Description

Technical Field

[0001] The present invention relates to a packaging machine, in particular to a material box packing machine. Background Art

[0002] After product production is complete, they need to be boxed and packaged. With the advancement of technology, some mechanical boxing and packaging equipment has emerged on the market to replace manual boxing and packaging, improving boxing efficiency. Current mechanical boxing and packaging equipment typically uses a robot to directly grab the product and transfer it into an upward-opening box. However, this type of boxing equipment can generally only place the product horizontally or vertically into the box, and cannot adjust the boxing method to suit different usage requirements, resulting in poor flexibility. Therefore, there is an urgent need for a material boxing machine that can realize multiple boxing methods. Summary of the Invention

[0003] The object of the present invention is to provide a material packing machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problems is:

[0005] A material packing machine comprises: a first conveying device; a posture conversion mechanism, comprising a material rack, a clamping plate and a push plate, the material rack can rotate along a horizontal axis, one side of the material rack is a discharge port, the push plate can move on the material rack in a direction close to or away from the discharge port, the side of the material rack close to the discharge port is a material clamping side, and the clamping plate can move on the material rack in a direction close to or away from the material clamping side; a transfer mechanism, having a transfer suction cup that can move back and forth between the first conveying device and the material rack; a second conveying device, located at the discharge port; a box turning mechanism, comprising a third conveying device and a first box turning module, the third conveying device is located next to the second conveying device, the first box turning module is arranged on the third conveying device, and the first box turning module has a first turning rack for turning boxes; a transfer mechanism, having a transfer plate that can move back and forth between the conveying end of the second conveying device and the third conveying device.

[0006] This technical solution has at least the following beneficial effects: the first conveying device is used to input materials to be packed, and when it moves to the side of the material rack, the transfer suction cup in the transfer mechanism moves to the first conveying device, sucks up the materials and transfers them to the material rack. After the materials are stacked and arranged on the material rack, a variety of discharge methods can be performed according to different packing needs. For example, the push plate moves in the direction close to the discharge port to push the materials in the material rack directly to the second conveying device located at the discharge port; or the splint moves toward the material clamping side to push the materials toward the material clamping side, and first adjust the placement of the materials on the material rack, and then the push plate in the pushing assembly moves in the direction close to the discharge port to push the materials between the splint and the material clamping side to the second conveying device located at the discharge port, so as to adjust the placement of the materials before pushing them out; or the splint moves toward the material clamping side to press the materials against the material clamping side, and at this time the materials are clamped between the push plate and the material clamping side. The second conveying device transports the material to the transfer mechanism, and at the box turning mechanism, the third conveying device is used to load the packed box. In the conveying process, the first turning frame turns the box over and over so that the packaging port of the box faces the transfer mechanism. At this time, the transfer plate in the transfer mechanism approaches the third conveying device, pushes the material in the transfer mechanism into the box, and completes the material packing. In this way, the posture of the material can be adjusted according to different packing requirements, which improves the flexibility and convenience of material packaging. Moreover, the material can be directly pushed into the box by turning the box over and over, which greatly improves the packing efficiency.

[0007] As a further improvement of the above technical solution, the third conveying device includes a loading conveyor, a box conveyor and a unloading conveyor arranged in sequence along the left and right directions. The loading conveyor has a plurality of loading rollers arranged at intervals along the left and right directions, and the side horizontally perpendicular to the conveying direction of the box conveyor is the feeding side. The first box turning module is located at a position of the loading conveyor close to the box conveyor, and the first turning frame is located between the two loading rollers. The first turning frame can move in the front and back directions and rotate along the axis in the left and right directions. The first turning frame is located at a position close to the feeding side and is formed with a first limit rod extending upward. The first turning frame is located between the two loading rollers and is formed with a first turning rod. The loading conveyor, the packing conveyor and the unloading conveyor are arranged in sequence. The packaging boxes can be loaded on the loading conveyor, transferred for packing on the packing conveyor and unloaded on the unloading conveyor in sequence. The loading conveyor is provided with a plurality of loading rollers arranged at intervals along the left and right directions. The plurality of loading rollers rotate to drive the packaging boxes to be transported to the packing conveyor, and the interval space between two adjacent loading rollers can provide space for the first turning frame in the first turning module to move. When the packaging box moves to the position where the loading conveyor is close to the packing conveyor, the packaging box is located above the first turning rod, and the first limit rod is located on the side of the packaging box close to the feeding side. When the packaging box needs to be turned over, the first turning frame moves in the direction away from the feeding side and rotates along the axis in the left and right directions. At this time, the first turning rod rotates upward and protrudes from the loading The roller lifts the packaging box to a position away from the feeding side, so that the packaging box slides along the first tipping rod to one side of the first limiting rod, and the packaging box is limited by the first limiting rod, and the packaging box is gradually flipped and laid down. After completion, the flipped packaging box is transported to the packing conveyor, and the material can be loaded into the packaging box at the feeding side to realize material packing. Then the packing conveyor sends the packaging box to the unloading conveyor, and the unloading conveyor moves the packaging box to the next workstation. In this way, the first tipping frame is used to flip from the bottom side of the packaging box and keep the packaging box limited, which effectively prevents damage during the laying process of the packaging box, and realizes stable and efficient flipping and laying down of the packaging box. The rotation axis of the first tipping frame moves as the packaging box is flipped, which can better save the space required for flipping and laying down the packaging box, and is more practical.

