A filing cabinet with a mechanism for preventing the box body from tilting and falling over

Abstract

The present invention relates to the field of object storage, and specifically to a filing cabinet with a mechanism for preventing a box body from tilting and falling over, which is intended to optimize the automatic storage and retrieval process of a filing box and prevent the filing box from tilting and falling over. The filing cabinet includes a placeholder, which is composed of a mounting seat and an elastic V-shaped bar. The elastic V-shaped bar is connected to the mounting seat through a horizontal rotating shaft, and the mounting seat is provided with horizontal and vertical limit grooves to control the state conversion of the elastic V-shaped bar. When the filing box is stored normally, the elastic V-shaped bar maintains a horizontal storage state; when the AGV takes away the filing box, the elastic V-shaped bar can be rotated to a vertical state through the clamping part to support the adjacent filing box to prevent the adjacent filing box from tilting and falling over. When the filing box is returned, the elastic V-shaped bar is reset to a horizontal state. In addition, the placeholder is equipped with a ball and a slope surface design to reduce friction, ensuring easy and efficient operation and stable and reliable operation.

Description

Technical Field

[0001] The invention relates to the field of object storage, and in particular to a filing cabinet with a mechanism for preventing a box body from tilting and falling over. Background Art

[0002] With the continuous development of technology, AGV (Automated Guided Vehicle) unmanned automatic archives are becoming more and more popular. The loading and unloading of file boxes in this type of archive is automatically performed by AGV, which has the functions of automatically locating, finding and grabbing file boxes.

[0003] However, in actual applications, paper documents in file boxes are generally not evenly packed, and paper documents are also flexible. When placed vertically for a long time, they will bend due to gravity and be in an eccentric state. They need effective support from the adjacent file boxes to stay vertical, otherwise they are likely to tilt and fall. When the AGV takes one file box from a row of already arranged files, the adjacent file box may tilt and fall due to eccentricity. When the AGV returns to return the file box, it needs to straighten the tilted file box before putting the original file box back. To implement this function, on the one hand, it increases the layout cost of the AGV, and on the other hand, it also reduces work efficiency.

[0004] Therefore, there is a need for a filing cabinet that is more suitable for unattended filing rooms, which can support the file boxes next to it when the AGV takes away the file boxes, and facilitate storage when the file boxes are returned without interfering with the normal storage of the file boxes. Summary of the invention

[0005] The technical problem to be solved by the present invention is how to prevent an eccentric file box from falling over in an unattended file room.

[0006] The specific technical solution of the present invention to solve the above technical problems is:

[0007] A filing cabinet with a mechanism to prevent a box body from tilting and falling over comprises a bottom plate and a top plate, wherein the bottom plate is used to place the box body, and the top plate and the bottom plate together form a storage space for the filing box; the cabinet also comprises a placeholder, which is foldably arranged on the lower surface of the top plate, and comprises a mounting seat and an elastic V-shaped strip, wherein the mounting seat is provided with a mounting hole, a horizontal limit groove and a vertical limit groove, horizontal rotating shafts are respectively arranged at both ends of the elastic V-shaped strip, and limit ribs are arranged at the ends of the horizontal rotating shaft, and the limit ribs are adapted to the horizontal limit groove and the vertical limit groove, and a clamping portion for AGV operation is also arranged on the horizontal rotating shaft, and the elastic V-shaped strip is rotatably arranged on the mounting seat via the horizontal rotating shaft.

[0008] Compared with the prior art, this solution has the following beneficial effects:

[0009] This solution provides a mutual supporting structure that prevents the file box from tilting and falling over.

[0010] When the file box is stored normally, the placeholder is in a storage state and does not hinder the storage of the file box, that is, the elastic V-shaped bar is in a horizontal state, and its limiting rib is located in the horizontal limiting groove. When the AGV takes away a file box, the AGV passes through the clamping part of the clamping placeholder, and the elastic V-shaped bar is deformed by the extrusion force, and the V shape becomes narrower, thereby causing the limiting rib to leave the horizontal limiting groove, but the horizontal shaft is still in the installation hole and will not fall out. Since the clamping part mainly bears the opposite holding force, the friction in the circumferential direction around the shaft is The friction force is small, so after the elastic V-shaped bar is freed from the constraint of the limit groove, it will rotate around the mounting hole to a vertical state under the action of its own gravity. After the AGV releases the clamping part, the elastic V-shaped bar restores its original opening degree under the action of its own elasticity, and the limit rib is stuck in the vertical limit groove. At this time, the elastic V-shaped bar occupies the position of the removed file box, and the inclined side edges of the elastic V-shaped bar are supported on the adjacent file box to achieve mutual support, ensuring that the adjacent file box will not tilt and fall over, which is convenient for the operation of returning the file box.

