[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of this application.

[0045] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0046] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0047] In the description of the present application, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present application.

[0048] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0049] Figure 1-Figure 16 The structure and working process of the box sheet supply system and its cutting device in the present application are shown exemplarily. It should be noted that: Figure 1-Figure 10 Only the cutting device is briefly shown, and the specific structure of the cutting device is not shown. Figure 11-Figure 16 Further shown in .

[0050] The carton sheet supply system 10 is used to supply carton sheets 42 to a packaging machine (not shown, such as a GDX6 packaging machine), so that the packaging machine uses the carton sheets 42 to package contents such as cigarettes.

[0051] To improve the efficiency of cassette supply, see Figure 1 and Figure 2 , the box sheet supply system 10 generally supplies box sheets 42 to the packaging machine in stacks, that is, usually, a plurality of box sheets 42 are stacked to form a box sheet stack 43, and the box sheet supply system 10 supplies the box sheet stack 43 to the packaging machine. In order to prevent the box sheet stack 43 from dispersing in the early process, the outside of the box sheet stack 43 is generally wrapped with wrapping paper 41 (such as kraft paper). The wrapping paper 41 and the box sheet stack 43 together form a box sheet stack 4. It can be seen that the box sheet stack 4 includes wrapping paper 41 and a box sheet stack 43. The box sheet stack 43 includes a plurality of stacked box sheets 42. The wrapping paper 41 is wrapped around the outside of the box sheet stack 43 to package the box sheet stack 43. Specifically, as Figure 2 As shown, the wrapping paper 41 is usually wrapped around multiple surfaces (such as the top surface, the bottom surface and two side surfaces) of the box stack 43 to prevent the boxes 42 in the box stack 43 from spreading out.

[0052] In the case where the box sheet stack 4 includes a box sheet pile 43 and wrapping paper 41, in order to facilitate the taking of the box sheets 42 during the packaging process, the wrapping paper 41 is usually removed before the box sheet stack 4 is conveyed to the packaging machine, so that the box sheet stack 4 without the wrapping paper 41 is conveyed to the packaging machine, that is, only the box sheet pile 43 is conveyed, and the wrapping paper 41 is not included.

[0053] To implement the corresponding wrapping paper removal function, see Figure 1-Figure 16The box sheet supply system 10 includes a cutting device 400. The cutting device 400 is used to cut the wrapping paper 41 wrapped around the stacked box sheets 42 (i.e., the box sheet stack 43) of the box sheet stack 4, so as to disconnect the wrapping paper 41, facilitate the separation of the wrapping paper 41 from the box sheet stack 43, and then enable the box sheet stack 43 to flow toward the packaging machine alone, so as to facilitate the packaging machine to take each box sheet 42 in the box sheet stack 43.

[0054] In the related art, the cutting device 400 directly cuts the wrapping paper 41 wrapped on the box sheet stack 43. In this case, during the cutting process, the wrapping paper 41 is attached to the box sheet stack 43, and the cutting device 400 is likely to cut the box sheet 42, causing damage to the box sheet 42. The damage to the box sheet 42 may, on the one hand, affect the smooth progress of the subsequent packaging process and reduce the packaging efficiency. On the other hand, if the damaged box sheet 42 is used to package cigarettes and other contents, it will also affect the packaging quality and cause quality defects in the finished product.

[0055] In view of the above situation, in order to improve packaging quality and packaging efficiency, the present application improves the structure of the cutting device 400.

[0056] Figure 10-Figure 16 The structure and working process of the cutting device 400 of the present application are exemplarily shown.

[0057] See also Figure 10-Figure 16 In the present application, the cutting device 400 includes a cutting knife 401, a knife seat 402 and a separating mechanism 403. The cutting knife 401 is arranged on the knife seat 402, and is used to cut the wrapping paper 41 wrapped around the stacked box sheets 42 of the box sheet stack 4. The separating mechanism 403 is arranged on the knife seat 402, and is used to exert an action on the wrapping paper 41 during the process of the cutting knife 401 cutting the wrapping paper 41, so that the part of the wrapping paper 41 located between the cutting knife 401 and the stacked box sheets 42 (i.e., the box sheet stack 43) is away from the stacked box sheets 42 (i.e., the box sheet stack 43).

[0058] The cutting device 400 in the related art, although also includes a cutting knife 401 and a knife holder 402, does not include a separation mechanism 403. Therefore, during the cutting process, the wrapping paper 41 is still wrapped around the box sheet stack 43, and the two are almost fitted together without any gap. In this case, when the cutting knife 401 cuts the wrapping paper 41, it is very easy to mistakenly cut the box sheet stack 43, causing damage to the box sheet 42 in the box sheet stack 43, affecting the packaging quality and packaging efficiency.

