Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bottle cap production, and particularly relates to a double-end gasket inserting machine. BACKGROUND

[0002] In the packaging industry, bottle caps are key components for sealing containers, and their airtightness is crucial for maintaining product freshness and safety. To achieve this goal, gaskets are widely used on various bottle caps to ensure that the bottle cap and the bottle nozzle fit tightly, and the gasket inserting machine is a device for inserting gaskets into the interior of the bottle cap. The core component of the gasket inserting machine is the plug-in mechanism, which is usually composed of a suction head and a suction head driving mechanism. The suction head uses negative pressure technology to adsorb the gasket, and then under the precise control of the suction head driving mechanism, the gasket is sent into the interior of the bottle cap until it contacts the inner bottom of the bottle cap, forming a bottle cap assembly. When the bottle cap is injection molded, the inner wall of the bottle cap is designed with a barb structure, which can prevent the gasket from falling out of the bottle cap and ensure the sealing effect.

[0003] However, in actual operation, since the diameter of the gasket is designed to be slightly larger than the inner diameter of the barb to ensure the blocking function, this design feature has become a major obstacle to the proper installation of the gasket. During the process of the gasket being pushed into the bottle cap by the suction head, the outer edge of the gasket is easily in close contact with the barb, and in some cases, the gasket may even be stuck by the barb, causing the gasket to not fall completely into the bottom of the bottle cap, resulting in incomplete assembly. Such an incompletely assembled bottle cap assembly is prone to falling out due to vibration or external force during subsequent logistics, storage or use, seriously damaging the sealing and safety of the product. More seriously, the existing gasket inserting machines generally lack real-time detection mechanisms for the quality of the bottle cap and gasket assembly. This means that even if the gasket is not properly installed, these defective bottle cap assemblies may successfully pass through the production line, enter the next process or be directly shipped, ultimately affecting the user experience of consumers and even causing product quality problems and damaging the brand image.

[0004] In view of the above problems, it is necessary to innovate the existing gasket inserting machine. INVENTION CONTENTS

[0047] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0048] The utility model provides a kind of double-end gasket plug-in machine, for how to improve the quality of the factory of bottle cap assembly 9 problem.

[0049] Referring to Figure 1 As shown in the figure, Figure 1 It is the perspective view of the double-end gasket plug-in machine in the embodiment, and the double-end gasket plug-in machine includes rack 1, conveying device 2, plug-in device 3, assembly detection device 4, good product discharging device 51 and defective product discharging device 52.

[0050] Assembly station 11, assembly detection station 12 and discharging station 13 are sequentially arranged on rack 1.

[0051] Conveying device 2 is installed on rack 1, and conveying device 2 is provided with limiting groove 21 for placing and limiting bottle cap 91. Conveying device 2 is used to convey bottle cap 91 in limiting groove 21 to assembly station 11, assembly detection station 12 and discharging station 13 in sequence.

[0052] Plug-in device 3 is installed on rack 1 and opposite to assembly station 11, and plug-in device 3 is used to press gasket 92 into bottle cap 91 on assembly station 11 to form bottle cap assembly 9.

[0053] The assembly detection device 4 is installed on the rack 1 and is opposite to the assembly detection station 12. The assembly detection device 4 is used to detect the depth of the gasket 92 in the bottle cap 91.

[0054] The good product discharging device 51 and the bad product discharging device 52 are both installed on the rack 1 and are opposite to the discharging station 13. The good product discharging device 51 is used to move the qualified bottle cap assembly 9 on the discharging station 13 out of the limiting groove 21. The bad product discharging device 52 is used to move the unqualified bottle cap assembly 9 on the discharging station 13 out of the limiting groove 21.

