Description

Technical Field

[0001] This utility model relates to the field of material cutting technology, specifically to a special material cutting machine for shaft production lines. Background Technology

[0002] In shaft production lines, there are usually conveyor belts and various processing equipment around the conveyor belts. Since shafts are prone to rolling and shifting during transmission, support frames are usually installed on the conveyor belts. Shafts can be placed on the support frames for transmission. During transmission, robotic arms grab the shafts from the conveyor belts for processing. However, since production lines usually use multi-station synchronous processing, it is difficult to control the feeding rhythm between different stations, which can easily lead to feeding conflicts between different stations and affect production efficiency. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a special unloading machine for shaft production lines, thereby solving the problems mentioned in the background art.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A special unloading machine for shaft production lines includes a conveying device. Support plates are installed on both sides of the conveying device, and a receiving device is installed between the two support plates above the conveying device. A guiding device is provided above the receiving device to receive multiple shafts and guide them onto the receiving device. The receiving device places the shafts onto the conveying device by rotating. A blocking device is also provided on one side of the receiving device. When the receiving device drives one of the shafts to rotate downwards, the blocking device can temporarily prevent the remaining shafts from remaining in the waiting position of the guiding device and the receiving device, so that multiple shafts enter the receiving device in sequence.

[0006] As a preferred embodiment of a special unloading machine for shaft production lines, the receiving device includes a rotary cylinder installed on one side of one of the support plates. The rotary cylinder is connected to a rotating shaft, and the other end of the rotating shaft is rotatably connected to another support plate through a bearing. Several receiving discs are sleeved on the rotating shaft, and the receiving discs are provided with receiving ports for receiving shaft parts. The receiving discs are located above the conveying device.

[0007] As a preferred embodiment of a special unloading machine for shaft production lines, the feeding device includes a first connecting plate mounted on one of the support plates. A feeding plate is installed at the end of the first connecting plate away from the support plate. The feeding plate is positioned higher than the receiving tray, and the feeding plate extends downward in the direction of the receiving tray, such that the gap between the feeding plate and the receiving tray is smaller than the diameter of the shaft.

[0008] As a preferred embodiment of a special unloading machine for shaft production lines, the material blocking device includes a second connecting plate installed between two support plates. Several arc-shaped baffles are installed on the second connecting plate. The positions of the arc-shaped baffles correspond one-to-one with the receiving tray, and each arc-shaped baffle is adjacent to the outer surface of the receiving tray, such that the gap between the arc-shaped baffle and the receiving tray is smaller than the diameter of the shaft. A vertical baffle is installed at the top of the arc-shaped baffle. The vertical baffle is located above the receiving tray and adjacent to the guide plate. The distance between the guide plate and the vertical baffle is slightly larger than the diameter of the shaft.

[0009] As a preferred embodiment of a special unloading machine for shaft production lines, the conveying device includes a mounting frame, with connecting shafts movably connected to both ends of the mounting frame. Sprockets are mounted on both ends of the connecting shafts, and the sprockets on corresponding sides of the two connecting shafts are connected by chain drive. Several support frames for placing shafts are mounted on both chains, and the support frames are spaced apart along the length of the chains. A drive motor is also mounted on one side of the mounting frame, and the drive motor is drive-connected to the connecting shafts.

[0010] As a preferred embodiment of a special unloading machine for shaft production lines, the output shaft of the drive motor is equipped with a drive wheel, and the end of the connecting shaft near the drive motor is equipped with a driven wheel. The drive wheel and the driven wheel are connected by a synchronous belt drive.

[0011] As a preferred embodiment of a special unloading machine for shaft production lines, the discharge end of the conveying device is equipped with a stacking device for receiving shaft parts. The stacking device includes a stacking plate disposed at the discharge end of the conveying device, and a discharge plate is installed at the end of the stacking plate away from the conveying device. The height of the discharge plate is higher than that of the stacking plate.

[0012] As a preferred embodiment of a special unloading machine for shaft production lines, the bottom of the stacking plate is also equipped with a pushing device for pushing the shaft to the discharge plate. The pushing device includes a mounting base mounted on a mounting frame, a drive cylinder mounted on the mounting base, a push plate mounted on the output end of the drive cylinder, and a push groove opened on the stacking plate corresponding to the position of the push plate. The length of the push groove is less than the length of the shaft. The drive cylinder can drive the push plate through the push groove to drive the shaft to the discharge plate.

