Description

Technical Field

[0001] This application relates to the field of packaging machinery technology, specifically to an integrated tray-loading and boxing machine. Background Technology

[0002] A cartoning machine is an automated device used to repack materials that have undergone initial packaging into cardboard boxes. Existing cartoning equipment is designed for foldable boxes, which are folded into a flat structure in the hopper. Therefore, the cartoning machine is equipped with a rotary box-picking and opening device, which places the opened boxes onto a conveyor chain. If inner trays are needed to hold the materials, these trays are usually made of PVC sheets through vacuum forming or compression molding and can be stacked. During use, a separating device separates them into individual inner trays and places them onto the corresponding conveyor chain. Then the material placement and boxing actions are completed; however, when the packaging box is a rigid gift box that cannot be folded and the inner tray is a non-stackable structure (such as a foam inner tray, which is a material-containing cavity formed by cutting holes in a solid surface to hold the material, and the bottom surface is a solid flat bottom) can only be stacked, the existing cartoning machine structure cannot complete the stable and continuous feeding of such packaging boxes and inner trays (that is, placing the packaging boxes and inner trays on the corresponding conveyor chain), and therefore cannot complete the material feeding and boxing functions of such packaging boxes and inner trays. Therefore, the applicant has carried out targeted research and development and proposed this case. Summary of the Invention

[0003] The purpose of this application is to provide an integrated cartoning and packing machine to solve the problems in the prior art.

[0004] To achieve the above objectives, this application provides the following technical solution: a tray-loading and boxing integrated machine, comprising a first conveyor chain and a second conveyor chain arranged side-by-side and longitudinally staggered on a main frame, wherein partitions are spaced apart along their respective longitudinal directions on the first conveyor chain and the second conveyor chain to form conveyor positions. It also includes a feeding device disposed at the front end of the first conveyor chain for supplying an inner tray to the conveying position of the first conveyor chain, a box feeding device disposed at the front end of the second conveyor chain for supplying an outer box to the conveying position of the second conveyor chain, and a material feeding device disposed on the side of the first conveyor chain away from the second conveyor chain for placing materials into the inner tray on the first conveyor chain. The feeding device includes a second conveyor belt and a first hopper, as well as a first relay component for transferring the inner tray output from the first hopper to the second conveyor belt. When the inner tray is transferred from the first relay component to the second conveyor belt, the inner tray changes from a side-standing posture to a flat posture. The box feeding device includes a third conveyor belt and a second hopper, as well as a second relay component for transferring the outer box output from the second hopper to the third conveyor belt. When the outer box is transferred from the second relay component to the third conveyor belt, the outer box changes from a side-standing posture to a flat posture. The feeding device includes a material handling device and a robotic arm for transferring the material output from the material handling device to the inner tray; It also includes a second push assembly located at the end of the first conveyor chain for pushing the inner tray containing the material into the outer box on the second conveyor chain.

[0005] Furthermore, the first hopper includes a first conveyor belt, guide plates disposed on both sides of the first conveyor belt, and a first sensor disposed at a predetermined position above the path of the first conveyor belt.

[0006] Furthermore, the inner side of the guide plate is equipped with several rolling elements, and the rotation direction of the rolling elements is consistent with the travel direction of the first conveyor belt.

[0007] Furthermore, the first relay component includes a top plate and a bottom plate connected by columns and spaced apart, and a material plate located between the top plate and the bottom plate and guided by the columns by sliding. The columns are perpendicular to the first conveyor belt, and the material plate is driven by a first drive member to run along the columns. It also includes a feeding pusher located at the lower end of the top plate and driven by a second drive member. When the material plate is flush with the output end of the first conveyor belt, it receives a set of inner supports from the first conveyor belt. When the material plate moves up the columns to a position higher than the second conveyor belt, the feeding pusher pushes the inner supports to leave the material plate in sequence according to a set step distance and rhythm and then lay them flat on the second conveyor belt.

[0008] Furthermore, the first relay assembly also includes a rear baffle mounted on the material plate relatively far from the first conveyor belt and a side baffle relatively far from the second conveyor belt for limiting the inner tray entering the material plate; it also includes a aligning plate for aligning the inner tray entering the material plate toward the rear baffle.

[0009] Furthermore, the first relay component also includes a limit switch for detecting when the feeding pusher reaches the limit pushing position and a second sensor for detecting when the inner support enters the set position of the material plate.