[0055] When the above technical solution is used, first, the conveying device 2 conveys the bottle cap 91 in the limiting groove 21 to the assembly station 11. Then, the plug pressing device 3 presses the gasket 92 into the bottle cap 91. After the bottle cap assembly 9 is formed, the conveying device 2 conveys the bottle cap assembly 9 to the assembly detection station 12. The assembly detection device 4 judges whether the gasket 92 in the bottle cap 91 is assembled in place. If the gasket 92 is assembled in place, the bottle cap assembly 9 is qualified. Otherwise, the bottle cap assembly 9 is unqualified. Finally, the conveying device 2 conveys the bottle cap assembly 9 to the discharging station 13. According to the detection result of the assembly detection device 4, if the bottle cap assembly 9 is qualified, the good product discharging device 51 moves the bottle cap assembly 9 out of the limiting groove 21. Otherwise, the bad product discharging device 52 moves the bottle cap assembly 9 out of the limiting groove 21. As can be seen, the double-head gasket plug-in machine can automatically assemble the bottle cap 91 and the gasket 92 through the plug pressing device 3. The assembly detection device 4 can detect the assembly of the bottle cap 91 and the gasket 92. In combination with the good product discharging device 51 and the bad product discharging device 52, the bottle cap assembly 9 can be classified and discharged according to the detection result of the assembly detection device 4, so as to avoid the unqualified bottle cap assembly 9 from flowing into the next process or flowing out of the factory, thereby effectively improving the quality of the bottle cap assembly 9 out of the factory.

[0056] The conveying device 2 can use an existing index plate, so that the assembly process, the assembly detection process and the discharging process of the bottle cap 91 and the gasket 92 can be continuously performed. The number of the limiting grooves 21 can be at least three. The limiting grooves 21 are annularly and spacedly distributed on the index plate. Three limiting grooves 21 are opposite to the assembly station 11, the assembly detection station 12 and the discharging station 13 respectively. In this way, the assembly process, the assembly detection process and the discharging process of the bottle cap 91 and the gasket 92 can be simultaneously performed without interference, so as to greatly improve the production efficiency.

[0057] The assembly detection device 4 can be formed by a depth sensing element 41 such as a displacement sensor and a lifting mechanism 42. As shown in Figure 3 Figure 3 ​As shown in the structural schematic diagram of the conveying device, the pressing device and the assembly detection device in the embodiment, when the assembly detection device 4 is in use, the lifting mechanism 42 drives the depth sensing member 41 to enter the bottle cap 91, so that the depth of the gasket 92 in the bottle cap 91 can be detected. The lifting mechanism 42 can use a linear displacement driving device such as an existing telescopic pneumatic cylinder or telescopic electric pole, and the output end thereof is screwed with the depth sensing member 41.

[0058] Referring to Figure 2 as shown in the figure, Figure 2 As shown in the structural schematic diagram of the conveying device, the pressing device and the assembly detection device in the embodiment, when the assembly detection device 4 is in use, the lifting mechanism 42 drives the depth sensing member 41 to enter the bottle cap 91, so that the depth of the gasket 92 in the bottle cap 91 can be detected. The lifting mechanism 42 can use a linear displacement driving device such as an existing telescopic pneumatic cylinder or telescopic electric pole, and the output end thereof is screwed with the depth sensing member 41.

[0059] The above-mentioned position detection mechanism can use an optical sensor or an infrared sensor.

[0060] Alternatively, two position detection workstations 14 can be arranged on the rack 1, and the position detection device 6 is correspondingly provided with two position detection workstations 14, one position detection workstation 14 is located upstream of the assembly workstation 11, and the other position detection workstation 14 is located downstream of the discharging workstation 13, as Figure 3 shown in the figure, the position detection device 6 of the position detection workstation 14 is also used for detecting whether the bottle cap 91 is placed in the limiting groove 21, so that the good product discharging device 51 or the defective product discharging device 52 can be prevented from being out of order, and the situation that the bottle cap assembly 9 is not discharged and moved out of the conveying device 2 can be avoided.

