Description

Technical Field

[0001] The invention belongs to a material transport device, and in particular relates to a controllable dial-type spherical material stepping transport device. Background Art

[0002] In the industrial age, mass production on production lines has become the norm. For some large quantities of accumulated workpieces, they sometimes need to be sorted out one by one. If this work is done manually, the efficiency of the production line will be greatly reduced. For conveying spherical materials, such as ping-pong balls, tennis balls, and golf balls, pipelines or a dial-type spherical material conveyor can be used. For example, Chinese Patent No. CN110040492A discloses a "controllable dial-type spherical material stepping conveyor device." This device utilizes a track module, a dial module, and a drive module. The dial module is disposed within the track module and, together with the track module, forms a plurality of spherical material receiving slots. The spherical materials are gradually moved by the rotation of the dial module. Although this stepping conveyor device can convey spherical materials, the material track is disposed outside the track module, increasing the space occupied by the stepping conveyor device. Furthermore, in order to efficiently separate large quantities of spherical materials, the biggest problem to be considered is material jamming. During the process of materials entering a smaller pipe from a larger space and during the process of rapidly changing from a track with a smaller curvature to a track with a larger curvature, if these adjustments are not controlled, the materials may become jammed or jammed with the mechanism, preventing sorting or even causing damage to the mechanism.

[0010] Preferably, each vertical guide rail is provided with a plurality of guide rollers along its length direction, and the guide rollers are rotatably connected to the vertical guide rail to reduce the friction between the spherical material and the ascending track.

[0011] Preferably, the track module further comprises a track baffle and an anti-jamming bearing; the track baffle and the anti-jamming bearing are installed above the entrance of the secondary transmission track.

[0012] Preferably, the driving module includes a motor base, a motor and a driving gear; the motor is vertically mounted on the motor base, and the output shaft of the motor and the driving gear are connected by a key.

[0016] The beneficial effects of the present invention compared with the prior art are:

[0017] 1. In the present application, the outlet of the material conveying device is arranged at the center position of the dial module. After the dial module is sequentially transmitted, the spherical material enters the ascending track from the primary transmission track and the secondary transmission track, and is discharged from the top of the ascending track under the squeeze of the spherical material below; setting the track outlet at the center position can save a lot of dial volume, while increasing the symmetry of the mechanism, and the structure is relatively more compact.

[0018] 2. In this application, the radius of the primary transmission track is larger, while the radius of the secondary transmission track is smaller. This can guide the spherical material into the center of the dial, ensuring that the curvature of the two tracks with different curvatures is the same at the junction, preventing sudden changes in direction and avoiding the phenomenon of the material getting stuck or jumping under force. The curvature of the junction between the rising track and the planar two-dimensional track changes smoothly to ensure that the force on the material is continuous and does not jump when it leaves the two-dimensional plane and rises. At the same time, the overall material travel route is designed to be symmetrical, that is, the projection of the speed direction of the material when it leaves the planar track on the plane is exactly the central axis of the track, and the connectors of the fixed track are also designed to be symmetrically distributed to improve the force condition.

[0019] 3. This application incorporates a track baffle and anti-jamming bearings, both of which prevent multiple layers of material from simultaneously entering the secondary transmission track and becoming stuck. Furthermore, in the primary transmission track, each shift fork is equipped with a small bearing. The outer ring of the small bearing abuts against the center of the spherical material slightly above it, exerting a downward and forward force on the spherical material. This reduces the possibility of the spherical material jumping up and stacking, leading to jamming, during its circular motion. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0031] See also Figures 1 to 8 , an embodiment of the present application provides a controllable dial-type spherical material stepping conveying device, which includes a drive module A, a track module B and a dial module C.

[0032] See also Figure 3Drive module A is used to drive the rotation of the drive end of dial module C. It includes a motor base 1, motor 2, and drive gear 3. Motor 2 is vertically mounted on motor base 1, with a keyed connection between the motor 2 output shaft and drive gear 3 to facilitate torque transmission. Drive module A's external drive design facilitates maintenance, disassembly, and replacement of damaged parts. Based on the gear pair's stress characteristics and assembly requirements, the drive gear 3 should be 4-5 mm thicker than the dial ring gear 10.

