[0077] Existing document packaging equipment occupies a large horizontal space.

[0078] The following is a preferred embodiment of a document packaging device provided by this utility model that can solve the above-mentioned technical problems.

[0079] A preferred embodiment of this utility model provides a document packaging device. Please refer to... Figure 1 The document packaging equipment includes an envelope conveyor line 1, an envelope dispensing module 2, an envelope opening module 3, an envelope feeding module 4, a paper dispensing module 5, and an envelope closing module 6.

[0080] Envelope conveyor line 1 is used to convey envelopes 100 (see) laterally. Figure 3 The envelope conveyor line 1 has four positions sequentially arranged on the conveying track of the envelope 100: a first position, a second position, a third position, and a fourth position. The envelope delivery module 2 is located on one longitudinal side of the envelope conveyor line 1 and is used to convey the envelope to the first position. The envelope opening module 3 is located at the second position and is used to open the envelope's flap. The envelope receiving module 4 is located at the third position and is used to receive the document 200 (see...) Figure 5 The document 200 is loaded into the envelope longitudinally. The paper dispensing module 5 and the envelope dispensing module 2 are located on the same longitudinal side of the envelope conveyor line 1. The paper dispensing module 5 is used to convey the document 200 to the envelope feeding module 4. The envelope closing module 6 is located at the fourth position and is used to close the envelope containing the document. In each figure, the x-direction is horizontal, the y-direction is vertical, and the z-direction is vertical.

[0081] This utility model discloses a document packaging device. Envelope delivery module 2 longitudinally transports envelopes to a first position; envelope conveyor line 1 transports envelopes to a second position; envelope opening module 3 opens the envelope's flap; envelope conveyor line 1 transports the envelope to a third position; paper delivery module 5 longitudinally transports documents to envelope insertion module 4; envelope insertion module 4 longitudinally inserts the documents into the envelopes; envelope conveyor line 1 transports the envelopes to a fourth position; and envelope closing module 6 closes the envelopes containing the documents. In this document packaging device, both envelope delivery module 2 and paper delivery module 5 are located on the same longitudinal side of envelope conveyor line 1, effectively reducing the lateral space occupied by the document packaging device and facilitating placement.

[0082] Please refer to Figure 2The envelope dispensing module 2 includes an envelope hopper 21, an envelope clamping structure 22, an envelope dispensing suction cup assembly 23, and an envelope dispensing rotary drive mechanism 24. The envelope hopper 21 holds multiple envelopes and is inclined, with its two longitudinal ends being a first end and a second end, respectively. The first end is closer to a first position relative to the second end and is lower than the second end. The first end has an envelope outlet. The envelope clamping structure 22 is disposed in the envelope hopper 21 and moves along the direction from the second end to the first end to push the envelopes to the envelope outlet. The envelope dispensing suction cup assembly 23 is rotatably disposed at the envelope outlet. The envelope dispensing rotary drive mechanism 24 is connected to the envelope dispensing suction cup assembly 23 to transport the envelopes located at the envelope outlet to the first position.

[0083] During operation, a stack of envelopes is placed in the envelope hopper 21. Because the first end is lower than the second end, the envelopes can move from the second end to the first end. The envelope clamping structure 22 ensures a tight supply of vertically positioned envelopes, preventing supply interruptions or collapse. Since the envelope clamping structure 22 is movably placed in the envelope hopper 21 without rigid screw connections, during feeding, it can be easily and quickly moved backward manually. The envelope suction cup assembly 23 picks up envelopes located at the envelope outlet. The envelope rotation drive mechanism 24 drives the envelope suction cup assembly 23 to rotate, transporting the envelopes from the outlet to the first position. Using this structure, a stack of envelopes can be fed at once, automatically transporting each envelope from the outlet to the first position.

[0084] The material bin 21 may be equipped with a conveyor belt to move the envelope 100 from the second end to the first end, further preventing the problem of envelope 100 supply interruption. During operation, the envelope is placed on the conveyor belt, and the conveyor belt moves the envelope to achieve envelope supply.

[0085] The envelope container 21 is equipped with a width adjustment structure 25 for adjusting the width of the envelope container 21. The width adjustment structure 25 can adjust the width of the envelope container 21 by adjusting the distance between the two lateral opposite side walls of the envelope container 21, and can accommodate envelopes of different sizes.

