Description

Technical Field

[0001] This invention relates to the field of automated sorting equipment technology, and more particularly to a pin sorting device. Background Technology

[0002] In the manufacturing industry, pin-type tools have many uses, including positioning, limiting, and fixing. Furthermore, pins come in various shapes to suit different needs. Multiple pins of different specifications may be used in the same process or on the same workpiece. Since these devices are generally not left in the product and are eventually removed during the process, it's easy for pins of different specifications to be mixed together. Because pins are generally small, manual sorting is time-consuming and labor-intensive. Therefore, how to efficiently and accurately sort pins of different specifications has always been a technical challenge in the field of pin sorting.

[0003] Traditional pin sorting methods often suffer from inefficiency, error-proneness, and an inability to handle pins of various sizes simultaneously. For example, some simple manual sorting methods not only consume a lot of manpower and time but also cannot guarantee accuracy; some mechanical sorting equipment has a complex structure, is inconvenient to operate, and cannot guarantee the orientation of pins of different diameters, leading to inaccurate subsequent sorting.

For those skilled in the art to which this application pertains, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0050] To address the aforementioned technical problems, this invention provides a pin sorting device, comprising three parts: a feeding section, an adjusting section, and a sorting section. The feeding section, through a circumferentially movable pushing component, straightens and ejects disordered pins 40. The adjusting section, by adjusting the movement of pins 40 of different diameters, evenly disperses them. The sorting section pushes the pins 40 to the corresponding sorting port 322 and places them into a storage device; those not corresponding to the specified size are pushed to the next sorting port 322 until sorting is complete. This technical solution enables efficient and accurate sorting of pins 40 of different sizes, significantly improving sorting efficiency and accuracy while reducing labor costs and error rates.

[0051] Please refer to Figure 1 This invention provides a pin sorting device, including a feeding section 10, an adjustment section 20, and a sorting section 30, which are arranged sequentially from top to bottom.

[0052] Specifically, the pin sorting device includes a base 100, on which a power rotating shaft 101 is provided, and also includes a housing 102 connected to the power rotating shaft 101. The housing 102 rotates with the power rotating shaft 101, while the base 100 does not rotate with the power rotating shaft 101.

[0053] Please refer to the reference. Figures 2 to 4The feeding section 10 includes a feeding trough 11 for receiving the pins 40 to be sorted. The feeding trough 11 is connected to the base 100 so that it does not rotate with the power rotating shaft 101. The bottom of the feeding trough 11 is provided with a discharge port 124. A pushing assembly 12 connected to the power rotating shaft 101 and capable of being driven to move in a circumferential direction is suspended above the feeding section 10. The pushing assembly 12 is composed of one or more pushing columns 122. When the power rotating shaft 101 applies power, the pushing column 122 moves along the circumferential rotation path, straightening the randomly stacked pins 40 and pushing them sequentially toward the discharge port 124.

[0054] It is understandable that the discharge port 124 corresponds to the rotation path of the push column 122. When the push column 122 rotates, it pushes the straightened sorting pins 40 into the discharge port 124 along the tangential direction of the rotation path.

[0055] In this embodiment, the driving component 12 includes:

[0056] A grid 121 for straightening randomly stacked pins 40 includes a plurality of columns arranged radially along the circumferential direction of movement; when the pushing assembly 12 moves in the circumferential direction, the randomly stacked pins 40 are straightened and arranged in the tangential direction of the circumferential direction of movement.

[0057] One or more push columns 122, and the feed trough 11 is provided with one or more discharge ports 124, the discharge ports 124 being arranged one-to-one on the rotation path of the push column 122; the push column 122 is used to push the straightened sorting pins 40 into the discharge ports 124 along the tangential direction of the rotation path when driven to rotate.

[0058] The feed trough is provided with multiple discharge ports 124, and the width of the discharge ports 124 increases sequentially along the rotation direction of the push assembly 12.

[0059] The pushing assembly 12 also includes one or more pushing columns 122, and the feeding trough 11 is provided with one or more discharge ports 124, which are arranged one-to-one on the rotation path of the pushing column 122. The pushing column 122 is used to push the straightened sorting pins 40 into the discharge ports 124 along the tangential direction of the rotation path when it is driven to rotate.

[0060] For example, such as Figure 3 As shown in the figure, a grid 121, a push column 122 disposed close to the power rotating shaft 101, and a discharge port 124 located on the tangent of the power rotating shaft 101 are shown.