[0010] Furthermore, the integrated box-filling machine also includes a lower box assembly located at the end of the third conveyor belt for sequentially transferring the outer boxes into the conveyor slots of the second conveyor chain; the third conveyor belt is higher than the second conveyor chain; the lower box assembly includes a support frame spanning the second conveyor chain and a box clamping plate connected to the output end of the third conveyor belt and capable of moving closer or further apart from each other; It also includes a suction cup disposed above the receiving box clamping plate and capable of vertical displacement. When the receiving box clamping plate receives an outer box output from the third conveyor belt, the suction cup descends a set stroke to hold the outer box. Then, the receiving box clamping plates move away from each other to form a channel for the outer box to descend, so that the outer box is released into the conveying position corresponding to a second conveyor chain when it descends with the suction cup to a set position.

[0011] Furthermore, the suction cup has several arrays installed at the lower end of the floating seat, the floating seat is connected to the output end of the first-stage cylinder, the first-stage cylinder is connected to the output end of the second-stage cylinder, and the stroke of the first-stage cylinder is less than that of the second-stage cylinder; the receiving box clamping plates are respectively installed at the two output ends of the finger clamping cylinder, and the finger clamping cylinder is supported by a horizontal plate connected to the support frame.

[0012] Furthermore, the integrated boxing and tray filling machine also includes a brake plate for braking the outer box at the upper end of the third conveyor belt.

[0013] Furthermore, the integrated tray-filling and boxing machine also includes a baffle plate located at the end of the second conveyor belt and a first horizontal push assembly located in front of the baffle plate. The first horizontal push assembly includes a box-moving push head and a force-applying component for driving the box-moving push head to move. The box-moving push head is used to push the inner tray on the second conveyor belt into the conveying position of the first conveyor chain.