[0086] Please refer to Figure 3A clamp 11 is provided on the envelope conveyor line 1 to position the envelope on the conveyor line 1. The envelope opening module 3 includes an adjusting structure 31, a pressing structure 32, and an envelope opening guide structure 33. The adjusting structure 31 is arranged laterally to push the envelope into the clamp 11. The pressing structure 32 is arranged on one longitudinal side of the envelope conveyor line 1 and is used to apply pressure to the seal of the envelope to make the seal flap curl up. The envelope opening guide structure 33 is arranged above the envelope conveyor line 1. When the envelope conveyor line 1 conveys the envelope to the second position, the envelope opening guide structure 33 is inserted into the seal of the envelope, so that the free end of the seal flap flips open around the connection between the seal flap and the body, and the seal flap unfolds flat.

[0087] When clip 11 is open, the adjusting structure 31 moves laterally to push one side of the envelope into clip 11. After clip 11 closes, the envelope can move laterally under the drive of envelope conveyor line 1. Envelope conveyor line 1 transports the envelope to the second position, with one end of the envelope opening facing the sealing structure 32. During this transport process, the sealing structure 32 applies a certain downward pressure to the envelope opening, causing the connection between the flap and the envelope body to move downward, thus causing the flap to tilt relative to the envelope body. The envelope continues to move laterally, and when it passes below the envelope opening guide structure 33, the envelope opening guide structure 33 inserts between the flap and the envelope body. The free end of the flap flips open around the connection between the flap and the body, separating the free end of the flap from the envelope body and allowing the flap to unfold flat. Using the above structure, the envelope flap can be automatically opened and flattened, facilitating the subsequent loading of documents.

[0088] Please refer to Figure 4 and Figure 5 The paper dispensing module 5 includes a document conveying line 51 and a first paper dispensing mechanism 52. The document conveying line 51 is used to convey documents 200 longitudinally to the envelope feeding module 4. The first paper dispensing mechanism 52 includes a first carton 521, a tray 522, a vertical driver (not shown), a document suction cup assembly 523, and a suction cup drive assembly 524. The top of the first carton 521 is open. The tray 522 is vertically disposed in the first carton 521 and is used to carry the documents 200. The vertical driver is connected to the tray 522 and is used to drive the tray 522 to move vertically. The document suction cup assembly 523 is movable. The suction cup drive assembly 524 is connected to the document suction cup assembly 523 and is used to drive the document suction cup assembly 523 to move so as to input the documents from the first carton 521 onto the document conveying line 51.

[0089] During operation, a stack of documents is placed flat on tray 522. Document suction cup assembly 523 adsorbs the top document in the first cardboard box 521, while documents below fall under their own weight without being lifted. Alternatively, the suction force can be reduced so that only one document is picked up at a time. Suction cup drive assembly 524 drives document suction cup assembly 523 to move, feeding documents from the first cardboard box 521 onto document conveyor line 51. As the number of documents decreases, a vertical driver drives tray 522 upwards, ensuring the top of the document on tray 522 is always at a set height so that document suction cup assembly 523 can hold it. The first paper dispensing mechanism 52 is suitable for dispensing larger or heavier documents. Using this structure, a stack of documents can be loaded at once, automatically conveying each document to document conveyor line 51. The first cardboard box 521 can also be detachably equipped with two horizontally opposing limiting plates. By changing the distance between the limiting plates, the first cardboard box 521 can be compatible with smaller certificates.

[0090] Please refer to Figure 6 and Figure 7 The paper dispensing module 5 includes a document conveying line 51 and a second paper dispensing mechanism 53. The document conveying line 51 is used to convey documents longitudinally to the envelope feeding module 4. The second paper dispensing mechanism 53 includes a second carton 531, a blower assembly 532, a suction wheel assembly 533, and a suction wheel drive structure 534. The bottom of the second carton 531 has an opening. The blower assembly 532 is located on one side of the second carton 531 and is used to blow air into the second carton 531 to lift the upper documents in the second carton 531. The suction wheel assembly 533 is located below the opening and is used to suck up the bottommost document in the second carton 531. The suction wheel drive structure 534 is connected to the suction wheel assembly 533 and is used to convey the documents sucked up by the suction wheel assembly 533 to the document conveying line 51.

[0091] During operation, a stack of documents is placed flat in the second cardboard box 531. The suction wheel assembly 533 sucks up the bottom document in the second cardboard box 531, while the blower assembly 532 blows up the other documents in the second cardboard box 531 to reduce the pressure of the upper documents on the bottom document. The suction wheel drive structure 534 drives the suction wheel assembly 533 to rotate, thereby conveying the bottom document of the second cardboard box 531 to the document conveying line 51. The second paper dispensing mechanism 53 is suitable for dispensing smaller or lighter documents. The second paper dispensing mechanism 53 also includes a double-sheet detector 535, which is located on the side of the second cardboard box 531 near the envelope module 4. If the double-sheet detector 535 detects a single document, normal output occurs. If the double-sheet detector 535 detects two documents, an alarm is triggered, and manual handling is required.

