Description

Technical Field

[0001] This invention belongs to the field of toy tire processing technology, and more specifically, relates to a toy tire assembly device. Background Technology

[0002] Currently, toy tires are generally produced using injection molding. After injection molding, the sprue needs to be removed before they are assembled with the wheel hub.

[0003] In the existing technology, the sprue removal and wheel assembly are carried out in two separate machines. After the tires are injection molded, they are transported to the sprue removal machine to remove the sprues. Then the tires with the sprues removed are transported to the assembly machine to be assembled with the wheel hub. Because there are many transport processes, the entire assembly process requires a lot of manual intervention, which will inevitably affect the assembly efficiency.

[0004] Therefore, the technical problem to be solved by this application is: how to realize the continuous processing of the sprue of toy tires and the assembly of wheel hubs. Summary of the Invention

[0005] The main objective of this invention is to provide a toy tire assembly device that can remove the sprue from toy tires and complete the wheel hub assembly.

[0006] According to a first aspect of the present invention, a toy tire assembly apparatus is provided, comprising a frame, wherein a sprue unit and an assembly unit are provided on the frame;

[0007] The drain unit includes a first pipe, the bottom of which is a punching station. Tires are stacked vertically in the first pipe, with the axial direction of the tires being a first direction. One end of the punching station along the first direction is provided with a punching cutter, and the other end of the punching station along the first direction is provided with a cleaning hole. The punching cutter moves along the first direction under the drive of a first cylinder, punching the sprue of the tires in the punching station into the cleaning hole.

[0008] The assembly unit includes a second pipe and a third pipe. The upper end of the second pipe receives the tire with the sprue removed, and the lower end of the second pipe is the assembly station.

[0009] A pusher module is provided below the third pipe. The wheel hubs are stacked vertically in the third pipe. The pusher module pushes the wheel hubs output from the third pipe into the tires at the assembly station.

[0010] In the aforementioned toy tire assembly equipment, the second pipe is located between the first pipe and the first cylinder;

[0011] The second pipe has a material passage hole on the side close to the first pipe and a limiting hole on the side of the second pipe away from the first pipe. The material passage hole, the limiting hole and the cleaning hole are arranged coaxially. The punching tool passes through the limiting hole and the material passage hole in sequence and enters the first pipe.

[0012] The diameters of the limiting hole and the clearing hole are both adapted to the outer diameter of the punching tool, and the diameter of the material passage hole is larger than the outer diameter of the tire.

[0013] In the toy tire assembly equipment described above, the direction that is perpendicular to and horizontal to the first direction is the second direction;

[0014] A movable seat is provided below the third pipe, and the movable seat has a notch for accommodating the wheel hub. The movable seat moves in a second direction under the drive of the second cylinder. The movable seat receives the wheel hub below the third pipe and sends the wheel hub to a preset position.

[0015] The pushing module includes a push rod and a third cylinder that drives the push rod to move in a first direction. The push rod pushes the wheel hub in a preset position to the assembly station.

[0016] In the aforementioned toy tire assembly equipment, a guide module is provided between the preset position and the assembly station;

[0017] The guide module includes a mounting plate and a fourth cylinder that drives the mounting plate to move along a first direction. The mounting plate is provided with a positioning hole for the wheel hub to pass through. The axis of the positioning hole is parallel to the first direction. Multiple elastic paddles are arranged circumferentially around the positioning hole on the mounting plate. The limiting space formed by the multiple elastic paddles gradually contracts along the direction closer to the assembly station.

[0018] Driven by the fourth cylinder, the end of the elastic paddle away from the mounting plate can be inserted into the wheel hub mounting hole of the tire.

[0019] In the aforementioned toy tire assembly equipment, the end of the elastic lever near the mounting plate is hinged to the mounting plate. The mounting plate is provided with springs that correspond one-to-one with the elastic levers. The springs cause the end of the elastic lever away from the mounting plate to swing in a direction close to the axis of the positioning hole.

[0020] In the aforementioned toy tire assembly equipment, a limiting part is provided on the side of the elastic paddle facing away from the axis of the positioning hole, and a groove is provided on the mounting plate to accommodate the limiting part. A stud is fixed in the groove, and the head of the stud is located on the side of the limiting part away from the assembly station. The spring is sleeved on the stud and located between the head of the stud and the limiting part.

[0021] In the aforementioned toy tire assembly equipment, a first baffle is provided below the assembly station, and the first baffle enters or leaves the second pipe under the drive of the fifth cylinder.

[0022] When the first baffle enters the second pipe, the first baffle carries the tire located in the assembly station.

[0023] In the aforementioned toy tire assembly equipment, a second baffle is provided above the assembly station, and the second baffle enters or leaves the second pipe under the drive of the sixth cylinder.