[0014] The beneficial technical effects of this application are as follows: The integrated tray and carton filling machine provided by this application uses two conveyor belt hoppers to transport inner trays and outer boxes, allowing the inner trays and outer boxes to be placed upright on the corresponding hopper conveyor belts. This provides a large capacity and avoids frequent replenishment of inner trays or outer boxes. By setting up a relay component, a set of inner trays or outer boxes can be extracted. When transferred from the relay component to the corresponding conveyor belt, the inner trays or outer boxes are automatically and sequentially flipped and flattened, so that the inner trays or outer boxes are in a position to receive materials or be placed in the tray. This effectively increases the buffer capacity of the stored inner trays or outer boxes and facilitates a stable supply of inner trays and outer boxes. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] Please see Figure 1-11 A boxing and traying integrated machine includes a first conveyor chain 2 and a second conveyor chain 3 arranged side-by-side and longitudinally staggered on a main frame 1. Partitions 4 are spaced apart along the longitudinal direction of each of the first conveyor chain 2 and the second conveyor chain 3 to form conveyor positions. It also includes a feeding device located at the front end of the first conveyor chain 2 for supplying the inner tray 26 to the conveying position of the first conveyor chain 2, a box feeding device located at the front end of the second conveyor chain 3 for supplying the outer box 27 to the conveying position of the second conveyor chain 3, and a material feeding device located on the side of the first conveyor chain 2 away from the second conveyor chain 3 for placing materials into the inner tray 26 on the first conveyor chain 2. The feeding device includes a second conveyor belt 16 and a first hopper 9, as well as a first relay assembly 11 for transferring the inner tray 26 output from the first hopper 9 to the second conveyor belt 16. When the inner tray 26 is transferred from the first relay assembly 11 to the second conveyor belt 16, the inner tray 26 changes from a side-standing posture to a flat posture. The box feeding device includes a third conveyor belt 24 and a second hopper 10, and a second relay assembly 12 for transferring the outer box 27 output from the second hopper 10 to the third conveyor belt 24. When the outer box 27 is transferred from the second relay assembly 12 to the third conveyor belt 24, the outer box 27 changes from a side-standing posture to a flat posture. The feeding device includes a material sorting device 6 and a robot arm 5 for transferring the material output from the material sorting device 6 to the inner tray 26. In this embodiment, the material sorting device 6 and the robot arm 5 can be selected from the existing material sorting device 6 and robot arm 5 according to different materials to be packed. That is, when the inner tray 26 is conveyed to the working area of ​​the robot arm 5 by the conveying position on the first conveying chain 2, the robot arm 5 picks up the material sorted at the output of the material sorting device 6 and transfers it into the material receiving cavity on the inner tray 26. The synchronous control between the robot arm 5 and the first conveying chain 2 is controlled by the electrical control system of the tray loading and boxing machine. It also includes a second horizontal push assembly 20 located at the end of the first conveyor chain 2 for pushing the inner tray 26 containing materials into the outer box 27 on the second conveyor chain 3; in this embodiment, the second horizontal push assembly 20 can adopt the same structure as the first horizontal push assembly 13, that is, both include a force-applying component 1301 as a driving source and a box-moving push head 1302 for pushing the inner tray 26 from the conveyor position on the first conveyor chain 2 into the outer box 27 on the corresponding conveyor position on the second conveyor chain 3. The force-applying component can be either a cylinder or a servo linear module. In this embodiment, a servo linear module is used, and the box-moving push head 1302 is installed at the output end of the servo linear module. It is understood that the servo linear module can be a commercially available product, and the servo linear module can be installed and connected to the frame 1 through structural components such as supports or uprights. As a preferred embodiment, a prior art instruction manual addition device 7 can be provided on one side of the first conveyor chain 2 to place instruction manuals into the inner tray 26 already filled with materials, covering the surface of the materials; a visual inspection sensor 8 can also be provided above the first conveyor chain 2, located between the second horizontal push assembly 20 and the instruction manual addition device 7, to detect whether the instruction manual is placed in place; it is understood that the visual inspection sensor 8 is electrically connected to the electronic control system of the tray-loading and boxing machine, so that when the instruction manual is detected not to have entered the preset position (i.e., a defective product is found), the electronic control system of the tray-loading and boxing machine will issue an audible and visual warning, and further suspend the entire machine or control the subsequent operation of the finished product pusher 23; that is, when the defective product reaches the position of the finished product pusher 23 along the conveyor slot on the second conveyor chain 3, the finished product pusher 23 does not move, and is directly output from the end of the second conveyor chain 3 to the defective product collection container, such as a collection box (not shown); when a qualified product passes the position of the finished product pusher 23, the finished product pusher 23 moves to push the qualified product onto the finished product conveyor belt 25. Please refer to the following for details. Figure 1 and Figure 2 The finished product conveyor belt 25 is installed on the other side of the end of the second conveyor chain 3. The finished product pusher 23 can be driven by a similar linear drive structure such as a cylinder or servo linear module. It is set at the end of the second conveyor chain 3. In this embodiment, the finished product pusher 23 and its driving components adopt the same structure as the first horizontal push assembly 13 and are under the unified control of the electrical control system of the tray boxing machine.

[0019] With the above configuration, the tray-loading and boxing machine provided in this application uses two conveyor belt hoppers to transport inner trays and outer boxes, allowing the inner trays 26 and outer boxes 27 to be placed sideways on the conveyor belts of the corresponding hoppers. This provides a large capacity and avoids frequent replenishment of inner trays 26 or outer boxes 27. By setting up corresponding first relay components 11 or second relay components 12, a set of inner trays 26 or outer boxes 27 can be extracted. When transferred from the corresponding first relay component 11 or second relay component 12 to the corresponding conveyor belt (second conveyor belt 16 or third conveyor belt 24), the inner trays 26 or outer boxes 27 are automatically and sequentially flipped and laid flat, so that the inner trays 26 or outer boxes 27 are in a position to receive materials or be trayed, effectively increasing the buffer capacity of the inner trays 26 or outer boxes 27 and facilitating a stable supply of inner trays 26 and outer boxes 27.

[0020] For further preferred embodiments, please refer to Figure 1-11 The first hopper 9 includes a first conveyor belt 901, guide plates 902 on both sides of the first conveyor belt 901, and a first sensor 906 positioned above the path of the first conveyor belt 901. In this embodiment, the first conveyor belt 901 is driven by a servo motor, thereby enabling joint control with the electrical control system of the tray-packing machine. The guide plates 902 keep the inner tray 26 in a stable side-standing state on the first conveyor belt 901 and allow it to move forward steadily, preventing it from tipping over. The first sensor 906 is used to detect the minimum allowable amount of inner tray 26 on the first conveyor belt 901. When the first sensor 906 detects that there is no material at its position, it sends a replenishment signal.