[0061] Referring to Figure 2 and Figure 3As shown in an embodiment of the gasket inserting device 3, the gasket inserting device 3 comprises a suction cup 31 and a suction cup driving mechanism 32. The gasket stock 15 for stacking the gaskets 92 is installed on the frame 1. The suction cup 31 is located below the gasket stock 15 for sucking or releasing the gaskets 92. The suction cup driving mechanism 32 is installed on the frame 1 and is in driving connection with the suction cup 31. The suction cup driving mechanism 32 is used to drive the suction cup 31 to reciprocate between the gasket stock 15 and the conveying device 2. In this way, the double-end gasket inserting machine can drive the suction cup 31 to be in butt joint with the gasket stock 15 by the suction cup driving mechanism 32, so that the suction cup 31 can suck the gaskets 92 in the gasket stock 15, and can also drive the suction cup 31 to move into the limiting groove 21 of the conveying device 2 to insert the gaskets 92 into the bottle cap 91, thereby completing the assembly of the bottle cap 91 and the gasket 92.

[0062] The suction cup 31 can be connected with the existing vacuum suction device by using the existing suction accessory, and can suck the gaskets 92 out of the gasket stock 15 by the negative pressure suction.

[0063] Referring to Figure 3 As shown in an embodiment of the suction cup 31, the number of the suction cups 31 is at least two, each of the suction cups 31 is connected to the output end of the same suction cup driving mechanism 32, and the number of the gasket stock 15 and the suction cup 31 is the same and corresponds one by one. In this way, the gasket inserting device 3 can simultaneously assemble at least two bottle caps 91 and gaskets 92 by two suction cups 31, thereby effectively improving the efficiency of assembling the bottle caps 91 and the gaskets 92 in large quantities.

[0064] Referring to Figure 3As shown, in one embodiment of the suction cup driving mechanism 32, the suction cup driving mechanism 32 comprises a lifting driving member 321, a lifting frame 322 and a rotating shaft 323. The lifting driving member 321 is arranged on the rack 1 by welding or screwing, etc., and is in transmission connection with the lifting frame 322. The rotating shaft 323 is rotationally connected to the lifting frame 322, and each suction cup 31 is distributed on the rotating shaft 323 in axial direction. Among them, the rack 1 is provided with a rack 16 by welding or screwing, etc., and the rotating shaft 323 comprises a gear 3231 for engaging with the rack 16. The lifting driving member 321 is used to drive the lifting frame 322 to move up and down, so as to drive the rotating shaft 323 to overturn and move up and down. The stroke of the rotating shaft 323 in the upward or downward direction is greater than the length of the rack 16. In this way, the process of inserting the double-headed gasket into the bottle cap 91 and the gasket 92 is as follows: the suction cup 31 is in butt joint with the gasket cylinder 15 at the original position, the suction cup 31 first adsorbs the gasket 92 in the gasket cylinder 15, then the lifting driving member 321 drives the lifting frame 322 to move downward, the lifting frame 322 drives the rotating shaft 323 to overturn and move downward at the same time, so as to make the suction cup 31 overturn to face the limiting groove 21 of the conveying device 2, then the lifting driving member 321 continues to drive the lifting frame 322 to move downward, so that the gear 3231 is disengaged downward from the rack 16, the overturning of the suction cup 31 is stopped, the suction cup 31 is kept facing the conveying device 2, and the suction cup 31 and the gasket 92 are vertically pressed into the bottle cap 91, the assembly of the bottle cap 91 and the gasket 92 is completed, after the assembly, the suction cup 31 releases the gasket 92, at the same time, the lifting driving member 321 drives the lifting frame 322 to move upward, the suction cup 31 is vertically moved out of the bottle cap 91, and the gear 3231 is re-engaged upward with the rack 16, then the lifting driving member 321 continues to drive the lifting frame 322 to move upward, so as to make the suction cup 31 move upward and overturn to face the gasket cylinder 15, and return to the original position. It can be seen that the suction cup driving mechanism 32 can drive the overturning and lifting movement of a plurality of suction cups 31 by one driving source of the lifting driving member 321, so as to realize the assembly of at least two bottle caps 91 and gaskets 92, and greatly save the driving cost.

