Description

Technical Field

[0001] The present invention relates to the technical field of wheel rim processing, and more particularly to a feeding and conveying device and method for processing a forklift wheel rim. Background Art

[0002] The forklift wheel rim is a component that mounts and supports the tire on the periphery of the wheel, and together with the spokes, forms the wheel. The steel wheel rim is usually made of steel and has the characteristics of wear resistance, corrosion resistance, and impact resistance.

[0003] In the traditional wheel rim rolling production process, the wheel rim steel ring is mostly loaded into the rolling mold area of the rolling machine through a loading device. For example, patent number CN208230763U discloses an automatic loading and unloading device for wheel rim rolling. After the workpiece is fed into the infeed and outfeed plate device using an adjustable feed roller, the infeed and outfeed plate device is controlled by a servo motor and pushed inward along the direction of the screw to reach the rolling position of the rolling machine A. When the rolling is completed, the processed workpiece falls back onto the infeed and outfeed plate device. Under the control of the servo motor, the infeed and outfeed plate device is pushed outward along the direction of the screw to return to the initial position, and then the workpiece located on the infeed and outfeed plate device is transferred to the next process through the flipping mechanism.

[0004] This patent uses a feeding and discharging device and a turning mechanism as the feeding and discharging of workpieces, but the feeding and discharging device is arranged between the adjustable feeding roller and the turning mechanism. After receiving the workpiece, the feeding and discharging device loads it to the rolling position. After the rolling is completed, it returns to the original path and cooperates with the turning mechanism to transfer the workpiece to the next process. Only when the previous workpiece is rolled and transferred to the next process, can the feeding and discharging device receive the next workpiece. The operating flexibility and continuity are poor, and the rolling processing time is extended, which has certain defects.

[0005] Therefore, in view of the above practical problems, a feeding and conveying device and method for forklift wheel rim processing are proposed. Summary of the Invention

[0006] The present invention aims to solve the problem that the traditional upper and lower material conveying structure can only receive the next workpiece after the previous workpiece is rolled and transferred to the next process, resulting in poor operational flexibility and continuity and prolonged rolling processing time. The present invention provides a loading and conveying device and method for forklift wheel rim processing.

[0007] The object of the present invention can be achieved by the following technical solution: a feeding and conveying device used for forklift wheel rim processing, comprising a feeding inclined roller for continuously feeding the rim, and an annular electric guide rail arranged below the side of the feeding inclined roller and perpendicular to the feeding inclined roller;

[0008] A plurality of feeding assemblies are evenly distributed on the annular electric guide rail, which move in an annular circumferential direction and are used to transport the rims. A supporting bracket is installed above the annular electric guide rail and is located at the discharge port of the loading inclined roller conveyor.

[0009] The bottom of the feeding inclined roller is provided with a feeding surface which is inclined downward toward one side of the supporting bracket, and a material shifting assembly is rotatably installed on the feeding inclined roller near the discharge port on one side of the supporting bracket, and the material shifting assembly includes a rotating disk which is rotatably driven and installed on the inner wall of one side of the feeding inclined roller, and a semi-limiting ring which is coaxial with it and consistent with the feeding width inside the feeding inclined roller is fixed on the inner side of the rotating disk, and the semi-limiting ring is a semi-annular structure, and the upper end wall of the feeding surface of the feeding inclined roller is provided with an arc-shaped docking groove which is adapted to the semi-limiting ring, and the lower end surface of the arc-shaped docking groove is provided with an inclined surface which is continuously inclined downward and connected to the upper end surface of the supporting bracket.

[0010] Furthermore, the upper end surface of the support bracket is an arc-shaped surface adapted to the rim structure, the end wall of the arc-shaped surface close to the rotating disk is provided with a support groove adapted to the feeding assembly, and the upper end of the support bracket away from the loading inclined raceway is fixed with an upward extending side guard.