[0021] For further preferred embodiments, please refer to Figure 1-11 Several rolling elements 903 are arranged in an array on the inner side of the guide plate 902. The rotation direction of the rolling elements 903 is consistent with the travel direction of the first conveyor belt 901. Please refer to this for details. Figure 6 In this embodiment, the rolling element 903 can be a bearing, wherein multiple bearings are installed on the shaft 904 to form a row of rolling elements. The bearings of two adjacent rows of rolling elements are staggered in the axial direction and overlap at least once in the radial direction, thus ensuring better guidance and friction reduction for the inner support 26 or the outer box 27 to move forward. Both ends of all shafts 904 are supported by beams 905, and countersunk holes are added on opposite sides of beams 905. The two ends of shafts 904 are installed in the countersunk holes, and beams 905 are fixedly installed on guide plates 902 by fasteners. In this embodiment, guide plates 902 are sheet metal bent into a U-shape, and beams 905 are installed on the two bent sides. Guide plates 902 can be connected to the support components of the first conveyor belt 901 through structural components such as support plates.

[0022] For further preferred embodiments, please refer to Figure 1-11The first relay assembly 11 includes a top plate 1102 and a bottom plate 1116 connected and spaced apart by columns 1101, and a material plate 1103 located between the top plate 1102 and the bottom plate 1116 and slidably guided by the columns 1101. In this embodiment, the bottom plate 1116 of the first relay assembly 11 is mounted on a sub-frame 15, which serves as the support base for the first hopper 9. The first conveyor belt 901 is also supported by the sub-frame 15. The columns 1101 are perpendicular to the first conveyor belt 901. The material plate 1103 is driven by the first driving member 1104 to move along the columns 1101. The system also includes a feeding pusher 1112 located at the lower end of the top plate 1102 and driven by a second drive unit 1111. When the material plate 1103 descends along the column 1101 to be flush with the output end of the first conveyor belt 901, it receives a set of inner supports 26 from the first conveyor belt 901. When the material plate 1103 rises along the column 1101 to a position higher than the second conveyor belt 16, the feeding pusher 1112 pushes the inner supports 26 away from the material plate 1103 in sequence according to the set step distance and rhythm, and they lie flat on the second conveyor belt 16. Here, the second conveyor belt 16 can be understood as... The speed of the feeding pusher 1112 is matched with the push-out rhythm of the feeding pusher 1112 to avoid overlapping between adjacent inner trays 26. That is, when the latter inner tray 26 falls onto the second conveyor belt 16, the former inner tray 26 has already moved away from the relevant area. The second drive unit 1111 is a servo linear module installed at the bottom of the top plate 1102, and the feeding pusher 1112 is installed at the output end of the servo linear module. This allows for precise control of the step distance and rhythm of the feeding pusher 1112, ensuring that the feeding pusher 1112 pushes out only one inner tray 26 at a time onto the second conveyor belt 16. The conveyor belt 16 is fed onto the conveyor belt. As a specific embodiment, the first driving component 1104 can be a cylinder or a servo linear module type driving device. In this embodiment, the first driving component 1104 is a cylinder. Therefore, in this embodiment, an adjustable limit seat 1105 is installed on the upper part of the column 1101 to control the end position of the material plate 1103 after it rises. Its descending position can be controlled by the retraction stroke of the cylinder or by installing the same limit seat 1105 on the lower part of the column 1101 to control the material plate 1103 and the conveying surface of the first conveyor belt 901 to maintain the optimal positional fit.

[0023] For further preferred embodiments, please refer to Figure 1-11The first relay assembly 11 also includes a rear baffle 1106 mounted on the material plate 1103 and located relatively far from the first conveyor belt 901, and a side baffle 1107 mounted relatively far from the second conveyor belt 16, for limiting the inner support 26 entering the material plate 1103, thereby maintaining the consistency of the inner support 26's position on the material plate 1103 and preparing it for entering the second conveyor belt 16; it also includes a mechanism for orienting the inner support 26 entering the material plate 1103 toward the rear baffle 1106. In this embodiment, the aligning plate 1109 is driven by the aligning cylinder 1110 installed at the bottom of the top plate 1102, so that the aligning plate 1109 can reciprocate toward the rear baffle 1106. In addition, in order to facilitate the feeding pusher 1112 to exit the material plate 1103 to the reset position, a notch 1108 is provided on the side baffle 1107 so that the feeding pusher 1112 can pass through the side baffle 1107 smoothly and avoid mechanical interference.