[0059] In the present application, by adding a separation mechanism 403, during the cutting process, the portion of the wrapping paper 41 between the cutting blade 401 and the box sheet stack 43 (i.e., the portion of the wrapping paper 41 to be cut) is kept away from the box sheet stack 43. Fig.15During the cutting process, the part of the wrapping paper 41 to be cut is pulled away from the box sheet stack 43, and there is a certain gap between the part and the box sheet stack 43. In this way, the cutting knife 401 can easily cut the wrapping paper 41 without touching the box sheet stack 43. Not only is the cutting efficiency higher and the cutting success rate greater, but the risk of miscutting the box sheet stack 43 and damaging the box sheet 42 can also be effectively reduced. Therefore, it is beneficial to improve packaging efficiency and packaging quality.

[0060] It can be seen that by providing the separation mechanism 403, the risk of the cutting device 400 mistakenly cutting the box sheet 42 can be reduced, thereby effectively improving the packaging efficiency and packaging quality.

[0061] The separation mechanism 403 may use a method such as pulling, grabbing or adsorption to move the portion of the wrapping paper 41 between the cutting knife 401 and the stacked box sheets 42 away from the stacked box sheets 42 .

[0062] For example, in some embodiments, the separation mechanism 403 includes a gripping mechanism (not shown, such as a robot arm), which grips the wrapping paper 41 to move the portion of the wrapping paper 41 between the cutting knife 401 and the stacked box sheets 42 away from the stacked box sheets 42 .

[0063] For example, see Figure 10-Figure 16 In some other embodiments, the separation mechanism 403 includes an adsorption mechanism 404, and the adsorption mechanism 404 adsorbs the wrapping paper 41 to keep the portion of the wrapping paper 41 between the cutting knife 401 and the stacked box sheets 42 away from the stacked box sheets 42.

[0064] The adsorption mechanism 404 is used to adsorb the packaging paper 41, which is convenient and hygienic, and is not easy to damage the packaging paper 41 and the box sheet stack 43, which is conducive to further improving the packaging quality and packaging efficiency.

[0065] The adsorption mechanism 404 can adsorb the packaging paper 41 through the separation suction cup 405. The number of the separation suction cup 405 can be one, two or more, that is, the adsorption mechanism 404 can include at least one separation suction cup 405. When the adsorption mechanism 404 includes at least two separation suction cups 405, see Figure 10-Figure 16 The at least two separation suction cups 405 can be arranged at intervals to adsorb different parts of the wrapping paper 41 to improve the adsorption reliability, so that during the cutting process, the adsorption mechanism 404 can stably and reliably adsorb the wrapping paper 41 away from the box stack 43, thereby facilitating the cutting knife 401 to efficiently cut the wrapping paper 41 without damaging the box stack 43.

[0066] In addition, in order to make the wrapping paper 41 be more stably maintained at a position away from the box sheet stack 43 during the cutting process, see Figure 10-Figure 16In some embodiments, the cutting device 400 includes not only a separation mechanism 403, but also a holding mechanism 406. The holding mechanism 406 is used to hold the wrapping paper 41 when the separation mechanism 403 acts on the wrapping paper 41, so that the portion of the wrapping paper 41 located between the cutting knife 401 and the stacked box sheets 42 is maintained at a position away from the stacked box sheets 42.

[0067] By further providing a holding mechanism 406 on the basis of providing a separation mechanism 403 to hold the wrapping paper 41 separated by the separation mechanism 403, the wrapping paper 41 can be effectively prevented from accidentally returning to its original position after being separated by the separation mechanism 403, thereby effectively improving the reliability of the wrapping paper 41 in the separated position, so that the portion of the wrapping paper 41 located between the cutting knife 401 and the stacked box sheets 42 can be more stably maintained in a position away from the stacked box sheets 42, thus making it more convenient for the cutting knife 401 to efficiently cut the wrapping paper 41 without damaging the box sheet stack 43, thereby being more conducive to improving packaging efficiency and packaging quality.

[0068] The holding mechanism 406 can hold the packaging paper 41 by grasping, pulling, pressing or blocking. Figure 10-Figure 16 The holding mechanism 406 includes a telescopic cylinder 407 (such as an air cylinder or an oil cylinder). One of the cylinder rod 408 and the cylinder barrel 409 of the telescopic cylinder 407 is arranged on the knife seat 402, and the other is used to extend between the wrapping paper 41 and the stacked box sheets 42 to hold the wrapping paper 41 during the process of the separation mechanism 403 acting on the wrapping paper 41. At this time, the holding mechanism 406 blocks the part of the wrapping paper 41 located between the cutting knife 401 and the stacked box sheets 42 by telescoping one of the cylinder rod 408 and the cylinder barrel 409 of the telescopic cylinder 407, so as to hold the wrapping paper 41. It is simple and convenient, and the telescopic cylinder 407 is telescopic, which can flexibly meet the requirements of the two different situations of not needing to hold the wrapping paper and needing to hold the wrapping paper. Specifically, the telescopic cylinder 407 is extended only when the wrapping paper 41 needs to be held, and the telescopic cylinder 407 is retracted when the wrapping paper 41 does not need to be held, so as to avoid it, and does not affect the normal progress of other processes.

