Description

Technical Field

[0001] The invention belongs to the field of post-filling capping, and in particular relates to an automatic filling and capping device. Background Art

[0002] In the product packaging process of many industries, the capping process is one of the key steps, which is mainly divided into two types: manual and automatic. Manual capping relies on manual rotation of the lid to close the container. This method is more common in small-scale production scenarios. However, its disadvantages are also very significant. In the field of pharmaceutical product filling, excessive manual intervention not only increases the labor cost investment, but also greatly increases the risk of secondary pollution, posing a serious threat to product quality and safety. For manual filling and capping operations of food-grade products, it is difficult to accurately control the force and angle, and liquid overflow is prone to occur during the packaging process, resulting in waste of raw materials and affecting the appearance of the packaging. In addition, excessive force or improper operation during manual filling may also cause carbonization of blackheads in the filled liquid, which directly affects product quality.

[0003] With the continuous expansion of production scale, automatic capping technology has emerged and is suitable for large-scale production. Despite this, current similar filling and capping machines still have many shortcomings and cannot meet the growing production needs and strict quality standards. Especially when faced with the situation of caps with inner plugs and the diversification of bottle materials and styles, the compatibility and adaptability of existing equipment are poor. For example, when filling special liquids such as flammable media, sterile media and edible liquids, since these liquids have extremely high requirements for the filling environment and packaging sealing, current equipment cannot provide a complete set of automated solutions that integrate filling, capping and testing, which seriously restricts the efficient and safe production of related industries.

[0016] Beneficial effects of the present invention:

[0017] 1. Aiming at the problem that bottles are prone to fall over when feeding the bottle unscrambler, the present invention innovatively adopts a conveying method that combines bottom belt conveyor and single-side belt conveyor. In the process of bottles transitioning from the bottle unscrambler to the filling and capping machine, the single-side belt conveyor plays a key role, which cleverly transforms the transition mode of bottles from traditional fixed linear transmission to linear spiral rotation transmission. This unique conveying method allows the bottles to rotate while moving forward, effectively avoiding the problem of bottles falling over online, greatly improving the stability and efficiency of bottle conveying, and ensuring the continuity of the entire filling and capping production process;

[0018] 2. Considering that the lid packaging material factory cannot guarantee that the lid plug is 100% intact, and the vibration feeding and other factors during the production process may cause the lid plug to separate, this equipment is equipped with an advanced lid plug detection mechanism. This mechanism uses the mold cavity inner hole shape positioning technology, combined with screw cylinder, floating rod and other components, to accurately detect the presence of the lid plug. According to the height difference caused by the presence or absence of the lid plug, the height of the lid flat surface is accurately determined by a high-precision optical fiber sensor. Once it is detected that the lid has no plug, the screw cylinder rises rapidly, and the material picking module (PPU manipulator) will promptly clamp and move the unqualified lid to the defective product storage box and kick it out. At the same time, the signal is fed back to the material picking module, so that it can re-pick the material from the picking position for detection. This independently controlled detection and rejection mechanism effectively ensures the integrity and quality reliability of product packaging, and avoids product leakage or other quality problems caused by the lack of lid plugs.

[0019] 3. This equipment has made significant breakthroughs in capping technology. A unique capping principle is designed according to the appearance characteristics and material properties of different caps. The capping head uses silicone block as the contact block material, which is interlocked with the appearance of the cap through interference fit, and axially rotates with the help of the friction of the silicone block, so that the cap can achieve self-locking function and ensure a good sealing effect. At the same time, the capping head has practical functions such as quick release and quick change self-locking, which is convenient for rapid replacement and adjustment according to different production needs. During the capping process, the capping assembly adopts a floating method. The capping servo motor accurately controls the torque and feedback force to make the capping device, screwdriver, screwdriver connecting shaft, sleeve, floating shaft spring and other components work together to achieve axial rotation. The Z-axis lifting servo motor controls the descent of the capping assembly, and the floating spring is consistent with the rotating axis when the cap is screwed, and it rotates while pressing down to always maintain the consistency of friction. By carefully setting the torque parameters of the servo motor, accurate and stable capping operations can be achieved according to the requirements of different caps and bottles, ensuring that each bottle cap can achieve the ideal locking and sealing effect, effectively improving the packaging quality and shelf life of the product, and reducing quality risks such as product leakage.

