Description

Technical Field

[0001] The invention relates to the technical field of fastener material dividing and transporting devices, and in particular to a fastener material dividing and transporting device. Background Art

[0002] Fasteners, as an indispensable basic component in the industrial field, have a long history of development. In the early days, simple wooden mortise and tenon structures can be regarded as the prototype of fasteners. With the advancement of metal smelting technology, metal fasteners such as nails and bolts gradually appeared on the historical stage and were widely used in many industries such as construction and machinery manufacturing, greatly promoting the process of human industrialization. From the assembly of carriages to the construction of skyscrapers, fasteners are like joints in the "industrial skeleton", connecting various components tightly to ensure the stability of the overall structure.

[0003] The sorting and transportation of fasteners in the production process is a key link to ensure the smooth production process. The current fastener sorting system can be roughly divided into two categories: the first is the sorting of fasteners of the same specification, that is, with the help of automatic sorting mechanism, fasteners with exactly the same specifications and sizes are transported in order. This is mainly to facilitate the subsequent packaging operation and thus achieve accurate control of their quantity; the second is to classify fasteners of the same specification but different lengths, or different specifications and different lengths. Currently, it mainly adopts a combination of manual sorting and mechanical equipment sorting.

[0004] However, the second type of material sorting device has many disadvantages. As for manual sorting, it relies on workers' naked eye identification and manual sorting. Although it can screen fasteners of different specifications and sizes, fastener production is usually carried out in batches, and the quantity is extremely large. Manual sorting alone is not only inefficient, but also very easy to cause misclassification and omission due to worker fatigue, which in turn causes problems in the subsequent assembly process, affecting product quality, and also increasing the labor intensity of workers;

[0005] Looking at the material distribution of mechanical equipment, in order to prevent the fasteners from shifting during movement, their sliding tracks are often set to fixed custom sizes. This greatly reduces practicality, and batches of fasteners can only be distributed one by one. When distributing materials, in order to ensure that the fasteners can be fed in quickly and stably, the fasteners arranged near the block will continue to be squeezed by the fasteners on the back side, which causes individual fasteners to warp up, and even causes the distribution block to get stuck during operation, forcing workers to frequently stop the machine for maintenance, greatly reducing the efficiency of fastener distribution. Summary of the invention

[0006] The invention provides a fastener material dividing and transporting device, which improves the fastener material dividing efficiency, improves the practicability of the device, and reduces the labor intensity of workers.

[0007] The technical solution of the present invention is as follows:

[0012] Two turning plates, each of which is rotatably connected to the side of each clamping plate facing the inner wall of the screening housing. A row screening component is connected between the two turning plates, and the row screening component is used for screening the fasteners fed from the feeding port in a whole row;

[0013] A driving motor, which is fixedly connected to the outside of the screening housing, and the driving shaft of the driving motor is fixedly connected to one of the turning plates;

[0014] A discharging component for cooperating with the row screening component to adsorb and discharge the fasteners.

[0015] Further, the row screening component includes:

[0016] A number of positioning blocks. Two positioning grooves are opened on the turning plate.

The rectangular side surfaces of each positioning block are in contact with the inner walls of the guiding grooves. A transmission block is fixedly connected to each positioning block, and two clamping ropes are connected between the two transmission blocks for clamping the fed fasteners;

[0017] A number of turning gears, each of which is fixedly connected to the end far from the transmission block;

[0018] A lifting plate, which is slidably connected to the inner wall of the limiting housing. Two lifting plates are fixedly connected to the lifting plate, and two limiting toothed plates are fixedly connected to each lifting plate. The limiting toothed plates are used for positioning and turning the positioning blocks that move out of the guiding grooves;

[0019] A lifting electric cylinder, which is fixedly connected to the screening housing. A linkage plate is hinged between the telescopic shaft of the lifting electric cylinder and the lower side surface of the lifting plate.

[0020] Further, a lifting pad is fixedly connected to each of the lifting plates.

[0021] Further, an adjusting column is rotatably connected inside the transmission block, two adjusting blocks are threadedly connected to the adjusting column, an adjusting plate is fixedly connected to each of the adjusting blocks, and each adjusting plate is fixedly connected to each clamping rope;

[0022] A first gear is fixedly connected to the adjusting column, a second gear is meshed with one side of the first gear, and the second gear is rotatably connected to the transmission block;

[0023] A first motor is fixedly connected inside the transmission block, and a driving shaft of the first motor is fixedly connected to the second gear.

