Abstract

PROBLEM TO BE SOLVED: To reduce an installation space and increase the cooling speed by providing a conveying device comprising a lifting tower for lifting many plate materials at spaces in the horizontal attitude, a lowering tower for lowering the plate-like material, and a bridge for transferring the plate-like material from the lifting tower to the lowering tower. SOLUTION: A high-temperature plate-like material (b) is carried to a placing position A to a frame (d) having a traveling wheel and a guide wheel by a conveyer. A plate-like material (b) placed on the frame (d) is hooked on an angle material 3 stretched between chain conveyers 2 driven by a motor 1 provided on a lifting tower B and lifted intermittently. On reaching the top, the material is travelled on a bridge C by a hook 5 fitted to a chain 4 to reach the top of the lowering tower D. The plate-like material (b) is hooked on the angle material 3 stretched between the chain belts 2 and intermittently lowered, the plate-like material (b) is lifted from a frame (d) at the lowemaost position to be sent to a carry-out position E, and the frame (d) is returned to the placing position A.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for drying, for example, a plate having one surface coated, or conveying the plate heated for drying to cool it.

[0002]

2. Description of the Related Art Conventionally, in order to heat a plate-like object coated on one surface for drying and then cool it to a stackable temperature, a roller conveyor is extended from an outlet of a dryer,
It radiated heat while traveling on it.

[0003]

For this reason, there is a problem that a long roller conveyor has to be laid and a large space is required.

Means for Solving the Problems, Actions and Effects As a means for solving such problems, the invention according to claim 1 includes a rising tower for raising a large number of plate-like objects in a horizontal posture at intervals. , The plate-like object is lowered at the same speed as the ascending tower, and the bridge at the upper end of both towers is configured to transfer the plate-like object from the ascending tower to the descending tower. It takes a long time to ascend at intervals, and then it takes a long time to descend, during which cooling is performed, and the transport path is a gate shape consisting of an ascending tower, a descending tower, and a bridge connecting both towers. Therefore, there is an effect that it can be installed in a narrow space. The cooling speed can be increased by sending cool air between the rising and falling plate-like objects.

According to a second aspect of the present invention, in the first aspect of the present invention, a frame on which plate-like objects are placed one by one, and a lower portion between both towers and a lower portion of the descending tower are always retracted below the frame. A roller that supports the plate-like object so that it can run by ascending through the frame is provided, and the plate-like object is placed on the frame at the lower part between both towers, and at the lower part of the descending tower Since the sheet is taken down from the frame, a flexible plate-like object can be reliably conveyed.

According to a third aspect of the present invention, in the second aspect of the present invention, since the traveling wheel is provided on the frame, the traveling of the frame can be performed smoothly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

First, the outline of the operation will be described with reference to FIGS. 1, 2 and 3. FIG. 1 is a plan view showing the outline of the present embodiment, and FIG. The conveyed high-temperature plate-like material b is conveyed by a conveyor c to a mounting position A on a frame d provided with a traveling wheel e and a guide wheel f shown in FIG. 3, and is mounted on the frame d. The plate-shaped object b is the rising tower B
The hook 5 attached to a chain 4 which is intermittently lifted by being caught by an angle member 3 passed over a chain conveyor 2 driven by a motor 1 and driven by a motor 1 and circulating horizontally when reaching the top. Bridge C
Drive up and reach the top of the descending tower D, and the ascending tower B
And is intermittently lowered by being hooked on the angle material 3 passed over the chain conveyor 2 driven in the opposite direction by the motor 6, and at the lowest position thereof, the plate-like material b
Is lifted from the frame d and sent to the unloading position E, and the frame d is returned to the mounting position A.

While the ascending tower B is ascending and the descending tower D is descending, a plate-like object b
During this time, cool air is blown in to promote cooling.

Next, the details of the operation will be described with reference to FIG. 4 and the following figures. As shown in FIG. 4, when the plate-like material b carried out of the drying furnace a is carried into the mounting position A, FIG. As shown in FIG. 5, the roller 9 projects upward through the space between the frames d placed on the chain conveyor 8 driven by the motor 7 by extension of the piston rod 11 of the air cylinder 10. As shown in FIG. 6, the roller 9 descends due to the contraction of the piston rod 11 of the air cylinder 10, and the plate-like material b is placed on the frame d on the chain conveyor 8, as shown in FIG. Tower B which is placed and run by the chain conveyor 8
7 and is caught by the angle member 3 due to intermittent running of the chain conveyors 2 on both sides and ascends in the ascent tower B as shown in FIG.

A frame d on which a plate-like object b reaching the uppermost position of the ascent tower B is placed, as shown in FIGS. 8 and 9, is hooked on a hook 5 attached to a chain 4 to form a bridge C. It is moved to the rails 12 constituting it, travels on it, is mounted on the descending tower D, and descends intermittently.

The traveling rolling wheels e and the guide rolling wheels f of the frame d move when traveling from the rising tower B to the descending tower D through the rails 12 and when being transferred from the mounting position A to the rising tower B. Make the running smooth.

As shown in FIG. 5, when the frame d on which the plate-shaped object b is placed reaches the lowermost stage of the descending tower D and is placed on the stationary chain conveyor 13, the piston rod 17 of the air cylinder 16 A roller 14 including a roller that is driven to rotate by a motor 15 by extension extends upward from between the frames d to receive the plate-shaped object b, and the roller 14
6, the roller 14 is retracted below the chain conveyor 13 due to the contraction of the piston rod 17 of the air cylinder 16, and the frame d is moved by the movement of the chain conveyor 13, as shown in FIG. One cycle is completed by returning to the mounting position. By repeating this cycle, many plate-like objects b are cooled.
