Description

[Detailed Description of the Invention] The present invention is capable of aligning and unloading round bars, such as carbon electrode rods, which are difficult to handle by hand, while breaking the stacked state of the bales, and transferring them to the conveyance line to the next process. The present invention relates to the provision of an unloading device that is useful when sending out to.

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

For this reason, the following problems arise.

(a) Large carbonaceous molded bodies weigh 1500 kg each.
Moreover, it is hot immediately after being taken out of the oven. Therefore, processing this manually is laborious and dangerous.

(b) Breeze powder (carbon powder) that adheres to the molded bodies during furnace treatment is unfavorable in terms of occupational health as it flies up during work such as breaking down bales.

(c) It is impossible for one person to work with large-sized bars, and two
The work efficiency is not good because it requires manual labor.

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 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, a shooter that receives the round bars taken out in front of the transfer path and sends them out to the conveyance line, and It is equipped with 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 back of the movement direction, and the front stopper of the pair of stoppers receives the tip of the round bar stacked in bales. When this happens, the rear stopper is raised to pick up and take out one round bar to the front, and after moving to the front end of the transfer path, the front stopper is lowered and the round bar can be transferred to the shooter. It is characterized by doing something like this.

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 batches, so the compacts taken out from the furnace are Once they are properly stocked, they are aligned and sent out one by one to a conveyance line for the next process. Stocks are stacked in bales due to space constraints.

According to this invention, the carbonaceous molded bodies 1, 1, 1...
An alignment and take-out device 4 and a shooter 5 are respectively arranged between the slat conveyor 2 that stores bales of... and the feed conveyor 3 that serves as a conveyance line to the next process.

Therefore, the alignment and take-out device 4 and the shooter 5 are connected to tracks 6, 6 laid along the feed conveyor 3.
The slat conveyors 7 are respectively disposed on track carts 7 which are provided so as to be freely travelable, and the slat conveyors 2 are placed on any slat conveyor 2 and stacked in bales. The molded bodies 1, 1, 1, .

The alignment and take-out device 4 has transfer rails 41, 41 which form a transfer path attached to the cart 7 so as to extend from a position along the molded object mounting surface of the slat conveyor 2 toward the feed conveyor 3. A transfer trolley 43 connected to a hydraulic cylinder 42 so as to be movable along rails 41, 41 on the trolley 7
The rails 41, 41 are arranged at the front and rear of this truck 43 (front and rear in the direction in which the rails 41, 41 extend), respectively.
In contrast, 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, and the front stopper 44 is equipped with a detector 44a. , the arrival of the stacked bales 1, 1, 1, . . . supplied from the conveyor 2 is detected.

When the front stopper 44 detects the arrival of the molded bodies 1, 1, 1..., the rear stopper 45 is raised, and the front stopper 4
When the rails 4 move forward toward the tips of the rails 41, 41, they are lowered. Furthermore, trolley 43
When moving backward toward the slat conveyor 2, the front stopper 44 is raised and the rear stopper 45 is lowered. Furthermore, the rear stopper 4 is designed so that the distance between the front and rear of each stopper can be adjusted in conjunction with the size of the outer diameter of the molded body.
5 is provided via a hydraulic cylinder so that it can move back and forth with respect to the trolley 43.

On the other hand, the stopper 5 is rotatably connected to the hydraulic cylinder 51 on the trolley 7 between the tips of the rails 41, 41 and the feed conveyor 3, and When the rail 4 rotates toward the rails 41, 41 side, the rail 4
1 and 41, and by rotating in the opposite direction, it extends to the side of the molded article traveling position of the feed conveyor 3.

According to this 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, 1, . . . are supplied from the conveyor 2 to the rails 41, 41. When the detector 44a of the front stopper 44 detects the arrival of the tip molded body 1, the stopper 44
On the other hand, the rear stopper 45, whose movement is set in advance in accordance with the outer diameter of the molded body, is moved back and forth by a hydraulic cylinder or the like, and is raised at the set position. As the rear stopper 45 rises, the stopper 45 and the front stopper 44 sandwich the most advanced molded body 1' from the front and back, and while they are held in place, the molded body 1' is molded forward. It moves forward by more than the outer diameter of its body to break the bale-stacked state and at the same time pull it away from the bale-stacked state.

One molded body 1' to be separated is a stopper 4
The molded body 1' is transferred on the rails 41, 41 to the front of the shooter 5 by the forward movement of the molded body 4, 45, and then, as the front stopper 44 is lowered, the molded body 1' rolls into the shooter receiving portion 52.

The compact 1' transferred to the shooter 5 is sent to the feed conveyor 3 by the rotation of the shooter 5.

In this way, the stacked bales are taken out one by one in line and sent out one by one while breaking the stacked bale condition by the related operations of the front and rear stoppers 44, 45 and the shooter 5. When the conveyance of the molded products from the rat conveyor is completed, the cart 7 is moved to the next rat conveyor, and the above-mentioned operation is repeated to carry out alignment, take-out and delivery.

Reference numeral 31 in the figure is a stopper provided to prevent the molded product 1' sent out by the shooter 5 from jumping out excessively and to accurately place it on the conveyor 3.

In the above example apparatus, the bale-stacked product is made of carbonaceous molding, and the molded product is weak against impact, and it is necessary to break the bale-stacked state at a very slow speed.Moreover, it is heavy and requires a powerful drive. In order to do this, hydraulic pressure is especially used to control the movement and elevation of the stopper, as well as the rotation of the shooter.

However, the device of the present invention can also be applied to aligning and unloading cylindrical rods other than carbonaceous compacts, and as a driving source for the stopper and shooter, in addition to hydraulic pressure, compressed air or electric screws whose movement speed can be controlled can also be used. Available.

Furthermore, although a slat conveyor is used to supply the round bars stacked in bales, a pusher or similar device that can move the stacked bales may also be used to push them.

As explained above, according to the aligning and unloading device of the present invention, round bars that are difficult to handle manually are automatically aligned and taken out one by one without manual labor, and transferred to the next process. It has the effect of contributing to improved work efficiency, work safety, and work hygiene.