[0008] As a further improvement to the above technical solution, the transfer mechanism includes a transfer pallet, a first side plate, and a transfer drive. The transfer pallet is located between the conveying end of the second conveying device and the feed side. The first side plate is connected to the side of the transfer pallet away from the second conveying device, and the first side plate extends above the second conveying device. The transfer drive is arranged above the transfer pallet, and the transfer drive drives the transfer plate, and the transfer drive can drive the transfer plate to move back and forth. After the second conveying device transfers the material to the conveying end, the first side plate limits and blocks the material to position the material. Then, the transfer drive provides a driving force to the transfer plate, driving the transfer plate to move toward the feed side and push the material onto the transfer pallet. When the packaging box moves to the feed side position, the transfer plate continues to push the material on the transfer pallet into the packaging box to complete the packing of the material. Then, the transfer drive drives the transfer plate to return to its original position to prepare for the next transfer of material.

[0009] As a further improvement of the above technical solution, the transfer pallet is connected to a second side plate on the side close to the second conveying device, and a connecting rod is connected between the top side of the first side plate and the top side of the second side plate, and a hole is formed between the connecting rod, the first side plate, the second side plate and the transfer pallet, and the first side plate, the second side plate, the connecting rod and the transfer pallet are respectively connected to box supporting plates, and multiple box supporting plates are inclined and extended toward the center direction of the hole, and the position of the box conveyor away from the feeding side is connected to a box pushing drive component, and the box pushing drive component drives a box pushing component, and the box pushing drive component can drive the box pushing component to approach or away from the hole. The first side panel and the second side panel on the transfer pallet can form a space for limiting the material in the left and right directions. When the material is pushed into the transfer pallet, the first side panel and the second side panel can limit the left and right sides of the material, so that the material can be accurately pushed into the packaging box. When the packaging box moves to the hole position, the box pushing drive member drives the box pushing member to approach the hole and pushes the packaging box toward the hole. Since the connecting rod, the first side panel, the second side panel and the transfer pallet are respectively connected with the box supporting plates, and multiple box supporting plates are inclined toward the hole, when the packaging box approaches the hole, the ends of the multiple box supporting plates can be directly inserted into the packaging box, and as the packaging box gradually moves toward the transfer pallet, the box supporting plates can gradually open the cover plate at the opening position of the packaging box to the four sides, thereby ensuring that the material can be smoothly loaded into the packaging box.

[0010] As a further improvement to the above technical solution, a bidirectional screw is provided on the bottom side of the transfer tray. The bidirectional screw has two movable ends that can move toward or away from each other in the left-right direction. The first side panel and the second side panel are respectively connected to the two movable ends. According to the left-right width requirements of different materials, the two movable ends of the bidirectional screw can be adjusted so that the first side panel and the second side panel move toward or away from each other at the same time. In this way, the distance between the first side panel and the second side panel can be adjusted to better adapt to the size requirements of different materials and improve overall versatility.

[0011] As a further improvement of the above technical solution, the first box turning module includes a first box turning drive, a first slide and a first connecting rod. The first box turning drive is connected to the position of the loading conveyor below the loading roller. The first box turning drive drives the first slide. The first box turning drive can drive the first slide to move in the forward and backward directions. The bottom of the first limit rod is rotatably connected to the first slide, and the two ends of the first connecting rod are respectively rotatably connected to the bottom side of the first turning rod and the side of the loading conveyor away from the feeding side. When the package box is turned over and laid out of the feeding conveyor, the first box turning driving member drives the first slide to move in the direction away from the feeding side. Since the first turning rod is connected to the position of the feeding conveyor away from the feeding side by the first connecting rod, the first turning rod moves in the direction away from the feeding side while rotating upward, and drives the first limit rod to rotate downward as well. In this way, the first turning frame can turn the package box over and lay it down, and the rotation axis of the first turning frame can move synchronously, reducing the space required in the front and rear direction. When the turned and laid package box is transferred out of the feeding conveyor, the first box turning driving member drives the first turning frame to move in the direction close to the feeding side, so that the first turning frame is reversed and reset.

