Description

Technical Field

[0001] The present invention relates to the technical field of nail gun cartridge production, and particularly relates to an alignment and transfer device and method specifically for nail gun cartridges. Background Art

[0002] In the production and manufacturing process of nail gun cartridges, the alignment and transfer of nail gun cartridges is a crucial link. However, there are many difficulties and disadvantages in this link at present, which seriously affect production efficiency and product quality.

[0003] First of all, the shape of the nail gun cartridge is special, and its structure is not a regular geometric body, which makes it difficult to achieve precise positioning during alignment and transfer. When traditional transfer devices and positioning devices deal with this special shape, the cartridges often have various postures, and it is impossible to ensure that all cartridges enter the subsequent processing procedures in a unified and correct posture. This not only makes it difficult to accurately operate the subsequent procedures, but may also cause equipment failures due to the deviation of the cartridge position. For example, when filling gunpowder or assembling the primer, cartridges with inaccurate positions will cause inconsistent filling amounts or insecure assemblies.

[0004] Secondly, the existing alignment and transfer methods are inefficient. Some production lines use manual assistance for alignment and transfer. This method not only consumes a large amount of manpower, but also the manual operation speed is limited, making it difficult to meet the requirements of large-scale and high-efficiency production. And some automated transfer systems, due to insufficient adaptability to nail gun cartridges, frequently experience jams and blockages during transfer, and need to be continuously cleaned and adjusted manually, which greatly reduces the overall operating speed of the production line and increases production costs. Moreover, the nail gun cartridges are easily damaged during the alignment and transfer process. The cartridges are usually made of metal materials, and during the transfer process, they frequently rub and collide with the transfer track, positioning components, etc., easily causing damage such as scratches and deformation on the surface of the cartridges. These damages not only affect the appearance quality of the cartridges, but may also affect the performance of the nail gun cartridges during subsequent use, such as reducing the shooting accuracy and reliability.

[0005] In summary, the problems of difficult positioning, low efficiency, and high damage rate existing in the alignment and transfer process of nail gun cartridges need to be solved urgently by researching and developing new transfer technologies and equipment to improve the overall level of nail gun cartridge production. Summary of the Invention

The flipping frame is provided with two symmetric fixed jigs, and the fixed jigs are provided with fixed slots for accommodating each plate; a connecting frame is arranged between the two fixed jigs, and the connecting frame is fixed to the output shaft of the flipping motor.

[0018] To ensure efficient and batch positioning of the cartridge cases of the nail guns during the whole-column conveying process, the cartridge cases are fixed in the sleeve plate by the whole-column conveying device of the present invention. As shown in the appendix Figure 1 The sleeve plate includes a bottom plate and a cover plate with openings. The bottom plate and the cover plate fix the cartridge cases in the middle. This not only avoids the misalignment of the cartridge cases during subsequent conveying, but also uses the sleeve plate as a conveying carrier, which is not only convenient and efficient for transportation, but also the sleeve plate avoids the friction and collision of the cartridge cases with the conveying track, positioning components, etc. during the conveying process, resulting in deformation or damage, and ensures the appearance quality of the cartridge cases. However, since the cartridge cases are in a stepped shape and have a greater weight at the bottom, they are usually in an upward-opening state when sorted by vibration. Therefore, the cartridge cases cannot be directly fixed into the sleeve plate; in view of this phenomenon:

[0019] The present invention uses a rocking plate as the whole-column conveying medium. First, a batch of disordered cartridge cases are sorted and arranged in the rocking plate by the whole-column sorting device, and then the rocking plate filled with cartridge cases is transported to the production conveying device. During the conveying process, the cartridge cases in the rocking plate are transferred to the sleeve plate through "covering the cover plate - flipping - removing the rocking plate - adding the bottom plate - flipping", realizing automatic and efficient whole-column conveying and improving production efficiency; and finally, the cartridge cases still remain in an upward-opening state, which is convenient for subsequent gunpowder filling.

[0020] This solution also has the following beneficial effects:

[0021] 1. Realize automatic whole-column conveying without manual participation: This solution constructs a complete set of automatic systems. Starting from the cartridge cases entering the storage bin of the whole-column sorting device, the intermittent feeding unit uses gravity guidance and mechanical cooperation to orderly feed the cartridge cases into the vibration sorting unit without manual intervention in the feeding link. The vibration sorting unit completes the sorting of the cartridge cases in the rocking plate quickly through a unique eccentric vibration design. In the production conveying device, the cartridge case conveying line and the sleeve plate conveying line operate in coordination, the intermittent transmission structure precisely controls the rhythm, and the cartridge case commutation mechanism and the flipping structure cooperate tacitly to complete the transfer and attitude adjustment of the cartridge cases from the rocking plate to the sleeve plate. The whole process does not require manual operation of the cartridge cases or adjustment of the equipment, completely getting rid of the dependence on manual labor and realizing full-process automatic whole-column conveying.

