Description

Technical Field

[0001] This invention relates to the field of parts manufacturing technology, and more specifically, to a material feeding system and method. Background Technology

[0002] In automated feeding systems for shaft-type workpieces (such as shaft blanks), inclined roller conveyor structures are commonly used to achieve directional transport of the shaft blanks. The workpiece rolls forward along the inclined track using its own gravity. Its core components include a guide ramp at a specific angle, limiting side plates, and an end-positioning mechanism. The guide ramp provides a continuous rolling path, the limiting side plates constrain the lateral displacement of the workpiece, and the end-positioning mechanism ensures that the workpiece enters the processing station in a predetermined posture. This design utilizes physical inertia to achieve continuous feeding, featuring simple structure and high transport efficiency. It can maintain a stable motion trajectory and feeding speed in the transport of shaft blanks without surface defects.

[0003] However, when foreign objects such as oil, debris, or machining residue adhere to the arc surface of the shaft blank, these foreign objects create a sudden change in local frictional resistance in the contact area between the shaft blank and the inclined surface. This causes a difference in linear velocity between the two ends of the shaft along its length: the end with greater resistance rolls sluggishly, while the end with less resistance maintains its original speed. This velocity difference triggers axial torque, causing the workpiece to undergo unexpected deflection, which in turn induces jamming or skewness, leading to abnormal material feeding. Summary of the Invention

[0010] In some embodiments, R < A < 3R; where R is the radius of the shaft blank, and A is the dimension of the set size region along the first direction on the side away from the second discharge end when the shaft blank moves from the top surface of the lifting head to the second feed end; the set size region includes the portion in the second direction where the projection areas of the lifting head and the inclined plate do not overlap.

[0011] In some embodiments, the height of the top surface of the inclined plate gradually decreases in the first direction.

[0012] In some embodiments, the working state further includes the process of the lifting head conveying the shaft blank to the second feed end from bottom to top, during which the outer peripheral surface of the shaft blank continuously and simultaneously abuts against the cleaning part and the inclined plate.

[0013] In some embodiments, the second feeding assembly includes a second fixing unit and a second movable unit; the second fixing unit includes a second fixing seat, a second fixing plate, and a second fixing guide rail; the second fixing plate and the second fixing guide rail are respectively connected to the second fixing seat; the second movable unit includes a second movable seat, a second movable plate, and a second movable guide rail; the second movable plate and the second movable guide rail are respectively connected to the second movable seat; the second fixing plate, the second fixing guide rail, the second movable guide rail, and the second movable plate are arranged sequentially along a second direction;

[0014] The designated area also includes the area within the second feeding assembly where the shaft blank abuts against the second fixed guide rail and the second movable guide rail, respectively.

[0015] In some embodiments, the second fixed guide rail and the second movable guide rail are spaced apart along a second direction; the distance between the second fixed guide rail and the second movable guide rail along the second direction is different in at least two places.

[0016] In some embodiments, the second feeding assembly further includes a second driving unit; the second driving unit includes a second slide rail, a second slider, and a second driver; the second slider is connected to the second movable seat; the second slide rail is slidably connected to the second slider; the second driver is drivingly connected to the second slider; the second driver drives the second slider to move the second movable seat toward or away from the second fixed unit.

[0017] In some embodiments, the feeding system further includes a first feeding component; the first inlet end of the first feeding component is higher than the first outlet end of the first feeding component; the first feeding component is disposed on the side of the lifting head away from the second feeding component; the first feeding component is used to store the shaft blank;

[0018] The working state also includes the shaft blank moving sequentially through the first infeed end and the first discharge end to the top surface of the lifting head, and then the lifting head conveys the shaft blank from bottom to top to the second infeed end.

[0019] In some embodiments, the first feeding assembly includes a first fixing unit and a first movable unit; the first fixing unit includes a first fixing seat, a first fixing plate, and a first fixing guide rail; the first fixing plate and the first fixing guide rail are respectively connected to the first fixing seat; the first movable unit includes a first movable seat, a first movable plate, and a first movable guide rail; the first movable plate and the first movable guide rail are respectively connected to the first movable seat; the first fixing plate, the first fixing guide rail, the first movable guide rail, and the first movable plate are arranged sequentially along a second direction; the projection of the cleaning part and the first fixing guide rail in the first direction at least partially overlaps;

[0021] Secondly, this embodiment discloses a feeding method, which is applied to any of the feeding systems described in the first aspect, and the feeding method includes:

[0022] Triggered by the feeding command, the shaft blank is moved to the top surface of the lifting head;

[0023] As the shaft blank moves to the top surface of the lifting head, the lifting head moves upward;

[0024] Based on the lifting head moving up to the second feed end, the lifting head stops moving or moves down.