[0012] As a further improvement of the above technical solution, the packing conveyor includes two conveyor belts spaced apart in the front-to-back direction, a fixed frame is provided between the two conveyor belts, a connecting seat is provided in the fixed frame, a transmission block and a telescopic drive member are rotatably connected to the connecting seat, one end of the telescopic drive member is rotatably connected to the eccentric position of the bottom of the transmission block, and a baffle is connected to the top side of the transmission block. When the package box moves to the two conveyor belts, the two conveyor belts rotate synchronously to realize the transfer of the package box on the packing conveyor. When the package box is moved into place, the two conveyor belts stop working and use the baffle on the top side of the transmission block to block and limit the package box so that the package box can be accurately moved into place, and then the products to be boxed are packed into the package box. After completion, the telescopic drive member drives the transmission block to rotate, causing the baffle to rotate and descend, and the two conveyor belts continue to work to send the completed package box to the unloading conveyor. In this way, the package box can be transported into, positioned, and sent out on the packing conveyor.

[0013] As a further improvement of the above technical solution, the transfer mechanism also includes a second box turning module, the unloading conveyor is provided with a plurality of unloading rollers spaced apart along the left and right directions, the second box turning module is located at a position of the unloading conveyor close to the packing conveyor, the second box turning module is provided with a second turning frame between the two unloading rollers, the second turning frame can move in the front and rear directions and rotate along the axis in the left and right directions, the second turning frame is located at a position away from the feeding side and is formed with a second limit rod extending upward, and the second turning frame is located between the two loading rollers and is formed with a second turning rod. The unloading conveyor is provided with a plurality of unloading rollers arranged at intervals along the left and right directions, and the plurality of unloading rollers rotate to realize sending out the packaged box, and the interval space between two adjacent unloading rollers can provide space for the second turning frame in the second turning box module to move. When the box moves to the position of the unloading conveyor close to the packing conveyor, the box is located above the second turning rod, and the second limit rod is located on the side of the box away from the feeding side. When the box needs to be turned over, the second turning frame moves toward the feeding side and rotates along the axis of the left and right directions. At this time, the second turning rod rotates upward and protrudes from the unloading roller, lifting the position of the box close to the feeding side, so that the box slides along the second turning rod to one side of the second limit rod, and the second limit rod limits the box, gradually realizing the turning back to the right side. After completion, the opening of the box faces upward, and the unloading roller continues to move to convey the turned box to the next workstation.

[0014] As a further improvement of the above technical solution, the posture conversion mechanism includes a rotary drive member, a first translation drive member, a connecting frame and a pusher translation drive. The rotary drive member drives and connects the material rack, and the rotary drive member can drive the material rack to rotate. The first translation drive member is connected to the material rack, and the first translation drive member drives and connects the connecting frame. The first translation drive member can drive the clamping plate close to or away from the clamping side. The clamping plate is arranged on the connecting frame, and the pusher translation drive member is connected to the material rack. The pusher translation drive member drives and connects the push plate, and the pusher translation drive member drives the push plate close to or away from the discharge port. The rotary drive member provides a rotating driving force to the material rack, which can drive the material rack to rotate along the horizontal axis, thereby turning the material on the material rack to adjust the material placement. For example, when the material is loaded onto the material rack, it is in a horizontal state. As the material rack rotates, the material rack can be turned to a vertical state. The first translation drive member provides a translational force to the splint along the direction close to or away from the material clamping side. The connecting frame can extend the installation position of the splint so that the splint can be directly opposite to the middle position of the material clamping side, thereby better acting on the material. When working, the first translation drive member is used to The connecting frame drives the clamping plate close to the clamping side to clamp the material, or the first translation drive member drives the clamping plate away from the clamping side through the connecting frame to release the clamping of the material. The pushing translation drive member provides a driving force for the push plate to move in the direction of approaching or away from the discharge port. When the material needs to be pushed to the next workstation, the pushing translation drive member drives the push plate close to the discharge port, and uses the push plate to push the material to the discharge port. Then the pushing translation drive member drives the push plate away from the discharge port to reset and prepare for the next material push.