[0011] Furthermore, a movable baffle is fixed on the end wall of the rotating disk away from the semi-limiting ring, and a fixed baffle is installed on the upper end wall of the discharge port of the loading inclined roller away from the movable baffle. During the rotation of the semi-limiting ring, the movable baffle rotates to the outside of the discharge port of the loading inclined roller. At this time, it cooperates with the fixed baffle to play a side limiting role for the rim that is subsequently transported downward from the inclined surface, so that the rim can fall stably on the support frame.

[0012] Furthermore, the length of the fixed baffle is greater than that of the movable baffle. When the movable baffle rotates to the outside of the discharge port of the loading inclined roller track, the width between the movable baffle and the fixed baffle remains consistent with the width of the rim.

[0013] Furthermore, the feeding assembly includes a support seat installed on the annular electric guide rail, an electric push rod is embedded in the support seat, and the telescopic end of the electric push rod is fixed with a support seat that is compatible with the supporting groove. The upper end surface of the support seat is an arc-shaped surface, and a plurality of supporting rollers are distributed on the arc-shaped surface.

[0014] Furthermore, a push plate with the same structure is rotatably installed on the bottom end wall of the side guard back away from the supporting groove. The inner end of the push plate is rotatably installed on the bottom end of the side guard back through a transmission shaft. A driving motor for rotating the transmission shaft is fixedly installed on the supporting bracket, and the driving end of the driving motor and the transmission shaft can be linked by a meshing gear set to enable the driving motor to drive the push plate to flip left and right.

[0015] Furthermore, a discharging inclined roller track corresponding to the position of the push plate is installed on the side of the annular electric guide rail away from the loading inclined roller track, and a discharging surface is provided at the bottom of the discharging inclined roller track, which is inclined downward and away from the push plate.

[0016] The present invention also proposes a material feeding and conveying method for forklift wheel rim processing, comprising the following steps:

[0017] Step 1: Loading and positioning: The rim to be processed is conveyed on an inclined surface by the loading inclined roller. The material is flipped and shifted by the material shifting assembly at the discharge port of the loading inclined roller. The rim is continuously conveyed to the support frame at preset intervals.

[0018] Step 2: Positioning and conveying: The support seat is rotated to the bottom of the support frame through the circular electric guide rail, and the support seat is driven upward by the electric push rod. The support seat passes through the support groove and supports the rim upward to complete the positioning between the rim and the support seat. The rim is then conveyed to one side of the roll forming machine to complete the loading;

[0019] Step 3: Rolling and discharging processing: After the rolling is completed, the circular electric guide rail is continuously operated to transport the rolled rim along the circular direction of the circular electric guide rail, and the downward-turned pusher plate transports the rim to the side of the discharging inclined roller, forming a continuous production line of loading, conveying, rolling processing and discharging transportation.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] This solution is based on the basic process of rim rolling processing. It forms a production line of continuous loading, conveying, rolling processing and discharging conveying through the mutual coordination of the loading inclined roller, the annular electric guide rail and the feeding assembly structure, and adds a mutually coordinated material picking assembly and a supporting frame on the side of the discharging port of the loading inclined roller. The rim to be processed is tilted downwardly by the loading inclined roller, and the material is flipped and picked by the material picking assembly. The rim is automatically and continuously conveyed to the supporting frame at preset intervals, and the rim that has been initially positioned is continuously conveyed to the rolling machine by the feeding assembly with continuous intermittent conveying. Multiple feeding assemblies are evenly spaced and rely on the annular operation of the annular electric guide rail to realize that during the rim loading process, the rim conveyed to the rolling machine is synchronously rolled. The unloading process after rolling is carried out synchronously with the loading process and the rolling process. The flexibility between each process is strong, which greatly shortens the rolling processing time of one time.

[0022] Regarding the rim loading process, it should be noted that in the initial state, the semi-limiting ring is arranged close to one side of the supporting frame, which is used to intercept the rim at the bottom end of the loading inclined raceway discharge port, and intercept the previous rim during its counterclockwise rotation and change of position, so that the bottom rim automatically falls from the inclined surface onto the supporting frame without the constraint of the semi-limiting ring. The purpose is to realize automatic and orderly loading of the rims without relying on an external handling and grasping mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work shall fall within the scope of protection of the present invention.

