Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a packaging equipment for articles. Background Technology

[0002] In automated packaging operations, one workflow involves placing the items to be packaged into open boxes, then labeling and laminating the boxes to complete the packaging. Existing technologies typically employ automated production line systems with multiple interconnected devices, using robotic arms or conveyor belts to transfer boxes between labeling stations, packaging stations, and other adjacent stations. However, this approach has the following shortcomings:

[0003] The intermittent start-stop operation of conveyor belts (starting to transport packaging boxes to the secondary packaging station, then pausing to perform secondary packaging operations) can easily lead to abnormally reduced spacing between adjacent packaging boxes due to inertial displacement or external interference. This abnormal spacing can cause packaging boxes to stack or over-enter the secondary packaging station, resulting in an increased packaging failure rate and decreased work efficiency. Furthermore, robotic arms can complicate the equipment structure. Utility Model Content

[0050] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0051] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0052] In some embodiments, such as Figures 1-2 As shown, this utility model proposes a packaging device for articles, comprising:

[0053] A film-coating mechanism 10 is used to film and package a box 70 containing items.

[0054] The first conveying mechanism 20 is located below the film coating mechanism 10. The first conveying mechanism 20 has a second conveying mechanism 50 and a third conveying mechanism 80 at its beginning and end, respectively. The three are arranged in a relay conveying relationship along the conveying direction.

[0055] A lifting mechanism 30 is located below the first conveying mechanism 20; the lifting mechanism 30 is used to drive the packaging box 70 on the first conveying mechanism 20 to move up and down toward the film coating mechanism 10.

[0056] The first conveying mechanism 20 is provided with a first blocking structure 40 at its end. The first blocking structure 40 moves up and down in the vertical direction to limit or release the packaging box 70 flowing out of the first conveying mechanism 20.

[0057] The second conveying mechanism 50 is provided with a second blocking structure 60 at its end. The second blocking structure 60 moves up and down in the vertical direction to limit or release the packaging box 70 flowing into the first conveying mechanism 20.

[0058] It should be noted that the preferred item in this embodiment is a blood bag, and filling the blood bag with plasma or red blood cells constitutes the primary packaging of the item. The area below the first conveying mechanism 20 corresponds to the side of the first conveying mechanism 20 furthest from the coating mechanism 10, and the first conveying mechanism 20 can only accept one packaging box 70 containing an item at a time. The second conveying mechanism 50 is also equipped with a labeling mechanism 90 for labeling the packaging boxes 70 on the second conveying mechanism 50. The second conveying mechanism 50 then sends the correctly labeled packaging boxes 70 back to the first conveying mechanism 20 so that the coating mechanism 10 can perform secondary packaging. The first conveying mechanism 20 in this embodiment corresponds to a secondary packaging station.

[0059] The third conveying mechanism 80 is equivalent to the unloading mechanism; and a first transition zone without mechanical connection is formed between the end of the second conveying mechanism 50 and the beginning of the first conveying mechanism 20. The horizontal distance D1 of the first transition zone satisfies: 0≤D1≤0.2 times the minimum length of the packaging box 70; a second transition zone without mechanical connection is formed between the end of the first conveying mechanism 20 and the beginning of the third conveying mechanism 80. The horizontal distance D2 of the second transition zone satisfies: 0≤D2≤0.2 times the minimum length of the packaging box 70.

[0060] Furthermore, the conveying planes of the first conveying mechanism 20, the second conveying mechanism 50, and the third conveying mechanism 80 are coplanar, with a height difference ΔH ≤ 1mm between adjacent conveyors. This ensures that when the packaging box 70 is conveyed from the second conveying mechanism 50 to the first conveying mechanism 20 and from the first conveying mechanism 20 to the third conveying mechanism 80, the bottom surface of the packaging box 70 simultaneously remains in contact with the conveying planes of the two adjacent conveying mechanisms, achieving a smooth transition without power interruption. A robotic arm can also be installed between the first conveying mechanism 20 and the second conveying mechanism 50, and between the first conveying mechanism 20 and the third conveying mechanism 80, for auxiliary handling; this is not limited here.

