[0032] The following will be combined with the attached Figure 1 To Attachment Fig.11 The technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that if there are directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention, the directional indications are only used to explain the relative position relationship and movement of the components under a certain posture (as shown in the attached drawings). If the certain posture changes, the directional indications will also change accordingly. Figure 1 The display is subject to Figure 1 The upper part of the device is directed to the rear, the lower part is directed to the front, the upward direction of the vertical first transmission device 1 is the upper direction, and the corresponding downward direction is the lower direction; Figure 1 The processing direction is from left to right.

[0034] The present invention proposes a mailing envelope packaging device, which is mainly used for opening envelopes, letter loading, sealing, labeling and testing, and realizes automatic production. The envelope is a structure of an envelope body and a sealing part; the letter can be various forms of documents, electronic cards, etc. Figure 1 The position shown is the standard, the right side along the processing direction is the front end, and the left side is the rear end.

[0035] For details, see Figure 1 and Figure 2 In this scheme, a mail envelope packaging device comprises a first transmission device 1, a second transmission device 2, an envelope feeding device 3, an envelope sealing opening device 4, a letter feeding device 5, a glue spraying device 6, a sealing device 7, a labeling device 8, a code scanning device 9, a weighing device 10, a waste material removal device 11, a material receiving device 12 and an industrial computer 13. The industrial computer 13 is respectively connected to the first transmission device 1, the second transmission device 2, the envelope feeding device 3, the envelope sealing opening device 4, the letter feeding device 5, the glue spraying device 6, the sealing device 7, the labeling device 8, the code scanning device 9, the weighing device 10, the waste material removal device 11 and the material receiving device 12, and is used to control the coordinated work of these devices. Among them, the envelope feeding device 3, the envelope sealing opening device 4, the letter feeding device 5, the glue spraying device 6, the sealing device 7, the labeling device 8, and the code scanning device 9 are arranged along the processing direction of the first transmission device 1.

[0036] Specifically, the mailing packaging device has a support 100, on which a first transmission device 1 and a second transmission device 2 are arranged, and the first transmission device 1 and the second transmission device 2 are arranged in sequence along the processing direction. Figure 2 and Figure 3 The first transmission device 1 has a plurality of pairs of clamping members 110 for clamping envelopes, and a clamping position 120 for placing envelopes is formed between adjacent pairs of clamping members 110. When working, the clamping members 110 are used to clamp envelopes, and the length of the clamping position 120 is greater than the length of the envelope, which makes it more convenient to clamp the envelope. Specifically, in this embodiment, the first transmission device 1 is implemented by using the known belt transmission technology, and the second transmission device 2 is implemented by using the known cardboard belt technology, such as Figure 3 As shown, the card conveyor belt 21 of the second transmission device 2 is arranged above the working platform. That is, the second transmission device 2 is arranged above the working platform, and the movement of the envelope is realized by pushing the envelope above the envelope, and no pressure is generated on the envelope in the height direction. In addition, it should be understood that in the scheme of the present invention, the first transmission device 1 is located on the side away from the envelope feeding device 3 and an adjustable baffle 130 is arranged along the length direction of the first transmission device 1 to limit the effective width of the card position 120. That is, the width of the card position 120 can be set according to the width of the envelope to meet the mailing requirements of different envelopes. Specifically, the baffle 130 is arranged along the length of the first transmission device 1. Among them, the position adjustment of the baffle 130 is achieved by fixing it at different positions of the bracket 100. For example, corresponding fixing grooves can be set at different positions of the bracket 100, and the baffle 130 can be fixed in the fixing groove when in use. Or a threaded screw mechanism is used to achieve the position adjustment of the baffle 130.

