Description

TECHNICAL FIELD

[0001] The utility model relates to material classification technical field, and especially relates to a pneumatic turnover type flexible feeder. BACKGROUND

[0002] The traditional vibration feeding system takes the vibration disc as the core and realizes the automatic arrangement and conveying of disordered workpieces through directional vibration. However, the existing spiral track type equipment has obvious limitations: the sorting efficiency is highly dependent on the geometric compatibility of the material and the track cavity, and for special-shaped workpieces, the effective contact surface cannot be formed, which often leads to material turning failure.

[0003] In view of this technical bottleneck, the utility model person puts forward a flexible feeding solution in Chinese patent CN118083523A. The 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 of the flexible material turning area is impacted through the base striking window, so as to promote the separation and turning of the material. However, this design has the problem of motion interference, and the rotating track of the striking hammer interferes with the elastic plate, causing the load fluctuation of the driving motor, affecting the stability and service life of the system. Further, this solution also has the problem of mechanical regulation and control, and reducing the installation height of the striking hammer can alleviate the interference, but it will weaken the effective striking momentum, resulting in insufficient turning kinetic energy.

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

[0024] Figure 6 As shown Figure 5 A cross-sectional schematic diagram. Detailed Implementation

[0025] like Figures 1 to 6As shown, the pneumatic flipping flexible feeder provided in this embodiment includes a base 1, a rotating assembly 2, a flexible disk 3, and a pneumatic striking mechanism 4. The rotating assembly 2 includes a rotating drive 21 and a rotating disk 22. The rotating drive 21 is fixed to the base 1, and the rotating disk 22 is disposed on the base 1 and rotates circumferentially relative to the base 1 following the rotating drive 21. The flexible disk 3 is tensioned and laid on the surface of the rotating disk 22 to rotate with the rotating disk 22. The pneumatic striking mechanism 4 is disposed on the base 1 and located below the flexible disk 3. The pneumatic striking mechanism 4 includes an air supply assembly 41 and at least one pneumatic striking element 42. Driven by the air supply assembly 41, the at least one pneumatic striking element 42 moves in a direction perpendicular to or intersecting the plane of the flexible disk 3 to strike the flexible disk 3.

[0026] This embodiment uses a pneumatic striking mechanism 4, composed of a pneumatic striking component 42 and an air supply assembly 41, to replace the circumferentially rotating striking hammer in the prior art. Compared with the prior art, this effectively reduces the number of complex components such as motors and gear transmissions and lowers frictional losses. Furthermore, the pneumatic striking component 42, moving along a direction perpendicular to or intersecting the plane of the flexible disk 3, has a striking trajectory unaffected 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, making the adjustment of striking force and frequency more precise and controllable, and better adaptable to the needs of different materials. In addition, compared with motor drive, the adjustment of 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 surrounding the base bottom plate 11 and the base panel 12. A rotary drive 21 is fixed to the base panel 12, and a cavity 121 is formed on the base panel 12. At least one pneumatic striking element 42 is disposed within the cavity 121. In the striking state, the pneumatic striking element 42 extends out of the cavity 121 to strike the flexible disk 3. Specifically, the pneumatic striking mechanism 4 also includes a support plate 43 and a protective plate 44. At least one pneumatic striking element 42 is detachably mounted on the support plate 43. The base panel 12 has a mounting hole, and the support plate 43 is fixed to the bottom end of the mounting hole by a locking member. A cavity 121 is formed between the support plate 43 and the peripheral wall of the mounting hole. A 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. The protective plate 44 has a through hole 441 corresponding to at least one pneumatic striking member 42, through which the pneumatic striking member 42 passes to strike the flexible disk 3. However, this invention does not impose any limitations on this. In other embodiments, a cavity may be formed directly in the base panel, with the pneumatic striking member detachably connected to the base panel at the bottom of the cavity; alternatively, a protective plate may not be necessary.

[0028] In the embodiment, the pneumatic striking mechanism 4 comprises a plurality of pneumatic striking members 42, which are distributed on the base 1 in a two-dimensional direction to form a two-dimensional striking area on the flexible disc 3. Specifically, the plurality of pneumatic striking members 42 are installed on the bearing plate 43 in the form of a nearly circular array to form a circular two-dimensional striking area on the flexible disc 3. This arrangement can provide more uniform striking force and a wider striking coverage, thereby more effectively separating and inverting the materials at different positions. However, the present application is not limited thereto. In other embodiments, the plurality of pneumatic striking members can also be distributed on the base in a rectangular or other irregular two-dimensional manner. In the embodiment, as shown in Figure 4 each pneumatic striking member 42 is an independent pneumatic striking member connected with a gas supply assembly 41, and each pneumatic striking member 42 can be controlled independently or synchronously with other pneumatic striking members 42. Alternatively, the plurality of pneumatic striking members 42 are grouped, and the pneumatic striking members 42 in each group strike the flexible disc 3 with corresponding striking conditions (including striking frequency and striking force). For example, the pneumatic striking members 42 in a first group strike the flexible disc 3 with a first striking condition, and the pneumatic striking members 42 in a second group strike the flexible disc 3 with a second striking condition. This arrangement allows different regions in the two-dimensional striking area to have different striking states, thereby achieving accurate striking of specific regions, improving the flexibility of striking and the adaptability to different materials, and being applicable to separation and inversion of materials of different shapes and weights.