[0061] Thus, when the packaging equipment is started, the control unit of the packaging equipment activates the first conveying mechanism 20 and the second conveying mechanism 50. The second conveying mechanism 50 sends a packaging box 70 containing an item into the first conveying mechanism 20. Then, the control unit activates the second blocking structure 60 to prevent subsequent packaging boxes 70 from being sent into the first conveying mechanism 20. The control unit also activates the first blocking structure 40 to prevent the packaging box 70 from flowing out of the first conveying mechanism 20. Then, the control unit closes the first conveying mechanism 20 and the second conveying mechanism 50. Then, the control unit activates the lifting mechanism 30, which can drive the packaging box 70 on the first conveying mechanism 20 to rise to the film-coating mechanism 10, so that the distance between the open plane of the packaging box 70 and the bottom of the film-coating mechanism 10 is at a preset distance. Then, the film-coating mechanism 10 performs a second film coating on the packaging box 70.

[0062] After packaging is completed, the control unit controls the lifting mechanism 30 to lower the film-packaged box 70 to the conveying plane of the first conveying mechanism 20. It is necessary to ensure that the lifting mechanism 30 is completely below the first conveying mechanism 20 to avoid affecting the operation of the first conveying mechanism 20. Then, the control unit controls the first blocking structure 40 and the second blocking structure 60 to lower below the corresponding conveying structure, so that the film-packaged box 70 flows from the first conveying mechanism 20 into the third conveying mechanism 80. At the same time, the next film-packaged box 70 flows from the second conveying mechanism 50 into the first conveying mechanism 20. Then, the control unit controls the first blocking structure 40 and the second blocking structure 60 to rise above the corresponding conveying structure, thereby forming a cyclic packaging.

[0063] Therefore, this utility model uses the lifting mechanism 30, the first blocking structure 40 and the second blocking structure 60 to limit and block the packaging box 70 during the conveying process, so as to avoid the abnormal reduction of the distance between adjacent packaging boxes 70 due to inertial displacement or external interference, which would cause the packaging boxes 70 to stack or enter the first conveying mechanism 20 in excess. This not only simplifies the equipment structure, but also improves the success rate of film packaging and the working efficiency of the equipment. Moreover, the lifting mechanism 30 simplifies the equipment structure.

[0064] In some embodiments, such as Figure 1 As shown, the film coating mechanism 10 includes a feeding device 101, a heat sealing device 102, and a receiving device 103;

[0065] The heat sealing device 102 is provided with a heat sealing lower mold 1021 at the bottom. The working surface of the heat sealing lower mold 1021 will be used to heat press the film onto the upper surface of the packaging box 70. The heat sealing lower mold 1021 is used to heat seal the film and cut its edges.

[0066] The heat sealing device 102 is provided with a feeding device 101 and a receiving device 103 at both ends along the conveying direction, and the film of the feeding device 101 is wound onto the receiving device 103 after passing horizontally through the working surface of the heat sealing lower mold 1021.

[0067] The lifting device 303 is used to lift the corresponding packaging box 70, so that the opening of the packaging box 70 forms a surface contact with the film, and the film continues to rise so that the film contacts the heat sealing lower mold 1021 of the heat sealing device 102.

[0068] It should be noted that the working surface of the heat-sealing lower mold 1021 is equipped with a heating element (not shown, same throughout) and an annular cutting blade (not shown, same throughout); the heating element is used to heat the working surface of the heat-sealing lower mold 1021; the annular area formed by the annular cutting assembly exactly matches the edge of the opening of the packaging box 70, so that the annular cutting assembly cuts the film corresponding to the edge of the opening of the packaging box 70. Furthermore, the working surface of the heat-sealing lower mold 1021 is parallel to the opening plane of the packaging box 70.

[0069] The feeding device 101 includes a first rotary motor 1011 and a first drum 1012 connected to the rotating end of the first rotary motor 1011; the receiving device 103 includes a second rotary motor 1031 and a second drum 1032 connected to the rotating end of the second rotary motor 1031. The first rotary motor 1011, the second rotary motor 1031, and the heat sealing device 102 are all fixedly connected to the base of the packaging equipment via corresponding connectors.