[0061] Please continue to refer to this. Figure 1In this embodiment, a first connecting slide 123 is provided between the feeding part 10 and the adjusting part 20. Its surface is smooth and has an inclined angle to ensure that the pin 40 can be smoothly and quickly transferred from one part to the next part, reducing the damage to the pin 40 caused by jamming and collision.

[0062] Furthermore, the adjustment section 20 is provided with an inclined slide 21 for receiving and sorting pins 40, and the aforementioned first connecting slide 123 is connected between the discharge port 124 and the inclined slide 21.

[0063] Understandably, pins 40 are further divided into same-diameter pins 40 and different-diameter pins 40. Same-diameter pins 40 refer to pins 40 with the same diameter from beginning to end, resulting in a uniform thickness throughout the entire column. Different-diameter pins 40, on the other hand, have different diameters at different parts of the column, possessing a large end and a small end; that is, the thickness of the pin 40 varies at different locations. For example, a cylindrical pin 40 with a diameter that remains constant at 5 mm is a same-diameter pin 40; while a pin 40 with a diameter of 8 mm at one end and 5 mm at the other end is a different-diameter pin 40.

[0064] Please refer to the reference. Figure 1 , Figure 5 and Figure 6 In this embodiment, to achieve the sorting of pins 40 of the same diameter and pins 40 of different diameters, the inner side of the inclined slide 21 is divided into multiple isolation zones by multiple partition plates 23. The bottom of each isolation zone has a constricted opening to form an adjustment outlet 231, which corresponds one-to-one with the sorting components. Each isolation zone is provided with an adjustment column array, which consists of multiple equally spaced and independently rotatable adjustment columns 22. Specifically, the adjustment column 22 includes a threaded portion 221 that is threadedly connected to the inclined slide 21, and a smooth portion 222 with a smooth surface exposed to the outside, so as to achieve rapid passage of the pins 40.

[0065] By setting an adjustment column array to make the pins 40 fall in a dispersed manner, the pins 40 are prevented from rushing up and blocking the inclined slide 21, so that each pin 40 can pass through in sequence.

[0066] Based on this, when the pins 40 to be sorted slide down the inclined slide 21, under the action of the adjusting column array: for pins 40 of the same diameter, they can fall evenly after being discharged from the feed section 10; for pins 40 of different diameters, since they have large and small ends and the center of gravity is closer to the large end, if the large end is discharged first, the small end will fall with the large end down and the small end up due to the center of gravity being lower, and will fall evenly under the action of the pushing component 12; if the small end is discharged first, the large end will reverse its direction due to the influence of the center of gravity, and will eventually maintain the large end down and the small end up, and will also fall evenly under the action of the pushing component 12. This ensures the directionality of the pins 40 of different diameters, which is beneficial for accurate sorting in the future.

[0067] Specifically, the adjustment unit 20 rotates along with the power rotation shaft 101. Through the centrifugal force and friction generated by the rotation, it helps the pins 40 to achieve better uniform distribution and center of gravity adjustment within the adjustment column array, thereby achieving the purpose of motion posture adjustment. This ensures that pins 40 of different specifications can enter the subsequent sorting stage with the correct posture. It also makes the pins 40 more evenly distributed on the inclined slide 21, avoiding local accumulation or gaps, thus ensuring that each adjustment column array can fully play its role and improving the accuracy and stability of sorting. At the same time, the continuous rotational motion allows the pins 40 to continuously pass through the adjustment area, speeding up the processing speed and meeting the high efficiency requirements of pin 40 sorting in large-scale production.

[0068] Understandably, in practical applications, the rotation speed of the adjustment section 20 can be flexibly adjusted according to the actual working conditions such as the feeding speed and specification differences of the pin 40, in order to achieve the best adjustment effect.

[0069] In this embodiment, the function of the adjustment outlet 231 is to guide the pins 40, after being processed by the adjustment column array, to the corresponding sorting components. Specifically, pins 40 of different specifications enter the sorting components at their respective positions through the adjustment outlet 231, and are selectively discharged by the sorting port 322 in the sorting components according to the specifications of the pins 40, thereby completing the sorting of the pins 40. For example, the adjustment outlet 231 corresponding to a smaller specification pin 40 will guide it to a sorting component suitable for that specification, so that it can be accurately sorted out from the sorting port 322 of the corresponding width.

[0070] In this embodiment, a second connecting slide 31 is provided between the adjustment part 20 and the sorting part 30. Its surface is smooth and has an inclined angle to ensure that the pin 40 can be smoothly and quickly transferred from one part to the next part, reducing the damage to the pin 40 caused by jamming and collision.

