[0038] Label paper is used to package cigarettes. Typically, for ease of transportation and use, hundreds of label papers are stacked together to form a label paper pile, and a layer of kraft paper is wrapped around the label paper pile.

[0039] In the related art, when a stack of trademark paper is fed into a packaging machine, the kraft paper wrapped around the stack of trademark paper is generally cut and removed manually, and then the stack of trademark paper is fed into the packaging machine. The entire loading process of the stack of trademark paper is time-consuming and labor-intensive. The staff must not only complete the front-end work of removing the kraft paper from the stack of trademark paper, but also take into account the feeding and supply of the stack of trademark paper on the entire production line, which greatly reduces the feeding efficiency of the stack of trademark paper and affects the production efficiency of the packaging machine.

[0040] Based on the above problems, an embodiment of the present application provides an automatic feeding system for trademark paper of a packaging machine. The system is arranged through the coordination of a first conveyor rail, a second conveyor rail, a material transfer assembly, a cutting assembly and a pushing assembly. The first conveyor rail continuously supplies a stack of trademark paper wrapped with kraft paper. The material transfer assembly, the cutting assembly and the pushing assembly cooperate to remove the kraft paper wrapped on the stack of trademark paper. The second conveyor rail correspondingly and continuously transports and feeds the stack of trademark paper from which the kraft paper has been removed, thereby realizing continuous feeding of the stack of trademark paper, effectively improving the feeding efficiency of the stack of trademark paper, and improving the production efficiency of the packaging machine.

[0041] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 An embodiment of the present application provides an automatic feeding system for trademark paper of a packaging machine, which includes a first conveying rail 100, a second conveying rail 400, a material moving assembly 200, a cutting assembly 300 and a pushing assembly 500.

[0042] The first conveying track 100 is used to convey the label paper bundle 92 wrapped with kraft paper 91 to the unloading station R1. The second conveying track 400 is used to convey the label paper bundle 92 with the kraft paper 91 removed to the loading station R2.

[0043] The material transfer assembly 200 is used to absorb the label paper bundle 92 wrapped with kraft paper 91 from the material taking station R1 and transfer it to the unpacking station R3.

[0044] The cutting assembly 300 is used to cut the kraft paper 91 wrapped on the trademark paper stack 92. The material moving assembly 200 is also used to absorb the cut kraft paper 91 on the trademark paper stack 92 and drive the cut kraft paper 91 to be pulled out of the trademark paper stack 92. The material moving assembly 200 can transfer the pulled out kraft paper 91 to the waste station R4.

[0045] The pushing assembly 500 is used to push the label paper bundle 92 from which the kraft paper 91 has been removed at the unpacking station R3 to the second conveying rail 400 .

[0046] It should be noted that, in this application, the first conveyor rail 100 can be a linear or curved rail driven by a belt, chain, roller, or other drive mechanism, without limitation. The retrieving station R1 can be located at the end, middle, or other locations of the first conveyor rail 100, depending on site requirements. The label paper stack 92 wrapped in kraft paper 91 on the first conveyor rail 100 can be loaded by a robot or other mechanism.

[0047] Similarly, the second conveyor rail 400 can be a linear or curved rail driven by a belt, chain, roller, or other drive mechanism, without limitation. The loading station R2 can be located at the end, middle, or other area of the second conveyor rail 400, depending on site requirements. The loading station R2 is connected to the loading port of the packaging machine. The second conveyor rail 400 transports the label paper stack 92, from which the kraft paper 91 has been removed, to the loading station R2, completing the loading of the packaging machine.

[0048] In the present application, the material transfer assembly 200 can be a cooperation structure of a multi-axis manipulator and a vacuum suction cup, or a cooperation structure of a three-axis mobile platform and a cylinder clamp. There is no specific limitation. It can realize the function of sucking or releasing the trademark paper stack 92 and driving the sucked trademark paper stack 92 to transfer in space.