[0070] Thus, when the lifting mechanism 30 can drive the packaging box 70 on the first conveying mechanism 20 to rise towards the heat-sealing lower mold 1021, so that the open plane of the packaging box 70 forms surface contact with the film, and then the packaging box 70 continues to rise, so that the open plane of the packaging box 70, the film, and the heat-sealing lower mold 1021 of the heat-sealing device 102 all form surface contact. Then, the heat-sealing lower mold 1021 uses a heating element to heat-seal the film onto the open of the packaging box 70. Then, the film after heat sealing is cut by a ring-shaped cutting blade, thereby completing the film-coated packaging of the packaging box 70. Then, the lifting mechanism 30 drives the film-coated packaging... After the packaged box 70 is lowered to the conveying plane of the first conveying mechanism 20, the control unit simultaneously starts the first rotary motor 1011 and the second rotary motor 1031. The first rotary motor 1011 drives the first roll 1012 to rotate clockwise, conveying the new film stored on the first roll 1012 to the working surface of the heat-sealing lower mold 1021. At the same time, the second rotary motor 1031 drives the second roll 1032 to rotate clockwise, winding the cut residual film onto the second roll 1032, thus cooperating with the first roll 1012 to place the new film flat under the working surface of the heat-sealing lower mold 1021. Meanwhile, the control unit discharges the packaged box 70 after film coating from the first conveying mechanism 20. Thus, the entire process of secondary packaging of the item is completed.

[0071] In some embodiments, such as Figure 1 As shown, the lifting mechanism 30 includes:

[0072] A base 301 is recessed inward to form a hollow cavity 302, the opening size of which matches the packaging box 70; a first conveying mechanism 20 is provided above the opening of the hollow cavity 302, and the projection of the first conveying mechanism 20 in the vertical direction falls completely within the horizontal boundary range of the hollow cavity 302 (that is, when viewed along a direction perpendicular to the upper surface of the base 301, the maximum outer contour of all moving and fixed parts of the first conveying mechanism 20 is located within the spatial envelope defined by the inner wall of the hollow cavity 302).

[0073] The lifting device 303 has its output end connected to the base 301. When the lifting device 303 drives the base 301 to rise vertically to directly below the film covering mechanism 10, the top of the hollow cavity 302 matches and supports the packaging box 70 and rises.

[0074] It should be noted that the top edge of the packaging box 70 extends outward in the circumferential direction to form a flange 701. When the lifting device 303 drives the base 301 to rise, the packaging box 70 will enter the hollow cavity 302 until the flange 701 of the packaging box 70 matches and abuts against the top of the hollow cavity 302 to form a surface contact support state. At this point, the base 301 can drive the corresponding packaging box 70 to rise together. The lifting device 303 proposed in this embodiment is preferably a lifting motor, and the lifting device 303 is installed on the base of the product packaging equipment.

[0075] It is understandable that the base of the packaging equipment is provided with a support rod corresponding to the first conveying mechanism 20. The support rod passes through the base 301 and is then connected to the first conveying mechanism 20 to support the first conveying mechanism 20. The support rod does not affect the lifting and lowering movement of the base 301.

