported through the roller hearth kiln 11 with almost no gaps between them, so the three rows of products are transported straight in the same direction. When the products were removed from the roller hearth kiln 11, the products sometimes came into contact with each other and were damaged.

てしまう欠点もあつた。 Also, at the furnace exit, the next process (e.g. inspection process)
In order to move the product, it was necessary to separate it from the following product group, and there were cases where it was necessary to rapidly advance the conveyance roller. In this case, if the products were drawn out in a fast forward motion only in the straight direction as in the past, there was also the drawback that products that were already close to touching each other at the furnace exit would come into contact with each other.

いる。(Embodiment) FIG. 1 is a plan view showing an embodiment of the roller hearth kiln kiln unloading device of the present invention. In this embodiment, three transport roller rows 3-1, 3-2, 3-3 are provided on the exit side 2 of the roller hearth kiln 1,
Among these, each of the rollers in the conveyance roller rows 3-1 and 3-3 is tilted at a predetermined angle α, for example, 5 to 20 degrees, in the opposite direction to the direction perpendicular to the product conveyance direction, and the central conveyance roller row 3-1 Each roller is arranged perpendicular to the product conveyance direction. Therefore, the products 5-1, 5-2, and 5-3 on the shelf boards 4-1, 4-2, and 4-3 that have been transported inside the roller hearth kiln 1 and have been baked are transported to the exit side 2 of the roller hearth kiln 1. When reaching , each product 5-1, 5-
2 and 5-3 are conveyor roller rows 3-1, 3-2, and 3-, respectively, along with shelf boards 4-1, 4-2, and 4-3.
3, it is taken out in the directions of arrows A, B, and C. That is, since the products on the conveyance roller rows 3-1 and 3-3 on both sides are conveyed in the outward A direction and the C direction, respectively, it is possible to avoid contact between the products at the time of unloading from the kiln. In addition, in this example,
The configuration is such that the angles of the conveyance roller rows 3-1 and 3-3 can be freely changed by a drive device (not shown).

にすることができる。 FIG. 2 is a front view showing another embodiment of the roller hearth kiln unloading device of the present invention. In this embodiment, the same members as those in the embodiment shown in FIG. 1 are denoted by the same reference numerals, and their explanations will be omitted. This embodiment differs from the embodiment shown in FIG. 1 in that the angles of the rollers in the conveying roller rows 3-1 and 3-3 on both sides are made different for each roller. That is, each roller of the conveyance roller row 3-1 is connected to a part of the circular radial line centered on the external point _R1 , and each roller of the conveyance roller row 3-2 is connected to the external point _R2.
It is configured so that it becomes part of a circular ray centered at . According to such a configuration, the outward movement of the product can be made smoother than in the embodiment shown in FIG.

ーにも角度をもたすことも可能である。 The present invention is not limited to the embodiments described above, but can be modified and changed in many ways. For example, in the above-mentioned embodiment, a roller hearth kiln with three product rows has been described, but it goes without saying that even if the number of product rows is increased, contact between products can be prevented by applying the present invention. In that case, by increasing the angle closer to the outer conveyor roller row, the product can be suitably discharged from the kiln. In addition, in the above-described embodiment, the central conveyance roller was configured to convey straightly, but if the conveyance direction is to be deflected, for example, each central roller may also have an angle as necessary. .

In this case, if the conveyance roller row is configured by an endless mechanism in which free rollers are attached diagonally to a chain, the endless mechanism can be kept stationary during normal product take-out and driven when the product is being rapidly transported.

Because of this, it is possible to avoid contact between products, and as a result, it is possible to reduce the risk of scratches and damage.
