Description

Technical Field

[0001] This application belongs to the field of cartoning equipment, and in particular relates to a top-opening cartoning machine. Background Technology

[0002] Cartoning machines are automated devices widely used in the food and pharmaceutical industries to unfold and shape flat box blanks and then fill them with products. Traditional cartoning machines typically use a conveyor belt to transport the box blanks to the forming station, where a mechanical mechanism unfolds the box and loads the product. However, existing equipment is prone to irregular folding due to blank positioning deviations during the box forming stage, and in the final forming stage, inaccurate coordination between the material handling mechanism and the conveyor chain often leads to box jamming, deformation, or displacement. These defects not only reduce the forming pass rate but also severely restrict cartoning efficiency due to frequent downtime for adjustments. Therefore, it is necessary to solve the above-mentioned technical problems. Summary of the Invention

[0003] The purpose of this application is to provide a top-opening cartoning machine to solve the technical problem of low carton forming efficiency in existing cartoning machines.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a top-opening carton filling machine, comprising:

[0005] frame;

[0006] A conveyor belt, connected to the frame, is used to transport the box blanks;

[0007] The conveyor chain is perpendicular to and spaced apart from the conveyor belt;

[0008] The preformed assembly includes a connecting plate connected between the conveyor belt and the conveyor chain, and side plates perpendicular to the connecting plate and capable of moving closer to or further away from each other. The connecting plate is connected to the end of the conveyor belt, and the side plates cooperate with the connecting plate to form a feeding channel located between the conveyor belt and the conveyor chain.

[0009] The final forming assembly includes card plates spaced apart on the conveyor chain and suction cups movably mounted on the frame and capable of picking up material from the conveyor belt by movement. The card plates are parallel to the side plates and a predetermined spacing for forming a target box is formed between the card plates. The movement path of the suction cups is perpendicular to the conveyor chain and can sequentially pass through the spacing between the card plates and the spacing between the side plates.

[0010] Optionally, the preforming assembly further includes a conveyor belt shaft, a feeding cylinder, a ratchet, and a rocker arm;

[0011] The conveyor belt shaft is connected to both ends of the conveyor belt and is used to support the conveyor belt. The feeding cylinder is connected to the frame. The ratchet is coaxially connected to the conveyor belt shaft. One end of the rocker arm is connected to the ratchet, and the other end is hinged to the output end of the feeding cylinder.

[0012] Optionally, the preforming assembly further includes a guide rod parallel to the conveyor belt;

[0013] The guide rod is spaced apart from the feeding surface of the conveyor belt and is used to provide movement guidance for the box blank.

[0014] Optionally, the top-opening cartoning machine further includes a drive cylinder with its output direction perpendicular to the conveyor belt, and at least one of the side plates is connected to the drive cylinder and can be driven by the drive cylinder.

[0015] Optionally, the guide rods are arranged at intervals in a direction perpendicular to the feeding surface of the conveyor belt.

[0016] Optionally, the final forming assembly further includes a servo motor, a synchronous belt, and a box-pulling head;

[0017] The servo motor is mounted on the frame, the synchronous belt is connected to the power end of the servo motor and can be driven by the servo motor to move back and forth, the box puller is connected to the synchronous belt and the suction cup is mounted on the box puller.

[0018] Optionally, the final forming assembly further includes a linear guide parallel to the conveyor belt and a sliding seat slidably connected to the linear guide;

[0019] The pull box head is connected to the sliding seat and then connected to the timing belt through the sliding seat.

[0020] Optionally, the final forming assembly further includes a tie rod parallel to the conveyor belt;

[0021] The two ends of the pull rod are respectively connected to the pull box head and the sliding seat.

[0022] Optionally, a plurality of evenly distributed perforations are formed on the card plate.

[0023] Optionally, the final forming assembly further includes a guide rail parallel to the conveyor chain;

[0024] The guide rail passes through the hollowed-out holes on both sides and is used to provide movement guidance for the target box.