[0037] See also Figure 4, which is a schematic diagram of the structure of the envelope feeding device 3. The envelope feeding device 3 has a feeding mechanism 31 and a pushing mechanism 32, and the pushing mechanism 32 is used to push the envelope placed by the feeding mechanism 31 at the said card position 12 to the set position. The feeding mechanism 31 has an envelope feeding trough 311 and a rotating envelope grabbing mechanism 312, and the envelope is placed in the envelope feeding trough 311. The rotating envelope grabbing mechanism 312 is located at the outlet end of the envelope feeding trough 311 and above the first transmission device 1, and is used to grab the envelope and place it at the card position 120 of the first transmission device 1. It should be understood that in the present technical solution, the rotating envelope grabbing mechanism 312 is implemented by a well-known structure, so it will not be repeated in this embodiment. When working, the rotating envelope grabbing mechanism 312 can place the envelope at the card position 120 in a timely and accurate manner.

[0038] See also Figure 5 , which is a schematic diagram of the structure of the envelope seal opening device 4. The envelope seal opening device 4 is used to open the seal of the envelope transmitted by the first transmission device 1 and make the inner side of the seal face up and open the opening of the envelope. Through this operation, the opening of the envelope can be opened, which is convenient for the subsequent letters to be put in. Specifically, along the processing direction, the envelope seal opening device 4 has a blowing mechanism 41, a guide plate 42, a pressing plate 43 and a limiting plate 44. The blowing mechanism 41 is located above the first transmission device 1 and is used to blow open the seal of the envelope and make a gap between the seal and the envelope body; the blowing mechanism 41 includes an air nozzle 411 and an air pump connected to the air nozzle 411 (not shown in the figure). The air pump is connected to the industrial computer 13, and the operation of the air pump is controlled by the industrial computer 13. Specifically, as Figure 6As shown, the air nozzle 411 is arranged obliquely from the front upper direction to the rear lower direction, and the air outlet of the air nozzle 411 is directly opposite to the junction of the sealing part and the envelope body of the envelope. In this way, the airflow blown by the air nozzle 411 can blow the sealing part of the envelope upward, so that there is a gap between the sealing part and the envelope body, which is convenient for the subsequent sealing opening. The guide plate 42 has an inclined flat plate portion 421 and a folding edge portion 422 inclined upward from the side of the flat plate portion 421, and a first flared inclined portion 423 is provided at one end of the flat plate portion 421 close to the blowing mechanism 41. In this embodiment, the folding edge portion 422 is inclined toward the rear upper direction, and the first flared inclined portion 423 is inclined from the upper left direction to the rear lower direction. The first flared inclined portion 423 facilitates the pressing of the envelope body into the flat plate portion 421. The pressing sheet 43 is inclined downward from the top of the folding edge portion 422 to the processing direction. The pressing plate 43 can make the sealing part after being turned over by the folding part 422 smoother and gentler, so as to facilitate entering the limiting piece 44. Specifically, the limiting piece 44 is located at the tail of the pressing piece 43 along the processing direction and is arranged parallel to the transmission plane of the first transmission device 1. The limiting piece 44 has a second flared inclined portion 441 at one end close to the pressing piece 43. The second flared inclined portion 441 can facilitate pressing the turned sealing part under the limiting piece 44, so that the sealing part will not block the opening of the envelope. During specific operation, the air nozzle 411 blows up the sealing part of the envelope, so that there is a gap between the sealing part and the envelope body; with the transmission of the first transmission device 1, the envelope is transmitted to the first expansion inclined part 423, and the first expansion inclined part 423 allows the envelope body of the envelope to enter the lower part of the flat plate part 421. With further transmission, the sealing part of the envelope is stuck in the flat plate part 421, so that the envelope body and the sealing part of the envelope are respectively located below and above the flat plate part 421. With further transmission, the sealing part is lifted by the folding part 422 to realize flipping, and after flipping, it enters the lower part of the pressing sheet 43 and is guided to the limiting sheet 44. The sealing part of the envelope is opened and flipped by this technology. At the same time, due to the pre-blowing effect of the air nozzle 411, a gap can be created between the sealing part and the envelope body, which makes it convenient for the subsequent flat plate part 421 to be inserted into the gap between the sealing part and the envelope body; this can ensure that the sealing part of the envelope is opened more smoothly, and avoid the problem that some adsorption energy sealing parts cannot be lifted at the flat plate part 421.

