Description

Technical Field

[0001] The present invention belongs to the technical field of nail sorting, and specifically relates to a nail sorter for automatic punching and nailing of toy boards. Background Art

[0002] In the production of toy boards, the punching and nailing process is crucial, and the previous nail sorting link directly affects production efficiency and product quality. At present, as a key device for nail sorting, the nail sorter has many problems that need to be solved urgently.

[0003] Vibration is an important way for the nail sorter to work. However, when the existing equipment vibrates, the sorted nails are likely to scatter again. For example, in the common nail sorter structure, after the nails are sorted and arranged vertically, vibration will cause their positions to shift or even fall down. Operators need to sort them repeatedly, which greatly wastes time and manpower, seriously reduces the nail sorting efficiency, and slows down the production progress of toy boards. Moreover, most nail sorters rely on motor vibration, and the continuous force generated by the motor rotation in a single direction causes the nails to be easily stuck. For example, in a vibrating disk type nail sorter, when the nails rise along the spiral track, due to the fixed vibration direction of the motor, they often get stuck at the turns or narrow parts of the track. The jamming of nails not only interrupts the conveying, but may also cause a chain reaction, resulting in equipment shutdown. Frequent jamming reduces production efficiency, increases equipment maintenance costs, and shortens the service life of the equipment. In addition, there are also defects in the feeding link. After the staff pour the nails into the storage device, the nails are likely to accumulate when entering the nail sorter. The accumulation of materials not only wastes nails, but may also block the passage, interfere with the vibrating components and transmission tracks, reduce the nail sorting accuracy and efficiency, and even cause equipment failures, which is not conducive to the large-scale production of toy boards.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0039] Embodiment 1:

[0040] As Figures 1 to 10 shown, a nail sorting device for automatic punching and nailing of a toy board includes a storage barrel 1.

[0041] A lifting and slow unloading assembly is installed inside the storage barrel 1. The lifting and slow unloading assembly includes a lead screw 22 and a matching lead screw sleeve 222. An outer wall of the lead screw sleeve 222 is provided with a sleeve 23, and a conical lifting plate 24 is movably installed on an inner side wall of the sleeve 23. A seesaw 25 is rotatably installed on the lead screw sleeve 222. One end of the seesaw 25 is connected to a bottom of the lifting plate 24, and the other end is adapted to a top cover 26 installed on a top of the lead screw 22; this design enables the lifting plate 24 to be driven to operate accurately and stably when the lead screw sleeve 222 rises. The advantage is that it can ensure that the nail bolts placed in the space formed by the sleeve 23 and the lifting plate 24 will not be in chaos, collide and deform due to shaking or sudden displacement during the rising process, greatly improving the stability during the nail bolt conveying process and laying a foundation for subsequent efficient nail sorting.

[0042] A collar 3 connected to the lead screw is installed inside the storage barrel 1. An L-shaped baffle 32 is installed on the collar 3, and a magnetic attraction ring 321 for adsorbing an end face of a nail bolt is installed on the L-shaped baffle 32; the magnetic attraction ring 321 can quickly and firmly adsorb and fix the nail bolt after it is sorted into a vertical state, avoiding the displacement of the nail bolt due to factors such as vibration and rotation during the operation of the equipment, greatly improving the stability and accuracy of the nail bolt sorting, providing a neat and stable arrangement of nail bolts for the subsequent automatic punching and nailing process, and effectively reducing the defective rate.

[0043] A separation plate 4 is slidably installed inside the collar 3. A notch 41 adapted to the magnetic attraction ring is provided on the separation plate 4. A pressure rod 43 vertically inserted into the collar is installed on the side wall of the separation plate 4. A number of pairs of protrusions 433 are installed inside the storage barrel 1, and the heights of adjacent protrusions are different. The protrusion 433 is slidably connected to the pressure rod 43 and is used to change the vibration amplitude of the separation plate 4. By changing the vibration amplitude of the separation plate 4 with protrusions 433 of different heights, the advantage is that it can effectively avoid the problems of mutual interference and aggregation caused by the same vibration frequency of the nail bolts, and can adjust the positions of the nail bolts more carefully and comprehensively, further improving the sorting effect of the nail bolts and meeting the strict requirements of the automated punching and nailing process for the neatness of the nail bolts.

[0044] As Figures 1 to 10 shown, in the specific implementation, a bottom 11 is provided at the bottom of the storage barrel 1, and an installation groove 113 is provided on the bottom 11. The storage barrel 1 is sleeved in the installation groove 113, and the storage barrel 1 and the bottom 11 are connected by screwing bolts. This connection method facilitates the assembly and disassembly of the equipment, is convenient for cleaning, maintaining the interior of the equipment and replacing parts in the later stage, and greatly improves the maintainability of the equipment. Four support legs 111 are installed on the bottom 11, and reinforcing ribs 112 with different heights are installed between adjacent support legs 111. The reinforcing ribs 112 not only enhance the structural strength of the bottom 11, improve the overall stability of the equipment, and reduce the shaking caused by factors such as vibration during operation, but also the design of different heights can adapt to different placement planes, enhancing the environmental adaptability of the equipment.