[0049] Furthermore, it should be noted that the material shifting assembly 200 can be moved toward or away from a target workpiece to hold or release the target workpiece. In this embodiment of the present application, when the label paper stack 92 wrapped in kraft paper 91 is in the unpacking station R3, the material shifting assembly 200 can be moved toward the label paper stack 92 wrapped in kraft paper 91, thereby applying a vertical load to the label paper stack 92 wrapped in kraft paper 91, thereby stably securing the label paper stack 92 wrapped in kraft paper 91 in the unpacking station R3.

[0050] In the present application, the cutting assembly 300 can be a structure that combines a multi-axis manipulator and a cutter, with the cutter forming the cutting end of the cutting assembly 300. The multi-axis manipulator drives the cutter to move to the surface of the target workpiece and moves along the surface of the target workpiece in a predetermined direction to cut the target workpiece. Of course, the cutting assembly 300 can also be a structure that combines a screw-nut mechanism and a cutter, and there is no specific limitation. In the embodiment of the cutter of the cutting assembly 300, the cutter can be, but is not limited to, a pull-hook cutter, a scratch cutter, etc.

[0051] In the embodiment of the present application, when the label paper stack 92 wrapped with kraft paper 91 is in the unpacking station R3, the cutting end of the cutting assembly 300 can slide along at least one side of the kraft paper 91, thereby cutting the kraft paper 91 and forming a cutting slit in the kraft paper 91 so that the kraft paper 91 can be removed. At this time, the material transfer assembly 200 can move to the cut kraft paper 91, steadily absorb the cut kraft paper 91, and then extract the cut kraft paper 91 wrapped on the label paper stack 92 by moving relative to the label paper stack 92, and then transfer it to the waste station R4, thereby removing the kraft paper 91 wrapped on the label paper stack 92.

[0052] In the present application, the unpacking station R3 is located between the material removal station R1 and the loading station R2, and the unpacking station R3 can be located adjacent to the second conveyor rail 400. The pushing assembly 500 can be a structure in which a screw nut mechanism cooperates with a pushing member, or a structure in which a gear rack cooperates with a pushing member, without any specific limitation. When the label paper stack 92 is located at the unpacking station R3 and the kraft paper 91 wrapped around the label paper stack 92 is sucked away by the material transfer assembly 200, the pushing assembly 500 can push the label paper stack 92 with the kraft paper 91 removed to the second conveyor rail 400. The second conveyor rail 400 then transports the label paper stack 92 with the kraft paper 91 removed to the loading station R2, completing the loading of the label paper stack 92.

[0053] Through the above description, it is easy to understand that the operating principle of the automatic feeding system of the packaging machine trademark paper implemented in the present application is as follows: the first conveyor rail 100 conveys the trademark paper stack 92 wrapped with kraft paper 91 to the material taking station R1, then the material moving component 200 absorbs the trademark paper stack 92 wrapped with kraft paper 91 at the material taking station R1 and transfers the trademark paper stack 92 wrapped with kraft paper 91 to the unpacking station R3, then the cutting component 300 cuts off the kraft paper 91 wrapped on the trademark paper stack 92 at the unpacking station R3, and then the material moving component 200 absorbs the trademark paper stack 92 wrapped with kraft paper 91 at the material taking station R1 and transfers the trademark paper stack 92 wrapped with kraft paper 91 to the unpacking station R3. The cut kraft paper 91 on the paper stack 92 is pulled away from the label paper stack 92 and then transferred to the waste station R4 for removal. While the material transfer assembly 200 is transferring the cut kraft paper 91 to the waste station R4, the pushing assembly 500 simultaneously pushes the label paper stack 92, from which the kraft paper 91 has been removed, from the unpacking station R3 to the second conveyor rail 400. Finally, the second conveyor rail 400 conveys the label paper stack 92, from which the kraft paper 91 has been removed, to the loading station R2, completing one loading operation. This loading process is cyclical, continuously conveying the label paper stack 92, from which the kraft paper 91 has been removed, to the loading station R2, achieving continuous loading of the label paper stack 91, effectively improving the loading efficiency of the label paper stack 91 and the production efficiency of the packaging machine.