[0069] In the above embodiment with the holding mechanism 406, in order to prevent the holding mechanism 406 from affecting the cutting process, see Fig.15 In some embodiments, when holding the wrapping paper 41, the portion of the holding mechanism 406 that is used to contact the wrapping paper 41 is located below the cutting blade 401 and above the separating mechanism 403. Fig.15 During the cutting process, the cutting knife 401 is located above the holding mechanism 406, and the separation mechanism 403 is located below the holding mechanism 406. Neither of them interferes with the holding mechanism 406, and the cutting and adsorption can be performed normally respectively, so the efficiency is higher.

[0070] Next, combine Figure 1-Figure 16 The embodiments shown are used to further illustrate the present application.

[0071] like Figure 1-Figure 16 As shown, in this embodiment, the box supply system 10 includes a handling device 100 , a loading device 200 , a feeding mechanism 300 , a cutting device 400 and a recovery device 500 .

[0072] The loading device 200 is used to store the box stack 4 to be transported. Figure 1 As shown, in this embodiment, the loading device 200 is constructed to be able to store multiple box stacks 4 to be transported. These box stacks 4 are placed side by side on the loading device 200. Each box stack 4 corresponds to a different coordinate position. In order to facilitate the handling of the handling device 100, in this embodiment, the box stacks 4 on the loading device 200 can be numbered in sequence, and the handling device 100 can be controlled to carry the box stacks 4 one by one in the order of the numbers. Specifically, in this embodiment, the corresponding placement positions of the multiple box stacks 4 on the loading device 200 are marked as S1, S2, S3...SN in sequence, and then the handling device 100 is controlled to carry them in sequence. For example, the handling device 100 can first arrive at the S1 position to carry the box stack 4, and then arrive at S2 in sequence to carry other box stacks 4.

[0073] like Figure 2 As shown, in this embodiment, the box sheet stack 4 includes a wrapping paper 41 and a box sheet stack 43 disposed in the wrapping paper 41 and wrapped by the wrapping paper 41. The box sheet stack 43 includes a plurality of stacked box sheets 42. The box sheet stack 43 is wrapped and packaged by the wrapping paper 41 from the circumferential direction to prevent the stacked box sheets 42 from spreading. Specifically, as shown in FIG. Figure 2 As shown, in this embodiment, the top surface, bottom surface, left surface and right surface of the box stack 43 are all wrapped by wrapping paper 41. Among them, the wrapping paper 41 is kraft paper. Kraft paper can play a good bundling effect on the box stack 43.

[0074] The feeding mechanism 300 is used to feed the box stack 43 to the packaging machine for the box 42 to be used in the packaging process. Figure 1 As shown, in this embodiment, the feeding mechanism 300 includes a belt 301. When the box stack 43 is placed on the belt 301, the belt 301 conveys the box stack 43 so that the box stack 43 can be delivered to the packaging machine. Based on the provided feeding mechanism 300, the box supply system 10 can realize automatic delivery of the box 42 to the packaging machine, which is more efficient.

[0075] The transport device 100 is used to transport the box stack 4 between different workstations, such as between the loading device 200 and the cutting device 400 , between the cutting device 400 and the feeding mechanism 300 , and between the feeding mechanism 300 and the recovery device 500 .

[0076] Specifically, Figure 3 As shown, in this embodiment, the handling device 100 includes a support device 3, a robot arm 1 and a handling mechanism 2. The support device 3 is used to support the robot arm 1. The support device 3 includes a base 31. A turntable 32 is provided on the base 31. The robot arm 1 is connected to the turntable 32, so that the robot arm 1 is rotatably arranged on the support device 3. Moreover, the robot arm 1 includes at least two arm sections 11, which are connected in sequence, and two adjacent arm sections 11 are connected by a joint 12, so that the arm sections 11 can rotate relative to each other. In this way, under the action of the turntable 32 and the joint 12, the robot arm 1 has a large stroke and degree of freedom, which can better meet the needs of the entire handling process. The handling mechanism 2 is arranged at one end of the robot arm 1 away from the support device 3, and moves with the robot arm 1, so that under the drive of the robot arm 1, the handling mechanism 2 can be transferred between the loading device 200, the cutting device 400, the feeding mechanism 300 and the recovery device 500, and can be transferred between different positions of the loading device 200 to complete the handling process.

[0077] More specifically, by Figure 3 It can be seen that, in this embodiment, the transport mechanism 2 includes a mounting seat 21 , an in-position detection member 28 , an in-position detection member 27 and two transport devices 22 .

