The front stopper 44 is moved down in front of a shooter 5 to roll the formed article 1' into the receiving part 52 of the shooter. Such operation is repeated. According to this constitution, manual work is eliminated and all work is mechanized.

Description

[Detailed Description of the Invention] The present invention enables round bars such as carbon electrode rods, which are difficult to handle manually, to be stacked in bales, to be taken out in alignment while breaking the bale stacking condition, and to be transferred to a conveyance line for the next process. The present invention relates to the provision of an unloading device useful for sending out.

Conventionally, carbonaceous round bar-shaped compacts stacked in bales are aligned and taken out by hand, using something like a lever to break the stacked condition of the cutting-edge products on the supply side. The molded books were rolled and sent to the conveyance line.

For this reason, the following problems arise.

(a) Large carbonaceous molded bodies cost 1,500 yen per piece.
Kg, and what's more, the temperature is high immediately after taking it out of the furnace.

For this reason, manually handling these scraps is not only labor intensive but also dangerous.

(b) Breeze powder (carbon powder) that adheres to the compact during furnace treatment is undesirable from the viewpoint of labor when it is blown up during work such as breaking down stacked bales.

(c) It is impossible for one person to work with a dog-sized bar, and it becomes two tasks, which is not efficient.

The purpose of the present invention is to eliminate the need for manual work and to perform all mechanical work when such difficult-to-handle round bars are fed in bales one by one to the conveyance line for the next process. The object of the present invention is to provide an extremely useful aligning and unloading device that enables the alignment and unloading.

That is, the apparatus of the present invention includes a transfer path provided to extend from a supply section for stacked round bars to a point in front of the conveyance line, and a shooter that receives the round bars taken out in front of the transfer path and sends them out to the conveyance line. and a pair of stoppers that are movable along the transfer path and are provided so as to be freely raised and lowered in the front and rear directions of the movement direction, and the pair of stoppers are provided with:
When the front stopper receives the tip of the round bar stock, the rear stopper stops! After the bar is raised to pick up and take out one round bar forward and move to the front end of the transfer path, the front stopper is lowered so that the bar can be transferred to the shooter. It is characterized by

Hereinafter, an example in which a carbonaceous molded body is used as a round bar material will be explained with reference to the drawings.

Graphitization of carbonaceous compacts is carried out by placing the compacts in a furnace and heating them. In this case, heating in the furnace is done in a batch manner, so once the compacts are taken out of the furnace, they are heated in an appropriate manner. After being docked, to the conveyance line for the next process 1
The books are arranged and sent out one by one. Stock is stacked in bales due to space constraints.

According to this button of the invention, an alignment and take-out device 4 and a chute are installed between the slat conveyor 2 that stores carbonaceous molded bodies 1, 1, 1, etc. in bales and the feed conveyor 3 that serves as a conveyance line to the next process. 5 and placed respectively.

The alignment and take-out device 4 and the chute 5 are respectively disposed on a track truck Z which is provided so as to be able to run freely on tracks 6 and 6 laid along the feed conveyor 3. It travels between a plurality of slat conveyors, and sequentially takes out the formed bodies 1', 1.1, etc. stacked in bales by placing them on any slat conveyor 2 and sends them to the feed conveyor B. .

A slat conveyor 2 is arranged on a cart Z.
A transfer rail 41.41 that forms a transfer path is attached to extend toward the feed conveyor 3 from a position along the molded body mounting surface, and a rail 41.41 is also provided on the trolley 7.
A transfer trolley 43 connected to a hydraulic cylinder 42 so as to be movable along the
It is equipped with a front stopper 44 and a rear stopper 45 which are provided so as to be able to move up and down via a hydraulic cylinder so that they can move up and down with respect to the rails 41 and 41, respectively (front and back in the extending direction), Front stopper 4
4 is equipped with a detector 44a, which detects the arrival of the bale-stacked compacts 1, 1.degree. 1, . . . supplied from the conveyor 2.

When the front stopper 44 detects the arrival of the molded bodies 1, 1.1, etc., the rear stopper 45 is raised, and the front stopper 44 moves toward the rails 41, 4.
When moving forward toward the tip side of f, it is lowered. Further, when the cart 43 moves backward toward the slat conveyor 2, the front stopper 44 is raised and the rear stopper 45 is lowered.

Furthermore, a rear stopper 45 is provided via a hydraulic cylinder so as to be movable back and forth with respect to the carriage 43 so that the distance between the front and rear of each stopper can be adjusted in accordance with the size of the outer diameter of the molded body.

On the other hand, the chute 5 is rotatably connected to a hydraulic cylinder 51 and arranged on the trolley 7 between the tip of the rail 41, 41 and the feed conveyor 3.
When the part 52 rotates toward the rails 41 and 41, the molded body receiver extends along the tip of the rail 41 and 41, and when the part 52 rotates in the opposite direction, it extends to the side of the molded body traveling position of the feed conveyor B. There is.

According to such a device, first, the track truck 7 is moved to a position next to an arbitrary slat conveyor 2, and then the bale-stacked compacts 1, 1, . If the arrival of the tip molded body 1' of '1...' is detected by the detector 44a of the front stopper 44,
A rear stopper 45, which has been set in advance to move in accordance with the outer diameter of the molded body with respect to the stopper 44, is moved back and forth by a hydraulic cylinder or the like, and is raised at the set position.