[0071] Please refer to the reference. Figure 1 and Figure 7Furthermore, the sorting unit 30 includes multiple sorting components, each including a sorting ramp 321, which is connected to the second connecting chute 31.

[0072] The sorting ramp 321 has a portion that slopes downward in a first direction, so that when the pin 40 falls on the sorting ramp 321, it can be pressed against the sorting ramp 321 under the action of gravity; at the same time, the bottom of the sorting ramp 321 has a receiving surface for supporting the bottom end of the pin 40, which is in a second direction, so that the pin 40 can fall along the receiving surface and roll along the sorting ramp 321 as it falls.

[0073] Furthermore, the second connecting slide 31 is provided with a limiting groove corresponding to the adjustment outlet 231 of the adjustment section 20. The limiting groove is elongated and its bottom is connected to the sorting slope 321. The second connecting slide 31 is provided with an elongated limiting groove corresponding to the adjustment outlet 231 and its bottom is connected to the sorting slope 321, thereby ensuring that the pin 40 coming out of the adjustment outlet 231 can accurately enter the corresponding limiting groove, achieving precise guidance and reducing the possibility of the pin 40 deviating from the predetermined path; at the same time, the elongated shape can ensure that the pin 40 can accurately enter the corresponding limiting groove. The movement of pin 40 plays a certain constraining role, making it more stable during transmission, avoiding jumping or rolling, and ensuring that pin 40 enters the sorting ramp 321 in the expected posture and direction; in addition, the one-to-one correspondence setting can quickly and effectively guide pins 40 of different specifications to the corresponding sorting positions, reducing time waste in the sorting process, thereby improving the overall sorting efficiency. It can also reduce collisions between pins 40 and between pins 40 and the equipment, reduce the possible damage to pins 40, and ensure product quality.

[0074] Specifically, the first connecting slide 123, the inclined slide 21, and the second connecting slide 31 combine to form a cone shape. The advantages of this design are that the inclined angle utilizes gravity to allow the pins 40 to slide more smoothly and quickly from the feeding section 10 to the adjusting section 20, improving sorting efficiency. The smooth surface reduces friction between the pins 40 and the slides, preventing jamming or stagnation during transport and ensuring the continuity of the sorting process. Simultaneously, the conical structure helps to distribute the pins 40 from the feeding section 10 more evenly to various positions in the adjusting section 20, facilitating subsequent adjustment and sorting operations. Furthermore, the conical design is relatively compact, enabling effective pin transport and distribution within a limited space. Understandably, in large-scale industrial production, the conical and smooth inclined surface allows a large number of pins 40 to be transferred quickly and orderly from the feeding section 10 to the adjusting section 20, much like a production line, rapidly and stably advancing the production process.

[0075] In this embodiment, the sorting component also includes sorting openings 322 of different widths. Pins 40 of different specifications pass through the sorting openings 322 of the corresponding widths in sequence, thereby realizing the sorting of pins 40 and making the sorting process more orderly and efficient.

[0076] In this embodiment, the width of the sorting opening 322 increases sequentially along the sliding direction of the pin 40, and...

[0077] It is understandable that in the adjustment section 20, the pins 40 are dispersed and fall through the adjustment column array, so that the pins 40 pass through the inclined slide 21 in sequence, slide out through the multiple adjustment outlets 231 formed between two adjacent columns, and enter the corresponding limiting slide groove. Since the limiting slide groove is long and thin, the pins 40 can quickly pass through it and arrive at the sorting port 322 in a predetermined posture.

[0078] Specifically, in this embodiment, one sorting port 322 of each specification can be set, or multiple ports can be set at the same time.

[0079] If there is only one sorting port 322 of the same specification, then all pins 40 must pass through this sorting port 322 to complete the final sorting action. This means that pins 40 of the same specification need to queue up and pass through in sequence during sorting, resulting in reduced sorting efficiency. If there are multiple sorting ports 322 of the same specification, then multiple sorting ports 322 are used simultaneously, and pins 40 of the same specification do not need to queue up and pass through, which can effectively improve sorting efficiency.

[0080] In other words, the number of sorting ports 322 of the same specification in the bottom sorting ports 322 matches the number of limit chutes of the corresponding specification, thereby effectively improving sorting efficiency.