[0078] The mounting seat 21 is disposed at one end of the robot arm 1 away from the supporting device 3, so that the transport mechanism 2 is disposed at the end of the robot arm 1 away from the supporting device 3. Figure 3 As shown, in this embodiment, the mounting seat 21 is a mounting plate and is roughly rectangular. By providing the mounting seat 21, the installation and fixation of the in-situ detection member 28 and the two handling devices 22 are facilitated.

[0079] The in-place detection member 28 is arranged on the mounting seat 21, and is used to detect whether there is a box stack 4 at the target position, so as to control whether the two handling devices 22 carry the box stack at the target position. Specifically, in this embodiment, the in-place detection member 28 includes a photoelectric detector, and is configured to detect whether there is a box stack 4 at the designated position when the handling mechanism 2 reaches the designated position. If it is detected that there is a box stack 4 at the target position, the two handling devices 22 are actuated to carry the box stack 4; and if it is detected that there is no box stack 4 at the target position, the controller controls the movement of the robot arm 1, so that the robot arm 1 drives the handling mechanism 2 to move to another position, and the in-place detection member 28 further detects whether there is a box stack 4, and this continues until the in-place detection member 28 detects the box stack 4, and the controller controls the two handling devices 22 to act to carry the box stack 4.

[0080] For example, when the robot arm 1 drives the transport mechanism 2 to the pre-marked position S1, if the photoelectric detector detects that there is no box stack 4 at the corresponding position, the controller controls the robot arm 1 to continue moving from S1 to the position S2 closest to S1. If the photoelectric detector detects that there is a box stack 4 at S2, it will be transported. If the photoelectric detector detects that there is no box stack 4 at S2, the robot arm 1 will be controlled to continue moving and continue searching for the box stack 4 until it finds the box stack 4. It can be seen that the in-position detection member 28 provides a basis for the action of the two transport devices 22, so that the two transport devices 22 will perform the transport action only after the in-position detection member 28 detects the box stack 4, which is also conducive to improving the transport accuracy and thus improving the efficiency.

[0081] Two handling devices 22 are used to carry the box sheet stack 4. Figure 3 As shown, in this embodiment, two transport devices 22 are both provided on the mounting seat 21 and arranged side by side along the first direction. Moreover, the two transport devices 22 have the same structure, and both include a transport suction cup 23 and a supporting claw 24. For each transport device 22, the transport suction cup 23 and the supporting claw 24 are arranged side by side along a second direction perpendicular to the first direction. In this way, the transport mechanism 2 includes two transport suction cups 23 and two supporting claws 24. Among them, the transport suction cup 23 is configured to absorb the box stack 4 by providing suction.

[0082] In this embodiment, two transport suction cups 23 together can suck up a box stack 4, so that the two transport devices 22 are configured to transport a box stack 4 together, and at this time, the transport mechanism 2 can only transport one box stack 4 at a time. As a variation, the area of ​​the transport suction cup 23 used for contacting the box stack 4 can be increased, and the suction force of a single transport suction cup 23 can be increased, so that one transport suction cup 23 is sufficient to absorb one box stack 4. In this way, each transport device 22 can transport one box stack 4, so that the transport mechanism 2 can transport two box stacks 4 at a time, which is more efficient.

[0083] Moreover, in this embodiment, the suction force of the transport suction cup 23 is variable. Specifically, the total suction force of the two transport suction cups 23 can be changed between a first value, a second value and a third value. The first value is the suction force that can suck the entire box stack 4 (i.e., the combination of the box stack 43 and the wrapping paper 41), and then suck up the entire box stack 4. The second value is the suction force that can only suck the wrapping paper 41, but cannot suck the box stack 43, and then release the box stack 43 while keeping the wrapping paper 41 adsorbed. The third value is the suction force that cannot suck the wrapping paper 41, and then releases the wrapping paper 41. Among them, the second value and the third value are both smaller than the first value, and the third value is smaller than the second value. The third value can be 0, that is, the release of the individual wrapping paper 41 is achieved by making the suction force of the transport suction cup 23 0. In this way, the transport suction cup 23 can not only suck up the entire box stack 4, but also remove the wrapping paper 41 from the box stack 43, so that the box stack 43 without the wrapping paper 41 falls directly onto the feeding mechanism 300, and the wrapping paper 41 can also be transported alone by the feeding mechanism 300 to the recovery device 500 and placed in the recovery device 500 for recovery.

[0084] The claw 24 is used to carry the box stack 4 together with the carrying suction cup 23. Figure 3 and Figure 5 As shown, in this embodiment, the claw 24 includes a supporting rod 25 and a supporting portion 26, the supporting rod 25 is rotatably connected to the mounting seat 21, and the supporting portion 26 is arranged at one end of the supporting rod 25 away from the mounting seat 21, and protrudes toward the side where the transport suction cup 23 of the same transport device 22 is located. In this way, the claw 24 is rotatably arranged on the mounting seat 21, so that the claw 24 can rotate between the working position and the avoidance position relative to the robot arm 1 to support or avoid the box stack 4.

