Description

Push-to-open container

This creation system relates to a device for automatic feeding, especially a feeding device for feeding powdery items.

In the existing fully automated production line for preparing dyestuffs, a weighing device is used to add a certain amount of masterbatch powder to a weighing cup, and then a robotic arm is used to pick up the weighing cup and move it to the top of the dye bath. , and then use the robotic arm to pour the color masterbatch powder in the weighing cup into the dyeing liquid tank to prepare the dyeing agent. That is to say, in addition to the three axial degrees of freedom of movement, the existing robotic arm needs to have at least one rotational degree of freedom in order to perform the action of pouring the powder cup on the weighing cup.

However, the more degrees of freedom of the robotic arm, the more complex its structure will be, which will adversely affect equipment cost, reliability, and maintainability.

Therefore, the weighing cup of the prior art needs to be improved.

In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a press-to-open container, which only needs to press down the top of the container with an external object such as a mechanical arm to open the bottom of the container and free the contents of the container. When it falls, it can be operated with a simple mechanical arm.

In order to achieve the above-mentioned creation purpose, the technical means used in this creation is to design a press-down open container to hold a content, and the press-down open container includes: a base, the bottom of which is formed with a first discharge port. ; a main body, which can be moved up and down through the base; the main body is formed with an accommodating space for containing the content; an upper opening and a second outlet, which communicate with the accommodating space and are respectively located in the accommodating space Opposite to the main body; the second discharge port is located above the first discharge port; an opening and closing mechanism is set at the second discharge port of the main body and linked to the base; when the main body is opposite When the base moves up to a closed position, the opening and closing mechanism closes the second outlet of the main body; when the main body moves down relative to the base, the opening and closing mechanism unblocks the second outlet of the main body , so that the content in the main body leaves the press-opening container through the second outlet and the first outlet.

Specifically, the reset elastic member 33 is a compression spring, which surrounds the guide tube 11 , and the two ends of the reset elastic member 33 abut against the base 10 and the linkage portion 322 of the displacement rotating member 32 respectively, whereby the reset elastic member 33. The displacement rotating member 32 tends to move upward and pushes against the main body 20 through the shutter 31, so that the main body 20 tends to move upward relative to the base 10 to the closed position. To put it simply, when the main body 20 is pressed down by no external force, the reset elastic member 33 tends to move the main body 20 upward, and the opening and closing mechanism 30 normally closes the second discharge port 203 .

In other preferred embodiments, the reset elastic member 33 is not limited by the compression spring, and the two ends of the reset elastic member 33 are not limited to contact the base 10 and the displacement rotating member 32, only the reset elastic member 33 can make the main body The 20 tends to move upward relative to the base 10 to the closed position.

The specific structure of the opening and closing mechanism 30 is not limited to the above, as long as the second discharge port 203 can be closed or unclosed according to the up and down movement of the main body 20. For example, the opening and closing mechanism 30 can also be an existing flip seal (ie. Usually, the printing surface is pressed up on the printing pad, and when the user presses down, the printing surface will move down and leave the printing pad and turn the stamp printed on the downward side), which is used to move the printing surface down from the printing pad and turn it over.

When the present invention is used as a weighing cup of a fully automated dyeing agent production line, the quantitative masterbatch powder (that is, the content C) is first placed in the main body 20 (as shown in FIG. 5 ), and then a robotic arm (not shown in the figure) shown) pick up the present invention and move it to the top of the dye bath (not shown in the figure), and then the robotic arm only needs to Move down, and continue to move down an appropriate distance after the base 10 abuts against the opening periphery of the dye liquor tank, so that the main body 20 is pressed down by the mechanical arm to drive the opening and closing mechanism 30 to unclose the second outlet of the main body 20 203 (as shown in FIG. 6 and FIG. 8 ), so that the content C in the main body 20 automatically slides down into the dye bath below, and the action of releasing the content C is completed.

To sum up, in the present invention, by disposing the opening and closing mechanism 30 between the base 10 and the main body 20 , the contents of the present invention can be released through a simple and conventional pressing action, which is more convenient to use. Specifically, when the present invention is applied to an automated production line, the robotic arm of the production line must have the degree of freedom to move up and down in order to grip and move the container. In the present invention, the existing up and down movement degrees of freedom of the robotic arm can be used to perform the action of releasing the contents, so that the robotic arm does not need to add a rotational degree of freedom for releasing the contents, so that the automated production line can be equipped with a machine with a simpler structure. The arm can save the overall cost of the automated production line and improve the reliability and maintainability of the automated production line.