[0025] The beneficial effects of the top-opening carton filling machine provided in this application are as follows: Compared with the prior art, in the top-opening carton filling machine provided in this application, after the box blank is horizontally conveyed to the end by the conveyor belt, the suction cup moves forward to pick up the last box blank and pulls it back towards the clamping plate. The box blank enters the feeding channel formed by the connecting plate and the side plate through the connecting plate. At this time, the side plates, which can be close to or far apart from each other, cooperate with the connecting plate to initially constrain the blank to form a pre-formed structure. Subsequently, the suction cup continues to move back along a path perpendicular to the conveyor chain, continuing to pick up the pre-formed blank so that it continues to move and reaches the predetermined distance between the clamping plates on the conveyor chain, so that the blank unfolds into the target box within the clamping plate interval. The suction cup is released, and at this time, the target box... The box body moves forward with the conveyor chain within the predetermined gap between the pallets and enters the guide area of ​​the guide rail. Since the suction cup stops at the same level as the guide rail surface, the edge of the suction cup also provides auxiliary support to the corresponding side wall of the target box before it enters the guide area of ​​the guide rail, preventing the target box from springing back and deforming. The pre-forming components effectively prevent positioning offset and folding deformation during the forming process by pre-regulating and constraining the blank, significantly improving the accuracy and stability of the box forming shape. At the same time, the continuous action of the suction cup passing parallel through the gap between the side plate and the pallet shortens the transfer path, making the box forming process seamless. Ultimately, this greatly improves the box forming efficiency of the top-opening cartoning machine in this application, which is far superior to the prior art. Attached Figure Description

[0035] Please see Figures 1 to 3 The present application provides a top-opening carton filling machine according to an embodiment. The top-opening carton filling machine includes a frame 101, a conveyor belt 102, a conveyor chain 103, a pre-forming assembly, and a final forming assembly. Wherein:

[0036] The conveyor belt 102 is connected to the frame 101 and is used to transport the box blank; the conveyor chain 103 is perpendicular to the conveyor belt 102 and spaced apart; the preforming assembly includes a connecting plate 104 connected between the conveyor belt 102 and the conveyor chain 103, and also includes side plates 105 perpendicular to the connecting plate 104 and capable of moving closer or further apart from each other. The connecting plate 104 is connected to the end of the conveyor belt 102, and the side plates 105 cooperate with the connecting plate 104 to form a feeding channel 106 located between the conveyor belt 102 and the conveyor chain 103; the final forming assembly includes clamping plates 107 spaced apart on the conveyor chain 103, and also includes a suction cup 108 movably mounted on the frame 101 and capable of picking up material from the conveyor belt 102 by movement. The clamping plates 107 are parallel to the side plates 105 and a predetermined spacing for forming the target box is formed between the clamping plates 107. The moving path of the suction cup 108 is perpendicular to the conveyor chain 103 and can sequentially pass through the gaps between the clamping plates 107 and the gaps between the side plates 105. It is understood that the boxing efficiency can be further improved by connecting multiple sets of pallets 107 on the conveyor chain 103; in this embodiment, it also includes a feeding robot 600, several sets of paper feeding assemblies 200, a lid closing assembly 300, a pusher 400 located at the end of the conveyor chain 103, and a finished product conveyor belt 500 arranged parallel to the side of the end of the conveyor chain 103, arranged in sequence on the frame 1 along the travel direction of the conveyor chain 103; wherein, the feeding robot 600 is used to load materials into the unfolded target box, and the paper feeding assembly 200 is used to feed materials into the target box. The instruction manual is included. The cover closing assembly 300 is used to close the cover of the target box containing the material. The pusher 400 is pushed by a linear drive device to push the target box from the platen 107 on the conveyor chain 103 onto the finished product conveyor belt 500. That is, the moving direction of the pusher 400 is perpendicular to the traveling direction of the conveyor chain 103. When the pusher 400 moves, the conveyor chain 103 will pause. The feeding robot 600, several sets of paper feeding assemblies 200, the cover closing assembly 300, the pusher 400, and the finished product conveyor belt 500 can adopt existing technology.