[0039] See also Figure 7, which is a schematic diagram of the structure of the letter feeding device 5. The letter feeding device 5 has a letter transfer mechanism 51, a letter transmission mechanism 52, a letter acceleration mechanism 53 and an adsorption mechanism 57. The letter acceleration mechanism 53 is located at the front end of the letter transmission mechanism 52. The letter transmission mechanism 52 is used to receive the letter transferred by the letter transfer mechanism 51 and transmit the letter to the front end. The adsorption mechanism 57 is used to absorb and open part of the envelope body upward so that the envelope body receives the letter thrown by the letter acceleration mechanism 53. Specifically, the letter feeding device 5 is arranged on one side of the first transmission device 1 and is arranged on the same side as the envelope feeding device 3. Its purpose is to open the inner cavity of the envelope body and throw the letter into the inner cavity. The structure of the letter transfer mechanism 51 is the same as that of the envelope feeding device 3, and both are implemented by existing well-known devices, which will not be repeated here. It is achieved by adsorbing the letter at the material trough and transferring it to the letter transmission mechanism 52. It should be understood that the letter transmission mechanism 52 is implemented by a known cardboard transmission belt, that is, a card slot for placing letters is formed on the cardboard transmission belt, and the cardboard transmission belt is driven by a motor. A letter acceleration mechanism 53 is provided at the front end of the letter transmission mechanism 52, and the letter acceleration mechanism 53 is used to accelerate the letter at the front end of the letter transmission mechanism 52 so that the speed of the letter is greater than the transfer speed of the letter transmission mechanism 52. In this way, the letter is thrown out at the front end of the letter transmission mechanism 52. At the same time, it should be understood that the adsorption mechanism 57 is provided above the first transmission device 1, and the adsorption mechanism 57 is located on the front side of the letter transmission mechanism 52, which is used to adsorb the upper part of the envelope body so that the opening of the envelope body is opened, so that a cavity is formed in the envelope. The cavity is directly opposite to the front end of the letter transmission mechanism 52, so that the letter accelerated and thrown out by the letter acceleration mechanism 53 is put into the cavity of the envelope, so that the bagging operation of the letter is realized. It should be understood that the adsorption mechanism 57 can be implemented by using a known technology. For example, it can be achieved by setting up a cylinder 571 and an adsorption component, the adsorption component includes a plurality of suction nozzles 572 and a vacuum pump (not shown in the figure) connected to the plurality of suction nozzles 572, the cylinder 571 is vertically arranged above the first transmission device 1 and fixedly connected to the bracket 100, and its output end is fixedly connected to the plurality of suction nozzles 572 through a fixed plate, the cylinder 571 and the vacuum pump are connected to the industrial computer 13, when working, the cylinder 571 moves down until the suction nozzle 572 contacts the envelope body, and then the vacuum pump works at the suction nozzle 572 to generate negative pressure, the suction nozzle 572 adsorbs the envelope body, the cylinder 571 moves up, the envelope body is opened to form a cavity, the letter acceleration mechanism 53 puts the letter into the cavity of the envelope body, and then the vacuum pump releases pressure.