[0015] As a further improvement to the above technical solution, a second translation drive is connected between the connecting frame and the clamping plate, and the second translation drive can drive the clamping plate toward or away from the material clamping side. The second translation drive further provides a driving force for the clamping plate to move in a direction toward or away from the material clamping side. During operation, the second translation drive cooperates with the first translation drive to drive the movement of the connecting frame, thereby enabling rapid and precise control of the pressure of the clamping plate on the material. For example, the first translation drive is used to control the amount of movement of the clamping plate toward the material clamping side according to the size of the material, while the second translation drive is used to provide a fixed stable amount of movement of the clamping plate in the direction toward the material clamping side. In this way, the clamping plate can be controlled to quickly approach the material according to different material sizes, and the pressure applied to the material can be precisely controlled.

[0028] Reference Figure 1 and Figure 2, a material packing machine includes a first conveying device 100, a posture conversion mechanism, a transfer mechanism, a second conveying device 400, a box turning mechanism and a transfer mechanism, wherein the first conveying device 100 and the second conveying device 400 are mainly used for transferring materials, and can adopt belt conveyors, chain conveyors or roller conveyors; the posture conversion mechanism includes a material rack 210, a clamping plate 231 and a push plate 241, the material rack 210 can rotate along the horizontal axis, one side of the material rack 210 is a material discharge port, the push plate 241 can move on the material rack 210 in a direction close to or away from the material discharge port, the side of the material rack 210 close to the material discharge port is a material clamping side 211, and the clamping plate 231 can move on the material rack 210 in a direction close to or away from the material clamping side 211 The transfer mechanism has a transfer suction cup 300 that can move back and forth between the first conveying device 100 and the material rack 210. For example, the transfer mechanism can select a robotic arm with multiple degrees of freedom of movement, and the robotic arm drives the transfer suction cup 300 to move back and forth between the first conveying device 100 and the material rack 210; the second conveying device 400 is located at the discharge port; the box turning mechanism includes a third conveying device and a first box turning module 500, and the third conveying device is located next to the second conveying device 400. The first box turning module 500 is arranged on the third conveying device, and the first box turning module 500 has a first turning rack for turning the box; the transfer mechanism has a transfer plate 610 that can move back and forth between the conveying end of the second conveying device 400 and the third conveying device.

[0029] As can be seen from the above, the first conveying device 100 is used to input the materials to be boxed. When it moves to the side of the material rack 210, the transfer suction cup 300 in the transfer mechanism moves to the first conveying device 100, sucks up the materials and transfers them to the material rack 210. After the materials are stacked and arranged on the material rack 210, a variety of discharge methods can be used according to different boxing needs. For example, the push plate 241 moves in the direction close to the discharge port to push the materials in the material rack 210 directly to the second conveying device located at the discharge port. 400; or the splint 231 approaches the clamping side 211, pushes the material toward the clamping side 211, adjusts the placement of the material on the material rack 210 first, and then the push plate 241 in the pushing assembly moves toward the direction close to the discharge port, and pushes the material located between the splint 231 and the clamping side 211 to the second conveying device 400 located at the discharge port, so as to adjust the placement of the material and then push it out; or the splint 231 approaches the clamping side 211, presses the material against the clamping side 211, and then The material is clamped between the push plate 241 and the clamping side 211, and then the material rack 210 rotates as a whole until the clamping side 211 faces downward, and then the clamping plate 231 relaxes the clamping of the material, and the push plate 241 in the pushing assembly moves in the direction close to the discharge port, pushing the material to the second conveying device 400 located at the discharge port, so that the material is adjusted to the required placement posture before being pushed out, and the second conveying device 400 conveys the material to the transfer mechanism, and at the box turning mechanism, the third conveying device is used to load the packed box, and during the conveying process, the first turning rack turns the box over and over so that the packaging port of the box faces the transfer mechanism. At this time, the transfer plate 610 in the transfer mechanism approaches the third conveying device, pushing the material in the transfer mechanism into the box, completing the material packing. In this way, the posture of the material can be adjusted first according to different packing requirements, thereby improving the flexibility and convenience of material packaging, and by turning the box over and over, the material can be directly pushed into the box, which greatly improves the packing efficiency.

