Description

Technical Field

[0001] This utility model belongs to the field of automatic carton sealing machines, and in particular relates to a linear layout fully automatic carton sealing machine. Background Technology

[0002] Currently, most carton sealing machines on the market adopt a T-shaped or square layout. This layout occupies workshop space in multiple dimensions, making it difficult to meet the specific spatial layout requirements of some production workshops. Furthermore, in the carton blank feeding stage, existing carton sealing machines require manual transfer of carton blanks from pallets to the material storage area, which is labor-intensive and has a low degree of automation. In addition, during the packing and sealing process of boxed products, some steps rely on manual operation, and production efficiency needs improvement. Therefore, there is an urgent need for a carton sealing machine with a more rational layout and a higher degree of automation to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a linear layout fully automatic carton sealing machine, aiming to solve the problems existing in the background art. To achieve this purpose, the technical solution adopted by this utility model is:

[0004] A linear layout fully automatic carton sealing machine includes a frame, a storage assembly, a feeding assembly, a stacking assembly, a four-axis carton retrieval assembly, a flaring assembly, a sealing assembly, a lifting and rotating assembly, and a pushing and stacking assembly. The feeding assembly is located behind the storage assembly, and the stacking assembly is located behind the feeding assembly. During production, a forklift directly places a pallet with material onto the upper conveyor chain of the storage assembly. Once the lifting mechanism of the feeding assembly is level with the upper layer of the storage assembly, the pallet with material is conveyed onto the conveyor chain of the lifting mechanism. The lifting mechanism of the feeding assembly uses a camera and a laser distance sensor to move the top layer of the carton blank on the pallet to a designated height for retrieval. Each time a carton blank is retrieved, the lifting mechanism adjusts its height. When the camera on the feeding assembly detects that the carton blank has been consumed, the lifting mechanism descends to be level with the lower layer of the storage assembly, and the empty pallet is conveyed to the lower layer of the storage assembly by the conveyor chain. Then, it rises to the pallet receiving station to receive new pallets with material. Each time a forklift places a pallet with material on the upper layer of the storage assembly, it can remove the empty pallet from the lower layer of the storage assembly. The stacking assembly is equipped with a flaring assembly on top, a sealing assembly is located behind the flaring assembly, a lifting and rotating assembly is located at the bottom of the sealing assembly, and a stacking and pushing assembly is located behind the sealing assembly. The four-axis box picking assembly is mounted on the frame. The feeding assembly, stacking assembly, flaring assembly, lifting and rotating assembly, and sealing assembly are all installed inside the frame. The four-axis box picking assembly has sealing assemblies on the left and right sides of the box loading station.

[0005] Preferably, the storage assembly includes a first conveyor chain and a double-layer frame. The double-layer frame is equipped with a first conveyor chain, and the first conveyor chains on the double-layer frame convey in opposite directions. The upper layer of the double-layer frame is used to prevent material from being carried onto the pallet, and the lower layer of the double-layer frame is used to prevent empty pallets.

[0006] Preferably, the feeding assembly includes a lifting mechanism and a second conveyor chain, with the second conveyor chain mounted on the lifting mechanism.

[0007] Preferably, the stacking assembly includes a product conveyor belt, a stacking assembly, four corner rollers, and an accumulation channel. Four corner rollers are provided on the left and right sides of the stacking assembly, and an accumulation channel is provided at the bottom of the stacking assembly. The product conveyor belt is used to transport products onto the stacking assembly. When boxed products come out of the packaging machine, they will enter the product conveyor belt of the stacking assembly. The belt belt will send the products into the accumulation channel of the stacking mechanism. When the number of products accumulated in the stacking mechanism reaches the single-layer stack requirement, the four corner rollers on both sides of the stacking mechanism will rotate in opposite directions to push the single-layer products upward to form a product stack, and then receive new products to accumulate again.