[0011] When returning the file box, first use the AGV to clamp the clamping part so that the limiting rib is disengaged from the vertical limiting groove, and then put the file box back. The file box generates thrust on the elastic V-shaped bar, causing it to rotate around the mounting hole, and then return from the vertical state to the horizontal state and enter the storage position.

[0012] Furthermore, a plurality of balls are provided on the clamped surface of the clamping portion, which further reduces the friction of the clamping portion when the AGV is clamped, so that the elastic V-shaped strip can be more easily rotated from a horizontal position to a vertical position under the action of gravity.

[0013] Furthermore, the balls are evenly arranged around the horizontal rotating shaft, which ensures that the friction force around the circumference of the mounting hole on the clamping part is very small during the whole process of switching between the vertical position and the horizontal position.

[0014] Furthermore, a smoothly transitioned slope surface is provided between the horizontal limit groove and the vertical limit groove, and the end of the limit rib is adapted to the slope surface. With this structure, when returning the file box, as long as the elastic V-shaped strip deviates from a very small angle, the end of the limit rib is matched with the slope surface, and the AGV can release the clamping part. Under the elastic force of the elastic V-shaped strip itself, it will exert downward pressure on the slope surface, and the slope surface will generate an upward rotation component force on the elastic V-shaped strip, so that it returns to a horizontal state under the action of its own elastic force until the limit rib is stuck in the horizontal limit groove.

[0015] Furthermore, the mounting seat is adsorbed on the top plate by strong magnetism.

[0016] Furthermore, a cavity is provided in the mounting seat, a strong magnet is provided in the cavity, an operating switch is fixedly connected to the strong magnet, and the operating switch is used to control the switching of the strong magnet between the first end and the second end of the cavity. A magnetic conductor is provided at a position corresponding to the first end of the cavity. When the strong magnet is located at the first end, the strong magnetism extends to the surface of the mounting seat through the magnetic conductor, thereby realizing the magnetic adsorption of the mounting seat. When the strong magnet is located at the second end, because there is no magnetic conductor to guide the magnetism, the magnetism is not enough to be transmitted out, and the magnetism displayed to the outside is weak, thereby realizing the demagnetization and removal of the mounting seat. In this way, there is no need to set a placeholder at the corresponding position of each file box, and the number of places to be placed in each storage compartment can be determined according to statistics.

[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] like Figure 1 As shown, when one of the file boxes 4 in the filing cabinet is taken away, the file box 4 next to it may fall down due to lack of support, and when the AGV returns to the original file box 4 again, it will be hindered.

[0029] like Figure 2 As shown, a filing cabinet with a mechanism to prevent the box body from tilting and falling includes a filing cabinet body 1, wherein the filing cabinet body 1 includes a bottom plate 2 and a top plate 3, wherein the bottom plate 2 is used to place a filing box 4, and the top plate 3 and the bottom plate 2 together form a storage space for the filing box 4; in a multi-layer filing cabinet, the bottom plate 2 of the upper layer is also the top plate 3 of the next layer; and further includes a placeholder 5, wherein the placeholder 5 is arranged on the lower surface of the top plate 3, and only one placeholder 5 is schematically drawn in the figure. Figure 3 As shown, the placeholder 5 includes a mounting seat 7 and an elastic V-shaped strip 6; Figure 4 As shown, the mounting seat 7 is provided with a mounting hole 8, a horizontal limit slot 9 and a vertical limit slot 10; Figure 5 As shown, horizontal rotating shafts 11 are respectively provided at both ends of the elastic V-shaped bar 6, and limiting ribs 12 are provided at the ends of the horizontal rotating shaft 11. The limiting ribs 12 are adapted to the horizontal limiting grooves 9 and the vertical limiting grooves 10. The horizontal rotating shaft 11 is also provided with a clamping portion 13 for AGV operation. The elastic V-shaped bar 6 is rotatably arranged on the mounting seat 7 via the horizontal rotating shaft 11.