[0065] The above lifting driving member 321 can use an existing telescopic air cylinder or telescopic electric rod, etc., linear displacement driving device, which is arranged on the rack 1 by welding or screwing, etc., and the output end of the lifting driving member 321 is connected with the lifting frame 322 by welding or screwing, etc.

[0066] Referring to Figure 1 , Figure 2 and Figure 3As shown in any of the above embodiments, the double-end gasket inserting machine further comprises a positioning device 7. The positioning device 7 is installed on the frame 1 and is opposite to the assembling station 11, and is used to abut against the bottle cap 91 on the assembling station 11 to fix the bottle cap 91 in the limiting groove 21. In this way, the positioning device 7 can effectively avoid the displacement of the bottle cap 91 during the assembling process with the gasket 92, so as to affect the assembling quality of the bottle cap 91 and the gasket 92.

[0067] Referring to Figure 2 and Figure 3 As shown in an embodiment of the positioning device 7, the positioning device 7 comprises an abutting plate 71 and an abutting plate driving member 72. The abutting plate driving member 72 is installed on the frame 1 by welding or screwing, etc., and the output end of the abutting plate driving member 72 is connected with the abutting plate 71 by welding or screwing, etc. The abutting plate driving member 72 is used to drive the abutting plate 71 to displace towards or away from the slot opening 211 of the limiting groove 21. In this way, when the abutting plate driving member 72 drives the abutting plate 71 to displace towards the slot opening 211 of the limiting groove 21, the abutting plate 71 can tightly abut against the bottle cap 91 in the limiting groove 21 to fix the bottle cap 91 in the limiting groove 21. When the abutting plate driving member 72 drives the abutting plate 71 to displace away from the slot opening 211 of the limiting groove 21, the assembled bottle cap 91 can be released, so as to facilitate the conveying device 2 to convey it to the next station.

[0068] The above abutting plate driving member 72 can use existing linear displacement driving devices such as telescopic air cylinders or telescopic electric poles.

[0069] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in any of the above embodiments, the double-end gasket inserting machine further comprises a positioning device 7. The positioning device 7 is installed on the frame 1 and is opposite to the assembling station 11, and is used to abut against the bottle cap 91 on the assembling station 11 to fix the bottle cap 91 in the limiting groove 21. In this way, the positioning device 7 can effectively avoid the displacement of the bottle cap 91 during the assembling process with the gasket 92, so as to affect the assembling quality of the bottle cap 91 and the gasket 92. Figure 4For the structural schematic diagram of the conveying device, the hopper, the lifting conveying chain and the gravity slide rail in the embodiment, on the basis of the above-mentioned in-place detection station 14, the rack 1 is further provided with a feeding station 17, and the feeding station 17 is located upstream of the in-place detection station 14. The double-end gasket plug-in machine further comprises a hopper 81, a lifting conveying chain 82 and a gravity slide rail 83. The lifting conveying chain 82 is arranged obliquely upward. The hopper 81 is installed at the lower end of the lifting conveying chain 82. The gravity slide rail 83 is arranged obliquely downward, and the upper end of the gravity slide rail 83 is connected with the upper end of the lifting conveying chain 82, and the lower end of the gravity slide rail 83 is connected with the conveying device 2 at the feeding station 17. Among them, the hopper 81 is used to convey the bottle cap 91 to the lifting conveying chain 82, the lifting conveying chain 82 is used to convey the bottle cap 91 to the gravity slide rail 83, and the gravity slide rail 83 is used to convey the bottle cap 91 to the conveying device 2. In this way, when feeding the bottle cap 91, first, the worker pours a large amount of bottle cap 91 into the hopper 81; then, the hopper 81 conveys the bottle cap 91 to the lifting conveying chain 82, and the lifting conveying chain 82 conveys the bottle cap 91 to the gravity slide rail 83; finally, the bottle cap 91 slides downward along the gravity slide rail 83 under the action of its own gravity and enters the conveying device 2. It can be seen that when the double-end gasket plug-in machine feeds the bottle cap 91, the worker can directly pour the bottle cap 91 into the hopper 81 at the low place, and the lifting conveying chain 82 lifts the bottle cap 91 to the gravity slide rail 83, without manual lifting, greatly saving manpower and improving production efficiency. The bottle cap 91 in the gravity slide rail 83 can automatically slide downward by its own gravity, and smoothly enters the limiting groove 21 of the conveying device 2 by the large inertia generated by the downward sliding, without the need for an additional pushing mechanism, saving driving cost.

