BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading conveyor used for feeding a raw material in which sheet-like substances such as pulp are piled up in bulk into a pulper or for transporting and distributing other articles. It is about.

[0002]

2. Description of the Related Art Conventionally, in order to convey a sheet-like substance such as pulp unpacked in a papermaking facility or flat articles in a piled state, an endless belt using a belt or a member similar thereto is used. Conveyors are often used, but the pulper that feeds and puts in pulp has a high height and a large difference in height, and after lifting it to a predetermined height, the conveyor has a predetermined angle and forms a slanted load carrying surface. It is known to lift or load.

[0003]

However, in the conventional inclined conveyor, when the articles are piled up in bulk, the relative positions and postures of the articles are often collapsed due to vibration during transfer, and the articles fall off horizontally or slightly. If only a conveyor that has been used is used, and if a load collapse or an attitude control mechanism is attached in order to prevent these, it will be structurally complicated and expensive, and there will be a drawback that the operability will decrease and there is a limit to the angle at which the conveyor can be inclined. , It requires a large installation area. Moreover, in the case of a large pulper, because it is bulky, conveyors for feeding pulp, except for the lift type, can be loaded at the pulper input port through a number of stages with a gentle inclination angle In some cases, the pulp collectively falls and there is a problem that the operating time and operating load at the pulper will increase, and if the pulper itself is installed on a low floor and the height is adjusted, it will be expensive in terms of equipment. There were problems such as troublesome maintenance and security. In the present invention, it is intended to appropriately eliminate these conventional drawbacks, and even if the bulk goods are conveyed at a steep angle with a conveyor having an endless load carrying surface, the bulk goods can be stably transported without the load collapse. An object of the present invention is to provide a loading conveyor that is capable of being dropped and divided at the time of loading articles to facilitate post-processing and reduce the installation area to make the apparatus compact.

[0004]

SUMMARY OF THE INVENTION The present invention comprises a slat conveyor having a steeply angled transition surface as a load carrying surface, and a fork is provided on the slat conveyor so that the fork can be raised and lowered. A cam roller is provided via an arm, a guide with which the cam roller is brought into contact is provided on the slat conveyor inversion side, and the upper portion of the slat conveyor is supported by a frame.

[0005]

[Operation] When the unpacked sheet-like pulp is conveyed horizontally in a piled state, the articles are lifted by a fork that rotates from the lower side of the slat conveyor that moves endlessly at the lower reversal side. While being transported to the steeply inclined transition surface of the load carrying surface, it is sequentially carried upward, and the cam roller abuts on the guide on the upper reversal side of the slat conveyor. Next, the pulp lifted with a fork is divided into slices when dropped and spontaneously falls to enable efficient operation of the pulper, which reduces the loading load and enables smooth operation, and also the conveyor inversion. At the rear of the fork, the fork is laid down, folded down, and returned.Then, the fork is erected to reach the lower reversal side, and new goods can be continuously picked up and carried, and even if there is a height, it can carry a steep angle. It is guaranteed that goods will be transported in a smooth and safe state, the equipment area can be greatly reduced, and it can be used effectively, which will contribute to downsizing of equipment.