[0034] Example 1: The existing upper discharge conveying structure can only receive the next workpiece after the previous workpiece is rolled and transferred to the next process. The operational flexibility and continuity are poor, and the rolling processing time is prolonged. The following technical solution is now proposed:

[0035] The present invention discloses a feeding and conveying device for forklift wheel rim processing, please refer to Figure 1-Figure 2 , including a feeding inclined roller 1 for continuously feeding the rim 2, and an annular electric guide rail 5 arranged below and perpendicular to the feeding inclined roller 1. A plurality of feeding components are evenly distributed on the annular electric guide rail 5 and move circumferentially with the annular electric guide rail and are used to transport the rim 2. A support bracket 4 is installed above the annular electric guide rail 5 and is located at the discharge port of the feeding inclined roller 1;

[0036] See also Figure 3 The upper end surface of the support bracket 4 is an arc-shaped surface adapted to the structure of the rim 2. The end wall of the arc-shaped surface close to the rotating disk 31 is provided with a supporting groove 401 adapted to the feeding assembly. The width of the supporting groove 401 is much smaller than the outer diameter of the rim 2, and the upper end of the support bracket 4 away from the feeding inclined raceway 1 is fixed with an upward extending side guard 402.

[0037] See also Figure 3-Figure 4 A feeding surface is provided at the bottom of the feeding inclined roller 1, which is inclined downward toward the side of the support bracket 4. A material shifting assembly 3 is rotatably installed at the discharge port of the feeding inclined roller 1 near the side of the support bracket 4. The material shifting assembly 3 includes a rotating disk 31 that is rotationally driven and installed on the inner wall of one side of the feeding inclined roller 1. A semi-limiting ring 32 is fixed on the inner side of the rotating disk 31, which is coaxial with the rotating disk and consistent with the internal feeding width of the feeding inclined roller 1. In the initial state, the semi-limiting ring 32 is arranged close to the side guard back 402.

[0038] See also Figure 6 The feeding assembly includes a supporting seat 6 installed on the annular electric guide rail 5, and an electric push rod 7 is embedded in the supporting seat 6. The telescopic end of the electric push rod 7 is fixed with a supporting seat 8 that is compatible with the supporting groove 401. The upper end surface of the supporting seat 8 is an arc surface, and a plurality of supporting rollers 801 are distributed on the arc surface.

[0039] The overall working principle is: please refer to Figure 1 、 Figure 2 and Figure 4、 Figure 5 , through the mutual coordination of the structures of the feeding inclined roller 1, the annular electric guide rail 5, and the supporting seat 8, a continuous production line of feeding, conveying, rolling processing and discharging conveying is formed, and a mutually coordinated material shifting component 3 and a supporting frame 4 are added on one side of the discharging port of the feeding inclined roller 1. When the rim 2 to be processed is automatically conveyed downward by the feeding surface inclined downwardly arranged on the feeding inclined roller 1, the material is flipped by the material shifting component 3, and the rim 2 is automatically and continuously conveyed to the supporting frame 4 at preset intervals, and the supporting frame 8 is continuously and intermittently conveyed by the annular electric guide rail 5;

[0040] One of the feeding components moves to the bottom of the support bracket 4, and the electric push rod 7 is used to drive the supporting seat 8 upward. The supporting seat 8 passes through the supporting groove 401 to push the rim 2 upward, completing the positioning between the rim 2 and the supporting seat 8, and transporting the rim 2 after preliminary positioning to the rolling machine. Multiple feeding components are evenly spaced, so that during the loading process of the rim 2, the rim 2 transported to the rolling machine is synchronously subjected to the rolling operation, and relying on the annular operation of the annular electric guide rail 5, the feeding component for transporting the rim 2 to and from the rolling machine moves in an annular circumferential direction along the annular electric guide rail 5. The unloading process after rolling is carried out synchronously with the loading process and the rolling process. The processes are highly flexible, which greatly shortens the rolling processing time.