[0081] A separating protrusion 323 is provided between two adjacent sorting ports 322 to gather pins 40 that do not conform to the specifications of the sorting port 322 on the sliding path. Correspondingly, multiple discharge ports 124 correspond one-to-one with multiple sorting ports 322, and the width of the discharge port 124 is adapted to the width of the corresponding sorting port 322.

[0082] Understandably, the separation protrusion 323 can improve sorting accuracy. Since the width of the sorting port 322 increases sequentially, it can sort more accurately according to the specifications of the pins 40. The separation protrusion 323 can prevent pins 40 that do not conform to the specifications of the current sorting port 322 from falling prematurely, ensuring that each pin 40 can reach the sorting port 322 position that matches its specifications, avoiding confusion between pins 40 of different specifications. At the same time, it gathers pins 40 that do not conform to the specifications on the sliding path, which is convenient for subsequent unified processing or re-sorting, improving the integrity of the overall sorting work.

[0083] Please refer to Figure 8 and Figure 9 Furthermore, in this embodiment, the pin sorting device also includes a rotatable sorting pusher plate 33, which is connected to the housing 102 and can rotate with the power rotation shaft 101. The bottom side of the sorting pusher plate 33 contacts the sorting ramp 321, and can retract radially inward along the rotation circumference when the bottom side is squeezed. When the sorting pusher plate 33 is rotated, it climbs along the surface of the dividing protrusion 323 to push the pins 40 gathered at the dividing protrusion 323 past the dividing protrusion 323. The plate surface of the sorting pusher plate 33 is provided with a lifting hook portion 331, which provides a force to the pins 40 away from the sorting ramp 321 when the sorting pusher plate 33 pushes the pins 40.

[0084] Specifically, multiple lifting hooks 331 are provided, which can push the pin 40 from different positions to ensure the relative stability of the pin 40 during the entire lifting process, preventing significant tilting or irregular movement. This ensures the smoothness of the movement trajectory of the pin 40's geometric center and center of gravity during movement. It avoids uneven force distribution on the pin 40 due to single-point force application, which could lead to tilting or irregular movement, thus ensuring the pin 40 maintains a stable posture during the pushing process.

[0085] The lifting hook 331 is a right triangle, with its two right-angled sides corresponding to the surface of the sorting push plate 33 and the sorting inclined surface 321, respectively. When the sorting push plate 33 pushes the pin 40, the inclined side of the lifting hook 331 first contacts the pin 40 as the sorting push plate 33 moves forward.

[0086] Understandably, due to the inclination angle of the inclined side, an upward component force is generated on the pin 40. As the sorting pusher 33 continues to advance, the right-angled side of the lifting hook 331 of the right triangle contacts the pin 40. At this time, the upward component force reaches its maximum, thereby lifting the pin 40. This lifting action helps the pin 40 overcome the friction and possible adhesion between itself and the sorting inclined surface 321, ensuring that the pin 40 is effectively pushed past the separating protrusion 323 and enters the next sorting position or sorting port 322, thus improving the accuracy and efficiency of sorting.

[0087] For example, when the pin 40 is partially embedded in the small indentation of the sorting ramp 321 or fits tightly against the ramp, the lifting hook 331 can effectively lift it up, allowing it to smoothly enter the subsequent sorting process.

[0088] It is understandable that the lifting hook 331 can be in the following shapes besides a right-angled triangle: a semi-circle, where the arc-shaped surface can provide a smoother contact when pushing the pin 40, reducing damage to the pin 40, while also achieving a lifting effect; a trapezoid, where the short base of the trapezoid connects to the surface of the sorting push plate 33, and the long base corresponds to the sorting inclined surface 321, gradually increasing the lifting force on the pin 40 during the pushing process; a wedge, where the pointed end faces the direction of movement of the pin 40, effectively inserting below the pin 40 to achieve lifting; or a non-right-angled triangle, such as an acute or obtuse triangle, where the lifting effect is produced by contacting the pin 40 with the hypotenuse.

[0089] In this embodiment, the pushing component 12, the adjusting part 20, and the sorting pusher 33 are all connected to the power rotating shaft 101.

[0090] During operation, the mixed pins (type 40) are poured into the upper feed trough 11. The pushing column 122 moves circumferentially, causing the pins (type 40) to be stacked flat and move towards the center. The pins (type 40) are discharged from the discharge port 124 into the inclined slide 21. For pins (type 40) of the same diameter, they fall downwards normally, dispersed by the grid column assembly. For pins (type 40) of different diameters, their direction is adjusted by gravity according to the order in which the larger and smaller ends are discharged, ultimately keeping the larger ends at the bottom and the smaller ends at the top, and dispersed by the grid column assembly as they fall.