[0024] For further preferred embodiments, please refer to Figure 1-11 The first relay component 11 also includes a limit switch 1115 for detecting when the feeding pusher 1112 reaches its limit pushing position, and a second sensor 1114 for detecting when the inner support 26 enters the set position of the material plate 1103. Here, the limit switch 1115 can be used as redundant protection or as a signal for the end of pushing. The working principle of the first relay component 11 is as follows: when the feeding pusher 1112 touches the limit switch 1115 or reaches the set stroke of the second drive component 1111, the feeding pusher 1112 quickly retracts and resets. At this time, the second sensor 1114 detects that there is no material on the material plate 1103. Simultaneously, the second drive component 1112... A drive unit 1104 lowers the material plate 1103 to a position flush with or slightly lower than the first conveyor belt 901, thereby starting the servo motor of the first conveyor belt 901. This causes the first conveyor belt 901 to advance forward a step length equal to the length of an inner tray 26, feeding a set of inner trays 26 onto the material plate 1103. When the second sensor 1114 detects the inner trays 26, the first conveyor belt 901 stops, and the material plate 1103 rises to a set height. Driven by the aligning cylinder 1110, the aligning plate 1109 pushes the inner trays 26 towards the rear baffle 1106 for alignment. Then, the feeding pusher 1112 actuates, pushing out the inner trays 26 one by one. Please refer to the following for details. Figure 10 and Figure 11 When the inner tray 26 is pushed out, once the center of gravity deviates from the edge of the material plate 1103, the inner tray 26 immediately flips over onto the second conveyor belt 16, changing from a side-standing position to a lying position, and so on. It can be understood that when the inner tray 26 is placed on the first conveyor belt 901, the front and back sides of the inner tray 26 have been distinguished and placed as required. In this embodiment, the first relay component 11 is also equipped with a wire groove 1113 on the reset side of the feeding pusher 1112 for passing through the electrical signal lines of the second drive component 1111, the limit switch 1115, and the air pipe of the alignment cylinder 1110.

[0025] For further preferred embodiments, please refer to Figure 1-11 The boxing and traying machine also includes a lower box assembly 14 located at the end of the third conveyor belt 24 for sequentially transferring the outer box 27 into the conveyor slot of the second conveyor chain 3; the third conveyor belt 24 is higher than the second conveyor chain 3; the lower box assembly 14 includes a support frame 1401 spanning the second conveyor chain 3 and a box clamping plate 1410 connected to the output end of the third conveyor belt 24 and which can move closer or further away from each other; It also includes a suction cup 1407 located above the receiving box clamping plate 1410 and capable of vertical displacement. When the receiving box clamping plate 1410 receives an outer box 27 output from the third conveyor belt 24, the suction cup 1407 descends a set stroke to hold the outer box 27. Then, the receiving box clamping plates 1410 move away from each other to form a channel for the outer box 27 to descend, so that the outer box 27 is released into the corresponding conveying position of a second conveyor chain 3 as the suction cup 1407 descends to the set position.

