Description

Technical Field

[0001] The present invention relates to the technical field of motorcycle packaging, in particular to an automatic packaging production line. Background Art

[0002] In the field of automated motorcycle packaging production, traditional lifting systems generally use monorail pneumatic hoists for vertical lifting operations. Operators need to repeatedly adjust the position of the hoist to adapt to different models. The lack of intelligent planning of the lifting trajectory results in the equipment idle period being much longer than the effective operating time. The AC and DC lines in the pit are mixed and not shielded. The metal frame and the humid environment cause electrolytic corrosion, which accelerates the aging and cracking of the cable insulation layer. What is more serious is that the metal debris generated during the operation of the equipment is easily accumulated in the gaps of the transmission mechanism, and long-term friction generates heat to form high-temperature points, posing a potential source of combustion risk.

[0003] Structural imbalance in the conveying system is a common problem in the baling line area. There is a design fault in the mechanical interface between the powered plate chain and the unpowered roller. The packaging boxes are randomly deflected due to the lack of a guide mechanism when transported across areas. The boxes and the edges of the conveyor line frequently rub against each other, causing surface damage. The line power supply system uses an open relay control architecture. The surge current generated when high-power equipment in the workshop starts and stops can easily cause control signal disorder, resulting in sudden stops of the conveyor line or speed loss. Such systemic defects make it difficult for the qualified rate of the baling process to exceed the industry benchmark, seriously restricting the refined packaging requirements of high-end models.

[0004] The technological shortcomings in the storage and transportation links are mainly reflected in the contradiction between passive transportation and discrete operations. The packaged finished products rely on the physical thrust of the subsequent boxes to achieve displacement. The collision and extrusion between boxes cause the cracking rate of the sealing tape to increase significantly. Forklift transfer still uses the single picking mode of manual visual positioning. The operation path repetition rate is extremely high and multi-unit merging operation cannot be achieved. The labeling process of paper packaging boxes uses contact inkjet technology. The ink is easily affected by environmental humidity and causes smudging before solidification. The recognizability of batch product traceability codes is uneven. The existing storage and transportation area roller lines lack dynamic caching strategies. Energy consumption is prominent during full load stagnation, and the equipment energy efficiency ratio has been in the non-economic range for a long time. Summary of the Invention

The flat design effectively eliminates the risk of loading and unloading drop; the plate chain conveyor belt 31 of the strapping plate chain assembly line 3 has a built-in multi-point pressure sensing device, which monitors the tightness of the box in real time during the wooden box assembly process and feeds back to the PLC system to automatically adjust the clamping force; the photoelectric positioning sensor 62 equipped on the straightening chain plate line 6 can dynamically capture the edge coordinates of the wooden box, and link the lateral cylinder push rod 61 to perform millimeter-level displacement correction to ensure that the strapping path of the subsequent baler 71 is accurately overlapped; the segmented drive structure of the automatic strapping chain conveyor line 7 Speed matching is achieved through the synchronous control unit 74 of the front drive module 72 and the rear drive module 73, and the climbing structure adapts to the conveying inclination angle of wooden boxes of different sizes, so that the side-type fully automatic baler 71 can still complete three high-strength strapping under high-speed operation; the 90-degree translation offline mechanism 4 integrates the anti-slip climbing transition section 43 and the bidirectional power roller 42, and realizes impact-free steering transportation under the drive of the lifting cylinder 41, effectively avoiding scratches on the surface of the box; the accumulation and release storage and transportation system 5 achieves continuous accumulation and storage while completing the unique identification printing through the deep integration of the laser marking machine 51 and the cache roller line 52, and forms a flexible buffer zone for forklifts to pick up goods in batches with the segmented start and stop logic of the power roller body 521 and the unpowered roller body 522; the entire line is controlled by a PLC system to achieve full-process data interoperability and intelligent scheduling, and the fault emergency unit diagnoses equipment abnormalities in real time and triggers protective shutdowns.

[0034] Please see the attached Figure 1 -Attached Figure 10The 90-degree translation offline mechanism 4 includes a lifting cylinder 41, a bidirectional power roller 42 and a climbing transition section 43 with anti-slip grooves. The bidirectional power roller 42 is arranged inside the climbing transition section 43, and the lifting cylinder 41 is arranged inside the climbing transition section 43. The laser marking machine 51 of the accumulation storage and transportation system 5 is connected to the outside of the cache roller line 52. The cache roller line 52 is divided into sections with a power roller body 521 and a non-powered roller body 522. The correction chain plate line 6 realizes secondary positioning through the lateral cylinder push rod 61 and the photoelectric positioning sensor 62.

The PLC joint control system includes a control unit, a fault emergency unit and a production data traceability module. The size range of packaging boxes suitable for the production line covers vehicle transport carriers with wooden frames and steel frames.

[0035] Specifically, through the coordinated action of the lifting cylinder 41 and the bidirectional power roller 42 of the 90-degree translation offline mechanism 4, impact-free steering and transportation of wooden boxes is achieved in the climbing transition section 43 with anti-skid grooves. Its dual-power drive mode ensures that large-mass packaging boxes maintain a uniform motion trajectory when turning; the laser marking machine 51 of the accumulation and release storage and transportation system 5 adopts dynamic following technology to mark the packaging boxes that are continuously moving on the cache roller line 52 in real time.

[0036] Working principle: The operator hangs and lifts the motorcycle to the position where the rear wheel is off the ground through the chain electric hoist 12 of the lifting system 1, and then the electric sports car 13 automatically moves along the KBK track 11 to the top of the bottom support chain conveyor line 2. The independent electronic control module 14 controls the precise positioning and completes the docking and fixation of the vehicle and the wooden bottom support. The power chain segment 21 of the bottom support chain conveyor line 2 carries the wooden bottom support for stable transportation through three rows of drive chains. The unpowered roller segments 22 on both sides are assisted by free-rolling rollers to correct the position to prevent deviation. The plate chain conveyor belt 31 of the baling plate chain assembly line 3 sends the wooden bottom support to the wooden box assembly station to complete the box fixation. The correction chain plate line 6 detects the position of the wooden box through the photoelectric positioning sensor 62, triggers the lateral cylinder push rod 61 to push the box to the side of the plate chain to achieve precise side positioning. The segmented chain drive structure of the automatic packaging chain conveyor line 7 is driven by the front section Module 72 and the rear drive module 73 synchronously transport the wooden boxes to the two side-type fully automatic balers 71 workstations. After completing three parallel strappings, the synchronous control unit 74 maintains the consistency of the conveying rhythm. The lifting cylinder 41 of the 90-degree translation offline mechanism 4 descends to make the strapped wooden boxes fall to the bidirectional power roller 42, and a 90-degree turn is achieved through the climbing transition section 43 with anti-slip grooves. The laser marking machine 51 of the accumulation storage and transportation system 5 extends the machine head to complete the label printing after the wooden boxes are in place. The power roller body 521 of the cache roller line 52 cooperates with the unpowered roller body 522 to transport the finished products to the accumulation section for temporary storage. The PLC joint control system coordinates the start and stop of each section of equipment in real time. When it is detected that the accumulation section is full, the line will automatically stop and wait for the forklift to pick up the goods. The entire line quickly responds to abnormal working conditions through the fault emergency unit. The production data traceability module records the operating parameters of each link to achieve quality tracking.