[0024] When the second baffle enters the second pipe, it can prevent the tire above from falling into the assembly station.

[0025] In the aforementioned toy tire assembly equipment, the cleaning hole is connected to a conveying pipe, and the conveying pipe is inclined downward in a direction away from the cleaning hole.

[0026] One of the above-described technical solutions of the present invention has at least one of the following advantages or beneficial effects:

[0027] In this invention, a punching station is set at the bottom of the first pipe. The punching cutter passes through the second pipe and enters the first pipe to punch the toy tire in the punching station. The outer diameter of the punching cutter is matched with the size of the wheel hub mounting hole of the toy tire, so the sprue on the toy tire can be punched off and pushed to the cleaning hole, allowing the sprue to be discharged from the cleaning hole. The toy tire with the sprue removed will be fitted onto the punching cutter and move with the punching cutter. As the punching cutter retracts, the toy tire moves into the second pipe. Under the restriction of the limiting hole, the toy tire peels off from the punching cutter and falls into the second pipe, thus completing the process of removing the sprue from the toy tire.

[0028] After the sprue is removed, the toy tire moves along the second pipe to the assembly station. The pusher module pushes the wheel hub output from the third pipe into the tire at the assembly station, completing the wheel hub assembly. This achieves continuous processing of sprue removal and wheel hub assembly for the toy tire, improving the assembly efficiency of the toy tire. Attached Figure Description

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The following disclosure provides many different implementations or examples for different ways of implementing the present invention.

[0040] Reference Figures 1 to 6 As shown, in one embodiment of the present invention, a toy tire assembly device includes a frame 1, on which a sprue unit 2 and an assembly unit 3 are provided;

[0041] The drain unit 2 includes a first pipe 21, the bottom of which is a punching station. Tires are stacked in the first pipe 21 in a vertical direction. The axis of the tires is the first direction. One end of the punching station along the first direction is provided with a punching cutter 22, and the other end of the punching station along the first direction is provided with a cleaning hole (not shown in the figure). The punching cutter 22 moves along the first direction under the drive of the first cylinder 23.

[0042] Assembly unit 3 includes a second pipe 31, which is located between the first pipe 21 and the first cylinder 23;

[0043] The second pipe 31 has a material passage hole 311 on the side close to the first pipe 21, and a limiting hole 312 on the side of the second pipe 31 facing away from the first pipe 21. The material passage hole 311, the limiting hole 312, and the cleaning hole are arranged coaxially. The diameter of the limiting hole 312 and the diameter of the cleaning hole are both adapted to the outer diameter of the punching tool 22. The diameter of the material passage hole 311 is larger than the outer diameter of the toy tire.

[0044] The cross-sections of the first pipe 21 and the second pipe 31 are both rectangular, which can restrict the posture of the toy tire. Therefore, when the toy tire is in the punching station, its axial direction will always be in the first direction, ensuring that the punching cutter 22 can punch onto the sprue of the toy tire. When the punching cutter 22 moves, it will pass through the limiting hole 312 and the material passage hole 311 in sequence and enter the first pipe 21. The outer diameter of the punching cutter 22 is adapted to the size of the wheel hub mounting hole of the toy tire, so the sprue on the toy tire can be punched off and pushed to the cleaning hole, allowing the sprue to be discharged from the cleaning hole. The toy tire with the sprue removed will be fitted onto the punching cutter 22 and move with the punching cutter 22. As the punching cutter 22 retracts, the toy tire passes through the material passage hole 311 and moves into the second pipe 31. Under the restriction of the limiting hole 312, the toy tire peels off from the punching cutter 22 and falls into the second pipe 31, thus completing the sprue removal process of the toy tire.

[0045] Assembly unit 3 also includes a third pipe 32, and the lower end of the second pipe 31 is an assembly station;

[0046] Below the third pipe 32 is a pusher module 33, and the wheel hubs are stacked in the third pipe 32 in a vertical direction; the cross-section of the third pipe 32 is also rectangular, which can restrict the posture of the wheel hubs and make the axial direction of the wheel hubs parallel to the first direction.

[0047] The direction perpendicular to and horizontal to the first direction is the second direction; a movable seat 34 is provided below the third pipe 32, and the movable seat 34 is provided with a notch 341 for accommodating the hub. The movable seat 34 moves along the second direction under the drive of the second cylinder 35.

[0048] The movable seat 34 first positions the notch 341 below the third pipe 32 to receive the wheel hub. After the wheel hub enters the notch 341, the second cylinder 35 pushes the movable seat 34 to move the notch 341 to the preset position. At this time, other parts of the movable seat 34 will block the bottom of the third pipe 32 to prevent other wheel hubs from falling out.