[0030] In the box turning mechanism, the first turning frame can turn over and lay down the packaging box conveyed on the third conveying device. There are many ways to implement it. In this embodiment, the third conveying device includes a loading conveyor 510, a boxing conveyor 520 and a unloading conveyor 530 arranged in sequence along the left and right directions. The loading conveyor 510 has a plurality of loading rollers 511 arranged at intervals along the left and right directions, and the side horizontally perpendicular to the conveying direction of the boxing conveyor 520 is the feeding side. The first box turning module 500 is located at a position of the loading conveyor 510 close to the boxing conveyor 520, and the first turning frame is located between the two loading rollers 511. The first turning frame can move in the front and back direction and rotate along the axis in the left and right direction. The first turning frame is located near the feeding side and is formed with a first limiting rod 541 extending upward, and the first turning frame is located between the two loading rollers 511 and is formed with a first turning rod 542. The loading conveyor 510, the packing conveyor 520, and the unloading conveyor 530 are arranged in sequence. The packaging boxes can be loaded on the loading conveyor 510, transferred to the packing conveyor 520, and unloaded on the unloading conveyor 530 in sequence. The loading conveyor 510 is provided with a plurality of loading rollers 511 arranged in a spaced relationship along the left and right directions. The plurality of loading rollers 511 rotate to drive the packaging boxes to be transported to the packing conveyor 520, and the interval between two adjacent loading rollers 511 can provide a space for the first turning frame in the first turning module 500 to move. When the packaging box moves to the position where the loading conveyor 510 is close to the packing conveyor 520, the packaging box is located above the first turning rod 542, and the first limiting rod 541 is located on the side of the packaging box close to the feeding side. When the packaging box needs to be turned over, the first turning frame moves in the direction away from the feeding side and rotates along the axis in the left and right directions. At this time, the first turning frame The first stop bar 541 is used to limit the packaging box, and the packaging box is gradually turned over and laid down. After completion, the turned packaging box is transported to the packing conveyor 520. At this time, the material can be loaded into the packaging box at the feeding side to achieve material packing. Then the packing conveyor 520 sends the packaging box to the unloading conveyor 530, and the unloading conveyor 530 moves the packaging box to the next workstation. In this way, the first turning frame is used to turn the packaging box from the bottom side and keep the packaging box limited, effectively preventing damage during the packaging box laying process, and realizing stable and efficient turning and laying of the packaging box. The rotation axis of the first turning frame moves as the packaging box is turned, which can better save the space required for turning and laying the packaging box, and is more practical.

[0031] The conveying end of the second conveying device 400 can also be directly arranged near the feeding side of the boxing conveyor 520. In this case, the transfer mechanism only needs to have a transfer plate 610 for pushing the material into the packaging box. In order to further organize the conveyed material and improve the accuracy of the packaging box, in this embodiment, Figure 3 As shown, the transfer mechanism provides a platform, and the transfer mechanism includes a transfer support plate 620, a first side plate 630 and a transfer drive member 640. The transfer support plate 620 is located between the conveying end of the second conveying device 400 and the feeding side. The first side plate 630 is connected to the side of the transfer support plate 620 away from the second conveying device 400. The first side plate 630 extends above the second conveying device 400. The transfer drive member 640 is arranged above the transfer support plate 620. The transfer drive member 640 drives the transfer drive member 640 connected to the transfer support plate 620. The transfer plate 610, the transfer drive member 640 can drive the transfer plate 610 to move back and forth. The transfer drive member 640 is mainly used to provide the transfer plate 610 with a driving force for reciprocating movement in a straight line direction. A cylinder, a screw rod or a hydraulic cylinder can be used. Since the transfer plate 610 has a large movable stroke, in order to reduce the space occupied by the transfer drive member 640, the transfer drive member 640 can use a motor to drive the synchronous wheel to rotate, and use the synchronous wheel to drive the synchronous belt to rotate, and connect the transfer plate 610 to the synchronous belt. When the synchronous belt rotates, it can drive the transfer plate 610 to move back and forth. After the second conveying device 400 transfers the material to the conveying end, the first side plate 630 limits and blocks the material to position the material, and then the transfer drive 640 provides driving force to the transfer plate 610, driving the transfer plate 610 to move toward the feed side, pushing the material onto the transfer pallet 620. When the packaging box moves to the feed side position, the transfer plate 610 continues to push the material on the transfer pallet 620 into the packaging box, completing the packing of the material, and then the transfer drive 640 drives the transfer plate 610 to return to its original position to prepare for the next transfer of material.