[0029] In the embodiment, the pneumatic striking mechanism 4 comprises seven pneumatic striking members 42 and seven gas supply assemblies 41 connected with the seven pneumatic striking members 42, respectively. However, the present application is not limited thereto. In other embodiments, the number of pneumatic striking members can be one or more than two. In addition, in other embodiments, all the pneumatic striking members can be connected with one gas supply assembly, i.e., all the pneumatic striking members have the same striking conditions; or some of the pneumatic striking members share one gas supply assembly.

[0030] As shown in Figure 5 and Figure 6As shown, each pneumatic striking member 42 comprises a gas guide pipe 421, a cylinder 422, a piston rod 423, and a striking part 424 arranged at the end of the piston rod 423. The gas guide pipe 421 is connected to the gas feeding assembly 41, for feeding gas into the cylinder 422 to drive the piston rod 423 to move forward or discharging the gas in the cylinder 422 to reset the piston rod 423. The gas feeding assembly 41 is a gas pump arranged on the base bottom plate 11, and the gas feeding interface of the gas pump is connected to the gas guide pipe 421 through a gas feeding pipe (not shown in the figure) to feed gas into the cylinder 422 or discharge the gas in the cylinder 422. That is, in the embodiment, each striking part 424 is driven by an independent cylinder assembly, and in the control, the gas feeding frequency and strength of the gas feeding assembly (gas pump) can be adjusted to control each striking part 424 individually, so as to realize the individual movement or synchronous movement of each striking part 424 with other striking parts 424. However, the utility model is not limited in this regard. In other embodiments, a plurality of striking parts can be arranged to be connected to a piston rod through a connecting plate, and in this structure, the plurality of striking parts will strike the flexible disc under the same striking condition.

[0031] In the embodiment, as shown in Figure 3 and Figure 4 The rotating disc 22 is a hollow annular structure, and the inner wall thereof is formed with teeth 222. The rotating driving member 21 comprises a rotating driving motor 211 and a driving gear 212 engaged with the teeth 222 of the inner wall of the rotating disc. The rotating driving motor 211 drives the rotating disc 22 to rotate through the driving gear 212. The rotating disc 22 is pressed against the base panel 12 by a pressing ring 23. The outer edge of the rotating disc 22 is formed with a groove 221, and the pressing ring 23 is formed with a protruding part 231 embedded in the groove 221. When the pressing ring 23 is pressed against the rotating disc 22, the protruding part 231 and the groove 221 are matched to rotate with the rotating disc 22. The flexible disc 3 is tightly arranged on the surface of the rotating disc 22. The edge of the flexible disc 3 is tightly pressed against the pressing ring 23 by another pressing ring 24, and the middle part of the flexible disc 3 is connected to the base panel 12 by the limiting shaft 5. The flexible disc 3 rotates with the rotating disc 22 through the two pressing rings 23 and 14, and drives the limiting shaft 5 to rotate relative to the base panel 12.

[0032] In the embodiment, the bottom of the limiting shaft 5 is provided with a detection plate 51 rotating with the flexible disc 3. The pneumatic overturning flexible feeder further comprises a sensor 10 arranged on the bottom of the base panel 12. When the detection plate 51 rotates through the sensor 10, the sensor 10 generates an induction signal to indicate that the flexible disc 3 rotates one round. Specifically, the sensor 10 is an infrared sensor. However, the utility model is not limited in this regard. In other embodiments, the sensor can also be a Hall sensor or other types of sensors.