[0024] Further, the discharging assembly includes two limiting frames fixedly connected between the inner side of the screening housing and the outer side of the limiting housing.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0044] Embodiment

[0045] Such as Figures 1 to 9As shown in the figure, this embodiment provides a fastener sorting and transporting device, which includes a screening housing 11, a conveying table 16, two clamping plates 18, two flipping plates 110, a driving motor 1, and a discharging assembly. The feeding port 12 is fixedly connected to the screening housing 11 and is used to orderly feed fasteners into the screening housing 11. The limiting housing 13 is fixedly connected inside the screening housing 11. The first discharging port 14 is opened on the lower side of the limiting housing 13. The cavity between the screening housing 11 and the limiting housing 13 is the second discharging port 15, which is used to sort and transport the fasteners screened out from the first discharging port 14 and the second discharging port 15. The conveying table 16 is fixedly arranged on the lower side of the screening housing 11. The surface of the conveyor belt on the conveying table 16 is provided with screening rubber strips 17 arranged vertically and horizontally. Through the screening rubber strips 17 arranged vertically and horizontally, several separate storage cavities are formed on the surface of the conveyor belt on the conveying table 16, which are used to gather and convey the fasteners that fall at different times. Each clamping plate 18 is fixedly connected to the inner wall of the screening housing 11. The gap between each clamping plate 18 and the limiting housing 13 is the guiding groove 19. Each flipping plate 110 is rotatably connected to the side of each clamping plate 18 facing the inner wall of the screening housing 11. The row screening assembly is connected between the two flipping plates 110. The row screening assembly is used to screen the fasteners fed from the feeding port 12 in a whole row. The driving motor 1 is fixedly connected to the outside of the screening housing 11. The driving shaft of the driving motor 1 is fixedly connected to one of the flipping plates 110. The discharging assembly is used to cooperate with the row screening assembly to adsorb and discharge the fasteners;

[0046] The number of fasteners fed into the feeding port 12 each time is controlled by an externally connected vibrating disk counting and sorting machine. Since this is a commonly used technical means in the art, it will not be elaborated here. Then, the fasteners are arranged in a row by the row screening assembly. A number of neatly arranged fasteners are quickly screened out under the linkage cooperation of the row screening assembly and the discharging assembly, and then fall on the conveying table 16 for conveying. Compared with the prior art where the neatly arranged fasteners are sorted one by one, this solution improves the sorting efficiency of the fasteners, enables the fasteners to be sorted more quickly. At the same time, this solution can not only sort the fasteners with the same specification, the same diameter but different lengths, but also sort the fasteners with different specifications, the same diameter but different lengths, improves the practicability of the device, reduces the manual sorting operation of the fasteners, and reduces the labor intensity of the workers.

[0047] As Figures 1 to 8As shown, the screen assembly includes a plurality of positioning blocks 21, two positioning grooves 111 are provided on the flip plate 110, the cylindrical side surfaces of each positioning block 21 are slidably connected with the inner wall of the adjacent positioning groove 111, the rectangular side surfaces of each positioning block 21 are abutted with the inner wall of the guide groove 19, each positioning block 21 is fixedly connected with each transmission block 22, two positioning ropes 23 are connected between the two transmission blocks 22, and are used to position the fasteners fed in, and the axes of the two positioning ropes 23 are always kept parallel;

[0048] Through the guide groove 19, when the positioning block 21 driven by the flip plate 110 moves in the guide groove 19, the angle between the positioning block 21 and the horizontal working surface of the screening material shell 11 remains unchanged, so that the rows of fasteners will not deflect and fall off during the movement, ensuring the stability of the device. Each flip gear 24 is fixedly connected to the end away from the transmission block 22, the lifting plate 25 is slidingly connected to the inner wall of the limit shell 13, two lifting plates 26 are fixedly connected to the lifting plate 25, and two limit tooth plates 27 are fixedly connected to the lifting plate 26. The limit tooth plate 27 is used to position and flip the positioning block 21 moved out of the guide groove 19, and the lifting electric cylinder 28 is fixedly connected to the screening material shell 11. The linkage plate 281 is hinged between the telescopic shaft of the lifting electric cylinder 28 and the lower side of the lifting plate 25;

[0049] The clamping rope 23 in the screen assembly is composed of a number of electromagnetic coils and copper wires arranged at intervals. The fasteners dropped on the two clamping ropes 23 are energized in sequence by the electromagnetic coils to generate an alternating magnetic field, so that the fasteners move along the rope direction under the action of the magnetic field force. By controlling the energization sequence of the electromagnetic coils and the magnetic field strength, the moving direction and speed of the screws can be accurately controlled;

[0050] In addition, the relative height between the two positioning blocks 21 in the screen assembly can also be changed, so that the positioning rope 23 is in an inclined state, tilting downward from one end close to the feed port 12, so that the fasteners falling on the positioning rope 23 can slide along the positioning rope 23 to a relatively lower end by their own weight;

[0051] By using the high-precision telescopic characteristics of the lifting electric cylinder 28, the upward movement distance of the lifting plate 25 is accurately controlled, and the fasteners of different sizes on the clamping rope 23 can be quickly detached from the clamping rope 23 by the upward movement of the lifting plate 25, and then quickly fall out of the screening shell 11 through the first discharge port 14 or the second discharge port 15 along the notches between the lifting plates 25 or the notches on both sides of the limiting shell 13, so that the conveying platform 16 can quickly collect fasteners of different sizes in batches;

