Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of packaging devices, and in particular relates to a cartoning machine. Background Technology
[0002] In modern industrial production, automated packaging is a key element in improving production efficiency and reducing labor costs. As the core equipment of the packaging production line, the technological development of cartoning machines directly impacts packaging quality and production efficiency. Traditional cartoning processes primarily rely on manual operation, manually arranging folded, flat cardboard boxes into a three-dimensional structure before placing the items to be packaged inside. This method is not only inefficient and labor-intensive, but also prone to inconsistent packaging precision due to human factors, making it difficult to meet the demands of large-scale industrial production.
[0003] While existing automated cartoning technologies have achieved carton forming and filling to some extent, they still have many shortcomings. Some cartoning machines use robotic arms to simulate manual actions for carton arrangement, but these are complex in structure and expensive. Another type of cartoning machine, based on the principle of vacuum adsorption, can complete the initial unfolding of the carton, but during the three-dimensional forming process, uneven adsorption forces often lead to irregular folding angles, affecting subsequent filling and product protection. Therefore, there is an urgent need to develop a new cartoning machine technology that is compact, adaptable, and can efficiently complete three-dimensional carton forming and precise filling.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0033] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0034] In one embodiment of this utility model, such as Figures 1-2As shown, a cartoning machine is provided, including a carton feeding device 10, a carton transfer device 20, a conveying device 30, and an article feeding device 40. Multiple cartons are stacked horizontally in sequence on the carton feeding device 10. The carton transfer device 20 is used to pick up cartons from the carton feeding device 10 and transfer them to the next station. The conveying device 30 includes a conveying mechanism 31 and a shaping mechanism 32. The shaping mechanism 32 is disposed on the conveying mechanism 31 and can move with the conveying mechanism 31. The shaping mechanism 32 receives cartons transferred by the carton transfer device 20 and is used to shape the cartons, changing them from a folded shape to a three-dimensional shape, forming a cavity inside the cartons, and at least one end of the cartons has an opening communicating with the cavity. The article feeding device 40 is located beside the conveying device 30 and is used to push articles into the cavity of the shaped cartons.
[0035] The operator places multiple folded cardboard boxes horizontally on the cardboard box feeding device 10 to complete the initial feeding preparation. The picking component (such as a vacuum suction cup or mechanical gripper) of the cardboard box transfer device 20 moves to the cardboard box feeding device 10, adsorbs or clamps the top cardboard box, and then transfers the cardboard box to the shaping mechanism 32 of the conveying device 30 according to a preset path. The conveying mechanism 31 drives the shaping mechanism 32 to move. When the cardboard box is transferred to the shaping mechanism 32, the shaping mechanism 32 applies force to the cardboard box, unfolds the folded cardboard box and shapes it into a three-dimensional shape, so that the inside of the cardboard box forms a cavity, with at least one end open, to facilitate the filling of items. After the cardboard box is shaped, the item feeding device 40 arranges the items to be loaded. When the shaped cardboard box moves with the conveying mechanism 31 to the discharge port of the item feeding device 40, the pushing component of the item feeding device 40 quickly and accurately pushes the items into the cavity of the cardboard box, completing the boxing operation.
[0036] In this embodiment, the shaping mechanism 32 includes a plurality of shaping blocks 33 sequentially arranged on the conveying mechanism 31; each shaping block 33 has a shaping groove 34, and the distance between the opposite side walls of the shaping groove 34 can be fixed, or the width of the shaping groove 34 can gradually decrease along the direction closer to the conveying mechanism 31. Specifically, when the paper box transfer device 20 transfers the folded paper box onto the conveying mechanism 31, the paper box moves forward with the conveying mechanism 31. The paper box enters the shaping groove 34, and the paper box unfolds into a three-dimensional paper box under the force of the side walls of the shaping groove 34. With the gradually decreasing width of the shaping groove 34, as the paper box moves downward, the shaping groove 34 applies an inward squeezing force to the sides of the paper box, and the sides of the paper box are gradually folded and squeezed into a three-dimensional shape, forming a cavity inside the paper box, with at least one end open. For example, in the initial state, the sides of the cardboard box are folded. When it enters the wider shaping groove 34, the sides begin to unfold initially. As it passes through the gradually narrowing shaping groove 34, the sides are further squeezed and folded, eventually forming a regular three-dimensional box structure, which is ready for subsequent item filling.
[0037] In this embodiment, the shaping block 33 includes two opposing shaping pieces 331, with one side of each shaping piece 331 folded inward to form a bent portion 332. Specifically, the angle between the bent portion 332 and the shaping piece 331 is 90 degrees. The surface of the bent portion 332 can increase the contact area with the cardboard box, thus better helping the cardboard box to unfold and be fixed.
[0038] Furthermore, each of the two shaping plates 331 has a bevel on one side; specifically, the angle of inclination (the angle with the vertical direction) of the bevel is 15°-25°. When the cardboard box enters the shaping groove 34, its two side wing plates contact the starting end of the bevel. As the conveying mechanism 31 pushes, the wing plates slide upward along the bevel and gradually unfold, eventually forming a standard cubic structure.
[0039] In this embodiment, a pallet 60 is provided on the conveying mechanism 31. The pallet 60 is located beside the shaping sheet 331 and close to the bottom of the shaping sheet 331. Specifically, after the paper box is shaped, the bottom of the paper box contacts the pallet 60, providing support to the paper box.