[0013] As a preferred embodiment of a special unloading machine for shaft production lines, both the stacking plate and the discharge plate are inclined, and both the stacking plate and the discharge plate are inclined downwards in the direction away from the conveying device.

[0014] As a preferred solution for a special feeding machine for shaft production lines, the top of the support frame has a V-shaped structure.

[0015] The beneficial effects of this utility model are:

[0016] This invention adds an auxiliary unloading function to the existing conveying device. Robots at different workstations can place shafts on the guide plate, which guides the shafts to the receiving tray, which then returns the shafts to the conveying device. Specifically, this invention, through the coordinated action of the vertical baffle and the guide plate, ensures that multiple shafts enter the receiving tray sequentially and orderly. When the receiving tray rotates one shaft downwards, the remaining shafts are temporarily blocked by the vertical baffle and remain in the waiting position on the guide plate and receiving tray. Once the receiving tray's receiving port rotates back upwards, the next shaft can be received, effectively solving the problem of unloading conflicts between different workstations.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1As shown, this utility model provides a special unloading machine for shaft production lines, including a conveying device 1. Support plates 2 are installed on both sides of the conveying device 1. A receiving device 3 is installed between the two support plates 2, located above the conveying device 1. A guiding device 4 is arranged above the receiving device 3. Robots at different workstations can place shafts 100 onto the guiding device 4, which then guides the shafts 100 into the receiving device 3. The receiving device 3 can then return the shafts 100 to the conveying device 1. A material blocking device 6 is also provided on the side of the material receiving device 3. Through the coordinated action of the material guiding device 4 and the material blocking device 6, it can be ensured that multiple shafts 100 enter the receiving device 3 in an orderly manner. When the receiving device 3 drives one of the shafts 100 to rotate downward, the remaining shafts 100 will be temporarily blocked by the material blocking device 6 and remain in the waiting position of the material guiding device 4 and the receiving device 3. When the receiving port 34 of the receiving device 3 rotates back to the top, the next shaft 100 can be received, which effectively solves the problem of material feeding conflict between different workstations.

[0030] like Figure 3 As shown, the receiving device 3 specifically includes a rotary cylinder 31 installed on one side of one of the support plates 2. The rotary cylinder 31 is connected to a rotary shaft 32. The other end of the rotary shaft 32 is rotatably connected to another support plate 2 through a bearing. Several receiving discs 33 are sleeved on the rotary shaft 32. The receiving port 34 is opened on the receiving disc 33, and the receiving disc 33 is located above the conveying device 1. In the initial state, the receiving port 34 of the receiving disc 33 is located at the top and close to the feeding device 4. When the robot places the shaft 100 on the feeding device 4, the shaft 100 will enter the receiving port 34 of the receiving disc 33 along the feeding device 4. At this time, the rotary cylinder 31 is activated. The rotary cylinder 31 will drive the receiving disc 33 to rotate through the rotary shaft 32, so that the receiving port 34 rotates to the bottom, thereby putting the shaft 100 back onto the conveying device 1. Then the rotary cylinder 31 drives the receiving port 34 of the receiving disc 33 back to the top to pick up the next shaft 100.

[0031] Preferably, two receiving trays 33 are used in this embodiment, and the two receiving trays 33 are respectively used to support the two ends of the shaft 100, so that the shaft 100 can be placed stably.

[0032] Specifically, the feeding device 4 includes a first connecting plate 41 mounted on one of the support plates 2. A feeding plate 42 is mounted on the end of the first connecting plate 41 away from the support plate 2. The robot can place the processed shaft 100 on the feeding plate 42, and the feeding plate 42 can guide the shaft 100 into the receiving tray 33.

[0033] Preferably, in order to drive the shaft 100 from the feed plate 42 into the receiving port 34 of the receiving tray 33, the feed plate 42 in this embodiment is inclined downward, so that the bottom end of the upper surface of the feed plate 42 is flush with or slightly higher than the receiving tray 33. In addition, in order to prevent the shaft 100 from falling out of the gap between the feed plate 42 and the receiving tray 33, the gap between the two should be smaller than the diameter of the shaft 100.