[0040] See also Figure 8, which is a schematic diagram of the structure of the letter transmission mechanism 52 and the letter acceleration mechanism 53. In this embodiment, the letter transmission mechanism 52 and the letter acceleration mechanism 53 use the same power source to achieve power output. Specifically, the letter transmission mechanism 52 has two transfer conveyor belts 521, a driving shaft 522, a driven shaft 523 and a transfer motor 524 arranged at intervals, the two transfer conveyor belts 521 are sleeved on the driving shaft 522 and the driven shaft 523, and the transfer motor 524 is connected to the driving shaft 522 in a transmission manner; the letter acceleration mechanism 53 has at least one acceleration component located above the transfer conveyor belt 521, the at least one acceleration component is arranged close to the first transmission device 1, and the acceleration component includes a connecting shaft 531 and friction wheels 532 fixed at both ends of the connecting shaft 531; wherein the rotation direction of the friction wheel 532 is opposite to the rotation direction of the driving shaft 522, and the linear speed of the edge of the friction wheel 532 is greater than the moving speed of the transfer conveyor belt 521. In this embodiment, the letter acceleration mechanism 53 is located above the front end of the letter transmission mechanism 52. Therefore, in order to achieve acceleration, the rotation direction of the friction wheel 532 is opposite to the rotation direction of the active shaft 522. Figure 8 As shown, when the active shaft 522 rotates clockwise, the friction wheel 532 rotates counterclockwise. And the linear speed of the edge of the friction wheel 532 is greater than the transmission speed of the transfer conveyor belt 521, so that the letter can be accelerated. Specifically, the power is transmitted between the transfer motor 524, the active shaft 522 and the friction wheel 532 through the belt. In addition, in order to ensure that the letter is thrown out stably after acceleration, two groups of parallel acceleration components are provided in this embodiment. In some other embodiments, the connecting shaft 531 of the acceleration component can also be connected to an independent motor to provide power to meet the needs.

[0041] Specifically, the letter feeding device 5 also has an auxiliary pulley 54, and the output end of the transfer motor 524 is connected to the connecting shaft 531, the driving shaft 522 and the auxiliary pulley 54 through a transmission belt 55 so that the connecting shaft 531 and the driving shaft 522 rotate in opposite directions. Figure 8 The method shown is implemented, but not limited to this, and any suitable method can be adopted, as long as the friction wheel 532 and the active shaft 522 are rotated in opposite directions. It should be understood that in this embodiment, the friction wheel 532 generates a friction force pointing to the direction of the first transmission device 1 on the letter when it contacts the letter, and the friction force accelerates the letter.

[0042] More preferably, in order to adapt to the packaging of electronic cards, such as credit cards, a card reader (not shown) is provided below the letter transport mechanism 51, and the card reader is connected to the industrial computer 13 to detect whether there is an electronic card in the letter transmitted by the letter transport mechanism 51. That is, the card reader can know whether there is an electronic card in the letter, and if not, the signal is fed back to the industrial computer 13, and the industrial computer 13 controls the waste rejection device 11 to open according to the corresponding relationship to reject the corresponding envelope.

[0043] A glue spraying device 6 is provided at the front end of the letter feeding device 5. The glue spraying device 6 is located above the first transmission device 1 and is used to spray glue onto the inner side of the sealing portion of the envelope. The glue spraying device 6 is connected to the industrial computer 13, and the industrial computer 13 sprays glue according to the process. Specifically, the glue spraying device 6 is facing the inner side of the sealing portion, and the glue can be sprayed when needed. The glue spraying device 6 can be implemented by a known glue spraying machine, for example, a glue dispensing glue spraying machine can be used.

[0044] In this embodiment, the sealing device 7 is used to turn back and compact the sealing portion of the envelope to achieve sealing. The sealing device 7 can be implemented using known technology. For example, see Fig. 9 The sealing device 7 includes a guide plate 71, a flanging plate 72, a compacting plate 73 and a pressure wheel 74. The guide plate 71 is tilted upward from left to right, so that the sealing part is flipped inward at a certain angle under the action of the guide plate 71. The flanging plate 72 is an inclined member that continuously increases from left to right. Under the action of the flanging plate 72, the inner side surface of the sealing part is flipped to face the envelope body. During the continuous movement of the envelope, the flipped sealing part and the envelope body are introduced into the compacting plate 73, and the compacting plate 73 compacts and bonds the sealing part and the envelope body. In order to further bond, a pressure wheel 74 is used for further compaction.

