Technical Field

The invention relates to a material storage device.

Background

Conventional storage device is mostly by the material condition in the operating personnel according to the hopper, controls the loading and unloading of material. When the storage device is arranged in a longer production line, the mode of direct operation and control by people is not easy to ensure the production efficiency, and the physical burden of operators is also larger.

In order to save space and reduce cost, the weighing sensors with small quantity and small volume are used as a better design idea. 3 or more than 3 weighing sensors are used for supporting the hopper, so that the hopper has better stability; but if one wants to further save costs on the load cell and reduce the location where the load cell is placed, using 2 load cells would be a better direction; however, when the gravity center of the hopper and the gravity center of the hopper after the material is added do not coincide with a vertical plane formed by the centers of the two symmetrically arranged weighing sensors, the relative state of the hopper and the weighing sensors becomes unstable.

Disclosure of Invention

The technical problem to be solved is as follows:

under the condition of only using two weighing sensors, the weighing results of the gravity center of the weighed hopper and the gravity center symmetrical weighing sensor after the materials are added into the hopper are not influenced; compared with the conventional storage device, the storage device is more convenient to use and easy to control and operate.

The technical scheme is as follows:

the invention aims to realize a material storage device which comprises a support, a hopper, a material suction device, a weighing sensor, a material sensor, an inserting plate and a control device.

The weighing system comprises a hopper, a bracket, two weighing sensors, a weighing sensor and a controller, wherein the two weighing sensors are symmetrically arranged, supported between the hopper and the bracket and used for weighing the hopper and the materials in the hopper; the support is provided with a vertical guide device, the hopper is provided with a guide post, the vertical guide device limits the guide post to move in the vertical direction, and the vertical guide device is used for overcoming the influence on weighing possibly caused by the fact that the gravity center of the hopper and the hopper after materials are added is not overlapped with the vertical plane formed by the centers of the two symmetrical weighing sensors.

According to the weighing completion condition of the weighing sensor and the detection condition of the material sensor on the material in the hopper, the control device automatically controls whether the suction device feeds materials or not and whether the inserting plate unloads materials or not.

In order to conveniently clean the hopper and seal the hopper, an upper cover is arranged on the hopper.

Has the advantages that:

the weighing sensors are convenient to arrange, the required number is small, and the cost can be reduced; the automation, the operation is simple and convenient, and the control is easy; the hopper is convenient to clean.

Detailed Description

In order to realize the technical solution in the summary of the invention, the following design is selected as a preferred embodiment.

Referring to fig. 2, a bracket body 1-1 of the bracket 1 is provided with a load cell support 1-2 and a vertical guide device 1-3. The weighing sensor support 1-2 and the vertical guide device 1-3 are arranged oppositely and symmetrically, and the weighing sensor support 1-2 is positioned between the upper vertical guide device 1-3 and the lower vertical guide device 1-3 in the vertical direction.

As shown in figure 3, the vertical guiding device 1-3 is provided with a roller 1-3-1 and a gap 1-3-2.

As shown in figure 4, the hopper body 2-1 of the hopper 2 is provided with an upper guide column 2-2, a lower guide column 2-3, a hopper feed inlet 2-4, an upper hopper cover 2-5, a hopper discharge outlet 2-6, a material sensor mounting port 2-7 and an inserting plate mounting port 2-8.

As shown in fig. 1, the present embodiment includes a support 1, a hopper 2, a suction device 3, a load cell 4, a material sensor 5, an insert plate 6, and a control device 7. The feed inlet 2-4 of the hopper is fixed and communicated with the suction device 3. The guide post 2-2 penetrates through a notch 1-3-2 of the vertical guide device 1-3 arranged above, and two side surfaces are in contact with the roller 1-3-1; the lower part 2-3 of the guide column penetrates through a notch 1-3-2 of the vertical guide device 1-3 arranged below, two side faces are in contact with the roller 1-3-1, and the weighing sensor 4 is supported between the upper part 2-2 of the guide column and the weighing sensor support 1-2. The material sensors 5 are respectively arranged on material sensor mounting openings 2-7 arranged at the upper end and the lower end of the hopper body 2-1. The inserting plate 6 is arranged on the inserting plate mounting opening 2-8 at the lower part of the hopper body 2-1. The control device 7 is fixed above the hopper body 2-1.

The embodiment operates as follows:

the hopper 2 has only a degree of freedom in the vertical direction under the restraining action of the rollers 1-3-1 on the vertical guides 1-3 on the guide posts 2-2 and guide post lower 2-3, respectively. When the gravity center of the hopper 2 is not coincident with the vertical plane formed by the centers of the two symmetrical weighing sensors 4 or the gravity center of the hopper 2 with the material added therein is not coincident with the vertical plane formed by the centers of the two symmetrical weighing sensors 4, the friction force can be sufficiently reduced by the rollers 1-3-1, so that the weight measured by the weighing sensors 4 is still the weight of the hopper 2 or the whole weight of the hopper 2 and the material.

The material suction device 3 is used for adding materials into the hopper 2; the material sensor 5 positioned above is used for detecting whether the hopper 2 is filled with materials or not; the material sensor 5 positioned below is used for detecting whether materials exist in the hopper 2 or not; the inserting plate 6 is controlled by an electric driving mechanism or a pneumatic mechanism and is used for controlling whether the materials flow out from the discharge port 2-6 of the hopper or not; the upper cover 2-5 can clean the hopper 2 after being opened and can seal the hopper 2 after being closed.

The control device 7 can automatically control the material suction device 3 and the inserting plate 6. For example, when the lower material sensor 5 detects that the hopper 2 has no material, the control device 7 controls the inserting plate 6 to close the hopper discharge port 2-6, and controls the material suction device 3 to add the material into the hopper 2; when the upper material sensor 5 detects that the hopper 2 is filled with materials, the control device 7 controls the material suction device 3 to stop adding the materials into the hopper 2; after the weighing sensor 4 finishes weighing the hopper 2 and the materials in the hopper, the control device 7 controls the inserting plate 6 to open the discharge port 2-6 of the hopper, and the materials are unloaded.

The present embodiment is not limited to the above-described unique usage, and other usage forms may be programmed based on the functions of the devices and components.