[0034] Specifically, the material blocking device 6 includes a second connecting plate 61 installed between two support plates 2. Several arc-shaped baffles 62 are installed on the second connecting plate 61. The positions of the arc-shaped baffles 62 correspond one-to-one with those of the receiving tray 33, and each arc-shaped baffle 62 is adjacent to the outer surface of the receiving tray 33, so that the gap between the arc-shaped baffle 62 and the receiving tray 33 is smaller than the diameter of the shaft 100. When the receiving tray 33 drives the shaft 100 to rotate downward, the arc-shaped baffles 62 can effectively prevent the shaft 100 from falling out of the receiving tray 33 during rotation.

[0035] Meanwhile, a vertical baffle 63 is installed at the top of the arc-shaped baffle 62. The feed plate 42 and the vertical baffle 63 are located on the upper sides of the receiving tray 33, respectively. The vertical baffle 63 can prevent other shafts 100 from falling at the feed plate 42. The distance between the feed plate 42 and the vertical baffle 63 is slightly larger than the diameter of the shaft 100, allowing only a single shaft 100 to enter the receiving port 34 of the receiving tray 33 at a time.

[0036] like Figure 2 As shown, the conveying device 1 specifically includes a mounting frame 11. Both ends of the mounting frame 11 are movably connected to a connecting shaft 12. Both ends of the connecting shaft 12 are equipped with sprockets 13. The sprockets 13 on the corresponding sides of the two connecting shafts 12 are connected by a chain 14. Several support frames 15 are installed on the two chains 14. The support frames 15 are distributed at intervals along the length of the chain 14. When the receiving plate 33 drives the shaft 100 to rotate downward, the shaft 100 will be placed on the support frame 15, and the support frame 15 continues to follow the chain 14 to the discharge end for unloading.

[0037] Preferably, the top of the support frame 15 in this embodiment adopts a V-shaped structure. The V-shaped structure can increase the contact area of ​​the shaft 100, so that the shaft 100 is placed more stably on the support frame 15.

[0038] A drive motor 16 is also installed on one side of the mounting bracket 11. The drive motor 16 is connected to the connecting shaft 12. When the drive motor 16 drives the connecting shaft 12 to rotate, the connecting shaft 12 drives the chain 14 to rotate through the sprocket 13, thereby driving the support bracket 15 to move.

[0039] More specifically, the transmission method between the drive motor 16 and the connecting shaft 12 can be as follows:

[0040] The output shaft of the drive motor 16 is equipped with a drive wheel 17, and the end of the connecting shaft 12 near the drive motor 16 is equipped with a driven wheel 18. The drive wheel 17 and the driven wheel 18 are connected by a synchronous belt 19. When the drive motor 16 starts, the drive motor 16 will drive the drive wheel 17 to rotate, and the drive wheel 17 will drive the driven wheel 18 and the connecting shaft 12 to rotate through the synchronous belt 19, thereby realizing the transmission connection between the drive motor 16 and the connecting shaft 12.

[0041] like Figure 5 As shown, this embodiment also includes a stacking device 5 for receiving the shaft 100. The stacking device 5 specifically includes a stacking plate 51 disposed at the discharge end of the conveying device 1. When the conveying device 1 moves to the discharge end, the chain 14 will drive the support frame 15 to rotate downward. The front end of the stacking plate 51 is provided with a through groove corresponding to the position of the support frame 15. The support frame 15 can pass through the through groove and continue to rotate downward. The shaft 100 on the support frame 15 will remain on the stacking plate 51.

[0042] More preferably, in order to prevent the shaft 100 on the stacking plate 51 from falling off, the stacking plate 51 is inclined, and the shaft 100 will accumulate at the rear end of the stacking plate 51.

[0043] Meanwhile, to facilitate the next process or assembly line processing, a pushing device 7 can also be installed at the bottom of the stacking plate 51 in this embodiment. The pushing device 7 specifically includes a mounting base 71 installed on the mounting frame 11, a driving cylinder 72 installed on the mounting base 71, a push plate 73 installed at the output end of the driving cylinder 72, and a push groove 53 opened on the stacking plate 51 corresponding to the position of the push plate 73. At the same time, a discharge plate 52 is installed at the end of the stacking plate 51 away from the conveying device 1. When the driving cylinder 72 is started, the driving cylinder 72 drives the driving push plate 73 through the push groove 53 and drives the shaft 100 on the stacking plate 51 to the discharge plate 52. The discharge plate 52 is inclined downward, thereby guiding the shaft 100 into the next process or assembly line.

[0044] Preferably, in this embodiment, the length of the push groove 53 is less than the length of the shaft 100, thereby preventing the shaft 100 on the stack plate 51 from falling out of the push groove 53.

[0045] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