[0033] See also Figure 5 and Figure 6 , the track module B has a guiding effect on the movement of spherical materials, which includes a mounting base 4, a primary arc guide rail 5, a secondary arc guide rail 6, an ascending track 7, a track baffle 8 and an anti-jamming bearing 9; the ascending track 7 is vertically mounted at the center of the mounting base 4 to reduce the space occupied by the conveying device; the primary arc guide rail 5 and the secondary arc guide rail 6 are sequentially arranged along the circumferential direction of the ascending track 7 and fixed on the mounting base 4, and the dial module C is sleeved on the primary arc guide rail 5 and the secondary arc guide rail 6 and fixedly mounted on the mounting base 4; a planar primary transmission track is formed between the dial module C and the primary arc guide rail 5, and the inner edge of the primary transmission track is fixed on the mounting base 4; Several material transfer grooves are formed in the circumferential direction, and each material transfer groove accommodates a spherical material; a planar secondary transfer track is formed between the primary arc guide rail 5 and the secondary arc guide rail 6, and the primary transfer track, the secondary transfer track and the ascending track 7 are sequentially connected along the movement direction of the spherical material; wherein, the primary transfer track is used for the separation and circumferential transfer of spherical materials, the secondary transfer track is used for the change of direction of the circumferential movement of spherical materials, and the ascending track is used for the discharge of spherical materials; the track baffle 8 and the anti-jamming bearing 9 are installed above the entrance of the secondary transfer track, wherein the anti-jamming bearing 8 extends toward the entrance to prevent the stacking and jamming of spherical materials.

[0034] Among them, the ascending track 7 is used to change the output direction of the spherical material and make the track outlet at the center position of the dial. The ascending track 7 includes two vertical support frames 7-1 and two vertical guide rails 7-2. The two vertical support frames 7-1 are arranged opposite to each other and are located on both sides of the entrance of the ascending track 7. The two vertical guide rails 7-2 are arranged opposite to each other at the position between the two vertical support frames 7-1, and each vertical guide rail 7-2 is fixedly connected to the vertical support frames 7-1 on both sides; one of the vertical guide rails 7-2 is arranged opposite to the entrance of the ascending track 7, and the lower end of one of the vertical guide rails 7-2 is arranged into an arc-shaped slope, and the arc-shaped slope extends to the entrance of the ascending track 7; the other vertical guide rail 7-2 is directly above the entrance of the ascending track 7.

[0035] Furthermore, each vertical guide rail 7-2 is provided with a plurality of guide rollers 7-2-1 along its length direction, and the guide rollers 7-2-1 are rotatably connected to the vertical guide rail 7-2 to reduce the friction between the spherical material and the ascending track 7.

[0036] Among them, the first-level arc guide rail 5 has a guiding effect on the circumferential movement of the spherical material. The length of the first-level arc guide rail 5 is longer than that of the second-level arc guide rail 6, and it surrounds most of the circumferential part of the ascending track 7 to ensure that more spherical materials can enter the material transmission trough; an opening is left between the head end and the tail end of the first-level arc guide rail 5 (the head end and the tail end are determined by the movement direction of the spherical material), and is aligned with the entrance of the ascending track 7; the tail end of the second-level arc guide rail 6 is connected to the head end of the first-level arc guide rail 5, and the head end of the second-level arc guide rail 6 extends to the tail end of the first-level arc guide rail 5. The curvature radius of the second-level arc guide rail 6 is greater than the curvature radius of the first-level arc guide rail 5. Therefore, there is a certain distance in the radial direction between the head end of the second-level arc guide rail 6 and the tail end of the first-level arc guide rail 5, which is used as the entrance of the secondary transmission track. The second-level arc guide rail 6 is used to change the direction of the circumferential movement of the spherical material so that the spherical material can smoothly enter the ascending track 7.

[0037] Furthermore, the primary arc guide rail 5 and the secondary arc guide rail 6 have the same structural form, and the primary arc guide rail 5 is taken as an example for explanation; the primary arc guide rail 5 includes an arc guide rail 5-1 and a plurality of rollers 5-2 arranged along the length direction of the arc guide rail 5-1, and the rollers 5-2 are installed on the upper surface of the arc guide rail 5-1 and are rotatably connected to the arc guide rail 5-1; wherein the outer cylindrical surface of the roller 5-2 protrudes from the outer side wall of the arc guide rail 5-1; the rolling direction of the roller 5-2 is the same as the transmission direction of the spherical material, and is used to reduce the friction force exerted on the spherical material during the transmission process. On the one hand, it can reduce the wear of the spherical material, and on the other hand, it can reduce the output torque of the drive module A.

[0038] Among them, in order to prevent multiple layers of materials from getting stuck when entering the secondary transmission track at the same time, a track baffle 8 and an anti-jamming bearing 9 are designed at the place where the material changes direction and enters the secondary track. The anti-jamming bearing 9 is arranged vertically in space with the arc curve of the material transmission path. The height of the anti-jamming bearing 9 is controlled between 1.2 and 1.5 times the diameter of the spherical material, and the diameter of the anti-jamming bearing 9 is about 1 / 3 of the diameter of the spherical material.