[0040] In this embodiment, the shaping piece 331 is provided with a connecting hole 334 for fixing to the chain of the conveying mechanism 31. Specifically, when the drive device (such as a motor) of the conveying mechanism 31 is started, the motor drives the chain to move through transmission components (such as belts and gears). Since the shaping piece 331 is fixed to the chain through the connecting hole 334, the movement of the chain will drive the shaping piece 331 to move synchronously. When the paper box transfer device 20 places the folded paper box on the conveying mechanism 31, the paper box moves forward with the conveyor belt of the conveying mechanism 31. The shaping piece 331 is directly fixed to the chain of the conveying mechanism 31 through the connecting hole 334, reducing additional mounting brackets and complex connection structures, making the overall structure of the shaping mechanism 32 more compact and space-saving. At the same time, this connection method facilitates the installation and removal of the shaping piece 331. When the shaping piece 331 is worn or needs to be replaced, the locking component can be loosened to quickly replace the shaping piece 331, reducing the maintenance difficulty and cost of the equipment and improving the maintainability of the equipment.
[0041] In this embodiment, the carton transfer device 20 includes a drive mechanism 21, a first transfer mechanism 22, and a second transfer mechanism 23. The drive mechanism 21 drives the first transfer mechanism 22 and the second transfer mechanism 23. The first transfer mechanism 22 is located close to the carton feeding device 10 and is used to absorb the cartons on the carton feeding device 10. The second transfer mechanism 23 is located below the first transfer mechanism 22 and is used to receive the cartons from the first transfer mechanism 22. Specifically, the vertically staggered motion trajectory design of the first transfer mechanism 22 and the second transfer mechanism 23 reduces the projected area of the transfer device in the XY plane, making the structure more compact.
[0042] In this embodiment, both the first transfer mechanism 22 and the second transfer mechanism 23 are equipped with adsorption components 24, which are connected to a negative pressure device to generate adsorption force. Specifically, the negative pressure generated by the negative pressure device adsorbs the paper box, ensuring that the paper box is stable and does not easily fall off during the movement process.
[0043] In this embodiment, a folding device 50 is also included, located beside the conveying device 30. The folding device 50 is used to fold and shape the paper box to close both ends of the paper box. Specifically, when the conveying device 30 conveys the shaped paper box to the designated position, the end of the paper box reaches the front of the push plate of the folding device 50. At this time, the photoelectric sensor of the conveying device 30 detects the paper box's arrival signal and transmits the signal to the PLC control system. The control system then starts the power source of the folding device 50 and folds and closes the end of the paper box.
[0044] In this embodiment, the item feeding device 40 includes an item feeding conveyor line 41 and an item feeding robot 42. The item feeding conveyor line 41 is arranged parallel to the conveying mechanism 31. The item feeding robot 42 is located above the item feeding conveyor line 41 and is used to pick up the items on the item feeding conveyor line 41 and transfer them into the shaped cardboard box. Specifically, when an item is placed on the item feeding conveyor line 41, the drive motor of the conveyor line starts, driving the transmission roller to make the conveyor line run and transport the item to the discharge end. During the conveying process, the item feeding conveyor line 41 can be equipped with a photoelectric sensor to detect the position and quantity of the items in real time, ensuring that the items are transported in an orderly manner. When the item reaches the discharge end of the item feeding conveyor line 41, the photoelectric sensor detects the item arrival signal and transmits the signal to the control system of the item feeding device 40. The control system then controls the item feeding robot 42 to move above the item. According to the type of item, the robot picks up the item and completes the picking action. After picking up the item, the item feeding robot 42 moves to the side of the shaped cardboard box on the conveying mechanism 31 according to a preset motion trajectory. At this point, the conveyor 30 has transported the cardboard box to the designated loading position. The robotic arm accurately pushes the item into the cavity of the cardboard box, then releases the item, completing the loading process. After loading is complete, the robotic arm returns to its initial position, waiting for the next pickup command. The entire process is repeated cyclically.
[0045] In this embodiment, the conveying end of the carton feeding device 10 is provided with a downwardly inclined conveying section 11, and a baffle plate 12 is provided at the end of the conveying section 11, located above the conveying section 11. Specifically, when multiple cartons are stacked horizontally on the carton feeding device 10 in sequence, the cartons move forward under the drive of the device. When the cartons reach the conveying section 11, due to the downward inclination of the conveying section 11, the cartons slide downward along the conveying section 11 under their own weight. As the cartons slide down, when the front end of the cartons contacts the baffle plate 12, the baffle plate 12 generates a blocking force on the cartons, stopping the cartons from sliding down and positioning them at the end of the conveying section 11. At this time, the carton transfer device 20 moves to this position, its picking component picks up the positioned cartons, and then transfers the cartons to the next station. After the cardboard box transfer device 20 removes a cardboard box, the subsequent cardboard boxes continue to slide down under the action of gravity to fill the empty space, and are then blocked and positioned again by the baffle plate 12. This cycle is repeated to realize the continuous feeding process of cardboard boxes. By adjusting the angle and distance between the baffle plate 12 and the conveyor section 11, the feeding requirements of cardboard boxes of different sizes and thicknesses can be adapted to ensure the accuracy and stability of feeding.
[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