[0045] As Figures 1 to 10 shown, further, a pair of fixed seats 121 are symmetrically installed on the outer side wall of the storage barrel 1. A suspension ring 12 is rotatably installed on each of the pair of fixed seats 121, and an anti-slip sleeve is installed on the suspension ring 12. The setting of the suspension ring 12 facilitates the lifting operation of the equipment during handling and installation, improves the convenience of equipment handling, and the anti-slip sleeve increases the friction during lifting, preventing slipping between the lifting tool and the suspension ring 12, and greatly improving the safety during lifting.

[0046] Embodiment 2:

[0047] Based on Embodiment 1, the difference from this embodiment is: As Figures 1 to 10As shown in the figure, a mounting base 221 is provided at the bottom of the bucket 11, and the mounting base 221 is connected to one end of the lead screw 22. The other end of the lead screw 22 is installed with a synchronous shaft 2, and a crank 21 is installed on the synchronous shaft 2. A handle 211 is installed on the crank 21. A positioning frame 212 is rotatably installed on the synchronous shaft 2, and the positioning frame 212 is installed on the side wall of the storage bucket 1. Through structures such as the crank 21 and the synchronous shaft 2, the operator can manually and precisely control the rotation of the lead screw 22. Compared with other complex driving methods, this manual operation method has a lower cost, and the operator can flexibly adjust the rotation speed and force according to the actual situation of nail bolt sorting, enhancing the flexibility and controllability of equipment operation.

[0048] As Figures 1 to 10 shown, in the specific implementation manner, telescopic sleeves 225 are installed on both end faces of the lead screw sleeve 222. The telescopic sleeves 225 are made of flexible materials, and the telescopic sleeves 225 are placed outside the lead screw 22 to protect the lead screw 22. The telescopic sleeves 225 can effectively block impurities such as dust and debris from entering the fitting clearance between the lead screw 22 and the lead screw sleeve 222, reduce equipment failures caused by wear of impurities, greatly extend the service life of the lead screw 22 and the lead screw sleeve 222, and reduce the equipment maintenance cost. A limiting plate 223 is installed on the side wall of the lead screw sleeve 222. A limiting rod 224 is movably installed through the inside of the limiting plate 223, and the bottom of the limiting rod 224 is installed on the bottom of the bucket 11. The cooperation between the limiting rod 224 and the limiting plate 223 can limit the movement track of the lead screw sleeve 222, ensure that the lead screw sleeve 222 can only move up and down stably along the axial direction of the lead screw 22, and further improve the stability and reliability of equipment operation.

[0049] As Figures 1 to 10As shown in the figure, further, a conical baffle 231 is installed at the bottom of the sleeve 23. The end of the conical baffle 231 is connected to the side wall of the lead screw sleeve 222. And a vertically arranged guide rail 232 is installed on the inner side wall of the sleeve 23. Limit blocks 233 are installed at both ends of the guide rail 232. And the guide rail 232 is slidably connected to the lifting plate 24. And the limit blocks 233 are used to prevent the lifting plate 24 from disengaging from the guide rail 232. The guide rail enables the lifting plate to lift stably, ensuring the smooth conveying of the nail bolts; the limit blocks prevent the lifting plate from disengaging from the guide rail, ensuring the safe and stable operation of the equipment. A clamping seat 252 is installed on the side wall of the lead screw sleeve 222. And the clamping seat 252 is L-shaped. A clamping shaft 253 is installed inside the clamping seat 252. And the clamping shaft 253 is connected to the rotation center of the toggle plate 25. A torsion spring 254 is sleeved on the clamping shaft 253. One end of the torsion spring 254 is clamped on the toggle plate 25, and the other end is clamped on the clamping seat 252. A strip-shaped groove 251 is opened on one side surface of the toggle plate 25. A sliding rod 242 is slidably arranged on the strip-shaped groove 251. Vertical plates 241 are installed at both ends of the sliding rod 242. The ends of the vertical plates 241 are connected to the lifting plate 24. The setting of the torsion spring 254 enables the toggle plate 25 to automatically reset when not affected by the top cover 26, ensuring that every time the lead screw sleeve 222 rises, the toggle plate 25 can accurately cooperate with the top cover 26 to drive the lifting plate 24 to work, improving the coherence and stability of the equipment operation. At the same time, the sliding connection mode of the sliding rod 242 in the strip-shaped groove 251 makes the upward movement of the lifting plate 24 smoother and more accurate, which is beneficial to evenly push the nail bolts upward and realize automatic blanking.