[0091] Specifically, after adjustment by the adjustment unit 20, the pin 40 type device slides to the sorting ramp 321 through the adjustment outlet 231 and the limiting chute. Pins 40 that meet the specifications of the sorting port 322 fall from the sorting port 322 to complete the sorting. Pins 40 that do not meet the specifications gather at the separating protrusion 323 and are pushed to the next sorting port 322 by the sorting push plate 33 to continue sorting until all sorting operations are completed. Pins 40 type devices that cannot be sorted are collected from the last empty sorting port 322.

[0092] The sorting component and the adjustment part 20 are detachably connected by a mortise and tenon structure 34, so that the sorting component can be replaced by plugging and unplugging to match the specifications of the sorting component with the pin 40 to be sorted.

[0093] In this embodiment, in the pin sorting device, following the principle of aperture priority, the sorting ports 322 in each sorting component are arranged in order of increasing aperture along the falling direction of the pin 40, that is, the sorting ports 322 with smaller apertures are located at the front end, and the sorting ports 322 with gradually increasing apertures are arranged sequentially at the rear.

[0094] Secondly, with the same aperture, the sorting openings 322 are arranged in ascending order of length along the falling direction of the pin 40. For example, for sorting openings 322 with an aperture of 5 mm, those with a length of 10 mm are placed at the front, and those with a length of 15 mm are placed after them.

[0095] For example, suppose there are pins 40 with apertures of 3 mm, 5 mm, and 8 mm, and lengths of 10 mm, 15 mm, and 20 mm, respectively. The sorting port 322 with an aperture of 3 mm and a length of 10 mm will be used first, followed by the sorting port 322 with an aperture of 3 mm and a length of 15 mm, and so on. For pins 40 with different apertures, such as pins 40 with an aperture of 5 mm at one end and 8 mm at the other, they will be processed after the pins 40 of the same aperture and length have been sorted. Pins 40 that cannot be matched to any existing sorting port 322 will ultimately fall into the last vacant sorting port 322 and be collected.

[0096] Furthermore, in this embodiment, after all the sorting ports 322 for sorting pins 40 of a specific size are arranged sequentially, the last sorting port 322 does not have a specific size specification. That is, this sorting port 322 can accept pins 40 of any size specification, thus forming an empty space without a specific sorting function. The purpose of this is to provide a centralized drop and collection point for pins 40 that cannot be sorted out by all the previous sorting ports 322 set according to specifications. This serves as a "safety net" collection area, facilitating the subsequent individual processing of these unsorted pins 40, such as manual identification or re-sorting them in the sorting process.

[0097] For example, if a total of 5 sorting ports 322 are set up for sorting pins 40 of different specifications, the first 4 have specific size specifications, while the 5th sorting port 322 forms a collection area for pins 40 without specific specifications, which is used to collect those pins 40 that cannot be sorted after the previous sorting process, so that they can be processed separately or re-sorted later.

[0098] Furthermore, multiple sorting ports 322 of the same specification can be arranged adjacent to each other. When a pin 40 slides down the sorting ramp 321, if a pin 40 that matches the specification of the current sorting port 322 fails to fall due to accidental factors, such as a collision with other pins 40 or instability in its own posture, the chances of it being correctly sorted by the subsequent adjacent sorting ports 322 of the same specification increase. For example, suppose that three adjacent sorting ports 322 of the same specification are set up for a certain specification of pin 40. If a pin 40 fails to fall due to a momentary jam when rolling past the first sorting port 322, it still has a high chance of being correctly sorted when passing through the second and third sorting ports 322, avoiding its continued sliding and potential confusion with other pins 40, or its incorrect entry into a larger sorting port 322 and being incorrectly sorted, thereby improving the error tolerance rate.

[0099] In addition, by reducing the interference that may be caused by individual pins 40 failing to fall in time at the corresponding sorting port 322 and continuing to slide down the slope, the possibility of needing subsequent processing or re-sorting is reduced, allowing more pins 40 to be accurately sorted during the first slide, thereby speeding up the entire sorting process.

[0100] Furthermore, the sorting unit 30 is connected to a collection trough, wherein each sorting component has a corresponding collection trough, which is used to collect the pins 40 falling from the sorting port 322, so as to collect the sorted pins 40.

[0101] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
