Technical Field

[0001] The present invention relates to the technical field of material sorting, and particularly to a device for feeding conical objects into a conduit for sorting. Background Art

[0002] In the injection molding industry, after the liquid plastic solidifies in the mold, the conical plastic workpieces fall into the turnover box at the bottom of the injection molding machine disorderly. The conical plastic workpieces in the turnover box are in a chaotic state. When transporting the conical objects to the next process, it is necessary to ensure that the conical workpieces are neatly distributed and they need to be sorted.

[0003] The diameter of the top of the conical part is smaller than that of the bottom end of the cone. When the conical part enters the gradually shrinking guide groove from a container with a planar area several times larger than that of the cone, when the cross-sectional width dimension of the guide groove is equal to the repose dimension, the conical object will get stuck in the area of the repose dimension and cannot continue to advance into the guide groove, resulting in the problem of material jamming. Therefore, the present application proposes a device for feeding conical objects into a conduit for sorting. Summary of the Invention

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0052] Embodiment 1

[0053] As Figures 1 to 4As shown in the figure, an apparatus for feeding conical objects into a conduit for sorting according to an embodiment of the present invention includes a conical chute 10, a first conduit 20, a swinging mechanism 30, and a nozzle assembly 40. The conical chute 10 is a trough that tapers longitudinally into a cone shape. A front cover plate 15 and a rear cover plate 16 are respectively provided at the small end and the large end of the conical chute 10. A closed structure near the small end and an open structure near the large end are provided at the top of the conical chute 10. The first conduit 20 is fixedly connected to the front cover plate 15 and is in communication with the conical chute 10. The lowest point of the edge of the end of the first conduit 20 connected to the conical chute 10 is not higher than the bottom of the inner wall of the conical chute 10. The inner diameter of the first conduit 20 is between 1 time and 2 times the rest dimension of the conical object. The swinging mechanism 30 includes a swinging shaft 31 and a swinging motor 32. The swinging shaft 31 is rotatably connected inside the conical chute 10. The swinging motor 32 is used to drive the swinging shaft 31 to swing. The nozzle assembly 40 is fixedly connected to the swinging shaft 31 in a suspended manner through a cantilever 41, and the nozzle assembly 40 blows out an air flow directed at the first conduit 20 after the air source is connected.

[0054] In this embodiment, when sorting conical objects, the conical objects are poured into the conical chute 10. The conical objects are disorderly distributed in the conical chute 10. The nozzle assembly 40 is connected to the air source, the swinging motor 32 and the air source are started. The nozzle assembly 40 blows out an air flow. The swinging motor 32 drives the nozzle assembly 40 to swing in the conical chute 10 through the swinging shaft 31 and the cantilever 41. The air flow blown out by the nozzle assembly 40 forms a vortex in the closed part of the conical chute 10, stirring the conical objects located in the conical chute 10. At the same time, the air flow forms a positive pressure in the conical chute 10, driving the conical objects located at the mouth of the first conduit 20 into the first conduit 20. Since the inner diameter of the first conduit 20 is greater than 1 time the rest dimension of the conical object and less than 2 times the rest dimension of the conical object, two conical objects cannot enter the first conduit 20 at the same time. Therefore, under the action of the air flow, the conical objects in the conical chute 10 enter the first conduit 20 in sequence and are sorted in the first conduit 20. Due to the flow of the gas, the conical objects are also pushed by the air flow to move in the first conduit 20. The swinging of the nozzle assembly 40 can make the air flow stir the conical objects located in the conical chute 10, preventing multiple conical objects from blocking the mouth of the first conduit 20.

[0055] The device for feeding conical objects into a conduit for sorting disclosed in the embodiments of the present invention solves the problem of material jamming by setting the conical chute 10 to be longitudinally tapered into a conical structure and setting its top opening to be a semi-closed opening. When sorting conical objects, a swinging air flow generated by the air nozzle assembly 40 located in the conical chute 10 agitates the conical objects and forms a positive pressure at the closed end of the conical chute 10, blowing the conical objects located in the conical chute 10 into the first conduit 20 in sequence. Compared with the prior art, the present invention can greatly reduce the occurrence frequency of material jamming problems during the feeding process of conical objects.