[0020] 4. This automatic filling and capping equipment realizes a high degree of integration of multiple stations, integrating a series of complex processes such as automatic feeding, precise detection, efficient filling, detection of defective products in the cap to kick out, precise capping, automatic capping and smooth unloading. This highly integrated design greatly reduces manual intervention, effectively reduces labor costs, and greatly improves production efficiency. The connection between each station is tight and smooth. Through the turntable bottle feeding method and advanced control system, the orderly and rapid transfer of bottles between different stations is realized, ensuring the automation and continuity of the entire production process. Whether it is the filling of different high-viscosity fluids in various industries such as pharmaceutical products, daily chemical products, or oils and fats, this equipment can provide stable, efficient and high-quality solutions, significantly improving the production efficiency and market competitiveness of the enterprise, and promoting the automated production process of related industries.

[0064] Embodiment 2:

[0065] Workflow

[0066] S1: Bottle feeding

[0067] The bottles are arranged and discharged by the bottle unscrambler, and its material channel adopts a non-powered transmission method, relying on the mutual push between the bottles to make the bottles move forward and prepare to enter the bottle conveying mechanism 2.

[0068] S2: Bottle conveying and bottle tipping prevention (bottle feeding stage)

[0069] The bottle enters the bottle inlet anti-falling assembly 22 of the bottle conveying mechanism 2 from the bottle unscrambler. The speed regulating motor 221 of the side-standing belt conveyor in the bottle inlet anti-falling assembly 22 is started, driving the first driving shaft 226 to rotate, and the first driving shaft 226 in turn drives the first driven shaft 227 connected thereto to rotate, so that the first side-standing belt 224 installed on the first driven shaft 227 rotates clockwise. At this time, the first side-standing belt 224 is consistent with the belt rotation direction of the conveyor line 211. The first side-standing belt 224 generates tangential friction with the bottle body, so that the bottle is transformed from the original fixed state to a linear spiral rotation conveyor. In this process, the bottle rotates and moves forward at the same time, which effectively prevents the bottle from tipping over when it transitions from the bottle unscrambler to the bottle separation flange 3. At the same time, the bottle inlet photoelectric sensor 223 installed on the first guide fixed plate 225 will detect whether the bottle enters the area, and the material inspection photoelectric sensor 228 will detect whether the bottle has material. The inlet side belt speed regulator 229 can adjust the speed of the inlet side belt conveying speed regulating motor 221, and then control the conveying speed of the first side belt 224 to meet different production requirements.

[0070] The bottles processed by the bottle-inverting prevention assembly 22 smoothly enter the conveyor line 211. The conveyor line 211 is powered by a conveyor line speed regulating motor 213, and its speed can be adjusted by a conveyor line speed regulator 212. The bottles are smoothly transported on the conveyor line 211 and move toward the bottle separation flange 3.

[0071] S3: Bottle separation operation

[0072] When the bottle reaches the bottle separation flange 3, the bottle feeding and bottle separation servo motor 31 drives the bottle separator 33 to start working. The bottle separator 33 rotates in an open gear shape, and accurately delivers the bottle from the inlet side of the conveyor line 211 through the opening of the guide fence 34 and the third guide fixed plate 37 to the material opening of the turntable 35. In this process, the PLC control system will accurately control the speed matching of the bottle separator 33 and the turntable 35 to ensure that the rotation speeds of the two are synchronized, so that the bottle can smoothly enter the turntable 35.

[0073] S4: Bottle front and back inspection

[0074] The turntable 35 is driven by the turntable servo motor 32 to rotate at an equal angle and transport the bottle to the position of the bottle front and back detection mechanism 9. At this time, the lifting cylinder of the bottle front and back detection mechanism 9 descends, driving the bottle lifter at the front end of the floating shaft to move. If the bottle is facing up, the bottle lifter at the front end of the floating shaft will be inserted into the bottle mouth, and the floating height will drop by 10mm; on the contrary, if the bottle is facing up, the bottle lifter at the front end of the floating shaft will contact the bottom of the bottle, the floating shaft will be compressed upward by 10mm, and the shaft end face will trigger the proximity switch. The PLC control system uses the signal of the proximity switch as the judgment condition. If it is detected that the bottle is facing up, the equipment will suspend operation and wait for manual processing to ensure the accuracy of subsequent filling and capping operations.

[0075] S5: Filling process

[0076] After the bottles have passed the inspection on both sides, they are transported to the position of the filling mechanism 4 as the turntable 35 continues to rotate. The lifting cylinder of the filling mechanism 4 descends, so that the filling needle is accurately inserted into the bottle mouth. Then, the pump starts to press the liquid into the bottle with high precision (accuracy reaches 5‰). When the filling is completed, the pump will send a signal to the PLC control system, and the PLC control system will control the lifting cylinder to rise, complete the filling action, and prepare to enter the next process.