[0052] In addition, when all fasteners except the smallest-sized ones have been screened out, the upward movement of the lifting plate 26 will drive the limit tooth plate 27 to engage with the adjacent flipping gear 24, and then drive the positioning block 21 to flip towards the notch at the center of the jacking plate 25, enabling the smallest-sized fasteners to fall out of the first discharge port 14 in a whole batch, thus completing the rapid batch separation operation. At the same time, the limit tooth plate 27, through its engagement with the flipping gear 24, also limits the angle between the positioning block 21 and the screening housing 11, enabling the positioning block 21 to be angle reset when it moves downward, so that the subsequent falling fasteners can move smoothly;

[0053] That is, through the action of the alternating magnetic field, the row screening assembly arranges a number of fasteners falling into the screening housing 11 in an orderly manner in a row. Then, by controlling the rotation of the flipping plate 110, the arranged fasteners move downward, causing the unloaded clamping rope 23 on the other side to lift upward, enabling the lifted clamping rope 23 to further carry the newly fed fasteners, improving the screening efficiency of the device. The fasteners that have moved downward and are arranged are precisely driven by the lifting electric cylinder 28 to move upward in sequence according to their lengths. When the fasteners of the same size move upward, at this time, through the electromagnetic attraction effect of the discharge assembly, the relatively upward-moving fasteners are adsorbed, and then these fasteners will disengage from the clamping rope 23. Finally, in cooperation with the discharge assembly, the fasteners of the same size in a single batch are quickly screened out, improving the screening efficiency and effect of the fasteners.

[0054] As Figures 3 to 8 shown, each lifting pad 29 is fixedly connected to each lifting plate 26;

[0055] The lifting pad 29 is used to replace the wear between the surface of the lifting plate 26 and the lower end of the fastener. At the same time, preferably, the material of the lifting pad 29 is rubber. Due to the relatively soft and wear-resistant characteristics of the rubber material itself and the relatively large surface friction, when the lifting pad 29 moves upward, the bottom end of the fastener will not slip on the upper surface of the lifting pad 29, enabling the lifting pad 29 to move upward and the fasteners of the same size to quickly disengage from the clamping rope 23, improving the separation effect of the fasteners.

[0056] As Figure 7 shown, the adjusting column 221 is rotatably connected to the transmission block 22. The adjusting column 221 is threadedly connected to two adjusting blocks 222. Each adjusting block 222 is fixedly connected to each adjusting plate 223, and each adjusting plate 223 is fixedly connected to each clamping rope 23. The adjusting column 221 is fixedly connected to the first gear 224. One side of the first gear 224 meshes with the second gear 225. The second gear 225 is rotatably connected to the transmission block 22. The first motor 226 is fixedly connected to the transmission block 22, and the drive shaft of the first motor 226 is fixedly connected to the second gear 225;

[0057] It is driven synchronously by the first motors 226 on the two side driving blocks 22, thereby changing the axial center distance between the two positioning ropes 23, and then cooperating with fasteners of different specifications for use, improving the practicability of material separation.

[0058] Such as Figures 2 to 5 shown, the linkage column 42 is coaxially and fixedly connected between the two flipping plates 110, and the linkage column 42 is rotatably arranged on the limiting housing 13;

[0059] Through the linkage column 42, the synchronous transmission relationship of the two side flipping plates 110 is made more precise, and at the same time, the procurement of motor driving parts can be reduced, and the use cost can be lowered.

[0060] Such as Figures 2 to 3 and Figures 8 to 9 shown, the discharging assembly includes two limiting frames 31, the two limiting frames 31 are fixedly connected between the inner side of the screening housing 11 and the outer side of the limiting housing 13, each linkage column 32 is rotatably connected in each limiting frame 31, two transmission discs 33 are fixedly connected to the linkage columns 32, the non - center positions on each transmission disc 33 are hinged to the feeding plate 34, the feeding plate 34 is in sliding contact with the inner wall of the limiting housing 13, the electromagnetic plate 35 is fixedly connected to the lower side of the feeding plate 34, each linkage column 32 is fixedly connected to each third gear 36, the third gear 36 meshes with the fourth gear 37, the fourth gear 37 is rotatably connected to the limiting frame 31, and the second motor 38 is fixedly connected to the limiting frame 31, and the driving shaft of the second motor 38 is fixedly connected to the fourth gear 37.

[0061] The electromagnetic plate 35 adsorbs the lifted fasteners, and then under the relative movement of the feeding plate 34 and the limiting housing 13, the screws that are squeezed off pass through the notches on the left and right sides of the limiting housing 13, and thus through the second discharging port 15, and fall on the lower conveying table 16, so that the fasteners of different sizes screened step by step all discharge through one side outlet on the screening housing 11, which is convenient for workers to distinguish the screened fasteners, and then transfer these fasteners, improving the discharging precision of the fasteners and facilitating the collection of fasteners of different sizes by workers.

[0062] Such as Figure 2 and Figure 8 shown, two guiding plates 41 are respectively fixedly connected to the inner walls of the long axes on both sides of the limiting housing 13;

[0063] Through the guiding plates 41, the screws adsorbed by the electromagnetic plate 35 pass through the relative movement between the feeding plate 34 and the inner wall of the limiting housing 13, and then are squeezed off by the inner wall of the limiting housing 13 and fall along the guiding plates 41, thus falling into the second discharging port 15, further improving the precision of fastener material separation.

[0064] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