[0056] Specifically, in this embodiment, as Figure 3 shown, the conical chute 10 is a rhombic chute, and the conical chute 10 is composed of a first inclined plate 11 and a second inclined plate 12 that are three-dimensionally inclined, and front cover plates 15 and rear cover plates 16 located at both ends of the first inclined plate 11 and the second inclined plate 12. The sides of the first inclined plate 11 and the second inclined plate 12 are connected to form a horizontally placed V-shaped structure. Two first inclined plates 11 and two second inclined plates 12 are provided, and the two first inclined plates 11 and the two second inclined plates 12 are mirror-symmetrically arranged to form a conical trough structure. The angles between the first inclined plate 11 and the second inclined plate 12 and the horizontal plane are both greater than the angle of repose of the conical object. The two mirror-symmetrically arranged first inclined plates 11 form a trough structure with a V-shaped opening facing upward. The top cover plate of the conical chute 10 includes a first cover plate 13 and a second cover plate 14. The first cover plate 13 and the second cover plate 14 are both inclined. The first cover plate 13 and the second cover plate 14 are longitudinally distributed on the second inclined plate 12. The first cover plate 13 forms a closed structure of a semi-closed opening. The first cover plate 13 and the second cover plate 14 are coplanar. The second cover plate 14 forms the mouth structure of the semi-closed opening.

[0057] For any solid object on an inclined plane, there are different angles of repose according to the shape of the object and the potential of the center of gravity. For example, for a spherical object, because its shape is spherical and it contacts the plane at a point, when the plane angle is slightly greater than 0° horizontal, the circular object will roll on the plane, and the angle formed by the plane and the horizontal plane is the angle of repose. Another example is a rectangular cube. Because its shape is rectangular and it contacts the plane with one of its planes, the kinetic energy required for it to slide on the plane is greater than the frictional force between the rectangular object and the plane before it can slide on the plane. When the plane forms an angle greater than 0° with the horizontal plane and the kinetic energy formed by the potential of the rectangular object is greater than the frictional force between the rectangular object and the plane, the rectangular object will slide on the plane, and this angle greater than 0° is the angle of repose.

[0058] The rest dimension is the distance between two structures that just hold the conical object, or it can also be the distance between the two farthest points on the surface of the conical object. When the distance between the two structures is greater than the rest dimension of the conical object, the conical object will not be held by these two structures.

[0059] Preferably, the groove-like structure formed by the two first inclined plates 11 is arranged at an inclination of 0.5° to 30°, that is, the small end of the conical chute 10 is arranged downward. The included angle between the first inclined plate 11 and the second inclined plate 12 is 70° to 110°, and the included angle between the front cover plate 15 and the first inclined plate 11 is 80° to 105°.

[0060] As a preferred implementation manner in this embodiment, the first inclined plate 11, the second inclined plate 12, and the first cover plate 13 are of an integral structure. The first inclined plate 11, the second inclined plate 12, and the first cover plate 13 form half of the conical chute 10 through cutting and bending. The structure formed by the first inclined plate 11, the second inclined plate 12, and the first cover plate 13 is combined by folding. The front cover plate 15 and the rear cover plate 16 are fixedly connected to the first inclined plate 11, the second inclined plate 12, the first cover plate 13, or the second cover plate 14 by welding.

[0061] It should be noted that in other implementation manners of the conical chute 10, the conical chute 10 can also be a conical structure or a structure composed of a semi-cone and a V-shaped groove. The processing method of the conical chute 10 in this embodiment is simpler. Therefore, it is preferably a diamond groove structure.

