Description

[Detailed Description of the Invention] The disclosed technology belongs to a technology for preventing products from being caught in the discharge gate of a shake-out machine that transports cast products while removing sand.

This invention relates to a vibrating device that is installed on a base so that it can freely vibrate, has a cast product transfer path formed above the sieve, and is equipped with a gate at the discharge port. This vibrating device includes an intermediate gate that moves up and down behind the exit gate, and a partition plate that is extendable and retractable below the intermediate gate to block the casting product transfer path.

Generally, a production line for cast products is equipped with a vibrating device for removing sand from the product after molding.

The structure of this vibrating device is such that the main body installed on the base can be vibrated freely by a drive device, and the upper side of the sieve mounted horizontally inside the main body is used as a passage for transporting the cast products. When the cast products supplied on the road move forward due to vibration, core sand and the like are dropped onto the lower side of the sieve body.

After removing sand from the product, a gate is provided at the discharge section of the vibrating device in order to move the product to a weir folding process or the like.

However, in the past, only one gate was installed at the rear of the machine for discharging the product, so when the gate was closed, the gate often caught the cast product, resulting in damage to the gate and deterioration of product quality. there were.

The purpose of this invention is to provide an excellent vibrating device that eliminates the above drawbacks and prevents products from being caught by the gate by providing an intermediate gate behind the discharge section gate in view of the problems of conventional vibrating devices. It is something.

The structure of this invention, which is in line with the above objectives, is that when the cast product moves on the sieve by vibration, the sand is removed by vibration, and when the product is discharged from the rear, the flow of the product is stopped by the intermediate gate and the discharge part gate is opened and closed. By doing so, the product is prevented from being caught by the gate, and when the product is partitioned by the intermediate generator, the partition at the bottom of the gate comes into loose contact with the product to prevent the product from being caught. It is.

Next, an embodiment of this invention will be briefly explained with reference to the drawings.

Figure 1 shows the vibration device (shakeout machine) of this invention.
FIG. 2 is a sectional view taken along line A-A.

A main body 1 of the vibrating device is supported by a spring support mechanism 3 on a base 2, and is given constant vibration by a drive device (not shown).

The inside of the main body 1 is divided into upper and lower parts by a sieve 4 such as a perforated plate, and a product transfer path 5 is formed above the sieve 4.

? The product transfer path 5 is formed in the main body 1 in the longitudinal direction, and its base end is a product input port 6 and its tip is a product discharge lower, and a gate 8 is attached to the product discharge lower so as to be openable and closable. It is being

A frame 9 is installed at the upper rear position of the main body 1 than the gate 8, and an intermediate gate 10 is installed inside the frame 9.
is installed so that it can be raised and lowered via rollers 11.

A chain 12 is connected to the upper end of the intermediate gate 10 and is hung on a plunger wheel 16 of a cylinder mechanism 15 on the side of the frame 9 via two wheels 13 and 14 on the frame 9.

A large number of forks 17 are attached to the lower side of the intermediate gate 10 as partitions.

This fork 17 has a flange 18 formed at its base end, and a straight portion is loosely inserted into the lower part of the intermediate gate 10.
A flange 718 is in contact with the intermediate gate 10 and is suspended under its own weight.

In addition, the frame 9 that suspends the intermediate gate 10 is configured so that its installation position on the main body 1 can be adjusted, and furthermore, a frame 9 is provided in front of the discharge lower of the main body 1 in order to transfer the product to the next step. A trolley packet 19 is movably equipped.

In the above configuration, the cast product molded into a predetermined shape in the previous step is transferred from the input port 6 of the main body 1 to the product transfer path 5 on the sieve body 4.
The cast product is sequentially supplied into the interior, and is transported in the direction of the arrow by the vibration of the main body 1 by the drive device, and along the way, green sand,
Core sand and the like are separated, and the sand passes through the sieve 4 and falls to the bottom of the main body 1, where it is sent to a sand treatment process.

To discharge the cast product from the discharge lower, first, with the gate 8 closed, the plunger wheel 16 of the cylinder mechanism 15 is extended, the intermediate gate 10 is lowered, and the product transfer path 5 is blocked by the fork 17. .

At this time, a part of the cast product is sandwiched between the lower end of the fork 17 and the upper surface of the sieve body 4, but when the fork 17 hits the product, it protrudes into the intermediate gate 10 as shown by the chain line in FIG. As a result, the product is pinched by the weight of the fork 17.

Therefore, the fork 17 and the cast product will not be damaged.

Next, with the intermediate gate 10 closed, the gate 8 is opened, and the cast product existing between the gate 8 and the intermediate gate 10 is discharged into the trolley packet 19 and transferred to the next stage of work.

Then, the gate 8 is closed with no product present between the gate 8 and the intermediate gate 10, and the intermediate gate 10 is raised and opened to allow the cast product to advance between the intermediate gate 10 and the gate 8.

By repeating this operation, the cast products can be sequentially poured.

Note that the aspect of this invention is not limited to the above-described embodiment; for example, the fork 17 may be attached to the intermediate gate 9 via a spring so that the fork 17 can expand and contract downward with a certain elastic force. Also good.

As mentioned above, according to this invention, since the intermediate gate is arranged behind the discharge gate of the vibration device main body, the discharge gate can be closed without any cast product existing between the discharge gate and the intermediate gate. This has the effect of preventing improper loading due to products popping out or accidents in which products are caught in the discharge gate and damaging the gate or products, thereby maintaining product accuracy.

In addition, since the product discharged from the discharge port of the main body is a constant amount that exists between the discharge port gate and the intermediate gate, the amount of product cut out per gate opening and closing is constant, and the product is transferred to the next stage process. Conveyance efficiency is improved.

Furthermore, since the partition below the intermediate gate is attached so as to be expandable and retractable, the product will not be damaged when the intermediate gate is closed.