[0037] According to the structure provided in this embodiment, in the top-opening carton filling machine provided in this embodiment, after the box blank is horizontally conveyed to the end by the conveyor belt 102, the suction cup 108 moves forward to pick up the last box blank and pulls it back towards the clamping plate 107. The box blank enters the feeding channel 106 formed by the connecting plate 104 and the side plate 105 through the connecting plate 104. At this time, the side plates 105, which can move closer or further away from each other, cooperate with the connecting plate 104 to initially constrain the blank and form a pre-formed structure. Then, the suction cup 108 continues to move back along a path perpendicular to the conveyor chain 103, continues to pick up the pre-formed blank and makes it continue to move and reach the predetermined distance between the clamping plates 107 on the conveyor chain 103, so that the blank unfolds into the target box within the interval of the clamping plates 107. The suction cup is released. At this time, the target box is stuck in the predetermined distance between the clamping plates and moves forward with the conveyor chain and enters the guide area of ​​the guide rail 122. The suction cup 108 stops flush with the guide surface of the guide rail 122. Therefore, before the target carton enters the guide area of ​​the guide rail 122, the edge of the suction cup 108 also provides auxiliary support to the corresponding side wall of the target carton, preventing the target carton from springing back and deforming. The pre-forming components effectively prevent positioning offset and folding deformation during the forming process by pre-regulating and constraining the blank, significantly improving the accuracy and stability of the carton forming shape. At the same time, the continuous action of the suction cup 108 passing parallel through the side plate 105 and the cardboard plate 107 shortens the transfer path, making the carton forming process seamless. Ultimately, this greatly improves the carton forming efficiency of the top-opening carton boxing machine in this embodiment, which is far superior to the prior art. Here, it is understood that when the suction cup 108 moves, the conveyor chain 103 will pause. It is understood that this embodiment is applicable to carton types that do not require the bottom to be closed, that is, carton types whose bottom is already closed when the carton is unfolded into the target carton.

[0038] In another embodiment of this application, please refer to Figures 1 to 3 The preforming assembly also includes a conveyor belt shaft 109, a feeding cylinder 110, a ratchet 111, and a rocker arm 112. The conveyor belt shaft 109 is connected to both ends of the conveyor belt 102 and is used to support the conveyor belt 102. The feeding cylinder 110 is connected to the frame 101. The ratchet 111 is coaxially connected to the conveyor belt shaft 109. One end of the rocker arm 112 is connected to the ratchet 111, and the other end is hinged to the output end of the feeding cylinder 110. This allows the blank conveying rhythm to dynamically match the position of the clamping plate 107, eliminating the clamping deviation caused by traditional continuous conveying, thereby further improving the box forming efficiency of the top-opening box-packing machine in this embodiment.

[0039] In another embodiment of this application, please refer to Figures 1 to 3The preforming assembly also includes guide rods 113 parallel to the conveyor belt 102; the guide rods 113 are spaced apart from the feeding surface of the conveyor belt 102 and are used to provide movement guidance for the box blank. According to the structure provided in this embodiment, when the box blank moves on the surface of the conveyor belt 102, the parallel guide rods 113 are spaced apart from the feeding surface of the conveyor belt 102, forming a guiding space covering the blank, limiting the vertical displacement and lateral sway of the blank during the conveying process; when the blank is moved step by step with the conveyor belt 102, the guide rods 113 continuously constrain its movement trajectory, ensuring that the blank always arrives accurately at the connecting plate 104 at the end of the conveyor belt 102 along a straight path, which is beneficial to further improve the box forming efficiency of the top-opening box-packing machine in this embodiment.

[0040] In another embodiment of this application, please refer to Figures 1 to 3 The top-opening carton filling machine also includes a drive cylinder 114 whose output direction is perpendicular to the conveyor belt 102. At least one side plate 105 is connected to the drive cylinder 114 and can be driven by the drive cylinder 114. According to the structure provided in this embodiment, the drive cylinder 114 connected to the side plate 105 can stably drive the two side plates 105 to move closer or further apart, which is beneficial to further improve the box forming efficiency of the top-opening carton filling machine in this embodiment.

[0041] In another embodiment of this application, please refer to Figures 1 to 3 The guide rods 113 are spaced apart in a direction perpendicular to the feeding surface of the conveyor belt 102. According to the structure provided in this embodiment, the multi-layer guide rods 113 form a stepped guide barrier above the blank, which can simultaneously suppress the vibration offset and posture fluctuation of different areas of the box blank during the conveying process, thereby further improving the box forming efficiency of the top-opening box-packing machine in this embodiment.