[0085] Depend on Figure 5 It can be seen that in this embodiment, in the working position (see Figure 5When the cassette stack 4 is in the vertical position, the supporting rod 25 is perpendicular to the surface of the mounting seat 21 facing the supporting claw 24, and is used to contact the side of the cassette stack 4 to restrain the cassette stack 4 from the side to prevent the cassette stack 4 from tipping to one side, thereby increasing the stability of transportation, and the supporting portion 26 is in contact with the bottom surface of the cassette stack 4 to support the cassette stack 4 upward, so as to realize the supporting effect of the supporting claw 24 on the cassette stack 4; while in the avoidance position (see Figure 4 The horizontal position in Figure 5 is the position between the working position and the avoidance position), the support rod 25 is parallel to the surface of the mounting seat 21 facing the support claw 24, the support claw 24 is away from the box stack 4 as a whole, and the support rod 25 and the supporting portion 26 are not in contact with the box stack 4. In this way, the working position is perpendicular to the avoidance position. During operation, the support claw 24 only needs to rotate 90° clockwise or counterclockwise to switch between the working position and the avoidance position, which is simple and convenient, and is not likely to interfere with the transport suction cup 23. Of course, the avoidance position may not be perpendicular to the working position. For example, in other embodiments, the avoidance position may also be as shown in FIG. Figure 5 The illustrated position is an inclined position relative to the surface of the mounting seat 21 facing the claw 24 .

[0086] Depend on Figure 4 It can be seen that in this embodiment, before the transport suction cup 23 starts to absorb the box stack 4, but before the box stack 4 is sucked up, the claw 24 is away from the transport suction cup 23 and is in an avoidance position. In this way, the claw 24 can be effectively prevented from affecting the transport suction cup 23 to absorb the box stack 4, thereby ensuring the efficient operation of the production line and improving the efficiency. After the transport suction cup 23 sucks up the box stack 4, as shown in FIG. Figure 5 As shown by the arrow, the supporting claw 24 rotates in the direction close to the transport suction cup 23 to reach the working position, supporting the box stack 4, so that during the transport process, the box stack 4 is simultaneously subjected to the suction force of the transport suction cup 23 and the supporting effect of the supporting claw 24, which can effectively prevent the box stack 4 from falling off, scattering or tipping over during the transport process, thereby effectively improving the transport stability and improving the transport efficiency.

[0087] When it is necessary to carry, the carrying suction cup 23 can be controlled to generate an adsorption force to hold the box stack 4 and lift it upward to lift the box stack 4, and then the claw 24 can be controlled to rotate to the working position, and the supporting portion 26 can be inserted into the lower part of the box stack 4 to contact the bottom surface of the box stack 4 to support the box stack 4 below. After that, the robot arm 1 drives the carrying mechanism 2 to move, so that the carrying mechanism 2 can carry the box stack 4 to other locations.

[0088] The position of the supporting portion 26 on the supporting rod 25 can be adjusted to match the box stack 4 of different sizes. For example, when the size of the box stack 4 is small, the position of the supporting portion 26 on the supporting rod 25 can be adjusted toward the mounting seat 21 so that the supporting portion 26 can still engage with the box stack 4.

[0089] The in-place detection member 27 is used to detect the position of the supporting claw 24 to determine whether the supporting claw 24 has reached the working position. Specifically, in this embodiment, the in-place detection member 27 includes a micro switch, and is arranged on a crossbeam (not marked) of a supporting rod 25 connecting the two supporting claws 24. By detecting whether the supporting rod 25 is in contact with the box stack 4, it is determined whether the supporting claw 24 has reached the working position. When the supporting rod 25 rotates to contact the box stack 4, the micro switch is triggered, and the micro switch sends a signal to the controller. The controller controls the supporting rod 25 to stop rotating according to the signal of the micro switch, so that the supporting claw 24 reaches and remains in the working position to support the box stack 4. Using a micro switch as the in-place detection member 27 can effectively improve the detection accuracy, enhance the control sensitivity, and accurately control the supporting claw 24 to achieve the supporting function.

[0090] As can be seen from the foregoing description, the transporting device 100 of this embodiment can transport the box sheet stack 4 accurately and stably.

[0091] The cutting device 400 is arranged on the movement path of the conveying mechanism 2 from the loading device 200 to the feeding mechanism 300, and is used to cut the wrapping paper 41 of the box sheet stack 4, so that the conveying equipment 100 can first convey the box sheet stack 4 to the cutting device 400 for wrapping paper cutting, and then transport the box sheet stack 4 with the cut wrapping paper 41 to the feeding mechanism 300, so that the conveying equipment 100 can separate the box sheet stack 43 and the wrapping paper 41 at the feeding mechanism 300, and place the box sheet stack 43 and the wrapping paper 41 on the feeding mechanism 300 and the recycling device 500 respectively.