[0076] Thus, when the control unit activates the first conveying mechanism 20 and the second conveying mechanism 50, the second conveying mechanism 50 will send a package 70 containing an item into the first conveying mechanism 20. Then, the control unit activates the second blocking structure 60 to prevent subsequent packages 70 from being sent into the first conveying mechanism 20, and the control unit also activates the first blocking structure 40 to prevent packages 70 from flowing out of the first conveying mechanism 20. Then, the control unit closes the first conveying mechanism 20 and the second conveying mechanism 50, and then activates the lifting device 303. The lifting device 303 drives the base 301 to rise vertically. Because the vertical projection of the first conveying mechanism 20 falls completely within the horizontal boundary of the hollow cavity 302, the first conveying mechanism 20 can remain stationary, and only the base 301 moves upward. Then, the package 70 on the first conveying mechanism 20 will enter the hollow cavity 302 (at this time, the entire first conveying mechanism 20 is inside the hollow cavity 302, such as...). Figure 2 As shown, when the flange 701 of the packaging box 70 matches and abuts against the top of the hollow cavity 302 to form a surface contact support state, the base 301 can drive the corresponding packaging box 70 to rise together to the heat sealing lower mold 1021 so that the opening of the packaging box 70 forms a surface contact with the film. Then the packaging box 70 continues to rise so that the opening plane of the packaging box 70, the film and the heat sealing lower mold 1021 of the heat sealing device 102 all form a surface contact. Then heat sealing and cutting are performed to complete the film packaging of the packaging box 70. Then the control unit controls the lifting device 303 to drive the film-packaged packaging box 70 down to the conveying plane of the first conveying mechanism 20, and then the film-packaged packaging box 70 flows out of the first conveying mechanism 20.

[0077] In some embodiments, to ensure that unwrapped packaging boxes 70 do not overflow from the first conveying mechanism 20, and also to ensure that packaging boxes 70 on the second conveying mechanism 50 do not stack or flow excessively into the first conveying mechanism 20, such as... Figure 1 and Figure 3 As shown, this embodiment proposes the positional relationship between the first type of first blocking structure 40 and the first type of second blocking structure 60:

[0078] The first blocking structure 40 includes a first blocking plate 401 and a first driving device 402;

[0079] The first conveying mechanism 20 includes a first conveyor belt 201. A first baffle plate 401 is provided between the end of the first conveyor belt 201 and the inner wall of the corresponding hollow cavity 302. The bottom of the first baffle plate 401 is connected to the output end of the first driving device 402. The first driving device 402 is connected to the first frame of the first conveying mechanism 20.

[0080] The second blocking structure 60 includes a second blocking plate 601 and a second driving device 602;

[0081] The second conveying mechanism 50 includes a second conveyor belt 501. A second baffle plate 601 is provided between the end of the second conveyor belt 501 and the outer wall of the corresponding hollow cavity 302. The bottom of the second baffle plate 601 is connected to the output end of the second driving device 602. The second driving device 602 is connected to the second frame of the second conveying mechanism 50.

[0082] In other embodiments, to ensure that unwrapped packaging boxes 70 do not leak out of the first conveying mechanism 20, such as... Figure 4 As shown, this embodiment proposes a second positional relationship for the first blocking structure 40:

[0083] The first blocking structure 40 includes a first blocking plate 401 and a first driving device 402;

[0084] The first conveying mechanism 20 includes a first conveyor belt 201, and the first conveyor belt 201 is provided with a plurality of strip-shaped first gaps 202 along its width direction. The length direction of any first gap 202 is parallel to the conveying direction of the first conveyor belt 201.

[0085] A first baffle plate 401 is installed in the first gap 202 at the end of the first conveyor belt 201. The bottom of the first baffle plate 401 is connected to the output end of the first drive device 402. The first drive device 402 is connected to the first frame of the first conveying mechanism 20. The first frame is connected to the support rod.

[0086] It is understood that this embodiment is illustrated by the example of first blocking plates 401 being installed in each of the first gaps 202; wherein each first blocking plate 401 can be connected to a first driving device 402, or all first blocking plates 401 can be connected to the same first driving device 402, which is not limited here.

[0087] To ensure that the packaging boxes 70 on the second conveyor 50 do not stack or flow excessively into the first conveyor belt 201, such as Figure 4 As shown, this embodiment proposes a second type of positional relationship for the second blocking structure 60:

[0088] The second blocking structure 60 includes a second blocking plate 601 and a second driving device 602;

[0089] The second conveying mechanism 50 includes a second conveyor belt 501, and the second conveyor belt 501 is provided with a plurality of strip-shaped second gaps 502 along its width direction, and the length direction of any second gap 502 is parallel to the conveying direction of the second conveyor belt 501.