[0054] It is not difficult to understand that the automatic feeding system for trademark paper of the packaging machine of the embodiment of the present application is configured by the coordination of the first conveyor rail 100, the second conveyor rail 400, the material moving assembly 200, the cutting assembly 300 and the pushing assembly 500. The first conveyor rail 100 continuously supplies the trademark paper stack 92 wrapped with kraft paper 91. The material moving assembly 200, the cutting assembly 300 and the pushing assembly 500 cooperate to remove the kraft paper 91 wrapped on the trademark paper stack 92. The second conveyor rail 400 correspondingly and continuously transports the trademark paper stack 92 with the kraft paper 91 removed to the feeding station R2, thereby realizing continuous feeding of the trademark paper stack 91, effectively improving the feeding efficiency of the trademark paper stack 91, and improving the production efficiency of the packaging machine.

[0055] In some embodiments of this application, see Figure 3 and Figure 4 The material transfer assembly 200 can press the trademark paper stack 92 at the unpacking station R3 or detach it from the trademark paper stack 92. The trademark paper stack 92 at the unpacking station R3 has a limited state in which it is pressed by the material transfer assembly 200 and a free state relatively separated from the material transfer assembly 200. The cutting assembly 300 cuts off the kraft paper 91 wrapped on the trademark paper stack 92 when the trademark paper stack 92 is in the limited state. The pushing assembly 500 pushes the trademark paper stack 92 to the second conveying rail 400 when the trademark paper stack 92 is in the free state.

[0056] It should be noted that after the material moving component 200 transfers the trademark paper stack 92 wrapped with kraft paper 91 to the unpacking station R3, the trademark paper stack 92 wrapped with kraft paper 91 is supported on the unpacking station R3. The material moving component 200 does not leave the trademark paper stack 92 first, but maintains contact with the kraft paper 91 wrapped on the trademark paper stack 92 and moves a short distance toward the trademark paper stack 92, so that the material moving component 200 applies a vertical load to the trademark paper stack 92 wrapped with kraft paper 91, so that the material moving component 200 presses and fixes the trademark paper stack 92 wrapped with kraft paper 91 on the unpacking station R3, so that the trademark paper stack 92 wrapped with kraft paper 91 is in a limited state pressed by the material moving component 200.

[0057] In this way, the trademark paper stack 92 is tightly fitted to the kraft paper 91 on the outside, reducing the loosening or displacement of the stacked trademark paper inside the trademark paper stack 92. When the cutting component 300 cuts the kraft paper 91, the cutting end of the cutting component 300 can cut the kraft paper 91 more neatly along the corresponding surface of the kraft paper 91, avoiding the undesirable situation of uneven cutting or cutting rough edges caused by the shaking of the trademark paper stack 92. It can also reduce the probability that the kraft paper 91 pulls the knife to the internal trademark paper when the cutting component 300 cuts the kraft paper 91, causing the edge of the trademark paper stack 92 to curl or break, thereby improving the structural stability of the trademark paper stack 92.

[0058] It is easy to understand that after the cutting component 300 cuts off the kraft paper 91 wrapped around the trademark paper stack 92, the material moving component 200 absorbs the cut kraft paper 91 and moves it in a direction away from the trademark paper stack 92, thereby pulling the cut kraft paper 91 out of the trademark paper stack 92. At this time, the trademark paper stack 92 is in a free state relatively separated from the material moving component 200, and the pushing component 500 can push the trademark paper stack 92 with the kraft paper 91 removed to the second conveying rail 400.

[0059] Further, see Figure 3 and Figure 4 The material transfer assembly 200 includes a first driving member 210 and an adsorption member 220 provided at the output end of the first driving member 210. The first driving member 210 is configured to drive the adsorption member 220 to move in a circular motion along the material taking station R1, the unpacking station R3 and the waste station R4 in sequence.

[0060] Specifically, the first driving member 210 can be, but is not limited to, a structure that can move freely in space, such as a multi-axis mobile platform and a mobile manipulator. The adsorption member 220 can be connected to a vacuum suction cup of a vacuum generator, and an adsorption plane is formed on the adsorption member 220. After the vacuum generator vacuums the adsorption member 220, a negative pressure environment is formed on the adsorption plane, thereby stably sucking the trademark paper stack 92 wrapped with kraft paper 91. When the vacuum generator stops vacuuming the adsorption member 220 and rushes air into the adsorption member 220, the negative pressure on the adsorption plane of the adsorption member 220 disappears, and the adsorption member 220 releases the trademark paper stack 92 wrapped with kraft paper 91.

