Description

Technical Field

[0001] The invention relates to the technical field of material classification, and in particular to a pneumatic flip-type flexible feeder. Background Art

[0002] The traditional vibrating feeding system is based on the vibrating plate, which realizes the automatic arrangement and conveying of disordered workpieces through directional vibration. However, the existing spiral track equipment has obvious limitations: its sorting efficiency is highly dependent on the geometric adaptability of the material and the track cavity. For special-shaped workpieces, it cannot form an effective contact surface, which often leads to failure of turning the material.

[0003] In response to this technical bottleneck, the inventor proposed a flexible feeding solution in Chinese patent CN118083523A. Its innovation lies in the use of a striking hammer assembly: the striking hammer is driven by a motor to rotate 360 ​​degrees, and the elastic plate in the flexible material turning area is impacted through the base striking window, thereby causing the material to separate and flip. However, this design has a motion interference problem. The rotating trajectory of the striking hammer and the elastic plate produce dynamic interference, resulting in load fluctuations of the drive motor, affecting the stability and service life of the system. Furthermore, this solution also has a mechanical control dilemma. Although lowering the installation height of the striking hammer can alleviate interference, it will weaken the effective striking momentum, resulting in insufficient flipping kinetic energy.

[0004] In addition, the above scheme also has the problem of a narrow striking range. Specifically, due to the characteristics of circular motion, even if a multi-hammer structure is used, the effective striking point is still limited to the tangent position at the top of the flexible material turning area, that is, only point striking can be achieved and it is difficult to form a surface impact effect. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a pneumatic flip-type flexible feeder.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a pneumatic flip-type flexible feeder, which includes a base, a rotating assembly, a flexible disk and a pneumatic striking mechanism. The rotating assembly includes a rotating drive member and a rotating disk, the rotating drive member is fixed to the base, and the rotating disk is arranged on the base and follows the rotating drive member to rotate circumferentially relative to the base. The flexible disk is stretched and laid on the surface of the rotating disk to rotate with the rotating disk. The pneumatic striking mechanism is arranged on the base and is located below the flexible disk. The pneumatic striking mechanism includes an air delivery assembly and at least one pneumatic striking member. The at least one pneumatic striking member moves in a direction perpendicular to or intersecting with the plane where the flexible disk is located under the drive of the air delivery assembly to strike the flexible disk.

[0007] According to an embodiment of the present invention, the pneumatic striking mechanism includes a plurality of pneumatic striking members, and the plurality of pneumatic striking members are distributed on the base in a two-dimensional direction to form a two-dimensional striking area on the flexible disk.

[0008] According to one embodiment of the present invention, there is at least one independent pneumatic striking member among the plurality of pneumatic striking members, the independent pneumatic striking member is independently connected to an air delivery assembly, and the independent pneumatic striking member strikes the flexible disk independently or strikes the flexible disk together with other pneumatic striking members.

[0009] According to one embodiment of the present invention, the pneumatic flip-type flexible feeder also includes a clamping member arranged above the flexible disk and located at the downstream edge of at least one pneumatic striking member. The clamping member presses the flexible disk where it is located toward the base, thereby blocking the striking force from being transmitted to the flexible disk area on the downstream side of the pneumatic striking member.

[0010] According to an embodiment of the present invention, the pressing member includes two pressing plates, one of which extends obliquely toward the center of the flexible disk, and the other extends obliquely toward the edge of the flexible disk, and a discharge channel is formed between the two pressing plates.

[0011] According to one embodiment of the present invention, the pneumatic flipping flexible feeder also includes a limit cover arranged above the flexible disk opposite to at least one pneumatic striking member, the limit cover limits the flipping height, and the limit cover is provided with an upstream feed port and a downstream discharge port distributed on both sides along the rotation direction of the flexible disk, as well as a drop port located at the top of the limit cover.

[0012] According to an embodiment of the present invention, a blocking wall is formed on one side of the limiting cover close to the center direction of the flexible disk, and the blocking wall presses the flexible disk where the blocking wall is located toward the base.

[0013] According to one embodiment of the present invention, the base includes a base bottom plate and a base panel, the rotating driving member is fixed to the base panel, a concave cavity is formed on the base panel, and at least one pneumatic striking member is arranged in the concave cavity; in the striking state, the pneumatic striking member extends out of the concave cavity to strike the flexible disk.

[0014] According to an embodiment of the present invention, the pneumatic flip-type flexible feeder further includes a vision collection component disposed above the flexible disk and a light source component disposed in the base opposite to the vision collection component.

[0015] According to one embodiment of the present invention, each pneumatic striking member includes an air duct, a cylinder, a piston rod and a striking part arranged at the end of the piston rod. The air duct is connected to the air supply assembly, which is used to supply air into the cylinder to drive the piston rod forward or to discharge the gas in the cylinder to reset the piston rod.