[0022] 2. Achieve stable, efficient, and continuous production: The design of each unit and mechanism is compact and reasonable. The intermittent feeding unit and the vibration sorting unit cooperate to efficiently complete the alignment and sorting of cartridge cases. In the production conveyor equipment, the intermittent drive structures of the cartridge case conveyor line and the template conveyor line precisely control the conveying rhythm. The cartridge case commutation mechanism and the flipping structure cooperate closely, reducing situations such as cartridge jamming and blockage. As the transmission carrier, the template not only ensures accurate positioning of the cartridge cases but also improves the transfer efficiency. The overall solution ensures that the production line can operate stably, efficiently, and continuously, significantly improving production efficiency.

[0023] 3. Improve the quality of nail gun cartridges: The design of fixing the cartridge case with the template effectively avoids the positioning deviation caused by the attitude change of the cartridge case during conveying, laying a foundation for the accurate operation of subsequent processes. At the same time, the template isolates the friction and collision between the cartridge case and the conveying track and positioning components. The protective designs in the alignment and sorting equipment, such as the guide components of the storage bin and the guide plates of the lifting feeding rack, reduce the risk of damage to the cartridge cases during pre-treatment, comprehensively ensuring the appearance quality and performance of the cartridge cases and significantly improving product quality.

[0024] 4. Achieve efficient, accurate, and automated feeding: The guide component inside the storage bin uses a unique inclined plate design, which is opposite to the inclination direction of the storage bin itself, forming a special gravity-guided area where the cartridge cases naturally tend to be arranged in an orderly manner. The automatic feeding switch of the lifting feeding rack is designed through a clever mechanical structure. The switch plate remains closed under its own weight. When the lifting feeding rack rises to a specific position, the limit block precisely changes the movement trajectory of the switch drive rod, automatically opening the switch plate to achieve automatic feeding of the cartridge cases. These series of structures cooperate closely, forming a coherent and efficient operation process from the storage, quantity control to the automatic feeding of the cartridge cases. This linkage mechanism not only reduces manual intervention and labor intensity but also greatly improves the feeding efficiency and accuracy, providing a stable and reliable material supply for the subsequent cartridge case sorting and conveying links.

[0025] 5. Achieve stable and intermittent template feeding: The template includes a bottom plate and a cover plate, which need to be alternately conveyed. The design of the intermittent template feeding mechanism breaks through the limitations of traditional template feeding methods. In the feeding structure, the intermittent feeding seat inside the unique fixed seat structure, with the cooperation of the upper and lower stop blocks and the intermediate gear drive structure, makes the movements of the two layers of stop blocks related and synchronous. Through the precise docking of the wedge block at the bottom of the upper stop block with the groove of the cover plate and the stepped groove at the top of the lower stop block with the bottom plate, stable intermittent feeding of the bottom plate and the cover plate is ensured. In the template feeding structure, the template feeding cylinder connects the two side feeding push plates through an intermediate plate. The thrust preventer on the feeding push plate uses the design of a rotating shaft and a torsion spring, which can effectively prevent the template from slipping back during the template feeding process, achieving precise and stable intermittent template feeding and effectively improving the efficiency and reliability of the entire production process.

[0026] 6. Achieve flexible and efficient connection and transfer: The intermediate transfer mechanism, as a key link between the whole-column sorting device and the production transfer device, plays a crucial role. The articulated design of the support frame and the support bracket, combined with the lifting cylinder at the bottom of the support bracket, enables it to flexibly adjust the height to adapt to the transfer requirements between different devices. The gathering structure and transfer structure on the support plate can quickly and effectively gather and transfer the cartridge cases, ensuring the smooth transition of the cartridge cases from the whole-column sorting device to the production transfer device and guaranteeing the continuity of the production line. At the same time, this mechanism fully considers the issue of space utilization in the design. Through the liftable support bracket and the compact layout of the gathering and transfer structures, while achieving efficient transfer, it minimizes the occupation of production space to the greatest extent.