[0032] When the packaging box is transferred to the feeding side, the opening of the packaging box is in an open state. At this time, the cover plate of the packaging box at the open position is easily brought into the packaging box during the process of packing the materials. In order to prevent interference between the materials and the cover plate of the packaging box, in this embodiment, the transfer pallet 620 is connected to the second side plate 650 on the side close to the second conveying device 400, and a connecting rod 660 is connected between the top side of the first side plate 630 and the top side of the second side plate 650. The connecting rod 660, the first side plate 630, and the second side plate 650 are connected. 0 and the transfer pallet 620 to form a hole, the first side panel 630, the second side panel 650, the connecting rod 660 and the transfer pallet 620 are respectively connected with a box supporting plate 670, and multiple box supporting plates 670 are inclined and extended toward the center direction of the hole, and the position of the box conveyor 520 away from the feeding side is connected to a box pushing drive 571, and the box pushing drive 571 is driven by a box pushing member 572, and the box pushing drive 571 can drive the box pushing member 572 to approach or away from the hole. When the packaging box is moved to the hole position, the box pushing driving member 571 drives the box pushing member 572 to approach the hole position and push the packaging box toward the hole position. Because the connecting rod 660, the first side plate 630, the second side plate 650 and the transfer tray 620 are respectively connected with the box supporting plate 670, and multiple box supporting plates 670 are inclined toward the hole position, when the packaging box approaches the hole position, the ends of the multiple box supporting plates 670 can be directly inserted into the packaging box, and as the packaging box gradually moves toward the transfer tray 620, the box supporting plates 670 can gradually open the cover plate at the opening position of the packaging box to the four sides, thereby ensuring that the materials can be smoothly loaded into the packaging box.

[0033] Different materials have different widths. To better position different materials, the first side plate 630 and the second side plate 650 are designed to have adjustable widths. Specifically, a bidirectional screw rod 680 is provided on the bottom side of the transfer tray 620. The bidirectional screw rod 680 has two movable ends that can move toward or away from each other in the left and right directions. The bidirectional screw rod 680 includes a screw with two threaded segments with different thread directions. Two sliders are respectively connected to the two threaded segments. When the screw rod is rotated, the two sliders move toward or away from each other simultaneously on the two threaded segments. The first side plate 630 and the second side plate 650 are respectively connected to the two movable ends, that is, to the two sliders. According to the left and right width requirements of different materials, the two movable ends of the bidirectional screw rod 680 can be adjusted so that the first side plate 630 and the second side plate 650 move toward or away from each other simultaneously. In this way, the distance between the first side plate 630 and the second side plate 650 can be adjusted to better accommodate the size requirements of different materials and improve overall versatility.

[0034] The first box turning module 500 mainly has a driving source that can drive the first turning frame to move in the front-back direction and rotate along the axis in the left-right direction. For example, the first box turning module 500 is equipped with a linear driving source such as a cylinder, an electric screw or a hydraulic cylinder, and a driving motor is installed on the linear driving source. At this time, the driving motor directly drives the first turning frame, and the linear driving source provides the first turning frame with a driving force for moving in the front-back direction, and the driving motor provides the first turning frame with a driving force for rotating along the axis in the left-right direction. In order to reduce the number of driving sources, such as Figure 4As shown, the first box turning module 500 includes a first box turning drive 543, a first slide 544 and a first connecting rod 545. The first box turning drive 543 is connected to the position of the loading conveyor 510 below the loading roller 511. The first box turning drive 543 drives the first slide 544. The first box turning drive 543 can drive the first slide 544 to move in the front and rear directions. The bottom of the first limit rod 541 is rotatably connected to the first slide 544. The two ends of the first connecting rod 545 are respectively rotatably connected to the bottom side of the first turning rod 542 and the side of the loading conveyor 510 away from the feeding side. The rotation axis of the first limit rod 541 and the rotation axes of the two ends of the first connecting rod 545 extend in the left and right directions. After the turned and laid box is transferred out of the loading conveyor 510, the first box-turning driving member 543 drives the first turning frame to move in the direction close to the feeding side, so that the first turning frame is reversed and reset.

[0035] When the packaging box is small, or the width of the first tilting rod 542 and the first limiting rod 541 along the left-right direction is large, sufficient support force can be provided for the packaging box. In this case, the number of first tilting frames can be only one. However, to improve the stability of the packaging box flipping, in this embodiment, multiple first tilting frames are provided at intervals along the left-right direction. When the first slide 544 moves in the front-to-back direction, it can drive multiple first tilting frames to rotate simultaneously. In this case, multiple first tilting frames are used to assist in flipping the packaging box simultaneously, greatly improving the stability of the packaging box flipping and falling.

[0036] To further enhance the stability of the first slide 544, in this embodiment, a first sliding shaft extending in the front-to-rear direction is connected to the loading conveyor 510 below the loading roller 511. The first slide 544 is slidably connected to the first sliding shaft. The first slide 544 slides back and forth along the first sliding shaft, and the sliding engagement between the first sliding shaft and the first sliding shaft enhances the stability of the first slide 544. In particular, when multiple first tilting frames are mounted on the first slide 544, the first sliding shaft balances the load on the first slide 544, preventing the first tilting frames from shifting and interfering with the loading roller 511.

