Description

Technical Field

[0001] This utility model relates to the field of material sorting technology, and in particular to a device for feeding conical objects into a conduit for sorting. Background Technology

[0002] In the injection molding industry, after liquid plastic solidifies in the mold, the conical plastic parts fall randomly into the turnover box at the bottom of the injection molding machine. The conical plastic parts in the turnover box are chaotic and disordered. When transporting the conical objects to the next process, it is necessary to ensure that the conical parts are neatly distributed and to sort them.

[0003] The diameter of the cone apex is smaller than the diameter of the cone base. When the cone enters a gradually narrowing guide channel from a container with a planar area several times larger than the cone itself, the cone will get stuck in the area of ​​the resting dimension when the cross-sectional width of the guide channel equals the resting dimension. This prevents the cone from continuing to advance into the guide channel, causing a jamming problem. Therefore, this application proposes a device for feeding cones into a guide channel for sorting. Utility Model Content

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0052] Example 1

[0053] like Figures 1 to 4 As shown in the figure, one embodiment of the present invention provides a device for feeding conical objects into a conduit for sorting. The device includes a conical chute 10, a first conduit 20, a swing mechanism 30, and an air nozzle assembly 40. The conical chute 10 is a material trough that gradually tapers 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. The top end of the conical chute 10 is provided with a closed structure near the small end and an open structure near the large end. The first conduit 20 is fixedly connected to the front cover plate 15 and communicates 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 and 2 times the resting size of the conical object. The swing mechanism 30 includes a swing shaft 31 and a swing motor 32. The swing shaft 31 is rotatably connected to the conical chute 10. The swing motor 32 is used to drive the swing shaft 31 to swing. The air nozzle assembly 40 is fixedly connected to the swing shaft 31 in a suspended manner through a cantilever 41. After the air source is turned on, the air nozzle assembly 40 blows out airflow pointing towards the first conduit 20.

[0054] In this embodiment, when arranging the conical object, the conical object is poured into the conical chute 10. The conical object is randomly distributed in the conical chute 10. The air nozzle assembly 40 is connected to an air source. The swing motor 32 and the air source are started, and the air nozzle assembly 40 blows air. The swing motor 32 drives the air nozzle assembly 40 to swing in the conical chute 10 through the swing shaft 31 and the cantilever 41. The airflow blown by the air nozzle assembly 40 forms a vortex in the closed part of the conical chute 10, agitating the conical object in the conical chute 10. At the same time, the airflow forms a positive pressure in the conical chute 10, driving the first conduit 2... A conical object at the opening 0 enters the first conduit 20. Since the inner diameter of the first conduit 20 is greater than 1 times the resting size of the conical object but less than 2 times the resting size of the conical object, two conical objects cannot enter the first conduit 20 at the same time. Therefore, under the action of airflow, the conical objects in the conical chute 10 enter the first conduit 20 sequentially and are arranged in the first conduit 20. Due to the flow of gas, the conical objects are also pushed and moved within the first conduit 20 by the airflow. The swing of the nozzle assembly 40 can cause the airflow to agitate the conical objects located in the conical chute 10, preventing multiple conical objects from blocking the opening of the first conduit 20.

[0055] The device for feeding conical objects into a conduit for sorting disclosed in this embodiment of the invention sets the conical chute 10 into a longitudinally tapered conical structure and sets its top opening as a semi-closed opening. When sorting the conical objects, the air nozzle assembly 40 located in the conical chute 10 generates an oscillating airflow to agitate the conical objects and form positive pressure at the closed end of the conical chute 10, blowing the conical objects in the conical chute 10 into the first conduit 20 in sequence, thereby solving the problem of material jamming. Compared with the prior art, this invention can greatly reduce the frequency of material jamming during the feeding process of conical objects.

[0056] Specifically, in this embodiment, such as Figure 3 As shown, the conical chute 10 is a rhomboid chute. The conical chute 10 is composed of a three-dimensionally inclined first inclined plate 11 and a second inclined plate 12, and a front cover plate 15 and a rear cover plate 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 transverse V-shaped structure. Two of each of the first inclined plate 11 and the second inclined plate 12 are provided, and the two first inclined plates 11 and the two second inclined plates 12 are mirror images of each other to form a conical chute structure. The first inclined plate 11 and the second inclined plate 12 are perpendicular to the horizontal plane. The included angles are all greater than the angle of repose of the conical object. The two mirror-arranged first inclined plates 11 form a V-shaped groove structure with an upward opening. 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 with a semi-closed opening. The first cover plate 13 and the second cover plate 14 are coplanar. The second cover plate 14 forms a mouth structure with a semi-closed opening.