[0016] In summary, the pneumatic flip-type flexible feeder provided by the present invention adopts a pneumatic striking member to vertically or obliquely strike the flexible disk. The pneumatic striking does not require rotational friction, which reduces component wear and extends the life of the equipment. The vertical or intersecting drive based on air pressure can achieve precise adjustment of the striking force and frequency, adapt to different material characteristics and have good versatility; at the same time, the striking force adjustment based on air pressure is also very simple and does not require interference from other components. Furthermore, the setting of the pneumatic striking mechanism eliminates the need for complex rotary drive mechanisms (such as motors and gears), reducing manufacturing costs and maintenance difficulties.

[0017] In addition, multiple pneumatic striking pieces are distributed in an array on the base to achieve two-dimensional striking. This setting expands the striking range and covers more areas of the flexible disk, thereby solving the problem of limited striking range due to single-point striking in the prior art; at the same time, array striking can also disperse the impact force, avoid local overload, and improve the uniformity of material separation; and the setting of multiple pneumatic striking pieces also enables the selective activation of different pneumatic striking pieces during work, and flexibly responds to the complex distribution of special-shaped materials, which has the advantage of strong material adaptability.

[0018] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, preferred embodiments are given below and described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figures 1 to 6As shown, the pneumatic flip-type flexible feeder provided in this embodiment includes a base 1, a rotating component 2, a flexible disk 3 and a pneumatic striking mechanism 4. The rotating component 2 includes a rotating drive member 21 and a rotating disk 22, the rotating drive member 21 is fixed to the base 1, and the rotating disk 22 is arranged on the base 1 and follows the rotating drive member 21 to rotate relative to the base 1 in a circumferential direction. The flexible disk 3 is stretched and laid on the surface of the rotating disk 22 to rotate with the rotating disk 22. The pneumatic striking mechanism 4 is arranged on the base 1 and is located below the flexible disk 3. The pneumatic striking mechanism 4 includes an air delivery component 41 and at least one pneumatic striking member 42. The at least one pneumatic striking member 42 moves in a direction perpendicular to or intersecting with the plane where the flexible disk 3 is located under the drive of the air delivery component 41 to strike the flexible disk 3.

[0026] This embodiment adopts a pneumatic striking mechanism 4 composed of a pneumatic striking member 42 and an air delivery component 41 to replace the striking hammer rotating in the circumferential direction in the prior art. Compared with the prior art, the number of complex components such as motors and gear transmissions can be effectively reduced and friction losses can be reduced. Furthermore, the pneumatic striking member 42 that moves in a direction perpendicular to or intersecting the plane where the flexible disk 3 is located has a moving striking trajectory that is not interfered with by other components and does not affect the striking force. The adjustment of the striking force is only related to the pneumatic striking mechanism 4 itself, and the adjustment of the striking force and frequency is more accurate and controllable, and can be well adapted to the needs of different materials. In addition, compared with motor drive, the adjustment of the striking pressure based on the pneumatic striking mechanism 4 will also have a faster response speed.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, the base 1 includes a base bottom plate 11, a base panel 12, and a base enclosure 13 arranged around the base bottom plate 11 and the base panel 12. The rotary drive member 21 is fixed to the base panel 12, and a concave cavity 121 is formed on the base panel 12. At least one pneumatic striking member 42 is arranged in the concave cavity 121. In the striking state, the pneumatic striking member 42 extends out of the concave cavity 121 to strike the flexible disk 3. Specifically, the pneumatic striking mechanism 4 also includes a bearing plate 43 and a protective plate 44. At least one pneumatic striking member 42 is detachably mounted on the bearing plate 43. The base panel 12 has a mounting hole. The bearing plate 43 is fixed to the bottom end of the mounting hole through a locking member. A concave cavity 121 is formed between the bearing plate 43 and the peripheral wall of the mounting hole. The protective plate 44 is disposed at the top of the mounting hole to prevent debris from falling into the pneumatic striking member 42 and affecting its striking motion. A through hole 441 corresponding to at least one pneumatic striking member 42 is formed on the protective plate 44. The pneumatic striking member 42 penetrates the through hole 441 to strike the flexible disk 3. However, the present invention is not limited to this. In other embodiments, a concave cavity may be directly formed on the base panel, and the pneumatic striking member may be detachably connected to the base panel at the bottom of the concave cavity; in addition, the protective plate may not be required.