[0092] like Figure 1 As shown, in this embodiment, the cutting device 400 is arranged on one side of the width direction of the feeding mechanism 300 and is located at the downstream end of the feeding mechanism 300 in the conveying direction of the feeding mechanism 300. Figure 1 and Figure 6-Figure 8 It can be seen that in this embodiment, the cutting device 400 cuts one side of the packaging paper 41 so that Figure 8As shown, after the wrapping paper 41 is cut, the side and bottom surfaces hang down, and the hanging parts are located on both sides of the box stack 43, while the top surface can still be sucked by the transport suction cup 23, so that the transport device 100 can conveniently transport the box stack 43 together with the cut wrapping paper 41 to the target discharge position of the feeding mechanism 300, so that the box stack 43 can still be constrained by the wrapping paper 41 to a certain extent during the process from the cutting device 400 to the target discharge position of the feeding mechanism 300, thus helping to prevent the box stack 43 from loosening during the process from the cutting device 400 to the target discharge position of the feeding mechanism 300, and avoiding the loose box stack 43 from affecting the efficiency. The specific structure of the cutting device 400 will be introduced later.

[0093] The recycling device 500 is used to recycle the packaging paper 41. Figure 1-Figure 10 As shown, in this embodiment, the recovery device 500 is a recovery container such as a barrel or a box, which is placed near the feeding mechanism 300, so that it is convenient for the handling device 100 to put the removed wrapping paper 41 into the recovery device 500 after taking it off from the box sheet stack 43 on the feeding mechanism 300. The handling device 100 is configured to drive the wrapping paper 41 to move to the recovery device 500 after placing a box sheet stack 43 on the feeding mechanism 300, release the suction force of the handling suction cup 23 on the wrapping paper 41, and make the wrapping paper 41 fall into the recovery device 500.

[0094] The working process of the box sheet supply system 10 of this embodiment is combined with Figure 4-Figure 10 The instructions are as follows:

[0095] First, under the action of the robot arm 1 of the transport device 100 , the transport mechanism 2 of the transport device 100 moves to the top of the loading device 200 and descends to a preset height slightly higher than the height of the box stack 4 .

[0096] Afterwards, if Figure 4 As shown, the handling device 100 labels the box stack 4 on the loading device 200 and identifies them in order. Specifically, the photoelectric detector on the mounting seat 21 detects whether the box stack 4 with the corresponding label exists. If there is no box stack 4 at a certain label, the handling device 100 searches in order until the box stack 4 on the loading device 200 is found. Then, the two handling suction cups 23 of the handling device 100 start to suck the box stack 4. In the corresponding process, the two supporting claws 24 of the handling device 100 are kept in the avoidance position.

[0097] When the total suction force of the two transport suction cups 23 reaches the first value, the two transport suction cups 23 suck the box sheet stack 4. Figure 5As shown, the two supporting claws 24 of the handling device 100 immediately rotate clockwise, and stop rotating when the two micro switches detect the box stack 4, and arrive at the working position to support and fix the two box stacks 4.

[0098] Then, if Figure 6 As shown, the transport device 100 takes the box stack 4 away from the loading device 200, and under the joint action of the turntable 32 and the joint 12, the transported box stack 4 is transported to the right side of the cutting device 400, and the cutting device 400 cuts the left side of the packaging paper 41, as shown in FIG. Figure 7 and Figure 8 As shown ( Figure 7 and Figure 8 The cassette stack 43 is hidden in the figure.

[0099] Then, if Fig. 9 As shown, the handling device 100 transports the cut box stack 4 to above the target discharge position of the feeding mechanism 300 (in the figure, that is, the end of the feeding mechanism 300 away from the cutting device 400), and then slowly lowers the box stack 4 to the target discharge position of the feeding mechanism 300. In the corresponding process, the supporting claw 24 that originally supported the box stack 4 rotates away from the working position, and the negative pressure of the handling suction cup 23 that originally sucked the box stack 4 is reduced, so that the suction force of the corresponding handling suction cup 23 is reduced from the first value to the second value. Under this suction force, the handling suction cup 23 can still suck the packaging paper 41, but no longer suck the box stack 43, and the box stack 43 is released. Therefore, in this case, the belt 301 of the feeding mechanism 300 moves to transport the box stack 43 and supply the box 42 to the packaging machine.

[0100] Afterwards, if Fig.10 As shown, the transport device 100 moves with the cut wrapping paper 41 to above the recycling device 500 , and closes the negative pressure of the transport suction cup 23 that sucks the wrapping paper 41 , and throws the wrapping paper 41 into the recycling device 500 , thereby completing the recycling of the wrapping paper 41 .