[0050] Embodiment 3:

[0051] Based on Embodiment 2, the difference from this embodiment is that: As Figures 1 to 10 shown in the figure, a synchronous frame 33 is installed on the side wall of the collar 3. The synchronous frame 33 is connected to the side wall of the top cover 26. A sliding sleeve 31 is installed at the central position of the collar 3. The sliding sleeve 31 is placed in the central missing hole of the separation plate 4. A pressing plate 311 is installed on the sliding sleeve 31. The bottom of the pressing plate 311 is attached above the separation plate 4. And the upper surface of the pressing plate 311 is inclined. The synchronous frame 33 can ensure that the actions of the collar 3 and the lead screw 22 are synchronized, enabling the separation plate 4 to accurately rotate and vibrate when the lead screw 22 rotates, improving the consistency of the collaborative work of each component of the equipment. The inclined upper surface design of the pressing plate 311 can guide the nail bolts falling onto the separation plate 4 to move more smoothly to the surroundings under the action of centrifugal force, further improving the efficiency and effect of nail bolt sorting.

[0052] As Figures 1 to 10As shown, in the specific implementation, an inclined surface 42 is provided on the upper surface of the separation plate 4. A connecting frame 44 is installed at the bottom of the separation plate 4. The connecting frame 44 is L-shaped and penetrates through the side wall of the collar 3. The connecting frame 44 is connected to the pressure rod 43, and a guide wheel 431 is installed at the end of the pressure rod 43. The guide wheel 431 is in mutual fit with the surface of the protrusion 433. A positioning ring 432 is installed at the bottom of the protrusion 433, and the positioning ring 432 is installed on the side wall of the storage barrel 1. The design of the inclined surface 42 helps the nail bolts to disperse and slide better on the separation plate 4, improving the efficiency of nail bolt sorting. The guide wheel 431 is in fit with the surface of the protrusion 433. Compared with direct sliding, the guide wheel 431 can reduce the friction between the pressure rod 43 and the protrusion 433, reduce component wear, extend the service life of the equipment, and at the same time make the sliding of the pressure rod 43 on the protrusion 433 smoother, ensuring the stability and continuity of the vibration of the separation plate 4.

[0053] As Figures 1 to 10 shown, further, a guide groove 442 is provided on the side wall of the collar 3. A guide rod 443 is installed at the end face of the guide groove 442. A guide block 441 is slidably arranged on the guide rod 443, and the side wall of the guide block 441 is slidably connected to the side wall of the guide groove 442. The guide block 441 is connected to the connecting frame 44. A tension spring 444 is sleeved on the guide rod 443. One end of the tension spring 444 is clamped on the guide block 441, and the other end is clamped on the end face of the guide groove 442. The cooperation of the guide groove 442, the guide rod 443 and the guide block 441 can play a good guiding role in the movement of the connecting frame 44, ensuring the stability and accuracy of the separation plate 4 during vibration. The tension spring 444 can provide a resetting pulling force for the separation plate 4 when the pressure rod 43 leaves the protrusion 433 at a relatively high position, further optimizing the vibration effect of the separation plate 4, enabling it to more effectively adjust the position of the nail bolts and improving the quality of nail bolt sorting.

[0054] The implementation principle of a nail sorting device for automatic punching and nailing of a toy board according to the present invention is as follows:

[0055] The operator first puts the nail bolts in the toy board processing into the storage barrel 1. At this time, a part of the nail bolts will enter the space formed by the sleeve 23 and the lifting plate 24.

[0056] Next, the operator manually rotates the handle 211, driving the crank 21 to rotate. The crank 21 then drives the synchronous shaft 2 to rotate, thereby causing the lead screw 22 to start rotating. Since the lead screw 22 and the lead screw sleeve 222 are mutually adapted, the rotation of the lead screw 22 pushes the lead screw sleeve 222 to move up and down along the axial direction of the lead screw 22. This cooperative design of the lead screw and the lead screw sleeve has high stability and precision, ensuring that the lead screw sleeve 222 moves smoothly along the lead screw 22, providing a solid foundation for the orderly operation of subsequent components, guaranteeing the smoothness of the entire nail sorting process, reducing nail sorting errors caused by component shaking or displacement, and greatly improving the working reliability of the nail sorter.

