Description

Technical Field

[0001] The present invention belongs to the technical field of document storage and access, and in particular is an assemblable document storage and access system. Background Art

[0002] With the development of society, the management of documents has become more and more refined, and the scale of documents has become larger and larger. Traditional document cabinets require manual classification and access, but it is time-consuming and laborious to find and access documents, so automatic document cabinets have emerged. Automatic document cabinets generally have problems such as inaccurate document recognition and low success rate of document storage and retrieval. Specific problems include: 1. When documents are stored in a purely automated manner, since the location is fixed, there is no identification when accessing them. The exact location can be searched for access. However, if a person does not follow the pre-set rules and directly accesses the documents from the document cabinet, inaccurate document recognition will occur.

[0003] 2. When there are a large number of documents, the documents tend to be tightly pressed together. Since the gaps between the documents are small, the automatic clamping device will fail to automatically access the documents because the access clip cannot extend into the gaps between the documents and cannot perform the clamping action.

[0004] 3. A document cabinet can only store a limited number of documents. When the total number of documents is too large, multiple automatic document storage and retrieval devices will be required. If there is no communication between the multiple automatic document storage and retrieval devices, it will be impossible to automatically access the documents, and manual assistance will still be required. If multiple automatic document storage and retrieval devices communicate with each other, each automatic document storage and retrieval device needs to be installed with a communication module, and communication anomalies are prone to occur. At the same time, the cost of installing automatic document storage and retrieval devices on a large scale is also high.

[0005] For example, the patent publication number CN109820350A discloses an automatic classification and retrieval document cabinet, which includes a base, a document rack part, a sliding rack part, a document pick-up and placement part, a document transport part and a moving part. When the invention is used, the moving part first moves the entire device to a designated position, and the position of each document folder is stored in the control computer. When it is necessary to take the document, the sliding rack part drives the document pick-up and placement part to move to the position where the document folder is placed, and the document folder is taken out and placed on the top of the document transport part, and then transported to the document pick-up box for manual removal. When it is necessary to place the document folder, the sliding rack part drives the document pick-up and placement part to move to the back of the document storage box, and the document folder is taken out and placed in the designated position. However, it provides a traditional automatic storage cabinet, which still has the above problems. Summary of the invention

The technical solutions in the examples are described clearly and completely. Example

[0027] like Figure 1 , an assemblable document storage and retrieval system, comprising: A document rack module, the document rack module includes a document rack 1, an elastic limiting device 3, a document folder 2 and an identification code, the document rack 1 is divided into an automatic storage surface and a manual storage surface, the elastic limiting device 3 is arranged on the side of the document rack 1 close to the manual storage surface; the document folder 2 includes a positioning plate 21, a side plate 22, an opening plate 23 and a closing plate 24, the positioning plate 21 is provided with a clamping groove 211, and a clamping cross bar is arranged inside the clamping groove 211, and the identification code includes a document folder identification code and an access identification code; like Figure 2 , access module, the access module includes a document access clip 4, a transmission component, a fixed cross bar 6 and a storage frame 7, the document access clip 4 includes a fixed plate 401, a positioning clip 402, a fixed clip 403 and an electric shaft 404, the transmission component includes a transmission device 501 and a transmission fixed frame 502, and the transmission fixed frame 502 is driven to move by the transmission device 501; the document access clip 4 is slidably mounted on the transmission fixed frame 502; the storage frame 7 is fixed on the transmission fixed frame 502 and is located below the document access clip 4, and the storage frame 7 is provided with a card slot for fixing the document clip 2; The control module includes a server and an identification control device 8 . The identification control device 8 includes a control device and an identification code camera. The identification control device 8 is fixedly mounted on the fixing plate 401 .

[0028] like Figure 6 , the elastic limiting device 3 comprises: Spring base 301; The fan-shaped abutting device 302 has a through hole at the center thereof and a limiting protrusion 303 at the arc-shaped outer edge; A cylindrical rotating shaft 304, which passes through the through hole and is fixedly connected to the document holder 1, so that the fan-shaped abutting device 302 can rotate around its axis; The fan-shaped resisting device 302 is arranged on the top of the spring base 301, and the arc surface of its fan-shaped structure faces away from the placement position of the document folder 2, and a limiting protrusion 303 is provided at the end of the fan-shaped surface; the limiting protrusion 303 is a block structure extending along the fan-shaped surface. When the document folder 2 is pushed in so that the limiting protrusion 303 is perpendicular to the installation plane of the document rack 1, the limiting protrusion 303 forms a rigid stop surface to resist the document folder 2.

[0029] The limiting protrusion 303 can be manually pressed below the installation plane of the document rack 1 so that documents can be manually accessed from the manual storage surface.

[0030] like Figure 4The side plate 22 includes a first arched clamping plate and a second arched clamping plate, and an arc-shaped connecting portion 222 is provided on the outer edge thereof for guiding the document access clip 4 to smoothly extend from the outside of the side plate 22 and clamp the document clip 2; the first arched clamping plate and the second arched clamping plate are respectively provided with a groove 221; the opening plate 23 is arranged on the opposite side of the positioning plate 21, and an openable connecting structure is provided between the opening plate 23 and the first arched clamping plate and the second arched clamping plate, so that the opening plate 23 can be opened or closed relative to the first arched clamping plate and the second arched clamping plate; the closing plate 24 is respectively connected to the positioning plate 21, the opening plate 23, the first arched clamping plate and the second arched clamping plate, and the protrusions of the first arched clamping plate and the second arched clamping plate face the outside of the document clip 2, and together form a closed space.

