Description

[Detailed explanation of the idea] The present invention relates to a flask transfer device.

Generally, the flasks in a casting line are placed on a mold truck on a rail or on a pallet on a roller conveyor, and are pushed by a piston rod of a cylinder, so that the flasks are intermittently transferred one frame at a time. Moreover, the flasks are transported in a group of many flasks. Therefore, when trying to increase the moving speed of the flask in order to speed up molding, the cylinder has to have a large diameter, and a large amount of pressure fluid is required to operate it. There were problems such as the pneumatic pressure generator being large and expensive.

The present invention has been made to solve the above problems, and one embodiment of the present invention will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a rail for transporting the mold cart 2 that constitutes the pouring line, and is inclined at a downward slope of approximately 1.5/1000 with respect to the traveling direction (rightward direction) of the mold cart 2.
And it is laid on the frame 3a. Reference numeral 4 denotes a separating device for separating the mold cart 2 on the rail 1 from the mold cart 2 on a special elevating table 11, which will be described later, and is attached to the frame 3a.
The separating device 4 includes an arm 5 that is vertically rotatably supported on the upper part of the frame 3a, and a piston rod that is pivotally supported on the upper part of the frame 3a and the tip of the piston rod is connected to the lower end of the arm 5 with a pin. It consists of a cylinder 6. Reference numeral 7 designates a cushion cylinder that brakes and receives two groups of mold carts moving on the rail 1 and a special lifting table 11 (to be described later), and is installed facing the rail 1 and at a required distance from it, and via a frame 8a. has been done. Reference numeral 9 denotes a rail for transporting the mold carriage 2 constituting a cooling line, which is located directly below the rail 1 and laid on the frame 3b.
The rail 9 is inclined to the left in the opposite direction to the rail 1 at a downward slope of about 1.5/1000.
Reference numeral 10 denotes a cylinder for pushing out a mold carriage 2 on a special lifting table 11, which will be described later, onto the rail 9, and is located opposite to the rail 9, at a required distance therefrom, and directly below the cushion cylinder 7. It is installed on the frame 8b. Reference numeral 11 denotes a special elevating table that transports the mold carts 2 downward from rail 1 to rail 9 one by one.
It is disposed between b and 8b so as to be movable up and down via an upward cylinder 12. The special elevating table 11 includes a table main body 13 and a table main body 13.
a tilting frame 14 tiltably mounted on the top;
A rail 15 fixed on the tilting frame 14
It consists of and. In addition, the tilting frame 14
The left end portion is supported on the table body 13 via a support pin mechanism 16 so as to be movable up and down, and the right end portion is supported by a support rod 17 erected on the table body 13 in a rightward downward sloping manner. Further, the rail 15 has the same width as the rails 1 and 9, and faces the rails 1 and 9 when rising and falling, respectively. Reference numeral 18 denotes an uplifting bar that pushes up the right end of the tilting frame 14 when it is lowered, and is located directly below the right side of the special lifting table 11 and is erected on the foundation. 14 to about 1.5/to the rail 9 direction.
It is designed to be sloped at a downward slope of 1000.
19 is a casting flask mounted on mold truck 2; 20
is a weight.

Next, the operation of the device configured as described above will be explained. The mold cart 2 carrying the mold flask 19 with a built-in mold flask is placed in a dumpling shape on the rails 1 and 9, and the right end cart 2 on the rail 1 is prevented from moving by the arm 5, and the cylinder 12 is extended. The special lifting table 11 is raised by the operation, and the rail 15 is made to face the rail 1.

Next, after the cushion cylinder 7 is extended, the cylinder 6 is shortened and the arm 5 is tilted clockwise, and the mold cart 2, which is shaped like a dumpling on the rail 1, is moved to the right by an extrusion cylinder (not shown). move it to This operation causes the mold cart 2 on the right end to move to the special lifting table 1.
1 and is braked by the cushion cylinder 7 to stop. In this case, rail 1,
Since the mold carriages 15 are inclined downward with respect to the traveling direction of the mold carriages 2, a large number of mold carriages 2, 2 can be moved with less force than in the case of conventional horizontally laid rails. Then,
The push-out cylinder (not shown) is shortened, and the cylinder 6 of the separating device 4 is extended, so that the arm 5
is rotated counterclockwise to move the mold carts 2, 2 on the rail 1 a slight distance in the direction opposite to the arrow and separate them from the mold cart 2 on the special lifting table 11. Subsequently, the special elevating table 11 is lowered by the shortening operation of the cylinder 12, and the rail 15 is lowered.
is made to face the rail 9, and the tilting frame 14 is tilted in the opposite direction by the projecting rod 18. Next, the extrusion cylinder 10 is extended and the rail 1
The mold truck 2 on the rail 9 is sent out onto the rail 9, and the mold truck 2 on the rail 9 is moved to the left. After the movement of the mold truck 2 is completed, the extrusion cylinder 10 is shortened and returned to its original position.

In the above embodiment, the flask 19 is transported by the mold truck 2, but it may also be transported by a pallet placed on a roller conveyor. Further, the tilting frame 14 of the special lifting table 11 is tilted by the projection of the lifting rod 18, but an upward cylinder is provided in place of the support rod 17, and the tilting frame 14 is tilted by the extension of this cylinder. Good too.

As is clear from the above description, the present invention provides two flask conveyance lines in upper and lower stages, in which the flasks travel in opposite directions and slope downward in the direction of travel. Since the ends of both lines were connected by a special lifting table equipped with a tilting frame, the cylinders that push the large number of flasks on the conveying line in a group need only have small diameter cylinders with lower output than conventional ones. Therefore, the pressure fluid generating device for operating the cylinder can be small and inexpensive, providing excellent practical effects.