[0008] Preferably, the four-axis box-picking assembly includes an X-axis module, a first Y-axis module, a second Y-axis module, a Z-axis module, sheet metal parts, an R-axis rotary table, a feeding station, and a packing station. The head and tail of the X-axis module are respectively provided with the first Y-axis module and the second Y-axis module. The first Y-axis module can move within the X-axis module, while the second Y-axis module cannot move within the X-axis module. The first Y-axis module and the second Y-axis module are respectively provided with the Z-axis module and the sheet metal parts. Both the Z-axis module and the sheet metal parts are provided with R-axis rotary tables. The feeding station is mounted on the Z-axis module via the R-axis rotary table, and the packing station is mounted on the sheet metal parts via the R-axis rotary table.

[0009] The four-axis carton picking assembly is used to pick up the top layer of carton blanks from the feeding station, open them to form open cartons, and then place them on the packing station. The assembly mainly consists of X, Y, and Z axis modules, an R-axis rotary platform, and an end-stage picking station. The X and Z axis modules are used to transfer the carton blanks from the feeding station to the packing station. Since the packing station is a fixed position (fixed coordinate point), but the carton blanks on the feeding station are not fixed in position due to stacking deviations, the Y-axis module and R-axis rotary table are used to assist in adjusting the position and angle of the end-stage picking station to ensure precise picking of the carton blanks. The coordinates of the top layer of carton blanks to be picked up on the feeding station are obtained through a camera and laser distance sensor, which guides the movement of the three-axis picking platform assembly.

[0010] Preferably, the flaring assembly includes a flaring frame, large ear baffles, side ear baffles, cylinders, gear racks, and baffle shafts. Baffle shafts are provided at the head, tail, left, and right sides of the flaring frame. Gear racks are connected to the tail of the baffle shafts. The large ear baffles and side ear baffles are connected to the flaring frame through the baffle shafts. When the open carton is placed in place, the cylinders of the two side ear baffles provide power to drive the rack to extend and retract. The rack drives the gear to rotate, and the gear drives the baffle shaft to rotate, thereby causing the side ear baffles installed on the baffle shaft to rotate and open, thus opening the two side ears of the open carton. After the two side ears of the open carton are opened, the upper and lower large ear baffles are also opened in the same way.

[0011] After the four baffles are opened, the four ears of the open carton are expanded to prevent the four ears from blocking the product stack during packing. They also serve as a guide for pushing the product stack into the carton. After packing is completed, the cylinder moves in the opposite direction, and the two large ear baffles retract first, and then the side ear baffles retract.

[0012] Preferably, the sealing assembly includes an upper large ear fixing and folding component, a glue spraying component, a side negative pressure shaping component, a side ear pressure plate, an upper large ear fixing suction cup, a first telescopic cylinder, a second telescopic cylinder, a hot melt glue gun, an upper large ear pressure plate, and a translation cylinder. The glue spraying component is located in the middle of the large ear folding component, the side negative pressure shaping component is located in front of the glue spraying component, the side ear pressure plate is located in front of the side negative pressure shaping component, the large ear pressure plate is installed on the head of the upper large ear fixing and folding component via the upper large ear fixing suction cup, the first telescopic cylinder is located on the right side of the head of the large ear fixing and folding component, the second telescopic cylinder is located at the bottom of the large ear fixing and folding component, the translation cylinder is located in the middle of the large ear fixing and folding component, and a hot melt glue gun is installed above the glue spraying component.

[0013] After the four-axis box picking assembly places the open carton at the packing station, the sealing assembly will be pushed towards the open carton by the first telescopic cylinder. The suction cups on the side negative pressure shaping assembly will hold the two sides of the open carton. At the same time, the upper ear fixing folding assembly will be pushed out to the upper ear by the second telescopic cylinder. The upper ear fixing suction cup will hold the upper ear to prevent it from collapsing and affecting the packing.