[0031] The arc-shaped connecting portion 222 is a smooth curved surface structure extending toward the outside of the side plate 22 , and the curvature radius thereof is adapted to the contour of the clamping end of the document access clip 4 .

[0032] The extending direction of the arc-shaped connecting portion 222 matches the movement trajectory of the clamping device, ensuring that the clamping device can automatically align along the curved surface when contacting the side plate 22. Through the design of the arc-shaped connecting portion 222 at the outer edge, the clamping device can quickly and accurately clamp the plastic plate assembly from the outside of the side plate (22), reducing operating friction or jamming, and avoiding clamping difficulties or structural damage caused by right-angle edges. The arc-shaped connecting portion 222 forms a lateral operating gap between adjacent document folders 2 when adjacent document folders 2 are stacked, so that the document access clip 4 can be easily inserted between the document folders 2 .

[0033] like Figure 3 , the fixing plate 401 is a rigid base, used to connect and support other components; The first end of the electric rotating shaft 404 is fixedly connected to the fixing plate 401, and the second end is connected to the fixing clamp 403, so as to drive the fixing clamp 403 to rotate around the axis; The fixing clamp 403 comprises a clamp plate and a clamp. The clamp plate is a plate-like structure connected to the electric rotating shaft, and its inner side is provided with a guiding inclined surface matching the arc-shaped connecting portion 222 of the side plate 22 of the document folder 2. The clamp is a clamping portion extending outward from the outer edge of the clamp plate, and its inner surface shape is adapted to the contour of the groove 221 of the side plate (22) of the document folder 2, and is used to be embedded in the groove 221 and fix the document folder 2 when clamping. The positioning clip 402 is disposed at the geometric center of the fixing clip 403 and is used to pull the document clip 2 out by a certain distance during the clamping process to ensure the clamping alignment accuracy of the fixing clip 403 .

[0034] like Figure 5The steps of the document access clip 4 for document clamping include: first, the control device identification code camera scans the document clip identification code of the document clip 2 to locate the target document clip 2; then, the control device document access clip 4 is aligned with the clamping groove 211 of the target document folder 2, and the positioning clip 402 hooks the clamping cross bar to pull the target document folder 2 out of the other adjacent folders by a certain distance, so that the fixing clip 403 can fit the arc-shaped connecting part 222 and clamp the groove 221 of the side plate (22); finally, after the fixing clip 403 completely clamps the document clip 2, the electric shaft 404 contracts to clamp the document clip 2 out of the document rack 1 and place it in the card slot in the storage frame 7.

[0035] The document access of the assemblable document access system comprises the following steps: S1, document rack assembly: based on the size of the documents, determine the number of document racks 1, assemble the document racks 1, set the access area, and continuously set the transmission device 501 and the fixed crossbar 6 on the side of each document rack 1 adjacent to the automatic storage surface until the access area; determine the total number of document folders 2 according to the number of documents, and set the position information of the space for storing document folders 2 on each document rack 1; S2, setting a folder identification code: after setting the document location information and basic document information of the blank folder 2 in the server, a folder identification code is generated, and the folder identification code is set on one side of the clamping slot 211 of the folder 2.

[0036] S3, document removal: after receiving the position information and the document access instruction information, the control device controls the transmission device 501 to move to the position of the document folder 2, and the document access folder 4 takes out the document folder 2 and puts it into the storage basket, and then moves to the access area; S4, document storage: after receiving the position information and the document access instruction information, the control device controls the transport fixed frame 502 to move to the position where the document folder 2 needs to be stored, and the document access folder 4 takes the document folder 2 out of the storage basket and places it on the corresponding position of the document rack 1.

[0037] The control device receives the location information and the document access instruction information, specifically including: The control device receives the location information and the document access instruction information through the server transmission; The control device directly receives the location information and document access instruction information by scanning the access identification code through the identification code camera.

[0038] Generally, the server transmits the location information and document access instruction information to the control device. If the network is disconnected, the identification code can be scanned by the identification code camera to directly transmit the location information and document access instruction information to the identification control device 8.

[0039] After receiving the position information and the document storage instruction information, the control device then fixes the document folder 2 in the storage frame 7; the control device controls the transmission device 501 to move to the position of the document folder 2, and scans whether there is other document folder 2 at the position of the document rack 1 corresponding to the position information. If not, the document access folder 4 stores the document folder 2 at that position; if so, the document access folder 4 clamps the wrongly located document folder 2 into the storage frame 7. After the document folder 2 to be stored is stored, the identification code camera scans the document folder identification code of the wrongly located document folder 2 in the storage basket. If it does not belong to the document folder 2 to be taken out, the control device repeats step S4.

[0040] After the control device receives the position information and the document retrieval instruction information, the control device controls the transmission device 501 to move to the position of the document folder 2, and scans whether there are other document folders 2 at the position of the document rack 1 corresponding to the position information. If so, the document access clip 4 clamps the document folder 2 into the storage basket, and the control device controls the transmission device 501 to move to the access area; if not, the identification code camera scans the identification codes of all document folders on the document rack 1. If the document folder 2 is on the document rack 1, the document retrieval action is performed normally. If it still does not exist, the document folder identification code is globally scanned until the correct document folder identification code is found, and then the above-mentioned retrieval action is performed; if there is a document folder 2 in the wrong position, after all the actions of retrieving the document folder 2 are completed, the position of the document folder 2 is restored according to the action of the wrong position of the document folder when the document folder is stored.