[0061] It can be understood that when the automatic feeding system for label paper of the packaging machine of the embodiment of the present application is in operation, the first driving member 210 first drives the adsorption member 220 to move to the material taking station R1, so that the adsorption member 220 stably absorbs the label paper stack 92 wrapped with kraft paper 91 at the material taking station R1, and then drives the adsorption member 220 to move to the unpacking station R3, so that the adsorption member 220 releases the label paper stack 92 wrapped with kraft paper 91 at the unpacking station R3. At this time, the adsorption member 220 The first driving member 210 maintains contact with the kraft paper 91 wrapped around the label paper stack 92 but removes the suction force on the kraft paper 91. Then, the first driving member 210 drives the suction member 220 a short distance closer to the label paper stack 92, so that the suction member 220 places the label paper stack 92 wrapped with the kraft paper 91 in a limited state, making the label paper stack 92 compact and enabling the cutting assembly 300 to stably and accurately cut the kraft paper 91, thereby reducing the probability of damage to the label paper stack 92.

[0062] After the cutting assembly 300 cuts off the kraft paper 91 wrapped around the trademark paper stack 92, the suction member 220 maintains contact with the cut kraft paper 91 and absorbs the kraft paper 91. Then, the first driving member 210 drives the suction member 220 to move to the waste station R4, so that the suction member 220 releases the cut kraft paper 91 at the waste station R4, completing the removal of the kraft paper 91.

[0063] It should be noted that when the first driving member 210 drives the adsorption member 220 to move from the unpacking station R3 to the waste station R4, the pushing component 500 simultaneously pushes the trademark paper stack 92 with the kraft paper 91 removed from the unpacking station R3 to the second conveying rail 400, thereby further improving the loading efficiency of the trademark paper stack 92.

[0064] It can be understood that the above-mentioned first driving member 210 drives the adsorption member 220 to move in a cycle along the material picking station R1, the unpacking station R3 and the waste station R4 in sequence, and can automatically and efficiently remove the kraft paper 91 wrapped around the trademark paper stack 92, effectively improving the loading efficiency of the trademark paper stack 92.

[0065] Further, see Figure 3 and Figure 4 The retrieving station R1, the unpacking station R3, and the waste station R4 are sequentially distributed along a first direction X, and there is a height difference between the retrieving station R1 and the unpacking station R3 in a third direction Z perpendicular to the first direction X. The first conveyor rail 100 extends along the first direction X, and the second conveyor rail 400 is parallel to and spaced apart from the first conveyor rail 100 in the third direction Z. The first driving member 210 includes a first driving unit 211 and a second driving unit 212. The first driving unit 211 is configured to drive the adsorption member 220 to move along the first direction X, and the second driving unit 212 is configured to drive the first driving unit 211 to move along the third direction Z.

[0066] Specifically, the automatic label paper feeding system for a packaging machine according to an embodiment of the present application further includes a base frame 800, on which a first conveyor rail 100, a second conveyor rail 400, a material moving assembly 200, a cutting assembly 300, and a pushing assembly 500 are all disposed. The first direction X and the third direction Z are mutually perpendicular linear directions. The first direction X may correspond to the length direction of the base frame 800, and the third direction Z may correspond to the height direction of the base frame 800.

[0067] The first conveyor rail 100 and the second conveyor rail 400 are parallel and spaced apart in the third direction Z, that is, there is a height difference between the first conveyor rail 100 and the second conveyor rail 400. The material picking station R1 and the unpacking station R3 are understood as two supporting planes that can support the trademark paper stack 92. The height difference between the first conveyor rail 100 and the second conveyor rail 400 is equal to the distance between the material picking station R1 and the unpacking station R3 in the third direction Z.

[0068] The first driving unit 211 and the second driving unit 212 can both be configured as linear cylinders or linear motors.

