Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an automatic coil annealing apparatus for continuously carrying a coil of metal strip, such as copper, into an annealing furnace and annealing the coil.

(Prior Art) This type of coil annealing apparatus normally anneals the coil by placing the coil on a tray having honeycomb-shaped holes on a conveyor and passing it through an annealing furnace. Conventionally, a crane was used to load and unload the coils onto this tray. However, with this method, the coil is suspended by the wire rope of the crane and carried from the stockyard onto the tray, and the wire rope is lowered and the moment the coil touches the tray, the crane is lowered and moved to remove the coil. The wire rope was pulled out by holding down the coil with a square bar on the tilting tray, and then the square bar was removed while lifting the coil with a lever bar, which was dangerous and required skill, and also during transportation. There is a risk of damaging the coil. In particular, when the annealed coil is lifted with a pry bar, the edges are pried, which has the disadvantage of significantly degrading the quality of the coil. Furthermore, in addition to the coil loading and unloading work, manual pushing work is required while transporting the tray, resulting in a drawback of low workability.

(Objective of the Invention) An object of the present invention is to provide an automatic coil annealing device that can efficiently and continuously anneal a coil without requiring any skill.

(Structure of the Invention) The automatic coil annealing apparatus of the present invention includes an annealing furnace having a conveyor that sequentially conveys a plurality of trays each carrying a coil to be annealed, and a conveyor that transports the coils from the outlet of the annealing furnace to the coil delivery position. a tray conveyance means for conveying the tray from the delivery position to the entrance of the annealing furnace; a coil delivery conveyance means for leaving the tray at the coil delivery position and taking out only the coil on it or passing the coil onto the tray;
Coil transfer means for transferring the coil to be delivered by the coil delivery and transport means between the coil delivery and transport means and the coil receiving means or the coil shipping means; and a coil loader for delivering the coil to the coil receiving means or the coil shipping means. It is equipped with The coil delivery and conveyance means includes a conveyance section aligned with the tray conveyance means and a lifter that moves up and down through a gap between the conveyance section and a honeycomb-shaped hole in the tray. The lifter has a raised position where it receives coils from the tray on the conveyor and passes the coil to the tray, and a lowered position where it can drive the conveyor. A coil loader consists of a transport section that is driven between a horizontal position and an inclined position, and a hook mechanism that protrudes or retreats from between the transport section. It has a hook that can move forward and backward to hold the coil.

According to this automatic coil annealing device, the coils are placed on a tray in order from the coil receiving means and passed through the annealing furnace, and after annealing, the coils are sequentially passed from the tray to the coil shipping means and the coils are efficiently and automatically annealed. can do.

Therefore, when the piston rod 62a of the hydraulic cylinder 62 is expanded or retracted, the movable frame 54 rotates within an angular range of 90 degrees. The drive roller 56 is aligned in the same direction as the drive roller 40 of the receiving table 32 at one position of the movable frame 54, and is aligned in the same direction as the roller of the tray conveying means 20 later on at another position rotated by 90 degrees from this one position. They are arranged side by side. These drive rollers 56 are driven by a motor 64 mounted on the movable frame 54 via a chain sprocket mechanism 66.