[0090] A second baffle plate 601 is installed in the second gap 502 at the end of the second conveyor belt 501. The bottom of the second baffle plate 601 is connected to the output end of the second drive device 602. The second drive device 602 is connected to the second frame of the second conveying mechanism 50. The second frame is correspondingly connected to the base of the item packaging equipment.

[0091] It is understood that this embodiment is illustrated by the example of a second baffle plate 601 being installed in each of the second gaps 502; wherein each second baffle plate 601 can be connected to a second driving device 602, or all the second baffle plates 601 can be connected to the same second driving device 602, which is not limited here.

[0092] It should be noted that both the first driving device 402 and the second driving device 602 proposed in this embodiment are preferably drive motors. The first gap 202 extends through the entire effective working length of the first conveyor belt 201, and the cross-section of the first gap 202 is rectangular, with its depth being the same as the thickness of the first conveyor belt 201; the second gap 502 extends through the entire effective working length of the second conveyor belt 501, and the cross-section of the second gap 502 is rectangular, with its depth being the same as the thickness of the second conveyor belt 501.

[0093] Thus, when the control unit controls the first conveyor belt 201 and the second conveyor belt 501 to rotate cyclically, the second conveyor belt 501 will send a package 70 containing an item into the first conveyor belt 201. Then, the control unit activates the second drive device 602, which drives the second baffle 601 to rise from the corresponding second gap 502 to above the conveying plane of the second conveyor belt 501, thereby preventing subsequent packages 70 from being sent into the first conveyor belt 201. The control unit also activates the first drive device 402, which drives the first baffle... Plate 401 rises from the corresponding first gap 202 to above the conveying plane of the first conveyor belt 201, thereby preventing unwrapped packaging boxes 70 from flowing out of the first conveyor belt 201. Then, the control unit controls the first conveyor belt 201 and the second conveyor belt 501 to stop rotating. The control unit then activates the lifting device 303, which drives the base 301 to rise vertically until the flange 701 of the packaging box 70 matches and abuts against the top of the hollow cavity 302, forming a surface contact support state. At this point, the base 301 can drive the corresponding packaging box 70 to move together towards the heat-sealing mold. 1021 rises to make the opening of the packaging box 70 form surface contact with the film. Then, the packaging box 70 continues to rise so that the opening plane of the packaging box 70, the film, and the heat-sealing lower mold 1021 of the heat-sealing device 102 all form surface contact. Then, heat sealing and cutting are performed to complete the film packaging of the packaging box 70. Then, the control unit controls the lifting device 303 to drive the film-packaged packaging box 70 down to the conveying plane of the first conveyor belt 201. Then, the control unit controls the first driving device 402 to drive the first baffle plate 401 down from the corresponding first gap 202 to the first conveyor belt 201. Below 01, to avoid affecting the subsequent rotation of the first conveyor belt 201; the control unit also controls the second drive device 602 to drive the second baffle 601 to descend from the corresponding second gap 502 to below the second conveyor belt 501, to avoid affecting the subsequent rotation of the second conveyor belt 501; thus, the packaged box 70 after film packaging flows out of the first conveyor belt 201, and at the same time, the next packaged box 70 to be film packaged flows into the first conveyor belt 201 from the second conveyor belt 501, and then controls the first baffle 401 and the second baffle 601 to rise above the corresponding conveying mechanism, thereby forming a circular packaging.

[0094] Of course, the positional relationship between the first blocking structure 40 and the second blocking structure 60 can also include the following:

[0095] Firstly, the first conveyor belt 201 has multiple strip-shaped first gaps 202 along its width direction. A first baffle plate 401 is installed in the first gap 202 at the end of the first conveyor belt 201. The bottom of the first baffle plate 401 is connected to the output end of the first drive device 402. A second baffle plate 601 is provided between the end of the second conveyor belt 501 and the outer wall of the corresponding hollow cavity 302. The bottom of the second baffle plate 601 is connected to the output end of the second drive device 602.