[0069] Along the first direction X, the unpacking station R3 is located between the retrieving station R1 and the scrap station R4. Along the third direction Z, the scrap station R4 is located between the retrieving station R1 and the unpacking station R3. The retrieving station R1 is located at the end of the first conveyor rail 100 near the unpacking station R3. The unpacking station R3 is located on the base frame 800 near the infeed end of the second conveyor rail 400.

[0070] When the automatic label paper feeding system of the packaging machine is running, the first driving unit 211 first drives the adsorption member 220 having the label paper bundle 92 (wrapped with kraft paper 91) sucked thereon to the top of the unpacking station R3 along the first direction X. Then, the second driving unit 212 drives the first driving unit 211 and the adsorption member 220 thereon to move to the unpacking station R3 along the third direction Z, so that the adsorption member 220 places the label paper bundle 92 wrapped with kraft paper 91 thereon at the unpacking station R3. At this time, the adsorption member 220 maintains contact with the label paper bundle 92 wrapped with kraft paper 91 and removes the adsorption force thereon. When the cutting assembly 300 cuts After cutting off the kraft paper 91 wrapped around the trademark paper stack 92, the suction piece 220 maintains contact with the cut kraft paper 91 and absorbs the kraft paper 91. Then, the second driving unit 212 drives the first driving unit 211 and the suction piece 220 thereon to move to the height of the waste station R4 along the third direction Z, thereby extracting the cut kraft paper 91 from the trademark paper stack 92. Then, the first driving unit 211 drives the suction piece 220 with the kraft paper 91 absorbed along the first direction X to the waste station R4, so that the suction piece 220 releases the kraft paper 91 at the waste station R4, completing the removal of the kraft paper 91.

[0071] Through the above description, it is not difficult to understand that, by distributing the material taking station R1, the unpacking station R3 and the waste station R4 in sequence along the first direction X, and forming a height difference between the material taking station R1, the waste station R4 and the unpacking station R3 in the third direction Z, and the material taking station R1, the unpacking station R3 and the waste station R4 are not on the same straight line, it is ensured that the kraft paper 91 will not fall into the unpacking station R3 after being rejected and interfere with the unpacking action of the next trademark paper pile 92. At the same time, the second conveyor rail 400 and the first conveyor rail 100 are coordinated to move along the first conveyor rail 100. The three directions Z are parallel and spaced apart, and the first driving member 210 is provided with a first driving unit 211 that can be driven to move along the first direction X and a second driving unit 212 that can be driven to move along the third direction Z. This can greatly shorten the moving path of the adsorption member 220 that circulates along the material picking station R1, the unpacking station R3 and the waste station R4, reduce the structural cost and occupied space of the entire packaging machine's automatic feeding system for trademark paper, and further improve the feeding efficiency of the trademark paper stack 92, thereby improving the production efficiency of the packaging machine.

[0072] In addition, in order to facilitate the removal of kraft paper 91, see Figure 1 The automatic feeding system of trademark paper of the packaging machine further includes a rejection slide 700 provided at the waste station R4, and the rejection slide 700 is used to guide the kraft paper 91 released by the material transfer component 200 to a preset station.

[0073] Specifically, the rejection chute 700 is constructed as an inclined chute, and a waste box is set at the bottom end of the rejection chute 700. The adsorption part 220 can release the cut kraft paper 91 on the rejection chute 700 of the waste station R4 so that it can be exported to the preset station by the rejection chute 700. The preset station can be a kraft paper recycling station or a kraft paper secondary processing station, which is not specifically limited.

[0074] In some embodiments of this application, see Figure 3 and Figure 4 The automatic loading system for trademark paper of the packaging machine also includes a blanking platform 600 capable of supporting the trademark paper stack 92. The blanking platform 600 itself is surrounded by a blanking channel 610. The opposite ends of the blanking channel 610 are respectively connected to the material taking station R1 and the unpacking station R3. The blanking channel 610 is used to guide and limit at least two adjacent sides of the trademark paper stack 92.

[0075] Specifically, the bottom of the blanking platform 600 forms a supporting surface for supporting the trademark paper stack 92 , which also corresponds to the unpacking station R3 , and is docked with the feeding end of the second conveyor rail 400 .