[0025] To solve the problem of abnormal material feeding caused by foreign matter on the surface of the blank, the present invention has the following advantages:

[0026] The shaft blank is conveyed from bottom to top to the second inlet end of the second feeding assembly via a lifting head. During the conveying process, the shaft blank rotates around its central axis under the combined action of the lifting head and the inclined plate, while the designated area of ​​the shaft blank and the cleaning section maintain relative rolling. This structure allows the shaft blank to rotate continuously during its ascent, forcing the surface of the shaft blank to make rolling friction contact with the cleaning section. Through rolling friction, the cleaning section can effectively remove oil, debris, and other foreign objects adhering to the arc surface of the shaft blank (especially the designated area), thereby eliminating the difference in rolling speed between the two ends of the shaft blank along its length caused by foreign objects. This process ultimately solves the problem of the shaft blank getting stuck and skewed when rolling on the inclined surface of the second feeding assembly due to foreign objects, ensuring that the shaft blank smoothly enters the processing station along the predetermined trajectory and avoiding abnormal interruptions in material supply.

[0036] In the feeding system, when the shaft blank 60 is conveyed by the second feeding assembly 20, since the second inlet end of the second feeding assembly 20 is higher than the second outlet end, an inclined conveying path is formed, and the shaft blank 60 rolls forward along the inclined surface by gravity. However, foreign objects are easily attached to the arc surface of the shaft blank 60. When the shaft blank 60 is in the above-mentioned conveying and rotation process, the foreign objects on the arc surface will disrupt the force balance when the shaft blank 60 rolls at both ends in the length direction, causing the rolling speeds at both ends to be out of sync, which in turn causes the shaft blank 60 to jam and tilt, ultimately resulting in abnormal feeding.

[0037] Example 1:

[0038] This embodiment discloses a feeding system, such as Figure 1 As shown, the feeding system includes a shaft blank 60, a second feeding assembly 20, and a lifting assembly 30.

[0039] The second inlet end of the second feeding assembly 20 is higher than the second outlet end of the second feeding assembly 20. One end of the space enclosed by the second feeding assembly 20 is the second inlet end, and the other end is the second outlet end. The second inlet end is higher than the second outlet end. The second inlet end is higher than the first outlet end. This allows the shaft blank 60 to automatically roll along the second feeding assembly 20 using gravity, achieving continuous conveying of the shaft blank 60. The axial dimension of the shaft blank 60 is smaller than the space enclosed by the second feeding assembly 20 along a second direction (the second direction can be the width direction of the second feeding assembly 20, i.e., ...). Figure 2 The dimensions shown (from bottom to top) allow the shaft blank 60 to be placed within the space enclosed by the second feeding assembly 20.

[0040] The lifting assembly 30 includes a lifting head 32 and a cleaning unit 33. For example... Figure 6 As shown, the decontamination unit 33 includes an inclined plate 331 and a decontamination section 332, which are respectively disposed on the side of the second feeding assembly 20 near the second inlet end. In a first direction, the distance between the side of the inclined plate 331 away from the second outlet end and the second outlet end gradually increases from bottom to top. The first direction is the direction from the second inlet end to the second outlet end (i.e., as shown in the diagram). Figure 2 (As shown from left to right).

[0041] Furthermore, such as Figure 3 As shown, the lifting assembly 30 also includes a third driver 31, which drives the lifting assembly 30 to move.

[0042] The feeding system operates by having the lifting head 32 vertically transport the shaft blank 60 from bottom to top to the second inlet end. The top surface of the lifting head 32, near the inlet end, is higher than or flush with the bottom surface of the second inlet end. Alternatively, the top surface of the lifting head 32, near the second inlet end, is lower than the bottom surface of the second inlet end, and the vertical distance between the top surface of the lifting head 32 near the second inlet end and the bottom surface of the second inlet end is less than 1 / 3 of the radius of the shaft blank 60, thus ensuring that the shaft blank 60 can roll from the lifting head 32 to the second inlet end. During the conveying process, the shaft blank 60 rotates around its central axis under the combined action of the lifting head 32 and the inclined plate 331, and the designated area of ​​the shaft blank 60 rolls relative to the cleaning section 332. The designated area includes the region within the second feeding assembly 20 where the shaft blank 60 abuts against the second feeding assembly 20. An inclined conveying path is constructed by the second feeding assembly 20, the lifting head 32 of the lifting assembly 30 provides conveying power, and the inclined plate 331 provides spatial guidance, so that the shaft blank 60 rotates around the central axis during conveying, and the set area rolls relative to the decontamination part 332, so that the decontamination part 332 cleans the dirt on the surface of the shaft blank 60, and solves the problems of jamming, skewness and abnormal feeding caused by dirt when the shaft blank 60 rolls from the second feeding end to the second discharging end.