[0037] The packing conveyor 520 can be a roller conveyor or a chain conveyor, etc. In order to improve the accuracy of the packing conveyor 520 in conveying the packaging boxes, a structure for blocking and limiting the packaging boxes can be installed in the packing conveyor 520. Specifically, the packing conveyor 520 includes two conveyor belts spaced apart in the front-to-back direction, and a fixed frame 551 is provided between the two conveyor belts. Figure 5 As shown, a connecting seat 552 is provided in the fixing frame 551, and a transmission block 553 and a telescopic driving member 554 are rotatably connected to the connecting seat 552. One end of the telescopic driving member 554 is rotatably connected to the eccentric position at the bottom of the transmission block 553. The rotation axis of the transmission block 553 and the rotation axes of both ends of the telescopic driving member 554 extend in the front-to-back direction. A baffle 556 is connected to the top side of the transmission block 553. When the packaging box moves to the two conveyor belts, the two conveyor belts rotate synchronously to realize the transfer of the packaging box on the packing conveyor 520. When the packaging box is moved into place, the two conveyor belts stop working, and the baffle 556 on the top side of the transmission block 553 is used to block and limit the packaging box, so that the packaging box can be moved into place accurately, and then the products to be packed are packed into the packaging box. After completion, the telescopic drive member 554 drives the transmission block 553 to rotate, causing the baffle 556 to rotate and descend, and the two conveyor belts continue to work to send the completed packed packaging box to the unloading conveyor 530, so that the packaging box can be transported into, positioned, and sent out on the packing conveyor 520.

[0038] To facilitate positioning of boxes of varying sizes, in this embodiment, an adjustment screw 555 is provided on the fixing frame 551. The adjustment screw 555 is in transmission connection with the connecting seat 552 and can move the connecting seat 552 in the left-right direction. The adjustment screw 555 can be a hand-cranked screw or an electric screw. Depending on the size of the boxes, the position in which the boxes need to be positioned on the packing conveyor 520 will also be different. In this case, the position of the connecting seat 552 can be adjusted by adjusting the screw 555 to change the left-right position of the baffle 556 according to different usage needs, thereby flexibly and conveniently adjusting the positioning of the boxes.

[0039] After the material is packed, the packaging box can be turned back to the right side manually, or the packaging box can be turned over mechanically. Specifically, the transfer mechanism also includes a second turning box module 560, and the unloading conveyor 530 is provided with multiple unloading rollers 531 at intervals along the left and right directions. The second turning box module 560 is located at a position where the unloading conveyor 530 is close to the packaging conveyor 520. The second turning box module 560 is provided with a second turning frame between the two unloading rollers 531. The second turning frame can move in the front and back directions and rotate along the axis in the left and right directions. The second turning frame is located at a position away from the feeding side and is formed with a second limit rod extending upward. The second turning frame is located between the two loading rollers 511 and is formed with a second turning rod. In actual application, the unloading conveyor 530 can be a roller conveyor with a motor inside. The motor drives the multiple unloading rollers 531 to rotate through a chain or synchronous belt drive, thereby realizing the outward delivery of the packaging boxes with completed product packing. The unloading conveyor 530 is provided with a plurality of unloading rollers 531 arranged at intervals along the left and right directions, and the plurality of unloading rollers 531 rotate to realize sending out the packaged carton, and the interval space between two adjacent unloading rollers 531 can provide space for the second turning frame in the second turning box module 560 to move. When the carton moves to the position where the unloading conveyor 530 is close to the box packing conveyor 520, the carton is located above the second turning rod, and the second limit rod is located on the side of the carton away from the feeding side. When the carton needs to be turned over, the second turning frame moves toward the feeding side and rotates along the axis in the left and right directions. At this time, the second turning rod rotates upward and protrudes from the unloading roller 531, lifting the position of the carton close to the feeding side, so that the carton slides along the second turning rod to one side of the second limit rod, and the carton is limited by the second limit rod, gradually realizing the turning back to the right side of the carton. After completion, the opening of the carton faces upward, and the unloading roller 531 continues to move to convey the turned carton to the next workstation.