[0076] It is not difficult to understand that, through the above-mentioned arrangement, after the material transfer component 200 absorbs the trademark paper stack 92 wrapped with kraft paper 91 at the material picking station R1, the trademark paper stack 92 can be kept in a neat and stable state and slid to the unpacking station R3 along the blanking channel 610 defined by the blanking platform 600 under the guiding and limiting effect of the blanking channel 610 on the trademark paper stack 92, thereby stably and accurately transferring the trademark paper stack 92 to the unpacking station R3, avoiding the shaking of the trademark paper stack 92 during the transfer process and causing the subsequent kraft paper 91 to be cut unevenly or with rough edges.

[0077] In addition, the limiting effect of the blanking channel 610 on the side of the trademark paper stack 92 can also cooperate with the material moving component 200 to stably press and fix the trademark paper stack 92 wrapped with kraft paper 91 at the unpacking station R3, further enabling the cutting end of the cutting component 300 to cut the kraft paper 91 more neatly along the corresponding surface of the kraft paper 91, avoiding the undesirable situation of uneven cutting or cutting rough edges caused by the shaking of the trademark paper stack 92, and can also reduce the probability of the kraft paper 91 pulling the knife to the internal trademark paper when the cutting component 300 cuts the kraft paper 91, causing the edge of the trademark paper stack 92 to curl or break, thereby improving the structural stability of the trademark paper stack 92.

[0078] Further, see Figure 4 A bypass opening 620 connected to the blanking channel 610 is formed on the blanking platform 600. The bypass opening 620 allows at least a portion of the kraft paper 91 wrapped in the trademark paper stack 92 to extend out. The cutting end of the cutting assembly 300 is directed toward the bypass opening 620 and can move relative to the bypass opening 620 along the second direction Y to cut the kraft paper 91.

[0079] Specifically, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The avoidance opening 620 is provided on a side of the blanking platform 600 and is opposite to the feeding end of the second conveying rail 400 .

[0080] See also Figure 5 The cutting assembly 300 includes a second driving member 310 disposed on the blanking table 600 and a cutter 320 disposed at the output end of the second driving member 310. The second driving member 310 is configured to drive the cutter 320 to move along the second direction Y. The second driving member 310 can be configured as a rodless cylinder extending along the second direction Y to improve space utilization. The cutter 320 forms the cutting end of the cutting assembly 300.

[0081] Specifically, the cutter 320 may be, but is not limited to, a pulling hook knife, a scoring knife, or the like.

[0082] It can be understood that when the trademark paper stack 92 wrapped with kraft paper 91 is in the unpacking station R3, the kraft paper 91 extends toward the avoidance opening 620 on the side away from the second conveyor rail 400 in the first direction X and the edge contacts the cutter 320. At this time, the second driving member 310 drives the cutter 320 to move along the second direction Y, so that a cutting gap is formed on the kraft paper 91 so that the kraft paper 91 can be pulled out by the material moving assembly 200.

[0083] In some embodiments of this application, see Figure 4 Along the stacking direction of the trademark paper stack 92, at least one side of the trademark paper stack 92 has an exposed portion 921 that is not wrapped by the kraft paper 91. A limit member 80 is provided at the unpacking station R3. The limit member 80 can move relative to the unpacking station R3 to resist or separate from the exposed portion 921 in the direction in which the material transfer assembly 200 withdraws the kraft paper 91.

[0084] Specifically, the kraft paper 91 is annular and wraps around the middle area of the label paper stack 92. Opposite sides of the label paper stack 92 are not covered by the kraft paper 91. That is, opposite sides of the label paper stack 92 have exposed portions 921. Two corresponding stoppers 80 are provided. The two stoppers 80 are disposed on opposite sides of the blanking platform 600 along the second direction Y, correspondingly abutting or disengaging from the exposed portions 921. It should be noted that when the label paper stack 92 wrapped with the kraft paper 91 is at the unpacking station R3, the stoppers 80 are at the same height as the exposed portions 921 of the label paper stack 92.