[0041] Example 2: This example provides the following structural supplements and detailed descriptions for the automatic loading and conveying process in Example 1:

[0042] See also Figure 3-Figure 5 The semi-limiting ring 32 is a semi-annular structure. The upper end wall of the feeding surface of the feeding inclined roller 1 is provided with an arc-shaped docking groove 101 adapted to the semi-limiting ring 32. The inner and outer end walls of the semi-limiting ring 32 are provided with a flexible anti-wear thin layer. The lower end surface of the arc-shaped docking groove 101 is provided with an inclined surface that continuously slopes downward and is connected to the upper end surface of the support bracket 4. A movable baffle 33 is fixed on the end wall of the rotating disk 31 on the side away from the semi-limiting ring 32. An empty slot for the rotating disk 31 and the movable baffle 33 to rotate is provided on the feeding inclined roller 1. A fixed baffle 102 is installed on the upper end wall of the discharge port of the feeding inclined roller 1 on the side away from the movable baffle 33;

[0043] In the initial state, the semi-limiting ring 32 is arranged close to the side stop 402, and the lower end of the semi-limiting ring 32 is against the inclined surface of the bottom end of the arc-shaped docking groove 101. The rim 2 is transported downward by the feeding inclined roller 1, and the rim 2 at the bottom of the feeding surface is blocked and limited by the semi-limiting ring 32. At this time, the semi-limiting ring 32 is rotated 180° clockwise. The rotation of the semi-limiting ring 32 isolates the lower rim 2 from the upper rim 2. Due to the annular structure of the semi-limiting ring 32, the lower rim 2 is always located on the semi-limiting ring during the rotation of the semi-limiting ring 32. 32, and flexible anti-wear thin layers are added inside and outside the semi-limiting ring 32, which, in conjunction with its own circumferential rolling mode, effectively prevent the semi-limiting ring 32 from causing friction to the two rims 2 below during rotation, thereby achieving lossless transportation. When the semi-limiting ring 32 changes its position, the bottom end of the semi-limiting ring 32 is adapted to the arc-shaped docking groove 101, and the arc surface on the support bracket 4 is lower than the inclined surface at the discharge port 1. At this time, the exposed rim 2 is transported downward from the inclined surface and falls directly onto the support bracket 4, and the side back 402 intercepts the falling rim 2.

[0044] The length of the fixed baffle 102 is greater than that of the movable baffle 33. When the movable baffle 33 rotates to the outside of the discharge port of the loading inclined roller 1, the width between the movable baffle 33 and the fixed baffle 102 is consistent with the width of the rim 2. During the rotation of the semi-limiting ring 32, the movable baffle 33 rotates to the outside of the discharge port of the loading inclined roller 1. At this time, in conjunction with the fixed baffle 102, it plays a side limiting role for the rim 2 subsequently transported downward from the inclined surface, so that the rim 2 can fall stably on the support frame 4.

[0045] After the wheel rim 2 falls on the supporting frame 4, the annular electric guide rail 5 is started, and one of the feeding assemblies moves to the bottom of the supporting frame 4, and the electric push rod 7 is used to drive the supporting seat 8 upward, and the supporting seat 8 passes through the supporting groove 401 to push the wheel rim 2 upward to complete the positioning between the wheel rim 2 and the supporting seat 8. At this time, the material diverter assembly 3 is rotated counterclockwise, and the movable baffle 33 is rotated upward to disengage from the wheel rim 2, and the wheel rim 2 on the supporting seat 8 can be transported to the side of the rolling machine through the annular electric guide rail 5. The next supporting seat 8 is synchronously transported to the bottom of the supporting frame 4, and after the material diverter assembly 3 is reset counterclockwise, the next wheel rim 2 enters its inner side through the exposed end of the semi-limiting ring 32, and the cycle is repeated. The clockwise rotation of the material diverter assembly 3 is repeated to complete the automatic loading of the wheel rim 2, that is, during the loading process of the wheel rim 2, the wheel rim 2 delivered to the rolling machine is synchronously rolling. The multiple feeding assemblies are evenly spaced to realize the synchronous loading and rolling actions.