[0040] In actual application, the second box turning module 560 can adopt the same structure as the first box turning module 500. Specifically, the second box turning module 560 includes a second box turning drive, a second slide and a second connecting rod. The second box turning drive is connected to the position of the unloading conveyor 530 below the unloading roller 531. The second box turning drive drives the second slide. The second box turning drive can drive the second slide to move in the front and back directions. The bottom of the second limit rod is rotatably connected to the second slide. The two ends of the second connecting rod are respectively rotatably connected to the bottom side of the second turning rod and the side of the unloading conveyor 530 close to the feeding side. The rotation axis of the second limit rod and the rotation axes at both ends of the second connecting rod extend in the left and right directions. The second box-turning drive can provide a driving force for the second turning frame to move in the front-to-back direction. When the package box enters the unloading conveyor 530, the second slide is located at a position away from the feed side. When the package box needs to be turned back to the right side, the second box-turning drive drives the second slide to move in the direction close to the feed side. Since the second turning rod is connected to the position of the unloading conveyor 530 away from the feed side by a second connecting rod, the second turning rod moves in the direction away from the feed side while rotating upward, and drives the second limit rod to rotate downward as well. In this way, the second turning frame can turn the package box back to the right side and realize the synchronous movement of the rotation axis of the second turning frame, reducing the space required in the front-to-back direction. After the package box that has been turned back to the right side is transferred out of the unloading conveyor 530, the second box-turning drive drives the second turning frame to move in the direction away from the feed side, so that the second turning frame is reversed and reset.

[0041] The posture conversion mechanism is mainly used to adjust the posture of the material. Figure 6As shown, the posture conversion mechanism includes a rotary drive member 222, a first translation drive member 232, a connecting frame 233 and a push-material translation drive 242. The rotary drive member 222 can be a rotary cylinder or a drive motor. The rotary drive member 222 drives the material rack 210, and the rotary drive member 222 can drive the material rack 210 to rotate. The first translation drive member 232 is connected to the material rack 210, and the first translation drive member 232 drives the connecting frame 233. The first translation drive member 232 can drive the clamping plate 231 to move closer to or away from the clamping side 211. The clamping plate 231 is arranged on the connecting frame 233. The push-material translation drive 242 is connected to the material rack 210, and the push-material translation drive 242 drives the push plate 241, and the push-material translation drive 242 drives the push plate 241 to move closer to or away from the discharge port. The rotating drive member 222 provides a rotating driving force for the material rack 210, which can drive the material rack 210 to rotate along the horizontal axis, thereby turning the material on the material rack 210 to adjust the material placement. For example, when the material is loaded onto the material rack 210, it is in a horizontal state. As the material rack 210 rotates, the material rack 210 can be turned to a vertical state. The first translation drive member 232 provides a translation force for the clamping plate 231 to move closer to or away from the clamping side 211. The connecting frame 233 can extend the installation position of the clamping plate 231 so that the clamping plate 231 can be directly opposite to the middle position of the clamping side 211, thereby better acting on the material. When working, the first translation drive member 23 The connecting frame 233 drives the clamping plate 231 toward the material clamping side 211 to clamp the material, or the first translation driving member 232 drives the clamping plate 231 away from the material clamping side 211 through the connecting frame 233 to release the clamping of the material. The pushing translation driving member 242 provides a driving force for the push plate 241 to move toward or away from the discharge port. When the material needs to be pushed to the next workstation, the pushing translation driving member 242 drives the push plate 241 toward the discharge port, and the push plate 241 is used to push the material to the discharge port. Then, the pushing translation driving member 242 drives the push plate 241 away from the discharge port to reset and prepare for the next material pushing.

[0042] In the above embodiment, only the first translation drive member 232 can provide the driving force for the clamping plate 231. Since the clamping force required for clamping the material is different depending on the size of the space, a second translation drive member 234 is connected between the connecting frame 233 and the clamping plate 231. The second translation drive member 234 can drive the clamping plate 231 to move closer to or away from the clamping side 211. The second translation drive member 234 further provides a driving force for the splint 231 to move in the direction of approaching or moving away from the clamping side 211. During operation, it cooperates with the first translation drive member 232 to drive the movement of the connecting frame 233, so as to realize fast and precise control of the pressure of the splint 231 on the material. For example, the first translation drive member 232 is used to control the amount of movement of the splint 231 toward the clamping side 211 according to the size of the material, and the second translation drive member 234 is used to provide the splint 231 with a fixed stable amount in the direction close to the clamping side 211. In this way, the splint 231 can be controlled to quickly approach the material according to different material sizes, and the pressure applied to the material can be precisely controlled.

[0043] In actual applications, the first translation drive member 232 and the second translation drive member 234 are both used to provide driving force for reciprocating movement in a straight line direction. For example, a cylinder, a screw rod or a hydraulic cylinder can be selected. When the first translation drive member 232 and the second translation drive member 234 are used in combination, the first translation drive member 232 can be selected as a screw rod and the second translation drive member 234 can be selected as a cylinder, which can realize the precise and rapid movement of the splint 231.

[0044] The first box turning driver 543, the second box turning driver, the box pushing driver 571, and the telescopic driver 554 are all used to provide driving force for reciprocating motion in a linear direction, and their structural forms include various types, such as cylinders, screw rods, or hydraulic cylinders.

[0045] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