[0096] Secondly, a first baffle plate 401 is provided between the end of the first conveyor belt 201 and the inner wall of the corresponding hollow cavity 302, and the bottom of the first baffle plate 401 is connected to the output end of the first drive device 402; the second conveyor belt 501 is provided with a plurality of strip-shaped second gaps 502 along its width direction, and a second baffle plate 601 is matched and installed in the second gap 502 at the end of the second conveyor belt 501, and the bottom of the second baffle plate 601 is connected to the output end of the second drive device 602.

[0097] Therefore, the positional relationship between the first blocking structure 40 and the second blocking structure 60 proposed in this embodiment can be set to any one of the above four types according to the actual situation, and is not limited here.

[0098] In some embodiments, to ensure that the packaging box 70 does not fall off the first conveyor belt 201 during transport, such as... Figure 1 As shown, the first conveyor belt 201 has first outer baffles 203 on both sides along its width direction.

[0099] In some embodiments, to ensure that the packaging box 70 does not fall off the second conveyor belt 501 during transport, such as Figure 1 As shown, the second conveyor belt 501 is provided with second outer baffles 503 on both sides along its width direction.

[0100] In some embodiments, such as Figure 5 As shown, the item packaging equipment also includes a loading station 100, which can place the original items into the packaging box 70 by manual labor, robotic arms or other transportation equipment, and then transport the packaging box 70 containing the original items to the beginning of the second conveying mechanism 50 (equivalent to the loading end of the second conveying mechanism 50).

[0101] The labeling mechanism 90 is located above the second conveying mechanism 50, and includes a barcode reader 901, a labeling device 902, a detection device 903, and a discharge device 904 arranged sequentially along the conveying direction of the second conveying mechanism 50. The barcode reader 901 is used to read the barcode information on the original item, the labeling device 902 is used to print the label and affix it to the packaging box 70, the detection device 903 is used to verify the label information, and the discharge device 904 is used to remove the packaging box 70 containing the defective item from the second conveying mechanism 50.

[0102] Specifically, the control unit activates the second conveyor belt 501, causing it to rotate cyclically. This allows the packaged box 70 containing the items, located at the beginning of the second conveyor belt 501, to sequentially pass through the barcode reader 901, labeling device 902, and detection device 903. The barcode reader 901 reads the barcode information from the original item and then transmits the read barcode information to the labeling device 902. The labeling device 902 prints a label based on the received barcode information and affixes it to the packaged box 70. Finally, the detection device 903 reads the label affixed to the packaged box 70 to determine whether it is a qualified product. If the package is deemed unqualified, the detection device 903 will send a push signal to the discharge device 904. When the unqualified package 70 reaches the position of the discharge device 904, the discharge device 904 will push the unqualified package 70 out of the side of the second conveyor belt 501. If the package is deemed qualified, the detection device 903 will not send a signal to the discharge device 904. The qualified package 70 will be conveyed to the end of the second conveyor belt 501 and then conveyed to the first conveyor belt 201 for secondary film packaging. After the film packaging is completed, it will be sent to the third conveyor mechanism 80 to complete the labeling and secondary packaging operations of the product packaging equipment.

[0103] Specifically, the discharge device 904 includes a drive assembly 9041, a push plate 9042, and a detection sensor (not shown, same throughout).

[0104] The push drive assembly 9041 is located on one side of the end of the second conveyor belt 501. A push plate 9042 is connected to the push end of the push drive assembly 9041. A detection sensor is located on the side of the push plate 9042 facing away from the push drive assembly 9041. The detection sensor is used to detect whether a packaged box 70 has passed by. Thus, when the detection device 903 sends a push electrical signal to the discharge device 904, the control unit simultaneously activates the detection sensor. If a packaged box 70 is detected passing by the push drive assembly 9041, a detection signal is sent to the control unit. At this time, the control unit activates the push drive assembly 9041 based on the push electrical signal and the detection signal, causing the push drive assembly 9041 to drive the push plate 9042 to promptly push the packaged box 70 out of the side of the second conveyor belt 501, preventing unqualified products from reaching subsequent secondary packaging operations.