[0014] After the open carton is packed, the aforementioned flaring assembly retracts the large and side ear baffles. The hot melt glue gun on the glue spraying assembly, driven by the translation cylinder, sprays glue onto the four side ears. Then, the side ear pressure plate, driven by the cylinder, folds the four side ears inward. The upper large ear fixing suction cup breaks the vacuum, and the large ear pressure plate folds the large ear. After a short wait for the hot melt glue to adhere, the large ear pressure plate opens, the upper ear fixing folding assembly retracts, and the sealing assembly exits completely. At this point, the sealing process is complete. Wait for the sealed carton to be pushed out before the next sealing operation.

[0015] After securing the two sides and two large top lugs of the open carton, it awaits packing. The four-axis carton-retrieving fixture breaks the vacuum of all its negative pressure suction cups and pushes the carton out of the packing station, ready for the next pickup.

[0016] Preferably, the lifting and rotating assembly includes a non-powered roller, a lower large ear pressure plate assembly, a rotating cylinder, a first lifting cylinder and a second lifting cylinder. The lower large ear pressure plate assembly is provided with non-powered rollers on the top left and right sides, the lower large ear pressure plate assembly is provided with a rotating cylinder in the middle, the bottom of the rotating cylinder is connected to the first lifting cylinder, and the first lifting cylinder is provided on the left and right sides of the first lifting cylinder.

[0017] The lifting and rotating assembly is located below the sealing station and serves to support the carton during packing and sealing. It also lifts the carton and rotates it 90 degrees. After the open carton is packed and sealed, it needs to be sealed with tape. In order to allow the sealed carton to be directly sealed with tape by the conventional tape dispensers arranged on both sides of the conveyor channel during the downstream conveying process, the sealed carton needs to be rotated 90 degrees. First, the second lifting cylinder lifts the rotating cylinder and the sealed carton away from the bottom support surface. Then, the rotating cylinder rotates the sealed carton 90 degrees, the lifting cylinder retracts, and the sealed carton returns to the bottom support surface.

[0018] At this time, the bottom of the sealed carton rests on the unpowered roller and the lower large ear pressure plate assembly. To facilitate the ejection of the sealed carton, the first lifting cylinder retracts the lower large ear pressure plate assembly downwards, away from the sealed carton, so that the sealed carton rests only on the unpowered roller for easy ejection.

[0019] Preferably, the palletizing and box-pushing assembly includes a palletizing module, a product palletizing plate, a secondary cylinder, a carton pushing plate, a carton lifting cylinder, a box-pushing module, an automatic tape dispenser, and a conveyor belt. The product palletizing plate is installed on the palletizing module, and a secondary cylinder is provided on the product palletizing plate. The box-pushing module is located behind the palletizing module, and a carton lifting cylinder is provided on the carton pushing plate. A conveyor belt is located at the tail of the box-pushing module, and automatic tape dispensers are provided on both sides of the head of the conveyor belt.

[0020] After the stacking assembly completes stacking, the pusher module drives the product stack pusher plate to push the product stack from the flared assembly into the open carton. To save on the module's pushing and retracting cycle, a secondary pusher cylinder is also fixed on the product stack pusher plate. During the module's advancement process, the cylinder also performs a secondary push on the pusher plate, and the retracting process is similar.

[0021] After the sealing assembly completes its sealing and retracts, the pusher module moves the carton pusher plate to the sealing station in front of the sealed carton. During this movement, the carton pusher plate is lifted by the carton pusher plate lifting cylinder, allowing it to pass over the sealed carton. Once the sealed carton has been lifted and rotated 90 degrees, the carton pusher plate descends, and the pusher module drives the carton pusher plate to push the sealed carton backward. During this pushing process, the carton passes through the automatic tape dispenser, completing the sealing tape application.

[0022] Preferably, the storage assembly, feeding assembly, stacking assembly, four-axis box retrieval assembly, flaring assembly, sealing assembly, lifting and rotating assembly, and stacking and box pushing assembly are all equipped with cameras for monitoring.

[0023] The beneficial effects of this utility model are:

[0024] Space layout optimization: A linear layout is adopted, with all processes arranged in a straight line without branching structures. This controls the space occupied in one direction, making it easy to add the equipment to the original packaging machine layout, effectively saving workshop space and meeting the layout needs of different production workshops.

