The demand for camping-related products is rapidly increasing due to the revitalization of the current camping culture.

In general, wood used for intestinal function is cut to a certain size after logging, and may be packaged in a certain amount for storage, transport, or sale, but it is difficult to pack a large amount of wood in a uniform amount due to the nature of the bulky and heavy wood. There is a problem, and accordingly, a small amount of packaging method by manpower is mainly used.

However, there is bound to be a limit to the amount of packaging only with a small amount of packaging method by manpower, and there are cases where the packaging operation is difficult depending on the shape and size of the wood to be packaged. However, these requirements are not fully satisfied.

The wood cut for firewood use is cut to a certain size through a cutter, but due to the irregular shape of the wood, it is difficult for the cut woodwork wood to be cut to the exact same shape and length. There was no choice but to manually sort and pack firewood of size and length, resulting in reduced work efficiency and reduced productivity.

On the other hand, in the prior art, a 'wood packing device for intestinal function (Korean Patent Registration No. 10-2022858)' for simply and quickly packaging a large amount of wood having various shapes and sizes in a uniform amount and used for intestinal function has been proposed. .

However, in this conventional long-acting wood packaging device, the rotary packaging unit rotates in a state in which the wood is loaded inside the main body portion and is configured to wind the packaging material on the lower side of the main body portion, and at the same time, the main body portion is periodically fixed by the lifting unit As the distance rises, the packaging material wound on the lower side is configured to pack the wood exposed to the outside, and it is a device for packing a large amount of wood for firewood, and it is not suitable for packing a small amount of firewood for retail sale.

In other words, workers are inevitably involved in the overall process of selecting and supplying the size of the cut wood, and firewood packaging equipment for a small amount of sold products sold as individuals who are packaged in relatively small quantities has not been developed. There is a need for system development.

At this time, two vertical plates 222 of the hopper 22 are vertically erected on the first conveyor 21, and the two vertical plates 222 constitute one set and a plurality of set hoppers at regular intervals. (22) may be installed consecutively. That is, the operation of stopping after the first conveyor 21 moves by a certain distance, for example, by the interval of the hopper 22 corresponding to one set is repeated.

In this way, after the operator loads the cut firewood in the inner space of the hopper 22, the first conveyor 21 moves horizontally and is transported toward the set position.

Here, the amount of firewood loaded in at least one or more hoppers 22 may be an amount to be contained in one packaging box (B).

On the other hand, in the quantitative loading unit 20, when an operator loads firewood into the hopper 22, a protruding reference line 24 is provided on one side of the first conveyor 21 to visually check the firewood having a protruding length. can be formed.

That is, the firewood loaded into the hopper 22 is uniformly loaded only with firewood having the same length, and in the case of the longer firewood, it undergoes a sorting operation. The protruding firewood can be easily checked with the naked eye and selected. For example, if it is confirmed that a specific firewood crosses the protruding reference line 24 in the process of loading a plurality of firewood into the hopper 22 by the operator, the firewood can be determined as firewood having a length exceeding the reference length. have.

In this way, the length of firewood that is different from the standard value is firewood with a protruding length, which interferes with loading into the packing box (B) in the rear packing process, as well as reduces the value of the product, so the same length as the standard value It is desirable to sort the external firewood before loading it into the packing box (B).