[0057] During the upward movement of the lead screw sleeve 222, when the lead screw sleeve 222 drives the sleeve 23 to gradually move to the end face of the separation plate 4, the top cover 26 at the top of the lead screw sleeve 222 begins to approach one end of the rocker 25. As the lead screw sleeve 222 continues to rise, the top cover 26 pushes the rocker 25 to rotate around the clamping shaft 253. The other end of the rocker 25 slides in the strip groove 251 through the slide bar 242, thereby driving the vertical plate 241 and the lifting plate 24 connected thereto to move upward. Since the lifting plate 24 is conical and movably installed on the inner side wall of the sleeve 23, and the rising speed of the lifting plate 24 is relatively slow, the nail bolts in the space formed by the sleeve 23 and the lifting plate 24 move up slowly synchronously. Also, due to the inclined state of the lifting plate 24, the ejected nail bolts will automatically scatter in all directions, realizing automatic blanking, and the falling nail bolts just land on the separation plate 4. The slowly rising lifting plate 24 can not only gently push the nail bolts to avoid deformation or chaos of the nail bolts caused by rapid movement, but also its inclined state makes the nail bolts fall evenly and dispersedly, greatly improving the uniformity of the distribution of the nail bolts on the separation plate 4, creating favorable conditions for the subsequent efficient sorting of the nail bolts, and effectively improving the nail sorting efficiency and quality.

[0058] Meanwhile, when the lead screw 22 rotates, the collar 3 is driven to rotate by the synchronizing frame 33, and the collar 3 then drives the separation plate 4 to rotate synchronously. When the separation plate 4 rotates, the centrifugal force generated is used to drive the studs that have just fallen onto the separation plate 4 to move around. Eventually, the stud shafts of the studs can pass through the notches 41 on the separation plate 4, while the stud heads are located above the separation plate 4, making the studs vertical. At this time, the magnetic attraction ring 321 installed on the L-shaped baffle 32 of the collar 3 comes into play, and the studs that have been sorted and are in a vertical state are adsorbed by the magnet and fixed firmly in their corresponding positions. During the subsequent rotation of the separation plate 4, the pressure rod 43 installed on the side wall of the separation plate 4 slides along the protrusions 433 inside the storage barrel 1. Here, the heights of several pairs of protrusions 433 provided inside the storage barrel 1 are different. When the pressure rod 43 slides along these protrusions 433 with different heights, it drives the separation plate 4 to vibrate. The protrusions 433 with different heights cause the amplitude of the vibration of the separation plate 4 driven by the pressure rod 43 to change, thereby reducing the possibility of the same vibration frequency of the studs, effectively avoiding situations such as mutual interference and aggregation of the studs due to the same vibration frequency, which are not conducive to sorting. And because the studs are firmly adsorbed by the magnet, this vibration will not affect the sorted studs, and the sorted studs will not be ejected due to the vibration, ensuring that the sorting effect of the studs is not disturbed, further adjusting the positions of the studs, and ensuring that the studs are in an ideal sorting state. This design that combines the magnetic attraction ring and the vibrating separation plate, on the one hand, ensures the stability of the sorted studs through magnetic attraction fixation, and on the other hand, precisely adjusts the positions of the remaining studs by vibration, greatly improving the accuracy and success rate of stud sorting, meeting the extremely high requirements for the neatness of studs in the automated punching and nailing process, reducing the defective rate, and improving the product quality.

[0059] And since the separation plate 4 is always in a vibrating state, when the separation plate 4 is at the bottommost position, the distance between the stud head and the separation plate 4 is relatively large. This design enables the operator to more conveniently pick up the studs with their fingers, improving the convenience in actual operation and providing an orderly supply of studs for the subsequent automated punching and nailing process. The relatively large distance design fully considers the convenience of manual operation, reduces the obstacles and the risk of misoperation when the operator picks up the studs, improves the efficiency of the coordinated work between the manual labor and the equipment, and especially when manual assistance for loading and unloading or handling special situations is required, it can significantly improve the overall work efficiency.

[0060] After completing a round of sorting, reverse the screw rod shaft to reset it. During the reverse rotation of the screw rod shaft, the synchronizing shaft 2, the crank 21, and the screw rod 22 rotate in the opposite direction, driving the screw rod sleeve 222 to descend along the axial direction of the screw rod 22. At the same time, due to the reverse rotation of the screw rod 22, the rotation direction of the collar 3 and the separation plate 4 driven by the synchronizing frame 33 also changes accordingly. This change in the rotation direction causes the pins that may have been jammed during the preliminary sorting process to be subjected to forces in different directions from before. The pins that were originally stuck in a specific position due to centrifugal force and vibration have the opportunity to change their posture or position under the action of the new rotational force, freeing themselves from the jammed state, further improving the comprehensiveness and accuracy of pin sorting, and ensuring that the pin sorter continuously and efficiently supplies the sorted pins stably for the automated punching and nailing process. The processing mechanism for jammed pins during the reverse reset of the screw rod shaft greatly enhances the ability of the pin sorter to handle complex pin states, avoids equipment failures or incomplete pin sorting caused by individual jammed pins, extends the service life of the equipment, ensures that the equipment can always maintain high-efficiency and stable pin sorting performance during long-term high-intensity work, and provides a strong guarantee for the continuity of automated production.