[0046] Note that the annular electric guide rail 5 is arranged below the side of the loading inclined roller 1, and the rolling machine is arranged above the edge of the annular electric guide rail 5. During the rolling process, the supporting seat 8 is placed behind the rolling machine, and the electric push rod 7 is driven downward, and the supporting seat 8 is separated from the rolling machine. The arrangement of the annular electric guide rail 5 and the supporting seat 8 does not affect the rolling process. After the rolling process is completed, the supporting seat 8 is reset upward to support the rim 2 after the rolling process.

[0047] A push plate 9 having the same structure as that of the side guard back 402 is rotatably installed on the bottom end wall away from the supporting groove 401 on one side. The inner end of the push plate 9 is rotatably installed on the bottom end of the side guard back 402 through the transmission shaft 901. A driving motor for rotating the transmission shaft 901 is fixedly installed on the supporting bracket 4. The driving end of the driving motor and the transmission shaft 901 can be linked by a meshing gear set to realize that the driving motor drives the push plate 9 to flip left and right. A discharging inclined roller corresponding to the position of the push plate 9 is installed on the side of the annular electric guide rail 5 away from the loading inclined roller 1. The bottom of the discharging inclined roller is provided with a discharging surface inclined downward away from the side of the push plate 9;

[0048] After the rolling is completed, the annular electric guide rail 5 is continuously operated to convey the rolled rim 2 along the annular direction of the annular electric guide rail 5. Multiple conveying components are evenly distributed. This embodiment provides 4 groups of conveying components on the support bracket. When one of the conveying components is located at the support bracket 4, another conveying component is located at the rolling machine, and another conveying component is located at the push plate 9 for unloading. The last conveying component is located between the rolling process and the unloading work, as a waiting conveying component to shorten the operation time between each process. During the discharging conveying, the downward-turned push plate 9 pushes the rim 2 toward the side of the discharging inclined roller to form a production line of continuous loading, conveying, rolling processing and discharging conveying.

[0049] In combination with Example 1, this embodiment further proposes a material feeding and conveying method for forklift wheel rim processing, comprising the following steps:

[0050] Step 1: Loading and positioning: The rim 2 to be processed is conveyed on an inclined surface by the loading inclined roller 1. The material is flipped and shifted by the material shifting assembly 3 at the discharge port of the loading inclined roller 1. The rim 2 is continuously conveyed to the support frame 4 at preset intervals.

[0051] Step 2: Positioning and conveying: The supporting seat 8 is rotated to the bottom of the supporting frame 4 by the annular electric guide rail 5, and the supporting seat 8 is driven upward by the electric push rod 7. The supporting seat 8 passes through the supporting groove 401 to support the rim 2 upward, completing the positioning between the rim 2 and the supporting seat 8, and then the rim 2 is conveyed to one side of the roll forming machine to complete the loading;

[0052] Step 3: Rolling and discharging processing: After the rolling is completed, the annular electric guide rail 5 is continuously operated to transport the rolled rim 2 along the annular direction of the annular electric guide rail 5, and the downward-turned pusher plate 9 transports the rim 2 toward the side of the discharging inclined roller to the temporary storage area or the next processing step, forming a continuous production line of loading, conveying, rolling processing and discharging transportation.

[0053] The wheel rim 2 of the present invention is automatically fed to the material carrier 2 by the feed inclined roller 1 and the feeding device 3, and the wheel rim 2 of the present invention is automatically fed to the material carrier 2 by the feed inclined roller 1 and the feeding device 3.

[0054] The rim 2 after preliminary positioning is then continuously conveyed to the rolling machine through the continuous and intermittent conveying feeding assembly 8. Multiple feeding assemblies are evenly spaced, so that during the loading process of the rim 2, the rim 2 conveyed to the rolling machine is synchronously subjected to the rolling operation, and relying on the circular operation of the annular electric guide rail 5, the unloading process after rolling is carried out synchronously with the loading process and the rolling process. The flexibility between each process is strong, which greatly shortens the rolling processing time.

[0055] The above are only preferred specific implementation methods of the present invention; however, the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved conception of the present invention shall be covered within the protection scope of the present invention.
