Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is applicable to the case where a heat treatment such as solution treatment or quenching of metals such as steel or stainless steel is carried out by charging an object to be heated into a furnace or heating it. The present invention relates to a device for taking in and out of a heated object that can take out the heated object from the furnace and quickly cool it.

<Conventional technology> Conventional method for moving in and out of this type of heated object! ! As shown in Fig. 6, A station (1) is a trolley mounted on a trolley (3) that runs on rails (2) arranged along the direction in which heated materials (M) enter and exit the batch furnace (F). Equipped with a drive motor (4) and a trolley (3)
One end of a wire lobe (7) hung from a tower-shaped pedestal (5) installed above via a pulley (6) is attached to a lift (on which a heated object (M) is placed horizontally protruding from the tip of the cart (3). 8), the other end of the wire lobe (7) is connected to a balance weight (9), and a chain wheel (not shown) is attached to the middle of a rotating shaft having pulleys (6) at both ends. ) and a chain wheel (10a) connected to a lift drive motor (10) with a chain (7a) to raise and lower the lift (8).

A case will be described in which a heat object (M) heated in a batch furnace (F) using such a conventional heat object loading/unloading device (1) is rapidly cooled using water or oil.

First, the entire heated object inlet/output device (1) is moved by a trolley drive motor (
4) brings it closer to the batch furnace (F). Next, the lift drive motor (10) is driven to move the entire loading/unloading device (1) backward while the object to be heated in the furnace is still lifted using the lift (8). Then, the inlet/outlet device (1) is retreated until the lift (8) with the object to be heated comes to a position above the water tank or oil tank (T), and then the inlet/outlet device (1)
) is stopped, the lift (8) is lowered, and the object to be heated is placed in a water tank or an oil tank for rapid cooling. After cooling treatment,
A series of operations were carried out, such as lifting the lift (8) from the tank and transferring the cooled object to the next conveyance means.

<Problems to be Solved by the Invention> However, in the above-mentioned conventional device for taking in and out of heated materials, the entire device (1) is moved forward as close as possible to the batch furnace (F), and the lift (8) is used to move the entire device (1) forward. The heated object heated in the furnace (
A series of operations such as lifting the device (M), moving the entire device backwards in that state, stopping it above the water tank or oil tank, and lowering the lift (8) to immerse the heated object (M) in the water tank or oil tank. In order to carry out the quenching process through the process, it is difficult to take out the object to be heated from the furnace and quickly quench it. In addition, the above-mentioned conventional heated material loading/unloading device can only be installed for one batch furnace (F), so it can be installed separately for multiple batch furnaces. This method has the disadvantage that a dedicated access device must be installed, and that it requires a large installation space.

Moreover, the conventional device for loading and unloading heated objects only travels back and forth between the furnace and the water tank or oil tank, and the heated objects are transported up to the list (8) before being put into the furnace, or the heated objects are transported to list (8) after being cooled. Completely different equipment had to be used to transport the product to the next process.

The present invention has been made in order to eliminate the above-mentioned conventional drawbacks, and its purpose is to make it possible to take out the heated object from the furnace and quickly quench it, and to make it possible to quickly cool it down in a plurality of batch furnaces. An object of the present invention is to generally provide a device for loading and unloading a heated object, which allows the loading and unloading of a heated object using only one loading and unloading device, and also eliminates the need to transport the heated object before and after heat treatment. .

Next, the arm is rotated, the transfer cart connected to the arm is run on the cart, and the transfer cart is moved to the top of the cart. Then, the rotating holder is rotated, and the engaging member at the tip thereof is engaged with the engaging protrusion of the tray. While in this engaged state, when the arm is rotated to return to its previous position, the transfer trolley and the tray carrying the heated object move backward, and the tray is lifted onto the elevator at the elevator mounting position on the trolley. move it to the top.

Next, the carriage is driven to the front of the batch furnace, with the rotating holder of the transfer carriage still being engaged with the tray, and the carriage is stopped there. Next, when the arm is rotated, the tip of the transfer cart hits the V2 end of the tray. On the other hand, although the engagement between the rotating holder and the tray is somewhat looser due to the gap between the tip of the transfer cart and the rear end of the tray, the two are still in an engaged relationship and the tray is Its movement is regulated by a rotating holder so that it does not move forward independently.

Then, the 1-ray is moved forward along the top of the carriage by the transfer carriage, and the 1-ray carrying the object to be heated is stored in the batch furnace. Next, the rotating support is rotated to release the engagement with the tray, and the transfer carriage and arm are returned to their original positions.

The material to be heated in the batch furnace is heated at a predetermined temperature for a predetermined period of time by rotating an arm on a cart placed in front of the furnace (12) and moving the transfer cart forward along the cart. Move the cart to the top of the cart.

Then, the rotating holder is rotated so that the engaging member at the tip thereof engages with the engaging protrusion of the tray. While in this engaged state, when the arm is rotated to return to its previous position, the transfer trolley and the tray carrying the heated object move back, and the tray is located at the elevator mounting position on the trolley. Move to the top of the lift. The rotating holder of the transfer cart remains engaged with the tray. Next, the cart is driven to the top of the water tank or oil tank and stopped there. With the tray placed on the lift of an elevator, the lift is lowered, the lift and tray are immersed in a water tank or an oil tank, and the object to be heated is immersed in the water tank or oil tank for a predetermined period of time. When the lift moves down F, the rotating holder of the transfer cart is not engaged with the lowering of the lift, so the lift is released from the rotating holder. After soaking for a predetermined period of time, the lift is raised and the tray is lifted to a position on the trolley.

The cart is then moved to move on to the next process.