[0057] Any solid object on an inclined plane will have different angles of repose depending on its shape and the potential of its center of gravity. For example, a spherical object, due to its spherical shape, will roll on the plane when the angle between the spherical object and the horizontal plane is slightly greater than 0°. The angle between the spherical object and the horizontal plane is the angle of repose. Another example is a rectangular cube, which, due to its rectangular shape, has only one plane in contact with the plane. The kinetic energy required for the cube to slide on the plane must be greater than the frictional force between the rectangular object and the plane. When the plane forms an angle greater than 0° with the horizontal plane, the kinetic energy generated by the potential of the rectangular object must be greater than the frictional force between the rectangular object and the plane for the cube to slide on the plane. This angle greater than 0° is the angle of repose.

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

[0059] Preferably, the trough 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 downwards, 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] In a preferred embodiment of this invention, the first inclined plate 11, the second inclined plate 12, and the first cover plate 13 are an integral structure. The first inclined plate 11, the second inclined plate 12, and the first cover plate 13 are formed into half of the conical chute 10 by 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 embodiments 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-groove. The processing method of the conical chute 10 in this embodiment is simpler, therefore, a rhomboid groove structure is preferred.

[0062] As another implementation method in this embodiment, such as Figure 8 As shown, the conical chute 10 also includes a straight side plate 17, which is fixedly connected to the first inclined plate 11. The straight side plate 17 and the second inclined plate 12 constitute the side plate structure of the conical chute 10. The straight side plate 17 is located on the side closer to the rear cover plate 16, and 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 set vertically, and the straight side plate 17, the rear cover plate 16 and the first cover plate 13 form the opening 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, the front cover plate 15 is provided with a pipe interface, and the first conduit 20 is fixed to the pipe interface by a clamp.

[0064] The first conduit 20 can also be a square tube. 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 must be larger than the diameter of the large end of the cone and smaller than the resting size of the cone.

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

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

[0067] Preferred, such as Figure 7 As shown, the swing mechanism 30 is also provided with a protective cover 34. The protective cover 34 is a square shell structure. The protective cover 34 covers the swing mechanism 30 and is fixedly connected to the swing mechanism 30 by bolts.

[0068] like Figure 4 and Figure 5 As shown, the cantilever 41 includes a first support on the rocker shaft 31 and a second support on the air nozzle assembly 40. The first support includes a fixing sleeve and a connecting strip. The fixing sleeve is a cylindrical shape with openings at both ends and is fixed to the rocker shaft 31 by screws. The connecting strip and the fixing sleeve are integral structures, and the connecting strip is perpendicular to the axis of the fixing 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 fitted onto the air nozzle assembly 40 by an interference fit.

[0069] The air nozzle assembly 40 is an air nozzle structure that connects to an air source in the prior art, such as a circular tube-shaped air nozzle structure.

[0070] In a preferred embodiment of this invention, the angle between the nozzle assembly 40 and the bottom of the conical chute 10 is approximately -5° to 5°, and the air pressure inside the nozzle assembly 40 is approximately 0.4 to 0.7 MPa.

[0071] As a preferred embodiment of this example, Figures 3 to 6 As shown, a grid curtain 18 is also provided inside the conical chute 10. The grid curtain 18 is composed of multiple grid curtain rods 181. The grid curtain 18 is fixedly connected to 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. Multiple grid curtain rods 181 are fixedly connected to the curtain frame 19 by 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. Multiple connecting plates 191 are connected sequentially by bolts. The connecting plate 191 near the rear cover plate 16 is fixedly connected to the rear cover plate 16 by bolts. The connecting plate 191 is used to avoid the swing shaft 31. The grid curtain 18 is used to prevent conical objects 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] In a preferred embodiment of this invention, without the grille 18, a fixed nozzle is provided on the rear cover plate 16. The fixed nozzle continuously sprays airflow to prevent conical objects 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 15-25mm.

[0073] Example 2

[0074] like Figures 9 to 12 As shown, as another embodiment of the present invention, this embodiment differs from Embodiment 1 in that the device further includes:

[0075] A sorting mechanism 60 is fixedly connected to the outlet of the first conduit 20 and is used to control the discharge of the conical objects one by one to prevent the conical objects from stacking.