[0028] In this embodiment, the pneumatic striking mechanism 4 includes a plurality of pneumatic striking members 42, and the plurality of pneumatic striking members 42 are distributed on the base 1 in a two-dimensional direction, forming a two-dimensional striking area on the flexible disk 3. Specifically, the plurality of pneumatic striking members 42 are installed on the supporting plate 43 in a nearly circular array, forming a circular two-dimensional striking area on the flexible disk 3. This arrangement can provide a more uniform striking force and a wider striking coverage, thereby more effectively separating and flipping materials at different positions. However, the present invention is not limited to this. In other embodiments, the plurality of pneumatic striking members may also be distributed on the base in a rectangular or other irregular two-dimensional manner. In this embodiment, if Figure 4 As shown, each pneumatic striking member 42 is an independent pneumatic striking member connected to a gas delivery assembly 41, and each pneumatic striking member 42 can be controlled individually or synchronously with other pneumatic striking members 42. Alternatively, multiple pneumatic striking members 42 are grouped, and the pneumatic striking members 42 in each group strike the flexible disk 3 with corresponding striking conditions (including striking frequency and striking force); for example, the pneumatic striking members 42 in the first group strike the flexible disk 3 with the first striking condition, and the pneumatic striking members 42 in the second group strike the flexible disk 3 with the second striking condition. This setting allows different areas in the two-dimensional striking area to have different striking states, thereby achieving precise striking in specific areas, improving the flexibility of striking and adaptability to different materials, and can be applied to the separation and flipping of materials of different shapes and weights.

[0029] In this embodiment, the pneumatic striking mechanism 4 includes seven pneumatic striking members 42 and air supply components 41 respectively connected to the seven pneumatic striking members 42. However, the present invention does not impose any limitation on this. In other embodiments, the pneumatic striking member may also be one or more other values. In addition, in other embodiments, all pneumatic striking members may be connected to a common air supply component, that is, all pneumatic striking members have the same striking conditions; or, some pneumatic striking members may share a common air supply component.

[0030] like Figure 5 and Figure 6As shown, each pneumatic striking member 42 includes an air pipe 421, a cylinder 422, a piston rod 423, and a striking portion 424 disposed at the end of the piston rod 423. The air pipe 421 is connected to the air delivery assembly 41, and is used to deliver air into the cylinder 422 to drive the piston rod 423 forward or to discharge the gas in the cylinder 422 to reset the piston rod 423. The air delivery assembly 41 is an air pump disposed on the base bottom plate 11, and the air delivery interface of the air pump is connected to the air pipe 421 through an air delivery pipe (not shown in the figure), and air is delivered into the cylinder 422 or the gas in the cylinder 422 is discharged through the air pipe 421. That is, in this embodiment, each striking portion 424 is driven individually by an independent cylinder assembly, and each striking portion 424 can be individually controlled by adjusting the air delivery frequency and strength of the air delivery assembly (air pump) during control, thereby realizing the individual movement of each striking portion 424 or synchronous movement with other striking portions 424. However, the present invention does not make any limitation to this. In other embodiments, multiple striking parts may be provided to be connected to a piston rod through a connecting plate. In this structure, the multiple striking parts will strike the flexible disk under the same striking conditions.

[0031] In this embodiment, if Figure 3 and Figure 4 As shown, the rotating disk 22 is a hollow annular structure and its inner wall is formed with teeth 222. The rotating drive member 21 includes a rotating drive motor 211 and a driving gear 212 meshed with the teeth 222 on the inner wall of the rotating disk. The rotating drive motor 211 drives the rotating disk 22 to rotate through the driving gear 212. The rotating disk 22 is pressed toward the base panel 12 through a pressing ring 23. A groove 221 is formed at the outer edge of the rotating disk 22. A protrusion 231 embedded in the groove 221 is formed on the pressing ring 23. The pressing ring 23 follows the rotating disk 22 to rotate while pressing the rotating disk 22 through the cooperation of the protrusion 231 and the groove 221. The flexible disk 3 is laid on the surface of the rotating disk 22 under tension. The edge of the flexible disk 3 is pressed against the pressing ring 23 through another pressing ring 24. The middle part of the flexible disk 3 is connected to the base panel 12 through the limiting shaft 5. The flexible disk 3 rotates with the rotating disk 22 through two pressure rings 23 and 14 and drives the limiting shaft 5 to rotate relative to the base panel 12 .

[0032] In this embodiment, a detection plate 51 is disposed at the bottom of the limit shaft 5 and rotates with the flexible disk 3. The pneumatic flip-type flexible feeder further includes a sensor 10 disposed at the bottom of the base panel 12. When the detection plate 51 rotates past the sensor 10, the sensor 10 generates a sensing signal to indicate that the flexible disk 3 rotates one circle. Specifically, the sensor 10 is an infrared sensor. However, the present invention does not make any limitation to this. In other implementations, the sensor may also be a Hall sensor or other types of sensors.