[0101] After the loading and feeding of the box stack 4 of a single transport is completed, the transport device 100 returns to the loading device 200 to search for the next box stack 4. During the search, the transport device 100 starts searching for the box stack 4 according to the number of the most recent box stack 4. Then, the previous steps are repeated to complete the supply of other box stacks 4.

[0102] It can be seen that the box sheet supply system 10 of this embodiment has a simple structure and high automation, and can automatically complete multiple steps such as transportation, cutting, stacking and recycling of packaging paper, and can efficiently complete the supply of box sheets 42 and effectively improve production efficiency.

[0103] Next, combine Figure 11-Figure 16, the structure and working process of the cutting device 400 of this embodiment are described.

[0104] like Figure 11-Figure 16 As shown, in this embodiment, the cutting device 400 includes a knife holder 402 , a cutting knife 401 , a suction mechanism 404 and a telescopic cylinder 407 .

[0105] The knife seat 402 is used to provide a mounting base for the cutting knife 401 , the separation mechanism 403 and the holding mechanism 406 .

[0106] The cutting knife 401 is disposed on the knife holder 402 and is used to cut the wrapping paper 41. In this embodiment, the cutting knife 401 is movably disposed on the knife holder 402, and can not only be extended relative to the knife holder 402, but also can move relative to the knife holder 402 after being extended. Figure 11-Figure 16 As shown, in this embodiment, a knife groove 40a is provided on the knife seat 402, and the cutting knife 401 is telescopically arranged in the knife groove 40a, so that the cutting knife 401 can switch between a retracted state and an extended state. Figure 11-Figure 14 As shown, the cutting knife 401 is stored in the knife groove 40a and is not exposed, which can prevent the cutting knife 401 from accidentally contacting the box sheet stack 4; when in the extended state, as shown in FIG. Fig.15 and Fig.16 As shown, the cutting knife 401 extends out of the knife groove 40a, so that the cutting knife 401 can contact with the wrapping paper 41 and cut the wrapping paper 41. Figure 11-Figure 16 As shown, in this embodiment, the cutting knife 401 is slidably disposed in the knife groove 40a, so that the cutting knife 401 can slide along the knife groove 40a after being extended (see Fig.16 The cutting knife 401 slides along the knife groove 40a to cut the wrapping paper 41. The corresponding sliding direction can be referred to as the cutting direction, and the direction opposite to the corresponding sliding direction can be referred to as the cutting reverse direction.

[0107] The suction mechanism 404 is used as a separation mechanism 403, which is arranged on the knife seat 402 and is located below the cutting knife 401. It is used to suck the packaging paper 41 toward the cutting knife 401 before and during cutting, and suck the part of the packaging paper 41 between the cutting knife 401 and the box stack 43 (that is, the part of the packaging paper 41 to be cut, that is, the left side of the packaging paper 41 in the figure) away from the box stack 43. Figure 11-Figure 16 As shown, in this embodiment, the adsorption mechanism 404 includes two separation suction cups 405, and the two separation suction cups 405 are arranged at intervals along the cutting direction, so that the adsorption mechanism 404 can adsorb the packaging paper 41 at different positions in the cutting direction, thereby improving the adsorption stability.

[0108] The telescopic cylinder 407 is disposed on the knife seat 402 and serves as a holding mechanism 406. After the suction mechanism 404 sucks the wrapping paper 41 away from the box stack 43, the cylinder 407 extends between the wrapping paper 41 and the box stack 43 to block the wrapping paper 41, so that the portion of the wrapping paper 41 between the cutting knife 401 and the box stack 43 can be stably maintained at the position reached by the suction mechanism 404. Figure 11-Figure 16 As shown, in this embodiment, the cylinder barrel 409 of the telescopic cylinder 407 is fixed on the knife seat 402, and the cylinder rod 408 which is telescopically arranged in the cylinder barrel 409 is used to be inserted between the wrapping paper 41 and the box sheet stack 43 after being extended to block the wrapping paper 41. Since the cylinder rod 408 is usually thinner than the cylinder barrel 409, it is easier to insert into the gap between the wrapping paper 41 and the box sheet stack 43, and it is more convenient to block the wrapping paper 41, thereby improving the stability and reliability of the wrapping paper 41 in the sucked-away position. And, as shown in FIG. Fig.11 and Fig.15 As shown, in this embodiment, after the cylinder rod 408 is extended into place, the portion thereof for contacting the wrapping paper 41 is located between the cutting knife 401 and the adsorption mechanism 404 in the height direction, that is, the portion of the cylinder rod 408 for contacting the wrapping paper 41 is located below the cutting knife 401 and above the adsorption mechanism 404. In this way, during the cutting process, the cylinder rod 408 will not affect the normal operation of the cutting knife 401 and the adsorption mechanism 404, and in particular, will not affect the cutting by the cutting knife 401. Therefore, it is conducive to achieving a more convenient and efficient wrapping paper cutting process.