[0043] Furthermore, the feeding system also includes a third feeding assembly 40, which includes a base unit 41, a guide unit 42, and a fourth driver 43. One end of the guide unit 42 abuts against the second discharge end. The guide unit 42 is connected to the base unit 41, and the fourth driver 43 is drivenly connected to the guide unit 42, with the drive shaft blank 60 moving on the guide unit 42. The second feeding assembly 20 is connected to the base assembly 50. The lifting assembly 30 is connected to the base assembly 50. The third feeding assembly 40 is connected to the base assembly 50.

[0044] Preferably, R < A < 3R. Wherein, R is the radius of the shaft blank 60, and A is the dimension of the shaft blank 60 along the first direction on the side of the set size region away from the second discharge end when it moves from the top surface of the lifting head 32 to the second inlet end. The set size region includes the portion in the second direction where the projected areas of the lifting head 32 and the inclined plate 331 do not overlap. By limiting this size range, the spatial position of the shaft blank 60 on the lifting head 32 is constrained, allowing the shaft blank 60 to remain stably on the lifting head 32, and accommodating only one shaft blank 60 at a time, avoiding mutual compression of multiple shaft blanks 60 and hindering relative rolling between the shaft blank 60 and the cleaning part 332.

[0045] Preferably, the height of the top surface of the inclined plate 331 gradually decreases in the first direction. By changing the height of the top surface of the inclined plate 331 in the first direction, the positional relationship between the inclined plate 331 and the lifting head 32 is maintained during the conveying of the shaft blank 60, preventing the shaft blank 60 from falling off the lifting head 32, while ensuring that the shaft blank 60 continues to abut against the decontamination unit 33, providing structural support for the decontamination action.

[0046] Furthermore, the working state also includes the process of the lifting head 32 conveying the shaft blank 60 from bottom to top to the second feed end, during which the outer peripheral surface of the shaft blank 60 continuously and simultaneously abuts against the cleaning section 332 and the inclined plate 331. That is, the stroke of the lifting head 32 is the same as the length of the cleaning section 332 and the inclined plate 331. The top ends of the cleaning section 332 and the inclined plate 331 are flush with the second feed end. This ensures that the outer peripheral surface of the shaft blank 60 continuously abuts against the cleaning section 332 and the inclined plate 331 during the process of the lifting head 32 conveying from bottom to top, allowing the cleaning action of the cleaning section 332 on the shaft blank 60 to cover the entire conveying process, thereby improving the stain removal effect.

[0047] Further, the second feeding assembly 20 includes a second fixed unit 21 and a second movable unit 22. The second fixed unit 21 includes a second fixed seat 211, a second fixed plate 212, and a second fixed guide rail 213. The second fixed plate 212 and the second fixed guide rail 213 are respectively connected to the second fixed seat 211, so that the second fixed plate 212 and the second fixed guide rail 213 are firmly installed on the second fixed seat 211. The second movable unit 22 includes a second movable seat 221, a second movable plate 222, and a second movable guide rail 223. The second movable plate 222 and the second movable guide rail 223 are respectively connected to the second movable seat 221. The second fixed plate 212, the second fixed guide rail 213, the second movable guide rail 223, and the second movable plate 222 are arranged sequentially along the second direction to form a channel for the shaft blank 60 to roll. The lateral limiting effect of the second fixed plate 212, the second fixed guide rail 213, the second movable guide rail 223, and the second movable plate 222 guides the shaft blank 60 to roll stably along a predetermined trajectory. The space formed by the second fixed plate 212, the second fixed guide rail 213, the second movable guide rail 223, and the second movable plate 222 has a second inlet end and a second outlet end along its length. The second inlet end can be the end of the top surface of the second fixed guide rail 213 and the second movable guide rail 223 that is close to the inclined plate 331, and the second outlet end can be the end of the top surface of the second fixed guide rail 213 and the second movable guide rail 223 that is away from the inclined plate 331.

[0048] Preferably, the second fixed guide rail 213 and the second movable guide rail 223 are spaced apart along a second direction, providing rolling space for the shaft blank 60 in the second direction. The spacing between the second fixed guide rail 213 and the second movable guide rail 223 along the second direction differs at least in two places. By setting the difference in spacing between the second fixed guide rail 213 and the second movable guide rail 223, the contact position between the shaft blank 60 and the guide rail changes when it rolls, preventing foreign matter remaining on the surface of the shaft blank 60 from repeatedly contacting the guide rail with each roll and reducing the risk of jamming.