[0085] The limiting member 80 is rotatably or movably mounted on the blanking platform 600. For example, in one embodiment, the limiting member 80 is rotatably mounted on the blanking platform 600, and a third driving member (not shown) is provided on the blanking platform 600. The output end of the third driving member is connected to the limiting member 80 to drive the limiting member 80 to rotate relative to the blanking platform 600 to engage with or disengage from the exposed portion 921 of the label paper stack 92. The third limiting member may be a rotary driving member such as an electric motor. For another example, the limiting member 80 is movably mounted on the blanking platform 600, and a fourth driving member (not shown) is provided on the blanking platform 600. The fourth driving member is connected to the limiting member 80 to drive the limiting member 80 to extend or retract relative to the blanking platform 600 to engage with or disengage from the exposed portion 921 of the label paper stack 92. The fourth driving member may be a linear driving member such as a linear cylinder or a linear motor.

[0086] In another embodiment, the limiting member 80 is rotatably mounted on the blanking platform 600 via a rotating shaft. An elastic reset member (not shown in the figure) is provided between the limiting member 80 and the blanking platform 600. The elastic reset member can be a torsion spring sleeved on the rotating shaft. The limiting member 80 has a guide slope and a support plane along its own thickness direction. The guide slope is inclined toward the unpacking station R3. When the material transfer assembly 200 transfers the trademark paper stack 92 wrapped with kraft paper 91 from the material taking station R1 to the unpacking station R3, the trademark paper The exposed portion 921 of the label paper stack 92 slides along the guide slope of the stopper 80 and is introduced into the unpacking station R3. Driven by the exposed portion 921 of the label paper stack 92, the stopper 80 rotates relative to the blanking platform 600, thereby clearing the label paper stack 92. When the label paper stack 92 wrapped with kraft paper 91 is transferred to the unpacking station R3, the stopper 80 is elastically reset by the elastic reset member and returns to its initial position. At this point, the abutting surface of the stopper 80 precisely abuts the exposed portion 921 of the label paper stack 92. In this embodiment, a corresponding drive member is not required, reducing structural costs.

[0087] It should be understood that when the material transfer assembly 200 transfers the label paper stack 92 wrapped with kraft paper 91 from the material retrieving station R1 to the unpacking station R3, the limiting member 80 is in a disengaged state, avoiding the label paper stack 92 on the material transfer assembly 200; when the label paper stack 92 wrapped with kraft paper 91 is at the unpacking station R3, the limiting member 80 is in a holding state against the exposed portion 921 of the label paper stack 92. In this way, when the material transfer assembly 200 removes the kraft paper 91 cut by the cutting assembly 300 from the label paper stack 92, the limiting member 80 holds the label paper stack 92 in a position, keeping the label paper stack 92 stable, effectively reducing the risk of the label paper on the label paper stack 92 being carried away by the kraft paper 91, and allowing the kraft paper 91 to be smoothly removed.

[0088] In addition, it should be noted that when the trademark paper stack 92 wrapped with kraft paper 91 is located at the unpacking station R3, the limiting member 80 can also cooperate with the material shifting component 200 to support and limit different parts of the trademark paper stack 92, so that the trademark paper stack 92 wrapped with kraft paper 91 can remain in a compressed state during the cutting process of the kraft paper 91 by the cutting component 300, so that the cutting component 300 can cut the kraft paper 91 more stably and smoothly, and can further avoid the undesirable situation of uneven cutting or cutting rough edges caused by the shaking of the trademark paper stack 92.

[0089] In some embodiments of this application, see Figure 2 and Figure 3 A stopper 110 is provided on the first conveyor rail 100 , and the stopper 110 is used to stop the trademark paper stack 92 wrapped with kraft paper 91 at the material picking station R1 . The stopper 110 is spaced apart relative to the conveying plane of the first conveyor rail 100 .

[0090] Specifically, the material picking station R1 is located at the end of the first conveyor rail 100 close to the material moving assembly 200, and the stopper 110 is arranged on this end. The stopper 110 can be a block or baffle perpendicular to the conveying plane of the first conveyor rail 100, and the stopper 110 does not contact the conveying plane of the first conveyor rail 100, so as to avoid friction obstruction to the normal conveying of the first conveyor rail 100.