[0026] For further preferred embodiments, please refer to Figure 1-11The suction cups 1407 are arranged in an array at the lower end of the floating seat 1405. The floating seat 1405 is connected to the output end of the first-stage cylinder 1402, and the first-stage cylinder 1402 is connected to the output end of the second-stage cylinder 1404. The stroke of the first-stage cylinder 1402 is less than that of the second-stage cylinder 1404. The receiving box clamping plates 1410 are respectively installed at the two output ends of the finger clamping cylinder 1409. The finger clamping cylinder 1409 is supported by the horizontal plate 1408 connected to the support frame 1401. In this embodiment, the receiving box clamping plate 1410 has an L-shaped structure, that is, it has a vertical clamping edge 1411 and a horizontal bearing edge 1411. The material receiving edge 1412 has a front end that is adapted to the third conveyor belt 24, meaning its front end is close to the turning position of the third conveyor belt 24 with a gap to ensure the operation of the third conveyor belt 24. Its height is flush with or slightly lower than the conveying surface of the third conveyor belt 24. In this embodiment, the end of the material receiving edge 1412 is provided with a guide slope. Simultaneously, the front end of the clamping edge 1411 is also provided with an outwardly extending guide section to facilitate the entry of the outer box 27 on the third conveyor belt 24 onto the material receiving edge 1412. Here, when the two output ends of the clamping finger cylinder 1409 retract and reset, the box clamp... The holding plate 1410 is also brought close to make the width between the clamping edges 1411 match the length of the outer box 27, and the receiving box clamping plate 1410 is in a receiving state; in this embodiment, a fourth sensor 1413 is installed above one side of the receiving box clamping plate 1410 to detect whether the receiving box clamping plate 1410 has received the outer box 27. When an outer box is detected, the first-stage cylinder 1402 moves down to press the suction cup 1407 mouth face against the surface of the outer box 27. At the same time, the external negative pressure source uses the air pipe to make the suction cup 1407 suck up the outer box 27. Then the receiving box clamping plates 1410 move away from each other, so that the receiving edge 1412 is disengaged. When the outer box 27 is opened, the output end of the secondary cylinder 1404 extends, allowing the suction cup 1407 to continue descending to a set height. After the suction cup 1407 is released, the outer box 27 falls into the conveying slot of the second conveyor chain 3 below it, completing the unloading action. As a further preferred embodiment, in order to ensure the stability and smoothness of the floating seat 1405 when it moves up and down, a guide rod 1403 is also provided on the floating seat 1405 to slide and cooperate with the support frame 1401. At the same time, in order to facilitate the installation and connection, a connecting seat 1406 is also installed on the output end of the secondary cylinder 1404 to fix and connect the cylinder body of the primary cylinder 1402.

[0027] For further preferred embodiments, please refer to Figure 1-11The boxing and packaging machine also includes a brake plate 21 for braking the outer box 27 at the end of the third conveyor belt 24. In this embodiment, the brake plate 21 is driven by a brake cylinder 22 installed on the outside of the third conveyor belt 24. When an outer box 27 on the third conveyor belt 24 enters the box receiving clamping plate 1410, the brake cylinder 22 extends and pushes the brake plate 21 to press the last outer box 27 on the third conveyor belt 24 onto the side guide rail 28 on the third conveyor belt 24, so as to prevent the subsequent outer box 27 from falling out of the third conveyor belt 24 after the box receiving clamping plate 1410 is opened.

[0028] For further preferred embodiments, please refer to Figure 1-11 The integrated box-filling machine also includes a baffle plate 17 located at the end of the second conveyor belt 16 and a first horizontal push assembly 13 located in front of the baffle plate 17. The first horizontal push assembly 13 includes a box-moving push head 1302 and a force-applying component 1301 for driving the box-moving push head 1302 to move. The box-moving push head 1302 is used to push the inner tray 26 on the second conveyor belt 16 into the conveying position of the first conveyor chain 2. A third sensor 18 is installed in front of the baffle plate 17 to detect whether the inner tray has reached the position of the baffle plate 17. That is, the box-moving push head 1302 only moves after the inner tray 26 has reached the position of the baffle plate 17. In this embodiment, a lifting cylinder 29 is installed between the output end of the box-moving push head 1302 and the force-applying component 1301. Thus, when performing the pushing stroke... The transfer box pusher 1302 descends, making contact with the outer side of the inner tray 26, thereby pushing the inner tray 26 forward. After the pushing stroke ends, the lifting cylinder 29 retracts, causing the transfer box pusher 1302 to rise and then reset with the force application component 1301, thereby avoiding affecting the subsequent inner tray 26. At the same time, in order for the inner tray 26 to be smoothly pushed from the second conveyor belt 16 into the conveying slot of the first conveyor chain 2 and from the conveying slot of the first conveyor chain 2 into the conveying slot of the second conveyor chain 3, this embodiment provides bridging channels 19 between the second conveyor belt 16 and the first conveyor chain 2 and between the first conveyor chain 2 and the second conveyor chain 3, respectively. The bridging channel 19 can be a U-shaped structure made of sheet metal or a structure assembled by connecting multiple plates with fasteners.

[0029] In addition, in this example, the second relay component 12 adopts the same structure as the first relay component 11, and its working principle is the same as that of the first relay component 11; and the synchronization between the first conveyor chain 2 and the second conveyor chain 3, between the second conveyor chain 3 and the lower box component 14, and between the second relay component 12 and the first relay component 11 can all be controlled by the electronic control system of the boxing machine, which can be a servo control system; the first sensor 906, the second sensor 1114, the fourth sensor 1413 and the third sensor 18 can be laser sensors.