[0027] The present invention also provides a technical solution: A method for whole-column transfer of special cartridge cases for nail guns, including the following steps:

[0028] Step 1: Arrange the cartridge cases in sequence with the openings upward in the rocking plate through the whole-column sorting device, and transfer the rocking plate filled with cartridge cases to the production transfer device.

[0029] Step 2: When transferring on the production transfer device, cover the rocking plate with a cover plate and then turn it 180°, so that the openings of the cartridge cases face downward.

[0030] Step 3: Remove the upper rocking plate, and then re-cover the bottom plate on the cartridge cases.

[0031] Step 4: Turn the bottom plate and the cover plate together 180°, so that the openings of the cartridge cases face upward.

[0032] Further, in the above step 3, before covering the bottom plate, it needs to be turned 180°.

[0033] Further, in the above step 3, after the rocking plate is removed, it is cyclically conveyed to the whole-column sorting device.

[0034] The beneficial effects of this solution:

[0035] 1. Precise whole-column sorting: With the help of the whole-column sorting device, the cartridge cases are arranged in an orderly manner with the openings upward in the rocking plate, solving the problems of difficult positioning and various postures of the cartridge cases in the traditional method, ensuring accurate operation in subsequent processes, and reducing the risk of equipment failure.

[0036] 2. Efficient transfer process: From the transfer of the rocking plate, covering and turning, to removing the rocking plate, re-covering the bottom plate and turning again, a series of steps are coherent and smooth, with a high degree of automation throughout the process, reducing manual intervention, greatly improving production efficiency, and meeting the needs of large-scale production.

[0037] 3. Ensure product quality: Through specific processes of stamping and flipping, avoid friction and collision between cartridge cases and equipment components during transmission, reduce surface scratches and deformation, ensure the appearance quality and internal performance of cartridge cases, and improve the product yield rate.

[0038] 4. Resource recycling: After the rocker plate is taken away, it is recycled and conveyed to the whole-column sorting equipment, realizing the repeated use of resources, reducing production costs, and enhancing the sustainability of the production system. Brief Description of the Drawings

A fixed shaft 26-1-7 is sleeved inside the gear 26-1-5, and both ends of the fixed shaft 26-1-7 are rotatably connected to the fixed seat 26-1-2. Limiting grooves are also formed at both ends of the fixed shaft 26-1-7, and limiting rings are installed in the limiting grooves to prevent the fixed shaft 26-1-7 from shifting along its axial direction.

[0072] In this embodiment, the intermittent transmission structure 23 is equivalent to the plate feeding structure 26-2. As Figure 10 shown, the plate feeding structure 26-2 includes a plate feeding cylinder 26-2-1 and feeding push plates 26-2-2 located on both sides of the plate feeding cylinder 26-2-1.

A stop component 27 is also provided on the sleeve plate conveyor line 22. As Figure 14 shown, it includes a stop cylinder 27-1 and an L-shaped stop block 27-2 connected to the end of the output shaft of the stop cylinder 27-1. A buffer block 27-3 is hinged on the stop block 27-2.

[0073] An intermediate conveying mechanism 3 is also provided between the alignment and sorting device 1 and the production conveyor device 2. As Figure 16 、 Figure 17As shown in the figure, the intermediate transfer mechanism 3 includes a support frame 31 and a carrier 32 hinged to one side thereof. A support plate 35 is provided at the top of the carrier 32, and a lifting cylinder 33 is provided at the bottom. A connecting slideway 34 is provided between the carrier 32 and the cartridge case conveying line 21. Along the transverse and longitudinal directions respectively on the support plate 35, a gathering structure 36 and a conveying structure 37 are provided.

A jacking cylinder 38 for driving it to lift up and down is provided at the bottom of the gathering structure 36. The conveying structure 37 includes a conveying plate 37-1 and a conveying cylinder 37-2.

[0074] Based on the above-mentioned alignment transfer device, this solution also provides an alignment transfer method dedicated to nail cartridges, including the following steps:

[0075] Step 1: Sequentially arrange the cartridges with the openings facing upward in the rocking plate through the alignment and sorting device 1, and transfer the rocking plate filled with cartridges to the production transfer device 2.

[0076] Step 2: When transferring on the production transfer device 2, cover the rocking plate with a cover plate and then turn it over 180°, so that the openings of the cartridges face downward.

[0077] Step 3: Remove the upper rocking plate, and then cover the cartridges with a bottom plate again.

[0078] Step 4: Turn the bottom plate and the cover plate together 180°, so that the openings of the cartridges face upward.

[0079] In step 3, before covering the bottom plate, it needs to be turned over 180°.