[0092] Please refer to Figure 4 , Figure 5 , Figure 6and Figure 7 The first cardboard box 521 is slidably arranged longitudinally. The second paper dispensing mechanism 53 is located on the side of the first paper dispensing mechanism 52 near the envelope module 4. The second paper dispensing mechanism 53 and the first paper dispensing mechanism 52 are respectively used to transport documents of different sizes to the envelope module 4. Specifically, the first cardboard box 521 and the second cardboard box 531 are respectively used to hold documents of different sizes.

[0093] The first paper dispensing mechanism 52 and the second paper dispensing mechanism 53 can convey two commonly used documents of different sizes, improving compatibility. For example, the first paper dispensing mechanism 52 conveys A3-sized documents, and the second paper dispensing mechanism 53 conveys A4-sized documents. The second paper dispensing mechanism 53 is located on the side of the first paper dispensing mechanism 52 closer to the envelope module 4, and will not interfere with the longitudinal sliding arrangement of the first carton 521, making the structure more compact.

[0094] Please refer to Figure 4 The document conveyor line 51 is equipped with a manual paper placement station 511, located on the side of the second paper dispensing mechanism 53 near the envelope feeding module 4. For documents with a small quantity but many categories, they can be manually placed on the manual paper placement station 511 for conveying, improving the equipment's compatibility. The paper dispensing module 5 also includes a camera recognition module 54, located on the side of the manual paper placement station 511 near the envelope feeding module 4, used to recognize documents. If the recognition is successful, the document conveyor line 51 will convey the document to the envelope feeding module 4.

[0095] Please refer to Figure 8 The envelope module 4 includes an envelope opening suction cup mechanism 41, a document clamping and conveying mechanism 42, a document check mechanism 43, and a document pressing mechanism 44. The envelope opening suction cup mechanism 41 is vertically movable and used to open the envelope. The document clamping and conveying mechanism 42 is vertically movable and has a receiving cavity for receiving documents. Both ends of the receiving cavity are open, and a notch 421 is provided at the end of the document clamping and conveying mechanism 42 facing away from the paper dispensing module 5. The document check mechanism 43 is connected to the end of the document clamping and conveying mechanism 42 near the paper dispensing module 5 and is vertically movable. The document pressing mechanism 44 is vertically movable and used to press the documents and envelope through the notch 421.

[0096] Since both ends of the receiving cavity are open, when the paper dispensing module 5 conveys documents longitudinally, documents can be fed into the receiving cavity from one end. The document check mechanism 43 moves down to block one end of the receiving cavity, preventing the documents from retracting. The document clamping and conveying mechanism 42 moves longitudinally and inserts into the envelope. The document pressing mechanism 44 moves down and presses the document and envelope together at the notch 421. The document clamping and conveying mechanism 42 then exits the envelope, leaving the document inside. With this structure, documents can be automatically loaded into envelopes, and the documents are less prone to wrinkling.

[0097] Please refer to Figure 9 The envelope closing module 6 includes an envelope opening straightening mechanism 61, a glue spraying module (not shown in the figure), an envelope closing device 62, and an envelope closing pressing mechanism 63. The envelope opening straightening mechanism 61 bends the envelope flap from a horizontal to a vertical position. The glue spraying module is located at the envelope opening straightening mechanism 61 and sprays glue onto the flap or body of the envelope 100. The envelope closing device 62 is located on the side of the envelope opening straightening mechanism 61 opposite to the envelope module 4. The envelope closing device 62 is longitudinally movable and is used to close the envelope flap. The envelope closing pressing mechanism 63 is located on the side of the envelope closing device 62 opposite to the envelope opening straightening mechanism 61 and is used to press the envelope flap firmly against the body of the envelope.

[0098] Please refer to Figure 9 As the envelope moves laterally past the envelope opening straightening mechanism 61, the mechanism straightens the envelope's flap, while the glue spraying module sprays glue onto the flap or the body of the envelope. The envelope then moves laterally to the longitudinal side of the envelope closing device 62, which moves longitudinally to close the flap and retracts. The envelope continues to move laterally to the envelope closing and pressing mechanism 63, which presses the envelope's flap firmly against the body of the envelope. This structure automatically closes and presses the envelope opening.

[0099] Please refer to Figure 1 and Figure 10 The envelope conveyor line 1 also includes a fifth position, located on the side opposite to the third position of the fourth position. The document sealing equipment also includes a labeling module 7, which is located at the fifth position. The labeling module 7 includes a labeler 71 and a brush 72. The labeler 71 is used to print documents, such as thermal forms. The brush 72 is located on the side of the labeler 71 opposite to the envelope closing module 6 and is used to apply pressure to the documents.