[0033] In the present embodiment, the pneumatic flipping flexible feeder also includes a clamping member 6 disposed above the flexible disk 3 and located at the downstream edge of the plurality of pneumatic striking members 42. The clamping member 6 presses the flexible disk 3 where it is located toward the base 1, thereby blocking the transmission of the striking force to the flexible disk 3 area downstream of the pneumatic striking member 42. The downstream is defined by the rotation direction of the rotating disk 3, and the material that has been vibrated and flipped by the pneumatic striking member 42 will be transferred to the flexible disk 3 area downstream thereof. The provision of the clamping member 6 can ensure that the striking effect is concentrated on the area of ​​the flexible disk 3 corresponding to the pneumatic striking member 42, thereby preventing the material that has been flipped from flipping again due to the vibration force. In the present embodiment, the clamping member 6 does not fix the flexible disk 3 to the base panel 12, but only applies a vertical downward force to the flexible disk 3 to block the transmission of the striking vibration force; at the same time, the flexible disk 3 still rotates relative to the base panel 12 following the rotating disk 22. Specifically, as Figure 1 and Figure 2 As shown, the pressing member 6 includes two pressing plates, one of which 61 extends obliquely toward the center of the flexible disk 3, and the other 62 extends obliquely toward the edge of the flexible disk 3. A discharge channel 60 is formed between the two pressing plates to guide the orderly discharge of materials, avoid the accumulation of materials at the edge or center of the flexible disk, and improve the smoothness of feeding. Preferably, the two pressing plates 61 and 62 are both arc-shaped pressing plates. However, the present invention does not make any limitation to this.

[0034] In order to prevent the material from being separated from the feeder due to excessive vibration during the material turning, the pneumatic turning flexible feeder in this embodiment also includes a limit cover 7 arranged above the flexible plate 3 opposite to the pneumatic striking member 42. The limit cover 7 limits the turning height during the striking, ensuring the accurate turning of the material when it falls back under gravity. Figure 2 As shown, a blocking wall 71 is formed on one side of the limiting cover 7 close to the center direction of the flexible disk 3. The blocking wall 71 presses the flexible disk 3 where it is located toward the base to further block the striking force from being transmitted to the area of ​​the flexible disk 3 outside the pneumatic striking member 42.

[0035] In this embodiment, the pneumatic flip-type flexible feeder also includes a visual acquisition component 8 disposed above the flexible disk and a light source component 9 disposed in the base 1 opposite to the visual acquisition component 8. The light source component 9 provides light for the visual acquisition device 8 so that it can better capture the material state on the flexible disk 3. The limiting cover 7 is formed with an upstream feed port 72 and a downstream discharge port 73 distributed on both sides along the rotation direction of the flexible disk 3, and a drop port 70 located at the top of the limiting cover 7. Specifically, during operation, the material is put into the drop port 70, and the material is separated and flipped by the pneumatic striking member 42, and then output from the downstream discharge port 73 of the limiting cover 7 and rotated to the downstream side. When rotating to the location of the visual acquisition component 8, the visual acquisition component 8 obtains the material state on the flexible disk 3 to form a collection image, analyzes the collection image to obtain the material coordinate information whose flipping state meets the requirements, and transmits the material coordinate information whose flipping state meets the requirements to the robot arm so that the robot arm can grab the corresponding material. The material that does not meet the requirements of the flipping state enters the pneumatic striking member 42 again through the upstream feed port 72 for flipping; at the same time, new materials are continuously put in from the drop port 70. However, the present invention does not limit the specific operation process of the pneumatic flipping flexible feeder.

[0036] In summary, the pneumatic flip-type flexible feeder provided by the present invention adopts a pneumatic striking member to vertically or obliquely strike the flexible disk. The pneumatic striking does not require rotational friction, which reduces component wear and extends the life of the equipment. The vertical or intersecting drive based on air pressure can achieve precise adjustment of the striking force and frequency, adapt to different material characteristics and have good versatility; at the same time, the striking force adjustment based on air pressure is also very simple and does not require interference from other components. Furthermore, the setting of the pneumatic striking mechanism eliminates the need for complex rotary drive mechanisms (such as motors and gears), reducing manufacturing costs and maintenance difficulties.

[0037] In addition, multiple pneumatic striking pieces are distributed in an array on the base to achieve two-dimensional striking. This setting expands the striking range and covers more areas of the flexible disk, thereby solving the problem of limited striking range due to single-point striking in the prior art; at the same time, array striking can also disperse the impact force, avoid local overload, and improve the uniformity of material separation; and the setting of multiple pneumatic striking pieces also enables the selective activation of different pneumatic striking pieces during work, and flexibly responds to the complex distribution of special-shaped materials, which has the advantage of strong material adaptability.

[0038] Although the present invention has been disclosed as above by the preferred embodiment, it is not intended to limit the present invention. Anyone familiar with this technology can make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection required by the claims.