[0070] The above-mentioned lifting conveying chain 82 can use an existing chain transmission type lifting conveyor.

[0071] Referring to Figure 4 In an embodiment of the lifting conveying chain 82, a guide rod 821 is arranged on the lifting conveying chain 82 by screwing or welding, and the guide rod 821 is parallel to the conveying surface of the lifting conveying chain 82. The guide rod 821 is obliquely directed towards the gravity slide rail 83, and the lifting conveying chain 82 is used to guide the bottle cap 91 on the conveying chain to enter the gravity slide rail 83. In this way, when feeding the bottle cap 91, the bottle cap 91 on the conveying surface moves upward along with the lifting conveying chain 82, and when the bottle cap 91 abuts against the guide rod 821, the bottle cap 91 cannot continue to move upward along with the lifting conveying chain 82, and moves along the guide rod 821 obliquely towards the gravity slide rail 83 under the action of the upward force of the lifting conveying chain 82, thereby realizing the conveying of the bottle cap 91 from the lifting conveying chain 82 to the gravity slide rail 83.

[0072] Referring to Figure 1As shown, in one embodiment of the gravity slide rail 83, a speed-regulating ratchet 831 is installed on the gravity slide rail 83. The speed-regulating ratchet 831 is partially located inside the gravity slide rail 83, preventing bottle caps 91 from continuously entering the gravity slide rail 83 and avoiding blockage within the gravity slide rail 83, thus preventing the bottle caps 91 from generating sufficient inertial force to enter the conveying device 2. Furthermore, the speed-regulating ratchet 831 can be driven to rotate by an external rotating mechanism. When the speed-regulating ratchet 831 rotates, it can drive the bottle caps 91 at the upper end of the gravity slide rail 83 through the speed-regulating ratchet 831, and then slide them downwards into the conveying device 2. It can be seen that the speed-regulating ratchet 831 can adjust the flow rate of the bottle caps 91 entering the conveying device 2 within the gravity slide rail 83, ensuring that after the conveying device 2 transports the empty limiting groove 21 to the loading station 17, the bottle caps 91 in the gravity slide rail 83 then enter the limiting groove 21 of the conveying device 2, preventing the bottle caps 91 from being blocked while sliding downwards.

[0073] See Figure 1 and Figure 5 As shown, Figure 5For the structural schematic diagram of the conveying device, the assembly detection device, the good product discharging device and the defective product discharging device in the embodiment, in one embodiment of the good product discharging device 51 and the defective product discharging device 52, the discharging station 13 includes a good product discharging station 131 and a defective product discharging station 131, the good product discharging device 51 and the defective product discharging device 52 are respectively opposite to the good product discharging station 131 and the defective product discharging station 131, and the good product discharging device 51 and the defective product discharging device 52 each include a blocking plate 521, a blocking plate driving member 522, a blowing pipe 523 and a discharging guide plate 524. The blocking plate driving member 522 is arranged on the rack 1 by screwing or welding and the like, and is in transmission connection with the blocking plate 521. The blocking plate driving member 522 is used to drive the blocking plate 521 to move towards or away from the slot opening 211 of the limiting groove 21, so as to block or open the slot opening 211 of the limiting groove 21.