[0062] As another implementation manner in this embodiment, as Figure 8 shown, the conical chute 10 further includes a straight side plate 17. The straight side plate 17 is fixedly connected to the first inclined plate 11. The straight side plate 17 and the second inclined plate 12 form the side plate structure of the conical chute 10. The straight side plate 17 is located on the side close to the rear cover plate 16. The second cover plate 14 is located on the side of the straight side plate 17 away from the first inclined plate 11, that is, the second cover plate 14 is a bent structure of the upper edge of the straight side plate 17. After the conical chute 10 is installed, the straight side plate 17 is vertically arranged. The straight side plate 17, the rear cover plate 16, and the first cover plate 13 enclose the mouth structure of the conical chute 10.

[0063] The first conduit 20 is a straight pipe or a bent pipe. The end of the first conduit 20 is fixedly connected to the front cover plate 15 by means of a pipe interface or welding. In this embodiment, for example, a pipe interface is provided on the front cover plate 15, and the first conduit 20 is fixed to the pipe interface by a clamp.

[0064] The first conduit 20 may also be a square pipe. The specific structure of the first conduit 20 is selected by the designer according to the specific product. It should be noted that the size of the first conduit 20 needs to be larger than the diameter of the large end of the conical object and smaller than the angle of repose size of the conical object.

[0065] As Figure 1 and Figure 3 shown, the swing motor 32 drives the swing shaft 31 to swing through the connecting rod 33. The swing shaft 31 is rotatably connected to the rear cover plate 16 through a bearing and a flange bearing seat. The bearing seat is fixedly connected to the rear cover plate 16 and the support structure inside the chute by bolts. The bearing is sleeved on the swing shaft 31 and is fixedly attached to the bearing seat by interference fit. A rocker structure is fixed to one end of the swing shaft 31 outside the conical chute 10 and close to the rear cover plate 16. A crank structure is fixed to the output shaft of the swing motor 32. The two ends of the connecting rod 33 are respectively hinged to the crank structure and the rocker structure. The swing shaft 31, swing motor 32, connecting rod 33, crank structure, and rocker structure form a crank-rocker mechanism, and the swing motor 32 serves as the power output end;

[0066] In this embodiment, the conical chute 10 and the swing mechanism 30 are installed on the support 50. The support 50 is a frame structure. The conical chute 10 and the swing mechanism 30 are fixedly connected to the support 50 by bolts.

[0067] Preferably, as Figure 7 shown, a protective cover 34 is further provided outside the swing mechanism 30. The protective cover 34 is a square shell structure. The protective cover 34 covers the swing mechanism 30, and the protective cover 34 is fixedly connected to the swing mechanism 30 by bolts.

[0068] As Figure 4 and Figure 5 shown, the cantilever 41 includes a first support on the swing shaft 31 and a second support on the air nozzle assembly 40. The first support includes a fixed sleeve and a connecting strip. The fixed sleeve is a cylindrical shape with openings at both ends. The fixed sleeve is fixed to the swing shaft 31 by screws. The connecting strip and the fixed sleeve are an integral structure. The connecting strip is perpendicular to the axis of the fixed sleeve. The second support is a strip structure. One end of the second support is connected to the connecting strip by bolts, and the other end is sleeved on the air nozzle assembly 40 by interference fit.

[0069] The air nozzle assembly 40 is an air nozzle structure connecting to the air source in the prior art. For example, the air nozzle assembly 40 is a round tube type air nozzle structure.

[0070] As a preferred implementation manner in this embodiment, the included angle between the air nozzle assembly 40 and the bottom of the conical chute 10 is about -5° to 5°, and the air pressure in the air nozzle assembly 40 is about 0.4 to 0.7 MPa.

[0071] As a preferred implementation manner in this embodiment, as Figures 3 to 6 shown, a grid curtain 18 is further arranged in the conical chute 10. The grid curtain 18 is composed of a plurality of grid curtain rods 181. The grid curtain 18 is fixedly connected to the inside of the conical chute 10 through a curtain frame 19. The grid curtain 18 is located between the air nozzle assembly 40 and the front cover plate 15. The curtain frame 19 is an L-shaped plate. A plurality of grid curtain rods 181 are fixedly connected to the curtain frame 19 through bolts. The curtain frame 19 is fixedly connected to the rear cover plate 16 through a connecting plate 191. The connecting plate 191 is U-shaped. A plurality of the connecting plates 191 are sequentially connected through bolts. The connecting plate 191 close to the rear cover plate 16 is fixedly connected to the rear cover plate 16 through bolts. The connecting plate 191 is used to avoid the swing shaft 31. The grid curtain 18 is used to block the conical object from being blown to the large end of the conical chute 10, that is, the position of the rear cover plate 16 facing the small end.