[0042] In another embodiment of this application, please refer to Figures 1 to 3The final forming assembly also includes a servo motor 115, a synchronous belt 116, and a box-pulling head 117. The servo motor 115 is mounted on the frame 101, the synchronous belt 116 is connected to the power end of the servo motor 115 and can be driven by the servo motor 115 to move back and forth, and the box-pulling head 117 is connected to the synchronous belt 116 and a suction cup 108 is mounted on the box-pulling head 117. According to the structure provided in this embodiment, the servo motor 115 precisely controls the reciprocating trajectory of the box-pulling head 117 through the synchronous belt 116, so that the suction cup 108 runs at high speed and stably along a path perpendicular to the conveyor chain 103 and stops precisely at a preset position. This ensures that after the suction cup 108 sequentially passes through the side plates 105 to pick up the material, it seamlessly transfers the blank to the interval of the clamping plate 107 for final forming. Furthermore, the released suction cup 108 provides auxiliary support to the target box at the stop position, ensuring the complete forming of the target box. This helps to eliminate the positioning jitter and speed waves present in traditional pneumatic drives. This movement further improves the box forming efficiency of the top-opening box-packing machine in this embodiment. It can be understood that the optimal stopping position of the suction cup 108 is that after the suction cup 108 stops, its edge is flush with the guide surface of the guide rail 122. This way, it will not interfere with the operation of the pallet 107 with the conveyor chain 103, and it will also provide effective sliding support for the target box. The principle is that after the suction cup 108 is released, it no longer sucks the box, but the suction cup 108 itself still has a certain rigidity to support the target box. When the pallet 107 moves the target box, the side wall of the target box can smoothly slide over the edge of the suction cup 108.

[0043] In another embodiment of this application, please refer to Figures 1 to 3 The final forming assembly also includes a linear guide 118 parallel to the conveyor belt 102 and a sliding seat 119 slidably connected to the linear guide 118; the box-pulling head 117 is connected to the sliding seat 119 and connected to the synchronous belt 116 through the sliding seat 119. According to the structure provided in this embodiment, the linear guide 118 can provide a high-rigidity linear guide for the sliding seat 119, so that the box-pulling head 117 driven by the synchronous belt 116 always moves along a precise path parallel to the conveyor belt 102, ensuring that the suction cup 108 has no radial offset when passing through the gap between the side plate 105 and the clamping plate 107. This helps to eliminate the trajectory deviation of the suction cup 108 in the process of transferring the blank, thereby further improving the box forming efficiency of the top-opening box-packing machine in this embodiment.

[0044] In another embodiment of this application, please refer to Figures 1 to 3The final forming assembly also includes a pull rod 120 parallel to the conveyor belt 102; both ends of the pull rod 120 are connected to the box-pulling head 117 and the sliding seat 119, respectively. According to the structure provided in this embodiment, the box-pulling head 117 is pulled by the synchronous belt 116 through the pull rod 120, which can significantly shorten the effective driving length of the synchronous belt 116. This not only helps to reduce the positioning delay and trajectory deviation caused by the elastic deformation of the synchronous belt 116, but also further improves the box forming efficiency of the top-opening box-packing machine in this embodiment.

[0045] In another embodiment of this application, please refer to Figures 1 to 3 A plurality of evenly distributed perforated holes 121 are formed on the pallet 107. According to the structure provided in this embodiment, the evenly distributed perforated holes 121 can significantly reduce the overall weight of the pallet 107 and reduce its wind resistance area, thereby reducing the inertial load and airflow disturbance when the conveyor chain 103 drives the pallet 107 to move, which is beneficial to further improve the box forming efficiency of the top-opening box-packing machine in this embodiment.

[0046] In another embodiment of this application, please refer to Figures 1 to 3 The final forming component also includes a guide rail 122 parallel to the conveyor chain 103; the guide rail 122 passes through the hollow holes 121 with openings on both sides and is used to provide movement guidance for the target box. According to the structure provided in this embodiment, the guide rail 122 passing through the hollow holes 121 of the clamping plate 107 can provide rigid linear constraints on both sides of the target box, so that the box cannot sway laterally when it is moved within the interval of the clamping plate 107, which can effectively prevent the target box from leaving the interval of the clamping plate 107 during the conveying process. It should be noted that in the specific implementation process, the position of the guide rail 122 needs to be flexibly adjusted to avoid blocking the transfer process of the box blank from the feeding channel 106 to the clamping plate 107; it is understood that the guide rail 122 is parallel to the travel direction of the conveyor chain 103, and the distance from the opening into the hollow hole 121 along the vertical direction of the conveyor chain 103 can be adjusted by a mechanical adjustment support component such as a support rod (not shown) installed on the frame 1, so as to adapt to target boxes of different sizes.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
