Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention prevents an impact due to a drop when an article that is continuously produced or an article stored in a small container is dropped and stored in a large container. The present invention relates to an article storage device that can prevent an item from being scratched or cracked.

In addition, the article refers to tablets, capsules, etc. against impact,
A material that is easily scratched, chipped, cracked, or worn.

[Conventional technology]

Conventionally, when storing an article in a container, the article is dropped into the container from above.

Further, there is known an article drop impact mitigation device which has a spiral chute and always keeps the free fall height of the article to a minimum (see Japanese Patent Publication No. 1-21688).

[Problems to be Solved by the Invention]

In the conventional storage method of dropping from the upper part, there is a problem that the article is broken or cracked.

Further, in the article drop impact mitigation device described in the prior art, the speed of the article is suppressed by a spiral chute, further, since the free fall height is always kept to a minimum, It is said that the incidence of cracking will decrease.

However, since the sliding distance of the spiral chute is long, there is a problem that the article is worn. In addition, there is a problem that the free fall height of the article is not constant because the distance from the article surface is not always kept constant.

The present invention has been made in view of such problems of the conventional technique, and an object of the present invention is to supply an article to a hopper without using a spiral chute so that the hopper itself is an article. It is intended to provide a dropping storage device for articles that are lowered and discharged to a minimum position where they are not damaged.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides a hopper having an inlet to be supplied from a chute at an oblique upper portion and a discharge hole at a lower end, and a cylindrical hopper suspension having the lower end attached to the upper end of the hopper. Lower part, chain connected to the upper end of the hopper suspension to suspend the hopper suspension, power cylinder and piston for raising and lowering the chain, air cylinder attached to the inside of the hopper suspension. And a piston, a fixed rod connected to the lower end of the piston of the air cylinder,
A distance sensor attached to the lower end of the fixing rod and a cone lid attached to the lower part of the fixing rod to open and close the discharge hole. When the amount is supplied, by the operation of the piston of the power cylinder, the hopper suspension attached to the tip of the chain and the hopper descend in the large container, and the distance sensor is connected to the bottom of the large container or the article. It stops at a height where it detects distance and does not damage even if it drops and ejects articles, then lowers the fixing rod and cone lid by the operation of the air cylinder and piston, thereby opening the ejection hole of the hopper. It allows items to be dropped into large containers. The hopper suspension device is characterized in that it can be expanded and contracted.

Further, the chain is hung on a pair of chain wheels arranged at the upper end of the bucket box, and then wrapped around a chain wheel attached to the piston of the power cylinder like a pulley. Can be hooked inside the bucket box.

Further, it is possible to cover substantially the entire outer circumference of the hopper suspension with bellows, attach the upper end of the bellows to the lower surface of the bucket box, and attach the lower end to the lower part of the hopper suspension.

Further, the fixing rod can be connected to the piston of the air cylinder so as to be expandable and contractible.

[Action]

When a certain amount of articles are supplied from the receiving port into the hopper by the chute, the power cylinder and the piston are actuated, and the piston moves from the position shown by the solid line in FIG. 1 to the position shown by the virtual line.

As a result, the hopper suspending tool and the hopper suspended at the tip of the chain descend in the large container as shown by the phantom line in FIG. 1 due to their weight.

Then, the distance sensor detects the distance to the bottom of the large container and then to the article, and stops the operation of the power cylinder and the piston at a height where the article is not damaged even if it is discharged.

At the same time, the operation of the air cylinder and piston lowers the fixing rod and cone lid as shown by the phantom line in FIG. 1, thereby opening the discharge hole of the hopper and dropping the article into a large container. To be crowded.

When the work of discharging the articles is finished, the piston of the air cylinder raises the fixing rod and the cone lid to the original position, and at the same time, the power cylinder and the piston operate to pull the chain, so that the piston is suspended from the chain. Lift the existing hopper suspension and hopper to their original position as shown by the solid line in FIG.

Since the fixing rod is connected to the piston of the air cylinder so as to be able to extend and contract, the height position of the distance sensor is adjusted to adjust the height at which the article is dropped and discharged.

〔The invention's effect〕

Since the present invention is configured as described above, it has the following effects.

When dropping products that are continuously produced or stored in small containers into large containers and store them, the drop height is measured so that the drop rate of the hopper is measured with a distance sensor and the products are not damaged even if they are dropped and discharged. Therefore, the impact due to falling is prevented and the article is scratched, chipped, cracked,
It is possible to prevent abrasion.

Furthermore, it is possible to always provide high quality products.

Further, since the hopper suspending device is made expandable and contractible, it is possible to shorten the ascending / descending distance by the chain, that is, the expansion / contraction length of the piston of the power cylinder, which allows the power cylinder to be further downsized.

Also, when the chain is hung on the chain wheel attached to the piston of the power cylinder like a pulley after being hung on the pair of chain wheels arranged at the upper end of the bucket box, by the principle of the pulley, The end portion of the chain can be expanded and contracted twice as long as the expansion and contraction of the piston of the power cylinder, which makes it possible to further reduce the size of the power cylinder.

In addition, when the bellows covers almost the entire circumference of the hopper suspending device, the lubricating oil of the hopper suspending device is prevented from falling, and dust adhering to the surface of the hopper suspending device is large. It can be prevented from falling into the container.

Further, when the fixing rod is connected to the piston of the air cylinder in a telescopic manner, the height position of the distance sensor can be adjusted, and the height at which the article is dropped and discharged can also be adjusted. .