[0072] As a preferred implementation manner in this embodiment, in the case where the grid curtain 18 is not provided, a fixed nozzle is arranged on the rear cover plate 16. The fixed nozzle continuously sprays air flow to prevent the conical object from entering the rear of the air nozzle assembly 40. The distance between the fixed nozzle and the bottom of the conical chute 10 is 15 - 25 mm.

[0073] Embodiment 2

[0074] As Figures 9 to 12 shown, as another embodiment of the present invention, the difference between this embodiment and Embodiment 1 is that the device further includes:

[0075] A sorting mechanism 60, which is fixedly connected to the discharge port of the first conduit 20 and is used to control the conical objects to be discharged one by one to prevent the conical objects from being nested;

[0076] A gate mechanism 70, which is fixedly connected to the discharge port of the sorting mechanism 60 and is used to temporarily block the discharge of the conical objects to cooperate with the sorting mechanism 60 to work.

[0077] Specifically, as Figure 9 、 Figure 10 and Figure 11 shown, in this embodiment, the sorting mechanism 60 includes:

[0078] Sorting bin 61, a first channel penetrating the sorting bin 61 is arranged inside the sorting bin 61, one end of the first channel is communicated with one end of the first conduit 20 away from the conical chute 10, and the gate mechanism 70 is used for intermittently closing one end of the first channel away from the first conduit 20;

[0079] First jaw assembly 62, the first jaw assembly 62 is located at one end of the first channel close to the first conduit 20 and is used for grasping overlapping conical objects;

[0080] Second jaw assembly 63, the second jaw assembly 63 is located inside the first channel and is used for grasping the conical object on the gate mechanism 70. The distance between the second jaw assembly 63 and the first jaw assembly 62 is greater than the height of one conical object and less than the height of two conical objects;

[0081] Lifting module 64, the first jaw assembly 62 is fixedly connected to the output end of the lifting module 64, and the lifting module 64 is used for lifting the second jaw assembly 63 to separate adjacent conical objects;

[0082] Induction module 65, which is used to identify the conical object entering the first channel to form a control signal.

[0083] As Figures 10 to 12 shown, in this embodiment, the sorting bin 61 is a square shell composed of square structures, the first channel is composed of the square structures constituting the sorting bin 61, the sorting bin 61 is fixedly connected to one end of the first conduit 20 away from the conical chute 10 through bolts, the structures of the first jaw assembly 62 and the second jaw assembly 63 are the same, and both are jaw cylinders. The first jaw assembly 62 and the second jaw assembly 63 are controlled by a gas source to clamp or loosen the conical object at the output end. The lifting module 64 is a telescopic cylinder, the first jaw assembly 62 is fixedly connected to the output end of the lifting module 64 through bolts, the second jaw assembly 63 is fixedly connected to the sorting bin 61, the output ends of the first jaw assembly 62 and the second jaw assembly 63 both pass through the outer wall of the sorting bin 61 and extend into the first channel, and the lifting module 64 is fixedly connected to the sorting bin 61 through bolts.

[0084] The gate mechanism 70 includes a baffle 71 and a gate displacement module 72. The sorting bin 61 is located at the opening of the first channel away from the first conduit 20. The first jaw assembly 62 is fixedly connected to the base 90. The baffle 71 is a flat plate structure. The baffle 71 is fixedly connected to the output end of the gate displacement module 72 by bolts. The gate displacement module 72 is used to control the baffle 71 to slide at the opening of the first channel to open or close the first channel. The gate displacement module 72 can be a telescopic cylinder, or an electromagnetic telescopic or lead screw telescopic structure. In this embodiment, since the nozzle assembly 40, the first jaw assembly 62, the second jaw assembly 63 and the lifting module 64 all use air source as power, the gate displacement module 72 is preferably a telescopic cylinder.