[0045] In this embodiment, a labeling device 8 is used to attach labels to envelopes. The labeling device 8 is arranged above the first transmission device 1, and attaches letter labels to the surface of envelopes. The labeling device 8 can be implemented by a known labeling machine.

[0046] At the front end of the labeling device 8 is a code scanning device 9, which is located above the end of the first transmission device 1 and is used to scan the label on the envelope. The code scanning device 9 is connected to the industrial computer 13 and is used to transmit the information obtained by scanning the code to the industrial computer 13. The code scanning device 9 adopts a well-known code scanning machine, which can be a two-dimensional code scanning machine or a barcode scanning machine, or a multifunctional scanning machine combining two-dimensional code scanning and barcode scanning.

[0047] In this embodiment, the front end (i.e. Figure 1The right side of the figure is the second transmission device 2. The mailing packaging device has a weighing device 10 and a waste rejection device 11 along the processing direction of the second transmission device 2. The weighing device 10 is used to obtain the total amount of letters after packaging and labeling, and the waste rejection device 11 is used to reject letters that do not meet the requirements.

[0048] Specifically, the weighing device 10 is arranged between the effective transmission strokes of the second transmission device 2, and is used to weigh the weight of the envelope. The effective transmission stroke refers to any suitable part arranged between the two ends of the second transmission device 2. The weighing device 10 is connected to the industrial computer 13, and is used to transmit the weighed weight of the letter to the industrial computer 13 for the industrial computer 13 to monitor and control the waste rejection device 11 to open to reject the letter when unqualified. It should be understood that in this embodiment, the weighing plane 101 of the weighing device 10 is higher than the second transmission plane 22 of the second transmission device 2. This ensures that the weighing device 10 will not be affected during weighing, thereby causing errors. Among them, the weighing device 10 is implemented using well-known equipment, see Fig.10 .

[0049] See also Fig.10 and Fig.11 The waste rejection device 11 is located at the front end of the weighing device 10 and forms a waste gap 111 between the waste rejection device 11 and the weighing plane 101 of the weighing device 10 when it is started, so that the envelope can pass through.

[0050] The waste rejection device 11 has a rotating plate 112 and a lifting mechanism 113 located at the front end of the weighing device 10; the front end of the rotating plate 112 is pivotally connected to the bracket 100, and the rear end thereof is fixedly connected to the lifting mechanism 113; when the lifting mechanism 113 outputs upward, the rotating plate 112 and the weighing plane 101 of the weighing device 10 are offset to form the waste gap 111, and when the lifting mechanism 113 outputs downward, the rotating plate 112 and the weighing plane 101 are directly opposite to each other so that the waste gap 111 is closed. This embodiment realizes the closing or opening of the waste opening 111 by controlling the position between the weighing plane 101 and the rotating plate 112. When closed, the weighing plane 101 and the rotating plate 112 are in contact with each other, so that the envelope on the weighing plane 101 can pass through the upper surface of the rotating plate 112 and be transmitted to the receiving device 12. When opened, the rotating plate 112 is rotated to be located above the weighing plane 101, and the waste gap 111 between the two is exposed. Under the action of the second transmission device 2, the waste gap 111 outputs the envelope, that is, it is rejected.