[0030] Furthermore, a plurality of balls 14 are provided on the clamped surface of the clamping portion 13 .

[0031] Furthermore, the balls 14 are evenly arranged around the horizontal rotation shaft 11 .

[0032] Furthermore, if Figure 4 As shown, a smoothly transitioned slope surface 15 is further provided between the horizontal limiting groove 9 and the vertical limiting groove 10 , and the end of the limiting rib 12 is adapted to the slope surface 15 .

[0033] When the file box 4 is stored normally, the placeholder 5 is in a horizontal storage state, that is, the elastic V-shaped strip 6 is in a horizontal state, and its limiting rib 12 is located in the horizontal limiting groove 9 (such as Figure 6 As shown in the figure, when the AGV takes away a file box 4, the AGV passes through the clamping portion 13 of the clamping placeholder 5, and the elastic V-shaped strip 6 is compressed and deformed inward by the extrusion force, and the V-shape becomes narrower, so that the limiting rib 12 leaves the horizontal limiting groove 9, but the horizontal shaft 11 still does not fall out of the mounting hole 8. Since the clamping portion 13 mainly bears the opposite clamping force, and a plurality of balls 14 are provided on the surface of the clamping portion 13, the circumferential friction force is small. Therefore, after the elastic V-shaped strip 6 is freed from the constraint of the limiting groove, it rotates around the mounting hole 8 to a vertical state under the action of its own gravity (as shown in the figure). Figure 8As shown), after the AGV releases the clamping portion 13, the limiting rib 12 is inserted into the vertical limiting groove 10, and the elastic V-shaped bar 6 is in a vertical state, occupying the position of the removed file box 4, and resting on the file box 4 next to it, ensuring that the file box 4 next to it will not fall over, which is convenient for the operation of returning the file box 4.

[0034] When returning the file box 4, the AGV is used to clamp the clamping portion 13 to disengage the limiting rib 12 from the vertical limiting groove 10, and then the file box 4 is put back. The file box 4 generates a thrust on the elastic V-shaped strip 6 to rotate around the mounting hole 8. Once the limiting rib 12 passes over the side wall of the vertical limiting groove 10, the clamping portion 13 can be released, and the elastic V-shaped strip 6 expands outward under its own elastic force, and the limiting rib 12 abuts against the slope surface 15 (such as Figure 7 As shown in the figure, the slope surface 15 gradually transitions from a vertical state to a horizontal state. Therefore, during the expansion of the elastic V-shaped strip 6 due to its own elastic force, the horizontal shaft 11 moves axially, pushing the limiting rib 12 to move axially. The limiting rib 12 is constrained by the slope surface 15, and the horizontal shaft 11 synchronously rotates axially until the elastic V-shaped strip 6 returns from a vertical state to a horizontal state and enters the storage position. Therefore, when returning the file box 4, it is not necessary to completely push the elastic V-shaped strip 6 to a horizontal position by the file box 4. It only needs to be pushed over the side wall of the vertical limiting groove 10 so that the limiting rib 12 abuts against the slope surface 15 to release the clamping portion 13.

[0035] Furthermore, the mounting seat 7 is strongly magnetically adsorbed on the top plate 3. Specifically, a cavity is provided in the mounting seat 7, a strong magnet is provided in the cavity, an operating switch is fixedly connected to the strong magnet, and the operating switch is used to control the switching of the strong magnet between the first end and the second end of the cavity. A magnetic conductor is provided at a position corresponding to the first end of the cavity. When the strong magnet is located at the first end, the strong magnetism extends to the surface of the mounting seat 7 through the magnetic conductor, thereby achieving magnetic adsorption of the mounting seat 7. When the strong magnet is located at the second end, because there is no magnetic conductor to guide the magnetism, the magnetism is not enough to be transmitted out, and the magnetism displayed to the outside is weak, thereby achieving demagnetization and removal of the mounting seat. In this way, there is no need to set a placeholder 5 at the corresponding position of each file box 4, and the number of places to be placed in each storage compartment can be determined based on statistics.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