[0085] The sensing module 65 can be a photoelectric detection sensor or a proximity sensor. In this embodiment, the sensing module 65 is a photoelectric detection sensor. The sensing module 65 includes a light beam transmitting end and a light beam receiving end. The light beam transmitting end and the light beam receiving end are mirror-symmetrically arranged. When there is no conical object between the light beam transmitting end and the light beam receiving end, the light beam generated by the light beam transmitting end directly enters the light beam receiving end. When the conical object is located between the light beam receiving end and the light beam transmitting end, the conical object blocks the light beam, so that the light beam receiving end cannot receive the light beam.

[0086] When controlling the conical objects to be discharged one by one, the conical objects fall into the inner side of the sorting bin 61 and are blocked by the baffle 71. The lifting module 64 senses the conical objects. The second jaw assembly 63 clamps the lower conical object, and the first jaw assembly 62 clamps the upper conical object. Then the lifting module 64 lifts the second jaw assembly 63, and the two connected conical objects are separated. At this time, the gate displacement module 72 controls the baffle 71 to retract. The second jaw assembly 63 releases the lower conical object. The lower conical object is discharged from the sorting bin 61 under the action of gravity and the airflow in the sorting bin 61. After the sensing module 65 recognizes the discharge of the lower conical object, the gate displacement module 72 controls the baffle 71 to extend and block the opening of the first channel. The lifting module 64 retracts, and the second jaw assembly 63 releases. The conical object on the second jaw assembly 63 and the conical object in the first conduit 20 fall into the sorting bin 61. The first jaw assembly 62, the second jaw assembly 63, the second jaw assembly 63 and the gate displacement module 72 perform the next separation action.

[0087] In this embodiment, the first jaw assembly 62, the second jaw assembly 63, the second jaw assembly 63, and the gate displacement module 72 are all controlled by a control mechanism, such as an industrial computer.

[0088] The thin-walled and lightweight conical object is a hollow object. Two conical objects with the same traveling direction and their axes in a straight line (coaxial direction), the small cone of the following conical object will fit into the large cone bottom of the leading conical object, forming a "nesting" phenomenon. When the two conical objects are nested, they need to be separated to achieve orderly discharge. Therefore, in this embodiment, a sorting mechanism 60 and a gate mechanism 70 are provided to achieve the orderly discharge of the conical objects.

[0089] As a preferred implementation manner in this embodiment, the device further includes:

[0090] A steering mechanism 80 for changing the advancing direction of the cone. The steering mechanism 80 is provided with a bent second channel, and the second channel is communicated with the first channel. The second channel is a right-angle channel or an obtuse-angle channel.

[0091] Specifically, in this embodiment, the first conduit 20 is a bent pipe structure, and the first channel is arranged vertically. In order to change the discharge direction of the conical object to the horizontal direction, the steering mechanism 80 is provided in this embodiment. The steering mechanism 80 includes a steering chamber 81, a second conduit 82, and an inclined block 83. The second conduit 82 is a hollow shell structure, and the inclined block 83 is a block. A commutation inclined surface is provided on the inclined block 83. The commutation inclined surface and the inner wall of the steering chamber 81 form a second channel. The angle of the second channel is a right angle or an obtuse angle. One end of the second channel is communicated with the first channel, and the other end of the second channel is communicated with the second conduit 82. The second conduit 82 is a straight pipe. In this embodiment, the steering chamber 81 is fixed by welding or screwing a plate-like structure. The inclined block 83 is a triangular block, and the commutation inclined surface on the inclined block 83 is a straight inclined surface or an arc-shaped surface. The second channel is a right-angle channel. The second conduit 82 and the steering chamber 81 are fixedly connected by bolts. The steering chamber 81 is fixedly connected to the base 90, and the steering chamber 81 is fixedly connected to the sorting chamber 61.