[0080] In step 3, after the rocking plate is removed, it is circularly conveyed to the alignment and sorting device 1.

[0081] Specific implementation process:

[0082] Alignment process:

[0083] Pour a number of cartridge cases into the storage bin 11-1. Place the rocking plate on the fixed frame 11-7. Start the drive motor 12-1 and drive the fixed frame 11-7 and the rocking plate on it to slide left and right and vibrate through the eccentric connecting piece. Then, the feeding cylinder 11-5 drives the lifting feeding frame 11-3 to move downward as a whole, so that the switch plate 11-6-1 is lower than the bottom of the inclined plate 11-2. The cartridge cases fall into the lifting feeding frame 11-3 under the action of the inclined plate 11-2 and gravity. Then, the feeding cylinder 11-5 drives the lifting feeding frame 11-3 to move upward until the top of the switch transmission rod 11-6-2 touches the limit block 11-11. Then, the lifting feeding frame 11-3 continues to move upward as a whole. The switch transmission rod 11-6-2 moves towards the feeding cylinder 11-5 direction, thereby driving the switch plate 11-6-1 to rotate outwards. The cartridge cases fall on the rocking plate through the material guiding groove. Under the vibration of the vibration sorting unit 12 and the action of the inclined gravity, the cartridge cases are arranged in order in the rocking plate;

[0084] After a certain period of time, when the rocking plate is filled with cartridge cases, the limit cylinder 11-9 near the intermediate conveying mechanism 3 drives the limit plate 11-8 to move obliquely downward to be lower than the fixed frame 11-7. At the same time, the lifting cylinder 33 of the intermediate transmission mechanism is started, so that the supporting bracket 32 rotates as a whole to be inclined in the same direction as the fixed frame 11-7. Then, the lifting and moving plate cylinder 11-10-1 drives the moving plate 11-10-3 to insert downward between the fixed frame 11-7 and the rocking plate. The lateral moving cylinder is started, and the rocking plate is driven to move laterally and gradually transferred from the fixed frame 11-7 to the supporting plate 35. After the transfer is completed, the lifting cylinder 33 drives the supporting bracket 32 to reset.

[0085] Conveying process:

[0086] The rocker plate on the supporting plate 35 is conveyed by the transfer cylinder 37-2 through the connecting slideway 34 to the loading station 001 of the cartridge case conveying line 21 and falls onto the feeding push plate 26-2-2. Synchronously with this process, the loading cylinder 11-5 of the intermittent plate feeding mechanism 26 on the sleeve plate conveying line 22 is activated, the stop block 26-1-4 located below is retracted, and the stop block 26-1-4 above extends to fix the cover plate. The bottom plate falls onto the feeding push plate 26-2-2. The feeding cylinder 26-2-1 conveys the bottom plate to the first plate taking station 007. Then the loading cylinder 11-5 is activated again and drives the stop block 26-1-4 to move in the reverse direction, causing the cover plate to fall onto the feeding push plate 26-2-2. Then the feeding cylinders 26-2-1 on the cartridge case conveying line 21 and the sleeve plate conveying line 22 are activated simultaneously and push the rocker plate, the cover plate and the bottom plate to move intermittently through the thrust stopper 26-3. The bottom plate continues to be conveyed forward, making the rocker plate located at the first plate adding station 002 and the cover plate located at the first plate taking station 007. At this time, the plate taking cylinder 24-4 located above the cover plate drives the mounting plate 24-5 to move downward so that the vacuum suction cup 24-6 adsorbs the cover plate. Then the transverse movement cylinder 24-3 is activated and drives the cover plate to move transversely above the rocker plate through the transfer rack 24-2 and cover the rocker plate with the cover plate.

[0087] The rocker plate and the cover plate continue to move forward as a whole into the fixed groove 25-4 of the flipping structure 25. The flipping motor 25-1 is activated to drive the whole flipping frame 25-2 to flip 180° so that the rocker plate is on the top. Then it continues to be conveyed to the rocker plate transfer station 004, and the rocker plate is taken away by the rocker plate transfer mechanism. Then it continues to be conveyed to the second plate adding station 005. The previous bottom plate has been flipped 180° by the flipping structure 25 on the sleeve plate conveying line 22 and is located at the second plate taking station 009. Similarly, the bottom plate is covered on the cover plate, and then is flipped by the flipping structure 25 so that the cover plate is at the bottom and the cartridge case opening is upward. Thus, the cartridge cases are sequentially aligned into the sleeve plates and conveyed, waiting to be transferred to the next process.