[0100] An envelope containing documents is fed to a labeling machine 71, which prints out the documents and affixes them to the surface of the envelope. As the envelope moves past a brush 72, the brush 72 secures the documents to the envelope. The labeling module 7 can automatically affix documents to the envelope.

[0101] Working principle of the document packaging device of the preferred embodiment of this utility model:

[0102] A stack of envelopes is placed in the envelope hopper 21, and the envelope clamping structure 22 is placed at the rear of the envelopes, allowing the envelopes to move from the second end to the first end. The envelope dispensing rotation drive mechanism 24 drives the envelope dispensing suction cup assembly 23 to rotate, conveying the envelopes located at the envelope outlet to the first position.

[0103] When the clip 11 is in the open state, the adjusting structure 31 moves laterally to push one side of the envelope into the clip 11. After the clip 11 is closed, the envelope can move laterally under the drive of the envelope conveyor line 1. The envelope conveyor line 1 transports the envelope to the second position, with one end of the envelope opening facing the sealing structure 32. During this transport process, the sealing structure 32 applies a certain downward pressure to the envelope opening, causing the connection between the flap and the envelope body to move downward, thus causing the flap of the envelope to curl up relative to the envelope body. The envelope continues to move laterally, and when it passes below the envelope opening guide structure 33, the envelope opening guide structure 33 is inserted between the flap and the envelope body. The free end of the flap flips open around the connection between the flap and the body, separating the free end of the flap from the body of the envelope and making the flap unfold flat.

[0104] For large documents, a stack of documents is placed flat on tray 522. The document suction cup assembly 523 picks up the top document in the first cardboard box 521, while the documents below fall under their own weight and are not lifted up. This also reduces the suction force, allowing only one paper to be picked up at a time. The suction cup drive assembly 524 drives the document suction cup assembly 523 to move, thus feeding the documents from the first cardboard box 521 onto the document conveyor line 51. As the number of documents decreases, the vertical driver drives tray 522 to move upward, ensuring that the top paper on tray 522 is always at a set height so that the suction cup drive assembly 524 can hold the documents.

[0105] For small documents, a stack of documents is placed flat in the second cardboard box 531. The suction wheel assembly 533 sucks up the bottom document in the second cardboard box 531, and the blower assembly 532 blows up the other documents in the second cardboard box 531 to reduce the pressure of the upper documents on the bottom document. The suction wheel drive structure 534 drives the suction wheel assembly 533 to rotate, thereby conveying the bottom document of the second cardboard box 531 to the document conveyor line 51.

[0106] For documents with a small quantity but many categories, they can be manually placed on the manual paper feeding station 511 for transport.

[0107] Since both ends of the receiving cavity are open, when the paper dispensing module 5 conveys the document longitudinally, it can convey the document from one end of the receiving cavity into the receiving cavity. The document check mechanism 43 moves down to block one end of the receiving cavity, preventing the document from retracting. The document clamping and conveying mechanism 42 moves longitudinally and inserts into the envelope. The document pressing mechanism 44 moves down and presses the document and envelope at the notch 421. The document clamping and conveying mechanism 42 then exits the envelope, leaving the document inside the envelope.

[0108] The envelope moves to the envelope flap straightening mechanism 61, straightening the envelope flap, while the glue spraying module sprays glue onto the envelope flap or the envelope body. The envelope then moves laterally to below the envelope closing device 62, which moves down and rotates to close the envelope flap, then moves up. The envelope continues to move laterally to the envelope closing pressing mechanism 63, which presses the envelope body firmly against the sealing mechanism.

[0109] Envelopes containing documents are fed to labeling machine 71, which prints out thermal forms and affixes them to the envelope surface. As the envelope moves past brush 72, the brush 72 secures the thermal forms to the envelope. The labeling module 7 can automatically affix thermal forms to the envelope.

[0110] This completes the assembly process of the document packaging device of this preferred embodiment.

[0111] This utility model discloses a document packaging device. An envelope dispensing module longitudinally transports an envelope to a first position; an envelope conveyor line transports the envelope to a second position; an envelope opening module opens the envelope's flap; the envelope conveyor line transports the envelope to a third position; a paper dispensing module longitudinally transports the document to an envelope receiving module; the envelope receiving module longitudinally inserts the document into the envelope; the envelope conveyor line transports the envelope to a fourth position; and an envelope closing module closes the envelope containing the document. In this document packaging device, both the envelope dispensing module and the paper dispensing module are located on the same longitudinal side of the envelope conveyor line, effectively reducing the lateral space occupied by the document packaging device and facilitating placement.

[0112] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the concept of the technical solution of the present invention, should be included within the scope of protection of the present invention.