[0091] It is easy to understand that when the first conveyor rail 100 conveys the trademark paper stack 92 wrapped with kraft paper 91 to the material picking station R1, the first conveyor rail 100 stops. At this time, the material transfer assembly 200 absorbs the trademark paper stack 92 wrapped with kraft paper 91 from the material picking station R1 and transfers it to the unpacking station R3.

[0092] In some embodiments of this application, see Figure 1 A first detecting member 120 is provided at the end of the first conveyor rail 100 away from the material picking station R1. The first detecting member 120 is configured to detect the number of the brand paper stacks 92 on the first conveyor rail 100. The automatic brand paper feeding system of the packaging machine also includes a feeding mechanism (not shown in the figure). The feeding mechanism is configured to supply the brand paper stacks 92 wrapped with kraft paper 91 to the first conveyor rail 100 based on the detection signal of the first detecting member 120.

[0093] It should be noted that the end of the first conveyor rail 100 away from the retrieving station R1 refers to the feeding end of the first conveyor rail 100, that is, the feeding mechanism delivers the trademark paper stack 92 wrapped with kraft paper 91 to the position of the first conveyor rail 100, and the position of the trademark paper stack 92 on the first conveyor rail 100 that is farthest from the retrieving station R1 refers to the feeding end of the first conveyor rail 100.

[0094] The automatic feeding system of trademark paper of the packaging machine includes a control system, which is communicated with the feeding mechanism, the first detection member 120, the material moving component 200, the cutting component 300 and the pushing component 500 to effectively control the material taking, moving and feeding actions of the entire system.

[0095] The feeding mechanism can be a mobile manipulator, and the first detection component 120 can be a distance sensor, such as a laser distance sensor, an infrared distance sensor, etc. The first detection component 120 detects the distance between the trademark paper stack 92 on the first conveyor rail 100 and the feeding end of the first conveyor rail 100 to determine the number of trademark paper stacks 92 on the first conveyor rail 100. When the first detection component 120 detects that the number of trademark paper stacks 92 on the first conveyor rail 100 is less than a preset value, the control system controls the feeding mechanism to transfer the trademark paper stack 92 wrapped with kraft paper 91 to the first conveyor rail 100 according to the detection signal of the first detection component 120, so as to ensure the continuity of the initial incoming material and improve the feeding efficiency of the trademark paper stack 92 to the packaging machine.

[0096] Of course, the first detecting member 120 may also be a CCD camera, which directly obtains the number of all the trademark paper stacks 92 on the first conveying rail 100 by photographing.

[0097] It should be noted that, since the first conveyor rail 100 is stopped to wait for the material transfer component 200 to absorb the trademark paper stack 92 wrapped with kraft paper 91 from the material picking station R1 and transfer it to the unpacking station R3, and the second conveyor rail 400 is in a conveying state to ensure the continuity of feeding the trademark paper stack 92, there is a gap in the trademark paper stack 92 at the corresponding part of the conveying plane on the second conveyor rail 400, that is, there is no trademark paper stack 92.

[0098] Based on this, in some embodiments of this application, see Figure 1 and Figure 2 The second conveying rail 400 is provided with at least three detection positions (not shown in the figure) spaced apart in sequence along its conveying direction. The distance between two adjacent detection positions is equal to the length or width of the trademark paper stack 92. Each detection position is provided with a second detection member (not shown in the figure). The second detection member is used to detect whether there is a trademark paper stack 92 at the corresponding detection position.

[0099] Specifically, the second detection element can be a photoelectric sensor that directly senses whether the label paper bundle 92 is present at the corresponding detection position. With this arrangement, during the dynamic conveying process of the second conveyor rail 400, if any of the detection elements detects that the label paper bundle 92 is absent at the corresponding detection position, indicating that there is a gap in the label paper bundle 92 at the corresponding position on the second conveyor rail 400, the control system can then control the entire packaging machine's automatic label paper feeding system to initiate a feeding cycle, ensuring continuous feeding of the label paper bundle 92.

[0100] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0101] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