[0049] Furthermore, the second feeding assembly 20 also includes a second driving unit. The second driving unit includes a second slide rail, a second slider, and a second driver. The second slider is connected to the second movable seat 221. The second slide rail is slidably connected to the second slider. The second driver is drivingly connected to the second slider. The second driver drives the second slider to move the second movable seat 221 toward or away from the second fixed unit 21. By driving the second slider to move the second movable seat 221, the distance between the second fixed guide rail 213 and the second movable guide rail 223 can be adjusted, thereby making adaptive adjustments according to the length of the shaft blank 60 and improving the adaptability of the second feeding assembly 20 to shaft blanks 60 of different lengths.

[0050] Furthermore, the first feeding assembly 10 also includes a first driving unit 13. For example... Figure 4As shown, the first driving unit 13 includes a first slide rail 131, a first slider 132, and a first driver 133. The first slider 132 is connected to the first movable seat 121. The first slide rail 131 and the first slider 132 are slidably connected. The first driver 133 is driven to the first slider 132. The first driver 133 drives the first slider 132 to move the first movable seat 121 toward or away from the first fixed unit 11. By driving the first slider 132 to move the first movable seat 121 through the first driver 133, the distance between the first fixed guide rail 113 and the first movable guide rail 123 can be adjusted, thereby making adaptive adjustments according to the length of the shaft blank 60 and improving the adaptability of the first feeding assembly 10 to shaft blanks 60 of different lengths.

[0051] Furthermore, such as Figure 5 As shown, the feeding system also includes a first feeding assembly 10, which provides a dedicated storage and conveying structure for the shaft blank 60. The first inlet end of the first feeding assembly 10 is higher than the first outlet end of the first feeding assembly 10. This height setting utilizes gravity to allow the shaft blank 60 to move from the first inlet end to the first outlet end under its own gravity. The first feeding assembly 10 is located on the side of the lifting head 32 away from the second feeding assembly 20. The first feeding assembly 10 is used to store the shaft blank 60.

[0052] The working state also includes the shaft blank 60 moving sequentially through the first inlet end and the first outlet end to the top surface of the lifting head 32, and then the lifting head 32 conveying the shaft blank 60 from bottom to top to the second inlet end. Through the inclined structure and storage function of the first feeding component 10, combined with the movement path design of the shaft blank 60, the continuous supply of the shaft blank 60 is realized, providing a stable material input for the lifting component 30.

[0053] Furthermore, such as Figure 2 As shown, the first feeding assembly 10 includes a first fixed unit 11 and a first movable unit 12. Figure 5 As shown, the first fixing unit 11 includes a first fixing seat 111, a first fixing plate 112, and a first fixing guide rail 113. The first fixing plate 112 and the first fixing guide rail 113 are respectively connected to the first fixing seat 111 and are used to limit and support one side of the shaft blank 60. The first movable unit 12 includes a first movable seat 121, a first movable plate 122, and a first movable guide rail 123. The first movable plate 122 and the first movable guide rail 123 are respectively connected to the first movable seat 121. The first fixing plate 112, the first fixing guide rail 113, the first movable guide rail 123, and the first movable plate 122 are arranged sequentially along the second direction to ensure that the shaft blank 60 will not fall off from the side during the conveying process and to ensure the stability of the conveying path. The decontamination part 332 and the projection of the first fixing guide rail 113 in the first direction at least partially overlap.

[0054] The designated area also includes the area within the first feeding assembly 10 where the shaft blank 60 abuts against the first fixed guide rail 113 and the first movable guide rail 123 respectively, ensuring reliable contact between the shaft blank 60 and the guide rails, and providing structural protection for the stable conveying and initial decontamination of the shaft blank 60.

[0055] Example 2:

[0056] This embodiment discloses a feeding method, which is applied to any of the feeding systems in Embodiment 1. The feeding method includes steps S10 to S30, and each step is described in detail below:

[0057] In step S10, based on the feeding command, the shaft blank 60 is moved to the top surface of the lifting head 32 to ensure that the shaft blank 60 can be moved to the top surface of the lifting head 32 in a timely manner as required, in preparation for subsequent lifting operations.

[0058] In step S20, the shaft blank 60 moves to the top surface of the lifting head 32, and the lifting head 32 moves upward, so that the lifting head 32 can drive the shaft blank 60 to move upward.

[0059] In step S30, based on the lifting head 32 moving upward to the shaft blank 60, the lifting head 32 moves to the second feeding end, and the lifting head 32 stops moving or moves downward to avoid unnecessary pushing or interference to the shaft blank 60 caused by the continuous upward movement of the lifting head 32. At the same time, it makes room for the next lifting operation and ensures that the feeding process is carried out in an orderly cycle.

[0060] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