[0039] See also Figure 4The dial module C is annular and is sleeved on the outside of the primary arc guide rail 5 and the secondary arc guide rail 6, and is fixedly connected to the mounting base plate 4; the dial module C includes a dial gear ring 10, a shift fork ring 11, an annular support plate 12 and a large bearing, the annular support plate 12 is sleeved on the outer ring of the large bearing and is fixedly connected to the mounting base plate 4; the dial gear ring 10 and the shift fork ring 11 are respectively arranged above and below the annular support plate 12, and are respectively fixedly connected to the inner ring of the large bearing; the dial A plurality of shift forks 11-1 are arranged along the circumferential direction on the inner wall of the fork ring 11, and the number of the shift forks 11-1 is preferably 8 to 10; every two adjacent shift forks 11-1 and the outer wall of the primary arc guide rail 5 enclose a nearly circular material transfer groove; the driving gear 3 of the driving module A is engaged with the dial gear ring 10 to form a transmission gear pair; the dial gear ring 10 drives the shift fork ring 11 to rotate under the transmission of the driving gear 3, and the shift fork ring 11 drives the spherical material in the material transfer groove to perform circular motion.

[0040] Among them, the annular support plate 12 is rectangular with a circular through hole in the middle for installing a large bearing; the annular support plate 12 is fixed to the mounting base plate 4 through 10 copper columns. While effectively supporting the dial plane, it strengthens the rigidity of the track plane and improves the deformation of the bottom surface caused by the downward force of the spherical material.

[0041] Here, the inner diameter of the material transmission trough is r, the diameter of the spherical material is d, and 2d≥r≥d, so as to ensure that each material transmission trough can only accommodate one spherical material, and the material transmission trough has a stronger wrapping property for the spherical material.

[0042] Furthermore, a small bearing 11-2 is rotatably installed at the bottom of each fork 11-1. The diameter of the small bearing 11-2 is 1 / 5 of the diameter of the spherical material. The outer ring of the small bearing 11-2 abuts against the upper center of the spherical material, applying a downward and forward force to the spherical material, so as to reduce the possibility of the spherical material jumping up and stacking until it gets stuck during the circular motion.

[0043] Furthermore, the height of the shift fork ring 11 is higher than the height of the primary arc guide rail 5 and the secondary arc guide rail 6, so as to reduce the possibility of the spherical material jumping up and stacking until it gets stuck during the circular motion.

[0044] The working process of the present invention is further described below to further demonstrate the working principle and advantages of the present invention:

[0045] First, pour a large amount of spherical materials between the dial module C and the track module B. At this time, due to the design of the size of the material transmission groove, each material transmission groove accommodates a spherical material. Start the motor 2, drive the drive gear 3 in the module A to rotate, and drive the fork ring 11 to rotate. At this time, the small bearing 11-2 on the fork 11-1 abuts against the spherical surface of the spherical material and gives it a downward and forward thrust. The spherical material in the material transmission groove performs circular motion. When the first spherical material enters the secondary transmission track from the primary transmission track, since the fork ring 11 no longer generates thrust on the spherical material, the spherical material continues to move along the secondary transmission track by inertia. As the spherical material in the secondary transmission track increases, the next spherical material will give thrust to the previous spherical material, so that the spherical material can enter the ascending track 7 and be discharged from the outlet. In the present application, the outlet of the material conveying device is arranged at the center position of the dial module C, that is, the spherical material enters the material conveying groove formed by the dial module C and the track module B, and is sequentially transmitted by the dial module C, so that the spherical material enters the rising track 7 and is discharged from the top of the rising track 7 under the pressure of the spherical material below; setting the track outlet at the center position can save a lot of dial volume, while increasing the symmetry of the mechanism, and the structure is relatively more compact.

[0046] In the present application, a primary transmission track is formed between the dial module C and the primary arc guide rail 5, and a secondary transmission track is formed between the primary arc guide rail 5 and the secondary arc guide rail 6. The primary transmission track and the secondary transmission track are connected to the rising track 7. Under the action of the dial module C, the spherical material changes tracks in a two-dimensional plane, that is, it enters the rising track 7 from the primary transmission track and the secondary transmission track in turn; wherein, the radius of the primary transmission track is larger, and the radius of the secondary transmission track is smaller, and the function is to guide the spherical material into the center of the dial, ensuring that the curvature of the two tracks with different curvatures is the same at the junction, without sudden changes in direction, and avoiding the phenomenon of material getting stuck or jumping up due to force; by smoothly changing the curvature at the junction of the rising track and the two-dimensional plane track, it is ensured that the force is continuous and does not jump at the moment when the material leaves the two-dimensional plane and rises. At the same time, the overall material travel route is designed to be symmetrical, that is, the projection of the speed direction of the material when it leaves the plane track on the plane is exactly the central axis of the track, and the connectors of the fixed track are also designed to be symmetrically distributed to improve the force condition.

[0047] In this application, if the area around the outlet is not smooth enough due to processing problems or the spherical material itself is relatively rough, polytetrafluoroethylene tape can be evenly pasted there to ensure lubrication.