[0077] S6: Cap supply and plug detection

[0078] The lids are fed through the vibrating feeding tray 5, which has a double feeding channel, and can efficiently provide lids for subsequent processes. The PPU manipulator mechanism 6 starts to work, and its servo motor 61 drives the PPU 62 to move to the front end of the double feeding channel of the vibrating feeding tray 5. With the auxiliary positioning of the slot-type photoelectric sensor 63 and the first linear slide rail 66 to ensure the smooth movement, the clamping cylinder 68 at the bottom of the connecting plate 67 accurately takes the lid out of the vibrating feeding tray and places it on the lid plug detection mechanism 7.

[0079] The material detection photoelectric sensor 77 in the cover plug detection mechanism 7 first detects whether the cover is in place. Then, the screw cylinder 78 on the screw cylinder mounting plate 73 is started, and its cylinder shaft pushes the push rod 79 up (the first spring 74 on the outside of the push rod 79 plays a buffering role), and the cover is inserted into the mold cavity 75 on the push rod 79, and the positioning is achieved through the shape of the inner hole of the mold cavity. Since there is a height difference between the cover with an inner plug and the cover without an inner plug (for example, the height difference is 8mm), when the cover has an inner plug, the push rod 79 supports the inner wall of the inner plug, and the optical fiber sensor 76 cannot read and identify the bottom surface of the cover opening, and it is judged as a qualified product; if the cover has no inner plug, the push rod 79 supports the inner cap end of the cover, and the cover will sink into the mold cavity of the mold 75, and the bottom surface of the cover opening triggers the optical fiber sensor 76, which is judged as a defective product. The PPU manipulator mechanism 6 will clamp the defective cover and put it into the defective product storage box, and re-take the cover from the material taking position for inspection to ensure that the upper cover is a qualified product.

[0080] S7: Cover operation

[0081] The qualified caps after the cap plug detection are taken out from the cap plug detection mechanism 7 by another clamping action of the PPU robot mechanism 6 (which can be understood as different action stages of the same mechanism). The clamping cylinder clamps the cap and moves it to the capping position, accurately putting the cap on the bottle mouth and putting it on the bottle, completing the capping operation, and the bottle is ready to enter the capping process.

[0082] S8: Check if the lid is on

[0083] The bottle with the cap is transported to the position of the cap detection mechanism 10 as the turntable 35 rotates. The photoelectric sensor of the cap detection mechanism 10 identifies the cap on the bottle. If it is detected that the bottle has no cap, the equipment will suspend operation and wait for manual processing. After the cap is added, the start button is pressed and the equipment continues to operate normally to ensure the smooth progress of the subsequent capping process.

[0084] S9: Capping process

[0085] The bottles that have passed the cap detection are transported by the turntable 35 to the position where the cap screwing mechanism 8 can be easily disassembled and tightened. First, the bottle positioning cylinder 82 extends to fix the bottle body at the material opening of the turntable 35 by positioning the bottle body in shape. Then, the Z-axis lifting servo motor 86 reverses, driving the ball screw 83 to move linearly downward with the assistance of the second linear slide 84, thereby lowering the cap screwing structure 85 installed on the ball screw 83 and the second linear slide 84.

[0086] The capping structure 85 starts to work, the capping servo motor 8501 rotates forward, and the motor shaft drives the floating shaft 8504 to rotate through the coupling 8502, thereby causing the screwdriver bit 8508, the screwdriver bit connecting shaft 8507, the sleeve 8506 and other components installed at the bottom of the floating shaft 8504 to rotate axially. The silicone 8510 is installed at the bottom of the screwdriver bit 8508 through the capping machine, and forms an interference fit with the shape of the cap. During the capping process, the torque and feedback force are accurately controlled by the capping servo motor 8501. At the same time, the Z-axis lifting servo motor 85 moves downward, and the capping assembly adopts a floating mode (the second spring 8505 ensures the floating effect), rotating and pressing down to maintain the consistency of friction, thereby achieving a good locking and sealing effect. Multiple convenient disassembly and tightening bottle cap mechanisms 8 can perform capping operations on multiple bottles at the same time, thereby improving production efficiency.

[0087] S10: Bottle output

[0088] After the capping is completed, the bottle is transported to the discharge position as the turntable 35 rotates. The bottle is guided out through the guide plate and flows into the conveyor line 211. At this time, the bottle outlet anti-falling assembly 23 of the bottle conveying mechanism 2 starts to work, and the side belt conveying speed regulating motor 231 drives the second side belt 233 to rotate clockwise (the same principle as the bottle inlet anti-falling assembly). The bottle rotates and moves forward again under the action of the side belt to prevent tipping, and is finally sent to the labeling machine line docked at the rear end to enter the next production process. In the entire workflow, the common module provides a stable installation foundation for each mechanism, ensuring that the mechanisms can work accurately together, and realizing efficient, accurate and stable operation of automatic filling and capping.

Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention should be defined by the claims.