[0109] Based on the provided adsorption mechanism 404 and the holding mechanism 406, the working process of the cutting device 400 of this embodiment is roughly as follows:

[0110] (1) Fig.12 As shown, the transport mechanism 2 transports the box stack 4 to the right side of the cutting device 400, so that the box stack 4 is located at a certain distance (e.g., 5 cm) to the right side of the cutting device 400. At this time, the cutting knife 401 of the cutting device 400 is in a retracted state, and the adsorption mechanism 404 and the telescopic cylinder 407 are not working;

[0111] (2) Afterwards, Fig.13 As shown, the transport mechanism 2 moves the box stack 4 to the left (i.e., the direction close to the cutting device 400), so that the box stack 4 is close to the cutting device 400, until the box stack 4 reaches a position where its packaging paper 41 can be adsorbed by the adsorption mechanism 404 (e.g., the position where the packaging paper 41 contacts the two separation suction cups 405 of the adsorption mechanism 404). At this time, the cutting knife 401 of the cutting device 400 is still in the retracted state, and the adsorption mechanism 404 and the telescopic cylinder 407 are still not working;

[0112] (3) Next, Fig.14As shown, the two separation suction cups 405 of the adsorption mechanism 404 are connected to negative pressure to adsorb the packaging paper 41, so that the portion of the packaging paper 41 located between the adsorption mechanism 404 and the box sheet stack 43 is close to the cutting knife 401 and away from the box sheet stack 43, forming a gap between the box sheet stack 43, and then, the conveying mechanism 2 drives the box sheet stack 43 to move a certain distance (for example, 5 cm) to the right side (i.e., away from the cutting device 400), so that the gap between the portion of the packaging paper 41 located between the adsorption mechanism 404 and the box sheet stack 43 and the box sheet stack 43 is increased, which facilitates the insertion of the telescopic cylinder 407, and then, the cylinder rod 408 of the telescopic cylinder 407 extends to the gap between the portion of the packaging paper 41 located between the adsorption mechanism 404 and the box sheet stack 43 and the box sheet stack 43, blocking the packaging paper 41 and preventing the packaging paper 41 from returning to its original position;

[0113] (4) Afterwards, Fig.15 As shown, the cutting knife 401 is extended and switched to the extended state;

[0114] (5) Then, if Fig.16 As shown, the cutting knife 401 quickly slides along the cutting direction to cut the wrapping paper 41;

[0115] (6) Afterwards, the cutting knife 401 is retracted and slides in the opposite direction of cutting to return to the initial position. Subsequently, the cylinder rod of the telescopic cylinder 407 is retracted and the negative pressure of the separation suction cup 405 is closed, completing the entire cutting process.

[0116] It can be seen from the above-mentioned cutting process that in this embodiment, before the cutting knife 401 starts cutting, the portion of the wrapping paper 41 located between the adsorption mechanism 404 and the box sheet stack 43 is separated from the box sheet stack 43 under the adsorption action of the adsorption mechanism 404, and is stably maintained at the corresponding separation position under the blocking action of the telescopic cylinder 407, so that during the cutting process of the cutting knife 401, the cut portion of the wrapping paper 41 is no longer attached to the box sheet stack 43, but has a large gap with the box sheet stack 43. Therefore, the cutting knife 401 can be effectively prevented from accidentally cutting the box sheet stack 43 during the process of cutting the wrapping paper 41, so that the quality of each box sheet 42 in the box sheet stack 43 can be effectively maintained intact, and the packaging quality and packaging efficiency can be prevented from being affected by the box sheet 42 being cut accidentally.

[0117] It can be seen that based on the provided adsorption mechanism 404 and telescopic cylinder 407, the cutting device 400 of this embodiment can achieve non-destructive cutting of the packaging paper 41, which is conducive to improving the packaging quality and packaging efficiency, and can better meet the box supply needs of packaging machines, especially faster packaging machines.

[0118] Based on the box sheet supply system 10 and the handling device 100 of the aforementioned embodiments, the present application further provides a packaging system. The corresponding packaging system includes a packaging machine and the box sheet supply system 10 of any embodiment of the present application. The packaging machine receives the box sheets 42 of the box sheet stack 4 cut by the cutting device 400 of the box sheet supply system 10. In the case where the box sheet supply system 10 includes a feeding mechanism 300, the box sheet stack 43 of the box sheet stack 4 cut by the cutting device 400 is separated from the cut wrapping paper 41 and then transported to the packaging machine via the feeding mechanism 300 to realize the box sheet supply to the packaging machine.

[0119] The above description is only an exemplary embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