[0033] In the embodiment, the pneumatic overturning flexible feeder further comprises a pressing member 6 arranged above the flexible disc 3 and at the downstream side edge of the plurality of pneumatic beating members 42, the pressing member 6 presses the flexible disc 3 at the position of the pressing member 6 towards the base 1, so as to block the transmission of the beating force to the flexible disc 3 region at the downstream side of the pneumatic beating member 42. The downstream is defined in the rotation direction of the rotating disc 3, the material overturned by the pneumatic beating member 42 will be transferred to the flexible disc 3 region at the downstream side. The arrangement of the pressing member 6 can ensure that the beating effect is concentrated in the flexible disc 3 region corresponding to the pneumatic beating member 42, so as to avoid that the overturned material is overturned again due to the vibration force. In the embodiment, the pressing member 6 does not fix the flexible disc 3 to the base panel 12, but only applies a vertical downward force to the flexible disc 3 to block the transmission of the beating vibration force; at the same time, the flexible disc 3 still rotates with the rotating disc 22 relative to the base panel 12. Specifically, as shown in Figure 1 and Figure 2 the pressing member 6 comprises two pressing plates, one of which is inclined to extend towards the center of the flexible disc 3, and the other is inclined to extend towards the edge of the flexible disc 3, and the two pressing plates form a discharging channel 60 to guide the orderly discharge of the material, so as to avoid the accumulation of the material at the edge or center of the flexible disc, and improve the smoothness of the feeding. Preferably, both of the two pressing plates 61, 62 are arc-shaped pressing plates. However, the present application does not make any limitation in this regard.

[0034] In order to avoid that the material is separated from the feeder due to excessive beating vibration force during overturning, the embodiment of the pneumatic overturning flexible feeder further comprises a limiting cover 7 arranged above the flexible disc 3 opposite to the pneumatic beating member 42. The limiting cover 7 limits the overturning height during beating, so as to ensure the accurate overturning of the material when falling back under the action of gravity. As shown in Figure 2 the limiting cover 7 is provided with a blocking wall 71 at the side close to the center direction of the flexible disc 3, the blocking wall 71 presses the flexible disc 3 at the position of the blocking wall 71 towards the base, so as to further block the transmission of the beating force to the flexible disc 3 region outside the pneumatic beating member 42.

[0035] In the embodiment, the pneumatic overturning flexible feeder further comprises a vision acquisition assembly 8 arranged above the flexible disc and a light source assembly 9 arranged in the base 1 opposite to the vision acquisition assembly 8. The light source assembly 9 provides light for the vision acquisition device 8 to better capture the material state on the flexible disc 3. The limiting cover 7 is formed with an upstream feeding port 72 and a downstream discharging port 73 distributed on both sides in the rotation direction of the flexible disc 3, and a discharging port 70 at the top of the limiting cover 7. Specifically, during operation, the material is put in from the discharging port 70, separated and overturned by the pneumatic striking part 42, and then output from the downstream discharging port 73 of the limiting cover 7 and rotated to the downstream side. When rotated to the position of the vision acquisition assembly 8, the vision acquisition assembly 8 acquires the material state on the flexible disc 3 to form an acquisition image, analyzes the acquisition image to obtain the material coordinate information of the overturning state meeting the requirements, and transmits the material coordinate information of the overturning state meeting the requirements to the mechanical arm to make the mechanical arm grasp the corresponding material. The material whose overturning state does not meet the requirements is re-entered into the position of the pneumatic striking part 42 through the upstream feeding port 72 for overturning; at the same time, new materials are continuously put in from the discharging port 70. However, the specific operation process of the pneumatic overturning flexible feeder is not limited in the utility model.

[0036] In summary, the pneumatic overturning flexible feeder provided by the utility model adopts pneumatic striking parts to vertically or obliquely strike the flexible disc, and the pneumatic striking does not need to rotate and rub, thereby reducing the part wear and prolonging the service life of the equipment. The vertical or intersecting driving based on air pressure can realize accurate adjustment of the striking force and frequency, is suitable for different material characteristics, and has good versatility. At the same time, the adjustment of the striking force based on air pressure is very simple and does not need the interference of other parts. Further, the setting of the pneumatic striking mechanism eliminates the complex rotary driving mechanism (such as a motor and a gear), thereby reducing the manufacturing cost and the maintenance difficulty.

[0037] In addition, a plurality of pneumatic striking parts are distributed in the base in an array form to realize two-dimensional direction striking. The setting expands the striking action range, strikes more areas of the flexible disc, and thus solves the problem of limited striking range caused by single striking in the prior art. At the same time, the array striking can also disperse the impact force, avoid local overload, and improve the uniformity of material separation. The setting of the plurality of pneumatic striking parts also makes it possible to selectively activate different pneumatic striking parts during work, flexibly cope with the complex distribution of special-shaped materials, and has the advantage of strong material adaptability.

[0038] Although the utility model has been disclosed as above by the preferred embodiment, it is not used to limit the utility model, and any person skilled in the art can make some changes and decorations without departing from the spirit and scope of the utility model, so the protection scope of the utility model shall be subject to the scope required by the claims.