[0025] High degree of automation: The entire process from feeding, unpacking, stacking, packing to sealing is fully automated, reducing manpower input, lowering labor costs, and improving production efficiency.

[0026] Efficient and convenient material feeding: The automatic feeding assembly, through the cooperation of the storage and feeding components, realizes the automatic supply of carton blanks and the automatic recycling of empty pallets, eliminating the need for manual transfer of carton blanks and improving the efficiency and accuracy of material feeding.

[0027] Accurate and reliable packing and sealing: Various assemblies, such as stacking assemblies, flaring assemblies, and sealing components, work together to ensure that product stacks are accurately packed into cartons and sealed, thus guaranteeing the stability of packaging quality.

[0028] Convenient post-processing: The lifting and rotating assembly can rotate the sealed carton 90 degrees, allowing it to be directly sealed with tape using conventional tape dispensers on both sides of the conveyor channel during downstream transport, further improving the continuity and automation of the entire packaging process.

[0061] Working Principle: Feeding Process: The forklift places the pallet with material on the upper conveyor chain of the storage assembly. The lifting mechanism of the feeding assembly moves to be level with the upper layer of the storage assembly, and the pallet with material is conveyed to the conveyor chain of the lifting mechanism. The lifting mechanism uses a camera and laser distance sensor to send the top layer of cardboard boxes on the pallet with material to a designated height to await retrieval. Each time a cardboard box is removed, the lifting mechanism adjusts its height. When the cardboard boxes are used up, the lifting mechanism lowers to be level with the lower layer of the storage assembly, conveys the empty pallet to the lower layer of the storage assembly, and then rises again to receive pallets with material. At the same time, the forklift can remove the empty pallets from the lower layer.

[0062] Stacking process: After the boxed products come out of the packaging machine, they enter the product conveyor belt of the stacking assembly. The belt belt conveys the products into the accumulation channel of the stacking mechanism. When the accumulated product quantity reaches the single-layer stack requirement, the four corner rollers on both sides of the stacking mechanism rotate in opposite directions, pushing the single-layer products upward to form a product stack, and then receiving new products to accumulate again.

[0063] Box Picking and Flaring: The four-axis box picking assembly, via X, Y, and Z axis modules and an R-axis turntable, picks up the top layer of cardboard box blanks from the feeding station and transfers them to the packing station. Above the packing station, an opening cylinder and pressure plate open the cardboard box blanks to form open cartons. After the open cartons are placed in place, the side and large ear baffles of the flaring assembly open sequentially under the action of cylinders and gear racks, widening the side and large ears of the carton, providing guidance for product stacking and preventing the ears from obstructing the product stack.

[0064] Packing and sealing process: After the four-axis carton picking assembly places the open carton at the packing station, the sealing assembly is pushed forward by the telescopic cylinder. The suction cups of the side negative pressure shaping assembly hold the two sides of the carton, the upper ear fixing and folding assembly is pushed out, and the upper large ear fixing suction cup holds the upper large ear, ready for packing. After the stacking assembly completes the stacking, the stacking module drives the product stack pusher plate to push the product stack from the flaring assembly into the open carton. After packing is completed, the flaring assembly retracts the baffle, the hot melt glue gun of the glue spraying assembly sprays glue on the side ears, the side ear pressure plate folds the side ears, the large ear pressure plate folds the large ears, and after sealing, the sealing assembly is withdrawn as a whole.

[0065] Lifting, Rotating, and Pushing Stage: The lifting cylinder of the lifting and rotating assembly lifts the rotating cylinder and the sealing carton, and the rotating cylinder rotates the carton 90 degrees to facilitate subsequent sealing with tape. Afterwards, the lifting cylinder retracts, and the carton rests on the unpowered roller and the lower large ear pressure plate assembly. The lower large ear pressure plate assembly retracts, and the pushing module drives the carton pusher to push the carton backward. The automatic tape dispenser completes the sealing process, and finally, the carton is pushed out, completing the entire sealing process.

[0066] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