[0076] A gate mechanism 70 is fixedly connected to the outlet of the sorting mechanism 60 and is used to temporarily block the discharge of the conical object in order to cooperate with the sorting mechanism 60.

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

[0078] The sorting chamber 61 has a first channel that runs through it. One end of the first channel is connected to the end of the first conduit 20 away from the conical chute 10. The gate mechanism 70 is used to intermittently close the end of the first channel away from the first conduit 20.

[0079] The first gripper assembly 62 is located at one end of the first channel near the first conduit 20 and is used to grip overlapping conical objects.

[0080] The second gripper assembly 63 is located inside the first channel and is used to grip the conical object on the gate mechanism 70. The distance between the second gripper assembly 63 and the first gripper assembly 62 is greater than the height of one conical object and less than the height of two conical objects.

[0081] A lifting module 64, wherein the first gripper assembly 62 is fixedly connected to the output end of the lifting module 64, and the lifting module 64 is used to lift the second gripper assembly 63 to separate adjacent conical objects;

[0082] The sensing module 65 is used to identify conical objects entering the first channel to generate control signals.

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

[0084] The gate mechanism 70 includes a baffle 71 and a gate displacement module 72. The sorting chamber 61 is located at the opening of the first channel away from the first conduit 20. The first gripper 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 air nozzle assembly 40, the first gripper assembly 62, the second gripper 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 beam transmitting end and a beam receiving end. The beam transmitting end and the beam receiving end are mirror images of each other. When there is no conical object between the beam transmitting end and the beam receiving end, the beam generated by the beam transmitting end shines directly into the beam receiving end. When the conical object is located between the beam receiving end and the beam transmitting end, the conical object blocks the beam, so that the beam receiving end cannot receive the beam.

[0086] When the conical objects are discharged one by one, they fall into the sorting chamber 61 and are blocked by the baffle 71. The lifting module 64 senses the conical objects, the second gripper assembly 63 clamps the lower conical object, and the first gripper assembly 62 clamps the upper conical object. Then, the lifting module 64 lifts the second gripper assembly 63, separating the two connected conical objects. At this time, the gate displacement module 72 controls the baffle 71 to retract, and the second gripper assembly 63 releases the lower conical object. The lower conical object is then released by gravity and the air pressure inside the sorting chamber 61. Under the action of the flow, the conical object is discharged from the sorting chamber 61. After the sensing module 65 detects the discharge of the conical object located below, the gate displacement module 72 controls the baffle 71 to extend and block the opening of the first channel. The lifting module 64 retracts, the second gripper assembly 63 is released, and the conical object on the second gripper assembly 63 and the conical object located in the first conduit 20 fall into the sorting chamber 61. The first gripper assembly 62, the second gripper assembly 63, the second gripper assembly 63 and the gate displacement module 72 perform the next separation action.

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

[0088] Thin-walled, lightweight conical objects are hollow. When two conical objects travel in the same direction and their axes are aligned (coaxial), the smaller cone of the following conical object will fit into the base of the larger cone of the preceding conical object, forming a "nesting" phenomenon. When the two conical objects are nested, they must be separated to achieve orderly discharge. Therefore, in this embodiment, a sorting mechanism 60 and a gate mechanism 70 are provided to achieve orderly discharge of the conical objects.

[0089] In a preferred embodiment of this invention, the device further includes:

[0090] A steering mechanism 80 is used to change the forward direction of the cone. The steering mechanism 80 has a curved second channel that is connected to 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 vertically arranged. To change the discharge direction of the conical object to a horizontal direction, this embodiment provides a steering mechanism 80. 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 block-shaped. A reversing inclined surface is provided on the inclined block 83. The reversing 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 connected to the first channel, and the other end of the second channel is connected to the second conduit 82. The conduit 82 is a straight pipe. In this embodiment, the turning chamber 81 is a plate structure fixed by welding or screw connection. The inclined block 83 is a triangular block. The reversing inclined surface on the inclined block 83 is a straight inclined surface or an arc surface. The second channel is a right-angle channel. The second conduit 82 and the turning chamber 81 are fixedly connected by bolts. The turning chamber 81 is fixedly connected to the base 90, and the turning chamber 81 is fixedly connected to the sorting chamber 61. The lower end of the conical object falling into the second channel falls onto the inclined block 83 and receives the reaction force of the inclined surface on the inclined block 83, causing the conical object to turn and be discharged into the second conduit 82 under the action of airflow.

[0092] In this embodiment, the base 90 is flat, and the steering compartment 81 is fixed to the base 90 by bolts.