[0051] In detail, the lifting mechanism 113 includes a driving motor 1131 fixed on the bracket 100, the output end of the driving motor 1131 is connected to a connecting plate 1132, the two ends of the connecting plate 1132 are respectively connected to a vertical plate 1133, the two vertical plates 1133 are respectively slidably connected to the rotating plate 112, and the connecting plate 1132 and the rotating plate 112 form the waste gap 111. That is, in this embodiment, the waste gap 111 is moved up and down by the action of the driving motor 1131. When the waste gap 111 moves up, it is exposed on the weighing plane 101, and when it moves down, the waste gap 111 is sunken. Among them, the two ends of the rotating plate 112 have connecting columns 1121, and the connecting columns 1121 are slidably connected to the slide groove 11331 set on the vertical plate 1133, that is, the connecting columns 1121 can slide in the slide groove 11331, and the rotation of the rotating plate 112 can be ensured by this design. Specifically, the driving motor 1131 is connected to the industrial computer 13, and the industrial computer 13 controls the operation of the driving motor 1131. In addition, it should be noted that the driving motor 1131 is a linear motor capable of outputting linear motion, or any suitable power device thereof. In order to recycle discarded envelopes, a storage box 114 for receiving discarded envelopes is provided below the waste rejection device 11. Envelopes falling from the waste notch 111 will fall into the storage box 114.

[0052] In this embodiment, the receiving device 12 is located at the end of the second transmission device 2 and is used to receive the packaged envelopes. The receiving device 12 can be implemented by an existing device.

[0053] In detail, in this scheme, the first transmission device 1, the second transmission device 2, the envelope feeding device 3, the envelope sealing and opening device 4, the letter feeding device 5, the glue spraying device 6, the sealing device 7, the labeling device 8, the code scanning device 9, the weighing device 10, the waste material removal device 11 and the material receiving device 12 are connected to the industrial computer 13, and the industrial computer 13 is used to control the operation of each device. The control of the industrial computer 13 adopts an established execution scheme for control, and the execution scheme can be implemented using well-known technologies.

[0054] Working principle:

[0055] The feeding mechanism 31 of the envelope feeding device 3 transfers the envelope to the clamping position 120 of the first transmission device 1, and the pushing mechanism 32 pushes the envelope to the position in contact with the baffle 130; then the clamping member 110 clamps the envelope. The blowing mechanism 41 blows the sealing part of the envelope open and has a gap, and the envelope is transmitted to the guide plate 42, and then the sealing part is opened after the action of the guide plate 42, the pressing plate 43 and the limiting plate 44, and its inner side is set upward. The adsorption mechanism 57 adsorbs the envelope body and pulls it up, so that the opening is opened, and the envelope body forms a cavity. Under the action of the letter acceleration mechanism 53, the letter transmitted by the letter transmission mechanism 52 is accelerated by the letter acceleration mechanism 53 and then put into the cavity of the envelope body. When the sealing part reaches the glue spraying device 6, the industrial computer 13 controls the glue spraying device 6 to spray glue on the sealing part until the inner side of the entire sealing part is sprayed with glue. The sealing part is turned over and attached after passing through the sealing device 7. When it is transmitted to the labeling device 8, the labeling process is implemented, and the specific label is attached to the interface between the sealing part and the envelope body. The information of the envelope is obtained by scanning the code scanning device 9 at the front end of the first transmission device 1 and transmitted to the industrial control 13. After passing through the code scanning device 9, the envelope is transmitted to the second transmission device 2, and the second transmission device 2 continues to transmit the envelope. When it is transmitted to the weighing device 10, it is lifted by the weighing plane 101, and the weight of the envelope is weighed at the weighing plane 101, and the obtained weight information is transmitted to the industrial control computer 13. The industrial computer 13 removes envelopes that do not meet any of the standards according to the information fed back by the barcode scanning device 9, the weighing device 10 and the card reader. When removing, the industrial computer 13 controls the driving motor 1131 to operate upward, so that the waste notch 111 is exposed, and the discarded envelopes are removed into the storage box 114 through the waste notch 111 under the action of the second transmission device 2; the waste notch 111 is reset after removal. Finally, the second transmission device 2 transmits the envelopes to the receiving device 12.

[0056] In summary, the technical solution of the present invention realizes the integrated operations of opening the envelope seal, filling the envelope, sealing, scanning the code, detecting, and rejecting the envelope, and combines various functional devices into an integrated structure to meet the usage requirements of the logistics industry.