[0049] The pusher module 33 includes a pusher rod 331 and a third cylinder 332 that drives the pusher rod 331 to move in a first direction. The pusher rod 331 is coaxial with the wheel hub in the preset position. After the sprue is removed, the toy tire moves along the second pipe 31 to the assembly station. The side of the assembly station close to the preset position is open. The third cylinder 332 actuates to push the pusher rod 331 to push the wheel hub in the preset position into the assembly station, so that the wheel hub is assembled into the toy tire. This realizes the continuous processing of sprue removal and wheel hub assembly of the toy tire, and improves the assembly efficiency of the toy tire.

[0050] In this embodiment, a guide module 4 is provided between the preset position and the assembly station;

[0051] The guide module 4 includes a mounting plate 41 and a fourth cylinder 42 that drives the mounting plate 41 to move along a first direction. The mounting plate 41 is provided with a positioning hole 43 for the hub to pass through. The axis of the positioning hole 43 is parallel to the first direction. Multiple elastic paddles 44 are arranged around the positioning hole 43 on the mounting plate 41.

[0052] One end of the elastic lever 44 near the mounting plate 41 is hinged to the mounting plate 41. A limiting part 45 is provided on the side of the elastic lever 44 facing away from the axis of the positioning hole 43. The mounting plate 41 is provided with a groove 46 to accommodate the limiting part 45. A stud 47 is fixed in the groove 46. The head of the stud 47 is located on the side of the limiting part 45 away from the assembly station. A spring 48 is sleeved on the stud 47. The spring 48 is located between the head of the stud 47 and the limiting part 45, thereby causing the end of the elastic lever 44 away from the mounting plate 41 to swing in the direction close to the axis of the positioning hole 43. Therefore, the limiting space formed by multiple elastic levers 44 gradually contracts in the direction close to the assembly station.

[0053] Driven by the fourth cylinder 42, the end of the elastic paddle 44 away from the mounting plate 41 can be inserted into the wheel hub mounting hole of the tire.

[0054] During wheel assembly, the mounting plate 41 first approaches the preset position, and the push rod 331 pushes the wheel hub into the positioning hole 43. The fourth cylinder 42 drives the mounting plate 41 to move towards the assembly station, allowing the end of the elastic paddle 44 away from the mounting plate 41 to be inserted into the wheel hub mounting hole of the toy tire. As the push rod 331 continues to push, the wheel hub enters the limiting space formed by multiple elastic paddles 44. The limiting space forms a guide channel. When the wheel hub moves forward, it will open the elastic paddles 44. The limiting part 45 of 44 compresses the spring 48, and the end of the elastic lever 44 away from the mounting plate 41 contacts the toe opening of the toy tire to expand the diameter of the toe opening of the toy tire, thereby facilitating the wheel hub to enter the toy tire. After the wheel hub is completely entered into the toy tire, the fourth cylinder 42 drives the mounting plate 41 to move away from the assembly station, so that the elastic lever 44 leaves the toy tire. Without the support of the wheel hub, the spring 48 causes the elastic lever 44 to rotate, so that the guide module 4 returns to its initial state.

[0055] In some other embodiments, the elastic paddle 44 may simply be an elastic metal sheet, and can reset itself without the need for an additional spring 48.

[0056] In this embodiment, a first baffle 36 is provided below the assembly station. The first baffle 36 enters or leaves the second pipe 31 under the drive of the fifth cylinder 37.

[0057] A second baffle (not shown in the figure) is provided above the assembly station. The second baffle enters or leaves the second pipe 31 under the drive of the sixth cylinder 38.

[0058] In operation, the fifth cylinder 37 first drives the first baffle 36 into the second pipe 31, and then the sixth cylinder 38 drives the second baffle to leave the second pipe 31, allowing the toy tire in the second pipe 31 to enter the assembly station. At this time, the first baffle 36 can hold the toy tire in the assembly station. The sixth cylinder 38 drives the second baffle into the second pipe 31 to block the top of the assembly station and prevent other toy tires from entering the assembly station. After the wheel hub assembly is completed, the fifth cylinder 37 drives the first baffle 36 to leave the second pipe 31, allowing the assembled toy tire to be discharged from the bottom of the second pipe 31. This cycle repeats.

[0059] In this embodiment, a conveying pipe 24 is connected to the cleaning hole. The conveying pipe 24 is inclined downward in the direction away from the cleaning hole. The water inlet enters the conveying pipe 24 through the cleaning hole. The length of the conveying pipe 24 can be designed according to the size of the machine. It can be directly connected to the external waste frame to discharge the waste gas in time.

[0060] In this embodiment, the upper end of the first pipe 21 can be connected to a corresponding vibratory feeder to continuously input toy tires with unremoved sprues into the first pipe 21, and the upper end of the third pipe 32 can also be connected to a corresponding vibratory feeder to continuously input wheel hubs into the third pipe 32.

[0061] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
